Abstract
Background: Integrating palliative care in the management of patients with lung cancer improves quality of life, patient satisfaction, and overall survival. However, few patients receive timely palliative care consultation. The Lung Diagnostic Assessment Program (LDAP) in Southeastern Ontario is a multidisciplinary rapid assessment clinic that expedites the diagnosis and management of patients with suspected lung cancer. Objectives: We sought to increase the percentage of LDAP patients with stage IV lung cancer receiving palliative care consultation within three months of diagnosis. Design: We integrated a palliative care specialist in LDAP to facilitate in-person, same-visit consultation for patients with a new lung cancer diagnosis. Setting/Subjects: Five hundred fifty patients in a Canadian academic center (154 initial baseline, 104 COVID baseline, 292 post-palliative care integration). Measurements: Baseline data were established using retrospective chart review (February-June 2020 and December 2020-March 2021 due to COVID-19 pandemic). Data were collected prospectively to assess improvement (March-August 2021). Statistical Process Control charts assessed for special cause variation; chi-square tests assessed for differences between groups. Results: The percentage of patients with stage IV lung cancer seen by palliative care within three months increased from 21.8% (12/55) during early-COVID baseline to 49.2% (32/65) after palliative care integration (p < 0.006). Palliative care integration in LDAP reduced mean time from referral to consultation from 24.8 to 12.3 days, including same-day consultation for 15/32 (46.8%) patients with stage IV disease. Conclusions: Integrating palliative care specialists into LDAP improved the timeliness of palliative care assessment for patients with stage IV lung cancer.

Prospective Evaluation of the Correlation Between Gated Cardiac Computed Tomography Detected Vascular Fibrosis and Ease of Transvenous Lead Extraction. Circ Arrhythm Electrophysiol 2022; 15:e010779. [PMID: 36306341 PMCID: PMC10503543 DOI: 10.1161/circep.121.010779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Accepted: 09/30/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Difficulty of lead extraction does not track well with procedural complications, but several small retrospective studies have lead fibrosis on computed tomography as an important indicator of difficult lead extraction. The purpose of the present study was to apply a standardized gated cardiac computed tomography (CT) protocol to assess fibrosis and study it prospectively to examine the need for powered sheaths and risk outcomes. METHODS We performed a prospective, blinded, multicenter, international study at high-volume lead extraction centers and included patients referred for transvenous lead extraction with at least one lead with a dwell time >1 year and ability to receive a cardiac CT. The degree of fibrosis (as measured by amount of lead adherence to vessel wall) was graded on a scale of 1 to 4 by dedicated CT readers in 3 zones (vein entry to superior vena cava, superior vena cava, and right atrium to lead tip). The primary outcome of the study was number of extractions requiring powered sheaths at zone 2 for each fibrosis group. RESULTS A total of 200 patients were enrolled in the trial with 196 completing full gated CT and lead extraction analysis. The primary endpoint of powered sheath (laser and mechanical) sheath use was significantly higher in patients with higher fibrosis seen on CT (scores 3+4; 67.8%) at the zone 2 compared to patients with lower fibrosis (scores 1+2; 38.6%; P<0.001). There were 5 major complications with 3 vascular lacerations all occurring in zone 2 in the study. CONCLUSIONS Gated, contrasted CT can predict the need for powered sheaths by identification of fibrosis but did not identify an absolute low-risk cohort who would not need powered sheaths.

