Although male partner cooperation is often essential for successful use of the female condom, only a few studies have directly assessed men's experiences of using the device. We examined barriers to and facilitators of female condom use via qualitative in-depth interviews with 38 young men (18 to 28 years) in South Africa whose partners, all university students, were enrolled in a female condom intervention trial. In all, 21 men used the female condom; the remaining 17 did not attempt use. The main facilitators to female condom use were convenience of use for men, curiosity to see how female condoms compared to male condoms, enhanced sexual sensation, and perceptions of better safety and comfort of the device compared to male condoms. The main barriers were men's limited familiarity with the device, insertion difficulties, and men's concerns about loss of control over sexual encounters. We recommend that human immunodeficiency virus (HIV) prevention and condom promotion ...

There are frequent applications for endoscopy in neurosurgery. However, endoscopic surgery in children has peculiar characteristics and is associated with different rates of success. In this study, the authors report on their experience with 134 consecutive endoscopy procedures performed in 126 patients<18 years of age. Between April 1993 and October 2007, 134 endoscopic procedures were performed in 126 children. Indications for surgery included brain tumors in 48 children, cystic lesions in 24, aqueductal stenosis in 23, various malformations in 20, hemorrhage and infarction in 6, and isolated ventricles in 5 children. In this long-term followup study, data were analyzed with respect to clinical and radiological success rates, as well as shunt dependence both in relation to lesion origin, and to the type of endoscopic procedure performed (endoscopic third ventriculostomy [ETV], septostomy, aqueductoplasty, or cystocisternostomy). Finally, the influence of patient age on the succ...

Previous experimental studies have highlighted that citrulline (CIT) could be a promising pharmaconutrient. However, its pharmacokinetic characteristics and tolerance to loading have not been studied to date. The objective was to characterise the plasma kinetics of CIT in a multiple-dosing study design and to assess the effect of CIT intake on the concentrations of other plasma amino acids (AA). The effects of CIT loading on anabolic hormones were also determined. Eight fasting healthy males underwent four separate oral loading tests (2, 5, 10 or 15 g CIT) in random order. Blood was drawn ten times over an 8 h period for measurement of plasma AA, insulin and growth hormone (Gh). Urine samples were collected before CIT administration and over the next 24 h. None of the subjects experienced side effects whatever the CIT dose. Concerning AA, only CIT, ornithine (ORN) and arginine (ARG) plasma concentrations were affected (maximum concentration 146 (sem 8) to 303 (sem 11) μmol/l (ARG) a...

Purpose A eutectic mixture of local anesthetics (EMLA) is commonly used to provide topical anesthesia for intravenous (iv) cannulation. One of its side effects is vasoconstriction, which may render cannulation more difficult. A gel formulation of amethocaine (Ametop™) is now commercially available. The aim of this study was to compare EMLA and Ametop™ with regard to the degree of topical anesthesia afforded, the incidence of vasoconstriction and the ease of iv cannulation. Methods Thirty two ASA 1 adult volunteers had a # 16 gauge iv cannula inserted on two separate occasions using EMLA and Ametop™ applied in a double blind fashion for topical anesthesia. Parameters that were recorded after each cannulation included visual analogue pain scores (VAPS), the presence of vasoconstriction and the ease of cannulation, graded as: 1 = easy, 2 = moderately difficult, 3 = difficult and 4 = failed. Results The mean VAPS ± SD after cannulation with Ametop™ M was 12 ± 9.9 and with EMLA was 25.3 ± 16.6 (P = 0.002). Vasoconstriction occurred after EMLA application on 17 occasions and twice after Ametop™ (P = 0.001). The grade of difficulty of cannulation was 1.44 ± 0.88 following EMLA and 1.06 ± 0.25 with Ametop™ (P = 0.023). Conclusions Intravenous cannulation was less painful following application of Ametop™ than EMLA. In addition, Ametop™ caused less vasoconstriction and facilitated easier cannulation. Its use as a topical anesthetic agent is recommended, especially when iv access may be problematic. Objectif Un mélange eutectique d’anesthésiques locaux (MEAL) est souvent utilisé pour l’anesthésie topique lors d’une canulation intraveineuse (iv). La vasoconstriction, qui est l’un des effets secondaires du MEAL, peut compliquer la mise en place d’une canule. Une présentation en gel d’améthocaïne (Ametop™) est maintenant offerte dans le commerce. Le but de la présente étude était de comparer le MEAL et l’Ametop™ en regard du degré d’anesthésie topique fourni, de l’incidence de la vasoconstriction et de la facilité de la canulation iv. Méthode: On a inséré, en deux occasions séparées chez 32 volontaires adultes d’état physique ASA 1, une canuleiv de calibre 16 en utilisant en double aveugle le MEAL et Ametop™ pour réaliser l’anesthésie topique. Après chaque canulation, on a enregistré les paramètres suivants: les scores de douleur à l’échelle visuelle analogue (EVA), la présence de vasoconstriction et la facilité de canulation notée 1 = facile, 2 = modérément difficile, 3 = difficile et 4 = impossible. Résultats Les scores moyens à l’EVA ± l’écart type ont été de 12 ± 9,9 à la suite de la canulation avec Ametop™ M et de 25,3 ± 16,6 après le MEAL (P = 0,002). La vasoconstriction est survenue en 17 occasions après l’application du MEAL et deux fois plus souvent après Ametop™ (P = 0,001). Le degré de difficulté de canulation a été de 1,44 ± 0,88 après le MEAL et de 1,06 ± 0,25 après Ametop™ (P = 0,023). Conclusion La canulation intraveineuse est moins douloureuse après l’application d’Ametop™ que celle du MEAL. De plus, l’Ametop™ a provoqué moins de vasoconstriction et a facilité l’introduction d’une canule. Son usage comme anesthésique topique est recommandé, surtout lorsqu’une action rapide est nécessaire ou que l’accèsiv peut être problématique.

