Opis:
Introduction: Nasal and paranasal sinus polyps are one of the most common laryngological problems. Often, despite surgical treatment of nasal and paranasal sinus polyps, they grow back and require surgical retreatment. It is very difficult to predict which patients are particularly exposed to it. Markers are still being sought to predict which patients are particularly exposed to regrowth of polyps and thus require increased clinical surveillance. Galectins are a group of glycoproteins that have been intensively studied recently. The sugar part of these proteins can play a role in transmitting intercellular signals. Laryngologists are especially interested in galectins-1 and -3. The determination of their increased content in cancer tissue is considered as a marker of malignancy, which worsens prognosis in patients. Recently, more and more attention has been paid to the role of galectins in benign lesions, and such are the nasal and paranasal sinus polyps. Materials and methods: In our work, the contents of galectin-1 and-3 were determined in the tissue of the surgically removed primary (n = 35) and recurrent polyps (n = 15). R esults: The content of galectin-1 and-3 showed no statistically significant differences between primary and recurrent polyps. Conclusions: The content of galectin-3 was lower in recurrent polyps, however the observed difference did not reach statistical significance (p = 0.07). Since the obtained „p” value is close to the significance limit, it is advisable to broaden the submitted studies to a larger group of patients in order to be able to fully assess whether the determination of the content of galectin-3 may be helpful in assessing the risk of recurrence of nasal and paranasal sinus polyps.

Aim: The aim of the study was to retrospectively assess the relationship between the occurrence of polyps and colon cancer in patients with type 2 diabetes. Methods: In 2014–2015, 976 colonoscopies were performed in patients. We compared the number of polyps with high-grade dysplasia and colorectal cancers in patients with and without diabetes. In addition, in the diabetic group we documented the relationship between HbA1C and the occurrence of polyps with high-grade dysplasia, and colon cancer. The data were statistically analyzed. Results: 1. Patients with diabetes show a higher incidence of polyps with high-grade dysplasia/carcinoma – 32/91 (35.16%) in comparison to patients without diabetes – 136/885 (15.37%), P < 0.001; 2. Patients with diabetes show a higher incience of polyps with cancer – 9/91 (9.89%) as compared to patients without diabetes – 18/885 (2.03%), P < 0.001. 3) Colorectal cancer occurred significantly more often in uncontrolled diabetes (P = 0.022). Conclusion: The conducted study shows a significant association between type 2 diabetes and the incidence of colorectal adenomas. These findings may lead to a conclusion that diabetic patients are at a higher risk of developing colorectal cancer, thus are in higher need for controlled colonoscopy. Therefore, it may be worth considering a scheme for screening patients in the above-mentioned group with colonoscopy.

Opis:
CRS is a process involving a number of adverse changes in the mucosa of the paranasal sinuses and nasal polyps, e.g. increased fibroblast proliferation, angiogenesis, increased formation of fibrous tissue (subepithelial fibrosis) and tissue destruction. There are biomarkers whose levels can be increased in chronic inflammation of the paranasal sinuses: peripheral blood eosinophilia, IgE immunoglobulin, cytokines – IL-4, IL-5, IL-13, IL-25, IL-33, periostin, P-glycoprotein, CXCL-12, CXCL-13, INF-Υ, TNFα, TGFβ1, albumins, eotaxin. These biomarkers are not pathognomonic for CRS. The concentration of biomarkers is also increased in bronchial asthma and atopic dermatitis. The TGFβ, in particular the β1 subunit, was identified as the main factor involved in the remodelling of tissue stroma. In conjunction with continuous improvement of tissue testing methods, it is advisable to search for new factors that will more accurately allow the assessment of tissue remodelling in the chronic processes of paranasal sinuses.

