A Giant Pseudo-Aneurysm on the Anastomosis Site for a Redo Bentall Operation due to Behçet Disease Treated by Thoracic Endovascular Aortic Aneurysm Repair with a Custom-Made Stent Graft.

A 34-year-old man who had undergone aortic valve replacement 8 years ago underwent an additional Bentall operation due to mechanical valve dehiscence 2 years later. Subsequently, he was diagnosed with Behçet disease and Batter syndrome. A week after being hospitalized again due to chest pain and dyspnea, a large pseudo-aneurysm was detected on computed tomography. Because of the excessively large size of the pseudo-aneurysm, surgical treatment seemed very risky. Therefore, we planned to perform thoracic endovascular aortic repair (TEVAR) and treated him successfully. However, the patient experienced recurrence of the same symptoms 4 months later, and was found to have type IV endoleak. He received a TEVAR procedure again, and it was successful.

Effect of Psychotropic Drugs on Development of Diabetes Mellitus in Patients With Alzheimer's Disease.

We aimed to examine risk of diabetes mellitus (DM) among older adults with Alzheimer's disease receiving 3 types of psychotropic drugs, that is, antipsychotics, antidepressants, and sedative anxiolytics. We retrospectively analyzed data from a hospital-based Clinical Research Center for Dementia of South Korea (CREDOS) study conducted between January 1, 2008 and December 31, 2012. Participants (n = 3042) with Alzheimer's disease were aged 65 or older and had no preexisting history of DM. Development of DM was identified using claims for initiating at least 1 prescription of antidiabetic medications or a diagnosis of DM during the follow-up period. Cox proportional hazards regression was used to demonstrate the Hazard ratio of DM in use of each psychotropic drug. Among the 3042 participants, 426 patients (14.0%) developed DM, representing an incidence rate of 5.2/100 person-years during an average 2.9 years of follow-up period. Among the 3 types of psychotropic drugs, antipsychotic users had a significantly higher risk of DM (hazard ratio = 1.74, 95% confidence interval = 1.10, 2.76) than nonusers, after adjusting covariates. Antidepressants and sedative anxiolytics did not achieve statistical significance. These results suggested that the diabetes risk was elevated in Alzheimer patients on antipsychotic treatment. Therefore, patients with Alzheimer's disease receiving antipsychotic treatment should be carefully monitored for the development of DM.

Severity of White Matter Hyperintensities and Length of Hospital Stay in Patients with Cognitive Impairment: A CREDOS (Clinical Research Center for Dementia of South Korea) Study.

BACKGROUND & OBJECTIVE: White matter hyperintensities (WMHs) contribute to aggravation of dementia or geriatric syndrome, thereby resulting in functional impairment. However, evidence of direct association between WMHs and medical resource utilization indicated by length of hospital stay (LOS) is scarce in patients with cognitive impairment. This study aimed to examine the relationship between the severity of WMHs and LOS in patients with cognitive impairment. METHODS: 4,253 older adults with cognitive impairment were enrolled in this study. We defined LOS as the total sum of days from January 1, 2008 to December 31, 2012. The severity of periventricular (PVWMHs), deep (DWMHs), and overall white matter hyperintensities (Overall WMHs) was evaluated by a visual rating scale. We conducted multinomial logistic regression to demonstrate the relationship between LOS and severity of PVWHMs, DWHMs, and Overall WMHs, respectively. RESULTS: The median LOS was 20 days. Severe PVWMHs had a higher likelihood of longer LOS (Q3: odd ratio/OR = 1.32, 95% confidence interval/CI = 1.06-1.64; Q4: OR = 1.33, 95% CI = 1.07-1.65; Q5: OR = 1.55, 95% CI = 1.26-1.91). As for DWMHs, moderate DWMHs were related to longer LOS (Q4: OR = 1.33, 95% CI = 1.03-1.71; Q5: OR = 1.63, 95% CI = 1.26-2.11). Finally, severity of overall WMHs was independently associated with LOS, which was similar to the results of DWMHs. CONCLUSION: These findings would advocate for prevention of WMHs to stave off excess medical resource utilization in patients with cognitive impairment.
