Introduction: Matrix metalloproteinases (MMPs) are key enzymes involved in degradation of extracellular colagen matrix during periodontal disease progression. The aim of our work was to study the levels of MMP-1, MMP-2, MMP-7, MMP-9 and MMP-10 in saliva of patients with chronic periodontitis. Materials and methods: The study included 22 patients with chronic periodontal disease and 15 controls. We collect unstimulated whole saliva from all volunteers included in the study. Salivary levels of mentioned MMPs were analyzed using magnetic bead-based multiplex assays and Luminex technology. Results: MMP-1, MMP-7, MMP-9 and MMP-10 present statistically increased salivary levels at patients with periodontal disease versus the control group (p<0.05). Salivary level of MMP-2 at patients with chronic periodontitis was increased but statistically insignificant compared with healthy subjects (p=0.1). Conclusions. The increased level of these enzymes in patients diagnosed with periodontal disease reflects their implication in periodontal tissue degradation. Saliva is an excellent fluid useful in monitoring the severity of this oral disease that affects about half of the adult population around the world.
"Background: Cardiovascular disease can be triggered and accelerated by hypertension and the underlying changes in the structure and function of arteries. The purpose of this review is to explore some vascular changes that occur in hypertension as a consequence of the imbalance between cell proliferation and cell death, processes that play an important role in stabilizing the thickness of the arterial wall during vascular remodeling. Methods: The authors conducted research through PubMed and Google Scholar databases using the following search formula: (hypertensive*) AND ((vascular modifications)) OR (vascular changes)) AND (cell death). Results: From 40 articles, only 17 publications were included in this study, taking into account four processes that can be preceded or followed by inflammation and depend on the interaction between local growth factors, vasoactive substances, and hemodynamic stimuli: Cell proliferation and growth; Cell migration; Cell death; Degradation or reorganization of extracellular matrix. Conclusions: To summarize, maladaptive vascular changes in hypertension can represent a major argument for prompt and maximal therapeutic intervention in patients with high cardiovascular risk. Moreover, they can represent an important step in discovering new markers of cardiovascular risk and in the development of new targeted therapies for different pathways of cellular signaling through which the reversibility of abnormal vascular changes could be obtained.

One of the most obvious trends in current prosthetic dentistry is the introduction of digital techniques. Of these, the techniques that offer the possibility of aesthetic prefiguration of the final prosthetic result are of particular interest to the dentist. The aim of this paper was to verify the applicability of the Digital Smile Design application, which is the most commonly, used aesthetic prefiguration application, an application designed for the dentate patient, to full edentulism. Two groups of full edentulous patients were formed: the first group, complete denture carriers, dissatisfied with the aesthetic aspects, that they wanted to improve in the new denture, and, the second group, newly bimaxillary full edentulous patients with high aesthetic expectations. Thus, on the first group, the tests were performed on the existing denture, and the second one with the maxillary occlusion template. However, the view of the final result offered the patients the chance to have a realistic picture of their desires regarding the shape, color, size of the teeth, which were inadequate in relation to age and facial typology. The use of this application also improves communication with the dental laboratory. In full edentulism, the current DSD technique can be used with some limitations and the use of it in this field needs more complex studies on larger groups of patients.
Aim. The assessment of distribution of supernumerary permanent teeth (SPT) and the disturbances caused by them. Material and method. Cross-sectional study upon a sample of 85 children (58 boys) aged between 3 and 18 years (mean age=9.08±3.09 years) with at least one SPT. Were analyzed: patients' distribution according to gender, age and number of dental units; SPT distribution according to arch and topography and also the disturbances noticed. Results. a) boys:girls ratio=2.14:1; b) the 85 patients had 107 SPT, mean number=1.25; c) 76.47% of patients had one SPT; d) 89.72% of SPT were on maxillary arch, maxilla:mandible ratio = 8.7:1; d) 92.52% of SPT were localized in anterior region, anterior:posterior region ratio = 12.3:1; e) mesiodens –71.96%, supernumerary lateral incisor – 19.62%; f) disturbances caused by SPT: ectopic eruption of permanent teeth – 36.47%; delay or failure of eruption of permanent teeth – 21.17%; crowding – 20%. Conclusions. 1. Supernumerary teeth were most frequent noticed in boys, in maxillary anterior region. 2. Most often they caused eruption disturbances of permanent teeth. Keywords: supernumerary permanent teeth, distribution, complications.
