Diagnostic implications of oral intravascular papillary endothelial hyperplasia

This study examined the clinical, histological, and immunohistochemical features as well as the differential diagnoses of oral intravascular papillary endothelial hyperplasia (IPEH) to aid clinicians and pathologists in its diagnosis. Clinical features of five oral IPEH cases were obtained from medical records, and all histopathological diagnoses were reviewed. Immunohistochemical reactions, including anti-CD-34, laminin, vimentin, estrogen receptor alpha, and Ki-67, were assessed. Microscopically, a reactive proliferation of vascular cells composed of small papillary structures with hypocellular and hyalinized cores arising in an organized thrombus was seen. CD-34, vimentin, and laminin staining were strongly positive, while estrogen receptor alpha was negative in all cases. A low percentage of cells were positive for Ki-67 in four of five lesions, but one case was strongly positive. A diagnosis of angiosarcoma was investigated and rejected. IPEH presents specific microscopic characteristics that along with clinical data lead to an accurate diagnosis. The general dentist, the first to participate in the diagnostic process, must share the responsibility for diagnosis with the pathologist, and they must work together to determine the correct diagnosis and management. Oral lesions of IPEH are uncommon. Their main significance is that they show a microscopic resemblance to angiosarcoma. Thus, clinicians should have more information regarding this benign entity. Finally, we suggest that in recurrent cases exhibiting strong immunolabeling of proliferative markers the possibility of angiosarcoma should be investigated.

Telehealth in audiology: The need and potential to reach underserved communities

Permanent hearing loss is a leading global health care burden, with 1 in 10 people affected to a mild or greater degree. A shortage of trained healthcare professionals and associated infrastructure and resource limitations mean that hearing health services are unavailable to the majority of the world population. Utilizing information and communication technology in hearing health care, or tele-audiology, combined with automation offer unique opportunities for improved clinical care, widespread access to services, and more cost-effective and sustainable hearing health care. Tele-audiology demonstrates significant potential in areas such as education and training of hearing health care professionals, paraprofessionals, parents, and adults with hearing disorders; screening for auditory disorders; diagnosis of hearing loss; and intervention services. Global connectivity is rapidly growing with increasingly widespread distribution into underserved communities where audiological services may be facilitated through telehealth models. Although many questions related to aspects such as quality control, licensure, jurisdictional responsibility, certification and reimbursement still need to be addressed; no alternative strategy can currently offer the same potential reach for impacting the global burden of hearing loss in the near and foreseeable future.
