Surgical treatment of an aneurysm of the aberrant right subclavian artery involving an aortic arch aneurysm and coronary artery disease. (1/77)
A 55-year-old man presented with clinical signs of an aortic arch aneurysm. Angiography, MRI and CT demonstrated an aortic arch aneurysm and an aneurysm of the aberrant right subclavian artery. Coronary angiography revealed 95% stenosis in the right coronary artery. Right common carotid artery-right subclavian artery bypass, arch graft replacement and coronary artery bypass grafting were performed successfully. The use of internal shunt tube, hypothermic circulatory arrest and selective cerebral perfusion were useful methods in prevention of cerebral ischemia during surgical reconstruction of the aortic arch. To our knowledge, this is the first report in the literature of a successfully managed case with an aneurysm of an aberrant right subclavian artery involving an aortic arch aneurysm and coronary artery disease. (+info)Pharyngolaryngeal morbidity with the laryngeal mask airway in spontaneously breathing patients: does size matter? (2/77)
BACKGROUND: Currently, the manufacturer of the laryngeal mask airway (LMA; Laryngeal Mask Company, Ltd., Northfield End, Henley on Thames, Oxon, United Kingdom) recommends using as large a mask size as possible. The aim of this study was to compare the incidence of pharyngolaryngeal morbidity after the use of a large (size 5 in males and size 4 in females) or small (size 4 in males and size 3 in females) LMA in spontaneously breathing patients. METHODS: A total of 258 male and female patients were randomly assigned to insertion of a large or small LMA while breathing spontaneously during general anesthesia. After insertion of the LMA, a "just-seal" cuff pressure was obtained, and intracuff pressure was measured at 10-min intervals until just before removal of the LMA. The 2- and 24-h incidence of postoperative sore throat, pain, hoarseness, dysphagia, and nausea and vomiting was assessed. Complications after LMA removal, including body movement, coughing, retching, regurgitation, vomiting, biting on the LMA, bronchospasm, laryngospasm, or the presence of blood on the LMA, were recorded. RESULTS: The use of a large LMA was associated with a higher incidence of sore throat in both sexes (20% vs. 7% in men, 21% vs. 5% in women; P < 0.05) and a higher incidence of hoarseness in male patients at 2 h postoperatively (21% vs. 9%, P < 0.05). There was a higher incidence of sore throat in male patients at 24 h postoperatively with the use of a large LMA (26% vs. 12%, P < 0.05). There was no difference in the incidence of complications of LMA removal orother pharyngolaryngeal morbidity, such as difficulty swallowing, drinking, and eating, or nausea and vomiting, between male or female groups at any time period with the use of a large LMA. CONCLUSIONS: Selection of a small laryngeal mask airway (size 4) in spontaneously breathing male patients may be more appropriate to limit the occurrence of sore throat on the first postoperative day. All patients had a fourfold increased risk of developing sore throat when a large LMA was used. (+info)Systematic review of clinical effectiveness of pressurised metered dose inhalers versus other hand held inhaler devices for delivering corticosteroids in asthma. (3/77)
OBJECTIVE: To determine the clinical effectiveness of pressurised metered dose inhalers (with or without spacer) compared with other hand held inhaler devices for the delivery of corticosteroids in stable asthma. DESIGN: Systematic review of randomised controlled trials. DATA SOURCES: Cochrane Airways Group trials database (Medline, Embase, Cochrane controlled clinical trials register, and hand searching of 18 relevant journals), pharmaceutical companies, and bibliographies of included trials. TRIALS: All trials in children or adults with stable asthma that compared a pressurised metered dose inhaler with any other hand held inhaler device delivering the same inhaled corticosteroid. RESULTS: 24 randomised controlled trials were included. Significant differences were found for forced expiratory volume in one second, morning peak expiratory flow rate, and use of drugs for additional relief with dry powder inhalers. However, either these were within clinically equivalent limits or the differences were not apparent once baseline characteristics had been taken into account. No significant differences were found between pressurised metered dose inhalers and any other hand held inhaler device for the following outcomes: lung function, symptoms, bronchial hyper-reactivity, systemic bioavailability, and use of additional relief bronchodilators. CONCLUSIONS: No evidence was found that alternative inhaler devices (dry powder inhalers, breath actuated pressurised metered dose inhalers, or hydrofluoroalkane pressurised metered dose inhalers) are more effective than the pressurised metered dose inhalers for delivery of inhaled corticosteroids. Pressurised metered dose inhalers remain the most cost effective first line delivery devices. (+info)Collapse, hoarseness of the voice and swelling and bruising of the neck: an unusual presentation of thoracic aortic dissection. (4/77)
A 66 year old woman presented to the accident and emergency department with history of collapse, hoarseness of the voice, and swelling and bruising of the neck. The diagnosis was not initially obvious because of the absence of chest pain. The findings on the radiograph of the soft tissue of the neck and chest radiograph suggested the need for computed tomography of the neck and chest. This confirmed the cervical haematoma and typical signs of aortic dissection. This unusual presentation of thoracic aortic dissection is discussed below. (+info)A technique for the prevention of hoarseness during surgery for distal aortic arch aneurysm. (5/77)
Hoarseness occurs frequently after surgery to repair distal aortic arch aneurysms when using only a median sternotomy approach. We describe a useful technique which protects the left recurrent laryngeal nerve during this procedure and reduces the incidence of postoperative hoarseness. (+info)Ocular and respiratory symptoms attributable to inactivated split influenza vaccine: evidence from a controlled trial involving adults. (6/77)