Introduction: The aim of the study was to assess the effect of nasal mucosa irritants on the occurrence of chronic rhinosinusitis without/and with nasal polyps. Material and methods: The study involved 100 adult participants, including 39 women and 61 men, aged 21–68, diagnosed and treated at the Department of Otolaryngology, ENT Oncology, Audiology and Phoniatrics at the University Clinical Hospital WAM in Łódź. Based on the otorhinolaryngological and imaging (CT) tests they were divided into two groups: I – 50 patients, including 23 women and 27 men, aged 21–64 – with chronic rhinosinusitis without nasal polyps, II – 50 patients, including 16 women and 34 men, aged 22–68 – with chronic rhinosinusitis with nasal polyps. The control group consisted of 50 people (group III), including 25 women and 25 men, aged 18–30, students of the Faculty of Military Medicine at the Medical University of Lodz. All respondents completed a prepared questionnaire consisting of 17 questions addressed in the form of an anonymous interview among patients treated in the Department of Otolaryngology, ENT Oncology, Audiology and Phoniatrics. Results: The conducted surveys indicate the impact of the following factors in pathogenesis of chronic rhinosinusitis without/ with nasal polyps: exogenous factors (viruses, bacteria, fungi, drugs, injuries, toxic substances, environmental pollution), general endogenous factors (allergy, hypersensitivity to acetylsalicylic acid and its derivatives, hormonal disorders, supraesophageal reflux disease, granulation disease, immunity disorders, local endogenous factors. Conclusions: In the examined material, patients with chronic rhinosinusitis without/and nasal polyps in most cases are in the age range 51–60 years and over 60 years, they most often live in large cities over 250 thousand inhabitants, suffer from allergic rhinorhinitis in 38.0% in group I and 36.0% in group II, rapid temperature changes and dry air have a negative impact on comfort of breathing. The conducted surveys confirm that the cause of chronic rhinosinusitis with polyps is multifactorial, but a significant factor affecting typical tissue remodeling in this disease is long-term breathing of polluted atmospheric air.

Introduction: A randomized, double-blind, placebo-controlled study investigates the use of bacteriophages in the treatment of chronic rhinosinusitis with nasal polyps. Material and methods: 40 adult patients with chronic rhinosinusitis with nasal polyps were examined. All patients underwent functional endoscopic sinus surgery. After the surgery, 20 patients were administered an intranasal gel with bacteriophage mixture (Otofag, Micromir, Russia) twice a day for ten weeks, while 20 other patients received a placebo solution. Results: On the 10th day, IL-1β secretion diminished (63 mg/ml versus 440 mg/ml in control). There was a decrease in the total number of microorganisms and Enterobacteriaceae (5.7 x 106 CFU/ml versus 1.2 x 109 CFU/ml in the control group) and the absence of Streptococci (versus 2.1 x 109 CFU/ml in control) was noted on the 30th day of treatment in the group receiving bacteriophage mixture. On the 10th day, a decrease in the activity of secretory IL-1β and IL-8 strongly and very strongly correlated with a total number of microorganisms (r = 0.7; r = 0.9, respectively), as well as a decrease in the activity of secretory IL-8 correlated with the number of Enterobacteriaceae (r = 0.72) and Staphylococci (r = 0.65) in the experimental group treated with bacteriophages. On the 30th day, the decrease in serum IL-1β significantly correlated with the total number of microorganisms (r = 0.80) and Enterobacteriaceae (r = 0.90) in the experimental group. Conclusions: The administration of bacteriophages restored the balance of microorganisms in the nasal cavity and decreased inflammatory response in chronic rhinosinusitis with nasal polyps. Changes such as an inflammation dampening could potentially contribute to reducing recurrent growth of polyp tissue in the future.

