We report three cases of rat mite dermatitis caused by Ornithonysus bacoti(Hirst, 1913), commonly referred to it as the tropicalrat mite. The first case, a 26-year old female had multiple pinhead sized vesicles with peripheral erythematous macule on the upper arms. The second case, a 34-year-old femal had multiple variable sized vesicles with erythematous base on the extremeties. The third case, a 43-year old male had multiple erythematous macules and papules with central punctum on the trunl: and extremities. Histopathologic sections from lesions of the first and second patient showed moderate perivascular lymphahistiocytic infiltration intermingled with some eosinophils. Causative mites, Ornithonyssus bacoti, female were collected around the skin lesion in rase 1, from the house dust in case 2 and furniture in case 3.

PURPOSE: Smoking cessation interventions are important because university students are vulnerable to smoking and good health practices during their university lives greatly affects their health status. The purpose of this study is to investigate the factors affecting smoking cessation success among the university students who participated in the 4-week smoking cessation program. METHODS: This study was conducted with 101 university student smokers. To identify the factors affecting the success of smoking cessation, a logistic regression analysis was performed. RESULTS: In Model 1, without the smoking cessation aids variable, when the frequency of face-to-face counseling was greater, the success rate of smoking cessation was 1.70 times higher. In Model 2, including the smoking cessation aids variable, when the nicotine dependence score was higher, the success rate of smoking cessation was 0.72 times lower, and when the number of smoking cessation aids used was greater, the success rate of smoking cessation was 1.40 times higher. CONCLUSION: Smoking cessation aids are essential to increase the success of short-term smoking cessation, and face-to-face counseling and telephone counseling should be provided continuously to maintain long-term smoking cessation.

In this study, caudal anesthesia was performed with 0.25% bupivacaine and 0.25% bupivacaine-1% lidocaine mixtures at the end of operation. Anesthetics were administered randomly with the volume of 0.5 ml/kg, 0.75 ml/kg, 1.0 ml/kg and 1.25 ml/kg individually. The results were as following: 1) The more the volume of loeal anesthetics administered, the higher the spinal dermatome was blocked(P<0.005) and adequate analgesic levels were achieved. Body height classification by under and over 100 cm does not have statistically significant to determined of local anesthetic dosage. 2) Volume of local anesthetic solution required to block a spinal segment and body weight was most correlated to each other. At least 0.75 ml/kg or 1.0 ml/kg of local anesthetics are average amount for adequate pain control of pediatric urologic patients. 3) Only 17(24%) in 70 patients were required additive analgesic during postoperation 24 hours. 4) Local anesthetic volume required to block per a spinal segment was gradually increased with increased age and it markedly increased from 7 years old patients, this results have statistically significant correlationship. 5) The average volume of local anesthetic solution in patients under and over 100 cm in body height were 0.95+/-0.235 ml/spinal segment and 1.576+/-0.443 ml/spinal segment respectively(P< 0.0005). 6) Analgesic duration did not depend on operation site and body height(cm), analgesic duration tend to prolonged a little in patients who had undergone penoscrotal operation. 7) There was no statistical difference in analgesic durations between 0.25% bupivacaine group and 0.25% bupivacaine-1% lidocaine mixture group. With above results, we suggest that caudal analgesia in pediatric urologic patients who had undergone inguinal or penoscrotal operation would be simple, safe and effective method for postoperative pain relief.

