Bicalutamide (Casodex) 150 mg plus standard care in early non-metastatic prostate cancer: results from Early Prostate Cancer Trial 24 at a median 7 years' follow-up.

Trial 24, one of three ongoing trials in the Early Prostate Cancer programme, is evaluating the efficacy and tolerability of bicalutamide (Casodex) 150 mg following standard care (radiotherapy, radical prostatectomy or watchful waiting) in patients with early, non-metastatic prostate cancer. At 7 years' median follow-up, addition of bicalutamide significantly improved objective progression-free survival (PFS) for patients with locally advanced disease, reducing the risk of progression by 34% versus standard care alone (hazard ratio 0.66; 95% confidence interval 0.55, 0.79; P<0.001). In localized disease, a significant difference in objective PFS was not found. There was no significant difference in overall survival.

Large renal angiomyolipomas: digital subtraction angiographic grading and presentation with bleeding.

AIM: To investigate whether a grading system of renal AMLs based on digital subtraction angiography (DSA) and computerized tomography (CT), could help to select patients for embolization. MATERIALS AND METHODS: Thirty patients with 35 renal angiomyolipomas (size range 4-20 cm, mean 9.9 cm) underwent both digital subtraction angiography (DSA) and computed tomography (CT). Based on the DSA appearance the tumours were graded into three grades: grade I, minimal vascularity; grade II, moderate vascularity; grade III, marked vascularity. RESULTS: There were seven grade I (mean 9.3 cm, range 4.5-20 cm), 18 grade II (mean 8.9 cm, range 5-18 cm) and 10 grade III tumours (mean 12.1 cm, range 4-20 cm). Five grade I tumours did not cause symptoms (71%) and two caused flank pain and haematuria, respectively (14.3% each). Nine of the grade II tumours were asymptomatic (50%), seven caused bleeding (39%) and two caused flank pain (11%). Four grade III tumours were asymptomatic (40%), five caused bleeding (50%) and one pain (10%). CONCLUSIONS: According to our criteria, large angiomyolipomas with minimal vascularity are less likely to bleed, and do not need prophylactic treatment. This needs to be confirmed in larger studies.

Expression of cyclooxygenase-2 in Wilms tumor: immunohistochemical study using tissue microarray methodology.

PURPOSE: Cyclooxygenase-2, a key enzyme in prostaglandin biosynthesis, has been shown to be involved in the modulation of cell growth, inflammation and apoptosis. Its involvement in the development of several human neoplasms has also been documented as well as the significant antitumor effects of its inhibitors. To our knowledge cyclooxygenase-2 expression in Wilms tumor has not been studied. MATERIALS AND METHODS: A tissue microarray multitissue block was prepared from 14 samples of Wilms tumor, each from a different patient, from xenografts derived thereof, and from normal human lung, liver, renal cortex and medulla tissues as controls. Each sample was represented in the block by 3 or 4 cores 0.6 mm in diameter. After serial slicing to 4 mum the histological slides were stained with hematoxylin and eosin, and immunostained with anti-cyclooxygenase-2 antibodies. Immunostaining was graded semiquantitatively according to the percent of stained cells with the cytoplasmic pattern of staining and according to staining intensity. RESULTS: All authentic human pathological samples except 1 anaplastic Wilms tumor as well as Wilms tumor xenografts expressed cyclooxygenase-2 in all Wilms tumor cellular components except the stroma. Expression was also observed in Wilms tumor lung metastasis and in tumors that overgrew chemotherapy. In comparison, cyclooxygenase-2 expression in normal kidneys was less prominent than in Wilms tumor samples and it was confined to the tubular epithelium in the cortex and medulla. CONCLUSIONS: Cyclooxygenase-2 expression is characteristic of all nonanaplastic Wilms tumors at all stages. It is similar to the previously observed pan-expression of ErbB2 receptors in these tumors. The potential therapeutic role of cyclooxygenase-2 inhibitors should be evaluated for Wilms tumor.

Testicular fixation following torsion of the spermatic cord--does it guarantee prevention of recurrent torsion events?

