The aim of this study was to investigate and compare histopathological and computerized tomographic (CT) findings of experimental acute sinusitis in an animal model. The noses of five healthy rabbits were inoculated with a gelatin sponge impregnated with a solution containing Staphylococcus aureus, and one healthy rabbit acted as the control. The animals were sacrificed on the tenth day, following the acquisition of paranasal CT scans. Specimens were obtained from the lateral nasal walls, and the ethmoid and maxillary sinuses of the animals for histopathological examination. Histopathological and CT findings were compared. Various degrees of epithelial disorganization, foci of ruptured epithelial cells, and inflammatory cell infiltration in the lamina propria were seen in the histopathological examinations of the five study rabbits, and mucosal thickening and soft tissue density were noted in their CTs. There was no correlation between the histopathological and CT findings. It was shown that CT did not reflect the acute changes in the sinus mucosa. Patients with chronic sinusitis must be evaluated for a chronic process. Computerized tomographic scans should not be obtained in acute sinusitis cases. In this way, both unnecessary radiation exposure and economic waste can be avoided.
Chronic complications are the leading causes of morbidity and mortality in the diabetic population. The intrarenal resistive index (RI) has been reported to be increased in hypertensive subjects with microalbuminuria and limited data is present for diabetic subjects. 101 subjects with Type 2 Diabetes Mellitus were included in the study. We grouped the study population according to the urinary albumin excretion (UAE). Group 1: UAE<30 mg/day (n=36); Group 2: UAE 30-300 mg/day (n: 37); Group 3: UAE>300 mg/day (n: 28). We also grouped the study population according to the intrarenal RI value. Group I consisted of subjects with RI≥0.70 and group II<0.70. The mean intrarenal RI values of patients in group 3 were higher than those of group 1 and group 2 (0.72 vs. 0.69 p=0.048; 0.72 vs. 0.69; p=0.048 respectively). The duration of diabetes, hip circumference, and hs-CRP levels were statistically significantly higher in subjects with intrarenal RI≥0.70 compared to those with intrarenal RI<0.70 (p:<0.001, 0.048 and 0.0148 respectively). Presence of retinopathy and neuropathy was statistically significantly higher in subjects with intrarenal RI≥0.70 compared to those with intrarenal RI<0.70. RI may predict the development of microvascular complications in diabetic subjects.
Even though testicular nonseminomatous germ cell tumors (NSGCTs) usually have a good prognosis and high curability rates, unpredicted complications owing to chemotherapy regimens might complicate the course. Modalities that are commonly used to cure NSGCTs have well-known side effects. Thromboembolism, which is infrequently associated with germ cell tumors and the vascular toxicity of chemotherapeutics, causes morbidity and mortality. We report a young testicular NSGCT patient, without any known underlying risk factor, who experienced an unpredicted cerebrovascular accident after he received cisplatin-based combination chemotherapy.
Introduction: In the present study, we evaluated the effect of transurethral resection of the prostate (TUR-P) on prostatic resistive index (RI) in patients with benign prostatic hyperplasia(BPH). Patients and Methods: Forty BPH patients who were candidates for prostatectomy were prospectively included in the study. Prostatic RI was measured using power Doppler imaging (PDI) before TUR-P. In the postoperative follow-up, all patients were reevaluated with PDI, International Prostate Symptom Score (IPSS) and uroflowmetry. Results: Mean age, IPSS and maximal urine flow rate (Qmax) of the patients was 65.8 ± 7.6 years, 24.6 ± 7.1 and 7.7 ± 3.8 ml/s, respectively. The mean prostatic RI of the patients before TUR-P was 0.79 ± 0.02. Prostatic RI positively correlated with total prostate volume and IPSS (r = 0.57, p = 0.0001, and r = 0.42, p = 0.008, respectively) and negatively correlated with Qmax (r = –0.37, p = 0.029) prior to treatment. After TUR-P, mean IPSS and prostatic RI significantly decreased (6.5 ± 4.3 and 0.68 ± 0.03, respectively; p < 0.05), whereas mean Qmax was increased (15.7 ± 5.7, p < 0.05). Conclusions: Our data demonstrated that prostatic RI of the patients with BPH significantly decreased after TUR-P. We believe that prostatic RI could be a useful parameter for the follow-up of patients who underwent TUR-P.
Background: Joint involvement associated with psoriasis is referred to as psoriatic arthritis. A late diagnosis of psoriatic arthritis may cause a variety of morbidities; therefore, an early diagnosis and treatment of psoriatic arthritis are required. Asymptomatic psoriatic arthritis has been found in 8-70% of patients with psoriasis using imaging techniques. Objective: To investigate joint and enthesis regions by ultrasonography in patients with psoriasis without inflammatory joint symptoms to detect subclinical psoriatic arthritis. Methods: We included 50 psoriasis patients and 30 healthy control subjects without joint complaint in this study. Twelve joint regions of all subjects in each group were examined by ultrasonography. Results: The presence of any pathological ultrasonography finding (30%) was higher but did not significantly differ in psoriasis patients compared with the control group (13.33%; p > 0.05). Conclusion: Although statistically not significant, the pathological ultrasonography findings were approximately twofold more common in patients with psoriasis compared with the control group. Therefore, the development of psoriatic arthritis in patients with psoriasis should be more closely followed.
