Objective: Nasal airway obstruction caused by inferior turbinate hypertrophy is the most troublesome symptom for patients with allergic rhinitis. The aim of this study was to determine any correlation between different nasal obstruction measurements in children with allergic rhinitis., Material and Methods: Nasal airway obstruction was assessed with Sonoelastography, Turkish version of the Nose Obstruction Symptom Evaluation scale, Rhinoconjunctivitis Total Symptom Score and visual analog scale methods in children with allergic rhinitis and the results were compared with a healthy control group., Results: Evaluation was made of a total of 68 patients (40 boys and 28 girls [male: female ratio, 1.42]) with a mean age of 13.35±3.35 (range, 7-18) years. The Rhinoconjunctivitis Total Symptom Score, visual analog scale, and Turkish version of the Nose Obstruction Symptom Evaluation scale scores were significantly higher in the AR group than in the control group (p=0.001, p=0.001, p=0.001, respectively). The sonoelastography scores were significantly higher in the AR group than in the control group (p=0.001). Although a positive significant correlation was determined between Rhinoconjunctivitis Total Symptom Score, visual analog scale, and Turkish version of the Nose Obstruction Symptom Evaluation scale scores in terms of AR severity, no relationship was found with the sonoelastography scores (p=0.022, p=0.009, p=0.001, and p=0.0751, respectively)., Conclusion: The Turkish version of the Nose Obstruction Symptom Evaluation scale and sonoelastography can be used to evaluate nasal obstruction due to inferior turbinate hypertrophy in children with allergic rhinitis., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (Copyright © 2021 Turkish Pediatric Association.)

Background: Fine-needle aspiration cytology (FNAC) is a noninvasive, safe, cost-effective, diagnostic procedure for the evaluation of salivary gland lesions and the selection of patients for surgery. The aim of this study was to analyze the risk of malignancy (ROM) according to the Milan reporting system of salivary gland FNA specimens using a liquid-based cytology (LBC) technique., Methods: The cytological diagnosis of 459 cases between 2014 and 2017 was revised according to the Milan reporting system. The FNAC results of 129 cases with a histological diagnosis were compared with respect to the final diagnosis. The ROM for each category calculated., Results: The ROM was high in the indeterminate and malignant categories, while the ROM in the benign neoplasm category was low. Sensitivity and specificity analyzed in two different ways were 95.1% and 88.8%, 81%, and 77.7%, respectively., Conclusions: When salivary gland lesions are evaluated together with clinical and radiological data, the LBC technique can be applied to salivary gland specimens based on the high diagnostic sensitivity and specificity in liquid-based samples reported according to the Milan system., (© 2019 Wiley Periodicals, Inc.)

Objective: In this study, we aimed to assess renal outcomes of delayed diagnosis of dilating primary vesicoureteral reflux (VUR) following recurrent febrile urinary tract infections (fUTIs) and its diagnostic imaging procedures., Material and Methods: The medical records of patients who underwent ultrasonography (US), non- acute dimercaptosuccinic acid (Tc-99mDMSA) scintigraphy and voiding cystourethrography (VCUG), and who were older than 2 years at the time of VUR diagnosis were retrospectively reviewed., Results: A total of 32 children (female, n=27: 84.4%) with a mean age of 7.67±3.34 years at the time of diagnosis of VUR were included in the study. Grade III, IV, V VUR were found in 22%, 69%, and 9% of the patients, respectively. At the time of VUR diagnosis, abnormal US findings were detected in 75% of the cases. Tc-99mDMSA detected abnormalities in 83.9% (7 with a single scar, 7 with multiple lesions, 12 with reduced kidney function) of the patients. Estimated glomerular filtration rate of 3 patients with bilateral grade IV VUR was <75 mL/min/1.73 m 2 . In 5 patients (16%), VUR could not be predicted by US+DMSA scintigraphy (Grade IV VUR in 3 and Grade III in 2 cases ). The sensitivity in predicting VUR was 75.00% (95% CI: 56.60-88.54) and 83.87% (95% CI: 66.27-94.55), respectively, for US alone and combined US+DMSA., Conclusion: VCUG should be performed routinely in addition to US and non-acute DMSA in all children referred with recurrent fUTIs. Awareness of childhood UTI in public and healthcare personnels should be increased in order to refer these patients at a early stage to pediatric urology and nephrology units.

