1/5. Multiple congenital malformations including generalized hypertrichosis with gum hypertrophy in a child exposed to valproic acid in utero.Fetal valproate syndrome results from in utero exposure to valproic acid. It is characterized by a distinctive facial appearence, a cluster of minor and major anomalies, and central nervous system dysfunction. We report on a child exposed prenatally to valproic acid with unusual anomalies. This patient was the first child of young parents. Mother had several generalized seizures one year before this pregnancy, and since than she took valproic acid. pregnancy was otherwise uneventful. At birth physical examination showed generalized hypertrichosis sparing palms and soles, coarse face, gum hypertrophy, hypotonia, club feet and club hands, two annular constrictions of the right lower leg, and abnormal dermatoglyphics. Skeletal x-rays were normal. Gum hypertrophy and hypertrichosis may be part of a broader pattern of altered morphogenesis in fetus exposed to valproic acid or this patient had two conditions, fetal valproate syndrome and hypertrichosis with gum fibromatosis.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/5. Neonatal toxicity and transient neurodevelopmental deficits following prenatal exposure to lithium: Another clinical report and a review of the literature.I report the case of an infant girl who was exposed to lithium during gestation and her follow-up at the age of 1 year. She presented with transient neurodevelopmental deficits including lethargy, hypotonia, and poor oral feeding ability in the neonatal period. She required supportive treatment and made gradual improvement in neurologic functioning. On examination at the age of 1 year, physical findings and psychomotor development were normal. The English literature from 1978 to 2004 is reviewed. A total of 30 patients who were exposed to lithium during gestation with adequate clinical description were identified. A significant number of these babies presented with neurodevelopmental deficits and depressed neurological status including hypotonia, respiratory distress syndrome, cyanosis, lethargy, and weak suck and Moro reflexes in the neonatal period. The majority of these abnormalities resolved and most babies made full recovery. Other abnormalities were structural as well as functional involvement of the cardiovascular system, macrosomia, prematurity, jaundice, diabetes insipidus, and involvement of the thyroid gland. While the use of lithium during pregnancy does not appear to significantly increase the risk of congenital anomalies, it is frequently associated with perinatal complications and reversible neonatal toxicity. Suggested guidelines for appropriate monitoring of infants and breast-feeding of exposed babies are presented. In addition, prenatal surveillance of women with bipolar disorders who are being treated with lithium is briefly discussed.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/5. Developmental language disability as a consequence of prenatal exposure to ethanol.Two pre-school-aged patients with a history of prenatal exposure to ethanol had abnormal head size and developmental delay. Both children were strikingly similar in physical appearance, behavior, and cognitive dysfunction. Facial features were typical of fetal alcohol syndrome. head circumference greater than 97th percentile without hydrocephalus and no evidence of prenatal or postnatal growth failure were unusual for ethanol teratogenicity. Each child had a similar pattern of verbal and behavioral dysfunctions characterized by (1) marked hypervigilence, (2) distractability, and (3) cognitive confusion manifested as anxiety and behavioral disorganization. It is suggested that a history of prenatal exposure to ethanol associated with (1) large head circumference, (2) facial features of fetal alcohol syndrome, and (3) early developmental delay, particularly in language acquisition, and impaired modulation of attention and arousal may represent a possible new effect of alcohol teratogenicity.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
4/5. Vestibular dysfunction in a child with embryonic exposure to accutane.Children with a history of embryonic exposure to Accutane (isotretinoin) are at great risk for major physical malformations, brain malformations, and decreased intelligence. A case is presented of a 4-year 7-month-old black male with a history of embryonic exposure to Accutane who was born with embryopathy that includes bilateral major ear deformities. The child has a significant bilateral conductive hearing loss, and, in addition, a left sided sensorineural loss. Vestibular function testing revealed evidence of peripheral and central vestibular dysfunction. A course of diphenhydramine hydrochloride and Donnatal (phenobarbital, hyoscyamine sulfate, atropine sulfate, and scopolamine hydrobromide) significantly alleviated the symptoms of vestibular dysfunction. Otologic management of these children should include clinical documentation of the external deformities, evaluation of cochlear function, and early auditory habilitation. Vestibular function should also be evaluated in all children with a history of embryonic exposure to isotretinoin.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/5. methylene blue-induced phototoxicity: an unrecognized complication.OBJECTIVE. To describe photosensitization after prenatal exposure to a toxic amount of methylene blue and to alert pediatricians that, in a review of the literature, photosensitization (which this dye is capable of) has not been reported as a complication of prenatal exposure. DESIGN AND patients. A descriptive report of physical findings and significant laboratory tests in a very low birth weight preterm infant with prenatal exposure to methylene blue and a comparison of this reported case with previously described patients' complications and treatment. SETTING. Neonatal intensive care unit. INTERVENTION. Monitoring of laboratory tests to assess for methylene blue toxicity: two exchange transfusions for methemoglobinemia, hemolytic anemia, and hyperbilirubinemia; phototherapy for hyperbilirubinemia; and pathologic examination of skin bullae. RESULTS. Within hours of exposure to phototherapy, redness developed on all exposed areas of the patient's skin (which was initially deep blue), followed by bullae and desquamation of about 35% of the total skin surface area. The desquamation of erythematous areas continued even after discontinuation of phototherapy. Complete re-epithelialization was attained by 3 weeks of age. In addition to this newly observed complication, the patient had other previously described toxic effects. CONCLUSION. We have reported a previously unrecognized complication associated with high prenatal exposure to methylene blue and treatment with phototherapy. methylene blue phototoxicity may be related to the high prenatal dose of the dye relative to patient's small size and young gestational age.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
