Inflammatory and nasal-sinus tumor pathology is a field of great interest in rhinology worldwide. The aim of the paper is to determine the prevalence of nasal and nasal-sinus inflammatory diseases, as well as nasal and nasosinusal rhinosinusitis tumors, in association or not with inflammatory diseases, using histopathological (HP) examination. It is also desired to identify the association of chronic inflammatory pathology with the tumor one, considering inflammation and immunodeficiency as local susceptibility factors. A retrospective study was performed on a group of 254 patients hospitalized between 2018-2019 in Department of Otorhinolaryngology, Emergency County Hospital, Târgu Mureş, Romania. Based on the clinical and HP examination, the distribution by inflammatory pathologies was made as follows 175 nasal polyposis, 108 chronic rhinitis, 39 sinusitis - strictly affecting the sinus and 28 chronic polyposis rhinosinusitis - nasal and sinus association. Considering the evaluation of the incidence of benign tumor pathology, the following were found out of the total examined cases, 4% squamous papilloma, 4% exophytic papilloma, 44% Schneiderian papilloma, 4% benign fibrous histiocytoma, 18% hemangioma, 4% hamartoma, and 4% osteoma were identified. The incidence of malignant tumors is 26% squamous cell carcinoma, 12% intestinal adenocarcinoma, 2% nonintestinal type adenocarcinoma, 2% large B-cell lymphoma, 2% plasma cell, 2% olfactory neuroblastoma, 7% malignant melanoma, 16% basal cell carcinoma. The paper draws attention to the increased incidence of tumor and inflammatory pathology both individually and in combination, considering the involvement of the clinical correlation with the HP result completed, if necessary, with immunohistochemical examinations, for a precise diagnosis.The fixed orthodontic measures taken induce significant stress to the gingival growth process during arch wire maneuvers of aligning and leveling. We observed, for a period of one to four years, fixed orthodontic devices in 80 human subjects. From these, we selected 44 subjects (22 women and 22 men) where the inflammatory process exhibited following the orthodontic fixed treatment, and with vacuum-formed orthodontic retainers (VFR) succeeding to fixed treatment. Samples were collected from each patient and histological and immunohistochemical (IHC) methodology was made to analyze the cytoarchitecture. Statistics were made after one-way analysis of variance (ANOVA), with the Bonferroni's correction. The IHC examination performed in the early stage revealed the presence in the inflammatory infiltrate of CD8-type T-lymphocytes, and of dendritic cells in large numbers. The examination performed in the late stage revealed the presence in the inflammatory infiltrate of CD20-type B-lymphocytes, which are mature cells capable of immunoglobulin synthesis, their activation being an important step in the maturation of the antibody response. The stress generated by arch wires in both genders was significantly higher than in the case of VFR. This observation was pointed out also by the cytohistological investigation outcome but was also based on an original scale conceived by our research team, following gingival hyperplasia evaluation. Also, with statistical significance, the comparative obtained values for men (p=0.01) and for women (p=0.001) illustrate clinical observations, allowing to affirm that, in our case, men were more stressed in bearing arch wire devices (AWD) and VFR, in comparison with women.Diagnostic and treatment plans in cystic jawbone tumors are often difficult to address. The etiopathogenic links involved in cell-matrix differentiation disorders are complex. Quantification of the inflammatory process in the evolution of cystic odontogenic lesions highlights a particular reactivity of the host, especially age-dependent and the endodontic-periodontal space interrelation, drawing attention to the difficulties of etiopathogenic, evolution, prognostic and treatment of these lesions. Difficulties in histopathological (HP) diagnosis are reported by the lack of morphofunctional integration of dental tissues, both topographically and evolutionarily, especially when odontogenic epithelial remains in the cystic wall, reactive bone condition, appearance and condition of the reactive epithelium are overlooked. In this study, we developed an interdisciplinary approach for the dynamics of tissue morphology found in the walls of maxillary cysts. Failure to recognize the tissues that form the cystic lesion leads to misinterpretations of pathology and to the wrong classification in the group of maxillary cysts. We analyzed by different techniques 564 biopsy fragments from maxillary cystic lesions, most of which are clinically classified as inflammatory or odontogenic ones. From our experience, we reevaluated the lesions with cystic changes and completed the diagnosis in 10-12% of cases. The most common maxillary cystic lesion encountered by us was the root cyst, an inflammatory dental cyst, which has been over diagnosed clinically, radiologically and histopathologically. Recognition and selection of embryonic remnants from odontogenesis is crucial for the HP diagnosis of maxillary cysts, allowing the clinician to monitor treatment or to develop evolutionary-prognostic perspectives of odontogenic cystic lesions.Oral cancer remains an important global health issue and despite recent diagnostic and therapeutic advances, it continues to have an unfavorable prognostic and decreased survival. Although palatal tumors represent one of the rarest locations of oral squamous cell carcinomas (SCCs), they are among the most aggressive local tumors, leaving behind important morpho-functional disabilities. In order to explain such local aggressiveness, the present study aims to investigate the immunohistochemical expression in palate SCCs of some markers known to be involved in the process of tumor invasiveness, such as Wiskott-Aldrich syndrome like (WASL), Claudin-1 (CLDN1), Integrin beta-6 (ITGB6) and c-Mesenchymal to epithelial transition protein (c-Met). We have found here a higher tumor WASL and CLDN1 reactivity in well-differentiated (G1) palate SCCs, and regardless the histological type, degree of differentiation or tumor topography, an overexpression at the invasion front, and in those palate' SCC cases with muscular invasiveness and with lymph node (LN) dissemination. ITGB6 and c-Met had a higher reactivity in moderately differentiated (G2) palate SCCs, especially at the periphery of tumor proliferations, at the invasion front and in those high invasive cases and as well as in those that associated LN dissemination. All four investigated markers were also positive at the level of LN metastatic proliferations. None of the markers could statistically stratify on age group and pain, and on bone and perineural invasion while all of them statistically stratified on survival and grading. We concluded that these markers have a prognostic role allowing the identification of those cases with an unfavorable clinical evolution and decreased survival.Femoral head osteonecrosis, also known as avascular necrosis, is a disease with a multifactorial etiology, characterized by a profound change of bone architecture, which leads to the diminishing of bone resistance and femoral head collapse. selleck chemical The main causes that lead to femoral head necrosis are represented by the decrease of local blood perfusion and increase of intraosseous pressure, because of an excessive development of adipose tissue in the areolas of the trabecular bone tissue in the femoral head. The histopathological and immunohistochemical (IHC) study performed by us showed that most of bone trabeculae were damaged by necrotic-involutive processes, their sizes being reduced, both regarding their length and their diameter; generally, the spans were thin, fragmented, distanced among them, which led to the occurrence of some large areolar cavities, full of conjunctive tissue, rich in adipocytes. Some of the residual bone spans even presented microfractures. In the structure of the trabecular bone tissue,the sclerous conjunctive tissue. Of the inflammatory cells present in the spongy bone tissue of the femoral head affected by osteonecrosis, the most numerous ones were the macrophages. Both macrophages and T- and B-lymphocytes had a heterogenous distribution.
The identification of biocomposites that improve cell adhesion and reduce bone integration time is a great challenge for implantology and bone reconstruction.