In 2000, an influenza vaccine was associated with unusual ocular and respiratory symptoms (known as "oculorespiratory syndrome" [ORS]) that possibly were due to numerous microaggregates of unsplit viruses present in the product. We assessed the potential for an improved vaccine formulation (for use in 2001-2002) to cause ORS and other symptoms in adults, using a double-blind, randomized, crossover study design. Symptoms were ascertained 24 h after 622 doses of vaccine and 626 doses of saline placebo were injected. The risk of ORS was 6.3% after vaccine injection and 3.4% after placebo injection, which yielded a significant vaccine-attributable risk of 2.9% (95% confidence interval, 0.6-5.2). ORS symptoms were mild. Significant differences in risk after injection of vaccine versus placebo existed for ocular soreness and/or itching (2.4%), coughing (1.6%), and hoarseness (1.2%). Vaccine-attributable general symptoms were infrequent. We conclude that certain mild oculorespiratory symptoms were triggered by an influenza vaccine that was otherwise minimally reactogenic and, hence, that such symptoms might be associated with influenza vaccines in general. (+info)Sore throat and hoarseness after total intravenous anaesthesia. (7/77)
BACKGROUND: Sore throat and hoarseness are common complications, but these have not been studied after total i.v. anaesthesia. METHODS: We prospectively studied 418 surgical patients, aged 15-92 yr, after total i.v. anaesthesia with propofol, fentanyl and ketamine to assess possible factors associated with sore throat and hoarseness. RESULT: We found sore throat in 50% and hoarseness in 55% of patients immediately after surgery. This decreased to 25% for sore throat and 24% for hoarseness on the day after surgery. Both sore throat and hoarseness were more common in females and when lidocaine spray had been used. Cricoid pressure during laryngoscopy was inversely associated with the risk of sore throat. CONCLUSION: Knowledge of these factors may reduce postoperative throat complications, and improve patient satisfaction. (+info)Stereotactic radiosurgery for recurrent pleomorphic adenoma invading the skull base--case report--. (8/77)
A 38-year-old man presented with a recurrent pleomorphic adenoma in the parapharyngeal space invading the skull base 19 years after the first operation for a parotid gland tumor. Stereotactic radiotherapy was performed to control the tumor growth using a marginal dose of 8 Gy and maximum dose of 18 Gy with care taken to minimize the dose to nearby structures. The symptoms were reduced within a few months. Magnetic resonance imaging over 5 years showed that the tumor was controlled with no regrowth. Stereotactic radiotherapy is a therapeutic option for the treatment of pleomorphic adenomas. (+info)1. Raspy or strained voice

Recurrent laryngeal nerve injuries refer to damage or trauma to the recurrent laryngeal nerve, which is a branch of the vagus nerve that supplies motor and sensory functions to the larynx (voice box) and other structures in the neck and throat. These injuries can occur due to various causes such as surgery, trauma, or degenerative conditions.
Types of Recurrent Laryngeal Nerve Injuries:
There are several types of recurrent laryngeal nerve injuries, including:
1. Traumatic injury: This type of injury occurs due to direct blows or penetrating wounds to the neck or throat.
2. Ischemic injury: This type of injury occurs due to reduced blood flow to the nerve, often due to atherosclerosis (narrowing of the blood vessels) or other conditions that affect blood flow.
3. Neuritis: This type of injury occurs due to inflammation of the nerve, often due to viral infections such as herpes zoster (shingles).
4. Tumors: Benign or malignant tumors in the neck or throat can compress or damage the recurrent laryngeal nerve.
5. Surgical injury: Recurrent laryngeal nerve injuries can occur during surgical procedures such as thyroid or parathyroid surgery, or laryngotomy (surgery on the voice box).
Symptoms of Recurrent Laryngeal Nerve Injuries:
The symptoms of recurrent laryngeal nerve injuries can vary depending on the severity and location of the injury. Common symptoms include:
1. Hoarseness or weakness of the voice
2. Difficulty swallowing (dysphagia)
3. Pain in the neck, throat, or ear
4. Numbness or tingling sensations in the neck or face
5. Weakness or paralysis of the vocal cords
6. Inability to speak or vocalize
7. Breathing difficulties
Diagnosis and Treatment of Recurrent Laryngeal Nerve Injuries:
To diagnose a recurrent laryngeal nerve injury, a thorough medical history and physical examination are essential. Imaging studies such as MRI or CT scans may also be ordered to confirm the presence and extent of the injury. Electromyography (EMG) and nerve conduction studies (NCS) may also be performed to assess the function of the nerve.
Treatment of recurrent laryngeal nerve injuries depends on the underlying cause and severity of the injury. Some common treatment options include:
1. Supportive care: Patients with mild symptoms may require only supportive care, such as voice therapy or speech therapy to improve communication.
2. Medications: Anti-inflammatory medications or steroids may be prescribed to reduce swelling and inflammation.

LPR can lead to a range of symptoms, including:
* Hoarseness or a raspy voice
* Chronic cough
* Trouble swallowing
* Throat clearing
* Regurgitation of food
* Difficulty breathing
The exact cause of LPR is not known, but it is thought to be related to a weakening of the lower esophageal sphincter (LES), which allows stomach acid and other digestive juices to flow back up into the throat. Factors that can contribute to the development of LPR include:
* Obesity
* Pregnancy
* Smoking
* Alcohol consumption
* Certain medications
* Eating close to bedtime
LPR is typically diagnosed through a combination of endoscopy, laryngoscopy, and pH testing. Treatment options for LPR include:
