Microbiota de la leche humana y su impacto en la salud humana.

Breast milk is a complex biological fluid. Additionally to its nutritional impact, it contains diverse bioactive elements related to early metabolic programming and molecular structures, such as microRNA related to the epigenetic signaling process. Now, we know that human milk is not sterile and contains a significant diversity of microorganisms such as bacteria (bacterioma), viruses (viroma) and fungi (mycobiome), all of which integrate the concept of the human milk microbiota. Apparently the origin of this microbiota is found in the entero-mammary circulation, as well as in the retrograde circulation of the skin of the mammary gland, although it is speculated in what percentage the microbiota of the oral cavity of the infant contributes in a significant way. From a functional point of view, it has been shown the transfer of this microbiota to the infant's digestive tract, which is related to better digestive tolerance, lower frequency and intensity of dysfunctionalities of the brain-intestine-microbiota axis, and improved immunity, among others.

La leche materna es un fluido biológico complejo, ya que además de nutrir, contiene diversos elementos bioactivos relacionados con el fenómeno de programación metabólica temprana e incluso contiene estructuras moleculares relacionadas con el proceso de señalización epigenética tales como los microARN. Ahora sabemos que la leche humana no es estéril y contiene una diversidad significativa de microorganismos tales como bacterias (bacterioma), virus (viroma) y hongos (micobioma), todo lo cual integra el concepto de microbiota de leche humana. Al parecer el origen de esta microbiota se encuentra en la circulación enteromamaria, así como en la circulación retrógrada de la piel de glándula mamaria, aunque se especula en qué porcentaje la microbiota de la cavidad bucal del lactante contribuye de forma significativa. Desde el punto de vista funcional, se ha demostrado transferencia de esta microbiota hacia el tubo digestivo del lactante, lo que se relaciona con una mejor tolerancia digestiva, menor frecuencia e intensidad de disfuncionalidades del eje cerebro-intestino-microbiota, y mejora de la inmunidad, entre otras.

[Tratamiento de infección crónica por virus de hepatitis C en niños, ¿perspectiva hacia la curación o lejos de la meta?]

La infección por el virus de hepatitis C es un problema global de salud pública; en México aproximadamente 2 % de la población se encuentra infectada. En niños, los datos de prevalencia son variables según la edad, pero se estima que 0.1 a 2 % de los niños presenta infección crónica por virus de hepatitis C, cuya principal vía de transmisión es la perinatal. Actualmente existen antivirales de acción directa aprobados en adultos con una tasa de respuesta viral sostenida superior a 95 %; sin embargo, en niños aún son pocos los estudios que confirman su seguridad y efectividad. Aunque todavía estamos lejos de la meta, avanzamos rápidamente hacia un tratamiento óptimo de curación también para pacientes pediátricos.

Infection with hepatitis C virus is a global health problem; in Mexico, approximately 2% of the population is infected. In children, data on prevalence are variable according to the age group, but 0.1-2% of children are estimated to have chronic infection with hepatitis C virus, the main way of transmission of which is perinatal. Currently, there are direct-acting antiviral agents approved in adults that offer a sustained viral response rate higher than 95%; however, in children there are still only few studies confirming their safety and effectiveness. Although we are still far from the goal, we are rapidly advancing towards an optimal curative treatment also for pediatric patients.

[Characterization of adolescents and reason for the visit when attending the pediatric emergency department of the General Hospital Dr. Manuel Gea González]. / Caracterización de los adolescentes y motivo de consulta por el que acuden al Servicio de Urgencias Pediátricas del Hospital General Dr. Manuel Gea González.

RATIONALE: Emergency health care demanded by adolescents has increased due to a variety of specific disorders. AIMS: (1) Describe the frequency of emergency services utilization by adolescents; (2) Identify the reason for the visit; (3) Describe psychosocial and health features of patients; and (4) Describe information related to informed assent. MATERIAL AND METHODS: Observational, descriptive, and prospective study carried out in patients aged 12 to 18 years, treated in the emergency department of General Hospital "Dr. Manuel Gea Gonzalez ", between 2008 and 2009. Survey data as well as the HEADSS sociodemographic questionnaire was used. RESULTS: A total of 170 patients were included in the study. The average age was 14.1 years; 55% were female. The main reasons for consultation were trauma (32.9%), followed by non-surgical gastrointestinal pathologies (12.4%), acute abdomen (11.8%), psychiatric emergencies (10.6%), neurological (8.8%), infectious or gynecologic obstetrical (both 8.2%). In 81% of cases, relatives (mostly parents) were the ones who decided to take the patient to the emergency room. It is noteworthy that in 64% of cases the patients had previously gone to the emergency room. Of the patients, 72.4% reported not having regular medical care and the remaining reported that medical care was referred to once or twice a year. CONCLUSIONS: Among patients seeking emergency care, a significant proportion are teenagers. The causes are varied, with care ranging from posttraumatic aspects to psycho-behavioral disorders. There is minimal culture in this age group to agree about their own treatment through informed consent.

