OBJECTIVE: Complex evaluation of the functional system "mother-placenta-fetus" in intrauterine growth restriction (IUGR) for the prognosis of risk of perinatal complications and optimization of choice of method of delivery. METHODS: We created an objective scale for the evaluation of pregnancies complicated by IUGR using 19 fetometric, dopplerometric and pulsometric parameters. We prospectively followed 130 fetuses classified into three risk groups determined by our prognostic scale with a control group of 25. Operative method of delivery was recommended for medium and high risk groups. We examined newborns with the help of neurosonography and compared them to 139 retrospective newborns classified into three groups according to severity of IUGR with a control group of 25. RESULTS: C-sections were higher by 27 and 12% in the prospective medium and high risk groups. Ventriculomegaly, brain edema, hemorrhages and pathological vascular pulsation decreased by 9, 27, 12 and 21%. Perinatal mortality decreased by 4%. CONCLUSIONS: The developed IUGR prognostic scale optimized the choice of method of delivery and led to decreased rates of neurological morbidity and mortality in newborns with IUGR. 相似文献

BACKGROUND: Patients with primary hypogammaglobulinemia have been reported to have encephalopathy, but progressive multifocal leukoencephalopathy (PML) due to JC virus reactivation is a rare cause. OBJECTIVE: To provide the clinical details and case discussion of a patient diagnosed as having common variable immunodeficiency (CVID) who has progressive neurodegenerative symptoms and was found to have PML and an abnormal CD8+ T-cell subset distribution. METHODS: A detailed case report providing the patient's immunodeficiency history, diagnostic evaluation, and medical management and a review of related literature. RESULTS: Before his neurodegenerative illness, the patient was found to have hypogammaglobulinemia, poor specific antibody responses, low circulating B-cell levels, and abnormal delayed-type hypersensitivity responses; there was no Bruton tyrosine kinase (BTK) mutation. The PML was diagnosed using brain biopsy and was confirmed using a DNA probe specific for JC virus. Peripheral blood flow cytometry at the time of PML diagnosis revealed an accumulation of naive CD8+ T cells (CD3+CD8+CD45RA+) and a deficiency of memory CD8+ T-cell subsets (CD3+CD8+CD45RA- or CD3+CD8+CD45RO+). Despite aggressive treatment with interleukin 2, interferon-gamma, and intravenous cidofovir, the patient died. CONCLUSIONS: JC virus infection should be considered in the differential diagnosis of the patient with CVID and signs and symptoms of encephalopathy. The role of this patient's abnormal CD8' T-cell subset distribution in the development or control of this rare infection is worthy of consideration and has encouraged us to enumerate naive and memory CD4+ and CD8+ T-cell subsets in patients diagnosed as having CVID, even in the absence of neurodegenerative symptoms. 相似文献

A chest wall abscess is a very rare presentation of extranodal Hodgkin's lymphoma (HL); only one case has been reported to date. Here, we describe a case of a 38-yr-old man with HL whose initial presentation was a chest wall abscess. The diagnosis of HL was suggested by cytological examination of the purulent discharge and was confirmed subsequently by excisional biopsy of cervical lymph node. 相似文献

Objective: To assess and compare the effectiveness and safety of single IV polus dose of carbetocin, versus IV oxytocin infusion in the prevention of PPH in obese nulliparous women undergoing emergency Cesarean Delivery.Methods: A double-blinded randomized-controlled trial was conducted on 180 pregnant women with BMI >30. Women were randomized to receive either oxytocin or carbetocin during C.S. The primary outcome measure was major primary PPH >1000?ml within 24?h of delivery as per the definition of PPH by the World Health Organization Secondary outcome measures were hemoglobin and hematocrit changes pre- and post-delivery, use of further ecobolics, uterine tone 2 and 12-h postpartum and adverse effects.Results: A significant difference in the amount of estimated blood loss or the incidence of primary postpartum haemorrhage (>1000?ml) in both groups. Haemoglobin levels before and 24-h postpartum was similar. None from the carbetocin group versus 71.5% in oxytocin group needed additional utrotonics (p?<?0.01). The uterine contractility was better in the carbetocin group at 2, and 12-h postpartum (p?<?0.05).Conclusions: A single 100-µg IV carbetocin is more effective than IV oxytocin infusion for maintaining adequate uterine tone and preventing postpartum bleeding in obese nulliparous women undergoing emergency cesarean delivery, both has similar safety profile and minor hemodynamic effect. 相似文献

Distribution of avian influenza H5N1 viral RNA in tissues of AI-vaccinated and unvaccinated contact chickens after experimental infection 总被引:1,自引:0,他引:1

Avian influenza due to highly pathogenic avian influenza (HPAIV) H5N1 virus is not a food-borne illness but a serious panzootic
disease with the potential to be pandemic. In this study, broiler chickens were vaccinated with commercial H5N1 or H5N2 inactivated
vaccines prior to being challenged with an HPAIV H5N1 (clade 2.2.1 classic) virus. Challenged and non-challenged vaccinated
chickens were kept together, and unvaccinated chickens served as contact groups. Post-challenge samples from skin and edible
internal organs were collected from dead and sacrificed (after a 14-day observation period) birds and tested using qRT-PCR
for virus detection and quantification. H5N1 vaccine protected chickens against morbidity, mortality and transmission. Virus
RNA was not detected in the meat or edible organs of chickens vaccinated with H5N1 vaccine. Conversely, H5N2 vaccine did not
confer clinical protection, and a significant virus load was detected in the meat and internal organs. Phylogenetic analysis
showed that the H5N1 virus vaccine and challenge virus strains are closely related. The results of the present study strongly
suggest a need for proper selection of vaccines and their routine evaluation against newly emergent field viruses. These actions
will help to reduce human exposure to HPAIV H5N1 virus from both infected live birds and slaughtered poultry. In addition,
rigorous preventive measures should be put in place in order to minimize the public-health risks of avian influenza at the
human-animal interface. 相似文献

We studied the effects of HLA disparity, immunosuppressive regimen used, and the type of kidney allograft on production of anti-HLA antibodies after transplant and the occurrence of rejection episodes. Five living-unrelated donors and 4 living-related donors kidney recipients received quadruple therapy (including sirolimus and mycophenolate mofetil). Fifteen living-unrelated donors and 19 living-related donors received triple therapy (excluding sirolimus). A single bolus of 4 to 6 mg/kg rabbit anti-human T-lymphocyte immune serum was included with both regimens. Recipients were studied over a 3-year period. Human leukocyte antigen profiles were determined by DNA (SSP) typing, and anti-HLA class-I antibodies were determined by the complement-dependent microcytotoxicity assay and an enzyme-linked immunosorbent assay. The degree of HLA disparity did not appear to affect anti-HLA antibody production or the occurrences of rejection episodes. None of the patients who received quadruple therapy developed anti-HLA class-I antibodies. Two living-unrelated donors and 2 living-related donors recipients who received triple therapy developed anti-HLA class-I antibodies. One of the 2 living-unrelated donors antibody-positive patients rejected the kidney and returned to dialysis, and the other patient has normal graft function 3 years after the transplant. The 2 living-related donors patients with normal graft function were antibody-positive 1 year after the transplant but were antibody-negative at 2 and 3 years after transplant. Sirolimus appeared to inhibit production of antibodies after transplant. Moreover, use of present day immunosuppressive agents diminishes the role of HLA matching in relation to the occurrence of rejection episodes. 相似文献
