No evidence of vertical transmission of HTLV-I in bottle-fed children

The most frequent pathway of vertical transmission of HTLV-I is breast-feeding, however bottle fed children may also become infected in a frequency varying from 4 to 14%. In these children the most probable routes of infection are transplacental or contamination in the birth canal. Forty-one bottle-fed children of HTLV-I seropositive mothers in ages varying from three to 39 months (average age of 11 months) were submitted to nested polymerase chain reaction analysis (pol and tax genes). 81.5% of the children were born by an elective cesarean section. No case of infection was detected. The absence of HTLV-I infection in these cases indicates that transmission by transplacental route may be very infrequent.

Avaliação das necessidades educacionais dos cuidadores de pessoas com esquizofrenia: contribuição para a validação de um questionário

RESUMO: Os programas psicoeducacionais para cuidadores de pessoas com esquizofrenia são muitas vezes construídos sem terem em conta as necessidades educacionais destes utilizadores dos serviços de saúde mental. Apresenta-se uma revisão da literatura sobre esquizofrenia, família, intervenções familiares e avaliação de necessidades educacionais. Conduziu-se um estudo transversal descritivo com características exploratórias numa amostra de conveniência de principais cuidadores (N=74) de pessoas com esquizofrenia em tratamento no Departamento de Psiquiatria e Saúde Mental do Hospital de S. Francisco Xavier. A metodologia utilizada é do tipo qualitativo e quantitativo. Objectivos: Descrever as características de uma amostra de principais cuidadores de pessoas com esquizofrenia e as suas necessidades educacionais, bem como contribuir para a validação do Educational Needs Questionnaire (ENQ). Instrumentos: Educational Needs Questionnaire (ENQ) e Inventário Sócio-Demográfico para Familiares (RSDS). Resultados: O doente com esquizofrenia é cuidado sobretudo pela família, sendo as mães os cuidadores por excelência. Trata-se de mulheres idosas que cuidam do doente há muitos anos e que necessitam saber mais sobre como obter ajuda dos serviços de saúde mental. Conclusões: Os cuidadores sentem que os serviços de saúde mental não lhes dão o apoio de que necessitam e estão preocupados sobretudo com o estigma e com o que acontecerá aos seus doentes após a sua morte. A versão portuguesa do ENQ mostrou possuir boa fiabilidade, recomendando-se o desenvolvimento de estudos que dêem continuidade ao esforço de validação aqui iniciado.-------------ABSTRACT: The psychoeducational programs for caregivers of people with schizophrenia are often built without regard for the educational needs of users of mental health services. We present a review of the literature on schizophrenia, family, family interventions and evaluation of educational needs. We conducted a cross-sectional study with exploratory characteristics in a convenience sample of primary caregivers (N = 74) of people with schizophrenia being treated in the Department of Psychiatry and Mental Health at the Hospital of St. Francisco Xavier. We used a qualitative and quantitative methodology. Objectives: To describe the characteristics of a sample of primary caregivers of people with schizophrenia and their educational needs, as well as contribute to the validation of the Educational Needs Questionnaire (ENQ). Instruments: Educational Needs Questionnaire (ENQ) and Inventário Sócio-Demográfico para Familiares (RSDS). Results: Patients with schizophrenia are cared by the family, mothers are the caregivers for excellence. They are older women who take care of the patient for many years and they need to know more about how to get help from mental health services. Conclusions: Caregivers feel that mental health services don‟t give them the support they need and they are especially worried about the stigma and what will happens to their patients after their death. The Portuguese version of the ENQ proved to have good reliability and we recommend the development of studies that give continuity to the validation effort here started.

Mental health promotion during pregnancy and early childhood : an action- research project in primary health care

