Two cases of combined tracheal and oesophageal stenting for carcinoma of the upper oesophagus invading the tracheo-bronchial tree are described. Case 1 describes the complication of respiratory distress following insertion of a high oesophageal stent. This caused severe stridor which required tracheal stenting. In case 2 prophylactic stenting of the airway prior to oesophageal stenting was performed as a staging CT demonstrated severe compromise of the distal trachea/bronchus in a patient who was experiencing both dysphagia and dyspnoea. In both cases the respiratory and dyspnoeic symptoms were relieved. These cases illustrate the effective use of tracheal/bronchial and oesophageal metal stents in palliating patients with combined respiratory and dysphagic symptoms secondary to oesophageal malignancy. When treating high oesophageal tumours tracheal compromise should be considered and prophylactic stenting of the airway prior to oesophageal stenting performed to avoid further airway compromise when the oesophageal stent expands.

Crack cocaine is commonly smoked in a pipe with a metallic filter made from a steel wool scouring pad. We report an unusual complication of smoking crack cocaine: the aspiration and ingestion of a Brillo pad filter. A 34-year-old female presented 7 h after drinking beer and smoking crack. She was concerned that she might have inhaled the "screen" from her crack pipe, a piece of Brillo pad the size of her fingertip. She complained of "burning" in her throat, a foreign body sensation, and change in her voice, but no dyspnea, dysphagia, or abdominal pain. On physical examination, she was afebrile with a pulse of 105 beats/min and respiratory rate of 24 breaths/min. She was tearful and spoke in a whisper. There were no visible oropharyngeal burns and the lungs were clear to auscultation, but she had intermittent inspiratory stridor. The O2 saturation was 96%, and the ethanol concentration was 100 mg/dl. No foreign body or burn was seen on indirect laryngoscopy. A lateral neck x-ray study showed a normal epiglottis and no foreign body. Chest x-ray studies were unremarkable. Fiberoptic laryngoscopy showed left posterior arytenoid edema and swelling. An abdominal x-ray study revealed a foreign body in the right lower quadrant consistent with the Brillo pad filter. The next morning, the patient was asymptomatic and was discharged, recovering without sequellae. While crack pipe screen aspiration is a rarely reported event, physicians should be aware of the potential for foreign body aspiration and ingestion by this mechanism.

Historical, clinical and experimental data were collected from 9 horses homozygous for HYPP (H/H). All showed episodes of respiratory stertor, described as a rattling or honking sound, usually within the first week post partum. Five horses had one or more episodes of dysphagia, in 3 horses this was accompanied by drooling and in 3 by weight loss. In comparison, only one of 35 contemporaneous half siblings (of which approximately half would be expected to be of the H/N genotype and half N/N) was observed to have respiratory stertor prior to weaning and none had problems with dysphagia. One mature homozygous stallion was infertile secondary to urospermia. Six homozygous horses died or were subjected to euthanasia; 4 age less than a year, one age 20 months and one age 5 years. The remaining 3 cases were still alive at the end of the study. A comparison of homozygous and heterozygous horses using standardised potassium chloride challenge testing indicated that during attacks homozygotes showed significantly more frequent signs of drooling, prolapse of the third eyelid, respiratory stridor and weakness than heterozygous horses. Homozygotes also had significantly more total abnormalities (including myotonic discharges, high frequency repetitive discharges, and spontaneous activity) on electromyographic examination than heterozygotes. These data imply that HYPP is inherited as a codominant genetic defect, because the homozygotes showed more severe clinical signs of disease than heterozygotes. Homozygous foals would be expected to be produced in 25% of matings in which both parents are heterozygous. Owners and veterinarians should be aware of the risks of this mating.

Ludwig's angina is a potentially life-threatening, rapidly expanding, diffuse inflammation of the submandibular and sublingual spaces that occurs most often in young adults with dental infections. However, this disorder can develop in children, in whom it can cause serious airway compromise. Symptoms include severe neck pain and swelling, fever, malaise and dysphagia. Stridor suggests an impending airway crisis. Causative bacteria include many gram-negative and anaerobic organisms, streptococci and staphylococci. Initial treatment consists of high doses of penicillin G given intravenously, sometimes in combination with other drugs. Patients usually recover without complications.

A double aortic arch is described in an 8-week-old female Siamese cat. In this case a vascular ring anomaly consistent with a double aortic arch is described in a cat. Stridor and dysphagia were noted in the cat. Radiography showed an esophageal dilation, with constriction at the fifth intercostal space. At necropsy, the esophagus and trachea were constricted at the base of the heart. The cause of the constriction of both the esophagus and trachea was a vascular ring formed by well-developed right and left aortic arches. The ascending aorta divided into two asymmetrical arches. The right aortic arch was larger than the left. The origin of the major arteries from the aortic arches were anomalous.

