The Effect of Glyceryl Trinitrate on Hypertension in Women with Severe Preeclampsia, HELLP Syndrome, and Eclampsia

Objective: The goal of this study is to evaluate the effect of glyceryl trinitrate (GTN) in the management of hypertension in women with preeclampsia, eclampsia, and HELLP syndrome. Study Design: Fifty five women with preeclampsia, eclampsia, and HELLP syndrome administered GTN infusion for the management of hypertension were studied. Demographic, clinical, and perinatal outcome findings were collected for analyses. We recorded initial and maintenance doses of GTN, and duration of its use in prepartum and postpartum periods. We collected systolic and diastolic blood pressures (BPs) at admission and before the administration of GTN infusion. During the GTN infusion, we calculated average diastolic and systolic blood pressures 6 hours apart on the first day, 12 hours apart on the second day, and 24 hours apart on the third day. Results: Of 55 women, 24 with severe preeclampsia, 16 with HELLP syndrome, and 15 with eclampsia were included in this study. In severe preeclampsia group, GTN infusion significantly reduced systolic and diastolic BPs beginning from the second quarter and third quarter, respectively, of first day (p < 0.05). In the HELLP syndrome group, GTN infusion significantly decreased systolic and diastolic blood pressures beginning from the third quarter and second quarter, respectively, of the first day (p < 0.05). In the eclampsia group, GTN infusion significantly reduced systolic and diastolic blood pressures beginning from the third quarter and first quarter, respectively, of the first day (p < 0.05). Conclusion: In women with severe preeclampsia, eclampsia, and HELLP syndrome, infusion of GTN can be used as an alternative agent to well‐known drugs and causes no significant adverse effect to the mother and fetus.

Immunohistochemistry with apoptotic-antiapoptotic proteins (p53, p21, bax, bcl-2), c-kit, telomerase, and metallothionein as a diagnostic aid in benign, borderline, and malignant serous and mucinous ovarian tumors

BackgroundIn many tumors including ovarian cancer, cell proliferation and apoptosis are important in pathogenesis and there are many alterations in most of the genes related to the cell cycle. This study was designed to evaluate immunohistochemistry with apoptotic-antiapoptotic proteins (p53, p21, bax, and bcl-2), c-kit, telomerase, and metallothionein as a diagnostic aid in typing of benign, borderline, and malignant serous and mucinous ovarian tumors.MethodsTotal of 68 ovarian tumors, 25 benign [13 (19.1%) serous and12 (17.6%) mucinous], 16 borderline [9 (13.2%) serous and 7(10.3%) mucinous], and 27 malignant ovarian tumors [24 (35.3%) serous and 3 (4.4%) mucinous tumors] were included in the study. Immunohistochemical expression of p53, p21, bax, bcl–2, telomerase, c-kit, and metallothionein were evaluated.ResultsWhen all 68 cases were evaluated as benign, borderline, and malignant ovarian tumors without considering histopathological subtypes, the p53, p21, bax and metallothionein showed significantly higher staining scores in the borderline and malignant ones (p < 0.05). After evaluation of all 68 cases, the serous tumors showed significantly higher staining scores of p53, p21, c-kit, and metallothionein compared to the mucinous ones (p < 0.05). For differentiation of benign and borderline and malignant tumors combined, p53 was not used because all benign tumors has no staining, and p21, bax, and metallothionein was determined the significant predictors for borderline and malignant tumors combined (p < 0.05). For differentiation of borderline and malignant tumors, only p53 was determined the significant predictor for malignant tumors (p < 0.05).ConclusionsIn conclusion, p53, p21, bax, c-kit, and metallothionein may be helpful for the typing of ovarian tumors as benign, borderline and malignant or serous and mucinous. p53, p21, bax, c-kit, and metallothionein may have different roles in the pathogenesis of ovarian tumor types. p53 and metallothionein may be helpful in the typing of borderline and malignant ovarian tumors. The immunohistochemical staining with bcl-2 and telomerase may not provide meaningful contribution for the typing of ovarian tumors.Virtual slideThe virtual slides for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/2013030833768498

Identification of yeasts in public hospital primary care patients with or without clinical vaginitis.

