Pulmonary Agenesis and Hypoplasia.
In recent years the more frequent use of x-rays has revealed various congenital abnormalities of the lungs which had formerly passed undetected during life, since the clinical signs and symptoms may be minimal. An attempt is made here to elucidate the different pictures which may be seen in varying degrees of underdevelopment of the lungs. For clarity of description the following nomenclature i...
متن کاملRenal Hypoplasia in a Calf
Renal hypoplasia refers to a congenitally small kidney where there is essentially normal residual parenchyma but smaller calyces, lobules, and papillae. This anomaly can be divided into two broad groups: complete (global) renal hypoplasia and segmental renal hypoplasia. In this study, a 3 days-old simmental calf was diagnosed with renal hypoplasia and unreconstructed exstrophic bladder. It pres...
متن کاملHypoplasia of medullary arcuate nucleus in unexpected late fetal death (stillborn infants): a pathologic study.
OBJECTIVES To evaluate the frequency, morphology, and pathogenesis (primary or secondary) of the abnormally developed medullary arcuate nucleus (ARCn) in stillbirths. METHODS We examined 26 stillbirths (24 antepartum, 2 intrapartum) that had a gestational age between 25 and 40 weeks and a normal karyotype. All of the stillborns were described as well-developed, with body length and weight pro...
متن کاملChorioamnionitis and Congenital Abnormalities of the Brainstem (Arcuate Nucleus and Pre-Bötzinger Complex Hypoplasia) in a Case of Late Unexplained Stillbirth
Background: Fetal death (stillbirth), that occurs every 100-200 pregnancies in industrialized countries, has not significantly decreased in recent years, mostly because of scarce research activities in this field. Fetal death is often, in up to 60-80% of cases, unexplainable, even after routine diagnostic examinations. Objectives: This work aims to stress the importance of in-depth histopatholo...
متن کاملAssociation between vertebral artery hypoplasia and posterior circulation stroke
BACKGROUND The clinical significance of vertebral artery (VA) hypoplasia is under discussion. The aim of this retrospective study is to evaluate a hypothesis of a possible causal link between VA hypoplasia (VAH) and the incidence of posterior circulation stroke (PCS) or TIA depending on the degree of VAH and vascular risk factors. METHODS A total of 367 symptomatic (PCS or TIA) and 742 asympt...
