RESUMO

Background: Surgical glove perforation constitutes a risk for the maintenance of aseptic technique and the risk of surgical site infection and occupational exposure to blood borne infections for healthcare workers. Aim: To identify the frequency of glove perforation in selected surgical procedures. Methods: A cross-sectional descriptive observational study was carried out in the surgical unit of the Joaquin Albarrán Hospital (La Habana, Cuba) during the period September-December 2019. Gloves used by surgeons in major urgent or elective surgical procedures were collected and tested for perforations. Findings: 757 gloves from 149 surgeons and 8 surgical specialties were tested and 95 (25.8%) had perforations. The highest frequencies of glove perforations were reported in vascular surgery (50.0%), proctology (37.9%), urology (28.0%) and general surgery (26.1%). The selected surgical procedures with the highest frequencies were open radical nephrectomy (87.5%), splenectomy (57.1%), open adenomectomy (55.6%), limb amputation (46.2%) and hysterectomy (41.7%). Glove perforation occurred more frequently in consultant surgeons (28.8%) than in residents (20.9%) (P = 0.021), in surgeons with more years of surgical experience (P = 0.003) and longer procedure duration (P = <0.001). Most glove perforations were identified in the left hand (64.1%), while 23.1% were in the right hand and 12.8% in both hands. 51.2% occurred in thumb and index finger. Differences in the patterns of glove perforation were observed among the different surgical procedures. Conclusions: Our findings provide insights into the risk of glove perforation during selected surgical procedures and the need for prevention strategies to reduce adverse consequences of glove perforation in patients and healthcare workers.

RESUMO

Introducción: La duración de la inmunidad natural generada por la COVID-19 está por definir, lo que determina la probable reinfección. Objetivo: Destacar la necesidad de mantener las medidas de prevención a propósito de un caso de reinfección en un trabajador sanitario. Presentación de caso: Paciente femenina de 48 años de edad con antecedentes de salud que, en junio, 2020 y marzo, 2021 se le diagnóstica la COVID-19, en ambos casos con el comportamiento de enfermedad sintomática leve. Después de 24 horas de comenzar con cefalea, mareos y tos seca se confirma el diagnóstico de infección por SARS CoV-2 con PCR positivo y umbral de ciclo (CT) en 24.84. Pasados 9 meses y 9 días de la infección original, y dos días posteriores a recibir la vacuna BNT162b2 (Pfizer-BioNTech), comienza con malestar general, tos seca, secreción nasal y dolor de garganta, con PCR positivo y CT de 17.61. Conclusiones: La posibilidad de la reinfección por la COVID-19 orienta la necesidad de fortalecer las acciones de prevención de la transmisión en instituciones de salud en tanto las evidencias científicas nos provean de recursos más eficaces para su control(AU)

Introduction: The duration of natural immunity generated by COVID-19 is yet to be defined, which determines the probable reinfection. Objective: To analyze issues related to natural infection and the need to maintain prevention practices regarding a case of reinfection in a health care worker. Case presentation: Forty-eight-year-old female patient without comorbidities who was diagnosed with COVID-19 in June 2020 and March 2021, in both cases as a mild symptomatic disease. Twenty-four hours after the onset with headache, dizziness, and dry cough, the diagnosis of SARS CoV-2 infection was confirmed by positive PCR and cycle threshold (CT) at 24.84. Nine months and nine days after original infection, and two days after receiving the BNT162b2 vaccine (Pfizer-BioNTech), the patient began with general malaise, dry cough, runny nose, and sore throat, with a positive PCR and CT of 17.61. Conclusions: The possibility of reinfection by COVID-19 points to the need to strengthen transmission prevention practices in healthcare facilities as long as scientific evidence provides us with more effective resources for its control(AU)

