Abstract

Introduction: The aim of this study was to evaluate radiologically the effects of long-term luteinizing hormone-releasing hormone (LHRH) agonist therapy on extraocular muscle thickness, retrobulbar orbital fat (ROF), and the optic nerve (ON) in prostate cancer (PCa) patients. Methods: The retrospective study included patients with primary or recurrent PCa who received androgen deprivation therapy (ADT) for at least 12 months. Each patient underwent gallium-68 prostate-specific membrane antigen positron emission tomography-computed tomography both before and at the end of the 12-month treatment. Thickness of the ON, lateral rectus muscle, medial rectus muscle, superior rectus muscle, and inferior rectus muscle were measured by using the coronal CT sections in soft tissue window. ROF, ocular protrusion, and ON length were measured in sagittal and coronal planes. Changes in these anatomical structures induced by LHRH analogs were investigated by comparing pre- and post-treatment measurements. Results: A total of 57 patients were included in the study. Median PSA and TT values ​​of the patients before treatment were 36.5 (range, 19.6–51.2) ng/mL and 614.0 (range, 472.0–743.0) ng/dL, respectively, and these values ​​decreased significantly after the treatment (10.6 [range, 5.2–14.2] ng/mL and 36.5 [range, 19.6–51.2] ng/dL, respectively, p < 0.001 for both). After the treatment, there was a statistically significant decrease in the areas of inferior rectus muscle, superior rectus muscle, lateral rectus muscle, and medial rectus muscle (p < 0.001 for all), while significant increases were observed in ROF (11.9%, p < 0.001) and ON thickness (14.3%, p = 0.004). The amount of ocular protrusion also showed a significant increase of approximately 14% after the treatment (14.0 [range, 12.0–16.0] mm vs. 16.0 [range, 14.0–17.2] mm, p < 0.001). Discussion/Conclusion: Our findings, for the first time in the literature, indicated that ADT causes a decrease in extraocular muscle mass and an increase in ROF with ocular protrusion. It can be asserted that these changes are similar to the changes in skeletal muscle and fat mass in other body parts. Further studies with a higher level of evidence are needed to clinically evaluate the increase in ocular protrusion and ON enlargement, which are likely to be caused by the increase in ROF.

Abstract

Post-prostatectomy stress incontinence (PPI) is an important health problem for patients with radical prostatectomy history. Duloxetine is a common drug, used in PPI with the out of indications in most countries. In this study, we aimed to evaluate the prophylactic effect of duloxetine administration in PPI during the early postoperative period in patients undergoing laparoscopic radical prostatectomy (LRP). The retrospective study included 209 patients who underwent LRP. Patients were divided into two groups: Group I (n=96) was initiated on pelvic floor exercises (PFE) + duloxetine in the early postoperative period and continued this regimen for a total of 12 weeks and Group II (n=113) only performed PFE for 12 weeks after surgery. Exclusion criteria were as follows: a history of neuromuscular dysfunction of bladder, post-prostatectomy urge incontinence, receiving adjuvant radiotherapy during the 12- week period, prior anti-incontinence surgery, and post-voiding urine>100 ml. The prevalence rates of urinary incontinence measured at the time of urinary catheter removal (baseline) and at weeks 3, 6, and 12 after surgery and the number of wet pads per day were compared. The study included 209 patients with a mean age of 60.68 ± 7.16 years. Baseline urinary continence rates were similar in Group I and Group II (29.2% vs. 35.4%, p=0.338). At 12 weeks, although PPI rates have decreased in both groups, there was no difference between Group I and Group II (15.6% vs. 24.8%, p=0.103). Administration of prophylactic duloxetine in the early postoperative period, which started without regard to the positivity of PPI, is not significantly effective to early postoperative urinary continence recovery.

