1/38. myasthenia gravis presenting with dysphagia and postoperative ventilatory failure.We report a case of myasthenia gravis presenting to the department of otolaryngology with acute dysphagia on two separate occasions over a one-year period. diagnosis of myasthenia gravis was made when the patient developed ventilatory failure after his second general anaesthetic for rigid oesophagoscopy. Our patient required emergency transfer to the intensive therapy unit for ventilation. He improved after treatment with corticosteroids, anticholinesterase and immunosuppressive medications. Our case was unusual in that cricopharyngeal spasm causing dysphagia and significant aspiration was demonstrated by a barium swallow and this was completely resolved after treatment of the myasthenia gravis.- - - - - - - - - - ranking = 1keywords = spasm (Clic here for more details about this article) |
2/38. Bilateral contemporaneous posteroventral pallidotomy for the treatment of Parkinson's disease: neuropsychological and neurological side effects. Report of four cases and review of the literature.The authors report the underestimated cognitive, mood, and behavioral complications in patients who have undergone bilateral contemporaneous pallidotomy, as seen in their early experience with functional neurosurgery for Parkinson's disease (PD) that is accompanied by severe motor fluctuations before pallidal stimulation. Four patients, not suffering from dementia, with advanced (Hoehn and Yahr Stages III-IV), medically untreatable PD featuring severe "on-off" fluctuations underwent bilateral contemporaneous posteroventral pallidotomy (PVP). All patients were evaluated according to the Core Assessment Program for Intracerebral Transplantations (CAPIT) protocol without positron emission tomography scans but with additional neuropsychological cognitive, mood, and behavior testing. For the first 3 to 6 months postoperatively, all patients showed a mean improvement of motor scores on the Unified Parkinson's disease Rating Scale (UPDRS), in the best "on" (21%) and worst "off" (40%) UPDRS III motor subscale, a mean 30% improvement in the UPDRS II activities of daily living (ADL) subscore, and 60% on the UPDRS IV complications of treatment subscale. Dyskinesia disappeared almost completely, and the mean daily duration of the off time was reduced by an average of 60%. Despite these good results in the CAPIT scores, one patient experienced a partially regressive corticobulbar syndrome with dysphagia, dysarthria, and increased drooling. No emotional lability was found in this patient, but he did demonstrate severe bilateral postoperative pretarsal blepharospasm (apraxia of eyelid opening), which interfered with walking and which required treatment with high-dose subcutaneous injections of botulinum toxin. No patient showed visual field defects or hemiparesis, but postoperative depression, changes in personality, behavior, and executive functions were seen in two individuals. Postoperative abulia was reported by the family of one patient, who lost his preoperative aggressiveness and drive in terms of ADL, speech, business, family life, and hobbies, and became more sleepy and fatigued. One patient reported postoperative mental automatisms, such as compulsive mental counting, and circular thoughts and reasoning during off phases; postoperative depression was found in two patients. However, none of the patients demonstrated these symptoms during intraoperative microelectrode stimulation. These findings are compatible with previous reports on bilateral pallidal lesions. A progressive lowering of UPDRS subscores was seen after 12 months, consistent with the progression of the disease. Bilateral simultaneous pallidotomy may be followed by emotional, behavioral, and cognitive deficits such as depression, obsessive-compulsive disorders, and loss of psychic autoactivation-abulia, as well as disabling corticobulbar dysfunction and apraxia of eyelid opening, in addition to previously described motor and visual field deficits, which make this surgery undesirable even though significant improvement in motor deficits can be achieved.- - - - - - - - - - ranking = 1keywords = spasm (Clic here for more details about this article) |

