Factors Related to Noncompliance in Screening and Tracking Mild Cognitive Impairment Patients in a Single Community

OBJECTIVE: We assessed the cumulative conversion rates (CCR) from minor cognitive impairment (MCI) to dementia among individuals who failed to participate in annual screening for dementia. Additionally, we analyzed the reasons for failing to receive follow-up screening in order to develop better strategies for improving follow-up screening rates. METHODS: We contacted MCI patients who had not visited the Dongdaemun-gu Center for Dementia for annual screening during the year following their registration. We compared the CCR from MCI to dementia in the following two groups: subjects registered as having MCI in the Dongdaemun-gu Center for Dementia database and subjects who failed to revisit the center, but who participated in a screening test for dementia after being contacted. The latter participants completed a questionnaire asking reasons for not previously visiting for follow-up screening. RESULTS: The final diagnoses of the 188 subjects who revisited the center only after contact were 19.1% normal, 64.9% MCI and 16.0% dementia. The final diagnoses of the 449 subjects in the Dongdaemun-gu Center for Dementia database were 25.6% normal, 46.1% MCI and 28.3% dementia. The CCR of the revisit-after-contact group was much lower than anticipated. The leading cause for noncompliance was “no need for tests” at 28.2%, followed by “other reasons” at 23.9%, and “I forgot the appointment date” at 19.7%. CONCLUSION: Considering the low dementia detection rate of the group who revisited only after contact and the reasons they gave for noncompliance, there appears to be a need for ongoing outreach and education regarding the course and prognosis of MCI.

A Case of Arteriovenous Malformation of the Parotid Gland / 대한이비인후과학회지

Arteriovenous malformation is a part of the spectrum of vascular malformations that involve shunting of blood from the arterial vessel directly into the venous system. The most frequent locations, in order of incidence, are the extremities, the lungs, and the head and neck. However, arteriovenous malformation of the parotid gland is rare, The "turkey wattle" sign describes the enlargement of a facial mass in dependency of the head, and when present, it is pathognomonic of hemangioma or vascular malformation. The treatment of choice is to complete removal of the mass by surgery to stop their progress. We report a recent encounter with a case of arteriovenous malformation of the parotid gland in a 43-year-old female patient. This disorder was successfully removed by total parotidectomy with the preservation of the facial nerve.

A Case of Intraparotid Facial Nerve Neurofibroma / 대한이비인후과학회지

Neurogenic neoplasms of the facial nerve are uncommon. These neoplasms are usually classified into two types: schwannoma and neurofibroma. Although intraparotid facial nerve schwannomas have been documented sporadically throughout the medical literature, neurofibromas from intraparotid facial nerve are extremely rare. Neurogenic neoplasms of the intraparotid facial nerve are usually diagnosed intraoperatively by tissue biopsy. The management of neurogenic tumors associated with normal facial function is a particularly difficult problem. These benign tumors of neurogenic origin should be considered in the differential diagnosis of parotid masses. This is a case report of a solitary neurofibroma involving the main trunk of the facial nerve in the parotid gland.