More than 20 years ago Habib Davanloo coined the term unlocking of the unconscious to describe how the psychodynamic concept of the human unconscious can become accessible using the technique of Intensive Short-Term Dynamic Psychotherapy (ISTDP). According to Davanloo, the possibility that unconscious material will be revealed is greatly increased when therapeutic efforts promote dominance of the unconscious therapeutic alliance over unconscious resistance. When these ingredients are present there is a psychic shift that allows unacceptable painful feelings to come to the surface. Toward adding further empirical support for the concept, in this article we compare outcomes between patients who experienced one or more major unlocking of the unconscious (N = 57) to those who did not experience major unlocking (N = 32) during ISTDP treatment. Significant and widespread differences were seen between these two groups, those with major unlocking had greater symptom reduction, interpersonal...

Dermatologists are increasingly confronted with patients affected by body dysmorphic disorder (BDD). BDD is characterized by excessive preoccupation with one or more perceived defect(s) or flaw(s) in physical appearance which are not observable or appear slight to others. So far, there have been only few studies examining the prevalence of BDD in dermatological outpatients. In addition, the need for psychotherapeutic support in dermatological outpatients with body dysmorphic concerns has not yet been systematically examined. The objective of the present study was therefore to investigate the frequency of body dysmorphic concerns as well as social adaptation and the need for psychotherapeutic support in the aforementioned patient group. A total of 252 dermatological outpatients seen at a German university hospital were consecutively enrolled, and examined using the Dysmorphic Concerns Questionnaire, the Social Adaptation Self-Evaluation Scale, and the German version of the University...

This article presents an up-to-date review of the literature on hormone augmentation in the elderly to help primary care physicians better evaluate and utilize hormone replacement and optimization strategies to benefit their patients. The scientific literature suggests that hormone supplementation with estrogen, progesterone, testosterone, growth hormone, and thyroid hormone has the potential to improve quality of life and to prevent, or reverse, the many symptoms and conditions associated with aging, including fatigue, depression, weight gain,frailty, osteoporosis, loss of libido, and heart disease. Possible long-term side effects are also considered.

The author considers that whilst nurse tutors teach theory, nurse practitioners go on nursing in the same way that they always have done. There appears to be a chasm dividing theory and practice. This paper describes an attempt to leap that chasm. The paper identifies the problem, inherent in the nursing process that creates such difficulties in its implementation. The nursing process alone does not provide an adequate framework for nursing practice. The paper then describes how the translation of theory into practice took place on a ward in Brighton General Hospital, Brighton, England. The barrier between theory and practice is highlighted, along with a description of how the problems this presents to ward staff were overcome. The author considers that the attribution of cause is a key concept in the problem-solving approach, since it generates the question — Why?— and therefore that attribution of cause must be a concept in any model of nursing that is being used to implement the nursing process. The paper provides an example of how nursing models may be adapted, at ward level, to guide everyday practice, whilst retaining the conceptual framework ofthe model. The inference of the paper is that such a process could be applied to other models resulting in a greater use of theory in everyday nursing practice.

We investigated the occurrence and underlying processes of odor-color associations in French and American 6- to 10-year-old children (n = 386) and adults (n = 137). Nine odorants were chosen according to their familiarity to either cultural group. Participants matched each odor with a color, gave hedonic and familiarity judgments, and identified each odor. By 6 years of age, children displayed culture-specific odor-color associations, but age differences were noted in the type of associations. Children and adults in both cultural groups shared common associations and formed associations that were unique to their environment, underscoring the importance of exposure learning in odor-color associations.

Three interconnected positions are advocated: (1) although serving as a useful model, the immune self does not exist as such; (2) instead of a self/nonself demarcation, the immune system 'sees' itself, i.e., it does not ignore the 'self' or attack the 'other;' but exhibits a spectrum of responses, which when viewed from outside the system appear as discrimination of 'self' and 'nonself' based on certain criteria of reactivity. When immune reactions are conceived in terms of normal physiology and open exchange with the environment, where borders dividing host and foreign are elusive and changing, host defense is only part of the immune system's functions, which actually comprise two basic tasks: protection, i.e., to preserve host integrity, and maintenance of organismic identity. And thus (3) if the spectrum of immunity is enlarged, differentiating low reactive 'autoimmune' reactions from activated immune responses against the '...