ABSTRACT – Background: Primary Health Care (PHC) is usually the first contact with the health system, and health professionals are key mediators for enabling citizens to take care of their health. In Portugal, great improvements have been achieved in the biometric indicators of maternal and child health during the last decades. Nevertheless, scant attention has been paid to the mental health dimension, in spite of the recognition of its importance, being pregnancy and early childhood crucial opportunities in the lifecycle for mental health promotion, especially in the early years of life, with a strong impact in the health of the child. The impact of early attachment between mother and baby on maternal and child health has long been recognized. This attachment can be influenced by some factors, as the mother’s emotional adjustment. Attention to these factors may facilitate implementation of both positive conditions and preventative measures. Family support during the transition to parenthood has been highlighted as an effective measure and PHC professionals are in a privileged position as information sources as well as mediators. Aims: The project we present describes an action-research process developed together among academic researchers and health professionals to embrace these issues. We intend to enable health professionals to support families in the transition to parenthood thereby promoting children’s mental health. Approach: The project is driven by a participatory approach intended to lead to reorganization of health care during pregnancy and early childhood. Effective change happens when those involved are interested and motivated, what makes their participation so important. Reflection about current practices and needs, and knowledge about evidence-based interventions have been guiding the selection of changes to introduce in clinical practice for family support and development of parenthood skills and self-confidence. Development: We summarize the main steps in development: the initial assessment and the picture taken from the community under study; the decision making process; the training programme of PHC professionals in action; the review of the protocols of maternal consultation, home visits and antenatal education; the implementation planning; the plan for evaluation the effectiveness of the changes introduced in the delivery of maternal and child health care units. The already developed work has shown that motivation, leadership and organizational issues are decisive for process development.-------------------------- RESUMO - Os Cuidados de Saúde Primários são habitualmente o primeiro contacto com o sistema de saúde e os profissionais de saúde são mediadores chave na capacitação dos cidadãos para cuidarem da sua saúde. Em Portugal, nas últimas décadas, têm-se alcançado grandes melhorias nos indicadores biométricos de saúde materno-infantil. Contudo, tem-se dedicado pouca atenção à dimensão de saúde mental, apesar do reconhecimento da sua importância. A gravidez e primeira infância têm sido apontadas como uma oportunidade crucial no ciclo de vida para a promoção da saúde mental. É dado especial enfoque aos primeiros tempos de vida, dado o forte impacto na saúde da criança. O impacte da vinculação precoce entre a mãe e o bebé na saúde da mãe e da criança há muito que é reconhecido. Esta vinculação pode ser influenciada por vários factores, nomeadamente pelo ajustamento emocional da mãe. A focalização nestes aspectos pode facilitar a criação de condições favoráveis e a implementação de medidas preventivas. O suporte familiar durante o período de transição para a parentalidade tem sido enfatizado como uma medida eficaz e os Cuidados de Saúde Primários estão numa posição privilegiada como fontes de informação e como mediadores. O projecto que apresentamos descreve um processo de investigação- acção desenvolvido em parceria entre investigadores académicos e profissionais de saúde para abordar os aspectos referidos. Pretende-se capacitar os profissionais de saúde para apoiarem as famílias na transição para a parentalidade, promovendo assim a saúde mental das crianças. O projecto baseia-se numa abordagem participativa, direccionada para a reorganização dos cuidados durante a gravidez e primeiros tempos de vida. A mudança efectiva acontece quando os envolvidos estão interessados e motivados, o que torna a sua participação tão importante. A reflexão acerca das práticas e necessidades actuais e o conhecimento acerca de intervenções baseadas na evidência têm guiado a selecção das alterações a introduzir na prática clínica, no sentido de promover o suporte familiar e o desenvolvimento de competências parentais e auto-confiança. Neste artigo, apresentamos as etapas principais do desenvolvimento do projecto: avaliação inicial da comunidade em estudo; processo de tomada de decisão; programa de formação dos profissionais dos Cuidados de Saúde Primários; revisão dos protocolos da consulta de saúde materna, visita domiciliária e educação pré-natal; planeamento da implementação; plano de avaliação da efectividade das alterações introduzidas na prestação de cuidados. O trabalho já desenvolvido tem mostrado que a motivação, liderança e aspectos

