Full Text Available Abstract Background Counterfeit oral artesunate has been a major public health problem in mainland SE Asia, impeding malaria control. A countrywide stratified random survey was performed to determine the availability and quality of oral artesunate in pharmacies and outlets (shops selling medicines in the Lao PDR (Laos. Methods In 2003, 'mystery' shoppers were asked to buy artesunate tablets from 180 outlets in 12 of the 18 Lao provinces. Outlets were selected using stratified random sampling by investigators not involved in sampling. Samples were analysed for packaging characteristics, by the Fast Red Dye test, high-performance liquid chromatography (HPLC, mass spectrometry (MS, X-ray diffractometry and pollen analysis. Results Of 180 outlets sampled, 25 (13.9% sold oral artesunate. Outlets selling artesunate were more commonly found in the more malarious southern Laos. Of the 25 outlets, 22 (88%; 95%CI 68–97% sold counterfeit artesunate, as defined by packaging and chemistry. No artesunate was detected in the counterfeits by any of the chemical analysis techniques and analysis of the packaging demonstrated seven different counterfeit types. There was complete agreement between the Fast Red dye test, HPLC and MS analysis. A wide variety of wrong active ingredients were found by MS. Of great concern, 4/27 (14.8% fakes contained detectable amounts of artemisinin (0.26–115.7 mg/tablet. Conclusion This random survey confirms results from previous convenience surveys that counterfeit artesunate is a severe public health problem. The presence of artemisinin in counterfeits may encourage malaria resistance to artemisinin derivatives. With increasing accessibility of artemisinin-derivative combination therapy (ACT in Laos, the removal of artesunate monotherapy from pharmacies may be an effective intervention.
Purpose: The study was carried out to evaluate the quality of artesunate tablets sold in retail and wholesale pharmacies in Kumasi, Ghana. In particular, the study sought to ascertain the presence or otherwise of counterfeit artesunate tablets in Kumasi. Method: Artesunate tablets were purchased from pharmacies in Kumasi ...

A randomized pilot study to compare the safety and efficacy of artesunate suppositories (15 mg/kg/day for three days) versus oral artesunate (6 mg/kg/day for three days), both in combination with mefloquine (25 mg/kg), was conducted in 52 Thai children with uncomplicated multidrug-resistant falciparum malaria. Forty-five patients (87%) had a full 28-day follow-up in the hospital to assess efficacy and exclude reinfection. Mean [range] times to fever clearance of the two groups were similar (42 hr [15-104] versus 42 hr [6-119]). Artesunate suppositories resulted in significantly longer times to achieve 50% and 90% reductions of the initial parasite counts (17 and 26 hr versus 9 and 15 hr; P suppositories group (42 hr [14-93] versus 35 hr [16-69]), but the difference was not significant. The cure rates by days 28 were not significantly different, 92% for artesunate suppository-treated patients and 100% for oral artesunate-treated patients. Both drug regimens are safe and effective. Further studies are needed to characterize the pharmacokinetic properties and the optimum regimen of artesunate suppositories for the treatment of severe malaria.

Full Text Available Artemisinin-based combination therapies decrease Plasmodium gametocyte carriage. However, the role of artesunate in monotherapy in vivo, the mechanisms involved, and the utility of gametocyte carriage as a potential tool for the surveillance of antimalarial resistance are poorly understood. In 2010–2011, we conducted an open-label, prospective efficacy study of artesunate as monotherapy in children 1–10 years of age with uncomplicated falciparum malaria in Bougoula-Hameau, Mali. Standard oral doses of artesunate were administered for 7 days and patients were followed up for 28 days. The data were compared to a similar study conducted in 2002–2004. Of 100 children enrolled in the 2010–2011 study, 92 were analyzed and compared to 217 children enrolled in the 2002–2004 study. The proportion of gametocyte carriers was unchanged at the end of treatment (23% at baseline vs. 24% on day 7, p = 1.0 and did not significantly decline until day 21 of follow-up (23% vs. 6%, p = 0.003. The mean gametocyte density at inclusion remained unchanged at the end of treatment (12 gametocytes/μL vs. 16 gametocytes/μL, p = 0.6. Overall, 46% of the 71 initial non-carriers had gametocytes detected by day 7. Similar results were found in the 2002–2004 study. In both studies, although gametocyte carriage significantly decreased by the end of the 28-day follow-up, artesunate did not clear mature gametocytes during treatment and did not prevent the appearance of new stage V gametocytes as assessed by light microscopy. Baseline gametocyte carriage was significantly higher 6 years after the deployment of artemisinin-based combination therapies in this setting.

Full Text Available Abstract Background The population pharmacokinetics of artesunate (AS and its active metabolite dihydroartemisinin (DHA were studied in healthy subjects receiving single- or multiple-dosing of AS orally either in combination with pyronaridine (PYR or as a monotherapy with or without food. Methods Data from 118 concentration-time profiles arising from 91 healthy Korean subjects were pooled from four Phase I clinical studies. Subjects received 2-5 mg/kg of single- and multiple-dosing of oral AS either in combination with PYR or as a monotherapy with or without food. Plasma AS and DHA were measured simultaneously using a validated liquid chromatography- mass spectrometric method with a lower limit of quantification of 1 ng/mL for both AS and DHA. Nonlinear mixed-effect modelling was used to obtain the pharmacokinetic and variability (inter-individual and residual variability parameter estimates. Results A novel parent-metabolite pharmacokinetic model consisting of a dosing compartment, a central compartment for AS, a central compartment and a peripheral compartment for DHA was developed. AS and DHA data were modelled simultaneously assuming stoichiometric conversion to DHA. AS was rapidly absorbed with a population estimate of absorption rate constant (Ka of 3.85 h-1. The population estimates of apparent clearance (CL/F and volume of distribution (V2/F for AS were 1190 L/h with 36.2% inter-individual variability (IIV and 1210 L with 57.4% IIV, respectively. For DHA, the population estimates of apparent clearance (CLM/F and central volume of distribution (V3/F were 93.7 L/h with 28% IIV and 97.1 L with 30% IIV, respectively. The population estimates of apparent inter-compartmental clearance (Q/F and peripheral volume of distribution (V4/F for DHA were 5.74 L/h and 18.5 L, respectively. Intake of high-fat and high-caloric meal prior to the drug administration resulted in 84% reduction in Ka. Body weight impacted CLM/F, such that a unit change in
Full Text Available Abstract Background Currently, population pharmacokinetic (PK studies of anti-malarial drugs are designed primarily by the logistical and ethical constraints of taking blood samples from patients, and the statistical models that are fitted to the data are not formally considered. This could lead to imprecise estimates of the target PK parameters, and/or designs insufficient to estimate all of the parameters. Optimal design methodology has been developed to determine blood sampling schedules that will yield precise parameter estimates within the practical constraints of sampling the study populations. In this work optimal design methods were used to determine sampling designs for typical future population PK studies of dihydroartemisinin, the principal biologically active metabolite of oral artesunate. Methods Optimal designs were derived using freely available software and were based on appropriate structural PK models from an analysis of data or the literature and key sampling constraints identified in a questionnaire sent to active malaria researchers (3-4 samples per patient, at least 15 minutes between samples. The derived optimal designs were then evaluated via simulation-estimation. Results The derived optimal sampling windows were 17 to 29 minutes, 30 to 57 minutes, 2.5 to 3.7 hours and 5.8 to 6.6 hours for non-pregnant adults; 16 to 29 minutes, 31 minutes to 1 hour, 2.0 to 3.4 hours and 5.5 to 6.6 hours for designs with non-pregnant adults and children and 35 to 59 minutes, 1.2 to 3.4 hours, 3.4 to 4.9 hours and 6.0 to 8.0 hours for pregnant women. The optimal designs resulted in acceptable precision of the PK parameters. Conclusions The proposed sampling designs in this paper are robust and efficient and should be considered in future PK studies of oral artesunate where only three or four blood samples can be collected.

The ineffectiveness of artesunate and amodiaquine tablets in malaria treatment remains a health burden to WHO and governments of malaria-endemic countries, including Ghana. The proliferation of illegitimate anti-malarial drugs and its use by patients is of primary concern to international and local drug regulatory agencies because such drugs are known to contribute to the development of the malaria-resistant parasites in humans. No data exist on quality of these drugs in the fishing village communities in Ghana although the villagers are likely users of such drugs. A pilot study on the quality of anti-malarial tablets in circulation during the major fishing season at a malarious fishing village located along the coast of Tema in southern Ghana was determined. Blisterpacks of anti-malarial tablets were randomly sampled. The International Pharmacopoeia and Global Pharma Health Fund Minilab protocols were used to assess the quality of anti-malarial tablets per blisterpacks allegedly manufactured by Guilin Pharmaceutical Co Ltd, China (GPCL) and Letap Pharmaceuticals Ltd, Ghana (LPL) and sold in chemical sales outlets at Kpone-on-Sea. Ferric chloride and cobaltous thiocyanate tests confirmed the presence of active ingredients in the tablets. A confirmatory test for the active ingredient was achieved with artesunate (ICRS1409) and amodiaquine (ICRS0209) reference standards. A high performance liquid chromatography analysis confirmed the amount of artesunate found in tablets. Based on the International Pharmacopoeia acceptable range of 96/98 to 102% for genuine artesunate per tablet, 10% [relative standard deviation (RSD): 3.2%] of field-selected artesunate blisterpack per tablets manufactured by GPCL, and 50% (RSD: 5.1%) of a similar package per tablet by LPL, passed the titrimetric test. However, 100% (RSD: 2.2%) of amodiaquine blisterpack per tablet by GPCL were found to be within the International Pharmacopeia acceptable range of 90 to 110% for genuine amodiaquine in

Plasmodium falciparum resistance to artemisinins by delayed parasite clearance is present in Southeast Asia. Scant data on parasite clearance after artemisinins are available from Africa, where transmission is high, burden is greatest, and artemisinin use is being scaled up. Children 1–10 years of age with uncomplicated malaria were treated with 7 days of artesunate and followed for 28 days. Blood smears were done every 8 hours until negative by light microscopy. Results were compared with a similar study conducted in the same village in 2002–2004. The polymerase chain reaction-corrected cure rate was 100%, identical to 2002–2004. By 24 hours after treatment initiation, 37.0% of participants had cleared parasitemia, compared with 31.9% in 2002–2004 (P = 0.5). The median parasite clearance time was 32 hours. Only one participant still had parasites at 48 hours and no participant presented parasitemia at 72 hours. Artesunate was highly efficacious, with no evidence of delayed parasite clearance. We provide baseline surveillance data for the emergence or dissemination of P. falciparum resistance in sub-Saharan Africa. PMID:22764287

Malaria affects about forty percent of the world’s population. Annually more than 1.5 million fatalities due to malaria occur and parasite resistance to existing antimalarial drugs such as mefloquine has already reached disturbingly high levels in South-East Asia and on the African continent. Consequently, there is a dire need for new drugs or formulations in the prophylaxis and treatment of malaria. Artesunate, an artemisinin derivative, represents a new category of antimalarials that is eff...

The World Health Organization (WHO) recommends that people with uncomplicated Plasmodium falciparum malaria are treated using Artemisinin-based Combination Therapy (ACT). ACT combines three-days of a short-acting artemisinin derivative with a longer-acting antimalarial which has a different mode of action. Pyronaridine has been reported as an effective antimalarial over two decades of use in parts of Asia, and is currently being evaluated as a partner drug for artesunate. To evaluate the efficacy and safety of artesunate-pyronaridine compared to alternative ACTs for treating people with uncomplicated P. falciparum malaria. We searched the Cochrane Infectious Diseases Group Specialized Register; Cochrane Central Register of Controlled Trials (CENTRAL), published in The Cochrane Library; MEDLINE; EMBASE; LILACS; ClinicalTrials.gov; the metaRegister of Controlled Trials (mRCT); and the WHO International Clinical Trials Search Portal up to 16 January 2014. We searched reference lists and conference abstracts, and contacted experts for information about ongoing and unpublished trials. Randomized controlled trials of artesunate-pyronaridine versus other ACTs in adults and children with uncomplicated P. falciparum malaria.For the safety analysis, we also included adverse events data from trials comparing any treatment regimen containing pyronaridine with regimens not containing pyronaridine. Two authors independently assessed trial eligibility and risk of bias, and extracted data. We combined dichotomous data using risk ratios (RR) and continuous data using mean differences (MD), and presented all results with a 95% confidence interval (CI). We used the GRADE approach to assess the quality of evidence. We included six randomized controlled trials enrolling 3718 children and adults.

Full Text Available Objective: To evaluate the anti-inflammatory and antipyretic potentials of artesunate in albino wistar mice and rats respectively. Methods: For the anti-inflammatory activity, artesunate (5 mg/kg was administered orally against egg albumin- and xylene-induced inflammation in mice using ibuprofen (50 mg/kg as standard drug. To assess antipyretic activity, artesunate (5 mg/kg was administered orally against amphetamine- and 2, 4-dinitrophenol-induced pyrexia in rats using ibuprofen (15 mg/ kg as standard drug. Results: The result showed that artesunate significantly (P < 0.001–0.010 reduced inflammation induced by egg albumin and xylene in a time-dependent manner. It also significantly (P < 0.001–0.050 and time-dependently reduced pyrexia induced by amphetamine and 2, 4-dinitrophenol. These reductions were similar to those produced by the standard drug ibuprofen, and thereby demonstrating that artesunate possesses antiinflammatory and antipyretic activities. Conclusions: These results further support the rationale for the use of artesunate in the treatment of malaria, a disease characterized by fever and inflammation and open up possibilities of its usefulness in other inflammatory and feverish diseases.

Full Text Available Abstract Background Intravenous (IV artesunate is the treatment of choice for severe malaria. In Europe, however, no GMP-manufactured product is available and treatment data in European travellers are scarce. Fortunately, artesunate became available in the Netherlands and Belgium through a named patient programme. This is the largest case series of artesunate treated patients with severe malaria in Europe. Methods Hospitalized patients treated with IV artesunate between November 2007 and December 2010 in the Netherlands and Belgium were retrospectively evaluated. Patient characteristics, treatment and clinical outcome were recorded on a standardized form and mortality, parasite clearance times and the occurrence of adverse events were evaluated. Results Of the 68 treated patients, including 55 with severe malaria, two patients died (2/55 = 3.6%. The mean time to 50% parasite clearance (PCT50, 90% and 99% were 4.4 hours (3.9 - 5.2, 14.8 hours (13.0 - 17.2, and 29.5 hours (25.9 - 34.4 respectively. Artesunate was well tolerated. However, an unusual form of haemolytic anaemia was observed in seven patients. The relationship with artesunate remains uncertain. Conclusions Data from the named patient programme demonstrate that IV artesunate is effective and well-tolerated in European travellers lacking immunity. However, increased attention needs to be paid to the possible development of haemolytic anaemia 2-3 weeks after start of treatment. Treatment of IV artesunate should be limited to the period that IV treatment is required and should be followed by a full oral course of an appropriate anti-malarial drug.
Full Text Available Abstract Background In many malaria-endemic countries, increasing resistance may soon compromise the efficacy of sulphadoxine-pyrimethamine (SP for intermittent preventative treatment (IPT of malaria in pregnancy. Artemisinin-based IPT regimens represent a promising potential alternative to SP. Pharmacokinetic and safety data supporting the use of artemisinin derivatives in pregnancy are urgently needed. Methods Subjects included pregnant women with asymptomatic falciparum parasitaemia between 22-26 weeks (n = 13 or 32-36 weeks gestation (n = 13, the same women at three months postpartum, and 25 non-pregnant parasitaemic controls. All subjects received 200 mg orally administered AS. Plasma total and free levels of AS and its active metabolite DHA were determined using a validated LC-MS method. Non-compartmental pharmacokinetic analysis was performed using standard methods. Results All pregnant women delivered live babies. The median birth weight was 3025 grams [range 2130, 3620]; 2 of 26 babies had birth weights less than 2500 grams. Rates of parasite clearance by 12 hours post-dose were high and comparable among the groups. Rapid elimination of AS was observed in all three groups. The 90% CI for the pregnancy:postpartum ratio of geometric means for total and free AUC fell within the pre-specified 0.66 - 1.50 therapeutic equivalence interval. However, more pronounced pharmacokinetic differences were observed between the pregnancy and control subjects, with the 90% CI for the pregnancy:control ratio of geometric means for both total 0.68 (90% CI 0.57-0.81 and free AUC 0.78 (90% CI 0.63-0.95 not fully contained within the 0.66 - 1.50 interval. All subjects cleared parasites rapidly, and there was no difference in the percentage of women who were parasitaemic 12 hours after dosing. Conclusions A single dose of orally administered AS was found to be both effective and without adverse effects in this study of second and third trimester pregnant women

Lyme borreliosis is associated with memory deficits. While this may be related to cerebral infection by Borrelia bacteria, it may also be caused by concomitant co-infection by Babesia protozoa. The anti-malarial artemisinin-derivative artesunate has been shown to be effective against a number of Babesia species and to have efficacy against human cerebral malaria. We hypothesised that concomitant administration of artesunate in Lyme borreliosis patients would help alleviate the severity of self-reported short-term memory impairment. This hypothesis was tested in a small pilot study in which patients were treated with both an intravenous antibiotic and oral artesunate (20mg four times per day); treatment was associated with a reduction in the severity of short-term memory difficulties (P≃0.08). In light of these findings, we recommend that a formal randomised, placebo-controlled study be carried out. Copyright © 2017 Elsevier Ltd. All rights reserved.

Drug treatment of severe malaria must be rapidly effective. Suppositories may be valuable for childhood malaria when circumstances prevent oral or parenteral therapy. We compared artesunate suppositories (n = 41; 8 to 16 mg/kg of body weight at 0 and 12 h and then daily) with intramuscular (i.m.) artemether (n = 38; 3.2 mg/kg at 0 h and then 1.6 mg/kg daily) in an open-label, randomized trial with children with severe Plasmodium falciparum malaria in Papua New Guinea (PNG). Parasite density and temperature were measured every 6 h for ≥72 h. Primary endpoints included times to 50% and 90% parasite clearance (PCT50 and PCT90) and the time to per os status. In a subset of 29 patients, plasma levels of artemether, artesunate, and their common active metabolite dihydroartemisinin were measured during the first 12 h. One suppository-treated patient with multiple complications died within 2 h of admission, but the remaining 78 recovered uneventfully. Compared to the artemether-treated children, those receiving artesunate suppositories had a significantly earlier mean PCT50 (9.1 versus 13.8 h; P = 0.008) and PCT90 (15.6 versus 20.4 h; P = 0.011). Mean time to per os status was similar for each group. Plasma concentrations of primary drug plus active metabolite were significantly higher in the artesunate suppository group at 2 h postdose. The earlier initial fall in parasitemia with artesunate is clinically advantageous and mirrors higher initial plasma concentrations of active drug/metabolite. In severely ill children with malaria in PNG, artesunate suppositories were at least as effective as i.m. artemether and may, therefore, be useful in settings where parenteral therapy cannot be given.

Compared to the artemether-treated children, those receiving artesunate suppositories had a significantly earlier mean PCT50 (9.1 versus 13.8 h; P = 0.008) and PCT90 (15.6 versus 20.4 h; P = 0.011). Mean time to per os status was similar for each group. Plasma concentrations of primary drug plus active metabolite were significantly higher in the artesunate suppository group at 2 h postdose. The earlier initial fall in parasitemia with artesunate is clinically advantageous and mirrors higher initial plasma concentrations of active drug/metabolite. In severely ill children with malaria in PNG, artesunate suppositories were at least as effective as i.m. artemether and may, therefore, be useful in settings where parenteral therapy cannot be given.

Despite the important role of the antimalarial artesunate and its active metabolite dihydroartemisinin (DHA) in malaria treatment efforts, there are limited data on the pharmacokinetics of these agents in pediatric patients. This study evaluated the effects of body size and gender on the pharmacokinetics of artesunate-DHA using data from pediatric and adult malaria patients. Nonlinear mixed-effects modeling was used to obtain a base model consisting of first-order artesunate absorption and one-compartment models for artesunate and for DHA. Various methods of incorporating effects of body size descriptors on clearance and volume parameters were tested. An allometric scaling model for weight and a linear body surface area (BSA) model were deemed optimal. The apparent clearance and volume of distribution of DHA obtained with the allometric scaling model, normalized to a 38-kg patient, were 63.5 liters/h and 65.1 liters, respectively. Estimates for the linear BSA model were similar. The 95% confidence intervals for the estimated gender effects on clearance and volume parameters for artesunate fell outside the predefined no-relevant-clinical-effect interval of 0.75 to 1.25. However, the effect of gender on apparent DHA clearance was almost entirely contained within this interval, suggesting a lack of an influence of gender on this parameter. Overall, the pharmacokinetics of artesunate and DHA following oral artesunate administration can be described for pediatric patients using either an allometric scaling or linear BSA model. Both models predict that, for a given artesunate dose in mg/kg of body weight, younger children are expected to have lower DHA exposure than older children or adults.

Background Intra-rectal artesunate has been developed as a potentially life-saving treatment of severe malaria in rural village settings where administration of parenteral antimalarial drugs is not possible. We studied the population pharmacokinetics of intra-rectal artesunate and the relationship with parasitological responses in patients with moderately severe falciparum malaria. Methods and Findings Adults and children in Africa and Southeast Asia with moderately severe malaria were recruited in two Phase II studies (12 adults from Southeast Asia and 11 children from Africa) with intensive sampling protocols, and three Phase III studies (44 children from Southeast Asia, and 86 children and 26 adults from Africa) with sparse sampling. All patients received 10 mg/kg artesunate as a single intra-rectal dose of suppositories. Venous blood samples were taken during a period of 24 h following dosing. Plasma artesunate and dihydroartemisinin (DHA, the main biologically active metabolite) concentrations were measured by high-performance liquid chromatography with electrochemical detection. The pharmacokinetic properties of DHA were determined using nonlinear mixed-effects modelling. Artesunate is rapidly hydrolysed in vivo to DHA, and this contributes the majority of antimalarial activity. For DHA, a one-compartment model assuming complete conversion from artesunate and first-order appearance and elimination kinetics gave the best fit to the data. The mean population estimate of apparent clearance (CL/F) was 2.64 (l/kg/h) with 66% inter-individual variability. The apparent volume of distribution (V/F) was 2.75 (l/kg) with 96% inter-individual variability. The estimated DHA population mean elimination half-life was 43 min. Gender was associated with increased mean CL/F by 1.14 (95% CI: 0.36–1.92) (l/kg/h) for a male compared with a female, and weight was positively associated with V/F. Larger V/Fs were observed for the patients requiring early rescue treatment compared

As part of new drug development initiatives in Thailand, a new tablet formulation of dihydroartemisinin (DHA, an antimalarial drug) has been developed. Our previous bioequivalence study indicated that the new and reference DHA formulations were well tolerated; however, a significant decrease in hemoglobin was detected after a single 200-mg oral dose. To explore further, a clinical study with an emphasis on hematological parameters was conducted. A single-center, randomized, single-blind, cross-over clinical study was conducted in 18 healthy volunteers with a dosage of 300 mg daily for 2 days. Artesunate was used as a comparator. Adverse events were monitored and laboratory parameters on study Days 0, 2, 5, and 7 post drug administrations were analyzed. Eighteen volunteers completed both rounds of the study. Both drugs were well tolerated. All adverse events were mild. Significant decrease in hemoglobin compared to baseline was detected for both drugs 7 days after administration (DHA: 0.48 g/dl, p = 0.007; artesunate 0.38 g/dl, p = 0.001). Transient bone marrow suppression was evidenced by reduction of reticulocytes with a lowest number on study Day 5 (artesunate 75% reduction in reticulocyte count; DHA 47%, p < 0.001 for both drugs compared to baseline). The present study confirmed our previous finding on significant decrease in hemoglobin. Artesunate appeared to have more negative effects on the numbers of reticulocytes and white blood cells than DHA. Systemic laboratory and toxicity profiles presented in this study may be used as a framework for future clinical studies of artemisinin and its derivatives.

Full Text Available Background/Aim. Adolescents are vulnerable group in term of acquisition of oral health-related knowledge, habits and attitudes. That is why the aim of this study was to investigate the associations between dental status, dental anxiety and oral health-related behavior and oral healthrelated quality of life as captured by Oral Impacts on Daily Performances (OIDP index. Methods. This crosssectional survey included representative sample of 404 adolescents (15 years old, randomly recruited from high schools in Belgrade, Serbia. The adolescents were interviewed using Serbian versions of eight-item OIDP index, Hiroshima University Dental Behavior Inventory (HUDBI and modified Corah’s Dental Anxiety Scale (MDAS. Three previously trained and calibrated dentists examined the subjects in the classrooms to determine the oral health status of adolescents [the Decayed, missing, filled teeth (DMFT index and visual signs of gingivitis]. Results. At least one oral impact was reported in 49.50% of adolescents. Most frequently, oral health problems affected eating (26.73%, tooth cleaning (27.47% and sleep and relaxation (16.83%. In comparison with adolescents without oral impacts, the adolescents with at least one oral impact reported, had higher DMFT score, more often reported problems with bleeding gums, usage of hard toothbrush, worries about the color of their teeth and seeing the dentist because of the symptoms. Logistic regression showed that dental anxiety (MDAS score, dental behavior (HUDBI score and worrying about the color of the teeth significantly affected OIDP score. Conclusion. Oral healthrelated quality of life among adolescents was affected by their behavior and dental anxiety levels. Implementing public health policies that target adolescents with poor oral health or bad habits might be helpful in improving their oral health-related quality of life.

The aim of this work was to assess the association among oral health, general health, and quality of life (QoL). The Oral Health Impact Profile (OHIP-49) and the RAND-36 were distributed amongst 118 psychology freshmen. Additionally, two single items self-rated general health (SRGH) and self-rated oral health (SROH) - were administered. Kruskal-Wallis and Mann-Whitney U-tests were used to evaluate differences between SRGH and SROH categories, regarding OHIP subscale scores and RAND subscale scores. More than 75% of the subjects rated their oral and general health as good. Mean OHIP scores and RAND scores indicated a relatively good oral- and general health-related QoL respectively. The correlation between oral and general health was weak. Significant differences were found between SRGH categories regarding RAND subscale scores, except for the 'role emotional' and 'mental health' subscales. Significant differences were also found between SROH categories regarding OHIP subscale scores, except for the 'psychological disability' subscale. However, no significant differences were found between SRGH categories regarding OHIP subscale scores, or between SROH categories regarding RAND subscale scores. The findings suggest that oral health, general health, and QoL have different determinants. Furthermore, oral health and general health appear to be mostly unrelated in this seemingly healthy population. It is proposed that if no apparent disease is present, oral and general health must be regarded as separate constructs.

The present study aimed to investigate the prevalence of oral microbiota (Candida species (spp.), Streptococcus mutans, and Lactobacilli) in patients with multibracket (MB) appliances in relation to the quality of oral hygiene. Saliva and plaque samples were collected from three groups of 25 patients each (good oral hygiene (GOH), poor oral hygiene (POH), and poor oral hygiene with white spot lesions (POH/WSL)). Counts of colony forming units (CFU) of the investigated oral microbiota were compared using Chi-square and Mann-Whitney U tests. Both saliva and plaque samples showed a high prevalence of Candida spp. in all patients (saliva: 73.4 %, plaque: 60.9 %). The main Candida species was C. albicans. The salivary CFU of Candida spp. in the GOH group was significantly lower than that in the POH group (p = 0.045) and POH/WSL group (p = 0.011). S. mutans was found in the saliva and plaque samples of all patients. Lactobacilli were found in the saliva samples of all patients and in 90.7 % of the plaque samples. In the saliva samples, the CFU of Lactobacilli were more numerous in the POH and POH/WSL groups than in the GOH group (p = 0.047). The investigated sample of patients showed a high carriage of oral Candida spp. Patients with WSL formation during MB appliance treatment exhibited higher counts of Candida and Lactobacilli compared with patients with good oral hygiene. Independent of oral hygiene quality, S. mutans was detected in all patients.

Although suppositories of artemisinin derivatives may be a valuable option for treatment of malaria in children when circumstances prevent oral and parenteral therapy, few confirmatory data have been published. We assessed the safety and efficacy of rectal artesunate in 47 children ages 5 to 10 years with uncomplicated malaria acquired in a hyperendemic area of Papua New Guinea. Thirty were symptomatic and had Plasmodium falciparum parasitemia >2000/microl (Group 1), 12 had and either a parasitemia suppositories were well-tolerated. After 24 h only one child (from Group 1) had persistent parasitemia, and only one (from Group 3) had not defervesced. These two children received intramuscular quinine and recovered uneventfully. Three Group 2 children redeveloped fever and tachycardia at 24 h, but each responded to simple supportive measures and remained aparasitemic. Intrarectal artesunate is safe, effective initial treatment for uncomplicated malaria in children. A transient fever spike can sometimes occur after parasite clearance. We recommend that children with uncomplicated malaria receive two doses of > or =10 mg/kg rectal artesunate within the first 24 h.

This study examines whether oral health-related quality of life (OHRQoL) is associated with malnutrition risk in the elderly. A cross-sectional study was designed using a representative sample of Spaniards over 65 years old. Data on sociodemographics and oral health status were gathered by interview and examination. Oral health-related quality of life was evaluated using the Geriatric Oral Health Assessment Index (GOHAI), and malnutrition risk using the Mini Nutritional Assessment (MNA). The final sample included 2,860 elderly, 41.7 percent males and 58.3 percent females, with a mean age of 73.7 +/- 6.8 years. Mean GOHAI score was 52.1 +/- 7.2, with 70.7 percent of the sample needing oral health care according to this index. The mean MNA score was 24.0 +/- 3.31; 3.5 percent of the elderly were malnourished, 31.5 percent were at risk of malnutrition, and 65.0 percent were considered adequately nourished. A strong association was found between mean GOHAI and MNA scores.

Full Text Available Participation in diagnostic microbiology internal and external quality control (QC processes is good laboratory practice and an essential component of a quality management system. However, no QC scheme for diagnostic oral microbiology existed until 2009 when the Clinical Oral Microbiology (COMB Network was created. At the European Oral Microbiology Workshop in 2008, 12 laboratories processing clinical oral microbiological samples were identified. All these were recruited to participate into the study and six laboratories from six European countries completed both the online survey and the first QC round. Three additional laboratories participated in the second round. Based on the survey, European oral microbiology laboratories process a significant (mean per laboratory 4,135 number of diagnostic samples from the oral cavity annually. A majority of the laboratories did not participate in any internal or external QC programme and nearly half of the laboratories did not have standard operating procedures for the tests they performed. In both QC rounds, there was a large variation in the results, interpretation and reporting of antibiotic susceptibility testing among the laboratories. In conclusion, the results of this study demonstrate the need for harmonisation of laboratory processing methods and interpretation of results for oral microbiology specimens. The QC rounds highlighted the value of external QC in evaluating the efficacy and safety of processes, materials and methods used in the laboratory. The use of standardised methods is also a prerequisite for multi-centre epidemiological studies that can provide important information on emerging microbes and trends in anti-microbial susceptibility for empirical prescribing in oro-facial infections.

Method: A retrospective study was performed on all routine oral surgery referrals received between 2014 and 2015 at both Halmstad Hospital and Växjö Hospital. A total of 1,891 referral letters were assessed for their quality against a predetermined checklist of basic requirements of a satisfactory referral. The referrals were also categorized according to if it was sent by a male, female, private dental service, or the Swedish Public Dental Health service. Results: A diagnosis was missing in 30% of all referrals. Radiographs and information about previous radiographic examinations were not included in 10% of the referrals. Of those referrals that included radiographs, only around half were deemed adequate for diagnostic purposes. The presenting complaint was missing in 40% of all referrals. Current medical history was absent in 40% and current medication was omitted in 60% of the referrals. Information about tobacco use was only included in 10% of all referrals. Overall, female referrers performed better than male colleagues. Private referrals more regularly included information about diagnosis, previous treatment, and current medication. On the other hand, referrals from the public dental health service more frequently included radiographs, tobacco use, and current medical history. Conclusion: There is plenty of room for improving the standards of oral surgery referrals. We suggest that future electronic referral systems should only allow for submission once all of the essential information has been considered.

To assess the impact of oral hygiene of preschool children and parental attitude on children's oral health-related quality of life (OHRQoL). In this cross-sectional study, 396 children of Shiraz kindergartens were selected by a randomized cluster sampling. Children's oral hygiene was assessed using the Simplified Debris Index (DI-S) and a self-made questionnaire about oral hygiene habits. Children's OHRQoL was evaluated by the Farsi version of Early Childhood Oral Health Impact Scale (F-ECOHIS). The effect of oral hygiene determinants on OHRQoL was measured using Pearson and Spearman correlation, independent-sample t-test and anova. Children's mean DI-S and F-ECOHIS scores were 1.19 (± 0.77) and 19.36 (±8.42), respectively. Only 75% of the children had their teeth brushed once a day or more, and in 28%, toothbrushing had started before 2 years of age. DI-S values (P children. Children's OHRQoL was also significantly associated with parents' attitude towards the importance of brushing deciduous teeth (P = 0.002). Oral health status of preschool children in Shiraz was less than optimal and had a significant impact on their OHRQoL. Therefore, improvement of children's OHRQoL could be achieved by improving their home dental care. Strategies promoting parental attitude about the importance of children's toothbrushing may significantly influence children's oral hygiene and are highly recommended. © 2015 John Wiley & Sons A/S.

In recent years the quality of life of patients is very important in monitoring the treatment and therapeutic procedure success. It has become a significant factor in assessing the therapeutic procedure accomplishment, and for the first time the patient alone can access the success of the respective therapy. Cancer of the oral cavity is one of the most common cancers of the head and neck, and is one of the ten most common causes of death in the world. In the majority of cases, cancer of the oral cavity is detected in an advanced stage when therapeutic options are reduced, and the prognosis is much worse. Cancer of the oral cavity is 10 times more common in men. Assessment of quality of life should be an indicator of the multidisciplinary treatment success and it should point to areas in which the affected person requires support. To examine the quality of life of patients with oral cavity cancer. The study was conducted at the Clinic of Maxillofacial Surgery of the Clinical Center University of Sarajevo (CCUS), through a survey on patients with verified oral cavity cancer, questionnaire related to socio-demographic characteristics of the patients and the University of Washington Quality of Life Questionnaire (UW-QOL). The results were included in the database and statistically processed in the SPSS program, 19.0 version for Windows. Afterwards, the results were thoroughly analyzed and documented, presented in absolute numbers and statistical values using statistical indicators in simple and understandable tables and figures. The study results showed that out of the total score of 100, the median value of quality of life of patients with oral cavity cancer, for the physical health component in the definition of quality was M=69.75 ±29.12 and for social-emotional health M=65.11 ± 27.47. This could be considered as satisfactory quality of life, in the sphere above half of the rating scale, although both values significantly deviate from the UW-QOL scale norm

Artesunate and Amodiaquine combination is one of the first line drugs for the treatment of uncomplicated malaria. To prevent treatment failures and emergence of resistant strains of the Plasmodium parasite, patients are entreated to comply with treatment regimens. Thus fixed dose tablet formulations came as a relieve to patients, ensuring proper compliance as the number of tablets to be taken was reduced. It is therefore important to develop simple methods of assay for these formulations to ensure that quality drugs are available and to prevent resistance to these drugs. This thesis describes Ultraviolet (UV) and High Performance Liquid Chromatographic (HPLC) methods of assay for Artesunate (AS) and Amodiaduine Hydrochloride (AMQ) in fixed dose tablet formulations. The UV absorption spectroscopy was used to establish a wavelength of maximum absorption and the Beer’s plot generated. At 339nm, Amodiaquine Hydrochloride was assayed accurately in methanol with a high r"2 value of 0.998, an intra and inter day precision of Relative Standard Deviation (RSD) of 1.52% and 1.86% respectively. The Beer’s plot was obeyed in a concentration range of 3.5 - 24.8(µg/mL). The limit of detection and limit of quantification was 1.23(µg/mL) and 3.73(µg/mL) respectively. However the UV method could not be used to assay AS simultaneously with AMQ. A mobile phase of 60% acetonitrile and 40% of 0.05% trifluoroacetic acid, flow rate of 1ml/min, wavelength of detection of 225nm and a C_1_8 stationary phase are the parameters for the HPLC method. The r"2 for the HPLC method was 0.996 and 0.995 for Amodiaquine hydrochloride and Artesunate respectively. The intra and inter day precision were 1.07% and 1.42% respectively. The limit of detection and limit of quantification were 0.015%w/v and 0.0465%w/v for Amodiaquine hydrochloride and 0.054%w/v and 0.019%w/v for Artesunate respectively. The concentration ranges were 0.01 - 0.16%w/v for Amodiaquine hydrochloride and 0.01 – 0.2%w/v for

The aim of this study was to assess the prevalence of oral mucosal lesions and their impact on oral health-related quality of life (OHRQoL) in children aged 5 years. A sample of 1118 children from Pelotas' birth cohort, born in 2004 (response rate of 85.8%), were selected to participate in the study. Data were collected using a questionnaire applied to mothers and from the oral examinations of the children. OML were identified by type, site, and size. Early Childhood Oral Health Impact Scale (ECOHIS) was used to assess caregivers' perception on children's OHRQoL. Descriptive, bivariate, and multivariate Poisson regression analyses were carried out, considering the impact on OHRQoL (total ECOHIS score) as the outcome. The prevalence of the OML was 30.1% (95% CI 27.5-32.9). Ulcers were the more prevalent type of lesion (29.4%), and the most affected site was the gums (31.0%). In bivariate analysis, there was a positive association between the presence of OML and OHRQoL impact measured by the following: mean overall score of ECOHIS (P children with OML presented higher impact on OHRQoL [rate ratio (RR) 1.38 95% CI 1.11; 1.72] comparing with their counterparts. Analyzing specific domains, children with OML also presented higher impact on children symptoms (RR 1.46 95% CI 1.20; 1.66) and family functional (RR 3.14 95% CI 1.59; 6.22) domains. Almost one-third of children presented with oral mucosal lesions, and these lesions impaired children's oral health-related quality of life. © 2015 John Wiley & Sons A/S.

