Introduction. The posterior glenohumeral dislocation (PGD) is misdiagnosed frequently. This is associated with high-energy trauma, sports, seizures and electrocutions. The diagnosis is often omitted because of in most of the cases a striking deformity is not seen in the injured joint. Also, initial x-ray images are very similar to those from an uninjured shoulder. A 30-year-old man was admitted to the emergency room after falling onto his left shoulder, no joint deformity was observed. Anteroposterior and transthoracic X-ray showed PGD. Closed reduction was performed under general anesthesia. At 4-year follow-up, the patient has no sequels and preserves joint mobility without pain.

Objetive: To describe a pediatric case with initial diagnosis of lymph node tuberculosis (TB) that became multidrug resistant miliar and meningeal tuberculosis (TB-MDR) due to treatment dropout twice. Case report: a 4-year-old boy with initial diagnosis of lymph node tuberculosis who had two episodes of dropout from the sensitive scheme treatment. Three months later, there was evidence of bilateral involvement suggestive of miliary TB. During hospitalization, he developed meningeal tuberculosis and hydrocephalus. Due to the history of treatment dropout, a sensitivity of gastric aspirate study was requested, identifying it as multidrug-resistant TB. He started the EZLfxKmEtoCs treatment scheme and complications management, achieving improvement. Conclusions: Treatment dropout is one of the main causes of drug resistance in tuberculosis and its complications. It is necessary to reinforce t...

Objetivo: Determinar el efecto de la miel de abeja sobre úlceras gástricas inducidas por piroxicam en ratas Holtzman. Material y método: Se trabajó con 48 ratas hembra Holtzman de ocho semanas de edad con pesos entre 100 y 200 g, divididas en 6 grupos, con las siguientes intervenciones: Grupo A: agua; Grupo B: piroxicam (30 mg/kg); Grupo C: omeprazol (5 mg/kg) y piroxicam (30 mg/kg); Grupo D: miel (2,5 g/kg) y piroxicam (30 mg/kg); Grupo E: miel (5 g/kg) y piroxicam (30 mg/kg); Grupo F: miel (7,5 g/kg) y piroxicam (30 mg/kg). Luego de las intervenciones se realizaron estudios macroscópicos de las lesiones de la mucosa gástrica mediante el paquete Scion Image® y microscópicos, por estudio histológico. Resultados: El estudio macroscópico determinó que la miel a dosis de 5 g/kg y 7,5 g/kg se asoció a úlceras gástricas significativamente menores que el piroxicam (p=0,016 y p=0,...
