1/54. prenatal diagnosis of congenital varicella syndrome and detection of varicella-zoster virus in the fetus: a case report.Varicella syndrome (VS) specific malformations were sonographically seen at 22 weeks and 3 days of gestation. Fetal infection was demonstrated by detection of varicella-zoster virus (VZV) dna in fetal blood and amniotic fluid by polymerase chain reaction (PCR). Following therapeutic abortion, fetal infection was confirmed by detection of VZV dna in several fetal tissues and placenta, and by histopathological findings like miliary calcified necroses in fetal organs.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
2/54. Transmission of varicella to a gravida via close contacts immunized with varicella-zoster vaccine. A case report.BACKGROUND: Varicella-zoster is a highly contagious dna virus, transmitted by direct contact and respiratory droplets. An attenuated live-virus vaccine has recently become available and is of value for susceptible, nonimmunized people. As with other attenuated vaccines, such as measles, mumps and rubella virus, there is no evidence of transmission by those immunized, and it is generally recognized that these vaccines can be given to the close contacts of pregnant women. CASE: A 32-year-old woman at 39 weeks of gestation presented with generalized pruritic vesicles and pustules. Diagnosis of primary varicella infection was made and confirmed by serologic studies. The patient denied recent or past exposure. The only significant history that the patient could recall was her exposure to her two children, who were vaccinated with the varicella-zoster vaccine eight days prior to her admission but were asymptomatic. CONCLUSION: This is the first report of a pregnant woman contracting the primary varicella infection from exposure to close contacts vaccinated with the varicella vaccine. It may not be as safe as previously thought for seronegative gravidas to be in close contact with people vaccinated with the varicella vaccine.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
3/54. Congenital varicella syndrome in the absence of cutaneous lesions.A case of congenital varicella syndrome characterized by intrauterine growth retardation, ocular and neurologic abnormalities, but no cutaneous lesions is reported. This case highlights the risk of embryopathy from varicella infection during pregnancy in non-immune women.- - - - - - - - - - ranking = 1.2935668694983keywords = pregnancy (Clic here for more details about this article) |
4/54. nitric oxide in the treatment of fulminant pulmonary failure in a young pregnant woman with varicella pneumonia.extracorporeal membrane oxygenation is the recommended treatment for fulminant pulmonary failure due to varicella pneumonia. However, in pregnancy fetal viability during extracorporeal membrane oxygenation is generally poor resulting in either therapeutic or spontaneous abortion. The present case is to our knowledge the first report on the treatment with nitric oxide to improve oxygenation in a pregnant woman with fulminant pulmonary failure due to varicella pneumonia. Adding 20 parts per million nitric oxide to the inspiratory gas increased arterial oxygen saturation from 75 to 88%, and it could be kept at this level. Due to a vaginal bleeding, an emergency Caesarean section was performed with successful outcome for the fetus. The mother started to improve after delivery and could be weaned from nitric oxide after 5 days. We conclude that inhalation of nitric oxide may be a good alternative to extracorporeal membrane oxygenation in the treatment of fulminant pulmonary failure due to varicella pneumonia in pregnancy.- - - - - - - - - - ranking = 2.5871337389966keywords = pregnancy (Clic here for more details about this article) |
5/54. Ipsilateral renal dysplasia with hypertensive heart disease in an infant with cutaneous varicella lesions: an unusual presentation of congenital varicella syndrome.A child with congenital varicella syndrome including cutaneous lesions and ipsilateral renal dysplasia with hypertensive heart disease is described. Varicella was contracted during the tenth week of gestation. Typical congenital varicella bullae, high titer of anti-varicella-zoster virus IgM, and a small right kidney were noted after birth. Hypertensive heart disease resulting from renal dysplasia occurred at 1 year of age. The cutaneous lesions and the dysplastic kidney involved the same dermatomes. nephrectomy proved to be the treatment of choice for hypertension and congestive heart failure.- - - - - - - - - - ranking = 1keywords = gestation (Clic here for more details about this article) |