The aim of this study was to compare two computerized digital esthetic design methods (DSD and Visagismile) in order to properly choose the appropriate form of the maxillary frontal teeth for complete bimaxillary edentulous patients and to validate the use of these applications in complete edentulism. An online questionnaire was submitted to a group of 100 persons (dental doctors, dental medicine students and persons activating in other fields); the respective persons were requested to choose the form of maxillary frontal teeth for a group of four complete bimaxillary edentulous patients, whose esthetic design had been performed by using the two computerized progams. Following the respondents' analysis of the esthetic previews elaborated for the four patients 60% of the total answers were in favour of DSD while the remaining 40% were in favour of Visagismile; these percentages are identical with the ones obtained on the basis of the answers given by dental doctors and dental medicine students. In case of the respondents activating in other fields the percentages were 66% in favour of DSD and 34% in favour of Visagismile. Based on the results of the study the two computerized methods were validated also for cases of complete edentulism but further studies to confirm this validation are still required. These two methods improve the dental doctor/patient communication and certainly provide a higher predictability of the esthetic results of prosthetic restorations not only for dentate patients but also in cases of complete edentulism.
Unlike the therapy of primary BMS, the treatment of secondary BMS benefits, in addition to symptomatic therapy, from the possibility of using means and methods to correct biological disturbances and/or morphological, psycho-emotional changes respectively. The use of these therapeutic means in secondary BMS is recommended to be established as a first step of therapeutic conduct. Their success is reflected in homeostasis restoring, correcting morphological and functional changes of the field, which frequently leads to no longer use prescription of symptomatic treatment.
Aim. To identify the main facial features associated to facial attractiveness in women nowadays. Method. A descriptive study was conducted on a sample of 20 female public figures, very famous and successful women, most frequently actresses, singers or models, considered very beautiful nowadays. Their selection followed the analysis of several recent tops that aimed identifying most beautiful women, in which raters were lay persons. Data was collected by analyzing photos from frontal and lateral view, during rest position and smiling. Results. The persons analyzed registered diverse facial traits. Most obvious trends, encountered in more than 75% of them, included: Caucasian race; straight and long hair; average nasal tip protrusion; maxillary dental midline concordant to facial midline; a thicker lower lip compared to the upper lip; exposure of only maxillary incisors during smile; decreased or absent buccal corridor; maxillary central incisors of oval/rectangular shape; absence of maxillary teeth crowding. Other frequently encountered features were: American nationality; brown hair; eyes with medium size, almond shape, wide set, of green color; nose with an average width; face with a decreased lower third and a slightly convex profile; a thick lower lip and an average upper lip; exposure during smiling till the first molar, with a normal smile line. Conclusions. The public beautiful women nowadays register features that are generally associated to an increased facial attractiveness. Knowledge of trends in facial beauty is useful in dental practice, in order to understand better patient's need in terms of esthetic expectations.
According to literature the primary retroperitoneal malignant pathology is rare, representing less than 0.5% of all malignancies. In spite of its low incidence, this pathology often proves challenging in terms of diagnosis and treatment. The most com¬mon retroperitoneal malignancy is represented by lymphoma that accounts for approximately 33 % of the retroperitoneal malignancies. Other frequent retroperitoneal tumors are sarcomas: liposarcomas, leiomyosarcomas and malignant fibrous histiocytoma (in order of incidence). We have analyzed the existing data regarding the most common primary retroperitoneal tumors in order to realize a brief classification and their differential diagnosis considering their clinical, imagistic, histopathological and molecular characteristics. The technological developments that have been made over the years in terms of imaging investigations, as well as in biomelecular and cytogenetic studies have offered new possibilities for of assessing a retroperitoneal mass in order achieve more precise informations that can guide physicians to better distinguish between different types of retroperitoneal tumors and therefore their therapeutical protocol.
"The recent increase in life expectancy is the main argument for a better understanding of the pathophysiological mechanisms underlying aging. These, once known, can provide possible links to therapies to prevent aging or slow down the process. Normal aging is associated with a progressive decrease in the glomerular filtration rate. Accurate estimation of GFR in the elderly is under the suspicion of multiple errors mainly due to sarcopenia and decreased protein intake. Differentiation between chronic kidney disease and the physiological decline of GFR might be a challenge in clinical practice and this has consequences on the evolution and treatment of the numerous comorbidities of the elderly. The current trend to use non-invasive diagnostic techniques explains the need to identify a serological marker to help differentiate between decreased GFR secondary to kidney aging or the development of chronic kidney disease."
