Adenocarcinoma of the uterine cervix compared with squamous cell carcinoma: a 12-year study in Southampton and South-west Hampshire.

In a 12-year study of the population of Southampton and South-west Hampshire (SSWH), there was no rise or fall in the incidence of adenocarcinoma of the uterine cervix, although the incidence of squamous cell carcinoma fell from 14 to 7.2 per 100000 women years and the overall fall in age-adjusted incidence of cervical carcinoma was commensurate with that of England and Wales. The majority (59%) of adenocarcinomas were seen in women aged less than 50, supporting the concept of a higher risk in young women. Screen-detected carcinomas accounted for 50% of adenocarcinomas and 41% of squamous cell carcinomas in women aged 20-64 (the difference was not significant). There were more screen-detected adenocarcinomas of less than 3 mm depth of invasion and 7 mm lateral extension during the third period of the study (1991-1993). The results are consistent with reports of an increased risk of cervical cancer in women born since 1940, and lesser effectiveness of screening in preventing adenocarcinoma compared with squamous cell carcinoma. High prevalence of early screen-detected carcinomas may have been a factor in recent reports of increased incidence of adenocarcinoma.

Needs of carers of severely disabled people: are they identified and met adequately?

OBJECTIVE: To examine the unmet needs of informal carers of community dwelling disabled people and to compare their perspectives to those of disabled people and nominated professionals. It was hypothesised that a poor recognition of carers' needs could have implications for carers' well- being and thus their ability to maintain their caring role. Need was defined as a service or a resource that would confer a health or rehabilitation gain. DESIGN: Face to face interviews with carers and disabled participants, telephone interviews with professionals (Southern England). Disabled participants had been selected randomly from two disability registers. MAIN OUTCOME MEASURES: The Southampton Needs Assessment Questionnaire (carers version), SF-36 (carers' health status). RESULTS: Carers experienced similar health status to people in the general population. The most frequently carer-reported unmet needs were for short breaks, domestic help and respite care. Carers who had reported unmet need for short breaks had significantly poorer levels of mental health and vitality (SF-36) than carers who had not reported this. Similar numbers of unmet carers' needs were reported by disabled participants, professionals and carers themselves. In terms of type of unmet needs, poor concordance between carers and disabled participants occurred in 52% of cases: carers reported more unmet needs than disabled participants for short breaks and domestic help. Poor concordance scores between carers and professionals occurred in 59% of cases: carers reported more unmet needs for short breaks than professionals and professionals reported more unmet needs for formal respite care. CONCLUSION: In line with recent legislation, carers' needs must be independently addressed and services, especially for flexible community support such as short break services, must be developed specifically to meet the needs of carers. Further research is warranted to evaluate whether recent legislation for carers has any effect on carers' well-being and ability to cope with their caring role.

Towards a Statewide Cardiac Surgery Database: the Victorian initiative.

The establishment of the Australasian Society of Cardiac and Thoracic Surgeons (ASCTS) at the beginning of the 1990s gave rise to an early proposal for the development of a cardiac surgical database. The Victorian Government gave its in-principle backing to a statewide database project from late 1997. Release of a promised dollar 200,000 grant for development was contingent on the ASCTS being able to fulfil several initial requirements. These were: (i) the provision of an indicative annual report outlining performance against a series of clinical indicators; (ii) an indicative peer-review process; and (iii) the addressing of issues surrounding intellectual property and ownership of any database that was developed. In outlining a strategy to be used in developing and implementing the project plan, it was determined by the project development team that all Victorian cardiac surgical units were, in fact, collecting similar data, but were using different software and analytical tools. The Cardiovascular Disease Prevention Unit at the Baker Medical Research Institute in Melbourne has developed a model of mortality and risk-adjusted complications out of the pooled Victorian data. This, it is hoped, will be a forerunner of a major achievement in the monitoring of cardiac surgery procedures nationally, and the attainment of national and international best practice.

Developing performance indicators for cardiac surgery: a demonstration project in Victoria.

