RESUMEN

BACKGROUND: The Improving Access to Psychological Therapies (IAPT) service was established to address common mental health problems among the English population in a timely manner in order to counter the social and economic disadvantage accompanying such difficulties. Using the concept of candidacy, we examined how the legitimacy of claims by people with intellectual disabilities to use this service is facilitated or impeded. METHOD: We used a sequential mixed methods design. We completed 21 interviews with a range of stakeholders, including people with intellectual disabilities and their carers. Themes from the interviews were used to design an online survey questionnaire that was returned by 452 staff from IAPT and specialist intellectual disability services. RESULTS: Using the candidacy framework, we noted that eligibility and access to IAPT were achieved through dynamic and iterative processes of negotiation involving people with intellectual disabilities and their supporters on one side and IAPT staff and service structures on the other. Barriers and facilitators were apparent throughout the seven dimensions of candidacy (identification, navigation, permeability of services, appearances, adjudications, offers and resistance and operating conditions) and were linked to discourses relating to the character and purpose of IAPT and specialist intellectual disability services. CONCLUSIONS: Opportunities exist for some people with intellectual disabilities to assert their candidacy for IAPT input, although there are barriers at individual, professional, organisational and structural levels. More attention needs to be paid to how principles of inclusiveness are operationalised within IAPT teams and to the mental health facilitation role of specialist intellectual disability staff.

RESUMEN

AIMS: To establish the incidence and prevalence of blindness attributable to diabetes in a defined population in Scotland during the period 2000-2009, and to compare these figures with published data from the previous decade in the same population. METHODS: All blind registrations during 2000-2009 in Fife, Scotland, UK were examined and included if diabetic retinopathy/maculopathy was the main cause of blindness. The annual incidence and point prevalence on 31 December 2009 of registered blindness attributable to diabetes were calculated in both the total population and the population with diabetes. These data were compared with figures for the period 1990-1999, using a two-tailed t-test, and subjected to Poisson regression analysis. RESULTS: In the population with diabetes, the mean incidence of blindness attributable to diabetes was 42.7 (sd 24.2, 95% CI 25- 60) per 100 000 per year for 2000-2009, compared with 64.3 for 1990-1999 (P = 0.062). The relative risk of developing blindness per year was 0.894 (95% CI 0.811- 0.988, P = 0.028) for 2000- 2009. The point prevalence on 31 December 2009 was 167 per 100 000 in the population with diabetes, vs 210 on 31 December 1999. CONCLUSION: Compared with the previous decade, the prevalence of blindness attributable to diabetes has decreased in the population with diabetes, with a trend towards a decrease in its incidence. This may be a consequence of an increased denominator population, resulting from better recording of diabetes and changes to the diagnostic criteria. Over the decade 2000-2009, the incidence of blindness attributable to diabetes fell by a mean of 10.6% per year in the population with diabetes.

RESUMEN

Recent changes to out-of-hours primary care in the UK have generated concerns about care for palliative care patients. The aim of this study was to identify key challenges and improvements to out-of-hours palliative care in a mixed urban and rural deprived area. We integrated data from three sources: interviews with patients and professionals, direct observations of services, and routine statistics. Key issues in the provision of care were the importance of good communication and having information available, the unwieldy process of accessing medical care out of hours, professionals bypassing routine out-of-hours care for palliative care patients, and out-of-hours care being provided by practitioners unaware of local services. We recommend provision to out-of-hours services of an enhanced 'special note' for palliative care patients, to be completed early in the course of the illness and updated regularly. The provision for certain complex patients to bypass NHS24 should be considered if routine care is not satisfactory.

RESUMEN

A laser-based ultrasonic technique suitable for characterization of the microstructural state of metal foils is presented. The technique relies on the measurement of the intrinsic attenuation of laser-generated longitudinal waves at frequencies reaching 1 GHz resulting from ultrasonic interaction with the sample microstructure. In order to facilitate accurate measurement of the attenuation, a theoretical model-based signal analysis approach is used. The signal analysis approach isolates aspects of the measured attenuation that depend strictly on the microstructure from geometrical effects. Experimental results obtained in commercially cold worked tungsten foils show excellent agreement with theoretical predictions. Furthermore, the experimental results show that the longitudinal wave attenuation at gigahertz frequencies is strongly influenced by the dislocation content of the foils and may find potential application in the characterization of the microstructure of micron thick metal foils.

