Abstract: Introducción: la toxoplasmosis es una zoonosis frecuente, causada por un parásito intracelular obligado: el toxoplasma gondii. Es la causa más frecuente de uveítis posterior y puede provocar secuelas oftalmológicas graves. Objetivo: caracterizar el comportamiento clínico-epidemiológico, así como la evolución y las principales complicaciones de pacientes atendidos por toxoplasmosis ocular activa en el Centro Oftalmológico de Pinar del Río. Material y método: se realizó un estudio de tipo observacional, descriptivo, de corte transversal, en pacientes con diagnóstico de toxoplasmosis ocular activa, en el período de tiempo comprendido entre enero 2011 y octubre del a o 2012. El universo estuvo constituido por la totalidad de pacientes que acudieron a consulta, con el diagnóstico de toxoplasmosis ocular (34), y la muestra por aquellos que presentaron la forma activa de la infección (14). Resultados: predominaron los pacientes en las edades comprendidas entre los 30 y 39 a os de edad, con un ligero predominio del sexo femenino. El síntoma más frecuente fue la visión borrosa, la lesión se presentó fundamentalmente en la zona I de la retina. Las lesiones necrotizantes de retinocoroiditis toxoplásmica, acompa adas de vitritis de variable intensidad, fueron el hallazgo oftalmológico más frecuente, y predominan los pacientes con mejor agudeza visual por debajo de 0,3 después del tratamiento. El edema macular y la hipertensión ocular resultaron las complicaciones más frecuentes. Conclusiones: las características clínicas de los pacientes coincidieron con lo descrito en la literatura. El grado de afectación visual estuvo relacionado con la localización de las lesiones y las complicaciones. Introduction: toxoplasmosis is a frequent zoonosis caused by an obligate intracellular parasite: toxoplasma gondii. The most frequent cause is posterior uveitis and can provoke severe ophthalmic sequels. Objective: to characterize clinical and epidemiological behavior, natural history and main complications of patients suffering from active-ocular toxoplasmosis at the Ophthalmologic Center in Pinar del Rio province. Material and method: an observational, descriptive and cross sectional study was conducted in patients having the diagnosis of active-ocular toxoplasmosis, during January 2011 and October 2012. The target group was comprised of the totality of patients attending to the center with the diagnosis of ocular toxoplasmosis (34), and the sample included those presenting the active form of infection (14). Results: patients between 30 and 39 years old prevailed, with a slight

Revista Cubana de Medicina General Integral , 1996,
Abstract: Se ofrece una revisión teórica actualizada sobre la terapia, la prevención y el control de la toxoplasmosis a partir de la literatura revisada en las bases de datos MEDLINE, LILACS y la de Literatura Cubana de Medicina de los a os 1989 a 1995, también se incluyen algunos clásicos propios de la temática localizados en los órganos de información del Sistema Nacional de Información de Ciencias Médicas. Se tratan otros aspectos de interés como el modo de transmisión, los hospederos (definitivos e intermediarios) y las manifestaciones clínicas más notables. Se destaca la importancia de realizar el examen parasitológico a nivel primario de salud y con carácter masivo a partir del proceso de captación de la embarazada y de llevar a cabo el seguimiento, con vistas a detectar tempranamente la presencia del parásito o la enfermedad y evitar las consecuencias negativas que esta conlleva.

Abstract: untreated acute toxoplasmosis among pregnant women can lead to serious sequelae among newborns, including neurological impairment and blindness. in brazil, the risk of congenital toxoplasmosis (ctox) has not been fully evaluated. our aim was to evaluate trends in acute toxoplasmosis prevalence from 1998-2005, the incidence of ctox and the rate of mother-to-child transmission (mtct). a cross-sectional study was undertaken to dentify patients who fit the criteria for acute toxoplasmosis during pregnancy. exposed newborns were included in a historical cohort, with a median follow-up time of 11 months, to establish definite diagnosis of ctox. diagnoses for acute infection in pregnancy and ctox were based on european research network on congenital toxoplasmosis criteria. in 41,112 pregnant women, the prevalence of acute toxoplasmosis was 4.8/1,000 women. the birth prevalence of ctox was 0.6/1,000 newborns [95% confidence interval (ci): 0.4-0.9]. during the follow-up study, 12 additional cases were detected, increasing the ctox rate to 0.9/1,000 newborns (95% ci: 0.6-1.3). among the 200 newborns exposed to toxoplasma gondii,there were 37 babies presenting diagnostic criteria of ctox, leading to an mtct rate of 18.5% (95% ci: 13.4-24.6%). the additional cases identified during follow-up reinforce the need for serological monitoring during the first year of life, even in the absence of evidence of congenital infection at birth.

