Implementation of an integrated care strategy for child contacts of tuberculosis patients: a quasi-experimental study protocol.

BACKGROUND: Childhood tuberculosis continues to be a major public health problem. Although the visibility of the epidemic in this population group has increased, further research is needed. OBJECTIVE: To design, implement and evaluate an integrated care strategy for children under five years old who are household contacts of bacteriologically confirmed pulmonary tuberculosis patients in Medellín and the Metropolitan Area. METHODS: A quasi-experimental study in which approximately 300 children who are household contacts of bacteriologically confirmed pulmonary tuberculosis patients from Medellín and the Metropolitan Area will be evaluated and recruited over one year. A subgroup of these children, estimated at 85, who require treatment for latent tuberculosis, will receive an integrated care strategy that includes: some modifications of the current standardized scheme in Colombia, with rifampicin treatment daily for four months, follow-up under the project scheme with nursing personnel, general practitioners, specialists, professionals from other disciplines such as social work, psychology, and nutritionist. Additionally, transportation and food assistance will be provided to encourage treatment compliance. This strategy will be compared with isoniazid treatment received by a cohort of children between 2015 and 2018 following the standardized scheme in the country. The study was approved by the CIB Research Ethics Committee and UPB. CLINICALTRIALS: gov identifier NCT04331262. DISCUSSION: This study is expected to contribute to the development of integrated care strategies for the treatment of latent tuberculosis in children. The results will have a direct impact on the management of childhood tuberculosis contributing to achieving the goals proposed by the World Health Organization's End TB Strategy.

A global point prevalence survey of antimicrobial use in neonatal intensive care units: The no-more-antibiotics and resistance (NO-MAS-R) study.

BACKGROUND: Global assessment of antimicrobial agents prescribed to infants in the neonatal intensive care unit (NICU) may inform antimicrobial stewardship efforts. METHODS: We conducted a one-day global point prevalence study of all antimicrobials provided to NICU infants. Demographic, clinical, and microbiologic data were obtained including NICU level, census, birth weight, gestational/chronologic age, diagnoses, antimicrobial therapy (reason for use; length of therapy), antimicrobial stewardship program (ASP), and 30-day in-hospital mortality. FINDINGS: On July 1, 2019, 26% of infants (580/2,265; range, 0-100%; median gestational age, 33 weeks; median birth weight, 1800 g) in 84 NICUs (51, high-income; 33, low-to-middle income) from 29 countries (14, high-income; 15, low-to-middle income) in five continents received ≥1 antimicrobial agent (92%, antibacterial; 19%, antifungal; 4%, antiviral). The most common reasons for antibiotic therapy were "rule-out" sepsis (32%) and "culture-negative" sepsis (16%) with ampicillin (40%), gentamicin (35%), amikacin (19%), vancomycin (15%), and meropenem (9%) used most frequently. For definitive treatment of presumed/confirmed infection, vancomycin (26%), amikacin (20%), and meropenem (16%) were the most prescribed agents. Length of therapy for culture-positive and "culture-negative" infections was 12 days (median; IQR, 8-14) and 7 days (median; IQR, 5-10), respectively. Mortality was 6% (42%, infection-related). An NICU ASP was associated with lower rate of antibiotic utilization (p = 0·02). INTERPRETATION: Global NICU antibiotic use was frequent and prolonged regardless of culture results. NICU-specific ASPs were associated with lower antibiotic utilization rates, suggesting the need for their implementation worldwide.

Human Herpes Virus 6 Detection in Children With Suspected Central Nervous System Infection.

Human herpes virus 6 (HHV-6) infection is considered a self-limited disease in immunocompetent children. However, HHV-6 could be associated with various neurologic diseases. We describe 8 children with suspected central nervous system infection and detection of HHV-6 in cerebrospinal fluid. The clinical significance of HHV-6 detection is controversial because it may be caused by primary infection, reactivation or latency.