RESUMEN

Recently revised UK and US hypertension guidelines have reduced thresholds for both diagnosis and treatment and differ in their recommendations. We have used data from a random, stratified community-based sample of 4784 people aged 65 years and over to compare the prevalence of treatable hypertension and the potential impact on patients and primary care from using current guidelines. BHS, NICE and JNC7 guidelines were applied to blood pressures obtained from primary care medical records (94%) or measured at a screening clinic (6%). Risk factors were obtained by questionnaire and from medical records, supplemented by epidemiological data. Workload was estimated for a representative practice population of 10 000 patients. Blood pressures were obtained on 4514 patients (94%). Prevalence of treatable hypertension was over 67%. Compared to BHS4, prevalence estimates using NICE guidelines were comparable for men but significantly lower for women (P<0.05). They were significantly higher using JNC7 compared with BHS4 and NICE guidance (P<0.05). A general practice of 10 000 patients could expect 1287 older hypertensive patients using BHS4 guidelines and 1231 patients using NICE guidelines. Under BHS4, an extra 94 patients will require annual, rather than 5-yearly review compared with that using the previous guideline. In conclusion, implementation of BHS4 guidelines, with their revised thresholds for diagnosis, will not add materially to the prevalence of treatable hypertension compared to previous BHS3 guidelines but will have a major impact on practice workload. Use of NICE guidelines in preference to BHS4 will result in GPs treating fewer patients and reviewing untreated patients less often.

RESUMEN

INTRODUCTION: The correct interpretation of DXA data is critical to the diagnosis and management of children with suspected bone disease. This study examines the various influences on bone mineral content (BMC), as measured by dual-energy X-ray absorptiometry (DXA). MATERIALS AND METHODS: Six hundred and forty-six healthy school children and forty-three children with chronic diseases, aged 5-18 years, had their lumbar spine and whole body measured using a Lunar DPX-L DXA scanner. RESULTS: Stepwise linear regression identified lean body mass (LBM) as the strongest single predictor of BMC in the lumbar spine and the total body. A significant gender difference was observed in the relationship between BMC and LBM with girls having significantly more bone per unit LBM from 9 years of age in the spine and 13 years of age in the total body. To investigate the relationship between LBM and BMC in children with chronic disease, a two-stage algorithm based upon calculation of Z scores from the normative data was applied. Stage 1 assessed LBM for height and stage 2 assessed BMC for LBM. Ten children with spinal muscular atrophy had a mean LBM for height Z score of -1.8(1.4) but a mean BMC for LBM Z score of 1.2(1.3) indicating their primary abnormality was reduced muscle mass (sarcopenia) with no evidence of osteopenia. In contrast, 21 children with osteogenesis imperfecta had a mean LBM for height Z score of 0.4(1.7) but a mean BMC for LBM Z score of -2.5(1.8) indicating normal LBM for size but significantly reduced BMC for LBM (i.e. osteopenia) confirming a primary bone abnormality. A third group consisting of 12 children with low trauma fractures demonstrated little evidence of sarcopenia [mean LBM for height Z score -1.1(2.1)] but significant osteopenia [mean BMC for LBM Z score -1.9(1.5)]. CONCLUSION: The results from this study demonstrate how the relationship between height and lean body mass, and lean body mass and bone mineral content can be a useful method of diagnosing osteoporosis in children and how the relationships can be used to identify if the primary abnormality is in muscle or bone.

RESUMEN

PURPOSE: To assess the impact of high dose three-dimensional conformal radiotherapy (3D CRT) for prostate cancer on the sexual function-related quality of life of patients and their partners. METHODS AND MATERIALS: Sixty of 124 consecutive patients (median age 72.3 years) treated with 3D CRT for localized prostate cancer were surveyed and reported being potent prior to treatment. The answers to survey questions assessing the impact of quality of life related to sexual function from these 60 patients and their partners forms the basis for this retrospective analysis. RESULTS: Following 3D CRT, 37 of 60 patients (62%) retained sexual function sufficient for intercourse. Intercourse at least once per month was reduced from 71 to 40%, whereas intercourse less than once per year increased from 12 to 35%. Following treatment, 25% of patients reported that the change in sexual dysfunction negatively affected their relationship or resulted in poor self-esteem. This outcome was associated with impotence following treatment (p < 0.01). Patients who had partners and satisfactory sexual function appeared to be at a higher risk of having a negatively affected relationship or losing self-esteem if they become impotent (p < 0.05). Partners of patients who reported a negatively affected relationship or loss of self-esteem appear to be less likely to return the survey instrument used (p = 0.02). CONCLUSIONS: More work is needed to evaluate the impact of radiotherapy and other treatments on the quality of life of patients and their partners to allow adequate informed consent to be given.

