Measuring progress against cancer in Europe: has the 15% decline targeted for 2000 come about?

BACKGROUND: Against a background of increasing cancer rates in the mid-1980s, Europe Against Cancer launched an ambitious programme aiming to reduce cancer mortality by 15% by the year 2000. A programme of activities and research, focussing on three major themes [prevention (particularly tobacco control), screening, and education and training], was developed together with the European Code Against Cancer. METHODS: To evaluate the outcome of the programme, all cancer mortality data were abstracted for each member state of the European Union (EU) until the most recent year available. For each gender group in each member state, age-specific rates were estimated for 2000. For each country-gender grouping, the standardized mortality rate (SMR) and expected numbers of deaths in 2000 were calculated based on the age-specific rates for 1985 and the population estimates for 2000. The ratio of the SMR in 2000 to that of 1985, was used as the measure to compare mortality rates. RESULTS: In 1985, there were 850 194 cancer deaths in the EU. Based solely on demographic considerations, this number was expected to rise to 1 033 083 in the year 2000. Between 1985 and 2000, the number of cancer deaths increased in both men (+12%) and women (+9%). The target of a 15% reduction in the expected numbers of cancer deaths in the EU was not met, although the 10% reduction in number of deaths expected in men and 8% in women, along with a 11% reduction in risk of cancer death in men and a 10% reduction in women, was noteworthy. Only Austria and Finland achieved the 15% reductions in deaths in both men and women. The UK and Luxembourg (where the small population and annual number of deaths make interpretation difficult) came close to meeting these targets, as did Italy. Portugal and Greece had the poorest performance, with increases in each gender group. CONCLUSIONS: Cancer deaths in the EU were expected to rise from 850 194 in 1985 to 1 033 083 in 2000. It is estimated that there will be 940 510 cancer deaths that year, due to the decline in risk observed since 1985. The Europe Against Cancer programme appears to have been associated with the avoidance of 92 573 cancer deaths in the year 2000. With few exceptions, most countries are experiencing declining trends in cancer death rates, which seem set to continue, at least in the near future. Renewed tobacco control efforts are clearly needed for women, and there is a strong case for the introduction of organized breast and cervix screening programmes in all member states. Continuing to emphasize prevention within cancer control will help to promote the continuing decline in death rates in the future.

The prevalence of male urinary incontinence in four centres: the UREPIK study.

OBJECTIVES: To report the results of the prevalence and health status associated with male urinary incontinence (UI) in a population-based, multicentre study in four countries, and to assess the epidemiology of this condition. SUBJECTS AND METHODS: A standard questionnaire asking about frequency and amount of urine loss, use of pads and stress incontinence, was used to measure the prevalence of UI among men in four countries (Boxmeer, The Netherlands; Auxerre, France; Birmingham, UK; and Seoul, Korea). Self-reported urinary leakage was also recorded, with details of visits to the doctor for the symptoms. The samples were selected randomly from population registers of men aged 40-79 years, which provided representative samples in each community. RESULTS: In all, 4979 men responded; from incontinence symptom scores, 7.3% of men aged 40-79 years in Auxerre, 16.3% in Boxmeer, 14.4% in Birmingham and 4.3% in Seoul reported mild to severe UI. On a self-reported question, 14.8% and 14.5% of men in Birmingham and Boxmeer thought that they had urinary leakage, compared with 7.5% and 7.1% of men in Auxerre and Seoul, but typically the reported incontinence was leaking drops of urine a few times a week. Of men with urinary leakage in the three European centres, 25.9% visited the doctor with this problem, compared with only 9.0% of men in Seoul. Of men in the European centres, 5.9% used pads at least occasionally, compared with only 1.6% of men in Seoul. UI was age-related and the reporting of it varied among centres, with 14.4% of men in Birmingham and 12.7% of men in Boxmeer aged 40-49 years reporting mild to severe UI, compared with 5.2% in Auxerre and 1.9% in Seoul. Among men aged 60-69 years the corresponding percentages were 13.7% in Birmingham, 22.6% in Boxmeer, 9.2% in Auxerre and 8.0% in Seoul. CONCLUSIONS: UI is more common in older men and relatively uncommon among younger men. Some men reported no problems on the symptom questionnaire but replied positively to a direct question. Surprisingly many men wear protective pads at least occasionally as a result of their problem. UI appears to be a problem for men and which remains largely untreated; this may partly be a result of cultural differences.

