Simplified Modelling of the Edge Crush Resistance of Multi-Layered Corrugated Board: Experimental and Computational Study.

The edge crush test is the most popular laboratory test in the corrugated packaging industry. It measures the edge crush resistance of a sample in the cross-fiber direction (CD), also known as the ECT index. This parameter is widely used for the specification of the board by its producers.

The "cholesterol paradox" among inpatients - retrospective analysis of medical documentation.

Introduction: There is evidence of positive relationships between cholesterol concentration and risk of cardiovascular diseases. However, higher mortality in patients with a low cholesterol level has been reported (the "cholesterol paradox").

Material And Methods: Medical records of 34 191 inpatients between 2014 and 2016 were reviewed and the relationships between total (TC), low-density lipoprotein (LDL-C) and high-density lipoprotein (HDL-C) cholesterol and triglyceride blood concentrations and all-cause in-hospital death and readmission within 14 and 30 days and 1 year were determined in univariate and multivariate analyses.

The usefulness of narrow band imaging in the assessment of laryngeal papillomatosis.

Objectives/hypothesis: Recurrent respiratory papillomatosis (RRP) is a benign disease caused by human papillomavirus 6 and 11. The characteristic feature of this disease are wart-like lesions covering the respiratory epithelium with a predilection for the larynx. There is no curative treatment for the disease.

Body mass index as a biomarker for the evaluation of the "Obesity Paradox" among inpatients.

Background: Overweight and obesity are, on the one hand, recognized as risk factors for many health-related disorders, and, on the other, as favorable prognostic factors in various patients treated for several different conditions; what is called the "obesity paradox". Until now, the existence of this phenomenon among a general population of consecutive inpatients has not been evaluated. We decided, therefore, to perform an evaluation.

Primary and salvage laser surgery of 341 glottic cancers-Comparison of treatment outcomes between University Head Neck Tertiary Referral Center and Local Head Neck Department.

Objective: The main goal was to compare the clinical data of patients with T1 and T2 glottic cancer treated with CO transoral laser microlaryngoscopy (TLM) in the Tertiary Referral University Department of Otolaryngology, Head Neck Surgery, Poznan and the local Department of Otolaryngology, Oncology and Maxillofacial Surgery, Bydgoszcz.

Material And Methods: Unified databases for the 7-year period January 2005-December 2011 were created to compare these two cohorts. The database contained 341 patients: 231 from the tertiary center and 110 from the local department, of which 298 (87%) were men, and 43 (13%) were women.

The incidence of laryngeal cancer in Europe with special regard to Poland in last 2 decades.

Objective: Laryngeal cancer is a common respiratory cancer. We aimed to use data from European population-based cancer registries to present variations in the incidence and mortality of laryngeal cancer within Europe.

Methods: High-quality data from cancer registries were qualified for analysis.

Autofluorescence spectroscopy in the differentiation of laryngeal epithelial lesions - preliminary results.

Conclusions Autofluorescence spectroscopy may be a supporting tool for differential diagnosis of changes in laryngeal epithelium. Objectives Early detection and differential diagnosis of proliferative changes in the larynx are still a challenge for laryngologists. The aim of the study was to evaluate the autofluorescence spectroscopy technique to in vitro differential diagnosis of pathological changes in the epithelium of the larynx.

Cochlear implant and congenital cholesteatoma.

Background: The occurence of cholesteatoma and cochlear implant is rare. Secondary cholesteatomas may develop as a result of cochlear implant surgery. Primarily acquired cholesteatoma is not typically associated with congenital sensorineural hearing loss or cochlear implant in children.

Influence of Morphine on Pharmacokinetics and Pharmacodynamics of Ticagrelor in Patients with Acute Myocardial Infarction (IMPRESSION): study protocol for a randomized controlled trial.

Background: Ticagrelor is an oral platelet P2Y12 receptor antagonist which is recommended for patients suffering from myocardial infarction, both with and without persistent ST segment elevation. Morphine is the first choice drug in pain alleviation in the same clinical subset. Recently a possible negative influence of morphine on the pharmacokinetics and antiplatelet effects of P2Y12 receptor blockers has been postulated.

Long term results of childhood dysphonia treatment.

Objective: The aim of this study was to assess the long term results of treatment and rehabilitation of childhood dysphonia.

Methods: This study included a group of adolescents (n=29) aged from 15 to 20 who were treated due to pediatric hyperfunctional dysphonia and soft vocal fold nodules during their pre-mutational period (i.e.

The occurrence of molds in patients with chronic sinusitis.

Chronic rhinosinusitis (CRS) is a common inflammatory condition of nasal and paranasal sinus mucosa. Although pathogenic bacteria were postulated as main etiological factor responsible for most cases of CRS, the involvement of molds was recently proved in some cases. The aim of the study was to conduct mycological analysis of material obtained from patients operated on due to chronic sinusitis.

[Oral allergy syndrome--problem].

History of oral allergy syndrome goes back to 1987 year, when Amlot for the first time used this name for pollen-food cross-reactive reactions. Since that time many kinds of various reactions between pollens and different food had been described. Is seems that after almost 20 years the knowledge about this highly prevalent phenomenon is still incomplete and not well known among specialist other than allergologists.

[Inverted papilloma of the nose in patient after skin face transplantation].

Introduction: We discuss a case of 65 year old men with inverted papilloma of the right nose cavity. During childhood he had an operation of skin face transplantation prior to face haemangioma. He has no medical documentation from that time.

[Estimation of smell sense rehabilitation in patients after total laryngectomy].

The loss of sense of smell significantly decreases a quality of life after total laryngectomy. That is why this problem should be considered within a complex rehabilitation of laryngectomized patients. The smell exercises ought to start parallely to the speech rehabilitation.

[Septic thrombosis of the cavernous sinus complicated by intracerebral hemorrhage].

A case of septic cavernous sinus thrombosis in 41 year old men is described. One week prior to hospitalisation he had an influenza infection. During influenza nose furunculus, labial herpes and viral left otitis media with facial nerve paresis occurred.

[Lateral branchial cyst--case report].

A case report of big lateral branchial cyst growing for 25 years is described. The diagnosis was based on ultrasonography with aspiration biopsy, computed tomography and histopathological findings. Successful surgical treatment was performed.

[The use of CO2 laser in the treatment of leukoplakia of the oral cavity].

During the period from 1992 to 1996 in the Otolaryngological Clinic of the Medical Academy in Bydgoszcz 20 patients with leucoplakia of the oral cavity were hospitalized.
