The purpose of this study is to evaluate the effectiveness of Ilizarov external fixator in the treatment of difficult tibial fractures. We analyzed 37 cases with closed or open comminuted tibial fractures and unstable segmental fractures, treated with Ilizarov external fixator between August 1993 and August 1997. Among them, 21 cases were treated with simple application of Ilizarov external fixator. A compression of the fracture site (6 cases), translation (2 cases) and internal transportation technique (2 cases) were applied, and bone graft was applied in 5 cases. We obtained bony union in all cases with Ilizarov method except one case converted to intramedullary nailing due to delayed union. The average time required for bone union were 21 weeks in closed fractures, 26.2 weeks in open fractures. The complications developed were as follows; pin irritation in 14 cases, pin tract infection in 9 cases, adjacent joint contracture in 3 cases, delayed union in 1 case and malunion in 1 case. According to Tuckers classification, the results were graded as excellent in 18 cases, good in 14 cases, fair in 3 cases, poor in 2 cases. In conclusion, Ilizarov external fixation is one of the useful treatment option in closed or open comminuted tibial fractures and unstable segmental fractures.

Kimura's disease is a chronic inflammatory condition of unknown cause. It usually appears as a painless nodule in the head and neck region often associated with regional lymphadenopathy, but there have rarely been reports of penile involvement or clinical presentation as an ulcerative plaque. We present a case of Kimura's disease occurring on the penile shaft as an ulcerative plaque in a 44-year-old man. A vesicular eruption had occurred on his penile shaft followed by an ulcerative plaque for 2 months. He had suffered from recurrent regional lymphadenopathy for 15 years and he had also exhibited intermittent eosinophilia. Histopathologic findings revealed diffuse eosinophilic infiltration in the dermis of the skin and eosmophilic abscesses in the lymphoid follicles of the mguinal lymph node. After short-term systemic steroid therapy and local injection of triamcinolone acetonide, the ulcerative plaque was healed.

BACKGROUND: Erythema induratum was first described by Bazin in association with tuberculosis. However, the tuberculous cause of this entity has been questioned by several authors and gradually, the concept of nontiiberculous nodular vasculitis has been accepted OBJECTIVE: The purpose of this study is to document the clinicopathologic features of erythema induratum. METHODS: We investigated clinical and histopathological findings of 31 patient with erythema induratum who showed positive tuberculin hypersensitivity reaction or had active associated tuberculosis. RESULTS: The ages of the 31 patients(M7: F24) ranged from 13 to 66 years(mean 37.1 years). All patients displayed recurrent crops of tender, painful, violaceous noudules or plaques. Most lesions were present on the legs, but they also occurred on the thighs, feet, buttocks, and forearms. The skin lesions evolved for several weeks and healed with scarring and residual pigmentation. Histological examination revealed lobular or septolobular panniculitis with varying cornbinations of granulomatous inflammaticn, primary vasculitis and necrosis in most biopsies. Twenty two patients were treated with isoniazid alone and the remaining 9 patients received combination anti tuberculous treatment. Relapses were encountered in 4 patients who received isoniazid alone or stopped the medicationrgainst medical advice. CONCLUSION: A diagncisis of erythema induratum should be rendered in the presence of relevant clinicopathologic features, strong positive Mantoux test reaction, and good therapeutic response to antituberculous treatme,it. A full course of combination antituberculous therapy is indicated to achieve a cure of the skin lesions of erythema induratum.

The present study was intended to examine the effect of sodium vanadate on contractility of vascular smooth muscle. Aortic ring preparations were made from the rabbit thoracic aorta and endothelial cells were removed from the ring. The contractility of the aortic ring was measured under various conditions. The results were summarized as follows; 1) Sodium vanadate induced contraction of vascular smooth muscle in a dose-dependent fashion. 2) The contractile effects were not blocked by treatments with adrenergic blocking agent(phentolamine) and indomethacin, indicating the direct action of the drug on vascular smooth muscle. 3) In the presence of ouabain, Na(+)-K(+)-ATPase inhibitor, sodium vanadate still increased the contractility of vascular smooth muscle. 4) Treatment with 4.4'-diisothiocyanostilbene-2.2'-disulfonic acid(DIDS) blocked completely the contractile effects of sodium vanadate. 5) In the presence of verapamil, lanthanum and ryanodine, the contractility of the vascular smooth muscle by sodium vanadate was decreased. From the above results. it was suggested that sodium vanadate acts directly on vascular smooth muscle and causes contraction. It was probably due to inhibition of Ca(++)-ATPase in plasma membrane as well as increasing the release of Ca(++) from sarcoplasmic reticulum and Ca(++) influx across the plasma membrane, but not inhibition of Na(+)-K(+)-ATPase.

The weightlifting is a sort of the sport, which has objects to promote the physical condition and to develop the fundamental strength in the adolescent period, but thete been no interests from the view points of sports injuries for weightlifting. So the authors have studied the changes in the lumbosacral region and wrist of the adolescent weightlifters and the results obtained are as follows; 1. The increase in the lumbosacral angle has a statistically significant relationship with the low back pain in the adolescent weightlifters. 2. The ulnar variance shows statistically significant increase than the control group and its increase seems to be a causative factor in developing wrist pain among the adolescent weightlifters.
