Early platelet consumption in pre-eclampsia 总被引:2,自引:0,他引:2
One hundred and thirty-one women with chronic hypertension were studied serially during pregnancy to determine the sequence of events in the development of superimposed pre-eclampsia and to discover the time of onset. Twenty-seven women developed a sustained rise in plasma urate concentrations, which began at about 28 weeks' gestation and which is characteristic of pre-eclampsia. The mean platelet count was already significantly reduced and continued to fall until delivery, which was on average at 36 weeks' gestation. A comparable but smaller decrease in platelet count was seen in 55 women who had borderline but consistent increases in plasma urate concentrations. In 49 women whose plasma urate concentrations remained steady the platelet count did not change significantly before delivery. The reduced platelet count in women who develop pre-eclampsia suggests that increased platelet consumption is an early feature of the disorder. 相似文献

The successful removal of a large inferior vena caval isthmus of nephroblastoma is reported. Control of the inferior vena cava was obtained in the pericardial sac through a median sternotomy incision. Complete removal of nephroblastoma can be increased by being well prepared to approach surgically all organs and structures involved. 相似文献

A case of extensive condyloma acuminatum of the entire male urethra was successfully managed with 5-fluorouracil intraurethral instillations. Review of the literature disclosed 9 previously reported cases in which the entire male urethra was involved. The common presentations and different modalities of treatment are reviewed. 相似文献

PURPOSE: Studies suggest that nerve growth factor (NGF) contributes to bladder overactivity stemming from bladder inflammation. Studies were performed to determine the NGF dependence of cyclophosphamide (CYP) induced changes in bladder function using the recombinant NGF sequestering protein REN1820. MATERIALS AND METHODS: Urodynamic testing and behavioral observations were made in female rats treated with CYP (4 or 48 hours) and REN1820 or vehicle. RESULTS: Rats examined 4 or 48 hours after CYP treatment plus REN1820 showed significantly fewer nonvoiding contractions with smaller amplitude (p =0.01). Rats examined 48 hours after CYP treatment plus REN1820 showed decreased voiding frequency (p =0.01). No changes in filling, threshold or micturition pressure were observed with REN1820 treatment. Rats treated with CYP plus REN1820 showed greater mobility and normal resting postures compared with rats treated with CYP plus vehicle. CONCLUSIONS: These studies demonstrate that the use of the NGF sequestering protein REN1820 in rats with CYP induced cystitis decreases bladder overactivity. This is characterized by 1) a decrease in the number and amplitude of nonvoiding contractions and 2) decreased voiding frequency. Rats treated with REN1820 showed greater mobility and normal resting postures, which may reflect improved overall health or well-being. REN1820 may prove to be a novel therapeutic in individuals with the chronic inflammatory bladder syndrome interstitial cystitis. 相似文献

Glucose in bronchial aspirates increases the risk of respiratory MRSA in intubated patients 总被引:6,自引:0,他引:6
BACKGROUND: The risk of nosocomial infection is increased in critically ill patients by stress hyperglycaemia. Glucose is not normally detectable in airway secretions but appears as blood glucose levels exceed 6.7-9.7 mmol/l. We hypothesise that the presence of glucose in airway secretions in these patients predisposes to respiratory infection. METHODS: An association between glucose in bronchial aspirates and nosocomial respiratory infection was examined in 98 critically ill patients. Patients were included if they were expected to require ventilation for more than 48 hours. Bronchial aspirates were analysed for glucose and sent twice weekly for microbiological analysis and whenever an infection was suspected. RESULTS: Glucose was detected in bronchial aspirates of 58 of the 98 patients. These patients were more likely to have pathogenic bacteria than patients without glucose detected in bronchial aspirates (relative risk 2.4 (95% CI 1.5 to 3.8)). Patients with glucose were much more likely to have methicillin resistant Staphylococcus aureus (MRSA) than those without glucose in bronchial aspirates (relative risk 2.1 (95% CI 1.2 to 3.8)). Patients who became colonised or infected with MRSA had more infiltrates on their chest radiograph (p<0.001), an increased C reactive protein level (p<0.05), and a longer stay in the intensive care unit (p<0.01). Length of stay did not determine which patients acquired MRSA. CONCLUSION: The results imply a relationship between the presence of glucose in the airway and a risk of colonisation or infection with pathogenic bacteria including MRSA. 相似文献
