    Description / Table of Contents: Zusammenfassung Cromolyn (Lomudal, Intal, Aarane) nimmt einen wichtigen Platz in der modernen Asthmatherapie ein. Kombiniert man es mit Betastimulatoren (die die cyclische AMP der Mastzellen aktivieren, hiermit die Degranulation der Mastzelle hemmen und an den Bronchiolen direkte antiallergische Wirkungskomponenten haben), so erzielt man mit Cromolyn über die Hemmung der Phosphodiesterase (welche den Abbau der cyclischen AMP fördert) einen idealen antianaphylaktischen Synergismus: die Mastzelle wird vor der Degranulation optimal geschützt, und asthmagene Mediatoren, das Produkt der Degranulation, werden nicht oder nur in geringem Maß freigesetzt. Cromolyn wird in Pulverform wenn irgendwie möglich vor dem Ausbruch des Anfalles mit dem Spinhaler inhaliert. In der Regel treibt man eine systematische Langzeitprophylaxe, indem man zu Beginn täglich 4mal 20 mg, also 4mal eine Kapsel — nach erfolgter Bronchospasmolyse mittels Betastimulation — tief in die Luftwege einatmet. Steroid-abhängigen Asthmatikern kann man unter Cromolyn meist die Unterhaltungsdosis Prednison langsam und vorsichtig etwas senken. Beim Anfallsasthma mit Allergie vom Soforttyp I hat man — vor allem im Kindesalter — die größten Chancen auf Linderung der Beschwerden. Das perenniale Asthma und die chronische reversible, eosinophile Asthmabronchitis bilden zwar ebenfalls Indikationen für Cromolyn, vor allem wenn das Mittel die Patienten erwiesenermaßen vor dem Anstrengungs-induzierten Bronchospasmus zu schützen vermag, doch ist die Erfolgsquote geringer als bei der ersterwähnten Indikation.
    Notes: Abstract Cromolyn (Lomudal, Intal, Aarane) plays an important role in the modern therapy of bronchial asthma. Its combination with a betastimulator activating the cyclic AMP of the mast cells, inhibiting their degranulation and developing an antiallergic activity directly on the bronchioles, leads to an optimal antianaphylactic synergy; indeed, Cromolyn inhibits the mast cells phosphodiesterase (which inactivates the cyclic AMP) and therefore protects the mast cell against the degranulation (like the betastimulators) and prevents synergistically the release of asthma mediators. Cromolyn has to be inhaled deeply into the airways with a Spinhaler after a betastimulator-induced bronchodilatation. If possible, the drug is to be taken before the signs and symptoms of an asthmatic attack. The mode of application most often used is long-term treatment with a dosage of 20 mg 4 times, or a spincap 4 times, per day. Frequently steroid-dependent patients can, slowly and with caution, lower the daily prednisone dose somewhat. Sudden withdrawal from Cromolyn and Prednisone must be avoided. Cromolyn treatment of extrinsic asthma with immediate allergy type I is most successful, especially in children. Perennial asthma and asthmatic bronchitis may also respond to Cromolyn, particularly when the bronchial obstruction is partly reversible, when a moderate eosinophilia of the bronchial secretions is present, and when an exercise-induced bronchoconstriction is prevented by Cromolyn.