[Efficacy and safety of ciprofloxacin treatment in urinary tract infections (UTIs) in adults: a systematic review with meta-analysis]. / Eficacia y seguridad de la ciprofloxacina en el tratamiento de las infecciones de las vías urinarias (IVU) en adultos: revisión sistemática con metaanálisis.

OBJECTIVES AND DESIGN: A systematic review with meta-analysis of randomized controlled trials (RGT) on the efficacy and safety of ciprofloxacin in the treatment of acute or complicated urinary tract infections in adults. Primary outcomes were bacteriological eradication, clinical cure, bacterial resistance, and adverse event rates. RESULTS: Initially, 111 RGTs were identified. We excluded 81 studies due to low quality methodology. An analysis of the remaining RGTs identified therapeutic equivalence of ciprofloxacin against other antimicrobials in terms of bacterial eradication and clinical cure at the end of treatment and in subsequent stages. The percentage of bacterial resistance was similar in both groups, while the percentage of related adverse events was significantly lower in the groups treated with ciprofloxacin. CONCLUSIONS: We conclude that ciprofloxacin is a safe and effective therapeutic alternative for the treatment of acute or complicated urinary tract infections in adults.

[Efficacy of racecadotril vs. smectite, probiotics or zinc as an integral part of treatment of acute diarrhea in children under five years: A meta-analysis of multiple treatments]. / Eficacia del racecadotrilo versus smectita, probióticos o zinc como parte integral del tratamiento de la diarrea aguda en menores de cinco años: meta-análisis de tratamientos múltiples.

RATIONALE: Despite major advances in treatment, acute diarrhea continues to be a public health problem in children under five years. There is no systematic approach to treatment and most evidence is assembled comparing active treatment vs. placebo. OBJECTIVE: Systematic review of evidence on efficacy of adjuvants for treatment of acute diarrhea through a network meta-analysis. METHODS: A systematic search of multiple databases searching clinical trials related to the use of racecadotril, smectite, Lactobacillus GG, Lactobacillus reuteri, Saccharomyces boulardii and zinc as adjuvants in acute diarrhea was done. The primary endpoint was duration of diarrhea. Information is displayed through network meta-analysis.The superiority of each coadjutant was analyzed by Sucra approach. RESULTS: Network meta-analysis showed race cadotril was better when compared with placebo and other adjuvants. Sucra analysis showed racecadotril as the first option followed by smectite and Lactobacillus reuteri. INTERPRETATION: Considering a strategic decision making approach, network meta-analysis allows us to establish the therapeutic superiority of racecadotril as an adjunct for the comprehensive management of acute diarrhea in children aged less than five years.

Probiotic improves symptomatic and viral clearance in Covid19 outpatients: a randomized, quadruple-blinded, placebo-controlled trial.

Intestinal bacteria may influence lung homeostasis via the gut-lung axis. We conducted a single-center, quadruple-blinded, randomized trial in adult symptomatic Coronavirus Disease 2019 (Covid19) outpatients. Subjects were allocated 1:1 to probiotic formula (strains Lactiplantibacillus plantarum KABP022, KABP023, and KAPB033, plus strain Pediococcus acidilactici KABP021, totaling 2 × 109 colony-forming units (CFU)) or placebo, for 30 days. Co-primary endpoints included: i) proportion of patients in complete symptomatic and viral remission; ii) proportion progressing to moderate or severe disease with hospitalization, or death; and iii) days on Intensive Care Unit (ICU). Three hundred subjects were randomized (median age 37.0 years [range 18 to 60], 161 [53.7%] women, 126 [42.0%] having known metabolic risk factors), and 293 completed the study (97.7%). Complete remission was achieved by 78 of 147 (53.1%) in probiotic group compared to 41 of 146 (28.1%) in placebo (RR: 1.89 [95 CI 1.40-2.55]; P < .001), significant after multiplicity correction. No hospitalizations or deaths occurred during the study, precluding the assessment of remaining co-primary outcomes. Probiotic supplementation was well-tolerated and reduced nasopharyngeal viral load, lung infiltrates and duration of both digestive and non-digestive symptoms, compared to placebo. No significant compositional changes were detected in fecal microbiota between probiotic and placebo, but probiotic supplementation significantly increased specific IgM and IgG against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) compared to placebo. It is thus hypothesized this probiotic primarily acts by interacting with the host's immune system rather than changing colonic microbiota composition. Future studies should replicate these findings and elucidate its mechanism of action (Registration: NCT04517422).Abbreviations: AE: Adverse Event; BMI: Body Mass Index; CONSORT: CONsolidated Standards of Reporting Trials; CFU: Colony-Forming Units; eDRF: Electronic Daily Report Form; GLA: Gut-Lung Axis; GSRS: Gastrointestinal Symptoms Rating Scale; hsCRP: High-sensitivity C-Reactive Protein; HR: Hazard Ratio; ICU: Intensive Care Unit; OR: Odds Ratio; PCoA: Principal Coordinate Analysis; RR: Relative Risk; RT-qPCR: Real-Time Quantitative Polymerase Chain Reaction; SARS-CoV2: Severe acute respiratory syndrome coronavirus 2; SpO2: Peripheral Oxygen Saturation; WHO: World Health Organization.

