This study was conducted to investigate the vibrio flora in sand shrimp, Crangon affinis, which were collected in the estuarine area, Dadaepo near Nakdong River in Korea from in June 1996 to in May 1997. Crangon affinis is very important role in food chain in nature because of food for many seabirds and fishes. Six species of vibrios (Vibrio alginolyticus, V. parahaemolyticus, Listonella damsela (V. damsela), V. harveyi, V. splendidus biotype I, V. splendidus biotype II, and V. natriegens, an unrecorded species in Korea) were isolated from the intestine of shrimps and characterized by the biochemical tests.

A middle-aged female patient showed long-standing multiple or confluent small hyperkeratotic papules on her palms and soles with subsequent development of well differentiated squamous cell carcinoma on the left sole and poorly differentiated pulmonary carcinoma. Arsenic as a possible etiological factor is discussed.

BACKGROUND: Otitis media with effusion(OME) is a very common disease in pediatric age. However, a few literatures on epidemiologic study of otitis media with effusion are available in Korea due to the great variability of its diagnostic criteria and clinical features. The aim of this study is to provide the estimate of silent otitis media prevalence for preschool age. METHODS: The study population includes 329 children enrolled in 6 kindergartens in Kunsan city from April 1 to 10, 1995. Silent otitis media was diagnosed with otoscopy, pneumatic otoscopy and impedance audiometry by DANAC 40 model impedance audiometer from DANA JAPAN Co. RESULTS: The prevalence of silent otitis media with effusion was 14.5% and peak at 6 years of age(17.8%).The prevalence of silent otitis media with effusion according to sex were 11.8% in boys group, 17.9% in girls group. Nine cases(11.8%) involved bilaterally. Forty three cases(89.6 %) were asymptomatic cases. CONCLUSIONS: Among 329 preschool children, the prevalence of silent otitis media with effusion was 14.5%. The prevalence by sex showed slightly higher in girls group than boys group. OME involved unilateral site mostly and subjective symptoms were rare.

This study was conducted to investigate the vibrio flora in edible shellfish (Ruditapes philippinarum, Scapharca broughtonii, Batillus cornutus and Mytilus coruscus) which were purchased from seafood-market or collected from shellfish culture bed in Pusan and Masan Bay from May to October 1997. Sixty-three vibrio strains were identified among 438 collected strains. Five species of vibrios [V. alginolyticus (22 strains), V. parahaemolyticus (35 strains), V. costicola (2 strains), L. damsela (V. damsela 2 strains), and V. cholerae non-Ol (2 strains)] were identified by their phenotyfic and biochemical characteristics. Four groups (142 strains) were identified as genus Vibrio by their biological characteristics, but they could not be identified to the species level.

PURPOSE: To compare the effect of femtosecond laser-assisted cataract surgery with conventional cataract surgery on effective phacoemulsification time (EPT). METHODS: This study included 66 patients 100 eyes who underwent femtosecond laser-assisted cataract surgery and 68 patients 100 eyes who underwent conventional cataract surgery. Both groups underwent phacoemulsification using pulsed ultrasound energy and EPT was evaluated. The groups were further analyzed according to preoperative Lens opacities classification system (LOCS) III grading. Patients who had femtosecond laser-assisted cataract surgery underwent lens fragmentation with quadrant, hybrid, or grid pattern and the EPT was respectively evaluated. RESULTS: The mean EPT was 5.85 +/- 4.31 seconds in the femtosecond laser-assisted cataract surgery group and 10.34 +/- 6.61 seconds in the conventional group. Overall, EPT was statistically significantly lower in the femtosecond laser-assisted cataract surgery group compared to the conventional group. When the groups were analyzed according to LOCS III grading, this result was consistent for all cataract grades and the reduction in EPT was increased with the higher LOCS III grade. When the groups were analyzed according to lens fragmentation patterns, the mean EPT was lower with 350 microm grid pattern than the quadrant or hybrid pattern. CONCLUSIONS: The femtosecond laser-assisted system in cataract surgery can be an efficient cataract surgery using lower EPT compared to the conventional procedure. Additionally, significant differences were observed in the mean EPT of cataract surgery using the femtosecond laser-assisted system among the 3 lens fragmentation pattern groups.
