RESUMO

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.

RESUMO

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/m2, and mean IOP value was 18.2 ± 2.06 mmHg. At 6 months postoperatively, mean BMI and IOP were 36.28 ± 5.41 kg/m2 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.

RESUMO

OBJECTIVE: The current study aimed to investigate the effects of varicocele on testis parenchyma by using ZOOMit DWI and conventional DWI and to compare both diffusion methods. SUBJECTS AND METHODS: Forty-five patients with unilateral varicocele diagnosed by physical examination and color Doppler ultrasound between July 2015 and December 2015 and 32 healthy volunteers were included in the study. ZOOMit and conventional DWI were performed for all patients with a 3-T MRI scanner. RESULTS: Apparent diffusion coefficient (ADC) values calculated using both conventional and ZOOMit DWI decreased in the patients with varicocele of the testis, when compared with the healthy volunteer control group. Furthermore, it was determined that conventional and ZOOMit ADC values for the contralateral side without varicocele also decreased when compared with the healthy volunteer control group (p < 0.05). However, there was no statistically significant difference between testes with or without varicocele in terms of conventional ADC values (p = 0.183), whereas ZOOMit ADC values for testes with varicocele were found to be statistically significantly lower than those for testes without varicocele (p < 0.05). A significant negative correlation was found between venous diameter measured both at rest and during the Valsalva maneuver and ZOOMit ADC values in testes with varicocele. CONCLUSION: For patients with varicocele, conventional and ZOOMit DWI may be predictive of histopathologic changes in the testis, and ZOOMit DWI may be more effective in the diagnosis, treatment, and postoperative response in patients with varicocele when compared with conventional DWI.

RESUMO

BACKGROUND: Acute inflammation induced by COVID-19 may lead to atherosclerotic plaque development or complicate existing plaque. In this study, we aimed to determine the atherogenic effect of COVID-19 pneumonia, confirmed by thoracic computed tomography, on coronary and carotid arteries in patients who recovered from the disease. METHODS: Our study included patients who were diagnosed with COVID-19 in our hospital at least 1 year ago, recovered, and then underwent coronary CT angiography with suspected coronary artery disease. The aim was to evaluate the burden of atherosclerotic plaque in the coronary arteries of these patients who underwent coronary CT angiography. RESULTS: Patients were assigned to 3 groups according to the results of the CT scan. Group 1 included patients in the control group with no history of COVID-19 (n=36), group 2 included those with mild to moderate pneumonia symptoms (n=43), and group 3 included those with severe pneumonia symptoms (n=29). The calcium scores were 23.25±36.8 in group 1, 27.65±33.4 in group 2, and 53.58±55.1 in group 3. The calcium score was found to be significantly higher in group 3 patients with severe pneumonia (group 1-2 p=0.885, group 1-3 p<0.05, group 2-3 p<0.05). CONCLUSION: Although there is no conclusive evidence of a relationship between COVID-19 and atherosclerosis, our study suggests a possible relationship between them. Since this relationship was found especially in cases with severe disease in our study, we believe that the treatment should focus on preventing excessive inflammatory response, and such patients should be under control in terms of coronary artery disease.

RESUMO

Idiopathic granulomatous mastitis (IGM) is a rare inflammatory breast disease that can be clinically and radiologically mistaken for carcinoma. Although its etiology remains uncertain, potential associations with pregnancy, lactation, hormonal imbalances, autoimmunity, smoking, and various microorganisms have been suggested. This study aimed to evaluate the relationship between IGM and oral health. We included 42 female patients diagnosed with IGM based on histopathological evaluations conducted between September 2018 and October 2023. The reference group consisted of 47 female patients with clinically, radiologically, and laboratory-proven non-specific mastitis and 36 healthy female individuals. The oral health of all participants was evaluated by an experienced dentist using the "Decayed, Missing and Filled Teeth" (DMFT) index and the "Simplified Oral Hygiene Index" (OHI-S). The ages of IGM patients included in this study ranged from 29 to 51 years, with a mean age of 34.88 ± 4.87 years. The most common clinical findings were pain (n = 38), palpable breast mass, erythema, induration, and dermal sinus. Comparison of the OHI-S and DMFT index values among participants revealed that those diagnosed with IGM had significantly higher values than those in the reference group (P < 0.05). Our findings suggest a potential involvement of poor oral health in the etiology of IGM. Future studies should consider oral health as a factor in IGM etiology and explore the oral microbiota in samples obtained from the affected tissue.

