Arquivos de Neuro-Psiquiatria , 1992, DOI: 10.1590/S0004-282X1992000400007
Abstract: the etiology of 200 cases of peripheral neuropathies was studied taking into account the most affected age ranges, as well as the sex and occupation of the patients. the age ranges of our patients for the polyneuropathies consequent to alcoholism, for diabetic polyneuropathy, for guillain-barré syndrome and for hereditary sensorimotor neuropathies were 20 to 50 years, 10 to 70 years and 0 to 30 years. the age range of patients with leprosy and nerve injury was 20 to 50 years, and more frequently up to 30 years. alcoholic and diabetic polyneuropathies predominantly affected males, whereas injury to the median nerve and multiradiculopathies mainly affected women. approximately 1/3 of the alcoholic polyneuropathies affected laborers. inactivity was reported by 1/3 of the patients with diabetic polyneuropathies, by 25% of the patients with polyneuropathies consequent to alcoholism and by 24% of the patients with undefined polyneuropathies.

Marques Júnior, Wilson;Barreira, Amilton Antunes;Herrera, Ronaldo Francisco;
Arquivos de Neuro-Psiquiatria , 1992, DOI: 10.1590/S0004-282X1992000400005
Abstract: the present study was undertaken to evaluate the influence of clinical examination and complementary tests on the diagnosis of peripheral neuropathies. most of the patients (81.8%) were submitted to laboratory tests, 47.4% were submitted to electromyography, and 22.5% to biopsy. a syndromic diagnosis was made in 99.0% of the patients, topographic diagnosis in 98.6%, and etiological diagnosis in 73.2%. an average of 4.8 tests per patient were requested and 36 of the 93 different tests always gave normal results. the importance of the findings is discussed.
Diagnóstico das neuropatias periféricas diagnósticos sindr?micos, topográficos e etiológicos: syndromic, topographic and etiological diagnoses
Marques Junior, Wilson;Herrera, Ronaldo Francisco;Trade, Emília Sim?o;Barreira, Amilton Antunes;
Arquivos de Neuro-Psiquiatria , 1992, DOI: 10.1590/S0004-282X1992000400006
Abstract: a retrospective study was conducted to identify the syndromic, topographic and etiological diagnoses made for a group of 209 patients with peripheral neuropathies. anamnesis and clinical-neurological examination were of fundamental importance for the syndromic and topographic diagnoses. electromyography played an important role, especially with respect to the topographic diagnoses. the etiological diagnoses depended on additional complementary tests such as: blood glucose levels and blood glucose tolerance test; nutritional evaluation; family evaluation; nerve, skin, pharynx and maxillary sinus biopsies; qualitative tests for the presence of porphyrins in urine; urinary levels of delta-aminolevulinic acid and porphobilinogen; and radiological examinations. the most frequently encountered polyneuropathies were those consequent to alcoholism or to diabetes, and those of the acute demyelinating inflammatory or hereditary type. among the cases of mononeuropathy, the most frequently diagnosed conditions were carpal tunnel syndromes, traumatic injury to the vii cranial nerve, and trigeminal neuralgias. leprosy, brachial plexus injury and thoracic outlet compression syndrome predominated among the multineuropathies.

Abstract: Background: Inpatient rehabilitation has been traditionally employed in developed countries, while in developing countries, outpatient rehabilitation is the rule. The purpose of this study was to compare the patterns of recovery of upper extremity (UE) function, global impairment and independence in activities of daily living (ADL) during the first month after ischaemic stroke in inpatient (United States) and outpatient (Brazil) rehabilitation settings. Design and Methods: This is a prospective cohort comparison study. Twenty patients from each country were selected using identical inclusion criteria. The study measures employed were the UE portion of the Fugl-Meyer scale, the Action Research Arm test, the National Institutes of Health Stroke Scale and Barthel Index. Changes from baseline to the end of treatment, efficiency and effectiveness of each treatment were compared. Results: Both populations exhibited significant improvement between the first and second evaluations in the four outcome scales (P <0.0001). There were no differences between the two rehabilitation settings on any of the four dependent measures (P>0.05). Conclusions: Substantially different treatment approaches after ischaemic stroke led to similar results in UE function, global impairment and ADL. Further studies in larger populations should be performed in order to confirm the present results.

