OBJECTIVES: This study was performed to evaluate obstetric aspects and epidemiologic data of respiratory distress syndrome(RDS) in premature baby(under 37 gestational weeks). We compared the mortality and incidence of RDS in premature baby according to gestational age, birth weight, infant sex, mode of delivery. In addition, this study was searched for demonstrating the influence of hypertensive mother, and effectiveness of surfactant and corticosteoid administration. METHODS: A study was conducted for 2,360 premature baby under 37gestatinal weeks, who were born at four main hospitals in Kwangju and Chonnam from January 1, 1995 to December 31, 1997. Data were collected from hospital records and was analyzed by SPSS computer program. RESULTS: 1. The total incidence of RDS among all the preterm infants under 37gestational weeks, who were admitted in NICU of four hospitals was 22.7%. 2. Neonatal mortality was decreased as the gestational age and or birth weight advanced. (p<0.001) 3. There was no difference in the incidence of RDS according to sex and mode of delivery. (p>0.005) 4. The mortality of RDS infants in this study was 28.1%. 5. There was no statistical correlation between neonatal mortality and use of surfactant. 6. Corticosteroids administration to preterm mother did not decrease the incidence of RDS, but, there was no statistical significance due to insufficient study group. 7. The incidence of RDS among the babies of hypertensive mother was 21.0%. CONCLUSION: Still the RDS in premature baby is the most common cause of perinatal death in this country. In our study, the incidence and mortality of RDS in prematue baby was mainly depends on gestational age of infants. Therefore, we suggested that prevention of preterm labor is the important to decrease the incidence and mortality of RDS.

In a series of 20 young rats, three cortical lesions were made in each hemisphere. Two of these lesions were filled with avitene and gelfoam, while the third was left empty as a control. The animals were killed successively on weeks 1, 2, 4 and 8 after the operation. The results were as follows : 1) Although there was no difference in the type of tissue reactions, avitene was more rapid and profound than gelfoam in the process and degree of inflammatory reaction at the same periods. 2) Avitene biodegradaded more rapidly than gelfoam. 3) The extent of fibrosis and adhesion to the surrounding brain tissues were not grossly different between these two agents but more profound histopathologically in avitene at the same periods. With these results, we could conclude that the avitene was superior to the gelfoam as the hemostatic agent in neurosurgical area.

In 2008, Korea has enacted new ordinances about the role of estheticians, but this law can be interpreted ambiguously, restricting hiring of estheticians in medical clinics. The purpose of the study is to obtain information about medical-esthetic systems in other countries. We have taken a survey of this object from 30 OECD & Asian countries, and the questionnaires returned from a total of 22 countries (Australia, Austria, Canada, Denmark, Finland, France, Germany, Hungary, Japan, Netherlands, New Zealand, Norway, Portugal, Slovak Republic, Spain, Switzerland, Turkey, United Kingdom, United States, Singapore, Israel, and Thailand), were used for the final analysis. The results are summarized as follows. In most countries, estheticians working independently deal with only healthy, normal skin. In most countries, estheticians working independently have no right to operate any medical instruments. In all 17 countries that returned the questionnaires medical clinics can employ estheticians, and only theses estheticians who belong to the medical clinics can handle the non-invasive medical instruments under the supervision of doctors. In 17 countries that have related legal regulations, nurses, under the control of doctors, can perform wider range of duties in various settings than estheticians. The survey concludes that the duties of estheticians are closely related with medical skin care services and estheticians can perform various non-invasive medical procedures only under the control of doctors. From consulting a variety of medical-esthetic systems in other countries, we propose that the estheticians be allowed to work in medical clinics to provide better medical services for the patients and to make more chances of employment for themselves.

Cutaneous horns of the penis are rare. We report a case associated with squamous cell carcinoma in a 56-year-old male. A gradually enlarging nodule had been on the glans penis for four years. He had suffered from an erythematous crusted tumor mass and horny excrescence on the glans penis which recurred and was aggravated after excision of the nodule seven months ago. Histopathologic findings of the lesions showed characteristic findings of squamous cell carcinoma and cutaneous horn. In situ DNA hybridization for human papillomavirus types 6, 11, 16, 18, 32, and 33 were all negative. The tumor mass were surgically excised and we have not found any sign of recurrence since then.

