This is a case report of a 44-year-old male living in Teresópolis, RJ, Brazil, probably poisoned by contact with a Lonomia caterpillar, who presented hemolytic anemia, decreased platelet count and acute renal insufficiency. Lonomia erucism diagnosis was established by anamnesis and clinical and laboratory manifestations. Therapeutic measures consisting of hemotransfusion and hemodialysis were successful. Physiopathologic and clinical features of erucism by Lonomia are discussed.
Objective: To evaluate the loss of correction after treatment of spine deformities with the technique of isolated posterior vertebrectomy. Methods: Twenty-one patients were followed-up for three years after surgery with panoramic X-rays, CT scans, SF-36 and Oswestry questionnaires. We evaluated the loss of correction, CAGE subsidence and the evolution of the pelvis-T1 angle during follow-up. The correlation among the radiographic changes and functional and quality of life scores was also assessed. Results: All patients had some degree of loss of correction and subsidence of CAGE, especially in the first year of follow-up. Such losses exerted negative impact on the function, pain and self-image of the patients. Factors such as the stiffness of the fusion mass and size of implant used appear to have contributed to the occurrence of subsidence, regardless of age and bone mineral density. Conclusions: The use of spacers with larger cross-sectional diameter and more rigid rods can reduce the overloading on the anterior column of Denis, reducing the subsidence and loss of correction. Additional stabilization strategies such as the use of orthoses postoperatively can also be useful, and should be evaluated in subsequent studies.
Agradeço primeiramente a Deus, por me proporcionar novamente esta oportunidade de cursar uma universidade, agradeço a ele também por seu grande amor puro e verdadeiro. Aos meus pais Manoel e Sueli, aos meus irmãos Andréia e Alexandre e ao meu filho Renan que fazem parte da minha vida não somente nos momentos alegres, mas principalmente nos momentos mais difíceis.
OBJETIVO: A proposta do estudo foi determinar nossos resultados clínicos e radiográficos de pacientes com deformidades congênitas da coluna vertebral submetidos à ressecção de hemivértebra por via posterior isolada e correção com instrumentação posterior e fusão. MÉTODOS: Registros de 31 pacientes submetidos à ressecção de hemivértebra no período de 2003 a 2010 foram revistos para identificar idade e sexo, grau de correção, níveis da artrodese, quadro neurológico, perda sanguínea, tempo cirúrgico e complicações. RESULTADOS: Foram identificados 22 pacientes com escoliose e Cobb pré-operatório médio de 46.66°(20-88°) e 9 pacientes com cifose e média angular de 83.54°(13-137°). Vinte e quatro pacientes eram do sexo feminino e 7 do sexo masculino. Foram 13 pacientes adolescentes e 18 crianças (1-19 anos). A ressecção de hemivértebra foi realizada em 1 nível (64%), 2 níveis (32%) e 3 níveis (4%). As taxas de correção da escoliose e cifose foram 63.8 e 40.1% e as médias angulares pós-operatórias foram 16.88° e 50°, respectivamente. Complicações ocorreram em 7 pacientes: pseudartrose, cifose juncional, neurite óptica, déficit neurológico, infecção de ferida operatória e óbito. A média de perda sanguínea foi de 1132ml (300ml-3500ml) e o tempo cirúrgico foi de 7.15 horas (4-13 horas). CONCLUSÕES: A ressecção de hemivértebra é uma valiosa técnica no tratamento das deformidades congênitas angulares e uma alternativa eficiente que oferece correção satisfatória nos planos coronal e sagital sem a necessidade de uma abordagem anterior.
Objective: Evaluate the results after decompression and stabilization of craniocervical junction in patients with mucopolysaccharidosis (MPS). Method: Retrospective study of 10 patients with MPS through the analysis of medical records and additional tests. Result: All patients with mid-term and long-term follow-up achieved consolidation of the arthrodesis and 87.5% had neurological improvement of Nurick score. Conclusion: Early diagnosis and intervention in cases of stenosis and/or craniocervical instability of patients with MPS provide patients a good recovery of neurological function, despite the great technical difficulty and risk of complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
