To investigate the efficacy of oral misoprostol administered to facilitate tandem application to the cervix as a part of brachytherapy in patients with cervical cancer. Eighty patients with cervical cancer who had been planned to undergo brachytherapy at Dr. Lütfi Kırdar Kartal Training and Research Hospital were evaluated in a double-blind, prospective, randomized trial. Patients were divided randomly into two groups of 40 patients. The first and second groups received 400 μg of misoprostol orally and placebo, respectively, 3 h before tandem application. The two groups were compared in terms of age, diameter of tumor, parity, age at first intercourse, amount of bleeding and pain at first tandem application, length of endometrial cavity measured by hysterometer, and size of Hegar dilators used for cervical dilatation. Of all cases, 63.6%, 16.3%, 10%, 6.3%, 2.5%, and 1.3% were Stage IIB, IIIB, IIIA, IVA, IIA and IIC, respectively. Mean (±SD) age (range) was 49.3 ± 13.1 (25-83) years and 56.6 ± 13.2 (30-78) years in the study and control groups, respectively (p = 0.015). Age at first intercourse, diameter of tumor, parity, amount of bleeding at first tandem application, and length of endometrial cavity measured by hysterometer were not significantly different between the two groups. Pain score was significantly higher in the control group (p < 0.001). Application was significantly easier in the study group compared with controls (p < 0.001). Average size of initial Hegar dilators used for cervical dilatation was significantly higher in the study group compared with controls (p = 0.017). Administration of misoprostol 400 μg orally for cervical ripening before tandem application facilitates the procedure, increases patient tolerability and comfort, and may decrease complication rates.

To evaluate the side effects of 600 microg misoprostol orally during the first 24 hours after administration in the third stage of labour. Double blind randomised controlled trial. Tertiary care hospitals in Nigeria and Thailand. All women participating in the WHO Misoprostol trial in these two hospitals between January 1, 1999 and June 17, 1999. All women were followed up during the first 24 hours postpartum to evaluate the occurrence of shivering, nausea, vomiting, diarrhoea and other misoprostol-related side effects. Rates of shivering, nausea, vomiting, diarrhoea and pyrexia within 1 hour and in the intervals 2-6, 7-12, 13-18 and 19-24 hours after delivery. A total of 1686 women were enrolled. Women who received misoprostol had higher incidence than the oxytocin group of 'any' shivering in the first hour (RR 6.4, 95% CI 3.9 to 10.4) and the period covering 2-6 hours following delivery (RR 4.7, 95% CI 1.9 to 11.2). Pyrexia was also more common in the misoprostol group in both the same time intervals (RR 2.8, 95% CI 1.4 to 5.3 and RR 6.3, 95% CI 3.7 to 10.8, respectively). Diarrhoea was not present in the first hour in either group but appeared in the second time period (2-6 hours) and third time period (7-12 hours) more frequently in the misoprostol group than with oxytocin. The increased incidence of shivering and pyrexia that occurs with postpartum use of misoprostol persists up to 6 hours following delivery. Approximately 5% of women experience diarrhoea that starts after 1 hour and subsides within 12 hours.

To systematically review the efficacy of misoprostol compared with placebo or other uterotonics in preventing maternal morbidity associated with the third stage of labor. We identified, retrieved, evaluated, abstracted data, and assessed the quality of all published studies (from January 1996 to May 2002) which assessed misoprostol's efficacy in minimizing uterine blood loss during the third stage of labor. Seventeen studies included 28170 subjects; of these, approximately one-half received misoprostol with the remainder receiving either a placebo or another uterotonic agent. An estimate of the odds ratio (OR) and risk difference for dichotomous outcomes was calculated using a random- and fixed-effects model. Continuous outcomes were pooled using a variance-weighted average of within-study difference in means. In assessing studies comparing misoprostol with placebo, those who received oral misoprostol had a decreased risk of needing additional uterotonics (OR 0.64, 95% confidence interval 0.46, 0.90). Compared with placebo, use of misoprostol was associated with an increased risk for shivering and pyrexia. In contrast, in studies comparing misoprostol with oxytocin, oxytocin was associated with significantly lower rates of postpartum hemorrhage, maternal shivering and pyrexia. In studies comparing misoprostol with Syntometrine, misoprostol was associated with higher rates of the need for additional uterotonic agent as well as shivering. Misoprostol was inferior to oxytocin and other uterotonics with regard to any of the third stage of labor outcomes assessed. However, when compared to placebo, misoprostol had a decreased risk of needing additional uterotonics. Thus, in less-developed countries where administration of parenteral uterotonic drugs may be problematic, misoprostol represents a reasonable agent for the management of the third stage of labor. Additional randomized clinical trials examining objective outcome measures (i.e. need for blood transfusion or 10

. The allocated medication (misoprostol and placebo) was self-administered 1 h or 3 h prior to surgery. All women received 2 tablets of 200 mcg misoprostol and 2 identical looking placebo tablets. Prophylactic pain medication, 100 mg oral diclofenac, was administered at the time of misoprostol. Side effects were recorded immediately before surgery and women were asked which administration route of administration they found most convenient and which they would have preferred. The exact priming time (from misoprostol administration to initiation of dilatation) and signs of bleeding prior to dilatation were recorded. Vacuum aspiration was performed under general anaesthesia according to clinical routine. Dilatation was performed using tapered Pratt-dilatators and the resistance of the cervix was assessed objectively using a tonometer. All surgery was performed by two investigators, experienced in using the tonometer. The cumulative force required to dilate the cervix was calculated by adding the peak force needed for each dilatator up to 9.7 mm. The time needed for surgery including cervical dilatation and vacuum aspiration, was recorded. Intra-operative blood loss was measured and any surgical complications noted. Six women were excluded retrospectively from the analysis. Multivariate analysis of the primary outcome baseline dilatation showed a significant influence on route of administration (P = 0.034, 95% confidence interval (CI) -2.202, -0.086) as well as the interaction variable between route of administration and total priming time (P = 0.042, 95% CI 0.00, 0.016), with the vaginal route becoming more effective with longer priming time. These factors also had a significant influence on the peak force (administration route P = 0.042, 95% CI 0.221, 12.427, interaction P = 0.049, 95% CI -0.089, 0.000) and cumulative force (administration route P = 0.023, 95% CI 3.142, 40.877, interaction P = 0.026, 95% CI -0.293, -0.019) used for dilatation.

This article presents an overview of four studies that evaluated a continuous oral contraceptive (OC) containing levonorgestrel (90 mcg) and ethinyl estradiol (20 mcg; LNG/EE) for managing premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS). Three randomized, double-blind, placebo-controlled trials and one open-label, single-treatment substudy examined mean changes from baseline in the Daily Record of Severity of Problems (DRSP) or Penn Daily Symptom Rating (DSR). Improvements from baseline in mean DRSP and DSR scores were observed, but results were not consistent among the studies. Mean percent improvement of premenstrual symptoms ranged from 30% to 59% in controlled trials and 56% to 81% in an open-label substudy. A large placebo effect was also observed in the placebo-controlled studies. Continuous LNG/EE yielded a favorable safety profile. These data, although not consistent, indicate that continuous LNG/EE may reduce the symptoms of PMDD and PMS, providing an option for women who are appropriate candidates for a continuous OC as a contraceptive, the approved indication for this medication.

To compare the efficacy and safety of mifepristone followed by misoprostol with misoprostol alone in the management of early pregnancy failure (EPF). A randomized double-blind placebo-controlled clinical trial. Ninety-two women with EPF ≤12 weeks were recruited and randomly allocated to receive either mifepristone 200 mg ( n  = 46) or placebo ( n  = 46). Forty-eight hours later, patients in both the groups were given 800 µg misoprostol per-vaginum. If no expulsion occurred within 4 h, repeat doses of 400 µg misoprostol were given orally at 3-hourly interval to a maximum of 2 doses in women ≤9 weeks by scan and 4 doses in women >9 weeks by scan. Pre-treatment of misoprostol with mifepristone significantly increased the complete abortion rate (86.7 vs. 57.8%, p  = 0.009) and, hence, reduced the need for surgical evacuation (13.3 vs. 42.2%, p  = 0.002), induction to expulsion interval (4.74 ± 2.24 vs. 8.03 ± 2.77 h, p  = 0.000), mean number of additional doses of misoprostol required (0.68 vs. 1.91, p  = 0.000), and side effects. Use of mifepristone prior to misoprostol in EPF significantly improves the efficacy and reduces the side effects of misoprostol alone.

To investigate the side effects of 600 microg oral misoprostol given for the mother and the newborn to prevent postpartum hemorrhage (PPH). One thousand six hundred twenty women delivering at home or subcentres in rural India were randomised to receive misoprostol or placebo in the third stage of labour. Women were evaluated for shivering, fever, nausea, vomiting and diarrhea at 2 and 24 h postpartum. Newborns were evaluated within 24 h for diarrhea, vomiting and fever. Symptoms were graded as absent, mild-to-moderate or severe. Women who received misoprostol had a significantly greater incidence of shivering (52%vs. 17%, p < 0.001) and fever (4.2%vs. 1.1%, p < 0.001) at 2 h postpartum compared with women who received placebo. At 24 h, women in the misoprostol group experienced significantly more shivering (4.6%vs. 1.4%, p < 0.001) and fever (1.4%vs. 0.4%, p < 0.03). There were no differences in nausea, vomiting or diarrhea between the two groups. There were no differences in the incidence of vomiting, diarrhea or fever for newborns. Misoprostol is associated with a significant increase in postpartum maternal shivering and fever with no side effects for the newborn. Given its proven efficacy for the prevention of PPH, the benefits of misoprostol are greater than the associated risks.

Medical abortion regimens based on the use of either misoprostol alone or in association with mifepristone have shown high efficacy and excellent safety profile in early pregnancy abortion. However, no clear recommendation is available for late first-trimester termination of pregnancy. A prospective randomized controlled trial included 122 women seeking medical abortion at 9 to 12 weeks of gestation. Seventy-three patients were given a fixed protocol of 200 mg of mifepristone followed 48 h later by 400 mcg oral misoprostol (Group 1). The second group of 49 patients was administered 800-mcg intravaginal single-dose misoprostol (Group 2). This study sought to compare safety, efficacy and acceptability of these two nonsurgical abortion regimens. Fifty-nine (80.8%) women in Group 1 had complete abortion vs. 38 (77.4%) women in Group 2 (p=.66). Abdominal pain was observed significantly more often in Group 2 (35/49 (71.4%) vs. 32/73 (43.8%) in Group 1, p<.0001. Medical abortion was equally acceptable among the two groups [37/49 (75.5%) and 55/73 (75.7%), p=.89]. For late first-trimester termination, a single 800-mcg vaginal dose of misoprostol seems to be as effective as the mifepristone+misoprostol regimen, with acceptable side effects.

The study was conducted to evaluate bleeding profile and safety of continuous oral contraceptive (OC) containing levonorgestrel (LNG) 90 mcg/ethinyl estradiol (EE) 20 mcg. Healthy women who participated at seven Canadian sites in 1-year open-label study of LNG 90 mcg/EE 20 mcg daily were eligible for this second-year extension study. Primary end points included bleeding profile and adverse events. Seventy-nine women enrolled without interrupting pill taking; 62 (78.5%) completed. Adverse events were comparable to cyclic OC regimens, except unscheduled vaginal bleeding. Amenorrhea and absence of bleeding increased to about 80% and 90%, respectively, by Pill Pack 18. Mean (median) number of bleeding days for the last two 90-day intervals was 1.1 (0) and 0.7 (0) days, respectively. Continuous LNG 90 mcg/EE 20 mcg had a safety profile similar to low-dose cyclic OCs. Short-term safety profile remained excellent, with increasing rates of amenorrhea and decreasing incidence of unscheduled bleeding and/or spotting. Copyright © 2010 Elsevier Inc.

The study was aimed to evaluate the effectiveness, outcome, and pain intensity of the vaginal administration of misoprostol for the induction of abortion between 13 and 24 gestational weeks. A retrospective study was conducted at our tertiary medical center from January 2006 to December 2009 on 122 consecutive women who underwent termination of pregnancy (TOP) in the mid-trimester. They were given 400 mcg of vaginal misoprostol every 6h, up to four doses. The induction-to-abortion interval and the level of pain experienced during the process were assessed. Success was defined by the fetus being expelled within 48 h. Vaginal misoprostol was effective in 84% (98/122) of patients. The median duration of the induction-to-abortion interval was 16 (5-48)h. The induction-to-abortion interval was correlated with gestational age, while inversely correlated with parity. A correlation was also found between gestational age and pain intensity at 12h from induction. Misoprostol is safe and effective in mid-trimester abortion induction. The induction-to-abortion interval is shorter and abortion less painful with lower gestational age. Higher parity is also associated with shorter induction to abortion interval. Copyright © 2011.

To compare the efficacy of oral misoprostol with that of oxytocin for active management of the third stage of labor (AMTSL). A double-blind randomized control trial was undertaken at a center in Ilorin, Nigeria, between January and June 2013. Every other eligible patient (in the first stage of labor at term, to have a spontaneous vaginal delivery, and no/low risk of postpartum hemorrhage [PPH]) were randomly assigned with computer-generated random numbers to receive oral misoprostol (600μg) plus placebo injection or oral placebo plus oxytocin injection (1mL of 10IU) in the third stage of labor. The primary outcome was amount of blood loss during delivery. Mean postpartum blood loss was 325.85±164.72mL in the 100 patients given misoprostol and 303.95±163.33mL in the 100 patients given oxytocin (P=0.391). PPH (≥500mL blood loss) was recorded in 15 (15.0%) patients given misoprostol and 14 (14.0%) given oxytocin (P=0.841). Shivering, pyrexia, and diarrhea were all significantly more common in the misoprostol group (P<0.01 for all). The efficacy of oral misoprostol was similar to that of intramuscular oxytocin. Adverse effects associated with misoprostol were transient and self-limiting. Thus, oral misoprostol is efficacious and a good alternative to oxytocin for AMTSL.

Oral contraceptive pills (OCs) are a commonly prescribed method of birth control for sexually experienced adolescents. The purpose of the current study was to describe anticipated parental involvement and adolescent compliance with pill taking, and to describe experiences with a 20-mcg OC regarding satisfaction and side effects after six cycles. Anticipated parental involvement and anticipated compliance, and experiences with an OC, were assessed at baseline, and after the first and sixth cycles during a clinical trial of oral contraceptives, which required parental consent. Three adolescent medicine clinics in New York, NY; Cincinnati, OH; and San Juan, Puerto Rico. The sample consisted of 43 female adolescents with a mean age of 17 years. The majority of adolescents living with a parent anticipated parental involvement, and few adolescents anticipated difficulties with consistent pill taking. For two side effects (weight and mood changes), more than 30% of the adolescents anticipated the occurrence or worsening of side effects. However, few adolescents actually experienced increases in any of the nine side effects assessed. Ninety-seven percent of adolescents in this trial reported being satisfied with a 20-mcg OC. Health care providers can assess adolescents' anticipated difficulties with compliance with daily pill taking, and desire for help from their parents. This information can be incorporated into counseling to promote consistent and correct use.

To select the misoprostol dose to be used in a large multicentre randomised trial comparing misoprostol with oxytocin in the routine management of the third stage of labour. Randomised pilot trial, double-blinded with the use of double placebos. Two of the nine hospitals that will participate in the main multicentre trial. The hospitals were located in Johannesburg, South Africa and Khon Kaen, Thailand. Women during second stage of labour about to be delivered vaginally. The trial had three arms: misoprostol 400 microg versus misoprostol 600 microg versus intramuscular oxytocin 10 IU. Each group received an injection and three tablets immediately after the birth of the baby. Shivering and pyrexia rates were the main outcome measures. Data on other side effects and characteristics of the third stage of labour were also collected. Side effects were noted as none, mild, moderate or severe. Both shivering and pyrexia (temperature > 38 degrees C) were most common in the 600 microg misoprostol group (28% and 7.5% for shivering and pyrexia, respectively) compared with 400 microg misoprostol (19% and 2%), and the oxytocin group (12.5% and 3%). The increase in shivering in the misoprostol 600 microg group was due primarily to a higher rate of moderate shivering. None of the women had a temperature > 40 degrees C. There were no increases in severe side effects and other adverse events in the misoprostol 600 microg group. When used in the management of the third stage of labour oral misoprostol is associated with an increase in the rate of moderate shivering and pyrexia which seems to be dose-related. Based on the results of this pilot trial, the Steering Committee has decided to use 600 microg misoprostol in the main trial, comparing it with oxytocin, in order to achieve higher effectiveness.

The third stage of labour may be complicated by retained placenta, which should be managed promptly because it may cause severe bleeding and infection, with a potentially fatal outcome. This study evaluated the effectiveness of umbilical vein injection of misoprostol for the treatment of retained placenta in a hospital setting. This hospital-based placebo-controlled trial was conducted at the Maternity Teaching Hospital, Erbil City, Kurdistan region, Northern Iraq from April 2011 to February 2012. The inclusion criteria were: gestational age of at least 28 weeks, vaginal delivery, and failure of the placenta to separate within 30 minutes after delivery of the infant despite active management of the third stage of labour. Forty-six women with retained placentas were eligible for inclusion. After informed consent was obtained, the women were alternately allocated to receive umbilical vein injection of either 800 mcg misoprostol dissolved in 20 mL of normal saline (misoprostol group) or 20 mL of normal saline only (saline group). The women were blinded to the group allocation, but the investigator who administered the injection was not. The trial was registered by the Research Ethics Committee of Hawler Medical University. After umbilical vein injection, delivery of the placenta occurred in 91.3% of women in the misoprostol group and 69.5% of women in the saline group, which was not a significant difference between the two groups. The median vaginal blood loss from the time of injection until delivery of the placenta was significantly less in the misoprostol group (100 mL) than in the saline group (210 mL) (p value < 0.001). Umbilical vein injection of misoprostol is an effective treatment for retained placenta, and reduces the volume of vaginal blood loss with few adverse effects.

To test the effect of 800 μg of misoprostol orally on the prevention of manual removal of retained placenta. Multicenter, double-blinded, placebo-controlled, randomized trial. One university and one non-university teaching hospital in the Netherlands. 99 women with retained placenta (longer than 60 min after childbirth) in the absence of postpartum hemorrhage. Eligible women were administered either 800 μg of misoprostol or placebo orally. Number of manual removals of retained placenta and amount of blood loss. Manual removal of retained placenta was performed in 50% of the women who received misoprostol and in 55% who received placebo (relative risk 0.91, 95% confidence interval 0.62-1.34). No difference in the amount of blood loss (970 vs. 1120 mL; p = 0.34) was observed between the two groups. Administration of 800 μg of oral misoprostol, one hour after childbirth, does not seem to reduce the number of manual removals of retained placentas. The time elapsing results in the delivery of 50% of the retained placentas at the expense of an increased risk of postpartum hemorrhage. © 2013 The Authors Acta Obstetricia et Gynecologica Scandinavica © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

We report our preliminary experience with the use of a low-dose oral contraceptive containing Drospirenone/Ethinylestradiol 3 mg/20 mcg, both in cyclic and continuous regimen for endometriosis management. A total of 93 women were retrospectively included: 52 were treated by medical therapy (exclusive combined oral contraceptives (COC)-users), while 41 were submitted to surgery followed by postoperative therapy (postoperative COC-users). A clinical examination was performed at baseline and at 6-months follow-up. Presence and intensity of endometriosis-related symptoms were assessed by a visual analogue scale. Presence and dimension of endometriotic lesions were evaluated by transvaginal ultrasonography. Adverse effects and tolerability were analysed. In exclusive COC-users, significant reductions in dysmenorrhoea and dyspareunia scores and in endometrioma mean diameter were observed at follow-up. In postoperative COC-users, anatomical and symptom recurrence rates at follow-up were 4.9% and 17%, respectively. The most frequent adverse effects were spotting and headache. No difference between cyclic and continuous regimen in terms of symptom relief, lesion progression and tolerability was observed. From our preliminary experience, Drospirenone/Ethinylestradiol 3 mg/20 mcg seems to be promising in endometriosis management.

Chitral, Khyber Pakhtunkhwa Province, Pakistan. a total of 1119 women giving birth at home. from June 2006 to June 2008, consenting women were randomised to receive 600 microg oral misoprostol (n = 534) or placebo (n = 585) after delivery to determine whether misoprostol reduced the incidence of PPH (≥ 500 ml). the primary outcomes were measured blood loss ≥ 500 ml after delivery and drop in haemoglobin >2 g/dl from before to after delivery. oral misoprostol was associated with a significant reduction in the rate of PPH (≥ 500 ml) (16.5 versus 21.9%; relative risk 0.76, 95% CI 0.59-0.97). There were no measurable differences between study groups for drop in haemoglobin >2 g/dl (relative risk 0.79, 95% CI 0.62-1.02); but significantly fewer women receiving misoprostol had a drop in haemoglobin >3 g/dl, compared with placebo (5.1 versus 9.6%; relative risk 0.53, 95% CI 0.34-0.83). Shivering and chills were significantly more common with misoprostol. There were no maternal deaths among participants. postpartum administration of 600 microg oral misoprostol by trained TBAs at home deliveries reduces the rate of PPH by 24%. Given its ease of use and low cost, misoprostol could reduce the burden of PPH in community settings where universal oxytocin prophylaxis is not feasible. Continual training and skill-building for TBAs, along with monitoring and evaluation of programme effectiveness, should accompany any widespread introduction of this drug.

Abortion, spontaneous or induced, is a common complication of pregnancy and exploration of available and safe regimens for medical abortion in developing countries seems crucial. The present study was aimed to assess the effect of letrozole in combination with misoprostol in women eligible for legal therapeutic abortion with gestational age ≤14weeks. This clinical randomized trial was conducted on 78 women who were candidate of medical abortion and eligible for legal abortion with gestational age ≤14 weeks that were randomly divided into two groups of case and controls. Case group received daily oral dose of 10mg letrozole for three days followed by vaginal misoprostol. In control group the patients received only vaginal misoprostol. The rate of complete abortion, induction-of-abortion time, and side-effects were assessed. Complete abortion was observed in 30 patients (76.9%) in case group and 9 (23.1%) cases were failed. In control group there was 16 (41.03%) complete abortions and 23 (58.97%) cases were failed to abort. Patients with gestational age of between 6 and 10 weeks did not show significant difference in both groups (P=0.134). Regarding pregnancy remnants there were significant differences between two groups (P=0.034). The time form admission to discharge in case groups were significantly shorter than those in control group (P=0.001). The indication for curettage in case group was significantly less than control group (P=0.001). A 3-day course of letrozole (10mg/daily) followed by misoprostol was associated with a higher complete abortion and lower curettage rates and reduction in time from admission to discharge in women with gestational age ≤14 weeks compared to misoprostol alone.

Oral misoprostol, administered by trained health-workers is effective and safe for preventing postpartum haemorrhage (PPH). There is interest in expanding administration of misoprostol by non-health workers, including task-shifting to pregnant women themselves. However, the use of misoprostol for preventing PPH in home-births remains controversial, due to the limited evidence to support self-administration or leaving it in the hands of non-health workers. This study aimed to determine if antenatally distributing misoprostol to pregnant women to self-administer at home birth reduces PPH. Between February 2013 and March 2014, we conducted a stepped-wedge cluster-randomized trial in six health facilities in Central Uganda. Women at 28+ weeks of gestation attending antenatal care were eligible. Women in the control-arm received the standard-of-care; while the intervention-arm were offered 600 mcg of misoprostol to swallow immediately after birth of baby, when oxytocin was not available. The primary outcome (PPH) was a drop in postpartum maternal haemoglobin (Hb) by ≥ 2 g/dl, lower than the prenatal Hb. Analysis was by intention-to-treat at the cluster level and we used a paired t-tests to assess whether the mean difference between the control and intervention groups was statistically significant. 97% (2466/2545) of eligible women consented to participate; 1430 and 1036 in the control and intervention arms respectively. Two thousand fifty-seven of the participants were successfully followed up and 271 (13.2%) delivered outside a health facility. There was no significant difference between the study group in number of women who received a uterotonic at birth (control 80.4% vs intervention 91.4%, mean difference = -11.0%, 95% confidence interval [CI] -25.7% to 3.6%, p = 0.11). No woman took misoprostol before their baby's birth. Shivering and fever were 14.9% in the control arm compared to 22.2% in the intervention arm (mean difference = -7.2%, 95% CI -11.1% to -3

Prevention of postpartum haemorrhage: cost consequences analysis of misoprostol in low-resource settings.

While inferior to oxytocin injection in both efficacy and safety, orally administered misoprostol has been included in the World Health Organization Model List of Essential Medicines for use in the prevention of postpartum haemorrhage (PPH) in low-resource settings. This study evaluates the costs and health outcomes of use of oral misoprostol to prevent PPH in settings where injectable uterotonics are not available. A cost-consequences analysis was conducted from the international health system perspective, using data from a recent Cochrane systematic review and WHO's Mother-Baby Package Costing Spreadsheet in a hypothetical cohort of 1000 births in a mixed hospital (40% births)/community setting (60% births). Costs were estimated based on 2012 US dollars. Using oxytocin in the hospital setting and misoprostol in the community setting in a cohort of 1000 births, instead of oxytocin (hospital setting) and no treatment (community setting), 22 cases of PPH could be prevented. Six fewer women would require additional uterotonics and four fewer women a blood transfusion. An additional 130 women would experience shivering and an extra 42 women fever. Oxytocin/misoprostol was found to be cost saving (US$320) compared to oxytocin/no treatment. If misoprostol is used in both the hospital and community setting compared with no treatment (i.e. oxytocin not available in the hospital setting), 37 cases of PPH could be prevented; ten fewer women would require additional uterotonics; and six fewer women a blood transfusion. An additional 217 women would experience shivering and 70 fever. The cost savings would be US$533. Sensitivity analyses indicate that the results are sensitive to the incidence of PPH-related outcomes, drug costs and the proportion of hospital births. Our findings confirm that, even though misoprostol is not the optimum choice in the prevention of PPH, misoprostol could be an effective and cost-saving choice where oxytocin is not or cannot be used due to a

Two studies assessed the effect of a low-estrogen-dose 21/7-day oral contraceptive containing ethinylestradiol and drospirenone (EE 20 mcg/drsp 3 mg) on ovarian activity in Japanese and Caucasian women. Study 1 was conducted in Japanese women (20-35 years), and Study 2 was conducted in Caucasian women (18-35 years). All women received EE 20 mcg/drsp 3 mg in a 21-day active pill regimen. The primary endpoint was the proportion of women with ovulation inhibition (Hoogland score <6; as assessed by transvaginal ultrasonography) during treatment cycle 2. Japanese (n=23) and Caucasian (n=30) women received two cycles of study treatment. During treatment cycle 2, ovulation was inhibited in 100% and 92.9% of Japanese and Caucasian women, respectively. EE 20 mcg/drsp 3 mg in a 21/7-day regimen provides comparable ovarian suppression in Japanese and Caucasian women, with normal ovarian function resuming shortly after treatment end in both populations.

To assess the interest of misoprostol in gynaecology and particularly for cervical priming. Research in PubMed in English and French about misoprostol and its use in gynaecology. We summarized the results of 3 meta-analyses, randomized controlled trials and literature review. Results show that misoprostol did not scientifically prove a benefit for cervical priming before hysteroscopy or before intra-uterine device (IUD). Results are the same with post-menopausal or nulliparous women. It did not lead either to lower the complications but increase adverse effects. It is not indicated to use misoprostol for cervical priming in gynaecology. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

A combined oral contraceptive containing 30 mcg ethinyl estradiol and 3.0 mg drospirenone does not impair endothelium-dependent vasodilation.

Ethinyl estradiol (EE) increases endothelium-dependent vasodilation in young women, but certain progestins paired with EE in combination oral contraceptive pills (OCPs) have been shown to antagonize the vasodilatory effects of EE. Therefore, the purpose of this study was to investigate how endothelial function, serum biomarkers and resting blood pressures change across an OCP cycle in women using a monophasic OCP formulation containing the progestin drospirenone. Twelve women were studied during two hormone phases of their OCP cycle: once at the end of 3 weeks of active pills (30 mcg EE and 3.0 mg drospirenone) and once at the end of a week of placebo pills (no exogenous hormones) Endothelium-dependent vasodilation was greater during the active phase compared to the placebo phase (p<.001). In contrast, there was no difference in endothelium-independent dilation between hormone phases. These data suggest that the combination of 30 mcg EE and 3.0 mg drospirenone used in the active phase of this OCP increases endothelium-dependent vasodilation compared to a placebo phase.

Reduction of aspirin-induced fecal blood loss with low-dose misoprostol tablets in man

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cohen, M.M.; Clark, L.; Armstrong, L.

Misoprostol (SC-29333), a synthetic prostaglandin E1 methyl ester analog, was given simultaneously with acetylsalicylic acid in a double-blind, placebo-controlled randomized prospective study of 32 healthy human male subjects. Fecal blood loss was measured for eight days using the /sup 51/Cr-labeled red blood cell technique. Aspirin (650 mg qid) and misoprostol (25 micrograms qid) or placebo were given during days 3, 4, and 5. There was a significant (P less than 0.05) increase in median blood loss (modified Friedman test) from 0.81 to 6.05 ml/day in the aspirin with placebo group (N = 16). Median blood loss was increased (from 0.75more » to 3.75 ml/day) in the aspirin with misoprostol group (N = 16), but this was significantly less (Mann-Whitney U test, P less than 0.01) than the placebo group. Mean serum salicylate concentrations in the placebo and misoprostol groups were similar (7.8 and 6.8 micrograms/ml, respectively). There were no significant changes in laboratory values in any of the subjects studied, nor were any major side-effects encountered. This study demonstrates that oral misoprostol reduces aspirin-induced gastrointestinal bleeding even when administered simultaneously and at a dose level below its threshold for significant acid inhibition. This indicates a potential role for misoprostol in the prevention of gastric mucosal damage in selected patients.« less

Access to injectable uterotonics for management of postpartum haemorrhage remains limited in Senegal outside health facilities, and misoprostol and oxytocin delivered via Uniject have been deemed viable alternatives in community settings. We aimed to compare the efficacy of these drugs when delivered by auxiliary midwives at maternity huts. We did an unmasked cluster-randomised controlled trial at maternity huts in three districts in Senegal. Maternity huts with auxiliary midwives located 3-21 km from the closest referral centre were randomly assigned (1:1; via a computer-generated random allocation overseen by Gynuity Health Projects) to either 600 μg oral misoprostol or 10 IU oxytocin in Uniject (intramuscular), stratified by reported previous year clinic volume (deliveries) and geographical location (inland or coastal). Maternity huts that had been included in a previous study of misoprostol for prevention of postpartum haemorrhage were excluded to prevent contamination. Pregnant women in their third trimester were screened for eligibility either during community outreach or at home-based prenatal visits. Only women delivered by the auxiliary midwives in the maternity huts were eligible for the study. Women with known allergies to prostaglandins or pregnancy complications were excluded. The primary outcome was mean change in haemoglobin concentration measured during the third trimester and after delivery. This study was registered with ClinicalTrials.gov, number NCT01713153. 28 maternity hut clusters were randomly assigned-14 to the misoprostol group and 14 to the oxytocin group. Between June 6, 2012, and Sept 21, 2013, 1820 women were recruited. 647 women in the misoprostol group and 402 in the oxytocin group received study drug and had recorded pre-delivery and post-delivery haemoglobin concentrations, and overall 1412 women delivered in the study maternity huts. The mean change in haemoglobin concentrations was 3·5 g/L (SD 16·1) in the misoprostol group

A combined oral contraceptive comprising ethinylestradiol (EE) 20 mcg/drospirenone 3 mg in a 24/4 regimen has been clinically shown to alleviate the symptoms associated with premenstrual dysphoric disorder (PMDD). However, previous studies did not report data according to cycle-by-cycle improvement. This was a subanalysis of a Phase III, double-blind, multicenter, United States-based study. Women with confirmed PMDD were randomized to EE 20 mcg/drospirenone 3 mg 24/4 or placebo for three treatment cycles. Ten of the 21 emotional and physical items on the Daily Record of Severity of Problems scale were grouped to define three symptom clusters: (a) negative emotions, (b) food cravings and (c) water retention-related symptoms. The change from baseline at each treatment cycle was compared between groups using a weighted analysis of covariance model. The full analysis set comprised 449 women. Daily Record of Severity of Problems scores for each symptom cluster were significantly reduced from baseline with both EE 20 mcg/drospirenone 3 mg 24/4 and placebo (p<.0001 for all). The greatest symptom improvements were achieved within the first cycle of treatment and continued throughout cycles 2 to 3. The mean between-treatment difference was significant in favor of EE 20 mcg/drospirenone 3 mg 24/4 for all three symptom clusters in all three treatment cycles (p≤.0001 vs. placebo in percent change from baseline). Ethinylestradiol 20 mcg/drospirenone 3 mg 24/4 improved commonly recognizable PMDD symptom clusters relating to negative emotions, food cravings and water retention-related symptoms to a significantly greater extent than placebo during all three cycles of treatment.

Misoprostol for tinnitus.

PubMed

Crinnion, C L; McCart, G M

1995-01-01

Practitioners should realize that further study of misoprostol in larger patient populations must be undertaken to determine its efficacy and safety in the treatment of tinnitus. Previous approaches to treating tinnitus have included carbamazepine, phenytoin, lidocaine, tocainide, flecainide acetate, alprazolam, and nortriptyline. Studies using lidocaine, nortriptyline, or alprazolam have shown encouraging results. The relative contribution of misoprostol remains to be seen; however, it may offer a new treatment option to patients who have experienced adverse effects or have contraindications to the pharmacologic agents currently available.

To document clinical outcomes and women's experiences following the introduction of mifepristone into South African public sector second-trimester medical abortion services, and compare with historic cohorts receiving misoprostol-only. Repeated cross-sectional observational studies documented service delivery and experiences of women undergoing second-trimester medical abortion in public sector hospitals in the Western Cape, South Africa. Women recruited to the study in 2008 (n = 84) and 2010 (n = 58) received misoprostol only. Those recruited in 2014 (n = 208) received mifepristone and misoprostol. Consenting women were interviewed during hospitalization by study fieldworkers with respect to socio-demographic information, reproductive history, and their experiences with the abortion. Clinical details were extracted from medical charts following discharge. Telephone follow-up interviews to record delayed complications were conducted 2-4 weeks after discharge for the 2014 cohort. The 2014 cohort received 200 mg mifepristone, which was self-administered 24-48 hours prior to admission. For all cohorts, following hospital admission, initial misoprostol doses were generally administered vaginally: 800 mcg in the 2014 cohort and 600 mcg in the earlier cohorts. Women received subsequent doses of misoprostol 400 mcg orally every 3-4 hours until fetal expulsion. Thereafter, uterine evacuation of placental tissue was performed as needed. With one exception, all women in all cohorts expelled the fetus. Median time-to-fetal expulsion was reduced to 8.0 hours from 14.5 hours (p<0.001) in the mifepristone compared to the 2010 misoprostol-only cohort (time of fetal expulsion was not recorded in 2008). Uterine evacuation of placental tissue using curettage or vacuum aspiration was more often performed (76% vs. 58%, p<0.001) for those receiving mifepristone; major complication rates were unchanged. Hospitalization duration and extreme pain levels were reduced (p<0.001), but side

Prostaglandin E 2 (PGE 2 ) is an anti-inflammatory compound that inhibits 5-lipoxygenase activity. Diminished PGE 2 regulation in aspirin-exacerbated respiratory disease (AERD) leads to respiratory reactions on cyclooxygenase 1 inhibition. In vitro studies have found that exogenous PGE 2 stabilizes inflammatory mediator release. To examine whether misoprostol (oral prostaglandin E 1 analogue) use during aspirin challenge and desensitization might decrease the severity of aspirin-induced symptoms and make desensitization safer for patients with AERD. Forty-five patients undergoing aspirin challenge and/or desensitization were randomized to misoprostol (n = 30) or placebo (n = 15) and compared with a group of historical controls (n = 31). Misoprostol (200 μg) was administered at 30 minutes, 90 minutes, and 4 hours after the first dose of nasal ketorolac. Measured end points included change in forced expiratory volume in 1 second (FEV 1 ), peak nasal inspiratory flow rate (PNIF), number of treatments received for induced reactions, and adverse gastrointestinal effects. A difference in FEV 1 and PNIF reduction was detected between misoprostol and placebo (P = .03) and misoprostol and historical controls (P = .01), respectively, during nasal ketorolac challenge. No difference was detected among aspirin reactors. Among all reactors, no difference in magnitude was found for FEV 1 (P = .13) or PNIF (P = .07) reduction across all 3 groups. Total treatment requirement was similar (P = .14). Patients receiving misoprostol were more likely to report adverse gastrointestinal effects (P = .02). The addition of misoprostol to current aspirin challenge and/or desensitization protocols reveals no protective effect in reducing the intensity of nonsteroidal anti-inflammatory drug-induced symptoms and is not recommended based on the findings in this study.

Misoprostol for postpartum hemorrhage prevention at home birth: an integrative review of global implementation experience to date

PubMed Central

2013-01-01

Background Hemorrhage continues to be a leading cause of maternal death in developing countries. The 2012 World Health Organization guidelines for the prevention and management of postpartum hemorrhage (PPH) recommend oral administration of misoprostol by community health workers (CHWs). However, there are several outstanding questions about distribution of misoprostol for PPH prevention at home births. Methods We conducted an integrative review of published research studies and evaluation reports from programs that distributed misoprostol at the community level for prevention of PPH at home births. We reviewed methods and cadres involved in education of end-users, drug administration, distribution, and coverage, correct and incorrect usage, and serious adverse events. Results Eighteen programs were identified; only seven reported all data of interest. Programs utilized a range of strategies and timings for distributing misoprostol. Distribution rates were higher when misoprostol was distributed at a home visit during late pregnancy (54.5-96.9%) or at birth (22.5-83.6%), compared to antenatal care (ANC) distribution at any ANC visit (22.5-49.1%) or late ANC visit (21.0-26.7%). Coverage rates were highest when CHWs and traditional birth attendants distributed misoprostol and lower when health workers/ANC providers distributed the medication. The highest distribution and coverage rates were achieved by programs that allowed self-administration. Seven women took misoprostol prior to delivery out of more than 12,000 women who were followed-up. Facility birth rates increased in the three programs for which this information was available. Fifty-one (51) maternal deaths were reported among 86,732 women taking misoprostol: 24 were attributed to perceived PPH; none were directly attributed to use of misoprostol. Even if all deaths were attributable to PPH, the equivalent ratio (59 maternal deaths/100,000 live births) is substantially lower than the reported maternal

The objective of this study was to compare a Tibetan traditional medicine (the uterotonic Zhi Byed 11 [ZB11]) to oral misoprostol for prophylaxis of postpartum hemorrhage (PPH). We conducted a double-blind randomized controlled trial at three hospitals in Lhasa, Tibet, People’s Republic of China. Women (N = 967) were randomized to either ZB11 or misoprostol groups. Postpartum blood loss was measured in a calibrated blood collection drape. The primary combined outcome was incidence of PPH, defined as measured blood loss (MBL) ≥ 500 mL, administration of open label uterotonics, or maternal death. We found that the rate of the combined outcome was lower among the misoprostol group (16.1% versus 21.8% for ZB11; P = .02). Frequency of PPH was lower with misoprostol (12.4% versus 17.4%; P = .02). There were no significant differences in MBL > 1000 mL or mean or median MBL. Fever was significantly more common in the misoprostol group (P = .03). The rate of combined outcome was significantly lower among women receiving misoprostol. However, other indices of obstetric hemorrhage were not significantly different. PMID:19249659

To investigate the possible protective effect of misoprostol on cisplatin-induced hepatotoxicity. Four-equal sized groups (control, cisplatin-treated, misoprostol-treated, combined misoprostol, and cisplatin-treated) adult male Wistar rats (6 each) were used in this study. Body weight, liver weight, and liver weight/body weight ratio was calculated. Blood samples were obtained from the hearts of rats to determine the levels of total serum bilirubin (TSB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and albumin. Liver specimens were prepared for both light and electron microscopes. The study was carried out between June 2012 and April 2013 at the Anatomy Department, Faculty of Medicine, Zagazig University, Zagazig, Egypt, and the Department of Anatomy, Faculty of Medicine, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia. A single cisplatin dose (7.5 mg/kg intraperitoneally) resulted in significant elevation of AST, ALT, and TSB serum levels, and a significant reduction of serum albumin level, body weight, liver weight, and liver weight/body weight ratio. A combination of misoprostol (200 ug/kg/day) with cisplatin improved most of the previous parameters. Examination of specimens by both light and electron microscopes revealed pericentral hepatic necrosis, periportal fibrosis, dilatation, and congestion of central vein and blood sinusoids, diminished glycogen content, degenerated mitochondria, vesicular dilated rough endoplasmic reticulum, and nuclear changes in cisplatin-treated rats. Oral intake of misoprostol with cisplatin improved many of these changes. The results indicate that misoprostol may have a protective effect on cisplatin-induced hepatotoxicity.

The aim of this study was to describe the typical profile, and to assess the motivations of women who underwent illegal abortion with misoprostol in Guadeloupe (French West Indies). We conducted a 1-year prospective study on women who consulted after failure or complication of an illegal abortion with misoprostol. Fifty-two cases of illegal abortion with misoprostol were recorded. The most common profile was an unemployed woman, who was unmarried, foreign-born, had no medical insurance, and a low level of education; the median age was 28 (range 17 to 40). The justifications given were that the legal procedure was considered to be too slow, the young age of the woman, the ease of the self-medication procedure, a history of illegal abortion by misoprostol in the woman's country of origin, ignorance of the legal process, and financial and/or administrative problems. The problem of illegal abortion is probably underestimated in Guadeloupe and possibly France. This description of the profile of the population concerned and the justifications for choosing illegal abortion by misoprostol provides elements allowing better focus of education concerning abortion, contraception and family planning. Access to legal abortion centers should also be improved. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

The new class of antiinflammatory and analgesic drugs, the selective cyclooxygenase (COX-2) inhibitors, which promise to be devoid of the types of toxicity associated with nonsteroidal antiinflammatory drugs (NSAID), especially adverse gastrointestinal effects, are under clinical trial but are not yet available for use. All NSAID, including those most recently introduced, exhibit nonselectivity of action, producing therapeutic blood levels that inhibit constitutive COX-1 and deplete tissue protective prostaglandins. Among NSAID, the diclofenac/misoprostol combination (Arthrotec) is unique in possessing an active component, misoprostol, to help prevent NSAID induced gastrointestinal damage. Ulcer damage and associated serious complications probably represent only the tip of the iceberg in relation to clinically significant side effects associated with the use of NSAID. In this context, metaanalysis of 8 large multicenter studies reported here has shown that patients taking NSAID show a mean decrease in hemoglobin over 4 - 12 weeks' assessment, with some 10-20% of patients exhibiting clinically significant decreases (> or = 1 g/dl) early in treatment. Patients taking diclofenac/misoprostol showed significantly less of a decline in hemoglobin and up to 50% fewer clinically significant decreases than patients receiving diclofenac alone. The misoprostol component of diclofenac/misoprostol may also help to restore homeostasis in tissues other than the gut. Inhibition of the activity or release of various tissue damaging agents and inflammatory cytokines, e.g., thromboxane and interleukin 1, are described, as are in vivo animal studies that have revealed synergistic or potentiating analgesic and antiinflammatory activities between misoprostol and NSAID, particularly diclofenac. Clinical studies in postsurgical dental pain in more than 500 patients have now shown enhanced analgesia, with greater relief over a longer period, for the diclofenac/misoprostol combination

Combined oral contraceptive (COC) formulations with 20 mcg ethinyl estradiol (EE) have a greater incidence of ovarian hormone production and follicular development, which can be managed by shortening the number of hormone-free days per COC cycle. This study evaluates differences in follicular development during a 7-day versus 4-day hormone-free interval in a COC regimen with 20 mcg EE and 1 mg norethindrone acetate. Forty-one healthy women were randomized in an open-label fashion to this formulation in either a 24/4 or a 21/7 day regimen for three cycles. Estradiol, progesterone, follicle-stimulating hormone, luteinizing hormone and inhibin B were measured daily from Cycle 2, Day 21 to Cycle 3, Day 3 and on Day 7 of Cycle 3. Follicular diameter and Hoogland score were calculated on Cycle 2, Days 21, 24 and 28 and Cycle 3, Days 3 and 7. Sixty-six percent of subjects in the 21/7 group and 70% of the subjects in the 24/4 group developed a follicle greater than 10 mm diameter. Ovarian steroid hormone levels, Hoogland scores and bleeding patterns were not statistically significant between the groups. In contrast to prior studies, this analysis suggests no difference in follicle development or bleeding patterns among women receiving a 21/7 or 24/4 regimen of a 20-mcg EE/1-mg norethindrone acetate COC.

To explore the availability and provision of misoprostol and other medicines for menstrual regulation (MR) among pharmacies in Bangladesh. Between March and November 2011, a cross-sectional study using mystery client visits was conducted among pharmacy workers in Dhaka and Gazipur Districts, Bangladesh. Mystery clients were trained to present 1 of 4 pre-developed situations to pharmacy workers to elicit information on the regimen, adverse effects, and complications of misoprostol use. Mystery clients visited 331 pharmacies. Among the 331 pharmacy workers, 45.8% offered the mystery clients misoprostol and/or other medicines for MR; 25.7% referred them to private clinics or hospitals. Only 7% recommended an effective regimen of misoprostol for MR; 65% suggested administering vaginal and oral misoprostol together. Overall, 72.4% did not provide any advice on complications; the remainder suggested visiting trained providers for complications. Counseling on excessive bleeding as a danger sign was provided by 46% of pharmacy workers. Most (94%) did not provide or refer for post-MR family planning. Pharmacy workers in urban Bangladesh are providing ineffective drugs and regimens for MR. A training package is needed to strengthen service delivery by providing accurate information, high-quality products, and referral mechanisms for women seeking MR through pharmacies. © 2013.

Off-label use of misoprostol in gynaecology

Clinical use of drugs is approved for specified clinical indication, route of administration, dose and population group. Off-label prescribing of a registered medicine occurs outside of these parameters and may be justified by pharmacology and physiology, as well as sufficient evidence from published clinical trials and reviews. Misoprostol and mifepristone in combination have recently been registered in Australia for medical termination of pregnancy in women of child-bearing age. There is good clinical evidence for efficacy and safety of misoprostol in uterine evacuation in both miscarriage and termination of pregnancy. The pharmacological effects of misoprostol on the uterus and clinical outcomes in both early miscarriage and abortion are comparable. Medical management of miscarriage with misoprostol in Australia is performed off-label. A woman presenting with first trimester miscarriage must be clearly informed that use of misoprostol in her case is for a non-approved indication. This raises the issue of inequity in her management compared with that of first trimester medical abortion, including being treated off-label and the potential cost of non-subsidised medication. The clinician must also be careful to use an evidence-based protocol that would withstand medicolegal challenge in the case of an adverse outcome. PMID:27729972

Recent efforts to prevent post-partum haemorrhage (PPH) in low-income countries have focused on providing women with access to oral misoprostol during home birth. The WHO recommends using lay health workers (LHWs) to administer misoprostol in settings where skilled birth attendants are not available. This review synthesizes current knowledge about the barriers and facilitators affecting implementation of advance community distribution of misoprostol to prevent PPH, where misoprostol may be self-administered or administered by an LHW.We searched for and summarized available empirical evidence, and collected primary data from programme stakeholders about their experiences of programme implementation.We present key outcomes and features of advanced distribution programmes that are in operation or have been piloted globally. We categorized factors influencing implementation into those that operate at the health system level, factors related to the community and policy context and those factors more closely connected to the end user.Debates around advance distribution have centred on the potential risks and benefits of making misoprostol available to pregnant women and community members during pregnancy for administration in the home. However, the risks of advance distribution appear manageable and the benefits of self-administration, especially for women who have little chance of expert care for PPH, are considerable. © The Author 2015.

To explore what triggers an elevated body temperature of > or =40.0 degrees C in some women given misoprostol, a prostaglandin E1 analogue, for postpartum haemorrhage (PPH). Post hoc analysis. One tertiary-level hospital in Quito, Ecuador. A cohort of 58 women with a fever of above 40 degrees C following treatment with sublingual misoprostol (800 micrograms) for PPH. Side effects were documented for 163 Ecuadorian women given sublingual misoprostol to treat their PPH. Women's body temperatures were measured, and if they had a fever of > or =40.0 degrees C, measurements were taken hourly until the fever subsided. Temperature trends were analysed, and the possible physiological mechanisms by which postpartum misoprostol produces a high fever were explored. The onset, duration, peak temperatures, and treatments administered for cases with a high fever. Fifty-eight of 163 women (35.6%) treated with misoprostol experienced a fever of > or =40.0 degrees C. High fevers followed a predictable pattern, often preceded by moderate/severe shivering within 20 minutes of treatment. Body temperatures peaked 1-2 hours post-treatment, and gradually declined over 3 hours. Fevers were transient and did not lead to any hospitalisation. Baseline characteristics were comparable among women who did and did not develop a high fever, except for known previous PPH and time to placental expulsion. An unexpectedly high rate of elevated body temperature of > or =40.0 degrees C was documented in Ecuador following sublingually administered misoprostol. It is unclear why temperatures > or =40.0 degrees C occurred with a greater frequency in Ecuador than in other study populations using similar treatment regimens for PPH. Pharmacogenetic studies may shed further light on variations in individuals' responses to misoprostol.

Background: Induction of labour is the process of initiating the labour by artificial means from 24 weeks of gestation. The main aim of this study is to find out the maternal and foetal outcomes after induction of labour with misoprostol and oxytocin beyond 37 weeks of gestation. Methods: This was a hospital-based observational study carried out at Paropakar Maternity and Women’s Hospital, Nepal. Misoprostol of 25 µg was inserted in posterior fornix of vagina or oxytocin infusion was started from 2.5 units on whom induction was decided. Maternal and foetal/neonatal outcomes were observed. Collected data were analysed using SPSS and MS Excel. Results: General induction rate was found to be 7.2%. In this study, post-term pregnancy was found to be the most common reason for induction of labour. Analysis of onset of labour led to the finding that mean onset of labour was much rapid in oxytocin (6.6 h) than misoprostol (13.6 h). However, there is similarity in induction–delivery interval in both groups. Overall, the rate of normal delivery and caesarean section was found to be 64.9% and 33.2%, respectively. Similarly, normal delivery within 12 h was seen in 18.4% of the patients given with misoprostol and 43.5% in oxytocin group. Foetal distress was found as the most common reason for caesarean section. The overall occurrence of maternal complication was found to be similar in misoprostol and oxytocin groups, nausea/vomiting being the most common (36.7%) complication followed by fever (24.1%). Besides this, the most common neonatal complication found in overall cases was meconium stained liquor (49.2%). Conclusion: It was found that misoprostol was used most frequently for induction of labour compared to oxytocin. The onset of labour was found to be rapid in oxytocin than misoprostol. However, the occurrence of side effects was found to be similar in both misoprostol and oxytocin groups. PMID:28540049

Community-based distribution of misoprostol for prevention of postpartum hemorrhage (PPH) in resource-poor settings has been shown to be safe and effective. However, global recommendations for prenatal distribution and monitoring within a community setting are not yet available. In order to successfully translate misoprostol and PPH research into policy and practice, several critical points must be considered. A focus on engaging the community, emphasizing the safe nature of community-based misoprostol distribution, supply chain management, effective distribution, coverage, and monitoring plans are essential elements to community-based misoprostol program introduction, expansion, or scale-up.

To compare the safety and efficacy of misoprostol and oxytocin for induction of labor. One hundred thirty women requiring induction of labor were randomized to receive either intravenous oxytocin or 100 micrograms misoprostol, administered intravaginally every 4 hours until labor was established. Compared with women receiving oxytocin, a greater percentage of women in the misoprostol group had Bishop scores of 3 or less (58 versus 38%, P < .05). Nonetheless, the median induction-to-delivery interval was significantly shorter (585 versus 885 minutes, P < .001) in the misoprostol group. Women in the misoprostol group were more likely to deliver vaginally within 24 hours of the start of induction (77 versus 55%, P < .002). Epidural analgesia was used more frequently in women receiving oxytocin than in those receiving misoprostol (73 versus 50%, P = .025). The total percentage of cesarean deliveries was not significantly different, although the percentage of cesarean deliveries for dystocia was lower in the misoprostol group (8 versus 21%, P = .02). Uterine tachysystole was significantly more common (70 versus 11%, P < .001) and hospital charges significantly less with misoprostol. Compared with oxytocin for labor induction, misoprostol results in a shorter induction-to-delivery interval, a reduction in the rate of cesarean delivery for dystocia, and a decreased use of epidural analgesia. Uterine tachysystole is significantly more common with the use of misoprostol.

Contraction frequency after administration of misoprostol in obese versus nonobese women.

To examine impact of obesity on contraction frequency following misoprostol. Our hypothesis is that an increased volume of distribution reduces the bioavailability of misoprostol and may be an explanation for reduced efficacy. We examined the contraction frequency as a surrogate marker for bioavailability of misoprostol. We compared the rate of contractions at five time intervals in 313 subjects: prior to administration, and at four intervals post administration. We compared number of contractions in obese versus nonobese. As a planned secondary analysis, we then compared the rate of change in contractions per hour at four time intervals: a repeated measures analysis to compare the rate of change in contractions per hour over the 5-hour window controlling for race (White versus non-White) and parity (primiparous versus multiparous). General linear model and repeated measures analysis were conducted to report the parameter estimates, least square means, difference of least square means, and p values. Nonobese women presented with more contractions at baseline, 7 ± 5 versus 4 ± 5 c/h, p < .001. At all four time intervals after misoprostol administration obese women had fewer contractions per hour. The rate of change in contraction frequency after administration found obese women had a lower rate of increase in contraction frequency over the course of all four hours. We found a least squares means estimate (c/h): first hour (-0.87), p = .08, second hour (-2.43), p = .01, third hour (-1.80), p = .96, and fourth hour (-2.98), p = .007. Obese women have a lower rate of contractions per hour at baseline and at four intervals after misoprostol administration. In addition, the rate of change in the increase in contractions/hour also was reduced in obese women versus nonobese women. This suggests a lower bioavailability of misoprostol in women with a larger volume of distribution which would likely impact the efficacy of misoprostol in obese

Estroprogestins (EPs) are combinations of estrogen and progestin with several actions on women's health. The different pharmacological composition of EPs is responsible for different clinical effects. One of the most used low-dose EP associations is ethinylestradiol 20 mcg plus levonorgestrel 100 mcg in monophasic regimen (EE20/LNG100). This review summarizes clinical pharmacology, cycle control, and effects on lipid and glucose metabolism, coagulation, body weight/body composition, acne, and sexuality of EE20/LNG100. Overall, EE20/LNG100 combination is safe and well tolerated, and in several studies the incidence of adverse events in the treated group was comparable to that of the placebo group. Cycle control was effective and body weight/body composition did not vary among treated and untreated groups in most studies. The EE20/LNG100 combination shows mild or no effect on lipid and glucose metabolism. Lastly, EE20/LNG100 is associated with a low risk of venous thromboembolism (VTE). In conclusion, in the process of decision making for the individualization of EPs choice, EE20/LNG100 should be considered for its favorable clinical profile.

The objective of this study was to evaluate the effect of three contraceptive pills containing ethinylestradiol (EE) (20 or 30 mcg) in combination with drospirenone (DRSP) and levonorgestrel (LNG) on plasma concentration of adhesion molecules vascular cell adhesion molecule -1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1) and E-selectin. A cross-sectional study was conducted with 72 participants (18-30 years old) distributed into three groups that used oral contraceptives containing EE 20 or 30 mcg combined with DRSP 3 mg or EE 30 mcg/LNG 150 mcg for at least 6 months. The control group was comprised of nonusers of contraceptives. Soluble VCAM-1, soluble ICAM-1 and soluble E-selectin were evaluated by enzyme-linked immunosorbent assay. Compared to the control group, a significant decrease was found in VCAM-1 and ICAM-1 concentrations with use of DRSP/20 EE and LNG/30 EE. DRSP/20 EE and LNG/30 EE induce favorable changes in endothelial function. Copyright © 2012 Elsevier Inc. All rights reserved.

Misoprostol has a wide range of applications in obstetrics and gynaecology. It is widely recommended by WHO, FIGO and ACOG for the treatment of postpartum haemorrhage due to it safety and cost-effectiveness. However, usage might be associated to hyperpyrexia and shivering. We present a 30 year old Cameroonian female gravida 1 para 1 who had a vaginal delivery at 40 weeks of gestation complicated by primary postpartum haemorrhage (PPH). PPH was managed by sublingual misoprostol that induced shivering and hyperpyrexia managed successfully with paracetamol and cooling. The occurrence of fever and shivering should be kept in mind when administering misoprostol for PPH.

