BACKGROUND: This study was conducted to identify the sleep status of daytime workers who do not work in shifts. This study analyzed factors affecting sleep duration and sleep quality. METHODS: This study was conducted on 1171 daytime workers at a manufacturing workshop. We used a self-administered questionnaire to investigate demographic variables, work type, working period, musculoskeletal symptoms and the Pittsburgh Sleep Quality Index to assess sleep. Regular health checkup was conducted for the worker’s clinical examination. RESULTS: The mean sleep duration was 6.36 h and the mean score on the Pittsburgh Sleep Quality Index was 4.46. Work type and obesity were related to sleep duration. Age, obesity and musculoskeletal pain were significantly related to sleep quality. The prevalence ratio of researcher group for short sleep duration was 1.27 (95% confidence interval: 1.02–1.58). The prevalence ratio of those aged 50 years and over was 0.47 (0.25–0.91) and of those in their 40s was 0.56 (0.35–0.91) for poor sleep quality compared to those in their 20s. The prevalence ratio of the obesity group for poor sleep quality was 1.53 (1.10–2.12). The prevalence ratio of musculoskeletal pain group for poor sleep quality was 1.92 (1.29–2.84). CONCLUSIONS: Age, obesity and musculoskeletal pain were factors affecting the poor quality on sleep of daytime workers. In addition, work type related to short sleep duration.

BACKGROUND: The aspartate transaminase (AST)/alanine transferase (ALT) ratio increases with alcohol consumption. This study investigated AST/ALT ratio according to alcohol drinking and predictive power of AST/ALT ratio for heavy drinking in Korean men. METHODS: In 2015, 830 men with no history of disease or medication affecting liver function values were selected. Using 14 g of alcohol as the standard glass, odd ratios (ORs) of AST/ALT ratio over 1 among the drinking group were compared with the non-drinking group by multiple logistic analyses. Screening of heavy drinkers was conducted according to both NIAAA and Korean guidelines. Using AST/ALT ratio >1, sensitivity, specificity, positive predictive values, negative predictive values, positive likelihood ratios, negative likelihood ratios and odds ratios were investigated. RESULTS: After correcting for age, body mass index, exercising, and smoking history, ORs (95% confidence interval) of AST/ALT >1 were 1.607 (1.048-2.464) in <8 glasses group, 2.172 (1.160-4.065) in the 14 glasses group, and 3.670 (2.218-6.053) in the >14 glasses group. When AST/ALT >1 in the drinking group, sensitivity, specificity, positive predictive values, negative predictive values, likelihood ratios (LR)+, LR- and OR according to NIAAA guidelines, were 57.2%, 52.7%, 23.2%, 76.8%, 1.21 (1.04-1.41), 0.81 (0.67-0.98), and 1.49 (1.05-2.01), respectively. By Korean guidelines, these values were 55.2%, 55.3%, 33.7%, 66.3%, 1.24 (1.03-1.36), 0.84 (0.72-0.98), and 1.40 (1.04-1.89), respectively. CONCLUSIONS: Healthy male adults showed a positive correlation between risk of AST/ALT >1 and drinking amount compared to the non-drinking group. Use of the AST/ALT >1 in combination with other blood markers to predict excessive drinking is advisable.

Acute pelvic pain is one of the most common complaints of woman presenting in the emergency department. When gynecologic disorders are suspected, ultrasonography (US) is the modality of choice, enabling rapid diagnosis and decision making with regard to appropriate management. Frequent gynecologic etiologies include a large or enlarging simple ovarian cyst, hemorrhagic ovarian cyst or rupture of an ovarian cyst, acute pelvic inflammatory disease, and ovarian torsion. Endometriosis, uterine leiomyoma, and peritoneal inclusion cyst can also present as acute pelvic pain. Gynecologic disorders that cause acute pelvic pain frequently show characteristic ultrasonographic findings that enable specific diagnosis. In this review, the authors review ultrasonographic findings of gynecologic causes of acute pelvic pain.

Although arteriovenous malformations (AVM) occur frequently in digestive organs, pancreatic AVM is rare. The clinical symptoms of pancreatic AVM are variable and include gastrointestinal bleeding, abdominal pain, jaundice, portal hypertension, pancreatitis, and duodenal ulcer. However, choledochoduodenal or pancreaticoduodenal fistulas complicated with ascending infection and pancreatitis is extremely rare. Herein, we report a case of pancreaticoduodenal fistula associated with a pancreatic AVM that induced recurrent anemia and ascending infection.

