Elderly patient with Genu Varus deformity is commonly treated by high tibial valgus osteotomy to unload the stress concentration medially. Most of these procedures were performed by closing wedge osteotomies and that revealed some problems. Most require a fairly large scar and later reoperation for implant removal. The Ilizarov apparatus and Ilizarov's principles of deformity correction seem to offer several advantages over other methods of high tibial osteotomy. With the Ilizarov method, distractional open wedge technique offers a biomechanically sound, predictably accurate, and reproducible method of correcting an extremity's mechanical axis deviation. From December 1991 to December 1993 at the department of orthopaedic surgery, Pusan National University Hospital, 5 patients(7 tibia) underwent the operation of correction of the genu varum using Ilizarov external fixator for osteoarthritis. The results were summarized as follows: l. All case were female, and the Mean age was 58 years old. 2. Preoperative mean varus angle were 20° and postoperative mean valgus angle were 6° at final follow-up. 3. The complication was not detected includes limb length descrepancy. 4. Mean Ilizarov external fixator fixation period was 5 months. 5. The results after average 1 year 1 month of follow-up were as follows: Excellent in 2 cases(29%), Good in 4 cases(57%), Fair in 1 case(14%), Poor in 0 case()%). 6. The early clinical and radiologic results were encouraging, although a longer follow-up period is necessary.

Proliferative myositis is very rare and was first described as a specific entity in 1960 by Kern. Proliferative myositis is a benign reactive condition that appears as a rapidly growing mass in the proximal muscles of the extremities of adults. Proliferative myositis can be confused with sarcoma clinically as well as microscopically. Proliferative myositis is a bizarre, self-limiting fibroblastic proliferation, the presence of very large basophilic cells with vesicular nucleoli and very prominent nucleoli which resemble ganglion cells or rhabdomyoblast, the cause of which is unclear. The symptoms are non-specific and the diagnosis always rests on a histological examination of the tissue. Local excision is curative and recurrence or metastasis has not been reported even when the abnormal tissue has not been completely excised. The authors report a case of Proliferative myositis in a 59-year-old male.

More than half of the cryptococcal infections occur in acquired immune deficiency (AIDS) patients, and more than half of the non-AIDS patients with cryptococcosis are immunocompromised. Most immunocompromised patients have meningoencephalitis at the time of diagnosis. Without the appropriate therapy, this from of the infection is invariably fatal. Death can occur any time from 2 weeks to several years after the onset of symptoms. Pulmonary crytococcosis in immunocompromised patients is usually asymptomatic, but coughing, chest pain, fever, or hemoptysis may occur in immunocompetent patients. Pulmonary cryptococcosis symptoms in immunocompetent patients tend to improve without treatment. Here, we describe the various pulmonary manifestations of cryptococcal pneumoniae in three immunocmpetent patients.

Heterotopic partial liver transplantation(HLT) in the rat is relatively simple method to orthotopic liver transplantation. Addition of mesocaval shunt which diverts almost intestinal blood to systemic circulation provides only splenopancreaticoduodenal blood for the graft. The usefulness of our novel model is first, evaluating the pure effect of pancreaticoduodenal blood to liver regeneration, second, evaluating the contribution of splanchnic viscera to liver reperfusion injury. In the first group (conventional HLT, C-HLT), the thirty percent graft liver was transplanted just below the host liver with whole portal blood input. In the second group(mesocaval shunt added HLT, M-HLT), the superior mesenteric vein was diverted to systemic circulation and portal blood from the spleen-pancreas-duodenum supplied the graft. The graft weight at 2 posttransplant weeks was significantly increased in the C-HLT group compared with the M-HLT group, which suggests pancreatic blood alone is not sufficient to regenerate the partial liver grafts. There was no significant difference in the graft survival between two groups, which implies the influence of intestine to postreperfusion injury is negligible.

The kidneys play a vital role in the maintenance of normal body fluid volumes and in the composition of the extracellular fluid compartments. There are normally more than 2 million functioning glomeruli that regulate total body water and solute concentrations. As renal failure progresses, there is a decrease in the number of functioning nephrons. Chronic renal failure(CRF) is the consequence of a multitude of diseases that cause permanent destruction of the nephron. Azotemia is an elevation in blood urea nitrogen(BUN) and serum creatinine levels subsequent to a decreased glomerular filtration rate(GFR), which results in uremia. This loss of renal function can cause functional and metabolic abnomalities of body. For this problem, oral & maxillofacial surgeons have demanded to routinely treat patients with CRF. However, there has not been a reported case of orthognathic surgery by bilateral sagittal split ramus osteotomy(BSSRO) in patients with CRF, which can cause multiple complications in healthy patients. We report developmental mechanism of complication associated with CRF and preop. and postop. care of orthognathic surgery by BSSRO in ClIII patient with severe chronic renal failure.

STATEMENT OF PROBLEMS: The heat produced during polymerization of polymer-based provisional materials may cause thermal damage to the vital pulp. PURPOSE: This study was performed to evaluate the exotherm reaction of the polymerbased provisional materials during polymerization by differential scanning calorimetry and to compare the temperature changes of different types of resins. MATERIAL AND METHODS: Three dimethacrylate-based materials (Protemp 3 Garant, Luxatemp Plus, Luxatemp Fluorescence) and five monomethacrylate-based material (Snap, Alike, Unifast TRAD, Duralay, Jet) were selected. Temperature changes of polymer-based provisional materials during polymerization in this study were evaluated by D.S.C Q-1000 (TA Instrument, Wilmington, DE, USA). The following three measurements were determined from the temperature versus time plot: (1) peak temperature, (2) time to reach peak temperature, (3) heat capacity. The data were statistically analyzed using one-way ANOVA and multiple comparison Bonferroni test at the significance level of 0.05. RESULTS: The mean peak temperature was 39.5 degrees C (+/- 1.0). The peak temperature of the polymer-based provisional materials decreased in the following order: Duralay > Unifast TRAD, Alike > Jet > Luxatemp Plus, Protemp 3 Garant, Snap, Luxatemp Fluorescence. The mean time to reach peak temperature was 95.95 sec (+/- 64.0). The mean time to reach peak temperature of the polymer-based provisional materials decreased in the following order: Snap, Jet > Duralay > Alike > Unifast TRAD > Luxatemp Plus, Protemp 3 Garant, Luxatemp Fluorescence. The mean heat capacity was 287.2 J/g (+/- 107.68). The heat capacity of the polymer-based provisional materials decreased in the following order: Duralay > TRAD, Jet, Alike > Snap, Luxatemp Fluorescence, Protemp 3 Garant, Luxatemp Plus. CONCLUSION: The heat capacity of materials, determined by D.S.C., is a factor in determining the thermal insulating properties of restorative materials. The peak temperature of PMMA was significantly higher than others (PEMA, dimethacrylate). No significant differences were found among PEMA (Snap) and dimethacrylate (P > 0.05). The time to reach peak temperature was greatest with PEMA, followed by PMMA and dimethacrylate. The heat capacity of PMMA was significantly higher than others (PEMA, dimethacrylate). No significant differences were found among PEMA and dimethacrylate (P>0.05).
