In order to establish the predicted normal values of the systolic time intervals the duration of the systolic time intervals measured from simultaneous recordings of the electrocardiogram, the phonocardiogram and the carotid pulse tracing. The subjects studied were 160 healthy males and 160 females. The mean ages of males and females were 29 and 31 years old, respectively. The transformation period was not closely related to heart rate, and its mean values for males and females were 58 and 56 msec., respectively, and the mean for males and females combined was 57 msec. The remainder of the systolic time intervals, however, showed a significant linear and inverse relation to heart rate. Thus, based upon these data regression equations for the prediction of the normal values of electromechanical systole, left ventricular ejection time, mechinical systole, precjection period andisovolumiccontraction time for males, females, and males and females combined were obtained.

BACKGROUND: Healthy cities of Korea have engaged in various activities regarding the Korea Healthy Cities Partnership, and research activities on healthy cities is one of the important area. In the present context, due to the current policy to pursue Sustainable Development Goals locally and globally, it is essential to emphasize the importance of healthy city. Therefore, it is important to identify the research trend related to healthy city. The aim of this study was to find out research trend of healthy city studies from 1990 to 2014 by reviewing published papers and studies systematically. Based on the finding of the study, the necessary implications on future research directions of the healthy city are obtained. METHODS: The area of this study is domestic journal (Korea), international journal, thesis, and research report focusing on healthy city from 1990 to 2014. The selection of data was performed using keyword is based on domestic and international database. The analysis criteria were divided into year of publication, type of study, subjects, study methods, and study area. RESULTS: One hundred twenty papers were selected for the analysis. Papers related to the healthy city issue were published 4.8 times in an average in a year during that the period. However, the number of papers published increased dramatically in the recent 4 years. Of total, 28 papers (44.4%) focused on the healthy city policy and urban environmental improvement, 18 papers (28.6%) focused on health promotion, and the remaining were program centered. Most papers (71 out of 120) used quantitative study methods. Of total studies, studies have conducted in Jinju city (9), Wonju city (8), Changwon city (6) and Gangnam-gu (5), respectively, as a study area of healthy city. CONCLUSION: First, domestic healthy city researches has been gradually increasing every year, over the past 10 years which has heightened interest in healthy cities. Second, the expansion of the various areas of research is required in order to contribute to future sustainable healthy city. Third, in recent years, by taking advantage of a variety of research methods, conducting the qualitative and mixed method research is considered to be a desirable change.

PURPOSE: The aim of this study was to assess health-related behavior of pregnant women and breastfeeding mothers by investigating relevant risk factors. METHODS: Data of 10,396 women (age 19 to 49 years) from the Korea National Health and Nutrition Examination Survey report from 2007 to 2012 was used to analyze factors associated with health-related behavior. The subjects were divided into pregnant women; breastfeeding mothers; and non-pregnant women. Bottle feeding mothers were excluded. RESULTS: Current smoking rate including self-reported smoker and/or positive cotinine urine test were lower for pregnant or breast-feeding group than non-pregnant group. Heavy-drinking was not different among groups while monthly drinking rate was higher in non-pregnant group. Rate of stress recognition was lower in pregnant and breast-feeding group than non-pregnant group. Rate of experience for depressive symptoms and rate of suicidal ideation were not different among groups. CONCLUSION: Pregnant women and breast-feeding mothers maintain a good pattern of health-related behavior compared to non-pregnant women. However, substantial proportion of pregnant women and breast-feeding mothers continue to drink and smoke. This shows the need for a plan that will modify health-related behavior.

BACKGROUND: Pericardiocentesis is not routinely recommended in most patients with pericardial effusion (PE), except for patients with cardiac tamponade. However, the long-term follow-up results in patients with clinically not significant PE are few. METHODS: Sixty-five consecutive patients (mean age:57 yrs, 26 males) out of 87 patients with PE, who were clinically not serious, were studied prospectively once in every two month for mean 6 months (2-12 months) without any specific treatment. The amount of PE was measured at the enddiastole period of parasternal long axis view and apical four chamber view. RESULTS: The incidence of insignificant PE in our echocardiographic laboratory is 3.4% (n=87 from 2461). The maximal accumulation site of PE was posterior (n=51, 79%). The next is anterior (n=11, 17%) and right ventricular side (3, 5%). The amount of PE is less (0.37+/-0.17cm vs 0.64+/-0.54cm, p=0.018) in localized PE (n=24, 37%) than that of diffuse form (n=41, 63%), which spreads to more than 2 chambers. The presumptive etiologies of PE were unknown (n=41), heart failure (n=5), myocardial infarction (n=6), viral (n=3), and others (n=10). The amount of PE was decreased from 0.54+/-0.46 cm to 0.30+/-0.26 cm, 0.23+/-0.24 cm, and 0.21+/-0.23 cm 2, 4, and 6 months after intial evaluation, respectively, without any complication.

