    Introduction Missed miscarriages, occurring in upto 15% of all clinically recognized pregnancies are a cause of concern for the patients. Though many researchers in the past have compared the surgical and medical approaches in management of such patients, only a few have executed an appraisal of two routes of misoprostol at equal dosages in treatment of first trimester missed miscarriages. Aim To compare the efficacy of misoprostol by vaginal and oral route, for the management of first trimester missed abortion; and to recognize the utility of misoprostol for cervical dilation prior to any surgical termination of pregnancy. Materials and Methods A randomized prospective trial, comparing the efficacy of misoprostol, by vaginal and oral routes, for termination of first trimester missed abortion was conducted in the Department of Obstetrics and Gynecology, Government Multi-Specialty Hospital, Chandigarh over one year. Hundred subjects satisfying the inclusion criteria from 213 consecutive women presenting to the institute with first trimester missed abortion were hospitalized. The study participants were randomly assigned to one of the two treatment groups, using sequentially numbered envelopes, to receive 400mcg misoprostol vaginally or orally to a maximum of three doses six hours apart, and outcome documented. Patients were followed up on Day 14 and 6 weeks after discharge. Primary outcome evaluated was drug-induced complete expulsion of Products of Conception (POCs). Secondary outcomes measured were induction expulsion interval, number of doses required, classification of failures, cervical canal permeability in women requiring surgical evacuation, side effects, hemoglobin drop, duration and amount of post-abortal bleeding, time of resumption of menses, experience with side effects, patient satisfaction and acceptability to treatment. Results Both routes were highly effective (vaginal=92%, oral= 74%, p=0.032), safe and acceptable with tolerable side effects. The

    Marvelon, a monophasic oral contraceptive (OC) containing 30 mcg of ethinyl estradiol and 150 mcg of desogestrel, has been available to Malaysian women through the national family planning program since 1982. To assess the safety, effectiveness, and side effects associated with this OC, 247 women who requested the pill were enrolled in a multicenter prospective study that included follow-up after the first, third, and sixth cycles of use. 81% of participants had never used any form of contraception before Marvelon. 194 women (79%) completed the 6-month study. There were no pregnancies recorded. Although women reported a slightly increased incidence of nausea, breast tenderness, and headache in the first treatment cycle, these side effects had abated by the end of the third cycle. After six cycles, mean body weight had decreased by an average of 0.4 kg. Both systolic and diastolic blood pressure were unaffected. An unexpected finding was a decrease in the severity of acne with continuous use of Marvelon. Although both spotting and breakthrough bleeding increased slightly in the first two cycles, irregular bleeding returned to pretreatment levels by the third cycle. The length of the withdrawal bleed in the pill-free week was reduced. The incidence of irregular bleeding and other side effects was substantially lower in this sample of Malaysian women than in Asian and Caucasian Marvelon users surveyed in other studies.

    Introduction Considering maternal complications, it is preferred to induce labour after 40 weeks. Labour induction is a procedure used to stimulate uterine contractions during pregnancy before the beginning of the labour. Aim The aim of this study was to compare oral misoprostol with vaginal misoprostol for induction of labour in post-term pregnancies. Materials and Methods This double blind clinical-trial study was performed on 180 post-term pregnant women who were admitted to the labour ward of Besat Hospital Sanandaj, Iran in 2013-2014. Participants were equally divided into three groups using block randomization method. The induction was performed for the first group with 100 μg of oral misoprostol, for the second group with 50 μg of oral misoprostol, and for the third group with 25 μg of vaginal misoprostol. Vaginal examination and FHR was done before repeating each dose to determine Bishop Score. Induction time with misoprostol to the start of uterine contractions, induction time to delivery, and mode of delivery, systolic tachycardia, hyper stimulation and fetal outcomes were studied as well. Results First minute Apgar scores and medication dosage of the study groups were significantly different (p=0.0001). But labour induction, induction frequency, mode of delivery, complications, and 5 minutes Apgar score in the groups had no significant difference (p>0.05). The risk of fetal distress and neonatal hospitalization of the groups were statistically significant (p=0. 02). There was no significant difference between the three groups in terms of mean time interval from the administration of misoprostol to the start of uterine contractions (labour induction), the time interval from the start of uterine contractions to delivery and taking misoprostol to delivery. From the administration of misoprostol to start of the uterine contractions the mean difference between time intervals in the three groups were not statistically significant. Conclusion Based on our

    Background Induction of labour is a common obstetric procedure. At present, different methods are used for induction of labour in women with an unfavourable cervix. Recently, we showed that in term women with an unfavorable cervix the use of a Foley catheter in comparison with vaginal Prostaglandin E2 gel, results in a comparable vaginal delivery rate. A meta-analysis on the subject indicated lower rates of hyperstimulation, and probably as a sequel fewer cases of postpartum haemorrhage. Misoprostol (PgE1) is another type of prostaglandin frequently used for labour induction, recommended by the international federation of gynaecology and obstetrics (FIGO). Misoprostol can be administered by vaginal, rectal and oral route. There is evidence that oral administration results in less asphyxia and hyperstimulation than vaginal administration. At present, valid comparisons between oral misoprostol and Foley catheter are lacking. Therefore, we propose a randomised controlled trial comparing Foley catheter to oral misoprostol in order to assess safety and cost-effectiveness. Methods/Design We plan a multicentre, randomised, controlled, open-label clinical trial among term pregnant women with a vital singleton in cephalic presentation, unfavorable cervix, intact membranes and an indication for induction of labour. After informed consent, women will be randomly allocated by a webbased randomisation system to transcervical Foley catheter or oral misoprostol (50 mcg every 4 hours). The primary outcome will be a composite of complications of uterine hyperstimulation, i.e. post partum haemorrhage and asphyxia. Secondary outcomes are mode of delivery, maternal and neonatal morbidity, costs and women’s preference. Serious adverse events such as severe maternal or neonatal morbitity or mortality will be monitored and reported to an independent data safety monitory board. With a sample size of 1860 women we will be able to demonstrate a 5% non-inferiority of the Foley catheter as

    Purpose: 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. Methods and Materials: Eighty patients with cervical cancer who had been planned to undergo brachytherapy at Dr. Luetfi Kirdar 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 {mu}g 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. Results: 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). Conclusion: Administration of misoprostol 400 {mu}g orally for cervical ripening before tandem application facilitates the procedure, increases patient tolerability and comfort, and may decrease complication rates.

    The objective of this prospective randomized placebo-controlled study was to determine the effectiveness of 400 mug oral and 400 mug vaginal misoprostol administration for cervical priming 3 h prior to manual vacuum aspiration (MVA) under local anesthesia for voluntary termination of pregnancy before 10 weeks of gestation in comparison with placebo oral or placebo vaginal administration (n=40 in each group). Postmedication cervical dilatation was similar in the oral (mean, 6.6+/-1.5) and vaginal (mean, 7.2+/-0.8) misoprostol groups but significantly higher compared with the oral (mean, 3.4+/-0.2) and vaginal (mean, 3.6+/-1.9) placebo groups. Duration of the procedure was also significantly shorter in the misoprostol groups in comparison with their placebo counterparts. Preoperative bleeding and side effects were more common in the misoprostol groups, but none required medical intervention. Intraoperative bleeding was less in the vaginal misoprostol group compared with the placebo groups. There was no significant difference in terms of visual analogue scores during the procedure, patient satisfaction, days of postoperative bleeding and rate of postoperative complications among the groups. Cervical priming with misoprostol administered orally or vaginally 3 h before MVA for termination of pregnancy under local anesthesia facilitates the procedure by decreasing the need for cervical dilatation and by shortening its duration without improving patients' pain perception and satisfaction mainly due to side effects.

    Misoprostol is a widely used alternative of prostaglandin for labor induction. Based on previous studies, we envision that small and frequent oral dosage of misoprostol is an effective method for labor induction. To monitor the misoprostol content during labor induction, a rapid, sensitive, and selective microElution solid phase extraction (μElution SPE) combined with liquid chromatography tandem mass spectrometry (LC-MS/MS) was developed. Using μElution SPE could minimize the sample consumption and elution volume in order to maximize the sample enrichment and throughput. The misoprostol acid, a metabolite of misoprostol, was gradient separated in a Bidentate C18 column, then quantified by highly-selective reaction monitoring (H-SRM) in a total run time of 6min. The developed method was optimized and validated in human plasma, and showed linear range of 0.01-10ng/mL. The limit of detection (LOD) was 0.001ng/mL. The recovery ranged from 89.0 to 96.0%, and no significant matrix effect or carryover was observed. The precision, accuracy and stability were met with the criteria of U.S. FDA guidance. The developed method was successfully applied to evaluate misoprostol concentration during labor induction in pregnant women. The concentration-time profiles approves that hourly oral administration of misoprostol is a safe and effective method without drug accumulation for labor induction. PMID:26245361

    Objectives To compare the Foley catheter and misoprostol for induction of labor in term women with premature rupture of membranes. Study Design A randomized controlled trial was performed in three university hospitals in Finland between March 2012 and September 2014. A total of 202 term women with ruptured membranes >18 hours, singleton pregnancies in cephalic presentation, unfavorable cervix, and no prior cesarean section were enrolled. Participants were randomly allocated to induction of labor by Foley catheter or oral misoprostol in a 1:1 ratio. All women received prophylactic antibiotics. The main outcomes were cesarean section and maternal and neonatal infections. Results Labor induction by Foley catheter or misoprostol showed no difference in cesarean delivery rates (23.6 vs. 18.2%; odds ratio [OR], 1.39; 95% confidence interval [CI], 0.69-2.82; p = 0.36), maternal intrapartum infections (2.2 vs. 2%; OR, 1.12; 95% CI, 0.15-8.9; p = 1.00), postpartum infections (1.1 vs. 2.0%; OR, 0.55; 95% CI, 0.05-6.18; p = 1.00), or neonatal infections (1.1 vs. 5.1%; OR, 0.21; 95% CI, 0.24-1.87; p = 0.22). The total time from induction to delivery was similar (1,311 vs. 1,435 minutes; p = 0.31) in the two groups. Conclusions Foley catheter or misoprostol can both be used for induction of labor in women with term premature rupture of membranes. PMID:27031055

    An oral toxicity study of several pregnancy category X drugs was performed in female ICR mice. The drugs were administered orally once daily for 3 days at doses of 1, 10 and 100 μg/kg for isotretinoin; 6.7, 67 and 670 μg/kg for misoprostol; 83, 830 and 8,300 μg/kg for methotrexate; 3.3, 33 and 330 μg/kg for mifepristone; and 25, 250 and 2,500 μg/kg for levonorgestrel. During the test period, clinical signs, mortality, body weight, hematology, serum biochemistry and necropsy findings were examined. Following administration of methotrexate at 8,300 μg/kg, a number of animals exhibited decreased spontaneous activity, and one animal died. In the hematological analysis, compared with those treated with the control, the animals treated with the drugs exhibited similar significant decreases in the number of granulocytes and granulocyte differentiation, and increases in lymphocyte differentiation. In the serum biochemical analysis, animals receiving high doses of the five drugs demonstrated significant changes in uric acid, glucose, alkaline phosphatase, total bilirubin, lipase, total cholesterol and calcium. At necropsy, intestinal redness was frequently observed in animals that received the high dose of methotrexate. Uterus enlargement and ovary dropsy were also detected in the groups receiving mifepristone and levonorgestrel. Despite the short-term exposure, these drugs exhibited significant side effects, including white blood cell toxicity, in the mouse model. Category X drugs can be traded illegally via the internet for the purpose of early pregnancy termination. Thus, illegal abuse of the drugs should be further discouraged to protect mothers.

    Induction of labor is common in clinical practice. Many different medical and mechanical methods have been used, but the current gold standard is vaginal dinoprostone. Misoprostol has been used for the induction of labor since 1987. In early studies with large misoprostol doses (e.g. 200 microg) there were high rates of uterine hyperstimulation. Cochrane meta-analysis, however, shows that when used in low doses it is as effective as vaginal dinoprostone and with no excess of hyperstimulation. 25 microg vaginal misoprostol 4-hourly, 50 microg oral misoprostol 4-hourly or 20 microg oral misoprostol solution 2-hourly are all safe and effective regimens. Reports of uterine rupture in women with previous cesarean sections mean that it remains contraindicated in this group. PMID:17961564

    Misoprostol, a prostaglandin E1 analogue, is commonly administered intravaginally for cervical ripening and induction of labor. There is uncertainty regarding the correct dose because of the need to divide the tablets, and there is difficulty in removing the product when there is an adverse event. A proprietary hydrogel polymer containing a removable controlled-release reservoir dose of misoprostol is being developed for vaginal administration (misoprostol vaginal insert) to address these drawbacks while maintaining efficacy. This study investigated the pharmacokinetic profiles of these vaginal inserts and orally administered misoprostol. Twelve nonpregnant women received 100-, 200-, and 400-microg misoprostol vaginal inserts and separately received an oral dose of 200 microg of misoprostol. Values for area under the plasma concentration versus time curve, from time 0 to the last measurable concentration, were dose proportional with 481, 1026, and 2191 pg.h/mL for the 100-, 200-, and 400-microg misoprostol vaginal inserts, respectively. Maximum plasma concentrations were 33.1, 73.4, and 144 pg/mL for the 100-, 200-, and 400-microg misoprostol vaginal inserts, compared with 609 pg/mL for the 200 microg of oral misoprostol. After administration of the insert, plasma misoprostol acid levels increased gradually with time of the maximum measured plasma concentration at 5 to 9 hours. Following removal of the insert, misoprostol acid was eliminated rapidly from the systemic circulation with a mean half-life <1 hour. PMID:18071191

    In enriched canine parietal cell preparations, misoprostol, an analog of prostaglandin E1 methyl ester, was rapidly deesterified to misoprostol free acid. Under this circumstance, misoprostol and misoprostol free acid exhibited equal antisecretory potency against histamine-stimulated acid secretion and bound equally well to prostaglandin E receptors. When the deesterification of misoprostol was inhibited by paraoxon, an esterase inhibitor, the antisecretory and receptor binding activity of misoprostol was markedly reduced, with potency much less than misoprostol free acid. These results indicate that misoprostol free acid is the active biological form of misoprostol that binds to prostaglandin E receptors and mediates the antisecretory action of misoprostol.

    To evaluate the efficacy and safety of vaginal misoprostol for term labour induction. A prospective study conducted at the Department of Obstetrics and Gynecology B of hospital Charles Nicolle, Tunis, over a period of 4 months. The group of subjects, selected to represent the population of interest, were pregnant patients at term undergoing cervical ripening. Patients received 50 mcg vaginal misoprostol every 12 hours. The parameters studied were: contractile abnormalities, abnormalities of fetal heart rate (FHR), mode of delivery, delayed delivery and neonatal status. 44 patients underwent cervical ripening with misoprostol. The average term was 40 WA. Nulliparous rate was 23/44 (52%). Vaginal birth rate was 31/44 (70.4%). 84% of patients received a single dose of misoprostol. FHR abnormalities were observed in 14/44 (32%). The rates of meconium-stained amniotic fluid was 12/44 (27%). Apgar score of less than 7 at 5 minutes was found in 7/44 (16%). A case of uterine rupture occurred in a primipara after a single dose of misoprostol. Our results are disappointing due to the occurrence of 1 uterine rupture and of 1 significant neonatal morbidity. Other multicentre prospective studies will be useful to better ensure the effectiveness but primarily the safety of low-dose misoprostol for induction of labour at term. PMID:27583092

    Nonsteroidal anti-inflammatory drugs (NSAIDs) can produce adverse effects by inhibiting prostaglandin (PG) synthesis. A PGE1 analogue, misoprostol, is often utilized to alleviate NSAID-related gastrointestinal side effects. This study examined the effect of misoprostol on celecoxib renal toxicity. Additionally, the effects of these drugs on cardiovascular parameters were evaluated. Four randomized rat groups were orally gavaged for 9 days, two groups receiving vehicle and two groups receiving misoprostol (100 µg/kg) twice daily. Celecoxib (40 mg/kg) was co-administered once daily to one vehicle and one misoprostol group from days 3 to 9. Urine and blood samples were collected and blood pressure parameters were measured during the study period. Hearts and kidneys were harvested on final day. Day 2 urinary electrolyte samples revealed significant reductions in sodium excretion in misoprostol (0.12±0.05 µmol/min/100 g) and misoprostol+celecoxib groups (0.07±0.02 µmol/min/100 g). At day 3, all treatment groups showed significantly reduced sodium excretion. Potassium excretion diminished significantly in vehicle+celecoxib and misoprostol+celecoxib groups from day 3 onward. Urinary kidney injury molecule-1 levels were significantly increased in vehicle+celecoxib (0.65±0.02 vs. 0.35±0.07 ng/mL, p = 0.0002) and misoprostol+celecoxib (0.61±0.06 vs. 0.37±0.06 ng/mL, p = 0.0015) groups when compared to baseline; while plasma levels of cardiac troponin I increased significantly in vehicle+celecoxib (p = 0.0040) and misoprostol+misoprostol (p = 0.0078) groups when compared to vehicle+vehicle. Blood pressure parameters increased significantly in all misoprostol treated groups. Significant elevation in diastolic (p = 0.0071) and mean blood pressure (p = 0.0153) was noted in misoprostol+celecoxib compared to vehicle+celecoxib. All treatments produced significant tubular dilatation/necrosis compared to control. No significant myocardial changes were

  17. Misoprostol for Labour Induction after Previous Caesarean Section – Forever a “No Go”?

    Rath, W.; Tsikouras, P.

    2015-01-01

    Misoprostol in oral or vaginal form is an established method of labour induction worldwide. Its use after previous caesarean section is associated with a high rate of uterine rupture; according to international guidelines it is therefore contraindicated in this setting. However the evidence base for this recommendation comprises case reports, one randomised trial that was discontinued prematurely, and numerous low quality retrospective data analyses published between 1997 and 2004. New insights into e.g. resorption kinetics, dosage and application intervals, dose dependant uterine hyperstimulation rates, as well as increasing clinical experience with misoprostol have lead to a critical reappraisal of these “historical” studies. Accordingly the evidence supporting a ban on vaginal and particularly oral misoprostol for labour induction in the context of a scarred uterus is currently insufficient for a convincing guideline recommendation. In view of the clear advantages of misoprostol over prostaglandin E2 (cheaper, more effective) a retrospective review of registry data should be conducted to determine the incidence of uterine rupture following misoprostol and the circumstances in which it occurs. A prospective, randomised trial could then be conducted on the basis of these findings (e.g. oral misoprostol vs. vaginal prostaglandin E2); known risk factors for uterine rupture including the type of uterine scar would need to be taken into account when selecting patients for vaginal delivery. Until new data from well-designed studies are available, misoprostol will continue to be contraindicated in clinical guidelines for use in labour induction after previous caesarean section.

    The stability of misoprostol oil is significantly improved in a hydroxypropyl methylcellulose (HPMC) dispersion (1:100). In order to understand the enhanced stability of misoprostol oil in HPMC, the physical state of misoprostol oil in HPMC films was investigated using differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and transmission IR (TIR). Further, to determine the effect of polymer structure and the mobility of both water and misoprostol on misoprostol stability, the rate of misoprostol degradation was investigated in the misoprostol/HPMC dispersion (1:100) at 55 degrees C. The water sorption isotherm of the dispersion at 55 degrees C was determined, at seven different relative humidities, ranging from zero to 81%. The DSC and DMA measurements indicated that misoprostol oil, up to 29% in dry weight, is molecularly dispersed in the glassy HPMC. The TIR studies showed no evidence of complexation between misoprostol and HPMC. Stability studies of the misoprostol/HPMC (1:100) dispersion indicated that the first-order rate constants for misoprostol degradation increased in a concave-up fashion as the water content of the dispersion increased. Below two percent water content, the rate of misoprostol degradation was found to be minimal. Overall, it is suggested that misoprostol is stabilized in the dispersion by being molecularly dispersed in HPMC. Further, the glassy state of HPMC should reduce the mobility of misoprostol and water, leading to a minimal rate of degradation for misoprostol at low moisture levels. PMID:1746334

    Cervical dilatation has to be considered a fundamental step in operative hysteroscopy. Different methods are used to facilitate cervical dilatation. The aim of this review is to evaluate the efficacy of Misoprostol in cervical ripening prior to operative hysteroscopy through the evaluation of published studies. Initially designed for the treatment of peptic ulcers caused by non-steroidal anti-inflammatory drugs, misoprostol, a prostaglandin E1 analogue, is commonly used for medical abortion in the first and second trimesters, cervical priming before vacuum aspiration or dilation and curettage, induction of labor, and the prevention and treatment of postpartum hemorrhage. Misoprostol was licensed for oral administration, but a large number of clinical studies have reported that vaginal administration is more effective in cervical ripening. Misoprostol is effective in inducing an adequate cervical dilatation prior to an operative hysteroscopy. Vaginal administration could be necessary for all conditions where cervical ripening is difficult to perform. Patients given GnRH analogue therapy before hysteroscopy may benefit from the application of Misoprostol. However, its use in postmenopausal patients may not be efficacious. As far as the application of Misoprostol prior to diagnostic hysteroscopy is concerned, the number of patients that may find an advantage in the treatment is probably very small. Misoprostol has some important advantages, such as easy application, very low price, and greater acceptability by doctors and patients. PMID:21926953

With up to half of all induced labors requiring cervical ripening, prostaglandins have been utilized to increase induction success and achieve vaginal delivery. Misoprostol, a synthetic prostaglandin E1 analog has the ability to mimic the changes of spontaneous labor and has been used off label for over 30 years as a labor-induction agent. In the following article, cervical ripening and induction of labor with misoprostol will be discussed. The risks and benefits of misoprostol for ripening and induction and routes of administration will be reviewed, as well as future directions and new developments for its use. PMID:26601733

    The aim of this prospective study was to assess the efficacy of intra-cervical misoprostol in the management of early pregnancy failure. Twenty women with early pregnancy failure received intra-cervical misoprostol via an endometrial sampling cannula. The first dose was 50 μg of misoprostol dissolved in 5 ml of normal saline. The administration was repeated after 12 h if there was no vaginal bleeding or pain. Nine (45%) women received 1 dose and 11 (55%) women received 2 doses of intra-cervical misoprostol. Abortion within 24 h occurred in 16 (80%) women, and complete abortion was achieved in 14 (70%) cases. Two women with incomplete abortion were managed with 600 μg of misoprostol orally (1 case) and surgical intervention (1 case). The mean time interval between the first dose and the abortion was 10.6 ± 6.3 h. Two women did not respond within 24 h of treatment initiation, 1 woman withdrew consent after the first treatment, and 1 woman developed heavy vaginal bleeding after the first dose and underwent surgical management. Intra-cervical misoprostol is a promising method of medical treatment of early pregnancy failure. Further randomized clinical trials are needed to validate its safety and efficacy. PMID:25418083

    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 0.75 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.

    Transformer schemes matching magnetocumulative generators (MCG) with high impedance loads, like vircator, look promising for achieving long pulse duration of 1 μs. An analysis of expected parameters is made here. The necessary MCG and transformer parameters are discussed and the experimental set-up is described. The shots with the MCG simulator were carried out first. At simulator voltage 40 kV and reserved energy 12 kJ, the voltage pulse with amplitude to 600 kV and 320 ns duration is generated on a triode with a virtual cathode. Microwave radiation of 300-400 MW and 200-300 ns duration is generated within a 10 cm wavelength range.

    Background: We sought to compare the effectiveness and safety of sublingual versus vaginal misoprostol for the termination of pregnancy with a live full-term fetus. Methods: This randomized, triple-blind, placebo-controlled clinical trial was performed on 200 primiparous women with normal, singleton, full-term pregnancies candidated for the induction of labor. Sublingual and vaginal tablets containing misoprostol (25 mcg) or placebo in similar shapes were administered every 4 hours until the Bishop score reached above 8. Maternal and neonatal complications and outcomes were compared. Results: There were 100 parturient women in each group. The mean maternal age, gestational age, and Bishop score at the commencement of misoprostol had no statistical differences between the sublingual and vaginal groups. The mean time interval between misoprostol commencement and delivery was 497.10±291.49 and 511.67±08.46 minutes for the sublingual and vaginal groups, correspondingly. Twenty-two women had Cesarean deliveries in the sublingual group versus 14 in the vaginal group. Meconium-stained amniotic fluid was seen in 12 women in the sublingual group and 4 in the vaginal group (P=0.03). Late fetal heart rate deceleration was observed in 8 women in the sublingual group and 4 in the vaginal group (P=0.22). The mean neonatal birth weight, blood gas value at birth, Apgar score, and length of admission time in the neonatal intensive care unit were not different between the 2 groups. Conclusion: Sublingual and vaginal misoprostol had similar effectiveness; however, meconium-stained liquor was observed considerably more frequently with sublingual misoprostol than with vaginal misoprostol.

    We present results on the development of 87Rb atomic magnetometers for the detection of a fetal magnetocardiogram (fMCG). Operating in the spin-exchange relaxation free (SERF) regime, the magnetometers' sensitivities are reported at the 1 fT /√{ Hz } level. Environmental common-mode noise, including the field from the maternal heart, can be suppressed by operating the magnetometers in a gradiometric configuration. We report on schemes from implementing such gradiometers along with recent fMCG measurements. This work is supported by the National Institutes of Health.

    Misoprostol, a 15-deoxy-16-hydroxy-16-methyl analog of PGE1, is an effective agent for the treatment of peptic ulcer disease. Efforts to impede metabolic degradation of the alpha chain of misoprostol led to the discovery of a second clinical candidate in this series. Enisoprost, a delta 4Z derivative of misoprostol, is more potent as a gastric antisecretory agent and longer acting than misoprostol. These findings prompted further work to determine the effects that two double bonds in the alpha chain might have on the activity profile of misoprostol. The most promising structure in this series was a 1:1 mixture of 3E,5Z and 3Z,5Z dienes which was about three times more potent than misoprostol in inhibiting gastric secretion in dogs, while the separation of the diarrheogenic effect was significantly improved. Chromatographic separation of the mixture was very difficult, but small amounts of each isomer were obtained by HPLC, and preliminary antisecretory studies indicated that most of the activity resided in the 3E,5Z isomer. A stereospecific synthesis of the 3E,5Z isomer was carried out to provide sufficient quantities for complete pharmacological assessment. The 3E,5Z diene was about three times more potent than misoprostol in inhibiting gastric acid secretion in dogs and also in producing diarrhea in rats. PMID:3122273

    Low misoprostol dose (microgram range), extremely low plasma levels (pg range) of misoprostol acid, and the necessity of using a complex, time consuming, and labor intensive RIA method of analysis make it technically difficult to study the pharmacokinetic profile of misoprostol in man. The clinical relevance of the misoprostol pharmacokinetic data should be interpreted with care in view of the combined local and systemic effects of the drug. The studies presented in the present review indicate: Extensive metabolism of misoprostol occurs during and/or prior to gastrointestinal absorption. Several metabolites are formed and no unchanged drug is detected in the plasma or urine. The biologically active metabolite in the plasma is misoprostol acid (SC-30695), a de-esterified derivative of misoprostol. Absorption of misoprostol and/or misoprostol acid is extremely rapid resulting in peak plasma levels of misoprostol acid in less than 15 minutes. Absorption probably occurs in the stomach. The elimination half-life of misoprostol acid is short (less than 30 minutes). No accumulation of misoprostol acid occurs in plasma following a 400 microgram q12h dosing regimen of misoprostol.

    Improving the care of women who have undergone a spontaneous or induced abortion is an important step in reducing abortion-related morbidity and mortality. Both the International Federation of Gynecology and Obstetrics (FIGO) and the World Health Organization recommend the use of manual vacuum aspiration (MVA) and misoprostol rather than sharp curettage to treat incomplete abortion. MVA was introduced into the public healthcare service in Benin in 2006 and since 2008 misoprostol has been available in 3 large maternity hospitals. The present study opted to use an oral dose of 800 μg and not to limit to pregnancies of up to 12 weeks, but to include women with second trimester abortions. After 5 years, results show that around three-quarters of the women treated with misoprostol at 13-18 weeks of pregnancy required MVA to complete uterine evacuation and approximately one-quarter had severe bleeding, confirming that the indication of misoprostol for incomplete abortion should be limited to pregnancies of up to 12 weeks.

    The use of misoprostol (PGE 1) for induction of labor has been studied in the United States since 1993. The current medical literature contains studies of this non-FDA-approved indication for misoprostol. The data reveal that misoprostol is as effective or more effective in inducing labor as are oxytocin and prostaglandin E2 (PGE 2), with less cost. Nurses need to understand the physiology of prostaglandins and management of misoprostol in labor. Nurses often must assess the safety of mother and fetus during a misoprostol induction without a protocol based on research findings. This article presents a sample protocol. PMID:11110327

    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.

    Misoprostol, a prostaglandin E1 analogue indicated for ulcer treatment, has been widely used as an abortifacient by women in Brazil, where abortion is legal only in cases of rape or incest, or to save the woman's life. Because misoprostol is an inefficient abortifacient, many women who use it have incomplete abortions and need uterine evacuation. We reviewed the records of women admitted to the main obstetric hospital of Fortaleza, capital of Ceará state, Brazil, between January, 1990, and July, 1992, for uterine evacuation after induced abortion. The number of incomplete abortions induced by misoprostol increased substantially during the first half of 1990, and declined thereafter. Of the 593 cases in 1991, 75% were related to misoprostol, 10% to the use of other specified drugs, and 6% to unspecified drugs. For the remaining 9% the procedure used was not recorded; these included 3% in whom abortion had been induced by a clandestine abortionist. The number of uterine evacuations per month fell from 89 in August, 1990, to 62 in July, 1991, when sales of misoprostol in Ceará state were suspended. The fall continued after the sale of misoprostol ceased, to about 20 cases in December, 1991; numbers remained around this level until June, 1992, sustained by clandestine sales. The lack of access to contraception is the main reason for the large numbers of unplanned pregnancies and is a major public health issue for Brazilian women. The prohibition of abortion creates a void in which misuse of medicines is one extra complication, mainly because of the poor control of drug marketing. PMID:8098403

    The literature suggests that misoprostol can be offered to patients for off-label use as it has reasonable efficacy, risk/benefit ratio, tolerance and patient satisfaction, according to the criteria for evidence-based medicine. Both the vaginal and sublingual routes are more effective than the oral route for first-trimester cervical dilatation. Vaginal misoprostol 800μg, repeated if necessary after 24 or 48h, is a possible alternative for management after early pregnancy failure. However, misoprostol has not been demonstrated to be useful for the evacuation of an incomplete miscarriage, except for cervical dilatation before vacuum aspiration. Oral mifepristone 200mg, followed 24-48h later by vaginal, sublingual or buccal misoprostol 800μg (followed 3-4h later, if necessary, by misoprostol 400μg) is a less efficacious but less aggressive alternative to vacuum aspiration for elective or medically-indicated first-trimester terminations; this alternative becomes increasingly less effective as gestational age increases. In the second trimester, vaginal misoprostol 800-2400μg in 24h, 24-48h after at least 200mg of mifepristone, is an alternative to surgery, sulprostone and gemeprost. Data for the third trimester are sparse. For women with an unripe cervix and an unscarred uterus, vaginal misoprostol 25μg every 3-6h is an alternative to prostaglandin E2 for cervical ripening at term for a live fetus. When oxytocin is unavailable, misoprostol can be used after delivery for prevention (sublingual misoprostol 600μg) and treatment (sublingual misoprostol 800μg) of postpartum haemorrhage. The use of misoprostol to promote cervical dilatation before diagnostic hysteroscopy or surgical procedures is beneficial for premenopausal women but not for postmenopausal women. Nonetheless, in view of the side effects of misoprostol, its use as a first-line treatment is not indicated, and it should be reserved for difficult cases. Misoprostol is not useful for placing or removing

    OBJECTIVE: To determine the outcome and side effects of a new drug protocol to induce abortion. DESIGN: Case series. SETTING: An urban primary care practice. PATIENTS: One hundred consecutive patients who requested elective termination of pregnancies of less than 8 weeks' gestation. INTERVENTION: Subjects received methotrexate (50 mg/m2 body surface area, administered intramuscularly) and, 3 days afterward, misoprostol (800 micrograms, given vaginally). OUTCOME MEASURES: Number of abortions induced within 24 hours and within 10 days of misoprostol administration, number of surgical aspirations conducted because of incomplete abortion, mean amount of bleeding and pain and the number of women who, if faced with the same situation, said they would again choose a drug-induced abortion over a surgical one. RESULTS: Abortion occurred within 24 hours of misoprostol administration among 48 women and within 10 days among 69 women. In total, 89 women had an abortion without surgical aspiration. Of these women, 71 said they would choose a drug-induced abortion if faced with the choice again. CONCLUSION: Abortion induced with methotrexate and misoprostol appears to be a feasible alternative to surgical abortion and deserves further study. PMID:8548705

    Termination of pregnancies (TOP), in the second and third trimesters, require feasibility to induce labour with unfavorable cervix. Combination therapy is then usually necessary. Misoprostol use is out of marketing authorization in obstetrics but is widely used for many years in TOP in the 2nd and 3rd trimesters of pregnancy. Most randomized trials comparing misoprostol to other molecules available for TOP (gemeprost, dinoprostone, sulprostone) show that misoprostol is at least as effective with fewer side effects often especially if using adapted doses and routes of administration. Sometimes, products with a marketing authorization have been used with caution due to adverse effects more or less reported with misoprostol. There is, however, no conclusive evidence in the literature showing the superiority of a dose or route of administration of misoprostol compared to another. However, sublingual and oral seem to be preferred by patients than the vaginal route which remains the most evaluated and effective route. In summary, the use of vaginal misoprostol is the first-line treatment in medical abortion in the 2nd and third trimester, in combination with at least 200mg of mifepristone 36 to 48 hours before, at a dose of 400 μg every 4 to 6 hours. However, its use must be given with caution in cases of uterine scar, but cannot be forbidden for the sole justification of not having a marketing authorization. It will nevertheless warrant information to patients and allow a reduction at least half doses. The multi-scarred uterus still justifies a lower starting dose in the minimum effective doses (100 μg or less) as a corollary, increased induction-expulsion delay. The risk-benefit balance must be discussed with the patient. The agent without any pharmacological action solely or in combination (laminar dilapans, Foley catheter or double balloon) is particularly interesting in the case of uterine scar or maternal vascular risk but requires further evaluation by other

    Objectives: Non-invasive methods of inducing a miscarriage are now considered an effective alternative to surgical evacuation (dilatation and curettage). This study aimed to evaluate the effectiveness of misoprostol in the termination of first-trimester miscarriages. Methods: This prospective study was conducted between October 2009 and September 2010 and assessed all patients admitted to the Royal Hospital in Muscat, Oman, for the termination of first-trimester miscarriages during the study period. All patients received misoprostol and the rates of successful termination were measured. Patient satisfaction was assessed using a short questionnaire. Results: A total of 290 women were included in the study. Termination with misoprostol was successful in 61.38% of the subjects. Of the remaining subjects requiring additional surgical evacuation (n = 112), 58.93% required evacuation due to failed termination with misoprostol and 65.18% underwent early evacuation (≤24 hours since their last misoprostol dose). The majority of patients experienced no side-effects due to misoprostol (89.66%). Pain was controlled with simple analgesics in 70.00% of the subjects. A high satisfaction rate (94.83%) with the misoprostol treatment was reported. Conclusion: Misoprostol was a well-tolerated drug which reduced the rate of surgical evacuation among the study subjects. This medication can therefore be used safely in the management of incomplete miscarriages. PMID:26629383

    Postpartum hemorrhage is an important cause of maternal morbidity and mortality after delivery. Active management of postpartum hemorrhage by an uterotonic drug decreases the rate of postpartum hemorrhage. The aim of this study is to evaluate the efficacy of rectal misoprostol for prevention of postpartum hemorrhage. This double blind randomized clinical trial was performed on full term pregnant women candidate for vaginal delivery, referred to Zahedan Imam Ali Hospital during 2008-2009. They were randomly divided into two groups of rectal misoprostol and oxytocin. The women in misoprostol group received 400 μg rectal misoprostol after delivery and the women in oxytocin group received 3 IU oxytocin in 1 L ringer serum, intravenously. Rate of bleeding, need to any surgery interventions, rate of transfusion and changes in hemoglobin and hematocrite were compared between two groups. A total of 400 patients (200 cases in misoprostol group and 200 in oxytocin group) entered to the study. Rate of bleeding > 500 cc was significantly higher in oxytocin group than misoprostol group (33% vs. 19%) (p = 0.005). Also, need to excessive oxytocin for management of postpartum hemorrhage was significantly lower in misoprostol group than oxytocin group (18% vs. 30%) (p = 0.003). Decrease in hematocrite was significantly more observed in oxytocin group than misoprostol group (mean decrease of hematocrite was 1.3 ± 1.6 in misoprostol group and 1.6 ± 2.2 in oxytocin group). Two groups were similar in terms of side-effects. Rectal misoprostol as an uterotonic drug can decrease postpartum hemorrhage and also can prevent from decrease of hemoglobin as compared to oxytocin.

