Component-resolved diagnostics enables the detection of allergen-specific immunoglobulins E (asIgE) to house dust mite (HDM) proteins, which may help clinicians to face the difficulties in diagnostics of HDM allergy. Currently, almost 40 proteins of Dermatophagoides species, that are able to bind asIgE, have been identified, and this number will certainly increase. The association between sensitisation to particular molecules and allergy symptoms is extensively studied. This investigation enables us to identify HDM molecules that promote respiratory, skin, or food allergies, and it could help us predict the possible course of allergic diseases. The individual repertoire of asIgE improves our understanding of immunological response, which underlies allergy symptoms, and helps to form individual therapeutic regimens. This review provides clinicians with information on Dermatophagoides pteronyssinus proteins available in commercial arrays, and their role in the diagnostics and management of HDM allergy., Competing Interests: E.M. is employee of EMMA MDT Sp z o.o. company.

Currently, hybrid closed loop (HCL) systems represent the most advantageous therapeutic option for people with diabetes requiring intensive insulin therapy. They make it possible to achieve optimal metabolic control of the disease in any age group while improving the quality of life of children and adolescents with diabetes and their families. Therefore, we present recommendations for the use of HCL systems in children and adolescents focusing on systems currently available in Poland. These systems should be the first choice in terms of method of insulin therapy in the paediatric population. They can be implemented at any stage of diabetes management. These recommendations are based on scientific evidence and experts' experience. They include principles for the initiation, optimisation, and ongoing management of HCL therapy, as well as the required HCL-related education.

Introduction: Colorectal cancer have been one of the most common malignant neoplasm in the world. In most patients with this cancer, we can observe both redox homeostasis and nutritional disorders., Aim: To assess the occurrence of oxidative stress in patients with colorectal cancer and its severity depending on the nutritional status of patients., Material and Methods: The study group consisted of 50 patients with colorectal cancer. In the control group, samples were obtained from 40 healthy subjects. Basal metabolic index and nutrition risk screening (NRS) 2002 scale was completed. The total antioxidant capacity (TAC), total oxidant status (TOS), malondialdehyde (MDA) were determined yielding the oxidative stress index (OSI) determined by the TOS/TAC ratio and TAC/MDA ratio., Results: There were statistically significant differences ( p < 0.05) in the levels of not only TAC, TOS, OSI, but also MDA and TAC/MDA. In healthy patients, the TAC and TAC/MDA level was significantly higher ( p < 0.05) compared to the cancer patients, while the TOS, OSI and MDA level was significantly lower ( p < 0.05). In patients with BMI < 24.9 kg/m 2 , the level of TAC was significantly higher and the level of TOS was significantly lower ( p < 0.05) compared to patients with BMI > 24.9 kg/m 2 . In patients with features of malnutrition according to the NRS 2002 scale, TOS and OSI were statistically significantly higher ( p < 0.05)., Conclusions: Neoplastic disease, such as colorectal cancer, precipitates an increase in oxidative stress. Concurrently, the nutritional status of patients, especially malnutrition, further intensifies this process., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Termedia.)

Numerous physiological processes occurring in the digestive system are subject to circadian rhythms, which are regulated by the endogenous biological clock. The motor activity of the small intestine, large intestine, and rectum operates in a 24-hour system, with significant differences between day and night periods. It is primarily correlated with the time of meals, hormone secretion rhythms, and other activities undertaken by the organism. In recent years, numerous scientific reports have emerged about the fundamental role of circadian rhythms in the proper functioning of the gut microbiota. In addition, the microbiota and its metabolites also influence the host's daily cycles, which affects the overall state of their organism. The aim of this review is to outline the mechanisms of action and interactions between biological rhythms, gut motility, and the functioning of the gut microbiota., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Termedia.)

Introduction: Over the past three decades, almost every type of abdominal surgery has been performed and refined using the laparoscopic technique. Surgeons are applying it for more procedures, which not so long ago were performed only in the classical way. The position of laparoscopic surgery is therefore well established, and in many operations it is currently the recommended and dominant method., Aim: The aim of the preparation of these guidelines was to concisely summarize the current knowledge on laparoscopy in acute abdominal diseases for the purposes of the continuous training of surgeons and to create a reference for opinions., Material and Methods: The development of these recommendations is based on a review of the available literature from the PubMed, Medline, EMBASE and Cochrane Library databases from 1985 to 2022, with particular emphasis on systematic reviews and clinical recommendations of recognized scientific societies. The recommendations were formulated in a directive form and evaluated by a group of experts using the Delphi method., Results and Conclusions: There are 63 recommendations divided into 12 sections: diagnostic laparoscopy, perforated ulcer, acute pancreatitis, incarcerated hernia, acute cholecystitis, acute appendicitis, acute mesenteric ischemia, abdominal trauma, bowel obstruction, diverticulitis, laparoscopy in pregnancy, and postoperative complications requiring emergency surgery. Each recommendation was supported by scientific evidence and supplemented with expert comments. The guidelines were created on the initiative of the Videosurgery Chapter of the Association of Polish Surgeons and are recommended by the national consultant in the field of general surgery. The second part of the guidelines covers sections 6 to12 and the following challenges for surgical practice: acute appendicitis, acute mesenteric ischemia, abdominal injuries, bowel obstruction, diverticulitis, laparoscopy in pregnancy and postoperative complications requiring a reoperation., (Copyright: © 2023 Fundacja Videochirurgii.)

Introduction: The long-term observation of the incidence of IgE-dependent sensitization to environmental allergens (food and airborne allergens) of a specific population plays an important role in epidemiological studies., Aim: Retrospective, comparative assessment of IgE-dependent sensitization to food and airborne allergens in the group of patients from the north-eastern region of Poland, in selected years (1998, 2003, 2008, 2012). Long-term assessment of the incidence of IgE-dependent sensitization depending on the age of the patients (1998-2012)., Material and Methods: A group of 6577 children and adolescents aged up to 18 years with a suspicion of an allergic process, diagnosed in 1998-2012. Skin prick tests (SPT) with selected food allergens and airborne allergens were used to evaluate the sensitization process of patients., Results: A significant increase in the percentage of patients sensitized was found, comparing 1998 vs. 2012: to at least one allergen (35.3% vs. 40.4%); only to food allergens (5.1% vs. 13.1%), and to at least one food allergen (10.5% vs. 20.1%). There were no significant changes in the percentage of children and adolescents sensitized to airborne allergens (22.7% vs. 20.3%). The percentage of sensitization to at least one allergen was lowest in 2-year-old children (30.2%), and highest in 15-year-old children (46.8%). The percentage of patients sensitized to airborne allergens increased statistically significantly with their age: 6.3% in infants, 43.7% in adolescents., Conclusions: During the 14-year-period of the study the authors observed an upward trend in the frequency of sensitization to food allergens. The frequency of sensitization to airborne allergens was similar at the beginning and the completion of the study., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2023 Termedia Sp. z o. o.)

