Background:
and purpose Whether pharmacologically altered high-density lipoprotein cholesterol (HDL-C) affects the risk of cardiovascular events is unknown. Recently, we have reported the Prevention of Cardiovascular Events in Asian Patients with Ischaemic Stroke at High Risk of Cerebral Haemorrhage (PICASSO) trial that demonstrated the non-inferiority of cilostazol to aspirin and superiority of probucol to non-probucol for cardiovascular prevention in ischemic stroke patients (clinicaltrials.gov: NCT01013532). We aimed to determine whether on-treatment HDL-C changes by cilostazol and probucol influence the treatment effect of each study medication during the PICASSO study.
Methods:
Of the 1,534 randomized patients, 1,373 (89.5%) with baseline cholesterol parameters were analyzed. Efficacy endpoint was the composite of stroke, myocardial infarction, and cardiovascular death. Cox proportional hazards regression analysis examined an interaction between the treatment effect and changes in HDL-C levels from randomization to 1 month for each study arm.
Results:
One-month post-randomization mean HDL-C level was significantly higher in the cilostazol group than in the aspirin group (1.08 mmol/L vs. 1.00 mmol/L, P<0.001). The mean HDL-C level was significantly lower in the probucol group than in the non-probucol group (0.86 mmol/L vs. 1.22 mmol/L, P<0.001). These trends persisted throughout the study. In both study arms, no significant interaction was observed between HDL-C changes and the assigned treatment regarding the risk of the efficacy endpoint.
Conclusions
Despite significant HDL-C changes, the effects of cilostazol and probucol treatment on the risk of cardiovascular events were insignificant. Pharmacologically altered HDL-C levels may not be reliable prognostic markers for cardiovascular risk.

BACKGROUND/AIMS: Gallbladder polyps (GBP) are a common clinical finding and may possess malignant potential. We conducted this study to determine whether visceral obesity is a risk factor for GBP. METHODS: We retrospectively reviewed records of subjects who received both ultrasonography and computed tomography with measurements of the areas of visceral adipose tissue and total adipose tissue (TAT) on the same day as health checkups. RESULTS: Ninety-three of 1,615 subjects (5.8%) had GBP and were compared with 186 age- and sex-matched controls. VAT (odds ratio [OR], 2.941; 95% confidence interval [CI], 1.325 to 6.529; p=0.008 for the highest quartile vs the lowest quartile) and TAT (OR, 3.568; 95% CI, 1.625 to 7.833; p=0.002 for the highest quartile vs the lowest quartile) were independent risk factors together with hypertension (OR, 2.512; 95% CI, 1.381 to 4.569; p=0.003), diabetes mellitus (OR, 2.942; 95% CI, 1.061 to 8.158; p=0.038), hepatitis B virus positivity (OR, 3.548; 95% CI, 1.295 to 9.716; p=0.014), and a higher level of total cholesterol (OR, 2.232; 95% CI, 1.043 to 4.778; p=0.039 for <200 mg/dL vs > or =240 mg/dL). Body mass index and waist circumference were not meaningful variables. CONCLUSIONS: Visceral obesity measured by VAT and TAT was associated with GBP irrespective of body mass index or waist circumference.

BACKGROUND/AIMS: Proton pump inhibitor (PPI) is generally prescribed to prevent post endoscopic submucosal dissection (ESD) bleeding. However, there was no consensus about the effectiveness of intravenous (IV) or oral PPI. We conducted this investigation to evaluate whether oral PPI can be also safely and effectively used to prevent post-ESD bleeding by measurement of intragastric pH. MATERIALS AND METHODS: Patients were assigned in the fixed order to IV pantoprazole by 40 mg every 12 hours and oral lansoprazole fast disintegrating tablet (LFDT) by 30 mg every 8 hours. We checked intragastric pH and hemoglobin (Hb) levels at pre and post-ESD procedure. RESULTS: A total of 10 patients (LFDT group: 6 patients, IV pantoprazole group: 4 patients) were included. There was no difference of baseline Hb level between two groups (LFDT, 14.38+/-0.46 mg/dL; IV pantoprazole, 13.85+/-0.83 mg/dL; P=0.18). After 24 hours, change of Hb level was not different between LFDT (0.95+/-0.30 mg/dL) and IV pantoprazole group (0.98+/-0.45 mg/dL; P=0.96). Baseline intragastric pH was 3.72+/-0.19 with LFDT and 4.31+/-0.41 with IV pantoprazole group (P=0.18). After 24 hours, there was no significant difference of the extent of pH increase between LFDT (2.38+/-0.28) and IV pantoprazole group (2.17+/-0.21; P=0.60). CONCLUSIONS: There was no difference in both the increase of post-24 hour intragastric pH and decrease of post-24 hour Hb between LFDT and IV pantoprazole group. Oral PPI regimen may be able to replace IV PPI therapy for the prevention of post-ESD bleeding and LFDT might be superior to IV PPIs in the aspect of cost-effectiveness.