A daily diary of bowel habits, and the occurrence and severity of abdominal symptoms, was kept by each subject throughout the study. Statistical comparisons were made by analysis of variance. In the presence of misoprostol there was a 13% decrease in the area under the plasma concentration-time curve of indomethacin over one dosing interval on Day 1 (P less than 0.01), and at steady state there was a 24% decrease in the maximum plasma concentration (P less than 0.02). The pharmacokinetics of indomethacin were not affected by co-administration of ranitidine. Accumulation of indomethacin after repeated oral dosing was not significantly altered by the co-administration of either misoprostol or ranitidine. The frequency and severity of abdominal symptoms was significantly increased (P less than 0.01) during misoprostol dosing, compared with either ranitidine or placebo plus indomethacin. When the dosing phase (Days 1-8) was compared with the washout phase (Days 9-15) in each period, misoprostol, but not ranitidine or placebo, plus indomethacin resulted in an increase (P less than 0.001) in abdominal symptom severity, frequency of bowel motions and a decrease in faecal consistency.

    In Brazil, abortion is only permitted to save the woman's life or in cases of rape. The principal effect of legal restrictions is not to make induced abortion practice less prevalent but to force poor women to resort to abortions performed under unhygienic conditions or attempt self-induced abortion. Within this context, misoprostol, a synthetic analogue of prostaglandin E1, was introduced in the country in 1986. Purchased over the counter in pharmacies, misoprostol has became a popular abortifacient method among Brazilian women. By 1990, about 70% of women hospitalized with abortion-related diagnoses reported use of the drug. In 1991, the Ministry of Health restricted the sale of misoprostol, and in some states its use was totally banned. While the proportion of abortions induced with misoprostol has decreased, the drug continues to be sold on the black market at an inflated value. Research indicates that women have acquired more experience with the drug over time, resulting in lower doses and more effective administration. Several studies show that the rate and severity of complications are significantly less among women who used misoprostol compared with women who used invasive methods. Research also suggests that about half of the women have complete abortion with misoprostol, but seek medical care as soon as they have vaginal bleeding. The experience of Brazilian women with misoprostol is an example of how women when faced with unwanted pregnancy will resort to illegal abortion whatever the costs are to their health. PMID:10075223

    Twelve healthy volunteers took part in a randomised, double-blind, balanced, cross-over study to investigate the effect of misoprostol on the pharmacokinetics of propranolol. The subjects took propranolol 80 mg twice daily by mouth plus either misoprostol 400 micrograms twice daily or placebo by mouth for 14.5 days, followed by a 2-week washout period, followed by the alternate treatment for 14.5 days. Misoprostol had no significant effect on the t/2, Cmax or AUC of propranolol either after a single dose or at steady state. PMID:1906610

    This article puts into perspective the controversy between the association of the use of misoprostol for abortion and teratogenicity studies of the type found in a case report. The use of herbal medicinal drugs and the medical-obstetric and national and international norms governing the registration and circulation of pharmaceutical products were examined. Official documents of ANVISA, the Ministry of Health and the World Health Organization on the use of misoprostol, as well as 68 articles such as case reports published in national journals, linking abortion, misoprostol and teratogenicity were reviewed, systematically filed and analyzed using the monographic method. The legal prohibition of abortion prevents the proper prescription and use of a drug such as misoprostol that is both safe and effective. Thus, the danger for the health of women is linked not to the intrinsic characteristics of the drug, but to the moral arguments that constitute negligence and disregard for the fundamental rights of women.

    The effect of misoprostol and cimetidine on gastric cell turnover was studied. Endoscopic biopsy specimens of fundic and antral mucosa were obtained from duodenal ulcer patients before and after 4 wk of therapy with cimetidine 1.2 g/day or misoprostol 800 micrograms/day. Biopsy specimens were incubated with (/sup 3/H)thymidine. Glandular column length and number of labeled cells were determined after autoradiography. There was no significant difference in column length of antral or fundic glands before or after therapy with cimetidine and misoprostol. The number of antral and fundic labeled cells was significantly decreased after misoprostol treatment (3.6 +/- 0.3 and 4.6 +/- 0.4, mean +/- SE), as opposed to their respective number before therapy (6.9 +/- 0.5 and 8.3 +/- 0.8) (p less than 0.01). On the other hand, after treatment with cimetidine, the number of antral and fundic labeled cells was significantly higher (11.8 +/- 0.9 and 7.5 +/- 1.0, respectively) as compared with their number before therapy (5.7 +/- 0.5 and 5.6 +/- 0.6, respectively). The decreased gastric cell turnover induced by misoprostol indicates that the trophic effect of prostanoids on gastric mucosa is not due to an increase in cellular kinetics. The increased gastric cell turnover induced by cimetidine may contribute to its therapeutic effect in peptic ulcer disease.

    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.

    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.

    The uncultured miscellaneous crenarchaeotic group (MCG) archaea comprise one of the most abundant microbial groups in the Earth's subsurface environment. However, very little information is available regarding the lifestyle, physiology, and factors controlling the distribution of members of this group. We established a novel method using both cultivation and molecular techniques, including a pre-PCR propidium monoazide treatment, to investigate viable members of the MCG in vitro. Enrichment cultures prepared from estuarine sediment were provided with one of a variety of carbon substrates or cultivation conditions and incubated for 3 weeks. Compared with the samples from time zero, there was an order-of-magnitude increase in the number of MCG 16S rRNA genes in almost all cultures, indicating that MCG archaea are amenable to in vitro cultivation. None of the tested substrates or conditions significantly stimulated growth of MCG archaea more than the basal medium alone; however, glycerol (0.02%) had a significantly inhibitory effect (P < 0.05). Diversity analysis of populations resulting from four culture treatments (basal medium, addition of amino acids, H2-CO2 as the gas phase, or initial aerobic conditions) revealed that the majority of viable MCG archaea were affiliated with the MCG-8 and MCG-4 clusters. There were no significant differences in MCG diversity between these treatments, also indicating that some members of MCG-4 and MCG-8 are tolerant of initially oxic conditions. The methods outlined here will be useful for further investigation of MCG archaea and comparison of substrates and cultivation conditions that influence their growth in vitro. PMID:23934495

    OBJECTIVE To identify potential predictors for treatment success in medical management with misoprostol for early pregnancy failure. METHODS We conducted a planned secondary analysis of data from a multicenter trial that compared medical and surgical management of early pregnancy failure. Medical management consisted of misoprostol 800 μg vaginally on study day 1, with a repeat dose if indicated on day 3. Women returned on days 3 and 15, and a telephone interview was conducted on day 30. Failure was defined as suction aspiration for any reason within 30 days. Demographic, historical, and outcome variables were included in univariable analyses of success. Multivariable analyses were conducted using clinical site, gestational age, and variables for which the univariable analysis resulted in a P < .1 to determine predictors of overall treatment success and first-dose success. RESULTS Of the 491 women who received misoprostol, 485 met the criteria for this secondary analysis. Lower abdominal pain or vaginal bleeding within the last 24 hours, Rh-negative blood type, and nulliparity were predictive of overall success. However, only vaginal bleeding within the last 24 hours and parity of 0 or 1 were predictive of first-dose success. Overall success exceeds 92% in women who have localized abdominal pain within the last 24 hours, Rh-negative blood type, or the combination of vaginal bleeding in the past 24 hours and nulliparity. CONCLUSION Misoprostol treatment for early pregnancy failure is highly successful in select women, primarily those with active bleeding and nulliparity. Clinicians and patients should be aware of these differences when considering misoprostol treatment. PMID:16582130

    The Miscellaneous Crenarchaeota group (MCG) Archaea is one of the predominant archaeal groups in anoxic environments and may have significant roles in the global biogeochemical cycles. However, no isolate of MCG has been cultivated or characterized to date. In this study, we investigated the genetic organization, ecophysiological properties and evolutionary relationships of MCG archaea with other archaeal members using metagenome information and the result of gene expression experiments. A comparison of the gene organizations and similarities around the 16S rRNA genes from all available MCG fosmid and cosmid clones revealed no significant synteny among genomic fragments, demonstrating that there are large genetic variations within members of the MCG. Phylogenetic analyses of large-subunit+small-subunit rRNA, concatenated ribosomal protein genes and topoisomerases IB gene (TopoIB) all demonstrate that MCG constituted a sister lineage to the newly proposed archaeal phylum Aigarchaeota and Thaumarchaeota. Genes involved in protocatechuate degradation and chemotaxis were found in a MCG fosmid 75G8 genome fragment, suggesting that this MCG member may have a role in the degradation of aromatic compounds. Moreover, the expression of a putative 4-carboxymuconolactone decarboxylase was observed when the sediment was supplemented with protocatechuate, further supporting the hypothesis that this MCG member degrades aromatic compounds.

    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.

    Fatal cases of acute shock complicating Clostridium sordellii endometritis following medical abortion with mifepristone (also known as RU-486) used with misoprostol were reported. The pathogenesis of this unexpected complication remains enigmatic. Misoprostol is a pharmacomimetic of PGE2, an endogenous suppressor of innate immunity. Clinical C. sordellii infections were associated with intravaginal misoprostol administration, suggesting that high misoprostol concentrations within the uterus impair immune responses against C. sordellii. We modeled C. sordellii endometritis in rats to test this hypothesis. The intrauterine but not the intragastric delivery of misoprostol significantly worsened mortality from C. sordellii uterine infection, and impaired bacterial clearance in vivo. Misoprostol also reduced TNF-α production within the uterus during infection. The intrauterine injection of misoprostol did not enhance mortality from infection by the vaginal commensal bacterium Lactobacillus crispatus. In vitro, misoprostol suppressed macrophage TNF-α and chemokine generation following C. sordellii or peptidoglycan challenge, impaired leukocyte phagocytosis of C. sordellii, and inhibited uterine epithelial cell human β-defensin expression. These immunosuppressive effects of misoprostol, which were not shared by mifepristone, correlated with the activation of the Gs protein-coupled E prostanoid (EP) receptors EP2 and EP4 (macrophages) or EP4 alone (uterine epithelial cells). Our data provide a novel explanation for postabortion sepsis leading to death and also suggest that PGE2, in which production is exaggerated within the reproductive tract during pregnancy, might be an important causal determinant in the pathogenesis of more common infections of the gravid uterus.

    The authors describe the clinical findings of 38 children with congenital anomalies and misoprostol intrauterine exposure. This study included 38 cases, ascertained from case series of the Hospital of Rehabilitation of Craniofacial Anomalies from University of São Paulo, with evidence of intrauterine exposure to misoprostol in the first trimester of the pregnancy. Information about misoprostol intake and drug administration route was obtained through interviews with mothers. Clinical evaluation showed 18 individuals with facial phenotype compatible with Moebius syndrome; 11 individuals with multiple congenital anomalies; and nine individuals with nonsyndromic cleft lip and/or cleft palate. This study showed a widening of the phenotypic spectrum associated with misoprostol embryotoxicity.

    Observations of (C-12)O and (C-13)O J = 1 to 0 for MCG 06-45-001 are examined. It is argued that two features of CO emission with velocities of 1 and 10 km/s indicate that the object is similar to the Galactic molecular clouds in the immediate vicinity, and not to a spiral galaxy as suggested previously. It is considered that CO emission cannot arise from a spiral galaxy at a distance of 2-5 Mpc and that the object is unlikely to be a nearby dwarf. The feature at 10 km/s is considered to arise from a molecular cloud associated with an H II region, which produces the observed IRAS flux.

    Recently, we have developed a 5-channel high-Tc SQUID system with one signal channel intended for rat magnetocardiography (MCG) in moderately shielded or "quiet" real environment. This system is an adapted version of a human MCG system which has been improved with respect to user-friendliness and stability. A dewar with a cold-warm distance of 7 mm and a refill cycle time of up to one week is utilized. The implemented high-Tc SQUIDs are single-layer devices with grain boundary junctions fabricated at KRISS with laser ablation on 10 mm × 10 mm STO substrates. In order to cancel environmental magnetic noise, three of the five SQUIDs are arranged to build an axial software first-order or second-order gradiometer with a base line of 35 mm. The other two SQUIDs are used for balancing. To overcome previous system instabilities, we have implemented an Earth field compensation for each SQUID. For this, the SQUIDs were mounted in capsules containing integrated field compensation coils. The three Earth field components are measured with an additional triaxial fluxgate, and compensated at the SQUID locations using the low-noise current source of the SQUID readout electronics. This way, the SQUIDs can be cooled and operated in a low residual field that improves system stability and reduces low-frequency SQUID noise. It is even possible to slowly move the dewar in the Earth field (dynamic field compensation). Different noise cancellation procedures were optimized and compared employing a periodic signal source.

    The use of ammonio methacrylate copolymer (Eudrgit RS, RL) to form a sustained-release solid dispersion of Misoprostol can improve and enhance two important physical and chemical properties of Misoprostol. First, the solid dispersion matrix formed by the copolymer can protect Misoprostol from being degraded by water so that its stability is improved. Second, Misoprostol can be slowly released by diffusion from the copolymer matrix. Accelerated stability studies of Misoprostol-Eudragit solid dispersion after storing at various temperatures for different time periods were carried out. According to high performance liquid chromatography (HPLC) analyses, the stability of Misoprostol in a series of Eudragit appeared significantly improved at different ratios. The Misoprostol-Eudragit dispersion can be used in a powder form, filled in capsules, or compressed into tablets. The dissolution profiles of Misoprostol-Eudragit solid dispersion and its tablets in water, pH 1. 2, 4.5 and 6.8, dissolution media show that this stable solid dispersion is a sustained-release type.

    We want to compare the efficacy and safety of vaginal versus sublingual misoprostol for cervical ripening and induction of labor. This randomized clinical trial was performed on 140 women with medical or obstetric indications for labor induction. The patients were randomly divided into two groups: vaginal and sublingual administration of misoprostol. In first group, 25 µg misoprostol was placed in the posterior fornix of the vagina and second group received 25 µg misoprostol sublingually, every 6 hours for 24 h. Maternal and neonatal outcomes were analyzed. There was no significant difference in the demographic characteristics between two groups. The main indication for cesarean section in both groups was fetal distress, followed by absence of active labor progress. Evaluation of cesarean indication was not significantly different in two groups; including fetal distress, absence of active labor, uterine over activity and failure to progress. The maternal complication in sublingual group included residual placenta (2%), tachysystole (2%), vomiting (12%), atoni (3.3%) and abdominal pain (5.5%), although there was no significant difference between two groups. Sublingual misoprostol is as effective as vaginal misoprostol for induction of labor at term. However, sublingual misoprostol has the advantage of easy administration and may be more suitable than vaginal misoprostol. PMID:24734084

    Objective The purpose of this study was to estimate whether the efficacy of treatment with intravaginal misoprostol for first-trimester pregnancy failure is enhanced by the addition of saline solution. Study design Eighty women with embryonic/fetal death or anembryonic pregnancy were assigned randomly to receive either 800 μg of misoprostol with saline solution (group I, 41 women) or without (group II, 39 women). Treatment was repeated on day 3 if the gestational sac remained. Curettage was performed if the gestational sac remained on day 8 or as necessary during at least 30 days of follow-up. Data were analyzed with the Student t test and the χ2 or Fisher exact test. Results By the first follow-up visit, 73% (group I) and 64% (group II) of women passed the gestational sac (P = .38). By the second follow-up visit, expulsion rates were 83% and 87%, respectively (P = .59). Five subjects in each group underwent curettage. Conclusion Misoprostol is effective for the treatment of failed first-trimester pregnancy. The expulsion rate is not improved by adding saline solution. PMID:14981379

    Introduction Möbius syndrome (MS; VI and VII palsy) is a rare disease that in Brazil has a great frequency because of the use of misoprostol during pregnancy. Objective Verify if the speech and language performance of children with MS whose mothers reported use of misoprostol (Cytotec, Pfizer, Connecticut, USA) are different from the performance of children of mothers who did not report use. Methods The stomatognathic system beyond receptive and expressive language and speech was evaluated in children with MS, and their mothers were questioned whether they used misoprostol during the pregnancy. Results During the interview, 61.11% of mothers reported that they took misoprostol during the pregnancy. Most of the subjects (83.3%) whose mothers took misoprostol presented bilateral palsy beyond bad mobility of the tongue (90.9%) and speech disorders (63.6%). Conclusion The number of mothers who took misoprostol without knowing the risk for MS was great. The lack of facial expressions and speech disorders were common characteristics of the individuals with MS, whether the mothers took misoprostol during the pregnancy or not. PMID:25992099

    Dysregulated cytokine metabolism plays a critical role in the pathogenesis of many forms of liver disease, including alcoholic and non-alcoholic liver disease. In this study we examined the efficacy of Misoprostol in modulating LPS-inducible TNFα and IL-10 expression in healthy human subjects and evaluated molecular mechanisms for Misoprostol modulation of cytokines in vitro. Healthy subjects were given 14day courses of Misoprostol at doses of 100, 200, and 300μg four times a day, in random order. Baseline and LPS-inducible cytokine levels were examined ex vivo in whole blood at the beginning and the end of the study. Additionally, in vitro studies were performed using primary human PBMCs and the murine macrophage cell line, RAW 264.7, to investigate underlying mechanisms of misoprostol on cytokine production. Administration of Misoprostol reduced LPS inducible TNF production by 29%, while increasing IL-10 production by 79% in human subjects with no significant dose effect on ex vivo cytokine activity; In vitro, the effect of Misoprostol was largely mediated by increased cAMP levels and consequent changes in CRE and NFκB activity, which are critical for regulating IL-10 and TNF expression. Additionally, chromatin immunoprecipitation (ChIP) studies demonstrated that Misoprostol treatment led to changes in transcription factor and RNA Polymerase II binding, resulting in changes in mRNA levels. In summary, Misoprostol was effective at beneficially modulating TNF and IL-10 levels both in vivo and in vitro; these studies suggest a potential rationale for Misoprostol use in ALD, NASH and other liver diseases where inflammation plays an etiologic role.

    Misoprostol and mifepristone have been shown to be effective for medical abortion up to 9 weeks of gestation. When used alone, the successful complete abortion rate dropped to approximately 60%. It has been demonstrated that by adding water to misoprostol, the success rate rose to 92%. This is the first randomized study to investigate the efficacy of misoprostol and water versus misoprostol alone for first trimester medical abortion in women at misoprostol) and group 2 (misoprostol alone). Vaginal misoprostol 800 microgram was given on days 1, 3 and 5. If the woman did not require vacuum aspiration during the period up to the return of first menstruation after medical abortion, the outcome was classified as complete abortion. The incidence of side-effects and the acceptability were assessed through a standardized questionnaire during and after the abortion. The complete abortion rate appeared higher when water was added but the difference did not reach statistical significance. Gastro-intestinal side-effects were common but well tolerated in both groups. Overall, 40% of the women preferred a surgical method in the future because of the high failure rate. With an overall complete abortion rate of 85%, it is probably not a clinically acceptable method even if the addition of water can improve the results. We conclude that the addition of water onto misoprostol tablets does not improve its efficacy in first trimester medical abortion. Misoprostol alone is not recommended for medical abortion (up to 9 weeks of pregnancy) because of the high failure rate and low acceptability. PMID:10783370

    Magnetocardiography (MCG) deals with the measurement of biomagnetic fields due to electrical excitation of the heart. The solution of the inverse problem of MCG and electrocardiography (ECG) is the reconstruction and visualization of the excitation process. The calculation is performed from MCG data recorded by multichannel systems. For a maximum of information content an optimized magnetometer arrangement is determined which is not realized at present. The information content with respect to imaging of bioelectric sources is defined by the slope of the singular values, respective the signal-to-noise ratio and the dimension of the nullspace. Reconstruction errors due to modelling errors are not taken into account in this work. The nullspace describes the set of non-detectable source patterns in MCG and ECG. A conventional commercial sensor arrangement will be compared to an improved sensor composition. Recent publications show evidence that MCG contains more or different diagnostic information in cardiac arrhythmia and infarction diagnosis than electrocardiography. Therefore, first results of a general comparison of the information content of MCG and ECG are presented.

    Solving the inverse problem of electrocardiography (ECG) and magnetocardiography (MCG) is often referred to as cardiac source imaging. Spatial properties of ECG and MCG as imaging systems are, however, not well known. In this modelling study, we investigate the sensitivity and point-spread function (PSF) of ECG, MCG, and combined ECG+MCG as a function of source position and orientation, globally around the ventricles: signal topographies are modelled using a realistically-shaped volume conductor model, and the inverse problem is solved using a distributed source model and linear source estimation with minimal use of prior information. The results show that the sensitivity depends not only on the modality but also on the location and orientation of the source and that the sensitivity distribution is clearly reflected in the PSF. MCG can better characterize tangential anterior sources (with respect to the heart surface), while ECG excels with normally-oriented and posterior sources. Compared to either modality used alone, the sensitivity of combined ECG+MCG is less dependent on source orientation per source location, leading to better source estimates. Thus, for maximal sensitivity and optimal source estimation, the electric and magnetic measurements should be combined.

    The debate about whether misoprostol should be distributed to low resource communities to prevent post-partum haemorrhage (PPH), recognized as a major cause of maternal mortality, is deeply polarised. This is in spite of stakeholders having access to the same evidence about the risks and benefits of misoprostol. To understand the disagreement, we conducted a qualitative analysis of the values underpinning debates surrounding community distribution of misoprostol. We found that different moral priorities, epistemic values, and attitudes towards uncertainty were the main factors sustaining the debate. With this understanding, we present a model for ethical discourse that might overcome the current impasse. PMID:25897445

    Intravaginal misoprostol, a synthetic PGE1 analogue, has largely replaced all other techniques for pregnancy termination in II trimester, because of its successful results. Incidence of II trimester pregnancy termination has also increased in the present days, because of prenatal diagnosis of pregnancies with serious fetal abnormalities like cardiovascular and skeletal malformations. But there are serious and life threatening complications reported with the use of intravaginal misoprostol. Here we are reporting a case of complete avulsion of cervix from lower part of the uterus, with the use of intravaginal misoprostol, for II trimester termination of pregnancy. So, clinicians dealing with II trimester termination of pregnancy should be aware of such complications. PMID:22919526

    The effects of misoprostol (200 micrograms as a single dose or q.i.d. as a multiple dose) on the pharmacokinetics of indomethacin (100 mg single-dose administration or 50 mg t.i.d. multiple-dose administration) were studied in 16 healthy human volunteers under single-dose and steady-state conditions in a randomized, double-blind, placebo-controlled, balanced three-period study design. The overall absorption as shown by the values for area under the concentration curve of indomethacin was unaffected by concurrent administration of misoprostol. However, misoprostol did significantly enhance the steady-state maximum concentration of indomethacin by 32%. Thus misoprostol does not interfere with the absorption of indomethacin despite the known inhibitory effects of this protaglandin analog on acid secretion. PMID:1563211

    This prospective, randomized study compared the efficacy of intravaginal misoprostol (Cytotec) and gemeprost (Cervagem) as an abortifacient for intrauterine deaths in second trimester pregnancy. Side-effects, complications and the cost-effectiveness associated with each drug were assessed. 21 out of 25 patients (84%) in the misoprostol group aborted whereas only 17 out of 25 patients (68%) in the gemeprost group aborted within 24 hours after the initiation of therapy. In the misoprostol group, the abortion rate was influenced by the gestational age with 100% abortion rate for those > 17 weeks' gestation compared to 67% for those with a gestational age of 13-16 weeks. Side-effects were rare in either group and no major complications were reported in either group. Misoprostol was definitely more cost-effective compared to gemeprost as the mean cost of inducing an abortion using misoprostol was RM 1.08 whereas that of gemeprost was RM 105. We thus concluded that misoprostol was at least as effective as gemeprost as an abortifacient for intrauterine death in second trimester pregnancy. Moreover, it was less costly, with very few side-effects. PMID:9325520

    Nonsteroidal anti-inflammatory drugs (NSAIDs), non-selective or selective inhibitors of cyclooxygenase (COX-1 and -2), reduce pain and inflammation associated with arthritic diseases. Celecoxib, a COX-2-selective inhibitor providing decreased gastric injury relative to non-selective NSAIDs, is commonly prescribed. Misoprostol, a prostaglandin analog, supplements NSAID-inhibited prostaglandin levels. As concomitant celecoxib and misoprostol administration has been shown to intensify renal adverse effects, this article examined the influence of concomitant administration on hepatic histopathology, oxidative stress, and celecoxib concentration. On days 1 and 2, rat groups (n = 6) were gavaged twice daily (two groups with vehicle and two groups with 100 μg/kg misoprostol). From day 3 to day 9, one celecoxib dose (40 mg/kg) replaced a vehicle dose of one group and one group received celecoxib in addition to misoprostol. Livers were harvested on day 10. No hepatic abnormalities were observed denoting a lack of influence by either drug. Also no change in mean biomarker levels was detected. The changes in hepatic celecoxib concentration in the misoprostol-receiving group compared to control were not significant. Thus misoprostol does not influence hepatic celecoxib effects in terms of histopathology, oxidative stress, or celecoxib concentration level at the dosage and duration examined. PMID:26441478

    Background: Misoprostol is very effective in cervical ripening and is used for termination of pregnancy. A similar effect on the nonpregnant uterus will facilitate gynecological operations, and hence we assessed the effect of misoprostol on the nonpregnant uterus of premenopausal women. Materials and Methods: In a prospective double-blinded randomized controlled trial, 280 women were randomly allocated into two groups (12 women did not complete the intervention). Study (A) and control (B) group received 400 μg of misoprostol or 400 mg of metronidazole tablets (as a placebo) respectively in the posterior vaginal wall 6 h prior to gynecological procedures. Results: The mean cervical dilatation was significantly higher (P < 0.0001) in misoprostol compared to placebo group (4.6 ± 0.96 mm vs. 3.6 ± 0.82 mm), benefit were also observed on secondary outcome measures which were need for further dilatation, time taken for further dilatation, ease of dilatation, subjective assessment of pain by visual analog scale. Only 3.61% patients complained of intolerable pain during dilatation in the study group while in control group 48.74% complained of intolerable pain and required anesthesia. Most common side effects of misoprostol were abdominal pain and mild vaginal bleeding. Conclusion: Misoprostol was effective in cervical ripening of nonpregnant premenopausal uterus to facilitate gynecological procedures. PMID:26604599

    Background: In 2 recent decades, found drug regimen to induce abortion that are more effective than surgery. Prostaglandins especially misoprostol, oxytocin and osmotic dilators such as laminaria use for termination but the best method is unknown. Therefore we aimed to assess the comparison between the Misoprostol regimen and the highly concentrated oxytocin with laminaria regimen in second trimester of pregnancy termination. Methods: In this randomized clinical trial, 100 women with gestational age 14 to 24 week coming to hospital due to termination of pregnancy in the absence of uterine contractions and items of exclusion criteria enrolled to study and randomly assign to 2 groups and received misoprostol (group 1) or oxytocin (group 2). Data collected with use of observation, examination and demographic checklist. In group 1, in admission time and then every 6 hour patients received 200 µgr misoprostol until start the pain or vaginal bleeding or abortion in 48 hr. in group 2, patients first received laminaria in cervix with duration of 6 hr and then oxytocin 50 unit in 500 cc normal saline in 3 hr. after 1 hr rest, oxytocin dosage elevated as multiple into 2 and continue until termination or maximum dose of 300 u in 500 cc normal saline. Data entered to SPSS software version 16 and analyzed with use of descriptive methods and also Chi-square and T-test. Results: In each group enrolled 50 women that approximately no different in baseline characteristic. Number of abortion in misoprostol group was more than oxytocin group (P<0.001) and duration of abortion also was shorter than oxytocin in misoprostol group (P<0.001). Side effects in 23 (46%) women in misoprostol group were seen but no side effect seen in oxytocin group. Complementally interventions was seen in 31 women (60%) in misoprostol group versus 32 women (62%) in oxytocin group but this difference was not significant (P>0.05). Conclusion: This study demonstrated that misoprostol is effective than oxytocin

    Introduction 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. Objective 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. Methods 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. Results 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. Conclusion 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.

    The efficacy of misoprostol (a synthetic analogue of prostaglandin E1) and ranitidine in the treatment of duodenal ulcer was evaluated. Seventy-one patients with endoscopically proven duodenal ulcer were randomized in a double-blind manner in one of two groups that received two daily doses of 400 micrograms misoprostol or 150 mg ranitidine. Ulcer healing was assessed endoscopically after 4 weeks of treatment; in subjects who had not healed treatment was continued and endoscopy was repeated after another 4 weeks. The mean age, sex distribution and tobacco, alcohol and caffein consumption were similar in both groups. In the misoprostol-treated group, healing of the ulcer was observed in 74.8% of patients at 4 weeks and in 86.5% at 8 weeks; in the ranitidine group (n = 34), the healing rate was 91.2 and 100%, respectively. The differences between healing rates in the two groups were not statistically significant. In the misoprostol group (n = 37), 27% of patients experienced diarrhea; of these, two were withdrawn from the trial due to this side effect. These results, which are part of a multicenter international study, suggest that misoprostol at a daily dose of 800 micrograms is as effective as 300 mg/day ranitidine in the treatment of duodenal ulcer.

    The aim of the present study was to compare the clinical and endocrinological effects of different applications of misoprostol (MIS) and aglepristone (AGL) for the induction of abortion in bitches. For this purpose, 28 healthy pregnant bitches from different breeds, ages, body weights (Body weigt, BWs, 10-40 kg), and between Days 25 to 35 of gestation were used. Bitches were randomly assigned to four groups. In group 1 (GI, n = 7), AGL (10 mg/kg BW, s.c. on 2 consecutive days); in group 2 (GII, n = 7), AGL (as in GI), intravaginal MIS (IVag, 200 μg for bitches with ≤20 kg BW, 400 μg for bitches with >20 kg BW, daily intravaginally until completion of abortion); in group 3 (GIII, n = 7), AGL (as in GI), ICVag (as in GII), per os MIS (400 μg for bitches with ≤20 kg BW, 800 μg for bitches with >20 kg BW, daily orally, until completion of abortion); in group 4 (GIV, n = 7), AGL (as in GI), per os MIS (as GIII) were used. Clinical, vaginal, and ultrasonographic examinations were performed daily until abortion was completed. For measurement of serum progesterone, blood samples were collected in all groups immediately after the first AGL administration and every other day until completion of abortion. No statistical differences were found between groups concerning the duration until completion of abortion after treatment (nonsignificant); however, in GII, one bitch completed abortion 2 days after the start of treatment.

    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

    In order to simplify management of early pregnancy loss, our goal was to elucidate predictors of successful medical management of miscarriage with a single dose of misoprostol. In this secondary analysis of data from a multicenter randomized controlled trial, candidate biomarkers were compared between 49 women with missed abortion who succeeded in passing their pregnancy with a single dose of misoprostol and 46 women who did not pass their pregnancy with a misoprostol single dose. We computed the precision of trophoblastic protein and hormone concentrations to discriminate between women who succeed or fail single dose misoprostol management. We also included demographic factors in our analyses. We found overlap in the concentrations of the individual markers between women who succeeded and failed single-dose misoprostol. However, hCG levels ≥ 4000 mIU/mL and ADAM-12 levels ≥ 2500 pg/mL were independently associated with complete uterine expulsion after one dose of misoprostol in our population. A multivariable logistic model for success included non-Hispanic ethnicity and parity <2 in addition to hCG ≥ 4000 mIU/mL and ADAM-12 ≥ 2500 pg/mL and had an area under the receiver operating characteristic (ROC) of 0.81 (95% confidence interval: 72-90%). Categorizing women with a predicted probability of ≥ 0.65 resulted in a sensitivity of 75.0%, specificity 77.1% and positive predictive value of 81.8%. While preliminary, our data suggest that serum biomarkers, especially when combined with demographic characteristics, may be helpful in guiding patient decision-making regarding the management of early pregnancy failure (EPF). Further study is warranted. PMID:26051455

    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.

