Acute respiratory symptoms and evacuation-related behavior after exposure to chlorine gas leakage.

Background: A study was performed on the accidental chlorine gas leakage that occurred in a factory of printed circuit boards manufactured without chlorine. Health examination was performed for all 52 workers suspected of exposure to chlorine gas, and their evacuation-related behaviors were observed in addition to analyzing the factors that affected the duration of their acute respiratory symptoms.

Methods: Behavioral characteristics during the incidence of the accidental chlorine gas leakage, the estimated time of exposure, and the duration of subjective acute respiratory symptoms were investigated.

Overlap syndrome with Sjögren's syndrome and systemic sclerosis in a steel rolling mill worker: a case report.

Background: There are few reports about work-related factors associated with Sjögren's syndrome. We report a case of overlap syndrome with Sjögren's syndrome and systemic sclerosis.

Case Presentation: A 54-year-old man was admitted due to dyspnea on exertion.

Blood Cadmium Is Associated with Osteoporosis in Obese Males but Not in Non-Obese Males: The Korea National Health and Nutrition Examination Survey 2008-2011.

Osteoporosis in males is becoming an important health concern in an aging society. The aim of this study was to investigate the associations between cadmium exposure and osteoporosis by considering the effect of obesity in aged males using a representative sample of the Korean population. Using the fourth and fifth Korea National Health and Nutrition Examination Survey data, 1098 males over 50 years of age were analyzed.

The association between shift work and hyperuricemia in steelmaking male workers.

Objectives: The aim of this study was to examine the association between shift work and hyperuricemia among steel company workers.

Methods: We examined 1,029 male workers at a Korean steel company between June 6 and June 28, 2013. We conducted anthropometric measurements, questionnaire surveys, and blood tests.

The relevance of hyperuricemia and metabolic syndrome and the effect of blood lead level on uric Acid concentration in steelmaking workers.

Objectives: Uric acid concentration is known to increase the prevalence of metabolic syndrome by affecting its components, resulting in increased risk of cerebrovascular and cardiovascular diseases, and long-term lead exposure is known to affect this serum uric acid level. In this study, we aimed to examine the association between the causes of hyperuricemia and metabolic syndrome, and to determine whether an increased blood lead level affects hyperuricemia.

Method: Anthropometric measurements, surveys, and blood tests were conducted between May and June 2012 in 759 men working in the steelmaking process at a domestic steel company.

Implication of high-body-fat percentage on cardiometabolic risk in middle-aged, healthy, normal-weight adults.

Objective: This study investigated the number of Korean adults who had a normal body mass index (BMI) but high body-fat percentage (BF%) and determined their increased risk factors for cardiovascular diseases, including high blood pressure, hyperglycemia, and dyslipidemia.

Design And Methods: This cross-sectional study was based on 12,386 subjects (6,534 men and 5,852 women), with a normal BMI, between 30 and 49 years of age. Subjects were categorized into two groups by BF% (normal BF% group, BF% <25 for men, and BF% <30 for women; high BF(%) group, BF% ≥25 for men, and BF% ≥30 for women).

A case-crossover study of transient risk factors for occupational traumatic hand injuries in Incheon, Korea.

Objectives: A case-crossover study was conducted to identify transient risk factors for occupational acute hand injuries.

Methods: In total, 98 subjects were recruited from a hospital specializing in occupational accidents and trauma. Patients who had injured fingers, hands or wrists during work were interviewed within 30 days after their accidents.

Symptom prevalence of musculoskeletal disorders and the effects of prior acute injury among aging male steelworkers.

Objectives: The prevalence of musculoskeletal symptoms and related factors were investigated by a structured questionnaire among male steel workers at a large steel company in Korea including a number of aged employees and workers with prior acute injuries.

Methods: Of an eligible 2,093 workers, 1,836 responded to the survey. Among 39 job groups, 8 major job groups (1,068 subjects) were selected to evaluate the potential risk factors of musculoskeletal symptoms.

Mismatch between PFNa and medullary canal causing difficulty in nailing of the pertrochanteric fractures.

The proximal femoral nail (PFN) and the proximal femoral nail anti-rotation (PFNA) have been successfully used in the management of osteoporotic pertrochanteric fractures. Although many studies have described the geometrical mismatch between the antecurvation of the femur and the contemporary intramedullay nails, technical difficulties related to the mismatch between the femoral bowing and the PFN/PFNA at the time of nailing have rarely been discussed in the literature. We have experienced a technical difficulty related to the mismatch between the medullary canal and the PFN/PFNA.

Pelvic osteolysis relationship to radiographs and polyethylene wear.

The relationship of radiographic pelvic osteolysis to computed tomographic (CT) volume and polyethylene wear remains controversial. We evaluated the sensitivity and specificity of radiographs in detecting osteolysis considering CT scan as the true value, in 118 hips with cementless cups. Correlation between osteolysis volume in CT, area of osteolysis in radiograph, and linear wear of polyethylene was assessed.
