Cyclosporin- and nifedipine-induced gingival overgrowth in renal transplant patients: correlations with periodontal and pharmacological parameters, a…
1996
The factors associated with cyclosporin A (CsA)- and nifedipine (Nif)-induced gingival overgrowth were investigated in 113 renal transplant recipients receiving CsA alone (Group 1) [n = 61], CsA and Nif (Group 2) [n = 28], or azathioprine (Aza) (Control Group) [n = 24]. Periodontal and pharmacological parameters were assessed for each patient. The patients with a gingival overgrowth index (GOI) score1 were considered responders (R); those with a score/= 1 were non-responders (NR). Gingival overgrowth occurred in 33.7% of the patients in Groups 1 and 2; 60% of the responders were receiving CsA+Nif. In R, no relationship was found between the GOI and the periodontal and pharmacological parame…
Differences in incidence and survival of oral cavity and pharyngeal cancers between Germany and the United States depend on the HPV-association of th…
2017
Abstract Introduction The epidemiology of squamous cell oral cavity and pharyngeal cancers (OCPC) has changed rapidly during the last years, possibly due to an increase of human papilloma virus (HPV) positive tumors and successes in tobacco prevention. Here, we compare incidence and survival of OCPC by HPV-relation of the site in Germany and the United States (US). Materials and methods Age-standardized and age-specific incidence and 5-year relative survival was estimated using data from population-based cancer registries in Germany and the US Surveillance Epidemiology and End Results (SEER) 13 database. Incidence was estimated for each year between 1999 and 2013. Relative survival for 2002…
Population attributable risk of tobacco and alcohol for upper aerodigestive tract cancer.
2011
Tobacco and alcohol are major risk factors for upper aerodigestive tract (UADT) cancer and significant variation is observed in UADT cancer rates across Europe. We have estimated the proportion of UADT cancer burden explained by tobacco and alcohol and how this varies with the incidence rates across Europe, cancer sub-site, gender and age. This should help estimate the minimum residual burden of other risk factors to UADT cancer, including human papillomavirus. We analysed 1981 UADT cancer cases and 1993 controls from the ARCAGE multicentre study. We estimated the population attributable risk (PAR) of tobacco alone, alcohol alone and their joint effect. Tobacco and alcohol together explaine…
Preoperative chemoradiation may not always be needed for patients with T3 and T2N+ rectal cancer
2011
BACKGROUND: Preoperative chemoradiation is becoming the standard treatment for patients with locally advanced rectal cancer. However, since the introduction of total mesorectal excision (TME), local recurrence rates have been reduced significantly, and some patients can be spared from potentially toxic over treatment. The current study was designed to assess the factors that predict recurrence in an institutional series of patients with rectal cancer who had clinical T2 lymph node-positive (cT2N+) tumors or cT3N0/N+ tumors and underwent radical surgery without receiving preoperative chemoradiation. METHODS: Between November 1997 and November 2008, the authors' multidisciplinary group preope…
Efficacy of mometasone furoate microemulsion in the treatment of erosive-ulcerative oral lichen planus: pilot study
2004
Background: Oral lichen planus (OLP) is a frequent immunological chronic disease, having different clinical forms: asymptomatic and symptomatic. Symptomatic OLP has been palliated with topical corticosteroids with different levels of efficacy and safety. The purpose of this pilot phase II clinical trial was to determine the efficacy of mometasone furoate microemulsion upon the symptoms and signs of erosive-ulcerative OLP. Methods: Forty-nine patients with clinical and histologically confirmed erosive-ulcerative OLP were enrolled in this study (36 women and 13 men). Their average age was 56.4 years (from 28 to 78). The treatment consisted of 0.1% mometasone furoate microemulsion mouthwash …
Implication of the Examining Pathologist to Meet the Oncologic Standard of Lymph Node Count after Laparoscopic Lymphadenectomy
2010
<i>Objective:</i> The lymph node number as benchmark in oncologic operations depends on the patient’s anatomy, surgeon’s skill and pathologist’s accuracy. The influence of the pathologist is barely evaluated. <i>Methods:</i> A retrospective analysis of lymph node numbers after 700 laparoscopic lymphadenectomies in correlation to the examining pathologists was done. Three surgeons from the same department performed all operations at 2 campi, where 2 separate pathology institutions exist. Lymph node specimens were assigned randomly to any of the 62 involved pathologists. <i>Results:</i> The mean number of lymph nodes was equal for all surgeons. Lymph node s…
Incidence of lip malignancies in Germany-data from nine population-based cancer registries.
2017
Background The objective of this study was to analyse the incidence of lip malignancies in Germany. Methods Data from population-based cancer registries covering a population of 39 million inhabitants from 14 federal states were pooled. Lip malignancies were classified according to the International Classification of Diseases (ICD-10). Age-standardised incidence rates and annual percentage changes in the incidence trends of lip cancer (C00), melanoma of the lip (C43.0), and non-melanoma skin cancer of the lip (C44.0) were calculated. Results Lip cancer (C00) incidence rate was 0.57/0.15 per 100 000 (men/women) in 2003 and 0.52/0.18 in 2012. In women, the change was statistically significant…
Salivary flow and xerostomia in patients with type 2 diabetes
2018
Background: Saliva is secreted by the major and minor salivary glands. There are a number of physiological factors that can reduce this secretion such as age, sex, body weight, number of teeth present in the mouth or time of day. This decrease may also be caused by the use of certain drugs, radiotherapy for head and neck cancer, chronic rheumatic diseases such as Sjögren's syndrome and other systemic disorders such as diabetes mellitus (DM). Objective of this study was to investigate the effect of type 2 DM on salivary secretion and its relation to the sensation of xerostomia. Methods: Forty-seven patients with type 2 DM and 46 healthy individuals, aged 40-80, participated in the study. Sam…
Surgery-triggered and non surgery-triggered Bisphosphonate-related Osteonecrosis of the Jaws (BRONJ): A retrospective analysis of 567 cases in an Ita…
2011
Invasive local procedures are often reported in clinical history of patients suffering from Bisphosphonates-Related Osteonecrosis of the Jaws (BRONJ) but over 40% of spontaneous forms have been also described in literature. We compared age, gender, underlying bone disorders, bisphosphonate therapy, clinical features and surgical outcome of 205 cases (36.2%) of BRONJ non surgery-triggered (group 1) with 362 (63.8%) cases of surgery-triggered forms (group 2). Differences between group 1 and 2 were analysed using Mann-Whitney U and χ2 tests. Statistical analysis was performed using STATA 8. Zoledronate was the most used type of bisphosphonate (63.4% versus 69.0%) and the mandible was the most …
Radiation response non-invasively imaged by [18F]FDG-PET predicts local tumor control and survival in advanced oral squamous cell carcinoma
2003
It is a major challenge to preoperatively identify patients who will profit from surgery of advanced oral cancer. In multimodality therapy, response to neoadjuvant radiation correlates to treatment success. Hence, for preoperative decisions, assessment of treatment response is required. Therefore, we analysed the prognostic significance of glucose metabolism after preoperative radiotherapy. [(18)F]FDG-PET investigations were performed for re-staging 35 patients after neoadjuvant radiotherapy (36Gy) immediately prior to tumor resection. Emission and transmission measurements were obtained and SUV's were calculated for the sites of maximum [(18)F]FDG-uptake. Subpopulations of "low" (SUV4) and…
