OBJECTIVE To examine the associations between exercise capacity (EC), cardiovascular (CV) risk factors and disease-related variables in axial spondyloarthritis (AxSpA) patients. METHODS In this cross-sectional controlled study, CV risk profile data, physical activity, 10-year CV event risk estimated by the Framingham model and Ankylosing Spondylitis Disease Activity Score - C-reactive protein were recorded. A maximal treadmill exercise test by Bruce protocol was administered. Analyses of covariance were performed with adjustments for age, smoking status and physical activity level. Linear regression analysis was performed to study the association between EC and related CV risk factors. RESULTS Thirty-eight patients and 38 age-gender matched controls were recruited between May and October 2014. Patients had significantly lower EC than controls (MD 2.2; metabolic equivalents 0.91-3.49; P = .001). The difference remained significant after adjustments (P = .001). There were significant correlations between EC and age, 10-year CV event risk, body mass index (BMI) and waist circumference for patients and controls (P

Background/aim The aim of this study was to evaluate the effects of a 6-month treatment regimen with exenatide on the lipid profile, high-sensitivity C-reactive protein (hsCRP), carotid intima media thickness (CIMT), visceral adiposity, and nonalcoholic fatty liver disease (NAFLD), all of which are important cardiovascular risk factors. Materials and methods This study included 45 obese patients with type 2 diabetes mellitus (T2DM). Baseline clinical findings, laboratory parameters, and ultrasonography findings were recorded. An exenatide recipe was given twice daily to the patients and, after 6 months of therapy, the same variables were compared. The compared parameters were lipid profiles, hsCRP, aspartat aminotransferase, alanine aminotransferase, gamma-glutamyl transferase, liver craniocaudal diameter, visceral fat volume, subcutaneous fat thickness, and CIMT. Liver diameter, visceral fat volume, subcutaneous fat thickness, and CIMT were measured by ultrasonography. Results After therapy, statistically significant improvements were achieved in lipid profile, hsCRP, liver enzymes, body mass index, and waist and hip circumferences. Also, statistically significant decreases were obtained in liver craniocaudal diameter, subcutaneous fat thickness, visceral fat volume, and CIMT. The reduction of CIMT and liver diameter were not correlated with BMI and HbA1c reduction. Conclusion This study showed improvement in lipid profile and hsCRP levels with exenatide treatment. We also showed decrease in both visceral fat volume and subcutaneous fat thickness. We demonstrated significant decrease in liver enzymes with significant decrease in liver diameter. These findings support the use of exenatide in patients with NAFLD and T2DM. Additionally, this study showed that exenatide treatment given twice daily reduces CIMT in obese T2DM patients.

Background To investigate whether any relationship between local alveolar bone density and maxillary canine impaction using gray values from cone beam computed tomography. Material and Methods The cone beam computed tomography images of 151 patients were retrospectively evaluated. Maxillary canine was defined as an impacted tooth when root formation was complete and the patient’s age older than 13 or the other side of the maxillary canine has completely erupted. Similarly, complete eruption was defined as the tooth in its expected occlusion and position. Using the cone beam computed tomography software, the region of interest which was 5 mm2 in area, was placed in the trabecular bone on cross sectional cone beam computed tomography images and the gray value measurements were recorded. After measuring the gray values of all the teeth, the images were grouped according to the field of view size. Comparison of the gray values of impacted and non-impacted teeth was made between images with the same field of view size. Results A total of 151 patients, 101 (66.9%) female and 50 (33.1%) male, were included in the study. The mean age of the patients was 24.94 ±13.9. In images with a 40X40 field of view, the gray values of the impacted canine teeth were higher than the gray values of the non-impacted ones and statistically significant difference was found between them (p=0.003). However no statistically significant difference was found between the gray values of impacted and non-impacted canine teeth in 60x60 and 100x50 field of view (p=0.197, p=0.170, respectively). Conclusions We suggest using the smallest field of view size when evaluating bone density using gray values from cone beam computed tomography images and we support the idea that the local increased bone density may influence on impaction. Key words:Cone-beam computed tomography, tooth, impacted, bone density, maxilla, image processing, computer-assisted.

Objective: We sought to evaluate neurologic symptoms and findings in patients with COVID- 19 infection hospitalized in a ward and intensive care unit (ICU). Methods: This study was designed as a prospective study. Hospitalized COVID-19 rRt-PCR positive patients in the ward and ICU were included in the study. A 54-item questionnaire was used to evaluate the patients. Patients were examined within 3 hours of hospitalization. Results: A total of 379 patients were included in the study. The mean age of the patients was 56.1 ± 17.8. 89 of the patients were in intensive care. At least one general symptom was recorded in 95.5% of patients. The most common neurologic symptoms were myalgia (48.5%), headache (39.6%), anosmia (34.8%), and dysgeusia (34%). Neurological symptoms in ICU patients were higher than in the ward. 53.6% of patients had comorbidities. Discussion: This study indicated that the prevalence of neurological symptoms was very high in patients with COVID-19. The percentage of neurological symptoms and findings was higher in patients hospitalized in ICU.

Objective: The aim compares the blood gases, vital signs, mechanical ventilation requirement, and length of hospitalization in patients with hypertensive pulmonary edema treated with standard oxygen therapy (SOT) and high-flow oxygen therapy (HFOT). Methods: This prospective observational study was conducted in patients with tachypneic, hypoxemic, hypertensive pulmonary edema. The patients' 0th, 1st, and 2nd hour blood gas results; 0th, 1st, and 2nd hour vital signs; requirement of endotracheal intubation, length of hospitalization, and the prognosis were recorded on the study form. Results: A total of 112 patients were included in this study, of whom 50 underwent SOT and 62 received HFOT. The initial blood gas analysis revealed significantly lower levels of pH, PaO2, and SpO2 and significantly higher levels of PaCO2 in the HFOT group. Patients in the HFOT group had significantly higher respiratory rate and pulse rate and significantly lower SpO2 values. The recovery of vital signs was significantly better in the HFOT group (p

Background/aim Malnutrition is an important and commonly seen prognostic factor in patients with cirrhosis. The diagnosis of malnutrition in cirrhosis patients may be challenging, and an easily measured and widely usable marker is lacking. Prealbumin, however, is an easily measured marker. In the current study we measured prealbumin levels in cirrhotic patients with no clinically apparent malnutrition and used it as a malnutrition marker. Another aim of this study was to evaluate the effect of nutritional support on patient with low prealbumin levels. Materials and methods Fifty-two patients with Child A and Child B cirrhosis were selected for the study. Prealbumin levels were studied, and Child and MELD scores were calculated. Patients with prealbumin levels ˂180 mg/L were considered to have malnutrition, and two different types of nutritional products were given to these patients. The patients given nutritional support were investigated a month later, and parameters were compared. Results According to the prealbumin threshold of 180 mg/L, malnutrition frequencies were 59.3% for Child A and 95% for Child B cirrhosis. After the provision of nutritional support statistically significant improvements in albumin and INR levels were detected. In addition, the MELD score decreased; however, it was not statistically significant (P: 0.088). A statistically significant decrease in the MELD score was only obtained in patients with Child B cirrhosis (P: 0.033). When the oral replacement therapies were investigated separately, a statistically significant decrease in MELD scores was detected with product 1 (P: 0.043). Conclusion Prealbumin can be used as an easily measured parameter for earlier detection of malnutrition in patients with cirrhosis and without clinically apparent malnutrition. Oral nutritional support, especially with products containing relatively high carbohydrate levels and low protein, may have a favorable effect on MELD scores.