No encontro comigo e com os outros

No presente Relatório apresenta-se o Projeto “No Encontro Comigo e Com os Outros”, desenvolvido com um grupo de mães de pessoas com deficiência intelectual. Este Projeto propõe uma resposta de apoio e de partilha num grupo de mães, visando o estabelecimento de relações em grupo, para que se reflita de forma autónoma nos problemas comuns. Desta forma, este Projeto, para além de propor encontros de apoio emocional, aponta para o envolvimento das mães nas atividades institucionais da Associação que os filhos frequentam. Os desafios colocados às famílias com filhos com deficiência fundamentaram o desenvolvimento de um Projeto em Educação e Intervenção Social, enquanto promotor de reflexão e de autonomia. Neste sentido, todo o Projeto posicionou-se, metodologicamente, na Investigação Ação-Participativa, onde, com as pessoas, se recolheu e analisou toda a informação que conduzia aos problemas e necessidades evidenciados. A finalidade deste projeto, e todos os objetivos propostos, foram, assim, ao encontro dos problemas e necessidades priorizados pelos intervenientes, propondo-se, a partir de um conjunto de ações, alcançar uma nova realidade. Desta forma, os resultados obtidos com o Projeto foram satisfatórios, por ter contribuído para o estabelecimento de laços entre as mães, por ter fomentando a partilha e a reflexão acerca dos problemas vivenciados e por ter envolvido as mesmas nos processos institucionais. Deficiência, Família, Grupo de Apoio, Partilha, Relação.

Toxoplasma-IgM and IgG-avidity in single samples from areas with a high infection rate can determine the risk of mother-to-child transmission

Anti-Toxoplasma IgG-avidity was determined in 168 serum samples from IgG- and IgM-positive pregnant women at various times during pregnancy, in order to evaluate the predictive value for risk of mother-to-child transmission in a single sample, taking the limitations of conventional serology into account. The neonatal IgM was considered the serologic marker of transmission. Fluorometric tests for IgG, IgM (immunocapture) and IgG-avidity were performed. Fifty-one of the 128 pregnant women tested gave birth in the hospital and neonatal IgM was obtained. The results showed 32 (62.75%) pregnant women having high avidity, IgM indexes between 0.6 and 2.4, and no infected newborn. Nineteen (37.25%) had low or inconclusive avidity, IgM indexes between 0.6 and 11.9, and five infected newborns and one stillbirth. In two infected newborns and the stillbirth maternal IgM indexes were low and in one infected newborn the only maternal parameter that suggested fetal risk was IgG-avidity. In the present study, IgG-avidity performed in single samples from positive IgM pregnant women helped to determine the risk of transmission at any time during pregnancy, especially when the indexes of the two tests were analysed with respect to gestational age. This model may be less expensive in developing countries where there is a high prevalence of infection than the follow-up of susceptible mothers until childbirth with monthly serology, and it creates a new perspective for the diagnosis of congenital toxoplasmosis.

Digit Ratio (2D:4D) in Newborns: Influences of Prenatal Testosterone and Maternal Environment

Introduction: The 2D:4D digit ratio is sexually-dimorphic, probably due to testosterone action through the perinatal period. We characterize the 2D:4D ratio in newborn (NB) infants, in between the pre- and postnatal surges of testosterone, and relate it to the mother's 2D:4D and to testosterone levels in the amniotic fluid (AF). Subjects and methods: Testosterone was assayed in samples of maternal plasma and AF collected at amniocentesis. Shortly after birth, 106 NBs and their mothers were measured for 2D:4D ratio. Results: NB males had lower mean 2D:4D ratios than females but this dimorphism was significant only for the left hand (males: 0.927; females: 0.950; p=0.004). Mothers who had sons had lower 2D:4D ratios than those who had daughters and the mother's 2D:4D were higher than those of NBs regardless of sex. Both hands of NB females were negatively correlated with AF testosterone and positively correlated with the mother's 2D:4D, but males showed no significant associations. Maternal plasma testosterone also showed a negative weak correlation with NB's digit ratio in both sexes. Conclusions: Sexual dimorphism at birth was only significant for the left hand, in contrast with reports of greater right hand dimorphism, suggesting that postnatal testosterone is determinant for 2D:4D stabilization. The lower 2D:4D ratios in mothers who had sons support claims that hormone levels in parents are influential for determining their children's sex. NB female's digit ratio, but not males', was associated to the level of AF testosterone. The mother's 2D:4D ratios were positively correlated with their daughters' 2D:4D, but the same was not observed for male NBs, suggesting that prenatal testosterone levels in male fetus lead their 2D:4D ratios to stray from their mothers' with high individual variability.