    Background Misoprostol has become a popular over the counter self-administered abortifacient in Ghana. This study aimed to compare the socio-demographic characteristics and clinical complications associated with misoprostol and non-misoprostol induced abortions among patients admitted to a tertiary public health facility in Ghana. Methods This was a cross sectional study conducted at the gynaecological ward of Komfo Anokye Teaching Hospital (KATH), over a four-month period using a structured pre-tested questionnaire. Data were analysed using Chi-square, Fisher’s exact and student t-tests. Factors associated with severe morbidity were examined using Poisson regression with robust error variance to estimate crude and adjusted relative risks (RRs) with 95% confidence intervals (CIs). P < 0.05 was considered statistically significant. Results Overall, 126 misoprostol users and 126 misoprostol non-users were recruited into the study. About 71% of the clients had self-induced abortions. Misoprostol users were more likely to be younger (p < 0.001), single (p < 0.001), nulliparous (p = 0.001), of higher educational background (p = 0.001), and unemployed (p < 0.001), than misoprostol non-users. Misoprostol users were more likely than non-users to undergo termination of pregnancy because they wanted to continue schooling (p < 0.001) or were not earning regular income to support a family (p = 0.001). Overall, 182 (72.2%) of the women (79.4% misoprostol users vs. 65.1% misoprostol non-users; p = 0.01) suffered severe morbidity. Nulliparous women (adjusted RR, 1.28; 95% CI, 1.08-1.52) and those who had induced abortion after 12 weeks’ gestation (adjusted RR, 1.36; 95% CI, 1.18-1.57) were at increased risks of experiencing severe morbidity. The association between mode of abortion induction and severe morbidity was not statistically significant (p = 0.06). Conclusion Self-induced abortions using misoprostol is a common practice among women in this study; nearly three

    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.

    Outdated second trimester abortion methods are still being used in some countries, and very few studies have compared them to currently recommended methods. To this end, we studied the efficacy and safety of vaginal misoprostol used alone for abortions in 189 women at 13-20 weeks gestation, in 2004-2006. We also retrospectively collated similar data from an historical cohort of 189 women drawn consecutively and chronologically from hospital records from 2003-2006, also at 13-20 weeks gestation, who had had abortions with a combination of extra-amniotic 0.1% ethacridine lactate solution, oxytocin and sharp curettage. At 24 hours, misoprostol was 92.6% effective in inducing abortion versus 76.2% with the ethacridine lactate regimen (OR 4.2, 95% CI 2.3-8.0). The misoprostol cohort experienced fewer complications than the ethacridine cohort (4 vs. 38 cases, OR 0.086, 95% CI 0.03-0.23). We conclude that in the absence of mifepristone, misoprostol alone is preferable to the ethacridine regimen for the termination of pregnancy in the second trimester, because it works faster, has a higher success rate in a shorter period of time, and fewer complications.

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.

    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 dosedependent 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

    The MEMS-based Micrograting (MCG) is a basic building component in many optical systems. This paper presents the fabrication technique of a custom MCG whose optical surface can be reconfigured electrostatically. The ruling is made of SiO2 and both the top and the bottom electrodes are made of Cr/Au. A robust three-mask process was designed and developed. The reduced ruling width (1 micrometers ) is not a simple miniaturization of previously reported 3 micrometers and 4 micrometers ruled microgratings. Because of mechanical integrity and fringe effects at the ruling edge during device operation, the design and fabrication of the new 1 micrometers ruled MCG require new material and process integration. To achieve self-alignment between the top electrode and the ruling, the top electrode is patterned first then the pattern is transferred to the ruling material by Reactive Ion Etch (RIE). Experiments show that the lift-off process results in a smoother top electrode than ion milling. Residual stress proves to be an important factor that influences the device performance. Because Ni is used as a hard mask for RIE, the resulting stress gradient causes the rulings to bend up. The actuation voltage is increased as a result of this increased air gap. Annealing experiments are performed to reduce the material residual stress and lower the pull-in voltage. Auger Electron Spectroscopy (AES) data shows that the adhesion layer (Cr) diffuses through the Au and gets oxidized when annealing temperature is higher than 450 degree(s)C. It was found that the optimum annealing condition is at 350 degree(s)C for 1 hour. Finally, optical tests these prototypes show that the diffraction patterns switch at about 11 V, much lower than the devices reported previously.

    This paper examines the double life of misoprostol in Brazil, where it is illegally used by women as an abortifacient and legally used in obstetric hospital wards. Based on my doctoral and post-doctoral anthropological research on contraception and abortion in Salvador, Bahia, this paper initially traces the "conversion" of misoprostol from a drug to treat ulcers to a self-administered abortifacient in Latin America, and its later conversion to aneclectic global obstetric tool. It then shows how, while reducing maternal mortality, its use as an illegal abortifacient has reinforced the double reproductive citizenship regime existing in countries with restrictive abortion laws and poor post-abortion care services, where poor women using it illegally are stigmatised, discriminated against and exposed to potentially severe health risks.

    A case of a 40-year-old man with chronic anaemia because of nonspecific ulcerating and stenosing enteropathy is presented. The diagnosis was made on the basis of capsule endoscopy, histology of resected ileum and no use of NSAIDs. He showed a clinical response to treatment with misoprostol, and therefore, he was investigated for a possible impairment in eicosanoid biosynthesis compared with healthy controls. No deficient synthesis of prostacyclin, prostaglandin E2 and thromboxane was found on examination of metabolites in blood and urine. This suggests a normal release of arachidonic acid from phospholipids. Ex-vivo cyclooxygenase (COX) assays showed normal COX-1 and COX-2 activities. The clinical response to treatment with the prostaglandin E1 analogue misoprostol suggests a defective prostaglandin E synthesis in the intestinal mucosa. PMID:22786573

    Background 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. Data and methods 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. Results 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. Conclusion 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. PMID:27536161

    Background Prostaglandin has been reported to have protective effects against liver injury. Use of this agent in clinical settings, however, is limited because of drug-related side effects. This study investigated whether misoprostol, prostaglandin E1 analogue, and OP-41483, prostaglandin I2 analogue, which have fewer adverse effects with a longer half-life, attenuate ischemic liver damage. Study Design Thirty beagle dogs underwent 2 hours of hepatic vascular exclusion using venovenous bypass. Misoprostol was administered intravenously for 30 minutes before ischemia and for 3 hours after reperfusion. OP-41483 was administered intraportally for 30 minutes before ischemia (2 μg/kg/min) and for 3 hours after reperfusion (0.5 μg/kg/min). Animals were divided into five groups: untreated control group (n = 10); high-dose misoprostol (total 100 μg/kg) group (MP-H, n = 5); middle-dose misoprostol (50 μg/kg) group (MP-M, n = 5); low-dose misoprostol (25 μg/kg) group (MP-L, n = 5); and OP-41483 group (OP, n = 5). Animal survival, hepatic tissue blood flow (HTBF), liver function, and histology were analyzed. Results Two-week animal survival rates were 30% in control, 60% in MP-H, 100% in MP-M, 80% in MP-L, and 100% in OP. The treatments with prostaglandin analogues improved HTBF, and attenuated liver enzyme release, adenine nucleotrides degradation, and histologic abnormalities. In contrast to the MP-H animals that exhibited unstable cardiovascular systems, the MP-M, MP-L, and OP animals experienced only transient hypotension. Conclusions These results indicate that misoprostol and OP-41483 prevent ischemic liver damage, although careful dose adjustment of misoprostol is required to obtain the best protection with minimal side effects.

    2015-01-01

    Background Induction of labor is a major issue in pregnancy management. Finding strategies to increase rate and decrease time to vaginal delivery is an important goal, but maternal or neonatal safety must remain the primary objective. Misoprostol is a synthetic analogue of prostaglandin used off label to ripen the cervix and induce labor. The misoprostol vaginal insert (MVI) was designed to allow a controlled-release delivery of misoprostol (from 50 to 200 μg) with a removal tape. The objective of this review was to make a critical appraisal of this device referring to the literature. Methods A literature search was performed in the PubMed and Cochrane databases using the keywords “vaginal misoprostol insert”. Results Several studies compared different doses of MVI (50, 100, 150, and 200 μg) with the 10 mg dinoprostone insert. The 100 μg MVI compared with the dinoprostone vaginal insert (DVI) showed similar efficacy and no significant differences in cesarean delivery rate. MVI 200 μg compared with DVI showed a reduced time to vaginal delivery and oxytocin need but had an increased risk of uterine hyperstimulation. The rate of hyperstimulation syndrome was two to three times more frequent with the 200 μg MVI than the 100 μg. Conclusion Current data suggest that the 100 μg MVI would provide the best balance between efficacy and safety. Further studies should be performed to evaluate this dose, especially in high-risk situations needing induction of labor. PMID:26648758

    Efforts to prosecute women for induced abortion have included allegations that misoprostol was found in body fluids. These claims, however, are questionable owing to the timing of specimen collection for accurate results, the scarcity and expense of validated assays, and the onerous lab procedures required to determine the presence of the substance. Adequate scrutiny should be applied each time such a claim is made. PMID:25220862

    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.

    A high-performance liquid chromatographic (HPLC) method utilizing ultraviolet absorbance coupled with radioisotove detection was developed for the precise and simultaneous determination of iloprost and misoprostol. This assay allows complete resolution of iloprost diastereoisomers and has a total run time of approximately twenty minutes. Samples were prepared for chromatographic analysis by extracting a mixture of tritiated drugs from rat plasma with acetonitrile. The resulting solutions were chromatographed on a reversed phase Zorbax Rx-C8 column using 0.02M potassium phosphate (pH 3.0), acetonitrile, and methanol (46:30:24, v/v) at a flow rate of 1.7 mL/min. 2-Naphthoic acid was employed as an internal standard. The correlation coefficient for varying concentrations of tritiated iloprost (12.7 Ci/mmol specific activity) from 2.18 ng/mL to 21.8 ng/mL was 0.995, and the correlation coefficient for concentrations of tritiated misoprostol (50 Ci/mmol specific activity) from 0.617 ng/mL to 6.17 ng/mL was 0.993. The high selectivity and sensitivity of this assay make it useful for the simultaneous quantitation of iloprost and misoprostol. PMID:8936581

    2015-01-01

    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.

    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

    Misoprostol, a PGE analog, is an effective radioprotector of murine intestine and hematopoietic and hair cell renewal systems. The radioprotective nature of misoprostol was extended to examine its ability to influence clonogenic cell survival and induction of oncogenic transformation in Syrian hamster embryo cells exposed to X rays in utero and assayed in vitro. Hamsters in their 12th day of pregnancy were injected subcutaneously with misoprostal, and 2 h later the pregnant hamsters were exposed to graded doses of X rays. Immediately after irradiation, hamsters were euthanized and embryonic tissue was explanted into culture dishes containing complete growth medium. After a 2-week incubation period, clongenic cell survival and morphologically transformed foci were determined. Survival of misoprostol-treated SHE cells was increased and yielded a dose reduction factor of 1.5 compared to SHE cells treated with X rays alone. In contrast, radiation-induced oncogenic transformation of misoprostol-treated cells was reduced by a factor of 20 compared to cells treated with X rays alone. These studies suggest that misoprostol not only protects normal tissues in vivo from acute radiation injury, but also protects cells, to a large extent, from injury leading to transforming events. 26 refs., 6 figs., 2 tabs.

    We present a spectral analysis of the 118 ks High Energy Transmission Gratings (HETG) observation of the X-ray bright Seyfert 1.5 galaxy MCG +8-11-11, in conjunction with 100 ks of archival Suzaku data. Fe Kα line emission is clearly detected and is likely resolved by the HETG. The data are consistent with reprocessing by a distant, neutral torus that is marginally Compton thick (N_H ˜ 10^{24}cm^{-2}) and out of the line-of-sight. We do not find compelling evidence of a relativistically-broadened Fe-K emission line and, contrary to previous results, warm absorption is not required by the data. The HETG data are consistent with the presence of a soft excess, a feature that may be missed by considering Suzaku data alone.

    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.

    We present the initial results of a program to obtain high resolution images of Seyfert galaxies with the Planetary Camera aboard the Hubble Space Telescope (HST). In this paper we discuss the images of the type 2 Seyfert NGC 5929 and the type 1.5 Seyfert MCG 8-11-11 (= UGC 3374). The images were obtained in the emission lines of (O III) lambda lambda 4959 and 5007 A and H alpha + (N II) lambda lambda 6548 and 6583 A and their adjacent continua. The high-excitation gas in the narrow line region (NLR) of NGC 5929 is resolved into individual clouds in the central 1 sec .5. Although the (O III) emission is clearly not spherically symmetric with respect to the nucleus, it does not define a distinct 'bicone' morphology, as observed by the HST in a few other Seyfert galaxies. We find no direct evidence for the reddening and/or obscuration effects characteristic of a dusty torus, which, in the context of 'unified models', is expected to obscure the active galactic nucleus (AGN) in type 2 Seyfert galaxies. The correspondence between the emission line gas and the radio morphology suggests that the structure of the NLR in NGC 5929 is governed by matter ejected from the AGN. A comparison of the recombination rate of hydrogen in the brightest emission line cloud with an upper limit on the ionizing luminosity emitted toward Earth provides no evidence that the central ionizing source radiates anisotropically. The images of MCG 8-11-11 show only an unresolved nuclear source. No emission line gas associated with the extended radio source is detected. We estimate upper limits on the intensity of extended line emission in this galaxy and examine their significance.

    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.

Contrary to previous results, we find that warm absorption is not required by the data. Instead, we report upper limits on absorption lines that are below previous (marginal) detections. Fe Kα line emission is clearly detected and is likely resolved with σ ∼ 0.02 keV with the HETG data. We applied self-consistent, broadband spectral-fitting models to the Chandra and Suzaku data to investigate this and other signatures of distant absorption and reflection. Utilizing in particular the MYTorus model, we find that the data are consistent with reprocessing by a distant, neutral torus that is marginally Compton-thick ( N {sub H} ∼10{sup 24}cm{sup –2}) and out of the line of sight. However, we do not find compelling evidence of a relativistically broadened Fe K emission line, which is often expected from type 1 active galactic nuclei. This is consistent with some, although not all, previous studies of MCG +8-11-11. A well-measured edge is identified by the HETG near 0.5 keV, indicating neutral absorption in the line of sight that is consistent with galactic absorption; however, the absorption may be partially intrinsic to the source. The HETG data are consistent with the presence of a soft excess, a feature that may be missed by considering the Suzaku data alone.

    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.

    Background: In China, no multicenter double-blinded prospective randomized controlled study on labor induction has been conducted till now. This study is to evaluate the efficacy and safety of intravaginal accurate 25-μg misoprostol tablets for cervical ripening and labor induction in term pregnancy in nulliparous women. Methods: This was a double-blinded, prospective randomized controlled study including nulliparous women from 6 university hospitals across China. Subjects were randomized into misoprostol or placebo group with the sample size ratio set to 7:2. Intravaginal 25-μg misoprostol or placebo was applied at an interval of 4 h (repeated up to 3 times) for labor induction. Primary outcome measures were the incidence of cumulative Bishop score increases ≥3 within 12 h or vaginal delivery within 24 h. Safety assessments included the incidences of maternal morbidity and adverse fetal/neonatal outcomes. Results: A total of 173 women for misoprostol group and 49 women for placebo were analyzed. The incidence of cumulative Bishop score increases ≥3 within 12 h or vaginal delivery within 24 h was higher in the misoprostol group than in the placebo (64.2% vs. 22.5%, relative risk [RR]: 2.9, 95% confidence interval [CI]: 1.4–6.0). The incidence of onset of labor within 24 h was significantly higher in the misoprostol group than in the placebo group (48.0% vs. 18.4%, RR: 2.6, 95% CI: 1.2–5.7); and the induction-onset of labor interval was significantly shorter in the misoprostol group (P = 0.0003). However, there were no significant differences in the median process time of vaginal labor (6.4 vs. 6.8 h; P = 0.695), incidence (39.3% vs. 49.0%, RR: 0.8, 95% CI: 0.4–1.5) and indications (P = 0.683) of cesarean section deliveries, and frequencies of maternal, fetal/neonatal adverse events between the groups. Conclusion: Intravaginal misoprostol 25 μg every 4 h is efficacious and safe in labor induction and cervical ripening. PMID:26481739

    Epidemiological studies indicate chronic use of non-steroidal anti-inflammatory drugs (NSAIDs), which inhibit the enzymatic activity of the inflammatory cyclooxygenases (COX), reduces the risk of developing Alzheimer's disease (AD) in normal aging populations. Considering multiple adverse side effects of NSAIDs, findings suggest that COX downstream prostaglandin signaling function in the pre-clinical development of AD. Our previous study found that misoprostol, a synthetic prostaglandin E2 (PGE2) receptor agonist, has neuroprotection against brain injury induced by chronic aluminum overload. Here, we investigated the neuroprotective effects and mechanisms of misoprostol on neurodegeneration in overexpressing both amyloid precursor protein (APP) and mutant presenilin 1 (PS1) mice. Here were young group, elderly group, APP/PS1 group and misoprostol-treated group. Mice in misoprostol-treated group were administrated with misoprostol (200 μg·kg-1·d-1, p.o.) five days a week for 20 weeks. The spatial learning and memory function was impaired and karyopycnosis of hippocampal and cortical neurons was observed; amyloid beta (Aβ) deposition was increased; superoxide dismutase (SOD) activity was decreased and malondialdehyde (MDA) content was increased in APP/PS1 mice. However, misoprostol could significantly blunte these changes in APP/PS1 mic. Moreover, the expressions of microsomal PGE2 synthase (mPGES-1), PGE2, PGE2 receptor (EP) 2 and EP4 were increased and EP3 expression was decreased in APP/PS1 mice, while misoprostol reversed these changes. Our present experimental results indicate that misoprostol has a neuroprotective effect on brain injury and neurodegeneration of APP/PS1 mice and that the activation of PGE2-EP3 signaling and inhibition of oxidative stress contribute to the neuroprotective mechanisms of misoprostol.

  8. An absorption origin for the X-ray spectral variability of MCG-6-30-15

    Context: The Seyfert I galaxy MCG-6-30-15 shows one of the best examples of a broad “red wing” of emission in its X-ray spectrum at energies 2 < E < 6.4 keV, commonly interpreted as being caused by relativistically-blurred reflection close to the event horizon of the black hole. Aims: We aim to test an alternative model in which absorption creates the observed spectral shape, explains the puzzling lack of variability of the red wing and reduces the high reflection albedo, substantially greater than unity, that is otherwise inferred at energies E > 20 keV. Methods: We compiled all the available long-exposure, high-quality data for MCG-6-30-15: 522 ks of Chandra hetgs, 282 ks of XMM-Newton pn/rgs and 253 ks of Suzaku xis/pin data. This is the first analysis of this full dataset. We investigated the spectral variability on timescales >20 ks using principal components analysis and fitted spectral models to “flux state” and mean spectra over the energy range 0.5-45 keV (depending on detector). The absorber model was based on the zones previously identified in the high-resolution grating data. Joint fits were carried out to any data that were simultaneous. Results: Multiple absorbing zones covering a wide range of ionisation are required by the grating data, including a highly ionised outflowing zone. A variable partial-covering zone plus absorbed low-ionisation reflection, distant from the source, provides a complete description of the variable X-ray spectrum. A single model fits all the data. We conclude that these zones are responsible for the red wing, its apparent lack of variability, the absorption structure around the Fe Kα line, the soft-band “excess” and the high flux seen in the hard X-ray band. A relativistically-blurred Fe line is not required in this model. We suggest the partial covering zone is a clumpy wind from the accretion disk.

    The bright Seyfert 1 galaxy MCG -6-30-15 shows large variability on a variety of timescales. We study the less, similar3 day timescale variability using a set of simultaneous archival observations that were obtained from the Rossi X-Ray Timing Explorer (RXTE) and the Advanced Satellite for Cosmology and Astrophysics (ASCA). The RXTE observations span nearly 106 s and indicate that the X-ray Fourier power spectral density has an rms variability of 16%, is flat from approximately 10-6 to 10-5 Hz, and then steepens into a power law proportional to f-alpha with alpha greater, similar1. A further steepening to alpha approximately 2 occurs between 10-4 and 10-3 Hz. The shape and rms amplitude are comparable to what has been observed in NGC 5548 and Cyg X-1, albeit with break frequencies that differ by a factor of 10-2 and 104, respectively. If the break frequencies are indicative of the central black hole mass, then this mass may be as low as 106 M middle dot in circle. An upper limit of approximately 2 ks for the relative lag between the 0.5-2 keV ASCA band compared to the 8-15 keV RXTE band was also found. Again by analogy with NGC 5548 and Cyg X-1, this limit is consistent with a relatively low central black hole mass. PMID:10673403

    Background: Misoprostol is a synthetic prostaglandin E1 that induces cervical effacement and uterine contractions at all gestational ages, thus facilitating uterine evacuation and pregnancy termination. Successful medical evacuation of spontaneous miscarriage with minimal adverse effects can be performed using misoprostol-only regimen if given as indicated and if the administered dose, frequency of the dosage, and number of total doses are appropriate. Aim: To conduct a drug use evaluation by investigating indications, appropriateness of dosing, and clinical outcome of misoprostol-only regimen when used for medical evacuation of spontaneous miscarriage at the Women's Hospital in Doha, Qatar. Materials and methods: A retrospective descriptive drug use evaluation was conducted on women with spontaneous miscarriage who received misoprostol for medical evacuation during August 2013. The current practice at the Women's Hospital was compared with the recommendation from the World Health Organization (WHO). Patients were stratified into three groups based on weeks of amenorrhea. Results: A total of 107 patients received misoprostol during August 2013, of which 33 (31%) were included in the study. In these patients, the main indication for misoprostol use was missed miscarriage (54.5%). In the group of patients at ≤ 9 weeks of gestation, 80% received an initial dose of 800 μg, 80% received frequency within the WHO recommendation, and the majority had surgical evacuation (80%). In the group of patients at 10–12 weeks of gestation, more than 80% received an initial dose of 800 μg, 6% received frequency within the WHO recommendation, and more than 75% had successful medical evacuation. In the group of patients at 13–22 weeks of gestation, more than 80% received an initial dose of 400 μg, more than 80% received frequency within the WHO recommendation, and 54% had successful medical evacuation. Overall, more than 70% of the patients received ≤ 3 total doses of

    Misoprostol (MISO) is a synthetic prostaglandin (PG) E/sub 1/ methyl ester with gastric antisecretory and mucosal protective properties. MISO is rapidly de-esterified to misoprostol free acid (MISO-FA) in enriched (65-80%) canine parietal cell preparations. Both forms appear to possess equivalent antisecretory potency and (/sup 3/H) MISO-FA is stable in these preparations. (/sup 3/H) MISO-FA binding was reversible and saturable with a maximal number of binding sites estimated at 8138 +/- 1893 per cell. The scatchard plot was linear, indicating a single, high affinity receptor population with a dissociation constant of 11 +/- 2.6 x 10/sup -9/ M. Unlabeled MISO-FA and MISO were equally potent inhibitors (IC/sub 50/, approx. 10/sup -8/M) of (/sup 3/H) MISO-FA binding. At 10/sup -5/ M, the dinor and tetranor ..beta..-oxidation metabolites of MISO were weak binding inhibitors. Strict stereospecific binding was shown by MISO stereoisomers, and the 11R, 16S isomer was most active. Both PGE/sub 1/ and 16,16 dimethyl PGE/sub 2/ were potent binding inhibitors, but PGF/sub 1/..cap alpha.. (10/sup -6/ M) and Hoe 892 (10/sup -5/ M), a stable PGI/sub 2/ analog, were weak inhibitors. Neither histamine or cimetidine competed for binding sites. These data indicate the presence of stereospecific E-type prostaglandin receptors in enriched canine parietal cell preparations.

    Studies into the mechanism of acetaminophen (APAP)-induced hepatotoxicity have focused mainly at the hepatocellular level. This study aimed to investigate the effect of acetaminophen on the hepatic microvasculature using a vascular casting technique. Acetaminophen was administered at a dose of 650 mg/kg body weight (intraperitoneally) to fasted male Long Evans rats. Microvascular casting was performed at various points after drug administration. Liver casts from control rats showed good patency with normal hepatic microvasculature. Thirty-six hours after overdose with acetaminophen, liver casts showed rounded centrilobular cavities of various sizes, representing regions in which cast-filled sinusoids were absent with relatively normal microvasculature within periportal regions. Evidence of microvascular injury occurred as early as 5 hours after acetaminophen overdose. This injury consisted of changes to centrilobular sinusoids including areas of incomplete filling and dilated centrilobular sinusoids. Misoprostol (a prostaglandin E1 analog) treatment (6 x 25 micrograms/kg) given before and after acetaminophen administration markedly reduced the extent of microvascular injury with only small focal unfilled areas in the casts and a generally intact microvasculature. In conclusion, this study shows that overdosage with APAP resulted in an extensive, characteristic pattern of hepatic microvascular injury in the centrilobular region. The results also suggest that microvascular injury is an early event in the pathogenesis of acetaminophen hepatotoxicity. Misoprostol was found to protect against injury occurring at the microvascular level. PMID:7489988

    Objective To assess the efficacy and safety of vaginal misoprostol after a pretreatment with vaginal estradiol to facilitate the hysteroscopic surgery in postmenopausal women. Methods In this observational comparative study, 35 control women (group A) did not receive any pharmacological treatment,26 women (group B) received 25 µg of vaginal estradiol daily for 14 days and 400 µg of vaginal misoprostol 12 hours before hysteroscopic surgery, 32 women (group C) received 400 µg of vaginal misoprostol 12 hours before surgery. Results Demographic data were well balanced and all variables were not significantly different among the three groups. The study showed a significant difference in the preoperative cervical dilatation among the group B (7.09±1.87 mm), the group A (5.82±1.85 mm; B vs. A, P=0.040) and the group C (5.46±2.07 mm; B vs. C, P=0.007). The dilatation was very easy in 73% of women in group B. The pain scoring post surgery was lower in the group B (B vs. A, P=0.001; B vs. C, P=0.077). In a small subgroup of women with suspected cervical stenosis, there were no statistically significant differences among the three groups considered. No complications during and post hysteroscopy were observed. Conclusion In postmenopausal women the pretreatment with oestrogen appears to have a crucial role in allowing the effect of misoprostol on cervical ripening. The combination of vaginal estradiol and vaginal misoprostol presents minor side effects and has proved to be effective in obtaining satisfying cervical dilatation thus significantly reducing discomfort for the patient.

    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.

    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 and 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.

    Maternal mortality and morbidity are the leading causes of death and illness, respectively, among women of reproductive age in many countries throughout the world. Of all maternal deaths, those related to unsafe abortions are the most widely underestimated, but they are also the most largely preventable. Medical abortion is a safe and reliable method for termination of a pregnancy in early gestation, although it is important to be aware of signs and symptoms of severe infection and toxic shock syndrome after the medical termination of pregnancy; case studies in literature are rarely fatal events. We report the first case of septic shock syndrome following a clandestine pregnancy termination with a misoprostol-only regimen (12 tablets 200 μg each). Autopsy findings and histopathological examination proved that the woman died from septic shock. This case suggests to improve the forensic investigations in case of unsafe, often clandestine, abortion is suspected. PMID:25041279

    The effect of vaginal administration of misoprostol plus terbutaline sulphate 6 h prior to artificial insemination (AI) upon the site of AI (vaginal or cervical) and fertility was studied using a total of 87 estrous synchronized Serra da Estrela ewes (control n = 42 and treated n = 45). Artificial insemination was performed using refrigerated semen at 54-55 h after sponge removal. Lambing rate (fertility) and prolificacy were compared between control and treated ewes. The effect of the site of semen deposition on fertility was also evaluated. Prolificacy rate was not different between control (1.5) and treated (1.59) ewes. The proportion of cervical AI achieved in control (45.2%) and treated (37.8%) ewes was not significantly different. Overall, fertility was significantly lower in control than in treated ewes (42.9% vs 64.4%; p < 0.04). Fertility following vaginal AI was significantly lower for control for than treated ewes (30.4% vs 60.7%; p < 0.03) but the difference was smaller and not significant for cervical AI (control 57.9% vs 70.6%). It was concluded that vaginal administration of misoprostol plus terbutaline sulphate 6 h prior to artificial insemination did not affect the proportion of cervical inseminations but significantly improved the fertility of treated ewes. Although needing confirmation, it was hypothesized that drugs might have induced local secretory modifications leading to an increase of cervical ability to retain more viable spermatozoa for fertilization.

Carriers were examined and questioned regarding their experience of adverse reactions, which were graded 0 to 3 according to severity, at 6, 12 and 24 hours and at 4 days after treatment. Biological examinations which included determination of microfilaraemia, complete blood count, liver function tests and assessment of creatinine and urea levels were performed at 4 days before and 4 days after treatment. Adverse reactions were observed in 65% of female and in 70% of male carriers; they were of grade > or = 2 in 35% of carriers in both groups. None as considered serious; they all disappeared in 24-48 hours. The main symptoms were headache, fever > or = 37.5 degrees C and myalgia in females. One male vomited 3 hours after treatment; as a result the drug was not ingested and no decrease of microfilaraemia was noted. Twelve days afterwards, he was given a second 400 mcg/kg dose, he experienced again a grade 1 reaction and his microfilaraemia fell to zero. The 37 carriers in the present study were matched with 37 other Polynesian carriers treated with a 100 mcg/kg single dose of ivermectin in previous trials for pretreatment mf density and sex: no significant difference could be found in adverse reactions between the 2 treatment groups.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1293733

    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.

    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. PMID:24871787

    Misoprostol is a pharmaceutical synthetic compound, analog of prostaglandin E1, frequently used as an abortifacient in not medically supervised or self-induced abortions, particularly in countries with restrictive abortion laws representing a serious public health problem. The aim of this study was to develop and validate a sensitive analytical method for the determination of misoprostol acid in whole blood samples. The samples were prepared by SPE and the chromatographic separation was performed by UPLC-MS/MS using ESI- and MRM mode with an Acquity UPLC(®) BEH C18 (50mm×2.1mm i.d., 1.7μm) column using a methanol-ammonium 0.1% solution gradient in a total run time of 7.0min. The method showed to be selective and linear in range 25-2000ng/L. The LOD and LOQ were 10ng/L and 25ng/L, respectively. The recovery ranged from 89 to 97%. No carryover and significant matrix effect were observed. The intra- and inter-assay precisions and the inter-assay accuracy results were 4.0% and 5.4%, 5.5% and 4.1%, and -1.4% and -2.8%, for the concentrations 50 and 500ng/L, respectively. The method developed allows the analysis of misoprostol acid in whole blood samples with adequate sensitivity to the concentration range obtained from therapeutic doses. The method was successfully used in a controlled misoprostol administration study and has been applied in our laboratory in the forensic toxicology field. PMID:22940267

    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.

    Background Fibroma, the most common benign pelvic tumor in women, affects 25 to 30% of women of reproductive age. Primary treatment for patients with symptomatic or large fibroma is surgery. Objective The purpose of this study was to investigate the effect of a single rectal dose of Misoprostol on bleeding during abdominal hysterectomy. Methods This double blind randomized clinical trial was conducted with 80 candidates for abdominal hysterectomy, due to uterine myoma, in the Shahid Sadoughi hospital of Yazd in 2012. The aim of this study was to assess the effect of single rectal dose of Misoprostol on peri-operational abdominal hysterectomy bleeding. Following administration of 400 micrograms of Misoprostol in the case group (n=40), predetermined criteria were compared with control group (n=40). Results Volume of bleeding during the operation was significantly lower in cases where Misoprostol was used. (268.71 ± 156.85 vs. 350.38 ± 152.61 cc in the case and control groups, respectively). Our findings also showed that Hemoglobin (Hb) levels before, 8, and 30 hours following the operation differed significantly (p=0.001), but these changes were similar in both groups. Pre-operative Hb levels were 11.90 ± 1.7 and 11.90 ± 2.0 in the case and control groups, respectively. Conclusion A single rectal dose of Misoprostol has positive effect on reducing peri-operational bleeding in women undergoing abdominal hysterectomy due to symptomatic leiomyoma. PMID:26516444

    This paper sought to determine the safety and feasibility of home-based prophylaxis of postpartum hemorrhage (PPH) with misoprostol, including assessment of the need for referrals and additional interventions. In rural Tigray, Ethiopia, traditional birth attendants (TBAs) in intervention areas were trained to administer 600mcg of oral misoprostol. In non-intervention areas women were referred to the nearest health facility. Of the 966 vaginal deliveries attended by TBAs, only 8.9% of those who took misoprostol prophylactically (n = 485) needed additional intervention due to excessive bleeding compared to 18.9% of those who did not take misoprostol (n = 481).The experience of symptoms among those who used misoprostol can be considered of minor relevance and self-contained. This study found that prophylactic use of misoprostol in home births is a safe and feasible intervention. Community health care workers trained in its use can correctly and effectively administer misoprostol and be a champion in reducing PPH morbidity and mortality. PMID:20690252

    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.

    A new X-ray source, H0523-00, with the optically variable Seyfert 1 galaxy AKN 120 is identified. The source has a 2-10 keV X-ray flux of 2 x 10 to the -11th ergs/sq cm s which corresponds to a 2-10 keV X-ray luminosity of 10 to the 44th ergs/s. X-ray observations over a 1.5 year time span combined with contemporaneous optical photometry show a decrease in the optical with no corresponding decrease in the X-ray. In contrast, similar observations of MCG 8-11-11 show a contemporaneous decrease in optical and X-ray fluxes. It is noted that the infrared and X-ray spectral slopes for these two objects are similar, with the optical being steeper by roughly one unit.

    We present the results of the simultaneous deep XMM-Newton and Chandra observations of the bright Seyfert 1.9 galaxy MCG-5-23-16, which is thought to have one of the best known examples of a relativistically broadened iron Kalpha line. We detected a narrow sporadic absorption line at 7.7 keV which appears to be variable on a time-scale of 20 ksec. If associated with FeXXVI this absorption is indicative of a possible variable high ionization, high velocity outflow. The time averaged spectral analysis shows that the iron K-shell complex is best modeled with an unresolved narrow emission component (FWHM less than 5000 kilometers per second, EW approx. 60 eV) plus a broad component. This latter component has FWHM approx. 44000 kilometers per second, an EW approx. 50 eV and its profile is well described with an emission line originating from the accretion disk viewed with an inclination angle approx. 40 deg. and with the emission arising from within a few tens of gravitational radii of the central black hole. The time-resolved spectral analysis of the XMM-Newton EPIC-pn spectrum shows that both the narrow and broad components of the Fe K emission line appear to be constant within the errors. The analysis of the XMM-Newton/RGS spectrum reveals that the soft X-ray emission of MCG-5-23-16 is likely dominated by several emission lines superimposed on an unabsorbed scattered power-law continuum. The lack of strong Fe L shell emission together with the detection of a strong forbidden line in the O VII triplet supports a scenario where the soft X ray emission lines are produced in a plasma photoionized by the nuclear emission.

