Investigation of fluoroquinolone-induced myalgia using (31)P magnetic resonance spectroscopy and in vitro contracture tests.

Objective: To investigate muscle function in patients with severe myalgia resulting from fluoroquinolone (FQ) treatment. We used histology, in vitro contracture tests (IVCTs), and (31)P magnetic resonance spectroscopy ((31)P MRS) to explore muscle contraction and metabolism.

Methods: We studied 3 patients with myalgia, hyperalgia tendinopathy, and arthralgia following FQ treatment and 3 normal subjects after taking FQs.

[Lead poisoning in adults. Experience of the Poison Control Center of Marseille from 1993 to 2000].

Objective: Report the experience of the Marseille's anti-poison center with lead poisoning adults.

Patients And Methods: Between 1993 and 2000, 45 adults patients consulted the poison Centre of Marseille for a history of lead exposure (9 women, 36 men, average age 44 YO, between 22 an 76 YO). The lead sources were mostly occupational (welding, heavy metal industries.

Malignant hyperthermia susceptibility revealed by myalgia and rhabdomyolysis during fluoroquinolone treatment.

Fluoroquinolones cause myalgia, but this complication is not clearly documented. We describe a patient who developed myalgia and rhabdomyolysis during fluoroquinolone treatment. The patient was a 33-year-old man treated with norfloxacin for common cystitis.

Cannabis arteritis revisited--ten new case reports.

The purpose of this paper was to revisit the old concept of cannabis arteritis first described in the 1960s and report 10 new cases. Ten male patients, with a median age of 23.7 years developed subacute distal ischemia of lower or upper limbs, leading to necrosis in the toes and/or fingers and sometimes to distal limb gangrene.
