Malposition of the extracorporeal membrane oxygenation (ECMO) venous cannula in the azygos vein is not frequently reported. We hereby present such a case, which occurred in a neonate with right-sided congenital diaphragmatic hernia. Despite ECMO application, neither adequate flow nor sufficient oxygenation was achieved. On the cross-table lateral chest radiograph, the cannula tip was identified posterior to the heart silhouette, which implied malposition of the cannula in the azygos vein. After repositioning the cannula, the target flow and oxygenation were successfully achieved. When sufficient venous flow is not achieved, as in our case, clinicians should be alerted so they can identify the cannula tip location on lateral chest radiograph and confirm whether malposition in the azygos vein is the cause of the ineffective ECMO.

Dentocutaneous fistula of the face neck is an infrequent manifestation of chronic dental infection. A periapical dental abscess may be initiated by disease, trauma, or thermal or chemical injury and develops into an extensive necrosis of surrounding tissue. Diagnostic errors can result in multiple excision, biopsies, and ineffective long-term antibiotic therapy. Awarness that periapical dental abscess is the most common etilolgic factor of cutaneous sinus tracts involves the face & neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. From 1994 to 1998, we have performed 6 cases of dentocutaneous fistula. Among of them, three were men and the others were women, age ranged from 18 to 66-year-old, and morbidity period was from 3 weeks to 3 years, the follow-up period ranged from 5 to 18 months (mean period 11 months). In conclusion, an understanding of the pathogenesis of cutaneous fistulae arising from dental infections will lead to proper early diagnosis and treatment without unnecessary surgery.

BACKGROUND: This study was carried out to examine the trends of government-supported health promotion research projects conducted in Korea over the past 12 years. METHODS: Research type, area of interest, organization, and expense of 726 research projects conducted from 1998 to 2009 were examined and the health promotion content analyzed. RESULTS: In Korea, 361 health policy researches (HPR) and 365 general health researches (GHR) were supported by the government during the defined time period. A total of 60.5 health promotion research were conducted annually with a total amount of 27.1 billion won provided (2.26 billion won per year). With the average research project lasting 8.5 months, HPR (7.7 months) projects were completed sooner than GHR (9.2 months). Those who majored in preventive medicine completed 177 research (24.4%), the most number of research projects, followed by public health (22.5%), and family medicine (15.6%). There were 641 health promotion research projects done mostly on policies, legal systems, and grasping current conditions, and only 85 (11.7%) clinical test research on the development or effects of health promotion programs. CONCLUSIONS: HPR have been increasing annually. However, our study could not be certain of how close the studies were to the government's health promotion policies. Furthermore, the main health promotion area, 'healthy living', was not researched as often as should be. Additionally, to improve applicability of the research projects, interdisciplinary cooperation should be promoted.

BACKGROUND: Oculocutaneous albinism (OCA) is a genetic disorder of the melanin pigment system in which melanin synthesis is reduced or absent in the skin, hair, and eyes. OCA is classified into two major types, and tyrosinase-related OCA can be produced by mutations of the structural gene for tyrosinase enzyme (TYR gene). OBJECTIVE: The purpose of this study was to analyze the segregation of mutant alleles of the TYR gene in tyrosinase-negative and tyrosinase-positive Korean OCA patients and families. METHODS: We amplified exon I, II, and III of the TYR gene of Korean OCA patients and their families by polymerase chain reactions (PCR), and analyzed the mutations by restriction fragment length polymorphism (RFLP) analysis in exon I and single-strand conformation polymorphism (SSCP) analyses in exon II and exon III. RESULTS: Two tyrosinase-negative cases showed mutations in exon I. Four tyrosinase-nega-tive cases and one tyrosinase-positive case showed mutations in exon II, and one tyrosinase-neg- ative case showed mutations in exon III. In summary, we found three kinds of mutation in four tyrosinase-negative OCA patients and one tyrsinase-positive OCA patient. CONCLUSIONS: RFLP and SSCP analysis can provide a basis for a rapid and sensitive screening system to detect TYR gene mutations of Korean OCA patients and their families.

We observed a case of sebaceous epithelioma associated with a nevus sebaceus in a 25-year-old male. The tumor was bean-sized, dome-shaped nodule on the slightly yellowish plaque of nevus sebaceus. Histopathological finding shows undifferentiated cells which are arranged in a palisade fashion at the periphery of a cell mass and a fairly large number of transitional cells and groups of mature sebaeeous cells.

