Epidemiological Analysis of Hospitalizations for Head Trauma in Hospitals of Belém do Pará, Between 2015 and 2019

Objective:The study aimed to describe the epidemiology of cases of hospitalization due to TBI in Belém/PA, between 2015 and 2019.Methodology:This is a descriptive epidemiological study, with a retrospectiveapproach, whose data were obtained through consultation in the Notifiable Diseases Information System.Results:Were 2.103 cases were reported, of which (75, 3%) were male, 80,7% without race/color information, coming largely from the emergency department, with predominance of admission to a Municipal Emergency Hospital (78, 2%). Conclusion:The high incidence of TBI in certain groups, associated with the present need to carry out complete care records, reinforces the need for health information, serving as an epidemiological basis and for the management of services. Therefore, it is extremely important to know the possible causes and act in the planning and elaboration of strategies that aim to prevent the numerous cases of TBI

Immunogenicity and safety of the combined vaccine for measles, mumps, and rubella isolated or combined with the varicella component administered at 3-month intervals: randomised study

BACKGROUND Field testing required to license the combined measles, mumps, and rubella (MMR) vaccine must take into account the current recommendation of the vaccine in Brazil: first dose at 12 months and second dose at 15 months of age in combination with a varicella vaccine. OBJECTIVES This study aimed to evaluate the clinical consistency, immunogenicity, and reactogenicity of three batches of MMR vaccine prepared with active pharmaceutical ingredients (API) from Bio-Manguinhos, Fiocruz (MMR-Bio), and compare it to a vaccine (MMR produced by GlaxoSmithKline) with different API. METHODS This was a phase III, randomised, double-blind, non-inferiority study of the MMR-Bio administered in infants immunised at health care units in Pará, Brazil, from February 2015 to January 2016. Antibody levels were titrated by immunoenzymatic assays. Adverse events were recorded in diaries. FINDINGS Seropositivity levels after MMR-Bio were 97.6% for measles, 84.7% for mumps, and 98.0% for rubella. After the MMRV vaccine, seroconversion rates and GMT increased substantially for mumps. In contrast, approximately 35% of the children had no detectable antibodies to varicella. Systemic adverse events were more frequent than local events. CONCLUSION The demonstration of batch consistency and non-inferiority of the Bio-MMR vaccine completed the technology transfer. This is a significant technological achievement with implications for immunisation programs.

Atrial fibrillation in acute Chagas disease acquired via oral transmission: a case report

Abstract Atrial fibrillation (AF), a type of supraventricular arrhythmia increases the risk of thromboembolism. Chagas disease has been reported in the Brazilian Amazon region over approximately 20 years. Cardiac abnormalities are recorded in at least 50% of patients and among these, 3.3% develop AF. We describe a case of a 41-year-old man from Muaná, Pará State, who reported a 30-day history of a febrile illness. Acute Chagas disease was confirmed, and an electrocardiogram revealed AF. He was treated with antiparasitic and anti-arrhythmic drugs, beta blockers, and anticoagulants. Reversion to sinus rhythm was observed at his 9-month follow-up.

Variabilidade genética de amostras de Salmonella Typhi isoladas de surto e de casos esporádicos ocorridos em Belém, Brasil / Genetic variability of Salmonella Typhi samples isolated from outbreaks and sporadic cases of typhoid fever in Belém, Brazil

INTRODUÇÃO: Salmonella Typhi é o agente da febre tifóide (doença caracterizada por febre, cefaléia, mialgia, artralgia, diarréia ou constipação), cujo quadro pode se complicar e levar o paciente a óbito. No Brasil, a febre tifóide é endêmica nas regiões Norte e Nordeste, com surtos ocorridos nos meses de intenso calor. OBJETIVO: Analisar e comparar a variabilidade genética de S. Typhi isoladas de surto e casos esporádicos de febre tifóide ocorridos em determinado período na cidade de Belém (PA). MATERIAL E MÉTODOS: Foram analisadas 20 amostras de S. Typhi: 10 isoladas de um surto ocorrido no bairro do Guamá, Belém, entre os meses de dezembro/2005 e março/2006, e 10 de casos esporádicos ocorridos em diferentes localidades da mesma cidade e no mesmo período do surto. A caracterização genética foi realizada pela análise do perfil de macrorrestrição obtido pela enzima XbaI e definido por eletroforese em gel de campo pulsado (PFGE). RESULTADOS: A análise de XbaI-PFGE das amostras estudadas demonstrou uma similaridade genética de 83 por cento a 100 por cento. CONCLUSÃO: Este estudo pôde demonstrar a relação clonal das amostras S. Typhi causadoras de surto e de casos esporádicos de febre tifóide ocorridos na cidade de Belém no período de dezembro/2005 a março/2006.

BACKGROUND: Salmonella Typhi is the causative agent of typhoid fever, illness characterized by fever, migraine, myalgia, arthralgia, diarrhea or constipation, which may have complications and cause death. In Brazil, the typhoid fever is endemic in the Northern and Northeastern regions, with outbreaks occurring in scorching months. OBJECTIVE: To analyse and compare the genetic variability of S. Typhi strains isolated from outbreaks and sporadic cases of typhoid fever occurred in the city of Belém (PA) between December 2005 and March 2006. MATERIAL AND METHODS: Twenty samples of S. Typhi were analyzed: 10 of them were isolated from an outbreak occurred in Guamá neighborhood in Belém, between December 2005 and March 2006, and the other 10 were isolated from sporadic cases in different neighborhoods of the same city in the same outbreak period. The genetic characterization was performed by macrorestriction analysis of genomic DNA with XbaI enzyme defined by pulsed-field gel electrophoresis (PFGE). RESULTS: The Xbal-PFGE analysis of the studied samples revealed a genetic similarity of 83 percent to 100 percent. CONCLUSION: This study demonstrated the clonal relation between the S. Typhi samples from the outbreak and from the sporadic cases of typhoid fever occurred in the city of Belém between December 2005 and March 2006.

Complicações na febre tifóide: relato de um caso atípico e considerações sobre suas implicações no diagnóstico e no controle / Complications in typhoid fever: description of an anusual case and its bearing on diagnosis and control

Apresenta-se um caso de febre tifóide que cursou com hepatite colestática cujo diagnóstico foi dado pela coprocultura. A negativação das provas para hepatites virais, malária e leptospirose, e a pronta resposta ao tratamento com ciprofloxacina corroboraram o diagnóstico de febre tifóide. Nas áreas endêmicas, essa hipótese deve ser lembrada diante das icterícias febris.

A case of typhoid fever with colestatic hepatitis is described, with diagnosis made by stool culture. Examination for malaria, leptospirosis and viral hepatitis were all negatives. These results and the rapid response of the patient to treatment with ciprofloxacin confirmed the diagnosis of typhoid fever and indicate the importance of considering typhoid fever in cases of fever with jaundice.