Six Victorian cardiac surgical units pooled data in order to undertake a demonstration project aimed at developing performance indicators to assess outcomes following cardiac surgery. The outcome of the project was an indicative report for the purpose of monitoring surgical performance indicators in a format suitable for: (i) the general public; (ii) the Victorian State Government; and (iii) the participating units and surgeons. Each participating cardiac surgical unit had an existing database used for recording information from each procedure. A request was made to each unit to extract a subset of data from all cases entered over the past 5 years. The proposed list of performance indicators included surgical mortality (within the period of admission for surgery), complication rates (including sternal infection, postoperative myocardial infarction, postoperative stroke, haemorrhage requiring return to theatre), and length of hospital stay. A model was developed from the data and used to provide risk-adjusted measures of hospital performance. Cases from five cardiac surgical units (n = 10 715) were included in the final analysis. A risk-adjusted model (including age, sex, diabetes, hypertension, smoking, procedure type, urgency of procedure) was developed for surgical mortality. Performance indicators for coronary artery bypass graft surgery, including mortality, sternal infection rate and length of hospital stay are presented. From the available data, performance indicators for cardiac surgery in Victorian hospitals compared favourably with international benchmarks. This project has demonstrated that prospective data collection using a standardised system could readily produce local risk-adjustment models for cardiac surgery to aid in developing appropriate performance indicators.

Intestinal disaccharidase deficiency without villous atrophy may represent early celiac disease.

BACKGROUND: Intestinal disaccharidase activities are decreased in untreated celiac disease and also in other conditions without villous atrophy. Of 908 patients examined for suspected malabsorption, 37 (4.1%) had generalized disaccharidase deficiency without villous atrophy. The aim was to determine if generalized disaccharidase deficiency without villous atrophy represented latent celiac disease. METHODS: Case notes and histology of the 37 patients were reviewed. History and blood investigations including antigliadin and endomysial antibodies were checked. Where celiac disease was suspected, endoscopic duodenal biopsies for histology and disaccharidase estimation were repeated. RESULTS: Of the initial 37 patients, 6 patients had had repeat endoscopic biopsies; one having celiac disease. A further 18 patients were reviewed. The remainder declined further investigation. Eight had repeat endoscopic duodenal biopsies; one had celiac disease. Two with positive celiac serology also had enteroscopy with jejunal biopsies; both had celiac disease. CONCLUSIONS: At least 11% of patients with generalized disaccharidase deficiency without villous atrophy develop celiac disease. Enteroscopic biopsies from distal duodenum and proximal jejunum should be considered as the next investigation if endomysial or antigliadin antibodies are positive.

Laser treatment for invasive and noninvasive carcinoma of the bladder.

Lasers are widely used in urologic surgery and have many well-developed applications. The use of lasers for the treatment of bladder cancer has been proven to be safe and minimally invasive. The neodymium:YAG laser is the most widely used instrument, although the holmium:YAG laser has also gained recent popularity. Noninvasive, small lesions are especially amenable to management with laser energy and have been treated with success rates that are at least as good as those of standard electrocautery resection. Complication rates are low. Laser therapy of invasive bladder cancer has significant limitations and should probably be restricted to stage T2 lesions.

Ratio of free-to-total prostate specific antigen correlates with tumor volume in patients with increased prostate specific antigen.

PURPOSE: We evaluated the relationship between the ratio of free-to-total prostate specific antigen (PSA) and prostate pathology, including grade, stage and tumor volume, among patients with prostate cancer who underwent radical prostatectomy. MATERIALS AND METHODS: We prospectively analyzed 54 consecutive patients with prostate cancer who underwent radical prostatectomy and in whom frozen serum was available for assessment of free-to-total PSA ratio. Pathological review was done with whole mount sections, and total tumor volume was determined by planimetry. Comparison between free-to-total PSA ratio and pathological parameters was performed using the Pearson correlation coefficient. RESULTS: Among the 54 patients mean total and free-to-total PSA ratio were 5.81 and 14.2 ng./ml., respectively, and free-to-total PSA ratio directly correlated with prostate volume (p = 0.037), and inversely correlated with Gleason score (p = 0.012) and extracapsular disease (p = 0.0074). Furthermore, there was a significant relationship between free-to-total PSA ratio and pathological stage pT2a/b in 39 cases versus pT3a/b in 15 (p = 0.005). Overall, there was no correlation between free-to-total PSA ratio and tumor volume. However, among 37 patients with an increased PSA, defined as greater than 4.0 ng./ml., a significant inverse relationship between free-to-total PSA ratio and tumor volume was identified (p = 0.01). Among this subset there was only a weak correlation with prostate volume (p = 0.049). CONCLUSIONS: Our findings suggest that free-to-total PSA ratio may be predictive of tumor biology among those patients with a total PSA of greater than 4 ng./ml. as evidenced by good correlation with tumor grade and volume. This finding appears to be independent of prostate volume. These preliminary results suggest the need for additional studies among patients with an increased PSA designed to evaluate the potential role of free-to-total PSA ratio in combination with traditional clinical variables in the prediction of prostate cancer pathology.