Rethinking WHO guidance: review of evidence for misoprostol use in the prevention of postpartum haemorrhage

This article describes and critically appraises clinical trials assessing misoprostol effectiveness in preventing primary postpartum haemorrhage (PPH) in home and community settings in low- and middle-income countries. Of 172 identified studies of misoprostol use in labour only six fulfilled the inclusion criteria. All trials used 600μg misoprostol in the intervention arm; three assessed misoprostol alongside components of active management of the third-stage labour (AMTSL), two used expectant management of labour and one allowed birth attendants to choose management practice. The three AMTSL studies showed no significant differences in PPH incidence or referral to higher centres and only one study showed significant decrease in severe PPH using misoprostol. One expectant management study and the choice of management by birth attendants study found significant decreases in PPH incidence with misoprostol. All studies showed significantly increased risk of shivering with misoprostol. Studies were biased by use of alternative uterotonics in the control arm, confounding management practices, and subjective assessment and, with one exception, exclusion of high-risk women. PPH incidence fell in both the control and intervention groups in both the landmark papers that informed the World Health Organization (WHO) decision to admit misoprostol to the Essential Medicines List. This suggests factors other than misoprostol use are crucial. Current evidence does not support misoprostol use in home and community settings in low- and middle-income countries for PPH prevention. WHO should rethink its recent decision to include misoprostol on the Essential Medicines List. PMID:22907551

Making misoprostol widely available for management of postpartum haemorrhage (PPH) and post abortion care (PAC) is essential for reducing maternal mortality. Private pharmacies (thereafter called "pharmacies") are integral in supplying medications to the general public in Senegal. In the case of misoprostol, pharmacies are also the main supplier to public providers and therefore have a key role in increasing its availability. This study seeks to understand knowledge and provision of misoprostol among pharmacy workers in Dakar, Senegal. A cross-sectional survey was conducted in Dakar, Senegal. 110 pharmacy workers were interviewed face-to-face to collect information on their knowledge and practice relating to the provision of misoprostol. There are low levels of knowledge about misoprostol uses, registration status, treatment regimens and side effects among pharmacy workers, and corresponding low levels of training on its uses for reproductive health. Provision of misoprostol was low; of the 72% (n = 79) of pharmacy workers who had heard of the product, 35% (n = 27) reported selling it, though rarely for reproductive health indications. Almost half (49%, n = 25) of the respondents who did not sell misoprostol expressed willingness to do so. The main reasons pharmacy workers gave for not selling the product included stock outs (due to product unavailability from the supplier), perceived lack of demand and unwillingness to stock an abortifacient. Knowledge and availability of misoprostol in pharmacies in Senegal is low, posing potential challenges for delivery of post-abortion care and obstetric care. Training is required to address low levels of knowledge of misoprostol registration and uses among pharmacy workers. Barriers that prevent pharmacy workers from stocking misoprostol, including weaknesses in the supply chain and stigmatisation of the product must be addressed. Low reported sales for reproductive health indications also suggest limited prescribing of

Misoprostol was used by women across Mexico to induce abortion even before 2007, when first-trimester abortion was legalized in Mexico City. Pharmacy vendors' misoprostol recommendation practices across subregions of Mexico after abortion legalization warrant examination. Overall, 192 pharmacies in four regions of Mexico were randomly selected and visited by simulated clients presenting three scenarios (a young woman, an adult woman and a male partner). Bivariate and multivariate analyses were used to explore associations between pharmacy, vendor and client characteristics and drug access. In 558 encounters with simulated clients, 78% of vendors provided information about misoprostol-18% recommended it spontaneously and 60% recommended it only after the client asked specifically for the drug. Fifteen percent of vendors recommended a potentially effective misoprostol dosing regimen. Mexico City-based pharmacies and those in the Central region were significantly less likely than those in the North region to require a prescription to sell misoprostol (odds ratios, 0.2 and 0.3, respectively). Independent pharmacies and those from low-?income areas were significantly more likely to sell misoprostol by the pill than chain pharmacies and those in medium-income areas (3.2 and 2.7, respectively). Access to misoprostol is influenced by neighborhood socioeconomic level, pharmacy location and pharmacy type. The frequently inaccurate and incomplete information provided to clients about using misoprostol for abortion suggests the need to improve pharmacy vendor training in medication abortion options and to develop ways to directly inform women about misoprostol use.

To present the experience of management of second trimester pregnancy termination by misoprostol after failure to abort within 48 h of its use. A retrospective, cohort descriptive study was carried out in the Department of Obstetrics and Gynecology, Faculty of Medicine, Chiang Mai University Thailand between 1998 and 2010. All women at 14-28 weeks of gestation who failed to abort using misoprostol within 48 h were included. Management of failed pregnancy termination among these women is described here. Of a total of 680 women undergoing termination of pregnancy, 68 (10%) failed to abort. Mean maternal age was 28.71 years and mean gestational age was 19.91 weeks. Further management after failure included additional administration of misoprostol only (19.1%), modified condom balloon technique only (17.7%), modified condom balloon technique plus other methods (16.1%), while 47.1% needed only oxytocin as necessary. The mean interval between initiation of termination and delivery was 96.97 h.   Failure of pregnancy termination using misoprostol can be successfully managed by introducing additional misoprostol, modified condom balloon technique and oxytocin infusion. These methods should be considered before proceeding to hysterotomy. © 2012 The Authors. Journal of Obstetrics and Gynaecology Research © 2012 Japan Society of Obstetrics and Gynecology.

Advance distribution of misoprostol for prevention of postpartum hemorrhage (PPH) at home births in two districts of Liberia

PubMed Central

2014-01-01

Background A postpartum hemorrhage prevention program to increase uterotonic coverage for home and facility births was introduced in two districts of Liberia. Advance distribution of misoprostol was offered during antenatal care (ANC) and home visits. Feasibility, acceptability, effectiveness of distribution mechanisms and uterotonic coverage were evaluated. Methods Eight facilities were strengthened to provide PPH prevention with oxytocin, PPH management and advance distribution of misoprostol during ANC. Trained traditional midwives (TTMs) as volunteer community health workers (CHWs) provided education to pregnant women, and district reproductive health supervisors (DRHSs) distributed misoprostol during home visits. Data were collected through facility and DRHS registers. Postpartum interviews were conducted with a sample of 550 women who received advance distribution of misoprostol on place of delivery, knowledge, misoprostol use, and satisfaction. Results There were 1826 estimated deliveries during the seven-month implementation period. A total of 980 women (53.7%) were enrolled and provided misoprostol, primarily through ANC (78.2%). Uterotonic coverage rate of all deliveries was 53.5%, based on 97.7% oxytocin use at recorded facility vaginal births and 24.9% misoprostol use at home births. Among 550 women interviewed postpartum, 87.7% of those who received misoprostol and had a home birth took the drug. Sixty-three percent (63.0%) took it at the correct time, and 54.0% experienced at least one minor side effect. No serious adverse events reported among enrolled women. Facility-based deliveries appeared to increase during the program. Conclusions The program was moderately effective at achieving high uterotonic coverage of all births. Coverage of home births was low despite the use of two channels of advance distribution of misoprostol. Although ANC reached a greater proportion of women in late pregnancy than home visits, 46.3% of expected deliveries did not

Uterotonic coverage rate of all deliveries was 53.5%, based on 97.7% oxytocin use at recorded facility vaginal births and 24.9% misoprostol use at home births. Among 550 women interviewed postpartum, 87.7% of those who received misoprostol and had a home birth took the drug. Sixty-three percent (63.0%) took it at the correct time, and 54.0% experienced at least one minor side effect. No serious adverse events reported among enrolled women. Facility-based deliveries appeared to increase during the program. The program was moderately effective at achieving high uterotonic coverage of all births. Coverage of home births was low despite the use of two channels of advance distribution of misoprostol. Although ANC reached a greater proportion of women in late pregnancy than home visits, 46.3% of expected deliveries did not receive education or advance

Post-partum hemorrhage (PPH) is the most common direct cause of maternal mortality and timely intervention can save many lives. To compare the effectiveness of sublingual misoprostol to intravenous oxytocin in preventing post-partum hemorrhage in low risk vaginal birth. One hundred patients with no risk factor for PPH were randomly allocated to receive 600 μg misoprostol administered sublingually or 10 IU of intravenous oxytocin immediately after the delivery of baby. Main outcome measures were post-partum blood loss, drop in hemoglobin in 24 h, duration of third stage of labor, and drug-related adverse effects. Mean age, parity and gestational age were similar in both groups. Mean blood loss was significantly lower in oxytocin group (114.28 ± 26.75 versus 149.50 ± 30.78 ml; p = 0.00). Drop in hemoglobin was 0.31 ± 0.16 versus 0.49 ± 0.21 g% (p = 0.01) in oxytocin and misoprostol group, respectively. Duration of third stage labor was shorter in oxytocin group (median 5 min, IQR: 4.5-5.5 versus 5.5 min, IQR: 5-6 min, p < 0.01). Although fever and shivering were common adverse effects with misoprostol but were not clinically significant. Intravenous oxytocin is more efficacious than sublingual misoprostol in preventing PPH in institutional deliveries.

Objective To compare the efficacy and safety of misoprostol alone with dinoprostone followed by misoprostol, all inserted intravaginally in induction of labor at term and the obstetrical outcome. Material and Methods A pilot study comprising 111 primigravidae, >37 gestational weeks with singleton pregnancy in cephalic presentation having an unfavorable Bishop score admitted for labor induction, were considered and randomly allocated into two groups. In group I (n=55) with intravaginal 25mcg misoprostol 4 hourly (six doses at the most) and and group II (n=56), with dinoprostone 0.5mg followed eight hours later by 25mcg misoprostol induction to vaginal delivery time was found to be significantly different, being 14.8 h in group-I and shorter in group-II with a mean of 11.6 h. Vaginal delivery rates within 12 h (groups-I and −II: 47.2%, as compared to 60.7%, respectively) were found to be higher with dinoprostone-misoprostol induction, as well as vaginal delivery rates in 24 h, 80.0% and 91.1%. The need for oxytocin augmentation was more frequent in the misoprostol than in the dinoprostone-misoprostol group, (61.8%, and 39.3%), and all these observations were statistically significant. Abnormal foetal heart rate pattern occurred more frequently (18.2%) in group-I in contrast to 5.3% in group-II, as was the incidence rate of (18.2%) who had passage of meconium in group-I, this rate being significantly different from group-II having meconium passage in 3 cases, a rate of 5.3%. Conclusion Using dinoprostone followed by vaginal misoprostol is safe and effective for induction of labor with less need for oxytocin augmentation and shorter induction delivery interval.

Misoprostol (Cytotec) is recognised to be effective for many gynaecological indications including termination of pregnancy, management of miscarriage and postpartum haemorrhage. Although not licensed for such indications, it has been used for these purposes by millions of women throughout the world. Misoprostol tablets are most often packaged as multiple tablets within an aluminium strip, each within an individual alveolus. When an alveolus is opened, tablets will be exposed to atmospheric conditions. To compare the pharmaco technical characteristics (weight, friability), water content, misoprostol content and decomposition product content (type A misoprostol, type B misoprostol and 8-epi misoprostol) of misoprostol tablets Cytotec (Pfizer) exposed to air for periods of 1 hour to 720 hours (30 days), to those of identical non exposed tablets. Four hundred and twenty (420) tablets of Cytotec (Pfizer) were removed from their alveoli blister and stored at 25°C/60% relative humidity. Water content, and misoprostol degradation products were assayed in tablets exposed from 1 to 720 hours (30 days). Comparison was made with control tablets (N=60) from the same batch stored in non-damaged blisters. Statistical analyses were carried out using Fisher's exact test for small sample sizes. By 48 hours, exposed tablets demonstrated increased weight (+4.5%), friability (+1 300%), and water content (+80%) compared to controls. Exposed tablets also exhibited a decrease in Cytotec active ingredient dosage (-5.1% after 48 hours) and an increase in the inactive degradation products (+25% for type B, +50% for type A and +11% for 8-epi misoprostol after 48 hours) compared to controls. Exposure of Cytotec tablets to 'typical' European levels of air and humidity results in significant time-dependent changes in physical and biological composition that could impact adversely upon clinical efficacy.

To determine the optimal timing of vaginal misoprostol administration in nulliparous women undergoing office hysteroscopy. Randomized double-blind placebo-controlled study. University teaching hospital. One hundred twenty nulliparous patients were randomly allocated in a 1:1 ratio to the long-interval misoprostol group or the short-interval misoprostol group. In the long-interval misoprostol group, two misoprostol tablets (400 μg) and two placebo tablets were administered vaginally at 12 and 3 hours, respectively, before office hysteroscopy. In the short-interval misoprostol group, two placebo tablets and two misoprostol tablets (400 μg) were administered vaginally 12 and 3 hours, respectively, before office hysteroscopy. The severity of pain was assessed by the patients with the use of a 100-mm visual analog scale (VAS). The operators assessed the ease of the passage of the hysteroscope through the cervical canal with the use of a 100-mm VAS as well. Pain scores during the procedure were significantly lower in the long-interval misoprostol group (37.98 ± 13.13 vs. 51.98 ± 20.68). In contrast, the pain scores 30 minutes after the procedure were similar between the two groups (11.92 ± 7.22 vs. 13.3 ± 6.73). Moreover, the passage of the hysteroscope through the cervical canal was easier in the long-interval misoprostol group (48.9 ± 17.79 vs. 58.28 ± 21.85). Vaginal misoprostol administration 12 hours before office hysteroscopy was more effective than vaginal misoprostol administration 3 hours before office hysteroscopy in relieving pain experienced by nulliparous patients undergoing office hysteroscopy.

The aim of this study was to quantify the effects of inhomogeneities on magnetocardiography (MCG) forward solutions. A numerical model of a human torso was used which construction included geometry for major anatomical structures such as subcutaneous fat, skeletal muscle, lungs, major arteries and veins, and the bones. Simulations were done with a single current dipole placed at different sites of heart. The boundary element method (BEM) was utilized for numerical treatment of magnetic field calculations. Comparisons of the effects of different conductivity on MCG forward solution followed one of two basic schemes: (1) consider the difference between the magnetic fields of the homogeneous torso model and the same model with one inhomogeneity of a single organ or tissue added; (2) consider the difference between the magnetic fields of the full inhomogeneous model and the same model with one inhomogeneity of individual organ or tissue removed. The results of this study suggested that accurate representation of tissue inhomogeneity has a significant effect on the accuracy of the MCG forward solution. Generally lungs, subcutaneous fat, skeletal muscle play a larger role than other tissues. Our results showed that the inclusion of the boundaries also had effects on the topology of the magnetic fields and on the MCG inverse solution accuracy.

To report on a rigorous distribution and monitoring plan to track misoprostol for community-based distribution to reduce postpartum haemorrhage (PPH) in rural Ghana. Operations research. Rural Ghana. Women in third trimester of pregnancy presenting to primary health centres (PHCs) for antenatal care (ANC). Ghana Health Service (GHS), Millennium Village Projects, and the University of Illinois at Chicago conducted an operations research study designed to assess the safety, feasibility, and acceptability of community-based distribution of misoprostol to prevent PPH at home deliveries in rural Ghana. One thousand doses (3000 tablets, 200 μg each) were obtained from the Family Health Division of GHS. Three 200-μg tablets of misoprostol (600 μg) in foil packets were packaged together in secured transparent plastic packets labelled with pictorial messages and distributed to midwives at seven PHCs for distribution to pregnant women. Correct use of misoprostol in home deliveries and retrieval of unused misoprostol doses, PPH rates and maternal mortality. Of the 999 doses distributed to midwives, 982 (98.3%) were successfully tracked, with a 1.7% lost to follow-up rate. Midwives distributed 654 doses to women at third-trimester ANC visits. Of women who had misoprostol to use at home, 81% had an institutional delivery and were able to return the misoprostol safely to the midwife. Of the women that used misoprostol, 99% used the misoprostol correctly. This study clearly demonstrates that misoprostol distributed antenatally to pregnant women can be used accurately and reliably by rural Ghanaian women, and should be considered for policy implementation across Ghana and other countries with high home birth rates and maternal mortality ratios. © 2013 Royal College of Obstetricians and Gynaecologists.

The aim of the study was to assess the efficacy and acceptability of a regimen using mifepristone and buccal misoprostol with unlimited dosing for second trimester abortion in Armenia. Women seeking to terminate 13-22 week pregnancies were enrolled in the study. Participants swallowed 200 mg mifepristone in the clinic and were instructed to return to the hospital for induction 24-48 h later. During induction, women were given 400 μg buccal misoprostol every 3 h until the fetus and placenta were expelled. The abortion was considered a success if complete uterine evacuation was achieved without oxytocin or surgery. A total of 120 women with a median gestational age of 18 weeks participated in the study. All women began misoprostol induction around 24 h after taking mifepristone. Complete uterine evacuation was achieved in 119 (99.2%) women. The median induction-to-abortion interval was 10.3 h (range 4-17.4) with a mean of 9.5 ± 2.5 h. A median of four misoprostol doses (range 2-6) with a mean of 4 ± 1 misoprostol doses were administered. The induction-to-abortion interval, number of misoprostol doses, pain score and analgesia use increased as gestational age advanced. Acceptability of the method was high among both patients and providers. The medical abortion regimen of 200 mg mifepristone followed 24 h later by induction with 400 μg buccal misoprostol administered every 3 h, with no limit on the number of doses used for the termination of pregnancies of 13-22 weeks' gestation is an effective and acceptable option for women.

Background: Post-partum hemorrhage (PPH) is a common cause of maternal mortality in developing countries. This trial was conducted to study the effectiveness and safety of rectal misoprostol for PPH. Aim: To assess the effectiveness and safety of misoprostol and comparing with oxytocin for prevention of PPH. Materials and Methods: Women were randomized to receive either two 200 μg rectal misoprostol tablets (study group) or 20 units oxytocin in 1000 cc normal saline intravenously (control group). The outcomes were incidence of PPH, amount of blood loss, duration of labor, incidence of side effects, pre- and post-delivery hemoglobin, and use of additional uterotonics. Finding: The incidence of PPH was 12% in the study group and 10% in the control group (P > 0.05). No significant difference was observed between the groups hematocrit (P > 0.05). Other variables including severe PPH and duration of the third stage of labor were similar in both groups. Conclusion: Rectal misoprostol was as effective as intravenous oxytocin for preventing post-partum hemorrhage with the same incidence of side effects and is recommended to be use as an uterotonic agent to manage third stage of labor routinely.

Induction of COX-2 activity in cerebral ischemia results in increased neuronal injury and infarct size. Recent studies investigating neurotoxic mechanisms of COX-2 demonstrate both toxic and paradoxically protective effects of downstream prostaglandin receptor signaling pathways. We tested whether misoprostol, a PGE(2) receptor agonist that is utilized clinically as an anti-ulcer agent and signals through the protective PGE(2) EP2, EP3, and EP4 receptors, would reduce brain injury in the murine middle cerebral artery occlusion-reperfusion (MCAO-RP) model. Administration of misoprostol, at the time of MCAO or 2h after MCAO, resulted in significant rescue of infarct volume at 24 and 72h. Immunocytochemistry demonstrated dynamic regulation of the EP2 and EP4 receptors during reperfusion in neurons and endothelial cells of cerebral cortex and striatum, with limited expression of EP3 receptor. EP3-/- mice had no significant changes in infarct volume compared to control littermates. Moreover, administration of misoprostol to EP3+/+ and EP3-/- mice showed similar levels of infarct rescue, indicating that misoprostol protection was not mediated through the EP3 receptor. Taken together, these findings suggest a novel function for misoprostol as a protective agent in cerebral ischemia acting via the PGE(2) EP2 and/or EP4 receptors.

This paper reports the feasibility of measuring weak magnetic fields generated by the electrical activity of the heart using a portable tri-axial fluxgate magnetometer inside a magnetically shielded room. Measurement of Magnetocardiogram (MCG) signals could be successfully demonstrated from a healthy subject using a novel set-up involving a reference fluxgate sensor which simultaneously measures the magnetic fields associated with the ECG waveform measured on the same subject. The timing information provided by R wave peaks of ECG recorded by the reference sensor is utilized to generate trigger locked average of the sensor output of the measurement fluxgate, and extract MCG signals in all the three orthogonal directions (X, Y and Z) on the anterior thorax. It is expected that such portable room temperature measurements using fluxgate sensor could assist in validating the direction of the equivalent current dipole associated with the electrical activity of the human heart. This is somewhat difficult in conventional MCG measurements using SQUID sensors, which usually furnish only the z component of the magnetic field and its spatial derivatives.

To systematically review published data evaluating the comparative use of misoprostol with placebo/expectant management or oxytocin for labor induction in women with term (> or = 36 weeks of gestation) premature rupture of membranes. PubMed (1966-2005), Ovid (1966-2005), CINAHL, The Cochrane Library, ACP Journal Club, OCLC, abstracts from scientific forums, and bibliographies of published articles were searched using the following keywords: premature rupture of membranes, misoprostol, labor induction, and cervical ripening. Primary authors were contacted directly if the data sought were unavailable or only published in abstract form. Only randomized controlled trials evaluating the efficacy and safety of misoprostol in comparison with placebo or expectant management (n = 6) and oxytocin (n = 9) published in either article or abstract form were analyzed and included in the meta-analysis. Studies were reviewed independently by all authors. Meta-analysis was performed, and the relative risks (RRs) were calculated and pooled for each study outcome. Misoprostol, compared with placebo, significantly increased vaginal delivery less than 12 hours (RR 2.71, 95% confidence interval [CI] 1.87-3.92, P < .001). Misoprostol was similar to oxytocin with respect to vaginal delivery less than 24 hours (RR 1.07, 95% CI 0.88-1.31, P = .50) and less than 12 hours (RR 0.98, 95% CI 0.71-1.35, P = .90). Misoprostol was not associated with an increased risk of tachysystole, hypertonus, or hyperstimulation syndrome when compared with oxytocin and had similar risks for adverse neonatal and maternal outcomes. Misoprostol is an effective and safe agent for induction of labor in women with term premature rupture of membranes. When compared with oxytocin, the risk of contraction abnormalities and the rate of maternal and neonatal complications were similar among the 2 groups.

A combined oral contraceptive containing 30 mcg ethinyl estradiol and 3.0 mg drospirenone does not impair endothelium-dependent vasodilation

Background Ethinyl estradiol (EE) increases endothelium-dependent vasodilation in young women, but certain progestins paired with EE in combination OCPs have been shown to antagonize the vasodilatory effects of EE. Therefore, the purpose of this study was to investigate how endothelial function, serum biomarkers, and resting blood pressures change across an OCP cycle in women using a monophasic OCP formulation containing the progestin drospirenone. Study Design Twelve women were studied during two hormone phases of their OCP cycle; once at the end of three weeks of active pills (30 mcg EE and 3.0 mg drospirenone), and once at the end of a week of placebo pills (no exogenous hormones). Results Endothelium-dependent vasodilation was greater during the active phase compared to the placebo phase (p < 0.001). In contrast, there was no difference in endothelium-independent dilation between hormone phases. Conclusion These data suggest that the combination of 30 mcg EE and 3.0 mg drospirenone used in the active phase of this OCP increases endothelium-dependent vasodilation compared to a placebo phase.

Efficacy of misoprostol for the treatment of postpartum hemorrhage: current knowledge and implications for health care planning.

Prata, Ndola; Weidert, Karen

2016-01-01

A myriad of interventions exist to treat postpartum hemorrhage (PPH), ranging from uterotonics and hemostatics to surgical and aortic compression devices. Nonetheless, PPH remains the leading cause of maternal mortality worldwide. The purpose of this article is to review the available evidence on the efficacy of misoprostol for the treatment of primary PPH and discuss implications for health care planning. Using PubMed, Web of Science, and GoogleScholar, we reviewed the literature on randomized controlled trials of interventions to treat PPH with misoprostol and non-randomized field trials with controls. We discuss the current knowledge and implications for health care planning, especially in resource-poor settings. The treatment of PPH with 800 μg of misoprostol is equivalent to 40 IU of intravenous oxytocin in women who have received oxytocin for the prevention of PPH. The same dose might be an option for the treatment of PPH in women who did not receive oxytocin for the prevention of PPH and do not have access to oxytocin for treatment. Adding misoprostol to standard uterotonics has no additional benefits to women being treated for PPH, but the beneficial adjunctive role of misoprostol to conventional uterotonics is important in reducing intra- and postoperative hemorrhage during cesarean section. Misoprostol is an effective uterotonic agent in the treatment of PPH. Clinical guidelines and treatment protocols should be updated to reflect the current knowledge on the efficacy of misoprostol for the treatment of PPH with 800 μg sublingually.

To assess the effects of 400-μg sublingual misoprostol plus routine uterotonics on postpartum hemorrhage. A double-blind, placebo-controlled, randomized study was performed. After delivery of the child, eligible women received routine uterotonics and were randomly allocated to receive 400-μg misoprostol or placebo sublingually. The primary outcome measure was blood loss of at least 500 mL within 1 hour of taking the trial tablets. In total, 672 women received misoprostol and 673 received placebo. The baseline data were similar for both groups. Misoprostol plus routine uterotonics reduced postpartum blood loss, but the effect was not significant for blood loss of at least 500 mL (relative risk [RR] 0.96; 95% confidence interval [CI], 0.63-1.45) or blood loss of at least 1000 mL (RR 0.50; 95% CI, 0.15-1.66). Misoprostol also reduced the need for non-routine oxytocin, manual removal of the placenta, and hysterectomy, but these differences were not significant either. Misoprostol was associated with pyrexia and moderate/severe shivering. There was no death in either group. Misoprostol plus routine uterotonics resulted in modest reductions of blood loss in the third stage of labor, but the effects did not reach statistical significance. Larger studies are recommended.

Fever is a well-known side effect of misoprostol, but clinically difficult to distinguish from an intra uterine infection. The aim of this study was to determine the incidence of fever in terminations of pregnancy (TOP) using misoprostol and to evaluate fever as indication of intra uterine infection. A retrospective cohort study was performed. Consecutive second trimester TOP with misoprostol between January 2008 and October 2012 were selected. We included 403 cases and determined the incidence of fever. To examine intra uterine infection as plausible cause of fever, pathological examination reports of placentas were reviewed for signs of infections. The incidence of fever was 42%. Logistic regression showed a dose dependent association between dosage misoprostol and degree of fever (OR 1.86; 95% CI: 1.3-2.7). There was no association between fever and epidural analgesia. Fever has a sensitivity of 55% and a specificity of 58% as a marker of intra uterine infection. The positive predictive value of fever for an intra uterine infection is 4% and the negative predictive value is 98%. Administration of misoprostol for the indication TOP is strongly associated with fever during labor. Fever is a poor predictor of intra uterine infection in the context of TOP.

However, very little is understood on the metabolisms and ecological roles of this cosmopolitan sedimentary archaea , partly due to obstacles of cultivation. Bathyarchaeota could be divided into large members of subgroups with potentially high genetic heterogeneity, implying different metabolic capabilities and functions in different subgroups. Here, we report our work on investigating Bathyarchaeota abundance and types of subgroups in the South China Sea(SCS) sediments, aim to understand their ecological roles in the carbon cycling. Bathyarchaeota were found the most dominant archaeal group in the sediments of SCS , most of which belong to subgroups MCG-8, MCG-15, MCG-17 and MCG-3. A new pair of 16S rRNA gene primers was designed as the published primers could not cover MCG-15 and MCG-17, which are the most dominant subgroups in the SCS sediments. Comparing with previous primers which used for quantifying the abundance of Bathyarchaeota via Q-PCR, the new primer revealed about an order of magnitude higher abundance in all South China Sea sediments. The relationship of geochemical parameters and MCG subgroups will further be explored to provide the basis for further understanding the metabolic function and biogeochemical roles of these poor-understood sedimentary archaea.

Background In settings where home birth rates are high, prenatal distribution of misoprostol has been advocated as a strategy to increase access to uterotonics during the third stage of labor to prevent postpartum hemorrhage (PPH). Our objective was to project the potential cost-effectiveness of this strategy in Uganda from both governmental (the relevant payer) and modified societal perspectives. Methods and Findings To compare prenatal misoprostol distribution to status quo (no misoprostol distribution), we developed a decision analytic model that tracked the delivery pathways of a cohort of pregnant women from the prenatal period, labor to delivery without complications or delivery with PPH, and successful treatment or death. Delivery pathway parameters were derived from the Uganda Demographic and Health Survey. Incidence of PPH, treatment efficacy, adverse event and case fatality rates, access to misoprostol, and health resource use and cost data were obtained from published literature and supplemented with expert opinion where necessary. We computed the expected incidence of PPH, mortality, disability adjusted life years (DALYs), costs and incremental cost effectiveness ratios (ICERs). We conducted univariate and probabilistic sensitivity analyses to examine robustness of our results. In the base-case analysis, misoprostol distribution lowered the expected incidence of PPH by 1.0% (95% credibility interval (CrI): 0.55%, 1.95%), mortality by 0.08% (95% CrI: 0.04%, 0.13%) and DALYs by 0.02 (95% CrI: 0.01, 0.03). Mean costs were higher with prenatal misoprostol distribution from governmental by US$3.3 (95% CrI: 2.1, 4.2) and modified societal (by US$1.3; 95% CrI: -1.6, 2.8) perspectives. ICERs were US$191 (95% CrI: 82, 443) per DALY averted from a governmental perspective, and US$73 (95% CI: -86, 256) per DALY averted from a modified societal perspective. Conclusions Prenatal distribution of misoprostol is potentially cost-effective in Uganda and should be

To compare sublingual misoprostol with intramuscular oxytocin for prevention of postpartum hemorrhage (PPH) in low-risk vaginal birth. In a prospective, randomized, double-blind trial, 530 women without risk of PPH were randomly allocated to receive either 400 μg of misoprostol sublingually or 10 units of oxytocin intramuscularly within 1minute of delivery. The outcome measures were incidence of PPH, postpartum blood loss, drop in hemoglobin level in 24 hours, need for additional uterotonic drug, incidence of adverse effects, and need for blood transfusion. Student t, χ(2), Mann-Whitney U, and Fisher exact tests were used for comparison. Incidence of postpartum hemorrhage (≥ 500 mL) and postpartum blood loss in the misoprostol group were similar to those in the oxytocin group (6% versus 5.7%, P=0.85; 153 mL versus 146 mL, P=0.36). Shivering and pyrexia were encountered more often in the misoprostol than in the oxytocin group (shivering: 19% versus 0.8%, P<0.001, relative risk [RR] 0.86, 95% confidence interval [CI] 0.82-0.90; pyrexia: 2.3% versus 0%, P=0.03, RR 0.97, 95% CI 0.95-0.99). The efficacy of 400 μg of misoprostol administered sublingually was equivalent to that of 10 units of oxytocin given intramuscularly for prevention of PPH in low-risk vaginal delivery.

MCG (Magnetocardiography) measurement by a SQUID gradiometer was attempted with only active magnetic shielding (active shielding). A three-axis-canceling-coil active shielding system, where three 16-10-16 turns-coil sets were put in the orthogonal directions, produces a homogeneous magnetic field in a considerable volume surrounding the center. Fluxgate sensors were used as the reference sensors of the system. The system can reduce environmental magnetic noise at low frequencies of less than a few Hz, at 50 Hz and at 150 Hz. Reducing such disturbances stabilizes biomagnetic measurement conditions for SQUIDs in the absence of magnetically shielded rooms (MSR). After filtering and averaging the measured MCG data by a first-order SQUID gradiometer with only the active shielding during the daytime, the QRS complex and T wave was clearly presented.

What is the efficacy of maintaining or restoring non-pregnant status with low-dose mifepristone combined with misoprostol administered before expected menstruation? Low-dose mifepristone and misoprostol administered at the time of expected menstruation was effective and safe in maintaining or restoring non-pregnant status, with no obvious menstrual disturbance. Menstrual regulation involves the medical or mechanical stimulation of uterine sloughing in women with up to 2-3 weeks of menstrual delay. Low-dose mifepristone plus misoprostol is efficacious for termination of ultra-early pregnancy (≤ 35 days of amenorrhoea) with no obvious menstrual disturbance. A total of 678 women fulfilled all criteria and were recruited. Seventeen women dropped out after deciding to remain pregnant and 11 others were lost to follow-up. Thus, data from 650 women who completed the procedure were included in analyses. Participants were enrolled at any time during their menstrual cycle and administered medication 1 day before expected menstruation. The end of the study was defined on a per-patient basis as the date of completion of the post-treatment menstrual cycle. The primary outcome was the efficacy of abortion induction (for pregnant women) or menstrual regulation (for non-pregnant women). Women with regular menstrual cycles (25-35 days) were voluntarily recruited for this study between February 2012 and December 2014. Serum β-hCG was measured before mifepristone intake. Mifepristone (50 mg) was administered orally 1 day before expected menstruation and 200 µg misoprostol was administered orally on the day of expected menstruation. Efficacy, disturbance in bleeding patterns in the treatment and post-treatment cycles, satisfaction with the treatment, and subsequent contraception preference were analysed. Retrospective analysis of serum β-hCG levels at admission indicated that 23.3% (158/678) of the women were pregnant. The success rate for pregnancy termination was 98.6% (136

A continuous regimen of oral levonorgestrel (LNG) 90 mcg/ethinyl estradiol (EE) 20 mcg was evaluated for inhibition of ovulation, time to return to ovulation after stopping treatment and safety. This open-label study was conducted in healthy women aged 18-35 years. Ovulation was documented before treatment, and then participants received oral tablets containing LNG 90 mcg/EE 20 mcg to be taken continuously for three 28-day intervals. Ovarian activity was assessed three times per week during the treatment period with transvaginal ultrasound scans and measurements of serum 17beta-estradiol, progesterone, follicle-stimulating hormone and luteinizing hormone concentrations. Safety assessments included physical examinations, laboratory evaluations and adverse event records. Thirty-seven of the 58 subjects who received treatment met predefined criteria for efficacy analysis. No on-treatment ovulations occurred in the efficacy or intent-to-treat population. There was evidence of ovulation within 37 days of stopping treatment for 46 (98%) of 47 subjects evaluated posttreatment. The final subject with a history of polycystic ovarian syndrome ovulated by Day 66. The safety profile observed during this 84-day continuous regimen was similar to that seen with other low-dose oral contraceptives administered in a cyclic regimen. The continuous LNG/EE regimen completely inhibited ovulation, with little evidence of follicular development and with rapid return of ovulatory capacity after stopping treatment.

Our purpose was to compare the efficacy and safety of misoprostol and extra-amniotic sodium chloride infusion with oxytocin for induction of labor. This randomized trial compared two methods of labor induction in women requiring cervical ripening. One hundred twenty-three women undergoing labor induction with a Bishop score < or =5 were randomly selected to receive either misoprostol, 50 microg intravaginally every 4 hours, or extra-amniotic sodium chloride infusion. The primary outcome variable was the time interval from induction to vaginal delivery. Sixty-one women received extra-amniotic sodium chloride infusion and 62 women received misoprostol. The mean time interval from the start of induction to vaginal delivery was 15.0 +/- 5.0 hours and 16.5 +/- 7.2 hours for the extra-amniotic infusion and misoprostol groups, respectively (P, not significant). The cesarean delivery rate was not significantly different between the 2 groups (32.8% for the extra-amniotic infusion group; 19.4% for the misoprostol group). Maternal and neonatal outcomes were similar between the 2 groups. Both methods of induction are equally efficacious and result in similar maternal and neonatal outcomes.

Although COX-2 inhibition in animal models of neurodegenerative diseases has shown neuroprotection, recent studies have revealed some serious side effects (ulcers, bleeding, fatal cerebrovascular diseases etc.) and the limited benefits of COX-2 inhibitors. A more focused approach is necessary to explore the therapeutic effect of the COX downstream signaling pathway in neurological research. The aim of this study was to explore the alterations of the PGES-PGE2-EP signal pathway and the effect of misoprostol on neurodegeneration by chronic aluminum-overload in rats. Adult rats were treated by intragastric administration of aluminum gluconate. The PGE2 content and expression of PGES and EPs in the hippocampi of rats were detected using ELISA, q-PCR and Western blot analysis, respectively. The content of malondialdehyde (MDA) and the activity of superoxide dismutase (SOD) in the rat hippocampi were also detected. The misoprostol treatment dose-dependently improved spatial learning and memory function as well as healing after hippocampal neuron damage induced by chronic aluminum-overload in rats. Meanwhile, the administration of misoprostol resulted in a decrease in the PGE2 level and down-regulation of the mPGES-1, EP2 and EP4 expression levels, while there was a dose-dependent up-regulation of EP3 expression. These results suggest that misoprostol possesses a neuroprotective property, and the mechanism involves affecting the EP3 level and reducing the endogenous production of PGE2 through a negative feedback mechanism, increasing the EP3 expression level, decreasing the EP2 and EP4 expression levels, and rebuilding the mPGES-1-PGE2-EP1-4 signal pathway balance. In this way, misoprostol has a counteractive effect on oxidant stress and inflammation in the central nervous system. The PGES-PGE2-EPs signaling pathway is a potential therapeutic strategy for treating neurodegeneration in patients. PMID:27033056

Concern has been raised that the risk of venous thromboembolism (VTE) in users of the ORTHO EVRA patch is higher compared to users of oral contraceptives (OCs). We identified idiopathic cases of VTE and controls, matched on age and index date, from among women in the United States PharMetrics/IMS and MarketScan databases who were current users of the patch or levonorgestrel-containing OCs with 30 mcg of ethinyl estradiol. We calculated odds ratios (ORs) and 95% confidence intervals (CIs). The ORs (95% CI) for VTE in users of the patch compared to levonorgestrel-containing OCs were 2.0 (0.9-4.1) and 1.3 (0.8-2.1) in the PharMetrics and MarketScan databases, respectively. ORs (95% CI) restricted to women aged 39 years or younger were 1.4 (0.6-3.0) and 1.2 (0.7-2.0), respectively. These results provide evidence that the risk of idiopathic VTE in users of the patch is not materially different than that of users of levonorgestrel-containing OCs in women aged 39 years or younger. We cannot rule out some increase in the risk in women aged 40 years or older.

The purpose of this study was to gather the necessary data to support the design and implementation of a pilot program for women who are unable to deliver in a healthcare facility in the Lao People's Democratic Republic (PDR), by using community distribution of misoprostol to prevent postpartum hemorrhage (PPH). The study builds on an earlier research that demonstrated both support and need for community-based distribution of misoprostol in Lao PDR. This qualitative study identified acceptability of misoprostol and healthcare system needs at varying levels to effectively distribute misoprostol to women with limited access to facility-based birthing. Interviews (n=25) were undertaken with stakeholders at the central, provincial, and district levels and with community members in five rural communities in Oudomxay, a province with high rates of maternal mortality. Focus group discussions (n=5) were undertaken in each community. Respondents agreed that PPH was the major cause of preventable maternal mortality with community distribution of misoprostol an acceptable and feasible interim preventative solution. Strong leadership, training, and community mobilization were identified as critical success factors. While several participants preferred midwives to distribute misoprostol, given the limited availability of midwives, there was a general agreement that village health workers or other lower level workers could safely administer misoprostol. Many key stakeholders, including women themselves, considered that these community-level staff may be able to provide misoprostol to women for self-administration, as long as appropriate education on its use was included. The collected data also helped identify appropriate educational messages and key indicators for monitoring and evaluation for a pilot program.

To evaluate whether a combination of misoprostol and oxytocin more effectively reduces blood loss during and after cesarean delivery than does oxytocin alone among women with known risk factors for postpartum hemorrhage (PPH). A prospective, randomized, double-blind, placebo-controlled trial was performed at a tertiary care center in Kolkata, India, between October 2012 and December 2013. Women were eligible if they were undergoing emergency cesarean under spinal anesthesia and were at high risk for PPH. Participants were randomly assigned (1:1) to receive 400 μg misoprostol or matched placebo sublingually after delivery of the newborn using a computer-generated random number sequence (block size eight). Participants and providers were masked to assignment. All participants received 20 IU oxytocin. The primary outcomes were intraoperative and postoperative blood loss. Both groups contained 198 women. Mean intraoperative blood loss was significantly lower in the misoprostol group (505.4±215.5 mL) than in the placebo group (587.3±201.5 mL; P<0.001). Mean postoperative blood loss was slightly lower in the misoprostol group (96.9±57.3 mL) than in the placebo group (103.4±58.4 mL; P=0.07). Shivering and pyrexia were more frequently associated with misoprostol (P<0.05 for both). Misoprostol as an adjunct to oxytocin seemed to more effectively reduce blood loss than did oxytocin alone.

Seven paediatric patients with central diabetes insipidus were studied in an open dose ranging study in hospital followed by a six month study on an outpatient basis to assess the efficacy and safety of peroral administration of DDAVP (desmopressin) tablets. In the dose ranging study a dose dependent antidiuretic response was observed. The response to 12.5-50 mcg was, however, less effective in correcting baseline polyuria than were doses of 100 mcg and above. Patients were discharged from hospital on a preliminary dosage regimen ranging from 100 to 400 mcg three times daily. After an initial adjustment in dosage in three patients at one week follow up, all patients were stabilised on treatment with tablets and reported an adequate water turnover at six months. As with the intranasal route of administration dosage requirements varied from patient to patient, and a dose range rather than standard doses were required. A significant correlation, however, was found for the relation between previous intranasal and present oral daily dosage. No adverse reactions were reported. No clinically significant changes were noted in blood chemistry and urinalysis. All patients expressed a preference for the oral over existing intranasal treatment. Treatment with tablets offers a beneficial alternative to the intranasal route, particularly in patients with chronic rhinitis or impaired vision. PMID:3963868

Civil Society Organizations and medicines policy change: a case study of registration, procurement, distribution and use of misoprostol in Uganda.

Misoprostol use for postpartum haemorrhage (PPH) has been promoted by Civil Society Organizations (CSOs) since the early 2000s. Yet, CSOs' role in improving access to misoprostol and shaping health policy at global and national levels is not well understood. We document the introduction of misoprostol in Uganda in 2008 from its registration, addition to treatment guidelines and national Essential Medicines List (EML), to its distribution and use. We then analyse the contribution of CSOs to this health policy change and service provision. Policy documents, procurement data and 82 key informant interviews with government officials, healthcare providers, and CSOs in four Ugandan districts of Kampala, Mbarara, Apac, Bundibugyo were collected between 2010 and 2013. Five key CSOs promoted and accelerated the rollout of misoprostol in Uganda. They supported the registration of misoprostol with the National Drug Authority, the development of clinical guidelines, and the piloting and training of health care providers. CSOs and National Medical Stores were procuring and distributing misoprostol country-wide to health centres two years before it was added to the clinical guidelines and EML of Uganda and in the absence of good evidence. The evidence suggests an increasing trend of misoprostol procurement and availability over the medicine of choice, oxytocin. This shift in national priorities has serious ramifications for maternal health care that need urgent evaluation. The absence of clinical guidelines in health centres and the lack of training preclude rational use of misoprostol. CSOs shifted their focus from the public to the private sector, where some of them continue to promote its use for off-label indications including induction of labour and abortion. There is an urgent need to build capacity to improve the robustness of the national and local institutions in assessing the safety and effectiveness of all medicines and their indications in Uganda.

Discussion of Source Reconstruction Models Using 3D MCG Data

NASA Astrophysics Data System (ADS)

Melis, Massimo De; Uchikawa, Yoshinori

In this study we performed the source reconstruction of magnetocardiographic signals generated by the human heart activity to localize the site of origin of the heart activation. The localizations were performed in a four compartment model of the human volume conductor. The analyses were conducted on normal subjects and on a subject affected by the Wolff-Parkinson-White syndrome. Different models of the source activation were used to evaluate whether a general model of the current source can be applied in the study of the cardiac inverse problem. The data analyses were repeated using normal and vector component data of the MCG. The results show that a distributed source model has the better accuracy in performing the source reconstructions, and that 3D MCG data allow finding smaller differences between the different source models.

Misoprostol management of miscarriage is only now becoming widely used in Australia. To review the efficacy, safety and the popularity of outpatient sublingual misoprostol in empty sac/missed miscarriage management over its first two years of availability in a metropolitan Australian hospital. A retrospective cohort review was undertaken of women choosing sublingual misoprostol 600 μg (three tablets) × three doses for miscarriage management. Principal outcomes assessed were miscarriage resolution without the need for curettage and complications. Additionally, the relative popularity of misoprostol versus surgery by place of birth and over time, and the return of pregnancy tissue for histology were analysed. Between 1 December 2012 and 30 November 2014, 279 women chose sublingual misoprostol for nonurgent miscarriage management, while 420 chose surgery (40 and 60%, respectively). Of the misoprostol cohort, 269 had complete data; 239 of 269 (88.8%) had resolution without curettage, nine (3.3%) had acute curettage, 21 (7.8%) had nonacute curettage, 30 (11.15%) had unplanned emergency department presentation, 11 (4.1%) had unplanned admission, three (1.1%) had blood transfusion and one (0.4%) had an infection requiring admission. Misoprostol was as popular with Australian-born as overseas-born women; 53.5% of patients returned histopathology specimens; one (0.7%) demonstrated partial hydatidiform mole. Outpatient management of missed/empty gestational sac miscarriage using sublingual misoprostol is associated with a high rate of avoiding curettage and the low rate of complication. It is equally popular with Australian-born and overseas-born women. Just over 50% returned pregnancy tissue for analysis. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

The objective of this study is to compare the uterine activity response between women administered dinoprostone (prostaglandin E2) and misoprostol (prostaglandin E1) for induction of labour (IOL) by analysing not only the traditional obstetric data but also the parameters extracted from uterine electrohysterogram (EHG). Two cohorts were defined: misoprostol (25-µg vaginal tablets; 251 women) and dinoprostone cohort (10 mg vaginal inserts; 249 women). All the mothers were induced by a medical indication of a Bishop Score < = 6. The misoprostol cohort was associated with a shorter time to achieve active labour (p = .017) and vaginal delivery (p = .009) and with a higher percentage of vaginal delivery in less than 24 h in mothers with a very unfavourable cervix score (risk ratio (RR): 1.41, IC95% 1.17-1.69, p = .002). Successful inductions with misoprostol showed EHG parameter values significantly higher than basal state for amplitude and pseudo Montevideo units (PMU) 60' after drug administration, while spectral parameters significantly increased after 150'. This response was not observed in failed inductions. In the successful dinoprostone group, the duration and number of contractions increased significantly after 120', PMU did so after 180', and no significant differences were found for spectral parameters, possibly due to the slower pharmacokinetics of this drug. Successful inductions of labour by misoprostol are associated with earlier effective contractions than in labours induced by dinoprostone.

Several radioligands targeting prostate-specific membrane antigen (PSMA) have been clinically introduced as a new class of radiotheranostics for the treatment of prostate cancer. Among them, ((( R)-1-carboxy-2-mcercaptoethyl)carbamoyl)-l-glutamic acid (MCG) has been successfully labeled with radioisotopes for prostate cancer imaging. The aim of this study is to conjugate MCG with an albumin binding moiety to further improve the in vivo pharmacokinetics. MCG was conjugated with an Evans blue (EB) derivative for albumin binding and a DOTA chelator. PSMA positive (PC3-PIP) and PSMA negative (PC3) cells were used for both in vitro and in vivo studies. Longitudinal PET imaging was performed at 1, 4, 24, and 48 h post-injection to evaluate the biodistribution and tumor uptake of 86 Y-DOTA-EB-MCG. DOTA-EB-MCG was also labeled with 90 Y for radionuclide therapy. Besides tumor growth measurement, tumor response to escalating therapeutic doses were also evaluated by immunohistochemistry and fluorescence microscopy. Based on quantification from 86 Y-DOTA-EB-MCG PET images, the tracer uptake in PC3-PIP tumors increased from 22.33 ± 2.39%ID/g at 1 h post-injection (p.i.), to the peak of 40.40 ± 4.79%ID/g at 24 h p.i. Administration of 7.4 MBq of 90 Y-DOTA-EB-MCG resulted in significant regression of tumor growth in PSMA positive xenografts. No apparent toxicity or body weight loss was observed in all treated mice. Modification of MCG with an Evans blue derivative resulted in a highly efficient prostate cancer targeting agent (EB-MCG), which showed great potential in prostate cancer treatment after being labeled with therapeutic radioisotopes.

To examine the use of mifepristone and misoprostol for menstrual regulation among Bangladeshi women attending public sector facilities. In a prospective study, women (aged ≥18 years) with up to 9 weeks of amenorrhea were enrolled at 24 government health facilities in Bangladesh from November 2012 to June 2015. Paramedics or female welfare visitors provided most menstrual regulation care. Participants took 200 mg mifepristone followed by 800 μg buccal misoprostol after 24 hours, and were asked to return to the clinic 10-14 days later for clinical assessment and an exit interview. The primary outcome was successful evacuation of the uterus without need for surgical intervention. Women who completed follow-up were included in analyses for the primary outcome. Among 1744 enrolled participants, 1738 completed follow-up. Most (1674, 96.3%) had a successful uterine evacuation without the need for surgical intervention. A successful outcome was significantly more common in primary (724/744, 97.3%) and secondary facilities (861/895, 96.2%) than in the specialty hospital (89/99, 89.9%; P<0.001 and P=0.004, respectively). Menstrual regulation with mifepristone and misoprostol can be provided effectively in public sector facilities in Bangladesh.

To evaluate the experience of women receiving mifepristone-misoprostol for early induced abortion in public sector facilities in the Federal District of Mexico City. An open-label prospective study was conducted with 1000 pregnant women who sought induced abortion with a pregnancy of up to 63days of gestation, as measured from the date of their last menstrual period. The study was conducted in three public sector healthcare facilities: two secondary level hospitals and one primary care clinic. Women ingested 200mg mifepristone on day 1, followed by 800μg buccal misoprostol 24hours later, and they returned for follow-up on day 8. The primary outcome was complete abortion without recourse to surgical intervention. A total of 971 women received mifepristone-misoprostol and were included in the analysis for efficacy of treatment. The overall efficacy of the combined medical abortion regimen studied was 97.3% (n=945); the success rate did not vary significantly by gestational age (95.9%-100%; P=0.449). Most women (n=922, 95.0%) had a successful induced abortion with only one dose of misoprostol. The combined mifepristone and buccal misoprostol regimen was found to be highly effective and acceptable among Mexican women. www.ClinicalTrials.gov: NCT00386282.

To determine the efficacy of the prostaglandin E1 analogue misoprostol in the treatment of tinnitus in diabetic and/or hypertensive patients. Double-blind, randomized, placebo-controlled trial. Tertiary care referral center. The subjects were 42 patients with hypertension and/or diabetes mellitus who had chronic tinnitus and had experienced tinnitus symptoms for a minimum of 6 months. Twenty-eight patients were randomly assigned to Group I (misoprostol treatment), and 14 patients to the Group II (placebo treatment). Misoprostol therapy was started at 200 microg per day, and was increased 200 microg every 7 days until a dose of 800 microg per day was reached. The same numbers of placebo tablets were given to the control group using the same schedule. Both groups were treated for 1 month. The changes in objective and subjective tinnitus findings from baseline to 1 month were assessed, and the group results were compared. The chi(2)-test, student's t-test and paired-samples t-test were used to analyze the study. At the completion of treatment, objective assessment showed that tinnitus loudness decreased in 13 (46%) of the 28 patients in the experimental group, whereas this was observed in only two (14%) of the 14 subjects in the placebo group. Subjective tinnitus scoring revealed improvement rates of 29 and 14% for the misoprostol and placebo groups, respectively. When t-test relating to difference between rates were performed, the difference between improvement rate for tinnitus loudness of the experimental group and control group was found to be statistically significant (P = 0.05), but difference between improvement rate based on subjective tinnitus scoring was insignificant (P = 0.22). Misoprostol is an effective and safe treatment for chronic tinnitus in hypertensive and/or diabetic patients. Our results are encouraging, but further studies of larger series are needed.

Misoprostol is reported to prevent non-steroidal anti-inflammatory drug (NSAID)-associated gastroduodenal complications. There is, however, limited information regarding the efficacy of DA-9601 in this context. We performed a comparative study on the relative efficacy of DA-9601 and misoprostol for prevention of NSAID-associated complications. In this multicenter, double-blinded, active-controlled, stratified randomized, parallel group, non-inferiority trial, 520 patients who were to be treated with an NSAID (aceclofenac, 100 mg, twice daily) over a 4-week period were randomly assigned to groups for coincidental treatment with DA-9601 (60 mg, thrice daily) (236 patients for full analysis) or misoprostol (200 μg, thrice daily) (242 patients for full analysis). [corrected]. The primary endpoint was the gastric protection rate, and secondary endpoints were the duodenal protection rate and ulcer incidence rate. Endpoints were assessed by endoscopy after the 4-week treatment period. Drug-related adverse effects, including gastrointestinal (GI) symptoms, were also compared. At week 4, the gastric protection rates with DA-9601 and misoprostol were 81.4 % (192/236) and 89.3 % (216/242), respectively. The difference between the groups was -14.2 %, indicating non-inferiority of DA-9601 to misoprostol. Adverse event rates were not different between the two groups; however, the total scores for GI symptoms before and after administration were significantly lower in the DA-9601 group than in the misoprostol group (-0.2 ± 2.8 vs 1.2 ± 3.2; p < 0.0001). DA-9601 is as effective as misoprostol in preventing NSAID-associated gastroduodenal complications, and has a superior adverse GI effect profile.

Afghanistan has a maternal mortality ratio of 400 per 100,000 live births. Hemorrhage is the leading cause of maternal death. Two-thirds of births occur at home. A pilot program conducted from 2005 to 2007 demonstrated the effectiveness of using community health workers for advance distribution of misoprostol to pregnant women for self-administration immediately following birth to prevent postpartum hemorrhage. The Ministry of Public Health requested an expansion of the pilot to study implementation on a larger scale before adopting the intervention as national policy. The purpose of this before-and-after study was to determine the effectiveness of advance distribution of misoprostol for self-administration across 20 districts in Afghanistan and identify any adverse events that occurred during expansion. Cross-sectional household surveys were conducted pre- (n = 408) and postintervention (n = 408) to assess the effect of the program on uterotonic use among women who had recently given birth. Maternal death audits and verbal autopsies were conducted to investigate peripartum maternal deaths that occurred during implementation in the 20 districts. Uterotonic use among women in the sample increased from 50.3% preintervention to 74.3% postintervention. Because of a large-scale investment in Afghanistan in training and deployment of community midwives, it was assumed that all women who gave birth in facilities received a uterotonic. A significant difference in uterotonic use at home births was observed among women who lived farthest from a health facility (> 90 minutes self-reported travel time) compared to women who lived closer (88.5% vs 38.9%; P < .0001). All women who accepted misoprostol and gave birth at home used the drug. No maternal deaths were identified among those women who used misoprostol. The results of this study build on the findings of the pilot program and provide evidence on the effectiveness, primarily measured by uterotonic use, of an expansion of

Fetal magnetocardiography (fMCG) is a noninvasive technique suitable for the prenatal diagnosis of the fetal heart function. Reliable fetal cardiac signals can be reconstructed from multi-channel fMCG recordings by means of independent component analysis (ICA). However, the identification of the separated components is usually accomplished by visual inspection. This paper discusses a novel automated system based on entropy estimators, namely approximate entropy (ApEn) and sample entropy (SampEn), for the classification of independent components (ICs). The system was validated on 40 fMCG datasets of normal fetuses with the gestational age ranging from 22 to 37 weeks. Both ApEn and SampEn were able to measure the stability and predictability of the physiological signals separated with ICA, and the entropy values of the three categories were significantly different at p <0.01. The system performances were compared with those of a method based on the analysis of the time and frequency content of the components. The outcomes of this study showed a superior performance of the entropy-based system, in particular for early gestation, with an overall ICs detection rate of 98.75% and 97.92% for ApEn and SampEn respectively, as against a value of 94.50% obtained with the time-frequency-based system.

Most studies on the use of misoprostol for induction of labour have been carried out in well-endowed hospitals in developed countries with state-of-the-art monitoring equipment. There is need for more studies to be conducted in facilities with limited resources, if more patients are to benefit from the low cost and effectiveness of the drug. Following Ethical Committee approval, 152 women had labour induced in our maternity unit using intravaginal misoprostol. The patients were monitored clinically using the WHO model partograph with digital palpation of uterine contractions and intermittent auscultation of fetal heart with a pinard stethoscope. One hundred and thirty-five (88.8%) of the women had a vaginal delivery, while nine (5.9%) had a caesarean section for various obstetric indications. Eight cases of uterine hyperstimulation were noted but none of uterine rupture. We conclude that misoprostol can be used safely for induction of labour in less endowed hospital settings such as in developing countries, using basic clinical tools for monitoring.

A novel misoprostol delivery system for induction of labor: clinical utility and patient considerations.

Stephenson, Megan L; Wing, Deborah A

Induction of labor is one of the most commonly performed obstetric procedures and will likely become more common as the reproductive population in developed nations changes. As the proportion of women undergoing induction grows, there is a constant search for more efficacious ways to induce labor while maintaining fetal and maternal safety as well as patient satisfaction. With almost half of induced labors requiring cervical ripening, methods for achieving active labor and vaginal delivery are constantly being investigated. Prostaglandins have been shown to be effective induction agents, and specifically vaginal misoprostol, used off-label, have been widely utilized to initiate cervical ripening and active labor. The challenge is to administer this medication accurately while maintaining the ability to discontinue the medication when needed. The misoprostol vaginal insert initiates cervical ripening utilizing a delivery system that controls medication release and can be rapidly removed. This paper reviews the design, development, and clinical utility of the misoprostol vaginal insert for induction of labor as well as patient considerations related to the delivery system.

