RESUMO

Follicular lymphomas are the most common of the clinically indolent non-Hodgkin lymphomas. The immunophenotypic pattern of follicular lymphoma classically demonstrates the B-cell markers CD19, CD20, CD22, CD79a, surface immunoglobulin and CD10. The tumour cells are usually negative for CD5. We described two cases of CD5-positive follicular lymphoma. This finding has rarely been described. Our aim was to discuss two cases of CD5-positive follicular lymphoma and review the published literature on the significance of CD5 expression. Bone marrow biopsies showing involvement with follicular lymphoma at our institution over the past 34 months were evaluated for the presence of CD5 positivity by flow cytometry and immunohistochemistry. Two of eight cases (25%) of the follicular lymphomas with marrow involvement at our institution were found to be CD5-positive. Only 36 cases of CD5-positive follicular lymphoma have previously been described in the literature. The clinical and therapeutic significance of this remains uncertain. More research into such cases may establish whether the presence of this aberrant marker bears prognostic significance.

RESUMO

BACKGROUND: The benefits of physical activity for reducing obesity and related chronic diseases are well known. The need for more family-based interventions to increase physical activity is frequently cited in the literature; however, little is known about if and how families are physically active together, and what factors might influence family-based participation in regular physical activity. This study examined the types of activities (physical and sedentary) engaged in as a family and explored parents' perceptions of the importance, frequency, nature and barriers to family physical activity. METHODS: Semi-structured telephone interviews were conducted with 30 parents (26 female, four male) of 10- to 11-year-old schoolchildren who attended either low, middle or high socio-economic status schools in Bristol, UK. Interviews were transcribed verbatim, anonymized and analysed using conventional content analysis. RESULTS: The majority of parents rated family engagement in physical activity as important, and identified benefits such as increased parent-child communication, spending time together, enjoyment, enhanced mental health, weight control and physical fitness. Despite these benefits most parents reported their families did little or no physical activity together as a family unit during the week, and any activities performed together were usually sedentary in nature. They reported increased family physical activity on the weekends but rarely including the full family unit simultaneously. Parents in two-parent households commonly paired off with one or more children because of complexities of schedules. Commonly reported barriers were busy lifestyles, diverse ages and interests of children and adults, bad weather, and lack of access to facilities, transportation and money to support activities. CONCLUSIONS: Family-based interventions might be more effective if they are designed to accommodate the complex demands and needs of two-parent and single-parent families and provide affordable, diverse activities appealing to a wide range of interests.

RESUMO

The dramatic variation in the composition of a brine pond in Antarctica is a seasonal phenomenon. The phase relations of salts in solution are such that hydrologic conditions and temperature determine composition during the austral summer. Temperature is the primary determinant of composition during the winter.

RESUMO

Advanced glycosylation end products (AGEs) form spontaneously from glucose-derived Amadori products and accumulate on long-lived tissue proteins. AGEs have been implicated in the pathogenesis of several of the complications of aging and diabetes, including atherosclerosis and renal disease. With the use of recently developed AGE-specific antibodies, an AGE-modified form of human hemoglobin has been identified. Termed hemoglobin-AGE (Hb-AGE), this modified species accounts for 0.42 percent of circulating hemoglobin in normal individuals but increases to 0.75 percent in patients with diabetes-induced hyperglycemia. In a group of diabetic patients treated with the advanced glycosylation inhibitor aminoguanidine, Hb-AGE levels decreased significantly over a 1-month period. Hemoglobin-AGE measurements may provide an index of long-term tissue modification by AGEs and prove useful in assessing the contribution of advanced glycosylation to a variety of diabetic and age-related complications.

