Abstract
Camurati-Engelmann disease (CED) is a rare autosomal dominant type of bone dysplasia. This review is based on the unpublished and detailed clinical, radiological, and molecular findings in 14 CED families, comprising 41 patients, combined with data from 10 other previously reported CED families. For all 100 cases, molecular evidence for CED was available, as a mutation was detected in TGFB1, the gene encoding transforming growth factor (TGF) beta1. Pain in the extremities was the most common clinical symptom, present in 68% of the patients. A waddling gait (48%), easy fatigability (44%), and muscle weakness (39%) were other important features. Radiological symptoms were not fully penetrant, with 94% of the patients showing the typical long bone involvement. A large percentage of the patients also showed involvement of the skull (54%) and pelvis (63%). The review provides an overview of possible treatments, diagnostic guidelines, and considerations for prenatal testing. The detailed description of such a large set of CED patients will be of value in establishing the correct diagnosis, genetic counselling, and treatment.

Abstract
Culture for Bordetella pertussis (B. pertussis) is the traditional gold standard for laboratory diagnosis of pertussis but is insensitive, especially later in the course of illness and in vaccinated persons. Interpretation of serology is limited by the lack of an appropriate reference standard. An outbreak of pertussis in a crowded boarding-school dormitory allowed evaluation of laboratory correlates of infection. Questionnaires, serum samples and throat swabs were collected from members of the exposed group. Serum samples from unexposed controls of a similar age group were used for comparison. B. pertussis PCR was performed on throat swabs, and sera were tested for IgA antibodies against whole-cell (WC) B. pertussis antigen and IgG antibodies to pertussis toxin (PT). The Centers for Disease Control and Prevention definition for pertussis was used to define clinical cases. We evaluated the use of a previously published cut-off for PT IgG of 125 EIA units (EU)/ml. Completed questionnaires were obtained from 115 students, of whom 85 (74%) reported coughing symptoms, including 32 (28%) who met the clinical case definition for pertussis. B. pertussis was detected by PCR in 17 (15%) and WC IgA in 22 (19%) students; neither correlated with symptoms, but dormitory of residence strongly predicted PCR status. The mean PT IgG geometric mean concentration, in this situation of high pertussis exposure, correlated with severity of symptoms and was significantly higher in both symptomatic and asymptomatic children exposed during the outbreak (P < 0.001) than in control children. A cut-off for PT IgG of 125 EU/ml was too high in an outbreak situation to be sensitive enough to identify pertussis cases. A case of pertussis in a crowded boarding-school dormitory resulted rapidly in an outbreak. Serology and PCR were useful in identifying the outbreak and commencing disease control measures. The use of serology has mostly been evaluated in community serosurveys, where it is not possible to determine if immunity reflects vaccination, asymptomatic disease or symptomatic disease. This outbreak gave us the opportunity to evaluate the value of serology and PCR in the presence of confirmed exposure to pertussis.

Abstract
Lafora disease (LD) is the most common teenage-onset progressive myoclonus epilepsy. It is caused by recessive mutations in the EPM2A or EPM2B genes. The authors describe a family with three affected members with no mutations in either gene. Linkage and haplotype analyses exclude both loci from causative involvement in this family. Therefore, a third LD locus is predicted. Its identification will be a crucial element in the understanding of the biochemical pathway underlying the generation of Lafora bodies and LD.

