Combined nerve conduction index in diabetic polyneuropathy.

Unlabelled: Diabetic polyneuropathy can be confirmed by nerve conduction studies. The data can be analyzed in the form of a combined index instead of individual parameters.

Methods: The combined index included five parameters of nerve conduction studies commonly used for evaluation of polyneuropathies.

Acute axonal polyneuropathy with predominant proximal involvement: an uncommon neurological complication of bariatric surgery.

Bariatric surgery is frequently indicated in the treatment of morbid obesity. Previously unreported complications have been associated to this surgery; among them, neurological complications have gained attention. We report the case of a 25-year-old man submitted to gastric surgery for treatment of morbid obesity who developed, two months after surgery, acute proximal weakness in lower limbs.

[Bilateral hemifacial spasm: case report].

Bilateral hemifacial spasm (BHS) is a rare focal movement disorder often associated with vascular compression of both facial nerves. The contractions are usually asymmetric and asynchronous. Typically, one side is affected first and there is a long but variable interval for the symptoms on the other side to occur.

A case of primary spinal myoclonus: clinical presentation and possible mechanisms involved.

Spinal myoclonus is a rare movement disorder characterized by myoclonic involvement of a group of muscles supplied by a few contiguous segments of the spinal cord. Structural lesions are usually the cause, but in primary spinal myoclonus the etiology remains unknown. We present the case of a 26-year-old woman with cervical spinal myoclonus in which both clinical and electromyographic findings pointed to the segment C1-C3 as the origin of the myoclonus.
