BACKGROUND: An intensive and ongoing surveillance program is effective for preventing the hospital infections. but it is time-consuming to detect all cases of hospital infections. So, labratory-based surveillance was performed with the aid of personal computer. The software 'MICRO' that coded and used privately was written in FoxPro 2.0 code. METHODS: All results of the microbiologic culture were stocked in the software and hospital infections were detected by review d an positive microbiology reports and daily ward rounds with examination of patient progress notes. If there was any suggestion or evidence of outbreak of hospital infections the data were analyzed by the 'MICRO' and reported to hospital infections control committee. RESULTS: We detected the outbreak of nosoccmial pneumonia due to a putative single species of methicillin-resistant Staphylococcus aureus in the neurosurgical ward at May, 1996. The suggestive outbreak of wound infections in the 7th ward at April, 1966 was denied by the 'MICRO'. The possible outbreak of 10th ward at May, 1996 was detected. CONCLUSIONS: We describe a surveillance method that identifies excessive rates of positive culture on patient location culture site, and organism indentification using the 'MICRO'. We were able to monitor patient-to-patient cross-infections and possible breakdowns in proper technique, and expect suggestive outbreak of infections early. These results demonstrate that computer analysis of positive culture rates by 'MICRO' is a sensitive and time-efficient method for detecting potentially preventable hospital infections.

Bowens disease is generally regarded as a premalignant dermatosis. If untreated, 3% to 5% of patients may develop squamous cell carcinoma. However, sebaciou carcinoma arising from Bowens disease is very rare. We presented a case of quarnous cell carcinoma and sebaceous circ s disease in a 68 year-old male. He had multiple bowenoid skin lesi nsties. A bean-sized nodule as developed on the bowenoid lesion of the he had a large yellow crust.ed exudative tumor on the Rt. thigh. We took a biopsy specimen of these three discrete lesions. The nu lipid stain of frozen section revealed Bowens disease, squarnous concllnoma arising from Bowen on the trunk and extremi Rt. lower abdomen. Almost of routine histology and carcinoma, and sebaceous carcinoma, respectively.

The muscle glycogen is an important energy source for muscle contraction especially in prolonged exercise. One of the important factors for improvement of physical performance in athletes is the storage of extra-amount of glycogen (supercompensation) in liver and muscles. During 120 minutes treadmill exercise (intensity of exercise was approximatly 80% VO2max), the glycogen concentration was significantly decreased to 36% in liver and 46% in muscles after 60 minutes exercise. At 90 and 120 minutes of exercise, the level of glycogen concentration of liver and muscles statistically were not different from the levels of the 60 minutes exercise. The repletions of glycogen in the liver and muscles in overnight fasted control(C) and 120 minutes treadmill exercise(E) groups during l80minutes after glucose ingestion were investigatect. ln the liver, the concentration of glycogen in C and E groups were markdly increased till 120 minutes after zlucose ingestion, hut the levels of concentration at 180 minutes were decreased comparing to the levels of 120 minutes in both groups. In the muscles, the repletion of glycogen at 60, 120 and 180 minutes of C and E groups were significantly increased comparing to 0 minute of respective groups in the soleus and plantaris muscles. In soleus(SOL), the repletion of glycogen in all of the E groups was significantly higher than that of the respective C groups. However, the repletion of glycogen in all of the E groups of plantaris was revealed higher tendency comparing to respective C groups. Mean repletion rates of glycogen in liver and muscles after glucose ingestion were highest during the first 60 minutes in all groups and the rates of E groups were 2-3 times than those of respective C groups. These results suggest that the glycogen supercompensation in the muscle be provided with decrement of glycogen concentration by exercise, increment of glucose uptake by muscuiar contraction itself and increased insuJin level, and the activation of glycogen synthetase by insulin.

The refractive effects of incision parameters on surgically induced astigmatism in sutureless cataract surgery were studied retrospectively by automatic keratometeric evaluation. 215 eyes undergoing phacoemulsification and posterior chamber intraocular lens implantation were divided into five groups according to the incision length, direction and location : group 1 (14 eyes), 3.5mm superior scleral incision : group 2 937 eyes), 3.2mm temporal clear corneal incision : group 3 (24 eyes), 3.2mm temporal scleral incison : group 4 (24 eyes), 5.5mm superior scleral incision : group 5 (116 eyes), 5.5mm temporal scleral incision. All eyes were examined by keratometry preoperatively as well as at 1 days, at 1 and 2 weeks and at 1 and 2 months after surgery. Cravys vector analysis was performed to calculate the surgically induced astigmatism and keratometric readings were converted to polar values to estimate the mean postoperative keratometric astigmatism. After two postoperative months, mean induced atigmatism was -0.37+/-0.36D in Group 1, 0.27+/-0.44D in Group 2, 0+/-0.33D in Group 3, -0.74+/-0.46D in Group 4 and 0.22+/-0.63D in Group 5. There fore we constructed our own nomogram for managing astigmatism at cataract surgery.

In order to investigate the clinical results of clear lens extraction for high myopia, the effects of 5.5mm sutureless corneoscleral procedure with low power IOL insertion on 21 patients (31 eyes) who were followed up averagely for 9.43 months were analyzed retrospectively. Prophylactic retinal treatment with argon laser was performed in 23 eyes to prevent retinal detachment. Eighty-seven percent (25/31 eyes) of eyes were within +/-1D of targeted refractive error and all eyes were within +/-2D of targeted refractive error. The postoperative corrected visual acuities were increased in 96.8% (30/31 eyes) and 80.7% (25/31 eyes) among them gained two or more lines. the corrected visual acuity of 20/40 or better were increased from 35.5%(11/31 eyes) preoperatively to 93.6% (29/31 eyes) postoperatively. Posterior capsular opacification was developed in two eyes and YAG laser posterior capsulotomy was performed at 2 and 7 months postoperatively. No retinal break, no cystoid macular edema were developed during the follow up period. In conclusion, the clear lens extraction was effective method for correction of severe high myopia but longer follow-up is needed to evaluate it`s complications.

Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.

Tsutsugamushi disease, an infectious disease by Rickettsia(R.) tsntsugamushi, is characterized by eschar, fever and rash. Eschar caused by chigger bite, is pre sent on 47 94% of patients with documented R. tsutsugamushi. We recently noticed one case of R. tsutsugamushi infection. Patient had fever, heaclache, lymphadenopathy, erythematous maculopapules and eschar. The R. tsu tsugamushi was isolated from serum of the patient. Histopathologic findings of eschar show epidermal ulceration overlying a zone of coagulative necrosis of upper dermis and necrotizing vasculitis. E]ectron microscopic findings of endothelial cells of capillary show rickettsia with cell division.
