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.

We report two very rare cases of postoperative acute spinal subdural hematoma (ASSH) and review the literature. ASSH is usually related to trauma or a previous lumbar puncture, and a review of the literature revealed only a few cases of spinal subdural hematomas occurring secondary to an underlying hematological disorder or to an iatrogenic coagulopathy. However, there have been no reports about the occurrence of ASSH as a complication of uneventful spinal surgery. The authors present two cases of postoperative ASSHs after open lumbar microdiscectomy (OLM) and underline the pitfalls in their diagnosis and treatment modalities. Two patients were treated with surgery, which progressed without sequelae, and their preoperative symptoms were resolved. Postoperative ASSH is an extremely rare complication, but precautions for meticulous hemostasis and careful awareness for minimal manipulation of the dura during lumbar surgery should be considered in all patients, even those who do not require multilevel decompressions and/or who have a preoperative coagulopathy.

We reviewed 9 cases of pyogenic spondylodiscitis following percutaneous endoscopic lumbar discectomy (PELD). Microbiologic cultures revealed 6 causative organisms. Five patients were managed conservatively and four were treated surgically. The mean follow-up period was 20.6 months and the average length of hospitalization was 24 days. Radiological evidence of spinal fusion was noted and infection was resolved in all patients. Although PELD is a safe and effective procedure, the possibility of pyogenic spondylodiscitis should always be considered.