PURPOSE: In developed countries, acute rheumatic fever appears to be a vanishing disease. In Korea, the incidence and severity of acute rheumatic fever (ARF) has significantly decreased in recent 30 years. According to this report, Korea sustained low incidence of ARF. METHODS: The medical records of 5 children diagnosed as ARF from January 2000 to September 2006 were reviewed retrospectively about clinical manifestations and laboratory findings. RESULTS: The average incidence of rheumatic fever was 0.17 per annual pediatric in-ward 1,000 patients. During study period, only 1 case had a definite history of preceding infection. Among 5 patients, the incidence of major manifestations were as follows:carditis 5 cases, chorea 1 case, arthritis 1 case and erythema marginatum 2 cases. Clinical findings of carditis were cardiac murmur, cardiomegly, congestive heart failure and pericardial effusion. Significant valvular lesions were mitral and aortic insufficiency. Minor manifestations and other clinical manifestations were fever, arthralgia, dyspnea, coughing, palpitation, weakness and chest pain. Laboratory findings were increased antistreptolysin O titer, positive C reactive protein (CRP) and increased erythrocyte sedimentation rate (ESR). CONCLUSION: The incidence of ARF has reduced but rheumatic carditis varies in severity from moderate to severe cardiac involvement. For many reasons ARF is being diagnosed inappropriately resulting from lack of awareness about the disease due to rarity and secondary prophylaxis. We should be aware of acute rheumatic fever and should pay attention to the treatment of the patients with streptococcal pharyngitis.

PURPOSE: To evaluate the cause and surgical outcome of extensor pollicis longus rupture after distal radius fractures. MATERIALS AND METHODS: Nineteen cases in which the patients underwent surgical treatment for rupture of the extensor pollicis longus after distal radius fractures were followed for more than one year. Among the nineteen cases, fourteen extensor pollicis longus ruptures occurred after conservative treatment, four occurred after closed reduction with K-wire fixation, and one occurred after open reduction and internal fixation with a plate. All cases were treated by extensor indicis proprius transfer. RESULTS: Extensor pollicis longus ruptures were caused by K-wire irritation in two, by a protruding screw tip in one, and by a callus in one. In the conservative treatment group, tendon ruptures were diagnosed at an average of 3.1 months (0.7~17). Tendon ruptures were detected in the surgical treatment group at an average of 12.8 months (1~48). All the patients showed favorable recovery of the extension capability of the thumb at the final follow-up. CONCLUSION: The main cause of extensor pollicis longus rupture after distal radius fracture was ischemic damage. Therefore, during the surgery, the length and direction of screws and K-wires should be fixed carefully to avoid such damage. Distal radius fracture also requires careful observation of the extensor pollicis longus during follow-up. Furthermore, extensor indicis proprius transfer is considered to be an effective method for extensor pollicis longus rupture.

A study for seroprevalence of Hepatitis B virus markers (HBsAg, Anti-HBs, HBeAg and Anti-HBe) by EIA method and the Liver Function Test(SGOT and SGPT) using kinetic method was carried :out from January; to October 1995 :among male workers of a .major iron and steel manufacturing company, located,,in Pohang. The results were as follows; 1. The distribution of hepatitis B virus markers showed that the proportions of HBsAg(+)/Anti-HBs (-), HBsAg(-)/Anti-HBs (+) 'and HBsAg(+)/Anti-HBs (+) were 8.1%, 60.5% and 0.1%, respectively. The positive rate of HBsAg in all subjects was 8.2% whereas that of anti-HBs was 60.6%. 2. The proportions of HBsAg(+)/Anti-HBs (-) and HBsAg(-)/Anti-HBs (+) increased significantly with age. While the distribution of hepatitis B virus markers exhibited no significant differences among the groups classified by educational background or work type. 3. The proportion of drinkers in HBsAg (+)/Anti-HBs (-) (73; 9%) was significantly lower than those of HBsAg (-)/Anti-HBs (-) and HBsAg (-)/Anti-HBs (+) (84.6% and 85.7% respectively). The proportions of smoking for the three groups of HBsAg (-)/Anti-HBs(+),-HBsAg (+)/Anti-HBs (-) and HBsAg (-)/Anti-HBs (-) were 54.3%, 53.7% and 53.0%, respectively (p<0.01). The proportion of the subjects with abnormal liver function test in HBsAg (+)/Anti-HBs (-) was 40.1%, whereas those in HBsAg (-)/Anti-HBs (-) and HBsAg(-)/Anti-HBs (+) were 21.9% and 18.4%, respectively. 4. The distribution of e Ag markers among HBsAg (+) subjects showed that the proportions of HBeAg(+)/Anti-HBe(-), HBeAg(-)/Anti-HBe(+) and HBeAg(+)/Anti-HBe(+) were 31.3%, 55.0% and 1.6%, respectively. The proportion of HBeAg(+)/Anti-HBe(-) decreased significantly with age and those of HBeAg(-)/Anti-HBe(-) and HBeAg(-)/Anti-HBe(+) increased with age. The positive rate of HBeAg among HBsAg (+) subjects was 32.9%. In conclusion, as a screening method, EIA is. recommended to test hepatitis B virus markers, especially when examining Anti-HBs more sensitively. For the workers of the iron and steel manufacturing company studied, liver diseases caused by other than hepatitis B should be given a special care including an education avoiding alcohol drinking.

