Frequency of hand contact with hospital surfaces in hospitalized pediatric patients.

Background: Hand hygiene (HH) is an important strategy for preventing health-care-associated infections (HAIs). Few programs focus on HH for family members and primary caregivers but fewer for patients. This study aimed to estimate the frequency with which hospitalized pediatric patients have hand contact with hospital surfaces.

Burnout and Its Relationship with Work Engagement in Healthcare Professionals: A Latent Profile Analysis Approach.

The aim of this study was to use latent profile analysis to identify specific profiles of burnout syndrome in combination with work engagement and to identify whether job satisfaction, psychological well-being, and other sociodemographic and work variables affect the probability of presenting a profile of burnout syndrome and low work enthusiasm. A total of 355 healthcare professionals completed the Spanish Burnout Inventory, the Utrecht Work Engagement Scale, the Job Satisfaction Scale, and the Psychological Well-Being Scale for Adults. Latent profile analysis identified four profiles: (1) burnout with high indolence (BwHIn); (2) burnout with low indolence (BwLIn); (3) high engagement, low burnout (HeLb); and (4) in the process of burning out (IPB).

Positive Mental Health Questionnaire (PMHQ) for Healthcare Workers: A Psychometric Evaluation.

The Positive Mental Health Questionnaire (PMHQ) has been validated across various populations but has displayed diverse psychometric structures depending on the procedures used. The original version of the PMHQ includes 39 items organized into 6 factors, although there are reports that indicate a reduced structure of between 1 and 4 factors. The aim of this study was to assess the psychometric properties of the PMHQ with 1, 4 and 6 factors.

Immunostimulants for preventing respiratory tract infection in children: A systematic review and meta-analysis.

Childhood acute respiratory tract infections (ARTIs) are a significant cause of morbidity and mortality, so, immunostimulants have been used as a preventative measure. Despite this, there is no updated evidence regarding the safety and efficacy of immunostimulant drugs for this purpose. This study aimed to determine the effectiveness and safety of immunostimulants in preventing ARTIs in children based on the most recent scientific evidence.

Tracing COVID-19 Source of Infection Among Health Personnel in a Pediatric Hospital.

Health personnel (HP) have been universally recognized as especially susceptible to COVID-19. In Mexico, our home country, HP has one of the highest death rates from the disease. From the beginning of the SARS-CoV-2 pandemic, an office for initial attention for HP and a call center were established at a COVID-19 national reference pediatric hospital, aimed at early detection of COVID-19 cases and stopping local transmission.

Characteristics and Outcomes of Cases of Children and Adolescents With Pediatric Inflammatory Multisystem Syndrome in a Tertiary Care Center in Mexico City.

Background: Pediatric inflammatory multisystem syndrome (PIMS) is a complication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children that resembles Kawasaki syndrome and places them at high risk of cardiorespiratory instability and/or cardiac damage. This study aims to describe the clinical presentation and outcomes of patients with PIMS in Mexico City.

Methods: This was an observational study of children hospitalized for PIMS based on the Centers for Disease Control and Prevention case definition criteria, in a single tertiary care pediatric center in Mexico City between May 1, 2020, and September 30, 2021.

Association of Genetic Polymorphisms and Serum Levels of IL-6 and IL-8 with the Prognosis in Children with Neuroblastoma.

There is evidence that high circulating levels of IL-6 and IL-8 are markers of a poor prognosis in various types of cancer, including NB. The participation of these cytokines in the tumor microenvironment has been described to promote progression and metastasis. Our objective was to evaluate the prognostic role of genetic polymorphisms and serum levels of IL-6 and IL-8 in a cohort of Mexican pediatric patients with NB.

Restructuring of a pediatric hospital in the face of the COVID-19 pandemic.

Overview of the pandemic In December 2019, a new virus named SARS-CoV-2 was reported in Wuhan province, China. The first case of COVID-19 in Mexico was confirmed on February 28, 2020, and the World Health Organization declared the pandemic on March 11.

Objective: To provide epidemiological information on the delay in the diagnosis of PID and its correlation to chronic lung damage.

Material And Method: A retrospective, analytical study was done in patients 0-18 year old age diagnosed with PID for 11 years at the HIMFG (Hospital Infantil de Mexico Federico Gomez).

[Antihistamines for the treatment of urticaria in Mexico].

There are four types of histamine receptors. Allergic symptoms, especially those in rhinoconjunctivitis and urticaria, are mainly caused by activation of histamine receptor 1 (H1). Consequently, oral H1-antihistamines form and integral part of the treatment of these diseases.

[Mexican guidelines on the diagnosis and treatment of urticaria].

Background: Urticaria is a disease that a fifth of the population shallsuffer once in a lifetime. Recent clinical guidelines have proposed some fundamental changes in the diagnosis and treatment of urticaria, making the development of a national, multidisciplinary guideline, with wide acceptability among different professional groups -both specialists and primary health care workers-, necessary in Mexico.

Material And Method: Internationally recognized tools for guidelinedevelopment were used.

[Food allergy].

Food allergy is defined as an abnormal immunological reaction to food proteins, which causes an adverse clinical reaction. Most of the people become tolerant to many foods; however some time these tolerances fail and become an immunologic reaction. This is the first clinical expression of allergy, beginning with dermal o gastric manifestations and continues with asthma and rhinitis (the allergy march) and represents a very severe health problem, not only for many children and parents, but also for the entire medical and paramedical community.

