Background: Many treatments for abdominal pain-related disorders of gut-brain interaction (AP-DGBI) in children have been studied. We aimed to assess the efficacy and safety of all known treatment options for paediatric AP-DGBI.

Methods: For this systematic review and network meta-analysis, we searched Embase, MEDLINE, and CENTRAL databases from inception to Jan 16, 2025, for published randomised controlled trials. We included trials of any treatment for AP-DGBIs (irritable bowel syndrome, functional abdominal pain-not otherwise specified, and abdominal migraine, excluding functional dyspepsia) in children aged 4-18 years. We excluded randomised controlled trials that solely included children with functional dyspepsia, but we included studies in which children with functional dyspepsia were included alongside children with the other AP-DGBI diagnoses and outcome data could not be separated. Data extraction and quality appraisal were performed in duplicate. The primary outcome for this network meta-analysis was author-defined treatment success. Network meta-analysis methodology was used within a frequentist framework using multivariate meta-analysis and outcomes were assessed using the Grading of Recommendations, Assessment, Development and Evaluation methodology. Clinical relevance of effect sizes was interpreted according to consensus definitions.

Findings: Of 19 337 records identified through the database search, 155 records representing 91 original randomised controlled trials were included in the network meta-analysis: these 91 trials comprised 7226 participants (4119 females and 2673 males). 12 studies assessed dietary treatments (n=730), 25 assessed pharmacological treatments (n=2140), 23 assessed probiotic treatments (n=1762), and 35 assessed psychosocial treatments (n=2952). Two treatments were probably more effective for treatment success than control treatments (moderate certainty): hypnotherapy (risk ratio [RR] 4·99 [95% CI 2·15 to 11·57]; large effect size) and cognitive behavioural therapy (CBT; RR 1·99 [95% CI 1·33 to 2·98]; moderate effect size). All other treatments evaluated for treatment success were either not effective or the data were of very low certainty and thus no conclusions could be made.

Interpretation: Hypnotherapy and CBT show moderate certainty for treatment efficacy with clinically relevant effect sizes. No conclusions can be made about the other therapies and treatment success due to very low evidence certainty. Future randomised controlled trials should focus on improving the evidence certainty for those other therapies with regard to core AP-DGBI outcomes.

Acute Abdomen in the Modern Era

Author/s: 
Selwyn O Rogers Jr, Orlando C Kirton

Acute abdominal pain is one of the most common symptoms in patients presenting to the emergency department and accounts for 5 to 10% of all emergency department visits. Pathophysiological conditions that lead to surgical interventions in such patients are mainly gastrointestinal obstruction, hemorrhage, ischemia, and viscus perforation. Acute abdominal pain can be diffuse or localized (i.e., quadrant-based epigastric pain or pain in the right upper quadrant, left upper quadrant, right lower quadrant, or left lower quadrant)2,4,6 and is associated with but not limited to the following disease processes: perforated viscus, peptic ulcer disease, mesenteric ischemia, acute cholecystitis, appendicitis, diverticulitis, pancreatitis, and intraabdominal hemorrhage. The need for emergency general surgery is an independent risk factor for postoperative complications and death, indicating the severity of the condition. Therefore, timely diagnosis of acute abdominal emergencies is essential. From antiquity to modern times, medical students have been taught that the history and the physical examination are the central components in the evaluation of acute abdominal pain.

A challenging diagnosis: hereditary angioedema presenting during pregnancy

Author/s: 
Chair, I., Lacuesta, G., Nash, C. M., Cook, V.

• Hereditary angioedema (HAE) is a rare autosomal dominant
disorder characterized by recurrent episodes of painful (and
usually asymmetric) swelling without urticaria that leads to
substantial morbidity and even mortality (in the case of
laryngeal involvement) if left untreated.
• Delayed diagnosis and misdiagnosis of HAE are common,
particularly during pregnancy and the postpartum period.
• Hereditary angioedema should be considered in the differential
diagnosis of any patient presenting with unexplained
abdominal pain and recurrent episodes of angioedema
(particularly if asymmetric in nature) without urticaria.
• Tests to confirm the diagnosis of HAE include measurement of
C4 and C1 inhibitor (INH) antigen and function.
• Successful pregnancy and delivery are possible in HAE with
proper medical management, which includes plasma-derived
C1-INH and collaboration with HAE specialists.

Rotavirus

What is rotavirus?

Rotavirus is a common stomach and intestinal illness. It mostly affects babies and young children. It is one of the most common causes of severe diarrhea. Almost all children will have a rotavirus infection by the time they are 5 years old.

Rotavirus is highly contagious. It spreads through direct or indirect contact with an infected person’s feces (poop). It can happen if you touch a contaminated object, food, water, or the hands or mouth of an infected person. The virus enters your body when your unclean hand touches your nose or mouth.

The risk of catching rotavirus is greatest in the winter and spring (December through June). Adults can get the disease, but their symptoms usually aren’t as severe.
