We report on a 3 year old girl with acute promyelocytic leukemia (APL) with cerebral infarction due to disseminated intravascular coagulation (DIC) at initial presentation. She was hospitalized because of unconsciousness and petechiae on the chest wall and extremities. Cerebral ischemia and infarction were found on computed tomography scan and magnetic resonance imaging. Peripheral bood content was hemoglobin 7.3 g/dL, white blood cells 1.0 × 103cells/μL (31% blasts) and platelet count was 12 × 103cells/μL. Fragmented erythrocytes were frequently observed on May-Giemsa stained blood smears. Bone marrow aspirates showed normal cellularity, with 60.4% blasts, containing faggot cells. The blasts were positive for peroxidase. Therapy was begun; however, the patient died 1 week after admission. 相似文献

Summary. Background and objectives: Genes encoding protein C anticoagulant pathways are candidates for atherothrombotic and other aging‐related disorders. Methods: Using a tagSNP approach, and data from the Cardiovascular Health Study (CHS), we assessed associations of common polymorphisms of PROC, PROS1 and PROCR with: (i) plasma protein C, soluble protein C endothelial receptor (sEPCR) and protein S levels measured in a subsample of 336 participants at study entry; and (ii) risk of incident clinical outcomes [coronary heart disease (CHD), stroke, and mortality] in 4547 participants during follow‐up. Secondarily, we explored associations between plasma protein C, protein S and sEPCR levels and other candidate genes involved in thrombosis, inflammation, and aging. Results: The PROCR Ser219Gly polymorphism (rs867186) was strongly associated with higher sEPCR levels, explaining 75% of the phenotypic variation. The PROCR Ser219Gly variant was also associated with higher levels of circulating protein C antigen. An IL10 polymorphism was associated with higher free protein S levels. The minor alleles of PROC rs2069901 and PROS1 rs4857343 were weakly associated with lower protein C and free protein S levels, respectively. There was no association between PROCR Ser219Gly and risk of CHD, stroke, or mortality. The minor allele of another common PROCR tagSNP, rs2069948, was associated with lymphoid PROCR mRNA expression and with increased risk of incident stroke and all‐cause mortality, and decreased healthy survival during follow‐up. Conclusions: A common PROCR variant may be associated with decreased healthy survival in older adults. Additional studies are warranted to establish the role of PROCR variants in ischemic and aging‐related disorders. 相似文献

Summary. We studied the effect of intravenous administration of 13,14-dihydro-15-keto-prostaglandin (PG) F27alpha; on airway responsiveness to histamine and airway wall thickening in guinea-pigs. Guinea-pigs were killed and the lungs were fixed in formalin. Slides from paraffin-embedded sections of the lungs were stained and the airways that were cut in transverse section were measured by tracing enlarged images using a digitizer. Moreover, airway resistance (Raw) was determined by a pulmonary mechanics analyser and we calculated two indices, an index of airway wall thickening and the one of airway hyperresponsiveness to histamine, from changes of baseline-Raw and peak-Raw following intravenous administration of histamine before and after the intravenous administration of 13,14-dihydro-l5-keto-PGF2n . Intravenous administration of 10/μg/kg 13,14-dihydro-15-keto-PGF2α for 1 h did not induce an increase of the relative thickness of the airway wall by the histological examination. In analysis of airway function, intravenous administration of 10μg/kg 13,14-dihydro-15-keto-PGF2α for 1 h induced airway hyperresponsiveness to histamine without airway wall thickening. Thromboxane A2 (TXA2 ) receptor antagonists ONO-NT-126 and ONO-8809 inhibited the 13,14-dihydro-15-keto-PGF2α -induced airway hyperresponsiveness to histamine, suggesting that the effect of 13,14-dihydro-15-keto-PGF2α on bronchial hyperresponsiveness is likely to be mediated through TXA2 . 相似文献

A case is reported of congenital malignant melanoma that occurred in the absence of maternal melanoma or a congenital giant naevus. The patient had the melanoma on the left thigh excised 54 days after birth, but later died at the age of 18 months with multiple metastases. 相似文献

Background. Systemic lupus erythematosus (SLE) is designated by the Japanese government as one of the intractable diseases and all patients, who suffer from these diseases, are registered to get financial aid for treatment. Using newly registered SLE patients, a case-control study was conducted to evaluate potential risk factors. Methods. Two-hundred and eighty-two women SLE patients, newly registered to receive financial aid for treatment, and 292 randomly selected health examination participants at public health centers (controls) were surveyed from April 1988 through March 1990. By means of a self-administered questionnaire, data concerning demographic variables, smoking and drinking habits, past medical and reproductive history, and family history were collected. Results. Based on unconditional logistic regression analysis, the risk of SLE was significantly increased for current smokers (age-adjusted odds ratio (OR) = 2.31, 95% confidence interval (CI) (1.34–3.97). Alcohol and milk intake were inversely associated with risk. Family histories of asthma and collagen diseases, including SLE, were associated with significantly elevated risk of SLE (OR = 2.07, 95% ci 1.14–3.77; OR = 5.20, 95% CI 1.08–24.95, respectively). Regarding reproductive function, women with menarche at age 15 or later had significantly higher risk than those, who started menstruating before age 12 (OR = 3.82, 95% CI 1.66–8.81 for menarche at > 15 years and OR = 2.90, 95% a 1.14–7.39 for menarche at 16y). Conclusions. Our study suggests several risk factors, including smoking, family history, and reproductive history that may increase the risk of SLE. 相似文献