Abstract

Resumo Fundamento: Não há estudos avaliando o intervalo Tpico-Tfim (Tpe), a relação Tpe/QT e a relação Tpe/QTc para avaliar arritmias cardíacas em pacientes com COVID-19. Objetivo: Visamos investigar se há alterações nos intervalos QT, QTc e Tpe e nas relações Tpe/QT e Tpe/QTc em pacientes com COVID-19. Métodos: O estudo incluiu 90 pacientes com infecção por COVID-19 e 30 controles saudáveis pareados por sexo e idade. Foram aferidos os intervalos QT, QTc e Tpe e as relações Tpe/QT e Tpe/QTc. Os participantes incluídos no estudo foram divididos nos seguintes 4 grupos: controles saudáveis (grupo I), pacientes com COVID-19 sem pneumonia (grupo II), pacientes com COVID-19 e pneumonia leve (grupo III) e pacientes com COVID-19 e pneumonia grave (grupo IV). Significância estatística foi definida por valor p < 0,05. Resultados: Verificou-se que a frequência cardíaca basal, a presença de hipertensão e diabetes, a contagem de leucócitos, o nitrogênio ureico no sangue, a creatinina, o potássio, o aspartato aminotransferase, a alanina aminotransferase, o NT-proBNP, a proteína C reativa de alta sensibilidade, o dímero-D, a TncI-as, o intervalo Tpe, a relação Tpe/QT e a relação Tpe/QTc aumentaram do grupo I para o grupo IV e foram significativamente mais altos em todos os pacientes do grupo IV (p < 0,05). A pressão arterial sistólica, a hemoglobina e os níveis de cálcio eram menores no grupo IV e significativamente menores em comparação com os demais grupos (< 0,05). Os intervalos QT e QTc eram semelhantes entre grupos. Determinou-se que os níveis elevados de frequência cardíaca, cálcio, dímero-D, NT-proBNP e PCR-as eram significativamente relacionados a Tpe, Tpe/QT e Tpe/QTc. Conclusões: Em pacientes com COVID-19 e pneumonia grave, o intervalo Tpe, a relação Tpe/QT e a relação Tpe/QTc, que estão entre os parâmetros de repolarização ventricular, foram aumentados, sem prolongação dos intervalos QT e QTc. A partir deste estudo, não podemos definitivamente concluir que as alterações eletrocardiográficas observadas estão diretamente relacionadas à infecção por COVID-19 ou à inflamação, mas sim associadas a cenários graves de COVID-19, que podem envolver outras causas de inflamação e comorbidades. Abstract Background: There is no study evaluating the Tpeak-Tend (Tpe) interval, Tpe/QT ratio, and Tpe/QTc ratio to assess cardiac arrhythmias in patients with COVID-19. Objective: We aimed to examine whether there is a change in QT, QTc, Tpe interval, Tpe/QT ratio, and Tpe/QTc ratio in patients with COVID-19. Methods: The study included 90 patients with COVID-19 infection and 30 age-and-sex-matched healthy controls. QT, QTc, Tpe interval, Tpe/QT ratio, and Tpe/QTc ratio were measured. The participants included in the study were divided into the following 4 groups: healthy controls (group I), patients with COVID-19 without pneumonia (group II), patients with COVID-19 and mild pneumonia (group III), and patients with COVID-19 and severe pneumonia (group IV). Statistical significance was set at p < 0.05. Results: It was found that baseline heart rate, presence of hypertension and diabetes, white blood cell count, blood urea nitrogen, creatinine, potassium, aspartate aminotransferase, alanine aminotransferase, NT-proBNP, high sensitive C reactive protein, D-dimer, hs-cTnI, Tpe, Tpe/QT, and Tpe/QTc increased from group I to group IV, and they were significantly higher in all patients in group IV (p < 0.05). Systolic-diastolic blood pressure, hemoglobin, and calcium levels were found to be lowest in group IV and significantly lower than in other groups (< 0.05). QT and QTc intervals were similar between groups. It was determined that increased heart rate, calcium, D-dimer, NT-proBNP and hs-CRP levels were significantly related to Tpe, Tpe/QT, and Tpe/QTc. Conclusions: In patients with COVID-19 and severe pneumonia, Tpe, Tpe/QT ratio, and Tpe/QTc ratio, which are among ventricular repolarization parameters, were found to be increased, without prolonged QT and QTc intervals. In this study, we cannot definitively conclude that the ECG changes observed are directly related to COVID-19 infection or inflammation, but rather associated with severe COVID-19 scenarios, which might involve other causes of inflammation and comorbidities.

