Only a few earlier clinical radiologic reports exist describing post-COVID-19 pulmonary fibrosis. We report a case of 74-year-old woman referred with dizziness and hypoxemic respiratory failure with chest high resolution computer tomography (HRCT) showing ground glass opacities and emphysema. The patient was tested for Sars-CoV-2 and resulted positive, she was treated with medical therapy and supported with mechanical ventilation. Despite initial clinical and radiological improvements, subsequently the respiratory failure worsened as ground glass opacities evolved, with the appearance of combined pulmonary fibrosis and emphysema and the patient eventually died. Development of pulmonary fibrosis after SARS-CoV-2 infection and the overlap with preexistent emphysema could be a fatal complication.

Background Health-related quality of life (HRQoL) impairment is often reported among COVID-19 ICU survivors, and little is known about their long-term outcomes. We evaluated the HRQoL trajectories between 3 months and 1 year after ICU discharge, the factors influencing these trajectories and the presence of clusters of HRQoL profiles in a population of COVID-19 patients who underwent invasive mechanical ventilation (IMV). Moreover, pathophysiological correlations of residual dyspnea were tested. Methods We followed up 178 survivors from 16 Italian ICUs up to one year after ICU discharge. HRQoL was investigated through the 15D instrument. Available pulmonary function tests (PFTs) and chest CT scans at 1 year were also collected. A linear mixed-effects model was adopted to identify factors associated with different HRQoL trajectories and a two-step cluster analysis was performed to identify HRQoL clusters. Results We found that HRQoL increased during the study period, especially for the significant increase of the physical dimensions, while the mental dimensions and dyspnea remained substantially unchanged. Four main 15D profiles were identified: full recovery (47.2%), bad recovery (5.1%) and two partial recovery clusters with mostly physical (9.6%) or mental (38.2%) dimensions affected. Gender, duration of IMV and number of comorbidities significantly influenced HRQoL trajectories. Persistent dyspnea was reported in 58.4% of patients, and weakly, but significantly, correlated with both DLCO and length of IMV. Conclusions HRQoL impairment is frequent 1 year after ICU discharge, and the lowest recovery is found in the mental dimensions. Persistent dyspnea is often reported and weakly correlated with PFTs alterations. Trial registration NCT04411459.

This paper summarizes the presentations submitted for publication of the 12th AIST National Congress (Associazione Italiana Studio Tosse/Italian Association for Cough Study) entitled “The thousand facets of cough. A clinical and therapeutic update”, which occurred last February 2nd-3rd, 2018 in Bologna (Italy). It summarizes the contributions from leading experts of the sector, who, as in the previous editions, also this year have analyzed a problem too often underestimated which still has many dark sides as regards both the diagnosis and the therapy of cough. The Scientific Committee has chosen topics that had less space in previous editions and these are topical subjects representing a concrete opportunity for learning and comparison of opinions, as well as indispensable elements for the correct management of the symptoms. Hereby we report the abstracts of the works submitted for publication in this Meeting report. The main topics have covered Cough relationship with nerve vagus, ATP, air pollution, GERD, imaging, COPD, pediatric and therapy. Of particular interest it is the preliminary data on cough hydration ratio that shows a highly significant correlation between dehydration and cough.

Background Adult onset Still disease (AOSD) is a rare condition characterized by elevated fever along with arthritic symptoms, elevated polymorphonuclear neutrophil count, evanescent rash, and hyperferritinemia. Diagnosis can be made only after have ruled out more frequent conditions, and Yamagouchi or Fautrel criteria should be applied. Parenchimal lung involvement (PLI) is present in less than 5% of AOSD cases and ranges from aspecific reticular interstitial opacities to life threatening conditions, such as acute respiratory distress syndrome (ARDS). Case We report the case of a 59 years old man who was referred to our ward because of high fever treated as a pneumonia with antibiotic but not responding to medical treatment, and findings suggestive of interstitial lung disease prevalent in the lower zone on high resolution computed tomography (HRCT). AOSD was diagnosed when the diagnostic Yamaguchi criteria were fulfilled and our suspect was confirmed by the rheumatologist; the patient was then successfully treated with corticosteroids. Conclusions PLI in AOSD is very rare but must be considered among differential diagnosis in patients with high fever and aspecific interstial parenchimal lung involvement.

