Postoperative suprachoroidal hemorrhage is an infrequent but devastating complication after non-valved aqueous drainage implant surgery and demonstrated a bimodal distribution. The final outcomes of either conservative management or surgical drainage of the hemorrhage remained poor.

To report the incidence and outcomes of eyes developing postoperative suprachoroidal hemorrhage (PSCH) after undergoing Aurolab Aqueous Drainage Implant (AADI) surgery for adult and pediatric refractory glaucomas.

In this retrospective series, case files of all patients who underwent AADI between May 2012 and December 2019 were retrieved from an electronic database. A PSCH was defined as the presence of hemorrhagic choroidal detachment, confirmed by ultrasound B scan, occurring in a closed system in the postoperative period.

Of the 986 eyes that underwent AADI during the study period, 7 (0.7%), developed PSCH (95% CI=0.3-1.6%). There were no differences in the preoperative parameters between those with and without PSCH. Ofnly about half these eyes.

A frozen neck is a scarred neck with severe fibrosis with a loss of tissue planes secondary to prior irradiation with or without surgery. The purpose of this study was to evaluate the outcomes of cervicofacial reconstruction in patients with soft tissue defects and bone flap and reconstruction plate exposure with the upper trapezius myocutaneous flap. Fifteen oncologic patients with prior surgery and radiotherapy developed soft tissue dehiscence with bone and osteosynthesis material exposure. All patients had either a frozen neck or a vessel-depleted neck. The soft tissue defects were reconstructed, the osteosynthesis material was removed and the bone flap exposure was covered in all patients. One patient developed a seroma and 1 patient reported wound dehiscence. In terms of esthetic results, 6 patients referred a good esthetic result, whereas 8 patients referred a fair result and 1 patient a poor result. Two patients with prior radical neck dissection reported a poor functional result in the ipsilateral s neck or a vessel-depleted neck. The soft tissue defects were reconstructed, the osteosynthesis material was removed and the bone flap exposure was covered in all patients. One patient developed a seroma and 1 patient reported wound dehiscence. In terms of esthetic results, 6 patients referred a good esthetic result, whereas 8 patients referred a fair result and 1 patient a poor result. Two patients with prior radical neck dissection reported a poor functional result in the ipsilateral shoulder, previously to secondary reconstruction. Functional neck dissection was performed in 10 patients, 8 patients referred a good functional outcome and 2 patients reported a fair result. The upper trapezius flap is an extremely reliable source for secondary cervicofacial soft tissue reconstruction in "frozen neck." In comparison with other locoregional flaps, the upper trapezius flap fulfills all aesthetic and functional criteria for secondary cervicofacial soft tissue reconstruction.

Accessory cranial sutures have been described in the literature and are most commonly associated with the parietal bone. These sutures are typically identified incidentally and there have been no reported cases of accessory cranial sutures leading to abnormal head shape.The authors present the case of a 3-month-old patient with multiple congenital anomalies and an accessory parietal suture leading to abnormal head shape. The patient was successfully treated with cranial orthotic therapy. To our knowledge, this is the first reported case of an accessory cranial suture leading to abnormal head shape.

In the surgical procedures such as osteotomy to be applied to ramus of the mandible, care should be taken not to damage the inferior alveolar nerve (IAN). The safe zone, which is the area above and behind the mandibular foramen (MF), is the ramus of mandible area, where these surgeries can be performed without damaging the inferior alveolar neurovascular bundle. It was aimed to determine the safe zone in the ramus of mandible in the cone-beam computed tomography (CBCT) images of individuals. The CBCT images of 300 Turkish individuals between the ages of 18 to 65 were bilaterally and retrospectively evaluated. Three parameters on the sagittal and two parameters on the axial plane were measured. Additionally, two ratios were calculated which determined the superior and posterior part of the safe zone through the measured parameters. In this study, the safe zone was determined as the area where 55% of the upper part and 49% of the posterior part of the mandibular ramus. Determining the safe zone in surgical prerent populations to determine standard values.

The main purpose of this study is to evaluate the accuracy of virtual endoscopy (VE) in microvascular decompression (MVD) for the treatment of trigeminal neuralgia (TN).

A total of 30 TN patients aged 42 to 70 years were recruited from January 2015 to January 2019, and all patients were confirmed to have severe neurovascular compression (NVC) (≥degree 2) by magnetic resonance tomographic angiography (MRTA). Preoperative MRTA and enhanced CT were performed, and the data were imported into Stlview software for VE simulation of MVD. The reliability of VE, real endoscopy, and MRTA in evaluating the degree and position of MVD in TN patients was compared.

Virtual endoscopy is more reliable than MRTA in evaluating the degree of NVC, but both of them are reliable in determining the position of NVC in TN patients.