Etude prospective réalisée au service de gynécologie obstétrique B de l'hôpital Charles Nicolle de Tunis sur une durée de 4 mois. La population sélectionnée concernait les patientes à terme devant bénéficier d'une maturation cervicale. Le misoprostol à la dose de 50 µg par voie vaginale toutes les 12 h était utilisé. Les paramètres étudiés étaient les anomalies contractiles, les anomalies du RCF, le mode d'accouchement, le délai d'accouchement et l’état néonatal. 44 patientes ont bénéficié d'une maturation cervicale par misoprostol. Le terme moyen était de 40 SA. Le taux de nullipare était de 23/44 (52%). Le taux d'accouchement par voie basse était de 31/44 (70.4%). 84% des patientes ont reçu une seule dose de misoprostol. Les anomalies du RCF ont été notées dans 14/44 (32%). Le taux de liquides méconiaux était de 12/44 (27%). Un score d'Apgar à 5 mn inférieur à 7 était noté chez 7/44 (16%). Un cas de rupture utérine était survenue chez une primipare et ce après une seule prise de misoprostol. Nos résultats sont décevants en raison de la survenue d'une rupture utérine et d'une morbidité néonatale importante. D'autres études prospectives multicentriques restent utiles pour mieux s'assurer de l'efficacité mais surtout de l'innocuité du misoprostol à dose faible pour le déclenchement du travail à terme.

To determine whether buccal misoprostol during cesarean delivery in conjunction with active management of the third stage of labor reduces the need for additional uterotonic drugs. A double-blind, randomized, placebo-controlled trial was performed in Monterrey, Mexico, between February 2008 and December 2013. Eligible women had risk factors for uterine atony and were to undergo cesarean delivery under epidural block. Using a computer-generated sequence and blocks of six, patients were randomly assigned to receive 400μg misoprostol or 800μg placebo buccally after cord clamping. Both groups received an intravenous oxytocin infusion. The primary outcome was the need for additional uterotonic drugs. Analyses were performed per protocol. Patients, investigators, and data analysts were masked to group assignment. A total of 120 women were included in analyses (60 in each group). At least one additional uterotonic drug was required in 24 (40%) women in the placebo group versus 6 (10%) women in the misoprostol group (relative risk 0.16; 95% confidence interval 0.06-0.44). No adverse effects due to misoprostol were recorded. Buccal misoprostol during cesarean delivery reduced the need for additional uterotonic drugs to treat uterine atony.

Purpose: Acute radiation proctitis is the most relevant complication of pelvic radiation and is still mainly treated supportively. Considering the negative impact of acute proctitis symptoms on patients' daily activities and the potential relationship between the severity of acute radiation injury and late damage, misoprostol was tested in the prevention of acute radiation-induced proctitis. Methods and Materials: A total of 100 patients who underwent radiotherapy for prostate cancer were entered into this phase III randomized, placebo-controlled, double-blind study with misoprostol or placebo suppositories. Radiation-induced toxicity was evaluated weekly during radiotherapy using the Common Toxicity Criteria. Results: Between the placebo andmore » the misoprostol groups, no significant differences in proctitis symptoms occurred: 76% of patients in each group had Grade 1 toxicity, and 26% in the placebo group and 36% in the misoprostol group had Grade 2 toxicity. No differences were found in onset or symptom duration. Comparing the peak incidence of patients' toxicity symptoms, significantly more patients experienced rectal bleeding in the misoprostol group (p = 0.03). Conclusion: Misoprostol given as a once-daily suppository did not decrease the incidence and severity of radiation-induced acute proctitis and may increase the incidence of acute bleeding.« less

Although medical abortion with home use of misoprostol has been shown to be safe and acceptable, there are few data about the experience of pain during the procedure. The aims of this study were to assess the intensity of pain associated with home use of misoprostol for medical abortion and to identify variables associated with severe pain. This was an observational study using an anonymous web-based questionnaire in patients having a medical abortion at home in France between 1 December 2013 and 30 April 2014. The questionnaire was completed by 232 women and the results of 193 were retained for analysis. The average pain score was 5.6 on a 10 point scale. A pain score ≥6 was rated as severe and was reported by 105 patients (54%). Nulliparity (odds ratio [OR] 4.10; 95% confidence interval [CI] 2.04, 8.22; p < .0001), lack of choice regarding the method of abortion (OR 2.32; 95% CI 1.13, 4.78; p = .0218) and lack of information about the level of pain associated with the procedure (OR 3.27; 95% CI 1.09, 9.74; p = .0334) were significantly correlated with severe pain. Analgesic prescriptions were very heterogeneous. Pain remains the main side effect of medical abortion. More studies are needed on pain assessment and the effectiveness of analgesic treatments in women using misoprostol at home for medical abortion, in order to improve their care and improve evidence-based guidelines.

The optimal dose of misoprostol for the induction of labour remains uncertain. To compare the efficacy and safety of 25 versus 50 micrograms of intravaginal misoprostol tablets for the induction of labour and cervical ripening. We performed electronic and manual searches to identify relevant randomised trials. The efficacy outcomes assessed were rates of vaginal delivery within 24 hours, delivery within one dose, and oxytocin augmentation, and interval to delivery. The safety outcomes assessed were incidences of tachysystole, hyperstimulation, caesarean delivery, cesarean delivery for non-reassuring fetal heart rate (FHR), operative vaginal delivery, abnormal 5-minute Apgar score, abnormal cord gas values, admission to a neonatal intensive care unit (NICU), and meconium passage. Thirteen studies (1945 women) were included. Relative risk (RR) and 95% confidence intervals (CI) were calculated using fixed-effects and random-effects models. We found that 25 micrograms was less efficacious, with lower rates of delivery after one dose (RR 0.59; 95% CI 0.39-0.88) and vaginal delivery within 24 hours (RR 0.88; 95% CI 0.79-0.96), and with increased rates of oxytocin augmentation (RR 1.54, 95% CI 1.36-1.75). We noted an improved safety profile with 25 micrograms, however, with decreased rates of tachysystole (RR 0.46; 95% CI 0.35-0.61), hyperstimulation (RR 0.5; 95% CI 0.31-0.78), caesarean deliveries for non-reassuring FHR (RR 0.67; 95% CI 0.52-0.87), NICU admissions (RR 0.63; 95% CI 0.4-0.98), and meconium passage (RR 0.65; 95% CI 0.45-0.96). Although 50 micrograms of intravaginal misoprostol may be more efficacious, safety concerns make the 25-microgram dose preferable. © 2014 Royal College of Obstetricians and Gynaecologists.

Retained placenta is one of the common causes of maternal mortality in developing countries where access to appropriate obstetrical care is limited. Current treatment of retained placenta is manual removal of the placenta under anaesthesia, which can only take place in larger health care facilities. Medical treatment of retained placenta with prostaglandins E1 (misoprostol) could be cost-effective and easy-to-use and could be a life-saving option in many low-resource settings. The aim of this study is to assess the efficacy and safety of sublingually administered misoprostol in women with retained placenta in a low resource setting. Multicentered randomised, double-blind, placebo-controlled trial, to be conducted in 5 hospitals in Tanzania, Africa. Women with retained placenta, at a gestational age of 28 weeks or more and blood loss less than 750 ml, 30 minutes after delivery of the newborn despite active management of third stage of labour. Trial Entry & Randomisation & Study Medication: After obtaining informed consent, eligible women will be allocated randomly to the treatment groups using numbered envelopes that will be randomized in variable blocks containing identical capsules with either 800 microgram of misoprostol or placebo. The drugs will be given sublingually. The women, maternal care providers and researchers will be blinded to treatment allocation. 117 women, to show a 40% reduction in manual removals of the placenta (p = 0.05, 80% power). The randomization will be misoprostol: placebo = 2:1. PRIMARY STUDY OUTCOME: Expulsion of the placenta without manual removal. Secondary outcome is the number of blood transfusions. This is a protocol for a randomized trial in a low resource setting to assess if medical treatment of women with retained placenta with misoprostol reduces the incidence of manual removal of the placenta.

Amphetamine and methamphetamine are popular drugs of abuse worldwide and are important components of drug monitoring programs. Windows of detection for amphetamine and methamphetamine in oral fluid after high doses have not been investigated. Repeated high-dose ingestions are likely to cause positive samples for extended periods. Common routes of administration of amphetamine/methamphetamine in Norway are oral intake or injection. The aim of this study was to investigate windows of detection for amphetamine and methamphetamine in oral fluid from drug addicts under sustained abstinence during detoxification. Twenty-five patients admitted to a closed detoxification unit were included in this study. Oral fluid samples were collected daily in the morning and evening, and urine every morning for 10 days. A blood sample was drawn during the first 5 days after admission if the patient consented. Oral fluid results were compared with urine results to determine whether a new ingestion occurred. Oral fluid was collected with the Intercept oral fluid collection device. In-house cutoff concentrations for amphetamine and methamphetamine were 6.8 and 7.5 mcg/L, respectively, in oral fluid, and 135 and 149 mcg/L, respectively, in urine. Amphetamines were detected in 11 oral fluid, 5 urine, and 2 blood specimens from 25 patients. Patients self-reported amphetamines intake of up to 0.5-2 g daily. Windows of detection for amphetamine and methamphetamine in oral fluid were up to 8 days, longer than in urine at the applied cutoff values. These data confirm that oral fluid is a viable alternative to urine for monitoring amphetamine abuse, and that these substances might be detected in oral fluid for at least 1 week after ingestion of high doses. Such long detection times were, as far as we are aware, never reported previously for oral fluid amphetamines.

Stability of nitroglycerin 110 mcg/mL stored in polypropylene syringes.

Various angiography procedures at Mayo Clinic (Rochester campus) require small bolus doses of injectable nitroglycerin. Commercially acquired containers of injectable nitroglycerin provide excessive amounts of drug for these procedural needs, so syringes were chosen as a container for dispensing of the dose needed. Due to nitroglycerin's known chemical attributes of volatility and sorption to plastic surfaces, careful consideration of the stability needs to be taken into account when storing in a syringe. Since there is a lack of stability information in the literature, we studied the stability of nitroglycerin in polypropylene syringes over 90 days. Methods used for this study consisted of a validated stability-indicating high-performance liquid chromatographic assay, visual appearance, and pH. Samples were stored protected from light at ambient controlled temperature and consisted of nitroglycerin 110 mcg/mL in 5% dextrose injection 10.1 mL in 12 mL Terumo polypropylene syringes. Samples were tested at intervals up to 90 days. Results from the visual portion of the study showed clear, colorless, and particulate-free solutions throughout the 90-day study period. The pH results started at 4.27 +/- 0.13 (day 0) and ranged from 4.19 +/- 0.17 to 4.92 +/- 0.43 throughout the study period. Potency test results revealed a day 0 concentration of 104.242 +/- 0.193 mcg/mL (batch 1) and 122.483 +/- 0.168 mcg/mL (batch 2). Results trended downward with percentage of day 0 concentration of 92.2% +/- 2.4% at day 14 and of 81.4% +/- 4.9% at day 90. Chromatographic profiles of the samples exhibited insignificant changes over the study period. The nitroglycerin peak was spectrally pure based on peak-purity analysis, suggesting that sorption to the polypropylene syringe is one possible reason for the concentration decline over time, but nitroglycerin is a volatile compound and loss through vaporization cannot be ruled out.

This randomized study's aim was to compare the effect of four oral contraceptives (OCs) containing 30 mcg of ethinylestradiol (EE) and different progestogens [drospirenone, (DRSP), chlormadinone acetate (CMA), desogestrel (DSG), gestodene (GSD)] on biochemical and hormonal parameters of hyperandrogenism and sex hormone-binding globulin (SHBG) in women with polycystic ovary syndrome (PCOS). Forty women with PCOS (age 16-35 years) were recruited and randomly assigned to one of four treatment groups of 10 women each, treated, respectively, with 3 mg DRSP/30 mcg EE (Yasmin, Bayer Shering), 2 mg CMA/30 mcg EE (Belara, Grunenthal), 75 mcg GSD/30 mcg EE (Minulet, Wyeth Lederle) and 150 mcg DSG/30 mcg EE (Practil 21, Organon Italia). Blood samples were obtained on day 6-8 of the control cycle and day 6-8 of the third treatment cycle for assay of the following hormones: androsteredione (A), total testosterone (T), free T, SHBG, dehydroepiandrosterone sulphate (DHEAS). In all groups, mean concentrations of free T, total T and A dropped by 40-60%, and concentrations of DHEAS dropped by 20-50%. Formulations with DRSP and CMA caused a greater reduction of androgens and a progressive increase in serum concentrations of SHBG than those with DSG and GSD. Clinical studies need to be performed to determine effects of these OCs upon clinical signs of hyperandrogenism. Copyright 2010 Elsevier Inc. All rights reserved.

Although the use of continuous oral contraceptive pills (OCPs) eliminates scheduled uterine bleeding, unscheduled bleeding is common. The objective of this study was to determine whether progestin dose influences bleeding with use of continuous OCPs. This was a secondary data analysis of two other studies of continuous OCPs. Women were eligible if they were switching from a cyclic hormonal contraceptive to a continuous OCP. Women took a 20-mcg ethinyl estradiol (EE)/100-mcg levonorgestrel (LNG) pill or a 20-mcg EE/90-mcg LNG pill for 112 days. The number of bleeding/spotting days was compared between groups using a t test. Sample size was adequate to detect a difference of 8 days of bleeding/spotting over the 112 day study period (β=0.80, α=0.05). Sixty-six subjects were enrolled, 33 in each group. There were no differences in baseline characteristic, missed OCPs or side effects. There were no differences in the mean number of bleeding/spotting days in the first 84 days of the study (90 mcg LNG mean 20.8 (SE 3.6) days versus 100 mcg LNG 17.8 (SE 2.3) days, p=.48), nor was there a difference in the time to amenorrhea (p=.35). Our results do not support the use of one LNG dose over another to decrease the amount of unscheduled bleeding women experience when initiating a continuous OCP. Copyright © 2012 Elsevier Inc.

Bleeding from gastroduodenal lesions is a potentially life-threatening complication in patients subjected to overwhelming physiologic stress. Titration of gastric contents with antacid was the first prophylactic treatment regimen proved to decrease the incidence of bleeding and remains the standard by which other methods are compared. We designed a prospective double-blind, double-placebo study comparing the effectiveness of antacid titration with fixed doses of a synthetic prostaglandin E1 analog (misoprostol) for preventing stress gastritis and bleeding. To assess the success of each treatment regimen, we did endoscopic examinations before operation, 72 hours after operation, and after the patient had completed the study. A total of 281 patients entered the study (140 misoprostol, 141 antacid). The two groups were comparable with respect to preoperative parameters and type of operation. We found no statistically significant differences between the two treatment groups concerning upper gastrointestinal tract lesions or serious adverse effects. No clinically evident upper gastrointestinal hemorrhage occurred in either group. Mean gastric pH, measured at two-hour intervals during the initial 72 hours, was maintained at 4.0 or higher in both groups. We conclude that fixed-dose misoprostol is as effective as intensive antacid titration in preventing stress ulcers and bleeding in surgical ICU patients. PMID:2510618

By studying the chaos attractor of cardiac magnetic induction strength B(z) generated by the electrical activity of the heart, we found that its projection in the reconstructed phase space has a similar shape with the map of the total current dipole vector. It is worth noting that the map of the total current dipole vector is computed with MCG recordings measured at 36 locations, whereas the chaos attractor of B(z) is generated by only one cardiac magnetic field recordings on the measured plan. We discuss only two subjects of different ages in this paper.

To evaluate the efficacy and safety of misoprostol among patients with retained placenta in a low-resource setting. A prospective, multicenter, randomized, double-blind, placebo-controlled trial was carried out in Tanzania between April 2008 and November 2011. It included patients who delivered at a gestational age of 28 weeks or more and had blood loss of 750 mL or less at 30 minutes after delivery. Sublingual misoprostol (800 μg) was compared with placebo as the primary treatment. Power analysis showed that 117 patients would be required to observe a reduction of 40% in the incidence of manual removal of the placenta (MRP; P=0.05, 80% power), the primary outcome. The secondary outcomes were blood loss and number of blood transfusions. Interim analysis after recruitment of 95 patients showed that incidence of MRP, total blood loss, and incidence of blood transfusions were similar in the misoprostol (MRP, 40%; blood loss, 803 mL; blood transfusion, 15%) and placebo (MRP, 33%, blood loss 787 mL, blood transfusion, 23%) groups. The trial was stopped because continuation would not alter the interim conclusion that misoprostol was ineffective. Treatment with misoprostol was found to have no clinically significant beneficial effect among women with retained placenta. Current Controlled Trials ISRCTN16104753.

[The illegal market for gender-related drugs as portrayed in the Brazilian news media: the case of misoprostol and women].

This article analyzes how the Brazilian news media covers the illegal market for misoprostol, the main drug used to induce abortion. A total of 1,429 news stories were retrieved from 220 print and electronic media channels from 2004 to 2009. The analysis included 524 stories from 62 regional and national newspapers. Misoprostol appeared repeatedly in the news, but was usually approached from a criminal perspective, unlike abortion as a whole, which the Brazilian media routinely covers as a religious, political, and public health issue. Misoprostol is part of the illegal gender-related drug market, along with drugs for weight loss and erectile dysfunction and anabolic steroids. Sixty-four (12%) of the news stories told life histories of women who had aborted with misoprostol. The women's ages ranged from 13 to 46 years, and socioeconomic status was associated with different experiences with abortion. Three characters appeared in the women's abortion itineraries: girlfriends (confidantes), go-betweens, and physicians. Stories of late-stage abortion are confused with the criminal characterization of infanticide and provide the extreme cases in the media's narrative on abortion.

This study was conducted to determine if oral triiodothyronine supplementation could prevent the decrease of serum triiodothyronine levels that commonly occurs after cardiopulmonary bypass for pediatric congenital heart surgery. Secondary objectives included identifying any significant adverse effects of oral triiodothyronine supplementation, including any effects on the thyroid/pituitary axis. Randomized, placebo-controlled, doubleblind clinical trial Operating room and ICU. Infants and children younger than 2 years of age undergoing congenital heart surgery using cardiopulmonary bypass (n = 43). Subjects were assigned to placebo (n = 15, group A) or one of two treatment groups: a low-dose group (group B, n = 14, 0.5 mcg/kg triiodothyronine orally every 24 hr for 3 d) or a high-dose group (group C, n = 14, 0.5 mcg/kg triiodothyronine orally every 12 hr for 3 d). Thyroid hormone, including total and free triiodothyronine levels at predetermined time points, potential side effects indicating hyperthyroidism, indicators of the thyroid-pituitary axis, and clinical endpoints. Oral triiodothyronine supplementation twice-daily maintained serum triiodothyronine levels within normal limits in group C, whereas serum levels progressively declined in groups A and B. A statistically significant difference in triiodothyronine levels between the treatment groups occurred between 18 and 36 hours post cross-clamp release, with the largest difference in serum levels between group C and group A noted at 36 hours post cross-clamp release (total triiodothyronine, 0.71 ± 0.15 [0.34-1.08] ng/mL [p < 0.01]; free triiodothyronine, 2.56 ± 0.49 [1.33-3.79] pg/mL [p < 0.01]). There was no evidence of hyperthyroidism or suppression of the pituitary-thyroid axis in either treatment group Oral triiodothyronine supplementation at a dose of 0.5 mcg/kg every 12 hours for 3 days can maintain total and free triiodothyronine levels within normal limits after open-heart surgery using cardiopulmonary

ABSTRACT Worldwide 75 million women need postabortion care (PAC) services each year following safe or unsafe induced abortions and miscarriages. We reviewed more than 550 studies on PAC published between 1994 and 2013 in the peer-reviewed and gray literature, covering emergency treatment, postabortion family planning, organization of services, and related topics that impact practices and health outcomes, particularly in the Global South. In this article, we present findings from studies with strong evidence that have major implications for programs and practice. For example, vacuum aspiration reduced morbidity, costs, and time in comparison to sharp curettage. Misoprostol 400 mcg sublingually or 600 mcg orally achieved 89% to 99% complete evacuation rates within 2 weeks in multiple studies and was comparable in effectiveness, safety, and acceptability to manual vacuum aspiration. Misoprostol was safely introduced in several PAC programs through mid-level providers, extending services to secondary hospitals and primary health centers. In multiple studies, postabortion family planning uptake before discharge increased by 30–70 percentage points within 1–3 years of strengthening postabortion family planning services; in some cases, increases up to 60 percentage points in 4 months were achieved. Immediate postabortion contraceptive acceptance increased on average from 32% before the interventions to 69% post-intervention. Several studies found that women receiving immediate postabortion intrauterine devices and implants had fewer unintended pregnancies and repeat abortions than those who were offered delayed insertions. Postabortion family planning is endorsed by the professional organizations of obstetricians/gynecologists, midwives, and nurses as a standard of practice; major donors agree, and governments should be encouraged to provide universal access to postabortion family planning. Important program recommendations include offering all postabortion women

To evaluate the efficacy and safety of an ascending-dose, extended-regimen (ADER) combined oral contraceptive consisting of levonorgestrel (LNG) 150 mcg/ethinyl estradiol (EE) 20 mcg for 42 days, LNG 150 mcg/EE 25 mcg for 21 days, LNG 150 mcg/EE 30 mcg for 21 days and EE 10 mcg for 7 days. This was a multicenter, open-label, phase 3, single-arm study. Sexually active women aged 18-40 years were enrolled and received ADER for up to 1 year (4 consecutive 91-day cycles). Participants kept diaries to record adherence, bleeding/spotting and other contraceptive use. Efficacy was measured using the Pearl Index and the life-table method; safety and tolerability were assessed through reported adverse events (AEs). A total of 3701 women were enrolled and 2144 completed the study. The Pearl Index was 3.19 [95% confidence interval (CI), 2.49-4.03], based on 70 pregnancies that occurred after ADER initiation and ≤ 7 days after the last LNG/EE or EE-only pill in women aged 18-35 years, excluding cycles in which another contraceptive method was used. Life-table pregnancy rate was 2.82% (95% CI, 2.23%-3.57%) for all users aged 18-35 years. Unscheduled bleeding/spotting decreased with increasing EE doses within each cycle and decreased after cycle 1. No unexpected AEs or changes in laboratory parameters were reported. This study demonstrated that ADER effectively prevented pregnancy with a favorable safety and tolerability profile. Copyright © 2014 The Authors. Published by Elsevier Inc. All rights reserved.

Prostaglandin analogues of the E-series theoretically offer the ideal antiulcer drugs. Peptic ulcer healing with prostaglandin analogues is, however, no better than would be predicted from their ability to inhibit gastric acid secretion and they are less effective than histamine H2 receptor antagonists in preventing ulcer relapse. It could be that prostaglandin analogues inhibit gastric mucosal synthesis or release of endogenous eicosanoids, thereby abrogating their own effects. This study, therefore, examined how a single therapeutic dose (200 micrograms) of misoprostol, a synthetic analogue of prostaglandin E1, influences gastric mucosal release of endogenous prostaglandin E2 (PGE2), thromboxane B2 (TXB2), and chemotactic leukotriene B4 (LTB4) during basal conditions and in response to gastric luminal acidification (0.1 M HCl; 5 ml/min for 10 minutes). Nine healthy volunteers were studied in a single blind, cross over design. In each subject misoprostol or placebo was instilled in randomised order into the stomach, which was subsequently perfused with isotonic mannitol. Misoprostol significantly decreased basal as well as acid stimulated output of PGE2 and TXB2, without affecting output of LTB4. These data show that misoprostol inhibits gastric mucosal synthesis of prostanoids. Decreased concentrations, or even a changed profile, of native eicosanoids modulating the release of inflammatory mediators from immune cells might explain why prostaglandin analogues have a comparatively poor clinical performance in ulcer healing and prevention.

Combined oral contraceptives (COCs) may increase the risk for cardiovascular disease depending on the ethynyl estradiol (EE) dose and the androgenicity of the progestogens. Our objective was to evaluate the impact of a COC containing 20 mcg EE + 3 mg drospirenone on blood pressure (BP), renin-angiotensin-aldosterone system, insulin resistance, and androgenic profile of healthy young women. Eighty-one healthy young women aged 30 ± 1 years (case group, n = 49, received COC; control group, n = 32, used no COC) were assessed twice, before and after the 6-month study. Statistical analysis employed the paired t-tests and expressed the data in mean and standard deviation. Results were as follows: no changes in BP or in BMI; a significant increase in aldosterone, plasma renin activity, triglycerides, and total cholesterol levels, but a non-significant increase in HDL and no significant changes in LDL levels (these parameters remained within normal ranges); a significant increase in the HOMA-IR index and a significant decrease in dehydroepiandrosterone sulfate (SDHEA), androstenedione, total testosterone, and free testosterone levels; no significant variations in the control group parameters. An oral contraceptive combination of a low EE dose and an anti-androgenic progestogen does not negatively influence the risk factors for a cardiovascular disease.

Misoprostol is a synthetic prostaglandin E1 analogue which is mainly used for prevention and treatment of gastric ulcers, but also for abortion due to its labour inducing effect. Misoprostol exists as a mixture of diastereoisomers (1:1) and has several related impurities owing to its instability at higher temperatures and moisture. A simple and robust reversed phase liquid chromatographic (RPLC) method is described for the separation of the related substances and a normal phase (NP) LC method for the separation of misoprostol diastereoisomers. The RPLC method was performed using an Ascentis Express C18 (150 mm × 4.6 mm, 5 μm) column kept at 35 °C. The mobile phase was a gradient mixture of mobile phase A (ACN-H2O-MeOH, 28:69:3 v/v/v) and mobile phase B (ACN-H2O-MeOH, 47:50:3 v/v/v) eluted at a flow rate of 1.5 mL/min. UV detection was performed at 200 nm. The NPLC method was undertaken by using an XBridge bare silica (150 mm × 2.1 mm, 3.5 μm) column at 35 °C. The mobile phase contained 1-propanol-heptane-TFA (4:96:0.1%, v/v/v), pumped at a flow rate of 0.5 mL/min. UV detection was performed at 205 nm. This LC method can properly separate the two diastereoisomers (Rs > 2) within an analysis time of less than 20 min. Both methods were validated according to the ICH guidelines. Furthermore, these new LC methods have been successfully applied for purity control and diastereoisomers ratio determination of misoprostol bulk drug, tablets and dispersion.

To evaluate the acceptability and efficacy of medical abortion at home up to 63 days' gestation without limits on travel distance to a registered institution. Observational prospective study. Haukeland University Hospital between May 2006 and May 2009. A total of 1018 women requesting abortion before 63 days' gestation who chose medical termination with mifepristone and home administration of misoprostol. The women took 200 mg mifepristone under nurse supervision and self-administered 800 μg misoprostol vaginally 36-48 h later at home. All were contacted by phone for follow-up and assessment of bleeding, pain and acceptability. Evacuation rate, pain, bleeding, acceptability, influence of distance on treatment. Median gestational age was 50 (range 35-63) days and 70 (7.1%) of the women lived more than 60 min travel from the clinic. The rate of completed abortion was 93.6% and surgical evacuation was performed in 50 (4.9%) cases. Two women requested treatment on the day of misoprostol use. Moderate to strong pain was experienced by 68.4%, and 74.7% reported moderate to heavy bleeding. Parous women experienced less pain than nulliparous women (odds ratio 0.27; 95% confidence interval 0.19-0.34). In all, 95.1% of the women were satisfied with staying at home. Travel distance did not influence treatment outcome variables. In our experience, home administration of misoprostol is an effective and acceptable method for abortion up to 63 days of gestation and women should be eligible for this treatment option regardless of their travel distance from hospital. © 2014 The Authors.

The aim of the study was to compare the efficacy of sublingual misoprostol in addition to intravenous oxytocin, with oxytocin alone, in reducing blood loss during and following caesarean section. A total of 120 women undergoing caesarean delivery at the University College Hospital, Ibadan, were randomised into two equal groups. In Group A, 20 IU of intravenous oxytocin was given after umbilical cord clamping, while in Group B, the women received 400 μg misoprostol sublingually and 20 IU oxytocin intravenously. The outcome measures were blood loss, additional uterotonics, change in packed cell volume and side-effect profile. Associations between variables were determined by the χ(2) and Student's t-test. Relative risks were calculated for side-effects; the level of significance was p < 0.05. Intraoperative and postoperative blood loss were significantly lower in Group B (451.3 ml vs 551.2 ml, p = 0.007; 22.7 vs 42.2 ml, p < 0.001, respectively). In Group B, women were 7.4 (p < 0.001) and 9.0 (p = 0.008) times more likely to experience shivering and fever, respectively. The need for additional uterotonics was greater in the oxytocin group (66.7% vs 27.6%, p < 0.001). The addition of sublingual misoprostol to intravenous oxytocin reduces postpartum blood loss and the need for additional uterotonics. There is however, an increased risk of shivering and fever with this combination.

A pilot study to determine if the synthetic prostaglandin E1 misoprostol is effective in treating severe tinnitus, to test the hypothesis that tinnitus production is related to prostaglandin metabolism. Blinded, placebo controlled, hemicrossover. House Ear Clinic, Los Angeles, Calif. A volunteer and convenience sample of 24 subjects complaining of severe tinnitus was recruited from mailings, telephone calls, and the clinic population. The patients were not preselected except to be in otherwise good health. Subjects were started on a regimen of placebo or 200 micrograms/d of misoprostol. The dosage was increased every 5 days by 200 micrograms until a total of 800 micrograms/d was achieved. After 1 month of drug administration, the placebo group was crossed over to the active drug phase. Outcome was measured in terms of subjective reports of tinnitus severity, sleep patterns, and ability to concentrate. Eight (33%) of the 24 patients reported improvement during the active drug phase. There were no placebo responders. Responders reported improvement in tinnitus severity, sleep, and concentration. Findings support the contention that prostaglandins may be useful in the treatment of tinnitus. Further studies with larger samples are needed before widespread use of this intervention can be recommended.

While Pakistan has made progress toward achieving Millennium Development Goal 5 for maternal health, it is unlikely to achieve the target; further, it is also not on track for Millennium Development Goal 4 regarding child health. Two low-cost, temperature stable and life-saving drugs, misoprostol and chlorhexidine, can respectively avert maternal and newborn deaths, and are particularly pertinent for poor and marginalized areas which bear the brunt of maternal and newborn deaths in Pakistan. In response, Mercy Corps led focused advocacy efforts to promote changes in policies, protocols, and regulatory environments for misoprostol (2012-2014) and for chlorhexidine (2014). These short-duration advocacy projects facilitated significant policy gains, such as inclusion of misoprostol and chlorhexidine into province-specific essential drug lists, development and endorsement of clinical protocols for the two drugs by provincial health departments, inclusion of misoprostol into pre-service training curriculum for several health cadres, and application for registration of chlorhexidine (at the concentration required for newborn care) by two pharmaceutical companies. These results were achieved by a consultative and evidence-based process which generated feedback from community members, program implementers, and policymakers, and ultimately put the government in the driver's seat to facilitate change. Community Action Dialogue forums were linked with provincial-level Technical Working Groups and Provincial Steering Committees, who passed on endorsed recommendations to the Health Secretary. The key factors which facilitated change were the identification of champions within the provincial health departments, prioritization of relationship building and follow-up, focus on concrete advocacy aims rather than broad objectives, and the use of multi-stakeholder forums to secure an enabling environment for the policy changes to take root. While these advocacy initiatives resulted in

In order to extract decision rules for fault diagnosis from incomplete historical test records for knowledge-based damage assessment of helicopter power train structure. A method that can directly extract the optimal generalized decision rules from incomplete information based on GrC was proposed. Based on semantic analysis of unknown attribute value, the granule was extended to handle incomplete information. Maximum characteristic granule (MCG) was defined based on characteristic relation, and MCG was used to construct the resolution function matrix. The optimal general decision rule was introduced, with the basic equivalent forms of propositional logic, the rules were extracted and reduction from incomplete information table. Combined with a fault diagnosis example of power train, the application approach of the method was present, and the validity of this method in knowledge acquisition was proved.

Independent component analysis (ICA) algorithms have been successfully used for signal extraction tasks in the field of biomedical signal processing. We studied the performances of six algorithms (FastICA, CubICA, JADE, Infomax, TDSEP and MRMI-SIG) for fetal magnetocardiography (fMCG). Synthetic datasets were used to check the quality of the separated components against the original traces. Real fMCG recordings were simulated with linear combinations of typical fMCG source signals: maternal and fetal cardiac activity, ambient noise, maternal respiration, sensor spikes and thermal noise. Clusters of different dimensions (19, 36 and 55 sensors) were prepared to represent different MCG systems. Two types of signal-to-interference ratios (SIR) were measured. The first involves averaging over all estimated components and the second is based solely on the fetal trace. The computation time to reach a minimum of 20 dB SIR was measured for all six algorithms. No significant dependency on gestational age or cluster dimension was observed. Infomax performed poorly when a sub-Gaussian source was included; TDSEP and MRMI-SIG were sensitive to additive noise, whereas FastICA, CubICA and JADE showed the best performances. Of all six methods considered, FastICA had the best overall performance in terms of both separation quality and computation times.

Surgical versus expectant management in women with an incomplete evacuation of the uterus after treatment with misoprostol for miscarriage: the MisoREST trial

PubMed Central

2013-01-01

Background Medical treatment with misoprostol is a non-invasive and inexpensive treatment option in first trimester miscarriage. However, about 30% of women treated with misoprostol have incomplete evacuation of the uterus. Despite being relatively asymptomatic in most cases, this finding often leads to additional surgical treatment (curettage). A comparison of effectiveness and cost-effectiveness of surgical management versus expectant management is lacking in women with incomplete miscarriage after misoprostol. Methods/Design The proposed study is a multicentre randomized controlled trial that assesses the costs and effects of curettage versus expectant management in women with incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage. Eligible women will be randomized, after informed consent, within 24 hours after identification of incomplete evacuation of the uterus by ultrasound scanning. Women are randomly allocated to surgical or expectant management. Curettage is performed within three days after randomization. Primary outcome is the sonographic finding of an empty uterus (maximal diameter of any contents of the uterine cavity < 10 millimeters) six weeks after study entry. Secondary outcomes are patients’ quality of life, surgical outcome parameters, the type and number of re-interventions during the first three months and pregnancy rates and outcome 12 months after study entry. Discussion This trial will provide evidence for the (cost) effectiveness of surgical versus expectant management in women with incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage.

Poland syndrome has been attributed to a process of vascular disruption, and exposure to misoprostol at 6-8 weeks of gestation has been shown to produce defects attributed to vascular disruption. Herein we report the first case of a patient with Poland syndrome associated with an aberrant subclavian artery and vascular abnormalities of the retina, whose mother used misoprostol during pregnancy. A White boy of 1 year and 7 months of age, whose mother used misoprostol during the second month of pregnancy, presented with bilateral epicanthal folds, aplasia of the sternocostal head of the pectoralis major muscle with a hypoplastic nipple on the right side, and asymmetry between the upper limbs. The results of an angiotomographic study showed the presence of an aberrant right subclavian artery. Ultrasonographic evaluation showed turbulence and a high peak in the diastolic velocity in both carotid arteries, suggesting stenosis. Ophthalmologic assessment disclosed an intense bilateral tortuosity of the retinal blood vessels, with arterialnarrowing and rarefaction of the retinal pigment epithelium. This case suggests that the mechanism of vascular disruption of misoprostol could be related to the aberrant subclavian artery and the observed Poland syndrome. His retinal findings are different from those in cases described thus far in the literature, and this pattern of anomaly has never been associated with a gestational exposure to misoprostol. The possibility of a relationship of the aberrant right subclavian artery and the pattern of blood flow verified in the carotid arteries with the eye fundus abnormalities could be causally related or simply coincidental.

In Peru, abortion is legal only to preserve the life and health of the woman. A non-profit clinic system in Peru implemented a harm-reduction model for women with unwanted pregnancy that included pre-abortion care with instructions about misoprostol use and post-abortion care; they started offering telephone follow-up for clients in 2011. This study aimed to evaluate the effectiveness and safety of the harm-reduction model, and to compare outcomes by type of follow-up obtained. Between January 2012 and March 2013, 500 adult women seeking harm-reduction services were recruited into the study. Telephone surveys were conducted approximately four weeks after their initial harm-reduction counseling session with 262 women (response rate 52%); 9 participants were excluded. The survey focused on whether women pursued an abortion, and if so, what their experience was. Demographic and clinical data were also extracted from clinic records. Eighty-six percent of participants took misoprostol; among those taking misoprostol, 89% reported a complete abortion at the time of the survey. Twenty-two percent obtained an aspiration after taking misoprostol and 8% self-reported adverse events including hemorrhage without transfusion, infection, or severe pain. Among women who took misoprostol, 46% reported receiving in-person follow-up (in some cases both telephone and in-person), 34% received telephone only, and 20% did not report receiving any form of follow-up. Those who had in-person follow-up with the counselor were most likely to report a complete abortion (<0.001). Satisfaction with both types of follow-up was very high, with 81%-89% reporting being very satisfied. Liberalization of restrictive abortion laws is associated with improvements in health outcomes, but the process of legal reform is often lengthy.

Objectives The need for thorough patient information is increasing as maternity care becomes more medicalised. The aim was to assess the quality of written patient information on labour induction. In most Danish hospitals, misoprostol is the first-choice drug for induction in low-risk pregnancies. Misoprostol has been associated with adverse side effects and severe outcomes for mother and child and is not registered for obstetric use in Denmark. Setting Secondary care hospitals in Denmark. Data Patient information leaflets from all hospitals that used misoprostol as an induction agent by June 2015 (N=13). Design Patient leaflets were evaluated according to a validated scoring tool (International Patient Decision Aid Standards instrument, IPDAS), core elements in the Danish Health Act, and items regarding off-label use and non-registered medication. Two of the authors scored all leaflets independently. Outcome measures Women's involvement in decision-making, information on benefits and harms associated with the treatment, other justifiable treatment options, and non-registered treatment. Results Generally, the hospitals scored low on the IPDAS checklist. No hospitals encouraged women to consider their preferences. Information on side effects and adverse outcomes was poorly covered and varied substantially between hospitals. Few hospitals informed about precautions regarding outpatient inductions, and none informed about the lack of evidence on the safety of this procedure. None informed that misoprostol is not registered for induction or explained the meaning of off-label use or use of non-registered medication. Elements such as interprofessional consensus, long-term experience, and health authorities' approval were used to add credibility to the use of misoprostol. Conclusions Central criteria for patient involvement and informed consent were not met, and the patient leaflets did not inform according to current evidence on misoprostol-induced labour.

[Misoprostol: pathways, mediation and social networks for access to abortion using medication in the context of illegality in the State of Sao Paulo].

PubMed

Arilha, Margareth Martha

2012-07-01

The scope of this article is to discuss the commercialization and use of misoprostol for abortion purposes in the illegal contexts that still persist in Brazil. The information presented was collected through case studies conducted with two young women who aborted using medication - one successfully and one unsuccessfully - and two adult women who have close ties with women who used misoprostol. The study confirms the hypothesis that the diffusion and expansion of the use of misoprostol outside the hospital context is associated with the decision of women who seek lower costs, lower risks to their health and privacy. It also permits examination of the interpretation that this increase in consumption is linked to the inclusion of the medication in a set of goods that are illegally traded in Brazil, in different ways and in different contexts. As a result, women are exposed to different degrees of vulnerability depending directly on the steps taken, types of mediation used and social networks they belong to. These are the ways in which women and men obtain access to the use of misoprostol for abortion, the outcome of which may be successful or not.

Performance comparison of six independent components analysis algorithms for fetal signal extraction from real fMCG data

In this study we compare the performance of six independent components analysis (ICA) algorithms on 16 real fetal magnetocardiographic (fMCG) datasets for the application of extracting the fetal cardiac signal. We also compare the extraction results for real data with the results previously obtained for synthetic data. The six ICA algorithms are FastICA, CubICA, JADE, Infomax, MRMI-SIG and TDSEP. The results obtained using real fMCG data indicate that the FastICA method consistently outperforms the others in regard to separation quality and that the performance of an ICA method that uses temporal information suffers in the presence of noise. These two results confirm the previous results obtained using synthetic fMCG data. There were also two notable differences between the studies based on real and synthetic data. The differences are that all six ICA algorithms are independent of gestational age and sensor dimensionality for synthetic data, but depend on gestational age and sensor dimensionality for real data. It is possible to explain these differences by assuming that the number of point sources needed to completely explain the data is larger than the dimensionality used in the ICA extraction.

Examine the feasibility of introducing mifepristone-misoprostol medication abortion into existing public sector surgical abortion services in KwaZulu-Natal, South Africa. Cohort study of women offered medication or surgical abortion in a larger medication abortion introduction study. The sample included 1167 women seeking first-trimester abortion at four public sector facilities; 923 women at ≤9 weeks' gestation were eligible for medication abortion. Women who chose medication abortion took 200 mg of mifepristone orally at the facility and 800 mcg of misoprostol buccally (or vaginally if they anticipated or experienced problems with buccal administration) 48 h later at home, based on international research and global safe abortion guidelines. Women who chose surgical abortion received 600 mg of misoprostol sublingually or vaginally on the day of their procedure followed by manual vacuum aspiration 4 h later. Main outcome measures included proportion of eligible women who chose each method, proportion with complete abortion and proportion reporting adverse events. Ninety-four percent of eligible women chose medication abortion. No adverse events were reported by women who chose surgical abortion; 3% of women in the medication abortion group reported adverse events and 0.4% reported a serious adverse event. Seventy-six percent of women received a family planning method at the facility where their received their abortion, with no difference based on procedure type. Medication abortion patients were significantly more likely to report they would choose this method again (94% vs. 78%, p<.001) and recommend the method to a friend (98% vs. 84%, p<.001). Medication abortion was successfully introduced with low and acceptable rates of adverse events; most women at study facilities chose this option. Mifepristone-misoprostol medication abortion was successfully integrated into public sector surgical abortion services in South Africa and was chosen by a large majority of

Objective: To perform hysteroscopy the cervix needs to be dilated and in nullipara and postmenopausal women this is sometimes difficult. Well-known, entry-related complications during hysteroscopy include cervical tear, creation of false tract, bleeding, uterine perforation, scarring, and subsequent anatomical stenosis. Materials and Methods: This study was done to investigate the priming effect of vaginal misoprostol on cervical dilatation in postmenopausal women, before hysteroscopy, to prevent such complications. Two hundred micrograms of misoprostol was inserted into the vagina at least 12 hours before the procedure and the control group did not receive any cervical priming agent. Pre-procedural dilatation, additional dilatation required, and time taken for dilatation was noted in each case. Observations: The study showed a significant difference between the study group (7.7 ± 1.7 mm) and the control group (4.5 ± 1.8 mm) in terms of pre-procedural cervical width and the number of women requiring a dditional dilatation (7 / 25 versus 22 / 25), and hence, the time required for dilatation (4.7 ± 8 seconds versus 20.6 ± 9.3 seconds). Conclusion: The pre-procedural cervical width was significantly more in the study group as compared to that in the control group. We found significant differences between the study and control groups with respect to the number of women who required cervical dilatation. To conclude, this study helps derive a conclusion that vaginal misoprostol as a cervical priming agent in postmenopausal women appears to be safe, effective, and inexpensive, with mild side effects.

A 50-fold disparity in maternal mortality exists between high- and low-income countries, and in most contexts, the single most common cause of maternal death is postpartum hemorrhage (PPH). In Bangladesh, as in many other low-income countries, the majority of deliveries are conducted at home by traditional birth attendants (TBAs) or family members. In the absence of skilled birth attendants, training TBAs in the use of misoprostol and an absorbent delivery mat to measure postpartum blood loss may strengthen the ability of TBAs to manage PPH. These complementary interventions were tested in operations research among 77,337 home births in rural Bangladesh. The purpose of this study was to evaluate TBAs' knowledge acquisition, knowledge retention, and changes in attitudes and practices related to PPH management in home births after undergoing training on the use of misoprostol and the blood collection delivery mat. We conclude that the training was highly effective and that the two interventions were safely and correctly used by TBAs at home births. Data on TBA practices indicate adherence to protocol, and 18 months after the interventions were implemented, TBA knowledge retention remained high. This program strengthens the case for community-based use of misoprostol and warrants consideration of this intervention as a potential model for scale-up in settings where complete coverage of skilled birth attendants (SBAs) remains a distant goal.

As part of an ongoing study of the neutral hydrogen (H I) morphology and kinematics of 'shell' elliptical galaxies, we present Very Large Array observations of two shell galaxies with aligned shells, Arp 230 and MCG -5-7-1. Our data provide the first H I images of Arp 230 and deeper images of MCG -5-7-1 than previously reported. Optical images of Arp 230 reveal a bright, aligned, interleaved shell system, making it an ideal candidate for 'phase-wrapped' shell formation following a radial encounter with a smaller companion. The fainter, non-interleaved shells of MCG -5-7-1 do not clearly favor a particular formationmore » scenario. The H I we detect in both galaxies extends to nearly the same projected distance as the optical shells. In Arp 230 this gas appears to be anti-correlated with the aligned shells, consistent with our expectations for phase-wrapped shells produced in a radial encounter. In MCG -5-7-1, we observe gas associated with the shells making a 'spatial wrapping' or looping scenario more plausible. Although the extended gas component in both galaxies is unevenly distributed, the gas kinematics are surprisingly regular, looking almost like complete disks in rotation. We use the H I kinematics and optical data to determine mass-to-light ratios M/L{sub B} of 2.4{sup +3.0}{sub -0.5} (at 13.5 kpc, 4.5 R{sub e} ) for Arp 230 and M/L{sub B} of 30 {+-} 7 (at 40 kpc, 7 R{sub e} ) in MCG -5-7-1. In both systems we find that this ratio changes as a function of radius, indicating the presence of a dark halo. By comparing orbital and precession timescales, we conclude that the potentials are slightly flattened. We infer a 5%-10% flattening for Arp 230 and less flattening in the case of MCG -5-7-1. Finally, we present images of the H I associated with the inner disk or (polar) ring of each galaxy and discuss possible explanations for their different present-day star formation rates. We detect total H I masses of 1.1 Multiplication-Sign 10{sup 9} M{sub Sun} in

To compare the efficacy and acceptability of combined hormonal vaginal ring with combined oral hormonal pill in women with idiopathic chronic pelvic pain. Randomised prospective interventional trial conducted in 60 women with idiopathic chronic pelvic pain. Women were randomised into two groups of 30 each. In each group, treatment was given for 84 days using either combined vaginal ring or combined oral hormonal pill. Hormonal vaginal ring releases 15mcg of ethinyl estradiol and 120mcg of the etonogestrel per day while the hormonal pill contained 30mcg of ethinyl estradiol and 150mcg of levonorgestrel. There was no ring or pill free week. After every 28 days, pain relief was measured using visual analogue scale (VAS), and verbal rating score (VRS) calculated by summing dysmenorrhea, non-cyclic pelvic pain (NCCP) and deep dyspareunia scores. Side effects, compliance, satisfaction, and user acceptability were also measured. Data was analyzed using various parametric and non-parametric tests. Reduction in mean VAS score at end of treatment in ring group was 6.23 (95% confidence interval [CI], 5.45-7.01; p<0.001) as compared to 5.53 in pill group (95% CI, 4.83-6.23; p<0.001). Reduction in mean VRS score was 5.63 in ring users (95% CI, 4.84-6.42; p<0.001) versus 4.36 in pill users (95% CI, 3.63-5.10; p<0.001). A significantly higher persistent relief in NCPP score was observed in vaginal ring group as compared to oral pill group at end of one month after stopping treatment. Compliance, satisfaction, and user acceptability were higher in ring users (80%) than pill users (70%) and a higher incidence of nausea was seen in pill group. Present study demonstrates for first time that both vaginal and oral hormonal therapy are effective in treatment of idiopathic chronic pelvic pain and vaginal ring may be a better choice with higher satisfaction rate and fewer side effects.

To test the efficacy of misoprostol as a treatment for tinnitus. A prospective, placebo-controlled, double-blind study. Başkent University Otolaryngology Clinic. Forty adult patients who had had tinnitus for a minimum of 6 months and were free of systemic or otolaryngologic disease. Twenty-eight patients were randomly assigned to the experimental group (group I) and 12 to the control group (group II). The respective groups received active drug and placebo in increasing doses for 4 months. The effect of medications on tinnitus were evaluated by determining improvement rates in tinnitus loudness and subjective tinnitus scoring. In the experimental group, 18 of 28 patients showed improvement in tinnitus loudness, representing an improvement rate of 64%. The improvement rate based on subjective tinnitus scoring was 36% (10 of 28 patients). In the control group, the improvement rate for tinnitus loudness was 33% (n = 4), and the rate for subjective tinnitus scoring was 17% (n = 2). The difference between improvement rate for tinnitus loudness of the experimental group and control group was found to be statistically significant (P = 0.039), but difference between improvement rate based on subjective tinnitus scoring was insignificant (P = 0.119). When results in the experimental group were analyzed according to etiological factors, the improvement rate was highest in the sudden-onset subgroup (77%). Misoprostol provided therapeutic relief for some patients with tinnitus we studied, but further investigation of larger groups is needed.

Background Postpartum haemorrhage (PPH) is a leading cause of maternal death in Sokoto State, Nigeria, where 95% of women give birth outside of a health facility. Although pilot schemes have demonstrated the value of community-based distribution of misoprostol for the prevention of PPH, none have provided practical insight on taking such programs to scale. Methods A community-based system for the distribution of misoprostol tablets (in 600ug) and chlorhexidine digluconate gel 7.1% to mother-newborn dyads was introduced by state government officials and community leaders throughout Sokoto State in April 2013, with the potential to reach an estimated 190,467 annual births. A simple outcome form that collected distribution and consumption data was used to assess the percentage of mothers that received misoprostol at labor through December 2014. Mothers’ conditions were tracked through 6 weeks postpartum. Verbal autopsies were conducted on associated maternal deaths. Results Misoprostol distribution was successfully introduced and reached mothers in labor in all 244 wards in Sokoto State. Community data collection systems were successfully operational in all 244 wards with reliable capacity to record maternal deaths. 70,982 women or 22% of expected births received misoprostol from April 2013 to December 2014. Between April and December 2013, 33 women (< 1%) reported that heavy bleeding persisted after misoprostol use and were promptly referred. There were a total of 11 deaths in the 2013 cohort which were confirmed as maternal deaths by verbal autopsies. Between January and December of 2014, a total 434 women (1.25%) that ingested misoprostol reported associated side effects. Conclusion It is feasible and safe to utilize government guidelines on results-based primary health care to successfully introduce community distribution of life saving misoprostol at scale to reduce PPH and improve maternal outcomes.

The role of prostaglandins E1 and E2, dinoprostone, and misoprostol in cervical ripening and the induction of labor: a mechanistic approach.

PubMed

Bakker, Ronan; Pierce, Stephanie; Myers, Dean

Prostaglandins play a critical role in cervical ripening by increasing inflammatory mediators in the cervix and inducing cervical remodeling. Prostaglandin E1 (PGE1) and prostaglandin E2 (PGE2) exert different effects on these processes and on myometrial contractility. These mechanistic differences may affect outcomes in women treated with dinoprostone, a formulation identical to endogenous PGE2, compared with misoprostol, a PGE1 analog. The objective of this review is to evaluate existing evidence regarding mechanistic differences between PGE1 and PGE2, and consider the clinical implications of these differences in patients requiring cervical ripening for labor induction. We conducted a critical narrative review of peer-reviewed articles identified using PubMed and other online databases. While both dinoprostone and misoprostol are effective in cervical ripening and labor induction, they differ in their clinical and pharmacological profiles. PGE2 has been shown to stimulate interleukin-8, an inflammatory cytokine that promotes the influx of neutrophils and induces remodeling of the cervical extracellular matrix, and to induce functional progesterone withdrawal. Misoprostol has been shown to elicit a dose-dependent effect on myometrial contractility, which may affect rates of uterine tachysystole in clinical practice. Differences in the mechanism of action between misoprostol and PGE2 may contribute to their variable effects in the cervix and myometrium, and should be considered to optimize outcomes.

2011-01-01

Background This study was conducted to compare ovarian suppression during oral versus vaginal hormonal contraceptive use. Secondary aims included comparison of endometrial thickness and bleeding patterns. Methods In two open-label trials assessing ovarian suppression, 33 compliant women completed both studies. They first used OCs [randomized to either 20 mcg ethinyl estradiol (EE)/100 mcg levonorgestrel (LNG) or 30 mcg EE/150 mcg LNG] and subsequently used contraceptive vaginal rings (CVR) (daily release of 15 mcg EE/120 mcg etonogestrel), all 21/7 day regimens. Participants had at least one run-in cycle using each contraceptive method prior to evaluation. During one cycle of each method, women underwent bi-weekly transvaginal sonography to measure ovarian follicular diameters and endometrial thickness. We also noted presence of a corpus luteum or a ruptured follicle as a marker of ovulation. Participants recorded bleeding days on paper calendars. We used matched pairs analyses as appropriate. Results During follow-up, we identified at least one ovarian follicle ≥8 mm in 20/33 (61%) OC users and 12/33 (36%) CVR users (matched pairs analysis, p=0.02). Similar trends were seen for larger follicles; however we had limited statistical power to evaluate these differences. Median follicular diameter among OC users was larger than median follicular diameter among CVR users (p=0.01). We did not observe a corpus luteum or ruptured follicle in any participant during either study. Endometrial thickness was similar during OC and CVR use (mean 4.1 ± 1.4 mm versus 4.1 ± 1.6 mm, p=0.9) as was the number of bleeding or spotting days (mean 2.1 ± 2.4 versus 1.9 ± 2.1, p=0.8). OC dose was unrelated to follicle diameter, endometrial thickness, or bleeding. Conclusions Ovarian follicles ≥8 mm were more common in 33 compliant women during OC use than during CVR use indicating CVR use results in greater ovarian suppression than OC use. PMID:22018131

To evaluate the efficacy of a combined protocol of mifepristone and misoprostol in the management of early pregnancy failure (EPF) and the average time to expulsion of tissue and rate of side effects. Retrospective chart review of all consecutive women treated with primary medical management for EPF at our institution from 2006 to 2012. 168 patients were included in the present study. The overall success rate, defined as the absence of the need for surgical intervention, was 61 % and did not differ by calendar year. There was no difference in success rate grouped by diagnosis [intrauterine embryonic/fetal demise (IUED/IUFD) vs. anembryonic gestation; p = 0.30] or gestational age (<9 or ≥9 weeks; p = 0.48). The success rate varied significantly according to the required dose of misoprostol, ≤800 or >800 μg (68 vs. 50 %, p = 0.029). Of the possible predictive factors of success, only the dose of misoprostol required was a significant independent negative predictor. Mean and median time to tissue expulsion after the first dose of misoprostol were 8.4 and 5.5 h, respectively. The incidence of side effects was low with no blood transfusions required. The success rate in this study is markedly below published data. This can possibly be attributed to retrospective study design, allowing for physician subjectivity and patients' wishes in the absence of strict study requirements. The protocol was well tolerated with a paucity of side effects. We make suggestions for enhancing success rates in the clinical setting by optimizing medication protocols, establishing precise treatment guidelines and training physicians in the accurate interpretation of treatment outcomes.

This study describes ovarian activity suppression of a 21/7-active low-dose combined oral contraceptive (COC) regimen that included only ethinyl estradiol (EE) during the traditional hormone-free interval (HFI) and two commercially available 28-day regimens, a 24/4 and a 21/7 regimen. The randomized, open-label, parallel-group descriptive study was conducted at two US sites. Healthy, reproductive-aged women (n=146) were randomized to one of three groups for three consecutive 28-day cycles, as follows: treatment 1 (n=39 completed): 21/7-active COC [21 days of 150 mcg desogestrel (DSG)/20 mcg EE, followed by 7 days of 10 mcg EE (DSG/EE+7 days EE)], treatment 2 (n=39 completed): 24 days of 3mg drospirenone (DRSP)/20 mcg EE, followed by 4 placebo (PBO)-pill days (DRSP/EE+4 days PBO) and treatment 3 (n=42 completed): 21 days of 100 mcg levonorgestrel (LNG)/20 mcg EE, followed by 7 PBO-pill days (LNG/EE+7 days PBO). The primary outcome was ovarian activity suppression assessed by transvaginal ultrasound and serum hormone concentrations and classified using the Hoogland and Skouby (H/S) method. Ovarian activity rate (H/S grade 4 or 5) was low for all three treatments: 0% [95% confidence interval (CI) 0-2.8] for DSG/EE+7 days EE, 1% (95% CI 0.2-5.2) for DRSP/EE+4days PBO and 1% (95% CI 0-3.9) for LNG/EE+7 days PBO. All three treatments showed similar suppression of serum progesterone, 17β-estradiol, follicle-stimulating hormone and luteinizing hormone levels. The 21/7-active low-dose COC regimen (DSG/EE+7 days EE) showed ovarian activity suppression that was similar to the 24/4 (DRSP/EE+4 days PBO) and 21/7 (LNG/EE+7days PBO) regimens. The 21/7-active low-dose COC regimen (DSG/EE+7 days EE) that included only EE during the traditional HFI showed suppression of ovarian follicular activity that was similar to the 24/4 (DRSP/EE+4days PBO) and the 21/7 (LNG/EE+7 days PBO) comparator regimens.

