PURPOSE: Since its introduction in the mid-1990s, sentinel lymph node biopsy has been rapidly and widely adopted for the axillary staging of clinically node-negative breast cancer patients. However, there is some controversy in the clinical application because of its various identification rates and its false negative rates. The objective of this study was to assess the usefulness of endoscopic sentinel lymph node biopsy (ESNB) and to compare the value of two methods for identification of ESNB using blue dye only or a combination of blue dye and radioisotope. METHODS: This study was carried out in 137 breast cancer patients (bilateral breast cancer, 3 cases) who underwent ESBN, at the Department of Surgery in Soonchunhyang University from May of 2007 to August of 2008. The technique involved the injection of 5 mL of 0.5% indigocarmine or Tc-99m tin colloid into subareolar plexus. The Visiport docked with a telescope was inserted through a low transverse axillary incison (1.0 cm in size) lateral to the pectoralis major. During the dissection, we identified sentinel nodes by following blue-stained lymphatic duct directly into blue-stained lymph nodes. We compared the value of two methods for identification of ESNB using blue dye only or a combination of blue dye and radioactive tracer. RESULTS: The mean number of sentinel nodes was 1.27 (range, 1-4). The identification rate and false negative rate of the sentinel node were 94.3% (132/140) and 6.9% (3/43), respectively. We compared ESNB with using blue dye only (n=77) vs. a combination of blue dye and radioactive tracer (n=63). Sentinel lymph node identification rate were 90.9% (70/77) vs. 98.4% (62/63) (p=0.043). CONCLUSION: The endoscopic technique of sentinel node biopsy can keep better operative visual fields and is less invasive. The combination of blue dye and radioactive tracer was superior to blue dye only for identification rates.

PURPOSE: To compare and analyze intraoperative and postoperative complications of corneal flap in the LASIK procedures using different types of manual microkeratomes (MLK, LSK, disposable Barron). METHODS: Eight hundred sixty-two eyes were retrospectively evaluated to study the effects of 3 different microkeratomes on the frequency of complications, managements, and postoperative best visual acuity. The eyes were grouped according to the microkeratomes used in making corenal flap: Group 1 (334 eyes) treated with MLK(SCMD, USA); Group 2 (256 eyes), LSK(Moria, France); Group 3 (272 eyes), disposable Barron(Katena, USA). RESULTS: Mean follow-up period was 6.3 months and mean age was 29.2 years (range 20 39). Complications of corneal flap were observed in 74(7.9%) of 862 eyes. Intraoperative flap complications occurred in 15 eyes (4.5%), 6 eyes (2.4%) and 3 eyes (1.2%) in each group, respectively. The postoperative flap complications were observed in 24 eyes (7.2%), 17 eyes (6.7%) and 9 eyes (3.3%) in each group. The postoperative best corrected visual acuity decreased by 2 lines or more in 2 eyes (0.6%), 1 eye (0.4%) and none (0%) of each group. CONCLUSIONS: The incidence of corneal flap-related complications by manual microkeratomes was relatively low. Disposable Barron microkeratome showed the lowest complication rate in our series. It also has an advantage of easy maneuverability, and reproducibility (equal size and thickness of corneal flap).

PURPOSE: To evaluate the outcome of posterior continuous curvilinear capsulorhexis (PCCC) performed simultaneously with cataract surgery to inhibit after-cataract. METHODS: Among patients who underwent phacoemulsification and posterior chamber intraocular lens implantation from December 1999 through December 2001, we had followed on 94 eyes of 80 patients who underwent PCCC intraoperatively and 100 eyes in 92 patients without PCCC as control group. Both groups were divided into 4 categories: nonproliferative diabetic retinopathy(NPDR); uveitis; below 60 years without ocular and systemic disease; over 60 years without ocular and systemic disease. Preoperative and postoperative visual acuity and complications were analyzed from 6 months to 12 months. RESULTS: There was statistically no difference in the best corrected visual acuity at 6 months between PCCC and control group in all categories. Transient increase in the intraocular pressure was noted in 5 eyes (5%) of PCCC group and 3 eyes (3%) in control group. Vitreous prolapse into anterior chamber was found in 2 eyes (2%) of PCCC group. Cystoid macular edema was found in only 1 eye (1%) in NPDR patients of PCCC group. Progression of diabetic retinopathy was found in 1 eye (5.6%) and 3 eyes (12.5%) in each group respectively. There was no statistically significant difference in progression of diabetic retinopathy after surgery between the two groups. CONCLUSIONS: Primary PCCC is a safe procedure to perform in patient who has a predisposition to after-cataract.