PURPOSE: Patients with history of testicular torsion who have undergone orchiopexy may rarely present with acute scrotum due to recurrent episodes of torsion. Most of the reports in the literature regarding this scenario refer to the era when absorbable sutures were used for testicular fixation. Herein, we review our experience in recent years, focusing upon the surgical technique and sutures' material. MATERIALS AND METHODS: Between 1991 and 2003, 179 patients were operated on at our institute with the clinical diagnosis of unilateral testicular torsion. They ranged in age between neonates to 45 years old (average age 18). In a comprehensive retrospective study we managed to locate 8 patients who experienced recurrent intravaginal testicular torsion following previous fixation performed in our institute. RESULTS: The patients who experienced repeat torsion have initially presented at the mean age of 18.5 years old (range 12 to 30) with unilateral twisted testicle (left 3, right 5). Urgent explorations were generally performed, apart from in 2 cases that underwent spontaneous detorsion which was followed by an elective surgery. Testicular fixation was conducted by suturing of the tunica albuginea to the dartos layer by 2 sutures at each side, using chromic 3-zero in the 3 more early cases, followed by the usage of polyglactin 3-zero stitches in 4 subsequent cases and 3 sutures of polypropylene 4-zero for each testicle, thereafter, in the most recent case. The patients presented with repeat torsion, 0.5 to 23 years subsequently (average 7 years), involving either the ipsilateral testicle in 4 cases or the contralateral gonad in 4. CONCLUSIONS: Recurrent torsion following previous testicular fixation may appear many years following the primary procedure, even in cases in which either polyglactin or, notwithstanding, polypropylene sutures have been applied, in accordance with the common practice used in the last 2 decades. Increased awareness regarding this possibility is imperative for early diagnosis and prevention of testicular loss.

Orthopaedic shoes improve gait in a Charcot-Marie-Tooth patient: a combined clinical and quantified case study.

The aim of this study was to assess the extent to which orthopaedic shoes improved gait in a patient with Charcot-Marie-Tooth (CMT) disease and to show how the latest gait analysis tools available can help to assess and quantify the efficacy of this treatment. The case of a 55-year-old woman with CMT disease is described. She complained mainly of pain and frequent falling. The physical examination and the clinical gait analysis showed the presence of bilateral foot drop, high-stepping and varus. Treatment based on physical therapy and orthopaedic shoes was prescribed. In order to assess the clinical efficacy of the treatment, a complete physical examination was carried out after the patient had been wearing the orthopaedic shoes for one month. The quantified assessment was performed with a Gaitrite system, which can be used to record the spatio-temporal parameters of gait. It was concluded that orthopaedic shoes provide specialists in physical and rehabilitation medicine with an excellent means of treating gait disabilities in patients with CMT disease. With the made-to-measure orthopaedic shoes used, the falling and pain disappeared; the patient's walking speed increased and the foot support base decreased in size. Both the clinical and quantified data confirmed the subjective improvement perceived by the patient. The latest tools available for performing quantified gait analysis in clinical practice provide useful means of objectively assessing the success of treatment.

Crossbreeding parameter estimation for functional longevity in rabbits using survival analysis methodology.

A complete diallel cross involving 3 maternal lines of rabbit was performed to estimate cross-breeding parameters for functional longevity. This trait was defined as the ability to delay involuntary culling. The lines considered, A, V, and Prat, had all been selected by litter size at weaning for a long period. Data were related to a total of 653 does belonging to the 9 genetic types from the diallel cross; does were reared and bred on the same commercial farm. Survival analysis was performed using a Cox proportional hazard model. The model incorporated time-dependent factors, such as year-season, litter size, and the interaction between cycle and physiological status of the female; time-independent factors, such as the genetic type of the doe; and sire and dam random factors. Crossbreeding parameters were estimated from the solutions obtained for the type of doe and its estimated variance-covariance matrix, using a generalized least squares procedure. The estimated parameters were the differences between lines in direct genetic effects and maternal genetic effects and individual heterosis. Relevant differences were observed in direct genetic effects between lines A and Prat but not in any maternal effects. Heterosis was found to be significant and favorable between lines A and Prat, and between the lines V and Prat. The magnitude of this effect was variable but important, especially in the first cross. Results stress the importance of using crosses between specialized lines to produce does for intensive meat rabbit production.

Genetics of litter size in three maternal lines of rabbits: repeatability versus multiple-trait models.