Abstract

SUMMARY: Dextrocardia with situs inversus is an uncommon anomaly affecting about 1 to 2 per 10,000 in the general population. This report describes an adult male patient with dextrocardia and in a Turkish subject. The photographic illustrations revealed transposition of some of the visceral organs such as the spleen was located right and the liver and gall bladder on the left. The heart was flattened and flipped to the right. Many people with situs inversus totalis are unaware of their unusual anatomy until they seek medical attention for an unrelated condition. So, early detection may lead to a successful surgical management and consequently offer a safer chance of survival. This report showed that dextrocardia and situs inversus can be seen amongst Turkish subjects. RESUMEN: La dextrocardia con situs inversus es una anomalía poco frecuente que afecta aproximadamente de 1 a 2 personas por 10.000 en la población general. Este informe describe un paciente masculino adulto con dextrocardia. Las figuras revelaron que la transposición de algunos de los órganos viscerales, como el bazo, se ubicada a la derecha y el hígado y la vesícula biliar a la izquierda. El corazón fue aplastado y girado hacia la derecha. Muchas personas con situs inversus totalis desconocen su anatomía inusual hasta que buscan atención médica por una afección no relacionada. Por lo tanto, la detección temprana puede llevar a un manejo quirúrgico exitoso y, en consecuencia, ofrecer una posibilidad más segura de supervivencia. Este informe mostró que la dextrocardia y el situs inversus se pueden encontrar entre los sujetos turcos.

Abstract

We report the case of a 23-year-old male with thalassemia major who developed long QT and continuous ventricular tachycardia (VT). Electrocardiography, echocardiography, and cardiac magnetic resonance imaging (MRI) were used for diagnosis and risk stratification. VT causes and treatments are presented and discussed. Ventricular arrhythmia can be treated by normalizing QT interval with high-dose beta-blocker therapy. However, MRI-compatible internal cardiac defibrillator implantation was performed due to the high risk in this patient.

Abstract

Objective To present clinical, chromosomal and hormonal features of ten cases with SRY-positive 46,XX testicular disorder of sex development who were admitted to our infertility clinic. Cases and Methods Records of the cases who were admitted to our infertility clinic between 2004 and 2015 were investigated. Ten 46,XX testicular disorder of sex development cases were detected. Clinical, hormonal and chromosomal assessments were analized. Results Mean age at diagnosis was 30.4, mean body height was 166.9cm. Hormonal data indicated that the patients had a higher FSH, LH levels, lower TT level and normal E2, PRL levels. Karyotype analysis of all patients confirmed 46,XX karyotype, and FISH analysis showed that SRY gene was positive and translocated to Xp. The AZFa, AZFb and AZFc regions were absent in 8 cases. In one case AZFb and AZFc incomplete deletion and normal AZFa region was present. In the other one all AZF regions were present. Conclusion Gonadal development disorders such as SRY-positive 46,XX testicular disorder of sex development can be diagnosed in infertility clinics during infertility work-up. Although these cases had no chance of bearing a child, they should be protected from negative effects of testosterone deficiency by replacement therapies.

