Opis:
The work deals with the mechanical properties and biological behaviour of composite materials made of polyether ether ketone (PEEK) polymer and carbon fibers (CF) designed for laryngeal biomaterials. Two types of PEEK–based matrix composites containing carbon fibers in the form of cloth (2D) and short fibers (MD) were made. The composite samples were obtained via hot mol-ding of PEEK/CF prepregs. Mechanical durability of the composite samples aging in Ringer’s solution at 37oC was analyzed. The samples were dynami-cally loaded under bending force up to 106 cycles. The ultrasonic wave propagation method was applied to study changes in the composites. The mechanical changes were analyzed, taking into consideration the anisotropic structure of the composite samples. The layered composite samples were modified with multiwalled carbon nanotubes (CNTs). The changes in mechanical stability of the composite samples were not significant after fatigue testing up to 1·106cycles. The biological tests were carried out in the presence of hFOB-1.19-line human osteoblasts and HS-5-line human fibroblasts. The level of type I collagen produced from both types of cells was determined by ELISA test. The tests showed differen-ces between the samples with regard to the viability of the cells.

ObjectivesVestibular rehabilitation leads to a gradual diminution of the subjective and objective symptoms that accompany the vestibular disorders. The aim of the study was to compare the impact of 2 different types of vestibular rehabilitation on vestibular compensation in patients with chronic unilateral vestibular dysfunction.Material and MethodsThe study was conducted on a group of 58 subjects (43 females and 15 males) aged 40–64 years, who presented with chronic unilateral vestibular dysfunction and were hospitalized. The patients were randomly assigned to either of the 2 groups established. The study was conducted in a 6-week period. Group 1 consisted of patients who underwent customized group vestibular rehabilitation in an outpatient setting. The program was performed once a week for 1 h 30 min, under the supervision of a physiotherapist and a physiatrist. Group 2 was instructed to perform Cawthorne–Cooksey exercises and simple balance exercises twice a day for 15 min.ResultsAn improvement in the outcomes of the Dynamic Gait Index as well as the Berg Balance Scale was statistically significant for group 1. The time for fulfilling the task in the Timed Up and Go Test improved in both groups (p < 0.05). The subjective estimation of the symptoms evaluated with the use of the Dizziness Handicap Inventory and the Visual Analogue Scale revealed a statistically significant improvement in both groups, yet it was higher in group 1.ConclusionsThe compensation achieved after 6 weeks of the customized, supervised outpatient rehabilitation program in group 1 was superior to the results of the home-based unsupervised Cawthorne–Cooksey and balance exercises.

Opis:
Squamous cell carcinoma is the most common malignant neoplasm of the larynx. However, there are other rare malignancies that are reported by worldwide literature, such as neuroendocrine tumors, mesenchymal sarcomas, malignant salivary tumors, adenocarcinomas, lymphoepitheliomas, plasmocytomas and non-Hodgkin lymphomas. The authors present several cases of rare laryngeal neoplasms with a particular consideration of their origin, histopathological characteristics and methods of treatment. They emphasize the necessity of careful diagnosis in case of laryngeal tumors with respect to patomorphological examination.

Opis:
Currently, 3D printing in medicine does not comprise only prostheses or implants, but also medical modelling and surgical planning. The future of 3D printing is printing combined with tissue bioengineering (bioprinting). Scaffolds made in 3D technology containing living cells are a step to creating tissues and organs. Three-dimensional printing in surgery is now considered the future of reconstructive and regenerative medicine. Head and neck surgery also benefits from advances in 3D printing. In this article, we will describe some of the possibilities offered by 3D printing in the aspect of education, training, and printed prostheses for the needs of head and neck surgery.
Obecnie druk 3D w medycynie oznacza nie tylko protezy czy implanty, ale także modelowanie medyczne i planowanie chirurgiczne. Przyszłością będzie druk 3D połączony z bioinżynierią tkankową (bioprinting). Rusztowania wykonane w technologii 3D zawierające żywe komórki są krokiem do tworzenia tkanek i narządów. Druk trójwymiarowy w chirurgii uważany jest obecnie za przyszłość medycyny rekonstrukcyjnej i regeneracyjnej, a z dokonań na tym polu korzysta także chirurgia głowy i szyi. W prezentowanym artykule opiszemy niektóre możliwości, jakie daje druk 3D w aspekcie edukacji, szkoleń oraz drukowanych protez na potrzeby chirurgii głowy i szyi.

Opis:
Life sciences, a field closely intertwined with human biology and physiology, employ various research methods, including morphology studies and quantitative analysis through non-destructive techniques. Biological specimens often consist of three-phase structures, characterized by the presence of gas, liquid, and solid components. This becomes crucial when the chosen research methodology requires the removal of water from samples or their transfer to a cryostat. In the current research, mechanical and topographical examination of cartilage was performed. The materials were generously provided by the Department of Anatomy at the Medical University of Silesia, thereby eliminating any concerns regarding their origin or ethical use for scientific purposes. Our research methodology involved the application of atomic force microscopy (AFM), which minimally disrupts the internal equilibrium among the aforementioned phases. Cartilage, recognized as a ‘universal support material’ in animals, proves to be highly amenable to AFM research, enabling the surface scanning of the examined material. The quantitative results obtained facilitate an assessment of the internal structure and differentiation of cartilage based on its anatomical location (e.g., joints or ears). Direct images acquired during the examination offer insights into the internal structure of cartilage tissue, revealing morphological disparities and variations in intercellular spaces. The scans obtained during the measurements have unveiled substantial distinctions, particularly in the intercellular ‘essence’, characterized by granularities with a diameter of approximately 0.5 μm in ear cartilage and structural elements in articular cartilage measuring about 0.05 μm. Thus, AFM can be a valuable cognitive tool for observing biological samples in the biological sciences, particularly in medicine (e.g. clinical science).