Mycobacterium bovis causes gastrointestinal tuberculosis by being transmitted through consumption of infected milk and dairy products, mostly in developing countries, and can spread to the other neighbourhood intra-abdominal tissues and organs. In addition to the symptoms such as weight loss, weakness, abdominal pain, and chronic diarrhea in female patients with abdominal tuberculosis, findings such as pelvic mass, ascites and CA-125 elevation may be encountered. Patients with these symptoms usually preliminary diagnosed as having ovarian cancer. It is very important to distinguish between these two diseases quickly, which have different treatment protocols. In this case report, a case of intra-abdominal tuberculosis caused by M.bovis, whose diagnosis was confirmed by microbiological methods with the findings mimicking ovarian cancer such as weight loss, ascites, pelvic mass and increased CA-125 was presented. Tuberculosis was considered in the differential diagnosis of a 23-yearold female patient with abdominal pain, weight loss, ascites, pelvic mass, and elevated CA-125 (643.9 U/ml) findings and a mass in the left tubaovarian region on abdominal CT. The ileum biopsy sample taken during colonoscopy and ascitic fluid sample taken with paracentesis were sent to our laboratory for acid-fast bacilli (AFB) staining and tuberculosis culture. In our laboratory, samples were incubated in both liquid culture system [BACTEC MGIT 320 Mycobacteria Culture System (Becton Dickinson,USA)] and solid culture medium [Lowenstein-Jensen Medium (Becton Dickinson,USA)] and AFB smears were performed. While AFB smears were negative, ileum biopsy material showed growth on day 14 and ascitic fluid sample on day 11 in liquid culture medium. AFB smear was prepared from broth and red bacilli were seen on a blue background that formed cord factor. The bacillus was identified as Mycobacterium tuberculosis complex by the immunochromatographic rapid test [BD MGIT TBc Identification Test (BD,USA)]. The anti-tuberculosis drug treatment was initiated with the diagnosis of intra-abdominal tuberculosis. The isolated bacillus was found to be sensitive to isoniazid, rifampicin, ethambutol and resistant to streptomycin, according the drug susceptibility test results. Subspecies identification of M.tuberculosis complex was investigated by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) but could not be determined by this method. Genotyping was performed with the GenoType MTBC VER 1.X (Hain Lifescience, HardwiesenstraBe, Germany) kit. The isolate was identified as M.bovis. In the follow-up of the patient three months later, it was determined that tumor markers, ascitic fluid and intra-abdominal lymph nodes regressed significantly and the mass in the left ovary completely disappeared. In this report, we presented a case with intra-abdominal tuberculosis whose clinical, radiological and laboratory findings mimic ovarian cancer to imply the importance of microbiological diagnosis.

Objective: To evaluate the comparison of direct-acting oral anticoagulants (DOACs) and warfarin for their effects on major bleeding and hospital outcomes in patients with acute nonvariceal upper gastrointestinal bleeding (NVUGIB). Study Design: An observational study. Place and Duration of Study: Tekirdag Namik Kemal University Hospital, Hitit University Erol Olçok Education and Research Hospital, between January and December 2021. Methodology: Adult patients prescribed warfarin and DOACs were followed up for one year. Their length of hospital stay, need for intensive care unit admission, need for red blood cell transfusion, and major bleeding rates were compared. Results: Thirty-two patients (61.5%) were user of DOACs (DOAC group), and 20 patients (38.5%) were users of warfarin (warfarin group). No statistically significant difference was determined between patients in warfarin group and DOAC group for the number of packed red blood cells transfused [median 3 (0-6) units, 3 (0-10) units, p=0.229, respectively], length of hospital stay [median 5 days (3-10), and 4.5 days (2-20), p=0.739, respectively], rate of intensive care unit admission [(n=9, 45%; and n=10 (31%), p=0.623, respectively] and the occurrence of major bleeding events (warfarin-70%; DOACs-78%; p=0.529). Conclusion: Major bleeding episodes and hospital outcomes of acute NVUGIB were similar between patients receiving warfarin and DOACs. © 2022 College of Physicians and Surgeons Pakistan.

Background and Aims Personal protective equipment (PPE) decreases the risk of disease contagion, and because of the COVID-19 pandemic, enhanced PPE (EPPE) is widely used during endoscopic procedures including endoscopic retrograde cholangiopancreatography (ERCP). The aim of this study was to investigate the effects of EPPE on ERCP success parameters compared to standard PPE (SPPE). Methods ERCP procedures were evaluated retrospectively and ERCP outcomes were compared for similar time periods as before and after the COVID-19 pandemic. Primary outcomes were cannulation time, number of cannulation attempts, cannulation success rate, difficult cannulation rate, undesired pancreatic duct cannulation rate, ERCP-related adverse events, and length of hospital stay. Results Three hundred and eighty ERCP procedures were examined. One hundred and fifty-nine procedures were excluded due to missing data, previous sphincterotomy or altered anatomy. Of the final eligible sample size of 221 ERCPs, 93 were performed using SPPE and 128 were performed under EPPE. Indications of ERCP and demographic parameters were similar between groups. The majority of the ERCP cases included were for benign biliary obstruction of common bile duct stones (88.7%). No significant differences were detected in overall technical success (91.4% vs 92.2%, p = 0.832), cannulation success rates (94.6% vs 96.8%, p = 0.403), cannulation times (median times of both groups were 3 min, p = 0.824), difficult cannulation rates (37.6% vs 33.6%, p = 0.523), undesired pancreatic duct cannulation rates (29% vs 22.7%, p = 0.593), number of cannulation attempts (2.80 vs 2.71, p = 0.731), ERCP-related adverse events (9.7% vs 10.9%, p = 0.762), and length of hospital stay (6.63 vs 6.92 days, p = 0.768) between SPPE and EPPE groups, respectively. Conclusion Biliary obstructions of common bile duct stones were the major indication of ERCP in the current study. The use of EPPE had no negative effects on ERCP performance in this patient group. ERCP can be effectively performed under EPPE. WOS:000631771500001 2-s2.0-85102890868 PubMed: 33755824

Diarrhea caused by parasitic agents is common in neonatal calves and leads to significant economic losses in cattle farms worldwide. Cryptosporidium spp. is one of the most frequently detected parasitic agents causing diarrhea in neonatal calves. The aim of this study was to investigate the presence of Cryptosporidium spp. on a dairy farm which a has major diarrhea problem. Samples were collected from calves, cows, drinking bowls, and two different artesian water sources, as well as from the environment. All fecal samples were investigated using Kinyoun acid-fast stained slides and real-time PCR targeting the Cryptosporidium spp. COWP gene. In addition, species identification was performed by nested PCR targeting the Cryptosporidium spp. COWP gene and sequencing. Cryptosporidium spp. was detected in 11 calves (30.55%; 11/36) by real-time PCR and the cows were negative. Among real-time PCR positive samples, only five were also found positive by microscopy. Moreover, Cryptosporidium spp. was found in one of the two artesian water sources and five environmental samples by real-time PCR. Among these positive samples, eight were sequenced. According to the RFLP pattern, BLAST and, phylogenetic analyses, all sequenced samples were Cryptosporidium parvum. These findings show the importance of C. parvum as a cause of calf diarrhea on dairy farms.

Introduction The objective of this study was to investigate the clinical and radiological features and pulmonary function tests (PFTs) in patients with the pulmonary involvement of systemic rheumatic diseases (SRDs). Materials and methods This study was conducted as a retrospective and single-center study. Patients diagnosed with an SRD and admitted/referred to the department of chest diseases of our hospital between January 2015 and June 2019 were enrolled. All patients were evaluated using High Resolution Computed Tomography (HRCT) and PFT. Result This study included 68 patients (15 males, 53 females) with a mean age of 62.38 ± 12.4 years. Forty-one (60.2%) patients had diagnosis of rheumatoid arthritis (RA), 10 (14.7%) patients had sjogren's syndrome (SS), 8 (11.7%) patients had systemic lupus erythematosus (SLE), 6 (8.8%) patients had systemic sclerosis (SSc), and 3 (4.4%) patients had mixed connective tissue disease (MCTD). While RA, SLE, MCTD patients were more commonly symptomatic, most of the SS patients were asymptomatic. Overall, 30 (44.1%) patients had normal PFT. Although 30 (%44.1) patients were asymptomatic and 30 (%44.1) patients had normal PFTs, at least one imaging finding was found in all patients according to HRCT imaging. "Bronchiectasis" was the most common HRCT finding in RA, followed by "chronic fibrotic changes" and "peribronchial thickening". "Chronic fibrotic changes" and "peribronchial thickening" were the most common changes in SS. Similarly, "peribronchial thickening" was the most common radiologic finding in SLE. As for SSc, "chronic fibrotic changes", "interlobular septal thickening", and "pleural effusion" were the most common radiologic findings. Conclusions Pulmonary involvement in systemic rheumatic diseases can occur with various radiological images even in asymptomatic patients. PFTs can be normal as well as an obstructive, restrictive or mixed pattern can be seen. Heterogeneous and combined HRCT findings can be seen in SRD patients.