Fabry disease is a rare, X-linked metabolic error caused by various mutations in the α-galactosidase A gene, which results in the accumulation of glycosphingolipids. Gastrointestinal symptoms are quite common in affected patients; therefore, it is important for gastroenterologists to keep it in mind as a differential diagnosis for especially challenging patients. The following review provides concise information on epidemiology and genetics, signs, and symptoms of the disease, focusing on the gastrointestinal (GI) tract, providing a brief overview of the diagnostic process and the available treatment, both disease specific and supportive, again with a focus on alleviation of gastrointestinal symptoms., Competing Interests: ARR and TH have received speaker honoraria from Sanofi and Takeda., (Copyright © 2023 Termedia.)

SARS-CoV-2 infection manifests mainly by involving the respiratory system. Due to the presence of abdominal symptoms, the digestive system is clearly involved in the expression, transmission, and possible pathogenesis of COVID-19. There are many theories regarding the development of abdominal symptoms, including angiotensin 2 receptor, cytokine storm, and disturbances of the intestinal microbiome. This paper provides an overview of the most important meta-analyses and publications on gastrointestinal symptoms and the gut microbiome in COVID-19., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Termedia.)

Introduction: A widely accepted treat-to-target strategy for rheumatoid arthritis (RA) requires the patient's perspective in making treatment decisions. However, data on treatment preferences and expectations of Polish patients with RA are scarce. The aim of the study was to determine the satisfaction with treatment and the nature of therapeutic preferences and expectations of Polish patients with moderate to severe RA., Material and Methods: Fifty-two adult Polish patients with moderately to highly active RA were asked to complete patient-reported outcomes and patient-provided information questionnaires. Additionally, patient sociodemographic and clinical data and information on patient current and planned treatment strategies were collected., Results: The mean global assessment of patient satisfaction with treatment was 64.1 ±24.6, below the level of indicating satisfaction. Rheumatoid arthritis negatively impacted patients' lives, resulting in a 37.8% impairment of work efficiency and 45% impairment of total activity. Primary treatment expectations for patients were lasting relief of RA symptoms, reduced pain and swelling in joints, increased flexibility of joints, and general improvement of arthritis. The most acceptable potential side effect was weight gain and the least acceptable were increases in the risk of cardiovascular disease, infection, and malignancies. The rapid onset of the drug effect (up to 1 week) was a preference of 48.1% of patients. Access to internet health resources was important for 44.2% of patients, but the median total eHealth literacy score in the study population was 24.0 (interquartile range: 20.5-28.0, range 8-37), which means low digital health literacy (DHL)., Conclusions: Understanding these treatment preferences and expectations of patients with RA is essential for clinical practitioners to facilitate shared treatment decision-making. Digital health literacy data suggest the need of further improvement., Competing Interests: Marcin Stajszczyk received consultation and/or speaking fees from Abbvie, Astra Zeneca, Boeringer Ingelheim, Celgene, Eli Lilly, Janssen, Merc Sharp & Dohme, Novartis, Pfizer, Sandoz, Swedish Orphan Biovitrum, UCB.

Introduction: Around 200,000 new cases of pancreatic cancer are diagnosed yearly worldwide. It is the fourth most common cause of cancer deaths. Pancreatic cancer has a high mortality rate due to unspecific symptoms being responsible for late diagnosis., Aim: In this study, the authors analysed selected nutritional parameters and the severity of anaemia in patients diagnosed with pancreatic head cancer., Material and Methods: Data were collected upon admission to the 2 nd Clinical Department of General, Gastrointestinal, and Oncological Surgery in the University Clinical Hospital in Bialystok, Poland and retrospectively with the help of correctly collected anamnesis., Results: It has been shown that most patients with pancreatic cancer are malnourished at the time of diagnosis. Body mass index (BMI) is the least valuable parameter primarily. Weight loss has been determined to be the most accurate predictor of the patient's metabolic status, although it should never be the only parameter. Although these factors do not suggest an inflammatory process, serum protein levels and albumin concentration should be considered., Conclusions: When assessing the nutritional status of patients with pancreatic cancer, many predictive factors should be considered. BMI seems to be the least accurate parameter for assessing nutritional status in patients diagnosed with cancer. However, when combined with weight loss and serum albumin levels, it can be quite useful as a prognostic factor., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Termedia.)

Helicobacter pylori remains a major health problem worldwide, causing considerable morbidity and mortality due to peptic ulcer disease and gastric cancer. These guidelines constitute an update of the previous "Recommendations on the diagnosis and management of Helicobacter pylori infection" issued in 2014. They have been developed by a Task Force organized by the Governing Board of the Polish Society of Gastroenterology. They discuss, with particular emphasis on new scientific data covering papers published since 2014: the epidemiology, clinical presentation, diagnostic principles and criteria for the diagnosis, and recommendations for the treatment of H. pylori infection. The guidelines in particular determine which patients need to be tested and treated for infection. The Task Force also discussed recommended treatment algorithms. Accordingly, a combination of available evidence and consensus-based expert opinion were used to develop these best practice advice statements. It is worth noting that guidelines are not mandatory to implement but they offer advice for pragmatic, relevant and achievable diagnostic and treatment pathways based on established key treatment principles and using local knowledge and available resources to guide regional practice., Competing Interests: Professor PhD, MD Anita Gąsiorowska: a speaker for Urgo Polfa Lodz.

Introduction: It is known that the virus SARS-CoV-2 can attack the gastrointestinal (GI) tract and induce gastroenteritis. This can trigger a wide variety of disorders of gut-brain interaction (DGBIs) or functional gastrointestinal disorders (FGIDs), including post-infectious dyspepsia, which remains underestimated., Aim: To estimate the prevalence of dyspeptic symptoms following COVID-19, immediately after discharge and 3, 6, and 9 months after hospitalization., Material and Methods: A prospective, single-centre evaluation of questions regarding functional dyspepsia (FD) as assessed by the Gastroduodenal Module of ROME IV Diagnostic Questionnaire for Adult FGIDs among 320 patients who had had COVID-19., Results: The FD ROME IV criteria were met at the respective time-points by 0.0% (0), 4.8% (12), 3.2% (8), and 3.2% (8) of cases. However, the presence of GI symptoms that suggested FD but did not meet the timeframe ROME IV criteria for FD were found in 9.6% (24), 23.5% (59), 20.7% (52), and 20.7% (52) of cases, respectively., Conclusions: The presence and persistence of gastrointestinal dyspeptic symptoms following COVID-19 is a significant problem. The timeframe of the Rome IV criteria may underestimate the number of patients with persistent dyspeptic symptoms following COVID-19 disease., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Termedia.)