PURPOSE: Fetal echocardiography is used for the prenatal diagnosis of congenital heart disease. Fetal echocardiography allows decisions to be made in advance where the fetal abnormality is not compatible with life after delivery or where early correction is required. Our fetal echocardiographic experience was analysed retrospectively to guide future clinical application. METHODS: 138 mothers had fetal echocardiography from April 1992 to December 1995. Their echo findings were recorded on VHS video tape. We followed up the infant after delivery. Data was collected from obstetric outpatient records and admission records, pediatric admission records and outpaitent records. RESULTS: 1)138 mothers had fetal echocardiography. Serious heart disease was found in 9 cases with a detection rate of 6.4%. Average age of the mother was 28.9+/-4.2 years (range 17-44 years). Average gestational period was 24.0+/-5.1 weeks(range 10-36 weeks). 2)Indications for fetal echocardiography were as follows; maternal factors 77 cases, including 34 cases of alpha fetoprotein abnormality. fetal factor 32 cases including 18 cases of arrhythmia, genetic factors 29 cases, including 26 cases of family history of congenital heart disease. 3)Serious cardiac anomalies were 5 cases. Serious arrhythmia were present in 4 cases(Total 9 cases with detection rate of 6.5%). Mild arrhythmia was detected in 7 cases(5.1 %). 4)The serious cardiac anomalies were mitral hypoplasia, right atrial tumor, AVSD, TOF and VSD. 5)The Serious arrhythmia were complete atrioventricular block 1 case, second degree atrioventricular block 1 case, transient cardiac arrest 1 case and atrial flutter 1 case. 6)The Mild arrhythmia were premature atrial contraction 4 cases and premature ventricular contraction 3 cases. 7)The non-cardiac anomalies were one case of hydrocephalus, cerebral arteriovenous fistula, diaphragmatic hernia, agenesis of right kidney, sacrococcygeal teratoma, fetal ascites and 4p-syndrome. There were 2 cases of spontaneous abortion without definite anomaly. During the study period, there were 8 terminations of pregnancy including 3 cases of spontaneous abortion. 8) 105 infants were followed up after birth. 25 cases were missing. CONCLUSIONS: Most of the congenital heart disease confirmed by fetal echocardiography was predicted by antenatal ultrasound. Most of the fetal echocardiography was performed to confirm the congenital heart diseas when any of the fetal abnoramlities were found. In some of the treatable heart disease, especially like fetal arrhythmia, maternal adminstration of adequate medication make a good treatment results.

Demodex mites are considered part of the normal skin flora. Typically, Demodex is harmless and causes no clinical symptoms. We present a 43-year-old woman with pruritic erythematous plaque and papulopustular eruptions on the right cheek. The patient was treated seborrheic dermatitis in face from several years ago. However, the lesion was aggravated after continuous topical steroid usage for several months at a local clinic. Histological examinations revealed Demodex mites in the follicular ostia with perivascular and perifollicular lymphohistiocytic inflammation. Treatment was initiated with metronidazole at a dose of 250 mg three times per day and then crotamiton ointment once daily. The lesion showed marked improvement after six weeks of treatment with mild residual erythema. The findings presented here indicate that Demodex infestation should be considered in the differential diagnosis of unilateral follicular eruptions of the face.