If we can do it for misoprostol, why not for mifepristone? The case for taking mifepristone out of the office in medical abortion.

PubMed

Gold, Marji; Chong, Erica

2015-09-01

Given the highly political nature of abortion in the United States, the provision of medical abortion with mifepristone (Mifeprex®) and misoprostol has always occurred under a unique set of circumstances. The Food and Drug Administration-approved regimen requires clinicians to administer the mifepristone in the office and also requires women to return to the office for the misoprostol. In the US, where off-label drug use is an accepted practice when supportive evidence exists, most clinicians give women the misoprostol at the initial visit for her to take at home, eliminating an unnecessary visit to the office. This commentary suggests that, based on current studies, there is also enough evidence to offer women the option to self-administer mifepristone out of the office and that this is just another feature of off-label use. Six studies, enrolling over 1800 women, found that the option of taking mifepristone out of the office was popular and acceptable among women and providers. Given that it is safe, highly acceptable and not burdensome on providers, outside-office-use of mifepristone should be offered to all women as part of routine medical abortion services.

Perspectives on variability in pharmacokinetics of an oral contraceptive product☆

PubMed Central

Jusko, William J.

2017-01-01

The early literature and reviews have described the pharmacokinetics (PK) of oral contraceptive (OC) compounds such as ethinyl estradiol (EE) and levonorgestrel (LNG) in women as subject to large intersubject variability. This was partly due to the use of diverse radioimmunoassays, limited sampling periods and an incomplete understanding of single- vs. multiple-dose kinetics and the role of EE in causing both inhibition of hepatic metabolism along with induction of sex hormone binding globulin. Over the past two decades, LNG and EE have been used as target drugs for the assessment of possible drug interactions upon introduction of many new therapeutic agents. This has resulted in at least 17 publications that describe the PK of LNG and EE in women using various 150 mcg/30 mcg products under fairly standard multiple-dose conditions. A review of these studies indicates only moderate variability in the Cmax and area under the curve both within and across these studies. There is impressive similarity in these drug exposure indices found in studies carried out with several products by investigators at numerous sites and countries. PMID:27475034

Prostaglandins for preventing postpartum haemorrhage.

Prostaglandins have mainly been used for postpartum haemorrhage (PPH) when other measures fail. Misoprostol, a new and inexpensive prostaglandin E1 analogue, has been suggested as an alternative for routine management of the third stage of labour. To assess the effects of prophylactic prostaglandin use in the third stage of labour. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (7 January 2011). We updated this search on 25 May 2012 and added the results to the awaiting classification section. Randomised trials comparing a prostaglandin agent with another uterotonic or no prophylactic uterotonic (nothing or placebo) as part of management of the third stage of labour. The primary outcomes were blood loss 1000 mL or more and the use of additional uterotonics. Two review authors independently assessed eligibility and trial quality and extracted data. We included 72 trials (52,678 women). Oral or sublingual misoprostol compared with placebo is effective in reducing severe PPH (oral: seven trials, 6225 women, not totalled due to significant heterogeneity; sublingual: risk ratio (RR) 0.66; 95% confidence interval (CI) 0.45 to 0.98; one trial, 661 women) and blood transfusion (oral: RR 0.31; 95% CI 0.10 to 0.94; four trials, 3519 women).Compared with conventional injectable uterotonics, oral misoprostol was associated with higher risk of severe PPH (RR 1.33; 95% CI 1.16 to 1.52; 17 trials, 29,797 women) and use of additional uterotonics, but with a trend to fewer blood transfusions (RR 0.84; 95% CI 0.66 to 1.06; 15 trials; 28,213 women). Additional uterotonic data were not totalled due to heterogeneity. Misoprostol use is associated with significant increases in shivering and a temperature of 38º Celsius compared with both placebo and other uterotonics. Oral or sublingual misoprostol shows promising results when compared with placebo in reducing blood loss after delivery. The margin of benefit may be affected by whether other components of the

The objectives were to evaluate the safety and acceptability of outpatient medical abortion in selected women without a pretreatment ultrasound or pelvic examination. We conducted a prospective case-series study to estimate the incidence of serious adverse events (death, life-threatening event, hospitalization, transfusion or any other medical problem that we judged to be significant), surgical completion of the abortion and satisfaction in women provided with medical abortion without a pretreatment ultrasound or pelvic examination. We enrolled 406 women requesting medical abortion in Moldova, Mexico and the United States. To be eligible, a woman must have been certain that her last menstrual period started within the prior 56days, have had regular menses before the pregnancy, not have used hormonal contraceptives in the prior 2months (in the United States and Mexico) or 3months (in Moldova), have no risk factors for or symptoms of ectopic pregnancy, and not have had an ultrasound or pelvic exam in this pregnancy. One site also excluded women with uterine enlargement on abdominal palpation. Each participant received mifepristone (200mg orally) and misoprostol (400 mcg sublingually in Moldova; 800 mcg buccally at all other sites) and was followed until complete abortion, defined as requiring no further treatment. Of the 365 (90%) participants who provided sufficient follow-up information for analysis, 347 (95%) had complete abortion without additional treatment, 5 (1%) had surgical aspiration, and 10 (3%) had extra misoprostol. Three participants (1%) had serious adverse events; these included two hospital admissions for heavy bleeding managed with aspiration and one diagnosis of persistent gestational sac 19days after enrollment. Most (317, 90%) participants were pleased with omitting the pretreatment ultrasound and pelvic exam. In this study, medical abortion without screening ultrasound or pelvic exam resulted in no serious adverse events that were likely to have

This clinical trial was conducted to demonstrate the efficacy and safety of a 91-day extended-regimen, low-dose combination oral contraceptive (OC) consisting of 84 days of ethinyl estradiol (EE) 20 mcg/levonorgestrel (LNG) 100 mcg, followed by 7 days of 10 mcg EE in place of placebo. A multicenter open-label, single-treatment, Phase 3 study evaluated women aged 18 through 40 years over a treatment period of up to 1 year (four 91-day extended cycles). All subjects completed daily paper diaries to monitor compliance, bleeding and additional forms of contraception used during the course of the study. A total of 1249 subjects completed the study. The Pearl Index was 2.74 (95% confidence interval, 1.92-3.78), based on 36 pregnancies that occurred after the onset of treatment and within 14 days after the last combination tablet in women aged 18-35 years. Among compliant-use subjects 18-35 years old, the Pearl Index was 1.73 based on 22 on-treatment pregnancies. The life table pregnancy rate for subjects 18-35 years of age was 2.39%. Cycle control and adverse events reported with this regimen were similar to those reported with other low-dose OCs. This study demonstrated effective prevention of pregnancy with a 20-mcg EE, 91-day extended-regimen OC. In addition, the regimen was well tolerated and incidence of adverse events were consistent with what has been reported with other low-dose OCs.

Clostridium sordellii toxic shock syndrome after medical abortion with mifepristone and intravaginal misoprostol--United States and Canada, 2001-2005.

PubMed

2005-07-29

On July 19, 2005, the Food and Drug Administration (FDA) issued a public health advisory regarding the deaths of four women in the United States after medical abortions with Mifeprex (mifepristone, formerly RU-486; Danco Laboratories, New York, New York) and intravaginal misoprostol. Two of these deaths occurred in 2003, one in 2004, and one in 2005. Two of these U.S. cases had clinical illness consistent with toxic shock and had evidence of endometrial infection with Clostridium sordellii, a gram-positive, toxin-forming anaerobic bacteria. In addition, a fatal case of C. sordellii toxic shock syndrome after medical abortion with mifepristone and misoprostol was reported in 2001, in Canada. All three cases of C. sordellii infection were notable for lack of fever, and all had refractory hypotension, multiple effusions, hemoconcentration, and a profound leukocytosis. C. sordellii previously has been described as a cause of pregnancy-associated toxic shock syndrome.

RXTE and BeppoSAX Observations of MCG-5-23-16: Reflection From Distant Cold Material

We examine the spectral variability of the Seyfert 1.9 galaxy MCG-5-23-16 using RXTE and BeppoSAX observations spanning 2 years from April 1996 to April 1998. During the first year the X-ray source brightens by a factor of approximately 25% on timescales of days to months. During this time, the reprocessed continuum emission seen with RXTE does not respond measurably to the continuum increase. However, by the end of the second year during the BeppoSAX epoch the X-ray source has faded again. This time, the reprocessed emission has also faded, indicating that the reprocessed flux has responded to the continuum. If these effects are caused by time delays due to the distance between the X-ray source and the reprocessing region, we derive a light crossing time of between approximately 1 light day and approximately 1.5 light years. This corresponds to a distance of 0.001 pc to 0.55 pc, which implies that the reprocessed emission originates between 3 x 10(exp 15) cm and 1.6 x 10(exp l8) cm from the X-ray source. In other words, the reprocessing in MCG-5-23-16 is not dominated by the inner regions of a standard accretion disk.

Abstract Background: Medical abortion with mifepristone and misoprostol was introduced in Norway in 1998, and since then there has been an almost complete change from predominantly surgical to medical abortions. We aimed to describe the medical abortion implementation process, and to compare characteristics of women obtaining medical and surgical abortion. Methods: Information from all departments of obstetrics and gynaecology in Norway on the time of implementation of medical abortion and abortion procedures in use up to 12 weeks of gestation was assessed by surveys in 2008 and 2012. We also analysed data from the National Abortion Registry comprising 223 692 women requesting abortion up to 12 weeks of gestation during 1998–2013. Results: In 2012, all hospitals offered medical abortion, 84.4% offered medical abortion at 9–12 weeks of gestation and 92.1% offered home administration of misoprostol. The use of medical abortion increased from 5.9% of all abortions in 1998 to 82.1% in 2013. Compared with women having a surgical abortion, women obtaining medical abortion had higher odds for undergoing an abortion at 4–6 weeks (adjusted OR 2.33; 95% confidence interval 2.28-2.38). Waiting time between registered request for an abortion until termination was reduced from 11.3 days in 1998 to 7.3 days in 2013. Conclusions: Norwegian women have gained access to more treatment modalities and simplified protocols for medical abortion. At the same time they obtained abortions at an earlier gestational age and the waiting time has been reduced. PMID:28031316

Background Most of the millions of oral contraceptive (OC) users are under age 30 years and in the critical period for bone mass accrual. Study Design This cross-sectional study of 606 women aged 14–30 years examined both OC duration and estrogen dose and their association with bone mineral density (BMD) at the hip, spine, and whole-body (DEXA). Results Of 389 OC users and 217 nonusers enrolled, 50% were adolescents (14–18 years). Of OC users, 38% used “low-dose” OCs [<30 mcg ethinyl estradiol (EE)]. In adolescents, mean BMD differed by neither OC duration nor EE dose. However, 19–30 year-old women’s mean BMD was lower with longer OC use for spine and whole-body (p=0.004, p=0.02, respectively) and lowest for >12 months of low-dose OCs for the hip, spine and whole-body (p=0.02, 0.003 and 0.002, respectively). Conclusions Prolonged use of today’s OCs, particularly <30 mcg EE, may adversely impact young adult women’s bone density while ingesting these agents. PMID:20004271

To compare efficacy and adverse effects of 200μg and 400μg misoprostol for prevention of postpartum hemorrhage (PPH). In a randomized control trial, women with term singleton pregnancies in active labor attending University College Hospital, Ibadan, Nigeria, were enrolled between July 2011 and February 2012. Participants were randomly assigned using random numbers (block size four) to receive 200μg or 400μg sublingual misoprostol after delivery of the anterior shoulder, alongside intravenous oxytocin. Investigators were masked to group assignment, but participants were not. The primary outcomes were blood loss up to 1h after delivery, PPH (blood loss ≥500mL), and adverse effects. Overall, 62 patients were assigned to each group. No significant differences between the 200-μg and 400-μg groups were recorded in mean peripartum blood loss (307±145mL vs 296±151mL; P=0.679) and PPH occurrence (5 [8.1%] vs 6 [9.7%] women; P=0.752). Noticeable adverse effects were reported by 16 (25.8%) women in the 200-μg group and 42 (67.7%) in the 400-μg group (P<0.001). Risk of shivering was significantly lower with 200μg than 400μg (relative risk 0.33, 95% confidence interval 0.19-0.58). Blood loss and PPH occurrence did not differ by misoprostol dose, but a 200-μg dose was associated with a reduction in adverse effects. Pan Africa Clinical Trials Registry: PACTR201505001107182.

Perspectives on variability in pharmacokinetics of an oral contraceptive product.

PubMed

Jusko, William J

2017-01-01

The early literature and reviews have described the pharmacokinetics (PK) of oral contraceptive (OC) compounds such as ethinyl estradiol (EE) and levonorgestrel (LNG) in women as subject to large intersubject variability. This was partly due to the use of diverse radioimmunoassays, limited sampling periods and an incomplete understanding of single- vs. multiple-dose kinetics and the role of EE in causing both inhibition of hepatic metabolism along with induction of sex hormone binding globulin. Over the past two decades, LNG and EE have been used as target drugs for the assessment of possible drug interactions upon introduction of many new therapeutic agents. This has resulted in at least 17 publications that describe the PK of LNG and EE in women using various 150 mcg/30 mcg products under fairly standard multiple-dose conditions. A review of these studies indicates only moderate variability in the C max and area under the curve both within and across these studies. There is impressive similarity in these drug exposure indices found in studies carried out with several products by investigators at numerous sites and countries. Copyright © 2016 Elsevier Inc.

In Myanmar, postpartum haemorrhage is the leading cause of maternal mortality and contributes to around 30% of all maternal deaths. The World Health Organization recommends training and supporting auxiliary midwives to administer oral misoprostol for prevention of postpartum haemorrhage in resource-limited settings. However, use of misoprostol by auxiliary midwives has not formally been approved in Myanmar. Our study aimed to explore community and provider perspectives on the roles of auxiliary midwives and community-level provision of oral misoprostol by auxiliary midwives. A qualitative inquiry was conducted in Ngape Township, Myanmar. A total of 15 focus group discussions with midwives, auxiliary midwives, community members and mothers with children under the age of three were conducted. Ten key informant interviews were performed with national, district and township level health planners and implementers of maternal and child health services. All audio recordings were transcribed verbatim in Myanmar language. Transcripts of focus group discussions were fully translated into English before coding, while key informants' data were coded in Myanmar language. Thematic analysis was done using ATLAS.ti software. Home births are common and auxiliary midwives were perceived as an essential care provider during childbirth in hard-to-reach areas. Main reasons provided were that auxiliary midwives are more accessible than midwives, live in the hard-to-reach areas, and are integrated in the community and well connected with midwives. Auxiliary midwives generally reported that their training involved instruction on active management of the third stage of labour, including use of misoprostol, but not all auxiliary midwives reported using misoprostol in practice. Supportive reasons for task-shifting administration of oral misoprostol to auxiliary midwives included discussions around the good relationship and trust between auxiliary midwives and midwives, whereby midwives felt

Objectives This study was conducted to compare single-dose pharmacokinetics of ethinyl estradiol in an oral contraceptive to steady-state values, and to assess whether any simpler measures could provide an adequate proxy of the ‘gold standard’ 24-hour steady-state area-under-the-curve. Identifying a simple, less expensive, measure of systemic ethinyl estradiol exposure would be useful for larger studies designed to assess the relationship between an individual’s ethinyl estradiol exposure and her side effects. Study Design We conducted a 13 samples over 24 hours pharmacokinetic analysis on day 1 and day 21 of the first cycle of a monophasic oral contraceptive containing 30 mcg ethinyl estradiol and 150 mcg levonorgestrel in 17 non-obese healthy white women. We also conducted an abbreviated single dose 9-sample pharmacokinetic analysis after a month washout. Ethinyl estradiol was measured by liquid chromatography-tandem mass spectrometry. We compared results of full 13-sample steady-state pharmacokinetic analysis with results calculated using fewer samples (9 or 5) and following the single doses. We calculated Pearson correlation coefficients to evaluate the relationships between these estimates of systemic ethinyl estradiol exposure. Results The area-under-the-curve, maximum (Cmax), and 24-hour (C24) values were similar following the two single oral contraceptive doses (area-under-the-curve, r = 0.92). The steady-state 13-sample 24-hour area-under-the-curve was highly correlated with the average 9-sample area-under-the-curve after the two single doses (r = 0.81, p = 0.0002). This correlation remained the same if the number of samples was reduced to 4, taken at time 1, 2.5, 4 and 24 hours. The C24 at steady-state was highly correlated with the 24-hour steady-state area-under-the-curve (r = 0.92, p < 0.0001). The average of the C24 values following the two single doses was also quite highly correlated with the steady-state area-under-the-curve (r = 0.72, p = 0

Various methods are currently used for the induction of labor. Nevertheless, the most effective method with the fewest side effects remains to be established. Misoprostol, administered vaginally, has been routinely used for this purpose; however, other forms of administration are being proposed, including the use of sublingual tablets. No studies have yet compared the effectiveness and safety of 12.5-μg misoprostol administered sublingually compared to a 25-μg vaginal dose of the drug for the induction of labor. A triple-blind, multicenter, placebo-controlled, randomized clinical trial will be conducted in Brazil at the Instituto de Medicina Integral Prof. Fernando Figueira and at the Assis Chateaubriand Maternity Teaching Hospital of the Federal University of Ceará. A total of 140 patients with full-term pregnancies, a live fetus, a Bishop score ≤ 6 and a recommendation of induction of labor will be randomized to one of two groups. One group will receive 12.5-μg sublingual tablets of misoprostol and placebo vaginal tablets, while the other group will receive placebo sublingual tablets and vaginal tablets containing 25 μg of misoprostol. The principal endpoint is the rate of tachysystole. The secondary endpoints are vaginal delivery within 24 h of induction, uterine hyperstimulation, Cesarean section, severe neonatal morbidity or perinatal death, severe maternal morbidity or maternal death, and maternal preference regarding the route of administration of the drug. Student's t-test, and the chi-square test of association or Fisher's exact test, as appropriate, will be used in the data analysis. Risk ratios and their respective 95% confidence intervals will be calculated. Misoprostol has been identified as a safe, inexpensive, easily administered option for the induction of labor, with satisfactory results. An experimental study has shown that misoprostol administered sublingually at a dose of 25 μg appears to be effective and is associated with

Cytotec (Misoprostol) is a prostaglandin E1 9(PgE1) analogue. Despite that it is not officially registered for obstetric and gynaecological targets, Cytotec (C) is widely used in this sphere. The author aims to study the effect and results from C application used for delivery (birth) induction, as well as means for cervical maturation. In order to reach this aim, beside the group of 45 pregnant women to who we applied C, we also reviewed the existing literature, which reported proves for C efficacy, pharma-kynetics and the safe aspects of its application (usage) in pregnancy. C was used with 45 pregnant women, divided in two groups: I group--27 pregnant women with oral application and II group--18 pregnant women with vaginal application. C was given per os in dosage 50 microg at 4 hours, the maximum dosage being 200 microg. When applied in the vagina, the dosage was twice 50 microg, every 6 hours. Four hours after the second dosage, if the effective delivery activity was not sufficient, we continued with sub-lingual application in dosage 50 microg every 4 hours till the regular delivery activity was reached. The vaginal delivery (childbirth) till the 24th hour of C application is considered as a successful induction. The delivery (childbirth) continuation, though with insignificant difference, is less under vaginal application. Uterine contractions begin (start) 30-35 minutes earlier under C application. Sectio Caesarea has smaller frequency under C application, in comparison with the general population frequency for the same period (year 2006 and the first half of 2007). The C induction is successful in 40 (88.89%), and with 7 (25.93%) the per oral application was prolonged via oxytocine infusion, and with half of the patients the vaginal application was continued via sun-lingual one. The author reaches the conclusion, that Cytotec is an effective and safe means for delivery (childbirth) induction, and that when dosage and application manner are set-up, the

The efficacy of lateral and escalation switch is a challenge in MS. We compared in a real-world setting the efficacy of switching to IFN beta-1a 44 mcg or to fingolimod in persons with relapsing remitting MS (pwRRMS) who failed with others injectable IFNs or glatiramer acetate. retrospective analysis of 24 months prospectively-collected data at the MS center of the University of Catania, Italy was performed. Patients who were switched to IFN-beta 1a 44 mcg or fingolimod were analyzed using propensity-score covariate adjustment model within demographic (e.g. age and gender) and disease (e.g. timing of pre-switch relapse) characteristics. Switching-time was considered the starting-time of the observation. 43 pwRRMS on IFN beta-1a 44 mcg and 49 pwRRMS on fingolimod were included. Baseline characteristics differed for EDSS score and number of T2 lesions (higher in group on fingolimod). At 24 months of follow up, both groups showed no differences in the survival curves of reaching a first new relapse, new T2 and Gd+ MRI brain lesions, even corrected for the propensity score covariate adjustment. lateral switch to IFN beta-1a 44 mcg and escalation switch to fingolimod showed same ability in influencing RRMS disease activity at 24 months.

We report on the NuSTAR observations of two bright Seyfert 1 galaxies, namely MCG +8-11-11 (100 ks) and NGC 6814 (150 ks). The main goal of these observations was to investigate the Comptonization mechanisms acting in the innermost regions of an active galactic nucleus (AGN) which are believed to be responsible for the UV/X-ray emission. The spectroscopic analysis of the NuSTAR spectra of these two sources revealed that although they had different properties overall (black hole masses, luminosity and Eddington ratios), they had very similar coronal properties. Both presented a power-law spectrum with a high-energy cut-off at ∼150-200 keV, a relativistically broadened Fe K α line and the associated disc reflection component, plus a narrow iron line likely emitted in Compton thin and distant matter. The intrinsic continuum was well described by Comptonization models that show for MCG +8-11-11 a temperature of the coronal plasma of kTe ∼ 60 keV and an extrapolated optical depth τ = 1.8; for NGC 6814, the coronal temperature was kTe ∼ 45 keV with an extrapolated optical depth of τ = 2.5. We compare and discuss these values to some most common Comptonization models that aim at explaining the energy production and stability of coronae in AGNs.

Background The study was conducted to examine the impact of oral contraceptives (OCs) on serum antimullerian hormone (AMH) levels by obesity status in reproductive-age women. Study design Ovulatory women, ages 18–35 years, of normal (< 25 kg/m2; n = 10) and obese (> 30 kg/m2; n = 10) body mass index (BMI) received a low-dose OC (20 mcg ethinyl estradiol/100 mcg levonorgestrel) for two cycles. Serum samples obtained at several time points during active pill use and hormone-free intervals were analyzed for AMH, FSH, LH, estradiol and inhibin B. Results AMH levels did not differ by OC cycle day in either BMI group. On average, AMH levels were 34% lower in the obese group (2.9±2.1 versus 4.4±1.8ng/ml, p<0.05). Modeling to determine differences in AMH throughout the cycle based on obesity status demonstrated significiantly lower levels (p<0.05), whereras serum AMH, FSH, LH, estradiol and inhibin B levels revealed no correlations when all time points were included. Conclusions In reproductive-aged women, serum AMH levels do not appear to fluctuate during OC use but AMH levels are significantly lower in obese women. Lower levels do not appear to be due to differences in gonadotropin levels or ovarian activity. PMID:20159182

Labor induction is indicated in 20% to 40% of pregnancies. Over half of pregnancies qualified for the induction of labor require stimulation of the cervix to ripen. The drug used increasingly more often in pre-induction is the PGE-1 pros-taglandin analog - misoprostol 200 μg. The study includes a total of 100 patients qualified for labor pre-induction with Misodel® (miso-prostol 200 μg vaginal insert). The study group comprises two subgroups: primigravidas and multiparas. Assessments included: indications for labor pre-induction, time from Misodel application to delivery, caesarean section rate and indica-tions, duration of first and second stage of labor, rate of vaginal deliveries, need for oxytocin or fenoterol administration side effects and newborn condition. The most common indication for labor induction was gestational diabetes and pregnancy past term. The average time to vaginal delivery was 14 h 45 min, time to the onset of active phase of labor - 11 h 45 min, time to membranes' rupture - 15 h, time to vaginal delivery - 14 h 18 min. The times of multiparas were significantly shorter. The rate of vaginal deliveries within 12 hours amounted to 42.42%, while within 24 hours it reached 83.33%. The overall caesarean section rate was 33%. The most common indication for caesarean section was the risk of intrauterine hypoxia. Tachysystole and hyperstimulation was observed in 4% of cases, while abnormalities in the cardiotocographic tracing in 43%. Misodel is an effective method for labor pre-induction, without affecting the caesarean section rate and has no adverse effect on the newborn condition.

Objective To determine if increasing the hormone dose or eliminating the hormone-free interval improves key pharmacokinetic (PK) alterations caused by obesity during oral contraceptive (OC) use. Study design Obese (BMI ≥ 30 kg/m2), ovulatory, otherwise healthy, women received an OC containing 20 mcg ethinyl estradiol (EE)/100 mcg levonorgestrel (LNG) dosed cyclically (21 days active pills with 7-day placebo week) for two cycles and then were randomized for two additional cycles to: Continuous Cycling [CC, a dose neutral arm using the same OC with no hormone-free interval] or Increased Dose [ID, a dose escalation arm using an OC containing 30 mcg EE/150 mcg LNG cyclically]. During Cycle 2, 3, and 4, outpatient visits were performed to assess maximum serum concentration (Cmax), area under the curve (AUC0-∞), and time to steady state as well as pharmacodynamics. These key PK parameters were calculated and compared within groups between baseline and treatment cycles. Results A total of 31 women enrolled and completed the study (CC group n = 16; ID group n = 15). Demographics were similar between groups [mean BMI: CC 38kg/m2 (SD 5.1), ID 41kg/m2 (SD 7.6)]. At baseline, the key LNG PK parameters were no different between groups; average time to reach steady-state was 12 days in both groups; Cmax were CC: 3.82 ± 1.28 ng/mL and ID: 3.13 ± 0.87 ng/mL; and AUC0-∞ were CC: 267 ± 115 hr*ng/mL and ID: 199±75 hr*ng/mL. Following randomization, the CC group maintained steady-state serum levels whereas the ID group had a significantly higher Cmax (p< 0.001) but again required 12 days to achieve steady-state. However, AUC was not significantly different between CC (412 ± 255 hr*ng/mL) and ID (283 ± 130 hr*ng/mL). Forty-five percent (14/31) of the study population had evidence of an active follicle-like structure prior to randomization and afterwards this decreased to 9% (3/31).

Update on oral contraception.

Oral contraceptives (OCs) were first introduced more than 30 years ago. OC manufacturers have reduced the dosage of synthetic estrogens (e.g., ethinyl estradiol, 100-150 mcg to 20-35 mcg) and progestins to limit their metabolic effects on lipoproteins, carbohydrates, and hemostasis. In addition to protection from pregnancy, OC benefits include lower incidence of painful periods, excessive bleeding, and iron deficiency anemia; reduction of ovarian cysts, benign breast tumors, and pelvic inflammatory disease; and protection against endometrial and ovarian cancers. The risk of a cardiovascular event (myocardial infarction, cerebrovascular events, venous thromboembolism, and deep vein thrombophlebitis) in OC users is 1-2/100,000 women years. Cardiovascular risk factors include smoking, hypertension, lipid disorders, severe obesity, diabetes mellitus, and cardiovascular events in first degree relatives before age 40. Thus, women with any of these risk factors should not use OCs. OCs do not increase the risk of breast cancer in women less than 59 years old. They may increase this risk if used over a long duration before the first fullterm pregnancy. OCs may cause a modest increase in cervical neoplasia. Low-dose OCs have a small effect on lipid metabolism. OCs increase serum triglycerides 30-50%. OCs increase insulin secretion and hyperinsulinemia increases the cardiovascular risk. Practitioners should evaluate clients before prescribing OCs. They should not prescribe OCs to women with hypertension, diabetes mellitus, lipid disorders, gynecological cancers, and previous cardiovascular disorders. Practitioners should tell clients that smoking is a leading risk factor and about OC's side effects (e.g., menstrual disturbances). The physical exam should include a cervical PAP smear, gynecological exam of the uterus and the ovaries, and a breast exam. Practitioners should test cholesterol and triglycerides before and during OC use. Premenopausal healthy women with no risk

We present near-infrared imaging and integral field spectroscopy of the centre of the dusty luminous infrared galaxy merger MCG+08-11-002, taken using the Near InfraRed Camera 2 (NIRC2) and the OH-Suppressing InfraRed Imaging Spectrograph (OSIRIS) on Keck II. We achieve a spatial resolution of ˜25 pc in the K band, allowing us to resolve 41 star clusters in the NIRC2 images. We calculate the ages of 22/25 star clusters within the OSIRIS field using the equivalent widths of the CO 2.3 μm absorption feature and the Br γ nebular emission line. The star cluster age distribution has a clear peak at ages ≲ 20 Myr, indicative of current starburst activity associated with the final coalescence of the progenitor galaxies. There is a possible second peak at ˜65 Myr which may be a product of the previous close passage of the galaxy nuclei. We fit single and double starburst models to the star cluster age distribution and use Monte Carlo sampling combined with two-sided Kolmogorov-Smirnov tests to calculate the probability that the observed data are drawn from each of the best-fitting distributions. There is a >90 per cent chance that the data are drawn from either a single or double starburst star formation history, but stochastic sampling prevents us from distinguishing between the two scenarios. Our analysis of MCG+08-11-002 indicates that star cluster age distributions provide valuable insights into the timelines of galaxy interactions and may therefore play an important role in the future development of precise merger stage classification systems.

An Extended Multi-Zone Model for the MCG-6-30-15 Warm Absorber

Morales, R.; Fabian, A. C.; Reynolds, C. S.

2000-01-01

The variable warm absorber seen with ASCA in the X-ray spectrum of MCG 6-30-15 shows complex time behaviour in which the optical depth of O VIII anticorrelates with the flux whereas that of O VII is unchanging. The explanation in terms of a two zone absorber has since been challenged by BeppoSAX observations. These present a more complicated behaviour for the O VII edge. The explanation we offer for both ASCA and BeppoSAX observations requires a very simple photoionization model together with the presence of a third, intermediate, zone and a period of very low luminosity. In practice warm absorbers are likely to be extended, multi-zone regions of which only part causes directly observable absorption edges at any given time depending on the value of the luminosity.

Considerable advances have been made in hormonal contraception in recent years, geared at maximizing compliance and minimizing discontinuation. In oral contraceptive (OC) formulations, the estrogenic component, generally ethinyl estradiol (EE), has been reduced significantly and newer progestins like dienogest and drospirenone (DRSP), compounds with different molecular structures, have been introduced; in addition, new regimens (extended, flexible, 24/4 formats instead of the standard 21/7 format) and innovative delivery systems (vaginal rings, transdermal patches, subcutaneous implants and intrauterine devices) are available. The multitude of choices allows hormonal contraception to be tailored to the individual woman in order to obtain non-contraceptive benefits, without significant side effects, and also a favorable risk/benefit profile for her general and reproductive health. Over the past few years, new OC formulations combining DRSP (3 mg), a unique progestin with both antimineralocorticoid and antiandrogenic activities, with estrogen (30 mcg or 20 mcg EE), in two regimens (24/4 and 21/7) of active pills in a 28-day cycle, have shown positive effects on water retention-related weight gain and physical, emotional and psychosexual well-being. It seems likely that the use of a low-dose, well-balanced OC and the shorter 4-day hormone-free interval may minimize the side effects that can impair quality of life and thus increase women's compliance with hormonal contraception therapy.

Are oral emergency contraceptives a safe and effective form of long-term birth control?

PubMed

Kraus, Connie; Hooper-Lane, Christopher

2017-10-01

Yes, but not as effective as some other methods. Annual pregnancy rates in women using pericoital levonorgestrel 150 mcg to 1 mg range from 4.9% to 8.9%; menstrual irregularity is the most common adverse effect (strength of recommendation [SOR]: B, Cochrane review of lower-quality trials). In women younger than 35 years who have sexual intercourse 6 or fewer times per month, correct and consistent use of pericoital levonorgestrel 1.5 mg results in an annual pregnancy rate of 11% (SOR: B, one large prospective, open-label trial). Pericoital contraception is less effective than long-acting reversible contraceptives (annual pregnancy rates of 0.05%-0.8%) or perfect use of combined oral contraceptives (0.3% annual pregnancy rate), but similar to, or better than, typical use of combined oral contraception (9%) and condoms (18%).

The stability of hydrocortisone in a commercially available dye-free oral vehicle was monitored to establish a beyond-use date for hydrocortisone oral suspension 2 mg/mL. Hydrocortisone oral suspension (2 mg/mL) was prepared from 10-mg tablets in a dye-free oral vehicle (Oral Mix, Medisca) and stored at 4°C and 25°C for 90 days in amber, plastic prescription bottles and oral syringes. The suspendability and dose repeatability of the oral suspension were evaluated. The solubility of hydrocortisone in the dye-free vehicle was determined. Over 90 days, pH and concentration of hydrocortisone in the oral suspension were measured. The stability-indicating nature of a high-pressure liquid chromatographic assay was evaluated in detail. The solubility of hydrocortisone in the dye-free vehicle was 230 mcg/mL at 25°C. This means that about 90% of the drug remains in the solid state where it is less susceptible to degradation. The preparation suspended well to support dose repeatability. The chromatographic assay resolved hydrocortisone from cortisone, excipients in the vehicle, and all degradation products. The assay passed United States Pharmacopeia system suitability tests. Hydrocortisone oral suspension (2 mg/mL) compounded using a dye-free, alcohol-free oral vehicle, Oral Mix, was stable in amber plastic bottles and syringes stored at 4°C and 25°C for 90 days within a 95% confidence interval.

Social networks and health policy: the case of misoprostol and the WHO model essential medicine list.

PubMed

Millard, Colin; Brhlikova, Petra; Pollock, Allyson

2015-05-01

The WHO Essential Medicines List (EML) was established to help countries prioritise medicines according to their health care needs. Selection for the List is based on rigorous scrutiny of public health relevance, evidence on efficacy and safety, and comparative cost effectiveness. The WHO ideal is that a medicine and its efficacy are based on science, but in reality a medicine has a social life and the acceptance of a pharmaceutical intervention involves the interaction of a wide array of governmental and civil society organisations, and industry. Misoprostol is a medicine widely used for both abortion and prevention of postpartum haemorrhage in low income countries. Although the evidence for the latter is highly contested it was nevertheless added to the WHO EML in 2011. We use social network analysis to examine the social, political and economic field surrounding the WHO EML applications and health policy. We describe a chronology of the drug's use and of the applications to the WHO EML and carry out a social network analysis of the organisations and individuals involved in the applications, research and dissemination. The research identified a network of 238 organisations and individuals involved in the promotion of misoprostol for postpartum haemorrhage and present at the time of the WHO EML applications. There is a strong interdependency between the funding bodies, civil society organisations, researchers and clinician organisations. The research was part of an EU FP7 funded project on Accessing Medicines in Africa and South Asia (2010-2013). Crown Copyright © 2015. Published by Elsevier Ltd. All rights reserved.

To evaluate the protective activity of allylpyrocatechol (APC), the major antioxidant constituent of Piper betel, against the indomethacin-induced stomach ulceration in the rat model and correlates with its antioxidative and mucin protecting properties. Male Sprague-Dawley rats were divided into five groups. Normal control rats (group I) were given the vehicle oral dose of gum acacia in distilled water (1 mL per rat); ulcerated control and treated rats (groups II-V) were given a single dose of indomethacin (30 mg/kg body wt.); group II rats were sacrificed 4 h after indomethacin administration; groups III-V rats were given the vehicle (1 mL per rat) or APC (2 mg/kg body wt.) or misoprostol (1.43 mug/kg body wt.) once daily by oral intubation for 7 d starting from 4 h after the indomethacin administration. After 7 d, the stomach tissues were excised for histological examination and biochemical analysis. Treatment with APC (2 mg/kg body wt per day) and misoprostol (1.43 mug/kg body wt per day) for 7 d could effectively heal the stomach ulceration as revealed from the ulcer index and histopathological studies. Compared to the zero day ulcerated group, treatment with APC and misoprostol reduced the ulcer index by 93.4% and 85.4% respectively (P < 0.05). Both APC and misoprostol accelerated ulcer healing observed in natural recovery (P < 0.05), their respective healing capacities not being significantly different. The healing capacities of APC and misoprostol could be attributed to their antioxidant activity as well as the ability to enhance the mucin content of the gastric tissues. Compared to the ulcerated untreated rats, those treated with APC and misoprostol showed near normal MDA levels, while the protein levels were 86% and 78% of the normal value respectively (P < 0.05). Likewise, both APC and misoprostol increased the SOD, catalase, and mucin levels significantly (P < 0.05), the effect of APC being better. APC can protect indomethacin-induced gastric ulceration

The Complex Soft X-ray Spectral Structure of MCG-6-30-15 and Mrk 766

The interpretation of the soft X-ray spectra of the Seyfert 1 galaxies, MCG-6-30-15 and Mrk 766, has remained controversial since high resolution data were first obtained with the grating instruments on Chandra and XMM-Newton, roughly one year ago. In an initial paper, Branduardi-Raymont et al. (2001), we argued that the RGS spectra of these two sources are inconsistent with simple warm absorber models, as has been invoked for Seyfert 1s in the past, but instead suggest the additional presence of relativistically broadened disk line features associated with the Lyα transitions of carbon, nitrogen, and oxygen. This conclusion was subsequently questioned by Lee et al. (2001), who contended that the Chandra HETG spectrum of MCG-6-30-15 is indeed well-described by the conventional warm absorber model, if one allows for the presence of dust in the warm absorbing medium. Here we reexamine the original RGS spectra in light of the Lee et al. (2001) criticisms. We first show that the explicit model presented by Lee et al. (2001) for MCG-6-30-15 is incompatible with the RGS data on this source, even if we allow both the continuum parameters and all of the absorbing column densities to be free parameters. That model over-predicts the ion{O}{VII} absorption line equivalent widths, and yields significant systematic residuals to the fits, especially at longer wavelengths, beyond the band covered by the HETG. We next show that the column densities of the oxygen ions (ion{O}{IV} through ion{O}{VIII}) are very well-constrained by the absorption line structure in the RGS data, and that, contrary to the assertion by Lee et al. (2001), the derived values are much too low to provide any significant contribution (either from line or continuum absorption) to the observed discrete jump in the spectra near 17.5 Å. Further, we show that the RGS spectra are also incompatible with the dust model presented by Lee et al. (2001). Specifically, the derived upper limit on the neutral oxygen

We conducted a cross-sectional survey of abortion facilities from professional networks in the United States (US, n = 703) and Canada (n = 94) to estimate the prevalence of medication abortion practices in these settings and to look at regional differences. Administrators responded to questions on gestational limits, while up to five clinicians per facility reported on 2012 medication abortion practice. At the time of fielding, mifepristone was not approved in Canada. 383 (54.5%) US and 78 (83.0%) Canadian facilities participated. In the US, 95.3% offered first trimester medication abortion compared to 25.6% in Canada. While 100% of providers were physicians in Canada, just under half (49.4%) were advanced practice clinicians in the US, which was more common in Eastern and Western states. All Canadian providers used misoprostol; 85.3% with methotrexate. 91.4% of US providers used 200 mg of mifepristone and 800 mcg of misoprostol, with 96.7% reporting home misoprostol administration. More than three-quarters of providers in both countries required an in-person follow-up visit, generally with ultrasound. 87.7% of US providers routinely prescribed antibiotics compared to 26.2% in Canada. Nonsteroidal anti-inflammatory drugs were the most commonly reported analgesic, with regional variation in opioid narcotic prescription. In conclusion, medication abortion practice follows evidence-based guidelines in the US and Canada. Efforts to update practice based on the latest evidence for reducing in-person visits and increasing provision by advanced practice clinicians could strengthen these services and reduce barriers to access. Research is needed on optimal antibiotic and analgesic use.

To compare bleeding patterns for 12 months continuous use of a contraceptive ring [contraceptive vaginal ring (CVR)] and pill [combined oral contraceptive (COC)] on a menstrually signaled regimen and the effectiveness of 4 days "treatment withdrawal" to stop bleeding. Women, 66 to each group, were randomized to continuous use of a CVR (15 mcg ethinyl estradiol/150 mcg etonogestrel) or a low-dose pill (20 mcg ethinyl estradiol/100 mcg levonorgestrel) for 360 days on a menstrually signaled regimen. Bleeding/spotting days, daily use of ring or pill, was recorded. Endpoint was the total number of bleeding/spotting days for each method over four 90-day reference periods (RP) plus the analysis of bleeding patterns using modified World Health Organization criteria. There was a reduction in the mean (±S.D.) number of bleeding/spotting days from RP1 (CVR 14.2±10; pill 16.6±10.9) to RP4 (CVR 8.8±9.6; pill 8.8±9.1). Fifteen percent of CVR and 4% COC users experienced amenorrhea or infrequent bleeding throughout the study. Amenorrhea increased over time (RP1 vs. RP4: CVR 10% vs. 21% and COC 2% vs. 30%). Compliance with the menstrually signaled regimen was poor. Ceasing hormones for 4 days stopped a bleeding episode within 5 days in the majority of episodes and many stopped spontaneously. Bleeding patterns with continuous use of the CVR and COC are similar and improve over 1 year of use. The unpredictability, but short duration, of bleeding episodes should be stressed during counseling. This information for clinicians and women about breakthrough bleeding patterns with use of a CVR or combined pill over 12 months using a menstrually signaled regimen will give women an indication of what to expect with continuous use.

XMM-Newton Reflection Grating Spectrometer (RGS) spectra of the Narrow Line Seyfert 1 galaxies MCG -6-30-15 and Mrk 766 are physically and spectroscopically inconsistent with standard models comprising a power-law continuum absorbed by either cold or ionized matter. We propose that the remarkably similar features detected in both objects in the 5 - 35 A band are H-like oxygen, nitrogen, and carbon emission lines, gravitation- ally redshifted and broadened by relativistic effects in the vicinity of a Kerr black hole. We discuss the implications of our interpretation, and demonstrate that the derived parameters can be physically self-consistent.

A comparison of the Abortion Rights Mobilization and Population Council trials.

We compared the published results of the 1994-1995 Population Council (PC) trial to those from the 1996-1997 Abortion Rights Mobilization (ARM) trial to determine whether 200 mg mifepristone with 800 micrograms vaginal misoprostol is more effective and has fewer side effects than 600 mg mifepristone with 400 micrograms oral misoprostol. The complete medical abortion rate was lower in the PC trial than the ARM trial: 92% compared with 97% up to 49 days LMP (p < 0.05) and 83% versus 96% from 50 to 56 days LMP (p < 0.05). Nausea and vomiting were reported more frequently in the PC trial. The overall acceptability of the procedure was lower in the PC trial (88%) than in the ARM trial (94%), (p < 0.05). Mifepristone can be reduced from 600 to 200 mg when followed by vaginal misoprostol without loss of efficacy. Vaginal misoprostol extends the efficacy to 56 days LMP and is associated with less nausea and vomiting. Home use of misoprostol is safe and acceptable to women and decreases the number of required visits from three to two in most cases.

To determine the efficacy of pre-emptive administration of the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen vs. a placebo on pain relief during medical abortion and to evaluate whether NSAIDs interfere with the action of misoprostol. Prospective, double-blind, randomized, controlled study. University-affiliated tertiary hospital. Sixty-one women who underwent first-trimester termination of pregnancy. Patients received 600 mg mifepristone orally, followed by 400 μg oral misoprostol 2 days later. They were randomized to receive pre-emptively two tablets of 400 mg ibuprofen orally or a placebo, when taking the misoprostol. The patients completed a questionnaire about side effects and pain score and returned for an ultrasound follow-up examination 10-14 days after the medical abortion. Significant pain, assessed by the need for additional analgesia, and failure rates, defined by a need for surgical intervention. Pre-emptive ibuprofen treatment was found to be more effective than a placebo in pain prevention, as determined by a significantly lower need for additional analgesia: 11 of 29 (38%) vs. 25 of 32 (78%), respectively. Treatment failure rate was not statistically different between the ibuprofen and placebo groups: 4 of 28 (14.2%) vs. 3 of 31 (9.7%), respectively. History of menstrual pain was predictive for the need of additional analgesia. Pre-emptive use of ibuprofen had a statistically significant beneficial effect on the need for pain relief during a mifepristone and misoprostol regimen for medical abortion. Ibuprofen did not adversely affect the outcome of medical abortion. NCT00997074. Copyright © 2012 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

Develop recommendations for the practice of induced abortion. The Pubmed database, the Cochrane Library and the recommendations from the French and foreign Gyn-Obs societies or colleges have been consulted. The number of induced abortions (IA) has been stable for several decades. There are a lot of factors explaining the choice of abortion when there is an unplanned pregnancy (UPP). Early initiation and choice of contraception in connection to the woman's life are associated with lower NSP. Reversible contraceptives of long duration of action should be positioned fist in line for the teenager because of its efficiency (grade C). Ultrasound before induced abortion must be encouraged but should not be obligatory before performing IA (Professional consensus). As soon as the sonographic apparition of the embryo, the estimated date of pregnancy is done by measuring the crown-rump length (CRL) or by measuring the biparietal diameter (BIP) from 11 weeks on (grade B). Reliability of these parameters being±5 days, IA could be done if measurements are respectively less than 90mm for CRL and less than 30mm for BIP (Professional consensus). A medical IA performed with a dose of 200mg mifepristone combined with misoprostol is effective at any gestational age (EL1). Before 7 weeks, mifepristone followed between 24 and 48hours by taking misoprostol orally, buccally sublingually or eventually vaginally at a dose of 400 ug possibly renewed after 3hours (EL1, grade A). Beyond 7 weeks, misoprostol given vaginally, sublingually or buccally are better tolerated with fewer side effects than oral route (EL1). It is recommended to always use a cervical preparation during an instrumental abortion (Professional consensus). Misoprostol is a first-line agent for cervical preparation at a dose of 400 mcg (grade A). Aspiration evacuation is preferable to curettage (grade B). A perforated uterus during an instrumental suction should not be considered as a scarred uterus (Professional

Effective treatment of chronic myelogenous leukemia (CML) largely depends on the eradication of CML leukemic stem cells (LSCs). We recently showed that CML LSCs depend on Tcf1 and Lef1 factors for self-renewal. Using a connectivity map, we identified prostaglandin E1 (PGE1) as a small molecule that partly elicited the gene expression changes in LSCs caused by Tcf1/Lef1 deficiency. Although it has little impact on normal hematopoiesis, we found that PGE1 treatment impaired the persistence and activity of LSCs in a pre-clinical murine CML model and a xenograft model of transplanted CML patient CD34 + stem/progenitor cells. Mechanistically, PGE1 acted on the EP4 receptor and repressed Fosb and Fos AP-1 factors in a β-catenin-independent manner. Misoprostol, an FDA-approved EP4 agonist, conferred similar protection against CML. These findings suggest that activation of this PGE1-EP4 pathway specifically targets CML LSCs and that the combination of PGE1/misoprostol with conventional tyrosine-kinase inhibitors could provide effective therapy for CML.

We examined the response of bone turnover markers and indices of energy status after 2 weeks of oral contraceptive (OC) therapy in premenopausal women with exercise-associated menstrual disturbances (EAMD). Six women with EAMD received one 28-day cycle of a triphasic OC containing 180-250 mcg norgestimate/25 mcg ethinyl estradiol (EAMD+OC) and six were controls (EAMD controls). Bone turnover markers amino-terminal propeptide of Type I procollagen and serum carboxy-terminal telopeptides of Type I collagen (PINP and SCTX-I) were assessed at baseline and after 2 weeks of OC therapy (EAMD+OC) or after a 30-day monitoring period (EAMD controls). Total triiodothyronine, resting energy expenditure (REE) and dietary intake were assessed as secondary end points. The absolute and percent changes from baseline in the primary and secondary outcomes were evaluated using an analysis of covariance, adjusting for baseline values of the corresponding outcome. Compared to EAMD controls, a significant change from baseline was observed in the EAMD+OC group for PINP (mean+/-SEM, 9.9+/-6.1 vs. -33.9+/-9.0 mcg/L; p=.005) and SCTX-I (-0.02+/-0.11 vs. -0.25+/-0.07 ng/mL; p=.017), but not osteoprotegerin (-0.53+/-0.22 vs. 0.20+/-0.44 pmol/L; p=.429) after 2 weeks (14.7+/-0.3 days) of OC therapy. Total triiodothyronine levels were elevated in the EAMD+OC group after therapy compared with EAMD controls (19.7+/-4.1 vs. -8.4+/-4.9 ng/dL; p=.002); however, no differences between groups were observed for the changes in REE or dietary intake. Our data demonstrate that 2 weeks of low-dose OC therapy rapidly reduced markers of bone resorption and formation, without any significant impact on energy status in women with EAMD.

AIM: To evaluate the protective activity of allylpyrocatechol (APC), the major antioxidant constituent of Piper betel, against the indomethacin-induced stomach ulceration in the rat model and correlates with its antioxidative and mucin protecting properties. METHODS: Male Sprague-Dawley rats were divided into five groups. Normal control rats (group I) were given the vehicle oral dose of gum acacia in distilled water (1 mL per rat); ulcerated control and treated rats (groups II-V) were given a single dose of indomethacin (30 mg/kg body wt.); group II rats were sacrificed 4 h after indomethacin administration; groups III-V rats were given the vehicle (1 mL per rat) or APC (2 mg/kg body wt.) or misoprostol (1.43 μg/kg body wt.) once daily by oral intubation for 7 d starting from 4 h after the indomethacin administration. After 7 d, the stomach tissues were excised for histological examination and biochemical analysis. RESULTS: Treatment with APC (2 mg/kg body wt per day) and misoprostol (1.43 μg/kg body wt per day) for 7 d could effectively heal the stomach ulceration as revealed from the ulcer index and histopathological studies. Compared to the zero day ulcerated group, treatment with APC and misoprostol reduced the ulcer index by 93.4% and 85.4% respectively (P < 0.05). Both APC and misoprostol accelerated ulcer healing observed in natural recovery (P < 0.05), their respective healing capacities not being significantly different. The healing capacities of APC and misoprostol could be attributed to their antioxidant activity as well as the ability to enhance the mucin content of the gastric tissues. Compared to the ulcerated untreated rats, those treated with APC and misoprostol showed near normal MDA levels, while the protein levels were 86% and 78% of the normal value respectively (P < 0.05). Likewise, both APC and misoprostol increased the SOD, catalase, and mucin levels significantly (P < 0.05), the effect of APC being better. CONCLUSION: APC can protect

To compare effectiveness and safety of dinoprostone, misoprostol and Cook's balloon as labour-inducing agents in women with intrauterine growth restriction (IUGR) at term. Retrospective cohort chart review of women diagnosed with foetal growth restriction at term in Reina Sofia Hospital, Cordoba, Spain from January 2014 to December 2015. Registration of baseline characteristics and method of induction was made. The main outcome was time from induction to delivery. Obstetric and perinatal outcomes were also collected. A total of 99 women were diagnosed with IUGR in the mentioned period. Of them, 21 women were induced with dinoprostone [dinoprostone group (DG)], 20 with misoprostol (MG) and in 58 with Cook's balloon (CG). Groups were homogeneous regarding pre-induction Bishop score and parity. The CG required more time (24.36 vs. 19.23 h; p = 0.02) and more oxytocin dose for conduction of labour from induction to delivery (6.75 vs. 1.24 mUI; p < 0.01) than DG. Moreover, the CG also needed more oxytocin than MG, 6.75 vs. 2.37 mUI (p < 0.001). Caesarean rate was 5, 14.9 and 17.3% in MG, DG and CG, respectively. No differences were observed in rates of uterine tachysystole, non-reassuring foetal status and neonatal adverse events. Prostaglandins were more effective than Cook's balloon to induce labour and achieve vaginal birth in this sample of women with IUGR at term, with a similar safety profile.

The study was conducted to investigate continuous daily levonorgestrel 90 mcg/ethinyl estradiol 20 mcg (LNG/EE) on premenstrual dysphoric disorder (PMDD). In this multicenter, randomized, double-blind, placebo-controlled study, women with PMDD received LNG/EE (n=186) or placebo (n=181) daily for 112 days and completed the Daily Record of Severity of Problems (DRSP). Mean DRSP change from baseline to late luteal phase was significantly greater with LNG/EE than placebo at the late luteal phase of the first estimated cycle (-30.52±1.73 [SE] vs. -22.47±1.77; p<.001) and the worst 5 days during the last on-therapy estimated cycle (-26.77±1.83 vs. -20.89±1.82; p=.016). Other primary end points were not statistically significant. Significantly more subject taking LNG/EE (52%) than placebo (40%) responded (≥50% improvement in the DRSP 7-day late luteal phase score and Clinical Global Impression of Severity score of ≥1 improvement) at last on-therapy cycle (p=.025). Continuous daily LNG 90 mcg/EE 20 mcg was well tolerated and may be useful for managing the physical, psychological and behavioral symptoms and loss of work productivity related to PMDD.

Background From 2001 to March 2006 Planned Parenthood health centers throughout the United States provided medical abortion by a regimen of oral mifepristone followed 24 to 48 hours later by vaginal misoprostol. In response to concerns about serious infections, in early 2006 Planned Parenthood changed the route of misoprostol administration to buccal and required either routine antibiotic coverage or universal screening and treatment for chlamydia; in July 2007, Planned Parenthood began requiring routine antibiotic coverage for all medical abortions. Methods We performed a retrospective analysis of Planned Parenthood cases assessing the rates of mortality caused by infection following medical abortion during a time period when misoprostol was administered vaginally (2001 through March 2006), as compared with the rate from April 2006 to the end of 2012 after a change to buccal administration of misoprostol and after initiation of new infection-reduction strategies. Results The mortality rate dropped significantly in the 81-month period after the joint change to 1) buccal misoprostol replacing vaginal misoprostol and 2) either sexually transmitted infection (STI) screening or routine preventative antibiotic coverage (15 month period) or universal routine preventative antibiotic coverage as part of the medical abortion (66 month period), from 1.37/100,000 to 0.00/100,000, p=0.013 (difference=1.37/100,000, 95% CI 0.47-4.03 per 100,000). Conclusion The infection-caused mortality rate following medical abortion declined by 100% following a change from vaginal to buccal administration of misoprostol combined with screen-and-treat or, far more commonly, routine antibiotic coverage.

This Phase 3, randomized, open-label, multicenter study conducted at 44 sites in Europe evaluated the safety and efficacy of a continuous, daily regimen of levonorgestrel (LNG) 90 mcg/ethinyl estradiol (EE) 20 mcg compared with a 21-day, cyclic LNG 100 mcg/EE 20 mcg regimen. Three hundred twenty-three healthy women were randomized to continuous LNG 90 mcg/EE 20 mcg and 318 subjects to cyclic LNG 100 mcg/EE 20 mcg for 1 year (13 pill packs). Pearl index, adverse event (AE) incidence and bleeding profiles were assessed. No pregnancies occurred with the continuous oral contraceptive (OC) (Pearl index=0.00). As the study progressed, the percentage of women who achieved amenorrhea during each 28-day pill pack increased: 40% at pill pack 7, 53% at pill pack 13. The percentage of women with no bleeding [with or without spotting (defined as not requiring sanitary protection)] was 50%, 69% and 79% at pill packs 3, 7 and 13, respectively. The incidence of AEs was similar to that of the cyclic OC (except for metrorrhagia and vaginal bleeding in the first 6 months). Continuous LNG 90 mcg/EE 20 mcg was shown to be a safe and effective OC in this direct comparison to a cyclic OC. Suppression of menses and the potential for no bleeding requiring sanitary protection may be provided by this continuous, low-dose OC.