RESUMO

OBJECTIVES: Outpatient parenteral antimicrobial therapy (OPAT) is increasingly used to treat a wide range of infections. However, there is risk of hospital readmissions. The study aim was to develop a prediction model for the risk of 30-day unplanned hospitalization in patients receiving OPAT. METHODS: Using a retrospective cohort design, we retrieved data on 1073 patients who received OPAT over 2 years (January 2015 to January 2017) at a large teaching hospital in Sheffield, UK. We developed a multivariable logistic regression model for 30-day unplanned hospitalization, assessed its discrimination and calibration abilities, and internally them validated using bootstrap resampling. RESULTS: The 30-day unplanned hospitalization rate was 11% (123/1073). The main indication for hospitalization was worsening or nonresponse of infection (52/123, 42%). The final regression model consisted of age (adjusted odds ratio (aOR), 1.18 per decade; 95% confidence interval (CI), 1.04-1.34), Charlson comorbidity score (aOR, 1.11 per unit increase; 95% CI, 1.00-1.23), prior hospitalizations in past 12 months (aOR, 1.30 per admission; 95% CI, 1.17-1.45), concurrent intravenous antimicrobial therapy (aOR, 1.89; 95% CI, 1.03-3.47) and endovascular infection (aOR, 3.51; 95% CI, 1.49-8.28). Mode of OPAT treatment was retained in the model as a confounder. The model had adequate concordance (c-statistic 0.72; 95% CI 0.67-0.77) and calibration (Hosmer-Lemeshow p 0.546; calibration slope 0.99; 95% CI 0.78-1.21), and low degree of optimism (bootstrap optimism corrected c-statistic, 0.70). CONCLUSIONS: We identified a set of six important predictors of unplanned hospitalization based on readily available data. The prediction model may help improve OPAT outcomes through better identification of high-risk patients and provision of tailored care.

RESUMO

BACKGROUND: Most adults with bacterial meningitis and meningococcal septicaemia present to junior doctors who have limited experience of these conditions. In contrast to paediatric practice, data from industrialized countries with regard to current hospital management practice are lacking. AIM: To examine whether current practice meets recommended standards in hospital management of community-acquired bacterial meningitis and meningococcal septicaemia among adults. DESIGN: National audit of medical records. METHODS: We conducted a survey of all patients with acute bacterial meningitis and meningococcal septicaemia admitted to 18 randomly selected acute hospitals in England and Wales between 1 January 2000 and 31 December 2001. All stages of care, including pre-hospital management, initial hospital assessment, record keeping, and ongoing hospital and public health management, were assessed. RESULTS: We identified 212 cases of bacterial meningitis and meningococcal septicaemia; 190 cases remained in the final analysis. Clinical record keeping did not meet acceptable standards in 33% of cases. Parenteral antibiotics were given within 1 h of hospital arrival in 56% of cases, increasing to 79% among those with an initial differential diagnosis that included bacterial meningitis or meningococcal septicaemia. A full severity of illness assessment was made in 27%. The quality of clinical practice varied widely between hospitals. This was most pronounced in the timeliness of consultant review (p < 0.0005). DISCUSSION: The quality of adult clinical practice for bacterial meningitis and meningococcal septicaemia needs improvement. This study provides a tool for developing targeted interventions to improve quality of care and outcome among adults with life-threatening infections, both in the UK and in other countries.

RESUMO

BACKGROUND: Risks to the mental health of children and families exposed to conflict in Syria are of such magnitude that research identifying how best to deliver psychological first aid is urgently required. This study tested the feasibility of a novel approach to large-scale distribution of information and data collection. METHODS: Routine humanitarian deliveries of bread by a bakery run by a non-governmental organisation (NGO) were used to distribute parenting information leaflets and questionnaires to adults looking after children in conflict zones inside Syria. Study materials were emailed to a project worker in Turkey. Leaflets and questionnaires requesting feedback were transported alongside supplies to a bakery in Syria, and then packed with flatbreads. Three thousand bread-packs were distributed, from three distribution points to which questionnaires were returned, and then taken to Turkey and dispatched to the UK. FINDINGS: Notwithstanding delays, 3000 leaflets and questionnaires were successfully distributed over 2 days. Questionnaire return yielded 1783 responses, a 59.5% return rate. Overall ratings of the usefulness of the leaflet were 1060 (59.5%) 'quite a lot' and 339 (19.0%) 'a great deal'. Content analysis was used to code 400 respondent comments. Four themes emerged; positive comments about the leaflet, suggestions for modifications, descriptions of children's needs and the value respondents placed on faith. INTERPRETATION: Findings indicate the willingness of NGO staff and volunteers to assist in research, the remarkable willingness of caregivers to respond and the value of brief advice. It demonstrates the scope for using existing humanitarian routes to distribute information and receive feedback even in high-risk settings.

