RESUMO

Trace minerals, have a role in immune function and a trace mineral supplement (TMS) can improve animal health in dairy herds. This prospective randomised clinical study assessed whether subcutaneous injection of 5.5 mL of TMS (40 mg zinc, 10 mg manganese, 5 mg selenium, 15 mg copper per mL), 14-28 days before planned start of calving (PSC) reduced clinical mastitis (CM), subclinical mastitis (SCM) and purulent vaginal discharge (PVD). From four farms, half of 1700 cows stratified on somatic cell count, age and breed were randomly allocated to treatment or no treatment. Occurrence of CM from - 7 to PSC + 100 days, SCM at PSC + 60 days and PVD at PSC + 24 days was analysed using survival analysis and Bayesian generalised mixed multivariable models. From -7 to PSC +30 days, TMS reduced the adjusted hazard ratio (HR) for CM at quarter and cow level (P < 0.001), with no evidence for an effect beyond 30 days. The adjusted OR (and 95% highest density interval, HDI) for the effect of TMS on CM from -7 to PSC +30 days was 0.40 (95% HDI, 0.26-0.63) at quarter level, 0.51 (95% HDI, 0.38-0.69) at cow level and for SCM, 0.72 (95% HDI, 0.54-0.95). The difference in CM incidence from TMS at the cow level was -2.0% (95% HDI, -3.4 to -1.1%) and -1.2% (95% HDI, -3.2 to - 0.6%) at quarter level. No clear effect was identified of TMS on cumulative incidence of PVD.

RESUMO

BACKGROUND: Cancer survivors over the age of 65 have unique needs due to the higher prevalence of functional and cognitive impairment, comorbidities, geriatric syndromes, and greater need for social support after chemotherapy. In this study, we will evaluate whether a Geriatric Evaluation and Management-Survivorship (GEMS) intervention improves functional outcomes important to older cancer survivors following chemotherapy. METHODS: A cluster-randomized trial will be conducted in approximately 30 community oncology practices affiliated with the University of Rochester Cancer Center (URCC) National Cancer Institute Community Oncology Research Program (NCORP) Research Base. Participating sites will be randomized to the GEMS intervention, which includes Advanced Practice Practitioner (APP)-directed geriatric evaluation and management (GEM), and Survivorship Health Education (SHE) that is combined with Exercise for Cancer Patients (EXCAP©®), or usual care. Cancer survivors will be recruited from community oncology practices (of participating oncology physicians and APPs) after the enrolled clinicians have consented and completed a baseline survey. We will enroll 780 cancer survivors aged 65 years and older who have completed curative-intent chemotherapy for a solid tumor malignancy within four weeks of study enrollment. Cancer survivors will be asked to choose one caregiver to also participate for a total up to 780 caregivers. The primary aim is to compare the effectiveness of GEMS for improving patient-reported physical function at six months. The secondary aim is to compare effectiveness of GEMS for improving patient-reported cognitive function at six months. Tertiary aims include comparing the effectiveness of GEMS for improving: 1) Patient-reported physical function at twelve months; 2) objectively assessed physical function at six and twelve months; and 3) patient-reported cognitive function at twelve months and objectively assessed cognitive function at six and twelve months. Exploratory health care aims include: 1) Survivor satisfaction with care, 2) APP communication with primary care physicians (PCPs), 3) completion of referral appointments, and 4) hospitalizations at six and twelve months. Exploratory caregiver aims include: 1) Caregiver distress; 2) caregiver quality of life; 3) caregiver burden; and 4) satisfaction with patient care at six and twelve months. DISCUSSION: If successful, GEMS would be an option for a standardized APP-led survivorship care intervention. TRIAL REGISTRATION: ClinicalTrials.govNCT05006482, registered on August 9, 2021.