Our aim was to evaluate a new method of chemisorption deposition (CD) for improving the biointegration of hydroxyapatite-coated titanium (HApTi) implants. CD method was used to prepare a calcium fructoborate (CaFb) coating on a HApTi (HApTiCaFb) implant followed by evaluation of histological features related to bone healing at the interface of a bioceramic material in an animal model.

The coating composition was investigated by high-performance thin-layer chromatography/mass spectrometry. The surface morphology of the coating was studied by scanning electron microscopy (SEM), before and after the in vitro study. We implanted two types of bioceramic cylinders, HApTi and HApTiCaFb, in the femur of 10 New Zealand White (NZW) rabbits.

The release of CaFb from HApTiCaFb occurred rapidly within the first three days after phosphate-buffered saline immersion; there was then a linear release for up to 14 days. SEM analysis showed similar morphology and particle size diameter for both implants. Around the porous HApTiCaFb implant, fibrosis and inflammation were not highlighted.

Easily applied using CD method, CaFb coatings promote HApTi implant osseointegration in the femur of NZW rabbits.

The objective of this retrospective study, carried out between April and December 2019, was to identify the correlations of the known lithogenic factors with the chemical structure of the calculi in the patients from the North-Eastern region of Romania. The results obtained after the data analysis of our LAMPA questionnaire (L - liquids, A - antecedents, M - medication, P - associated pathologies, A - aliments) made in evidence a statistically relevant relationship between the heredocollateral history of lithiasis and calcium oxalate dihydrate (COD) calculi, hypertension and calcium oxalate monohydrate (COM) stones, uric lithiasis and diabetes, COD, and obesity, between predominantly uric lithiasis and meat or meat-derived products consumption, between frequent potato consumption and COD stones and the frequently consume of dairy products and predominantly COM calculi. The authors concluded that the use of a complex questionnaire, like LAMPA, together with Fourier-transform infrared (FTIR) spectroscopic and morphological analysis are essential steps for developing an efficient metaphylaxis.Basal cell carcinoma (BCC) is the most frequent human malignancy and at the same time the most frequent periocular malignancy, representing almost 80% of all non-melanoma skin cancers and 90% of eyelid cancers. The study included 50 cases of eyelid BCC, out of which 41 were nodular BCC (NBCC) and nine were infiltrative BCC (IBCC), with various Breslow scores (BS) and primary tumor (pT) category. We analyzed the immunoexpression of matrix metalloproteinases (MMPs) 1 and 13 in the tumoral epithelial component (TEC) and inflammatory stromal component (ISC) of BCC in relation to the two histopathological parameters. The immunoreaction for MMP-1 was identified in 41 (82%) cases and for MMP-13 in 46 (92%) cases both in the TEC and ISC of both types of BCC. The statistical analysis revealed that both collagenases had positive/high scores significantly associated with advanced BS. For MMP-1, there were statistical associations in TEC related to IBCC and high pT category, while MMP-13 only revealed statistical association in ISC with high pT.
