We reported a case of subchorionic placental cyst with maternal floor infarction in 32-year-old multigravida. In this case the infant without growth retardation was delivered at fuU term by repeat cesarean section. A 5.8*5cm placental cyst detected prenatally by ultrasound was shown subsequentty to be a subchorionic cyst without thrombohematoma. The cyst was unilocular and attached near the cord insertion, and it contained straw-colored fluid. There was no other placental abnormalities except placental inFarction on matemal floor with fibrin deposition. It is necessary to differentiate placental cystic lesions by ultrasonographic and pathologic examination because placental abnormalities could be associated with perinatal complications.

PURPOSE: Mycoplasma pneumoniae pneumonia (MP) is associated with the exacerbation, timing, and onset of asthma. The goal of this study was to elucidate the impact of MP on eosinophil-related hyper-reactive amplification in atopic children. METHODS: We studied 48 patients with MP (26 atopic, 22 non-atopic), between 3 and 12 years of age. Serial changes in blood eosinophil counts, serum interleukin-5 (IL-5), and serum eosinophil cationic protein (ECP) levels were measured in atopic and non-atopic children with MP upon admission, recovery, and at 2 months post-recovery. Serum IL-5 and ECP levels were measured by enzyme-linked immunosorbent assays; eosinophil counts were measured using an autoanalyzer. RESULTS: Serial changes in serum IL-5, ECP, and total eosinophil counts were significantly higher in atopic patients, relative to non-atopic controls (P< or =0.001). Serum IL-5 and ECP levels were significantly higher in atopic patients at all three time points tested, while eosinophil counts were higher in the clinical recovery and follow-up phases, but not in the acute phase. Furthermore, among atopic patients, serum ECP levels were significantly higher in the recovery and follow-up phases than in the acute phase. CONCLUSIONS: The present study demonstrated significant differences in eosinophil counts, serum IL-5, and serum ECP levels between atopic and non-atopic children with MP at admission, recovery, and 2 months after clinical recovery. These outcomes are suggestive of eosinophil-related hyperreactivity in atopic children, with this status maintained for at least 2 months after MP.

The CYP11A1 gene encodes for the cholesterol side-chain cleavage enzyme (P450scc), which initiates steroid hormone biosynthesis. Defective P450scc activity results in severe glucocorticoid and mineralocorticoid deficiencies. We describe a case of P450scc deficiency due to a novel homozygous CYP11A1 variant inherited from the mother with a possibility of uniparental disomy (UPD). The patient was a female, had no family history of endocrine disease, and showed adrenal insufficiency at 13 days of age. Hormonal analysis with an adrenocorticotropic hormone stimulation test showed both glucocorticoid and mineralocorticoid deficiencies, presumed to be a defect of the early stage of steroidogenesis. Exome sequencing reported a novel homozygous frameshift variant of CYP11A1 (c.284_285del, p.Asn95Serfs*10), which was inherited from the mother.Additionally, homozygosity in 15q22.31q26.2, which included CYP11A1, was identified using a chromosomal microarray. It was suggested that the possibility of maternal UPD was involved as the cause of a P450scc deficiency by unmasking the maternally derived affected allele. To our understanding, P450scc deficiency associated with UPD encompassing CYP11A1 had not been reported in Korea before. Genetic analysis can help diagnose rare causes of primary adrenal insufficiency, including P450scc deficiency.

PURPOSE: To assess the risk factors for endothelial cell loss after phacoemulsification with implantation of intraocular lens according to anterior chamber depth (ACD). METHODS: This prospective study included 94 eyes of 94 patients undergoing phacoemulsification cataract surgery. To assess the risk factors for corneal endothelial cell loss, we examined seven variables at 1 day, 1 week, 6 weeks, and 12 weeks postoperatively in each ACD-stratified group. RESULTS: Multiple linear regression analysis showed that the only variable influencing the percentage decrease in corneal endothelial cell density throughout the postoperative follow-up period in the long ACD group (ACD III) was nucleosclerosis. The variables influencing the percentage decrease in corneal endothelial cell density in the short ACD group (ACD I) at one day and one week postoperatively were corneal incisional tunnel length and nucleosclerosis. CONCLUSIONS: Risk factors for endothelial cell loss after phaoemulsification were different according to ACD. Long corneal tunnel length can be one of the risk factors for endothelial cell loss in short ACD eyes.

Parry-Romberg syndrome(Progressive hemifacial atrophy), described in the last century by Parry(1825) and Romberg(1846), is a very rare disorder characterized by a slowly progressive and self-limited unilateral(rarely bilateral) atrophy of the faces affecting variably the skin, subcutaneous fat tissues, musculature, connective tissue, cartilage and bones. And this disorder is usually accompanied by contralateral Jacksonian epilepsy, trigerminal neuralgia, and changes in the eyes and hair. The onset is slow and progressive, starting at 5-15 years of age and lasting from 2-10 years, ending with the face being "burned out". There are a few cases of this disease which presented during the neonatal period. This disorder seems to affect females more than males, and its etiology and incidence has yet to be determined. Trauma, infection with a slow virus, sympathetic dysfunction, immunological abnormality and cranial vascular malformation are proposed causes. No typical or consistent neuropathologic findings occur. No specific treatment for the syndrome exists; however, various reconstructive surgical procedures can have in reasonably good cosmetic effects, as well as antiinflammatory or immunosuppressive treatment. We report a case of Parry-Romberg syndrome, which was presented at 1 month of age, and has progressd to contralateral hemiparesis.

INTRODUCTION: Hydroxyapatite(HA) coating implant can accelerate osseointegration, however, there are many controversies. MATERIALS AND METHODS: This study examined the early osseointegration of two types of hydroxyapatite coated implants. Twelve adult male miniature pigs (Medi Kinetics Micropigs, Medi Kinetics Co., Ltd., Busan, Korea) were used in this study. In the implants placed in the mandible, a histomorphometric evaluation was performed to evaluate the bone-implant contact (BIC) ratio. RESULTS: The BIC ratio increased with time. TS III HA and Zimmer HA were not significantly different (P>0.05). At 8 weeks, the BIC of Zimmer HA was higher than TS III HA, but there was no significant difference (P>0.05). CONCLUSION: HA coated implants will accelerate early osseointegration.

Actinomycoces is a gram positive, anaerobic, branching and non-acid fast bacterium which is a normal habitant of the skin, oral cavity, tonsil and gastrointestinal tract and its human infection is rare. Pelvic actinomycoses is frequently caused by Actinomycoces israel-ii. It is chronic, progressive, and more suppurative than granulomatous disease, and the symptoms are usually persistent and gradual, therefore the misdiagnosis and improper trea-tment are not uncommon. Actinomycoses is generally classified as cervicofacial, abdominal and thoracic type ac- cording to the site of the primary infection. Many actinomycotic pelvic infections in women used intrauterine device with long du- ration were reported, in contrast, others suggest that actinomycoces developed opportunistic infection irrespective of intrauterine device presence. We have experienced 4 cases of pelvic actinomycoses, one case with IUD(Lippes' loop) in a 47 year old woman, the other case with abdominal wall ctinomycoses in a 34 year old woman, the third case without IUD in a 41 year old woman, the fourth case with IUD(Cu-7) in a 37 year old woman and reported them with a review of literature.

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.
