Arquivos de Neuro-Psiquiatria , 1990, DOI: 10.1590/S0004-282X1990000400004
Abstract: the authors describe the epidemiological findings related to human taeniasis and cysticercosis, and swine cysticercosis in two small rural communities, postinho (p) and tigre (t), of south brazil. the prevalence of epilepsy was 2.04% (p) and 2.25% (t). the prevalence of neurocysticercosis was 0.47% (p) and 0.93% (t), and prevalence of swine cysticercosis was 12.8% (p) and 27.8% (t). taenia sp. infestation wis detected in 4.3% (p) and 4.6% (t) of stool examinations. the hyperendemic human taeniasis and cysticercosis and swine cysticercosis seems to be related to poor hygienic habits of the population, and the free access to human excreta by the pigs.
Scorpions, state of Bahia, northeastern Brazil  [PDF]
Porto, T. J.,Brazil, T. K.,Lira-da-Silva, R. M.
Check List , 2010,
Abstract: We report herein an updated and commented list of scorpions occurring in state of Bahia, northeastern Brazil.Data comprising a period of 100 years (1908-2008) were obtained from seven major Brazilian collections. Twenty eight specieswere identified and grouped in seven genera (Bothriurus Peters, 1861, Ananteris Thorell, 1891, Isometrus Ehrenberg, 1828,Physoctonus Mello-Leit o, 1934, Rhopalurus Thorell, 1876, Tityus C.L.Koch, 1836 and Troglorhopalurus Louren o, Baptista andGiupponi, 2004) and two families (Bothriuridae Simon, 1880 and Buthidae C.L. Koch, 1837). This new list increases in 50 % theknown scorpiofauna of Bahia, which now represents approximately 22 % of the Brazilian species, recorded in all biomes andphytophysiognomies from the coastal zone to high altitude areas (3-1,268 m). Seven species are endemic to Bahia and threeof them could be included in the Brazilian National Red List, which would promote action plans towards their conservation.

Abstract: multiple sclerosis (ms) is an autoimmune, demyelinating and degenerative disease that affects the central nervous system. its prevalence and clinical aspects vary according to the continent considered, being more frequent in caucasians and young individuals aged 20 to 40 years. epidemiological data from brazil show that prevalence is variable, being more frequent in the southern and southeastern areas of the country, rather than in the northern and northeastern areas. the purpose of this paper is to describe ms clinical and epidemiological features in the state of bahia, in the brazilian northeastern region. thus, we held a cross-sectional study over the period from february to may, 2005, in the multiple sclerosis patient support center ("núcleo de apoio aos pacientes com esclerose múltipla") of bahia, which included all patients with a diagnosis of ms seen over this period of time. a total of 121 patients were investigated, being 80.2% females (female:male ratio=4:1), with higher frequency in mulatto individuals (64%), and the relapsing-remitting type (91.3%). most patients (68.7%) had mild ms, and blacks were prone to worse prognosis compared to other patients.
The Barreiras Group in the Northeastern coast of the State of Bahia, Brazil: depositional mechanisms and processes

Abstract: the barreiras group is a miocene to lower pleistocene continental terrigenous sedimentary deposit exhibiting a large occurrence along the brazilian coast. in the conde region, located in the northeastern part of the state of bahia, the sedimentological characteristics of these sediments are indicative of a deposition as gravelly and sandy bed load in braided fluvial systems, related to alluvial fans, under an arid to semi-arid climate. the basal portion of the group is dominated by a gravelly-sandy lithofacies deposited by debris flows and pseudoplastic debris flows, with lesser occurrences of subaqueous deposits, characterizing a proximal fluvial system deposition. the upper portion is made up of gravelly-sandy sediments that include subaqueous, debris flows and pseudoplastic debris flows deposits. they suggest deposition in a more distal zone as indicated by the larger occurrence of subaqueous deposits and the presence, though rare, of downstream-accretion macroforms. besides the climate control, deposition of the barreiras group was strongly influenced by the intraplate tectonism, which has been affecting the south america platform since the middle miocene, when neotectonism began in brazil.

Abstract: the calanoid copepod euchaeta paraconcinna fleminger, 1957 is reported from camamu bay, state of bahia, northeastern brazil (14o02'49"s; 38o52'58"w). three females were collected by vertical hauls with a plankton net of 200 μm mesh size. this is a new record for this species in northeastern brazil.

Abstract: neurocysticercosis (ncc) is a common parasitic disease in our region, presenting diversity of neurological symptoms and signs. the present study has as primary objective an evaluation of the ncc's clinical and epidemiological profile within bahia state, by means of a prospective study of 220 patients diagnosed from march 1988 to march 1999, with a follow-up of six months. exams, such as computed cranial tomography scan (ct), cerebral spine fluid (csf) and electroencephalogram (eeg), were accomplished in three distinct moments of these patients' evolution: at starting or diagnostic point (zero time), at after-intervention period (one month after treatment), and at control period (six months after treatment).

Abstract: wuchereria bancrofti in pernambuco was first documented in 1952 (azevedo & dobbin 1952), and since then it has been reported in surveys carried out in selected areas of recife. several surveys were carried out from 1981 to 1991 by sucam. in the 1985 sucam's report the disease is considered under control. the cpqam filariasis research program was established in 1985 and a filarial survey was carried out in the town of olinda, greater recife. in order to verify the real epidemiological situation, a study was conducted in the city of recife. 21/36 of the special zones of social interest (zeis), were randomly selected for the present study. from 10,664 persons screened, 683 were positive and the prevalence rate for microfilaraemia (mf) varied from 0.6% to 14.9%. a mean mf prevalence of 6.5%, showed that the infection occurs in a wide geographic distribution in greater recife and that the intensity of transmission is a real and potential threat to public health in affected communities. mf rate among males and females differed significantly. due to the rapid increase in population, unplanned urban settlements, poor sanitary facilities and the favorable geographical conditions to the development of the vector, filariasis may actually be increasing in recife.

Abstract: triatoma juazeirensis, a new triatomine species from the state of bahia, northeastern brazil, is described. the new species is found among rocks in sylvatic environment and in the peridomicile. type specimens were deposited in the entomological collection of oswaldo cruz institute-fiocruz, museum of zoology of university of s?o paulo, and florida museum of natural history. t. juazeirensis can be distinguished from the other members of the t. brasiliensis species complex mainly by the overall color of the pronotum, which is dark, and by the entirely dark femora.

Abstract: Neurocysticercosis is the most common parasitic infection of central nervous system, itsfrequency in developing countries is described by many case studies as high, howeverthere are not strategies to impact frequency of the disease and optimal treatmentregimens. This is a review article which describes the epidemiological, clinical,diagnostic and therapeutic aspects of neurocysticercosis in pediatrics.RESUMEN:La neurocisticercosis es la infección parasitaria más frecuente del sistema nerviosocentral. Su frecuencia de presentación en los países subdesarrollados está descrita pormuchos estudios de casos como alta, sin embargo no hay estrategias que impactenpositivamente la variabilidad de frecuencia de presentación; carece de pautasterapéuticas óptimas y se ha fallado en las estrategias de prevención y promoción.Se realiza una revisión temática y se describen aspectos epidemiológicos, clínicos,diagnósticos y terapéuticos de la neurocistercosis en pediatría.
