Immediate feeding tolerance in patients with mild acute biliary pancreatitis.

ANTECEDENTES: La pancreatitis aguda leve es una inflamación local del páncreas sin complicaciones locales ni falla orgánica. Su manejo consiste en tres elementos básicos: hidratación, analgesia y ayuno. La realimentación se inicia cuando el paciente no tiene dolor y refiere apetito, pero el momento exacto para iniciarla no está previamente documentado. OBJETIVO: Determinar la tolerancia a la alimentación oral inmediata (8 horas posterior al inicio del manejo) en comparación con la alimentación temprana (48 horas) en los pacientes con pancreatitis aguda biliar leve. MÉTODO: Se incluyeron pacientes con pancreatitis aguda biliar leve y se aleatorizaron en dos grupos: A) alimentación temprana a las 48 horas (30 pacientes) y B) alimentación inmediata a las 8 horas de inicio del manejo (29 pacientes). Fueron evaluados por un tercer observador ciego (no involucrado en el estudio) para documentar síntomas como náusea, vómito, reactivación del dolor abdominal, síndrome de respuesta inflamatoria sistémica, tolerancia alimentaria y estancia hospitalaria. RESULTADOS: No se encontraron diferencias significativas entre los grupos en cuanto a datos clínicos y bioquímicos. La estancia hospitalaria disminuyó significativamente en el grupo B (5.4 vs. 7.8 días; p < 0.003). CONCLUSIÓN: La alimentación inmediata en las primeras 8 horas del manejo de los pacientes con pancreatitis aguda biliar leve es bien tolerada y segura, y reduce la estancia hospitalaria. BACKGROUND: Mild acute pancreatitis is defined as pancreatic edema, without organic failure and without local complications. Its management consists in three basic elements: hydration, analgesia and fasting. Start refeeding when the patient haven´t pain and referring hungry, but exact time for this is not previously documented. OBJECTIVE: To determine the tolerance to immediate oral feeding (8 hours after the start of management) compared to early feeding (48 hours) in patients with mild acute biliary pancreatitis. METHOD: Included all patient with mild acute biliary pancreatitis, and they were randomized in to two groups: A) early oral feeding (n = 30) and B) immediate oral feeding (n = 29). They were evaluated by a third blind observer (not involved in the study) for documented symptoms like nausea, vomiting, reactivation of abdominal pain, systemic inflammatory response syndrome, food tolerance and hospital stay. RESULTS: There were no significant differences between both groups in the clinical data or in the biochemical studies. The hospital stay was significantly less in the group B (5.4 vs. 7.8 days; p < 0.003). CONCLUSION: Immediate oral feeding is well tolerated and secure in patients with mild acute biliary pancreatitis.

Therapeutic Use of Silver Nanoparticles in the Prevention and Arrest of Dental Caries.

Dental caries is one of the major diseases of the oral cavity affecting humans worldwide. Different alternatives have been used for its control, but its incidence and prevalence are still high. On the other hand, silver has been used for centuries due to its antimicrobial properties. With advances in nanotechnology, the use and research in nanomaterials has increased, recently, and silver nanoparticles have become an essential part of the dental practice, giving materials physical and chemical improvements in their properties, used for their antibacterial capacity preventing and arresting dental caries. The objective of this review was to examine the use of silver nanoparticles, in the treatment of dental caries in the remineralization of teeth hard tissues, as well as the antimicrobial potential, cytotoxicity, and long-term effectiveness.

Epidemiology of Bordetella pertussis in San Luis Potosí, Mexico.

We analyzed data from 147 patients with suspected pertussis in San Luis Potosí, Mexico. Bordetella pertussis was detected by real-time polymerase chain reaction in 59 (40.1%) cases. The incidence of B. pertussis infection was 2.3 per 100,000 population. There were 6 deaths among the study patients. We conclude that the impact of pertussis in our state is significantly higher than previously estimated.