We can improve our understanding of how patients cope with oral squamous cell carcinoma (SCC) by making a comparison with their processes of coping and those used in other conditions. We have therefore compared quality of life (QoL), severity of symptoms, coping strategies, and factors that influence coping between patients with oral SCC and those with oral lichen planus. We asked 104 patients with oral SCC and 51 with oral lichen planus to complete questionnaires about their coping strategies, social support, locus of control, spirituality, QoL, and severity of symptoms. The outcome was that patients with oral SCC were far more likely to resort to coping strategies such as depressive coping, distraction, and self-motivation. The groups also differed regarding QoL and severity of symptoms. Patients with oral SCC had a poorer QoL and higher depression scores, whereas patients with oral lichen planus had better scores in the social support and spirituality categories. Patients with oral SCC generally had more distress than those with oral lichen planus. Not only did the former resort to depressive coping strategies, but they also had poorer QoL and higher values for depression. For the patients with oral lichen planus, social support and spirituality were protective, whereas they were associated with distress by patients with oral SCC.

Background To assess the impact of oral mucosa lesions on quality of life related to oral health (QLROH) and additionally to establish whether the etiopathogenicy of oral lesion is associated to the degree of QLROH impact. Material and Methods In this cross-sectional study performed on a non-probability sample of 247 consecutively patients attending the oral medicine and pathology clinic the Spanish version of Oral Health Impact Profile-49 questionnaire (OHIP-49-mx) was applied. Responses were recorded on Likert-type scale whose values ranged from 0 (never) to 4 (always). Values greater than the 50 percentile (median) were considered as indicative of poor quality of life. All patients were orally examined and diagnosed. In accordance to their etiopathogenicy 6 study groups were formed: 4 corresponded to MIND classification for diseases (Metabolic, Inflammatory, Neoplastic, and Development groups), with ≥2 diseases and no-lesion group. To identify possible differences of OHIP-49 values between study groups an ANOVA (one factor) parametric and a chi square tests were performed (SPSS®20.0). Results The OHIP-49-mx values were higher than the 50 percentile (established at 39) in metabolic, inflammatory, development, and ≥2 diseases groups, suggesting that this type of oral lesions negatively impact the quality of life. ≥2 diseasesgroup followed by metabolic and inflammatory diseases group (p 0.001) depicted worst quality of life. Functional limitation (p 0.003), pain, physical inability (p 0.001) and psychological disabilities dimensions exhibited greater values in all groups. Conclusions Injured oral mucosa negatively impacts quality of life, specifically functional limitation, physical inability and psychological disabilities could lead to social isolation.To our knowledge, this is the first time that an association between QLROH and the etiopathogenicy of oral mucosal diseases is established.

Oral lichen planus (OLP) can seriously affect the quality of life of patients because it has a strong impact on social relations, psychological status and daily activities. To study the quality of life using the Oral Health Impact Profile (OHIP-49) (validated Spanish version) in patients with OLP. A total of 74 patients with a minimum age of 18 years who had lichen planus were recruited into the study, along with 74 'healthy' subjects matched by sex and age who acted as control. Both groups completed the OHIP-49. Higher scores were obtained on the OHIP-49 index in patients with OLP for all the subgroups and for the overall total than in the control group. Furthermore, there were statistically significant differences in the items concerning psychological discomfort, social disability and handicap in patients with OLP. The study shows that the quality of life in patients with OLP is reduced and that patient-centred measures should be considered in the management of patients with OLP.

Full Text Available Abstract Background Mefloquine and artesunate combination therapy is the recommended first-line treatment for uncomplicated malaria throughout much of south-east Asia. Concerns have been raised about the potential central nervous system (CNS effects of both drug components and there are no detailed reports in very young children. Methods Children, aged between three months and five years, with acute uncomplicated Plasmodium falciparum malaria were randomized to either 7 days of artesunate monotherapy or the same schedule of artesunate plus mefloquine on day 7 and 8. Neurological testing targeting coordination and behaviour was carried out at day 0, 7, 9, 10, 14 and 28. Non-febrile healthy control children from the same population were tested on days 0, 7, 14 and 28. Results From December 1994 to July 1997, 91 children with uncomplicated P. falciparum, 45 treated with artesunate monotherapy, 46 treated with mefloquine and artesunate combination therapy and 36 non-febrile controls, underwent neurological testing. Malaria and fever had a significant negative impact on testing performance. By contrast, the anti-malarial treatments were not associated with worsening performances in the various components of the test. Artesunate and mefloquine do not appear to have a significant influence on coordination and behaviour. Children treated with mefloquine were significantly less likely to suffer recurrent malaria infection during follow-up compared to those treated with artesunate alone (P = 0.033. Conclusion In keeping with the results of randomized controlled trials in adults, mefloquine was not associated with a decrease in specific items of neurological performance. Likewise, children treated with artesunate did not perform significantly differently to control children. This study does not exclude subtle or rare treatment CNS effects of artesunate or mefloquine. Treatment of acute uncomplicated malaria results in a significant improvement on items of
Full Text Available Abstract Background Pharmacokinetic (PK data on amodiaquine (AQ and artesunate (AS are limited in children, an important risk group for malaria. The aim of this study was to evaluate the PK properties of a newly developed and registered fixed dose combination (FDC of artesunate and amodiaquine. Methods A prospective population pharmacokinetic study of AS and AQ was conducted in children aged six months to five years. Participants were randomized to receive the new artesunate and amodiaquine FDC or the same drugs given in separate tablets. Children were divided into two groups of 70 (35 in each treatment arm to evaluate the pharmacokinetic properties of AS and AQ, respectively. Population pharmacokinetic models for dihydroartemisinin (DHA and desethylamodiaquine (DeAq, the principal pharmacologically active metabolites of AS and AQ, respectively, and total artemisinin anti-malarial activity, defined as the sum of the molar equivalent plasma concentrations of DHA and artesunate, were constructed using the non-linear mixed effects approach. Relative bioavailability between products was compared by estimating the ratios (and 95% CI between the areas under the plasma concentration-time curves (AUC. Results The two regimens had similar PK properties in young children with acute malaria. The ratio of loose formulation to fixed co-formulation AUCs, was estimated as 1.043 (95% CI: 0.956 to 1.138 for DeAq. For DHA and total anti-malarial activity AUCs were estimated to be the same. Artesunate was rapidly absorbed, hydrolysed to DHA, and eliminated. Plasma concentrations were significantly higher following the first dose, when patients were acutely ill, than after subsequent doses when patients were usually afebrile and clinically improved. Amodiaquine was converted rapidly to DeAq, which was then eliminated with an estimated median (range elimination half-life of 9 (7 to 12 days. Efficacy was similar in the two treatments groups, with cure rates of 0

To assess the impact of oral health on quality of life in elderly Brazilians and to evaluate its association with clinical oral health measures and socioeconomic and general health factors. Cross-sectional study. Population-based cohort study on health, well-being, and aging. Eight hundred fifty-seven participants representing 588,384 community-dwelling elderly adults from the city of São Paulo, Brazil. Self-perceived impact of oral health on quality of life was measured using the Geriatric Oral Health Assessment Index (GOHAI), with scores categorized as good, moderate, or poor, indicating low, moderate, and high degrees of negative impact on quality of life, respectively. Nearly half of the individuals had good GOHAI scores (44.7% of overall sample, 45.9% of dentate participants, and 43.4% of edentulous participants). In the overall sample, those with poor self-rated general health and a need for dental prostheses were more likely to have poor and moderate GOHAI scores. Individuals with depression were significantly more likely to have poor GOHAI scores. No socioeconomic variables were related to the outcome, except self-perception of sufficient income, which was a protective factor against a poor GOHAI score in dentate participants. Moderate and high degrees of negative impact of oral health on quality of life were associated with general health and clinical oral health measures, independent of socioeconomic factors. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

To compare the oral health-related quality of life (OHRQoL) and sleep quality of subjects with and without sleep bruxism (SB). Participants of both genders were assigned as bruxers (n = 30, age 21-45 years) and non-bruxers (n = 30, age 24-40 years). SB was clinically diagnosed and confirmed with an electromyography/electrocardiograph portable device (Bruxoff). The OHRQoL was assessed using the Oral Health Impact Profile (OHIP-14). The sleep quality was determined using the Pittsburg Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) questionnaires. OHIP-14, PSQI, and ESS data were analyzed by one-way ANOVA, considering a significance level of 5%. Bruxers had worse OHRQoL (mean = 16.43) than controls (mean = 4.1), with an effect size (ES) of 1.58. Moreover, SB volunteers showed the highest PSQI scores (mean = 7.07; ES = 0.82) and excessive daytime sleepiness (mean = 10.33; ES = 0.65), compared to non-bruxers (means = 4.7 and 7.8, respectively). SB may be associated with a negative impact on OHRQoL and sleep quality. Determining that SB may have a marked role in OHRQoL and sleep quality is important for dental professionals establish proper multifactorial management, and understand patient-related psychosocial aspects.

A thermostable suppository of artesunate (artesunic acid) has been developed. In Gabon, 12 children with Plasmodium falciparum malaria received two administrations of this suppository in a 4-hr interval. Parasitemia and fever were then measured and the plasma levels of artesunate and its active metabolite, dihydroartemisinin, were determined by means of a reversed phase high-pressure liquid chromatography method using reductive electrochemical detection. Substantial parasite clearance (97-100%) was noted 24 hr after the beginning of the treatment and body temperature had returned to normal. Absorption, metabolism, and elimination of artesunate were rapid. Mean values of maximum plasma levels (Cmax) and maximum concentration peak times (tmax) were evaluated. The Cmax of dihydroartemisinin (0.18 +/- 0.10 microg/ml [mean +/- SE]) was higher than the Cmax of artesunate (0.09 +/- 0.04 microg/ml) and the tmax of dihydroartemisinin (1.13 +/- 0.58 hr) was higher than the tmax of artesunate (0.58 +/- 0.19 hr). Plasma levels 30 min after the second suppository administration were not consistently higher than those found 30 min after the first administration.

Ectodermal dysplasia (ED) is a rare congenital hereditary disorder among a group of syndromes characterized by abnormalities of ectodermic structures. The purpose of this report is to compare the oral health-related quality of life (OHRQoL) before and after complete oral rehabilitation of a five-year-old boy with ED. Delivery of upper and lower dentures resulted in immediate improvement of the child's OHRQoL. Although ED affects patients physically and emotionally, the early oral rehabilitation of young patients is crucial to improve their social interaction and restore their speech and masticatory function.

Artesunate (AST), the most widely used artemisnin derivative, has poor aqueous solubility and suffers from low oral bioavailability (~40%). Under these conditions, nanoparticles with controlled and sustained released properties can be a suitable solution for improving its biopharmaceuticals properties. This work reports the preparation and characterization of auto-assembled chitosan/lecithin nanoparticles loaded with AST and AST complexed with β-cyclodextrin (β-CD) to boost its antimalarial activity. The nanoparticles prepared by direct injection of lecithin alcoholic solution into chitosan/water solution have shown the particle size distribution below 300 nm. Drug entrapment efficiency was found to be maximum (90%) for nanoparticles containing 100 mg of AST. Transmission electron microscopy images show spherical shape with contrasted corona (chitosan) surrounded by a lipidic core (lecithin + isopropyl myristate). Differential scanning calorimeter thermograms demonstrated the presence of drug in drug-loaded nanoparticles along with the disappearance of decomposition exotherm suggesting the increased physical stability of drug in prepared formulations. Negligible changes in the characteristic peaks of drug in Fourier-transform infrared spectra indicated the absence of any interaction among the various components entrapped in the nanoparticle formulation. In vitro drug release behavior was found to be influenced by pH value. Increased in vivo antimalarial activity in terms of less mean percent parasitemia was observed in infected Plasmodium berghei mice after the oral administration of all the prepared nanoparticle formulations.

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

To investigate the prevalence and severity of oral health-related quality of life in patients treated with removable partial dentures at a publicly-funded dental hospital. The association between patients' demographic profiles, denture-related, variables and oral health-related quality of life was also investigated. A questionnaire was designed to investigate the use and satisfaction of removable partial dentures, and oral health-related quality of life of removable partial denture wearers using the Oral Health Impact Profile-14. The questionnaire was administered to 740 randomly-selected patients who received removable partial dentures during 2005-2008. The response rate was 31.35%. Non-parametric tests and a logistic regression model were used to analyze the association between denture-related variables and oral health-related quality of life. A question on symptoms unrelated to dentures was also analyzed. The Oral Health Impact Profile-14 prevalence calculated was 43.1%. The removable partial denture experience and frequency of use was inversely associated with Oral Health Impact Profile-14 scores. Metal-based removable partial dentures were associated with lower Oral Health Impact Profile prevalence and severity scores. No significant association was found between demographic profile, circumstance for provision of removable partial dentures and Oral Health Impact Profile-14 score. The participants of this study indicated that perceived denture performance, removable partial dentures material, experience, and frequency of use are associated with oral health-related quality of life. © 2012 Blackwell Publishing Asia Pty Ltd.

This study aims to examine if older adults living in poverty and from minority racial/ethnic groups experienced disproportionately high rates of poor oral health outcomes measured by oral health quality of life (OHQOL) and number of permanent teeth. Cross-sectional analysis of 2,745 community-dwelling adults aged ≥65 years from the National Health and Nutrition Examination Survey (NHANES) 2005-2008. Oral health outcomes were assessed by questionnaire using the NHANES-Oral Health Impact Profile for OHQOL and standardized examination for dentition. Logistic and linear regression analyses were used to determine the association between oral health outcomes and predictors of interest. All analyses were weighted to account for complex survey sampling methods. Both poverty and minority race/ethnicity were significantly associated with poor oral health outcomes in OHQOL and number of permanent teeth. Distribution of scores for each OHQOL domain varied by minority racial/ethnic group. Oral health disparities persist in older adults living in poverty and among those from minority racial/ethnic groups. The racial/ethnic variation in OHQOL domains should be further examined to develop interventions to improve the oral health of these groups. © 2014 American Association of Public Health Dentistry.

Full Text Available Plasmodium falciparum resistance to artemisinins, the first line treatment for malaria worldwide, has been reported in western Cambodia. Resistance is characterized by significantly delayed clearance of parasites following artemisinin treatment. Artemisinin resistance has not previously been reported in Myanmar, which has the highest falciparum malaria burden among Southeast Asian countries.A non-randomized, single-arm, open-label clinical trial of artesunate monotherapy (4 mg/kg daily for seven days was conducted in adults with acute blood-smear positive P. falciparum malaria in Kawthaung, southern Myanmar. Parasite density was measured every 12 hours until two consecutive negative smears were obtained. Participants were followed weekly at the study clinic for three additional weeks. Co-primary endpoints included parasite clearance time (the time required for complete clearance of initial parasitemia, parasite clearance half-life (the time required for parasitemia to decrease by 50% based on the linear portion of the parasite clearance slope, and detectable parasitemia 72 hours after commencement of artesunate treatment. Drug pharmacokinetics were measured to rule out delayed clearance due to suboptimal drug levels.The median (range parasite clearance half-life and time were 4.8 (2.1-9.7 and 60 (24-96 hours, respectively. The frequency distributions of parasite clearance half-life and time were bimodal, with very slow parasite clearance characteristic of the slowest-clearing Cambodian parasites (half-life longer than 6.2 hours in approximately 1/3 of infections. Fourteen of 52 participants (26.9% had a measurable parasitemia 72 hours after initiating artesunate treatment. Parasite clearance was not associated with drug pharmacokinetics.A subset of P. falciparum infections in southern Myanmar displayed markedly delayed clearance following artemisinin treatment, suggesting either emergence of artemisinin resistance in southern Myanmar or spread

To evaluate the effects of artesunate on organ injury and dysfunction associated with hemorrhagic shock (HS) in the rat. HS is still a common cause of death in severely injured patients and is characterized by impairment of organ perfusion, systemic inflammatory response, and multiple organ failure. There is no specific therapy that reduces organ injury/dysfunction. Artesunate exhibits pharmacological actions beyond its antimalarial activity, such as anticancer, antiviral, and anti-inflammatory effects. Rats were submitted to HS. Mean arterial pressure was reduced to 30 mm Hg for 90 minutes, followed by resuscitation. Rats were randomly treated with artesunate (2.4 or 4.8 mg/kg i.v.) or vehicle upon resuscitation. Four hours later, parameters of organ injury and dysfunction were assessed. Artesunate attenuated the multiple organ injury and dysfunction caused by HS. Pathway analysis of RNA sequencing provided good evidence to support an effect of artesunate on the Akt-survival pathway, leading to downregulation of interleukin-1 receptor-associated kinase 1. Using Western blot analysis, we confirmed that treatment of HS rats with artesunate enhanced the phosphorylation (activation) of Protein kinase B (Akt) and endothelial nitric oxide synthase and the phosphorylation (inhibition) of glycogen synthase kinase-3β (GSK-3β). Moreover, artesunate attenuated the HS-induced activation of nuclear factor kappa B and reduced the expression of proinflammatory proteins (inducible nitric oxide synthase, tumor necrosis factor-α, and interleukin 6). Artesunate attenuated the organ injury/dysfunction associated with HS by a mechanism that involves the activation of the Akt-endothelial nitric oxide synthase survival pathway, and the inhibition of glycogen synthase kinase-3β and nuclear factor kappa B. A phase II clinical trial evaluating the effects of good manufacturing practice-artesunate in patients with trauma and severe hemorrhage is planned.
Full Text Available Introduction: Over the past few decades mankind has been mainly affected with chronic noncommunicable diseases, which led to compromised quality of life. Common dental diseases come under same categories that are largely social and behavioral in origin. Health-related quality of life helps us address the limitations of traditional clinical indicators of health. Aim: To measure the impact of oral health on quality of life among patients visiting dental teaching hospitals and private clinics in Bangalore city using oral health-related quality of life (OHQoL - U.K index. Materials and Methods: A total of 1200 individuals who are above 16-year of age were selected through stratified cluster random sampling technique for this study. Data were collected using OHQoL-U.K instrument. Results: Most of the subjects (78% perceived their oral health as impacting their quality of life. Many participants perceived their oral health had positive impact on life quality through enhancing their smile, appearance, speech. But 44.9% and 28.5% of respondents said their oral health has a negative impact on quality of life because of breath odor and finance respectively. Subjects are belonging to lower socioeconomic background, women and older adults (>45 years perceived their oral health has a negative impact on quality of life compared to subjects from higher social class, men and young adults. Conclusion: Oral health has more impact on physical and functional aspects rather than on social and psychological domains.

Full Text Available Introduction: Given growing elderly population and high prevalence of oral and dental diseases in this age group, this study was conducted to investigate oral health status and related quality of life among older adults in Yazd located in central Iran. Methods: The cross sectional study was carried out on 210 elderly people aged ≥ 60 years under the guise of Yazd health care centers who entered the study via cluster random sampling. Oral health was assessed by DMFT index; and self-reported oral and dental health scale was also tested. Further, to measure the oral health-related quality of life, the Geriatric Oral Health Assessment Index was applied. Data were then analyzed by SPSS software through descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient. Results: The mean score of age for the studied population was 67.22 ± 5.62 years. Of whom 60.48 % were women, 79.05 % were married and 42.4% were edentulous. The oral health-related quality of life mean score was 42.46 ± 5.76 (possible rang 12-60 and the DMFT index mean score was 20.33 ± 4.76. The correlation of oral health-related quality of life score with age (r=-0.213, p=0.002 and DMFT index (r= -0.542, p<0.001 was inversely significant. Further, that had a direct significant correlation with self-reported oral health score(r= 0.302, p<0.001. Conclusion: Elderly people's oral health-related quality of life, self-reported oral and dental health status was not desirable. These factors have significant relationships with each other so that increase in DMFT index was associated with decrease in self-reported oral and dental health.

To determine the impact of chronic periodontitis on oral health-related quality of life in Sri Lankan adults. A cross-sectional study was conducted among 1,400 participants, 35-60 years of age, residing in the Colombo district of Sri Lanka. Data were collected using two interviewer-administered questionnaires and an oral examination. The prevalence, extent and severity of oral impacts increased with the increase in severity of chronic periodontitis. The most commonly experienced impacts were within the domain of physical pain. The adjusted Poisson regression model indicated that chronic periodontitis was significantly associated with the prevalence of oral impacts. The prevalence of oral impacts was 48% and 69% higher in those with moderate and severe periodontitis, respectively, compared with those with no/mild periodontitis. Oral health-related quality of life deteriorates with the increase in severity of chronic periodontitis. © 2016 FDI World Dental Federation.

Individuals with disabilities are regarded as a highly vulnerable population group, particularly as far as oral health is concern. However, few studies have assessed the impact of the oral condition on the quality of life of these individuals. Therefore, the aim of this study is to expand knowledge on the oral health status of the Portuguese adults with mild intellectual disability, and to assess how the patient’s oral health is related to their quality of life. A sample of 240 adults with mild intellectual disabilities linked to the Portuguese Federation for Intellectual Disability, were interviewed using a previously validated version of the Oral Health Impact Profile. An oral health examination was also conducted using three oral health indexes: Clinical Oral Health Index (COHI); Clinical Oral Care Needs Index (COCNI) and the Clinical Oral Prevention Index (COPI). Sociodemographic characteristics and dental health factors were also collected, following statistical analysis. More than half of the individuals (54,9%) presented one or more problems of major to severe impact on health (COHI level 2); only 4,6% of the individuals do not need treatment or examination (COCNI level 0) and 85% of the study sample needs measures of educational or preventive action (COPI level 1). In 76,9% of the participants, oral health had impact on the quality of life. The most affected dimensions of life were physical pain with 61,9%, followed by psychological discomfort and psychological disability with 45,1% and 45%, respectively. With relation to oral health factors and sociodemographic variables it was verified that fewer teeth and higher self-perception of need for dental treatment had a negative impact on the quality of life. On the other hand, institutionalization and an increase in at least one category in the self-perception of the oral health status had a positive impact on the quality of life. Given the high burden of oral disease and the considerable impact on quality of
Full Text Available Diet is important for both quality of life (QoL and survival of patients with oral cancer. Their intake of food is impeded by functional restrictions in chewing and swallowing. In the DÖSAK REHAB STUDY 1652 patients from 38 hospitals within the German-language area of Germany; Austria and Switzerland were examined with regard to functional and psychological variables having an impact on diet. Chewing and swallowing are correlated with mobility of the tongue and the mandible as well as opening of the mouth. Thirty five percent of the patients lost weight; 41% maintained their weight and 24% gained weight. The QoL of patients who were able to maintain their weight and of those who gained weight was significantly better than that of patients who lost weight. A normal diet was important for maintaining weight. Mashed food; liquid food and loss of appetite were closely associated with loss of weight; although it was possible for nutritional counseling and dietary support to be implemented particularly favorably in this respect. Due to problems with eating patients’ strength deteriorated; thus restricting activity. Radiotherapy had a negative impact on diet and weight. It influenced sense of taste; dryness of the mouth; swelling and discomfort when ingesting food. Pain and scars in the region of the operation also cause patients to dislike hard; spicy and sour food. Support from a nutritional counselor in implementing a calorie-rich diet remedied this and such support needs to be integrated into patient management. The fact that a poor nutritional status is of such great importance is well-known; but what is often lacking is the systematic implementation of continued professional nutritional counseling over a long period of time; weight control and psycho-social support of the operated patients; particularly those who also have had radiotherapy.

To investigate the effect of artesunate on radio-sensitivity of human cervical cancer cells in vitro. The human cervical cancer cells HeLa and Siha were used as the experimental cells. MTT assay was used to determine the most appropriate drug concentration in the subsequent experiment, and the effect of human cervical cancer cells treated with artesunate and irradiation of 60 Co γ-rays was studied by using conventional chromosomal aberration analysis and cytokinesis block method (CB method). The results show that when the concentration of artesunate in this experiment was 2.0 μmol/L for HeLa cell and 4.0 μmol/L for Siha cell respectively, the chromosome aberration, micronuclei cell and micronuclei rates of HeLa cells treated with artesunate were more serious than that of the only irradiation, but there is almost no change with Siha cells.

Objective: To investigate the radiosensitizing effects of artesunate on human HeLa cells of cervical cancer in vitro. Methods: Hela cells irradiated with 60 Co γ-rays. The dose rate was 0.635 Gy/min and the radiation dose was 0, 1, 2, 4, 6 Gy, respectively. The anti-proliferation activities of artesunate on HeLa cells were evaluated with MTT assay, to determine the most appropriate drug concentration. The effect of radiosensitivity was observed by using clonogenic assay. The single-hit multi-target model was used to plot the HeLa cell's dose-survival curve, to calculate mean lethal dose, quasi-threshold dose and sensitization enhancement rate, and to evaluate its radiosensitization effect. The apoptosis was analyzed with flow cytometry (FCM) to further test the radiation sensitization of artesunate on HeLa cells. Results: The inhibition of artesunate on HeLa cells increased with concentration. In radiation group, the cell cloning efficiency were 91.67%, 82.02%, 58.06%, 25.01%, respectively, and in artesunate (2.0 μmol/L) + radiation group, the cell cloning efficiency were 74.93%, 60.53%, 22.38%, 5.05%. In radiation group and artesunate (2.0 μmol/L) + radiation group, the mean lethal dose (D 0 ) was 2.95 and 2.07 Gy, respectively, while the qusai-threshold dose (D q ) were 2.01 and 1.24 Gy, respectively, and SER was 1.43. Compared with 2 and 6 Gy radiation group, the apoptosis rate of drug + radiation group increased from 12.26%, 40.08% to 22.71%, 59.92. Conclusions: The inhibiting effect of artesunate on HeLa cells is concentration-dependent. Artesunate has radiosensitizing effect on HeLa cells in vitro. (authors)

Good oral health in older residents of nursing homes is important for general health and quality of life. Very few studies have assessed how oral symptoms affect residents' quality of life. To assess the clinical and subjective oral health, including oral health related quality of life (OHRQoL), and the association of oral symptoms with OHRQoL in older people residing in nursing homes in Islington, London. Overall, 325 residents from nine nursing homes were clinically examined and 180 residents were interviewed to assess their oral symptoms and their OHRQoL using the OIDP measure. Managers and carers working in the homes were also interviewed. Almost two thirds of the sample were dentate (64.5%). 61.3% of dentate and 50.9% of edentate residents reported problems such as dry mouth, sore cracked lips, broken teeth and toothache and ill-fitting dentures. Oral health impacted considerably upon resident's OHRQoL; 20.2% of dentate and 30.9% of edentate reported at least one oral impact in the past 6 months. Sensitive teeth, toothache, bleeding gums, dry mouth and loose natural teeth among the dentate and loose or ill-fitting dentures among the edentate were strongly associated with higher prevalence of oral impacts even after adjusting for demographic and socio-economic factors, and for the number of teeth (dentate only). The burden of oral conditions was considerable. Oral symptoms were very common and were strongly associated with residents' worse OHRQoL. Health promotion programmes are important to help residents maintain an acceptable level of oral health and function.

To assess health-related quality of life (HRQoL) and oral health-related quality of life, and correlate them with unstimulated whole salivary flow (UWSF) and oral sicca symptoms in patients with primary Sjögren's syndrome (PSS). We included 60 patients with PSS and 60 healthy controls matched according to gender and age (±3 years). We measured the UWSF and scored the European League Against Rheumatism (EULAR) Sjögren's Syndrome Patient Reported Index (ESSPRI). We assessed the short version of the SF-36 as a generic measurement of HRQoL and the Xerostomia Quality of Life Scale (XeQoLS) questionnaire to evaluate oral quality of life. We evaluated oral symptoms using an 8-item Visual Analogue Scale (VAS) questionnaire. We observed a poorer HRQoL (lower scores in SF-36) and oral quality of life (higher scores in XeQoLS), as well as a greater severity of symptoms in the VAS questionnaire upon comparing patients vs. controls. The XeQoL correlated with the UWSF (τ = -0.24, P = .008), the ESSPRI (τ =0.45, P = .0001), VAS 1-2 and VAS 5-8 and the SF-36 score (τ = -0.28, P = .002). Patients with PSS had a poorer HRQoL and oral quality of life than controls. UWSF contributes to the oral quality of life which, in turn, has an impact on HRQoL. Symptomatic treatment of xerostomia as well as the prevention of infections, decay and tooth loss would help to improve the oral quality of life in these patients.

To assess changes in the oral health-related quality of life (OHRQoL), after comprehensive oral rehabilitation under general anaesthesia (CORGA), among children (i) <6 years using the Early Childhood Oral Health Impact Scale (ECOHIS) and (ii) aged 6-14 years using the child oral health-related quality of life (COHRQoL) instrument. A total of 136 healthy children who had CORGA were recruited over a period of 12 months. The parent or caregiver of the study participants completed the age-appropriate questionnaire prior to the dental treatment and at the subsequent follow-up appointments (2 weeks and 3 months). Data were analysed using repeated-measures anova and Bonferroni tests. The overall ECOHIS scores decreased significantly (P < 0.001) demonstrating large effect sizes. The greatest decreases were for the domains of child oral symptoms (57.5%) and psychology (38.7%) in the child impact section (CIS) and for the domain of parental distress (38.9%) and family function (40%) in the family impact section (FIS). For COHRQoL, the overall P-CPQ and FIS scores decreased significantly for all items (P < 0.001), demonstrating large effect sizes. The greatest decreases were for the domains of oral symptoms (77.7%), functional limitations (74.3%), and the FIS (80.1%). The OHRQoL of children in both age groups (<6 and 6-14 years) was significantly improved after CORGA. © 2015 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
Oral health-related quality of life after prosthetic rehabilitation in patients with oral cancer: A longitudinal study with the Liverpool Oral Rehabilitation Questionnaire version 3 and Oral Health Impact Profile-14 questionnaire.
Dholam, K P; Chouksey, G C; Dugad, J
Prosthodontic rehabilitation helps to improve the oral health-related quality of life (OHRQOL). The Liverpool Oral Rehabilitation Questionnaire (LORQ) and Oral Health Impact Profile (OHIP) are specific tools that measure OHRQOL. The primary objective of this study was to assess the impact of oral rehabilitation on patients' OHRQOL following treatment for cancer of oral cavity using LORQ version 3 (LORQv3) and OHIP-14 questionnaire. Secondary objectives were to identify issues specific to oral rehabilitation, patients compliance to prosthetic rehabilitation, the effect of radiation treatment on prosthetic rehabilitation, to achieve meaningful differences over a time before & after prosthetic intervention, to carryout and document specific patient-deprived problem. Seventy-five oral cancer patients were studied. Patients were asked to rate their experience of dental problems before fabrication of prosthesis and after 1 year using LORQv3 and OHIP-14. The responses were compared on Likert scale. Patients reported with extreme problems before rehabilitation. After 1 year of prosthetic rehabilitation, there was improvement noticed in all the domain of LORQv3 and OHIP-14. Complete compliance to the use of prosthetic appliances for 1 year study period was noted. In response to the question no. 40 (LORQv3), only 15 patients who belonged to the obturator group, brought to notice the problems which were not addressed in the LORQv3 questionnaire. The study showed that the oral cancer patients coped well and adapted to near normal oral status after prosthetic rehabilitation. This contributed to the improved overall health-related quality of life.

The aim of this study was to assess the effect of oral health on aspects of daily life measured by the Dental Impact Profile (DIP) in 35- to 47-year-old individuals in Norway, and to study associations between reported effects and demographic variables, subjectively assessed oral health, general health, oral health behaviour and clinical oral health. A stratified randomized sample of 249 individuals received a questionnaire regarding demographic questions, dental visits, oral hygiene behaviour, self-rated oral health and general health and satisfaction with oral health. The DIP measured the effects of oral health on daily life. Teeth present and caries experience were registered by clinical examination. Bi- and multivariate analyses and factor analysis were used. Items most frequently reported to be positively or negatively influenced by oral health were chewing and biting, eating, smiling and laughing, feeling comfortable and appearance. Only 1% reported no effects of oral health. Individuals with fewer than two decayed teeth, individuals who rated their oral health as good or practised good oral health habits reported more positive effects than others on oral quality of life (P ≤ 0.05). When the variables were included in multivariate analysis, none was statistically significant. The subscales of the DIP were somewhat different from the originally suggested subscales. This study showed that most adults reported oral health to be important for masticatory functions and confirmed that oral health also had impacts on other aspects of life. © 2011 John Wiley & Sons A/S.

To assess oral health status and to describe the possible factors that could affect the oral health-related quality of life (OHRQoL) among a group of pregnant rural women in South India. A total of 259 pregnant women (mean age 26 +/- 5.5 years) who participated in the cross-sectional study were administered the Oral Health Impact Profile (OHIP-14) questionnaire and were clinically examined for caries and periodontal status. The highest oral impact on quality of life was reported for 'painful mouth' (mean: 1.7) and 'difficulty in eating' (mean: 1.1). On comparing the mean OHIP-14 scores against the various self-reported oral problems, it was seen that the mean OHIP-14 scores were significantly higher among those who reported various oral problems than those who did not. Those with previous history of pregnancies had more severe levels of gingivitis than those who were pregnant for the first time. Also gingival index scores, community periodontal index of treatment needs scores and previous pregnancies was associated with poorer OHRQoL scores. Increased health promotion interventions and simple educational preventive programmes on oral self-care and disease prevention during pregnancy can go a long way in improving oral health and lessening its impact on the quality of life in this important population.
Full Text Available The living conditions of young adults in Sweden have changed during the last decades due to the economic and employment situation in society. Although oral health is mainly considered to be good in this age group, their use of dental care has decreased and their priorities and opportunities regarding oral health are little known. The purpose of this study was to describe the views of Swedish young adults on their oral health and oral health-related quality of life (OHRQoL. The design of the study was qualitative, using content analysis. Sixteen young adults, aged 21–29 years, were interviewed. The findings from the interviews were summarized under the theme “Young adults reflected on their OHRQoL in a time perspective” consisting of three categories: “Past experiences, Present situation, and Future prospects.” The OHRQoL of young adults is dependent not only on their own experiences of oral health during childhood and their received dental care but also on their present self-perceived oral health, oral health habits, and social life; together with their expectations of future oral health. The findings in this study indicate that the oral health awareness and needs of young adults, as well as their expectations of oral care, merit further follow-up.

This report intends to review the global burden of oral disease among older people and to examine their oral health needs. The evidence on the inter-relationships between poor oral health conditions of older people, general health and quality of life is highlighted. Finally, WHO strategies to improve oral health of older people are reviewed. The information relevant to this review was extracted from the WHO Global Oral Health Data Bank, the PubMed database, and the Cochrane Library. Surveys were carried out according to the criteria recommended by the WHO epidemiological manual Oral Health Surveys - Basic Methods. In addition, global data were sought on coverage of oral health care among older people. Finally, WHO policy documents on health care for aged people were gathered through the WHO website. Across the globe, many older people suffer from oral pain or discomfort. Poor oral health during old age is mostly manifest in high caries experience, high prevalence rates of advanced periodontal disease, severe tooth loss, dry mouth, and oral pre-cancer/cancer. In both developing and developed countries, the burden of disease is particularly high among underprivileged and disadvantaged older people. In numerous countries, high proportions of the aged population are not covered by primary oral health care; this is mainly the case in low and middle income countries due to a critical shortage of dentists. In 2015, the WHO published the World Report on Ageing and Health, which outlines a framework for action to foster healthy ageing. The policies are highly relevant to the improvement of oral health. Transformation of oral health systems away from a disease-based curative model and towards disease prevention, as well as the provision of older-person-centred integrated care are required. Moreover, wide-ranging public health action on ageing is urgently needed.

Objective: To investigate the radiosensitization of artesunate on nude mouse transplanted with HeLa cells,and to explore its possible mechanisms. Methods: HeLa cells were inoculated into the nude mice to establish tumor model. Mice were randomly divided into 4 groups as blank control,artesunate group, radiation group and artesunate + radiation group when average volume of tumor were about 5 mm × 5 mm× 5 mm. During the term of treatment, the volume of tumors were measured every 2 days. After 14 days treatment, the mice were killed and tumor tissues were harvested for flow cytometry to detect the alteration of cell cycle. Meanwhile, the pathological change of the tumor tissue was observed with HE staining method, and the change of expression of cycle regulatory protein Cyclin B1, Cdc2 and Wee1 were detected by Western blot. Results: The growth of tumor was significantly inhibited by artesunate combined with radiation and its inhibition rate was 72.34%. Flow cytometry results showed that the percent of cells in G 1 phase increased and G 2 phase decreased in the artesunate + radiation group compared with those in irradiation group (t=4.41, 4.12, P<0.05). The expression level of Cyclin B1 was obviously increased while that of Wee1 decreased in the artesunate + radiation compared with irradiation group. There was no difference in the expression of Cdc2 among the four groups. Conclusions: Artesunate can dramatically increase the radiosensitivity of transplanted tumor of HeLa cells. The possible mechanism might be related to the decreasing G 2 phase by regulating the expression of Cyclin B1 and Wee1. (authors)

However, the use of clozapine has been limited by its adverse effects on metabolism. Artesunate is a semisynthetic derivative of artemisinin and was shown to decrease the plasma cholesterol and triglyceride in rabbits and rats in recent studies. The aim of this study was to examine possible effects of artesunate on the clozapine-induced metabolic alterations in rats given saline, clozapine, artesunate, or clozapine plus artesunate for 6 weeks. The clozapine group showed significantly high plasma levels of triglyceride, hepatic steatosis, and fibrosis along with high levels of C-reactive protein, alanine aminotransferase, and aspartate aminotransferase compared to the saline group. But the treatment had no effect on weight gain and caused no hyperglycemia, hyperinsulinemia, and behavioral changes in the rats. More significantly, these clozapine-induced changes were not seen in rats coadministered with clozapine plus artesunate. These results added evidence supporting psychiatrists to try add-on treatment of artesunate in schizophrenia patients to ameliorate clozapine-induced adverse metabolic effects. Keywords: artesunate, clozapine, dyslipidemia, hepatic steatosis, schizophrenia

To assess the oral health quality of life among Malaysian dental students using the Oral Impacts on Daily Performance (OIDP) scale. Malaysian dental students of Melaka Manipal Medical College, Manipal campus, Manipal University, Manipal answered a structured questionnaire recording the demographic characteristics, behavioral characteristics and eight items of OIDP. The mean OIDP ADD and OIDP SC scores were respectively, 4.10 (sd = 5.16, range 8 - 40) and 2. 3 (sd = 2.3, range 0-8). A total of 50%, 32.9% and 28.6% of the dental students confirmed difficulties with eating, cleaning teeth and sleeping and relaxing, respectively. Statistically significant relationships were observed between OIDP (ultimate oral impact) and a count of non-clinical oral health indicators representing the second (intermediate) levels of oral impact. Logistic regression analysis revealed that dental students who were dissatisfied with their oral health had greater oral impact than their counterparts. The odds ratios for satisfaction with oral health, dental visits and frequency of brushing teeth were respectively 1.74 (0.58-5.32), 0.59 (0.11-3.24) and 1.33 (0.41-4.30). The study reports the Oral Impact on Daily Performance among Malaysian dental students and provides evidence of importance of social and behavioral characteristics in shaping dental students response.

