PURPOSE: Displaced medial humeral epicondyle fractures with or without elbow dislocation have been treated with open reduction and fixation using K-wires or screws. The purpose of this study is to evaluate the clinical and radiological outcomes of surgical treatments of medial humeral epicondyle fracture without elbow dislocation according to the fixation methods. MATERIALS AND METHODS: Thirty-one patients who had undergone open reduction and fixation of the displaced medial humeral epicondyle fracture without elbow dislocation were included. Group I consisted of 21 patients who underwent fixation with K-wires, and Group II comprised 10 patients who underwent fixation with cannulated screws. Immediate postoperative, final follow-up and normal anteroposterior radiographs were compared and the clinical outcome was assessed using the final Japanese Orthopaedic Association (JOA) elbow assessment score. RESULTS: On the immediate postoperative radiographs, the distal humeral width in Group II was larger than that in Group I. On the final follow-up radiographs, the epicondylar position in Group I was lower than that in Group II. There was no significant difference in the distal humeral width, epicondylar position and joint space tilt between the immediate postoperative, final follow-up radiographs and the normal side within each group. There was no significant difference in the final JOA score between groups. CONCLUSION: Open reduction followed by K-wire fixation or screw fixation of the displaced medial humeral epicondyle fracture without elbow dislocation in older children and adolescents resulted in improved radiologic outcome and good elbow function in spite of diverse radiologic deformities.

Annexin-1 (ANX1) is a 37 kDa protein that is induced and secreted by glucocorticosteroid hormone. The secreted ANX1 has been believed to exert its function by binding to its putative rnembrane receptor. In this report we demonstrate that ANXl receptor (ANX1R) signal blocks the interleukin-1B (IL-1B) receptor signal pathway in human peripheral blood mononuclear cells (PBMCs). When PBMCs were treated with both IL-1B (100 ng/ml) and PMA (10 ng/ml) in the absence or presence of dexamethasone for 5 days, dexamethasone (100 nM) suppressed lymphocyte proliferation to 24% of the control. However addition of anti-ANX1 polyclonal antibody of 1:200 and 1:1,000 dilution to this system induced recovery of proliferation to 80% and 40%, respectively, when compared to the control. In the mixed lymphocyte reaction, dexamethasone suppressed lymphocyte proliferation to 9% of that of control when stimulated with IL-1B (100 ng/ml) and phorbol myristate acetate (10 ng/ml). Addition of anti-ANX1 polyclonal antibody (1:1,000) to this system also recovered the proliferation to 20% of that of the control system. In the ANX1 receptor induction experiment using flow cytometry, ANX1 receptor expression on lymphocytes, CD4+ T cells, CD8+ T cells and monocytes increased depending on the externally added IL-1B ranging from 10 to 1,000 ng/ml. From these results, it is evident that dexamethasone induces ANX1 secretion into the culture medium and anti-ANX1 polyclonal antibody abolishes the effects of dexamethasone. Furthermore these results imply that extracellular ANX1 exerts its effects by binding to the receptor on the cell membrane and the activated signal(s) of ANX1R block IL-1B receptor signal in the lymphocytes.

Isocyanates are the most significant cause of occupational asthma in our country. To evaluate the prevalence of work-related respiratory symptoms and immunologic sensitization to it, we performed a questionnaire survey, allergy skin test, radioallergosorbent test (RAST) to toluene diisocyanate (TDI)-human serum albumin (HSA) conjugate and methacholine bronchial challenge test on 23 isocyanate-exposed employees and 9 unexposed controls working in a zipper factory. Six employees (26.1%) complained of work-related respiratory symptoms and three symptomatic workers showed significant bronchoconstrictions on TDI-bronchoprovocation test. Three (13%) asymptomatic workers had high specific IgE antibodies to TDI-HSA and none of the TDI-sensitive asthmatic workers had specific IgE antibody. One of the TDI-sensitive asthmatic workers showed a negative result on the initial methacholine bronchial challenge test, but bronchial hyperresponsiveness developed after the TDI challenge. It was suggested that TDI-sensitive asthma was noted in three (13%) of 23 exposed workers and that asymptomatic workers could have high specific IgE antibody. Measurement of the changes in bronchial hyperresponsiveness after the TDI challenge could be helpful to diagnose TDI-sensitive asthma.

A combined anterior and lateral approach to the anterior cervical canal was performed on 2 patients with cervical dumbbell-shaped tumors. The procedure consists of anterior discetomy and ispsilateral uncectomy, and removal of the posterolateral corners and posterior transverse fidges of the upper and lower verterbral bodies at the tumor. In one case of a large tumor in the spinal canal, additional removal of a limited segment from the lateral part of the vertebral body was performed and the bone defect was filled with a T-shaped bone graft. The higest level of the operation was C-2 and the lowes was C-4. The authors believe that any cervical dumbbell-shaped tumor below the C-2 level can be removed via anterolateral approach as long as no more than 3 levels of the spine are involved.

The correlation between muscle glycogen content and physical performance in mice was evaluated by investigating whether an increase in glycogen content in skeletal muscle with insulin administration can improve the physical performance without other effects of exercise. Albino rats(group I) were divided into two groups, i.e., insulin and saline administered group. The former experimental group was treated with protamine zinc insulin(15U/kg/day) subcutaneously for two weeks to increase the content of the muscle glycogen and the latter control group with saline. Mice (group II) were also divided into insulin treated and control groups and both groups were subjected to running exercise on an animal treadmill up to point of exhaustion once every day. After two weeks of insulin treatment, the muscle glycogen content, the maximal running time and the maximal swimming time were measured in non-exercised group I. In group II, after 12 days of insulin and saline administration, the muscle glycogen content, the maximal running time, concentrations of lactate and pyruvate in the blood were measured before and after the maximal exhaustive running. The results were summarized as follows. In group I, the muscle glycogen content, the maximal running time and the maximal swimming time of the insulin administered group were significantly greater of the control groups. In group II, the maximal running time was significantly greater(P < 0.01) in the experimental group than of the control group, while the muscle glycogen content revealed no significant difference between the two groups. On the other hand, lactate concentration and lactate/pyruvate ratios in the blood were significantly lower in the experimental group than those of the control groups. From the above results, it may be concluded that the elevation of muscle glycogen content alone by insulin treatment without any previous physical training can improve physical performance of rats. And insulin was also found to improve physical performance even in experimental animals which had been subjected to a longterm of exercise.
