RESUMO
BACKGROUND: To review the impact of the operating microscope (OM) for reconstruction of the hepatic artery (HA) by comparing the outcomes with standard loupe reconstruction (SL) in pediatric liver transplantation (LT). METHODS: Studies comparing the application of OM and SL for the reconstruction of the HA in primary pediatric LT were included from a systematic search of MEDLINE, Cochrane Library and EMBASE from inception to June 2022. Re-transplantation, dual grafts and auxiliary transplants were excluded. Primary outcome was the rate of HA thrombosis (HAT). Secondary outcomes were graft loss and mortality. RESULTS: There were 1261 liver recipients from 9 included studies published until June 2022. There were 484 patients in the OM group and 777 patients in the SL group. HAT incidence with OM was significantly lower with OR = 0.18 (95% CI: 0.07-0.48). The 1-year graft survival was significantly better in the OM group with OR = 2.77 (95% CI: 1.13-6.80). 1-year overall mortality was also significantly lower with OM with OR = 0.39 (0.18-0.86). The use of OM did not significantly impact the incidence of HAT in the living donor liver transplant subgroup. Differences in time for hepatic HA reconstruction, total operating time and length of hospital stay did not reach statistical significance. CONCLUSION: The use of OM has reduced the risk of HAT, graft loss and mortality in pediatric liver transplantation. Adoption of microsurgical principles in general may have contributed to the improved outcomes with SL reconstruction of HA in pediatric LT.
RESUMO
BACKGROUND Crusted scabies is a severe skin infection resulting from hyper-infestation with the obligate parasite Sarcoptes scabiei var. hominis. In contrast to classic scabies, crusted scabies may involve as many as hundreds to millions of mites. Importantly, this condition is associated with a mortality rate of 60% in 5 years, and is more likely to develop in immunosuppressed hosts, presumably due to an impaired T-cell response against the mite. CASE REPORT We present a case of crusted scabies in a 13-year-old girl during her early post-liver transplant period receiving immunosuppression successfully treated with topical 5% permethrin. She had pruritic erythematous papules, confirmed as scabies through skin scraping. The challenge of misdiagnosis during the initial presentation is noteworthy, given atypical manifestations and more common differentials. To our knowledge, only 2 cases of crusted scabies in pediatric solid-organ transplant recipients have been reported. Despite the absence of guidelines for pediatric solid-organ transplant recipients, urgent treatment is required due to the high associated mortality rates. In our case, early treatment proved successful without any secondary bacterial infections or clinical evidence of relapse during a 6-month follow-up. CONCLUSIONS We report a case of scabies in a pediatric liver transplant recipient that was successfully treated. It is crucial to consider the diagnosis of scabies given the associated morbidity and the risk of secondary bacterial infections among other more common differentials. Notably, the response to standard anti-scabies treatment may lead to resolution without relapse in pediatric solid-organ transplant recipients.

PURPOSE: The workup of jaundiced infants may be variable and protracted, thereby delaying the diagnosis and timely intervention for biliary atresia (BA). This potentially leads to inferior outcomes. We developed a practical score to stratify infantile cholestasis according to the risk of having BA. METHOD: The score (0-7) [gallbladder length ≤ 15 mm (+ 1), common bile duct (CBD) diameter < 0.5 mm(+ 1), pre-portal vein (PV) echogenicity(+ 1), direct-to-total bilirubin ratio (D/T) ≥ 0.7(+ 2), and gamma-glutamyl transferase (GGT) ≥ 200 IU/L(+ 2)] are derived from logistic regression of data from a retrospective cohort of cholestatic infants (n = 58, 41 BA) in our institution. It was then validated with a separate retrospective cohort (n = 28, 17 BA) from another institution. Final diagnoses were as per intraoperative cholangiogram (IOC) and liver histopathology. RESULTS: A cutoff score of ≥ 3 diagnosed BA with 100% and 94% sensitivity in the derivative cohort (area under receiver operating characteristic curve, AUROC 0.869) and validation cohort (AUROC 0.807), respectively. D/T ratio was the most sensitive (93%) and CBD diameter was the most specific (88%) parameter. The score accurately predicted non-BA in 11(65%) and 7(63%) infants in the derivative and validation cohorts, respectively, with one missed BA in the latter. CONCLUSION: We propose a validated, simple, yet sensitive diagnostic score to risk-stratify cholestatic infants, aiming to expedite definitive management of BA.

BACKGROUND Bilious vomiting in a child potentially portends the dire emergency of intestinal malrotation with volvulus, necessitating prompt surgical management, with differentials including small-bowel atresia, duodenal stenosis, annular pancreas, and intussusception. Although the upper-gastrointestinal series (UGI) is the diagnostic investigation of choice, up to 15% of the studies are inconclusive, thereby posing a diagnostic challenge. CASE REPORT We report a case series of 3 children referred for bilious vomiting, whose initial UGI was inconclusive and who were eventually confirmed to have intestinal malrotation at surgery. The first child was a female born at 37 weeks with antenatally diagnosed situs inversus and levocardia, who developed bilious vomiting on day 1 of life. The duodenojejunal flexure (DJ) could not be visualized on the UGI because of faint opacification on first pass of the contrast and subsequent overlap with the proximal jejunal loops. The second child was a male born at 36 weeks, presenting at age 4 months with bilious vomiting of 2 days duration. The third child was a female born at 29 weeks, presenting with bilious aspirates on day 3 of life. UGI for all 3 showed persistent hold-up of contrast at the proximal duodenum with no opacification of the distal duodenum or small bowel.Adjunctive techniques during the UGI and ultrasound examination helped achieve a preoperative diagnosis of malrotation in these children. CONCLUSIONS Application of diagnostic adjuncts to an inconclusive initial UGI may help elucidate a preoperative diagnosis of intestinal malrotation in infantile bilious vomiting.

BACKGROUND: Circumcision as a common elective pediatric surgery worldwide is a stressful and anxiety-inducing experience for parents and children. Although current perioperative interventions proved effective, such as reducing preoperative anxiety, there are limited holistic solutions using mobile apps. OBJECTIVE: This paper aims to describe the development and primary evaluation of an intelligent customer-driven smartphone-based app program (ICory-Circumcision) to enhance health outcomes among children undergoing circumcision and their family caregivers. METHODS: Based on the review of the literature and previous studies, Bandura's self-efficacy theory was adopted as the conceptual framework. A multidisciplinary team was built to identify the content and develop the apps. Semistructured interviews were conducted to evaluate the ICory-Circumcision. RESULTS: The ICory-Circumcision study was carried out from March 2019 to January 2020 and comprised 2 mobile apps, BuddyCare app and Triumf Health mobile game app. The former provides a day-by-day perioperative guide for parents whose children are undergoing circumcision, while the latter provides emotional support and distraction to children. In total, 6 participants were recruited to use the apps and interviewed to evaluate the program. In total, 4 main categories and 10 subcategories were generated from content analysis. CONCLUSIONS: ICory-Circumcision seemed to lean toward being useful. Revisions to ICory-Circumcision are necessary to enhance its contents and features before advancing to the randomized controlled trial.
