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.

Background:
Because the etiologies of bronchiectasis and related diseases vary significantly among different regions and ethnicities, this study aimed to develop a diagnostic bundle for bronchiectasis in South Korea.
Methods:
A modified Delphi method was used to develop expert consensus statements on a diagnostic bundle for bronchiectasis in South Korea. Initial statements proposed by a core panel, based on international bronchiectasis guidelines, were discussed in an online meeting and two email surveys by a panel of experts (≥70% agreement).
Results:
The study involved 21 expert participants, and 30 statements regarding a diagnostic bundle for bronchiectasis were classified as recommended, conditional, or not recommended. The consensus statements of the expert panel were as follows: A standardized diagnostic bundle is useful in clinical practice; diagnostic tests for specific diseases, including immunodeficiency and allergic bronchopulmonary aspergillosis, are necessary when clinically suspected; initial diagnostic tests, including sputum microbiology and spirometry, are essential in all patients with bronchiectasis, and patients suspected with rare causes such as primary ciliary dyskinesia should be referred to specialized centers.
Conclusion
Based on this Delphi survey, expert consensus statements were generated including specific diagnostic, laboratory, microbiological, and pulmonary function tests required to manage patients with bronchiectasis in South Korea.

Pheochromocytoma and paraganglioma (PPGLs) are rare catecholamine-secreting neuroendocrine tumors but can be life-threatening. Although most PPGLs are benign, approximately 10% have metastatic potential. Approximately 40% cases are reported as harboring germline mutations. Therefore, timely and accurate diagnosis of PPGLs is crucial. For more than 130 years, clinical, molecular, biochemical, radiological, and pathological investigations have been rapidly advanced in the field of PPGLs. However, performing diagnostic studies to localize lesions and detect metastatic potential can be still challenging and complicated. Furthermore, great progress on genetics has shifted the paradigm of genetic testing of PPGLs. The Korean PPGL task force team consisting of the Korean Endocrine Society, the Korean Surgical Society, the Korean Society of Nuclear Medicine, the Korean Society of Pathologists, and the Korean Society of Laboratory Medicine has developed this position statement focusing on the comprehensive and updated diagnosis for PPGLs.

PURPOSE: The development of bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic stem cell transplantation (HSCT) deteriorates patients' quality of life. This study aimed to analyze the prevalence, clinical features, risk factors and prognostic factors of BOS. MATERIALS AND METHODS: This retrospective study included patients who underwent allogeneic HSCT from January 2002 to December 2008 and survived for > or =100 days after transplantation. RESULTS: Of 860 patients who survived for > or =100 days, 36 (4.2%) met the diagnostic criteria. The duration of BOS development after transplantation was 466.00 (284.00-642.75) [median (interquartile range)] days. The risk factor for the development of BOS was peripheral blood as the stem cell source with a hazard ratio (HR) of 2.550 [95% confidence interval (CI): 1.274-5.104, p=0.008]. In multivariate analysis, pretransplant FEV1/FVC (HR: 0.956, 95% CI: 0.921-0.993, p=0.020) and time from HSCT to diagnosis of BOS (HR: 0.997, 95% CI: 0.994-0.999, p=0.009) were independent prognostic factors associated with mortality. CONCLUSION: Peripheral blood as a stem cell source is a risk factor for the development of BOS. A decreased pretransplant FEV1/FVC and shorter duration of time from transplantation to diagnosis of BOS are poor prognostic factors for BOS.

Pelvic inflammatory disease (PID), which is one of the most problematic complications experienced by women with sexually transmitted diseases, frequently causes secondary infections after reproductive abnormalities in veterinary animals. Although the uterus is self-protective, it becomes fragile during periods or pregnancy. To investigate PID, bacteria or lipopolysaccharide (LPS) extracted from gram negative bacteria has been used to induce the disease in several animal models. However, when LPS is applied to the peritoneum, it often causes systemic sepsis leading to death and the PID was not consistently demonstrated. Hydrochloric acid (HCl) has been used to induce inflammation in the lungs and stomach but not tested for reproductive organs. In this study, we developed a PID model in mice by HCl and LPS sequential intracervical (i.c.) administration. The proinflammatory cytokines, interleukin (IL)-1β, IL-6 and tumor necrosis factor-α, were detected in the mouse uterus by western blot analysis and cytokine enzyme-linked immunosorbent assay after HCl (25 mg/kg) administration i.c. followed by four LPS (50 mg/kg) treatments. Moreover, mice exhibited increased infiltration of neutrophils in the endometrium and epithelial layer. These results suggest that ic co-administration of HCl and LPS induces PID in mice. This new model may provide a consistent and reproducible PID model for future research.

