Is PHEEM a multi-dimensional instrument? An international perspective

Aim: To look at the characteristics of Postgraduate Hospital Educational Environment Measure (PHEEM) using data from the UK, Brazil, Chile and the Netherlands, and to examine the reliability and characteristics of PHEEM, especially how the three PHEEM subscales fitted with factors derived statistically from the data sets. Methods: Statistical analysis of PHEEM scores from 1563 sets of data, using reliability analysis, exploratory factor analysis and correlations of factors derived with the three defined PHEEM subscales. Results: PHEEM was very reliable with an overall Cronbach`s alpha of 0.928. Three factors were derived by exploratory factor analysis. Factor One correlated most strongly with the teaching subscale (R=0.802), Factor Two correlated most strongly with the role autonomy subscale (R=0.623) and Factor Three correlated most strongly with the social support subscale (R=0.538). Conclusions: PHEEM is a multi-dimensional instrument. Overall, it is very reliable. There is a good fit of the three defined subscales, derived by qualitative methods, with the three principal factors derived from the data by exploratory factor analysis.

Fascicular Topography of the Suprascapular Nerve in the C5 Root and Upper Trunk of the Brachial Plexus: A Microanatomic Study From a Nerve Surgeon`s Perspective

BACKGROUND: In patients with supraclavicular injuries of the brachial plexus, the suprascapular nerve (SSN) is frequently reconstructed with a sural nerve graft coapted to C5. As the C5 cross-sectional diameter exceeds the graft diameter, inadequate positioning of the graft is possible. OBJECTIVE: To identify a specific area within the C5 proximal stump that contains the SSN axons and to determine how this area could be localized by the nerve surgeon, we conducted a microanatomic study of the intraplexal topography of the SSN. METHODS: The right-sided C5 and C6 roots, the upper trunk with its divisions, and the SSN of 20 adult nonfixed cadavers were removed and fixed. The position and area occupied by the SSN fibers inside C5 were assessed and registered under magnification. RESULTS: The SSN was monofascicular in all specimens and derived its fibers mainly from C5. Small contributions from C6 were found in 12 specimens (60%). The mean transverse area of C5 occupied by SSN fibers was 28.23%. In 16 specimens (80%), the SSN fibers were localized in the ventral (mainly the rostroventral) quadrants of C5, a cross-sectional area between 9 o`clock and 3 o`clock from the surgeon`s intraoperative perspective. CONCLUSION: In reconstruction of the SSN with a sural nerve graft, coaptation should be performed in the rostroventral quadrant of C5 cross-sectional area (between 9 and 12 o`clock from the nerve surgeon`s point of view in a right-sided brachial plexus exploration). This will minimize axonal misrouting and may improve outcome.

Hypomania: a transcultural perspective

This study examined the transcultural robustness of a screening instrument for hypomania, the Hypomania Checklist-32. first revised version(HCL-32 R1) It was carried out in 2606 patients from twelve countries in five geographic regions (Northern, Southern and Eastern Europe, South America and East Asia) In addition, GAMIAN Europe contributed data from its members Exploratory and confirmatory factor analyses were used to examine the transregional stability of the measurement properties of the HCL-32 R 1, including the influence of sex and age as covariates A cross cultures, a two-factor structure was confirmed the first factor (F 1) reflected the more positive aspects of hypomania (being more active, elated, self-confident, and cognitively, enhanced), the second factor (F2) reflected the more negative aspects (being irritable, impulsive, careless. more substance use). The measurement properties of the HCL-32 R1 were largely invariant across cultures Only few items showed transcultural differences in their relation to hypomania as measured by the test F2 was higher among men and in more severe manic syndromes, F1 was highest in North and East Europe and lowest in South America Vie scores decreased slightly with age The frequency of the 32 items showed remarkable similarities across geographic areas, with two exceptions. South Europeans had lower symptom frequencies in general and East Europeans higher rates of substance use These findings support the international applicability of the HCL-32 R1 as a screening instrument for hypomania

Mothers of children with cerebral palsy with or without epilepsy: a quality of life perspective

Methods. aEuro integral Thirty mothers of disabled children participated in the study. The control group comprised of 18 healthy mothers of children without disabilities. All mothers agreed to participate in the study. They completed the evaluation forms of the SF-36 health survey, a well-documented, self-administered QOL scoring system. Results. aEuro integral The results of our study support the premise that mothers of children with CP, as a group, have poorer QOL than mothers of not disabled children. Conclusions. aEuro integral We also observed that mothers of children with CP and epilepsy have poorer QOL than mothers of children with CP without epilepsy.