4/38. multiple sclerosis and oral care.multiple sclerosis is a complex neurological condition affecting sensory and motor nerve transmission. Its progression and symptoms are unpredictable and vary from person to person as well as over time. Common early symptoms include visual disturbances, facial pain or trigeminal neuralgia and paraesthesia or numbness of feet, legs, hands and arms. These, plus symptoms of spasticity, spasms, tremor, fatigue, depression and progressive disability, impact on the individual's ability to maintain oral health, cope with dental treatment and access dental services. Also, many of the medications used in the symptomatic management of the condition have the potential to cause dry mouth and associated oral disease. There is no cure for multiple sclerosis, and treatment focuses on prevention of disability and maintenance of quality of life. Increasingly a multi-disciplinary team approach is used where the individual, if appropriate his/her carer, and the specialist nurse are key figures. The dental team plays an essential role in ensuring that oral health impacts positively on general health.- - - - - - - - - - ranking = 1keywords = spasm (Clic here for more details about this article) |
5/38. Restoration of peristalsis in the esophagus of a patient diagnosed of achalasia.We report the case of a patient with dysphagia in whom a clinical and manometric follow-up was carried out. We initially observed a motor disorder of the esophageal spasm type. During manometric follow-up a progression to vigorous achalasia was observed. The patient was treated with pneumatic dilation, which obtained a good response to treatment. In manometries performed after treatment we observed a return of peristalsis in the distal esophageal body. Early treatment and short evolution of disease may allow peristalsis to recover in these cases. peristalsis recovery casts new doubts on achalasia etiology.- - - - - - - - - - ranking = 2638.420851208keywords = esophageal spasm, spasm (Clic here for more details about this article) |
6/38. Anti-neuronal nuclear autoantibody type 2: paraneoplastic accompaniments.We identified the IgG autoantibody ANNA-2 ("anti-Ri") in 34 patients in a 12-year period by immunofluorescence screening of sera from approximately 75000 patients with subacute neurological disorders that were suspected to be paraneoplastic. Detailed clinical information was available for 28 patients (10 men, 18 women). Cancer was diagnosed in 24 patients (86%); 21 had histologically proven carcinoma (10 lung, 9 breast, 1 cervical, 1 bladder), and 3 had an intrathoracic imaging abnormality. Cancer anteceded neurological symptoms in 4 of 28 patients. Cancer detection frequency increased with continued surveillance. Neurological disorders, in decreasing frequency, were brainstem syndrome (including opsoclonus, myoclonus, or both), cerebellar syndrome, myelopathy, peripheral neuropathy, cranial neuropathy, movement disorder, encephalopathy, Lambert-Eaton syndrome, and seizures. Four patients had laryngospasm and four had jaw opening dystonia (two with neck dystonia). Nine (32%) were wheelchair-bound 1 month after neurological symptom onset. Most improved neurologically after immunomodulatory or tumor-directed therapy. Accompanying autoantibodies, found in 73% of sera, included ANNA-1, ANNA-3, CRMP-5-IgG, P/Q-type and N-type Ca(2 ) channel antibodies, and muscle-type acetylcholine receptor antibody. Some neurological accompaniments of ANNA-2 may reflect potentially pathogenic humoral or cell-mediated responses to coimmunogenic tumor antigens, for example, Lambert-Eaton syndrome (P/Q-type Ca(2 ) channel antibody) and peripheral neuropathy (ANNA-1 effector T cells).- - - - - - - - - - ranking = 1keywords = spasm (Clic here for more details about this article) |
7/38. nitrazepam-induced cricopharyngeal dysphagia, abnormal esophageal peristalsis and associated bronchospasm: probable cause of nitrazepam-related sudden death.nitrazepam was used in the treatment of resistant myoclonic epilepsy in 38 children. After the occurrence of nitrazepam-associated swallowing incoordination, high-peaked esophageal peristalsis and related bronchospasm in one patient, we initiated a prospective study of esophageal manometry using a station pull-through technique with a pediatric 4-channel continuous perfusing system. Three more patients were found to have delayed cricopharyngeal relaxation and high-peaked esophageal peristaltic waves. The initial patient developed severe respiratory distress and bronchospasm necessitating ventilatory support while on nitrazepam and improved dramatically with subsequent normal manometric study following nitrazepam discontinuation. nitrazepam was reintroduced for its anticonvulsant and cognitive benefits and was tolerated at a reduced dosage. We postulate a central nervous system effect of nitrazepam promoting parasympathetic overactivity or vagotonia which can cause potentially fatal respiratory distress. Care must be exercised in nitrazepam use and esophageal manometry may be helpful in defining patients at greater risk for sudden death.- - - - - - - - - - ranking = 6keywords = spasm (Clic here for more details about this article) |