Axillary disorders originate from an axillary lymph node, subcutaneous fat layer, accessory breast, nerve, vessel and muscle. The most common causes of a palpable axillary mass are a lymph node pathology containing a benign axillary lymphadenopathy, and malignant lymph nodes such as a metastatic lymphadenopathy from breast cancer and a malignant lymphoma. For the detection of masses in the axilla, mammography and sonography are the imaging modalities of choice. We present a spectrum of various axillary masses with correlative radiological imaging and pathological findings in this pictorial essay. Knowledge of the radiological findings of various axillary disorders is useful for a differential diagnosis and for preventing unnecessary invasive procedures.

BACKGROUND AND OBJECTIVES: Direct stenting (DS) has been shown to be safe and feasible, with demonstrable reductions in cost, procedural time and radiation exposure, and may also result in less vessel injury. The aim of this study was to compare the immediate and six month clinical and angiographic outcomes of direct stent (DS) with stent implantation implantation following balloon predilatation (conventional stenting, CS). SUBJECTS AND METHODS: Between July 2001 and June 2004, 266 patients (293 lesions) with angina pectoris were included in this study. Patients having lesion characteristics with excessive calcification, left main lesion, chronic total occlusion, severe proximal tortuosity and a bifurcated lesion were excluded. Follow up angiography was performed about six months after the initial procedure. RESULTS: Direct (73 lesions) and conventional stenting (220 lesions) were performed respectively. In the DS group, the minimal luminal diameter was larger (0.36+/-0.18 vs. 0.31+/-0.19 mm, p=0.036) and diameter stenosis lower than in the CS group (89.1+/-5.1 vs. 90.6+/-3.9%, p=0.026). However, no difference was found in the reference vessel diameter between the two groups. From the immediate angiographic results, the CS group showed a longer stent length than the DS group (18.84+/-5.61 vs. 16.16+/-3.67 mm, p=0.000), but the DS group had a higher balloon inflation pressure than the CS group (12.25+/-1.71 vs. 11.35+/-1.72 atm, p=0.000). However, no difference was found in the post-stent minimal luminal diameter, acute gain and angiographic success rates. Follow up angiography was performed in 68.6% (201/293) of lesions. The angiographic restenosis rate was similar between the two groups (DS, 19.6 vs. CS, 19.3%, p=0.966), as were the other angiographic findings. The rates of in-hospital and 6 month follow up major adverse cardiovascular events (MACE) were similar between the two groups. CONCLUSION: Direct stenting showed similar rates of angiographic restenosis as well as inhospital and 6 months MACE (death, myocardial infarction, target lesion revascularization, cerebrovascular accident) compared with conventional stenting.

The present study was done to validate the two-site Semmes-Weinstein (SW) monofilament test in identifying patients at risk of lower-extremity complications in clinical setting. The SW monofilament test and nerve conduction study were conducted on type 2 diabetic patients (n=37) at Pusan National University Hospital in Korea. As the duration of diabetes mellitus was longer, neuropathy identified by nerve conduction study and complications of diabetes were more severe (p<0.01). The number of sites unable to perceive SW monofilament (p<0.001) was larger in patients with lower-extremity neuropathy symptoms than those without symptoms. Sensitivity and specificity at two sites (the third and fifth metatarsal head sites) were 93% and 100%, respectively. In conclusion, the two-site SW monofilament test was a sensitive, specific, simple, and inexpensive screening tool for identifying diabetic peripheral neuropathy in clinical setting.

Sparganosis is not a common disease, and its rarity makes it difficult to distinguish from other disease. Most cases of sparganosis are found in subcutaneous or adipose tissue of the abdominal, thoracic wall, and inguinal regions, but are rarely found in the breast. We experienced a case of sparganosis in the breast of a 65-year-old female by using an excisional biopsy. A sparganum should be considered in the differential diagnosis of benign breast disease.

A 57-year-old woman developed an inflammatory carcinoma in her left breast next to the spot of a silicone injection that had been used for augmentation some 20 years previously. She underwent a modified radical mastectomy with an axillary lymph node dissection. There have been relatively few cases reported in the literature that have noted breast cancer associated with silicone injections. During physical examinations, such breasts are frequently firm, tender, painful, and inflamed. Far more important, in silicone-injected breasts, carcinomas become more difficult to detect by physical examination, mam mography, and other known methods. Although no causal relationship between silicone and breast carci nomas is implied, a heightened awareness of the possible coexistence of silicone mastopathy and a breast carcinoma is necessary.