Trichomonas vaginalis induces proinflammation in cervicovaginal mucosal epithelium. To investigate the signaling pathways in TNF-alpha production in cervical mucosal epithelium after T. vaginalis infection, the phosphorylation of PI3K/AKT and MAPK pathways were evaluated in T. vaginalis-infected SiHa cells in the presence and absence of specific inhibitors. T. vaginalis increased TNF-alpha production in SiHa cells, in a parasite burden-dependent and incubation time-dependent manner. In T. vaginalis-infected SiHa cells, AKT, ERK1/2, p38 MAPK, and JNK were phosphorylated from 1 hr after infection; however, the phosphorylation patterns were different from each other. After pretreatment with inhibitors of the PI3K/AKT and MAPK pathways, TNF-alpha production was significantly decreased compared to the control; however, TNF-alpha reduction patterns were different depending on the type of PI3K/MAPK inhibitors. TNF-alpha production was reduced in a dose-dependent manner by treatment with wortmannin and PD98059, whereas it was increased by SP600125. These data suggested that PI3K/AKT and MAPK signaling pathways are important in regulation of TNF-alpha production in cervical mucosal epithelial SiHa cells. However, activation patterns of each pathway were different from the types of PI3K/MAPK pathways.

PURPOSE: Phototherapy uses the changes caused by the athermal and atraumatic absorption of the photon's energy by the tissue for therapeutic effect. Phototherapy has been proven to be useful in various conditions, for example, in pain attenuation, wound healing and skin rejuvenation. The aim of this research was to evaluate the clinical efficacy of 830 nm LED phototherapy for burn patients. METHODS: We recruited 11 patients who visited this hospital between June and December 2012 with superficial 2nd degree burns to the face for comparative analysis. For phototherapy, we used infrared LED with wavelength of 830 nm. For comparative analysis, we covered one side of the face with sterile aluminum foil and fabric during the treatment. Photographs were taken at the time of each treatment and the time taken for epithelialization and the level of patient satisfaction were also investigated. RESULTS: All 11 patients were male and the mean age was 44.0+/-11.9 years (range of 28~63 years). The cause of the burns was flame burn for 7 patients, and electric sparks in 4 patients. The time taken to achieve epithelialization after the burns was 8.1+/-2.2 days (range 4~12 days) for the side that received phototherapy, while it was 9.1+/-2.9 days (range 4~14 days) for the side that was not treated with phototherapy. In terms of patient satisfaction, 3 patients were 'Very Satisfied', 6 patients were 'Satisfied', 2 patients replied 'Adequate' and none of the patients were 'Unsatisfied'. CONCLUSION: LED phototherapy of 830 nm wavelength can shorten the time taken for burn wound healing. It also was not associated with serious complications except for skin dryness, so it can be a useful treatment method for burns that produces satisfactory outcome for the patients.

PURPOSE: Marjolin's ulcer is a rare malignancy that occur in chronic wounds or scars. Marjolin's ulcers tend to infiltrate adjacent tissue more extensively than squamous cell carcinoma that occurs in normal skin, and it is prone to recurrence and metastases, leading to a poor prognosis. Hence, its accurate diagnosis and treatment is very important. The aim of this study was to investigate the diagnostic value and clinical efficacy of preoperative 18F-FDG-PET/CT. METHODS: The study population consisted of 27 patients who were suspected to have Marjolin's ulcer who visited this hospital between January 2009 and June 2012, and who had also received preoperative PET/CT. To confirm the diagnostic efficacy of preoperative PET/CT, the PET/CT findings of the primary lesion and the lymph node, as well as the post-operative histology results were compared to investigate the sensitivity, specificity, false-positive and false-negative rates. RESULTS: The sensitivity and the specificity for the primary lesion of the Marjolin's ulcer in the preoperative PET/CT were 93.3% and 100% respectively. The false-positive rate and the false-negative rate here were 0% and 6.7% respectively. The sensitivity and the specificity for the lymph node metastases of the Marjolin's ulcer in the preoperative PET/CT were 100% and 66.7% respectively. The false-positive rate and the false-negative rate here were 33.3% and 0% respectively. The histological results of Marjolin's ulcer showed that 14 patients had squamous cell carcinoma and 1 had sarcoma. CONCLUSION: Preoperative PET/CT used for the assessment of Marjolin's ulcer and its primary lesion showed a high level of sensitivity and specificity. It was also useful because it allowed the assessment of the primary lesion, lymph node metastases, and distant metastases with a single test. However, the specificity for lymph node metastases was relatively lower, and more research would be needed to improve this.

We report here on a case of genetically confirmed type Ia glycogen storage disease (GSD) that was diagnosed in the military hospital. A twenty-year old soldier was admitted to the hospital with abdominal fullness. He had a past medical history of hepatomegaly that was firstly recognized at six months after birth, and he had been followed-up at an outpatient clinic with the presumptive diagnosis of type III GSD. He also had a history of growth hormone therapy because of growth retardation. However, he arbitrarily refused medical observation from 14 years of age. On the physical examination, the height of the patient was 163.1 cm and significant hepatomegaly was observed. Significantly abnormal liver-associated paramters were observed on the laboratory findings and multiple hepatic adenomas were observed on the CT exam and MRI scan. To determine the proper treatment, we tried to confirm the exact type of GSD in the patient. By mutational analysis, we found the c.648G>T homozygote splicing mutation in the G6PC gene and the patient was confirmed as having the type Ia GSD.
