Leque de Malformações Congénitas Associadas às Fissuras do Lábio Alvéolo Palatinas

As malformações congénitas associadas às fissuras lábio alvéolo palatinas abrangem um largo leque de patologias, com incidência e penetrância muito variáveis consoante os aurores. Nos 284 doentes seguidos e/ou referenciados a Consulta de Fissurados do Hospital de Dona Estefania (H.D.E.), estão descritas malformações associadas em 78 (27,5%). Destes, há consanguinidade dos pais em três casos e incidência familiar de fissuras e/ou outras malformações congénitasem 13 e 10 doentes respectivamente. Trinta doentes têm síndromes malformativas bem definidas. Nos restantes 48 identificaram-se 127 malformações congénitas associadas (M.C.A.) sendo segundo os critérios de Smith, 81 major e 46 minor. As malformações associadas mais frequentes são as da face ( 25,9 %) e do sistema cardiovascular (16,5 %).As anomalias múltiplas(de vários sistemas) são as mais frequentes (47.9 %), seguindo-se a anomalia isolada (29,1 %) e a múltipla de um sistema (22,9%). Quanto à associação de síndromes com o tipo de fissura, palato primário, secundário ou total, as do secundário são as mais frequentes, nomeadamente a Sequência de Pierre Robin (S.P.R.) - 19 em 36 fendas do palato secundário.

Isolated Cleft of the Anterior Mitral Valve Leaflet

Isolated anterior mitral leaflet cleft (not associated with atrio-ventricular septal defect) is a rare cause of congenital mitral regurgitation, and the treatment consists of direct suturing of the cleft. We present a clinical case with this entity.

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.

Tratamento Cirúrgico dos Defeitos do Septo Auriculo-Ventricular. Experiência Uni-Institucional

OBJECTIVES: Atrio-ventricular septal (AVSD) defects include a variable spectrum of congenital malformations with different forms of clinical presentation. We report the surgical results, from a single institution, with this type of congenital cardiac malformation. Patients with hypoplasia of one of the ventricles were excluded from this analysis. POPULATION: Between November of 1998 and June of 2005, 49 patients with AVSD were operated on by the same team and in the same department. The average age was 37.3 months (medium 6 months) and 31 patients were female. In 38 patients (78%) an inter-ventricular communication was present (AVSD-complete) and of these, 26 were of the type A of Rastelli, being 13 of type B or C. The age for defect correction of the complete form was of 5.5 months, palliative surgery was not carried out on any of the patients. Associated lesions included: Down's syndrome in 22 patients (45%), patent arterial duct in 17 patients (35%), severe AV regurgitation in 4 patients (8%), tetralogy of Fallot in two (4%) and sub-aortic stenosis in one patient (2%). Pre-operatively 10 patients presented severe congestive heart failure and two were mechanically ventilated. RESULTS: Complete biventricular correction was carried out in all patients. The average time on bypass (ECC) was 74.1+/-17.5 min. and time of aortic clamping was 52.0+/-12.9 min. The complete defects were corrected by the double patch technique, and in all patients the mitral cleft was closed, except in two with single papillary muscle. There was no intra-operative mortality, but hospital mortality was 8%(4 patients), due to pulmonary hypertension crises, in the first 15 post-operative days. The mean ventilation time was of 36.5+/-93 hours (medium 7 h) and the average ICU stay was of 4.3+/-4.8 days (medium 3 days). The minimum follow-up period is 1 month and the maximum is 84 months (medium 29.5 months), during which time 4 re-operations (8%) took place: two for residual VSD's and two for mitral regurgitation. There was no mortality at re-do surgery. At follow up there was residual mitral regurgitation, mild in 17 patients and moderate in two. Four other patients presented with minor residual defects. CONCLUSIONS: The complete correction of AVSD can be carried out with acceptable results, in a varied spectrum of anatomic forms and of clinical severity. Despite the age of correction, for the complete forms, predominantly below 12 months, pulmonary hypertension was the constant cause for post operative mortality. Earlier timing of surgery and stricter peri-operative control might still improve results.

Hemangioma Infantil Ulcerado do Sulco Interglúteo Tratado com Timolol Tópico

Dados recentes revelam resultados promissores com a utilização de beta-bloqueante tópico no tratamento dos hemangiomas infantis ulcerados. Os autores descrevem o caso clínico de uma lactente pré-termo de 6 meses de idade com um hemangioma infantil ulcerado do sulco interglúteo tratado com bom resultado clínico com timolol tópico.
