Ophthalmological findings in patients suspected with COVID-19 at a tertiary hospital in Pernambuco, Brazil / Achados oftalmológicos em pacientes com suspeita de COVID-19 atendidos na triagem do HC-UFPE

ABSTRACT Purpose: This study evaluated the frequency of the most common ophthalmological, neurological, and systemic findings in symptomatic patients seen at a COVID-19 screening service at Hospital das Clínicas - Universidade Federal de Pernambuco. Methods: A total of 104 patients under clinical suspicion of SARS-CoV-2 infection underwent medical evaluation through an ophthalmological and systemic symptoms survey. All participants selected for the study underwent COVID-19 RT-PCR testing. Results: The mean age was 38.8 years, with 44.23% between 31 and 40 years old, 68.27% female, and 31.73% male. The most common symptoms in patients with a positive RT-PCR test were cough (69.23%), fever (42.3%), hyposmia (38.46%), myalgia (38.46%), and ageusia (30.77%). In the positive group, 34.61% presented with ophthalmological symptoms: burning (19.23%), eye pain (11.54%), foreign body sensation (7.7%), hyperemia (7.7%), and tearing (3.84%). Conclusions: Systemic clinical features were characteristic of upper respiratory infection, but neurological findings of hyposmia and anosmia proved to be important markers for suspicion of SARS-CoV-2 infection. Ophthalmic symptoms in patients with COVID-19 were similar to those observed in other viral conditions and may precede systemic conditions. A high rate of self-medication was observed for general symptoms compared with ophthalmological conditions.

RESUMO Objetivo: Avaliar a frequência dos sintomas oftalmológicos, neurológicos e sistêmicos mais comuns em pacientes sintomáticos atendidos no serviço de triagem de COVID-19 do Hospital das Clínicas da UFPE. Métodos: Cento e quatro pacientes com suspeita clínica de infecção por Sars-Cov-2 foram submetidos a avaliação médica e aplicação de questionário sobre a sintomatologia oftalmológica, neurológica e sistêmica. Todos os participantes do estudo tiveram exame de RT-PCR para COVID-19 solicitado. Resultados: A média de idade foi de 38,8 anos, com 44,23% entre 31 e 40 anos. Mulheres corresponderam a 68,27% dos atendimentos e homens a 31,73%. Os sintomas mais frequentes nos pacientes com RT-PCR positivo foram: tosse (69,23%), febre (42,3%), mialgia (38,46%), hiposmia (38,46%), e ageusia (30,77%). Neste grupo, os sintomas oftalmológicos estiveram presentes em 34,61%, sendo: ardor (19,23%), dor ocular (11,54%), sensação de corpo estranho (7,7%), hiperemia (7,7%) e lacrimejamento (3,84%) os mais encontrados. Conclusões: O quadro clínico sistêmico foi característico de infecção respiratória alta, porém os achados neurológicos de hiposmia e anosmia mostraram-se importantes marcadores para a suspeição dos casos de infecção por COVID-19. Os sintomas oftalmológicos dos pacientes com COVID-19 foram semelhantes aos presentes em outros quadros virais, podendo preceder o quadro sistêmico. Houve uma alta taxa de automedicação para os sintomas gerais quando comparado ao quadro oftalmológico.

Cambio de actitud de estudiantes de Enfermería hacia la enfermedad mental mediante aprendizaje experiencial / Change of attitude by Nursing students towards mental illnesses through experiential learning

Introducción: La reforma psiquiátrica y promulgación del Plan Nacional de Salud Mental y Psiquiatría, plantea el desafío de un cambio de actitud hacia las personas con enfermedad mental. Es debido a la estigmatización y discriminación que los pacientes sufren violaciones de derechos humanos, negándoseles la posibilidad de gozar del grado más alto de salud. Para Enfermería de la Universidad Del Desarrollo es un desafío y deber formar profesionales respetuosos de la diversidad y capaces de generar cuidados de enfermería especializados, por lo que se diseñó un curso que incorporó Aprendizaje Experiencial. Objetivo: Promover un cambio de actitud hacia la enfermedad mental en estudiantes de Enfermería de tercer año mediante la incorporación del Aprendizaje Experiencial. Métodos: Estudio de cohorte. Se analizó la existencia de diferencias estadísticamente significativas (test t, 95 por ciento confianza y 0,05 significancia) en los puntajes obtenidos por 52 estudiantes de Enfermería, luego de aplicar la Escala de medición de actitudes hacia los enfermos mentales en futuros técnicos de salud, pre y post realización del curso, previa firma de consentimiento informado. Resultados: El puntaje promedio aumentó de 59,3 (de: 10,5) a 64,5 puntos (de: 8,8). La diferencia promedio en el puntaje total del test antes y después del curso es de 5,2 puntos. Al distinguir entre ítems favorables y desfavorables los puntajes promedios aumentan post realización del curso. Conclusión: Es posible promover un cambio de actitud hacia la enfermedad mental en estudiantes de Enfermería mediante el Aprendizaje Experiencial(AU)

Introduction: The psychiatric reform and the promulgation of the National Plan of Mental Health and Psychiatry posed the challenge of a change of attitude towards people with mental illnesses. Due to stigmatization and discrimination, patients suffer human rights violations, being denied the possibility of enjoying the highest degree of health. For Nursing at Universidad del Desarrollo it is a challenge and a duty to train professionals who are respectful of diversity and capable of generating specialized nursing care, so a course was designed that incorporated experiential learning. Objective: To promote a change of attitude towards mental illnesses in third-year Nursing students through the incorporation of experiential learning. Methods: Cohort study. We analyzed the existence of statistically significant differences (t-test, 95 percent confidence interval and 0.05 significance) in the scores obtained by 52 Nursing students, after applying the Attitudes towards the Mentally Ill Measuring Scale in future health technicians, before and after the completion of the course, after signing informed consent. Results: The average score increased from 59.3 (from: 10.5) to 64.5 points (from: 8.8). The average difference in the total score of the test before and after the course is 5.2 points. Upon distinguishing between favorable and unfavorable items, the average scores increase after the completion of the course. Conclusion: It is possible to promote a change of attitude towards mental illnesses in Nursing students by means of experiential learning(AU)

Ocular toxoplasmosis: evaluation of lacrimal-specific secretory IgA levels in both patients with active and inactive phases of the disease.

