Chorioangioma is the most common primary tumor of the placenta. It is widely accepted to be formed from hamartomatous proliferation of angioblastic cells in early placenta. According to groups who systematically examined the placentas with the greatest scrutiny, the incidence of chorioangioma is 1~1.2% of all placentas examined. The clinical implication of chorioangioma has been emphasized due to its high association with hydramnios, antepartum and postpartum hemorrhage, premature onset of labor, or intrauterine fetal distress or death. The authors experienced a case of a 38-year old multigravida who had undergone 4 consecutive spontaneous abortions. The fifth pregnancy was carried to 35 weeks whereupon a dead fetus was delivered. The placenta was enlarged(950 gm) with multiple protruding nodules into the fetal surface. Microscopically, the nodule was composed of many vilous structures lined by chorionic epithelium. Within these structures was proliferation of endothelial lined capillaries some of which demonstrated ectatic change.

Melorheostosis is a rare entity while causes pain and stiffness in a limb and has an unknown etiology. It is characterized by roentgenographic appearance of melting wax dripping down one side of a candle along the major axis of long bone. The present case represents a melorheostosis of the left tibia accompanied by synovial chondromatosis in the left knee. Good result was obtained by arthrotomy of the left knee and removal of the bony masses in the joint.

BACKGROUND AND OBJECTIVES: Primary intervention by stent implantation during acute myocardial infarction is a novel strategy to provide better myocardial perfusion compared to thrombolysis or baloon angioplasty. We aimed to assess the reperfusion achieved by primary stenting, employing TIMI frame count for more objective and quantitative measurement. MATERIALS AND METHOD: Measurements for number of frames required to opacify standardized angiographic landmark branch(TIMI frame count) were determined for the coronary arteries of 77 normal controls and 65 patients with acute myocardial infarction who underwent primary stenting within 12 hours of symptom onset. RESULTS: In normal subjects, TIMI frame count for left anterior descending artery(LAD) was 1.3 times of mean count of right coronary artery(RCA) and left circumflex artery(LCx), and significant less than that of TIMI study(22.3+/-4.9 vs 36.2+/-2.6, p<0.05). TIMI frame count for RCA and LCx was similar to results of TIMI study. In infarct related arteries(IRA), corrected TIMI frame count(CTFC) after primary stenting was similar to those of normal control. Frame counts of RCA was larger compared to that of normal control, but statistically insignificant(23.0+/-7.5 vs 17.6+/-3.5, p>0.05). There was no difference of CTFC of non-infarct related arteries between patients and normal controls. CONCLUSION: The TIMI frame count of LAD artery in normal Korean subjects was significantly less than that of American counterpart. In patients with acute myocardial infarction, primary stenting appeared to provide improved coronary flow similar to that observed in normal subjects, as measured by TIMI frame counting.

Disseminated superficial actinic porokeratosis (DSAP) is one of the recently found skin disorderes, which was differentiated from classicaI porokeratosis (Mibelli) and senile keratosis etc. in view of clinical features and hietogenesis by Marvin E. Chernosky on 1967. The one was 60 years old female patient, who had been suffered from multiple dark-brownish keratotic uniform minute papules on dorsa of the hands, forearms and neck with accompanying itching sensation since about 20 year's old of her age. The another one was 38years old housewffe, wha had been suffered from same lesions of the former on the face, neck, extremities especially sun-light exposed area. In both cases, skin lesions were exacerbated during each summer season and increase in numbers of the skin lesions with more severe itching sensation. Chernosky postulated none of a dark-sklnned race affording natural protection against sun-light had skin lesion of D S A P, we were abIe to find out two cases of typical D S A P ih the Korea.

BACKGROUND: The present study aims to compare the pulmonary function of residents of Seoul special city (Seoul) and Jeju special self-governing province including Jeju city and Seogwipo city (Jeju), characterized by vastly different annual average airborne particulate matter with an aerodynamic diameter less ≤10 μm (PM10) concentrations, with the annual average PM10 concentration in Seoul being significantly higher than that in Jeju. METHODS: This cross-sectional study analyzed the pulmonary function test results and sociodemographic data of Korean adults ≥19 years of age derived from the 4th KNHANES, 2007–2009. A total of 830 individuals residing in Seoul or Jeju were included in this study. T-tests were used to analyze predicted values of forced expiratory volume in 1 sec (FEV1p), predicted values of forced vital capacity (FVCp) and FEV1/FVC ratio (FEV1/FVC), as dependent variables, to examine the differences in the subjects’ pulmonary function according to the city of residence. Stratified analysis was then performed to adjust for variables potentially affecting pulmonary function. The analysis was performed on subjects as a group and also following stratification according to sex and other variables. RESULTS: Seoul residents had a significantly lower FVCp than that of the Jeju residents (difference: 3.48%, p = 0.002). FEV1p, FVCp and FEV1/FVC of male Seoul residents were significantly lower than those of male Jeju residents (difference: 6.99, 5.11% and 0.03, respectively; p < 0.001, p = 0.001, p = 0.001). In male subjects, statistically significant results were obtained even after adjusting the influence of other variables through stratified analysis. CONCLUSION: The present analysis was based on cross-sectional data collected at one point in time. Therefore, unlike longitudinal studies, it does not establish a clear causal association between the variables. Nevertheless, this study found that pulmonary function among subjects residing in Seoul was significantly decreased compared to that of subjects residing in Jeju.

PURPOSE: Because the preoperative diagnosis of xanthogranulomatous pyelonephritis (XGP) is difficult due to its similarities to other renal diseases, the diagnosis is made postoperatively in most patients. The aim of this study was to improve preoperative diagnosis of this disease. MATERIALS AND METHODS: We reviewed clinical characteristics, laboratory and radiological findings, preoperative diagnoses, and operative methods of 6 patients with XGP who underwent operation from March 1991 to July 1998. Mean age was 49.8 years (range 28 to 80) and male to female ratio was 1 to 2. RESULTS: All 6 patients had flank pain and urinary tract infection. Among 6 patients, there were 3 patients (50%) with renal staghorn stone and 1 (16.7%) with ureteropelvic junction stricture. No patient was diagnosed as XGP preoperatively. Three patients (50%) diagnosed as pyonephrosis with staghorn stone preopratively underwent simple nephrectomy and 2 patients diagnosed as renal mass preoperatively underwent radical nephrectomy. One patient diagnosed as renal abscess extended to retroperitoneum and psoas muscle preoperatively was diagnosed as XGP through intraoperative frozen section biopsy of renal tissue and underwent partial nephrectomy and drainage. CONCLUSIONS: Preoperative diagnosis of XGP will be raised through better understanding of the clinical characteristics and radiologic findings of this disease.