The aim of this study was to evaluate the diaphragm thickness in patients with obstructive sleep apnea syndrome (OSAS).This prospective study included patients who underwent polysomnography evaluation for the first time with a clinical suspicion of OSAS. All patients underwent polysomnographic evaluation with a 55-channel Alice 6 computerized system (Respironics; Philips, IL). Diaphragm thickness was measured as the distance between the peritoneum and the pleura using electronic calipers with a 7-12-MHz linear probe (PHILIPS EPIQ 5G).A total of 108 patients (67 males, 41 females) were enrolled in the current study. The mean age of the patients was 48.92 ± 11.47 years. The diaphragm thicknesses were significantly higher in OSAS patients both at end-inspirium and end-expirium compared with the normal group (p 0.05). No significant difference was observed regarding the change level and thickening ratio (%) (p 0.05). When the patients were allocated into OSAS subtypes; diaphragm thicknesses at the end of inspirium and expirium on both sides were significantly higher in the severe OSAS group and OSAS+OHS group compared with the other groups of normal, mild OSAS, and moderate OSAS subgroups (p 0.05 for all). There was no significant difference between the groups regarding the thickening ratio (p 0.05 for all). There was a positive correlation between the severity of OSAS and diaphragm thickness.Diaphragm thickness seems to be increased in OSAS patients and the thickness correlates with the severity of OSAS. However, the thickness ratio of OSAS patients does not differ from that of normal subjects.

A 16-year-old patient sought orthodontic correction for profile improvement and labially inclined maxillary incisors. She had Class II malocclusion, protrusive maxillary and mandibular incisors, and increased overjet and overbite with an American Board of Orthodontics discrepancy index value of 25. She was treated with maxillary premolar extractions and miniscrew-supported en masse retraction assisted with piezoincisions. Extraction spaces (7.5 mm per side) were closed with maximum anchorage in 10 months. Total treatment time was 23 months. Twenty-seven months after debonding, a pink spot was noted at the buccocervial region of the left central incisor. Radiographic evaluation on cone-beam computed tomographic scans revealed a severe case of invasive cervical resorption on both central incisors, around which the piezosurgical cuts had been made. Treatment proceeded with a nonintervention approach and the affected teeth were reinforced with a lingual retainer.

Cross-sectional study. To investigate the role of ultrasonographic measurement of the diaphragm thickness on pulmonary function tests in patients with spinal cord injury (SCI). Rehabilitation center in Ankara, Turkey. A total of 42 patients (34 M, 8 F) with SCI and 20 able-bodied volunteers (8 M, 12 F) were enrolled. Patients with SCI were divided into three groups according to their neurological (injury) levels. All participants underwent ultrasonographic measurements for diaphragm thickness on both sides and spirometric tests for pulmonary functions. The thickness ratio of the diaphragm was also calculated. There were seven patients (5 M, 2 F) in C2–C4 injury group, 14 patients (12 M, 2 F) in C5–T5 group, 21 patients (14 M, 7 F) in T6–L2 group, and 20 able-bodied volunteers (8 M, 12 F). The diaphragms of C2–C4 group were thicker than those of the controls at end-inspirium on the right side (2.7 ± 0.7 mm vs. 2.0 ± 0.5 mm; p = 0.035). The thickness ratios of C2–C4 group were lower than those of controls on the right (0.8 ± 0.4 vs. 1.5 ± 0.5; p = 0.005) and left (0.8 ± 0.5 vs. 1.6 ± 0.7; p = 0.003) sides. For all the pulmonary function tests (except for FEV1/FVC); patients with SCI had worse results than controls; and among the SCI groups, the higher the injury level, the worse the results. Although patients with high-level SCI had worse pulmonary function tests and decreased the contractile capacity of the diaphragm, they had thicker diaphragm muscles than controls. This may have been due to the compensatory effect of the diaphragm (performing its maximum contraction capacity and increasing frequency of inspiration).

Difficulties of self-management in people with MS (pwMS) is considered as one of the most important factors contributing to low rehabilitation efficacy, more severe long-term complications and increase in healthcare costs. Despite the emergence of research in the last decade documenting causes, types, and course of cognitive difficulties in MS disease subtypes, limited evidence is available in the literature for direct comparison of self-management and cognitive deficits. In this study we aimed to investigate the relationship between cognitive performance and self-management in pwMS.PwMS who applied to neurology out-patient clinics of seven different centers were included into study. Multiple Sclerosis Self-Management Scale- Revised (MSSM-R) was used for the assessment of self-management behaviors and Multiple Sclerosis inventory cognition scale (MUSIC) was used for the assessment of cognitive performance and fatigue.In this study, 194 (144 female and 50 male) pwMS participated (mean age = 38.9 years). The course of the disease was RRMS in 173 patients and mean EDSS was 2.0. 68.5% of the participants were married, 32.5% were employed, and 57.2% had secondary education. The MSSM-R mean score of the study group was 42.6 ± 10.4 (1-81). There was a positive correlation between MSSM-R and MUSIC-cog scores (r = 0.21, p = 0.003). A hierarchical multiple regression revealed that income level (β = 0.196, t = 2.692, p = 0.008) and cognitive performance (β = 0.167, t = 2.063, p = 0.041) together with control variables (gender, age, educational status, employment status, duration of disease, EDSS and fatigue) explained 5.5% of the variance in self-management.Cognitive performance is a predictor of self-management in pwMS. Better self-management behavior is also related with employment and income level in pwMS. Studies evaluating patients' cognitive abilities and evaluating the effectiveness of adapted self-management training programs are needed.

Demonstrate of accidental intravascular injection during lumbar transforaminal anterior epidural steroid injection (TAESI) performed with three-dimensional imaging angiography (3DIA) and fluoroscopy.We assessed 20 (9 males and 11 females) patients (with a total of 40 levels) whose images were received with simultaneously 3DIA and fluoroscopy-guided TAESI between January 2016 and September 2016 as retrospective. Injections were carried out in the lumbar fourth intervertebral space bilaterally and performed in the same way all of the cases.The mean age and body mass index of the patients were 47.9±2.72 years and 26.95±1.21, respectively. There were 10 patients with disc herniation, seven patients with spinal stenosis, and three patients with failed back surgery syndrome. In 3D imaging, vascular escape was detected in the 7 levels (17.5%) which were thought to be no escape in the fluoroscopy imaging.In chronic lumbar radiculopathy patients, intravascular escapes may occur during the fluoroscopic TAESI procedure. To avoid intravascular injections during TAESI procedure, it may be appropriate to use different imaging methods that can give more detailed results such as 3D angiography.

Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive modality, and has a high risk of causing post-ERCP pancreatitis (PEP). Risk factors of PEP have been investigated and conflicting results are present for most risk factors. The aim of this study was to evaluate the risk factors for PEP and to determine whether the risk factors differ due to the ERCP indication.A retrospective study was conducted which included 666 patients with 968 ERCP procedures. Some risk factors were evaluated for PEP, and they were also evaluated separately for patients with bile duct stones and patients who underwent ERCP for other reasons than bile duct stones.In patients with bile duct stones detected on ERCP ; female gender, lower diameter of the common bile duct, placing a biliary plastic stent and not having a cholecystectomy history were risk factors for PEP, whereas in patients without bile duct stones the only risk factor for PEP was not having a prior endoscopic sphincterotomy.Our study revealed that PEP risk factors depend on the indication of ERCP. To the best of our knowledge our study is the first study defining cholecystectomy as a protective factor for PEP in patients with bile duct stones and endoscopic sphincterotomy history as a protective factor for PEP in patients without bile duct stones. Our study also showed that female gender, lower diameter of the common bile duct and placing a plastic biliary stent were risk factors for PEP in patients with bile duct stones.

Background There are reports that acrochordon (skin tag), the most common fibroepithelial tumor of the skin, may be associated with metabolic syndrome components, particularly insulin metabolism disorders. However, to the best of our knowledge, there is no study examining its association with insulin resistance and tissue levels of insulin-like growth factor 1 receptor (IGF-1R) and insulin-like growth factor 2 receptor (IGF-2R). Methods Thirty patients with at least one acrochordon in their body who had no known history of diabetes mellitus and a control group comprised 30 individuals who had no acrochordon or no known history of diabetes mellitus were included. The tissue expression of IGF-1R and IGF-2R were investigated via immunohistochemical assessment in both groups. Results In the group with acrochordon, IGF-1R and IGF-2R expression was found to be significantly higher compared to the control group (p Conclusion These findings support the view that insulin metabolism disorders should be evaluated in patients with acrochordon. Our study indicates that IGF receptors may have an effect on acrochordon pathogenesis and that acrochordon etiology and related conditions can be clarified by detection of parameters that influence receptor levels.

