Congenital cystic adenomatoid malformation of the lung associated with esophageal atresia and tracheoesophageal fistula.

Bronchopulmonary malformations associated with esophageal atresia (EA) and tracheoesophageal fistula (TEF) are extremely rare. The authors describe a case of type II congenital cystic adenomatoid malformation (CCAM) of the right lower lobe associated with EA and TEF (Vogt-Gross type C) in a full-term female infant. The CCAM presented as an incidental radiologic finding, and a contralateral tension pneumothorax developed shortly after surgical repair of the EA. Early recognition of this rare association is essential for correct operative management.

Intrauterine volvulus without malrotation in a very low-birth-weight preterm infant.

Midgut volvulus without abnormalities of intestinal rotation/fixation is an extremely rare cause of acute intestinal obstruction in the neonatal period with a high morbidity and mortality. The authors describe an intrauterine volvulus without malrotation in a 970g preterm girl born at 27 weeks' gestation. The discrepancy between minimally evocatory clinical manifestations and severity of intestinal pathology is underscored. Resection of the necrotic bowel and primary end-to-end anastomosis within 30 hours of birth was followed by a favorable outcome. A literature review indicates a significant relation of intrauterine midgut volvulus without malrotation to preterm birth with low-birth-weight, immediate postnatal presentation and favorable prognosis.

Total and segmental colon transit time in constipated children assessed by scintigraphy with 111In-DTPA given orally.

Serial colon scintigraphy using 111In-DTPA (2 MBq) given orally was performed in 39 children referred for constipation, and the total and segmental colon transit times were measured. The bowel movements during the study were recorded and the intervals between defecations (ID) were calculated. This method proved able to identify children with normal colon morphology (no. = 32) and those with dolichocolon (no. = 7). Normal children were not included for ethical reasons and we used the normal range determined by others using x-ray methods (29 +/- 4 hours). Total and segmental colon transit times were found to be prolonged in all children with dolichocolon (TC: 113.55 +/- 41.20 hours; RC: 39.85 +/- 26.39 hours; LC: 43.05 +/- 18.30 hours; RS: 30.66 +/- 26.89 hours). In the group of children with a normal colon shape, 13 presented total and segmental colon transit times within the referred normal value (TC: 27.79 +/- 4.10 hours; RC: 9.11 +/- 2.53 hours; LC: 9.80 +/- 3.50 hours; RS: 8.88 +/- 4.09 hours) and normal bowel function (ID: 23.37 +/- 5.93 hours). In the remaining children, 5 presented prolonged retention in the rectum (RS: 53.36 +/- 29.66 hours), and 14 a prolonged transit time in all segments. A good correlation was found between the transit time and bowel function. From the point of view of radiation dosimetry, the most heavily irradiated organs were the lower large intestine and the ovaries, and the level of radiation burden depended on the colon transit time. We can conclude that the described method results safe, accurate and fully diagnostic.

Testicular microliths: their origin and structure.

Light and electron microscopic studies were done on microliths in unilateral undescended testes to determine the origin and structure. The microliths seem to originate from degenerating intratubular cells and consist of a central calcified core surrounded by concentric layers of connective fibers.