The management of both acute and chronic cough requires a systematic and comprehensive approach. Despite the approved protocols for management, the pediatric assessment of cough and the corresponding prescribing attitude frequently do not fit these protocols, which can be affected by parental suggestions – sometimes substantially. Objective: The objective of this study was to investigate both the perception and the behavior of a representative sample of Italian pediatricians toward cough in real life. Methods: A specific questionnaire consisting of 18 questions was prepared. The questionnaire was completed by 300 pediatricians (all members of PAIDOSS: Italian National Observatory on Health of Childhood and Adolescence) who represented ~300,000 children. Results: A vast majority of children have cough throughout the year (99.3% of respondents have cough during autumn/winter and 64.7% in spring/summer). Allergic disease is the most frequent suspected cause of chronic cough in children (53%), and this is supported by the high demand for consultations: 73% seek the opinion of allergologists, 62% of otorhinolaryngologists and only 33% of pulmonologists. The majority of pediatricians (92%) reported that they prescribe therapy in acute cough regardless of cough guidelines. Moreover, the survey pointed out the abuse of aerosol therapy (26% in acute cough and 38% in chronic cough) and of antibiotics prescription (22% in acute cough and 42% in chronic cough). Conclusion: Our survey suggests that some Italian pediatricians’ therapeutic attitudes should be substantially improved in order to achieve better management of cough in children and to minimize the burden of cough.

Objective: During the last decades, an increase in the prevalence of asthma and other allergic diseases has been recorded, together with modifications in the living environment and consequent changes in the quality of indoor air. Indoor environment is favorable to the proliferation of allergens such as: house dust mites, fungal spores and cockroaches. The primary action to be undertaken for an effective eradication of infectious agents constitutes in modifying the house environmental conditions, which make it favorable to infestations. Ozone can play a sanitize role, but at the same time it can cause inflammation, especially in the lung. The aim of this study was to verify the role and safety of ozone in the sanitation of the bedroom of a subject suffering from asthma. Methods: A daily ozone treatment was carried during a 14-day time period in the bedroom of an asthmatic patient. Aerobiological sampling in indoor air, microbiological sampling and detection of ATP bioluminescence on the surface were performed before and after treatment at the first day, as well as after treatment at the 7th and 14th day of the study. An aerobiological measurement was also performed outdoor of the patient's bedroom only for the first day. Results: Our analysis confirms that low ozone levels induced a marked reduction of indoor air microbiological pollution without adverse effects on lung functionality of the asthmatic patient we considered. Conclusion: Our observations warrant further investigation on the role that ozone-based sterilization might have in controlling asthmatic symptoms.

Background Cough is one of the most common discomforts affecting general population, which can disrupt subjects’ quality of life due to its physical, social, and psychological effects. Aim of the study was to investigate the impact of cough and related beliefs of general population. Methods A cross-sectional telephone survey was carried out by means of a specific, validated questionnaire on a representative sample of Italian general population. All the interviews were carried out according to the Computer Assisted Telephone Interview (CATI) methodology by expert, professional interviewers. Distributions of all answers were calculated in the overall sample. Results A total of 1,251 subjects (mean age: 49 years; females 44.2 %) completed the interviews. The overall number of telephone calls was 5362, and the corresponding redemption rate was 1/4.3 (23.%). The sample was representative of national population in terms of geographical distribution, age, gender, and smoking habit. The majority of respondents was convinced that cough is merely a symptom of several different diseases, but 46.4 % of respondents affirmed that cough should be regarded as “a disease” per se. Only 29.1 % of subjects say that they usually do not complain of any cough over the year, while 18.4 % reported ≥ 3 episodes of cough/year. These episodes have a duration ranging 10–30 days in 19.9 % of subjects, and > 30 days in 6.9 % of subjects. The majority of respondents is worried about their cough only after 1 week, but 76.9 % of subjects is much more worried if cough affects a child. After a few days of cough, 23.1 % of subjects use domestic remedies; 20.9 % ask their pharmacist, and 33.4 % their doctor, being GPs (69.6 %) and lung physicians (16.2 %) the most asked professionals. The occurrence of bronchitis, pneumonia, upper airway infections, and allergic troubles are the most feared events. The majority of respondents are convinced that antibiotics and steroids should not be regarded as the gold standard for treating persistent cough (61.2 and 58.2 %, respectively), while anti-tussive drugs and aerosols in general are regarded as the most effective strategies (69.1 and 74.1 %, respectively). Moreover, 33.8 % of the sample is in favour of homeopathic drugs, while 23.2 % had already used an homeopathic anti-tussive syrup, and 27.6 % of subjects are really interested in using the homeopathic approach. The willingness to pay for an effective anti-tussive remedy was: 46.3 % up to 10 €; 27.8 % up to 20 €, and 13.3 % more than 20 €. Conclusions Cough confirms its high impact in Italy, and a substantial proportion of individuals regards cough as “a disease”. Only one out of three Italians refers to their doctor, but when cough is already persistent. Cough in children is much more feared than in adults. The majority of Italians have a proper and conservative position versus both antibiotic and the systemic steroid uses against cough. The Italian attitude to aerosol therapy confirms very high. Differently from the cough guidelines, anti-tussive drugs are highly valued among Italian people. The attitude and the interest to homeopathic anti-tussive remedies proves high. Finally, the willingness to pay for an effective anti-tussive remedy is quite high in Italy.