Abstract
Carotid body tumours (CBT), also called carotid paragangliomas, are highly vascular glomus tumours that originate from paraganglionic cells of the carotid body. They are frequently asymptomatic, insidious, and non-secretory in nature. They typically present as a large, non-tender, pulsatile neck mass. Careful evaluation of a neck mass, with the aid of imaging, is necessary to avoid a misdiagnosis. We herein describe a case of a 77-year-old gentleman with a background of chronic B-cell lymphocytic leukaemia, who was found to have a rapidly enlarging, asymptomatic neck mass along with multiple enlarged lymph nodes in the axillae. Given his past medical history, the preliminary diagnosis was Richter’s transformation. However, the characteristic splaying of the internal and external carotid arteries on imaging prompted us to consider the diagnosis of a CBT. The patient was referred to vascular surgeons for surgical excision of the tumour. Histology confirmed that the neck mass was indeed a CBT. Ultrasound-guided core biopsy of the axillary lymph nodes revealed a concomitant Hodgkin-like Richter’s transformation. This case exemplifies how we were able to differentiate between a CBT and nodal mass with the aid of various imaging modalities. An accurate diagnosis allows clinicians to deliver the appropriate management; the treatment for CBT is surgical excision, whereas chemotherapy is the first-line treatment for Richter’s transformation.

Abstract
Allergic rhinitis affects 20% of the population of the UK. It confers a significant health burden upon the individual as it affects the patient's quality of life and is associated with serious comorbidities including asthma, sinusitis and conjunctivitis. Owing to its prevalence, it has a significant economic impact through its effects on education, productivity and use of healthcare resources. This review focuses on the management of allergic rhinitis and potential future treatments, because of the lack of clear national guidelines and because this illness is often misdiagnosed and mismanaged. The article provides a comprehensive overview of allergic rhinitis and illustrates the assessment criteria for various subcategories.

A Meta-Analysis of the Relationship Between Chief Executive Officer Tenure and Firm Financial Performance: The Moderating Effects of Chief Executive Officer Pay and Board Monitoring.

Abstract
Prior empirical research investigating the relationship between chief executive officer (CEO) tenure and firms’ financial performance has shown inconclusive results. Based on arguments of agency and behavioral agency theories, we suggest that this relationship is nuanced and may vary depending on CEO pay and board monitoring. In response to these arguments, we meta-analytically test 385 studies ( n = 1,029,602). We find that CEO tenure is positively related to firms’ financial performance. This positive relationship is enhanced when CEOs receive higher cash compensation or hold more stock ownership. On the other hand, the above positive relationship becomes weaker when CEOs receive higher long-term incentives or when the firm has more independent board directors. These findings suggest that CEO pay and board monitoring, or agency mechanisms in general, can offer new research avenues to help explore boundary conditions of the CEO tenure and firms’ financial performance relationship.

Abstract
AIMS The electrosurgical technology category is used widely, with a diverse spectrum of devices designed for different surgical needs. Historically, hospitals are supplied with electrosurgical devices from several manufacturers, and those devices are often evaluated separately; it may be more efficient to evaluate the category holistically. This study assessed the health economic impact of adopting an electrosurgical device-category from a single manufacturer. METHODS A budget impact model was developed from a U.S. hospital perspective. The uptake of electrosurgical devices from EES (Ethicon Electrosurgery), including ultrasonic, advanced bipolar, smoke evacuators, and reusable dispersive electrodes were compared with similar MED (Medical Energy Devices) from multiple manufacturers. It was assumed that an average hospital performed 10,000 annual procedures 80% of which involved electrosurgery. Current utilization assumed 100% MED use, including advanced energy, conventional smoke mitigation options (e.g. ventilation, masks), and single-use disposable dispersive electrode devices. Future utilization assumed 100% EES use, including advanced energy devices, smoke evacuators (i.e. 80% uptake), and reusable dispersive electrodes. Surgical specialties included colorectal, bariatric, gynecology, thoracic and general surgery. Systematic reviews, network meta-analyses, and meta-regressions informed operating room (OR) time, hospital stay, and transfusion model inputs. Costs were assigned to model parameters, and price parity was assumed for advanced energy devices. The costs of disposables for dispersive electrodes and smoke-evacuators were included. RESULTS The base-case analysis, which assessed the adoption of EES instead of MED for an average U.S. hospital predicted an annual savings of $824,760 ($101 per procedure). Savings were attributable to associated reductions with EES in OR time, days of hospital stay, and volume of disposable electrodes. Sensitivity analyses were consistent with these base-case findings. CONCLUSIONS Category-wide adoption of electrosurgical devices from a single manufacturer demonstrated economic advantages compared with disaggregated product uptake. Future research should focus on informing comparisons of innovative electrosurgical devices.

