BACKGROUND: Mycobacterial culture is a confirmatory test to detect M.tuberculosis, but it takes at least 6 weeks to diagnose. PCR is a rapid and sensitive method, but it is known that PCR has a high false positive rate due to contamination, and a high false negative rate due to inhibitors. It is also known that LCR and PCR-Hybridization, recently developed methods, are more specific methods than PCR in terms of detection M.tuberculosis. In this study, we estimated the clinical utility of in house PCR, LCR and PCR-Hybridization for the detection of M.tuberculosis. METHODS: We evaluated 75 specimens, upon which M.tuberculosis culture based testing was requested, by PCR LCR, and PCR-Hybridization and compared results. Mycobacterial culture was performed on 3% Ogawa media for 8 weeks, and an in house PCR, LCx Mycobacterium tuberculosis assay kit(Abbott Laboratories, North Chicago, III) and the AMPLICOR M.tuberculosis test kit(Roche Molecular Systems, Inc. Branchburg, NJ, USA). RESULTS: In the view of the culture results, the sensitivities of the three tests were 40%, 80%, and 100% and their specificities were 98.6%, 94.3%, and 94.3%. CONCLUSION: LCR and PCR-Hybridization and rapid and sensitive methods for detecting M.tuberculosis in clinical laboratories.

We experienced a case of primary aldosteronism due to adrenal adenoma. The patient was 45-year old female, whose main complaints were weakness, headache, and fatigue. By use of abdominal CT scan, ultrasonogram, adrenal angiogram and by result of clinical laboratory findings, we conculuded the diagnosis of adrenal adenoma, and confirmed it by surgical and pathologucal findigs. The clinical sympyoms disappeared after left adrenalectomy, and laboratory findings of renin, aldosterone, electrolutes were normalized but hypertension persisted, so she has been managed by antihypertensives.

This study was conducted to compare the maternal characteristics, and birth weight of infants delivered at five different categories of medical facility in Taegu to examine the risk level of pregnant women and children by the medical facility for delivery. The study population included 1,410 pregnant women who delivered a baby at one of nine medical facilities (3 university hospitals, 2 general hospitals, 2 private clinics, 1 midwife clinic, 1 MCH center) in Taegu in April, 1987(April and May, 1987 for K university hospital). Pregnant women were interviewed to ask the age and educational level of woman, payment of medical fee, birth order, delivery method. Birth weight of infant was obtained from medical record. Mean ages of the women delivering at the university hospitals(27.5 years) and at general hospitals(26.7 years) were higher than those at midwife clinic(25.4 years) and at MCH center(26.1 years). Also, mean years of school education were higher in women of university hospitals(12.7 years) and general hospitals(12.2 years) than in women of midwife clinic(9.2 years) and MCH center (9.3 years). The percentages of women covered by the medical insurance were far greater in the university hospitals(78.1%) and general hospitals(82.9%) than in private clinics(44.3%), midwife clinic(29.1%) and MCH center (5.4%). Infants born at the MCH center were mostly the second birth (47.3%) while 56.0% to 61.7% of infants born at all the other medical facilities were the first birth more women delivering at the university hospitals had history of spontaneous abortion as well as still birth than the women delivering at the other medical facilities. The preterm birth rate (11.4%) and low birthweight incidence rates(5.8-13.0%) in university hospitals were significantly higher than those of other medical facilities. Accordingly, c-section rates showed a wide variation among the medical facilities. Study findings revealed that most of women delivering at the university hospitals and general hospitals are in the middle of or upper socio-economic class and obstetrically high risk group regardless of socioeconomic class while the women delivering at the midwife clinic and MCH center are low risk group of low socioeconomic class. Therefore, the data of a specific medical facility are highly limited in interpretation and can not be generalized.

Holoprosencephaly(HPE), a common developmental defect affecting the forebrain and cranioface, is etiologically heterogenous. Teratogen, chromosomal anomalies, genetic syndrome, or genetic disorder of non-syndromic HPE are usually accepted as etiology. But the severity of brain and craniofacial malformation are not associated with etiology. Individuals with microform of HPE, who usually have normal cognition and brain imaging, are at the risk of having children with HPE. Several studies on the basis of HPE gene have been performed, which shed valuable insight on normal brain development. As additional HPE genes are identified, more accurate recurrent risk counseling can be given. We experienced a case of recurrent HPE diagnosed by transabdominal ultrasound examinations at 22 weeks' gestation.