Abstract
BACKGROUND Helicobacter pylori (H pylori) is the main cause of peptic ulcer disease. The role of H pylori in non-ulcer dyspepsia is less clear. OBJECTIVES To determine the effect of H pylori eradication on dyspepsia symptoms in patients with non-ulcer dyspepsia. SEARCH STRATEGY Trials were identified through electronic searches of the Cochrane Controlled Trials Register (CCTR), MEDLINE, EMBASE, CINAHL and SIGLE, using appropriate subject headings and keywords, searching bibliographies of retrieved articles, and through contacts with experts in the fields of dyspepsia and with pharmaceutical companies. These searches were updated in October 2004. SELECTION CRITERIA All parallel group randomised controlled trials (RCTs) comparing drugs to eradicate H pylori with placebo or other drugs known not to eradicate H pylori for patients with non-ulcer dyspepsia. DATA COLLECTION AND ANALYSIS Data were collected on individual and global dyspeptic symptom scores, quality of life measures and adverse effects. Dyspepsia outcomes were dichotomised into minimal/resolved versus same/worse symptoms. MAIN RESULTS Seventeen randomised controlled trials were included in the systematic review. Fourteen trials compared antisecretory dual or triple therapy with placebo antibiotics +/- antisecretory therapy, and evaluated dyspepsia at 3-12 months. Thirteen of these trials gave results as dichotomous outcomes evaluating 3186 patients and there was no significant heterogeneity between the studies. There was a 8% relative risk reduction in the H pylori eradication group (95% CI = 3% to 12%) compared to placebo. The number needed to treat to cure one case of dyspepsia = 18 (95% CI = 12 to 48). A further three trials compared Bismuth based H pylori eradication with an alternative pharmacological agent. These trials were smaller and had a shorter follow-up but suggested H pylori eradication was more effective than either H2 receptor antagonists or sucralfate in treating non-ulcer dyspepsia. AUTHORS' CONCLUSIONS H pylori eradication therapy has a small but statistically significant effect in H pylori positive non-ulcer dyspepsia. An economic model suggests this modest benefit may still be cost-effective but more research is needed.

Abstract
Kidney cancer remains relatively rare, but incidence and mortality rates are reported to be rising steadily across the world. To determine if such increases were occurring in the UK, we examined the rates of incidence and mortality in different histological subtypes of kidney cancer in the Northern and Yorkshire region of England. Details of all 8741 cases diagnosed between 1978 and 1997 were extracted from the population-based Northern and Yorkshire Cancer Registry. For all types of tumour, both incidence and mortality rates increased over the study period. Overall age-standardised incidence rates increased by 86% for renal parenchymal carcinoma (RPC) (80% for males, 90% for females) from 2.8 to 5.2 cases per 100000 (3.8-6.8 male, 2.0-3.8 female). There were incidence increases in all age groups, all Carstairs index groups and in both urban and rural populations. Although increased incidental detection of kidney tumours by improved investigational techniques may account for some of this rise, we believe it unlikely that it accounts for all of the increase observed. Potential aetiological causes for the increased rates include hypertension, smoking, a diet lacking fruit and vegetables, analgesic use and, particularly, obesity.

Abstract
Our goal was to compare direct and indirect medical costs and quality of life associated with inpatient vs outpatient autologous hematopoietic stem cell transplantation (AuHSCT). Twenty-one sequential outpatients and 26 inpatients were enrolled on this prospective trial. All candidates for AuHSCT were screened for eligibility for outpatient transplantation. Patients with either breast cancer or hematologic malignancy, insurance coverage for the outpatient procedure, one to three caregivers available to provide 24 h coverage, and no significant comorbidities were eligible to participate. Patients without caregivers or insurance coverage for outpatient transplant were accrued to the study in a consecutive manner as inpatient controls, based on willingness to participate in the quality of life portion of the study and to permit review of their hospital and billing records. Approximately half of all 139 prospective outpatient candidates were ineligible because they lacked a caregiver. Most commonly, the patient without a caregiver was single or widowed or their family and friends were needed to provide childcare. Most caregivers were college educated from families with incomes greater than US dollars 80000. Indirect costs to the caregivers totaled a median of US dollars 2520 (range US dollars 684-US dollars 4508), with the majority attributed to lost 'opportunity costs'. Overall, there were significant differences in the total costs of treatment for inpatient vs outpatient AuHSCT (US dollars 40985 vs US dollars 29210, P < 0.01)). In general, no significant differences were detected between inpatient and outpatient scores on quality of life measures. Although significant cost savings were associated with outpatient transplantation, this approach was applicable to only half of our otherwise eligible candidates because of a lack of caregivers. The financial burden associated with the caretaking role may underlie this finding.