Abstract
Diabetes mellitus affects over 463 million individuals worldwide. Religious activities such as the Hajj pilgrimage have a major impact on patients with diabetes mellitus, including increasing the risk of hyperglycaemia and hypoglycaemia. This increased risk is due to dietary changes and intense physical activity during pilgrimage while being on antidiabetic medications. Approximately 20% of the pilgrims with underlying illnesses who visit Mecca are diabetic, and complications, such as diabetic ketoacidosis, nonketotic hyperosmolar state, and fatigue/unconsciousness due to hypoglycaemia, have been observed among these patients. Diabetic patients are also at a high risk for foot complications and infections. To avoid any aggravation of the diabetes, a complete biochemical evaluation of the patient must be conducted before Hajj, and the patients must be provided contextualized educational guidance to avert these potential health challenges. This counselling should include the importance of carrying with them at all time their relevant medical history, summaries of the current treatment regimen and emergency snacks. In addition, to reduce the risk of hypoglycaemia, the dosage of insulin should be reduced in selected patients by 20% and that of sulfonylurea should be reduced as needed. Basal insulin and glucagon-like peptide 1 receptor agonists are associated with fewer complications and can be preferentially prescribed. Those patients with type 1 diabetes can continue with the use of insulin pump with suitable education prior to Hajj. For the prevention of foot problems, the use of padded socks and well-fitting shoes is recommended along with an insistence on not walking barefoot. After Hajj, the patient must be followed up, and necessary investigations must be made along with readjustment of insulin dosage in those patients for whom it was reduced. Until the pandemic situation abates, all diabetic patients should avoid making the Hajj journey.

Abstract
As the COVID-19 pandemic has spread across the globe, questions have arisen about the approach healthcare systems should adopt in order to optimally manage patient influx. With a focus on the impact of COVID-19 on the NHS, we describe the frontline experience of a severely affected hospital in close proximity to London. We highlight a protocol-driven approach, incorporating the use of CT in the rapid triage, assessment and cohorting of patients, in an environment where there was a lack of readily available, onsite RT-PCR testing facilities. Furthermore, the effects of the protocol on the effective streamlining of patient flow within the hospital are discussed, as are the resultant improvements in clinical management decisions within the acute care service. This model may help other healthcare systems in managing this pandemic whilst assessing their own needs and resources.

Abstract
Background: Peripherally inserted central catheters and centrally inserted central catheters have numerous benefits but can be associated with risks. This meta-analysis compared central catheters for relevant clinical outcomes using recent studies more likely to coincide with practice guidelines. Methods: Several databases, Ovid MEDLINE, Embase, and EBM Reviews were searched for articles (2006–2018) that compared central catheters. Analyses were limited to peer-reviewed studies comparing peripherally inserted central catheters to centrally inserted central catheters for deep vein thrombosis and/or central line–associated bloodstream infections. Subgroup, sensitivity analyses, and patient-reported measures were included. Risk ratios, incidence rate ratios, and weighted event risks were reported. Study quality assessment was conducted using Newcastle–Ottawa and Cochrane Risk of Bias scales. Results: Of 4609 screened abstracts, 31 studies were included in these meta-analyses. Across studies, peripherally inserted central catheters were protective for central line–associated bloodstream infection (incidence rate ratio = 0.52, 95% confidence interval: 0.30–0.92), with consistent results across subgroups. Peripherally inserted central catheters were associated with an increased risk of deep vein thrombosis (risk ratio = 2.08, 95% confidence interval: 1.47–2.94); however, smaller diameter and single-lumen peripherally inserted central catheters were no longer associated with increased risk. The absolute risk of deep vein thrombosis was calculated to 2.3% and 3.9% for smaller diameter peripherally inserted central catheters and centrally inserted central catheters, respectively. On average, peripherally inserted central catheter patients had 11.6 more catheter days than centrally inserted central catheter patients ( p = 0.064). Patient outcomes favored peripherally inserted central catheters. Conclusion: When adhering to best practices, this study demonstrated that concerns related to peripherally inserted central catheters and deep vein thrombosis risk are minimized. Dramatic changes to clinical practice over the last 10 years have helped to address past issues with central catheters and complication risk. Given the lower rate of complications when following current guidelines, clinicians should prioritize central line choice based on patient therapeutic needs, rather than fear of complications. Future research should continue to consider contemporary literature over antiquated data, such that it recognizes the implications of best practices in modern central catheterization.

