Restructuring a competency-based orientation for registered nurses.
A competency-based orientation is an orientation program that focuses on a new employee's ability to actually perform the expectations of his or her role in a particular setting. It differs from a traditional model in which the focus is on the cognitive knowledge necessary for the role. The authors will identify key elements educators may consider when evaluating such a program. The process used by the author's organization to evaluate and restructure the competency-based orientation program for registered nurses is also described.

Survival of diabetic hypertensive patients.
Seventy-nine of 673 patients attending a hypertensive outpatient clinic were classified as diabetics at the first examination. These patients were age- and sex-matched to two control groups: nondiabetic hypertensives and the background population. Nondiabetic hypertensive patients had a significantly poorer survival than expected during a 10-year observation period; the survival of diabetic hypertensives was even poorer, although not significantly. No sex difference was observed in the survival rates of hypertensive diabetics, neither was a difference seen between insulin-dependent and non-insulin-dependent patients. Acute myocardial infarction was the most frequent cause of death in both diabetic (40%) and nondiabetic (42%) hypertensive persons.

Peripheral vein infusion of dextrose/amino acid solutions +/- 20% fat emulsion.
The purpose of this study was to evaluate the incidence of phlebitis occurring during peripheral infusion of nutrient solutions with and without 20% fat emulsions. Eighty patients were randomly assigned to one of four groups: (1) dextrose/amino acids-630 mOsmol/liter; (2) dextrose/amino acids/fat emulsion-706 mOsmol/liter; (3) dextrose/amino acids-882 mOsmol/liter and; (4) dextrose/amino acids/fat emulsion-983 mOsmol/liter. The peripheral infusion site was examined daily and the number of changes in infusion sites were recorded and the degree of phlebitis encountered was graded. The four groups were similar in the mean number of iv site changes per patient and per day. The average grade of phlebitis was similar (0.23-0.27 events/day) among the four groups. Infiltration occurred more frequently with butterfly needle while phlebitis occurred more frequently with plastic angiocatheters. Patients appeared to tolerate peripheral infusion with high osmolar solutions just as well as lower osmolar solutions. Concurrent infusion with a 20% fat emulsion did not alter the number of iv site changes or the incidence or degree of phlebitis reported and thus, did not appear to have a protective effect on the vein when infused with dextrose/amino acid solutions.

Adductor tendinitis and musculus rectus abdominis tendopathy.
Groin injuries are becoming more common today in soccer. Conservative treatment consisting of rest, physiotherapy, and medication yields favorable results in only 38% of the long-standing lesions. Operative treatment is indicated in selected cases. Better knowledge of the underlying pathology and a more accurate initial conservative treatment directed to the ethiopathogenesis could solve many of the problems. However, in our experience a simple subcutaneous adductor tenotomy and/or a rectus abdominis tenotomy in combination with a fasciaplasty was done successfully in 75 of 81 patients. There was no loss of power in this group of patients as measured and compared with a control group.

Evolution, discovery, and interpretations of arthropod mushroom bodies.
Mushroom bodies are prominent neuropils found in annelids and in all arthropod groups except crustaceans. First explicitly identified in 1850, the mushroom bodies differ in size and complexity between taxa, as well as between different castes of a single species of social insect. These differences led some early biologists to suggest that the mushroom bodies endow an arthropod with intelligence or the ability to execute voluntary actions, as opposed to innate behaviors. Recent physiological studies and mutant analyses have led to divergent interpretations. One interpretation is that the mushroom bodies conditionally relay to higher protocerebral centers information about sensory stimuli and the context in which they occur. Another interpretation is that they play a central role in learning and memory. Anatomical studies suggest that arthropod mushroom bodies are predominately associated with olfactory pathways except in phylogenetically basal insects. The prominent olfactory input to the mushroom body calyces in more recent insect orders is an acquired character. An overview of the history of research on the mushroom bodies, as well as comparative and evolutionary considerations, provides a conceptual framework for discussing the roles of these neuropils.