Meta-analysis of clinical trials of Cyclo 3 Fort in the treatment of chronic venous insufficiency.

AIM: Chronic venous insufficiency (CVI) of the lower limbs is a major cause of morbidity and varicose veins affect 20% to 60% of adults in the western world. The treatment of patients with CVI attempts to reduce both clinical symptoms and the development of chronic venous disease. A meta-analysis using data from all clinical trials and studies of Cyclo 3 Fort, a combination of root extract of the Ruscus aculeatus plant (150 mg per capsule), hesperidin methyl chalcone (150 mg) and ascorbic acid (100 mg), was carried out to estimate the overall effect on the symptoms and severity of chronic venous insufficiency. METHODS: The meta-analysis included 20 placebo controlled, randomised, double blind studies and 5 randomised studies against a comparator drug. There were 6 single arm studies of Cyclo 3 Fort alone with no placebo arm. In all studies the response to Cyclo 3 Fort was compared to baseline values. In total there was information from 10,246 subjects. RESULTS: On a 4 point symptom severity scale, where 0 corresponds to no symptoms and 3 to severe symptoms, Cyclo 3 Fort significantly reduces the severity of pain by 0.44 (0.12) points; cramps 0.26 (0.08), heaviness 0.53 (0.11), and paraesthesia 0.29 (0.10) compared to placebo. There is also a significant reduction in venous capacity of 0.70 (0.19) ml/100 ml with Cyclo 3 Fort compared to placebo. We also found reductions in the severity of oedema 0.43 (0.20) points, and decreases in calf and ankle circumference, 0.73 (0.37) cms and 1.17 (0.83) cm, respectively, among patients treated with Cyclo 3 Fort compared to placebo which were not statistically significant. CONCLUSION: Despite questions surrounding the variability of data quality and sample size of some of the studies, we conclude that in patients with CVI Cyclo 3 Fort significantly reduces the severity of the symptoms compared to placebo. This study is a strong and objective demonstration of the clinical efficacy of Cyclo 3 Fort in treating patients with CVI.

[Prevalence of lower urinary tract disorders and incontinence in Auxerre. French segment of the UrEpik study].

OBJECTIVES: To estimate the prevalence of low urinary tract symptoms (LUTS) and urinary incontinence among men and women aged 40 to 79 years. METHODS: A postal survey was carried out in a community-dwelling random sample, in Auxerre, France. LUTS were assessed using the International Prostate Symptom Score (IPSS). Urinary incontinence (UI) was assessed using a score based upon four questions. RESULTS: 1216 men and 591 women participated in the survey. 19.2% of men and 13.7% of women reported moderate to severe LUTS (IPSS > 7). 73% of men and 29% of women suffered from UI. Among men and women reporting severe symptoms of UI (0.4 and 5.4% respectively), one third had been prescribed medications for urinary disorders within the previous six months. CONCLUSION: This survey confirms the high prevalence of LUTS and urinary incontinence among a community-dwelling sample of men and women, and highlights the need for management of these disorders.

Pretargeted adjuvant radioimmunotherapy with yttrium-90-biotin in malignant glioma patients: a pilot study.

