Clinical Considerations on Side-Locked Unilaterality in Long-Lasting Primary Headaches

SYNOPSIS
The relevance of side-locked unilateral pain (with no side shift) in diagnosing and differentiating primary long-lasting cephalglas such as tension headache and migraine is not clear, In the present study we have retrospectively examined the frequency of side-locked unilaterality in 1169 primary headache outpatients, whose pain duration was more than four hours. The cases were migraine (66%), tension-type headache (21%) and non-classifiable headache and atypical facial pain (not well defined headache) (13%). The occurrence of side-locked unilateral pain was more frequent in migraine (17%) than tension headache (4%). However side-locked pain was found to be more frequent in patients with not-well-defined head pain (28%). Of the 1169 patients, 181 (15%) had side-locked unilateral pain: 70% of the 181 had migraine, 25% were not-well-defined head pain cases and 5% were tension-type headache cases. The high percentage of migraine cases in the side-locked unilateral group reflects the high proportion of migraine patients in the studied population.     

Cluster Headache Patients'' Responses to Dexamethasone Suppression Test

SYNOPSIS
The recurrent or cyclic time pattern is one of the most characteristic features of the Cluster Headache (CH) syndrome.
This observation has led to many studies which have proposed that the central hypothalamic system possibly plays a role in the pathogenesis of Cluster Headache attacks.
In this study we utilized the Dexamethasone Suppression Test in order to test the functioning of the hypothalamo-pituitary axis in CH patients, in the headache-free state.
We were able to ascertain that the hypothalamo-pituitary axis functioned normally, while the base-line cortisol levels of Cluster Headache patients appeared higher than the levels found in the control subjects.     

Insulin resistance after surgery: normalization by insulin treatment

1. Injury is known to be associated with variable degrees of tissue insensitivity to insulin. We measured insulin resistance in a group of non-obese, glucose-tolerant patients undergoing major elective surgery with an uncomplicated post-operative course. 2. Shortly after surgery, hyperglycaemia (7.3 +/- 0.6 versus 4.2 +/- 0.3 mmol/l glucose pre-surgery, mean +/- SEM, P less than 0.01) with normal insulin concentrations (73 +/- 15 versus 64 +/- 18 pmol/l) suggested the presence of insulin resistance. Counter-regulatory hormones were raised, whole-body protein oxidation was doubled (P less than 0.01) and energy expenditure was up by 18% (P less than 0.01). 3. Insulin sensitivity was quantified by clamping plasma glucose concentrations at 5.6 mmol/l during 24 h of total parenteral nutrition (15% protein, 55% glucose and 30% fat, supplying 1.25 times the measured resting energy expenditure) with a variable infusion of exogenous insulin. After surgery, eight times more insulin was needed than before surgery (14.14 +/- 1.15 versus 1.78 +/- 0.29 pmol min-1 kg-1, P less than 0.001) to maintain euglycemia. 4. After surgery, stimulation of net carbohydrate oxidation (18.8 +/- 1.4 versus 17.2 +/- 1.8 mumol min-1 kg-1 preoperatively, not significant), suppression of lipolysis and lipid oxidation and inhibition of ketogenesis occurred to the same extent as before surgery. Of the infused nutrients, the glucose was all oxidized, amino acids replaced endogenous protein losses (= neutral nitrogen balance) and lipids were stored. Insulin administration caused no further increment in oxygen consumption or energy expenditure.(ABSTRACT TRUNCATED AT 250 WORDS)

Headache,eating and sleeping behaviors and lifestyle factors in preadolescents and adolescents: preliminary results from an Italian population study

Several dietary and lifestyle habits can be associated with headaches or with their progression to chronic forms in adults. We report the results of the first population study performed in Italy on a sample of preadolescent and adolescent students to assess the possible association between headache and specific habits and lifestyle factors. Preliminary data from 800 questionnaires showed that 365 subjects had headaches, which were of moderate–severe intensity, associated with anorexia, and caused absence from school in more than 50 % of students. The main finding was the evidence of a clear association between headache and irregular intake of meals (especially irregular breakfast) and sleep disturbance with significant differences when subjects with and without headache were compared. If confirmed, these results are likely to influence clinical practice as well to address educational programs in preadolescents and adolescents.     

