Seventy-three uncemented total hip arthroplasties in the sixty-four patients were studied as a retrospective manner. Hydroxyapatite and tricalcium-phosphate (HA/TCP Calcicoat) coated titanium fiber-mesh stems were used in forty-eight cases and the identical components but without hydroxyapatite coating were used in the other twenty-five cases. The distribution of the patients in two groups showed no statistically significant differences and the same porous coated hemispherical acetabular components were used in two groups. At the time of two year follow-up after the operation, the mean Harris hip score and the Enghs radiographic assessment score were 95.5 and 19.8, respectively, in the HA/TCP Calcicoat tm group and 94.4 and 19.2, respectively, in the non-coated group. None of these differences were statistically significant. At three months after operation, the frequency of the thigh pain was 8.3% in the HA/TCP Calcicoat tm group and 20% in the non-coated group, which was also not significantly different (p=0.24). There were no revisions in either group. All the femoral components except one among the non-coated group showed stable bony fixation in both groups and no differences in Enghs radiographic assessment criteria were detected between the two groups. There seemed to be a tendency of early pain relief and more endosteal new bone formation in the HA/TCP Calcicoat TM group, which, however, failed to show a statistically significant clinical or radiographic differences. This result is considered as preliminary and longer follow-up should be required to uncover any hidden advantages or disadvantages of the HA/TCP Calcicoat TM coating on titanium fiber-mesh stem.

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or

Background: Fluvastatin is the first entirely synthetic 3-hydroxy-3-methylglutaryl-coenzyme A(HMG-CoA) reductase inhibitor. Clinical data indicate that this agent exhibits the proven efficacy of its class and also has some theoretical advantages in safety for long-term use because of its unique pharmacololgic property consistent with hepatoselectivity(i.e., low systemic exposure). This study is to evaluate efficacy and safety of fluvastatin in hypercholesterolemic patients in Korea. Methods: An open clinical trial with fluvastatin was conducted in 31 subjects who continued to have high blood cholesterol levels of 6.21 mmol/L(240 mg/dl) or greater after 1 month of lipid-lowering diet plus single blind placebo period. Fluvastatin was administered for 8 weeks with the initial dose of 20 mg per day and if serum cholesterol levels did not fall below 5.20 mmol/L(200 mg/dl) after 4 weeks the dose was increased to 40 mg per day for the second 4 weeks. On each visit every 4 weeks they underwent interview and laboratory tests about side effects and tolerability. Results: The mean % changes in plasma total cholesterol and LDL-cholesterol from baseline were

BACKGROUND AND OBJECTIVES: Exophthalmos from Graves' disease can result in visual disturbance and cosmetic deformity. Surgical treatment of this disorder is possible through a transnasal endoscopic approach or transantral approach. We aimed to evaluate the efficacy of the transnasal endoscopic orbital decompression and transantral orbital decompression in the management of dysthyroid orbitopathy. MATERIALS AND METHODS: Transnasal endoscopic orbital decompression or transantral orbital decompression was performed on 25 orbits in 14 patients for treatment of progressive exophthalmos or visual loss. Transantral orbital decompression was performed on seven patients simultaneously. RESULTS: Proptosis was reduced an average of 2.8 mm (range 0.5 to 6 mm) by transnasal endoscopic decompression alone and of 3.5 mm (range 0.5 to 8 mm) by transnasal endoscopic decompression and transantral decompression. In five patients who complained of visual disturbance, visual acuity was improved in three of them, and stationary in two of them postoperatively. Four patients who had no diplopia preoperatively developed diplopia after the decompression. Among them the diplopia was only temporary in three patients and the remaining one was referred to an ophthalmologist for correction of persistent diplopia. CONCLUSION: Orbital decomprerssion can be performed successfully via the transantral and transnasal endoscopic approach without significant complications and external scar.

