1.Fetal fibronectin (Quick Check fFN test) versus placental alpha microglobulin-1 (AmniSure test) for detection of premature rupture of fetal membranes.
Abdelazim IA;Abdelrazak KM;Al-Kadi M;Yehia AH;Abdulkareem AF Arch Gynecol Obstet. 2014 Sep;290(3):457-64. doi: 10.1007/s00404-014-3225-5. Epub 2014 Apr 9.
OBJECTIVES: ;To compare accuracy of fetal fibronectin (fFN) versus placental alpha microglobulin-1 for detection of premature rupture of fetal membranes (PROM).;METHODS: ;Two hundred and twenty pregnant women >34 and <37 weeks were included in this comparative prospective study and divided into two groups according to presence or absence of PROM. The diagnosis of PROM was based on patient's history of sudden gush of water, pooling of amniotic fluid, positive ferning, positive nitrazine test, confirmed by visualization of fluid passing from the cervical canal and amniotic fluid index ≤5 cm measured by trans-abdominal ultrasound. Patients included in this study were examined by sterile speculum for visualization of membranes and for collection of samples (swabs) from posterior vaginal fornix.;RESULTS: ;Sensitivity and specificity of AmniSure test to diagnose PROM were 97.3 and 98.2 %, respectively, compared with 94.5 and 89.1 %, respectively, for fFN test. Positive predictive value, negative predictive value, and accuracy of AmniSure test to diagnose PROM were 98.2, 97.3, and 97.7 %, respectively, compared with 89.7, 94.2, and 91.8 %, respectively, for fFN test. Predictive values and accuracy of fFN test to diagnose PROM were statistically insignificant compared with predictive values and accuracy of ferning, nitrazine and AmniSure tests.
2.Insulin-like growth factor binding protein-1 (Actim PROM test) for detection of premature rupture of fetal membranes.
Abdelazim IA J Obstet Gynaecol Res. 2014 Apr;40(4):961-7. doi: 10.1111/jog.12296. Epub 2014 Feb 26.
AIM: ;This study was designed to detect the accuracy of the insulin-like growth factor binding protein-1 (IGFBP-1) in diagnosing premature rupture of fetal membranes.;MATERIALS AND METHODS: ;A total of 150 pregnant women after 37 weeks' gestation were included in this study and divided into two groups according to presence or absence of premature rupture of the membranes (PROM); 75 patients with PROM were included in group I and 75 patients without PROM were included in group II as controls. The diagnosis of PROM was based on patient's history of sudden gush of water, pooling of amniotic fluid, positive Ferning pattern, positive Nitrazine test, confirmed by visualization of fluid passing from the cervical canal during sterile speculum examination and transabdominal ultrasound to measure the amniotic fluid index.;RESULTS: ;In this study, the sensitivity and the specificity of IGFBP-1 (Actim PROM test) in diagnosing PROM were 89.3% and 82.7%, respectively, as compared with 84% sensitivity and 78.7% specificity for Ferning test, and 86.7% sensitivity and 81.3% specificity for Nitrazine test. The positive predictive value (PPV) and negative predictive value (NPV) of IGFBP-1 were 83.8% and 88.
3.The VI-SENSE-vaginal discharge self-test to facilitate management of vaginal symptoms.
Geva A;Bornstein J;Dan M;Shoham HK;Sobel JD Am J Obstet Gynecol. 2006 Nov;195(5):1351-6. Epub 2006 Jun 12.
OBJECTIVE: ;This study was undertaken to evaluate a diagnostic panty liner (VI-SENSE) (Common Sense, Caesarea, Israel) developed to facilitate diagnosis of vaginal infections by detecting disordered acidity level.;STUDY DESIGN: ;Five hundred sixteen women with vulvovaginal symptoms were enrolled. Final clinical diagnosis included Amsel criteria, Gram stain analysis, pH determination, and Trichomonas vaginalis and Candida culture. VI-SENSE strip color status estimated by patients was compared with clinical diagnosis and pH measurement by using nitrazine paper. Statistical analysis included sensitivity and specificity calculations.;RESULTS: ;The VI-SENSE test was positive in 226 of 249 patients (90.8%) with bacterial vaginosis or trichomoniasis. Nitrazine pH paper revealed elevated pH in 165 (66.5%) and the amine test was positive in 160 (64.3%) patients. The VI-SENSE test was negative in 217 of 267 patients (81.3%) without trichomoniasis or bacterial vaginosis. The VI-SENSE was positive in 85 of 92 women (92%), with mixed vaginal infection including Candida and bacterial vaginosis or trichomoniasis. Amine test, nitrazine pH paper and physician diagnosis relying only on speculum examination were inferior and positive in only 65 (70%), 59 (64%), and 66 (72%) patients, respectively.
