The impact and indications for Oncotype DX on adjuvant treatment recommendations when third-party funding is unavailable.

OBJECTIVES: Industry-supported decision impact studies demonstrate that Oncotype Dx (ODX) changes treatment recommendations (TR) in 24-40% of hormone receptor+/HER2- patients. ODX is not reimbursed by third-party payers in Australia, potentially resulting in more selective use. We sought to evaluate the impact of self-funded ODX on TRs. METHODS: Data collected included demographics, tumor characteristics, indication for ODX and pre- and post-recurrence score (RS) TR. Primary endpoint was frequency of TR change and associations with TR change were sought. RESULTS: Eighteen physicians contributed 382 patients (median age 54). A total of 232 (61%) of tumors were T1 and were grade 1, 2 and 3 in 49 (13%), 252 (66%) and 79 (21%). A total of 257 (67%) were node negative. Assay indications were: confirm need for chemotherapy (CT) (36%), confirm omission of CT (40%) and genuine equipoise (24%). RS was low (≤17) in 55%, intermediate (18-31) in 36% and high (≥32) in 9%. Thirty-eight percent of patients had TR change post-ODX. Sixty-five percent of patients recommended CT pre-ODX changed to hormone therapy alone (HT)-more likely if lower grade and if ER and/or PR > 10%. Fourteen percent of patients with pre-ODX TR for HT added CT-more likely if ER and/or PR ≤10% and if Ki67 > 15% Overall, TR for CT decreased from 47% to 24%. CONCLUSION: Patient-funded ODX changed TRs in 38% of patients, de-escalating 65% from CT to HT and adding CT to 14% of those recommended HT. These changes were greater than an industry-funded study suggesting that physicians can identify situations where the assay may influence decisions.

MRI Features Can Predict 1p/19q Status in Intracranial Gliomas.

BACKGROUND AND PURPOSE: The 2016 revision of the World Health Organization Classification of Tumors of the Central Nervous System mandates codeletion of chromosomes 1p and 19q for the diagnosis of oligodendroglioma. We studied whether conventional MR imaging features could predict 1p/19q status. MATERIALS AND METHODS: Patients with previous 1p/19q testing were identified through pathology department records, typically performed on the basis of an oligodendroglial component on routine histology; 69 patients met the inclusion criteria. Preoperative imaging of patients with grade II or III gliomas was retrospectively assessed by 2 neuroradiologists, blinded to the 1p/19q status. Thirteen MR imaging features were first assessed in a small initial cohort (n = 10), after which the criteria were narrowed for the remaining patients as a validation cohort. RESULTS: There was 85% agreement between radiologists for the overall prediction of 1p/19q status in the validation cohort, with an accuracy of 84%. The presence of >50% T2-FLAIR mismatch and calcification was found to be the most useful for predicting 1p/19q status. The >50% T2-FLAIR mismatch variable was demonstrated in 14 tumors and had 100% specificity for identifying a noncodeleted tumor (P = .001), with 97% interobserver correlation. Calcification was visualized in 7 tumors, 6 of which were 1p/19q codeleted (specificity, 97%; P = .006), with 100% interobserver correlation. CONCLUSIONS: The presence of >50% T2-FLAIR mismatch is highly predictive of a noncodeleted tumor, while calcifications suggest a 1p/19q codeleted tumor. If formal 1p/19q testing is not possible, a combined MR imaging-histologic assessment may improve the diagnostic accuracy over histology alone.

Bone loss with antiepileptic drug therapy: a twin and sibling study.

