RESUMEN

BACKGROUND: Hidradenitis suppurativa (HS), a chronic inflammatory disease that affects apocrine gland-bearing skin, has a significant impact on patients' quality of life. Estimates of the epidemiologic prevalence of HS are highly variable, and clinical data on disease characteristics and patient burden of disease remain limited. OBJECTIVE: The primary objective of this study was to determine the number of patients with HS attending dermatology clinics in a hospital setting in Ireland (within a 6-month time period). Secondary objectives included the assessment of disease characteristics and the collection of patient responses on disease burden and work productivity. METHODS: This was an epidemiologic, non-interventional, cross-sectional study across four dermatology clinics in Ireland over a 6-month time period. The disease prevalence was estimated by calculating the percentage of total patients with a diagnosis of HS (the primary population) across the selected sites. Secondary analyses were performed using the full analysis set, which consisted of eligible adults (≥18 years of age) from the primary population who provided informed consent. Data from these analyses are presented as descriptive summary statistics, with the use of an analysis of covariance for continuous endpoints. RESULTS: The prevalence of HS across the four selected sites was estimated at 1.4% (95% CI, 1.24-1.62). One hundred and fifty eligible patients comprised the full analysis set. The majority of participants were white (95.3%), female (70.0%), cigarette smokers (56.0%) and overweight or obese (body mass index ≥25 kg/m2 , 81.8%). Most patients for whom data were available presented with Hurley stage II (50.4%), and more than a third of the full analysis set had a relative with HS (34.7%). Questionnaire responses revealed a profound impact on quality of life, including diminished work productivity and various psychological comorbidities. CONCLUSION: This study offers insight into the clinical features and disease burden of hidradenitis suppurativa in an Irish population.

RESUMEN

BACKGROUND: Despite the rising incidence of melanoma, medical students have progressively fewer opportunities to encounter patients with this important condition. Curricula tend to attach the greatest value to intellectual forms of learning. However, compared with intellectual learning, experiential learning affords students deep insights about a condition. Doctors who experience ill health are more empathic towards patients. However, opportunities to learn about cancer experientially are limited. Temporary transfer tattoos can simulate the ill health associated with melanoma. We reasoned that if doctors who have been sick are more empathic temporarily 'having' melanoma might have a similar effect. OBJECTIVES: To explore the impact of wearing a melanoma tattoo on medical students' understanding of patienthood and attitudes towards patients with melanoma. METHODS: Ten fourth-year medical students were recruited to a simulation. They wore a melanoma tattoo for 24 h and listened to a patient's account of receiving their diagnosis. Data were captured using audio diaries and face-to-face interviews, transcribed and analysed phenomenologically using the template analysis method. RESULTS: There were four themes: (i) melanoma simulation: opening up new experiences; (ii) drawing upon past experiences; (iii) a transformative introduction to patienthood; (iv) doctors in the making: seeing cancer patients in a new light. CONCLUSIONS: By means of a novel simulation, medical students were introduced to lived experiences of having a melanoma. Such an inexpensive simulation can prompt students to reflect critically on the empathetic care of such patients in the future.

RESUMEN

OBJECTIVES: The Shape of Training report recommended that full registration is aligned with medical school graduation. As part of a General Medical Council-funded study about the preparedness for practice of UK medical graduates, we explored UK stakeholders' views about this proposal using qualitative interviews (30 group and 87 individual interviews) and Framework Analysis. SETTING: Four UK study sites, one in each country. PARTICIPANTS: 185 individuals from eight stakeholder groups: (1) foundation year 1 (F1) doctors (n=34); (2) fully registered trainee doctors (n=33); (3) clinical educators (n=32); (4) undergraduate/postgraduate Deans, and Foundation Programme Directors (n=30); (5) other healthcare professionals (n=13); (6) employers (n=7); (7) policy and government (n=11); (8) patient and public representatives (n=25). RESULTS: We identified four main themes: (1) The F1 year as a safety net: patients were protected by close trainee supervision and 'sign off' to prevent errors; trainees were provided with a safe environment for learning on the job; (2) Implications for undergraduate medical education: if the proposal was accepted, a 'radical review' of undergraduate curricula would be needed; undergraduate education might need to be longer; (3) Implications for F1 work practice: steps to protect healthcare team integration and ensure that F1 doctors stay within competency limits would be required; (4) Financial, structural and political implications: there would be cost implications for trainees; clarification of responsibilities between undergraduate and postgraduate medical education would be needed. Typically, each theme comprised arguments for and against the proposal. CONCLUSIONS: A policy change to align the timing of full registration with graduation would require considerable planning and preliminary work. These findings will inform policymakers' decision-making. Regardless of the decision, medical students should take on greater responsibility for patient care as undergraduates, assessment methods in clinical practice and professionalism domains need development, and good practice in postgraduate supervision and support must be shared.

