Objective To study the lifetime occurrence of prostatitis in Finnish men and their exposure to the disease. Subjects and methods A population-based cross-sectional survey was conducted in the two most northerly provinces of Finland (Oulu and Lapland). Altogether, 2500 male residents aged 20±59 years were chosen at random to complete a questionnaire on prostatitis. The data were collected between June 1996 and October 1997. Replies were received from 1832 men, giving a response rate of 75%. Results The overall lifetime prevalence of prostatitis was 14.2%. The risk of having or having had prostatitis increased with age, being 1.7 times greater in men aged 40±49 years than in those aged 20±39 years, and 3.1 times greater in those aged 50±59 years. The overall incidence was 37.8/10 000 person years. More than a quarter of the 261 men who had or had had prostatitis symptoms (27%) suffered from them at least once a year, while 16% suffered from persistent symptoms; 63% of the men with prostatitis had their worst symptoms during the winter (November-March). Neither education nor profession had much in¯uence on the occurrence of prostatitis, but divorced and single men had a lower risk than married men. Most patients felt they had not received enough information about the disease at their ®rst visit to a general practitioner. Conclusions The results of this survey showed that the occurrence of prostatitis symptoms in men living in northern Finland is higher than that reported in other parts of the world. This could be partly caused by the cold climate.
Objective To determine the occurrence of mental distress related to prostatitis in Finnish men. Subjects and methods A population-based cross-sectional survey was conducted of 2500 men aged 20±59 years living in the two northernmost provinces of Finland (Oulu and Lapland). The ®nal response rate was 75% (1832 men). Results The fear of undetected prostate cancer was reported by 17% of the men in the population who had had prostatitis, a value signi®cantly higher (P<0.001) than in healthy men. Fears of having a sexually transmitted disease and suicidal thinking were also slightly more common. The men who had had prostatitis preferred to be alone in a public toilet during voiding (58% vs 44%, P<0.001). Erectile dysfunction was reported by 43% of the men with symptomatic prostatitis and decreased libido by 24%. Self-assessment of personality, adjusted for age, showed that the men with prostatitis were more often busy and nervous than the healthy controls (P<0.001), and that they had a more meticulous attitude to life and its problems. Marital dif®culties were reported by 17% of the men who had had prostatitis at some point in their lives, and 4% were convinced that their illness had caused their divorce. Socio-economic status and social well-being had no apparent in¯uence on the occurrence of prostatitis. Conclusions This survey showed that psychological stress is common in men with prostatitis. Urologists and general practitioners should consider that a consultation with a psychiatrist may be appropriate for selected men with prostatitis.
BackgroundThis study was performed to evaluate the impact of baseline characteristics and treatment methods on the outcome of sporadic renal angiomyolipoma (AML).MethodsThis was a pooled analysis of individual data of 441 patients with AML retrieved from 58 studies and 3 institutional series.ResultsNinety-three patients underwent nephrectomy, 163 partial nephrectomy/enucleation, 128 embolisation, 19 cryoablation, 6 radiofrequency ablation, and 32 conservative treatment. Their mean follow-up period was 44.5 months. Patients who experienced major bleeding at presentation had significantly larger tumours than did those without bleeding (mean diameter, 10.1 vs. 5.9 cm, respectively; p < 0.0001). A total of 9.4 % and 26.4 % of bleeding tumours had a diameter of <4 and <6 cm, respectively. A tumour diameter of ≥8.0 cm (hazard ratio, 2.07; 95 % confidence interval, 1.20–4.77) and the treatment method (p = 0.001) were independent predictors of re-intervention. The risk of re-intervention was significantly higher after embolisation, particularly for large tumours (5-year rate of freedom from re-intervention: diameter of ≥8.0 cm, 49.2 %; diameter of <8.0 cm, 74.8 %; p = 0.018). Conservatively treated AMLs had a mean baseline diameter of 3.2 ± 2.7 cm; after 41 months, their mean diameter was 3.7 ± 3.1 cm (p = 0.109).ConclusionsThe prevalence of major bleeding is high in sporadic AMLs with a diameter of >6 cm. These results suggest that conservative treatment can be considered in AMLs of <6 cm in diameter. Among current treatment methods, embolisation was associated with a significantly higher risk of re-intervention. Further studies are needed to define risk factors for bleeding and assess the relative benefits of different treatment modalities.
