Abstract Background Psoriasis is a skin disease that affects 1.3% of Brazilians. The use of teledermatology (TD) in the public health sector has democratized access to dermatological care. Objective To analyze TD exams with suspected and/or diagnosed psoriasis performed between 2016‒2020 in the state of Santa Catarina (SC). Methods Analytical cross-sectional observational study that used secondary data collected from the records of TD exams from the Telemedicine and Telehealth System (TTS) of SC. The associations were evaluated by the chi-square test and Student'st test. The significance level was set at 5% (p < 0.05). Results During the period, 6,146 TD exams were related to psoriasis, 58% due to the diagnosis provided by the reporting dermatologist and 42% exclusively due to the suspected disease on the request of the examination. The male sex predominated among the diagnoses of dermatosis (51%; p < 0.001). Regarding risk classification, psoriasis diagnoses were predominantly yellow (58.7%; p < 0.001) or blue (39.7%; p < 0.001) risk, respectively indicating moderate to severe psoriasis (referral to tertiary care) and mild psoriasis (treatment in the primary health care [PHC] level). True positive tests, suspected by PHC and diagnosed with psoriasis through TD, were 34.1% (p < 0.001). Study limitations The TD service is available only for the public health network and analysis for a limited period (five years). Conclusions Psoriasis diagnoses performed by TD, when compared to other dermatoses, tend to receive treatment at the primary (p < 0.001) or tertiary (p < 0.001) health care level, reducing the number of referrals to the secondary care level. 13 1 3 1.3 Brazilians (TD andor 20162020 2016 2020 2016‒202 SC .

Resumo Objetivo: Analisar o impacto da vacina adsorvida difteria, tétano e coqueluche (pertússis acelular), tipo adulto (dTpa), materna, na incidência de coqueluche em crianças menores de 1 ano no Brasil, de 2008 a 2018. Métodos: Estudo de tipo ecológico, descritivo de tendência temporal, utilizando-se de dados dos sistemas de vigilância do Departamento de Informática do Sistema Único de Saúde (Datasus). Foram calculadas taxas de incidência e razão das taxas de incidência (IRR), com respectivos intervalos de confiança de 95% (IC95%). Resultados: O número de casos de coqueluche foi de 20.650. Houve redução na incidência de coqueluche no período pós-vacinal, de 26,6% (IRR = 0,73; IC95% 0,66;0,82) nas crianças de 3 meses a 1 ano incompleto, e de 63,6% (IRR = 0,36; IC95% 0,15;0,58) nas crianças de zero a 2 meses. Conclusão: O aumento da cobertura da vacinação com dTpa materna correspondeu à redução na incidência de coqueluche, principalmente na faixa etária de zero a 2 meses.

Abstract Objetive: To analyze the impact of maternal vaccination coverage with diphtheria-tetanus-acellular pertussis (Tdap) adsorbed vaccine for adults on pertussis incidence in children under 1 year old in Brazil from 2008 to 2018. Methods: This was a descriptive ecological temporal trend study using data from surveillance systems managed by the Brazilian National Health System Information Technology Department (DATASUS). Incidence rates and incidence rate ratios (IRR) were calculated with respective 95% confidence intervals (95%CI). Results: There were 20,650 pertussis cases in the study period. In the post-vaccination period there was a 26.6% reduction (IRR = 0.73; 95%CI 0.66;0.82) in pertussis incidence among children aged from 3 months up to but not including 1 year old, and a 63.6% reduction (IRR = 0.36; 95%CI 0.15;0.58) among children from birth to 2 months old. Conclusion: The increase in maternal Tdap vaccination coverage coincided with a reduction in pertussis incidence, especially in the birth to two-month-old age group.

Resumen Objetivo: Analizar la incidencia de tos ferina en menores de 1 año y su relación con la cobertura de vacunación materna por la vacuna adsorbida contra la difteria, el tétanos y la tos ferina (tos ferina acelular) tipo adulto (dTpa), de 2008 a 2018, en Brasil. Métodos: Estudio ecológico descriptivo de tendencia temporal utilizando datos de los sistemas de vigilancia del Departamento de Informática do Sistema Único de Saúde (Datasus). Se calcularon los tasas de incidencia y las razones de tasas de incidencia (RTI) con los respectivos intervalos de confianza del 95% (IC95%). Resultados: El número de casos de tos ferina en el período de estudio fue de 20,650. Hubo una reducción en la incidencia de tos ferina en el período post-vacunación. En los niños de 3 meses a 1 año incompleto, la reducción fue del 26,6% (RTI = 0,73; IC95% 0,66;0,82), mientras que en el otro grupo la diferencia relativa fue del 63,6% (RTI = 0,36; IC95% 0,15;0,58)]. Conclusión: La vacunación materna con dTpa coincide con una reducción en la incidencia de tos ferina, especialmente en el grupo de edad de cero a 2 meses.

Abstract The use of coronavirus disease 2019 RNA vaccines in pregnant women led to reports on the first cases of newborns with antibodies to sudden acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a phenomenon that was unknown when using immunizations with inactivated viruses. Thus, this study aimed to report a case of passive anti-SARS-CoV-2 immunity in a newborn through immunoprophylaxis of a pregnant woman who received the CoronaVac® vaccine in the third trimester of pregnancy. Twenty-four hours after delivery, samples were collected from the newborn and screened by enzyme immunoassays, which revealed antibodies to SARS-CoV-2.