RESUMO

AIMS: Current follow-up for head and neck cancer (HNC) is ineffective, expensive and fails to address patients' needs. The PETNECK2 trial will compare a new model of patient-initiated follow-up (PIFU) with routine scheduled follow-up. This article reports UK clinicians' views about HNC follow-up and PIFU, to inform the trial design. MATERIALS AND METHODS: Online focus groups with surgeons (ear, nose and throat/maxillofacial), oncologists, clinical nurse specialists and allied health professionals. Clinicians were recruited from professional bodies, mailing lists and personal contacts. Focus groups explored views on current follow-up and acceptability of the proposed PIFU intervention and randomised controlled trial design (presented by the study co-chief investigator), preferences, margins of equipoise, potential organisational barriers and thoughts about the content and format of PIFU. Data were interpreted using inductive thematic analysis. RESULTS: Eight focus groups with 34 clinicians were conducted. Clinicians highlighted already known limitations with HNC follow-up - lack of flexibility to address the wide-ranging needs of HNC patients, expense and lack of evidence - and agreed that follow-up needs to change. They were enthusiastic about the PETNECK2 trial to develop and evaluate PIFU but had concerns that PIFU may not suit disengaged patients and may aggravate patient anxiety/fear of recurrence and delay detection of recurrence. Anticipated issues with implementation included ensuring a reliable route back to clinic and workload burden on nurses and allied health professionals. CONCLUSIONS: Clinicians supported the evaluation of PIFU but voiced concerns about barriers to help-seeking. An emphasis on patient engagement, psychosocial issues, symptom reporting and reliable, quick routes back to clinic will be important. Certain patient groups may be less suited to PIFU, which will be evaluated in the trial. Early, meaningful, ongoing engagement with clinical teams and managers around the trial rationale and recruitment process will be important to discourage selective recruitment and address risk-averse behaviour and potential workload burden.

RESUMO

INTRODUCTION: Organs procured following brain stem death (BSD) are the main source of organ grafts for transplantation. However, BSD is associated with inflammatory responses that may damage the organ and affect both the quantity and quality of organs available for transplant. Therefore, we aimed to investigate plasma and bronchoalveolar lavage (BAL) pro-inflammatory cytokine profiles and cardiovascular physiology in a clinically relevant 6-h ovine model of BSD. METHODS: Twelve healthy female sheep (37-42 Kg) were anaesthetized and mechanically ventilated prior to undergoing BSD induction and then monitored for 6 h. Plasma and BAL endothelin-1 and cytokines (IL-1ß, 6, 8 and tumour necrosis factor alpha (TNF-α)) were assessed by ELISA. Differential white blood cell counts were performed. Cardiac function during BSD was also examined using echocardiography, and cardiac biomarkers (A-type natriuretic peptide and troponin I were measured in plasma. RESULTS: Plasma concentrations big ET-1, IL-6, IL-8, TNF-α and BAL IL-8 were significantly (p < 0.01) increased over baseline at 6 h post-BSD. Increased numbers of neutrophils were observed in the whole blood (3.1 × 109 cells/L [95% confidence interval (CI) 2.06-4.14] vs. 6 × 109 cells/L [95%CI 3.92-7.97]; p < 0.01) and BAL (4.5 × 109 cells/L [95%CI 0.41-9.41] vs. 26 [95%CI 12.29-39.80]; p = 0.03) after 6 h of BSD induction vs baseline. A significant increase in ANP production (20.28 pM [95%CI 16.18-24.37] vs. 78.68 pM [95%CI 53.16-104.21]; p < 0.0001) and cTnI release (0.039 ng/mL vs. 4.26 [95%CI 2.69-5.83] ng/mL; p < 0.0001), associated with a significant reduction in heart contractile function, were observed between baseline and 6 h. CONCLUSIONS: BSD induced systemic pro-inflammatory responses, characterized by increased neutrophil infiltration and cytokine production in the circulation and BAL fluid, and associated with reduced heart contractile function in ovine model of BSD.

RESUMO

The emergence of the COVID-19 pandemic has severely affected medical treatment protocols throughout the world. While the pandemic does not affect hand surgeons at first glance, they have a role to play. The purpose of this study was to describe the different measures that have been put in place in response to the COVID-19 pandemic by hand surgeons throughout the world. The survey comprised 47 surgeons working in 34 countries who responded to an online questionnaire. We found that the protocols varied in terms of visitors, health professionals in the operating room, patient waiting areas, wards and emergency rooms. Based on these preliminary findings, an international consensus on hand surgery practices for the current viral pandemic, and future ones, needs to be built rapidly.