Abstract
BACKGROUND Primary Bone Lymphoma can be challenging to interpret even for the experienced reviewer. This case demonstrates the subtle multimodality appearances encountered. CASE SUMMARY a gentleman in his late 70s with one week history of groin pain underwent plain radiography and subsequent further imaging. Only following biopsy was the diagnosis of primary bone lymphoma made for which the patient has received successful treatment. CONCLUSION This case demonstrates the difficulties in identifying lymphoma when seen within the musculoskeletal system. It also provides opportunity to reflect on the importance of initial imaging, good quality history and understanding of differentials.

Abstract
People living with the human immunodeficiency virus (HIV) (PLHIV) are at high risk for tuberculosis (TB), and TB is a major cause of death in PLHIV. Preventing TB in PLHIV is therefore a key priority. Early initiation of antiretroviral therapy (ART) in asymptomatic PLHIV has a potent TB preventive effect, with even more benefits in those with advanced immunodeficiency. Applying the most recent World Health Organization recommendations that all PLHIV initiate ART regardless of clinical stage or CD4 cell count could provide a considerable TB preventive benefit at the population level in high HIV prevalence settings. Preventive therapy can treat tuberculous infection and prevent new infections during the course of treatment. It is now established that isoniazid preventive therapy (IPT) combined with ART among PLHIV significantly reduces the risk of TB and mortality compared with ART alone, and therefore has huge potential benefits for millions of sufferers. However, despite the evidence, this intervention is not implemented in most low-income countries with high burdens of HIV-associated TB. HIV and TB programme commitment, integration of services, appropriate screening procedures for excluding active TB, reliable drug supplies, patient-centred support to ensure adherence and well-organised follow-up and monitoring that includes drug safety are needed for successful implementation of IPT, and these features would also be needed for future shorter preventive regimens. A holistic approach to TB prevention in PLHIV should also include other important preventive measures, such as the detection and treatment of active TB, particularly among contacts of PLHIV, and control measures for tuberculous infection in health facilities, the homes of index patients and congregate settings.

Abstract
Representative compounds from three classes of microporous solids, namely, metal-organic frameworks (MOFs), hybrid ultra-microporous materials (HUMs), and porous-organic polymers (POPs), were investigated for their nitric oxide gas uptake and release behavior. Low-pressure sorption studies indicated strong chemisorption of NO on the free amine groups decorating the MOF UiO-66-NH2 when compared to its non-amine-functionalized parent. The HUMs demonstrated reversible physisorption within the low-pressure regime, but interestingly in one case there was evidence for chemisorption following pressurization with NO at 10 bar. Significant release of chemisorbed NO from the UiO-66-NH2 and one of the HUMs was triggered by addition of acid to the medium, a pH change from 7.4 to 5.4 being sufficient to trigger NO release. An imidazole-based POP exhibited chemisorption of NO at high pressure wherein the ring basicity facilitated both NO uptake and spontaneous release upon contact with the aqueous release medium.