Common discriminative stimulus properties in rats of muscarinic antagonists, clozapine and the D3 preferring antagonist PNU-99194a: an analysis of possible mechanisms.

Dopamine D3 receptors have been implicated in the aetiology of schizophrenia and the actions of antipsychotic drugs. The initial studies reported here assessed the involvement of such receptors in the in vivo actions of the atypical antipsychotic clozapine and the putative D3-preferring antagonist PNU-99194A in drug discrimination assays. Rats trained to discriminate clozapine consistently generalized to PNU-99194A in two separate studies. However, four other putative D3-preferring antagonists (PD 152255, (+)-S14297, nafadotride and (+)-AJ 76) did not induce generalization to clozapine. In rats trained to discriminate PNU-99194A, which has been suggested to induce a stimulus mediated specifically by D3 antagonism, the D3-preferring antagonist (+)-UH 232 and clozapine both induced full generalization. However, the PNU-99194A-trained animals also generalized fully to the muscarinic antagonists scopolamine and trihexyphenidyl. A possible explanation for the symmetrical generalization observed between clozapine and PNU-99194A is that these drugs have common muscarinic antagonist actions, since muscarinic antagonists have been reported to substitute for clozapine in numerous prior studies. However, in vitro receptor binding studies with M1-M5 receptors indicated that (with the possible exception of the M4 receptor), no muscarinic receptor subtype had high affinity for both clozapine, PNU-99194A and scopolamine. In addition, other binding studies indicated that whereas clozapine and PNU-99194A had high affinity for the D3 receptor, scopolamine did not. It is therefore concluded that: (1) The generalization seen between clozapine, PNU-99194A and muscarinic antagonists may be mediated by common effects 'downstream' from either muscarinic or D3 receptors; (2) D3 antagonism does not play a critical role in the clozapine stimulus (since D3-preferring antagonists did not consistently induce generalization to clozapine); (3) although D3 antagonism plays a role in the PNU-91994A stimulus (since the D3-preferring antagonist (+)-UH 232 induced full generalization, in accord with results from prior studies with other D3-preferring antagonists, the PNU-99194A stimulus also has commonalities with that induced by muscarinic antagonists and clozapine. The in vivo differences observed between PNU-99194A and other D3-preferring antagonists should be borne in mind when this agent is used as a tool to study D3 receptor functioning in vivo. The similarities between the PNU-99194A and clozapine stimuli suggest tentatively that compounds with a profile like PNU-99194A may have antipsychotic actions similar to clozapine. Some preclinical data are suggestive of such effects of PNU-99194A.

Increased acid-sensing ion channel ASIC-3 in inflamed human intestine.

OBJECTIVES: Acid-sensing ion channels (ASICs) are expressed by rat sensory neurons and may mediate pain associated with tissue acidosis after inflammation or injury. Our aim was to examine the molecular forms and localization of ASICs in human intestine and dorsal root ganglia using immunochemical techniques, and to measure the effects of inflammation and injury. DESIGN AND METHODS: Inflamed Crohn's disease intestine and injured human dorsal root ganglia, with appropriate controls, were studied by Western blotting and immunohistochemistry, using specific affinity-purified ASIC antibodies. RESULTS: In the Western blot, there was a significant three-fold increase in the mean relative optical density of the ASIC-3 55-kDa band (but not ASIC-1 or ASIC-2) in full-thickness inflamed intestine, as well as in separated muscle and mucosal layers. There was a corresponding trend for an increased immunoreactive density and increased number of ASIC-3-positive neurons in the myenteric and sub-mucous plexus of inflamed intestine. In dorsal root ganglia, immunoreactivity for all ASICs was restricted to a sub-population (about 50%) of small-diameter (nociceptor) sensory neurons, and was generally less intense after injury. CONCLUSIONS: Increased ASIC-3 in inflamed intestine suggests a role in pain or dysmotility, for which ASICs represent new therapeutic targets.

