COVID-19, Home Training for Patients with Diabetes Mellitus / 임상당뇨병

Due to the coronavirus disease 2019 (COVID-19) pandemic, people's physical activity has declined by 35% because their time spent at home has increased. Decreased physical activity can increase both the number of people with type 2 diabetes annually by more than 11.1 million and the number of deaths by more than 1.7 million. Thus, exercise is important during the COVID-19 pandemic, especially in relation to diabetes. If a person with the COVID-19 virus lacks exercise, the risk of hospitalization is increased by 2.2 times and the risk of death by 2.5 times. In the context of COVID-19, the purpose of home training for patients with diabetes mellitus is to reduce body fat percentage, increase muscle function and mass, and improve insulin resistance. The recommended home training program is a circuit-based exercise regime that combines aerobic exercise and strength exercise. In addition, muscle stretching exercises are recommended for home training programs to increase muscle function.

e Prevalence of Psychotic Experiences in the Korean General Population and its Association with Psychiatric Disorders / 생물치료정신의학

Objectives@#：The aim of this study was to investigate the lifetime prevalence of psychotic experiences (PEs) and the association of PEs with a range of psychiatric disorders in the Korean general population. @*Methods@#：Multi-stage cluster sampling was adopted in this study. Interviews were conducted face-to-face with 18-year-old and older people living in the community from June to November 2016. Korean version of Composite International Diagnostic Interview (K-CIDI) was applied to assess the prevalence of psychiatric disorders. Psychotic experiences were assessed with 21 items (15 items for hallucinations and 6 items for delusions) in the CIDI psychosis module. @*Results@#：Mean lifetime prevalence (standard error) of ever having a PEs was 3.3% (0.3) with 2.2% (0.2) of hallucinatory experiences and 1.7% (0.2) of delusional experiences. The lifetime prevalence of PEs was higher in young people and in persons with unemployment or part-time-job. PEs were associated with an increase in the lifetime prevalence of anxiety disorders [Adjusted odd ratio (AOR)=6.3 ; p<0.001], mood disorders (AOR=4.9 ; p<0.001), alcohol use disorders (AOR=2.4 ; p<0.001), and nicotine use disorders (AOR=2.4 ; p<0.001) after controlling for sociodemographic variables. @*Conclusion@#：PEs are related to various non-psychotic disorders as well as psychotic disorders. Clinicians should pay more attention to the mental health of individuals with PEs.

A Rare Case of Subarachnoid Hemorrhage caused by Ruptured Venous Varix Due to Dural Arteriovenous Fistula at the Foramen Magnum Fed Solely by the Ascending Pharyngeal Artery

Dural arteriovenous fistula (D-AVF) at the foramen magnum is an extremely rare disease entity. It produces venous hypertension, and can lead to progressive cervical myelopathy thereafter. On the other hand, the venous hypertension may lead to formation of a venous varix, and it can rarely result in an abrupt onset of subarachnoid hemorrhage (SAH) when the venous varix is ruptured. The diagnosis of D-AVF at the foramen magnum as a cause of SAH may be difficult due to its low incidence. Furthermore, when the D-AVF is fed solely by the ascending pharyngeal artery (APA), it may be missed if the external carotid angiography is not performed. The outcome could be fatal if the fistula is unrecognized. Herein, we report on a rare case of SAH caused by ruptured venous varix due to D-AVF at the foramen magnum fed solely by the APA. A review of relevant literatures is provided, and the treatment modalities and outcomes are also discussed.

Predictable Values of Decompressive Craniectomy in Patients with Acute Subdural Hematoma: Comparison between Decompressive Craniectomy after Craniotomy Group and Craniotomy Only Group / 대한신경손상학회지

OBJECTIVE: Patients with traumatic acute subdural hematoma (ASDH) often require surgical treatment. Among patients who primarily underwent craniotomy for the removal of hematoma, some consequently developed aggressive intracranial hypertension and brain edema, and required secondary decompressive craniectomy (DC). To avoid reoperation, we investigated factors which predict the requirement of DC by comparing groups of ASDH patients who did and did not require DC after craniotomy. METHODS: The 129 patients with ASDH who underwent craniotomy from September 2007 to September 2017 were reviewed. Among these patients, 19 patients who needed additional DC (group A) and 105 patients who underwent primary craniotomy only without reoperation (group B) were evaluated. A total of 17 preoperative and intraoperative factors were analyzed and compared statistically. Univariate and multivariate analyses were used to compare these factors. RESULTS: Five factors showed significant differences between the two groups. They were the length of midline shifting to maximal subdural hematoma thickness ratio (magnetization transfer [MT] ratio) greater than 1 (p 1, IVH, and TICH on preoperative brain computed tomography images, intraoperative signs of intracranial hypertension, brain edema, and bleeding tendency were identified as factors indicating that DC would be required. The necessity for preemptive DC must be carefully considered in patients with such risk factors.