BACKGROUND: Neuronal cell death after brain ischemia occurs predominately by necrosis, whereas only a minor fraction of cell death may occur through apoptosis. Authors investigated DNA fragmentation and apoptotic morphology in the brain cell to determine whether apoptosis contributes to the progression of an ischmic lesion. This study was conducted to determine the effects of dexamethasone and hypothermia on moderate brain ischemic injury by middle cerebral artery occlusion (MCAO) in rats. METHODS: Thirty Sprague-Dawley rats (220 - 280 g) were used. Anesthesia was induced and maintained with isoflurane in oxygen. MCAO was induced by intraluminal monofilament nylon. All rats were divided randomly into three groups. In group I (n = 10), normal saline 1 ml was injected intravenously 10 minutes before MCAO. In group II (n = 10), dexamethasone 3 mg/kg was administered and in group III (n = 10), body temperature was maintained at 32degreesC. After 60 minutes of MCAO, all rats that recovered from anesthesia were returned to cages. After 24 hour reperfusion, brain tissue was quickly removed and cerebral hemispheres were separated. Lesion volumes were measured by TTC staining. TUNEL reactivity was examined in the cortical infarction lesion, and rat brain DNA was run on agarose gel electrophoresis to detect DNA fragmentation. RESULTS: Apoptosis and DNA fragmentation in the nucleus developed in the hippocampal area after transient ischemia in rats. Dexamethasone did not prevent the development of apoptosis and DNA fragmentation in transient brain ischemic rats. Moderate hypothermia could prevent the development of apoptosis and DNA fragmentation in transient brain ischemic rat. CONCLUSIONS: Apoptosis may represent a mode of ischemic cell death, and dexamethasone couldn't prevent apoptotic change in the ischemic brain insult. Moderate hypothermia (32degreesC) was a specifically effective procedure to reduce the development of apoptotic change in ischemic insults.

The purpose of this study is to review the clinical and pathological features of pseudomembranous colitis in Korea. Ten cases of psedomembranous colitis, which were diagnosed by sigmoidoscopy and biopsy at the Seoul National University Hospital from May 1982 to occtober 1985, were analyzed in terms of the age and sex distribution, underlying diseases, presumptive causative antimicrobials, symptomatology, involved site and tratment. 1) The disease was more prevalent above sixth decade with a slight preponderance on the female. 2) The underlying diseases of the patients were the uterine cervix cancer in 3 cases and one case each of the nasal polyp, cataract, degenerative arthritis, tuberculous gradmuloma, SLE with menngitis, CVA and gingival abscess. 3) As for the presumptive causative drugs, cephalosporin were assaciated in 6 cases, aminoglycoside m 7 cases, penlcillin in 3 cases, Bactrim in 3 cases, antituberculosis drugs in 1 case and anticancer drugs in 1 case. 4) As for the anatotmical distribution of the lesion, the rectum was involved in 5 cases, the rectum and sigmoid colon in 4 cases and up to the descending colon in 1 case. 5) All the cases were cured by medical treatment. In 5 cases, discontinuation of the antimicrobial drugs and supportive care only were effective and in other 5 cases, vancamycin and/or metronidazole together vrith cholestyramine were added to the regimen.

Thirty nine strains and 109 strains of Shigella sonnei were isolated from the outbreaks of Youngchun and Kyungju, respectively, while 15 strains were isolated from sporadic cases of eight regions in Kyungbuk province from September to November in 1998. We investigated the relationship among the S. sonnei strains by using biochemical characteristics, biotyping, antibiotic resistance pattern, and plasmid profile. Among the isolates, seven strains of S. sonnei isolated in Youngchun showed gelatin hydrolyase positive but the others showed gelatin hydrolyase negative. One hundred and fifty two strains were a type, while eleven among thirty nine strains isolated in Youngchun were g type. Antibiotics resistance patterns of S. sonnei strains isolated in Youngchun and Kyungju were significantly different. Thirty nine strains of S. sonnei isolated in Youngchun were resistant to SM, TE, and TMP/SMX, while eighty six of S. sonnei among one hundred and nine strains isolated in Kyungju were resistant to AM, CB, K, SM, TE, and TMP/SMX. Antibiotics resistance patterns of residual twenty three isolates were similar to those of eighty six strains. The Plasmid profiles of strains of S. sonnei isolated from the Kyungju were different from those of S. sonnei strains isolated in Youngchun. The Plasmid profiles of S. sonnei strains isolated from Youngchun were identical to those of a S. sonnei strains randomly selected from the outbreak in Daegu in 1998. The Plasmid profiles of S. sonnei strains isolated from Kyungju were identical to those of two strains of S. sonnei randomly selected from the outbreaks of Kanglung and Wonju in 1998. From the above results, it is considered that the strains of S. sonnei isolated from Kyungju and Youngchun region are not identical clone.
