In the county of Stockholm, between 1970 and 2002, we have previously reported a 3-fold parallel increase in the incidence of tonsillar squamous cell carcinoma (SCC) and the proportion of human papillomavirus (HPV) positive tonsillar SCC. Here, we have followed the above parameters in all patients (n = 120) diagnosed with tonsillar SCC during 2003-2007 in(More)
Smoking and alcohol are well-known etiological factors in tonsillar cancer. However, as in cervical cancer, human papillomavirus (HPV) is currently found in a sizable proportion of tonsillar cancer. Recent reports from the U.S. and Finland show an increase in the incidence of tonsillar cancer, without a parallel rise in smoking and alcohol consumption. This(More)
The aim of our study was to investigate the physical state and the viral load of HPV-16 in tonsillar cancer and to correlate these findings with clinical outcome. To distinguish between integrated and episomal forms of HPV, 22 fresh-frozen tonsillar cancer samples were analysed by a method based on restriction enzyme cleavage, ligation and PCR (rliPCR).(More)
OBJECTIVES The protein calprotectin (S100 A8/A9) is present in neutrophils, monocytes, and macrophages. Colorectal inflammation can be detected by increased excretion of fecal calprotectin (FC). The aim of this study was to evaluate FC as a quantitative marker of inflammatory activity in children with inflammatory bowel disease (IBD). PATIENTS AND METHODS(More)
PURPOSE Abdominoperineal excision (APE) of the rectum and anus for rectal cancer continues to have greater local recurrence and poorer survival than that seen following anterior resection. Changing to an extended prone perineal dissection results in a more cylindrical specimen and should improve outcomes. PATIENTS AND METHODS One hundred twenty-eight(More)
Numerous reports have shown that the incidence for oropharyngeal cancer is increasing and that human papillomavirus (HPV) is a risk factor. However, few studies have investigated the specific subsites of the oropharynx. Following our previous research on tonsillar cancer, we assessed the increase in the incidence of base of tongue cancer and the prevalence(More)
From 1970 to 2002 in the Stockholm area, we revealed a parallel three-fold increase in the incidence of tonsillar cancer and the proportion of human papillomavirus (HPV) positive tonsillar cancer cases, indicating a possible role of HPV infection in this disease. We have now examined whether HPV and viral load in pre-treatment tonsillar cancer biopsies(More)
OBJECTIVES A sharp increase in paediatric (younger than 16 years) inflammatory bowel disease (IBD) incidence was observed in northern Stockholm County, Sweden, in 1990-2001. The increasing incidence was primarily explained by a rising incidence of Crohn disease (CD). Here, we present an update on the trends in incidence of paediatric IBD, 2002-2007. (More)
BACKGROUND/AIMS We investigated the impact of diabetes mellitus type 2, overweight, alcohol over-consumption, and chronic hepatitis B or C as risk factors, for liver fibrosis in psoriasis patients treated with methotrexate. METHODS One hundred and sixty-nine liver biopsies from 71 patients who underwent liver biopsies as part of the monitoring of(More)
BACKGROUND Human papilloma virus (HPV), which is frequently present in tonsillar carcinoma seems to be a prognostically favourable factor for patient survival and also for low risk of relapse. Since HPV may abrogate the function of wild type p53 and hence influence radiosensitivity we attempted to analyse if HPV and p53 status in tonsillar carcinoma(More)
