Clinicopathological analysis of odontogenic tumors over 22 years period: Experience of a single center in northeastern Brazil
2018
Background Odontogenic tumors (OTs) are uncommon neoplastic lesions of the maxilla and mandible, which present difficult diagnosis and therapeutics. This paper aims to determine the frequency and distribution of OTs, over a period of 22 years, at a public university in Northeastern Brazil. Material and Methods We reviewed all cases of OTs from oral pathology laboratory of Federal University of Rio Grande do Norte (UFRN), from 1996 to 2017. The tumors were classified according to the latest (2017) World Health Organization Classification of Tumors. Data on age, gender, anatomic site, symptomatology, radiographic findings and tumor size were analyzed. Results In the analyzed period, 247 cases…
Time and feasibility of prevention in primary care
2016
BACKGROUND Prevention is an essential task in primary care. According to primary care physicians (PCPs),lack of time is one of the principal obstacles to its performance. OBJECTIVE To assess the feasibility of prevention in terms of time by estimating the time necessary to perform all of the preventive care recommended, separately from the PCPs and patient's perspectives, and to compare them to the amount of time available. METHODS A review of the literature identified the prevention procedures recommended in France, the duration of each procedure and its recommended frequency, as well as PCPs' consultation time. A hypothetical patient panel size of 1000 patients, representative of the Fren…
Depression and functional impairment independently contribute to decreased quality of life in cancer patients prior to chemotherapy
2007
An inverse association either between depression or impaired functional status and quality of life (QoL) has been reported for cancer patients, but the independent effect of depression or depressive symptoms and of functional impairment on QoL is unclear.We investigated the prevalence of depression or depressive symptoms with the Beck Depression Inventory (BDI), the functional impairment with the ECOG-Performance-Status (ECOG-PS) and the QoL with the EORTC-QLQ-C30 questionnaire in a sample of 175 hospitalised cancer patients prior to the start of chemotherapy.Sixteen of 175 patients (9.1%) screened positive for major depression, 29 (16.6%) had mild to moderate depressive symptoms. In 11 of …
Two-Year Stability of Psychosis Proneness Scales and Their Relations to Personality Disorder Traits
2000
Two-year stability of Physical Anhedonia (PhA), Perceptual Aberration (PER), and Magical Ideation (MI) scale scores and their relation to personality disorder traits were examined. Additionally, the effects of a time-lagged (prospective) versus concurrent measurement of psychosis proneness and personality disorder traits were studied to examine the specificity of MI, PER, and PhA. With a non-college-student sample (n = 404), stability for PhA was sufficiently high, but for PER and MI, stability was moderate to low. The correlations between personality disorder traits and psychosis proneness scales demonstrate that simultaneous assessment leads to a more nonspecific pattern of associations f…
Location of Gliomas in Relation to Mobile Telephone Use: A Case-Case and Case-Specular Analysis
2011
The energy absorbed from the radio-frequency fields of mobile telephones depends strongly on distance from the source. The authors' objective in this study was to evaluate whether gliomas occur preferentially in the areas of the brain having the highest radio-frequency exposure. The authors used 2 approaches: In a case-case analysis, tumor locations were compared with varying exposure levels; in a case-specular analysis, a hypothetical reference location was assigned for each glioma, and the distances from the actual and specular locations to the handset were compared. The study included 888 gliomas from 7 European countries (2000-2004), with tumor midpoints defined on a 3-dimensional grid …
Progression of untreated mild thoracic Scheuermann's kyphosis – Radiographic and functional assessment after mean follow-up of 46 years
2017
There is no data available on the radiographic development of the Scheuermann's deformity. Our purpose was to investigate radiographic deformity progression and the relation between kyphosis progression and clinical outcome in patients with untreated Scheuermann's kyphosis.Thoracic kyphosis (Th4-Th12) was measured from standing lateral radiographs in 19 patients at baseline and after mean 46-year follow-up. Mean age at baseline was 19.2 and at follow-up 64.7 years. At follow-up, height, weight, hand grip strength, and hamstring tightness were measured, and sit-to-stand and walking tests were performed. Additionally general health and quality of life questionnaires were administered.The mean…
The epidemiology, treatment, and complication of ameloblastoma in East-Indonesia
2018
Background Ameloblastoma is a neoplasm classified as a benign epithelial odontogenic tumor of the jaws, grow slowly and are locally invasive. The aim of the present study was to investigate the incidence, treatment, and complication of patients with ameloblastoma in East-Indonesia during six years retrospective study. Material and Methods This retrospective study included 84 patients who were diagnosed with ameloblastoma from 2011 to 2016. There were 56 patients with treatment data available. Data from each patient, including gender, age, histologic type, the size of the tumor, radiologic form, tumor location, type of treatment, and complication were reviewed and analyzed retrospectively. R…
Randomized response estimates for the 12-month prevalence of cognitive-enhancing drug use in university students.
2013
STUDY OBJECTIVE: To estimate the 12-month prevalence of cognitive-enhancing drug use. DESIGN: Paper-and-pencil questionnaire that used the randomized response technique. SETTING: University in Mainz, Germany. PARTICIPANTS: A total of 2569 university students who completed the questionnaire. MEASUREMENTS AND MAIN RESULTS: An anonymous, specialized questionnaire that used the randomized response technique was distributed to students at the beginning of classes and was collected afterward. From the responses, we calculated the prevalence of students taking drugs only to improve their cognitive performance and not to treat underlying mental disorders such as attention-deficit-hyperactivity diso…
Long-Term Results of Internal Urethrotomy
1996
AbstractPurpose: A retrospective analysis was done of long-term results of internal urethrotomy to evaluate risk factors of stricture recurrence.Materials and Methods: Followup studies were performed of 937 patients with urethral strictures treated with internal urethrotomy. Of the patients 357 were treated at Mainz University between 1977 and 1989 (mean followup 4.6 years) and 580 were treated at Bonn University between 1974 and 1986 (mean followup 3.2 years).Results: Strictures recurred in 96 of 357 (26.9 percent) and 260 of 580 (44.8 percent) patients, respectively. Risk factors for recurrence were etiology (post-transurethral resection and inflammation), stricture longer than 1 cm. and …
Long-term followup of buccal mucosa onlay graft for hypospadias repair: analysis of complications.
2004
We review the long-term results of buccal mucosa onlay grafting for urethral reconstruction in hypospadias surgery in patients with followup of at least 5 years.We retrospectively evaluated 132 patients who underwent buccal mucosa onlay graft for hypospadias repair, including 34 who underwent "salvage" grafting, during a 10-year period at our institution. In 49 cases with available followup longer than 5 years (average 6.2) complications were analyzed in detail.The overall complication rate was 24% (12 of 49 patients), with all but 3 complications occurring during the first postoperative year (3 fistulas, 1 stricture, 1 meatal stenosis, 2 graft contractures, 2 scars at oral harvesting site)…