As the government has a plan to terminate medical internships and to start the New Resident program, postgraduate medical students should encounter the new residency training program without the internship from 2015. To keep pace with this significant change, the Korean Neuropsychiatry association launched the task force team to manage this problem. The task force team has examined the psychiatry residency training programs from major countries, including England, Japan, Germany, Australia, New Zealand, and the Unites States. In addition, we conducted a survey for teaching psychiatrists and psychiatry residents who just finished the Psychiatry Board Examination in 2013 using a premade questionnaire on the expected problems that might occur if the internship program were abolished, and some significant issues regarding resident rotation schedule to other departments. In this paper, we summarized the results of our examination and survey. Establishment of a new residency training program based on these surveys would be desirable.

We report a case of primary mucosa-associated lymphoid tissue (MALT) lymphoma in the esophagus that manifested as a large submucosal tumor (SMT). Primary esophageal lymphoma is very rare, occurring in less than 1% of all patients with gastrointestinal lymphoma. Only a few cases of MALT lymphoma in the esophagus have been reported in the English literature. A 53-year-old man was referred to Dongguk University Ilsan Hospital (Goyang, Korea) in July 2012 for further evaluation and treatment of an esophageal SMT. Endoscopy showed a cylindrically elongated submucosal mass with normal overlying mucosa in the mid esophagus, 25-30 cm from the incisor teeth. He underwent surgery to confirm the diagnosis. Pathologic findings showed diffuse small atypical lymphoid cells which were stained with Bcl-2, CD20, but not with CD3, CD5, CD23, Bcl-6, or cyclin D1. These cells showed a positive monoclonal band for immunoglobulin heavy chain gene rearrangement. Based on the pathological, immunohistochemical, and molecular biological features, the esophageal mass was diagnosed as extranodal marginal zone B-cell lymphoma of the MALT type.

PURPOSE: Recently, Forkhead box M1 (FoxM1) was reported to be correlated with lung maturation and expression of surfactant proteins (SPs) in mice models. However, no study has been conducted in rabbit lungs despite their high homology with human lungs. Thus, we attempted to investigate serial changes in the expressions of FoxM1 and SP-A/B throughout lung maturation in rabbit fetuses. MATERIALS AND METHODS: Pregnant New Zealand White rabbits were grouped according to gestational age from 5 days before to 2 days after the day of expected full term delivery (F5, F4, F3, F2, F1, F0, P1, and P2). A total of 64 fetuses were enrolled after Cesarean sections. The expressions of mRNA and proteins of FoxM1 and SP-A/B in fetal lung tissue were tested by quantitative reverse-transcriptase real-time PCR and Western blot. Furthermore, their correlations were analyzed. RESULTS: The mRNA expression of SP-A/B showed an increasing tendency positively correlated with gestational age, while the expression of FoxM1 mRNA and protein decreased from F5 to F0. A significant negative correlation was found between the expression levels of FoxM1 and SP-A/B (SP-A: R=-0.517, p=0.001; SP-B: R=-0.615, p<0.001). CONCLUSION: Preterm rabbits demonstrated high expression of FoxM1 mRNA and protein in the lungs compared to full term rabbits. Also, the expression of SP-A/B was inversely related with serial changes in FoxM1 expression. This is the first report to suggest an association between FoxM1 and expression of SP-A/B and lung maturation in preterm rabbits.

Matched sibling bone marrow transplantation (BMT) in severe aplastic anemia (SAA) has been known as the treatment of choice in children and young adults. To overcome graft failure, second stem cell transplantation showed good results in previous studies. Here we report two cases of aplastic anemia patients with late graft failure and resulted in successful complete recovery after selective CD34+ cell boost infusion. The patients previously underwent allogeneic BMT from HLA-matched sibling donors and the engraftment was achieved although their CBC started to decrease respectively 3 months and 11 months after transplantation. Both patients received selective CD34+ cell infusion without additional conditioning therapy. Their CBC showed significant improvement and they are doing well without transfusion or complications. From this study we suggest that selected CD34+ cell boost treatment can be a promising curative treatment for late graft failure after matched sibling BMT in SAA patients.