"Novel biotechnologies like brain banking pose a challenge in neurodegenerative diseases research, being not only a step towards a better understanding for these diseases, but also from a bioethical point of view. Brain banks collect tissue for research purposes from deceased persons suffering from neurodegenerative diseases such as Parkinson's or Alzheimes's disease. In order to improve the quality in this research field, confidentiality and a detailed informed consent are aspects that should be emphasized. Moreover, given the fact that the brain collecting takes place during an autopsy, legal aspects also play an important role, hence a legal frame is also needed. The role of the deceased's family should also be taken into account, especially when and how they can decide if the autopsy can be performed in the first place. The research participant should sign a detailed informed consent that must remain the research basis to which extent the collected data should be disclosed. Finally, only a framework of bioethical and legal norms can improve the quality of brain banking research. A comprehensive perspective for brain banking from obtaining, processing, and storage of brain material to bioethical and legal aspects should increase the scarce sapling of brain banking. "
Fever of unknown origin (FUO) is a diagnosis that describes a prolonged febrile illness without an established cause, despite investigations. From the first definition of the medical condition (given by Petersdorf and Beeson in 1961) the diagnostic criteria have changed over time, intending to improve the management and outcome of these patients. The main causes of FUO fall into 4 categories: infectious, non-infectious (inflammatory), neoplastic and diverse causes. The etiology of FUO has changed over time, due to ever-changing disease patterns and the development of diagnostic techniques. A significant percentage of patients with FUO remain without an etiologic diagnosis, despite advanced diagnostic tests. Gathering potentially diagnostic clues through history, physical examination and nonspecific key paraclinical abnormalities is the basis for the diagnosis of FUO.
"Introduction: As general population tends to have increasing life expectancy, the risk associated with developing chronic kidney disease (CKD) with multiple incapacitating concequences, also increases. Method: For the present study, we registered the data from the observation files of 37 patients diagnosed with CKD undergoing treatment by chronic hemodialysis and noted the CKD associated diagnoses included in the notion of comorbidities. We monitored their statistical incidence both in the whole group and separately, in women and men using TTEST and CORREL. Results: The median age of the subjects was 55.86 (± 12.00) years. The study population mean weight was 74.90 (± 14.44) kg, with a mean weight of 69.33 kg for female subjects, and 77.92 kg for males, respectively. Diabetes was identified in 35.13% of patients, whilst heart failure was present in 16.21% of patients. Conclusions: Following the analysis of the information about the patients with CKD in the dialysis program, which we included in the study group, we observed the existence of variations that occur with age, significant correlations between age and weight and between albuminemia and weight. The most common comorbidity is high blood pressure followed by anemia. "
Gut microbiota is a superorganism involved in homeostasis and in pathogenesis. Microbiota composition is influenced by several factors such as: type of birth (cesarean or natural), role of age, role of diet. Pathological consequences of certain type of diet (especially western type of diet) may, in fact, be mediated by gut microbiota alteration. Also few studies have investigated the issue of gut microbiota composition in patients suffering of colorectal cancer, several reports notice relevant differences. Certain pathogenic bacteria in gut microbiota have been extensively studied in relation to their role in colorectal cancer. Thus, Fusobacterium nucleatum, which is abundant in colorectal cancer patient's colon, may initiate the progression from adenoma to adenocarcinoma. A suggested pattern of oncogenesis in colorectal cancer may be represented by this: dysbiosis-inflammation-oncogenesis. A metanalysis that has been published in 2006 concluded a protective role of probiotics in colorectal cancer and in colonic adenoma.
Diabetes mellitus is a serious condition, causing multiple health problems due to the disease itself, but also to the complications that these patients are predisposed to. Being a current health problem, many patients tend to disregard the doctor's recommendations concerning the necessary measures to maintain adequate and continuous control of the glycaemia levels. This, in turn, may cause complications, which include neuropathy, microangiopathy and a predisposition to infections due to weak local defence mechanisms. In otorhinolaryngology, the infectious pathology is one of the most often causes for presentation to the physician. Ranging from common otitis, acute pharyngitis or laryngitis and sinusitis, these different entities will cause significant discomfort for the patient, prompting the need for medical care. In patients with diabetes, the natural course of the disease is altered, with more severe symptoms, a more extended period of recovery and the predisposition for aggravated cases with the tendency to complications. Such complications may be life-threatening if we take into account the complications associated with acute sinusitis for example, which include orbital or cerebral abscesses. Our paper aims to present the authors experience on the complete approach of patients with infectious pathology concerning the sinuses associating diabetes mellitus. Always, we must keep in mind that patients with diabetes represent a particular class of patients that require a personalized approach. They are predisposed to a vicious circle, in which the infection causes diabetes imbalance, which in turn decreases the defense mechanism and predisposes to complications. The correct management must always include a proper control of diabetes, a complete evaluation that will determine if complications are already present and aggressive management of the infection, with regular check-ups to determine the evolution of the patient.