Abstract
BACKGROUND Giant-cell tumours of bone (GCTB) are RANK/RANK-ligand (RANKL) positive, aggressive and progressive osteolytic tumours. Denosumab, a RANKL inhibitor, was FDA-approved for adults and skeletally mature adolescents with unresectable GCTB or when surgical resection is likely to result in severe morbidity. Data on long-term toxicity and activity of denosumab monthly 'GCTB-schedule' (120 mg per 12/year, 1440 mg total dose/year) are lacking. METHODS Patients with GCTB receiving denosumab, 120 mg on days 1, 8, 15, 29 and every 4 weeks thereafter, from 2006 to 2015 treated in two centres were included. Long-term toxicity was evaluated. RESULTS Ninety-seven patients were identified. 43 patients underwent resection of the tumour with a median time on denosumab treatment of 12 months (range 6-45 months). Fifty-four patients had unresectable GCTB's (male/female 23/31, median age 35 years [range: 13-76 years], 26% presented with lung metastases, 31% had primary tumor located to the spine, 63% were relapsed after previous surgery) with a median time on denosumab of 54 months (9-115 months). In the unresectable GCTB group, tumour control and clinical benefits were observed in all patients undergoing denosumab, whereas 40% of patients discontinuing denosumab had tumour progression after a median of 8 months (range 7-15 months). ADVERSE EVENTS Overall, six (6%) patients developed osteonecrosis of jaw (ONJ): 1/43 (2%) in the resectable group, 5/54 (9%) in the unresectable group, with a 5-year ONJ-free survival of 92% (95% CI 84-100). Only patients with prolonged treatment experienced mild peripheral neuropathy (6/54, 11%), skin rash (5/54, 9%), hypophosphataemia (2/54, 4%) and atypical femoral fracture (2/54, 4%). CONCLUSIONS Prolonged treatment with denosumab has sustained activity in GCTB, with a mild toxicity profile. The dose-dependent toxicity observed recommends a careful and strict monitoring of patients who need prolonged treatment. Decreased dose-intensity schedules should be further explored in unresectable GCTB.

Abstract
BACKGROUND According to the Canadian Health Care Association (1), there are 2,577 long-term care ("LTC") facilities across Canada, with the largest proportion (33.4%) located in Ontario. Most studies focus on residents' health, with less attention paid to the health and safety experiences of staff. Given that the work performed in Ontario LTC facilities is very gendered, increasingly racialized, task-oriented, and with strict divisions of labour, this paper explores in what ways some of these factors impact workers' experiences of health and safety. OBJECTIVES The study objectives included the following research question: How are work hierarchies and task orientation experienced by staff? DESIGN AND SETTING This paper draws on data from rapid team-based ethnographies of the shifting division of labour in LTC due to use of informal carers in six non-profit LTC facilities located in Toronto, Ontario. METHODS Our method involved conducting observations and key informant interviews (N=167) with registered nurses, registered practical nurses, personal support workers, dietary aides, recreation therapists, families, privately paid companions, students, and volunteers. Interviews were audio-recorded, transcribed verbatim, and thematically analyzed. For observations, researchers were paired and covered shifts between 7 a.m. and 11 p.m., as well as into the late night over six days, at each of the six sites. Detailed ethnographic field notes were written during and immediately following observational fieldwork. RESULTS Our results indicate that employee stress is linked to the experiences of care work hierarchies, task orientation, and strict divisions of labour between and among various staff designations. CONCLUSION Findings from this project confirm and extend current research that demonstrates there are challenging working conditions in LTC, which can result in occupational health and safety problems, as well as stress for individual workers.

Abstract
The authors report the case of a patient with a background of trapped lung following thoracocentesis who developed an anterolateral intercostal pneumothoracocele resulting in a pneumothorax necessitans (PN). Our purpose is to highlight the pathophysiology and interesting radiological features associated with PN in trapped lung. Our case is particularly unique due to the subacute nature of its presentation in a patient with rheumatoid arthritis and unusual pre-existing lung pathology.