Introduction: Melanocytes show antigen expressions characteristic for the immune response effector cells, and the immune reactions in the skin, especially those with inflammation background, significantly affect the function of melanocytes. Among the cytokines produced by keratinocytes, the stem cell factor (SCF) plays a leading role in stimulating melanogenesis., Aim: To compare the expression level of stem cell factor (mSCF, pSCF) and the c-Kit receptor in the centre of the vitiligo patch and in the area of healthy skin adjacent to the vitiligo patch., Material and Methods: The research material consisted of skin samples from a vitiligo lesion and from non-lesional skin adjacent to the vitiligo patch. Real Time PCR analysis (Applied Biosystems 7900HT) was performed to determine the expression level of the studied genes., Results: The studies showed a statistically significant increase in the amount of mSCF within the vitiligo patch compared to both healthy skin of patients with vitiligo and controls. In patients with vitiligo, c-Kit receptor expression was significantly decreased in the area of the lesional skin compared to the healthy skin of the same patient and the skin of the control group., Conclusions: The membrane-bound form of the SCF is overexpressed within the vitiligo skin, which may indicate the participation of mSCF in the stimulation of melanogenesis in response to melanocyte damage. Decreased expression of C-Kit receptor by melanocytes in the vitiligo patch disrupts the ligand-receptor interaction and may therefore be related to melanocytes dysfunction and/or loss., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 Termedia Sp. z o. o.)

Introduction: Revisional surgery is more technically challenging and associated with increased morbidity and mortality. Nevertheless, the frequency of revisional bariatric surgery (RBS) is increasing. Therefore, investigating this group of patients appears to be currently valid., Aim: The objective of this multicenter study was to collect, systematize and present the available data on RBS after surgical treatment of morbid obesity among Polish patients., Material and Methods: This multicenter study included a retrospective analysis of a prospectively maintained database. Outcomes included an analysis of the indications for RBS, the type of surgery most frequently chosen as RBS and the course of the perioperative period of treatment among patients undergoing RBS., Results: The group consisted of 799 patients (624 (78.1%) women, 175 (21.9%) men). The mean age was 38.96 ±9.72 years. Recurrence of obesity was the most common indication for RBS. The most frequently performed RBS procedures were one anastomosis gastric bypass (OAGB) - 294 (36.8%) patients, Roux-en-Y gastric bypass (RYGB) - 289 (36.17%) patients and sleeve gastrectomy (SG) - 172 (21.52%) patients. After primary surgery 63.58% of patients achieved sufficient weight loss, but after RBS only 38.87%. Complications were noted in 222 (27.78%) cases after RBS with GERD being the most common - 117 (14.64%) patients., Conclusions: RBS most often concerns patients after SG. The main indication for RBS is weight regain. OAGB and RYGB were the two most frequently chosen types of RBS. Secondary operations lead to further weight reduction. However, RBS are associated with a significant risk of complications., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 Fundacja Videochirurgii.)

Recently, a dramatic increase in the average life expectancy has been noted, regarded as the one of the greatest achievements of the last decades, but in consequence osteoporosis affects millions of people all over the world. Currently osteoporosis is defined as a skeletal disorder characterized by compromised bone strength which leads to an increased risk of fractures. The most commonly used tool to evaluate the 10-year risk of fractures is the fracture risk assessment tool validated in many independent cohorts. Osteoporosis itself has no symptoms, but fractures are common symptoms of osteoporosis which can result in disability and mortality. Hence, osteoporosis is called a silent epidemic as well as a silent killer. The best way to assess patients with osteoporosis is by using the most widely employed techniques - dual-energy X-ray absorptiometry or quantitative computed tomography. There are a lot of precisely documented risk factors of osteoporosis - e.g. cigarette smoking, alcohol use, getting little or no exercise, being small-framed or thin, a diet low in foods containing calcium and vitamin D - and their limitation or elimination is the best way for prophylactics of this dangerous disease. Some other risk factors such as age and sex of patients should not be omitted in the decision making process. In the literature there are numerous therapeutic proposals and different guidelines. In this review we present the recent advances in the prophylactics and treatment of osteoporosis., Competing Interests: The authors report no conflict of interest., (Copyright © 2022 Termedia.)

Introduction: During the COVID-19 pandemic health care systems worldwide rapidly implemented telemedicine solutions in order to avoid spreading the coronavirus among doctors and patients., Aim: To analyse the knowledge, usage, and attitude towards telemedicine among patients, dermatologists, and other doctors during the COVID-19 pandemic., Material and Methods: An original anonymous online survey was carried between 22 September 2020 and 29 December 2020 in Poland among 121 patients, 63 dermatologists, and 50 doctors of other specialties. Statistical analysis was performed using the χ 2 test, and a statistically significant difference was considered at p < 0.05., Results: In the analysed period in the patient group 58.7% suffered from a skin disease and 79.3% used telemedicine during the COVID-19 pandemic, 54.5% of all respondents viewed teleconsultations unfavourably, and 96.6% of dermatologists and 88% of other doctors had to schedule in office visit or ask for additional pictures because of an unclear clinical picture during teleconsultation. There was a statistical significance between dermatologists and other specialty doctors regarding telemedicine's ability to replace office visits, its usefulness in the elderly, and the duration of the teleconsultation compared to a traditional in-person visit (all p < 0.05)., Conclusions: The results showed that in many cases issues raised during teleconsultations could not have been solved using telemedicine. The results obtained highlight the unfavourable perception of telehealth. Overall, telemedicine is a safe and useful tool for communicating with patients, increasing access to medical care, but it needs to be evaluated in the context of potential limitations and optimizing the patients' experience., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 Termedia Sp. z o. o.)

Introduction: Omentin and vaspin are considered to have beneficial effects preventing the development of metabolic disorders which are common comorbidities in psoriasis., Aim: To evaluate the serum level of these adipokines in psoriatic patients and elucidate possible associations with disease activity, metabolic or inflammatory parameters and systemic treatment., Material and Methods: Thirty-three patients with active plaque-type psoriasis and 11 healthy controls participated in the study. Blood samples were collected before and after 3 months of treatment with acitretin or methotrexate., Results: Serum vaspin concentration in psoriatic patients was significantly lower than in the control group ( p < 0.05). No correlation between adipokines and severity of disease evaluated with PASI was found. However, median vaspin levels decreased with the severity of skin lesions and the omentin level was higher in patients with severe disease versus those with moderate form ( p < 0.05). The vaspin level correlated with BMI of psoriatic patients ( p < 0.05), with cholesterol and triglycerides levels ( p = 0.054, p = 0.049, respectively). No significant effect of systemic treatment on omentin levels was found. Regarding vaspin, we observed an upward trend in its concentration after treatment., Conclusions: Omentin and vaspin may play a modulating role in the systemic inflammation present in psoriasis and thus may contribute to the development of metabolic complications., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 Termedia Sp. z o. o.)