Purpose: To evaluate the effect of weight loss on the retrobulbar hemodynamics in patients who had undergone bariatric surgery for obesity using color Doppler ultrasound (CDU) and to evaluate correlations with intraocular pressure (IOP) changes measured using Goldman applanation tonometry., Methods: Thirty-two patients were included in this prospective study. Body mass index (BMI), IOP measurements, and retrobulbar CDU examination were performed on all individuals 6 months before and after bariatric surgery., Results: The preoperative mean BMI value was 48.8 ± 2.27 kg/m 2 , and mean IOP value was 18.2 ± 2.06 mmHg. At 6 months postoperatively, mean BMI and IOP were 36.28 ± 5.41 kg/m 2 and 16.1 ± 1.81 mmHg which was statistically significantly lower than the preoperative measurements (p < 0.001). In the comparison of pre- and postoperative orbital CDU value, the preoperative OA PSV (30.16 ± 5.31 cm/s) and OA EDV (10.93 ± 3.04) values were significantly lower than the postoperative OA PSV (36.21 ± 5.56) and OA EDV (12.84 ± 3.38) values (p < 0.001 and p < 0.05, respectively). A significant correlation was determined between BMI and IOP (r = -0.443; p < 0.05)., Conclusions: Decrease in body weight resulting from bariatric surgery performed on morbid obese patients causes alterations in both IOP and retrobulbar hemodynamics. Morbidly obese patients who undergo bariatric surgery have statistically significantly lower IOP values and increase in OA Doppler parameters (PSV, EDV) than in the preoperative period, which reflects a better retrobulbar and ocular blood flow.

Purpose: To evaluate extraocular orbital vessels with color Doppler ultrasound (CDU) and investigate the effects of severe obstructive sleep apnea (OSA) on retrobulbar blood flow., Methods: Between February 2014 and September 2015, 30 patients with severe OSA (apnea-hypopnea index (AHI) > 30) and 28 controls were prospectively included in this study. Intraocular pressure (IOP) was measured with a Goldmann applanation tonometer, and CDU was used to evaluate the retrobulbar vessels., Results: The mean AHI score for the OSA group was 63.2 ± 21.5 per hour. The IOP values were significantly higher in the severe OSA group (p < 0.05). The central retinal artery peak systolic velocity (PSV) (p < 0.05) and end-diastolic velocity (EDV) (p < 0.02), and the ophthalmic artery (OA) PSV and EDV, were found to be significantly lower in the OSA group (p < 0.05)., Conclusion: Severe OSA causes an increase in IOP and a decrease in flow velocity in the retrobulbar circulation.

Purpose: The aims of this study were to evaluate using testicle apparent diffusion coefficient (ADC) values in patients with varicocele and compare them with those of healthy individuals, to identify an optimal ADC threshold level to predict abnormal semen analysis using diffusion-weighted imaging., Materials and Methods: Thirty-one patients with the diagnosis of varicocele and 20 healthy controls were enrolled in the study. All subjects underwent testicle diffusion-weighted imaging at b values of 0, 400, and 800 s/mm and semen analysis. Student t tests were used to compare continuous variables between 2 groups. Testicle ADC values were correlated with semen analysis parameters. The relationship between ADC values and impaired semen analysis parameters was evaluated using Pearson correlation coefficient analysis. Receiver operating characteristic curves were formed. Cut-off values for ADC, sensitivity, and specificity values were measured., Results: There was a negative correlation between mean ADC values and plexus pampiniformis vein diameter (r = -0.467, P < 0.001) and a positive correlation between mean ADC values and sperm count (r = 0.838, P < 0.001) as well as sperm morphology (r = 0.548, P < 0.05). Sensitivity values of 94.3% and 86.6% and specificity values of 87.5% and 43.8% were determined for the best cut-off ADC values in diagnosing the sperm count and morphology, respectively (area under the curve, 0.961 and 0.781)., Conclusions: Decreased testicular ADC values in patients with varicocele are significantly correlated with semen parameters. This method may be used to determine the degree of testicular parenchymal destruction. In addition, testicular ADC cut-off values might be useful in dyspermia patients for the management of patients with varicocele.

