  • This paper considers Group Testing as one of combinatorial problems. The group testing first began to inspect soldier's syphilis infection during World War II and have long established an academic basis. Recently, there has been much interest in related areas because of the rediscovery of the value of the group testing. The group testing is the same as finding a few defect samples out of a large number of samples, which is similar to the inverse problem of Compressed Sensing. In this paper, we introduce the definition of the group testing, and specify the classes of the group testing and the bounds on performance of the group testing. In addition, we show a lower bound for the number of tests required to find defective samples using the theoretical theorem which is mainly used for relationship between conditional entropy and the probability of error in the information theory. We see how our result can be different from other related results.

  • Purpose:This study compares the maternal characteristics and birth outcomes of infants of Asian immigrant mothers from developing countries with those of the infants of Korean mothers. Methods:In this multicenter and retrospective study, Asian immigrant women who had delivered between January 2005 and June 2008 were enrolled from9 Medical Centers. In all, 333 births to Asian immigrant women from developing countries (Asian-Korean infants) were included in this study. In addition, sex-, birth year-, and gestational age-matched 333 neonates born to Korean mothers were selected as the control group (Korean infants). On the basis of the hospital data, we investigated the nationality, age, and medical history of the mothers and compared the incidence of congenital infection, Apgar score, weight, height, and head circumference of Asian-Korean infants with those of the Korean infants. Results:The average maternal age of Asian women from developing countries at birth term was 26.7 years, which was significantly lower than that of Korean women (30.8 years, P<0.05). The birth weight of Asian-Korean infants (2,869 g) was significantly smaller than that of Korean infants (2,995 g, P<0.05). There was a significant difference in the incidence of congenital syphilis infection between the Asian-Korean infants and Korean infants (5 cases vs. 0 case, P<0.05). Conclusion:There were significant differences in the perinatal outcomes between the Korean and Asian-Korean infants. A multicenter large-scaled study should be performed to analyze the perinatal outcomes of Asian-Korean infants.

  • Background: Endovascular stent-graft insertion in aortic diseases is now generally accepted as an attractive alternative treatment modality. We reviewed our clinical experiences of endovascular stent-graft insertion in thoracic aorta. Material and Method: Since 1995, we performed 8 cases of endovasclar stent-graft insertion. Preoperative diagnoses were aortic aneurysms in 4, traumatic aortic ruptures in 3, and ruptured aortic pseudoaneurysm in 1. All procedures were performed in angiography room with the guidance of fluoroscopy. The stent-graft device is a custom-made 0.35mm thickness Z-shaped stainless steel wires, intertwined with each other using polypropylene suture ligation. It is covered with expanded Dacron vascular graft. Result: All procedures were performed successfully. Follow-up studies revealed 2 minimal perigraft leakages. There was no significant leakage or graft migration. 2 patients expired due to multiple organ failure and fungal sepsis. Other survivors(6) are doing well. Conclusion: Endovascular stent-graft insertion is relatively saft and effective treatment modality in the managment of various types of aortic diseases. In may be an effective alternative in aortic diseases of great surgical risk.

  • Currently, sexually transmitted diseases (STD) are referred to as "sexually transmitted infections" (STIs) in the sense of including asymptomatic infections. STIs have a range of interrelationships. This study used the STI defined by the Minister of Health and Welfare of the Republic of Korea, and targeted syphilis, gonorrhea, chlamydia infection, chancroid, genital herpes simplex, condyloma, human papillomavirus, and non-gonococcal urethritis. The factors were characterized by identifying multiple and simultaneous STIs. This study used the data from the laboratory information system of a consigned inspection institution located in Seoul from 2014 to 2019. In this study, multiple STIs were identified as overlapping STIs of a double infectious source (10 types) and multiple STIs of a third infectious source (6 types). Among the 16 types of multiple STIs, U. urealyticum (9 types), HSV-2 (8 types), C. trachomatis (7 types), HPV 6, 11 (7 types), N. gonorrhoeae (6 types), and T. pallidum (1 type) were included. Therefore, additional research on interrelationship studies, such as STIs, which has the highest proportion of multiple STIs, will be necessary.