Introduction: Data regarding the duration of dual antiplatelet therapy (DAPT) in patients with drug-eluting stent restenosis (DES-ISR) treated with percutaneous coronary intervention (PCI) and drug-eluting balloons (DEB) or DES are not unambiguous., Aim: To evaluate the relationship between long-term outcomes and the length of DAPT in patients treated with PCI due to DES-ISR with DEB or DES., Material and Methods: Overall, a total of 1,367 consecutive patients with DES-ISR, who underwent PCI with DEB or DES between 2008 and 2019 entered the study. The mean length of the follow-up was 1,298.7 ±794 days. We assessed study endpoints according to the duration of DAPT (≤ 3 vs. > 3 and ≤ 6 vs. > 6 months) before and after propensity score matching (PSM): stroke, target lesion revascularisation (TLR), target vessel revascularisation (TVR), myocardial infarction (MI), death and device oriented composite endpoints (DOCE). Kaplan-Meier estimates were created to differentiate long-term outcomes., Results: Pairwise contrast analysis considering type of PCI (DES vs. DEB) and duration of DAPT (≤ 6 vs. > 6 months) before PSM revealed superiority of DES + DAPT > 6 months vs. DEB + DAPT > 6 months for DOCE ( p < 0.001), TVR ( p = 0.02) and TLR ( p = 0.01). Also, DES + DAPT ≤ 6 months was found to be superior compared to DEB + DAPT ≤ 6 months for DOCE ( p < 0.001), TVR ( p = 0.02) and TLR ( p = 0.01). Kaplan-Meier estimate analysis confirmed that DAPT > 6 months is related to a higher stroke rate ( p = 0.01) when compared to ≤ 6 months., Conclusions: Treatment with DAPT in patients with DES-ISR is related to better long-term outcomes in the case of PCI with DES than DEB. DAPT > 6 months is related to the greater rate of strokes, independently of the type of treatment (DES and DEB) than DAPT ≤ 6 months., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2022 Termedia Sp. z o. o.)

Children and adolescents are particularly vulnerable to skin damage caused by ultraviolet radiation and require intensified photoprotection. Benzophenone-3 (BP-3) belongs to the organic sunscreens, which are widely used in personal care and cosmetic products. However, the impact of BP-3 on human health requires a careful assessment. This review focuses on potentially harmful effect of this compound in relation to the developing organism. Studies show that BP-3, after topical application, can penetrate into bloodstream, blood-brain barrier and blood-placental barrier and may induce the reproductive toxicity and abnormal development of the foetus, endocrine system disruption and neurotoxicity in experimental animal models. So far, human studies have been scarce and controversial, therefore the cosmetics containing BP-3 should be carefully used by the pregnant women, children and adolescents., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Termedia.)

Introduction: Drug-induced diabetes mellitus (DIDM) could be defined as a heterogenic group of diabetes caused by pharmacotherapy. The DIDM is considered to be reversible after discontinuation of diabetogenic treatment, but there is a risk of persistence, which is related to the duration of treatment, prescribed medication, and body mass index., Case Presentation: A 13-year-old boy treated for nephrotic syndrome with the use of tacrolimus and prednisone was diagnosed with diabetes during a check-up visit. On admission, he showed a cushingoid appearance and complained of dry mouth, which was not accompanied by polyuria or polydipsia. Blood tests showed elevated levels of glucose, and glycated A1c fraction of haemoglobin (HbA1c = 10.2%). Pancreatic islet autoantibodies were negative. The fasting and postprandial C-peptide levels were within the normal range. Diabetic ketoacidosis was excluded. Intensive insulin therapy was initially introduced; the daily dose of insulin per kilogram was low (TDD/kg = 0.31 U/kg). Those findings prompted us to consider diabetes mellitus type 2 or DIDM. Moreover, the TDD/kg and HbA1c additionally decreased after the steroid withdrawal. Because he was constantly on diabetogenic therapy and experienced periodical hyperglycaemia, DIDM could not be excluded. Therefore, our patient remained on insulin treatment., Conclusions: DIDM in children is challenging for all specialists. Diabetologists need to remember about this rare subtype of diabetes, and other specialist should perform screening on their patients who are at risk of DIDM. There is a great need for guidelines that would provide a standardized approach for diagnosing and treating DIDM in the paediatric population.

Objectives: Rheumatoid arthritis (RA) is a multisystem, chronic, T-cell-mediated disease in which immunological abnormalities result in symmetrical small joint inflammation, articular destruction due to synovitis, and extra-articular organ involvement. An important role in the pathogenesis of RA is attributed to a combination of genetic factors and environmental triggers. Literature data on the utility of circulating IL-1β, IL-6, IFN-γ, and sP-selectin concentration evaluation depending on the activity and advancement of RA seems to be inconclusive. The aim was a case-control study evaluating IL-1β, IL-6, IFN-γ, and sP-selectin concentrations in 77 RA patients dependent on the Steinbrocker classification as well as the disease activity score with examination of 28 joints (DAS28), and compared to 30 control subjects., Material and Methods: Serum IL-1β, IL-6, IFN-γ, and sP-selectin concentrations were measured using ELISA kits., Results: The concentrations of all molecules tested, except for IL-1β, were significantly different from the control group. Univariate logistic regression analysis indicated that their levels significantly influenced the likelihood of RA diagnosis. Differences between IL-1β, IL-6, IFN-γ, and sP-selectin concentrations dependent on the disease activity assessed on the basis of the DAS28 score, as well as the severity of the disease assessed based on the Steinbrocker classification, were not observed. IL-6 positively correlated with the DAS28 score., Conclusions: Among the tested molecules, only IL-6 positively correlated with the DAS28 score. Thus, we postulate that next to C-reactive protein and the erythrocyte sedimentation rate, also IL-6 could be clinically relevant and possibly reflects RA activity. Because recently the IL-6 concentration can be determined in applied in vitro diagnostic tests, it presents us with the possibility to test this protein as a marker of RA activity in routine laboratory practice., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Narodowy Instytut Geriatrii, Reumatologii i Rehabilitacji w Warszawie.)