6/54. Fetal varicella syndrome: disruption of neural development and persistent inflammation of non-neural tissues.Primary varicella zoster virus (VZV) infection during pregnancy is rare. If it occurs between the 8th and 20th week of gestation, fetal varicella syndrome results in 1-2% of the fetuses. We report about a varicella infection that affected a pregnant mother in the 12th week of gestation. At 33 weeks, a premature girl was born with destruction of neurons in spinal cord, spinal ganglia and plexus myentericus, and secondary developmental disturbance including mummification of one arm and segmental intestinal atresia. The brain did not show any abnormalities. However, VZV dna could be detected by PCR in tissues from the brain and spinal ganglia. Chronic necrotizing inflammation was found in the placenta, fetal membranes, and one ovary. These locations showed nuclear inclusions which by in-situ-hybridization were proven to be VZV derived. This case demonstrates that in the fetal age, 'neurotropism' of VZV signifies severe destruction but not necessarily persistent inflammation of neural tissue. However, due to the inefficient fetal immune system, inflammation can go on for weeks, preferentially in non-neural tissues.- - - - - - - - - - ranking = 3.2935668694983keywords = pregnancy, gestation (Clic here for more details about this article) |
7/54. Congenital varicella syndrome: a rare case of central nervous system involvement without dermatological features.An unusual case of congenital varicella syndrome with significant central nervous system involvement, but without dermatological features at birth is described. The mother contracted chicken pox at 15 weeks' gestation. Congenital varicella syndrome involves multiple systems, but rarely without skin lesions identifiable at birth. Although varicella infection in pregnant women is an uncommon complication, the fetal embryopathy that may result can be devastating. Antenatal diagnosis of fetal embryopathy during the first 20 weeks of pregnancy should be established by amniocentesis or cordocentesis when a mother presents in the first trimester with chicken pox, and appropriate risk counselling provided.- - - - - - - - - - ranking = 2.2935668694983keywords = pregnancy, gestation (Clic here for more details about this article) |
8/54. Fetal varicella-herpes zoster syndrome in early pregnancy: ultrasonographic and morphological correlation.We report a case of an intrauterine fetal infection by the varicella-herpes zoster virus following maternal varicella at 17 weeks' amenorrhea. prenatal diagnosis of fetal infection was confirmed by serology and fetal damage by ultrasonography. autopsy of the fetus showed multiorgan manifestation with disseminated foci of necrosis and microcalcifications, encephalitis and unilateral segmental skin scarring with an underlying hypoplastic fixed lower limb. The placenta showed a multifocal chronic villitis with multinucleated giant cells. The lesions included segmental anomalies and multiorgan damage.- - - - - - - - - - ranking = 5.1742674779932keywords = pregnancy (Clic here for more details about this article) |
9/54. Congenital varicella syndrome: case with isolated brain damage.We report a case of congenital varicella syndrome after maternal infection during the 10th week of pregnancy. None of the typical abnormalities were manifested at birth; however, the child experienced neonatal tonic convulsions that evolved to refractory focal epilepsy with adversive, complex partial, and secondarily generalized seizures. At the age of 5 years, after a prolonged generalized seizure following cranial trauma, cranial computed tomography (CT) was performed. It led to the misdiagnosis of post-traumatic intracerebral hemorrhage. Afterwards, because of persistent seizures and developmental delay with mild or slight intellectual deficit, the next CT and magnetic resonance imaging (MRI) investigation at 8 years of age disclosed massive malformation of the left cerebral hemisphere. The serologic evidence of varicella-zoster virus-specific IgG antibodies without a history of varicella disease after birth and maternal infection during early pregnancy were crucial to diagnosing the rare syndrome of congenital varicella consisting of isolated brain damage.- - - - - - - - - - ranking = 2.5871337389966keywords = pregnancy (Clic here for more details about this article) |
10/54. 1: Infections in pregnant women.Some infections are more serious in pregnant than non-pregnant women because of the potential for vertical transmission to the fetus or infant (eg, varicella, rubella, cytomegalovirus infection, toxoplasmosis and listeriosis). Pre-pregnancy or routine antenatal screening for presence of, or susceptibility to, some of these infections and appropriate management can prevent adverse fetal or perinatal outcomes; screening should include rubella IgG, hepatitis b surface antigen, serological tests for syphilis and hiv antibody. If certain other vertically transmissible infections are suspected because of a positive antenatal test result, confirmatory tests for maternal and, if indicated, fetal infection are essential before intervention is considered (eg, cytomegalovirus infection). For some vertically transmissible infections that are not readily preventable, appropriate management of maternal infection can reduce fetal damage (eg, toxoplasmosis).- - - - - - - - - - ranking = 1.2935668694983keywords = pregnancy (Clic here for more details about this article) |
