1/55. Video-assisted thoracoscopic esophagomyotomy for achalasia after pulmonary lobectomy.A 52-year-old man developed achalasia and a lung abscess due to aspiration pneumonia. We conducted a right upper lobectomy by thoracotomy for the abscess and, 2 weeks later, video-assisted thoracoscopic myotomy and fundoplication (modified Belsey Mark IV procedure) though the left thorax for achalasia. Three months after surgery, the patient was free of dysphasia and chest pain and had regained his original weight. Esophageal myotomy and fundoplication using video-assisted thoracoscopy appear to be feasible in treating achalasia involving impaired pulmonary function.- - - - - - - - - - ranking = 1keywords = chest, upper, pain (Clic here for more details about this article) |
2/55. metronidazole-associated pancreatitis.OBJECTIVE: To report a case of acute reversible pancreatitis associated with metronidazole-treated aspiration pneumonia. CASE SUMMARY: A 61-year-old white woman requiring coronary artery bypass surgery developed acute pancreatitis following treatment with metronidazole for suspected postsurgical aspiration pneumonia. The patient developed moderate to severe bilateral upper quadrant abdominal pain; laboratory studies revealed elevated amylase and lipase concentrations four days following the initiation of metronidazole therapy. After discontinuation of metronidazole, the patient's abdominal pain subsequently improved, and both amylase and lipase concentrations immediately declined and were within normal limits within one week. DISCUSSION: An acute attack of pancreatitis is characterized by moderate to severe abdominal pain that may radiate to the back, accompanied by increased concentrations of pancreatic enzymes and few morphologic changes in the pancreas. metronidazole is reported as having a probable association with acute pancreatitis, although the mechanism of drug-induced pancreatitis is not known. One speculative mechanism of metronidazole-induced pancreatitis is that, under aerobic conditions, metronidazole may undergo redox cycling and yield hydrogen peroxide, superoxide, and other free radicals. Such redox-active compounds are toxic to pancreatic beta-cells, and oxygen-centered free radicals have been implicated in the induction of pancreatitis. Other suggested mechanisms include immune-mediated inflammatory response, pancreatic duct constriction, and metabolic effects. CONCLUSIONS: Very few cases of metronidazole-associated pancreatitis have been reported, and the long-term sequelae are unknown. However, if metronidazole or any other drug is suspected as the causative agent in pancreatitis, it should be discontinued and rechallenge should be avoided.- - - - - - - - - - ranking = 0.36473474118279keywords = upper, pain (Clic here for more details about this article) |
3/55. The child with persistent cough.Coughing is a healthy reflex. Causes of a cough can vary from minor upper respiratory illnesses to malignancy. When a child's cough continues for weeks, parents worry. Primary care providers must decide when reassessment is needed and if a vigorous workup and referral to a pulmonologist are required. The above discussion should assist these physicians.- - - - - - - - - - ranking = 0.20259013482357keywords = upper (Clic here for more details about this article) |

5/55. hypercapnia related to a faulty adult co-axial breathing circuit.IMPLICATIONS: This report describes the appearance of CO2 on the capnograph during inspiration, which was linked to disconnection of the inner tube of a coaxial circuit extension piece. The increased use of coaxial breathing systems for adults makes inner tubes disconnections an important consideration when the CO2 appears during inspiration.- - - - - - - - - - ranking = 157.19907822148keywords = breathing (Clic here for more details about this article) |
6/55. Dynamic laryngotracheal closure for aspiration: a preliminary report.OBJECTIVES/HYPOTHESIS: An estimated 500,000 patients per year in the united states. are affected by stroke-related dysphagia. Approximately half experience aspiration, which can lead to pneumonia or death. Aspiration may result from many factors, including delayed transport of the bolus, faulty laryngeal elevation, and poor coordination or inappropriate timing of vocal cord closure. Interventions carried out to protect the lungs are usually irreversible, destructive to the upper airway, and rarely prevent the need for enteral tube feeding. STUDY DESIGN: We present a report of the first implantations of a new device in an FDA-approved study to restore dynamic laryngotracheal separation. Two stroke patients needing tracheostomy were selected based on chronic aspiration verified by clinical and radiologic criteria (modified barium swallow [MBS]). methods: The left recurrent laryngeal nerve was exposed and electrically stimulated to verify vocal fold adduction. Huntington Medical research Institute Bipolar Helical electrodes were then implanted around the nerve. The leads were tunneled and linked to a NeuroControl Implantable Receiver-Stimulator placed subcutaneously on the chest wall. Activation of the stimulator was performed through an external transmitter linked by induction. RESULTS: The device was successfully triggered intra- and postoperatively. Serial flexible fiberoptic endoscopies and MBS demonstrate that aspiration is systematically arrested using low levels of electrical stimulation (42 Hz, 48-100 microsec, 1 mA). DISCUSSION: This pioneering work has shown that aspiration can be controlled without airway damage for a wide population of neurologically impaired patients because it appears more physiological than standard therapies. CONCLUSION: Based on the first two patients, paced laryngotracheal separation is clinically effective in controlling aspiration.