Introduction: The efficacy of management of chronic cough in adults is limited. Speech therapy is one of the few therapeutic methods which seems to be useful in patients with persistent chronic cough. However, the method has not been available in Poland so far. The aim of the study was to implement speech therapy and assess its efficacy in the management of patients with difficult-to-treat chronic cough. Material and methods: Patients, who were diagnosed and managed due to difficult-to-treat chronic cough, were enrolled into the study. Speech therapy was developed on the basis of the technique described by Vertigan. The entire therapy consisted of eight weekly sessions, each lasting 45 minutes. Before and after speech therapy, cough severity and its impact on the quality of life was assessed by the Visual Analogue Scale (VAS) and Leicester Cough Questionnaire (LCQ). Additionally, cough challenge test with capsaicin was performed. Results: Eighteen women were enrolled into the study, 15 of them (83%) attended all treatment sessions (median age 66 years, median duration of cough 60 months). There was a significant decrease in cough severity measured by VAS (46 vs. 28 mm, p = 0.016) after completion of speech therapy. A significant improvement in patients’ quality of life measured by LCQ (10.7 vs. 14.6 points, p = 0.004) and an increase in the threshold of cough reflex measured by capsaicin challenge were also demonstrated. Conclusions: Speech therapy resulted in a decrease in cough severity and improvement of quality of life of females with refractory chronic cough. Our results support the use of speech therapy as add-on treatment in females with difficult-to-treat cough.

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma in the pediatric population. In 35% of cases, RMS develops in the head and neck (H&N) region, and only combined therapy is recognized as a curative treatment. However, recent advances in skull base and reconstructive surgery, along with microsurgery and endoscopic surgery, have strengthened the role of surgery as an important part of RMS treatment. In the present study, 36 pediatric RMS cases (24 males and 12 females) were analyzed after surgical treatment. The average age at diagnosis was 7 years. In total, 67% of tumors were localized in the parameningeal region. Alveolar RMS was the most common histopathological type. A total of 16 patients were treated due to disease recurrence or a previous non-radical surgical procedure, while 19 cases had inductive chemotherapy and/or radiotherapy preceding surgical treatment due to locally advanced disease. In 1 case, only diagnostic biopsy was performed. It is recommended that the management of H&N RMS is interdisciplinary from the beginning. Extensive surgical dissection in the H&N region for RMS may result in severe cosmetic defects and functional impairment; thus, these risks should be considered during treatment planning, and the surgical approach should be based on the individual characteristics of each patient.

In the diversity of the flavor world only five basic tastes have been described. The newest one, umami, has been identified about one hundred years ago by Kikunae Ikeda but widely accepted just in the second half of the twentieth century by international scientific world. There are three umami substances: monosodium glutamate (MSG), inosine-5'-monophosphate (IMP), guanylo-5'-monophosphate (GMP). A real breakthrough in umami history concerned the finding about independent receptors for umami: T1R1 and T1R3 (taste receptors type 1 member 1 and member 3). The palatable, delicious taste of umami and its mechanism determined a lot of research studies on this highlight. Umami substances elicit salivary secretion, enhance appetite and increase food palatability. They are desirable to improve the quality of diet. Moreover, the association between umami substances and the suppression of obesity has been found. Studies suggest that umami is engaged in metabolism but also increases satiety and reduces the post-ingestive recovery of hunger.

