Opis:
Salivary gland neoplasms represent about 3% of head and neck tumors. The area most affected by tumors is parotid salivary gland (standing for about 80% of all cases). The most common type of the neoplasm is pleomorphic adenoma (which accounts for 80-90% of all diagnoses). One of the rare diagnoses in this region comprises synovial sarcoma, as it mainly occurs in lower extremities. In head and neck region it accounts for about 3% of all diagnoses. About 20 cases have been described in this region, so far. The etiology of the disease remains unknown, but there are reports linking synovial sarcoma with the rearrangement in the gene responsible for chromosomal transcription t(X;18) (p11,q11).

Opis:
Introduction. Labial salivary gland biopsy is used for diagnosis of Sjögren’s syndrome (SS) and lymphoma accompanying SS. Aim. The aim of this study was to present the main techniques used for taking labial salivary gland biopsies in the diagnosis of SS with respect to their advantages, histologic criteria, validation, complications, and their usefulness for diagnostic procedures, monitoring disease progression, and treatment evaluation. Material and methods. This study is based on analysis of literature. Results. The microscopic confirmation of SS is based on the presence of focal lymphocytic sialadenitis (FLS) with a focus score ≥1 per 4 mm2 of glandular tissue. A lymphocytic focus is defined as a dense aggregate of 50 or more lymphocytes adjacent to normal-appearing mucous acini in salivary gland lobules that lacked ductal dilatation. Other histopathological features of SS are lymphoepithelial lesions and a relative decrease of <70% IgA + plasma cells. Labial salivary gland biopsy is characterized by high specificity, a positive predictive value, and an average sensitivity of 79% in SS. Conclusion. It can be also valuable in diagnosing B-cell mucosa-associated lymphoid tissue (MALT) lymphomas but it is not recommended for the monitoring of SS progression and the effectiveness of the treatment. Persistent lower lip hypoesthesia is the most severe complication of labial salivary gland biopsy.

Opis:
Introduction: The paper aims to demonstrate the Clinic’s and own research in the treatment of major salivary gland tumors. Material and method: In the years 2013–2019, there were 95 salivary gland surgeries, including 45 performed in women (47.36%) aged between 24 and 82 and in 50 men (52.64%) aged 29 to 86. Diagnostics of major salivary glands included: patient history, otolaryngological examination, ultrasound and fine needle aspiration (BACC) (of tumor), laboratory tests (morphology, CRP) and computed tomography (CT) or magnetic resonance imaging (MRI) to accurately assess salivary glands, location of lesion and lymph nodes prior to elective surgery. Research results: In the analyzed material patients with major salivary gland tumors were most frequently operated on at the age of 61–70 (34.7%) and 51–60 years (23.2%). Most patients with tumors were hospitalized in the last 4 years between 2016–2019, which accounted for 77.8% of all operated cases. Among the operated lesions, benign neoplasms and tumors occurred in 93.7%, of which the most frequent findings in histopathological examination were Warthin tumor in 50.5%, and multiform adenoma in 26.3%. The remaining tumors and benign neoplasms constituted only 16.9% and were observed in isolated cases, including eosinophilic adenoma, lymphoepithelial cyst, myoepithelial adenoma, lipofibrosarcoma, congestive cyst, air cyst, tubular adenoma, basal cell carcinoma, cyst with squamous metaplasia features, vascular malformation. Malignant salivary gland tumors were found in 6.3%, including the following malignant tumors were revealed histopathologically: adenocarcinoma, mucoepidermal carcinoma, acinocellular carcinoma, epithelialmyoepithelial carcinoma, ductal carcinoma. Conclusions: The majority of operated salivary gland tumors were benign (93.7%), of which the most common histopathologically were: Warthin tumor (50.5%) and multiform adenoma (26.3%), while malignant tumors occurred in 6.3%. Tumors were localized mainly in the parotid gland in as many as 93.7% cases, of which the most common localization concerned the superficial lobe in 56.8%. The most frequent surgical technique used in the Clinic was extracapsular dissection of the tumor in 88.4%, and other methods were used rarely.

Opis:
Pleomorphic adenoma is benign tumor of the salivary glands. It is the most common neoplazm both major and minor salivary glands. Only in 1% of cases pleomorphic adenoma occur in the sinonasal cavities. The histopalogical wiew of pleomorphic adenomas originating from small salivary glands is different in higher cellularity and lower stromal component than those from major salivary glands. It is a benign tumor but it should be treated as a clinically uncertain. Malignant transformation of pleomorphic adenoma can occur in 2-10% of cases, The aim of this study was to present he case of 37-year-old patient with giant pleomorphic adenoma of the sinonasal cavities causing extensive destruction of sinuses and orbits walls.

