The patient was a 7-year-old girl with early onset urticarial cutaneous lesions and was later complicated with aseptic meningitis. Her skin lesions occurred in the infantile period and were diagnosed as urticaria, but did not disappear with antihistamines and were recurrent and persistent. In addition, she had experienced an episode of headache about once a month since 1991, when she was 4 years old, and was diagnosed as aseptic meningitis. All studies including skin biopsy for urticarial vasculitis (UV) and systemic lupus erythematosus (SLE) were negative except for the data from non-specific inflammations. A systemic corticosteroid therapy dramatically reduced her symptoms. An unusual clinical course for this patient is described. It might suggest that this case is a presentation of the disease entity of UV, chronic urticaria and possibly SLE. To our knowledge, a similar case has not been previously reported. 相似文献

Recently, it has come to be accepted that the result of the tilt test is specific to neurally mediated syncope (vasovagal syncope). Only rarely is a case of paroxysmal atrial fibrillation without any organic diseases in childhood reported. A case reported here of a 14-year-old boy with neurally mediated syncope; which was complicated by paroxysmal atrial fibrillation, and which was diagnosed by performing the tilt test. Atrial fibrillation can be induced by the extraordinary stimulation of the vagal nerve during syncope. In a child, neurally mediated syncope complicated with paroxysmal atrial fibrillation has not been previously reported. 相似文献

Interleukin-6 functions as an autocrine growth factor in a cholangiocarcinoma cell line 总被引:1,自引:0,他引:1

Abstract The tumour cells of a human cholangiocarcinoma cell line, HuCC-T1, were found to express mRNA of interleukin-6 (IL-6) and to secrete a large amount of biologically active IL-6 in the culture medium at the concentration of 22.6 ng/mL. Interleukin-6 was demonstrated in the cytoplasm of the cells by immunohistochemical staining. Furthermore, these cells showed the presence of receptors for IL-6 on the surface, and DNA synthesis of the cells was stimulated by the exogenous addition of recombinant human IL-6 into the culture medium. The cell growth was significantly inhibited in the presence of anti-human IL-6 antibody in the culture medium. These findings indicate that IL-6 is one of the autocrine growth factors of this cell line in vitro. 相似文献

TdP is a serious complication of AV block. We report a case of complete AV block with QT prolongation who had bouts of TdP resistant to lidocaine and isoproterenol. Temporary pacing could not be performed, because insertion of a pacing lead triggered TdP that deteriorated into ventricular fibrillation. Nicorandil, a potassium channel opener, shortened the QT interval and abolished TdP. This may suggest that potassium channel opening drugs are clinically effective against TdP associated with bradycardia-dependent QT prolongation. 相似文献

Radiofrequency (RF) catheter ablation of supraventricular tachycardias causes local parasympathetic denervation. This study used heart rate variability (HRV) to evaluate the effects of ablation of atrial tachycardia (AT) arising from the atrioventricular annulus (AVAT) on autonomic function. Ten patients with AVAT were referred for ablation (group AT) and compared with 8 patients with paroxysmal atrial fibrillation who underwent PV isolation (group Paf), and 13 patients with idiopathic ventricular tachycardia successfully treated by ablation (group VT). Time and frequency domain analysis of HRV on 24-hour ambulatory ECG recordings was performed before and after ablation. Root mean square of differences of consecutive N-N intervals (rMSSD), percentage of difference between consecutive N-N intervals >50 ms (pNN50), and high frequency (HF) component were measured to examine the effects on parasympathetic nerve activity. In group AT, rMSSD, pNN50, and HF decreased significantly after ablation, while they remained unchanged in group Paf and group VT. These observations suggest that parasympathetic denervation after ablation was limited to group AT, and depended on the site of energy delivery along the tricuspid or mitral valve as opposed to atrial or ventricular muscle. 相似文献

A 65-year-old female received recombinant interferon (IFN) α-2b daily for the treatment of chronic hepatitis C. Fever (39°C or higher) developed 14 days after the start of administration. Abdominal computed tomography suggested multiple liver abscesses, which had not been detected before IFN administration. An autopsy revealed an amoebic liver abscess. A subclinical infection of Entamoeba histolytica in this case developed into amoebic liver abscess during IFN administration. 相似文献