[Risk factors of food allergy].

Food allergy or allergic food hypersensitivity is defined as an adverse immunologic reaction caused by immunologic mechanisms mediated or not by IgE. It is a complex disease influenced by polygenetic heritance and environmental factors. Many risk factors have been investigated, pre natal and post natal, and variable and controversial results have been obtained.

[Difficult-to-control asthma. A bibliographical review].

Difficult-to-control asthma is a disease that causes serious exacerbations, near-fatal attacks, frequent hospitalizations, and needs chronic use of high doses of inhaled corticosteroids or daily oral corticosteroid therapy. On the basis of epidemiological studies, the risk factors for serious asthma are: female gender, high BMI, sensitivity to aspirin, gastro esophageal reflux, sinusitis, pneumonia history, and beginning of asthma symptoms in adult late age. It has been found that in severe asthma the inflammatory profile commonly changes with major participation of neutrophils, and evidence of destruction and remodelling.

[Diagnosis and treatment in the emergency room of acute asthma in childhood].

Acute asthma is characterized by acute air way obstruction episodes presented as short breath, increased coughing, wheezing and difficult breathing, reversible with bronchodilator. It constitutes one of the most frequent causes of pediatric ER visits whose diagnosis and treatment is not always adequate. It is necessary to carry out a complete medical history searching for the number of previous attacks, risk factors, associated illnesses, triggers, prior hospitalizations, preventive and maintenance treatment used, along with a complete physical examination.

[Uncommon manifestations of atopic dermatitis].

Atopic dermatitis is an inflammatory process characterized by a series of cutaneous alterations of typical morphology and distribution, with intense pruritus of nocturnal predominance, of chronic evolution, stational appearance, and with personal and family history of atopy. On genetically predisposed skin, dry and hypersensitive, the immune factors and other types are implicated in determining the abnormal reactions to multiple endogenous and environmental factors. The diagnosis is clinical, generally obtained by a group of signs and symptoms known as the Hanifin and Rajka criteria.

[Adverse reactions to vaccines].

Vaccination is one of the medicine's achievements to control and/or eradicate certain infectious diseases. Vaccines contain antigenic doses derived from microorganisms and/or its toxins, besides they are composed of other substances such as aluminum, gelatin, egg proteins, mercury components (as thimerosal), and antibiotics; therefore, these substances can produce hypersensitivity reactions. The above-mentioned reactions can be evidenced with itch, edema, hives, asthmatic crisis, hypotension and even anaphylactic shock.

[Urticaria and angioedema].

Urticaria is considered a heterogeneous group of diseases that share different patterns of skin reactions. The wide diversity in urticaria subtypes have been identified and this reflects partial understanding of the causes or factors that trigger it, as well as the molecular and cellular mechanisms that are involved in their physiopathology. The objective of this article was to make an extensive review of the literature to be able to offer the readers a complete information and updating on the basic, ethiologic and physiophatologic mechanisms and mainly to make a special emphasis on diagnosis and treatment of urticaria, promoting the continuous medical education.

[Allergic conjunctivitis in children].

Allergic conjunctivitis is a group of diseases that are frequent in childhood, associated to several allergic diseases affecting the ocular surface. It is related to type 1 hypersensitivity reactions. Two acute disorders: seasonal allergic conjunctivitis and perennial allergic conjunctivitis, exist, as do three chronic diseases: vernal keratoconjunctivitis, atopic keratoconjunctivitis and giant papillary conjunctivitis.

[Anaphylaxis and anaphylactic shock].

Term anaphylaxis means an immediate hypersensitivity reaction mediated by IgE that produces a clinical syndrome with systemic affection of variable severity. Its prevalence varies according to the habits of each region and of the studied population from 3.2 to 7.

Asthma prevalence in children living in north Mexico City and a comparison with other Latin American cities and world regions.

Reports of previous studies done without following the international guidelines in different cities of Mexico showed a decrease in asthma prevalence. The aim of this study was to determine the prevalence and severity of asthma symptoms in children and teenagers living in north Mexico City and compare them with those of other Latin American cities and world regions. The cross-sectional survey followed the protocol of the International Study of Asthma and Allergies in Childhood IIIb phase survey.

Identification of asthma risk factors in Mexico City in an International Study of Asthma and Allergy in Childhood survey.

The International Study of Asthma and Allergy in Childhood (ISAAC) has assessed the prevalence of asthma, as well as the factors related to the disease in different countries. The aim of this study was to identify asthma risks factors in Mexico City. Data were obtained from questionnaires of children participating in a phase 3b ISAAC survey.

[Cow-milk's protein allergy].

Milk contains more than 40 proteins and all of them may act like human species antigens. The main allergens are beta lactoglobulin, casein, alpha lactoalbumin and seroalbumin; beta lactoglobulin is a protein not existing in human species and is found in maternal milk in minimal quantities (mcg) due to milky products ingested by the mother, these small quantities are responsible of the highest number of sensitizations to this protein. This article reviews the allergy to the cow-milk's protein, also, a critical route to its diagnosis and management is planted.
