In connective tissue diseases, autoantibodies cause pulmonary interstitial inflammation and fibrosis, and patients require treatment with an immunosuppressive agent such as a steroid. Dermatomyositis is an incurable, uncommon form of connective tissue disease that occasionally causes diffuse pulmonary inflammation leading to acute severe respiratory failure. In such cases, the prognosis is very poor despite treatment with high-dose steroid. In the present case, a 46-year-old man was admitted to our hospital with dyspnea. He was diagnosed with dermatomyositis combined with cryptogenic organizing pneumonia (COP) with respiratory failure and underwent treatment with steroid and an immunosuppressive agent, but the COP was not improved. However, the respiratory failure did improve after treatment with intravenous immunoglobulin, which therefore can be considered a treatment option in cases where steroids and immunosuppressive agents are ineffective.

Background: Sarcopenia is commonly found in the elderly due to a decline in muscle mass.Many researchers have performed genome-wide association studies (GWAS) to find genetic risk factors of sarcopenia. Although many studies have discovered sarcopenia associated single nucleotide polymorphisms (SNPs), most of them are studies targeting Caucasians. The purpose of this study was to evaluate genetic correlation according to muscle mass in middle aged Koreans using data of the Korean Genome and Epidemiology Study (KOGES), a large population-based genomic cohort study. Methods: Baseline participants were 10,030 subjects aged 40 to 69 years who were from Ansan or Anseong in Gyeonggi-do, South Korea. Among them, 9,351 subjects with laboratory data available were included in this study. To identify sarcopenia associated variants, those in the top 30% and bottom 30% of muscle mass index (MMI) were compared. A total of 7,452 people with an MMI of 30-70% were excluded. A total of 1,004 people were also excluded due to missing data. Finally, 895 people were selected for this study. The Korea Biobank Array generated 500,568 SNPs for this dataset. Results: When subjects were divided into top 30% and bottom 30% of MMI, the top 30% had 169 men and 308 women and the bottom 30% had 220 men and 198 women. In men, age, body mass index (BMI), waist and hip were significantly (P < 0.005) different between top 30% and bottom 30% MMI groups. In women, age, BMI, waist, hip, and hypertension history were significantly different between the two MMI groups. There were 13 significant SNPs in men and 14 significant SNPs in women. Genes associated with variants in men based on the single-nucleotide polymorphism database (dbSNP) were LRP1B containing rs11679458 and RGS6 containing rs11848300. A gene associated with variants in women was Pi4K2A, which contained rs1189312 as a variant. In addition, rs11189312 was associated with expression quantitative trait loci (eQTL) of ZFYVE27 in skeletal muscles and other SNPs of ZFYVE27 (rs10882883, rs17108378, rs35077384) known to be associated with spastic paraplegia. The eQTL analysis revealed that rs11189312 was a variant associated with SNPs of ZFYVE27. Conclusions In the demographic study, significant results were found in BMI, waist, hip, history of hyperlipidemia, and sedentary life status in male group, and significant results were found in BMI, waist, hip, and hypertension history in female group. Variant rs11189312 was found to be a novel variant affecting ZFYVE27 expressed in skeletal muscles, suggesting that rs11189312 might be related to sarcopenia as a novel discovery of this study. Further study is needed to determine the association between sarcopenia and ZFYVE27 known to be associated with spastic paraplegia.

Neurogenic pulmonary edema (NPE) leading to cardiopulmonary dysfunction is a potentially life-threatening complication in patients with central nervous system lesions. This case report describes a 28-yr woman with life-threatening fulminant NPE, which was refractory to conventional respiratory treatment, following the rupture of an aneurysm. She was treated successfully with extracorporeal membrane oxygenation (ECMO), although ECMO therapy is generally contraindicated in neurological injuries such as brain trauma and diseases that are likely to require surgical intervention. The success of this treatment suggests that ECMO therapy should not be withheld from patients with life-threatening fulminant NPE after subarachnoid hemorrhage.

