BACKGROUND: Infectious conditions may increase the risk of venous thromboembolism. The purpose of this study was to evaluate the risk factor for combined infectious disease and its influence on mortality in patients with pulmonary embolism (PE).METHODS: Patients with PE diagnosed based on spiral computed tomography findings of the chest were retrospectively analyzed. They were classified into two groups: patients who developed PE in the setting of infectious disease or those with PE without infection based on review of their medical charts.RESULTS: Of 258 patients with PE, 67 (25.9%) were considered as having PE combined with infectious disease. The sites of infections were the respiratory tract in 52 patients (77.6%), genitourinary tract in three patients (4.5%), and hepatobiliary tract in three patients (4.5%). Underlying lung disease (odds ratio [OR], 3.69; 95% confidence interval [CI], 1.926–7.081; p<0.001), bed-ridden state (OR, 2.84; 95% CI, 1.390–5.811; p=0.004), and malignant disease (OR, 1.867; 95% CI, 1.017–3.425; p=0.044) were associated with combined infectious disease in patients with PE. In-hospital mortality was higher in patients with PE combined with infectious disease than in those with PE without infection (24.6% vs. 11.0%, p=0.006). In the multivariate analysis, combined infectious disease (OR, 4.189; 95% CI, 1.692–10.372; p=0.002) were associated with non-survivors in patients with PE.CONCLUSION: A substantial portion of patients with PE has concomitant infectious disease and it may contribute a mortality in patients with PE.

OBJECTIVE: This study assessed whether characteristics of ruptured hepatocellular carcinoma (HCC) at presentation to the emergency department (ED) affect patient outcomes, and evaluated factors prognostic of HCC, particularly treatment modalities. METHODS: This retrospective study between 2008 and 2017 evaluated patients presenting to an ED with ruptured HCC. Parameters associated with 30- and 90-day mortality were investigated, and clinical characteristics and treatments were analyzed. RESULTS: In total, 121 patients presented to the ED with ruptured HCC. Of these, 29 died within 30 days. Multivariate logistic regression analysis showed that platelet count (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.976–0.995) and prothrombin time (OR, 16.20; 95% CI, 1.91–137.23) were associated with a 30-day mortality rate, whereas presence or absence of acute abdominal pain and shock at presentation to the ED was not significant. Patients who underwent embolization had a lower 30-day mortality rate than those treated conservatively (OR, 0.04; 95% CI, 0.001-0.20). Sixtyone patients died within 90 days after presentation to the ED. Serum albumin concentration (OR, 0.25; 95% CI, 0.09–0.71) was associated with 90-day mortality. Moreover, patients who underwent embolization (OR, 0.19; 95% CI, 0.06–0.60) and emergency hepatectomy (OR 0.09; 95% CI, 0.01–0.99) had lower 90-day mortality rates as compared to patients treated conservatively. CONCLUSION Presence of acute abdominal pain at presentation to the ED does not affect patient outcomes. Early aggressive treatments, such as embolization or emergency hepatectomy, were observed to improve outcomes in patients with ruptured HCC.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) may cause changes in the shape of the thoracic cage by increasing lung volume and hyperinflation. This study investigated changes in thoracic cage dimensions and related factors in patients with COPD. METHODS: We enrolled 85 patients with COPD (76 males, 9 females; mean age, 70.6±7.1 years) and 30 normal controls. Thoracic cage dimensions were measured using chest computed tomography at levels 3, 6, and 9 of the thoracic spine. We measured the maximal transverse diameter, mid-sagittal anteroposterior (AP) diameter, and maximal AP diameter of the right and left hemithorax. RESULTS: The average AP diameter was significantly greater in patients with COPD compared with normal controls (13.1±2.8 cm vs. 12.2±1.13 cm, respectively; p=0.001). The ratio of AP/transverse diameter of the thoracic cage was also significantly greater in patients with COPD compared with normal controls (0.66±0.061 vs. 0.61±0.86; p=0.002). In COPD patients, the AP diameter of the thoracic cage was positively correlated with body mass index (BMI) and 6-minute walk test distance (r=0.395, p<0.001 and r=0.238, p=0.028) and negatively correlated with increasing age (r=−0.231, p=0.034). Multiple regression analysis revealed independent correlation only between BMI and increased ratio of AP/transverse diameter of the thoracic cage (p<0.001). CONCLUSION: Patients with COPD exhibited an increased AP diameter of the thoracic cage compared with normal controls. BMI was associated with increased AP diameter in these patients.

BACKGROUND: The aim of this study was to examine the influence of body mass index (BMI) on the development of acute kidney injury (AKI) in critically ill patients in intensive care unit (ICU). METHODS: Data of patients admitted to medical ICU from December 2011 to May 2014 were retrospectively analyzed. Patients were classified into three groups according to their BMI: underweight ( < 18.5 kg/m2), normal (18.5–24.9 kg/m2), and overweight (≥25 kg/m2). The incidence of AKI was compared among these groups and factors associated with the development of AKI were analyzed. AKI was defined according to the Risk, Injury, Failure, Loss of kidney function, and End-stage (RIFLE) kidney disease criteria. RESULTS: A total of 468 patients were analyzed. Their mean BMI was 21.5±3.9 kg/m2, including 102 (21.8%) underweight, 286 (61.1%) normal-weight, and 80 (17.1%) overweight patients. Overall, AKI occurred in 82 (17.5%) patients. The overweight group had significantly (p < 0.001) higher incidence of AKI (36.3%) than the underweight (9.8%) or normal group (15.0%). In addition, BMI was significantly higher in patients with AKI than that in those without AKI (23.4±4.2 vs. 21.1±3.7, p < 0.001). Multivariate analysis showed that BMI was significantly associated with the development of AKI (odds ratio, 1.893; 95% confidence interval, 1.224–2.927). CONCLUSION: BMI may be associated with the development of AKI in critically ill patients.