To evaluate if letrozole-induced suppression of estradiol reduces progesterone receptor expression and apoptosis in the first-trimester placenta. We performed a double-blinded, randomized, placebo-controlled trial. We randomized 20 women requesting first-trimester abortion with gestation up to 63 days to receive either letrozole 10 mg daily or placebo pretreatment for 7 days before administrating 400 mcg of vaginal misoprostol followed by suction abortion. We collected the placental and decidual tissues on which we performed immunohistochemical staining for progesterone receptor and apoptotic markers (active caspase 3, caspase 3, Bcl2, CD95, fas ligand) and determined H-scores of each based on the intensities of staining. We performed terminal deoxynucleotidyl transferase-mediated dUTP-digoxigenin nick end labeling (TUNEL) assay for apoptosis in the samples of four women to confirm the findings from apoptotic markers. We excluded one woman in the letrozole group from the analysis because she had passage of abortus after taking letrozole, leaving 19 women (9 in the letrozole group, 10 in the placebo group) for analysis. There was no significant difference in the H-scorings of progesterone receptor and apoptotic markers, as well as proportion of apoptotic cells on TUNEL assay between the two groups. The H-scores for the progesterone receptor were 8.17 ± 2.67 (mean ± SD) in the letrozole group and 9.01 ± 2.82 in the placebo group (p=0.36). We did not detect a difference in the expression of progesterone receptor and apoptotic markers in placental and decidual tissues after letrozole pretreatment for 7 days in first-trimester abortion. We did not confirm the hypothesis that letrozole reduces progesterone receptor expression and induces apoptosis in the first-trimester placenta. Further studies are required to allow better understanding of the mechanism by which estrogen suppression following the use of letrozole can lead to improved abortion rate in the first

A prospective randomized trial was conducted to compare efficacy of a drospirenone-containing combined oral contraceptives (COC) with desogestrel-containing COC in women with polycystic ovary-syndrome (PCOS) not desirous of child-bearing. Sixty women were randomized into study group [ethinylestradiol (EE) 30 mcg+drospirenone 3 mg] and control group (EE 30 mcg+desogestrel 150 mcg), treated for 6 months and followed up at 1 month, 3 months, 6 months, during treatment and 3 and 6 months post-treatment. Acne and hirsutism scoring, bodyweight, body mass index (BMI), blood pressure (BP), ultrasound parameters, lipid profile, glycemic profile and hormonal profile were compared. Cycles were regular in both groups during treatment. Effect of regular cycles persisted in 44.83% (13/30) vs. 17.24% (5/30) in study vs. control group at 6 months post-treatment with 33.3% decreased hirsutism score in the study group (versus no change in control group) even at 6 months after stopping treatment. With treatment, BMI fell by 0.52 kg/m(2) in the study group; systolic and diastolic BP fell in the study group while it rose in the control group. Low-density lipoprotein significantly decreased and high-density lipoprotein was elevated in the study group (p<.05). The study group showed a significant fall in fasting/postprandial blood sugar and insulin and total testosterone against a rise in the control group. In women with PCOS, a drospirenone containing COC has better outcome in terms of persistent regular cycles, antiandrogenic effect, fall in BMI and BP, better lipid profile, favorable glycemic and hormonal profile than desogestrel-containing COC.

The aim of the present study was to explore central and peripheral host responses to an anorexia-cachexia producing tumor. We focused on neuroendocrine anorexigenic signals in the hypothalamus, brainstem, pituitary and from the tumor per se. Expression of mRNA for corticotropin-releasing hormone (CRH), cocaine- and amphetamine-regulated transcript (CART), nesfatin-1, thyrotropin (TSH) and the TSH receptor were explored. In addition, we examined changes in plasma TSH, CART peptides (CARTp) and serum amyloid P component (SAP). C57BL/6 mice were implanted with MCG101 tumors or sham-treated. A sham-implanted, pair‑fed (PF) group was included to delineate between primary tumor and secondary effects from reduced feeding. Food intake and body weight were measured daily. mRNA levels from microdissected mouse brain samples were assayed using qPCR, and plasma levels were determined using ELISA. MCG101 tumors expectedly induced anorexia and loss of body weight. Tumor-bearing (TB) mice exhibited an increase in nesfatin-1 mRNA as well as a decrease in CART mRNA in the paraventricular area (PVN). The CART mRNA response was secondary to reduced caloric intake whereas nesfatin-1 mRNA appeared to be tumor-specifically induced. In the pituitary, CART and TSH mRNA were upregulated in the TB and PF animals compared to the freely fed controls. Plasma levels for CARTp were significantly elevated in TB but not PF mice whereas levels of TSH were unaffected. The plasma CARTp response was correlated to the degree of inflammation represented by SAP. The increase in nesfatin-1 mRNA in the PVN highlights nesfatin-1 as a plausible candidate for causing tumor-induced anorexia. CART mRNA expression in the PVN is likely an adaptation to reduced caloric intake secondary to a cancer anorexia-cachexia syndrome (CACS)‑inducing tumor. The MCG101 tumor did not express CART mRNA, thus the elevation of plasma CARTp is host derived and likely driven by inflammation.

To determine the efficacy of a nonsteroidal anti-inflammatory drug vs. paracetamol in pain relief during medical abortion and to evaluate whether nonsteroidal anti-inflammatory drugs interfere with the action of misoprostol. A prospective double-blind controlled study. University-affiliated tertiary hospital. One hundred twenty women who underwent first-trimester termination of pregnancy. Patients received 600 mg mifepristone orally, followed by 400 microg of oral misoprostol 2 days later. They were randomized to receive ibuprofen or paracetamol when pain relief was necessary. Patients completed a questionnaire about side effects and pain score and returned for an ultrasound follow-up examination 10-14 days after medical abortion. Success rates, as defined by no surgical intervention, and pain scores were assessed. Ibuprofen was found to be statistically significantly more effective for pain relief after medical abortion compared with paracetamol. There was no difference in the failure rate of medical abortion, and the frequency of surgical intervention was slightly higher in the group that received paracetamol (16.3% vs. 8.5%). Ibuprofen was found to be more effective than paracetamol for pain reduction during medical abortion. A history of surgical or medical abortion was predictive for high pain scores. Despite its anti-prostaglandin effects, ibuprofen use did not interfere with the action of misoprostol.

Study Objective To determine whether bone mineral density (BMD) is lower in hormonal contraceptive users than that in an untreated, comparison group. Design Observational, prospective cohort; duration: 24 months. Setting Adolescent clinics in a midwestern, metropolitan setting. Patients 433 postmenarcheal girls, aged 12–18 years, on depot medroxyprogesterone acetate (DMPA) [n=58], oral contraceptives (OC) [n=187], or untreated (n=188). Intervention DMPA and OC containing 100 mcg levonorgestrel and 20 mcg ethinyl estradiol. Main Outcome Measure BMD measurements at spine and femoral neck were obtained with dual x-ray absorptiometry (DXA) at baseline and 6-month intervals. Results Over 24 months, mean percent change in spine BMD was: DMPA −1.5%, OC +4.2%, and untreated +6.3%. Mean percent change in femoral neck BMD was: DMPA −5.2%, OC +3.0%, untreated +3.8%. Statistical significance was found between the DMPA group and other two groups (p<.001). In the DMPA group, mean percent change in spine BMD over the first 12 months was −1.4%; the rate of change slowed to −0.1% over the second 12 months. No bone density loss reached the level of osteopenia. Conclusions Adolescent girls receiving DMPA had significant loss in BMD compared with bone gain in the OC and untreated group. However, its clinical significance is mitigated by slowed loss after the first year of DMPA use and general maintenance of bone density values within the normal range. PMID:18222431

Objectives The risk of venous thromboembolism (VTE) is highest during the initial months of oral contraceptive (OC) use. We sought to evaluate the extent of hemostatic variable changes during the initial OC cycle and if such changes are related to systemic ethinyl estradiol (EE2) exposure. Study Design Participants provided multiple blood samples during a 21-day OC cycle (30 mcg EE2; 150 mcg levonorgestrel) and after a single dose following a wash-out period. Analytes included D-dimer, factor VIII activity, protein C total antigen and the hepatic proteins corticosteroid- and sex-hormone-binding globulins (CBG and SHBG). EE2 pharmacokinetic analyses related to the 24 hours after the first OC tablet (OC1) and at steady state (OC21). Results Seventeen women completed the study. D-dimer more than doubled by OC6 (p = 0.013) and remained elevated at OC21 (p=0.012). D-dimer levels within women varied widely from day-to-day. Factor VIII increased 27% by OC2 (p < 0.001), but declined to a 9% increase by OC21. Protein C increased only 6%. EE2 steady-state area-under-the-curve ranged from 488 to 1103 pg·h/mL; higher levels were not correlated with greater increases in clotting variables. CBG and SHBG increased significantly, but were not significantly correlated with levels of EE2 or with the hemostatic variables. Conclusions D-dimer increases during the first OC cycle were at least as great as increases seen with longer OC use. These results provide support for the increased VTE risk during initial OC use. The extreme variability in D-dimer levels may be an important component of this risk. PMID:26452328

Unscheduled bleeding is the main side effect of continuous oral contraceptive pills (OCPs) and has been correlated with the up-regulation of matrix metalloprotineases (MMPs). The study objective was to determine if prophylactic administration of doxycycline (an MMP inhibitor at low subantimicrobial doses) would prevent unscheduled bleeding during the initiation of a continuous OCP. Subjects using cyclic hormonal contraceptives (combined OCPs, patch or ring) without unscheduled bleeding were switched to continuous OCPs (20 mcg ethinyl estradiol/100 mcg levonorgestrel). They were randomized to receive daily doxycycline [sustained-release subantimicrobial dose (40 mg daily)] or placebo for the first 84 days and then observed for an additional 28 days on the continuous OCP alone. The number of bleeding/spotting days and the time in days it took to achieve amenorrhea were compared using a t test. Sixty-five subjects were randomized. Although the use of doxycycline did not significantly decrease the number of mean bleeding/spotting days in the first 84 days of the study [doxycycline 14.75 (SE 2.30), placebo 17.78 (2.31), p=.36], women who received doxycycline had a significantly earlier onset of amenorrhea [mean last day of bleeding/spotting doxycycline 61.7 (7.7), placebo 85.2 (6.7), p=.03]. The coadministration of subantimicrobial-dose doxycycline during initiation of continuous OCPs results in a significant reduction in the length of time needed to achieve amenorrhea.

The gold standard for measuring oral contraceptive (OC) pharmacokinetics is the 24-h steady-state area under the curve (AUC). We conducted this study to assess whether limited sampling at steady state or measurements following use of one or two OCs could provide an adequate proxy in epidemiological studies for the progestin 24-h steady-state AUC of a particular OC. We conducted a 13-sample, 24-h pharmacokinetic study on both day 1 and day 21 of the first cycle of a monophasic OC containing 30-mcg ethinyl estradiol and 150-mcg levonorgestrel (LNG) in 17 normal-weight healthy White women and a single-dose 9-sample study of the same OC after a 1-month washout. We compared the 13-sample steady-state results with several steady-state and single-dose results calculated using parsimonious sampling schemes. The 13-sample steady-state 24-h LNG AUC was highly correlated with the steady-state 24-h trough value [r=0.95; 95% confidence interval (0.85, 0.98)] and with the steady-state 6-, 8-, 12- and 16-h values (0.92≤r≤0.95). The trough values after one or two doses were moderately correlated with the steady-state 24-h AUC value [r=0.70; 95% CI (0.27, 0.90) and 0.77; 95% CI (0.40, 0.92), respectively]. Single time-point concentrations at steady state and after administration of one or two OCs gave highly to moderately correlated estimates of steady-state LNG AUC. Using such measures could facilitate prospective pharmaco-epidemiologic studies of the OC and its side effects. A single time-point LNG concentration at steady state is an excellent proxy for complete and resource-intensive steady-state AUC measurement. The trough level after two single doses is a fair proxy for steady-state AUC. These results provide practical tools to facilitate large studies to investigate the relationship between systemic LNG exposure and side effects in a real-life setting. Copyright © 2017 Elsevier Inc.

[Potential advantages of triphasic combined oral contraceptives in the light of recent epidemiological and endocrinometabolic data].

Gaspard, U; Dubois, M

1982-09-01

New epidemiologic data on the vascular risks of oral contraceptives (OCs) were assessed to determine whether the recently introduced low dose triphasic pills offer greater potential safety for OC users than previous formulations. Epidemiologic studies have demonstrated that vascular accidents are less frequent with OCs containing lower doses of both estrogens and progestins. The new triphasic pills have the lowest steroid content of any pills yet developed and less of a progestin climate than low dose monophasic pills. The gradual increases in the progestin dose, from 50 mcg on days 1-6 to 75 mcg on days 7-11 and 125 mcg on days 12-21 and of ethinyl estradiol from 30 mcg on days 1-6 to 40 on days 7-11 and back to 30 on days 12-21 reflect the natural cycle of steroid secretion. The endometrial mucus is better developed than under low dose monophasic pills, permitting better cycle control. Triphasic pills have been shown in all studies to block secretion by the hypothalamus and pituitary of the gonadotropins follicle stimulating hormone and luteinizing hormone, resulting in absence of follicular maturation and of ovulation. Even with the small dose of levonorgestrel, the cervical mucus is rendered inhospitable to capacitation and passage of sperm. The impact on glucose tolerance of low doses of ethinyl estradiol, even after long use, is minimal, but the 19 norsteroids used in most combined pills have a more significant impact. To the directly stimulating effect of progestins on pancreatic insulin secretion is added the development of increased peripheral resistence apparently due to a decrease in the number of insulin receptors in the target tissue. The decrease appears to be dose dependent and proportional to the androgenicity of the progestin. A recent study indicated that triphasic pills caused less of a deterioration in glucose tolerance than standard or low-dose combined OCs or a biphasic formulation. This finding was significant because of the possibility that

Objective To compare the effectiveness, in terms of complete abortion, of the World Health Organization (WHO)- and the China-recommended protocol for first-trimester medical abortion. Methods A retrospective analysis of clinical data from women presenting for first trimester medical abortion between January 2009 and August 2010 at reproductive health clinics in Qingdao, Xi’an, Nanjing, Nanning, and Zhengzhou was conducted. One clinic in Qingdao administered the WHO-recommended protocol (200 mg mifepristone orally followed by 0.8 mg misoprostol buccally 36–48 hours later). Four clinics in the other locations provided the China-recommended procedure (Day 1: 50 mg of mifepristone in the morning, 25 mg in the afternoon; Day 2: 50 mg of mifepristone in the morning, 25 mg in the afternoon; Day 3: 0.6 mg oral misoprostol). Data on reproductive and demographic characteristics were extracted from clinic records, and complete termination was determined on day 14 (post-mifepristone administration). Results A total of 337 women underwent early medical abortion (167 WHO- and 170 China-recommended procedures). Complete abortion was significantly higher among women who had the WHO protocol than those who received the China protocol (91.0% vs 77.7%, respectively; P < 0.001). Women using the China-recommended protocol were three times more likely to require an additional dose of misoprostol than women using the WHO protocol (21.8% vs 7.8%, respectively; P < 0.001), and had significantly more bleeding on the day of misoprostol administration (12.5 mL vs 18.5 mL; P < 0.001). Conclusion This clinical audit provides preliminary evidence suggesting the WHO-recommended protocol may be more effective than the China-recommended protocol for early medical abortion. A larger scale study is necessary to compare the methods’ effectiveness and acceptability. PMID:22505831

To compare the effectiveness, in terms of complete abortion, of the World Health Organization (WHO)- and the China-recommended protocol for first-trimester medical abortion. A retrospective analysis of clinical data from women presenting for first trimester medical abortion between January 2009 and August 2010 at reproductive health clinics in Qingdao, Xi'an, Nanjing, Nanning, and Zhengzhou was conducted. One clinic in Qingdao administered the WHO-recommended protocol (200 mg mifepristone orally followed by 0.8 mg misoprostol buccally 36-48 hours later). Four clinics in the other locations provided the China-recommended procedure (Day 1: 50 mg of mifepristone in the morning, 25 mg in the afternoon; Day 2: 50 mg of mifepristone in the morning, 25 mg in the afternoon; Day 3: 0.6 mg oral misoprostol). Data on reproductive and demographic characteristics were extracted from clinic records, and complete termination was determined on day 14 (post-mifepristone administration). A total of 337 women underwent early medical abortion (167 WHO- and 170 China-recommended procedures). Complete abortion was significantly higher among women who had the WHO protocol than those who received the China protocol (91.0% vs 77.7%, respectively; P < 0.001). Women using the China-recommended protocol were three times more likely to require an additional dose of misoprostol than women using the WHO protocol (21.8% vs 7.8%, respectively; P < 0.001), and had significantly more bleeding on the day of misoprostol administration (12.5 mL vs 18.5 mL; P < 0.001). This clinical audit provides preliminary evidence suggesting the WHO-recommended protocol may be more effective than the China-recommended protocol for early medical abortion. A larger scale study is necessary to compare the methods' effectiveness and acceptability.

Purpose Using sputum neutrophils as the primary measure, and other inflammation biomarkers, this study evaluated the anti-inflammatory effects of the combination salmeterol 50 mcg and fluticasone propionate 250 mcg (SFC 250) in Japanese patients with chronic obstructive pulmonary disease (COPD). Patients and methods Patients were treated in a randomized, double-blind, parallel group, placebo-controlled trial with SFC 250 twice daily (n=26) or placebo (n=26) for 12 weeks. At the start and end of treatment, inflammation biomarkers (sputum and serum), lung function, and health status (COPD Assessment Test [CAT] questionnaire) were measured. Results Although a numerical decrease in differential neutrophil count was observed from baseline, SFC 250 did not significantly reduce sputum neutrophils compared with placebo, nor were there significant changes from baseline in the other biomarkers (sputum or serum), lung function, or CAT, versus placebo. Squamous epithelial cell contamination in some sputum samples rendered them unacceptable for analysis, which reduced the sample size to n=19 (SFC 250) and n=10 (placebo). However, inclusion of contaminated samples did not affect the overall trend of the outcome. Ad hoc bootstrap statistical analysis showed a 27.9% (SFC 250) and 1.3% (placebo) decrease in sputum neutrophils. Sputum IL-8 decreased by 43.2% after SFC 250 but increased by 48.3% with placebo. Responder analyses showed 42% of patients had ≥20% decrease in neutrophils from baseline; and 47% of patients had a ≥200 pg/mL change in sputum IL-8 following SFC 250 versus 20% after placebo; both changes are considered clinically relevant. Conclusion This study provides additional information about inflammation in Japanese COPD patients and is the first to study the anti-inflammatory effects of SFC 250 in this context and population. In the primary analysis, SFC 250 did not produce significant changes from baseline in sputum neutrophil levels or other sputum or serum

To investigate whether the administration of an oral contraceptive containing the new antiandrogenic drospirenone is associated with reduced adrenal androgen synthesis in hyperandrogenic women with diagnosis of polycystic ovary syndrome. Drospirenone, an analogue of spironolactone and aldosterone antagonist, is a novel progestin under clinical development that is similar to the natural hormone progesterone, combining potent progestogenic with antimineralocorticoid and antiandrogenic activities. Prospective study. Healthy volunteers in University Department of Obstetrics and Gynecology. Fifteen women ages 18 to 28 years with the diagnosis of polycystic ovary syndrome. Three months of contraceptive use (30 mcg ethinylestradiol, 3 mg drospirenone). An adrenocorticotropic hormone test was performed before and after the study. Adrenal production of cortisol was unchanged after therapy with oral contraceptives. An interesting observation was reduced basal concentrations of androgens such as androstenedione, dehydroepiandrosterone sulfate, testosterone, and free testosterone during therapy. The ratios of the areas of substrates to products before and after oral contraceptive administration were compared for differences in 17alpha-hydroxylase (17-hydroxyprogesterone/progesterone) and 17,20-lyase (androstenedione/17-hydroxyprogesterone); activities were significantly reduced, indicating a reduction in the activities of these enzymes. The present results show for the first time that oral contraceptives containing drospirenone affect adrenal steroidogenesis by reducing synthesis and release of androgens in response to adrenocorticotropic hormone, leaving adrenal production of cortisol unchanged.

To evaluate whether oral contraceptive pill (OCP) therapy has any effects on ovarian stromal blood flow by using pulsed and color Doppler at the end of 3 months follow-up period of OCP-users and non-users with or without polycystic ovary syndrome (PCOS). 200 patients were included in the study. The patients were designed into four groups as follows; Group 1: PCOS patients that received OCP containing 30 mcg ethinyl estradiol (EE) plus 3mg drospirenone for 3 months (DRP n=50); Group 2: PCOS patients that received no medication (n=50); Group 3: Healthy controls that received OCP (EE plus DRP) (n=50); Group 4: healthy controls that received no medication (n=50). Resistance index (RI) and pulsatility index (PI) of both ovarian arteries, hormonal, anthropometric and biochemical parameters were assessed before and after 3 months. There was a significant increament in RI and PI of both ovarian arteries in healthy controls (Group 3) and in women with PCOS (Group 1) who received OCP (p<0.001). The increment rate in both Doppler parameters were significantly higher in women with PCOS (Group 1) than healthy controls (Group 3) (p<0.001). Whereas RI and PI values of both ovaries remained unchanged in all untreated women with or without PCOS (Groups 2 and 4). OCP therapy reduced ovarian vascularization in both PCOS and healthy users after 3 months of therapy and this decrease is especially noticeable in women with PCOS.

Pain is often cited as one of the worst features of medical abortion. Further, inadequate pain management may motivate some women to seek unnecessary clinical care. There is a need to identify effective methods for pain control in this setting. We propose a randomized, placebo-controlled trial. 576 participants (288 nulliparous; 288 parous) from study sites in Nepal, South Africa and Vietnam will be randomly allocated to one of three treatments: (1) ibuprofen 400 mg PO and metoclopramide 10 mg PO; (2) tramadol 50 mg PO and a placebo; or (3) two placebo pills, to be taken immediately before misoprostol and repeated once four hours later. All women will be provided with supplementary analgesia for use as needed during the medical abortion. We hypothesize that women receiving prophylactic analgesia will report lower maximal pain scores in the first 8 h following misoprostol administration compared to women receiving placebos for medical abortion through 63 days' gestation. Our primary objective is to determine whether prophylactic administration of ibuprofen and metoclopramide or tramadol provides superior pain relief compared to analgesia administration after pain begins, measured during the first eight hours after misoprostol administration. Secondary objectives include identifying covariates associated with higher reported pain scores; determining any impact of the study medicines on medical abortion success; and, qualitatively exploring women's physical experiences of medical abortion, especially related to pain, and how can they be improved. Data sources include medical records, participant symptom diaries and interview data obtained on the day of enrollment, during the medical abortion, and at follow-up. Participants will be contacted via telephone on day 3 and return for follow-up will occur approximately 14 days after mifepristone, concluding study participation. A subset of 42 women will also be invited to undergo in-depth qualitative interviews following

Objective To evaluate the effects of a commonly used combined hormonal oral contraceptive (OC) on carbohydrate metabolism in obese as compared with obese women. Design 6-month prospective study. Setting Clinical Research Center at an academic medical center. Patients Premenopausal non-diabetic women with BMI < 25 kg/m2 (n=15) or > 30 kg/m2 (n=14). Intervention Ethinyl estradiol 35mcg and norgestimate 0.18/0.215/0.25 mg for 6 cycles. Main Outcome Measures Insulin sensitivity (Si) by frequent sampling intravenous glucose tolerance test; other indices of insulin sensitivity (ISI HOMA, Matsuda index); fasting lipid panel. Results Si changed from 6.62±3.69 min−1/mu/L (baseline) to 8.23±3.30 min−1/mu/L (6 months) in lean women, and from 4.36±2.32 to 3.82±2.32 min−1/mu/L in obese women (p for interaction=0.0494). Divergent effects on insulin sensitivity were also observed with ISI HOMA (p=0.0128) and Matsuda index (p=0.0227). LDL increased by approximately 20 mg/dL in both groups (p<0.005 [lean]; p<0.01 [obese]). Conclusions Lean and obese women exhibit differential changes in insulin sensitivity when given 6 months of a commonly used OC. The mechanisms of these differences, and whether these divergent effects persist long-term, require further investigations. Capsule Lean and obese non-diabetic women exhibit differential changes in insulin sensitivity when given 6 months of a commonly used OC (ethinyl estradiol 35mcg and norgestimate 0.18/0.215/0.25 mg) PMID:21676394

We aimed to find the optimal route of iron supplementation in patients with malignancy and iron deficiency (true or functional) anemia not receiving erythropoiesis stimulating agents (ESA). Adult patients with malignancy requiring chemotherapy, hemoglobin (Hb) <12 g/dL and serum ferritin <100 mcg/mL, transferrin saturation <20% or hypochromic red blood cells >10% were randomized to intravenous (IV) iron sucrose or oral ferrous sulfate. The primary endpoint was change in Hb from baseline to 6 weeks. Secondary endpoints included blood transfusion, quality of life (QoL), toxicity, response and overall survival. A total of 192 patients were enrolled over 5 years: 98 on IV arm and 94 on oral arm. Median age was 51 years; over 95% patients had solid tumors. The mean absolute increase in Hb at 6 weeks was 0.11 g/dL (standard deviation [SD]: 1.48) in IV arm and -0.16 g/dL (SD: 1.36) in oral arm, P = 0.23. Twenty-three percent patients on IV iron and 18% patients on oral iron had a rise in Hb of ≥1 g/dL at 6 weeks, P = 0.45. Thirteen patients (13.3%) on the IV iron arm and 14 patients (14.9%) on the oral arm required blood transfusion, P = 1.0. Gastrointestinal toxicity (any grade) developed in 41% patients on IV iron and 44% patients on oral iron, P = 1.0. 5 patients on IV iron and none on oral iron had hypersensitivity, P = 0.06. QoL was not significantly different between the two arms. IV iron was not superior to oral iron in patients with malignancy on chemotherapy and iron deficiency anemia. © 2017 John Wiley & Sons Australia, Ltd.

Background Combined oral contraceptive (COC) use is the most commonly used reversible method of birth control. The incorrect use of COCs is frequent and one of the most common causes of unintended pregnancies. Community pharmacists (CPs) are in a strategic position to improve COC use because they are the last health professional to interact with patients before drug use. Objective To evaluate the COC dispensing practices of CPs in a developing country. Method A cross-sectional study was conducted in community pharmacies of Assis and Ourinhos microregions, Brazil, between June 1, 2012, and October 30, 2012. Four simulated patients (SPs) (with counseled audio recording) visited community pharmacies with a prescription for Ciclo 21® (a COC containing ethinyl estradiol 30 mcg + levonorgestrel 15 mcg). The audio recording of every SP visit was listened to independently by 3 researchers to evaluate the COC dispensing practice. The percentage of CPs who performed a screening for safe use of COCs (i.e., taking of patients’ medical and family history, and measuring of blood pressure) and provided counseling, as well as the quality of the screening and counseling, were evaluated. Results Of the 185 CPs contacted, 41 (22.2%) agreed to participate in the study and finished the study protocol. Only 3 CPs asked the SP a question (1 question asked by each professional), and all of the questions were closed-ended, viz., “do you smoke?” (n = 2) and “what is your age?” (n = 1). None of the CPs measured the patient’s blood pressure. Six CPs provided counseling when dispensing COCs (drug dosing, 5 CPs; possible adverse effects, 2 CPs), and one CP provided counseling regarding both aspects. Conclusion The CPs evaluated did not dispense COC appropriately and could influence in the occurrence of negatives therapeutic outcomes such as adverse effects and treatment failure. PMID:24324584

Measurements of the high-energy cut-off in the coronal continuum of active galactic nuclei have long been elusive for all but a small number of the brightest examples. We present a direct measurement of the cut-off energy in the nuclear continuum of the nearby Seyfert 1.9 galaxy MCG-05-23-016 with unprecedented precision. The high sensitivity of NuSTAR up to 79 keV allows us to clearly disentangle the spectral curvature of the primary continuum from that of its reflection component. Using a simple phenomenological model for the hard X-ray spectrum, we constrain the cut-off energy to 116{sub −5}{sup +6} keV with 90% confidence.more » Testing for more complex models and nuisance parameters that could potentially influence the measurement, we find that the cut-off is detected robustly. We further use simple Comptonized plasma models to provide independent constraints for both the kinetic temperature of the electrons in the corona and its optical depth. At the 90% confidence level, we find kT{sub e} = 29 ± 2 keV and τ {sub e} = 1.23 ± 0.08 assuming a slab (disk-like) geometry, and kT{sub e} = 25 ± 2 keV and τ {sub e} = 3.5 ± 0.2 assuming a spherical geometry. Both geometries are found to fit the data equally well and their two principal physical parameters are correlated in both cases. With the optical depth in the τ {sub e} ≳ 1 regime, the data are pushing the currently available theoretical models of the Comptonized plasma to the limits of their validity. Since the spectral features and variability arising from the inner accretion disk have been observed previously in MCG-05-23-016, the inferred high optical depth implies that a spherical or disk-like corona cannot be homogeneous.« less

MCG-5-23-16 is one of the first active galactic nuclei (AGNs) where relativistic reverberation in the iron K line originating in the vicinity of the supermassive black hole was found, based on a short XMM-Newton observation. In this work, we present the results from long X-ray observations using Suzaku, XMM-Newton, and NuSTAR designed to map the emission region using X-ray reverberation. A relativistic iron line is detected in the lag spectra on three different timescales, allowing the emission from different regions around the black hole to be separated. Using NuSTAR coverage of energies above 10 keV reveals a lag between these energies and the primary continuum, which is detected for the first time in an AGN. This lag is a result of the Compton reflection hump responding to changes in the primary source in a manner similar to the response of the relativistic iron K line.

Functional iron deficiency (FID) is a major cause of persistent anemia in dialysis patients and also contributes to a suboptimal response to erythropoietin (Epo) administration. Vitamin C acts as an enzyme cofactor and enhances mobilization of the ferrous form of iron to transferrin thus increasing its bioavailability. High-dose intravenous vitamin C has been shown to decrease the Epo requirement and improve hemoglobin levels in previous studies. This study assessed the effect of low-dose oral vitamin C on possible reduction in Epo dose requirements in stable hemodialysis patients with FID. This prospective study included 22 stable hemodialysis patients with FID defined as transferrin saturation (T sat) <30 % and ferritin levels of >100 mcg/L with Epo requirement of ≥4000 U/HD session. Patients received oral vitamin C 250 mg daily for 3 months. Hemoglobin, iron and T sat levels were recorded monthly. No one received iron supplementation during the study period. There was a significant reduction in median Epo dose requirement in the 15 patients who completed the study, from 203.1 U/kg/week (95 % CI 188.4-270.6) to 172.8 U/kg/week (95 % CI 160.2-214.8), (P = 0.01). In the seven responders, there was 33 % reduction in Epo dose from their baseline. Despite adjustment of Epo dose, the mean hemoglobin level was significantly increased from 10.1 ± 0.6 to 10.7 ± 0.6 mg/dL (P = 0.03). No adverse effects of oral vitamin C were observed. Daily low-dose oral vitamin C supplementation reduced Epo dose requirements in hemodialysis patients with FID. Limitations of this study include a small sample size and the lack of measurements of vitamin C and oxalate levels. Despite concerns regarding oral vitamin C absorption in dialysis patients, this study indicates vitamin C was well tolerated by all participants without reported adverse effect.

Gestational diabetes mellitus (GDM) potentially harms the child before birth. We previously found GDM to be associated with developmental changes in the central nervous system. We now hypothesise that GDM may also impact on the fetal autonomic nervous system under metabolic stress like an oral glucose tolerance test (OGTT). We measured heart rate variability (HRV) of mothers and fetuses during a three-point OGTT using fetal magnetocardiography (fMCG). Measurements were performed in the fMEG Centre in Tübingen. After exclusion of 23 participants, 13 pregnant women with GDM and 36 pregnant women with normal glucose tolerance were examined. All women underwent the same examination setting with OGTT during which fMCG was recorded three times. Parameters of heart rate variability were measured. Compared with mothers with normal glucose regulation, mothers with GDM showed increased heart rate but no significant differences of maternal HRV. In contrast, HRV in fetuses of mothers with GDM differed from those in the metabolically healthy group regarding standard deviation normal to normal beat (SDNN) (P = 0.012), low-frequency band (P = 0.008) and high-frequency band (P = 0.031). These HRV parameters exhibit a decrease only in GDM fetuses during the second hour of the OGTT. These results show an altered response of the fetal autonomic nervous system to metabolic stress in GDM-complicated pregnancies. Hence, disturbances in maternal glucose metabolism might not only impact on the central nervous system of the fetus but may also affect the fetal autonomic nervous system. Metabolic stress reveals a different response of fetal autonomic nervous system in GDM-complicated pregnancies. © 2016 Royal College of Obstetricians and Gynaecologists.

A consensus emerged in the late 1990s among leaders in global maternal health that traditional birth attendants (TBAs) should no longer be trained in delivery skills and should instead be trained as promoters of facility-based care. Many TBAs continue to be trained in places where home deliveries are the norm and the potential impacts of this training are important to understand. The primary objective of this study was to gain a more nuanced understanding of the full impact of training TBAs to use misoprostol and a blood measurement tool (mat) for the prevention of postpartum haemorrhage (PPH) at home deliveries through the perspective of those involved in the project. This qualitative study, conducted between July 2009 and July 2010 in Bangladesh, was nested within larger operations research, testing the feasibility and acceptability of scaling up community-based provision of misoprostol and a blood measurement tool for prevention of PPH. A total of 87 in-depth interviews (IDIs) were conducted with TBAs, community health workers (CHWs), managers, and government-employed family welfare visitors (FWVs) at three time points during the study. Computer-assisted thematic data analysis was conducted using ATLAS.ti (version 5.2). Four primary themes emerged during the data analysis, which all highlight changes that occurred following the training. The first theme describes the perceived direct changes linked to the two new interventions. The following three themes describe the indirect changes that interviewees perceived: strengthened linkages between TBAs and the formal healthcare system; strengthened linkages between TBAs and the communities they serve; and improved quality of services/service utilization. The data indicate that training TBAs and CHW supervisors resulted in perceived broader and more nuanced changes than simply improvements in TBAs’ knowledge, attitudes, and practices. Acknowledgeing TBAs’ important role in the community and in home deliveries and

This qualitative study, conducted between July 2009 and July 2010 in Bangladesh, was nested within larger operations research, testing the feasibility and acceptability of scaling up community-based provision of misoprostol and a blood measurement tool for prevention of PPH. A total of 87 in-depth interviews (IDIs) were conducted with TBAs, community health workers (CHWs), managers, and government-employed family welfare visitors (FWVs) at three time points during the study. Computer-assisted thematic data analysis was conducted using ATLAS.ti (version 5.2). Four primary themes emerged during the data analysis, which all highlight changes that occurred following the training. The first theme describes the perceived direct changes linked to the two new interventions. The following three themes describe the indirect changes that interviewees perceived: strengthened linkages between TBAs and the formal healthcare system; strengthened linkages between TBAs and the communities they serve; and improved quality of services/service utilization. The data indicate that training TBAs and CHW supervisors resulted in perceived broader and more nuanced changes than simply improvements in TBAs' knowledge, attitudes, and practices. Acknowledgeing TBAs' important role in the community and in home deliveries and

A Long Look at MCG-5-23-16 with NuSTAR . I. Relativistic Reflection and Coronal Properties

MCG-5-23-16 was targeted in early 2015 with a half mega-second observing campaign using NuSTAR . Here we present the spectral analysis of these data sets along with an earlier observation and study the relativistic reflection and the primary coronal source. The data show strong reflection features in the form of both narrow and broad iron lines plus a Compton reflection hump. A cutoff energy is significantly detected in all exposures. The shape of the reflection spectrum does not change in the two years spanned by the observations, suggesting a stable geometry. A strong positive correlation is found between the cutoffmore » energy and both the hard X-ray flux and spectral index. The measurements imply that the coronal plasma is not at the runaway electron–positron pair limit, and instead contains mostly electrons. The observed variability in the coronal properties is driven by a variable optical depth. A constant heating-to-cooling ratio is measured, implying that there is a feedback mechanism in which a significant fraction of the photons cooling the corona are due to reprocessed hard X-rays.« less

Updated clinical recommendations for medical induced abortion procedure. A systematic review of French and English literature, reviewing the evidence relating to the provision of medical induced abortion was carried out on PubMed, Cochrane Library and international scientific societies recommendations. The effectiveness of medical abortion is higher than 95% when the protocols are adjusted to gestational age (EL1). Misoprostol alone is less effective than a combination of mifepristone and misoprostol (EL1). Gemeprost is less effective than misoprostol (EL2). The dose of 200mg of mifepristone should be preferred to 600mg (NP1, Rank A). Mifepristone can be taken at home (professional agreement). The optimum interval between mifepristone and misoprostol intake should be 24 to 48 hours (EL1, grade A). Before 7 weeks LMP, the dose of 400μg misoprostol should be given orally (EL1, grade A) eventually repeated after 3hours if no bleeding occurs. For optimal effectiveness between 7 and 14 LMP, the interval between mifepristone and misoprostol should not be shortened to less than 8hours (grade 1). An interval of 24 to 48hours will not affect the effectiveness of the method provided misoprostol dosage is 800μg (EL1). Vaginal, sublingual or buccal routes of administration are more effective and better tolerated than the oral route, which should be abandoned (EL1). An amount of 800μg sublingual or buccal misoprostol route has the same effectiveness than the vaginal route but more gastrointestinal side effects (EL1, grade A). Between 7 and 9 LMP, it does not seem necessary to repeat misoprostol dose whereas it should be repeated beyond 9 SA (grade B). Between 9 and 14 LMP, the dose of 400μg misoprostol given either vaginally, buccally or sublingually should be repeated every 3hours if needed (with a maximum of 5 doses) (EL2, grade B). There is no strong evidence supporting routine antibiotic prophylaxis for medical abortion (professional agreement). Rare contraindications

Background Ethinyl estradiol (EE) and progestins have the ability to alter endothelial function. The type of progestin and the ratio of EE to progestin used in oral contraceptive pills (OCPs) may determine how they affect the arterial vasculature. Study Design In this study, we investigated endothelial function across a cycle in very low dose (VLD) and low dose (LD) combination EE and desogestrel (DSG) OCP users during two phases: active (VLD=20 mcg EE/150 mcg DSG; LD=30 mcg EE/150 mcg DSG) and pill-free. Endothelial function was also measured during an EE-only hormone phase (10 mcg EE) in group VLD. Results Endothelium-dependent vasodilation was greater during the active phase compared to the pill-free phase in group LD (9.02±0.72% vs. 7.33±0.84%; p=.029). This phase difference was not observed in group VLD (5.86±0.63% vs. 6.56±0.70%; p=.108). However, endothelium-dependent vasodilation was higher during the EE-only phase, compared to the active and pill-free phases (8.92±0.47% vs. 5.86±0.63%, and 6.56±0.70%; pb.001) in group VLD. Conclusions These data suggest DSG may antagonize the vasodilatory activity of EE and that this effect is further modulated by the EE-toDSG ratio. PMID:19041440

Lubiprostone, a locally acting type-2 chloride channel activator, induces intestinal fluid secretion. To assess efficacy and safety of oral lubiprostone at multiple doses for the treatment of chronic constipation. A total of 129 patients with chronic constipation were randomized to receive lubiprostone (24, 48 or 72 mcg/day) or placebo for 3 weeks. Spontaneous bowel movement (SBM) frequency, rescue medication use, symptom assessments and adverse events (AEs) were tracked. Over the double-blinded period, mean SBM frequencies were higher for lubiprostone groups (5.1-6.1) vs. placebo (3.8) and the overall difference was statistically significant (P = 0.046). SBM frequencies at week 1 were significantly higher in patients taking lubiprostone 48 or 72 mcg/day (P < or = 0.003) and, at week 2, all three lubiprostone doses yielded significantly higher SBM rates vs. placebo (P < or = 0.020). Significantly larger proportions of patients taking lubiprostone 48 and 72 mcg/day also experienced a SBM on the first treatment day (P < or = 0.009). The most common AEs were nausea, headache and diarrhoea. Lubiprostone improved SBM rates in a dose-dependent manner. AEs were tolerable for most patients. Increased AE severity at 72 mcg/day did not provide a clear risk-to-benefit advantage compared with lubiprostone 48 mcg/day, the dose chosen for subsequent Phase 3 studies.

The virus family Papillomaviridae has been documented in a wide range of animal species and can cause benign and malignant proliferative lesions. The presence of concurrent lingual papillomas and squamous cell carcinomas (SCC) in cetaceans has also been documented in both wild and captive populations, suggesting malignant transformation of benign papilloma to SCC may occur in this species. In 2008, a 38-year-old captive male inshore bottlenose dolphin (Tursiops aduncus) was diagnosed with papillomatous lesions on the intermandibular frenulum rostral to the tongue and an infiltrative SCC of the soft palate following biopsy and histological analysis. A treatment regimen of piroxicam and doxycycline was initiated with misoprostol as a gastroprotectant. The treatment resulted in a marked reduction in tumour size and reversible hepatotoxicosis. Subsequent biopsies revealed the presence of SCC in the oral cavity; however, the disease remains stable at the time of writing. To the best of our knowledge, this case is the first report of piroxicam and doxycycline used to treat SCC in a bottlenose dolphin. The treatment was successful in reducing the clinical presentation of the disease. © 2016 Australian Veterinary Association.

Erythropoiesis-stimulating agents (ESAs) are often used in treatment of patients with chemotherapy-induced anemia. Many studies have demonstrated an improved hemoglobin (Hb) response when ESA is combined with intravenous iron supplementation and a higher effectiveness of intravenous iron over traditional oral iron formulations. A new formulation of oral sucrosomial iron featuring an increased bioavailability compared to traditional oral formulations has recently become available and could provide a valid alternative to those by intravenous (IV) route. Our study evaluated the performance of sucrosomial iron versus intravenous iron in increasing hemoglobin in anemic cancer patients receiving chemotherapy and darbepoetin alfa, as well as safety, need of transfusion, and quality of life (QoL). The present study considered a cohort of 64 patients with chemotherapy-related anemia (Hb >8 g/dL <10 g/dL) and no absolute or functional iron deficiency, scheduled to receive chemotherapy and darbepoetin. All patients received darbepoetin alfa 500 mcg once every 3 weeks and were randomly assigned to receive 8 weeks of IV ferric gluconate 125 mg weekly or oral sucrosomial iron 30 mg daily. The primary endpoint was to demonstrate the performance of oral sucrosomial iron in improving Hb response, compared to intravenous iron. The Hb response was defined as the Hb increase ≥2 g/dL from baseline or the attainment Hb ≥ 12 g/dL. There was no difference in the Hb response rate between the two treatment arms. Seventy one percent of patients treated with IV iron achieved an erythropoietic response, compared to 70% of patients treated with oral iron. By conventional criteria, this difference is considered to be not statistically significant. There were also no differences in the proportion of patients requiring red blood cell transfusions and changes in QoL. Sucrosomial oral iron was better tolerated.

Dexmedetomidine is increasingly used by various routes for pediatric sedation. However, there are few randomized controlled trials comparing the efficacy of dexmedetomidine to other commonly used sedatives. To compare the efficacy of sedation with intranasal dexmedetomidine to oral chloral hydrate for auditory brainstem response (ABR) testing. In this double-blind, double-dummy study, children undergoing ABR testing were randomized to receive intranasal dexmedetomidine 3 mcg · kg(-1) plus oral placebo (Group IN DEX) or oral chloral hydrate 50 mg · kg(-1) plus intranasal saline placebo (Group CH). We recorded demographic data, times from sedative administration to start and completion of testing, quality of sedation, occurrence of predefined adverse events, discharge times, and return to baseline activity on the day of testing. Testing completion rates with a single dose of medication were higher in the IN DEX group (89% vs 66% for CH, odds ratio with 95% confidence intervals 4.04 [1.3-12.6], P = 0.018). The median [95% CI)] time to successful testing start was shorter (25 [20-29] min vs 30 [20-49] min for IN DEX and CH, respectively, log rank test P = 0.02) and the proportion of children whose parents reported a return to baseline activity on the day of testing was greater for the IN DEX than the CH group (89% vs 64%, OR [95% CI] 4.71 [1.34-16.6], P = 0.02). There were no major adverse events in either group and no significant differences in the incidence of minor events. Intranasal dexmedetomidine is an effective alternative to oral chloral hydrate sedation for ABR testing, with the advantages of a higher incidence of testing completion with a single dose, shorter time to desired sedation level, and with significantly more patients reported to return to baseline activity on the same day. © 2016 John Wiley & Sons Ltd.

Background Anorexia nervosa (AN) is prevalent in adolescents and is associated with decreased bone mineral accrual at a time critical for optimizing bone mass. Low bone mineral density (BMD) in AN is a consequence of nutritional and hormonal alterations, including hypogonadism and low estradiol levels. Effective therapeutic strategies to improve BMD in adolescents with AN have not been identified. Specifically, high estrogen doses given as an oral contraceptive do not improve BMD. The impact of physiological estrogen doses that mimic puberty on BMD has not been examined. Subjects and Methods We enrolled 110 girls with AN and 40 normal-weight controls (C) 12–18y of similar maturity. Subjects were studied for 18 months. Mature AN [bone age (BA) ≥15 y; n=96] were randomized to transdermal 100mcg 17β-estradiol (with cyclic progesterone) or placebo for 18m. Immature AN (BA <15y; n=14) were randomized to incremental low dose oral ethinyl-estradiol (3.75mcg daily from 0–6m, 7.5mcg from 6–12m, 11.25mcg from 12–18m) to mimic pubertal estrogen increases, or placebo for the 18m duration. Results All BMD measures assessed by dual energy x-ray absorptiometry (DXA) were lower in AN than C. At baseline, AN randomized to estrogen (AN E+) did not differ from those randomized to placebo (AN E−) for age, maturity, height, BMI, amenorrhea duration and BMD parameters. Spine and hip BMD Z-scores increased over time in the AN E+ compared with AN E− group, even after controlling for baseline age and weight. Conclusion Physiological estradiol replacement increases spine and hip BMD in girls with AN. PMID:21698665

A SUZAKU OBSERVATION OF MCG -2-58-22: CONSTRAINING THE GEOMETRY OF THE CIRCUMNUCLEAR MATERIAL

We have analyzed a long-look Suzaku observation of the active galactic nucleus MCG -2-58-22, a type 1.5 Seyfert with very little X-ray absorption in the line of sight and prominent features arising from reflection off circumnuclear material: the Fe line and Compton reflection hump. We place tight constraints on the power-law photon index ({Gamma} = 1.80 {+-} 0.02), the Compton reflection strength (R = 0.69 {+-} 0.05), and the Fe K emission line energy centroid and width (E = 6.40 {+-} 0.02 keV, v{sub FWHM} < 7100 km s{sup -1}). We find no significant evidence either for emission from stronglymore » ionized Fe, or for a strong, relativistically broadened Fe line, indicating that perhaps there is no radiatively efficient accretion disk very close in to the central black hole. In addition, we test a new self-consistent physical model from Murphy and Yaqoob, the 'MYTORUS' model, consisting of a donut-shaped torus of material surrounding the central illuminating source and producing both the Compton hump and the Fe K line emission. From the application of this model we find that the observed spectrum is consistent with a Compton-thick torus of material (column density N{sub H} = 3.6{sup +1.3}{sub -0.8} x 10{sup 24} cm{sup -2}) lying outside of the line of sight to the nucleus, leaving it bare of X-ray absorption in excess of the Galactic column. We calculate that this material is sufficient to produce all of the Fe line flux without the need for any flux contribution from additional Compton-thin circumnuclear material.« less

Advance provision of misoprostol to women during antenatal care aims to achieve broader access to uterotonics for the prevention of postpartum hemorrhage. Studies of this community-based approach usually involve antenatal education as well as timely postpartum follow-up visits to confirm maternal and neonatal outcomes. The MamaMiso study in Mbale, Uganda sought to assess the feasibility of conducting follow-up visits in the postpartum period following advance provision of misoprostol for postpartum hemorrhage prevention. MamaMiso recruited women during antenatal care visits. Participants were asked to contact the research team within 48 h of giving birth so that postpartum follow-up visits could be carried out at their homes. Women's baseline and delivery characteristics were collected and analyzed with respect to follow-up time ('on time' ≤ 7 days, 'late' > 7 days, and 'lost to follow up'). Every woman who was followed up late due to a failure to report the delivery was asked for the underlying reasons for the delay. When attempts at following up participants were unsuccessful, a file note was generated explaining the details of the failure. We abstracted data and identified themes from these notes. Of 748 recruited women, 700 (94%) were successfully followed up during the study period, 465 (62%) within the first week postpartum. The median time to follow up was 4 days and was similar for women who delivered at home or in facilities and for women who had attended or unattended births. Women recruited at the urban hospital site (as opposed to rural health clinics) were more likely to be lost to follow up or followed up late. Of the women followed up late, 202 provided a reason. File notes explaining failed attempts at follow up were generated for 164 participants. Several themes emerged from qualitative analysis of these notes including phone difficulties, inaccurate baseline information, misperceptions, postpartum travel, and the condition of the mother

Background: Postoperative transient hypocalcemia is sequelae of total thyroidectomy (TT), which is observed in up to 50% of patients. Routine oral calcium and Vitamin D supplementation have been proposed to prevent symptomatic hypocalcemia preventing morbidity and facilitating early discharge. Patients and Methods: A total of 208 patients with nontoxic benign thyroid disorders, undergoing TT, were serially randomized into four groups: Group A (no supplements were given), Group B (oral calcium – 2 g/day given), Group C (calcium and calcitriol – 1 mcg/day are given), and Group D (calcium, calcitriol, and cholecalciferol – 60,000 IU/day are given). Patients were monitored for clinical and biochemical hypocalcemia (serum calcium, [Sr. Ca] <8 mg/dl), along with serum intact parathormone (Sr. PTH) and magnesium 6 h after surgery and Sr. Ca every 24 h. Intravenous (IV) calcium infusion was started, if any of the above four groups exhibit frank hypocalcemia. Patients are followed up with Sr. Ca and Sr. PTH at 3 and 6 months. Results: All groups were age and sex matched. Hypocalcemia was observed in 72/208 (34.61%) cases. Incidence of hypocalcemia was higher in Group A (57.69%) and Group B (50%) compared to Group C (15.38%) and Group D (15.38%). Hypocalcemia necessitating IV calcium occurred in 31/208 (14.90%) patients. IV calcium requirement exceeded in Group A (26.92%) and Group B (23.07%) compared to Group C (5.76%) and Group D (3.84%). There was no statistical difference in basal levels of serum Vitamin D, calcium, magnesium, intact PTH, and 6 h after surgery. Permanent hypoparathyroidism developed in five patients on follow-up. Conclusion: Routine postoperative supplementation of oral calcium and Vitamin D will help in the prevention of postthyroidectomy transient hypocalcemia significantly. Preoperative Vitamin D levels do not predict postoperative hypocalcemia. PMID:28670529

Hysteroscopy is an operation in which the gynaecologist examines the uterine cavity using a small telescopic instrument (hysteroscope) inserted via the vagina and the cervix. Almost 50% of hysteroscopic complications are related to difficulty with cervical entry. Potential complications include cervical tears, creation of a false passage, perforation, bleeding, or simply difficulty in entering the internal os (between the cervix and the uterus) with the hysteroscope. These complications may possibly be reduced with adequate preparation of the cervix (cervical ripening) prior to hysteroscopy. Cervical ripening agents include oral or vaginal prostaglandin, which can be synthetic (e.g misoprostol) or natural (e.g. dinoprostone) and vaginal osmotic dilators, which can be naturally occurring (e.g. laminaria) or synthetic. To determine whether preoperative cervical preparation facilitates cervical dilatation and reduces the complications of operative hysteroscopy in women undergoing the procedure for any condition. In August 2014 we searched sources including the Menstrual Disorders and Subfertility Group (MDSG) Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO, CINAHL, ClinicalTrials.gov and reference lists of relevant articles. We searched for published and unpublished studies in any language. Two review authors independently selected randomised controlled trials (RCTs) of cervical ripening agents used before operative hysteroscopy in pre- and postmenopausal women. Cervical ripening agents could be compared to each other, placebo or no treatment. Data extraction and quality assessment were conducted independently by two review authors. The primary review outcomes were effectiveness of cervical dilatation (defined as the proportion of women requiring mechanical cervical dilatation) and intraoperative complications. Secondary outcomes were mean time required to dilate the cervix, preoperative pain, cervical width

This study compared the bleeding pattern, cycle control and safety of an oral contraceptive (OC) comprising estradiol valerate/dienogest (E2V/DNG; administered using a dynamic dosing regimen) with a monophasic OC containing ethinyl estradiol 20 mcg/levonorgestrel 100 mcg (EE/LNG). E2V releases estradiol (E2), which is identical to endogenously produced 17beta-estradiol. This was a randomized, multicenter, double-blind, double-dummy trial lasting seven cycles in healthy women aged 18-50 years. Overall, 798 women were randomized and received allocated treatment (399 per group). There were significantly fewer bleeding/spotting days reported by women who received E2V/DNG than those who received EE/LNG [17.3+/-10.4 vs. 21.5+/-8.6, respectively, p<.0001, Reference Period 1 (Days 1-90); and 13.4+/-9.vs. 15.9+/-7.1, respectively, p<.0001, Reference Period 2 (Days 91-180)]. Through Cycles 1-7, the occurrence of scheduled withdrawal bleeding per cycle was 77.7-83.2% with E2V/DNG and 89.5-93.8% with EE/LNG (p<.0001 per cycle). The duration and intensity of scheduled withdrawal bleeding were reduced with E2V/DNG vs. EE/LNG. The incidence of intracyclic bleeding was similar with E2V/DNG (10.5%-18.6%) and EE/LNG (9.9%-17.1%) (p>.05 per cycle). No unintended pregnancies occurred with E2V/DNG, but there was one unintended pregnancy with EE/LNG. Adverse drug reactions occurred in 10.0% and 8.5% of women taking E2V/DNG and EE/LNG, respectively. Overall, 79.4% of women were satisfied with E2V/DNG and 79.9% with EE/LNG. A novel OC composed of E2V/DNG is associated with an acceptable bleeding profile that is comparable to that of an EE-containing OC.

In 2009, the Nepal Ministry of Health and Population launched a national program for prevention of postpartum hemorrhage (PPH) during home births that features advance distribution of misoprostol to pregnant women. In the years since, the government has scaled-up the program throughout much of the country. This paper presents findings from the first large-scale assessment of the effectiveness of the advance distribution program. Data collection was carried out in nine districts and all three ecological zones. To assess knowledge, receipt and use of misoprostol, household interviews were conducted with 2070 women who had given birth within the past 12 months. To assess supply and provision of misoprostol, interviews were conducted with 270 Female Community Health Volunteers (FCHVs) and staff at 99 health facilities. Among recently delivered women, only 15% received information about misoprostol and 13% received misoprostol tablets in advance of delivery. Yet 87% who received advance misoprostol and delivered at home used it for PPH prevention. Among FCHVs, 96% were providing advance misoprostol for PPH prevention; however 81% had experienced at least one misoprostol stock out within the past year. About one-half of FCHVs were providing incomplete information about the use of misoprostol; in addition, many did not discuss side effects, how to recognize PPH or where to go if PPH occurs. Among health facilities, just one-half had sufficient misoprostol stock, while 95% had sufficient oxytocin stock, at the time of this assessment. In Nepal, women who receive advance misoprostol are both willing and able to use the medication for PPH prevention during home births. However the supply and personnel challenges identified raise questions about scalability and impact of the program over the long-term. Further assessment is needed.

To assess the feasibility of following up women who purchase mifepristone+misoprostol or misoprostol-only from pharmacies in order to measure the safety and effectiveness of self-administration of menstrual regulation. A prospective cohort study followed women purchasing mifepristone+misoprostol or misoprostol-only from pharmacies in Bangladesh. Participants were recruited by pharmacy workers either in person or indirectly via the purchaser of the drugs. End users were contacted by phone 2 weeks after recruitment, screened and interviewed. Study recruitment rates by pharmacy workers were low (30%, 109 of 642 women informed about the study), but 2-week follow-up rates were high (87%). Of the 109 end users interviewed, 87 purchased mifepristone+misoprostol and 20 misoprostol-only, while 2 women did not know what drugs they had purchased. Mean self-reported number of weeks of pregnancy was 5.7 weeks. Information provision by pharmacy workers was inadequate (40.4% received none, 8.7% received written information or pictures). A total of 80.5% of mifepristone+misoprostol users were sold the correct regimen versus 9 out of 20 misoprostol-only users. A total of 68.8% did not report experiencing any complications (70.0% misoprostol-only; 69.0% mifepristone+misoprostol users, p=1.0). A total of 94.3% of mifepristone+misoprostol users and 75% of misoprostol-only users reported that they were not pregnant at day 15 (p=.020). However, 7.3% of all users sought additional treatment. Challenges in assessing outcomes of self-managed menstrual regulation medications purchased from pharmacies must be overcome through further development of this methodology. Interventions are urgently needed to ensure that women have access to correct dosages, accurate information and necessary referrals. This paper assesses the outcomes of women who self-manage menstrual regulation medications purchased from pharmacies. The methodology requires further development, but our study provides preliminary

[Oral contraception and the vascular risk].