In a previous study we applied a three-step avidin-biotin pretargeting approach to target 90Y-biotin to the tumour in patients with recurrent high grade glioma. The encouraging results obtained in this phase I-II study prompted us to apply the same approach in an adjuvant setting, to evaluate (i) time to relapse and (ii) overall survival. We enrolled 37 high grade glioma patients, 17 with grade III glioma and 20 with glioblastoma, in a controlled open non-randomized study. All patients received surgery and radiotherapy and were disease-free by neuroradiological examinations. Nineteen patients (treated) received adjuvant treatment with radioimmunotherapy. In the treated glioblastoma patients, median disease-free interval was 28 months (range=9-59); median survival was 33.5 months and one patient is still without evidence of disease. All 12 control glioblastoma patients died after a median survival from diagnosis of 8 months. In the treated grade III glioma patients median disease-free interval was 56 months (range=15-60) and survival cannot be calculated as only two, within this group, died. Three-step radioimmunotherapy promises to have an important role as adjuvant treatment in high grade gliomas, particularly in glioblastoma where it impedes progression, prolonging time to relapse and overall survival. A further randomized trial is justified.

Low-dose oral methotrexate and cyclophosphamide in metastatic breast cancer: antitumor activity and correlation with vascular endothelial growth factor levels.

BACKGROUND: Anticancer chemotherapy is thought to be effective by means of direct cytotoxicity on tumor cells. Alternative mechanisms of efficacy have been ascribed to several common anticancer agents, including cyclophosphamide (CTX), methotrexate (MTX), anthracyclines and taxanes, postulating an antiangiogenic activity. PATIENTS AND METHODS: We evaluated the clinical efficacy and impact on serum vascular endothelial growth factor (VEGF) levels of low-dose oral MTX and CTX in patients with metastatic breast cancer. MTX was administered 2.5 mg bd on days 1 and 2 each week and CTX 50 mg/day administered continuously. RESULTS: Sixty-four patients were enrolled, 63 were evaluable: Eastern Cooperative Oncology Group (ECOG) performance status 0-1, > or =2 sites of metastatic disease (n = 50 patients), progressive disease at study entry (n = 51), 1 regimen for metastatic disease (n = 32) and > or =2 regimens (n = 20). Among the 63 evaluable patients, there were two complete remissions (CR), 10 partial remissions (PR) for an overall response rate of 19.0% (95% CI 10.2% to 30.9%) and an overall clinical benefit (CR+ PR+ stable disease >24 weeks) of 31.7% (95% CI 20.6% to 44.7%). Grade > or =2 leucopenia was registered in only 13 patients. The median serum VEGF level for the subgroup of patients on treatment for at least 2 months decreased with treatment from 315 pg/ml (95% CI 245 to 435) at baseline to 248 pg/ml (95% CI 205 to 311) at 2 months (P <0.001). Both responders and non-responders showed similar reductions in serum VEGF (P = 0.78). After 6 months patients still on treatment had a median VEGF level of 195 pg/ml (95% CI 96 to 355), which was significantly lower than the median baseline values (P = 0.001). CONCLUSIONS: Continuously low-dose CTX and MTX is minimally toxic and effective in heavily pretreated breast cancer patients. A drop in VEGF was associated with the treatment and so alternative hypotheses, other than that of direct toxicity on tumor cells, must be favored when trying to explain the anticancer effect.

Very young women (<35 years) with operable breast cancer: features of disease at presentation.

