Mezi vzácné příčiny dušnosti patří obrovský bulózní emfyzém, jinými slovy syndrom mizející plíce. Jedná se o bulu nebo buly vyplňující alespoň jednu třetinu hrudníku a utlačující okolní plíci s typickým radiologickým nálezem často zaměňovaným za pneumotorax. Předkládaná kazuistika ilustruje diagnostické a terapeutické rozpaky i omyly týkající se tohoto syndromu, včetně jeho komplikací, a zamýšlí se nad prováděním uvážlivých vyšetření a zákroků v medicíně 21. století.
Rare causes of dyspnoea include giant bullous emphysema, otherwise called vanishing lung syndrome. It is a bulla or bullae filling at least one third of the chest and oppressing the surrounding lung with a typical radiological finding often mistaken for pneumothorax. The presented case report illustrates diagnostic and therapeutic doubts and mistakes regarding this syndrome, including its complications, and contemplates performing judicious examinations and procedures in the 21st century medicine.
Respirační symptomy a alterace celkového stavu u pacientů léčených na uroteliální karcinom Bacillus Calmette-Guérin (BCG) vakcínou by měly být dávány do souvislosti s podáním této vakcíny. Může se jednat sice o vzácnou, ale známou komplikaci – BCGitis. V této kazuistice uvádíme případ staršího muže s granulomatózním zánětem plic, u kterého se BCG pneumonitida rozvinula. Dále je v článku uveden diagnostický proces tohoto onemocnění a terapie z pohledu pneumologa.
Respiratory symptoms and alterations of the general condition of patients treated for urothelial cancer with the BCG vaccine should be associated with the administration of this vaccine. The diagnosis may be a rare but well-known complication – BCGitis. In this case report, we describe the case of an elderly man with granulomatous pneumonia who developed BCG pneumonitis. Furthermore, the article presents the process of diagnosing this disease and therapy methods from the point of view of a pulmonologist.

The COVID-19 pandemic influenced the work of employees across all continents. This article presents raw data that may be used to describe how the pandemic affected the work of employees in four European countries and how it influenced their job attitudes, feelings and work performance. In total, 726 respondents from Germany, the Czech Republic, Slovakia and Italy filled out an extensive online survey and provided information about changes in their workload, work difficulty, income, social contact, work from home, task performance and organizational commitment during the pandemic, and about the risk of being infected by COVID-19 during their workday. The employees also reported their actual work performance, organizational commitment, job satisfaction, intention to leave and irritation in the time of the pandemic. To reveal factors that might help employees cope with pandemic, the respondents filled out established questionnaires measuring servant leadership of their supervisor, perceived organizational support, social support provided by colleagues, their own occupational self-efficacy, resilience, job crafting and readiness for change. The data is unique as it was collected in a specific situation during the pandemic, when the work of employees was affected by security measures and lockdown introduced by governments in countries where they worked.

The method for the analysis of vanadium in hexagonal mesoporous silica (V-HMS) catalysts using Laser Induced Breakdown Spectrometry (LIBS) was suggested. Commercially available LIBS spectrometer was calibrated with the aid of authentic V-HMS samples previously analyzed by ICP OES after microwave digestion. Deposition of the sample on the surface of adhesive tape was adopted as a sample preparation method. Strong matrix effect connected with the catalyst preparation technique (1st vanadium added in the process of HMS synthesis, 2nd already synthesised silica matrix was impregnated by vanadium) was observed. The concentration range of V in the set of nine calibration standards was 1.3-4.5% (w/w). Limit of detection was 0.13% (w/w) and it was calculated as a triple standard deviation from five replicated determinations of vanadium in the real sample with a very low vanadium concentration. Comparable results of LIBS and ED XRF were obtained if the same set of standards was used for calibration of both methods and vanadium was measured in the same type of real samples. LIBS calibration constructed using V-HMS-impregnated samples failed for measuring of V-HMS-synthesized samples. LIBS measurements seem to be strongly influenced with different chemical forms of vanadium in impregnated and synthesised samples. The combination of LIBS and ED XRF is able to provide new information about measured samples (in our case for example about procedure of catalyst preparation).