Noma and Noma-like disease in HIV/AIDS patients, a comorbid interaction: A systematic review.

INTRODUCTION: Noma is an opportunistic polymicrobial infection that cause necrosis of the mouth and face, with high morbidity and mortality, predominantly affecting malnourished children and persons with debilitating diseases. Cases of noma-like disease in adults, although rare, have been increasingly reported in HIV/AIDS patients particularly in developing countries but also in more developed countries. METHODOLOGY: A systematic review of the literature to assess the occurrence and clinical impact of noma and noma-like disease in HIV/AIDS patients was performed on PubMed, Virtual Health Library, Cochrane Library and Google Scholar using the keywords "HIV"[ All Fields] AND "Noma"[All Fields] in December 2016 (years includead for the search: 1985 to 2016). RESULTS: Twenty-four published studies were identified that document the occurrence of noma or noma-like disease in a total of 133 HIV/AIDS children and adult patients in the last 22 years. Although HIV infection is not the principal risk factor for noma, in some regions may play a substantial role in its pathogenesis. The mortality rate for noma-like disease in HIV/AIDS patients was 54.3%, compared to the 15% mortality rate of treated noma patients without HIV/AIDS. Most of the cases have never been on antiretroviral therapy, and their HIV infection was discovered because of the noma-like disease. CONCLUSIONS: The syndemic interaction between HIV/AIDS and noma-like disease adversely impacts the severity of the disease and the mortality rate. Noma-like disease, although not yet considered a specific or frequent disease associated with HIV infection, should be considered as an opportunistic infection for AIDS.

[Breaking bad news in the emergency room: Suggestions and future challenges]. / Comunicación de malas noticias en urgencias médicas: recomendaciones y retos futuros.

The aim of this paper is to describe educational programs that reportedly teach how to break bad news in the emergency department. We also suggest some recommendations on how to communicate bad news based on the research of evidence available in the field. The examined evidence points toward six major components with which physicians should familiarize when communicating bad news: 1) doctor-patient empathic communication, 2) establishing a proper space to give the news, 3) identifying characteristics of the person who receives the news, 4) essential aspects for communicating the news; 5) emotional support, and 6) medical and administrative aspects of the encounter. Finally, we point out several limitations in the studies in the field and future challenges identified in the communication of bad news in emergency room facilities.

El objetivo del presente trabajo es reseñar una descripción de los programas educativos que incluyen el entrenamiento de la comunicación de malas noticias a médicos pertenecientes al departamento de urgencias. Además se hacen recomendaciones sobre cómo dar malas noticias con base en la evidencia de investigación hasta ahora disponible en las áreas de urgencias. De acuerdo con la información obtenida, es factible identificar seis grandes áreas con las que el médico requiere familiarizase cuando comunica malas noti cias: 1) comunicación empática médico-paciente, 2) preparación del ambiente para dar la noticia, 3) identificación de las características de quien recibe la noticia, 4) aspectos indispensables al comunicar la noticia, 5) manejo de reacciones emocionales y 6) aspectos médicos, administrativos y del cierre del encuentro. Finalmente, se describen las limitaciones que parecen caracterizar a los estudios en el área y se señalan los retos futuros en la comunicación de malas noticias en urgencias médicas.

Efficacy of Lactobacillus reuteri DSM 17938 for infantile colic: Systematic review with network meta-analysis.