Variance components were estimated in 3 lines of rabbits selected for litter size at weaning (A, Prat, and V) to test one of the assumptions of the models used for selection: that litter size data at different parities are repeated measurements of the same trait. Multiple-trait analyses were performed for the total number of kits born (TB), the number of kits born alive (BA), and the number of kits weaned (NW) per litter. Estimates were obtained by REML in multivariate analyses, including all of the information of the selection criteria, under a repeatability model or a multiple-trait model, considering litter size at the first, second, and subsequent parities as different traits. Models included the fixed effects of the physiological status of the female and the year-season of mating day, buck and doe random permanent environmental effects, and doe additive genetic effects. Results indicated that prolificacy was determined mainly by doe components and that the service sire had a very small effect. Heritabilities for the first and second parities were greater than the estimates obtained under the repeatability model (0.04 to 0.14 for the repeatability model). In the A and V lines, similar values of heritability were found at the first and second parities, but in the Prat line heritability at the second parity was always greater than at the first and greater parities (values of 0.21, 0.17, and 0.15 for TB, BA, and NW, respectively, in second parities of the Prat line). Genetic correlations between the same traits at different parities were approximately 0.8 for all traits in line A, but much lower in the other 2 lines. On average, the values were 0.64 for TB, 0.48 for BA, and 0.39 for NW between the first and second parities, and 0.65 for TB, 0.56 for BA, and 0.45 for NW between the first and third and greater parities. Genetic correlations between the second and greater parities showed the greatest values (approximately 0.8) in lines A and Prat for all traits, but they were lower in line V (0.63 for BA and 0.37 for NW). The heterogeneity of heritabilities and genetic correlations between parities lower than 0.9 suggests that litter size at different parities could be considered as different traits when genetic evaluations are performed. However, when the accuracies of predicted breeding values under a multiple-trait and a repeatability model were calculated, assuming the first to be the true model, the values obtained were nearly the same for all traits in all lines.

Survival analysis in two lines of rabbits selected for reproductive traits.

The objective of the study was to analyze the reproductive longevity of 2 selected lines of rabbits. The first one was the Prat line, a line selected in Spain on litter size at weaning, and raised in overlapping generations. The second one was a French line, the A1077 line, selected on litter size at birth and individual weight at 63 d of age, managed in batches, and artificially inseminated with discrete generations. Reproductive longevity was measured beginning at the first successful mating, assessed by a pregnancy diagnosis in the Prat line, and at the first kindling in the A1077 line. In the A1077 line, culling for infertility occurred after 3 unsuccessful artificial inseminations. The trait analyzed, defined as the doe length of productive life (LPL), was the time in days between date of the first positive pregnancy diagnosis and date of culling or death in the Prat line. In the A1077 line, the trait was the number of AI after the first kindling. Effects included in the model were year-season, litter size at birth, reproductive cycle or physiological status x cycle interaction, age at first mating, batch (only for the A1077 line), and additive genetic value of the animal as a random effect. Survival analyses were carried out with a Cox model for the Prat line and a discrete model for the A1077 line. The estimated heritability values for LPL were around 0.16 in the Prat and A1077 lines with a model including physiological status x cycle interaction effect. Removing this effect from the model led to an increase in estimated genetic variance with h2 = 0.24 and 0.19 in the Prat and A1077 lines, respectively. Including the traits LPL and number of AI from first fertile mating or AI in selection programs could increase reproductive longevity and decrease the replacement rate.

Variability, repeatability and phenotypic relationships of several characteristics of production and semen quality in rabbit.

