Results showed that middle-and older-age women were more apt to have CTS than men, and that the dominant hand was more frequently affected. Hormonal changes , repetitive and forceful movements, awkward positions of hand and wrist, and other factors may be associated with CTS. Typical clinical manifestations include pain and paresthesia in the median nerve territory, worsening at night or in the early morning , and being relieved by shaking the hand. Although the patients may localize the discomfort beyond the territory, sensory changes are variable and not entirely reliable. Conduction abnormalities often appeared selectively in the median nerve distal to the wrist in CTS. If the patient who is clinically suggestive of CTS shows normal conduction with conventional methods, palmar stimulation and inching technique is recommended. The diagnosis of CTS requires confirmation of illness history, symptoms and signs with objective electrodiagnostic tests.展开更多

HCV infection is emerging as a metabolic disease, and diabetes mellitus as a risk factor for HCV infection. However, some data on the prevalence of antibodies to HCV in patients with diabetes are conflicting. These seroprevalence data should be interpreted with caution. Some potential bias may occur in those clinic-based studies that target a specif ic disease group. In this letter we explain some reasons for these conflicting studies.展开更多