RESUMEN

PURPOSE: To assess the impact of high-dose three-dimensional conformal radiotherapy (3DCRT) on potency in patients treated for clinically localized prostate cancer and to identify factors that might predict the outcome of sexual function following treatment. METHODS AND MATERIALS: One hundred twenty-four consecutive patients treated with 3DCRT for localized prostate cancer at UCSF between 1991-1993 were included in this retrospective analysis. Patient responses were obtained from a mailed questionnaire, telephone interviews, or departmental records. Medial follow-up was 21 months. RESULTS: Sixty patients reported having sexual function prior to 3DCRT, including 47 who were fully potent and 13 who were marginally potent. Of the remaining 64 patients, 45 were impotent, 7 were on hormones, 1 was status-postorchiectomy, and 11 were not evaluable. Following 3DCRT, 37 of 60 patients (62%) retained sexual function sufficient for intercourse. Of those with sexual function before irradiation, 33 of 47 (70%) of patients fully potent and 4 of 13 (31%) of patients marginally potent maintained function sufficient for intercourse (p < 0.01). Potency was retained in 6 of 15 (40%) patients with a history of a major urologic surgical procedure (MUSP) and in 31 of 45 (69%) with no history of a MUSP (p < 0.04). Transurethral resection of the prostate was the MUSP in eight of these patients, with four (50%) maintaining sexual function. CONCLUSIONS: Patients who receive definitive 3DCRT for localized prostate cancer appear to maintain potency similar to patients treated with conventional radiotherapy. However, patients who are marginally potent at presentation or who have a history of a MUSP appear to be at increased risk of impotence following 3DCRT.

RESUMEN

PURPOSE: To compare the efficacy of total skin electron beam therapy (TSEBT) with or without adjuvant topical nitrogen mustard (+/- HN2) with topical nitrogen mustard (HN2) alone as initial management of T2 and T3 mycosis fungoides (MF). METHODS AND MATERIALS: A retrospective analysis of 148 patients presenting to Stanford from January, 1970 through January, 1995 within 4 months of pathologic diagnosis of MF. Fifty-five patients with T2 and 27 with T3 disease received TSEBT +/- HN2. Fifty-four patients with T2 and 12 with T3 disease received HN2 alone. Boosts with radiotherapy were usually administered to cutaneous tumors of patients with T3 disease. RESULTS: TSEBT +/- HN2 yielded significantly higher complete response (CR) rates than did HN2 alone in patients with T2 and T3 disease (76% vs 39%, p = 0.03 for T2, and 44% vs 8%, p < 0.05 for T3, respectively). In T2 disease, treatment with adjuvant HN2 was associated with a longer freedom from relapse following TSEBT when compared to observation following a CR to TSEBT (p = 0.068). However, no significant differences in survival were observed for different management programs for T2 or T3 disease. In T2 disease, both TSEBT and HN2 were as effective as salvage therapy as when utilized as initial therapy. However, salvage therapy in T3 disease was rarely effective. Limited tumor involvement in T3 disease did not correlate with improved survival compared to more generalized tumorous disease. MF contributed to 27% and 68% of deaths in patients with T2 and T3 disease, respectively. CONCLUSION: Because of high response rates, management of significantly symptomatic or extensive T2 MF should include TSEBT, and adjuvant HN2 should be administered after a CR to TSEBT. Patients with T2 disease who fail TSEBT or HN2 can be salvaged with the other modality. TSEBT is also an effective treatment for T3 disease. The small subset of patients with limited T3 disease may also be treated with HN2 and local radiotherapy to the tumors. Further investigations are necessary to improve the overall outcome for T3 mycosis fungoides.