Objective:  Vaginal yeast infections are one of the most common female genital tract infections. Candida albicans is the most common infectious cause. Candida species other than C. albicans are being diagnosed with increasing frequency. The aim of the present study was to determine species of yeasts obtained from the vaginal fluid among public hospital primary care patients with or without clinical vaginitis and to evaluate the correlation of vaginal yeast colonisation with epidemiological and clinical features of applicants.

A Placebo-Controlled Comparison of Effects of Repetitive Doses of Betamethasone and Dexamethasone on Lung Maturation and Lung, Liver, and Body Weights of Mouse Pups

The aim of this study was to compare in vivo effects of single and repetitive doses of betamethasone (BETA) and dexamethasone (DEX) administered to pregnant mice on lung maturation and lung, liver, and body weights (LLBW) of their pups. One hundred and eighty gravid Swiss albino mice were randomly assigned to 1 of 6 groups (n = 30) and administered either BETA, DEX, or saline as a single dose at 14 d gestation or repetitive doses twice daily at 14 and 15 d gestation. All the study groups were then divided into three sets (n = 10). The mice in the second sets were redivided into three subsets randomly (including four, three, and three mice). All gestations in the first sets were terminated at 16.5 d gestation to observe the neonatal breathing pattern (scale to 0–5; 5 is unlabored breathing) of male and female pups whereas other sets had normal delivery. The pups in first, second, and third sets were killed for evaluation in the first set after the evaluation of breathing pattern, in the subsets of second set on postnatal d 1, 3, and 5, and in the third set on postnatal d 90. We recorded maternal body weights at 0 and 16.5 d gestation, and LLBW, the lung/body weight ratio of pups, sex, and the amount of live and dead births per litter. Pups exposed to BETA and DEX had significantly lower maternal weight compared with the saline groups. The death litter size was significantly higher in pups exposed to repetitive doses of DEX than the other treatments. Sex had no significant effect on breathing score and LLBW. Pups exposed to repetitive doses of BETA and DEX presented a higher breathing score than the other groups. The breathing score was significantly higher with BETA than DEX after their repetitive use. The LLBW were significantly less in the treatment groups, especially in the group exposed to repetitive doses of DEX. In conclusion, repetitive doses of BETA and DEX lead to increased fetal lung maturation, but this may be at the expense of fetal and neonatal growth. DEX is less potent in accelerating lung maturation than BETA but it causes more reduction in fetal and neonatal growth.

The role of transvaginal sonography in predicting recurrent preterm labour in patients with intact membranes

Our purpose was to determine whether funnelling of the cervical internal os, length of the endocervical canal, cervical index, funnel length and funnel width determined by transvaginal sonography are predictive of recurrent preterm labour. Of 112 women, 65 admitted to the hospital for preterm labour with intact membranes had transvaginal sonographic evaluation of the cervix before digital cervical examination and institution of tocolysis. The following measurements were obtained: (1) presence of funnelling, (2) endocervical canal length, (3) cervical index, (4) funnel length and (5) funnel width. Logistic regression analysis was performed to determine the variables that made a significant contribution to the prediction of recurrent preterm labour. A total of 65 eligible women completed the study. Recurrent preterm labour was significantly associated with the presence of funnelling (85.2% vs. 23.3%) and short endocervical canal length, large cervical index and long funnel length as noted on transvaginal cervical sonography. The presence of funnelling, shorter endocervical canal length, larger cervical index and longer funnel length were suggestive of true preterm labour and its recurrence. Transvaginal sonographic examination of the uterine cervix is a useful procedure to predict recurrent preterm labour with intact membranes.

