Guillain-Barré Syndrome (GBS) is a rare disorder of the nervous system, where the patient's immune system attacks the peripheral nerve cells in the arms and legs, causing muscle weakness, loss of sensation and sometimes total paralysis. The origin of this disorder has been associated with immune responses triggered by post-infection with Campylobacter spp. However, when there is no obvious cause of the disease, it is usually not investigated due to the greater interest in the treatment. Therefore, most cases are reported as idiopathic origin. Between January and March 2016 worldwide, GBS outbreaks were reported in 8 countries, linked to the emergence of the Zika virus. In Peru, since the end of 2018, outbreaks of GBS have been reported more frequently and although no association with Zika has been confirmed, the increase in cases, the geographical extension where they occurred and the c...

Background: The respiratory syncytial virus (RSV) responsible for pneumonia and cause of hospitalization in critical pediatric areas, can cause deaths in infants. Report of case: Five infrequent cases were analyzed at a seasonal level in a hospital in northern Peru during the period from April to June 2019, where patients with pneumonia caused by RSV were observed, confirmed by direct immunofluorescence, chest radiography and with the presence of associated clinical findings hepatomegaly and atelectasis. Of the 05 cases: 4 correspond to boys and a girl, aged 2-7 months, all were hospitalized, presented wheezing, crackles and polytirage as prevalent signs at admission, all developed severe pneumonia and complications, were recorded two deaths in children under 6 months of age, with complications of sepsis, PARDS, and mechanical ventilation. Conclusion: the cases reflect characteristic cli...

Objective: To describe the seroprevalence of and risk factors for brucellosis and leptospirosis in urban citizens with backyard breeding in the district of José Leonardo Ortiz, Chiclayo. Methods: Cross-sectional study including 90 citizens during the month of October and December of 2016. IgM and IgG specific antibodies for brucellosis and leptospirosis were determined using the indirect ELISA method. Factors associated with these diseases were gathered using a structural survey. Results: The seroprevalence of brucellosis and leptospirosis was 2.2% and 28.9%, respectively. The most common environmental features of the population were that 73.3% use latrines 83.3% had contact with stagnant water and 62.2% had contact with rodents. No association between the variables looked for and these two diseases were found. Conclusions: We found a high seroprevalence of leptospirosis but a low ...
