PURPOSE: To compare therapeutic outcome of intravitreal bevacizumab in treating macular edema between major and macular branch retinal vein occlusion (BRVO). METHODS: This retrospective, observational study included 58 eyes from 58 patients with macular edema secondary to BRVO. All patients were treated with intravitreal bevacizumab injection at baseline, followed by further injections as required with monthly follow-up. Central foveal thickness and best-corrected visual acuity (BCVA) were evaluated after treatment between major and macular BRVO during 12 months of follow-up. RESULTS: The mean best-corrected visual acuity (BCVA) in the major BRVO group (39 eyes), expressed as the logarithm of the minimum angle of resolution (logMAR), decreased from 0.66 ± 0.47 to 0.34 ± 0.28 after 12 months of treatment (p = 0.011). Similarly, in the macular BRVO group (19 eyes), the BCVA decreased from 0.60 ± 0.41 to 0.30 ± 0.22 (p = 0.014). The central foveal thickness decreased in the major BRVO group from 498.5 ± 194.3 µm to 311.3 ± 178.5 µm and in the macular BRVO group from 442.4 ± 155.8 µm to 297.2 ± 145.7 µm (p = 0.004 and 0.002, respectively). However, there was no significant difference between the groups with regard to either BCVA improvement or decrease in central foveal thickness. The mean injection number of macular BRVO (2.6 ± 1.6) was significantly lower than that of major BRVO (3.5 ± 1.4, p = 0.021). CONCLUSIONS: The visual acuity improvement achieved after 12 months of intravitreal bevacizumab injection did not differ significantly between major and macular BRVO. However, significantly fewer injections were required for macular BRVO than major BRVO.

A 6-month-old female infant pre~sented with multiple, slightly depressed pea-sized erythematous macules on. the abdomen and the chest since birth, which together with obese, short stature, short neck, and round face suggested Albrights hereditary osteodystrophy(AHO). Some of the lesions were palpable as hard nodules or plaques in deep dermis. After 3 months follow up, the erythem- atous hue faded out, subcutaneous nodules and plaques enlarged. Skin biopsy specirnen demonstrated a bone formation in deep dermis. Serum calcium and phosphorus levels were lower and upper normal ranges, respectively and serum parathyroid hormone was increased in 69.1 pg/ml (normal, 9-55pg/ml). As pseudohypoparathyroidism including this case mostly exhibit characteristic morphologic features of AHO, the subcutaneous ossification may be a presenting feature.

BACKGROUND: During the last three decades, the resistance of S. pneumoniae to penicillin has been rapidly increasing in many parts of the world, especially in Korea. To characterize the clinical features and epidemiology of penicillin-resistant S. pneumoniae (PRSP) infections in the community and hospital, as well as to investigate the possible spread of resistant clone, we performed the antimicrobial susceptibility tests, pulsed filed gel electrophoresis (PFGE) and penicillin-binding protein (PBP) profile analysis of PRSP isolates. METHODS: A total 48 PRSP isolates from patients who visited or were admitted to Korea University Guro hospital during the period form July 1998 to June 1999 were studied. Anitimicrobial susceptibility tests for 48 isolates were performed with microbroth dilution method to determine the minimal inhibitory concentration of 11 antibiotics. 39 isolates and 35 isolates were subjected to PFGE and PBP profile analysis, respectively to investigate the genetic relatedness between PRSP isolates. RESULTS: Pneumonia was most common site of infection in the community and the hospital as 50%. There were no significant differences of clinical features and prognosis between community and hospital isolates. But, patients with serious underlying diseases had poor prognosis despite of acquisition site. High level penicillin resistance were observed in 69%, multi-drug resistance were 64.6% of isolates. PFGE showed that 13 of 29 community acquired infection were identical PFGE pattern but not that of 23F Spanish clone. There were various PFGE patterns were observed from community and hospital acquired infection isolates. Some of them were existed in both. PBP profiles showed more diverse, even if in isoaltes of the same PFGE pattern. CONCLUSOIN: In our study, high level penicillin resistance and multi-drug resistance were observed in PRSP clinical isolates. No clinical and prognostic differeces were observed between community and hospital acquired infections. Molecular epidemiology study were suggest the there were various genotypes of PRSP within our society. Some of them were observed in the hospital and community. Therefore, there was an evidence of communication of PRSP clones between the community and hospital.