BACKGROUND: Breast cancer rarely occurs in young women. Our knowledge about disease presentation, prognosis and treatment effects are largely dependent upon older series. MATERIALS AND METHODS: We evaluated biological features and stage at presentation for 1427 consecutive premenopausal patients aged < or = 50 years with first diagnosis of invasive breast cancer referred to surgery at the European Institute of Oncology from April 1997 to August 2000. A total of 185 patients (13%) were aged < 35 years ('very young') and 1242 (87%) were aged 35-50 years ('less young'). The expression of estrogen receptors (ER), progesterone receptors (PgR), presence of vascular invasion (VI), grading (G), expression of Ki-67, HER2/neu overexpression, pathological stage according to TNM staging system (pTNM), pathological tumor size and number of axillary lymph node involvement were evaluated. RESULTS: Compared with less young patients, the very young patient group had a higher percentage of tumors classified as ER negative (P < 0.001), PgR negative (P = 0.001), higher expression of Ki-67 > or = 20% of cells stained; 62.2% versus 53%, (P < 0.001), vascular or lymphatic invasion (48.6% versus 37.3%, P = 0.006), and pathological grade 3 (P < 0.0001). There was no difference between the two groups for pT, pathological tumor size (pN) and number of positive lymph nodes. CONCLUSIONS: We conclude that compared with less young premenopausal patients, very young women have a greater chance of having an endocrine-unresponsive tumor, and are more likely to present with a higher grade, more extensively proliferating and vessel invading disease. Pathological tumor size, nodal status and number of positive axillary lymph-nodes have a similar distribution among the younger and the older cohorts, thus not supporting previous data indicating more advanced disease in younger patients at diagnosis of operable disease.

Recognizing features that are dissimilar in male and female breast cancer: expression of p21Waf1 and p27Kip1 using an immunohistochemical assay.

BACKGROUND: Male breast cancer (MBC) is an uncommon disease, and most of our current knowledge of its biology, natural history and treatment has been extrapolated from data on the disease in women. Information is still needed on the molecular biological properties of male breast tumors and their predictive relevance. Kinase inhibitor proteins (KIPs) p27Kip1 and p21Waf1 negatively regulate cell cycle progression by preventing the passage of cycling cells from G1 to S phase through G1 cyclin-dependent kinase activation. No studies exist on the role of these factors in male breast carcinoma. PATIENTS AND METHODS: We have retrospectively analyzed the immunohistochemical expression of p21Waf1 and p27Kip1 protein in 27 primary MBC and in 101 female breast cancers (FBC) treated at the European Institute of Oncology between 1997 and 2000. We also assessed sex hormone receptors status, p53, bcl-2 and c-erb-B2 protein expression, and Ki-67 labeling index. RESULTS: We observed a statistically significant difference in the immunostaining of KIPs p27Kip1 and p21Waf1 in male patients compared with females. Expression of p21Waf1 was observed in 19 of the 27 (70.3%) primary MBCs versus 29 of 101 FBC (29%). Fourteen of 22 negative c-erbB-2 MBCs cases expressed immunostaining for p21Waf1 (P = 0.05). p27Kip1 immunoreactivity was been detected in 26 of 27 (96.2%) male breast patients versus 39 of 101 FBC (39.3%) (P = 0.000). Highly positive staining for P27Kip1 was found in 21 of 25 androgen receptor-expressing samples. Higher levels of p27Kip1 were expressed in bcl-2-positive samples (17 of 20). Eighteen of 22 c-erbB-2-negative cases were strongly immunoreactive for p27Kip1. CONCLUSIONS: p27Kip1 and p21Waf1 immunoreactivity is higher in MBCs compared with FBCs. The findings of higher p27Kip1 and p21Waf1 immunostaining may be an additional predictive factor in MBC. These biological features could be possible indicators for different biological pathways in the tumorigenesis of MBCs.

The APTT response of pregnant plasma to unfractionated heparin.

