ABSTRACT
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.

We report a case of apical hypertrophic cardiomyopathy combined with acute myocardial infarction and multiple coronary thrombosis. The patient presented with signs and symptoms of acute myocardial infarction, showing ST elevation in the lateral leads and ST depression in anterior chest leads on initial electrocardiogram. The coronary angiogram on admission, multiple thrombosis of distal left anterior descending artery, left circumflex, diagonal and obtuse marginal arteries were found. The present case shows that apical hypertrophic cardiomyopathy can be combined with acute myocardial infarction and multiple coronary thrombosis.

Alfa-interferon(IFN) has become the major therapeutic modality for chronic viral hepatitis. The spectrum of side effects is one of the main drawbacks of this treatment. Alfa-INF is known to lead to neuropsychiatric sym ptoms. Neuropsychiatric toxicity, including cognitive dys function, irritability, personality changes and emotional instability cause interpersonal problems, discontinuation of work and domestic discord. Other more serious IFN- induced signs of neurotoxicity include delirium, depres sion and seizures. The psychiatric side effects fell into three categories: an organic personality syndrome charac terized by irritability, and short temper; an organic affective syndrome marked by extreme emotional lability, depression and tearfulness; and a delirium marked by clouding of consciousness, agitation, paranoia, and suicial potential. These complications are thought to be revers ible with dose reduction or cessation of therapy. There fore it is important that physicians, patients and their families are informed about the potential risk of the emotional and psychiatric disturbances that can occur during alfa-INF therapy. We report three patients who had neuropsychiatric complications during long-term interferon alfa therapy.
