Our goal was to study deglutition of Parkinson??s disease (PD) patients and normal controls (NC) using surface electromyography (sEMG). The study included 15 patients with idiopathic PD and 15 age-matched normal controls. Surface electromyography was collected over the suprahyoid muscle group. Conditions were the following: swallow at once 10 and 20?ml of water and 5 and 10?ml of yogurt of firm consistency, and freely drink 100?ml of water. During swallowing, durations of sEMG were significantly longer in PD patients than in normal controls but no significant differences of amplitudes were found. Eighty percent of the PD patients and 20?% of the NC needed more than one swallow to consume 20?ml of water, while 70?% of the PD patients and none of the NC needed more than one swallow to consume 5?ml of yogurt. PD patients took significantly more time and needed significantly more swallows to drink 100?ml of water than normal controls. We conclude that sEMG might be a simple and useful tool to study and monitor deglutition in PD patients. 相似文献
Aims To establish the prevalence, correlates, comorbidity and treatment gap of alcohol use disorders in the Singapore resident population. Design The Singapore Mental Health Study is a cross‐sectional epidemiological survey. Setting A nationally representative survey of the resident (citizens and permanent residents) population in Singapore. Participants A total of 6616 Singaporean adults aged 18 years and older. Measurements The diagnoses were established using the World Mental Health Composite International Diagnostic Interview (WMH‐CIDI) diagnostic modules for life‐time and 12‐month prevalence of selected mental illnesses including alcohol use disorders. Findings The life‐time prevalence of alcohol abuse and alcohol dependence was 3.1% and 0.5%, while the 12‐month prevalence of alcohol abuse and alcohol dependence was 0.5% and 0.3%, respectively. The life‐time and 12‐month prevalence of alcohol use disorders was 3.6% and 0.8%, respectively. Those with alcohol use disorder had significantly higher odds of having major depressive disorder [odds ratio (OR) 3.1] and nicotine dependence (OR 4.5). Compared to the rest of the population, those with an alcohol use disorder had significantly higher odds of having gastric ulcers (OR 3.0), respiratory conditions (OR 2.1) and chronic pain (OR 2.1). Only one in five of those with alcohol use disorder had ever sought treatment. Conclusions The prevalence of alcohol use disorders is relatively low in the Singapore adult population. Comorbidity with mental and physical disorders is significant, emphasizing the need to screen people with alcohol use disorders for these comorbidities. 相似文献
Few studies have examined the views of policy makers regarding the impact of mental health stigma on the development and implementation of mental health policies. This study aimed to address this knowledge gap by exploring policymakers’ and policy advisors’ perspectives regarding the impact of mental health stigma on the development and implementation of mental health programmes, strategies, and services in Singapore. In all 13 participants were recruited for the study comprising practicing policymakers, senior staff of organisations involved in implementing the various mental health programmes, and policy advisors. Data was collected through semi-structured interviews, which were transcribed verbatim and analysed using reflexive thematic analysis. Data analysis revealed three superordinate themes related to challenges experienced by the policymakers/advisors when dealing with mental health policy and implementation of programmes. These themes included stigma as a barrier to mental health treatment, community-level barriers to mental health recovery, and mental health being a neglected need. Policymakers/advisors demonstrated an in-depth and nuanced understanding of the barriers (consequent to stigma) to mental healthcare delivery and access. Policymakers/advisors were able to associate the themes related to the stigma towards mental illness with help-seeking barriers based on personal experiences, knowledge, and insight gained through the implementation of mental health programmes and initiatives.
To document a rarely reported complication associated with spinal instrumentation and to evaluate the current literature on spinal metallosis and spinal metalloma.
Methods
A local case report is presented. EBSCOhost, PubMed and ScienceDirect databases were used to conduct a systematic review for articles describing spinal metallosis and spinal metalloma.
Results
A total of 836 articles were identified using the terms “metalloma” or “metallosis”. Exclusion of arthroplasty-related abstracts retrieved 46 articles of which 3 full text articles presenting spinal metalloma as a causative pathological finding responsible for neurological signs and symptoms in patients with previous spinal fusion instrumentation were reviewed. Our case is the first described with titanium-composed posterior instrumentation and fifth reported, demonstrating the phenomena of neurological symptoms and signs attributed directly to neural tissue compression by spinal metalloma after spinal instrumentation.
Conclusion
Spinal metallosis can present weeks to years after spinal instrumentation surgery and is a potential cause of neural compression. This process appears to be independent of the instrument composition as metallosis has now been demonstrated in both titanium and stainless steel constructs.