Pregnancy is associated with a physiological increase in coagulation factors and heparin binding proteins; both can affect the activated partial thromboplastin time (APTT) in response to unfractionated heparin (UFH) invalidating the use of a non-pregnant APTT therapeutic range. We compared the anticoagulant response of UFH added in vitro to the plasma of 13 pregnant (third trimester) and 15 nonpregnant women to determine whether the measured APTT and antifactor Xa activities are lower in pregnancy. Increasing concentrations of UFH were added to platelet-poor plasma from each subject and the APTT and anti-factor Xa activity were measured. The amount of UFH which was reversibly bound and neutralised by plasma heparin binding proteins was assessed by comparing the anti-factor Xa activity before and after addition of low affinity heparin (LAH). Fibrinogen, von Willebrand factor antigen (vWF Ag) and factor VIII levels, were also measured. The APTT response, assessed by the slope of the regression line of log APTT versus added heparin concentration, was attenuated in pregnant plasma (0.76 s/U/mL versus 1.2 s/U/mL, p = 0.005) and was highly correlated to increased non-specific plasma protein binding (47% versus 35% p <0.01) and increased fibrinogen (5.1 g/L versus 2.8 g/L, p < 0.01) and factor VIII activity (2.7 U/mL versus 1.2 U/mL, p <0.01). Thus, to achieve the same heparin level, pregnant women require higher daily doses of UFH than non-pregnant women. However, if UFH dose adjustments during the third trimester are based upon a non-pregnant APTT therapeutic range, systematic overdosing of pregnant women will result, possibly increasing the risk of bleeding and osteoporosis.

Urethra-sparing cystectomy and orthotopic urinary diversion in women with malignant pelvic tumors.

BACKGROUND: To the authors' knowledge, few data exist regarding the functional and oncologic outcome of pelvic tumors in women with urethra-sparing cystectomy and orthotopic urinary diversion to the urethra. PATIENTS AND METHODS: The combined data of 102 women age 28-79 (mean, 59 yrs) years who underwent a urethra-sparing cystectomy and orthotopic urinary diversion for either primary bladder cancer (96 patients), carcinoma of the uterine cervix (2 patients), carcinoma of the vagina (1 patient), primary fallopian tube carcinoma (1 patient), uterine sarcoma (1 patient), or rectal carcinoma (1 patient) were reviewed. The histology of the 96 primary bladder tumors was 81 transitional cell carcinomas (TCC), 8 adenocarcinomas, 5 squamous cell carcinomas, 1 small cell carcinoma, and 1 unclassified. Follow-up ranged from 1.5-100 months (mean, 26 mos; median, 24 mos). In all patients, the bladder neck and up to 1 cm in length of the adjacent urethra were removed with the bladder. An ileal orthotopic neobladder procedure was performed if staging biopsies of the bladder neck and intraoperative frozen section of the urethral margin revealed no tumor. RESULTS: There was no perioperative mortality, and an early and late complication rate requiring secondary intervention in 5 (5%) and 12 (12%) patients. With 88 of 102 patients alive and 83 of 102 patients disease free, a disease-specific survival of 74% and a disease-free survival of 63% was estimated at 5 years. No pelvic recurrence was seen in 81 patients with TCC. Three pelvic recurrences occurred, two tumors of the inner genitalia and one adenocarcinoma of the bladder, none of them in the area of the urethra or its supplying autonomic nerves. Daytime continence was 82%; nocturnal continence was 72%. Twelve (12%) patients were unable to empty their bladders completely and needed some form of catheterization. CONCLUSIONS: The functional and oncologic outcome of female patients with an orthotopic urinary diversion to a remnant urethra was found to be comparable to that found in large studies on males. An orthotopic neobladder proved to be an oncologically safe option for women with pelvic tumors and was found to provide quality of life when there was adherence to previously defined selection criteria.

A randomized, prospective trial of central venous ports connected to standard open-ended or Groshong catheters in adult oncology patients.

