BACKGROUND: Cadmium is a toxic element in cigarette smoke associated with ischemic vascular disease. Its association with cerebral aneurysm is unknown. METHODS: We retrospectively analyzed the medical records of patients with headache who underwent imaging studies between March 2014 and August 2016. An unruptured intracranial aneurysm (UIA) was confirmed by brain magnetic resonance angiography or computed tomography angiography. A control group included age- and sex-matched patients without an UIA. Whole blood and random urine tests were used for detection of cadmium and arsenic levels, respectively. Student t-test was used to compare subject characteristics, mean cadmium and arsenic levels between groups, and differences between groups with small (<4-mm) and large (≥4-mm) UIAs. Multivariate regression analysis was used to identify risk factors for aneurysm incidence. RESULTS: Of 238 patients, 25 had an UIA. Those with an UIA had more pack-years of smoking (19.5±3.8 vs. 12.5±6.8, P=0.044) and higher mean serum cadmium levels (1.77±0.19 vs. 0.87±0.21 µg/L, P=0.027). Arsenic levels showed no difference between groups. (67.4±23.5 vs. 62.2±18.3 µg/L, P=0.458). There were no significantly different demographic, clinical, or laboratory characteristics between small and large aneurysm groups. According to multivariate analysis, smoking (odds ratio [OR], 1.48; 95% confidence interval [CI], 1.06–2.33; P=0.047) and serum cadmium >2.0 mcg/L (OR, 1.39; 95% CI, 1.15–1.84; P=0.043) were associated with aneurysm incidence. CONCLUSION: UIA incidence was associated with pack-years of smoking and serum cadmium level, but aneurysm size was not associated with serum cadmium level.

OBJECTIVES: Stress is considered a causal factor in many diseases, allergic disease being one of them. The prevalence of allergic disease is increasing in Korea, but the relationship between allergic symptoms and stress is not empirically well known. We aimed to evaluate the relationship between allergy-related symptoms and stress in children and adolescents. METHODS: We investigated 698 children and adolescents living in Gwangyang Bay, Korea, using a multi-stage cluster sampling method. Using the International Study of Asthma and Allergies in Childhood and the Psychosocial Well-being Index, these subjects were surveyed on allergy-related symptoms and psychosocial stressors in their lives, respectively. We used a multivariate logistic analysis for odds ratios for the complaint rate of allergic symptoms, after adjusting for age, gender, household income, body mass index, and residence. RESULTS: After adjustments, lifetime rhinitis (odds ratio [OR], 1.024), rhinoconjunctivitis (OR, 1.090), diagnosis of itchy eczema (OR, 1.040), treatment of itchy eczema (OR, 1.049), 12-month allergic conjunctivitis (OR, 1.026), diagnosis of allergic conjunctivitis (OR, 1.031), and treatment of allergic conjunctivitis (OR, 1.034) were found to be significantly associated with stress. CONCLUSIONS: Our results support the notion that there is a relationship between stress and allergic symptoms in children and adolescents. Further research into any causal relationship between stress and allergies, as well as preventative public health plans for decreasing stress in children and adolescents are needed.

BACKGROUND: Recently, the prevalence of colorectal cancer related with metabolic syndrome is increasing in Korea. The aim of this study was to reveal a relationship between components of metabolic syndrome and the development of colon polyp. METHODS: Among the subjects who visited a health promotion center of one university hospital and underwent colonoscopic examination from February 2010 to February 2011, a total of 1,630 (males 1,156, females 474) asymptomatic adults were included for the study. Sex, age, body mass index, waist circumference, blood pressure, fasting blood glucose, total cholesterol, triglyceride, HDL-cholesterol levels and the presence of colorectal polyps were measured. Alcohol consumption, smoking and exercise were assessed by a self-administered questionnaire. Metabolic syndrome was defined by criteria of 2004 American Heart Association/Updated NCEP Adult Treatment Panel III. RESULTS: The prevalence of colon polyps and metabolic syndrome was 21.7% and 16.0% respectively among study subjects. After adjustment for sex and age, metabolic syndrome (odds ratio [OR]=1.72, 95% confidence interval [CI] 1.05-2.82, P=0.031) and waist circumference (OR=1.04, 95% CI 1.01-1.06, P=0.009) were associated with increased risk of colorectal polyps. CONCLUSION: Metabolic syndrome and waist circumference were associated with increased risk of colon polyps in asymptomatic Korean adults.