RESUMEN

BACKGROUND: There is accumulating evidence that long-term disability and disease progression in multiple sclerosis (MS) are due to prolonged sodium channel opening along demyelinated axons. Despite good evidence in animal models of MS that partial voltage-gated sodium channel (VGSC) blockade reduces disease progression, little is known about its effects in patients, despite widespread use of such agents in the symptomatic management of MS. OBJECTIVE: To determine if long-term exposure to the VGSC-blocking drug carbamazepine (CBZ) alters disease progression in MS. METHODS: Using a retrospective chart review of patients diagnosed with MS, we compared progression of disability between patients exposed the VGSC blocker CBZ with those who were not exposed to the drug. Both whole-group and matched case-control analyses were performed after correcting for the influence of age, gender, MS subtype, expanded disability status score at diagnosis, use of disease-modifying therapy, and year of initial therapy. The multiple sclerosis severity scale (MSSS) was used as a measure of disease severity. The primary outcome measure was MSSS score difference between groups. RESULTS: Four hundred patients were included; 51 received CBZ symptomatic therapy (average duration of therapy 27 months). There was no significant difference in mean MSSS between the two groups in either the whole group comparison (p = 0.63) or the matched analysis (p = 0.12). CONCLUSION: Despite preclinical evidence suggesting a neuroprotective role of VGSC blockers in animal models of MS, this retrospective study suggests that long-term exposure to the VGSC-blocking drug CBZ fails to alter long-term disability and disease progression in MS patients.

RESUMEN

PURPOSE: Non-steroidal anti-inflammatory drugs (NSAIDs) have many anticarcinogenic properties via the inhibition of cyclooxygenase 2 (COX-2). Only one study, a cohort study examining risk of all cancers, investigated their role in cervical cancer with inconsistent findings between non-aspirin NSAIDs and aspirin. The aim of this study was to further investigate NSAID/aspirin use and cervical cancer risk. METHODS: Using the United Kingdom Clinical Practice Research Datalink, 724 women diagnosed with cervical cancer between 1 January, 1995 and December 2010 were compared to 3479 women (without cervical cancer) matched on year of birth and general practice. Conditional logistic regression analysis adjusted for smoking, sexually transmitted infections, HRT and contraceptive use, was used to calculate odds ratios (OR) and 95% confidence intervals (CI) for cervical cancer risk among users of any oral NSAIDs, non-aspirin NSAIDs and aspirin, as assessed from primary care prescribing data. RESULTS: Excluding the year prior to diagnosis, there was no association in adjusted analyses between ever vs. never use of an NSAID (OR 0.92, 95% CI 0.77-1.09), non-aspirin NSAID (OR 0.95, 95% CI 0.80-1.13) or low-dose aspirin (OR 1.07, 0.80-1.44) and cervical cancer risk. In analysis of daily defined doses, there was no association with cervical cancer risk comparing the highest users to non-users of NSAIDs (OR 0.98, 95% CI 0.69-1.39) or non-aspirin NSAIDs (OR 1.00, 95% CI 0.70-1.43) or low-dose aspirin (OR 1.04, 95% CI 0.59-1.81). CONCLUSION: This large historical cohort study found no evidence of an association between non-aspirin NSAID or aspirin use and cervical cancer risk.

