ABSTRACT
OBJETIVOS: Verificar a relação entre o ângulo da articulação metatarsofalangeana I (Ang-I) e a idade, as medidas antropométricas e a postura dos pés de mulheres e homens idosos. MÉTODOS: A amostra foi composta por 227 mulheres idosas, com média de idade de 69,6 anos (±6,8) e 172 homens idosos, com média de idade de 69,4 anos (±6,7). As variáveis estudadas foram: a largura e o perímetro da cabeça dos metatarsos, a altura da cabeça do metatarso I e do dorso do pé, o comprimento do pé, os ângulos articulares Ang-I e metatarsofalangeana V, o índice do arco e o índice postural do pé. As medidas foram tomadas com instrumentos analógicos. Os dados foram analisados por meio de Correlação de Pearson. RESULTADOS: O Ang-I não apresentou relação com a idade e com o índice do arco, porém apresentou associação positiva com a largura e o perímetro da cabeça dos metatarsos, com o índice postural do pé e com o ângulo da articulação metatarsofalangeana V e associação negativa com a altura do dorso do pé. CONCLUSÕES: Foram encontradas relações entre maior Ang-I e maiores largura e perímetro de antepé, maior ângulo da articulação metatarsofalangeana V, pés mais pronados e com menor altura do dorso do pé.
OBJECTIVES: To investigate the relationship between the first metatarsophalangeal joint angle (Ang-I), the age, anthropometric measures and foot posture of older adults. METHODS: The sample was composed of 227 older women with a mean age of 69.6 (±6.8) years and 172 older men with a mean age of 69.4 (±6.7) years. The studied variables were: the width and circumference of the metatarsal heads, the height of the first metatarsal head and the dorsum of the foot, the length of the foot, the Ang-I and fifth metatarsophalangeal joint angles, the arch index and the foot posture index. The measurements were taken with analog instruments. The data were analyzed using Pearson's correlation. RESULTS: There was no association between Ang-I and age or arch index, but there were positive associations between Ang-I and the width and circumference of the metatarsal heads, the foot posture index and the fifth metatarsophalangeal angle. There was a negative association between Ang-I and the height of the dorsum of the foot. CONCLUSIONS: Relationships were found between greater Ang-I values and greater widths and circumferences of the forefeet, greater fifth metatarsophalangeal angles and greater pronation of the feet and smaller values for the height of the dorsum of the foot.
ABSTRACT
OBJETIVO: Verificar o efeito do primeiro ano do Programa de Revitalização de Adultos no número de episódios de quedas e a sua relação com a evolução da força muscular, da flexibilidade e do equilíbrio dinâmico. MÉTODO: 94 indivíduos (79 mulheres e 15 homens) que participaram do Programa de Revitalização de Adultos em São Carlos, SP, por um ano, foram avaliados quanto à força de preensão manual, flexibilidade, equilíbrio dinâmico e episódios de quedas em cinco momentos diferentes: uma avaliação inicial seguida por outras quatro, com intervalos de três meses entre elas. RESULTADOS: Mulheres e homens experimentaram ganho de flexibilidade e de equilíbrio ao longo do programa, porém não reduziram o número de quedas significativamente. Apenas as mulheres melhoraram a força muscular. Os indivíduos que relataram ter caído pelo menos uma vez no decorrer do ano (28,72 por cento dos participantes) ganharam força e flexibilidade, porém o equilíbrio dinâmico não melhorou. Nesse grupo, o número médio de quedas reduziu-se entre a primeira e a terceira avaliação, porém aumentou entre a terceira e a quarta avaliação, intervalo que coincidiu com o período de descanso das atividades físicas. O grupo de indivíduos que não caiu apresentou ganho no equilíbrio e na flexibilidade, mas não na força de preensão manual. CONCLUSÕES: Após um ano, o número de quedas dos participantes do Programa de Revitalização de Adultos não reduziu de forma significativa. Entre os participantes que caíram pelo menos uma vez ao longo do período estudado, a evolução do número de quedas se deu de maneira inversa à evolução da força e do equilíbrio dinâmico, mas não apresentou relação com a evolução da flexibilidade.
OBJECTIVE: To assess the effect of the first year of an Adult Revitalization program on the number of occurrences of falls, and its relationship with the evolution of muscle strength, flexibility and dynamic balance. METHOD: 94 individuals (79 women and 15 men) who participated in an Adult Revitalization program in São Carlos, State of São Paulo, Brazil, for one year were evaluated regarding their hand grip strength, flexibility, dynamic balance and occurrences of falls on five occasions: an initial evaluation followed by four others at three-month intervals. RESULTS: The women and the men experienced gains in flexibility and balance over the course of the program, but there was no significant reduction in the number of falls. Only women improved their muscle strength. The individuals who reported having fallen at least once during that year (28.72 percent of the participants) gained strength and flexibility, but their dynamic balance did not increase. In this group, the mean number of falls decreased between the first and the third evaluation, but increased between the third and the fourth evaluation, which coincided with the period of resting from physical activities. The individuals who did not fall presented gains in balance and flexibility but not in their hand grip strength. CONCLUSION: After one year, the number of falls among the participants in the Adult Revitalization program did not decrease significantly. Among the participants who fell at least once during the study period, the improvement in the number of falls occurred inversely to the improvement in handgrip strength and dynamic balance, but did not present any relationship with the improvement in flexibility.