Purpose: To evaluate intraocular pressure (IOP) and extraocular orbital vessels with color Doppler ultrasound (CDU) and investigate the effects of obesity on retrobulbar blood flow., Methods: Fifty-nine patients were included in this prospective study. Patients were divided into two groups according to body mass index: Group 1 (31 obese patients) and Group 2 (28 non-obese patients). IOP was measured with a Goldmann applanation tonometer, and CDU was used to evaluate the retrobulbar vessels., Results: The mean IOP was 18 ± 6.68 mmHg in the obese group and 13.71 ± 1.60 mmHg in the control group (p<0.001). When the CDU values for the central retinal artery were compared between the groups, the pulsatility index was found to be significantly lower in the obese group than in the control group (p<0.001). When the CDU values for the ophthalmic artery (OA) were compared between the groups, the peak systolic velocity (p<0.001) and end-diastolic velocity (p=0.002) values were found to be significantly lower in the obese group than in the control group., Conclusions: Obese patients have a higher mean IOP and lower flow velocity than non-obese patients. Increased IOP together with decreased retrobulbar blood flow, particularly in obese individuals, may increase the risk of glaucoma development.

Introduction: One of the most common otological complaints is tinnitus in adults. When there is a complaint of unilateral tinnitus and retrocochlear pathology is suspected, imaging methods are applied. However, the imaging findings obtained may not always be compatible with the severity and localization of the tinnitus., Aim: The aim of the present study was to determine whether or not there was a significant correlation between the findings on magnetic resonance imaging (MRI) and the presence and severity of tinnitus in patients with the complaint of unilateral tinnitus., Method: The study included 44 patients with no loss of hearing who presented with the complaint of unilateral tinnitus. The relationship between tinnitus severity and vascular loop presence was investigated., Results: Various types of vascular loop were determined in 14 patients. No statistically significant relationship was determined between the presence of vascular loop and the Tinnitus Handicap Inventory scores., Conclusion: The results of this study showed no significant difference in respect of the presence of vascular loop on the MRI findings of symptomatic and healthy ears. The presence of vascular loop on MRI is not always a pathological event and should be considered only as an examination finding that could be an anatomic variation.

Objective: In this study, emergency physicians and on-call radiologists were compared regarding identification of fatal injuries on computed tomographic (CT) scans in patients with trauma., Materials and Methods: Multiply injured patients who were older than 18 years and underwent CT scanning were included in the study. The CT scans were interpreted by the responsible emergency physician. At the same time, these images were also evaluated by the on-call radiologist. Final evaluation was done 1 week later by a radiology instructor who knew the clinical follow-up of the patient., Results: The study included 156 patients. The mean age of the patients included in the study was found to be 41.6 years. Less than half (33.5%) of the patients were female and 86.5% were male. A total of 482 CT scans were performed in the patients. Regarding brain CTs, the concordance rate for emergency physicians was 98%, whereas it was 94% for on-call radiologists. Regarding thoracic CTs, the concordance rate for emergency physicians was 91%, whereas was 93% for on-call radiologists. There was a perfect concordance (κ value > 0.75) for on-call radiologists and emergency physicians in terms of brain and thoracic CTs. Regarding abdominal-pelvic CTs, the concordance rate for emergency physicians was 97%, whereas it was 98% for on-call radiologists. Moderate concordance (κ range = 0.40-0.75) was detected for emergency physicians in terms of identification of liver, spleen, kidney, and intra-abdominal/retroperitoneal hemorrhages. There was a perfect concordance (κ value > 0.75) for pelvic fractures., Conclusion: In this study, it was shown that emergency physicians were successful in identifying fatal injuries on trauma CT images after a short-term training on interpretation of trauma CTs., (Copyright © 2016 Elsevier Inc.

