To determine the effect of diabetes on the development of axonal degeneration after acute nerve compression, the mobilized peroneal nerves of rats with streptozotocin-induced diabetes and of control rats were compressed at 150 mmHg (1 mmHg = 133 Pa) for 30 min by using specially devised cuffs. At three intervals after compression--3 days, rats diabetic for 31 wk; 14 days, diabetic for 6 wk; and...
Erythropoietin (EPO) is both hematopoietic and tissue protective, putatively through interaction with different receptors. We generated receptor subtype-selective ligands allowing the separation of EPO's bioactivities at the cellular level and in animals. Carbamylated EPO (CEPO) or certain EPO mutants did not bind to the classical EPO receptor (EPOR) and did not show any hematopoietic activity ...
Foot ulcers can be caused by arterial insufficiency, diabetes mellitus, neuropathy, musculoskeletal disorders, or injury. The clinical features of an ulcer—such as site, shape, edge, base, and state of the surrounding tissues—often give some indication of its aetiology and aid in further management and treatment. Ulceration of the foot is seen in some patients with venous disease but has not be...
The onodi cell is a posterior ethmoidal cell that is pneumatized laterally or superiorly to the sphenoid sinus with close proximity to the optic nerve. A mucocele, a benign, expansile, cyst-like lesion of the paranasal sinuses, may uncommonly involve the onodi cell causing compression of the optic nerve and nearby structures. In this paper, we report a rare case of onodi cell mucocele causing o...
Type 2 superior labral anterior to posterior (SLAP) lesion is a common cause of shoulder pain requiring surgical operation. SLAP tears are often associated with paralabral cysts, but they rarely cause nerve compression. However, we experienced two cases of type 2 SLAP-related paralabral cysts at the spinoglenoid notch which were confirmed as isolated nerve entrapment of the infraspinatus branch...
Nerve pathologies are a common cause of forefoot pain and include diverse conditions with similar symptoms. The symptoms are characteristic of sensory nerve disorders and differ from other musculoskeletal conditions. Morton’s intermetatarsal neuroma is a compression neuropathy of the common digital nerve (Fig. 1). It is most commonly seen in the third intermetatarsal space, but it also can be s...
Entrapment neuropathy is a group of clinical disorders involving compression of a peripheral nerve and interference with nerve function mostly through traction injury. We have investigated the chronic compression of peripheral nerves as an experimental procedure for detecting changes in ultrastructural nerve morphology. Adult hamsters (Mesocricetus auratus, N = 30) were anesthetized with a 25% ...
OBJECTIVE In this article, the presentation, pathophysiology, diagnosis, treatment, and complications of lipomas of the hand are reviewed and evaluated. METHODS A thorough review of the literature is completed, and a series of 13 patients are summarized and briefly examined. RESULTS Lipomas may present as asymptomatic tumors or produce concerning signs and symptoms such as muscular atrophy ...
Hypoglossal nerve injury is a very rare complication of anaesthesia airway management. The cause argued to this lesion is neuropathy of this nerve provoked by its compression due to inflation of the cuff within the larynx or damage secondary to hyperextension of the neck during a difficult intubation. Although most cases describe Tapia ́s syndrome with hypoglossus and recurrent laryngeal nerve p...
A patient presented with acute-onset, painless, unilateral enlargement of the tongue. Steroid treatment for angioedema was ineffective, and a biopsy of an apparent mass of the tongue base showed normal tissue. Subsequent magnetic resonance imaging showed enlargement, enhancement, asymmetric T2 hyperintensity of the left half of the tongue, and dissection of the left cervical internal carotid ar...
