Posición técnica sobre la leche y derivados lácteos en la salud y en la enfermedad del adulto de la Asociación Mexicana de Gastroenterología y la Asociación Mexicana de Gerontología y Geriatría

Milk is a liquid food that possesses an important quantity of highly bioavailable macronutrients. In addition, it is readily accessible, as well as relatively inexpensive. Given that the knowledge of physicians about nutrition and food composition is deficient, in general, many of the dietary interventions recommended in diverse clinical settings lack a scientific basis. The aim of the present review was to produce a technical opinion that serves as a frame of reference to best sustain recommendations for consuming milk and dairy products as daily nutrition in the adult and older adult. The effects of milk and dairy products during the pediatric stage are not addressed in the present work. The Asociación Mexicana de Gastroenterología and the Asociación Mexicana de Gerontología y Geriatría jointly discussed and analyzed topics dealing with the legal designation of milk, the classification and nutritional profile of cow's milk, its nutritional characteristics, its consumption in the adult, intolerance to cow's milk, and associations of milk consumption with digestive tract alterations and other conditions. Finally, certain aspects of milk consumption in the older adult and its relation to overall health are briefly discussed.     

Posición técnica de la Asociación Mexicana de Gastroenterología sobre las bebidas vegetales a base de soya

There has been a recent increase in the consumption of cow's milk substitutes, specifically plant-based beverages, which have erroneously been named “plant milks”. Plant-based beverages do not have a standard of identity, and so their nutritional composition can vary from one brand to another, even within the same category. The aim of the present narrative review was to produce a technical opinion to serve as a frame of reference for sustaining the recommendation of soy plant-based beverages. Nutrition and gastroenterology experts that belong to the Asociación Mexicana de Gastroenterología jointly commented on and analyzed themes on plant-based beverages, and on soy drinks in particular, including their nutritional characteristics, consumption in children, and potential growth and development alterations, as well as soy drink consumption in adults and its association with gastrointestinal alterations and other conditions. Plant-based beverages, including those made from soy, are not a replacement for breastmilk or breastmilk substitutes. Soy beverages are considered safe and can enrich the varied diet of its consumers, as long as they are considered an additional liquid portion of the diet. They can be ingested by adults and children above two years of age that present with cow's milk protein allergy or lactose intolerance.     

Peniciliosis endobronquial: presentación de un caso y revisión de la literatura

Penicilliosis is an opportunistic infection in HIV-infected and other immunocompromised patients mostly in Southeast Asia, Southern China, Hong Kong, and Taiwan, with respiratory manifestations in about one-third of patients. We report the case of a 26-year-old non-HIV immunocompromised patient presenting with an airway obstruction caused by penicilliosis, together with a review of the literature of this rare condition.     

Consenso sobre el diagnóstico y el tratamiento de la alergia a las proteínas de la leche de vaca de la Sociedad Latinoamericana de Gastroenterología,Hepatología y Nutrición

Cow's milk protein allergy (CMPA) is the most frequent cause of food allergy in the first months of life. Despite the fact that there are different guidelines and recommendations on the management of children with CMPA, there continues to be great variability in diagnostic and therapeutic criteria in Latin America. The Food Allergy Working Group of the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition summoned a group of Latin American experts to reach a consensus and formulate a document to unify diagnostic and therapeutic criteria for CMPA. Three teams were formed, each with a coordinator, and the members of each team developed a series of statements for their corresponding module: a) clinical manifestations and diagnosis; b) diagnostic tools, and c) treatment. A search of the medical literature was carried out to support the information presented in each module and 28 statements were then selected. The statements were discussed, after which they were evaluated by all the experts, utilizing the Delphi method. Their opinions on statement agreement or disagreement were anonymously issued. The final statements selected were those with above 75% agreement and their corresponding recommendations were formulated, resulting in the document presented herein.     

Consenso de alimentación complementaria de la Sociedad Latinoamericana de Gastroenterología,Hepatología y Nutrición Pediátrica: COCO 2023

Complementary feeding (CF) is defined as the feeding of infants that complements breastfeeding, or alternatively, feeding with a breast milk substitute, and is a process that is more than simply a guide as to what and how to introduce foods. The information provided by healthcare professionals must be up-to-date and evidence-based. Most of the recommendations that appear in the different international guidelines and position papers are widely applicable, but some must be regionalized or adapted to fit the conditions and reality of each geographic zone. The Nutrition Working Group of the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition (LASPGHAN) summoned a group of experts from each of the society's member countries, to develop a consensus on CF, incorporating, whenever possible, local information adapted to the reality of the region. The aim of the present document is to show the results of that endeavor. Utilizing the Delphi method, a total of 34 statements on relevant aspects of CF were evaluated, discussed, and voted upon.     