A total of 2140 ejaculates from 156 adult males pertaining to four groups of bucks were analysed and the following traits were recorded: pH, ejaculate volume (V), mass motility (Mm), individual motility (Mi), concentration (Cn), total number of spermatozoa per ejaculate (TSE), percentage of sperm viability (Vi), percentage of sperm with acrosome integrity (NAR), percentage of sperm normalcy (Nr), percentage of sperm morphological abnormalities of head (H), neck-midpiece (Nm) and tail (T) and presence of proximal and distal cytoplasmic droplet (Dp, Dd). Principal component (PC) analysis and phenotypic correlations were performed in order to examine the relationships between qualitative and quantitative traits of rabbit semen. The repeatability of the traits measured was also estimated. Phenotypic correlations between sperm traits were estimated as the residual correlation from an analysis of variance, including the effects of: genetic type of the male, order of the ejaculate, day of collection and the permanent non-additive random effect of the male to which the observation corresponds. The repeatability of these traits was analysed separately, in a set of univariate analyses, using VCE software. The previously defined mixed model was used for this analysis. The principal component analysis was performed using the Princomp procedure of the SAS v.8 package. The first four PC explained 62% of total variation: 23%, 18%, 12% and 8%, respectively. Percentage of sperm viability, NAR, Nr, T and Nm were the predominant variables in the first PC. Mass motility, Mi, pH, Cn and TSE were located in the second. Percentage of sperm with the presence of proximal and distal cytoplasmic droplet, NAR, Vi and Nr were the predominant traits in the third and V defined the fourth. Repeatability of semen quality traits was moderate for most of the traits. The highest values (about 0.45) corresponded to V, Cn, Nr and Dp and the lowest (about 0.10) to H and Nm. Repeatability of the first ejaculate was greater than that of the second for pH, Mm, Mi, H, Dp and Dd.

Bicalutamide ('Casodex') 150 mg in addition to standard care in patients with nonmetastatic prostate cancer: updated results from a randomised double-blind phase III study (median follow-up 5.1 y) in the early prostate cancer programme.

Trial 24 is one of three placebo-controlled trials within the ongoing bicalutamide ('Casodex') Early Prostate Cancer (EPC) programme evaluating bicalutamide 150 mg/day in addition to radical prostatectomy, radiotherapy or watchful waiting for T1b-4, any N, M0 prostate cancer. In Trial 24, at 5.1 y median follow-up, the addition of bicalutamide significantly (P < 0.0001) improved objective progression-free survival (PFS) and prostate-specific antigen PFS compared with standard care alone. There was no significant difference in overall survival (P = 0.746). In the context of the whole EPC programme, long-term bicalutamide is not appropriate for localised disease, yet provides advantages in delaying disease progression in patients with locally advanced prostate cancer.

Genetic parameters of fertility in two lines of rabbits with different reproductive potential.

A Bayesian analysis with a threshold model was performed for fertility defined as a binary trait (1 = successful mating, 0 = unsuccessful mating) in two populations of rabbits of different reproductive potential and different genetic origin: Line P selected for litter size and Line C selected for growth rate. There were 20,793 records of natural mating (86.2% successful) in Line C between 1983 and 2003, and 17,548 records (80.5% successful) in Line P, between 1992 and 2003. Data related to 5,388 and 3,848 females and 1,021 and 685 males in Lines C and P, respectively. The pedigree included 6,409 and 4,533 individuals in Lines C and P, respectively. The binary response was modeled under a probit approach. The model for the latent variable included male and female additive genetic effects, male and female permanent environmental effects, and the year-season and physiological status of the female (nulliparous, multiparous lactating, or multiparous nonlactating) as systematic effects. Means (standard deviation in parentheses) of the estimated marginal posterior distribution (EMPD) of male heritability were 0.013 (0.006) and 0.010 (0.008) in Lines C and P, respectively, and those of EMPD of female heritability were 0.056 (0.013) and 0.062 (0.018) in Lines C and P, respectively. Means of the EMPD of the proportion of the phenotypic variance due to environmental male and female effects were, respectively, 0.031 (0.007) and 0.128 (0.018) in Line C and 0.053 (0.010) and 0.231 (0.024) in Line P. Means (standard deviations in parentheses) of the EMPD of genetic correlation between male and female fertility were 0.733 (0.197) in Line C and 0.434 (0.381) in Line P. The posterior distribution of genetic correlations presents a huge dispersion, and the estimates should be taken with caution because of the almost negligible estimate of the male genetic component. Results indicate that little genetic variation exists for female fertility, and practically none for male fertility. It would, therefore, be possible to improve reproductive performance by including female fertility in a breeding program, but response to selection would be very small.

ErbB2 is a tumor associated antigen and a suitable therapeutic target in Wilms tumor.

