ABSTRACT
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. Hyperuricemia was defined as a serum uric acid concentration of > or =7.0 mg/dL. Logistic regression analyses were performed. In the full model, analysis was adjusted for covariates including age, body mass index, lifestyle factors, and comorbidities. The odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated for all models. RESULTS: The participants included 276 daytime workers and 753 shift workers. Among daytime workers, 72 (26.1%) individuals had hyperuricemia, as did 282 (37.5%) individuals among shift workers (p <0.001). There was a statistically significant association between shift work and hyperuricemia. In the unadjusted model, the OR of shift work was 1.70 (95% CI 1.25-2.31) for hyperuricemia. In the full model, the OR of shift work was also statistically significant after adjustment for covariates (OR 1.41, 95% CI 1.02-1.96). CONCLUSIONS: Among male steel workers, a significant association between shift work and hyperuricemia was observed.

The percutaneous placement of a totally implantable vascular access port via the subclavian vein is commonly used in patients with a need for multiple intravenous infusions such as administration of chemotherapy. Unfortunately, the use of central venous ports have been associated with adverse events that are hazardous to patients. Here we report the case of a 5-year-old child who died of catastrophic hemothorax after several attempts at insertion of an implantable subclavian venous access device and removal of an infected port. Massive hemothorax occurred on the side contralateral to unsuccessful attempts at insertion of a new port and ipsilateral to the removal of an infected port. We could not confirm the cause of death and hemothorax without autopsy, but we discuss several possible causes of massive hemothorax.

Dubowitz syndrome is a rare autosomal recessive disorder that leads to growth retardation (intrauterine, postnatal), mental retardation, a peculiar face, microcephaly, behavioral problems and eczema. The peculiar face of individuals with Dubowitz syndrome includes sparse hair and eyebrows, low-set ears, blepharophimosis, bilateral ptosis, a flat nasal bridge with a broad nasal root and micrognathia. Airway management of such individuals might be difficult due to craniofacial anomalies, such as micrognathia, cleft palate, tooth problems and craniocervical anomalies. In addition, anesthetic management may be complicated by other systemic illnesses. We report the uneventful anesthetic management of a 16-year-old girl with Dubowitz syndrome who underwent a total abdominal hysterectomy after a pelvic examination under general anesthesia. We report this case of Dubowitz syndrome with a review of the relevant literature.

Transurethral resection is frequently performed urologic operation for benign prostate hypertrophy, prostate cancer, bladder cancer. During transurethral resection, urologists generally use room temperature irrigation fluid, and there is a chance that patients will run into hypothermia. Hypothermia may lead to arrhythmia, reduction of cardiac output, coagulation disorder, metabolic acidosis, and further serious life threatening complications. This case describes a sudden drop in core temperature due to bladder perforation and intraperitoneal leakage of irrigation fluid during transurethral resection of bladder tumor.

The index on myocardial contractility of pure mitral regurgitation(MR) after mitral valve replacement is believed to be useful in determining proper operation time before irreversible myocardial damage by volume overload. Thus the authors examined pre and post-operative echocardiographic results of 20 cases of pure MR patients who had been admitted to Pusan National University hospital and compared the usefulness of each index. Pre and post-operative echocardiographic results were as follows respectively ; 1) Left ventricular internal dimension in diastole(LVIDd) were 6.49+/-0.19cm and 5.51+/-0.17cm. 2) Left ventricular internal dimension in systole(LVIDs) were 4.26+/-0.12 and 3.79+/-0.18cm. 3) Ejection fraction were 71.28+/-1.57% and 59.24+/-3.05%. 4) Fractional shortening(FS) were 34.09+/-1.18% and 27.21+/-1.84%. 5) Mean Vcf were 1.53+/-0.08cm/sec and 1.18+/-0.09cm/sec. 6) Left ventricular end-diastolic volume index(EDVI) were 196.35+/-18.33cc/m2 and 98.46+/-9.96cc/m2. 7) Left ventricular end-systolic volume index(ESVI) were 55.28+/-5.12cc/m2 and 41.88+/-6.07cc/m2. 8) Left ventricular end-systolic wall stress/ESVI(ESS/ESVI) were 2.3+/-0.21 and 3.91+/-0.83. ESS/ESVI showed significantly(p6cm, LVIDs>4cm, and ESS/ESVI<2, the prognosis was poor due to myocardial damage by mitral regurgitation.