Objective: Silent sinus syndrome (SSS) is a clinical syndrome that occurs as a result of chronic maxillary sinus atelectasis (CMA) and is seen with progressive enophthalmos and hypoglobus. The aim of this study was to investigate the correlation between radiological findings and clinical findings in patients with radiologically asymmetrical reduced maxillary sinus volume., Material and Method: A comparison was made of patients with CMA through evaluation of paranasal sinus computed tomography, magnetic resonance imaging examination of maxillary sinus volume of the CMA side and the contralateral side, thickness of the retroantral fat tissue, infraorbital bone curve, uncinate process lateralisation measurement, middle concha diameter, and calculation of the change in location of the inferior rectus muscle., Results: The study included 16 patients. Although a statistically significant difference was determined between the healthy and the pathological sides in respect to maxillary sinus volume, thickness of the retroantral fat tissue, infraorbital bone curve, uncinate process lateralisation measurement, and middle concha diameter (p = 0.00, p = 0.002, p = 0.020, p = 0.020, p = 0.007), no significant difference was determined in respect to the change in location of the inferior rectus muscle (p = 0.154). A positive correlation was determined between the increase in sulcus depth and maxillary sinus volume and inferior orbital bone curve (p < 0.05)., Conclusion: In CMA patients suspected of having SSS, radiological maxillary sinus volume analysis, determination of retroantral fat thickness, measurement of the infraorbital bone curve, and measurement of the uncinate process lateralisation can be used as objective tests. However, it should be kept in mind that radiological findings may not always be compatible with the ophthalmological examination findings., (Copyright © 2016 European Association for Cranio-Maxillo-Facial Surgery.

Objectives: This study aims to evaluate the role of diffusion-weighted imaging in detection of active sacroiliitis and compare the apparent diffusion coefficient (ADC) and normalized relative ADC (r-ADC) values by using vertebra and iliac wings as reference organs., Patients and Methods: The study included 56 patients (26 males, 30 females; mean age 37.7±10.1 years; range 18 to 66 years) with chronic back pain and without history of sacroiliitis who underwent magnetic resonance imaging. T2-weighted spectral presaturation with inversion recovery, contrast-enhanced T1-weighted spectral presaturation with inversion recovery, and diffusion-weighted (b values: 0 and 600 s/mm2) images were obtained. All images were evaluated by two different radiologists for interobserver variability. All individuals were grouped in either mechanical low back pain (control group) or active sacroilitis (disease group) groups according to the presence or absence of MRI findings of active sacroilitis. ADC values of both surfaces were measured from normal and affected areas of joints. Also, ADC values of L5 vertebra and iliac wings were measured as reference organs to calculate r-ADC values., Results: Mean ADC and r-ADC values measured from lesions were significantly higher than that of normal appearing bone marrow areas in both patients with mechanical low back pain (n=17) and active sacroiliitis (n=39). Both ADC values and r-ADC values could differentiate active lesions from normal appearing bone marrow areas as well as contrast-enhanced T1-weighted images. According to r-ADC values calculated with the L5 vertebra, unaffected portions of bone marrow areas in patients with sacroiliitis were normalized whereas r-ADC remained higher than normal in affected portions of the bones., Conclusion: Diffusion-weighted imaging is a fast, sensitive magnetic resonance imaging sequence in detection of active sacroiliitis. It does not require contrast agent and can be safely used as an adjunct to conventional magnetic resonance images. r-ADC is also highly sensitive in detecting active sacroiliitis and may be used as an alternative to standard ADC measurements for the demonstration of inflammation. It helps eliminate individual bone marrow differences by using patients' own normal bone marrow measurements and increases diagnostic accuracy., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article.

