Mutilations Due to Medical Disorders in Children

Soft-tissue and bone necrosis, although rare in childhood, occasionally occur in the course of infectious diseases, either viral or bacterial, and seem to be the result of hypoperfusion on a background of disseminated intravascular coagulation. Treatment consists in correction of septic shock and control of necrosis. Necrosis, once started, shows extraordinarily rapid evolution, leading to soft-tissue and bone destruction and resulting in anatomic, functional, psychological, and social handicaps. Ten mutilated children were treated from January 1986 to January 1999 in Hospital de Dona Estefaˆ nia, Lisbon, Portugal. One was recovering from hemolytic-uremic syndrome with a severe combined immunodeficiency, another malnourished, anemic child had malaria, and three had chicken pox (in one case complicated by meningococcal septicemia). There were three cases of meningococcal and two of pyocyanic septicemia (one in a burned child and one in a patient with infectious mononucleosis). The lower limbs (knee,leg, foot) were involved in five cases, the face (ear, nose, lip) in four, the perineum in three, the pelvis (inguinal region, iliac crest) in two, the axilla in one, and the upper limb (radius, hand) in two. Primary prevention is based on early recognition of risk factors and timely correction. Secondary prevention consists of immediate etiologic and thrombolytic treatment to restrict the area of necrosis. Tertiary prevention relies on adequate rehabilitation with physiotherapy and secondary operations to obtain the best possible functional and esthetic result.

Perinatal Death: Epidemiology and Etiology

Perinatal mortality rate is an important mark to evaluate women and perinatal health care. It is of utmost importance to know causes and the evolution of its two components aiming to improve health care in different fields – sanitary conditions, diagnosis and treatment of infectious disease, immunisations, diagnosing and caring for medical diseases induced by pregnancy or directly related to it, providing skilled birth attendance, preventing birth asphyxia, preventing preterm birth complications and infections. In high-income countries the epidemiology varies mainly with social and economic conditions; in low-income countries, paired with poverty, undernutrition, superstition, lack of medical care, deficient basic sanitary conditions are also found. Also, in rich countries, responsible for 1% of deaths, data are published and improvements evaluated, while in low-income countries responsible for 99% of deaths numbers and causes are unknown, making difficult to implement cost effective interventions, a reason why “stillbirth rates in low-income countries are now where they were in high-income countries 50 to 100 years ago”. Knowledge on causes of death are very important as often what is needed are “simple” measures as improvement of sanitary conditions and immunisation programmes rather than high technologies. About four million babies dye each year in the first 28 days of life and another 3 million dye before birth in the third-trimester, with 98% occurring in low-income and middle income countries and more than 1 million occurring during labour and delivery. Classically stillbirths are the major component of perinatal mortality rate. Causes of death are even more difficult to know. In low-income countries a great proportion of women give birth at home. Worldwide the main causes of stillbirth are asphyxia due to obstructed labour, eclampsia, abruption placenta and umbilical cord complications - making valid the assumption that skilled birth attendance would decrease stillbirth; and infection - chorioamnioitis, syphilis and malaria. In high-income countries placental pathology and infection, congenital anomalies, complications of preterm birth and post term delivery, are the most common. If in low-income countries famine and lack of provisions and health care are common, in high-income countries, advanced maternal age and diabetes, obesity, hypertension, smoking, are frequent findings.

Internamento por Malária Importada em Crianças, em Dois Hospitais da Grande Lisboa

Introdução: Apesar de em Portugal não haver malária endógena,a crescente mobilidade das populações e os laços históricos com África possibilitam a importação de casos para o nosso país. O presente estudo pretende contribuir para melhorar o conhecimento epidemiológico e clínico da malária importada na região de Lisboa. Métodos: Realizou-se um estudo descritivo das crianças com malária, internadas em dois hospitais da Grande Lisboa, durante um período de seis anos (1999-2004). Resultados: Foram identificados 134 casos, sendo a mediana das idades de sete anos. A maioria (93,3%) era de origem africana e referia estadia em região endémica (90%). O Plasmodium falciparum foi o agente etiológico mais frequente (73%). A febre foi a manifestação clínica mais frequente, seguida de manifestações gastrointestinais e cefaleias. Ocorreram complicações em 42% dos doentes, sendo a trombocitopenia (19,4%) e a anemia grave (9%) as mais frequentes. A halofantrina e o quinino foram os anti-maláricos mais usados. Conclusões: A malária importada é uma patologia relativamente comum na Grande Lisboa e, dada a inespecificidade do quadro clínico, todas as crianças febris ou doentes com estadia recente num país endémico devem ser rastreadas para esta entidade.

Malária Grave em Cuidados Intensivos

Objectivo: Rever o perfil clínico e terapêutico dos doentes com malária grave admitidos numa unidade de cuidados intensivos (UCI). Tipo de estudo: Retrospectivo. População: Nove doentes com malária a Plasmodium falciparum admitidos entre Agosto de 1991 e Julho de 2001 na UCI do Hospital de Santo António dos Capuchos (HSAC). Resultados: As complicações mais frequentes foram as manifestações neurológicas, a síndroma de dificuldade respiratória aguda (SDRA) e a insuficiência renal aguda. A ventilação mecânica foi utilizada em cinco doentes, a prótese renal em dois e as aminas vasopressoras em três doentes. Faleceram dois doentes (22.2%). Conclusões: A malária a Plasmodium falciparum é uma doença potencialmente fatal, pelo que os factores de risco e os critérios para admissão em UCI devem ser identificados. A presença de disfunção de órgão, nomeadamente de manifestações neurológicas, insuficiência renal e respiratória deverão ser consideradas como indicação para internamento em cuidados intensivos.

Formas Malignas de Malária por Plasmodium Falciparum

A propósito de 2 Casos Clínicos de malária maligna internados na U.C.I. do Hospital Curry Cabral(em 1983 e 1984), um dos quais de evolução letal, chama-se a atenção para a necessidade do seu diagnóstico precoce.