Separation of human immunodeficiency virus type 1 replication from nef-mediated pathogenesis in the human thymus.

Human immunodeficiency virus type 1 (HIV-1) is frequently attenuated after long-term culture in vitro. The attenuation process probably involves mutations of functions required for replication and pathogenicity in vivo. Analysis of attenuated HIV-1 for replication and pathogenicity in vivo will help to define these functions. In this study, we examined the pathogenicity of an attenuated HIV-1 isolate in a laboratory worker accidentally exposed to a laboratory-adapted HIV-1 isolate. Using heterochimeric SCID-hu Thy/Liv mice as an in vivo model, we previously defined HIV-1 env determinants (HXB/LW) that reverted to replicate in vivo (L. Su, H. Kaneshima, M. L. Bonyhadi, R. Lee, J. Auten, A. Wolf, B. Du, L. Rabin, B. H. Hahn, E. Terwilliger, and J. M. McCune, Virology 227:46-52, 1997). Here we further demonstrate that HIV-1 replication in vivo can be separated from its pathogenic activity, in that the HXB/LW virus replicated to high levels in SCID-hu Thy/Liv mice, with no significant thymocyte depletion. Restoration of the nef gene in the recombinant HXB/LW genome restored its pathogenic activity, with no significant effect on HIV-1 replication in the thymus. Our results suggest that in vitro-attenuated HIV-1 lacks determinants for pathogenicity as well as for replication in vivo. Our data indicate that (i) the replication defect can be recovered in vivo by mutations in the env gene, without an associated pathogenic phenotype, and (ii) nef can function in the HXB/LW clone as a pathogenic factor that does not enhance HIV-1 replication in the thymus. Furthermore, the HXB/LW virus may be used to study mechanisms of HIV-1 nef-mediated pathogenesis in vivo.

Excision of hemivertebrae in the management of congenital scoliosis involving the thoracic and thoracolumbar spine.

We present a study of ten consecutive patients who underwent excision of thoracic or thoracolumbar hemivertebrae for either angular deformity in the coronal plane, or both coronal and sagittal deformity. Vertebral excision was carried out anteriorly alone in two patients. Seven patients had undergone previous posterior spinal fusion. Their mean age at surgery was 13.4 years (6 to 19). The mean follow-up was 78.5 months (20 to 180). The results were evaluated by radiological review of the preoperative, postoperative and most recent follow-up films. The mean preoperative coronal curve was 78.2 degrees (30 to 115) and was corrected to 33.9 degrees (7 to 58) postoperatively, a mean correction of 59%. Preoperative coronal decompensation of 35 mm was improved to 11 mm postoperatively. Seven patients had significant coronal decompensation preoperatively, which was corrected to a physiological range postoperatively. There were no major complications and no neurological damage. We have shown that resection of thoracic and thoracolumbar hemivertebrae can be performed safely, without undue risk of neurological compromise, in experienced hands.

Disinhibition and expectancy in risk for alcohol use: comparing black and white college samples.

OBJECTIVE: This study tested several predictions of the "acquired preparedness" model in both black and white samples of college students. The acquired preparedness model holds that trait disinhibition affects alcohol-related learning and, ultimately, alcohol use. This model maintains that the reward focus typical of disinhibited individuals increases the likelihood of forming overly positive expectancies about the effects of alcohol. Alcohol expectancy, then, acts as a mediator of the relationship of disinhibition and drinking behavior. METHOD: Participants (N = 479, 341 women) were 279 white and 200 black college students. Self-reported alcohol expectancy, disinhibition and drinking behavior were assessed. Covariance structure analysis was used to test hypotheses separately for each sample, controlling for socioeconomic status. RESULTS: Black participants scored significantly lower on disinhibition, expectancy and drinking. However, invariance testing indicated that the relationships between these variables were not different across groups. Results were consistent with the stated hypotheses in both samples--alcohol expectancy functioned as a mediator of the disinhibition-drinking relationship. Results did not differ across expectancy content. CONCLUSIONS: These results provide support for the validity of the acquired preparedness model. Despite mean differences in risk and drinking levels between black and white samples, psychosocial learning appears to mediate the influence of disinhibition on drinking for both groups.