Monoclonal anti CD36 antibodies capable of inhibiting platelet adhesion to collagen have not previously been identified. We have now prepared two groups of monoclonal antibodies. One group was prepared using, as immunogen, highly purified (99+%) CD36 prepared by a denaturing procedure. These antibodies (Mo series) reacted strongly with CD36 on protein blots but did not immunoprecipitate native CD36 from platelet lysates nor inhibit platelet adhesion to collagen. The second group of monoclonal antibodies (131 series) was prepared using CD36 purified to >95% by a non-denaturing procedure. These antibodies reacted with control platelets, but not Naka -negative platelets which lack CD36, as measured by flow cytometry and by immunoprecipitation. Three monoclonal antibodies of this latter group (131.4, 131.5 and 131.7) inhibited platelet adhesion to collagen in static systems under Mg2+ -independent conditions but had little effect in the presence of Mg2+ . 131.4 and 131.7 also inhibited adhesion to collagen using citrated whole blood in a parallel plate flow chamber at physiological shear rates (800 s−1 ), whereas 131.5 was without effect. These are the first anti-CD36 monoclonal antibodies shown to be capable of inhibiting platelet adhesion to collagen and provide further evidence that CD36 plays a role in platelet–collagen interaction. 相似文献

Robotic devices for therapy have the potential to enable intensive, fully customized home rehabilitation over extended periods for individuals with stroke and traumatic brain injury, thus empowering them to maximize their functional recovery. For robotic rehabilitation to be most effective, systems must have the capacity to assign performance goals to the user and to increment those goals to encourage performance improvement. Otherwise, individuals may plateau at an artificially low level of function. Frequent goal change is needed to motivate improvements in performance by individuals with brain injury; but because of entrenched habits, these individuals may avoid striving for goals that they perceive as becoming ever more difficult. For this reason, implicit, undetectable goal change (distortion) may be more effective than explicit goal change at optimizing the motor performance of some individuals with brain injury. This paper reviews a body of work that provides a basis for incorporating implicit goal change into a robotic rehabilitation paradigm. This work was conducted with individuals without disability to provide foundational knowledge for using goal change in a robotic environment. In addition, we compare motor performance with goal change to performance with no goal or with a static goal for individuals without brain injury. Our results show that goal change can improve motor performance when participants attend to visual feedback. Building on these preliminary results can lead to more effective robotic paradigms for the rehabilitation of individuals with brain injury, including individuals with cerebral palsy. 相似文献

A girl, 5.7 years old, gained tolerance to egg white ingestion in spite of high immunoglobulin E (IgE) antibody titers to egg white but retained contact urticaria against egg white. She developed atopic dermatitis on her face at 2 months of age and showed high IgE antibody titers to egg white and cow's milk. Accidental ingestion of egg products initiated immediate symptoms such as wheezing, urticaria, erythema and edema of the eyelids and conjunctiva three times. These symptoms were confirmed by challenge tests using boiled egg white at 3.9 years of age. She also reacted positively to a 20 min patch test on her volar arm with raw egg white. However, there were no reactions to the oral challenge test by boiled egg and freeze-dried egg white at 5.1 and 5.7 years of age, respectively. This non-responsiveness was confirmed by a double-blind, placebo-controlled food challenge using freeze-dried egg white. Nevertheless, she showed positive reactions to a 20 min patch test with freeze-dried egg white. Her IgE antibody titers to the egg white components including ovomucoid, ovalbumin, ovotransferrin and lysozyme as well as egg white were high from 2.9 to 5.7 years old. Her IgE antibody titers for the ovomucoid fragments digested by pepsin, chymotrypsin and trypsin were not lower than those of positive control subjects. The binding activity of IgE antibody to ovomucoid, however, decreased from 2.9 to 5.6 years as shown by radioallergosorbent test (RAST) inhibition assays. The IgE antibody showed weaker binding activity to pepsin- and chymotrypsin-digested ovomucoid that were filtered through cut-off 10 000 filter at the age of 2.1 and 5.7 years. We speculated that the maturation of secretion of digestive enzymes was involved in the mechanisms of the acquisition of tolerance to egg white ingestion in spite of the persistence of contact urticaria. 相似文献
