Insights

Infantile hypertrophic pyloric stenosis (IHPS) is linked to male sex, maternal smoking, and bottle-feeding. Further prospective studies are needed to confirm these perinatal risk factors for IHPS.

Area of Science:

  • Pediatric Surgery
  • Neonatal Research
  • Epidemiology

Background:

  • Infantile hypertrophic pyloric stenosis (IHPS) is a common pediatric surgical condition.
  • While diagnosis and treatment are established, perinatal risk factors require further investigation.

Approach:

  • Systematic review and meta-analysis of case-control and cohort studies.
  • Searched Cochrane, Google Scholar, PubMed, and Scopus databases.
  • Assessed study quality using the Newcastle-Ottawa Scale (NOS).

Key Points:

  • Significant associations found between IHPS and male sex, maternal smoking, bottle-feeding, firstborn status, African ethnicity, and cesarean section.
  • No significant associations identified with multiple gestations, preterm labor, summer birth, or small for gestational age (SGA).

Conclusions:

  • Male sex, bottle feeding, maternal smoking, and African ethnicity are significantly associated with IHPS risk.
  • Most included studies were retrospective, highlighting the need for future prospective research to validate these findings.

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors

Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI)  tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining.

Peptic Ulcer Disease I: Introduction

Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...

Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Pathophysiology of Peptic Ulcer Disease: Injurious Factors01:22

Pathophysiology of Peptic Ulcer Disease: Injurious Factors

Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...