RESUMO

Three hundred twenty-five women with metastatic adenocarcinoma of the breast who had failed one prior chemotherapeutic regimen for advanced disease were randomized to receive 14 mg/m2 of mitoxantrone or 75 mg/m2 of doxorubicin intravenously (IV) every 3 weeks. Enrollment was closed on October 31, 1984, after 165 patients were randomized to mitoxantrone and 160 patients to doxorubicin. Patients randomized to the two treatment groups were compared for response rate, duration of response, time to progression or death, time to treatment failure (TTF), and survival. The response rate to mitoxantrone was 20.6%, to doxorubicin 29.3% (P = .07). The median response duration was 151 days for the mitoxantrone group and 126 days for the doxorubicin group (P = .16). The median TTF was 70 days in the mitoxantrone group and 104 days in the doxorubicin group (P = .36). The median survival of patients initially randomized to receive mitoxantrone was 273 days; for doxorubicin 268 days (P = .40). There were three responses among 77 patients crossed over to mitoxantrone after initial treatment with doxorubicin. The major dose-limiting toxicity for both drugs was leukopenia. There was significantly less severe and less frequent toxicity with mitoxantrone administration. Severe nausea and vomiting occurred in 9.5% of mitoxantrone patients and 25.3% of doxorubicin patients (P less than .001). The incidence of severe stomatitis and mucositis was 0.6% in the mitoxantrone group and 8.4% in the doxorubicin group (P = .001). Severe alopecia occurred in 5.1% of mitoxantrone patients and 61.0% of doxorubicin patients (P less than .001). A life-table comparison of the cumulative dose to the development of a cardiac event showed that mitoxantrone had significantly less cardiotoxicity than doxorubicin (P = .0005). This study demonstrates that mitoxantrone is active as a single agent in the treatment of metastatic breast cancer. Compared with doxorubicin it appears to be marginally less active and significantly less toxic. We conclude that mitoxantrone can be used alone or with other standard drugs to palliate the symptoms of metastatic breast cancer, especially in settings where drug toxicity is an important consideration.

RESUMO

Three hundred thirty-one women with metastatic breast cancer were randomized to receive combination chemotherapy with either cyclophosphamide, Novantrone (mitoxantrone; Lederle Laboratories, Wayne, NJ), and fluorouracil (CNF) or cyclophosphamide, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and fluorouracil (CAF). Patients could not have had prior chemotherapy, although adjuvant chemotherapy was acceptable. Initial doses were 500 mg/m2 of cyclophosphamide and 500 mg/m2 of fluorouracil with either 10 mg/m2 of mitoxantrone or 50 mg/m2 of doxorubicin, administered intravenously (IV) on day 1 and repeated every 3 weeks. There were no statistically significant differences in pretreatment or prior therapy characteristics between the groups. For patients assigned to the CNF and CAF groups, respectively, 25 (18%) were premenopausal, 39 (40%) were estrogen receptor (ER) negative, 39 (38%) had a disease-free interval less than 1 year, and 24 (26%) had received prior adjuvant chemotherapy. All patients were compared for response rate, duration of response, time to progression or death, time to treatment failure (TTF), and survival. None of these parameters were statistically significant favoring one regimen over the other. The response rate (complete [CR] and partial response [PR]) was 29% for the CNF group (95% confidence interval of 22% to 37%) and 37% for the CAF group (95% confidence interval of 29% to 45%). The median response duration and TTF were 171 days and 125 days for the CNF group and 254 days and 147 days for the CAF group, respectively. The median survival times for the CNF group and the CAF group were 377 and 385 days, respectively. The major dose-limiting toxicity for both regimens was leukopenia, manifested as granulocytopenia. The incidence of stomatitis/mucositis was 10% in the CNF group and 19% in the CAF group. Alopecia occurred in 49% of CNF patients (severely for 4%) and in 86% of CAF patients (severely for 39%). Nausea/vomiting occurred in 80% of CNF patients and in 81% of CAF patients; the degree of severity was also comparable. There was significantly less cardiotoxicity observed in the CNF group compared with the CAF group. Although CNF is somewhat less effective in overall response rate, survival curves are identical. CNF can be offered to patients who reject anthracycline-containing regimens because of fear of alopecia.

