Situação epidemiológica das meningites por haemophilus influenzae b na Direção Regional de Piracicaba - São Paulo

O presente estudo objetivou caracterizar a população acometida por meningites por Hib em relação às variáveis demográficas e relativas ao processo saúde-doença, no período de 1992 a 2001, na DIR de Piracicaba, SP, Brasil. Os dados foram coletados a partir de fichas de notificação compulsória, sendo sistematizados através do Programa SINAN. Observou-se que ocorreu um pico de incidência da doença em 1994, e um pico de óbitos em 1999, anteriores à introdução da vacina. Os mais acometidos foram crianças menores de 5 anos, do sexo masculino, confirmando dados de literatura. A maioria dos pacientes foi atendida em unidades hospitalares públicas de Piracicaba e Limeira, referências para as comunidades desses municípios, concretizando um dos princípios do Sistema Único de Saúde (SUS): a regionalização. A introdução da vacina promoveu redução dos casos em cerca de 73%, o que corrobora a sua importância e impele à necessidade de estimular a adesão à vacinação.El presente estudio objetivó caracterizar la población afectada por meningitis causada por Hib en relación a las variables demográficas y relativas al proceso salud-enfermedad, en el período de 1992 a 2001 en la DIR de Piracicaba, SP, Brasil.

Data were collected from disease notification reports, and arranged using the SINAN Data Program . It was observed there was a peak in the incidence of meningitis in 1994 and a peak of deaths in 1999, before the vaccine had been introduced. The most affected group were male children under the age of 5 years, which is in agreement with literature. Most patients received care at public hospitals in the municipalities of Piracicaba and Limeira, which are references for the community of the entire region, which puts into effect one of the axes of the Health System of Brazil (SUS): regionalization. The introduction of the vaccine reduced incidence in about 73%, which corroborates its importance and shows that is necessary to encourage adherence to vaccination

Advanced Atrioventricular Block in Athletes: Prevalence and Role of Anti-Ro/Sjögren Syndrome-Related Antigen A Antibodies

BACKGROUND: Advanced atrioventricular block (AVB), that is, higher than second-degree Mobitz-1, is an abnormal finding in athletes. Despite intensive investigation, in several cases the pathogenesis remains unknown, but frequently pacemaker implantation is still indicated. Increasing evidence points to circulating anti-Ro/Sjögren syndrome-related antigen A (SSA) antibodies cross-reacting with L-type calcium channel and inhibiting the related current as an epidemiologically relevant and potentially reversible cause of isolated AVB in adults. The aim of the study was to determine the prevalence of anti-Ro/SSA-associated advanced AVBs in a large sample of young athletes. METHODS AND RESULTS: A total of 2536 consecutive athletes aged <40 years without a history of cardiac diseases/interventions were enrolled in a cross-sectional study. Resting and exercise electrocardiography was performed, and those presenting any AVB were further evaluated by 24-hour Holter ECG. Athletes with second-degree AVBs and their mothers underwent anti-Ro/SSA testing. Moreover, purified immunoglobulin G from subjects with anti-Ro/SSA-positive and anti-Ro/SSA-negative advanced AVB were tested on L-type calcium current and L-type-calcium channel expression using tSA201 cells. The global prevalence of advanced AVB in the overall sample was ≈0.1%, but the risk considerably increased (2%) when intensely trained postpubertal male subjects were selectively considered. While none of the athletes with advanced AVB showed heart abnormalities, in 100% of cases anti-Ro/SSA antibodies were detected. Ex vivo experiments showed that immunoglobulin G from anti-Ro/SSA-positive but not -negative subjects with advanced AVB acutely inhibit L-type calcium current and chronically downregulate L-type-calcium channel expression. CONCLUSIONS: Our study provides evidence that advanced AVB occurs in young athletes, in most cases associated with anti-Ro/SSA antibodies blocking L-type calcium channels. These findings may open new avenues for immunomodulating therapies to reduce the risk of life-threatening events in athletes, avoiding or delaying pacemaker implantation

Nationwide survey on the management of pediatric pharyngitis in Italian emergency units

Background: Acute pharyngitis is a frequent reason for primary care or emergency unit visits in children. Most available data on pharyngitis management come from primary care studies that demonstrate an underuse of microbiological tests, a tendency to over-prescribe antibiotics and a risk of antimicrobial resistance increase. However, a comprehensive understanding of acute pharyngitis management in emergency units is lacking. This study aimed to investigate the frequency of rapid antigen test use to diagnose acute pharyngitis, as well as other diagnostic approaches, the therapeutic attitude, and follow-up of children with this condition in the emergency units. Methods: A multicentric national study was conducted in Italian emergency departments between April and June 2022. Results: A total of 107 out of 131 invited units (response rate 82%), participated in the survey. The results showed that half of the units use a scoring system to diagnose pharyngitis, with the McIsaac score being the most commonly used. Most emergency units (56%) were not provided with a rapid antigen diagnostic test by their hospital, but the test was more frequently available in units visiting more than 10,000 children yearly (57% vs 33%, respectively, p = 0.02). Almost half (47%) of the units prescribe antibiotics in children with pharyngitis despite the lack of microbiologically confirmed cases of Group A β-hemolytic streptococcus. Finally, about 25% of units prescribe amoxicillin-clavulanic acid to treat Group A β-hemolytic streptococcus pharyngitis. Conclusions: The study sheds light on the approach to pharyngitis in emergency units, providing valuable information to improve the appropriate management of acute pharyngitis in this setting. The routinary provision of rapid antigen tests in the hospitals could enhance the diagnostic and therapeutic approach to pharyngitis

Preventing violence by intimate partners in adolescence: an integrative review

Abstract OBJECTIVE To analyze the scientific literature on preventing intimate partner violence among adolescents in the field of health based on gender and generational categories. METHOD This was an integrative review. We searched for articles using LILACS, PubMed/MEDLINE, and SciELO databases. RESULTS Thirty articles were selected. The results indicate that most studies assessed interventions conducted by programs for intimate partner violence prevention. These studies adopted quantitative methods, and most were in the area of nursing, psychology, and medicine. Furthermore, most research contexts involved schools, followed by households, a hospital, a health center, and an indigenous tribe. CONCLUSION The analyses were not conducted from a gender- and generation-based perspective. Instead, the scientific literature was based on positivist research models, intimately connected to the classic public healthcare model and centered on a singular dimension
