An Integrative Review of Literature Examining Psychometric Properties of Instruments Measuring Anxiety or Fear in Hospitalized Children

Anxiety and fear are among the most frequently reported emotional responses to hospitalization and are known to be contributing factors to pain and other negative patient outcomes. The first step in confronting unnecessary anxiety and fear is to identify valid and clinically feasible assessment instruments. The purpose of this paper is to review and evaluate instruments that measure children’s fear or anxiety associated with hospitalization or painful procedures. A search was conducted of published English-language literature from 1980 through 2010 with the use of Ovid Health and Psychosocial Instruments, Medline, Nursing/Academic Edition, Cinahl, and Google Scholar. Inclusion criteria specified that the self-report instrument: 1) was developed in English; 2) was developed for and/or widely used with hospitalized children or children undergoing medical procedures or treatment; and 3) had research evidence of psychometric properties from at least five different studies. A comprehensive review of the literature revealed only five fear or anxiety instruments with adequate testing for evaluation of reliability and validity. Although all instruments have beginning psychometric adequacy, no one tool stands out as superior to the others. Therefore, we recommend that researchers and clinicians exercise caution in choosing assessment instruments, balancing potential strengths with reported limitations. Using more than one tool (triangulating) may be one way to achieve more credible results. Knowledge of credible existing instruments alerts us to what is possible today and to the imperative for research that will improve communication with children tomorrow.     

Development of an acute obstructive hydrocephalus model in rats using N-butyl cyanoacrylate

Purpose  

Previous animal models of obstructive hydrocephalus that was frequently combined with subarachnoid inflammation are not suitable for investigating cerebrospinal fluid (CSF) flow between ventricles and cisterns in obstructive hydrocephalus. In this study, we attempted to develop a new animal model for obstructive hydrocephalus in rats sparing subarachnoid space using N-butyl cyanoacrylate (NBCA).     

Basal and residual lower esophageal pressures increase in old age in classic achalasia,but not vigorous achalasia

Background and Aim: The relationship between age and esophageal motility parameters (i.e. basal and residual pressure of the lower esophageal sphincter [LES]) remains to be established in achalasia patients, possibly because most previous studies did not distinguish between classic and vigorous achalasia patients. We investigated the relationship between age and esophageal motility parameters in both classic and vigorous achalasia patients. Methods: A retrospective review of esophageal manometry data in a single center was undertaken. Basal and residual pressure for LES was analyzed. A total of 103 achalasia patients were enrolled, comprising 84 classic and 19 vigorous types. They were subdivided into three different age groups as follows: 21–40 years old (group A), 41–60 years old (group B), and over 60 years old (group C). Results: In classic achalasia patients (M : F = 27:57, mean age = 44 ± 15 years old) the older age group showed a significantly higher basal LES pressure (49.62 ± 19.63 mmHg) than the younger age group (P < 0.0001). Moreover, the older age group also showed significantly high residual LES pressure (20.46 ± 8.61 mmHg) than the younger age group (P = 0.0006). In contrast, in vigorous achalasia patients (M : F = 12:7, mean age: 47 ± 15 years old) there were no difference between age and motility indices (all P > 0.05). Conclusion: In classic achalasia patients there appears to be a correlation between age and esophageal motility indices, especially basal and residual LES pressure. Such correlations do not appear to exist for vigorous achalasia patients.     

Nardostachys jatamansi extract protects against cytokine-induced β-cell damage and streptozotocin-induced diabetes

AIM: To investigate the anti-diabetogenic mechanism of Nardostachys jatamansi extract (NJE). METHODS: Mice were injected with streptozotocin viaa tail vein to induce diabetes. Rat insulinoma RINm5F cells and isolated rat islets were treated with interleukin1β and interferon-γ to induce cytotoxicity. RESULTS: Treatment of mice with streptozotocin resulted in hyperglycemia and hypoinsulinemia, which was conf irmed by immunohistochemical staining of the islets. The diabetogenic effects of streptozotocin were c...     

A Case of Primary Cutaneous Mucinous Carcinoma with Neuroendocrine Differentiation

Primary cutaneous mucinous carcinoma is a rare malignant tumor that originates from the deepest portion of the eccrine sweat duct. Common sites of involvement are the face and scalp. Biopsy shows dermal epithelial cell islands embedded in mucin pools separated by fibrous septae. It is difficult to differentiate this tumor histologically from metastatic adenocarcinoma. Recurrence after excision is common but metastases are rare. We report a primary cutaneous mucinous carcinoma with neuroendocrine differentiation on the right cheek of a 63-year-old man.
