- To assess B12 and folate deficiency after continent urinary diversion via a Kock continent urinary reservoir in children and adolescents.Ten boys and 10 girls (10.8-18 years old at surgery) were operated with a Kock reservoir and followed for 5-12 years (mean 8.5). The follow-up period was divided into early (3 months-5 years, EFU) and late (5-12 years, LFU) follow-up. Patients were investigated for haemoglobin, serum iron, total iron binding capacity (TIBC), serum Vitamin B12, serum and blood folate, methylmalonic acid (MMA), homocystine and glomerular filtration rate.Two patients developed subnormal B12 values (median 107.5 pmol/l), one at the EFU, and the other at LFW. The B12 value decreased during the LFU compared to the EFU in nine patients, but it was still within the normal range. Two patients with renal impairment had elevated MMA with normal B12 values. Five patients had high values of homocystine with folate deficiency and/or B12 deficiency and renal impairment. Plasma folate mean value was normal during the whole follow-up. Blood folate was below normal in five patients at the EFU. Two of these five patients, in addition to three patients, had low values at the LFU. Three of four patients with remaining short terminal ileum (20-45 cm) had normal B12 values at both the EFU & LFU and one had low values at the LFU. Six patients had subnormal GFR at the LFU.To a similar degree as in adults, Vitamin B12, folate and iron deficiency can occur in children and adolescents after continent urinary diversion using an ileal segment. Therefore, Vitamin B12 and folate should be monitored regularly in these patients. Serum MMA and homocystine may offer increased detection of Vitamin B12 deficiency, especially in the patients with normal renal function. Vitamin B12 deficiency is neither correlated with the time elapsed since surgery, nor with the ileum length. Patients are usually asymptomatic, so patients with true B12 deficiency should be identified and placed on life-long Vitamin B12 therapy. An adequate synthetic folic acid as supplements or fortified food is recommended for patients with folate deficiency.

- Objective: At presentation of prostate cancer, patients with proven lymph node metastasis (N1) are comparatively rare. It is difficult to give prognostic information based on the present literature. The aim of this study was to evaluate the impact of known risk factors in patients with pelvic node involvement and without distant metastasis. Methods: From the population-based, prospective prostate cancer tumour registry of the South–East Region in Sweden, we collected data on all 181 patients with N1, M0 prostate cancer diagnosed from January 1987 to October 2000 with a follow-up to December 2001. Mean follow-up was 62 months. Pre-operative risk factors as age, T-category, serum PSA, tumour grade and also primary treatment given was correlated to the outcome. Results: Median age at diagnosis was 65 years. Cancer-specific survival was highly variable with 5-year survival of 72%, a median of 8 years and the projected 13-year figure was 31%. T-category, age, PSA or treatment did not affect the outcome while poorly differentiated tumours had a tendency towards lower cancer-specific survival (p=0.0523) when compared to well and moderately differentiated tumours. Conclusions: This population-based cohort of prostate cancer patients with pelvic node involvement treated principally with non-curative intent had a median cancer-specific survival of 8 years. Preoperatively known risk factors seem to have but a modest impact on the prognosis for patients in this stage of the disease.

- Objective: The influence of specific symptoms on emotions and social activities in the individual patient vanes. Little is known about this variation in urinary bladder cancer survivors (in other words, about the relative importance of sources of symptom-induced distress). Methods: We attempted to enrol 404 surgical patients treated with cystectomy and a conduit or reservoir in four Swedish towns (Stockholm, Orebro, Jonkoping, Linkoping), 101 surgical patients treated with cystectomy and orthotopic neobladder at the Herlev Hospital in Copenhagen, Denmark, and 71 patients treated with radical radiotherapy for bladder cancer, as well as 581 men and women controls in Stockholm and Copenhagen. An anonymous postal questionnaire was used to collect the information. Results: A total of 503 out of 576 (87%) treated patients and 422 out of 581 (73%) controls participated but 59 patients were excluded. The primary source of self-assessed distress among cystectomised patients was compromised sexual function, reduced intercourse frequency caused great distress in 19% of the conduit patients, 20% of the reservoir patients and 19% of the bladder substitute patients. The primary source of self-assessed distress in patients treated with radical radiotherapy was symptoms from the bowel, 17% reported great distress due to diarrhoea, 16% due to abdominal pain, 14% due to defecation urgency and 14% due to faecal leakage. The highest proportion of subjects being distressed was 93% (substantial: 43%, moderate: 29% and little: 21%) for treated upper or lower urinary retention (indwelling catheter or nephrostomy). Conclusion: The distress caused by a specific symptom varies considerably and the prevalence of symptoms causing great distress differs between treatments in bladder cancer survivors. It is possible that patient care and clinical research can be made more effective by focusing on important sources of symptom-induced distress. (C) 2003 Elsevier Science B.V. All rights reserved.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Objective: To get information on the distribution of stone burdens in an average and representative group of Swedish stone forming patients requiring active removal of stones from the kidneys or ureters and to compare different methods for assessing the stone burden. Methods: A computerised device was used to measure the total stone surface area (Ameasured) of 599 stone situations in kidneys and ureters in a consecutive group of patients referred to active stone removal. These measurements were compared with the large and short transverse diameters of the greatest stone, the sum of the largest diameters of the stones, the arithmetically calculated surface area (Acalculated) as well as with the stone-types (A-F) previously described. Result: There were 483 stone situations with one and 116 with more than one stone. The stones were found in 407 men and 192 women. In 343 cases were the stones on the left side and in 256 on the right side. There were 34 staghorn stones. Of the examined stone situations 250 were in the kidney and 349 in the ureter. An Ameasured above 300 mm2 was recorded in 7% of all stone situations. The corresponding numbers for Ameasured above 200 mm2, 500 mm2 and 700 mm2 were 13%, 4% and 3%, respectively. When staghorn stones were excluded, good correlations were recorded for all variables but the best correlation was found between Ameasured and Acalculated. A revision of the previously published stone-type subgroups is suggested based on the following limits for the stone surface area: A = 30 mm2, B = 31-300 mm2, C = 301-700 mm2 and D > 700 mm2. Conclusion: The distribution of stone situtations with different stone burden in an average Swedish population is described. With the exception of staghorn stones and stones with extremely irregular form an acceptable estimate of the stone surface are can be arithmetically derived from the length and the width of the stone. © 2003 Elsevier Science B.V.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To evaluate the cumulative risk of having a prostate cancer diagnosis in a repeated screening situation in relation to the free-to-total prostate specific antigen ratio (F/T-PSA). Patients and Methods: The present study includes 1385 men (aged 50-70 years) who underwent prostate biopsy for the first time in the screening program that started in 1995. In case of a benign finding, the men have been followed biennially and new biopsies performed in case of persistently elevated PSA. The cumulative risk to be diagnosed with prostate cancer until July 1, 2002 was calculated by the Kaplan-Meier method and comparison was made between different levels of T-PSA and F/T-PSA ratios. Results: Of 2129 biopsies 469 showed cancer. The cumulative 5-year risk to be diagnosed with prostate cancer was significantly dependent of the F/T-ratio. The risk for men with a T-PSA of 3-5.99 ng/ml was 16% [6-25%] for those who had a ratio of >30% and 44% [34-60%] for those with a ratio of <10%. The corresponding difference for patients with a T-PSA of 6-9.99 ng/ml was even more pronounced: 21% [0-42%] vs. 80% [64-96%]. Conclusion: By completing the T-PSA measurement with the F/T-PSA ratio it is possible to significantly better assess the cumulative prostate cancer risk within the next five years (without the aid of further urological work-up).
