Clinical TrialPost-stroke spasticity management with repeated botulinum toxin injections in the upper limb.
Although the botulinum toxin A (BTX-A) treatment has proved effective in spasticity management, no information is available with regard to the effects of repeated injections over time. ⋯ This investigation is relevant clinically because repeated BTX-A injections show unchanging effectiveness in the management of focal spasticity after stroke.

Maximum insufflation capacity: vital capacity and cough flows in neuromuscular disease.
To investigate the relationships between vital capacity (VC), maximum insufflation capacity (MIC), and both unassisted and assisted peak cough flows (PCFs). ⋯ The greater the MIC VC difference, the greater the PCF, and, thereby, the ability to expel airway mucus and avert respiratory complications. The lower the VC, the greater the percent increase in MIC and the greater the percent increase in assisted PCF. Maximal insufflations are extremely important to increase PCF for patients with neuromuscular conditions who have VCs of < 1500 ml.

Multicenter StudyEffect of history and exam in predicting electrodiagnostic outcome among patients with suspected lumbosacral radiculopathy.
To determine the extent to which the history and physical examination predict the outcome of the electrodiagnostic (EDX) evaluation in patients with suspected lumbosacral radiculopathy. ⋯ In a population of patients referred for an EDX study, the history and physical examination alone cannot reliably predict electrodiagnostic outcome.

Randomized Controlled Trial Clinical TrialTreatment of myofascial pain.
To investigate the effectiveness of ultrasound treatment and trigger point injections in combination with neck-stretching exercises on myofascial trigger points of the upper trapezius muscle. ⋯ Patients with myofascial pain syndrome had higher scores for anxiety than for depression. When combined with neck stretching exercises, ultrasound treatment and trigger point injections were found to be equally effective.

Subcutaneous heparin is commonly used as a prophylaxis against deep venous thrombosis in a wide variety of hospitalized patients. As with most medications, heparin has a significant side effect profile; heparin-induced hyperkalemia is an unusual but well described side effect. To increase awareness of heparin-induced hyperkalemia and of those patients at greatest risk, we present two cases of documented hyperkalemia induced by heparin and reconfirmed by drug rechallenge.
