To establish whether there is an association between obesity and diabetic retinopathy in adult patients with type 2 diabetes mellitus. METHODOLOGY: An analytical, retrospective and transversal study, in which 102 patient records were reviewed that met inclusion and exclusion criteria. RESULTS: We studied 102 patients (34 cases and 68 controls), in the group of cases, 10 patients with diabetic retinopathy were obese (29%) and 32 patients without diabetic retinopathy were obese (47 %) (Table 1). There were no significant differences between cases and controls regarding the age, the sex and the time of diagnosis. The OR of obese diabetic retinopathy was 0.37 (95% confidence interval [CI], 0.15-0.89, p = 0.0266). The chi-square statistic was 5.0683, with p being 0.024 for a p level of significance <0.05. CONCLUSION: From the present study, we concluded that, the probability of developing dia...

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.

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,...
