A retrospective analysis was performed of 12,888 cases of larynx and hypopharynx carcinoma diagnosed in 19 ENT Departments in Poland during an 11-year period from 1991 to 2001. An assessment of basic epidemiological data, including also tumor site and disease stage at the time of diagnosis, was conducted. Epidemiological trends over the 11-year period of the analysis were examined. The average M:F proportion was 8:1, with a significant increase in the number of female patients during the analyzed period. The predominant localization of carcinoma was in the glottis (47.2%), followed by the supraglottis (40.3%) and pyriform sinus (7.8%). A significant increase in pyriform sinus tumors was observed in the analyzed period. Majority of cases (57.4%) presented with local advanced stage (T3+T4) carcinoma of the larynx and hypopharynx, with the highest rate (81.0%) for the pyriform sinus carcinomas, and with the lowest rate for glottic tumors (41.8%). Regional lymph node metastases were diagnosed in 47.7% of the analyzed cases, with the highest rate (82.2%) in cases of pyriform sinus carcinomas, and the lowest (31.7%) in glottic carcinomas. In the 11-year period, a significant drop in N0 cases and a tendency toward increased rates of N2 and N3 lymph nodes metastases cases of supraglottic carcinoma were observed. Distant metastases at the time of diagnosis were registered in 2.2% of the analyzed cases, with the highest percentage in the posterior pharyngeal wall (7.6%) and pyriform sinus (7.4%) carcinomas.

The treatment of oral and maxillofacial infections is based on a recognized algorithm that may require modification under the influence of various local and systemic factors. The aim of this study was to present a comprehensive and microbiological profile of oral and maxillofacial infections, and explore possible correlations between the course of an infection and selected systemic factors based on the medical records of 329 patients affected by the disease. We identified most common clinical, demographic, bacterial, and laboratory parameters specific for these infections. There were statistically significant differences in Erythrocyte Sedimentation Rate, number of accompanying diseases, otalgia, dyspnea, and speech difficulties occurrence and neck space involvement between diabetic and non-diabetic patients. The duration of hospitalization and accompanying diseases correlated positively with the patient age and white blood cell count, and C-reactive protein value negatively correlated with age. The primary cause of infections, age, and comorbid diseases can modify the infection course and increase the risk of developing serious complications. It confirms the need for effective and targeted bacterial treatment in the early stages of infections. Age and general diseases are the most important systemic factors determining the infection symptoms and laboratory parameters assessing the severity of the inflammatory process.

Lip enlargement may be an important symptom of either systemic or local diseases. On the basis of selected age-matched clinical cases we present the possible causes of lip swelling. We describe the most representative symptoms and recommend treatment of these pathologies. We differentiate lip swelling in Miescher syndrome, monosymptomatic form of Melkersson-Rosenthal syndrome, lip swelling in erythema multiforme and Stevens-Johnson syndrome and lip hemangioma and mucous extravasation cyst. We compare different causes of lip edema and indicate the most helpful diagnostic and treatment methods.

(1) The SNM present as a very heterogeneous group of tumors. (2) The most common SNM are a Squamous cell carcinoma, and malignant lymphoma. (3) The majority of SNM are diagnosed at then advanced stage of local disease. (4) The calculated probability of 3-years survival was 64.0%, and 5-years survival 45.0%. (5) The diagnostic, as well as therapeutic approach to SNM requires a multidisciplinary cooperation.

According to a new concept for the classification and division of autoimmune diseases, Mikulicz's disease and Küttner's tumor belong to immunoglobulin G4-related diseases (IgG4-RD) and fulfil their diagnostic criteria. The aim of this study was to summarize the new classification concepts of IgG4-RD in the head and neck area and to review their clinical, histopathological and serologic criteria and the methods used in the diagnostic workup with respect to their advantages, limitations and differentiative value. The PubMed, Web of Science, Google Scholar, and Scopus databases were searched for articles published between 2009 and 2019 using the following key words: IgG4-related diseases, Mikulicz's disease, Küttner's tumor, salivary glands, xerostomia. Results of the review of the literature revealed that Mikulicz's disease and Küttner's tumor fulfil the same diagnostic criteria but may manifest different clinical symptoms which determine the choice of the different diagnostic tools.