OBJECTIVE: To evaluate the efficacy of temozolomide (TMZ) chemotherapy for recurrent anaplastic oligodendroglioma (AO) and anaplastic oligoastrocytoma (AOA). METHODS: A multi-center retrospective trial enrolled seventy-two patients with histologically proven AO/AOA who underwent TMZ chemotherapy for their recurrent tumors from 2006 to 2010. TMZ was administered orally (150 to 200 mg/m2/day) for 5 days per 28 days until unacceptable toxicity occurred or tumor progression was observed. RESULTS: TMZ chemotherapy cycles administered was median 5.3 (range, 1-41). The objective response rate was 24% including 8 cases (11%) of complete response and another 23 patients (32%) were remained as stable disease. Severe side effects (> or =grade 3) occurred only in 9 patients (13%). Progression-free survival (PFS) of all patients was a median 8.0 months (95% confidence interval, 6.0-10.0). The time to recurrence of a year or after was a favorable prognostic factor for PFS (p<0.05). Overall survival (OS) was apparently differed by the patient's histology, as AOA patients survived a median OS of 18.0 months while AO patients did not reach median OS at median follow-up of 11.5 months (range 2.7-65 months). Good performance status of Eastern Cooperative Oncology Group 0 and 1 showed prolonged OS (p<0.01). CONCLUSION: For recurrent AO/AOA after surgery followed by radiation therapy, TMZ could be recommended as a salvage therapy at the estimated efficacy equal to procarbazine, lomustine, and vincristine (PCV) chemotherapy at first relapse. For patients previously treated with PCV, TMZ is a favorable therapeutic option as 2nd line salvage chemotherapy with an acceptable toxicity rate.

Stress-induced cardiomyopathy, also known as Takotsubo cardiomyopathy, is caused by emotional or physical stressors and mimics acute myocardial infarction. Stress-induced cardiomyopathy is characterized by acute, reversible left ventricular apical ballooning without significant coronary artery stenosis. New variants of stress-induced cardiomyo pathy with localized wall motion abnormalities or an inverted pattern with a hyperdynamic apex have been reported. We present a rare case of a sudden cardiac arrest due to atypical stress-induced cardiomyopathy (mucosal packing and the injection of epinephrine) in an elderly male patient during elective endoscopic sinus surgery with septoplasty under local anesthesia. In this case, only the basal and midportions of the left ventricle were affected, whereas the apex was completely spared. The patient rapidly and completely recovered without sequelae.

We report here on a rare case of adrenal paragonimiasis that presented with an adrenal incidentaloma. A 52-year-old male presented with fatigue and weight loss. The laboratory findings revealed eosinophilia (8.5%) and an increased eosinophil count (910/microL). The computed tomography scan showed 6.5 x 5 cm sized multilocular cystic mass in the right adrenal gland, which was non-functioning, and cystic lesions with variable sizes were also noted in the abdominal cavity. On the surgical field, whitish patches were spread out in the peritoneum, the omentum, the dome of the liver and the diaphragm. The right adrenal gland was replaced by a cystic mass filled with mucopurulent creamy materials. The pathologic findings revealed numerous eggs of Paragonimus spp. Also, the ELISA was positive for IgG paragonimus antibody. The adrenal gland can become infected by various microbial pathogens, including parasites, although it is relatively uncommon. However, in the case of a cystic adrenal mass with accompanying eosinophilia in an endemic area, clinicians should consider the possibility of parasitic infection.

OBJECTIVES: This study aimed to assess the relationship between musculoskeletal symptoms and non-fatal injuries in construction workers. METHODS: This was a cross-sectional study involving 1,836 male construction workers in petrochemical plants in Korea. For this study, a structured self-reported questionnaire(KOSHA CODE H-30-2003) was used. Musculoskeletal symptoms were defined as symptoms that affect the operation of the musculoskeletal system, for longer than one week or a frequency of more than once per month. To evaluate the association between musculoskeletal symptoms and non-fatal occupatioanl injuries, multiple logistic-regressions were used after adjusting for age, exercise, smoking status, alcohol consumption, work time, work duration, and income. RESULTS: A total of 140 workers were involved in non-fatal injuries cases, representing 7.6% prevalence. After adjusting for confounding variables, the logistic regression analyses indicated the group with musculoskeletal symptoms(OR 1.73 95% CI:1.21~2.47) and intensity criteria of musculoskeletal symptoms as related to 'moderate' criteria(OR 1.82 95% CI:1.18~2.81) or 'severe' criteria(OR 2.57 95% CI:1.43~4.63). This identified group was more likely to experience non-fatal occupational injuries. However, a 'mild' criteria(OR 1.00 95% CI:0.51~1.99) was not associated with non-fatal occupational injuries. CONCLUSIONS: The results indicated a possible association between musculoskeletal symptoms and non-fatal injuries. Hence, strengthening of laws and regulations, effective ergonomic programs and training is necessary to prevent musculoskeletal symptoms.

Species of Phoma and its allies were isolated during a survey on the diversity of endophytic fungi associated with pine trees in Korea. Based on the phylogenetic analyses of internal transcribed spacer and beta-tubulin gene sequences, two Phoma-like species from the needles of Pinus koraiensis were identified as Peyronellaea calorpreferens and P. glomerata. They were also morphologically identified based on the previous descriptions. Here, we report P. calorpreferens and P. glomerata being present in Korea as endophytic fungi in Pinus koraiensis.
