L’actualité des rickettsioses

Rickettsiae are strictly intracellular bacteria belonging to the Rickettsiaceae family. They are transmitted by various arthropods species, which are either vectors or reservoirs for the bacteria. The specific association between Rickettsieae and the vector are extensively studied, moreover Rickettsieae associated diseases are part of a continuously evolving field. Nevertheless, some rickettsiosis, such as epidemic typhus, have been described since the 16th century. Emerging diseases related to these bacteria are being investigated as well as new species, the implication of which is not always clear in human pathology when they are discovered. Some of these diseases are benign, others may be potentially fatal. Clinicians must therefore be aware of them. These issues are reviewed.

Patterns of sexual abuse and assault

Patterns of sexual abuse and sexual assault are analyzed from 162 reports involving victims with disabilities. Results suggest that abuse and assault are frequently repeated and chronic, often result in significant harm to the victim, and are rarely reported to child welfare or law enforcement authorities. Many offenses are committed by paid service providers and occur in disability service settings, but other offenses occur in the same situations as sexual abuse and assault of victims without disabilities. Victims are predominantly female and offenders are predominantly male. Charges and convictions are rare. Victims with disabilities often experience difficulty obtaining treatment services that are accessible and appropriate to their needs. Discussion considers a multifactorial, ecological model of abuse and recommends some possible prevention strategies.     

Host range and emerging and reemerging pathogens

An updated literature survey identified 1,407 recognized species of human pathogen, 58% of which are zoonotic. Of the total, 177 are regarded as emerging or reemerging. Zoonotic pathogens are twice as likely to be in this category as are nonzoonotic pathogens. Emerging and reemerging pathogens are not strongly associated with particular types of nonhuman hosts, but they are most likely to have the broadest host ranges. Emerging and reemerging zoonoses are associated with a wide range of drivers, but changes in land use and agriculture and demographic and societal changes are most commonly cited. However, although zoonotic pathogens do represent the most likely source of emerging and reemerging infectious disease, only a small minority have proved capable of causing major epidemics in the human population.

Alternative methods for testing treatment effects on the basis of multiple outcomes: simulation and case study

In clinical trials multiple outcomes are often used to assess treatment interventions. This paper presents an evaluation of likelihood-based methods for jointly testing treatment effects in clinical trials with multiple continuous outcomes. Specifically, we compare the power of joint tests of treatment effects obtained from joint models for the multiple outcomes with univariate tests based on modeling the outcomes separately. We also consider the power and bias of tests when data are missing, a common feature of many trials, especially in psychiatry. Our results suggest that joint tests capitalize on the correlation of multiple outcomes and are more powerful than standard univariate methods, especially when outcomes are missing completely at random. When outcomes are missing at random, test procedures based on correctly specified joint models are unbiased, while standard univariate procedures are not. Results of a simulation study are reported, and the methods are illustrated in an example from the Clinical Antipsychotic Trials of Intervention Effectiveness for schizophrenia.

The Domestication of Health Care: Health Advice to Canadian Mothers 1993–2008 in Today's Parent

The purpose of this article was to describe and analyze the ways that parents' and children's health are portrayed in health advice to parents in Canada's major mass print media magazine entitled Today's Parent, from 1993 to 2008. The qualitative content analysis noted three significant themes, including: most health issues are easily managed by mothers using common sense at home; mothers are responsible, healthy, energetic, and capable managers and experts who are able to work and advocate for their children's health; and mothers are able to critically assess doctors and medical care. Finally, anomalous stories are highlighted and some of the underlying assumptions of the stories are discussed. The substantive and practical consequences of these findings regarding parental health beliefs and actions are discussed.     

Maltreatment and Behavioral Characteristics of Youth Who Are Deaf and Hard-of-Hearing

This paper summarizes the available literature on child abuse and neglect among children with disabilities in general and considers children who are deaf and hard-of-hearing within this larger rubric given the low prevalence rates of children who are deaf and hard-of-hearing among the disabled population. This procedure allows for comparisons between disabilities as well as abused and non-abused children who are deaf and hard-of-hearing. Maltreatment data on children who are deaf and hard-of-hearing in a large epidemiological study of the prevalence of child maltreatment among children with disabilities are summarized. Children who are deaf and hard-of-hearing comprised 6.1% of the disabled population who were identified as victims of maltreatment. Their most prevalent form of maltreatment was neglect, followed by physical abuse and sexual abuse. Although children who are deaf and hard-of-hearing are significantly more likely to be maltreated by immediate family members, placement in a residential school is a risk factor for sexual and physical abuse. Maltreated children who are deaf and hard-of-hearing exhibit significantly more behavior problems including Post Traumatic Stress Disorder related behaviors than nonmaltreated peers.
