Coughing is an important protective reflex of the respiratory tract and primarily serves clearance of the bronchial system. It is also an exceptionally common symptom in outpatient care that can be an expression of a variety of diseases. Coughing duration of longer than 8 weeks is referred to as chronic cough. A structured, often interdisciplinary diagnostic process is essential. The aim here is to identify causal treatment options, avoiding overdiagnosis and simultaneously not overlooking severe illness. This article discusses current diagnostic procedures, important differential diagnoses and possible treatment options., (© 2023.

A 48-year-old-male presented with a five-week history of non-productive cough and exertional dyspnoea. A pulmonary function test showed a mild diffusion disorder. A CT scan revealed an atypical pneumonia with bipulmonary consolidations, which were accentuated in the right upper lobe. The transbronchial biopsy showed lipid-loaded macrophages. These findings confirmed the diagnosis of a lipoid pneumonia, which developed in the context of inhalation of substances containing menthol. After discontinuation of the causative agent and high-dose steroid administration the symptoms were reversible within a few weeks., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

The article describes the case of a hospitalized 58-year-old female patient with a chronic dry cough and increased inflammation values. Before hospital admission, the presence of coronavirus disease 2019 (COVID-19) was excluded by a normal chest X‑ray and two negative PCR tests on throat swabs. On admission the only symptom was a dry cough with clinically inconspicuous auscultation findings. The laboratory investigations revealed anemia and increased inflammation parameters, e.g. C‑reactive protein (CRP) 92.4 mg/l and erythrocyte sedimentation rate (ESR) 102 mm/h (according to Westergren). A large vessel vasculitis was demonstrated on magnetic resonance angiography (MRA). After the diagnosis of a giant cell arteritis, treatment with an oral glucocorticoid and subcutaneous methotrexate (MTX) was initiated, with good clinical and laboratory parameter responses. Dry cough has been described in rare cases in the literature as the first sign of large vessel vasculitis.

Cough from a pharmacological point of view Abstract. Drugs with various protussive or antitussive mechanisms of action are used to alleviate cough symptoms. Phytopharmaceuticals also play an important role. When determining the etiology of persistent cough, long-term medication should be critically assessed and on suspicion of an adverse drug reaction adjusted as necessary.

Multicentric Castleman's disease (MCD) is a rare polyclonal lymphoproliferative disorder that is typically accompanied by an overproduction of circulating cytokines (mainly interleukin-6). We here report the case of a 40-year-old HIV-negative woman with pulmonary manifestation of MCD. There is no standard treatment for MCD. In our patient, various treatment courses with immunomodulatory drugs were unsuccessful. Finally, treatment with the interleukin-6 receptor antibody tocilizumab has resulted in continual clinical improvement over the last 5 years.

There is a long list of differential diagnoses for chronic cough lasting longer than 4 weeks in children. Diagnostic work up starts with a detailed history taking and a clinical investigation followed by a chest X-ray (in one plane) and a spirometry. For the latter reliable results can be achieved by children older then 5 years. If the diagnostic work up is still inconclusive and if the child is in good clinical condition, a 4 weeks' course of inhalation therapy with steroids and betamimetics together with a 2 weeks' course of antibiotics with a macrolide is warranted. In case coughing persists a thorough diagnostic work up is indicated to rule out conditions like cystic fibrosis, relevant humoral immuno-deficiencies, primary ciliary dyskinesia, anatomic malformation or chronic pulmonary aspiration, preferably done by a pediatric pulmonologist. Chronic cough has to be considered abnormal in any child under the age of 1 year. For this age group a final diagnosis is of special importance.

Objective: For the investigation of the benefits and tolerability of a syrup made of extracts from thyme and ivy (Bronchipret Saft) in children and adolescents (ages: 2-17 years) with acute bronchitis and productive cough, a non-interventional postmarketing surveillance study was carried out., Methods: Prerequisites for participation in the surveillance study were productive cough for a maximum of two days, at least ten coughing fits per day prior to the initiation of treatment (estimation of the parents or adolescent) and a Bronchitis Severity Score (BSS) of at least five points. The primary outcome measure was the change in the clinical symptoms based on the BSS. Treatment was carried out using age-appropriate dosages prescribed by the doctor on a case-by-case basis in accordance with the summary of product characteristics. Documentation of the course of treatment for the surveillance study was to be taken on treatment days 0, 4 and 10., Results: For the descriptive, statistical evaluation of the surveillance study, the data from 1234 children and adolescents (623 boys and 611 girls) in the age groups < 2 years (N = 12), 2-5 years (N = 372), 6-11 years (N = 438) and 12-17 years (N = 412) were available. The correspondence of the dosages to the age-specific recommendations of the valid summary of product characteristics varied from 81.7% to 93.9% in the different age groups. The average BSS value decreased from 8.8 points to 4.8 on treatment day 4 and to 1.3 points after about ten days of treatment. Compared to that of the initial examination, the number of documented coughing fits had decreased on the average by 18.7 (81.3%) on day 10. The responder rates of the various age groups were 92.0% to 96.5%. The tolerability was rated as very good to good by the physicians in 96.5% of the cases. Two female patients had temporary, not serious adverse drug reactions (stomache ache, mild nausea)., Conclusion: Acute bronchitis with productive cough in (young) children and adolescents can be treated safely and effectively with the thyme and ivy syrup. A ten-day treatment using age-appropriate dosages led to a clear improvement in the symptoms or cure with very good tolerability.