    Description / Table of Contents: Zusammenfassung Die allergische Alveolitis ist eine schubweise oder chronisch verlaufende Bronchiolo-Alveolitis zufolge Inhalation organischen Staubes. Es handelt sich vorwiegend um eine Immunopathie vom Typ III (Arthus-Phänomen der Lunge); präzipitierende Antikörper zirkulieren im Serum. Die Diagnose stützt sich auf Anamnese, klinischen Verlauf, radiologischen Befund und die meist vorliegende restriktive Lungenfunktionsstörung mit alveolokapillärem O2-Block, die bei Expositionsprophylaxe reversibel ist, schließlich auf den positiven Ausfall der Präzipitinanalyse, deren diagnostische Aussagekraft jedoch nicht überwertet werden darf. Bei uns ist die Farmerlunge die häufigste allergische Alveolitis. Sie wird als Prototyp eingehend geschildert, insbesondere auch ihre Behandlung und Vorbeugung.
    Notes: Abstract Allergic alveolitis is a bronchiolo-alveolar lung disease caused by the inhalation of organic dust. It can take either an acute or chronic course. The immunological response of the lung is mainly of Type III (Arthus reaction of the lung). Precipitating antibodies can be found in the serum. Clinical diagnosis should be based on the following points: patient's history, clinical course, radiological findings, restrictive lung function pattern with an alveolocapillary O2-block (generally reversible after removal of the patient from the dust environment and, in some cases, hard to recognize when an obstructive lung disease is also present), and positive serological tests. Indeed, precipitating antibodies can be demonstrated in most of the acute cases. In our country farmer's lung is the most common allergic alveolitis. Its prevention and treatment are discussed.

    Notes: Abstract In 7 normocapnic patients with hypothyroidism pulmonary gas exchange was measured before and after successful hormonal treatment. The results were compared with those of 8 healthy control subjects matched with the patients made euthyroid by treatment in relation to their age, sex, body height, and body weight. Hypothyroidism in patients with normal arterial pCO2 was found to be associated with a lung defect consisting of a very low physiological dead space and an arterial hypoxemia (low arterial pO2 and high alveolar arterial O2 gradient). This hypoxemia is due in part to an intrapulmonary right-to-left shunt that disappears during a short-term increase in tidal volume by connecting an external dead space. In spite of the fact that the patients were made euthyroid by treatment, a slight degree of arterial hypoxemia was always present. This hypoxemia may be a residual sign of hypothyroid lung disease. The latter may also cause the decrease in dead space volume and the intrapulmonary right to left shunt. It is possible that the hypothyroid lung disease (not recognisible by either clinical or radiological examination of the lungs) is related to the fact thatL-thyroxine plays an important role in the regulation of pneumocytes II and the synthesis of the normally functioning alveolar surfactant.

    Notes: Abstract The CO2, O2, and N2 gradients between alveolar air and arterial blood were measured during a mild steady-state exercise test in three groups of non-smoking men, 20–29, 40–49, and 63–70 years old, respectively. Breathing a low O2-mixture (15.8% O2) the (a-A) D CO2 and the (a-A) D N2 decreased during exercise, compared to room air breathing, when the same exercise level was imposed, indicating a more homogeneous distribution of alveolar ventilation and perfusion under the influence of hypoxia. However, the (A-a) D O2 remained constant during both conditions, i. e. room air and hypoxia breathing. It is well known that the O2 gradient increases under both conditions with age. The failure to demonstrate an (a-A) D N2 when a large (A-a) D O2 is present, suggests the presence of large compartments of the lungs with a low diffusion/perfusion relation (rarification of capillaries and a relatively high number of shortly segmented capillaries). The low diffusion/perfusion regions seem to contribute much more to the large (A-a) D O2 than do the less important low ventilation/perfusion compartments. Such a constellation of maldistibution between alveolar ventilation, diffusion, and perfusion seems to be characteristic for the aging lung of non-smokers performing mild exercise.

