Eccema coxsackium y otra presentación atípica de la enfermedad de mano-pie-boca

La enfermedad de mano-pie-boca (EMPB) es una de las enfermedades exantemáticas más frecuentes en niños menores de cinco años, generalmente producida por los virus Coxsackie A16 y enterovirus 71. En los últimos años se están observando manifestaciones dérmicas diferentes a la habitual causadas por serotipos menos frecuentes como el Coxsackievirus A6. Los pacientes con la EMPB por Coxsakievirus A6 presentan fiebre y síntomas sistémicos como la EMPB típica, pero tienen una manifestación cutánea más grave, pudiendo simular un cuadro Gianotti Crosti-like, o, incluso, un eccema herpeticum. En estos casos, recomendamos analizar el serotipo de enterovirus para prevenir pruebas diagnósticas innecesarias o tratamientos antivirales inapropiados. Presentamos dos casos en niños menores de cinco años, de presentación atípica de EMPB, atendidos en nuestro Servicio de Urgencias. Ambos referían como antecedente padecer dermatitis atópica.

Acute hemorrhagic necrotizing pancreatitis in falciparum malaria

Malaria is a pathology caused by a parasite called Plasmodium, characteristic of tropical countries. The most frequent symptomatology includes cerebral malaria, jaundice, convulsive crisis, anemia, hypoglycemia, kidney failure and metabolic acidosis, among others. We are presenting the case of a patient diagnosed with malaria who suffered from acute hemorrhagic necrotizing pancreatitis and evolved poorly, as an example of this combination of symptoms, rarely found in our country.

Circuit resistance training improved endothelial dysfunction in obese aged women

Introduction: It is widely accepted that obesity is associated with endothelial dysfunction. In a recent paper, we have also found circuit resistance training may reduce visceral fat in obese aged women. Accordingly, the current study was conducted to ascertain the effects of circuit resistance training on markers of endothelial dysfunction in this population group. Methods: In the present interventional study, a total of 48 obese aged women were recruited from the community. Twenty-four of them were randomly assigned to perform a 12-week resistance circuit training programme, 3-days per week. This training was circularly performed in 6 stations: arm curl, leg extension, seated row, leg curl, triceps extension and leg press. The Jamar handgrip electronic dynamometer was used to assess maximal handgrip strength of the dominant hand. Lastly, serum samples were analysed using an immunoassay (ELISA) for endothelin-1, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1). Results: When compared to baseline, resistance training significantly reduced serum levels of endothelin-1 (2.28 ± 0.7 vs. 1.98 ± 1.1 pg/ml; p = 0.019; d = 0.67) and ICAM-1 (290 ± 69 vs. 255 ± 76 ng/ml; p = 0.004; d = 0.92) in the experimental group. No significant changes in any of the tested outcomes were found in the control group. Conclusion: A short-term circuit resistance program improved endothelial dysfunction in aged obese women. Further studies on this topic are still required to consolidate this approach in clinical application.
