Utility of decellularised urinary bladder extracellular matrix in full mucosalisation of a post-oncological maxillectomy defect.

This report highlights the utility of MatriStem Surgical Matrix Thick UBM™ (rebranded as Gentrix® ACell, Inc), a decellularised urinary bladder extracellular matrix in the reconstruction of a post-oncological maxillectomy defect. In utilising this biological construct to serve as a biological dressing, our patient underwent complete mucosalisation of his surgical site without the development of an oroantral fistula and with adequate maxillary vestibule to allow for definitive oral rehabilitation with a removable partial denture.

A National, Randomized Survey of HIV/AIDS Knowledge and Attitudes Among Psychiatrists in Training.

Given the broad spectrum of medical and psychiatric complications associated with HIV (human immunodeficiency virus) disease, HIV-related education is an important curriculum topic for all physicians. This study examined the HIV-related knowledge and attitudes among psychiatrists in training to evaluate their training needs. A survey instrument was developed containing 15 knowledge items, 15 attitude items, demographic items, and questions concerning how HIV/AIDS (acquired immunodeficiency syndrome) affected residency choice and self-perception of training needs. The questionnaire was mailed to 2,252 psychiatrists in training randomly selected and stratified by American Psychiatric Association district and postgraduate training year. The sample consisted of 825 respondents representing 37% of the initial pool. Knowledge was most lacking in areas dealing with HIV-related neuropsychiatric complications and issues concerning HIV/AIDS and special populations. In general, the respondents expressed positive attitudes about HIV-related issues; however, three items correctly endorsed by fewer than 75% of the sample dealt specifically with the management of neuropsychiatric complications, working with dying patients, and the range of normal sexuality. Targeted HIV-related education is needed for psychiatrists in training and particularly should encompass neuropsychiatric syndromes and issues of special populations.
