Basaloid-squamous carcinoma of the esophagus is rare and similiar to the solid type of adenoid cystic carcinoma of the salivary gland. The origin of this tumor is unknown. The tumor was located in the lower third of the esophagus. The case of basaloid-squamous carcinoma consisted of submucosal tumor showing carcinoma with a basaloid pattern and focal squamous differentiation associated with squamous cell carcinoma or carcinoma in situ of the esophageal mucosa. A few submucosal tumor cells were positive for cytokeratin.

Familial Renign Chronic Femphigus(FRCP) is rare, persistent and vesicobullous genodermatoai. Three casee of FRCP with typical clinical and histapathological findings are reported. The first case of FBCP was 27-year-oId man who had recurrent episodes of grou vesicles and rust with miId pruritue at the posterior neck, in both axillae and in inguinal area for 10 years. The second case was 49-year-old woman with skin lesions of recurrent persistent. vesicles, pustules on the erythematous skin, crust and lichenification on the flexural area of extrimeties, axillae, ingumal and neck area for 10 yeara. The third case was 49-year-old male patient who had recurrent pruritic grouped vesicles with crust on the neck and axillary area. In all three patients, skin eruptions usually began and or aggravated in the spring or summer and tend to heal spontaneously in the autumn and winter and showed positive Nikolsky sign. The only one case of the reported three casea had familiaI history of skin lesions similar to FRCP. Histopat,holag;ic finding of biopsy specimens from the vesicular eruption showed auprabasal vesiculation with acantholysis, lacunae and villi formation in all 3 cases.

Oblique single-plane trochanteric osteotomy, in which an oblique cut is made through the femoral trochanteric area and the bony fragments are rotated at the face of the cut in direct contact with each other, allows simulatenous correction of the femoral neck-shaft angle, femoral anteversion as well as flexion/extension effect. Only approximate methods of calculating the correction effects of this procedure have been introduced. Considering unique spatial orientation of femoral neck, we developed a rigorous method to calculate preoperatively the obliquity of the single-plane osteotomy and the amount of rotation required to achieve the target femoral conformation, through geometric analysis. The correction effect by oblique trochanteric osteotomy on the geometry of proximal femur was dependent not only on the amount of change of the neck-shaft angle and femoral anteversion but also on the preoperative neck-shaft angle and femoral anteversion themselves. The flexion/extesion effect was determined by the direction of the correction and the preoperative neck orientation. Computer graphic simulation study confirmed the validity of this method. A program written in QBASIC was introduced to make this complex calculation method more useful in the clinical practice.

BACKGROUND: Disinfection is essential for the prevention of hospital infection. HICLO-S (Soosan environment Co., Yongin, Korea), one of the electrolyzed oxidized water was recently developed as a disinfectant. This is not costly and does not cause any clinical problems and environmental pollution. We evaluated the disinfective activity of HICLO-S against several clinical isolates of bacteria and yeasts. METHODS: 25 strains of bacteria and two strains of yeast were exposed to HICLO-S (30 & 50 ppm HICLO-S) disinfectant for the various periods (0.5, 1, 2, 4, 8, 10, 15, 20 minutes). After the exposure to HICLO-S disinfectant, 0.01 mL of mixture of microorganisms and HICLO-S was inoculated into brain-heart infusion broth or onto Sabouraud dextrose agar and incubated at 35degrees C for 48hours. RESULTS: All strains of bacteria and yeast were killed within 30 seconds after an exposure to 30 ppm of HICLO-S. All of three strains of spore forming Bacillus subtilis were killed within 4 minutes after an exposure to 30ppm of HICLO-S, but all of three strains were killed within 30 seconds in 50 ppm of HICLO-S. CONCLUSIONS: This study showed that HICLO-S disinfectant was effective for the disinfection of commonly isolated bacteria and yeast from hospital, but less effective against spore-forming bacteria. It may be recommended that HICLO-S should he used for the effective disinfection of skin, instruments and hospital floors.

BACKGROUND: The risk of rubella infection is higher among hospital employees than others because of more exposure to rubella viruses. Because rubella infection during pregnancy can cause congenital rubella syndrome, special preventive measures should be taken for female employees in the hospital. METHODS: 309 employees in Soonchunhyang Kumi Hospital, aged from 18 to 45 years old, were included this study. Rubella IgG antibody was detected by the method of MEIA (microparticle enzyme immunoassay). And non-immunized employees were received by Wister RA 27/3 rubella vaccination and rechecked rubella antibody titers at 2 months later after vaccination. RESULTS: Among 309 subjects, 276(89.3%) were positive for rubella IgG antibody. The overall mean titer of rubella antibody was 72 IU/mL (SD: 67 IU/mL). The rubella antibody in titer decreased gradually with aging. The seroconversion rate after vaccination was 100%(28/28). CONCLUSIONS: The authors recommend that the employees susceptible to rubella or all employees in the hospital should be vaccinated for preventing rubella.

It has been generally believed that the continuous flow of blood characterised by arterial inflow and venous outflow is essential for the survival of flaps. Since Baek et al.(1985) demonstrated the survival of a flap based on only a single vein without arterial inflow, there have been a lot of reports of successful skin flaps that depend on only venous blood flow. The location of pedicle is one of the important factors on the survival of flaps, but there have not been an effective study on the survival rates of venous island flaps according to their location of pedicles. In this study, we compared the survival rates of proximally based venous island flaps with those of distally based ones and attempted to decrease the difference, if any, in the survival rates between them. Distally or proximally based 4x3 cmvenous island flap, whose pedicle was a marginal branch of central vein, was elevated from the auricular cartilage of New Zealand white rabbit. IN the half of 20 rabbits, superoxide dismutase (SOD, 20,000 U/kg) was injected intravenously 30 minutes and 60 minutes after the flap elevation. On the 7th postoperative day, survival areas of the flaps were measured by image analysis system and the vascular network with the flaps were examined by micro fil cast. 40 flaps were divided as follows: proximally based venous flaps, distally based venous flaps, SOD treated proximally based venous flaps, SOD ttreated distally based venous flaps. The results were as follow: 1. The survival rate(79.39+/-9.24%) of the proximally based venous flaps were significantly higher than those(60.79+/-14.10%) of the distally based ones (p< 0.01). 2. SOD improved survival of the flap significantly (p< 0.05), and there was no statistical difference in the survival rates between proximally based venous flaps and SOD treated distally based venous flaps (p = 0.1785). 3. Revascularization was actively developed in the proximally based venous flaps and those flaps treated with SOD, but was minimal in the distally based venous flaps. These results suggested that the vascular pedicle would rather be located proximally than distally in designing the venous island flaps and that SOD treatment may be effective for the enhancement of survival of venous island flaps, especially in distally based ones.
