Abscess in the thyroid gland is a rare but severe infectious disease in children. Risk factors include anatomic abnormalities or underlying conditions; either inflammatory (Hashimoto thyroiditis) or postraumatic. Treatment requires endovenous antibiotics and usually children undergo surgery for drainage and eventual reparations of associated malformations. Pathogens vary considerably depending on the main predisposing thyroid illnesses.

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 < 18 years treated in referral campaigns were included. Complications occurring up to 6 months post-operatively were evaluated. Two stages were defined: Stage 1, wherein, complication rate in group A was compared to that in a control group from a tertiary hospital in Spain (with a case-control ratio of 1:2, paired according to age, sex and diagnosis); stage 2, wherein, complication rates between groups A and B were compared. Group B received a single dose of prophylactic amoxicillin-clavulanic acid. Follow-up capacity was assessed through follow-up appointments., 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  < 0.001) and 0.5% ( 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., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s) 2023.)

Objective: To study gastroesophageal reflux (GER) in children undergoing gastrostomy in a single pediatric institution., Material and Methods: A retrospective study of patients undergoing gastrostomy from 2000 to 2017 was carried out. Demographic data, clinical data, progression, and complications were recorded. GER was considered positive in patients with clinical signs requiring antisecretory treatment, prokinetic treatment, or anti-reflux surgery to control symptoms., Results: 207 patients with a median age of 2 years [R: 0.25-18] were included. Neurological impairment was the most frequent underlying condition (74%). Swallowing difficulty and undernourishment were the main surgical indications for gastrostomy. Prior to gastrostomy, 96 out of 207 patients (46%) showed GER symptoms. Combined fundoplication and gastrostomy was performed in 41 (43%) patients with preexisting GER, 6 of whom showed GER worsening (4 required redo fundoplication). 5 complications following fundoplication were noted - gastric perforation, sustained Dumping syndrome, and gastroesophageal stenosis. 55 out of 96 (57%) patients with preexisting GER underwent gastrostomy alone. Clinical signs disappeared in 16 of them (29%) and improved or stabilized in 19 (35%). GER worsening occurred in 20 patients (36%), with subsequent fundoplication being required in 10 cases. In patients with no previous clinical signs (111 out of 207), GER symptoms occurred following gastrostomy in just 18 cases (16%), and only 2 patients required fundoplication., Conclusions: In our experience, routine anti-reflux surgery combined with gastrostomy is not justified. Individualized fundoplication should be considered in case of medical treatment failure. Further studies with an adequate design are required to establish which patients could really benefit from this procedure.

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., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objective: To describe our experience in the diagnostic and therapeutic management of patients with acute abdomen as the main manifestation of SARS-CoV-2 infection., Material and Methods: A descriptive study of patients with clinical signs of acute abdomen diagnosed with COVID-19 and admitted at out healthcare facility from April 1 to May 10, 2020 was carried out. Clinical records were reviewed for data collection purposes., Results: A series of 14 patients (9 male and 5 female) with a median age of 9.5 years was analyzed. All patients had abdominal pain. There were 11 patients with fever, 9 patients with vomit or diarrhea, and 9 patients with clinically suspected surgical pathology (acute appendicitis or peritonitis). Increased acute phase reactants and coagulation disorders were a common characteristic at blood tests. An abdominal ultrasonography was carried out in all patients, and a CT-scan was performed in 4 patients, which demonstrated inflammatory signs in the terminal ileum, the ileocecal valve and the ascending colon, as well as gallbladder edema. Conservative management was decided upon in all patients except one, and eight patients required intensive care admission for support treatment., Conclusions: Gastrointestinal symptoms can be the primary manifestation of the new coronavirus infection, which simulates an acute abdomen with a potentially unfavorable evolution. For an accurate diagnosis to be achieved, a good clinical record and a comprehensive physical exploration, as well as complementary tests in search of characteristic findings of COVID-19, should be carried out.

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 <20 pg/mL. No recurrences or metastases have been detected after a mean follow-up of 8 years. A patient with codon 634 mutation developed a unilateral pheochromocytoma at 25 years of age. No patient has presented hyperparathyroidism. 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.

Objectives: To estimate the recurrence rate of intussusception after successful enema reduction and to analyze the costs of hospital admission with the current management of this pathology., Material and Methods: A retrospective study over 5 years of 97 patients with confirmed diagnosis of intussusception was undertaken. Medical records were evaluated for patient demographic, clinical and radiological data. Patients with enema-reduced intussusception were selected and data respecting to timing and outcome of recurrences, and length of stay were analyzed. Recurrence was defined as a new episode of intussusception within 72 hours of the initial presentation. Costs were calculated using hospital-specific data., Results: During the study period there were 81/97 children with successful enema reduction. Mean length of stay was 35 hours in the conservative treatment group. There were 8 episodes of recurrence, 5 of them within the first 24 hours (6.17%), for an overall recurrence rate of 9.88%. 7 children were treated by repeated enema and only one patient needed surgery for persistent illness. Assuming the overall recurrence rate of 9.88%, it would require hospitalizing 16 patients to identify a single recurrence with a cost of 1,723.75 € per patient., Conclusions: Given the low recurrence rate for enema-reduced intussusception and the possibility of repeated enema for their treatment in most of recurrences, we strongly advocated for the outpatient management as a safe and cost-effective alternative.