RESUMEN

BACKGROUND: Evidence supports the use of exercise for chronic low back pain (CLBP); however, adherence is often poor due to ongoing pain. Auricular acupuncture is a form of pain relief involving the stimulation of points on the outer ear corresponding with specific body parts. It may be a useful adjunct to exercise in managing CLBP; however, there is only limited evidence to support its use with this patient group. METHODS/DESIGN: This study was designed to test the feasibility of an assessor-blind randomised controlled trial which assess the effects on clinical outcomes and exercise adherence of adding manual auricular acupuncture to a personalised and supervised exercise programme (PEP) for CLBP. No sample size calculation has been carried out as this study aims to identify CLBP referral rates within the catchment area of the study site. The researchers aim to recruit four cohorts of n = 20 participants to facilitate a power analysis for a future randomised controlled trial. A computer generated random allocation sequence will be prepared centrally and used to allocate participants by cohort to one of the following interventions: 1) six weeks of PEP plus manual auricular acupuncture; 2) six weeks of PEP alone. Both groups will also complete a further six weeks of self-paced exercise with telephone follow-up support. In addition to a baseline and exit questionnaire at the beginning and end of the study, the following outcomes will be collected at baseline, and after 7, 13 and 25 weeks: pain frequency and bothersomeness, back-specific function, objective assessment and recall of physical activity, use of analgesia, perceived self-efficacy, fear avoidance beliefs, and beliefs about the consequences of back pain. Since this is a feasibility study, significance tests will not be presented, and treatment effects will be represented by point estimates and confidence intervals. For each outcome variable, analysis of covariance will be performed on the data, conditioning on the baseline value. DISCUSSION: The results of this study investigating the adjuvant effects of auricular acupuncture to exercise in managing CLBP will be used to inform the design of a future multi-centre randomised controlled trial. TRIAL REGISTRATION: Current Controlled Trials ISRCTN94142364.

RESUMEN

OBJECTIVES: To evaluate the impact of two different modes of shoulder injection training on the level of confidence and number of injections performed by general practitioners (GPs) METHODS: Demographic details, and information on referrals for shoulder problems, shoulder joint injection activity, and confidence in the six months before training were obtained for 40 GP principals at baseline. Standardised training in the techniques of shoulder joint injection using rubber mannequins was given to all GPs. Twenty of these GPs were randomly allocated to receive additional training on patients in hospital joint injection clinics. Six months after both forms of training the shoulder injection and referral activities of all GPs were reassessed. RESULTS: Both training groups had comparable demographic characteristics and baseline clinical activity. GPs who had additional training with patients reported a marked increase in their level of confidence in performing shoulder injections and the number performed. The number of shoulder referrals did not differ between the groups CONCLUSION: Training on patients in addition to conventional training on mannequins increased GPs' shoulder injection activity and their level of confidence. Hospital injection clinics may provide a suitable setting in which to train GPs interested in developing their shoulder joint injection skills.

RESUMEN

A questionnaire was sent to 400 general practitioners (GPs), concerning prostate-specific antigen (PSA) screening. Regarding the indications for PSA testing, 80% of GPs test men with urinary tract symptoms, 65% test men with a positive family history, 62% test on patient request, and 21% test men with unrelated symptoms. When PSA is measured, 91% of GPs inform their patient, and 71% discuss the significance of an abnormal result. The mean age range for PSA testing was from 50 years, without an upper age limit. The mode PSA threshold for referral was 6.6 ng/ml. De facto PSA screening appears to be widely practised.

RESUMEN

OBJECTIVES: To determine whether diagnostic triage by general practitioners (GPs) or rheumatology nurses (RNs) can improve the positive predictive value of referrals to early arthritis clinics (EACs). METHODS: Four GPs and two RNs were trained in the assessment of early inflammatory arthritis (IA) by four visits to an EAC supervised by hospital rheumatologists. Patients referred to one of three EACs were recruited for study and assessed independently by a GP, an RN and one of six rheumatologists. Each assessor was asked to record their clinical findings and whether they considered the patient to have IA. Each was then asked to judge the appropriateness of the referral according to predetermined guidelines. The rheumatologists had been shown previously to have a satisfactory level of agreement in the assessment of IA. RESULTS: Ninety-six patients were approached and all consented to take part in the study. In 49 cases (51%), the rheumatologist judged that the patient had IA and that the referral was appropriate. The assessments of GPs and RNs were compared with those of the rheumatologists. Levels of agreement were measured using the kappa value, where 1.0 represents total unanimity. The kappa value was 0.77 for the GPs when compared with the rheumatologists and 0.79 for the RNs. Significant stiffness in the morning or after rest and objective joint swelling were the most important clinical features enabling the GPs and RNs to discriminate between IA and non-IA conditions. CONCLUSION: Diagnostic triage by GPs or RNs improved the positive predictive value of referrals to an EAC with a degree of accuracy approaching that of a group of experienced rheumatologists.