Almeida, Fábio Henrique Souza;Okano, Nelson;Vargas, Eulógio Corrales;Ferreira-Santos, Ruy;Sato, Takassu;Barreira, Amilton Antunes;
Acta Cirurgica Brasileira , 2000, DOI: 10.1590/S0102-86502000000600016
Abstract: a miastenia gravis é uma doen?a auto-imune caracterizada por auto-anticorpos contra receptores nicotínicos de acetilcolina da placa neural. o tratamento clínico básico para as formas generalizadas é feito com drogas anticolenesterásicas, mas em algumas fases podem ser necessários outras modalidades de tratamento, tais como a corticoterapia e a plasmaferese. o tratamento cirúrgico, a timectomia, é uma forma de abordar a causa base da doen?a e tem resultados bastante encorajadores, visto que é atribuída ao timo a produ??o dos auto-anticorpos. apresentamos neste trabalho o quadro clínico, os resultados cirúrgicos e as altera??o anátomo-patológicas dos 90 casos estudados.

Arquivos de Neuro-Psiquiatria , 2002, DOI: 10.1590/S0004-282X2002000400009
Abstract: the blink reflex latencies and cephalometric indexes were analysed in 30 male volunteers from three different races, 10 white, 10 black, and 10 oriental. ages ranged from 15 to 59 years, height from 1,60 to 1,80 m, and weight from 60 to 80 kg. blink reflexes were obtained after unilateral electric stimulation of the supraorbital nerve for quantitative analysis of 3 responses, early ipsilateral (r1), late ipsilateral (r2i) and late contralateral (r2c), obtained from the orbicularis oculi muscle. cephalometric indexes were calculated by multiplying the ratio between the longer transverse and the longer sagital head diameters by 100. the r1, r2i and r2c latencies were consistent with other published papers revealing no differences between the different racial groups. the mean of the cephalometric indexes of each group were consistent with respective racial characteristics. this study revealed that there are no differences between r1, r2i and r2c latencies in the 3 different studied races.
Cytogenetics studies in thirteen Brazilian species of Phaneropterinae (Orthoptera: Tettigonioidea: Tettigoniidae): main evolutive trends based on their karyological traits
Ferreira, Amilton;Mesa, Alejo;
Neotropical Entomology , 2007, DOI: 10.1590/S1519-566X2007000400003
Abstract: the thirteen species of phaneropterinae here studied can be arranged in four different groups according to their basic karyological traits. all of them share the same kind of chromosomal sex determining mechanism with x0(male) and xx(female). the x chromosome differs among species and always appears heteropycnotic during prophase i, it is the largest in the set and segregates precociously during anaphase i. among the species, the karyotypes varies in fundamental number between 31 to 21. the meaning of these significant changes in the karyotypes in relation to the phylogeny within some large taxonomic group of species is discussed.
Cytogenetics studies in Brazilian species of Pseudophyllinae (Orthoptera: Tettigoniidae): 2n(♂)=35 and fn=35 the probable basic and ancestral karyotype of the family tettigoniidae
Ferreira, Amilton;Mesa, Alejo;
Neotropical Entomology , 2010, DOI: 10.1590/S1519-566X2010000400019
Abstract: the karyotypes of five species of brazilian pseudophyllinae belonging to four tribes were here studied. the data available in the literature altogether with those obtained with species in here studied allowed us to infer that 2n(♂)=35 is the highest chromosome number found in the family tettigoniidae and that it is present in species belonging to pseudophyllinae, zaprochilinae and in one species of tettigoniinae. in spite of that all five species exhibit secondary karyotypes arisen surely by a mechanism of chromosomal rearrangement of centric fusion, tandem fusion and centric inversion types from those with 2n(♂)=35 and fn=35, they share some common traits. the x chromosome is submetacentric (fn=36), heteropicnotic during the first prophase, the largest of the set but its size is rather variable among the species and the sex chromosomal mechanism is of the xo( ♂ ), xx( ♀ ) type. the chromosomal rearrangements involved in the karyotype evolution of the pseudophyllinae and its relationship with those of the family tettigoniidae are discussed and we propose that the basic and the ancestral karyotype of the tettigoniidae is formed by 2n(♂)=35, fn=35 and not by 2n(♂)=31, fn= 31, as usually accepted.
