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.

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.

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.

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.

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.

The value of the bone scan in pyogenic bone and joint infections is demonstrated in patients who had signs and symptoms suggestive of bone or joint infection. Nineteen patients were evaluated with 99m Tc-methylene diphosphonate bone scan and roentgenogram. The diagnosis of acute osteomyelitis was made in eight patients, chronic osteomyelitis in six patients, septic arthritis in three patients and two patients had soft tissue infection only. Seven of the eight patients with acute osteomyelitis had focal increase of radiopharmaceutical uptake in the bone well before the bony change appeared on roentgenogram. Five of six chronic osteomyelitis patients had not only bony change on roentgenogram but also increased radiopharmaceutical uptake of bone. But the remaining one had only the former, and the lesion was interpreted as inactive. In two of three septic arthritis patients, the lesion was in S-I joint and both of them had no abnormality on roentgenogram but had increased uptake of radiopharmaceutical agent in the joint. Two patients with soft tissue infection had no abnormal radiological bony change and no increase of the radiopharmarceutical uptake in bone on bone scan. From the above data, we concluded that bone scan is recommended in the evaluation of the patients with signs and symptoms suggestive of bone or joint infection for the earlier diagnosis and differential diagnosis in acute case and for the determination of the activity and location of the lesion in chronic case.

We have experienced 11 cases of large bony defect that were treated using microsurgery since 1981. Free vascularized bone transplantation was performed in 8 of them, vascularized bone transposition in 2 cases, and free vascularized joint transplantation in the remaining 1 case. The causes of the large bony defect were primary bone tumor (4 cases), congenital pseudoarthrosis (3 cases), open comminuted fracture (2 cases), sequela of osteomyelitis (1 case), and post-traumatic ankylosis of PIP joint of second finger (1 case). As a donor, fibula was used in 8 cases, iliac crest in 1 case, rib in 1 case and in the remaining 1 case, the second M-P joint of foot was transplanted. In 9 of 11 cases, successful result was obtained and 2 cases were failed because of vascular damage following tibial lengthening in one case and infection on the grafted area in the other one. From the above data and review of articles, following conclusions were obtained. 1. Fibula is thought to be the most appropriate donor for the large bony defect in the extremity, especially in lower extremity, but the donor site must be determined according to the anatomical and physilogical condition of the patient. 2. After mechanical lengthening of the extremity, it is recommened to perform the microvascular surgery after sufficient time for the recovery of vascular damage. But further studies are required for the identification of the change in the vascular tissue following stretching and its recovery time. 3. Progression of the ossification in the epiphysis of transplanted iliac crest was observed and this finding proposed us the idea that the epiphyseal plate injury or leg length discrepancy will be able to be treated with free vascularized epiphyseal plate transplantation and the reconstruction of the destroyed joint of growing children will be possible using free vascularized joint transplantation. 4. As the technique become more popular, the free vascularized bone transplantation is being used for the reconstruction of the extremity more frequently, but it seems to be wise to restrict its indication to cases which are impossible to be treated with more simple methods such as vascularized bone transposition or pedicled bone graft.
