Asfixia perinatal e problemas cardíacos

OBJETIVO: Avaliar a gravidade das complicações cardíacas na asfixia neonatal, sua evolução e correlacioná-las com o grau e duração do processo hipóxico. MÉTODOS: Foram estudados 90 bebês nos últimos 7 anos com grau de Apgar <6 no 5°min de vida. Pelo protocolo, após o exame físico e os cuidados intensivos, eram submetidos a dosagem do pH arterial, CPK-MB, DHL, glicemia, além da realização de radiografia de tórax, eletrocardiograma (ECG), ecocardiograma, seriados e repetidos a cada semana. Aqueles que faleceram eram levados à necropsia. RESULTADOS: Dos 90, 73 (81%) eram prematuros, 30 (41%) eram apropriados para a idade gestacional (AIG) e 43 (59%) eram pequenos(PIG). Em 21 (23%) casos havia pH arterial <7,2. Os quadros clínicos mais observados foram: pneumonia em 28 (31%), anemia 24 (26%) e icterícia moderada 12 (5%), entre outros. Ao exame físico observaram-se: sopro sistólico em 46 (50%), ictus propulsivo 18 (20%) e ICC em 8 (9%). No ECG, os sinais mais freqüentes foram alterações de repolarização (ST e T) em 44 (49%). No ecocardiograma, observou-se persistência do canal arterial (PCA) em 20 (22%), regurgitação tricúspide em 6 (7%), hipertensão pulmonar em 6 (8%), hipocontratilidade de VE e dilatação de VD em 4 (5%). Dos 23 óbitos, 14 foram estudados e as alterações mais freqüentes foram necrose de fibras em 8 (68%) casos e em 4 (29%) congestão, vacuolização e perda de estriação. CONCLUSÃO: A maioria teve evolução favorável mesmo naqueles que tiveram acidemia importante. Muitas alterações de ECG e ecocardiograma se normalizaram. Daqueles que evoluíram para o óbito, as lesões mais graves ocorreram nos que sofreram, por mais tempo, processo anóxico.

Internet au service du patrimoine. Cartographie dynamique de l'inventaire des géotopes d'importance nationale

L'inventaire des géotopes d'importance nationale, aujourd'hui proche de son état final, est le fruit d'un long travail de sélection, de documentation ainsi que de définition et de numérisation des périmètres des sites initié dans les années 1990 par le groupe de travail pour la protection des géotopes en Suisse (Strasser et al. 1995, Berger et al. 2008). Il représente un outil au service de la diffusion et à la promotion du géopatrimoine suisse, auprès de la population en général et des professionnels des géosciences en particulier, dans un but de valorisation patrimoniale et de protection et par une sensibilisation à la valeur particulière et à la vulnérabilité des géotopes.¦C'est dans cet objectif qu'a été développée une interface cartographique rendant accessible sur Internet le contenu de cet inventaire. L'outil de web mapping utilisé - GoogleMaps API - permet en effet d'enrichir une interface de navigation intuitive de diverses fonctions additionnelles offertes par la cartographie sur internet (Kraak 2004, Plewe 2007). La carte n'est donc pas seulement une représentation de la réalité permettant la localisation de différents objets, mais également un outil de recherche thématique et spatiale ainsi qu'un index reliant chaque objet cartographié à diverses informations.¦Porte d'accès aux données des site à une échelle individuelle ou globale, mais aussi outil d'exploration, cette interface propose plusieurs niveaux d'utilisation, correspondant aux diverses interactions possibles avec ces données : naviguer et découvrir les sites, réaliser des sélections multiples, comparer les géotopes à d'autres données, comme l'inventaire fédéral des paysages. L'utilisateur peut ainsi produire à chaque fois la carte qui répond à ses besoins et à ses questions. En donnant à tous accès au contexte et aux particularités de chaque site par delà la globalité abstraite de l'inventaire, cette application se veut avant tout un outil au service de la médiation du géopatrimoine.

Results of computer assisted navigation in Total Knee Arthroplasty (TKA): comparison with the conventional method

The aim of this retrospective study was to compare the clinical and radiographic results after TKA (PFC, DePuy), performed either by computer assisted navigation (CAS, Brainlab, Johnson&Johnson) or by conventional means. Material and methods: Between May and December 2006 we reviewed 36 conventional TKA performed between 2002 and 2003 (group A) and 37 navigated TKA performed between 2005 and 2006 (group B) by the same experienced surgeon. The mean age in group A was 74 years (range 62-90) and 73 (range 58-85) in group B with a similar age distribution. The preoperative mechanical axes in group A ranged from -13° varus to +13° valgus (mean absolute deviation 6.83°, SD 3.86), in group B from -13° to +16° (mean absolute deviation 5.35, SD 4.29). Patients with a previous tibial osteotomy or revision arthroplasty were excluded from the study. Examination was done by an experienced orthopedic resident independent of the surgeon. All patients had pre- and postoperative long standing radiographs. The IKSS and the WOMAC were utilized to determine the clinical outcome. Patient's degree of satisfaction was assessed on a visual analogous scale (VAS). Results: 32 of the 37 navigated TKAs (86,5%) showed a postoperative mechanical axis within the limits of 3 degrees of valgus or varus deviation compared to only 24 (66%) of the 36 standard TKAs. This difference was significant (p = 0.045). The mean absolute deviation from neutral axis was 3.00° (range -5° to +9°, SD: 1.75) in group A in comparison to 1.54° (range -5° to +4°, SD: 1.41) in group B with a highly significant difference (p = 0.000). Furthermore, both groups showed a significant postoperative improvement of their mean IKSS-values (group A: 89 preoperative to 169 postoperative, group B 88 to 176) without a significant difference between the two groups. Neither the WOMAC nor the patient's degree of satisfaction - as assessed by VAS - showed significant differences. Operation time was significantly higher in group B (mean 119.9 min.) than in group A (mean 99.6 min., p <0.000). Conclusion: Our study showed consistent significant improvement of postoperative frontal alignment in TKA by computer assisted navigation (CAS) compared to standard methods, even in the hands of a surgeon well experienced in standard TKA implantation. However, the follow-up time of this study was not long enough to judge differences in clinical outcome. Thus, the relevance of computer navigation for clinical outcome and survival of TKA remains to be proved in long term studies to justify the longer operation time. References 1 Stulberg SD.

The Genus Cyclospora (Apicomplexa: Eimeriidae), with a description of Cyclospora schneideri n.sp. in the snake Anilius scytale scytale (Aniliidae) from Amazonian Brazil: a review

A review is made of the recorded species of the coccidian genus Cyclospora and major events leading up to the discovery of C. cayetanensis, which is responsible for serious outbreaks of diarrhoea in man and is one of the aetiological agents of "traveller's diarrhoea". Humans appear to be the specific hosts, with the entire life-cycle in the intestine: to date there is no convincing evidence that the disease is a zoonosis. A description is given of oocysts and endogenous stages of C. schneideri n.sp., in the snake Anilius scytale scytale. Sporulation is exogenous and completed after about one week at 24-26º. Mature oocysts 19.8 × 16.6 (15.1 × 13.8-25.7 × 20.1), shape-index 1.2 (1.0-1.3): no oocyst residuum or polar bodies. Oocyst wall a single colourless, smooth layer with no micropyle: it is rapidly deformed or broken. Sporocysts 13.6 × 9.4 (11.3 × 8.3-15.1 × 9.9), shape-index 1.4 (1.2-1.5) with an inconspicuous Stieda body. Sporozoites 11-13 × 2.5-3. Endogenous stages are intracytoplasmic in the epithelial cells of the small intestine and with the characters of the Eimeriorina.
