Background:
It is well known that a large number of patients with diabetes also have dyslipidemia, which significantly increases the risk of cardiovascular disease (CVD). This study aimed to evaluate the efficacy and safety of combination drugs consisting of metformin and atorvastatin, widely used as therapeutic agents for diabetes and dyslipidemia.
Methods:
This randomized, double-blind, placebo-controlled, parallel-group and phase III multicenter study included adults with glycosylated hemoglobin (HbA1c) levels >7.0% and <10.0%, low-density lipoprotein cholesterol (LDL-C) >100 and <250 mg/dL. One hundred eighty-five eligible subjects were randomized to the combination group (metformin+atorvastatin), metformin group (metformin+atorvastatin placebo), and atorvastatin group (atorvastatin+metformin placebo). The primary efficacy endpoints were the percent changes in HbA1c and LDL-C levels from baseline at the end of the treatment.
Results:
After 16 weeks of treatment compared to baseline, HbA1c showed a significant difference of 0.94% compared to the atorvastatin group in the combination group (0.35% vs. −0.58%, respectively; P<0.0001), whereas the proportion of patients with increased HbA1c was also 62% and 15%, respectively, showing a significant difference (P<0.001). The combination group also showed a significant decrease in LDL-C levels compared to the metformin group (−55.20% vs. −7.69%, P<0.001) without previously unknown adverse drug events.
Conclusion
The addition of atorvastatin to metformin improved HbA1c and LDL-C levels to a significant extent compared to metformin or atorvastatin alone in diabetes and dyslipidemia patients. This study also suggested metformin’s preventive effect on the glucose-elevating potential of atorvastatin in patients with type 2 diabetes mellitus and dyslipidemia, insufficiently controlled with exercise and diet. Metformin and atorvastatin combination might be an effective treatment in reducing the CVD risk in patients with both diabetes and dyslipidemia because of its lowering effect on LDL-C and glucose.

PURPOSE: Reduction-oxidation reaction homeostasis is vital for regulating inflammatory conditions and its dysregulation may affect the pathogenesis of chronic airway inflammatory diseases such as asthma. Peroxiredoxin-6, an important intracellular anti-oxidant molecule, is reported to be highly expressed in the airways and lungs. The aim of this study was to analyze the expression pattern of peroxiredoxin-6 in the peripheral blood mononuclear cells (PBMCs) of asthmatic patients and in bronchial epithelial cells (BECs).METHODS: The expression levels and modifications of peroxiredoxin-6 were evaluated in PBMCs from 22 asthmatic patients. Phosphorylated and acetylated peroxiredoxin-6 in hydrogen peroxide-treated human BECs was detected using immunoprecipitation analysis. The expression level of peroxiredoxin-6 was also investigated in BECs treated with hydrogen peroxide. Cycloheximide and proteasome inhibitors were used to determine whether peroxiredoxin-6 is degraded by proteasomes.RESULTS: Peroxiredoxin-6 expression was significantly reduced in the PBMCs of asthmatic patients compared to control subjects. Distinct modification patterns for peroxiredoxin-6 were observed in the PBMCs of asthmatic patients using 2-dimensional-electrophoresis. The levels of phosphorylated serine and acetylated lysine in peroxiredoxin-6 were significantly increased in the BECs following hydrogen peroxide treatment. The level of peroxiredoxin-6 expression was reduced in hydrogen peroxide-stimulated BECs, presumably due to proteasomes.CONCLUSIONS: The expression of peroxiredoxin-6, which is down-regulated in the immune cells of asthmatic patients and BECs, can be modified by oxidative stress. This phenomenon may have an effect on asthmatic airway inflammation.

