The aim of the study is to compare vitamin D status and bone mineral density (BMD) in veiled and unveiled healthy Turkish women of reproductive age. Thirty young to middle-aged volunteer veiled women and 30 age-matched control subjects with western clothing habits were enrolled in the study. The two groups had similar dietary habits, body mass index (BMI) distribution, and gestational history. Physical and laboratory examinations were performed to rule out any disease that could affect bone metabolism. Serum 25-hydroxyvitamin D (25-OHD) levels were measured, and BMD of the spine and hip were investigated by dual energy x-ray absorptiometry (DEXA). The mean age of dressing the veil was 15.7 +/- 6.13 years, and 66.7% of the veiled women claimed that they were not ever exposed to direct sunlight, as they were leading an indoor life. Compared with the control group, veiled women were less educated and physically less active (p < 0.001 and p < 0.05, respectively). 25-OHD levels were positively correlated with exposure to sunlight and negatively correlated with the duration of being veiled. None of the veiled women had vitamin D insufficiency, but their mean 25-OHD concentration (33.1 +/- 16 ng/ml) was significantly lower than that of controls (53.9 +/- 27.3 ng/ml) (p < or = 0.001), and serum alkaline phosphatase (ALP) levels were higher (p < 0.01). Differences in the absolute BMD values at the spine and hip were not statistically significant, but the mean Z value at the lumbar spine was significantly lower in the veiled subjects (p < 0.05). Veiled women have low 25-OHD status, and vitamin D supplementation should strictly be advised to these women for the prevention of osteomalacia and osteoporosis.

Internal biliary fistulas (IBF) are seen rarely. Because the symptoms and signs of IBF are not specific and the diagnosis is not suspected, these patients are commonly investigated with plain abdominal films (PAF), ultrasonography (US), upper gastrointestinal series (UGIS), barium enema (BE), and computed tomography (CT), but not always with endoscopic retrograde cholangiopancreatography (ERCP). The purposes of this article are (a) to attract attention of radiologists to presumptive findings of IBF, so as not to misdiagnose this unsuspected and rare disease, and (b) review of the literature while presenting radiologic features of our cases. Five cases of IBFs in which extrahepatic biliary tree communicating with duodenum (four cases) and colon (one case) are reported. Diagnostic work-up of cases were done by PAF, US, UGIS, BE, and CT. Aerobilia, which cannot be explained using other means, ectopic gallstone and small bowel dilatation, nonvisualization of the gallbladder despite no history of cholecystectomy, and thick-walled shrunken gallbladder adherent to neighboring organs were suggestive findings of IBF in our study. Knowledge of imaging findings suggestive of IBF and a high index of suspicion increase the diagnostic rate of IBFs.

In children, infections involving both the superficial and deep neck spaces are common. Children so affected typically present with fever, neck mass, neck stiffness, and, occasionally, airway compromise. Radiologic modalities used in the evaluation of neck infections include plain lateral neck radiography, ultrasound, computed tomography, and magnetic resonance imaging. All these modalities have proved useful in the treatment of such infections, specifically the decision to perform incision and drainage. The charts of 66 patients-33 with superficial and 33 with deep neck infections-were analyzed with respect to symptoms, signs, computed tomography findings, and need for surgical intervention. Computed tomography was not particularly helpful in superficial neck infections with regard to the decision to perform surgical drainage; however, it did localize and demonstrate the extent of infection. In deep neck infections we found a 92% correlation between computed tomographic evidence of an abscess and surgical confirmation of one. Contrast-enhanced computed tomography remains an excellent tool in the treatment of neck infections in children.

Variations of portal venous branching are common and helical CT is efficacious in identifying these variations.