    Introduction: We undertook a prospective cohort study to compare the effectiveness and safety of 50 µg misoprostol versus 3 mg dinoprostone in two vaginal doses 6 hours apart, followed if necessary by oxytocin for labor induction in low-risk post-term (> 40 weeks) pregnancies with unfavorable cervix (Bishop score ≤ 6). Methods: Labor induction and subsequent management were conducted using a standardized protocol. The primary outcome of the study was labor induction rate. Secondary outcomes included mode of delivery, time interval from induction to delivery, maternal complications and neonatal outcome. Results: 107 patients received misoprostol (Group A) and 99 patients received dinoprostone (Group B). Compared with group A, more women in Group B needed a second vaginal dose of prostaglandin or oxytocin infusion in order to proceed to labor (21.5 vs. 43.4 %; p = 0.01). Misoprostol alone as a single or double vaginal dose was more effective than dinoprostone alone in inducing labor without oxytocin administration (85.0 vs. 50.4 %; p = 0.04). Overall, the rate of successful induction of labor did not differ between groups (91.6 vs. 85.8 %; p = 0.75). Vaginal delivery, operative vaginal delivery and Caesarean section rates were not significantly different. Time interval from induction to delivery however, was shorter for Group A (median 11 hours vs. 14.1 hours; p < 0.001). Though emergency Caesarean section due to fetal distress was more frequent in Group A (16.8 vs. 4.0 %; p = 0.007), low Apgar scores < 7 and NICU admissions did not differ significantly. Maternal complications, mostly not serious, were higher in Group A (31.8 vs. 2.0, p < 0.001). Conclusion: Misoprostol is a more effective agent than dinoprost in post-term pregnancy for labor induction with few maternal adverse effects. PMID:27582576

    2011-01-01

    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. PMID:21340108

    Arthrotec(®) (AT) is a combination of diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), and misoprostol (MP), a synthetic analogue of prostaglandin E1 (PGE1). MP is a lipophilic methyl ester prodrug. It is readily metabolized to the biologically active misoprostol acid (MPA). During the last few years, medical studies exhibited MP to be an excellent abortive. In this paper, we describe a rare criminal case of MP abortion, initiated by the expectant father. After the abortion, samples of vomit and urine were collected. Systemic exposure to MP is difficult to prove, because both MP and the active metabolite MPA are hardly excreted in urine. Therefore, in addition to routine toxicological analysis, we used slightly modified, well-established liquid and gas chromatographic/tandem mass spectrometric (LC/MS/MS and GC/MS/MS) methods, for the direct and the indirect detection of MPA and its metabolites. In this case, we were able to demonstrate the presence of the major MP metabolites 2,3-dinor-MPA and 2,3,4,5-tetranor-MPA in the urine of the victim. We also detected paracetamol, 3-methoxyparacetamol and diclofenac-glucuronide in the urine. In the vomit of the victim, we detected diclofenac and MPA. These results, combined with the criminal investigations, showed that the accused had mixed MP into the food of his pregnant girlfriend. Finally, these investigations contributed to a confession of the accused. PMID:25524762

    We present a study on the dwarf lenticular galaxy MCG+08-22-082 (U141), located in the Ursa Major cluster, blue-centered, double-cored, and having a boxy appearance. Using publicly available data from the Sloan Digital Sky Survey (SDSS), we perform an analysis of the structural and stellar population properties of the galaxy and the cores. We find that the light profile of U141 follows an exponential law. U141 has a brightness of {M}r=-16.01 mag, and an effective radius of {R}e=1.7 {{kpc}}. The boxiness parameter {a}4/a is mostly between 0 and ‑0.05 in the inner parts, reaching an extreme of about ‑0.1. Double cores are seen at the center of U141; each of these cores has a stellar mass of ∼106 M⊙ and the separation between them is ∼300 pc. Optical spectroscopy of these cores shows prominent emission in Hα, suggesting ongoing star-forming activities. We interpret these morphological properties and speculate that U141 is a merger remnant of two disk galaxies. Thus, we might have discovered an intermediate stage of merging, providing possible evidence of double cores in the center of the galaxy.

    The complex anatomy the of ovine cervix limits the success of transcervical artificial insemination in sheep, but Misoprostol (a PGE(1) analogue) relaxes the cervix and facilitates transcervical artificial insemination. However, the mechanism by which Misoprostol causes cervical relaxation is not known. This study examined if intra-cervical Misoprostol altered the hyaluronan content and the mRNA expression of COX-2, LHR, or FSHR in the cervix of the estrus ewe. Estrus was synchronized in cyclic ewes with progestagen pessaries and 48 h after sponge removal ewes were treated intra-cervically with 0 (controls), 200, or 400 microg Misoprostol. Hyaluronan content was determined by ELISA and mRNA expression of LHR, FSHR, and COX-2 was analyzed by in situ hybridization using digoxigenin-11-uridine-5'-triphosphate labeled riboprobes. The hyaluronan content of the cervix was significantly higher in sheep that received 200 (P<0.05) or 400 (P<0.05) microg Misoprostol compared to controls. Moreover, it was significantly (P<0.05) higher in the vaginal region compared to mid and uterine regions. Misoprostol increased (P<0.05) the mRNA expression of LHR and COX-2 but not FSHR. The expression for all three genes was highest in the vaginal region and lowest in uterine region. The luminal epithelium and circular smooth muscle layers had higher (P<0.05) expression for LHR, FSHR, and COX-2 mRNAs, and the sub-epithelial stroma had the lowest (P<0.05). We propose that the intra-cervical application of Misoprostol induces the mRNA expression of LHR, FSHR, and COX-2 through a positive feedback loop. The data suggest that softening of the cervix by Misoprostol is caused by an increase in the hyaluronan content of the cervix. PMID:20171717

    Background Postpartum hemorrhage (PPH) is a leading cause of maternal death in sub-Saharan Africa. Although the World Health Organization recommends use of oxytocin for prevention of PPH, misoprostol use is increasingly common owing to advantages in shelf life and potential for sublingual administration. There is a lack of data about the comparative efficacy of oxytocin and sublingual misoprostol, particularly at the recommended dose of 600 µg, for prevention of PPH during active management of labor. Methods and Findings We performed a double-blind, double-dummy randomized controlled non-inferiority trial between 23 September 2012 and 9 September 2013 at Mbarara Regional Referral Hospital in Uganda. We randomized 1,140 women to receive 600 µg of misoprostol sublingually or 10 IU of oxytocin intramuscularly, along with matching placebos for the treatment they did not receive. Our primary outcome of interest was PPH, defined as measured blood loss ≥500 ml within 24 h of delivery. Secondary outcomes included measured blood loss ≥1,000 ml; mean measured blood loss at 1, 2, and 24 h after delivery; death; requirement for blood transfusion; hemoglobin changes; and use of additional uterotonics. At 24 h postpartum, primary PPH occurred in 163 (28.6%) participants in the misoprostol group and 99 (17.4%) participants in the oxytocin group (relative risk [RR] 1.64, 95% CI 1.32 to 2.05, p<0.001; absolute risk difference 11.2%, 95% CI 6.44 to 16.1). Severe PPH occurred in 20 (3.6%) and 15 (2.7%) participants in the misoprostol and oxytocin groups, respectively (RR 1.33, 95% CI 0.69 to 2.58, p = 0.391; absolute risk difference 0.9%, 95% CI −1.12 to 2.88). Mean measured blood loss was 341.5 ml (standard deviation [SD] 206.2) and 304.2 ml (SD 190.8, p = 0.002) at 2 h and 484.7 ml (SD 213.3) and 432.8 ml (SD 203.5, p<0.001) at 24 h in the misoprostol and oxytocin groups, respectively. There were no significant differences between the two groups in any other

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.

    Long term use of low doses of combination oral contraceptives appears to increase plasminogen level, thereby increasing fibrinolytic activity and reducing the risk of thromboembolism. Blood levels of plasminogen, tissue plasminogen activator (tPA), and plasminogen activator inhibitor (PAI), were measured before and after stress (5 minutes of stair climbing) in a group of 30 women, 23-40 years old, who had taken 30 mcg of ethinyl estradiol with 150 mcg of desogestrel or levonorgestrel for at least 1 year. Similar measurements were taken from a control group of 30 women matched for age, height, and weight. Plasminogen and tPA levels in both groups increased significantly after exercise. The level of PAI did not change significantly with stress in either group. The level of plasminogen was significantly higher in the group taking contraceptives, whether before or after exercise, when compared to the control group. Levels of tPA and PAI, although slightly increased in the oral contraceptive group, were not significantly different between the two groups. The increase in plasminogen may be due to the estrogen component of the contraceptives. Stress seems to increase fibrinolytic response. PMID:12345026

    Several X-ray observations have recently revealed the presence of reverberation time delays between spectral components in active galactic nuclei. Most of the observed lags are between the power-law Comptonization component, seen directly, and the soft excess produced by reflection in the vicinity of the black hole. NGC 4151 was the first object to show these lags in the iron K band. Here, we report the discovery of reverberation lags in the Fe K band in two other sources: MCG-5-23-16 and NGC 7314. In both objects, the 6-7 keV band, where the Fe K{alpha} line peaks, lags the bands at lower and higher energies with a time delay of {approx}1 ks. These lags are unlikely to be due to the narrow Fe K{alpha} line. They are fully consistent with reverberation of the relativistically broadened iron K{alpha} line. The measured lags, their time scale, and spectral modeling indicate that most of the radiation is emitted at {approx}5 and 24 gravitational radii for MCG-5-23-16 and NGC 7314, respectively.

    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

    Findings on women's sexuality across the menstrual cycle are inconsistent. One relatively consistent finding is a midcycle and premenstrual peak in sexual desire in freely cycling women. Results on the cycle-related effects on sexual behavior are less clear. Large proportions of reproductive-aged women use combined oral contraception (COC), but studies on potential cycle-related shifts in sexual desire and behavior are sparse. A prospective diary study assessed sexual desire, sexual behavior, and mood in 89 heterosexual couples. Women were using one of four contraceptive methods: (1) nonhormonal contraception, (2) low-dose COC containing 20 mcg ethinylestradiol and 75 mcg gestoden or desogestrel, (3) COC containing 35 mcg ethinylestradiol and 2 mg cyproteronacetate, and (4) COC containing 30 mcg ethinylestradiol and 3 mg drospirenone. No cycle effects of sexual desire were established in the COC group, but frequency of sexual intercourse declined in the last days of active pill taking. These results were similar in both female and male partners. Negative affect did not covary with sexual desire. PMID:25420716

    Ulcers commonly occur in the oral cavity, their main symptom being pain. There are different ways to classify oral ulcers. The most widely accepted form divides them into acute ulcers--sudden onset and short lasting--and chronic ulcers--insidious onset and long lasting. Commonest acute oral ulcers include traumatic ulcer, recurrent aphthous stomatitis, viral and bacterial infections and necrotizing sialometaplasia. On the other hand, oral lichen planus, oral cancer, benign mucous membrane pemphigoid, pemphigus and drug-induced ulcers belong to the group of chronic oral ulcers. It is very important to make a proper differential diagnosis in order to establish the appropriate treatment for each pathology. PMID:16277953

    The budgetary impact of prescribing a combined formulation of diclofenac sodium and misoprostol to patients previously using nonsteroidal anti-inflammatory agents (NSAIDs), cytoprotective agents, or a combination of agents from both therapeutic categories is assessed, as is the clinical rationale for prescribing the combined formulation. Analysis of data for Canada on claims paid by third parties showed that the use of the combined formulation in Canada had resulted in significant initial overall savings and that the greatest cost savings were made for those who had previously used both an NSAID and a cytoprotective concomitantly. The inclusion of shadow costs (secondary costs) indicates that the use of the combined formulation over a 6-month period involves very low shadow costs (medical expenses related to ulcer treatment) compared with other NSAIDs: the shadow cost multiplication factor was 1.03 for the combined formulation compared with 1.22 to 3.47 for other NSAIDs. Pharmaceutical costs alone are insufficient for evaluating total budgetary impacts. PMID:8746611

    Researchers compared the results of hematocrit and blood viscosity tests of 16 women using a combined oral contraceptive (COC) with 30 mcg ethinyl estradiol/150 mcg desogestrel (group 1), 11 women using a COC with 30 mcg ethinyl estradiol/150 mcg levonorgestrel (group 2), and 16 women who did not use any OCs (control group), all who attended the National Population and Family Development Clinic at the General Hospital in Kuala Lumpur, Malaysia. They wanted to examine the effects of COCs on blood viscosity, which is inversely related to blood flow, and hematocrit. The women were matched for age. The hematocrit level of women who took the ethinyl estradiol/desogestrel COC was significantly higher than that of the control group (41.5% vs. 37.4%; p.001). On the other hand, the hematocrit level of women who took the ethinyl estradiol/levonorgestrel COC was close to that of the control group (38.5% vs. 37.4%). Even though the mean whole blood viscosity for group 2 was higher than that of group 1 and the control group (6.6 cps vs. 5.5 cps), the difference was insignificant. Yet whole blood viscosity of group 2 at the higher shear rates (46, 115, and 230 per second) was significantly higher than the control group (p.05). The whole blood viscosities of group 1 and the control group did not differ considerably. This supported the theory that hematocrit contributes to blood viscosity. Further these results agreed with those of another study which also showed increased blood viscosity and hematocrit in healthy women taking OCs. Thus thromboembolic events in women taking OCs could be a result of a drop in rate of blood flow which at the lower shear rates could increase red cell aggregation and clotting. In conclusion, health providers could use these indicators to monitor women who have used OCs over a considerable period for thrombotic risks to determine if OC use should continue. PMID:12317443

  10. MCG101-induced cancer anorexia-cachexia features altered expression of hypothalamic Nucb2 and Cartpt and increased plasma levels of cocaine- and amphetamine-regulated transcript peptides.

    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. PMID:26780979

    Extensive evidence exists regarding the efficacy and acceptability of medical abortion through 63 days since last menstrual period (LMP). In Mexico City's Secretariat of Health (SSDF) outpatient facilities, mifepristone-misoprostol medical abortion is the first-line approach for abortion care in this pregnancy range. Recent research demonstrates continued high rates of complete abortion through 70 days LMP. To expand access to legal abortion services in Mexico City (where abortion is legal through 12 weeks LMP), this study sought to assess the efficacy and acceptability of the standard outpatient approach through 70 days in two SSDF points of service. One thousand and one women seeking pregnancy termination were enrolled and given 200 mg mifepristone followed by 800 μg misoprostol 24-48 hours later. Women were asked to return to the clinic one week later for evaluation. The great majority of women (93.3%; 95% CI: 91.6-94.8) had complete abortions. Women with pregnancies ≤ 8 weeks LMP had significantly higher success rates than women in the 9th or 10th weeks (94.9% vs. 90.5%; p = 0.01). The difference in success rates between the 9th and 10th weeks was not significant (90.0% vs. 91.2%; p = 0.71). The majority of women found the side effects (82.9%) and the use of misoprostol (84.4%) to be very acceptable or acceptable. This study provides additional evidence supporting an extended outpatient medical abortion regimen through 10 weeks LMP. PMID:25702071

    Objective This study aimed to assess women´s acceptability of diagnosis and treatment of incomplete abortion with misoprostol by midwives, compared with physicians. Methods This was an analysis of secondary outcomes from a multi-centre randomized controlled equivalence trial at district level in Uganda. Women with first trimester incomplete abortion were randomly allocated to clinical assessment and treatment with misoprostol by a physician or a midwife. The randomisation (1:1) was done in blocks of 12 and stratified for health care facility. Acceptability was measured in expectations and satisfaction at a follow up visit 14–28 days following treatment. Analysis of women’s overall acceptability was done using a generalized linear mixed-effects model with an equivalence range of -4% to 4%. The study was not masked. The trial is registered at ClinicalTrials.org, NCT 01844024. Results From April 2013 to June 2014, 1108 women were assessed for eligibility of which 1010 were randomized (506 to midwife and 504 to physician). 953 women were successfully followed up and included in the acceptability analysis. 95% (904) of the participants found the treatment satisfactory and overall acceptability was found to be equivalent between the two study groups. Treatment failure, not feeling calm and safe following treatment, experiencing severe abdominal pain or heavy bleeding following treatment, were significantly associated with non-satisfaction. No serious adverse events were recorded. Conclusions Treatment of incomplete abortion with misoprostol by midwives and physician was highly, and equally, acceptable to women.

    Introduction Une étude a été menée afin de déterminer le taux d'acceptabilité de 400µg de misoprostol par voie sublinguale comme traitement de première intention de l'avortement incomplet et de préciser le taux d'avortement complet ou vacuité utérine. Méthodes Les femmes éligibles avaient un diagnostic clinique d'avortement incomplet avec une taille utérine inférieure à celle d'un utérus de 12 semaines d'aménorrhées (SA). Chacune a reçu 400µg de misoprostol par voie sublinguale. Les femmes ont été revues après une semaine. A J7, celles qui n'avaient pas complètement expulsé ont eu le choix entre une nouvelle consultation de suivi à J14 et la pratique d'une évacuation chirurgicale immédiate. Résultats 145 patientes ont été éligibles et ont toutes accepté la méthode (100%). L’âge moyen était de 25,9 ± 6 ans. A J7, 120 patientes étaient guéries (85,7%). A J14, le taux de réussitea été de 95,7% soit 134 patientes guéries. Les patientes guéries ont déclaré être très satisfaites (57,5%), satisfaites (41,8%) et insatisfaite (0,7%). Au total,128 femmes (95,5%) ont dit être prêtes à utiliser de nouveau le misoprostol comme méthode d’évacuation utérine en cas d'avortement incomplet. Conclusion L’étude démontre que le 400µg misoprostol par voie sublinguale nous permet de prendre en charge d'une manière adéquate l'avortement incomplet surtout dans les pays à faible ressource et notamment dans les structures sanitaires de première ligne ou éloignées.

    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.

    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. 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.

    The antithrombotic drug heparin is administered parenterally and believed not effective orally. Oral heparin would be most suitable for long term administration, often required for the prevention of thrombosis. Following parenteral administration, heparin is taken up by endothelial cells. Our laboratory has shown that heparin is similarly taken up by endothelium following oral administration, despite low plasma heparin concentrations. In a twenty-four hour period, endothelial heparin concentrations are greatest within 15 minutes of oral dosing although plasma levels never exceed one percent of dose. Endothelial uptake accounts for a considerable amount of absorption if the total body endothelium is considered. In support of oral heparin absorption, we demonstrated a dose-dependent decrease in thrombosis incidence in a rat jugular vein model following single oral doses of unfractionated heparins (bovine and porcine) or low molecular weight heparins (reviparin, logiparin and ardeparin). Low molecular weight heparins were effective at lower doses than unfractionated heparins where a fifty percent reduction in thrombosis was observed with 0.025 mg/kg reviparin, 0.1 mg/kg logiparin, versus 7.5 mg/kg bovine unfractionated heparin. These studies support the work of others demonstrating measurable systemic changes following oral heparin administration and suggest that heparin may be effective when administered by the oral route. It also indicates that the presence of heparin in plasma likely reflects a much greater amount associated with endothelium. PMID:11934211

    Cenesthopathy is characterized by abnormal and strange bodily sensations and is classified as a 'delusional disorder, somatic type' or 'somatoform disorder' according to the DSM 5. The oral cavity is one of the frequent sites of cenesthopathy, thus the term 'oral cenesthopathy.' Patients with oral cenesthopathy complain of unusual sensations without corresponding abnormal findings in the oral area, such as excessive mucus secretion, a slimy sensation, or a feeling of coils or wires being present within the oral region. They usually visit multiple dentists rather than psychiatrists. Without a proper diagnosis, they repeatedly pursue unnecessary surgical procedures to remove their 'foreign body'. This sometimes creates a dilemma between the dentists and patients. The nosography of oral cenesthopathy has been discussed in some case reports and reviews but is overlooked in mainstream medicine. This review focuses on the various aspects of oral cenesthopathy. The estimated prevalence of cenesthopathy was 0.2 to 1.9 % in a study done at a Japanese university psychiatry clinic and 27 % in a study done at a Japanese psychosomatic dentistry clinic. Oral cenesthopathy do not have clear disposition, while some studies reported that elderly women were most commonly affected. Its pathophysiology has not been fully elucidated. However, recent studies have suggested a right > left asymmetrical pattern of the cerebral blood flow of patients with oral cenesthopathy. Antidepressants, antipsychotic drugs, electroconvulsive therapy, and psychotherapy might be effective in some cases, though it is known to be intractable. To date, the epidemiology, pathophysiology, etiology, classification and treatment of oral cenesthopathy are unknown due to the few reports on the disorder, though there are a few case reports. To overcome this difficult medical condition, clinico-statistical and case-control studies done under rigorous criteria and with a large sample size are required. PMID

    Context: Establishing a near perfect surgical field during functional endoscopic sinus surgery (FESS) is essential and even a minor bleeding can severely compromise an already restricted view. So, if controlled hypotension can be provided without compromising the safety of patient by a relatively effortless method, surgical field can be improved greatly. Aims: The aim of this study was to compare the hemodynamic changes and surgical conditions during FESS following oral premedication with clonidine and metoprolol. Settings and Design: A total of 40 patients undergoing FESS were included in this prospective, randomized controlled study. Subjects and Methods: Patients were divided into two equal groups. Group A patients were premedicated with oral clonidine 300 mcg and Group B with oral metoprolol 50 mg, 2 h before surgery. All patients received fentanyl 2 mcg/kg and induced with propofol 2 mg/kg. Intubation was done following vecuronium 1 mg/kg. Anesthesia was maintained with 66% N2O, 33% O2 and 1% isoflurane. The heart rate (HR) and blood pressure (BP) were measured before induction and thereafter every 15 min up to 2 h. The surgeons were asked to estimate the quality of the operative field using a pre-defined category scale with scores 1-5. Statistical Analysis: Difference within the groups was analyzed using analysis of variance and post-hoc test was used to test the difference between individual groups. Chi-square test was used to find out the association between categorical variables. Results: Comparison of category scale revealed a lower score in Group A up to 60 min. Group B patients showed a statistically lower HR from pre-induction up to 90 min while systolic BP (SBP), diastolic BP (DBP) and mean arterial pressure did not show a significant difference. Conclusions: Oral premedication with 300 mcg of clonidine produced a better operative field than oral metoprolol 50 mg during FESS. PMID:25885986

    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.

    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.

    Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options. PMID:27343964

    Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases. The use of a toothbrush is the most important measure for oral hygiene. Toothbrushes with soft bristles operated carefully by hand or via an electric device help to remove plaque and to avoid mucosal trauma. A handlebar with a grip cover can be helpful for manually disabled patients or for those with reduced motor skills. In case of oral hygiene at the bedside or of patients during/after chemo-/radiotherapy a gauze pad can be helpful for gently cleaning the teeth, gums and tongue. The use of fluoride toothpaste is imperative for the daily oral hygiene. Detergents such as sodium lauryl sulphate improve the cleaning action but may also dehydrate and irritate the mucous membrane. The use of products containing detergents and flavouring agents (peppermint, menthol, cinnamon) should therefore be avoided by bedridden patients or those with dry mouth and sensitive mucosa. Aids for suitable interdental cleaning, such as dental floss, interdental brushes or dental sticks, are often complicated to operate. Their correct use should be instructed by healthcare professionals. To support dental care, additional fluoridation with a fluoride gel or rinse can be useful. Products further containing antiseptics such as chlorhexidine or triclosan reduce the quantity of bacteria in the mouth. For patients undergoing or having undergone radio-/chemotherapy, a mouthwash that concomitantly moisturizes the oral mucosa is advisable. PMID:21325845

    Posaconazole oral suspension (PCZ-susp) can display a variable degree of inter and intra-individual absorption. However, there is no agreement on the need of plasma-posaconazole-concentration (PPC) monitoring as a routine practice in patients receiving PCZ-susp. In this prospective, multicenter study we evaluated the variability of PPCs in hematologic patients receiving PCZ-susp prophylaxis with the aim to define conditions at different risk of subtherapeutic PPCs. Overall, 103 acute leukemia (AL) patients submitted to intensive chemotherapy (115 courses) and 46 allogeneic stem cell transplant (allo-SCT) recipients (47 courses) receiving PCZ-susp prophylaxis were considered. The adequacy of PPC pattern after the steady state (≥day 7 of treatment) in courses with two or more PPC measurements was defined as follows: inadequate pattern: PPC < 0.5 mcg/ml at least once; borderline pattern: PPC always ≥0.5mcg/ml but < 0.7 mcg/ml at least once; adequate pattern: PPC always ≥0.7 mcg/ml. The PPC pattern was evaluable in 83 and 37 AL and allo-SCT patients, respectively. It was adequate, borderline and inadequate in 63.9%, 14.5%, and 21.7% of courses, respectively, in AL, and in 62.2%, 10.8%, and 27.0% of courses, respectively, in allo-SCT. In both groups, an inadequate PPC pattern was associated with the development of diarrhea. In absence of diarrhea, the probability of an inadequate PPC pattern was 11.9% in AL and 17.2% in allo-SCT patients. PCZ-susp might be used without stringent need of PPC monitoring in patients without diarrhea. PMID:26868905

    The pharmacokinetics of IV and oral cephradine in healthy young male and female volunteers (ages 19 to 25, n = 10) were compared to those of older individuals (ages 65 to 81, n = 9). Subjects received 1 gram of cephradine by a 5-minute intravenous (IV) infusion followed the next day by a 1-gram oral dose. Serial serum and urine samples collected over a period of 12 hours after the dose were analyzed for cephradine concentration by a microbiologic assay. After IV administration, mean serum cephradine concentrations in the elderly group were significantly higher at both 6 hours (1.52 +/- 0.41 mcg/mL) and 8 hours (0.73 +/- 0.22 mcg/mL) than in the young group at 6 hours (0.43 +/- 0.11 mcg/mL). Total systemic clearance was significantly lower (2.64 +/- 0.34 vs. 4.81 +/- 0.59 ml/min/kg) and the elimination half-life was significantly longer (1.71 +/- 0.20 vs 1.12 +/- 0.13 hours) in the elderly group (P = .0001). Systemic cephradine clearance correlated positively with creatinine clearance (r2 = 0.34, P = .0110) and negatively with age (r2 = 0.79, P = .0052). The mean volume of distribution was not significantly different between the two groups. Mean renal clearance was significantly lower in the elderly group (P = .0001), but more than 80% of the dose was excreted in the urine within 6 hours in both groups. After oral administration, the mean peak concentration and time to peak concentration did not differ between groups. The relative oral bioavailability was approximately 94% in both groups. The mean serum concentrations in the elderly were higher at both 6 and 8 hours than in the young group at 6 hours. There were no differences in pharmacokinetic parameters between male and female subjects. Because of reduced cephradine clearance secondary to an age-related decline in renal function, administration of cephradine every 8 hours, rather than every 6 hours, may be sufficient in elderly patients.

    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). Conclusion Both increasing the OC dose and continuous dosing appear to counteract the impact

    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

    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

    Oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. The various type of oral sex practices are fellatio, cunnilingus and analingus. Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex. PMID:20300419

    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.

    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.

    Etiology control is the most important primary prevention of oral cancer. The use of tobacco and alcohol increases the risk of a squamous cell carcinoma of the oral mucosa. The dentist can play an important role in the secondary prevention or screening for premalignant lesions, asymptomatic malignancies and second primary tumours of the oral cavity. Because of their age, edentulous patients run a high risk of oral cancer. Therefore, a regular oral check-up of these patients should be recommended. PMID:11830977

    Studies focusing on the relationship between oral contraceptive (OC) usage and occurrence of thromboembolism have been conducted for over 3 decades. Those studies centered on the effects OC use has on blood proteins and on measurable physiological changes that occurred in women with venous thrombosis. This article reports the findings of a study that investigated the effects of OC use on the levels of the anticoagulants antithrombin-III (AT-III), protein C (PC), and protein S (PS) in a group of Asian women. Previous studies had mostly been based on Caucasian women. Of the 21 women studied, 16 were Malaysian, 3 were Chinese, and 2 were Indian. Low-dose OCs containing 30 mcg of ethinyl estradiol and 150 mcg of either desogestrel or levonorgestrel were used. Blood was tested before OC use and 3 and 6 months after starting OC use. Levels of AT-III and PS were measured using the Laurell rocket immunoelectrophoresis technique. Statistical analysis was performed using the paired Student's t-test and an analysis of variance test. No statistically significant differences were found for the mean levels of AT-III and total PS when comparing the pre-OC with the 3- and 6-month post-OC values. Earlier studies based mostly on Caucasian women have reported lower levels of both total PS and free PS in OC users. PMID:12288974

    We present long-term monitoring of MCG-6-30-15 in X-rays, optical and near-IR wavelengths, collected over 5 yr of monitoring. We determine the power spectrum density of all the observed bands and show that after taking into account the host contamination similar power is observed in the optical and near-IR bands. There is evidence for a correlation between the light curves of the X-ray photon flux and the optical B band, but it is not possible to determine a lag with certainty, with the most likely value being around 0 d. Strong correlation is seen between the optical and near-IR bands. Cross-correlation analysis shows some complex probability distributions and lags that range from 10 to 20 d, with the near-IR following the optical variations. Filtering the light curves in frequency space shows that the strongest correlations are those corresponding to the shortest time-scales. We discuss the nature of the X-ray variability and conclude that this is intrinsic and cannot be accounted for by absorption episodes due to material intervening in the line of sight. It is also found that the lags agree with the relation τ ∝ λ4/3, as expected for an optically thick geometrically thin accretion disc, although for a larger disc than that predicted by the estimated black hole mass and accretion rate in MCG-6-30-15. The cross-correlation analysis suggests that the torus is located at ˜20 light-days from the central source and at most at ˜50 light-days from the central region. This implies an active galactic nucleus bolometric luminosity of ˜3 × 1043 erg s-1 cm-2.

    To determine the effect of glucose loading on serum zinc concentrations, 34 elderly subjects aged 60-86 y were studied. Anthropometric data, medical and dietary histories were obtained. Serum zinc and glucose concentrations were obtained fasting and 1/2, 1, 1 1/2, 2 and 3 h after 75 g oral glucose load; glycohemoglobin and fasting serum lipids were also determined. For comparison, the subjects were categorized as: normal or low serum zinc concentrations; normal or high body mass index BMI; normal or high sum of skinfolds and normal or high serum cholesterol. Results showed that low serum zinc concentrations increased significantly over baseline values after the glucose load and did not return to fasting levels. On the other hand, mean serum zinc concentrations significantly declined without recovery for those with normal zinc values. For the total group, no significant differences were noted between fasting values and subsequent time periods. No correlations were noted between fasting serum zinc and area under the curve for zinc except in the high BMI group (positive correlation observed). For the high BMI group, fasting serum zinc differed significantly from the succeeding measurements except for 30 min. For the group as a whole, mean serum zinc concentration was within normal limits (76.9 +/- 2.8 mcg/ml): mean zinc intake was less than 2/3rds the RDA. They conclude that glucose ingestion may alter serum zinc and should be considered in interpreting these levels.

    Oral cancer is one of the 10 most common cancers in the world, with a delayed clinical detection, poor prognosis, without specific biomarkers for the disease and expensive therapeutic alternatives. This review aims to present the fundamental aspects of this cancer, focused on squamous cell carcinoma of the oral cavity (OSCC), moving from its definition and epidemiological aspects, addressing the oral carcinogenesis, oral potentially malignant disorders, epithelial precursor lesions and experimental methods for its study, therapies and future challenges. Oral cancer is a preventable disease, risk factors and natural history is already being known, where biomedical sciences and dentistry in particular are likely to improve their poor clinical indicators.

    Montelukast, a specific cysteinyl leukotriene receptor antagonist, has been shown to improve pulmonary function within 1 h of ingestion. This study was undertaken to compare the effects on peak expiratory flow rate (PEFR) of oral montelukast added to intravenous steroid, intravenous steroid alone and placebo during the 24 h period following administration. Seventy asthmatic patients (FEV1 40-80% predicted and > or = 15% improvement after inhaled beta agonist) were enrolled in a single blind study to receive oral montelukast (10 mg) plus intravenous prednisolone (1 mg/kg), intravenous prednisolone (1 mg/kg) or placebo in a randomised fashion. The patients received one ofthe above three groups of medication before any other treatments. This was immediately followed by the aerosol treatments of 100 mcg of terbutaline sulphate divided into three doses during 1 h as described in the consensus statement. Thereafter, patients were observed for 24 h to document the effects on PEFR, Borg dyspnoea score and need for rescue medication. The primary end point was percentage change at different time points. Secondary end points were Borg dyspnoea score and use of rescue medication. Compared with placebo, montelukast added to the prednisolone group and the prednisolone alone group had significant percentage change from baseline in PEFR in the entire 24 h period (P<0.05). The difference in PEFR between montelukast plus prednisolone group and prednisolone group favoured the montelukast plus prednisolone group but did not reach statistical significance. Furthermore, montelukast plus prednisolone group required less inhaled short-acting beta agonistthan other two groups. The results of this study indicate that adding montelukast to steroid in acute asthma may have some additive improvement in lung functions. PMID:12735671

    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

    Introduction Colposcopy is an important diagnostic tool in the evaluation of patients with abnormal pap smears. However, in 10-20% transformation zone (TZ)/squamo-columnar junction is not completely visualized and these patients are deemed to have an incomplete colposcopy examination. Such patients usually require conization, a procedure associated with significant morbidity. Various agents like misoprostol, estrogens and laminaria tents have been used in the past to overcome the non-visualization of TZ. Aim The present study was conducted with the aim to compare the efficacy of vaginal versus oral estradiol administration in overcoming incomplete colposcopy. Materials and Methods Forty patients with non/partially visualized TZ during colposcopy were recruited for the study. These patients were randomly distributed into two groups: In Group I, 25μg estradiol was administered intravaginally daily for seven consecutive days followed by a repeat colposcopy on day 8. In Group II, a seven day course of 25μg oral estradiol was followed by a repeat colposcopy on day 8. The efficacy of the two regimens in improving visualization of the TZ on colposcopy and their adverse effect profile was compared. Results Vaginal estradiol had an overall efficacy of 70% in improving visualization of the TZ as compared to oral estradiol which was effective in 50% of patients (p-value-0.19). Major adverse effects in both the group of patients were nausea and vaginal discharge with no significant differences among the two groups. Conclusion Both vaginal and oral estrogens had comparable efficacy and similar adverse effect profile in improving visualization of the TZ.

