Prevalence and risk factors for dry eye disease: the Sao Paulo dry eye study / Prevalência e fatores de risco para doença do olho seco: o estudo de olho seco - São Paulo

ABSTRACT Purpose: To estimate the prevalence and risk factors of dry eye disease symptoms and clinical diagnoses in Sao Paulo city, state of Sao Paulo, Brazil. Methods: A total of 582 participants over 18 years old, living in the east zone of Sao Paulo city responded to a short questionnaire. Dry eye disease was on that is defined by the presence of severe symptoms or previous clinical diagnosis of dry eye disease by an ophthalmologist. The association between dry eye disease and possible risk factors was assessed. Results: Overall dry eye disease severe symptoms and/or clinical diagnoses prevalence was calculated as 24.4% for both sexes. Women presented a higher frequency of severe symptoms of dry eye disease (16.07%) than men (8.48%; p=0.0244), as well as the composite of severe symptoms or diagnosed dry eye disease, presented by 26.86% of women and 18.18% of men (p=0.0366). In women, ages between 55 to 75 years old were associated with dry eye disease severe symptoms (OR=3.11; 95%CI 1.56-6.23, p=0.001) and diagnosed dry eye disease (OR=2.02; 95% CI 1.04-3.93, p=0.037). Hypertension was significantly associated with dry eye disease symptoms (OR=1.98; 95% CI 1.14-3.43, p=0.015) and diagnoses (OR=3.54; 95% CI 1.92-6.53, p=0.0001) in women. Eye drops use was associated with severe symptoms of dry eye disease and diagnosed dry eye disease in both women and men (p≤0.01). Conclusions: Dry eye disease prevalence in Sao Paulo city is higher in women than in men. Age and hypertension were stronger risk factors of dry eye disease for women, while eye drops use was a significant indicator of dry eye disease for both sexes.

RESUMO Objetivo Estimar a prevalência e os fatores de risco para os sintomas e o diagnóstico clínico da doença do olho seco na cidade de São Paulo, estado de São Paulo, Brasil. Métodos: Quinhentos e oitenta e dois participantes acima de 18 anos, residentes na zona leste da cidade de São Paulo responderam a um questionário de três perguntas sobre olho seco. A doença do olho seco foi definida pela presença de sintomas severos ou diagnóstico clínico prévio de doença do olho seco por um oftalmologista. A associação entre doença do olho seco e possíveis fatores de risco foi avaliada. Resultados: A prevalência de sintomas graves da doença do olho seco e/ou diagnóstico clínico foi calculada em 24,4% para ambos os sexos. O sexo feminino apresentou uma frequência maior de sintomas severos da doença do olho seco (16,07%) que o sexo masculino (8,48%; p=0,0244), assim como a associação de sintomas severos ou diagnóstico de doença do olho seco, foi de 26,86% no sexo feminino e 18,18% no sexo masculino (p=0,0366). No sexo feminino, a faixa etária entre 55 e 75 anos de idade foi associada com sintomas severos da DOS (odds ratios (OR) = 3,11; IC 95% 1,56-6,23; p=0,001) e com doença do olho seco diagnosticada (OR=2,02; IC 95% 1,04-3,93; p=0,037). Hipertensão foi associado com sintomas da doença do olho seco (OR=1,98; IC 95% 1,14-3,43; p=0,015) e diagnóstico da doença do olho seco (OR=3,54; IC 95% 1,92-6,53; p=0,001) no sexo feminino. Uso de colírios foi associado a sintomas severos e diagnóstico da doença do olho seco em ambos os sexos (p≤0,01). Conclusão: A prevalência da doença do olho seco na cidade de São Paulo é mais frequente no sexo feminino que no masculino. Idade e hipertensão foram fatores de risco maiores para doença do olho seco no sexo feminino, enquanto uso de colírios foi um indicador de doença do olho seco para ambos os sexos.