The relationships of Arsenic (As) and selenium (Se) to Alzheimer's Disease (AD) are not clearly known. This case-control observational study aims to investigate the possible relationship of these elements to the diagnosis and pathophysiology of the disease.This case-control observational study was performed using 40 AD patients in different clinical stages and 40 healthy control subjects, living in a similar environment with low As exposure. The levels of As and Se in nail and hair were measured with Inductively Coupled Plasma Mass Spectrometry. The results were analysed with regards to clinical condition, age, disease duration, sex, education, living environment, and the relationship of the two elements using Mann Whitney U test and Spearman Rho or Pearson correlation tests as appropriate.The levels of As and Se were not related to age, disease duration, sex, education, or living environment in the study groups (p 0.05). The levels of As and Se in hair and nail samples of all patients and patient subgroups were higher than those in the healthy subjects (p 0.001). A positive correlation was found between the levels of As and Se in both hair and nail samples only in the patient group (p 0.01).According to the results, As and Se levels probably increase due to some metabolic or genetic factors affecting both of them together. There may be an increase in the unregulated pool (selenomethionine) and a decrease in the regulated pool of Se (selenosycteine) in AD. Our findings need verification and the subject seems to deserve more elaborate evaluations including genetic analyses and analysis of different chemical forms of these elements.

We aimed to evaluate the effects of complex decongestive therapy (CDT) on upper extremity functions, the severity of pain, and quality of life. We also searched the impact of the sociodemographic and clinical characteristics on the improvement in upper extremity functions.A total of 37 women with breast cancer-related lymphedema (BCRL) [age, 53.6 ± 11.2 (28-72)] were included in this study. All patients underwent CDT-phase 1 program, including meticulous skin care, manual lymphatic drainage, remedial exercises, and compression bandages. Arm volume was calculated by a formula for truncated cone using circumferential measurements. A baseline questionnaire, including sociodemographic and clinical properties, was used for each patient. Short Form-36 (SF-36), Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and Visual Analog Scale (VAS) for pain and heaviness were used as clinical assessment scales.The mean of the posttreatment volume of the affected limb was lower compared to pretreatment volume (2741.81 ± 696.85 and 2990.67 ± 745.49, respectively), and the mean percentage change in edema volume was 38.1% ± 26.5%. We observed a statistically significant reduction in pain and heaviness VAS scores and improvement of shoulder mobility among upper extremities with lymphedema (p 0.001) after CDT. The mean of posttreatment DASH score was lower compared to pretreatment score (37.19 ± 16.01, 49.81 ± 18.84, respectively, p 0.001). All subgroups of the SF-36 parameters were increased after the CDT application (p 0.01). Besides being under 65 years old, having a body mass index above 30 and short duration of lymphedema were found to be related to greater improvement in upper extremity functions.CDT provides enhancement of upper extremity functions and quality of life in patients with BCRL. The reduction in lymphedema volume, pain, and heaviness and the improvement in shoulder mobility may be the contributed factors.

Introduction: We aimed to explore the possibility of using body surface area (BSA) as a new anthropometric measurement in evaluation of OSAS. Materials and Methods: Obesity was defined as having a BMI ? 30 kg/m2. BSA were calculated using the Mosteller and Boyd formulas. Totaly 426 (306 male) cases were included in this study. Results: The mean BMI was 33.0 kg/m2. The mean BSA was 2.06 m2 and 2.11 m2 respectively. BMI, AHI, oxygen desaturation, ODI and oxygen saturation were found different between the groups. Both BMI and BSA correlated positively with AHI, oxygen desaturation and ODI and negatively with oxygen saturation. There was no difference between BMI and BSA in mild cases in both gender. However, in moderate and severe cases, BMI and BSA were higher in males. We dedected that BSA and BMI display similar sensitivity and specificity values for the prediction of severe OSAS. Conclusion: To the best of our knowledge, this is the first study to examine the potential association between BSA and the severity of OSAS. As a result, we determined that BSA correlated with polisomnographic parameters as BMI. In severe OSAS BSA can be used as a predictor parameter like BMI. Giriş: Obstrüktif uyku apne sendromu (OSAS) hastalarının değerlendirilmesinde vücut yüzey alanı (VYA)’nın yeni bir antropometrik ölçüm olarak kullanılıp kullanılamayacağını araştırmayı amaçladık. Materyal ve Metod: Vücut kitle indeksinin (VKİ) ? 30 kg/m2 olması obezite olarak kabul edildi. BSA Mosteller ve Boyd formülleri kullanılarak hesaplandı. Bu çalışmaya toplam 426 (306 erkek) olgu dahil edildi. Bulgular: Ortalama VKİ 33.0 kg/m2, VYA sırasıyla 2.06 m2 ve 2.11 m2 idi. VKİ, AHİ, oksijen desatürasyonu, oksijen desatürasyon indeksi (ODİ) ve oksijen satürasyonu gruplar arasında farklı bulundu. Hem VKİ hem de VYA AHI, oksijen desatürasyonu ve ODİ ile pozitif ve oksijen satürasyonuyla negatif korelasyon gösterdi. Her iki cinsiyette de hafif olgularda VKİ ve VYA açısından farklılık yoktu. Ancak orta ve ciddi olgularda erkeklerde VKİ ve VYA daha yüksekti. VYA ve VKİ’nin şiddetli OSAS’ın öngörülmesinde benzer duyarlılık ve özgüllüğü olduğunu belirledik. Sonuç: Bildiğimiz kadarıyla, bu çalışma BSA ile OSAS’ın ciddiyeti arasındaki potansiyel ilişkiyi inceleyen ilk çalışmadır. Sonuç olarak, VYA’nın VKİ’sinde olduğu gibi polisomnografik parametrelerle korele olduğunu belirledik. Ağır OSAS olgularında VYA VKİ gibi belirleyici bir parametre olarak kullanılabilir.

BACKGROUND/AIMS Pancreatic steatosis (PS) is a generally used term to define accumulation of fat in the pancreas. In theory PS may be able to affect the exocrine function of pancreas. In this study we aimed to determine the effect of PS on exocrine pancreas function. MATERIALS AND METHODS Forty-three patients with PS determined by 3 tesla magnetic resonance imaging (MRI) and 48 patients without PS were included in this study. Patients with PS were classified as group 1 and control patients were classified as group 2. Fecal elastase-1 levels were determined. Fecal elastase-1 levels

Savran, Levent/0000-0001-8824-3207 WOS: 000461371500011 PubMed: 30171442 To investigate the effect of photobiomodulation (PBM) and placebo on total amount of substance P in gingival crevicular fluid (GCF) pre- and postoperatively. Twenty-six patients having tooth with symptomatic apical periodontitis were enrolled in this study. GCF was collected preoperatively. The patients were assigned into two groups (n=13), as follows: placebo and PBM. Sampling was repeated 7days after root canal treatment. Two independent samples T test was used for analyzing of the differences between preoperative and postoperative substance P levels in GCF (p=.05). The Pearson correlation analysis was used for determination of correlation among substance P levels and other variables. For placebo group, there is no significant difference between preoperative and postoperative total amounts of substance P level (p=0.553). For PBM group, postoperative total amount of substance P level was significantly higher than those of preoperative level (p=0.005). Within the limitation of the present study, PBM has immunomodulation effect linked to the modulation of the total amount of substance P in the gingival crevicular fluid.

Alisik, Murat/0000-0003-0434-3206; EREL, Ozcan/0000-0002-2996-3236; WOS: 000444369100007 PubMed: 30160158 OBJECTIVES: The aim of the study was to determine dynamic thiol-disulphide homeostasis in patients with ulcerative colitis, compare it with those of healthy control and to investigate the relationship between the severity of the disease and homeostasis METHODS: A total of 78 patients and 58 healthy subjects were included in the study. Serum native thiol, total thiol and disulphide amounts were measured by using a novel automated method. Obtained results were compared and relationships were determined by correlation analysis. RESULTS: Serum native thiol, total thiol, disulphide amounts and disulphide/native thiol percent ratio (index) were significantly lower (p = 0.003 for index ratio and p < 0.001 for other parameters) in patients with ulcerative colitis than in healthy controls. Native thiol, total thiol and disulphide amounts were significantly higher (p < 0.001) in patients with ulcerative colitis in remission than in patients with active ulcerative colitis and near to those of healthy control. There were significant negative correlations between the severity of the disease and thiol-disulphide homeostasis parameters (r = -0.55, p < 0.001 for native thiol; r = -0.64, p < 0.0001 for total thiol; r = -0.65, p < 0.001 for disulphide and r = -0.33, p = 0.011 for index). CONCLUSION: The thiol-disulphide homeostasis was weakened in ulcerative colitis. Strong correlations between the activity of the disease and thiol-disulfide homeostasis indicate that homeostasis may play a role in the pathogenesis of the disease (Tab. 3, Fig. 3, Ref. 30).