PURPOSE: The modern multimodality therapeutic approach to Wilms tumor (WT), combining surgery with radiotherapy and chemotherapy results in high cure rates even for high stage disease. However, the combination of radiotherapy and chemotherapy is associated with severe early and late complications such as neutropenic sepsis, growth retardation and secondary malignancies. Therefore, novel therapeutic strategies, which would decrease the treatment burden, are required. We studied the expression of erbB2 growth factor receptor in WT cells as well as its role as a tumor therapeutic target in an in vivo xenograft model of Wilms tumor. MATERIALS AND METHODS: Paraffin embedded pathological samples from 14 different WT cases as well as xenografts derived thereof were immunostained with anti-erbB2 monoclonal antibody. The immunostaining was graded in comparison to a known positive control (breast cancer) and was scored by the intensity of staining (0 to +3) multiplied by the percentage of cells expressing the antigen. The expression of erbB2 in the human WT xenograft was verified also by fluorescence activated cell sorter analysis. In addition, nude mice bearing established subcutaneous human WT xenografts were treated with either 3 intraperitoneal injections of N29 anti-erbB2 monoclonal antibody or irrelevant antibody. RESULTS: All of the authentic human pathological samples, except 1 anaplastic WT as well the WT xenografts (at different stages), expressed erbB2. Expression was also observed in WT metastasis and in tumors which out grew chemotherapy. Systemic administration of anti-erbB2 monoclonal antibody inhibited and even prevented the growth of WT xenograft in vivo. CONCLUSIONS: ErbB2 is a tumor associated antigen in WT. Being expressed in almost all tumor stages, our in vivo model suggests that erbB2 may serve as a WT therapeutic target. Further work is needed to establish the role of erbB2 in the disease and its potential use in decreasing current treatment burden.

Elliptical selection experiment for the estimation of genetic parameters of the growth rate and feed conversion ratio in rabbits.

Two elliptical selection experiments were performed in two contemporary sire lines of rabbits (C and R) in order to optimize the experimental design for estimating the genetic parameters of the growth rate (GR) and feed conversion ratio (FCR). Twelve males and 19 females from line C, and 13 males and 23 females from line R, were selected from an ellipse defined by a quadratic index based on these traits. Data from 160 rabbits of each of the parental generations of lines C and R and their offspring (275 and 266 animals, respectively) were used for the analysis. A Bayesian framework was adopted for inference. Marginal posterior distributions of the genetic parameters were obtained by Gibbs sampling. An animal model including batch, parity order, litter size, and common environmental litter effects was assumed. Posterior means (posterior standard deviations) for heritabilities of GR and FCR were estimated to be 0.31 (0.10) and 0.31 (0.10), respectively, in line C and 0.21 (0.08) and 0.25 (0.12) in line R. Posterior means of the proportion of the variance due to common litter environmental effects were 0.14 (0.06) and 0.21 (0.06) for GR and FCR, respectively, in line C and 0.17 (0.06) and 0.22 (0.06) in line R. Posterior means of genetic correlation between both traits were -0.49 (0.25) in line C and -0.47 (0.32) in line R, indicating that selection for GR was expected to result in a similar correlated response in FCR in both lines.

Analysis of the long-term outcome of surgically corrected vesico-ureteric reflux.

OBJECTIVE: To review patients who had vesico-ureteric reflux corrected surgically by ureteric reimplantation during childhood, and thus assess their long-term outcome. PATIENTS AND METHODS: Between 1970 and 1979, 322 children underwent ureteric reimplantation; 100 (79 women and 21 men) were re-assessed and the long-term results evaluated using a questionnaire, a review of the patients' current medical records and an appointment in the outpatient clinic. The evaluation focused on the frequency of late urinary tract infections (UTIs), current renal function tests, related complications during pregnancy and the incidence of hypertension at least 20 years after surgery. RESULTS: Of the study group, 51% (66% of men and 47% of women) had no long-term urological complications. The incidence of UTIs was 43% in women and 24% in men, and of pyelonephritis 27% and 9.5%, respectively. Hypertension was detected in 6% of the patients during assessment. There were new renal scars, despite surgery, in 20% of the patients. Forty-seven women had been pregnant, 28% reporting UTIs during pregnancy. In 7% of 94 pregnancies the women also had pre-eclampsia and two women had transient gestational ureteric obstruction which required drainage. Renal functional tests were worse in one man and one woman who developed end-stage renal disease and had a renal transplant. CONCLUSIONS: This series shows that even patients who were treated successfully by ureteric reimplantation during childhood are prone to recurrent UTIs, progressive renal scarring, hypertension and complications during pregnancy. There is a need to establish a protocol for the long-term follow-up of such patients.

