The current treatment approach for severe aplastic anemia in children is based on studies performed in the 1980s, and updated evidence is required. We retrospectively compared the outcomes of children with acquired severe aplastic anemia who received immunosuppressive therapy within prospective trials conducted by the Japanese Childhood Aplastic Anemia Study Group or who underwent bone marrow transplantation from an HLA-matched family donor registered in the Japanese Society for Hematopoietic Cell Transplantation Registry. Between 1992 and 2009, 599 children (younger than 17 years) with severe aplastic anemia received a bone marrow transplant from an HLA-matched family donor (n=213) or immunosuppressive therapy (n=386) as first-line treatment. While the overall survival did not differ between patients treated with immunosuppressive therapy or bone marrow transplantation [88% (95% confidence interval: 86–90) versus 92% (90–94)], failure-free survival was significantly inferior in patients receiving immunosuppressive therapy than in those undergoing bone marrow transplantation [56% (54–59) versus 87% (85–90); P<0.0001]. There was no significant improvement in outcomes over the two time periods (1992–1999 versus 2000–2009). In multivariate analysis, age <10 years was identified as a favorable factor for overall survival (P=0.007), and choice of first-line immunosuppressive therapy was the only unfavorable factor for failure-free survival (P<0.0001). These support the current algorithm for treatment decisions, which recommends bone marrow transplantation when an HLA-matched family donor is available in pediatric severe aplastic anemia. 相似文献

Background
Mycoplasma pneumoniae pneumonia (MPP) is generally a self-limiting disease, but it may become refractory. It is thought that refractory MPP is linked to the excessive immunologic responses of the host. Consequently, the use of adjunctive systemic corticosteroids may have beneficial effects. In this study, we compared the effects of high- and low-dose corticosteroid therapy in a pediatric population with refractory MPP.Methods
We retrospectively collected data from 91 pediatric MPP patients treated with adjunctive systemic corticosteroids between April 2014 and October 2016. The patients were divided into the following two groups: high-dose corticosteroid group (2 mg/kg/day or more of prednisolone equivalents; n = 38) and low-dose corticosteroid group (<2 mg/kg/day; n = 53). Additionally, we compared the number of febrile days post-corticosteroid administration. We used 25 paired patients in a propensity score matching analysis to correct for confounding factors both by age and by days (from onset till corticosteroid therapy initiation).Results
We observed that in the high-dose corticosteroid group defervescence following corticosteroid therapy initiation was achieved significantly earlier and length of hospitalization was significantly shorter (0.8 ± 1.0 vs. 1.5 ± 1.4 days and 8.2 ± 2.4 vs. 10.7 ± 2.7 days, respectively). In the propensity score matching, we observed that significant differences in the length of fever following corticosteroid therapy initiation and hospitalization were still present. Further, neither of the groups developed corticosteroid-related adverse events.Conclusion
Our results suggest that patients with refractory MPP treated with high-dose corticosteroid could achieve defervescence earlier and have a shorter hospitalization. 相似文献75.
Carbamylcholine binding was determined from competition experiments with [3H] quinuclidinyl benzilate in the rat brain chronically treated with nicotine. The nicotine group exhibited about two-fold lower affinity for the agonist binding toward a high-affinity site (or state) in the cerebral cortex, as compared with the control group. However, no alteration in the agonist binding was observed in the hypothalamus/thalamus and brainstem after chronic nicotine treatment. 相似文献

Fucosidosis is a rare autosomal recessive disorder resulting from a deficiency of α-L-fucosidase. Recently, various mutations
have been reported in this disease, but it is difficult to elucidate the phenotype from the genetic mutations. We report a
patient with chronic infantile type fucosidosis, with a compound heterozygote of a nonsense mutation (W148X, Trp at codon
148 to stop codon) and a large deletion, including all exons. This is the first report of a large deletion demonstrated in
fucosidosis. It is interesting that this patient has a relatively mild clinical course despite the absence of the mRNA. This
case also indicates the difficulty in determining the phenotype from the genotype in fucosidosis.

Summary The properties of single cortical neurons responding to electrical stimulation of the tooth-pulp and to intrapulpal application of bradykinin were studied in the cat. The activities of tooth-pulp driven neurons (TPNs) were recorded from the middle and anterior parts of the coronal gyrus of the cerebral cortex. Bradykinin-sensitive tooth-pulp driven neurons (BK-TPNs) were located in layer IV of area 3b of the anterior part of the coronal gyrus. These neurons had a large cutaneous oro-facial receptive field and received a nociceptive input from the facial skin as well as from the tooth-pulp. The BK-TPNs had a higher threshold and longer latency to electrical stimulation than TPNs insensitive to bradykinin (non BK-TPNs). These findings suggest that BK-TPNs in this cortical area may be involved in sensory processing of noxious information from trigeminal regions. 相似文献

Selective potentiation of extracellular Ca2+-dependent contraction by neuropeptide Y in rabbit mesenteric arteries 总被引:2,自引:0,他引:2
1. Neuropeptide Y (NPY) potentiated the contractile responses induced by electrical transmural stimulation, noradrenaline and KCl in the rabbit mesenteric artery. 2. In preparations treated with noradrenaline or KCl in Ca2+ free medium, NPY also potentiated the contractile response induced by resupplementation of Ca2+. 3. 3H-efflux from the arteries preincubated with [3H]-noradrenaline was not affected by NPY. 4. These results suggest that NPY selectively acts on the postsynaptic membrane and potentiates the contractions mediated through receptor-operated and voltage-dependent Ca channels. 相似文献

Pathological fractures caused by metastatic malignant disease have been the subject of increasing interest in recent years. This article describes our experience with the treatment of metastatic bone disease of the upper extremity and our attempt to clarify the indications for different surgical procedures. Of 53 patients with metastatic lesions to the upper extremity, 20 who had been surgically treated were analyzed retrospectively. These comprised 13 men and 7 women with a mean patient age of 62 years. The most common primary tumors to metastasize were lung and liver, with the humerus involved in 12 cases and the scapula and forearm in 4 cases each. Four patients with scapula and forearm involvement underwent tumor resection due to uncontrollable tumor size, while 3 were successfully treated by selective arterial embolization. Three metastases to the humeral head were reconstructed with endoprosthesis, but functional restriction was noted. Five cases with metastases to the humeral shaft were treated with tumor curettage, internal fixation using intramedullary nailing, adjuvant cryosurgery, and cementing. This achieved good results for pain relief and functional restoration with minimal complications. Two metastases to the humeral condyle were unable to be stabilized with plate and locking screws. Metastatic lesions to the scapula and forearm are commonly treated nonsurgically, but some patients with uncontrollable tumor mass require surgical resection. Endoprosthetic replacement is recommended if the lesion involves the humeral head or condyle. Most patients with the humeral shaft lesion are likely to benefit from tumor curettage, intramedullary nailing with locking screw, and cementing. 相似文献
