Organisational justice and employee perceptions on hospital management.

PURPOSE: The purpose to clarify what kind of managerial challenges employees experience regarding organisational justice in hospitals. DESIGN/METHODOLOGY/APPROACH: This exploratory study of 8,971 employees working in 14 hospitals and examines the concept of organisational justice in management with qualitative and quantitative methods. FINDINGS: An inductive content analysis of the comments revealed five integrative frames describing challenges in hospital management at respondents' workplaces. These frames should be regarded as major managerial challenges in hospitals. These findings illustrate important antecedents of organisational justice and suggest that work units tend to share the same perceptions of justice. They also reveal that individually produced comments reflect collective experiences in organisational justice. Further, the results indicate that problems in management and policies are often experienced in a complex way, and people making justice judgements do not separate procedural and interactional factors. RESEARCH LIMITATIONS/IMPLICATIONS: Although the commentators producing qualitative data represented many organisational hierarchy levels, the results should not be generalised to apply to horizontal, informal social relationships. PRACTICAL IMPLICATIONS: This paper gives useful information regarding challenges in human resources management in hospitals. ORIGINALITY/VALUE: The paper suggests that people making fairness judgements do not make a distinction between procedural and interpersonal factors. Instead, they use any information available to judge the righteousness of the management events. This paper serves to guide hospital managers towards a better understanding of the importance of organisational justice and its collective nature.     

Internal derangement of the temporomandibular joint: a histochemical study.

The purpose of this study was to correlate histologic findings in temporomandibular joint (TMJ) condyles and discs with their macroscopic appearance at surgery. The 24 patients with internal derangement of the joint included 20 women and 4 men (mean age, 37 years; range, 18 to 61 years). The tissue lesions varied in degree from mild soft-tissue fraying and bone remodeling to extensive resorption and new cartilage and bone formation with high phosphatase enzyme activities, and even to loss of articular soft tissue and breakdown of cortical bone. Reactions may arise in the hard tissues before they occur in the articular surface layers.     

A new monoclonal antibody against the GABA-protein conjugate shows immunoreactivity in sensory neurons of the rat.

A monoclonal antibody, 115AD5, was raised against GABA coupled to bovine serum albumin. The monoclonal antibody 115AD5 also reacted with other GABA-protein conjugates. The specificity of the monoclonal antibody was corroborated by enzyme-linked immunoassay, dot-immunobinding experiments and immunostaining of rat cerebellum sections. The monoclonal antibody 115AD5 could successfully be applied on Vibratome and cryostat sections using either indirect immunofluorescence or peroxidase techniques. In rat cerebellar cortex the monoclonal antibody 115AD5 gave an intense immunoreaction in stellate cells, in Golgi neurons, and in basket cells and their processes around Purkinje cell bodies. Purkinje cell dendrites showed GABA immunoreactivity while the cell bodies were non-reactive or only weakly reactive. There was labelling in some nuclei of Purkinje cells. GABA immunoreactivity was also found in dot-like structures in the granular layer. A large population of sensory neurons in rat thoracic and lumbar spinal dorsal root ganglia presented an intense immunoreactivity for the monoclonal antibody 115AD5. Nerve bundles immunoreactive for GABA were also seen in these ganglia. In the trigeminal ganglion, a major population of sensory neurons and some of their processes presented immunoreactivity for GABA. In the sensory nodose ganglion of the vagus nerve, many neuronal cell bodies and some fibres were immunoreactive for GABA. Ligation of the vagus nerve caudal to the ganglion resulted in an increased GABA immunoreactivity in neuronal somata of the ganglion, as well as in nerve fibres on the ganglionic side of the ligature. The present results suggest that in the rat, a population of sensory neurons in thoracic and lumbar spinal dorsal root ganglia, as well as in the trigeminal and nodose ganglia contain GABA. The presence of GABA immunoreactivity in these neurons raises the possibility of a neurotransmitter or modulator role.     