Introduction: To evaluate the effectiveness of methylprednisolone (MP) and surgical treatment in achieving complete reversal of dysthyroid optic neuropathy (DON) and predictive factors of this therapy. Material and methods: The group consisted of 10 patients (18 eyes) with DON. The diagnosis of DON was based on at least two criteria from the following: (i) deterioration of visual acuity (VA< 1.0), (ii) loss of colour vision, (iii) optic disc swelling, and/or (iv) signs of DON in magnetic resonance imaging (presence of apical crowding and/or optic nerve stretching). A complete recovery of DON was defined as the normalisation of VA (VA = 1.0), normal colour vision, and reversal of optic disc swelling. A significant improvement was defined as improvement of VA of at least 0.2. The consecutive steps of treatment of DON consisted of: (i) first-line treatment — intravenous MP pulse therapy (3 × 1 g); (ii) second-line treatment — endoscopic intranasal orbital decompression of medial wall; (iii) additional treatment — additional MP therapy and/or surgical decompression. Results: A significant improvement in VA could be achieved in the majority of patients; a complete recovery was noted in 22.2%, 33.3%, and 66.7% of eyes after first-line, second-line, and additional treatment, respectively. Positive predictive factors were: younger age (p = 0.049), shorter duration of DON (p = 0.035), and a higher Graves’ orbitopathy clinical activity score (p = 0.035). Conclusions: By using combination therapy (intravenous MP pulse therapy and surgical decompression), a complete recovery can be achieved in the majority of patients with DON.

In this short introduction to the thematic issue of Theoretical Practice we draw on the Marxist concept of critique to explain how Marxist higher education research could be understood as a constituting practice within-against-beyond the contemporary university in crisis.

Obstructive sleep-disordered breathing (SDB) is a common clinical problem. An unrecognized and untreated SDB is a serious threat for an intensively developing organism of a child. The consequences of SDB include cardiovascular and neurological complications, growth disorders and enuresis. Therefore, SDB in children becomes an important subject of many scientific investigations, publications, and congresses. In 2015 the European Respiratory Society Task Force published a document concerning the conclusions about the diagnostics and treatment of SDB in children and youth from 2 to 18 years of age (Fig. 1). The scientific data from 362 publications were presented in a condensed form of “seven steps”, very useful in diagnosing and treatment planning (1). The authors underline the limited number of reliable evidence about SDB: prospective studies, randomized double-blinded studies with placebo. The presented evidence was categorized depending on their quality according to the classification of the American Academy of Neurology (ANN) into classes I – IV. Previously, in 2012, the guidelines of the American Academy of Pediatrics on obstructive sleep apnea syndrome (OSAS) in children with tonsillar hypertrophy and/or obesity were published (2, 3) and they were a valuable diagnostic and therapeutic compendium. The European guidelines discussed in this article result from the progress of knowledge in recent years, they cover the subject broadly, consider rare and difficult cases and present the spectrum of potential therapeutic actions. The aim of the guidelines is a better recognition of SDB, a systematization of diagnosis and treatment at every stage of medical care, including the causes of this disorder and its complications.

The patient with bacterial infection sequelae in the form of damage to cranial nerves III, IV, and VI was followed up. He had exhibited clinical and radiographic signs of paranasal sinusitis. Before his physiotherapy, the patient received standard treatment with natural and synthetic antibiotics and steroids. After acute signs of infection resolved without any functional improvement, the patient was referred to a rehabilitation unit to undergo neuromuscular re-education of the paralyzed extraocular muscles. Periorbital hydrocortisone iontophoresis and visuomotor exercises with intense ideomotor stimulation led to complete and rapid resolution of extraocular muscle paralysis and diplopia. Physiotherapy can be an effective treatment of choice after failed pharmacological treatment in patients with damage to cranial nerves III and VI. It has many theoretical advantages, including noninvasiveness and avoidance of first-pass metabolism of drugs administered systemically.

Introduction The association between obstructive sleep apnea and atherosclerosis is confirmed for long time, but the pathomechanism is still not known. The aim of this study was to investigate the prevalence of OSA in patients scheduled for endarterectomy and the influence of this procedure on the sleep study parameters and sleepiness. Materials and methods 46 patients scheduled for open carotid endarterectomy were enrolled in the study. Sleep study and Epworth Sleepiness Scale (ESS) was performed preoperatively. In 11 out of 46 patients, sleep study was performed both before and after the surgery. Results The mean age of the group was 69,9 years (± 8,6), 21 patients (45,7%) were female. For 46 patients mean pAHI, ODI, pRDI and %snoring were 16,2 (± SD=15,2), 10,4 (± SD=12,2) and 18,9 (± SD=14,9), respectively. Normal pAHI was noticed in 14 patients (30%), while mild (pAHI 5-15), moderate (pAHI 15-30) and severe (pAHIgt;30) OSA was observed in 13 (38%), 11 (24%) and 8 (18%) subjects, respectively. The mean ESS score for 27 out of 46 patients was 6,3 (± SD=5,6). The postoperative results of sleep study in 11 patients showed no significant change. Conclusions This study revealed the prevalence of moderate to severe OSA in 42% of patients scheduled for endarterectomy, while no excessive daytime sleepiness was observed in this group. The results of the study show that patients with carotid atherosclerosis should undergo sleep diagnosis in order to rule out obstructive sleep apnea.