Classic and molecular study of Giardia duodenalis in children from a daycare center in the region of Presidente Prudente, São Paulo, Brazil

Epidemiological studies on giardiasis by using molecular techniques such as RAPD (Randomly Amplified Polymorphic DNA) may give information on factors related to the transmission of Giardia duodenalis. The aim of this work was to assess the epidemiology of G. duodenalis in 101 children attended at a daycare center in Presidente Bernardes, SP, Brazil. After parasitological examinations in feces samples, 15 children presented cysts of G. duodenalis. Their respective parents, brothers and pets, besides the daycare center workers, also had their feces submitted to parasitological analysis. Seven mothers and nine brothers also presented G. duodenalis cysts, while fathers, daycare workers and pets (dogs) did not presented the parasite. Besides the 15 cases with G. duodenalis, other 23 children presented other enteroparasites (Entamoeba coli, Endolimax nana, Enterobius vermicularis, Ascaris lumbricoides and Trichuris trichiura). Samples of G. duodenalis cysts from children and their relatives were submitted to molecular typing by RAPD after genomic DNA extraction and amplification of a fragment of the 18S rDNA region by PCR. After examining 31 isolates of G. duodenalis (children and their respective mothers and brothers), it was concluded that the parasite transmission occurred in children, probably during daily cohabitation at the daycare center, but not at home among their relatives or pets.

A Brother or a Sister With CP. How Much it Makes a Difference in Childhood and Adulthood?

Every month we see to be published dozens of scientific papers about etiology and physiopathology of CP, imaging, treatment, survival, quality of life of patients and of mothers (just a few) and so on. Papers dealing with the feelings and the problems of siblings of children and adults with CP in the most important scientific journals are extremely rare. However in internet we can find the sites of the most important Cerebral Palsy Societies, like the British, the Australian and the American ones already devoting a special attention to the issue of siblings; we also can see several interesting blogs of parents sharing their experiences not only with the handicapped child but also with the siblings, even counseling some books written for children giving practical advices how to deal and live with a handicapped sibling. What was a surprise to me were the several sites of adults having a disabled sibling, frequently with CP, in a new situation: without parents to care them.

Perinatal Bacterial Infection: Screenning of Vertical Transmitted Infections

Perinatal bacterial infection may be caused by any microorganism colonizing the vaginal tract. Neonatologists and paediatricians are especially concerned about group B Stretpococcus (GBS). However, Enterobactereacea, mainly E.coli and Proteus, are also responsible for infection. GBS screening may be accomplished in over 90% of pregnant women. In our maternity in 2007-2008, 85% of the mothers had been screened. Screening and prophylaxis were responsible for a decreasing incidence of neonatal infection - from 0.6/1000 to 0.15/1000 live births in Portugal, from 2002 to 2007. However there are some difficulties related to screening. In the second Portuguese study 16/57 NB with early-onset infection (28%) were born to “negative” mothers. Several factors illustrate how difficult is to draw national screening policies: a wide range of carrier’s state rate throughout a country - in Portugal from 12% to 30%. The success of any screening policy may also be affected by additional technical and organizational problems. In countries where home delivery is a tradition or a trend intrapartum GBS prophylaxis requires a very well organized assistance.. Moreover factors usually accepted as protective are not so effective. In the Portuguese study 24/57 infected newborns (42%) were delivery by caesarean section. Another subject deals with the workload in the postnatal ward generated by deficient compliance to the guidelines a problem not confirm by a study of our group. Decreasing the importance of GBS, highlight the importance of E. coli in perinatal infection. From the 16 340 registrations of the National Registry 1676 were newborns with mother-related infection. Applying the same reasoning to E.coli as to GBS and Listeria monocytogenes – that is considering all of them are of maternal origin - 6.7% of these infections were due to E. coli, 4.6% to SGB and 0.5% to Listeria monocytogenes. In conclusion screening and prophylaxis may be not the best way to prevent all GBS neonatal infections but by now it is the only available procedure. The other bacteria continue to demand a high suspicion level and immediate intervention.

Rapid HIV diagnostic test in undocumented pregnant women applied at an inner-city teaching hospital

A significant number of Brazilian gestational-age women are still not tested for HIV, representing a high risk of transmission to their newborns. The current study sought to identify the number of pregnant women with no previous testing or undocumented for HIV referred to the Gynecology and Obstetrics Department of a Regional Teaching Hospital and included diagnosis of HIV infection determined by a rapid test and perinatal transmission in pregnancy. Medical records of all pregnant women admitted to hospital from January 2001 to December 2005 were reviewed. Pregnant women without HIV results were submitted to a rapid HIV test. Those who tested positive were further tested by ELISA and confirmed by indirect immunofluorescence assay (IIA) or Western blot (WB). The viral load from babies born to HIV-infected mothers was assessed by bDNA. Of the 16,424 pregnant women analyzed (6.6%), 1,089 were undocumented for HIV. Eleven women were positive in rapid testing and 10 were confirmed by ELISA, IIA or WB, with 0.9% seropositivity. Mother/infant pairs received zidovudine monotherapy prophylaxis and infant viral load was lower than 50 copies/mL. A higher number of pregnant women previously tested for HIV during antenatal care was verified, compared to that obtained nationwide.