Opis:
Introduction and objective. Screening colonoscopy is a recommended tool, and the most sensitive and cost-effective method for reducing the incidence of colorectal cancer (CRC). Objective. The purpose of the study was to present the results of a 5-year screening for early detection of CRC carried out among the population of the central-eastern regions of Poland, primarily in Lublin Province. Materials and method. Screening colonoscopy was conducted in a group of 1,009 patients – 636 women and 373 men, aged 40–65 years. Results. Neoplastic polyps were found in 275 patients, advanced adenomas in 49 patients and adenocarcinoma in 13. 70.55% of neoplastic polyps was located in the distal colon, 18.9% in the proximal part and 10.55% in both regions, advanced adenomas in 79.59%, 8.16% and 12.25%, respectively. Adenocarcinoma was located in the proximal colon in 2 cases and in the distal region in 11 cases. Neoplastic polyps and advanced adenomas occurred significantly more frequently in smokers than in non-smokers. Neoplastic polyps were found statistically more frequent in males than in females, among the overweight and obese patients, than in subjects with normal BMI, and more frequently in the group of urban, compared to rural patients. However, the frequency of advanced adenomas and CRC was not statistically different in those groups. The incidence of CRC was statistically more frequent in males than in females. Smoking and male gender were significant risk factors for developing neoplastic polyps. Male gender seemed to predispose to CRC. Obesity was found to favour advanced adenomas. Conclusions. The results of screening found neoplastic polyps in every third person (mean) who did not have any symptoms suggestive of colon pathology. Advanced adenomas were found in 5% of the examined and CRC was detected in 1.29% of participants. Smoking, male gender and overweight were significant risk factors for developing neoplastic polyps. No correlation was found between gender and the location of neoplastic polyps and advanced adenomas in the colon.

Opis:
Due to the constant increase of public health awareness and widespread “cancerophobia”, the progressively larger number of incidentally diagnosed gall-bladder polyps became the source of anxiety, which leads patients and physicians to undertake therapeutic decisions, despite the absence of symptoms. The majority of gall-bladder polyps are benign. It is estimated that only 3 to 5% of polyps are malignant. Currently, there is lack of randomized control trials based on which the clear-cut criteria of qualification of patients with gall-bladder polyps for surgical procedure can be created. The aim of the study was to analyze gall-bladder polyps in patients who underwent laparoscopic cholecystectomy in the 2nd Department of General Surgery, Jagiellonian University Collegium Medicum. Material and methods. The retrospective study was conducted on 5369 patients who underwent laparoscopic cholecystectomy in the 2nd Department of General Surgery, Jagiellonian University Collegium Medicum with special attention to 152 (2.8%) patients in whom gall-bladder polyps were diagnosed preoperatively. Qualification criteria for surgery, surgical treatment results, and histopathological examination results were also analyzed. Results. Amongst the 5369 patients qualified for laparoscopic cholecystectomy, 152 (2.8%) were diagnosed with gall-bladder polyps during the preoperative ultrasound examinations. Postoperative histopathological examinations of 41 (27%) patients confirmed the presence of gall-bladder polyps. In 102 (67%) patients, only gall-stones were diagnosed without previously described polyps during the ultrasound examination. Analysis of the histopathological examination results revealed the presence of benign lesions in 35 (23.35%) patients. In 5 (3%) patients the presence of an adenoma, and in one (0.65%) the presence of adenocarcinoma were confirmed. Conclusions. Based on the conducted study and previous personal experience in the treatment of patients with gall-bladder polyps, we believe that due to the potential risk of neoplastic transformation, patients with polyps larger than 10 mm in diameter and polyps of proven rapid growth should be qualified for laparoscopic cholecystectomy. Indications for surgical treatment also seem reasonable in case of patients with present polyps and coexisting right upper quadrant pain, even though the above-mentioned is connected with gall-bladder deposits.

