Pityriasis Lichenoides, Atypical Pityriasis Lichenoides, and Related Conditions: A Study of 66 Cases.

Pityriasis lichenoides (PLs) is an uncommon skin disease of unknown etiology. In recent years, an atypical form of PL has been described, showing overlapping features with mycosis fungoides (MF) and lymphomatoid papulosis. We studied 66 patients with an initial histopathologic diagnosis of PL (M:F=34:32; median age, 25 y; range, 7 to 85 y).

Fetal Cardiac Impairment in Nitrofen-Induced Congenital Diaphragmatic Hernia: Postmortem Microcomputed Tomography Imaging Study.

Introduction: We assessed the post-mortem micro-CT utility to evaluate fetal cardiac impairment in nitrofen-induced congenital diaphragmatic hernia (CDH).

Methods: At 9.5d postconception (dpc), pregnant rats were exposed to nitrofen.

Cardiac Adaptation to Severe Congenital Diaphragmatic Hernia.

Objective: Prenatal heart adaptations to congenital diaphragmatic hernia (CDH) could help define postnatal outcome.

Methods: We retrospectively analyzed post-mortem tissues from fetuses with severe CDH (n = 7). Histology and immunohistochemical distribution of desmin, muscle actin [HHF35], endothelin-1 [ET-1] and TGF-β were evaluated.
