Os autores fazem uma revisão da enterobíase com uma visão clínica, com maior ênfase no diagnóstico e apresentação de novas opções terapêuticas desta parasitose intestinal

Appendicitis and enterobius vermicularis

To evaluate the appendicitis due to Enterobius vermicularis. Appendices were removed and histopathological examination was carried out. The samples were obtained from patients admitted in Imam khomeini hospital at Ahvaz city, capital of Khouzestan Province, Southwestern part of Iran. 1253 appendices were examined in order to elucidate possible relationship between the incidence of Enterobius vermicularis and the origin of inflammation.Main outcome: Assesment of the appendicitis due to Enterobius vermicularis. Nine out of 1253 cases [0.7%] were infected with Enterobius vermicularis, including 5 female and 4 male at the age of 8-36 years. During the operation in two female cases, ovarian cysts were revealed at the same time. Existence of Enterobius vermicularis in appendicitis can cause the symptom and even inflammation of appendicitis

Combined infection by enterobius vermicularis and cryptosporidium protozoan in appendix

Acute appendicitis caused by combined infection of Enterobius vermicularis and cryptosporidium protozoa in a normally looking appendix described. The patient is a 9-years-old immunocompetent boy who was admitted with acute abdomen and vomiting of one day duration. We believe that this is the first case in the literature that described such a combination. We report this case to increase the awareness of the physicians as well as the pathologists in diagnosing of cryptosporidiosis

Enteroparasitos en niños residentes en zona rural del Partido del Carmen de Patagones: Provincia de Buenos Aires, Argentina / Enteroparasites in children living in rural areas at the Partido de Carmen de Patagones: province of Buenos Aires, Argentina

Como parte del programa de atención primaria de la salud (APS) del año 1996, y en virtud que no existían datos epidemiológicos referidos a enteroparásitos hallados en niños de 0 a 14 años, residentes en una zona rural del Partido de Carmen de Patagones, Provincia de Buenos Aires, es que se realizó el presente estudio epidemiológico descriptivo. Se estudiaron 210 niños a los que se les efectúo un estudio parasitoscópico seriado de materia fecal y mucus anal. Los resultados mostraron que el 60,5 por ciento de la población estudiada era portadora de algún parásito intestinal. El monoparasitismo hallado fue de 67 por ciento, mientras que 33 por ciento restante presentó entre 2 y 5 formas parasitarias. El espectro parasitario fue el siguiente: entamoeba coli 31,5 por ciento, giardia lamblia 24,7 por ciento; enterobius vermicularis 18 por ciento; hymenolepis nana 10,4 por ciento; blastocystis hominis 10,4 por ciento; 10,3 por ciento; chilomastix mesnili 2,5 por ciento; entamoeba hystolytica 0,9 por ciento y trichuris 0,5 por ciento. La distribución parasitaria en los distintos sectores estudiados fue en general homogénea excepto para H. nana la cual presentó una prevalencia más altas en zonas de riesgos con relación a la zona seca. Los resultados obtenidos fueron comunicados a las autoridades sanitarias correspondientes

Abdominal wall abscess caused by enterobius vermicularis

A seven-year-old boy presented with abdominal wall abscess due to Enterobius vermicularis. Gastro-intestinal tract and overlying skin were normal. This report is to our knowledge the first abdominal wall abscess due to oxyuriasis. Possible hematogenous mode of involvement of the liver and lung may further be supported by the present case

Enterobiasis en escolares de Ciudad Bolívar, Estado Bolívar, Venezuela / Enterobiasis in schoolchildren from Ciudad Bolívar, Estado Bolívar, Venezuela

Enterobius vermicularis is a nematode with a peculiar biological cycle, thus requiring a special diagnostic technique. In order to determine the prevalence of E. vermicularis infection among schoolchildren in Ciudad Bolívar, Venezuela, 282 children aged 5 - 14 years old were evaluated between november 1995 and august 1996 by the Graham technique (three perianal swabs with adhesive cellulose tape). The prevalence of enterobiasis in the studied children was estimated 19,1 percent (54/282). There was no difference between sexes (p>0,05), but there was a difference between ages (x² = 13,8; 1.g.= 4), being the infection more frequent between 5 and 8 years. Symptoms were observed in 90,7 percent of the schoolchildren. Anal pruritus was the most common clinical finding (81,6 percent). Other less frequent manifestations were enuresis (28,6 percent) and vulvitis in girls (26,1 percent). This intestinal parasitosis occurs with high frequency among schoolchildren in Ciudad Bolívar with characteristic and identifiable symptoms in most cases. The Graham method must be used for its diagnosis. This test is not routinely performed in our laboratories unless specifically requested by the attending physician

