Beta-catenin and surviving expression in keratocystic odontogenic tumor (KCOT). A comparative immunohistochemical study in primary, recurrent and nev…
2013
Aim: To determine the epithelial expression of ß-catenin and survivin in sporadic (primary, and recurrent) and nevoid basal cell carcinoma syndrome (NBCCS) keratocystic odontogenic tumour (KCOT) in order to assess activation of the ß-catenin pathway and evidence of apoptotic inhibition, processes that may contribute to the known differences in their biological behaviour. Materials and Methods: Sections from 40 cases of KCOT (19 sporadic/primary; 9 sporadic/recurrent and 12 NBCCS-associated) were immunohistochemically stained for ß-catenin and survivin. The extent and intensity of immunoreactivity within the lining epithelium was assessed, using semi-quantitative scales, independently by two…
Pulpal ischemia in man: effects on detection threshold, A-delta neural response and sharp dental pain
1999
— Preferential blocks of peripheral nerves have shown that myelinated nerves are more susceptible to local compression and less resistent to asphyxia than unmyelinated fibers. Since two groups of functionally different nociceptors exist in the dental pulp, it is of theoretical and clinical interest to determine the influence of ischemia on the sensitivity of human dental pulp, using standard means for testing tooth vitality and at the same time investigating the intensity coding in one pathway of the afferent trigeminal system. Adrenaline was used to study the differential effect of adrenaline-induced ischemia on intradental A-delta nerve activity (INA) and the concomitant sharp pain, as we…
Histological findings in direct inguinal hernia
2013
Abstract BACKGROUND: The study is focused on recognizing the histological changes of the structures close to and around the hernia opening in patients having direct inguinal hernia. METHODS: In 15 patients with primary bilateral direct inguinal hernia who underwent a Stoppa open posterior inguinal hernia repair, tissue specimens from the abdominal wall surrounding a direct hernia border were excised for histological examination. These findings in patients with direct inguinal hernia were compared with tissue specimens excised from the fossa inguinalis media of cadavers without hernia. RESULTS: Significant degenerative modifications such as fibrohyaline degeneration and fatty substitution of…
Influence of gender and social factors on oral health, treatment degree and choice of dental restorative materials in patients from a dental school.

Influence of gender and social factors on oral health, treatment degree and choice of dental restorative materials in patients from a dental school. Abstract: Objective: The attitude towards oral health is influenced by gender, the level of education and the social background of the patients The aim of the present study was to determine a possible relationship of gender, the educational level and the oral health as well as the choice of dental restorations. Methodology: A total of 2374 outpatients (age: 18–80 years) from a University dental school were assessed. …
Glut-1 Expression and In Situ CD1a/CD57 Immunologic Deficit in Keratoacanthoma and Squamous Cell Carcinoma of Immunocompetent Patients
2011
It is not easy to reach a differential diagnosis between keratoacanthoma (KA) and squamous cell carcinoma (SCC) and furthermore there is still considerable discussion about the relationship of these 2 tumors with immunity. To facilitate such a diagnosis, we assessed the Glut-1 antibody, reported to be strongly and diffusely expressed in SCC but never assessed in KA. We studied 43 lesions of immunocompetent patients: 17 SCCs, 13 typical KAs (tKAs), and 13 atypical KAs (aKAs), with histologic features of SCC in less than 30% of the lesions. In tKA, Glut-1 stained only the basal layers of the squamous nests (basal pattern) whereas in SCC the squamous nests were randomly and diffusely stained (…
Ketorolac, diclofenac, and ketoprofen are equally safe for pain relief after major surgery
2002
Background Ketorolac is approved for the relief of postoperative pain but concerns have been raised over a possible risk of serious adverse effects and death. Two regulatory reviews in Europe on the safety of ketorolac found the data were inconclusive and lacked comparison with other non-steroidal anti-inflammatory drugs. The aim of this study was to compare the risk of serious adverse effects with ketorolac vs diclofenac or ketoprofen in adult patients after elective major surgery. Methods This prospective, randomized multicentre trial evaluated the risks of death, increased surgical site bleeding, gastrointestinal bleeding, acute renal failure, and allergic reactions, with ketorolac vs di…
Human chromophobe cell renal carcinoma
1985
Twelve renal cell carcinomas composed of "chromophobe" cells are described. This is the first report of renal chromophobe cell tumors in humans neoplasms of this cell type having been described previously only in experimentally induced adenomas in animals. By light microscopy chromophobe cells have slightly opaque or finely reticular cytoplasm when stained with haematoxylin and eosin. They may be distinguished from the clear cells of hypernephroid renal cell carcinomas by the strongly positive reaction of their cytoplasm with Hale's (1946) colloidal iron method and the weaker positive reaction with alcian blue. Vesicular structures, often containing internal vesicles, and possibly derived f…

Investigation of the maxillary lateral incisor agenesis and associated dental anomalies in an orthodontic patient population
2011
CEYLAN, Ismail/0000-0002-8693-4175; KAMAK, HASAN/0000-0003-1910-3694 WOS: 000314401800025 PubMed: 22549676 Objectives: The aim of this study was to investigate the prevalence of maxillary lateral incisor (MLI) agenesis and associated dental anomalies as well as skeletal patterns in an orthodontic population, and then to compare it with the prevalence of these anomalies in the general population. Study Design: The material of the present study included the records of the 3872 orthodontic patients. The followings were recorded for each subject with the agenesis of MLI: Age, sex, unilateral or bilateral absence, anterior-posterior skeletal relationship of the maxilla and mandible, and presence…
Accidental dental displacement into the maxillary sinus during extraction maneuvers: a case series
2020
Background The aims of this study were to describe the clinical findings of patients that suffered teeth displacement into the maxillary sinus, and to report the surgical technique used to solve this complication. Material and Methods A retrospective observational study was conducted involving patients that suffered a displacement of teeth into the maxillary sinus. Demographic and clinical data were recorded from the affected patients and a descriptive statistical analysis was made of the study variables. Results A total of nine patients were enrolled, six males (66.7%) and three females (33.3%), with a mean age of 36.0 years (range 22-54). In five patients (55.5%) the displaced teeth remai…
