Convalescents' Reports on COVID-19 Experience-A Qualitative Study.

Background: The dynamic character of the COVID-19 pandemic and its social consequences caused several medical and societal issues and dilemmas. The aim of our qualitative research was to capture and analyze attitudes and beliefs of convalescents who experienced mild symptoms of COVID-19 in the first wave of the pandemic and decided to donate their plasma for therapeutic purposes.

Material And Methods: The article presents results of qualitative research conducted on the basis of grounded theory (GT) methodology.

[Expert consensus on the usefulness of natriuretic peptides in heart failure.].

Heart failure (HF) has becoming an increasing clinical and social problem worldwide and despite modern therapy the syndrome still imposes high burden on healthcare systems. In contrast to western countries, the diagnosis of HF in Poland is established later, at more advanced stage of the disease, thus leaving less time for modern therapy and more frequently requiring hospitalisation. As a result, the alarmingly high proportion of patients with HF is treated in hospitals in Poland.

Polish Code of Ethics of a Medical Laboratory Specialist.

Along with the development of medicine, increasingly significant role has been played by the laboratory diagnostics. For over ten years the profession of the medical laboratory specialist has been regarded in Poland as the autonomous medical profession and has enjoyed a status of one of public trust. The process of education of medical laboratory specialists consists of a five-year degree in laboratory medicine, offered at Medical Universities, and of a five-year Vocational Specialization in one of the fields of laboratory medicine such as clinical biochemistry, medical microbiology, medical laboratory toxicology, medical laboratory cytomorphology and medical laboratory transfusiology.

Methodological recommendations for the diagnostics of EGFR gene mutations and ALK gene rearrangement in the selection of non-small-cell lung cancer patients to molecularly targeted therapies.

Testing for EGFR gene mutations and ALK gene rearrangement is routinely used in advanced non-small-cell lung cancer for adequate patient selection to molecularly targeted therapies. We present Polish methodological recommendations for molecular analysis of EGFR and ALK genetic abnormalities. Recommendations specify clinical indications for testing, sample types and handling, as well as requirements for laboratories performing molecular diagnostics.

[Analysis of norovirus and rotavirus infections of patients hospitalized in the General Specialist Hospital in Lublin. Retrospective studies].

Unlabelled: INDRODUCTION: Recent years have brought reports about increasing role of the viruses among the pathogens causing gastro-intestinal acute infections. Among them norovirus and rotavirus dominate. Rotavirus infections are the major reason of nosocomial infections in pediatric wards, and norovirus are the most common factors ofepidemiological gastrointestinal infections among adults.

Recommendations for the diagnosis of human papilloma virus (HPV) high and low risk in the prevention and treatment of diseases of the oral cavity, pharynx and larynx. Guide of experts PTORL and KIDL.

The role of human papilloma viruses (HPV) in malignant and nonmalignant ENT diseases and the corresponding epidemiological burden has been widely described. International head and neck oncology community discussed growing evidence that oral HPV infection contributes to the risk of oro-pharyngeal carcinoma (OPC) and recommended HPV testing as a part of the work up for patients with OPC. Polish Society of ENT Head Neck Surgery and National Chamber of Laboratory Diagnosticians have worked together to define the minimum requirements for assigning a diagnosis of HPV-related conditions and testing strategy that include HPV specific tests in our country.

[Chronic blepharitis caused by mite Demodex folliculorum].

Two cases of the very long term observation and clinical findings of chronic blepharitis caused by mite Demodex folliculorum are presented. Both patients were treated for over ten years for inflammation of the margin of the eyelid with antibiotics and steroids administered locally. A significant thickening of the blood vessels in the eyelid and numerous cylindrical cuffs of dry discharge around the base of the eyelashes persuaded us to carry out microbiological tests on the suspect eyelashes.

Antimicrobial susceptibility of aerobic microorganisms isolated from intraabdominal infections in pediatric patients in Poland.

Background: Growing resistance to antibiotics among both community-acquired and hospital pathogens is making the treatment of most infections increasingly difficult. Therefore, the aim of our multi-center study was to determine the antimicrobial susceptibility of the most frequent aerobic microorganisms isolated from children with intraabdominal infections.

Material/methods: Bacterial pathogens were isolated from 256 consecutive patients treated in five large specialized hospitals in Poland from January 2001 to February 2002.

Microbial quality of water in dental unit reservoirs.

Microbial quality of water in a dental unit is of considerable importance since patients and dental staff are regularly exposed to water and aerosol generated by the unit. Water delivered to a dental unit by the so-called independent water system is the water coming from a reservoir which, at the same time, is an initial part of dental unit waterlines (DUWL). Thus, microbiological quality of this water is extremely important for the quality of water flowing from dental handpieces.
