Frecuencia de portadores de Staphylococcus aureus resistentes a meticilina (SARM) en cavidades nasales en el personal de discentes de la Escuela Militar de Medicina / Frequency of methicillin-resistant Staphylococcus aureus (MRSA) in nasal cavities in the personnel of the Escuela Militar de Medicina

Resumen Antecedentes: Las infecciones nosocomiales ocasionadas por cepas de Staphylococcus aureus resistentes a meticilina (SARM) son un problema de salud importante en todo el mundo. Este microorganismo produce una gran variedad de infecciones incluyendo osteomielitis, endocarditis invasora, artritis séptica y septicemia. S. aureus se encuentra habitualmente en piel y cavidad nasal, se disemina fácilmente a través de fómites, contacto piel-piel o contacto con fluidos nasales. Los discentes de la EMM están en contacto continuo con pacientes del Hospital Central Militar y pueden adquirir o diseminar este tipo de microorganismos. De aquí la importancia de la medicina preventiva, con el fin de valorar la frecuencia de este microorganismo y utilizar medidas sanitarias que puedan evitar su diseminación. Objetivo: Determinar la frecuencia de portadores de Staphylococcus aureus resistentes a meticilina (SARM) en discentes de la Escuela Militar de Medicina. Metodología: Muestras de mucosa de la cavidad nasal de discentes de la Escuela Militar de Medicina del 2do a 5to año, fueron cultivadas en agar sangre y agar sal-manitol, se seleccionaron cepas con morfología colonial y microscópica correspondiente S. aureus, se realizó pruebas de catalasa y coagulasa, cepas positivas a S. aureus fueron sometidas a antibiograma utilizando sensidiscos de oxacilina y la resistencia fue determinada a partir del diámetro en el halo de inhibición. Los discentes portadores recibieron tratamiento erradicador con mupirocina al 5% intranasal por 7 días y se tomaron nuevamente muestras para determinar la persistencia de S. aureus en la cavidad nasal. Resultados: De los 110 discentes de la Escuela Militar de Medicina a quienes se le tomó muestras 51 pacientes (46.36%) resultaron portadores positivos a S. aureus, el antibiograma con discos de oxacilina mostró una resistencia a meticilina de 12 pacientes correspondiente al 10.9%, mientras que con la terapia antibiótico erradicador con mupirocina al 5% intranasal, la presencia de S. aureus resistente a meticilina disminuyo al 0%. Conclusiones: Se obtuvo un 10.9% de discentes portadores de S. aureus resistente a meticilina, mismo que fue erradicado en su totalidad con mupirocina al 5% intranasal.

Abstract Background: Nosocomial infections caused by strains of methicillin-resistant Staphylococcus aureus (MRSA) are a major health problem throughout the world. This microorganism produces a wide variety of infections including osteomyelitis, invasive endocarditis, septic arthritis, and septicemia. S. aureus is usually found in the skin and nasal cavity, it is easily spread through fomites, skin-skin contact or contact with nasal fluids. The students of the EMM are in continuous contact with patients of the Hospital Central Militar and can acquire or disseminate this type of microorganisms. Hence the importance of preventive medicine, in order to assess the frequency of this microorganism and use sanitary measures that can prevent its spread. Objective: To determine the frequency of resistant methicillin-resistant Staphylococcus aureus (MRSA) carriers in students of the Escuela Militar de Medicina. Methodology: Mucosa samples from the nasal cavity of students of the Escuela Militar de Medicina from the 2nd to 5th year, were cultured on blood agar and salt-mannitol agar, strains with corresponding colonial and microscopic morphology were selected S. aureus, tests were performed of catalase and coagulase, positive strains of S. aureus were subjected to antibiogram using oxacillin sensitives and the resistance was determined from the diameter in the inhibition zone. Student carriers received eradicating treatment with intranasal 5% mupirocin for 7 days and samples were taken again to determine the persistence of S. aureus in the nasal cavity. Results: Of the 110 students of the Escuela Militar de Medicina who were sampled 51 patients (46.36%) were positive carriers to S. aureus, the antibiogram with oxacillin discs showed a resistance to methicillin of 12 patients corresponding to 10.9%, while that with antibiotic eradication therapy with 5% intranasal mupirocin, the presence of resistant S. aureus Methicillin decreased to 0%. Conclusions: A 10.9% of students carriers of resistant S. aureus methicillin were obtained, which was eradicated in its entirety with 5% intranasal mupirocin.