RESUMO

BACKGROUND: One of the most important parameters that must be obtained when resuscitating a critically ill or injured paediatric patient is their weight. The best known paediatric weight estimation system is arguably the Broselow Tape, but the tape has been shown to be very inaccurate. The aim of this study was to determine and compare the accuracy of the Broselow tape, a modified Broselow tape system, the PAWPER XL tape and the hanging leg weight technique for potential utilisation in the paediatric resuscitation setting. METHOD: A convenience sample of 200 children between the ages of 1 month and 16 years were enrolled. All the children's weights were estimated using the Broselow tape, a habitus-modified Broselow tape system, the PAWPER XL tape and the hanging leg weight technique. Overall accuracy was evaluated using the percentage of weight estimations falling within 10% of actual weight (PW10). RESULTS: The PAWPER XL tape performed the best, whilst the hanging leg weight technique performed the poorest with PW10s of 74% and 19.5%, respectively. The Broselow tape with and without habitus-modification only showed modest accuracy, with PW10s of 61.7% and 59.1% respectively. CONCLUSION: The PAWPER XL tape performed significantly better than other weight estimation systems and is most appropriate for use in South African paediatric emergencies. The habitus-modified Broselow system produced only modest improvement in overall weight estimation accuracy of the Broselow tape.

RESUMO

The aim of this research was to develop a tool to identify and assess the qualities of cancer-related loneliness in adult cancer survivors who have completed treatment. In addition to reporting the development of the tool, we explicate the process of using the findings of a qualitative analysis to generate questionnaire items, as currently little guidance exists on this topic. The findings of our qualitative research exploring the experience of loneliness in adult cancer survivors who had completed treatment, together with the findings of our concept analysis of loneliness, were used to develop an assessment tool for cancer-related loneliness following treatment completion. Cognitive testing was undertaken to assess fidelity of comprehension and feasibility in administration. The Cancer-Related Loneliness Assessment Tool is a 10-item self-report questionnaire capturing the essential elements of cancer-related loneliness following treatment completion. Experts believed the questionnaire to be face-valid and usable in clinical practice, and preliminary cognitive testing indicated that the items generate the information intended and individuals have little trouble completing the tool. Following further development work, the tool could be employed to identify cancer-related loneliness following treatment completion. It could also aid with the development/adaptation and evaluation of person-centred interventions to address such loneliness.

RESUMO

PURPOSE: Patients diagnosed with laryngeal cancer and their families face unique challenges. Providing information is an essential component of care. However little is known about the way in which they use information. This study aims to explore the different types of information used by laryngeal cancer patients and their carers from diagnosis into the follow up phase. METHOD: The study adopted an interpretive longitudinal design using qualitative interviews at two specific time points. Twenty laryngeal cancer patients and 17 carers were interviewed. Data were analysed using Framework Analysis. RESULT: Two main categories of information: professional and experiential, were found to be used, drawn from a range of sources. The information received at diagnosis appeared to contribute to an 'illusion of certainty' that life would return to normal at the end of treatment. However, as patients progressed into follow-up, many were propelled into a 'reality of uncertainty' due to the "disconnect" between the expectations both patient and carer developed from information received over the cancer trajectory. CONCLUSION: The findings from this longitudinal study suggest that people affected by laryngeal cancer use two broad categories of information derived from a range of different sources and influenced by their own experiences. Health professionals need to situate information in the context of the individual's understanding and prior knowledge of health and illness to help generate more realistic expectations of treatment outcomes. The level of uncertainty experienced by both patients and their carers after treatment suggests a clear need for continued supportive care.

RESUMO

The aim of this study was to identify the distress, unmet needs and concerns of head and neck cancer (HNC) survivors in the first 5 years after treatment. Two hundred and eighty HNC survivors from three Scottish health boards responded to a cross-sectional postal survey in 2011. Questionnaires included the Distress Thermometer, Patient Concerns Inventory (PCI) and an adapted version of the PCI to measure unmet needs. One-third of the survivors had moderate or severe levels of distress, and 74% had at least one unmet need. The most common concerns and unmet needs included oral and eating problems, fear of recurrence and fatigue. Multivariate analysis revealed that being younger, out of work (not retired), ever having had a feeding tube fitted, having a greater number of comorbidities and living alone were associated with higher levels of distress, concerns and unmet needs. The diversity of concerns and unmet needs identified in this study highlights the importance of holistic needs assessment as part of follow-up care for HNC survivors with tailoring of support for particular concerns. Specific information resources and self-management strategies are required to help HNC survivors with the practical and functional consequences of HNC treatment.