PURPOSE: The purpose of this study was to compare two bowel preparation agents, sodium phosphate solution with magnesium citrate solution. MATERIALS AND METHODS: A total of 94 subjects that underwent a double-contrast barium enema were included in this study. Bowel preparation before performing the barium study was done by using a sodium phosphate solution in 47 subjects and by using a magnesium citrate solution in the other 47subjects. We evaluated the presence or absence of side effects when using these bowel preparation agents. Two radiologist who were blinded to the type of bowel preparation evaluated the quality of bowel preparation at the colonic segments (ascending, descending, and sigmoid colon) on the radiographs obtained by double-contrast barium enema, with regard to stool cleansing, water retention, barium coating and bubble formation. RESULTS: The side effects, such as abdominal clamping pain, nausea, hunger pain and chill occurred more frequently in the sodium phosphate group than in the magnesium citrate group (p<0.001). Stool retention was more frequently found in the magnesium citrate group (p<0.001). However, no statistical difference was noted on the status of water retention and barium coating between two groups. Gas bubble formation was more commonly seen in the sodium phosphate group (p<0.001). The sodium phosphate solution appeared to be more effective in cleansing the right colon (p=0.001). CONCLUSION: Sodium phosphate solution appears to be more effective for colonic cleansing, with a lower incidence of side effects, than when using magnesium citrate solution.

In this study, we report that the treatment of strychinine (STR), an inhibitor of glycine receptor, induced premature onset of programmed cell death (PCD) of developing chick motoneurons (MNs). Treatment of STR on E4 chick embryo increased the apoptosis of MN on E5 when MN PCD does not occur normally. On the other hand, treatment of STR from E3 or E5 for 24 hours did not significantly influence the extent of MN PCD, indicating that the STR effect is developmental stage-specific. However, the expression of glycine receptor isoform was low on E3-4, and other glycine receptor antagonists did not exhibit PCD-promoting activity, suggesting that the STR action on PCD is not related to the glycine receptor activation. Identification of the target molecule for STR action may provide novel mechanism how the onset of developmental PCD is regulated.

BACKGROUND: There have been numerous methods to treat androgenetic alopecia but few methods to treat it effectively and permanently. OBJECTIVE: The purpose of this study was to evaluate bundle hair grafting as an effective treatment for patients with androgenetic alopecia. METHODS: Bundle hair grafiing was performed on 52 patients with androgenetic alopecia who had visited the department of dermatology, Kyungpook National University Hospital and Fatima Hospital. Questionaires regarding cosmetic satisfaction, side effects and general efficacy were recorded by patients themselves one year after hair grafting. RESULTS: The results are as follows : 1. The loss of transplanted hair was most common during the third week(48.1%) after hair grafting. 2. The regrowth of the hair on the recipient site was most common during the 4th month(59.6 %) after the hair graft. 3. Bundle grafting afforded excellent cosmetic satisfaction even after one session in the alopecic area, 4. Facial edema, temporary sensory loss on the donor site, folliculitis and small pitted scarring were seen 19.2%, 5.8%, 1.9% and 3.8% of patients, respectively. 5. The disadvantages were the time necessary to carry out the procedure and the need for an experienced operator and assistants. CONCLUSION: We concluded that bundle hair grafting was an effective and safe therapeutic method for patients with androgenetic alopecia.

BACKGROUND: The appropriate usage of antibiotics needs informations such as its effectiveness for a given infection, administration route, the amount of effective dose, and the dose intervals. In this study, in order to find any significant discrepancy regarding to the details of explanation of the necessary information for appropriate antibiotic usages, we compares informations about 51 antibiotics, one from package inserts in Korea and the other from physician's desk reference (PDR) certified by FDA in the United States of America. MATERIALS AND METHODS: Package inserts about antibiotics, only oral or parenteral agent, were perused to collect three categories of data: the recommended dosage, dose interval, and adjustment of dose to indications or the severity of infection. These data available in Korea were compared with 61 antibiotics (32 oral and 29 parenteral agents) cited in PDR. RESULTS: Package inserts for 51 antibiotics were gathered, because the remaining 10 antibiotics in PDR are not domestically commercialized. Among data on antibiotics comparable with those in PDR, 59% (30 cases:15 oral and 15 parenteral agents) suggested the dose similar to that of PDR, 37% (19 cases:8 oral and 11 parenteral agents) recommend less dose, and 4% in only 2 oral agents showed more dose. About half of the drugs recommending lower dosage were imported from Japanese pharmaceutical company, and the recommended doses of these antimicrobial agents were similar to those in Japan. About 59% (30 cases: 15 oral and 15 parenteral agents) directed dose interval or duration similar to those of PDR and 17% (9 parenteral agents) suggested less administration or longer duration. Surprisingly, in contrast to only 6% (3 cases) of PDR, 24% (12 cases:10 oral and 2 parenteral agents) recommended more administration or shorter duration. About 39% (24 cases:13 oral and 7 parenteral agents) revealed no information for dose adjustment commens to indications or the severity of infection. CONCLUSION: This study revealed that many guidelines in Korea recommend lower doses and/or unreasonable dose intervals. In future studies, improved antibiotic usage guidelines should be established based on pharmacokinetic and pharmacodynamic researches, on the aspect of optimal dosage, dose interval, and dose adjustment commensurate to the indications and the severity of the infection.