Dry mouth is a frequently occurrence in elderly people and causes numerous clinical and social problems. To investigate the quality of life in geriatric patients living in nursing homes depending on the subjective sensation of dry mouth and associated oral parameters. A total of 62 male and female elderly patients living in 7 cooperating nursing homes were interviewed employing questionnaires with regard to their oral health-related quality of life (GOHAI) and their subjective perception of dry mouth (sXI-D). Dental status, drinking habits and current medication were documented. The mean GOHAI score was 53.6 and the mean sXI-D score was 7.9. Oral health-related quality of life was significantly influenced by the subjective sensation of dry mouth (p Xerostomia was significantly influenced by the number of medications consumed (p = 0.039). Xerostomia has a significant impact on the oral health-related quality of life of elderly people living in nursing homes. Thus, dental treatment should focus on the alleviation of xerostomia to improve the oral health-related quality of life in the elderly population.

Full Text Available The therapeutic potential of oil from blends of selected culinary spices against artesunate-induced testicular injury in albino rats was investigated. Two groups of rats each were pretreated with the oil at 1.5 and 3.00 mL respectively for seven days and after which administered artesunate (100 mg/kg bw for seven days; two other groups were administered artesunate for seven days and after which post treated with the oil at both doses respectively for another seven days; another groups were co-administered artesunate and the oil for seven days. A group was administered artesunate only for seven days, while another was fed chows only. After sacrifice, the testicular homogenates of the rats were analysed for GSH, Superoxide Dismutase (SOD, Catalase (CAT, Lipid peroxidation (LPO, 3β-HSD and 17β-HSD activities. LPO and GSH levels, SOD and CAT activities were significantly (p < 0.05 higher in rats administered artesunate only, these were significantly lowered in all treatment groups. Administration of artesunate significantly suppressed steroidogenesis, this was attenuated in all treatment groups. The antioxidant, anti-lipid peroxidative and steriodogenetic effects of the oil indicate its protective potential against artesunate-induced oxidative testicular damage.

The purpose of this study was to investigate the dental and some other aspects of oral health status of young patients with congenital bleeding disorders (CBD) and the impact of these on their quality of life (OHR-QoL) compared with controls. DMFS-dmfs (Decayed, Missed, Filled Tooth surfaces in permanent and primary teeth) scores, Simplified oral hygiene index, occurance of hypoplasia of first permanent molars, Temporomandibular joint dysfunction and occlusion of 46 CBD patients at the age range of 2-15 years and 46 of other children as control were compared, and the impact of their oral health situation on quality of life was also investigated. Data were analysed by chi-square, t-test and Pearson correlation. Patients were significantly more caries-free with less decayed teeth in primary-permanent dentition (P = 0.03, t = -2.17).The mean scores of OHR-QoL of CBD patients and controls were not significantly different. Oral Bleeding was the significant variable in relation to 'oral health-related quality of life' in CBD groups (Pearson correlation, r = -0.56, P = 0.000). OHR-QoL in the control group was related to dmfs score (r = -0.392, P = 0.011) and male gender (r = -0.329, P = 0.026). Congenital bleeding disorder CBD patients were found to have a better dental health situation in primary dentition compared with controls; however, their 'oral health-related quality of life' was similar. Oral bleeding was the only significant factor related to OHR-QoL in CBD. It shows an overall importance of development of comprehensive care centres for CBD as the main cause of this achievement. © 2012 Blackwell Publishing Ltd.

Oral diseases are highly prevalent and impact on oral health-related quality of life (OHRQoL). However, time changes in OHRQoL have been scarcely investigated in the current context of general improvement in clinical oral health. This study aims to examine changes in OHRQoL between 1998 and 2009 among adults in England, and to analyse the contribution of demographics, socioeconomic characteristics and clinical oral health measures. Using data from two nationally representative surveys in England, we assessed changes in the Oral Health Impact Profile-14 (OHIP-14), in both the sample overall (n=12 027) and by quasi-cohorts. We calculated the prevalence and extent of oral impacts and summary OHIP-14 scores. An Oaxaca-Blinder type decomposition analysis was used to assess the contribution of demographics (age, gender, marital status), socioeconomic position (education, occupation) and clinical measures (presence of decay, number of missing teeth, having advanced periodontitis). There were significant improvements in OHRQoL, predominantly among those that experienced oral impacts occasionally, but no difference in the proportion with frequent oral impacts. The decomposition model showed that 43% (-4.07/-9.47) of the decrease in prevalence of oral impacts reported occasionally or more often was accounted by the model explanatory variables. Improvements in clinical oral health and the effect of ageing itself accounted for most of the explained change in OHRQoL, but the effect of these factors varied substantially across the lifecourse and quasi-cohorts. These decomposition findings indicate that broader determinants could be primarily targeted to influence OHRQoL in different age groups or across different adult cohorts. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The aim of this study was to investigate the relationship between patients' oral health-related quality of life, satisfaction with their dentition, and their personality profiles. Eighty-four patients (30 males and 54 females; mean age 31.9+/-12.7 years) seeking routine dental treatment were recruited for this study. A "Dental Impact on Daily Living" (DIDL) questionnaire was used to assess dental satisfaction and impact on daily living. An "Oral Health Impact Profile" (OHIP) was used to measure self-reported discomfort, disability, and dysfunction caused by oral conditions. Oral health-related quality of life was assessed using the "United Kingdom Oral Health Related Quality of Life" measure (OHQoL-U.K). A "NEO Five Factor inventory" (NEO-FFI) was used to assess personality profiles. The dentition has a measurable impact on daily living as well as with satisfaction with appearance, pain levels, oral comfort, general performance, and eating capability (p=0.000). Younger patients had more profound oral health impacts (p=0.045) and higher neuroticism scores (0.043). OHIP scores were significantly related to OHQoL-UK scores (p=0.000). DIDL scores had significant correlations with OHIP and OHQoL-UK scores (p<0.05). Significant correlations were established between neuroticism and satisfaction with oral comfort, extraversion and total satisfaction and satisfaction with general performance, and openness and satisfaction with appearance (p<0.05). OHIP and OHQoL-UK scores had no significant correlations with psychological profiles. The status of the oral cavity can have a definitive impact on patients' daily living and quality of life regardless age, gender, and level of education. Patients' satisfaction with their dentition has definitive impacts on daily living, quality of life, and dental perceptions. Personality profiles (neuroticism; extraversion, and openness) may influence dental perceptions, play a significant role in shaping satisfaction with dentition, and help
AbstractBackgroundSevere malaria is a medical emergency with high mortality. Prompt achievement of therapeutic concentrations of highly effective anti-malarial drugs reduces the risk of death. The aim of this study was to assess the pharmacokinetics and pharmacodynamics of intravenous artesunate in Ugandan adults with severe malaria.MethodsFourteen adults with severe falciparum malaria requiring parenteral therapy were treated with 2.4 mg\\/kg intravenous artesunate. Blood samples were collected after the initial dose and plasma concentrations of artesunate and dihydroartemisinin measured by solid-phase extraction and liquid chromatography-tandem mass spectrometry. The study was approved by the Makerere University Faculty of Medicine Research and Ethics Committee (Ref2010-015) and Uganda National Council of Science and Technology (HS605) and registered with ClinicalTrials.gov (NCT01122134).ResultsAll study participants achieved prompt resolution of symptoms and complete parasite clearance with median (range) parasite clearance time of 17 (8–24) hours. Median (range) maximal artesunate concentration (Cmax) was 3260 (1020–164000) ng\\/mL, terminal elimination half-life (T1\\/2) was 0.25 (0.1-1.8) hours and total artesunate exposure (AUC) was 727 (290–111256) ng·h\\/mL. Median (range) dihydroartemisinin Cmax was 3140 (1670–9530) ng\\/mL, with Tmax of 0.14 (0.6 – 6.07) hours and T1\\/2 of 1.31 (0.8–2.8) hours. Dihydroartemisinin AUC was 3492 (2183–6338) ng·h\\/mL. None of the participants reported adverse events.ConclusionsPlasma concentrations of artesunate and dihydroartemisinin were achieved rapidly with rapid and complete symptom resolution and parasite clearance with no adverse events.

To assess the parents' perception of the oral health-related quality of life (OHRQOL) in children with Cerebral Palsy (CP) and compare it with normally developing children. 63 children with CP were recruited from 8 disability centers, and 99 healthy controls were recruited from 5 elementary schools. The ages of the children in both groups were from 6-12 years. The Franciscan Hospital for Children Oral Health-Related Quality of Life (FHC-OHRQOL) was used to measure the OHRQOL and an oral examination was conducted in the schools/centers of the children to assess the teeth, gingival health, and oral hygiene. The FHC-OHRQOL showed a significant difference in 3 out of 4 sections indicating lower OHRQOL in the CP group. The examination showed no significant difference in the dental and gingival health and in the level of oral hygiene. The OHRQOL of children with CP is significantly lower than that of normally developing children although the oral health status of children with CP is not significantly different from that of normally developing children.

To explore ethnic disparities in oral health related quality of life (OHQoL) among adults, and the role that socioeconomic factors play in that association. Data from 705 adults from a socially deprived, ethnically diverse metropolitan area of London (England) were analysed for this study. Ethnicity was self-assigned based on the 2001 UK Census categories. OHQoL was measured using the Oral Health Impact Profile (OHIP-14), which provides information on the prevalence, extent and intensity of oral impacts on quality of life in the previous 12 months. Ethnic disparities were assessed in logistic regression models for prevalence of oral impacts and negative binomial regression models for extent and intensity of oral impacts. The prevalence of oral impacts was 12.7% (95% CI: 10.2-15.1) and the mean OHIP-14 extent and severity scores were 0.27 (95% CI: 0.20-0.34) and 4.19 (95% CI: 3.74-4.64), respectively. Black adults showed greater and Asian adults lower prevalence, extent and severity of oral impacts than White adults. However, significant differences were only found for the extent of oral impacts; Black adults reporting more and Asian adults fewer OHIP-14 items affected than their White counterparts. After adjustments for socioeconomic factors, Asian adults had significantly fewer OHIP-14 items affected than White adults (rate ratio: 0.28; 95%CI: 0.08-0.94). This study found disparities in OHQoL between the three main ethnic groups in South East London. Asian adults had better and Black adults had similar OHQoL than White adults after accounting for demographic and social factors. Copyright© 2017 Dennis Barber Ltd.

This study was conducted to investigate the degree of dry mouth and oral health-related quality of life and to identify factors contributing to oral health-related quality of life for community-dwelling elders. A descriptive correlational study design was used. Participants were 156 older adults from two senior welfare centers. Data were collected on February 21, 22 and 29, 30, 2009 using structured questionnaires. Enter type multiple regression analysis was used to identify factors influencing oral health-related quality of life according to general and oral health characteristics. There were significant differences in oral health-related quality of life according to living arrangement, insurance, smoking, number of natural teeth, and denture type. The oral health-related quality of life had significant correlations with the number of chronic disease, number of medications, and dry mouth. Factors influencing oral health-related quality of life for community-dwelling older adults were dry mouth, number of chronic disease, and medical aid, which explained about 47.9% of total variance. These results indicate that in order to promote oral health-related quality of life for older adults, prevention or management of chronic diseases as well as oral health and dry mouth are needed for this population, and especially economically poor elders.

In this study scales and items for the Oral Cancer Quality-of-life Questionnaire (QOL-OC) were designed and the instrument was evaluated. The QOL-OC was developed and modified using the international definition of quality of life (QOL) promulgated by the European Organization for Research and Treatment of Cancer (EORTC) and analysis of the precedent measuring instruments. The contents of each item were determined in the context of the specific characteristics of oral cancer. Two hundred thirteen oral cancer patients were asked to complete both the EORTC core quality of life questionnaire (EORTC QLC-C30) and the QOL-OC. Data collected was used to conduct factor analysis, test-retest reliability, internal consistency, and construct validity. Questionnaire compliance was relatively high. Fourteen of the 213 subjects accepted the same tests after 24 to 48 h demonstrating a high test-retest reliability for all five scales. Overall internal consistency surpasses 0.8. The outcome of the factor analysis coincides substantially with our theoretical conception. Each item shows a higher correlation coefficient within its own scale than the others which indicates high construct validity. QOL-OC demonstrates fairly good statistical reliability, validity, and feasibility. However, further tests and modification are needed to ensure its applicability to the quality-of-life assessment of Chinese oral cancer patients.

Artemisinin and its derivatives were considered to exert a broad spectrum of anti-cancer activities, and they induced significant anti-cancer effects in tumor cells. Artemisinin and its derivatives could be absorbed quickly, and they were widely distributed, selectively killing tumor cells. Since low concentrations of artesunate primarily depended on oncosis to induce cell death in tumor cells, its anti-tumor effects were undesirable and limited. To obtain better anti-tumor effects, in this study, we took advantage of a new nanotechnology to design novel artesunate-loaded bovine serum albumin nanoparticles to achieve the mitochondrial accumulation of artesunate and induce mitochondrial-mediated apoptosis. The results showed that when compared with free artesunate's reliance on oncotic death, artesunate-loaded bovine serum albumin nanoparticles showed higher cytotoxicity and their significant apoptotic effects were induced through the distribution of artesunate in the mitochondria. This finding indicated that artesunate-loaded bovine serum albumin nanoparticles damaged the mitochondrial integrity and activated mitochondrial-mediated cell apoptosis by upregulating apoptosis-related proteins and facilitating the rapid release of cytochrome C.

Full Text Available Abstract Background The World Health Organization endorses the use of artemisinin-based combination therapy for treatment of acute uncomplicated falciparum malaria in the second and third trimesters of pregnancy. However, the effects of pregnancy on the pharmacokinetics of artemisinin derivatives, such as artesunate (AS, are poorly understood. In this analysis, the population pharmacokinetics of oral AS, and its active metabolite dihydroartemisinin (DHA, were studied in pregnant and non-pregnant women at the Kingasani Maternity Clinic in the DRC. Methods Data were obtained from 26 pregnant women in the second (22 - 26 weeks or the third (32 - 36 weeks trimester of pregnancy and from 25 non-pregnant female controls. All subjects received 200 mg AS. Plasma AS and DHA were measured using a validated LC-MS method. Estimates for pharmacokinetic and variability parameters were obtained through nonlinear mixed effects modelling. Results A simultaneous parent-metabolite model was developed consisting of mixed zero-order, lagged first-order absorption of AS, a one-compartment model for AS, and a one-compartment model for DHA. Complete conversion of AS to DHA was assumed. The model displayed satisfactory goodness-of-fit, stability, and predictive ability. Apparent clearance (CL/F and volume of distribution (V/F estimates, with 95% bootstrap confidence intervals, were as follows: 195 L (139-285 L for AS V/F, 895 L/h (788-1045 L/h for AS CL/F, 91.4 L (78.5-109 L for DHA V/F, and 64.0 L/h (55.1-75.2 L/h for DHA CL/F. The effect of pregnancy on DHA CL/F was determined to be significant, with a pregnancy-associated increase in DHA CL/F of 42.3% (19.7 - 72.3%. Conclusions In this analysis, pharmacokinetic modelling suggests that pregnant women have accelerated DHA clearance compared to non-pregnant women receiving orally administered AS. These findings, in conjunction with a previous non-compartmental analysis of the modelled data, provide further evidence that

This study was planned to evaluate the impact of oral health on the quality of life (QoL) of patients undergoing hematopoietic stem cell transplantation (HSCT). We assessed 200 patients divided into two paired groups: 100 patients prior to HSCT (SG) and 100 healthy volunteers (CG). We applied the Oral Health Impact Profile instrument, which is based on the biopsychosocial problem gradation of World Health Organization (WHO) and relates oral health problems with QoL according to seven dimensions. Fourteen patients in SG were referred for extraction of one to eight teeth, mostly due to deep caries with risk of pulpal infection and possible spread of infection via blood (r = 0.59, p = 0.000). The presence of severely compromised teeth by extensive decay correlated with Oral Health Impact Profile (OHIP-14). The Mann-Whitney test showed a significant difference between SG and CG in the following dimensions: functional limitation (p disability (p = 0.016), and social disability (p = 0.01). The impact of oral health on QoL of onco-hematologic patients is weak but is greater as compared to healthy ones. Nevertheless, a significant impact is seen in patients with severely compromised teeth. The negligence of oral care, proper hygiene, and the search for dental care may increase the risk for local and systemic infections.

A detailed pharmacokinetic analysis was performed with 47 children from Papua New Guinea with uncomplicated falciparum or vivax malaria treated with artesunate (ARTS) suppositories (Rectocaps) given in two doses of approximately 13 mg/kg of body weight 12 h apart. Following an intensive sampling protocol, samples were assayed for ARTS and its primary active metabolite, dihydroartemisinin (DHA), by liquid chromatography-mass spectrometry. A population pharmacokinetic model was developed to describe the data. Following administration of the first dose, the mean maximal concentrations of ARTS and DHA were 1,085 nmol/liter at 0.9 h and 2,525 nmol/liter at 2.3 h, respectively. The absorption half-life for ARTS was 2.3 h, and the conversion half-life (ARTS to DHA) was 0.27 h, while the elimination half-life of DHA was 0.71 h. The mean common volumes of distribution for ARTS and DHA relative to bioavailability were 42.8 and 2.04 liters/kg, respectively, and the mean clearance values relative to bioavailability were 6 and 2.2 liters/h/kg for ARTS and DHA, respectively. Substantial interpatient variability was observed, and the bioavailability of the second dose relative to that of the first was estimated to be 0.72. The covariates age, sex, and alpha-thalassemia genotype were not influential in the pharmacokinetic model development; but the inclusion of weight as a covariate significantly improved the performance of the model. An ARTS suppositories dose of 10 of 20 mg/kg is appropriate for use in children with uncomplicated malaria.

Artemisinin-based combination therapy (ACT) is currently promoted as a strategy for treating both uncomplicated and severe falciparum malaria, targeting asexual blood-stage Plasmodium falciparum parasites. However, the effect of ACT on sexual-stage parasites remains controversial. To determine the clearance of sexual-stage P. falciparum parasites from 342 uncomplicated, and 217 severe, adult malaria cases, we reviewed and followed peripheral blood sexual-stage parasites for 4 wk after starting ACT. All patients presented with both asexual and sexual stage parasites on admission, and were treated with artesunate-mefloquine as the standard regimen. The results showed that all patients were asymptomatic and negative for asexual forms before discharge from hospital. The percentages of uncomplicated malaria patients positive for gametocytes on days 3, 7, 14, 21, and 28 were 41.5, 13.1, 3.8, 2.0, and 2.0%, while the percentages of gametocyte positive severe malaria patients on days 3, 7, 14, 21, and 28 were 33.6, 8.2, 2.7, 0.9, and 0.9%, respectively. Although all patients were negative for asexual parasites by day 7 after completion of the artesunate-mefloquine course, gametocytemia persisted in some patients. Thus, a gametocytocidal drug, e.g., primaquine, may be useful in combination with an artesunate-mefloquine regimen to clear gametocytes, so blocking transmission more effectively than artesunate alone, in malaria transmission areas.

Objectives: To evaluate quality of life (QOL) in patients with squamous cell carcinoma of oral and oropharyngeal region. Methodology: This is prospective longitudinal study was conducted at ENT department Dow University Hospital and Radiotherapy Department KIRAN from November 2012 to November 2015. It included 56 patients of squamous cell carcinoma (SCC) of oral cavity and oropharynx regions who had completed cancer treatment (Wide local excision +/-Neck dissection +/- Radiotherapy). UW QOL questionnaire is taken as the tool to analyze the quality improvement in the domains of pain, appearance, activity, recreation, swallowing, chewing, speech, shoulder, taste, saliva, mood and anxiety. Comparative analysis used to assess all 12 factors associated with cancer patients. A paired t-test was used to compare preoperative and 6 months or more post-operative QOL rating. Results: Six months or more after surgery, 13 patients were lost to follow up and 9 died. 34 patients completed the UW QOL. Cancer Survivors presented overall significantly poorer QOL. QOL improved in the domains of activity, shoulder pain, mood and anxiety. Conclusion: This study recommend Quality of life assessment of oral and oropharyngeal cancers which may contribute to functional, psychological and somatic limitations and likely alter the treatment methodology where cure of cancer is equally good for any modality. This study also identifies that cases of early cancer of oral and oropharyngeal region would not compromise QOL of the patients significantly. (author)
Full Text Available The research goals include: 1 assessment the quality of life of those patients who have defects of tooth rows not replaced by orthopedic appliances on the basis of the complex analysis; 2 choice of more reasonable method of treatment. The use of dental questionnaires such as Oral Health Impact Profile-14 (OHIP-14 while treating oral pathology allows both optimizing an approach to choosing an appropriate treatment method and making more successful prognosis as to the efficiency of treatment being performed. The quality of life of those patients who have tooth rows defects not replaced by orthopedic appliances depends on sex, age, family status, employment and extent of tooth rows defects. Patients with tooth rows defects not replaced by orthopedic appliances accompanied by diseases of peri-odontium are characterized by worse quality of life. This fact must be taken into consideration while planning patients' treatment

This study was to evaluate the effectiveness of oral hygiene care in improving oral health- and health-related quality of life (OHRQoL and HRQoL) among patients receiving outpatient stroke rehabilitation. Subjects were randomized to: (1) a conventional oral hygiene care programme (COHCP) comprising a manual toothbrush, and oral hygiene instruction, or (2) an advanced oral hygiene care programme (AOHCP) comprising a powered toothbrush, 0.2% chlorhexidine mouthrinse, and oral hygiene instruction. The interventional period lasted for 3 months, followed by a 3-month observational period. HRQoL was assessed by SF-12, and OHRQoL was assessed by Oral Health Impact Profile-14 (OHIP-14), General Oral Health Assessment Index (GOHAI), and Oral Health Transitional Scale (OHTS). Participants in AOHCP group had significantly better OHRQoL at the end of clinical trial as assessed by OHTS (p < 0.01), and at the end of observational study as assessed by GOHAI (p < 0.05) than those in the COHCP. Participants in the AOHCP group had significantly better HRQoL as assessed by physical component summary score (PCS) the end of both 3 and 6 months (both p < 0.05). This study provided the evidence that the AOHCP was more effective than the COHCP within stroke rehabilitation in improving subjective health.

Oral histopathology is a course which needs to be combined with theory and practice closely. Experimental course plays an important role in teaching oral histopathology. Here, we aim to explore a series of effective measures to improve the teaching quality of experimental course and tried to train observation, thinking, analysis and problem solving skills of dental students. We re-edited and updated the experimental textbook "guidelines of experimental course of oral histopathology", and published the reference book for experimental course--"color pocket atlas of oral histopathology: experiment and diadactic teaching". The number of clinicopathological cases for presentation and class discussion was increased, and high-quality teaching slides were added and replaced the poor-quality or worn out slides. We established a variety of teaching methods based on the internet, which provided an environment of self-directed learning for dental students. Instead of simple slice-reading examination, a new evaluation system based on computer was established. The questionnaire survey showed that the students spoke positively on the teaching reform for experimental course. They thought that the reform played a significant role in enriching the teaching content, motivating learning interest and promoting self-study. Compared with traditional examination, computer-based examination showed a great advantage on mastering professional knowledge systematically and comprehensively. The measures adopted in our teaching reform not only effectively improve the teaching quality of experimental course of oral histopathology, but also help the students to have a clear, logical thinking when facing complicated diseases and have the ability to apply theoretical knowledge into clinical practice.

Full Text Available INTRODUCTION: Toxoplasmosis is usually a benign infection, except in the event of ocular, central nervous system (CNS, or congenital disease and particularly when the patient is immunocompromised. Treatment consists of drugs that frequently cause adverse effects; thus, newer, more effective drugs are needed. In this study, the possible activity of artesunate, a drug successfully being used for the treatment of malaria, on Toxoplasma gondii growth in cell culture is evaluated and compared with the action of drugs that are already being used against this parasite. METHODS: LLC-MK2 cells were cultivated in RPMI medium, kept in disposable plastic bottles, and incubated at 36ºC with 5% CO2. Tachyzoites of the RH strain were used. The following drugs were tested: artesunate, cotrimoxazole, pentamidine, pyrimethamine, quinine, and trimethoprim. The effects of these drugs on tachyzoites and LLC-MK2 cells were analyzed using nonlinear regression analysis with Prism 3.0 software. RESULTS: Artesunate showed a mean tachyzoite inhibitory concentration (IC50 of 0.075µM and an LLC MK2 toxicity of 2.003µM. Pyrimethamine was effective at an IC50 of 0.482µM and a toxicity of 11.178µM. Trimethoprim alone was effective against the in vitro parasite. Cotrimoxazole also was effective against the parasite but at higher concentrations than those observed for artesunate and pyrimethamine. Pentamidine and quinine had no inhibitory effect over tachyzoites. CONCLUSIONS: Artesunate is proven in vitro to be a useful alternative for the treatment of toxoplasmosis, implying a subsequent in vivo effect and suggesting the mechanism of this drug against the parasite.

Esthetics is an important part of quality of life and a frequent reason for orthodontic treatment demand. It was the aim of this study to investigate whether esthetic impairments, related to overjet and overbite, can be assessed with an established oral health-related quality of life instrument. Data from 1968 participants (age: 16-90 years; 69.8% female) from three German surveys were analyzed. Esthetic impairments of oral health-related quality of life were measured with four questions of the Oral Health Impact profile (OHIP), which comprise esthetic aspects of oral health-related quality of life. Higher values represent greater esthetic impairment (sum score: 0-16). Overbite and overjet values were categorized (≤ - 1 mm, 0-1 mm, 2-3 mm, 4-5 mm, ≥ 6 mm). The specific impact of each category on esthetic impairment, in relation to the reference category (2-3 mm), was calculated in linear regression analyses. The type of relationship and the specific impact of overbite and overjet were evaluated in regression analyses with fractional polynomials. Overbite ranged from - 5 to 15 mm (mean: 3.2 mm) and overjet from - 7 to 19 mm (mean: 3.1 mm). Both an increase and a decrease in overjet, in relation to the reference category, resulted in more esthetic-related oral health-related quality of life impairments. However, in this model, only the effect for increased overjet was statistically significant (4-5 mm: + 0.4 OHIP points; ≥ 6 mm: + 0.9 OHIP points). In the regression analysis with fractional polynomials, both an increase and a decrease in overjet resulted in more esthetic impairments, characterized by a U-shaped relationship. No association could be verified for overbite. A substantial increase or decrease of overjet from the reference values is associated with esthetic impairments of oral health-related quality of life, whereas the extent of overbite seems to have no impact on esthetics.

The efficacy of full mouth rehabilitation (FMR) on oral health-related quality of life of physically disabled children was assessed. This prospective study was performed at Dental Department of Sultan Bin Abdulaziz Humanitarian City, Riyadh, and King Abdulaziz University Hospital, Jeddah, Saudi Arabia, during May 2012 to September 2014. A total of 186 physically disabled children aged 11-14 years were assigned to a test group (n = 97) or a control group (n = 89). FMR was applied for test group children at baseline and 3 months' visits, whereas those in the control group did not receive FMR. Both group children received dental kits and oral hygiene instructions. Children were asked to complete the Child Perceptions Questionnaire, whereas Parental-Caregiver Perceptions Questionnaire and Family Distress Domain questionnaire were completed by the parents/caregivers at baseline and 6 months' visits. Children in both groups showed positive trends in oral symptoms at 6 months compared with those at baseline. However, when they were compared to control, significant improvement in oral symptoms was observed in the test group at 6 months' visit (p < .05). Also when they were compared to control, significant improvements were observed in the functional limitation, emotional, and social well-being subscales of the Child Perceptions Questionnaire and on the Parental-Caregiver Perceptions Questionnaire scales at the end of the study (p < .05). Compared to the parents/caregivers of the control children, the parents/caregivers of the test-group children reported insignificant but positive trends in Family Distress Domain at the end of the study (p < .05). FMR in children reduced oral-related problems subsequently to a better oral health-related quality of life.
Full Text Available Background: The aim of this study was to assess the oral health-related quality of life in adult patients who visit the Dental Clinic of the Faculty of Stomatology, Pancevo, using a Serbian version of 14-items Oral Health Impact Profile (OHIP14 Questionnaire. Material and Methods: A total of 89 respondents (42 women and 47 men, mean age 52.83 ± 13.74 years filled in the questionnaire themselves. Three calibrated dentists recorded the oral health status of the respondents (number of healthy, decayed, filled and missing teeth, the type and time of wearing prosthodontic replacements, if they existed, and assessed the need for prosthodontic treatment. The total OHIP-14 score was calculated by adding scores for all fourteen items; OHIP-14 subscale scores were calculated by adding the scores for the two items in each of the seven subscales. Results: Mean total OHIP score was 10.25 ± 8.89. Patients with less than eight extracted teeth, wearers of fixed prosthodontic appliances and patients without replacements who did not need prosthodontic treatment reported better oral health-related quality of life. The most severe oral impacts assessed by the subscale OHIP14 scores were recorded in psychological discomfort (2.44 ± 2.18, physical pain (1.87 ± 1.73 and psychological disability subscale (1.83 ± 1.88. Women more often than men were dissatisfied with their diet and had been irritable in contact with other people. Conclusion: Further studies using the OHIP14 questionnaire in a larger sample will permit identification of key factors related to poor oral health and planning of treatment protocols and preventive programs for the adult population in Serbia.

Prisoners have worse oral health and greater unmet dental treatment needs than the general population. However, little is known about the impact of the mouth, or attitudes such as dental indifference and consequent patterns of dental service use in this disadvantaged group. The aim was to determine whether dental indifference was associated with the oral health-related quality of life (OHQoL) of prisoners using Andersen's behavioural model of service utilization as the theoretical framework. The sample was male prisoners aged 20-35 years attending three prisons in the north of England. Participants took part in interviews and oral examinations. The variables were selected to populate Andersen's model including: predisposing characteristics (socioeconomic status), enabling resources (dental indifference and dental attendance patterns before prison), perceived need (perceived treatment need, satisfaction with appearance of teeth, global rating of oral health), evaluated need (number of decayed teeth), health behaviours (use of dental services while in prison) and health outcomes (OHQoL). Structural equation modelling was used to estimate direct and indirect pathways between variables. Of the 700 men approached, 659 completed the interview and clinical examination. Worse OHQoL was associated with less dental indifference (i.e. greater interest in oral health), previous regular use of dental services, perceived need for treatment and use of prison dental services. The number of decayed teeth and predisposing factors such as qualifications and employment did not predict OHQoL. Dental indifference was related to the OHQoL of prisoners in addition to previous regular use of dental services, a perceived need for treatment and use of dental services while in prison. Dental services in prisons might incorporate methods to address dental indifference in their attempts to improve oral health. The findings also have general implications for the assessment of population oral

To assess the oral health related quality of life (OHRQoL) among older people residing in old-age homes in Delhi, India. Oral health related quality of life was measured by using the Hindi version of Geriatric Oral Health Assessment Index (GOHAI) which was tested for its reliability and validity. Sociodemographic data were collected and questions regarding the self-perception of general health, oral health and perceived need for dental treatment were put forward. Clinical assessment was also performed. The mean additive-GOHAI score of the study population was found to be 41.57 ± 6.07. Statistically significant associations were found between GOHAI and perceived measures. GOHAI scores decreased with a decrease in the number of teeth present and a decrease in the number of teeth having coronal and root caries. Those subjects who were in need of multi-unit prostheses or full prostheses had significantly poorer OHRQoL compared to those without any prosthetic need or need of single-unit prostheses. This study revealed the extent of dental problems in old-age home residents and may help to plan appropriate preventive measures.

The characteristics of the work environment and relationships with family roles may impact on health and be of public health significance. The aims were to investigate the cross-sectional association of work-family conflict with oral- and general health-related quality of life, and well-being. A random sample of 45-54-year olds from Adelaide, South Australia, was surveyed by self-complete questionnaire in 2004-2005 (n = 879, response rate = 43.8%). Health-related quality of life was measured with the OHIP-14 and EQ-VAS instruments, and well-being by the Satisfaction With Life Scale. In adjusted analyses controlling for sex, income, education, tooth brushing frequency and social support, the higher Family Interferes with Work (FIW) tertile and the middle tertile of Work Interferes with Family (WIF) were associated with more oral health-related impacts as measured by OHIP-14 in relation to problems with teeth, mouth or dentures (Beta = 1.64, P Work-family conflict was associated with more oral health impacts and lower general health and well-being among employed middle-aged adults. This supports the view of work-family conflict as a psychosocial risk factor for health outcomes spanning function, health perceptions and well-being, and encompassing both oral health and general health.

Malaria is the leading cause of morbidity and mortality in post-conflict Burundi. To counter the increasing challenge of anti-malarial drug resistance and improve highly effective treatment Burundi adopted artesunate-amodiaquine (AS-AQ) as first-line treatment for uncomplicated Plasmodium falciparum malaria and oral quinine as second-line treatment in its national treatment policy in 2003. Uptake of this policy in the public, private and non-governmental (NGO) retail market sectors of Burundi is relatively unknown. This study was conducted to evaluate access to national policy recommended anti-malarials. Adapting a standardized methodology developed by Health Action International/World Health Organization (HAI/WHO), a cross-sectional survey of 70 (24 public, 36 private, and 10 NGO) medicine outlets was conducted in three regions of Burundi, representing different levels of transmission of malaria. The availability on day of the survey, the median prices, and affordability (in terms of number of days' wages to purchase treatment) of AS-AQ, quinine and other anti-malarials were calculated. Anti-malarials were stocked in all outlets surveyed. AS-AQ was available in 87.5%, 33.3%, and 90% of public, private, and NGO retail outlets, respectively. Quinine was the most common anti-malarial found in all outlet types. Non-policy recommended anti-malarials were mainly found in the private outlets (38.9%) compared to public (4.2%) and NGO (0%) outlets. The median price of a course of AS-AQ was US$0.16 (200 Burundi Francs, FBu) for the public and NGO markets, and 3.5-fold higher in the private sector (US$0.56 or 700 FBu). Quinine tablets were similarly priced in the public (US$1.53 or 1,892.50 FBu), private and NGO sectors (both US$1.61 or 2,000 FBu). Non-policy anti-malarials were priced 50-fold higher than the price of AS-AQ in the public sector. A course of AS-AQ was affordable at 0.4 of a day's wage in the public and NGO sectors, whereas, it was equivalent to 1.5 days worth

The objective of this population-based cross-sectional study was to estimate rural-urban disparity in the oral health-related quality of life (OHRQoL) of the Quebec adult population. A 2-stage sampling design was used to collect data from the 1788 parents/caregivers of schoolchildren living in the 8 regions of the province of Quebec in Canada. Andersen's behavioural model for health services utilization was used as a conceptual framework. Place of residency was defined according to the Statistics Canada Census Metropolitan Area and Census Agglomeration Influenced Zone classification. The outcome of interest was OHRQoL measured using the Oral Health Impact Profile (OHIP)-14 validated questionnaire. Data weighting was applied, and the prevalence, extent and severity of negative oral health impacts were calculated. Statistical analyses included descriptive statistics, bivariate analyses and binary logistic regression. The prevalence of poor oral health-related quality life (OHRQoL) was statistically higher in rural areas than in urban zones (P = .02). Rural residents reported a significantly higher prevalence of negative daily-life impacts in pain, psychological discomfort and social disability OHIP domains (P < .05). Additionally, the rural population showed a greater number of negative oral health impacts (P = .03). There was no significant rural-urban difference in the severity of poor oral health. Logistic regression indicated that the prevalence of poor OHRQoL was significantly related to place of residency (OR = 1.6; 95% CI = 1.1-2.5; P = .022), perceived oral health (OR = 9.4; 95% CI = 5.7-15.5; P < .001), dental treatment needs factors (perceived need for dental treatment, pain, dental care seeking) (OR = 8.7; 95% CI = 4.8-15.6; P < .001) and education (OR = 2.7; 95% CI = 1.8-3.9; P < .001). The results of this study suggest a potential difference in OHRQoL of Quebec rural and urban populations, and a need to develop strategies to promote oral health outcomes
Full Text Available Abstract Parenteral artesunate has been shown to be a superior treatment option compared to parenteral quinine in adults and children with severe malaria. Little evidence, however, is available on long-term safety. Recently, cases of late-onset haemolysis after parenteral treatment with artesunate have been reported in European travellers with imported Plasmodium falciparum malaria. Therefore, an extended follow-up of adult patients treated for severe imported malaria was started in August 2011 at the University Medical Center Hamburg-Eppendorf. Until January 2012, three patients with hyperparasitaemia (range: 14-21% were included for analysis. In all three patients, delayed haemolysis was detected in the second week after the first dose of intravenous artesunate. Reticulocyte production index remained inadequately low in the 7 – 14 days following the first dose of artesunate despite rapid parasite clearance. Post-treatment haemolysis after parenteral artesunate may be of clinical relevance in particular in imported severe malaria characterized by high parasite levels. Extended follow-up of at least 30 days including controls of haematological parameters after artesunate treatment seems to be indicated. Further investigations are needed to assess frequency and pathophysiological background of this complication.
Full Text Available Objective: The aim of this study is to determine the oral health related quality of life and the effect of dental anxiety on the oral health related quality of life in young, mildly intellectually disabled individuals who are attending a special school. Materials and Methods: Eighty six mildly intellectually disabled students participated this cross-sectional study. Oral health-related quality of life-United Kingdom Scale and Oral Health Impact Profile-14 were used to evaluate the effects of oral health of the individuals on their quality of life. Modified Dental Anxiety Scale was used to determine the dental anxiety levels of the individuals. Data were analyzed statistically. Results: The mean age of the participants was 17.12±1.40 years and the mean decayed, missing, and filled teeth (DMFT score of the students was 3.10±2.76. According to the Modified Dental Anxiety Scale, 28.0% of the students had dental anxiety. A significant inverse relationship was detected between dental anxiety levels and oral health-related quality of life (r=-0.239; p=0.028. Conclusion: Nearly 30% of individuals with mild intellectual disabilities were determined to have dental anxiety. Considering that the oral health-related quality of life decreases with increasing dental anxiety, it may be beneficial for dentists to administer premedication before treatment to decrease the anxiety levels of these patients.

Despite the important role of the antimalarial artesunate and its active metabolite dihydroartemisinin (DHA) in malaria treatment efforts, there are limited data on the pharmacokinetics of these agents in pediatric patients. This study evaluated the effects of body size and gender on the pharmacokinetics of artesunate-DHA using data from pediatric and adult malaria patients. Nonlinear mixed-effects modeling was used to obtain a base model consisting of first-order artesunate absorption and on...

