Respiratory Symptoms among Adolescents in Poland: A Study on Cigarette Smokers, E-Cigarette Users, and Dual Users.

In recent years, the prevalence of tobacco and electronic cigarette (e-cigarette) use among adolescents has raised significant public health concerns worldwide. This study aimed to investigate respiratory symptoms among Polish adolescents. We conducted an online survey among Polish school students from all provinces, collecting data over two months in spring 2021.

Effects of subtalar arthroereisis in children, assessed on the basis of quality-of-life questionnaires.

Introduction And Objective: Subtalar arthroereisis is a procedure commonly performed in children with flat feet. The procedure is performed when conservative treatment did not have the desired effect,or when the patient's abnormal symptoms are very severe and make it difficult for them to function normally in daily life. The aim of this study was to assess whether subtalar arthroereisis and physiotherapy improve the quality of life among children with flat feet.

Toxic Streptococcal Infection in Children: Report on Two Cases with Uncharacteristic Course of Scarlet Fever.

Introduction: Scarlet fever is usually a mild childhood disease caused by type A . This disease is spread by droplets, mainly through direct contact with an infected person or the objects they have used. In pediatrics, these are significant risk factors for the transmission of infectious diseases.

The influence of maternal vaginal flora on the intestinal colonization in newborns and 3-month-old infants.

Aim: The role of maternal vaginal bacteria on the colonization of neonatal gut is still a matter of discussion. Our aim was to estimate the role of maternal vaginal flora on the development of intestinal flora in neonates and 3-month-old infants.

Methods: Seventy-nine maternal-neonatal pairs were included in the study.

Chlamydia trachomatis infection in women with lichen sclerosus vulvae and vulvar cancer.

Objective: Chronic infections in the urogenital area often precede or coexist with vulvar cancer. A strong connection between some tumours and the-appearance of Chlamydia trachomatis infection has been observed, but there is little information concerning a connection of that infection with vulvar cancer and lichen sclerosus vulvae (LS). The aim of this study was the analysis of frequency of antigens appearance and antibodies of IgM and IgG Chlamydia trachomatis in patients with vulvar cancer and LS and we wanted to find the correlation between Chlamydia trachomatis infection and vulvar cancer and LS.

Effectiveness of photodynamic therapy in the treatment of lichen sclerosus: cell changes in immunohistochemistry.

Background: Vulvar lichen sclerosus (LS) affects primarily women at postmenopausal age and its background remains unknown. One of the treatment modalities is photodynamic therapy (PDT). The aim was to investigate the efficacy of PDT in women with LS and the analysis of protein expression before and after PDT.

Prenatal priming of cord blood T lymphocytes by microbiota in the maternal vagina.

Problem: In the vagina of women at the reproductive age, more than 170 strains of bacteria and yeasts are found. The effect of vaginal flora on neonatal T cells is yet to be investigated.

Method Of Study: We analyzed CD45RA and CD45RO expression on neonatal CD4+ T cells and cytokine production in CBMC cultures (interferon-gamma (IFN-gamma ), interleukin-4 (IL-4) and IL-12) related to vaginal bacteria isolated from a maternal vagina.

CD30 on stimulated CD4+ T lymphocytes in newborns regarding atopic heredity.

CD30 was initially described as Ki-1 Ag on Reed-Sternberg cells of Hodgkin's lymphoma and its and CD30L(+) expression on T cells in placenta were equally frequent in the atopic and non-atopic women. In this article we present a study of CD30 mean fluorescence intensity (MFI) on CB T CD4(+) cells. We tested the hypothesis that in newborns with atopy family history there is a changed CB T cells response after antigen stimulation comparing with those without atopy family history.
