1/39. Aspirated foreign bodies in the tracheobronchial tree: report of 250 cases.

    During the last 14 years, 250 patients with aspirated foreign bodies in the tracheobronchial tree were admitted to kuwait Chest Diseases Hospital. Ninety-six per cent of the cases were under 10 years of age and 38% gave a clear history of foreign body inhalation. The rest were diagnosed either clinically, from the chest radiograph findings or because of unexplained pulmonary symptoms. In 247 cases, bronchoscopy under general anaesthesia was successful in removing the foreign bodies. In only three cases was bronchotomy needed. Seventy per cent of the foreign bodies were melon seeds. asphyxia and cardiac arrest occurred in four cases during bronchoscopy but the patients were successfully resuscitated. In 10 cases a tracheostomy was done before bronchoscopy and the removal of the foreign body, while in five it was needed after bronchoscopy. Fifteen patients developed late complications such as recurrent pneumonia or atelectasis of the lung. Early diagnosis and adequate treatment are essential to prevent pulmonary and cardiac complications and to avoid radical lung surgery.

2/39. Use of postoperative chest x-ray after elective adult tracheotomy.

    Surgeons have been creating tracheotomies since at least 124 AD, when first reported by Asclepiades (Price HC, Postma DS. ear nose Throat J 1983;62:44-59). Intraoperative and postoperative complications specifically associated with this procedure have been well established. The incidence of pneumothorax ranges from 0% to 17%, depending on the age group studied. To evaluate this complication, it is generally accepted that a postoperative chest film should routinely be obtained after a tracheotomy in adult patients. In adult nonemergent tracheotomies, the routine use of a postoperative chest film has a low yield for detecting a pneumothorax in patients without clinical findings of pneumothorax. To evaluate the use of postoperative chest x-ray in adult tracheotomy patients, a retrospective review of tracheotomies performed at the boston Medical Center from January 1994 to June 1996 was undertaken. Data examined consisted of age, sex, surgical indication, urgency, operating service, intraoperative and postoperative complications, difficulty of procedure, anesthetic technique, findings on postoperative chest film, signs and symptoms of pneumothorax, and specific treatment of pneumothorax if present. In total, 250 patients were identified. The main indication for tracheostomy in this study was ventilator dependence, accounting for 77% of the procedures. A complication rate of 11.6% was encountered, with no deaths. postoperative hemorrhage was the most common complication (3.6%). pneumothorax was documented by chest x-ray in 3 (1.2%) patients, 1 of whom had bilateral pneumothoraces. The most common symptom of a pneumothorax was tachycardia, with 8.8% of the patients exhibiting at least 1 episode. Of the 3 cases of pneumothorax in this study, only 1 was clinically relevant and required treatment. Furthermore, the clinical signs and symptoms in this patient clearly supported the diagnosis of pneumothorax before a postoperative chest film was obtained. Thus postoperative chest radiographs did not change the treatment or outcome of any of the patients undergoing a tracheotomy. This suggests that postoperative chest x-ray after adult tracheotomy is not required in routine cases. Chest radiographs should be obtained after emergent procedures, after difficult procedures, or in patients exhibiting signs or symptoms of pneumothorax.

3/39. Wegener's granulomatosis in the upper respiratory tract.

    Wegener's granulomatosis is a distinct clinico-pathological entity characterised by necrotising vasculitis of small arteries and veins in conjunction with the formation of granuloma in the upper and lower respiratory tracts, and glomerulonephritis. The vast majority of patients have antineutrophil cytoplasmic antibodies in the serum with a characteristic cytoplasmic pattern. However, in early phases of the disease only the upper respiratory tract may be affected, clinical and histological features may be nonspecific, and antineutrophil cytoplasmic antibodies not present. In this paper we present four patients with involvement of the upper respiratory tract suspicious for early Wegener's granulomatosis. We emphasise the significance of clinical, histological and serological parameters in the early detection of Wegener's granulomatosis.

4/39. Wegener's granulomatosis--a diagnostic challenge.

    Wegener's granulomatosis is a systemic vasculitis characterized by necrotizing granulomatous lesions in the upper and lower respiratory tracts, glomerulonephritis and vasculitis involving other organs. Limited forms have been described in which some features of the disease may be absent. Four patients with this disease are being reported with special emphasis on differences in presentation, the ensuing diagnostic problems, and individual outcome. In three, the disease began as a limited form with upper respiratory tract and eye involvement, while in one patient, onset was systemic including affection of the lower respiratory tract. The mean delay from first symptoms to diagnosis was 20 months--much longer for the three limited forms than for the one with systemic onset, in whom the condition was recognized after 2 months following initial misdiagnosis of respiratory and urinary tract infections. One patient developed endocarditis and required aortic valve replacement. Immunofluorescence revealed antineutrophil cytoplasmic antibodies in all, three showing a cytoplasmic pattern and antibodies to proteinase 3, and the fourth a perinuclear pattern and antibodies to myeloperoxidase. Upper respiratory tract biopsies were not specific. kidney biopsies were performed in all the patients and were crucial for definitive diagnosis and treatment of the disease, which was successful in three patients.

