Negative pressure pulmonary edema after general anesthesia using the i-gel.

Negative pressure pulmonary edema (NPPE) is a rare complication that occurs mainly after tracheal extubation. We report a case of postoperative NPPE associated with the use of the i-gel. A 28-year-old woman was scheduled for an emergency right axillary sentinel lymph node excision.

Effect on music therapy on quality of recovery and postoperative pain after gynecological laparoscopy.

Background: Music therapy is safe, inexpensive, simple, and has relaxing properties for mental and physical capacities, as well as few side effects. Moreover, it improves patient satisfaction and reduces postoperative pain. Thus, we intended to evaluate the effect of music intervention on the quality of comprehensive recovery using quality of recovery 40 (QoR-40) survey in patients undergoing gynecological laparoscopic surgery.

Laryngeal mass induced severe ventilatory impairment during induction of anesthesia.

A 77-year-old man with laryngeal cancer was scheduled for total laryngectomy and lymph node dissection surgery under general anesthesia. The patient did not present with airway obstruction signs, including dyspnea or wheezing sounds during spontaneous respiration, and the laryngeal opening could be easily identified on the fiberoptic bronchoscope examination preoperatively. Due to his poor cognition and cooperation, we decided not to try awake fiberoptic intubation.

Longitudinal transitions in patterns of post-traumatic stress disorder symptoms and psychological distress among South Korean adults with traumatic experiences.

This study aimed to investigate transitions in patterns of post-traumatic stress disorder (PTSD) symptoms and psychological distress among South Koreans with traumatic experiences. This study consists of two parts: In Part 1 the time since trauma ranged between 0 and 41 years, while in Part 2 participants experienced at least one traumatic event within the previous three years. We identified subgroups and transitions between classes over a one-year period using latent profile analysis and latent transition analysis.

Bilateral vocal cord paralysis during emergence from general anesthesia in a patient with Parkinson's disease.

Parkinson's disease (PD) is a neurodegenerative disorder that affects the extrapyramidal system, and respiratory dysfunction has also been noted in patients with PD. However, acute upper airway obstruction due to bilateral vocal cord paralysis is a very rare finding in PD. Here, we describe a rare life-threatening respiratory failure caused by bilateral vocal cord paralysis in an elderly woman with PD during emergence from general anesthesia.

Successful difficult airway management using GlideScope video laryngoscope in a child with Cornelia de Lange Syndrome.

Management of airway in a child with Cornelia de Lange Syndrome (CdLS) should be given due consideration because most of them have the problems related to difficult airway. The GlideScope video laryngoscope can be attempted during routine intubation, however it is mostly used in case of difficulty. With adequate preoperative airway assessment, we used the pediatric video laryngoscope as useful alternative airway device in a child with CdLS and orotracheal intubation proceeded uneventfully.

Effects of Intraneural Injection of Dexmedetomidine in Combination With Ropivacaine in Rat Sciatic Nerve Block.

Background And Objectives: Dexmedetomidine is known to have neural protection effect via attenuation of inflammatory responses induced by local anesthetics. We investigated whether intraneural dexmedetomidine is effective for attenuating or preventing neural injury resulting from inadvertent intraneural injection of local anesthetic.

Methods: Rats were randomly divided, and left sciatic nerve was surgically exposed.

Successful removal of an intractable mucoid impaction in the bronchus using a Fogarty catheter with flexible bronchoscopy.

Rigid bronchoscopy is commonly used as the standard method to diagnosis and remove obstructive material from the tracheobronchial tree. However, a rigid bronchoscope has limitations when removing a foreign body with surface properties that make it difficult to grasp. We experienced a case that involved the removal of a mucoid impaction, which was accompanied by a near-total unilateral lung collapse, using a Fogarty catheter with flexible bronchoscopy.

Hypoxic hepatitis during the perioperative period in patients with severe pulmonary disease and cor pulmonale.

Hypoxic hepatitis (HH) is characterized by marked and transient elevations in liver enzyme levels in the absence of other potential causes of liver injury. Although rare, it can occur in the presence of hemodynamic instability and hypoxemia in patients with cor pulmonale. We report two cases of perioperative HH in patients with severe pulmonary disease and cor pulmonale.

