Manifestações clínicas de pacientes com diagnóstico de neurocisticercose por tomografia computadorizada

Abstract

RESUMO -Foram estudados através de entrevistas semi-estruturadas pacientes submetidos a tomografia computadorizada de crânio em um centro de diagnóstico por imagem na cidade de Lages. Realizaram-se entrevistas em 42 pacientes positivos para cisticercose cerebral e 57 pacientes sem alterações patológicas ao referido exame. Os pacientes com diagnóstico positivo relataram com maior frequência manifestações clínicas relacionadas à neurocisticercose, sendo este fato mais marcante para o sexo feminino, com exceção de convulsões, que ocorreram mais no sexo masculino (19,05%) que no feminino (7,14%). A maior percentagem de diagnósticos de formas inativas (83,33%) e o relato de sintomas em um tempo mais prolongado entre os entrevistados positivos sugerem que o problema é antigo.PALAVRAS-CHAVE: cisticercose, neurocisticercose, tomografia computadorizada. Clinical manifestations in patients with computerized tomography diagnosis of neurocysticercosisABSTRACT -A survey was conducted in the urban area of Lages using patients who had been submitted to a computed tomography of the skull in the period of March-December, 1996, for different reasons. Forty-two patients with a provisional diagnosis of neurocysticercosis, and 57 negatives were personally interviewed by one of the authors (Pfuetzenreiter), using a semi-structured procedure. More individuals with a provisional diagnostic of neurocysticercosis reported clinical manifestations related to this infection than those found negative. This difference is more marked among women, except in relation to convulsions, more frequently reported by men (19.05%) than by women (7.14%). The greater percentage of inactive forms (83.33%) and a longer history of perceived symptoms among those positives suggest that the condition is not new.

Aspectos clínico-epidemiológicos da neurocisticercose no Brasil: análise crítica

“…Sexo: no geral, a NCC comprometeu mais o sexo masculino (51-80%; Md= 63%) 1,[9][10][11]13,16 . Entretanto, houve envolvimento mais frequente do sexo feminino (53-75%; Md= 73%) naqueles pacientes que apresentaram manifestações graves 1,[17][18][19][20] . Nas crianças, não houve diferença significativa entre meninos e meninas 1,12,15 .…”

Perfil clínico-epidemiológico de pacientes com neurocisticercose atendidos no Hospital Universitário Regional de Maringá, Paraná, Brasil

“…Este mesmo padrão foi observado em outros estudos no Brasil 20,21 e no exterior 22,23 . Embora Agapejev 12 tenha constatado que, no Brasil, a NCC sociada ao EEG em apenas três casos.…”

Epidemiologic pattern of patients with neurocysticercosis diagnosed by computed tomography in Curitiba, Brazil

“…Whereas in previous study, the hypodense processes (13 or 5.5%) and both forms, hypodense and calcifications (3 or 1.3%) were found in 236 cases of neurocysticercosis diagnosed patients in Curitiba 6 . NCC cases were mostly from urban areas in epidemiological studies based on computed tomographies, such as a previous study in Curitiba (78.40%) 6 , in Maringa (93.75%) 7 , in Lages (100%) 8 and in Cianorte (95%) 13 . Although most of suggestive neurocysticercosis patients were resident in Curitiba (78.02%), is not possible to confirm when and where the infection occurred, since the disease has a chronic character and the calcification process completed over 5 years on average 15 .…”

“…An overall of 4,040 human cases of cysticercosis were notified in the Parana state from 1980 to 2000 10 . In studies using computed tomographies in other regions of Brazil the prevalence was 0.19% in Baixada Fluminense -Rio de Janeiro Female has been the most predominant for the NCC suggestive cases [5][6][7][8]12,13 . We found 70.3% (64/91) women and 29.6% (27/91) men among NCC patients, indeed represent 9.4% (64/677) and 8.1% (27/332) among entire female and male studied population, respectively.…”

“…NCC has traditionally been a parasitic disease of rural settings, related to poor personal hygiene habits and sanitary structure conditions 4 . In contrast, neurocysticercosis has been more recently recognized in urban areas, even when basic sanitation facilities are provided 2,[5][6][7][8] . Curitiba is the capital of Parana state and currently the seventh most populated capital in Brazil, with 1,828,092 habitants within city and a metropolitan area of 26 cities and 3,172,357 people 9 .…”
