The first aim of this study was to determine the prevalence of congenital toxoplasmosis in newborn infants treated by the public health system in Porto Alegre, a city in southern Brazil, using neonatal screening for Toxoplasma gondii-specific IgM. The second aim was to investigate whether the cases detected by this approach could have been identified by the prenatal screening for antibodies to T. gondii that was performed in the same population. A fluorometric assay was used to analyse T. gondii-specific IgM in filter paper specimens obtained from newborn infants for routine screening for metabolic diseases. When the specific IgM was positive, serum samples from the infant and the mother were requested for confirmatory serological testing, and the infant underwent clinical examination. Among 10 000 infants screened for T. gondii-specific IgM, seven filter paper samples were positive, and congenital toxoplasmosis was confirmed in six patients. The prevalence of IgM specific for T. gondii was 6/10 000 [95% CI 2/10 000, 13/10 000]. One infected infant had already been identified in the maternity ward before birth, three had been identified by maternal serology at delivery, and two infants with congenital toxoplasmosis were identified solely through neonatal screening. Although four mothers of the patients with congenital toxoplasmosis received prenatal care, and three mothers had one or two serological tests for T. gondii-specific antibodies (one at first trimester, one at first and second trimesters, and the other at second and third trimesters), they were not identified during pregnancy as infected. Neonatal screening identified cases of infection not detected by obtaining only one or two serum samples from pregnant women for T. gondii serology, mainly when infection was acquired and transmitted in late pregnancy. Maternal serology at delivery and neonatal screening were especially useful in the identification of infants with congenital toxoplasmosis when the mother did not receive regular prenatal serological testing or prenatal care.
Abstract:Kwashiorkor is a type of protein-energy malnutrition where diet protein deficit is found, in spite of appropriate caloric intake. Cutaneous manifestations include xerosis, with abnormally dry skin that has a flaking enamel paint aspect, a typical red to gray-white hair color, the "flag sign" and more evident edema in lower limbs and face, giving it a full moon appearance. This article reports a case of a male adult patient who had undergone Whipple surgery for treatment of chronic pancreatitis associated with pseudotumor of the pancreatic head that progressed to cutaneous manifestations of kwashiorkor after pulmonary tuberculosis. Keywords: Pancreatitis, chronic; Protein-energy malnutrition; Tuberculosis, pulmonary Resumo: Kwashiorkor é um tipo de desnutrição proteico-energética em que há deficiência dietética de proteí-na, embora a ingestão de calorias se mantenha adequada. As manifestações cutâneas incluem pele xerótica, com aspecto de esmalte descascado, típica coloração avermelhada a branco-acinzentada dos cabelos, o sinal da bandeira e edema mais evidente, nos membros inferiores e na face, dando aspecto de lua cheia. O presente artigo relata o caso de um paciente adulto, do sexo masculino, previamente submetido à duodenopancreatectomia para tratamento de pancreatite crônica associada ao pseudotumor em cabeça de pâncreas que evoluiu com alterações cutâneas de kwashiorkor após tuberculose pulmonar.
Sarcoidosis is a granulomatous disease of unknown etiology. The skin is commonly affected. Cutaneous manifestations can mimic other diseases and autoimmune disorders. The dermatologist plays a critical role in elucidating the clinical diagnosis and assisting other specialists in the investigation of a systemic disease. We report a patient with typical cutaneous manifestation of sarcoidosis with pulmonary involvement.
Relatamos um caso típico, em um paciente masculino de 20 anos, da síndrome de Sjögren-Larsson, que é uma doença neurocutânea, autossômica recessiva e incapacitante, caracterizada por ictiose congênita, plegia espástica e retardo mental. É causada pela deficiência da enzima aldeído graxo desidrogenase. Não tem cura, porém a maioria dos pacientes sobrevive até a idade adulta. O tratamento deve ser multidisciplinar e a terapia dermatológica tem o objetivo de aliviar o prurido persistente e a ictiose.