BACKGROUND: Epidemiological studies suggest that serum calcium levels correlate with cardiovascular events. An ankle-brachial index (ABI) between 0.9 and 1.00 is a surrogate estimation of preclinical peripheral arterial disease (PAD). Prior studies have shown that an ABI of 0.9–1.0 is also associated with endothelial dysfunction. Therefore, we sought to investigate the relationship between serum calcium levels and preclinical PAD in apparently healthy Korean individuals. METHODS: We evaluated the association between serum calcium levels and preclinical PAD in 596 participants (334 males, 262 females) in a health examination program. Preclinical PAD was defined by an ABI of 0.9–1.0. Multiple logistic regression analysis was used to determine whether the serum calcium level was an independent determinant of preclinical PAD. RESULTS: The overall prevalence of preclinical PAD was 14.3%. The mean age was 44.0±12.5 years in the non-PAD group and 48.3±11.4 years in the preclinical PAD group (P=0.001). After adjusting for age, gender, systolic blood pressure, fasting plasma glucose, high-density lipoprotein cholesterol, triglycerides, C-reactive protein, g-glutamyltransferase, uric acid, hypertension medication, diabetes medication, and hyperlipidemia medication, the odds ratio (95% confidence intervals) for preclinical PAD was 2.28 (1.02–5.11) with a 1-mg/dL increase in the serum calcium. CONCLUSION: These findings suggest that increased serum calcium is independently and positively associated with preclinical PAD regardless of the presence of classic cardiovascular risk factors.

To investigate whether VacA (vacuolating toxin) produced by Helicobacter pylori Korean stain 99 induces intestinal secretion, purified VacA was added to T84 cell monolayers mounted in Ussing chambers, and electrical parameters were monitored. Mucosal addition of low pH-pretreated VacA increased short circuit current (Isc). The effect was time- and dose-dependent and saturable. The time-to-peak Isc was concentration-dependent. Chloride channel inhibitors, niflumic acid or 5- nitro-2- (3-phenylpropylamino) -benzoate (NPPB), inhibited VacA-stimulated Isc. Carbachol (CCh) -induced increase of Isc was prolonged by the addition of VacA to the mucosal side only. The effect was unaltered by the addition of niflumic acid. VacA did not show cytopathic effects. These studies indicate that VacA is a nonlethal toxin that acts in a polar manner on T84 monolayers to potentiate Cl secretion and the response to CCh secretion without decrease in monolayer resistance. VacA may contribute to diarrhea diseases in human intestinal epithelial cells.

OBJECTIVETo clarify if programmed cell death mechanisms induced by seizures take part in the necrotic process of neurons.

METHODSSeizure was induced by pilocarpine (P) in Sprague-Dawley adult rats which were allowed to recover for 24 or 72 hours before perfusion-fixation. Neuronal death was assessed by light microscopy with the hematoxylin-eosin (HE) staining and with in situ terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL). Bax and Bcl-2 protein expression were examined by histochemistry.

RESULTSTwenty-four and 72 hours after seizures, neuronal death in hippocampus CA1 region was morphologically necrotic. TUNEL-positive and morphologically necrotic cells increased in the hippocampal CA1 region at 72 hours after seizures, there was significant difference compared with controls (P < 0.001). Bax expression was also increased in the hippocampal CA1 region at 72 hours after seizures (P < 0.001), but Bcl-2 expression did not increase, while Bcl-2/Bax ratio decreased.

CONCLUSIONSeizures induced late-onset neuronal necrosis was accompanied by programmed cell death mechanisms.

A 53-year-old woman presented with asymptomatic pedunculated mass on her buttock. She was attacked by the tick while climbing the Jungbyung mountain located in Changwon City, the southern coastal area of the Korean Peninsula. It was identified as male Amblyomma testudinarium according to its morphological characteristics. Histological examination showed dense inflammatory infiltration of neutrophils and eosinophils, and dilated vessels on the dermis beneath the biting site of the tick. There have been only few reports of the tick bite by A. testudinarium in the Korean literature. To the best of our knowledge, our patient is the second case of tick bite from this species and the first tick bite from the male tick recorded in Korea. Here, we report a case of tick bite by male A. testudinarium in a woman, including a review of relevant literature.

PURPOSE: The aim of this retrospective study was to evaluate the influence of implant diameter, length and placement to implant stability. MATERIALS AND METHODS: Total 90 implants (US II plus(TM), Osstem co, Busan, Korea) of 72 patients were determined as experimental samples. The factors of diameters(o 4 mm, o 5 mm), lengths (10 mm, 11.5 mm, 13 mm), and implant placement (maxilla, mandible) were analyzed. The stability of the implants was measured by resonance frequency analysis (RFA) at the time of implant placement and impression taking. The difference of ISQ values according to patient's gender was evaluated by Independent t-test. ISQ values were compared between implant diameter, length and placement using one-way ANOVA and Tukey HSD test (alpha=.05). To compare ISQ values between at the time of surgery and impression taking, paired t-tests were used (alpha=.05). RESULTS: The change of implant length did not show significant different on the ISQ value (P>.05). However, 5 mm diameter implants had higher ISQ values than 4 mm diameter implants (P<.05). Implants placed on the mandible showed significantly higher ISQ values than on the maxilla (P<.05). CONCLUSION: In order to increase implant stability, it is better to select the wider implant, and implants placed on mandible are possible to get higher stability than maxilla. ISQ values at impression taking showed higher implant stability than ISQ values at implant placement, it means that RFA is clinically effective method to evaluate the change of implant stability through the osseointegration. The consideration of the factors which may affect to the implant stability will help to determine the time of load applying and increase the implant success rate.
