Abstract: bilateral hemifacial spasm (bhs) is a rare focal movement disorder often associated with vascular compression of both facial nerves. the contractions are usually asymmetric and asynchronous. typically, one side is affected first and there is a long but variable interval for the symptoms on the other side to occur. bhs must be differentiated from other conditions including blefarospasm, facial myokymia, facial tics, oromandibular dystonia, and hemimasticatory spasm. the most successful and non-invasive symtomatic treatment is botulinum toxin injections but microvascular decompression surgery is another therapeutic option. we report the case of a 70 years old man with bilateral hemifacial spasms and present a brief review of the literature.

Abstract: the pathogenesis of spontaneous cervical artery dissection remains unknown. infection-mediated damage of the arterial wall may be an important triggering mechanism. we describe a 21 year-old man with respiratory infection (bronchial pneumonia) which was diagnosed and treated with antibiotic few days prior to the right internal carotid artery dissection. the patient presented ischemic retinal and cerebral strokes. based on literature review, we discuss the possibility of a causal link between infection and arterial dissection.

Abstract: Espasmo hemifacial bilateral é um distúrbio de movimento raro geralmente associado à compress o vascular dos nervos faciais. Caracteriza-se clinicamente por contra es assimétricas e assíncronas da musculatura facial e por longa latência entre a instala o dos movimentos em cada hemiface. Deve ser diferenciado de outras condi es como blefaroespasmo, miocimia facial, tiques faciais, distonia oromandibular e espasmo hemimastigatório. O tratamento sintomático mais eficaz e menos invasivo consiste em aplica es de toxina botulínica mas abordagem cirúrgica de descompress o microvascular é outra alternativa terapêutica. Relatamos o caso de homem de 70 anos com espasmo hemifacial bilateral e fazemos uma breve revis o da literatura.

Abstract: spinal myoclonus is a rare movement disorder characterized by myoclonic involvement of a group of muscles supplied by a few contiguous segments of the spinal cord. structural lesions are usually the cause, but in primary spinal myoclonus the etiology remains unknown. we present the case of a 26-year-old woman with cervical spinal myoclonus in which both clinical and electromyographic findings pointed to the segment c1-c3 as the origin of the myoclonus. laboratorial examinations were normal and no structural lesion was found in magnetic resonance imaging (mri). botulinum toxin type a was injected in infrahyoid muscles and cervical paraspinal musculature. the patient remained free of symptoms for almost five months. the pathophysiology of spinal myoclonus remains speculative, but there is evidence that various possible mechanisms can be involved: loss of inhibitory function of local dorsal horn interneurons, abnormal hyperactivity of local anterior horn neurons, aberrant local axons re-excitations and loss of inhibition from suprasegmentar descending pathways.

Movement disorders induced by peripheral trauma
Nóbrega José Cláudio Marinho da,Campos Cynthia Resende,Limongi Jo?o Carlos Papaterra,Teixeira Manoel Jacobsen
Arquivos de Neuro-Psiquiatria , 2002,
Abstract: Movement disorders induced by central nervous system trauma are well recognized. However, over the last few years, attention has been drawn to the role of peripherally induced movement disorders. We describe three patients presenting respectively dystonia, tremor and choreoathetosis associated with tremor and dystonia of the body parts previously exposed to traumatic injuries. Pathophysiological mechanisms underlying these phenomena are not entirely known, but functional changes in afferent neuronal input to the spinal cord and secondary affection of higher brain stem and subcortical centers are probably involved.

