INTRODUCTION: Fibromyalgia syndrome (FMS) is a common but controversial condition. There appears to be different levels of belief of its existence and awareness. We set out to explore the variations of perceptions and awareness of this condition among rheumatologists from Malaysia and Singapore.
METHODS: 48 rheumatologists from Malaysia (28) and Singapore (20) were approached to participate in this survey by answering a specific questionnaire regarding their belief in FMS. 23 respondents from Malaysia and 20 from Singapore completed the questionnaire.
RESULTS: 91 percent of Malaysian rheumatologists and 95 percent of the Singaporean believe that FMS is a distinct clinical entity and that this condition is considered an illness rather than a disease. 87 percent and 90 percent of rheumatologists from Malaysia and Singapore, respectively, believe that FMS is a mixture of medical and psychological illness. However, not many of those in the university setting include FMS in their undergraduate teaching. 87 percent and 80 percent of the respondents from Malaysia and Singapore, respectively, also ordered blood tests to exclude other serious pathologies, and 100 percent of the respondents from both countries also prescribed some form of drugs to their FMS patients.
CONCLUSION: This study confirmed that there was a variation of perceptions and knowledge of FMS among rheumatologists from Malaysia and Singapore. The majority of rheumatologists recognise that FMS is a distinct clinical entity, and is diagnosed by excluding other well-defined clinical diseases through a combination of clinical evaluation and screening tests.
BACKGROUND: Fibromyalgia syndrome (FMS) is a common but controversial condition. There appears to be different level of belief of its existence and awareness. We set out to explore the variations of perceptions and awareness of this condition among rheumatologists from the Southeast Asia (SEA) region.
METHODS: One hundred eight rheumatologists from the participating countries; 28 from Malaysia, 20 from Singapore, 26 from Thailand, 2 from Brunei, and 42 from Indonesia were approached to participate in this survey by answering specific questions regarding their beliefs in relation to FMS; 82% respondents from Malaysia, 100% from Singapore, 92% from Thailand, 100% from Brunei, and 90% from Indonesia completed the questionnaires.
RESULTS: Most rheumatologists (92.5%) from SEA believe that FMS is a distinct clinical entity, and also this condition is considered an illness rather than a disease. Eighty-seven percent rheumatologists from SEA believe that FMS is a mixture of medical and psychological illness, 9% believe that FMS is primarily a psychological illness, and 3% believe that it is a medical illness. Only 60% of those in a university setting include FMS in their undergraduate teaching. Eighty-five percent of the respondents ordered blood tests to exclude other serious pathologic conditions, and 100% of the respondents from SEA countries also prescribed some form of drugs to FMS patients.
CONCLUSION: FMS is apparently seen worldwide. This study confirmed that there was a variation of perceptions and knowledge of FMS among rheumatologists from SEA countries. However, most rheumatologists agreed that FMS is a distinct clinical entity with a mixture of medical and psychological factors.
Fibromyalgia is an intense musculoskeletal pain causing sleep, fatigue, and mood problems. Sleep studies have suggested that 70%-80% of fibromyalgia patients complain of non-restorative sleep. The abnormalities in sleep have been implicated as both a cause and effect of the disease. In this paper, the electroencephalogram (EEG) signals of sleep stages 2 and 3 are used to classify the normal and fibromyalgia classes automatically. We have used various nonlinear parameters, namely sample entropy (SampEn), fractal dimension (FD), higher order spectra (HOS), largest Lyapunov exponent (LLE), Kolmogorov complexity (KC), Hurst exponent (HE), energy, and power in various frequency bands from the EEG signals. Then these features are subjected to Student's t-test to select the clinically significant features, and are classified using the support vector machine (SVM) classifier. Our proposed method can classify normal and fibromyalgia subjects using the stage 2 sleep EEG signals with an accuracy of 96.15%, sensitivity and specificity of 96.88% and 95.65%, respectively. Performance of the developed system can be improved further by adding more subjects in each class, and can be employed for clinical use.
Neuropathic pain is a common phenomenon that affects millions of people worldwide. Maxillofacial structures consist of various tissues that receive frequent stimulation during food digestion. The unique functions (masticatory process and facial expression) of the maxillofacial structure require the exquisite organization of both the peripheral and central nervous systems. Neuralgia is painful paroxysmal disorder of the head-neck region characterized by some commonly shared features such as the unilateral pain, transience and recurrence of attacks, and superficial and shock-like pain at a trigger point. These types of pain can be experienced after nerve injury or as a part of diseases that affect peripheral and central nerve function, or they can be psychological. Since the trigeminal and glossopharyngeal nerves innervate the oral structure, trigeminal and glossopharyngeal neuralgia are the most common syndromes following myofascial pain dysfunction syndrome. Nevertheless, misdiagnoses are common. The aim of this review is to discuss the currently available diagnostic procedures and treatment options for trigeminal neuralgia, glossopharyngeal neuralgia, and myofascial pain dysfunction syndrome.