Purpose of the study: The aim of the study was to present the treatment outcomes after vertical partial laryngectomy with or without pedunculated sternothyroid muscle flap reconstruction following the resection of neoplasm-infiltrated vocal fold. The procedure was used in a patient with glottic cancer. Oncological outcomes, morphology of neo-vocal fold and the act of swallowing were evaluated. Material and methods: 45 patients with T1-T2 glottic cancer were subjected to vertical partial laryngectomy with 26 patients undergoing a procedure with pedunculated sternothyroid muscle flap reconstruction and the remaining 19 patients undergoing a procedure without such a reconstruction. Two female and 43 male patients aged 35-82 years (mean age of 62.5 years) were enrolled in the study. Local tumor spread and the condition of reconstructed vocal fold were assessed in sequential videofiberoscopy examination conducted each month after surgery whereas the regional spread was assessed in ultrasound scans. Postoperative aspiration was graded according to the Pearson’s scale. Results: Six patients experienced local recurrence while 2 patients experienced regional recurrence of the tumor. The pedunculated sternothyroid muscle flap neo-fold was structurally resemblant of the non-affected vocal fold. Episodic, daily dysphagia was observed in 1 patient while normal act of swallowing with no Pearson’s scale symptoms was observed in the remaining 44 patients. No necrosis of pedunculated flap was observed. Conclusions: Vertical partial laryngectomy with or without pedunculated sternothyroid muscle flap reconstruction is a good method for the treatment of low- or intermediate-stage glottic cancer, especially when endoscopic access to the tumor is limited and when CO2 laser cannot be used. No significant functional disorders were observed in operated larynges.

Microvessel density (MVD) corresponds to the intensity of neo-angiogenesis. MVD assessments are based on the expression levels of the vascular endothelium markers such as, e.g., CD34 or CD105. The goal of this study was to assess MVD among patients with head and neck squamous cell carcinoma (HNSCC), and to evaluate the predictive value of MVD in head and neck cancers. The study included 49 patients treated for HNSCC and 11 patients with dysplasia of the upper respiratory tract epithelium. Control tissues consisted of 12 normal mucous membranes of the throat. Expression levels of MVD markers were assessed by immunohistochemistry (IHC) using tissue microarrays (TMA). Clinicopathological factors and patients’ survival over the 5-year follow-up period were analyzed. The MVD/CD34 values were found to be significantly elevated in the HNSCCs compared to the non-malignant control tissues (p = 0.001) and to dysplastic tissues. (p = 0.02). Significantly higher MVD/CD105 values were also seen in the tumor compared to the control tissues (p = 0.001) or the dysplastic tissues (p = 0.001). Unexpectedly, significantly lower MVD/CD34 values were seen in the tumor tissues of patients with the T3–T4 tumors compared to those with T1–T2 tumors (p = 0.01). HNSCCs have statistically higher MVD values compared to dysplasia of the upper respiratory tract epithelium. However, the MVD/CD34 values did not correlate with local invasiveness (the T feature) of HNSCCs. This counterintuitive observation suggests that assessments of MVD as performed on TMA by IHC using anti-CD34 or anti-CD105 antibodies considered to be specific for endothelial cell markers might underestimate the extent of the tumor vascularity in HNSCC.

