The reconstruction of soft tissue defects with open fracture around the knee joint is limited by its unique location. Free tissue transfer is hindered by the selection of the recipient vessel and problems of microsurgery. The arc of rotation, defect size, and location must be taken into consideration in the use of regional muscle transfer such as gastrocnemius. According to Mathes et al, the flap survival can be enhanced by selective division of the dominant segmental pedicles, only a part of which can normally be transposed safely on its minor segmental pedicle. Neovascularization, vascular proliferation, and dilatation have also been produced by the delay procedure using silicone sheets. The authors have used the delay procedures with wrapping of the gracilis or sartorius muscle which enabled distally-based transposition of these muscles. The method showed satisfactory outcome in resurfacing the wound around the knee joint. The indictions for this procedure were defects of moderate size and those difficult to reach with conventional muscle flaps. The flap could reach the upper one-third of the lower leg. Other merits are relative simplicity and reliability without significant extension of hospital stay. The drawbacks are the two operative procedures necessary and the risk of infection due to silicone sheets.

We studied the ultrastructural alteration of glomerular anionic sites in 6 patients with minimal change nephrotic syndrome, 5 patients with membranous glomerulonephritis, 4 patients with focal segmental glomerulosclerosis, and 4 patients with IgA nephropathy by staining with polyethyleneimine (PEI) as a cationic probe. The control study was examined by using a nephrectomy specimen of non-glomerular disease which had no proteinuria. This method seems to selectively stain heparan sulphate in the basement membranes and has been widely used to evaluate changes in basement membrane charge in various human diseases as well as in experimental studies. The anionic sites in the lamina rara interna and lamina densa of normal glomerular basement membrane were always less numerous and less regularly distributed than those in the lamina rara externa. Characteristic common findings in these glomeruli showed a marked decrease of glomerular anionic sites in the regions with immune-complex deposits and normal distribution in the regions with focally those being absorbed and newly forming glomerular basement membrane. They were not detected in the gap of the basement membrane and on the area of the detached overlying epithelium using the PEI method. But the foot process fusion of epithelial cells seems not to influence the loss of anionic sites on the glomerular basement membrane.

In order to investigate the level of lead absorption of lead workers and to evaluate the effect of blood lead on blood zinc protoporphyrin (ZPP) and prevalence of lead related symptoms, 1,782 lead workers(male: 1,506, female: 276) from 8 storage battery industries were studied. Selected variables as indices of lead exposure were blood lead, blood ZPP, and hemoglobin (HB). Fifteen questionnaires of lead related symptoms were provided to all lead workers and filled up by themselves and confirmed by medical doctors. Personal variables such as age, work duration, smoking and drinking habits were also collected. The results were follows : 1. While the mean blood lead of lead workers of all lead companies was 31.0+/-3.0 ug/100ml (male: 31.5+/-2.9 ug/100ml, female: 27.9+/-3.3 ug/100m1), the mean blood ZPP of all lead workers was 66.7+/-4.1 ug/100ml (male: 59.6+/-3.3, female: 105.3+/-3.0 ug/100ml). The mean hemoglobin of male lead workers was 15.7+/-.3 gm/100ml and that of female lead workers was 13.0+/-.3 gm/100ml. 2. The percentage of lead workers whose blood lead was over 60.0 ug/100m1 and 40.0-59.9 ug/100ml was 2.81 % and 19.08 %, respectively. On the other hand, the percentage of lead workers whose blood ZPP was over 150 ug/100ml and 100-149 ug/100ml was 5.89 % and 8.31 %, respectively. 3. The slopes of simple linear regression of blood lead (independent variable) and blood ZPP in female lead workers was significantly steeper than that of male lead workers. The slope of storage battery industries with better working condition in terms of low air concentration of lead were less steeper than those with poor working condition with high mean air concentration of lead. 4. Stepwise multiple regression analysis, using overall symptom prevalence as a dependent variables, blood lead, blood ZPP, hemoglobin, age, work duration, drinking and smoking habits as independent variables, indicated that only drinking habit and age were significantly contributed to the dependent variable.

