Nutritional implications of chronic dyspepsia in childhood.

Chronic dyspepsia is common in children. However, the association of individual predominant symptoms with gastric emptying and their impact on nutritional status are poorly defined. We therefore studied 31 children (mean age 11 years, 14 boys) with chronic dyspepsia and classified their predominant symptoms (PS) by their character and severity. Gastric emptying (GE) T(1/2) of a solid meal was carried out in all patients, while upper gastrointestinal endoscopy was done in the treatment failures. All patients received two months treatment with cisapride. Weight for age z scores were recorded before and three months after treatment. There were 12 patients with epigastric pain (EP) as the PS (7 moderate/severe). Postprandial fullness (PF) was the PS in 19 patients (12 moderate/severe). GE T(1/2) was prolonged and weight for age z scores were lower in children who had moderate/severe (but not mild) PF comparing to those who had EP (P < 0.0001 and P = 0.003, respectively). A significant improvement in weight was observed in the same group alone following treatment with cisapride (P = 0.0003). In conclusion, impaired GE is common in dyspeptic children with PF and have adverse effects on nutritional status.

Rectal prolapse in pediatrics.

Rectal prolapse in pediatrics has its highest incidence in infancy and is uncommonly seen in industrialized countries. The prolapse may involve only the mucosa (mucosal prolapse) or all layers of the rectum (complete prolapse or procidentia). It is usually detected by the child's parents and is brought urgently to medical attention; however, it is usually spontaneously reduced by the time they reach the practitioner's office. Rectal prolapse should be viewed as a symptom of an underlying condition rather than a discrete disease entity. Potential causes are increased intraabdominal pressure, diarrheal and neoplastic diseases, malnutrition, and conditions predisposing to pelvic floor weakness. Its strong association with cystic fibrosis makes the sweat test mandatory for infants and children with recurrent rectal prolapse. Of particular importance are three entities related to rectal prolapse that may easily escape diagnosis by practitioner: occult rectal prolapse, solitary ulcer of the rectum syndrome, and inflammatory cloacogenic polyps. The treatment of rectal prolapse is mainly conservative and is directed at the underlying conditions. Surgical intervention may be required for recurrent rectal prolapse refractory to conservative measures. The simplest, less invasive, yet highly effective approach, appears to be perirectal injection with a sclerosing agent. While the majority of children experience spontaneous resolution of the prolapse, the prognosis is worse when presentation occurs after the age of 4 years.
