Perspectives of San Juan healthcare practitioners on the detection deficit in oral premalignant and early cancers in Puerto Rico: a qualitative research study

<p>Abstract</p> <p>Background</p> <p>In Puerto Rico, relative to the United States, a disparity exists in detecting oral precancers and early cancers. To identify factors leading to the deficit in early detection, we obtained the perspectives of San Juan healthcare practitioners whose practice could be involved in the detection of such oral lesions.</p> <p>Methods</p> <p>Key informant (KI) interviews were conducted with ten clinicians practicing in or around San Juan, Puerto Rico. We then triangulated our KI interview findings with other data sources, including recent literature on oral cancer detection from various geographic areas, current curricula at the University of Puerto Rico Schools of Medicine and Dental Medicine, as well as local health insurance regulations.</p> <p>Results</p> <p>Key informant-identified factors that likely contribute to the detection deficit include: many practitioners are deficient in knowledge regarding oral cancer and precancer; oral cancer screening examinations are limited regarding which patients receive them and the elements included. In Puerto Rico, specialists generally perform oral biopsies, and patient referral can be delayed by various factors, including government-subsidized health insurance, often referred to as Reforma. Reforma-based issues include often inadequate clinician knowledge regarding Reforma requirements/provisions, diagnostic delays related to Reforma bureaucracy, and among primary physicians, a perceived financial disincentive in referring Reforma patients.</p> <p>Conclusions</p> <p>Addressing these issues may be useful in reducing the deficit in detecting oral precancers and early oral cancer in Puerto Rico.</p

A survey of cariology education in U.S. dental hygiene programs: The need for a core curriculum framework

ObjectiveDental hygienists play a key role in dental caries prevention and management. As the evidence of dental caries risk, prevention, and management becomes more complex, it is essential that dental hygiene (DH) programs have a strong cariology curriculum. This project aimed to assess current cariology content in U.S. DH programs, how content is taught, and interest in development/implementation of a common/core cariology curriculum framework.MethodsDirectors of 336 U.S. DH programs were invited to participate in a voluntary online survey using Qualtrics. The survey consisted of 41 items including demographics, details about the program’s cariology content, and how it was delivered, and items related to a core cariology curriculum.ResultsThe overall response rate used for analyses was 27.3%. Some findings include: 61.6% stated their program had a defined cariology curriculum, 35.2% did not have an individual cariology course, 61.5% had preclinical hands‐on experiences in cariology, 79.7% are teaching management strategies related to salivary gland hypofunction, 68.3% are teaching use of silver diamine fluoride (SDF), and 64.2% felt cariology was adequately being taught. Only 17.7% are teaching the International Caries Detection and Assessment System (ICDAS) system. 87.3% indicated support for developing a core curriculum framework for teaching cariology in DH programs.ConclusionsThis study indicated that, although DH programs reported that cariology concepts are being taught both didactically and clinically, discrepancies between concepts taught and the literature exist. Therefore, there is a need to create a more standardized curriculum framework for all U.S. DH programs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/163812/1/jdd12348.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/163812/2/jdd12348_am.pd

Meteorological and dust aerosol conditions over the western Saharan region observed at Fennec Supersite-2 during the intensive observation period in June 2011

The climate of the Sahara is relatively poorly observed and understood, leading to errors in forecast model simulations. We describe observations from the Fennec Supersite-2 (SS2) at Zouerate, Mauritania during the June 2011 Fennec Intensive Observation Period. These provide an improved basis for understanding and evaluating processes, models, and remote sensing. Conditions during June 2011 show a marked distinction between: (i) a "Maritime phase" during the early part of the month when the western sector of the Sahara experienced cool northwesterly maritime flow throughout the lower troposphere with shallow daytime boundary layers, very little dust uplift/transport or cloud cover. (ii) A subsequent "heat low" phase which coincided with a marked and rapid westward shift in the Saharan heat low towards its mid-summer climatological position and advection of a deep hot, dusty air layer from the central Sahara (the "Saharan residual layer"). This transition affected the entire western-central Sahara. Dust advected over SS2 was primarily from episodic low-level jet (LLJ)-generated emission in the northeasterly flow around surface troughs. Unlike Fennec SS1, SS2 does not often experience cold pools from moist convection and associated dust emissions. The diurnal evolution at SS2 is strongly influenced by the Atlantic inflow (AI), a northwesterly flow of shallow, cool and moist air propagating overnight from coastal West Africa to reach SS2 in the early hours. The AI cools and moistens the western Saharan and weakens the nocturnal LLJ, limiting its dust-raising potential. We quantify the ventilation and moistening of the western flank of the Sahara by (i) the large-scale flow and (ii) the regular nocturnal AI and LLJ mesoscale processes. Key Points First detailed observations from western Sahara sector Intraseasonal shift in Saharan heat low drives meteorological/aerosol conditions Atlantic Inflow interaction with low level jet

Características clínico-epidemiológicas no carcinoma espinocelular de boca e orofaringe Clinic and epidemiologic characteristics in the with squamous cell carcinoma of the mouth and oropharynx

