In a sample taken from Apipucos Reservoir (Recife, PE, Brazil) for taxonomic study, a high percentage (40%) was found of cladoceran Ilyocryptus spinifer individuals with morphological abnormalities on their postabdomen. There was not a fixed pattern of the malformations, which varied in gravity, and could affect the postanal spines or terminal claws. The postabdominal abnormalities are described and compared to the ones described in the literature. The hypothesis of the morphological abnormalities being induced by an occasional environmental toxicant is discussed.
We report a chromosomally normal infant boy with congenital diffuse cutis laxa, severe micrognathia, contractures of all limbs, and central nervous system abnormalities including agenesis of the corpus callosum, born to a woman taking D-penicillamine (DP) for Wilson disease (WD) throughout her pregnancy. His postnatal course was remarkable for chronic lung disease, profound developmental delays, and probable cortical blindness, as well as resolution of his cutis laxa. Embryopathy is a rare complication in babies born to pregnant women treated with DP, and there have been only seven previous reports of birth defects in exposed infants (three of which had favorable postnatal outcomes). The etiology of the severe outcome in this boy is unclear, but prenatal measurement of maternal copper and zinc levels may be indicated for management.
Care of pregnant women with multiple sclerosis (MS) is challenging because of the multiple physiological changes associated with pregnancy and the need to consider the impact of any intervention on the foetus. Pregnancy is associated with clinical MS stability or improvement, while the rate of relapse rises significantly during the first three months post-partum before coming back to its level prior to pregnancy. Gestational history has no influence on long-term disability and MS does not seem to influence pregnancy or the child's health. Apart from methotrexate and cyclophosphamide, most drugs used regularly to treat MS can safely be used by pregnant women. Intravenous steroids may be used with relative safety during pregnancy. Maternal use of azathioprine is not associated with an increased risk of congenital malformations, though impaired foetal immunity, intrauterine growth retardation and prematurity are occasionally observed. Cyclosporin is not teratogenic, but may be associated with growth retardation and prematurity. Pregnancy should be avoided in women treated with methotrexate because of its known abortifacient effects and risk of causing typical malformations. Cyclophosphamide is teratogenic in animals, but population studies have not conclusively demonstrated its teratogenicity in humans. Until information is available regarding safety, glatiramer acetate, mitoxantrone, interferon-beta-1a and interferon-beta-1b should be discontinued before an anticipated pregnancy. Women with MS are no more likely to experience delivery complications than are women without MS and the mode of delivery should be decided strictly on obstetrical criteria. Spinal, epidural and general anaesthesia can all be used safely in MS patients. Young women with MS who desire children can be reassured that their infants are not at increased risk of malformations, preterm delivery, low birth weight, or infant death. The progressive nature of the disease may motivate affected women to start or complete their families as soon as possible.