Characterization of a Hepatitis B virus strain in southwestern Paraná, Brazil, presenting mutations previously associated with anti-HBs Resistance

The present study investigated if hepatitis B virus (HBV) mutants circulate in the southwestern region of the State of Paraná, Brazil, by analyzing samples from children who received immunoprophylaxis but were born to HBV carrier mothers. Samples from 25 children were screened for HBV serum markers and for HBV DNA by PCR. Only one sample was positive for HBsAg, anti-HBs and HBV DNA, although the child had been vaccinated. Analysis of the S gene sequence of this sample showed the presence of a proline at position 105, a serine at position 114, three threonines at positions 115, 116 and 140, and a glutamine at position 129. The presence of these amino acids, except for serine at position 114, has been related to monoclonal or polyclonal therapy with anti-HBs after liver transplantation, whereas the presence of threonine at position 116 has been described in immunized children from Singapore. This finding demonstrates the possible circulation of HBV strains resistant to hepatitis B immunoprophylaxis in southwestern Paraná, Brazil. The genotype of the sample was identified as genotype D, which is frequently found in the region studied. Since 36% of the children had received incomplete or no immunoprophylaxis, more extensive follow-up of children born to HBsAg-positive mothers is needed.

Transmissão do vírus citomegálico através do aleitamento materno em prematuros

RESUMO: Nas últimas quatro décadas, desenvolveram-se vários estudos, dispersos por todo o mundo, visando analisar a importância da transmissão perinatal do CMV pelo leite materno, nos recém-nascidos prematuros e de baixo peso à nascença. Comparando estes estudos, as taxas de incidência de infecção e doença são extremamente variáveis, não havendo consenso entre os autores. Surgiu, assim, a necessidade de realizar a presente dissertação, pioneira ao nível nacional, com o objectivo de determinar a incidência da infecção perinatal citomegálica, transmitida através do aleitamento materno a recémnascidos prematuros, e identificar as suas consequências clínicas. Para a elaboração deste trabalho foram seleccionados todos os recém-nascidos com idade gestacional inferior a 35 semanas e respectivas mães seropositivas para CMV, internados na Unidade de Cuidados Intensivos de Neonatalogia do Hospital de São Francisco Xavier, entre o período de 1 de Outubro de 2010 e 31 Julho de 2011. Foram analisadas as urinas dos recém-nascidos e o leite materno das mães na primeira, sexta e décima segunda semana pós-parto, utilizando a técnica de Nested-PCR e, posteriormente, a PCR em Tempo Real, para determinar a carga viral do leite materno. Constatou-se que a aquisição da infecção perinatal de CMV no recém-nascido prematuro ocorre com alguma frequência (40,5%), sendo muito provável que a via de transmissão em 38,1% destes casos seja o leite materno infectado, não devendo esta ser desvalorizada. Relativamente às consequências clínicas, não foram observadas alterações clínico-laboratoriais associadas à infecção citomegálica. Analisando os factores que condicionam a transmissão da infecção citomegálica perinatal, estabeleceu-se uma correlação entre a carga viral do leite materno e a transmissão do vírus, permitindo deduzir que quanto maior a carga viral, maior o risco de transmissão. Finalmente, os resultados obtidos sugerem que o risco de transmissão da infecção e suas consequências clínicas não justificam a contra-indicação da amamentação, pois esta comporta, também, elevados benefícios. ----------------ABSTRACT: In the last four decades, several studies were developed all over the world to analyze the importance of CMV perinatal transmission through mother´s milk in the preterm and low birthweight newborns. Comparing these studies, the infection and disease incidence rates are extremely variable, without agreement between the authors. The aim of this study, the first of the kind made in Portugal, is to define the rate of perinatal cytomegalovirus infection in preterm newborns via breastfeeding and its clinical consequences. All the newborns with gestational age below 35 weeks and their CMV seropositive mothers, admitted between the October 1, 2010 and July 31, 2011 in the Neonatology Intensive Care Unit of the São Francisco Xavier Hospital, were included in this study. Human breast milk and urine specimens were collected from mothers and their preterms infants around the 1st, 6th and 12th week after delivery and analyzed by Nested-PCR. The PCR in Real Time was used to determine the breast milk viral load. It was found that the CMV perinatal infection in preterm infants occurs in 40,5% of the cases and most likely 38,1% of these were infected via breastmilk and therefore this should not be overlooked. Considering the clinical consequences, no clinical and laboratory changes associated with cytomegalovirus infection were observed. Analyzing the factors that determine the perinatal transmission of the cytomegalovirus, it was established a correlation between breast milk viral load and viral transmission, allowing to conclude that the higher the viral load the greater the risk of transmission. Finally, the obtained results suggest that the risk of CMV infection and its clinical consequences don´t justify the breastfeeding contraindication because it also provides high benefits.