O câncer de boca e orofaringe é de comportamento agressivo e, no Brasil, a incidência é considerada uma das mais altas do mundo, sendo o mais comum da região de cabeça e pescoço. OBJETIVO: O objetivo deste trabalho é analisar os aspectos clínico-epidemiológicos dos pacientes e a evolução da doença. FORMA DE ESTUDO: Clínico retrospectivo. CASUÍSTICA E MÉTODO: Foram arrolados 43 casos de carcinoma espinocelular (CEC) de boca e 25 de orofaringe do Serviço de Cirurgia de Cabeça e Pescoço da Santa Casa de Misericórdia de Santos e do Hospital Ana Costa entre os anos de 1997 a 2000. Informações sobre idade, sexo, profissão, raça, hábitos de tabagismo e etilismo, uso de prótese dentária, origem do encaminhamento do paciente ao tratamento, localização da lesão, estadiamento clínico, grau de diferenciação histológica, tratamento, sobrevida e presença de segundo tumor primário foram analisados estatisticamente pelo Teste Exato de Fischer. RESULTADOS: Dos pacientes com CEC em boca, a relação de incidência masculino-feminino foi de 3,35:1, a idade variou de 46 a 91 anos (mediana de 62), 90,7% eram caucasianos, 81% foram referenciados por profissionais médicos, 76,8% eram tabagistas, 74% etilistas, 79% não utilizavam prótese dentária. O sítio mais acometido foi a língua (51,1%), 53% apresentaram-se nos estádios III e IV, 72,1% eram de grau histológico II, 53% foram tratados por cirurgia e 47% por cirurgia e radioterapia adjuvante e 9,3% apresentaram segundo tumor primário. Para a orofaringe, a relação masculino-feminino foi de 11,5:1, com idade entre 40 e 81 anos (mediana de 58), 92% eram caucasianos, 92% foram encaminhados por médicos, 84% eram tabagistas, 80% etilistas, 52% não utilizavam prótese, as tonsilas palatinas foram o sítio mais acometido (76%), 96% estavam em estádios III e IV, 84% eram de grau II, 80% foram tratados por cirurgia associada a radioterapia, 16% a cirurgia para resgate de falha após radioterapia e 4% a cirurgia exclusiva e 8% tiveram segundo primário. Não houve relação estatisticamente significativa entre o estadiamento e os hábitos de tabagismo, etilismo e uso de prótese. Tais hábitos, a faixa etária e o grau histológico não tiveram relação significativa com o sítio do tumor. Estavam vivos e livres de doença 69,7% dos pacientes com tumor de boca e 22% de orofaringe. CONCLUSÃO: O médico ou dentista que dá o atendimento inicial é fundamental no reconhecimento das lesões, para que se possa estabelecer o diagnóstico precoce.<br>Cancer of the oral cavity and oropharynx is aggressive. It is one of the commonest cancers in Brazil and may be considered as the commonest in the head and neck. AIM: The objective of this paper is to evaluate clinical and epidemiological factors and the outcome. STUDY DESIGN: Clinical retrospective. MATERIAL AND METHODS: In a descriptive retrospective study, the charts of 43 cases of oral and 25 of oropharyngeal squamous cell carcinoma (SCC) in the period 1997-2000 have been reviewed from the Departments of Head and Neck Surgery of Santa Casa de Misericórdia de Santos and Hospital Ana Costa. This was analyzed with emphasis on age, gender, profession, ethnic aspects, tobacco and alcohol use, dental prosthesis, referement origin, site of the lesion, clinical staging, histologic grade, treatment methods, survival and second cancer presence in the study group. The data were analysed by Exact Test of Fischer. RESULTS: In the oral cavity cancer patients, a male female ratio of 3.35:1 was observed, the median age was 62 years (ranging 46 to 91 years), 90.7% were Caucasian, 81% were referred from medical professionals, tobacco use was identified in 76.8%, alcohol intake in 74%, 79% were not dental prosthesis users, tongue was the commonest site identified (51.1%), 53% were staged as III and IV clinical stages, 72.1% were moderately differentiated SCC, combined modality of treatment (surgery and adjuvant radiation therapy) was employed in 47% and 9.3% presented a second primary tumor. For the oropharynx, the male female ratio was 11.5:1, the median age was 58 years (ranging 40 to 81 years), 92% were Caucasian, 92% were referred from medical professionals, exposure to tobacco and alcohol was respectively noted in 84% and 80%, 52% did not use dental prosthesis, the tonsils were the commonest site (76%), 96% were staged as III and IV, 84% had moderately differentiated SCC, 75% underwent combined treatment (surgery and adjuvant radiation therapy) and 8% presented a second tumor elsewhere. There was not significant relationship between the clinical staging and tobacco, alcohol and dental prosthesis exposure. These factors, the age and the histologic grade had no relationship with the tumor site. For the oral cavity, 69,7% were alive with no evidence of disease and for the oropharynx, 22% were under this condition. CONCLUSION: The professional who performs the first evaluation is important in recognizing the lesions in order to achieve early detection