  7. Oral microbiota and cancer

    PubMed Central

    2010-01-01

    Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect. Nevertheless, oral microorganisms inevitably up-regulate cytokines and other inflammatory mediators that affect the complex metabolic pathways and may thus be involved in carcinogenesis. Poor oral health associates statistically with prevalence of many types of cancer, such as pancreatic and gastrointestinal cancer. Furthermore, several oral micro-organisms are capable of converting alcohol to carcinogenic acetaldehyde which also may partly explain the known association between heavy drinking, smoking, poor oral health and the prevalence of oral and upper gastrointestinal cancer. A different problem is the cancer treatment-caused alterations in oral microbiota which may lead to the emergence of potential pathogens and subsequent other systemic health problems to the patients. Hence clinical guidelines and recommendations have been presented to control oral microbiota in patients with malignant disease, but also in this area the scientific evidence is weak. More controlled studies are needed for further conclusion. PMID:21523227

    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. PMID:25871419

  9. Global Oral Health Inequalities

    2011-01-01

    Despite impressive worldwide improvements in oral health, inequalities in oral health status among and within countries remain a daunting public health challenge. Oral health inequalities arise from a complex web of health determinants, including social, behavioral, economic, genetic, environmental, and health system factors. Eliminating these inequalities cannot be accomplished in isolation of oral health from overall health, or without recognizing that oral health is influenced at multiple individual, family, community, and health systems levels. For several reasons, this is an opportune time for global efforts targeted at reducing oral health inequalities. Global health is increasingly viewed not just as a humanitarian obligation, but also as a vehicle for health diplomacy and part of the broader mission to reduce poverty, build stronger economies, and strengthen global security. Despite the global economic recession, there are trends that portend well for support of global health efforts: increased globalization of research and development, growing investment from private philanthropy, an absolute growth of spending in research and innovation, and an enhanced interest in global health among young people. More systematic and far-reaching efforts will be required to address oral health inequalities through the engagement of oral health funders and sponsors of research, with partners from multiple public and private sectors. The oral health community must be “at the table” with other health disciplines and create opportunities for eliminating inequalities through collaborations that can harness both the intellectual and financial resources of multiple sectors and institutions.

    Cancer is now the leading cause of death in Japan. A rapid increase in cancer mortality is expected as Japan is facing a super-aged society. Many causes of cancer are known to be closely linked to life style factors, such as smoking, drinking, and diet. The oral environment is known to be involved in the pathogenesis and development of various diseases such as bronchitis, pneumonia, diabetes, heart disease, and dementia. Because the oral cavity acts as the bodily entrance for air and food, it is constantly exposed to foreign substances, including bacteria and viruses. A large number of bacteria are endemic to the oral cavity, and indigenous oral flora act to prevent the settlement of foreign bacteria. The oral environment is influenced by local factors, including dental plaque, tartar, teeth alignment, occlusion, an incompatible prosthesis, and bad lifestyle habits, and systemic factors, including smoking, consumption of alcohol, irregular lifestyle and eating habits, obesity, stress, hormones, and heredity. It has recently been revealed that the oral environment is associated with cancer. In particular, commensal bacteria in the oral cavity are involved in the development of cancer. Moreover, Candida, human papilloma virus and Epstein-Barr virus as well as commensal bacteria have been reported to be associated with the pathogenesis of cancer. In this review, we introduce recent findings of the correlation between the oral environment and cancer. PMID:27482300

    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. PMID:23966202

    Oral sex is commonly practiced by sexually active couples of various age groups, including male-female and same-gender adolescents. The various type of oral sex practices are fellatio, cunnilingus, and analingus. Oral sex can transmit oral, respiratory, and genital infections from one site in body to the other. Oral health has a direct correlation on the transmission of infection; a cut in the mouth, bleeding gums, lip sores or broken skin increases chances of life-threatening infections. Although oral sex is considered a low risk activity, it is important to use protection such as physical barriers, health and medical issues, ethical issues, and oral hygiene and dental issues. The ulcerations or unhealthy periodontium in mouth accelerates the phenomenon of transmission of infections into the circulation. Thus, consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex. PMID:26692602

    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. PMID:11486666

    The field of "salivary diagnostics" includes studies utilizing samples obtained from a variety of sources within the oral cavity. These samples include; whole unstimulated saliva, stimulated whole saliva, duct saliva collected directly from the parotid, submandibular/sublingual glands or minor salivary glands, swabs of the buccal mucosa, tongue or tonsils, and gingival crevicular fluid. Many publications state "we collected saliva from subjects" without fully describing the process or source of the oral fluid. Factors that need to be documented in any study include the time of day of the collection, the method used to stimulate and collect the fluid, and how much fluid is being collected and for how long. The handling of the oral fluid during and post-collection is also critical and may include addition of protease or nuclease inhibitors, centrifugation, and cold or frozen storage prior to assay. In an effort to create a standard protocol for determining a biomarker's origin we carried out a pilot study collecting oral fluid from 5 different sites in the mouth and monitoring the concentrations of pro- and anti-inflammatory cytokines detected using MesoScaleDiscovery (MSD) electrochemiluminesence assays. Our data suggested that 3 of the cytokines are primarily derived from the submandibular gland, while 7 of the cytokines come from a source other than the major salivary glands such as the minor salivary glands or cells in the oral mucosae. Here we review the literature on monitoring biomarkers in oral samples and stress the need for determining the blood/saliva ratio when a quantitative determination is needed and suggest that the term oral diagnostic be used if the source of an analyte in the oral cavity is unknown.

    We investigated age-26 personality characteristics and age-32 oral health in a prospective study of a complete birth cohort born in Dunedin, New Zealand. Personality was measured using the Multidimensional Personality Questionnaire (MPQ). Oral health was measured using the short-form Oral Health Impact Profile (OHIP-14), a global measure, and dental examinations. Personality profiles were constructed for 916 individuals (50.8% men) using standardized MPQ scores, and multivariate analyses examined their association with oral health. Those reporting 1+ OHIP-14 impacts had higher Negative Emotionality scores (and lower Constraint and Positive Emotionality MPQ superfactor scores) than those who did not. After controlling for gender, clinical status, and the other two MPQ superfactors, those scoring higher on Negative Emotionality had a greater risk of reporting 1+ OHIP-14 impacts, as well as 3+ OHIP-14 impacts and worse-than-average oral health. They also had a greater risk of having lost at least one tooth from caries and of having 3+ decayed surfaces. Personality characteristics appear to shape self-reports of oral health. Personality is also a risk factor for clinical disease status, at least with respect to dental caries and its sequelae. Because the attitudes and values tapped into by personality tests can be altered by brief cognitive interventions, those might be useful in preventive dentistry. PMID:21896053

The author warns that a great increase is expected in the number of dementia patients in the United Kingdom and he argues that care for these patients be given a high place on the national agenda. Dementia was also a major issue at the meeting of the International Association for Dental Research in March 2007. Several international studies presented there indicated that elderly people with dementia constitute a group at risk with respect to oral health. In the evaluation of the editorial, the situation in The Netherlands is described. There is also serious concern in The Netherlands about the statistics with respect to dementia. Due to the growing number of frail elderly people having a natural dentition, the need for professional oral care will increase. General practitioners have the important task of providing adequate oral health care for elderly people suffering from dementia who are still living at home. Guidelines for Oral Care, having to do with the improvement of oral care in institutions, appeared recently. With the guidelines, a good basis for developing adequate oral health care of frail elderly people is available. However, the implementation of these guidelines will require some attention.

  17. Aerodigestive cancers: oral cancer.

    PubMed

    Haws, Luke; Haws, Bryn Taylor

    2014-09-01

    Worldwide, approximately 260,000 new cases of oral cancer occur, and more than 125,000 mortalities are attributed to oral cancers each year. Oral cancers most commonly arise in the tongue, followed by the floor of the mouth and the lower gum. Tobacco and alcohol use are the major risk factors, although human papillomavirus has been identified as an etiology in a small percentage of oral squamous cell cancers. Although the evidence to support routine annual screening for oral cancers is inconclusive, family physicians and dental practitioners should be attentive to precursor lesions, such as leukoplakia and erythroplakia, and strongly consider obtaining or referring for biopsy patients with suspicious lesions. Depending on stage, management of oral cancers often involves surgery, with or without postoperative radiotherapy or chemotherapy. Patients who have been treated for these cancers should undergo close surveillance by otolaryngology subspecialists, but their family physicians primarily will be responsible for their long-term care. Complications relating to management, including difficulties with speech, swallowing, and chewing, will need to be addressed. For patients with advanced-stage disease, family physicians also may be responsible for palliative and end-of-life care. PMID:25198382

  18. Oral and systemic photoprotection.

    Chen, Andrew C; Damian, Diona L; Halliday, Gary M

    Photoprotection can be provided not only by ultraviolet (UV) blockers but also by oral substances. Epidemiologically identified associations between foods and skin cancer and interventional experiments have discovered mechanisms of UV skin damage. These approaches have identified oral substances that are photoprotective in humans. UV inhibits adenosine triphosphate (ATP) production causing an energy crisis, which prevents optimal skin immunity and DNA repair. Enhancing ATP production with oral nicotinamide protects from UV immunosuppression, enhances DNA repair and reduces skin cancer in humans. Reactive oxygen species also contribute to photodamage. Nontoxic substances consumed in the diet, or available as oral supplements, can protect the skin by multiple potential mechanisms. These substances include polyphenols in fruit, vegetables, wine, tea and caffeine-containing foods. UV-induced prostaglandin E2 (PGE2 ) contributes to photodamage. Nonsteroidal anti-inflammatory drugs and food substances reduce production of this lipid mediator. Fish oils are photoprotective, at least partially by reducing PGE2 . Orally consumed substances, either in the diet or as supplements, can influence cutaneous responses to UV. A current research goal is to develop an oral supplement that could be used in conjunction with other sun protective strategies in order to provide improved protection from sunlight. PMID:24313740

  19. Melatonin and Oral Cavity

    2012-01-01

    While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this paper focuses on the involvement of melatonin in oxidative stress diseases of oral cavity as well as on potential therapeutic implications of melatonin in dental disorders. Melatonin has immunomodulatory and antioxidant activities, stimulates the proliferation of collagen and osseous tissue, and acts as a protector against cellular degeneration associated with aging and toxin exposure. Arising out of its antioxidant actions, melatonin protects against inflammatory processes and cellular damage caused by the toxic derivates of oxygen. As a result of these actions, melatonin may be useful as a coadjuvant in the treatment of certain conditions of the oral cavity. However, the most important effect of melatonin seems to result from its potent antioxidant, immunomodulatory, protective, and anticancer properties. Thus, melatonin could be used therapeutically for instance, locally, in the oral cavity damage of mechanical, bacterial, fungal, or viral origin, in postsurgical wounds caused by tooth extractions and other oral surgeries. Additionally, it can help bone formation in various autoimmunological disorders such as Sjorgen syndrome, in periodontal diseases, in toxic effects of dental materials, in dental implants, and in oral cancers.

    Determining the bacterial composition of the canine oral microbiome is of interest for two primary reasons. First, while the human oral microbiome has been well studied using molecular techniques, the oral microbiomes of other mammals have not been studied in equal depth using culture independent methods. This study allows a comparison of the number of bacterial taxa, based on 16S rRNA-gene sequence comparison, shared between humans and dogs, two divergent mammalian species. Second, canine oral bacteria are of interest to veterinary and human medical communities for understanding their roles in health and infectious diseases. The bacteria involved are mostly unnamed and not linked by 16S rRNA-gene sequence identity to a taxonomic scheme. This manuscript describes the analysis of 5,958 16S rRNA-gene sequences from 65 clone libraries. Full length 16S rRNA reference sequences have been obtained for 353 canine bacterial taxa, which were placed in 14 bacterial phyla, 23 classes, 37 orders, 66 families, and 148 genera. Eighty percent of the taxa are currently unnamed. The bacterial taxa identified in dogs are markedly different from those of humans with only 16.4% of oral taxa are shared between dogs and humans based on a 98.5% 16S rRNA sequence similarity cutoff. This indicates that there is a large divergence in the bacteria comprising the oral microbiomes of divergent mammalian species. The historic practice of identifying animal associated bacteria based on phenotypic similarities to human bacteria is generally invalid. This report describes the diversity of the canine oral microbiome and provides a provisional 16S rRNA based taxonomic scheme for naming and identifying unnamed canine bacterial taxa. PMID:22558330

  1. Oral Insulin Reloaded

    2014-01-01

    Optimal coverage of insulin needs is the paramount aim of insulin replacement therapy in patients with diabetes mellitus. To apply insulin without breaking the skin barrier by a needle and/or to allow a more physiological provision of insulin are the main reasons triggering the continuous search for alternative routes of insulin administration. Despite numerous attempts over the past 9 decades to develop an insulin pill, no insulin for oral dosing is commercially available. By way of a structured approach, we aim to provide a systematic update on the most recent developments toward an orally available insulin formulation with a clear focus on data from clinical-experimental and clinical studies. Thirteen companies that claim to be working on oral insulin formulations were identified. However, only 6 of these companies published new clinical trial results within the past 5 years. Interestingly, these clinical data reports make up a mere 4% of the considerably high total number of publications on the development of oral insulin formulations within this time period. While this picture clearly reflects the rising research interest in orally bioavailable insulin formulations, it also highlights the fact that the lion’s share of research efforts is still allocated to the preclinical stages.

    Oral health care in pregnancy is often avoided and misunderstood by physicians, dentists, and patients. Evidence-based practice guidelines are still being developed. Research suggests that some prenatal oral conditions may have adverse consequences for the child. Periodontitis is associated with preterm birth and low birth weight, and high levels of cariogenic bacteria in mothers can lead to increased dental caries in the infant. Other oral lesions, such as gingivitis and pregnancy tumors, are benign and require only reassurance and monitoring. Every pregnant woman should be screened for oral risks, counseled on proper oral hygiene, and referred for dental treatment when necessary. Dental procedures such as diagnostic radiography, periodontal treatment, restorations, and extractions are safe and are best performed during the second trimester. Xylitol and chlorhexidine may be used as adjuvant therapy for high-risk mothers in the early postpartum period to reduce transmission of cariogenic bacteria to their infants. Appropriate dental care and prevention during pregnancy may reduce poor prenatal outcomes and decrease infant caries. PMID:18481562

  3. The Oral Microbiota.

    Arweiler, Nicole B; Netuschil, Lutz

    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.

    Divers can have several oral problems. Firstly, problems caused by pressure changes. These are barodontalgia and odontocrexis. Barodontalgia is toothache by barotrauma. Odontocrexis is restorations coming lose or breaking or tooth fractures by expansion of air beneath restorations. Other problems can occur by cements used to fix casted restorations, by inflammations in the orofacial region, and by not yet fully healed oral wounds. Secondly, there are problems related to the diver's mouthpiece. To keep the mouthpiece in place, the mandible has to be forced in a forward position. Holding this position often and for long periods of time, may develop or aggravate temporomandibular dysfunction. Insufficient fit of the mouthpiece may induce oral mucosal lesions. Therefore, it is recommended to produce individual diver mouthpieces. It is also recommended to produce individual diver mouthpieces for complete dentures wearing divers and for divers with fixed orthodontic appliances. PMID:15932043

    2012-11-01

    The terms Oral cancer (OC) and oral squamous cell carcinoma (OSCC) are used interchangeably, as more than 95% of all OCs are OSCCs. Worldwide up to 275 000 new cases of OC are seen every year. Most of these cases are seen in developing countries such as South Africa. Up to 50% of all patients living with OC will die within five years, and this survival rate has not improved over the last few decades. Tobacco and alcohol usage account for up to 75% of all OC cases. As these causative factors can be avoided, all oral health workers should be aware of the aetiology of OC so that sound preventive advice may be given to their patients. Infections and nutrition play a lesser but still important role in the aetiology of OC. This article reviews the importance of the aetiology of OC, with the emphasis on tobacco and alcohol.

  6. Nasal vs oral intubation.

    PubMed

    Holzapfel, L

    2003-05-01

    Both nasal and oral route for intubation have advantages and disadvantages. Oral intubation is easier to perform, faster and less painful than nasal intubation under direct laryngoscopy, while blind nasal intubation represents a good alternative in conscious patient, without sedation. In trauma patient, oral route should be preferred, with cervical immobilisation. By the contrary, nasal intubation can cause bleeding, retro-pharyngeal and turbinate bones injury, but it seems preferable in preventing laryngeal complications. Moreover nasal intubation seem to increase risk for sinusitis while, there is no clear advantage for any of the two routes, concerning nosocomial pneumonia, bacteriemia and otitis. Nevertheless nasal route increases comfort for the patient and decreases injury and necrosis of tongue and lips; tube fastening is simpler thus reducing accidental extubation. PMID:12768165

    Direct endoscopic views of bile duct have been described in literature since the 1970s. Since then rapid strides have been made with the advent of technologically advanced systems with better image quality and maneuverability. The single operator semi-disposable per-oral cholangioscope and other novel methods such as the cholangioscopy access balloon are likely to revolutionize this field. Even though cholangioscopy is currently used primarily for characterization of indeterminate strictures and management of large bile duct stones, the diagnostic and therapeutic indications are likely to expand in future. The following is an overview of the currently available per-oral cholangioscopy equipments, indications for use and future directions. PMID:21776429

    Accurate diagnosis of acute oral ulcers can be challenging. Important historic details include the pattern of recurrence, anatomic areas of involvement within the mouth and elsewhere on the mucocutaneous surface, associated medical symptoms or comorbidities, and symptomology. Careful mucocutaneous examination is essential. When necessary, biopsy at an active site without ulceration is generally optimal. Depending on the clinical scenario, supplemental studies that may be useful include cultures; perilesional biopsy for direct immunofluorescence testing; and evaluation for infectious diseases, gluten sensitivity, inflammatory bowel disease, human immunodeficiency virus infection, connective tissue diseases, or hematinic deficiencies. Clinicians should maintain a broad differential diagnosis when evaluating patients with acute oral ulcers. PMID:27343961

    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.

    Background: The objective of this article is to summarize the published literature concerning the pharmacokinetics and pharmacodynamics of oral anticoagulant drugs that are currently available for clinical use and other aspects related to their management. Methods: We carried out a standard review of published articles focusing on the laboratory and clinical characteristics of the vitamin K antagonists; the direct thrombin inhibitor, dabigatran etexilate; and the direct factor Xa inhibitor, rivaroxaban Results: The antithrombotic effect of each oral anticoagulant drug, the interactions, and the monitoring of anticoagulation intensity are described in detail and discussed without providing specific recommendations. Moreover, we describe and discuss the clinical applications and optimal dosages of oral anticoagulant therapies, practical issues related to their initiation and monitoring, adverse events such as bleeding and other potential side effects, and available strategies for reversal. Conclusions: There is a large amount of evidence on laboratory and clinical characteristics of vitamin K antagonists. A growing body of evidence is becoming available on the first new oral anticoagulant drugs available for clinical use, dabigatran and rivaroxaban. PMID:22315269

    Dhont, Marc

    2010-12-01

    On the 50th birthday of the pill, it is appropriate to recall the milestones which have led to its development and evolution during the last five decades. The main contraceptive effect of the pill being inhibition of ovulation, it may be called a small miracle that this drug was developed long before the complex regulation of ovulation and the menstrual cycle was elucidated. Another stumbling block on its way was the hostile climate with regard to contraception that prevailed at the time. Animal experiments on the effect of sex steroids on ovulation, and the synthesis of sex steroids and orally active analogues were the necessary preliminaries. We owe the development of oral contraceptives to a handful of persons: two determined feminists, Margaret Sanger and Katherine McCormick; a biologist, Gregory Pincus; and a gynaecologist, John Rock. Soon after the introduction of the first pills, some nasty and life-threatening side effects emerged, which were due to the high doses of sex steroids. This led to the development of new preparations with reduced oestrogen content, progestins with more specific action, and alternative administration routes. Almost every decade we have witnessed a breakthrough in oral contraception. Social and moral objections to birth control have gradually disappeared and, notwithstanding some pill scares, oral contraceptives are now one of the most used methods of contraception. Finally, all's well that ends well: recent reports have substantiated the multiple noncontraceptive health benefits paving the way for a bright future for this 50-year-old product. PMID:21091163

Led by the AAS Historical Astronomy Division (HAD) and partially funded by the American Institute of Physics Niels Bohr Library and ongoing support from the AAS, volunteers have collected oral histories from astronomers at professional meetings starting in 2015, including AAS, DPS, and the IAU general assembly. Each interview lasts one and a half to two hours and focuses on interviewees’ personal and professional lives. Questions include those about one’s family, childhood, strong influences on one’s scientific career, career path, successes and challenges, perspectives on how astronomy is changing as a field, and advice to the next generation. Each interview is audio recorded and transcribed, the content of which is checked with each interviewee. Once complete, interview transcripts are posted online as part of a larger oral history library at https://www.aip.org/history-programs/niels-bohr-library/oral-histories. Future analysis will reveal a rich story of astronomers and will help the community address issues of diversity, controversies, and the changing landscape of science. We are still recruiting individuals to be interviewed from all stages of career from undergraduate students to retired and emeritus astronomers. Contact Jarita Holbrook to schedule an interview or to find out more information about the project (astroholbrook@gmail.com).

    Oral cavity squamous cell cancers form a significant percentage of the cancers seen in India. While clinical examination allows direct visualization, it cannot evaluate deep extension of disease. Cross-sectional imaging has become the cornerstone in the pretreatment evaluation of these cancers and provides accurate information about the extent and depth of disease that can help decide the appropriate management strategy and indicate prognosis. Early cancers are treated with a single modality, either surgery or radiotherapy while advanced cancers are offered a combination of surgery, radiotherapy and chemotherapy. Imaging can decide resectability, help plan the precise extent of resection, and indicate whether organ conservation therapy should be offered. Quality of life issues necessitate preservation of form and function and pretreatment imaging helps plan appropriate reconstruction and counsel patients regarding lifestyle changes. Oral cavity has several subsites and the focus of the review is squamous cancers of the gingivobuccal region, oral tongue and retromolar trigone as these are most frequently encountered in the subcontinent. References for this review were identified by searching Medline and PubMed databases. Only articles published in English language literature were selected. This review aims to familiarize the radiologist with the relevant anatomy of the oral cavity, discuss the specific issues that influence prognosis and management at the above subsites, the optimal imaging methods, the role of imaging in accurately staging these cancers and in influencing management. A checklist for reporting will emphasize the information to be conveyed by the radiologist. PMID:23599568

    Probiotics are living microorganisms (e.g., bacteria) that are either the same as or similar to organisms found naturally in the human body and may be beneficial to health. Current researches have shown that the balance between beneficial and pathogenic bacteria is essential in order to maintain the oral health. Therefore, oral cavity has recently been suggested as a relevant target for probiotic applications. Dental caries can be seen as a microbial imbalance where the oral microbiota shift towards community dominance which produces acidogenic and acid-tolerant gram positive bacteria. Similarly, the accumulation of bacteria within the biofilm, facilitated by poor oral hygiene, predisposes to allogenic shifts in the microbial community, leading to the onset of periodontal inflammation. Probiotic bacteria belonging to the genus of Lactobacillus, Bifidobacterium and Streptococcus have been proven effective for preventing caries by reducing the number of cariogenic bacteria in saliva after a short period of consuming the probiotic. In contrast, the effect of probiotics on improving gingivitis and periodontitis has been less investigated. The currently available studies on the effect of probiotics on periodontal pathogens and clinical periodontal parameters showed differing results depending on the strains used and the endpoints analyzed. Many of the clinical studies are pilot in nature and with low quality, therefore, properly conducted clinical trials, using probiotic strains with in vitro proven periodontal probiotic effects, are needed. The putative beneficial effects of probiotics on oral malodour have also been evaluated, but further evidence is needed to fully explore the potential of probiotics for preventing malodour.

This practice has a long history as part of religious, tribal, cultural or sexual symbolism. This article reviews current knowledge on injuries or diseases that might be produced by piercing in the oral cavity. We propose a classification to diagnosed the pathologies related to oral an perioral piercing Methods. A search was conducted of articles in PubMed, Scielo published between 1997 and 2007, using the key words ``oral and perioral, piercing ´´, ``oral, piercing and disease”, ``recessions and oral piercing´´. It has reviewed about twentythree articles 17 were narrative reviews and 6 case series Results. A review was carried out on the origins of oral and perioral body piercing and its local implications, classifying the different alterations like recessions, systemic implications that it can produce in the oral and perioral cavity. Conclusion. Patients with oral and perioral piercing should be regularly followed up because of the possible development of different types of adverse effects. Clinical implications. Adverse effects of oral and perioral piercing can be systemic, with transmission of infectious diseases such as hepatitis B or C, or can be local, with alteration of oral mucosae or even of dental structures.

    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

    Objectives The objective of this study was to identify salivary and serum concentrations of interleukin (IL)-8, IL-6, and tumor necrosis factor alpha (TNF-α) in patients with oral lichen planus, oral leukoplakia, oral submucous fibrosis, and healthy controls. Materials and Methods Patients selected included 54 oral lichen planus (41 to 65 years), 50 oral leukoplakia (42 to 65 years), 51 oral submucous fibrosis (41 to 65 years), and 50 healthy controls (42 to 65 years). Oral lichen planus, oral leukoplakia, and oral submucous fibrosis cases were diagnosed using histopathological analysis. Salivary and serum cytokine concentrations were measured using enzyme-linked immunoassay kits in all subjects. Results The levels of serum and salivary TNF-α, IL-6, and IL-8 were statistically significantly increased in oral leukoplakia, submucous fibrosis, and lichen planus in contrast to normal healthy subjects (P<0.05). Serum and salivary correlation analysis revealed strong and highly significant correlations for TNF-α, IL-6, and IL-8 in all groups (r=0.72-0.82, P<0.05). Conclusion Salivary and serum cytokines were also elevated when analyzed in oral precancerous lesions. Thus, salivary and serum IL-8, IL-6, and TNF-α levels might act as diagnostic markers for detection of oral precancer. PMID:26339574

    Oral cancer is a serious disease that is on the increase. The most pressing need is early recognition and referral for specialist treatment. Too many cases present with advanced tumours. Radiotherapy and surgery remain the primary modalities of curative treatment, but understanding of tumour pathology and developments in surgical and radiotherapeutic technique have combined to produce a rational approach to management. In many instances 'radical' methods of surgical access can be combined with a more 'conservative' resection of the mandible or cervical lymph nodes. One-stage reconstructive procedures, often incorporating osteotomy techniques, miniature bone plating and free tissue transfer, have minimised the morbidity and functional deficit so often seen after earlier operations. All surgeons involved in the modern management of oral cancer should have expertise in these techniques or be part of a team which can provide them. PMID:8540656

    Lichen planus is an inflammatory mucocutaneous disease that can affect the skin, hair, nails, and mucosal surfaces. Mucosal sites of involvement include oral, genital, ocular, otic, esophageal, and, less commonly, bladder, nasal, laryngeal, and anal surfaces. Oral lichen planus is a mucosal variant of lichen planus, which tends to affect women more often than men, with a typically more chronic course and potential for significant morbidity. Treatment can be challenging, and there is potentially a low risk of malignant transformation; however, therapeutic benefits can be obtained with various topical and systemic medications. Clinical monitoring is recommended to ensure symptomatic control. Increasing awareness and recognition of this entity have continued to fuel advances in therapy and in our understanding of the disease. PMID:27343965

    Although their first application in clinical practice occurred in the 1940s, vitamin K antagonists remain the only form of oral anticoagulant medication approved for long-term use. Although the available vitamin K antagonists are highly effective for the prevention and/or treatment of most thrombotic disease, the significant interpatient and intrapatient variability in dose-response, the narrow therapeutic index, and the numerous drug and dietary interactions associated with these agents have led clinicians, patients, and investigators to search for alternative agents. Three new orally administered anticoagulants (apixaban, dabigatran, and rivaroxaban) are in the late stages of development and several others are just entering (or moving through) earlier phases of investigation. These novel anticoagulant medications are being studied for the prevention and treatment of venous thromboembolism, the treatment of acute coronary syndromes and the prevention of stroke in patients with atrial fibrillation. This review summarizes published clinical trial data pertinent to apixaban, dabigatran, and rivaroxaban. PMID:19880491

    Immune mediated diseases of oral cavity are uncommon. The lesions may be self-limiting and undergo remission spontaneously. Among the immune mediated oral lesions the most important are lichen planus, pemphigus, erythema multiformi, epidermolysis bullosa, systemic lupus erythematosis. Cellular and humoral mediated immunity play a major role directed against epithelial and connective tissue in chronic and recurrent patterns. Confirmatory diagnosis can be made by biopsy, direct and indirect immunoflouresence, immune precipitation and immunoblotting. Therapeutic agents should be selected after thorough evaluation of immune status through a variety of tests and after determining any aggravating or provoking factors. Early and appropriate diagnosis is important for proper treatment planning contributing to better prognosis and better quality of life of patient. PMID:26015713

    Evaluation of Skylab crewmembers for mission related effects on oral health in relation to possible dental injuries provided the following distinctive changes: (1) increased counts of specific anaerobic and streptococcal components; (2) elevations in levels of secretory IgA concurrent with diminutions of salivary lysozyme; and (3) increases in dental calculus and gingival inflammations. The clinical changes are considered to be more influenced by the preexisting state of dental health than by any mission related effects.

    The discovery during the first half of the 20th century of the link between natural fluoride, adjusted fluoride levels in drinking water and reduced dental caries prevalence proved to be a stimulus for worldwide on-going research into the role of fluoride in improving oral health. Epidemiological studies of fluoridation programmes have confirmed their safety and their effectiveness in controlling dental caries. Major advances in our knowledge of how fluoride impacts the caries process have led to the development, assessment of effectiveness and promotion of other fluoride vehicles including salt, milk, tablets, toothpaste, gels and varnishes. In 1993, the World Health Organization convened an Expert Committee to provide authoritative information on the role of fluorides in the promotion of oral health throughout the world (WHO TRS 846, 1994). This present publication is a revision of the original 1994 document, again using the expertise of researchers from the extensive fields of knowledge required to successfully implement complex interventions such as the use of fluorides to improve dental and oral health. Financial support for research into the development of these new fluoride strategies has come from many sources including government health departments as well as international and national grant agencies. In addition, the unique role which industry has played in the development, formulation, assessment of effectiveness and promotion of the various fluoride vehicles and strategies is noteworthy. This updated version of 'Fluoride and Oral Health' has adopted an evidence-based approach to its commentary on the different fluoride vehicles and strategies and also to its recommendations. In this regard, full account is taken of the many recent systematic reviews published in peer reviewed literature. PMID:27352462

  2. Antibiotics and oral contraceptives.

    Dermatologists often prescribe oral tetracycline for the control of acne, primarily, and to a much lesser extent, for the treatment of cutaneous infections. A number of the patients taking tetracycline are also taking birth control pills. A recent article in the British Medical Journal (1980;1:293) indicates that this combination can lead to a failure of the (OC) oral contraceptive. Such failure had been associated with ampicillin as well. It is believed that the mechanism for this was the disturbance in normal gut flora, with consequent effects on bacterial hydrolysis of steroid conjugates. This would interrupt the enterohepatic circulation of contraceptive steroids, resulting in a less than normal concentration of circulating steroids. It was recommended that women taking low-dose OCs take extra precautions against pregnancy during any cycle in which antibiotics are given. In regard to our care of and responsibilities to our patients, and in an era when malpractice suits for all types of reasons are more common, it certainly behooves dermatologists to recognize and be concerned about this potential consequence of prescribing oral antibiotics.

    Oral health includes freedom from disease in the gums, the mucosa and the teeth. There has been a striking reduction in dental caries and periodontitis in industrialized countries, although the proportion with severe disease has remained at 10-15%, and the prevalence increases in less developed countries. If left untreated, these diseases may lead to pain, and impaired quality of life and nutritional status. Prevention and treatment need, besides traditional implementation of proper oral hygiene, sugar restriction and use of fluoride, newer cost-effective strategies. Non-sweetened dairy products, which are proven non-cariogenic, or specific bioactive components from alike sources might prove to be part of such strategies. Thus, milk proteins, such as bovine and human caseins and lactoferrin, inhibit initial attachment of cariogenic mutans streptococci to hydroxyapatite coated with saliva or purified saliva host ligands. In contrast, both bovine and human milk coated on hydroxyapatite promotes attachment of commensal Actinomyces naeslundii and other streptococci in vitro, and phosphorylated milk-derived peptides promote maintenance of tooth minerals, as shown for the β-casein-derived caseino-phosphate peptide. Observational studies are promising, but randomized clinical trials are needed to reveal if dairy products could be a complementary treatment for oral health. PMID:21335990

    Abstract Background: We aimed to study the prevalence of oral sex and its possible association with human papillomavirus (HPV) 16 infection in the development of oropharyngeal cancer in the US population for possible prevention. Methods: We conduct a systemic review on the prevalence of oral sex among Americans among different age groups, the prevalence of HPV 16 infection reported in oropharyngeal cancer, and correlation between oral sex and oropharyngeal cancer. Results: Oral sex is prevalent among adolescents and sexually active adults. Sixty percent of oropharyngeal cancer reported in the United States is associated with HPV 16 infections. Individuals who practiced oral sex with multiple partners are at risk for developing oropharyngeal cancer and need to be informed about practicing safe sex or getting vaccination. Conclusion: Family physicians will play a key role in prevention and educating the public about the risk of oral sex. PMID:27428229

    Organ transplantation is a widely undertaken procedure and has become an important alternative for the treatment of different end-stage organ diseases that previously had a poor prognosis. The field of organ transplant and hematopoietic stem cell transplant is developing rapidly. The increase in the number of transplant recipients also has an impact on oral and dental services. Most of the oral problems develop as a direct consequence of drug-induced immunosuppression or the procedure itself. These patients may present with oral complaints due to infections or mucosal lesions. Such lesions should be identified, diagnosed, and treated. New treatment strategies permit continuous adaptation of oral care regimens to the changing scope of oral complications. The aim of this review is to analyze those oral manifestations and to discuss the related literature. PMID:26005458

    Lymphoproliferative disorders are heterogeneous malignancy characterized by the expansion of a lymphoid clone more or less differentiated. At the level of the oral cavity, the lymphoproliferative disorder can occur in various ways, most commonly as lymphoid lesions with extranodal externalization, but sometimes, oral lesions may represent a localization of a disease spread. With regard to the primary localizations of lymphoproliferative disorders, a careful examination of the head and neck, oral, and oropharyngeal area is necessary in order to identify suspicious lesions, and their early detection results in a better prognosis for the patient. Numerous complications have been described and frequently found at oral level, due to pathology or different therapeutic strategies. These complications require precise diagnosis and measures to oral health care. In all this, oral pathologists, as well as dental practitioners, have a central role in the treatment and long-term monitoring of these patients. PMID:20871659

    Oral and oropharyngeal cancer (OPC) is a complex and often relentless malignancy prone to local invasion and dissemination. Despite advances in understanding of the disease and improved therapeutic interventions, it continues to be diagnosed at an advanced stage and the survival rate remains poor. The financial cost of treating OPC may be the highest of all cancers in the United States and survivors often experience major detriments to quality of life. Major risk factors for OPC are tobacco, alcohol, areca nut, and human papillomavirus infection. This article updates medical practitioners on the causes, presentation, diagnosis, and management of OPC. PMID:25443678

    Ionizing radiation used in treating the head and neck area produces oral side effects such as mucositis, salivary changes, trismus and radiation caries. Sequelae of cancer chemotherapy often include oral stomatitis, myelosuppression and immunosuppression. Infections of dental origin in compromised patients are potentially lethal. Specific programs to eliminate dental pathology before radiation and chemotherapy, and to maintain oral hygiene during and after therapy, will minimize these complications.