RESUMO

This phase III, randomized trial in previously untreated adults with ANLL compared mitoxantrone plus cytosine arabinoside with the CALGB "7 + 3" daunorubicin-based regimen. Two hundred evaluable patients (98 treated with the mitoxantrone-based regimen and 102 with the daunorubicin-based regimen) were included in the analysis of efficacy. The median age of the patients was 60 years. The induction regimen comprised cytosine arabinoside 100 mg/m2 by infusion daily for 7 days and mitoxantrone 12 mg/m2 or daunorubicin 45 mg/m2 daily for days 1-3. If needed, a second induction course was administered: cytosine arabinoside for 5 days and mitoxantrone or daunorubicin for 2 days. Postremission therapy consisted of two consolidation courses, identical to the second induction course. Sixty-three percent (62 of 98) of patients treated with mitoxantrone achieved complete remission (CR), compared to 53% (54 of 102) treated with daunorubicin. The median time to CR was 35 days in patients treated with mitoxantrone and 43 days for those treated with daunorubicin. Eighty-nine percent (55 of 62) of patients treated with mitoxantrone who entered complete remission achieved CR following one induction course, compared to 68% (37 of 54) of patients treated with daunorubicin who entered CR. The median duration of CR was 240 days in patients treated with mitoxantrone and 198 days in those treated with daunorubicin; the median length of survival was 328 days in patients who received mitoxantrone and 247 days in those who received daunorubicin. The toxicity profiles in patients treated with either of the two regimens were comparable in incidence and in severity. Patients treated with mitoxantrone required fewer median platelet units and were treated with fewer median days of intravenous antibiotics, compared to those who received daunorubicin. Mitoxantrone in combination with cytosine arabinoside is effective in previously untreated ANLL. complete remissions occur more frequently after a single induction course of the mitoxantrone-based regimen, compared to the standard Cancer and Acute Leukemia Group B regimen. This should be explored in further trials.

RESUMO

BACKGROUND: In the humanitarian crisis context of conflict zones, collecting data is essential for identifying and addressing the mental health needs of refugee children to avoid mass suffering. This study tested the feasibility of recruiting refugees caring for children and using established and brief parent-report questionnaires in a challenging context to collect mental health data on refugee children displaced by Syria's conflict. METHODS: Caregivers of 4-10-year olds attending primary schools run by non-governmental organisation (NGO) Generation Freedom in and near refugee camps on the Syrian-Turkish border were invited to complete the Pediatric Emotional Distress Scale (PEDS) and Strengths and Difficulties Questionnaire (SDQ). RESULTS: It was possible to reach 144 adult refugees caring for children with research participation information and use informed consent procedures. A total of 106 caregivers completed the questionnaires yielding a good return rate (74%). Eighty-two (77.4%) caregivers had complete data on the PEDS and 61 (57.5%) on the SDQ. Almost half (49%) of the children met the clinical cut-off for being anxious/withdrawn and 62% for being fearful rated using the PEDS and 45% for SDQ rated emotional symptoms. More than a third had clinical levels of behavioural problems on both scales. CONCLUSIONS: It proved feasible to collect child mental health data in challenging conditions in the context of the Syrian crisis with support from a local NGO providing humanitarian assistance. The PEDS performed better than the SDQ in this context. High levels of emotional distress and behavioural problems in children reiterate the urgent need for evidence-based psychosocial support.

RESUMO

The coenzyme Q (ubiquinone) concentrations of a number of tissues have been determined over the life span of the male laboratory rat. Coenzyme Q increased between 2 and 18 months and decreased significantly at 25 months in the heart and kidney, and the gastrocnemius, oblique and deep aspect (red) vastus lateralis muscles. The coenzyme Q concentration of liver increased over the life span, while it remained relatively constant in brain, lung, and the superficial aspect (white) of the vastus lateralis muscle. Data are also included for organ weights and protein contents of tissues over the life span. The various roles of coenzyme Q in cellular electron transfer and its regulation, energy conservation in oxidative phosphorylation, and its clinical efficacy in diseases of energy metabolism are discussed. It is hypothesized that coenzyme Q serves as a free radical quencher in the mitochondrion, a major site of free radical formation, in addition to its other roles in cellular energy metabolism, and that its cellular diminution may contribute to the loss of cellular function accompanying ageing.