Abstract
OBJECTIVE To present a review of the literature using evidence-based criteria for diagnosis and treatment of malignant growths in the ureteric remnant following nephrectomy for non-malignant disease. METHODS A database search using the key search words was performed, producing a total of 16 articles published between 1952 and 2009. The Oxford Centre for Evidence-Based Medicine classification was used. Statistical significance was tested by Pearson correlation. Demographic data, reason for nephrectomy, symptoms, time to diagnosis since initial nephrectomy, imaging modality and treatment option chosen, as well as histology and overall survival were reviewed. RESULTS Analysis was possible for 33 out of 63 cases reported in the literature. There was a male predominance (82%). Visible, painless haematuria was the presenting symptom in 72% of cases. Open ureterectomy was performed in the majority of patients (85%), while none had laparoscopic surgery. Transitional cell carcinoma was found in 66% of cases. Mean follow-up was 2.7 years. Metastases were detected in 36% and correlated significantly with cancer-specific mortality (95% CI: p < 0.001). Tumour stage, grade and cell type did not correlate significantly with mortality. CONCLUSION Gross, painless haematuria is a feature highly suggestive of neoplastic change. Diagnosis often involves multimodality imaging and endoscopy. Complete ureterectomy with removal of bladder cuff, previously resected endoscopically, is the treatment of choice. Metastases at diagnosis and follow-up carry a worse prognosis.

Abstract
The incidence of concomitant abdominal aortic aneurysm and gastrointestinal malignancy is rare. Current treatment strategies in patients with both lesions remain controversial. It is unclear whether to treat the AAA and gastrointestinal malignancy simultaneously or in a staged manner. In patients with concomitant AAA and gastrointestinal malignancy surgical orthodoxy dictates that the most symptomatic lesion or the most life threatening condition should be treated first, however there is a therapeutic dilemma when neither or both of the lesions are symptomatic .In this review we explore (a) Priority of treatment in patients with concomitant abdominal aortic aneurysm and gastrointestinal malignancy (b) The role of EVAR in the management of abdominal aortic aneurysm and concomitant gastrointestinal malignancy.

Abstract
Menière's disease (MD) is frequently over-diagnosed in both primary and secondary care. This is unfortunate given the significant medical and social implications of such a diagnosis. Difficulties may arise in differentiating the patient with true MD from those individuals with less clearly defined disorders of cochleo-vestibular function. In this review, we suggest a practical evidence based approach to assessment and management of the patient with MD.

Abstract
By using a photonic bandgap (PBG) fiber bundle and a monochrome CCD camera, we experimentally demonstrate an all-fiber spectrometer. A total of 100 Bragg fibers that have complementary and overlapping bandgaps are chosen to compose the fiber bundle. A monochrome CCD is then used to capture the binned image. To reconstruct the test spectrum from a single CCD image, we develop an algorithm based on pseudoinversion of the spectrometer transmission matrix. We demonstrate that the peak center wavelength can always be reconstructed within several percent of its true value regardless of the peak width or position, and that, although the widths of the individual Bragg fiber bandgaps are quite large (60-180nm), the spectroscopic system has a resolution limit of approximately 30nm. Moreover, we conclude that, by minimizing system errors, the resolution can be further improved down to several nanometers in width. Finally, we report fabrication of PBG fiber bundles containing hundreds of fibers using a two-stage drawing technique. This method constitutes a very promising approach toward industrial-strength fabrication of all-fiber spectrometers.

Abstract
Isolated left ventricular noncompaction (ILVNC) is a rare congenital cardiomyopathy characterized by prominent trabeculae, deep intertrabecular recesses, and thickened myocardium with 2 distinct layers (compacted and noncompacted). Clinical characteristics, outcomes, and appropriate therapies remain poorly defined. Data were collected on patients diagnosed with ILVNC by echocardiographic criteria at the Mayo Clinic from 2001 through 2006. These data were entered prospectively into a clinical database and retrospectively analyzed. All-cause mortality, stroke, and development of atrial fibrillation (AF) were compared to community and nonischemic dilated cardiomyopathic (DC) controls. Implantable cardioverter-defibrillator (ICD) therapies were examined. Thirty patients with confirmed ILVNC were included in analyses (mean age at diagnosis 39 +/- 19.5 years, 60% men). Three patients with ILVNC died during follow-up (mean 2.5 +/- 1.2 years) compared to 5 DC and 1 community controls. No mortality difference was observed among these groups (p = 0.42 and 0.054, respectively). No ILVNC deaths were observed in patients with normal LV ejection fraction. New-onset AF was diagnosed in 2 patients with ILVNC, and none was observed in DC controls. Stroke occurred in 2 DC controls and none was observed in patients with ILVNC. ICDs were implanted in 11 patients with ILVNC. No appropriate therapies were identified during follow-up, but 2 patients underwent inappropriate therapies related to AF. In conclusion, mortality in patients with ILVNC is similar to that in DC patients. Deaths were observed only in patients with decreased LV ejection fraction, suggesting that ICD therapy may be reserved for this subgroup. New-onset AF may lead to inappropriate ICD discharges.