Abstract
The University of the West Indies (UWI) comprises three campuses located on three different islands. Two of the Campuses, Mona in Jamaica and St Augustine in Trinidad & Tobago offer full medical programmes, i.e. both basic sciences and clinical training. At Cave Hill, where basic sciences courses are not offered, students are drawn from the traditional school at Mona or the Problem Based Learning (PBL) school at St Augustine to follow a common clinical programme. After 24 months of clinical training consisting of a minimum of 12 clerkships these students take identical examinations in Medicine & Therapeutics, Surgery and Obstetrics & Gynaecology. In this paper the results of the final clinical examinations at Cave Hill for the five-year period 1995-99 have been analysed, comparing the performances of students drawn from Mona with those from St Augustine. We found that, except for a few isolated cases, there were no significant differences in the performance of the two groups of students. These results suggest that the delivery of a significant component of a basic sciences programme by a well-planned PBL system is unlikely to produce substandard students at the end of their clinical training.

Abstract
BACKGROUND While being cured of cancer generally leads to a life expectancy similar to that of the general population, the extent to which other aspects of life are affected is unknown. To address these concerns, patients with hairy cell leukemia, a cancer with a very high cure rate, were queried about employment, insurance, finances, and lifestyle during and following their treatment. METHODS Study participants (n = 31) ranging in age from 24 to 73 years at the time of diagnosis (median, 49 years) were surveyed regarding changes in health and life insurance, employment, out-of-pocket medical costs, exercise, diet, and use of mental and alternative health services that occurred during or following hairy cell leukemia treatment. RESULTS Following a diagnosis of hairy cell leukemia, 61.3% of the respondents paid for some aspect of medical care in spite of having health insurance coverage at the time of diagnosis. Four respondents (12.9%) could not obtain health insurance following treatment, and the occupational choices of several individuals or their spouses were based in large part on a desire to obtain or maintain comprehensive health insurance. Of the 13 individuals who attempted to purchase life insurance, 10 had difficulty obtaining a policy or were denied coverage. Lifestyle changes were noted by 40% to 60% of respondents, and included reports of more frequent exercise, adoption of a healthier diet, and having a greater appreciation for life, loved ones, and physical health. CONCLUSIONS While hairy cell leukemia is a highly curable malignancy, cancer survivors' lives and lifestyles are altered substantially after receiving treatment for the illness.

Abstract
The purpose of this article is to describe the nursing research priorities of the National Black Nurses Association (NBNA). The NBNA is a professional nursing association representing more than 150,000 black nurses throughout the United States and the Eastern Caribbean. This article describes knowledge gaps in nursing research and presents various findings from research studies aimed at defining research priorities in nursing. Recommended research priorities are discussed that are directed toward improving the health of African Americans and other vulnerable populations. The NBNA urges the National Institutes of Health to increase funding to support research initiatives with an emphasis on women's health, particularly the health of women from diverse cultures. Nursing research programs are steadily yielding results, which enable the nursing profession to meet the goal of using the programs include identification of research priorities, acknowledging the vast disparity in nursing research today.

