Seventy cases of moderate to severe hallux valgus deformities were operated by proximal metatarsal chevron osteotomy combined with modified McBride procedures from September 1994 to September 1996. The hallux valgus angle improved from an average of 35.1 degrees to 12.1 degrees postoperatively. The first intermetatarsal angle improved from an average of 15.4 degrees to 7.9 degrees. The position of sesamoids was normalized and the metatarsal bone shortened minimally. Union occurred in 6 weeks. Subjectively, pain was relieved in 95% of the patients, while walking and standing abilities improved in 90%. The shoewear improved in only 60% of the patients, showing less satisfactory results compared to other factors. In terms of complications, two recurrences occured but were treated without repeat surgery. Two malunions and four superficial wound infections occurred. In conclusion, proximal chevron metatarsal osteotomy combined with modified McBride procedures is a reliable operation as regards stability, technical ease, low complications and satisfactory results for moderate to severe Hallux valgus deformities.

We studied the association of nonspecific bronchial hyperresponsiveness with general characteristics, exposure concentration, respiratory symptoms, chest x-ray findings, past histories and pulmonary function. We determined bronchial hyperresponsiveness by methacholine challenge test. And we conducted a respiratory symptom questionnaire and performed spirometry on 111 workers occupationally exposed to isocyanates in various industries. About 21.6% of subjects had bronchial hyperresponsiveness. No significant differences were observed between the hyperresponsive and non-responsive group with respect to age, sex, employment period, height, and smoking histories cough and breathlessness were significantly associated with the bronchial hyperresponsiveness. The hyperresponsive group had more experience of bronchitis and asthma in the past than the non-responsive group. The lower FEV1 and FEV1 % were closely related with bronchial hyperresponsiveness. Bronchial hyperrespoosiveness seems to be associated with some of respiratory symptoms, past histories and pulmonary function parameters in workers exposed to isocyanates.

In contrast to the nodular renal blastema which is defined by nests of primitive metanephric cells after 36 weeks of gestation, the nephroblastomatosis is characterized by neoplastic proliferation of the primitive cells. This lesion is presumed to be closely related to the development of Wilms' tumor. We report a case of bilateral nephroblastomatosis associated with Wilms' tumor in a child. This 4 1/2 year-old girl was admitted because of a 10 cm-sized round mass in the right kidney, and smaller nodules in the left kidney and the lung. After three cycles of chemotherapy and subsequent disappearance of the nodules in the left kidney and lung, she underwent a right nephrectomy and a wedge resection of the left kidney. A round Wilms' tumor mass was seen in the lower pole of the right kidney. Remaining right renal cortex showed multiple, slightly depressed gray-white nodules associated with multiple samll cysts. They were comprised of multifocal subcapsular nests of primitive nephrogenic cells with focal tubular or glomerular differentiation. They resembled fetal renal tissue. In the left kidney, similar nests of primitive cells were also noted. These lesions were interpreted as multifocal perilobar type of nephroblastomatosis.

We experienced two cases of occupational asthma induced by Elk dander in Elk-feeders and confirmed these cases by the bronchial provocation test with Elk dander. Both of them showed dual asthmatic response. They also showed positive reaction to the skin prick test with EIK dander. Now one of them has no asthmatic symptoms at all after complete avoidnce of EIK dander.

The possible causes of Brown-Sequard Syndrome (BSS) have been frequently observed with spinal trauma and extramedullary spinal tumors, but the cervical disc herniation to cause BSS is rare. The authors present five cases of patients who were diagnosed with BSS resulting from cervical disc herniation, and the results of the literature in view of their distinctive symptoms and clinical outcomes. Postoperatively, the patients showed complete or almost complete recovery from their motor and sensory deficits. On the basis of our cases, it is important to diagnose it early by cervical magnetic resonance imaging, especially in the absence of the typical symptoms of cervical disc herniation or other obvious etiology of extremity numbness. Immediate surgical treatment is also essential for a favorable functional neurological recovery.

OBJECTIVE: To evaluate the risk factors that may be responsible for the development of contralateral reherniations from ipsilateral ones after open lumbar microdiscectomy (OLM), and to compare surgical outcomes of revision OLM for contralateral reherniations with those for ipsilateral ones. METHODS: Seventeen patients who underwent revision OLM for contralateral reherniation were enrolled into Group I, and 35 patients who underwent revision OLM for ipsilateral reherniation were enrolled into Group II. Using medical charts and imaging study results, the differences in the clinical and radiological factors were evaluated between the two groups. Clinical outcomes of each group were compared between the two groups. RESULTS: Significant differences were found in the interval to reherniation from initial surgery (33 months for Group I and 18.6 months for Group II, p=0.009), as well as in the incidences of both protruded disc (35.3% for Group I and 8.6% for Group II, p=0.045) and mild disc degeneration (29.4% for Group I and 5.7% for Group II, p=0.031) at initial surgery. On binary multi-logistic regression analysis, significant differences were found in the interval to reherniation (p=0.027, Odds ratio=1.051) and incidence of mild disc degeneration (p=0.025, Odds ratio=12.03) between the two groups. There were no significant differences in the improvement of clinical outcomes after revision OLM between the two groups. CONCLUSION: The interval to reherniation from initial surgery and the grade of disc degeneration at initial surgery were key factors that distinguished the development of contralateral reherniations from ipsilateral ones. Surgical outcomes of revision OLM were similar in both groups.