RESUMO

Patterns of follow-up and survivorship care are changing in response to growing numbers of cancer survivors and an increasing recognition that traditional models are unsustainable and result in unmet needs. Clinicians have shown reluctance in changing conventional follow-up practices for patients with head and neck cancer. This study aimed to explore nurses' and allied health professionals' views and practices in relation to follow-up, holistic needs assessment and survivorship care in this patient group. An online survey of members of the British Association of Head and Neck Oncology Nurses was undertaken. The response rate was 43% (74 of 174). Findings revealed a range of existing models of follow-up, rehabilitation and support for people with head and neck cancer across the UK. Specialist staff were open to new models of care and to more responsibility, with adequate training and supervision. There were some gaps in the provision of comprehensive survivorship care and some specific areas of practice in which nurses lacked confidence, knowledge and skills, such as managing medications and complex symptoms. Further research is needed to develop and evaluate effective models of follow-up and support for a growing population of head and neck cancer survivors who have diverse and complex needs.

RESUMO

BACKGROUND: Roux-en-Y choledochojejunostomy and duct-to-duct anastomosis are potential methods for biliary reconstruction in liver transplantation (LT) for recipients with primary sclerosing cholangitis (PSC). However, there is controversy over which method yields superior outcomes. The purpose of this study was to evaluate the outcomes of duct-to-duct versus Roux-en-Y biliary anastomosis in patients undergoing LT for PSC. METHODS: Studies comparing Roux-en-Y versus duct-to-duct anastomosis during LT for PSC were identified based on systematic searches of 9 electronic databases and multiple sources of gray literature. RESULTS: The search identified 496 citations, including 7 retrospective series, and 692 patients met eligibility criteria. The use of duct-to-duct anastomosis was not associated with a significant difference in clinical outcomes, including 1-year recipient survival rates (odds ratio [OR], 1.02; 95% confidence interval [CI], 0.65-1.60; P = .95), 1-year graft survival rates (OR, 1.11; 95% CI, 0.72-1.71; P = .64), risk of biliary leaks (OR, 1.23; 95% CI, 0.59-2.59; P = .33), risk of biliary strictures (OR, 1.99; 95% CI, 0.98-4.06; P = .06), or rate of recurrence of PSC (OR, 0.94; 95% CI, 0.19-4.78; P = .94). CONCLUSIONS: There were no significant differences in 1-year recipient survival, 1-year graft survival, risk of biliary complications, and PSC recurrence between Roux-en-Y and duct-to-duct biliary anastomosis in LT for PSC.

RESUMO

AIM: This study aimed to assess colorectal clinicians' knowledge and understanding about the risks and benefits of weight management, to document current practice and to identify perceived barriers to providing lifestyle advice to colorectal cancer survivors. METHOD: Questionnaires were sent to 768 clinicians (doctors and nurses) working in colorectal cancer, identified from professional databases. These data were complemented by in-depth interviews exploring opportunities for and barriers to giving lifestyle advice. RESULTS: A total of 323 replies were received (42% response rate) and 20 respondents completed in-depth interviews. Half (52%) reported that they were familiar with guidance for lifestyle advice for cancer survivors. Most (77%) thought reducing weight was important for improving the health of those who were overweight and 75% thought it appropriate to offer lifestyle advice to people with body mass index over 30 kg/m(2) . Half (50%) reported that weight reduction was an important service priority for normal clinical practice. Half (50%) of respondents said that they would value additional training in this area. Interview data revealed that current practice is influenced by the lack of evidence for the impact of weight management and a belief that 'weight gain is good and weight loss bad' in the cancer setting. Patient sensitivity, time available, role constraints and lack of skills in weight management were also factors. CONCLUSION: There is an awareness of the importance of weight management amongst colorectal cancer clinicians and some indication of advice being provided. However, current perceptions, knowledge and skills suggest scope for further training.