Comportamiento de un modelo de predicción de infección bacteriana invasiva en niños con cáncer, neutropenia y fiebre / Performance of a predictive model for invasive bacterial infection, in children with cancer, neutropenia and fever

Objetivo: Describir el comportamiento de un modelo de predicción de infección bacteriana invasiva en niños con cáncer que cursan con neutropenia y fiebre, atendidos en el Hospital Infantil San Vicente Fundación (HISVF), en el año 2017. Materiales y métodos: Estudio descriptivo, de corte transversal y de período, que incluyó pacientes menores de 14 años con diagnóstico de algún tipo de cáncer que ingresaron al HISVF entre enero y diciembre de 2017, con diagnóstico de neutropenia y cuadro febril. Resultados: Se encontraron 99 episodios en 44 pacientes con NF. Al analizar la muestra según el grupo de riesgo estratificado y el desenlace aislamiento microbiológico o muerte, se encontraron diferencias entre los dos grupos. Estas diferencias muestran una mayor mortalidad y frecuencia de infección bacteriana invasiva en los pacientes clasificados como de alto riesgo. Discusión: La aplicación de estos criterios puede ser usada para un mejor direccionamiento del enfoque terapéutico incluyendo: el uso racional de antibióticos y un alta temprana o un seguimiento ambulatorio.

Objective: To describe the behavior of a predictor model of invasive bacterial infection in children with neutropenia and fever in Hospital Infantil San Vicente Fundación (HISVF by its name in Spanish), throughout the year of 2017. Material and method: Descriptive, cross-sectional study, which included patients under 14 years of age with a diagnosis of some type of cancer that attended HISVF in the period of time from January to December in 2017, with a diagnosis of neutropenia and fever. Results: 99 episodes were found in 44 patients diagnosed with neutropenia and fever. According to the stratified risk group and the outcome of microbiological isolation or death, differences were found between the two groups. Discussion: The application of these criteria can be used to improve therapeutic approach and impact in rational use of antibiotics and early discharge.

Acute Infectious Diarrhea and Gastroenteritis in Children.

PURPOSE OF REVIEW: We aimed to summarize the most current evidence on the main aspects of the diarrheal diseases in children. The following key elements were addressed: definitions, etiology, pathogenesis, diagnosis, dietary management, pharmacological treatments, and prevention. We covered the following questions: What are the most important clinical and laboratory features of the disease? What are the best approaches for the dietary management? What is the best way to classify the hydration status, and to prevent and treat the dehydration? What are the most effective and safe interventions for reducing the diarrhea and vomiting? RECENT FINDINGS: Diarrheal diseases are one of the most common diseases in childhood. The most common cause is rotavirus. A key element in the approach of a child with diarrhea is determining their hydration status, which determines the fluid management. Laboratory tests are nor routinely required, as most of the cases, they do not affect the management and it should be indicated only in selected cases. Several treatments have been studied to reduce the duration of the diarrhea. Only symbiotics and zinc have shown to be effective and safe with high certainty on the evidence. Rest of the interventions although seem to be effective have low to very low quality of the evidence. The only effective and safe antiemetic for controlling vomiting is ondansetron. A list of antimicrobials indications according to the identified microorganisms is provided. We summarized the most current evidence on diagnosis, management, and prevention of diarrhea in children. More research is needed in some areas such as dehydration scales, rehydration management, antidiarrheals, and antibiotic treatments.

Linfoma de Burkitt en un escolar con infección perinatal por VIH lentamente progresiva / Burkitt's lymphoma in a school boy with slow progression perinatally acquired HIV

Resumen Las manifestaciones clínicas en los niños con infección por el virus de la inmunodeficiencia humana (VIH) de transmisión perinatal, pueden ser de inicio precoz o tardío. El linfoma asociado a VIH es una manifestación tardía que se asocia a estadios avanzados de inmunosupresión. Se presenta el caso de un escolar de 9 años con diagnóstico de novo de infección por VIH que debutó con un linfoma de Burkitt. En niños, la frecuencia de esta asociación es de 1-2% con pocos casos reportados en la literatura médica.

Children with perinatal human immunodeficiency virus (HIV) infection can present early or late clinical disease. HIV-associated lymphoma is a later manifestation that is associated with advanced immunosuppression (acquired immunodeficiency syndrome -AIDS). This is a case of a 9-year-old boy with recent diagnosis of HIV with Burkitt's lymphoma as first clinical manifestation. In children, the frequency of this association is very low and there are few cases reported.