Glycogen storage disease type 1b (GSD 1b) is an inherited metabolic defect caused by a deficiency of microsomal glucose-6-phosphate (G6P) transport protein across the endoplasmic reticulum membrane. Patients with GSD 1b have hypoglycemia episodes, lactate acidosis, hypertriglyceridemia, hypercholesterolemia, hyperuricemia, neutropenia and in imaging studies hepatomegaly and/or nephromegaly. The primary goals of treatment are to maintain proper blood glucose levels and to increase the number of properly functioning neutrophils. The aim of the study was a retrospective analysis of the clinical picture and treatment results of pediatric patients with type 1b glycogen storage disease from Poland. The study included 13 patients from 3 clinical centers, with a median age at diagnosis as 5 months. In 11/13 patients, the diagnosis was confirmed by molecular test, by the presence of pathogenic variants on both alleles of the SLC37A4 gene. Ten out of 13 patients developed the first symptoms in the form of severe infection (sepsis and/or pneumonia) already in the neonatal-infant period. A hypoglycemia episode was observed before diagnosis in 8/13 patients, of which 4/8 patients presented symptoms in the form of generalized relaxation and/or seizures. Two patients developed hypertension, and 4/13 required long-term treatment of inflammatory bowel disease.

Introduction: Gastrointestinal (GI) symptoms can be considered as a manifestation of coronavirus disease 2019 (COVID-19)., Aim: Our study analysed GI symptoms depending on their occurrence, and their possible causes and impact on the course of COVID-19., Material and Methods: A retrospective, single-centre assessment of the frequency, risk factors, and impact of GI symptoms in 441 patients with COVID-19., Results: A statistically significant reduction in the length of stay (LOS) (15 days vs. 17 days; p = 0.04), intensive care unit admission (ICU) (16.9% vs. 26.8%; p = 0.02), and need for mechanical ventilation (14.1% vs. 23.4%; p = 0.02) in the group who had experienced GI symptoms before hospitalization was noticed. For comparison, patients who developed GI symptoms during hospitalization had statistically significantly longer LOS (21 days vs. 15 days; p = 0.0001), were more frequently admitted to the ICU (38.1% vs. 18.6%; p = 0.0003), and had a higher need for mechanical ventilation (32.7% vs. 16.2%; p < 0.001). Risk factors for GI symptoms during hospitalization in COVID-19 patients included age, Clostridioides difficile infection, and receiving certain treatment (antibiotics and lopinavir + ritonavir)., Conclusions: The GI symptoms that developed before admission to hospital correlated with reduced severity of the course of COVID-19. However, in the group of patients who developed GI symptoms during hospitalization, attention should be paid to concomitant treatment. The use of antibiotics should be limited because they are associated with the deterioration of the course of COVID-19; one of the reasons might be changes in the intestinal microbiome., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Termedia.)

Aim: The aim of the study was to assess the effectiveness of a patented preparation of sodium butyrate in the triglyceride matrix at reducing clinical symptoms and improving quality of life in patients with irritable bowel syndrome (IBS)., Material and Methods: In this prospective multicenter clinical trial, we observed a total of 3000 non-hospitalized patients with confirmed IBS who were treated with sodium butyrate in a triglyceride matrix at a dosage of 150 mg twice a day for 12 weeks. The primary outcome was to evaluate the efficacy of sodium butyrate at reducing the severity of clinical symptoms and improving quality of life in patients with IBS., Results: A total of 2990 complete surveys were collected. A statistically significant improvement in severity of abdominal pain was noticed ( p < 0.001). Moreover, flatulence, diarrhea, constipation, urgent pressure for bowel movements, nausea, and vomiting decreased significantly ( p < 0.001). Most of the respondents (93.90%) declared that they would continue the therapy and 88.9% would recommend using sodium butyrate to other IBS patients., Conclusions: Sodium butyrate in the triglyceride matrix, as a postbiotic substance, may be effective in relieving the symptoms of IBS by modifying the intestinal microbiota., Competing Interests: Partially sponsored by a scientific grant from Bioton., (Copyright © 2022 Termedia.)

Introduction: Despite the growing number of studies on the epidemiology of out-of-hospital cardiac arrest (OHCA) in Poland, this issue has not been sufficiently studied. Notably, there has been a lack of uniform Utstein-style data reporting., Aim: To evaluate the epidemiology of OHCA, patient characteristics, the laypeople and emergency medical service (EMS) response to cardiac arrest, and outcomes of OHCA patients, based on a prospective registry encompassing a population of 2.7 million Poles., Material and Methods: Consecutive, adult, EMS-treated OHCA cases in 2018 were analyzed. Prehospital data were collected using case report forms by EMS. Information on in-hospital procedures and outcomes was based on data from the public payer of health care services. Multivariable logistic regression analysis was performed to find independent predictors of survival to discharge., Results: A total of 1392 patients were included. Most OHCA occurred at home (74.7%). In 66.8% of OHCA cases, the cardiac arrest was witnessed by bystanders and in another 20.4% by EMS. Laypeople performed cardiopulmonary resuscitation (CPR) in 54.4% of non-EMS-witnessed events, and an automated external defibrillator (AED) was used in 4.6% of patients who received bystander CPR. Finally, 30.7% of all patients were transported to the hospital, and 9.2% survived to hospital discharge. Epinephrine administration, unwitnessed OHCA, longer response time, older age, and initial non-shockable rhythm were independently associated with lower survival to discharge., Conclusions: The prognosis of OHCA patients in Poland is poor. There is still room for improvement in increasing the prevalence of bystander CPR and AED use before EMS arrival., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2021 Termedia Sp. z o. o.)

Introduction: Krüppel-like factor 4 (KLF4) is a transcription factor of anti-inflammatory and anti-thrombotic properties not studied in psoriasis yet., Aim: To analyze the clinical value of the serum KLF4 level in psoriatics and elucidate the interplay between disease activity, metabolic or inflammatory parameters and systemic therapy., Material and Methods: The study enrolled thirty-four psoriatics and fifteen healthy subjects. Blood samples were collected before and after twelve weeks of treatment with methotrexate or acitretin. Serum KLF4 levels were measured using immune-enzymatic method., Results: Serum KLF4 levels in psoriatic patients did not statistically differ comparing to the controls ( p > 0.05). However, in severe psoriasis, KLF4 was significantly higher than in healthy ones before treatment and normalized after treatment to baseline levels of controls ( p < 0.05, p > 0.05, respectively). KLF4 positively correlated with body mass index ( p = 0.038) but not with psoriasis severity, nor inflammatory or metabolic markers. Interestingly, many pro-atherogenic parameters were shown as variables independently predicting the levels of KLF4. No significant effect of three-month systemic treatment on KLF4 was found., Conclusions: KLF4 may be a novel independent indicator of the proatherogenic risk in psoriatics, especially with a severe form or obesity., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2021 Termedia Sp. z o. o.)

