RESUMO
OBJECTIVE: To compare the effects of lumbar stabilization exercises and lumbar dynamic strengthening exercises on the maximal isometric strength of the lumbar extensors, pain severity and functional disability in patients with chronic low back pain (LBP). METHODS: Patients suffering nonspecific LBP for more than 3 months were included prospectively and randomized into lumbar stabilization exercise group (n=11) or lumbar dynamic strengthening exercise group (n=10). Exercises were performed for 1 hour, twice weekly, for 8 weeks. The strength of the lumbar extensors was measured at various angles ranging from 0degrees to 72degrees at intervals of 12degrees, using a MedX. The visual analog scale (VAS) and the Oswestry Low Back Pain Disability Questionnaire (ODQ) were used to measure the severity of LBP and functional disability before and after the exercise. RESULTS: Compared with the baseline, lumbar extension strength at all angles improved significantly in both groups after 8 weeks. The improvements were significantly greater in the lumbar stabilization exercise group at 0degrees and 12degrees of lumbar flexion. VAS decreased significantly after treatment; however, the changes were not significantly different between the groups. ODQ scores improved significantly in the stabilization exercise group only. CONCLUSION: Both lumbar stabilization and dynamic strengthening exercise strengthened the lumbar extensors and reduced LBP. However, the lumbar stabilization exercise was more effective in lumbar extensor strengthening and functional improvement in patients with nonspecific chronic LBP.

Castleman's disease is characterized by a massive growth of lymphoid tissue. Since first report in 1956, multiple terms have been used to describe Castleman's disease, including lymph nodal harmatoma, angiofollicullar lymph node hyperplasia, benign giant lymphoma and giant lymph node hyperplasia. Castleman's disease is rare and poor by understood and the optimal therapy is unknown. There are two basic pathologic types in Castleman's disease: Hyaline-vascular type and plasma cell type. Hyaline- vascular type tends to be asymptomatic and is more common in the localized form. Here we report a case of hyaline-vascular type Castleman's disease in retroperitoneum and review previous reports.

Priapism is usually classified into two types, high flow and low flow, by the intracavernosal blood gas analysis. These two types of priapism is categorized pathophysiologically and hemodynamically; therefore, different treatments were performed according to the type. We report a case with recurrent idiopathic priapism, which was diagnosed and managed as low flow priapism at first. But finally it changed to a high flow priapism confirmed by blood gas analysis and further duplex ultrasonic study. During treatment, it was very difficult to cure the ocmplicated infection because of the necrosis of the cavernosal tissue.