Oxyuriasis pélvica / Pelvic oxyuriasis

El enterobius vermicularis, es un parásito que comúnmente infesta el lumen intestinal, en raras ocasiones es posible encontrarlo en otras localizaciones. Se presenta caso clínico, en el que se encontraron granulomas por enterobius vermicularis en serosa de trompa uterina, que se habrían instalado allí por fístula rectal secundaria a perforación por un dispositivo intrauterino. Se describen las lesiones histopatológicas, sus implicancias clínicas y revisión de la literatura

Enterobius vermicularis in cerebrospinal fluid

Enterobius vermicularis is a nematod of large intestine in man. Extra intestinal localization of this parasite is rare. A 60 year old man was admitted to the hospital with the clinical manifestation of meningitis. In laboratory examination of cerebrospinal fluid [C.S.F], the appearance was red,albumin level was high and the glucose showed normal value. Haematoxylin and Eosin stained slide prepared from the precipitation revealed adults, larvae and ova of Enterobius vermicularis. This is the first report of Enterobius vermicularis in cerebrospinal fluid

Algunos aspectos epidemiológicos de las infecciones por enterobius vermicularis en pacientes atendidos en consultorios de atención primaria del sector norte de Santiago 1995 / Some epidemiological aspects of enterobius vermicularis infections in patients attending at primary care centers of north section at Santiago, Chile 1995

During 1995, we examined 2,666 Graham's tests (five perianal swabs with adhesive cellulose tape) prescribed to ambulatory patients attended in 14 public outpatient clinics and four hospitals from the north section of Santiago. The infection rates found by age groups were the following: 6,1 percent in infants (< 2 years old), 20,9 percent in pre-schoolchildren (2 < 6 years old), 35,2 percent in elementary schoolchildren (6 < 15 years old) and 15,2 percent in adults (> 15 years old). Similar percentages of E. vermicularis infections were observed in females and males patients. Frequency of infection in each month of the year varied between 17,4 and 26,8 percent, with no seasonal variation. This study and previous surveys are stressing that E. vermicularis is the most frequent helminthic agent found in Chile, specially in elementary school children.

Parasitic infection among children living in two orphanages in Cairo

Children living in institutions as orphanages are more exposed to intestinal parasitism, since crowding and behavioral pattern contribute greatly to the spread of parasitic infection. The present study was conducted on 100 children living in Ain-Shams and El-Mowassa orphanages, Cairo. Twenty children living under appropriate health conditions were studied as controls. Ages of both groups ranged from 6 to 12 years. The results of this study revealed that 69/100 [69%] orphanage children were positive for parasitic infection, while 8/20 [40%] control subjects were positive for parasitic infection, the difference was statistically significant. Enterobius vermicularis was the commonest parasite among both groups. Other parasitic infections detected were Giardia lamblia, Entamoeba histolytica, Hymenolepis nana and Entamoeba coli with a prevalence of 10%, 9%, 2% and 9%, respectively, in the study group compared with 15%, 10%, 0% and 5% in the control group. The differences were statistically not significant. Cryptosporidium oocysts were not detected in both groups

Vulvovaginitis en niñas causada por enterobius vermicularis / Vulvovaginitis in girls caused by enterobius vermicularis

La vulvovaginitis es un padecimiento que representa una preocupación para la paciente, sus familiares y en ocasiones para el propio médico, ya que en algunos casos son resistentes al tratamiento habitual. En una revisión de 6 555 enfermas atendidas en consulta externa del Departamento de Enfermedades Infecciosas y Parasitarias del Instituto Nacional de Pediatría, se encontró que s.3% cursaba con vulvovaginitis y 20% de estas últimas presentaba enterobiasis intestinal simultánea. En otro grupo 297 pacientes con enterobiasis intestinal pura, 10% cursaba con vulvovaginitis. En ningún caso se encontró infección de las vías urinarias secundarias a vulvovaginitis por enterobiasis. El tratamiento con un antiparasitario específico contra Enterobius vermicularis más aseo genital con agua y jabón basta para lograr la curación
