Pseudopolycythemia is a situation in which a raised concentration of hemoglobin in circulating blood, with a red cell mass within normal range, while the plasma volume may be reduced in the absence of overt fluid loss. Relative, apparent, stress, or spurious polycythemia are commonly used synonyms for the same condition. It has been emphasized the association of pseudopolycythemia with hypertension, obesity, stress, and heavy cigarette smoking, especially in middle-aged men. We experienced 3 cases of pseudopolycythemia with several risk factors. They had complained of mild exertional dyspnea, palpitation, dizziness, and paresthesia of extremities. These symptoms were successfully relieved by stress reduction, stopping of smoking, and abstaining from drinking.

Toothpicks are not uncommonly swallowed, and subsequently, may be impacted into gastrointestinal wall and cause morbidities, and even mortality. Therefore, the early diagnosis and immediate retrieval of an ingested toothpick is important. In many cases, endoscopic removal is attempted initially, but if this fails or a complication is encountered, surgery should be considered. The authors experienced a case of ingested toothpick penetrating the gastric wall. A 51-year-old woman visited our hospital with epigastric pain of one-week duration. Upper endoscopy revealed that the sharp end of a toothpick had been impacted into the distal antrum. Endoscopic removal using an alligator jaw forceps failed because the toothpick broke during removal and our continued attempts to extract the remnant resulted in it becoming more embedded in the stomach wall. In such circumstances, surgical treatment should be considered. However, we incised the mucosa to expose the remnant toothpick, and fortunately, we were then able to grasp and remove the toothpick using an alligator jaw forceps. We report this unusual case of a toothpick impacted in the gastric wall that was resolved endoscopically by mucosal incision.

PURPOSE: This study was aimed to evaluate the clinical features of seizures in breastfed children with vitamin D deficient rickets. METHODS: Seventeen children, breastfed and diagnosed as vitamin D deficient rickets at Inha University Hospital from January 2000 to July 2010, were retrospectively investigated. Subjects were divided into two groups according to the presence/absence of seizures. Demographic and biochemical results were compared and statistically analyzed between the two groups, and the relative risk for seizure occurrence was estimated. Clinical features of seizures were also analyzed. RESULTS: Out of the 17 subjects, nine patients (53.0%) had seizures, while eight patients (47.0%) did not. The mean age for the two groups were 4.1+/-2.0 months and 9.3+/-2.7 months, respectively, which was statistically different between the two groups (P<0.0001). Serum calcium (Ca) and 25-hydroxyvitamin D3 (25-OHD3) levels were significantly lower in the 'seizure' group (5.7+/-1.0 vs. 9.5+/-0.9 mg/dL, P<0.0001; 5.7+/-0.8 vs. 15.3+/-4.2 IU/L, P<0.0001). The relative risk for seizure occurrence was 8 times higher in hypocalcemia and 17 times higher in 25-OHD3<8 ng/mL. Seizures occurred several times as generalized or focal types, but none of them developed epilepsy nor showed developmental abnormalities later on. CONCLUSION: Seizures in breastfed children with vitamin D deficiency rickets are mainly due to hypocalcemia, which is affected by 25-OHD3 levels. Seizures may also occur more frequently in children in the stages of rapid growth. Although seizures occurred multiple times, future outcomes were favorable. Further large-scaled prospective studies are required in the future.

The purpose of this study was to investigate the effects of wax gourd on weight, triglyceride, leptin and fat cell size in rats fed a high-fat diet. Male Sprague Dawley rats were fed an experimental diet containing total dietary fat at 40% of calories with wax gourd 0%, 5%, 10% and 15% (w/w) for 4 weeks. Weight gain and triglyceride level fell significantly in the 15% wax gourd group compared to the control group. Epididymal fat pad, abdominal fat and perirenal fat tended to decrease in the 15% wax gourd group. Leptin and free fatty acid level were not significantly different among the groups. Fat cell size significantly decreased in the 10% and 15% wax gourd groups compared to the control group. Weight gain correlated positively with visceral fat masses and the levels of leptin and triglyceride. Fat cell size significantly correlated with visceral fat and leptin level. Therefore, the 15% wax gourd diet substantially reduced weight, triglyceride and fat cell size.