A combined anterolateral and posterior approach with thoracotomy has been recommended as the traditional surgical approach for the tumors of the thoracic spine. Recently, because of the morbidity associated with open thoracotomy, the thoracoscopically assisted surgical technique was introduced successfully in thoracic spinal surgery. Herein, we report a combined surgical technique for giant cell tumor of the thoracic spine (T10) consisting of bilateral thoracoscopic anterior release of the spine followed by a posterior en bloc spondylectomy and reconstruction by orthopedic surgeons. The thoracoscopic spinal surgery is safe and effective alternative for other open thoracotomic procedures in the approach to the anterior thoracic spine, avoiding the disadvantage inherent to thoracotomy.

Diabetic thoracic radiculopathy is not uncommon, but unfamiliar disease entity complicated by long standing diabetes mellitus. It is characterized by typical distressing sensory disturbances and lancinating pains on abdomen and flanks along the thoracic dermatomes in long-standing diabetic patients, which subsides spontaneously. Diagnosis is made by clinical findings and electrodiagnostic technics and other conditions that can affect thoracic spinal root level should be rulled out. With reviewing some literatures, we present two cases which showed the characteristic features of this disorder.

BACKGROUND: The emergence of metronidazole (MTZ) resistance among Helicobacter pylori (H. pylori) isolates has compromised the efficacy of the triple therapy. Therefore, special attention should be given toward reliable methods for determining the in vitro susceptibility. But susceptibility testing of H. pylori is not yet either standardized or routinely performed. The purpose of this study was to establish more reliable, but simple to perform and cost-effective antimicrobial susceptibility testing method. METHODS: With 135 clinical isolates of H. pylori, antimicrobial susceptibility tests for MTZ and clarithromycin (CLR) were performed by antibiotic gradient method (E test, AB BIODISK, Sweden) and disk diffusion method (disk method), and the results were compared with the reference modified broth microdilution method (broth method). RESULTS: Resistant rates of Korean isolates of H. pylori for MTZ and CLR were 46.2% and 2.2%, respectively. There was 100% agreements between the E test, disk method and the broth method for CLR. For MTZ, however, agreements between the results obtained by the three methods were variable. Between the E test and broth method, the agreements were 85.1% in terms of susceptibility categories, 80.5% between the disk and broth method, and 93.1% between the E test and disk method. CONCLUSIONS: Routine susceptibility testing of H. pylori to MTZ seems to be required in Korea. The broth method is recommended for MTZ until more accurate, simple and practical alternative method become available. For the CLR, the disk method is recommended, because it is reliable, simple, and economical.

Methods: Total 179 normal, asymptomatic Korean men were divided in to three groups (6th, 7th, and 8th decade) according to their age. Standard sagittal spinopelvic parameters, including TK and thoracolumbar kyphosis, were measured and subdivided into the following four segments: A (C7 upper end plate [UEP]–T5 UEP), B (T5 UEP–T10 UEP), C (T10 UEP–T12 lower end plate [LEP]), and D (T12 LEP–L2 LEP). These segments of the three study groups were analyzed. Results: In segment B, the segmental kyphosis of group 3 (20.2°±8.0°) showed a statistically larger value than that of group 1 (15.6°±6.8°) and group 2 (16.7°±8.8°) (p=0.017). In segment C, the segmental kyphosis of group 2 (12.9°±6.5°) and group 3 (12.2°±7.1°) showed statistically larger values than that of group 1 (9.5°±6.2°) (p=0.016). The A and D segments of the three groups were not significantly different. Conclusions Increased TK was observed in the middle (segment B) and lower (segment C) thoracic segments in normal asymptomatic male subjects with age. The results from the natural progression of segmental kyphosis with age would provide baseline reference data to help surgeons choose the optimal point of the upper instrumented vertebra level for preventing proximal junctional kyphosis.

A 22-month-old male infant visited at our hospital with stuporous mentality. Brain CT angiography revealed right M1 aneurysm with subarachnoid hemorrhage and intraventricular hemorrhage. After one month from ictus, aneurysmectomy and neck clipping was done. We report here on an extremely rare case of ruptured intracranial aneurysm under the age of 5 years.
