A proposal for a database of sounds generated by temporomandibular joints and a tool for automateddiagnosisbasedonanRDC/TMDquestionnaire.

The prevalence of TMD indicates a need to develop new tools that are useful in the case of screening examinations. These methods can support diagnosis at the early stage of the disorder. The purpose of this research was to develop a comprehensive tool that would function as both a database of sounds generated by TMJ and as software which facilitates automated diagnosis.

New Methods for the Acoustic-Signal Segmentation of the Temporomandibular Joint.

(1) Background: The stethoscope is one of the main accessory tools in the diagnosis of temporomandibular joint disorders (TMD). However, the clinical auscultation of the masticatory system still lacks computer-aided support, which would decrease the time needed for each diagnosis. This can be achieved with digital signal processing and classification algorithms.

The role of endoscopic and demographic features in the diagnosis of gastric precancerous conditions.

Introduction: The diagnosis of atrophic gastritis (AG) and intestinal metaplasia (IM) is a crucial screening and surveillance strategy for gastric adenocarcinoma.

Objectives: The main objective was to assess the performance of endoscopic diagnosis of gastric precancerous conditions in a real‑life scenario.

Patients And Methods: A total of 2099 gastroscopies with biopsy to evaluate gastritis performed in 3 endoscopic centers from March 2018 to October 2019 were retrospectively analyzed.

The Concentration of CMKLR1 Expression on Clinicopathological Parameters of Colorectal Cancer: A Preliminary Study.

: Colorectal cancer (CRC) is the second-most common cause of cancer-related deaths worldwide. Angiogenesis is crucial for cancer growth, infiltration of surrounding tissues, and metastasis and plays a key role in the pathogenesis of CRC. Chemerin/chemokine-like receptor 1 (CMKLR1) is one of the biochemical pathways involved in the regulation of angiogenesis in solid tumors.

A Novel Method of Temporomandibular Joint Hypermobility Diagnosis Based on Signal Analysis.

Despite the temporomandibular joint (TMJ) being a well-known anatomical structure its diagnosis may become difficult because physiological sounds accompanying joint movement can falsely indicate pathological symptoms. One example of such a situation is temporomandibular joint hypermobility (TMJH), which still requires comprehensive study. The commonly used official research diagnostic criteria for temporomandibular disorders (RDC/TMD) does not support the recognition of TMJH.

Assessment of sheep knee joint after ACL replacement with Achilles tendon autograft and PLA-based implant.

In this study, we propose a new approach in the anterior cruciate ligament (ACL) replacement to provide stability and integration with bone tunnel. A polylactide (PLA)-based tubular implant was used to support the graft stabilization in femoral and tibial bones and to stimulate the healing process after (ACL) replacement on a sheep model. The ACL was replaced with an autologous Achilles tendon split graft.

Advanced Leiomyosarcoma of the Retroperitoneal Space in a Kidney Transplant Recipient with a History of Peritoneal Dialysis: A Case Report.

BACKGROUND Leiomyosarcoma frequently occurs in patients who are on immunosuppressive therapy. It is the second most common sarcoma in this population and is often associated with Epstein-Barr virus (EBV) infection. We present a case of advanced leiomyosarcoma of the retroperitoneal space in a kidney transplant recipient and discuss additional risk factors for oncogenesis.

Recurrence of melanoma in the scar after excised Spitz nevus in a 17-year-old child.

Melanoma in childhood is rare and its diagnosis is more difficult than in adults, as it often presents histologic features overlapping with the Spitz nevus. The authors report the case of a 17-year old boy who was first diagnosed with Spitz nevus, however, the final diagnosis made after the excision of the tumor arising in the scar was changed to melanoma. The case in this present study emphasizes the importance of the differential diagnosis of skin tumors in young patients.

Composite detection rate as an upper gastrointestinal endoscopy quality measure correlating with detection of neoplasia.

Background: Esophagogastroduodenoscopy (EGD) is commonly used diagnostic method with no widely accepted quality measure. We assessed quality indicator-composite detection rate (CDR)-consisting of detection of at least one of the following: cervical inlet patch, gastric polyp and post-ulcer duodenal bulb deformation. The aim of the study was to validate CDR according to detection rate of upper gastrointestinal neoplasms (UGN).

The expression profile of genes encoding tumor necrosis factor-alpha, interleukin-6 and their receptor in benign adrenal tumors.

In the process of neoplasia, during which benign adrenal tumors are formed, stimulators of new blood vessel growth as well as growth of tumor cells are cytokines, especially tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6). We analyzed the expression profile of genes coding: TNF-α, tumor necrosis factor receptor 1 (TNF-R1), TNF-R2, IL-6, interleukin 6 receptor (IL-6R) in sections of adrenocortical tumor tissue, rated on the Weiss point scale, in patients with clinically diagnosed Conn's and Cushing's syndrome, and the usefulness of determining the examined genes as markers differentiating individual clinical units. There was no correlation between the expression of the examined genes and clinical parameters such as age, BMI or blood pressure, both in the entire study group and in individual subgroups.