BACKGROUND: Implanted central venous access is practiced extensively in oncology; however, information on the relevance of using the device with a valved catheter (Groshong), compared with an open-ended catheter, is scarce. The authors investigated the two types of catheters in a randomized trial using the same type of subcutaneous port and evaluated efficacy as well as early and late complications. METHODS: Three hundred four patients with malignant disease (solid tumors) who were eligible to receive intravenous chemotherapy were accrued during a 15-month period. After providing informed consent, the patients were assigned randomly to implantation of a titanium and silicone, rubber port (Dome Port; Bard Inc., Salt Lake City, UT) attached either to an 8.0-F silastic Groshongtrade mark catheter tube (experimental group) or to a 9.6-F silastic open-ended catheter tube (control group). Both catheters were manufactured by Bard Inc. Implantation, care, and follow-up followed the same protocol guidelines until removal of the device, death, or ending of the study. Power and color Doppler ultrasound examinations of internal jugular and subclavian veins were performed at 1 month and at 4 months or at anytime when a venous thrombosis was suspected. RESULTS: Three hundred two patients (99.3%) were evaluable, 150 patients in the control group and 152 in the experimental group. The median follow-up was 237 days. There was a trend toward more early complications in the experimental group (5.9%; 95% confidence interval [95% CI], 2.7-10.9%) than in the control group (2.7%; 95% CI, 0.7-6.7%), although the difference was not statistically significant (P = 0.26). There was also a trend toward more late complications in the experimental group (17.1%; 95% CI, 11.5-24.1%) compared with the control group (10.7%; 95% CI, 6.2-16.7%; P = 0.13), although the difference, again, was not statistically significant. The most frequent late complication was the inability to draw blood samples (12.5% in the experimental group and 2% in the control group; P < 0.001). Sepsis was observed in 1 patient and in 3 patients and venous thrombosis was observed in 6 patients and in 11 patients in the experimental and control treatment groups, respectively (P value not significant). CONCLUSIONS: In the tested clinical setting, the use of a Groshong catheter was not superior to a traditional, open-ended device in terms of early and late complications of the implant and its use. The theoretical justification for its superiority for more efficient use of the implantable device could not be substantiated.

[Erectile dysfunction: prevalence and effect on the quality of life; Boxmeer study].

OBJECTIVE: To assess the prevalence of erectile dysfunction (ED), and its influence on both the quality of life, and health care seeking behaviour. METHOD: An age-stratified random sample was drawn from men aged 40-79 years in Boxmeer, the Netherlands (n = 1771), together with their partners. A questionnaire was mailed to the study population to collect data on ED, and the quality of life, both general and disorder related. The prevalence of ED was measured with the direct question 'Do you have problems getting an erection?'. The influence of ED on sexual function was measured with the Dutch version of the Sexual Function Inventory questionnaire. RESULTS: Seventy percent of all men (n = 1233) and 73% of their partners (n = 1071) responded to the questionnaire. The prevalence of ED increased with age class. To the question regarding problems to get an erection, 13% (95% confidence interval: 11-15%) of all men answered affirmatively (40-49 years: 6%; 50-59: 9%; 60-69: 22%; 70-79: 38%). All men aged 40-49 years of age with ED and 16% of men aged 70-79 with ED considered their ED as bothersome. Amongst 40 to 49 year old men with ED, 64% considered their ED as a big or rather a big problem. Amongst older men this percentage was much smaller: 50-59 years: 38%; 60-69: 37%, and 70-79: 27%. Thirty-four percent of all men with ED and 16% of their spouses were dissatisfied with their sex life. Twenty-five percent of men with ED consulted a doctor, with a mean delay of 13 months. ED bore a strong correlation with the general quality of life and comorbidity. CONCLUSION: ED was a common disorder within the population. Its prevalence was higher among older age groups, but they regarded ED as less of a problem than the younger age groups. Only a quarter of all men with ED consulted a physician.

Prostate cancer mortality after introduction of prostate-specific antigen mass screening in the Federal State of Tyrol, Austria.

