Sea urchin granuloma

Os acidentes por animais aquáticos traumatizantes e venenosos podem provocar morbidez importante em humanos. Equinodermos marinhos incluem mais de 6000 espécies de estrelas-do-mar, ouriços-do-mar, bolachas-de-praia e pepinos-do-mar. Vários equinodermos têm sido responsabilizados por acidentes em humanos. Granulomas por ouriço-do-mar são lesões de caráter granulomatoso, crônicas, causada por acidentes com espículas de ouriço-do-mar. Os autores relatam um caso típico de granulomas por ouriço-do-mar ocorrido em um pescador e enfatizam as implicações terapêuticas aplicadas.

Pre- and post-transplant anti-myosin and anti-heat shock protein antibodies and cardiac transplant outcome

Background: the purpose this study was to investigate the relationship of anti-myosin and anti-heat shock protein immunoglobulin G (IgG) serum antibodies to the original heart disease of cardiac transplant recipients, and also to rejection and patient survival after cardiac transplantation.Methods: Anti-myosin and anti-heat shock protein (anti-hsp) IgG antibodies were evaluated in pre-transplant sera from 41 adult cardiac allograft recipients and in sequential post-transplant serum samples from 11 recipients, collected at the time of routine endomyocardial biopsies during the first 6 months after transplantation. In addition, the levels of these antibodies were determined from the sera of 28 healthy blood donors.Results: Higher anti-myosin antibody levels were observed in pre-transplant sera than in sera from normal controls. Moreover, patients with chronic Chagas heart disease showed higher anti-myosin levels than patients with ischemic heart disease, and also higher levels, although not statistically significant, than patients with dilated cardiomyopathy. Higher anti-hsp levels were also observed in patients compared with healthy controls, but no significant differences were detected among,the different types of heart diseases. Higher pre-transplant anti-myosin, but not anti-hsp, levels were associated with lower 2-year post-transplant survival. In the post-transplant period, higher anti-myosin IgG levels were detected in sera collected during acute rejection than in sera collected during the rejection-free period, whereas anti-hsp IgG levels showed no difference between these periods.Conclusions: the present findings are of interest for post-transplant management and, in addition, suggest a pathogenic role for anti-myosin antibodies in cardiac transplant rejection, as has been proposed in experimental models of cardiac transplantation.

Abuso sexual, transtornos mentais e doencas fisicas

Objective: to review and describe the different organic and psychic consequences of sexual abuse. Methodology: 71 papers were sorted in a ten-year literature search (1987-1997) in MedLine and Lilacs (South American Literature Index), besides 14 books in the subject. Results: sexual abuse is much less frequent (or less reported) in Brazil: 7% of the population, while in the USA the prevalence is 12.9% to 28% of women and 2% to 9% of men. Results showed women being more frequently sexually abused but less differences in physical abuse were found between genders. There was a significant association between sexual abuse and the following: eating disorders, depression, irritable bowel, chronic pain (mainly pelvic), neurological, rheumatic and venereal disorders. This association was not observed in chronic constipation, Chron disease and dissociative disorders. Conclusions: although it is important to think of sexual/physical abuse as a predisposing factor to several illnesses, caution is necessary specially in cultures with different moral and ethical values. Research in this subject in Brazil should be conducted with patients in treatment, using control groups, in order to take advantage of the existing rapport. It would be also quite important to separate acute and chronic abuse effects, as well as getting to know the meaning of the experienced abuse to each person.

El tratamiento fisioterapéutico ¿es efectivo en el mantenimiento físico y en la reducción del declive cognitivo de las demencias?

Introduction. Dementia is a chronic and neurodegenerative disease responsible for a progressive decline of cognition and physical capacity. Objective: To verify the effectiviness of three months of physiotherapy intervention on cognitive functions and balance of institutionilized elderly people with dementia. Patients and methods. This study has comprised thirty subjects, divided in two groups: EG (experimental group) and CG (control group). EG was composed by 15 participants with mean age of 71,6 ± 8,5 years and scholarity of 4,7 ± 4,2 years. CG was formed by 15 subjects with mean age of 78,5 ± 7,6 years and scholarity of 2,2 ± 1,8 years. The sample was evaluated by means of the following instruments: Mini-Mental State Examination, Semantic Verbal Fluency test, Clock Drawing test, Berg Balance Scale and Timed Get Up and Go test. The statistical procedures were done by means of Multivariate Analisis of Variance (MANOVA), with significance of 5 % (p < 0,05). Results. The results has shown a heterogeneity of both groups related to age (F = 0,2, p < 0,05) and scholarity (F = 2,6, p < 0,05). MANOVA pointed beneficts of physiotherapy on balance (F = 7,3, p < 0,01) but not on cognitive functions (F = 0,3, p > 0,05). Conclusions. Three months of physiotherapy were effective to improuve physical capacity of institucionilized elderly people with dementia. Neverthless, it was not able to minimize cognitive decline commonly seen on dementia. The question if a prolonged intervention could propitiate cognitive beneficts remains, specially in a more homogeneous groups.

Polimorfismos do complexo de genes KIR predispõem à hanseníase e modulam seu desenvolvimento para a forma paucibacilar

A hanseníase é uma infecção crônica e granulomatosa da pele e nervos periféricos, que infecta principalmente macrófagos e células de Schwann. A Organização Mundial de Saúde classifica a hanseníase em duas formas polares: multibacilar e paucibacilar, de acordo com o índice baciloscópico e a resposta imune do hospedeiro. As células natural killer (NK) têm um importante papel na infecção, sendo a primeira forma de defesa contra organismos intracelulares. As células NK utilizam muitos tipos de receptores de superfície celular, como os receptores imunoglobulina-símiles de célula NK (KIR), que podem inibir ou ativar a resposta citolítica de NK, através do reconhecimento de moléculas do complexo de histocompatibilidade principal (MHC) de classe I na célula alvo. Nesse estudo caso controle, a presença ou ausência de 15 genes KIR e seus ligantes HLA-C foram investigadas, na intenção de se descrever sua variabilidade genotípica, associação com a hanseníase e sua evolução clínica. A genotipagem do complexo de genes KIR e dos grupos NK1 e NK2 de HLA-C foi feita por PCR-SSP em 105 pacientes e 104 controles. KIR2DL2 e KIR2DL3, na presença do seu ligante HLA-Cw parece predispor à hanseníase (p=0,046; X²= 3,97; OR=1,99; IC 95%= 1,00-3,97). Além disso, a prevalência da hanseníase ao redor do mundo e as freqüências de KIR2DL2 se correlacionaram positivamente. Esse achado, juntamente com a associação entre KIR2DL3 e a tuberculose, descrita por outros autores, sugere que esses genes de receptores inibitórios predispõem à doença. Adicionalmente, o gene KIR2DS2 foi associado com o desenvolvimento da hanseníase paucibacilar (p=0,009; X²= 7,23; OR=3,97; IC 95%= 1,37-9,96), possivelmente modulando o desenvolvimento para a forma mais branda da doença.