The author observed clinical study and response of -interferon treatment of 43 cases of chronic hepatitis who were admitted to Department of Pediatrics Pusan National University College of Medicine during the period of 4 year 6 months from Jenuary, 1988 to Jun, 1992. The results were as follows: 1) Of 43 patients with chronic hepatitis, CPH was 17 cases (39.5%) and CAH was 26 cases (60.5%). 2) Of 43 patients, chronic hepatitis caused by HBV was 37 cases (86.0%) 2 cases were by Wilson's disease, 1 case was by glycogen storage disease and in the 3 cases, the cause was undetermined and CPH by HBV and CAH were 14 cases (82.4%), 23 cases (88.5%) respectively. 3) A peak frequency (46.5%) of chronic hepatitis occurred between 6 to age and male predominated in a propotion of 3.5:1. 4) On the clinical manifestation, jaundice and hepatomegaly was higher frequency on CAH than on CPH. 5) On the laboratory findings, CAH had higher serum ALT and direct bilirubin level than CPH. 6) On effect of -interferon treatment for patients of CAH, serum ALT and AST levels normalized in 81.8% of patients, negative conversion of HBeAg was 38.5%, Anti-HBe serocoversion was 7.7%, negative conversion of HBsAg was 7.7% and the clearnce of HBV-DNA from seum showed 60.0%. 7) The HBeAg seroconversion (28.6%) on children of HBsAg(+) mother showed lower reponse than HBeAg seroconversion (50.0%) of HBsAg(-) mother after -interferon treatment for patients of CAH.

Severe hyperkalemia can induce life threatening cardiac rhythm disturbances, and usually produce classic electrocardiographic (EKG) manifestations. We report a case of severe hyperkalemia in which the EKG did not reveal the expected alterations. The patient was a 57-year-old man with adenocarcinoma of stomach. There were no significant abnormal findings in laboratory analysis, chest X-ray and EKG. His preoperative medications for hypertension consisted of furosemide, amiloride and enalapril. The tests for serum potassium concentration ([K ]) were performed on 20 and 7 days before the operation and the results were 4.5 and 4.9 mEq/l, respectively. Just after induction of anesthesia, we tried the blood gas and electrolyte analysis and the result revealed high [K ] of 8.5 mEq/l, but EKG did not show typical phenotype of hyperkalemia at that time. His intraoperative and postoperative courses were not eventful.

Contrast arteriography and phlebography remain the standard diagnostic techniques for evaluation of peripheral arterial and venous diseases. However, invasive angiographic techniques involve expense, time, discomfort, and potential risks to the patient which preclude their use as routine screening and followup procedures. In order to obtain accurate, objective information to complement the clinical diagnosis of peripheral vascular diseases, many noninvasive diagnostic techniques have recently become available to the clinican. Among these techniques, photoplethysmograph (PPG), strain gauge plethysmograph (SPG), and doppler ultrasound were adopted for our study. Fourty young volunteers were studied as a control group, and twenty peripheral vascular disease patients were studied as a patient group. We obtained average values of PPGa, blood flow, maximum PRT venous reflux folw (MVRF), maximum venous outflow (MVOF), pulse reappearance time (PRT), PRT/2 and pulsatility idex(PI) for control group. Results for patient group were analysed and compared with those of control group. 1. Normal PPGa wave has a steep upslope, a relatively narrow peak, and a dicrotic wave on the downslope which is concave toward the baseline. PPGa reflected skin blood flow sensitively than any other technique. 2. Average forearm blood flow by means of SPG was 5.7±2.0, and that of calf was 3.7±1.4ml/min/100cc tissue. MVOF of forearm was 32.9±10.4, and that of calf was 18.0±7.0ml/min/100cc tissue. Blood flow measurement was not useful for detection of arterial occlusive disease, but MV OF was useful for diagnosis of deep vein thrombosis. 3. PRT, PRT/2, over shooting reaction time by means of SPG have low diagnostic value and PI by means of doppler ultrasound was useful for localization of arterial narrowing or obstruction. 4. Noninvasive diagnostic techniques including PPG, SPG and doppler ultrasound are useful for screening and follow-up procedures in diagnosis of peripheral vascular disease. They are also valuable to supplement angiographic or physical findings.

The value of double contrast arthrography in meniscal lesions was studied in 58 patients with clinical findings suggestive of meniscal lesion. In all cases, arthrotomy was performed and meniscal lesions were found in 52 patients. The arthrographic findings were compared to clinical and operative findings and the following results were obtained. 1. The diagnostic accuracy of arthrography in meniscal lesions was 84.5% 2. The diagnostic accuracy of the clinical findings was 69%, but the accuracy was increased to 91.4% with the aid of arthrographic findings. 3. Arthrography would be unnecessary if the clinical findings highly suggest the meniscal lesion. 4. Arthrography is thought to be a useful diagnostic method for meniscal lesions.
