Oral Health of Patients Treated with Acrylic Partial Dentures Using a Toothpaste Containing Bee Product

This study was carried out to investigate the influence of a propolis and tee tree oil-containing hygienic agent on selected oral health parameters, oral microflora, and the condition of periodontal health. Thirty-seven patients who underwent oral rehabilitation with a removable acrylic denture were selected and randomly assigned into two groups: study group (A) which received a newly formulated propolis and tee tree oil-containing toothpaste or a control group (C) without an active ingredient. API, S-OHI, and mSBI were assessed in three subsequent stages. During each examination swabs were employed for microbiological inoculation: in the study group after 4 weeks use of the active toothpaste showed a decrease in the number of isolated microorganisms. In the control group, after 4 weeks use of the toothpaste without active ingredients resulted in increase in the number of the isolated microorganisms. Improvements in hygiene and the condition of periodontium were observed in patients using active toothpastes. In the study group the oral flora diversity was reduced by the decrease in the number of cultured microorganism species, while in the control group an increase in the number of cultured microorganisms and their species was observed

The suitability of CFD in diagnosis and treatment of laryngeal diseases

Computational Fluid Dynamics (CFD) is a fluid mechanics department that uses numerical methods to solve fluid flow issues. A review of the literature was done as well to summarize the usage of the CFD method in the assessment of airflow through the upper respiratory tract (GDO), especially in the larynx. CFD is now becoming a very useful tool not only for analyzing airflow patterns and mechanism of particle deposition in the larynx, but also for obtaining information on temperature, pressure and shear stress changes in GDO. It is a tool with which one can safely plan surgical treatment as well as predict its potential effects

Przydatność metody CFD w diagnostyce i leczeniu chorób krtani

Metoda komputerowej dynamiki płynów (Computational Fluid Dynamics; CFD) to dział mechaniki płynów wykorzystujący metody numeryczne do rozwiązywania zagadnień przepływu płynów. W niniejszej pracy dokonano przeglądu piśmiennictwa dotyczącego zastosowania metody CFD w ocenie przepływu powietrza przez górne drogi oddechowe (GDO), ze szczególnym uwzględnieniem krtani. Metoda ta staje się obecnie bardzo przydatnym narzędziem nie tylko do analizy schematów przepływu powietrza i mechanizmu osadzania się cząstek w krtani, ale także do uzyskania informacji dotyczących zmian temperatury, ciśnienia, naprężeń ścinających w GDO. Jest ona narzędziem, z użyciem którego można bezpiecznie zaplanować leczenie operacyjne, jak również przewidzieć jego potencjalne skutki

Ostre rozlane zapalenie ucha zewnętrznego

Diffuse acute otitis externa (OEAD) is one of the most frequent cases recorded in Otorhinolaryngological emergency room. The main symptoms include: acute otalgia, feeling of ear fullness, itching, hearing impairment, sometimes fever. Otoscopy is the basic part of the diagnosis. First-line treatment involves topical antibiotic eardrops with or without a steroid. Clinicians should prescribe a non-ototoxic preparation when the patient has a known or suspected perforation of the tympanic membrane. Systemic antibiotics should not be prescribed in the first stage of the therapy unless the patient is at risk of severe course of the disease.Ostre rozlane zapalenie ucha zewnętrznego (OEAD; otitis externa acuta diffusa) to jedna z częstszych przyczyn zgłaszania się pacjentów na ostry dyżur otorynolaryngologiczny. Głównymi dolegliwościami, o których informują chorzy, są: nagły ostry ból, uczucie pełności w uchu, często świąd, upośledzenie słuchu, czasami gorączka. Podstawą rozpoznania jest badanie otoskopowe. Leczenie pierwszego rzutu polega na podawaniu miejscowo kropli zawierających antybiotyk ze sterydem (np. cyprofloksacyna z fluocynolonem) lub bez (np. cyprofloksacyna). Jeżeli nie ma możliwości oceny ciągłości błony bębenkowej, należy unikać stosowania preparatów o potencjale ototoksycznym. Antybiotyki o działaniu systemowym nie powinny być przepisywane w pierwszej fazie leczenia zapalenia ucha zewnętrznego – chyba, że pacjent jest w grupie ryzyka wystąpienia zapalenia ucha zewnętrznego o ciężkim przebiegu