PURPOSE: Heat shock factor 1 (HSF1) is a key regulator of the heat shock response and plays an important role in various cancers. However, the role of HSF1 in gastric cancer is still unknown. The present study evaluated the function of HSF1 and related mechanisms in gastric cancer. MATERIALS AND METHODS: The expression levels of HSF1 in normal and gastric cancer tissues were compared using cDNA microarray data from the NCBI Gene Expression Omnibus (GEO) dataset. The proliferation of gastric cancer cells was analyzed using the WST assay. Transwell migration and invasion assays were used to evaluate the migration and invasion abilities of gastric cancer cells. Protein levels of HSF1 were analyzed using immunohistochemical staining of tissue microarrays from patients with gastric cancer. RESULTS: HSF1 expression was significantly higher in gastric cancer tissue than in normal tissue. Knockdown of HSF1 reduced the proliferation, migration, and invasion of gastric cancer cells, while HSF1 overexpression promoted proliferation, migration, and invasion of gastric cancer cells. Furthermore, HSF1 promoted the proliferation of gastric cancer cells in vivo. In Kaplan-Meier analysis, high levels of HSF1 were associated with poor prognosis for patients with gastric cancer (p=0.028). CONCLUSION: HSF1 may be closely associated with the proliferation and motility of gastric cancer cells and poor prognosis of patients with gastric cancer. Accordingly, HSF1 could serve as a prognostic marker for gastric cancer.

OBJECTIVES: The purpose of this study was to investigate the distinctive features of bodily panic symptoms and the predisposing conditions in Korean patients with panic disorder. METHODS: This was a retrospective chart review study and the data were collected from twelve university-affiliated hospitals in Korea. The patients selected met the diagnostic criteria for panic disorder, were older than 20 years of age, and had initially visited a psychiatry department. The assessments included the chief complaints related to bodily panic symptoms, recent stressors, recent history of alcohol and sleep problems, and time to visit an outpatient clinic. RESULTS: A total of 814 participants were included in the study. The most commonly experienced symptoms were cardiovascular and respiratory symptoms, which were observed in 63.9% and 55.4% of participants, respectively. Just before the onset of a panic attack, 25.6% of participants experienced sleep-related problems. Episodic binge drinking was also frequently observed (13.2%) and was more prevalent in men than in women (22.6% vs. 4.9%, p<0.001). About 75% of participants experienced stressful life events just before panic onset. Work-related issues were more prevalent in men than in women (22.0% vs. 13.4%, p=0.001). Family-related issues (4.8% vs. 14.1%, p<0.001) and conflict with a spouse or partner (4.0% vs.11.7%, p<0.001) were more prominent in women than in men. CONCLUSION Our results suggest that cardiovascular symptoms are the most common bodily panic symptoms in Korean patients. Our results suggest that a substantial portion of the Korean patients experienced stressful life events, sleep problems, and/or episodic binge drinking just before the onset of panic disorder.

From January 1, 2016 to December 31, 2016, a total of 1147 postmortem inspection cases in Area 8, Seoul Metropolitan Police Agency (Gangseo, Yangcheon, and Guro police stations) were statistically analyzed. Autopsies were performed in 205 cases (17.9%), and the autopsy rates were 17.6% (75/426 cases) in the Gangseo police station, 9.5% (34/357 cases) in the Yangcheon police station, and 24.3% (82/337 cases) in the Guro police station. For 288 cases with an unknown cause of death, the autopsy rates were 70.0% (60/87 cases) in the Gangseo police station, 28.6% (26/91 cases) in the Yangcheon police station, and 63.1% (65/103 cases) in the Guro police station. For 65 cases due to fall from height, the autopsy rate was 7.7% (n=5). Of the 187 cases due to hanging, 155 cases were classified as suicide at the scene with a 4.5% (n=7) autopsy rate and 32 cases were classified as an undetermined manner of death at the scene with a 15.6% (n=5) autopsy rate. The distribution of the “manner of death” was natural death, 45% (n=516); unnatural death, 29.9% (n=343); and other and undetermined, 25.1% (n=288). Proportions of dispatch times were 50.9% (584 cases) during work hours (09:00–18:00), 13.8% (n=158) during evening hours (18:00–21:00), 13.4% (n=154) at night (21:00–00:00), 11% (n=126) at dawn (00:00–06:00), and 10.9% (n=125) during morning hours (06:00–09:00). The male-to-female ratio was 1.86:1 (746:401). These statistics are valuable for the evaluation of postmortem inspections by experts.
