Cranioectodermal dysplasia: a probable ciliopathy.

Cranioectodermal dysplasia (CED), also known as Sensenbrenner syndrome, is a rare autosomal recessive genetic disorder characterized by typical craniofacial, skeletal and ectodermal defects, and tubulointerstitial nephritis leading to early end-stage renal failure. We report on a new familial case of a 9-year-old patient and two fetuses of 23 and 19 weeks of gestation respectively. Hypohidrosis was an additional ectodermal finding is the patient with CED.

Genetic skeletal disorders of the fetus and infant: pathologic and molecular findings in a series of 41 cases.

Background: Genetic skeletal disorders of the fetus and infant are a large group of genetic disorders, comprising the groups formerly assigned as skeletal dysplasias (osteochondrodysplasias), dysostoses, and malformation syndromes with a skeletal component. Genetic skeletal disorders may be prenatally detected by ultrasonography or result in intrauterine or early postnatal death, constituting one difficult diagnostic field met by the pathologist who performs the perinatal autopsy.

Methods: In this retrospective study, we have gathered radiologic, physical, histopathologic, and molecular data regarding 41 cases of genetic skeletal disorders diagnosed among 1980 fetal and perinatal autopsies over a 10-year period.

Pathologic, radiographic and molecular findings in three fetuses diagnosed with HEM/Greenberg skeletal dysplasia.

Background: Greenberg skeletal dysplasia is a very rare, autosomal recessive, in utero, lethal chondrodystrophy for which only eight index cases of diverse ethnic origin have been reported so far. The defect is associated with a defect in cholesterol biosynthesis and due to mutations in the gene encoding the lamin B receptor (LBR).

Methods: A familial case of three fetuses of a consanguineous Greek couple is presented including prenatal, physical, radiographic, histopathologic, and molecular genetic findings.

Serial blood donations for intrauterine transfusions of severe hemolytic disease of the newborn with the use of recombinant erythropoietin in a pregnant woman alloimmunized with anti-Ku.

Background: The management of a pregnant woman with the rare Ko phenotype and anti-Ku is a special challenge, because matched blood is extremely rare and the possibility of severe hemolytic disease of the newborn is high.

Case Report: A 30-year-old woman with rare Ko (Knull) phenotype presented at 18 weeks of gestation with positive indirect agglutination test results. She had anti-Ku due to previous blood transfusion, one pregnancy, and two abortions.