RESUMEN

OBJECTIVES: To investigate the numbers and types of joint and soft tissue injections performed by general practitioners (GPs) and to explore attitudes to training in joint and soft tissue injection and perceived barriers to performing injections. METHODS: A self administered questionnaire was mailed to a random sample of 410 (30%) of 1367 GPs in Northern Ireland. Two mailings were used to increase the response rate. Questions explored the GPs' demographic characteristics, types and numbers of injections performed, previous training experience, attitudes towards training, and perceived barriers. RESULTS: The overall response rate was 75%. Practitioners who were men, worked in a "rural" or "mixed" locality, and had had a previous post in rheumatology, orthopaedics, or sports medicine were more likely to perform joint and soft tissue injections. Forty six per cent of GPs did not currently perform any injections; 5% of GPs performed most of the injections in the community. Injections into the shoulder, knee, and lateral epicondylitis were found to be the most commonly performed injections. The GPs preferred to train on "real patients" rather than "mannequin models". Those GPs who had trained on "real patients" were more likely to perform injections. The main perceived barrier to performing joint and soft tissue injections in the community was the "inability to maintain injection skills". CONCLUSION: Postgraduate training, methods of training, and the ability to maintain injection skills seemed to be determinants affecting GP confidence and the amount of joint and soft tissue injections that they performed. Most injections were performed by a few GPs in the community. These findings may have implications for the developing role of GP specialists in primary care trusts.

RESUMEN

This study compared the effects of oral alendronate and intranasal calcitonin for treatment of osteoporosis in postmenopausal women. Women at least 5 yr postmenopause (n = 299) were randomized to either 10 mg alendronate, matching alendronate placebo, or open-label intranasal calcitonin 200 IU daily for 12 months. Hip and spine bone mineral density (BMD) and markers of bone turnover were measured, and safety and tolerability were assessed. Alendronate produced greater increases in BMD than calcitonin at 12 months at the lumbar spine (5.16% vs. 1.18%; P < 0.001), trochanter (4.73% vs. 0.47%; P < 0.001), and femoral neck (2.78% vs. 0.58%; P < 0.001). Changes in BMD with calcitonin were greater than with placebo at the femoral neck, but were not different from placebo at either the trochanter or lumbar spine. Greater decreases in bone turnover were seen with alendronate than with calcitonin (serum bone-specific alkaline phosphatase, 43% vs. 9%, P < 0.001; urinary N-telopeptide, 62% vs. 11%, P < 0.001). Similar percentages of patients in each group reported an adverse experience during the study. We conclude that, in postmenopausal women with osteoporosis, 12 months of therapy with alendronate produced significantly greater increases in BMD of the hip and spine and greater decreases in bone turnover than intranasal calcitonin.

RESUMEN

BACKGROUND: Montelukast, an oral, once-daily leukotriene receptor antagonist, provides protection against exercise-induced bronchoconstriction. OBJECTIVE: To evaluate the effect of 8 weeks of therapy with salmeterol aerosol or montelukast on exercise-induced bronchoconstriction in adults with asthma. DESIGN: 8-week multicenter, randomized, double-blind study. SETTING: 17 asthma treatment centers in the United States. PATIENTS: 191 adults with asthma who had documented exercise-induced bronchoconstriction. INTERVENTION: Qualified patients were randomly assigned to double-blind treatment with montelukast (10 mg once in the evening) or salmeterol (50 microg [2 puffs] twice daily). MEASUREMENTS: Changes in pre-exercise and postexercise challenge values; percentage inhibition in the maximal percentage decrease in FEV1; the area above the FEV1-time curve; and time to recovery of FEV1 at days 1 to 3, week 4, and week 8 of treatment. RESULTS: By day 3, similar and statistically significant reductions in maximal percentage decrease in FEV1 were seen with both therapies. Sustained improvement occurred in the montelukast group at weeks 4 and 8; at these time points, the bronchoprotective effect of salmeterol decreased significantly. At week 8, the percentage inhibition in the maximal percentage decrease in FEV1 was 57.2% in the montelukast group and 33.0% in the salmeterol group (P = 0.002). By week 8, 67% of patients receiving montelukast and 46% of patients receiving salmeterol had a maximal percentage decrease in FEV1 of less than 20%. CONCLUSIONS: The bronchoprotective effect of montelukast was maintained throughout 8 weeks of study. In contrast, significant loss of bronchoprotection at weeks 4 and 8 was seen with salmeterol. Long-term administration of montelukast provided consistent inhibition of exercise-induced bronchoconstriction at the end of the 8-week dosing interval without tolerance.

