A Novel Untethering and Duraplasty Technique for Postsurgical Tethered Spinal Cord.

Progressive post-traumatic postsurgical myelopathy (PPPM) is a known entity that can occur months to years after the initial insult. Symptomatic patients can become myelopathic and have rapid and progressive neurological decline. Surgical correction of PPPM usually involves intradural exploration and lysis of adhesions that carries the risk of further injury to the spinal cord.

Transplantation of human neural progenitor cells secreting GDNF into the spinal cord of patients with ALS: a phase 1/2a trial.

Amyotrophic lateral sclerosis (ALS) involves progressive motor neuron loss, leading to paralysis and death typically within 3-5 years of diagnosis. Dysfunctional astrocytes may contribute to disease and glial cell line-derived neurotrophic factor (GDNF) can be protective. Here we show that human neural progenitor cells transduced with GDNF (CNS10-NPC-GDNF) differentiated to astrocytes protected spinal motor neurons and were safe in animal models.

Severe Chin-on-Chest Cervical Spine Deformity in the Setting of Stiff-Person Syndrome: A Case Report.

Case: Stiff-person syndrome (SPS) presents with progressive muscle rigidity, postural instability, and periodic debilitating spasms. Reports of axial hyperextension exist, but kyphotic deformities have not been described. We surgically treated a patient with debilitating SPS and severe cervicothoracic hyperkyphosis with posterior spinal fusion and instrumentation.

Rubinstein-Taybi Syndrome Associated with Pituitary Macroadenoma: A Case Report.

Rubinstein-Taybi Syndrome (RSTS) is an autosomal dominant disorder that is classically characterized by prenatal and postnatal growth restriction, microcephaly, dysmorphic craniofacial features, broad thumbs and toes, and intellectual disability. We describe the first reported case of a pituitary macroadenoma associated with RSTS. A 39-year-old Caucasian female with a past medical history of RSTS diagnosed at age two was found to have a gadolinium-enhancing pituitary mass on magnetic resonance imaging (MRI) of the brain three years ago during workup for migraine-like headaches.

Comparison of three video laryngoscopy devices to direct laryngoscopy for intubating obese patients: a randomized controlled trial.

Study Objective: To compare three different video laryngoscope devices (VL) to standard direct laryngoscopy (DL) for tracheal intubation of obese patients undergoing bariatric surgery.

Hypothesis: VL (vs DL) would reduce the time required to achieve successful tracheal intubation and improve the glottic view.

Design: Prospective, randomized and controlled.

Comparison of the C-MAC video laryngoscope to a flexible fiberoptic scope for intubation with cervical spine immobilization.

Study Objective: To compare the C-MAC video laryngoscope to the standard flexible fiberoptic scope (FFS) with an eye piece (but without a camera or a video screen) for intubation of patients undergoing cervical spine surgery with manual inline stabilization. The primary end point was the time to achieve successful tracheal intubation. Secondary end points included glottic view at intubation and number of intubation attempts.

Use of a disposable acupressure device as part of a multimodal antiemetic strategy for reducing postoperative nausea and vomiting.

Background: There is still controversy regarding the optimal strategy for managing postoperative nausea and vomiting (PONV) in high-risk surgical populations. Although acustimulation at the P6 acupoint has been demonstrated to be effective in preventing PONV, the effect of this nonpharmacologic therapy on the patient's recovery with respect to resumption of normal activities of daily living has not been previously assessed when it is used as part of a multimodal antiemetic regimen. Therefore, we designed this randomized, sham-controlled, and double-blind study to assess the efficacy of a disposable acupressure device (Pressure Right®; Pressure Point Inc.

The effects of oral ibuprofen and celecoxib in preventing pain, improving recovery outcomes and patient satisfaction after ambulatory surgery.

Background: Nonsteroidal antiinflammatory drugs have become increasingly popular as part of multimodal analgesic regimens for pain management in the ambulatory setting. We designed this randomized, double-blind, placebo-controlled study to evaluate the effect of postoperative administration of either a nonselective nonsteroidal antiinflammatory drug (ibuprofen) or the cyclooxygenase-2 selective inhibitor (celecoxib when administered as part of a multimodal analgesic regimen) on the severity of pain, the need for rescue analgesics, and clinically relevant patient outcomes after ambulatory surgery. The primary end point was the time to resumption of normal activities of daily living.

Nonopioid anesthesia for awake craniotomy: a case report.

Awake craniotomy is becoming more popular as a neurosurgical technique that allows for increased tumor resection and decreased postoperative neurologic morbidity. This technique, however, presents many challenges to both the neurosurgeon and anesthetist. An ASA class II, 37-year-old man with recurrent oligodendroglioma presented for repeated craniotomy.