Laryngopharyngeal reflux (LPR) is a common defect among laryngological and phoniatric patients. Although LPR is categorized as a superficial gastroesophageal reflux disease (GERD), differential diagnosis should treat these two diseases separately. LPR symptoms can be assessed in the interview using as a tool the reflux symptom index (RSI). In addition, changes in the larynx that occur during LPR might be seen during laryngoscopy and classified according to the reflux finding score (RFS). One of the main mucosal irritants in LPR is pepsin which digests proteins and impairs the functions of the upper respiratory tract cells by affecting carbonate anhydrase (CAIII) and the Sep 70 protein. Pepsin initiates inflammatory changes within the larynx, nasopharynx and nasal cavity. The use of pepsin detection in upper and lower throat secretions is a new direction in LPR diagnostics.

Objective: To investigate the pathways of inflammatory spread of extratemporal otogenic complications and present the classification including extratemporal spread of otitis media and mastoiditis. Study design: A retrospective case series at an academic referral center, observational study. Methods: Literature review of rare emergency cases in the course acute otitis media with the development of head and neck abscess. Presentation of different pathways on the lateral and inferior wall of the temporal bone found in computed tomography and during surgery. Results: Inflammatory spread to head and neck following acute otitis media may lead through the mastoid cells (with mastoiditis), external auditory canal, or Eustachian tube. Bezold abscess is the most common extratemporal otogenic neck abscess, but the inflammation may pass through any area of either inferior or lateral wall of the temporal bone, leading to extratemporal complications. Conclusion: Head and neck abscess may complicate the course of AOM and emerges when destruction of lateral or inferior temporal bone surface develops. We can distinguish pathways of inflammatory spread from middle ear to extracranial compartment what should find place in classification of AOM complications.

Objective Congenital cholesteatoma (CC) becomes clinically apparent as a cholesteatoma usually during childhood. Nontraumatic otogenic cerebrospinal fluid (CSF) rhinorrhea with an intact tympanic membrane is a very rare symptom. Methods The review of recent literature and case report of the 60-year old patient – a trumpeter presented with nontraumatic otogenic CSF rhinorrhea, intact tympanic membrane on microotoscopy, and besides colorless fluid in right nasal cavity, normal finding on nasal endoscopy examination. Results CSF rhinorrhea was caused by CC in the petrous bone apex. Early diagnosis was facilitated by computed tomography scanning. Complete cholesteatoma removal was accomplished using a middle fossa craniotomy and an open non-radical antromastoidectomy. Conclusion The diagnosis of otogenic cerebrospinal fluid (CSF) rhinorrhea is challenging and it can easily be misdiagnosed. Congenital cholesteatoma is a rare entity. We present a non-classical presentation of CC in an adult male, with a previously unreported symptom of CSF rhinorrhea. Symptomatic improvement occurred after surgical treatment of the disease.

Introduction. Chronic rhinosinusitis (CRS) affects 14% of the world population. The high motility group box 1 (HMGB1) protein triggers inflammation, cell proliferation and cell survival through its receptor for advanced glycation end products (RAGE) upon release from stressed or necrotic cells. The aim of the study was to analyze the expression and function of HMGB1 and RAGE in CRS, providing more information about HMGB1 signaling pathway in CRS, to determine its potential clinical significance. Material and methods. Thirty-seven patients with CRS and 26 normal controls (NC) were enrolled in this study. Classification of disease severity using the SNOT-20 questionnaire, nasal endoscopy, CT scan, assessment of allergy status, microbiological and cytological analysis was performed in patients. Fresh sinus mucosa samples were obtained and analyzed by immunohistochemistry for HMGB1 and RAGE expression in epithelial cells. ELISA assay was performed to evaluate the concentration of HMGB1 in the patients’ sera. Results. No differences were found in HMGB1 immunoexpression between CRS patients and NC, however there was a highly significant difference in RAGE immunoexpression between both groups. There was a correlation between RAGE expression and number of tissue-infiltrating lymphocytes. Further, RAGE expression positively correlated with disease severity and a positive history for allergies. Conclusions. Interaction of HMGB1 and RAGE might be relevant to CRS pathomechanisms leading to sinus mucosa hyperproliferation. CRS pathogenesis might be especially related to the RAGE overexpression correlated with disease severity and allergy.