PURPOSE: The causes of acute lower respiratory tract infection (ALRTI) are mostly attributable to viral infection, including respiratory syncytial virus (RSV), parainfluenza virus (PIV), influenza virus A/ B (IFV A/ B), or adenovirus (ADV). Several Korean studies reported human metapneumovirus (hMPV) as a common pathogen of ALRTI. However, studies on seasonal distribution and clinical differences relative to other viruses are insufficient, prompting us to perform this study. METHODS: From November 2006 to October 2007, we tested nasopharyngeal aspiration specimens in children hospitalized with ALRTI with the multiplex reverse transcriptase-polymerase chain reaction to identify 6 kinds of common pathogen (hMPV, RSV, PIV, IFV A/ B, and ADV). We analyzed positive rates and clinical features by retrospective chart review. RESULTS: We detected 38 (8.4%) hMPV-positive cases out of 193 (41.8%) virus-positive specimens among 462 patients. HMPV infection prevailed from March to June with incidence peaking in April. HMPV-positive patients were aged 1-5 years (76.3%), and the ratio of boys to girls was 1.2:1. The median age was 27 months. HMPV primarily caused pneumonia (76.3%) (P=0.018). Average hospitalization of HMPV-associated ALRTI patients was 5.8 days. In addition, they showed parahilar peribronchial infiltration (100%) on chest X-ray, normal white blood cell count (73.7%), and negative C-reactive protein (86.8%) (P>0.05). All hMPV-positive patients recovered without complication. CONCLUSION: HMPV is a common pathogen of ALRTI in Korean children, especially in 1-5 year olds, from March to May. Immunocompetent children diagnosed with hMPV-associated ALRTI may have a good prognosis.

Frozen shoulder is characterized by pain in the shoulder and limitation of glenohumeral movement. The underlying pathologic changes in frozen shoulder are synovial inflammation with subsequent reactive capsular fibrosis. Capsular fibrosis is the ultimate course of frozen shoulder suffering from various causes irrespectively. Therefore, adhesions that are affecting the joint movement must be released. Most important diagnostic method is thoughtful history taking and physical examination, and ultrasonography is very valuable device of diagnosis and treatment. Interventional microadhesiolysis and nerve stimulation (IMNS) is effective to manage frozen shoulder patients. IMNS for frozen shoulder is composed of three release approaches. These are (1) subacromial, (2) posterior inferior capsular, and (3) subdeltoidal & subcoracoidal release and round needle can be used for each release. We report this experiences and recommand this technique for the treatment of frozen shoulder patients.

Teratoma originate from one or more germ cell layer and commonly arise from sacrococcygeal area in neonate. Teratoma arising from the oropharyngeal cavity is called "epignathus tumor" and is extremely rare in neonate. Clinical manifestation of epignathus tumor vary from asymptomatic to severe respiratory distress symptom. It is reported that most of the tumor are benign in nature. Large teratoma can be diagnosed by prenatal ultrasonography, but most cases were diagnosed with computed tomography or magnetic resonance image after birth. Prognosis is determined by the need for neonatal resuscitation for respiratory distress at the time of birth and the extent of tumor, involving large vessles, skull base or communication with the brain. We experienced a case of epignathus tumor in a neonate with severe respiratory distress immediately after birth, so that reported with review of the literature.

Herpes zoster in infancy is very rare but can be developed following intrauterine or postnatal exposure to varicella zoster virus. We report a case of herpes zoster in a 4-month-old male infant. He had no prior history of primary varicella or varicella vaccination. His mother had no history of varicella infection and no contact history with varicella during pregnancy. He had a history of exposure to his father with herpes zoster 3 months ago, and to his cousin with convalescent chickenpox 2 months ago. Multinucleated, giant cells were shown on a Tzanck smear. He was treated with acyclovir and first generation cephalosporin for herpes zoster with Staphylococcal skin infection, with complete resolution without sequelae.

Midgut volvulus is commonly complicated with malrotation, and develops mainly in infants before 1 year old, especially in neonate. Intrauterine midgut volvulus is an extremely rare disease therefore is difficult to diagnose. Furthermore unless the fetus has malrotation, symptoms and results of tests suspicious of fetal midgut volvulus are nonspecific. There are some reports that meconium ileus could be a cause of intrauterine midgut volvulus from foreign countries, however has never been reported in Korea. So we report a case of prematurity born with bowel perforation and gangrene due to intrauterine midgut volvulus caused by meconium ileus.