WOS: 000433285000010, PubMed ID: 28968197, Once-daily dosing of non-vitamin K antagonist oral anticoagulants (NOACs) may increase patient adherence to treatment but may also be associated with a higher risk of bleeding. In this study, we investigated the adherence to once-or twice-daily dosing of NOACs and the risk of bleeding in nonvalvular atrial fibrillation (NVAF) patients. This multicenter cross-sectional study, conducted between 1 September 2015 and 28 February 2016, included 2214 patients receiving NOACs for at least 3 months, due to NVAF. Patients receiving once-daily or twice-daily NOAC doses were 1: 1 propensity score matched for baseline demographic characteristics and the presence of other diseases. The medication adherence was assessed by the 8-item Morisky Medication Adherence Scale. Risk factors were investigated in relation to minor and major bleeding. The mean age of patients was 71 +/- 10 years, and 53% of the patients were women. The medication adherence was lower in patients receiving twice-daily NOAC doses compared to once-daily-dose group (47% versus 53%, p = 0.001), and there was no difference between the groups in terms of minor (15% versus 16%, p = 0.292) and major bleeding (3% versus 3%, p = 0.796). Independent risk factors for bleeding were non-adherence to medication (OR: 1.62, 95% CI: 1.23-2.14, p = 0.001), presence of 3 or more other diseases (OR: 10.3, 95% CI: 5.3-20.3, p < 0.001), and HAS-BLED (Hypertension, Abnormal renal and liver function, Stroke, Bleeding, Labile INR, Elderly, Drugs or alcohol) score (OR: 4.84, 95% CI: 4.04-5.8, p < 0.001). In summary, the once-daily dose of NOACs was associated with increased patient adherence to medication, while it was not associated with bleeding complications.

The mechanisms underlying acute pancreatitis have not been well elucidated. Over the last 20 years, there has been increasing awareness regarding the role played by oxidative stress in acute pancreatitis, but it is less well defined in human clinical trials. The aim of this study was to identify the relationship between antioxidants and acute pancreatitis.We performed a cross-sectional trial on patients with mild acute pancreatitis. The study population consisted of 53 patients with mild acute pancreatitis and 55 healthy controls. Serum paraoxonase, arylesterase activity, total antioxidant status, total oxidant status and thiol levels were measured, and oxidative stress index was calculated.Paraoxonase, arylesterase activity, thiol and total antioxidant status levels were significantly lower in the acute pancreatitis group than in the control group (p = .024, p .001, p .001, p = .010, respectively). Oxidative stress index and total oxidant status levels were higher in the acute pancreatitis group than in the control group, but the difference was not statistically significant (p = .135, p = .253, respectively).This study demonstrates that decreased antioxidant levels are associated with mild acute pancreatitis. No association was observed between mild acute pancreatitis and total oxidant status.

WOS: 000411827200025, PubMed ID: 28961828, Background: Reed-Sternberg cells of classical Hodgkin's lymphoma (cHL) are characterized by genetic alterations at the 9p24.1 locus, leading to over-expression of programmed death-ligand 1 and 2. In a phase 1b study, nivolumab, a PD-1-blocking antibody, produced a high response in patients with relapsed or refractory cHL, with an acceptable safety profile. Patients and methods: We present a retrospective analysis of 82 patients (median age: 30 years; range: 18-75) with relapsed/refractory HL treated with nivolumab in a named patient program from 24 centers throughout Turkey. The median follow-up was 7 months, and the patients had a median of 5 (2-11) previous lines of therapy. Fifty-seven (70%) and 63 (77%) had been treated by stem-cell transplantation and brentuximab vedotin, respectively. Results: Among 75 patients evaluated after 12 weeks of nivolumab treatment, the objective response rate was 64%, with 16 complete responses (CR; 22%); after 16 weeks, it was 60%, with 16 (26%) patients achieving CR. Twenty patients underwent subsequent transplantation. Among 11 patients receiving allogeneic stem-cell transplantation, 5 had CR at the time of transplantation and are currently alive with ongoing response. At the time of analysis, 41 patients remained on nivolumab treatment. Among the patients who discontinued nivolumab, the main reason was disease progression (n = 19). The safety profile was acceptable, with only four patients requiring cessation of nivolumab due to serious adverse events (autoimmune encephalitis, pulmonary adverse event, and two cases of graft-versus-host disease aggravation). The 6-month overall and progression-free survival rates were 91.2% (95% confidence interval: 0.83-0.96) and 77.3% (0.66-0.85), respectively. Ten patients died during the follow-up; one of these was judged to be treatment-related. Conclusions: Nivolumab represents a novel option for patients with cHL refractory to brentuximab vedotin, and may serve as a bridge to transplantation; however, it may be associated with increased toxicity.

Background/aims To evaluate the incidence of insulin resistance and metabolic syndrome (MetS) in patients with glycogenic acanthosis (GA). Materials and methods Thirty patients with GA, detected upon endoscopy, and 30 age- and sex-matched control patients without GA were included in this case-control study. Patients with GA were considered group 1 and control group was considered group 2. Anthropometric measurements [height, weight, and waist circumference (WC)], biochemical parameters [fasting plasma glucose (FPG), triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL)], and serum fasting insulin levels were evaluated. Insulin resistance (IR) was estimated by the homeostatic model assessment of IR. MetS was diagnosed using the criteria of the National Cholesterol Education Program Adult Treatment Panel III. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated to evaluate associations with GA. Results There were no differences in terms of FPG, triglyceride, HDL, and LDL between groups (p-values 0.118, 0.114, 0.192, 0.086, respectively). WC was significantly higher in group 1 than in group 2 (103.77 vs 97.03, p=0.032). The number of patients with IR and MetS were significantly higher in group 1 than in group 2 (53.3% vs 13.3%, p=0.003 and 53.3% vs 23.3%, p=0.034). ORs [95% CI] of WC, IR, and MetS for GA were 0.68 [0.17-2.62], 7.12 [1.89-26.72], and 4.11 [1.04-16.21], respectively. Conclusion These findings showed that IR and MetS were significantly associated with the presence of GA.

Objective The pathogenesis of medication-related osteonecrosis of jaw (MRONJ) is poorly understood. The aim of this prospective study was to determine the effect of chronic dental inflammation on the development of Stage 0 MRONJ based on histopathological findings. Methods The study involved patients with a history of bisphosphonate use and an indication for tooth extraction. Before surgery, C-terminal telopeptide test (CTX) values were collected from all patients. All tooth extractions were performed according to a determined protocol. To detect whether any medication-related osteonecrotic changes were present in the non-exposed bone, biopsy samples were taken from the alveolar bone. Results A total of 50 patients were included in the study (39 women and 11 men). The patients were mean age of 57.4 ± 12.1 years. In total, 74 teeth were extracted (29 maxillary and 45 mandibular). Histologic examination of three patients (6%) revealed Stage 0 MRONJ. Postoperatively, the complete mucosal healing success rate was 96%. MRONJ risk was not significantly correlated with low CTX value (p = 0.285). Conclusions Chronic inflammation may contribute to Stage 0 MRONJ; however, its role may not be sufficient alone for its development. Application of a predetermined protocol for dentoalveolar processes will help to prevent MRONJ development.

In order to reveal the underlying retinal pathology leading to dysfunction in vigabatrin-exposed patients, we aimed to evaluate the inner retinal layers encompassing ganglion cell complex (GCC) layer and inner plexiform layer with new generation optic coherence tomography (OCT). Fourteen patients with epilepsy and exposure to vigabatrin and 12 clinically normal individuals, constituting the control group, were included. Retinal images were obtained using spectral-domain OCT (Optovue RTVue Fourier domain). Nasal and superior quadrants of retinal nerve fiber layer (RNFL) were found to be significantly lower in the patient group compared to the controls (p 0.01). No significant difference was shown in the thickness of GCC layer (p 0.05). Foveal thickness was significantly higher in the patient group (p: 0.006), but no significant difference was found in perifoveal and parafoveal regions between groups (p 0.05). The thickness of RNFL was found to be lower in vigabatrin-exposed patients without any reduction in GCC layer in the macular region. However, foveal thickness was found to be significantly higher compared to perifoveal and parafoveal macular regions in vigabatrin-exposed patients. In conclusion, OCT revealed reduced thickness of RNFL without any reduction in ganglion cell layer in our study. The objective quantitative assessment of OCT is a practical noninvasive method and it can have role in future monitoring of these patients.

