Practical guidelines for physicians in the management of febrile seizures

Recent studies have shown that adequate medication can prevent the recurrence of febrile seizures (FS). It has also been clarified that the vast majority of, though not all, FS patients follow a benign course. Then, questions arise as to whether or not FS should be prevented, particularly in light of the risks of side effects from drugs. Which kinds of FS can be prevented, if necessary? The guidelines presented here are aimed primarily at helping general practitioners in considering how to manage FS most appropriately. The guidelines stress that judgements should be individualized, while referring to a few specific ‘warning factors’. The guidelines follow a ‘laissez-faire’ principle for the majority of FS cases, whereas intermittent therapy with diazepam and continuous medication with either phenobarbital or valproate are indicated in other limited cases meeting respective definite criteria.     

Overexpression of suppressor of cytokine signalling-5 augments eosinophilic airway inflammation in mice

BACKGROUND: Enhanced expression of the suppressor of cytokine signalling (SOCS)-5 might be of therapeutic benefit for T-helper type 2 (Th2) dominant diseases, as its expression is reported to result in a reduction of Th2 differentiation in vitro due to the inhibition of IL-4 signalling. OBJECTIVE: To investigate the regulatory role of SOCS-5 in vivo, we explored the phenotype of an experimental asthma model developed in SOCS-5 transgenic (Tg) mice. METHODS: The SOCS-5 Tg mice or wild-type (WT) mice were sensitized and repeatedly challenged with ovalbumin (OVA). We examined bronchoalveolar lavage fluid (BALF), lung specimens, and airway hyperresponsiveness (AHR) to methacholine. RESULTS: The production of IFN-gamma by CD4(+) T cells from unprimed SOCS-5 Tg mice was significantly increased in comparison with unprimed wild-type mice, indicating that SOCS-5 Tg mice have a Th1-polarizing condition under natural conditions. However, in an asthma model, significantly more eosinophils in the airways and higher levels of IL-5 and IL-13 in BALF were observed in the SOCS-5 Tg than the wild-type mice. AHR in the asthma model of SOCS-5 Tg was also more enhanced than that of wild-type mice. OVA-stimulated CD4(+) T cells from the primed SOCS-5 Tg mice produced significantly more IL-5 and IL-13 than CD4(+) T cells from wild-type mice. CONCLUSION: Our results demonstrate that the overexpression of SOCS-5 does not inhibit Th2 response, but rather augments the phenotype of the asthma model in vivo. This finding throws into question the therapeutic utility of using enhancement of SOCS-5 expression for Th2-dominant disease.

抑郁发作自杀未遂患者脑源性神经营养因子水平及其相关因素研究

Objective To investigate the possible role of brain-derived neurotrophic factor(BDNF)in the pathophysiology of attempted suicide in depressive episode patients.Methods The subjects were 23 depressive episode patients who had recently attempted suicide.24 depressive episode patients without suicide attempt.and 30 sex-age-and education matched healthy controls.The Hamihon Depression Rating Scale-24 items(HAMD24),Beck Helpless Rating Scale(BHS)and Self-rating Idea of Suicide Scale (SIOSS)was used to evaluate the severitv of symptoms.The seruln level of BDNF was detected with sandwich ELISA.Pearson correlation coefficients wag used to measure the correlations between serum BDNF and the related illness variables.Results There were significant difierences in the serum level of BDNF between patients with attempted suicide,pailents without suicide attempt and normal controls(F=21.927,P＜0.05).Post hoc analysis showed the serum BDNF levels in patients with attempted suicide [(57 ±16)ng/L]were lower than that in patients without[(75±28)ns/L;P＜0.05],and were lower in patients without suicide attempt[(75 ±28)ng/L]than that in normal controls[(111 ±39)ng/L;P＜0.01].In patients with attempted suicide,the serum BDNF was negatively correlated to the duration of depressive episode(r=-0.541,P=0.008),the mean BHS score(r=-0.494,P=0.017)and the mean SIOSSscore(r=-0.754.P=0.000).Conclusion The results suggest that the decreased serum brain-derived neurotrophic factor is related to the pathophysiology of attempted suicide in depressive episode patients.     

Comparing hand-held computers and paper diaries for haemophilia home therapy: a randomized trial

Treatment of severe haemophilia with factor concentrates is by self-infusion in the home. Adherence to record keeping on paper diaries is poor. A randomized-controlled trial compared adherence with record keeping of paper diaries with hand-held computers. Forty-one individuals with severe haemophilia, were randomized to hand-held computers (n = 22) or paper diaries (n = 19) and followed for 6 months. About 86.2% (679 of 788) of infusions by patients in the computer group were in compliance with the data submission schedule compared with only 48.3% (358 of 741) of infusions by patients using paper diaries (P < 0.0001). The time intervals between infusions and the receipt of data were shorter in the computer group (median 0.25 vs. 25 days respectively, P < 0.0001). Reminder phone calls by the clinic were made less frequently to users of hand-held computers than to users of paper diaries (median one vs. five times, P < 0.0001). Accuracy of data was similar for both methods. Compliance with hand-held computers was superior to paper diaries. The clinic received data from hand-held computers mostly on the same day, and nurses could thereby provide clinical advice more effectively. Although hand-held computers did not result in increased accuracy, errors could be detected and corrected more rapidly. Electronic data can more easily be verified, analysed and summarized than that from paper diaries.