    Notes: Abstract Beclomethasone dipropionate (0.4 mg daily) or its propellent carrier alone used as placebo (oleic acid and fluorens) was inhaled by a group of sixteen otherwise non steroid treated asthmatic patients with stable perennial asthma. The mean FEV1 was 1780 ml and increased by more than 20% (mean 47%) after orciprenaline aerosol. The double blind controlled study lasted three weeks. Weekly control assessment at 8 a. m. included arterial blood gas sampling for plasma cortisol level, white blood cell count and blood gas analysis, followed by spirometry and clinical evaluation. Prior to control assessment, the last beclomethasone or placebo aerosol was taken at midnight. No significant improvement of lung function was observed in the beclomethasone group or in the placebo group. Systemic side effects were seen in both groups. The group inhaling the propellent carrier alone showed a significant increase in the basal plasma cortisol level and the absolute blood eosonophil count at the end of the second and the third week of the study. In contrast, in the beclomethasone group a significant decrease of the plasma cortisol level and the absolute blood eosinophil count was observed at the end of the second and third week. During the beclomethasone inhalation the absolute blood neutrophil count increased significantly, whereas during the inhalation of the propellent carrier alone the absolute blood monocyte count rose significantly. It thus appears that the propellent carrier of beclomethasone dipropionate has plasma cortisol mobilizing properties and stimulates cellular immune defenses through an uncertain mechanism. The systemic activity of the propellent carrier of beclomethasone produces an effect apparently opposite to the systemic side effects of beclomethasone aerosol.

    Notes: Abstract Four healthy firemen worked on the bicycle ergometer during four steps: (1) without a mask; (2) with a mean mask pressure equal to atmospheric pressure; (3) with a slight positive mean pressure of + 3.1 cm H2O inside the mask; (4) with a higher positive mean pressure of + 6.3 cm H2O inside the mask and a minimal mask pressure of + 2.2 cm H2O. Intraesophageal mean pressure increased only half as much as mask pressure. Only a slight tachycardia and a slight arterial hypotension was seen in step 4 compared to the control steps. Accordingly, a moderate increase of the preejection period (PEP) and a decrease of the left ventricular ejection time (LVET) was recorded, leading to a rise of the PEP/LVET ratio (left ventricular dysfunction). In contrast, no trace of arterial hypoxemia was seen. Opening of closed airways may explain this unexpected result. The new positive pressure respirator used in this study seems to be suitable for rescue work in smoke and toxic gases. The following preconditions have to be remembered: (1) The mean pressure in the mask should never exceed + 6.5 cm H2O; (2) a fireman's physical performance seems to be reduced to 2000–2500 ml/min O2 uptake; (3) the upright body position may increase positive pressure-induced tachycardia and arterial hypotension.

    Notes: Abstract Two asthmatic patients, 19- and 23-year old men, had evidence of deep inspiration-induced bronchoconstriction: a gradual decrease of their VC was observed when measured consecutively. After 20 and 6 weeks, the deep inspiration-induced bronchial obstruction was again observed with the same intensity. On the next 2 days a double-blind cross-over trial was started with cromolyn. The patients inhaled the placebo or the drug 30 minutes before spirometry was performed. After the placebo the deep inspiration-induced bronchoconstriction was reproduced a second time. After cromolyn inhalation, however, deep inspiration-induced bronchoconstriction was prevented completely in one case, and by three-fourths in the other. It is therefore possible that mast cell degranulation may be involved in the mechanism of deep inspiration-induced bronchoconstriction. With respect to the sudden, immediate response, however, it seems more probable that cromolyn may act upon the cough or stretch receptors or the end-plates of the efferent vagal impulses, inhibiting directly the reflex bronchoconstriction.

    Notes: Abstract The outpatient unit for respiratory diseases (Department of Internal Medicine at the University of Berne) is studying the possibilities of making optimal use of the wealth of information of the most interesting and difficult cases, collected while carrying out its routine duties. The feasibility of an information system for the unit depends mainly on two features. It must be handled by the present staff without excessively increasing its work load. It must accept precisely defined information (particulars of the patients, results of physiologic measurements, and laboratory tests) as well as free text. An information system, which seems to satisfy these criteria, is STAIRS, a program product of IBM. The information available about each patient (including free text) has been structured in such a way that it can be processed by STAIRS. There is today no general solution to the problem of semantic text analysis. The present paper discusses how clinically meaningful information can be extracted from the text stored in STAIRS data bases in order to be used in conjunction with fixed format data. It is pointed out that the use of free text imposes the obligation of a disciplined choice of words and syntax upon the user.