Changes in areal bone mineral density (aBMD) and other predictors of bone loss were evaluated in 48 same-sex twin/age-matched sibling pairs discordant for antiepileptic drug (AED) use. AED users had reduced BMD at the hip regions. Prolonged AED users had greater aBMD loss, predicting a higher risk of bone fragility. INTRODUCTION: To investigate the longitudinal associations of bone mineral measures with antiepileptic drug (AED) use, including enzyme-inducing (EIAED) and non-enzyme-inducing (NEIAED) types, and other predictors of bone loss in a study of 48 same-sex twin/age-matched sibling pairs (40 female, 8 male) discordant for AED use. METHODS: Using dual-energy X-ray absorptiometry (DXA), areal bone mineral density (aBMD) and content (BMC) at the hip regions, forearm, lumbar spine, and whole body were measured twice, at least 2 years apart. The mean within-pair difference (MWPD), MWPD%, and mean annual rate of aBMD change were adjusted for age, weight, and height. Predictors of bone loss were evaluated. RESULTS: AED users, compared to non-users, at baseline and follow-up, respectively, had reduced aBMD at the total hip (MWPD% 3.8, 4.4%), femoral neck (4.7, 4.5%), and trochanter regions (4.1, 4.6%) (p < 0.05). For the whole cohort, the annual rate of change in all aBMD/BMC (p > 0.05) regions did not differ within pairs. Nevertheless, EIAED users had greater aBMD loss than non-users (n = 20 pairs) at the total hip (1.7 vs. 0.3%, p = 0.013) and whole body regions (0.7% loss vs. 0.1% BMD gain, p = 0.019), which was not found in NEIAED-discordant pairs (n = 16). AED use >20 years predicted higher aBMD loss at the forearm (p = 0.028), whole body (p = 0.010), and whole body BMC (p = 0.031). CONCLUSIONS: AED users had reduced aBMD at the hip regions. Prolonged users and EIAED users had greater aBMD loss, predicting a higher risk of bone fragility. Further prospective studies of AED effects on bone microarchitecture are needed.

Determinants of bone mineral density in young Australian women; results from the Safe-D study.

The study aimed to explore determinants of bone parameters in young women. Most bone parameters were associated with height and lean mass. Bone parameters were not associated with vitamin D status. Future research should address whether interventions aimed at improving lean mass are beneficial to bone health in young women. INTRODUCTION: The implementation of prevention strategies during young adulthood may be crucial for osteoporosis prevention in later life, yet literature examining the determinants of bone health in premenopausal women is limited. We aimed to assess determinants of bone health, including serum 25-hydroxyvitamin D (25OHD), in females aged 16-25 years, living in Victoria, Australia, recruited through Facebook advertising. METHODS: Serum 25OHD was measured by liquid chromatography-tandem mass spectrometry and bone health was measured using dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) in 326 participants. RESULTS: Mean (± standard deviation) serum 25OHD was 69 ± 28 nmol/L and the prevalence of vitamin D deficiency (serum 25OHD <50 nmol/L) was 26%. Seven percent of participants (n = 23) reported taking a vitamin D supplement. Two percent of participants had low lumbar spine bone mineral density (Z-score <-2.0), 5% at the hip and 7% at the femoral neck. Serum 25OHD levels were not associated with DXA bone parameters, nor with pQCT bone parameters. Most bone parameters were positively associated with height and lean mass. CONCLUSION: Vitamin D status was not associated with bone health in young women in the current study. Our findings suggest that targeting other modifiable factors, such as lean body mass, is likely to be beneficial to bone health in young women. Longitudinal studies examining the association between vitamin D status and bone health in young women are necessary to confirm our findings. In addition, whether raising 25OHD levels is advantageous for young women's bone health is yet to be determined.

The association between inflammation, obesity and elevated blood pressure in 16-25-year-old females.

