Four distinct parenting styles have been described: authoritative, authoritarian, permissive, and uninvolved. Parenting styles have been associated with a myriad of child safety and health outcomes. However, the association between parenting style and child agricultural injury has not been explored. This study was conducted among farm parents in Wisconsin and Pennsylvania using a self-administered paper questionnaire. Parents responded to items inquiring about parenting styles, previous child agricultural injuries, personal demographics, and farm characteristics. A total of 238 farm parents responded to the survey. Over a third of respondents (34.3%) reported a child agricultural injury. About 41% of parents were classified as authoritative (demonstrating a high level of involvement and control), 35.7% as uninvolved, 13.3% as permissive, and 10% as authoritarian. In the univariable analyses of parenting style, notable elevations in child injury rates occurred for the authoritarian (RR = 1.96, 95% confidence interval (CI) 1.08 to 3.58, p = 0.0274) and uninvolved (RR = 1.58, 95% CI 1.00 to 2.50, p = 0.0506) categories as compared to the referent category of authoritative. In the multivariable analyses that were adjusted for confounding variables, the magnitude of the corresponding RR estimates were less dramatic, although a 69% elevation was still present for the authoritarian parenting style (RR = 1.69, 95% CI 0.91 to 3.15, p = 0.0975). The results of this study contribute to the growing body of literature suggesting that authoritative parenting is protective against risk-taking behaviors in childhood as well as reducing potential injury among children. Clinicians and safety experts should consider parenting styles when developing child agricultural injury prevention resources or interventions. [ABSTRACT FROM AUTHOR]

The records of 74 patients diagnosed as suffering from tuberculous (TB) bone or joint disease between 1969 and 1979 were analysed retrospectively. Most were resident in the Greater Manchester County. Thirty-eight patients were first-generation immigrants, and teenage males were particularly prominent in this group. In the indigenous patients the diagnosis was often delayed several months or years, and in a number of subjects there was a history of previous bone and joint tuberculosis. There was a wide range of affected sites, especially in the immigrant group, and evidence of nonarticular TB was found in only a minority of patients. Diagnosis is most satisfactorily based on open biopsy and submission of pathological material to culture and histology. British subjects were more likely to have to undergo remedial surgery for the disease, especially when weight bearing joints were involved. Antituberculous chemotherapy should be given for at least 1 year to prevent recurrence of the disease. [ABSTRACT FROM AUTHOR]

That disorders of cutaneous sensation are common in diabetes mellitus can be substantiated by quantitative cutaneous sensory testing. Cutaneous sensory disturbances are not clearly related to clinical factors such as the type, treatment, or duration of diabetes, or ocular complications. Diabetics can be distinguished from nondiabetics on quantitative examination of skin sensation. Juvenile diabetics appear to have fewer cutaneous abnormalities than adults who develop the disease, but the juvenile diabetic is not spared. Disorders of cutaneous sensation may represent a fundamental abnormality of the nervous system in diabetes mellitus. While altered peripheral sensory mechanisms are likely, abnormality of central sensory processing is not excluded by the results of this study. [ABSTRACT FROM AUTHOR]

Individuals with a severe mental illness and substance use disorder tend to have medical and social problems and to make slower progress in treatment than those who have either disorder alone. Nevertheless, little attention has been paid to the discovery of effective methods of modifying substance use in the severely mentally ill (SMI). The purpose of this study was to collect qualitative data as a way to help identify techniques that might help to change patterns of substance use in the SMI. The participants were 21 men and women who were psychiatric clinic outpatients and who had a current schizophrenia spectrum diagnosis. A total of 18 participants had a lifetime diagnosis of alcohol abuse or dependence, and 21 lifetime other drug diagnoses were recorded for the sample. These individuals participated in focus group discussions about topics related to substance use and people's experiences with trying to quit. The results showed that participants identified several therapeutic and extratherapeutic factors that helped them to initiate and maintain changes in their substance use, as well as factors that hindered change. The findings are related to knowledge about the effectiveness of substance use disorder treatment techniques in general, and implications of the data are discussed for the conduct of integrated treatment of individuals with severe mental illness and a substance use disorder.

State-of-the-science treatment of substance abuse relies on decisional balance activities (weighing pros and cons of continued substance use) to enhance motivation for change. Few data are available regarding the feasibility of these activities among persons dually diagnosed with schizophrenia and substance use disorder. To address this lacuna in the literature, we completed focus groups with 21 participants, all of whom had a schizophrenia-spectrum diagnosis and lifetime substance abuse or dependence. These key informants discussed the pros and cons of substance use as well as the pros and cons of quitting in response to a structured group interview. Our qualitative data indicate that persons living with schizophrenia can generate rich and diverse decisional balance information. We describe salient themes, contrast complementary perspectives (i.e., the pros of using and cons of quitting), and suggest treatment implications based on these findings.

Nineteen adolescents (average age 15 years, 3 months) were tested and retested using a standard 40 target, auditory oddball ERP paradigm across an interval of 1 year, 10 months to determine reliability of the ERP components, both in terms of intersubject stability and score agreement and in terms of trait (between-session reliability) versus state (within-session reliability). Significant trait stability was found for the N100, P200, and P300 latencies (r = .48, .51, and .74, respectively), and for P300 amplitude (r = .62), supporting the P300 as a reliable measure, with the stability required for group research but not necessarily for clinical applications. Discussion and examples illustrate the application of reliability information to the planning and evaluation of ERP paradigms.

To determine the site(s) responsible for the central cardiovascular effect of hypertonic saline, 0.2 ml of 1.5 M NaCl was administered to anesthetized dogs via three routes, a lateral ventricle, the third ventricle and the cisterna magna. Intracisternal administration of hypertonic NaCl produced much prompter pressor and tachycardic responses than did administration via the other two routes. Covering the ventral third ventricle region with a petroleum jelly plug had the effect of abolishing the pressor response to lateral ventricular hypertonic NaCl but did not modify the response to intracisternal hypertonic NaCl. By contrast, electrolytic lesion of the area postrema attenuated the rise in blood pressure produced by the intracisternal NaCl without affecting the response to lateral ventricular NaCl. These results indicate that at least two sites, the ventral third ventricle region in the hypothalamus and the area postrema in the lower brainstem, are responsible for the acute hypertension induced by an increase in NaCl concentration in the cerebrospinal fluid of the dog.

Our group showed previously that the heptapeptide angiotensin (1-7) [Ang-(1-7)] is a bioactive product of the renin-angiotensin system, and produces dose-dependent cardiovascular effects similar to those evoked by Ang II when microinjected into the nucleus tractus solitarii (nTS) of the rat. The effects of Ang II were compared with those of Ang-(1-7) on single neuron activity recorded from the medial nTS or dorsal motor nucleus of the vagus (dmnX) in perifused horizontal slices of the canine dorsomedial medulla. Ang II excited 48% of 31 medial nTS neurons, but only activated 14% of 22 dmnX cells. Ang-(1-7) also excited half of the medial nTS cells and 14% of the dmnXl neurons. Although most medial nTS neurons excited by Ang II were also activated by Ang-(1-7), two cells were excited by Ang II but not by Ang-(1-7), and one cell was excited by Ang-(1-7) but not by Ang II. Because Ang-(1-7) lacks direct vasoconstrictor effects, neurons in the dorsomedial medulla may have different receptor characteristics than peripheral tissues. The observation of a few medial nTS neurons excited by only one Ang peptide suggests that there may be a separate Ang-(1-7) receptor that participates in the physiological effects of Ang peptides mediated by the brain.