RESUMEN

SETTING: Three commercial deer herds, each containing more than 500 deer, experienced outbreaks of tuberculosis (TB) ranging from a 6% prevalence to disease levels >50%. Intensive diagnostic testing was carried out over short time intervals after the initial diagnosis of TB. OBJECTIVE: To eradicate M. bovis infection from herds of farmed red deer (Cervus elaphus) in New Zealand, which had significant outbreaks of tuberculosis (>5%), using complementary diagnostic tests and elective slaughter of all test positive animals. DESIGN: Whole herd mid cervical skin tests (MCT) were used as the primary test and a comparative cervical test (CCT) as an ancillary test. In an attempt to enhance TB eradication, ancillary blood tests comprising; lymphocyte transformation tests (LT) and enzyme-linked immunosorbent assays (ELISA) were used in parallel with MCT, or as serial tests, to complement skin testing. RESULTS: One deer herd (N), which had an acute outbreak (6%) of TB in adult stock, responded quickly to testing and the disease was eradicated within 12 months. A second more chronically infected herd (B), with low prevalence (2%) of TB initially in pregnant hinds which were retained over the breeding cycle, developed widespread uncontrollable spread of infection, that could not be contained by exhaustive testing. The final herd (S), which had an acute outbreak of TB at a prevalence >90% in young fawns, responded well to testing and became TB-free within 1 year. CONCLUSIONS: TB can be eradicated from infected farmed deer herds, using currently available TB tests, irrespective of disease prevalence. The caveat is that disease must be diagnosed early in the acute phase of infection. Undiagnosed infection over winter in breeding hinds in one herd produced a refractory infection in adult males and females and uncontrollable spread to newborn fawns. Disease could not be eradicated using comprehensive diagnostic schedules. A widespread but controllable outbreak of acute TB in another herd, appeared to have caused sufficient selective pressure on adult stock that genetically resistant adults were selected within a very short time frame (<1 year).

RESUMEN

BCG has been used widely as a vaccine to prevent tuberculosis (TB) for 80 years, yet there is still considerable controversy about its efficacy. Many experimental variables have obscured the true efficacy of BCG. The absence of appropriate animal models for the study of protective efficacy and the lack of in vitro correlates of protective immunity have impeded progress. Laboratory animal studies, which have contributed to understanding the pathogenesis, heritability of resistance and immunology of TB, have failed to identify the immunological pathways necessary for protective immunity. In recent years, cattle and deer, which are naturally susceptible to TB, have been used to study protective immunity in vaccinated animals, challenged with virulent bacteria. A deer TB infection model has been developed that can measure protection against TB infection or the development of disease. Data from this model show that, providing live BCG is administered in a short interval prime-boost protocol, significant protection against infection and disease can be obtained. Single dose vaccine provides suboptimal protection that attenuates pathology but does not prevent infection. Low dose BCG vaccine (10(4)cfu), administered in a prime-boost protocol, sufficient to prevent infection, does not cause conversion to delayed type hypersensitivity or produce unacceptable side-effects. Immune memory for protection against infection persists at optimal levels for at least 12 months post vaccination. Used optimally, BCG produces good levels of protection against TB and improved protocols or its use should be explored, before attempts are made to replace it with new-generation vaccines. It is now possible to integrate the fundamental information obtained from laboratory animals with studies of functional immune protection in target host species. Justification for the use of TB vaccines for domestic livestock under field conditions, must be underpinned by scientific evidence that they provide acceptable levels of protection long term.

RESUMEN

BACKGROUND: There is evidence from case-control studies that aminosalicylate drugs can reduce colorectal cancer risk by 75-81% in patients with ulcerative colitis. Patients may fail to comply with long-term therapies, however, or may have been advised to discontinue treatment once in remission. AIM: To describe the usage of long-term aminosalicylate therapy in patients with ulcerative colitis. METHODS: A cross-sectional study was performed using data extracted from general practitioner clinical records on demographic features, extent and duration of disease, use of aminosalicylate therapy and specialist care. RESULTS: Three hundred and sixty-three people had ulcerative colitis and no history of colorectal surgery. Ninety-five of 175 (54%) patients with proctitis, 78 of 123 (63%) patients with left-sided colitis and 28 of 45 (62%) patients with extensive colitis were currently taking an aminosalicylate drug. Those doing so were more likely to be under specialist care than to be definitely or possibly discharged (odds ratio, 4.9; 95% confidence interval, 2.9-8.4). The likelihood of current aminosalicylate therapy was not related to gender or the extent of disease, but was negatively related to the duration of disease. CONCLUSIONS: A substantial minority of patients with ulcerative colitis does not take long-term aminosalicylate therapy. Those who do are more likely to be under specialist care, to be older or to have disease of shorter duration.

