Symptoms of classic migraine attacks: Modifications brought about by metoprolol

There is little information available concerning whether, and to what extent, migraine-prophylactic agents interfere with the symptoms of migraine attacks. The present study is a placebo-controlled, double-blind study concerning metoprolol in classic migraine. The data refer to the symptoms of single migraine attacks. During metoprolol treatment more attacks were characterized as mild (p = 0.002), and mean global rating (an integrated estimate of headache intensity and of other discomfort) was lower (4.2 versus 5.2, p = 0.003). The mean headache intensity per attack (1.97 versus 2.15) and the mean duration (5.5 versus 6.8 h) were not significantly different. Consumption of analgesics per attack was lower during metoprolol treatment (0.6 versus 1.1; p = 0.02). Attacks with associated symptoms accompanying the headache were fewer during metoprolol treatment (p = 0.014). Total visual and non-visual aura symptoms occurred with similar frequency, but scintillations and paraesthesia were more frequent during metoprolol treatment, whereas speech disturbances were less frequent. In spite of lower consumption of analgesics, the symptoms appeared milder during metoprolol than during placebo. The pattern of changes indicates that metoprolol exerts its action via the sympathetic nervous system; peripheral vasoconstriction is hardly the underlying mechanism of action.     

Compliance with antibiotic prophylaxis in urinary tract infection

Compliance with antibiotic prophylaxis after urinary tract infection was assessed in 32 children, using a parent questionnaire, and a urine test for antibacterial substances. In 31 (97%) cases, parents reported giving the antibiotics every day but only 22 (69%) of urine tests were positive. Failure to understand the reasons for prophylaxis and non-compliance were significantly associated.     

A Toddler Parenting Intervention in Primary Care for Caregivers With Depression Symptoms

Caregiver depression impacts parenting behaviors and has deleterious effects on child behavior. Evidence-based interventions to address parenting have not been adapted for use with depressed caregivers in pediatric primary care settings. Our study examined the feasibility and explored outcomes of an evidence-based parenting program implemented in primary care and adapted for caregivers with depressive symptoms caring for toddlers. We conducted a randomized controlled trial with a wait-list control. Participants were caregivers who screened positive for depressive symptoms in pediatric settings with a toddler. Our study was implemented from July 2011 to June 2012. We adapted the Incredible Years Parents, Babies and Toddlers program with the addition of depression psychoeducation (12 weekly sessions), and assessed caregivers at baseline and immediately post-intervention. We assessed participation rates, depressive symptoms, parenting discipline practices, social support, and parenting stress. Our results revealed that 32 caregivers participating in the intervention group had significantly greater improvement in self-reported parenting discipline practices compared to the 29 wait-list control group caregivers. We found no differences between groups in depressive symptoms, social support, or parenting stress. Our study demonstrated that the average attendance was poor (mean attendance = 3.7 sessions). We adapted an evidence-based parenting intervention for caregivers with depressive symptoms and toddlers in primary care; however, participation was challenging. Alternative intervention strategies are needed to reach and retain low-income caregivers with depression symptoms as they face multiple barriers to participation in groups within center-based services.

The value of one hour daytime sleep recording in the diagnosis of the sleep apnoea syndrome

In this study we investigated whether the diagnosis of sleep apnoea syndrome (SAS), based on night-time polysomnography (NPSG), can be predicted or excluded by a one-hour daytime polysomnography (DPSG). The results of 306 NPSGs were compared with DPSGs, which were performed the day before. Treated patients were excluded. In the 89 patients with SAS (Apnoea index (AI)>/=5) 59 showed apnoeas during the DPSG and 30 did not. In the 217 without SAS 25 showed apnoeas daring DPSG and 192 did not. Sensitivity for detecting SAS was 66%, the specificity was 88%, the positive predictive value (PPV) 70% and the negative predictive value (NPV) 86%. For relevant SAS (AI>/=10) the NPV would be 95%. We conclude that the one-hour DPSG is not sufficient for diagnosing or excluding SAS with certainty. It can be used to make the presence of relevant SAS unlikely.     

Assessment of feeding different amounts of arachidonic and docosahexaenoic acids in preterm infant formulas on the fatty acid content of lipoprotein lipids

This study evaluated preterm infants of less than 2.3 kg birth weight fed commercial formula (Preemie SMA^®) devoid of arachidonic acid (AA) and docosahexaenoic acid (DHA) and compared this control group with similar infant groups fed one of three formulas containing a range of 0.32-1.1% AA and 0.24-0.75% DHA in the fat component of the formula. An analogous group of infants fed on their mothers' breast milk and a breast milk fortifier was also studied. Individual lipoprotein fractions were isolated from blood samples collected at 12 d of age and after a further 4 wk of feeding. The fatty acid content of individual lipid components, isolated from each lipoprotein fraction was quantitatively determined in order to identify change in marker pools of essential fatty acid. The high density lipoproteins (HDL) and low density lipoproteins (LDL) phospholipid and cholesterol ester fractions contain most of the AA and DHA found in the lipoprotein fractions (total of 0.49% and 0.35%, respectively). Infants fed a formula without AA and DHA showed a reduction in AA level in the phospholipid fraction of all lipoproteins and in the HDL and LDL cholesterol ester fraction. A reduced level of DHA was also observed primarily in the lipoprotein phospholipid fraction in comparison with infants fed breast milk or infant formula containing AA and DHA. Supplementing infant formula with increasing levels of AA and DHA produced a clear dose response in the level of AA found in the HDL and LDL phospholipid fraction. From comparison of the fatty acid levels present in the lipoproteins it appears that a formula level of 0.49% AA and 0.35% DHA provides sufficient levels of these fatty acids to achieve a similar fatty acid content to that of infants fed breast milk for the major lipoprotein fractions examined.     

Early recurrence or persistence of autoimmune diseases after unmanipulated autologous stem cell transplantation

Autologous stem cell transplantation with or without in vitro lymphocyte depletion has been suggested as a new treatment option for severe autoimmune diseases. We describe five patients with autoimmune diseases (CREST syndrome, myasthenia gravis and Hashimoto's thyroiditis, systemic lupus erythematosus, atopic dermatitis, and rheumatoid arthritis) who underwent autologous bone marrow (n = 1) or peripheral blood progenitor cell (n = 4) transplantation with unmanipulated grafts as treatment for the autoimmune disease in one case or as treatment for a malignant disorder with a concomitant autoimmune disorder in four cases. In all patients serological and clinical signs of the autoimmune disease recurred early or persisted. These observations should be regarded as a cautionary note concerning the efficacy of high-dose therapy followed by transplantation of unmanipulated autologous stem cells for treatment of severe autoimmune diseases.
