It is not exactly known the risks from infection with pandemic influenza (H1N1) 2009 in children with leukemia. Here the authors present their experience in 5 children with leukemia. Pandemic influenza (H1N1) 2009 was detected in 5 patients (F/M: 3/2) at their institution. The ages of these patients were between 2 and 16 years. Four had acute lymphoblastic leukemia (ALL) and 1 acute myeloblastic leukemia (AML). Three of the ALL patients had the diagnosis of pandemic influenza (H1N1) 2009 at the same time as they were diagnosed with ALL. The remaining 2 patients were receiving intensive chemotherapy. All patients had fever, rhinorrhea, and cough. Although bronchopneumonia was seen in 3 patients, only 1 revealed respiratory distress. Stomach ache and diarrhea was seen in the patient who had no pneumonia. All treated as inpatients, but none of them required hospitalization in intensive care unit. One to 3 days after the symptoms of influenza appeared, oseltamivir (Tamiflu) was given to all patients in combination with broad-spectrum antibiotics. Fever declined to normal ranges in 1 to 3 days after treatment was started. The patients received oseltamivir for 5 to 7 days. Cell culture tests were found to be positive for influenza A and polymerase chain reaction (PCR) revealed H1N1 for all 5 patients. Although this is a very small case series, pandemic influenza (H1N1) 2009 did not seem to be very dangerous for children with leukemia if the oseltamivir treatment was given early when symptoms of influenza appeared. 相似文献

Congenital neutropenia syndromes 总被引:1,自引:0,他引:1

Congenital neutropenia syndromes comprise a heterogeneous group of inherited disorders. Hereditary conditions associated with low neutrophil counts are persistent and need to be differentiated from neutropenia secondary to autoimmune processes or other pathologic conditions, such as myelodysplasia or leukemia. Clinically, congenital neutropenia is characterized by recurrent bacterial infections. Recently, several novel genetic defects were described in patients with congenital neutropenia, shedding light on the pathophysiology of these rare diseases. 相似文献

Background:Excess carbohydrate intake during hypoglycemia can lead to rebound hyperglycemia (RH). We investigated associations between RH and use of real-time continuous glucose monitoring (rtCGM) and an rtCGM system’s predictive alert.Methods:RH events were series of sensor glucose values (SGVs) >180 mg/dL starting within two hours of an antecedent SGV <70 mg/dL. Events were characterized by their frequency, duration (consecutive SGVs >180 mg/dL × five minutes), and severity (area under the glucose concentration-time curve). To assess the impact of rtCGM, data gathered during the four-week baseline phase (without rtCGM) and four-week follow-up phase (with rtCGM) from 75 participants in the HypoDE clinical trial () of hypoglycemia-unaware individuals were compared. To assess the impact of predictive alerts, we identified a convenience sample of 24 518 users of an rtCGM system without predictive alerts who transitioned to a system whose predictive alert signals an SGV ≤55 mg/dL within 20 minutes (Dexcom G5 and G6, respectively). RH events from periods of blinded versus unblinded rtCGM wear and from periods of G5 and G6 wear were compared with paired t tests.Results:Compared to RH events in the HypoDE baseline phase, the mean frequency, duration, and severity of events fell by 14%, 12%, and 23%, respectively, in the follow-up phase (all P < .05). Compared to RH events during G5 use, the mean frequency, duration, and severity of events fell by 7%, 8%, and 13%, respectively, during G6 use (all P < .001).Conclusions:Rebound hypreglycemia can be objectively quantified and mitigated with rtCGM and rtCGM-based predictive alerts.

Increasing evidence suggests multilineage cytopenias (also known as Evans syndrome) may be caused by inborn errors of immunity (IEI) with immune dysregulation. We studied a patient with autoimmune haemolytic anaemia and immune thrombocytopenia and identified a germline mutation in SASH3 (c.862C>T;p.Arg288Ter), indicating a recently identified IEI. Immunohistochemistry performed after clinically indicated splenectomy revealed severe hypoplasia/absence of germinal centres. The autoimmune phenotype was associated with an increased CD21lowT-bet+CD11c+ subset along with decreased regulatory T cells, impaired T-cell proliferation and T-cell exhaustion. The younger brother carries the same SASH3 mutation and shares immunophenotypic features but is currently clinical asymptomatic, indicating heterogeneity of SASH3 deficiency. 相似文献

Vertical root fractures (VRFs) can start at any level of the root and progress longitudinally to the coronal attachment. This study aimed to investigate the effects of different exposure parameters used when obtaining CBCT scans in detecting simulated VRFs. Hence, 80 intact human mandibular single-rooted pre-molar teeth without root fractures were included in the study. No statistically significant difference was found between the filters in terms of VRF detection in the group with the roots with only root canal filling (Groups 1 and 5); however, 100 voxels were found to be more successful in terms of VRF detection than other voxel sizes. Results of this study suggest that using lower voxel sizes leads to an accurate diagnosis of vertical root fracture, in addition, our results revealed that using AR filters did not improve the diagnostic accuracy in detecting VRFs. 相似文献