RESUMO

AIM: To determine the effectiveness of diffusion tensor imaging (DTI) in diagnosing cervical spondylotic myelopathy (CSM) in patients with no findings detected in conventional magnetic resonance imaging (MRI). MATERIAL AND METHODS: Fifty-four patients who presented for cervical MRI between January 2016 and June 2016, with symptoms such as neck pain, paresis, and numbness in hands, were included in the study. The patients were split into four groups based on their degrees of spinal stenosis. The obtained data were examined using special software and color-coded fractional anisotropy (FA), and apparent diffusion coefficient (ADC) maps were formed. Through these maps, using regions of interest (ROIs), FA and ADC values were calculated and the contribution of these values to the diagnosis was evaluated statistically. RESULTS: When all grades of cervical spinal canal stenosis were compared, a statistically significant negative correlation between spinal canal stenosis degree and FA values, and a positive correlation between stenosis degree and ADC values were noted (p < 0.001). In the comparison of stenotic levels and non-stenotic levels for the grade 2 patient group, there was a statistically significant decrease in FA values and an increase in ADC values in stenotic levels compared with prestenotic and poststenotic levels (p < 0.05). CONCLUSION: DTI and quantitative FA and ADC measurements are candidate imaging techniques for the diagnosis of early-stage CSM, which shows no findings in conventional MRI, and determining the degree of spinal cord injury.

RESUMO

Background: We describe the incidental detection of patients infiltrates due to COVID-19 in lung basal sections in patients undergoing abdominal computed tomography (CT) with flank pain attending the urology outpatient clinic during the current pandemic. Methods: We retrospectively analysed 276 patients admitted to the Siirt Training and Research Hospital Urology outpatients clinic between 15 March 2020 and 9 August 2020 with a complaint of flank pain and undergoing non-contrast abdominal CT. A total of 10 patients with COVID-19 compatible findings in CT were defined as the study group. A control group was formed from 10 patients with only urological pathologies (kidney stones, ureteral stones, and hydronephrosis) without a COVID-19 compatible appearance on CT. Results: Ten (3.6 %) patients were identified with COVID-19 and pneumonic infiltrations in the basal regions of the lungs; diagnosis was made by cross-sectional abdominal CT. The visual analog scale (VAS) score of flank pain was significantly higher in the control group (p<0.001); these subjects had urological pathology and no evidence of COVID-19 in the basal regions of the lungs on abdominal CT. There were no signs of COVID-19 disease detected during the admissions procedure in the urology outpatient clinic, including fever, cough, and shortness of breath. Conclusion: During the COVID-19 pandemic, it is important to consider a diagnosis of COVID_19 in patients reporting non-severe flank pain if no urological pathology is evident on abdominal CT scans.

RESUMO

OBJECTIVE: Non-vascular complications following renal transplantation can cause graft failure. In this study, we present our two-year experience with percutaneous treatment for non-vascular complications following renal transplantation. PATIENTS AND METHODS: A total of 30 patients who underwent percutaneous radiological treatment between March 2014 and July 2016 were included in the study. RESULTS: Following renal transplantation, a total of 36 percutaneous radiological procedures which includes hydronephrosis secondary to ureteral stricture (n. 15), clinical symptom-producing lymphocele due to pressure (14) and creatinine elevated nondilated grafts (n. 7) after excluding other reasons of creatinine elevation, were performed. Six patients received percutaneous treatment for both ureteral stricture and lymphocele. The patients underwent balloon dilatation and double- J ureteral stent due to ureteral stricture. The mean pre- and post-procedural creatinine levels were 4.36 ± 2.84mg/dL and 2.17 ± 1.24 mg/dL respectively (p=0.004), indicating a significant difference. For lymphocele treatment, sclerosing agents were injected and lymphatic leakage areas were injected with percutaneous glue. The mean pre- and post-procedural creatinine values were 2.97 ± 1.78 mg/dL and 1.75 ± 1.18 respectively (p=0.002), indicating a significant difference. Nephrostomy catheters were placed for patients with elevated creatinine levels and non-dilated collecting system. The mean pre- and post- nephrostomy creatinine levels were 3.55 ± 2.36 mg/dL and 2.57 ± 1.82 mg/dL respectively (p>0.05), indicating no statistically significant difference. CONCLUSION: The results of our study suggest that percutaneous treatment is an effective method for the treatment of non-vascular complications following renal transplantation, and, therefore, should be the first option for the preservation of graft functions. KEY WORDS: Percutaneous treatment, Renal transplantation.

RESUMO

AIM: To describe a patient with lumbar angiolipoma mimicking schwannoma in the posterolateral side of the spinal canal with expansion of the left lumbar foramen and to discuss the clinical, radiologic, and surgical features of these lesions with literature. METHODS: Without language restriction in this paper, the electronic databases; The Cochrane Collaboration the Cochrane, The Cochrane Library (Issue 2 of 12, Feb. 2011), ProQuest, US National Library of Medicine, National Institutes of Health (NLM) and PubMed dating from 1966 September to January Week 2 2017, were searched for comparative experimental studies using the terms: "OR", "AND". On-line literature searches were conducted using the key words "lumbar angiolipoma", "schwannoma ", "spinal angiolipoma", "spinal cord", and "spinal canal". We compared this research with our patient. RESULTS: Bilateral L2 total laminectomy, excision of the tumors and bilateral L2-L3 transpedicular stabilization were performed, and complaints improved prominently. Pathological examination was reported as angiolipoma. CONCLUSION: The research shows that a probable diagnosis in such tumor cases could be made by sufficient pre-op scanning before surgical operations and although angiolipoma has been rarely seen in lumbar posterolateral space, it can be seen in lumbar region and mimic schwannoma as producing symptoms and signs of spinal cord and nerve root compression.