HIV-1-mother-to-child transmission and associated characteristics in a public maternity unit in Presidente Prudente, Brazil

In children, vertical transmission is the main form of HIV infection. Our aim was to determine the prevalence of HIV-1 vertical transmission in mother-infant pairs in a public maternity ward in Presidente Prudente, SP. Additionally; we sought to identify characteristics associated with this form of transmission. The files of 86 HIV-1-infected mothers and their newborns referred to a Public Hospital from March 2002 to March 2007 were analyzed. The HIV-1-RNA viral load of the newborns was determined by bDNA. The HIV-1 vertical-transmission rate was 4.6%. Children that were born in the pre-term period and breastfed were at a higher risk of HIV-1 infection (p = 0.005 and p = 0.017 respectively) than children born at term and not breastfed. Prophylactic therapy with zidovudine after birth for newborns was associated with a lower risk of infection (p = 0.003). The number of newborns weighing < 2,500 g was significantly higher for infected children (p = 0.008) than for non-infected newborns. About 22.9% of mothers did not know the HIV-1 status of their newborns eight months after delivery. The study suggests that it is necessary to increase the identification of HIV-1 infection in pregnant women and their newborns as well as to offer and explain the benefits of ARV prophylaxis.

Aleitamento Materno e Infecção ou da Importância do mesmo na sua Prevenção

O leite materno tem propriedades que o tornam único e inimitável. Sob o ponto de vista de prevenção da infecção,o leite de uma mãe é, na generalidade dos casos, o alimento de eleição para o seu filho. É certo que há situações infecciosas que contra indicam o aleitamento materno mas elas são, hoje em dia, bem definidas e limitadas. Por outro lado, os conhecimentos actuais sobre as vantagens do aleitamento materno são tão baseados na ciência e na evidência, que se pode considerar um falhanço dos serviços de saúde ter uma criança não amamentada. Aceitamos que toda a mãe tem o direito de dizer não, mas só se esse, for um “não” esclarecido. O leite materno é um simbiótico, uma fonte natural de lactobacilos e bífidobactérias (pró-bióticos) e uma fonte natural de oligossacáridos (pré-bióticos) que, só por si e independentemente de todas as outras substâncias que o compõem, constituem uma protecção contra doenças infecciosas e não infecciosas em todos os períodos da vida nomeadamente na idade adulta. O recém-nascido pré-termo beneficiará muito se for alimentado com leite materno pelas condições que envolvem o seu nascimento e primeiros tempos de vida mas, muitas vezes, esse beneficio não é utilizado, tendo frequentemente como justificação precisamente esses condicionalismos.

Severe Megaloblastic Anaemia in an Infant

Vitamin B 12 or cobalamin deficiency, a rare clinical entity in pediatric age, is found most exclusively in breastfed infants, whose mothers are strictly vegetarian non-supplemented or with pernicious anaemia. In this article, the authors describe a 10-month-old infant admitted for vomiting, refusal to eat and prostration. The infant was exclusively breastfed and diffi culties in introduction of new foods were reported. Failure to thrive since 5 months of age was also noticed. Laboratory evaluation revealed severe normocytic normochromic anaemia and cobalamin defi cit. A diagnosis of α-thalassemia trait was also made. Maternal investigation showed autoimmune pernicious anaemia. This case shows the severity of vitamin B 12 deficiency and the importance of adopting adequate and precocious measures in order to prevent potentially irreversible neurologic damage.