Desflurane versus sevoflurane for maintenance of outpatient anesthesia: the effect on early versus late recovery and perioperative coughing.

Background: There is controversy regarding the relative perioperative benefits of desflurane versus sevoflurane when used for maintenance of anesthesia in the ambulatory setting. Although studies have consistently demonstrated a faster emergence with desflurane (versus sevoflurane), the impact of this difference on the later recovery end points has not been definitively established. Furthermore, the effect of desflurane (versus sevoflurane) on the incidence of coughing is also controversial.

The use of oral granisetron versus intravenous ondansetron for antiemetic prophylaxis in patients undergoing laparoscopic surgery: the effect on emetic symptoms and quality of recovery.

Based on comparative studies in patients receiving emetogenic chemotherapy, it has been suggested that granisetron would be more effective than ondansetron for the prevention of postdischarge nausea and vomiting (PDNV). However, there have been no direct comparisons of these two popular 5-HT3 antagonists with respect to PDNV and quality of recovery. We designed this randomized, double-blind study to compare the antiemetic efficacy of oral granisetron (1 mg) to a standard IV dose of ondansetron (4 mg) when administered for antiemetic prophylaxis as part of a multimodal regimen in a laparoscopic surgical population.

A comparison of state and response entropy versus bispectral index values during the perioperative period.

Cerebral monitoring indices are associated with a large degree of inter-patient variability and electrical signal interference during surgery. We designed this clinical study to test the hypothesis that use of the spectral entropy (Entropy) module is associated with less frequent intraoperative interference with the displayed indices than the bispectral index (BIS) monitor when used during general anesthesia with propofol and desflurane. Thirty consenting patients scheduled for major laparoscopic surgery procedures were enrolled in this prospective study.

Perioperative rofecoxib improves early recovery after outpatient herniorrhaphy.

Unlabelled: Non-opioid analgesics have become increasingly popular as part of a multimodal regimen for pain management in the ambulatory setting. We designed this randomized, double-blind, placebo-controlled study to evaluate the effect of perioperative administration of the cyclooxygenase-2 inhibitor rofecoxib on patient outcome after inguinal herniorrhaphy procedures. Sixty consenting outpatients undergoing elective hernia repair surgery were randomly assigned to one of two treatment groups: control (vitamin C, 500 mg) or rofecoxib (rofecoxib, 50 mg).

The effect of intraoperative use of esmolol and nicardipine on recovery after ambulatory surgery.

Unlabelled: There is controversy regarding the optimal technique for maintaining hemodynamic stability during anesthesia. We designed this prospective, randomized, double-blinded study to test the hypothesis that the technique used for maintaining hemodynamic stability during general anesthesia can influence recovery after ambulatory surgery. Forty-five healthy consenting women undergoing gynecologic laparoscopy procedures were randomly assigned to 1 of 3 treatment groups: Group 1 (control, n = 15) received normal saline 5 mL and 1 mL, followed by a saline infusion at a rate of 0.

Antiemetic prophylaxis for office-based surgery: are the 5-HT3 receptor antagonists beneficial?

Background: Office-based surgery has become increasingly popular because of its cost-saving potential. However, the occurrence of postoperative nausea and vomiting (PONV) can delay patient discharge. Prophylaxis using a combination of antiemetic drugs has been suggested as an effective strategy for minimizing PONV.

Effect of maintenance bolus on the recovery profile of a short-acting nondepolarizing muscle relaxant.

Study Objective: To evaluate the effect of different maintenance boluses of a short-acting nondepolarizing neuromuscular blocking drug on its spontaneous recovery profile during anesthesia.

Design: Prospective, randomized, double-blind, dose-ranging study.

Setting: University-based medical center.

Effect of parecoxib, a novel intravenous cyclooxygenase type-2 inhibitor, on the postoperative opioid requirement and quality of pain control.

Background: The analgesic efficacy and side effect profile of intravenous parecoxib, a novel cyclooxygenase type-2 (COX-2) inhibitor, was assessed in a double-blinded, placebo-controlled study involving patients undergoing major gynecologic surgical procedures.

Methods: After Institutional Review Board approval, 60 consenting women, American Society of Anesthesiologists (ASA) physical status I-III, undergoing lower abdominal surgery with a standardized general anesthetic technique were randomly assigned to receive one of three study medications: group 1 (control) received normal saline; group 2 received intravenous parecoxib, 20 mg; and group 3 received intravenous parecoxib, 40 mg. The initial dose of study medication was administered when the patient first requested pain medication after surgery.