Rhabdomyosarcoma (RMS) is the most frequent soft tissue sarcoma in children. It is localized in the head and neck region in 40% of cases. Treatment of RMS is complex, including multi-drug chemotherapy, radiotherapy and surgery. The progress that has been accomplished in oncology in recent decades significantly improved outcomes. The 5-year survival rate raised from 25% in 1970 to 73% in 2001, according to IRS-IV data. The outcome is influenced by primary tumor localization, clinical staging, histological tumor type and age at the moment of diagnosis. The relatively rare incidence of these tumors resulted in difficulties in creating more standardized therapeutic protocols. Comparison of outcomes in large patients groups led to an increase in the number of patients with complete remission. Although survival rates of RMS patients have improved, searching for new therapeutic modalities and substances is still essential to improve outcomes in cases of more advanced stages and unfavorable tumor localizations.

Sternberg's canal is a congenital bony defect in the lateral wall of the sphenoid sinus. If it persists to adulthood, it may become a source of spontaneous cerebrospinal fluid leak (CSF) and meningoencephalocele. The aim of the study was to describe the authors’ experience and review articles related to spontaneous sphenoid sinus CSF leaks and Sternberg's canal. We analysed patients managed surgicallly due to sphenoid sinus CSF leak and performed a PubMed database search. Two female patients with spontaneous CSF leak of sphenoid origin were found. Both patients underwent surgery with the endoscopic endonasal approach, and the defect was closed using the multi-layer technique. Twelve articles related to CSF leaks of sphenoid origin (due to Sternberg's canal) were found in the PubMed database. Lines of lesser resistance within sphenoid bone may underlie CSF leak pathology together with intracranial hypertension. The endoscopic transnasal approach to the sphenoid sinus is an excellent alternative to standard transcranial procedures.

A receptor for advanced glycation end products (RAGE) and its ligand high mobility group box 1 (HMGB1) protein has been linked to several chronic diseases, and acts as a trigger for inflammation signaling. Here, we study RAGE and HMGB1 expression in chronic, recalcitrant rhinosinusitis with nasal polyps (CRSwNP) to determine its potential clinical significance, i.e., disease recurrence and severity. RAGE and HMGB1 expression in CRSwNP was evaluated by immunohistochemistry in epithelial cells of fresh sinonasal mucosa samples obtained from the patients diagnosed with recalcitrant CRSwNP (n = 25) and normal control mucosa (NC) (n = 26). RAGE and HMGB1 expression levels in tissues were correlated with disease severity assessed by nasal endoscopy, CT scan, number of previous sinus surgeries, allergy status and nasosinusal microbiology. RAGE and HMGB1 were moderately or strongly expressed in CRSwNP tissue. No or weak RAGE expression was found in NC. HMGB1 was equally strongly expressed in NC. We observed a strong correlation between RAGE and disease severity, recurrence, undergone operations, asthma and aspirin exacerbated respiratory disease (AERD). Elevated RAGE expression is associated with increased disease severity, as well as allergy and AERD in patients with recalcitrant CRSwNP. It is possible that the explanation for recurrent CRSwNP pathogenesis might be related to RAGE overexpression with subsequent sinus mucosa hyperproliferation, necessitating several operations.

Objective: The aim of the study was to assess the safety and efficacy of high- and low-dose oral, delayed-release mesalamine in a randomized, double-blind, active control study of children with mild-to-moderately active ulcerative colitis. Methods: Patients ages 5 to 17 years, with a Pediatric Ulcerative Colitis Activity Index (PUCAI) score of ≥10 to ≤55 and a truncated Mayo Score of ≥1 for both rectal bleeding and stool frequency, were enrolled. They received body weight–dependent doses of oral, delayed-release mesalamine for 6 weeks in a low- (27–71 mg · g−1 · day−1) or high-dose group (53–118 mg · g−1 · day−1). The primary endpoint was treatment success, defined as the proportion of patients who achieved remission (PUCAI score

