B-mode ultrasound and contrast-enhanced ultrasound for evaluation of pneumonia: A pictorial essay.

Due to their often peripheral pleural-based location, pneumonias can be visualised by B-mode ultrasound. Therefore, sonography can be used as an alternative imaging modality to chest X-ray in suspected cases of pneumonia. Depending on the clinical background of the patient, and various underlying pathological mechanisms, a heterogeneous pattern of pneumonia is seen in both B-mode lung ultrasound and contrast-enhanced ultrasound. Here, we describe the spectrum of sonographic manifestations of pneumonic/inflammatory consolidation on B-mode lung ultrasound and contrast-enhanced ultrasound.

Acoustic Monitoring of Night-Time Respiratory Symptoms in 14 Patients with Exacerbated COPD Over a 3- Week Period.

Introduction: In clinical practice, wheezing and coughing represent a worsening of the respiratory situation of COPD patients and should be monitored long-term during and after an Acute Exacerbation of COPD (AECOPD) to observe the therapy. We investigated if overnight monitoring of wheezing and coughing is feasible during AECOPD and whether automatic long - term monitoring enables an objective assessment during and after an AECOPD. Methods: In 14 patients (age: 56-80 years) with pre-existing COPD (stages B-D) nighttime wheezing and coughing events were monitored for a period of three weeks. The portable LEOSound® monitor recorded three nights into AECOPD (nights 1, 3 and 6) during the hospital stay, and the 20th night post- AECOPD ambulatory. Before each recording the subjective symptom severity was assessed by a COPD Assessment Test (CAT) and a Modified British Medical Research Council (MMRC) dyspnoea index questionnaire. Results: In all 14 patients, lung sounds were recorded in good quality during each of the 4 recording nights. Wheezing ranged between 5% and 90% (79 -539.5 minutes) of the recording time on the first night. All patients showed some coughs, in four patients coughing was particularly pronounced and largely receding over the total investigation period. As group, the percentages of wheezing and the number of coughs did not show significant differences between the four recording times. The CAT scores (p<0.001) declined over the course of investigation period, suggesting a subjective improvement of symptoms. Conclusion: The observational study showed that standardized long-term recording can be performed in high-quality during acute COPD exacerbation as it does not require the patient's cooperation. The good-quality data of coughs and wheezing were analyzed qualitatively and quantitatively. The long-term presentation of respiratory symptoms during an AECOPD offers the opportunity to evaluate factors that influence exacerbations and therapeutic approaches.

Sleep and rheumatic diseases.

This review article discusses various forms of sleep disorders associated with musculoskeletal diseases (MD). It presents the pathophysiology and interaction of sleep-related disorders and MD and summarizes clinical symptoms and therapies from a somnological perspective. BACKGROUND: A large number of patients suffering from MD report fragmented sleep with poor overall sleep quality. Sleep disorders often lead to increased symptoms such as daytime fatigue, depression, or increased pain intensity. In contrast, the perception of pain worsens the quality of sleep. Sleep is a complex regulation of hormonal and neuromodulatory influences to maintain regenerative processes and signal processing. Furthermore, interleukins (e.g., IL-6 and TNFα), messenger substances, or inflammatory markers (e.g., CRP) may have a regulatory influence on sleep. THERAPY: Sleep disorders in MD can often be treated with behavioral therapies or drug approaches. Another and very important influence is physical activity. In combination with training, regular physical activity can lead, for instance, to improved sleep quality, endurance performance, and reduced inflammation values. The change of lifestyle with regard to activity and nutrition is another key concept in the optimal therapy of patients with MD.

[Screening and check-ups in pneumology]. / Vorsorgeuntersuchungen und Check-ups in der Pneumologie.

In pneumology, preventive check-ups have played a subordinate role so far. Current research results could change this. In the following article the focus is on lung cancer and COPD, diseases that have a considerable influence on mortality and morbidity in modern society. Approaches will be discussed that will allow earlier diagnosis of COPD or identify patients at risk. In particular Capture, a questionnaire that significantly increases the pre-test probability in COPD diagnostics, should be mentioned here. Lung carcinoma screening is a controversial topic in Germany. In an American study, the relative mortality rate from lung cancer was significantly reduced by CT screening. Results of a European study (Nelson trial) are still pending. A high pre-test probability will also be decisive for lung cancer screening. In this way, the cost-benefit ratio could be optimized. Since COPD patients have a significantly increased risk of lung cancer, there might be overlaps in the screening procedures.

[Control of Respiratory Symptoms During Sleep in Patients with Stable Bronchial Asthma]. / Nächtliche Symptomkontrolle bei Patienten mit stabilem Asthma bronchiale.

INTRODUCTION: Awareness of respiratory symptoms during day- and night-time is important for asthma control. Acoustic long-term recording offers a possibility to monitor symptoms objectively. In this prospective observational study frequency of night-time cough and wheezing was evaluated in patients with stable asthma. METHODS: Night-time cough and wheezing were monitored by LEOSound lung sound monitor in 40 patients with stable asthma. Patients did not complain of respiratory problems during day- and nighttime, asthma control test was 23 points on average. FEV1 was 84 ±â€Š15 %; MEF 50 71 ±â€Š27 % and Rtot 0,48 ±â€Š0,18 kPas/l. The age of the patients was 35 ±â€Š11 years. All patients had an antiobstructive and/or anti-inflammatory medication. The present study focuses on description of frequency, severity and characteristics of night-time symptoms like cough and wheezing in patients with stable asthma and tries to depict differences in patients who present cough or wheezing. RESULTS: Wheezing was monitored in 2 of the 40 patients. In the first patient duration of wheezing was 19 min, in the second 55 min. Lung function in patient 1 showed a moderate bronchial obstruction, he was still smoking. Patient 2 was a non-smoker with a significant bronchial obstruction (FEV1 49 %; MEF 50 27 % and Rtot 0,52 kPas/l). In 26 patients there was no coughing, 14 patients had 4 ±â€Š3 (2 - 13) cough epochs during the night. By dividing the collective in two groups differentiated by the presence of cough/ no cough we found no significant differences regarding lung function and ACT-scores. Both patients with night-time wheezing presented low ACT- Scores (20 and 21 points). CONCLUSIONS: Nocturnal wheezing and cough episodes were detectable in 2 respectively 14 patients with stable asthma. Long-term recording of normal and adventitious breath sounds offers a practical opportunity to evaluate night-time cough and wheezing objectively.

Description of nighttime cough epochs in patients with stable COPD GOLD II-IV.

PURPOSE: Chronic cough is one of the main symptoms of COPD. Ambulatory objective monitoring provides novel insights into the determinants and characteristics of nighttime cough in COPD. MATERIALS AND METHODS: Nighttime cough was monitored objectively by LEOSound lung sound monitor in patients with stable COPD II-IV. In 30 patients, with 10 patients in each stage group, nighttime cough was analyzed for epoch frequency, epoch severity (epoch length and coughs per epoch), and pattern (productive or nonproductive). RESULTS: Cough was found in all patients ranging from 1 to 294 events over the recording period. In 29 patients, cough epochs were monitored, ranging from 1 to 75 epochs. The highest amount of cough epochs was found in patients with COPD stage III. Active smokers had significantly more productive cough epochs (61%) than nonsmokers (24%). CONCLUSION: We found a high rate of nighttime cough epochs in patients with COPD, especially in those in stage III. Productive cough was predominantly found in patients with persistent smoking. LEOSound lung sound monitor offers a practical and valuable opportunity to evaluate cough objectively.