Upper airway symptoms or dysphagia may be caused by vascular anomalies, forming a ring around the trachea, oesophagus or both. To analyse the clinical presentation, use of various diagnostic techniques, treatment and follow-up we carried out a retrospective study of 38 children who had been diagnosed with a vascular ring between 1981 and 1996. We found 74% of the vascular rings to be symptomatic, with inspiratory stridor and wheezing as the main complaints. The delay between the onset of symptoms and diagnosis of a vascular ring in patients without associated anomalies ranged from 1 to 84 mo. Associated anomalies were found in 53% of cases and 80% of these anomalies consisted of associated cardiovascular malformations. Oesophagography proved to be a valuable diagnostic technique when a vascular ring was suspected. Echocardiography appeared to be of little value for the diagnosis of a vascular ring, but was essential to exclude associated cardiovascular malformations. Although angiography has always been considered to be the gold standard in the determination of the exact anatomy of vascular rings, increasing evidence is available that CT scan or MRI may replace this role. Mortality was related to co-existent tracheal deformities in 5/6 cases. Of the remaining, preoperatively symptomatic patients, relief of symptoms was achieved immediately after surgery in 43% and within 4 y after surgery in 57%. Prolonged and recurrent respiratory complaints or dysphagia in infancy or childhood should alert the paediatrician to the possibility of a vascular ring.

Vascular rings have been well documented to cause respiratory and gastrointestinal symptoms in infants and children. Few reports document symptomatic vascular rings in adults, and most have emphasized dysphagia as the predominant symptom. We present the case of a 36-year-old white male with a double aortic arch and progressive dyspnea on exertion. This led us to review previous reports of vascular rings in adults. Criteria for review consisted of anatomically complete vascular rings of the aortic arch in adults age 18 years or older. We identified 25 prior cases for review and included our recent patient. The most common vascular ring anomalies in our review of adults is double aortic arch (n = 12; 46%) followed by right aortic arch with aberrant left subclavian artery and ligamentum arteriosum (n = 8; 30%). Of 24 patients (66%), 16 were symptomatic. Reported symptoms involving the respiratory tract (n = 10 of 24; 42%) included dyspnea on exertion (n = 5), bronchitis (n = 2), recurrent pneumonia, stridor, and unspecified respiratory ailment (n = 1 each). Dysphagia was less common, occurring in eight patients (33%). Previously proposed mechanisms for respiratory tract symptoms include tracheomalacia, static or dynamic compression of the airways, intravascular volume infusion, and aspiration. We also propose exercise-induced dilatation of the aortic arch and age-dependent changes in thoracic compliance as potential mechanisms of dyspnea.

A 14-year-old girl with focal dermal hypoplasia (Goltz-Gorlin-syndrome) presented with dysphagia, hoarseness, inspiratory stridor, intermittent dry cough and a 10% weight loss. Endoscopy showed that these symptoms were caused by papillomatosis of the hypopharynx and the larynx. The papillomatous masses were resected subtotally by endoscopic laser treatment. Residual papillomas were left in the subglottic space but tracheotomy could be avoided. Complete clinical recovery with adequate weight gain as well as, resolution of dyspnoe and dysphagia resulted after the intervention. Histological examination did not show morphological signs of human papilloma virus as an etiological agent.

We report an unusual presentation of non-Hodgkin's lymphoma of the thyroid which mimicked an acute infective thyroiditis and was associated with acute stridor and dysphagia. The mode of presentation and diagnosis of thyroid lymphoma are discussed and the value of early fine needle aspiration emphasised.

Congenital cardiovascular anomalies are a rare but treatable cause of stridor in the paediatric population. Despite this, we and the authors of other series have found a delay in referral for endoscopic diagnosis. The duration of symptoms prior to endoscopic diagnosis ranged from 6 weeks to 10 years. It has been estimated that up to 3% of the population have congenital anomalies of the aortic arch complex and we feel that many patients currently being diagnosed as having recurrent croup or atypical asthma must be excluded from this group. We had 16 cases of congenital vascular anomalies causing tracheobronchial compression. Fifteen were due to innominate artery compression and one was due to a double aortic arch. Presenting symptoms included stridor (100%), persistent cough (75%), chronic dyspnoea (75%), reflex apnoea (60%), recurring respiratory tract infections (56%) and dysphagia (25%). Direct laryngoscopy and bronchoscopy was diagnostic in all cases and is our investigation of choice. Eleven underwent aortopexy (69%), one had division of the non-dominant aortic arch (6%) and four were managed conservatively (25%). They were followed for up to 9 years post-operatively and 75% had complete resolution of their symptoms. We feel that only a high clinical index of suspicion will enable these potentially fatal anomalies to be diagnosed.