There is evidence to show an association between inflammation, obesity and elevated blood pressure. However, there is limited data for this relationship in adolescent females. We aimed to investigate the association between high sensitivity C-reactive protein (hs-CRP) and elevated blood pressure in young Australian females. Women aged 16-25 years living in Victoria were randomly recruited via targeted Facebook advertising. Socio-demographic information was collected via a web-based questionnaire. Anthropometric and blood pressure measurements were conducted by trained staff. Hs-CRP was assessed using the Abbott Architect assay. The demographic data were collected from 639 females (mean ±s.d. age: 22±3). The blood pressure data were available for 502 participants. Approximately 28% had elevated blood pressure (defined by a blood pressure reading ⩾120-139/80-89 mm Hg for adults and >90th and <95th percentiles for age, sex and height for adolescents). Approximately 24% had hs-CRP >3.0 mg l-1 and 30% were overweight or obese. In multivariable logistic regression analyses, obese females (OR: 5.5, 95% CI: 2.4-12.5, P<0.001) were more likely to have elevated blood pressure compared with those with a body mass index (BMI) in the normal range. Elevated hs-CRP levels were associated with an increased odds of elevated blood pressure (OR: 3.4, 95% CI: 1.8-6.3, P<0.001). However, this association was no longer significant after adjustment for BMI. Findings from this study demonstrate that hs-CRP and obesity are associated with elevated blood pressure in young females. Thus, our findings may promote further research into the underlying mechanisms of these associations and related long-term health risks.

Impact of insulin initiation on glycaemic variability and glucose profiles in a primary healthcare Type 2 diabetes cohort: analysis of continuous glucose monitoring data from the INITIATION study.

AIM: To use continuous glucose monitoring to examine the effects of insulin initiation with glargine, with or without glulisine, on glycaemic variability and glycaemia in a cohort of people with Type 2 diabetes receiving maximum oral hypoglycaemic agents in primary healthcare. METHODS: We conducted a post hoc analysis of continuous glucose monitoring data from 89 participants at baseline and at 24 weeks after insulin commencement. Indicators of glycaemic variability (standard deviation, J-index and mean amplitude of glycaemic excursion) and glycaemia (HbA1c , mean glucose, area under the glucose-time curve) were assessed. Multi-level regression analysis was used to identify the predictors of change. RESULTS: Complete glycaemic variability data were available for 78 participants. Of these participants, 41% were women, their mean (sd) age was 59.2 (10.4) years, the median (interquartile range) diabetes duration was 10.4 (6.5, 13.3) years and the median (interquartile range) baseline HbA1c was 82.5 (71.6, 96.7) mmol/mol [9.7 (8.7, 11.0)%]. At baseline, BMI correlated negatively with standard deviation (r = -0.30) and mean amplitude of glycaemic excursion (r = -0.26), but not with J-index; HbA1c correlated with J-index (r = 0.61) but not with mean amplitude of glycaemic excursion and standard deviation. After insulin initiation the mean (sd) glucose level decreased [from 12.0 (3.0) to 8.5 (1.6) mmol/l; P < 0.001], as did the median (interquartile range) J-index [from 66.9 (47.7, 95.1) to 36.9 (27.6, 49.8) mmol/l; P < 0.001]. Baseline HbA1c correlated with a greater J-index reduction (r = -0.45; P < 0.001). The mean amplitude of glycaemic excursion and standard deviation values were unchanged. The baseline temporal profile, showing elevated postprandial morning glucose levels, was unchanged after insulin initiation, despite an overall reduction in glycaemia. CONCLUSION: Insulin initiation reduced hyperglycaemia but did not alter glycaemic variability in adults with Type 2 diabetes receiving maximum oral hypoglycaemic agents. The most significant postprandial excursions were seen in the morning, which identifies prebreakfast as the most effective target for short-acting insulin therapy.

Outcomes in emergency general surgery following the introduction of a consultant-led unit.