RESUMEN

Many patients with glaucoma or ocular hypertension initially receive beta-blocker monotherapy to control intraocular pressure (IOP), but some of these patients will require an additional IOP-lowering agent within 1 year. This active-controlled, double-masked, randomized, multicenter, 12-week study compared the effectiveness and tolerability of dorzolamide hydrochloride ophthalmic solution 2% TID with those of pilocarpine hydrochloride 2% QID as adjunctive therapy to timolol maleate ophthalmic gel-forming solution (TG) 0.5% QD as measured by changes in IOP and occurrence of adverse events. One hundred ninety-four patients with open-angle glaucoma or ocular hypertension participated in this study. Their mean age was approximately 63 years. Slightly more than one half were white, and approximately one third were black. After a 3-week run-in period during which all patients received TG 0.5% QD, patients with an IOP of > or = 22 mm Hg at the morning trough measurement were randomly assigned to receive additional double-masked therapy with either dorzolamide or pilocarpine. The primary outcome measure was the mean change in IOP at the morning trough measurement from baseline to week 12. The secondary outcome measure was the mean change in IOP at the morning peak measurement from baseline to week 12. There was no significant difference in IOP-lowering effect between the 2 drugs at either morning trough or morning peak. The mean change in IOP at morning trough was -3.17 mm Hg (-12%) in patients receiving dorzolamide; it was -3.45 mm Hg (-13%) in patients receiving pilocarpine. The mean change in IOP at morning peak was -2.25 mm Hg (-10%) for patients who received dorzolamide and -2.51 mm Hg (-11%) for those who received pilocarpine. In the pilocarpine group, 62 (63%) patients experienced > or =1 adverse event compared with 35 (36%) patients in the dorzolamide group (P < 0.001). Twenty-one (21%) patients in the pilocarpine group discontinued treatment because of an adverse event compared with 2 (2%) patients in the dorzolamide group (P < 0.001). These results demonstrate that dorzolamide and pilocarpine were equally effective as adjunctive therapy in lowering IOP but that dorzolamide was better tolerated.

RESUMEN

PURPOSE: We assess the effect of finasteride, a 5alpha-reductase inhibitor, on objective voiding parameters in men with lower urinary tract symptoms and benign prostatic enlargement on digital rectal examination (known as clinical benign prostatic enlargement) in a double-blind placebo controlled multicenter study using strict standard pressure flow study techniques. MATERIALS AND METHODS: A modification of the Abrams-Griffiths nomogram was used by 1 reader to ensure that all patients met objective criteria for bladder outlet obstruction at baseline. After performing a pressure flow study patients with obstruction were randomized 2:1 to receive 5 mg. finasteride (81) or placebo (40) daily. A second pressure flow study was performed at month 12. At baseline and month 12 free urinary flow studies and transrectal ultrasound were performed, and International Prostate Symptom Score questionnaires were completed. Patients were treated between May 1994 and July 1996. RESULTS: Finasteride caused a significant decrease (-8.1 cm. water) in detrusor pressure at maximum flow (p <0.05 versus placebo p = 0.02), increase (+1.1 ml. per second) in maximum flow rate (p <0.05 versus placebo p = 0.02) and decrease (-22.8%) in prostate volume (p <0.05 versus placebo p <0.001). Men with prostates larger than 40 cc had greater improvement in detrusor pressure at maximum flow (between group difference -14.5 cm. water, 95% confidence interval -26.2 to -2.6, p = 0.02) and maximum flow rate (mean treatment effect +1.6 ml. per second, 95% confidence interval -0.2 to 3.0, p = 0.02) compared to those with prostates 40 cc or less (between group differences not significant).