Introduction: Psoriasis is a chronic inflammatory disease associated with metabolic disturbances and liver dysfunction. Both serum fatty acids (FA) and ceramides (Cer) have structural functions but also are signal molecules that could be involved in the pathogenesis of liver dysfunction., Aim: To assess the concentration of the circulating FA and Cer in correlation with the alanine aminotransferase (ALT) blood level in psoriatic patients. In addition, we have examined the relationship between ALT concentration and severity of the disease and inflammation markers., Material and Methods: Eighty-five patients with psoriasis and 32 healthy controls were enrolled in the study. Patients were divided into 2 groups according to ALT blood levels. Serum concentration of 14 FA and 14 Cer were measured by gas-liquid chromatography. The results were correlated with the Psoriasis Area and Severity Index (PASI), serum lipid profile, and inflammatory markers., Results: We observed higher PASI score ( p = 0.01) and higher C-reactive protein ( p = 0.02) concentration in the group of psoriatic patients with high ALT. Serum ALT positively correlated with saturated fatty acids (SFA) ( p = 0.01, r = 0.27) and SFA/unsaturated fatty acids (UFA) ratio ( p = 0.01, r = 0.26). ALT negatively correlated with UFA level ( p = 0.008, r = -0.28). Lignoceric ceramide positively correlated with ALT level ( r = 0.22; p = 0.045) in psoriatic patients., Conclusions: Patients with severe psoriasis are predisposed to the development of liver dysfunction. We have demonstrated disturbances of serum fatty acid and sphingolipid profile in psoriatic patients, which may trigger liver disease., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Termedia.)

Introduction: Pulmonary artery hypertension and its consequences still constitutes an underestimated clinical problem in asthma patients and its non-invasive early detection may influence proper treatment., Aim: To non-invasively examine the pulmonary artery flow parameters and right ventricular function in patients with asthma of various severity., Material and Methods: The analysis of parameters of echocardiography and first-pass and gated radionuclide angiography, and baseline examination in 31 patients with bronchial asthma and 16 healthy controls., Results: Patients with severe asthma had higher mean pulmonary artery pressure (MPAP) compared to the healthy controls. The subgroup analysis of patients who suffered from asthma in their childhood showed that individuals with severe asthma were characterized by significantly higher MPAP than those with the mild/moderate condition (19.16 ±7.51 mm Hg vs. 5.0 ±1.15 mm Hg, p = 0.025). Gated, but not first-pass, radionuclide angiography revealed that individuals with severe asthma were characterized by a lower right ventricular ejection fraction (RVEF). Further analysis of the subgroup of patients in whom the initial manifestation of dyspnoea occurred no earlier than 6 years prior to the study showed that the RVEF of individuals with severe asthma was significantly lower compared to those with mild/moderate asthma (39.8 ±4.79% vs. 51.4 ±8.65%, p = 0.019)., Conclusions: The pulmonary artery pressure in patients with severe asthma is significantly higher than in healthy individuals; in contrast, these two groups did not differ significantly in terms of the right ventricular echocardiographic characteristics. Gated radionuclide angiography, but not the first-pass technique, allowed for the detection of subtle right ventricular ejection fraction changes in asthma patients., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Termedia.)

Introduction: Seasonal allergic rhinitis (SAR) and bronchial asthma are typical manifestations of pollen-food sensitization in adults. There is limited information regarding the sensitization patterns of pollen-food allergy in children., Aim: To evaluate the prevalence of SAR in children with pollen-food sensitization and assess the impact of food allergens on nasal symptoms., Material and Methods: Forty-three children with pollen-food sensitization aged 2-14 years were evaluated for evidence of SAR. The inclusion criteria was IgE-mediated sensitization to pollen and homologous food allergens. The control group consisted of 19 children with SAR caused by pollen without sensitization to homologous food allergens., Results: Allergic rhinitis was the main symptom in 65.1% of children; in 25.6% an association between ingestion of pollen-related foods and nasal symptoms was observed. The simultaneous sensitization to animal origin food allergens was stated in 63.3% of children with SAR. In 25.6% anaphylactic reactions to foods were registered. 37.2% of children were asymptomatic to pollen origin foods despite pollen-food sensitization. The statistically significant differences between values were noticed in comparison to the control group., Conclusions: Allergic rhinitis is a common manifestation of pollen-food sensitization in children and this type of immunological hyperreactivity should be taken into account regardless of age. The lack of association of symptoms with plant origin foods in the majority of cases and the asymptomatic course of food sensitization in more than one third of patients indicates the need for follow-up and being careful in routine recommending the avoidance diet., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Termedia.)

The aim of this study was to assess the incidence of DNA aneuploidy in Polish children with B-cell precursor acute lymphoblastic leukemia (BCP-ALL) and the relationship between aneuploidy and immunological phenotype, age, leukocyte count, S-phase fraction (SPF) and early response to induction chemotherapy assessed by the percentage of residual blast cells in bone marrow aspirates. The study group consisted of 267 patients. DNA content and immunophenotype were assessed in the bone marrow before treatment using multicolor flow cytometry (FC). DNA aneuploidy was detected in 50/267 (19%) patients. High hyperdiploidy was found to be associated with lower leukocyte count (p = 0.006) and common ALL immunophenotype. Flow cytometry analysis revealed that high hyperdiploid BCP-ALL patients showed significantly higher expression of CD9, CD20, CD22, CD58, CD66c, CD86 and CD123 antigens as compared to other groups of ploidy. In contrast, CD45 showed decreased expression. The percentage of leukemic blasts at diagnosis was lower in high hyperdiploid BCP-ALL cases than in diploid (79% vs. 85.7%, p = 0.001). The difference in minimal residual disease (MRD) levels on day 15 and 33 of induction therapy between analyzed groups was not significant. This study showed that high hyperdiploidy is associated with lower WBC count and specific immunological phenotype. Flow cytometric evaluation of expression of selected antigens can be used for fast identification of markers of aneuploidy in pediatric BCP-ALL, before genetic tests results are available. Understanding the biological significance of aneuploidy in leukemia can potentially be exploited therapeutically using targeted therapies against specific blast cell subclones., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Termedia.)

