Tooth loss in treated periodontitis patients responsible for their supportive care arrangements

Aim: To identify risk indicators associated with tooth loss and periodontitis in treated patients responsible for arranging supportive periodontal care (SPC). Materials and Methods: Ninety-seven Chinese subjects (34-77 years) who showed favourable responses to periodontal therapy provided in a teaching hospital 5-12 years previously were recalled. They were advised to seek regular SPC on discharge. Background information, general health status, smoking, oral hygiene habits, follow-up dental care, tooth loss, and periodontal parameters were investigated. Multiple regression analysis was performed. Results: Two hundred and fifty-six teeth had been lost, 195 because of self-reported periodontal reasons. Up to 26.8% sites were with pockets ≥6 mm. Positive correlations were found between total/periodontal tooth loss and (i) smoking pack-years, (ii) time spent on oral hygiene, (iii) years since therapy's conclusion, (iv) age, and negative correlations with (v) inter-dental brush use, and (vi) education levels. Tooth loss by arch was correlated with wearing of removable partial denture in that arch. Percentage sites with pockets ≥6 mm were significantly negatively correlated with percentage sites without bleeding on probing. Conclusions: Smokers, more elderly patients, removable partial denture wearers, and patients with lower education levels or not using inter-dental brushes ought to be targeted for clinic-based SPC. © Blackwell Munksgaard, 2006.postprin

Predictors of treatment outcome in patients treated with radical chemoradiotherapy for stage III Non-small Cell Lung Cancer

Proffered SessionBACKGROUND: Chemoradiation has been well established as standard treatment for stage III non-small cell lung cancer (NSCLC). Previous studies have shown that the tumour size as well as its metabolic activity predict treatment outcome after definitive treatment for early-stage disease. We would like to investigate if there are any clinical and metabolic predictors of treatment outcome for stage III NSCLC after chemoradiation. PATIENTS AND METHODS: 56 consecutive patients (46 males and 10 females) treated with radical concurrent chemoradiation for their stage IIIA (n=21) and IIIB (n=35) (AJCC 7th edition) unresectable non-small cell lung cancer between July 2006 to February 2012 were retrospectively reviewed. 42 patients had positron emission tomography with integrated computed tomography (PET-CT) scan performed at diagnosis. Of which 14 patients also had PET-CT scan after induction chemotherapy and before concurrent chemoradiation. All received concurrent chemoradiation +/- induction ...postprin

Comparison of post-treatment plasma EBV DNA with nasopharyngeal biopsy in patients after radical (chemo) radiotherapy for non-metatatic nasopharyngeal cancer

This journal suppl. entitled: Proceedings of the American Society for Radiation Oncology 56th Annual Meeting, ASTRO's 56th Annual Meeting ... 2014Oral Scientific SessionPURPOSE/OBJECTIVE(S): Random nasopharyngeal biopsy after completion of intensity-modulated radiation therapy (IMRT) for non-metastatic nasopharyngeal cancer (NPC) is routinely practiced in Hong Kong to confirm local remission. Plasma EBV DNA is proven an accurate marker for NPC. We carried out a prospective study comparing the correlation between post-IMRT nasopharyngeal biopsy and EBV DNA, to investigate if EBV DNA can substitute biopsy to confirm local remission. MATERIALS/METHODS: Patients with non-metastatic NPC treated with definitive (chemo) IMRT diagnosed between January 2011 and March 2013 were recruited. After baseline workup ...postprin

Supportive periodontal care for the Hong Kong population

Supportive periodontal care is an integral and essential element of therapeutic care for patients who have received treatment for periodontitis. The emphasis of supportive periodontal care is on the prevention of periodontal disease recurrence. Dentists, using a team approach, should aim to keep the treated dentition healthy and with proper function. The success of the supportive periodontal care treatment regimen depends to a large extent on the compliance of patients with the regimen recommended, as well as each individual’s risk of periodontal deterioration. This article summarizes the key concepts of supportive periodontal care and discusses the application of this treatment regimen, and by extension the maintenance of dental implants, in the Hong Kong population. Practical issues and future directions are also discussed

A relational approach to counterfeit reduction: evidence from China

Conference Theme: Marketing in the Age of DataCounterfeiting is a complex, institutional-ridden phenomenon particularly prevalent in emerging markets such as China. Applying the institutional theory, this study examines how relational mechanisms (with distributors and governments) may lead to counterfeit reduction. Through a multi-informant survey (directors and marketing managers) from 271 foreign firms in China, we depict the interplay between firms’ relational ties and appropriate internal mechanisms on counterfeit reduction. We theorize that firms can leverage distributor and government ties to curtail counterfeiting; yet they should simultaneously align internal mechanisms that correspond to the time orientation of different relational ties such that embedded values in the two relationships can be effectively extracted for better counterfeit reduction outcomes
