Community introduction of practice parameters for autistic spectrum disorders: Advancing early recognition.

OBJECTIVES: Within a strong interdisciplinary framework, improvement in the quality of care for children with autistic spectrum disorders through a 2 year implementation program of Practice Parameters, aimed principally at improving early detection and intervention. METHOD: We developed Practice Parameters (PPs) for Pervasive Developmental Disorders and circulated the PPs to all child and adolescent psychiatrists practicing in the region. RESULTS: PP development and parallel information strategies resulted in a significant decrease of 1.5 years in the mean-age-at-diagnosis. However, further analysis indicated that improvement was only transient. CONCLUSION: Despite the encouraging improvement in mean-age-at-diagnosis 2 years after PP implementation, other indicators showed a failure to maintain the improvements. A systematic screening program would be the most reliable method to reinforce the PPs.

Artrodesis de tobillo: resultados comparativos de diferentes técnicas

INTRODUCTION: Ankle arthrodesis in an intervention that may be performed using a variety of surgical approaches. The joint may be stabilized using diferent systems, with or without bone graft. MATERIAL AND METHODS: Retrospective study that collected the results of 40 patients who underwent ankle arthrodesis; the complications that arose were analyzed, results according to the AOFAS clinical rating system, global patient satisfaction and the relationship with the articular approach route, the !xation system or the usage of grafts.RESULTS: 55% of the patients presented one or more complication that motivated a total of 12 re-interventions in 10 patients (excludes removal of osteosynthesis material). The absence of consolidation, which required a new arthrodesis was more frequent in patients where osteosynthesis was not used (two out of three cases) than in those using screws (four out of 24 cases), while there was no register of this in 13 patients in which intramedullary pin. The use of the distal extreme of the fibula or the iliac crest as bone graft has failed to improve the consolidation. Arthroscopic approaches avoid the appearance of soft tissue complications, although the consolidation disorders were more frequent. The average score on the AOFAS clinical rating system was 56.4±21.2 and 55% of the patients were satisfied. CONCLUSIONS: Although the case histories fail to provide significant results, it is a demanding intervention, with an elevated complication rate. Intramedullary pins seem to favor improved consolidation.

Immunological response to re-infections with clones of the Colombian strain of Trypanosoma cruzi with different degrees of virulence: influence on pathological features during chronic infection in mice

Re-infections with Trypanosoma cruzi are an aggravating factor for Chagas disease morbidity. The Colombian strain of T. cruzirepresents multiclonal populations formed by clonally propagating organisms with different tropisms and degrees of virulence. In the present study, the influence of successive inoculations with clones of the Colombian strain, exhibiting different degrees of virulence, on chronic myocarditis and the humoral and cellular immune responses (Col-C1 high virulence, Col-C8 medium virulence and Col-C5 low virulence) were demonstrated. Mice from three groups with a single infection were evaluated during the acute (14th-30th day) and chronic phases for 175 days. An immunofluorescence assay, ELISA and delayed type hypersensitivity (DTH) cutaneous test were also performed. Mice with a triple infection were studied on the 115th-175th days following first inoculation. The levels of IgM and IgG2a were higher in the animals with a triple infection. DTH showed a higher intensity in the inflammatory infiltrate based on the morphometric analysis during a 48 h period of the triple infection and at 24 h with a single infection. The histopathology of the heart demonstrated significant exacerbation of cardiac inflammatory lesions confirmed by the morphometric test. The humoral responses indicate a reaction to the triple infection, even with clones of the same strain.
