Objective This study aimed to describe the experience with a protocol of therapeutic hypothermia (TH) in southern Brazil. Study Design Newborns with gestational age > 35 weeks with evidence of perinatal asphyxia plus moderate or severe encephalopathy were recruited between March 2011 and November 2017. Whole-body hypothermia for 72 hours, starting within the first 6 hours of life was used. Survivors underwent magnetic resonance imaging (MRI) and electroencephalogram (EEG). The primary outcome was death during hospitalization and neurodevelopment assessed using the Bayley Scales of Infant Development III (BSID III) at 12 months of age. Results A total of 72 newborns were treated (41 with moderate encephalopathy and 31 with severe encephalopathy), of whom 16 died. MRI was performed in 56 patients, and 24 presented some alterations. Fifty-three patients had an EEG: 11 normal, 20 mildly altered, 12 moderately altered, and 10 severely altered. Forty patients were evaluated through BSID III: 45% presented with some delay in neurodevelopment, 8 (20%) had motor retardation, 15 (37.5%) had language delay, and 13 (32.5%) had a delay in cognitive development. Conclusion Mortality and adverse events were similar to those described in large randomized controlled trials. TH is a safe and an effective method of neurologic protection in asphyxiated newborns in a developing country when performed adequately.

Introdução: Diversas diretrizes enfatizam as vantagens do manejo multidisciplinar no cuidado ao paciente com psoríase (PSO) e artrite psoriásica (PSA). O diagnóstico precoce de PSA se relaciona com melhores desfechos em 5 anos. No entanto, o diagnóstico precoce de PSA ainda é um desafio.Métodos: Estudo transversal retrospectivo de pacientes com diagnóstico prévio ou suspeito de PSO e/ou PSA atendidos em ambulatório conjunto de dermatologia e reumatologia do sul do Brasil de janeiro de 2013 a janeiro de 2017.Resultados: Entre os 55 pacientes previamente diagnosticados com PSO, 30,9% (n = 17) foram diagnosticados com PSA. Alterações do tratamento foram feitas em 58,5% (n = 48) dos pacientes, principalmente devido ao mau controle da pele e das articulações. Os imunobiológicos foram a classe de medicamentos mais comumente iniciada, correspondendo a 35,4% (n = 17) das modificações terapêuticas. O metotrexato foi o segundo medicamento mais comumente iniciado (18,8%, n = 9) ou com modificação da dose ou via de administração (20,8%, n = 10), totalizando 39,6% (n = 19) de modificações terapêuticas. Houve um aumento na proporção de pacientes em uso de tratamento sistêmico (79,3%, n = 65).Conclusão: Este estudo reforça a importância da abordagem multidisciplinar no diagnóstico precoce da PSA e demonstra que a abordagem conjunta entre dermatologia e reumatologia é possível de ser realizada no Brasil, com resultados semelhantes aos reportados na literatura internacional.

Describimos el caso de una mujer de 25 años que presentó monoartritis de la articulación interfalángica proximal del cuarto quirodáctil izquierdo 4 días después de recibir la segunda dosis de la vacuna Oxford-AstraZeneca R SARS-CoV-2. No presentaba anomalías en sus radiografías ni en los exámenes de sangre, pero tenía una prima diagnosticada con artritis reumatoide juvenil. La paciente tuvo una excelente respuesta a la medicación antiinflamatoria, la artritis fue transitoria y no dejó secuelas. Los estudios han demostrado que algunas vacunas pueden estar asociadas con la artritis aguda, en particular la vacuna contra el sarampión, las paperas y la rubéola. Las mujeres jóvenes como nuestra paciente parecen ser más susceptibles a la artritis posvacunación. La mayoría de los casos notificados fueron transitorios y no dejaron secuelas articulares, por lo que no contraindicamos nuevas dosis de la vacuna Oxford-AstraZeneca R SARS-CoV-2 (en caso de recomendarse en el futuro) en este caso.

Homocystinuria is one of a group of genetic disorders called inborn errors of metabolism. It is characterized by a deficiency of the enzyme that converts homocysteine to cystathionine. Keratoconus is an ophthalmologic condition characterized by thinning of the corneal stroma, which causes the cornea to assume a conical shape. There is little information in the scientific literature about the association between keratoconus and homocystinuria. We believe that a collagen cross-linking defect may be the key to understand the connection between these two conditions. This case report describes a 38-year-old male patient with a diagnosis of classical homocystinuria since age 13. At the age of 16, he received a diagnosis of asymmetrical keratoconus when referred for lensectomy with vitrectomy of his left eye. To the best of our knowledge, this is the first report of a patient with simultaneous homocystinuria and keratoconus.