RESUMEN

BACKGROUND: The current understanding of quality of life impairment in inflammatory bowel disease has largely been derived from selected populations and may not reflect the experience of patients in the community, where fewer than half are likely to be under specialist care. AIM: To describe the health-related quality of life in a community-based sample of patients with established inflammatory bowel disease and explore its association with the type and extent of disease, gender, age, material deprivation and other factors. METHODS: Adults with established inflammatory bowel disease were identified systematically from the records of 23 family practices in north-east England. The health-related quality of life was assessed by self-completion of the UK Inflammatory Bowel Disease Questionnaire. RESULTS: Five hundred and fifty-six patients were sent the questionnaire and 409 (74%) gave usable replies. Lower scores (worse quality of life) were significantly associated with female gender, Crohn's disease, more extensive disease (ulcerative colitis) and being under specialist care. The mean health-related quality of life score was significantly lower in patients resident in more deprived districts, independent of the type and extent of disease. CONCLUSIONS: Most patients with established inflammatory bowel disease showed only minor impairment of their health-related quality of life. On average, women and those with Crohn's disease were relatively more affected. Clinicians responsible for the care of patients with inflammatory bowel disease should be aware of these more vulnerable groups.

RESUMEN

AIMS: To identify a model to assess general practitioner use of pathology services that could be applied to assess specific interventions designed to promote best practice. METHODS: A database containing standardised requesting data for 22 general practices was constructed. The database contained 28 tests covering 95% of general practitioner activity, distributed across pathology, and it was evaluated during two sequential six month periods. A comparison of ranks of requesting activity between different time periods was undertaken by calculating Pearson rank correlation coefficients. Requesting numbers were also adjusted for patients' age and sex distributions within the 22 practices for a sample of three high volume tests. The effects of distributing requesting guidelines and details of requesting activity were assessed during two sequential three month periods. RESULTS: Requesting activity was extremely stable during the two baseline periods for most test (r > 0.80 for 20 of the 28 tests). Several less discriminatory tests were identified. Age and sex adjustment had minimal impact on the ranks of requesting activity. Requesting activity during the two three month periods after distributing guidelines and comparative details of individual requesting activity showed little change (overall correlation coefficient, 0.844 between baseline and intervention periods). CONCLUSIONS: Ranking general practitioners requesting activity adjusted for practice list size provides a reproducible means of measuring requesting activity for most pathology tests performed in general practice. Activity was not influenced by age or sex of patients on the practice list. Distributing requesting guidelines and individual requesting activity on their own do not have any measurable impact on requesting activity. More innovative (possibly multiple) interventions might be required to influence general practitioner requesting practice.

RESUMEN

AIMS: To examine whether variations in pathology test requesting between different general practices can be accounted for by sociodemographic or other descriptive indicators of the practice. METHOD: This was a comparative analysis of requesting patterns across a range of pathology tests representing 95% of those requested in general practice, in 22 general practices in a single district, serving a population of 165 000. Spearman correlation coefficients were calculated and both the top and bottom fifths of activity were displayed graphically to detect trends at the extremes of the ranges. RESULTS: The proportion of women of childbearing age, median practice Townsend scores, or the existence of specialist miniclinics within the practice did not have a demonstrable impact on requesting patterns. A weak correlation was found between the proportion of elderly patients and creatinine/electrolyte testing but not for the other two tests examined for this patient group. CONCLUSIONS: The large differences observed in general practice pathology requesting probably result mostly from individual variation in clinical practice and are therefore potentially amenable to change.

RESUMEN

An association between diminished respiratory function and an environmental agent should reflect the magnitude of the exposure and not be due to technical error, bias, confounding factors, or chance. Bias is difficult to avoid; the best course is to make comparisons within a population of exposed individuals, not between them and a control group; the population should be defined and a high response rate achieved. The principal confounding factors are age, smoking, and other environmental exposures; their effects should be fully estimated for the population in question as otherwise they will be wrongly attributed to the environmental agent. Finally, the results should be scrutinized and, if possible, a second independent study should be planned.