Plasma cell cheilitis is a rare inflammatory disorder which shows a dense, band-like infiltrate of plasma cells in the upper dermis. Although the histological picture is shared with other diseases of the lips, plasma cell cheilitis is not associated with any known dermatoses. Some authors have shown the effectiveness of topical or intralesional corticosteroids; however, there have been many reports describing poor therapeutic response to topical steroids. We de-scribe two patients with plasma cell chielitis whose clinical condition responded rapidly to the intralesional injection of corticosteroids.

PURPOSE: In this study a systematic review and meta-analysis was used to examine the variables related to self-leadership in Korean clinical nurses. METHODS: A search and screening of the literature uncovered, 49 related studies done between 2003 and 2016 were then reviewed. A meta-analysis of 44 studies from doctoral dissertations, master's thesis and published articles was also carried out. The correlational effect size (ESr) for each related variable was calculated. RESULTS: Sixty-nine related variables were identified from the systematic review. Twenty-three (5 personal, 13 professional and 5 organizational) variables were eligible for meta-analysis. The overall effect size was .47. The personal factors (ESr=.48) and the professional factors (ESr=.44) had larger effect size than the organizational factors (ESr=.28). Factors with the largest effect size among personal, professional and organizational factors were self-efficacy (ESr=.58), nursing service (ESr=.68) and supervisor's leadership (ESr=.36) respectively. CONCLUSION: The results of this study show that for Korean clinical nurses individual factors including personal or professional factors have a stronger impact on self-leadership than organizational factors. It is necessary to develop interventions and training programs which focus on improving self-efficacy to promote self-leadership in clinical nurses.

OBJECTIVES: This study was conducted to examine the effects of mobile health (mHealth), using mobile phones as an intervention for weight loss in obese adults. METHODS: An electronic search was carried out using multiple databases. A meta-analysis of selected studies was performed. The effects of mHealth were analyzed using changes in body weight and body mass index (BMI). RESULTS: We identified 20 randomized controlled trials (RCTs) involving 2,318 participants who fit our inclusion criteria. The meta-analysis showed that body weight was reduced with a weighted mean difference (WMD) of −2.35 kg (95% confidence interval [CI], −2.84 to −1.87). An examination of the impact of duration of intervention showed that weight loss was greater after 6 months of mHealth (WMD = −2.66 kg) than between three and four months (WMD = −2.25 kg); it was maintained for up to 9 months (WMD = −2.62 kg). At 12 months, weight loss was reduced to a WMD of −1.23 kg. BMI decreased with a WMD of −0.77 kg/m2 (95% CI, −1.01 to −0.52). BMI changes were not statistically significant at 3 months (WMD = −1.10 kg/m2), but they were statistically significant at 6 months (WMD = −0.67 kg/m2). CONCLUSIONS: The use of mHealth for obese adults showed a modest short-term effect on body weight and BMI. Although the weight loss associated with mHealth did not meet the recommendation of the Scottish Intercollegiate Guideline Network, which considers a reduction of approximately 5 to 10 kg of the initial body weight as a successful intervention. Well-designed RCTs are needed to reveal the effects of mHealth interventions.

Cervical cancer and its precursors are caused principally, if not exclusively, by HPV infection and HPV DNA is found in more than 90% of cervical cancers. Cervical cytology is limited by its false negativity and this may be supplimented by other adjunctive test such as HPV test. It is therefore important to explore the use of HPV DNA detection as a primary or supplementary screening method and to determine whether HPV typing can be used as a predictor of a lesion's clinical behavior. Cervical cytology and Hybrid Capture test for HPV detection were performed in 450 asymtomatic wornen visited Health Care Center in Kangnam St. Mary's Hospital,and none of whom was believed to have current cervical disease. The Papanicolaou cytology results were classified by The Bethesda System : 333(74.%) women were classified to within normal limit, 19(4.2%) benign reactive change, 38(8.4%) ASCUS, 59(13%) low grade SIL, and only one woman high grade SIL. Twenty five of 450(5.6%) women showed HPV infection by Hybid Capture test. Among 98 wornen with abnormal Papanicolaou cytology, 16(16.3%) women showed HPV DNA positivity. (continue)
