Discrimination of idiopathic pain syndromes from neurogenic pain syndromes and healthy volunteers by means of clinical rating,personality traits,monoamine metabolites in CSF,serum cortisol,platelet MAO and urinary melatonin

Summary The aim of the present study was to investigate the discriminative power of a series of variables (including determination of depressive symptomatology by means of a visual analogue scale, determination of personality traits by means of the Karolinska Scales of Personality, determination of monoamine metabolites in CSF, platelet MAO activities, serum cortisol before and after dexamethasone suppression and urinary melatonin) in differentiating (a) chronic pain patients from healthy subjects, and (b) patients with idiopathic pain syndromes from patients with neurogenic pain syndromes. Separately each of the measures gave a significant but often low contribution to the discrimination, while a combination of several measures gave a complete discrimination both between healthy subjects and patients with chronic pain syndromes and between patients with idiopathic and neurogenic pain syndromes, respectively.Supported in part by grants from the Swedish Medical Research Council (grants no. 3371, 4145 and 5740) and by a grant from Stiftelsen Söderström-Königska Sjukhemmet

The value of scintigraphy in hips with slipped capital femoral epiphysis and the value of radiography and MRI after 10 years

Preoperative bone scintigraphy of the femoral head in 33 hips with slipped capital femoral epiphysis, showed no relation to duration of symptoms or degree of slip. The preoperative uptake was always normal or increased. Two hips had postoperative femoral head uptake below normal, both had complications affecting the vascular supply, resulting in necrosis of the femoral head and severe arthrosis. At follow-up after 10 (5-15) years of 28 hips, no relation could be demonstrated between Adolescent Hip Questionnaire which included clinical data, and radiography or magnetic resonance imaging. We only recommend scintigraphy after complications jeopardizing the vascular supply of the femoral head in slipped capital femoral epiphysis.     

Daptomycin: a novel cyclic lipopeptide antimicrobial.

PURPOSE: The development, activity, pharmacokinetics, pharmacodynamics, clinical efficacy, adverse effects, and dosage and administration of daptomycin are reviewed. SUMMARY: Daptomycin, a novel cyclic lipopeptide antimicrobial, is bactericidal against a range of gram-positive bacteria, including many multiple-drug-resistant isolates. It has only minimal activity against anaerobic bacteria and no activity against gram-negative bacteria. Daptomycin exhibits linear pharmacokinetics, and the plasma concentration-versus-time relationship is best described by a two-compartment model with first-order elimination. The initial bactericidal activity is rapid, extensive, and concentration related. In clinical trials, daptomycin has shown efficacy in treating complicated skin and skin-structure infections (CSSSIs); the drug carries FDA-approved labeling for same. The adverse effects of daptomycin appear comparable to those of vancomycin and semisynthetic penicillins. The dosage for CSSSIs is 4 mg/kg by i.v. infusion every 24 hours. CONCLUSION: Daptomycin is bactericidal against gram-positive organisms and offers an option in the treatment of CSSSIs.     

Use of the burn intervention score to calculate the charges of the care of burns

Background

To our knowledge this is the first published estimate of the charges of the care of burns in Sweden. The Linköping Burn Interventional Score has been used to calculate the charges for each burned patient since 1993. The treatment of burns is versatile, and depends on the depth and extension of the burn. This requires a flexible system to detect the actual differences in the care provided. We aimed to describe the model of burn care that we used to calculate the charges incurred during the acute phase until discharge, so it could be reproduced and applied in other burn centres, which would facilitate a future objective comparison of the expenses in burn care.

Development of Clinical Pharmacology as a Medical Speciality in Europe – The Roles of WHO,IUPHAR and EACPT

This MiniReview shows that both WHO and IUPHAR very early recognized that there is a gap between the availability of academic expert knowledge in pharmacology and its utilization in health care. Many initiatives have been taken to bridge this gap, but still 12 European countries do not recognize clinical pharmacology as a medical speciality because the profession has failed to develop defined functions in patient care. A first priority for EACPT therefore ought to be to promote clinical pharmacology as a medical speciality recognized by the European Union. The pharmacological services listed in Table 7 that focus on drug problems agree well with those that were recently prioritized in the IUPHAR/WHO/CIOMS manifesto to correct a major weakness in the health care of today in order to promote rational use of drugs.     

An Interprofessional Rural Health Education Program

Objectives. To develop, implement, and assess an interprofessional rural health professions program for pharmacy and medical students.Design. A recruitment and admissions process was developed that targeted students likely to practice in rural areas. Pharmacy students participated alongside medical students in completing the Rural Health Professions program curriculum, which included monthly lecture sessions and assignments, and a capstone clinical requirement in the final year.Assessment. Fourteen pharmacy students and 33 medical students were accepted into the program during the first 2 years of the Rural Health Professions program. Approximately 90% of the rural health professions students were originally from rural areas.Conclusions. The rural health professions program is an interprofessional approach to preparing healthcare providers to practice in rural communities.     

Role of histamine release in nonspecific vasodilatation during anodal and cathodal iontophoresis

Nonspecific vasodilatation during iontophoresis is an important confounding factor in experimental pharmacology. In this investigation, we studied the involvement of sensory nerves and histamine-related reactions in causing nonspecific vasodilatation in a model of anodal and cathodal iontophoresis of sodium chloride. Firstly, we applied a mixture of local anesthetic (EMLA) cream to confirm its suppressive effect on nonspecific vasodilatation and to measure its efficacy in three different dosages (duration: 1, 2, and 3 h). We then investigated the role of histamine in nonspecific vasodilatation by giving an oral antihistamine drug (cetirizine) to subjects who had and had not been given EMLA. We found substantial suppression of the nonspecific vasodilatation in all EMLA-treated groups (all dosages) compared with untreated controls (with suppression rates of 60-65%). Dosage had no significant effect. A further suppression of nonspecific vasodilatation was seen after oral cetirizine during anodal and cathodal iontophoresis in both EMLA-treated and untreated groups. The antihistamine effect was most pronounced during anodal iontophoresis. These results suggest a histaminergic increase in perfusion that may be independent of neurogenic mechanisms and depend on polarity (anode or cathode). Local nerve blocks (EMLA) together with cetirizine may therefore be used to reduce nonspecific vasodilatation in both anodal and cathodal iontophoresis.     

Jejunal secretion of secretory immunoglobulins and gliadin antibodies in celiac disease

The aim of this study was to determine the secretion of secretory immunoglobulins and gliadin antibodies in the small bowel in celiac disease. Twenty-four patients were investigated by perfusion of a defined jejunal segment. Four of the patients studied had a serum IgA deficiency and had no measurable amounts of secretory IgA in the perfusion fluid. The other patients demonstrated a significant increase in the jejunal concentration of secretory IgA (median 28.5 mg/liter) compared with healthy controls (median 16 mg/liter,N=16) and of IgM, celiac (median 12.3 mg/liter) compared to healthy controls (median 6.8 mg/liter,N=16). Jejunal IgA gliadin antibodies were detected in all patients except those with an IgA deficiency. All patients had jejunal IgM gliadin antibodies, but none of the patients had measurable jejunal IgG gliadin antibodies. A positive correlation was detected between serum and jejunal IgA gliadin antibody levels in the celiac patients, (P<0.01). Calculation of the ratio between gliadin antibodies and total levels of IgA and IgM in serum and jejunal perfusate demonstrated that the jejunal synthesis of gliadin antibodies of IgA and IgM type is both more pronounced and persistent than the systemic humoral immune response to gliadin.This work was supported by grants from the Swedish Medical Research Council, the Swedish Life Insurance Companies' Trust for Medical Research, and Th.C.
