Since the economic crisis in 1997, the number of low income families has increased and the turmoil is likely to affect nutritional and health status of the children in low-income families. The purpose of this study was to investigate dietary behaviors and physical development of low income family children in the Seoul area. The subjects were 44 boys and 56 girls, between the ages of 7 and 12 years, from the beneficiary families of the governmental assistant program and enrolled in after school-care centers. A self-reported questionnaire, including general characteristics and dietary behaviors, was applied to the children and their parents. Skipping meal rate was higher in breakfast than in lunch or dinner, and was less frequent in parents and children families compared to that of the other types of families (p<0.05). Most students are shown that they usually keep the dietary guideline for Korean children. There were significant differences in keeping the dietary guidelines between the parents and children family group and other groups in several items. The results imply that the nutrition education program should be more focused on the families which are not composed of parents and children.

Amniotic fluid embolism, one of the leading causes of maternal death, is a rare event, however, it can cause maternal death and neonatal morbidity when it unrecognized and untreated effectively. Its pathogenesis is unclear and clinical presentations are variable without standardized means of confirming diagnosis. We experienced one case of neonatal hypoxic ischemic encephalopathy possibly due to maternal amniotic fluid embolism, which was diagnosed by brain MRI, EEG and maternal uterine pathology. We report this case with a brief review of literatures.

Although excessive arteriovenous fistula blood flow may be a factor in the development of high-output cardiac failure, this diagnosis is easily over-looked. Surgical reduction of fistula blood flow can improve the condition. We here report a case of high-output cardiac failure due to excessive arterio-venous fistula blood flow in a hemodialysis patient. A 51-year-old man who had been treated with hemodialysis since 5 years ago was admitted for increasing cardiac failure. Echocardiographic evaluation of cardiac output and duplex measurement of the fistula confirmed the diagnosis of high-output cardiac failure due to excessive arteriovenous fistula blood flow. After surgical closure of the fistula, the signs and symptoms of cardiac failure subsequently subsided and both systolic and diastolic dimension of left ventricle much decreased.

Post-menopausal osteoporosis (PMO) is a major global human health concern. Owing to the need for therapeutic drugs without side effects, natural extracts containing various polyphenolic compounds that may exert estrogenic effects have been studied in depth. Rhus verniciflua Stokes (RVS), which has been used as a traditional herbal medicine for centuries in Korea, was recently revealed to exert estrogenic effects attributable to its bioactive ingredients sulfuretin and butein, which have strong estrogen receptor–binding affinities. In this study, the protective potential of RVS in PMO was evaluated by using an experimental animal model of PMO, which was established by ovariectomy (OVX) of female Sprague Dawley rats. The oral administration of RVS at 20 mg/kg or 100 mg/kg for 8 weeks markedly protected against OVX-induced atrophy of the uterine tube and reversed the elevation in the ratio of serum receptor activator of nuclear factor-κB ligand to osteoprotegerin, which is a marker of disease severity. In addition, RVS inhibited OVX-induced tibia bone loss, activated osteogenic activity, and suppressed osteoclastic activity in the tibial epiphyseal plate, a region of bone remodeling. Collectively, these factors indicated that the oral intake of RVS might be beneficial for the prevention of PMO.

PURPOSE: Internal mammary lymph node (IMLN) metastasis is an important prognostic indicator in breast cancer. However, the necessity of internal mammary sentinel lymph node biopsy for accurate staging, for choosing adjuvant treatment, and as a prognostic indicator, has remained controversial. METHODS: From January 2001 to December 2006, 525 female breast cancer patients underwent radical surgery after preoperative lymphatic scintigraphy. We retrospectively analyzed the follow-up results, recurrences, and deaths of all patients. RESULTS: There was no significant difference in the clinicopathological characteristics between the axilla and the IMLN groups. The median follow-up period was 118.8 months (range, 7-122 months) in the axilla group and 107.7 months (range, 14-108 months) in the IMLN group. During the median follow-up period, the breast cancer-related death rate in the axilla group was 3.6%, which was not significantly different from that of the IMLN group (1.3%) (p=0.484). The five-year survival rates did not differ between the two groups (p=0.306). The overall recurrence rate and the locoregional recurrence rate also did not differ between the two groups (p=0.835 and p=0.582, respectively). The recurrence rate of IMLN (both ipsilateral and contralateral) metastasis was very low, accounting for 0.5% in the axilla group and 1.3% in the IMLN group (p=0.416). CONCLUSION: The long-term follow-up results showed that there was no significant difference in both overall outcome and regional recurrence between the two groups. Therefore, the requirement for identification of nodal basins outside the axilla or IMLN sentinel biopsy should be reconsidered.

Absent right superior vena cava in visceroatrial situs solitus is rare. It has been known the absent right superior vena cava is usually accompanied with persistent left superior vena cava. And this anomaly could be combined witk additional congenital heart disease and rhythm disturbances. We experienced one case of absent right superior vena cava accompanied by persistent left superior vena cava, secundum type atrial septal defect, and transient post-operative sinus node dysfunction.