The shape of middle cerebral artery and plaque location: high-resolution MRI finding.

Background: The location of plaque may be associated with the vascular geometry.

Aim: We aimed to examine the relationship between the geometry of middle cerebral artery and the plaque location detected by high-resolution magnetic resonance imaging.

Methods: Among patients with a single subcortical infarction without a significant middle cerebral artery stenosis on magnetic resonance angiography, those with a plaque detected from high-resolution magnetic resonance imaging were prospectively enrolled.

Isolated MCA disease in patients without significant atherosclerotic risk factors: a high-resolution magnetic resonance imaging study.

Background And Purpose: Diagnosis of intracranial artery atherosclerosis remains often uncertain. The high-resolution magnetic resonance imaging (HR-MRI) enables vessel wall assessment for more precise diagnoses. The aim of the present study was to investigate the etiologies of middle cerebral artery steno-occlusive disease in young adult patients with few atherosclerotic risk factors using HR-MRI.

Diagnostic and prognostic value of multimodal MRI in transient ischemic attack.

Background: The clinical diagnosis of transient ischemic attack is highly subjective, and the risk prediction after transient ischemic attack using the clinical parameters still remains unsatisfactory.

Aims: We aimed to investigate the diagnostic and prognostic value of multimodal magnetic resonance imaging in transient ischemic attack patients.

Methods: We prospectively performed diffusion-weighted imaging, perfusion-weighted imaging, and intracranial and extracranial magnetic resonance angiogram within 72 h of symptom onset in 162 transient ischemic attack patients defined by the classical time-based definition.

Endovascular therapy of bronchial artery aneurysm: five cases with six aneurysms.

The objective of this study was to investigate the effect of transcatheter arterial embolization (TAE) with N-butyl-2-cyanoacrylate (NBCA)-Lipiodol mixture in patients with bronchial artery aneurysm (BAA). From January 2005 to January 2010, five patients presenting hemoptysis with six BAAs were treated with NBCA-Lipiodol mixture, including intra-aneurysm embolization (IAE) in one patient. Adjuvant embolization with spherical polyvinyl alcohol (PVA) embolic microparticles or NBCA was first performed to embolize the distal engorged bronchiectatic arteries.

Comparison between MRI screening and CT-plus-MRI screening for thrombolysis within 3 h of ischemic stroke.

Background And Purpose: Although MRI may provide much information on brain pathology to aid in patient selection for thrombolysis, the concern remains that MRI screening may increase time-to-treatment. We hypothesized that CT-plus-MRI screening might be a valuable time-efficient alternative for selection of patients requiring thrombolysis.

Methods: We reviewed acute stroke patients who received intravenous tissue plasminogen activator (tPA) (with or without intra-arterial urokinase) initiated within 3 h of stroke between March 2004 and March 2007.

Polyphenol (-)-epigallocatechin gallate during ischemia limits infarct size via mitochondrial K(ATP) channel activation in isolated rat hearts.

Polyphenol (-)-epigallocatechin gallate (EGCG), the most abundant catechin of green tea, appears to attenuate myocardial ischemia/reperfusion injury. We investigated the involvement of ATP-sensitive potassium (K(ATP)) channels in EGCG-induced cardioprotection. Isolated rat hearts were subjected to 30 min of regional ischemia and 2 hr of reperfusion.

Focal fluid-attenuated inversion recovery hyperintensity within acute diffusion-weighted imaging lesions is associated with symptomatic intracerebral hemorrhage after thrombolysis.

Background And Purpose: We investigated whether focal hyperintensity on fluid-attenuated inversion recovery image within acute infarcts is associated with symptomatic intracerebral hemorrhage (SICH) after thrombolysis.

Methods: Patients with acute ischemic stroke who underwent MRI screening before thrombolysis were enrolled. The presence of focal fluid-attenuated inversion recovery hyperintensity within acute infarcts did not preclude thrombolysis.

Primary malignant melanoma of the cervical spinal nerve root.

The authors report on a case of primary malignant melanoma of the 7th cervical spinal nerve root in a 45-year-old woman. Neuro-radiological features of this extra-dural mass were suggestive of a nerve sheath tumor. The lesion underwent total gross resection through the anterolateral approach.
