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.

Objective: To determine whether the bioimpedance analysis (BIA) ratios of upper to lower extremities could predict treatment outcomes after complex decongestive therapy (CDT) for gynecological cancer related lymphedema (GCRL). Methods: A retrospective study, from March 2015 to December 2018, was conducted. The study sample comprised patients receiving CDT, 30 minutes per day, for 10 days. Bioimpedance was measured pre- and post-CDT. Circumference measurements were obtained at 20 and 10 cm above the knee (AK) and 10 cm below the knee (BK). We calculated the expected impedance at 0 Hz (R0) of extremities and upper/lower extremity R0 ratios (R0U/L). We evaluated the relationship between R0U/L and changes in R0U/L and circumferences, pre- and post-CDT. Results: Overall, 59 patients were included in this study. Thirty-one lower extremities in 26 patients comprised the acute group, and 38 lower extremities in 33 patients comprised the chronic group. Pre-treatment R0U/L was significantly correlated with R0U/L change after adjusting for age and BMI (acute: R=0.513, p<0.01; chronic: R=0.423, p<0.01). In the acute group, pre-treatment R0U/L showed a tendency to be correlated with circumference change (AK 20 cm: R=0.427, p=0.02; AK 10 cm: R=0.399, p=0.03). Conclusion Our study results suggested that pre-treatment BIA could predict volume reductions after CDT in the early stages of GCRL. These findings implied that BIA value could be one possible parameter to apply in treatment outcomes prediction, during the early stage of GCRL. Therefore, further large-scale prospective studies will be beneficial.

The water-jet system (WJS) can be used for selective dissection of kidney parenchyma without renal artery clamping in laparoscopic partial nephrectomy (LPN). We report our experiences regarding LPN with a WJS. The first case was a 59 year old male with a 1.8 cm solid mass in the Rt. mid-lateral area (R.E.N.A.L score: 5a). The second case was a 24 year old female with a 2.3cm solid mass in the Lt. mid-lateral area (R.E.N.A.L score: 7x). We successfully finished non-clamping LPN using a WJS without perioperative complications. Surgical margins were negative (7mm and 1mm for cases 1 and 2, respectively). Post-operative renal function was not decreased significantly. LPN using a WJS is a feasible and safe technique which can be performed for small renal masses without ischemic damage.

PURPOSE: Partial nephrectomy has a similar oncologic outcome to radical nephrectomy while reducing cardiac and metabolic morbidity. However, previous studies reported that partial nephrectomy had been underutilized. The purpose of this study is to analyze trends in the use of partial nephrectomy in Korea and evaluate which individual factors and hospital factor influenced the operative approach. MATERIALS AND METHODS: Using URO-PDS database, 11560 patients underwent nephrectomy for renal cell carcinoma between 2006 and 2010 were identified. International Classification of Disease (ICD-9) diagnosis codes were applied to target subject of interest. Logistic regression was applied to identify determinants of partial nephrectomy. RESULTS: Over the study period, the proportion of partial nephrectomies has steadily increased from 9.4% in 2006 to 30.4% in 2010 (p<0.001). Deviation of utilization in partial nephrectomy has been observed based on the area (p<0.001) and type of surgery (p<0.001). Individual of younger age, as well as male, were more likely to be treated with partial nephrectomy (p<0.001 for each). Furthermore, Patient treated at hospitals with higher nephrectomy volume were more prone to be treated with partial nephrectomy (p<0.001 for each). CONCLUSIONS: Partial nephrectomies have been increasingly performed over the study period but are still underutilized.