Introduction: Data comparing response to originator and biosimilar infliximab in anti-TNF-α naïve and non-naïve Crohn's disease patients is limited., Aim: To assess the efficacy, safety, and tolerability of a biosimilar infliximab in comparison to the originator drug in anti-TNF-α naïve and non-naïve Crohn's disease patients. Data comparing response in those two groups of patients are limited., Material and Methods: This retrospective single-centre study enrolled 168 adult Crohn's disease patients treated for 1 year with infliximab originator or biosimilar. Assessment included achievement of clinical remission (during induction and maintenance therapy and follow-up period - 24 months) and occurrence of adverse events., Results: Forty-seven patients taking infliximab and 68 on biosimilar were anti-TNF-α naïve. There were no differences in clinical remission rate between naïve and non-naïve patients after 1 year of treatment (infliximab - 80.9% and 73.1%, respectively; biosimilar - 79.4% and 74.1%, respectively). The relapse rate during the follow-up period was higher in anti-TNF-α non-naïve patients ( p < 0.001) with no significant differences between two groups. Adverse events were more common in anti-TNF-α non-naïve patients with no difference between infliximab and biosimilar groups (13.3% vs. 17.6%, respectively). The infliximab group of anti-TNF-α naïve patients had a higher rate of adverse events compared to the biosimilar (8.1% vs. 1.9%), but it did not reach statistical significance., Conclusions: This is a study comparing anti-TNF-α naïve and non-naïve patients with Crohn's disease. Relapse rate during follow-up was significantly higher in anti-TNF-α non-naïve patients, but with no significant differences between originator and biosimilar., Competing Interests: This study was not supported by pharmaceutical industry.

Introduction: Since the skin plays a pivotal role in interpersonal relationships, a chronic dermatological condition (psoriasis), may have a profound effect on the psychological status of patients., Aim: To analyse the effects of skin lesions on satisfaction with life, acceptance of illness and quality of life in psoriasis., Material and Methods: The study included psoriatics recruited at the Dermatology Outpatient Unit of the Regional Hospital in Lomza, Dermatology Outpatient Clinic in Siemiatycze and Dermatology and Medical Cosmetology Centre in Bialystok. The study patients were examined with a demographic survey prepared by the authors, as well as with three validated scales: AIS, SWLS and DLQI. A total of 263 questionnaire sets were handed out to the participants of the study; this pool included 200 questionnaires with complete data that were eventually included in the analysis., Results: Acceptance of Illness Scale scores of the study participants ranged between 8 and 40 pts. Mean AIS scores for female and male psoriatics were similar, 23 and 25 pts, respectively. Based on the distribution of Satisfaction with Life Scale scores, 42 of the study patients presented with high levels of satisfaction with life, whereas 37 and 21 showed moderate and low satisfaction levels, respectively. Quality of life turned out to be the best among 20- to 30-year-old respondents as up to 74.19 of them had Dermatology Life Quality Index scores no greater than 10 pts., Conclusions: Psoriatics with higher levels of illness acceptance also presented with greater satisfaction with life., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2020 Termedia Sp. z o. o.)

Introduction: A small number of studies concern trophoallergens and aeroallergens sensitization in the developmental age population in Poland. Only a few studies describe the role of selected factors determining the frequency and type of IgE-dependent sensitization in this population., Aim: To assess the rate of sensitization to chosen tropho- and aeroallergens in the group of sensitized patients living in the north-eastern region of Poland with regard to age, sex and birth season., Material and Methods: Skin prick testing (SPT) with selected food allergens (trophoallergens) and airborne allergens was used to evaluate the sensitization process of patients recruited to this study between 1998 and 2012. A positive result of sensitization was defined when the patient had at least one positive skin prick test with the allergen studied. The skin prick tests were done after written consent had been obtained from the parents., Results: Significant results were as follows: sensitization was more common in boys (41.9%) than in girls (35.7%); the highest percentage of sensitized patients was observed in the group of children aged 13-18 years (45.0%) as compared to the group of children up to 3 years old (the lowest 33.1%). The highest percentage of sensitized patients was observed among children born during winter (41.3%), the lowest among children born in autumn (36.8%)., Conclusions: The assessment of sensitization to chosen trophoallergens and airborne allergens should include the role of age, sex and birth season of the diagnosed patient., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2021 Termedia Sp. z o. o.)

Introduction: Good evidence has been provided over the last three to four decades that the prevalence of allergic diseases has been increasing in many developed countries worldwide. Recent data suggest that this increase may now be levelling off., Aim: Retrospective analysis of the prevalence of IgE-dependent sensitization and changes in selected environmental allergens in the population of children and adolescents in the north-eastern region of Poland in the years 1998-2012., Material and Methods: Skin prick testing (SPT) with selected food allergens (trophoallergens) and airborne allergens was used to evaluate the sensitization process of patients recruited to the study in the years 1998-2012. A positive result of sensitization was defined when the patient had at least one positive skin prick test with the allergen studied. The skin prick tests were done after written consent had been obtained from the parents., Results: The retrospective study included children and adolescents aged up to 18 years with a suspicion of an allergic disease, referred to the regional tertiary medical centre for further diagnosis. A total of 6577 patients were studied, including 1556 (23.7%) in 1998, 1473 (22.4%) in 2003, 1690 (25.7%) in 2008, and 1858 (28.2%) in 2012. Sensitization to at least one allergen was observed in 39.0% of the examined children (regardless of the allergen type), of which 8.1% were sensitized to food allergens only, 23.9% to airborne allergens only, and 7.0% simultaneously to food and airborne allergens. During the 14-year study period, an increase was noted in the percentage of the sensitized children from 35.3% at baseline to 40.4% when the study was completed. The percentage of those sensitized to food allergens increased from 10.5% (1998) to 20.1% (2012). The percentage of children sensitized to airborne allergens remained unchanged at the level of 28.2% in 1998 and 27.2% in 2012., Conclusions: Measurement of skin prick test reactivity to different allergens is a useful and commonly used method in epidemiological studies for the assessment of allergic sensitization and changes in selected populations. The obtained results confirmed the need for systematic epidemiological research into allergic sensitization and allergic diseases among children and adolescents in Poland., Competing Interests: The authors declare no conflict of interest., (Copyright © 2020 Termedia.)