Abstract Dental diseases such as dental caries and periodontal disease could well be seen as being behaviour-related. The high prevalence of periodontal disease in the Finnish adult population mirrors the need for improving oral health behaviours in a comprehensive manner. Thus far, scant attention has been drawn to the underlying psycho-social factors that could, in part, explain oral health and oral health behaviours. Deficiencies in oral health behaviour may also be indicative of an ind...

The effect of periodontal surgery on patients' quality of life was investigated. Sixty patients received regenerative surgery or resective osseous surgery. Oral health-related quality of life and health-related quality of life instruments were used to assess the participants' quality of life before surgery and 4 weeks after surgery. Periodontal surgery can improve patients' quality of life by alleviating the physical pain and psychological discomfort. The scores were lower (more favorable) in the regenerative surgery group, and the functional limitations of the regenerative surgery group improved substantially compared with those of the resective osseous surgery group (P = 0.0421). The patients' oral health-related quality of life scores improved significantly after periodontal surgery. Clinicians can take advantage of the positive functional oral health-related quality of life impacts of regenerative surgery. Copyright © 2017. Published by Elsevier Taiwan.

The goal set by the French highest national authorities in the 2014-2019 Cancer Plan is to "heal more sick persons by promoting early diagnosis through screening". Screening requires information. Nowadays, Internet allows for access to information "in one click". The aim of our study was to evaluate the quality of information found on the Internet. Several sites dedicated to oral cavity cancer screening were selected on Google. The quality of health information found in these sites was evaluated by the DISCERN questionnaire. The quality of decision support provided by the sites was evaluated by the IPDAS checklist. Twenty-seven sites were selected. The average DISCERN score was 25.1/75 (15/75 to 40/75). Eighteen sites (66.6%) had very poor, 8 sites (29.6%) had poor and 1 site had average information quality. IPDAS scores ranged from 11.1 to 38.1. Eight sites (29.6%) had less than 20%, 14 sites (51.9%) had between 20 and 30% and 5 sites (18.5%) had 30% or more validated criteria. No site achieved the pass mark. The quality of general public French-speaking website dedicated to oral cancer detection is very bad. The role of health professionals such as general practitioners and head and neck surgeons, remains essential. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Full Text Available Artemisinin and its derivates are an important class of antimalarial drug and are described to possess immunomodulatory activities. Few studies have addressed the effect of artesunate in the murine malaria model or its effect on host immune response during malaria infection. Herein, we study the effect of artesunate treatment and describe an auxiliary mechanism of artesunate in modulating the inflammatory response during experimental malaria infection in mice. Treatment with artesunate did not reduce significantly the parasitemia within 12 h, however, reduced BBB breakdown and TNF-α mRNA expression in the brain tissue of artesunate-treated mice. Conversely, mefloquine treatment was not able to alter clinical features. Notably, artesunate pretreatment failed to modulate the expression of LFA-1 in splenocytes stimulated with parasitized red blood cells (pRBCs in vitro; however, it abrogated the expression of ICAM-1 in pRBC-stimulated endothelial cells. Accordingly, a cytoadherence in vitro assay demonstrated that pRBCs did not adhere to artesunate-treated vascular endothelial cells. In addition, NF-κB nuclear translocation in endothelial cells stimulated with pRBCs was impaired by artesunate treatment. Our results suggest that artesunate is able to exert a protective effect against the P. berghei-induced inflammatory response by inhibiting NF-κB nuclear translocation and the subsequent expression of ICAM-1.

The objective of this study was to assess the oral health-related quality of life between the parents and the teachers of disabled schoolchildren in Kuwait. The three category response version of the General Oral Health Assessment Index (GOHAI) (12 questions, always, sometimes, never) was used in the questionnaires in Kuwait. Three hundred and eight (308) parents and 112 teachers were enrolled in this study. The mean age of the parents was 45 ± 9.9 years and of the teachers 38 ± 8.4 years. The mean GOHAI was 27.2 ± 3.5 among the parents and 27.8 ± 3.3 among the teachers (p = 0.091). GOHAI was higher in the older age groups (p = 0.002) and among the parents with a university education (p < 0.001). GOHAI was also higher with increasing toothbrushing frequency among the parents (p = 0.047) and the teachers (p = 0.003). Altogether, 203 (66%) of the parents and 85 (76%) of the teachers were always able to swallow comfortably; 123 (40%) of the parents and 41 (37%) of the teachers were able to eat without discomfort. Overall, 132 (43%) of the parents and 41 (37%) of the teachers were always pleased and happy with the looks of their teeth and gums, or dentures. The Cronbach's alpha (0.83) indicated a high degree of internal consistency between different GOHAI items. There seemed to be no difference in the impact of oral health on the quality of life between the parents and the teachers of disabled schoolchildren. Oral health had a relatively weak impact on the quality of life of these adults. Copyright © 2012 S. Karger AG, Basel.

Background Recent research has suggested that chronic dry mouth affects the day-to-day lives of older people living in institutions. The condition has usually been considered to be a feature of old age, but recent work by our team produced the somewhat surprising finding that 10% of people in their early thirties are affected. This raises the issue of whether dry mouth is a trivial condition or a more substantial threat to quality of life among younger people. The objective of this study was to examine the association between xerostomia and oral-health-related quality of life among young adults while controlling for clinical oral health status and other potential confounding factors. Methods Cross-sectional analysis of data from a longstanding prospective observational study of a Dunedin (New Zealand) birth cohort: clinical dental examinations and questionnaires were used at age 32. The main measures were xerostomia (the subjective feeling of dry mouth, measured with a single question) and oral-health-related quality of life (OHRQoL) measured using the short-form Oral Health Impact Profile (OHIP-14). Results Of the 923 participants (48.9% female), one in ten were categorised as 'xerostomic', with no apparent gender difference. There was a strong association between xerostomia and OHRQoL (across all OHIP-14 domains) which persisted after multivariate analysis to control for clinical characteristics, gender, smoking status and personality characteristics (negative emotionality and positive emotionality). Conclusion Xerostomia is not a trivial condition; it appears to have marked and consistent effects on sufferers' day-to-day lives. PMID:17090332

Full Text Available Abstract: The aim of the present study was to compare negative impacts of oral conditions in Oral Heath Related Quality of Life (OHRQoL assessed by the Oral Health Impact Profile-14 (OHIP-14 scores in pregnant women receiving or not comprehensive periodontal treatment. This randomized controlled clinical trial included pregnant women aged between 18 and 35 years old. Participants were randomized in a test group with 96 and a control group with 114 women. Patients in the test group received comprehensive periodontal treatment, supra and subgingival scaling and root-planning and periodontal maintenance appointments. The OHIP-14 was applied before and after treatment. The primary outcome was changes in OHIP-14 scores after follow-up period. The impact of having received or not comprehensive periodontal treatment on the change of the OHIP-14 scores was also investigated. Both groups showed significant reduction in OHIP-14 scores and effect size for the test group was 0.60 and 0.36 for the control group. Multinomial logistic regression analysis showed that participants of the control group had 5.9-fold odds (CI 95% 1.88-18.52 of worsening in OHIP-14 scores and their perception of oral conditions in relation to test group. Comprehensive periodontal treatment during pregnancy can reduce the negative impacts in OHRQoL.

Health-related quality of life (HRQL) data are becoming an important supplement to information pertaining to treatment outcome for cancer patients. The purpose of this study was to evaluate the HRQL outcome for oral cancer survivors after surgery plus postoperative radiotherapy (RT) and to investigate the variables associated with their HRQL. Sixty-six oral cancer patients with cancer-free survival after surgery plus postoperative RT of >2 years were enrolled. The Short Form-36 (SF-36) questionnaire in the Taiwan Chinese version was self-reported by all participants at the clinics. The linear regression model was used to analyze the socio-demographic and medical-related variables correlated with the physical component summary (PCS) and mental component summary (MCS) in SF-36. The mean scores of the eight functional domains in the SF-36 were markedly lower for oral cancer survivors compared with the Taiwanese and US norms. Those with older age, lower annual family income, more advanced cancer stage and flap reconstruction had significantly worse PCS, and those with lower annual family income, unemployment and more advanced cancer stage reported significantly worse MCS. This model accounts for 63% of variance in PCS, and 51% in MCS. These results provided patient-reported evidence that oral cancer survivors lived with a worse HRQL compared with the general Taiwanese population. Socio-economic factors and cancer stage were important factors correlated with their HRQL. (authors)
Full Text Available Background/Aim. Tooth loss affects oral health-related life quality. More than a third of edentulous patients are not fully satisfied with their complete dentures and mainly complain of insufficient stability, retention, and pain during mastication. Solving the problem may include relining by materials that are based on silicone or acrylic. The aim of this study was to determine the level of patients’ satisfaction before and after relining upper dentures with soft and rigid liners. Methods. The patients (n = 24 were divided into two study groups. Maxillary denture relining of the first group of patients was performed with hard acrylic based resins while in the second group of patients complete denture was relined with a silicone-based soft liner. They were asked the questions from the specifically adapted the Oral Health Impact Profile Questionnaire for edentulous patients before and three months after relining dentures. Results. After relining the patients showed a higher degree of satisfaction with their dentures in all the tested domains (masticatory function, psychological discomfort, social disability and retention and hygiene. The patients with soft denture relines were more satisfied. Conclusion. Relining of maxillary complete dentures significantly positively impacts the quality of life of patients in all the tested domains (masticatory function, psychological discomfort, social disability, pain and oral hygiene. Better results were achieved using a silicone-based soft liner, which recommends it as the material of choice for relining dentures.

Health-related quality of life (HR-QoL) informations are becoming an important tool for the treatment concept for cancer patients. The purpose of this study was to evaluate how the quality of life depends on the disease severity of pre- and oral cancer patients and which factors influence their quality of life. During this study, 106 patients with a premalignant oral lesion, 174 patients with oral squamous cell carcinoma (OSSC) as well as 21 patients with a recurrence of OSSC were asked about their oral health-related quality of life. Additionally, the UW-QOLv4 was used to record the psychological and clinical symptoms from which the patients of the three groups are suffering. Significant differences with respect to oral HR-QoL of life between the groups could be evaluated. Patients with a recurrence have the lowest and patients with precancer the highest HR-QoL. Within the groups, there is a difference regarding the significance of the psychological factors. The lowest values were achieved for mood within all three groups. Anxiety is of key importance for the precancer group whereas appearance and activity are of importance for the patients having a tumor. The patients of the recurrence group are heavily affected by all factors. The quality of life differs depending on the disease. The patients of the recurrence group have the lowest oral health-related quality of life for all aspects analyzed, and they are suffering the most with respect to the psychological dimensions of the UW-QOLv4. The present study examined the quality of life depending on the severity of the disease of pre- and oral cancer patients and which factors significantly influenced their quality of life. The evaluated findings of relevant variables may have therapeutic relevance for the multidisciplinary treatment of oral cancer patients in the future.

Oral lichen planus (OLP) is a chronic, multifocal, sometimes painful, inflammatory disease of the oral mucosa. OLP can predispose development of psycho-emotional disorders. Until now, the relationship between the severity of lichen planus and the psychological profile of patients (psychological well-being, perceived stress and pain coping strategies) has never been studied. Study was conducted on 42 OLP patients. Number of sites involved, severity and activity score of OLP were evaluated. Psychological tests were used to evaluate patients' psycho-emotional condition. The mean duration time of symptomatic OLP was 43 months. We detected that the longer the duration of subjective symptoms, the poorer the quality of life and the higher the level of perceived stress (PSS). Also, the higher the PSS results, the greater the anxiety and depression on Hospital Anxiety and Depression Scale (HADS). Likewise, higher level of depression in HADS was strongly correlated with worse quality of life. (p≤0.05). In this study, we detected a relationship between duration of the disease, level of perceived stress and quality of life. The longer the disease lasts, the higher it tends to catastrophize. This may influence development or increase of the anxiety and depression and may decrease patients' quality of life.

Abstract Objectives Oral lichen planus (OLP) is a chronic, multifocal, sometimes painful, inflammatory disease of the oral mucosa. OLP can predispose development of psycho-emotional disorders. Until now, the relationship between the severity of lichen planus and the psychological profile of patients (psychological well-being, perceived stress and pain coping strategies) has never been studied. Material and Methods Study was conducted on 42 OLP patients. Number of sites involved, severity and activity score of OLP were evaluated. Psychological tests were used to evaluate patients’ psycho-emotional condition. The mean duration time of symptomatic OLP was 43 months. Results We detected that the longer the duration of subjective symptoms, the poorer the quality of life and the higher the level of perceived stress (PSS). Also, the higher the PSS results, the greater the anxiety and depression on Hospital Anxiety and Depression Scale (HADS). Likewise, higher level of depression in HADS was strongly correlated with worse quality of life. (p≤0.05). Conclusions In this study, we detected a relationship between duration of the disease, level of perceived stress and quality of life. The longer the disease lasts, the higher it tends to catastrophize. This may influence development or increase of the anxiety and depression and may decrease patients’ quality of life. PMID:29364344

To assess the hierarchical associations between children's school performance and condition-specific (CS) oral health-related quality of life (OHRQoL), school absence, oral status, sociodemographic and economic status (SDES) and social capital; and to investigate the associations between CS OHRQoL and related oral status, adjusting for SDES and social capital. Data on 925 sixth grade children in Sakaeo province, Thailand, were collected through oral examinations for dental caries and oral hygiene, social capital questionnaires, OHRQoL interviews using the Child-Oral Impacts on Daily Performances index, parental self-administered questionnaires and school documents. A hierarchical conceptual framework was developed, and independent variables were hierarchically entered into multiple logistic models for CS OHRQoL and linear regression models for school performance. After adjusting for SDES and social capital, children with high DMFT or DT scores were significantly threefold more likely to have CS impacts attributed to dental caries. However, poor oral hygiene was not significantly associated with CS impacts attributed to gingival disease. High DMFT scores were significantly associated with lower school performance, whereas high Simplified Oral Hygiene Index scores were not. The final model showed that CS impacts attributed to dental caries and school absence accounted for the association between DMFT score and school performance. Dental caries was associated with CS impacts on OHRQoL, and exerted its effect on school performance through the CS impacts and school absence. There was no association between oral hygiene and CS impacts on OHRQoL or school performance. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background Since 1998 the serious public health problem in South East Asia of counterfeit artesunate, containing no or subtherapeutic amounts of the active antimalarial ingredient, has led to deaths from untreated malaria, reduced confidence in this vital drug, large economic losses for the legitimate manufacturers, and concerns that artemisinin resistance might be engendered. Methods and Findings With evidence of a deteriorating situation, a group of police, criminal analysts, chemists, palynologists, and health workers collaborated to determine the source of these counterfeits under the auspices of the International Criminal Police Organization (INTERPOL) and the Western Pacific World Health Organization Regional Office. A total of 391 samples of genuine and counterfeit artesunate collected in Vietnam (75), Cambodia (48), Lao PDR (115), Myanmar (Burma) (137) and the Thai/Myanmar border (16), were available for analysis. Sixteen different fake hologram types were identified. High-performance liquid chromatography and/or mass spectrometry confirmed that all specimens thought to be counterfeit (195/391, 49.9%) on the basis of packaging contained no or small quantities of artesunate (up to 12 mg per tablet as opposed to ∼ 50 mg per genuine tablet). Chemical analysis demonstrated a wide diversity of wrong active ingredients, including banned pharmaceuticals, such as metamizole, and safrole, a carcinogen, and raw material for manufacture of methylenedioxymethamphetamine (‘ecstasy'). Evidence from chemical, mineralogical, biological, and packaging analysis suggested that at least some of the counterfeits were manufactured in southeast People's Republic of China. This evidence prompted the Chinese Government to act quickly against the criminal traders with arrests and seizures. Conclusions An international multi-disciplinary group obtained evidence that some of the counterfeit artesunate was manufactured in China, and this prompted a criminal investigation
Background Intravenous (IV) artesunate is the treatment of choice for severe malaria. In Europe, this treatment is only available in a few countries via named patient programmes (NPPs). As a case study, the legal and organisational aspects and pharmacovigilance of these NPPs and possibilities for harmonisation within the EU were studied over time and space using IV artesunate (Malacef) in the Netherlands, Belgium and France. Methods The legal base and organisation of NPPs in the Netherlands, Belgium and France were studied. The diffusion and cumulative availability of IV artesunate and the pharmacovigilance components were compared among the three countries using distribution data from the period 2007 through 2012. Results Artesunate has quickly gained acceptance for treating severe malaria in the Netherlands, whereas both Belgium and France have introduced this treatment more hesitantly. This difference in acceptance is due to differences in the implementation of NPP legislation among the countries. France currently has a proactive system in which treatment requires the permission for each patient and an intensive follow-up protocol. On the other hand, Belgium and Dutch NPPs are more dependent on the investigators’ initiative and are therefore potentially faster and more flexible, facilitating the discovery of adverse effects that have not been reported by more formal comparative clinical trials. Conclusions NPPs provide a unique opportunity to study both the benefits and risks of unregistered products for treating rare diseases, provided that the patients are actively vigilated. Thus, we recommend that NPPs should be harmonised throughout Europe in order to ensure equal availability of treatment and therapeutic benefit to all Europeans without compromising patient safety.

Full Text Available This cross-sectional study assessed the impact of Developmental Enamel Defects (DED on Child Oral Health-Related Quality of Life (COHRQoL. A sample of 944 11- to 14-year-old Brazilian schoolchildren was examined for the prevalence and severity of DED. The children completed the Child Perceptions Questionnaire (CPQ11-14, and socioeconomic status was also collected using a questionnaire. Poisson regression models were used to assess the association between DED and overall and domain-specific CPQ11-14 scores. The prevalence of DED was 19.7%. In general, children with DED did not indicate any decrease in self-perception. However, this condition was associated with an impact on the functional limitation domain. The presence of DED may cause negative impacts on a child's perception of oral health and on their daily performance.
Full Text Available Context: Currently there is a growing interest in oral health outcomes in how oral health affects quality of life. When oral health related quality of life measures are used alongside traditional clinical methods of measuring oral health status, a more comprehensive assessment of the impact of oral diseases on the several dimensions of subjective wellbeing becomes possible. In this context, we attempted to study the impact of oral diseases on quality of life, so as to address the patient′s needs in an appropriate way and thereby improving one′s quality of life. Aims: To evaluate the impact of different oral diseases on quality of life using a modified OHIP-14 questionnaire, so as to address the patient′s needs in an appropriate way and thereby improving one′s quality of life. Settings and Design: The study was carried out among 302 subjects, attending the outpatient department a dental hospital, India, for check up and treatment of their oral condition. Subjects aged above 20 years, who gave their consent for the study were included. Materials and Methods: The study sample was categorized in to two groups based upon the duration of the affecting disease - group 1 consisted of subjects suffering with chronic diseases and group 2 of subjects suffering with acute diseases. All the subjects were asked to fill up their responses in the given OHIP-14 questionnaires. The completed questionnaires were then collected and statistically analyzed. Statistical Analysis Used: To evaluate the role of age on QOL, age was divided in to 2 groups using median split procedure. For inter and intragroup comparisions, independent sample t test, anova followed by post hoc test and Chi-square tests were employed. Results: Chi square test revealed a moderately impaired quality of life among all the diseases investigated. On comparing the mean domain and total OHIP score between the two groups, the domain of psychological discomfort and disability and the total

Removable partial dentures (RPDs) represent standard treatment for partial edentulism despite major shortcomings. To alleviate these shortcomings, endosseous implants provide support and stability as well as contribute to maintenance of alveolar bone. This prospective, within subject, time series study evaluated patient-based outcomes of RPDs compared to implant-supported removable partial dentures (ISRPDs). The study hypothesis was that the ISRPD would substantially improve oral health quality of life for patients. Seventeen patients requesting new mandibular Kennedy I or II RPDs received one 6-mm dental implant in one or both of the posterior edentulous areas. After healing, conventional RPDs were fabricated and delivered. Twelve weeks later, second-stage surgery was performed, and ball abutments with Clix attachments were inserted, thereby converting the prostheses to ISRPDs. Oral health quality of life was evaluated using the 49-item Oral Health Impact Profile (OHIP-49) questionnaire. The OHIP-49 was administered prior to treatment (baseline), at 6 and 12 weeks following RPD delivery and at 6 and 12 weeks following ISRPD conversion. Radiographic evaluation was performed at 6 and 12 weeks following ISRPD conversion. In statistical analysis, a fixed-slope random intercept variance components model took account of the multiple observations per person over time. In 17 subjects, 29 of 30 implants survived. The failed implant was replaced without complications. Abutment complications were limited to one abutment loosening and one attachment replacement. Minor prosthodontic complications were recorded. The OHIP-49 score reduced by 11.8 points, on average, at 12 weeks following ISRPD conversion (P = 0.011). Patients reported improved oral health following conversion to an ISRPD from RPD. The ISRPD involving short implants is one treatment option that should be considered when treatment planning Kennedy Class I and II patients. © 2012 John Wiley & Sons A/S.

Full Text Available Inter-relationships between traditional dental variables are becoming more evident in far reaching aspects of life, such as psychosocial interaction, self-esteem, overall health and even occupational performance. This study compares quality of life (QoL in postmenopausal women (PMW with poor oral health (POH with QoL in PMW with good oral health. A total of 200 randomly recruited PMW received a dental evaluation and completed the Utian Quality of Life Survey. The participants were divided into POH and healthy groups based on a dental exam. Mean scores were calculated for each QoL item, domain and the overall summary score. For each of the four parameters for periodontitis diagnosis, periodontitis b s patients’ QoL outcomes were compared to those of healthy patients using a T-test with a threshold of significance at p < 0.05. QoL in all fields measured was significantly poorer in the POH patients compared to the healthy patients: occupational score (19.95 ± 5.35 vs. 27.56 ± 6.13, health score (18.02 ± 8.23 vs. 26.59 ± 6.45, emotional score (15.68 ± 10.22 vs. 21.15 ± 9.15, sexual score (6.2 ± 5.98 vs. 10.02 ± 5.35, and total score (60.21 ± 25.85 vs. 84.26 ± 22.35. This study finds that PMW with POH report significantly poorer quality of life. Clinicians caring for PMW should be aware that oral health impacts QoL and make appropriate referral decisions for patients’ dental care.

Our objective was to determine the effects of peridialytic oral supplements on nutritional markers and quality of life (QOL) in patients receiving maintenance hemodialysis. This trial was open, prospective, nonrandomized, and comparative. This study was performed at an outpatient hemodialysis unit in a teaching hospital. This study included 88 adults with chronic kidney disease at stage 5. This study involved directly observed nutrition therapy with >or=1 can of enteral nutrition (Nepro) with each hemodialysis session thrice weekly for 3 months, or standard care. Changes in biochemical markers of nutritional status and QOL, as measured by the Kidney Disease Quality of Life-Short Form, were determined. Peridialytic oral nutrition resulted in a significant difference between the nutrition and comparison groups in serum albumin change over time (P = .03; repeated-measures analysis of variance with covariates). Mean (+/-SD) serum albumin concentration did not differ between baseline and month 3 in the nutrition group (3.68 +/- 0.33 g/dL vs. 3.75 +/- 0.40 g/dL; P = .12), but in the comparison group, serum albumin levels declined significantly (3.93 +/- 0.34 g/dL at baseline versus 3.81 +/- 0.37 g/dL at month 3; P = .04). The "role-physical" domain score of the Kidney Disease Quality of Life-Short Form significantly changed over time in the nutrition group versus the comparison group (P = .02; repeated-measures analysis of variance with covariates). Nepro was well-tolerated, and greater than 80% of the prescribed therapy was consumed. Oral nutrition, as part of structured, directly observed peridialytic therapy in chronic hemodialysis patients, was well-accepted, and resulted in the maintenance of serum albumin levels and QOL with respect to impact of physical health on daily activities. These findings need to be confirmed in a randomized, controlled trial.

Full Text Available Introduction: To determine the impact of oral diseases on everyday life, measures of oral quality of life are needed. In complementing traditional disease-based measures, they assess the need for oral care to evaluate oral healthcare programs and management of treatment. Aim: To evaluate the oral health-related quality of life (OHRQOL among professional college students. Materials and Methods: A cross-sectional study was conducted to measure the OHRQOL of 940 students (males: 425, females: 515 from six different professions (medical, dental, engineering, pharmacy, physiotherapy, and master of business administration of Nellore, Andhra Pradesh, using a 14-item Oral Health Impact Profile-14 (OHIP-14 questionnaire. The data were analyzed using statistical analysis system to perform the Chi-square test and Kruskal–Wallis test. Results: The mean OHIP scores for medical, dental, pharmacy, physiotherapy, engineering, and MBA students were 5.2, 3.5, 3.2, 3.0, 3.6, and 2.8, respectively. The overall OHIP-14 score showed a significant statistical difference (P < 0.05 from medical students to remaining study population. Conclusion: There is much significant difference in OHRQOL in different professional students. Oral health-care providers are urged to integrate the OHRQOL concept into their daily practice to improve the outcome of their services as it provides the basis for any oral health program development.

Full Text Available Abstract Background Oral health-related quality of life (OHQoL is conceived as a multidimensional construct. Here our aim was to investigate the dimensional structure of OHQoL as measured by the Spanish versions of the Oral Impacts on Daily Performance (OIDP and the Oral Health Impact Profile (OHIP-14 questionnaires applied simultaneously. Methods We recruited a consecutive sample of 270 healthy Spanish workers visiting the Employment Risk Prevention Centre for a routine medical check-up. OHIP-14 was self-completed by participants but the OIDP was completed in face-to-face interviews. An Exploratory Factor Analysis (EFA was performed to identify the underlying dimensions of the OHQoL construct assessed by both instruments. This factorial structure was later confirmed by Confirmatory Factor Analysis (CFA using several estimators of goodness of fit indices. Results EFA and the CFA identified and respectively confirmed a set of 3 underlying factors in both questionnaires that could be interpreted as functional limitation, pain-discomfort, and psychosocial impacts. The model achieved was seen to fit properly for both instruments, but the factorial structure was clearer for the OIDP. Conclusions The results provide evidence for construct equivalence in the latent factors assessed by both OIDP and OHIP-14, suggesting that OHQoL is a three-dimensional construct. The prevalence of impact on these three factors was coherent between both indicators, pain-discomfort having the highest prevalence, followed by psycho-social impact, and functional limitation.

This study aims to assess and compare Oral Health-Related Quality of Life (OHRQoL) in child abuse victims and non-abused children in a Southern Brazilian city. The study compared two independent samples of children aged 8-10 years: 48 child abuse victims recruited from a centre for Child and Adolescent Psychological Support (NACA) for abused children, and 144 public and private school students. Data collection consisted of administration of the Child Perceptions Questionnaire 8-10 (CPQ 8-10 ) to measure OHRQoL (dependent variable), clinical examination (dental caries), and collection of socioeconomic and demographic information (age, sex, skin colour, family income, and type of school). Multiple linear regression models were used to assess the association between presence of abuse and OHRQoL and subscales. After adjustment for clinical and sociodemographic variables, child abuse victims were found to exhibit higher CPQ scores on the overall scale and on the oral symptoms and functional limitations subscales. In conclusion, child abuse victims have a higher impact on OHRQoL. Based on the results, it is possible to suggest that greater care should be taken of these children, not only in providing treatment for oral disorders, but also in providing interdisciplinary care.

The study objective was to compare children's oral health related quality of life (OHRQoL) in schools with 6 years of implementation of a health promoting school model in Malaysia, i.e. the Doktor Muda Programme (DMP) and in schools without the DMP. This report was part of a larger study to evaluate the DMP impact on schoolchildren's oral health knowledge, attitudes, behaviour, caries progression and OHRQoL. It was conducted in Negri Sembilan state. The sample comprised 3455, Year 6 (11-12 year old) children; 1282 from DMP (intervention) and 2173 from non-DMP (control) schools. The Malay Child-OIDP index was used to evaluate children's levels of oral impacts on 8 daily performances after 6 years of DMP implementation (2006-2011). Prevalence, score, impact intensity, causes and extent of impacts were compared. Chi-square and Mann-Whitney tests were used in the data analysis. Overall response rate was 95.1%. Prevalence of overall impacts was 57.8% and 60.8% (mean total impact score was 7.10 and 7.77) in the intervention and control group, respectively. The three most frequently affected performances in both groups were eating, cleaning teeth and emotional stability. Significantly less DMP children had oral impact on cleaning teeth (p = 0.034). The majority of children with impacts in both groups reported 'very little' to 'moderate' levels of impact intensity. Significantly more DMP children reported having 'very little' and 'little' levels of impact intensity on cleaning teeth (p = 0.037) and emotional stability (p = 0.020), respectively. Significantly less DMP children reported having 'very severe' level of impact intensity on speaking (p = 0.038). The most prevalent cause of impacts in both groups was toothache. Significantly less DMP children reported bleeding gums (p = 0.016) and presence of plaque/calculus as causes of impacts (p = 0.032). About 75% of children with impacts in both groups reported having up to four daily performances affected. This study showed

There is no study on the association between oral health education and oral health quality of life (OHQoL). To assess the relationship between oral health education activities integrated into primary care services and OHQoL in adolescents. A retrospective observational survey was conducted on 300 randomly selected 12-14 years-of-age adolescents living in two publicly funded health service administrative areas in Manaus, Brazil. Between 2006 and 2008, dental treatment and oral health education were offered in one area (DT/OHE group), whereas in the other area, only dental treatment was provided (DT group). Collected data included socio-demographic characteristics, health services use, health-related behaviours, dental pain, dental caries and Child-OIDP. Independent variables were compared between groups by Mann-Whitney and chi-square tests. The association between one or more OIDP (Child-OIDP ≥ 1) and DT group tested using multivariate logistic regression. Caries, use of dental services and health-related behaviours did not differ between groups (P > 0.05). Child-OIDP ≥ 1 was higher in DT group (90.0%) compared with DT/OHE group (79.3%) (P = 0.01). Child-OIDP ≥ 1 was independently associated with DT group [OR = 4.4 (1.1; 17.0)]. Adolescents living in an area where OHE and DT were provided had better OHRQoL than those living in an area where only DT was provided. © 2012 John Wiley & Sons Ltd, BSPD and IAPD.

Full Text Available Abstract Background Treatment with oral anticoagulant may influence the quality of life perception as it promotes changes in the patient's life, not offering an evident symptomatic relief and presenting well defined risks, such as bleeding. In this trial, the influence of chronic use of anticoagulants on the quality of life perception has been analyzed in patients assisted at the anticoagulation outpatient unit. Methods The health related quality of life was evaluated through a cross-section study with a sample composed of 72 patients seen from July 23, 2009 to September 2, 2010 at the Anticoagulation Outpatient Unit of the Federal University of Bahia's University Hospital. The study's population was composed by patients with atrial fibrillation and mechanical heart valve. The patients were submitted to two quality of life evaluation questionnaires: a generic questionnaire - the Medical Outcomes Study SF-36 Health Survey (SF36 - and a specific questionnaire - the Duke Anticoagulation Satisfaction Scale (DASS. Results The quality of life perception of the patients studied, based on both the DASS and the SF36, was positive regarding the treatment with oral anticoagulant. The SF36 presented an average score of 62.2 (± 20.0. Among the SF36 evaluated domains, the physical-emotional aspect was the most compromised one regarding life quality perception. The DASS presented an average score of 67.1 (± 18.2 and the domain presenting a greater compromise was the one related to the treatment inconveniences (annoyances, burdens and obligations. Previous hemorrhagic event, comorbidities, drug interactions with medicines that increase the anticoagulant effect, lower education level in the SF36 and younger age group influence a more negative perception of the quality of life, whereas lower education level in the DASS and the duration of treatment for more than 1 year offer a more positive perception. Conclusion Patients seen at the anticoagulation outpatient

Purpose: To assess the quality of life (QOL) of oral cancer patients treated with low-dose-rate interstitial brachytherapy (LDR-BT) alone. Methods and Materials: Between June 2005 and July 2006, a total of 56 patients with oral cancer were enrolled in this prospective study. QOL was assessed by means of the core questionnaire and head and neck questionnaire module of the European Organization for Research and Treatment of Cancer (EORTC Quality of Life Questionnaire-Core 30 [QLQ-C30] and QLQ Head and Neck 35 [H and N35]). The questionnaires were distributed to the patients before the start of treatment and 3 months, 6 months, and 12 months after the start of LDR-BT. Results: It was possible to analyze the results for 20 of the initial 56 patients because they did not experience metastasis or recurrence during this study. No functions or symptoms asked about in the QLQ-C30 deteriorated during the first year. The emotional function score steadily and significantly increased. No symptoms in the QLQ-H and N35 significantly deteriorated. The scores for pain, trouble with social eating, and weight loss on the QLQ-H and N35 steadily and significantly decreased. Age, gender, and LDR-BT source had no effect on the change in QOL during the first year, but T-stage significantly affected the change in global health status, tumor site affected the changes in swallowing, sensory problems, sticky saliva, and complications affected the changes in pain, swallowing, and mouth opening. Conclusions: QOL of oral cancer patients treated with LDR-BT is high. However, tumor stage, tumor site, and complications affected the changes in a few functions and symptoms during the first year

The purpose of this cross-sectional study was to investigate the effect of different forms of periodontal diseases on Oral Health-Related Quality of Life (OHRQoL). Fifty-two patients with Aggressive Periodontitis (AP) or Chronic Periodontitis (CP) were included: nine patients with Localized Aggressive Periodontitis (LAP), thirty-three patients with Generalized Aggressive Periodontitis (GAP) and ten patients with Generalized Chronic Periodontitis (GCP). Oral Health Impact Profile questionnaires (OHIP-14) were distributed after a clinical examination that measured the following periodontal parameters: tooth loss, bleeding on probing (BoP), probing depth (PD), gingival recession (REC) and clinical attachment level (CAL). The global OHIP-14 score means were 10.6 for LAP, 16.5 for GAP, and 17.5 for GCP. A statistically significant difference (p periodontitis. LAP, GAP and GCP have an impact on patient quality of life when measured using the OHIP-14. Patients with GAP and GCP had poorer OHRQoL than LAP patients.
Full Text Available Background: Children with autism present with the physical-mental impairments and oral problems, which may have an impact on their quality-of-life (QoL. The aim of the following study was to assess oral health status and parental perception of child oral health related quality of life (OHRQoL among children with autism. Materials and Methods: A cross-sectional study was conducted in 4-15-year-old children with autism (n = 135 and children without autism (n = 135. Oral health status was evaluated using Oral Hygiene Index-Simplified (OHI-S, its Miglani′s modification for deciduous teeth, Decayed, missing and filled teeth (DMFT/dmft and Decayed, missing and filled surface (DMFS/dmfs indices. Parents answered the Parental-Caregivers Perception Questionnaire for assessing children′s OHRQoL. Mann-Whitney U, Chi-square test and Pearson′s correlation analysis were performed. Results: Mean OHI-S, DMFT, dmft scores were significantly high among children with autism (2.07 ± 0.83; 0.86 ± 1.22, 1.40 ± 2.48 when compared to children without autism (0.46 ± 0.58; 0.46 ± 1.06, 0.59 ± 1.28 respectively. Out of all domains of OHRQoL, mean score of functional limitations related to teeth problem was significantly higher among children with autism (8.87 ± 5.65 as compared to non-autism group (6.66 ± 4.97. Conclusion: Functional limitations may have a negative impact on oral health status that might influence OHRQoL.

Oral health-related quality of life (OHRQoL) is being increasingly used in epidemiologic studies of dentistry. However, patient-reported OHRQoL does not always coincide with clinical measures. Previous studies have shown a relationship between OHRQoL and personality, but did not concomitantly investigate oral function. We aimed to examine the association among personality traits, oral function, and OHRQoL using a large sample of community-dwelling Japanese elderly. The participants (n = 938; age, 69-71 years) were drawn from a complete enumeration of an urban area and a rural area of both the Tokyo metropolitan area and Hyogo Prefecture. The self-perceived impact of OHRQoL was measured using the Geriatric Oral Health Assessment Index (GOHAI). The oral status and socioeconomic characteristics were recorded in each participant, and personality traits (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) were assessed with the NEO-five-factor inventory. Multiple linear regression analysis was performed to examine the relationships between OHRQoL and other factors, with p Personality traits are associated with OHRQoL independently of objective measures of oral health status in community-dwelling elderly Japanese. This study showed personality traits are associated with OHRQoL independently of dental status and oral function in old Japanese people. As elderly patients undergo increasingly complex dental treatments, there is a need to evaluate patient personality traits prior to dental treatment and predict patient expectations and responses to planned treatment. This is advantageous in determining the most appropriate therapy. Copyright © 2015 Elsevier Ltd. All rights reserved.

Both oral and global health-related quality of life (HRQoL) are markedly impaired in SSc. In this study we aimed to determine the degree of association between oral HRQoL and global HRQoL in SSc. Subjects were recruited from the Canadian Scleroderma Research Group registry. Global HRQoL was measured using the Medical Outcomes Trust 36-item Short Form Health Survey (SF-36) and oral HRQoL with the Oral Health Impact Profile (OHIP). The Medsger Disease Severity Score was used to determine organ involvement. Multivariate regression models determined the independent association of the OHIP with the SF-36 after adjusting for confounders. This study included 156 SSc subjects. The majority (90%) were women, with a mean age of 56 years, mean disease duration 13.8 years (s.d. 8.5) and 29% of the subjects had dcSSc. Mean total OHIP score was 40.8 (s.d. 32.4). Mean SF-36 mental component summary (MCS) score was 49.7 (s.d. 11.1) and physical component summary (PCS) score was 37.0 (s.d. 10.7). In adjusted analyses, the total OHIP score was significantly associated with the SF-36 MCS and PCS, accounting for 9.7% and 5.6% of their respective variances. Measures of disease severity were not related to OHIP score. Oral HRQoL in SSc is independently associated with global HRQoL. Oral HRQoL, however, is not related to physician-assessed disease severity. This suggests that physicians may be disregarding issues related to oral health. HRQoL is an additional dimension of HRQoL not captured by generic instruments such as the SF-36. © The Author 2014.