- - - - - - - - - - ranking = 0.94595179788026keywords = chest, upper (Clic here for more details about this article) |
7/55. Unusual arachnoid cyst of the quadrigeminal cistern in an adult presenting with apneic spells and normal pressure hydrocephalus--case report.A 67-year-old woman was admitted to our clinic with symptoms of normal pressure hydrocephalus, lower cranial nerve pareses, and pyramidal and cerebellar signs associated with respiratory disturbances. Computed tomography (CT) and magnetic resonance imaging revealed a 4.7 x 5.4 cm quadrigeminal arachnoid cyst causing severe compression of the tectum and entire brain stem, aqueduct, and cerebellum, associated with moderate dilation of the third and lateral ventricles. Emergency surgery was undertaken due to sudden loss of consciousness and impaired breathing. The cyst was totally removed by midline suboccipital craniotomy in the prone position. Postoperatively, her symptoms improved except for the ataxia and impaired breathing. She was monitored cautiously for over 15 days. CT at discharge on the 18th postoperative day revealed decreased cyst size to 3.9 x 4.1 cm. Histological examination confirmed the diagnosis of the arachnoid cyst of the quadrigeminal cistern. The patient died of respiratory problems on the 5th day after discharge. Quadrigeminal arachnoid cysts may compress the brain stem and cause severe respiratory disturbances, which can be fatal due to apneic spells. patients should be monitored continuously in the preoperative and postoperative period until the restoration of autonomous ventilation is achieved.- - - - - - - - - - ranking = 62.87963128859keywords = breathing (Clic here for more details about this article) |
8/55. Upper airway abnormalities in canavan disease.OBJECTIVE: To describe upper airway anatomical abnormalities associated with canavan disease. methods: Retrospective case report. RESULTS: physical examination and laryngoscopy demonstrated oropharyngeal narrowing, macroglossia, and bronchial asymmetry in a child with canavan disease. tracheostomy decreased problems with chronic aspiration and obstructive sleep apnea. CONCLUSIONS: Oropharyngeal obstruction and bronchial asymmetry are previously undescribed upper airway abnormalities found in an individual with canavan disease. tracheostomy is an effective method of managing chronic aspiration and obstruction in these patients.- - - - - - - - - - ranking = 0.40518026964715keywords = upper (Clic here for more details about this article) |
9/55. Rocuronium-induced generalized spontaneous movements cause pulmonary aspiration.Rapid-sequence induction with cricoid pressure is a standard procedure for inducing anesthesia in patients with a potentially full stomach. During the induction period, if the patient develops generalized movements of the body, the pressure level of the cricoid may change unexpectedly. As a result, the increase in intragastric pressure may cause gastric regurgitation and consequent pulmonary aspiration. Rocuronium has been widely used as an alternative to succinylcholine during the induction of anesthesia. However, most patients who received rocuronium complained of severe burning pain in their arm during intravenous injection. Even after the administration of the induction agents, rocuronium injection can also cause withdrawal of the hand or other generalized movements of the body. We describe a case of gastric regurgitation with pulmonary aspiration following generalized spontaneous movements associated with rocuronium injection in a girl who received pediatric emergent surgery.- - - - - - - - - - ranking = 0.054048202119738keywords = pain (Clic here for more details about this article) |
10/55. Aspiration of fruit gel snacks.Aspiration of a foreign body is common in children and can cause upper airway obstruction, leading to significant morbidity or mortality. We report 3 cases of aspiration of a popular fruit-flavored gel snack that led to cardiopulmonary arrest and death in 1 case and respiratory failure in 2 other cases. There is increasing concern about the safety of this gel snack and its risk of aspiration, even in older children. Pediatricians should advise parents and children about the dangers of eating this candy during their health maintenance visits.- - - - - - - - - - ranking = 0.20259013482357keywords = upper (Clic here for more details about this article) |
