We report a case of interruption of the inferior vena cava with azygos/hemiazygos continuation and additional variations of the renal veins, an uncommon developmental anomaly. Magnetic resonance angiography and computed tomography, in association with clinical awareness, can be used to diagnose this entity.

We report the first case, in a 4-month-old girl, of an aneurysmal bone cyst secondary to infantile cartilaginous hamartoma of the rib. Infantile cartilaginous hamartoma of the rib (benign mesenchymoma) is a large, expansile tumour that is characterised by cartilaginous, vascular and primitive-appearing stromal and mesenchymal elements. Most cases are diagnosed at less than 1 year of age and may

Tuberculosis of the trachea and main bronchi is a relatively rare disease seen predominantly in elderly patients. We present a case of a fistula between the right and left main bronchus owing to tuberculosis. We describe the CT and MRI appearances. Tuberculous disease of the trachea and main bronchi is a rare entity, much less commonly encountered than the other

To establish the intrarater and interrater reliability of Wisconsin Gait Scale (WGS) in hemiplegic patients. Repeated-measures reliability study using video data of stroke patients. Rehabilitation department of the university hospital. Nineteen hemiplegic patients with 3-9 months stroke history and two physiatrists and two physical therapists. Video recordings were assessed twice, at an interval of 2 days, by the two physiatrists and two physical therapists. Wisconsin Gait Scale. Internal consistency coefficients for the WGS were excellent; Cronbach scores were 0.91 and 0.94 for the first and third days. Coefficient of Repeatability (CR) for observers' WGS assessments were ranged between 4.23-5.76 and intraclass correlation coefficients for total WGS score were indicated very high interrater reliability at the begining and end, respectively 0.91 and 0.96. Intraclass correlation coefficients for fourteen items of WGS ranged from 0.81 to 1. "Hip hiking at mid-swing", &qu...

Cervical mediastinoscopy (CM) is considered to be the gold standard for evaluating mediastinal lymph nodes. The aim of this study was to determine the diagnostic yield of computed tomography (CT) and CM for detecting enlarged mediastinal lymph nodes in non-malignant pulmonary diseases. We retrospectively investigated the correlation and differentiation between chest CT and CM findings in terms of sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), in 30 patients with granulomatous lung disease diagnosed by CM and isolated enlarged lymph nodes seen on CT scans. Biopsy tissues from the lymph nodes in stations right, 1, 2, 3, 4, and 7, were obtained for pathological examination. The 30 patients comprised 11 men (mean age 47.1 +/- 18.4 years) and 19 women (mean age 44.2 +/- 14.0 years). Radiological examination showed that the diagnostic value of stations 2 and 4 was particularly high. Thus, when CM is used for diagnostic purposes, the small lymph nodes in station 1, obtained by careful dissection of the higher mediastinal region, can be helpful. Generally, there is no absolute consistency between the findings of CM and CT. For this reason, obtaining samples from each station regardless of CT findings is recommended.

Endoplasmic reticulum (ER) stress is a key link between obesity, insulin resistance, and type 2 diabetes. Here, we provide evidence that this mechanistic link can be exploited for therapeutic purposes with orally active chemical chaperones. 4-Phenyl butyric acid and taurine-conjugated ursodeoxycholic acid alleviated ER stress in cells and whole animals. Treatment of obese and diabetic mice with these compounds resulted in normalization of hyperglycemia, restoration of systemic insulin sensitivity, resolution of fatty liver disease, and enhancement of insulin action in liver, muscle, and adipose tissues. Our results demonstrate that chemical chaperones enhance the adaptive capacity of the ER and act as potent antidiabetic modalities with potential application in the treatment of type 2 diabetes.