8/38. Prolonged effect of botulinum toxin injection in the treatment of cricopharyngeal dysphagia: case report and literature review.Cricopharyngeus (CP) muscle spasm can lead to severe dysphagia. Myotomy of the CP muscle was the treatment of choice. Recently, botulinum toxin type A (BtxA) has been used for CP spasm. It usually brings improvement in deglutition but most patients require reinjection in 3-5 months. We report a 35-year-old man who had an arteriovenous malformation hemorrhage in the brain stem resulting in CP spasm and consequently severe dysphagia. He received BtxA injection and deglutition and nutrition remained good one year after treatment. A literature review analyzing 28 patients and our patient showed negative correlations between age and BtxA dose and between age and duration. Efficacy was positively correlated with duration and BtxA dose was positively correlated with pretreatment severity. In conclusion, physicians would use higher doses on patients with more severe cases but use lower doses on older patients. Those who obtained better post-treatment results would enjoy longer effective duration. Thus, the effective duration of the BtxA is multifactorial.- - - - - - - - - - ranking = 3keywords = spasm (Clic here for more details about this article) |
9/38. High-resolution manometry predicts the success of oesophageal bolus transport and identifies clinically important abnormalities not detected by conventional manometry.BACKGROUND AND AIMS: High-resolution manometry (HRM) is a recent development in oesophageal measurement; its value in the clinical setting remains a matter of controversy. (i) We compared the accuracy with which bolus transport could be predicted from conventional manometry and HRM. (ii) The clinical value of HRM was assessed in a series of patients with endoscopy-negative dysphagia in whom conventional investigations had been non-diagnostic. METHOD: (i) Control subjects and patients with endoscopy-negative dysphagia underwent concurrent HRM and video-fluoroscopy. Ninety-five records were reviewed using HRM with spatiotemporal plot and conventional line plots of the pressure data derived from the same recording. (ii) The HRM and notes of patients with endoscopy-negative dysphagia and abnormal bolus transport were analysed to identify additional information provided by the new technique. RESULTS: (i) Receiver operating characteristic analysis demonstrated that HRM predicts the presence of abnormal bolus transport more accurately than conventional manometry. (ii) HRM identified clinically important motor dysfunction not detected by manometry and radiography. These included localized disturbances of peristalsis and abnormal movement of the lower oesophageal sphincter during oesophageal spasm. CONCLUSION: The HRM predicts bolus movement more accurately than conventional manometry and identifies clinically relevant oesophageal dysfunction not detected by other investigations including conventional manometry.- - - - - - - - - - ranking = 2638.420851208keywords = esophageal spasm, spasm (Clic here for more details about this article) |
10/38. Dysphagia as a side effect of botulinum toxin injection.Dysphagia is a known adverse effect of botulinum toxin injection into the cervical region for dystonia. We present an unusual case of dysphagia arising from injection into the orbicularis oculi muscle, which has hitherto not been described. We postulate that her dysphagia was caused by distant side effects of botulinum toxin due to repeated injections. We recommend that clinicians should restrict the frequency of injections to as few life-time doses of the toxin as possible for adequate management of spasm. The practice of re-injecting patients routinely every three months, or at the first return of mild spasms should be discouraged.- - - - - - - - - - ranking = 2keywords = spasm (Clic here for more details about this article) |
