OBJECTIVE
Pathomechanisms of work-related myalgia are poorly understood. Myalgia is thought to be caused by excitation of nociceptors present in the muscular tissue but not in the muscle fiber itself. Muscle contraction in combination with hypoxia is known to excite nociceptors. Morphologic analysis
Muscle fiber degeneration and regeneration, inflammation in the intramuscular connective tissue and hypoxia in resting muscle are not necessarily associated with pain. However, when sustained or dynamic muscle contractions are performed in an ischaemic muscle, severe pain develops. In the chronic
Muscle fibre degeneration and regeneration, inflammation in intramuscular connective tissue and hypoxia in resting muscle are not necessarily associated with pain. However, when sustained or dynamic muscle contractions are performed in an ischaemic muscle, severe pain develops. In the chronic muscle
A 25-year-old man developed severe shortness of breath, constricting chest pressure, chest pain, cough and myalgia following acute exposure to a waterproofing aerosol that contained trichloroethane. He became febrile and developed a small area of atetectasis with significant hypoxemia. Recovery was
OBJECTIVE
Muscle pain syndromes are extremely frequent cause of chronic disability, and a muscle biopsy is often performed to achieve a diagnosis when myalgia has a myopatic origin. Instead, the role of muscle biopsy in fibromyalgia is controversial. This review examines the reported studies with
In the spring and summer of 1981, an epidemic of a new illness now referred to as the toxic oil syndrome occurred in central and northwestern Spain, resulting in some 20,000 cases, 12,000 hospital admissions and greater than 300 deaths in the 1st year of the epidemic. The initial onset of illness

J Strength Cond Res 32(8): 2174-2182, 2018-This study aimed to determine whether performing resistance exercise in hypoxia

Diabetic muscle infarction is a rare condition which may present to a rheumatologist. It was first reported in 1965. Two illustrative cases are described here and the mechanisms of pathogenesis discussed. Analysis of the published data, results of the muscle biopsies, and a technetium-99m sestamibi
Mushrooms of the genus Psilocybe frequently are ingested by recreational drug users for their hallucinogenic effects. We present the case of a 30-year-old man who allegedly received an intravenous injection of an extract of Psilocybe mushrooms. His clinical course was characterized in part by
OBJECTIVE
To investigate the clinical features of patients with microscopic polyangiitis (MPA) and alveolar hemorrhage (AH), so as to raise the physicians' understanding of this condition.
METHODS
The clinical data of 15 MPA patients combined with AH, who were hospitalized in Peking Union Medical
Although mechanisms underlying chronic muscle pain are poorly understood, one prevalent theory is that it is due, in part, to localized hypoxia. The purpose of this study was to evaluate this theory using non-invasive near-infra-red spectroscopy that monitors relative changes in intramuscular
Psychological and social factors at work may contribute to musculoskeletal disorders by the following processes: (i) Direct pathogenic effects by affecting physiological mechanisms, such as muscle blood vessels and hormonal secretion; (ii) by altering work procedures and thereby altering the
BACKGROUND
The outcome of patients with influenza A 2009 (H1N1)v virus infection taking into account hospital type has not been elucidated.
OBJECTIVE
To compare risk factors, clinical features and outcome of patients admitted to 3 public hospitals with different levels of
Allo-SCT can result in long-term remission in patients with multiple myeloma (MM), although its overall role in disease management remains controversial. We evaluated lenalidomide monotherapy response and tolerability among 18 patients with MM who progressed or relapsed after Allo-SCT, who were