RESUMO

CONTEXT: Histologic examination of clinically suspicious melanocytic lesions is very sensitive and specific for the detection of malignant melanoma. Yet, the malignant potential of a small percentage of melanocytic lesions remains histologically uncertain. Molecular testing offers the potential to detect the genetic alterations that lead to malignant behavior without overt histologic evidence of malignancy. OBJECTIVE: To differentiate benign melanocytic nevi from malignant melanoma and to predict the clinical course of melanocytic lesions with ambiguous histology using a novel genomic microarray. DESIGN: We applied a newly developed single-nucleotide polymorphism genomic microarray to formalin-fixed, paraffin-embedded melanocytic lesions to differentiate benign nevi (n  =  23) from malignant melanoma (n  =  30) and to predict the clinical course of a set of histologically ambiguous melanocytic lesions (n  =  11). RESULTS: For cases with unambiguous histology, there was excellent sensitivity and specificity for identifying malignant melanoma with this genomic microarray (89% sensitivity, 100% specificity). For cases with ambiguous histology, the performance of this genomic microarray was less impressive. CONCLUSIONS: Without microdissection and with quantities of DNA one-tenth what is required for more commonly used microarrays, this microarray can differentiate between malignant melanoma and benign melanocytic nevi. For histologically ambiguous lesions, longer clinical follow-up is needed to confidently determine the sensitivity and specificity of this microarray. Some of the previous technical hurdles to the clinical application of genomic microarray technology are being overcome, and the advantages over targeted fluorescence in situ hybridization assays currently in clinical use are becoming apparent.

RESUMO

BACKGROUND: Few epidemiological studies have prospectively investigated preoperative and surgical risk factors for acute postoperative pain after surgery for breast cancer. We investigated demographic, psychological, pain-related and surgical risk factors in women undergoing resectional surgery for breast cancer. METHODS: Primary outcomes were pain severity, at rest (PAR) and movement-evoked pain (MEP), in the first postoperative week. RESULTS: In 338 women undergoing surgery, those with chronic preoperative pain were three times more likely to report moderate to severe MEP after breast cancer surgery (OR 3.18, 95% CI 1.45-6.99). Increased psychological 'robustness', a composite variable representing positive affect and dispositional optimism, was associated with lower intensity acute postoperative PAR (OR 0.63, 95% CI 0.48-0.82) and MEP (OR 0.71, 95% CI 0.54-0.93). Sentinel lymph node biopsy (SLNB) and intraoperative nerve division were associated with reduced postoperative pain. No relationship was found between preoperative neuropathic pain and acute pain outcomes; altered sensations and numbness postoperatively were more common after axillary sample or clearance compared with SLNB. CONCLUSION: Chronic preoperative pain, axillary surgery and psychological robustness significantly predicted acute pain outcomes after surgery for breast cancer. Preoperative identification and targeted intervention of subgroups at risk could enhance the recovery trajectory in cancer survivors.

RESUMO

Early diagnosis of mycosis fungoides (MF) is one of the most challenging problems in dermatopathology, as the histopathologic features of inflammatory dermatoses and MF may show significant overlap. One criterion used to distinguish early MF (patch stage) from dermatitis, which may be currently underutilized, is the presence of eosinophils. A search was performed for cases with a preoperative diagnosis of MF, cutaneous T-cell lymphoma, or dermatitis, which included 29 cases "diagnostic" for MF, 25 cases "suspicious" for MF, and 55 cases of spongiotic dermatitis. We examined tissue sections blinded to diagnosis to obtain an exact eosinophil count. Twenty-nine cases were diagnostic for MF (12 patch, 9 plaque, and 8 tumor stage). The average eosinophil count for cases diagnostic for patch stage MF was 1 eosinophil in 10 (0.11) sections examined. For plaque MF, there was 1 eosinophil in 5 (0.24) sections examined. All tumor stage MF cases showed abundant eosinophils within each section. Twenty-five cases were suspicious for MF (15 patches, 9 plaques, and 1 folliculotropic). The average eosinophil count for the patch lesions was 1 eosinophil in 4 (0.25) sections examined and 2 eosinophils per section for plaque lesions. Forty-five of 55 cases of spongiotic dermatitis had at least scattered eosinophils (>3) in each section. Twenty-three (47%) had eosinophils around most postcapillary venules. Only 3 of 45 patients (6.6%) with biopsies diagnostic or suspicious for patch or plaque stage MF showed >3 eosinophils per tissue section, whereas 45 of 55 (81.8%) biopsies of spongiotic dermatitis had >3. The presence of eosinophils (>3 per tissue section) is statistically significant in differentiating cases diagnostic or suspicious for patch or plaque stage MF from dermatitis (P < 0.0001). Our data indicate that eosinophils are uncommon in cases of patch and plaque MF. When a pathologist is faced with evaluating a biopsy that lacks some of the criteria used to make the diagnosis of patch stage MF, yet demonstrates >3 eosinophils per tissue section, dermatitis is the likely diagnosis. However, in cases where fewer than 3 eosinophils are present in sections, patch stage MF cannot be excluded.

