Recurrent pulmonary infections with Staphylococcus aureus and Pseudomonas aeruginosa are a major problem in
cystic fibrosis
(CF), leading to severe and progressive deterioration of the respiratory tract. Fibronectin (FN) has a binding site(s) for S. aureus and Streptococcus pyogenes. This bacterial bindings site(s) was studied by using FN from patients with CF and comparing them with FN purified from the plasma of
bronchitis
and normal subjects by an enzyme-linked immunosorbent assay technique. We found a decreased binding of the CF FN to these bacteria in all seven CF patients. Other differences between the CF FN and normal FN were a marked modification in the pattern of peptide migration in polyacrylamide gel electrophoresis after hydrolysis with various proteinases and an increase or decrease of the total sugar content of the FN.

Expectoration of bronchial casts (plastic
bronchitis
) is an uncommon but ancient problem. Herein we describe a 40-year-old man, with no prior lung disease, who had dyspnea, cough, and expectoration of long branching bronchial casts. No specific cause was delineated, although special stains for eosinophilic granule major basic protein demonstrated occasional foci of eosinophils and small amounts of extracellular major basic protein in the bronchial casts. Various diseases, such as allergic bronchopulmonary aspergillosis, bronchiectasis, and
cystic fibrosis
, have been associated with the formation of bronchial casts and should be considered in the differential diagnosis. Although most previously reported cases have been associated with some type of pulmonary disease, our patient had no evidence of an underlying pulmonary disorder.

The chronic, progressively destructive
bronchitis
of patients with
cystic fibrosis
(CF) is characterized by an important imbalance between tissue destroying granulocyte proteases such as granulocyte elastase (GE) and its physiological inhibitors in bronchial secretions. Recent in vitro studies suggest, that proteases derived from bacteria or endogenous proteases may contribute to inactivation of physiological inhibitors of GE. Since only trypsin-unreactive alpha 1-proteinase inhibitor (alpha 1-PI) was detected in CF bronchial secretions, we attempted to identify the mechanism of inactivation of alpha 1-PI. We found a heat stable, serine protease-like enzymatic activity capable of degrading 125I-labelled alpha 1-PI extensively in 22 infected but not in one non-infected CF bronchial secretion. In infected secretions, only degraded alpha 1-PI, which did not migrate like oxidized alpha 1-PI in tandem-crossed immunoelectrophoresis, was detectable. We conclude, that free GE in excess as well as GE bound to bronchial mucosal inhibitor may partly account for the alpha 1-PI-cleaving activity, but that other yet unknown bacterial or host serine proteases also contribute to alpha 1-PI inactivation.

Autonomic nervous system function has been studied both in vitro and in vivo using a variety of methodologies. In asthmatic patients, beta-adrenergic hyporesponsiveness and alpha-adrenergic and cholinergic hyperresponsiveness can be frequently demonstrated. These observations have provided support for the beta blockade theory of asthma, advanced in the late 1960s by Andor Szentivanyi's experiments involving sensitized rodents. However, in addition to asthma, aberrations in autonomic nervous system function have been noted in other individuals including
cystic fibrosis
patients and their parents, patients with emphysema and
bronchitis
, and in patients (allergic rhinitis and atopic dermatitis) who have demonstrable IgE antibody responses to a variety of antigens. Thus, although these defects are not specific for asthma, it is noteworthy that these conditions share many clinical features; the ultimate phenotypic expression of these abnormalities may depend on both genetic and environmental factors that have yet to be defined.

Respiratory distress and progressive lung destruction in
cystic fibrosis
can be attributed to bacterial persistence and the accumulation of viscous purulent secretions in the airways. More than 30 yr ago it was suggested that the large amounts of DNA in purulent secretions contribute to its viscosity and that bovine pancreatic DNase I could reduce the viscosity. To evaluate the potential clinical utility of recombinant human DNase I (rhDNase) in the treatment of
cystic fibrosis
, we have cloned, sequenced, and expressed rhDNase. Catalytic amounts of rhDNase greatly reduce the viscosity of purulent
cystic fibrosis
sputum, transforming it within minutes from a nonflowing viscous gel to a flowing liquid. The reduction in viscosity is associated with a decrease in size of DNA in the sputum. Inhalation of a rhDNase aerosol may be a simple direct approach that will help individuals with
cystic fibrosis
and other patients with pneumonia or
bronchitis
to clear their airways of purulent secretions.