Plantain (Plantago lanceolata L.) is used for the therapy of infections of the upper respiratory airways. While only few clinical data are available, results of experimental research confirm e.g. antiinflammatory, spasmolytic and immunostimulatory actions. A positive benefit-risk-ratio allows the recommendation of plantain in moderate chronic irritative cough, also especially for children.

A 57-year-old man with a cough and increasing exertional dyspnoea for the past 6 weeks was found on examination to have a loud systolic murmur and cardiomegaly with pulmonary congestion. Echocardiography revealed congenitally corrected transposition of the great arteries (cTGA: atrioventricular and ventriculoarterial discordance): a morphologically right ventricle with a tricuspid valve on the left, a morphologically left ventricle with bicuspid a-v valve on the right, the aorta arising ventrally from the left-sided (morphologically right) ventricle. The tricuspid valve showed an Ebstein-like anomaly with obvious regurgitation. Transoesophageal and contrast echocardiography defined valvar anatomy, attachment of the great arteries and cardiac chambers to the venous and arterial circulations, as well as absence of a left to right shunt. Angiography revealed a coronary anatomy typical for cTGA. The exertional dyspnoea responded to diuretics and low doses of ACE inhibitor. Follow-up monitoring of the valvar regurgitation and appropriate endocarditis prophylaxis were recommended. As the haemodynamics in cTGA is normal, in the absence of additional anomalies, it is a congenital cardiac defect which can, though rarely, present first in adulthood. Life expectancy depends on the nature of any additional defects and the degree of commonly associated tricuspid valve regurgitation. As this case demonstrates, echocardiography can largely define the anomalies.

Cough is a powerful physiological reflex mechanism that causes central airways to be cleared of foreign material and excess secretions. Chronic cough is a very common presenting symptom in general practice with a prevalence in the population of about 5%. As a general rule, persistent cough represents organic disease of the upper and lower airways, the lung parenchyma, the pulmonary circulation, the pleural space, the mediastinum and the upper gastro-intestinal tract. The most common cause is cigarette smoking, but virtually any chronic lung disease may be occasionally associated with cough. Complications of coughing are tussive syncopes, rib fractures, rupture of respiratory muscles and eventually hernias. Based on a detailed clinical history and physical examination, the investigation includes a chest radiograph, spirometry, and sputum smears. Radiography of the sinuses, bronchoscopy and upper gastro-intestinal endoscopy may be added. If the treatment of an underlying disease is successful, chronic cough may disappear. There are few 'antitussive' drugs with proven suppression of the cough reflex.

In a double-blind study involving two groups of ten patients with chronic obstructive bronchitis, the expectorant Gelomyrtol forte was tested against placebo for its effectiveness and tolerance. The parameters: amount of sputum, Rt and IGV, together with all the usual clinical laboratory parameters, were determined. In addition, the color of the sputum was always noted. On the basis of patient scores, daily entries on the ability to expectorate, attacks of coughing, general coughing, and shortness of breath were made by the patients for the duration of the 14-day treatment period. On conclusion of the study, the patients were asked to assess the effectiveness of the supplementary medication, and the care-providing physician also assessed effectiveness. All score parameters related to coughing improved, in some cases appreciably, relative to the placebo group. The findings in term of sputum volume and color, were also distinctly better in the Gelomyrtol forte group. Correspondingly, both patients and physicians assessed the effectiveness of Gelomyrtol forte to be distinctly better than that of the placebo. Although the groups are relatively too small and heterogeneous, to establish statistically significant differences, the results do strongly suggest a favorable and major effect in patients with relevant cough symptoms. Both subjective and objective tolerance was excellent.
