A male infant presenting with multiple anomalies including a midline cleft palate, anasarca, hepatomegaly, pulmonary edema, agenesis of the corpus collosum, and complex congential cardiac anomalies was found to have mosaicism for an additional chromosome that appeared (following GTG-banding and FISH) to be a monocentric isochromosome of the short arm of chromosome 8 (46,XY/47,XY, +i(8p)). Nine other cases of mosaicism for an additional i(8p) were reviewed. Considerable phenotypic variation was noted. Consistent features were identified including agenesis of the corpus callosum, cardiac malformations, and minor facial dysmorphology. The phenotype of these patients partially overlaps those of trisomy 8 and trisomy 8p. By studying additional individuals with this condition, mosaic tetrasomy 8p may emerge as a recognizable clinical phenotype.

Reexpansion of a collapsed lung increases the microvascular permeability and causes reexpansion pulmonary edema. Neutrophils and their products have been implicated in the development of this phenomenon. The small GTP-binding proteins Rho and its target Rho-kinase (ROCK) regulate endothelial permeability, although their roles in reexpansion pulmonary edema remain unclear. We studied the contribution of ROCK to pulmonary endothelial and epithelial permeability in a rabbit model of this disorder. Endothelial and epithelial permeability was assessed by measuring the tissue-to-plasma (T/P) and bronchoalveolar lavage (BAL) fluid-to-plasma (B/P) ratios with (125)I-labeled albumin. After intratracheal instillation of (125)I-albumin, epithelial permeability was also assessed from the plasma leak (PL) index, the ratio of (125)I-albumin in plasma/total amount of instilled (125)I-albumin. T/P, B/P, and PL index were significantly increased in the reexpanded lung. These increases were attenuated by pretreatment with Y-27632, a specific ROCK inhibitor. However, neutrophil influx, neutrophil elastase activity, and malondialdehyde concentrations in BAL fluid collected from the reexpanded lung were not changed by Y-27632. In endothelial monolayers, Y-27632 significantly attenuated the H(2)O(2)-induced increase in permeability and mitigated the morphological changes in the actin microfilament cytoskeleton of endothelial cells. These in vivo and in vitro observations suggest that the Rho/ROCK pathway contributes to the increase in alveolar barrier permeability associated with reexpansion pulmonary edema.