PURPOSE: To report two cases of trabeculectomy with biodegradable collagen material conducted on two post-vitrectomy patients. CASE SUMMARY: The first patient was a 43-year-old woman with uncontrolled increased intraocular pressure (IOP) after pars plana vitrectomy with scleral buckling for diabetic retinopathy and vitreous hemorrhage. Another patient, a 28-year-old woman with aphakia, also had uncontrolled increased IOP after pars plana vitrectomy with encircling scleral buckling for retinal detachment. For both of these patients, we performed trabeculectomy using mitomycin C and recently developed biodegradable collagen matrix. In the first case, the IOP was increased three months after the surgery, for which needling was done. After needling, the IOP was well controlled in the range of 16 to 19 mmHg up to eight months postoperatively with stilling anti-glaucomatous eyedrops (Cosopt(R), Xalatan(R)). In the second case, IOPwas increased one week after the surgery, but it was well controlled between 14 to 21 mmHg up to nine months postoperatively with anti-glaucomatous eye drops (Combigan(R)). CONCLUSIONS: Biodegradable collagen matrix can possibly reduce the surgical failure of trabeculectomy and it is especially suitable for high risk patients when combined with anti-metabolic agents like MMC.

A 50-year-old female was referred to our clinic with visual disturbance, hyphema and increased intraocular pressure (IOP) in her right eye 7 days after experiencing blunt trauma in that eye. She had undergone uncomplicated laser in situ keratomileusis (LASIK) on both eyes 10 years earlier. At initial examination, the best corrected visual acuity (BCVA) in her right eye was counting fingers at 2 feet with no correction. Central Goldmann applanation tonometry (GAT) showed an IOP of 7 mm Hg. Peripheral digital tonometry showed the IOPs in her right eye superiorly, nasally, temporally, and inferiorly were 36 mm Hg, 35 mm Hg, 34.5 mm Hg and 36.5 mm Hg, respectively. Slit-lamp examination showed diffuse epithelial and stromal edema and a blood clot 1 mm in height in the anterior chamber. Spectral domain scanning laser ophthalmoscope/optical coherence tomography (SD-SLO/OCT) images showed a pocket of fluid between the LASIK flap and the underlying stroma. The patient was started on anti-inflammatory agent and IOP lowering agents. After 15 days of treatment, IOP measured with GAT was 10 mm Hg, slit-lamp examination showed that epithelial and stromal edema had disappeared, and OCT showed no fluid between the corneal flap and stroma.

PURPOSE: To report a case of optic neuropathy from vitamin B12 deficiency associated with chronic alcoholism and malnutrition. CASE SUMMARY: A 51-year-old man with a complaint of declining visual acuity in both eyes without pain was found to have a temporal optic disc pallor in the left eye. The patient had a history of chronic alcoholism and malnutrition for the previous 7 months. Visual field examination showed central scotoma in both eyes. The vitamin B12 level was undetectable by a blood biochemistry test. Blood dyscrasia such as anemia or thrombocytopenia was not found. The vitamin B12 level became normal after intramuscular cobalamin injections, and visual acuity and visual field tests recovered after 3 months. CONCLUSIONS: Optic neuropathy from vitamin B12 deficiency can be solely present without other systemic manifestations in a patient with chronic alcoholism and malnutrition. Prompt diagnosis by thorough history taking and vitamin B12 supplementation can reverse the disease.

Corticosteroid, 5-fluorouracil and Mitomycin C(MMC) have been used to suppress proliferation of subconjunctival connective tissue. However, the various complication and undesirable side effects associated with the use of these drugs have prompted the search for alternative drugs with less toxicity. In present study, I have evaluated the effect of corticosteroid(dexamethsone sodium phophate), cyclooxygenase inhibitor(diclofenac sodium) and lipoxygenase inhibitor(nordihydroguaratic acid, NDGA) to inhibit human pterygial fibroblast proliferation in tissue culture. Human pterygial fibroblast were cultured and exposed to various concentration of each drug for 1, 2 and 3 days. Cell viability was measured using MTT assay. There was no different in antiproliferative activity between nonsteroidal antiinflammatory agents(NSAIDs) and steroid. Dexamethasone caused inhibition of proliferation with LD 50 of 0.5mM by day 2, NDGA of 0.5mM by day 3 and diclofenac sodium of 1.0mM by day 3. These results suggest that NSAIDs may be useful as both antiproliferative and less toxicity agents.