Metals, especially transition metals, seem to be important in the pathogenesis of Alzheimer disease. This study aims to determine the relationship of trace metal elements to the pathogenesis and/or course of Alzheimer Disease in terms of clinical severity.The hair and nail trace metal levels of 62 Alzheimer Disease patients at different clinical stages (21 mild, 20 moderate, 21 severe) and 60 healthy control subjects were measured by using inductively coupled plasma-mass spectrometry. The statistical comparisons were performed with regards to the study groups, clinical stages, disease duration and age.The patient and control groups were significantly different from each other in regards to Mn, Fe, Cu, Cd, Hg (p0.001), Zn (p0.01) in nail concentrations and, Na, Al, Pb, Co (p0.001), Fe, Mn (p=0.001), Hg, Cu, Cd, K in hair concentrations (p0.01). No difference was detected in the levels of Mg and Ca. Nail Na level showed differences among different clinical stages of the disease (p0.01). In comparing the mild degree Alzheimer patients to the control group; significant differences were detected in nail Mn, Fe, Cu, Co (p0.001), Hg, Zn (p0.01) and, hair Pb, Al (p0.001), Na, K levels (p0.01).Our results have shown that transition and posttransition metals are especially important metals for the disease process. The relation of nail Na level with clinical stages of AD is an interesting new finding, making someone to think that alkali metals may be important in the progression of the disease.

Savran, Levent/0000-0001-8824-3207 WOS: 000467760500026 PubMed: 30892373 The aim of this study was to investigate the effect of a placebo, intracanal diode laser application, and low-level laser therapy (LLLT) on the change of the total amount of calcitonin gene-related peptide (CGRP) in the gingival crevicular fluid (GCF) (split-mouth study design). GCF sampling was performed on a contralateral tooth and experimental tooth (root canal-treated tooth) of thirty-nine patients. The patients were divided into three groups (n = 13), as follows: placebo (mock laser application), intracanal laser application, and LLLT. GCF sampling was repeated at the same sites (experimental and control teeth) one week after root canal treatment. The data were analyzed using the Pearson's correlation analysis and the independent-samples t-tests (p=0.05). In the placebo group, the total CGRP level changes in the GCF before and after treatment was significantly higher for experimental teeth than for control teeth (p 0.05). Intracanal laser application and low-level laser therapy have immunomodulation effects linked to the modulation of the total amount of CGRP in the GCF.

WOS: 000469036700030 PubMed ID: 30940426 Objective: To evaluate whether combining fluidotherapy to conventional rehabilitation program provides additional improvements on pain severity, upper extremity functions, and edema volume in patients with poststroke complex regional pain syndrome (CRPS). Design: Randomized controlled trial. Setting: Training and research hospital. Participants: Thirty hemiplegic patients with subacute stage CRPS type-1 of the upper extremity. Interventions: The patients randomly divided into 2 groups. Both groups received a 3 week conventional rehabilitation program (5 days/week, 2-4 hours/day). Experimental group received 15 sessions additional fluidotherapy application to the affected upper extremity (40 degrees C, 20 minutes in continuous mode, 5 sessions/week). Main Outcome Measures: We evaluated the distal upper arm edema with a volumeter. Other used clinical assessment scales were Brunnstrom recovery stages of the arm and hand for motor recovery, motor items of the functional independence measure for functional status, visual analog scale for pain severity, and the painDETECT questionnaire for presence and the severity of neuropathic pain. Results: The mean age of the participants was 64.3 +/- 11.66 (28-84). At the post-treatment evaluation, significant improvements were revealed regarding to the edema volume, pain visual analog scale, painDETECT and functional independence measure scores, and the Brunnstrom stages of upper extremity and hand in both groups (P

Background: Obstructive sleep apnea syndrome (OSAS) is an independent risk factor for cardiovascular disease (CVD). Although monocyte to high-density lipoprotein cholesterol ratio (MHR) is increasingly being implicated in cardiovascular morbidity and mortality, no study has attempted to determine the role of MHR in cardiovascular morbidity of patients with OSAS. We aimed to investigate the association between MHR and CVD in patients with OSAS and the relationship between severity of OSAS, polysomnographic parameters, and MHR. Methods: In this cohort study, patients who had undergone a full-night polysomnography for the diagnosis of OSAS were recruited. Included patients were grouped according to the apnea–hypopnea index (AHI) as mild (5-15), moderate (15-30), and severe (>30) OSAS. Patients with AHI < 5 served as the control group. The presence of heart failure, coronary artery disease, or arrhythmia was defined as CVD. Results: A total of 1050 patients were included (131 controls, 222 mild, 228 moderate, and 469 severe OSAS). The severe group had higher MHR compared with the control and other OSAS groups (9.99, 12.11, 13.65, and 20.67 in control, mild, moderate, and severe OSAS groups, respectively, P < .001). The MHRs were significantly correlated with AHI, oxygen desaturation index, and minimum O2 saturation values ( P < .001). Values of MHR were significantly higher in patients with CVD compared with those without ( P < .001). Multiple regression analysis demonstrated that MHR is an independent predictor of CVD. Conclusion: The MHR is strongly associated with CVD and the severity of OSAS and might be used as a biomarker to predict CVD in patients with OSAS.

To elucidate the effects of Kinesio Taping (KT) in addition to neurodevelopmental therapy (NDT) on posture and sitting, and to compare the effects of KT and neuromuscular electrical stimulation (NMES).Seventy-five children were randomized into control, KT, and NMES groups. NDT was applied to all children 4 times a week for 4 weeks. In addition, KT and NMES were applied to KT and NMES groups, respectively. Sitting subset of Gross Motor Function Measure (GMFM) and kyphosis levels of the groups were analyzed by two way mixed ANOVA.GMFM and kyphosis values improved significantly in all groups (all p 0.01), yet change levels were more prominent in the KT and NMES groups than the control group. Moreover, NMES group showed better improvement.KT or NMES application for four weeks in addition to NDT is effective on improving kyphosis and sitting. Besides, NMES is more effective than KT.

Objective To evaluate the short-term effects of horseback riding therapy in addition to a conventional rehabilitation program in children with cerebral palsy. Methods Nine children receiving horseback riding therapy in addition to conventional rehabilitation (Group 1) and seven children receiving conventional rehabilitation alone (Group 2) were assessed at baseline and 5 weeks later. Assessed were: modified functional reach test (MFRT), hip abduction angle, the Ashworth Scale for hip adductor muscle spasticity, knee distance test, and the Gross Motor Function Classification System (GMFCS). Results The percentage change in hip adductor spasticity on the Ashworth Scale was 22% in Group 1 and 0% in Group 2 (significant difference; p = 0.016). Comparison of changes on the MFRT, GMFCS, knee distance test and hip abduction angle showed that the differences between Groups 1 and 2 were not significant. Conclusions In these children, horseback riding therapy in addition to conventional rehabilitation resulted in significant improvement in adductor spasticity on short-term follow-up.

WOS: 000484118100022 PubMed ID: 30664229 Background: Pneumatisation of the inferior turbinate (PIT) is a rare abnormality of the paranasal sinus. It is very difficult to differentiate from the hypertrophia of the inferior turbinate clinically. Thus, it is important to be considered, especially in cases with no response to medical treatments. We aimed to investigate the presence and the frequency of PIT by computed tomography (CT). Materials and methods: A total of 2905 cases (1381 female, 1524 male) with an age range between 16 and 84 were included. Results: The pneumatisation of the inferior turbinate was observed in 1.72% of the cases with a percentage of 1.88% in women and 1.57% in men. In PIT (+) cases the bilaterality was found in 54% of them. According to the subtypes, 70% was lamellar, 28% was bullous and 2% was extensive. No statistically significant difference was found for age distribution. The most commonly associated variations were the pneumatisation of the middle and upper turbinate and the septal deviation. Conclusions: The pneumatisation of the inferior turbinate is a rare variation with a similar frequency among men and women. It is diagnosed by CT and when symptomatic the optimal treatment is surgery.

Nerve injections have been used for the acute and preventive treatment of migraine in recent decades. Most of these injections focused on greater occipital nerve (GON) blockade. However, few studies were placebo controlled, and only a few of them investigated GON and supraorbital nerve (SON) blockade together. This study aimed to evaluate the efficacy of GON and SON blockade with local anesthetics for the preventive treatment of migraine without aura.Eighty-seven patients diagnosed with migraine without aura were included in the study. Patients were divided randomly. One group was injected with 1% lidocaine, the other group was injected with 0.9% saline. GON and SON injections were done bilaterally. The injections were repeated weekly for 3 weeks. Patients were followed up for 2 months to assess clinical response.Seventy-one patients completed the study. After 2 months, the number of headache days decreased significantly from 12.8 ± 10.9 to 5.3 ± 7.4, and VAS decreased from 8.3 ± 1.0 to 5.5 ± 1.9 in the blockade group. The number of headache days decreased from 12.4 ± 10.3 to 7.5 ± 7.2 and VAS decreased from 8.2 ± 1.1 to 7.4 ± 1.3 in the placebo group. Response was seen in 65.1% of the patients in the blockade group (65.4% for episodic migraine, 64.7% for chronic migraine) and 28.6% of the patients in the placebo group. The difference was significant.The results suggest that GON and SON blockade with lidocaine was more effective than the placebo in the prophylactic treatment of both episodic and chronic migraine.