Diagnostic and Therapeutic Decision- Making With Transvaginal Sonography for First Trimester Spontaneous Abortion, Clinically Thought To Be Incomplete or Complete

The purpose of this study was to evaluate the diagnostic accuracy of transvaginal sonography for first trimester spontaneous abortions, thought to be incomplete or complete, in patients with postabortion bleeding or uterine cramping within 5 days of abortion. In a prospective study, 78 patients underwent transvaginal sonography to evaluate the maximum anteroposterior diameter of the uterine cavity on the long axis view and echo pattern of the retained products of conception. Patients were divided into three groups: those with a normal uterine cavity or a uterine cavity with fluid collection without echogenic foci (n = 13, group A), those with a uterine cavity containing fluid mixed with solid components (n = 38, group B), and those with a uterine cavity containing solid components (n = 27, group C). Group A was considered not to have retained products of conception, and the latter two groups were considered to have retained products of conception. Patients in group A were assigned to receive conservative treatment. In groups B and C, patients with significant vaginal bleeding during 48 h of follow-up underwent elective curettage and those with minimal-mild bleeding received conservative management. A total of 73 patients (12 in group A, 35 in group B and 26 in group C) completed the study. There were no differences in any of selected reproductive data of the groups (p > 0.05). In group B, all patients with uterine cavity diameter of 10 mm or greater underwent elective curettage. In group C, all patients with a diameter of the uterine cavity 8 mm or greater underwent elective curettage. The overall complication and patient satisfaction rates were approximately 14% and 88%, respectively. Transvaginal sonographic findings can be used as a decision factor in the management of patients with first trimester spontaneous abortion to reduce the need for an elective curettage by approximately 58%.

Effect of deep injections of local anesthetics and basal dilatation of cervix in management of pain during legal abortions. A randomized, controlled study.

The present study was designed to investigate whether deep injections of local anesthetics provide better pain control than regular injections of local anesthetics, and to evaluate the influence of basal cervical dilatation and dilatation increase obtained on the painfulness of abortion procedure during legal abortions. A total of 66 women undergoing legal abortion were randomly allocated to treatment with deep injection (n = 31) or regular injection (n = 35) group. Subjects in the deep injection group had paracervical block involving four injections approximately 3 cm deep. Subjects assigned to the regular injection group had paracervical block involving four injections approximately 1.5 cm deep. A pain scale was administered at the end of the dilatation and end of curettage. Both groups were found to be similar with respect to age, parity, previous legal abortion, gestational age, anxiety score, procedure time, basal cervical dilatation, and dilatation increase obtained. The mean pain score during cervical dilatation was less for the deep injection versus the regular injection group (3.3 +/- 1.5 versus 4.0 +/- 1.6, p < 0.05). The mean pain score during curettage was significantly less for the deep injection versus the regular injection group (3.0 +/- 1.2 versus 3.9 +/- 1.4, p < 0.05). In conclusion, deep injection of local anesthetics is a safe adjunct in the management of legal abortion. Irrespective of injection technique, dilatation pain is correlated negatively with basal cervical dilatation and correlated positively with dilatation increase obtained.

Use of methylene blue and N,O-carboxymethylchitosan to prevent postoperative adhesions in a rat uterine horn model

OBJECTIVES To compare the anti-adhesion potential of 1% methylene blue (MB) solution and 2% N,O-carboxymethylchitosan (NOCC) gel in a rat uterine horn model. DESIGN Experimental animal study. SETTING University medical center. ANIMAL(S) Forty female Wistar albino rats randomized into four groups. INTERVENTION(S) We examined the effects of 1% MB solution and 2% NOCC gel to reduce the extent and severity of postoperative adhesions in a rat uterine horn model: no adjuvant therapy in control group, 2 mL of normal saline (NS) solution in NS group, 2 mL of 1% MB solution in MB group, and 2 mL of 2% NOCC gel in NOCC group was instilled onto uterine horns of the rats. MAIN OUTCOME MEASURE(S) Adhesions were scored according to their extent and severity. RESULT(S) The extent and severity scores of adhesions in MB and NOCC groups were significantly lower than those of control and NS groups. There was no statistically significant difference between the extent and severity scores of adhesions between MB and NOCC groups. CONCLUSION(S) These findings suggest that MB and 2% NOCC gel should be considered as an adjuvant in the prevention of postoperative intra-abdominal adhesions. Future experimental and clinical studies are required to find their optimal formulation and usage.