Background/aims: To determine the role of serum procalcitonin levels and ascites/subcutaneous echogenicity ratio (ASER) in predicting ascites infection in hospitalized cirrhotic patients., Materials and Methods: A total of 50 patients hospitalized because of cirrhosis-related ascites were included in this study. In these patients, 44% of ascites were infected (peritonitis), whereas 56% of ascites were sterile. These two groups were compared in terms of procalcitonin levels and ASER for predicting ascites infection. Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic performance of ASER, and the predicting outcome of ASER was compared with procalcitonin levels., Results: The ASER values of the patients with the diagnosis of infected ascites were significantly higher than in those with the diagnosis of sterile ascites (p<0.001). ROC analysis was performed to determine the diagnostic ASER value for infected ascites. An ASER greater than 0.0019 determined peritonitis with 95.5% sensitivity and 100% specificity. A procalcitonin level greater than 0.05 determined peritonitis with 86.4% sensitivity and 75% specificity. Using ROC analysis, an ASER greater than 0.0019 [area under curve (AUC): 0.974, 95% confidence interval (CI) (0.884-0.999, p<0.001)] was a significantly better diagnostic marker than a procalcitonin level >0.5 mg/dL [AUC: 0.860, 95% CI (0.884-0.999, p<0.001) (p<0.045)]., Conclusion: According to our findings, the determination of ASER and serum procalcitonin levels seems to provide satisfactory diagnostic accuracy in differentiating ascites infections in hospitalized cirrhotic patients. ASER values significantly differentiate ascites infections better than procalcitonin levels.

Purpose: Remarkable differences in weight loss have been observed in obese patients undergoing laparoscopic sleeve gastrectomy (LSG). These high variations might be partly explained by genetic factors. The rs9939609 fat mass and obesity-associated gene (FTO) polymorphism has been implicated in the susceptibility of obesity. We aimed to explore the effects of the rs9939609 FTO gene polymorphism on weight loss among severely obese patients applying for LSG., Materials and Methods: All individuals were analyzed for the FTO rs9939609 gene polymorphism. A total of 74 morbid obese patients (20 male, 54 female) were operated. Body weight and body mass index (BMI) were measured at before LSG and after surgery at the sixth month., Results: Twenty-eight patients (37.8%) had genotype TT (wild-type allel), 36 patients (48.6%) had genotype TA, and 10 patients (13.5%) had genotype AA. In both wild-type group and mutant group, BMI and weight levels decreased at the sixth month after surgery. Percent of excess weight loss (EWL) at 6 months of follow-up was similar in both groups. There were no differences between the mutant and wild-type groups percent of EWL at the sixth month after applying LSG., Conclusion: Our data showed that the rs9939609 FTO gene polymorphism is not a useful genetic test prior to LSG to help clinicians predicting the weight loss for severely obese patients in short-term follow-up.

The aim of our study was to determine the incidence of developmental hip dysplasia (DHD) in the Western Mediterranean Region of Turkey and evaluate follow-up results of physiologically immature hips classified as type 2 according to Graf classification. Ultrasononographic examinations of the hips were performed using Graf's technique on 1162 infants (2324 hips) referred to our clinic for hip ultrasounds between March 2013 and March 2014. DHD was detected in 1.36% of 1162 infants. Among infants who were brought into repetitive follow-ups, 191 out of type 2a hip displasias of 201 infants were improved to type 1 and 10 type 2a hip dysplasias worsened. Sonographically worsened tip 2a group consisted of 4 type 2b, 6 type 2c DHDs. Hip ultrasound performed during neonatal period and infancy in the detection of developmental hip dysplasias and follow-up of hip dysplasias diagnosed as type 2a convey importance because of sonographically detected potential deterioration.

Objective: To demonstrate utility and safety of the puncture aspiration injection and reaspiration (PAIR) technique for outpatients., Methods: Percutaneous treatment with US guidance was applied to 33 patients for 44 cysts. Patients treated with the PAIR technique, were outpatients. PAIR and catheterization technique were evaluated for efficacy and safety of procedure and complication rates., Results: Thirty-five of 44 cysts were treated with the PAIR and 9 of 44 were treated with the catheterization technique. The success rate of the cysts Gharbi type 1 (CE1) and type 2 (CE3a) treated with the PAIR technique was 100%. In the follow up of 9 cysts treated with the catheterization technique, 2 of them (22%) developed cyst infection and 1 (11%) developed a biliary fistula., Conclusions: The PAIR technique was found to be an effective and safe approach in order to treat Gharbi type 1 and type 2 cysts percutaneously for outpatients. It has a very low complication rate in comparison with the catheterization technique. So every effort should be made to finish the treatment with PAIR technique., (Copyright © 2014 Hainan Medical College. Published by Elsevier B.V. All rights reserved.)