OBJECTIVE: To investigate the preterm labor & preterm infants care in Kwangju and Chonam. METHODS: A study was conducted for 2,360 newborns who were born at four main hospitals in Kwangju and chonam from January 1, 1995 to December 31, 1997. Data were collected by review of hospital records. RESULTS: 1. The survival rate was 6.90% at 23~34 weeks, 38.60% at 27~28weeks and 90.67% after 31wks. 2. The survival rate divided according to birth weight were 8.89% below 1,000gm, 57.14% in 1,001~1,500gm, 86.75% in 1,501~2,000gm and 93.37% over 2,000gm respectively. 3. Clinical causes of neonatal death were RDS(48.84%) hyperbilirubinemia (20.74%), sepsis(11.95%) and pneumonia(9.67%). 4. Incidence of RDS was 23.22% and it's neonatal mortality was 36.28%. CONCLUSION: The survival rate of preterm birth in Kwang-Ju and Chon-nam was still lower than data from advancing countries, and main cause of neonatal death was respiratory distress syndrome.

BACKGROUND: Propofol is an alternative to thiopental as an intravenous induction agent for cesarean section. It is also used as a sedative for supplementation of regional blockade during cesarean section. It has been reported that propofol relaxes not only vascular smooth muscle but also other smooth muscles. The aim of this study was to investigate the effect of propofol on rat uterine smooth muscle in an isolated preparation in the rat. METHODS: Uterine smooth muscle tissues were obtained from rats (n = 21). The muscle strips were suspended in tissue baths and isometric tension was recorded. After spontaneous or oxytocin induced activity had been accomplished in the buffer solution as a control, propofol (1 to 20microgram/ml) in fat emulsion was applied cumulatively to the bath and the effects were continuously recorded. RESULTS: In vitro, propofol induced a dose-dependent inhibition of spontaneous as well as oxytocin induced myometrial contractile activity. Propofol concentration of 1microgram/ml had no significant effects on the resting tension, active tention, and frequency of contraction developed by spontaneous and oxytocin induced uterine contractility. However, Complete muscular relaxations on spontaneous and oxytocin induced contractility were obtained at a concentration of 10microgram/ml and 20microgram/ml, respectively. CONCLUSIONS: Propofol inhibits spontaneous and oxytocin-induced uterine smooth muscle contractions in dose dependent pattern.

Leukemia cutis are clinically divided into the specific and nonspecific types. The former demon strates a malignant cell infiltrate on histopathologic examination. We report a case of leukemia cutis in a 29-year old female which developed specific cutanous manifestations previous to peripheral blood abnormalities, She had suffered from several discrete, bean to walnut sized, tender, erythematous patches and nodules on the trunk for 3 months and these gradually spread to the right cheek and upper arm. Atypical lymphocytes and incesassed lymphoblasts were notifced on a peripheral blood smear and bone marrow aspiration. A bone marrow biopsy revealed compact marrow finding, and increased celluarity. The histopathlogic findings showed diffuse dermal and subcutaneous infiltration of atypical lymphocytes. An immunohistochemical study with kappa, lamda, and leukocyte common antigen(LCA) revealed lymphoid malignancy, T-cell type. We treated her with various combined chemotherapy for 2 year, but her skin lesions were not inproved.

Kaposi's sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Transplant type. Epidemic or AIDS categories is found approximately 20 % of all AIDS and has strong predilection for head and neck region. The first case of Kaposi's sarcoma observed in patients with kidney transplants was reported in 1969. Kaposi's sarcoma now accounts for 5% of all tumors associated with transplanted patients and alteration of the immunosuppression may have played a key role in these recipients. The most common site of Kaposi's sarcoma in transplanted patients are extremities but rare in head and neck area. We report a case of Kaposi's sarcoma on the hard palate in the kidney transplantation patient.

Intraaortic balloon counterpulsation (IAB) has been shown to prolong survival in the critically ill cardiac patients. Originally developed for use in the patients with cardiogenic shock, the indications have been expanded. But despite technical advances, the complication rate associated with IAB remains high. The most commonly reported complications include damage to the femoral artery and distal embolization. Other reported major complications are balloon rupture, limb loss, bleeding, systemic infection and bowel infarction. We report a patient complicated by ischemic colitis causing stenosis and intestinal obstruction after IAB insertion.