BACKGROUND: Patients presenting with emergency surgical conditions place significant demands on healthcare services globally. The need to improve emergency surgical care has led to establishment of consultant-led emergency surgery units. The aim of this study was to determine the effect of a changed model of service on outcomes. METHODS: A retrospective observational study of all consecutive emergency general surgical admissions in 2009-2012 was performed. A 2-year time frame before and after the establishment of the emergency general surgery (EGS) service was used to determine the number of admissions and operations, emergency department and hospital length of stay, as well as complication rates. RESULTS: The study included 7233 acute admissions. The EGS service managed 4468 patients (61·6 per cent increase) and performed 1804 operations (41·0 per cent increase). The most common diagnoses during the EGS period included acute appendicitis (532, 11·9 per cent), biliary disease (361, 8·1 per cent) and abdominal pain (561, 12·6 per cent). Appendicectomy (536, 29·7 per cent), cholecystectomy (239, 13·2 per cent) and laparotomy (226, 12·5 per cent) were the most commonly performed procedures. In the EGS period, time in the emergency department was reduced (from 8·0 to 6·0 h; P < 0·001), as was length of hospital stay (from 3·0 to 2·0 days; P < 0·001). The number of complications was reduced by 46·8 per cent, from 172 (6·2 per cent) to 147 (3·3 per cent) (P < 0·001), with a 53 per cent reduction in the number of deaths in the EGS period, from 29 (16·9 per cent) to seven (8 per cent) (P = 0·039). CONCLUSION: The establishment of a consultant-led emergency surgical service has been associated with improved provision of care, resulting in timely management and improved clinical outcomes.

Efficacy of thiopurines and adalimumab in preventing Crohn's disease recurrence in high-risk patients - a POCER study analysis.

BACKGROUND: Crohn's disease recurs in the majority of patients after intestinal resection. AIM: To compare the relative efficacy of thiopurines and anti-TNF therapy in patients at high risk of disease recurrence. METHODS: As part of a larger study comparing post-operative management strategies, patients at high risk of recurrence (smoker, perforating disease, ≥2nd operation) were treated after resection of all macroscopic disease with 3 months metronidazole together with either azathioprine 2 mg/kg/day or mercaptopurine 1.5 mg/kg/day. Thiopurine-intolerant patients received adalimumab induction then 40 mg fortnightly. Patients underwent colonoscopy at 6 months with endoscopic recurrence assessed blind to treatment. RESULTS: A total of 101 patients [50% male; median (IQR) age 36 (25-46) years] were included. There were no differences in disease history between thiopurine- and adalimumab-treated patients. Fifteen patients withdrew prior to 6 months, five due to symptom recurrence (of whom four were colonoscoped). Endoscopic recurrence (Rutgeerts score i2-i4) occurred in 33 of 73 (45%) thiopurine vs. 6 of 28 (21%) adalimumab-treated patients [intention-to-treat (ITT); P = 0.028] or 24 of 62 (39%) vs. 3 of 24 (13%) respectively [per-protocol analysis (PPA); P = 0.020]. Complete mucosal endoscopic normality (Rutgeerts i0) occurred in 17/73 (23%) vs. 15/28 (54%) (ITT; P = 0.003) and in 27% vs. 63% (PPA; P = 0.002). The most advanced disease (Rutgeerts i3 and i4) occurred in 8% vs. 4% (thiopurine vs. adalimumab). CONCLUSIONS: In Crohn's disease patients at high risk of post-operative recurrence adalimumab is superior to thiopurines in preventing early disease recurrence.

Geographical variation in incidence of knee arthroscopy for patients with osteoarthritis: a population-based analysis of Victorian hospital separations data.

BACKGROUND/AIM: To evaluate the frequency and geographical variation in knee arthroscopy for adults (>25 years) with a concomitant diagnosis of osteoarthritis. METHODS: This was a retrospective cohort study of hospital separations involving an elective knee arthroscopy in public and private hospitals in Victoria, Australia. Participants included patients receiving knee arthroscopies with a diagnosis code indicating osteoarthritis (OA) from 1 July 2008 to 30 June 2009. Records were excluded if the patient was under 25 years or their arthroscopy involved a ligament reconstruction. Crude rates per 100 000 population and negative binomial regression offset by total knee arthroscopy volume were used to analyse differences by region. RESULTS: There were 9620 arthroscopic procedures meeting the inclusion criteria. There were 5500 (57.2%) admissions where the principal diagnosis was knee OA (gonarthrosis) and 3510 (36.5%) where the principal diagnosis indicated a mechanical derangement and there was a primary or associated diagnosis of OA. When we examined the incidence rate ratios (IRR) by region, after adjustment for relevant factors and accounting for the total knee arthroscopy volume within each region, we identified significant variation in knee arthroscopy rates for patients with OA. The region with the highest adjusted IRR was Barwon South Western (IRR: 1.26, 95% confidence interval (CI): 1.16-1.36) and the region with lowest adjusted incidence rate ratio was the Gippsland region (IRR: 0.89, 95% CI: 0.80-0.98). CONCLUSIONS: We identified considerable geographical variation in arthroscopies for people with OA across Victoria. Further investigation is needed to understand whether this variation is a reflection of differences in OA prevalence, clinical decision-making or access.