RESUMEN

BACKGROUND: Cryosurgical ablation of malignant hepatic tumors is being increasingly used for definitive treatment of metastatic colorectal and primary hepatic tumors. The lack of tumor necrosis near vessels that results from inadequate freezing may contribute to local recurrence and thus limit the applications of this therapy. This study was designed to determine whether single-freeze cryoablation could cause necrosis of both the pervascular and intralesional hepatic parenchyma. METHODS: Ten pigs were treated with one 15-minute cycle of cryoablation. Five additional animals were treated with overlapping cryolesions to simulate a double freeze. After 24 hours, animals underwent reoperation with portal vein cannulation and infusion of formalin. Serial sectioning and hematoxylin and eosin staining of cryolesions were performed. RESULTS: Complete cell death was visualized within all cryolesions. There was no difference between once or twice-frozen tissue. Vessels within or adjacent to cryolesions showed necrosis of hepatic tissue up to the vessel wall. No sections revealed incomplete necrosis of perivascular hepatic parenchyma. CONCLUSIONS: Single-freeze cryoablation results in necrosis of intralesional hepatic parenchyma without added benefit from repeat freezing. Complete necrosis of the perivascular tissue suggests that cryosurgical ablation can effectively cause necrosis immediately adjacent to vessels without concerns of incomplete ablation resulting from the heat sink effect.

RESUMEN

OBJECTIVE: To describe a classification of errors and to assess the feasibility and acceptability of a method for recording staff reported errors in general practice. DESIGN: An iterative process in a pilot practice was used to develop a classification of errors. This was incorporated in an anonymous self-report form which was then used to collect information on errors during June 2002. The acceptability of the reporting process was assessed using a self-completion questionnaire. SETTING: UK general practice. PARTICIPANTS: Ten general practices in the North East of England. MAIN OUTCOME MEASURES: Classification of errors, frequency of errors, error rates per 1000 appointments, acceptability of the process to participants. RESULTS: 101 events were used to create an initial error classification. This contained six categories: prescriptions, communication, appointments, equipment, clinical care, and "other" errors. Subsequently, 940 errors were recorded in a single 2 week period from 10 practices, providing additional information. 42% (397/940) were related to prescriptions, although only 6% (22/397) of these were medication errors. Communication errors accounted for 30% (282/940) of errors and clinical errors 3% (24/940). The overall error rate was 75.6/1000 appointments (95% CI 71 to 80). The method of error reporting was found to be acceptable by 68% (36/53) of respondents with only 8% (4/53) finding the process threatening. CONCLUSION: We have developed a classification of errors and described a practical and acceptable method for reporting them that can be used as part of the process of risk management. Errors are common and, although all have the potential to lead to an adverse event, most are administrative.

RESUMEN

OBJECTIVE: Microsurgery and stereotactic radiosurgery (SRS) for vestibular schwannomas are associated with a relatively high incidence of sensorineural hearing loss. A prospective trial of fractionated SRS was undertaken in an attempt to preserve hearing and minimize incidental cranial nerve injury. METHODS: Thirty-three patients with vestibular schwannomas were treated with 2100 cGy in three fractions during a 24-hour period using conventional frame-based linear accelerator radiosurgery. The median tumor diameter was 20 mm (range, 7-42 mm). Baseline and follow-up evaluations included audiometry and contrast-enhanced magnetic resonance imaging. End points were tumor progression, preservation of serviceable hearing, and treatment-related complications. RESULTS: Thirty-one patients (32 tumors) were assessable for tumor progression and treatment-related complications and 21 patients for preservation of serviceable hearing, with a median follow-up interval of 2 years (range, 0.5-4.0 yr). Tumor regression or stabilization was documented in 30 patients (97%) and tumor progression in 1 (3%). The patient with tumor progression remains asymptomatic and has not required surgical intervention. Five patients (16%) developed trigeminal nerve injury at a median of 6 months (range, 4-12 mo) after SRS; two of these patients had preexisting trigeminal neuropathy. One patient (3%) developed facial nerve injury (House-Brackmann Class 3) 7 months after SRS. Preservation of useful hearing (Gardner-Robertson Class 1-2) was 77% at 2 years. All patients with pretreatment Gardner-Robertson Class 1 to 2 hearing maintained serviceable (Class 1-3) hearing as of their last follow-up examination. CONCLUSION: Three-fraction SRS with a conventional stereotactic frame is feasible and well tolerated in the treatment of acoustic neuroma. This study demonstrates a high rate of hearing preservation and few treatment-related complications among a relatively high-risk patient cohort (tumors >15 mm or neurofibromatosis Type 2). Longer follow-up will be required to assess the durability of tumor control.
