Objective: To identify risk factors associated with accidental fetal skin lacerations (AFL) during cesarean section (CS). Methods: This retrospective cohort study was obtained from the registry of two large medical centers between 2014 and 2019. The study group comprised all newborns identified with AFL. The rates of various potential risk factors were compared between the study group and a group of CS at which no AFL had occurred (the control group). Results: Of the 14 666 CS deliveries, 48 cases of AFL (0.33%) were documented, 52% of these following urgent CS. Compared with the control group (n = 14 618), the only risk factors associated with AFL were premature rupture of membranes (PROM) (odds ratio [OR] 5.38, 95% convidence interval [CI] 2.97–9.74) and meconium‐stained amniotic fluid (OR 6.50, 95% CI 2.55–16.54). In subgroup analysis by CS urgency, no significance for these factors was noted in elective CS group; but higher rates of both PROM and meconium‐stained amniotic fluid were noted in the AFL during urgent CS (OR 14.23, 95% CI 6.30–32.16 and OR 15.36, (95% CI 5.65–41.75, respectively). Conclusions: During urgent CS, the surgeon should bear in mind that the presence of PROM or meconium‐stained amniotic fluid should prompt extra care and application of preventive measures to decrease the rates of AFL. Synopsis: Premature rupture of membranes and meconium‐stained amniotic fluid increase the risk for accidental fetal lacerations during urgent cesarean delivery. [ABSTRACT FROM AUTHOR]

Background: Auricular keloids belong to the most perplexing medical conditions, which have significant psychosocial impact on the patient's body image and quality of life. Summary: The article is purposed to provide dermatologists and plastic surgeons with the best proven practice using intralesional cryosurgery for the treatment of the different auricular keloid types in order to obtain superior clinical results by minimizing the probability of recurrence. In the past 20 years, the authors have developed novel procedures in order to increase the effectiveness of intralesional cryosurgery on auricular keloids, including hydrodissection, warm gauze technique, and excision of dangling skin. Long-lasting clinical results with a low recurrence rate and a satisfactory aesthetic outcome are achieved with no deformation of the ear framework. [ABSTRACT FROM AUTHOR]

Burn injuries have grave consequences for patients and impose a heavy economic burden on healthcare services. Studies on the epidemiology of burn injury in Israel are sparse and outdated, and improved understanding of current trends can help experts plan prevention campaigns and design effective treatment paradigms. This study sought to assess the background, clinical, and treatment characteristics of adult patients admitted with burn injury to a level 1 trauma center in Israel in 2005 to 2017. Data were retrospectively retrieved from the hard copy and electronic files as follows: patient sex and age; burn type, degree, and etiology; percentage total BSA (%TBSA) affected; and type of treatment and length of hospital stay (LOS). The cohort included 734 patients of mean age 41.79 years and a male-to-female ratio of 1.8:1. Thermal factors, particularly hot liquids, were the most common cause; second-degree burns were the most common. Mean %TBSA was 5.39%; mean LOS was 11.81 days; and mean LOS/%TBSA was 4.65. Advanced dressings alone yielded satisfactory outcome in 74.2% of patients. The relatively younger patient age and male predominance of our cohort were in line with published findings. The LOS was similar to previous studies in Israel but lower than in Europe. The LOS/%TBSA was higher than in the literature, with a decrease over time suggesting an increased effectiveness of treatment. There appears to be a decline in the rate of surgery for burn injury and increased expertise in the use of advanced dressings. National prevention campaigns should focus on scalds rather than flame-induced burns. [ABSTRACT FROM AUTHOR]

Introduction: During the last two decades, in parallel to the increased prevalence of bariatric procedures, there has been a marked increase in the prevalence of abdominoplasty surgery in the United States, and in accordance an increase in the scientific and clinical research related to all aspects of this technique. The most common complication of abdominoplasty is the formation of post-operative seroma. Various theories have been raised regarding the pathophysiology of seroma formation, and numerous methods for seroma prevention have been employed and tested. In the early 90's, a new theory argued that post-operative seroma formation is secondary to damage caused to the abdominal wall's lymphatic drainage during flap undermining. In light of this theory, a new surgical technique was suggested to execute the flap undermining in a more superficial plane. This enabled the preservation of the scarpa fascia and the deep adipose compartment, which preserved the integrity of the abdominal wall lymphatic collectors. This method was successful in reducing the rate of postoperative seroma formation. Recent studies have shed new light on the anatomy of the abdominal lymphatic collectors, pathophysiology of seroma formation and methods of its prevention. This new data undermines the foundations of the scarpa fascia preservation theory, and the surgical technique that was derived from it. A new theory that tries to settle the contradiction between the clinical success of the technique in reducing seromas and the new findings regarding abdominal wall's lymphatic collectors anatomy, is the presence of a 'sticky interface' between the deep adipose compartment and the flap.

We report on an artificially intelligent nanoarray based on molecularly modified gold nanoparticles and a random network of single-walled carbon nanotubes for noninvasive diagnosis and classification of a number of diseases from exhaled breath. The performance of this artificially intelligent nanoarray was clinically assessed on breath samples collected from 1404 subjects having one of 17 different disease conditions included in the study or having no evidence of any disease (healthy controls). Blind experiments showed that 86% accuracy could be achieved with the artificially intelligent nanoarray, allowing both detection and discrimination between the different disease conditions examined. Analysis of the artificially intelligent nanoarray also showed that each disease has its own unique breathprint, and that the presence of one disease would not screen out others. Cluster analysis showed a reasonable classification power of diseases from the same categories. The effect of confounding clinical and environmental factors on the performance of the nanoarray did not significantly alter the obtained results. The diagnosis and classification power of the nanoarray was also validated by an independent analytical technique, i.e., gas chromatography linked with mass spectrometry. This analysis found that 13 exhaled chemical species, called volatile organic compounds, are associated with certain diseases, and the composition of this assembly of volatile organic compounds differs from one disease to another. Overall, these findings could contribute to one of the most important criteria for successful health intervention in the modern era, viz. easy-to-use, inexpensive (affordable), and miniaturized tools that could also be used for personalized screening, diagnosis, and follow-up of a number of diseases, which can clearly be extended by further development., Competing Interests: The authors declare no competing financial interest.