Manejo de tejidos blandos en implantes con carga inmediata del sector anterosuperior: reporte de caso clínico / Handling of soft tissues of an immediate loading implant on the upper anterior sector: report of a clinical case

Los implantes dentales se han colocado en sitios de extracción cicatrizados mediante un procedimiento quirúrgico en dos etapas para un periodo de tres a seis meses sin carga. Sin embargo, los pacientes esperan ser rehabilitados lo antes posible, especialmente los pacientes sometidos a restauraciones estéticas en el maxilar anterior. Después de la colocación del implante, la fabricación de la restauración temporal y la carga del implante dentro de las 48 horas se denominan carga inmediata. Esto acorta el tiempo del tratamiento, ya que requiere menos intervenciones quirúrgicas, reduce la pérdida ósea crestal periimplantaria, conduce a la preservación de la morfología de los tejidos blandos y mejora la estética. En este artículo se hablará del caso clínico de un paciente femenino de 44 años de edad que presentaba pérdida del órgano dentario 21. Se realizó valoración periodontal, radiográfica y tomográfica de este órgano dentario, se colocó implante con la utilización de guía quirúrgica y protésica acrílica termocurable, se realizó carga inmediata, el provisional fue conformado con contorno subgingival cóncavo y se toman en cuenta criterios de contorno crítico y subcrítico para el desarrollo ideal del perfil de emergencia. En las citas de valoración se encontraron los tejidos periimplantales estables y la paciente no refirió sintomatología (AU)

Dental implants have been placed in scarred extraction sites by a twostage surgical procedure for a period of three to six months without load. However, patients expect to be rehabilitated as soon as possible, especially patients undergoing esthetic restorations in the anterior maxilla. After implant placement, the fabrication of the temporary restoration and implant loading within 48 hours are called immediate loading. This shortens the time of treatment, beacause it requires fewer surgical interventions, reduces peri-implant crestal bone loss, leads to the preservation of soft tissue morphology and improves aesthetics. In this article we will discuss the clinical case of a 44-year-old female patient who had lost the dental organ 21. Periodontal, radiographic and tomographic assessment of this dental organ was performed, an implant was placed with the use of surgical guide and acrylic prosthesis thermocurable, immediate loading was performed, the provisional was formed with a concave subgingival contour and critical and subcritical contour criteria were taken into account for the ideal development of the emergence profile. In the assessment appointments stable periimplant tissues were found and the patient did not report symptoms (AU)

Utilidad de las biopsias gástricas rutinarias y de la tinción con azul de metileno en el diagnóstico de la metaplasia intestinal en mayores de 40 años / [Utility of routine gastric biopsies and staining with methylene blue in the diagnosis of intestinal metaplasia in patients over 40 years].

OBJECTIVE: To evaluate the diagnostic utility of routine gastric biopsies taken at random versus targeted biopsies with methylene blue staining for the diagnosis of intestinal metaplasia. MATERIAL AND METHODS: We performed a validation study in 376 patients. We performed 2 antral biopsies, 2 gastric body biopsies, 1 biopsy for urease test and additional biopsies if demanded. One hundred and one patients underwent 2 biopsies after methylene blue staining. A total of 1,486 biopsies were analyzed. Frequencies of histological and endoscopic diagnosis and the validation of endoscopic diagnosis of intestinal metaplasia with and without staining against histology, which followed updated Sydney and Vienna criteria, were determined RESULTS: Metaplasia was found in 37.23

ofcases and in 6.38

was incomplete in antrum and body, moderate or severe. The endoscopic diagnosis had: sensitivity 46

. The low sensitivity indicates the need for gastric biopsies. Staining had: sensitivity 95

, with significant difference for staining (P < 0.05). The typical endoscopic appearance of intestinal metaplasia always coincided with staining and histology. Dysplasia was found in 0.53

ofcases, gastric cancer in 1.8

and Helicobacter pylori in 56

. CONCLUSION: Directed biopsy staining is superior to those taken at random for diagnosing metaplasia. Metaplasia was not found when endoscopy was normal and typical endoscopic appearance of metaplasia agreed with staining and histology.

La nutrición en la práctica deportiva: adaptación de la pirßmide nutricional a las características de la dieta del deportista / Nutrition in the sport practice: adaptation of the food guide pyramid to the characteristics of athletes diet

In spite of all the advances in sport nutrition and the importance of an adequate food intake in order to improve sport performance, both recreational and professional athletes forget frequently to include planning an optimum diet and fluid intake in their global strategy for performance. Physiological and metabolic adaptations produced as a consequence of physical exercise lead to the necessity of increasing caloric (in accordance to energy output) and protein (based on the trophic needs of the organism) intake. Likewise, paying major attention to vitamin and mineral intake, specifically B vitamins and zinc and chromium, is required, in order to optimize carbohydrate metabolism, the ultimate limiting factor for sport performance. During the training phase, 60 of calories should come from carbohydrates, protein intake should be 1.2-2 g/kg/day and athletes should follow the recommendations of the food guide pyramid. During the pre-, per- and post-competition phase the healthy aspect of the diet passes to a second level, in order to obtain good sport performance and to guarantee a fast and effective recovery. Again, carbohydrates with a high or medium glycaemic index and water are the nutrients which have to be calculated more thoroughly. In conclusion, athletes have to follow a diet that is adequate to their higher energy output and to their higher metabolic turnover. The food guide pyramid is a graphic expression which facilitates the comprehension and following of a healthy diet. In the present article, the authors introduce the pyramid adapted to the characteristics of sports nutrition, with easy-to-follow practical recommendations regarding the kind and amounts of foodstuffs that should be consumed in order to cover nutrient needs of people who exercise regularly.