    Management of oral biofilms allows dentists to help control the pathogens responsible for periodontal disease and decay. Increasing evidence indicates that the oral system is a portal for pathogenic microorganisms. This is a cumulative situation with systemic effects that can overcome an individual's resistance threshold, culminating in systemic sequela. New evidence indicates that controlling these oral pathogens has systemic benefits, as oral pathology is related to cardiovascular and respiratory disease, diabetes, and systemic inflammatory responses, as well as low birth weight and pre-term deliveries. Some insurance companies now cover periodontal scaling for gingivitis and periodontal disease for pregnant women and patients at risk for pregnancy. PMID:17511362

Ninety percent of patients suffering from halitosis have oral causes, such as poor oral hygiene, periodontal disease, tongue coat, food impaction, unclean dentures, faulty restorations, oral carcinomas, and throat infections. The remaining 10 percent of halitosis sufferers have systemic causes that include renal or hepatic failure, carcinomas, diabetes or trimethylaminuria.

Oral mucosal and salivary gland manifestations include several that were not seen before the AIDS epidemic, while others are more severe in this population. Oral lesions reflect HIV status and the stage of immunosuppression, are important elements in HIV staging and classification schemes, raise pertinent questions about mucosal aspect of immunosuppression, and provide therapeutic challenges. Their pervasive nature and biological significance emphasise the importance of a careful oral examination as part of the general clinical evaluation. PMID:8806295

    Aim The aim of this study was to determine whether oral, tactile/kinaesthetic (T/K), or combined (oral + T/K) interventions enhance oral feeding performance and whether combined (oral + T/K) interventions have an additive/synergistic effect. Method Seventy-five preterm infants (mean gestational age 29wk; standard error of the mean [SEM] 0.3wk; mean birthweight 1340.3g; SEM 52.5g; 49 males and 26 females) were randomly assigned to one of three intervention groups or a control group. The oral group received sensorimotor input to the oral structures, the T/K group received sensorimotor input to the trunk and limbs, and the combined (oral + T/K) group received both. The outcomes were time from introduction of nipple feeding to independent oral feeding (days), proficiency (intake in the first 5min, %), volume transfer (%), rate of transfer (ml/min), volume loss (%), and length of hospital stay (days). Results Infants in the three intervention groups achieved independent oral feeding 9 to 10 days earlier than those in the control group (p<0.001; effect size 1.9–2.1). Proficiency (p≤0.002; effect size 0.7–1.4) at the time of one to two and three to five oral feedings per day, volume transfer (p≤0.001; effect size 0.8–1.1) at one to two, three to five, and six to eight oral feedings per day, and overall rate of transfer (p≤0.018; effect size 0.8–1.1) were greater, and overall volume losses were less (p≤0.007; effect size 0.9–1.1), than in the control group (p≤0.042). The combined (oral + T/K) group attained independent oral feeding at a significantly younger postmenstrual age than controls (p=0.020) and had clinically greater proficiency than the T/K group (p=0.020; effect size 0.7) and oral group (p=0.109; effect size 0.5). Length of hospital stay was not significantly different between groups (p=0.792; effect size 0.02–0.3).

    Oral jewelry is popular. One of the most widely spread types are so-called tooth diamonds made of composite materials which are applied to the teeth with an adhesive. Note that parents are required to sign a release form for under-aged patients in Switzerland. Tooth cap grills and gold teeth are considered status symbols within the Hip-Hop fashion scene. However, tooth ornaments favour the accumulation of plaque and can diminish the ability to articulate. With respect to jewelry in oral soft tissue especially tongue and lip piercings are of significance to dentists. Besides the systemic complications, which are mostly caused by a lack of hygiene or the failure of noting medical contraindications by the piercer, local complications occur frequently. After surgery, pain, swelling, infections as well as hemorrhages or hematomas can be observed. Long-term effects can be problematic: gingival recession can be discernes mainly in the case of lip piercings the loss of hard tooth substance in the case of tongue piercings. Because of that, conservation therapies can become indespensable. Patients wearing dental jewelry have to be aware of risks of tooth damage, and they regularly have to undergo dental check-ups. Information campaigns--for dentists as well as patients--are necessary. PMID:20112640

  16. Pharmacogenetics of oral anticoagulants.

    PubMed

    Daly, Ann K; King, Barry P

    2003-05-01

    There is wide interindividual variation in oral anticoagulant dose requirement, which is partly genetically determined. Several cytochrome P450s contribute to oxidative metabolism of oral anticoagulants. The most important of these is CYP2C9, which hydroxylates the S-enantiomers of warfarin, acenocoumarol and phenprocoumon with high catalytic activity. In at least eight separate clinical studies, possession of the CYP2C9*2 or CYP2C9*3 variant alleles, which result in decreased enzyme activity, has been associated with a significant decrease in a mean warfarin dose requirement. Several studies also suggest that possession of a CYP2C9 variant allele is associated with an increased risk of adverse events, such as bleeding. Possession of the CYP2C9*3 variant also appears to be associated with a low acenocoumarol dose requirement. Other genetic factors, such as polymorphisms in the cytochromes P450 that metabolize the R-enantiomers of warfarin and acenocoumarol, may also be relevant to anticoagulant dose. The molecular basis of anticoagulant resistance where a higher than normal dose of anticoagulant is required remains unclear, but could be due to unusually high CYP2C9 activity (pharmacokinetic resistance) or to an abnormality in the target enzyme vitamin K epoxide reductase (pharmacodynamic resistance).

    Background Thrombotic disorders remain a leading cause of death in the Western world, and in this regard a number of anticoagulation treatment have been used, including heparins, fondaparinux, vitamin K antagonists (warfarin, acenocoumarol), and new oral anticoagulants such as apixaban. For years there has been great controversy regarding the use of anticoagulants in planning dental treatments that imply bleeding. The main concerns about using new oral anticoagulants in invasive dental procedures are bleeding due to the lack of an antidote, and the thrombotic risk of the disease for which anticoagulation was indicated in the first place. Material and Methods A literature search was conducted through May 2014 using the keyword “apixaban” for publications in the ISI Web of Knowledge. The search was extended to other databases (PubMed, Scopus and the Cochrane Library). Results Based on the results of the different studies, apixaban seems to be a good alternative to conventional anticoagulation and a reasonable treatment option, though its main and most common adverse effect is bleeding. Dose adjustment is needed in some patients, though regular laboratory monitoring is not required. The use of the drug in different patient populations will define its final indications and doses. Conclusions Regarding the use of apixaban in the dental setting, there is a compelling need for further clinical studies in order to establish more evidence-based guidelines for patients requiring antithrombotic treatment. Key words:Apixaban, dental treatment, dental implications. PMID:26535102

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.

    Lichen planus is an immunologically mediated mucocutaneous disease that is triggered by varied etiological agents. The oral lichenoid reaction is considered a variant of the disease that needs to be clearly diagnosed as a separate entity from oral lichen planus and treated. They follow a strict cause-effector relationship, protocols that suggest the differentiation. Lichen planus has varied clinical forms in the oral mucosa and cutaneously that has different prognosis. This condition also arises in association with various other systemic conditions such as hypertension, diabetes mellitus. There have been cases reported in the esophagus, larynx, scalp, nail, cutaneous areas, especially arms and wrists, trunk. There is reported malignant transformation that essentiates careful examination, treatment protocol and regular follow-up sessions. This article throws light on the disease condition of oral lichen planus and oral lichenoid reaction that is essential for the differentiation and treatment. PMID:26015696

    2013-01-01

    Background: Submental flap is a useful technique for reconstruction of medium to large oral cavity defects. Hair bearing nature of this flap in men makes it less appropriate. Therefore, deepithelialized variant is introduced to overcome the problem of hair with this flap. Recently, application of this flap has been introduced in maxillofacial trauma patients. Materials and Methods: Deepithelialized orthograde submental flap is used for the reconstruction of oral cavity mucosal defects. Results: Four cases including two trauma patients and two squamous cell carcinomas (SCCs) of oral cavity were treated using deepithelialized orthograde submental flap. There were no complications in all four patients and secondary epithelialization occurred in raw surface of the flap which was exposed to oral cavity. Conclusion: Deepithelialized orthograde submental flap is very effective in reconstruction of oral cavity in men. The problem of hair is readily solved using this technique without jeopardizing flap blood supply. PMID:24205473

    Organisms residing in the oral cavity (oral microbiota) contribute to health and disease, and influence diseases like gingivitis, periodontitis, and oral candidiasis (the most common oral complication of HIV-infection). These organisms are also associated with cancer and other systemic diseases including upper respiratory infections. There is limited knowledge regarding how oral microbes interact together and influence the host immune system. Characterizing the oral microbial community (oral microbiota) in health and disease represents a critical step in gaining insight into various members of this community. While most of the studies characterizing oral microbiota have focused on bacterial community, there are few encouraging studies characterizing the oral mycobiome (the fungal component of the oral microbiota). Our group recently characterized the oral mycobiome in health and disease focusing on HIV. In this chapter we will describe the methods used by our group for characterization of the oral mycobiome.

    The prevalence of prosthodontic treatment has been well recognized, and the need is continuously increasing with the ageing population. While the oral mucosa plays a critical role in the treatment outcome, the associated biomechanics is not yet fully understood. Using the literature available, this paper provides a critical review on four aspects of mucosal biomechanics, including static, dynamic, volumetric and interactive responses, which are interpreted by its elasticity, viscosity/permeability, apparent Poisson's ratio and friction coefficient, respectively. Both empirical studies and numerical models are analysed and compared to gain anatomical and physiological insights. Furthermore, the clinical applications of such biomechanical knowledge on the mucosa are explored to address some critical concerns, including stimuli for tissue remodelling (interstitial hydrostatic pressure), pressure–pain thresholds, tissue displaceability and residual bone resorption. Through this review, the state of the art in mucosal biomechanics and their clinical implications are discussed for future research interests, including clinical applications, computational modelling, design optimization and prosthetic fabrication.

    This is a rare case report of a patient around 11 years with the complaint of extra mouth who reported to the hospital for removal of that extra mouth. On examination there was accessory oral cavity with small upper and lower lips, seven teeth and saliva was drooling out. Under general anesthesia crevicular incision from 32 to 43 was put and labial gingiva with alveolar mucosa was reflected completely and bone exposed to lower border of mandible. There were seven teeth resembling lower permanent anterior teeth in the accessory mouth, which was excised with the accessory lips. 41 extracted and osteotomy carried out extending the incision from the extracted site and osteotomy carried out. Dermoid cyst both below and above the mylohyoid muscle and rudimentary tongue found and excised and the specimen sent for histopathological examination. The wound was closed and uneventful healing noted to the satisfaction of the patient. This is a rare and interesting case which has been documented. PMID:23833508

  15. Novel oral anticoagulants.

    PubMed

    Reiffel, James A

    2014-04-01

    Warfarin has a proven record as an oral anticoagulant; almost every study, however, has found that it is not prescribed for 40-60% of patients who are eligible and should receive it, and of those who do receive it, serum warfarin levels only achieved a time in therapeutic range (TTR) equal to INR 2-3 about 55-60% of the time (online video available at: http://education.amjmed.com/video.php?event_id=445&stage_id=5&vcs=1). This means that only about 1 in 4 patients are adequately anticoagulated with warfarin, and thus there is a large unmet need for achieving better anticoagulation in these patients. Although physicians have sometimes tried to use antiplatelet therapy (aspirin, plus or minus clopidogrel) for anticoagulation, this may result in as much as a doubling of the risk of thromboembolic events. Recently 2 new classes of oral anticoagulant agents have appeared: direct thrombin inhibitors (DTIs) and factor Xa inhibitors. This review sequentially examines the recent clinical trial evidence for the 3 approved NOACs in the 2 classes, highlighting that all 3 share a class effect of being noninferior to warfarin for reducing risk of stroke and systemic embolization and reducing risk of bleeding, with a relative risk of mortality consistently reduced by 10% per year. In addition, all of the NOACs have a significantly lower risk of intracranial/intracerebral bleeding than warfarin, an important clinical consideration, since that is the most feared bleeding risk and may be sufficient reason to consider switching patients from warfarin to a NOAC, even if they seem to be doing well on warfarin. Finally in addition to reviewing the overall benefits of these NOACs over traditional therapy, the clinical application differences between the classes and between the agents are reviewed.

    2007-01-01

    Objectives In dentistry, the results of in vivo studies on drugs, dental fillings or prostheses are routinely evaluated based on selected oral cavity environment parameters at specific time points. Such evaluation may be confounded by ongoing changes in the oral cavity environment induced by diet, drug use, stress and other factors. The study aimed to confirm oral cavity environment changeability. Methods 24 healthy individuals aged 20–30 had their oral cavity environment prepared by having professional hygiene procedures performed and caries lesions filled. Baseline examination and the examination two years afterwards, evaluated clinical and laboratory parameters of oral cavity environment. Caries incidence was determined based on DMFT and DMFS values, oral cavity hygiene on Plaque Index (acc. Silness & Loe) and Hygiene Index (acc. O’Leary), and the gingival status on Gingival Index (acc. Loe & Silness) and Gingival Bleeding Index (acc. Ainamo & Bay). Saliva osmolarity, pH and concentrations of Ca2+, Pi, Na+, Cl−, total protein, albumins, F− and Sr2+ were determined. Results The results confirmed ongoing changeability of the oral cavity environment. After 2 years of the study reduction in oral cavity hygiene parameters PLI and HI (P<0.1), and gingival indices as well as lower saliva concentration of Ca2+ (P<.001), Pi (P<.06), K+ (P<.04), Sr2+ (P<.03), Na+ (P<.1), against the baseline values, were observed. Total protein and albumin saliva concentrations were also significantly lower. Conclusion Physiological oral cavity environment is subject to constant, individually different, changes which should be considered when analysing studies that employ oral cavity environment parameters.

  17. 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

    Background Peanut-allergic subjects have highly stable pathologic antibody repertoires to the immunodominant B cell epitopes of the major peanut allergens Ara h 1-3. Objective We used a peptide microarray technique to analyze the effect of treatment with peanut oral immunotherapy (OIT) on such repertoires. Methods Measurements of total peanut-specific IgE (psIgE) and psIgG4 were made with CAP-FEIA. We analyzed sera from 22 OIT subjects and 6 controls and measured serum specific IgE and IgG4 binding to epitopes of Ara h 1-3 using a high-throughput peptide microarray technique. Antibody affinity was measured using a competitive peptide microarray as previously described. Results At baseline, psIgE and psIgG4 diversity were similar between subjects and controls, and there was broad variation in epitope recognition. After a median 41 months of OIT, polyclonal psIgG4 increased from a median 0.3 mcg/mL (IQR 0.1-0.43) at baseline to 10.5 mcg/mL (3.95-45.48) (p<0.0001) and included de novo specificities. PsIgE was reduced from a median baseline of 85.45 kUA/L (23.05-101.0) to 7.75 kUA/L (2.58-30.55) (p<0.0001). Affinity was unaffected. Although the psIgE repertoire contracted in most OIT-treated subjects, several subjects generated new IgE specificities even as the total psIgE decreased. Global epitope-specific shifts from IgE to IgG4 binding occurred, including at an informative epitope of Ara h 2. Conclusion OIT differentially alters Ara h 1-3 binding patterns. These changes are variable between subjects, not observed in controls, and include a progressive polyclonal increase in IgG4, with concurrent reduction in IgE amount and diversity. PMID:23199605

    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

    The oral health is influenced by systemic health, and one of the most common chronic diseases encountered in dental practice is diabetes mellitus. Diabetes can worsen oral infections and vice versa. In the literature, periodontitis and diabetes in the young to middle-aged adults have been the most widely researched area. Understanding the patho-physiology, clinical manifestations and management of different types of orofacial diseases in diabetic patients are important to the diabetologist and the dentist for the optimal care of patients with these diseases.

    Smoking is estimated to cause 6.3 million deaths annually worldwide. The use of snuff, differing from smoking, has significantly increased especially among the adolescents. Snuff powder contains 20-fold more nicotine compared to cigarettes, leading to strong nicotine addiction. In addition to cancer development, both smoking and snuff use exert other risks for oral health. Compared with non-smokers, smokers are at a 10-fold risk for the development and progression of periodontal diseases. Snuff causes oral mucosal changes, gingival recessions and root surface caries. Smoking induces systemic low-grade inflammation, which weakens defensive immune responses in oral mucosa, gingiva, gingival crevicular fluid and saliva. PMID:26677547

Oral cysticercosis is a rare entity and represents difficulty in clinical diagnosis. This article reports two cases of oral cysticercosis involving buccal and labial mucosa. Both the cases presented with solitary, nodular swelling that had been clinically diagnosed as a mucocele. Histopathology of excisional biopsy revealed it to be cysticercosis. Single, cystic nodular swelling of oral cavity may be the only evidence of cysticercosis and may present first to dentist. These cases emphasise the role of dentist and thorough histopathological examination in the early diagnosis of disease that can prevent potential systemic complication. PMID:23580668

    Certain antithrombotic drugs exhibit high patient-to-patient variability that significantly impacts the safety and efficacy of therapy. Pharmacogenetics offers the possibility of tailoring drug treatment to patients based on individual genotypes, and this type of testing has been recommended for 2 oral antithrombotic agents, warfarin and clopidogrel, to influence use and guide dosing. Limited studies have identified polymorphisms that affect the metabolism and activity of newer oral antithrombotic drugs, without clear evidence of the clinical relevance of such polymorphisms. This article provides an overview of the current status of pharmacogenetics in oral antithrombotic therapy. PMID:27514462

    2013-02-01

    The prevalence of diabetes mellitus is increasing dramatically worldwide, resulting in more and more women of reproductive age being affected by either type 1 or type 2 diabetes. Management of contraception is a major issue due to the specific risks associated with pregnancy and those potentially induced by hormonal contraceptives in diabetic women. This review emphasizes the urgent need to improve the use of contraception in women with diabetes. There is no consistent evidence that combined oral contraceptives significantly influence the risk of developing diabetes, even in women with a history of gestational diabetes. Furthermore, although data from specific studies remain sparse, no worsening effect has been reported in diabetic women, either in glycemic control or on the course of microvascular complications. Thus, the use of estroprogestive pills is now recognized as a safe and effective option for preconception care of women with uncomplicated diabetes. According to recent guidelines, these contraceptives must be avoided in case of associated cardiovascular risk factors, cardiovascular disease or severe microvascular complications such as nephropathy with proteinuria or active proliferative retinopathy. Prescription of combined hormonal contraception in type 2 diabetic women must also be considered with caution due to a frequent association with obesity and vascular risk factors which increase both thromboembolic and arterial risks. Thanks to their metabolic and vascular safety profile, progestin-only contraceptives, as well as non-hormonal methods, represent alternatives according to patient wishes. PMID:23384747

    Tigemonam is an orally administered monobactam. At less than or equal to 1 microgram/ml it inhibited the majority of strains of Escherichia coli, Klebsiella spp., Enterobacter aerogenes, Citrobacter diversus, Proteus spp., Providencia spp., Aeromonas hydrophila, Salmonella spp., Shigella spp., Serratia marcescens, and Yersinia enterocolitica. At less than or equal to 0.25 microgram/ml it inhibited Haemophilus spp., Neisseria spp., and Branhamella catarrhalis. It did not inhibit Pseudomonas spp. or Acinetobacter spp. Tigemonam was more active than cephalexin and amoxicillin-clavulanate and inhibited many members of the family Enterobacteriaceae resistant to trimethoprim-sulfamethoxazole and gentamicin. Some Enterobacter cloacae and Citrobacter freundii strains resistant to aminothiazole iminomethoxy cephalosporins and aztreonam were resistant to tigemonam. The MIC for 90% of hemolytic streptococci of groups A, B, and C and for Streptococcus pneumoniae was 16 micrograms/ml, but the MIC for 90% of enterococci, Listeria spp., Bacteroides spp., and viridans group streptococci was greater than 64 micrograms/ml. Tigemonam was not hydrolyzed by the common plasmid beta-lactamases such as TEM-1 and SHV-1 or by the chromosomal beta-lactamases of Enterobacter, Morganella, Pseudomonas, and Bacteroides spp. Tigemonam inhibited beta-lactamases of E. cloacae and Pseudomonas aeruginosa but did not induce beta-lactamases. The growth medium had a minimal effect on the in vitro activity of tigemonam, and there was a close agreement between the MICs and MBCs. PMID:3279906

    A laboratory study was undertaken with volunteer females (aged 20-25) to determine the effect of OCs (oral contraceptives) on hematologic and metabolic variables during exercise. 5 of the women studied were naturally cycling and 7 were taking OCs. The women worked at 2 workloads on a bicycle ergometer at 50% and 90% of their maximal aerobic capacity during 3 different phases of their menstrual cycle. There was no better time of the month for doing the 50% or the 90% workload in either group. Heartrate for the OC group was significantly higher at the 50% maximal capacity. Results of the test indicate tha women on OCs have somewhat reduced cardiac efficiency and are ventilating more to carry out a given amount of work when compared to women who are naturally cycling. Possible explanations for the higher heart rate are put forward. The main limitation of the study is that the subject numbers involved are small and the number of cycles studied is also small.

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.

    Synopsis Demographic changes over the coming decades will heighten the challenges to the dental profession and to the nation. The expected growth in the numbers of racial and ethnic minorities, and the concomitant growth of immigrant populations are likely to lead to worsening of oral health disparities. Their consequences are becoming increasingly evident as the profession strives to improve the oral health of all Americans. The increasing diversity of the population, together with the importance of cultural beliefs and behaviors that affect health outcomes, will require ways to enhance provider-patient communications and oral health literacy. We discuss the nature and challenges presented by multicultural patient populations. One important means by which to promote oral health in diverse populations is to develop a dental workforce that is both culturally and linguistically competent, as well as one that is as culturally diverse as the American population.

    Multiple sclerosis (MS) is a complex autoimmune disease of the central nervous system. Disease-modifying drugs licensed for MS treatment have been developed to reduce relapse rates and halt disease progression. The majority of current MS drugs involve regular, parenteral administration, affecting long-term adherence and thus reducing treatment efficacy. Over the last two decades great progress has been made towards developing new MS therapies with different modes of action and biologic effects. In particular, oral drugs have generated much interest because of their convenience and positive impact on medication adherence. Fingolimod was the first launched oral treatment for relapsing-remitting MS; recently, Teriflunomide and Dimethyl fumarate have also been approved as oral disease-modifying agents. In this review, we summarize and discuss the history, pharmacodynamics, efficacy, and safety of oral agents that have been approved or are under development for the selective treatment of MS.

    Nine cases of oral extranodal lymphomas are described. Histologically, 6 cases were histiocytic, 2 lymphocytic and 1 Burkitt's lymphoma. According to the criteria of the Japanese Lymphoma Study Group, 8 cases seemingly belonged to the B-cell lymphoma classification, and one was unclassified. Geographical differences in the distribution of oral extranodal lymphomas between Japan and western countries were surveyed. A review of our cases and those in the literature revealed no significant difference in sex, age, frequency of B-cell lymphomas or site of predilection. In Japan, histiocytic lymphomas were the most common type of extranodal oral lymphomas. The most prevalent type of oral extranodal lymphomas in western countries could not be determined from the literature. PMID:6808100

    Precancerous lesions of oral mucosa, known as potentially malignant disorders in recent years, are consists of a group of diseases, which should be diagnosed in the early stage. Oral leukoplakia, oral submucous fibrosis, and oral erythroplakia are the most common oral mucosal diseases that have a very high malignant transformation rate. Oral lichen planus is one of the potentially malignant disorders that may be seen in six different subtypes including papular, reticular, plaque-like, atrophic, erosive, and bullous type, clinically. Atrophic and erosive subtypes have the greater increased malignant transformation risk compared to another subtypes. Although there are various etiological studies, the etiology of almost all these diseases is not fully understood. Geographically, etiologic factors may vary. The most frequently reported possible factors are tobacco use, alcohol drinking, chewing of betel quid containing areca nut, and solar rays. Early diagnosis is very important and can be lifesaving, because in late stages, they may be progressed to severe dysplasia and even carcinoma in situ and/or squamous cell carcinoma. For most diseases, treatment results are not satisfactory in spite of miscellaneous therapies. While at the forefront of surgical intervention, topical and systemic treatment alternatives such as corticosteroids, calcineurin inhibitors, and retinoids are widely used. PMID:25516862

  3. Oral rehydration therapy.

    Oral rehydration solution (ORS), the best treatment of dehydration due to acute diarrhea, is the most important medical advance of this century since it is key to reducing infant and child morbidity and mortality. Pathogens responsible for acute diarrhea include those which produce enterotoxin at the intestinal mucosal surface, inducing secretion but are not invasive (e.g., Vibrio cholerae); those which invade and disrupt the mucosal lining (e.g., shigella species); and rotavirus. The World Health Organization (WHO)/UNICEF ORS is considered a universal ORS. Much research has been done on the ideal composition of an ORS. An ORS must have sufficient sodium to replace losses on a volume to volume basis, a glucose concentration that matches that of sodium to ensure its delivery to the ileum, sufficient amounts of potassium and base (e.g., sodium bicarbonate or trisodium citrate dihydrate) to correct acidosis and to enhance sodium absorption, and sufficient amounts of liquid. The risk of hypernatremia with use of the WHO/UNICEF ORS is a concern since infants and young children have an immature renal concentrating capacity, increased insensible water losses, and an impaired natriuretic response. Neonates and young infants may be prone to relatively slow correction of acidosis. It appears that the potassium content (20 mmol/l) of WHO-ORS should be higher to promote a net positive potassium retention. Too much glucose in the ORS will induce reverse osmosis of water into the gut, effectively making the ORS a dehydrating solution rather than a hydrating solution. Some carbohydrates other than glucose have proven effective glucose substitutes (e.g., sucrose, rice starch and powder, other cereals). Cereals have higher acceptability levels in developing countries. Research is investigating the nutritional benefits of supplementing ORS with micronutrients (e.g., vitamin A, folic acid, and zinc). ORS use with early refeeding has a beneficial effect on nutritional status after an

    Background and aims. Many oral squamous cell carcinomas develop from potentially malignant disorders (PMDs)which include a variety of lesions and conditions characterized by an increased risk for malignant transformation. Thisstudy evaluated the quantitative expression of EGFR in normal oral mucosa, oral leukoplakia and oral submucous fibrosis to predict the malignant risk in compliance with the intensity of staining with EGFR. Materials and methods. Thirty subjects were included in the study, consisting of 10 oral leukoplakia (OL), 10 oral submucous fibrosis (OSMF) and 10 normal oral mucosa (NOM) as the control group. Owing to the histopathological confirmation of precancerous state of tissue, 4-μm-thick sections of tissue were taken from paraffin-embedded wax blocks for immunohistochemical staining for EGFR. Results. All the control cases showed positive expression for EGFR, while 20% of oral leukoplakia and 40% of OSMF cases showed strong expression (3+), 40% of OL and 30% of OSMF cases showed weak expression (2+), and 40% of OLand 30% of OSMF cases showed poor expression (1+) compared to controls (P=0.012). Conclusion. EGFR expression levels in the premalignant lesion appear to be a sensitive factor in predicting the neoplastic potential. This suggests that EGFR may serve as a biological marker to identify high-risk subgroups and guide prophylactic therapy with chemopreventive drugs or surgical intervention to prevent progression to carcinoma. Hence, further investigations in the direction of chemopreventive trials with a larger sample size are suggested to determine its role in the head and neck tumorigenesis. PMID:26697149

    Purpose The primary objective of this study was to determine the maximum tolerated dose (MTD) of intravenously (i.v.) calcitriol administered in combination with a fixed oral dose of dexamethasone and gefitinib in patients with refractory solid tumors. Methods A fixed oral dose of dexamethasone of 4 mg/day was given every 12 h × 3 doses starting 12 h prior to i.v. calcitriol administration. Calcitriol was administered i.v. over 1 h on weeks 1, 3, and weekly thereafter. The starting calcitriol dose level was 57 μg and escalation occurred in cohorts of three patients until the MTD was defined. Gefitinib was given at a fixed oral daily dose of 250 mg starting at week 2 (day 8). Serum calcitriol PK studies were performed on day 1 (calcitriol + dexamethasone) and on day 15 (calcitriol + dexamethasone + gefitinib). Results A total of 20 patients were treated. Dose-limiting hypercalcemia was observed in two out of the four patients receiving 163 mcg/week of calcitriol. Mean (±SE) peak serum calcitriol concentration (Cmax) at the MTD (125 μg/week calcitriol) was 11.17 ± 2.62 ng/ml and the systemic exposure (AUC0–72 h) of 53.30 ± 10.49 ng h/ml. The relationship between calcitriol dose and either Cmax or AUC was linear over the 57–163 μg dose range. Conclusions The addition of a low dose of dexamethasone allowed the safe escalation of calcitriol to the MTD of 125 μg/week. This dose level resulted in serum calcitriol concentrations that are associated with pre-clinical antitumor activity. However, no antitumor activity was noted clinically in patients with solid tumors. PMID:19396601

    Aphthous ulcers are painful ulcerations located on the mucous membrane, generally in the mouth, less often in the genital area. Three clinical forms of aphthous ulcers have been described: minor aphthous ulcers, herpetiform aphthous ulcers and major aphthous ulcers. Many other conditions presenting with oral bullous or vesiculous lesions orulcerations and erosions can be mistaken for aphthous ulcers. Currently, treatment of aphthous ulcers is palliative and symptomatic. Topical treatments (topical anesthetics, topical steroids and sucralfate) are the first line therapy. Recurrent aphthous stomatitis (RAS) is defined by the recurrence of oral aphthous ulcers at least 4 times per year. RAS is often idiopathic but can be associated with gastro-intestinal diseases (i.e. celiac disease, inflammatory bowel diseases), nutritional deficiencies (iron, folates...), immune disorders (HIV infection, neutropenia) and rare syndromes. Behçet's disease is a chronic, inflammatory, disease whose main clinical feature is recurrent bipolar aphthosis. Colchicine associated with topical treatments constitutes a suitable treatment of most RAS. Thalidomide is the most effective treatment of RAS but its use is limited by frequent adverse effects. Oral ulcers can be related to a wide range of conditions that constitute the differential diagnoses of aphthous ulcers. Oral ulcers are classified into three main groups: acute ulcers with abrupt onset and short duration, recurrent ulcers (mainly due to postherpetic erythema multiforme) and chronic ulcers (with slow onset and insidious progression). Acute oral ulcers are due to trauma, bacterial infections (including acute necrotizing ulcerative gingivitis), deep fungal infection, gastro-intestinal (namely inflammatory bowel disease) or systemic diseases. Chronic oral ulcers may be drug-induced, or due to benign or malignant tumors. Every oral solitary chronic ulcer should be biopsied to rule out squamous cell carcinoma. A solitary palatal ulcer

    Oral contraceptive (OC) options for adolescents are provides. Clarification for those desiring a birth control method is necessary and the benefits of decreased acne and dysmenorrhea with low dose OCs should be stressed along with the importance of compliance. A community effort is suggested to communicate the sexual and contraceptive alternatives, including abstinence and outercourse (sexual stimulation to orgasm without intercourse). Attention is given to concerns associated with teenage sexual activity, prevention of adolescent pregnancy, contraceptive options for the adolescent patient, adolescent attitudes toward birth control OCs, management of the adolescent OC user, manipulation of steroid components of OCs to respond to adolescent concerns, and other hormonal contraceptive options such as minipills or abstinence. The text is supplemented with tables: the % of US women by single years of age for 1971, 1976, 1979, and 1982; comparative pregnancy and abortion rates for the US and 5 other countries; federal cost for teen childbearing; adolescent nonhormonal contraceptive methods (advantages, disadvantages, and retail cost); checklist to identify those at risk for noncompliance with OCs; hormonal side effects of OCs; risks from OCs to adolescents; and benefits of OCs. Concern about adolescent pregnancy dates back to Aristotle. A modern profile shows girls form single-parent families are sexually active at an earlier age, adolescent mothers produce offspring who repeat the cycle, victims of sexual abuse are more likely to be sexually active, and teenagers in foster care are 4 times more likely to be sexually active and 8 times more likely to become pregnant. Prevention involves a multifaceted approach. OCs are the most appropriate contraceptive choice for adolescents. Frequency of intercourse is closely associated with OC use after approximately 15 months of unprotected sexual activity. At risk for noncompliance variables are scales of personality development

    Individual bacteria and shifts in the composition of the microbiome have been associated with human diseases including cancer. To investigate changes in the microbiome associated with oral cancers, we profiled cancers and anatomically matched contralateral normal tissue from the same patient by sequencing 16S rDNA hypervariable region amplicons. In cancer samples from both a discovery and a subsequent confirmation cohort, abundance of Firmicutes (especially Streptococcus) and Actinobacteria (especially Rothia) was significantly decreased relative to contralateral normal samples from the same patient. Significant decreases in abundance of these phyla were observed for pre-cancers, but not when comparing samples from contralateral sites (tongue and floor of mouth) from healthy individuals. Weighted UniFrac principal coordinates analysis based on 12 taxa separated most cancers from other samples with greatest separation of node positive cases. These studies begin to develop a framework for exploiting the oral microbiome for monitoring oral cancer development, progression and recurrence. PMID:24887397

    2006-08-01

    Over the last decade there have been considerable developments in the use of oral fluid (saliva) for drug testing. Oral fluid can provide a quick and non-invasive specimen for drug testing. However, its collection may be thwarted by lack of available fluid due to a range of physiological factors, including drug use itself. Food and techniques designed to stimulate production of oral fluid can also affect the concentration of drugs. Current applications are mainly focused on drugs of abuse testing in employees at workplaces where drug use has safety implications, in drivers of vehicles at the roadside and in other situations where drug impairment is suspected. Testing has included alcohol (ethanol) and a range of clinical tests eg antibodies to HIV, therapeutic drugs and steroids. Its main application has been for testing for drugs of abuse such as the amphetamines, cocaine and metabolites, opioids such as morphine, methadone and heroin, and for cannabis. Oral fluid concentrations of basic drugs such as the amphetamines, cocaine and some opioids are similar or higher than those in plasma. Tetrahydrocannabinol (THC), the major species present from cannabis use, displays similar concentrations in oral fluid compared to blood in the elimination phase. However, there is significant local absorption of the drug in the oral cavity which increases the concentrations for a period after use of drug. Depot effects occur for other drugs introduced into the body that allow local absorption, such as smoking of tobacco (nicotine), cocaine, amphetamines, or use of sub-lingual buprenorphine. Screening techniques are usually an adaptation of those used in other specimens, with an emphasis on the parent drug since this is usually the dominant species present in oral fluid. Confirmatory techniques are largely based on mass spectrometry (MS) with an emphasis on Liquid Chromatography-Mass Spectrometry (LC-MS), due to low sample volumes and the low detection limits required.