OBJECTIVES: To monitor the impact of screening in a natural experiment by comparing prostate cancer mortality in Tyrol, where prostate-specific antigen (PSA) testing was introduced at no charge, with the rest of Austria, where it was not introduced. METHODS: In 1993, PSA testing was made freely available to men aged 45 to 75 years in the Federal State of Tyrol, Austria. At least two thirds of all men in this age range have been tested at least once during the first 5 years of the study. Initially, only total PSA was measured, but free PSA measurement was added in 1995. The IMX assay was used. Digital rectal examination was not part of the screening examination. RESULTS: Significant migration to lower stages has been observed since the introduction of this screening program. A reduction in mortality rates in the rest of Austria from 1993 onward has occurred, with the reduction in Tyrol much greater; the mortality remained fairly constant between 1993 and 1995 and subsequently fell. The trends in prostate cancer mortality rates since 1993 differ significantly between Tyrol (P = 0.006) and the rest of Austria. On the basis of the age-specific death rates averaged from 1986 to 1990, the difference between the number of expected and observed deaths from prostate cancer in Tyrol was 22 in the group aged 40 to 79 years in 1998 and 18 the following year. CONCLUSIONS: These findings are consistent with the hypothesis that the policy of making PSA testing freely available, and the wide acceptance by men in the population, is associated with a reduction in prostate cancer mortality in an area in which urology services and radiotherapy are available freely to all patients. It is our opinion that most of this decline is likely to be due to aggressive downstaging and successful treatment and that any contribution from detecting and treating early cancers will only become apparent in the years to come.

Meta-analysis of randomized trials of terazosin in the treatment of benign prostatic hyperplasia.

OBJECTIVES: To determine the effectiveness of the long-acting alpha(1)-adrenergic receptor blocking agent terazosin compared with placebo on lower urinary tract symptoms and peak urinary flow rate in men with clinical benign prostatic hyperplasia. METHODS: A formal meta-analysis of all nine randomized trials of terazosin using both an Empirical Bayes and a fully Bayesian approach was conducted. A pooled analysis was conducted on those studies in which patients had a baseline assessment of prostate volume by transrectal ultrasonography. RESULTS: No evidence of heterogeneity was found in the estimated effects of terazosin on the change in peak flow rates in the studies. Terazosin treatment was associated with an increase in the peak flow rate of 1.4 mL/s (95% confidence interval [1.0, 1.7]) compared with placebo. Terazosin resulted in an average reduction of 2.2 points over placebo (95% confidence interval [1.6, 3.0]) regarding the common symptom score (range 0 to 36 points). A mild heterogeneity was found across the studies, with the decrease in symptom score slightly greater with longer treatment duration. No evidence was found that the baseline prostate volume influenced the effect of terazosin. CONCLUSIONS: Terazosin was effective and superior to placebo in reducing symptoms and increasing the peak urinary flow rate. The effect of terazosin on the peak urinary flow rate was apparent in studies as short as 8 weeks. Most importantly, the effect of terazosin on symptoms and peak urinary flow rate was independent of the baseline prostate size for the range of prostate volumes reported.

Measures of attention and hyperactivity symptoms in a high-risk sample of children of bipolar parents.

BACKGROUND: To determine whether significant symptoms of inattention were present among the offspring of well-characterized bipolar parents. METHODS: We included 53 offspring of 30 parents meeting DSM-IV criteria for bipolar disorder diagnosed by consensus on the basis of a SADS-L interview and a wealth of longitudinal clinical data. The unaffected parent had no lifetime history of a major psychiatric illness. Offspring, prospectively followed for up to 5 years, completed psychometric measures of attention and mood when judged to be at a good level of functioning (well, remitted or treated). RESULTS: Those offspring with any lifetime psychiatric diagnosis endorsed more subjective problems with attention. However, there was no measurable difference on tasks of sustained attention between those with and those without a lifetime psychiatric illness including affective disorder. There was a significant association between self-reported symptoms of depression and inattention, but no association between either self-report measure and an objective measure of sustained attention. LIMITATIONS: This study was not intended to be a comprehensive neuropsychological investigation of at risk offspring. CONCLUSIONS: In this high-risk population, subjective difficulty with attention appeared to be state-dependent, associated with the degree of subjective distress related to an underlying psychiatric illness.
