ABSTRACT: The study included 38 ulnar nerves in 20 healthy subjects. High-resolution ultrasound and Shear wave elastography were used to evaluate the ulnar nerve at the mid forearm. The mean cross-sectional area of the ulnar nerve was 7.1 mm2. The mean shear elastic modulus of the nerve in the short axis was 27.4 kPa. The mean shear elastic modulus of the nerve in long axis was 24.7 kPa. No statistical relation could be noted between elasticity measurements in long and short axes. The ulnar nerve elastic modulus also showed no correlation with CSA neither in the long axis nor short axis. Age, height, weight, and body mass index showed no correlation with the ulnar elastic modulus in short or long axes. The elastic modulus of the ulnar nerve has been determined in healthy subjects and can serve as a reference for future assessment of compressive neuropathies of the ulnar nerve.

The aim of this study is to compare the distal femoral cartilage thickness of patients with type II diabetes mellitus with those of healthy subjects using ultrasonography. The study comprised 34 patients and 36 healthy subjects. Demographic characteristics of all the participants were recorded. The thickness of the femoral articular cartilage was measured using a 5-18MHzlinearprobe.Measurements were performed bilaterally from three points (intercondylar area, medial condyle, and lateral condyle). No significant difference could be found between patients and healthy subjects. Two demographic characteristics correlated positively with diabetic patients.

Portal hypertension is a common condition in association with chronic liver disease; however, it is rarely caused by vascular shunting from splenic arteriovenous fistula (SAVF). We are presenting a case of non-cirrhotic portal hypertension due to SAVF. This condition is usually seen in multiparity women; however, other causes like trauma or mycotic infection are reported in the literatures with equal gender prevalence. Most of the patients present with gastric and esophageal varices, splenomegaly or upper abdominal pain. Clinical history and examination are the first step for diagnosis followed by ultrasound or contrast enhanced computer tomography. Splenic arteriovenous fistula must be then confirmed by selective celiac or splenic arteriography which is the gold standard tool. The condition is treatable either surgical ligation or intra-arterial embolization. Due to less invasive procedure, the later one is more favorable in unstable patients. Both procedures have been reported to be equally successful in managing SAVF.

Peripheral primitive neuroectodermal tumor (pPNET) is a rare, very aggressive neoplasm that belongs to a small round cell tumor, and most often arises from the chest wall. Here, we report a female case with proven pPNET who was treated in our institution. She presented with a history of left side chest pain, cough, and significant weight loss. Contrast enhanced CT imaging of the chest showed multiple left pleural-based enhancing masses with left diaphragmatic involvement. She underwent chemotherapy followed by tumor debulking through thoracotomy. However, she died of rapid growth from recurrent local tumors 3 months thereafter.
