OBJECTIVES: To explore the possible effect of an interaction between summertime heat waves and ozone on cardiopulmonary mortality during the 1994 heat wave in Korea. METHODS: The unusually hot summer of 1994 in Korea was defined as the heat wave in this study. We examined the associations of air pollutants with daily cardiopulmonary deaths between 1991-1995, considering the product term of the heat wave and each pollutant, weather and time trends. RESULTS: During the heat wave, while temperatures were uniformly higher than those of other summers, the within-heat-wave difference in mortality paralleled that in the regional ozone levels. In terms of the influence of the heat wave, the results of ozone were different to those of total suspended particles (TSP) and sulfur dioxide (SO2). The ozone association (relative risk (RR) =1.036; 95% confidence interval (CI) = 1.018-1.054) was observed only under heat wave conditions, while the TSP (RR =1.006, 95% CI = 0.999-1.012) and the SO2 (RR =1.018, 95% CI = 1.011-1.024) associations were found under normal weather conditions (per interquartile increase of each pollutant; results of three pollutants model). The ozone association under heat wave was attributable to the statistical interaction between the heat wave and ozone. CONCLUSIONS: These results support the possibility of a biological synergy between the heat wave and ozone, one that is not evident between the heat wave and other major pollutants like particles or SO2.

The accuracy and sensitivity of both direct and indirect immunofluorescence microseopy in diagnosing chronic bullous dermatoses were evaluated and compared in 11 cases of six different disease entities(pemphigus vulgaris, pemphigus vegetans, bullous pemphigoid, linear IgA bullous dermatosis, familial benign chronic pemphigus), which had been diagnosed clinically and by routine histopa thological studies. And the results obtained were as follows: 1) In 4 cases of bullous pemphigod, the direct IF of perilesional skin showed linear deposition of IgG and C2 along basement membrane zone(BMZ), whereas the indirect IF revealed negetive findings. 2) In 2 cases of pemphigus vulgaris, the direct IF showed deposition of IgG and C2 in intercellular substance(ICS) of perilesional epidermal tissue, and the indirect IF revealed auto-antibody to ICS(1:320) in one case. 3) In 2 cases of linear IgA bullous dermatosis, which were diagnosed as dermatitis herpetiformis by clinical and routine hisopathological findings, the direct IF of perilesional and uninvolved skin manifested linear deposition of IgA, IgM, C3 and F along BMZ, However, no immunofluorescence was detected by the indirect IF. 4) In a case of chronic bullous dermatosis of childhood, the direct IF of perilesional skin showed linear deplosition of IgA and IgM along BMZ. 5) In a case of pemphigus vegetans, the direct IF revealed no specific findings, while the inderect IF disclosed auto antibody positive to ICS(1:40). 6) In a case of familial benign chronic permphigus, no immunofluorescence was found by direct IF. These results indicate that both direct and indirect immunofluorescence micros-copy are valuable in diagnosing chronic bullous dermatoses and in understanding their immune pathogenesis.

BACKGROUND: The purpose of this clinical study was to evaluate the Incentive Spirometry (IS) and Deep Breathing Exercises (DBE) to prevent postoperative pulmonary complications after abdominal surgery in patients over 60 years of age. METHODS: We prospectively randomized 90 patients into 1 of 3 groups: the control group (30 patients) received no respiratory treatment, the IS group (30 patients) was treated with incentive spirometry 4 times daily and DBE group (30 patients) carried out deep breathing exercises under supervision for 15 min 4 times daily. ABGA was taken at ward, PR (preop.room), RR (recovery room), POD1 day and POD2 day. Roentgenographic changes observed at 24 h. and 48 h. after surgery. Pulmonary complications were defined as the development of 3 or more of 6 new findings: cough, sputum, dyspnea, chest discomfort, temperature greater than 38oC, pulse rate more than 100 beats/min. RESULTS: PaO2 in the DBE group and IS group at PR were significantly increased than the values at ward, and the values of the PaO2 in the DBE group at RR and POD1 day, and those of IS group at PR and POD2 day were significant higher than those of the control group (p<0.05). The frequency of development of pulmonary complications (43.3% in the control group, 20% in the DBE group, 20% in the IS group) and roentgenographic changes were comparable in the 3 groups (26.7%, 16.7%, 20% respectively). The DBE group showed the different incidence of postoperative pulmonary complications between upper and lower abdominal surgery (upper: lower= 35.7: 6.3%). CONCLUSIONS: We concluded that DBE and IS were effective in preventing postoperative pulmonary complications after abdominal surgery and lower abdominal surgery causes lesser postoperative pulmonary complications than upper abdominal surgery.

An 8-year-old girl had a rice sized erythematous nodule secreting mucoid fluid situated above the right sternoclavicular joint area since birth. Histopathological findings of the lesion revealed predominant mucous acini, serous acini, demilunes of mixed acini and excretory ducts in the deep dermis compatible with salivary gland. Electron microscopic findings revealed a lumen and serous cells containing serous granules and rough endoplasmic reticulurn. Recurrence has not been noted following total excision of the nodule.
