This paper describes a non-invasive quantitative method for the diagnosis of neuromuscular disorders using surface EMG (sEMG). We found sEMG to be a reliable method that can be used to differentiate neuropathic and myopathic patients from the normal subjects. The multivariate discriminant analysis of sEMG data assisted in separating myopathic from(More)
The EMG information obtained by surface recording is compared to needle derived data processed in an identical manner. Such quantitative analysis of EMG activity has been undertaken using needle electrodes and is a well recognised technique for clinical purposes (16). Results of a study comparing data collected simultaneously by surface and needle(More)
BACKGROUND Leptospirosis is endemic in both urban and rural areas of Sri Lanka and there had been many out breaks in the recent past. This study was aimed at validating the leptospirosis surveillance case definition, using the Microscopic Agglutination Test (MAT). METHODS The study population consisted of patients with undiagnosed acute febrile illness(More)
BACKGROUND Melioidosis has become an emerging infection in Sri Lanka; a country which is considered non endemic for it. Paraplegia due to Burkholderia pseudomallei is a very rare entity encountered even in countries where the disease is endemic. There are no reported cases of transverse myelitis due to melioidosis in Sri Lankan population thus we report the(More)
BACKGROUND Lemierre's syndrome is a rare condition characterized by thrombophlebitis of internal jugular vein, septicemia and septic metastatic infection of different organs. It is preceded by an oropharyngeal infection by anaerobic organisms. Community-acquired methicillin-resistant Staphylococcus aureus is now emerging as a causative organism in(More)
BACKGROUND Leptospirosis has a varied clinical presentation with complications like myocarditis and acute renal failure. There are many predictors of severity and mortality including clinical and laboratory parameters. Early detection and treatment can reduce complications. Therefore recognizing the early predictors of the complications of leptospirosis is(More)
BACKGROUND Guillain-Barré syndrome is an immune mediated acute inflammatory polyradiculo-neuropathy involving the peripheral nervous system. Commonest presentation is acute or subacute flaccid ascending paralysis of limbs. Rarely autonomic dysfunction can be the presenting feature of Guillain-Barré syndrome. Raynaud's phenomenon, although had been described(More)
Berardinelli-Seip congenital lipodystrophy (BSCL) is a rare autosomal recessive disorder of generalised lipoatrophy, characterised by the absence of functioning adipocytes, with lipid being stored in muscles, the liver and the pancreas. The usual presentation is in adulthood, with manifestations of insulin resistance, hypertriglyceridaemia and liver(More)
Acquired angioedema is a rare but recognized manifestation of lymphoproliferative disorders due to deficiency in C1 esterase inhibitor. Normal level of C1 esterase inhibitor proteins in association with angioedema due to lymphoproliferative disease is a rare and an uncommon finding caused by antibodies produced from the underlying disease. Antibodies cause(More)
