BACKGROUND: We designed this study to determine whether trauma history and initial assessment anticipate the injury severity of the free-fall patient. METHODS: Two hundred patients who admitted emergency department of Severance hospital because of the fall from a height were enrolled in this study. The height of fall, the body orientation, and the characteristics of impacted material, and the Injury Severity Score(ISS) were evaluated by retrospective chart reviews. And regression equations were determined for predicting ISS on the basis of clinical parameters using multiple regression analysis. RESULTS: According to the characteristics of impacted material, the ISS was higher in the hard surface(13.7+/-9.5) than the sort surface(10.5+/-8.8)(p<0.05). There were correlations between height of fall and ISS(p<0.01, r=0.5). To the body orientation, the ISS was higher in the head-to-feet orientation(18.211.7) than the feet-to-head(10.9+/- 7.0) or other position(8.5+/-5.8)(p<0.01). The regression equations were as follows, ISS=2 +0.082xage(year)-1.54x(Glasgow Coma Scale)-3x(feet-to-head orientation)+0.65x height of fall(m)+2.7 x (hand surface)(p<0.01, R2=0.53). CONCLUSION: This study suggest that the injury severity of patient with free fall are significancy related to the height of fall, the characteristics of impacted material and the body orientation.

Lobectomy with mediastinal node dissection has been standard treatment for non-small cell lung cancer (NSCLC). Nowadays, video-assisted thoracoscopic surgery (VATS) is gaining acceptance as an alternative treatment option, given the quality-of-life benefits that it confers. For the VATS procedure, most surgeons create two or three ports with a utility incision of 3 to 5 cm. However, with acquired skill and instrumentation advances, single-incision thoracoscopic surgery has emerged over time. Here, we report the case of an 86-year-old female with NSCLC treated by single-incision segmentectomy.

Background: The recently introduced super-resolution (SR) deep learning image reconstruction (DLR) is potentially effective in reducing noise level and enhancing the spatial resolution. We aimed to investigate whether SR-DLR has advantages in the overall image quality and intensity homogeneity on coronary computed tomography (CT) angiography with four different approaches: filtered-back projection (FBP), hybrid iterative reconstruction (IR), DLR, and SR-DLR. Methods: Sixty-three patients (mean age, 61 ± 11 years; range, 18–81 years; 40 men) who had undergone coronary CT angiography between June and October 2022 were retrospectively included. Image noise, signal to noise ratio, and contrast to noise ratio were quantified in both proximal and distal segments of the major coronary arteries. The left ventricle myocardium contrast homogeneity was analyzed. Two independent reviewers scored overall image quality, image noise, image sharpness, and myocardial homogeneity. Results: Image noise in Hounsfield units (HU) was significantly lower (P < 0.001) for the SR-DLR (11.2 ± 2.0 HU) compared to those associated with other image reconstruction methods including FBP (30.5 ± 10.5 HU), hybrid IR (20.0 ± 5.4 HU), and DLR (14.2 ± 2.5 HU) in both proximal and distal segments. SR-DLR significantly improved signal to noise ratio and contrast to noise ratio in both the proximal and distal segments of the major coronary arteries.No significant difference was observed in the myocardial CT attenuation with SR-DLR among different segments of the left ventricle myocardium (P = 0.345). Conversely, FBP and hybrid IR resulted in inhomogeneous myocardial CT attenuation (P < 0.001). Two reviewers graded subjective image quality with SR-DLR higher than other image recon‑ struction techniques (P < 0.001). Conclusions SR-DLR improved image quality, demonstrated clearer delineation of distal segments of coronary arter‑ ies, and was seemingly accurate for quantifying CT attenuation in the myocardium.

Although many prosthetic materials exist for fabrication of implant-supported telescopic overdentures, available materials have not been thoroughly evaluated from a functional standpoint. This case report describes the use of polyaryletherketone (PAEK) based polymer for an implant-supported telescopic overdenture, a seldom used material in dentistry. This material is lighter than traditional materials, can accommodate changes in retentive forces, and is an easily retrievable by CAD/CAM fabrication. This case highlights the possibility of using new polymer materials for implant-supported telescopic overdentures.

PURPOSE: We analyzed the cases of supracondylar-intercondylar femoral fracture treated with retrograde intramedullary nail and report the clinical results and its usefulness. MATERIALS AND METHODS: We reviewed 17 cases of supracondylar-intercondylar femoral fracture that had been treated with retrograde intramedullary nail and each of patients had been followed up for a minimum one year. Post-operative functional assessment was performed using a scale developed by Sanders et al. The evaluation scale assesses range of motion, pain, walking ability, return to work, and alignment and shortening as measured on radiograph. RESULTS: According to functional assessment of Sanders et al, there were 6 excellent, 9 good, 1 fair, and 1 poor results, that is, 94% showed above excellent results. Bony union was obtained in average 5 months after operation. The post-operative complications were varus deformity in 1 case, wound infection in 1 case, stiffness of knee joint in 1 case, and metal failure in 1 case. CONCLUSION: The treatment of supracondylar-intercondylar femoral fracture with retrograde intramedullary nail is one of the good surgical options for clinically preferable results with the advantages in early joint motion and early ambulation.

OBJECTIVE: The aim of this study is to assess the relationships between maternal plasma and umbilical cord leptin concentrations and their effects on newborn birth weights, maternal body mass indices and fetal sex in term normotensive (NT) and preeclampsia (PE) women. METHODS: Blood samples were obtained at delivery from 20 NT group and another 20 from PE group of at least 36 weeks of gestation. And the umbilical cord samples were also taken from their newborns at birth. Plasma leptin levels were determined in both groups using a human recombinant leptin 125-I radioimmunoassay. RESULTS: Mean maternal plasma and umbilical cord leptin concentrations were 16.16+/-2.05 ng/ml and 7.11+/-1.01 ng/ml in NT group, 17.09+/-1.67 ng/ml and 8.55+/-6.63 ng/ml in PE group, and there was no statistical significances among them. The differences of leptin concentrations in maternal plasma and umbilical cord according to baby sex were not significant in both NT and PE groups. Plasma leptin concentrations were related with maternal weight gain and BMI in NT group and with body weight in PE group. The BMI and birth weights of the neonates have significant effects on the umbilical cord leptin concentrations in both NT and PE groups. CONCLUSION: In this study, no correlation was found between maternal plasma and umbilical cord leptin concentrations in both NT and PE groups. But maternal plasma leptin concentrations had positive correlations with maternal body weight, BMI, and body weight changes during pregnancy in both NT and PE groups. There were also positive correlations among umbilical cord leptin concentrations, BMI and birth weights of the neonates of NT and PE groups term. Therefore umbilical cord leptin is considered to be the index of fetal birth weight.
