PURPOSE: This study was conducted to assess the effects of lights-out at nighttime on body weight, physiological variables, and behavioral status in premature infants and to provide basic data for applying lights-out at night time in premature infants. METHODS: Premature infants of over 32 weeks' corrected age were included in this study (January 2015-June 2015), and were allocated to two groups according to the lights-out at night for 5 hours: study group and control group. Lights-out was applied to the study group from midnight for five hours in a quiet environment. RESULTS: Fifty-two infants were included in the study: 26 in the study group and 26 in the control group. Growth rates of body weight, height, and head circumference were higher in the study group compared to the control group, but there were no statistical differences. In the physiological variables, heart rate decreased by 6.9 beats per minute in the study group, but it increased by 2.7 beats per minute in the control group (P<0.0001) during applied 5 hours at night. Anderson Behavioral State Score decreased in the study group compared to the control group (P=0.042). CONCLUSION: Lights-out at night decreased the heart rate and made the behavioral status more stable. To understand the effects of lights-out on long-term growth and development of premature infants at the highest risk of delayed growth and development, further studies with a larger number of premature infants are needed.

Dermatofibrosarcoma protuberans is a dermal spindle cell neoplasm of intermediate malignancy, and is characterized by a high local recurrence rate after surgical excision due to its aggressive, finger-like outgrowth pattern. Mohs micrographic surgery, which ensures complete excision of the tumor and minimizes normal tissue loss, is accepted as the treatment of choice for dermatofibrosarcoma protuberans. However, the use of frozen sections for margin control in dermatofibrosarcoma protuberans is controversial because it could be difficult to differentiate minimal residual tumor from normal skin on the frozen sections, and is more challenging in recurrent disease because of the scar tissue. We report a case of a recurrent dermatofibrosarcoma protuberans in which the tumor was excised using the Mohs surgical technique and margin control was achieved with horizontally-cut paraffin-embedded permanent sections, named as rush permanent sections.

Background: Ultrasound is commonly used for evaluating rotator cuff tears. However, little training in ultrasound imaging is provided during orthopedic residents’ training period. Therefore, we performed this study to determine how many ultrasound scans are required for orthopedic residents to be competent and self-confident in the diagnosis of supraspinatus tendon tears and to investigate whether senior residents outperformed junior residents. Methods: We studied two third-year residents who had no previous experience of shoulder ultrasound and evaluated their ability to detect rotator cuff pathologies. Their learning curves were plotted using a cumulative summation analysis with a 20% acceptable failure rate compared to arthroscopic findings. Downward, upward, and horizontal cumulative summation trends indicated incompetence, exceptional competence, and competence, respectively. The diagnostic accuracy of third-year residents was compared with that of second-year residents and the number of cases required to gain self-confidence was evaluated. Results: Cumulative summation analysis showed that after 26–28 scans, residents achieved the competence to correctly diagnose supraspinatus tears: an upward trend was observed from the beginning for full-thickness tears and a downward trend was observed for partial-thickness tears. Sensitivity and specificity were 0.95 and 0.79, respectively, for third-year residents and 0.91 and 0.58, respectively, for second-year residents. Residents reported self-confidence after 30 ultrasound scans for the detection of rotator cuff tears. Conclusions The number of scans that novices needed to be competent for detecting rotator cuff tears was approximately 30 cases, and the diagnostic accuracy of third-year residents was significantly higher than that of second-year residents.

BACKGROUND/OBJECTIVES: Okra seed is a rich source of various nutritional and bioactive constituents, but its mechanism of action is still unclear. The aim of this study was to evaluated the effects on glucose uptake and serum lipid profiles of unsaponifiable matter (USM) from okra seed in adipocytes and diabetic animal models.MATERIALS/METHODSUSM was prepared from okra seed powder by saponification. The contents of phytosterols and vitamin E in USM were measured. 3T3-L1 preadipocytes were cultured for 6 days with different concentrations of USM (0–200 μg/mL). The diabetic rats were administered with or without USM for 5 wk. RESULTS: In the USM, the contents of phytosterols and vitamin E were 394.13 mg/g USM and 31.16 mg/g USM, respectively. USM showed no cytotoxicity and led to an approximately 1.4-fold increase in glucose uptake in 3T3-L1 adipocytes. The treatment of USM also increased the expressions of peroxisome proliferator-activated receptor-γ and glucose transporter-4 in a dose-dependent manner in adipocytes. The body weight change was not significantly different in all diabetic rats. However, blood glucose and the weights of liver and adipose tissues were significantly reduced compared to those in the control diabetic rats. Treatment with USM decreased the levels of triglycerides, total cholesterol, and low-density lipoprotein cholesterol compared to the control group. The USM group also showed significantly decreased atherogenic indices and cardiac risk factors. CONCLUSION These results suggest that USM from okra seed improves the hypoglycemic and hypolipidemic effects in diabetic rats, and provides valuable information for improving the functional properties of okra seed.