PubMed

Garnier, L F; Gruel, Y

Vascular risk, mainly thromboembolitic risk, attributed to oral contraceptives (OCs) since 1962, has been primarily linked to ethinyl estradiol (EE). OCs which combine estrogen and have been associated with cerebral vascular accidents. A 1977 study showed a 40% increase of mortality due to cardiovascular complications in women taking OCs. There were of both an arterial and a venous character. The risk of myocardial infarction was 3 times more frequent among OC users. Deep venous thrombosis and pulmonary embolism were more numerous. Some other risk factors include smoking, hypertension, diabetes, and age 35. The risk of heart attack vanishes a few years after stopping OC use. The reduction of EE (and similarly progesterone) dosage from 100-50 mcg also lower the risk of hypertension, cerebral vascular accidents, and venous thrombosis. Prolonged use of OCs causes disorders of hemostasis affecting the walls of blood vessels, modifying the viscosity of blood flow (increase of hematocrits, reduction of venous tonus), modifying plasmatic coagulation (increase of platelets, increase of factors VII and X and plasma fibrinogen, and decrease of antithrombin III activity), and increased fibrinolysis. These anomalies are exclusively associated with high doses of estrogens. 5% of women using OCs develop moderate hypertension of 5-10 mm Hg of systolic pressure 5 years later, but after cessation it is reversed. OCs stimulate the renin-angiotensin-aldosterone system causing accelerated production of angiotensin II with the resultant forceful vasotension. 3 months after quitting OC use, high blood pressure returns to normal. EE can provoke diabetes; it increases very low density lipoprotein (VLDL) and high density lipoprotein (HDL) production, but total cholesterol is hardly affected. The androgenic property of progestogens reduces HDL. Combined OCs are contraindicated for women with hypertension, hyperlipidemia, diabetes, and a family history of vascular accidents.

The objective was to investigate changes in luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2) and progesterone (P) during the hormone-free interval (HFI) of 6 combined oral contraceptives (COCs). Blood samples were obtained from 62 women. When COCs were grouped by ethinyl estradiol (EE) dose, there was a significant positive mean slope for LH and FSH during the HFI for the 30- and 35 mcg-EE doses, whereas 20 showed a gradual nonsignificant slope. All E2 slopes were significant. P remained suppressed with all doses. A more rapid rebound of gonadotropin levels is found with higher doses of EE during the HFI. This study showed a more rapid rebound of pituitary hormone levels among women using higher-EE-dosage formulations, which was demonstrated by the statistically significant slope for mean LH and FSH from day 1 to day 7 of the HFI. The degree of suppression did not vary across progestin generations. It remains to be established whether women who experience side effects during their HFI may benefit from using a COC with a lower EE dose to minimize changes in endogenous pituitary hormone levels.

To assess the efficacy of medical abortion and patient satisfaction in the clinic setting, in addition to determining healthcare providers' views. From 2006 to 2008, 2400 women were enrolled at 10 Vietnam Family Planning Association (VINAFPA) clinics in an operations research project. Participants took 200mg of oral mifepristone in the clinic and 400 μg of oral misoprostol 2 days later at home or in the clinic. Abortion status was assessed at follow-up. Furthermore, in 2006, 900 clinicians at 45 health facilities answered a knowledge, attitudes, and practices survey to capture providers' views. In total, 93.8% of participants had successful medical abortions. The majority (84.5%) administered misoprostol at home. Adverse effects included bleeding, pain/cramps, and nausea. Most women (92.6%) were satisfied/very satisfied with the method. Most providers who took the survey (85.6%) recommended that medical abortion be introduced at VINAFPA clinics. The operations research data demonstrate the safety, efficacy, and acceptability of medical abortion at VINAFPA clinics. The majority of surveyed providers endorsed adding medical abortion at their own facilities. Developing national guidelines for providing medical abortion at the clinic level is an important step in expanding access to services in Vietnam.

The increase in demand and consumption of single clove garlic or 'Solo garlic' (Allium sativum) has resulted in an increase in research on its therapeutic properties. The present study aims to evaluate the antioxidant activities, oxidant-scavenging efficiency and preventive effects of SCG (single clove garlic) and MCG (multi clove garlic) on CCl 4 -induced acute hepatotoxicity in male rabbits. For this purpose, rabbits were orally administered with 3 ml of CCl 4 /kg of body weight, followed by 0.8 g of MCG or SCG/kg twice a week for three successive weeks. Oxidative hepatotoxicity was then assessed. SCG extracts exhibited higher antioxidant capacity than the MCG extract. Scavenging ability of SCG showed significant (p < 0.05) elevation against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide radicals in comparison to MCG. In addition, total phenolic content of SCG was significantly elevated (p < 0.001), thereby suggesting that the composition of garlic storage constituents varies with the number of cloves present. CCl 4 -induced hepatotoxicity demonstrated histological changes including severe damage in the structure of liver tissues which correlated well to oxidative stress levels. Simultaneously, administration of SCG resulted in a significant reduction of serum alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin (TB) levels in addition to improvement in some histological parameters. Low levels of lipid peroxidation (malondialdehyde, MDA) (p < 0.001), along with a huge reduction in peroxidase (POx) (p < 0.001) revealed protection against oxidative toxicity in the liver homogenate. Higher levels of catalase (CAT) (p < 0.001) and superoxide dismutase (SOD) (p < 0.05) when compared to the MCG test (TM) group indicates that removal of H 2 O 2 is based on CAT activity in SCG test (TS) group rather than the POx activity demonstrated in the former group. The present study indicates that SCG

Objective The aim of this study was to evaluate adverse effects of oral desmopressin lyophilisate (MELT) in enuretic children. Material and methods We enrolled 260 children with nocturnal enuresis (NE) referred to the Pediatric Service, ‘Campus Bio-Medico’ University of Rome, from April 2014 to April 2017 in the study, of these 23 were excluded. The study was characterized by 2 phases. During Phase 1 a careful patient’s medical history was obtained and physical examination was performed. After 3 months of treatment with MELT (Minirin/DDAVP®) at the dose of 120 mcg a day, a micturition diary was kept, adherence to therapy and any possible adverse effects were checked during the Phase 2. The study was carried out in compliance with the Helsinki Declaration. Results Among 237 patients included in the study 11 male and 6 female (n=17; 7.2%) patients with a mean age 10.06±2.49 years, reported 22 adverse effects, with an absolute risk of 7.17%. In particular, 5 neurological symptoms, 3 gastrointestinal effects, 4 sleep disturbances, 8 psycho-behavioral disorders, 2 symptoms of fatigue were reported. Conclusion In our study MELT with its higher bioavailability guaranteed lower frequency of adverse effects which resolved spontaneously and rapidly. The MELT formulation actually represents the first line and safe treatment for the NE. PMID:29484228

Transdermal buprenorphine, which is used in chronic pain management, has rarely been studied for use in acute pain management. The aim of this study was to compare the safety and efficacy of transdermal buprenorphine patch to oral tramadol for post-operative analgesia, following proximal femur surgeries. Fifty adult patients undergoing surgery for hip fracture under spinal anaesthesia were included in this study. One group (Group TDB) received transdermal buprenorphine 10 mcg/h patch applied a day before the surgery and other group received oral tramadol 50 mg three times a day for analgesia (Group OT). They were allowed to take diclofenac and paracetamol tablets for rescue analgesia. Pain scores at rest, on movement, rescue analgesic requirement and side effects were compared between the groups over 7 days. Chi-square and independent sample t -test were used for categorical and continuous variables, respectively. Resting pain scores and pain on movement were significantly lower in TDB Group on all 7 days starting from 24 h post-operatively. Rescue analgesic requirement was significantly lower in TDB Group compared to OT Group. All the patients needed rescue analgesic in OT Group whereas 68% of the patients needed the same in TDB Group. Incidence of vomiting was less and satisfaction scores were much higher in TDB Group as compared to OT Group (79% vs. 66%, P < 0.001). Transdermal buprenorphine can be safely used for post-operative analgesia and is more efficacious in reducing post-operative pain after 24 hours, with fewer side effects when compared to oral tramadol.

Elective colorectal surgery without bowel preparation: a historical control and case-matched study.

Although full bowel preparation, including mechanical washout and non-absorbable antibiotherapy, has been considered for decades as a prerequisite to any elective colorectal surgery, recent literature has suggested that this habit was perhaps unjustified. The aim of this study was to assess the safety of ileocolic, colocolic and colorectal anastomosis in the absence of pre-operative mechanical bowel preparation. During a 1-year period, 59 consecutive patients underwent elective colorectal surgery with ileocolic, colocolic or colorectal anastomosis without any pre-operative preparation. This "non-prepared group" (NPG) was compared to a "control group" (CG) composed of the previous 127 consecutive cases of classically managed patients. To improve the statistical power we also compared the NPG to a "match-controlled group" (MCG) of 59 patients within the CG. Primary end-points were anastomotic leakage and abdominal infections. Secondary end-points were oral diet resume time and hospital stay. There were no differences between the 3 groups for age, gender, BMI, immunodepression status, anastomosis site and suture technique. There were no differences between NPG and CG or MCG for anastomotic leakage (3.5%, 4.7% and 6.8% respectively, NPG/CG p = 0.68 and NPG/MCG p = 0.4) or for infectious abdominal complications. Mean diet resume time was 1.4 (1-5) days in the NPG versus 3.4 (1-19) days in the CG and 3.1 (1-6) days in the MCG (p < 0.00001). Median length of postoperative hospital stay was 5 (2-81) days in the NPG versus 8 (4-100) and 8 (4-100) in the CG and the MCG respectively. In accordance with the recent literature, the present experience does not show any benefit of mechanical bowel preparation in elective colorectal resection. This suggests that bowel preparation could be omitted before this type of surgery.

Induced abortion: an overview for internists.

PubMed

Grimes, David A; Creinin, Mitchell D

2004-04-20

Internists care for many women who have had abortions and many who will seek abortions in the future. Each year, about 2% of all women of reproductive age have an abortion. Women having abortions tend to be young, white, unmarried, and early in pregnancy. Most abortions are done by suction curettage under local anesthesia in a freestanding clinic. However, medical abortion is growing in popularity as a nonsurgical alternative. The regimen approved by the U.S. Food and Drug Administration specifies mifepristone, 600 mg orally, followed 2 days later by misoprostol, 400 microg orally (within 49 days from last menses). Recent studies have recommended alternative approaches, such as mifepristone, 200 mg orally, followed in 1 to 3 days by misoprostol, 800 microg vaginally (up to 63 days). Medical abortion can be provided by a broader variety of physicians than can surgical abortion. The overall case-fatality rate for abortion is less than 1 death per 100,000 procedures. Infection, hemorrhage, acute hematometra, and retained tissue are among the more common complications. Referral back to the original abortion provider for management is advisable. Overall, induced abortion does not lead to late sequelae, either medical or psychiatric. Of importance, no link exists between induced abortion and later breast cancer. For physicians who are asked to help with a referral, the National Abortion Federation and Planned Parenthood Federation of America have helpful Web sites and networks of high-quality clinics. The cost of abortion (currently about 372 dollars at 10 weeks) has decreased in recent decades. Provision of ongoing contraception and encouragement of emergency contraception can reduce unintended pregnancies and the need for abortion.

The use of proton pump inhibitors or misoprostol is known to prevent the gastrointestinal complications of nonsteroidal anti-inflammatory drugs (NSAIDs). Rebamipide is known to increase the mucosal generation of prostaglandins and to eliminate free oxygen radicals, thus enhancing the protective function of the gastric mucosa. However, it is unknown whether rebamipide plays a role in preventing NSAID-induced gastropathy. The aim of this study was to determine the effectiveness of rebamipide compared to misoprostol in preventing NSAID-induced gastrointestinal complications in patients requiring continuous NSAID treatment. We studied 479 patients who required continuous NSAID treatment. The patients were randomly assigned to groups that received 100 mg of rebamipide three times per day or 200 μg of misoprostol three times per day for 12 weeks. The primary endpoint of the analysis was the occurrence rate of gastric ulcers, as determined by endoscopy after 12 weeks of therapy. Of the 479 patients in the study, 242 received rebamipide, and 237 received misoprostol. Ultimately, 44 patients (18.6%) withdrew from the misoprostol group and 25 patients (10.3%) withdrew from the rebamipide group. There was a significant difference in withdrawal rate between the two groups (p=0.0103). The per protocol analysis set was not valid because of the dropout rate of the misoprostol group; thus, the intention to treat (ITT) analysis set is the main set for the efficacy analysis in this study. After 12 weeks, the occurrence rate of gastric ulcers was similar in the rebamipide and misoprostol groups (20.3% vs 21.9%, p=0.6497) according to ITT analysis. In addition, the therapeutic failure rate was similar in the rebamipide and misoprostol groups (13.6% vs 13.1%, p=0.8580). The total severity score of the gastrointestinal symptoms was significantly lower in the rebamipide group than in the misoprostol group (p=0.0002). The amount of antacid used was significantly lower in the rebamipide

To compare the level of pain reported by women by dose of mifepristone, 200 or 600mg, and describe the main factors related to the pain level in the 5 days after a medical abortion. Observational study in 11 medical centers in France between October 2013 and September 2014. The protocols were 200 or 600mg orally mifepristone on day 1 of the medical abortion and 400, 600 or 800μg orally misoprostol on day 3. Women returned a questionnaire that they completed during 5 days following the abortion; pain was recorded on a visual analog scale (0-10) daily. 453 women were included; the mean age was 29 years (range 18-49 years). Pain was greater with 200 than 600mg mifepristone: 33% of women reported a pain level of ≥8 on day 3 with 200mg as compared with 16% with 600mg. This difference remained after controlling for age, gestational age, gravidity, usual painful menstruation and misoprostol dose. Percentages of symptoms as vomiting or diarrhea were also lower with 600mg mifépristone than 200mg. The mean pain severity experienced by women undergoing medical abortion is high; it is higher with a regimen of 200mg mifepristone. The findings emphasize the need to improve analgesic strategies and invite to opt for a protocol of 600mg instead of 200mg mifepristone. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Previous pregnancies may influence the success of medical termination of pregnancy. To determine the effect of parity and gravidity on the successful termination of pregnancy using mifepristone and misoprostol. The medical files of all patients attending a department of obstetrics and gynecology during the years 2006 and 2007 for the purpose of medical termination of pregnancy at < or = 49 days of gestation were analyze retrospectively. The medical history, previous pregnancies and deliveries were recorded. Mifepristone was administered orally followed by 400 mg of misoprostol 48 hours later. A second dose of misoprostol was offered 2 weeks later if uterine content thickness was more than 15 mm. Then, after 24 hours, if uterine content thickness was more than 15 mm the uterus was evacuated by dilation and curettage. Of 403 women, 349 (86.6%) aborted following the basic regime; 207 (51.4%) (group A) were primiparous while 196 (48.6%) (group B) had at least one prior pregnancy. Uterine curettage was performed in 17 patients (8.2%) in group A and in 37 (18.9%) in group B (P = 0.002). When patients with a history of a previous abortion were excluded from group B, 32 of 143 (22.4%) required curettage (P < 0.001). When patients without a history of previous cesarean section were excluded, 10 of 52 (19.2%) underwent curettage (P = 0.038). Previous pregnancies negatively affect the success of medical termination of pregnancy, especially in women with a previous term pregnancy. This information is important when counseling women about the method of pregnancy termination.

The purpose of this systematic review was to evaluate the efficacy of pretreatment with letrozole prior to either a first- or second-trimester medical termination of pregnancy. We searched letrozole, femara, aromatase inhibitors, abortifacient agents, termination of pregnancy and labor induction in MEDLINE, EMBASE, Cochrane Database, Google Scholar and PubMed from inception of each database until September 2015 with no language limitation. A systematic review of all randomized controlled trials (RCTs) was performed where women received either letrozole and misoprostol or placebo and misoprostol for termination of pregnancy. The primary outcome was complete abortion rate, defined as complete evacuation of the products of conception from the uterus. Relative risk with 95% confidence intervals was used to report data. Our systematic review identified 7 studies; 4 RCTs were included in the review. Two RCTs evaluated terminations of pregnancy up to 9 weeks' gestation, while 2 evaluated terminations over 9 weeks' gestation. For each gestational age group, one trial supported an increase in complete abortion rate, while the other showed no difference, with letrozole and misoprostol compared with placebo and misoprostol. Time-to-abortion interval for terminations up to 9 weeks' gestation was not improved with the addition of letrozole to misoprostol. For terminations over 9 weeks' gestation, one trial supported and one trial refuted a decrease in time-to-abortion interval with letrozole and misoprostol. Similarly, for each gestational age group, one study supported a decrease and one study showed no difference in rate of dilation and curettage (D&C) with letrozole and misoprosol. Medication side effects were similar between both treatment groups. There was significant heterogeneity between the trials, and therefore, the results were not meta-analyzed. Some studies and trials report better outcomes (i.e., complete abortion rates, time-to-abortion and D&C rates) in women

Oral human papillomavirus (HPV) infection is the cause of 40% to 80% of oropharyngeal cancers; yet, no published study has examined the role of oral health in oral HPV infection, either independently or in conjunction with other risk factors. This study examined the relation between oral health and oral HPV infection and the interactive effects of oral health, smoking, and oral sex on oral HPV infection. Our analyses comprised 3,439 participants ages 30 to 69 years for whom data on oral HPV and oral health were available from the nationally representative 2009-2010 National Health and Nutrition Examination Survey. Results showed that higher unadjusted prevalence of oral HPV infection was associated with four measures of oral health, including self-rated oral health as poor-to-fair [prevalence ratio (PR) = 1.56; 95% confidence interval (CI), 1.25-1.95], indicated the possibility of gum disease (PR = 1.51; 95% CI, 1.13-2.01), reported use of mouthwash to treat dental problems in the past week (PR = 1.28; 95% CI, 1.07-1.52), and higher number of teeth lost (Ptrend = 0.035). In multivariable logistic regression models, oral HPV infection had a statistically significant association with self-rated overall oral health (OR = 1.55; 95% CI, 1.15-2.09), independent of smoking and oral sex. In conclusion, poor oral health was an independent risk factor of oral HPV infection, irrespective of smoking and oral sex practices. Public health interventions may aim to promote oral hygiene and oral health as an additional measure to prevent HPV-related oral cancers.

To compare hormone levels and symptoms during transition from standard to extended oral contraceptive (OC) regimens. A prospective analysis of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and inhibin-B levels with symptoms during 21/7-day vs. 168/7-day extended OCs containing 3 mg of drosperinone and 30 mcg of ethinyl estradiol. Blood samples were obtained from 10 subjects in each of 4 weeks in the 21/7 regimen, in the first 6 weeks of the extended regimen, and again the week before, the week of and the week after the 7-day hormone-free interval (HFI) at the end of the extended regimen. All 4 hormones followed a cyclic pattern with decreasing levels during the 3 active pill weeks of the 21/7 cycle, followed by an increase during the 7-day HFI, which continued into the extended regimen. Levels then decreased during the extended regimen and remained low at week 24. During the 7-day HFI after the extended regimen FSH and LH again increased above baseline (p > 0.07). Hormone withdrawal symptoms increased at the end of 21 active pills with increasing severity during the 7-day HFI. Absence of pituitary and ovarian suppression associated with HFI leads to fluctuations in hormones and associated hormone withdrawal symptoms.

Many oral lesions may need to be diagnosed by removing a sample of tissue from the oral cavity. Biopsy is widely used in the medical field, but the practice is not quite widespread in dental practice. As oral pathologists, we have found many artifacts in the tissue specimen because of poor biopsy technique or handling, which has led to diagnostic pitfalls and misery to both the patient and the clinician. This article aims at alerting the clinicians about the clinical faults arising preoperatively, intraoperatively and postoperatively while dealing with oral biopsy that may affect the histological assessment of the tissue and, therefore, the diagnosis. It also reviews the different techniques, precautions and special considerations necessary for specific lesions.

An estimated 282 women die for every 100,000 live births in Myanmar, most due to preventable causes. Auxiliary Midwives (AMWs) in Myanmar are responsible for providing a package of care during pregnancy and childbirth to women in rural hard to reach areas where skilled birth attendants (Midwives) are not accessible. This study aims to examine the role of AMWs in Myanmar and to assess the current practices of three proposed essential maternal interventions (oral supplement distribution to pregnant women; administration of misoprostol to prevent postpartum haemorrhage; management of puerperal sepsis with oral antibiotics) in order to facilitate a formal integration of these tasks to AMWs in Myanmar. A mixed methods study was conducted in Magwe Region, Myanmar involving a survey of 262 AMWs, complemented by 15 focus group discussions with midwives (MWs), AMWs, mothers and community members, and 10 key informant interviews with health care providers at different levels within the health care system. According to current government policy, AMWs are responsible for identifying pregnant women, screening for danger signs and facilitating early referral, provision of counselling on nutrition and birth preparedness for women in hard-to-reach areas. AMWs also assist at normal deliveries and help MWs provide immunization services. In practice, they also provide oral supplements to pregnant women (84%), provide antibiotics to mothers during the puerperium (43%), and provide misoprostol to prevent postpartum haemorrhage (41%). The current practices of AMWs demonstrate the potential for task shifting on selected essential maternal interventions. However, to integrate these interventions into formal practice they must be complemented with appropriate training, clear guidelines on drug use, systematic recording and reporting, supportive monitoring and supervision and a clear political commitment towards task shifting. With the current national government's commitment towards one

Oral diseases are known to be closely associated with oral biofilm metabolism, while cancer tissue is reported to possess specific metabolism such as the 'Warburg effect'. Metabolomics might be a useful method for clarifying the whole metabolic systems that operate in oral biofilm and oral cancer, however, technical limitations have hampered such research. Fortunately, metabolomics techniques have developed rapidly in the past decade, which has helped to solve these difficulties. In vivo metabolomic analyses of the oral biofilm have produced various findings. Some of these findings agreed with the in vitro results obtained in conventional metabolic studies using representative oral bacteria, while others differed markedly from them. Metabolomic analyses of oral cancer tissue not only revealed differences between metabolomic profiles of cancer and normal tissue, but have also suggested a specific metabolic system operates in oral cancer tissue. Saliva contains a variety of metabolites, some of which might be associated with oral or systemic disease; therefore, metabolomics analysis of saliva could be useful for identifying disease-specific biomarkers. Metabolomic analyses of the oral biofilm, oral cancer, and saliva could contribute to the development of accurate diagnostic, techniques, safe and effective treatments, and preventive strategies for oral and systemic diseases.

Myo-inositol and D-chiro-inositol are capable of improving the ovarian function and metabolism of polycystic ovary syndrome (PCOS) patients. The aim of this work is to compare the effects of myo-inositol and D-chiro-inositol in PCOS. We enrolled 50 patients, with homogeneous bio-physical features, affected by PCOS and menstrual irregularities, and we randomly divided them into two groups: 25 were treated with 4 g of myo-inositol/die plus 400 mcg of folic acid/die orally for six months, 25 with 1 g of D-chiro-inositol/die plus 400 mcg of folic acid/die orally for six months. We analyzed in both groups pre-treatment and post-treatment BMI, systolic and diastolic blood pressure, Ferriman-Gallwey score, Cremoncini score, serum LH, LH/FSH ratio, total and free testosterone, dehydroepiandrosterone sulfate (DHEA-S), Δ-4-androstenedione, SHBG, prolactin, glucose/immunoreactive insulin (IRI) ratio, homeostatic model assessment (HOMA) index, and the resumption of regular menstrual cycles. Both the isoforms of inositol were effective in improving ovarian function and metabolism in patients with PCOS, although myo-inositol showed the most marked effect on the metabolic profile, whereas D-chiro-inositol reduced hyperandrogenism better.

An 82-year-old female with known hypothyroidism was admitted to hospital after being found on the floor. On examination, she was unkempt, confused, bradycardic, hypothermic, and barely arousable. Initial biochemistry revealed a thyroid stimulating hormone (TSH) of >100 mU/L and free thyroxine (FT4) level of 1.5 pmol/L which supported a diagnosis of myxoedema coma. She was resuscitated and commenced on liothyronine, levothyroxine, and hydrocortisone and some improvement was made. It became apparent that she was hiding and spitting out her oral levothyroxine including levothyroxine elixir. Given the need for prompt alternative control, we sought advice from international experts where intramuscular levothyroxine was recommended. She was managed from day 50 onwards with intramuscular levothyroxine 200 mcg once a week, which was subsequently increased to 500 mcg. Thyroid function normalized and she made continual cognitive and physical progress and was discharged to a rehabilitation hospital. Her intramuscular levothyroxine was stopped and she was subsequently restarted on oral levothyroxine, with a plan for on-going close monitoring of her thyroid function. This report highlights the potential to use intramuscular levothyroxine in individuals with severe hypothyroidism arising from poor compliance with levothyroxine treatment or other potential causes such as impaired absorption.

The use of combined oral contraceptives has been associated with an increased risk of adverse cardiovascular events. Whether these drugs alter cardiac autonomic nervous system control is not completely determined. To evaluate the effect of a contraceptive containing 20mcg of ethinyl estradiol and 3mg of drospirenone on the heart rate variability, baroreflex sensitivity and blood pressure of healthy women. Prospective controlled trial with 69 healthy women allocated in two groups: 36 volunteers under oral combined contraceptive use and 33 volunteers using of non-hormonal contraceptive methods. Subjects were tested before the introduction of the contraceptive method and 6 months after its use. For data acquisition, we used continuous non-invasive beat-to-beat blood pressure curve recordings. Multiple ANOVA was used to determine differences between groups and moments and p< 0.05 was considered statistically significant. At baseline, there were no differences in demographic and autonomic parameters between groups. Comparing cardiac sympatho-vagal modulation, baroreceptor sensitivity and blood pressure measurements between baseline and after 6 months, no significant difference was detected in each group or between groups. A contraceptive containing 20mcg of ethinyl estradiol and 3mg of drospirenone causes no significant changes in clinical, hemodynamic and autonomic parameters of normal women.

To determine the influence of oral hygiene habits and practices on the risk of developing oral leukoplakia. Case control study. Githongo sublocation in Meru District. Eighty five cases and 141 controls identified in a house-to-house screening. The relative risk (RR) of oral leukoplakia increased gradually across the various brushing frequencies from the reference RR of 1.0 in those who brushed three times a day, to 7.6 in the "don't brush" group. The trend of increase was statistically significant (X2 for Trend : p = 0.001). The use of chewing stick as compared to conventional tooth brush had no significant influence on RR of oral leukoplakia. Non-users of toothpastes had a significantly higher risk of oral leukoplakia than users (RR = 1.8; 95% confidence levels (CI) = 1.4-2.5). Among tobacco smokers, the RR increased from 4.6 in those who brushed to 7.3 in those who did not brush. Among non-smokers, the RR of oral leukoplakia in those who did not brush (1.8) compared to those who brushed was also statistically significant (95% CL = 1.6-3.8). Failure to brush teeth and none use of toothpastes are significantly associated with the development of oral leukoplakia, while the choice of brushing tools between conventional toothbrush and chewing stick is not. In addition, failure to brush teeth appeared to potentiate the effect of smoking tobacco in the development of oral leukoplakia. Oral health education, instruction and motivation for the improvement of oral hygiene habits and practices; and therefore oral hygiene status, should be among the strategies used in oral leukoplakia preventive and control programmes.

To test the safety, acceptability, feasibility, and effectiveness of community-based education and distribution of misoprostol for prevention of postpartum hemorrhage at home birth in Afghanistan. A nonrandomized experimental control design in rural Afghanistan. A total of 3187 women participated: 2039 in the intervention group and 1148 in the control group. Of the 1421 women in the intervention group who took misoprostol, 100% correctly took it after birth, including 20 women with twin pregnancies. Adverse effect rates were unexpectedly lower in the intervention group than in the comparison group. Among women in the intervention group, 92% said they would use misoprostol in their next pregnancy. In the intervention area where community-based distribution of misoprostol was introduced, near-universal uterotonic coverage (92%) was achieved compared with 25% coverage in the control areas. In Afghanistan, community-based education and distribution of misoprostol is safe, acceptable, feasible, and effective. This strategy should be considered for other countries where access to skilled attendance is limited.

Peginterferon beta-1a 125 mcg administered subcutaneously every 2 weeks, a new disease-modifying therapy (DMT) for relapsing-remitting multiple sclerosis (RRMS), was approved in January 2015 by the Scottish Medicines Consortium. This study assesses long-term clinical and economic outcomes of peginterferon beta-1a compared with other self-injectable DMTs (interferon beta-1a [22 mcg, 30 mcg, and 44 mcg], interferon beta-1b, and glatiramer acetate 20 mg) in the treatment of RRMS, from the National Health Service and Personal Social Services perspective in Scotland. A previously published, validated Markov cohort model was adapted for this analysis. The model estimates changes in patient disability, occurrence of relapses, and other adverse events, and translates them into quality-adjusted life years and costs. Natural history data came from the ADVANCE trial of peginterferon beta-1a, the London Ontario (Canada) database, and a large population-based MS survey in the UK. The comparative efficacy of each DMT vs placebo was obtained from a network meta-analysis. Costs (2015 British Pounds) were obtained from public databases and literature. Clinical and economic outcomes were projected over 30 years and discounted at 3.5% per year. Over 30 years, peginterferon beta-1a was dominant compared with interferon beta-1a (22, 30, and 44 mcg), and interferon beta-1b, and cost-effective compared with glatiramer acetate 20 mg. Results were most sensitive to variations in each DMT's efficacy and acquisition costs. Deterministic and probabilistic sensitivity analyses confirmed the robustness of the results. The impact of improved adherence with peginterferon beta-1a on clinical and economic outcomes and the impact of subsequent DMTs after treatment discontinuation were not considered. Oral and infused DMTs were not included as comparators. Conclusion Long-term treatment with peginterferon beta-1a improves clinical outcomes, while its cost profile makes it either

Induced abortion among Brazilian female sex workers: a qualitative study.

Madeiro, Alberto Pereira; Diniz, Debora

2015-02-01

Prostitutes are vulnerable to unplanned pregnancies and abortions. In Brazil, abortion is a crime and there is no data about unsafe abortions for this population. The study describes how prostitutes perform illegal abortions and the health consequences thereof. Semi-structured interviews with 39 prostitutes from three cities in Brazil with previous induced abortion experience were conducted. Sixty-six abortions, with between one and eight occurrences per woman, were recorded. The majority of the cases resulted from sexual activity with clients. The inconsistent use of condoms with regular clients and the consumption of alcohol during work were indicated as the main causes of unplanned pregnancies. The main method to perform abortion was the intravaginal and oral use of misoprostol, acquired in pharmacies or on the black market. Invasive measures were less frequently reported, however with more serious health complications. The fear of complaint to the police meant that most women do not inform the health team regarding induced abortion. The majority of prostitutes aborted with the use of illegally-acquired misoprostol, ending abortion in a public hospital with infection and hemorrhagic complications. The data indicate the need for a public policy focusing on the reproductive health of prostitutes.

There is scarce information available on oral health service utilization patterns and common oral hygiene practices among adult Nigerians. We conducted the 2010-2011 national oral health survey before the introduction of the national oral health policy to determine the prevalence of oral health service utilization, patterns of oral hygiene practices, and self reported oral health status, among adults in various social classes, educational strata, ethnic groups and geopolitical zones in Nigeria. We conducted a cross-sectional survey in North-Central, North-West, South-East, South-South and South-West geopolitical zones of Nigeria. Multi-stage cluster sampling method was used for the sample selection. We administered a structured questionnaire to a total of 7,630 participants. Information on the socio-demographic characteristics, oral hygiene practices and oral health services utilization pattern of participants was obtained. We interviewed 7, 630 participants (55.6% female). The participants ages ranged between 18 and 81 years, mean age was 37.96 (SD = 13.2). Overall 21.2% of the participants rated their oral health status as very good, 37.1% as good and 27.4% as fair. Only 26.4% reported having visited the dentist at least once prior to the conduct of the survey. More than half of these visits (54.9%) were for treatment purpose. Utilization of oral health services was significantly (p < 0.05) associated with being older, more educated and being engaged in a skilled profession. More educated persons, females and younger persons used toothbrushes for daily tooth cleaning. Age, sex, marital status, level of education and occupation were significantly related to daily frequency of tooth cleaning (p < 0.05). Our results show that while most Nigerian adults have a positive view of their oral health status, majority reported poor oral health utilization habits. Older persons resident in the northern zones of the country and less educated persons displayed

Early pregnancy failure (EPF) is a common complication of pregnancy. Surgical intervention carries a risk of complications and, therefore, medical treatment appears to be a safe alternative. Unfortunately, the current medical treatment with misoprostol alone has complete evacuation rates between 53% and 87%. Some reports suggest that sequential treatment with mifepristone and misoprostol leads to higher success rates than misoprostol alone. To evaluate the added value of mifepristone to current non-surgical treatment regimens in women with EPF we performed a systematic literature search. Electronic databases were searched: PubMed, Cochrane Library, Current Controlled Trials, and ClinicalTrials.gov. Clinical studies, both randomised and non-randomised trials, reporting on the added value of mifepristone to current non-surgical treatment regimens in women with EPF were included. Data of sixteen studies were extracted using a data extraction sheet (based on the Cochrane Consumers and Communication Review Group's data extraction template). The methodological quality was assessed using the Cochrane Collaboration Risk of Bias tool. In five randomised and eleven non-randomised trials, success rates of sequential treatment with mifepristone and misoprostol in case of EPF varied between 52% and 95%. Large heterogeneity existed in treatment regimens and comparators between studies. The existing evidence is insufficient to draw firm conclusions about the added value of mifepristone to misoprostol alone. A sufficiently powered randomised, double blinded placebo-controlled trial is urgently required to test whether, in EPF, the sequential combination of mifepristone with misoprostol is superior to misoprostol only.

As-yet-uncultivated oral bacteria: breadth and association with oral and extra-oral diseases

PubMed Central

Siqueira, José F.; Rôças, Isabela N.

2013-01-01

It has been shown that 40–60% of the bacteria found in different healthy and diseased oral sites still remain to be grown in vitro, phenotypically characterized, and formally named as species. The possibility exists that these as-yet-uncultivated bacteria play important ecological roles in oral bacterial communities and may participate in the pathogenesis of several oral infectious diseases. There is also a potential for these as-yet-uncultivated oral bacteria to take part in extra-oral infections. For a comprehensive characterization of physiological and pathogenic properties as well as antimicrobial susceptibility of individual bacterial species, strains need to be grown in pure culture. Advances in culturing techniques have allowed the cultivation of several oral bacterial taxa only previously known by a 16S rRNA gene sequence signature, and novel species have been proposed. There is a growing need for developing improved methods to cultivate and characterize the as-yet-uncultivated portion of the oral microbiome so as to unravel its role in health and disease.

This paper outlines the burden of oral diseases worldwide and describes the influence of major sociobehavioural risk factors in oral health. Despite great improvements in the oral health of populations in several countries, global problems still persist. The burden of oral disease is particularly high for the disadvantaged and poor population groups in both developing and developed countries. Oral diseases such as dental caries, periodontal disease, tooth loss, oral mucosal lesions and oropharyngeal cancers, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-related oral disease and orodental trauma are major public health problems worldwide and poor oral health has a profound effect on general health and quality of life. The diversity in oral disease patterns and development trends across countries and regions reflects distinct risk profiles and the establishment of preventive oral health care programmes. The important role of sociobehavioural and environmental factors in oral health and disease has been shown in a large number of socioepidemiological surveys. In addition to poor living conditions, the major risk factors relate to unhealthy lifestyles (i.e. poor diet, nutrition and oral hygiene and use of tobacco and alcohol), and limited availability and accessibility of oral health services. Several oral diseases are linked to noncommunicable chronic diseases primarily because of common risk factors. Moreover, general diseases often have oral manifestations (e.g. diabetes or HIV/AIDS). Worldwide strengthening of public health programmes through the implementation of effective measures for the prevention of oral disease and promotion of oral health is urgently needed. The challenges of improving oral health are particularly great in developing countries. PMID:16211157

Oral cancers are attributed to a number of causal agents including tobacco, alcohol, human papillomavirus (HPV), and areca (betel) nut. Although betel nut chewing has been established as an independent cause of oral cancer, the mechanisms of carcinogenesis are poorly understood. An investigation was undertaken to evaluate the influence of betel nut chewing on the oral microbiome and oral premalignant lesions. Study participants were recruited from a dental clinic in Guam. Structured interviews and oral examinations were performed. Oral swabbing and saliva samples were evaluated by 454 pyrosequencing of the V3- V5 region of the 16S rRNA bacterial gene and genotyped for HPV. One hundred twenty-two adults were enrolled including 64 current betel nut chewers, 37 former chewers, and 21 with no history of betel nut use. Oral premalignant lesions, including leukoplakia and submucous fibrosis, were observed in 10 chewers. Within-sample bacterial diversity was significantly lower in long-term (≥10 years) chewers vs. never chewers and in current chewers with oral lesions vs. individuals without lesions. Between-sample bacterial diversity based on Unifrac distances significantly differed by chewing status and oral lesion status. Current chewers had significantly elevated levels of Streptococcus infantis and higher and lower levels of distinct taxa of the Actinomyces and Streptococcus genera. Long-term chewers had reduced levels of Parascardovia and Streptococcus. Chewers with oral lesions had significantly elevated levels of Oribacterium, Actinomyces, and Streptococcus, including Streptococcus anginosus. In multivariate analyses, controlling for smoking, oral HPV, S.anginosus, and S. infantis levels, current betel nut chewing remained the only predictor of oral premalignant lesions. Our study provides evidence that betel nut chewing alters the oral bacterial microbiome including that of chewers who develop oral premalignant lesions. Nonetheless, whether microbial changes

To investigate the effects of daily chromium picolinate supplementation on serum measures of glucose tolerance and insulin sensitivity in patients at high risk for type 2 diabetes mellitus. We conducted a randomized, double-blind, placebo-controlled, modified cross-over clinical trial with 6-month sequences of intervention and placebo followed by a 6-month postintervention assessment. Adult patients with impaired fasting glucose, impaired glucose tolerance, or metabolic syndrome were enrolled. Participants received 6-month sequences of chromium picolinate or placebo at 1 of 2 dosages (500 or 1000 mcg daily). Primary outcome measures were change in fasting plasma glucose, 2-hour plasma glucose during oral glucose tolerance testing, fasting and 2-hour insulin, and homeostasis model assessment of insulin resistance (HOMA-IR). Secondary outcomes included anthropometric measures, blood pressure, endothelial function, hemoglobin A1c, lipids, and urinary microalbumin. Fifty-nine participants were enrolled. No changes were seen in glucose level, insulin level, or HOMA-IR (all P>.05) after 6 months of chromium at either dosage level (500 mcg or 1000 mcg daily) when compared with placebo. None of the secondary outcomes improved with either chromium dosage compared with placebo (P>.05). Chromium supplementation does not appear to ameliorate insulin resistance or impaired glucose metabolism in patients at risk for type 2 diabetes and thus is unlikely to attenuate diabetes risk.

Oral Microbiome: A New Biomarker Reservoir for Oral and Oropharyngeal Cancers

2017-01-01

Current biomarkers (DNA, RNA and protein) for oral cavity and oropharyngeal cancers demonstrate biological variations between individuals, rendering them impractical for clinical translation. Whilst these biomarkers originate from the host, there is not much information in the literature about the influence of oral microbiota on cancer pathogenesis, especially in oral cancers. Oral microbiotas are known to participate in disease initiation and progression not only limited to the oral cavity, but also at other distant sites. Due to the close proximity of oral microbiota and oral cavity and oropharyngeal tumours, abundance changes in oral microbiota may provide useful information on tumourigenesis. This review aims to highlight information on the role of oral microbiota in oral cavity and oropharyngeal cancers. An in-depth analysis into the oral microbiota may provide a new avenue to diagnose and treat these patients. PMID:29158828

To evaluate oral cancer-related screening practices of Oral Health Professionals (OHPs - dentists, dental hygienists, dental therapists, and oral health therapists) practising in Victoria, Australia. A 36-item survey was distributed to 3343 OHPs. Items included socio-demographic and work-related characteristics; self-assessed knowledge of oral cancer; perceived level of confidence in discussing oral health behaviors with patients; oral cancer screening practices; and self-evaluated need for additional training on screening procedures for oral cancer. A total of 380 OHPs responded this survey, achieving an overall response rate of 9.4%. Forty-five were excluded from further analysis. Of these 335 OHP, 72% were dentists; (n = 241); either GDP or Dental Specialists; 13.7% (n = 46) were dental hygienists; 12.2% (n = 41) were oral health therapists, and the remaining 2.1% (n = 7) were dental therapists. While the majority (95.2%) agreed that oral cancer screening should be routinely performed, in actual practice around half (51.4%) screened all their patients. Another 12.8% "Very rarely" conducted screening examinations. The probability of routinely conducting an oral cancer screening was explored utilising Logistic Regression Analysis. Four variables remained statistically significant (p < 0.0001). Results indicate that the likelihood of conducting an oral cancer screening rose with increasing levels of OHPs' confidence in oral cancer-related knowledge (OR = 1.35; 95% CI: 1.09-1.67) and with higher levels of confidence in discussing oral hygiene practices with patients (OR = 1.25; 95% CI: 1.03-1.52). Results also showed that dental specialists were less likely to perform oral cancer screening examinations compared with other OHPs (OR = 0.18; 95% CI: 0.07-0.52) and the likelihood of performing an oral cancer screening decreased when the "patient complained of a problem" (OR = 0.21; 95% CI: 0.10-0.44).

There is a substantial proportion of the population using fixed metallic oral appliances, such as crowns and bridges, which are composed of various dental alloys. These restorations may be associated with a number of effects on oral health with variable degrees of severity, to review potential effects of using fixed metallic oral appliances, fabricated from various alloys. The MEDLINE/PubMed database was searched using certain combinations of keywords related to the topic. The search revealed that burning mouth syndrome, oral pigmentation, hypersensitivity and lichenoid reactions, and genotoxic and cytotoxic effects are the major potential oral health changes associated with fixed prosthodontic appliances. Certain oral disorders are associated with the use of fixed metallic oral appliances. Patch test is the most reliable method that can be applied for identifying metal allergy, and the simultaneous use of different alloys in the mouth is discouraged.

[Oral microbiota: a promising predictor of human oral and systemic diseases].

PubMed

Xin, Xu; Junzhi, He; Xuedong, Zhou

2015-12-01

A human oral microbiota is the ecological community of commensal, symbiotic, and pathogenic microorganisms found in human oral cavity. Oral microbiota exists mostly in the form of a biofilm and maintains a dynamic ecological equilibrium with the host body. However, the disturbance of this ecological balance inevitably causes oral infectious diseases, such as dental caries, apical periodontitis, periodontal diseases, pericoronitis, and craniofacial bone osteomyelitis. Oral microbiota is also correlated with many systemic diseases, including cancer, diabetes mellitus, rheumatoid arthritis, cardiovascular diseases, and preterm birth. Hence, oral microbiota has been considered as a potential biomarker of human diseases. The "Human Microbiome Project" and other metagenomic projects worldwide have advanced our knowledge of the human oral microbiota. The integration of these metadata has been the frontier of oral microbiology to improve clinical translation. By reviewing recent progress on studies involving oral microbiota-related oral and systemic diseases, we aimed to propose the essential role of oral microbiota in the prediction of the onset, progression, and prognosis of oral and systemic diseases. An oral microbiota-based prediction model helps develop a new paradigm of personalized medicine and benefits the human health in the post-metagenomics era.

The oral cavity is inhibited by many of the bacterial species. Some of them have a key role in the development of oral disease. Interrelationships between oral microbiome and systemic conditions such as head-and-neck cancer have become increasingly appreciated in recent years. Emerging evidence also suggests a link between periodontal disease and oral cancer, and the explanation being that chronic inflammation could be a major factor in both diseases. Squamous cell carcinoma is that the most frequently occurring malignancy of the oral cavity and adjacent sites, representing over 90% of all cancers. The incidence of oral cancer is increasing, significantly among young people and women. Worldwide there are 350,000-400,000 new cases diagnosed every year. Bacteria, viruses, and fungi are strongly implicated as etiological factors in certain cancers. In this review we will discuss the association between the development of oral cancer in potentially malignant oral lesions with chronic periodontitis, chronic Porphyromonas gingivalis, Fusobacterium nucleatum, candida, other microbes and described mechanisms which may be involved in these carcinoma.

Strengthening of Oral Health Systems: Oral Health through Primary Health Care

PubMed Central

Petersen, Poul Erik

2014-01-01

Around the globe many people are suffering from oral pain and other problems of the mouth or teeth. This public health problem is growing rapidly in developing countries where oral health services are limited. Significant proportions of people are underserved; insufficient oral health care is either due to low availability and accessibility of oral health care or because oral health care is costly. In all countries, the poor and disadvantaged population groups are heavily affected by a high burden of oral disease compared to well-off people. Promotion of oral health and prevention of oral diseases must be provided through financially fair primary health care and public health intervention. Integrated approaches are the most cost-effective and realistic way to close the gap in oral health between rich and poor. The World Health Organization (WHO) Oral Health Programme will work with the newly established WHO Collaborating Centre, Kuwait University, to strengthen the development of appropriate models for primary oral health care.

incremental cost-effectiveness ratios, expected costs, utilities and net benefit. We represent uncertainty in the optimal intervention using cost-effectiveness acceptability curves. We identified 1190 studies; 611 were eligible for inclusion. The interventions most likely to achieve vaginal delivery (VD) within 24 hours were intravenous oxytocin with amniotomy [posterior rank 2; 95% credible intervals (CrIs) 1 to 9] and higher-dose (≥ 50 µg) vaginal misoprostol (rank 3; 95% CrI 1 to 6). Compared with placebo, several treatments reduced the odds of caesarean section, but we observed considerable uncertainty in treatment rankings. For uterine hyperstimulation, double-balloon catheter had the highest probability of being among the best three treatments, whereas vaginal misoprostol (≥ 50 µg) was most likely to increase the odds of excessive uterine activity. For other safety outcomes there were insufficient data or there was too much uncertainty to identify which treatments performed 'best'. Few studies collected information on women's views. Owing to incomplete reporting of the VD within 24 hours outcome, the cost-effectiveness analysis could compare only 20 interventions. The analysis suggested that most interventions have similar utility and differ mainly in cost. With a caveat of considerable uncertainty, titrated (low-dose) misoprostol solution and buccal/sublingual misoprostol had the highest likelihood of being cost-effective. There was considerable uncertainty in findings and there were insufficient data for some planned subgroup analyses. Overall, misoprostol and oxytocin with amniotomy (for women with favourable cervix) is more successful than other agents in achieving VD within 24 hours. The ranking according to safety of different methods was less clear. The cost-effectiveness analysis suggested that titrated (low-dose) oral misoprostol solution resulted in the highest utility, whereas buccal/sublingual misoprostol had the lowest cost. There was a high

This study aimed to determine the effectiveness of oral-hygiene instruction in improving oral health in 100 patients following oral hygiene instruction, with and without use of an intra-oral camera. The two groups of 50 patients were similar in age and sex distributions, frequency of caries, plaque accumulation and gingival bleeding. Prospective improvements in oral hygiene and compliance were measured by means of plaque levels and gingival bleeding at baseline and four weeks later. While both groups showed a clear reduction in plaque accumulation, the test group benefited from the use of the intra-oral camera. A majority of patients (88 per cent) thought that the extra information provided by the camera was helpful and desirable. This study demonstrates that the intra-oral camera can effectively augment oral-hygiene instruction and help create improvements in patient compliance.

Chronic obstructive pulmonary disease (COPD) is a complex and progressive respiratory disease characterized by incompletely reversible bronchial obstruction. The effects of current therapeutic options in early stages of COPD have been poorly investigated in the past, being this specific topic revamped by the results of recent secondary analyses from large international trials. To measure and monitor in real life the changes in main clinical outcomes and health care resources in patients suffering from mild-to-moderate and severe COPD treated with only tiotropium br. for twenty-four months. The population sample of the present observational retrospective study consists of 319 COPD subjects (214 males; average age 71.7 years ± 06 se) automatically extracted from the DataBase of the Health Care Institution. Inclusion criteria were: age ≥ 40 y; basal FEV1 < 80% predicted and FEV1/FVC < 70%; regular treatment with only 18 mcg tiotropium br. for the following two years. All subjects were divided into two subsets according to their FEV1 basal value: (Group A ≤ 50%, and Group B >50% predicted). Lung function; n. exacerbations; n. hospitalizations; absenteeism; n. GP's visits, and use of systemic steroids or antibiotics were checked during the observational period and mean values compared in both subsets with those of the twelve months preceding tiotropium br. (such as during other therapeutic strategies). T test was used for checking the comparability of groups, while ANOVA--Duncan test was used to compare the trends of all variables over time; p < 0.05 was accepted. Group A, 154 individuals (104 males; mean age 72.1 years ± 0.51 se) had a mean FEV1 value of 45.4% pred. ± 0.61 se, while the remaining 165, Group B (111 males; mean age 71.4 years ± 0.60 se) had a mean FEV1 value of 65.5% pred. ± 5.7 se (p < 0,01). The two subsets were well matched for gender, age, and previous use of systemic steroids, but significantly different in terms of basal lung function

It is important to evaluate the background of oral cavity biology to define morphologic abrasions in oral mucosa following a host of local and/ or systemic disorders. The oral cavity is not only the beginning of the digestive system, but it also plays a significant role in communication; the voice (although the voice is produced in the throat), tongue, lips, and jaw are its essential components to produce the range of sounds. The vestibule and the oral cavity are its major parts, and are usually moist. The lips and the teeth are in approximation, marking its start up. The anatomy of the oral cavity in brief has been reviewed in right prospective for disease related changed morphology, thus facilitating interpretation.

Opening a door to safe abortion: international perspectives on medical abortifacient use.

PubMed

Pollack, A E; Pine, R N

2000-01-01

International experience compels us to revisit how we define and assess the safety and efficacy of medical abortifacients such as misoprostol. In some countries where safe abortion is neither accessible nor legal, even unsupervised, off-protocol use of misoprostol can provide women with a means to safely terminate pregnancy. This is due primarily to misoprostol-induced uterine contractions that cause bleeding, which in turn provides access to existing reasonable quality health services that would otherwise be unavailable. Several studies have suggested that an increase in the underground use of misoprostol in Brazil has already reduced serious complications from unsafe abortion. Thus, the availability of medical abortifacients combined with strengthened postabortion care services can legitimately be considered a public health success in countries in which safe abortion services do not exist and law reform is unlikely.

Infants with diabetes insipidus (DI), especially those with impaired thirst mechanism or hypothalamic hyperphagia, are prone to severe sodium fluctuations, often requiring hospitalization. We aimed to avoid dangerous fluctuations in serum sodium and improve parental independence. A 16-month old girl with central DI, absent thirst mechanism and hyperphagia following surgery for hypothalamic astrocytoma had erratic absorption of oral DDAVP during chemotherapy cycles. She required prolonged hospitalizations for hypernatremia and hyponatremic seizure. Intensive monitoring of fluid balance, weight and clinical assessment of hydration were not helpful in predicting serum sodium. Discharge home was deemed unsafe. Oral DDAVP was switched to subcutaneous (twice-daily injections, starting with 0.01mcg/dose, increasing to 0.024mcg/dose). The parents adjusted daily fluid allocation by sliding-scale, according to the blood sodium level (measured by handheld i-STAT analyser, Abbott). We adjusted the DDAVP dose if fluid allocation differed from maintenance requirements for 3 consecutive days. After 2.5 months, sodium was better controlled, with 84% of levels within reference range (135-145 mmol/L) vs. only 51% on the old regimen (p = 0.0001). The sodium ranged from 132-154 mmol/L, compared to 120-156 on the old regimen. She was discharged home. This practical regimen improved sodium control, parental independence, and allowed discharge home.

Intrathecal (IT) pumps have become a valuable tool in managing intractable non-cancer pain. The purpose of this study was to evaluate the efficacy of using a rigorous treatment algorithm for trialing and implanting IT pumps with hydromorphone and bupivacaine in managing a more homogeneous population of post-laminectomy syndrome or failed back surgery syndrome (FBSS) patients. This is a retrospective analysis of FBSS patients with chronic intractable back pain implanted with IT pumps delivering hydromorphone and bupivacaine. A cohort of 57 (26 males, 31 females) consecutively implanted FBSS patients was analyzed. The average age at implant was 65.4 years. Average pain scores were 8.4 ± 0.2 (pre-implant), 4.9 ± 0.4 (6 months), 5.2 ± 0.5 (12 months), and 4.3 ± 0.5 (24 months). Average oral opioid doses in morphine equivalents were 56 ± 10 mg/day (pre-implant), 12.0 ± 3.5 mg/day (12 months), 15 ± 6 mg/day (24 months). Average IT hydromorphone doses were 79 ± 6.8 mcg/day (at implant), 184 ± 22 mcg/day (6 months), 329 ± 48 mcg/day (12 months), and 487 ± 80 mcg (24 months). IT hydromorphone dose escalation from baseline was 133% (6 months vs baseline), 78% (12 months vs 6 months), and 48% from 12 months to 24 months. Average IT bupivacaine doses were 5.8 ± 0.3 mg/day (implant), 9.5 ± 0.6 mg/day (6 months), 12.2 ± 0.7 mg/day (12 months), and 12.6 ± 0.9 mg/day (24 months). IT hydromorphone and bupivacaine are effective in treating chronic pain of FBSS, as demonstrated by the reduction of pain intensity and oral opioid consumption. However, an IT dose escalation phenomenon was observed, although at a reduced rate compared with what had been previously reported in the literature. It is possible that the local anesthetic combination delivered via a patient-activaed bolus device is an important factor. Despite demonstrating effectiveness, the clinical utility of myPTM-optimized IT therapy remains limited

For millions of years, our resident microbes have coevolved and coexisted with us in a mostly harmonious symbiotic relationship. We are not distinct entities from our microbiome, but together we form a 'superorganism' or holobiont, with the microbiome playing a significant role in our physiology and health. The mouth houses the second most diverse microbial community in the body, harbouring over 700 species of bacteria that colonise the hard surfaces of teeth and the soft tissues of the oral mucosa. Through recent advances in technology, we have started to unravel the complexities of the oral microbiome and gained new insights into its role during both health and disease. Perturbations of the oral microbiome through modern-day lifestyles can have detrimental consequences for our general and oral health. In dysbiosis, the finely-tuned equilibrium of the oral ecosystem is disrupted, allowing disease-promoting bacteria to manifest and cause conditions such as caries, gingivitis and periodontitis. For practitioners and patients alike, promoting a balanced microbiome is therefore important to effectively maintain or restore oral health. This article aims to give an update on our current knowledge of the oral microbiome in health and disease and to discuss implications for modern-day oral healthcare.

The purpose of this multicentre study was to determine the incidence of oral candidiasis in patients treated with topical steroids for oral lichen planus (OLP) and to determine whether the application of a concurrent antifungal therapy prevented the development of an oral candidiasis in these patients. Records of 315 patients with OLP seen at four Oral Medicine practices treated for at least 2 weeks with steroids with and without the use of an antifungal regimen were retrospectively reviewed. The overall incidence of oral fungal infection in those treated with steroid therapy for OLP was 13.6%. There was no statistically significant difference in the rate of oral candidiasis development in those treated with an antifungal regimen vs those not treated prophylactically (14.3% vs 12.6%) (P = 0.68). Despite the use of various regimens, none of the preventive antifungal strategies used in this study resulted in a significant difference in the rate of development of an oral candidiasis in patients with OLP treated with steroids. © 2015 John Wiley & Sons A/S.

2017-01-01

Oral cavity acts as a reservoir of bacterial pathogens for systemic infections and several oral microorganisms have been linked to systemic diseases. Quorum sensing and cyclic dinucleotides, two "decision-making" signaling systems, communicate to regulate physiological process in bacteria. Discovery of cyclic dinucleotides has a long history, but the progress in our understanding of how cyclic dinucleotides regulate bacterial lifestyle is relatively new. Oral microorganisms form some of the most intricate biofilms, yet c-di-GMP, and c-di-AMP signaling have been rarely studied in oral biofilms. Recent studies demonstrated that, with the aid of bacterial messenger molecules and their analogs, it is possible to activate host innate and adaptive immune responses and epithelial integrity with a dose that is relevant to inhibit bacterial virulence mechanisms, such as fimbriae and exopolysaccharide production, biofilm formation, and host cell invasion. The aim of this perspective article is to present available information on cyclic dinucleotides in oral bacteria and in oral biofilms. Moreover, technologies that can be used to detect cyclic dinucleotides in oral biofilms are described. Finally, directions for future research are highlighted.

The molecular complexity of the human oral cavity can only be clarified through identification of components that participate within it. However current proteomic techniques produce high volumes of information that are dispersed over several online databases. Collecting all of this data and using an integrative approach capable of identifying unknown associations is still an unsolved problem. This is the main motivation for this work. We present the online bioinformatic tool OralCard, which comprises results from 55 manually curated articles reflecting the oral molecular ecosystem (OralPhysiOme). It comprises experimental information available from the oral proteome both of human (OralOme) and microbial origin (MicroOralOme) structured in protein, disease and organism. This tool is a key resource for researchers to understand the molecular foundations implicated in biology and disease mechanisms of the oral cavity. The usefulness of this tool is illustrated with the analysis of the oral proteome associated with diabetes melitus type 2. OralCard is available at http://bioinformatics.ua.pt/oralcard.

