Methods: Four adult patients with refractory OCD were implanted with Model 3387 leads bilaterally in an area of VC/VS. Postoperative test stimulation was performed at least 2 weeks after surgery. We performed double-blinded postoperative test stimulation with different contact and voltage. The relationship of stimulation-induced smile/laughter and chronic response was examined.
Results: Patients presented smile, laughter, euphoria, increased heart rate, increased blood pressure, smell, chest vibration, dizziness, nausea, heat, or increased sexual drive during acute stimulation. We found that the higher the percentage Selleck MK2206 of smile/laughter
(34.3%, 31.3%, 56.3%, and 12.5% for four cases), the greater SBE-β-CD in vitro the reduction in the Yale-Brown Obsessive Compulsive Scale (30.6%, 38.9%, 58.8%, and 7.7% respectively at 15-month DBS).
Conclusion: This study showed that acute DBS of the VC/VS might cause mood change, cardiovascular, sensory, or motor effects. These effects were transient or habituated over six months. We suggest stimulation-induced smile/laughter may be a possible predictor for long-term DBS outcome. Larger studies, genetic studies, and imaging studies are needed to evaluate the effects of different parameters and possible predictors in the treatment of OCD.”
“Early and effective
treatment of chronic inflammatory demyelinating polyneuropathy (CIDP) is important to minimize axonal degeneration that occurs secondary to demyelination. The disease course is invariably chronic, so long-term treatment is often required, and adverse effects and costs are important
considerations in devising a treatment plan. CIDP responds to prednisone, but long-term treatment can result in significant adverse effects. Azathioprine, mycophenolate mofetil, and cyclosporine can be used as steroid-sparing Crenolanib solubility dmso agents and may facilitate more rapid and successful tapering of prednisone. Intravenous immunoglobulin (IVIg) and plasma exchange are also effective in the treatment of CIDP and can be used in patients who are unresponsive to prednisone or develop steroid-related adverse effects. IVIg may also be used as a first-line treatment, but its cost can be a limiting factor. A few uncontrolled studies have suggested that pulsed weekly methylprednisolone is both effective and well tolerated in the long-term treatment of CIDP. Treatments based on rituximab or cyclophosphamide have also been used in resistant disease.
Variants of CIDP have been described on the basis of their association with specific antibodies or immunoglobulins and their response to specific immunomodulatory treatments. Multifocal motor neuropathy with conduction block responds to IVIg in the majority of patients. However, weakness may slowly worsen over time, and some patients become unresponsive.