There are only a few studies in the literature investigating the effects of gestational age on developmental dysplasia of the hip. The aim of this study was to investigate the effects of gestational age on hip ultrasound findings in the early neonatal period in preterm newborns born between 30th and 36th weeks of gestational age. Between January 2008 and December 2013, a total of 788 hips of 394 premature newborns with a gestational age of up to 36th weeks who underwent hip ultrasonography in the first week of their life were retrospectively examined. The distribution of roof angles and hip types in terms of sexes was compared between groups. Birth weight, birth height, a, and beta angles were analyzed in terms of the gestational age. The mean gestational age was 33.07 weeks (SD 2.09; between 30th and 36th). Six hundred and seven hips were classified as type I, 154 as type IIa, 21 as type IIc, and 6 as type III. In the 30th week, type IIc hips in females and type III hips in males were statistically significantly higher (P=0.001). In the 34th week, type IIc hips in males were statistically significantly higher than the females (P=0.013). In the 35th week, type IIa hips in females hips were statistically significantly higher than the males (P=0.008). Among all preterm infants, type IIc hips were more common in the 30th, 31st, 32nd, and 34th weeks, whereas type III hips were statistically significantly more common in the 30th week (P=0.0001). The 30th, 31st, 32nd, and 34th weeks of age are gestational ages that should be considered in terms of dysplastic and subluxed hips in premature newborns.

The aim of this study was to evaluate the association between bone mineral density (BMD) and 25-hydroxyvitamin D [25(OH) D] levels in patients with obstructive sleep apnea syndrome (OSAS). This study was designed as a cross-sectional and observational study. Patients who underwent polysomnography evaluation were classified as normal, mild, moderate, severe, or position-dependent OSAS, and OSAS + obesity hypoventilation syndrome (OHS). BMD was measured with the dual-energy X-ray absorptiometry method at the femur and lumbar spine. The chemiluminescence microparticle immunoassay was used for the measurement of 25(OH) D levels. A total of 126 patients (73 males, 53 females) with a mean age of 48.55 ± 11.8 years were included. Body mass index was significantly higher in the OSAS + OHS group than in the other groups (p0.01). There was no statistically significant difference between the groups in terms of total BMD, T-scores and Z-scores of the lumbar spine, femural neck, and total femur (p0.05 for all). Post hoc analyses showed that OSAS + OHS subgroup had lower level of 25(OH) D compared to the normal subjects (p = 0.006). Yet no significant difference was observed between the other OSAS groups. No significant correlation was observed between the apnea hypopnea index, the Epworth Sleepiness Scale scores, desaturation index, and BMD parameters (all for p0.05). While 25(OH) D levels were lower in OSAS + OHS patients, there was no statistically significant relationship between OSAS and BMD values.

BACKGROUND AND AIM In patients diagnosed with coronary artery disease (CAD), we aimed to determine the characteristics and risk factors of co-occurring musculoskeletal pain and examine its effects on functional capacity, psychological status and health-related quality of life. PATIENTS AND METHODS A total of 100 patients with (n= 50) and without (n= 50) musculoskeletal pain were enrolled. All patients were assessed on sociodemographic and clinical properties. The Duke Activity Status Index (DASI), the Hospital Anxiety and Depression Scale (HADS) and the Short Form-36 (SF-36) were applied as clinical assessment scales. RESULTS Patients with musculoskeletal pain were mostly female, and had a lower education level and annual income. The pain was mostly nociceptive, intermittent, sharp/stabbing in character, and located in the chest and spine. Having musculoskeletal pain resulted in lower levels on the DASI and all subgroups of the SF-36, and higher levels on the HADS. Female gender, lower education level and severity of emotional distress proved to be independent risk factors for the development of musculoskeletal pain. CONCLUSIONS In CAD, the co-occurrence of musculoskeletal pain leads to a further decrease in health-related quality of life and functional status, and increased severity of anxiety and depression. This stresses the importance of the detection and optimal treatment of musculoskeletal pain in patients diagnosed with CAD.

BACKGROUND/AIMS The dynamic thiol/disulfide homeostasis plays pivotal roles in many physiological mechanisms in an organism. We aimed to investigate whether dynamic thiol/disulfide homeostasis changes among patients with acute pancreatitis. MATERIALS AND METHODS This prospective trial contained 45 patients with acute pancreatitis and 45 sex-and age-matched healthy volunteers as control group. Thiol/disulfide homeostasis parameters were measured by a novel and automated assay, and detected results were compared between the two groups. RESULTS Disulfide/total thiol percent ratio and disulfide/native thiol percent ratios were significantly higher in acute pancreatitis group; besides the native thiol, total thiol levels and native thiol/total thiol percent ratios were significantly lower (for all p < 0.001). CONCLUSION The thiol/disulfide homeostasis is impaired in acute pancreatitis with a shift toward the oxidative status, and this deficiency might be a pathogenic factor in acute pancreatitis. The correction of this thiol/disulfide imbalance may be a new target in the management of acute pancreatitis.

Objectives We aimed to determine whether multiple sclerosis (MS) and methylprednisolone and disease-modifying drugs have an effect on menopausal age. Methods A total of 86 patients and 98 healthy subjects were included in this study. The natural menopausal age of the patients and healthy subjects were compared. The cumulative dosages of methylprednisolone, beta interferons (IFNβs), and glatiramer acetate were calculated. The effects of the Expanded Disability Status Scale (EDSS), duration of the disease, and cumulative dosage of medications on menopausal age were evaluated. Results The patients’ mean menopausal age was 45.3 ± 4.8 years and healthy subjects’ menopausal age was 46.8 ± 4.3 years, with no significant difference between the two groups. The cumulative dosage of methylprednisolone showed an effect on menopausal age. There was a significant inverse correlation between menopausal age and dosage of IFNβ-1b, while the disease duration and EDSS score showed no correlation with menopausal age. Conclusions We conclude that menopausal age is not affected by MS. However, long-term methylprednisolone and IFNβ-1b treatments may change menopausal age in a dose-dependent manner.

Introduction: Obstructive sleep apnea (OSA) syndrome is closely associated with cardiovascular and metabolic disorders. Recent studies reported that osteoarthritis (OA) is associated with cardiovascular disease as well as inflammation defined as “metabolic disorder”. Due to the strong association of metabolic disorders with both OA and OSA, we aimed to investigate the association between severity of OSA and osteoarthritis grade based on X-Ray. Materials and Methods: Patients who underwent polysomnography due to suspicion of OSA were recruited in a cross-sectional study. Included patients were grouped according to apnea-hypopnea index (AHI) as mild (AHI between 5 and 14.9), moderately (AHI between 15 and 29.9), and severe OSA (AHI ? 30). Patients with AHI < 5 served as the control group. Kellgren-Lawrence scoring system was used to express OA severity, which was graded as Grade 0, 1, 2, 3 and 4. Results: One hundred twenty patients were enrolled into the study. Mean age was 52.4 ± 11.5 years and 56% (68/120) of the patients were male. A strong correlation was present between severity of OSA and severity of OA. Among those with Grade 4 OA group (33 patients), all patients had severe OSA and this association was independent from body-mass index. In the Grade 1 OA group, none of the patients had severe OSA (p< 0.05). A positive correlation was also seen between severity of OSA, OA and hs-CRP. Conclusion: There is a strong association between OSA and OA. OSA might be a novel risk factor for the development OA. Further studies should evaluate the effect of OSA treatment on OA. Giriş: Obstrüktif uyku apne ile kardiyovasküler hastalıklar ve metabolik bozukluklar arasında sıkı ilişki vardır. Yapılan araştırmalar osteoartrit ile kardiyovasküler hastalık ve inflamasyon arasında da ilişki olduğunu göstermiştir. Bu çalışmada direkt grafi ile sınıflandırılmış osteoartrit ile obstrüktif uyku apnenin ağırlığı arasındaki ilişki araştırılmıştır. Materyal ve Metod: Bu kesitsel çalışmaya obstrüktif uyku apne şüphesi ile polisomnografi yapılan hastalar dahil edildi. Apne hipopne indeksi (AHİ)’ne göre hastalar hafif (AHİ= 5-14.9), orta (AHİ= 15-29.9), ağır (AHİ ? 30) ve kontrol (AHİ < 5) grubu olarak sınıflandırıldı. Osteoartrit ağırlığı Kellgren-Lawrence skorlama sitemi kullanılarak evre 1, 2, 3 ve 4 olarak sınıflandırıldı. Gereç ve Yöntem: Çalışmaya 120 hasta dahil edildi. Hastaların ortalama yaşı 52.4 ± 11.5 yıl olup; hastaların %56 (68/120)’sı erkek olarak tespit edildi. Obstrüktif uyku apnenin ciddiyeti ile osteoartritin ciddiyeti arasında sıkı bir ilişki saptandı. Ağır osteoartriti (evre 4) olan tüm hastaların (33 hasta) ağır obstrüktif uyku apne hastalığı olduğu ve bu ilişkinin beden kitle indeksinden bağımsız olduğu tespit edildi. Hafif evre osteoartrit olan hastaların hiçbirinde obstrüktif uyku apne hastalığı olmadığı saptandı (p< 0.05). Osteoartrit, obstrüktif uyku apne hastalığı ve C-reaktif protein (CRP) arasında sıkı ilişki gözlendi. Bulgular: Obstrüktif uyku apne osteoartrit gelişmesi için bir risk faktörü olabilir. Obstrüktik uyku apne hastalığı tedavisinin osteoartrit üzerine etkisi ile ilgili yeni çalışmalara ihtiyaç vardır.

