Introduction: Clodronic acid is a non-nitrogen-containing bisphosphonate largely used from some decades in the prevention and treatment of postmenopausal and secondary osteoporosis. In addition to antiresorptive activity, clodronate has shown anti-inflammatory and analgesic properties, and modulatory effects on bone and cartilage metabolism.

Evidence Acquisition: A literature review has been conducted to characterize the mechanism of action of clodronate and to retrieve available evidence about the use of clodronate in primary and secondary osteoporosis, and its potential role in other musculoskeletal conditions and orthopedic surgery.

Background: Corticosteroid treatment is considered the 'gold standard' for Duchenne muscular dystrophy (DMD); however, it is also known to induce osteoporosis and thus increase the risk of vertebral fragility fractures. Good practice in the care of those with DMD requires prevention of these adverse effects. Treatments to increase bone mineral density include bisphosphonates and vitamin D and calcium supplements, and in adolescents with pubertal delay, testosterone. Read More

Polymyositis-dermatomyositis is a rare systemic autoimmune disease which belongs to the class of idiopathic inflammatory myopathies. The disease exhibits high inter-individual variability, but chronic myositis is a common feature. As different manifestations often appear in atypical forms, establishing the precise diagnosis can be rather complicated. Read More

Corticosteroids constitute an ideal treatment for various inflammatory and autoimmune disorders due to their anti-inflammatory and immunomodulatory actions. However, corticosteroids have a considerable number of side effects, including hypertension, diabetes, lipid disorders, sleep apnea, osteoporosis, myopathy, and disorders of coagulation and fibrinolysis, which are components of Cushing's syndrome (CS). Corticosteroid-induced side effects are dependent on the formulation, route, dose, and time of exposure. Read More

Intralesional and intra-articular corticosteroids are commonly used therapies in the fields of dermatology, orthopedic surgery and rheumatology. The authors present the case of a 32-year-old female who received intra-articular corticosteroids for de Quervain's tendonitis and developed bilateral hypopigmented patches near the areas of injection. Unilateral linear extension of the hypopigmentation was subsequently noted, presumably secondary to venous or lymphatic uptake of corticosteroid crystals. Read More

Department of Respiratory Medicine, Kyoto University Graduate School of Medicine, Kyoto, Japan.

Background: Therapy-resistant asthma is an important clinical problem. However, before considering asthma truly therapy resistant, it is essential to exclude diagnoses that may masquerade as therapy-resistant asthma, such as vocal cord dysfunction and recurrent aspiration, as well as factors related to loss of asthma control, including poor compliance, exposure to allergens, and sinusitis. Corticosteroid-induced myopathy may be an unrecognized but potentially important consideration in both settings. Read More

Corticosteroids represent the most important and frequently used class of anti-inflammatory drugs and are the reference therapy for numerous neoplastic, immunological and allergic diseases. However, their substantial efficacy is often counter-balanced by multiple adverse events. These corticosteroid-induced adverse events represent a broad clinical and biological spectrum from mild irritability to severe and life-threatening adrenal insufficiency or cardiovascular events.

Objective: Physiopathology of critical illness polyneuromyopathy was investigated in several animal-based models. Electrophysiologic approach was achieved in denervated and corticosteroid-induced myopathy; other models based on sepsis or inflammatory factors (zymosan, cytokines) were also used but did not consider voltage-gated sodium channel implication in neuromuscular weakness. We have studied electrophysiologic effects of chronic sepsis on an intact neuromuscular rat model with special consideration to the subtypes of sodium channels involved. Read More

During the past 2 decades, heart transplantation has evolved from an experimental procedure to an accepted life-extending therapy for patients with endstage heart failure. However, with dramatic improvements in organ preservation, surgery and immunosuppressive drug management, short term survival is no longer the pivotal issue for most heart transplant recipients (HTR). Rather, a return to functional lifestyle with good quality of life is now the desired procedural outcome. Read More