[Monitoring and antibiotic resistance profile of tracheal aspirate microbiota in ICU children with severe craniocerebral trauma].

Nosocomial infections and their rational antibiotic treatment represent a major challenge for the healthcare nowadays. In this context, gramnegative bacteria including Pseudomonas aeruginosa, Acinetobacter baumanii and Enterobacteriaceae spp. are etiologically important and characterized by a significant level of antibiotic resistance. To examine dynamics of the respiratory tract colonization by hospital flora, tracheal aspirates obtained at three time points from 69 children with severe craniocerebral trauma during their stay in ICU were analysed. Colonization was observed on the 4th day of the ICU stay with predomination of K. pneumoniae (45%) and A. baumanii (27-37%). P. aeruginosa was detected after the 8th day of the ICU stay with the isolation rate of 33%. Substantial proportions of P. aeruginosa (61%), A. baumanii (78%) and K. pneumoniae (25%) were resistant to carbapenems. In 65 carbapemen resistant isolates, the presence of carbapenemases was examined using PCRs. OXA-48 carbapenemase was detected in 11 out of 14 (78%) K. pneumoniae isolates. Among the A. baumanii isolates, 30/31 (97%) carried OXA-40 and 1/31 (3%) had OXA-23 carbapenemases. None of the examined A. baumanii and K. pneumoniae isolates produced metallo-betalactamases (MBL). In contrast, all 20 carbapenem resistant P. aeruginosa isolates produced a MBL, and in 12 out of 20 (60%) of theme VIM-2 was detected. Thus, gramnegative nosocomial microflora rapidly colonizes ICU patients and has a high level of resistance to antibiotics, including carbapenems.

[On possibility of partial restore integrative brain activity in patients with vegetative state].

A combined approach to neuroreconstructive effects on pathogenesis mechanisms of vegetative state that develops as a result of severe traumatic brain injury (TBI). It is shown that under the influence of chemical transtimpanal vestibular dereception and transcranial micropolarization (TDCS) accelerated and more pronounced therapeutic effect than conventional therapy. Neurophysiological in-depth examination of the dynamics shows that over time in patients in a vegetative state, picking up the intensity, "tension" and "rigidity" of inter-regional cortical interactions in the organization that are beginning to dominate the area TPO cortex of both hemispheres. It is suggested that in the dislocation of the brain stem in severe TBI is vestibulotalamic tract, thanks to its anatomical location, is the least vulnerable. As a result, the prevailing afferentation forming inter-regional cortical interactions is vestibular afferent impulses. On its basis the pathological functional system, blocking the work of other functional systems of the damaged brain. Suggested treatments significantly reduce the amount of vestibular afferent flow and open up the possibility of recovery of more effective interafferential interactions. This greatly facilitates the work of the brain as a multimodal analyzer.

Epidemiology of hepatitis B-associated hepatocellular carcinoma in Victoria.

