OBJECTIVE: To compare the incidence and detect the volume of fetomaternal hemorrhage (FMH) during first-trimester abortion with the Kleihauer-Betke test (KBT) and rise in maternal serum alpha-fetoprotein (AFP). STUDY DESIGN: Blood samples were drawn immediately before and after first-trimester termination of pregnancy in 48 women. AFP was estimated using an enzyme-linked immunosorbent assay technique. Fetal cells were counted using the acid elution technique described by Kleihauer. Volume of FMH with both techniques was calculated using standard formulae. Significant FMH was reported when there was a > 40% rise in AFP or > 0.25 mL bleed detected by KBT. RESULTS: Of the 48 cases studied, 18 (37.5%) showed no indication of FMH by either AFP or KBT. In 30 (62.5%) cases there was evidence of FMH; in 7 (14.6%) this was shown by both AFP and KBT. Another 10 (21%) showed significant changes in AFP concentration only, and 13 (27%) showed abnormal KBT results with stable AFP levels. The incidence of detectable FMH after first-trimester abortion in this series was 35% when assessed by AFP and 42% when assessed by KBT (P > .05). The mean volume of FMH detected by KBT was 0.5+/-0.05 mL and by AFP was 0.01+/-0.02 mL. CONCLUSION: This study showed that AFP and KBT are equally sensitive methods of detecting the incidence of FMH in first-trimester abortion, but concordance between the 2 tests is poor. The volume of FMH detected by KBT and FMH is also significantly different. 相似文献

OBJECTIVE: To evaluate protien using enteropathy by Tc-99m dextran scintigraphy. METHODS: Methods for detecting protein loss from the intestine revolve around fecal nitrogen excretion, the clearance of alpha-1 antitrypsin in stools and by endoscopic biopsy. RESULT: The diagnosis of protein-losing enteropathy (PLE) can also be established by a scintigraphic method that is noninvasive, simple and requires no patient preparation or motivation. This diagnostic modality can also delineate the site of protein loss, thereby offering a targeted approach, and if need be, surgery. Radiolabelling of a non-protein, noncolloidal, nonparticulate and biofriendly molecule like dextran with Technetium-99m for imaging enteric protein loss was utilized in imaging eight children with PLE. CONCLUSION: The results were encouraging. The authors advocate the use of this diagnostic tool in identifying patients with PLE, particularly in the pediatric age group. 相似文献

Conventional Giemsa stained peripheral blood smear examination for demonstration of malarial parasites remains the gold standard for diagnosis of malaria in developing endemic countries. However this technique is time consuming, requires training and may give poor results in cases with low parasitaemia. To overcome these problems and improve diagnostic accuracy two newer tests have been studied and compared with standard Giemsa staining. These are the wet mount fluorescence microscopy of Acridine Orange stained thin blood films (A.O.) and the Quantitative Buffy Coat technique (Q.B.C) for diagnosis of malaria. A.O. staining was found to be 97.5% sensitive and 100% specific for detection of all stages and species of malarial parasite. The Q.B.C assay was found to be 100% sensitive and 97.5% specific for diagnosis of malaria. A.O. staining was very fast and the species identification was easy once the staining was optimised. The Q.B.C. test required considerable amount of practice, costly equipment, however it was fast and in our study was found to be highly sensitive. 相似文献

Complex formation of rofecoxib and beta-cyclodextrin in aqueous solution and in solid state and the possibility of improving the solubility and dissolution rate of rofecoxib via complexation with cyclodextrin were investigated. Phase solubility studies indicated the formation of an 1:1 complex in solution and the value of apparent stability constant was 769 M(-1). Solid inclusion complexes of rofecoxib and cyclodextrin were prepared by the kneading method in different molar ratios. Differential scanning calorimetry studies indicated the formation of solid inclusion complexes of rofecoxib and cyclodextrin at different molar ratios and the solid complexes exhibited a higher rate of dissolution than the physical mixture and the pure drug. 相似文献

The prevalence of anaemia in 504 adolescent girls (10-18 yrs) representing 24 subcentre villages of Daurala block of Meerut was 34.5%. The prevalence of mild, moderate and severe anaemia among adolescent girls was 19.0%, 14.0% and 1.4% respectively. Majority (55.2%) were having mild anaemia and only 4.0% had severe anaemia. Anaemia was found to be significantly associated with educational status (P < 0.05), birth order (P < 0.05), awareness regarding anaemia (P < 0.05) and marital & obstetric status (P < 0.05) with no association with age, anthropometry and menarcheal age (P > 0.05). 相似文献

Altered gallbladder contractility after extracorporeal shock-wave cholecystolithotripsy 总被引:1,自引:0,他引:1
Change in gallbladder contractility after biliary extracorporeal shock-wave lithotripsy (ESWL) may significantly influence the clearance of fragments after successful gallstone fragmentation. We assessed changes in gallbladder contractility in response to an oral fatty meal in 50 patients 1 month after biliary ESWL (all fragments were smaller than 3 mm) and also in a separate group of 10 patients 3 months after complete clearance of fragments. The prevalence of persistent lumen-obliterating contraction of the gallbladder after biliary ESWL also was analyzed in 325 patients. Gallbladder contractility remained unchanged in 30, increased in nine, and decreased in 11 of the 50 patients. The average reduction in the fasting gallbladder volume after lithotripsy was 28% (p less than .001). Gallbladder contractility remained unchanged 3 months after complete clearance of fragments in six of 10 patients studied separately. A decrease (n = 2) or increase (n = 2) in contractility was seen in the remaining patients. No significant difference occurred in the average ejection fraction of the gallbladder before lithotripsy and after complete clearance of the fragments. Thirty-four of the 325 patients who have so far undergone biliary ESWL had a completely contracted gallbladder with no lumen visible on sonography. The gallbladder returned to a relaxed state in half of these patients within 1-9 months. Thus, biliary ESWL did not significantly alter gallbladder contractility in 60% of patients. A significant reduction in the volume of the fasting gallbladder occurred after lithotripsy. Successful clearance of fragments did not improve the contractility of stonebearing gallbladders in the majority of patients. 相似文献

One hundred thirty-six patients completed extracorporeal biliary lithotripsy (EBL) for symptomatic cholecystolithiasis. Sonographic evidence of complete clearance of all stone fragments was the only criterion for treatment success, which occurred in 32 of the 71 patients (45%) followed up for 24 weeks and in 36 of the 59 patients (61%) followed up for 52 weeks. The authors' protocol varied from protocols of other researchers primarily in that no adjuvant chemolitholysis was used. However, the number of treatment sessions and total number of shock waves (a maximum of 4,000 shock waves per treatment session, 12,000 shock waves in a patient demonstrating no significant fragmentation, and 20,000 shock waves in a patient whose stones responded well to fragmentation) was higher than those in other reports. The results of treatment and complication rates in this study are comparable with those at centers using both shock-wave lithotripsy and chemotherapy. The authors conclude that EBL is developing into an important alternative to surgery, which was obviated in all patients with complete clearance of fragments from the gallbladder. 相似文献