Abstract
OBJECTIVE To determine whether stereotactic core biopsy (SCNB) is the diagnostic method of choice for all mammographic abnormalities requiring tissue sampling. SUMMARY BACKGROUND DATA Stereotactic core needle biopsy decreases the cost of diagnosis, but its impact on the number of surgical procedures needed to complete local therapy has not been studied in a large, unselected patient population. METHODS A total of 1,852 mammographic abnormalities in 1,550 consecutive patients were prospectively categorized for level of cancer risk and underwent SCNB or diagnostic needle localization and surgical excision. Diagnosis, type of cancer surgery, and number of surgical procedures to complete local therapy were obtained from surgical and pathology databases. RESULTS The malignancy rate was 24%. Surgical biopsy patients were older, more likely to have cancer, and more likely to be treated with breast-conserving therapy than those in the SCNB group. For all types of lesions, regardless of degree of suspicion, patients diagnosed by SCNB were almost three times more likely to have one surgical procedure. However, for patients treated with lumpectomy alone, the number of surgical procedures and the rate of negative margins did not differ between groups. CONCLUSIONS Stereotactic core needle biopsy is the diagnostic procedure of choice for most mammographic abnormalities. However, for patients undergoing lumpectomy without axillary surgery, it is an extra invasive procedure that does not facilitate obtaining negative margins.

Abstract
PURPOSE We performed a randomized trial to compare the efficacy and toxicity of a new dose of flutamide (500 mg QD) with the currently recommended dose (250 mg q8h) in the treatment of advanced prostate cancer. The primary endpoints were percent of patients having normalization of prostate specific antigen (PSA), time to normalization, and percent change from baseline. Secondary endpoints were quality of life and toxicity. PATIENTS Altogether, 440 men aged 46 to 94 years (mean 71 years) with confirmed stage M(1) disease, documented PSA rise >0.2 ng/mL, ECOG status 0 to 2, no second neoplasm, no liver function tests > or = 1.5-fold normal values, and no previous treatment for metastatic disease were entered in the trial. RESULTS The PSA normalized by week 12 in 71% of the patients receiving 500-mg dose and 75% of those receiving the standard dose. The percent change in PSA was 89% and 96%, respectively. The treatment groups were not significantly different with respect to the incidence of adverse events: 71% v 68% in the 500-mg and 250-mg arms, respectively (P = 0.337). CONCLUSIONS When combined with castration, 500 mg of flutamide appears to be equally effective in lowering serum PSA and is not significantly more toxic than conventional dosing. The use of 500 mg QD instead of the standard 250 mg q8h would result in a cost savings of 30%.

Abstract
Published estimates of the volume of the sexually-dimorphic central nucleus of the medial preoptic area (MPOC) have been quite variable both within and between laboratories. To obtain MPOC volume, most experimenters began with a two-dimensional (2-D) approach. They outlined the MPOC on each of several individual sections; then they added up the area contained on each section and multiplied the total by the section thickness. A 3-D reconstruction approach, although promising, has been somewhat impractical until recently due to the requirements for highly specialized software and massive computing support. Here, we describe the application of commercially-available PC-based software to measure MPOC volume by 3-D reconstruction. Male and female Sprague-Dawley rats, 24 or 50 days of age, were perfusion-fixed with 10% neutral phosphate-buffered formaldehyde. Following processing and embedding, a series of 20-microm sagittal paraffin sections were cut and mounted onto slides. After staining with cresyl violet, they were digitized using a microscope-mounted video camera connected to a frame-grabber in a Pentium-class computer (MCID-M5+). In addition to the MPOC, the anterior commissure, fornix, paraventricular nucleus, medial division of the bed nucleus of the stria terminalis, third ventricle and the bed nucleus of the anterior commissure were identified on the screen image and outlined using a computer mouse. These outlines were then aligned and rendered in 3-D with a solid overlay. The additional areas, such as anterior commissure, form landmarks within 3-D space to improve the accuracy with which the MPOC may be located and outlined. The reconstruction provides a striking illustration of the geometric relations between the structures of the anterior hypothalamus in the male and female rat. Moreover, the volumes determined from the overlays were reproducible between repeated studies in our laboratory. Our volume measurements confirm the sexual dimorphism previously reported for MPOC volumes, and provide a relatively quick, accurate and reliable protocol that should be useful in future experimental studies of environmental estrogenic compounds.