BACKGROUND: Chronic hepatitis B (HBV) and cirrhosis are major risk factors for hepatocellular carcinoma (HCC). The proportion and characteristics of cases with cirrhosis are not well documented. AIM: Our aim was to compare demographic, viral and tumour characteristics of HBV-associated HCC in an Australian cohort, in patients with and without cirrhosis. METHODS: Existing HCC databases at six Melbourne teaching hospitals were reviewed for cases associated with HBV. Patient demographics, HBV viral characteristics, presence of cirrhosis, serum alpha-fetoprotein and tumour size were assessed. Mode of diagnosis was recorded through surveillance or symptoms, and treatment was either palliative, percutaneous or surgical. RESULTS: We identified 197 cases of HBV-related HCC. The mean age was 57.9 ± 12.9 years; 83% were male, and 55.3% and 35.3% were of Asian and European descent respectively. Of 168 patient with available data, 146 (87%) had cirrhosis versus 22 (13%) without. Patients with cirrhosis tended to be older (median 60 vs 52 years, P = 0.078). Asian patients were more likely to have HCC without cirrhosis than Europeans (17% vs 6%, P = 0.04). There were no other differences identified between cirrhotic and non-cirrhotic patients. Thirty-four per cent of patients had tumours greater than 5 cm at diagnosis, and 47% were diagnosed after presenting with symptoms. Twelve patients with HBV-HCC were outside current screening guidelines. CONCLUSION: Most patients in Melbourne with HBV-associated HCC have cirrhosis. HCC characteristics in non-cirrhotic and cirrhotic patients were similar. The large number of patients detected through symptoms and with large tumours reinforces the need for vigilance in screening.

Primary angiitis of the central nervous system: experience of a Victorian tertiary-referral hospital.

BACKGROUND: Primary angiitis of the central nervous system is a rare condition, which is often difficult to diagnose and is associated with significant morbidity and mortality. There is no standardised treatment protocol or randomised clinical trial evidence to guide management. AIM: To describe the clinical features, diagnostic modalities, treatment and outcomes in an Australian hospital population-based series of primary cerebral angiitis. METHODS: Data were collected via retrospective medical record review of patients with primary angiitis of the central nervous system for the period 1 July 1998 to 30 June 2009, using previously published diagnostic criteria. Eligible patient records were identified in two ways; from routinely collected hospital episode data, coded using the ICD-10-AM coding standard and by review of cerebral biopsy data. RESULTS: Ten of 12 included patients had a positive cerebral biopsy, with two patients diagnosed by angiography. Mean age at diagnosis was 47.2 years (range 18-73 years), with a female predominance of 5:1. Headache was the most common symptom experienced. Seventy per cent of the biopsy specimens showed a lymphocytic vasculitis. All patients received treatment with either steroids alone or a combination of steroids and cyclophosphamide, the latter treatment being initiated for those with a higher modified Rankin score of disability. Nine (75%) responded to treatment. There was one in-hospital death, and two patients had no documented response to treatment. CONCLUSION: This study presents the first Australian case series data of primary cerebral angiitis. Better understanding of management and outcomes of this rare condition would be gained through multicentre studies.

[The role of vestibular afferentation in the system cooperation's of cortical field's human brain].

For the purpose of studying of a role vestibular afftrentation in the organization of system interaction of cortical fields of a brain of the person dynamics of inter-regional cortical interactions at patients by a cervical dystonia in the course of their treatment by a method transtimpanal chemical vestibular dereception was investigated. It is shown, what even at unilateral vestibular dereception deep reorganization of system interaction distance the separated cortical areas, mentioning, first of all, back and forward associative zones of both hemispheres is observed. The laws specifying for an organizing role vestibular afftrentation in the organization of integrative activity of a brain that confirms its system value are revealed.

Prognostic factors in the elderly: a profile and outcomes study of a community palliative care service.

Our ageing population creates challenges for palliative care, including accuracy of prognostication. This study highlights this by profiling the outcomes of an Australian, community-based palliative service over 6 months with collection of epidemiological, comorbidity and physical function data. Most patients had cancer, comorbidities and died during the study. Low scores on the Australian-modified Karnofsky Performance Scale and the presence of congestive cardiac failure were predictive of shorter survival.

Type 2 diabetes does not worsen prognosis in hepatocellular carcinoma.