Objective: The aim of the study was to estimate usability of the piezoelectric knife in larynx surgery. Prove that the piezoelectric staff can be used to do any different shape incision within the larynx cartilages. Material and methods: 35 patients hospitalized in our Department in 2014–2016 were enrolled in our study. 24 patients went vertical partial laryngectomy and 1 patient went horizontal partial laryngectomy because of larynx cancer. 5 patients went partial laryngectomy because of low stage of piriformis recess cancer. Piezoelectric staff was used to do thyroidectomy and resection of thyroid cartilage suspected of carcinomatosis infiltration. The rest 4 patients had done widening of larynx lumen due to larynx stenosis or slenderness. The piezoelectric tool was used to do different incision or resection within the larynx cartilages in case of widening lumen of the larynx. Results: The larynx cartilages, especially thyroid cartilage could be cut in different shapes using piezoelectric tools. The usage of this equipment causes the minimal loss and small destruction of local healthy tissues. Conclusions: The Piezoelectric instrument is useful instrument suit to operate within larynx cartilages. Exchangeable tip available in different shapes enables different resections of cartilages. Using the piezoelectric staff we can remove pathological tissue with minimal local destruction. Our observation shows that larynx operation with a usage of the piezoelectric knife is safe and effective. Current English literature does not describe usage piezoelectric tools in larynx surgery. It is essential to do more observation about that type of operations.

Cholesteatoma represents progressive expansion of the keratinizing squamous epithelium in the middle ear with subsequent chronic inflammation in subepithelial connective tissues. The hypothesis was tested that receptor for advanced glycation endproduct (RAGE) and its ligand, high-mobility box 1 (HMGB1), are overexpressed in cholesteatoma, and the RAGE/HMGB1 axis might contribute to its pathogenesis. Cholesteatoma samples (n = 36) and 27 normal skin specimens were studied by immunohistochemistry (IHC) for HMGB1 and RAGE expression. Effects of HMGB1 signaling on proliferation, migration, cytokine production, and apoptosis of human immortalized keratinocytes (HaCaTs) and normal keratinocytes were studied by quantitative reverse transcription (qRT)-PCR, IHC, Western blots, and flow cytometry after cell co-incubation with HMGB1. While all studied tissues expressed HMGB1, its expression was higher in cholesteatoma than in normal skin (p

Vascular anomalies are divided according to the contemporary system of classification into two groups: tumors and malformations. However, there is no consensus on juvenile angiofibroma’s place in that system. The general characteristics of selected markers of angiogenesis and tissue remodeling are presented in the series in the context of current knowledge in the field of pathophysiology of vascular lesions. The mentioned markers are currently the subjects of multidirectional studies in oncology, as they take part in the process of neoangiogenesis and proliferation of tumors. Nevertheless, they have not been widely examined in vascular lesions. The indirect goal of that series is to indicate the possible research direction on vascular lesions to determine their molecular profile, to create a more specific system of classification, and above all to develop new diagnostic and treatment methods.

Introduction In recent years there has been an increasing number of cases of cancer, including cancer of the larynx. The choice of treatment should be primarily dictated by the complete elimination of cancer, but from the point of view of the patient, an important factor to keep in mind, is the quality of the voice that will be created at the end of the therapeutic process. Aim The aim of this study was to evaluate the voice quality of patients after partial surgery of the larynx with vocal fold reconstruction pedunculated sterno-thyroid muscle flap. Materials and Methods The study included 30 men aged 53–72 years who were treated at the Clinic of Otorhinolaryngology Department of Medical-Dental Medical University of Warsaw on account of cancer of the larynx, qualified according to the TNM classification T1 or T2. The radical removal of cancer was associated with resection of one vocal fold, laryngeal pouches and ventricular fold. In 15 patients, included to the group I at the end of phase oncology surgery, a reconstruction of “vocal fold” pedunculated sterno-thyroid muscle flap were performed simultaneously. The group II consisted of 15 patients who underwent surgery that removed only the cancerous lesions. Impact assessments arising after surgery of voice disorders on quality of life were made using the self-test failure of the voice (Voice Handicap Index in the Pruszewicz modification). The nature of the created voice was studied using GRBAS scale. All patients performed the laryngostroboscope examination. With “IRIS” program, prepared by a team at Wroclaw University of Technology, the voice was recorded, and then was subjected to acoustic analysis. In addition, noise level and the maximum phonation time was measured. Results The results indicate that the patients of group I gained a better voice confirming the values of objective acoustic analysis. The assessment made by the scale GRBAS patients who supplemented the resulting loss after tumour removal, with much less hoarseness of voice, did not have the hyperkinesis and there was no puff character. They had the better flow of voice and phonation time of vowels “a” was much longer. The assessment of quality of life of patients in group I made in a test of the VHI was higher than in group II. The laryngostroboscope examination confirmed a good phonatory occlusion and a nearly regular, healthy vocal fold vibration in patients who had received flap of muscle. Conclusions Evaluation of the quality of voice after removing the tumor multiplicity in the glottis with simultaneous reconstruction “vocal fold” has confirmed that this is a very good surgical technique, which allows radically curing cancer for the simultaneous preservation of a good voice. The operation has limited indications for radiotherapy because of the desire to preserve the phonatory function of the larynx, and thus avoids the negative effects of radiation.