  • For the effective control of Syphilis, many investigators have developed a more rapid, simple and economical screening serological test which is adequately sensitive and specific. To fulfill the requirements of a more rapid serologic test for syphlis, a substitute for the conventional serum specimen was needed since considerable time and labor are involved in the processing of blood to serum. Burdon suggested the use of plasma in the serologic tests for syphilis as a substitute for serum. He noticed that plasma was more sensitive than serum in the Kline and Kahn tests, and attributed this to the presence of more antibody-like substance, "reagin" in plasma than in serum. However, to make plasma sufficiently sensitive, it was necessary to inactivate plasma by heating at a temperature of $56^{\circ}C$ for about 30 minutes. Heating of plasma resulted in the precipitation of fibrinogen which made centrifugation necessary to obtain dear plasma. Since the chief disadvantage to the use of unheated plasma(or serum) was a reduction in sensitivity of results-which probably was due to a labile factor such as complement-Portnoy et al began to consider rapid chemical methods of inactivation of plasma(or serum). They experienced that choline chloirde was shown to be anticomplementary which suggested its use as an inactivating agent for unheated plasma(or serum). In 1959 Portnoy et al reported the Rapid Plasma Reagin(RPR) Test for syphilis which is a more rapid, economical and simple. But still this test has many disadvantages as a rapid performing, field and office procedure, because it requires the usual laboratory equipments such as centrifuge, rotating machine, microscope etc. To substitute these disadvantages of the RPR test, in 1962, Portnoy et al developed the Rapid Plasma Reagin(RPR) card test for syphilis, which has the following advantages: a) Simplicity and rapidity of performance, b) Requires no laboratory equipments, c) Stable antigen suspension, d) Adequate sensitivity and specificity. This RPR card test can be used as a rapidly performing and screening test in field investigation, outpatient clinics, small laboratories and hospitals doing limited syphilis serology, and predonor in blood bank. Private clinic which has limited laboratory equipment and technic for syphilis serology can also use this RPR card test as a tool in the rapid diagnosis of syphilis. It was thought that this RPR card test is a useful tool in Korea for private physician and mass survey for syphilis diagnosis. But Portnoy patented the reagents needed for the performing the RPR card test. Therefore authors developed newly the reagents and according to Portnoy's method evaluated the newly developed. RPR card test compared with the VDRL, Kolmer CF, and RPCF tests. The RPR card and VDRL tests were performed plasma and serum from the total 1,132 cases. Among these 1,131 cases, 521 were syphilis suspected laboratory specimens, and 611 were syphilis unsuspected healthy young men. After screening with these two tests, the RPR card and VDRL tests, reactive specimens to the above one or both tests were retested by the Kolmer CF and RPCF tests.

  • Osteomyelitis means inflammation of the bone marrow. It usually begins in the medullary cavity, involving the cancellous bone; then it extends and spreads to the cortical bone and eventually to the periosteum. The cause is usually thought to be microbiological. But there still are factors that predispose to produce a possible bone infection such as injuries, syphilis, actionomycosis, chronic kidney failure, alcoholism, malnutrition, radiotherapy, and chemotherapy. Treatment of modalities have been directed toward eradicating microbes and improving circulation in the early stage. In the case presented, surgical debridement and IV antibiotics were the treatment of choice. Osteomyelitis in children is mainly affected in the mandible. And in childhood, the mandibular condyle is regarded as an important center of mandibular growth. Therefore, in young patients, osteomyelitis involving this region may cause a restraint of mandibular development, resulting in facial asymmetry. So diagnosis in the early stage is important in child with osteomyelitis. Recently, we have encountered an interesting case of osteomyelitis of the mandibular condyle in 9-year-old boy. So we present the case and review the literature about osteomyelitis.

  • This study was conducted to compare the delivery management including laboratory tests, medication and surgical procedures for the delivery in various medical facilities. Two university hospitals, two general hospitals, three hospitals, two private obstetric clinics, and two midwifery clinics in a large city were selected as they permitted the investigators to abstract the required data from the medical and accounting records. The total number of deliveries occurred at these 11 facilities between 15 January and 15 February, 1989 was 789 among which 606(76.8%) were vaginal deliveries and 183 (23.3%) were C-sections. For the normal vaginal deliveries, CBC, Hb/Hct level, blood typing, VDRL, hepatitis B antigen and antibody, and urinalysis were routinely done except the private clinics and midwifery clinics which did not test for hepatitis B and Hb/Hct level at all. In one university hospital ultrasonography was performed in 71.4% of the mothers and in one general hospital liver function test was done in 76.7% of the mothers. For the C-section, chest X-ray, bleeding/clotting time and liver function test were routinely done in addition to the routine tests for the normal vaginal deliveries. Episiotomy was performed in 97.2% of the vaginal deliveries. The type and duration of fluid infused and antibiotics administered showed a wide variation among the medical facilities. In one university hospital antibiotics was not administered after C-section at all while in the general hospitals and hospitals one or two antibiotics were administered for one week on the average. In one private clinic one pint of whole blood was transfused routinely. A wide variation was observed among the medical facilities in the use of vitamin, hemostatics, oxytocics, antipyreptics, analgesics, anti-inflammatory agents. sedatives. digestives. stool softeners. antihistamines. and diuretics. Mean hospital day for the normal vaginal deliveries of primipara was 2.6 days with little variation except one hospital with 3.5 days. Mean hospital day for the C-section of primipara was 7.5 days and that of multipara was 7.6 days and it ranged between 6.5 days and 9.4 days. Average hospital fee for a normal vaginal delivery without the medical insurance coverage was 182,100 Won for the primipara and 167,300 Won for the multipara. In case of the primipara covered by the medical insurance a mother paid 82,400 Won and a multiparous mother paid 75,600 Won. Average hospital fee for a C-section without the medical insurance was 946,500 Won for the primipara and 753,800 Won for the multipara. In case of the primipara covered by the medical insurance a mother paid 256,200 Won and a multiparous mother paid 253,700 Won. Average hospital fee for a normal vaginal delivery in the university hospitals showed a remarkable difference, 268,000 Won vs 350,000 Won, as well as for the C-section. A wide variation in the laboratory tests performed for a normal vaginal delivery and a C-section as well as in the medication and hospital days brought about a big difference in the hospital fee and some hospitals were practicing the case payment system. Thus, standardization of the medical care to a certain level is warranted for the provision of adequate medical care for delivery.
