The use of recombinant DNA technology to produce human growth hormone has resulted in a marked increase in availability of Growth Hormone(GH) to treat short stature due to GH deficiency and other conditions, such as Turner syndrome, familial short stature, chronic renal insufficiency and intrauterine growth retardation (IUGR). But, the GH therapy may result in the adverse events such as sodium and water retention, pseudotumor cerebri, slipped capital femoral epiphysis, growth of nevi, recurrence of tumor. We experienced a case of severe hypertension associated with GH therapy in a 14-year-old male who presented high blood pressure up to 190/100 mmHg and normalized at 2-3 weeks after discontinuation of GH. Therefore, we think that the blood pressure should be carefully monitored during GH therapy.

The thirteen DRB1, 6 DQA1, and 5 DQB1 alleles were defined in 362 healthy Korean controls using reverse dot blot hybridization method. The twenty-four immobilized SSOs for DRB1, 8 for DQA1, and 6 for DQB1 were used for this study. The frequencies of genotypes were DRB104 (17.1'Yo), '09 (13.1%), and '13 (11.6%); DQA1'01 (46.7%), 03 (30.8%), and '05 (11.7%); DQB1*03 (39.5%), '06 '(29.8%), and 05 (16.0%). ...continue...

The Korean hemorrhagic fever (KHF) is an acute febrile disease with characteristic of fever, bleeding tendency, and renal failure. There are many complications of Korean hemorrhagic fever such as infection, anemia, internal bleeding, hypopituitarism, respiratory, and neurologic complication. A few cases were reported on acute pancreatitis with hemorrhagic fever abroad, but there was no case about Korean hemorrhagic fever with acute pancreatitis in this country. We experienced a case of Korean hemorrhagic fever associated with suspected acute pancreatits. With review of articles, we report a case of 51 year-old woman with KHF, where acute pancreatitis developed during management.

BACKGROUND: Surveillance of surgical site infection is a main component of nosocomial infection surveillance. To perform a valid comparison of rates among hospitals, among surgeons, across time, surgical site infection rates must account for the variation in patient's underlying severity of illness and other important risk factors. So, a risk index was developed to predict a surgical patient's risk of acquiring a surgical site infection. The risk index score, ranging from 0 to 3, was the number of risk factors present among the following: (1) a patient with an American Society of Anesthesiologists preoperative assessment score of 3,4,5, (2) an operation classified as contaminated or dirty-infected, and (3) an operation lasting over T hours, where T depends upon the operative procedure being performed. METHOD: We performed surgical site infection surveillance according to patient risk index after cardiovascular surgery from Mar 1, 1997 to May 31, 1997. In addition, we also monitored nosocomial infection of all patients after cardiovascular surgery Data was collected prospectively, Surgical site infection rate was classified according to patient risk index and compared with NNIS (National Nosocomial Infections Surveillance) semiannual report of 1995. RESULT: Overall nosocomial infection rate was 18.9% and among all patients detected by surveillance protocols, pneumonia was the most common (6.3%) nosocomial infection after cardiovascular surgery, and the remaining infections were distributed as follows: surgical site infection 45%, urinary tract infection 3.2%, bloodstream infection 3.2%. Surgical site infection rate for patient with scores of 0, 1, 2 and 3 were 0%, 3.1%, 4.6%, 66,7%, respectively and increased according to patient risk index (P<0.05). There is no statistical difference between our surgical site infection rate and 1995 NNIS semiannual report of surgical site infection rates (P>0.05). CONCLUSION: The patient risk index is a better predictor d surgical site infection risk than the traditional wound classification system and surgical site infection surveillance with patient risk index is useful for nosocomial infection surveillance after surgery.

Objectives: The purpose of this study was to assess the source and quality of information regarding cervical disc herniation available to patients on websites.Summary of Literature Review: Studies have shown that 92% of the Korean population regularly accesses and searches for medical information on websites. While a large amount of information exists on websites, there is a possibility that patients will be misled due to inaccurate information because there are no established criteria for qualitative evaluation. In addition, little research has been conducted on websites that provide information about cervical disc herniation. Materials and Methods: The search term ‘‘cervical disc herniation’’ was entered into the three most popular search engines in Korea (Naver, Daum, and Google). The first 50 websites displayed by each engine were selected for inclusion in this study and were categorized as academic, commercial, physician, non-physician, government organization, and unspecified. Information was assessed in terms of DISCERN, accuracy, and exhaustivity scores, and a total summary score was calculated for each website. Results: Among the theoretical total of 150 websites, 83 unique and relevant websites were identified. The distribution by source was as follows: non-physician, 34.9%; physician, 27.7%; commercial, 13.3%; unspecified, 10.8%; academic, 9.6%; and government, 3.6%. Academic and government websites obtained the highest total summary scores, with statistical significance when compared to other types (p=0.03). Conclusions Website information on cervical disc herniation is generally limited. Institutional improvement efforts are needed to foster an environment where patients can receive high-quality medical information, and physician groups should play a central role in this process.

PURPOSE: The purpose of our study was to review the perinatal clinical characteristics of extremely low birth weight(ELBW) infants and determine their risk factors of their deaths. METHODS: The medical records of 96 infants weighing less than 1,000g, who were born at Seoul National University Hospital and admitted to our neonatal intensive care unit(NICU) were analyzed retrospectively on the basis of clinical characteristics, obstetrical problems, postnatal complications and outcome. RESULTS: The annual birth rate of ELBW infants was 0.11% to 0.90% of total live births and the mean annual birth rate was 0.56% at Seoul National University Hospital. Preeclampsia was the most common obstetrical problem(34.4%), followed by incompetent internal os of cervix(IIOC) (13.5%), multiple pregnancy(13.5%) and in vitro fertilization(IVF)(13.5%). Respiratory distress syndrome(RDS) was the most common postnatal complication(78.1%), followed by sepsis(60.4%) and apnea(39.6%). Comparing the ELBW infants weighing less than 750g with those weighing more than 751g, sepsis was more frequent in the latter group(p<0.05), whereas high grade intraventricular hemorrhage(grade Ill) was more frequent in the former group(p<0.05). Otherwise there was no statistically significant difference concerning the frequency of perinatal complications between two groups. Comparing the ELBW infants born before the year 1991, when surfactant treatment started to be used routinely at our NICU, with those born after the year 1991, apnea and sepsis could be observed more frequent in the latter group(p<0.05). Otherwise there was no statistically significant difference in the frequency of perinatal complications between two groups, The survival rate of ELBW infants was 0.0% in 1986, 50.0% in 1991 and 40.0% in 1995. The risk factors of neonatal deaths of ELBW infants included birth weight, gestational period, mode of delivery, IIOC, RDS, apnea, pneumonia, pneumothorax, acute renal failure(ARF) and infections(except pneumonia), but analyzing these risk factors by multivariate logistic regression analysis, the resultant significant independent risk factors consisted only of birth weight, RDS and pneumonia(p<0.05). There was no statistically significant difference in survival rate between ELBW infants born before and after the year 1991, but there was a tendency toward increasing survival rates in the latter group. CONCLUSION: Recently, the survival rate of ELBW infants is improving steadily, but is still lower than that of western countries and postnatal morbidity remains high. Therefore, there is an urgent need to give more efforts to the neonatal intensive care of ELBW inFants in order to increase survival rates and reduce postnatal morbidity. But it is more important to reduce preterm birth by the treatment of preventable obstetrical risk factors.
