RESUMO
OBJECTIVE: To explore the therapeutic effect and safety of target-dose metoprolol in treating chronic heart failure (CHF) patients complicated with diabetes mellitus (DM). Method s : One hundred and fifty-four elderly patients were randomly divided into an observation group and a control group (n=77), which were treated with target-dose metoprolol and conventional therapy, and routinely treated respectively. The New York Heart Association (NYHA) classification, left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), 6-min walking distance and medication safety of the two groups were compared. RESULTS: Compared with the results before treatment, the NYHA classification, LVESD, LVEDD, LVEF and 6-minutes walking distance of both groups were significantly improved (P<0.05), with significantly better results in the observation group than those in the control group after treatment (P<0.05). In the 6 months of follow-up, the incidence of cardiac events in the observation group (3.90%) was significantly lower than that of the control group (14.29%) (P<0.05). The levels of average fasting blood sugar and glycosylated hemoglobin in the groups showed no significant differences (P>0.05). CONCLUSION: Treating CHF patients complicated with DM with target-dose metoprolol can obviously boost the cardiac function and exercise tolerance, leading to satisfactory clinical therapeutic effect, high security and moderate tolerance.
RESUMO
With the ongoing economic development, lifestyle changes and an aging population, diabetes mellitus has be come one of the most prevalent chronic diseases in the world. Rhino-orbito-cerebral (ROC) mucormycosis is a rare, acute and angioinvasive fungal infection that can be fatal. Mucormycosis occurs exclusively in immunocompromised patients with diabetes mellitus and other types of immunodeficiency and has three subtypes: Rhino-maxillary, rhino-orbital and ROC mucormycosis. The present study reported on a case of ROC mucormycosis in a patient with diabetic ketoacidosis. In the present case, the pathogen afflicted all of the above organs, including the left eye, nasal cavity, hard palate and cerebrum.
RESUMO
Hepatic infarction rarely occurs due to the double supply of arterial and portal inflow. A 53-year-old man with diabetes mellitus developed multiple hepatic infarctions after an episode of fever and diarrhea. The infarction was documented by pathology after partial liver resection. Several causes of hepatic infarction may present in this patient: dehydration and hypotension caused by fever and diarrhea, type 2 diabetes and administration of glibenclamide, diabetic ketoacidosis and widespread atherosclerosis. We suggest that diabetic patient with elevated liver enzyme should be considered the possibility of hepatic infarction.
