Background: Infections in neonates with herpes simplex virus 1 (HSV-1) following circumcision due to Metzitzah Be'Peh (MBP) performed by a Mohel occur each year in small numbers. One solution to this problem is the use of a mucus extractor device instead of MBP, which has been authorized by some rabbis. Yet, using a mucus extractor remains controversial among ultra-Orthodox Jews; thus, creating a need for additional solutions.
Objectives: To seek to reduce HSV-1 infection of neonates due to MBP.
Methods: We tested several oral rinse solutions for their ability to destroy virus infectivity following incubation for 30 seconds and using plaque reduction assays.
Results: Corsodyl, Decapinol, and Listerine® all destroyed plaques formation of spiked virus, while Gengigel and Tantum Verde were found to be less effective. We focused specifically on Listerine® due to its efficacy in eliminating contagious HSV-1 from saliva after a 30-second oral rinse. Five different products of Listerine® reduced the infectivity of a spiked virus by more than 4 orders of magnitude in 30 seconds. We also showed that Listerine (up to 7% v/v) can stay in the mouth but did not harm living cells and therefore will not cause any damage to the injured tissue.
Conclusions: Significant reduction in cases of infection with HSV-1 due to MBP can be achieved if Mohalim consistently adopt the practice of careful mouth washing with Listerine® just before performing MBP.

Background: Accuracy of the number and location of pathological lymph nodes (LNs) in the pathology report of a neck dissection (ND) is of vital importance.
Objectives: To quantify the error rate in reporting the location and number of pathologic LNs in ND specimens.
Methods: All patients who had undergone a formal ND that included at least neck level 1 for a clinical N1 disease between January 2010 and December 2017 were included in the study. The error rate of the pathology reports was determined by various means: comparing preoperative imaging and pathological report, reporting a disproportionate LN distribution between the different neck levels, and determining an erroneous location of the submandibular gland (SMG) in the pathology report. Since the SMG must be anatomically located in neck level 1, any mistake in reporting it was considered a categorical error.
Results: A total of 227 NDs met the inclusion criteria and were included in the study. The study included 128 patients who had undergone a dissection at levels 1–3, 68 at levels 1–4, and 31 at levels 1–5. The best Kappa score for correlation between preoperative imaging and final pathology was 0.50. There were nine cases (3.9%) of a disproportionate LN distribution in the various levels. The SMG was inaccurately reported outside neck level 1 in 17 cases (7.5%).
Conclusions: At least 7.5% of ND reports were inaccurate in this investigation. The treating physician should be alert to red flags in the pathological report

Background: Pilonidal disease in the natal cleft is treated traditionally by a wide and deep excision of the affected area. There is growing awareness, however, to the advantages of minimally invasive surgeries.
Objectives: To compare the efficacy of wide excision operations and minimal trephine surgery in patients with primary pilonidal disease.
Methods: In this retrospective study we examined surgical and inpatient records of 2039 patients who underwent surgery for primary pilonidal disease in five private hospitals between 2009 and 2012. Most procedures were of lay-open, primary midline closure, and minimal surgery types. Pilonidal recurrence rates were evaluated in a subset of 1260 patients operated by 53 surgeons each performing one type of surgery, regardless of patient characteristics or disease severity.
Results: With a mean follow-up of 7.2 years, 81.5%, 85%, and 88% of patients were disease-free after minimally invasive surgery, wide excision with primary closure, and lay-open surgery, respectively, with no statistically significant difference in recurrence rates. Minimal surgeries were usually performed under local anesthesia and involved lower pain levels, less need for analgesics, and shorter hospital stays than wide excision operations, which were normally performed under general anesthesia. The use of drainage, antibiotics, or methylene blue had no effect on recurrence of pilonidal disease.
Conclusions: Minimally invasive surgeries have the advantage of reducing the extent of surgical injury and preserving patient’s quality of life. They should be the treatment of choice for primary pilonidal disease

Background: Pilonidal sinus is a chronic, inflammatory condition. Controversy exists regarding the best surgical management for pilonidal sinus, including the extent of excision and type of closure of the surgical wound.
Objectives: To assess the short- and long-term outcomes and success rate of the trephine procedure for the treatment of pilonidal sinus.
Method: A retrospective observational cohort study was conducted at a single center. Patients who underwent trephine procedure between 2011 and 2015 were included. Data collection included medical records review and a telephone interview to establish long-term follow-up.
Results: A total of 169 patients underwent the trephine technique for the repair of pilonidal sinus. Follow-up included 113 patients, median age 20 years. Initial postoperative period, 35.6% recalled no pain and 58.6% reported a mild to moderate pain. Postoperative complications included local infection (7.5%) and mild bleeding (15.1%). On early postoperative follow-up, 47.1% recalled no impairment in quality of life, and 25%, 21.2 %, and 6.7% had mild, moderate and sever disturbance respectively. The median time to return to work or school was 10 days. At a median follow-up of 29 months (IQR 19–40), recurrence rate was 45.1% (51/113), and 38 (33.9%) of the patients underwent another surgical procedure. Overweight, smoking, and family history were associated with higher recurrence rate.
Conclusion: The trephines technique has a significant long-term recurrence rate. Short-term advantages include low morbidity, enhanced recovery, and minimal to mild postoperative impairment to quality of life. The trephine procedure may be justified as a first treatment of pilonidal disease

Background: The diagnosis of atrial fibrillation (AFIB) related cardiomyopathy relies on ruling out other causes for heart failure and on recovery of left ventricular (LV) function following return to sinus rhythm (SR). The pathophysiology underlying this pathology is multifactorial and not as completely known as the factors associated with functional recovery following the restoration of SR.
Objectives: To identify clinical and echocardiographic factors associated with LV systolic function improvement following electrical cardioversion (CV) or after catheter ablation in patients with reduced ejection fraction (EF) related to AFIB and normal LV function at baseline.
Methods: The study included patients with preserved EF at baseline while in SR whose LVEF had reduced while in AFIB and improved LVEF following CV. We compared patients who had improved LVEF to normal baseline to those who did not.
Results: Eighty-six patients with AFIB had evidence of reduced LV systolic function and improved EF following return to SR. Fifty-five (64%) returned their EF to baseline. Patients with a history of ischemic heart disease (IHD), worse LV function, and larger LV size during AFIB were less likely to return to normal LV function. Multivariant analysis revealed that younger patients with slower ventricular response, a history of IHD, larger LV size, and more significant deterioration of LVEF during AFIB were less likely to recover their EF to baseline values.
Conclusions: Patients with worse LV function and larger left ventricle during AFIB are less likely to return their baseline LV function following the restoration of sinus rhythm.

Background: Achieving laparoscopic competency is challenging. Common laparoscopic simulators usually fall short in achieving true simulation.
Objective: To present a live porcine model laparoscopic skills laboratory for training general surgery residents.
Methods: An in vivo porcine laparoscopic model course was developed to simulate seven different laparoscopic procedures and seven laparoscopic skills for trainees under the tutelage of laparoscopic specialists.
Results: A total of 98 surgical trainees from 19 training programs underwent a full-day course from September 2017 to July 2020. Each program consisted of four trainees and two faculty members. In total, 175 laparoscopic procedures were performed. Trainees reported that the course improved their ability to perform in the operating room.
Conclusions: Using a laparoscopic porcine model in a guided didactic course performing complete common laparoscopic procedures in simulated operating room surroundings was beneficial for surgical trainees. The porcine model mimics human abdominal anatomy and allows trainees to increase their comfort level in performing such procedures.