The number of older people with dementia and a natural dentition is growing. Recently, a systematic review concerning the oral health of older people with dementia with the focus on diseases of oral hard tissues was published. To provide a comprehensive literature overview following a systematic approach of the level of oral hygiene and oral health status in older people with dementia with focus on oral soft tissues. A literature search was conducted in the databases PubMed, CINAHL, and the Cochrane Library. The following search terms were used: dementia and oral health or stomatognathic disease. A critical appraisal of the included studies was performed with the Newcastle-Ottawa scale (NOS) and Delphi list. The searches yielded 549 unique articles, of which 36 were included for critical appraisal and data extraction. The included studies suggest that older people with dementia had high scores for gingival bleeding, periodontitis, plaque, and assistance for oral care. In addition, candidiasis, stomatitis, and reduced salivary flow were frequently present in older people with dementia. The studies included in the current systematic review suggest that older people with dementia have high levels of plaque and many oral health problems related to oral soft tissues, such as gingival bleeding, periodontal pockets, stomatitis, mucosal lesions, and reduced salivary flow. With the aging of the population, a higher prevalence of dementia and an increase in oral health problems can be expected. It is of interest to have an overview of the prevalence of oral problems in people with dementia. Older people with dementia have multiple oral health problems related to oral soft tissues, such as gingival bleeding, periodontal pockets, mucosal lesions, and reduced salivary flow. The oral health and hygiene of older people with dementia is not sufficient and could be improved with oral care education of formal and informal caregivers and regular professional dental care to people

Influence of oral sex and oral cancer information on young adults' oral sexual-risk cognitions and likelihood of HPV vaccination.

Public health information and educational interventions regarding human papillomavirus (HPV) have focused on the link between vaginal sex and cervical cancer among women. Many people are unaware that HPV can be transmitted through oral sex or that HPV causes oral cancers. Given that HPV infections and unprotected oral sex are increasing, research on oral sex-related HPV risk is important. This study examined the effect of a brief informational intervention regarding HPV and oral sex on the sexual risk cognitions of young adults. College students (N = 238) read information on HPV, oral sex, and oral cancer or no information. Participants then completed measures of oral sex and HPV knowledge, oral sex willingness, HPV vaccination likelihood, and risk perceptions. Participants who read the information on HPV and oral sex and cancer (compared to those who did not) reported greater knowledge, perceived risk and concern, and lower willingness to engage in oral sex. These effects were only significant among women. However, men reported a higher likelihood of future HPV vaccination compared to women who had not yet received the vaccine. Focusing on oral sex and cancer, this study adds to research investigating ways to reduce HPV infections.

Expanding access to medication abortion through pharmacies is a promising avenue to reach women with safe and convenient care, yet no pharmacy provision interventions have been evaluated. This observational non-inferiority study investigated the effectiveness and safety of mifepristone-misoprostol medication abortion provided at pharmacies, compared to government-certified public health facilities, by trained auxiliary nurse-midwives in Nepal. Auxiliary nurse-midwives were trained to provide medication abortion through twelve pharmacies and public facilities as part of a demonstration project in two districts. Eligible women were ≤63 days pregnant, aged 16-45, and had no medical contraindications. Between 2014-2015, participants (n = 605) obtained 200 mg mifepristone orally and 800 μg misoprostol sublingually or intravaginally 24 hours later, and followed-up 14-21 days later. The primary outcome was complete abortion without manual vacuum aspiration; the secondary outcome was complication requiring treatment. We assessed risk differences by facility type with multivariable logistic mixed-effects regression. Over 99% of enrolled women completed follow-up (n = 600). Complete abortions occurred in 588 (98·0%) cases, with ten incomplete abortions and two continuing pregnancies. 293/297 (98·7%) pharmacy participants and 295/303 (97·4%) public facility participants had complete abortions, with an adjusted risk difference falling within the pre-specified 5 percentage-point non-inferiority margin (1·5% [-0·8%, 3·8%]). No serious adverse events occurred. Five (1.7%) pharmacy and two (0.7%) public facility participants experienced a complication warranting treatment (aRD, 0.8% [-1.0%-2.7%]). Early mifepristone-misoprostol abortion was as effective and safe when provided by trained auxiliary nurse-midwives at pharmacies as at government-certified health facilities.

Misoprostol is used for the medical management of miscarriage as it is more effective in the early stages of pregnancy. Letrozole has an anti-estrogen effect and is used for the pretreatment of miscarriage with misoprostol. The aim of this study was compare the efficacy and safety of letrozole with placebo pretreatment in the medical management of first trimester missed miscarriage. This was a prospective randomized case-control study. Four hundred and thirty-eight women were randomly divided into two groups of 219; the placebo group received placebo tablets twice daily for 3 days, followed by 800 micrograms of misoprostol vaginally on the fourth day of enrolment, while the letrozole group received letrozole 10 mg twice daily for three days followed by 800 micrograms misoprostol administered vaginally. Symptoms and side effects were recorded, and the women advised to return to hospital if they experienced severe pain or bleeding or intolerable side effects and to report to hospital for a check-up one week after misoprostol administration. Ultrasound was done seven days after misoprostol administration to monitor outcomes. Surgical evacuation was carried out if medical management failed. There were significant differences between the two groups, with better outcomes found for the letrozole group in terms of rates of complete miscarriage, onset of vaginal bleeding, and interval between induction and onset of expulsion (p < 0.001). A higher rate of nausea and vomiting was reported for the letrozole group (p = 0.002). Differences between groups with regard to pre- and post-termination hemoglobin levels, fever, severe pain and severe bleeding needing evacuation were not statistically significant. Adding letrozole to misoprostol improves the success rate and decreases the interval between induction and expulsion in cases of first trimester miscarriage; however, nausea and vomiting is higher with letrozole.

The objective was to assess the provision of the combination of mifepristone-misoprostol for menstrual regulation (MR) in randomly selected urban pharmacies in Bangladesh. We conducted a cross-sectional survey among 553 pharmacy workers followed by 548 mystery client visits to the same pharmacies in 3 municipal districts during July 2014-December 2015. The survey found that 99% of pharmacy workers visited had knowledge of MR procedures but only two-thirds (67%) could state the legal time limit correctly; they mentioned misoprostol (86%) over mifepristone-misoprostol combination (78%) as a procedure of MR with medication (MRM); 36% reported knowing the recommended dosage of mifepristone-misoprostol combination; 70% reported providing information on effectiveness of the medicines; 50% reported recommending at least one follow-up visit to them; 63% reported explaining possible complications of using the medications; and 47% reported offering any post-MR contraception to their clients. In contrast, mystery client visits found that the mifepristone-misoprostol combination (69%) was suggested over misoprostol (51%) by the pharmacy workers; 54% provided the recommended dosage of mifepristone-misoprostol combination; 42% provided information on its effectiveness; 12% recommended at least one follow-up visit; 11% counseled on possible complications; and only 5% offered post-MR contraceptives to the mystery clients. We found knowledge gaps regarding recommended dosage for MRM and inconsistent practice in informing women on effectiveness, follow-up visits, possible complications and provision of post-MR contraceptives among the pharmacy workers, particularly during the mystery client visits. Pharmacy workers in Bangladesh need to be trained on legal time limits for MR services provision, on providing accurate information on disbursed medicine, and on proper referral mechanisms. A strong monitoring and regulatory system for pharmacy provision of MRM in pharmacies should be

Huntington's disease (HD) patients and mouse models show learning and memory impairment even before the onset of motor symptoms. Deficits in hippocampal synaptic plasticity have been involved in the HD memory impairment. Several studies show that prostaglandin E2 (PGE2) EP2 receptor stimulates synaptic plasticity and memory formation. However, this role was not explored in neurodegenerative diseases. Here, we investigated the capacity of PGE2 EP2 receptor to promote synaptic plasticity and memory improvements in a model of HD, the R6/1 mice, by administration of the agonist misoprostol. We found that misoprostol increases dendritic branching in cultured hippocampal neurons in a brain-derived neurotrophic factor (BDNF)-dependent manner. Then, we implanted an osmotic mini-pump system to chronically administrate misoprostol to R6/1 mice from 14 to 18weeks of age. We observed that misoprostol treatment ameliorates the R6/1 long-term memory deficits as analyzed by the T-maze spontaneous alternation task and the novel object recognition test. Importantly, administration of misoprostol promoted the expression of hippocampal BDNF. Moreover, the treatment with misoprostol in R6/1 mice blocked the reduction in the number of PSD-95 and VGluT-1 positive particles observed in hippocampus of vehicle-R6/1 mice. In addition, we observed an increase of cAMP levels in the dentate ` of WT and R6/1 mice treated with misoprostol. Accordingly, we showed a reduction in the number of mutant huntingtin nuclear inclusions in the dentate gyrus of R6/1 mice. Altogether, these results suggest a putative therapeutic effect of PGE2 EP2 receptor in reducing cognitive deficits in HD. Copyright © 2016. Published by Elsevier Inc.

Oral cancer represents 2%-5% of all cancers, being one of the 10 most frequent ones. Apart from oral cancer risk factors already described in literature, such as tobacco and alcohol consumption, others emerging risk factors have been proposed, such as chronic irritation from dental factors. The aim of this work was to assess the influence of chronic trauma of the oral mucosa (CTOM) in patients with oral potentially malignant disorders (OPMD) and cancer. A retrospective study of 406 patients (both sexes; aged between 18 and 80 years; with OPMD and cancer) who attended the Department of Clinical Stomatology A of the National University of Cordoba was performed by non-probabilistic sampling. The association of variables and outcome variable diagnosis, with levels control, OPMD, oral cancer, was evaluated by multinomial regression model. Population under study was represented by 72% of control patients, 16% patients with OPMD and 11% of patients with oral cancer. It was observed a significant association between diagnosis and CTOM (P = 0.000), after adjustment of confounding factors (smoking and drinking habits, sex, cancer inheritance and denture use). Our results suggest that CTOM is, together with other factors, an important risk factor in patients with oral cancer diagnosis, but not for patients with OPMD.

Genodermatoses refers to group of inherited monogenic disorders with skin manifestations. Many of these disorders are rare and also have oral manifestations, called oral genodermatoses. This article provides a focused review of molecular basis of important genodermatoses that affects the oral cavity and also have prominent associated dermatologic features. In several conditions discussed here, the oral findings are distinct and may provide the first clue of an underlying genetic diagnosis. The article also emphasises on the prenatal diagnosis, genetic counselling and the treatment oral genodermatoses. PMID:27437377

Preterm infants (< 37 weeks' postmenstrual age) are often delayed in attaining oral feeding. Normal oral feeding is suggested as an important outcome for the timing of discharge from the hospital and can be an early indicator of neuromotor integrity and developmental outcomes. A range of oral stimulation interventions may help infants to develop sucking and oromotor co-ordination, promoting earlier oral feeding and earlier hospital discharge. To determine the effectiveness of oral stimulation interventions for attainment of oral feeding in preterm infants born before 37 weeks' postmenstrual age (PMA).To conduct subgroup analyses for the following prespecified subgroups.• Extremely preterm infants born at < 28 weeks' PMA.• Very preterm infants born from 28 to < 32 weeks' PMA.• Infants breast-fed exclusively.• Infants bottle-fed exclusively.• Infants who were both breast-fed and bottle-fed. We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed (1966 to 25 February 2016), Embase (1980 to 25 February 2016) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to 25 February 2016). We searched clinical trials databases, conference proceedings and the reference lists of retrieved articles. Randomised and quasi-randomised controlled trials comparing a defined oral stimulation intervention with no intervention, standard care, sham treatment or non-oral intervention in preterm infants and reporting at least one of the specified outcomes. One review author searched the databases and identified studies for screening. Two review authors screened the abstracts of these studies and full-text copies when needed to identify trials for inclusion in the review. All review authors independently extracted the data and analysed each study for risk of bias across the five domains of bias. All review authors discussed and analysed the data and

Few data exist on oral human papillomavirus (HPV) prevalence in female sex workers (FSWs). Information regarding oral sex practices of 185 Peruvian FSWs, 18-26 years of age, was obtained via survey and compared with HPV testing results of oral rinse samples. Oral HPV prevalence was 14/185 (7.6%); four (28.9%) HPV genotypes were carcinogenic. One hundred and eighty-two participants reported having had oral sex; 95% reported condom use during oral sex with clients and 9.5% with partners. Women who had oral sex more than three times with their partners in the past month were more likely to have oral HPV than women who had oral sex three times or less (P = 0.06). Ten (71.4%) women with oral HPV were HPV-positive at the cervix; conversely 8.3% of women with cervical HPV were HPV-positive in the oral cavity. The prevalence of oral HPV was relatively low, considering the high rates of oral sex practiced by these women.

Interviews were conducted with 294 black residents (155 females and 138 males) of a peri-urban informal settlement in Gauteng to ascertain utilisation of oral health services, oral health needs and oral health status. Only 37 per cent of the sample had consulted a dentist or medical practitioner, usually for extractions. Teenagers and employed persons were significantly less likely to utilise dentists than the older age groups and unemployed persons. Forty per cent were currently experiencing oral health problems such as a sore mouth, tooth decay and bleeding/painful gums. Two hundred and twelve (73 per cent) interviewees wanted dental treatment or advice. Residents who rated their oral health status as fair or poor appeared to have the greatest need for oral health services. The use of interviews appears to be a cost-effective method of determining oral morbidity.

42 pediatric patients with iron overload, who underwent liver biopsy and DFX treatment after hematopoietic stem cell transplantation were included in the study group. The patients were divided into two groups diversified according to deferasirox trough plasma concentrations (DFX C trough ) with cut-off equal to10 mcg/mL. The average dose of DFX was 25.9 mg/kg in the DFX C trough < 10 mcg/mL group versus 19.2 mg/kg in the DFX C trough > 10 mcg/mL group ( p =0,0003). The mean duration of DFX treatment was 135.7 days in the DFX C trough < 10 mcg/mL group versus 41.8 days in the DFX C trough > 10 mcg/mL group ( p <0.0001). The mean tissue iron concentration in the DFX C trough < 10 mcg/mL group was 261.9 μmol/g versus 133.4 μmol/g in the DFX C trough > 10 mcg/mL group ( p < 0.0001). 21 patients (100%) in the DFX C trough > 10 mcg/mL group had ductopenia which was complete in 47.6% of them and severe in 52.4%. All patients with particularly high C trough (> 25 mcg/mL) were found to have total ductopenia. 90.5% of all deferasirox-related adverse events and 100% of major adverse events occurred in the DFX C trough > 10 mcg/mL group. In the DFX C trough < 10 mcg/mL group only one patient interrupted chelation therapy versus 16 (84.2%) patients in the DFX C trough > 10 mcg/mL group. We would recommend a close monitoring in pediatric hematopoietic transplant recipients subjected to deferasirox-based therapy because we have observed a high incidence of adverse events and discontinuation of chelation treatment.

Summary The global spread of human immunodeficiency virus (HIV) is dependent on the ability of this virus to efficiently cross from one host to the next by traversing a mucosal membrane. Unraveling how mucosal exposure of HIV results in systemic infection is critical for the development of effective therapeutic strategies. This review focuses on understanding the immune events associated with the oral route of transmission (via breastfeeding or sexual oral intercourse), which occurs across the oral and/or gastrointestinal mucosa. Studies in both humans and simian immunodeficiency virus (SIV) monkey models have identified viral changes and immune events associated with oral HIV/SIV exposure. This review covers our current knowledge of HIV oral transmission in both infants and adults, the use of SIV models in understanding early immune events, oral immune factors that modulate HIV/SIV susceptibility (including mucosal inflammation), and interventions that may impact oral HIV transmission rates. Understanding the factors that influence oral HIV transmission will provide the foundation for developing immune therapeutic and vaccine strategies that can protect both infants and adults from oral HIV transmission.

This study aimed to assess: (1) oral symptoms of patients treated for oral or oropharyngeal cancer; (2) how patients rank the burden of oral symptoms; (3) the impact of the tumor, the treatment, and oral symptoms on functional outcome. Eighty-nine patients treated for oral or oropharyngeal cancer were asked about their oral symptoms related to mouth opening, dental status, oral sensory function, tongue mobility, salivary function, and pain. They were asked to rank these oral symptoms according to the degree of burden experienced. The Mandibular Function Impairment Questionnaire (MFIQ) was used to assess functional outcome. In a multivariate linear regression analyses, variables related to MFIQ scores (p≤0.10) were entered as predictors with MFIQ score as the outcome. Lack of saliva (52%), restricted mouth opening (48%), and restricted tongue mobility (46%) were the most frequently reported oral symptoms. Lack of saliva was most frequently (32%) ranked as the most burdensome oral symptom. For radiated patients, an inability to wear a dental prosthesis, a T3 or T4 stage, and a higher age were predictive of MFIQ scores. For non-radiated patients, a restricted mouth opening, an inability to wear a dental prosthesis, restricted tongue mobility, and surgery of the mandible were predictive of MFIQ scores. Lack of saliva was not only the most frequently reported oral symptom after treatment for oral or oropharyngeal cancer, but also the most burdensome. Functional outcome is strongly influenced by an inability to wear a dental prosthesis in both radiated and non-radiated patients.

Although adult attachment theory has been revealed as a useful theoretical framework for understanding a range of health parameters, the associations between adult attachment patterns and a range of oral health parameters have not yet been examined. The aim of this study was to examine potential associations between attachment insecurity and: (1) oral health-related quality of life (OHRQoL), (2) oral health behaviours, and (3) self-rated oral health. In association with this aim, sample characteristics were compared with normative data. The sample in this cross-sectional study was comprised of 265 healthy adults, recruited via convenience sampling. Data were collected on attachment patterns (Experiences in Close Relationships Scale-Short Form, ECR-S), OHRQoL (Oral Health Impact Profile-14, OHIP-14), oral health behaviours (modified Dental Neglect Scale, m-DNS), and self-rated oral health (one-item global rating of oral health). Multivariate regression models were performed. Both dimensions of attachment insecurity were associated with lowered use of favourable dental visiting behaviours, as well as decreased OHRQoL for both overall well-being and specific aspects of OHRQoL. Attachment avoidance was linked with diminished self-rated oral health. This study supports the potential value of an adult attachment framework for understanding a range of oral health parameters. The assessment of a client's attachment pattern may assist in the identification of people who are at risk of diminished OHRQoL, less adaptive dental visiting behaviours, or poorer oral health. Further research in this field may inform ways in which attachment approaches can enhance oral health-related interventions.

Objectives: The aim of this study was to evaluate the immunoexpression of TWIST and p-Akt proteins in oral leukoplakia (OL) and oral squamous cell carcinoma (OSCC), correlating their expressions with the histological features of the lesions. Study design: Immunohistochemical studies were carried out on 10 normal oral epithelium, 30 OL and 20 OSCC formalin-fixed, paraffin-embedded tissue samples. Immunoperoxidase reactions for TWIST and p-Akt proteins were applied on the specimens and the positivity of the reactions was calculated for 1000 epithelial cells. Results: Kruskal-Wallis and Dunn’s post tests revealed a significant difference in TWIST and p-Akt immunoexpression among normal oral mucosa, OL and OSCC. In addition, a significant positive correlation was found between TWIST and p-Akt expressions according to the Pearson’s correlation test. Conclusions: The results obtained in the current study suggest that TWIST and p-Akt may participate of the multi-step process of oral carcinogenesis since its early stages. Key words: Oral cancer, oral leukoplakia, dysplasia, immunohistochemistry. PMID:21743395

Background Pharmacokinetic (PK) parameters based on short sampling times (48 h or less) may contain inaccuracies due to their dependency on extrapolated values. This study was designed to measure PK parameters with greater accuracy in obese users of a low-dose oral contraceptive (OC), and to correlate drug levels with assessments of end-organ activity. Study design Obese (BMI ≥30 kg/m2), ovulatory, otherwise healthy, women (n = 32) received an OC containing 20 mcg ethinyl estradiol (EE)/100 mcg levonorgestrel (LNG) for two cycles. EE and LNG PK parameters were characterized for 168 h at the end of Cycle 1. During Cycle 2, biweekly outpatient visits were performed to assess cervical mucus, monitor ovarian activity with transvaginal ultrasound, and obtain serum samples to measure EE, LNG, estradiol (E2), and progesterone (P) levels. PK parameters were calculated and correlated with end-organ activity and compared against control samples obtained from normal and obese women sampled up to 48 h in a previous study. Standard determination of PK accuracy was performed; defined by the dependency on extrapolated values (‘excess’ area under the curve of 25% or less). Results The mean BMI was 39.4 kg/m2 (SD 6.6) with a range of 30–64 kg/m2. Key LNG PK parameters were as follows: clearance 0.52 L/h (SD 0.24), half-life 65 h (SD 40), AUC 232 h*ng/mL (SD 102) and time to reach steady-state 13.6 days (SD 8.4). The majority of subjects had increased ovarian activity with diameter of follicles ≥8 mm (n = 25) but only seven women had follicles ≥10 mm plus cervical mucus scores ≥5. Evidence of poor end-organ suppression did not correlate with the severity of the alterations in PK. As compared to historical normal and obese controls (48 h PK sampling), clearance, half-life, area under the curve (AUC) and time to reach steady-state were found to be significantly different (p ≤ 0.05) in obese women undergoing a longer duration of PK sampling (168 h).

Chlormadinone acetate (CMA) is a progestin compound similar to progesterone, with antiandrogenic properties. In healthy eumenorrheic women, it was demonstrated that the monophasic estroprogestin formulation containing CMA (2 mg) plus ethinyl estradiol (EE) (30 mcg) (EE30+CMA) is efficacious both in reducing hyperandrogenic symptoms, fat mass and in improving lipoprotein panel, without changes in insulin-glucose metabolism. These metabolic properties are important for women affected by polycystic ovary syndrome (PCOS) in whom there is a predisposition to insulin resistance. We studied whether in young nonobese women with PCOS (15 subjects, EE30+CMA-PCOS group) a six-cycle treatment with EE30+CMA can reduce androgen levels, androgen bioavailability and the score of hirsutism and acne, and modify glucose-insulin metabolism evaluated by the oral glucose tolerance test and the body composition evaluated by bio-impedenziometry. These parameters were evaluated before (first visit) and during the sixth cycle of EE30+CMA (second visit). All the results were compared with those of a matched-age-group of nonobese PCOS women (15 subjects, no OC-PCOS group) evaluated before (first visit) and after six menstrual cycles in which they did not use any drug or oral contraceptive (second visit). In the EE30+CMA-PCOS group women, androgen levels and bioavailability, hirsutism and acne score were significantly lower at the second than at the first visit, whereas they did not change in no OC-PCOS group. At the second visit, in both groups, glucose-insulin metabolism and body composition parameters were not affected. A six-cycle treatment with EE30+CMA is efficacious in nonobese PCOS women to improve hyperandrogenic symptoms, without negative interferences both on body composition and on insulin-glucose metabolism.

Integration of non-oral bacteria into in vitro oral biofilms.

PubMed

Thurnheer, Thomas; Belibasakis, Georgios N

2015-01-01

Biofilms are polymicrobial communities that grow on surfaces in nature. Oral bacteria can spontaneously form biofilms on the surface of teeth, which may compromise the health of the teeth, or their surrounding (periodontal) tissues. While the oral bacteria exhibit high tropism for their specialized ecological niche, it is not clear if bacteria that are not part of the normal oral microbiota can efficiently colonize and grow within oral biofilms. By using an in vitro "supragingival" biofilm model of 6 oral species, this study aimed to investigate if 3 individual bacterial species that are not part of the normal oral microbiota (Eschericia coli, Staphylococcus aureus, Enterococcus faecails) and one not previously tested oral species (Aggregatibacter actinomycetemcomitans) can be incorporated into this established supragingival biofilm model. Staphylococcus aureus and A. actinomycetemcomitans were able to grow efficiently in the biofilm, without disrupting the growth of the remaining species. They localized in sparse small aggregates within the biofilm mass. Enterococcus faecalis and E. coli were both able to populate the biofilm at high numbers, and suppressed the growth of A. oris and S. mutants. Enterococcus faecalis was arranged in a chain-like conformation, whereas E. coli was densely and evenly spread throughout the biofilm mass. In conclusion, it is possible for selected species that are not part of the normal oral microbiota to be introduced into an oral biofilm, under the given experimental micro-environmental conditions. Moreover, the equilibrated incorporation of A. actinomycetemcomitans and S. aureus in this oral biofilm model could be a useful tool in the study of aggressive periodontitis and peri-implantitis, in which these organisms are involved, respectively.

The oral microbiome can alter the balance between health and disease, locally and systemically. Within the oral cavity, bacteria, archaea, fungi, protozoa, and viruses may all be found, each having a particular role, but strongly interacting with each other and with the host, in sickness or in health. A description on how colonization occurs and how the oral microbiome dynamically evolves throughout the host's life is given. In this chapter the authors also address oral and nonoral conditions in which oral microorganisms may play a role in the etiology and progression, presenting the up-to-date knowledge on oral dysbiosis as well as the known underlying pathophysiologic mechanisms involving oral microorganisms in each condition. In oral pathology, oral microorganisms are associated with several diseases, namely dental caries, periodontal diseases, endodontic infections, and also oral cancer. In systemic diseases, nonoral infections, adverse pregnancy outcomes, cardiovascular diseases, and diabetes are among the most prevalent pathologies linked with oral cavity microorganisms. The knowledge on how colonization occurs, how oral microbiome coevolves with the host, and how oral microorganisms interact with each other may be a key factor to understand diseases etiology and progression.

Current oral assessment scales are designed to assess the severity of oral health in cancer patients who have undergone radiotherapy or chemotherapy. Currently, no scale is available that assesses the overall oral health situation of patients. However, this type of scale is critical for guiding nursing staff to understand the oral status of postoperative patients and for facilitating the development of patient-centered oral nursing treatments. To develop the oral assessment scale for post-operational patients with oral cancer (OASPOCa) and establish its psychometric properties. The ten associated items of the OASPOCa were determined using a series of five professional council meetings and two verifications of content validity by 5 experts in the field of oral cancer care. A pilot study was conducted on 30 participants and a formal study was conducted on 100 participants at the ICU and the oral and maxillofacial surgery ward at a medical center in southern Taiwan. All of the participants were oral cancer patients who had been admitted to excise tumors of oral cancer. None of the participants had been treated previously for oral cancer using chemotherapy or radiotherapy. The intraclass correlation coefficient (ICC), internal consistency reliability, and concurrent validity of the OASPOCa were evaluated. A content validity of 1.0 was obtained. The inter-rater reliability assessment in the pilot study yielded ICCs of .97 for two assessment items ("lips" and "tongue") and 1.0 for the remaining eight items. The Cronbach's α coefficient was .72 for the OASPOCa. Further, a statistically significant negative relationship was found between overall oral status and oral comfort level (r = -.93, p < .001). The oral assessment scale for post-operational patients with oral cancer was found to have good reliability and validity. This scale is a reliable tool for assessing the oral status of postoperative oral cancer patients.

The general dentist is sometimes confronted with white lesions of the oral mucosa. Oral lichen planus is the most common oral white lesion. The diagnosis can usually be made on the basis of the clinical aspect, but is sometimes made more difficult by certain abnormalities in the oral mucosa which clinically resemble oral lichen planus or by abnormalities which cannot be distinguished from oral lichen planus but have a different origin. Those lesions are classified as oral lichenoid lesions. Malignant deterioration has been described in allforms of oral lichen planus lesions and oral lichenoid lesions. There is no known method to predict or prevent malignant transformation. Nor are there any studies examining the efficacy of frequent follow-up visits. It seems sensible, in keeping with the tendency in recent literature, to schedule annual check-ups for patients to be on the safe side. These follow-up visits may reasonably be performed in a general dental practice.

Oral cancer in Chile corresponds approximately to 1.6% of all cancer cases. There are few studies about oral epithelial dysplasia and oral squamous cell carcinoma in the Chilean population. To determine the frequency of hyperkeratosis, mild, moderate and severe oral epithelial dysplasia, in situ carcinoma and squamous cell carcinoma of the oral and oropharyngeal mucosa in a registry of the Oral Pathology Reference Institute of the Faculty of Dentistry, Universidad de Chile, in a ten years period. Review of clinical records and pathological plates of 389 patients, obtained between 1990 and 2009. Cases were selected according to their pathological diagnosis, including hyperkeratosis, oral epithelial dysplasia, in situ carcinoma, squamous cell carcinoma and verrucous carcinoma. Forty four percent of cases were squamous cell carcinoma, followed by hyperkeratosis in 37% and mild epithelial dysplasia in 11%. Squamous cell carcinoma was more common in men aged over 50 years. Most of the potentially malignant disorders presented clinically as leukoplakia and squamous cell carcinoma were clinically recognized as cancer. In this study, men aged over 50 years are the highest risk group for oral cancer. Early diagnosis is deficient since most of these lesions were diagnosed when squamous cell carcinoma became invasive. Leukoplakia diagnosis is mostly associated with hyperkeratosis and epithelial dysplasia, therefore biopsy of these lesions is mandatory to improve early diagnosis.

The purpose of this study was to analyze the relationship between oral bacterial colonization and oral motor dysfunction. Oral motor dysfunction (swallowing and speech disorders) and detection of oral bacterial species from dental plaque in 55 elderly persons who had remained hospitalized for more than 3 months were investigated and statistically analyzed. The detection rates of methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Streptococcus agalactiae, and Stenotrophomonas maltophilia were significantly higher in subjects with than in those without a swallowing disorder. A similar result was found with regard to the presence of a speech disorder. About half of subjects who had oral motor dysfunction and hypoalbuminemia had colonization by MRSA and/or Pseudomonas aeruginosa. These results suggest that the combination of oral motor dysfunction and hypoalbminemia elevated the risk of opportunistic microorganisms colonization in the oral cavity of elderly patients hospitalized over the long term.

While human immunodeficiency virus (HIV) transmission through the adult oral route is rare, mother-to-child transmission (MTCT) through the neonatal/infant oral and/or gastrointestinal route is common. To study the mechanisms of cell-free and cell-associated HIV transmission across adult oral and neonatal/infant oral/intestinal epithelia, we established ex vivo organ tissue model systems of adult and fetal origin. Given the similarity of neonatal and fetal oral epithelia with respect to epithelial stratification and density of HIV-susceptible immune cells, we used fetal oral the epithelium as a model for neonatal/infant oral epithelium. We found that cell-free HIV traversed fetal oral and intestinal epithelia and infected HIV-susceptible CD4+ T lymphocytes, Langerhans/dendritic cells, and macrophages. To study the penetration of cell-associated virus into fetal oral and intestinal epithelia, HIV-infected macrophages and lymphocytes were added to the surfaces of fetal oral and intestinal epithelia. HIV-infected macrophages, but not lymphocytes, transmigrated across fetal oral epithelia. HIV-infected macrophages and, to a lesser extent, lymphocytes transmigrated across fetal intestinal epithelia. In contrast to the fetal oral/intestinal epithelia, cell-free HIV transmigration through adult oral epithelia was inefficient and virions did not infect intraepithelial and subepithelial HIV-susceptible cells. In addition, HIV-infected macrophages and lymphocytes did not transmigrate through intact adult oral epithelia. Transmigration of cell-free and cell-associated HIV across the fetal oral/intestinal mucosal epithelium may serve as an initial mechanism for HIV MTCT. PMID:22205732

Nonspeech Oral Movements and Oral Motor Disorders: A Narrative Review.

PubMed

Kent, Ray D

2015-11-01

Speech and other oral functions such as swallowing have been compared and contrasted with oral behaviors variously labeled quasispeech, paraspeech, speechlike, and nonspeech, all of which overlap to some degree in neural control, muscles deployed, and movements performed. Efforts to understand the relationships among these behaviors are hindered by the lack of explicit and widely accepted definitions. This review article offers definitions and taxonomies for nonspeech oral movements and for diverse speaking tasks, both overt and covert. Review of the literature included searches of Medline, Google Scholar, HighWire Press, and various online sources. Search terms pertained to speech, quasispeech, paraspeech, speechlike, and nonspeech oral movements. Searches also were carried out for associated terms in oral biology, craniofacial physiology, and motor control. Nonspeech movements have a broad spectrum of clinical applications, including developmental speech and language disorders, motor speech disorders, feeding and swallowing difficulties, obstructive sleep apnea syndrome, trismus, and tardive stereotypies. The role and benefit of nonspeech oral movements are controversial in many oral motor disorders. It is argued that the clinical value of these movements can be elucidated through careful definitions and task descriptions such as those proposed in this review article.

This paper analyzes the illegal trade in misoprostol, the medication predominantly used for abortion in Brazil. The study analyzed ten cases that came to the attention of the Public Prosecution Service for the Federal District between 2004 and 2010. The cases were organized into three categories: 1. women's stories; 2. profile of the vendors; 3. maternal mortality cases. The research was reviewed by an ethics committee. The main outcomes were: 1. young women in steady relationships use misoprostol in the home or with the assistance of drug vendors. Of the seven women indicted, three were reported on arrival at the public hospital to finalize abortion; 2. the drug vendors work at the community drugstore and are local agents for the sale of misoprostol. They instruct women on how to use the drug and how to prevent infections, but refuse to provide them with care in case of emergency. Traffickers operate via the internet and have a larger inventory of drugs; 3. there were two cases of maternal mortality due to the combination of high risk methods, such as a vaginal probe and misoprostol. The main causes for maternal mortality are the delay in seeking medical care, as the women fear criminal prosecution, and the combined use of misoprostol with high risk methods.

In the era of applied meta-omics and personalized medicine, the oral microbiome is a valuable asset. From biomarker discovery to being a powerful source of therapeutic targets and to presenting an opportunity for developing non-invasive approaches to health care, it has become clear that oral microbes may hold the answer for understanding disease, even beyond the oral cavity. Although our understanding of oral microbiome diversity has come a long way in the past 50 years, there are still many areas that need to be fine-tuned for better risk assessment and diagnosis, especially in early developmental stages of human life. Here, we discuss the factors that impact development of the oral microbiome and explore oral markers of disease, with a focus on the early oral cavity. Our ultimate goal is to put different experimental and methodological views into perspective for better assessment of early oral and systemic disease at an early age and discuss how oral microbiomes-at the community level-could provide improved assessment in individuals and populations at risk.

This article describes the essential components of oral health information systems for the analysis of trends in oral disease and the evaluation of oral health programmes at the country, regional and global levels. Standard methodology for the collection of epidemiological data on oral health has been designed by WHO and used by countries worldwide for the surveillance of oral disease and health. Global, regional and national oral health databanks have highlighted the changing patterns of oral disease which primarily reflect changing risk profiles and the implementation of oral health programmes oriented towards disease prevention and health promotion. The WHO Oral Health Country/Area Profile Programme (CAPP) provides data on oral health from countries, as well as programme experiences and ideas targeted to oral health professionals, policy-makers, health planners, researchers and the general public. WHO has developed global and regional oral health databanks for surveillance, and international projects have designed oral health indicators for use in oral health information systems for assessing the quality of oral health care and surveillance systems. Modern oral health information systems are being developed within the framework of the WHO STEPwise approach to surveillance of noncommunicable, chronic disease, and data stored in the WHO Global InfoBase may allow advanced health systems research. Sound knowledge about progress made in prevention of oral and chronic disease and in health promotion may assist countries to implement effective public health programmes to the benefit of the poor and disadvantaged population groups worldwide.

The focus was on haloperidol (central dopamine antagonist)-stomach lesion, a longly described suitable counterpart of dopamine blocker cysteamine-duodenal lesion. In this, the contribution of blockade of central/peripheral dopamine receptors and prostaglandins synthesis, along with influence of antiulcer agents was evaluated in mice. Male NMRI Hannnover mice were sacrificed 24 h after haloperidol (25 mg/kg b.w. i.p., given alone or with saline (haloperidol+saline) (i) or in combination (ii,iii)). Supporting central dopamine predominance for haloperidol stomach lesion induction, co-administration of peripheral dopamine receptor antagonist domperidone (5 mg/kg i.p.) (haloperidol+ domperidone) (ii), or prostaglandin synthesis inhibitor indomethacin (10 mg/kg s.c.) (haloperidol+ indomethacin) (iii) did not aggravate this lesion. (i) In haloperidol+saline challenged mice the lesions were inhibited by co-administration (/kg i.p.) of a gastric pentadecapeptide BPC 157, GlyGluProProProGlyLysProAlaAspAspAlaGlyLeuVal, M.W. 1419 (10 microg, 10 ng, 10 pg, but not 1 pg, 100 fg, 10 fg), bromocriptine (10 mg), omeprazole (10 mg, 100 mg, but not 1 mg). Atropine (10, 100, 200 mg), pirenzepine (10, 100, 200 mg), misoprostol (10, 100, 200 microg), pantoprazole (1, 10, 100 mg), lansoprazole (0.1, 1, 10 mg), cimetidine (10, 100, 200 mg) and ranitidine (10, 100, 200 mg) were not effective. (ii) Dopamine peripheral blockade influence: in haloperidol+domperidone mice, previously effective bromocriptine, pentadecapeptide BPC 157 (10 microg) or omeprazole (10 mg) did not attenuate stomach lesions. (iii) Prostaglandins synthesis blockade effect: in haloperidol+indomethacin mice, previously effective agents, bromocriptine or omeprazole were not active, while BPC 157 effect was only lessened.

We recently performed proteomic characterization of a modified collagen gel (MCG) dressing and reported promising effects of the gel in healing full-thickness excisional wounds. In this work, we test the translational relevance of our aforesaid findings by testing the dressing in a swine model of chronic ischemic wounds recently reported by our laboratory. Full-thickness excisional wounds were established in the center of bipedicle ischemic skin flaps on the backs of animals. Ischemia was verified by laser Doppler imaging, and MCG was applied to the test group of wounds. Seven days post wounding, macrophage recruitment to the wound was significantly higher in MCG-treated ischemic wounds. In vitro, MCG up-regulated expression of Mrc-1 (a reparative M2 macrophage marker) and induced the expression of anti-inflammatory cytokine interleukin (IL)-10 and of fibroblast growth factor-basic (β-FGF). An increased expression of CCR2, an M2 macrophage marker, was noted in the macrophages from MCG treated wounds. Furthermore, analyses of wound tissues 7 days post wounding showed up-regulation of transforming growth factor-β, vascular endothelial growth factor, von Willebrand's factor, and collagen type I expression in MCG-treated ischemic wounds. At 21 days post wounding, MCG-treated ischemic wounds displayed higher abundance of proliferating endothelial cells that formed mature vascular structures and increased blood flow to the wound. Fibroblast count was markedly higher in MCG-treated ischemic wound-edge tissue. In addition, MCG-treated wound-edge tissues displayed higher abundance of mature collagen with increased collagen type I : III deposition. Taken together, MCG helped mount a more robust inflammatory response that resolved in a timely manner, followed by an enhanced proliferative phase, angiogenic outcome, and postwound tissue remodeling. Findings of the current study warrant clinical testing of MCG in a setting of ischemic chronic wounds. © 2014 by the Wound

Oral manifestations of lupus.

2018-02-01

Mucosal involvement is commonly seen in patients with lupus; however, oral examination is often forgotten. Squamous cell carcinoma arising within oral lupoid plaques has been described, emphasizing the importance of identifying and treating oral lupus. We undertook a retrospective single-centre study looking at oral findings in patients attending our multidisciplinary lupus clinic between January 2015 and April 2016. A total of 42 patients were included. The majority of patients were female (88%) and had a diagnosis of discoid lupus erythematosus (62%). Half of the patients had positive oral findings, 26% had no oral examination documented, and 24% had documented normal oral examinations. Our findings suggest that oral pathology is common in this cohort of patients. Regular oral examination is warranted to identify oral lupus and provide treatment. Associated diseases such as Sjogren's syndrome may also be identified. Patients should be encouraged to see their general dental practitioners on a regular basis for mucosal review. Any persistent ulcer that fails to respond to treatment or hard lump needs urgent histopathological evaluation to exclude malignant transformation to squamous cell carcinoma.

Clinical diagnosis of oral erosive lichen planus by direct oral microscopy

Drogoszewska, Barbara; Polcyn, Adam; Michcik, Adam

2014-01-01

Introduction Direct oral microscopy is a novel, non-invasive diagnostic technique that aids clinical examination of the oral cavity. The basic principles of this method derive from colposcopy and dermoscopy. The principle is to reveal precancerous lesions of oral mucosae in their subclinical phase in order to begin their treatment as early as possible and prevent malignant transformation. Oral lichen planus (OLP) is an autoimmune, inflammatory, chronic disease affecting oral mucous membranes. Buccal mucosae are most often affected. Aim To describe the in vivo picture of erosive OLP in direct oral microscopy in terms of the pattern and density of subepithelial blood vessels, surface texture, color, transparency and borders of the lesions. The study also demonstrates the utility of the method in the selection of the most appropriate biopsy site. Material and methods A total of 30 patients with erosive OLP were examined. Clinical examination of the oral cavity with the naked eye was performed, followed by direct oral microscopy. The most appropriate biopsy sites based on both examinations were chosen for every individual and biopsies were taken for histopathological evaluation. Results Biopsies obtained based on direct oral microscopy revealed dysplasia in 16 patients (53.3%). Biopsies obtained based on clinical examination with the naked eye revealed dysplasia in 3 cases (10%). Conclusions Direct oral microscopy makes it possible to obtain a repeated picture of erosive OLP and constitutes an alternative to the clinical examination with the naked eye in election of the most appropriate biopsy site. Thus, introduction of the most accurate and early therapy is possible. PMID:25254007

PubMed

Decamps-Mini, D; Pelofi, J; Treisser, A

2015-06-01

The scandal of the Mediator® case led the legislature to take measures in order to regulate off-label drugs prescriptions. Indeed the law issued in December 29th, 2011 on strengthening the safety of drugs and all derivative health products came to pave the way for an "over-cautious" practice of medicine in line with the precautionary principle erected as a constitutional principle. The supervision of off-label prescribing has had a direct impact on the exercise of the medical profession and has resurrected the issues related to the freedom of prescription, the obligation to provide information to patients and in general their whole responsibility. It is important to mention that the prescribing act is part of the freedom and the strict prerogative of those skilled in the art: the physician in this case. The off-label prescription is commonly accepted in certain specialties, such as anesthesia and intensive care, oncology or pediatrics where it is even subject of a memorandum of use because of concerns regarding the availability of forms adapted to children. However, the physician must ensure that no appropriate therapeutic alternative is available and inform the patient, fundamental principle of the right to respect for the will of the person. Off-label use of the prostaglandin-E1 analogue misoprostol in obstetrics and gynecology is a good example. In fact, this drug obtained a marketing authorization for the treatment or prevention of peptic ulcers and other stomach disorders, is commonly used off-label when inducing labour or intrauterine device insertion. These are the issues that need to be clarify and carefully assessed in order to help physicians to understand the impact of the law and the state of the jurisprudence on the exercise of their profession.

Oral function improvement programs utilizing health behavior theories are considered to be effective in preventing the need for long-term social care. In the present study, an oral function improvement program based upon health behavior theories was designed, and its utility was assessed in 102 pre-frail elderly persons (33 males, 69 females, mean age: 76.9 +/- 5.7) considered to be in potential need of long-term social care and attending a long-term care prevention class in Sayama City, Saitama Prefecture, Japan. The degree of improvement in oral functions (7 items) and oral hygienic conditions (3 items) was assessed by comparing oral health before and after participation in the program. The results showed statistically significant improvements in the following oral functions: (1) lip functions (oral diadochokinesis, measured by the regularity of the repetition of the syllable "Pa"), (2) tongue functions, (3) tongue root motor skills (oral diadochokinesis, measured by the regularity of the repetition of the syllables "Ta" and "Ka"), (4) tongue extension/retraction, (5) side-to-side tongue movement functions, (6) cheek motor skills, and (7) repetitive saliva swallowing test (RSST). The following measures of oral hygiene also showed a statistically significant improvement: (1) debris on dentures or teeth, (2) coated tongue, and (3) frequency of oral cleaning. These findings demonstrated that an improvement program informed by health behavior theories is useful in improving oral functions and oral hygiene conditions.

Candida, an opportunistic fungal pathogen, has been implicated in oral and oesophageal cancers. This study aimed to examine oral Candida carriage in 52 oral cancer patients and 104 age-, gender- and denture status-matched oral cancer-free subjects. We assessed general health, smoking and alcohol drinking habits, use of alcohol-containing mouthwash and periodontal status (community periodontal index of treatment needs). Yeasts were isolated using oral rinse technique and genetically identified via Real-Time PCR-High resolution melting curve analysis of conserved ribosomal DNA. Conditional and binary logistic regressions were used to identify explanatory variables that are risk factors for oral cancer. The frequencies of oral yeasts' presence and high oral colonization were significantly higher in oral cancer than non-oral cancer patients (p=001; p=0.033, respectively). No significant difference in the isolation profile of Candida species was found between the two groups, except C. parapsilosis was more frequent in non-oral cancer group. Differences were noticed in the incidence of C. albicans strains where significantly more C. albicans genotype-A was isolated from cancer patients and significantly more C. albicans genotype-B isolated from non-cancer patients. Multiple regression analyses showed significant association with cancer observed for alcohol drinking (OR=4.253; 95% CI=1.351, 13.386), Candida presence (OR=3.242; 95% CI=1.505, 6.984) and high oral colonization (OR=3.587; 95% CI=1.153, 11.162). These results indicate that there is a significant association between oral cancer occurrence and Candida oral colonization and that the observed genotypic diversity of C. albicans strains may play a role in oral carcinogenesis.

Lundegren, Nina

2012-01-01

The main aim of this thesis was to study the oral health and the self-perceived oral treatment need of adults in Sweden. The first step was to analyse the self-perceived oral treatment need in a random national sample of young adults (20 to 25-year-olds). This study used one patient and one dentist questionnaire. The patient questionnaire was sent to 611 young adults and the response rate was 78%. After permission from 377 of these individuals, a questionnaire was sent to their dentists and answers were received from 85% (321 dentists). How the individuals perceived their oral treatment need was used as a dependent variable in a multivariate logistic regression model. Independent variables were self-assessed socio-economic situation, general health and dental attitudes together with information from the dentists on their patient's dental status. The results showed that having a high educational level, poorer oral health compared to one's peers, and being concerned about one's oral health significantly increased the odds for a high perceived oral treatment need. In this group of young adults, 33% perceived a high oral treatment need. In order to study if the oral treatment need was the same in all adult age groups and how the perceived oral health was in an adult Swedish population, a new questionnaire was sent to a random sample of 9 690 individuals, 20 to 89-year-olds, living in Skåne, Sweden. The response rate was 63%. The results showed that a majority of the adult population in Skåne had a positive perception of their oral health, in particular the individuals in the youngest age group. Most individuals had lost few teeth and removable dentures were uncommon. One third rated their dental treatment need as high. The highest proportion of individuals with a perceived high oral treatment need was found in the age group 70-79. In order to study the perceived oral treatment need in all adult age groups, the questionnaire was further analysed. The Andersen

Nonspeech Oral Movements and Oral Motor Disorders: A Narrative Review

PubMed Central

2015-01-01

Purpose Speech and other oral functions such as swallowing have been compared and contrasted with oral behaviors variously labeled quasispeech, paraspeech, speechlike, and nonspeech, all of which overlap to some degree in neural control, muscles deployed, and movements performed. Efforts to understand the relationships among these behaviors are hindered by the lack of explicit and widely accepted definitions. This review article offers definitions and taxonomies for nonspeech oral movements and for diverse speaking tasks, both overt and covert. Method Review of the literature included searches of Medline, Google Scholar, HighWire Press, and various online sources. Search terms pertained to speech, quasispeech, paraspeech, speechlike, and nonspeech oral movements. Searches also were carried out for associated terms in oral biology, craniofacial physiology, and motor control. Results and Conclusions Nonspeech movements have a broad spectrum of clinical applications, including developmental speech and language disorders, motor speech disorders, feeding and swallowing difficulties, obstructive sleep apnea syndrome, trismus, and tardive stereotypies. The role and benefit of nonspeech oral movements are controversial in many oral motor disorders. It is argued that the clinical value of these movements can be elucidated through careful definitions and task descriptions such as those proposed in this review article. PMID:26126128

Oral health survey and oral health questionnaire for high school students in Tibet, China

PubMed Central

2014-01-01

Objectives The aim of this study is to identify the oral health status as well as oral health practices and access for care of graduating senior high school Tibetan students in Shannan prefecture of Tibet. Methods Based on standards of the 3rd Chinese National Oral Epidemiological Survey and WHO Oral Health Surveys, 1907 graduating students from three senior high schools were examined for caries, periodontitis, dental fluorosis, and oral hygiene status. The questionnaire to the students addressed oral health practices and present access to oral medical services. Results Dental caries prevalence (39.96%) and mean DMFT (0.97) were high in Tibetan students. In community periodontal indexes, the detection rate of gingivitis and dental calculus were 59.50% and 62.64%, respectively. Oral hygiene index-simplified was 0.69, with 0.36 and 0.33 in debris index-simplified and calculus index-simplified, respectively. Community dental fluorosis index was 0.29, with 8.13% in prevalence rate. The questionnaire showed students had poor oral health practices and unawareness for their needs for oral health services. It was also noted that the local area provides inadequate oral medical services. Conclusions Tibetan students had higher prevalence of dental diseases and lower awareness of oral health needs. The main reasons were geographical environment, dietary habit, students’ attitude to oral health, and lack of oral health promotion and education. Oral health education and local dentists training should be strengthened to get effective prevention of dental diseases. PMID:24884668

Melanin: the biophysiology of oral melanocytes and physiological oral pigmentation

PubMed Central

2014-01-01

The presence of melanocytes in the oral epithelium is a well-established fact, but their physiological functions are not well defined. Melanin provides protection from environmental stressors such as ultraviolet radiation and reactive oxygen species; and melanocytes function as stress-sensors having the capacity both to react to and to produce a variety of microenvironmental cytokines and growth factors, modulating immune, inflammatory and antibacterial responses. Melanocytes also act as neuroendocrine cells producing local neurotransmitters including acetylcholine, catecholamines and opioids, and hormones of the melanocortin system such as proopiomelanocortin, adrenocorticotropic hormone and α-melanocyte stimulating hormone, that participate in intracellular and in intercellular signalling pathways, thus contributing to tissue homeostasis. There is a wide range of normal variation in melanin pigmentation of the oral mucosa. In general, darker skinned persons more frequently have oral melanin pigmentation than light-skinned persons. Variations in oral physiological pigmentation are genetically determined unless associated with some underlying disease. In this article, we discuss some aspects of the biophysiology of oral melanocytes, of the functions of melanin, and of physiological oral pigmentation. PMID:24661309

Good oral health is essential for good general health and quality of life. In Portugal, there are few studies on oral-health habits and the population's perceptions of this behaviour. The main purpose of this study was to characterise the Portuguese population's self-reported oral-health status, habits and perceptions, as well as their demands regarding national oral health-care services. A randomised group of 1,395 individuals, > 15 years of age, was selected as a representative sample of the Portuguese population. Face-to-face interviews were conducted, based on a structured questionnaire with closed and semi-closed questions. The data were submitted for statistical analysis using SPSS. A sample of 1,102 individuals answered the questionnaire. The great majority of the sample (97.6%) brushed their teeth daily, 70.3% had lost permanent teeth and 6.4% were edentulous. The loss of permanent teeth was statistically associated with poor oral-hygiene habits (P < 0.01). Moreover, 50.1% of the participants had experienced difficulty eating and/or drinking, 18% had felt ashamed of the appearance of their teeth and 69.3% had experienced toothache or gingival pain. A reduction in visits to a dentist in the previous 12 months was identified mainly for people from a lower social class (31.2%) and older people (29.4%). Evidence suggests that oral diseases might be more prevalent in Portuguese adults than the European average. Efforts should be made to promote good oral-hygiene habits among older people and people from lower social classes. © 2016 FDI World Dental Federation.

Mast cells are granule containing secretory cells present in oral mucosal and connective tissue environment. Oral lichen planus and oral lichenoid lesions are commonly occurring oral diseases and have some similarity clinically and histologically. Both are characterized by an extensive sub epithelial infiltrate of T cells, together with mast cells, eosinophils and blood capillaries. In this study mast cell and eosinophil densities along with number of blood capillaries were studied to find out if they could aid in histopathological distinction between oral lichen planus and lichenoid mucositis. To enumerate mast cells and compare the status of Mast Cells (Intact or Degranulated) in Lichen planus, Lichenoid mucositis and normal buccal mucosa in tissue sections stained with Toluidine Blue, and also to enumerate Eosinophils and blood capillaries in tissue sections stained with H and E. The study group included 30 cases each of oral lichen planus and oral lichenoid mucositis. 10 cases of clinically normal oral buccal mucosa formed the control group. All the sections were stained with Toluidine blue and H and E separately. Histopathological analysis was done using binocular light microscope equipped with square ocular grid to standardize the field of evaluation. The result of the study showed. · Significant increase in number of mast cells in oral lichen planus and oral lichenoid mucositis compared to normal buccal mucosa. · Significant increase of intact mast cells suepithelially within the inflammatory cell infiltrate in oral lichen planus compared to oral lichenoid mucositis. · Significant increase of degranulated mast cells in oral lichenoid mucositis to oral lichen planus, and increase in number of eosinophil densities in oral lichenoid mucositis compared to oral lichen planus. · Significant increase in number of capillaries in oral lichenoid mucositis compared to oral lichen planus.

High-risk human papillomaviruses (HR-HPV) are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investigate the epidemiology of human papillomavirus infections of the oral mucosa without pathology. A cross-sectional study was performed; samples from 390 women seeking prenatal care, Pap smears, family planning or gynecological diseases were studied. Oral cells were collected by direct swab sampling. Information regarding sociodemographic status, sexual behavior, infectious diseases, contraceptive history and tobacco and alcohol consumption were obtained through direct interviews. HPV and genotypes were detected by type-specific polymerase chain reaction. Our results revealed that 14% of the women studied had an oral HPV infection. Women ≤ 20 years of age had the highest HPV prevalence (24.5%). In total, seven genotypes were identified, including the high-risk genotypes 16, 18, 58 and 59 and the low-risk genotypes 6, 81 and 13, the latter of which is a type exclusive to oral mucosa. Sexual behavior was not associated with the presence of genital HPV types in the oral mucosa. Genital HPV types were present in the oral mucosa of women without associated clinical manifestations; however, sexual behavior was not associated with infection, and therefore others routes of transmission should be explored.

To examine the relationship between oral health literacy and oral health by adapting a valid oral health literacy instrument. A random sample of 715 students from 9 institutes was included in the study. Oral health literacy (OHL) was assessed by making the students pronounce a list of 40 words from REALD-99. Oral health status (OHL) was assessed using a modified WHO (1997) proforma. A stepwise logistic regression analysis was performed to assess the impact of independent factors on oral health literacy. The response rate was 97.9%; 15 students refused to participate, leaving 700 participants in the final sample. The mean age of the participants was 20.35±1.66 years. A statistically significant difference was observed in OHL according to the clinical parameters. Caries prevalence was higher among subjects with low OHL with a mean DMFT score of 2.69±1.53, compared with high-OHL students having a mean DMFT of 0.22±0.4. Similarly, oral hygiene status was poor among subjects with low OHL (1.53±0.6). Community periodontal index (CPI) scores were lower (1.06±0.8) in subjects with high OHL than in those with low literacy (CPI: 1.6±0.6). The present study revealed a negative correlation between oral health literacy and clinical parameters measured, that is, higher oral health literacy was associated with better oral health.

The aim of this study was to compare the effectiveness of oral health counseling sessions with traditional oral hygiene education in orthodontic patients with fixed appliances. randomised control trial with experimental and control group. A group of 99 adolescents with fixed orthodontic appliances were randomly assigned to oral health counseling (experimental) or traditional health education (control) group. Subjects in the control group received verbal instructions and a demonstration of the modified Bass brushing technique on a model. The experimental group also received the verbal information with demonstration on the model and in addition a personalised 40-minutes counseling session on oral hygiene. Plaque Index (PI) and gingivitis (G) were recorded before, 1 and 6 months after the counseling session/traditional education. Oral health counseling and traditional education improved the oral hygiene of orthodontic patients. PI values were significantly lower after 6 months compared to the baseline in both groups, but the prevalence of gingival inflammation remained significantly lower only in the experimental group. Oral health counseling increased plaque removal efficacy and control of gingival inflammation. The efficiency of counseling and traditional education was similar. Counseling is a promising approach that warrants further attention in a variety of dental contexts.

Screening for oral cancer.

Oral cancer is considered as a serious health problem resulting in high morbidity and mortality. Early detection and prevention play a key role in controlling the burden of oral cancer worldwide. The five-year survival rate of oral cancer still remains low and delayed diagnosis is considered as one of the major reasons. This increases the demand for oral screening. Currently, screening of oral cancer is largely based on visual examination. Various evidence strongly suggest the validity of visual inspection in reducing mortality in patients at risk for oral cancer. Simple visual examination is accompanied with adjunctive techniques for subjective interpretation of dysplastic changes. These include toluidine blue staining, brush biopsy, chemiluminescence and tissue autofluorescence. This review highlights the efficacy of various diagnostic methods in screening of oral cancer. © 2016 Old City Publishing, Inc.