    The population of individuals aged 65 and older is growing dramatically and is expected to increase 126% by 2011, compared to only a 42% rise in the population of the United States as a whole. The fastest growing segment of the older adult population is persons aged 85 and older (Figure 1). Although many members of this generation lead healthy independent lives, the challenge faced by oral health care professionals is providing care to the chronically ill and/or homebound or institutionalized older adult, particularly the oldest old and those with limited finances. Effective communication skills are essential when dealing with older adults and their families. Collaboration between medical/allied health professionals and oral health care professionals is also critical in order to accurately assess and manage the oral health needs of the aging patient. A preventive approach to oral health with sensitivity to the physical, mental, and social status of the patient is the focus of this course. Marketing strategies to alleviate common barriers to seeking oral health care among this age group are provided. PMID:12861793

    Purpose A Head Start program located in Paterson, New Jersey considered establishing a school-based dental clinic to address unmet oral health needs such as access to care and the need for restorative treatment. The purpose of this study was to establish the oral health status of Head Start children, their treatment needs, and parents' interest and willingness to utilize a school-based dental clinic. Description School-based dental care has been used to address access to care issues, particularly among children who live in underserved areas. A 21 item survey was used to correlate the results of an oral exam performed on the Head Start children and the parents' preferences, beliefs and access patterns. Fisher's exact test and Chi squared test were used to study the association among variable with significance levels set at 0.05. Assessment The oral exam revealed a high caries rate amongst all of the children. Parental responses indicated strong support for the establishment of a school-based clinic and identified the need for further parental education. Having a regular source of care was found to be unrelated to treatment needs. Conclusion Further education of the parents regarding the child's oral health is critical to the success and viability of this school-based clinic. PMID:27017227

    Helicobacter pylori is an important pathogen involved in the development of gastrointestinal ulcers, but its involvement in oral ulcerous lesions is unclear. As culture is generally recognized as the gold standard for diagnosis of H. pylori infection, we employed this approach to assess the association of H. pylori with oral mucosal ulcerations. Samples were collected from patients with oral mucosal ulcerative disorders: 12 cases of recurrent aphthous stomatitis (RAS), 7 cases of herpes simplex virus (HSV) stomatitis, and 3 cases of erosive lichen planus (LP). Serum IgG antibodies against H. pylori were examined in all cases. All of the RAS and erosive LP cases were culture-negative for H. pylori, while two cases of HSV stomatitis were positive. The two culture-positive cases were also seropositve for the H. pylori antigen. It is suggested that H. pylori might not have a direct association with oral ulcerations. However, H. pylori in the oral cavity might exist in a non-culturable coccoid state without productive infection, and might form colonies only under special conditions such as HSV infection.

    The predominant diet fed to captive carnivores in North America consists of ground meat formulated to provide full nutritional requirements. However, this ground meat diet completely lacks the mechanical properties (i.e., toughness and hardness) of the foods these animals would consume in the wild. The goal of this study is to evaluate the effect of captivity on oral health by comparing the prevalence of periodontal disease and dental calculus accumulation in wild and captive lions and tigers (Panthera leo and Panthera tigris), and to also correlate oral health with cranial morphology in these specimens. To achieve this, 34 adult lion and 29 adult tiger skulls were scored for the presence and extent of dental calculus and periodontal disease. These oral health scores were also compared to cranial deformations examined in a previous study. We found that the occurrence and severity of calculus buildup and periodontal disease was significantly higher in captive felids compared to their wild counterparts. Further, higher calculus accumulation occurred on the posterior teeth when compared to the anterior teeth, while an opposite trend for periodontal disease was observed. We also found a significant correlation between oral health and cranial morphology of lions and tigers. The results suggest that food mechanical properties are significant factors contributing to oral health in felids. PMID:27473998

    Pigmented oral lesions compose a large number of pathological entities, including exogenous pigmentat oral tattoos, such as amalgam and graphite tattoos. We report a rare case of a graphite tattoo on the palate of a 62-year-old patient with a history of pencil injury, compare it with amalgam tattoos, and determine the prevalence of oral tattoos in our Oral Pathology Service. We also compare the clinical and histological findings of grafite and amalgam tattoos. Oral tattoos affect women more frequently in the region of the alveolar ridge. Graphite tattoos occur in younger patients when compared with the amalgam type. Histologically, amalgam lesions represent impregnation of the reticular fibers of vessels and nerves with silver, whereas in cases of graphite tattoos, this impregnation is not observed, but it is common to observe a granulomatous inflammatory response, less evident in cases of amalgam tattoos. Both types of lesions require no treatment, but in some cases a biopsy may be done to rule out melanocytic lesions. PMID:26632800

    Oral vaccination is the most challenging vaccination method due to the administration route. However, oral vaccination has socio-economic benefits and provides the possibility of stimulating both humoral and cellular immune responses at systemic and mucosal sites. Despite the advantages of oral vaccination, only a limited number of oral vaccines are currently approved for human use. During the last decade, extensive research regarding antigen-based oral vaccination methods have improved immunogenicity and induced desired immunological outcomes. Nevertheless, several factors such as the harsh gastro-intestinal environment and oral tolerance impede the clinical application of oral delivery systems. To date, human clinical trials investigating the efficacy of these systems are still lacking. This review addresses the rationale and key biological and physicochemical aspects of oral vaccine design and highlights the use of yeast-derived β-glucan microparticles as an oral vaccine delivery platform.

    We assessed the utility of expert oral examination as a part of the diagnostic evaluation of patients with suspected Crohn's disease. Of 45 patients with newly diagnosed CD, 25 had been examined by a dentist. Twelve (48%) of these had oral CD lesions. Mucosal tags constituted the most frequent form of oral lesion (8/12). Of 8 oral biopsy specimens, 6 (75%) contained non-caseating granulomas. Patients with oral CD had more oral symptoms, presented for diagnosis sooner, and were more likely to have other upper gastrointestinal inflammation than those without oral lesions. Oral manifestations of CD are common in children; therefore, expert oral examination may be useful during diagnostic evaluation of children with suspected inflammatory bowel disease. PMID:11343060

    The main purpose of this paper was to assess the current state of science on oral leukoplakia. Although it is considered a potentially malignant disorder the overall malignant progression of oral leukoplakia is of the order of 5% and even more. Nowadays there are no currently accepted markers to distinguish those that may progress to cancer from those that may not. The current golden standard is considered the presence of epithelial dysplasia on the tissue biopsy of the lesion. Proliferative verrucous leukoplakia is a rare form of OL which has multiple recurrences, is refractory to treatment and has malignant transformation in a short period. It is considered a true premalignant lesion. The management of oral leukoplakia varies from a "wait and see" attitude and topical chemopreventive agents to complete surgical removal. PMID:25553134

    Background Despite advancements in oral health policies, dental caries still a problem. The lack of parents/caregiver’s care regarding child’s oral health, which characterizes neglect, may lead to a high prevalence of caries. Therefore, the objective of this study was to analyze the relation between dental caries and neglect in five year-old children. Methods Quantitative study performed in two different moments. First, the children underwent oral examinations and physical inspection. Then, a semi-structured interview was performed with parents of children with high and low caries rate. Results In all, 149 physical inspections and oral exams were performed. The number of decayed, missing and filled teeth – dmf-t was 2.75 (SD 2.83); 16 children had extremely high values (dmf-t ≥7), 85 intermediate values (1 ≤ dmf-t ≥ 6) and 48 extremely low (dmf-t = 0). Nearly all caregivers were female (96.7%; n = 29), mostly mothers (93.3%; n = 28). Associations were found between caries experience and reason of the last consultation (p = 0.011), decayed teeth and child’s oral health perception (p = 0.001). There was a trend towards a significant association between general health and decayed teeth (p = 0.079), general hygiene and caries experience (p = 0.083), and caries experience and number of times the child brushes the teeth (p = 0.086). Conclusion There’s a relation between caries experience and children’s oral health perception by caregivers, as well as between caries experience and children’s access to dental care. There is a trend towards association between caries experience and risk factors suggestive of neglect. PMID:24238222

    This article reviewed smoking related systemic diseases and oral diseases. Smoking is related to lung cancer, cardiovascular diseases and many other systemic diseases. Cigarette smoke affects the oral cavity first, so it is evident that smoking has many negative influences on oral cavity, for example, staining of teeth and dental restorations, wound healing, reduction of the ability to smell and taste, and development of oral diseases such as oral cancer, periodontitis, smoker's palate, smoker's melanosis, hairy tongue, leukoplakia, oral candidiasis and implant survival rate. The article also discusses the relationship between smoking and dental caries in detail. PMID:18254267

    3,4-methylenedioxymethamphetamine (MDMA), more commonly known as 'ecstasy' or XTC, is frequently used by young adults in the major cities. Therefore, it is likely that dentists might be confronted with individuals who use ecstasy. This review describes systemic and oral effects of ecstasy. Life-threatening complications include hyperthermia, hyponatraemia and liver failure. In addition, psychotic episodes, depression, panic disorders and impulsive behaviour have been reported. Oral effects include xerostomia, bruxism, and an increased risk of developing dental erosion. Mucosal changes have also been reported. Recent use of ecstasy may interfere with dental treatment. Finally, the potential use of saliva for non-invasive detection of ecstasy is discussed. PMID:18268544

    Oral lesions are among the early signs of HIV infection and can predict its progression to acquired immunodeficiency syndrome (AIDS). A better understanding of the oral manifestations of AIDS in both adults and children has implications for all health care professionals. The knowledge of such alterations would allow for early recognition of HIV-infected patients. The present paper reviews epidemiology, relevant aspects of HIV infection related to the mouth in both adults and children, as well as current trends in antiretroviral therapy and its connection with orofacial manifestations related to AIDS.

    Cysticercosis, a helminthic disease commonly seen in India, Latin America, Eastern Europe and Southern Africa, results from extraintestinal encystation of the larval form of Taenia solium. It is a condition in which man acts as intermediate host instead of definitive host. The most frequent sites of cysticercosis are subcutaneous layers, brain, muscles, heart, liver, lungs, and peritoneum. Oral cysticercosis is considered rare and cause cystic swellings or nodules in the mouth and a precise clinical diagnosis is not usually established. Here, we report a case of oral cysticercosis in a 32-year-old female occurring in the mentalis muscle presenting as asymptomatic nodule. PMID:26266222

    Abstract Oral feeding for preterm infants has been a thorny problem worldwide. To improve the efficacy of oral feeding in preterm infants, oral motor intervention (OMI), which consists of nonnutritive sucking, oral stimulation, and oral support, was developed. Published studies demonstrated that OMI may be as an alternative treatment to solve this problem; however, these results remain controversial. We conducted a meta-analysis with trial sequential analysis (TSA) to objectively evaluate the potential of OMI for improving the current status of oral feeding in preterm infants. A search of PubMed, EMBASE, Web of Science, the Cochrane Library, and China National Knowledge Infrastructure was performed to capture relevant citations until at the end of October, 2014. Lists of references of eligible studies and reviews were also hand-checked to include any latent studies. Two independent investigators screened literature, extracted data, and assessed the methodology, and then a meta-analysis and TSA was performed by using Reviewer Manager (RevMan) 5.3 and TSA 0.9 beta, respectively. A total of 11 randomized controlled trials (RCTs), which included 855 participants, were incorporated into our meta-analysis. The meta-analyses suggested that OMI is associated with the reduced transition time (ie, the time needed from tube feeding to totally oral feeding) (mean difference [MD], −4.03; 95% confidence interval [CI], −5.22 to −2.84), shorten hospital stays (MD, −3.64; 95% CI, −5.57 to −1.71), increased feeding efficiency (MD, 0.08; 95% CI, 0.36–1.27), and intake of milk (MD, 0.14; 95% CI, 0.06–0.21) rather than weight gain. Results of TSA for each outcomes of interest confirmed these pooled results. With present evidences, OMI can be as an alternative to improve the condition of transition time, length of hospital stays, feeding efficiency, and intake of milk in preterm infants. However, the pooled results may be impaired due to low quality included, and thus

    Objectives. Even though objective data indicating the absence of oral malodor are presented to patients, they may be skeptical about the results, possibly due to the presence of some discomfort in the oral cavity. The objective of this study was to investigate whether there is an association among self-perceptions of oral malodor, oral complaints, and the actual oral malodor test result. Materials and Methods. Questions concerning self-perceptions of oral malodor and subjective intraoral symptoms were extracted from a questionnaire on oral malodor completed by 363 subjects who visited the clinic for oral malodor of Tokyo Dental College Chiba Hospital and gave consent to this study. In addition, the association of self-perception of oral malodor with values obtained after organoleptic and OralChroma measurement was analyzed. Results. No correlation between 195 subjects (54%) who were judged “with oral malodor” (organoleptic score of ≥1) and 294 subjects (81.6%) who had a self-perceptions of oral malodor was observed. Self-perception of oral malodor was significantly correlated with tongue coating (p = 0.002) and a strange intraoral taste (p = 0.016). Conclusions. Subjects with a self-perception of oral malodor were not necessarily consistent with those actually having an oral malodor. In addition, it was suggested that patients became aware of oral malodor when they felt oral complaints. PMID:26273303

    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.

    Polymorphisms in CYP2C9, a critical cytochrome P-450 enzyme in the metabolism of warfarin, alters its clearance and affects dosing. CYP*1 has higher activity than either the *2 or *3 variants, and patients with the *2 or *3 variants require a lower dose. VKORC1 is the enzyme inhibited by warfarin, and its levels are affected by several polymorphisms that can be divided into high or low level haplotypes, and patients with high level haplotypes require higher warfarin doses. The use of algorithms for dosing that incorporate pharmacogenomic information perform better than those using clinical data alone. Considerable effort is ongoing to develop new oral anticoagulants as alternatives to warfarin, and three agents are in advanced development. Dabigatran is an oral direct thrombin inhibitor that has been compared with enoxaparin for prevention of VTE following hip or knee replacement. Based on non-inferiority results in European trials, it has now been approved for marketing in Europe. Phase III trials with a new oral Xa inhibitor, rivaroxaban, have been completed in hip or knee replacement, and rivaroxaban was superior to enoxaparin in prevention of VTE with no increase in bleeding complications. Phase III studies with apixaban, another oral Xa inhibitor, are in progress. These agents are also being evaluated in large studies for prevention of stroke in atrial fibrillation and for VTE treatment. PMID:19074093

    Oral vaccination can offer a painless and convenient method of vaccination. Furthermore, in addition to systemic immunity it has potential to stimulate mucosal immunity through antigen-processing by the gut-associated lymphoid tissues. In this study we propose the concept that pollen grains can be engineered for use as a simple modular system for oral vaccination. We demonstrate feasibility of this concept by using spores of Lycopodium clavatum (clubmoss) (LSs). We show that LSs can be chemically cleaned to remove native proteins to create intact clean hollow LS shells. Empty pollen shells were successfully filled with molecules of different sizes demonstrating their potential to be broadly applicable as a vaccination system. Using ovalbumin (OVA) as a model antigen, LSs formulated with OVA were orally fed to mice. LSs stimulated significantly higher anti-OVA serum IgG and fecal IgA antibodies compared to those induced by use of cholera toxin as a positive-control adjuvant. The antibody response was not affected by pre-neutralization of the stomach acid, and persisted for up to seven months. Confocal microscopy revealed that LSs can translocate in to mouse intestinal wall. Overall, this study lays the foundation of using LSs as a novel approach for oral vaccination. PMID:25151980

    Last May, the New York State Dental Association and the New York State Dental Foundation convened the first "Oral Health Stakeholders' Summit on the Future of Special Needs Dentistry, Hospital Dentistry and Dental Education." The summit was chaired by David J. Miller, then NYSDA President Elect, and Carl H. Tegtmeier, then chair of the NYSDA Council on Dental Health Planning and Hospital Dentistry. It brought together experts, called to frame the issues and provide information necessary for a reasoned response. And it sought input from attendees to develop recommendations to ensure that patients with intellectual and developmental disabilities, as well as an aging population with Alzheimer's disease and dementia, have access to appropriate oral health care in the years ahead. Over 100 participants, representing dentistry, hospital training programs, third-party payers, state government offices and related patient support associations, attended the two-day event in Albany. They focused on the impact of reductions in funding, the transition of Medicaid services into a managed care model, a loss of service providers and the need for expanded training programs. They heard from speakers epresenting a broad spectrum of those involved in he oral health care of patients with intellectual and evelopmental disabilities, the Alzheimer's Association, dental educators and researchers, hospital dentistry and the benefits industry, whose presentations focused on a looming oral health crisis threatening access to dental care for patients with disabilities.

    1986-09-01

    We evaluated the absolute bioavailability of ciprofloxacin, a new quinoline carboxylic acid, in 12 healthy male volunteers. Doses of 200 mg were given to each of the volunteers in a randomized, crossover manner 1 week apart orally and as a 10-min intravenous infusion. Half-lives (mean +/- standard deviation) for the intravenous and oral administration arms were 4.2 +/- 0.77 and 4.11 +/- 0.74 h, respectively. The serum clearance rate averaged 28.5 +/- 4.7 liters/h per 1.73 m2 for the intravenous administration arm. The renal clearance rate accounted for approximately 60% of the corresponding serum clearance rate and was 16.9 +/- 3.0 liters/h per 1.73 m2 for the intravenous arm and 17.0 +/- 2.86 liters/h per 1.73 m2 for the oral administration arm. Absorption was rapid, with peak concentrations in serum occurring at 0.71 +/- 0.15 h. Bioavailability, defined as the ratio of the area under the curve from 0 h to infinity for the oral to the intravenous dose, was 69 +/- 7%. We conclude that ciprofloxacin is rapidly absorbed and reliably bioavailable in these healthy volunteers. Further studies with ciprofloxacin should be undertaken in target patient populations under actual clinical circumstances. PMID:3777908

    Standard methods to facilitate the collection of data on a global basis have been developed by WHO. Data collection in accordance with criteria proposed by WHO began in 1969 from existing sources and was subsequently supplemented by new data collected using the standard methods. Associated with these methods developments, a WHO Global Oral Epidemiology program was begun with the objective of facilitating comparison of data and their use in planning, replanning, and evaluating oral health services according to needs and economic possibilities. That program provides an orderly storage and retrieval system and a visual representation of contrasts in prevalence of those oral diseases which are among the most common known to man. In selecting data for inclusion in the WHO oral epidemiology data bank, a liberal policy has been pursued to make maximum use of available material. The system of classification allows for data retrieval at various levels and for specific ages. Data on caries are available for 95 countries and on periodontal diseases for 50 countries.

    Oral diseases, including dental caries, periodontal disease, and tooth loss, affect the majority of the population and can affect a person's overall health. Raisins contain polyphenols, flavonoids, and high levels of iron that may benefit human health. However, their oral health benefits are less well understood. We hypothesized that raisins contain antimicrobial phytochemicals capable of suppressing oral pathogens associated with caries or periodontal diseases and thus benefit oral health. Through antimicrobial assay-guided fractionation and purification, compounds identified with growth inhibition against oral pathogens were oleanolic acid, oleanolic aldehyde, linoleic acid, linolenic acid, betulin, betulinic acid, 5-(hydroxymethyl)-2-furfural, rutin, beta-sitosterol, and beta-sitosterol glucoside. Oleanolic acid suppressed in vitro adherence of cariogenic Streptococcus mutans biofilm. When the effect of raisins and raisin-containing bran cereal on in vivo plaque acidogenicity was examined in 7- to 11-y-old children, it was found that raisins did not reduce the plaque pH decline below pH 6 over the 30-min test period. Compared with commercial bran flakes or raisin bran cereal, a lower plaque pH drop was noted in children who consumed a raisin and bran flake mixture when no sugar was added (P < 0.05). Grape seed extract, high in proanthocyanidins, positively affected the in vitro demineralization and/or remineralization processes of artificial root caries lesions, suggesting its potential as a promising natural agent for noninvasive root caries therapy. Raisins represent a healthy alternative to the commonly consumed sugary snack foods. PMID:19640974

    Primary mucosal leishmaniasis is a rare infectious disease, particularly in immunocompetent patients. We present a 50-year-old patient with a 6-week history of a painful lesion of the left buccal mucosa that mimicked cancer. The exophytic lesion looked invasive, and we took an incisional biopsy specimen to exclude cancer. The diagnosis of leishmaniasis was unexpected, and the patient was successfully treated with amphotericin B for five weeks. After five months the patient had a visceral recurrence. Chronic exophytic and ulcerated mucosal lesions that do not heal within 3-4 weeks should be regarded as the first signs of oral cancer, but primary oral leishmaniasis can easily mimic it.

    Background. Oral squamous cell carcinoma is the sixth most frequent malignant tumor worldwide and the third most common cancers in developing countries. Oral leukoplakia is the best-known precursor lesion of oral squamous cell carcinoma. The aim of the present study was to compare immunohistochemical expression of antiapoptotic protein survivin in normal oral mucosa, oral leukoplakia, and oral squamous cell carcinoma. Method. Total 45 specimens of formalin fixed paraffin embedded tissue blocks, 15 in each of the following: normal oral mucosa, leukoplakia, and oral squamous cell carcinoma were used for the study. Immunohistochemical reaction for survivin protein was performed for the 4 µm thick histological sections taken on positively charged slides. Results. 20% normal mucosa cases, 53.33% cases of leukoplakia, and 80% of oral squamous cell carcinoma were found out to be survivin positive. One way ANOVA test indicated statistically significant difference of survivin expression between the three different groups (p < 0.001). Conclusion. A high incidence of survivin protein expression in oral epithelial dysplasia and squamous cell carcinoma samples indicate that survivin protein expression may be an early event in initiation and progression of oral squamous cell carcinoma.

    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. PMID:10518916

    The presence of a neurovascular hamartoma within the oral cavity is truly a rare entity. Scarcely reported in the literature, these hamartomas are smooth, pinkish masses and are painless, and therefore difficult to diagnose. They are benign in nature and apply pressure to their surroundings. The histological diagnosis remains the gold standard as it comprises of neural tissue and vascular components. Treatment is surgical excision with adequate margins. Recurrence is reported in cases of incomplete resection. PMID:24969068

    Pregnancy is a unique time in a woman's life and is characterized by complex physiological changes. These changes can adversely affect oral health. Pregnancy is also an opportune time to educate women about preventing dental caries in young children, a common childhood problem. Although multiple studies have shown an association between periodontal infection and adverse pregnancy outcomes, such as premature delivery and low birth weight, recent randomized clinical trials conducted in the United States failed to show that treatment of periodontal disease during pregnancy improved birth outcomes. However, the studies confirmed the safety and effectiveness of providing oral health care during pregnancy. Pregnancy by itself is not a reason to defer routine dental care and necessary treatment for oral health problems. Diagnosis and treatment, including needed dental X-rays, can be undertaken safely during the first trimester of pregnancy. Needed treatment can be provided throughout the remainder of the pregnancy; however, the time period between the 14th and 20th week is considered ideal. PMID:20069785

    Despite the common prevalence of cutaneous psoriasis, the existence of manifestations in the oral cavity is subject to controversy. In this article, dermatologic psoriasis is reviewed, and a patient with generalized, symptomatic oral mucosal erythema resembling atrophic candidiasis synchronous with flare of chronic skin psoriasis is described. Diagnostic work up and therapeutic response supported that these mucosal findings were the oral counterpart of cutaneous disease. Dental providers should be familiar with the signs and symptoms of oral psoriasis, institute appropriate preventive measures, and provide palliation directed at symptomatic oral changes of psoriasis.

    2005-06-10

    The potential to use oral fluid as a drug-testing specimen has been the subject of considerable scientific interest. The ease with which specimens can be collected and the potential for oral fluid (OF) drug concentrations to reflect blood-drug concentrations make it a potentially valuable specimen in clinical as well as forensic settings. However, the possible effects of the OF collection process on drug detection and quantification has often been over looked. Several studies have documented that drug-contamination of the oral cavity may skew oral fluid/blood drug ratios and confound interpretation when drugs are smoked, insufflated or ingested orally. OF pH is predicted to have an effect on the concentration of drugs in OF. However, in a controlled clinical study, the effect of pH was less than that of collection technique. Mean codeine OF concentrations in specimens collected a non-stimulating control method were 3.6 times higher than those in OF collected after acidic stimulation. Mean codeine concentrations were 50% lower than control using mechanical stimulation and 77% of control using commercial collection devices. Several factors should be considered if a commercial OF collection device is used. In vitro collection experiments demonstrated that the mean collection volume varied between devices from 0.82 to 1.86 mL. The percentage of the collected volume that could be recovered from the device varied from 18% to 83%. In vitro experiments demonstrated considerable variation in the recovery of amphetamines (16-59%), opiates (33-50%), cocaine and benzoylecgonine (61-97%), carboxy-THC (0-53%) and PCP (9-56%). Less variation in collection volume, volume recovered and drug recovery was observed intra-device. The THC stability was evaluated in a common commercial collection protocol. Samples in the collection buffer were relatively stable for 6 weeks when stored frozen. However, stability was marginal under refrigerated conditions and poor at room temperature. Very

    Oral cancers often occurs out of long standing potentially malignant lesions and conditions so called premalignant lesions and conditions. Oral precancer is a intermediate state with increased cancer rate which can be recognized and treated obviously with much better prognosis than a full blown malignancy. Oral cancer risk can be lowered or even prevented by simply understanding basic oral hygiene, different bacteria found in the mouth, and how diet influences oral cancers. Currently, research is being done on the relationship between diet and oral cancer. Oral cancer is a very serious disease that can be prevented. Practicing good oral hygiene is key to help keep the oral cavity clean. Limiting the use of tobacco and alcohol products is also important because these are the causes of most oral cancers. Lastly, eating a well balanced diet that has protective affects can reduce the risk of oral cancer. This includes a diet high in fruits, vegetables, and fish and low in high fat and cholesterol meats, rice, and refined grains. PMID:25625069

    It is well known that bacteria are the primary cause of infectious diseases, however, evidence is emerging that these organisms are also indirectly responsible for several diseases including cancer and rheumatoid arthritis. The oral cavity is home to several million bacteria that can cause two major diseases-periodontitis and caries. The relationship between periodontopathic bacteria and systemic diseases has been explored for several years. The concept of the oral cavity as a source of distant infection has been debated for at least a century. This review will discuss the historic aspects of the development of the focal infection theory, the reasons for its demise, its re-emergence and current status. PMID:24128801

    The development of a new generation of non-vitamin K oral anticoagulants represents a potential breakthrough in the management of patients with thrombotic diseases, disorders and conditions. While a large and growing body of evidence from large-scale clinical trials and registries supports a favorable safety profile, having a means to rapidly reverse their anticoagulant effects represents an unmet need among practicing clinicians. Several targeted reversal agents are currently in development and the early results are promising. Idarucizumab is a monoclonal antibody that can immediately and specifically reverse dabigatran. Andexanet alfa is a recombinant modified factor Xa that can bind and reverse oral and parenteral factor Xa inhibitors, including rivaroxaban, apixaban and edoxaban, and low molecular weight heparin. Aripazine is a small molecule that can reverse the action of factor Xa inhibitors and possibly dabigatran as well through non-covalent binding and charge-charge interactions. PMID:26939028

    Direct oral anticoagulants (DOAC) are recommended for stroke prevention in atrial fibrillation and for the treatment of venous thromboembolism. However, they are associated with hemorrhagic complications. Management of DOAC-induced bleeding remains challenging. Activated or non-activated prothrombin concentrates are proposed, although their efficacy to reverse DOAC is uncertain. Therapeutic options also include antidotes: idarucizumab, antidote for dabigatran, has been approved for use whereas andexanet alpha, antidote for anti-Xa agents, and aripazine, antidote for all DOAC, are under development. Other options include hemodialysis for the treatment of dabigatran-associated bleeding and administration of oral charcoal if recent DOAC ingestion. DOAC plasma concentration measurement is necessary to guide DOAC reversal. We propose an update on DOAC-associated bleeding, integrating the availability of dabigatran antidote and the critical place of DOAC concentration measurements. PMID:27297642

    SUMMARY Oral targeted therapies are increasingly being used to treat cancer. They work by interfering with specific molecules or pathways involved in tumour growth. It is essential that health professionals managing patients taking these drugs have appropriate training and skills. They should be aware of potential adverse effects and drug interactions, and be able to manage toxicities when they occur. Despite the selectivity of these targeted therapies, they still have serious adverse effects including skin reactions, diarrhoea and altered organ function. PMID:26648656

    The development of new disease-modifying drugs (DMD) in relapsing-remitting multiple sclerosis (RRMS), which share the common denominator of oral administration, considerably improves patient expectations in terms of effectiveness, tolerability and treatment adherence compared with currently available drugs. However, the common route of administration of these drugs does not mean that they are equivalent, since the heading of "oral route" encompasses drugs with distinct indications and mechanisms of action, as well as heterogeneous results in terms of efficacy and safety, allowing treatment to be personalized according to the each patient' s characteristics. Currently, four oral DMD are available or in an advanced stage of clinical development: fingolimod, teriflunomide, dimethyl fumarate and laquinimod. In pivotal trials versus placebo, these molecules reduced the annualized rate of exacerbations versus placebo by 54%, 31%, 53% and 23%, respectively, the risk of progression of disability by 31%, 30%, 38% and 36%, and the number of active lesions showing contrast uptake on magnetic resonance imaging by 82%, 80%, 90% and 37%, respectively. Based on the risk/benefit ratio, fingolimod is indicated in patients with suboptimal response to initial DMD or in severe rapidly progressing RRMS, while the remaining drugs can be used as first-line options. Clinical experience with these treatments will provide new data on safety and effectiveness, which will be determinant when establishing therapeutic algorithms. PMID:25732946

    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. PMID:24159754

    Oral health affects older adults and their quality of life. Oral care is reported to have a low priority in nursing care of older adults, and repeated assessments to detect oral health problems are seldom performed. The purpose of this study was to investigate the relationships among level of oral health, nutrition, and oral health-related quality of life (OHRQL) and to identify predictors of OHRQL in Korean older adults. The design was a descriptive, correlational study. The level of oral pain contributed most significantly to OHRQL, followed by nutrition and number of teeth. These three predictor variables explained 46.4% of the variance in OHRQL. Older adults could benefit from oral health care, such as routine screening for oral health and nutritional status. Nurses are at the forefront in providing such services, and it is recommended they integrate oral health care into their routine nursing care plans. PMID:18942537

    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

    To better understand the pharmacokinetics and potential advantages of a levothyroxine oral solution vs. tablets and soft gel capsules.4 randomized, 2-treatment, single-dose (600 mcg levothyroxine), 2-way crossover bioequivalence studies in 84 healthy subjects were analyzed. Samples were collected before dosing and until 48-72 h post-dose to calculate noncompartmental baseline-adjusted pharmacokinetic parameters: maximum concentration, time to maximum concentration, and area-under-the-concentration-time-curve from 0 to 48 h and from 0 to 2 h.Mean pharmacokinetic parameters (±standard deviation) for tablets, capsules and solution, respectively, were: area-under-the-concentration-time-curve from 0 to 2 h (ng*h/mL)=68.4±32.8, 64.4±24.4, 99.1±22.7; area-under-the-concentration-time-curve from 0 to 48 h (ng*h/mL)=1 632±424, 1 752±445, 1 862±439; maximum concentration (ng/mL)=67.6±20.9, 68.0±15.9, 71.4±16.0; time of maximum concentration (hours)=2.25±0.99, 2.38±1.58, 1.96±1.07. Overall rate and extent of exposure were not statistically different between formulations, but a faster onset of absorption for the solution was suggested (greater area-under-the-concentration-time-curve from 0 to 2 h and faster time to maximum concentration by an average of 30 min).Levothyroxine rate and extent of exposure are similar between tested formulations. The solution appears however to reach systemic circulation quicker as dissolution is not needed before absorption starts. The solution's greater early exposure and a faster time to maximal concentration of around 30 min may be of benefit to minimize drug-food interactions and deserves further investigations.

    Background: Oral hygiene is intimated in health of all parts of the body including oral cavity. The understanding of actual practices in keeping the oral heath at standard based on patient's perceptions of oral health care is vital. Understanding the effect of gender on oral health would facilitate the development of successful attitude and behavior modification approach towards sustainable oral health. Purpose of Study: To evaluate awareness regarding oral hygiene practices and exploring gender differences among patients attending for oral prophylaxis. Materials and Methods: A survey was conducted among 250 patients attending the department of periodontology, Maulana Azad institute of dental sciences for oral prophylaxis. A structured questionnaire was used to collect information regarding practices and perception about oral hygiene. Results: Majority of the patients (60.4%) felt that oral hygiene is mandatory for overall health of the body. The use of toothpaste and toothbrush (83.6%) was the most preferred cleaning aid among the study population in the present study. The major constraint for avoiding dental examination was no felt need (41.2%) followed by cost of dental treatment (26.8%) and time constraints (24.0%). Conclusions: Professional plaque removal and regular follow-up combined with oral hygiene instructions to the patients can minimize the level of gingival inflammation and swelling. The poor resources for dental care, common malpractices and nonavailability of professional care are the main barriers in seeking optimum oral hygiene. PMID:25024553

    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. PMID:27051943

    The oral cavity is subject to age related processes such as cellular ageing and immunosenescence. The ageing population bears an increased burden of intraoral pathology. In oral medicine, the majority of presenting patients are in their fifth to seventh decade of life. In this review, we discuss the ageing population's susceptibility to mucosal disorders and the increased prevalence of potentially malignant disorders and oral squamous cell carcinoma, as well as dermatoses including oral lichen planus and immunobullous conditions. We also address the ageing population's susceptibility to oral discomfort and explore salivary secretion, ulceration and the symptoms of oral burning. Finally, we will describe orofacial pain conditions which are more likely encountered in an older population. This update highlights clinical presentations which are more likely to be encountered in the ageing population in a general practice setting and the importance of screening both new and long-term patients.