RESUMO

Adipokinetic hormones are peptide hormones that mobilize lipids and/or carbohydrates for flight in adult insects and activate glycogen Phosphorylase in larvae during starvation and during molt. We previously examined the functional roles of adipokinetic hormone in Manduca sexta L. (Lepidoptera: Sphingidae). Here we report the cloning of the full-length cDNA encoding the putative adipokinetic hormone receptor from the fat body of M. sexta. The sequence analysis shows that the deduced amino acid sequence shares common motifs of G protein-coupled receptors, by having seven hydrophobic transmembrane segments. We examined the mRNA expression pattern of the adipokinetic hormone receptor by quantitative Real-Time PCR in fat body during development and in different tissues and found the strongest expression in fat body of larvae two days after molt to the fifth instar. We discuss these results in relation to some of our earlier results. We also compare the M. sexta adipokinetic hormone receptor with the known adipokinetic hormone receptors of other insects and with gonadotropin releasing hormone-like receptors of invertebrates.

RESUMO

Postmenopausal women with localised, early breast cancer (n = 285) were enrolled in a prospective subprotocol of the 'arimidex, tamoxifen, alone or in combination' (ATAC) trial to assess gynaecological abnormalities arising during treatment with anastrozole (1 mg/day) or tamoxifen (20 mg/day). After 6 years' follow-up, there appeared to be non-significantly fewer endometrial abnormalities with anastrozole than with tamoxifen (12.4% vs 20.2%, odds ratio 0.52; 95% confidence intervals 0.20, 1.32; p = 0.17). The time to first endometrial abnormality was non-significantly longer for patients receiving anastrozole compared with tamoxifen (hazard ratio 0.57; 95% confidence intervals 0.26, 1.22; p = 0.15), with most abnormalities occurring within the first year of treatment. Fewer patients treated with anastrozole appeared to require medical intervention for endometrial abnormalities, compared with patients on tamoxifen. This study showed that there was no significant difference in endometrial pathology between anastrozole and tamoxifen treatment groups.

RESUMO

BACKGROUND: We aimed to assess anxiety and the psychological impact of routine surveillance scans in long-term survivors of adult aggressive lymphoma. PATIENTS AND METHODS: In this cross-sectional observational study of 70 survivors of curable adult aggressive lymphoma, we measured anxiety and the doctor-patient relationship and performed a qualitative interview (n = 30) focused on patient perception of routine follow-up imaging studies. RESULTS: Participants were diagnosed with aggressive lymphoma a median of 4.9 years (2.4-38.0 years) before enrollment. Thirty-seven percent of patients were found to meet criteria for clinically significant anxiety, which was not associated with years since diagnosis. In multivariate analysis, history of relapse and a worse doctor-patient relationship were independently associated with higher anxiety levels. Despite representing a largely cured population, in qualitative interviews patients reported fear of recurrence as a major concern and considerable anxiety around the time of a follow-up imaging scan. CONCLUSIONS: Routine surveillance scans exacerbate underlying anxiety symptoms and fear of recurrence in survivors of aggressive lymphoma. Strategies to minimize follow-up imaging and to improve doctor-patient communication should be prospectively evaluated to address these clinically significant issues.

RESUMO

Bladder symptoms in multiple sclerosis (MS) are common and distressing but also highly amenable to treatment. A meeting of stakeholders involved in patients' continence care, including neurologists, urologists, primary care, MS nurses and nursing groups was recently convened to formulate a UK consensus for management. National Institute for Health and Clinical Excellence (NICE) criteria were used for producing recommendations based on a review of the literature and expert opinion. It was agreed that in the majority of cases, successful management could be based on a simple algorithm which includes using reagent sticks to test for urine infection and measurement of the post micturition residual urine volume. This is in contrast with published guidelines from other countries which recommend cystometry. Throughout the course of their disease, patients should be offered appropriate management options for treatment of incontinence, the mainstay of which is antimuscarinic medications, in combination, if necessary, with clean intermittent self-catheterisation. The evidence for other measures, including physiotherapy, alternative strategies aimed at improving bladder emptying, other medications and detrusor injections of botulinum toxin A was reviewed. The management of urinary tract infections as well as the bladder problems as part of severe disability were discussed and recommendations agreed.
