Pain and small-fiber affection in hereditary neuropathy with liability to pressure palsies (HNPP).

Scand J Pain 2019 12;20(1):61-68

Section of Clinical Neurophysiology, The Department of Neurology, Oslo University Hospital - Rikshospitalet, Institute of Clinical Medicine, University of Oslo, Oslo, Norway.

Background and aims Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal - dominant hereditary neuropathy caused by a deficiency in the peripheral protein PMP-22, due to deletion on chromosome 17p11,2 or in some rare cases point mutations in the PMP-22 gene. The clinical picture is characterized by recurrent mononeuropathies in nerves which frequently may be exposed to pressure, such as the median, ulnar, radial and peroneal nerves or also a more general neuropathy. Although pain is reported to be an unusual clinical symptom, there have been reports of pain in a surprisingly high proportion of these patients. Read More

"Clip Anchor-Assisted Coil Embolization" for Endovascular Parent Artery Occlusion of Intracranial Traumatic Aneurysm.

J Stroke Cerebrovasc Dis 2019 Nov 14;28(11):104374. Epub 2019 Sep 14.

Department of Neurosurgery, Amagasaki General Medical Center, Amagasaki, Osaka Japan.

Traumatic cerebral aneurysms are histologically dissecting aneurysms or pseudoaneurysms, thus requiring parent artery occlusion for cure. Combination of endovascular parent artery occlusion and extracranial-intracranial bypass is considered optimal to obtain complete obliteration of the aneurysm and to avoid hemodynamic hypoperfusion. However, endovascular parent artery occlusion of the supraclinoid internal carotid artery (ICA) is at risk of ischemic complications due to distal coil protrusion to adjacent perforating arteries or distal embolism of the thrombi generated in the coil mass.

An Unusual Radial Neuropathy.

J Orthop Sports Phys Ther 2019 07;49(7):558

A 23-year-old woman presented to her physician for left forearm pain of insidious onset, inability to extend the wrist, and numbness in the dorsal hand. An electromyogram (EMG) and nerve conduction study (NCS) demonstrated radial neuropathy, while magnetic resonance imaging (MRI) of the left elbow/forearm, performed 2 months later, revealed edema and atrophy of the wrist extensor muscles, but no compressive lesion. Following a lack of improvement and consultation with an orthopaedic surgeon, a second, more detailed EMG/NCS was performed, revealing a severe radial motor and sensory neuropathy, with compression between the lateral and long heads of the triceps.