Patency of the infarct-related coronary artery — a pertinent factor in late recovery of myocardial fatty acid metabolism among patients receiving thrombolytic therapy?

The decrease in mortality among patients receiving thrombolytic therapy for myocardial infarction is greater than would be expected from the improvement in left ventricular contractile function alone; thus some additional advantage of recanalization of the infarctrelated coronary artery probably exists. Changes in the post-infarction myocardial metabolic state with respect to artery patency have not been studied with a gamma camera previously. A single-photon emission tomography scan using the fatty acid analogue para-¹²³I-iodophenylpentadecanoic acid was performed at rest before hospital discharge on nine patients with first anterior myocardial infarction. All patients had received intravenous thrombolytic therapy at the beginning of the insult. The semiquantitative analysis of the left ventricle included a total of 44 segments in each patient. The test was repeated 3 months later, with the patients divided into two groups: six patients had an angiographically patent left anterior descending coronary artery (group A), and three an occluded artery (group B). In group A the number of myocardial segments with abnormal (<70% of maximum) fatty acid uptake was initially 20.2±4.7 (mean±SD) and was reduced to 11.3±6.1 during the follow-up (95% confidence interval of the decrease 16.0–1.7 segments). In group B the number of these aberrant segments was fairly constant (21.7±13.1, initial test, and 21.3±13.3, retest). Our preliminary results suggest that even when thrombolytic therapy fails to prevent myocardial infarction, myocardial fatty acid metabolism has a better change of recovering if the relevant coronary artery has regained its patency. This finding emphasizes the need for further study to establish whether a direct link exists between myocardial metabolic state and patient survival after infarction.     

Common bile duct calculi: updated experience with dissolution with methyl tertiary butyl ether

The authors describe their experience with methyl tertiary butyl ether (MTBE) in a larger series of patients than previously reported in order to acquaint physicians with both its effectiveness for dissolution of common bile duct calculi and the limitations of its use. Ten patients with 13 biliary calculi underwent percutaneous stone dissolution treatment with the experimental cholesterol solvent, MTBE. Three stones completely dissolved within 30 minutes, seven were reduced in size, and three were visibly unaffected. All stones not completely dissolved were easily extracted by means of a stone basket except for one in a patient taken to surgery. Although MTBE perfusion is an effective technique for management of biliary calculi, practitioners should be aware that its use is quite time consuming and its odor difficult to control.     

Clinical MR imaging with a Helmholtz-type surface coil

Limited-field-of-view radio-frequency receiver antennas provide improved near-field sensitivity for magnetic resonance imaging by decreasing the antenna volume. The Helmholtz-type surface coil, consisting of two flat rings, is an organ-encompassing antenna that takes advantage of this principle to yield an improved signal-to-noise ratio (S/N). The coil was tested in a group of 50 patients and 16 healthy volunteers. Images obtained with the Helmholtz coil demonstrated quantitatively superior S/N of 2.2-fold or greater than that of comparison body coil images, as well as qualitatively superior anatomic resolution.     

Dietary fibre and fibre fractions in the diet of Finnish diabetic and non-diabetic adolescents

The intakes of total dietary fibre, water-soluble noncellulosic polysaccharides (WSNCP), water-insoluble noncellulosic polysaccharides (WISNCP), cellulose and lignins of 152 diabetic and 74 non-diabetic adolescents were studied. Food consumption data had been collected by means of two 48 h recall interviews. The diabetics obtained more total dietary fibre (33 g vs 18 g) and all fibre fractions than the controls. The fibre density of the diet was higher for the diabetics than for the controls for all meals and snacks. Positive correlations were found between total dietary fibre intake per 1000 kcal and energy-adjusted intakes of total carbohydrate, starch and most vitamins and minerals both in the diabetics and controls. A high concentration of dietary fibre in the diet thus indicated a higher general nutrient density.