INTRODUCTION: Type 2 diabetes (T2DM) is associated with liver inflammation and carcinogenesis. The prevalence of T2DM among patients with liver cirrhosis and hepatocellular carcinoma is increasing. However, the effect of T2DM on the natural history of hepatocellular carcinoma is not known. AIM: To examine the effect of T2DM on hepatocellular carcinoma (HCC) survival in treated and untreated disease. METHODS: Retrospective analysis was performed on HCC cases diagnosed during 2000-2005, and prospectively during 2006-August 2007. Demographics, HCC staging, response to treatment, and survival were collected. A comparison was made between patients with T2DM and without T2DM. RESULTS: One hundred and thirty-five patients were recruited in total; 58 (43%) had T2DM. Seventy (37 diabetic) patients were treated with percutaneous radiological therapies, with 168 treatments given. Treatment was determined by AASLD guidelines and patient tolerance, there was no randomisation. There was no significant difference in survival between diabetic and nondiabetic patients. There was a nonsignificant trend towards greater survival in diabetic patients (overall median survival diabetics 21 mths vs nondiabetics 5 mths, P=0.355). CONCLUSIONS: T2DM does not negatively impact on the natural history of treated or untreated HCC.

Redesigning care for chronic conditions: improving hospital-based ambulatory care for people with osteoarthritis of the hip and knee.

BACKGROUND: Osteoarthritis of the hip and knee is a highly prevalent chronic condition in Australia that commonly affects older people who have other comorbidities. We report the pilot implementation of a new chronic disease management osteoarthritis service, which was multidisciplinary, evidence-based, supported patient self-management and care coordination. METHODS: A musculoskeletal coordinator role was pivotal to service redesign and osteoarthritis pathway implementation. Impact evaluation included: service utilization, patient and general practitioner service experience, a 'before and after' audit of clinician adherence to recommendations, and 3- and 6-month patient health outcomes (pain, physical function, patient and physician global health (Visual Analogue Scale), disability (Multi-Attribute Prioritisation Tool), Partners in Health Scale and body mass index). RESULTS: A total of 123 patients, median age of 66 years, were assessed. Documentation of osteoarthritis assessment and management improved for all parameters. At 3 months there were improvements in self-reported pain (P < 0.001), global function (P < 0.001), physician and patient reported global health (P < 0.001), Partners in Health Score (P < 0.001) and Hip and Knee Multi-Attribute Prioritisation Tool score (P < 0.014). Body mass index did not improve. Patients and general practitioners reported positive experiences, but there was variable uptake of recommendations by patients. The main factors influencing uptake of recommendations were access block to community services in the first 3 months and patient preferences for therapy. The cost implications for implementation were low. CONCLUSION: The osteoarthritis service model is feasible to implement, is well received by patients and staff, and provides a template for translation into other settings.

[Clinical and neurophysiological manifestations of cerebral asymmetry in cervical dystonia].

Based on the analysis of clinical and neurophysiological data with the use of up-to-date methods of EEG processing, the authors discuss a role of cerebral asymmetry (CA) in the pathogenesis of cervical dystonia (CD). Sixty-seven patients (31 male and 36 female) with CD have been studied. The pathological turn of the head to the right side (RT) was observed in 34 patients, to the left side (LT) - in 33 patients. The uni- or bilateral generalization of dystonic symptoms (Meig's syndrome, laterocollis) was found only in one-third of RT patients. The visual analysis of EEG of RT patients revealed the high level of EEG synchronization with signs of cortical irritation, with the prevalence in the left hemisphere, and the presence of focal epileptiform appearances in the temporal leads of the left or both hemispheres with the left-side prevalence. In LT patients, the EEG presentation was similar to normal but more often represented the variants of <> EEG-pattern. In these cases, the apparent manifestations of CA were not found. The coherent analysis revealed the formation of the network of <> coherent links, with bilateral spread, in RT patients. This may suggest the functional inequivalence of the peripersonal space of right and left hand and the dominate significance of striopallidar and thalamic structures of the left hemisphere for the total brain activity.