The authors report a case of pregnancy in a patient suffering from moderately severe
cystic fibrosis
(the syndrome consisted of diffused obstruction in respiratory function with a vital capacity of 79% and the lowered blood oxygen level with arterial blood gas estimations; oxygen saturation was 94%). The condition was marked by temporary worsening during the pregnancy in which infective
bronchitis
supervened). She also threatened to go into early labour and did in fact deliver at 36 1/2 weeks of an infant which was normal for the duration of the maturity. The authors review previous known facts about
cystic fibrosis
. A study of the literature has made it possible to be more accurate in describing methods of ante natal diagnosis of the condition and ways of following the pregnancy and the illness as well as the woman's fertility and her ability to breast feed.

The results of the investigations to reference values for Na(+)- and Cl(-)-concentrations in sweat of adults are as follows: The normal range of electrolyte values in sweat in adults is up to 70 mmol/l (Na+) and 55 mmol/l (Cl-) respectively in infants (40 mmol/l for Na+ and Cl-). There are no sex and age differences. Adults with chronical
bronchitis
and bronchiectasis don't show different results in comparison with healthy persons. Adults with
cystic fibrosis
have significantly increased sweat electrolyte concentrations (90-120 mmol/l). Variations in the electrolyte values of a day or of a month are important and much higher than the analytical one.

Patients with asthma who have incomplete control of their symptoms or require regular systemic steroidal therapy are said to have recalcitrant asthma. A systematic approach may significantly improve quality of life. Factors that should be evaluated include living with an antigen, occupational exposure, use of beta-adrenoreceptor blockers, use of nonsteroidal anti-inflammatory agents, sensitivity to dietary chemicals, endocrinopathies, gastroesophageal reflux, sinusitis, bronchopulmonary aspergillosis, and noncompliance. Other diseases may mimic asthma or exacerbate nonspecific bronchial hyperreactivity. These include congestive heart failure, chronic infectious
bronchitis
resulting from
cystic fibrosis
, ciliary dysfunction syndrome, and immunodeficiency syndromes, upper airway obstruction, pertussis syndrome, psychogenic coughs, bronchiolitis obliterans, chronic eosinophilic pneumonia, and vasculitides. A systematic approach to the evaluation of coexisting factors and potential exacerbating diseases is presented.

Whooping cough is endemic throughout the world. It becomes epidemic every 4-5 years (Yugoslavia 3-4 yrs). In Europe its incidence ranges from 0.4 (Hungary) to even 59/100.000 inhabitants (Rumania; Yugoslavia 28), with a general letality of 0.1% (infants: 1%; 75% children who die are younger than one yr). Only 5-10% cases are supposed to be registered. A low socioeconomic status is more and more emphasized as the principal risk factor. Its transmission rate is high (home contacts: 80-100%); infectivity lasts five weeks, disease from the beginning of incubation to the sanation lasts 50-60 days. Female children are more frequently affected. The term "Pertussis syndrome" is more end more used because a similar disease can be caused by various agents (B. pertussis; B. parapertussis: 5%-20%-30% cases; B. bronchiseptica rarely; adenoviruses, RS virus, parainfluenza virus, influenza A and B virus, HSV, CMV, EBV, entero-, adeno-, corona-, rota-viruses; chlamydiae and mycoplasmae). Prior to introducing vaccination, 95% of population have had a typical or atypical form of pertussis. Its differential diagnosis includes pneumonias of various etiology,
bronchitis
, bronchiolitis during an acute respiratory infection, bronchial asthma,
cystic fibrosis
, tuberculosis and lymphadenopathy. Morbidity in USA was reduced by vaccination from 157 to 0,5-1,5/100,000 inhabitants; in SR Croatia it was six times reduced in period 1959-1970. According to the official sources 81% of children in Croatia and Yugoslavia get primovaccinated; the 80% level is generally accepted as a rational goal. Immunization schedules differ from country to country. Local and general reactions after combined vaccines are mostly caused by pertussis component.(ABSTRACT TRUNCATED AT 250 WORDS)

Cases of children with obstructive
bronchitis
are presented, which were referred due to a suspicion of bronchial asthma,
cystic fibrosis
, congenital errors of the large vessels, immunological disorders, and bronchial foreign bodies. The correct diagnosis of obstructive
bronchitis
led to resolving of symptoms in part of the children.
