Association Between Clinical and Microbiologic Cluster Profiles and Peri-implantitis
2017
Purpose: The correlation between associated local factors and peri-implantitis remains unknown. The aim of this study was to investigate the association between the clinical and microbiologic profiles and periimplantitis to eventually categorize different groups of this disease. Materials and Methods: Subjects with at least one implant presenting signs of peri-implantitis were selected. The clinical, radiographic, occlusal, and microbiologic profiles of these infected implants were collected. Cases were classified into five peri-implantitis groups according to potential disease-triggering factors: surgically, prosthetically, biomechanically, purely plaque-associated, and a combination of th…
Sibship size, birth order and psychotic experiences: Evidence from 43 low- and middle-income countries.
2018
Background: Sibship size and birth order may be contributing factors to the multifactorial etiology of psychosis. Specifically, several studies have shown that sibship size and birth order are associated with schizophrenia. However, there are no studies on their association with psychotic experiences (PE). Methods: Cross-sectional, community-based data from 43 low- and middle-income countries which participated in the World Health Survey were analyzed. The Composite International Diagnostic Interview was used to identify four types of past 12-month PE. The association of sibship size and birth order with PE was assessed with multivariable logistic regression. Results: The final sample consi…
Occupation and small bowel adenocarcinoma: a European case-control study
2000
OBJECTIVES—Because of the rarity of small bowel adenocarcinoma (SBA), little is known about the aetiology of this disease. This study aimed to identify occupational clustering of cases SBA as a systematic approach to new hypotheses on the aetiology of this disease. METHODS—A European multicentre case-control study was conducted in 1995-7, inclusive. Incident cases aged 35-69 years with SBA (n=168) were recruited before acceptance by a pathologist. Altogether 107 cases and 3915 controls were accepted, of which 79 cases, 579 colon cancer controls, and 2070 population controls were interviewed. RESULTS—The strongest industrial risk factors for SBA taking account of 10 years' exposure lag were …

Clinical Perspective on Antihypertensive Drug Treatment in Adults With Grade 1 Hypertension and Low-to-Moderate Cardiovascular Risk:An International …
2017
Hypertension is a leading risk factor for disease burden globally. An unresolved question is whether grade 1 hypertension (140-159/90-99. mm. Hg) with low (cardiovascular mortality <1% at 10 years) to moderate (cardiovascular mortality ≥1% and <5% at 10 years) absolute total cardiovascular risk (CVR) should be treated with antihypertensive agents. A virtual international consultation process was undertaken to summarize the opinions of select experts. After holistic analysis of all epidemiological, clinical, psychosocial, and public health elements, this consultation process reached the following consensus in hypertensive adults aged <80 years: (1) The question of whether drug treat…
Different prevalence of some indices of cardiac and vascular impairment in normal weight and obese patients with essential arterial hypertension
1989
Certain physiopathological features that differentiate essential arterial hypertension in normal weight and obese patients are recalled. The results of a retrospective study carried out in 293 hypertensive patients admitted to the Clinic in recent years are reported with a view to evaluating the prevalence of certain parameters (ischaemic cardiopathy, left ventricular hypertrophy, renal, vasculo-cerebral and retinal impairment) in patients subdivided into two groups: normal weight and obese. The study showed in the first group a higher prevalence of signs of ischaemic cardiopathy; in the second a higher prevalence of left ventricular hypertrophy. This difference is accentuated in the subgro…
Cognitive and social impairments in patients with superficial siderosis
2005
Superficial siderosis of the CNS is a rare condition, caused by deposition of haemosiderin in the superficial layers of the CNS due to repeated chronic subarachnoid or intraventricular haemorrhage. Typically, the hindbrain structures, especially the cerebellum, are most affected. There is a surprising lack of studies investigating in detail the behavioural functioning of patients with such a condition. In this study, we document for the first time the cognitive, social and emotional processing of six patients with a confirmed clinical diagnosis of superficial siderosis. They were aged between 40 and 62 years, with a mean age of 50.2 years; four were male. We administered a comprehensive bat…
Etiology of Homosexuality and Attitudes Toward Same-Sex Parenting: A Randomized Study
2013
Attribution theory suggests the hypothesis that heterosexuals' attitudes toward homosexual sexual orientation will be more negative when homosexuality is attributed to controllable causes. Our randomized study analyzed (a) whether beliefs about the genetic or environmental etiology of the homosexual sexual orientation can be immediately modified by reading a text and (b) the causal effect of attributions about the controllability (environmental etiology) or noncontrollability (genetic etiology) of homosexual sexual orientation on the rejection of same-sex parenting and their social rights. The sample was composed of 190 Spanish university students with a mean age of 22.07 years (SD = 8.46).…
Pseudoachalasia: a case series and analysis of the literature.
2005
Pseudoachalasia frequently cannot be distinguished from idiopathic achalasia by manometry, radiologic examination or endoscopy. Mechanisms proposed to explain the clinical features of pseudoachalasia include a circumferential mechanical obstruction of the distal esophagus or a malignant infiltration of inhibitory neurons within the myenteric plexus.Between January 1980 and December 2002, the clinical features of 5 patients with pseudoachalasia and 174 patients with primary achalasia, diagnosed in a single center, were compared. A literature analysis of the etiology of pseudoachalasia for the time period 1968 to December 2002 was performed. The search concentrated on the databases and online…
Prevalence of acne vulgaris and its clinico-epidemiological pattern in adult patients: Results of a prospective, observational study.
2021
Background Acne is a common disorder in adolescents. The prevalence of acne in adults is also increasing. There are only a few Indian studies on the prevalence and clinical features of adult acne. Aims To evaluate the prevalence and possible etiological and aggravating factors of acne in adult population. Methods Adult patients more than 25 years with acne were enrolled, and detailed history and examination were recorded. Type of acne, age, gender, area of involvement, and associated factors were noted. Results Out of 24,056 adult patients, 180 had acne, with the prevalence of 0.74%. Mean age of patients with acne was 30.1 years. A total of 81.7% patients with acne were female and 68.3% had…
