Objectives. Sjögren's syndrome (SS) may be complicated by some neurological manifestations, generally sensory polyneuropathy. Furthermore, involvement of cranial nerves was described as rare complications of SS. Methods. We reported 2 cases: the first one was a 40-year-old woman who developed neuritis of the left optic nerve as presenting symptom few years before the diagnosis of SS; the second...

Background: Supraclavicular nerve block is a method for upper limb surgery in Anesthesiology. In this method that is common for supraclavicular block, injection anesthesia on the first rib and it has complications such as pneumothorax, phrenic never pulsy, infection, intra spinal injection. In this study injection with a 10 degree cephalic side as compared with the first rib in order to decreas...

OBJECTIVE The study aims to demonstrate the techniques employed in surgery of the brachial plexus that are associated to evidence-based improvement of the functional outcome of these patients. METHOD A retrospective study of one hundred cases of traumatic brachial plexus injuries. Comparison between the postoperative outcomes associated to some different surgical techniques was demonstrated. ...

We tested the hypothesis that exposure to neonatal intermittent hypoxia (n-IH) in rat pups alters central integrative processes following acute and intermittent peripheral chemoreceptor activation in adults. Newborn male rats were exposed to n-IH or normoxia for 10 consecutive days after birth. We then used both awake and anesthetized 3- to 4-mo-old rats to record ventilation, blood pressure, a...

A 19-year-old man sustained a right upper trunk brachial plexopathy from a stab wound and became paralyzed in the right proximal arm. Twelve months later, he underwent microsurgical anastomosis of injured C5 and C6 nerve roots to the more distal C5 nerve root. At 14 months postoperatively, there were involuntary movements of his right biceps and deltoid muscles time-locked to inspiration (see v...

A 26 week gestation infant had an increasingly elevated right hemidiaphragm following drainage of bilateral pleural effusions and failed extubation on numerous occasions. Electric stimulation of the phrenic nerves revealed absent activity on the right, indicating phrenic nerve injury from chest tube drain insertion. Diaphragmatic plication was performed and the infant successfully extubated fou...