Introduction: In the course of acute myocardial infarction (AMI) cardiomyocyte injury, activation and destruction of endothelial cells together with inflammation lead to miRNA expression alterations., Aim: To assess levels of circulating cardiac-specific (miR-1) and endothelial-specific (miR-126) miRNAs in the acute phase of AMI and after a follow-up period., Material and Methods: Seventeen AMI patients (mean age: 64.24 ±13.83 years, mean left ventricle ejection fraction (LVEF): 42.6 ±9.65%), treated with primary percutaneous coronary intervention within the first 12 h, had plasma miRNAs isolated (quantitative real-time PCR, Exiqon) on admission and after 19.2 ±5.9 weeks. Measurements were also performed in a control group of healthy volunteers matched for age and sex., Results: Concentrations of both miRNAs were significantly higher in AMI patients as compared to healthy controls: miR-1: 5.93 (3.15-14.92) vs. 1.46 (0.06-2.96), p = 0.04; miR-126: 4.5 (3.11-7.64) vs. 0.54 (0.36-0.99), p = 0.00003, respectively. Levels of both miRNAs significantly decreased after the follow-up period: miR-1: 5.93 (3.15-14.92) vs. 1.34 (0.04-2.34), p = 0.002; miR-126: 4.5 (3.11-7.64) vs. 1.18 (0.49-1.68), p = 0.0005). Moreover, miR-1 correlated positively with maximal troponin I concentration ( r = 0.59, p = 0.02) and negatively with LVEF ( r = -0.76, p = 0.0004)., Conclusions: In our study, miR-1 emerged as a marker of cardiomyocyte injury and loss of myocardial contractility, whereas dynamics of miR-126 concentration may reflect endothelial activation and damage in the most extreme stage of atherosclerosis, followed by angiogenesis in ischemic myocardium. However, to fully elucidate the role of miR-1 and miR-126 as biomarkers of AMI and future therapeutic targets, further research is required., Competing Interests: The authors declare no conflict of interest., (Copyright © 2020 Termedia Sp. z o. o.)

The protective barriers used so far in surgery do not provide adequate protection against SARS-CoV-2 virus, and reinforced protective equipment is needed. The rapid increase in the number of patients and the worldwide panic associated with the increasingly low availability of protective equipment has resulted in a shortage of protective equipment in many hospitals. Appropriatepersonal protective equipment must be provided so that the surgical team proceeding to surgery is not excluded from the further struggle for patients' health, especially in MIS. Reckless and excessive use of maximum protective equipment may result in a severe shortage of these products when the number of infected persons requiring surgery increases. The use of a structured infection risk scheme for medical staff, depending on the results of reverse transcription polymerase chain reaction assays and COVID-19 symptoms, combined with the division of protection equipment into three groups, allows easy selection of an appropriate clothing scheme for the clinical setting., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2020 Fundacja Videochirurgii.)

Introduction: Psoriasis is classified as a psychosomatic disease since its development and outcome may be modulated by various psychological factors. Due to the presence of clinical signs visible to others and poor social awareness of the disease, psoriasis patients are not infrequently classified as different or stigmatized, and their value as human beings tends to decrease., Aim: To analyse the relationship between self-esteem and stigmatization in psoriasis patients., Material and Methods: The study included 120 patients with psoriasis vulgaris. The study participants completed Polish versions of the Rosenberg Self-Esteem Scale (RSES) and the 6-Item Stigmatization Scale developed by Evers et al ., as well as an original survey containing questions about their sociodemographic characteristics., Results: Mean RSES score of the study participants was 24.1 points. Mean RSES score for female patients was nearly 2 points lower than the mean score for men. Analysis of Spearman's rho coefficients showed that the higher the self-esteem in the study participants the less often they considered themselves unattractive to others (0.23), less often believed that people gaze at their skin lesions (0.23) or avoid them because of their condition (0.38)., Conclusions: Our findings demonstrate clearly that both self-esteem and stigmatization are significant components of psoriasis' influence on the patient life. Psoriasis should not be considered merely as a somatic problem, but also as a significant psychological and social burden., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2020 Termedia Sp. z o. o.)

Selection of the optimal peri- and postprocedural antithrombotic regimen in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) is a common clinical problem which may pose a challenge to medical practitioners. This systematic review summarizes the updated evidence on this topic. Non-vitamin K oral anticoagulants (NOACs) at standard doses are the preferred option in most of post PCI patients with AF, except those few with a clear indication for a vitamin K antagonist (VKA). Reduced NOAC doses should be considered in dabigatran- or rivaroxaban-treated patients with a high bleeding risk, which prevail over concerns about stent thrombosis or ischemic stroke. There is insufficient evidence to favor one NOAC over another in this setting. In the early post stenting period, triple therapy comprising a NOAC, clopidogrel and aspirin is recommended. Timing of post PCI aspirin cessation should be based on a careful analysis of the bleeding and ischemic risk. There is only low quality evidence regarding the optimal approach to elective or urgent/emergency PCI procedures in patients requiring oral anticoagulation. It is suggested that there is no need of interruption of VKA and PCI procedure should be performed via radial artery access with a lower dose of unfractionated heparin. On the other hand, NOACs are usually stopped before elective PCIs, while urgent/emergency procedures may be performed with the addition of low-dose parenteral anticoagulation., Competing Interests: Marek Koziński received speaker fees from Bayer, Boehringer-Ingelheim and Pfizer.

Magnetic resonance imaging (MRI) is a widely used method for the diagnosis of multiple sclerosis (MS) that is essential for the detection and follow-up of the disease. The Polish Medical Society of Radiology (PLTR) and the Polish Society of Neurology (PTN) present the second version of the recommendations for examinations routinely conducted in magnetic resonance imaging departments in patients with MS, which include new data and practical comments for electroradiology technicians and radiologists. The recommended protocol aims to improve the MRI procedure and, most importantly, to standardise the method of conducting scans in all MRI departments. This is crucial for the initial diagnostics that are necessary to establish a diagnosis as well as monitor patients with MS, which directly translates into significant clinical decisions. MS is a chronic idiopathic inflammatory demyelinating disease of the central nervous system (CNS), the aetiology of which is still unknown. The nature of the disease lies in the CNS destruction process disseminated in time and space. MRI detects focal lesions in the white and grey matter with high sensitivity (with significantly less specificity in the latter). It is also the best tool to assess brain atrophy in patients with MS in terms of grey matter volume and white matter volume as well as local atrophy (by measuring the volume of thalamus, corpus callosum, subcortical nuclei, hippocampus) as parameters that correlate with disability progression and cognitive dysfunctions. Progress in magnetic resonance techniques, as well as the abilities of postprocessing the obtained data, has become the basis for the dynamic development of computer programs that allow for a more repeatable assessment of brain atrophy in both cross-sectional and longitudinal studies. MRI is unquestionably the best diagnostic tool used to follow up the course of the disease and to treat patients with MS. However, to diagnose and follow up the patients with MS on the basis of MRI in accordance with the latest standards, an MRI study must meet certain quality criteria, which are the subject of this paper., Competing Interests: The authors report no conflict of interest., (Copyright © Polish Medical Society of Radiology 2020.)