BACKGROUND: 5% to 40% of infants cry excessively, usually accompanied by fussiness and excessive of gas. There are no uniform criteria for treatment of infantile colic. Lactobacillus reuteri DSM 17938 has been used with promising results. The objective of this network-meta-analysis (NMA) is to compare the efficacy of L reuteri DSM 17938 with other interventions for infantile colic. METHODS: RCTs, published between 1960 and 2015 for the treatment of infantile colic were included. Primary outcome was duration of crying after 21 to 28 days of treatment. Different databases were searched. Information was analyzed using control group as central axis. A random effect model was used. Hedges standard mean difference (SMD) and odds ratio (OR) were calculated. A SUCRA analysis was performed to evaluate superiority for each intervention. RESULTS: 32 RCTs were analyzed, including 2242 patients. Studies with L reuteri DSM 17938 versus Ctrl., Diet versus Ctrl. and Acupuncture versus Ctrl. were the most influential studies in the NMA. L reuteri DSM 17938 [WMD -51.3 h (CI95% -72.2 to -30.5 h), P .0001] and dietetic approaches [WMD -37.4 h (CI95% -56.1 to -18.7 h), P .0001] were superior compared to the other treatments. CONCLUSIONS: L reuteri DSM 17938 and some dietetic approaches are better to other interventions for treatment of infantile colic.

Descending necrotizing mediastinitis: Systematic review on its treatment in the last 6 years, 75 years after its description.

BACKGROUND: Descending necrotizing mediastinitis is a serious infection involving the neck and the chest, in which an odontogenic, pharyngeal, or cervical infection spreads rapidly to the thoracic cavity, with a high death rate by sepsis and organic failure if not treated quickly and properly. METHODS: A systematic search in the electronic database PubMed was conducted using the keywords "mediastinitis" and "descending necrotizing mediastinitis" resulting in 2560 items, filters were activated (systematic review, meta-analysis, and clinical trial) resulting in 60 articles, from which we selected relevant articles on the topic. RESULTS: The best available evidence we could obtain was from 26 case series with evidence level III. The overall mortality in this period was 17.5%. CONCLUSION: For mediastinitis limited to the upper part of the mediastinum, transcervical drainage may be sufficient; cases that extended below the tracheal carina may require cervical and transthoracic drainage. A multidisciplinary therapeutic approach has allowed a reduction in its mortality. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2275-E2283, 2016.

Myocutaneous sternocleidomastoid flap for reconstruction after the resection of a parapharyngeal heterotopic glioma in a child with cleft palate, and systematic review of parapharyngeal glial heterotopia.

We describe the surgery and reconstruction employed with a sternocleidomastoid myocutaneous flap for the treatment of a heterotopic glioma in a 2-year-old boy with incomplete palatal fissure who presented with dysphagia and snoring, in whom a lateral pharyngeal wall mass obstructing 60% of the airway was noted. Heterotopic gliomas are uncommonly reported in the parapharyngeal space and should be included in the differential diagnosis at this location in children. Parapharyngeal tumors present difficult diagnostic and management challenges; head and neck surgeons must be prepared not only for the resection but also for the reconstruction of these rare lesions.

Association of vitíligo and autoimmune thyroiditis disease in a male adolescent with obesity / Asociación de vitiligo y tiroiditis crónica autoinmune en adolescente masculino con obesidad

El vitíligo es el trastorno despigmentante adquirido más frecuente, con una prevalencia mundial del 0.5-2%. Su mayor incidencia se produce entre los 10 y 30 años. Se asocia a trastornos tiroideos autoinmunes con presencia de anticuerpos antitiroperoxidasa hasta en un 20%. Se presenta el caso de masculino de 15 años de edad, diagnosticado con vitíligo a los 10 años de edad con seguimiento por dermatología, actualmente en tratamiento. El paciente se encuentra en seguimiento médico por obesidad. Se ha descrito asociación positiva entre vitiligo y tiroiditis autoinmune, duplicando el riesgo a los cinco años de diagnóstico concomitante a patología autoinmune previa. Teniendo en cuenta que el vitiligo precede generalmente al inicio de la disfunción tiroidea, el seguimiento periódico de pacientes con vitiligo es de gran importancia.