Ocular toxoplasmosis can result in recurrent uveitis. Studies have shown that a correlation between active ocular toxoplasmosis and the presence of anti-Toxoplasma gondii secretory IgA (SIgA) in tears. This study compares anti-T. gondii SIgA levels in patients' tears during the acute and inactive phases of toxoplasmic uveitis. Twenty-nine positive tear specific SIgA for T. gondii patients with acute toxoplasmic uveitis were selected and were followed-up for at least two years, when the anti-T. gondii SIgA tears levels were determined. Specific SIgA for T. gondii was negative in 22 patients (75.86%) and positive in seven patients (24.13%) of whom six (85.7%) were followed over three years. Average SIgA levels during the acute phase are 1.54 and decrease significantly to 0.72 (p = 0.0001) during the inactive phase of disease. Because anti-T. gondii SIgA in the tear is negative in 75.86% of patients after the acute phase of infection, T. gondii SIgA levels may be used as a complementary diagnostic marker for active ocular toxoplasmosis.

Anti-Toxoplasma gondii secretory IgA in tears of patients with ocular toxoplasmosis: immunodiagnostic validation by ELISA.

Toxoplasma gondii causes posterior uveitis and the specific diagnosis is based on clinical criteria. The presence of anti-T. gondii secretory IgA (sIgA) antibodies in patients' tears has been reported and an association was found between ocular toxoplasmosis and the anti-T. gondii sIgA isotype in Brazilian patients. The purpose of this study was to provide an objective validation of the published ELISA test for determining the presence of anti-T. gondii sIgA in the tears of individuals with ocular toxoplasmosis. Tears from 156 patients with active posterior uveitis were analysed; 82 of them presented characteristics of ocular toxoplasmosis (standard lesion) and 74 patients presented uveitis due to other aetiologies. Cases of active posterior uveitis were considered standard when a new inflammatory focus satellite to old retinochoroidal scars was observed. The determination of anti-T. gondii sIgA was made using an ELISA test with crude tachyzoite antigenic extracts. Tears were collected without previous stimulation. Detection of sIgA showed 65.9% sensitivity (95% CI = 54.5-74.4), 71.6% specificity (95% CI = 59.8-81.2), a positive predictive value of 72% (95% CI = 60.3-81.5) and a negative predictive value of 65.4% (95% CI = 54.0-75.4). sIgA reactivity was higher in the tears of patients with active posterior uveitis due to T. gondii (p < 0.05). The test is useful for differentiating active posterior uveitis due to toxoplasmosis from uveitis caused by other diseases.

PURPOSE: To describe clinical characteristics of posterior active uveitis presumptively by Toxoplasma gondii (PAUPT) in patients with typical lesion. Tranversal study. METHODS: Sixty-four patients with retinochoroiditis scatter and active satellite lesions examined in Pernambuco, Brazil. All were older than 10 years and immunocompetent. Gender, age, skin color, and residence were recorded. Previous uveitis, visual accuracy, intraocular pressure (IOP), and ocular examination were analyzed. RESULTS: 52% were males, most of them with white skin (68.8%). Mean age 29 years (+/-10.87). Eighty-four percent of the patients lived in the metropolitan area. 56.2% were having the first episode of uveitis. In the damaged eye, visual accuracy mean was 20/200, IOP mean 14.5 mmHg (+/-64). Hyperemia of the conjunctiva was observed in 29.7% of the patients and alterations of the cornea in 51.6%. There were cells in the aqueous humor in 62.7%. 6.2% had posterior synechiae. All had vitreous damage and 45.3% retinal vasculitis. In 42.2% of the patients, lesions were located in zone I of Holland and 90.6% had the size of one discus diameter or greater. Neuritis was observed in 28.2%. Uveitis was more frequent in the right eye (54.7%). CONCLUSION: PAUPT affects young people and the main symptom was reduction of visual acuity. IOP mean was normal. Alterations of the vitreous were observed in all cases. Injuries were equal to one discus diameter or greater and located in zone I of Holland.

Lacrimal secretory IgA in active posterior uveitis induced by Toxoplasma gondii

It is quite difficult to diagnose active toxoplasmosis in patients with ocular toxoplasmosis. Active posterior uveitis presumably due to Toxoplasma gondii infection (APUPT) is seldom produced during a prime-infection; hence most patients do not show high IgM antibodies. High levels of IgA have been described in active toxoplasmosis. The purpose of this study was to investigate possible association between APUPT and the specific anti-parasite sIgA in tears. The study was carried out as case-control. Tears of 25 clinically confirmed APUPT patients and 50 healthy control subjects were analyzed. All were IgG seropositive. Specific sIgA was determined by ELISA assay using T. gondii RH strain crude extract. Anti-T. gondii sIgA was found in 84 percent of the cases and in 22 percent of the control subjects. The intensity of the reaction was higher in APUPT cases (P = 0.007). There was strong association between APUPT patients and lacrimal sIgA (odds-ratio 18.61, P = 0.0001). ELISA test sensitivity was 84 percent and specificity 78 percent . Our data suggest that anti-T.gondii secretory IgA found in tears may become an important marker for active ocular toxoplasmosis.