Autistic spectrum disorders in brazilian primary care: telehealth and face-to-face training method / Treinamento sobre transtorno do espectro autista na atenção básica do Brasil: teleducação e presencial / Entrenamiento en transtorno del espectro autista en la atención básica brasileña: teleducación y presencial

Primary care professionals are usually the first ones to detect symptomns of autism. We have developed and evaluated an educational model via a combined telehealth and face-to-face approach to handle autism spectrum disorders (ASD) and child mental health. The training comprised two modules involving distance-learning and face-to-face teaching environments. A total of 150 healthcare professionals - 75 doctors and 75 nurses - from five Brazilian cities were trained. Videos about ASD and child mental health were developed for the distance-learning module. The face-toface module was based on training regarding "Mental health communication skills for child and adolescent primary care." The professionals were evaluated before and after training utilizing a specific knowledge questionnaire and surveys on Knowledge, Attitude, and Practice (KAP). Knowledge acquisition, practice, and attitude improved significantly after training (p < 0.01). Our results indicated that the use of interactive tele-education to train professionals in primary care is feasible and effective.

Os primeiros sintomas de transtorno do espectro autista (TEA) são detectados por profissionais da atenção básica. O objetivo deste estudo foi desenvolver e avaliar um modelo de treinamento via telemedicina e workshop presencial sobre TEA e saúde mental infantil para médicos e enfermeiros da atenção básica. Participaram do treinamento 150 profissionais de cinco cidades brasileiras. No módulo a distância, foram desenvolvidos vídeos sobre TEA e os principais transtornos da infância, e no presencial foi baseado no treinamento "Técnicas de comunicação para lidar com saúde mental de crianças e adolescentes na atenção primaria".

Predictors of Nerve Stimulator Success in Patients With Overactive Bladder / 대한배뇨장애요실금학회지

PURPOSE: To identify factors associated with successful sacral nerve stimulator (SNS) trial after SNS implantation for the treatment of medication refractory overactive bladder (OAB). METHODS: Patients undergoing treatment for OAB at Lahey Hospital and Medical Center between 2004 and 2016 were identified. Patients undergoing SNS placement were identified; SNS success was defined as permanent implantation of the SNS. Demographic, clinical and treatment data were extracted from patient charts; uni- and multivariate analyses were conducted to identify factors associated with SNS treatment success. RESULTS: A total of 128 patients were included. On univariate analysis, male sex, prior diagnosis of benign prostatic hyperplasia, and lower volume at first urge on urodynamics (UDS) were associated with unsuccessful SNS trial. On multivariate analysis, male sex (odds ratio [OR], 0.145; 95% confidence interval [CI], 0.036–0.530) and lower volume at first urge on UDS (OR, 0.982; 95% CI, 0.967–0.995) were associated with unsuccessful SNS trial. A threshold value of 100 mL at first urge during preoperative UDS had a specificity of 0.86 in predicting SNS success in men. CONCLUSIONS: SNS is frequently successful at relieving OAB symptoms. Male patients and those with lower volumes at first urge on UDS, particularly below 100 mL, are more likely to have an unsuccessful SNS trial. Patients in these groups should be counseled on the lower likelihood of SNS success.

Paratuberculose em caprinos e ovinos no Estado da Paraíba / Paratuberculosis in goats and sheep in the state of Paraiba

Mediante o teste de ELISA foi determinada a presença de anticorpos para Mycobacterium avium subsp. paratuberculosis (map) em amostras de soro de 734 caprinos e 392 ovinos, sem sinais clìnicos aparentes, provenientes de 14 Municipios do semiárido Paraibano. Em caprinos, a frequência média de anticorpos de 44,86± 22,91% e em ovinos foi de 52,96±31,49. Das 46 propriedades estudadas, 44 (95,65%) apresentaram pelo menos um animal soropositivo. Nos 14 municípios avaliados houve presença de animais sorologicamente positivos, variando de 20% a 70%. Em caprinos sem raça definida e mestiços a frequência (48,56%) foi significativamente inferior (P<0,0270) que a de caprinos de raças puras (57,24%). Em ovinos com escore de 1 a 3 a frequência (59,39%) foi significativamente maior (P=0,0034) que a frequência em ovinos com escore superior a 3 (42,42%). Não houve diferença significativa nas frequências em caprinos e ovinos de diferentes idades, em caprinos com diferente escore corporal e em ovinos de diferentes raças. No exame microbiológico, em cultivos em meio HEYM com micobactina J, foram observadas colônias semelhantes às do Map em 9 (6,58%) das 180 amostras de fezes, sendo uma de caprinos e 8 de ovinos. Na coloração de Ziehl Nieelsen as bactérias apresentavam características morfo-tintorias de Map. Os resultados obtidos indicam alta frequência de caprinos e ovinos infectados com Map no semiárido da Paraíba, tornando-se necessário desenvolver pesquisas sobre a epidemiologia e forma de controle da doença nas condições de criação da região.