Several cases of accidental subdural injection have been reported, but only few of them are known to be accidental intradural injection during epidural block. Therefore we would like to report our experience of accidental intradural injection. A 68-year-old female was referred to our pain clinic due to severe metastatic spinal pain. We performed a diagnostic epidural injection at T9/10 interspace under the C-arm guided X-ray view. Unlike the usual process of block, onset was delayed and sensory dermatomes were irregular range. We found out a dense collection of localized radio-opaque contrast media on the reviewed X-ray findings. These are characteristic of intradural injection and clearly different from the narrow wispy bands of contrast in the subdural space.

Since 1970, the group B streptococcus(GBS) has been a significant cause of neonatal sepsis in the West. Two distinct forms of disease occur in neonates. Early-onset disease which occurs within 7 days after birth is characterized by respiratory distress, apnea, shock, pneumonia, and occasionally meningitis. Late onset disease usually occurs at 3-4 weeks of age(ranging from 7 days to 3 months) and presents occult bacteremia or meningitis. The GBS is thought to be a rare causative agent for neonatal sepsis in Korea. Lately, we experience a case of early-onset GBS sepsis who died at 3rd day of life. We present this case with brief review of literatures.

OBJECTIVE: To investigate whether there is a significant effect of growth hormone(GH) treatment with diet and exercise over the diet and exercise alone in obese non-insulin dependent diabetes mellitus(NIDDM). METHOD: Twenty obese NIDDM adults were studied. We measured the body weight, body composition and exercise capacity before and after 12 weeks of treatment program. The subjects were assigned in a double-blind manner either to the diet, aerobic exercise with placebo treatment group(group A) or to the diet, aerobic exercise with GH treatment group(group B) for twenty-week period. Two groups were compared for the demographic data. RESULTS: After 12-weeks of treatment program, each group showed a significant weight loss (group A: 8.54+/-2.29 kg vs group B: 7.14+/-2.99 kg) than before the treatment, however there was no significant weight loss between two groups. After 12-weeks, the fat fraction of body weight loss was significantly higher in group B than group A(0.80+/-0.40%kg versus 0.55+/-0.30%kg). After 12-weeks, the maximal oxygen consumption was similarly increased in both groups(23.75% in the group A versus 29.2% in the group B). After 12-weeks, the peak torque was similarly increased in both groups(9.7% in the group A versus 17.3% in the group B). After 12-weeks, the endurance was similarly increased in both groups(10.1% in the group A versus 8.1% in the group B). CONCLUSION: Both group A and B showed a significant weight loss and resulted in a comparable gain in the muscle strength, endurance, and maximal oxygen consumption. The addition of GH in a low dose to a the calorie-restricted diet and aerobic exercise resulted in a significant fat loss especially around the visceral area.

PURPOSE: We evaluated the usefulness of the in vitro adenosine triphosphate-based chemotherapy response assay (ATP-CRA) for prediction of clinical response to fluorouracil-based adjuvant chemotherapy in stage II colorectal cancer. MATERIALS AND METHODS: Tumor specimens of 86 patients with pathologically confirmed stage II colorectal adenocarcinoma were tested for chemosensitivity to fluorouracil. Chemosensitivity was determined by cell death rate (CDR) of drug-exposed cells, calculated by comparing the intracellular ATP level with that of untreated controls. RESULTS: Among the 86 enrolled patients who underwent radical surgery followed by fluorouracil-based adjuvant chemotherapy, recurrence was found in 11 patients (12.7%). The CDR ≥ 20% group was associated with better disease-free survival than the CDR < 20% group (89.4% vs. 70.1%, p=0.027). Multivariate analysis showed that CDR < 20% and T4 stage were poor prognostic factors for disease-free survival after fluorouracil-based adjuvant chemotherapy. CONCLUSION: In stage II colorectal cancer, the in vitro ATP-CRA may be useful in identifying patients likely to benefit from fluorouracil-based adjuvant chemotherapy.