The impact of skin disease on the quality of life of adolescents.

Though relatively well-investigated in adults, the impact of skin disease on the health-related quality of life (HRQL) of adolescents has only recently begun to be systematically evaluated. The primary goal of this article is to critically review previous research that has examined the relationship between HRQL and three types of skin disease commonly experienced by adolescents, namely acne vulgaris, alopecia areata, and atopic dermatitis. A secondary goal is to provide strategies to adolescent medicine physicians that will enable them to more effectively manage the psychological components of their patients dermatological conditions.

Clinical under staging of high risk nonmuscle invasive urothelial carcinoma treated with radical cystectomy.

PURPOSE: The role of radical cystectomy in patients with nonmuscle invasive urothelial carcinoma of the bladder remains controversial. The risk of overtreatment must be balanced against the potential benefit of aggressive therapy. We reviewed our results in these patients with a particular emphasis on clinical under staging. MATERIALS AND METHODS: We reviewed the records of 214 consecutive patients who underwent radical cystectomy for urothelial carcinoma between April 1995 and August 1999, focusing on those with nonmuscle invasive, stages T1 or less disease. We assessed clinical and pathological data as well as outcomes based on pathological disease extent. RESULTS: A total of 78 patients (36%) underwent radical cystectomy for clinical stages T1 or less disease. Indications included disease refractory to intravesical therapy in 29 cases (37%), pathological findings reflective of high grade stage T1 or multifocal disease in 26 (33%), radiographic suspicion of invasive disease in 15 (20%) and severe symptoms in 8 (10%). Cancer was clinically under staged with stages pT2 or greater disease in 31 patients (40%) according to final pathology results. Under staging was most pronounced in the 10 patients (67%) with suspicious radiography and in the 18 (64%) with absent muscle in the biopsy specimen. Of the 78 patients with pathological stages pT1 disease or less 98% had no evidence of disease compared to 65% with stages pT2 or greater disease (p <0.01). CONCLUSIONS: Despite the intent to perform early cystectomy a significant percent of patients harbored occult muscle invasive and/or metastatic disease. In clinical and pathological, superficial stages T1 or less cases disease-free survival was excellent. Due to these results, the selection of high risk superficial transitional cell carcinoma cases for continued bladder sparing treatment should include uninvolved muscle on biopsy and absent radiographic suspicion of invasion.

Radical cystectomy is safe in elderly patients at high risk.

PURPOSE: Radical cystectomy is standard treatment for bladder cancer in healthy individuals. We determined the safety of radical cystectomy in elderly patients at high risk. MATERIALS AND METHODS: We reviewed the records of all patients who underwent radical cystectomy at our institution between January 1994 and June 2000. Of these 382 patients we identified 44 who were elderly and at high risk, as defined by age 75 years or greater and American Society of Anesthesiologists classification 3 or greater. We examined postoperative care, perioperative minor/major complications, the mortality rate and the need for rehospitalization. RESULTS: Median age of the 44 patients was 77.5 years (range 75 to 87). American Society of Anesthesiologists class was 3 in 40 patients and 4 in 4. Median hospitalization was 7 days (range 4 to 20). Postoperatively 31 of the 44 patients (70%) were transferred directly to the general urology floor, while cardiac monitoring was required postoperatively in 30%. Nine of these patients were transferred to a step-down unit and the remaining 4 required surgical intensive care unit admission. Minor and major complications developed in 10 (22.7%) and 2 (4.5%) cases, respectively. No patients died in the perioperative period and 4 patients were hospitalized within 6 months of discharge home. CONCLUSIONS: Our results support the safety of radical cystectomy in elderly patients at high risk. Acceptable perioperative morbidity and mortality may be achieved without routine intensive monitoring postoperatively.

Nonprescription tinted eyewear optical accuracy study.

