[Asthma in the elderly].

INTRODUCTION: Asthma in the elderly is a growing clinical problem. It affects 6 to 7% of this age-group, but making the distinction between asthma and chronic obstructive pulmonary disease is more difficult as patients get older. STATE OF THE ART: This difficulty is due to a number of factors: the confounding role of smoking, and also the physiological effects of ageing on the airways which renders airway obstruction more resistant to bronchodilation. Elderly asthmatics can be divided on clinical grounds into two arbitrary groups: "ageing asthmatics" who have had asthma since childhood or adolescence and "late-onset asthmatics" who may present following an infective episode. Certain features of asthma in the elderly include: poor perception of breathlessness, technical difficulties in making reliable pulmonary function measurements and the extrapulmonary manifestations (impact on quality of life). PERSPECTIVES: The therapeutic strategy is much the same as for younger asthmatics but certain aspects take on greater importance: concerns about osteoporosis with long-term corticosteroid therapy (both oral and inhaled), the risk of arrhythmias with beta-2 adrenergic drugs and the significant side-effects of theophylline justifies, in difficult cases, consideration of anticholinergic and/or anti-leukotriene therapy. CONCLUSION: Most importantly, for elderly asthmatics it is a treatment regimen that is as simple as possible and is backed up by a written self-management plan that will improve outcomes.

[Recurrent edema of the face and neck in a chronically hemodialyzed patient].

We report the case of a patient undergoing long-term hemodialysis admitted to hospital for diagnosis of recurrent face and neck edema influenced by dialysis sessions with paroxysmal dyspnea. We considered the possible role of allergy to ethylene oxide and to formaldehyde without diagnostic confirmation. Dialyzer complement activation was suspected but changing the dialyzer did not improve the symptoms. Anti-histaminic and corticosteroid therapy did not modify symptoms. A mild hemithoracic collateral circulation occurred and led to the discovery of a superior vena cava syndrome. Computed tomography and bilateral upper limb contrast venography visualized a thrombus in the superior vena cava extending into the right venous brachiocephalic arm from the central vein catheter. A stent was inserted into the superior vena cava which, together with anticoagulant therapy, led to rapid resolution of the symptoms. Superior vena cava syndrome related to a central catheter and hypersensitivity reactions should always be considered as possible causes of recurrent face and neck edema in patients on long-term hemodialysis.

Quality of life in nasal polyposis.

BACKGROUND: Nasal polyposis (NP) is a frequent inflammatory chronic disease of the upper respiratory tract, which may impair quality of life (QOL). The NP impact, which is frequently associated with lower respiratory disorders, has never before been studied. OBJECTIVE: We initiated this prospective study to establish internal validity and reliability of the generic SF-36 questionnaire in NP and to determine to what level daily functioning becomes impaired as a result of NP. METHODS: Forty-nine consecutive patients with NP were included. They were assessed for the severity of nasal symptoms and underwent pulmonary function tests. The QOL profiles in patients with NP were compared with those of patients with perennial rhinitis (n = 111) and healthy subjects (n = 116). RESULTS: Cronbach's coefficient alpha demonstrated the high reliability and validity of the SF-36 questionnaire for patients with NP (alpha =.89). NP impaired QOL more than perennial allergic rhinitis (P <.05). The impairment of QOL was greater when NP was associated with asthma (P <.05). SF-36 scores appeared highly correlated to pulmonary function (FEV1, maximal midexpiratory flow, forced vital capacity), suggesting relationships between QOL in NP and associated bronchial obstruction. Severity of nasal symptoms were not related to QOL scales. In addition, sequential evaluations of QOL, nasal symptoms, and pulmonary function were performed 10 months after the first evaluation in 28 patients with NP. These evaluations demonstrated that NP treatment either with nasal steroids or endonasal ethmoidectomy significantly improved both nasal symptoms and QOL without significant change of pulmonary function. CONCLUSION: Our study clearly demonstrated that the SF-36 questionnaire presented a high internal validity and reliability in patients with NP. NP impaired QOL to a greater degree than perennial allergic rhinitis. QOL improvement after NP treatment is related to nasal symptoms improvement.

[Sjögren's syndrome and necrotizing sarcoid-like granulomatosis].

We report the first description of a Sjögren's syndrome associated with nectrotizing sarcoid-like granulmatosis. A 62-year old woman was admitted for diagnostic exploration of fatigue, weight loss, and fever at 38 degrees C which had progressed for more than 3 months. Chest X-ray showed several pulmonary opacities. There was a history of tuberculosis and thyroiditis at the age of 20 years. Physical examination revealed a sicca syndrome. There was no objective evidence of respiratory disease. Her heart and chest were clear on auscultation. The patient had autoantibodies for SSa and SSb specific antigens. Minor salivary gland biopsy gave a score of 3 in the Chisholm classification. Chest X-ray and CT-scan showed diffuse infiltrative opacities which were dense and peripheral with no retraction. Bronchoalveolar lavage, and bronchial and transbronchial biopsies were non-specific. Surgical lung biopsy showed typical aspects of necrotizing sarcoid-like granulomatosis. After high-dose pulse corticosteroid therapy, the opacities disappeared with no recurrence under oral steroids at three years.