Abstract

Purpose: To identify any relationship between known reasons of male infertility and 2D:4D ratio. Materials and Methods: A total of 371 males were included in the study. The cases were grouped into 6 groups including sperm count < 5 million/mL, sperm count = 5 million/mL, Klinefelter Syndrome, hypogonadotropic hypogonadism, vasal agenesis and control. Groups were compared with each other in terms of 2D:4D ratios and groups with a 2D:4D ratios below 1 and equal/above 1 were compared. Results: The greatest ratios were in the vasal agenesis and hypogonadotropic hypogonadism groups and analysis of the data with logistic regression analysis showed that there was a significant difference in terms of 2D:4D ratios for these groups when comparing with control group. The other groups showed no statistically significant differences. Conclusion: The results of the present study showed some significant difference between 2D:4D ratios for the subgroups of the fertile and infertile cases. Although, 2D:4D ratio is not an unaccompanied parameter to reveal causes of male infertility, it can be associated with some situations that are related with male infertility. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: The aim of this study is to investigate whether P wave dispersion (PWD), measured before, during and after fibrinolytic therapy (FT,) is able to predict successful reperfusion and infarct related artery (IRA) patency in patients with acute anterior MI who received FT. Methods: Sixty-eight patients who presented with acute anterior MI were enrolled in the study. An electrocardiogram was performed before and at 30, 60, 90 and 120 minutes after the start of FT. PWD was defined as the difference between maximum and minimum P wave duration on standard 12-lead surface electrocardiogram. A multivariate logistic regression model was used to assess whether PWD was predictor of IRA patency and ST-segment resolution (STR) on electrocardiogram. Results: PWD120 was significantly lower in patients with STR on electrocardiogram (38 patients) compared with those without STR (30 patients) (44.8±11.5 vs. 52.9±10.3 ms; p < 0.001). PWD120 was found to be significantly lower in patients with patent IRA (31 patients) compared to those with occluded IRA (37 patients) (42.3±9.7 vs. 53.5±10.6 ms; p < 0.001). Logistic regression analysis revealed that PWD120 significantly predicted STR and IRA patency. A ≥51.6 ms PWD120 can predict an occluded IRA with a 87% sensitivity, ≥51 ms PWD120 can predict no reperfusion with a 74% sensitivity. Conclusion: PWD values, which were higher than 51 ms and 51.6 ms in patients who received fibrinolytic therapy, can serve as a marker of failed reperfusion and occluded IRA. PWD values, in combination with other reperfusion parameters, can contribute to the identification of rescue PCI candidates.

Abstract

Introduction. There are controversial results in the risk of atrial fibrillation as well as arrhythmogenic potential of bisphosphonates. Method. 37 patients and 40 healthy controls were evaluated prospectively with regard to the cardiac side effects related to the use of zoledronic acid (ZA) and its effects on electrocardiography (ECG) parameters. Result. As the basal ECG results of the patients diagnosed with cancer compared with the control group, it was determined that QT maximum was significantly lower, QT minimum was significantly higher. However; it was determined that QT disp, P max, P min, and P disp values were not significantly different. There was no statistically significant difference in P max, P min, P disp, QT max, QT min, QT disp values of the ECG parameters measured from cancer patients, before and 60 minutes after ZA therapy. Conclusion. There were no significant alterations in ECG in the acute period, indicated that ZA had no arrhythmia potential in the early period in patients with no underlying cardiac disease. However: patients receiving ZA should be monitored more closely because of the risk of arrhythmia which may ensue due to hypocalcemia, hypomagnesemia, or other chemotherapeutics.

Abstract

Purpose: The present study was designed to compare the efficacy of alfuzosin therapy as an alpha-blocker in metabolic syndrome (MetS) and non-MetS patients with moderate lower urinary tract symptoms (LUTS).Material and Methods: This prospective study included male patients with obstructive voiding and had a moderate LUTS according to International Prostate Symptom Score (IPSS). Patients were divided into two groups: MetS and Non-MetS. Following the measurement of uroflowmetric parameters (maximum flow rate [Qmax], post-void residual volume [PVR], urine volume) and the determination of IPSS scores, the patients were initiated on alfuzosin 10 mg once daily for a period of 12 weeks. At the end of the therapy, treatment outcomes were determined based on uroflowmetric parameters and IPSS scores.Results: 301 patients were included in the study (MetS: 160, non-MetS: 141). Pre-treatment uroflowmetric measurements and IPSS scores were similar in both groups. After the therapy, the median Qmax level increased from 12.80 (10.62-14.82) ml/s to 14.55 (12.00-16.60) ml/s in the MetS group and from 12.60 (8.60-14.60) ml/s to 15.70 (13.20-17.20) ml/s in the non-MetS group (p<0.001 for both). Similar statistically significant changes were valid for PVR and IPSS. Post-treatment Qmax, PVR values and IPSS scores were higher in the non-MetS patients compared to MetS patients.Conclusion: Although the non-MetS patients had greater benefit from the alfuzosin therapy compared to the MetS patients, alfuzosin is an effective alpha-blocker in the treatment of MetS patients with moderate LUTS. Based on these findings, it is tempting to consider that MetS might be a negative factor for benign prostate hyperplasia treatment. [ABSTRACT FROM AUTHOR]

