In Western populations, tobacco and alcohol use are the major etiologic factors associated with oral cavity cancers. In developing countries of Asia and the South Pacific, however, oral cancer is increasingly associated with the chewing of betel nut. As the population of Asia and the South Pacific immigrates, Head and Neck surgeons in North America are likely to see more patients with oral carcinoma induced by betel nut chewing. Tumor Registry records from 1977-2003 from a tertiary care, referral medical center were reviewed. All patient charts (27) demonstrating betel quid use of greater than 20 years and carcinoma of the upper aerodigestive tract were entered into the study. Five-year disease-free rates by stage were as follows: Stage 1: 100% (2/2); Stage 11: 50% (2/4); Stage III: 36% (4/9): Stage IV: 25% (3/12). Despite the prevalent misperception in the Pacific region that betel nut chewing is a harmless habit, betel nut-induced oral carcinomas are aggressive malignancies requiring aggressive treatment and long-term follow-up.

Four novel arecoline alkaloid atropisomers, arechuines A-D (-), were obtained from the peels of L. Their structures were elucidated by UV, IR, MS and NMR spectra. The absolute configurations of (+)/(-)- were determined by comparing the experimental and calculated ECD spectra.

Often referred to as 'the last unknown', Papua New Guinea's largely unexplored environments across its four distinct regions, the Highlands, New Guinea Islands, Momase, and Southern, exhibit remarkable diversity. Understanding this diversity is significant in contextualising the risk factors associated with developing non-communicable diseases. This review aims to map and summarise the literature to provide region-specific prevalence data for risk factors and non-communicable diseases.

The transmission cycle is complex, involving multiple vector and host species, but there are significant gaps in ecological knowledge. Empirical data on pathogen-vector-host interactions and incrimination have not been updated since the last century, despite significant local changes in land use and the expansion of KFD to new areas.

Betel quid contains two major ingredients; Areca catechu and Piper betel, often consumed with slaked lime, tobacco, certain flavouring agents, colouring agents, herbs, and spices according to personal preferences. The areca nut alkaloids (arecoline, arecaidine, guvacine, and guvacoline), and tobacco alkaloids (nicotine, nornicotine) undergo nitrosation during chewing in the oral cavity with the presence of nitrite and thiocyanate and endogenously. Among the nitrosation products generated areca nut-derived nitrosamine (ADNA): 3-(methylnitrosamino) Propionitrile (MNPN) and the two tobacco-specific nitrosamines (TSNAs); N'-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone) (NNK) are considered Group 1 human carcinogens.