Various distresses appear in the terminal stage of cancer. Oral problems including dry mouth, stomatitis and candidiasis are one of the important problems which should be resolved. The purpose of this study was to investigate oral problems in this stage and improvement of dry mouth by oral care. The study subjects were consecutive terminally ill cancer patients admitted over the past 2 years. Patients were divided based on the status of oral food intake into good oral food intake group (≥30%) and poor oral food intake group. The following 3 items were retrospectively investigated: 1) The incidences of these oral problems, 2) Severity of dry mouth and complication with other oral problems, 3) Improvement of dry mouth using standard oral care by nursing staff and specialist oral care including dentists as needed. There were 115 and 158 patients in good and poor oral intake groups, respectively. 1) The incidences of dry mouth, stomatitis, and candidiasis were significantly higher in poor oral intake group ( p < 0.001). 2) Severe cases of dry mouth (Grade-2&3) were noted in 20.0% and 64.8% in good and poor oral intake groups, respectively ( p < 0.0001). Candidiasis complication rate was significantly higher in poor oral intake group ( p = 0.0002). 3) The rate of dry mouth improvement by oral care was 100% in Grade-1, 86% in Grade-2 and 81% in Grade-3. Oral problems occur in many of terminally ill cancer patients. Accurate diagnosis of oral problems and corresponding appropriate interventions are important for improving quality of end-of-life care.

Oral health is affected by its resident microorganisms. Three prominent oral disorders are dental caries, gingivitis and periodontitis, with the oral microbiota playing a key role in the initiation/progression of all three. Understanding the microbiota and the diseases they may cause is critical to the development of new therapeutics. This review is focused on probiotics for the prevention and/or treatment of oral diseases. This review describes the oral ecosystem and its correlation with oral health/disease. The pathogenesis and current prevention/treatment strategies of periodontal diseases (PD) and dental caries (DC) are depicted. An introduction of probiotics is followed by an analysis of their role in PD and DC, and their potential role(s) in oral health. Finally, a discussion ensues on the future research directions and limitations of probiotics for oral health. An effective oral probiotic formulation should contribute to the prevention/treatment of microbial diseases of the oral cavity. Understanding the oral microbiota's role in oral disease is important for the development of a therapeutic to prevent/treat dental diseases. However, investigations into clinical efficacy, delivery/dose optimization, mechanism(s) of action and other related parameters are yet to be fully explored. Keeping this in mind, investigations into oral probiotic therapies are proving promising.

Oral candidosis in relation to oral immunity.

PubMed

Feller, L; Khammissa, R A G; Chandran, R; Altini, M; Lemmer, J

2014-09-01

Symptomatic oral infection with Candida albicans is characterized by invasion of the oral epithelium by virulent hyphae that cause tissue damage releasing the inflammatory mediators that initiate and sustain local inflammation. Candida albicans triggers pattern-recognition receptors of keratinocytes, macrophages, monocytes and dendritic cells, stimulating the production of IL-1β, IL-6 and IL-23. These cytokines induce the differentiation of Th17 cells and the generation of IL-17- and/or IL-22-mediated antifungal protective immuno-inflammatory responses in infected mucosa. Some immune cells including NKT cells, γδ T cells and lymphoid cells that are innate to the oral mucosa have the capacity to produce large quantities of IL-17 in response to C. albicans, sufficient to mediate effective protective immunity against C. albicans. On the other hand, molecular structures of commensal C. albicans blastoconidia, although detected by pattern-recognition receptors, are avirulent, do not invade the oral epithelium, do not elicit inflammatory responses in a healthy host, but induce regulatory immune responses that maintain tissue tolerance to the commensal fungi. The type, specificity and sensitivity of the protective immune response towards C. albicans is determined by the outcome of the integrated interactions between the intracellular signalling pathways of specific combinations of activated pattern-recognition receptors (TLR2, TLR4, Dectin-1 and Dectin-2). IL-17-mediated protective immune response is essential for oral mucosal immunity to C. albicans infection. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

This study evaluated the ethinyl estradiol (EE) and levonorgestrel (LNG) pharmacokinetic profiles of AG200-15, a transdermal contraceptive delivery system, compared with a combination oral contraceptive (COC) containing EE 35 mcg and norgestimate 250 mcg. A Phase 1, open-label, single-center study in 36 healthy women was conducted over three cycles with a randomized crossover design. After a run-in cycle of 21 days on and 7 days off with AG200-15, participants were randomized to receive one of two treatments: a 21/7-day cycle of AG200-15 either followed or preceded by one cycle of the COC. This trial is registered on ClinicalTrials.gov under the identifier NCT01243580. During the third week of AG200-15 use, mean (±standard deviation) maximum serum concentration (C(max)), area under the curve(0-168 h) and steady-state concentration (C(ss48-168 h)) for EE were 51.3 ± 17.3 pg/mL, 6.26 ± 2.46 ng h/mL and 35.7 ± 14.5 pg/mL, respectively; for LNG, the corresponding values were 2400 ± 1140 pg/mL, 317 ± 159 ng h/mL and 1847 ± 930 pg/mL, respectively. The AG200-15 EE C(max) was approximately 60% lower and the EE C(ss) was 15%-20% lower than those obtained with the COC. The calculated daily dose of AG200-15 was equivalent to a 30-mcg EE COC. The most common adverse events (AEs; >10%) in the AG200-15 group were headache, nausea and application-site irritation. All drug-related AEs were mild, and no serious AEs were reported. EE and LNG daily exposure during AG200-15 treatment was within the range reported for a low-dose COC. The daily EE dose with AG 200-15 was equivalent to a 30-mcg COC and was safe and well tolerated.

Several forms of epidermolysis bullosa (EB) present oral manifestations. Blistering of the (peri)oral mucosa affects the opening of the mouth, the mobility of the tongue and lips, thereby restricting oral functions. We describe the prevalence and characteristics of oral manifestations of EB in relation to loss of oral functions in a cross-sectional study of different types of EB patients using standardized measurement techniques. Twenty-two patients were included. The mobility of the mandible, lips and tongue was measured, the mandibular function impairment questionnaire (MFIQ) was filled out and additional questions regarding hindrance of EB during oral hygiene and intelligibility of speech (being understood) were asked in structured interviews. The median age was 11.8 yrs. Mobility of the mandible, tongue and lip was restricted, oral hygiene procedures were hindered in most patients. A data comparison was made between the recessive dystrophic EB (RDEB) and junctional EB (JEB) groups. Mandibular function was impaired in both groups but more severely in the RDEB-population. Intelligibility in both groups was almost unaffected. Restrictions in mobility of the mouth, tongue and lips are frequently present in EB patients. These are most severe in the RDEB group and support the clinical relevance of optimizing symptomatic treatment.

A new type of f lux-gate vector magnetometer based on epitaxial yttrium iron garnet films has been developed and constructed for magnetocardiography (MCG) investigations. The magnetic field sensor can operate at room temperature and measure MCG signals at a distance of about 1 mm from the thoracic cage. The high sensitivity of the sensor, better than 100 fT/Hz1/2, is demonstrated by the results of MCG measurements on rats. The main MCG pattern details and R-peak on a level of 10 pT are observed without temporal averaging, which allows heart rate anomalies to be studied. The proposed magnetic sensors can be effectively used in MCG investigations.

Prostaglandins (PGs) have been shown to protect the gastrointestinal and hematopoietic cell renewal systems from some degree of radiation damage. The mechanism(s) to account for these observations are unknown. Based on preliminary evidence that PGs varied in the degree to which they afforded protection of intestinal stem cells, we studied protection by several PGs and their analogues. The most protective PGs found to date were 16,16 dm PGE2, misoprostol, a PGE1 analogues, and iloprost, a PGI2 analogue. The relative degrees of protection were 400%, 700% and 800% above control values at a dose of 13.5 137 Cs gamma radiation. Thesemore » three PGs were used for subsequent studies. Iloprost is a stable PG at room temperature and was found to be protective given orally. In addition to radioprotection of the intestinal stem cells, these Pgs increased the LD50/6, LD50/30 and animal longevity through both the gastrointestinal and hematopoietic syndromes. Misoprostol protected the gut from JANUS neutrons and increased animal longevity following neutron irradiation. Although the mechanism for PG-induced radioprotection is unknown, it appears to be different compared to the widely studied amino thiol, WR-2721. Evidence to support this contention came from data showing that all these analogues were additive to the protective effect of Wr-2721.« less

Oral cancer has been recognized as a tumor with low sensitivity to anticancer agents. However, introduction of S-1, an oral cancer agent is improving treatment outcome for patients with oral cancer. In addition, S-1, as a main drug for oral cancer treatment in Japan can be easily available for outpatients. In fact, S-1 exerts high therapeutic effects with acceptable side effects. Moreover, combined chemotherapy with S-1 shows higher efficacy than S-1 alone, and combined chemo-radiotherapy with S-1 exerts remarkable therapeutic effects. Furthermore, we should consider the combined therapy of S-1 and molecular targeting agents right now as these combinations were reportedly useful for oral cancer treatment. Here, we describe our findings related to S-1 that were obtained experimentally and clinically, and favorable therapeutic strategies with S-1 against oral cancer with bibliographic considerations.

Members of the highly diverse Miscellaneous Crenarchaeotal Group (MCG) are globally distributed in various marine and continental habitats. In this study, we applied a polyphasic approach (rRNA slot blot hybridization, quantitative PCR (qPCR) and catalyzed reporter deposition FISH) using newly developed probes and primers for the in situ detection and quantification of MCG crenarchaeota in diverse types of marine sediments and microbial mats. In general, abundance of MCG (cocci, 0.4 μm) relative to other archaea was highest (12–100%) in anoxic, low-energy environments characterized by deeper sulfate depletion and lower microbial respiration rates (P=0.06 for slot blot and P=0.05 for qPCR). When studied in high depth resolution in the White Oak River estuary and Hydrate Ridge methane seeps, changes in MCG abundance relative to total archaea and MCG phylogenetic composition did not correlate with changes in sulfate reduction or methane oxidation with depth. In addition, MCG abundance did not vary significantly (P>0.1) between seep sites (with high rates of methanotrophy) and non-seep sites (with low rates of methanotrophy). This suggests that MCG are likely not methanotrophs. MCG crenarchaeota are highly diverse and contain 17 subgroups, with a range of intragroup similarity of 82 to 94%. This high diversity and widespread distribution in subsurface sediments indicates that this group is globally important in sedimentary processes. PMID:22551871

Oral mucositis is a side effect of chemotherapy, head and neck radiotherapy, and targeted therapy, affecting over 75% of high risk patients. Ulceration can lead to severe pain and difficulty eating and drinking, which may necessitate opioid analgesics, hospitalisation and nasogastric or intravenous nutrition. These complications may lead to interruptions or alterations to cancer therapy, which may reduce survival. There is also a risk of death from sepsis if pathogens enter the ulcers of immunocompromised patients. Ulcerative oral mucositis can be costly to healthcare systems, yet there are few preventive interventions proven to be beneficial. Oral cryotherapy is a low-cost, simple intervention which is unlikely to cause side-effects. It has shown promise in clinical trials and warrants an up-to-date Cochrane review to assess and summarise the international evidence. To assess the effects of oral cryotherapy for preventing oral mucositis in patients with cancer who are receiving treatment. We searched the following databases: the Cochrane Oral Health Group Trials Register (to 17 June 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library 2015, Issue 5), MEDLINE via Ovid (1946 to 17 June 2015), EMBASE via Ovid (1980 to 17 June 2015), CANCERLIT via PubMed (1950 to 17 June 2015) and CINAHL via EBSCO (1937 to 17 June 2015). We searched the US National Institutes of Health Trials Registry, and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching databases. We included parallel-design randomised controlled trials (RCTs) assessing the effects of oral cryotherapy in patients with cancer receiving treatment. We used outcomes from a published core outcome set registered on the COMET website. Two review authors independently screened the results of electronic searches, extracted data and assessed risk of bias. We contacted study authors for information

Gerson, S J

1990-01-01

In the U.S. oral cancer accounts for 2.1% of all cancers and 1% of cancer deaths. Two to three times as many males as females are affected. Blacks have more intra-oral cancer than whites, and their incidence and mortality rates have increased in recent years. The etiologic process very likely involves several factors. The major etiologic agents are tobacco (all types) and alcoholic beverages. Herpes simplex virus, human papilloma virus, and Candida have been implicated. Host factors include poor state of dentition, nutritional aberrations, cirrhosis of liver, lichen planus, and immunologic impairmant. Cellular changes include amplification of some oncogenes, alterations in antigen expression, production of gamma-glutamyl transpeptidase, and disturbance of keratin and involucrin production. Experimentally, cancer is readily produced on the hamster cheek pouch and rat oral mucosa. Unlike oral cancer in humans, most experimental lesions are exophytic, and they rarely metastasize.

However, in certain susceptible individuals C. albicans can become pathogenic leading to the mucocutaneous infection; oral candidiasis. Murine models and in vitro monolayer cultures have generated some data on the likely virulence and host factors that contribute to oral candidiasis but these models have limitations. Recently, tissue engineered oral mucosal models have been developed to mimic the normal oral mucosa but little information is available on their true representation. In this study, we assessed the histological features of three different tissue engineered oral mucosal models compared to the normal oral mucosa and analysed both cell damage and cytokine release following infection with C. albicans. Models comprised of normal oral keratinocytes and a fibroblast-containing matrix displayed more similar immunohistological and proliferation characteristics to normal mucosa, compared to models composed of an oral carcinoma cell line. Although all models were invaded and damaged by C. albicans in a similar manner, the cytokine response was much more pronounced in models containing normal keratinocytes. These data suggest that models based on normal keratinocytes atop a fibroblast-containing connective tissue will significantly aid in dissecting the molecular pathogenesis of oral candidiasis.

Poor oral hygiene has been suggested to be a risk factor for aspiration pneumonia in the institutionalized and disabled elderly. Control of oral biofilm formation in these populations reduces the numbers of potential respiratory pathogens in the oral secretions, which in turn reduces the risk for pneumonia. Together with other preventive measures, improved oral hygiene helps to control lower respiratory infections in frail elderly hospital and nursing home patients. Copyright © 2014 Elsevier Inc.

[Drug-induced oral ulcerations].

PubMed

Madinier, I; Berry, N; Chichmanian, R M

2000-06-01

Different side effects of drugs have been described in the oral cavity, including oral ulcerations. Direct contact between drugs and oral mucosa may induce chemical burn or local hypersensitivity. Less frequently, these drug-induced oral ulcerations are part of a complex reaction with cutaneous or systemic manifestations. Sometimes, one or more oral ulcerations appear as the main side-effect of a drug, or exceptionally as solitary lesions. Solitary oral ulcerations usually appear after few weeks of treatment. In most of cases, these lesions resist to conventional treatments, with a rapid healing following the suppression of the responsible drug. This diagnosis is usually difficult, particularly with patients receiving multiple drug therapy. Besides, special attention must be paid to new drugs. Oral ulcerations following symptoms of burning mouth, metallic taste, dysgueusia or agueusia are strongly suggestive of a pharmacological origin. Most of the molecules able to induce solitary oral ulcerations are commonly prescribed in a) rheumatology: NSAI (diclofenac, flurbiprofen, indomethacin, naproxen), long-term rheumatoid arthritis therapy (azathioprine, methotrexate, penicillamine, gold compounds, tiopronin); b) cardiology: angiotensin-converting-enzyme inhibitors (captopril, enalapril), angiotensin 2-receptor antagonist (losartan), anti-angorous (nicorandil), c) psychiatry: antidepressants (fluoxetine, lithium), d) AIDS therapy (foscarnet, zalcitabine).

Magnetocardiography (MCG) is the measurement of weak magnetic fields from the heart using Superconducting QUantum Interference Devices (SQUID). Though the measurements are performed inside magnetically shielded rooms (MSR) to reduce external electromagnetic disturbances, interferences which are caused by sources inside the shielded room could not be attenuated. The work presented here reports the application of adaptive filters to denoise MCG signals. Two adaptive noise cancellation approaches namely least mean squared (LMS) algorithm and recursive least squared (RLS) algorithm are applied to denoise MCG signals and the results are compared. It is found that both the algorithms effectively remove noisy wiggles from MCG traces; significantly improving the quality of the cardiac features in MCG traces. The calculated signal-to-noise ratio (SNR) for the denoised MCG traces is found to be slightly higher in the LMS algorithm as compared to the RLS algorithm. The results encourage the use of adaptive techniques to suppress noise due to power line frequency and its harmonics which occur frequently in biomedical measurements.

Oral lichen planus (OLP) is a chronic T cell mediated disease of oral mucosa, skin, and its appendages with a prevalence of 0.5 to 2.6% worldwide. Oral lichenoid reactions (OLR) are a group of lesions with diverse aetiologies but have clinical and histological features similar to OLP, thereby posing a great challenge in differentiating both lesions. Mast cells are multifunctional immune cells that play a major role in the pathogenesis of lichen planus by release of certain chemical mediators. Increased mast cell densities with significant percentage of degranulation have been observed as a consistent finding in pathogenesis of oral lichen planus. The current study was aimed at quantifying the mast cells in histopathological sections of OLP and OLR thereby aiding a means of distinguishing these lesions. The study group involved 21 cases of oral lichen planus, 21 cases of oral lichenoid reactions, and 10 control specimens of normal buccal mucosa. All the cases were stained with Toluidine Blue and routine haematoxylin and eosin and the mast cells were quantified. The results were analyzed using the Kruskal-Wallis test and an intergroup analysis was performed using Mann-Whitney U test. The number of mast cells showed an increased value in oral lichen planus when compared to oral lichenoid reaction and thus an estimation of mast cells count could aid in distinguishing OLP from OLR histopathologically.

Mifepristone by prescription: a dream in the United States but reality in Australia.

PubMed

Grossman, Daniel; Goldstone, Philip

2015-09-01

The requirement that mifepristone be dispensed only by physicians in offices, clinics or hospitals - and not by prescription in pharmacies - has likely limited uptake by providers in the United States. However, in several other countries, provision by prescription in pharmacies is allowed, including in Australia. Mifepristone was first registered in Australia in 2012, and in 2015, a composite package including 200 mg mifepristone and four tablets of misoprostol 200 mcg was registered. Both were approved as Schedule 4 medications, which require prescribing by a physician and may be dispensed at pharmacies. As part of the registration for both products, a risk management plan was instituted that has several components. First, physicians must be certified to prescribe mifepristone. General practitioners wishing to become certified must complete online training that includes prescribing requirements and managing the medical abortion process; obstetrician-gynecologists are exempt from the online learning module. Pharmacists must also be certified in order to dispense the medication, although this does not require additional training. When a pharmacist receives a prescription for mifepristone, she or he must confirm through a secure website that the prescriber is certified. In every region of the country, there are more certified prescribers and dispensers of mifepristone than the number of facilities providing abortion care. The experience in Australia demonstrates the feasibility of mifepristone by prescription and should be a model for expanding access to early medical abortion in the United States.

2004-12-01

This paper gives general information on the location of Kenya, its demography, economy, organisation of health services, general health policy, health financing, oral health infrastructure, problems that hamper health financing and proposals on how to solve these problems. Further, a summary of health status of the Kenyan people is given based on the results of studies. The mean DMFT for the rural and urban populations is low and there is no evidence of an increase or decrease. Similarly, the prevalence of periodontitis is low (1-10%), with no increase. Ulcerative lesions are rare (0.12%). The most common birth defects are cleft lip and palate. Oral cancer is very low, accounting for 2% of all malignancies. Comparative studies have not demonstrated any dramatic change in the frequency of oral cancer for the last 25 years. Oral candidiasis is the most prevalent oral lesion amongst HIV/AIDS patients. In June 2003, Kenya formulated a National Oral Health Policy, which gives direction on how to improve the oral health status of the citizens.

Oral lichen planus to oral lichenoid lesions: Evolution or revolution

The diagnosis between different diseases may be impaired by clinical and histopathologic similarities, as observed in the oral lichen planus (OLP) and oral lichenoid lesion (OLL). Inspite of similar clinicopathological features; etiology, diagnosis and prognosis differ which mandates separation of OLL from OLP. Hence, it is essential for the oral physician and oral pathologist to be familiarized with the individual variations among clinicopathological features of OLP and OLL as well as to obtain a thorough history and perform a complete mucocutaneous examination in addition to specific diagnostic testing. The difficulties faced to establish the diagnosis between these two pathologies are widely investigated in the literature with a lack of definite conclusion. This review is an attempt to throw some light on these clinicopathologic entities with the aim to resolve the diagnostic dilemma. PMID:26980966

Nash, David A.; Nagel, Ron J.

2005-01-01

American Indian and Alaska Native (AIAN) children are disproportionately affected by oral disease compared with the general population of American children. Additionally, AIAN children have limited access to professional oral health care. The Indian Health Service (IHS) and AIAN tribal leaders face a significant problem in ensuring care for the oral health of these children. We discuss the development and deployment of a new allied oral health professional, a pediatric oral health therapist. This kind of practitioner can effectively extend the ability of dentists to provide for children not receiving care and help to confront the significant oral health disparities existing in AIAN children. Resolving oral health disparities and ensuring access to oral health care for American Indians and Alaska Natives is a moral issue—one of social justice. PMID:16006412

The skin bacterium Propionibacterium acnes has been reported to be responsible for surgical site infections (SSIs). Skin disinfection before surgery therefore is of the utmost importance in the prevention of SSIs caused by skin bacteria. We assessed the susceptibility of clinical isolates of two skin bacteria, P. acnes and Staphylococcus epidermidis, to disinfectants. The range of chlorhexidine digluconate (CHG) minimum inhibitory concentrations (MICs) for P. acnes isolates was 0.25-1 mcg/mL. Furthermore, the minimum bactericidal concentrations (MBCs) for a range of disinfectants were determined to evaluate their rapid bactericidal activity. The MBC range of CHG against the P. acnes isolates was 4,096->32,768 mcg/mL (MBC 80 16,384 mcg/mL) after one minute of exposure and 1,024-32,768 mcg/mL (MBC 80 8,192 mcg/mL) after five minutes, indicating that some strains required a CHG MBC higher than the commercial concentration of 2% (20,000 mcg/mL). In contrast, the MBCs of glutaraldehyde, sodium hypochlorite, povidone-iodine, ethanol, benzalkonium chloride, and olanexidine gluconate were all sufficiently lower than their commercial concentrations. In S. epidermidis, the MBC range of CHG was 128-1,024 mcg/mL at one minute of exposure and 4-8 mcg/mL at five minutes. Different skin bacteria have different susceptibilities to disinfectants. To prevent SSIs, the selected disinfectant agent and the disinfection time should have bactericidal activity toward all the bacteria that pose a risk of infection.

This study sought to advance understanding of the influence of psychosocial factors on oral health by examining how parental self-efficacy (with regard to acting on their child's oral health needs) and oral health knowledge relate to parental and child oral health behaviors and self-rated oral health. Parents of children in grades 0/1 and 5/6 (n = 804) and children in grades 5/6 (n = 377, mean age 11.5 ± 1.0, 53.9% female) were recruited from a stratified random sample of 11 primary (elementary) schools. Participants completed surveys capturing psychosocial factors, oral health-related knowledge, and parental attitudes about oral health. Parents also rated their own oral health status and the oral health of their child. Correlations and logistic regression analysis (adjusted for socioeconomic status, child age, and gender) examined associations between psychosocial factors and the outcomes of interest (parent and child behaviors and self-rated oral health status). Higher parental self-efficacy was associated with more frequent toothbrushing (by parent and child), and more frequent visits to a dental professional. These associations were particularly strong with regard to dental visits for children, with parents with the highest tertile for self-efficacy 4.3 times more likely to report that their child attended a dentist for a checkup at least once a year (95%CI 2.52-7.43); and 3 times more likely to report their child brushing their teeth at least twice a day (Adjusted Odds Ratio 3.04, 95%CI 1.64-5.64) compared with those parents in the lowest tertile for self-efficacy. No associations with oral health knowledge were found when examined by tertile of increasing knowledge. Oral health self-efficacy and knowledge are potentially modifiable risk factors of oral health outcomes, and these findings suggest that intervening on these factors could help foster positive dental health habits in families. © 2012 John Wiley & Sons A/S.

Although oral health care has a preventive effect against ventilator-associated pneumonia (VAP), the most effective method of oral health care in this respect remains to be established. The objective of this single-center, randomized, controlled trial was to investigate the relationship between VAP and various methods of oral health care. All patients included in the study (n=142) were on mechanical ventilation with oral intubation at the intensive care unit of the Tokyo Dental College Ichikawa General Hospital. They were divided into two groups, one receiving standard oral health care (Standard group), and the other receiving oral health care using an oral moisture gel instead of water (Gel group). After removal of the intubation tube, biofilm on cuff of the tube was stained with a disclosing agent to determine the contamination level. Factors investigated included sex, age, number of remaining teeth, intubation time, fever ≥38.5°C, VAP, cuff contamination level, and time required for one oral health care session. No VAP occurred in either group during the study period. The level of cuff contamination was significantly lower in the Gel group than the Standard group, and the time required for one session of oral health care was shorter (p<0.001). Multivariate analysis revealed use of the oral moisture gel as a factor affecting cuff contamination level. Use of an oral moisture gel decreased invasion of the pharynx by bacteria and contaminants together with biofilm formation on the intubation tube cuff. These results suggest that oral health care using an oral moisture gel is effective in preventing cuff contamination.

Background Thrombotic disorders remain a leading cause of death in the Western World. For decades, vitamin K antagonists used in the prevention of this pathology, such as warfarin or sintrom, were the only oral agents available for long-term anticoagulation, in spite of their disadvantages. Material and Methods An electronic database search was carried out on MedLine and The Cochrane Library Plus, without restrictions on the type of study nor dates, in English and Spanish. Abstracts were reviewed, and complete articles if necessary, considering all articles that included recommendations on DOACs and oral surgery. Results In recent years, the so-called “new oral anticoagulants” have been introduced in clinical practice to treat those patients whose medical conditions require long-term anticoagulant treatment, replacing traditional oral anticoagulants. Conclusions The new oral anticoagulants represent new therapeutic options, with a number of advantages such as poor interaction with food, minor drug interactions, and do not require periodic dose adjustments or routine controls. The purpose of this review is to establish an update on the new oral anticoagulants: Dabigatran, Rivarozaban, Apixaban and Edoxaban. Key words:Novel oral anticoagulants, Dabigatran, Rivaroxaban, Apixaban, Edoxaban, bleeding management, oral surgery, Anti-IIa, Anti Xa. PMID:28809374

Erosive oral lichen planus and desquamative gingivitis are uncommon but severe debilitating variants of oral lichen planus. Treatment of these presentations is difficult and challenging. A 44-year-old woman was referred to the dermatology clinic with chronic painful lichen planus-related gingivitis and buccal erosions. She has failed multiple treatments including topical clobetasol and tacrolimus, intralesional corticosteroids and several systemic and immunosuppressive agents. Following completion of three months of treatment with oral apremilast at a dose of 30 mg twice daily, significant improvement was noted in her disease activity. Oral apremilast may be a safe and effective treatment for erosive oral lichen planus.

Quantifying oral inflammatory load: oral neutrophil counts in periodontal health and disease.

Neutrophils are the primary white blood cells that are recruited to fight the initial phases of microbial infections. While healthy norms have been determined for circulating blood neutrophil counts in order to identify patients with suspected systemic infections, the levels of oral neutrophils (oPMNs) in oral health and in the presence of periodontal diseases have not been described. It is important to address this deficiency in our knowledge as neutrophils are the primary immune cell present in the crevicular fluid and oral environment and previous work has suggested that they may be good indicators of overall oral inflammation and periodontal disease severity. The objective of this study was to measure oPMN counts obtained in a standardized oral rinse from healthy patients and from those with chronic periodontal disease in order to determine if oPMN levels have clinical relevance as markers of periodontal inflammation. A parallel goal of this investigation was to introduce the concept of 'oral inflammatory load', which constitutes the inflammatory burden experienced by the body as a consequence of oral inflammatory disease. Periodontal examinations of patients with a healthy periodontium and chronic periodontal disease were performed (n = 124). Two standardized consecutive saline rinses of 30 s each were collected before patient examination and instrumentation. Neutrophils were quantified in the rinse samples and correlated with the clinical parameters and periodontal diagnosis. Average oPMN counts were determined for healthy patients and for those with mild, moderate and severe chronic periodontal diseases. A statistically significant correlation was found between oPMN counts and deep periodontal probing, sites with bleeding on probing and overall severity of periodontal disease. oPMN counts obtained through a 30-s oral rinse are a good marker of oral inflammatory load and correlate with measures of periodontal disease severity. © 2014 John Wiley & Sons A

Towards understanding oral health.

Zaura, Egija; ten Cate, Jacob M

During the last century, dental research has focused on unraveling the mechanisms behind various oral pathologies, while oral health was typically described as the mere absence of oral diseases. The term 'oral microbial homeostasis' is used to describe the capacity of the oral ecosystem to maintain microbial community stability in health. However, the oral ecosystem itself is not stable: throughout life an individual undergoes multiple physiological changes while progressing through infancy, childhood, adolescence, adulthood and old age. Recent discussions on the definition of general health have led to the proposal that health is the ability of the individual to adapt to physiological changes, a condition known as allostasis. In this paper the allostasis principle is applied to the oral ecosystem. The multidimensionality of the host factors contributing to allostasis in the oral cavity is illustrated with an example on changes occurring in puberty. The complex phenomenon of oral health and the processes that prevent the ecosystem from collapsing during allostatic changes in the entire body are far from being understood. As yet individual components (e.g. hard tissues, microbiome, saliva, host response) have been investigated, while only by consolidating these and assessing their multidimensional interactions should we be able to obtain a comprehensive understanding of the ecosystem, which in turn could serve to develop rational schemes to maintain health. Adapting such a 'system approach' comes with major practical challenges for the entire research field and will require vast resources and large-scale multidisciplinary collaborations. 2015 S.

Langerhans cells (LCs) are effective antigen-presenting cells that function as "custodians" of mucosa, modifying the immune system to pathogen entry, and tolerance to self-antigen and commensal microbes. A reduction in number of LCs in human immunodeficiency virus (HIV)-positive individuals may predispose to local mucosal infections. To quantitatively determine the number of oral mucosal LCs in HIV/acquired immunodeficiency syndrome HIV/acquired immunodeficiency syndrome (AIDS) associated oral Kaposi sarcoma (KS) with/without oral candidiasis (OC) and to define in situ interrelationships between the cells, OC, and HIV infection. Thirty-two periodic acid-Schiff. (PAS) stained histologic sections of palatal HIV/AIDS associated KS with intact oral epithelium were examined for Candida and divided into two groups: . (1) KS coinfected with Candida and. (2) KS noninfected with Candida. Sections were immunohistochemically stained with CD1a. The standard length of surface epithelium was measured and number of positively stained LCs counted per unit length. Control cases included non-Candida infected palatal mucosa overlying pleomorphic adenoma. (PA) and oral mucosa infected with Candida in otherwise healthy individuals. LC number per unit length of surface epithelium was statistically significantly greatest in uninfected PA mucosa and lowest in KS coinfected with Candida (P = 0.0001). A statistically significant difference was also noted between uninfected PA mucosa and non-Candida infected KS (P = 0.0014), in KS coinfected with Candida and non-infected KS (P = 0.0035), between OC and PA (P = 0.0001), and OC and KS coinfected with Candida (P = 0.0247). LC numbers are significantly reduced in oral tissues of HIV/AIDS infected patients by Candida infection when compared to oral tissues without.

To determine the prevalence of oral malodour in Indian children and also to assess the relationship of oral malodour with oral hygiene, gingival health, dental caries, tongue coating, mouth breathing and frequency of tooth brushing. A total number of 900 school children (7-15 years) were included in the study. Children were assessed for the oral malodour, oral hygiene, gingival health, dental caries, tongue coating, mouth breathing and frequency of tooth brushing. The prevalence of oral malodour in Davangere school children was found to be 40.9%. Oral malodour was significantly (p < 0.001) associated with age, mouth breathing, tongue coating, oral hygiene status, gingival status and tooth brushing frequency. Oral malodour was not significantly correlated with gender and caries status. The prevalence of malodour in the population studied was 40.9% and oral health status and oral malodour were associated with one another. The prevalence of oral malodour was considerably high and should not be neglected in children.

The Oral Microbiota.

PubMed

Arweiler, Nicole B; Netuschil, Lutz

2016-01-01

The oral microbiota represents an important part of the human microbiota, and includes several hundred to several thousand diverse species. It is a normal part of the oral cavity and has an important function to protect against colonization of extrinsic bacteria which could affect systemic health. On the other hand, the most common oral diseases caries, gingivitis and periodontitis are based on microorganisms. While (medical) research focused on the planktonic phase of bacteria over the last 100 years, it is nowadays generally known, that oral microorganisms are organised as biofilms. On any non-shedding surfaces of the oral cavity dental plaque starts to form, which meets all criteria for a microbial biofilm and is subject to the so-called succession. When the sensitive ecosystem turns out of balance - either by overload or weak immune system - it becomes a challenge for local or systemic health. Therefore, the most common strategy and the golden standard for the prevention of caries, gingivitis and periodontitis is the mechanical removal of this biofilms from teeth, restorations or dental prosthesis by regular toothbrushing.

To study concentrations in the gynecological organs, ceftazidime (CAZ) was given intravenously by one shot of 0.5 g to 1 patient and of 1.0 g to 10 patients who underwent simple hysterectomy because of uterine myoma. Also, clinical effect of the drug was studied in 3 cases. The levels of CAZ in sera in uterine artery and elbow vein, and tissue concentrations in various sites of the gynecological organs obtained during 50 to 425 minutes after administration were determined by the paper-disc method with P. mirabilis ATCC 21100 strain. Concentrations of CAZ at 92 minutes after administration of 1.0 g i.v. were 39.8 mcg/ml in serum of uterine artery, 47.6 mcg/ml in serum of elbow vein, 20.5 mcg/g (tissue/serum ratio 0.43) in the ovary, 18.0 mcg/g (0.38) in the fallopian tube, 16.1 mcg/g (0.34) in the endometrium, 34.5 mcg/g (0.72) in the myometrium, 30.8 mcg/g (0.65) in the uterine cervix, 36.4 mcg/g (0.76) in the portio vaginalis and then gradually decreased time-dependently. Tissue concentrations were higher than those in serum in the endometrium, uterine cervix and portio vaginalis at 147 minutes after administration. CAZ concentrations of adipose tissue between 353 and 365 minutes after injection of 1.0 g were lower than 0.8 mcg/g. The clinical responses to CAZ in intrapelvic infections were good in all cases. Slight elevation of total bilirubin, to 1.5 mg/dl, was observed in a case. In the light of these clinical findings, CAZ appears to be a potent antibiotic effective in the clinical application.

Generic and oral quality of life is affected by oral mucosal diseases

PubMed Central

2012-01-01

Background The generic and oral health-related quality of life (QoL) has provided opportunity for investigation of the interrelations among generic health, oral health, and related outcomes. The purpose of this study was to identify the generic and oral QoL in the patients with oral mucosal disease (OMD). Methods Five hundred and thirty-eight OMDs were recruited in this study. The instruments applied were Chinese version of the 36-item short form health survey (SF-36) and the short-form of Oral Health Impact Profile (OHIP-14). Results The mean score of sum OHIP-14 was significantly higher in the patients with OMD (10.81 ± 9.01) compared with those in the healthy subjects (HS) (6.55 ± 6.73) (p < 0.001, Mann-Whitney U test). 56.51% of the OMD patients and 12.94% of the HS reported at least one oral negative impact (p < 0.001, Chi-square test). The overall mean score of SF-36 was significantly lower in the patients with OMD (74.54 ± 12.77) compared with those in the HS (77.97 ± 12.39) (p = 0.021, t-test). Conclusions Administration of specific and generic questionnaires of QoL can provide us a detailed picture of the impact of OMDs on patients, and both generic and oral QoL were impaired in the patients with OMD.

Heightened interest in oral health has lead to an increase in patients complaining of xerostomia, which is associated with various oral mucosal disorders. In this study, we investigated the relationship between Candida species and oral mucosal disorders in patients with xerostomia. We evaluated whole salivary flow rate and presence of oral mucosal disorders in 48 patients with xerostomia and 15 healthy controls. The number of Candida species was measured as colony-forming units after propagation on selective medium. Identification of Candida at the species level was carried out by polymerase chain reaction and restriction fragment length polymorphism analysis. We then examined the relationship between Candida species and oral mucosal symptoms. Compared with controls, patients with xerostomia exhibited significantly decreased whole salivary flow rate, increased rate of oral mucosal symptoms, and higher numbers of Candida. Salivary flow rate negatively correlated with the number Candida. Among patients with oral candidiasis, Candida albicans was isolated from the tongue mucosa and Candida glabrata was isolated from the angle of the mouth. These results suggest that particular Candida species are involved in the pathogenesis of oral mucosal disorders in patients with xerostomia. © 2012 John Wiley & Sons A/S.

The human microbiome project (HMP) promoted further understanding of human oral microbes. However, research on the human oral microbiota has not made as much progress as research on the gut microbiota. Currently, the causal relationship between the oral microbiota and oral diseases remains unclear, and little is known about the link between the oral microbiota and human systemic diseases. To further understand the contribution of the oral microbiota in oral diseases and systemic diseases, a Human Oral Microbiome Database (HOMD) was established in the US. The HOMD includes 619 taxa in 13 phyla, and most of the microorganisms are from American populations. Due to individual differences in the microbiome, the HOMD does not reflect the Chinese oral microbial status. Herein, we established a new oral microbiome database-the Oral Microbiome Bank of China (OMBC, http://www.sklod.org/ombc ). Currently, the OMBC includes information on 289 bacterial strains and 720 clinical samples from the Chinese population, along with lab and clinical information. The OMBC is the first curated description of a Chinese-associated microbiome; it provides tools for use in investigating the role of the oral microbiome in health and diseases, and will give the community abundant data and strain information for future oral microbial studies.

This systematic review analyzed the strength of the literature and defined clinical practice guidelines for the use of oral cryotherapy for the prevention and/or treatment of oral mucositis caused by cancer therapy. A systematic review on relevant oral cryotherapy studies indexed prior to 31 December 2010 was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society for Oral Oncology (MASCC/ISOO) using OVID/MEDLINE, with publications selected for review based on defined inclusion and exclusion criteria. Findings from the reviewed studies were integrated into guidelines based on the overall level of evidence for each intervention. Guidelines were classified into three types: recommendation, suggestion, or no guideline possible. Twenty-two clinical studies and two meta-analyses were analyzed. Results were compared with the MASCC/ISOO guidelines published in 2007. The recommendation for the use of oral cryotherapy to prevent oral mucositis in patients receiving bolus fluorouracil (5-FU) was maintained, in agreement with the 2007 guidelines. A suggestion for use of oral cryotherapy to prevent oral mucositis in patients receiving high-dose melphalan as conditioning regimen with or without total body irradiation for HCST was revised from the 2007 guidelines. No guideline was possible for any other intervention, due to insufficient evidence. The evidence continues to support the use of oral cryotherapy for prevention of oral mucositis in patients receiving bolus 5-FU chemotherapy or high-dose melphalan. This intervention is consistent with the MASCC/ISOO guidelines published in 2007. The literature is limited by the fact that utilization of a double-blind study design is not feasible. Future studies that compare efficacy of oral cryotherapy with other mucositis agents in patients receiving chemotherapy with relatively short plasma half-lives would be useful.

The existence of extra-pineal melatonin has been observed in various tissues. No prior studies of melatonin in human oral mucosal tissue under the condition of chronic inflammation have been reported. The aim of this study was to investigate the presence of melatonin in oral mucosal tissue of patients with oral lichen planus (OLP) which was considered as a chronic inflammatory immune-mediated disease causing oral mucosal damage and ulcerations. Sections from formalin-fixed and paraffin-embedded oral mucosal tissue of OLP patients (n=30), and control subjects (n=30) were used in this study. Immunohistochemical staining was performed and the semiquantitative scoring system was used to assess the levels of arylalkylamine-N-acetyltransferase (AANAT: a rate-limiting enzyme in the biosynthesis pathway of melatonin), melatonin, and melatonin receptor 1 (MT1) in oral mucosa of OLP patients and normal oral mucosa of control subjects. AANAT, melatonin, and MT1were detected in oral mucosal tissue of OLP patients and control subjects. Immunostaining scores of AANAT, melatonin, and MT1 in oral mucosal tissue of OLP patients were significantly higher than those in control subjects (p=0.002, p<0.001, and p=0.031, respectively). Increased levels of AANAT, melatonin, and MT1 in the inflamed oral mucosal tissue of OLP patients imply that chronic inflammation may induce the local biosynthesis of melatonin via AANAT, and may enhance the action of melatonin via MT1.

In the present study, the relationship between the turbidity of mouth-rinse water and oral health conditions, including oral malodor, in patients with (n = 148) and without (n = 231) periodontitis was examined. The turbidity of 20 mL distilled water that the patients rinsed in their mouths 10 times was measured using a turbidimeter. Oral malodor was evaluated using an organoleptic test and Oral Chroma. Oral health conditions, including decayed teeth, periodontal status, oral hygiene status, proteolytic activity of the N-benzoyl-dl-arginine-2-napthilamide (BANA) test on the tongue coating, and salivary flow rate, were assessed. Turbidity showed significant correlations with oral malodor and all oral health parameters in the periodontitis group. In the non-periodontitis group, turbidity showed significant correlations with oral malodor and oral health parameters, including dental plaque, tongue coating, BANA test, and salivary flow rate. The regression analysis indicated that turbidity was significantly associated with methyl mercaptan and the BANA test in the periodontitis group, and with hydrogen sulfide, dental plaque, tongue coating, and salivary flow rate in the non-periodontitis group. The findings of the present study indicate that the turbidity of mouth-rinse water could be used as an indicator of oral health conditions, including oral malodor. © 2013 Wiley Publishing Asia Pty Ltd.

This study aims to comprehensively assess the association of subjective and objective oral health status and oral health behaviors with happiness, under consideration of demographic, socioeconomic, and general health-related factors. This study also aims to test whether subjective oral health outcomes are better predictors of happiness compared with objective oral health outcomes. The data were collected from 479 community-dwelling elders aged 65 years or over selected by a cluster sampling method. A questionnaire and an oral examination were implemented. A multiple regression method was conducted to assess associations with happiness index (HI). The mean age of the elders was 74.6 years. Mean (standard deviation, SD) HI, EuroQol-visual analog scale (EQ-VAS) and 14-item oral health impact profile (OHIP-14) index were 5.7 (SD 2.3), 59.8 (SD 21.1), and 16.3 (SD 13.1). In the final model, a significant association with HI of the OHIP-14 index (P = 0.091) among all the participants and significant associations of oral symptoms (P = 0.038), wearing a removable denture (P = 0.039), and of the oral health behavior of daily toothbrushing (P = 0.007) among poorer oral health QoL group were confirmed under consideration of other related factors. While correlations of HI to subjective measures of health, EQ-VAS and OHIP-14 score were moderate to weak, those to objective measures of health were only weak or insignificant. Oral impacts which might persistently affect one's daily life need to be considered in designing and delivering public services aimed to promote people's happiness. With oral health impacts and behaviors accounting for 10% of happiness among elders, public and community services for the elderly that support oral health and daily toothbrushing for the dentate are critical for the well-being of our elders. © 2013 John Wiley & Sons A/S.

Volatile sulfur compounds (VSCs) produced by bacteria in niches of the oral cavity play a major role in the etiology of bad breath, and can be easily detected by a portable sulfide monitor (Halimeter). To investigate the effect of an oral hygiene program on VSC levels, Halimeter readings were taken from 55 healthy dental students during a course in oral hygiene training, including instruction on brushing, flossing and professional tooth cleaning. Ten students who received no oral hygiene training served as a negative control. The oral hygiene status was measured using the papillary bleeding index (PBI). PBI and VSC values did not show significant changes during the study period of 10 weeks in the control group. In the test group, PBI values significantly decreased compared to baseline and the control, indicating that the oral hygiene program had a benefit on the oral hygiene status. The VSC values also decreased significantly during the study period compared to baseline and the control. It was concluded that in a group of dental students, a thorough oral hygiene training program was capable of reducing the oral level of VSC Halimeter readings.

Magnetocardiography (MCG) is the recording of the magnetic field (MF) generated by cardiac electrophysiological activity. Because it is a contactless method, MCG is ideal for noninvasive cardiac mapping of small experimental animals. The aim of this study was to assess age-related changes of cardiac intervals and ventricular repolarization (VR) maps in intact rats by means of MCG mapping. Twenty-four adult Wistar rats (12 male and 12 female) were studied, under anesthesia, with the same unshielded 36-channel MCG instrumentation used for clinical recordings. Two sets of measurements were obtained from each animal: 1) at 5 mo of age (297.5 +/- 21 g body wt) and 2) at 14 mo of age (516.8 +/- 180 g body wt). RR and PR intervals, QRS segment, and QTpeak, QTend, JTpeak, JTend, and Tpeak-end were measured from MCG waveforms. MCG imaging was automatically obtained as MF maps and as inverse localization of cardiac sources with equivalent current dipole and effective magnetic dipole models. After 300 s of continuous recording were averaged, the signal-to-noise ratio was adequate for study of atrial and ventricular MF maps and for three-dimensional localization of the underlying cardiac sources. Clear-cut age-related differences in VR duration were demonstrated by significantly longer QTend, JTend, and Tpeak-end in older Wistar rats. Reproducible multisite noninvasive cardiac mapping of anesthetized rats is simpler with MCG methodology than with ECG recording. In addition, MCG mapping provides new information based on quantitative analysis of MF and equivalent sources. In this study, statistically significant age-dependent variations in VR intervals were found.

The seeds of Parkia clappertoniana Keay (Family: Fabaceae) are extensively used in food in the form of a local condiment called 'Dawadawa' in Ghana and consumed by all class of people including sensitive groups such as pregnant women and children. Also, crudely pounded preparations of P. clappertoniana seeds are used as labor inducing agent in farm animals by local farmers across northern Ghana where nomadism is the livelihood of most indigenes. Ecologically, P. clappertoniana is extensively distributed across the savannah ecological zone of many African countries where just like Ghana it enjoys ethnobotanical usage. Although, many studies have investigated some aspects of the pharmacological activity of P. clappertoniana, none of these studies focused on the reproductive system, particularly its effects on reproductive performance and toxicity. To contribute, this study assessed the effect of aqueous seed extract of P. clappertoniana (PCE) on reproductive performance and toxicity in Sprague-Dawley rats and ICR mice. After preparation of PCE, it was then tested on rodents at different gestational and developmental windows (1-7, 8-14, and 15-term gestational days) to assess the following: mating behavior, implantation rate, maternal and developmental toxicities. Generally, animals were randomly grouped into five and treated as follows: normal saline group (5ml/kg po), cytotec (misoprostol) group (200mg/kg po), folic acid group (5mg/kg po), and PCE groups (100, 200, and 500mg/kg po), however, these groupings were varied to suit the specific requirements of some parameters. For acute toxicity, animals were orally administered PCE (3 and 5g/kg for mice and rats respectively). PCE-treated rats showed improved mating behavior compared to control rats. PCE improved implantation rate compared to misoprostol-treated rats. On the average, PCE-treated rats delivered termed live pubs at 21 days compared to that of folic acid-treated rats at 23 days. Also, PCE-treated rats

Background To determine the prevalence and clinicopathologic features of the oral cancer patients. Material and Methods Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Results Of the 474,851 accessioned cases, 6,151 cases (1.30%) were diagnosed in the category of oral cancer. The mean age of the patients was 58.37±15.77 years. A total of 4,238 cases (68.90%) were diagnosed in males, whereas 1911 cases (31.07%) were diagnosed in females. The male-to-female ratio was 2.22:1. The sites of predilection for oral cancer were tongue, labial/buccal mucosa, gingiva, palate, and alveolar mucosa, respectively. The three most common oral cancer in the descending order of frequency were squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Conclusions Although the prevalence of oral cancer is not high compared to other entities, oral cancer pose significant mortality and morbidity in the patients, especially when discovered late in the course of the disease. This study highlights some anatomical locations where oral cancers are frequently encountered. As a result, clinicians should pay attention to not only teeth, but oral mucosa especially in the high prevalence area as well since early detection of precancerous lesions or cancers in the early stage increase the chance of patient being cured and greatly reduce the mortality and morbidity. This study also shows some differences between pediatric and elderly oral cancer patients as well as

Ethnicity and oral cancer.

PubMed

Scully, C; Bedi, R

2000-09-01

Oral squamous-cell carcinoma, the main type of oral cancer, is among the ten most common cancers in the world. The aims of this paper were first, to consider whether there was evidence of marked ethnic variations in the incidence, management, and survival of oral cancer, and then, to review possible explanations for these variations. Evidence from the literature suggests that there is marked, inter-country variation in both the incidence and mortality from oral cancer. There is also growing evidence of intracountry ethnic differences, mostly reported in the UK and USA. These variations among ethnic groups have been attributed mainly to specific risk factors, such as alcohol and tobacco (smoking and smokeless), but dietary factors and the existence of genetic predispositions may also play a part. Variations in access to care services are also an apparent factor. The extent of ethnic differences in oral cancer is masked by the scarcity of information available. Where such data are accessible, there are clear disparities in both incidence and mortality of oral cancer between ethnic groups.

Background Up to 70% of patients receiving hematopoietic stem cell transplant develop oral mucositis as a side effect of high-dose melphalan conditioning chemotherapy. Oral cryotherapy has been documented to be potentially effective in reducing oral mucositis. The aim of this study was to examine the effectiveness of the cryotherapy protocol implemented within the hematopoietic stem cell transplant program. Methods A retrospective chart review was conducted of adult multiple myeloma patients who received high-dose melphalan conditioning therapy for autologous hematopoietic stem cell transplant. Primary endpoints were incidence and severity of oral mucositis. Secondary endpoints included duration of oral mucositis, duration of hospital stay, parenteral narcotics use and total parenteral nutrition use. Results One hundred and forty patients were included in the study, 70 patients in both no cryotherapy and cryotherapy groups. Both oral mucositis incidence and severity were found to be significantly lower in the cryotherapy group. Fifty (71.4%) experienced mucositis post cryotherapy compared to 67 (95.7%) in the no cryotherapy group (p < 0.001). The median oral mucositis severity, assessed using the WHO oral toxicity scale from grade 0-4, experienced in the no group was 2.5 vs. 2 in the cryotherapy group (p = 0.03). Oral mucositis duration and use of parenteral narcotics were also significantly reduced. Duration of hospital stay and use of parenteral nutrition were similar between the two groups. Conclusion The cryotherapy protocol resulted in a significantly lower incidence and severity of oral mucositis. These results provide evidence for the continued use of oral cryotherapy, an inexpensive and generally well-tolerated practice.

To report a case of reversible chorea in a woman with myxedema coma. We describe the clinical course, imaging findings, and laboratory test results of a patient who initially presented with myxedema coma and then developed reversible chorea upon treatment. A 33-year-old woman with a known history of primary hypothyroidism presented with a 3-week history of lethargy, progressing to a precipitous decline in consciousness that required intubation. Physical examination revealed concurrent hypothermia and bradycardia. Laboratory investigations demonstrated a thyrotropin concentration greater than 100 mIU/L, a free triiodothyronine concentration of 1.9 pg/mL, and a free thyroxine concentration of 0.24 ng/dL, but no other metabolic abnormalities. She was treated with intravenous levothyroxine therapy on the first 2 days of hospital admission (200 mcg and 250 mcg, respectively). On day 2, she was obeying commands and she was extubated. She began exhibiting choreiform movements. Thyroid function test results revealed a normal free thyroxine concentration (1.10 ng/dL), but an elevated thyrotropin concentration (40.98 mIU/L) and a low free triiodothyronine concentration (1.9 pg/mL). Findings from computed tomography and magnetic resonance imaging of her brain and analysis of cerebrospinal fluid were normal. Her regimen was transitioned to oral levothyroxine, 88 mcg daily, and by day 4, her choreiform movements ceased. Neurologic manifestations of hypothyroidism include psychomotor slowing, memory deficits, and dementia, with myxedema coma at the extreme of this spectrum. Although chorea is a rare manifestation of hyperthyroidism, this is the first report of a patient with acquired, reversible choreiform movement disorder while still being severely hypothyroid and treated with levothyroxine.

Background Recent studies suggest that placenta may harbour a unique microbiome that may have origin in maternal oral microbiome. Although the major physiological and hormonal adjustments observed in pregnant women lead to biochemical and microbiological modifications of the oral environment, very few studies evaluated the changes suffered by the oral microbiota throughout pregnancy. So, the aim of our study was to evaluate oral yeast colonization throughout pregnancy and to compare it with non-pregnant women. Material and Methods The oral yeast colonization was assessed in saliva of 30 pregnant and non-pregnant women longitudinally over a 6-months period. Demographic information was collected, a non-invasive intra-oral examination was performed and saliva flow and pH were determined. Results Pregnant and non-pregnant groups were similar regarding age and level of education. Saliva flow rate did not differ, but saliva pH was lower in pregnant than in non-pregnant women. Oral yeast prevalence was higher in pregnant than in non-pregnant women, either in the first or in the third trimester, but did not attain statistical significance. In individuals colonized with yeast, the total yeast quantification (Log10CFU/mL) increase from the 1st to the 3rd trimester in pregnant women, but not in non-pregnant women. Conclusions Pregnancy may favour oral yeast growth that may be associated with an acidic oral environment. Key words:Oral yeast, fungi, pregnancy, saliva pH. PMID:28160578

Prosthodontic rehabilitation helps to improve the oral health-related quality of life (OHRQOL). The Liverpool Oral Rehabilitation Questionnaire (LORQ) and Oral Health Impact Profile (OHIP) are specific tools that measure OHRQOL. The primary objective of this study was to assess the impact of oral rehabilitation on patients' OHRQOL following treatment for cancer of oral cavity using LORQ version 3 (LORQv3) and OHIP-14 questionnaire. Secondary objectives were to identify issues specific to oral rehabilitation, patients compliance to prosthetic rehabilitation, the effect of radiation treatment on prosthetic rehabilitation, to achieve meaningful differences over a time before & after prosthetic intervention, to carryout and document specific patient-deprived problem. Seventy-five oral cancer patients were studied. Patients were asked to rate their experience of dental problems before fabrication of prosthesis and after 1 year using LORQv3 and OHIP-14. The responses were compared on Likert scale. Patients reported with extreme problems before rehabilitation. After 1 year of prosthetic rehabilitation, there was improvement noticed in all the domain of LORQv3 and OHIP-14. Complete compliance to the use of prosthetic appliances for 1 year study period was noted. In response to the question no. 40 (LORQv3), only 15 patients who belonged to the obturator group, brought to notice the problems which were not addressed in the LORQv3 questionnaire. The study showed that the oral cancer patients coped well and adapted to near normal oral status after prosthetic rehabilitation. This contributed to the improved overall health-related quality of life.

Maintaining women's oral health.

PubMed

McCann, A L; Bonci, L

2001-07-01

Women must adopt health-promoting strategies for both general health and the oral cavity, because the health of a woman's body and oral cavity are bidirectional. For general health-maintenance strategies, dental practitioners should actively advise women to minimize alcohol use, abstain from or cease smoking, stay physically active, and choose the right foods to nourish both the body and mind. For oral health-maintenance strategies, dental practitioners should advise women on how to prevent or control oral infections, particularly dental caries and periodontal diseases. Specifically, women need to know how to remove plaque from the teeth mechanically, use appropriate chemotherapeutic agents and dentifrices, use oral irrigation, and control halitosis. Dental practitioners also need to stress the importance of regular maintenance visits for disease prevention. Adolescent women are more prone to gingivitis and aphthous ulcers when they begin their menstrual cycles and need advice about cessation of tobacco use, mouth protection during athletic activities, cleaning orthodontic appliances, developing good dietary habits, and avoiding eating disorders. Women in early to middle adulthood may be pregnant or using oral contraceptives with concomitant changes in oral tissues. Dental practitioners need to advise them how to take care of the oral cavity during these changes and how to promote the health of their infants, including good nutrition. Older women experience the onset of menopause and increased vulnerability to osteoporosis. They may also experience xerostomia and burning mouth syndrome. Dental practitioners need to help women alleviate these symptoms and encourage them to continue good infection control and diet practices.

Current stress and poor oral health.

Psychological stress appears to contribute to poor oral health systemically in combination with other chronic diseases. Few studies directly examine this relationship. Data from a cross-sectional study of 2,412 participants between the ages of 25-64 years old living in the City of Toronto between 2009 and 2012 were used to examine the relationship between current stress and two self-rated oral health outcomes (general oral health and oral pain). Dental care utilization and access to dental insurance were examined as effect modifiers. A positive relationship between current stress and poor oral health was observed for both outcomes (oral pain coefficient 0.32, 95 % CI 0.26-0.38; general oral health coefficient 0.28, 95 % CI 0.19-0.36). Effects on oral pain were stronger for the uninsured, while effects on general oral health were stronger with decreasing socioeconomic position. Our findings suggest that individuals with greater perceived stress also report poorer oral health, and that this relationship is modified by dental insurance and socioeconomic position. These findings warrant a greater focus on the role of psychological stress in the development of oral disease, including how perceived stress contributes to health inequities in self-reported oral health status. Patients experiencing stressful lives may differentially require closer monitoring and more vigilant maintenance of their oral health, above and beyond that which is needed to achieve a state of health in the oral environment of less stressed individuals. There may be health promoting effects of addressing psychosocial concerns related to dental care - particularly for the poor and uninsured.