BACKGROUND: Nonprescription tinted eyewear, commonly referred to as noncorrective sunglasses or plano sun eyewear, often induce measurable amounts of prismatic deviation. With high-wrap eyewear this effect becomes more pronounced. The purpose of this project was to assess the amount of horizontal and vertical prismatic deviation induced by some popular premium plano sun eyewear intended for use by athletes. METHODS: Prismatic deviations for two identical pairs of high-wrap, steep base curve, plano sun eyewear from each of six prominent national brands were measured in both primary gaze and along a peripheral line of sight 30 degrees to the right of straight-ahead. RESULTS: Most of the eyewear induced base-out and base-down prism in each lens in primary gaze. All eyewear induced base-in prism with temporal gaze and base-out prism with nasal gaze at 30 degrees laterally. Most eyewear induced base-down prism with lateral gaze as well. CONCLUSIONS: Plano sun eyewear is often purchased for use in bright environments during visually demanding sports, such as golf, baseball, and volleyball. It is well-documented that athletes possess superior visual function as compared to nonathletes or lesser-level athletes. Further studies are indicated to determine the impact of this prism on the average wearer and the elite athlete.

Estimated blood loss and transfusion requirements of radical cystectomy.

PURPOSE: Radical cystectomy has been associated with significant blood loss and/or transfusion requirement. We defined and characterized blood loss and transfusion parameters in this population. MATERIALS AND METHODS: We reviewed the records of 304 consecutive patients who underwent radical cystectomy and urinary diversion between October 1995 and July 2000. Charts were examined, and univariate and multivariate logistic regression analysis was performed to evaluate estimated blood loss and the transfusion requirement. RESULTS: Complete blood loss data were available in 297 cases. Overall 45% of patients had anemia preoperatively. Median estimated blood loss was 600 ml. (range 100 to 3,000). On univariate analysis increased estimated blood loss was related to patient age, American Society of Anesthesiologists score, longer operative time and paralytic ileus. Overall transfusion was done in 88 of 297 cases (30%) with a median requirement of 2 units (range 1 to 10). The transfusion rate in male and female patients was 26% and 40%, respectively (p <0.05). On univariate analysis female gender, ileal conduit diversion and lower preoperative hematocrit correlated with transfusion need (p = 0.04, <0.001 and <0.001, respectively). On multivariate logistic regression analysis lower preoperative hematocrit, increased estimated blood loss, major complications and ileal conduit diversion type correlated with a higher transfusion rate (odds ratio 8.34, 5.88 and 4.60, respectively). CONCLUSIONS: Acute blood loss anemia is common in patients undergoing radical cystectomy, and predicting blood loss and transfusion requirements remains difficult. These data indicate the need for continued refinement in surgical techniques to decrease blood loss as well as for strategies designed to decrease the need for blood transfusion.

Health related quality of life assessment after radical prostatectomy in men with prostate specific antigen only recurrence.

PURPOSE: The health related quality of life assessment is becoming increasingly important among patients with prostate cancer. Meanwhile, treatment of patients with increasing prostate specific antigen (PSA) after radical retropubic prostatectomy remains controversial. We attempt to define the impact of PSA recurrence on the health related quality of life of patients after radical retropubic prostatectomy. MATERIALS AND METHODS: Of 604 consecutive patients who underwent radical retropubic prostatectomy between March 1991 and September 1998, 510 (84%) were available for followup. Each patient was mailed the RAND 36-Item Health Survey and University of California, Los Angeles, Prostate Cancer Index questionnaire. A total of 348 (70%) questionnaires were returned. Health related quality of life scores were then compared between patients with and without PSA recurrence. A multivariate analysis was also performed to elucidate further the cause of differences between the groups. RESULTS: Overall, 88 (25%) patients had PSA recurrence. In regard to health related quality of life there were small (less than 10%) but statistically significant differences in 2 of 4 physical health domains (RAND 36-Item Health Survey). There was a significant decrease in only 1 category of the mental health domain for patients with PSA recurrence. Only sexual function was statistically lower on the University of California, Los Angeles, Prostate Cancer Index. This result reflects the lower incidence of nerve sparing in these patients, as confirmed by the multivariate analysis. Overall patient satisfaction was similar between those with and without PSA recurrence (76% and 79%, respectively). CONCLUSIONS: Our study demonstrates small health related quality of life differences in patients with biochemical PSA recurrence versus those without. These findings provide a baseline assessment of general and disease specific health related quality of life domains among these patients. Future studies should focus on differences in the measure of cancer anxiety before and after administration of adjuvant therapy in these asymptomatic patients.