[Schizophrenic patients living in the community. Nursing referral].

The authors describe the clinical and socio-demograpaphic characteristics of schizophrenic patients who live out in the community. The authors study the clinical profile and the disabilities of those items derived from nursing. To do so, the authors made a random selection from persons diagnosed as schizophrenics who visited one of the five Mental Health Centers in the Sant Joan de Déu Hospital network's Mental Health Services. The authors evaluated sociodemographic characteristics, use of services, disabilities based on WHO-DAS, PANSS psychopathology, and LSP ability to function socially. Of the 231 patients included in this study group, 141 patients followed a psychiatrist only treatment program while 90, or 39%, followed a combined psychiatrist-nurse treatment program. Upon comparing these two groups, the authors observed that those patients who followed a combined treatment program had a higher score on the Negative PANSS test (*p < 0.005) which means they have many more difficulties to adequately carry out social functions in daily life activities. On the other hand, this group had lower scores on the WHO-DAS-IV Total test (*p < 0.001), on the WHO-DAS-IV Occupational Test (*p < 0.001), on the WHO-DAS-IV Familiar Test (*p < 0.005) and on WHO-DAS-IV Personal Care Test (*p < 0.005). The authors did not observe any significant results on the rest of the subscales nor on the LSP test.

Transepithelial intestinal excretion of ciprofloxacin in humans.

The excretion of ciprofloxacin in the small bowel was studied in 40 patients undergoing bowel surgery. Ciprofloxacin (200 mg) was administered iv, and intestinal samples were collected over a 120-min period. In ileal loops ciprofloxacin concentrations reached a peak of 4.0 mg/L, whereas in caecal fluid samples, concentrations were < 0.16 mg/L. Ciprofloxacin administered directly into the ileal and caecal loops did not result in measurable blood levels for 2 h. The results confirm that ciprofloxacin is selectively excreted into the small bowel.

Management of urethral erosion caused by a pubovaginal fascial sling.

Urethral erosion by a fascial sling is a rare postoperative complication, and its repair can become a major surgical endeavor. We present a case of autologous fascial sling erosion into the mid-urethra in a 46-year-old woman that was diagnosed after traumatic urethral catheterization. After 3 months of conservative management failed, we released the sling tension surgically by bilateral excision of the graft, leaving the midline structures undisturbed. This allowed resumption of normal voiding, with complete long-term symptomatic relief.

Routine cystoscopy before radical prostatectomy: is it justified?

OBJECTIVES: The extent of the required preoperative workup of patients who are candidates for radical prostatectomy is still controversial. Traditionally, cystoscopy has been reserved only for those patients who present with hematuria. However, several investigators have reported significant incidental cystoscopic findings among these patients and advocated the routine use of cystoscopy before radical prostatectomy. In view of the conflicting recommendations, we elected to assess the role of routine cystoscopy in a series of patients with prostate cancer at our institute. METHODS: We retrospectively reviewed the cystoscopic findings of 225 consecutive patients with organ-confined prostate carcinoma scheduled for radical prostatectomy. Rigid cystoscopy was performed before surgery either in an outpatient setting or on the operating table just before the operation. RESULTS: Significant cystoscopic findings were noted in 3 (1.3%) of 225 patients. These included a bladder stone in 1 patient, superficial bladder tumor in 1 patient, and a post-sphincteric urethral polyp containing prostatic adenocarcinoma in a third patient. This polyp was resected transurethrally and the patient was treated thereafter with irradiation because of local extension. None of the 3 patients had microscopic hematuria on urinalysis to suggest the findings. Cystoscopy was uneventful in all patients, apart from occasional mild hematuria. CONCLUSIONS: These results show that the treatment of patients who were candidates for radical prostatectomy was affected by the findings of preoperative cystoscopy in less than 1% of the cases. We believe that in view of the low yield of cystoscopic findings in these patients, in an era in which cost effectiveness is a major issue, the routine use of cystoscopy before radical prostatectomy is not justified.