OBJECTIVES: Infection and replication of the hepatitis B virus are closely related to the host immunity. Anticancer chemotherapy decreases the immune response of the host, Especially, glucocorticoid can activate the replication of hepatitis B virus directly. It is well known that hepatitis B virus infection and hepatic complications are more common in patients with hematologic malignancies like malignant lymphoma. We studied the incidence of hepatitis B virus infection and hepatic complications following anti-cancer chemotherapy in patients with malignant lymphoma. METHODS: Among 224 cases diagnosed as malignant lymphoma from January 1989 to December 1993 at Yonsei University Medical Center, 77 cases tested for hepatitis B virus serology was studied. RESULTS: 1) Eighteen cases (23%) was HBsAg positive. 2) The results of hepatitis C virus serology in six cases were all negative. 3) Eight (57%) of 14 follow-up cases had hepatic complications, Two patients had fulminant hepatitis, two nonicteric hepatitis and four icteric hepatitis. 4) Interferon-alpha was administered in three cases among the patients with hepatic complications. Loss of HBeAg was observed in one case and loss of HBsAg in another case. CONCLUSION: Serious hepatic complications can be occurred following anticancer chemotherapy in HBsAg-positive patients with malignant lymphoma. Therefore, we recommend that patients being considered as candidates for anticancer chemotherapy should routinely undergo serologic test for Hepatitis B virus. In addition HBsAg-positive patients with anticancer chemotherapy should be regularly monitored for hepatic injury. And with the careful use of steroid and interferon, prolongation of survival might be searched for these patients.

Although it has been shown that the percentage of bone marrow blasts in myelodysplastic syndrome (MDS) constitute the only independent determinant of survival and progression to acute leukemia, the great variability in survival among patients with MDS of similar percentage of blasts has prompted us to investigate new objective, independent prognostic parameters for the selection of high-risk patients. It was suggested that CD34 antigen expression adversely affected the prognosis of acute myelogenous leukemia. However, no study has been published so far on clinical and prognostic significance of CD34 antigen expression in MDS. Bone marrow biopsies from 58 patients diagnosed as primary MDS were studied using QBEND/10, a monoclonal antibody which recognized the human progenitor CD34 antigen on routine aldehyde-fixed, paraffin-embedded samples. The high percentage of CD34-positive cells (above 3% of total bone marrow nucleated cells) was predominantly observed in cases with RAEB-T, CMML, and to a lesser degree in RAEB. But neither age, hemograms, bone marrow findings including percentage of blasts, ALIP, nor leukemic transformation correlated with the percentage of CD34-positive cells. The median actuarial survival time in the high positive group was significantly shorter (12.0 months) than that of the low group (30.0 months; p = 0.028). The high CD34 aggregate (> or = 3) was selectively found in cases with RAEB, RAEB-T, and CMML. The percentage of bone marrow blasts (p = 0.007) and ALIP (p = 0.030) significantly correlated with number of CD34 aggregates.

BACKGROUND: Impaired lung function is associated with mortality rate from cardiovascular and all other death causes. There were previous studies on the relationship between lung function impairment and metabolic syndrome, but they are insufficient. This study was conducted on Koreans to analyze each component of metabolic syndrome as well as its variability between sexes. METHODS: 1,370 subjects underwent a health examination at the Eulji General Hospital Health Center. We examined the association between lung function measurement (forced expiratory volume for 1 second [FEV1], forced vital capacity [FVC], FEV1/FVC) and metabolic syndrome using Student t-test, Pearson partial correlation coefficient, and analysis of covariance for statistical analysis, and we adopted metabolic syndrome defined by American Heart Association/National Heart, Lung, and Blood Institute in Asia. RESULTS: Men with metabolic syndrome tended to experience lung function impairment. In terms of association to each metabolic syndrome component, metabolic syndrome components in men were associated with pulmonary function impairment and the more metabolic syndrome diagnostic criteria factors the patients had, the more severe their pulmonary function tended to decline. In women, waist circumference, triglyceride and high-density lipoprotein cholesterol were associated with pulmonary function change. CONCLUSION: In men, all metabolic syndrome components were associated with pulmonary function impairment, and the more metabolic syndrome components men had, the more severe their pulmonary functions decline. In women, components of metabolic syndrome were not associated with pulmonary function impairment.