OBJECTIVE: Small cell carcinoma of the uterine cervix (SMCC) is extremely rare, and an aggressive disease that proliferates rapidly. It was often reported that the diagnostic accuracy of cytologic smears in diagnosing SMCC was low. This is a report of the Severance Hospital experience with the patients suffering from SMCC. METHODS: Twenty-seven patients with small cell carcinoma of the uterine cervix were diagnosed and treated at the Severance Hospital from November 1991 to January 2010. The data were analyzed retrospectively, based on the available charts and pathology reports. Various fields, such as chief complaints and symptoms present at first clinic visit, age, International Federation of Obstetrics and Gynecology (FIGO) clinical stage, treatment modality, the 5-year overall survival rate, and recurrence rate were investigated. RESULTS: Among the 27 patients diagnosed with small cell carcinoma of the uterine cervix, 18 of them (66.7%) presented with symptoms, including vaginal bleeding, at the first clinic visit, and the remaining 9 patients (33.3%) showed abnormal Pap smear screening in the process of their routine health check-up. The median age of the patients was 54 years (range, 24 to 77 years). FIGO stage IIB was the most common stage (11 of 27 patients). The 5-year overall survival rate of 21 patients, who could be followed up, was 57.2%. Six patients showed recurrence after remission, and the mean disease free interval of them was 9.2 months (range, 6 to 11 months). Abnormal Pap smear screening results of 9 patients was investigated, and the diagnostic accuracy of the cytologic findings was 22.2%. CONCLUSION: Our study was consistent with the concept that Pap smear screening might not be helpful in early diagnosis of SMCC considering its low diagnostic accuracy. Further large-scale multicenter prospective studies are definitely needed in order to produce abundant information about optimal therapy and diagnosis.

BACKGROUND: Recently, assessment of left anterior descending (LAD) coronary flow by transthorasic Doppler echocardiography (TTDE) has been emerged as a useful tool in evaluation of microcirculatory function of coronary circulation. The measuring site of coronary flow by TTDE is distal LAD. But it was not fully investigated whether the distal flow velocity is identical to that of proximal segment. The purpose of this study is to compare coronary blood flow velocity and coronary flow reserve (CFR) in normal LAD according to its level. METHOD: 9 patients (1 male, 8 females; mean age 52.8+/-11.1years) were included for this study. Coronary flow velocity was measured with intracoronary Doppler guide wire at the proximal (before first diagonal branch), mid (after second diagonal branch), and distal segments of LAD at baseline and after intracoronary bolus injection of 18 microgram adenosine. Baseline and hyperemic average peak velocity (APV) and CFR were compared between segment. RESULTS: Baseline and hyperemic APV appears to be diminished from proximal (24.6+/-3.5 cm/sec, 55.8+/-10.7 cm/sec) to distal (21.7+/-6.9 cm/sec, 49.7+/-17.2 cm/sec) LAD without statistical significance. But, CFR showed no significant difference in each segments (proximal, mid, and distal segment; 2.3+/-0.26, 2.3+/-0.32, 2.3+/-0.48, p=0.95). As the increment of peak systolic velocity (PSV) from baseline to hyperemic state was larger than that of peak diastolic velocity (PDV), diastolic to peak systolic velocity ratio (DSVR) was decreased significantly by hyperemic state in proximal and distal segment (baseline; 2.1+/-0.8, 2.1+/-0.5 vs hyperemia; 1.8+/-0.6, 1.7+/-0.3, p<0.05). CONCLUSION: Coronary blood flow velocity appears to be decreased from proximal to distal segment of normal LAD without statistical significance. There were no differences in CFR between proximal, mid and distal segment of normal LAD.

BACKGROUND: Several studies suggested that T-wave normalization (TWN) in exercise ECG indicates the presence of viable myocardium. But the clinical implication of this phenomenon in patients with acute myocardial infarction who received proper revascularization therapy was not determined. Precisely the aim of this study was to investigate the relationship between TWN in exercise ECG and myocardial functional recovery after acute myocardial infarction. METHODS: We studied 30 acute myocardial infarction patients with negative T waves in infarct related electrocardiographic leads and who had received successful revascularization therapy. Exercise ECG was performed 10 ~14days after infarct onset using Naughton protocol. Patients were divided into 2 groups according to presence (group I; n=14) or not (group II; n=16) of TWN in exercise ECG. Exercise parameters and coronary angiographic findings were compared between groups. Baseline and follow-up (mean 11 months) regional and global left ventricular function was analyzed by echocardiography. RESULTS: Exercise parameters were similar between groups. There was no difference in baseline ejection fraction and wall motion score between group I and II (EF; 56 +/- 12% vs 52 +/- 11%, p=ns. WMS; 21 +/- 3 vs 23 +/- 4, p=ns) and it was improved at the tenth month by similar magnitude (group I/group II, EF % change = 12 +/- 12% vs 7 +/- 6%, p=ns, WMS % change=6 +/- 6% vs 7+/- 5%, p=ns). The finding of no relation between TWN and functional recovery was observed also when the patients were analysed according to infarct location and presence or absence of Q-waves. CONCLUSION: As the exercise-induced TWN in patients with acute myocardial infarction was not related with better functional recovery of dysfunctional regional wall motion and ejection fraction, TWN does not appear to be an indicator of myocardial viability.

A persistent left superior vena cava(SVC) is found in about 0.3% of healthy individuals and 4.3% of patients with congenital heart disease. This anomaly is most frequently found in conjunction with a right-sided SVC, but may also be solitary. Recently, we experienced a case of persistent left SVC in patient with chronic renal failure. He required subclavian catheterization for hemodialysis due to leakage of peritoneal dialysate into external genitalia and pleural cavity. Because he had had a history of right subclavian catheterization for hemodialysis 3 months ago, the hemodialysis catheter was inserted in the left subclavian vein without any complication. Chest X-ray after insertion of the catheter showed that the distal tip of the catheter seemed to be within the aorta. Venography showed that the catheter was located within the left SVC and MRI showed isolated two SVC. He is receiving hemodialysis through the left subclavian catheter which is positioned within the left SVC without any problem.
