The object of this study was to determine the association between tender point pain ratings, tender point counts and distress in people with fibromyalgia and to review the pharmacotherapy of fibromyalgia. Demographic, psychosocial, and health status information was collected from 316 health maintenance organization members with fibromyalgia. A manual tender point exam was conducted. ⋯ Tender point pain ratings and counts predicted a small but significant amount of variance in distress. In addition, FMS involves at least four rather distinct factors, one of which is related to tender points. Pharmacotherapeutic management is provided on a patient-specific basis including pharmacokinetics, pharmacodynamic, pathophysiologic, and psychosocial needs designed and modulated for each individual patient.

The objective of this study was to evaluate the effect of hormone replacement therapy (HRT) regimens on left ventricular diastolic function by using mitral pulsed wave Doppler (MPWD) and tissue Doppler velocities (TDE). Seventy-eight postmenopausal women with normotensive and impaired diastolic left ventricular filling were included in the study. All the patients began a six-cycle HRT course. ⋯ TDE parameters were independent from the preload and did not produce pseudonormal pattern. HRT may cause increase in the blood volume and produce pseudonormal pattern in transmitral flow. In that case, TDE may be a beneficial method for evaluation of diastolic function.

Torsade de pointes is a malignant dysrhythmia that has been reported in a variety of clinical settings and associated with several pharmacologic agents. Patients with a prolonged QTc for heart rate are at higher risk for the development of this arrhythmia. We review the literature supporting the relationship of haloperidol to the development of this malignant dysrhythmia. Clinicians in the critical care setting should be aware of potentially lethal drug-induced ventricular tachydysrhythmias such as torsade de pointes.

Fomepizole (Antizol) was recently approved by the US Food and Drug Administration for treatment of methanol poisoning. By inhibiting the hepatic enzyme alcohol dehydrogenase, it presents formation of toxic metabolites with far fewer consequences than traditional ethanol therapy. It appears that fomepizole will become standard therapy for methanol intoxication as it is for ethylene glycol poisoning.