5/39. Evaluating and monitoring the adolescent with pulmonary function testing.

    This article reviews pulmonary function tests (quantitative measurements of physiologic functioning of lungs, chest wall, and respiratory muscles) as valuable tools for the diagnosis and management of chronic respiratory disease in adolescents. Advances in technology have made pulmonary function testing more available and, for some tests, easier to perform. Pulmonary function evaluation is used for diagnosis of pulmonary disease. Testing will identify abnormal physiologic processes that result in obstructive or restrictive pulmonary disease and, together with a complete history, physical examination, and other tests, help to determine the specific etiology. Pulmonary function measurement may be used to manage a patientis disease over time. Quantitative evaluation of the response to many specific therapies, such as asthma medications and environmental control, can only be achieved by measuring pulmonary function. Monitoring pulmonary toxicity of medications, such as chemotherapeutic agents, is also done by measuring pulmonary function. In many patients with chronic pulmonary disease, such as cystic fibrosis, the pulmonary function laboratory can be used to assess the patient's physiologic limitation.

6/39. Dacryoadenitis as the earliest presenting manifestation of systemic Wegener's granulomatosis.

    PURPOSE: To report a case presenting with dacryoadenitis as the earliest manifestation of systemic Wegener's granulomatosis (WG). DESIGN: Observational case report. methods: A 41-year-old woman initially presented symptoms of bilateral dacryoadenitis. She subsequently developed upper and lower respiratory tract involvement, scleritis and keratitis. RESULTS: Cytoplasmic antineutrophil antibody (c-ANCA) titer was positive. The lacrimal gland and lung biopsies were consistent with WG. The patient responded well to cyclophosphamide and prednisolone. CONCLUSIONS: Dacryoadenitis maybe the earliestpresenting manifestation of WG andprompt immunosuppressive chemotherapy may control it preventing the limited disease from progressing to a complete form and reducing its morbidity and mortality.

7/39. Angioneurotic edemas of the upper aerodigestive tract after ACE-inhibitor treatment.

    There are rare cases in which inhibitors of the angiotensin-converting enzyme can cause an angioneurotic edema of the upper aerodigestive tract. The pathomechanism of this side effect depends on an interaction of the drug with hormones regulating vascular permeability, such as the kallikrein kinin system and the prostaglandin system. angioedema is characterized by subcutaneous or submucosal swellings, which usually affect the lips, soft palate, tongue and larynx. Pathomechanisms, differential diagnosis and treatment of ACE-inhibitor-induced edema of the upper aerodigestive tract are described in three case reports.

8/39. Macular amyloidosis with localized amyloidosis of upper air passages.

    A patient with primary amyloidosis of the upper air passages was found to have cutaneous macular amyloidosis. A review of the literature indicates that this may represent the first report of these two uncommon forms of amyloidosis occurring in the same individual. biopsy material from the nasopharynx, tonsillar areas, larynx, trachea, and skin showed amyloid in the tissue sections. Special stains were used and polariscopic studies were performed, and the hyalin material met the established criteria for amyloid. Studies of tissues from other parts of the body of this patient failed to demonstrate amyloid.

9/39. Syndromes in amoebic liver abscess.

    A series of 137 patients with amoebic liver abscess has been studied. Recognition of clearly defined but diverse clinical syndromes was found to be necessary not only in diagnosis but also in planned surgical management. The majority of patients had the classic syndrome of fever, right abdominal or chest pain, hepatomegaly, hepatic tenderness and radiological abnormalities. Other syndromes of presentation included the silent abscess, acute amoebic colitis, the acute abdomen, the intraabdominal lump, the external sinus, pyrexia of obscure origin, obstructive jaundice and renal, pleuro-pulmonary and cardiac symptoms. The syndromes due to an abscess in different parts of the right lobe and in the left lobe of the liver are to some extent distinct. In spite of the varied modes of presentation of amoebic liver abscess, the key to diagnosis is an understanding of the chronological sequence of the disease and its progression from one syndrome to another. Diagnostic methods of value and the mortality are discussed.

10/39. Airway difficulty after a brachial plexus subclavian perivascular block.

    IMPLICATIONS: We report a case of upper airway obstruction after subclavian perivascular block in a patient with a preexisting unrecognized paralyzed vocal cord on the opposite side. We discuss the incidence of vocal cord paralysis after subclavian perivascular block and the risk of airway compromise if contralateral vocal cord paralysis is known or suspected.