RESUMO

Open surgical procedures for pleural empyema remain controversial in children. The pediatric literature generally recommends a prolonged trial of antibiotics and closed tube thoracostomy drainage. We report a favorable experience with a selective approach to open drainage in 22 children, many of whom had an empyema already organizing at admission. Open drainage was considered in children whose conditions failed to improve after 3 to 5 days of therapy with antibiotics and closed drainage. The method of drainage was selected according to the pathologic phase of the empyema: five children with fibrinopurulent empyema were successfully managed by limited decortication, and 17 with organizing empyema received decortication. Clinical improvement was usually dramatic; most of the children became afebrile by postoperative day 3 and were discharged by postoperative day 10. There were no deaths. Three children (14%) had complications of postoperative air leak or infection. Streptococcus pneumoniae (5) and Hemophilus influenzae (3) were the most common single pathogens. The presence of anaerobic bacteria in 8 of 22 children (36%) was associated with rapid organization of the empyema and the need for decortication. Decortication procedures have a low risk and are effective in children with empyema. They should be considered as definitive therapy, rather than as a last resort.

RESUMO

The clinical and laboratory safety of cefixime based on analysis of data from 1575 adults (1118 treated daily and 457 treated twice a day) and 615 children (299 treated daily and 316 treated twice a day) in studies of urinary tract and lower and upper respiratory tract infections (including otitis media) is reviewed. The incidence of adverse clinical experiences and occurrence of laboratory abnormalities were similar to those seen with other beta-lactam antimicrobial agents. Gastrointestinal side effects were the predominant adverse experiences seen in both daily and twice daily programs in adults and children. The incidence of gastrointestinal intolerance was not dependent upon the frequency of the dosage. Symptoms of drug hypersensitivity were infrequently reported. No serious chemical, hematologic or urologic abnormalities were noted. The data confirm the safety of cefiximine in both adults and children, whether it is administered once or twice a day.

RESUMO

BACKGROUND: Streptococcus pneumoniae is a major disease burden in young children and the incidence of antibiotic-resistant pneumococcal strains is increasing. Multivalent pneumococcal saccharide-protein conjugate vaccines have recently been developed. OBJECTIVES: To assess the immunogenicity and reactogenicity of a 7-valent pneumococcal conjugate vaccine (7VPnC) administered as a separate injection or as a combined injection with Haemophilus influenzae type b vaccine (HbOC) at 2, 3 and 4 months of age. METHODS: Randomized controlled trial of 368 healthy UK infants receiving routine vaccines only (control group), routine vaccines and 7VPnC as a separate injection (separate group), or routine vaccines and 7VPnC combined with HbOC (combined group) at 2, 3 and 4 months. The control group received 7VPnC at 5, 6 and 7 months. All groups received pneumococcal polysaccharide vaccine at 13 to 16 months. Anticapsular IgG antibodies to 7VPnC serotypes were measured at 2, 5, 13 and 14 months and safety data collected. RESULTS: IgG antibody concentrations at 5 months were higher in the two treatment groups compared with the controls for all 7VPnC serotypes (P < 0.001) and higher in the separate group than the combined group for five 7VPnC serotypes (P < 0.05). For both treatment groups antibody concentrations were higher at 14 months (range, 6.6 to 25.3 microg/ml) than at 5 months (range, 0.6 to 2.5 microg/ml) for all 7VPnC serotypes (P < 0.001). CONCLUSION: 7VPnC was well-tolerated, safe and immunogenic when administered as a separate or as a combined 7VPnC/HbOC injection. Although antibody responses were lower in the infants who received the combination compared with those who received 7VPnC as a separate injection, marked anamnestic responses to polysaccharide challenge were observed, suggesting that both groups were immunologically primed.

RESUMO

BACKGROUND: Invasive meningococcal disease, due to Neisseria meningitidis, is an important cause of morbidity and mortality in young children and adolescents. Nasopharyngeal carriage of meningococci (MC), is most prevalent in young adults whereas carriage of Neisseria lactamica (LC), a related non-pathogenic organism, is most prevalent in young children. The objective of this study was to use modelling techniques to test hypotheses on the processes that govern the incidence of meningococcal disease (MD). METHODS: Deterministic compartmental models were fitted to age structured data sets of MC, LC and MD. RESULTS: The model most consistent with the available data sets is one where LC inhibits MC, an inhibition that lasts for a mean of 4.7 years. The hypothesis that LC also acts as a natural immunogen against MD was consistent with this model. The second peak of MD observed among adolescents could be due to the peak in the acquisition of MC in this age group. CONCLUSIONS: The role of LC as a natural immunogen against asymptomatic and symptomatic meningococcal infection was consistent with available field data. If the introduction of novel meningococcal vaccines into a population changes the prevalence of MC or LC, this could have a substantial impact on the effectiveness of immunization programmes. This paper demonstrates the potential utility of modelling to estimate these effects.

