The pathogenetic mechanism of focal segmental glomerulosclerosis (FSGS) is not known. Some authors suggest glomerular hypertrophy may precede the development of FSGS in patients with minimal lesion. It was recently reported that the size of nonsclerotic glomeruli in adults with FSGS is significantly larger than that of cases with minimal lesion. It is not clear whether glomerular hypertrophy observed in adults with FSGS is also seen in children with FSGS. Thus, we have analyzed 37 renal biopsies from children with FSGS by morphometry and the data were compared with 37 renal biopsies from age- and sex-matched patients with minimal lesion. The number of glomeruli submitted for morphometric analysis was 22.6+/-14.2 in cases with FSGS and 30.9+/-11.4 in cases with minimal lesion. Mean glomerular volume (MGV) in FSGS group was significantly larger than that of minimal lesion [(13.1+/-3.9) x10(5) microm3 vs. (10.1+/-1.9) x10(5) microm3, p<0.001]. The relative interstitial volume of renal cortex in patients with FSGS was significantly larger than that of minimal lesion [(0.106+/-0.051) microm3/microm3 vs. (0.029+/-0.012) microm3/microm3, p<0.0001]. In FSGS, the percentage of glomeruli with FSGS was significantly correlated with relative interstitial volume of renal cortex (r=0.79, p<0.0001). As is the case for adult FSGS, MGV of children with FSGS is significantly larger than that of minimal lesion. Thus, the presence of glomerular hypertrophy observed in biopsies with minimal lesion nephropathy seems to be an indication that the coexistent FSGS lesions are undetected due to sampling problems.

PURPOSE: This study was conducted to compare the rates of industrial accidents in workplaces that adopted the 2011 Workplace Health Promotion Subsidy Scheme before and after the implementation. METHODS: The study analyzed the raw data of industrial accidents of 304 workplaces which received subsidies for health promotion activities in 2011. The raw data covered the period from February 2010 to July 2012, based on the dates of industrial accidents. RESULTS: Workplaces subsidized for health promotion activities reported fewer occurrences in staff injuries and illnesses than before the subsidization, as the total number of industrial accident victims dropped from 0.35 to 0.24. The rate of industrial accidents also dropped from 0.49 to 0.35, with the number of working days decreased from 35,433 to 23.867, about 33%. CONCLUSION: The study showed that financial support for health-promoting activities contributed to the decease in industrial accidents, which is an important indication advocating the need for corporate and government investment on workers health promotion programs. Furthermore, this study is also significant as it is the first research conducted in Korea to examine the impact of a workers health promotion project using a direct indicator, the rate of industrial accidents.

This study was conducted to evaluate the association of job characteristics and stress indicators, from May 1st to 10th, 1996. The study population was 210 workers (clerical workers, 67; engineers, 82; assembly line workers, 61) engaged in a television manufacturing company. A questionnaire method was used to collect the data regarding to job demand, job control, behavioral type, life style and psychiatric symptoms. Clinical examination was conducted to measure blood pressure, serum cholesterol, fasting blood sugar and HbA1c. Percentage of high subjective job strain group was significantly higher in clerical workers(9.0 %) than in engineers(4.9 %) and in assembly line workers(3.3 %) (p < 0.01). Mean values of fasting blood sugar and HbA1c were significantly different between types of occupation and were the highest in clerical workers (p < 0.05). Significant association was found between perceived job characteristics and psychiatric symptom score (p < 0.01). The more job demand and the less job control was, the higher psychiatric symptom score was reported. Diastolic blood pressure was significantly related to job control (p < 0.05). The more job control was, the higher blood pressure was reported. In multiple regression analysis, job demand, job control and age were significant variables explaining the psychiatric symptoms and R2 was 0.23. Perceived job characteristics and type of occupation were not significant in explaining diastolic blood pressure and cholesterol. Type of occupation, job demand, age and BMI were significant variables explaining lasting blood sugar and R2 was 0.25. Type of occupation was the only significant variable explaining HbA1c and R2 was 0.07. According to this result, occupational type and subjective job characteristics must be considered in study of job stress. As a result of multiple analysis, subjective job characterics are significantly related to psychiatric symptoms and type of occupation is significantly related to fasting blood sugar and HbA1c.

Purpose: This study investigated the complications and patterns of implants that confronted with the extruded natural teeth. Materials and Methods: Among patients who received implant treatment between 2006 and 2018 at Chosun University Dental Hos-pital, only implants that had a maintenance period of at least 5 years and that both implants and confronting natural teeth could bemeasured and compared on a radiograph were selected. They were divided into two groups. Group 1, experimental group consisted of Implants confronting the extruded natural posterior teeth (n = 167: maxilla (Group 1max ) = 92, mandible (Group 1man ) = 75) and Group 2, control group consisted of Implants confronting the normal natural posterior teeth (n = 656: maxilla (Group 2max ) = 272, mandible (Group 2man ) = 384). Results: The incidence of complications between Group 1 and Group 2 was statistically significant. In particular, there was a statistically significant difference between the frequency of marginal bone loss and the amount of marginalbone loss. Conclusion The extruded natural tooth may cause more frequent complications including bone resorption in the oppos-ing implant.

PURPOSE: Intussusception is one of the most common cause of childhood intestinal obstructions. Early diagnosis is essential to avoid treatment delays, which can increase morbidity and mortality. METHODS: In order to evaluate the factors contributing to air-reduction failure, we reviewed cases of childhood intussusception admitted via the ER and managed by air enema reduction from 1994 to 1998. They were divided into two groups and compared retrospectively by using medical records. Group I was the operation group after air-reduction failure, and group II was the air-reduction group. RESULTS: In 319 cases (279 patients), group I consisted of 112 cases (110 patients), and group II consisted of 207 cases (169 patients). No differences in age, sex, body weight, location of intussusception, laboratory findings (leukocytosis and thrombocytosis), presence of bloody stool, and body temperature were noted between the two groups. Factors significantly contributing to air-reduction failure were duration of symptoms, type of intussusception and a few physical findings (abdominal distension, palpable mass, lethargy, and vomiting). The recurrence rate of group I was significantly lower than that of group II, and most recurrences developed in the first postoperative month. CONCLUSION: Childhood intussusceptions of a non-ileocolic type with longer durations of symptoms and severe clinical findings have a higher chance of air-reduction failure.

Holt-Oram Syndrome is an autosomal dominant disorder characterized by the association of upper-limb abnormalities and congenital heart disease. A woman with no family history of genetic disease underwent antenatal sonography at 27 weeks' menstrual age to screen for fetal anomalies. Ultrasonography revealed abnormalities in the upper limbs. The limb abnormalities included abscence of bilateral thumbs and radius: the left humus was short. Pregnancy termination was performed. The postnatal chromosomal analysis revealed a normal 46XX karyotype and the autopsy finding confirmed the Holt-Oram syndrome. We report a case of Holt-Oram Syndrome in fetus with unaffected parents with brief of the literatures.
