Comparative evaluation of ceftriaxone- and cefotaxime-induced biliary pseudolithiasis or nephrolithiasis: A prospective study in 154 children.

BACKGROUND: Biliary lithiasis, or sludge, and nephrolithiasis have been reported as a possible complication of ceftriaxone therapy. However, no study related to cefotaxime-induced biliary pseudolithiasis or nephrolithiasis was observed in the literature. Therefore, we investigated the comparative formation of biliary pseudolithiasis and nephrolithiasis after cefotaxime and ceftriaxone therapies. METHODS: The patients treated with ceftriaxone or cefotaxime were enrolled during the study period. Ultrasound imaging of the biliary and urinary tract was performed in all patients before and after the treatment. The patients with a positive sonographic finding at the end of treatment were followed up with monthly ultrasonography for 3 months. RESULTS: The present study showed that abnormal biliary sonographic findings were demonstrated in 18 children (20.9%) treated with ceftriaxone, 13 (15.1%) had biliary lithiasis, 5 (5.8%) had biliary sludge and 1 (1.2%) had nephrolithiasis. Abnormal biliary sonographic findings were demonstrated in only four (5.9%) children treated with cefotaxime who had biliary sludge and only one (1.5%) had nephrolithiasis. It was observed that older age was at significantly higher risk of developing biliary sludge or stone formation. Receiver operating characteristic analysis was performed to determine the residual risk and analysis found that 4.5 years was the cut-off value for age. CONCLUSIONS: The present study is unique in the literature for reporting for the first time gall bladder sludge and nephrolithiasis associated with cefotaxime use. Therefore, patients treated with cefotaxime should be monitored for serious complications like patients treated with ceftriaxone. Nevertheless, if third-generation cephalosporin is used, cefotaxime is recommended to be used rather than ceftriaxone.

Blepharophimosis, Ptosis, and Epicanthus Inversus Syndrome: Expanding the Phenotype.

We present a 3-month-old girl who displayed typical clinical characteristics of blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES). She was referred to our clinic with an initial diagnosis of Down syndrome. Clinical features of elevated follicle stimulating hormone and low estradiol levels in the case were diagnosed as BPES syndrome and were consistent with BPES type 2. To date, there are no cases of BPES with cleft palate and cardiomyopathy, suggesting that these novel findings can be part of this condition.

The relation between pelvic varicose veins and lower extremity venous insufficiency in women with chronic pelvic pain.

PURPOSE: To determine the relation between pelvic varicose veins and lower extremity venous insufficiency in women with chronic pelvic pain. METHODS AND MATERIALS: This study was done in Yuzuncu Yil University Faculty of Medicine, Department of Radiology, with patients who were referred for abdominal and pelvic imaging between January 2007 and April 2008. A total of 1029 women with pelvic imaging study were included in the study. The presence of venous dilatations (diameter > 5 mm) in parauterine and paraovarian localizations were accepted as pelvic varicose veins. In all patients, endometrial thickness was measured and lower extremity venous system was examined with Doppler ultrasonography to assess possible associated venous insufficiency. All patients were undergone questionnaire for frequency of delivery, age, and chronic pelvic pain. RESULTS: Pelvic varicose veins were discovered with transabdominal ultrasound and computerized tomography in 56 of 1029 patients. Various degrees of associated lower extremity venous insufficiency were also discovered in 44 of 56 patients (78,6%) with pelvic venous dilatation. Of the 44 patients with lower extremity venous insufficiency, 21 were bilateral, 9 were right-sided, and 14 were left-sided. Endometrial thickness was significantly increased in patients with pelvic venous dilatation. CONCLUSION: The presence of pelvic varicose veins is significantly associated with lower extremity venous insufficiency. Since the diagnosis of lower extremity venous insufficiency plays an important role in deciding the course of treatment, lower extremity Doppler ultrasonography examination would be useful to include in the evaluation of pelvic varicose veins.

The involvement of distinct neural systems in patients with obsessive-compulsive disorder with autogenous and reactive obsessions.

OBJECTIVE: To investigate the regional metabolite abnormalities and changes after treatment in patients with OCD with autogenous and reactive obsessions. METHOD: We assessed right anterior cingulate cortex (ACC) and amygdala-hippocampal region (Am + Hpp) N-acetyl-aspartate (NAA), choline (Cho) and creatine (Cr) concentrations and NAA/Cr and Cho/Cr ratios using single-voxel proton magnetic resonance spectroscopy in 15 patients with autogenous obsessions (OCD-A), 15 patients with reactive obsessions (OCD-R) and 15 healthy controls (HC). Measurements were repeated after 16 weeks of fluoxetine treatment. RESULTS: Baseline ACC NAA/Cr ratios of both OCD groups were significantly lower than HC. OCD-A group had significantly lower baseline NAA/Cr ratios in the Am + Hpp than other groups. These differences were more likely to be explained by higher Cr levels in ACC. We found no significant differences and changes for Cho levels and Cho/Cr ratios between groups and within groups. Significant increase in NAA/Cr ratios of OCD-A group found in the Am + Hpp was more likely to be explained by increased NAA levels. No significant changes were found in ACC NAA/Cr ratios. CONCLUSION: While disturbed energy metabolism in ACC might reflect a common pathology in patients with OCD regardless of symptom dimension, alterations in mesiotemporal lobe are more likely for autogenous obsessions.

The value of diffusion-weighted MRI in the diagnosis of malignant and benign urinary bladder lesions.

OBJECTIVES: To investigate the role of diffusion-weighted MRI (DWI) in the diagnosis of urinary bladder (UB) tumours by means of measuring apparent diffusion coefficient (ADC) values. METHODS: A total of 83 people aged between 18 and 86 years were included in the study: 63 patients with UB pathology (46 malignant, 17 benign) constituted the case group; 20 individuals without any UB pathology constituted the control group. DWI was applied to all individuals. The ADC values were measured based on the tissue of the UB mass entities and normal UB wall in the control group. RESULTS: The mean ADC value in the UB carcinoma group was significantly lower than that in the control group: 1.0684 ± 0.26 × 10(-3) mm(2) s(-1) and 2.010 ± 0.11 × 10(-3) mm(2) s(-1), respectively (p<0.01). There was a significant difference among the mean ADC values of different grades of malignant tumours, corresponding to 0.9185 ± 0.20 mm(2) s(-1) and 1.281 ± 0.18 mm(2) s(-1) in high-grade and low-grade malignant UB carcinomas, respectively (p<0.01). The ADC value in the carcinoma group was significantly lower than that in the benign lesion group: 1.0684 ± 0.26 × 10(-3) mm(2) s(-1) and 1.803 ± 0.19 × 10(-3) mm(2) s(-1), respectively (p<0.01). All 46 malignant lesions displayed a restriction in diffusion; 4 of the 17 benign lesions displayed a mild restriction in diffusion. The sensitivity, specificity and accuracy of DWI in the diagnosis of malignant UB lesions was 100%, 76.5% and 93.65%, respectively. CONCLUSION: DWI can be beneficial in the differentiation of benign and malignant UB lesions, as well as of high-grade and low-grade UB carcinomas, using quantitative ADC measurements.