OBJECTIVESTo provide a fluent and easily comprehensible Finnish version of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and to study its linguistic validity and correlation with a visual pain scale (VAS). PATIENTS AND METHODSThe double-back translation method with two interim modifications was used to produce the Finnish version of the NIH-CPSI. The validity was tested by presenting the questionnaire to 155 men with clinically confirmed chronic pelvic pain syndrome (CPPS) and 12 controls with no previous urological symptoms. Convergent validity of the NIH-CPSI was tested by determining the correlation between the Finnish NIH-CPSI and VAS. Patients' and urologists' opinions about the utility of the Finnish NIH-CPSI were also reviewed. RESULTSThe total Finnish NIH-CPSI scores and the pain domain and voiding symptom domain scores differed significantly ( P < 0.001) between the groups, suggesting good discriminant validity of the symptom index. The NIH-CPSI scores correlated well with the VAS (Pearson's correlation 0.76). The preciseness and comprehensibility of the questionnaire were consistently evaluated to be 'good' or 'excellent' both by patients and urologists. CONCLUSIONSThe Finnish version of the NIH-CPSI is valid and easily comprehensible for measuring CPPS symptoms. In addition, it provides good discriminant and convergent validity in distinguishing CPPS symptoms and should be used as primary outcome measure in CPPS studies. Authors from Finland have assessed a version in their language of theNational Institutes of HealthChronic Prostatitis Symptom Index; they found that their translated version was valid and easily understandable in the management of the symptoms of chronic pelvic pain syndrome. They felt it should be used as a primary outcome measure in studies with these patients.There are three papers in this issue relating to the effect of drugs on LUTS; the first of these is a pooled analysis of three double-blind placebo-controlled studies into the safety and efficacy of the 10 mg dose of alfuzosin. The second evaluates the effect on quality-oflife issues of treatment with dutasteride. Finally, authors from Australia compare the effect of a Serenoa repens extract with placebo for LUTS. M . J .

Our aim was to establish the Estonian version of the National Institutes of Health chronic prostatitis symptom index (NIH-CPSI), and to examine its validity and applicability in chronic prostatitis patients as well as in community-based study. The questionnaire was tested in 54 category III prostatitis patients. In addition, 452 men were enrolled into a community-based study that resulted in 83 completed questionnaires. The discriminatory power, psychometric properties and internal correlations of the questionnaire were tested. The questionnaire demonstrated good internal consistency, with Cronbach's alpha coefficient 0.82. The pain and quality of life domains demonstrated high correlations with each other and with the entire questionnaire. The total score and the scores of pain and quality of life domains of the Estonian NIH-CPSI differed significantly between the chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) patients and the men without CP/CPPS, and so the index proved a good discriminant validity. We can conclude that the Estonian NIH-CPSI is easily understood and reflects accurately the clinical symptoms and the quality of life in patients with chronic prostatitis. The similarity of the psychometric properties of the English and Estonian versions of the NIH-CPSI supports their measurement equivalence.
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), is of considerable interest in clinical urology. During the past decade, several new approaches have been made to discover its aetiology and pathophysiological mechanisms and to develop treatment modalities. The aetiology of CPPS has remained unresolved. Bacterial, chemical, urodynamic and immunological aetiologies have been suggested, but none of these has been conclusively proven. The histopathological changes in CP and CPPS are relatively well known, but the pathophysiological changes that lead to chronic inflammation and prolonged symptoms are still poorly understood. This review proposes an additional approach to the pathophysiology of CPPS. The concept of prostate tissue pressure is introduced as an objectively measurable parameter in evaluating the inflammatory process in CPPS. Chronic pain due to neurogenic inflammation and altered mast cell function is also discussed.
BackgroundDespite widespread occurrence and poor comprehension, prostatitis has been largely under‐researched.ObjectiveTo compare complaints, general and sexual health, co‐morbidities, risk factors, and lifestyle in men with and without prostatitis‐like symptoms (PLS).Material and methodsThe cross‐sectional study included 20‐ to 59‐year‐old male residents of Estonia. Questionnaire data of 82 men with PLS and of 711 men without PLS were compared.Results and discussionA third of men with PLS considered their health poor, with more frequently diagnosed renal diseases, benign prostate hyperplasia, STDs, chronic nervous system diseases, and depression in them than in controls. They reported more cystitis and gynecological inflammations in their partners, and more prostatitis in their close relatives. This familial predisposition indicates possible genetic and immunologic background of PLS that may be associated also with susceptibility to respiratory tract infections revealed for the first time in our study. By the personality type, the men in the PLS group were less calm but more worrying. Hard drinks, antidepressants, sedative, and sleeping pills were more frequently consumed, and nightshift working and continuous stress were more commonly seen among men with than without PLS. PLS disturbed the sexual life as well as everyday activities.ConclusionsThe men with PLS are characterized by remarkable complex of co‐morbidities, habits, and attitudes. PLS possess substantial negative impact on quality of life. Successful work‐up of these patients needs multidimensional treatment modalities that take into consideration major factors of syndrome. Genetic factors and central nervous system imbalance but also partner's genital tract microbiota as the potential contributing and/or perpetuating factors to PLS need more scientific attention.