The present investigation was carried out to understand the impact of formulation and process variables on the quality of oral disintegrating films (ODF) using Quality by Design (QbD) approach. Lamotrigine (LMT) was used as a model drug. Formulation variable was plasticizer to film former ratio and process variables were drying temperature, air flow rate in the drying chamber, drying time and wet coat thickness of the film. A Definitive Screening Design of Experiments (DoE) was used to identify and classify the critical formulation and process variables impacting critical quality attributes (CQA). A total of 14 laboratory-scale DoE formulations were prepared and evaluated for mechanical properties (%elongation at break, yield stress, Young's modulus, folding endurance) and other CQA (dry thickness, disintegration time, dissolution rate, moisture content, moisture uptake, drug assay and drug content uniformity). The main factors affecting mechanical properties were plasticizer to film former ratio and drying temperature. Dissolution rate was found to be sensitive to air flow rate during drying and plasticizer to film former ratio. Data were analyzed for elucidating interactions between different variables, rank ordering the critical materials attributes (CMA) and critical process parameters (CPP), and for providing a predictive model for the process. Results suggested that plasticizer to film former ratio and process controls on drying are critical to manufacture LMT ODF with the desired CQA. Published by Elsevier B.V.

Full Text Available Oral health related quality of life (OHRQoL is a multidimensional concept that measures perceptions of oral health and the consequences of oral conditions at individual and population levels. Poor oral conditions are associated with a deteriorating quality of life (QoL through functional and psychosocial impacts. As the elder population is growing worldwide and the prevalence of oral diseases among older adults remains high, more at- tention needs to be paid to oral health conditions as well as impacts on QoL. However, there are few population studies regarding OHRQoL in older Thai adults. Apparently, there are several challenges facing the assessment and improvement of the OHRQoL of this aging population. First, effort towards the standardization of instruments and validation of translated instruments is needed. Secondly, a multidisciplinary team, composed of health care providers, dental professionals, and policy makers has to be established. Finally, a holistic oral health care concept must be emphasized in dental educational programs and training. This review presents an overview of OHRQoL and its importance to the elderly and discusses future challenges to this group of the population in Thailand.

(i) Quantify the relative association between child dental caries experience and maternal-reported child oral health-related quality of life (OHRQoL); (ii) examine whether that association differed according to family socioeconomic status (SES); and (iii) explore whether absolute OHRQoL varied by family SES at similar levels of child caries experience. This study was a cross-sectional analysis of children in southern Brazil (n=456, mean age: 38 months) participating in an existing health centre-based intervention study. OHRQoL impact was quantified as mean score on the Brazilian Early Childhood Oral Health Impact Scale (ECOHIS) and compared over categories of caries experience (dmft: 0, dmft: 1-4, dmft: ≥5). Adjusted ECOHIS ratios between caries categories were calculated using regression modelling, overall and within socioeconomic strata defined by maternal education, social class and household income. Caries prevalence (dmft >0) was 39.7%, mean ECOHIS score was 2.0 (SD: 3.5), and 44.3% of mothers reported OHRQoL impact (ECOHIS score >0). Increasing child caries experience was associated with worsening child and family quality of life: ECOHIS scores were 3.0 times greater (95% CI: 2.0, 4.4) for children with dmft ≥5 vs dmft=0, a pattern that persisted regardless of family socioeconomic status (P for interaction: all >0.3). However, adjusted for dental status and sociodemographic characteristics, mean ECOHIS scores were lower when reported by mothers of less educational attainment (ratio: 0.7; 95% CI: 0.5, 1.0), lower social class (ratio: 0.7; 95% CI: 0.5, 1.0) or in lower income households (ratio: 0.8; 95% CI: 0.6, 1.3). Dental caries was associated with negative child and family experiences and lower OHRQoL across all social groups; yet, families facing greater disadvantage may report lesser quality-of-life impact at the same level of disease experience. Thus, subjective quality-of-life measures may differ under varying social contexts, with possible
Full Text Available Andrographolide (AND, the diterpene lactone compound, was purified by HPLC from the methanolic fraction of the plant Andrographis paniculata. The compound was found to have potent antiplasmodial activity when tested in isolation and in combination with curcumin and artesunate against the erythrocytic stages of Plasmodium falciparum in vitro and Plasmodium berghei ANKA in vivo. IC50s for artesunate (AS, andrographolide (AND, and curcumin (CUR were found to be 0.05, 9.1 and 17.4 μM, respectively. The compound (AND was found synergistic with curcumin (CUR and addictively interactive with artesunate (AS. In vivo, andrographolide-curcumin exhibited better antimalarial activity, not only by reducing parasitemia (29%, compared to the control (81%, but also by extending the life span by 2-3 folds. Being nontoxic to the in vivo system this agent can be used as template molecule for designing new derivatives with improved antimalarial properties.

Few research studies have examined longitudinal improvements in oral communication skills and quality of peer relationships of children with implants. Moreover, although the emerging literature suggests that improvement in social functioning follows improvement in oral communication, it is still unknown what factors enhance or impede the relations between these constructs. Based on parent interviews, the current study examined the long-term improvements in speech and oral language skills and relationships with hearing peers in 19 implanted children. Results demonstrate that on average, children continue to improve in oral communication skills and quality of peer relationships even years after implantation, especially those with initial poorer skills. While oral communication ability and quality of peer relationships are strongly associated at each time point, gains in these two variables are associated only for some of the children. Other factors, including self-confidence and peer acceptance, seem to moderate this relationship. Qualitative data are presented to illustrate these relations among variables and to assist in theory building. The results highlight the need for more specific examination of various developmental periods in combination with the progress of oral communication and peer relationships among children with implants. © 2013 John Wiley & Sons Ltd.

To categorise the content and assess the quality and readability of the online information regarding the treatment for oral leukoplakia. An online search using the term 'leukoplakia treatment' was carried out on 8th June 2015 using the Google search engine. The content, quality and readability of the first 100 sites were explored. The quality of the web information was assessed using the following tools, the DISCERN instrument and the Journal of the American Medical Association (JAMA) benchmarks for website analysis and the HON seal. Readability was assessed via the Flesch Reading Ease Score. The search strategy generated 357 000 sites on the Google search engine. Due to duplicate links, non-operating links and irrelevant links, a total of 47 of the first 100 websites were included in this study. The mean overall rating achieved by included websites using the DISCERN instrument was 2.3. With regard to the JAMA benchmarks, the vast majority of examined websites (95.7%) completely fulfilled the disclosure benchmark and less than 50% of included websites met the three remaining criteria. A mean total readability score of 47.5 was recorded with almost 90% of websites having a readability level ranging from fairly difficult to very difficult. Based on this study, the online health information regarding oral leukoplakia has challenging readability with content of questionable accuracy. As patients often search for health information online, it would be prudent for clinicians to highlight the caution with which online information should be interpreted. © 2016 John Wiley & Sons A/S.

Full Text Available Abstract Background The goal of this study was to evaluate the somatic and psychological effects by means of QUALITY OF LIFE (QOL of surgical treatment of patients with oral squamous cell carcinoma. The factors gender, age, nicotine consumption, and tumour stage were taken into consideration. Methods 54 patients after surgical resection of oral squamous cell carcinomas (OSCC were analysed from 01.09.2005 to 31.05.2008. Inclusion criteria for the study were: age at least 18 years, no indication or treatment of synchronous and metachronous tumours. German translations of the EORTC H&N-35 and EORTC QLQ-C-30 questionnaires, as well as a general socioeconomic patient history were used as measuring instruments. The questionnaires were completed independently by the patients. The answers were translated into scale values for statistical evaluation using appropriate algorithms. Results Analysis of the EORTC-QLQ-C-30 questionnaires demonstrated a tendency of more negative assessment of emotional function among the female participants, and a more negative evaluation of social function among the male participants. Greater tumour sizes showed significantly lower bodily function (p = 0.018. While a smaller tumour size was significantly associated with lower cognitive functioning (p = 0.031. Other cofactors such as age, nicotine consumption, and tumour stage only showed a tendency to influence the quality of sleep and daily life. Conclusions The data obtained within this investigation demonstrated that gender had the most significant power on the subjectively perceived postoperative quality of life. This factor is important e.g. in preoperative decision making regarding immediate microvascular reconstruction after e.g. mandibular resection and therefore QOL assessment should become integral component of the care of patients with OSCC.

Severe malaria is a medical emergency associated with high mortality. Adequate treatment requires initial parenteral therapy for fast parasite clearance followed by longer acting oral antimalarial drugs for cure and prevention of recrudescence. In a randomized controlled clinical trial, we evaluated the 42-day parasitological outcomes of severe malaria treatment with intravenous artesunate (AS) or intravenous quinine (QNN) followed by oral artemisinin based combination therapy (ACT) in children living in a high malaria transmission setting in Eastern Uganda. We enrolled 300 participants and all were included in the intention to treat analysis. Baseline characteristics were similar across treatment arms. The median and interquartile range for number of days from baseline to parasite clearance was significantly lower among participants who received intravenous AS (2 (1-2) vs 3 (2-3), P malaria symptoms. In this high transmission setting, we observed adequate initial treatment outcomes followed by very high rates of malaria re-infection post severe malaria treatment. The impact of recurrent antimalarial treatment on the long term efficacy of antimalarial regimens needs to be investigated and surveillance mechanisms for resistance markers established since recurrent malaria infections are likely to be exposed to sub-therapeutic drug concentrations. More strategies for prevention of recurrent malaria infections in the most at risk populations are needed. The study was registered with the Pan African Clinical Trial Registry ( PACTR201110000321348 ).

Full Text Available Abstract This study evaluated the impact of molar–incisor hypomineralization (MIH on oral health-related quality of life (OHRQoL according to the perceptions of schoolchildren and their parents/caregivers. This cross-sectional study consisted of a sample of 594 schoolchildren between 11 and 14 years of age and their parents/caregivers who answered the questionnaires CPQ11–14ISF:16 and P-CPQ, respectively. The main independent variable of this study was MIH of the schoolchildren. Experience of dental caries, malocclusion, and socioeconomic status were treated as confounding variables. Statistical analysis used descriptive analysis and Poisson regression with robust variance. The prevalence of MIH was 18.9%. The overall P-CPQ score ranged from 0 to 35 (average = 7.26 ± 6.84, and the overall CPQ11-14ISF:16 score ranged from 0 to 47 (average = 11.92 ± 7.98. Severe MIH was associated with a greater negative impact of the “functional limitation” domain (RR = 1.41; 95%CI = 1.01–1.97, according to parents’/caregivers’ perceptions. Severe MIH was associated with a greater negative impact of the “oral symptom” domain (RR = 1.30; 95%CI = 1.06–1.60 and functional limitation domain (RR = 1.42; 95%CI = 1.08–1.86, according to the schoolchildren’s perceptions. Schoolchildren with severe MIH had a greater negative impact on the oral symptom and functional limitation domains than those without MIH. According to parents’/caregivers’ perceptions, schoolchildren with severe MIH had a greater negative impact on the functional limitation domain than those without MIH.

To clarify the relationship between masticatory performance and oral health-related quality of life (OHRQoL) before and after complete denture treatment. Thirty patients wearing complete dentures were asked to chew a gummy jelly on their habitual chewing side, and the amount of glucose extraction during chewing was measured as the parameter of masticatory performance. Subjects were asked to answer the Oral Health Impact Profile (OHIP-J49) questionnaire, which consists of 49 questions related to oral problems. The total score of 49 question items along with individual domain scores within the seven domains (functional limitation, pain, psychological discomfort, physical disability, psychological disability, social disability and handicap) were calculated and used as the parameters of OHRQoL. These records were obtained before treatment and 3 months after treatment. Each parameter of masticatory performance and OHRQoL was compared before treatment and after treatment. The relationship between masticatory performance and OHRQoL was investigated, and a stepwise multiple linear regression analysis was performed. Both masticatory performance and OHRQoL were significantly improved after treatment. Furthermore, masticatory performance was significantly correlated with some parameters of OHRQoL. The stepwise multiple linear regression analysis showed functional limitation and pain as important factors affecting masticatory performance before treatment and functional limitation as important factors affecting masticatory performance after treatment. These results suggested that masticatory performance and OHRQoL are significantly improved after treatment and that there is a close relationship between the two. Moreover, functional limitation was found to be the most important factor affecting masticatory performance. Copyright © 2018 Japan Prosthodontic Society. Published by Elsevier Ltd.

The aim of the study was to evaluate parental influence on children's answers to an oral health-related quality of life (OHRQoL) questionnaire. A cross-sectional study was conducted with a non-probabilistic sample of 84 pairs of 5-year-olds and parents/guardians. The participants were selected from a primary family healthcare center in Campina Grande, Brazil. First, the children and parents answered respective versions of the Scale of Oral Health Outcomes for Five-Year-Old Children (SOHO-5). Seven days later, the children answered their version of the SOHO-5, without the presence of their parents/guardians, and underwent a clinical exam of dental caries, traumatic dental injury and malocclusion, by a previously calibrated researcher. Statistical analysis involved a comparison of mean scores and the calculation of the intraclass correlation coefficient (ICC). Poisson regression models were used to associate the variables (α = 5%). No significant differences were found between the mean SOHO-5 scores of the children when alone or accompanied by parents/guardians (p > 0.05). The ICC between the answers of the children alone or accompanied was 0.84. White spot (PR = 6.32; 95%CI: 1.36 - 29.40) and cavitated lesions (PR = 9.81; 95%CI: 3.22 - 29.85) had an impact on OHRQoL, according to the children's self-report, whereas cavitated lesions (PR = 90.52; 95%CI: 13.26 - 617.74) and anterior open bite (PR = 1.95; 95%IC: 1.07 - 3.53) remained on the final model, according to the parents' version of the SOHO-5. In conclusion, parents did not influence the children's responses, and dental caries are the oral health problem exerting the greatest impact on the children's OHRQoL.

Severe malaria remains a major cause of mortality and morbidity for children living in many tropical regions. With the emergence of strains of Plasmodium falciparum resistant to both chloroquine and quinine, alternative antimalarial agents are required. The artemisinin group of compounds are rapidly effective in severe disease when given by intramuscular or intravenous injection. However, these routes of administration are not always available in rural areas. In an open, randomized comparison 109 Vietnamese children, aged between 3 months and 14 years, with severe P.falciparum malaria, were allocated at random to receive artemisinin suppositories followed by mefloquine (n = 37), intramuscular artesunate followed by mefloquine (n = 37), or intravenous quinine followed by pyrimethamine/sulfadoxine (n = 35). There were 9 deaths: 2 artemisinin, 4 artesunate and 5 quinine-treated children. There was no difference in fever clearance time, coma recovery, or length of hospital stay among the 3 groups. However, parasite clearance times were significantly faster in artemisinin and artesunate-treated patients than in those who received quinine (P children receiving these drugs had lower peripheral reticulocyte counts by day 5 of treatment than those in the quinine group (P = 0.011). No other adverse effect or toxicity was found. There was no treatment failure in these 2 groups, but 4 patients in the quinine group failed to clear their parasites within 7 d of starting treatment and required alternative antimalarial therapy. Artemisinin suppositories are easy to administer, cheap, and very effective for treating children with severe malaria. In rural areas where medical facilities are lacking these drugs will allow antimalarial therapy to be instituted earlier in the course of the disease and may therefore save lives.

The study aimed to compare the oral health variables, general, and oral health-related quality of life (QoL), depression, and anxiety between spinal cord injury (SCI) patients and healthy controls and also to determine the key factors related to the oral health-related quality of life (OHRQoL) in the SCI patients. A total of 203 SCI patients and 203 healthy controls were enrolled. Patients and healthy adults were invited to attend a dental clinic to complete the study measures and undergo oral clinical examinations. OHRQoL was assessed by the 14-item Oral Health Impact Profile (OHIP-14), and the general health-related quality of life (GHRQoL) was evaluated by SF-36. In SCI patients, depression and anxiety were recorded using the Hospital Anxiety and Depression Scale (HADS), while Functional Assessment Measure (FAM) was used to assess dependence and disability. All the subjects were examined for caries which was quantified using the decayed, missing, and filled Teeth (DMFT) index, gingival bleeding index (GI), plaque index, and periodontal status by community periodontal index (CPI). The analysis of covariance (ANCOVA) revealed significant differences between the two groups in terms of oral health expressed in DMFT, oral hygiene, and periodontal status, controlled for age, gender, family income, and occupational status (poral hygiene practices, greater levels of plaque, gingival bleeding, and caries experience than the healthy controls. In addition, more number of SCI patients had periodontal pockets and dry mouth than the comparative group. SCI patients experienced more depression and anxiety, poor GHRQoL, and OHRQoL than the healthy control group. The factors that influenced OHRQoL in SCI patients were age, toothbrushing frequency, smoking, oral clinical status, depression, physical component of GHRQoL, and level of lesion.

To determine xerostomia-related frequency, factors, salivary flow rates and Oral Health-Related Quality of Life (OHRQoL) of patients attending the Universidad Andrés Bello Dental School Clinic, in the city of Viña del Mar, Chile. The study involved 566 patients assessed with xerostomia, based on a single standardized questionnaire. The severity and impact of xerostomia on OHRQoL was assessed using a visual analogue scale (VAS) and the short version of the Oral Health Impact Profile Questionnaire (OHIP-14sp), respectively. Stimulated and non-stimulated salivary flow rates were obtained from a sample of patients. Xerostomia was reported in 61 patients (10.8%), comprising 50 women (83.3%) and 11 men (16.7%) (p xerostomia. Hyposalivation was found in 10 of the 35 patients with xerostomia (28.6%) and in 2 patients without it (p xerostomia had a reduced OHRQoL, compared with patients without xerostomia, as shown by the total OHIP-14sp score (p Xerostomia was a common, potentially debilitating condition with a major impact on the OHRQoL of a patient population attending a university-based dental clinic. Hyposalivation was present in almost 30% of the patients who complained of xerostomia. It is important that general dentists be aware of this condition, so that they can provide patients with a good diagnosis, treatment and follow-up.

Objectives: To evaluate masticatory efficiency (ME) and oral health-related quality of life (OHRQoL) in patients rehabilitated with implant-retained mandibular overdentures. Methods: In this randomized controlled clinical trial, 50 edentulous patients visiting the Implant Center and Department of Prosthodontics, West China College of Stomatology, Sichuan University, Chengdu, China between June 2010 and June 2012 were selected and received 2 implant-retained mandibular overdenture treatments. All patients were rehabilitated with maxillary complete dentures. The ME and OHRQoL were determined both one month before the mandibular complete denture was anchored to the osseointegrated implants, and 6 months after anchoring. Paired t-tests were used to compare means of ME, and oral health impact profile-49 (OHIP-49) domains scores between pre- and post-implant. Linear regression models were utilized to seek correlations between ME and OHIP domains scores. Results: The ME increased from pre- to post-implant retained mandibular overdentures significantly (p<0.001). The total OHIP score and 4 subscales scores were changed significantly from pre- to post-implant; namely, functional limitation, psychological discomfort, physical disability, and physical pain. The total OHIP score, functional limitation, physical disability, and physical pain subscale scores were related to ME. Conclusion: Implant-retained mandibular over dentures can significantly improve patients’ ME and OHRQoL. The improvement in OHRQoL is mainly because of the improved ME. An improved chewing experience, and pain relief also contributes to improvement of OHRQoL. PMID:25316463

The aim of this study was to investigate associations between objectively and subjectively measured masticatory function and oral health-related quality of life (OHRQoL) in partial maxillectomy patients wearing dentomaxillary prostheses. A sample of 32 consecutively treated patients who had undergone a partial maxillectomy were enrolled. Masticatory function was assessed using two objective measures and one subjective measure. The objective measures were masticatory performance (MP), which was estimated by measuring the glucose extracted from gummy jelly, and food mixing ability (a*), which was assessed using color-changeable chewing gum. The subjective measure was perceived chewing ability, rated as masticatory score (MS) based on the patient's responses to a food intake questionnaire. OHRQoL was assessed using the Geriatric Oral Health Assessment Index (GOHAI). Relationships between the masticatory function measures and OHRQoL were analyzed using Spearman rank correlation coefficient. The correlation coefficients (r) obtained were 0.57 (P = .001) for MS and GOHAI, 0.247 (P = .173) for MP and GOHAI, -0.173 (P = .343) for a* and GOHAI, 0.517 (P = .002) for MP and a*, 0.199 (P = .257) for MP and MS, and 0.019 (P = .919) for a* and MS. Subjective MS showed a significant positive correlation with GOHAI score, suggesting that perceived chewing ability could be an important factor in the estimation of OHRQoL in partial maxillectomy patients.

To evaluate the direct and indirect (via oral health-related behaviour) effects of parental rearing practices on children's Oral Health-Related Quality of Life (OHRQoL) within a family-focused, comprehensive predictive model. Participants were 11- to 14-year-old children and their parents living in Telangana State, India (N = 1130). Children were clinically assessed for dental caries, gingivitis, oral hygiene status, fluorosis, and malocclusion, and completed a self-administered questionnaire on oral health-related behaviour and OHRQoL. Parents answered questions related to their socioeconomic status (SES), family circumstances, parent's perceptions of child's OHRQoL, and child rearing practices. Structural equation modelling was used to evaluate the pathways through which parenting practices were associated with children's OHRQoL. Parents with higher positive (β = -0.106) and lower power assertion rearing practices (β = 0.103) had children with better OHRQoL. Parental rearing practices did not have any effect on children's oral hygiene behaviour. Children who had malocclusion (β = 0.076) and fluorosis (β = 0.38) had lower OHRQoL. Family SES had a significant effect on children's oral hygiene behaviour and oral hygiene status with children of higher SES demonstrating better oral hygiene behaviour and status. Children living in single-parent families reported poorer oral hygiene behaviour (β = -0.048) than those living in other types of families. Parental rearing practices had direct effects on OHRQoL. However, the hypothesised indirect effects of these practices on OHRQoL via poor oral health behaviour were not supported.

This study aimed to assess childhood bruxism relating associated factors and the bruxism's impact on oral health-related quality of life (OHRQoL). A case-control study was performed with 3- to 6-year-old children obtained from public preschools in Brazil. The case and control groups had 21 and 40 children, respectively. Associations between bruxism and respiratory problems (p = 0.04, OR: 0.33, CI: 0.09 to 1.14), dental wear (p 0.05). The association between presence and absence of impact with bruxism or other variables showed no statistical relationship (p > 0.05). It could be concluded that childhood bruxism is related to respiratory problems, dental wear, dental caries, and malocclusion. Despite being a topic that demands special care in dentistry, bruxism does not significantly affect the OHRQoL. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

In the world of diagnostic imaging, radiography is an important supplementary method for dental diagnosis. In radiology, special attention must be paid to the radiological protection of patients and health professionals, and also to image quality for correct diagnosis. In Brazil, the national rules governing the operation of medical and dental radiology were specified in 1998 by the National Sanitary Surveillance Agency, complemented in 2005 by the guide "Medical radiology: security and performance of equipment." In this study, quality control tests were performed in public clinics with dental X-ray equipment in the State of Sergipe, Brazil, with consideration of the physical parameters that influence radiological protection and also the quality of images taken in intra-oral radiography. The accuracy of the exposure time was considered acceptable for equipment with digital timers. Exposure times and focal-spot size variations can lead to increased entrance dose. Increased dose has also been associated with visual processing of radiographic film, which often requires repeating the radiographic examination.

Full Text Available Background: Implant-prosthodontic rehabilitation improves oral health related quality of life (OHRQoL, but the presence of systemic diseases can also affect the well-being of an individual.The study was carried out to determine the relationship between systemic diseases and OHRQoL after implant-prosthodontic rehabilitation on the basis of psychometric testing by a standardized questionnaire »Oral Health Impact Profile« (OHIP.Methods: 130 patients, who received one to eight Ankylos® implants (on average 2.6 ± 1.8 were included in this retrospective study in which all aspects of the OHRQoL construct were evaluated with a Slovenian version of the OHIP questionnaire. Data on all present systemic diseases were obtained from the existing health records. Dental status and dental restorations were identified on the basis of orthopantomographic images.Results: The majority of subjects had a cardiovascular disease (N = 37; 28.5 %, followed by a headache (N = 15, 11.5 %, allergies and asthma (n = 13, 10 %, and a rheumatic disease (N = 11, 8.5 %. Only osteoporosis was statistically significantly related to OHRQoL after implant-prosthodontic rehabilitation (p = 0.024. The best multiple linear regression model for the summary score for the questionnaire »Oral Health Impact Profile« for Slovenia (OHIP, and taking into account gender and age as confounding factors, included the number of remaining teeth and the presence of osteoporosis (p = 0.003, adjusted R2 = 0.104.Conclusions: The total number of remaining teeth in the oral cavity (p = 0.031, the presence of osteoporosis (p = 0.024, and taking into account the subject’s gender and age, are the most important clinical factors that affect the functioning of the SGS as well as psychosocial behavior of the patients after an implant-prosthodontic rehabilitation (adjusted R2 = 0.104.

Full Text Available Aim: The aim of the study is to assess the impact of oral health related quality of life (QOL on patients presenting for scaling and oral prophylaxis using a the oral health-related quality of life (OHRQL questionnaire. Materials and Methods: This prospective study includes a total of 100 male patients of age group 25-35 years, who visited private clinic in Namakkal district, South India. They were assessed for their perceptions of oral health using OHRQL questionnaire before initial periodontal therapy including scaling and root planning. Results: A total of 100 patients (mean age:29 years participated in the study and completed initial periodontal therapy. Before treatment 98% of the patients perceived that their oral health status impacted on their QOL in one or more ways. Bad breath was the most common complaint. Social well-being, personality and psychological function were identified as compromised OHRQL domains. More than 60% of the patients stated their overall general health is affected by periodontal disease. Conclusion: Periodontitis negatively affected QOL in this Namakkal district population of young male patients with mild periodontitis. Conventional non-surgical periodontal therapy and personality development counseling has a potential to ameliorate patient perceptions of oral health and improve their QOL.

The existing body of evidence reports an inconsistent association between subjective and objective orthodontic treatment need. The concept of oral health-related quality of life (OHRQoL) might help to explain the differences in subjective and objective orthodontic treatment need. Our aim was to investigate the association of subjective orthodontic treatment with OHRQoL in children. This cross-sectional study was embedded in the Generation R Study, a population-based prospective cohort study. OHRQoL and subjective orthodontic treatment need were assessed by parental questionnaires. Questionnaire items were individually compared among children with no, borderline and definite subjective orthodontic need. The association between subjective orthodontic treatment need and OHRQoL was investigated in multivariate regression analysis with weighted least squares. Differences by sex and levels of objective orthodontic treatment need were evaluated. In total, 3774 children were included in the analysis. Children with borderline subjective orthodontic treatment need and those with definite subjective orthodontic treatment need had significantly poorer OHRQoL based on the fully adjusted model (adjusted regression coefficient (aβ)=-0.49, 95% CI: -0.75, -0.30; (aβ)=-1.58, 95% CI: -1.81, -1.58, respectively). The association between subjective orthodontic treatment need and OHRQoL was stronger in girls than in boys and stronger in children with objective orthodontic treatment need than in those with none. Oral health-related quality of life is poorer in children with subjective orthodontic treatment need. This has not been investigated before in such a large-population-based study and clearly offers an explanation for the lack of concurrence between objective and subjective orthodontic treatment need. © 2017 John Wiley & Sons A/S.

Purpose: To investigate the changes in salivary function and oral health-related quality of life for patients with nasopharyngeal carcinoma treated by intensity-modulated radiotherapy (IMRT). Methods and Materials: A total of 57 patients with early-stage nasopharyngeal carcinoma received IMRT. The parotid and whole saliva flow was measured, and the Medical Outcomes Study 36-item short form, European Organization for Research and Treatment of Cancer Quality of Life questionnaire-C30, European Organization for Research and Treatment of Cancer Quality of Life questionnaire 35-item head-and-neck module, and Oral Health Impact Profile questionnaires were completed at baseline and 2, 6, 12, 18, and 24 months after IMRT. Results: Parotid saliva flow recovered fully after 1 year and maintained. Whole saliva flow recovered partially to 40% of baseline. A general trend of deterioration in most quality of life scales was observed after IMRT, followed by gradual recovery. Persistent oral-related symptoms were found 2 years after treatment. Conclusion: IMRT for early-stage nasopharyngeal carcinoma could only partially preserve the whole salivary function and oral health-related quality of life.

WHO recommends artemisinin suppository formulations as pre-referral treatment for children who are unable to take oral medication and cannot rapidly reach a facility for parenteral treatment. We investigated factors influencing caretakers' adherence to referral advice following pre-referral treatment of their children with rectal artesunate suppositories. The study was nested within an intervention study that involved pre-referral treatment of all children who came to a community dispenser for treatment because they were unable to take oral medications because of repeated vomiting, lethargy, convulsions or altered consciousness. All patients who did not comply with referral advice were stratified by actions taken post-referral: taking their children to a drug shop, a traditional healer, or not seeking further treatment, and added to a random selection of patients who complied with referral advice. Caretakers of the children were interviewed about their socio-economic status (SES), knowledge about malaria, referral advice given and actions they took following pre-referral treatment. Interview data for 587 caretakers were matched with symptoms of the children, the time of treatment, arrival at a health facility or other actions taken post-pre-referral treatment. The majority (93.5%) of caretakers reported being given referral advice by the community drug dispenser. The odds of adherence with this advice were three times greater for children with altered consciousness and/or convulsions than for children with other symptoms [odds ratio (OR) 3.47, 95% confidence interval (CI) 2.32-5.17, P < 0.001]. When questioned, caretakers who remembered when (OR 2.19, 95% CI 1.48-3.23, P < 0.001) and why (OR 1.77, 95% CI 1.07-2.95, P = 0.026) they were advised to proceed to health facility - were more likely to follow referral advice. Cost did not influence adherence except within a catchment area of facilities that charged for services. In these areas, costs deterred adherence by

Full Text Available Background: Children′s oral health related quality of life (OHRQoL evaluates the impacts of oral daily activities of children and family on quality of life. Oral health related quality of life as outcome can be used to evaluate the dental health services. This study aimed to assess the extent to which den-tal treatment under general anesthesia affects quality of life of children and their families. Methods: One hundred parents of 3-10 year-old children who needed dental treatment under general anesthesia completed a parent-children perception questionnaire (P-CPQ and family impact scale (FIS before, and 4 weeks after dental treatment under general anesthesia. The questionnaire had statements related to oral health, functional limitation, emotional state and well being social well-being and family issues. Data were analyzed using SPSS version 11.5. Results: The mean scores and standard deviations of oral health quality of life of the children before and after dental treatment were 43.3 ± 7.14 and 39.24 ± 5.47 respectively. The mean scores of FIS before and after dental treatment were 8.00 ± 3.21 and 3.66 ± 2.62, respectively. The effect size of mean differences in P-CPQ and FIS scores were 1.84 ± 1.64 and 1.35 ± 4.34, respectively. Conclusion: Provision of dental treatment under general anesthesia for uncooperative, young chil-dren with extensive dental problems had significant effects on quality of life of both children and their families.

Artemisinin- and artesunate-resistant Plasmodium chabaudi mutants, AS-ART and AS-ATN, were previously selected from chloroquine-resistant clones AS-30CQ and AS-15CQ respectively. Now, a genetic cross between AS-ART and the artemisinin-sensitive clone AJ has been analysed by Linkage Group Selection. A genetic linkage group on chromosome 2 was selected under artemisinin treatment. Within this locus, we identified two different mutations in a gene encoding a deubiquitinating enzyme. A distinct mutation occurred in each of the clones AS-30CQ and AS-ATN, relative to their respective progenitors in the AS lineage. The mutations occurred independently in different clones under drug selection with chloroquine (high concentration) or artesunate. Each mutation maps to a critical residue in a homologous human deubiquitinating protein structure. Although one mutation could theoretically account for the resistance of AS-ATN to artemisinin derivates, the other cannot account solely for the resistance of AS-ART, relative to the responses of its sensitive progenitor AS-30CQ. Two lines of Plasmodium falciparum with decreased susceptibility to artemisinin were also selected. Their drug-response phenotype was not genetically stable. No mutations in the UBP-1 gene encoding the P. falciparum orthologue of the deubiquitinating enzyme were observed. The possible significance of these mutations in parasite responses to chloroquine or artemisinin is discussed.

Objective: To investigate the effect of Artesunate combining with radiation on apoptosis in transplanted tumors. Methods: HeLa cells were inoculated into the nude mice to develop a tumor model. Mice were randomized into four groups as the control group, the Artesunate group,the irradiation group and the combination group when average volume of tumor achieved about 5 mm x 5 mm x 5 mm. During the period of treatment, the volume of tumors was measured per 2 days. After 14 days treatment, the mice were killed and tumor tissues were harvest, the tumor size and weight were measured, tumor inhibitory rate calculated and TUNEL assay was used to analysis the apoptosis of tumor tissue. Results: The tumor weight in combination group was significantly lower than that than in the irradiation group [(0.64 ± 0.11) gvs (1.31 ± 0.58) g] (P<0.05), the tumor inhibitory rate was 71.17%. The apoptosis in the combination group was obviously higher than that in the irradiation group [(77.5 ± 8.07) %vs (48.80 ± 6.71) %] (P<0.05 ). Conclusion: Artesunate can dramatically increase the radiosensitivity of tumor model transplanted with HeLa cells of cervical cancer, the possible mechanism of radiosensitization of Artesunate is related to increasing apoptosis of tumor cells.

Full Text Available Background/Aim. The Oral Impacts on Daily Performance (OIDP is a well-known psychometric test used internationally to assess the oral health-related quality of life. The interview and self-administrated questionnaire both assess the degree to which oral health problems have affected the life of the participants over the previous 6 months. The aim of this study was to translate the OIDP index into Serbian and to assess its reliability in practice as its initial verification in the Serbian speaking area. Methods. Following an internationally established methods, the OIDP scale was translated using standardized methodology that consisted of forward translation, pilot study and backward translation. Results. A pilot study was carried out with 44 respondents (24 males i 20 females using a preliminar Serbian version of the OIDP index. All patients were aged over 65 years. A total of 68.2% of the participants replied that they had at least one OIDP impact on daily life in the past 6 months. These troubles were most prominent during eating (47.7% and speaking (36.4%, but there is a little impact of troubles in the domain of psychosocial sphere. The corrected item-total correlation coefficients for all items were above the minimum recommended level of 0.20 for including an item in a scale. The standardized Cronbach’s alpha coefficient was 0.75. Conclusion. Based on these results, we can conclude that this index is suitable for use in everyday practice in Serbian speaking area providing useful information required to assess oral health-related quality of life.

Purpose: To compare image quality in magnetic resonance cholangiopancreatography (MRCP) performed with and without oral application of Loesferron trademark (ferrous gluconate, Lilly Pharma, Hamburg). Materials and Methods: A prospective study compares MRCPs performed on 52 patients with a 1.5 T clinical whole body scanner using a standard body coil. After randomization, patients ingested either 0.5 l of Loeseferron trademark (n=27, group 1) or no oral contrast agent (n=25, group 2) prior to the examination. 7 RARE (40 to 20 ) sequences were obtained, followed by selected 3 mm HASTE (T 2 -weighted with fat suppression) sequences. After blinding, image quality was rated by two radiologists using a scale of 1 (not discernible) to 5 (very well discernible). The following sections of the biliary ductal system were evaluated: left and right hepatic duct, extrahepatic bile duct and intrapancreatic bile duct. The pancreatic duct was evaluated by its location: head, body and tail of the pancreas. A Wilcoxon-Mann-Whitney test was used to determine significant differences (p trademark was well tolerated by all patients, and all sequences could be acquired and evaluated in all 52 patients. For the different sections of the biliary system, the mean ratings with and without Loesferron trademark were, respectively, 3.28 and 3.36 for the left hepatic duct, 3.26 and 3.33 for the right hepatic duct, 3.46 and 4.0 for the extrahepatic bile duct, and 2.8 and 3.48 for the intrapancreatic bile duct. The corresponding ratings for the pancreatic duct were 2.8 and 3.24 for the pancreatic head, 2.84 and 3.38 for the pancreatic body, and 2.68 and 3.22 for the pancreatic tail. The differences with and without contrast agent were not statistically significant. Interobserver variability was between 0.37 for the pancreatic duct in the tail of the pancreas and 0.66 for the right hepatic duct. Conclusion: Despite the trend toward a better rating of the image quality for all sections of the

Prosthodontic treatment has a positive effect on oral health-related quality of life (OHRQoL); however, there is a paucity of studies assessing the impact of OHRQoL based on where in the mouth ("location") the treatment is performed. This exploratory study investigated the association of the location (anterior, posterior region) of prosthodontic treatment with magnitude and nature of OHRQoL changes. In this non-randomized prospective clinical study, 190 adult patients (17-83 years) were recruited at baseline and 104 were available for the follow-up analyses. Of those, 50 patients received treatment only in the posterior segment and 54 patients in both anterior and posterior regions. Treatment included conventional fixed partial prostheses, removable prostheses or a combination of both. OHRQoL was assessed with the German language version of the 49-item Oral Health Impact Profile (OHIP) at baseline and the questionnaire was repeated 4-6 weeks post-treatment. Magnitude and effect size of changes in summary and sub-scale scores were calculated and data analyzed. Patients experienced a substantially impaired OHRQoL (mean OHIP score: 32.3 points) at baseline and an improvement in OHRQoL of 6.8 OHIP points following treatment. This study showed a greater improvement in OHRQoL in patients treated in both regions compared to those treated in the posterior region alone, especially in the function and aesthetic domains. This explorative study suggests that OHRQoL improvement is affected by where prosthodontic treatment is performed in the mouth. Greater understanding of qualitative aspects of reconstructive therapies is needed for improved treatment planning and patient consent. Copyright © 2014 Japan Prosthodontic Society.

The impact of enamel defects of the first permanent molars on caries experience and child oral health-related quality of life was evaluated in a cohort study. Children who participated in a study of enamel defects of the first permanent molars 8 years earlier were invited for a follow-up assessment. Consenting children completed the Child Perception Questionnaire and the faces Modified Child Dental Anxiety Scale, and were examined by two calibrated examiners. ANOVA, Kruskal-Wallis, negative binomial and logistic regression were used for data analyses. One hundred and eleven children returned a completed questionnaire and 91 were clinically examined. Negative binomial regression found that oral health impacts were associated with gender (boys, risk ratio (RR) = 0.73, P = 0.03) and decayed, missing or filled permanent teeth (DMFT) (RR = 1.1, P = 0.04). The mean DMFT of children were sound (0.9, standard deviation (SD) = 1.4), diffuse defects (0.8, SD = 1.7), demarcated defects (1.5, SD = 1.4) and pit defects (1.3, SD = 2.3) (Kruskal-Wallis, P = 0.05). Logistic regression of first permanent molar caries found higher odds of caries experience with baseline primary tooth caries experience (odds ratio (OR) = 1.5, P = 0.01), the number of teeth affected by enamel defects (OR = 1.9, P = 0.05) and lower odds with the presence of diffuse enamel defects (OR = 0.1, P = 0.04). The presence of diffuse enamel defects was associated with lower odds of caries experience. © 2016 Australian Dental Association.