Abstract
BACKGROUND The hoarse voice is a common presentation in the adult ENT clinic. It is estimated that otolaryngology/voice clinics receive over 50 000 patients with dysphonia each year. Good vocal function is estimated to be required for around 1/3 of the labour force to fulfil their job requirements. The assessment and management of the patient with a hoarse voice is potentially a complex and protracted process as the aetiology is often multi-factorial. This article provides a guide for the clinician in the general ENT clinic to make a concise, thorough assessment of the hoarse patient and engage in an evidence based approach to investigation and management. METHOD Literature search performed on 4 October 2008 using EMBASE, MEDLINE, Cochrane databases using subject headings hoarse voice or dysphonia in combination with diagnosis, management, investigation, treatment, intervention and surgery. RESULTS General vocal hygiene is beneficial for non organic dysphonia but the evidence base for individual components is poor. There is a good evidence base for the use of voice therapy as first line treatment of organic dysphonia such as vocal fold nodules and polyps. There is little evidence for surgical intervention as first line therapy for most common benign vocal fold lesions. Surgery is, however, the treatment of choice for hoarseness due to papillomatosis. Both CO(2) laser and microdissection are equally acceptable modalities for surgical resection of common benign vocal fold lesions. Laryngopharyngeal reflux is commonly cited as a cause of hoarseness but the evidence base for treatment with gastric acid suppression is poor. Despite the widespread use of proton pump inhibitors for treating laryngopharyngeal reflux, there is high quality evidence to suggest that they are no more effective than placebo. CONCLUSION A concise and thorough approach to assessment in the general ENT clinic will provide the diagnosis and facilitate the management of the hoarse voice in the majority of cases. Voice therapy is an important tool that should be utilised in the general ENT clinic and should not be restricted to the specialist voice clinic. If there is no improvement after initial measures, the larynx appears normal and/or the patient has failed initial speech & language therapy, referral to a specialist voice clinic may be helpful. More research is still required particularly with regard to laryngopharyngeal reflux which is often cited as an important cause of hoarseness but is still poorly understood.

Abstract
BACKGROUND Delay in distinguishing psychogenic nonepileptic seizures (PNES) from epilepsy may result in significant health and economic burdens. Screening tools are needed to facilitate earlier identification of patients with PNES, thereby maximizing cost-effective use of video electroencephalography (VEEG), the expensive gold standard for differentiating PNES from epilepsy. We developed and prospectively validated a self-administered PNES screening questionnaire using variables known to distinguish PNES from epilepsy patients. METHODS Adults referred for inpatient VEEG monitoring at two epilepsy centers were prospectively invited to complete a preliminary 209-item questionnaire assessing demographic, clinical, seizure-related, and psychosocial information that appeared in the literature as potentially useful indicators of PNES. A hybrid neural-bayesian classifier was trained to predict PNES using a sample at one center, and was prospectively validated on a separate set of naive patients from both centers. RESULTS Of 211 enrolled subjects from the training center, 181 met the study criteria for either PNES (n = 48, 27%), epilepsy (n = 116, 64%), or coexisting PNES and epilepsy (n = 17, 9%). Variable reduction procedures identified 53 questionnaire items that were necessary to accurately predict PNES diagnosis. The hybrid classifier predicted PNES diagnosis with 94% sensitivity and 83% specificity at the training center, and 85% sensitivity and 85% specificity at the second center (n = 46; 17 PNES, 26 epilepsy, 3 with coexisting PNES and epilepsy). CONCLUSIONS We developed and prospectively validated a self-administered psychogenic nonepileptic seizure screening questionnaire that could hasten referral for video electroencephalography and reduce the health and economic burdens from delayed diagnosis or misdiagnosis.