Abstract: the occurrence of toxoplasma antibodies in domestic outpatient cats in the city of s?o paulo was evaluated using the indirect immunofluorescence assay. a total of 248 blood samples obtained from male and female cats seen at the veterinary teaching hospital at the university of s?o paulo between february 1996 and january 1997 were tested. of these, 17.7% were positive, with a 64 titer being detected in most animals. the frequence of toxoplasma antibodies was significantly higher in older cats, those fed raw meat and those with free access to the outdoor environment. there was no significant difference in reactivity between males and females. we conclude that diet and free access to the outdoor environment were equally important as predisposing factors to the risk of toxoplasma infection.

Abstract: La toxoplasmosis ocular es una enfermedad producida por el parásito toxoplasma gondii. Es la causa más frecuente de uveítis posterior, es una enfermedad de distribución universal, al menos 500 millones de personas están infectadas en todo el mundo, ocasionando disminución de la visión y ceguera en muchas de ellas. Por tal motivo, realizamos una revisión actualizada sobre, la situación actual a nivel mundial, la historia de la enfermedad, la prevención, formas clínicas y el control de la toxoplasmosis. Se tratan otros aspectos de interés como el modo de transmisión, los hospederos (definitivos e intermediarios) y las manifestaciones clínicas más notables. The ocular toxoplasmosis is an illness caused by Toxoplasma gondii parasite. It is the most frequent cause in posterior uveitis, and it spreads worldwide since at least 500 million people are infected in the entire world, causing decrease of vision and blindness in many of them. This is the reason why we made a literature review, the current situation worldwide, the history, the prevention, the clinical forms and the control of toxoplasmosis. Other interesting aspects were the channel of transmission, the hosts (intermediary and final) and the most remarkable clinical manifestations.

Journal of Research in Medical Sciences , 2002,
Abstract: Introduction. Seronegative pregnant women are at risk of toxoplasmosis and its fetal abnormalities (congenital toxoplasmosis). Planning for control of disease needs to determine current status of immunity in premariage women. Methods. This cross-sectional study was done on 273 premarriage women in Amin medical center (Iran, Isfahan - summer 2000). Serum antitoxoplasma antibodies were measured by immunofluorescence method. Results were analyzed with SPSS software using Chi Square, Mantel-Haenszel and Logistic Regression statistical methods. Results. Mean age of study participant was 20.3±4.13 (Mean ± SD) years. Eighty percent of them were high school graduated and lower. Fiftysix percent of them lived in outskirts and marginal sites of the city. Prevelance of seronegative women was 56.1%. No significant relationship between seropositivity and education, job or age was found (P > 0.05). Women living in marginal sites of the city had 1.8 times more chance for seropositivity (P=0.01, OR= 1.87, CI95%(OR) = 1. 16 - 3.05). Discussion. According to early marriage and high prevalence of seronegative women, risk of infection during pregnancy period is considerable so it would be dersired to plan and perform educational programs for prevention of infection during pregnancy.

Abstract: Report a case of a male patient with a macular scar compatible with ocular toxoplasmosis (OT) in right eye (RE) and review the relevant literature on this disease. A patient, who attended for a routine contact lens follow up, presented with amblyopic exotropia without any ocular disease. Best-corrected visual acuity of the affected eye was 20/40 with constant and mono-fixation exotropia. Ophthalmoscopic assessment revealed a macular scar compatible with OT. OT is the leading cause of infection in the posterior segment. Inactive cases could be asymptomatic and diagnosis requires a complete eye examination, providing a correct diagnosis and patient management.
