BACKGROUND: Mirror syndrome is associated with both nonimmune and immune hydrops fetalis. The clinical manifestations are quite varied, and the pathophysiology is poorly understood. We describe a case of mirror syndrome associated with afetus that had a rapidly growing sacrococcygeal teratoma (SCT) without overt hydrops. CASE: At 30 weeks' gestational age a fetus with SCT began to show early sonographic evidence of right heart failure, placentomegaly and polyhydramnios without overt fetal hydrops. Shortly after these findings were noted, the mother began to develop hypertension, epigastric pain, proteinuria and thrombocytopenia. These findings were all reversed after delivery of the fetus. Subsequent surgery on the infant was successful. CONCLUSION: Mirror syndrome has been linked with SCT and is usually associated with severe fetal hydropic changes. In our case the development of mirror syndrome preceded the manifestations of overt hydrops. Identification of early signs of fetal compromise or hydrops may help to predict patients who will develop mirror syndrome and improve outcomes with earlier intervention. 相似文献

Ondansetron and tropisetron in the control of nausea and vomiting in children receiving combined cancer chemotherapy 总被引:1,自引:0,他引:1

Ondansetron (Zofron, Glaxo) and tropisetron (Navoban, Sandoz) are selective serotonin (5HT ) 3 antagonists that have proven very effective in the prevention of vomiting and nausea in adults and children receiving cancer chemotherapy. This study compared the efficacy of the two agents in the prevention of vomiting and nausea in children receiving chemotherapy for solid tumors and blood malignancies. A total of 23 children were studied in 205 chemotherapeutic cycles (116 oneday regimens and 89 multiple-day regimens). In 102 chemotherapeutic cycles the children received ondansetron as an antiemetic agent in a dose of 5 mg/m 2 30 min before chemotherapy was given and then 4 mg/m 2 every 8 h IV (group A) and in 103 cycles they received tropisetron in one dose of 0.2 mg/kg 24 h 1 IV (max dose 5 mg) 30 min before cytotoxic drugs administration every day they received chemotherapy (group B). The response was defined as complete in the absence of nausea and vomiting per 24 h of chemotherapy, as partial given the presence of 1-4 events of vomiting and/or nausea less than 5 h per 24 h, and as failure if there were more than 4 events of vomiting and/or nausea for more than 5 h per 24 h of chemotherapy. The response of the two groups was studied independently and depending on the degree of emetogenicity of the chemotherapeutic agents, which were divided into mildly, moderately, and highly emetogenic. The comparison of the two groups not taking into consideration the emetogenicity of the chemotherapeutic agents showed that ondansetron was more effective in 1-day regimens ( P = . 023 ), whereas the two agents were equally effective in multiple-day regimens ( P = . 2 ). The statistical analysis depending on the emetogenicity of the chemotherapeutic agents showed increased efficacy of ondansetron in mild ( P = . 017 ) and moderately emetogenic chemotherapeutic agents, whereas there was no difference in the highly emetogenic drug group. Ondansetron is found to be more effective than tropisetron in controlling acute nausea and vomiting in children receiving mild and moderately emetogenic chemotherapeutic drugs, although there is no difference in the efficacy of both antiemetic agents when highly emetogenic drugs are administered. 相似文献

Inflammatory chemokine expression in the peripheral blood of neonates with perinatal asphyxia and perinatal or nosocomial infections 总被引:3,自引:0,他引:3

AIM: The inflammatory response induced by perinatal infections and asphyxia is considered to participate in neonatal brain damage. Inflammatory responses are characterized by the expression of chemokines. Although chemokine levels have been investigated in healthy newborns, their role during neonatal pathological conditions has not been studied. The aim of our study was to examine chemokine serum levels in asphyxiated and infected neonates. METHODS: Peripheral blood samples were obtained from perinatally asphyxiated and infected neonates during the first days of life and from neonates who developed nosocomial infections. Serum levels of interleukin-8 (IL-8), interferon-gamma-inducible protein-10 (IP-10), monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1alpha (MIP-1alpha), and regulated upon activation, normal T cells expressed and secreted (RANTES) were determined. RESULTS: In perinatally asphyxiated neonates, IL-8 levels were significantly elevated on the 1st day of life. In perinatally infected neonates, IL-8 and IP-10 levels were significantly increased on the 1st day of life, while RANTES levels were significantly lower and remained so until the 4th day. In nosocomially infected neonates, IL-8, IP-10 and MIP-1alpha levels were significantly increased on diagnosis of infection. CONCLUSION: The neonatal immune system is able to produce chemokines for the induction of an inflammatory response during perinatal asphyxia and perinatal or nosocomial infections. Blockade of inflammatory chemokines could possibly contribute to the prevention of brain damage. 相似文献

BACKGROUND: The prevalence of thrombophilic traits, which might further enhance the risk of thrombotic complications in children treated for cancer, varies significantly among different populations. OBJECTIVE: To evaluate the prevalence of common thrombophilic traits of the East Mediterranean Region, among native Cretan children treated for malignancy. METHODS: Blood samples were consecutively collected from 31 native Cretan children treated for acute lymphoblastic leukaemia (n = 19) or other malignancies (n = 12) over 3 years. A molecular diagnosis based on the presence of Factor V Leiden (FVL), as well as on PT G20210A and MTHFR C677T mutation (in 14 patients) using PCR was applied. Patients who had central venous catheters (n = 29) were treated with an intensified thromboprophylaxis protocol that had been previously established in our institution. RESULTS: The prevalence of the FVL mutation was 19.4% (95% CI = 5-32). The allele frequency is estimated at 11.3% (95% CI: 3.5-19.1) which is higher than that reported for the population of the mainland of Greece. The prevalence of the PT G20210A and MTHFR C677T mutation was 14.3 and 71.4%, respectively (corresponding allele frequencies 7.1 and 50%, respectively). Only one patient developed thrombosis, having although no thrombophilic trait. CONCLUSIONS: Thrombophilic traits were relatively common in this group of native Cretan children treated for malignancy. Thromboprophylaxis should be considered in Cretan children in the presence of known acquired risk factors for thrombosis, but a larger prospective to study is first needed. 相似文献

We describe the case of an 8-year-old girl without neurofibromatosis, who presented with total loss of vision on the left eye, due to a chiasmatic mass with imaging characteristics of glioma, accompanied by a second asymptomatic mass in the middle cranial fossa, along the intracranial route of the right trigeminal nerve. The patient received a total of 10 weekly injections of vincristine and four injections of carboplatin every 3 weeks and achieved a very good partial response (97% volume reduction) after the nineth week of therapy with acceptable toxicity. Given the natural history of opticochiasmatic gliomas, we cannot rule out the possibility of a spontaneous regression. However, we believe the quick response accompanied by visual improvement was most likely due to chemotherapy. A trial of vincristine and carboplatin may be worthwhile in children with symptomatic chiasmatic gliomas, irrespective of their age. 相似文献

Capnocytophaga species are inhabitants of the normal mouth flora. We describe the case of a 6-year-old-girl with leukemia and poor oral hygiene who developed bacteremia caused by Capnocytophaga gingivalis. The organism was detected only on quantitative blood cultures. 相似文献