Antibodies to paratuberculosis were determined by ELISA in serum samples of 734 goats and 392 sheep, without clinical signs, from 14 municipalities of the semiarid region of Paraíba state, Brazil. In goats, average frequency of antibodies was 44.86±22.91% and in sheep was 52.96±31.49%. All municipalities had affected animals with a frequency varying from 20% to 70%. In goats of unknown breed and crossbreds the prevalence (48.56%) was significantly lower (P=0.0270) than in pure breed goats (57.24%). In sheep with body scores of 1 to 3, the frequency (59.39%) was significantly higher (P=0.0034) than in sheep with body score from 3 to 5 (42.42%). No significant differences were observed in goats and sheep of different ages, in goats with different body score, and in sheep of different breeds. In the microbiologic examination, after 16 weeks of incubation in HEYM medium with mycobactin J, colonies similar to those of do Mycobacterium avium subsp. paratuber culosis were observed in cultures of 9 (6.58%) out of 180 fecal samples, being one from goats and 8 from sheep. In the Ziehl Nieelsen the bacteria had morphologic and staining characteristics similar to M. avium subsp. paratuberculosis. These results suggest that paratuberculosis is endemic with high prevalence in the semiarid region of Paraíba. It is necessary to develop research on the epidemiology and control measures of the disease in the conditions of this region. Also the risk for human beings should be determined, mainly in relation with milking goats.

Diagnostic dilemma in coinfection.

A Fifteen years girl belonging to a low socioeconomic status was admitted with peritonsillar abscess caused by methicillin resistant Staphylococcus aureus (MRSA), high fever, diarrhoea and septicaemic shock. Initial blood cultures and widal test, stool cultures and routine stool examination were non-contributory to the diagnosis. A bone marrow culture in the second week confirmed the diagnosis of Salmonella typhi infection. Examination of a fresh stool sample showed cysts of Entamoeba histolytica. She was treated with ciprofloxacin, metronidazole, augmentin and ceftriaxone. She had no clinical evidence of immunosuppression prior to this episode and her HIV test was negative. This case report highlights the presence of community acquired MRSA infection causing perititonsillar abscess, and the diagnostic dilemma of fever and diarrhoea due to coinfection with Salmonella typhi and Entamobea histolytica.

Validity of women's self-reported obstetric complications in rural Ghana.

This retrospective study assessed the utility of women's self-reports to identify obstetric complications in rural Ghana. All consenting obstetric and postpartum inpatients, presenting from the seventh month of gestation to 42 days postpartum, were interviewed at the Holy Family Hospital, Techiman and were asked about their signs and symptoms. A combination of clinical examination and laboratory testing of urine and blood samples was used for determining case status. Self-reported obstetric complications of 340 women were compared with the corresponding diagnostic status for their sensitivity, specificity, predictive value, and test-efficiency. Using algorithms that could not be practically applied at the community level, self-reported symptoms correctly identified the majority (75%) of complicated and uncomplicated pregnancies, but missed one-quarter of cases requiring emergency obstetric care. The positive predictive value of 50% indicates that women's self-reported symptoms should not be used in estimating the incidence of these conditions or in identifying women requiring referral in this population.

Recurrent haematuria in coexisting IgA nephropathy and interstitial nephritis.

We report here a case of recurrent hematuria in a young man who presented with deteriorating renal function due to interstitial nephritis, secondary to, probably enteric fever. Immunofluorescence studies showed IgA nephropathy and ultrastructural studies revealed thin basement membrane nephropathy.

Expression of a cell death marker (clusterin) in muscle target fibers

Descrevemos, pela primeira vez, a expressäo de imunorreatividade para clusterina em músculo esquelético. Clusterina, proteína relacionada ao processo de morte celular programada (apoptosis), encontrou-se especificamente muito aumentada em fibras musculares com "target" (FT). Todas as FT encontradas em 50 biópsias musculares de pacientes com diferentes doenças neuromusculares apresentaram alta concentraçäo de clusterina no centro das FT. Clusterina näo esteve semelhantemente aumentada em fibras com "targetóide" ou com "core". A alta expressäo de clusterina em "target" indica que FT podem ser o início de apoptosis e que há intima relaçäo entre FT e desnervaçäo aguda