PURPOSE: DNA methylation is an important epigenetic factor in tumorigenesis. We hypothesized that polymorphism of the promoter of the DNA methyltransferase 3b (DNMT3b) genes, which are responsible for regulating the methylation status of tumor suppressor genes, are associated with increased risk of gastric cancer. MATERIALS AND METHODS: In this hospital-based case-control study, to determine the role of this polymorphism of the promoter of DNA methyltransferase 3b (DNMT3b) genes in gastric cancer, we genotyped 176 cases and 70 control subjects. To determine the genotype, we used a polymerase chain reaction restriction fragment length polymorphism assay. We compared alleles and genotypes between the two groups and revealed an association of DNMT3b promoter polymorphism with increased risk of gastric cancer in the Korean population. RESULTS: Genotype frequencies were 14.8% (Cytosine-Cytosine), 71.6% (Cytosine-Thymine), and 13.6% (Thymine- Thymine) in the case patients and 40.0% (Cytosine-Cytosine), 42.9% (Cytosine-Thymine), and 17.1% (Thymine-Thymine) in the control subjects, respectively. Compared with CC homozygotes, CT heterozygotes had a 4.523-fold increased risk (OR, 2.13; 95% CI, 2.324~8.803), and the TT homozygotes had a 2.154-fold elevated risk (OR, 1.42; 95% CI, 0.899~5.165). For the T variant genotype (CT+TT), there was a 3.846-fold increased risk (OR, 1.88; 95% CI, 2.040~7.251). However, no significance was observed in the genotype distributions of both polymorphisms according to histopathology, stage of stomach cancer. The Ssame results were observed with Helicobacter infection. CONCLUSION: DNMT3b promoter polymorphism, especially the T variant genotype, is associated significantly with thean increased risk of gastric cancer.

Epidural anesthesia for cesarean section allows the mother to be awake, minimizes or completely avoids the problem of maternal aspiration and neonatal drug depression from general anesthetics. But epidural anesthesia has the potential to produce local anesthetic systemic toxicity or inadvertent high spinal block which is due to unintentional administration of drug into an epidural vessel or subarachnoid space. There are several ways to avoid these complications. These include careful aspiration of epidural catheter, fractionation of the epidural dose, and the use of epinephrine containing epidural test dose before injection of epidural dose. We report a case of a pregnant woman who had developed a seizure after an injection of the epidural anesthetic. This occurred despite using the techniques of aspiration and epinephrine containing epidural test dose injection. So we thought that the seizure occurred probably by the migration of epidural catheter while changing positions and it should be considered in all cases of epidural anesthesia.

PURPOSE: Kawasaki disease is a systemic vasculitis, leading cause of pediatric acquired heart disease. Vascular endothelial growth factor (VEGF) has functions as vascular permeability factor, plays an important role in coronary artery lesion (CAL). We studied the clinical significance of serum VEGF in Kawasaki disease. METHODS: Kawasaki group was 49 patients, and control group was 15 patients. Diagnosis followed AHA (American Heart Association) diagnostic criteria, with blood sampling in acute, subacute, and convalescent phase. Echocardiographic abnormalities were defined and the definition of intravenous gamma globulin (IVGG)-responsive and IVGG-resistant was determined. RESULTS: Serum VEGF of Kawasaki group was significantly higher than of control group. Comparison of serum VEGF between CAL and non-CAL group, between carditis group and non-carditis group showed no significant differences. Subacute serum VEGF was statistically higher in IVGG-resistant group than in IVGG-responsive group, and serum VEGF of IVGG-resistant group in subacute phase was statistically higher than in the other phases. Serum VEGF of convalescent CAL and non-CAL group in acute and subacute phase had meaningful differences. Total fever duration and subacute serum VEGF had positive correlation. Acute serum VEGF had positive correlation with ESR and CRP, all phases serum VEGF had also positive correlation with WBC. Acute and subacute serum VEGF had negative correlations with hemoglobin and albumin. CONCLUSION: Serum VEGF can help to determine the severity of Kawasaki disease, especially subacute serum VEGF seems to be used as a prognostic factor of coronary complication. Afterward, further studies needed with more strict diagnostic criteria and more study groups.
