Background Few studies have evaluated the efficacy of short-term medical missions. This study was aimed to evaluate complication rates and determine the effects of protocol changes in a pediatric inguinal hernia campaign in Equatorial Guinea and analyze post-operative follow-up capacity. Methods In this prospective observational cohort study, we evaluated two patient cohorts (group A, 2017–2018; group B, 2019) treated during campaigns in Equatorial Guinea for congenital inguinal pathology (hernia, hydrocele, and cryptorchidism). Patients aged Results In stage 1, complication and surgical site infection (SSI) rates were 21.3% and 7.4% in group A (n = 94), and 5.8% (p p = 0.012) in the control group, respectively. Group A had 20.2% loss-to-follow-up. In group B (n = 62), 6-month postoperative follow-up could not be assessed owing to restrictions due to the COVID-19 pandemic, so only early complications were considered in stage 2, were complication and surgical site infection rates were 18.1% and 7.4% in group A and 11.3% (p = 0.350) and 1.6% (p = 0.150) in group B. Conclusion Our results showed higher than expected complication rates. Pre-operative prophylactic antibiotic could not show to reduce SSI. Further studies are needed to reduce complication rates in these campaigns. Patient loss-to-follow-up ratio warrants considering new strategies.

AIM: The aim of this study was to describe the incidence of complicated appendicitis during the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic lockdown. METHODS: This was a retrospective study of pediatric patients diagnosed with acute appendicitis in a single pediatric institution that assumed care responsibility for most of the pediatric emergencies during the lockdown period in Madrid (Spain). A control group was made up of the same number of patients diagnosed the previous year. RESULTS: One hundred fifty-one patients diagnosed with acute appendicitis were included (77 during self-quarantine and 74 during the previous year). The incidence of complicated appendicitis was 38.9% versus 28.3%, showing no significant differences. The 2 groups were homogeneous, with no differences in time elapsed between symptom onset and first emergency department visit, laboratory test results, median length of stay, intensive care admissions, or patients correctly diagnosed on their first visit. CONCLUSIONS: COVID-19 (coronavirus disease 2019) self-quarantine has not increased the incidence of complicated appendicitis, and children who developed complicated appendicitis did not have worse clinical outcomes. Parents did not delay presenting for medical attention, and emergency department pediatricians did not fail to diagnose this condition. Reorganization of hospital resources, fast-track treatment protocols for noncomplicated appendicitis, and extended use of home-stay hospitalization for complicated appendicitis could have contributed to these favorable outcomes.

Background To describe the complications and long-term results in patients with multiple endocrine neoplasia type 2A (MEN 2A) syndrome in whom a prophylactic thyroidectomy was performed, in relation to the recommendations of the American Thyroid Association (ATA). Methods A retrospective study of 14 patients with MEN 2A thyroidectomized between 2000 and 2017. We reviewed demographic, clinical, analytical and radiological data. Postoperative complications and long-term follow-up were analyzed. Results We treated eight boys and six girls with a median age of 5 years old (range 2–10). The predominant genetic mutation belonged to codon 634 (8/14, 57.14%). Total thyroidectomy (TT) without cervical lymphadenectomy was performed in all patients. A right upper parathyroidectomy was performed in one patient due to intraoperative suspicion of increased volume. Histological study revealed no alterations. Two patients presented transient hypocalcemia postoperatively and no patient had permanent hypocalcemia or nerve damage. Pathological anatomy confirmed medullary thyroid microcarcinoma in 5/14 patients: all carrying codon 634 mutation and three of them with preoperative basal calcitonin levels Conclusions Prophylactic thyroidectomy without cervical lymphadenectomy is an effective and safe preventive treatment in patients with MEN 2A syndrome when it is performed by experienced surgeons in reference centers.