Virtual endoscopy can be used in MVD for the treatment of TN, including preoperative diagnosis and risk evaluation, intraoperative guidance, and postoperative evaluation.

The purpose of this study was to describe the characteristics and compare the severity of head and neck injuries between public and backyard waterslides. This was a 20-year cross-sectional study of the National Electronic Injury Surveillance System. 4-Octyl Injuries from waterslides were included in this study if they involved the head, face, eyeball, mouth, neck, or ear. Patient and injury characteristics were compared by the type of waterslide using chi-squared and independent sample tests. A total of 1823 injury reports were identified (39.8% backyard waterslides and 60.2% public waterslides). The mean age at the time of injury was 13.2 years, and the majority of patients were white (74.2%) males (55.1%). The most common primary diagnoses were laceration (28.4%) and internal organ injury (27.2%). A greater proportion of backyard injuries involved the head (P < 0.01) and resulted in concussions (P < 0.01) or fractures (P = 0.04). The overall admission rate from the ED was 3.5%, and no fatalities were noted.ients were white (74.2%) males (55.1%). The most common primary diagnoses were laceration (28.4%) and internal organ injury (27.2%). A greater proportion of backyard injuries involved the head (P  less then  0.01) and resulted in concussions (P  less then  0.01) or fractures (P = 0.04). The overall admission rate from the ED was 3.5%, and no fatalities were noted. There were no significant differences in admission rates between injuries from backyard and public slides. Fatal or serious head and neck injuries appear to be uncommon with waterslide injuries. Backyard waterslides pose a greater likelihood of cranial injury, and this may relate to differences in riding habits between public and private waterslides.

Rodríguez-Rosell, D, Sáez de Villarreal, E, Mora-Custodio, R, Asián-Clemente, JA, Bachero-Mena, B, Loturco, I, and Pareja-Blanco, F. Effects of different loading conditions during resisted sprint training on sprint performance. J Strength Cond Res XX(X) 000-000, 2020-The aim of this study was to compare the effects of 5 loading conditions (0, 20, 40, 60, and 80% of body mass [BM]) during weighted sled sprint training on unresisted and resisted sprint performance and jump ability. Sixty physically active men were randomly assigned into 5 groups according to the overload used during sled sprint training 0% (G0%, n = 12), 20% (G20%, n = 12), 40% (G40%, n = 12), 60% (G60%, n = 12), and 80% BM (G80%, n = 12). Pretraining and post-training assessments included countermovement jump (CMJ), 30-m sprint without extra load, and 20-m sprint with 20, 40, 60, and 80% BM. All 5 experimental groups trained once a week for a period of 8 weeks completing the same training program (number of sessions, number of bouts, running interaction for resisted sprint performance at 80% BM condition, where the G40% group attained improvements in performance and G80% worsened. Moreover, G40% increased performance in unresisted and the rest of loading conditions. In addition, G0% and G60% showed statistically significant increases in unresisted sprint performance. No relevant changes were observed in the other experimental groups. All groups showed significant improvements (p less then 0.05-0.001) in CMJ height. Therefore, our findings suggest that resisted sprint training with moderate loads (i.e., 40% BM) may have a positive effect on unresisted and resisted sprint performance.

Seppänen, S and Häkkinen, K. Step vs. two-phase gradual volume reduction tapering protocols in strength training Effects on neuromuscular performance and serum hormone concentrations. J Strength Cond Res XX(X) 000-000, 2020-This study assessed effects of 2 reduced volume tapering protocols on neuromuscular performance and serum hormone concentrations in 14 recreationally strength-trained men (21-30 years). After an 8-week strength training period subjects were divided to the step (54% volume reduction immediately) and 2-phase gradual (38% reduction for the first week and 70% for the second week) tapering groups for 2 weeks. One repetition maximum (1RM) squat, maximal isometric bilateral leg press force (leg press MVIC), electromyography (EMG) of vastus lateralis (VL) and vastus medialis, cross-sectional area of VL, serum testosterone, cortisol, and sex hormone-binding globuline (SHBG) concentrations were measured before and repeatedly during training and tapering periods. Both tapering protocols led to signllows an overreaching period.

Correlations between jump performance in block and attack and the performance in official games, squat jumps, and countermovement jumps of professional volleyball players. J Strength Cond Res XX(X) 000-000, 2020-The jump used in performance tests must be chosen according to the specificity. The aims of the present study were to analyze the correlations between height and reach of block and attack jumps and the effectiveness of such actions in official games and also the relationship between height and reach of attack and block jumps and the height achieved in squat jump (SJ), countermovement jump (CMJ), and CMJ with an arms swing (CMJA). Thirteen, male, professional volleyball players who competed in the Brazilian Volleyball Super League participated in this study. Evaluations of height and reach of attack and block jumps and height of SJ, CMJ, and CMJA were performed. Attack and block effectiveness were evaluated in 8 official games.
