- BK-virus (BKV) associated nephropathy (BKVAN) and BKV associated haemorrhagic cystitis (HC) are complications of BKV infection/reactivation in renal and allogeneic haematopoietic stem cell transplantation (HSCT) patients, respectively. The task of how to manage these diseases was given to the chair by the Swedish Reference Group for Antiviral Therapy (RAV). After individual contributions by members of the working group, consensus discussions were held in a meeting on 23 January 2018 arranged by RAV. Thereafter, the recommendations were published in Swedish on November 2018. The current translation to English has been approved by all co-authors. High BKV serum levels suggest an increased risk for BKVAN and potential graft failure. For detection of BKVAN, careful monitoring of BKV DNA levels in serum or plasma is recommended the first year after renal transplantation and when increased creatinine serum levels of unknown cause are observed. Notably, a renal biopsy is mandatory for diagnosis. To reduce the risk for progression of BKVAN, there is no specific treatment, and tailored individual decrease of immunosuppression is recommended. For BKV-HC, BKV monitoring is not recommended, since BK-viruria frequently occurs in HSCT patients and the predictive value of BKV in plasma/serum has not been determined. However, the risk for BKV-HC is higher for patients undergoing myeloablative conditioning, having an unrelated, HLA-mismatched, or a cord blood donor, and awareness of the increased risk and early intervention may benefit the patients. Also for BKV-HC, no specific therapy is available. Symptomatic treatment, e.g. forced diuresis and analgesics could be of use.

- CONCLUSIONS: The incidence of tonsillar cancer in Sweden is increasing, particularly among men. Risk factors other than smoking may have contributed to the observed secular trend in men. In women, however, smoking can be a part of the explanation. Further studies to look at changes in other environmental factors, such as human papilloma virus (HPV) infection, are clearly warranted. OBJECTIVES: Head and neck cancer is related to smoking habits and smoking has decreased substantially during the last 30 years in Sweden. However, there is suspicion that the incidence of tonsillar cancer has increased in the last 30 years as it has in the USA and Finland, in spite of reduced prevalence of known risk factors. The time trends of oral and oropharygeal cancer have been studied in Sweden, but not tonsillar cancer specifically. SUBJECTS AND METHODS: We used the Swedish Cancer Registry to assess the secular trend of incidence of tonsillar cancer in Sweden since 1960. For comparison we investigated the incidence of other oral cancers and lung cancer, which are also smoking-related. The prevalence of smoking was investigated for reference. Age-standardized incidence rates were calculated and linear regression was used to evaluate secular trends. RESULTS: The incidence of tonsillar cancer increased by 2.6% per year in men and 1.1% in women. No similar increase was seen in the other oral cancers. For lung cancer there was a decrease in the incidence in men, but in women the incidence is still increasing.