Vitiligo is the most common acquired depigmentation disorder with a worldwide prevalence from 0.5 to 2%. It is highest incidence occurs between the ages of 10 to 30 years old. Frequently, it is associated with autoimmune thyroid disorders and related to the presence of anti-thyroid peroxidase antibodies in 20% of the times. We present the case of 15 years old male, diagnosed with vitiligo at 10 years old with currently dermatology follow up under treatment. The patient is in medical monitoring due to obesity. It has been described an association between Vitiligo and Thyroiditis, doubling the risk of presence in five years from the concomitant diagnose to a previous autoimmune pathology. Considering that vitiligo usually precedes the onset of thyroid dysfunction, periodic monitoring in patients with this disorder it is of great importance.

Estudio de la eficacia y seguridad de brodimoprim vs. trimetoprim-sulfametoxazol en niños con gastroenteritis bacteriana / Study brodimoprim vs. trimetoprim-sulfatoxasol security and effectiveness in children with bacterial gastroenteritis

Se realizó un estudio comparativo de brodimoprim contra trimetoprim/sulfametoxazol para el tratamiento de niños con diarrea aguda bacteriana. Se estudiaron 30 pacientes en cada grupo. El grupo l recibió trimetoprim/sulfametoxazol en suspensión por vía oral, a dosis de 8 mg/kg/día cada 12 horas por 5 días. El grupo ll recibió brodimoprim en suspensión con dosis única inicial de 10 mg/kg de peso, seguida de 5 mg/kg cada 24 horas por 5 días. En ambos grupos, los resultados mostraron remisión de la sintomatología en todos los pacientes, y negativización en la mayoría de los coprocultivos. En efectos colaterales un paciente presentó cefalea y otros dos presentaron diarrea por brodimoprim; la diferencia no fue significativa. Se concluye que brodimoprim es una buena alternativa para tratar a niños con diarrea aguda.

Cistadenoma de vías biliares / Cystadenoma of the biliary tract

Se presenta el caso de un adolescente del sexo masculino de 12 años de edad, con diagnóstico de cistadenoma de vías biliares intrahepáticas. Se hace una revisión de la literatura y se hace notar que hay menos de 100 casos publicados hasta el momento. Todos ellos en individuos mayores de 14 años de edad

Alimentación parenteral cíclica en niños con alimentación parenteral continua / Cyclic parenteral feeding in childrens with continuous parenteral feeding

Se presenta la experiencia obtenida con la alimentación parenteral cíclica (APC) dada a siete pacientes con desnutrición marasmática, e imposibilidad para mejorar su estado nutricio. Todos los niños recibieron alimentación parenteral totla (APTC) dudante doce horas obturando luego el catéter con solución salina heparinizada. Los pacientes recibieron 22 ñ 5.4 días de APC; todos mejoraron su estado nutricio. Seis de los siete presentaron, al inicio, hipoalbuminemia que se corrigió con la APC. Cinco presentaron colestasis y sólo dos continuaron con el problema después de la APC. Tres pacientes tuvieron hipertrigliceridemia; uno, hiperglucemia y en ninguno se observó hipoglucemia. En todos mejoró el índice creatinina/talla y el balance de nitrógenos se hizo positivo. En cuatro se presentó extracción accidental del catéter y en uno infección del sitio de inserción. Los hallazgos sugieren que al APC es útil para disminuir las complicaciones hepáticas producidas por la APTC; además mejora la concentración de albúmina. Las complicaciones inherentes al método son mínimas pudiendo reducirse aún más con vigilancia especial del paciente durante el periodo libre de administración de nutrimentos

Hidratación endovenosa rápida en lactantes con diarrea aguda y deshidratación / Intravenous rehidratation in children with dehydration for acute diarrhea

Objetivo: Comparar dos esquemas de hidratación endovenosa en niños con deshidratación por diarrea aguda. Material y métodos: Ochenta y tres niños con diarrea aguda y deshidratación, que tuvieron intoleracia a la hidratacion oral, se distribuyeron de manera aleatoria en dos grupos; el control recibió un esquema rutinario de hidratación en 24 horas, basado en pérdidas previas y cálculo de requerimiento para 24 horas con solución glucosada al 5 por ciento (SG), y solución fisiológica (SF); el grupo de estudio, recibió una solución mixta (SG:SF) a razón de 25 Ml/kg/hora hasta conseguir su hidratación completa. Resultados: no hubo diferencias entre ambos grupos al comparar: edad, sexo, antecedentes del cuadro enteral, grado de deshidratación y estudios de laboratorio iniciales. El tiempo de rehidratación fue más rápido en el grupo de estudio. Conclusión: Los resultados sugieren que un esquema rápido de rehidratación endovenosa es tan efectivo como el método tradicional, con la ventaja que disminuye la estancia hospitalaria y permite el inicio más temprano de la vía oral