Opis:
Introduction and aim. Violation in the salivary glands will inevitably cause changes in periodontium, and periodontitis can disrupt the functioning of the salivary glands. The purpose of the work is to evaluate changes in NO-synthase and arginase activities, pro- and antioxidant balance in rat salivary glands and soft periodontal tissues during administration of bacterial lipopolysaccharide (LPS) and water avoidance stress (WAS) modeling. Material and methods. The experiment was performed on 24 rats. The animals were divided into 4 groups: control, WAS, animals injected intraperitoneally with 0.4 μg/kg of bacterial LPS of Salmonella typhi, WAS+LPS. Results. Water avoidance stress led to decrease of inducible NO-synthase (iNOS) activity in salivary glands by 1.63 times, but decreased arginase activity by 1.15 times, superoxide production increased by 1.53 times, catalase activity decreased by 1.2 times, and malonic dialdehyde (MDA) increased by 1.19 times compared to the control. Lipopolysaccharide led to increase of constitutive NO-synthases (cNOS) activity in salivary glands by 1.48 times, but decreased arginase activity by 6.15 times, catalase activity increased by 2.6 times and superoxide dismutase activity decreased by 2.74 times, and MDA increased by 6.84 times compared to the control. Water avoidance stress + LPS in salivary glands led to decrease of cNOS and arginase activity by 1.09 and 1.19 times, respectively, superoxide production increased by 1.88 times, catalase and superoxide dismutase activity decreased by 1.06 times and 1.34 times, respectively, and MDA increased by 2.44 times compared to the control. Water avoidance stress led to increase of iNOS activity in periodontium by 1.44 times and arginase activity decreased by 1.37 times, superoxide production increased 1.32 times, catalase activity and superoxide dismutase activities decreased by 1.27 times and by 1.53 times, respectively, and MDA increased by 1.31 times compared to the control. Lipopolysaccharide led to increase of iNOS activity in the periodontium by 3.88 times, arginase activity decreased by 2.69 times, superoxide production increased 1.64 times, catalase activity increased by 4.32 times, and MDA increased by 4.51 times compared to the control. Water avoidance stress + LPS in periodontium led to increase of iNOS and cNOS activities by 1.95 times and 1.53, respectively, arginase activity decreased by 1.39 times, superoxide production increased 1.66 times, catalase activity increased by 1.11 times, and MDA increased by 1.53 times compared to the control. Conclusion. The combination of LPS and WAS leads to changes in NO production and oxidative stress in salivary glands and the periodontium.

Opis:
Virus-induced oral abnormalities, occurring especially in severe COVID-19 cases of hospitalized patients, have various characteristics and clinical features being, either directly or indirectly, related to SARS-CoV-2 infection. Deregulation of the immune system as a result of SARS-CoV-2 infection may lead to the impairment of the normal defense pathway in the SARS-CoV-2 positive patients. This scoping mini-review is aimed to critically appraise the existing evidence concerning the potential link between COVID-19 condition and abnormal manifestations within oral cavity, affecting oral mucosa, salivary glands and sensory elements. COVID-induced oral mucosa manifestations, with various clinical aspects, are likely to occur as coinfections and secondary symptoms, as immune system imbalance is per se a causative factor of secondary manifestations. Oral mucosal lesions related to SARS-CoV-2 infection do not seem to demonstrate gender predilection, with the average reported age around 50 years of age. They include mainly white and erythematous plaques, ulcers, blisters, petechiae. The affected intraoral areas were mainly: tongue, palate, lips, gingiva, and buccal mucosa. The “aggressive” therapies utilized to treat COVID-19, including drug interactions may aggravate or initiate OMLs pathologies. Neglected oral hygiene or partial or complete abandonment of oral hygiene during intensive hospitalization constitutes an independent factor promoting a wide range of oral pathologies. In addition, stress factor indirectly impairs functioning of the immune system. Oral mucosa lesions occurring in COVID-19 cases present with a wide variation of non-characteristic features. These intraoral, soft tissues abnormalities seem to be reversible and transient. A potential impact of severe oral pathologies to systemic health resulting from SARS-CoV-2 infection, along with associated poor oral hygiene should not be ignored, predominantly in seriously ill patients hospitalized in intensive care units.

Opis:
Work in cadmium (Cd) smelter and smoking cigarettes damages teeth and oral mucosa which are protected by tissue and salivary glycoconjugates: glycoproteins, glycolipids, and proteoglycans. We worked out a rat model imitating human "environmental" and "occupational" exposure to cadmium using 5 mg Cd and 50 mg Cd/l in drinking water, respectively. In submandibulary glands of exposed to Cd rats, we found the time and dose dependent accumulation of Cd and simultanous decrease in activity of β-N-acetylhexosaminidase (HEX). In homogenates of submandibulary glands of control rats, β-N-acetylhexosaminidase showed the highest activity. The activities of α;-mannosidase and β-galactosidase were very low. None of these exoglycosidases were inhibited by Cd even at 44 mM concentration.

