conclusions bilateral anterior shoulder dislocation is very rare. the excessive traction force during closed reduction may lead to nerve palsy. clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. introduction unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. however, simu...

choroid plexus papillomas are rare intracranial tumors, accounting for less than 1% of all intracranial tumors in adults. however, they are relatively more common in children and constitute 1.5 to 4% of childhood intracranial tumors. in children, choroid plexus papillomas are predominately located in the lateral ventricles, followed by the forth and third ventricles and, rarely, in the cerebell...

Brachial plexus block using local anaesthetics is used widely for upper limb surgery. Proper identification of the nerve bundle is very important to inject local anaesthetic. Methods like paresthesia technique, nerve locator technique and ultrasound is used to identify the nerve bundle. The oldest is the parestheia technique and it causes few complications like inadequate block, failed block, i...

Stanniocalcin (STC) is a 28 kD glycoprotein hormone originally found in bony fish in which it regulates calcium/phosphate homeostasis and protects against hypercalcemia. The recently characterized mammalian STC shows about 70% homology with fish STC. The epithelial cells of proximal tubuli in human and rat kidney and brain neurons have been found to express STC. Here we show that the epithelium...

In Microtus montanus infected with T. b. gambiense, electron microscopic examination of lymph nodes, spleen, liver, heart, choroid plexus and brain demonstrated extravascular populations of trypanosomes distributed throughout interstitial spaces, accompanied by a moderate cellular infiltration of plasma cells. The trypanosomes exhibited numerous profiles; some were dividing, others were in diff...

A 72-yr-old patient was to undergo a left lumbar plexus block by the posterior approach to achieve postoperative analgesia after hip replacement. The block failed after three unsuccessful attempts to identify nerve structures and a fascia iliaca compartment block was performed. Postoperatively the patient received enoxaparin and then phenylindanedione for thromboprophylaxis. She was re-admitted...

neurolymphomatosis is a rare manifestation of non-hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. this report presents positron emission tomography/computed tomography (pet/ct)imaging with 2-deoxy-2-18f-fluoro-d-glucose (18f-fdg) in 3 cases of non-hodgkin lymphoma with nerve infiltration, including one newly d...

Different mechanisms such as cell migration, proliferation, branching, anastomosis, and lumen formation occur during the angiogenesis process. Lumen formation is one of the critical mechanisms which is not only necessary for the functional plexus but also for continuing of angiogenesis process. Although multiple studies investigated this mechanism during the angiogenesis process in both in vivo...

Noradrenergic Mediation of Experimental Cerebrovascular Spasm • Catecholamine fluorescent techniques demonstrate an abundant noradrenergic periarterial nerve plexus in the adventitia of the major intracranial vessels. After repeated spasm of these vessels, a marked reduction to complete absence of catecholamine fluorescence is noted. Seemingly, an exhaustion of noradrenalin stores from the nerv...
