Association Between Migraine and Headache Attributed to Stroke: A Case,Control Study

HEADACHE, Issue 10 2008
Katiuscia Nardi MD
Background., Several studies were carried out to investigate the occurrence of headache attributed to acute stroke in patients with a lifetime history of migraine. Methods., In a case,control series of 96 acute stroke patients with a lifetime history of migraine (M+) and 96 stroke patients without (M,), ischemic stroke patients only, without secondary infarction, were selected. The headache attributed to acute ischemic stroke was then analyzed. Results., (M+) patients complained of headache more often than (M,) patients (P < .0001), mainly in the 24 hours before stroke onset (P < .0001). Migraine-like features of headache were recognized in a greater proportion of cases in the (M+) patient group with ischemic stroke (P < .018). A preferential brainstem location of ischemic stroke in (M+) patients emerged compared with (M,) patients (P = .014). Discussion., The high prevalence of headache attributed to stroke in (M+) patients, in a relevant proportion of cases presenting as a sentinel headache, suggests that cerebral ischemia lowers the threshold for head pain more easily in these "susceptible" patients. The most frequent involvement of the brainstem in (M+) patients with ischemic infarction concurs with recent reports that emphasized a greater headache frequency when cerebral infarctions are localized in this structure or deep brain gray matter.

INFLUENCE OF ACID ADAPTATION ON THE SURVIVAL OF SALMONELLA ENTERITIDIS AND SALMONELLA TYPHIMURIUM IN SIMULATED GASTRIC FLUID AND IN RATTUS NORVEGICUS INTESTINE INFECTION

JOURNAL OF FOOD SAFETY, Issue 2 2010
KARLA JOSEANE PEREZ
ABSTRACT The aim of this study was to investigate the influence of acid adaptation in the survival of Salmonella Enteritidis (SE86) and Salmonella Typhimurium (ST99) during exposure to simulated gastric fluid (SGF) and in intestinal infection of Rattus norvegicus. Acid-adapted and nonadapted Salmonella strains were exposed to SGF (pH 1.5) and were inoculated by gavage in adult rats. Results indicated that acid-adapted SE86 survived significantly better (P < 0.05) than nonadapted SE86, nonadapted ST99 and acid-adapted ST99 in SGF. Nonadapted microorganisms were observed in higher counts in feces than acid-adapted strains, while acid-adapted microorganisms demonstrated higher counts in intestine samples, suggesting intestinal invasion capacity. Acid-adapted SE86 was recovered in higher counts from ileum-cecum junction than the other microorganisms. PRACTICAL APPLICATIONS Salmonella Enteritidis has been identified as the most frequent serovar involved with the foodborne outbreaks in Brazil. In Southern Brazil, a specific strain of Salmonella Enteritidis (SE86) has been involved with more than 90% of the salmonellosis occurring in the last years, and the main food vehicle is home-made mayonnaise frequently added with different quantities of vinegar, which can cause acid adaptation in Salmonella cells. The results of this work indicate that SE86 presented higher acid adaptation, which contributed to higher survival rates in simulated gastric fluid and better intestinal colonization. These results could be related to human virulence and the frequent involvement of this strain with foodborne outbreaks in southern Brazil. [source]

Examining developmental differences in the social-emotional problems among frequent bullies, victims, and bully/victims,

PSYCHOLOGY IN THE SCHOOLS, Issue 2 2009
Lindsey M. O'Brennan
Bullying poses a threat to children's social-emotional functioning and their perceptions of school climate, yet few studies have examined different types of social-emotional and behavior problems presented by children involved in bullying, as a bully, victim, or bully/victim across multiple school levels. The current study used data from 24,345 elementary-, middle-, and high-school students to examine the association between frequent involvement in bullying and aggressive impulsivity, attitudes toward aggressive retaliation, internalizing symptoms, peer relations, and perceptions of school climate. Logistic regression analyses indicated that bully/victims were most likely to display internalizing symptoms, problems in peer relationships, and have poorer perceptions of the school environment. Both frequent bullies and bully/victims displayed aggressive-impulsive behavior and endorsed retaliatory attitudes. High-school students frequently involved in bullying tended to display the greatest risk for internalizing problems, but less risk for aggressive impulsivity. Developmental trends and implications for prevention and early intervention are discussed. © 2008 Wiley Periodicals, Inc. [source]

Oral mucosal diseases: the inflammatory dermatoses

AUSTRALIAN DENTAL JOURNAL, Issue 2010
M Schifter
Abstract The oral inflammatory dermatoses is a term used to describe a number of predominantly immune-mediated disorders: lichen planus (LP), erythema multiforme (EM), the vesiculobullous diseases pemphigoid (MMP), pemphigus (PV) and epidermolysis bullosa acquisita (EBA). These conditions are characterized by frequent involvement of the oral mucosa and often associated with extraoral manifestations, particularly of the skin, but can involve the eyes, both the conjunctiva and sclera, the nasal and pharyngeal mucosa, as well as the genitals. Given their frequent, and sometimes initial involvement of the oral mucosa, oral health professionals need to be both familiar with the clinical features and presentations of these conditions, and appreciate their critical role in management. This paper reviews the clinical features and presentation of the oral dermatoses, provides guidance as to the appropriate investigations needed to differentiate and correctly diagnose these conditions, details the aetio-pathology of these diseases and discusses their management.

Values of urban Aboriginal parents: Food before thought

AUSTRALIAN OCCUPATIONAL THERAPY JOURNAL, Issue 1 2000
Alison Nelson
Using qualitative methodology, this study investigated values of urban Aboriginal parents, particularly with respect to parenting and child development. Data were collected from five urban-dwelling Aboriginal parents aged between 25 and 55 years. Participants were parents of children aged between 18 months and 25 years. All participants were also employed in the fields of education or health where they had frequent involvement with other indigenous parents through welfare support or school or health programs. Each informant participated in either an individual interview or focus group. Supplemental data were also collected from participant observation in a kindergarten setting. Descriptions of Aboriginal parents' values and parenting styles are reported. The main values included an emphasis on maintaining social relationships and cultural identity with an overriding need for survival and security. Implications for occupational therapy practice and further research with urban Aboriginal families are suggested. [source]