This study compared scores and psychometric properties from self-identified Hispanic parents who completed Pediatric Oral Health-related Quality of life (POQL) parent report-on-child questionnaires in Spanish or English. The study hypothesized that there were no differences in psychometric properties or POQL scores by parent reading language preference, controlling for dental needs, child's place of birth, age, insurance and use of care. POQL scores were computed, and the internal consistency, feasibility, factor structure and construct validity of the Spanish language version assessed. Hispanic parents (N = 387) of 8-14 year old children (mean age 10.2) completed the survey; 237 in Spanish and 150 in English. Internal consistency scores were higher (Cronbach α range = .86-.93) among Hispanic parents who completed the questionnaire in Spanish than in English (.66-.86). POQL scores from parents who completed questionnaires in Spanish were higher (worse) overall (6.03 vs. 3.82, P = 0.022), as were physical (11.61 vs. 6.54, P = 0.001) and role functioning domains (1.87 vs. 0.82, P = 0.029). Items for crying, pain, and eating were higher (P parent reports of dental visit in the last year (P = 0.05) and worse oral health than a year ago (P = 0.002), controlling for reading language (not significant) and visit in last year in the final multivariate linear regression. © 2013 American Association of Public Health Dentistry.

Child oral health-related quality of life (COHRQoL) has been increasingly assessed. However, the full relationship between gingivitis and COHRQoL has been assessed by only a small number of studies. This study aims to assess the association between gingival bleeding and how a child perceives its OHRQoL. This cross-sectional study used multistage random sampling to enroll 1,134 12-year-old schoolchildren from Santa Maria, a southern city in Brazil. Participants were examined for gingival bleeding according to the community periodontal index criteria, a full-mouth clinical examination of six sites per tooth. COHRQoL was assessed by the Brazilian version of the Child Perceptions Questionnaire for 11- to 14-Year-Old Children (CPQ11-14), and data on socioeconomic status were collected. Multilevel Poisson regression models fitted the association of gingivitis with overall and domain-specific CPQ11-14 scores. In general, children with bleeding in ≥15% of sites had higher total CPQ11-14 scores and domain-specific scores than their counterparts. This association persisted after adjustment for other potential confounders. The presence and extent of gingival bleeding was associated mainly with emotional limitation domains of the CPQ11-14; those with extended levels of gingivitis had a 1.20 times higher mean score than those with low-level/no gingival bleeding (rate ratio = 1.20; 95% confidence interval = 1.10 to 1.31). The present results indicate that the presence of extensive levels of gingivitis might be negatively associated with how children perceive their oral health and their daily life.

The aim of this study was to investigate if and how the personality traits Negative Affectivity (NA) and self-esteem influenced the Oral Health Related Quality of Life (OHRQoL) in patients receiving oral rehabilitation. OHRQoL was measured by the Oral Health Impact Profile 49 (OHIP-49), NA with a short form of the Eysenck Personality Inventory Questionnaire (EPI-Q), and self-esteem with Rosenbergs Self-Esteem Scale (RSES) in 66 patients treated with removable dental prosthesis (RDP). The minimally important difference (MID), effect size (ES), and standard error of the measurement (SEM) were used to clinically interpret the patient-reported effect. The OHIP-49 score was significantly higher and exceeded the MID pre- and post-treatment in participants with high EPI-Q and low RSES score compared to participants with low EPI-Q and high RSES score. The improvement in OHIP-49 score was significant and not limited by high EPI-Q and low RSES score. High EPI-Q score was associated high improvement in OHIP-49 score and the ES of the improvement in participants with high EPI-Q was large and exceeded the MID and SEM. Treatment with RDP improves the OHRQoL regardless of level of NA and self-esteem. High NA is associated with a large effect, but both high NA and low self-esteem is associated with poorer OHRQoL both before and after treatment.

Full Text Available Abstract Background Artemisinin-based combination therapy (ACT is recommended as a means of prolonging the effectiveness of first-line malaria treatment regimens. Different brands of mefloquine (MQ have been reported to be non-bioequivalent; this could result in sub-therapeutic levels of mefloquine with decreased efficacy. In 2002, mefloquine-artesunate (MQ-AS combination therapy was adopted as the first-line treatment for uncomplicated Plasmodium falciparum malaria in the Amazon region of Peru. Although MQ resistance has yet to be reported from the Peruvian Amazon, it has been reported from other countries in the Amazon Region. Therefore, continuous monitoring is warranted to ensure that the first-line therapy remains efficacious. This study examines the in vivo efficacy and pharmacokinetic parameters through Day 56 of three commercial formulations of MQ (Lariam®, Mephaquin®, and Mefloquina-AC® Farma given in combination with artesunate. Methods Thirty-nine non-pregnant adults with P. falciparum mono-infection were randomly assigned to receive artesunate in combination with either (1 Lariam, (2 Mephaquin, or (3 Mefloquina AC. Patients were assessed on Day 0 (with blood samples for pharmacokinetics at 0, 2, 4, and 8 hours, 1, 2, 3, 7, and then weekly until day 56. Clinical and parasitological outcomes were based on the standardized WHO protocol. Whole blood mefloquine concentrations were determined by high-performance liquid chromatography and pharmacokinetic parameters were determined using non-compartmental analysis of concentration versus time data. Results By day 3, all patients had cleared parasitaemia except for one patient in the AC Farma arm; this patient cleared by day 4. No recurrences of parasitaemia were seen in any of the 34 patients. All three MQ formulations had a terminal half-life of 14–15 days and time to maximum plasma concentration of 45–52 hours. The maximal concentration (Cmax and interquartile range was 2,820 ng

The aim of this study was to analyze conventional wisdom regarding the construction and analysis of oral health-related quality of life (OHRQoL) questionnaires and to outline statistical complications. Most methods used for developing and analyzing questionnaires, such as factor analysis and Cronbach's alpha, presume psychological constructs to be latent, inferring a reflective measurement model with the underlying assumption of local independence. Local independence implies that the latent variable explains why the variables observed are related. Many OHRQoL questionnaires are analyzed as if they were based on a reflective measurement model; local independence is thus assumed. This assumption requires these questionnaires to consist solely of items that reflect, instead of determine, OHRQoL. The tenability of this assumption is the main topic of the present study. It is argued that OHRQoL questionnaires are a mix of both a formative measurement model and a reflective measurement model, thus violating the assumption of local independence. The implications are discussed.

This study assessed the relation of child oral health-related quality of life with school performance and school absenteeism. We followed a cross-sectional design with a multistage random sample of 312 12-year-old schoolchildren living in Brazil. The participants completed the child perceptions questionnaire (CPQ(11-14) ) that provides information about psychological factors, while their parents or guardians answered questions on their socioeconomic status measured by parents' education level and household income. A dental examination of each child provided information on the prevalence of caries and dental trauma. Data on school performance, which included the results of baseline Brazilian language (Portuguese) tests, and school absenteeism (school days missed) were obtained from the school register. Multilevel linear regression was used to investigate the association among psychological and socioeconomic status and children's school performance. In the multiple model, after adjusting for individual covariates, being a girl was associated with higher school performance (P Children's school performance and absence were influenced by psychological and socioeconomic conditions. © 2012 American Association of Public Health Dentistry.

Xerostomia and tooth loss are major oral health problems in the elderly. The aim of this longitudinal study was to characterize the influence of xerostomia on oral health-related quality of life (OHRQoL) among elderly Japanese people. A total of 99 community-dwelling, independently living individuals aged 60 years and older were interviewed and underwent dental examination at baseline and at a 5-year follow-up. The Oral Health Impact Profile-14 and the Xerostomia Inventory were used to assess OHRQoL and xerostomia severity, respectively. Participants whose xerostomia worsened over the 5-year period had a significantly poorer follow-up OHRQoL. Linear regression models showed that tooth loss and worsening xerostomia were significant predictors of poorer follow-up OHRQoL. Tooth loss and worsening xerostomia result in poorer OHRQoL among older Japanese people. Copyright © 2014 Elsevier Inc. All rights reserved.

This study investigated the relationship between contextual and individual social determinants of oral health-related quality of life (OHRQoL) in Brazilian adults. Data of 4594 Brazilian adults aged 35-44 years from the 2010 Brazilian Oral Health Survey were analysed. OHRQoL was measured using the Oral Impacts on Daily Performance (OIDP). Contextual socio-economic characteristics at city level assessed in 1991 and 2000 included social deprivation measured by Human Development Index (HDI) and income inequality (Gini index). Individual socio-economic characteristics included family income, schooling and number of goods. Covariates were age, sex, ethnicity and clinical oral measures. Multilevel multivariable Poisson regression analysis was carried to investigate the association of contextual and individual social characteristics with OIDP extent and with each OIDP item. Eating and cleaning teeth were the most reported daily activities influenced by oral conditions. In the adjusted analysis, low HDI 1991 and individual social characteristics (lower family income and lower schooling) were associated with OIDP extent. Sex (females) and all clinical oral measures were also associated with OIDP. Adults living in the cities with low HDI 1991 were more likely to have impact on eating and sleeping, whereas living in cities with high Gini index 1991 increased the prevalence of impact on emotional status, work and social contact. Low income was associated with all OIDP items. Poor contextual social determinants and lower individual socio-economic position are associated with worse OHRQoL among Brazilian adults, even after adjusting for individual socio-demographic and clinical oral health variables.

In order to investigate the effect of artesunate combined with irradiation on DNA damage of HeLa and Siha cells of human cervical cancer, HeLa and Siha cells were cultured in vitro and exposed to different concentration of artesunate for 24 h and MTT assay was used to observe the inhibitory effect of different concentration of artesunate on the proliferation of HeLa and Siha cells. The cells were divided into 2 groups as the irradiated group and the union treatment group. Here it was set up four absorbed doses of 60 Co γ-irradiation in each group with 0, 2, 4 and 6 Gy, and the DNA damage were detected by single cell gel electrophoresis assay. MTT analysis showed that the inhibition of artesunate on HeLa and Siha cells of cervical cancer was in concentration-dependent manners. Single cell gel electrophoresis showed that the DNA damage of HeLa cells treated with artesunate was more serious than that treated only with irradiation (P<0.05), but had no such effect on Siha cells. Artesunate can increase the radio-sensitivity of HeLa cells cervical cancer with p53 mutant, but has no such effect on wide type p53 cells. (authors)
Neoplasms of oral cavity make up 2.4% of all neoplasms in male and 1.1% in female population of Poland. Treatment of neoplasms in this area is mainly surgical and leads to a smaller or larger disability with a disorder of basic physiological functions such as breathing, swallowing and speech. It leads as well to the creation of psychological symptoms such as anxiety, depression. Lack of available data in Polish literature as well as in foreign literature on the subject of psychological state and quality of life of those patients, convinced me to start research in this area. The research was conducted on a group of 131 patients aged 44-82 years. The patients were divided into three groups: group I consisted of patients after surgical procedures in the face area, group II of patients with serious prognosis (leukaemia) and group III of healthy patients. All patients were subject to survey, which consisted of 2 parts. First part contained 7 questions and related to patient's knowledge as to prognosis for further life (this part pertained patients from group I and II). Second part of the questionnaire was a shortened version of a depression scale based on 15 traits and short version based on 4 traits. It was adopted, that this is a good research tool in case of depression, since it is directed exclusively on diagnosis of depression symptoms. Short research technique facilitates the patient to answer questions asked. The results were interpreted according to depression rating scale. The research indicated that amongst patients after surgical procedures; over 50% of women and almost 40% of man showed intensified growth of depression. This percentage was significantly lower in the group of patients with serious prognosis. In the healthy group, all of the women and over 80% of men had no depression. Education statistically had no significant influence on the depression level. It can be ascertained that surgical procedures in the facial area and oral cavity have influence

To evaluate whether orthodontic treatment in adults requiring oral rehabilitation is effective for increasing patients' self-esteem and quality of life (QoL). The sample consisted of 102 adult patients (77 women and 25 men) aged between 18 and 66 years (mean, 35.1 years) requiring oral rehabilitation and orthodontic treatment simultaneously. Rosenberg's Self-Esteem (RSE) Scale and a questionnaire about QoL based on the Oral Health Impact Profile (OHIP-14) were used to determine self-esteem and QoL scores retrospectively. Questionnaires were carried out in two stages, T1 (start of treatment) and T2 (6 months after). To compare score changes between T1 and T2, the data obtained from the RSE Scale were evaluated with paired t tests, and data from the quality-of-life questionnaire were assessed by applying descriptive statistics. The results showed a statistically significant increase in self-esteem (P < .001) and a great improvement on patients' QoL. Orthodontic treatment causes a significant increase in self-esteem and QoL, providing psychological benefits for adult patients in need of oral rehabilitation.

Artemisinin is extracted from Artemisia annua, a shrub also known as sweet wormwood that was used in traditional medicine in Asia for more than 1500 years. Recent studies in numerous malarious zones have demonstrated the effectiveness of artemisinin and have reported no evidence of the resistance now associated with almost all other antimalarials on the market. Despite its remarkable activity, artermisinin is not accessible to many patients due to high cost. This situation confronts all players in the fight against malaria with the urgent need to develop a simple process to produce massive supplies of artemisinin and its derivative at an affordable price. The purpose of the study described here was to develop a simple, cost-effective method that could be used by all professionals to extract artemisinin and transform it into artesunate or artemether. Artemisinin was extracted with dichloromethane and purified on the basis of variations in polarity and in the hydrophile/lipophile balance of solvents. Transformation into artesunate was a two-step process involving reduction to dihydroartemisinin using diisobutylaluminium hydride (DIBAL) followed by esterification using succinic anhydride. Artemether was obtained from dihydroartemisinin using boron trifluoride. Extraction using dichloromethane presents several advantages. Since dichloromethane is not explosive it can be safely transported and used for extraction on farms where Artemisia annua is grown. Evaporation and recovery of dichloromethane is relatively easy so that it can be re-used. These advantages result in a significant decrease in purchasing and shipping costs. Extraction on the farm eliminates the expense and facilities that would otherwise be required to transport and store leaves at the laboratory (250 kg of leaves yield 4 to 5 kg of raw artemisinin extract that yields approximately 1 kg of pure artemisinin). The low-cost process described here is feasible for any pharmaceutical laboratory including

The availability of numerous brands of artesunate in our drug market today places clinicians and pharmacists in a difficult situation of choice of a suitable brand or the possibility of alternative use. Fake artesunate could compromise the hope that ACT (artemisinin combination therapy) offers for malaria control in Africa. In this study, quality of some selected brands of anti - malarial drugs used in the communities of Agona west Municipality, Ghana was determined. Blister or packs of anti – malarial tablets were randomly sampled. The Protocols of the International Pharmacopeia and Global Pharma Health Fund Minilab were used to assess the quality of anti – malarial tablets per blister pack manufactured by Bliss Gvs Pharma Ltd. India, Letap Pharmaceutical Company Ltd. Ghana and Guilin Pharmaceutical Company Ltd. China and sold in chemical sales outlets at the farming communities of Agona West Municipality, Ghana. The identification test was used to confirm the presence of active ingredients in the tablets. A confirmatory test for the active ingredient was achieved with artesunate (ICRS 1302) reference standards and Gsunate reference standard (ICRS4061). The friability test was used to confirm the hardness of the tablets to determine the drug ability to withstand abrasion in packaging, handling and shipping. The disintegration test was used to confirm the time required for the tablets to disintegrate into particles. Titrimetric analysis confirmed the amount of artesunate found in tablets.The results of the study are as follows for Artesunate by GPCL, LPL and Gsunate by BGPL; the identification test confirmed the presence of the active ingredient in all the brands. Based on the International Pharmacopoeia acceptable range of 1 to 15 min for genuine artesunate per tablet, 93.75 % of field selected artesunate blister pack tablets manufactured by GPCL passed the disintegration test and 6.25% failed. Also 85.57% of the sampled artesunate blister pack manufactured by

In the present study, we examined the influence of kindergarten component skills on writing outcomes, both concurrently and longitudinally to first grade. Using data from 265 students, we investigated a model of writing development including attention regulation along with students’ reading, spelling, handwriting fluency, and oral language component skills. Results from structural equation modeling demonstrated that a model including attention was better fitting than a model with only language and literacy factors. Attention, a higher-order literacy factor related to reading and spelling proficiency, and automaticity in letter-writing were uniquely and positively related to compositional fluency in kindergarten. Attention and higher-order literacy factor were predictive of both composition quality and fluency in first grade, while oral language showed unique relations with first grade writing quality. Implications for writing development and instruction are discussed. PMID:25132722

This study examined the caregivers' perception of the effect of dental conditions on general well-being and family life of a group of human immunodeficiency virus (HIV)-infected Nigerian children. A secondary aim was to investigate correlations between the children's sociodemographic and health-related variables and caregivers' global ratings of oral health and well-being. Study Design A cross-sectional questionnaire-based survey was conducted among parents/caregivers of 95 HIV-positive children receiving care at the Lagos State University Teaching Hospital, Nigeria. The "Parental-Caregivers Perception Questionnaire" which included measures of global ratings of oral health and well-being as well as effects of oral health on domains of oral symptoms, functional limitations, emotional well-being, and family well-being/parental distress was used. Assessment was based on the child's oral health within the preceding 3 months of the study. The most affected subscale of the oral health-related quality of life was functional limitation followed by parental distress and then oral symptoms. Caregivers of older children were 2½ times more likely to view oral health as impacting their child's overall health (P = 0.034). Furthermore, caregivers of children who had not yet commenced antiretroviral therapy were 15% more likely to report oral symptoms (P = 0.024) and 11% were more likely to be distressed. Data entry, validation, and analysis were done using SPSS version 17.0. Findings were considered to be statistically significant when 95% confidence intervals were not overlapping. According to caregivers' perceptions, oral symptoms, functional limitations, and parental distress outweighed emotional well-being in impacting a child's oral health quality of life. Oral health programs to improve the knowledge of caregivers on the importance of oral health in HIV-positive children are necessary for improvement in overall quality of life.

Baclofen commonly is used to manage spasticity caused by central nervous system lesions or dysfunction. Although both intrathecal and oral delivery routes are possible, no study has directly compared clinical outcomes associated with these 2 routes of treatment. To compare spasticity levels, pain, sleep, fatigue, and quality of life between individuals receiving treatment with intrathecal versus oral baclofen. Cross-sectional matched cohort survey study. Urban academic rehabilitation outpatient clinics. Adult patients with spasticity, treated with intrathecal or oral baclofen for at least 1 year, matched 1:1 for age, gender, and diagnosis. Standardized surveys were administered during clinic appointments or by telephone. Surveys included the Penn Spasm Frequency Scale, Brief Pain Inventory, Epworth Sleepiness Scale, Fatigue Severity Scale, Life Satisfaction Questionnaire, and Diener Satisfaction with Life Scale. A total of 62 matched subjects were enrolled. The mean (standard deviation [SD]) age was 46 (11) years with a mean duration of intrathecal baclofen or oral baclofen treatment of 11 (6) and 13 (11) years, respectively. There were 40 (64%) male and 22 (36%) female subjects. Primary diagnoses included spinal cord injury (n = 38), cerebral palsy (n = 10), stroke (n = 10), and multiple sclerosis (n = 4). The mean (SD) dose of intrathecal and oral baclofen at the time of survey were 577 (1429) μg/day and 86 (50) mg/day, respectively. Patients receiving intrathecal compared with oral baclofen experienced significantly fewer (1.44 [0.92] versus 2.37 [1.12]) and less severe (1.44 [0.92] versus 2.16 [0.83]) spasms, respectively as measured by the Penn Spasm Frequency Scale (P life between groups. Subanalysis of patients with SCI mirrored results of the entire study sample, with significant decreases in spasm frequency and severity associated with intrathecal compared to oral baclofen (P < .01; P < .01), but no other between group differences.

To assess the relationship of child oral health-related quality of life and socioeconomic backgrounds to traumatic dental injuries in schoolchildren. This study followed a cross-sectional design, with a multistage random sample of 792 12-year-old schoolchildren, representative of Santa Maria, a city in southern Brazil. The participants completed the Brazilian version of the Child Perceptions Questionnaire (CPQ11-14), their parents or guardians answered questions on socioeconomic status, and a dental examination provided information on the prevalence of dental trauma. The assessment of association used Poisson regression models. The prevalence of TDI was 9.7%. The maxillary central incisors were the most frequently traumatised, and the most commonly observed traumatic dental injury was enamel fracture. No association was observed among child oral health-related quality of life and socioeconomic factors with traumatic dental injuries after the adjustment. Socioeconomic indicators are not associated with dental trauma in schoolchildren and this oral health condition has no negative impacts on children's quality of life.

Although the use of removable dentures can improve oral function and esthetics for elderly people, compared to those who do not wear removable dentures, those wearing removable dentures could have worse oral health related-quality of life (OHRQoL). Additional information is required to assess which factors related to denture wearing influence the OHRQoL of elderly individuals. The purpose of this study is to evaluate the association between denture wearing and OHRQoL in a sample of elderly individuals in Taiwan. The study population included 277 elderly people wearing removable dentures (mean age = 76.0 years). Using face-to-face interviews, we collected data on the participants' socio-demographic characteristics, dental care service usage (regular dental checkups, treatment during toothache, dental visits in the last year), and factors related to denture wearing (perceived oral pain, perceived loose denture, perceived oral ulcer, perceived halitosis, perceived dry mouth, and perceived total denture satisfaction scores). OHRQoL was measured using the Taiwanese version of the Geriatric Oral Health Assessment Index (GOHAI-T). The location and number of remaining natural teeth and the type of denture were also recorded. Hierarchical multiple regression analysis was performed using GOHAI-T scores as the dependent variable. All the predictors together accounted for 50% of the variance in GOHAI-T scores. Further, education level, number of natural teeth, denture status, perceived loose denture, perceived oral ulcer, and perceived total denture satisfaction scores had statistically significant influences on OHRQoL. When compared with other variables, factors related to denture wearing, especially perceived total denture satisfaction scores, had the greatest impact on GOHAI-T scores. Of the factors analyzed in this study, denture satisfaction was the strongest predictor of OHRQoL. This suggests that denture satisfaction is useful for assessing the effect of denture

Full Text Available The aim of this study was to identify the impact of oral disease on the quality of life of morbid obese and normal weight individuals. Cohort was composed of 100 morbid-obese and 50 normal-weight subjects. Dental caries, community periodontal index, gingival bleeding on probing (BOP, calculus, probing pocket depth, clinical attachment level, dental wear, stimulated salivary flow, and salivary pH were used to evaluate oral diseases. Socioeconomic and the oral impacts on daily performances (OIDP questionnaires showed the quality of life in both groups. Unpaired Student, Fisher's Exact, Chi-Square, Mann-Whitney, and Multiple Regression tests were used (p<0.05. Obese showed lower socio-economic level than control group, but no differences were found considering OIDP. No significant differences were observed between groups considering the number of absent teeth, bruxism, difficult mastication, calculus, initial caries lesion, and caries. However, saliva flow was low, and the salivary pH was changed in the obese group. Enamel wear was lower and dentine wear was higher in obese. More BOP, insertion loss, and periodontal pocket, especially the deeper ones, were found in obese subjects. The regression model showed gender, smoking, salivary pH, socio-economic level, periodontal pocket, and periodontal insertion loss significantly associated to obesity. However, both OIDP and BOP did not show significant contribution to the model. The quality of life of morbid obese was more negatively influenced by oral disease and socio-economic factors than in normal weight subjects.

Mefloquine-artesunate combination therapy for uncomplicated falciparum malaria is one of the treatments used in African children. Data concerning neurological safety in adults and children treated with mefloquine and artesunate combination therapy is well documented in Asia. Safety data for neurological and neuropsychiatric side effects of mefloquine and artesunate combination therapy in African children are scarce, although WHO recommends this therapy in Africa. A phase IV, open label, single arm study was conducted among African children between 10 and 20 kg with acute uncomplicated falciparum malaria. They were treated over three consecutive days with a paediatric fixed-dose combination of artesunate (50 mg/d) and mefloquine (125 mg/d). Parasitological, clinical and neurological examinations and standardized questions about neuropsychiatric symptoms were carried out on days 0, 4, 7, 28 and 63. The primary objective was to assess the neurological and neuropsychiatric safety of artesunate-mefloquine combination therapy in young children. From December 2007 to March 2009, 220 children with uncomplicated Plasmodium falciparum malaria were treated with artesunate and mefloquine. 213 children were analysed according to study protocol. 50 neurological and neuropsychiatric adverse events occurred in 28 patients. Eleven drug-related neurological and neuropsychiatric adverse events occurred in eight patients. Sleeping disorders were present in 2.3%, neurological disorders in 1.4%, neuropsychiatric disorders in 1% and eating disorders in 0.5% of the patients. Adverse events were of mild to moderate intensity and resolved spontaneously. African children showed a low percentage of self-limited neurological and neuropsychiatric adverse events, confirming studies on neurological safety in Asian children treated with artesunate and mefloquine. Sleeping disorders were most frequently observed.

The aim of this cross-sectional study was to evaluate the impact of oral health conditions, socioeconomic status and use of specific substances on quality of life of alcohol and drug addicted persons, receiving care at outpatient treatment facilities in Brazil. A random sample of 262 participants, mean age 37 years, from Psychosocial Care Centers for Alcohol and Drugs (CAPS AD) located in three cities in the state of São Paulo, Brazil, were clinically examined for caries experience (DMFT index) by a calibrated examiner. They were asked to complete a series of questionnaires, including the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), socioeconomic characteristics, and the World Health Organization Quality of Life assessment (WHOQOL), which were considered the outcome variables of the study. Associations between oral health status, socioeconomic characteristics, substance involvement with WHOQOL were investigated by means of the chi-square test and multiple logistic regression analysis with a level of significance α 14 (OR = 2.25; CI 95% = 1.30-3.89); low-income (OR = 2.41; CI 95% = 1.22-4.77) and users of cocaine/crack (OR = 2.02; CI 95% = 1.15-3.59) were more likely to have poor general quality of life. This study demonstrated that the general quality of life of addicted persons was associated with caries experience, low income and cocaine/crack use.

Rare earth intensifying screen material (Gd2O2S:Tb) was added to the standard Al filtration of an oral panoramic x-ray unit, resulting in a beam capable of achieving reductions in patient dose without a loss of image quality. The added rare earth filtration technique resulted in patient dose reductions of 21-56%, depending on anatomic sites, when compared to the conventional Al filtration technique. Films generated from both techniques were measured densitometrically and evaluated by a panel of practicing clinicians. Diagnostically significant differences were minimal. The results indicate that use of rare earth filters in oral panoramic radiography is an effective means of reducing exposures of dental patients to ionizing radiation

This study aims to evaluate the quality of life (QOL) of patients who underwent resection of oral cancer and reconstruction by free anierolateral thigh perforator flaps (ALTF). A total of 32 patients with oral and maxillofacial malignancies who had undergone the resection of oral cancer and reconstruction by ALTF were retrospectively analyzed. At 12 months postoperatively, the QOL of these patients was assessed by using the 14-item oral health impact profile (OHIP-14) and the medical outcome study short form-36 (SF-36) questionnaires. A total of 32 questionnaires were collected. In SF-36, the highest scoring domains were bodily pain (78.58 ± 14.82), physical functioning (72.08 ± 27.86), and the role of physical (60.00 ± 42.63), whereas the lowest scoring domains were role-emotional (41.67 ± 39.62), followed by mental health (50.75 ± 13.07) and health transition (54.17 ± 21.75). In OHIP-14, the lowest scoring domains were social disability (34.50 ± 11.32) and handicap (36.04 ± 12.05), indicating the functional recovery was better; and the highest scoring domains were physical pain (73.50 ± 18.96) and psychological discomfort (60.17 ± 20.66), indicating the functional recovery was worse. The ALTF is an ideal selection for the reconstruction of oral defects after cancer resection. In using this flap, the basic social need of patients after surgery can be satisfied. Moreover, the appearance and the functions of chewing, deglutition, and speech can be restored in varying degrees. Thus, ALTF can improve the patients' QOL.

Aspects of oral health related quality of life (OHRQoL) attracted an increased attention recently. The aim of the study was to assess self-reported oral health related quality of life (OHRQoL) among patients requiring prosthetic rehabilitation and to determine the rate of improvement 1 month and 6-12 months after therapy. In addition, effect of age, gender, oral health indicators and denture types before treatment were assessed on OHRQoL as evaluated and reported by the patients. Hungarian version of OHIP-49 (OHIP-49-H) questionnaire was completed before oral rehabilitation (T0-phase) by 389 patients undergoing prosthetic replacement. After 1 month (T1-phase) and 6-12 months (T2-phase) recall periods 235 and 92 patients completed the questionnaire. The median interquartile range (IQR) values of the total OHIP-49-H score were calculated for T0-, T1- and T2-phases. Reliability of the questionnaire was checked by Cronbach's statistics. Age, gender, oral health indicators and denture types of patients before and after treatment were recorded and treatment-associated changes in OHRQoL were evaluated. The study demonstrated the excellent reliability and internal consistency of OHIP-49-H by a high and narrow range of Cronbach's alpha value (0.81-0.93). A median OHIP-49-H score of 52; IQR = 25-83 demonstrated a poor OHRQoL on first admission. Decreasing median total OHIP-49-H scores 1 month (24; IQR = 9-51; p < 0.001) and 6-12 months (20; IQR = 7-37; p = 0,055) after therapy indicated an improvement of OHRQoL. Patients' age and CPI value assessed before treatment proved to be significant factors of OHRQoL. Here we presented representative data about self-assessed OHRQoL of patients requiring prosthetic treatment from Hungary using OHIP-49-H questionnaire. The results demonstrated that the restoration of oral health was associated with an improvement in patients' OHRQoL. According to the demographical and T0 phase clinical status, the treatment was more

Oral Health-Related Quality of Life (OHRQoL) indicates an individual's perception of how their well-being and quality of life is influenced by oral health. It facilitates treatment planning, assessing patient centred treatment outcomes and satisfaction. The study aimed to identify the factors influencing OHRQoL among Tamil speaking South Indian adult population. Non-probability sampling was done and 199 subjects aged 20-70 years were recruited for this observational study. The subjects were requested to fill a survey form along with the validated Tamil General Oral Health Assessment Index (GOHAI-Tml) questionnaire in the waiting area following which clinical examination was done by a single experienced Periodontist. The mean score with standard deviation for physical dimension was 4.34±0.96, psychological dimension was 4.03±1.13 and pain was 4.05±1.09 on GOHAI. Greater impacts were seen for psychosocial dimensions like pleased with the appearance of teeth/denture Q7 (3.7±1.2), worried about the problems with teeth/denture Q9 (3.7±1) and pain or discomfort in teeth Q12 (3.8±1). Functions like swallowing Q3 (4.5±0.8) and speaking Q4 (4.6±0.7) were minimally affected. As age increased subjects perceived more negative impacts as indicated by lower ADD-GOHAI and higher SC-GOHAI scores (p<0.01). Subjects complaining of bad breath, bleeding gums and Temporomandibular Joint (TMJ) problems, reported poor OHRQoL (p<0.05). It was observed that as self-perceived oral and general health status deteriorated, OHRQoL also worsened (p<0.01). Subjects with missing teeth, cervical abrasion, restorations, gingival recession and mobility had more impacts on OHRQoL (p<0.05). Subjects diagnosed with periodontitis had lower OHRQoL as reported on the scale than gingivitis subjects (p<0.01). In this study minimal impact was seen in all the three dimensions assessed with GOHAI. Factors like age, education, employment status, income, self-reported oral health, self-perceived general

The aim of this study was to evaluate the effects of chronic pain on oral health related quality of life (oral QoL) in patients with anterior disc displacement with reduction (DDwR). Thirty-seven patients who had disc displacement with reduction (DDwR, F/M: 23/14, median age: 29, range: 23-49) were selected. These patients had chronic pain and had not been undergoing any treatment protocols for the previous six months. Age- and gender-matched healthy subjects healthy control, F/M: 23/14, mean age: 33.0 +/- 15.7 years) were used as a control group. Data were collected by means of a clinical examination and a questionnaire about pain status which included a jaw disability checklist RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders). Pain status was scored between 0 (no pain) and 10 (poor pain status) by the patients. Oral health related quality of life (oral QoL) over the previous six months was evaluated by an oral health impact profile-14 (OHIP-14) questionnaire. OHIP-14 score was significantly higher in patients with DDwR (median:17, min-max:6-39) than healthy controls (9, 0-18) (p = 0.000). The median duration of orofacial pain was 12 (range 7-120) months. Statistically significant correlations were observed between OHIP-14 score and the worst pain intensity in the past six months (7, 0-10) (r = 0.5 p = 0.007) and average pain intensity in the past six months (5.5, 1-10) (r = 0.4 p = 0.018). In addition, an increase in OHIP-14 score was observed in patients experiencing difficulty in smiling/laughing, cleaning their teeth or face, swallowing or talking, according to the jaw disability checklist (p = 0.042, p = 0.001, p = 0.023 and p = 0.007, respectively). Poor oral QoL was related to chronic pain and limitations in jaw function in patients with DDwR.
Full Text Available Abstract Background The World Health Organization (WHO recommends injectable artesunate given either intravenously or by the intramuscular route for definitive treatment for severe malaria and recommends a single intramuscular dose of intramuscular artesunate or intramuscular artemether or intramuscular quinine, in that order of preference as pre-referral treatment when definitive treatment is not possible. Where intramuscular injections are not available, children under 6 years may be administered a single dose of rectal artesunate. Although the current malaria treatment guidelines in Ethiopia recommend intra-rectal artesunate or alternatively intramuscular artemether or intramuscular quinine as pre-referral treatment for severe malaria at the health posts, there are currently no WHO prequalified suppliers of intra-rectal artesunate and when available, its use is limited to children under 6 years of age leaving a gap for the older age groups. Intramuscular artesunate is not part of the drugs recommended for pre-referral treatment in Ethiopia. This study assessed the perspectives of health workers, and policy-makers on the use of intramuscular artesunate as a pre-referral and definitive treatment for severe malaria at the health post level. Methods In-depth interviews were held with 101 individuals including health workers, malaria focal persons, and Regional Health Bureaus from Oromia and southern nations, nationalities, and peoples’ region, as well as participants from the Federal Ministry of Health and development partners. An interview guide was used in the data collection and thematic content analysis was employed for analysis. Results Key findings from this study are: (1 provision of intramuscular artesunate as pre-referral and definitive treatment for severe malaria at health posts could be lifesaving; (2 with adequate training, and provision of facilities including beds, health posts can provide definitive treatment for severe
Full Text Available Abstract Background Declining in clinical efficacy of artesunate-mefloquine combination has been documented in areas along the eastern border (Thai-Cambodian of Thailand. In the present study, the clinical efficacy of the three-day combination regimen of artesunate-mefloquine as first-line treatment for acute uncomplicated falciparum malaria in Thailand was monitored in an area along the western border (Thai-Myanmar of the country. Methods A total of 150 Burmese patients (85 males and 65 females aged between 16 and 50 years who were attending the Mae Tao clinic, Mae-Sot, Tak Province, and presenting with symptomatic acute uncomplicated Plasmodium falciparum malaria were included into the study. Patients were treated initially (day 0 with 4 mg/kg body weight artesunate and 15 mg/kg body weight mefloquine. The dose regimen on day 2 was 4 mg/kg body weight artesunate and 10 mg/kg body weight mefloquine. On day 3, artesunate at the dose of 4 mg/kg body weight was given with 0.6 mg/kg body weight primaquine. Whole blood mefloquine and plasma artesunate and dihydroartemisinin (active plasma metabolite of artesunate concentrations following treatment were determined by high performance liquid chromatography (HPLC and liquid chromatography-mass spectrometry (LCMS, respectively. Results Thirty-four cases had recrudescence during days 7 and 42. Five and 5 cases, respectively had reinfection with P. falciparum and reappearance of Plasmodium vivax in their peripheral blood during follow-up. The Kaplan-Meier estimate of the 42-and 28-day efficacy rates of this combination regimen were 72.58% (95% CI: 63.20-79.07% and 83.06 (95% CI 76.14-94.40%, respectively. Parasite clearance time (PCT and fever clearance time (FCT were significantly prolonged in patients with treatment failure compared with those with sensitive response [median (95% CI values for PCT 32.0 (20.0-48.0 vs 24.0 (14.0-32.0 hr and FCT 30.0 (22.0-42.0 vs 26.0 (18.0-36.0 hr; p vs 525 (452-599 ng
Full Text Available Objective: Age and tooth loss are expected to have a complex relationship with oral health-related quality of life. So the purpose of this study was to explain the impact of age and tooth loss on oral health-related quality of life using the short form 14-item oral health impact profile (OHIP-14 among two population samples of Gujarat and Rajasthan.Materials and Methods: A cross-sectional questionnaire-based survey was conducted among 1441 subjects collected from two major cities of Gujarat and Rajasthan. Both questionnaire approaches using OHIP-14 scale and clinical examination were conducted in accordance with WHO criteria using type III procedure on the same day. Chi square test, ANOVA and stepwise multiple regression analysis were applied using SPSS software version 15.0.Results: With the increase of age, OHIP mean score in both states increased, but that among Rajasthan state was higher, depicting poor oral health. Whereas, in the remaining 23-27 number of teeth both states showed higher OHIP mean, however again the score was much higher among Rajasthan subjects showing worse oral hygiene. Hence, overall all mean OHIP score for Gujarat was lower indicating good oral health; whereas, that among Rajasthan was higher indicating poor oral health-related quality of life.Conclusion: Both age and tooth loss are associated with each other, but they have an independent effect on the oral health-related quality of life. Thus, all studied populations with complete natural dentition showed good oral health-related quality of life.

To analyze the influence of dental treatment on oral health-related quality of life (OHRQoL) in head and neck cancer patients. This study included the data of 116 patients who underwent radiotherapy (RT) because of head and neck cancer. For each patient, the variables age, sex, tumor site, irradiation technique, dose on the spared parotid gland, concomitant chemotherapy, and denture status were documented. OHRQoL was determined using the OHIP-G14 questionnaire. Patients were divided into subgroups according to denture status: none or fixed partial dentures (none/FPD), removable partial dentures (RPD), and full dentures (CD). OHIP summary scores were determined and tested for clinical relevant differences with respect to the different variables. The association between OHRQol and the variables was assessed using linear regression. No clinically relevant influence on OHRQoL was found for gender, irradiation technique, and chemotherapy. Patients with tumors located in the oral cavity had a significantly higher OHIP score than patients with other tumor sites (p < 0.001). None/FPD and RPD patients had higher values than those found in a normal population, but did not differ significantly from each other (p = 0.387). In contrast to tumor site, teeth and type of denture seem to have a limited effect on OHRQoL in head and neck cancer patients. Prosthetic treatment in head and neck cancer patients do not lead to the same improvement in OHRQoL as found in the normal population. This might be taken into account especially if extensive dental treatment is intended.

