Many clinico- pathological analyses of macroscopic findings have been described, although the clinical findings of oral candidiasis vary considerably and the conditions are complex. The present study analyzes the distribution, clinical, cytological and histological diagnoses of oral candidiasis, associated complex diseases and the di-agnostic value of cytology. The ratio of Candida in-fection was 28.9% among 1551 study participants. Females were infected significantly more often than men (p < 0.01) and the affected age range was 60 - 79 years (61.0%, p < 0.01). The predominantly affected areas were the tongue (48.3%, p < 0.01) and gingiva (20.0%, p < 0.01), and occurrence at multiple loci was seen in 43 (9.6%) patients. The typical clinical find- ings of oral candidiasis were ulcerative/erythematous lesions (33.2%, p < 0.01) and pseudomembranous candidiasis (31.6%, p < 0.01). A histopathological dia- gnosis of candidiasis based on biopsy specimens from 26 lesions in patients with Candida infection indicated by cytology was confirmed from cultures. The break- down of a cytological to a definite diagnosis was 6 positive (SCC 4, verrucous carcinoma 1, moderate to severe dysplasia 1), 6 suspected positive (mild dyspla- sia, 2;moderate to severe dysplasia, 2;papilloma, 1 and SCC, 1) and 14 negative (epulis, 3;papilloma, 3;granulation tissue, 2;fibrosis, 2 and others, 4). Exfo-liative cytology can easily judge the presence of Can-dida species, although experience is necessary for the presumptive diagnosis of an oral mucosal disease. The application of exfoliative cytology using the Pe- riodic acid-Schiff reaction is helpful for the earlier detection of oral candidiasis with various macrosco- pic findings.展开更多

Methods: A self-administered written questionnaire was forwarded to 709 prostatectomized patients from the Aarhus Prostate Cancer Study containing questions about cases of prostate cancer (PC), age at diagnosis, vital status, and age at death for all first-degree relatives. Patients were then divided into groups according to their family history: hereditary prostate cancer (HPC), familial prostate cancer (FPC), and sporadic prostate cancer (SPC) groups. The information from a subset of both FPC (n = 17) and SPC (n = 17) groups were validated in the Danish Cancer Register and the Civil Registration System. Between groups, we described the association of age, prostatespecific antigen (PSA), postoperative Gleason score and T Stage. A Kaplan-Meier curve demonstrated postoperative disease-free survival in each group. Results: The response rate was 81% (574/709). About 21% of the patients were categorized in the FPC group, of which 7% were identified as having HPC. The median follow-up time was 63 months for HPC, 65 months for FPC and 88 months for SPC. Overall, there was no significant difference between groups in clinical features and disease-free survival except that patients with HPC were significantly associated with younger age than sporadic cases (p = 0.02). The proportion of self-reported PC diagnoses confirmed in the cancer register was 27.8%. The index persons with SPC reported no PC in first-degree relatives and none was found the cancer register. Conclusion: Overall, we found no difference in clinical characteristics and survival, following radical prostatectomy except that patients with HPC were younger at diagnosis. These results are in line with previously reported data.展开更多