The success rates of craniofacial osseointegrated implants are not uniform throughout the craniofacial area. A better understanding of their clinical behaviour is needed. This article investigates current perspectives on the application of endosseous implants in the restoration of craniofacial defects. An online search was completed for the time period from 1966 to 2007, along with a manual search, to locate relevant peer-reviewed articles and textbooks published in English. A review of published reports of craniofacial application of endosseous implants in irradiated and nonirradiated tissue sites showed a strong correlation between anatomic sites and clinical success. Maxillofacial prosthetic considerations are also reviewed. 相似文献
Type I hilar cholangiocarcinoma is a malignancy of the extrahepatic bile duct for which margin-negative resection with sufficient lymphadenectomy may provide curative treatment. The aim of this video is to highlight the advantages of optical magnification, articulating instruments, and indocyanine green fluorescent cholangiography to demonstrate extrahepatic bile duct resection from the biliary confluence to the intrapancreatic bile duct with comprehensive hilar lymphadenectomy for pathologic staging.
Methods
A 58-year-old male presented with obstructive jaundice and was found to have a biliary stricture arising from the cystic duct and bile duct junction. Endoscopic biopsy of the bile duct confirmed adenocarcinoma. His case was presented at a multidisciplinary tumor conference where consensus was to proceed with upfront robotic en bloc extrahepatic bile duct resection with hilar lymphadenectomy and Roux-en-Y hepaticojejunostomy.
Results
Final pathology demonstrated margin-negative resection of moderately differentiated adenocarcinoma, 1 out of 12 lymph nodes involved with disease, and pathologic stage T2N1M0 (stage IIIC). The patient had no postoperative complications and was discharged home on postoperative day 5. At 6 weeks from his operative date, he was initiated on four cycles of adjuvant gemcitabine/capecitabine, followed by 50 Gray external beam radiation therapy with capecitabine, then four cycles of gemcitabine/capecitabine, completed after 6 months of therapy.
Conclusions
Robotic extrahepatic bile duct resection, hilar lymphadenectomy, and biliary enteric reconstruction is feasible and should be considered for selected cases of bile duct resection.
Cardiovascular risk-prediction models are used in clinical practice to identify and treat high-risk populations, and to communicate risk effectively. We assessed the validity and utility of four cardiovascular risk-prediction models in an Asian population of a middle-income country.
Methods
Data from a national population-based survey of 14,863 participants aged 40 to 65 years, with a follow-up duration of 73,277 person-years was used. The Framingham Risk Score (FRS), SCORE (Systematic COronary Risk Evaluation)-high and -low cardiovascular-risk regions and the World Health Organization/International Society of Hypertension (WHO/ISH) models were assessed. The outcome of interest was 5-year cardiovascular mortality. Discrimination was assessed for all models and calibration for the SCORE models.
Results
Cardiovascular risk factors were highly prevalent; smoking 20%, obesity 32%, hypertension 55%, diabetes mellitus 18% and hypercholesterolemia 34%. The FRS and SCORE models showed good agreement in risk stratification. The FRS, SCORE-high and -low models showed good discrimination for cardiovascular mortality, areas under the ROC curve (AUC) were 0.768, 0.774 and 0.775 respectively. The WHO/ISH model showed poor discrimination, AUC = 0.613. Calibration of the SCORE-high model was graphically and statistically acceptable for men (χ2 goodness-of-fit, p = 0.097). The SCORE-low model was statistically acceptable for men (χ2 goodness-of-fit, p = 0.067). Both SCORE-models underestimated risk in women (p < 0.001).
Conclusions
The FRS and SCORE-high models, but not the WHO/ISH model can be used to identify high cardiovascular risk in the Malaysian population. The SCORE-high model predicts risk accurately in men but underestimated it in women. 相似文献
Haemophilus influenzae type b (Hib) conjugate vaccines have significantly limited Hib's disease impact in every country where it was introduced. We previously estimated invasive Hib disease incidence in Singapore at ∼4.4 per 100,000 children <5 years (from 1994 to 2003, period 1), but the vaccine was not included in the national childhood immunization schedule until May 2013 (although it was available privately). The current study aims to describe changes in Hib disease incidence and vaccine coverage prior to the introduction of the vaccine.
Methodology
We retrospectively reviewed all invasive Hib cases from January 2004 to December 2012 (period 2) and estimated population-based incidence rates. Vaccine coverage was estimated from vaccine sales for 1994–2003, and from National Immunisation Registry for 2004–2010.
Results
There were 8 cases of invasive Hib disease in period 2, of whom 5 were <5 years. Invasive Hib incidence for period 2 was 0.57 per 100,000 children <5 years, representing an 86.4% reduction compared to period 1 (rate ratio 0.14, 95% confidence interval 0.06–0.26). However, for the later part of period 2 (2008–2012), incidence was 0.2 per 100,000 children <5 years; this represented a 95% reduction from period 1 (rate ratio 0.05, 95% confidence interval 0.01–0.18). Between periods 1 and 2, national Hib vaccine coverage rose from 22% to >80%, with >99% of children receiving combination Hib-containing vaccines.
Conclusions
Childhood invasive Hib disease has nearly disappeared from Singapore, despite the absence of universal mass vaccination. We believe this is likely due to excellent uptake of combination vaccines. 相似文献