Abstract

WOS: 000456210100006 PubMed ID: 30723681 Objective: The aim of our study is to evaluate the functional outcomes and quality of life in adult ipsilateral femur and tibia fractures. Methods: 26 patients (21 male, 5 female; mean age 30 years, range: 18 to 66) treated for adult ipsilateral femur and tibia fractures were evaluated retrospectively. For femur fractures, intramedullary nails were used in 15 patients (12 antegrade, 3 retrograde), plate in 11 patients (10 locked-plate, and 1 blade-plate with a 95 degree angle). For tibia fractures, locked-plate were used in 13 patients, intramedullary nails in 9 patients, external fixator in 3 patients and multiple screws in 1 patient. According to Blake and McBryde classification, 17 fractures were type I, 9 fractures were type II (7 type 2A and 2 type 2B). The functional outcomes were evaluated by Karlstrom and Olerud criteria, and quality of life was evaluated by Short Form-36. The mean follow-up duration was 4.4 years (range: 1.1 to 7.3 years). Results: The functional outcomes were excellent in 6 patients, good in 8 patients, acceptable in 6 patients and poor in 6 patients. The mean values of quality of life scales were; physical function: 64.8, physical role limitation: 60.5, pain: 68.2, general health: 63.3, vitality: 58.4, social function: 68.2, emotional role limitation: 62.7, and mental health: 65.8. Conclusion: Adult ipsilateral femur and tibia fractures are severe injuries and adversely affect the quality of life and functional outcomes. The quality of life scales should be used along with functional outcome scores in evaluating these injuries. The translational potential of this article: Adult ipsilateral femur and tibia fractures cause severe morbidity. Functional outcomes and quality of life scales should be used together to evaluate these fractures. Karlstrom and Olerud criteria for functional outcomes and Short Form-36 scales for quality of life are suitable methods to evalute these fractures. (C) 2018 The Authors.

Abstract

Background: There is no study evaluating the Tpeak-Tend (Tpe) interval, Tpe/QT ratio, and Tpe/QTc ratio to assess cardiac arrhythmias in patients with COVID-19., Objective: We aimed to examine whether there is a change in QT, QTc, Tpe interval, Tpe/QT ratio, and Tpe/QTc ratio in patients with COVID-19., Methods: The study included 90 patients with COVID-19 infection and 30 age-and-sex-matched healthy controls. QT, QTc, Tpe interval, Tpe/QT ratio, and Tpe/QTc ratio were measured. The participants included in the study were divided into the following 4 groups: healthy controls (group I), patients with COVID-19 without pneumonia (group II), patients with COVID-19 and mild pneumonia (group III), and patients with COVID-19 and severe pneumonia (group IV). Statistical significance was set at p < 0.05., Results: It was found that baseline heart rate, presence of hypertension and diabetes, white blood cell count, blood urea nitrogen, creatinine, potassium, aspartate aminotransferase, alanine aminotransferase, NT-proBNP, high sensitive C reactive protein, D-dimer, hs-cTnI, Tpe, Tpe/QT, and Tpe/QTc increased from group I to group IV, and they were significantly higher in all patients in group IV (p < 0.05). Systolic-diastolic blood pressure, hemoglobin, and calcium levels were found to be lowest in group IV and significantly lower than in other groups (< 0.05). QT and QTc intervals were similar between groups. It was determined that increased heart rate, calcium, D-dimer, NT-proBNP and hs-CRP levels were significantly related to Tpe, Tpe/QT, and Tpe/QTc., Conclusions: In patients with COVID-19 and severe pneumonia, Tpe, Tpe/QT ratio, and Tpe/QTc ratio, which are among ventricular repolarization parameters, were found to be increased, without prolonged QT and QTc intervals. In this study, we cannot definitively conclude that the ECG changes observed are directly related to COVID-19 infection or inflammation, but rather associated with severe COVID-19 scenarios, which might involve other causes of inflammation and comorbidities.

