Introduction. Carpal tunnel syndrome (CTS) is the most commonly diagnosed entrapment neuropathy of the upper extremity. The objective of this study was to diagnose CTS and to assess its severity using high resolution ultrasound (HRUS) depending on the results of nerve conduction study (NCS). Methods. A prospective cross-sectional study, in which HRUS was performed at 63 wrists of 35 female patients with different severity of CTS (as proved by NCS). Furthermore, 40 healthy volunteers (80 wrists) underwent the same tests as the patients and have been chosen to match the patients in gender, age, and body mass index (BMI). The cross section area (CSA) of the median nerve (MN) was obtained using HRUS at the carpal tunnel inlet by direct tracing method. Results. There was a significant difference in the CSA of the MN at the tunnel inlet in CTS patients when compared with the control group. In fact, the CSA of the control group showed a significant difference from each of patients subgroups. Furthermore, a significant difference in the CSA was seen in between these subgroups. In conclusion, the US examination of the MN seems to be a promising method in diagnosing and grading of carpal tunnel syndrome.

introduction: Renal trauma is the most common urologic trauma and occurs in 8-10% of patients with significant blunt or penetrating abdominal trauma Aim of study: Is to evaluate role of CT scan as an initial investigation in clinically suspected blunt renal injuries. patient and method: A prospective study was carried out in Al-Sadir medical city in Al-Najaf Al-Ashraf health directorate-Iraq over a period of one year from 1/10/2009 to 1/10/2010, on 53 patients with blunt abdominal trauma admitted to the casualty and referred for radiological assessment, all cases were examined by a specialized radiologist by US then underwent CT examination on basis of selection according to clinical criteria. Results: It showed majority of blunt trauma cases were young adults male, all cases due to RTAs, most of renal injuries are minor injuries; Right kidney was more vulnerable to trauma than left kidney. No contrast reaction was noticed among the patients, normal CT scan effectively exclude renal injury, no cases were missed, in comparison to U/S which is positive in 85% of cases and falsely negative in 14.3%. Blunt renal injuries were rarely associated with free fluid (only 14.3%).
