Objective Compare delivery room practices and outcomes of infants born at less than 32 weeks' gestation or less than 1,500 g who have plastic wrap/bag placement simultaneously during placental transfusion to those receiving plastic wrap/bag placement sequentially following placental transfusion. Study Design Retrospective analysis of data from a multisite quality improvement initiative to refine stabilization procedures pertaining to placental transfusion and thermoregulation using a plastic wrap/bag. Delivery room practices and outcome data in 590 total cases receiving placental transfusion were controlled for propensity score matching and hospital of birth. Results The simultaneous and sequential groups were similar in demographic and most outcome metrics. The simultaneous group had longer duration of delayed cord clamping compared with the sequential group (42.3 ± 14.8 vs. 34.1 ± 10.3 seconds, p < 0.001), and fewer number of times cord milking was performed (0.41 ± 1.26 vs. 0.86 ± 1.92 seconds, p < 0.001). The time to initiate respiratory support was also significantly shorter in the simultaneous group (97.2 ± 100.6 vs. 125.2 ± 177.6 seconds, p = 0.02). The combined outcome of death or necrotizing enterocolitis in the simultaneous group was more frequent than in the sequential group (15.3 vs. 9.3%, p = 0.038); all other outcomes measured were similar. Conclusion Timing of plastic wrap/bag placement during placental transfusion did affect duration of delayed cord clamping, number of times cord milking was performed, and time to initiate respiratory support in the delivery room but did not alter birth hospital outcomes or respiratory care practices other than the combined outcome of death or necrotizing enterocolitis.

Abstract Background and study aims Multiple large colorectal lesions are sometimes diagnosed during colonoscopy. However, there have been no investigations of the feasibility of simultaneous endoscopic submucosal dissection (ESD) for multiple lesions. This study aims to reveal the strategy of simultaneous ESD for multiple large colorectal lesions. Patients and methods 246 patients who underwent ESD for 274 colorectal lesions were retrospectively evaluated in this study. Fifty-one large colorectal lesions among 23 patients were treated by ESD simultaneously (simultaneous group), and 223 patients were treated with ESD for a single lesion (single group). Results En-bloc resection and curative resection rates did not differ. Compared with the single group, each procedure time was faster (31.8 ± 23.6 min vs. 45.8 ± 44.8, P = 0.002), but total procedure time was significantly longer in the simultaneous group (70.6 ± 33.4 vs. 45.8 ± 44.8 min, P = 0.01). Rates of adverse events including bleeding and perforation were not higher in the simultaneous group but the mean blood pressure, incidence of bradycardia and the amount of sedative drug used during ESD were significantly higher in the simultaneous group. Multiple logistic regression analysis identified non-experienced physician, lesion size ≥ 40 mm and submucosal fibrosis as an independent risk factor for procedure duration (≥ 90 min) (Odds ratio 11.852, 18.280, and 3.672; P < 0.05, respectively). Conclusions Simultaneous ESD for multiple synchronous colorectal lesions is safe and feasible compared with single ESD and can reduce the burden to patients, length of hospital stay and medical expense. These results need to be elucidated by further studies.

Abstract Introduction: Historically, the combination of primary and nodal surgeries for carcinoma penis is thought to increase the morbidity and hospital stay. Despite the modifications in surgery including modified inguinal lymphadenectomies, morbidity of the procedure is high. Methods: A prospective, nonrandomized study to analyze a total of 56 consecutive patients from 2006 to 2009, who were evaluated and underwent surgery for primary and nodes for carcinoma penis at our center, was done. The median follow-up was 34 months (range from 12 to 48 months). The procedures included both prophylactic and therapeutic groin dissections. Various parameters were tested using SPSS version 17 statistics software. Results: Duration of drains, hospital stay, wound morbidity, and long-term complications were found to be similar in the simultaneous and staged surgery groups. The mean duration of drains for the simultaneous group of 18 patients was 12.56 days and the corresponding duration of drains for the staged surgery group of 36 patients was 12.83 days. The minor morbidity and major morbidity for the simultaneous group were 27.8% and 38.9% and the corresponding figures for the staged group were 22.2% and 44.4%, respectively. The mean and median hospital stay for the simultaneous surgery group were 21.5 and 27.5 days, respectively. The mean and median hospital stay for the staged surgery group were 17.5 and 21.36 days, respectively. The study revealed no statistically significant difference between the two groups with regard to all the above parameters. Conclusions: Simultaneous surgery for the primary and nodes in carcinoma penis is very much feasible. Simultaneous and early-staged lymphadenectomy have no difference in results with respect to drain duration, hospital stay, wound morbidity, and long-term complications. Simultaneous lymphadenectomy can be combined with penectomy both in the prophylactic and therapeutic settings.

Category: Hindfoot Introduction/Purpose: Surgical correction of Stage 2 posterior tibial tendon dysfunction typically involves a combination of soft tissue and bony corrections, often including a medial displacement calcaneal osteotomy (MDCO). This osteotomy is often fixated utilizing two parallel screws; however, it remains unknown how much correction is lost based on various accepted drilling techniques for common fixation of this osteotomy. Our cadaveric study compares three different surgical drilling techniques, using two parallel cannulated screws for fixation, to best maintain desired translation of the MDCO. Methods: Fifteen above knee, fresh-frozen, matched pair cadaveric specimens (30 limbs) were randomized equally into three groups. Calcanealosteotomies were performed, followed by manual 10 mm medial translation of the tuberosity. Two parallel 2.5mm guide wires were advanced across the osteotomy site under fluoroscopy. The first group involved a ‘staggered’ drilling technique in which one guide wire was over drilled to the osteotomy site with a 4.5mm cannulated drill and then a 7.0 mm cannulated screw was placed across the osteotomy, followed by a second screw in similar fashion. The second, ‘simultaneous’ group consisted of over drilling both guide wires sequentially followed by placement of both screws. The third control group involved simultaneously over drilling only the near cortex, followed by placement of the 2 screws. Following screw fixation, the calcaneal tuberosity was manually translated in a lateral direction. The loss of correction was then marked and measured in millimeters. Results: All thirty cadaveric specimens underwent standard medializing calcaneal displacement osteotomy without significant variation, or complication. Loss of medialization was measured in millimeters following a manual lateral displacing force after the screw fixation of the osteotomy. The ‘simultaneous’ drilling group experienced the greatest loss of medial displacement with the mean loss of correction being 2.6 mm (range 1.37 - 3.48 mm) following manual lateral translation. The ‘staggered’ group showed an average loss of 1.16 mm (range 0.36 - 2.67 mm). The control group, that simply involved drilling of the near cortex, demonstrated the greatest maintenance of medial displacement with a mean loss of only 0.036 mm (range 0.01 - 0.06 mm). Conclusion: Our cadaveric study comparing three different drilling techniques for maintaining the intended correction following MDCO demonstrates that simultaneous over drilling of only the tuberosity near cortex prior to screw fixation was the most resistant to loss of medial displacement; whereas mean loss of correction with simultaneous drilling of both wires to the osteotomy resulted in the greatest loss of correction at an average of 26%.