RESUMO

AIMS: To document demography, changing workload patterns, job satisfaction, morale, and prevalence of stress and psychological morbidity among UK consultant medical microbiologists and virologists. METHOD: A questionnaire survey of all identified UK practising consultant medical microbiologists and virologists (n= 464). RESULTS: Among 367 respondents (79%), there were 33 virologists and at least 89 single handed consultants. Over half the respondents (58%) were working a 1 : 1 or 1 : 2 on call rota during the week and a similar proportion (51%) at weekends. Of all consultants (including those working part time), 56% were working more than 48 hours weekly. Working more than 48 hours weekly, and being on call 1 : 1 or 1 : 2 at weekends, were both independently associated with increased psychological morbidity. Those on call 1 : 1 or 1 : 2 at weekends were also more likely to have low or very low morale. Female consultants were more likely to have higher stress scores. More than half of the respondents (208 of 363; 57%) were making active financial provision to retire early, and 198 of 363 (55%) did not intend to work beyond the age of 60. CONCLUSIONS: The long hours worked by many consultant microbiologists and virologists are in breach of the European Working Time Directive and are associated with a higher degree of psychological morbidity. For most consultants, the frequency of on call commitments is demanding and job satisfaction and morale have deteriorated. Urgent action is needed, particularly to support those working more than 48 hours each week and those on call at weekends 1 : 1 or 1 : 2. However, a major expansion of the consultant establishment cannot be achieved rapidly, and will be slowed further if early retirements become more frequent.

RESUMO

AIMS: To measure the total consultant medical microbiologist (CMM) weekly workload, to identify time spent on different activities, and to differentiate those tasks that were viewed by a consensus of consultants as core activities from those that could be accorded a lower priority. METHODS: A self administered questionnaire completed by consultant medical microbiologists in the Public Health Laboratory Service South West Group. RESULTS: Reported hours worked by respondents ranged from 41 to 65 hours each week, excluding on call activities. Eleven of 20 respondents reported working in excess of 48 hours each week. There was no correlation between hours worked and laboratory workload as measured by numbers of specimens. Clinical liaison, result authorisation, infection control, and management activities took up most time. Working practices varied widely between individuals, partly reflecting their differing roles in the laboratory. A consensus was reached regarding the relative importance and priority of many regular CMM activities. CONCLUSIONS: Consultant microbiologists can identify, with consensus, both high and lower priority activities in their daily practice. If such clinical priorities can be more widely agreed across the profession, this would provide a rational approach to workload control.

RESUMO

Meningococcal disease is increasing in incidence in many countries, and effective vaccines for serogroup B strains will not be available for at least 5 to 10 years. In the interim, it is attention to principles of good clinical practice, particularly in the early management of the disease, that have the potential to reduce by half the current case fatality rate of approximately 10%. As discussed in this article, those principles include increased awareness, understanding of the disease and its early symptoms by parents and healthcare professionals, and careful attention to the patient before admission and during the hospital stay.

RESUMO

A postal questionnaire survey was undertaken in registered nursing homes in three different health districts in England: Gloucestershire, North Staffordshire and Leeds. Nursing homes may be registered as general nursing or mental health homes. If homes also have provision for residential beds these are defined as dual registered homes. Overall, 9% (438/4900) of residents, with an equal male:female split, had urinary catheters. There was no significant difference in the overall urinary catheterization rate in the three districts (P=0.9). There was a wide range of urinary catheterization prevalence between homes, with some homes of all three categories having no catheterized residents and several with a prevalence of over 40%. The wide range of prevalence may be due to differences in residents' underlying medical conditions or to differences in attitudes towards urinary catheterization by nursing home staff. Almost all homes (114/124, 92%) stated they had an infection control policy, but 31% (38/124) did not have a written policy on urinary catheter care. In view of the potential for morbidity, infection control policies should include a section on the care of urinary catheters and this should form part of the continuing training of nursing home staff.