The impact of oral cancer and its treatment is well documented; therefore, oral rehabilitation (OH; eg, with prosthetics, osseointegrated implants, etc) can be indicated to restore some level of form, function, and well-being. The purpose of this study was to review the current literature and evaluate the impact of OH on quality of life (QoL) after ablative surgery. A systematic literature search was conducted using EMBASE, MEDLINE, and PsychINFO. The study population was composed of all articles published from 2000 to 2015. To be included, studies had to use validated, specific head and neck QoL measurements (European Organization for Research and Treatment of Cancer QoL Head and Neck Module or University of Washington QoL Questionnaire). Only 8 articles met these inclusion criteria. In this review, OH was the primary predictor variable and QoL was the primary outcome variable. The 8 articles reviewed used a range of designs, including 1 randomized controlled trial, 3 prospective cohort studies, 3 case series, and 1 single-measurement cross-sectional descriptive study. Sample sizes were small (n = 26 to 102), and there was limited randomization and control of intervention and comparator groups. The overall level of evidence was weak. All studies showed a link between OH and QoL, but the results varied in significance (P < .01 to P = .95). Overall, there appears to be improvement in QoL to varying degrees after OH. However, a more systematic use of QoL measurements is needed before any definitive conclusions can be drawn. Crown Copyright © 2016. Published by Elsevier Inc. All rights reserved.

To assess self-perceived oral health-related quality of life (OHRQoL) in 12-year-olds living in two areas in the Barents region: North-West Russia (Arkhangelsk) and Northern Norway (TromsÃ¸). Sampling was performed according to a stratified cluster design and consisted of 590 Russian and 264 Norwegian 12-year-olds and their parents. After written consent from their parents, 514 Russian (87% attendance) and 124 Norwegian (47% attendance) children entered the study. The study included clinical examination (children) and questionnaires (children and parents). Dental caries and the aesthetic dental appearance were recorded under field conditions. Self-reports on background variables and oral health-related quality of life questions (CPQ11-14) were completed in classroom settings by children and at home by parents. OHRQoL was found to vary depending on country of origin, with higher scores of CPQ11-14 domains among 12-year-olds from Russia. OHRQoL was found to be associated with dental caries, with higher scores among 12-year olds with caries. Inferior emotional and social well-being were established as having the strongest association with quality of life. Dental caries showed an independent effect on OHRQoL scores, but this effect disappeared when controlling for background variables, with country of origin, family economy, parental education and aesthetic appearance as the most influential (RÂ²=0.14). Norwegian 12-year-olds had better oral health and OHRQoL than their Russian counterparts. The impact of dental caries on OHRQoL was weak and aesthetic dental appearance and socio-economic determinants were found to be more important, probably reflecting the great differences in the standards of living between Northern Norway and North-West Russia.

The process of ageing influences all dimensions of social life and personal well-being, but the influence of health on different dimensions of quality of life (QoL) among the elderly is rarely examined. The aim of the pilot study is to test the feasibility of a comprehensive study design to evaluate general and dental health as well as QoL in a bi-national sample. In addition, this pilot study should allow for the exploration of potential interactions between QoL, socioeconomic, health and oral health variables. Individuals aged 64 years and older (n = 100) from university dental clinics of the Wroclaw Medical University, Poland (n = 50) and of the University Hospital in Dresden, Germany (n = 50) were examined. The oral health status of participants was assessed by clinical examination. Socio-demographic, environmental and general health status were evaluated during the medical interview. General quality of life (GQoL) was assessed by an overall question with a visual analogue scale (VAS) from -5 (worst) to +5 (best). Health-related quality of life (HRQoL) and oral health-related quality of life (OHRQoL) were measured with the EQ-5D and OHIP-14 questionnaires. Statistical analyses comprised Pearson's c2 test, Wilcoxon test, linear regression model for statistical analysis and different multivariate linear regression analyses. For the GQoL-VAS-Score the results for QoL measurements were 1.22 ± 2.62 (x± SD), for EQ-5D-Score 7.45 ± 2.25 (x± SD), and for OHIP-14-ADD-Score 11.04 ± 13.56 (x± SD). Differences between Polish and German populations were observed. The study design proved to be feasible for a senior population. The overall GQoL question, EQ-5D and OHIP-14 were regarded as appropriate instruments. Subjective and objective (oral) health measures showed differences between Germany and Poland. For methodological reasons, these differences are not generalizable, but of value for study hypotheses in larger samples.

The purpose of this study was to clarify the impact of orthognathic surgery on oral health-related quality of life (OHRQOL) in patients with jaw deformities. The subjects were 65 patients (21 males and 44 females) who underwent orthognathic surgery. The mean age of the patients was 23.6 years. Forty-seven patients had skeletal class III malocclusions, eight patients had skeletal class II, and 10 patients had skeletal class I with facial asymmetry and/or open bite. OHRQOL was assessed using the Japanese version of the Oral Health Impact Profile (OHIP-J54) before and 6 months after surgery. While OHIP-J54 scores in the patients before surgery were significantly higher than those in the control subjects, OHIP-J54 scores after surgery were significantly lower than those before surgery. OHIP-J54 scores in older patients were significantly higher than those in younger patients. In conclusion, most patients with jaw deformities have lower OHRQOL than individuals with normal occlusion, and orthognathic surgery has a positive impact on OHRQOL. The determination of OHRQOL in patients with jaw deformities seems to be very useful for understanding the patients' problems and for assessing the extent of changes in terms of patient well-being.

The aim of this study was to investigate the impact of the use of crack and other illicit drugs on oral health-related quality of life (OHRQoL) in young adults. This cross-sectional study evaluated 106 crack users at a public treatment center for drug addiction and 106 controls matched for gender, age, and use of tobacco. Clinical examinations were performed for dental caries and periodontal disease. The outcome was OHRQoL, which was determined using the Oral Health Impact Profile (OHIP-14). The association between OHRQoL and illicit drugs was modeled using conditional Poisson regression. Users of crack and other illicit drugs had a poorer OHRQoL than the controls (p illicit drugs. Users of crack and other illicit drugs exerted a negative impact on OHRQoL independently of socio-demographic characteristics and tobacco use, suggesting the need for special attention regarding the specific oral health needs of this population as well as drug prevention and treatment strategies. © 2017 John Wiley & Sons A/S.

In order to guide the antimalarial treatment policy of Somalia, we conducted therapeutic efficacy studies of routinely used antimalarial monotherapies as well as artemisinin-based combination therapies (ACTs) for uncomplicated malaria in three sentinel sites during 2003-2006. Therapeutic efficacy of chloroquine (CQ), amodiaquine (AQ) and sulfadoxine/pyrimetahmine (SP) monotherapies, and artesunate plus SP (AS+SP) or AQ (AS+AQ) were evaluated in children 6 months to 10 years old with uncomplicated malaria. For the assessment of the monotherapies, 2003 WHO protocol with 14-day follow-up was used while the 2005 WHO protocol with 28-day follow-up was used for testing the ACTs. Of the monotherapies, CQ performed very poorly with treatment failures varying from 76.5% to 88% between the sites. AQ treatment failure was low except for Janale site with treatment failure of 23.4% compared to 2.8% and 8% in Jamame and Jowhar, respectively. For SP, treatment failures from 7.8% to 12.2% were observed. A 28-day test of artemisinin-based combinations, AS+SP and AS+AQ, proved to be highly efficacious with cure rates of 98-100% supporting the choice of AS+SP combination as first line treatment for uncomplicated malaria for Somalia.

Community-based interventions using artemisinin-derived suppositories may potentially reduce malaria-related childhood mortality. However, their sociocultural acceptability is unknown in Papua New Guinea and a formal examination of caregiver's attitudes to rectal administration was needed to inform effective deployment strategies. Caregivers (n = 131) of children with uncomplicated malaria were questioned on their prior experience with, and attitudes to, rectal administration and then offered artesunate suppositories as treatment of their child. The 29% who refused this alternative were further questioned to determine their reasons for this refusal. Lack of spousal approval and fear of side effects were the most common reasons for refusal. Sixty-six percent of caregivers agreed to self-administer suppositories, which were perceived as effective (99%), safe (96%), and fast-acting (91%), but problematic to administer to a struggling child (56%). Shame, embarrassment, and hygiene were not significant concerns. Acceptability of rectal administration should be relatively high in Papua New Guinea. However, deployment must be accompanied by health education that addresses the practical aspects of administration, is appropriate for the illiterate, and is directed at fathers as well as mothers.
Full Text Available Artesunate (ART is a semisynthetic derivative of artemisinin. Artemisinin and its derivatives have shown profound cytotoxicity and antitumor activity in addition to antimalarial activity in various studies. As the in vivo chemopreventive efficacy of ART in colon carcinogenesis has not been investigated so far, the aim of the current study was to study the chemopreventive effect of ART in 1,2-dimethylhydrazine (DMH-induced rat colon carcinogenesis. Animals were divided into four groups (n = 6: Group I - vehicle (1 mM ethylenediaminetetraacetic acid, Group II - DMH (20 mg/kg, Group III - DMH + 5-fluorouracil (81 mg/kg, Group IV - DMH + ART (6.7 mg/kg. After completion of 15 weeks of treatment, rats were sacrificed under ether anesthesia by cervical dislocation for assessment of lipid peroxidation (LPO, antioxidant status, average number of aberrant crypt foci (ACF, and cytokine levels. ART administration significantly decreased the average number of ACF/microscopic field. Similarly, LPO level was decreased and antioxidant activities were enhanced after ART treatment. ART decreased the levels of proinflammatory cytokines and induced apoptosis in the colons of DMH-treated rats. The results of this study suggest that ART has a beneficial effect against chemically induced colonic preneoplastic progression in rats.

Full Text Available Abstract Background Information on oral health-related quality of life, in addition to clinical measures, is essential for healthcare policy makers to promote oral health resources and address oral health needs. Objectives This paper aimed at evaluating the psychometric properties of the Arabic version of Child-OIDP, estimating the prevalence, severity and causes of oral impacts on daily performances in 12-year-old public and private school attendees in Khartoum State and to identify socio-demographic and clinical correlates of oral impacts as assessed by the Child-OIDP inventory. Methods The Child-OIDP questionnaire was translated into Arabic was administered to a representative sample of 1109 schoolchildren in Khartoum state. Clinical measures employed in this study included DMFT index, Gingival index, Plaque index and Dean's index. A food frequency questionnaire was used to study the sugar-sweetened snack consumption. Results The instrument showed acceptable psychometric properties and is considered as a valid, reliable (Cronbach's alpha 0.73 and practical inventory for use in this population. An impact was reported by 54.6% of the schoolchildren. The highest impact was reported on eating (35.5% followed by cleaning (28.3% and the lowest impacts were on speaking (8.6% and social contact (8.7%. Problems which contributed to all eight impacts were toothache, sensitive teeth, exfoliating teeth, swollen gums and bad breath. Toothache was the most frequently associated cause of almost all impacts in both private and public school attendees. After adjusting for confounders in the 3 multiple variable regression models (whole sample, public and private school attendees, active caries maintained a significant association with the whole sample (OR 2.0 95% CI 1.4-2.6 and public school attendees (OR 3.5 95% CI 2.1-5.6, and higher SES was associated with only public school attendees' Child-OIDP (OR 1.9 95% 1.1-3.1.

Differentiation of preadipocyte, also called adipogenesis, leads to the phenotype of mature adipocyte. However, excessive adipogenesis is closely linked to the development of obesity. Artesunate, one of artemisinin-type sesquiterpene lactones from Artemisia annua L., is known for anti-malarial and anti-cancerous activities. In this study, we investigated the effect of artesunate on adipogenesis in 3T3-L1 preadipocytes. Artesunate strongly inhibited lipid accumulation and triglyceride (TG) synthesis during the differentiation of 3T3-L1 preadipocytes into adipocytes at 5 μM concentration. Artesunate at 5 μM also reduced not only the expressions of CCAAT/enhancer-binding protein-α (C/EBP-α), peroxisome proliferator-activated receptor-γ (PPAR-γ), fatty acid synthase (FAS), and perilipin A but also the phosphorylation levels of signal transducer and activator of transcription-3 (STAT-3) during adipocyte differentiation. Moreover, artesunate at 5 μM reduced leptin, but not adiponectin, mRNA expression during adipocyte differentiation. Taken together, these findings demonstrate that artesunate inhibits adipogenesis in 3T3-L1 preadipoytes through the reduced expression and/or phosphorylation levels of C/EBP-α, PPAR-γ, FAS, perilipin A, and STAT-3. -- Highlights: •Artesunate, an artemisinin derivative, inhibits adipogenesis. •Artesunate inhibits C/EBP-α, PPAR-γ, FAS, perilipin A, and STAT-3 in 3T3-L1 adipocytes. •Artesunate reduces leptin, but not adiponectin, expression in 3T3-L1 adipocytes. •Artesunate thus may have therapeutic potential against obesity.
Oral hygiene grade and quality of life in children with chemotherapy-related oral mucositis: a randomized study on the impact of a fluoride toothpaste with salivary enzymes, essential oils, proteins and colostrum extract versus a fluoride toothpaste without menthol.

The aim of this study was to assess the impact of the use of a fluoride toothpaste (Bioxtra ® , Biopharm, Milan, Italy) with salivary enzymes, essential oils, proteins and colostrum extract versus a fluoride toothpaste without menthol on the oral hygiene grade and on the quality of life (QoL) of children with oral mucositis (OM) grade 1 or 2 receiving chemotherapy for Acute Lymphoblastic Leukaemia (ALL). Patients between 6 and 14 years with OM were randomly assigned to two groups, group A (Bioxtra ® toothpaste) and group B (fluoride toothpaste without menthol). The patients were instructed to brush their teeth at least twice a day using a soft toothbrush with a small head. Oral hygiene grade was assessed using the simplified oral hygiene index (OHI-s); quality of life was assessed using the short form of the Oral Health Impact Profile (OHIP-14) questionnaires. The patients were evaluated on day 1(diagnosis of OM-T0) and on day 8 (T1). Statistical analysis was performed. A total of 64 patients were enrolled.

While the oral health-related quality of life (OHRQoL) is known to be reduced in patients with cleft lip and palate (CLP), its inter-dependency with the soft tissue characteristics of the CLP area remains unclear. This study aimed to evaluate the soft tissue characteristics in the treated cleft area in order to investigate whether gingival esthetics correlate with OHRQoL. Thirty-six patients with unilateral or bilateral CLP (46 cleft areas) were investigated after secondary/tertiary alveolar bone grafting and orthodontic/prosthetic implant treatment using an adapted score to rate gingival esthetics (clinical esthetic score, CES). The patient's OHRQoL was determined using the German short version of the Oral Health Impact Profile questionnaire (OHIP-G14). The results showed a significantly better rating in patients with their own teeth in situ (12.05±1.10) than in patients with implants (6.95±4.78) or prosthetics (4.00±3.58). The best OHRQoL values were achieved by patients with their own teeth integrated into the cleft area (1.32±2.31), followed by patients with implants (2.33±2.33) and prosthetics (3.75±5.87). A significant (P=0.017) correlation was found between OHIP-G14 and CES scores, suggesting an increased OHRQoL in cases with higher oral esthetics in the cleft area. The therapeutic strategy contributes to both gingival esthetics and OHRQoL. The patient's subjective perception of OHRQoL can be attributed to objective gingival esthetic ratings.

We studied the effect of metformin or placebo in a lifestyle modification program (LSM) combined with oral contraceptives (OC) on quality of life parameters measured by the PCOS questionnaire (PCOSQ) in obese adolescent women with validated PCOS. The quality of life indicators were measured at baseline and conclusion for 5 domains on the PCOSQ, with equal improvement in scores in both placebo and Metformin groups, suggesting metformin addition does not add improvement to quality of life measures above those observed with lifestyle modification and oral contraceptive treatment.

The aim of this study is to analyze the grades given for the oral/practical part of the German State Examination at the Medical Faculty of Freiburg. We examined whether or not the grades given for the written and the oral/practical examinations correlated and if differences in grading between the Freiburg University Medical Center (UMC) and the other teaching hospitals could be found. In order to improve the quality of the state examination, the medical school has been offering standardized training for examiners for several years. We evaluated whether or not trained and untrained examiners differed in their grading of the exam and how these differences have changed over time. The results of the 2012 spring and fall exams were analyzed (N=315). The relevant data set was made available to us by the Baden-Württemberg Examination Office (Landesprüfungsamt). The data were analyzed by means of descriptive and inferential statistics. We observed a correlation of ρ=0.460** between the grades for the written and the oral/practical exams. The UMC and the teaching hospitals did not differ significantly in their grade distributions. Compared to untrained examiners, trained ones assigned the grade of "very good" less often. Furthermore, they displayed a significantly higher variance in the grades given (p=0.007, phi=0.165). This effect is stronger when concentrating specifically on those examiners who took part in the training less than a year before. The results of this study suggest that the standardized training for examiners at the Medical Faculty of Freiburg is effective for quality assurance. As a consequence, more examiners should be motivated to take part in the training.

The objective of this study was to assess changes in the oral health-related quality of life (OHRQoL) among patients wearing fixed orthodontic appliances 24 h after insertion. Sixty patients aged between 14 and 24 years (29 males and 31 females; mean age, 17.8 years; SD 3.1 years) were recruited from the Postgraduate Clinic, Department of Children's Dentistry and Orthodontics, Faculty of Dentistry, University of Malaya. The oral health-related quality of life (OHRQoL) was measured before treatment and 24 h after insertion of the orthodontic appliance. The instrument used to measure OHRQoL was a modified self-administered short version of Malaysian Oral Health Impact Profile (OHIP-16[M]) questionnaire. The higher the score, the poorer is the OHRQoL. Overall score of OHRQoL increased significantly 24 h after insertion (mean 43.5±10.9) as compared to before insertion (mean 34.1±9.2) (Pbad breath, difficulties in pronunciation, discomfort in eating, ulcer, pain, avoidances of eating certain foods, difficulties in cleaning, embarrassment, avoid smiling, disturbed sleep, concentration affected, difficulty carrying out daily activities, and lack of self-confidence (P<0.05). Significant changes were also found in the mean difference of OHRQoL for gender (P<0.001). OHRQoL was found to deteriorate 24 h after insertion of fixed orthodontic appliances in almost all domains, with significant changes in gender. This information can be used as "informed consent", which might increase patient's compliance as they are aware of what to expect from initial orthodontic treatment.

The symptoms associated with burning mouth syndrome can be quite varied and can interfere with the every day lives of patients. Management of the condition can be challenging for clinicians. To determine the oral health-related quality of life (OHRQOL) implications of BMS on patients over a period of time whilst undergoing treatment and to evaluate whether treatment interventions had a positive effect on OHRQOL. Thirty-two individuals (26 females, 6 males, mean age 61 years, range 38-83 years) were enrolled in this study. Individuals were interviewed using Short-Form McGill Pain Questionnaire (SFMPQ), Visual Analogue Scale (VAS), the Hospital Anxiety and Depression Scale (HADS) and the Oral Health Impact Profile (OHIP-14), at weeks 0, 8 and 16. Scores from all outcome measures used decreased over the 16 weeks of the study. Statistically significant differences were found between time points for VAS pain scores (P < 0.001), HADS depression scores (P = 0.029), SFMPQ sensory pain scores (P < 0.01) and total scores for OHIP-14 (P < 0.05). Burning mouth syndrome has a negative impact on OHRQOL; however, individually tailored management of the condition can result in an improvement in patient-reported outcome measures including quality of life.

To assess the effect of removable partial dentures (PRD) restoration on oral health-related quality of life (OHRQOL) of subjects with shortened dental arches (SDA) using the Chinese version of the Oral Health Impact Profile (OHIP-14). Consecutive patients with shortened dental arches were recruited from the Department of Prosthodontics, Foshan Chancheng Hospital of Stomatology. The Chinese version of OHIP-14 was administered to each subject before treatment and after treatment. The subjective outcomes of removable partial dentures therapy on SDA were collected and the pre- and post-treatment scores of the Chinese version of OHIP-14 were compared. After treatment, significant decrease in patients' total score of OHRQOL [before: 9 (6, 12) ; after: 4 (2.25, 6)] was detected, as well as physical pain subscale, physical disability subscale and handicap subscale; and the score of OHRQOL in function limitation subscale increased [before: 0(0,0); after: 2(1, 2)]. The main impacts of shortened dental arch with intact anterior region affecting patients' OHRQOL are physical disability.From a quality-of-life perspective, patients with SDA can perceive benefits from RPD.

To evaluate the impact of chronic periodontal diseases (PDs and compare phases of nonsurgical periodontal therapy (NSPT on oral health-related quality of life (OHRQoL in patients attending a tertiary care center of eastern Nepal. Materials and Methods. Matched for socioeconomic status, participants were recruited in two groups: moderate-to-severe chronic periodontitis (n=24, 43±46 years and chronic gingivitis (n=25, 30±96 years. The treatment modalities were scaling and root surface debridement (RSD and supragingival scaling, respectively. The impact of periodontal disease treatment status was assessed by a self-reported questionnaire of Nepali Oral Health Impact Profile (OHIP-14 at baseline and 9–12 weeks after NSPT. Results. The median (IQR OHIP-14 total scores for PDs reduced from 7 (3–11 to 3 (1–7.5 after NSPT. Both groups showed a significant improvement on OHRQoL (p value < 0.001. The periodontitis group showed an increased median (IQR reduction of 52% (35.22–86.15 compared with the gingivitis group with 27% (0.00–50.00. The impact on orofacial pain, orofacial appearance, and psychosocial dimensions was observed, which improved after NSPT in both groups. Conclusion. PDs are directly associated with OHRQoL and treatment of the disease may enhance quality of life from a patient’s perspective. Scaling and RSD provided better influence on OHRQoL than supragingival scaling.

To determine the difference in oral health-related quality of life (OHRQoL) in patients who received mandibular 2-implant overdentures and conventional dentures in a pragmatic international study. In this prospective study, data were gathered from 203 edentulous patients (mean age, 68.8; SD: 10.4 years) at eight centres in North America, South America and Europe. The patients were provided with new mandibular conventional dentures or implant overdentures supported by 2 implants and ball attachments and opposed by conventional dentures. At baseline and at 6 months post-treatment, patients rated their oral health-related quality of life using the OHIP-20. A significantly higher proportion of the participants in the implant group in North America reported improvement in both the psychological and the handicap domains, compared to those who received conventional dentures (93% vs. 52%; P overdentures reported improvement in physical pain, compared to 66% in the conventional group (P overdentures are more likely than conventional dentures to improve OHRQL for edentulous patients. Cultural differences were also observed in the impact of implant overdentures on the different domains of the OHIP-20. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Plasmodium falciparum in Thailand is multi-drug resistant. In a previous study it was shown that artesunate and mefloquine were effective, as follow up, we monitored the efficacy of this regimen for six years. During 1997-2002, 516 adult male volunteer patients in Chanthaburi Province were enrolled (50 patients in the first year, 400 patients in 1998-2001 and 66 patients in 2002). The symptom complex and parasite count (thick blood film) were monitored on days 0, 1, 2, 7, 14, 21, 28, 35 and 42. The dosages used were artesunate (ATS) 150 mg and mefloquine (M) 750 mg at hour 0 and ATS 100 mg and M 500 mg at hour 24. Their ages ranged from 30-35 years and their mean body weights were 54-56 kg. The presenting symptoms were fever 100%, headache 97-100%, anorexia 78-90%, and nausea 28-40%. The geometric mean of parasitemia ranged from 7,357-12,750/mm3. Defervescence in one day was found in 42-76% of patients and 85-100% in 2 days. The sensitivity (S) ranged from 87-94% and RI resistance (recrudescence) ranged from 6-13%. Forty patients demonstrated RI type of response, 37 were cured after being retreated with the same dosage and another 3 patients were cured after the third course of treatment. The aggravated adverse effects included vomiting (8-20%), anorexia (1-41%) and diarrhea (0-16%). These side effects were mild and transient. The efficacy of the artesunate and mefloquine combination for the treatment of uncomplicated falciparum malaria was high. The RI type of response was possibly due to re-infection or multiple broods and not to drug resistance. The adverse effects of anorexia, nausea, vomiting and diarrhea were mild and transient for mefloquine. The combination can be used as stand by treatment in areas of multi-drug resistant falciparum malaria.

Purpose. To estimate the impact of the provision of dentures to Thai older people by the Royal Project on their oral health-related quality of life. Methods. A purposive cross-sectional study of a sample of 812 subjects was conducted. The Oral Impacts on Daily Performances (OIDP) measure was used to assess the oral health-related quality of life. Results. Four groups of older people with different tooth types were studied. 216 (26.6%) had natural teeth (NT). 189 (23.3%) had natural and replaced teeth (NRT). 167 (20.6%) had below the minimum number of teeth but had no dentures (Edent) and 240 were edentate with complete dentures provided by the Royal Project (ECD) (29.6%). Overall, 36.5% had at least one oral impact. Eating was the most affected oral impact. When compared to the group with natural teeth (NT), the Edent group was significantly more likely to report having impacts on eating OR = 6.5 (3.9-10.9), speaking clearly OR = 43.7 (12.7-15.07), emotional stability OR = 16.5 (6.0-45.6), and social contacts OR = 4.6 (2.2-9.5) (p < 0.001). Conclusion. Those who are edentulous are much more likely to have an oral impact on their daily performances than those provided dentures. Provision of dentures may lead to improvement of considerable oral impacts.

To assess the impact of children's dental health status (DHS) on their oral health-related quality of life (OHRQoL). Participants were 11- and 12-year-old children attending public schools in the Kuwait Capital Region. Children's DHS was evaluated by clinical examinations and presented using decayed, missed, filled teeth/surface (DMFT/dmft, DMFS/dmfs); restorative (RI), plaque (PI); and pulp, ulcers, fistula, abscess (PUFA) indices. Children's OHRQoL was assessed using Child's Perception Questionnaire 11-14 (CPQ11-14). Means (SD) and frequencies were used for data description. Different factors were analyzed as predictors of OHRQoL by logistic regression analysis. A total of 440 children aged 11-12 years (50.7 % females) participated in this cross-sectional study. Mean (SD) DMFT/dmft, RI, PI, and PUFA scores were 2.91(2.75), 0.21 (0.34), 3.59 (1.63), 0.31 (0.85), respectively. The mean total CPQ11-14 was 20.72 (16.81). Mean scores of oral-symptoms, functional-limitations, emotional and social well-being were 4.26 (3.32), 5.40 (4.92), 5.48 (6.15), and 5.33 (6.05), respectively. Children with more than four fillings were 95 % less likely to have had oral symptoms than those with no fillings. Children with a DMFT/dmft of 2-3 were 2.8 times more likely to have functional limitation than those with a DMFT/dmft of 0, while children with a DMFT/dmft of more than 4 were 4.4 times more likely to experience limitations. Having two or three non-cavitated lesions reduced the odds of having functional-limitation by 58 %. Children with more than four missing teeth were 45 % more likely to experience emotional stress. Having more than four fissure sealants reduced the odds of having emotional stress by 46 %. The increase in the number of carious teeth was associated with a limitation in oral functions. Preventive treatment had a positive impact on children's emotional well-being and restorative treatments improved their oral function.

The cancer has constituted a public health problem. It has been the second leading cause of death in Costa Rica and it is anticipated that cases and deaths will increase in the coming years. One of the main problems of cancer has been the development of resistance to chemotherapy, so many research are focused on the search for new drugs and synergistic activities. The National Cancer Institute through the Developmental Therapeutics Program has made screening lot of natural compounds and synthetic on 60 cell lines derived from human tumors. This screening is presented with practical limitations and without evaluation of synergism with chemotherapeutic drugs at clinically relevant concentrations. Antitumour activities of artesunate and steroidal compounds are identified on a model of type T lymphoblastic leukemia, through optimization of various procedures, in order to build a more practical test platform for screening and confirm anticancer activity by new compounds. Compounds were screened by assaying of sulforhodamine B. An assay was optimized with fluorochromes calcein and ethidium homodimer-1. A cell cycle assay was used to confirm antiproliferative and cytotoxic activity, respectively. Finally, the mechanisms of death were characterized in a basic way by a trial with annexin V/iodide of prospidium, using inhibitors of autophagy, apoptosis and necroptosis to assess vias which have been the most important in cell death. The observation has been that only the artesunate has presented important activity on the cell line, being autotumoral and cytotoxic type. Also, a synergistic effect has presented with doxorrubicina chemotherapy and has caused cycle arrest at the G1/S phase. The ethidium/calcein homodimer-1 assay and V/iodide annexin of prospidium have showed that compound and the drug used has caused necrotic and apoptotic populations that have increased of dependent dose manner. The results have suggested that both agents activate several cell death pathways

To assess whether oral health-related quality of life (OHRQoL) is associated with nutritional status in the institutionalised elderly population of Mysore. Malnutrition in the elderly has an evident impact on their general health and quality of life. Analysis of data of the Geriatric Oral Health Assessment Index (GOHAI) and their association with the Mini Nutritional Assessment (MNA) results improves our understanding of the complex relationship between oral health and malnutrition. The study was conducted among the institutionalised elderly population in Mysore city, Karnataka. Data on socio-demographic, oral health status were gathered. OHRQoL was evaluated using GOHAI, and malnutrition risk using MNA. Out of 141 elderly, 41.1% were men and 58.9% were women with mean age of 72.2 ±7.5 years. Mean GOHAI score was 47.03 ± 9.2, with 69.5% had low perception of oral health. Mean MNA score was 9.91 ± 2.4, 15.6% were malnourished, 52.5% were at risk of malnutrition and 31.9% were adequately nourished. A strong association was found between the mean GOHAI and MNA scores. Oral health-related quality of life was associated with nutritional deficit, and it requires a greater integration between dentistry and nutrition in the health promotion of older adults. © 2012 John Wiley & Sons A/S and The Gerodontology Society.

The purposes of the study were to investigate and evaluate the differences detected by the patients between the traditional orthognathic approach and the surgery-first one in terms of level of satisfaction and quality of life. A total of 30 patients who underwent orthognathic surgery for correction of malocclusions were selected and included in this study. Fifteen patients were treated with the conventional orthognathic surgery approach, and 15 patients with the surgery-first approach. Variables were assessed through the Orthognathic Quality of Life Questionnaire and the Oral Health Impact Profile questionnaire and analyzed with 2-way repeated-measures analysis of variance. The results showed significant differences in terms of the Orthognathic Quality of Life Questionnaire (P surgery in the surgery-first group and an initial worsening during orthodontic treatment in the traditional approach group followed by postoperative improvement. This study showed that the worsening of the facial profile during the traditional orthognathic surgery approach decompensation phase has a negative impact on the perception of patients' quality of life. Surgeons should consider the possibility of a surgery-first approach to prevent this occurrence. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc.

Full Text Available Introduction: Evaluating the quality of life allows a more accurate clinical control as well as the provision of prognostic information for specific groups. This study was designed to evaluate the quality of life of elderly diagnosed with oral squamous cell carcinoma submitted to combined modality therapy. Methods: This is a retrospective and observational study, with cross-sectional quantitative character. A total of 206 records of patients with head and neck cancer treated between April 2013 and October 2014 were analyzed. Eleven patients over six months of treatment completion were included in the study. The questionnaire of quality of life of the University of Washington (UW-QOL was applied. The data were collected regarding the social-demographic, clinical-pathological and therapeutic profiles, and the non-stimulated salivary flow was measured. Statistical analysis of quantitative data was performed by the Spearman nonlinear correlation, considering a confidence of 95%. Results: Chewing, saliva and speech showed the lowest scores (31.8; 42.3; 60.6, respectively. Statistically significant correlation was found between: shoulder and mood (r=0.787; swallowing and chewing (r=0.761; completion time of radiotherapy and recreation (r=0.659; activity and recreation (r=0.653; pain and swallowing (r=0.626; chewing and speech (r=0.607; age and speech (r=-0.617. Conclusions: Elderly with oral squamous cell carcinoma diagnosis sunmitted to combined modality therapy presented the areas related to chewing, saliva and speech as the most committed ones. Older individuals have greater impairment of speech, as well as those with longer completion of radiotherapy have better results related to the recreation area.

Aim: To investigate the possibility of whether a single 300 mg dose of ranitidine given orally 2-3 h before magnetic resonance cholangiopancreatography (MRCP) could reduce the signal from the stomach and duodenum, and thus increase the conspicuousness of the biliary tree. Materials and methods: Thirty-five volunteers (22 female, 13 male), (age range 21-50) were underwent MRCP in a double-blind, placebo-controlled, randomized, crossover trial on a Philips Intera 1.5 T machine using a phased array surface coil. Imaging was carried out in the coronal oblique plane. Six 40 mm sections were acquired at varying angles to delineate the biliary tree and pancreatic duct. The 70 examinations were blindly scored by three consultants experienced in cholangiography. Results: After ranitidine administration there was a significant decrease in signal from the stomach (mean = 17.7, p = 0.0005, CI 10, 25.3) and duodenum (mean = 18.4, p = 0.0005, 95%CI 9.6, 27.1) with a significant increase in conspicuousness of the distal common duct (mean = 7.7, p = 0.033, 95%CI 0.7, 14.7) and proximal common duct (mean = 8.7, p = 0.010 CI 2.2, 15.2). There were no adverse effects. Conclusion: Oral ranitidine is a cheap and effective agent to decrease signal from the upper gastrointestinal tract and to improve visibility of the biliary tree
Full Text Available Objectives: The purpose of this study was to evaluate the oral health-related quality of life of patients treated with implant-supported mandibular overdentures and to compare the attachment systems used.Material and Methods: Altogether 112 patients treated with implant-supported mandibular overdentures in 1985 - 2004 were invited to the follow-up; 58 of them attended and replied to the Oral Health Impact Profile (OHIP-14 -questionnaire. There were 48 overdentures with a bar connection and 10 with a ball connection, the total number of implants installed and still in use was 197. The mean follow-up time was 13.7 years. The associations between the OHIP-14 variables and the patient’s age, gender as well as the number of implants supporting the overdenture and the type of attachment used were assessed.Results: The results showed that patients with implant-supported mandibular overdentures were satisfied with their oral health-related quality of life (OHRQoL. Older patients were more satisfied than younger ones in both genders. Neither the implant connection type nor the number of supporting implants seemed to have a significant influence on the OHRQoL.Conclusions: Especially older patients with mandibular implant-supported overdentures were satisfied with their oral health-related quality of life. Attachment type or the number of supporting implants did not have a significant influence on the oral health-related quality of life.

Abstract Background It is increasingly recognized that the impact of disease on quality of life should be taken into account when assessing health status. It is likely that tooth loss, in most cases being a consequence of oral diseases, affects Oral Health-Related Quality of Life (OHRQoL). The aim of the present study is to systematically review the literature and to analyse the relationship between the number and location of missing teeth and oral health-related quality of life (OHRQoL). It was hypothesized that tooth loss is associated with an impairment of OHRQoL. Secondly, it was hypothesized that location and distribution of remaining teeth play an important role in this. Methods Relevant databases were searched for papers in English, published from 1990 to July 2009 following a broad search strategy. Relevant papers were selected by two independent readers using predefined exclusion criteria, firstly on the basis of abstracts, secondly by assessing full-text papers. Selected studies were grouped on the basis of OHRQoL instruments used and assessed for feasibility for quantitative synthesis. Comparable outcomes were subjected to meta-analysis; remaining outcomes were subjected to a qualitative synthesis only. Results From a total of 924 references, 35 were eligible for synthesis (inter-reader agreement abstracts κ = 0.84 ± 0.03; full-texts: κ = 0.68 ± 0.06). Meta-analysis was feasible for 10 studies reporting on 13 different samples, resulting in 6 separate analyses. All studies showed that tooth loss is associated with unfavourable OHRQoL scores, independent of study location and OHRQoL instrument used. Qualitative synthesis showed that all 9 studies investigating a possible relationship between number of occluding pairs of teeth present and OHRQoL reported significant positive correlations. Five studies presented separate data regarding OHRQoL and location of tooth loss (anterior tooth loss vs. posterior tooth loss). Four of these reported highest impact

The aim of this study was to investigate the oral health-related quality of life (OHRQoL) among subjects with typical, atypically positive, and atypically negative personality trait scores within the five basic dimensions of personality (neuroticism, extroversion, openness, agreeableness, and conscientiousness). A total of 235 subjects not seeking dental treatment were recruited from the families and acquaintances of dental students from the University of Salamanca. The 14-item Oral Health Impact Profile (OHIP-14) was used to capture the impact on their OHRQoL. The Neouroticism-Extroversion-Openness Personality Inventory Revised was applied to assess personality profiles. People were classified as having negatively atypical, typical, or positively atypical (PAP) personality, depending on whether the sum of the Z scores was 1, respectively. Pearson correlation, analysis of variance, and logistic regression test were used for the statistical analyses. The sample was comprised of highly educated adults (aged 18-80 years) with good oral health habits. PAP subjects suffered significantly more in the dimension of psychologic discomfort (0.6 ± 0.7) than did their counterparts (0.3 ± 0.6), but the global impact in OHRQoL was comparable. Personality was weakly correlated with OHIP-14. The perception of dental treatment needs was found to be the major predictor of the impact on OHRQoL, but the number of negatively atypical deviated personality traits and the agreeableness raw score also had an effect. The risk of perceiving an impact on OHRQoL is significantly higher in individuals perceiving treatment needs and increases proportionally to the number of negatively atypical personality traits.