Abstract: Pollen samples were collected in three different periods from 11 Melipona capixaba Moure & Camargo hives and analyzed with melissopalynological methodology. A total of 33 pollen types were identified, of which 23 genera and 15 families were identified. The following families showed the highest pollen richness: Fabaceae (7), Myrtaceae (3), Solanaceae (3), Arecaceae (2), Asteraceae (2), Euphorbiaceae (2), Melastomataceae/Combretaceae (2), Rubiaceae (2), and Sapindaceae (2). The most frequent pollen types (>45%) were Eucalyptus, which generated great similarities between the samples, except one in which the Tibouchina was predominant. Although the majority of the pollen types showed low percentage values, the results demonstrated that M. capixaba has taken advantage of the polliniferous sources available in the Atlantic Rainforest as well as in the “Capoeira” (brushwood, secondary forest) and “ruderal” (field) plants, probably implying its importance as a pollinator of the native flora and of the exotic species. 1. Introduction Melipona Illger constitutes the genus of Meliponini tribe with the biggest amount of species. It occurs in the whole neotropical region, which is the most diversified in the Amazon basin [1]. M. capixaba (popularly known as uru?u-preta or uru?u-capixaba) is endemic to the Atlantic Rainforest where it is restricted to the mountainous area of Espírito Santo State in the municipalities of Domingos Martins, Concei??o do Castelo, Venda Nova do Imigrante, Alfredo Chaves, and Afonso Cláudio embracing Pedra Azul State Park, which is protected by the government. M. capixaba was described by Moure and Camargo [2] who referred it to the Meliponini group of the Amazon region and designated by Rocha and Pompolo [3] to the same karyotype group of M. scutellaris Latreille. Experiments proved that the lack of anatomical or behavioural isolation mechanisms allowed the crossing of these species when they were brought into the same area. These observations suggest that the two species are capable of forming fertile hybrids [4]. The fact that two ecologically different species of stingless bees, separated by more than 300?km, could still cross when placed in the same area suggests that there has not been any pressure to develop reproductive isolation [4]. However, M. capixaba is mentioned on the list of Endangered Brazilian species (Normative Instructions no. 3, May 27th 2003, Ministry of Environment) because its original habitat has been almost completely fragmented to make room to pastureland, coffee (Coffea sp), and Eucalytus sp cultivars.

Abstract: objective: the objectives of the present study were to determine the prevalence of potentially pathogenic microorganisms that indicate the hygienic and sanitary conditions of human milk samples collected at a human milk bank. methods: three hundred and thirty eight (338) samples of human milk collected from a milk bank in a maternity in the municipality of goiania, in the state of goias, brazil were submitted to microbiological analysis. the latter were plated on mcconkey agar according to the type of bacteria. among the total number of samples collected, 194 consisted of raw milk and the remaining 144 were pasteurized milk. results: the presence of staphylococcus spp., streptococcus spp., yeasts and molds, and enterobacteriaceae was verified in the raw milk samples. staphylococcus aureus were isolated in 10 (5.2%) samples, staphylococcus epidermidis in 28 (14.4%) samples, streptococcus spp. in three (1.6%) samples, yeasts and molds in 43 (22.2%) and enterobacteriaceae in 49 (25.3%) samples. in a hundred and forty four (144) samples which underwent thermal treatment staphylococcus aureus was detected in five (3.5%) samples, staphylococcus epidermidis in 15 (10.4%), staphylococcus lugdenensis in two (1.4%), streptococcus spp. in four (2.8%), yeasts and molds in 37 (25.7%), and enterobacteriaceae in nine (6.3%). conclusions: analysis indicated a high degree of contamination in raw human milk, and as for the pasteurized milk, despite elimination of the great majority of potentially pathogenic microorganisms, the percentage of yeasts and molds was higher than in raw milk, demonstrating that a lower degree of initial contamination would be necessary for pasteurization to be an efficient means of microbiological control.
Elecciones en anticoncepción quirúrgica: una mirada sobre la relación entre la técnica y la persona
del Río Fortuna,Cynthia;
Runa , 2009,
Abstract: contraceptive practices can be anthropologically approached as technical activities taking place in people's everyday life. to study their choice we must consider the wider social and symbolic context, involving "non-technical" aspects. based on an ethnographic study carried out in an obstetrician public service in buenos aires, this article addresses the relationship between technique and person-building in the case of female surgical contraception from the perspective of health professionals. we examine the practices and representations by which these professionals regulate the access to that practice, which allows us to identify ways of biomedic definition and intervention of female bodies.