Abstract

Introduction: Atrial fibrillation (AF) attacks can be silent, symptomatic, or emerge with its complications in pacemaker-implanted patient groups. P-wave duration index (PWDI), a novel parameter, is calculated by dividing the P-wave duration (PWD) by the PR interval. This study aimed to investigate the relation between PWDI and silent AF development in cardiac resynchronisation therapy defibrillator (CRT-D)-applied patients., Material and Methods: The study population consisted of 181 CRT-D device-implanted patients. Atrial fibrillation attacks that last at least 30 s with no symptoms were accepted as silent AF., Results: Patients were separated into two groups: "with silent AF" and "without silent AF". The without silent AF group comprised 121 patients (mean age: 62.9 ±8.7 years, 62% male). The with silent AF group included 60 patients (mean age: 67.9 ±9.7 years, 60% male). The silent AF group had significantly higher mean age ( p = 0.001). PR duration was significantly higher in the without silent AF group ( p = 0.001). Patients with first-degree IAB and PWDI values were significantly higher in the with silent AF group ( p -values were 0.001 and < 0.001, respectively). Age (OR = 1.073, 95% CI: 1.028-1.119, p = 0.001) and PWDI (OR = 1.053, 95% CI: 1.028-1.078, p < 0.001) were detected as independent predictors for silent AF in the binomial logistic regression analysis. In the ROC analysis, a PWDI cut-off value of 0.67 determined silent AF with 81.7% sensitivity and 51.4% specificity (AUC = 0.701, p < 0.001)., Conclusions: P-wave duration index was significantly associated with silent AF in patients with CRT-D., Competing Interests: The authors declare no conflict of interest.

According to Blake and McBryde classification, 17 fractures were type I, 9 fractures were type II (7 type 2A and 2 type 2B). The functional outcomes were evaluated by Karlström and Olerud criteria, and quality of life was evaluated by Short Form-36. The mean follow-up duration was 4.4 years (range: 1.1 to 7.3 years)., Results: The functional outcomes were excellent in 6 patients, good in 8 patients, acceptable in 6 patients and poor in 6 patients. The mean values of quality of life scales were; physical function: 64.8, physical role limitation: 60.5, pain: 68.2, general health: 63.3, vitality: 58.4, social function: 68.2, emotional role limitation: 62.7, and mental health: 65.8., Conclusion: Adult ipsilateral femur and tibia fractures are severe injuries and adversely affect the quality of life and functional outcomes. The quality of life scales should be used along with functional outcome scores in evaluating these injuries., The Translational Potential of This Article: Adult ipsilateral femur and tibia fractures cause severe morbidity. Functional outcomes and quality of life scales should be used together to evaluate these fractures. Karlström and Olerud criteria for functional outcomes and Short Form-36 scales for quality of life are suitable methods to evalute these fractures.

Abstract

This study aimed at determining the choice and administration duration of ideal antibiotic prophylaxis before percutaneous nephrolithotomy (PNL) operation, a treatment modality for nephrolithiasis. The study included 90 patients who had no internal problem, yet had a negative urine culture and underwent a PNL operation. We compared infection rates between ciprofloxacin and ceftriaxone groups and their subgroups. The results showed no statistical difference between ciprofloxacin and ceftriaxone groups in terms of systemic inflammatory response syndrome (SIRS) (CIP(P) = 0.306,  CTX P = 0.334. As a result of this study no statistical difference was observed between ciprofloxacin and ceftriaxone in terms of SIRS. It seems, however, reasonable to choose ceftriaxone, considering antibiotic sensitivity of microorganisms and detection of three cases accepted as urosepsis in the ciprofloxacin group. As there is no difference between short, and long-term prophylactic use of these antibiotics, preference of short-term prophylaxis for patients with no risk of infection will be important to avoid inappropriate antibiotic usage.