Leydig cell ovarian tumor - clinical case description and literature review.

Leydig cell ovarian tumors constitute not only a medical problem for clinicians but also a social problem - which is why women with symptoms of hirsutism relatively quickly contact physicians for medical consultation. Leydig cell ovarian tumor is a rare sex cord-gonadal stromal tumor which constitutes less than 0.5% of ovarian tumors.

The new method, the old problem - role of contrast-enhanced spectral mammography in the diagnosis of breast cancer among Polish women.

Purpose: The aim of the study was to evaluate spectral mammography (CESM) in diagnosing breast cancer, which is based on sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV).

Material And Methods: The study included a group of 547 women who underwent spectral mammography and histopathological verification of the lesion, previously seen in mammography and/or ultrasound. In the group of 547 women, 593 focal lesions were diagnosed.

Aggressive Angiomyxoma in an 11-Year-Old Boy - Diagnostic and Therapeutic Dilemmas: An Unusual Case Report and Review of the Literature.

Aggressive angiomyxoma (AAM) is a rare tumor with a high risk of local recurrence. Scrotal AAM mimics common pediatric pathologies including hernia or hydrocele. We present 11-year-old boy who underwent macroscopically radical excision of right scrotal AAM.

Omentin, vaspin and irisin in chronic liver diseases.

Omentin and vaspin are adipokines potentially considered in the development of liver pathology. Irisin is new myokin potentially participating in energy processes in the organisms. The aim of this study was to evaluate the plasma concentration of these cytokines and the relationships of them with selected parameters of laboratory tests and of histopathological changes in selected chronic liver diseases: non-alcoholic fatty liver diseases (NAFLD), primary biliary cholangitis (PBC) and alcoholic cirrhosis (AC).

Effects of Polylactide Copolymer Implants and Platelet-Rich Plasma on Bone Regeneration within a Large Calvarial Defect in Sheep.

The aim of this study was to verify whether L-lactide/DL-lactide copolymer 80/20 (PLDLLA) and platelet-rich plasma (PRP) trigger bone formation within critical-sized calvarial defects in adult sheep ( = 6). Two craniectomies, each ca. 3 cm in diameter, were created in each animal.

Protective Effect of Polyphenol-Rich Extract from Bee Pollen in a High-Fat Diet.

We have studied a preventive effect of polyphenol-rich bee pollen ethanol extract (EEP) against histological changes in the liver and cardiac blood vessels, abnormalities of lipid profile, and the levels of oxidized low density lipoproteins (ox-LDL), asymmetric dimethylarginine (ADMA), angiotensin-converting enzyme (ACE), and angiotensin II (ANG II) caused by a high-fat diet in CBL₆ mice. Supplementing the diet with EEP in the doses of 0.1 g/kg body mass (BM) and 1 g/kg BM resulted in a decrease of total cholesterol by 31% and 35%, respectively.

Serum interleukin‑17 levels predict inflammatory activity in patients with autoimmune hepatitis.

INTRODUCTION    The etiology of autoimmune hepatitis (AIH) is unclear, with molecular mimicry between host and viral/drug antigens being the most plausible mechanism initiating the immune cascade that induces hepatocyte injury. Finding a serologic parameter that closely relates to the liver histology would be beneficial for monitoring AIH activity and optimizing treatment. OBJECTIVES    We studied serum interleukin (IL)-17 levels and IL‑17 activators (IL‑6 and transforming growth factor β1 [TGF-β1]) in treatment-naive and immunosuppressed patients with AIH.

Vaspin mRNA levels in the liver of morbidly obese women with nonalcoholic fatty liver disease.

The aim of this study was to evaluate hepatic vaspin mRNA in morbidly obese women with nonalcoholic fatty liver disease (NAFLD) and to look for its relationships with metabolic and histopathological features. The study included 56 severely obese women who underwent intraoperative wedge liver biopsy during bariatric surgery. Hepatic vaspin mRNA was assessed by quantitative real-time PCR.

Hepatic chemerin mRNA in morbidly obese patients with nonalcoholic fatty liver disease.

The aim of this study was to investigate hepatic chemerin mRNA, serum chemerin concentration, and immunohistochemical staining for chemerin and and chemokine receptor-like 1 (CMKLR1) in hepatic tissue in 56 morbidly obese women with nonalcoholic fatty liver disease (NAFLD) and to search for a relationship with metabolic and histopathological features. Chemerin mRNA was assessed by quantitative real-time PCR, chemerin, and CMKLR1 immunohistochemical expression with specific antibodies, while serum chemerin concentration was assessed with commercially available enzyme-linked immunosorbent assays. Serum chemerin concentration reached 874.

Primary neuroendocrine carcinoma of the breast - a report of four cases.