RESUMO

BACKGROUND: Short-term peripheral venous catheter-related bloodstream infection (PVCR-BSI) rates have not been systematically studied in resource-limited countries, and data on their incidence by number of device days are not available. METHODS: Prospective, surveillance study on PVCR-BSI conducted from September 1, 2013, to May 31, 2019, in 727 intensive care units (ICUs), by members of the International Nosocomial Infection Control Consortium (INICC), from 268 hospitals in 141 cities of 42 countries of Africa, the Americas, Eastern Mediterranean, Europe, South East Asia, and Western Pacific regions. For this research, we applied definition and criteria of the CDC NHSN, methodology of the INICC, and software named INICC Surveillance Online System. RESULTS: We followed 149,609 ICU patients for 731,135 bed days and 743,508 short-term peripheral venous catheter (PVC) days. We identified 1,789 PVCR-BSIs for an overall rate of 2.41 per 1,000 PVC days. Mortality in patients with PVC but without PVCR-BSI was 6.67%, and mortality was 18% in patients with PVC and PVCR-BSI. The length of stay of patients with PVC but without PVCR-BSI was 4.83 days, and the length of stay was 9.85 days in patients with PVC and PVCR-BSI. Among these infections, the microorganism profile showed 58% gram-negative bacteria: Escherichia coli (16%), Klebsiella spp (11%), Pseudomonas aeruginosa (6%), Enterobacter spp (4%), and others (20%) including Serratia marcescens. Staphylococcus aureus were the predominant gram-positive bacteria (12%). CONCLUSIONS: PVCR-BSI rates in INICC ICUs were much higher than rates published from industrialized countries. Infection prevention programs must be implemented to reduce the incidence of PVCR-BSIs in resource-limited countries.

RESUMO

RESUMEN Las infecciones del sitio quirúrgico constituyen un problema de calidad de los cuidados a la salud, las cuales son potencialmente prevenibles mediante la aplicación de guías de prevención basadas en evidencias. Se pretendedescribir la evolución histórica de las prácticas de uso profiláctico de antibióticos en cirugía de colon desde el siglo pasado. Se analizó literatura publicada en las últimas cinco décadas en MEDLINE, Infomed y otras fuentes secundarias. Se destaca la evolución del uso combinado de antimicrobianos (aminoglucósidos, penicilina, cefalosporinas y nitroimidazoles) asociados a la preparación enérgica del colon en la década de los 70 del pasado siglo. Numerosos antimicrobianos y prácticas han sido ensayados para demostrar que el uso de antibióticos para el control de las bacterias aerobias y anaerobias, administrados por vía oral e intravenosa, logra la prevención de hasta el 75 por ciento de las infecciones del sitio quirúrgico en cirugía de colon. Las evidencias científicas orientan hacia la necesidad del uso de profilaxis antibióticos orales más intravenosas asociados a la preparación mecánica del colon(AU)

ABSTRACT Surgical site infections are a concern with respect to quality of health care. Surgical site infections are potentially preventable through the application of evidence-based prevention guidelines. The aim is to describe the historical evolution of practicing prophylactic use of antibiotics in colon surgery since the last century. We analyzed the literature published in the last five decades in MEDLINE, Infomed and other secondary sources. The evolution is highlighted of the combined use of antimicrobials (aminoglycosides, penicillin, cephalosporins, and nitroimidazoles) associated with the vigorous preparation of the colon in the 1970s of the last century. Numerous antimicrobials and practices have been tested to demonstrate that the use of antibiotics to control aerobic and anaerobic bacteria, administered orally and intravenously, achieves the prevention of up to 75 percent of surgical site infections in colon surgery. Scientific evidence points to the need for the use of more intravenous oral antibiotic prophylaxis associated with mechanical preparation of the colon(AU)