A prospective,observational study of the safety and effectiveness of intramuscular psychotropic treatment in acutely agitated patients with schizophrenia and bipolar mania

This naturalistic, observational pan-European study assessed the safety and early effectiveness of intramuscular (IM) psychotropic treatments in patients with acute agitation suffering from schizophrenia or bipolar mania. One thousand nine hundred and forty of 1945 patients completed the 24-hour observation period after initial IM treatment. Patients from 12 European countries were included (mean age 39 years; 58% male, 66% schizophrenia). IM treatment was at the physician's discretion. The primary objective was to describe the acute tolerability of IM psychotropic therapies in clinical practice, with particular emphasis on EPS. At baseline, 68% of the patients received IM monotherapy, with IM olanzapine most commonly prescribed (36%). During the first 24 hours, 190 (9.8%) patients experienced EPS. The occurrence of EPS was statistically significantly lower in patients treated with IM olanzapine compared to those treated with other IM psychotropic medications (mainly typical antipsychotics and benzodiazepines): acute dystonia: 1.1%, 95% CI 0.5–2.3 and 2.9%, CI 2.0–4.0; akathisia: 2.3%, CI 1.3–3.7 and 5.5%, CI 4.3–6.9; Parkinsonism: 2.9%, CI 1.8–4.4 and 7.8%, CI 6.4–9.4, respectively. Anticholinergic treatment was given to 12% IM olanzapine versus 31% non-olanzapine treated patients. Acute agitation after 24 hours was reduced by 1.68 (95% CI 1.46–1.91) points on the Clinical Global Impression of Severity (CGI-S) in IM olanzapine patients and 1.51 (95% CI 1.30–1.73) points in non-olanzapine patients. Additional psychotropic medication was required for 90% of the patients during the first 24 hours of treatment. Results provide naturalistic evidence for low EPS rates and improvement of agitation with IM psychotropic medications during acute states of patients suffering from acute mania or schizophrenia.     

A multicenter cross sectional study on bone mineral density in rheumatoid arthritis. Italian Study Group on Bone Mass in Rheumatoid Arthritis

OBJECTIVE: To determine the frequency of osteoporosis in a large cohort of women with rheumatoid arthritis (RA) and to investigate the main determinants of bone mineral density (BMD) and risk factors for vertebral fractures in this population. METHODS: We recruited 925 consecutive female patients with RA at 21 Rheumatology Centers in Italy. For each patient pre-registered demographic, disease, and treatment-related variables were collected. BMD was measured at lumbar spine and proximal femur by dual x-ray absorptiometry technique. Collected variables underwent a univariate and multivariate statistical procedure. Osteoporosis was defined as BMD > -2.5 T score. RESULTS: The frequency of osteoporosis in the whole sample was 28.8% at lumbar spine and 36.2% at femoral neck and increased linearly from Steinbrocker's functional stage I to IV (p = 0.0001). Patients with spinal or femoral osteoporosis were significantly older (p = 0.0001), had a lower body mass index (BMI) (p < 0.02), a significantly longer disease duration (p < 0.02) and a significantly higher Health Assessment Questionnaire (HAQ) score (p = 0.0001). These differences were significant, even after adjusting for age. Steroid use was associated with significantly lower lumbar and femoral BMD (p = 0.0001) even after adjusting for the main confounding covariates. Analysis of lateral spine radiographs revealed 74 women with at least one vertebral fracture. These women had a significantly lower lumbar and femoral BMD (p = 0.0001). The generalized linear model showed that steroid use, menopause, BMI, age, and HAQ were all significant independent predictors of lumbar and femoral BMD. The logistic procedure showed that age (OR 1.05, 95% CI 1.03-1.07), HAQ (OR 1.3, 95% CI 1.07-1.7), menopause (OR 1.9, 95% CI 1.1-3.2), use of steroids (OR 1.5, 95% CI 1.07-2.1), and BMI (OR 0.8, 95% CI 0.8-0.9) were significantly associated with the risk for osteoporosis. The only variables associated with an increased risk for vertebral fracture were age (OR 1.04, 95% CI 1.01-1.08), HAQ (OR 1.7, 95% CI 1.08-2.09), and cumulative steroid intake (OR for 1 g of prednisone 1.03, 95% CI 1.006-1.07). CONCLUSION: To prevent osteoporosis and its dramatic complications in RA the therapeutic challenge is to preserve functional capacity using the lowest possible dosage of corticosteroids.