Background Odontogenic keratocysts have been reported with high recurrence rates in the literature so various treatment modalities from simple enucleation to resection have been performed to achieve the cure. The purpose of this retrospective study was to investigate the recurrence rate of odontogenic keratocysts (OKCs) treated by enucleation and peripheral ostectomy. Material and Methods An electronic search of the database of the Hacettepe University, Faculty of Medicine, Department of Pathology, was undertaken to identify patients histologically diagnosed with OKCs treated at Department of Oral and Maxillofacial Surgery between 2001 and 2015. Results In total, 81 patients were studied. The mean age at the time of diagnosis was 42 years, and the male:female ratio was 1:0.7. OKCs were located primarily in the posterior mandibular region (41%). Twenty-seven patients were re-examined to determine the recurrence rate. The mean follow-up period was 5 years (range, 1–12 years). The recurrence rate was 14.8%. The relationship between location of the lesion and recurrence was not statistically significant (p = 0.559). There was also no statistically significant relation between the recurrence rate and treatment option of teeth involved in the lesion (p = 0.579). Conclusions The authors conclude that treatment of OKCs by enucleation with peripheral ostectomy is associated with minimal morbidity and is preferred over other aggressive treatment modalities. Meticulous radiographic examination and careful surgical resection may decrease the recurrence rate of OKCs. Key words:Odontogenic keratocyst, recurrence rate, enucleation, enucleation plus peripheral ostectomy.

Obstructive sleep apnea syndrome (OSAS) might be a risk factor for the development of eye disorders. The aim of the study was to evaluate the effect of OSAS on central corneal thickness (CCT). A total of 195 patients were enrolled in the study, and underwent polysomnography. Patients were divided according to their apnea-hypopnea index (AHI) scores into control group (AHI 5), mild (AHI, 5-15), moderate (AHI, 15-30), and severe OSAS (AHI 30) groups. In ophthalmological examinations, CCT, auto refractometer measurement, tear break-up time, and Schrimer's test results were evaluated. Central corneal thickness was significantly decreased in patients with OSAS compared to the control group (542.14 ± 31.21 vs. 569.92 ± 13.46, p 0.001). As the severity of OSAS increased, CCT decreased (mild OSAS = 567.48 ± 23 mm, moderate OSAS = 530.21 ± 30.2 mm, and severe OSAS = 557.97 ± 16.52 mm, respectively, p 0.001). The mean values of auto refractometer, tear break-up time, and Schrimer's test were similar between the groups (p 0.05). CCT was negatively correlated with AHI, oxygen desaturation index, desaturation percentages, and positively correlated with minimum oxygen saturation values (p 0.05). This study showed that central corneal thickness is inversely correlated with the severity of OSAS. OSAS affects all organ systems particularly cardiovascular and neurological mechanisms. Further studies are warranted to evaluate the effect of OSAS treatment on CCT.

A novel member of the interleukin (IL)-12 family, IL-35 is an important inhibitory cytokine released by regulatory T cells. The aim of this study is to evaluate gingival crevicular fluid (GCF), saliva, and plasma levels of IL-35 in periodontal disease and health.Samples of GCF, whole saliva, and plasma were obtained from systemically healthy, non-smoking individuals with gingivitis (n = 20) or chronic periodontitis (CP) (n = 20) and periodontally healthy individuals (n = 20). Full-mouth clinical periodontal measurements, including probing depth (PD), bleeding on probing, gingival index, and plaque index (PI), were also recorded. Enzyme-linked immunosorbent assay was used to determine IL-35 levels in the samples. Data were tested statistically by analysis of variance and Pearson rank correlation test.All clinical parameters were significantly higher in the CP group than the healthy and gingivitis groups (P0.001). The GCF total amount of IL-35 was significantly higher in the CP group than the other groups (P = 0.04), whereas the GCF concentration of IL-35 was significantly higher in the healthy group than the other groups (P = 0.002). There were significant differences among the study groups in terms of salivary IL-35 level (P0.001), with the highest level observed in the healthy group and the lowest in the CP group. There was no statistical difference between groups in plasma levels of IL-35 (P0.05). There was a positive correlation between GCF total amount of IL-35 and PD (r = 0.338, P = 0.03) and PI (r = 0.374, P = 0.005) parameters.IL-35 could have an important role in suppressing periodontal inflammation and maintaining periodontal health. Additional studies are required to evaluate its role in periodontal diseases.

The aim of this study was to evaluate and compare the dimensional changes in maxillary extraction sockets that have healed spontaneously and those treated with free gingival grafts. Ten subjects with at least two maxillary anterior teeth scheduled for extraction were selected for this study. Two maxillary teeth were allocated randomly to either the test group or the control group. In the test group, the extraction socket was covered with a free gingival graft harvested from the palate, while in the control group the sockets healed spontaneously. Cone beam computed tomography (CBCT) scans were taken on the day of extraction and at 3 months postoperative. Soft tissue healing of the extraction sockets was assessed visually by clinical inspection. Hard tissue measurements were obtained from the CBCT scans. After 3 months of healing, the control sockets had lost height in the buccal and lingual crestal bones (-1.03 and -0.56mm, respectively); however, the height in the buccal and lingual crestal bones was preserved at the test sites (+0.06 and +0.25mm, respectively). This difference between the two groups was statistically significant (P0.05). In contrast, both the control and test groups lost width in the buccal and lingual crestal bones; the difference between the control and test groups was not statistically significant (P0.05). The authors propose that covering the orifice of the extraction socket with a free gingival graft can result in preservation of the alveolar bone height.

Aim: To define the prevalence of polyautoimmunity (PAI) among celiac disease (CD) patients and to compare clinical and laboratory features of CD patients with or without PAI in order to determine the risk factors for PAI in CD. Material and Method: Patients diagnosed with CD in our clinic between 2007 and 2014 with at least 1 year of follow-up were retrospectively evaluated. Totally 145 patients were included in the study. Information on patient demographics and laboratory data were obtained from patient records. The study participants were divided into 2 groups. Group 1 was the CD-alone group consisting of patients without any other autoimmune diseases (AIDs), while group 2 was the PAI group consisting of patients with accompanying one or more AIDs. Results: The mean age of 145 CD patients (106 female and 39 male) included in the study was 37.2 ± 12.3 years. Of the 145 patients included, 48 (33.1%) were in the PAI group. When two groups were compared with each other in terms of the demographic features and laboratory data, the following were identified as risk factors for PAI: female gender, family history for AIDs, antigliadin IgG positivity, vitamin D deficiency, antinuclear antibody positivity ≥1/80 titer and having any musculoskeletal disease. Conclusion: To the best of our knowledge, this is one of the largest studies in the literature on CD patients for the PAI prevalence and related risk factors. Identification of the risk factors in early stages is important to explore PAI among CD patients. Larger, prospective studies are warranted about the risk factors and autoimmune characteristics of CD.