    Malnutrition affects the oral health and a poor oral health in turn, may lead to malnutrition. This interdependent relationship sees good nutritional health, thus promoting good oral health and vice versa. Malnutrition may alter the homeostasis, which can lead to disease progression of the oral cavity, reduce the resistance to the microbial biofilm and reduce the capacity of tissue healing. It may even affect the development of the oral cavity. Protein-energy malnutrition occurs when there is a deficiency of protein, energy foods or both, which are relative to a body's need. Studies have suggested that enamel hypoplasia, salivary gland hypofunction and saliva compositional changes may be the mechanisms through which the malnutrition is associated with caries, while an altered eruption timing may create a challenge in the analysis of the age specific caries rates. This paper gives an insight on the relationship of the malnutrition and the protein-energy malnutrition with the oral health status. PMID:23449967

    Oral cancer is one of the most common cancers worldwide. Despite of various advancements in the treatment modalities, oral cancer mortalities are more, particularly in developing countries like India. This is mainly due to the delay in diagnosis of oral cancer. Delay in diagnosis greatly reduces prognosis of the treatment and also cause increased morbidity and mortality rates. Early diagnosis plays a key role in effective management of oral cancer. A rapid diagnostic technique can greatly aid in the early diagnosis of oral cancer. Now a day's many adjunctive oral cancer screening techniques are available for the early diagnosis of cancer. Among these, autofluorescence based diagnostic techniques are rapidly emerging as a powerful tool. These techniques are broadly discussed in this review. PMID:26538880

    Oral lichen planus (OLP) and oral lichenoid reaction (OLR) are clinically and histopathologically similar diseases. Whereas OLP is a consequence of T cell mediated autoinflammatory process to a still unknown antigen, OLR might be caused by drugs, dental restorative materials and dental plaque. Pubmed was searched and 24 publications published over the last three years regarding etiology, diagnosis and malignant alteration were included in this study. Patients with OLR who have amalgam fillings near lesions should have them replaced, i.e. when possible they should be referred to patch test, as well as when drug-induced OLR are suspected. OLR lesions induced by drugs should disappear when the offending drug has been discontinued. Histology finding in OLR consists of more eosinophils, plasma cells and granulocytes in comparison to OLP lesions. Furthermore, OLP lesions showed more p53, bcl-2 and COX-2 positivity when compared to OLR. OLP is characterized by infiltration, atrophic epithelium, rete pegs and Max Joseph spaces, while deep infiltration into connective tissue and hyperkeratosis were the criteria for making the diagnosis of OLR. The number of degranulated mastocytes in the reticular layer, as well as the number of capillaries was higher in OLR in comparison to OLP. It seems that OLR are more prone to malignant alteration in comparison to OLP. PMID:27017728

    We report the results of an in-vitro study on autofluorescence from pathologically characterized normal and malignant squamous tissues from the oral cavity. The study involved biopsy samples from 47 patients with oral cancer of which 11 patients had cancer of tongue, 17 of buccal mucosa and 19 of alveolus. The results of excitation and emission spectroscopy at several wavelengths (280 nm less than or equal to (lambda) exless than or equal to 460 nm; 340 nm less than or equal to (lambda) em less than or equal to 520 nm) showed that at (lambda) ex equals 337 nm and 400 nm the mean value for the spectrally integrated fluorescence intensity [(Sigma) (lambda ) IF((lambda) )] from the normal tissue sites was about a factor of 2 larger than that from the malignant tissue sites. At other excitation wavelengths the difference in (Sigma) (lambda ) IF((lambda) ) was not statistically significant. Similarly, for (lambda) em equals 390 nm and 460 nm, the intensity of the 340 nm band of the excitation spectra from normal tissues was observed to be a factor of 2 larger than that from malignant tissues. Analysis of these results suggests that NADH concentration is higher in normal oral tissues compared to the malignant. This contrasts with our earlier observation of an reduced NADH concentration in normal sites of breast tissues vis a vis malignant sites. For the 337 nm excited emission spectra a 10-variable MVLR score (using (Sigma) (lambda ) IF((lambda) ) and normalized intensities at nine wavelengths as input parameters) provided a sensitivity and specificity of 95.7% and 93.1% over the sample size investigated.

    Abstract Objective To explore how birthing and maternity care are understood and valued in a rural community. Design Oral history research. Setting The rural community of Marathon, Ont, with a population of approximately 3500. Participants A purposive selection of mothers, grandmothers, nurses, physicians, and community leaders in the Marathon medical catchment area. Methods Interviews were conducted with a purposive sample, employing an oral history research methodology. Interviews were conducted non-anonymously in order to preserve the identity and personhood of participants. Interview transcripts were edited into short narratives. Oral histories offer perspectives and information not revealed in other quantitative or qualitative research methodologies. Narratives re-personalize and humanize medical research by offering researchers and practitioners the opportunity to bear witness to the personal stories affected through medical decision making. Main findings Eleven stand-alone narratives, published in this issue of Canadian Family Physician, form the project’s findings. Similar to a literary text or short story, they are intended for personal reflection and interpretation by the reader. Presenting the results of these interviews as narratives requires the reader to participate in the research exercise and take part in listening to these women’s voices. The project’s narratives will be accessible to readers from academic and non-academic backgrounds and will interest readers in medicine and allied health professions, medical humanities, community development, gender studies, social anthropology and history, and literature. Conclusion Sharing personal birthing experiences might inspire others to reevaluate and reconsider birthing practices and services in other communities. Where local maternity services are under threat, Marathon’s stories might contribute to understanding the meaning and challenges of local birthing, and the implications of losing

    The ability to generate 3-dimensional volumetric images of the maxillofacial area has allowed surgeons to evaluate anatomy before surgery and plan for the placement of implants in ideal positions. However, the ability to transfer that information to surgical reality has been the most challenging part of implant dentistry. With the advent of computer-assisted surgery, the surgeon may now navigate through the entire implant procedure with extremely high accuracy. A new portable laptop navigated system for oral implantology is discussed as an adjunct for complex implant cases. PMID:16569960

    2016-02-01

    Food allergy is a potentially life-threatening condition with no approved therapies, apart from avoidance and injectable epinephrine for acute allergic reactions. Oral immunotherapy (OIT) is an experimental treatment in which food-allergic patients consume gradually increasing quantities of the food to increase their threshold for allergic reaction. This therapy carries significant risk of allergic reactions. The ability of OIT to desensitize patients to particular foods is well-documented, although the ability to induce tolerance has not been established. This review focuses on recent studies for the treatment of food allergies such as cow's milk, hen's egg, and peanut. PMID:26617227

    Osteosarcoma is the most common primary malignant mesenchymal tumor, accounting for approximately 20% of sarcomas, with 5% incidence in the jaws. They present various clinical and histological aspects as well as variable disease prognosis and outcome. About 50% of all osteosarcomas are osteoblastic, 25% fibroblastic, 25% chondroblastic. Metastasis of osteosarcoma in the oral cavity is rare, and very few cases have been described so far in the literature. This article presents a metastatic case of chondroblastic osteosarcoma in the mandibular right-attached gingiva arising from 4th rib. This case report further suggests that chondroblastic osteosarcoma has poor prognosis. PMID:23293503

  14. Oral cleft prevention program (OCPP)

    PubMed Central

    2012-01-01

    Background Oral clefts are one of the most common birth defects with significant medical, psychosocial, and economic ramifications. Oral clefts have a complex etiology with genetic and environmental risk factors. There are suggestive results for decreased risks of cleft occurrence and recurrence with folic acid supplements taken at preconception and during pregnancy with a stronger evidence for higher than lower doses in preventing recurrence. Yet previous studies have suffered from considerable design limitations particularly non-randomization into treatment. There is also well-documented effectiveness for folic acid in preventing neural tube defect occurrence at 0.4 mg and recurrence with 4 mg. Given the substantial burden of clefting on the individual and the family and the supportive data for the effectiveness of folic acid supplementation as well as its low cost, a randomized clinical trial of the effectiveness of high versus low dose folic acid for prevention of cleft recurrence is warranted. Methods/design This study will assess the effect of 4 mg and 0.4 mg doses of folic acid, taken on a daily basis during preconception and up to 3 months of pregnancy by women who are at risk of having a child with nonsyndromic cleft lip with/without palate (NSCL/P), on the recurrence of NSCL/P. The total sample will include about 6,000 women (that either have NSCL/P or that have at least one child with NSCL/P) randomly assigned to the 4 mg and the 0.4 mg folic acid study groups. The study will also compare the recurrence rates of NSCL/P in the total sample of subjects, as well as the two study groups (4mg, 0.4 mg) to that of a historical control group. The study has been approved by IRBs (ethics committees) of all involved sites. Results will be disseminated through publications and presentations at scientific meetings. Discussion The costs related to oral clefts are high, including long term psychological and socio-economic effects. This study provides an opportunity for

    The purpose of this article was to draw attention to a periimplantitis-like clinical presentation of oral malignancy around dental implants, a phenomenon that may develop without any associated risk factors for oral cancer. Such a benign appearance of oral malignancy may lead to delay in the diagnosis and initiation of ensuing treatment. Therefore, chronic nonhealing inflammatory lesions around dental implants should be considered as highly suspicious. PMID:26803178

    The pharmacokinetics of the aminoglycoside tobramycin was evaluated after oral administration to fed or fasting (15 h) mice. As expected, under normal feeding conditions, oral absorption was negligible; however, fasting induced a dramatic increase in tobramycin bioavailability. The dual-sugar test with lactulose and l-rhamnose confirmed increased small bowel permeability via the paracellular route in fasting animals. When experiments aimed at increasing the oral bioavailability of hydrophilic compounds are performed, timing of fasting should be extremely accurate. PMID:20086144

    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

    Alcohol is a risk factor for oral squamous cell carcinoma. It enhances the permeability of the oral epithelium, acts as a solvent for tobacco carcinogens, induces basal-cell proliferation, and generates free radicals and acetaldehyde, which have the capacity to cause DNA damage. Alcohol-associated malnutrition and immune suppression may further promote carcinogenesis. However, acetaldehyde, the first metabolite of ethanol, is the critical agent by which prolonged and excessive consumption of alcoholic beverages increases the risk of oral squamous cell carcinoma. Alcohol also acts synergistically with the products of tobacco combustion in the pathogenesis of oral squamous cell carcinoma. PMID:23971298

    Introduction The management of oral mucositis is a challenge, due to its complex biological nature. Over the last 10 years, different strategies have been developed for the management of oral mucositis caused by chemotherapy in cancer patients. Material and Methods An exhaustive search was made of the PubMed-Medline, Cochrane Library and Scopus databases, crossing the key words “oral mucositis”, “prevention” and “treatment” with the terms “chemotherapy” and “radiotherapy” by means of the boolean operators “AND” and “NOT”. A total of 268 articles were obtained, of which 96 met the inclusion criteria. Results Several interventions for the prevention of oral mucositis, such as oral hygiene protocols, amifostine, benzidamine, calcium phosphate, cryotherapy and iseganan, among others, were found to yield only limited benefits. Other studies have reported a decrease in the appearance and severity of mucositis with the use of cytoprotectors (sucralfate, oral glutamine, hyaluronic acid), growth factors, topical polyvinylpyrrolidone, and low power laser irradiation. Conclusions Very few interventions of confirmed efficacy are available for the management of oral mucositis due to chemotherapy. However, according to the reviewed literature, the use of palifermin, cryotherapy and low power laser offers benefits, reducing the incidence and severity of oral mucositis – though further studies are needed to confirm the results obtained.

    Oral delivery of insulin may significantly improve the quality of life of diabetes patients who routinely receive insulin by the subcutaneous route. In fact, compared with this administration route, oral delivery of insulin in diabetes treatment offers many advantages: higher patient compliance, rapid hepatic insulinization, and avoidance of peripheral hyperinsulinemia and other adverse effects such as possible hypoglycemia and weight gain. However, the oral delivery of insulin remains a challenge because its oral absorption is limited. The main barriers faced by insulin in the gastrointestinal tract are degradation by proteolytic enzymes and lack of transport across the intestinal epithelium. Several strategies to deliver insulin orally have been proposed, but without much clinical or commercial success. Protein encapsulation into nanoparticles is regarded as a promising alternative to administer insulin orally because they have the ability to promote insulin paracellular or transcellular transport across the intestinal mucosa. In this review, different delivery systems intended to increase the oral bioavailability of insulin will be discussed, with a special focus on nanoparticulate carrier systems, as well as the efforts that pharmaceutical companies are making to bring to the market the first oral delivery system of insulin. The toxicological and safety data of delivery systems, the clinical value and progress of oral insulin delivery, and the future prospects in this research field will be also scrutinized.

    Oral herpes virus infections (OHVIs) are among the most common mucosal disorders encountered by oral health care providers. These infections can affect individuals at any age, from infants to the elderly, and may cause significant pain and dysfunction. Immunosuppressed patients may be at increased risk for serious and potential life-threatening complications caused by OHVIs. Clinicians may have difficulty in diagnosing these infections because they can mimic other conditions of the oral mucosa. This article provides oral health care providers with clinically relevant information regarding etiopathogenesis, diagnosis, and management of OHVIs. PMID:24655522

    The aim of this paper was to assess oral presentation bias at a national level. This was a retrospective cohort study with initial characteristics of the approved protocols extracted from the committee's archives, and follow-up characteristics obtained from a questionnaire mailed to the principal investigators. A representative sample of French research ethics committees (25/48), the only committees legally endorsed for ethical authorisation in biomedical research, were studied. All completed research protocols, which had been approved in 1994 by these committees, were included. Initial characteristics (design, study size, investigator) of completed studies and follow-up information (direction of results, rates of publication and rates of oral presentation) were collected. Complete information on results and their dissemination was available for 248 completed non-confidential protocols. Half of these (49%) were declared as orally presented. The observed ranking for strategies to disseminate results was the following: orally presented and published, published only, neither orally presented nor published and orally presented only. Confirmatory results were more often orally presented, with an adjusted OR of 6.4 (95% CI 2.69 to 15.22). Other associated variables are the following: national/international scope of the study, protocol writer's university status, adverse events and interim analysis. There is a trend to submit or accept confirmatory results for oral presentations: meetings are a biased representation of research, and oral presentation bias could even be higher than publication bias.

    Oral health care in patients undergoing chemotherapy and/or radiation therapy can be complex. Care delivered by a multidisciplinary approach is timely and streamlines the allocation of resources to provide prompt care and to attain favorable outcomes. A hospital dentist, oral and maxillofacial surgeon, and a maxillofacial prosthodontist must be involved early to prevent avoidable oral complications. Prevention and thorough preparation are vital before the start of chemotherapy and radiation therapy. Oral complications must be addressed immediately and, even with the best management, can cause delays and interruption in treatment, with serious consequences for the outcome and prognosis.

    The oral carriage rate of Candida in healthy humans ranges from 40% to 60%. However for a prolonged period, the oral candidal prevalence in humans was documented essentially using data from studies in the West as their prevalence in inhabitants in different regions of the world, including Asia was not known. Yet, recent reports from a number of studies indicate the quality, quantity and prevalence of oral yeasts differ between Asia and other regions for reason that are still unclear.

    The individual oral statement is human story based on experience. The personal experience forms unconsciousness which appears in a form of oral statement by ego that doesn't want to lose existence. Thus, the process which exposes a tormented hearts is the objectification of oneself. Through this step, oral person attains a healing. If this sort of individual oral is accrued, the undeserved personal affairs could be a history. In case of Hansen's disease patient, She could escape from negative understanding about herself and the world. Furthermore, She kept formating her values about meaningful life and future oriented value. Also, She wants to keep a record of her life. She comes to know that what she denied is actually what she should surmount over oral statement. As a result, She could attains a healing for oneself through oral statement. The oral statement made her look into she's problems. Therefore, oral statement is a self-realization. Through this, person could know what the problem is and solution. This research is about only one person, so there is need for more cases and studies. If this sort of individual oral statement is accrued, there could be a curative narration. This can suggest an curative alternative when we suffer from problem of life. The merit of this research is rendering this possibility. PMID:24005645

    In this paper we explore Aboriginal oral traditions that relate to Australian meteorite craters. Using the literature, first-hand ethnographic records and field trip data, we identify oral traditions and artworks associated with four impact sites: Gosses Bluff, Henbury, Liverpool and Wolfe Creek. Oral traditions describe impact origins for Gosses Bluff, Henbury and Wolfe Creek Craters, and non-impact origins for Liverpool Crater, with Henbury and Wolfe Creek stories having both impact and non-impact origins. Three impact sites that are believed to have been formed during human habitation of Australia -- Dalgaranga, Veevers, and Boxhole -- do not have associated oral traditions that are reported in the literature.

    Neurocognitive decline and delirium, frailty, incontinence, falls, hearing and vision impairment, medication compliance and pharmacokinetics, skin breakdown, impaired sleep and rest are regarded as geriatric giants by gerontologists, geriatricians and nursing home staff. As these are all interrelated in the elderly, failure to act on one can impact on the others. However, the implications of poor oral health have for too long been ignored and deserve equal status. Mouth pain can be devastating for the elderly, compound psychosocial problems, frustrate carers and nursing home staff and disrupt family dynamics. As appearance, function and comfort suffer, so may a person's self-esteem and confidence. The contributing factors for poor oral health such as rapid dental decay, acute and chronic periodontal infections and compromised systemic health on a background of a dry mouth, coupled with xerostomia-inducing medications, reduced fine motor function, declining cognition and motivation will not only lead to an increase in both morbidity and mortality but also impact on quality of life.

    2016-01-01

    Oxidative species, including reactive oxygen species (ROS), are components of normal cellular metabolism and are required for intracellular processes as varied as proliferation, signal transduction, and apoptosis. In the situation of chronic oxidative stress, however, ROS contribute to various pathophysiologies and are involved in multiple stages of carcinogenesis. In head and neck cancers specifically, many common risk factors contribute to carcinogenesis via ROS-based mechanisms, including tobacco, areca quid, alcohol, and viruses. Given their widespread influence on the process of carcinogenesis, ROS and their related pathways are attractive targets for intervention. The effects of radiation therapy, a central component of treatment for nearly all head and neck cancers, can also be altered via interfering with oxidative pathways. These pathways are also relevant to the development of many benign oral diseases. In this review, we outline how ROS contribute to pathophysiology with a focus toward head and neck cancers and benign oral diseases, describing potential targets and pathways for intervention that exploit the role of oxidative species in these pathologic processes.

    Oral submucous fibrosis (OSF) is a chronic insidious disease of the oral mucosa, well-recognized as a premalignant condition and commonly found in Southern China. It is primarily caused by the habit of areca nut or gutkha chewing. OSF is believed to be a homeostatic disorder of the extracellular matrix and fibroblast proliferation. The present study demonstrated a novel link between autophagy and OSF. Tissue samples from human OSF showed an overexpression of the autophagy marker microtubule-associated protein 1 light chain 3 using immunohistochemistry and quantitative polymerase chain reaction. With regard to the crucial role of transforming growth factor (TGF)-β in OSF disease, western blot analysis demonstrated that TGF-β signaling was shown to contribute to the activation of autophagy in fibroblasts in vitro; however, a cell apoptosis and MTS assay demonstrated that the suppression of autophagy ameliorated the fibrosis induced by active TGF-β receptor type I signaling, as well as promoted fibroblast apoptosis and suppressed proliferation. Therefore, the present results suggest that autophagy serves a crucial function in OSF. PMID:27168817

    Oral submucous fibrosis (OSF) is a premalignant condition caused by betel chewing. It is very common in Southeast Asia but has started to spread to Europe and North America. OSF can lead to squamous cell carcinoma, a risk that is further increased by concomitant tobacco consumption. OSF is a diagnosis based on clinical symptoms and confirmation by histopathology. Hypovascularity leading to blanching of the oral mucosa, staining of teeth and gingiva, and trismus are major symptoms. Major constituents of betel quid are arecoline from betel nuts and copper, which are responsible for fibroblast dysfunction and fibrosis. A variety of extracellular and intracellular signaling pathways might be involved. Treatment of OSF is difficult, as not many large, randomized controlled trials have been conducted. The principal actions of drug therapy include antifibrotic, anti-inflammatory, and antioxygen radical mechanisms. Potential new drugs are on the horizon. Surgery may be necessary in advanced cases of trismus. Prevention is most important, as no healing can be achieved with available treatments. PMID:25914554

    The mouth is an obvious portal of entry to the body, and oral health reflects and influences general health and well being. Maternal oral health has significant implications for birth outcomes and infant oral health. Maternal periodontal disease, that is, a chronic infection of the gingiva and supporting tooth structures, has been associated with preterm birth, development of preeclampsia, and delivery of a small-for-gestational age infant. Maternal oral flora is transmitted to the newborn infant, and increased cariogenic flora in the mother predisposes the infant to the development of caries. It is intriguing to consider preconception, pregnancy, or intrapartum treatment of oral health conditions as a mechanism to improve women's oral and general health, pregnancy outcomes, and their children's dental health. However, given the relationship between oral health and general health, oral health care should be a goal in its own right for all individuals. Regardless of the potential for improved oral health to improve pregnancy outcomes, public policies that support comprehensive dental services for vulnerable women of childbearing age should be expanded so that their own oral and general health is safeguarded and their children's risk of caries is reduced. Oral health promotion should include education of women and their health care providers ways to prevent oral disease from occurring, and referral for dental services when disease is present.

    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.

    The use of oral anticancer drugs has shown a steady increase. Most patients prefer anticancer oral therapy to intravenous treatment primarily for the convenience of a home-based therapy, although they require that the efficacy of oral therapy must be equivalent and toxicity not superior than those expected with the intravenous treatment. A better patient compliance, drug tolerability, convenience and possible better efficacy for oral therapy as compared to intravenous emerge as the major reasons to use oral anticancer agents among oncologists. Inter- and intra-individual pharmacokinetic variations in the bioavailability of oral anticancer drugs may be more relevant than for intravenous agents. Compliance is particularly important for oral therapy because it determines the dose-intensity of the treatment and ultimately treatment efficacy and toxicity. Patient stands as the most important determinant of compliance. Possible measures for an active and safe administration of oral therapy include a careful preliminary medical evaluation and selection of patients based on possible barriers to an adequate compliance, pharmacologic issues, patient-focused education, an improvement of the accessibility to healthcare service, as well as the development of home-care nursing symptom-focused interventions. Current evidences show similar quality of life profile between oral and intravenous treatments, although anticancer oral therapy seems to be more convenient in terms of administration and reduced time lost for work or other activities. Regarding cost-effectiveness, current evidences are in favor of oral therapy, mainly due to reduced need of visits and/or day in hospital for the administration of the drug and/or the management of adverse events.

Materials and Methods: Total of 50 samples were selected for the study and were categorized into five groups and 10 samples in each group as Group I-oral leukoplakia (OL), Group II-oral lichen planus (OLP), Group III-oral submucous fibrosis (OSMF), Group IV-oral squamous cell carcinoma (OSCC) and Group V-normal oral mucosa (NOM) as control group. All the samples were assessed for the expression of E-cad by immunohistochemical study. Results: Upon assessing the expression of E-cad in OL, OSMF, OLP and OSCC, as majority of the samples with OSCC (90%), OL (80%), OLP (70%) and OSMF (60%) showed mild to moderate expression of E-cad staining, which was suggestive of reduction in dysplastic cells on comparison to NOM cells. This difference in expression and variation of E-cad upon comparison with normal mucosa was statistically significant (P < 0.001). Conclusion: There is significant (P < 0.001) variation of expression of E-cad with the histopathological dysplasia of the oral precancerous lesions and conditions, and the tumor differentiation of the oral cancers. However, there was no correlation of the degree of loss of expression of E-cad with the degree of dysplasia or the tumor differentiation of oral cancers. We conclude with our study that, there is a variation in the expression of E-cad but its value as a prognostic marker is questionable. PMID:26430364

    Background: Squamous cell carcinoma (SCC) is the third most common cause of oral morbidity in India despite the numerous advances made in the treatment protocol. Aim: To compare the cytomorphometric changes of oral mucosal cells in normal subjects (Group I) with that of tobacco users without any lesion (Group II), tobacco users with oral leukoplakia (Group III), and tobacco users with oral SCC (Group IV) through a semi-automated image analysis system. Materials and Methods: Oral mucosal cells collected from study subjects (n = 100) stained using rapid Papanicolaou stain. Photomicrograph of 50 nonoverlapping cells captured at 50× magnification with a digital image capture system. Cytomorphometric analysis of cells in the captured images was performed with Image-Pro image analysis software. Image analysis was performed to obtain cell diameter (CD), cytoplasmic area (CyA), nuclear diameter (ND), nuclear area (NA), and nuclear-to-cytoplasmic ratio. These values were statistically compared among the groups using one-way analysis of variance (ANOVA) and Mann-Whitney U test. Results: The ND, NA, and nuclear-to-cytoplasmic ratio values were found to be increased in the samples collected from leukoplakia and oral SCC. The CD and CyA decreased compared to the normal mucosa in oral SCC samples. Conclusion: The cytomorphometric changes observed in samples from oral SCC and oral leukoplakia were consistent with the current diagnostic features. Hence, the semi-automated cytomorphometric analysis of oral mucosal cells can be used as an objective adjunct diagnostic tool in the diagnosis of these lesions. PMID:26811574

    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

  5. Oral microbial habitat a dynamic entity.

    PubMed

    Faran Ali, Syed Muhammad; Tanwir, Farzeen

    2012-01-01

    Oral microbial habitat is composed of wide variety of species. These species play a significant role in maintaining the well being of the oral cavity by contributing in various ways. However the proper functioning of these oral microbes can be detrimental for the human oral cavity if the conditions are not suitable such as redox potential (Eh), pH of a site, the activity of the host defenses, and the presence of antimicrobial agents. The oral microbial community represents the best-characterized group associated with the human host. There are strong correlations between the qualitative composition of the oral microbiota and clinically healthy or diseased states. Amongst the bacteria of more than 700 species now identified within the human oral microbiota, it is the streptococci that are numerically predominant. Interactions between mucosal surfaces and microbial microbiota are key to host defense, health, and disease. These surfaces are exposed to high numbers of microbes and must be capable of distinguishing between those that are beneficial or avirulent and those that will invade and cause disease. Our understanding of the mechanisms involved in these discriminatory processes has recently begun to expand as new studies bring to light the importance of epithelial cells and novel immune cell subsets such as T(h)17 T cells in these processes. In this review article we have tried to find out the factors responsible for maintaining oral microbial habitat intact and the reasons which cause changes in its composition. PMID:25737863

    Voriconazole (VRCZ), a broad-spectrum triazole, is served in two dosage forms-injection and oral. VRCZ is difference dosage of oral and intravenous administration writing a medical package insert in Japan. 6 mg/kg intravenous injection (IV) twice daily for first day as initial loading dose, followed by 3-4 mg/kg IV twice daily between meals is recommended. 300 mg orally twice daily for first day as initial loading dose, followed by 150-200 mg orally twice daily between meals is recommended. Patients weighing over 40 kg, 200 mg orally twice daily between meals is recommended. Patients weighing under 40 kg, 100 mg orally twice daily between meals is recommended, increase to 150 mg twice daily if inadequate response. This study evaluated VRCZ trough concentration and oral dosage in the 23 cases which administered VRCZ to analysis for TDM in Aichi University Hospital. Spearman rank correlation coefficient was calculated to examine relationships among variables. The level of statistical significance was set at p=0.05. All data were analyzed and processed on JMP 8 (SAS Institute Japan). There was a significant positive correlation between VRCZ trough concentration and dose/weight (r=0.47 p<0.05). In this result, VRCZ oral dosage is appropriate to administer dose/weight (mg/kg) twice a day as same as IV. PMID:25566590

  14. Underlying skills of oral and silent reading.

    PubMed

    van den Boer, Madelon; van Bergen, Elsje; de Jong, Peter F

    2014-12-01

    Many studies have examined reading and reading development. The majority of these studies, however, focused on oral reading rather than on the more dominant silent reading mode. Similarly, it is common practice to assess oral reading abilities rather than silent reading abilities in schools and in diagnosis of reading impairments. More important, insights gained through examinations of oral reading tend to be generalized to silent reading. In the current study, we examined whether such generalizations are justified. We directly compared oral and silent reading fluency by examining whether these reading modes relate to the same underlying skills. In total, 132 fourth graders read words, sentences, and text orally, and 123 classmates read the same material silently. As underlying skills, we considered phonological awareness, rapid naming, and visual attention span. All skills correlated significantly with both reading modes. Phonological awareness contributed equally to oral and silent reading. Rapid naming, however, correlated more strongly with oral reading than with silent reading. Visual attention span correlated equally strongly with both reading modes but showed a significant unique contribution only to silent reading. In short, we showed that oral and silent reading indeed are fairly similar reading modes, based on the relations with reading-related cognitive skills. However, we also found differences that warrant caution in generalizing findings across reading modes. PMID:25173643

    High level of periodontal problems of dental caries are frequently observed in mentally handicapped children. This group of patients presents various problems when they face dental treatments. Identification of such population and providing them affordable oral health care is the new concept. A systematic method for identification and screening of persons with mental retardation has been developed and is being followed. Cost and fear are the most commonly cited barriers to dental care. Physical or mental may lead to deterioration in self-care, and oral care state have a low priority. Risk factors are inter-related and are often barriers to oral health. With advancements in today's world sufficient information and support is available for each and every individual to lead a healthy life which include the access to the oral health care. Factors such as fear, anxiety and dental phobia plays a vital role in acceptance of dental care and also the delaying of dental care. Lack of knowledge of oral and dental disease, awareness or oral need, oral side-effects of medication and organization of dental services are highlighted in the literature. All health personnel should receive training to support the concept of primary oral health care. Training about dealing with such mentally handicapped people should be addressed urgently among the health professionals. PMID:25738098

    Since the initial observations of oral bacteria within dental plaque by van Leeuwenhoek using his primitive microscopes in 1680, an event that is generally recognized as the advent of oral microbiological investigation, oral microbiology has gone through phases of “reductionism” and “holism”. From the small beginnings of the Miller and Black period, in which microbiologists followed Koch's postulates, took the reductionist approach to try to study the complex oral microbial community by analyzing individual species; to the modern era when oral researchers embrace “holism” or “system thinking”, adopt new concepts such as interspecies interaction, microbial community, biofilms, poly-microbial diseases, oral microbiological knowledge has burgeoned and our ability to identify the resident organisms in dental plaque and decipher the interactions between key components has rapidly increased, such knowledge has greatly changed our view of the oral microbial flora, provided invaluable insight into the etiology of dental and periodontal diseases, opened the door to new approaches and techniques for developing new therapeutic and preventive tools for combating oral poly-microbial diseases.

    Previous studies have used cryotherapy for the treatment of oral precancers including oral leukoplakia (OL) and oral verrucous hyperplasia (OVH) as well as oral cancers including oral verrucous carcinoma (OVC) and oral squamous cell carcinoma (OSCC). Cryotherapy is a method that locally destroys lesional tissues by freezing in situ. It can be carried out by either an "open" or a "closed" system. Lesional tissues are destroyed mainly through disruption of cell membrane, cellular dehydration, enzyme and protein damage, cell swelling and rupture, thermal shock injury to cells, damage to vasculature, and immune-mediated cytotoxicity. Cryotherapy is used frequently for the treatment of OL lesions with promising results. It can also be used to treat OVH and OVC lesions. Because OVH and OVC lesions are usually fungating and bulky, a combination therapy of shave excision and cryotherapy is needed to achieve a complete regression of the lesion. OSCCs have also been treated by cryotherapy. However, cryotherapy is not the main-stream treatment modality for OSCCs. Cryotherapy seems suitable for treatment of thin or relatively thick plaque-typed lesions such as OL lesions. By careful selection of patients, cryotherapy is a simple, safe, easy, conservative, and acceptable treatment modality for certain benign oral lesions and oral precancers. PMID:24560447

    2002-01-01

    The delivery of proteins has gained momentum with the development of biotechnology sector that provided large-scale availability of therapeutic proteins. The availability is mostly due to the advances in recombinant DNA technology. The low oral bioavailability, however, continues to be a problem for several proteins because of their large molecular size, low permeation through biological membranes, and susceptibility to molecular changes in both biological and physical environments. The demand for effective delivery of proteins by the oral route has brought a tremendous thrust in recent years both in the scope and complexity of drug delivery technology. The important therapeutic proteins and peptides being explored for oral delivery include insulin, calcitonin, interferons, human growth hormone, glucagons, gonadotropin-releasing hormones, enkephalins, vaccines, enzymes, hormone analogs, and enzyme inhibitors. This article reviews the progress in oral delivery of these proteins, provides comments on the strategies to improve their oral bioavailability, and highlights their current market trends.

    Dental sleep medicine is a rapidly growing field that is in close and direct interaction with sleep medicine and comprises many aspects of human health. As a result, dentists who encounter sleep health and sleep disorders may work with clinicians from many other disciplines and specialties. The main sleep and oral health issues that are covered in this review are obstructive sleep apnea, chronic mouth breathing, sleep-related gastroesophageal reflux, and sleep bruxism. In addition, edentulism and its impact on sleep disorders are discussed. Improving sleep quality and sleep characteristics, oral health, and oral function involves both pathophysiology and disease management. The multiple interactions between oral health and sleep underscore the need for an interdisciplinary clinical team to manage oral health-related sleep disorders that are commonly seen in dental practice.

    Although corticosteroids have immunosuppressive, anti-inflammatory, and anti-allergic effects, allergic reactions are rare. We report a case involving a 52-year-old-female with acute urticaria caused by oral methylprednisolone. The patient had experienced aspirin-exacerbated respiratory disease (AERD) for 13 years with frequent asthma exacerbations. Symptoms of asthma exacerbations improved with short-term treatments of systemic steroids, including methylprednisolone or deflazacort, which had been well tolerated. However, the current admission was prompted by the development of acute generalized urticaria following the oral ingestion of methylprednisolone (8 mg) for relief of symptoms. An oral provocation test with 4 mg oral methylprednisolone led to generalized urticaria 20 minutes later, confirming the causal association. This is the first report of acute urticaria caused by oral methylprednisolone in a patient with AERD. PMID:21966609