Opis:
Vitamin D (VD) and its different analogues, besides their classic role as regulators of calcium and phosphor homeostasis, have emerged as a large family of antiproliferative agents. Such properties suggested VD potential as a therapy for chronic inflammatory diseases, including nasal polyposis (NP). NP growth involves both an inflammatory process and the proliferation of fibroblast as an important factor inducing aberrations in the phenotype of the epithelium. The aim of this study was to investigate the possible influence of 1α,25-dihydroxyvitamin D3 (calcitriol) and 1α,24(R)-dihydroxyvitamin D3 (tacalcitol) in monotherapy and in combination with budesonid R (BR) on NP fibroblast proliferation. Material and methods: The study involved 26 samples of NP. NP cells were cultured on 96-well plates beginning with a concentration of 5 × 103 cells per well with RPMI 1640 medium supplemented with antibiotics and 10% foetal bovine serum. After the fourth to sixth passage the medium was replaced with a nutrient medium with calcitriol or tacalcitol in a defined concentration (from 10-9 M to 10-3 M) alone or in combination with BR in 1:1, 1:3 or 3:1 ratios, each at concentrations from 10-5 M to 10-3 M. Results: Growth inhibition of nasal fibroblasts exposed to calcitriol or tacalcitol was noted. Significant antiproliferating activity was observed at calcitriol concentrations of 10-4 M and 10-3 M after 48 h, and at a concentration of 10-3 M after 72 h with the percentage of proliferating cells reduced to 30% compared to the control samples (P < 0.05). In cells treated with tacalcitol the maximal effect was seen at 10-4 M after 48 h and at 10-3M after 72 h with a 60% inhibition with respect to the control (P < 0.05). The inhibition of fibroblast proliferation reached the maximal level when they were exposed to calcitriol: BR (1 : 1) or tacalcitol: BR (1 : 1), each at a concentration of 10-4 M, after 72 h (82% and 69%, respectively). Conclusions: The antiproliferative activity of calcitriol and tacalcitol in NP cultures was confirmed. Because of its lower toxicity and higher activity tacalcitol seems to be the more promising agent in NP therapy, both as a single medication and in treatment protocols with BR.

Opis:
Chronic rhinosinusitis with nasal polyps (CRSwNP) is a disease with still not enough known pathogenesis despite the development of genetics, immunological and microbiological research. The number of patients with CRS has been constantly growing. The coexistence of CRS, bronchial asthma and aspirin intolerance (aspirin triad) is an adverse prognostic factor with higher risk of recurrences. The aim of study was to compare the severity of CRSwNP depending of coexistence of bronchial asthma and/or aspirin intolerance. The research was performed in the group of 204 patients operated 2009-2013 with 5 years follow-up. Higher nasal polyps growth in groups of patients with aspirin triad and CRSwNP and bronchial asthma in endoscopic examination (p=0,0005 and p=0,0030 respectively) and CT-scan according to Lund-Mackay point scale (p<0,0001 and p=0,0009) was showed. Also, these patients presented increased severity of nasal symptoms before surgical treatment according to VAS scale (p=0,0126 for CRSwNP with bronchial asthma; p=0,0390 for aspirin triad). Similarly, 6 months after surgery the same groups of patients presented higher severity of the disease symptoms (p<0,0001 for aspirin triad’ patients; p=0,0174 for CRSwNP and bronchial asthma’ patients) . Patients with aspirin triad had also statistically more surgeries in past (p=0,001), what proves that recurrences in this group are very likely to be observed in spite of the use of proper conservative treatment. No such differences have been shown in the group of patients with CRSwNP and isolated aspirin intolerance (without bronchial asthma). Allergy to inhaled allergens, hypersensitivity to aspirin are factors significantly worsening the course of CRSwNP. It would be advisable to consider, despite a lack of history of aspirin intolerance, a hypersensititvity to aspirin test in patients with particularly severe CRSwNP, especially those associated with bronchial asthma. It also seems reasonable to carry out such a test on every patient with newly diagnosed CRSwNP and bronchial asthma in order to be able to plan further treatment in this group of patients accordingly including biological treatment with antimonoclonal therapy against interleukin 4, 5 or13.

The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 also abbreviated to EPOS2020, is the new edition of the European document devoted to the broadly understood topic of inflammation of the nasal mucosa and paranasal sinuses. The first edition appeared in 2005, followed by further editions in 2007 and 2012. In February 2020, we received the latest version, extended, somewhat modified, expanded to include the latest research and meta-analysis in the fields of: rhinology, rhinosurgery, epidemiology and reports on comorbidities. A completely new division of chronic sinusitis was presented. Recommendations based on the highest quality evaluations, resulting from the publication of the last eight years, also introduce a system based on integrated care pathways, or ICP in sinusitis. Chapters on pediatric aspects and sinus surgery have been expanded. EPOS2020 is addressed not only to doctors, but also to: nurses, pharmacists, other healthcare workers, as well as patients themselves, who often make the first attempts at treatment with OTC preparations, frequently based on the recommendations of pharmacists. The latest EPOS also specifies directions for further lines of research in the broadly understood field of rhinosinusitis.