Background: Bitter taste receptors (T2Rs), especially T2R38s appear as innovative regulators of innate immunity in the respiratory system. The single nucleotide polymorphisms (SNPs) in TAS2R38 gene may contribute to individual differences in susceptibility to respiratory infections especially chronic rhinosinusitis (CRS). TAS2R38 genotypes distribution varies by geographic region, race and ethnicity. The aim of the preliminary study was the identification of SNPs in TAS2R38 encoding genes in Polish patients with CRS and finding potential correlation with CRS phenotypes. Material and methods: The preliminary study contained 20 CRS patients undergoing functional endoscopic sinus surgery (FESS). Fresh sinus mucosa (SM) was obtained during FESS in CRS patients. Patients were genotyped for TAS2R38 using Sanger method and the genotype occurrences of the clinically recalcitrant CRS cohort was evaluated. Analysis of TAS2R38 expression in SM of CRS patients was performed using immunohistochemistry (IHC). Results: T2R38 was highly expressed in SM of CRS patients. Patients with CRS demonstrated both common genotypes PAV, AVI. The heterozygotes frequency (AVI/PAV) was the highest. The protective genotype (PAV/PAV) was noticed in the lowest frequency and connected with lower average value of CT score compare to AVI/AVI genotypes (p=0.01). Conclusions: The work presented in this study provides the hypothesis that airway bitter T2Rs are an innovative sphere of human respiratory innate protection. TAS2R38 polymorphism may influence the susceptibility to CRS. The AVI haplotypes are an independent risk factors for CRS. Additionally, the bitter taste receptors and related signalling pathways might create an unique group of therapeutic targets to treat CRS.

Wstęp: Skuteczność leczenia przewlekłego kaszlu u dorosłych jest ograniczona. Terapia mowy to jedna z niewielu metod leczenia, które wydają się skuteczne u pacjentów z uporczywym, przewlekłym kaszlem. Metoda ta jednak nie była dotychczas dostępna w Polsce. Celem badania było wdrożenie terapii mowy i ocena jej skuteczności w leczeniu pacjentów z przewlekłym, uporczywym kaszlem. Materiał i metody: Pacjenci diagnozowani i leczeni z powodu przewlekłego, niepoddającego się leczeniu kaszlu zostali włączeni do badania. Terapię mowy opracowano na podstawie techniki opisanej przez Vertigan i wsp. Składała się z ośmiu 45-minutowych spotkań, odbywających się raz w tygodniu. Przed i po zastosowaniu terapii mowy oceniano nasilenie kaszlu i jego wpływ na jakość życia przy zastosowaniu analogowej skali wizualnej (VAS, visual analogue scale) i kwestionariusza jakości życia przeznaczonego dla chorych z kaszlem (LCQ, Leicester Cough Questionnaire). Dodatkowo wykonywany był test prowokacyjny z kasacyjną oceniający wrażliwość odruchu kaszlu. Wyniki: Do badania włączono 18 kobiet, ale tylko 15 (83%) z nich wzięło udział we wszystkich sesjach (mediana wieku 66 lat, mediana czasu trwania kaszlu 60 miesięcy). Po zakończeniu terapii mowy stwierdzono istotne zmniejszenie nasilenia kaszlu ocenianego w skali VAS (46 v. 28 mm, p = 0.016), istotną poprawę jakości życia ocenianej w LCQ (10.7 v. 14.6 punktu, p = 0.004) oraz zwiększenie dawki kapsaicyny wywołującej kaszel w teście prowokacji. Wnioski: Zastosowanie terapii mowy spowodowało zmniejszenie nasilenia kaszlu i poprawę jakości życia kobiet z przewlekłym, uporczywym kaszlem. Wyniki niniejszego badania wskazują na skuteczność dołączenia terapii mowy do leczenia kobiet z uporczywym, przewlekłym kaszlem.

