BackgroundOne of the rare presentations of superior vena cava syndrome is bleeding of "downhill" esophageal varices (DEV) and different approaches have been used to control it. This is a case report whose DEV was eradicated by band ligation for the first time.Case presentationWe report a 42-year-old man who is a known case of Behcet's disease. The patient's first presentation was superior vena cava syndrome due to thrombosis followed by bipolar ulcers and arthralgia. He received warfarin, prednisolone and azathioprine. The clinical course of the patient was complicated by one episode of hematemesis without abdominal pain when the patient's PT was in therapeutic range. After resuscitation and correction of PT with fresh frozen plasma transfusion, upper gastrointestinal endoscopy was done. Prominent varices were seen in the upper third of the esophagus, tapering to the middle part without acute bleeding. Stomach and duodenum were normal. Color ultrasonography evaluation of the portal, hepatic and splenic veins was negative for thrombosis. Band ligation was done and the patient's bleeding did not recur.ConclusionBand ligation is a safe and effective method for controlling DEV bleeding in patients with uncorrectable underlying disorders.

Background: Congenital hypothyroidism (CH) is caused by thyroid dysgenesis and dyshormonogenesis. Evidence suggests the presence of genetic factors in both types of pathogenesis. We investigated whether an increased incidence of thyroid abnormalities could be shown by ultrasonography among first-degree relatives of children with CH. Material and Methods: In this case-control study the presence of both developmental and non-developmental thyroid abnormalities was studied among first-degree relatives of CH patients and healthy children. Assessments included neck ultrasonography and thyroid function tests. The data obtained from parents, siblings and children were compared in the case and control groups. Results: In the case group, 92 patients, 172 parents and 57 siblings, and in the control group, 82 healthy children, 160 parents and 39 siblings were studied. Thyroid developmental abnormalities were more prevalent among parents (3.5 vs. 0%, p = 0.03) and siblings (10.5 vs. 0, p = 0.01) of CH patients than the control group. Non-developmental abnormalities were not significantly different between the case and control groups (17 vs. 13%, p = 0.3). Conclusion: Thyroid developmental abnormalities were more prevalent among parents and siblings of CH patients than the control group, confirming the familial component of this entity.

Background:Breast cancer is among the most common cancers in the world. Ultrasound evaluations of breast have come into attention as an alternative route. Ultrasound features of benign lesions such as fibroadenoma can be overlapping with those in a malignant tumor. Here, we assessed the reports of breast ultrasound in patients with pathologic diagnosis of fibroadenoma.Materials and Methods:We conducted a cross-sectional study and enrolled female patients with confirmed histologic diagnosis of fibroadenoma. Ultrasound studies were performed on the participants to see which sonographic patterns are more frequent in such lesions.Results:In 92 patients with 40.4 ± 9.2 years of age, all participants were classified as stage 4 on Breast Imaging-Reporting and Data System scale. The mean ± standard deviation of size for the lesions was 167.4 ± 101.4 mm2. Upper outer quadrants in the breasts had the most number of lesions. Almost lesions were round with only 2.2% were oval. When assessed for the margin definition, 57.8% were circumscribed. Noncircumscribed masses were reported in 21.7%. About 91.3% of cases were hypoechoic in the ultrasound evaluation. Lobulated masses were in 28.3% of the cases. 8.7% of the masses were spongy whereas 9.8% and 2.2% of them had calcification and heterogenic appearance, respectively.Conclusion:The most frequent features include a hypoechoic mass with a circumscribed border; however, complex presentations that overlap malignant masses are also detectable including noncircumscribed margin, lobulation, presence of a posterior shadow, heterogenicity, and micro calcification.