Post-viral cough is a type of cough originating from upper respiratory tract infections that persists after the infection is resolved. Although it was hypothesized that bronchodilators might have a role in the management of post-viral cough, a clear demonstration of their efficacy is missing. Therefore, we tested the efficacy of a combination of a β-agonist and an anticholinergic agent in reducing post-viral cough with a randomized, double blind, placebo controlled clinical trial. Patients were treated for 10 days with either a nebulized combination of salbutamol 1.875 mg/0.5 mL and ipratropium bromide 0.375 mg/0.5 mL, or a placebo, and followed up for another 10 days. Daytime and nighttime cough severity and spirometry testing were assessed before starting treatment, after 10 and 20 days. Ninety-two patients were randomized to receive placebo (n = 46) or the active treatment (n = 46); nine of them (4 in the placebo group, 5 in the active treatment group) dropped out from the study. Daytime and nighttime cough severity were significantly reduced in both groups during the study period, but the reduction was more prominent in the active treatment group vs. placebo after 10 days of treatment (P = 0.003 for day cough; P = 0.061 for night cough), whereas at the end of follow-up period cough severity was comparable between the two groups. Small but significant increases in spirometric parameters were observed in the active treatment vs. placebo group, although at the end of follow-up these values returned to be comparable to placebo. The frequency of adverse events was not significantly different between the two groups of patients. We concluded that a combination of a β-agonist and an anticholinergic agent can effectively reduce post-viral cough, and can thus represent a valid option for this type of cough.

Background. The effectiveness of a homeopathic syrup on cough has been demonstrated in an adult population in a previous double-blind randomized study. The present prospective observational study investigated children affected by wet acute cough caused by non-complicated URTIs, comparing those who received the homeopathic syrup versus those treated with the homeopathic syrup plus antibiotic. Objectives. The aims were: 1) to assess whether the addition of antibiotics to a symptomatic treatment had a role in reducing the severity and duration of acute cough in a pediatric population, as well as in improving cough resolution; 2) to verify the safety of the two treatments. Methods. Eighty-five children were enrolled in an open study: 46 children received homeopathic syrup alone for 10 days and 39 children received homeopathic syrup for 10 days plus oral antibiotic treatment (amoxicillin/clavulanate, clarithromycin, and erythromycin) for 7 days. To assess cough severity we used a subjective verbal category-descriptive (VCD) scale. Results. Cough VCD score was significantly (P

Cough is a frequent symptom associated to upper respiratory tract infections (URTIs) and, although being self-limiting, it might deeply affect the quality of life. Homeopathic products are often employed by patients to treat cough, but the evidence on their efficacy is scarce. Thus, we tested the efficacy of a homeopathic syrup in treating cough arising from URTIs with a randomized, double blind, placebo controlled clinical trial. Patients were treated with either the homeopathic syrup or a placebo for a week, and recorded cough severity in a diary by means of a verbal category-descriptive score for two weeks. Sputum viscosity was assessed with a viscosimeter before and after 4 days of treatment; patients were also asked to provide a subjective evaluation of viscosity. Eighty patients were randomized to receive placebo (n = 40) or the homeopathic syrup (n = 40). All patients completed the study. In each group cough scores decreased over time, however, after 4 and 7 days of treatment, cough severity was significantly lower in the homeopathic group than in the placebo one (p < 0.001 and p = 0.023, respectively). Sputum was collected from 53 patients: in both groups its viscosity significantly decreased after 4 days of treatment (p < 0.001); however, viscosity was significantly lower in the homeopathic group (p = 0.018). Instead, the subjective evaluation did not significantly differ between the two groups (p = 0.059). No adverse events related to any treatment were reported. We concluded that the homeopathic syrup employed in the study was able to effectively reduce cough severity and sputum viscosity, thereby representing a valid remedy for the management of acute cough induced by URTIs.

Cough is a frequent symptom reported in general practice consults. Even though most of the cases concern acute and self limiting episodes, if cough persists a comprehensive diagnostic evaluation should be started. Patients that scarcely respond to empiric therapy or whose symptoms are not clearly referable to one of the most common causes of cough may receive the diagnosis of unexplained cough. These patients frequently develop depression or social retirement. Recent studies have suggested that hypersensitivity of the cough reflex could be the pathogenic mechanism underlying unexplained cough. However hypersensitivity syndrome should not be used as an easy way out for patients with a complicated history of cough. Through our paper we will briefly review the most common causes of cough and how they could be involved in the development of hypersensitivity cough syndrome.

Heart rate variability (HRV) non-invasively assesses the activity of the autonomic nervous system. During the past 30 years, an increasing number of studies have related the imbalance of the autonomic nervous system (as assessed by HRV) to several pathophysiogical conditions, particularly in the setting of cardiovascular disease. Sudden death, coronary artery disease, heart failure, or merely cardiovascular risk factors (smoking, diabetes, hyperlipidemia, and hypertension) are the best-known clinical circumstances that can affect and/or be affected by the autonomic nervous system. Analyses of HRV variables have been proposed as a component of the clinical evaluation for patient risk stratification due to its independent prognostic information. Yet the potential for HRV to be used widely in clinical practice remains to be established.