Background & Aims We studied the reliability of the previously described Ulcerative Colitis Endoscopic Index of Severity (UCEIS) and validated it with an independent cohort of investigators. Methods We created a new library of 57 videos of flexible sigmoidoscopy and stratified them based on disease severity. Twenty-five investigators were each randomly assigned to assess 28 videos (which included 4 duplicates to assess intraobserver reliability). Investigators were blinded to clinical details except for 2 of 4 duplicated videos (to assess the impact of knowledge of symptoms on assessment). Three descriptors ("vascular pattern", "bleeding", and "erosions and ulcers") comprising the UCEIS were scored with a visual analogue scale (VAS) to assess overall severity. Intrainvestigator and interinvestigator agreement was characterized by κ statistical analysis; reliability ratios were used to compare VAS and UCEIS scores. Results There was a high level of correlation between UCEIS scores and overall assessment of severity (correlation coefficient, 0.93). Internal consistency (Cronbach α analysis) was 0.86. Intrainvestigator and interinvestigator reliability ratios for UCEIS scores were 0.96 and 0.88, respectively. Intrainvestigator agreement in determination of the UCEIS score was good (κ = 0.72), with individual descriptors ranging from a κ of 0.47 (for bleeding) to 0.87 (for vascular pattern). Interinvestigator agreement in determination of UCEIS scores was moderate (κ = 0.50), with descriptors ranging from a κ of 0.48 (for bleeding) to 0.54 (for vascular pattern). Intrainvestigator variability in determining UCEIS scores did not change appreciably when a video was presented with clinical details. Conclusions The UCEIS and its components show satisfactory intrainvestigator and interinvestigator reliability. Among investigators, the UCEIS accounted for a median of 86% of the variability in evaluation of overall severity on the VAS when assessing the endoscopic severity of UC and was unaffected by knowledge of clinical details.

Summary Objectives PRAME (Preferentially Expressed Antigen in Melanoma) is a tumor-associated antigen recognized by immunocytes, and it induces cytotoxic T cell-mediated responses in melanoma. PRAME expression in tumors interferes with retinoic acid receptor (RAR) signaling thus promoting tumor progression. Here, we study PRAME expression in head and neck squamous cell carcinoma (HNSCC) to determine its potential clinical significance. Materials and methods PRAME expression in HNSCC was evaluated by immunohistochemistry in tissue microarrays of primary tumors (n = 53), metastatic lymph nodes (n = 8) and normal oral mucosa (n = 11). Biopsies of dysplastic oral lesions (n = 12) were also examined. PRAME expression levels in tissues were correlated with markers of poor prognosis in HNSCC. PRAME mRNA in HNSCC cell lines and in normal immortalized human keratinocytes (HaCaT cell line) was measured by qRT-PCR, and the protein expression by flow cytometry and western blots. Results PRAME was expressed in HNSCC cell lines and HNSCC lesions. PRAME expression in dysplastic mucosa was variable. No or only weak expression was found in normal cells or tissues. PRAME expression levels significantly correlated with the tumor grade, size, nodal involvement and the clinical status of HNSCC patients. Conclusions Elevated PRAME expression associates with clinicopathologic markers of poor outcome in HNSCC and might identify potential candidates with pre-cancerous lesions for chemoprevention with retinoids.
