OBJECTIVE: To evaluate the results of second-trimester maternal serum triple-marker screening test for Down syndrome and open neural tube defects in singleton pregnancies conceived from in vitro fertilization, the screen positive rates and triple-marker level of patients conceiving singleton pregnancies by IVF were compared to those of pregnancies conceived naturally. METHODS: Two hundred singleton pregnancies conceived by IVF and naturally conceived pregnancies who had done maternal serum screening test during the second trimester were analyzed from January 1995 to April 1998. RESULTS: One (0.5%) of the 200 cases of IVF singleton pregnancies had a positive result for Down syndrome compared with 1% of screen positive rate in the 200 cases of naturally conceived pregnancies. The median level of the triple markers were 0.92 multiples of the median(MoM) for alpha-fetoprotein(AFP), 1.44 MoM for unconjugated estriol(E3) and 0.87 MoM for human chorionic gonadotropin(hCG) respectively. CONCLUSION: The positive rate of triple test for Down syndrome and open neural tube defect in the two groups were significantly not different. As additional data are collected, corrected standards should be determined.

BACKGROUND: Total intravenous anesthesia with propofol can cause respiratory depression and apnea especially during induction of anesthesia. To study the possibility of reversal of respiratory depression during anesthesia with propofol, pretreated with nabuphine or not, the respiratory effects of doxapram to spontaneously ventilating patients were investigated. METHODS: Patients were divided into 4 groups - saline-propofol-saline group (SPS), saline-propofol- doxapram group (SPD), nalbuphine-propofol-saline group (NPS), and nalbuphine-propofol-doxapram group (NPD). After saline or nalbuphine pretreatment, anesthesia was induced with propofol and then doxapram or saline was intravenously injected. Apneic time interval, blood pressure, heart rate, respiratory rate, minute ventilation, end tidal CO2 partial pressure and oxygen saturation were measured in every minutes during induction of anesthesia. Percent changes of each values were compared. RESULTS: There is no differences in apneic time intervals in each groups. The percent change of first minute ventilation in SPD group after doxapram injection unchanged significantly compared with those depressions of SPS, NPS and NPD group (p<0.05). Respiratory rates increased in SPD and SPS groups after laryngeal mask insertion. There is no differences in minute ventilation, respiratory rate and end-tidal CO2 concentration between nalbuphine pretreated groups regardless of doxapram injection. CONCLUSIONS: Doxapram has effect in increasing minute ventilation after propofol induction within first few minutes, but it cannot reverse respiratory depression during propofol induction pretreated with nalbuphine.

The cases of 82 humeral shaft fractures were evaluated at the Department of Orthopedic Surgery, Chosun University Hospital, during the ten years period from January 1978 to December 1987 and the following results were obtained. 1. The most common type was transverse fracture (59.8%) and the most common site was middle one third (61.0%). 2. The average time of bone union were about 9.6 weeks in non-operative cases and 9 weeks in operative cases. 3. The radial nerve palsy was more common in transverse fracture of humerus at the middle one third level. 4. Among the 28 radial nerve palsy associated with humerus fracture, 19 cases were treated by conservatively, and 9 cases were treated by surigical exploration. 73.7% of conservatively treated cases and 77.0% of operatively treated cases regained most of the functional lost of the radial nerve.

In Korea, all domestic made test systems for detecting antibodies in HIV-1 contain the antigens from human immunodeficiency type 1 (HIV-1) subtype B. However, because HIV-1 subtype O is significantly different in amino acid sequences from all other subtypes of HIV-1, there has been a need for developing a test for detecting antibodies in subtype O. For this purpose, the entire nucleotide sequence corresponding to the extracellular domain of the transmembrane glycoprotein of HIV-1 subtype O was synthesized with consideration of Escherichia coli cordon usage. Various regions of the extracellular domain were cloned into E. coli expression vectors and tested for levels of protein production. The nucleotide sequence, named ECTM, that can encode a 129 amino acid-long peptide, was found to be expressed at a high level in E. coli. The protein of approximately 17 kDa specifically reacted with sera from individuals infected with HIV-1 subtype O. The ECTM protein was purified to near homogeneity by the CM-T gel chromatography, using concentrated, denatured inclusion bodies. In Western blot analysis, the purified viral antigen reacted with sera from individuals infected with subtype O more efficiently than subtype B. The enzyme linked immunoabsorbent assay (ELISA) system was developed using the subtype O viral protein and compared with the commercially available kit lacking the antigens from subtype O. The ELISA kit containing the subtype O antigen ECTM alone efficiently reacted with sera from individuals infected with subtype O. The subtype O antigen-containing kit produced a positive absorbence even when sera were diluted 512-fold, suggesting a high sensitivity. The commercially available kit also reacted with subtype O sera, but produced a negative result at a dilution of 8-fold. Our results suggest that the currently available kit may not be able to efficiently detect subtype O sera and that the viral protein developed in this study may be added to the current system to maximize the detection of sera from individuals infected with subtype O.

Chusid et al proposed diagnostic criteria of hypereosinophilic syndrome (HES) that remain valid today. These were, (1) a sustained peripheral blood eosinophil count of more than 1500/L present for longer than 6 months ; (2) no evidence of other apparent causes for eosinophilia, and (3) presumptive signs of parenchymal organ involvement. Any organ system may be affected in HES, but the most severe clinicopathological involvements are of the heart and nervous system. Although multiple organ systems may be involved, the most common cause of morbidity and mortality is cardiac involvement with extensive fibrous thickening of the endomyocardium and overlying thrombus. We report a case of acute peri-myocarditis with eosinophilia, which was confirmed as eosinophilic myocarditis by endomyocardial biopsy, with literature review.