RESUMO

Introducción: Las infecciones del sitio quirúrgico pueden prevenirse con la aplicación de las mejores evidencias científicas, que incluyen como elemento clave la educación de los profesionales de la salud. Objetivo: Evaluar en qué medida se incluyen los aspectos relacionados con la prevención de las infecciones del sitio quirúrgico en los currículos de los estudiantes de la carrera de medicina y los residentes de cirugía general, y se abordan los conocimientos y las habilidades por parte de los profesores. Métodos: Estudio descriptivo y transversal, que contó con la revisión documental de los programas de formación de estudiantes y residentes. Además, se aplicó un cuestionario a 9 profesores de la asignatura Cirugía General de los hospitales clínico quirúrgicos "Joaquín Albarrán" y "Manuel Fajardo", durante mayo-junio de 2018. Resultados: En la rotación por cirugía general y en el internado médico se dejó explícito el objetivo de prevenir las infecciones del sitio quirúrgico, mientras en la residencia se hizo menos énfasis en el tema. La enseñanza de la higiene de las manos, la profilaxis antibiótica y la notificación de infecciones resultaron prioritarias. Se observaron diferencias en el abordaje de temas en estudiantes y residentes, y las prácticas de prevención seleccionadas no fueron abordadas sistemáticamente en ambos grupos de educandos. Las habilidades requeridas para la prevención de las infecciones del sitio quirúrgico se consideraron sistemáticamente por la mayoría de los docentes. Conclusiones: Se ha demostrado la existencia de brechas en los currículos formativos, y en el desarrollo de los conocimientos y las habilidades relacionados con la prevención de las infecciones del sitio quirúrgico en estudiantes de medicina y residentes de cirugía general(AU)

Introduction: Surgical site infections can be prevented with the application of the best scientific evidence, which includes, as a key element, the education of health professionals. Objective: To assess the extent to which aspects related to the prevention of surgical site infections are included into the curricula of medical students and of general surgery residents, and the extent to which knowledge and skills are addressed by professors. Methods: Descriptive and cross-sectional study, which included documentary review of the training programs for students and residents. In addition, a questionnaire was applied to nine professors of the subject General Surgery from Joaquín Albarrán Clinical-Surgical Hospital and Manuel Fajardo Clinical-Surgical Hospital, in the period from May to June 2018. Results: In the General Surgery rotation and in the medical internship, the objective of preventing surgical site infections was made explicit, while less emphasis on the subject was made in the residence. Teaching hand hygiene, antibiotic prophylaxis, and notification of infections were a priority. Differences were observed among students and residents regarding the way they address topics, while the prevention practices chosen were not systematically addressed in both groups of learners. The skills required for the prevention of surgical site infections were systematically considered by the majority of professors. Conclusions: The existence of gaps in training curricula was shown, as well as regarding the development of knowledge and skills related to the prevention of surgical site infections in medical students and General Surgery residents(AU)

RESUMO

BACKGROUND: The clinical characteristics of the most frequent arbovirosis (Dengue, Zika, Chikungunya) are very similar, which is a diagnostic challenge for clinicians. OBJECTIVE: To identify the presence of clinical characteristics related to Zika virus infection confirmed by the laboratory in patients during an epidemic of co-infection with Zika and Dengue viruses. METHOD: Cross-sectional descriptive study of patients with clinical - epidemiological suspicion of Zika virus infection, who were admitted in the Hospital "Joaquín Albarrán" (La Habana, Cuba), during June 1 to October 31 of 2017. Demographic and symptoms and signs were recorded. By PCR for Zika virus (in blood or urine) the disease was confirmed. RESULTS: 1541 patients were studied. The most frequent symptoms and signs were rash (93.8%), pruritus (77.9%), arthralgia (60.0%), headache (50.8%), myalgia (46.1%), fever (34.7%), asthenia (31.7%), and conjunctivitis (27.9%). Zika virus infection was confirmed in 279 patients (18.1%). Greater frequency of arthralgia, asthenia, and diarrhea was demonstrated in Zika confirmed patients. CONCLUSION: Minor clinical relevance was observed in the symptoms or signs of arboviral disease to support the clinical diagnosis of Zika virus infections by clinician during a Zika-Dengue epidemic. The assessment of the temporality of the onset of Zika and Dengue symptoms of these infections is recommended to assist clinicians in the differential diagnosis.