Carcinoma basocelular de la región perianal: reporte de un caso y revisión de la literatura

The literature reports an annual incidence of 5,900 cases of anal cancer in the developed countries. These involve three different anatomic zones: carcinoma of the anal canal, perianal carcinoma (formerly known as carcinoma of the anal margin, located at a distance of less than 5 cm from the anal margin), and carcinoma of the perianal skin (at a distance greater than 5 cm from the anal margin). Basal cell carcinoma of the perianal region is an uncommon tumor (0.27% of all diagnosed basal cell carcinomas) that in the majority of cases is treated by resection with disease-free margins. It must be differentiated from the basaloid and epidermoid variants of carcinoma, given that it has good outcome and its spread potential is practically null.     

Asociación Mexicana de Hepatología A.C. Guía Clínica de Hepatitis B

Hepatitis B virus (HBV) infection continues to be a worldwide public health problem. In Mexico, at least three million adults are estimated to have acquired hepatitis B (total hepatitis B core antibody [anti-HBc]-positive), and of those, 300,000 active carriers (hepatitis B surface antigen [HBsAg]-positive) could require treatment. Because HBV is preventable through vaccination, its universal application should be emphasized. HBV infection is a major risk factor for developing hepatocellular carcinoma. Semi-annual liver ultrasound and serum alpha-fetoprotein testing favor early detection of that cancer and should be carried out in all patients with chronic HBV infection, regardless of the presence of advanced fibrosis or cirrhosis. Currently, nucleoside/nucleotide analogues that have a high barrier to resistance are the first-line therapies.     

Artropatía destructiva de grandes articulaciones y calcinosis tumoral asociada a oxalosis primaria: reporte de un caso y revisión de la literatura

A case of destructive arthropathy of hips and shoulders with tumoral calcinosis associated with calcium oxalate deposits in a patient with primary oxalosis and end stage renal disease on hemodialysis.     

Manifestaciones neurológicas de la enfermedad de Behçet: descripción de un caso y revisión de la literatura

Neurological involvement in Behçet's disease is rare, especially at the onset. It can present in the form of parenchymal changes or as damage to the vascular structures in its nonparenchymal form. The coexistence of both kinds of manifestations in the same patient is exceptional. We report the case of a 32-year-old patient with a history of deep venous thrombosis, who was being treated for holocranial headache, apathy, and oral and genital ulcers. Brain magnetic resonance imaging showed hyperintense lesions in the basal ganglia and white matter, and the vascular study evidenced venous thrombosis of the left transverse sinus. After confirming the diagnosis of Behçet's disease with parenchymal and nonparenchymal cerebral involvement, immunosuppressive and corticosteroid therapy was started, resulting in the remission of the symptoms.     

Conocimiento sobre el diagnóstico y el tratamiento de la alergia a las proteínas de la leche de vaca por un grupo de gastroenterólogos pediatras en Iberolatinoamérica: resultado de la encuesta del Grupo de Trabajo de Alergia Alimentaria de la Sociedad Latinoamericana de Gastroenterología,Hepatología y Nutrición Pediátrica

IntroductionThere are discrepancies in the diagnosis and management of cow's milk protein allergy (CMPA) in Spain and Latin America. The aim of the present study was to find out how Spanish and Latin American pediatric gastroenterologists diagnose and treat CMPA.Material and methodsPediatric gastroenterologists, members of the Sociedad Latinoamericana de Gastroenterología, Hepatología y Nutrición, were invited to fill out a structured survey, the results of which were then compared with the 2012 and 2014 diagnosis and treatment guidelines, respectively.ResultsThe survey results showed that 17% of the participants follow the diagnostic recommendations based on the published consensus and guidelines. To diagnose non-IgE-mediated CMPA, 15% of the participants utilize IgE-specific skin prick tests, 22% use IgE-specific blood tests, and 45% employ oral food challenges. To diagnose IgE-mediated CMPA the percentages for the same diagnostic methods were 57, 83 and 22%, respectively. Once diagnosis is confirmed, 98% of the participants provide dietary recommendations. In children that are not breastfed, 89% of the participants prescribe an initial extensively hydrolyzed formula, 9% an amino acid formula, 1% a soy formula, and 1% a hydrolyzed rice formula. In patients with IgE-mediated CMPA, 34% of the participants carry out an oral challenge once treatment is completed, 39% according to symptom severity, and 27% in relation to IgE-specific testing.ConclusionCMPA management is diverse and there is poor adherence to the clinical practice guidelines.