Aim: Epidemiological and clinical analysis of lymphoid tissue neoplasms in the neck region over a 15-year period. Material: There was performed retrospective analysis of 97 patients, aged 17 to 88 years, mean age of 60.3 years. The analysis included data from subjective study, physical examination, image and histopathological studies Results: Almost all cases were lymphoid neoplasms - 95 patients (98%). B cell lymphoma was the most commonly diagnosed lymphoma – 74 cases (76%), followed by Hodgkin's lymphoma- 19 cases (20%). Only two patients had T-cell lymphoma (2%). There was observed prevalence among women, K: M ratio for the whole group was 51: 46, while male predominance was reported in Hodgkin's lymphoma patients (K: M = 7: 12). Over the 15-year period, there was an increase in the number of lymphoid tumors. The most common location on the neck were lymph nodes - 71 (73.2%). Extranodal localizations (26.8%) were most often associated with salivary glands: parotid and submandibular involvement and with the dominant lymphoma of the marginal zone MALT (14 cases). In 57% of patients the fine needle aspiration biopsy (FNAB) results were false, with positive results only in 32% of patients. Conclusions: Tumors from lymphoid tissue in the neck region are most commonly B-cell lymphomas or Hodgkin,s lymphomas. Non-specific clinical signs and non-specific radiological images, as well as non-diagnostic results o FNAB, make it difficult to effectively differentiate lymphomas with cancer metastasis in neck lymph nodes. Histopathology results of the excised lymph nodes remains a standard for lymphoma diagnosis.

Opis:
Sjögren’s syndrome is an autoimmune exocrinopathy which manifests itself with dryness of the eyes and the oral cavity. These symptoms comprise a so-called sicca syndrome (xerostomia and xerophthalmia). Two forms of this disease may be distinguished: primary Sjögren’s syndrome which affects salivary glands and secondary Sjögren’s syndrome with other autoimmune diseases present such as rheumatoid arthritis, systemic lupus erythematosus or systemic scleroderma. The diagnosis is based on the classification criteria established in 2002 by a group of American and European scientists (American-European Consensus Group), which involve the interview and physical examination as well as serological, histopathological and radiological tests. Most of these examinations show some limitations such as invasiveness, expensiveness or limited accessibility. The latest research suggests that ultrasound examination may appear promising in the diagnostics of the main salivary glands: submandibular and parotid glands. It is an accessible and relatively cheap examination with high sensitivity and specificity values which are comparable to those obtained via conventional means used in the diagnostics of this disease, i.e. biopsy of the minor salivary glands, sialography and scintigraphy, as well as superior to those obtained in sialometry and Schirmer’s test. Additionally, ultrasonography correlates with the results of magnetic resonance imaging. Therefore, a number of authors claim that US examination should be included in the classification criteria of Sjögren’s syndrome. The aim of this article is to present the diagnostic capacity of the US examination in Sjögren’s syndrome using the current ultrasound classification systems based on the grey-scale, Doppler and contrast-enhanced examinations. The latest research confirms that the most valuable diagnostic criterion in Sjögren’s syndrome is the heterogeneity of the glandular parenchyma. The outcome of the examination greatly depends on the examiner’s experience.
Zespół Sjögrena jest autoimmunologiczną egzokrynopatią, manifestującą się objawami suchości oka i jamy ustnej, składającymi się na tzw. zespół suchości (kserostomia i kseroftalmia). Można wyróżnić dwie postaci choroby: pierwotny zespół Sjögrena, zajmujący głównie gruczoły ślinowe, oraz wtórny zespół Sjögrena, z towarzyszącymi innymi chorobami autoimmunologicznymi, tj. reumatoidalnym zapaleniem stawów, toczniem układowym rumieniowym czy twardziną układową. Rozpoznanie choroby opiera się na kryteriach klasyfikacyjnych opracowanych w 2002 roku przez grupę naukowców z Ameryki i Europy (American‑European Consensus Group), które bazują na badaniach przedmiotowych i podmiotowych, serologicznych, histopatologicznych i radiologicznych. Większość tych badań wykazuje pewne ograniczenia, takie jak inwazyjność, wysoki koszt czy mała dostępność. Ostatnie prace wskazują, że obiecującą metodą w diagnostyce choroby jest badanie ultrasonograficzne głównych gruczołów ślinowych: ślinianek podżuchwowych i przyusznych. Jest to badanie dostępne, stosunkowo niedrogie, wykazujące wysoką czułość i swoistość, na poziomie porównywalnym do konwencjonalnych metod stosowanych w rozpoznawaniu tej choroby, tj. biopsji gruczołów ślinowych mniejszych, sialografii i scyntygrafii, i przewyższającym sialometrię i test Schirmera. Dodatkowo koreluje z wynikami rezonansu magnetycznego. Wielu autorów postuluje zatem włączenie badania ultrasonograficznego do kryteriów klasyfikacyjnych zespołu Sjögrena. Celem pracy jest przedstawienie możliwości diagnostycznych badania ultrasonograficznego w rozpoznawaniu zespołu Sjögrena, z uwzględnieniem dotychczas stosowanych ultrasonograficznych systemów klasyfikacyjnych, opierających się na badaniu w skali szarości, w opcji dopplerowskiej oraz z zastosowaniem środków kontrastujących. Najnowsze badania potwierdzają, że najcenniejszym diagnostycznie kryterium w rozpoznawaniu zespołu Sjögrena jest niejednorodność miąższu gruczołów. Wynik badania w dużej mierze zależy od doświadczenia badającego.