Risk Factors of Recurrence and Malignant Transformation of Sinonasal Inverted Papilloma

Sinonasal inverted papilloma is a relatively rare disease; however, it is prevalent enough for every ENT practitioner to encounter it several times throughout medical routines. Despite the developments in experimental and clinical medicine as well as surgical techniques, our knowledge of this disease is still inadequate. With improved imaging and better diagnostic techniques, proper diagnosis and qualification for surgical approaches leave no doubt. Although the endoscopic approach seems to be the gold standard for such condition, some cases may additionally require an external approach. Regardless of the type of surgery, postoperative management is crucial for both healing and long-term follow-up. Unfortunately, the procedures are still lacking in explicit and standardized postoperative management guidelines. Moreover, an important issue is still the need for a biomarker indicative of inverted papilloma and its malignant transformation. Several particles, within the spotlight of the researchers, have been SCCA, Ki-67, Bcl-2, Wnt proteins, and many more. Nevertheless, the topic requires further investigations

Analysis of the Effectiveness of Arytenoidectomy and Posterior Cordectomy with the Use of CFD Airflow Measurements in Patients with BVFP: A Retrospective Study

Purpose. Bilateral vocal fold paralysis (BVFP) is a rare larynx disease manifested by dyspnea, which often requires surgical treatment. The aim of the study is to determine the effectiveness of unilateral arytenoidectomy with posterior cordectomy in the treatment of BVFP using the computational fluid dynamics (CFD) method. Methods. This study included 33 patients with BVFP who underwent unilateral laser arytenoidectomy with posterior cordectomy. Glottis area measurements and spirometry, as well as a self-assessment of respiratory efficiency were performed before the surgery and after the recovery period. Using the CFD method, computer models of the glottis were made. Then, changes in air pressure gradient and maximum air velocity at the level of glottis were calculated, and local fields of pressure and air velocities were obtained. Results. The values of glottal surface area (S), spirometry parameters (forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF)), inlet air velocity at the glottal level as well as patients self-assessment of respiratory efficiency turned out to be significantly higher after the operation. The values of maximum velocity at the glottal level, pressure gradient at the glottal level turned out to be significantly lower after the surgery. We observed that the greater the increase in glottal surface area, the greater the decrease in self-assessment scales (visual analogue scale (VAS) and Medical Research Council (MRC)). Increased levels of spirometry parameters after the surgery correlated with smaller decrease of PEF-dependent pressure gradient at the glottal level (PEFΔPCFD). Conclusion. Unilateral laser arytenoidectomy with posterior cordectomy is an effective method for the treatment of BVFP. CFD is a useful tool to determine and visualize the effectiveness of surgical treatment in BVFP

The Influence of Toothpaste Containing Australian Melaleuca alternifolia Oil and Ethanolic Extract of Polish Propolis on Oral Hygiene and Microbiome in Patients Requiring Conservative Procedures

The study was based on the use of a toothpaste with antiphlogistic activity, containing Australian Melaleuca alternifolia oil (tea tree oil—TTO) and ethanolic extract of Polish propolis (EEP). Fifty-one patients with varying conditions of the gingiva were divided into two groups. The study group received the toothpaste with TTO and EEP, while the control group received the same toothpaste but without TTO and EEP. Approximal plaque index (API), simplified oral hygiene index (OHI-s) and modified sulcus bleeding index (mSBI) were assessed in three subsequent stages. During each examination, swabs were employed for microbiological inoculation. During the period of use of toothpastes with TTO and EEP, a significant reduction of the API was observed, as assessed upon the control visit after 7 days and after 28 days, compared to baseline. A statistically significant reduction of mSBI was observed after 7 and 28 days of using the toothpaste with TTO and EEP, as compared to the value upon the initial visit. Statistically significant differences in the OHI-s value were observed in the study group, which was using the active toothpaste. The use of a toothpaste containing TTO and EEP helps to maintain microbiome balance. The observed stabilisation of bacterial microflora confirms the beneficial activity of toothpaste containing EEP and TTO compared to the control group, where the lack of these substances contributed to the emergence of qualitative and quantitative changes in oral microbiome