Abstract
This report describes a 24-year-old female with left ventricular noncompaction. Cardiovascular magnetic resonance (CMR) imaging demonstrated the characteristic features of noncompaction. We were also able to noninvasively document the presence and extent of myocardial fibrosis depicted on myocardial delayed enhancement (MDE). Magnetic resonance imaging can be performed simply and give much information about the morphologic and tissue characteristics of left ventricular wall in noncompaction. In particular, MDE imaging is useful to demonstrate the associated myocardial scaring that may result in heart failure and arrhythmia.

Abstract
PURPOSE We evaluated 99mtechnetium-mercaptoacetyltriglycine scintigraphy for detecting threshold bladder volume at which upper tract obstruction occurs in patients with bladder dysfunction. MATERIALS AND METHODS A total of 24 patients 19 to 74 years old with severe bladder dysfunction who underwent 99mtechnetium-mercaptoacetyltriglycine scintigraphy and videocystometrogram in a 4-year period were selected for retrospective study. 99mTechnetium-mercaptoacetyltriglycine scintigraphy was done with a full bladder with a mean instilled volume of more than 850 ml saline. In patients in whom an obstructed renal outflow pattern was observed saline was drained at a rate of 100 ml every 5 minutes while dynamic imaging was performed. If results were abnormal, the study was repeated with an empty bladder. Differential function, parenchymal transit time index and outflow efficiency were calculated. RESULTS Of the 24 patients 15 had an obstructed outflow pattern with a full bladder, which was relieved at a bladder volume of less than 390 ml (median 300, range 250 to 600). Only 2 of these 15 patients had a normal vesical end filling pressure of less than 20 cm H2O. There was no obstruction in 9 patients, of whom 5 had increased vesical end filling pressures. Followup in patients who had normal tracer outflow on a full bladder showed no decrease in renal function, while a small decrease was seen in patients who had obstructed outflow on a full bladder. CONCLUSION This novel, full bladder 99mtechnetium-mercaptoacetyltriglycine scintigraphic technique provides the ability to detect bladder volumes at which obstructive outflow patterns develop in patients with severe bladder dysfunction.

Abstract
The objective of this study was to investigate whether low bone mass is directly associated with the severity of coronary atherosclerosis in men and postmenopausal women self-referred for evaluation of coronary atherosclerosis and osteoporosis. Low bone mass was evaluated by measurement of bone mineral density (BMD) using quantitative computerized tomography (QCT). Coronary atherosclerosis was evaluated by measurement of coronary calcium (CC) burden using electron beam computerized tomography (EBCT). Using a cross-sectional design, we tested the hypothesis that osteoporosis and coronary atherosclerosis are correlated, age-dependent processes. Study variables were BMD, CC scores, and other known risk factors for osteoporosis and atherosclerosis. Qualifying for the study were 313 postmenopausal women and 167 men. Men had higher baseline CC scores and higher body mass indexes compared to women. In females, those patients with coronary calcification were older and had significantly lower BMD compared to those without calcification. In males, those patients with coronary calcification were older. By univariate correlation analysis, the degree of coronary calcification was inversely associated with BMD in postmenopausal women (P < 0.0001) but not in men. However, after controlling for age, this association was absent for both men and postmenopausal women. Using multivariate logistic regression analysis in women and men separately, age was the only significant predictor of positive CC status and low BMD. Our study suggests that in postmenopausal women and in men, after controlling for age, osteoporosis and coronary atherosclerosis are independent processes.