Crotalus envenomation is the second most frequent condition caused by venomous snakes attacking dogs and cats in Brazil. Affected animals show severe neurological and muscular involvement, lower motor neuron signs and myalgia due to extensive rabdomiolysis. The present case report is about Crotalus envenomation in a dog which showed severe clinical and laboratory abnormalities. After treatment with antivenom (specific antidote) and clinical support, the dog totally recovered from that condition.

Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, a coccidian protozoan of worldwide distribution. The seroprevalence in canine population can be an alternative for measuring T. gondii urban spreading. A total of 780 blood samples from dogs were collected, during the yearly anti-rabies campaign, carried out by the Department of Veterinary Hygiene and Public Health, School of Veterinary Medicine and Animal Husbandry (FMVZ), São Paulo State University, UNESP, together with the county health authorities, in August 1999. Using Indirect Fluorescent Antibody Test (IFAT) for detecting antibodies anti-T. gondii in the sera samples, we observed that 258 dogs (33.1 percent) were positive. The associations between the serological results and the epidemiological variables were studied. Statistically significant differences were not found regarding sex (32.2 percent male and 34.3 percent female reactors). Dogs without a defined breed showed seropositivity statistically higher than the pedigreed group. The occurrence of infection was considered higher with age.

Detection of Toxoplasma gondii (T. gondii) DNA in blood can help to diagnose the disease in its acute phase; however, it must be considered that hemoglobin, present in blood, can inhibit polymerase activity, making impracticable the detection of DNA in samples. Mice were experimentally infected via oral route with ME49 and BTU2 strains cysts and RH strain tachyzoites; polymerase chain reaction was used to detect T. gondii DNA in mice sera 18, 24, 48, 96, and 192 hours post infection (PI). Toxoplama gondii DNA was detected in only one animal infected with BTU2 strain, genotype III (isolated from a dog with neurological signs) 18 hours PI. The agents DNA was not detected in any sample of the other experimental groups. New studies must be carried out to verify the technique sensitivity in researches on this agents genetic material using sera samples of acute-phase toxoplasmosis patients, especially in cases of immunosuppression

Visceral leishmaniasis is a zoonotic disease caused by parasites of the Leishmania genus. Dog is the major source of infection to man, especially in urban areas. The authors report a case of visceral leishmaniasis in a pit bull female dog from Bocaina, São Paulo, Brazil. The animal presented clinical signs compatible with leishmaniasis, including skin lesions in the body and partial damage of the external ears. The indirect fluorescent antibody test (IFAT) demonstrated a titer of 1280, and promastigote forms of Leishmania sp were isolated by the culture of bone marrow puncture. Cytological analysis of the lymph node and smear of the bone marrow puncture revealed macrophages containing amastigote forms of Leishmania sp in their inner region. The test of Polymerase Chain Reaction (PCR) utilized the primers LINR4 and LIN19, which amplify 720 base pairs, specific for Leishmania sp. The authors discuss the importance of techniques for a quick and precise diagnosis to this serious zoonosis with great impact in animal and public health