To evaluate an individually tailored oral health educational programme on patient-reported outcome compared with a standard oral health educational programme, assess change over time and determine minimal important differences (MID) in change scores for two different oral health related quality of life (OHRQoL) instrument after non-surgical periodontal treatment (NSPT). In a randomized controlled trial evaluating two educational programmes, patients (n = 87) with chronic periodontitis completed a questionnaire at baseline and after 12 months. OHRQoL was assessed with the General Oral Health Assessment Index (GOHAI) and the UK oral health-related quality-of-life measure (OHQoL-UK). In addition, patients' global rating of oral health and socio-demographic variables were recorded. The MID was estimated with anchor-based and distributions-based methods. There were no differences between the two educational groups. The OHRQoL was significantly improved after treatment. The MID was approximately five for OHQoL-UK with a moderate ES, and three for GOHAI with a Small ES, and 46-50% of the patients showed improvements beyond the MID. Both oral health educational groups reported higher scores in OHRQoL after NSPT resulting in more positive well-being (OHQoL-UK) and less frequent oral problems (GOHAI). OHQoL-UK gave a greater effect size and mean change scores but both instruments were associated with the participants' self-rated change in oral health. The changes were meaningful for the patients supported by the estimated MID. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In a previous study, we observed that the concordance between patients' and caregivers' evaluation of oral health-related quality of life (OHRQoL) was low. The aim of this study was to use multilevel analysis to investigate the possible determinants of the low concordance, taking into account different patients' demographic and clinical variables, the financial system used by patients to pay for dental treatment, and the role of the different caregivers and clinics. The OHRQoL of patients was assessed both by the patients and by their caregivers, using the Oral Health Impact Profile (OHIP)-14. Data were collected in four clinics, and patients were evaluated by one of 27 caregivers. We tested eight multilevel models, using the difference (caregivers OHIP - patients OHIP) as the dependent variable. Data were complete for 432 patients. The mean difference was 4.4 (standard deviation = 8.2; higher scores indicated a higher impact on OHRQoL). The variance due to patients was partly explained by their age, gender, and number of teeth, with a greater OHIP difference for older vs. younger patients, for women than for men, and in patients with fewer teeth. Almost 30% of the variance was due to caregivers, while the effect of clinics was not significant. It is important to study the possible causes of the different judgments concerning patients' OHRQoL by patients and caregivers, in order to improve the patients' satisfaction with care.

To determine changes in oral health-related quality of life (OHRQoL) during fixed orthodontic appliance therapy in Chinese patients. Two-hundred fifty Chinese orthodontic patients completed six distinct intervals of the 14-item Oral Health Impact Profile (OHIP-14, Chinese version): before treatment (T0); after the placement of the fixed appliance at 1 week (T1), 1 month (T2), 3 months (T3), and 6 months (T4); and posttreatment (T5). The overall response rate was 88.8% (222 of 250). Significant differences of overall OHIP-14 scores could be found between any two time points (P .05) and between T3 and T4 (P > .05). Overall scores at T1 were significantly higher than the scores at the other intervals (P orthodontic appliance therapy did affect Chinese patients' OHRQoL. Patients were considerably compromised in terms of their overall OHRQoL until approximately 1 month after insertion. The severity of the compromised condition in terms of overall OHRQoL was greatest at 1 week with the reported impact on physical pain, psychological discomfort, and physical disability. Patients' OHRQoL was better after they completed the orthodontic treatment than before or during treatment.

This study aimed to assess the impact of parent reported sleep bruxism, trait anxiety and sociodemographic/socioeconomic features on quality of life related to oral health (OHRQoL) of children and their families. Healthy children aged 3-7 years, with (n=34) and without (n=32) bruxism were select for this study. Data was collected by applying the following instruments: The Early Childhood Oral Health Scale (B-ECOHIS) and Trait-anxiety Scale (TAS). The sociodemographic/socioeconomic characteristics were obtained by interviews with parents. Multiple logistic regression tests were performed to observe the influence of sociodemographic/socioeconomic characteristics, bruxism and trait-anxiety on the children's OHRQoL. No association between sleep bruxism and all evaluated sociodemographic/socioeconomic conditions, with exception of being the only child (p=0.029), were observed. Mean B-ECOHIS and TAS scores were different (pbruxism. Although an association between bruxism and OHRQoL (p=0.015) was observed, it was dropped (p=0.336; OR=1.77) in the logistic regression model. Trait anxiety was the variable responsible for the impact on the OHRQoL of children (p=0.012; OR=1.05). Our results indicated anxiety as the main factor that interfered in the OHRQoL of children with sleep bruxism.

This study aimed to evaluate the impact of dental caries treatment on oral health-related quality of life (OHRQoL) among schoolchildren and the responsiveness of the Child Perceptions Questionnaire (CPQ8-10 ) instrument. Brazilian schoolchildren, 8-10 yr of age, were randomly selected and assigned to two groups--dental caries treatment (DCT) and caries-free (CF)--according to their caries experience [decayed, missing, or filled primary teeth (dmft) and decayed, missing or filled secondary teeth (DMFT) values of ≥ 0]. The CPQ8-10 instrument was administered at baseline and at 4 wk of follow-up (i.e. 4 wk after completion of dental treatment). In the DCT group, increases in CPQ8-10 scores were observed between the baseline and follow-up results. However, longitudinal evaluation of the CF group demonstrated no statistically significant difference in CPQ8-10 scores. Responsiveness of the CPQ8-10 instrument (magnitude of change in CPQ8-10 scores) in the DCT group was greater (effect size >0.7) than in the CF group. The findings of this study show that dental caries treatment has an important impact on OHRQoL of children. The CPQ8-10 was considered an acceptable instrument for longitudinal measurement of changes in OHRQoL. © 2015 Eur J Oral Sci.

The objective of this cross-sectional study was to evaluate the effect of prosthetic status on the oral health-related quality of life (OHRQoL) of nursing home residents with or without dementia. The study was performed in 14 nursing homes across the federal state of Baden-Württemberg, Germany. All eligible participants were included, and general and medical information and information about their dental and prosthetic statuses were collected. The Geriatric Oral Health Assessment Index (GOHAI) was administered to evaluate OHRQoL. The Mini-Mental State Examination (MMSE) served to classify participants into living or not living with dementia according to the established cutoff value for dementia (MMSE health was also similar in both groups ( P >0.05). The number of teeth (odds ratio [OR]: 2.0), the type of prosthetic status (OR: 6.5), and denture-related treatment needs (OR: 2.4) were the major factors significantly affecting OHRQoL ( P nursing home residents is substantially compromised. Several prosthetic treatment needs for residents living with or without dementia were identified. Edentulism without tooth replacement and having <5 teeth resulted in an increased risk of substantially compromised OHRQoL. Further studies should be conducted to determine whether improvements in prosthetic status can increase OHRQoL.

The aim of this study was to compare changes in child oral health-related quality of life (COHRQoL) after treatment for early childhood caries (ECC) using two alternative treatment approaches. A randomized control trial with random allocation of parent/child dyads with ECC to test (minimum intervention) or control (standard care). Participating parents completed the Early Childhood Oral Health Impact Scale (ECOHIS) at baseline and follow-up. Changes in ECOHIS scores and extent of COHRQoL impacts between and within groups were tested using the chi-squared statistic for groups, Wilcoxon's rank-sum test, and matched-pairs signed-rank test. Two hundred and fifty-four children were randomized (test = 127; control = 127). At baseline, mean ECOHIS score 11.1, sd 8.2; mean age = 3.8 years, sd 0.90; mean dmft = 4.9, sd 4.0; and 59% male. After a mean interval of 11.4 months, 210 children were followed-up and returned a completed questionnaire (test = 111; control = 99). There was no significant difference in COHRQoL changes between test and control. For all the children combined, there were significantly fewer impacts at follow-up in the child and family domains and the total ECOHIS, Wilcoxon signed-rank test, p test and control in the extent of the improvement. © 2016 Australian Dental Association.

Background: To associate oral health related quality of life with dental anxiety and depression along with general health among people of Bhopal district, Madhya Pradesh. Materials & Methods: A cross sectional questionnaires based survey was conducted among the subjects of Bhopal district, Madhya Pradesh. The survey was carried among 101 subjects aging from 20-40 years. Subjects under investigation were belonging to various occupations. They were assigned a questionnaire. Questionnaire consisted of four parts, first part consists of socio-demographic data along with dental visiting habits, second part has OHqOL-questionnaire, third part has general health (sf-12) and fourth part has hospital anxiety and depression questionnaire. Questionnaire was used for assessment of OHqOL. It consists of 16 questions which takes into account both effect and impact of oral health on quality of life. Dental anxiety and depression was measured by Hospital Anxiety and Depression Scale. Each question was provided with four options and numbering ranging from 0-3. For general health consideration sf-12 v2 was being used, which calculates two values PCS and MCS giving result in percentage. Results: A large proportion of respondent perceived oral health as having an enhanced effect on their quality of life in all three aspects that is general health, social and psychological. This is in stark contrast to other studies, where only physical aspects of oral health were more frequently considered to have the greatest overall impact of life quality compared with items relating to social, psychological and general health aspects. Conclusion: Gender variations were not apparent in the study. Both genders were likely to perceive oral health as it is impacting strongly on their quality of life. No significant gender variations are seen. But both have specific oral health needs and are most likely to utilize dental services which may be the key in understanding oral health behavior, including

Bony reconstruction of jaw defects using the free fibular flap and dental rehabilitation mostly requires insertion of dental implants within the transferred fibula bone. The aim of this paper was to discuss results of the implant stability with data on the possible benefit for the patient's quality of life after such treatment. For clinical outcome of implants, we evaluated 26 patients with a total number of 94 dental implants after a follow-up period of 12 to 132 months. A group of 38 patients who underwent mandibular reconstruction with free fibular flap could be included in the life-quality study. Evaluation included 23 patients with and 15 patients without implant-borne restoration. The quality of life was assessed using the standard QLQ C-30 questionnaire and the H&N35 module of the European Organisation for Research and Treatment of Cancer (EORTC). Of implants, 94.7 % were stable at the time of investigation and could be used for prosthesis. Patients with dental implants reported improvement of life quality along with better scores in most function and symptom scales; however, only values for global health status (QL2), absence of dyspnea (DY) and absence of feeding tube (HNFE) were significantly better than in the control group. Dental implant insertion in fibula grafts along with implant-borne restoration is a proven concept and might lead to improved quality of life following ablative surgery of the jaw. The effect on the quality of life is not as predictable as on the implant stability. Patients with bony defects of the jaw require bony reconstruction. This allows further masticatory rehabilitation using dental implants and might lead to improved quality of life.

Dried leaf Artemisia annua (DLA) has shown efficacy against Plasmodium sp. in rodent studies and in small clinical trials. Rodent malaria also showed resiliency against the evolution of artemisinin drug resistance. This is a case report of a last resort treatment of patients with severe malaria who were responding neither to artemisinin combination therapy (ACT) nor i.v. artesunate. Of many patients treated with ACTs and i.v. artesunate during the 6 mon study period, 18 did not respond and were subsequently treated with DLA Artemisia annua. Patients were given a dose of 0.5g DLA per os, twice daily for 5d. Total adult delivered dose of artemisinin was 55mg. Dose was reduced for body weight under 30kg. Clinical symptoms, e.g. fever, coma etc., and parasite levels in thick blood smears were tracked. Patients were declared cured and released from hospital when parasites were microscopically undetectable and clinical symptoms fully subsided. All patients were previously treated with Coartem® provided through Santé Rurale (SANRU) and following the regimen prescribed by WHO. Of 18 ACT-resistant severe malaria cases compassionately treated with DLA, all fully recovered. Of the 18, this report details two pediatric cases. Successful treatment of all 18 ACT-resistant cases suggests that DLA should be rapidly incorporated into the antimalarial regimen for Africa and possibly wherever else ACT resistance has emerged.

Artemisinin- and artesunate-resistant Plasmodium chabaudi mutants, AS-ART and AS-ATN, were previously selected from chloroquine-resistant clones AS-30CQ and AS-15CQ respectively. Now, a genetic cross between AS-ART and the artemisinin-sensitive clone AJ has been analysed by Linkage Group Selection. A genetic linkage group on chromosome 2 was selected under artemisinin treatment. Within this locus, we identified two different mutations in a gene encoding a deubiquitinating enzyme. A distinct mutation occurred in each of the clones AS-30CQ and AS-ATN, relative to their respective progenitors in the AS lineage. The mutations occurred independently in different clones under drug selection with chloroquine (high concentration) or artesunate. Each mutation maps to a critical residue in a homologous human deubiquitinating protein structure. Although one mutation could theoretically account for the resistance of AS-ATN to artemisinin derivates, the other cannot account solely for the resistance of AS-ART, relative to the responses of its sensitive progenitor AS-30CQ. Two lines of Plasmodium falciparum with decreased susceptibility to artemisinin were also selected. Their drug-response phenotype was not genetically stable. No mutations in the UBP-1 gene encoding the P. falciparum orthologue of the deubiquitinating enzyme were observed. The possible significance of these mutations in parasite responses to chloroquine or artemisinin is discussed. PMID:17581118

Vitamin K antagonists, such as warfarin, are standard treatments for stroke prophylaxis in patients with atrial fibrillation. Patient outcomes depend on quality of warfarin management, which includes regular monitoring and dose adjustments. Recently, novel oral anticoagulants (NOACs) that do not require regular monitoring offer an alternative to warfarin. The aim of this study was to evaluate whether cost effectiveness of NOACs for stroke prevention in atrial fibrillation depends on the quality of warfarin control. We developed a Markov decision model to simulate warfarin treatment outcomes in relation to the quality of anticoagulation control, expressed as percentage of time in the therapeutic range (TTR). Standard treatment with adjusted-dose warfarin and improved anticoagulation control by genotype-guided dosing were compared with dabigatran, rivaroxaban, apixaban and edoxaban. The analysis was performed from the Slovenian healthcare payer perspective using 2014 costs. In the base case, the incremental cost-effectiveness ratio for apixaban, dabigatran and edoxaban was below the threshold of €25,000 per quality-adjusted life-years compared with adjusted-dose warfarin with a TTR of 60%. The probability that warfarin was a cost-effective option was around 1%. This percentage rises as the quality of anticoagulation control improves. At a TTR of 70%, warfarin was the preferred treatment in half the iterations. The cost effectiveness of NOACs for stroke prevention in patients with nonvalvular atrial fibrillation who are at increased risk for stroke is highly sensitive to warfarin anticoagulation control. NOACs are more likely to be cost-effective options in settings with poor warfarin management than in settings with better anticoagulation control, where they may not represent good value for money.

Many young paediatric patients with severe dental caries receive dental treatment under general anaesthesia. Oral health-related quality of life (OHRQoL) can be evaluated to assess the outcome of dental general anaesthesia (DGA) treatment. The aim of our study was to examine the OHRQoL of young Lithuanian children in need of DGA treatment and analyse the impact of DGA treatment on children's OHRQoL. We carried out a prospective clinical follow-up study on OHRQoL among all young Lithuanian child patients who received DGA treatment at the Lithuanian University of Health Sciences Hospital during 2010-2012. The study consisted of clinical dental examinations of patients younger than six years, data collected from their patient files, and an OHRQoL survey completed by their parents prior to the child's dental treatment. We conducted a follow-up OHRQoL survey one month after the DGA treatment. The Early Childhood Oral Health Impact Scale (ECOHIS) and its effect size (ES) served to evaluate children's OHRQoL, and the Wilcoxon signed-rank test served for statistical analyses. We obtained complete baseline and follow-up data for 140 and 122 participants, respectively (84.7% follow-up rate). Pain and eating problems among children and parents feeling upset and guilty were the most frequently reported impacts at baseline. The parents reported greater impacts on boys than on girls. The ECOHIS score decreased significantly (69.5%, p family (2.4) sections of the ECOHIS. The OHRQoL of young Lithuanian children requiring DGA treatment is seriously impaired. Dental general anaesthesia treatment results in significant improvement of the children's OHRQoL.

This work aims to confirm if implant-supported overdentures are a good treatment option for edentulous patients and offer an improvement in quality of life compared with traditional complete prostheses (dentures). This retrospective clinical descriptive study included three evaluation groups: validation group (n=57); control group of patients with complete removeable prostheses (n=56); study group of patients with implant-supported overdentures retained with the Locator® system (n=80). The study also validated the Oral Health Impact Profile-20 questionnaire. Individual protocols were created that included socio-demographic data, the Oral Health Impact Profile-20 (OHIP-20) questionnaire and Oral Satisfaction Scale (OSS). Descriptive and bivariate statistical analysis was carried out applying χ², Pearson, Kruskal-Wallis, and Student t tests, transferring data into SPSS-Windows® software from a Microsoft® Excel spreadsheet. The OHIP-20 proved to be a valid instrument and provided reliable assessment of health-related quality of life among both the Spanish general population and edentulous patients. The control and study groups proved comparable, showing socio-demographic homogeneity. For patients with overdentures retained by means of the Locator® system, these restorations had significantly lower impact on quality of life (19 vs 33), both generally and for each individual questionnaire item, and much higher satisfaction with the state of their oral cavities (8.3 vs 5.3) than patients wearing dentures; both sets of data showed a direct linear relationship, so that as the level of impact on quality of life increased, perceived oral satisfaction worsened. Patients rehabilitated with implant supported overdentures retained by the Locator® system, presented significantly lower levels of impact on their quality of life and significantly higher oral satisfaction than patients with conventional complete prostheses.

Long half life oral anticoagulants have shown a higher anticoagulation stability and a lower hemorragic risk than those of a short half life. We have compared therapeutic stability and hemorragic risk of acenocoumarol versus warfarin in 2 groups of patients on preventive anticoagulation because of atrial fibrilation (international normalised ratio [INR]: 2-3). Data on 120 patients treated with acenocoumarol and 120 on warfarin treatment who had started and continued treatment in our hospital for a minimum of a year was collected. The percentage of visits within the intended range of INR (2 to 3) was 65.5% with warfarin and 63.4% with acenocoumarol. Thirty percent of patients on warfarin had 75% or more of their controls within range, while for those treated with acenocoumarol this percentage was 22.5%. In the acenocoumarol group, 0.3 visits/patient/year presented an INR > or = 6 versus 0.07 in the warfarin group (p = 0.003). Patients treated with acenocoumarol show a higher risk of presenting with an INR > or = 6, but no statistically significant differences are observed in therapeutic stability.

This paper describes a rational method of characterizing the biopharmaceutical stability of two oral suspensions of ursodeoxycholic acid (UDCA) used in pediatrics. Because there is no commercial presentation of UDCA that can administer appropriate doses for infants and children, an active pharmaceutical ingredient (API) formulation is required. Due to its very low solubility and low dose in the formula (1.5%), two different suspensions with minimal use of excipients were studied, avoiding the use of complex additives and those not recommended by the European Medicines Agency (EMA). Adherence to Standard Operating Procedure (SOP) allows the preparation of formulations with appropriately sized and stable particles, and suitable rheological behavior in withdrawing the dose after stirring. Dose uniformity, expressed as mass and content variability, was determined using the criteria of the European and the United States Pharmacopoeia. Additionally, dose content variation of every mass determined was studied. A rational method was developed for determining the dose uniformity of UDCA in suspensions, whether freshly prepared or after storage under different conditions for 30 and 60 days. This method permits detection of differences between doses taken at different heights in the vessel at various times and storage conditions. UDCA was stable under all conditions studied, requiring the presence of glycerol in the formulation to obtain the declared API value after stirring. Storage of UDCA suspensions in a refrigerator increased variability between doses. Copyright © 2014 Elsevier B.V. All rights reserved.
Full Text Available Abstract Background Oral health-related quality of life can be assessed positively, by measuring satisfaction with mouth, or negatively, by measuring oral impact on the performance of daily activities. The study objective was to validate two complementary indicators, i.e., the OIDP (Oral Impacts on Daily Performances and Oral Satisfaction 0–10 Scale (OSS, in two qualitatively different socio-demographic samples of the Spanish adult population, and to analyse the factors affecting both perspectives of well-being. Methods A cross-sectional study was performed, recruiting a Validation Sample from randomly selected Health Centres in Granada (Spain, representing the general population (n = 253, and a Working Sample (n = 561 randomly selected from active Regional Government staff, i.e., representing the more privileged end of the socio-demographic spectrum of this reference population. All participants were examined according to WHO methodology and completed an in-person interview on their oral impacts and oral satisfaction using the OIDP and OSS 0–10 respectively. The reliability and validity of the two indicators were assessed. An alternative method of describing the causes of oral impacts is presented. Results The reliability coefficient (Cronbach's alpha of the OIDP was above the recommended 0.7 threshold in both Validation and Occupational samples (0.79 and 0.71 respectively. Test-retest analysis confirmed the external reliability of the OSS (Intraclass Correlation Coefficient, 0.89; p Conclusion OIDP and OSS are valid and reliable subjective measures of oral impacts and oral satisfaction, respectively, in an adult Spanish population. Exploring simultaneously these issues may provide useful insights into how satisfaction and impact on well-being are constructed.

Clinical oncology is still challenged by the development of drug resistance of tumors that result in poor prognosis for patients. There is an urgent necessity to understand the molecular mechanisms of resistance and to develop novel therapy strategies. Artesunate (ART) is an anti-malarial drug, which also exerts profound cytotoxic activity towards cancer cells. We first applied a gene-hunting approach using cluster and COMPARE analyses of microarray-based transcriptome-wide mRNA expression profiles. Among the genes identified by this approach were genes from diverse functional groups such as structural constituents of ribosomes (RPL6, RPL7, RPS12, RPS15A), kinases (CABC1, CCT2, RPL41), transcriptional and translational regulators (SFRS2, TUFM, ZBTB4), signal transducers (FLNA), control of cell growth and proliferation (RPS6), angiogenesis promoting factors (ITGB1), and others (SLC25A19, NCKAP1, BST1, DBH, FZD7, NACA, MTHFD2). Furthermore, we applied a candidate gene approach and tested the role of resistance mechanisms towards established anti-cancer drugs for ART resistance. By using transfected or knockout cell models we found that the tumor suppressor p16(INK4A) and the anti-oxidant protein, catalase, conferred resistance towards ART, while the oncogene HPV-E6 conferred sensitivity towards ART. The tumor suppressor p53 and its downstream protein, p21, as well as the anti-oxidant manganese-dependent superoxide dismutase did not affect cellular response to ART. In conclusion, our pharmacogenomic approach revealed that response of tumor cells towards ART is multi-factorial and is determined by gene expression associated with either ART sensitivity or resistance. At least some of the functional groups of genes (e.g. angiogenesis promoting factors, cell growth and proliferation-associated genes signal transducers and kinases) are also implicated in clinical responsiveness of tumors towards chemotherapy. It merits further investigation, whether ART is responsive in

The World Health Organization recommends the use of artemisinin-based combination therapies (ACTs) for the treatment of uncomplicated malaria. The two most widely adopted ACT regimens are artemether (AR)-lumefantrine (LR) (the combination is abbreviated AL) and amodiaquine (AQ)-artesunate (AS). Pharmacokinetic (PK) data informing the optimum dosing of these drug regimens is limited, especially in children. We evaluated PK parameters in Ugandan children aged 5 to 13 years with uncomplicated malaria treated with AL (n = 20) or AQ-AS (n = 21), with intensive venous sampling occurring at 0, 2, 4, 8, 24, and 120 h following administration of the last dose of 3-day regimens of AL (twice daily) or AQ-AS (once daily). AS achieved an estimated maximum concentration in plasma (Cmax) of 51 ng/ml and an area under the concentration-time curve from time zero to infinity (AUC0-∞) of 113 ng·h/ml; and its active metabolite, dihydroartemisinin (DHA), achieved a geometric mean Cmax of 473 ng/ml and an AUC0-∞ of 1,404 ng·h/ml. AR-DHA exhibited a Cmax of 34/119 ng/ml and an AUC0-∞ of 168/382 ng·h/ml, respectively. For LR, Cmax and AUC0-∞ were 6,757 ng/ml and 210 μg·h/ml, respectively. For AQ and its active metabolite, desethylamodiaquine (DEAQ), the Cmaxs were 5.2 ng/ml and 235 ng/ml, respectively, and the AUC0-∞s were 39.3 ng·h/ml and 148 μg·h/ml, respectively. Comparison of the findings of the present study to previously published data for adults suggests that the level of exposure to LR is lower in children than in adults and that the level of AQ-DEAQ exposure is similar in children and adults. For the artemisinin derivatives, differences between children and adults were variable and drug specific. The PK results generated for children must be considered to optimize the dosing strategies for these widely utilized ACT regimens. PMID:19841149

Aim: To evaluate the minimal iodine contrast medium load necessary for an optimal computed tomography colonography tagging quality. Materials and Methods: Faecal occult blood test positive patients were randomly selected for one of three iodine bowel preparations: (1) 3 x 50 ml meglumine ioxithalamate (45 g iodine), (2) 4 x 25 ml meglumine ioxithalamate (30 g iodine); or (3) 3 x 25 ml (22.5 g iodine) meglumine ioxithalamate. Two experienced readers assessed the tagging quality per colonic segment on a five-point scale and the presence of adherent stool. Also semi-automatic homogeneity measurements were performed. Patient acceptance was assessed with questionnaires. Results: Of 70 eligible patients, 45 patients participated (25 males, mean age 62 years). Each preparation group contained 15 patients. The quality of tagging was insufficient (score 1-2) in 0% of segments in group 1; 4% in group 2 (p < 0.01 versus group 1); and 5% in group 3 (p = 0.06 versus group 1). In group 1 in 11% of the segments adherent stool was present compared with 49% in group 2 and 41% in group 3 (p < 0.01, group 2 and 3 versus group 1). Homogeneity was 85, 102 (p < 0.01), and 91 SD HU (p = 0.26) in groups 1, 2, and 3, respectively. In group 1 two patients experienced no burden after contrast agent ingestion compared to one patient in group 2 and nine patients in group 3 (p = 0.017). Conclusion: A dose of 3 x 50 ml meglumine ioxithalamate is advisable for an optimal tagging quality despite beneficial effects on the patient acceptance in patients receiving a lower dose.

Full Text Available Introduction: Quality of life can be understood as the perception subjects have of their position in life in relation to their goals, expectations and concerns. Measuring and understanding the impact of oral health on the quality of life of people may contribute to the promotion of health and prevention of disease. The aim of this study was to evaluate the impact of oral health on the quality of life of young people in confinement. Methodology: Cross-sectional study with mixed approach. Adolescents between 14 and 18 years of age, confined in socio-educational juvenile detention centers in the Province of Córdoba, Argentina, were included in the study. After signing of informed consent, the OHIP-49 questionnaire was applied to 70 youngsters and 32 semi-structured interviews were conducted. Results: The OHIP-49 had a mean of 53.37±28.77, the dimensions with more impact were: functional limitation, physical pain and psychological discomfort. Confinement emerges as an amplifier of sensations and as a barrier for accessing palliative care. Regarding aesthetic aspects, subjects reported specific discomfort that does not always interfere with their self-esteem or relationship with peers. Conclusions: Young people perceive the impact of oral health on their quality of life from episodes of suffering, although not only because of pain, but also for aesthetic reasons. Confinement creates a particular context for sensations and resolutions on health-disease-care processes regarding oral health.

Male fertility can be evaluated through complete semen analysis. Plants belonging to the Tribulus genus are known for their role in enhancing sex hormone levels and semen quality. The aim of this study was to evaluate the effects of T. terrestris on semen quality and physiological parameters. Sixty-five men with abnormal semen evaluation were included in this study, in which they were prescribed with oral administration of Androsten ® (250 mg of Tribulus terrestris dried extract per capsule). Body fat percentage, lean muscle mass gain, fluctuation in steroid hormone levels and all semen parameters were analysed during the period of treatment. The results demonstrated that decrease in the percentage of body fat and increase in lean mass were significant, as well as increase in dihydrotestosterone levels. Complete semen analysis evaluated at the end of treatment showed significant enhancement in sperm concentration, motility and liquefaction time. Protodioscin, the main phytochemical agent of the Tribulus genus, acts on sertoli cells, germ cell proliferation and growth of seminiferous tubules. This component is known to convert testosterone into dihydrotestosterone, which plays important roles in male attributes. Our results indicate the therapeutic use of Tribulus terrestris by men presenting altered semen parameters, and/or undergoing infertility treatment. © 2016 Blackwell Verlag GmbH.

There is an increasing research interest in quality of life issues in orthodontics. In this study, we aimed to investigate changes in oral health related quality of life (OHRQoL) among adults during fixed orthodontic appliance therapy (FOAT). Two hundred thirty-two adult patients were enrolled from a consecutive sample at a university dental hospital. OHRQoL was assessed by 2 standardized instruments (OHIP-14 and OHQoL-UK) at 4 times: before treatment (T0), 6 months after bonding and banding (T1), 12 months after bonding and banding (T2), and 18 months after bonding and banding (T3). Friedman 2-way analysis of variance (ANOVA) and Wilcoxon signed rank tests were used to compare the relative changes of OHRQoL among the different time points. Significant changes in the summary scores of both the OHIP-14 and OHQoL-UK were observed during fixed orthodontic treatment (P orthodontic appliance therapy. In the early phase of treatment, the greatest deterioration in OHRQoL occurs. With ongoing treatment, the detrimental effects to OHRQoL are reduced.

Adherence to medications is an important factor that contributes to therapeutic success. With the current increase in the elderly population, information relating to adherence to treatment and quality of life (QoL) of diabetic elderly patients will help the healthcare provider to improve their treatment. Thus, this study aims to determine the factors affecting adherence to medications and the consequence of non adherence to QoL. This was a cross-sectional study using validated Morisky Medication Adherence Scale (MMAS) Questionnaire. This study was conducted to assess the level of adherence on oral hypoglycemic medications (OHM) and quality of life of the Type 2 diabetes mellitus (T2DM) elderly patients in an urban health centre in Malaysia. A retrospective medication record review was also conducted to collect and confirm data on patients' demographics, diagnosis, treatments, and outcomes. One hundred and seventy nine patients were recruited in this study. Median adherence score was 7.75 (IQR 6.50- 8.00). Good adherer was observed in 48.00% of the participants. A Chi-square test indicated significant correlation between adherence and HbA1c (p= 0.010). The mean elderly diabetes mellitus Problem Areas in Diabetes (PAID) score was 6.30 ±SD 8.50. A significant inversed association was observed between PAID score and the level of adherence (r = - 0.175, pwestern countries.

This paper evaluated the impact of cleft-related surgery on the oral health-related quality of life (OHRQoL) of youth with cleft over time. Data were derived from a 5-year, multi-center, prospective, longitudinal study of 1196 youth with cleft lip and/or palate and their caregivers. Eligible youth were between 7.5 and 18.5 years old, spoke English or Spanish, and were non-syndromic. During each observational period, which included baseline, and 1- and 2-year post-baseline follow-up visits, youths and their caregivers completed the Child Oral Health Impact Profile, a validated measure of OHRQoL. Multilevel mixed-effects models were used to analyze the effects of receipt of craniofacial surgery on OHRQoL over time. During the course of this study a total of 516 patients (43 %) received at least one surgery. Youth in the surgery recommendation group had lower self- (β = -2.18, p self- and proxy-rated OHRQoL at baseline. Both surgical and non-surgical youth (β = 3.73, p self-reported OHRQoL for youth postsurgery (β = 1.04, p self- and caregiver-rated OHRQoL when compared to non-surgical youth.

This study investigated the association between denture status [implant-supported fixed dentures (IDs) and removable partial dentures (RPDs)] and oral health-related quality of life (OHRQoL). Consecutive patients with IDs and RPDs were recruited from the Prosthodontics Departments at Showa University and Tokyo Medical and Dental University. The Japanese version of the Oral Health Impact Profile (OHIP-J-49) was administered to each subject. For each OHIP-J-49 question, the subjects were asked to indicate the frequency with which they had experienced a dental problem during the last month. Responses were recorded on a 5 point Likert rating scale, with 0 being never and 4, very often. Summary scores were calculated and regression analyses conducted to investigate the association between denture status and OHIP-J-49 summary score. In total 79 ID subjects (mean age±SD of 51.7±12.4 years, 44.3% men) and 109 RPD subjects (mean age of 66.5±8.6 years, 30% men) participated after giving informed consent. The regression analysis between the type of treatment and the OHIP-J-49 summary score revealed a significant association with a coefficient of 17.0 (Confidence interval, CI: 10.9-23.1). When age and duration of denture usage, which had significant associations with OHIP-J-49, were included in this model, the regression coefficient remained virtually unchanged at 17.4 (CI: 9.75-25.0), thus indicating little potential confounding by them. OHRQoL in patients with implant-supported fixed dentures is generally less impaired than it is in those patients with RPDs. © 2011 John Wiley & Sons A/S.

Full Text Available Aim: The study was designed to explore the changes in oral health-related quality of life (QoL in the immediate postoperative period following routine (non-surgical dental extraction. Setting and Design: A prospective study carried out at the Oral and Maxillofacial Surgery clinic of the Lagos University Teaching Hospital, Nigeria. Materials and Methods: Subjects attending who required non-surgical removal of one or two teeth under local anesthesia were included in the study. A baseline QoL questionnaire (oral health impact profile-14 [OHIP-14] was filled by each patient just before surgery, and only those who were considered to have their QoL "not affected" (total score 14 or less were included in the study. After the extraction, each subject was given a modified form of "health related QoL" [OHIP-14]-instrument to be completed by the 3 rd day-after surgery, and were given the opportunity to review the questionnaire on the 7 th day postoperative review. Results: Total OHIP-14 scores ranged between 14 and 48 (mean ± SD, 26.2 ± 8.3. Majority of the subjects (60% reported, "a little affected." Only few subjects (5.8% reported, "not at all affected," and about 32% reported, "quite a lot." Summation of OHIP-14 scores revealed that QoL was "affected" in 41 subjects (34.2% and "not affected" in 79 subjects (65.8%. More than 30% of subjects reported that their ability to chew, ability to open the mouth and enjoyment of food were affected following tooth extraction. Few subjects (14-34% reported deterioration in their speech and less than 20% of subjects reported that change in their appearance was "affected." Only few subjects (12.5-15.1% reported sleep and duty impairment.

To investigate the impact of periodontal status on oral health-related quality of life (OHRQoL) in patients with and without type 2 diabetes mellitus (T2DM). 61 patients with T2DM and 74 non-diabetic patients matched for age, gender and periodontal status (health, gingivitis, chronic periodontitis) were recruited. The oral health impact profile (OHIP)-49 was self-completed by all participants at baseline and by the patients with periodontitis at 3 months and 6 months after non-surgical periodontal therapy. There were no significant differences in the overall OHIP-49 summary scores between patients with T2DM (median; interquartile range; 37.0; 19.5-61.0) and without T2DM (30.4; 16.8-51.0) (p>0.05). Among non-diabetic patients, there were significantly higher OHIP-49 scores (indicating poorer OHRQoL) in patients with gingivitis (41.0; 19.7-75.7) and periodontitis (33.0; 19.9-52.5) compared to patients who were periodontally healthy (11.1; 7.1-34.5) (pdisability domains following periodontal treatment, indicating an improvement in OHRQoL. In contrast, there were no statistically significant changes in OHIP-49 scores following periodontal treatment in the patients with diabetes. T2DM does not impact on overall OHRQoL as measured by OHIP-49. Chronic periodontitis and gingivitis were associated with poorer OHRQoL in non-diabetic patients, with evidence of improvements following periodontal treatment, but no such effects were observed in patients with diabetes. Gingivitis and periodontitis are associated with reduced OHRQoL compared to periodontal health in non-diabetic patients, with improvements following treatment of periodontitis. No impact of type 2 diabetes on OHRQoL was noted; this may be related to the burden of chronic disease (diabetes) minimising the impact of oral health issues on OHRQoL. Copyright © 2015 Elsevier Ltd.

Abstract Background Recent research has suggested that chronic dry mouth affects the day-to-day lives of older people living in institutions. The condition has usually been considered to be a feature of old age, but recent work by our team produced the somewhat surprising finding that 10% of people in their early thirties are affected. This raises the issue of whether dry mouth is a trivial condition or a more substantial threat to quality of life among younger people. The objective of this s...
Published reports suggest that children with enamel defects, especially where enamel is missing or breaking down, experience considerable discomfort and are generally more fearful of dental treatment. However, children's oral health-related quality of life in relation to enamel defects has not been reported. The aim of this study was to examine the association between oral health-related quality of life among children (COHQoL) with enamel defects of the first permanent molars and deciduous caries experience. Children attending pre-primary schools in metropolitan Perth, Western Australia, were recruited and classified for enamel defects using the modified Developmental Defects of Enamel index. Caries experience of deciduous molars and canines was also recorded. Parents completed a child oral health-related quality of life questionnaire. Data were analysed using Kruskal-Wallis, Spearman's rank correlation, chi-square, multiple linear regression and ordered logistic regression to test the factors for their influence on the COHQoL. From the 550 children assessed (mean age 7.2 years) 522 COHQoL questionnaires were returned. Mean COHQoL score was 8.9 (sd 8.8). Bivariate tests showed no association of COHQoL with enamel defect status of the first permanent molars. COHQoL was associated with dmft (mean dmft 1.96, sd 2.62). Higher caries experience children had poorer reported oral health-related quality of life. The presence of enamel defects in the first permanent molars did not affect the children's oral health-related quality of life.
Full Text Available To date no comparative trials have been done, to our knowledge, of fixed-dose artemisinin combination therapies (ACTs for the treatment of Plasmodium falciparum malaria in pregnancy. Evidence on the safety and efficacy of ACTs in pregnancy is needed as these drugs are being used increasingly throughout the malaria-affected world. The objective of this study was to compare the efficacy, tolerability, and safety of artemether-lumefantrine, the most widely used fixed ACT, with 7 d artesunate monotherapy in the second and third trimesters of pregnancy.An open-label randomised controlled trial comparing directly observed treatment with artemether-lumefantrine 3 d (AL or artesunate monotherapy 7 d (AS7 was conducted in Karen women in the border area of northwestern Thailand who had uncomplicated P. falciparum malaria in the second and third trimesters of pregnancy. The primary endpoint was efficacy defined as the P. falciparum PCR-adjusted cure rates assessed at delivery or by day 42 if this occurred later than delivery, as estimated by Kaplan-Meier survival analysis. Infants were assessed at birth and followed until 1 y of life. Blood sampling was performed to characterise the pharmacokinetics of lumefantrine in pregnancy. Both regimens were very well tolerated. The cure rates (95% confidence interval for the intention to treat (ITT population were: AS7 89.2% (82.3%-96.1% and AL 82.0% (74.8%-89.3%, p = 0.054 (ITT; and AS7 89.7% (82.6%-96.8% and AL 81.2% (73.6%-88.8%, p = 0.031 (per-protocol population. One-third of the PCR-confirmed recrudescent cases occurred after 42 d of follow-up. Birth outcomes and infant (up to age 1 y outcomes did not differ significantly between the two groups. The pharmacokinetic study indicated that low concentrations of artemether and lumefantrine were the main contributors to the poor efficacy of AL.The current standard six-dose artemether-lumefantrine regimen was well tolerated and safe in pregnant Karen women with

To evaluate changes in the general and oral health-related quality of life (using the European Quality of Life indicator and the Oral Health Impact Profile-49 [OHIP-49], respectively) of patients treated with conventionally or immediately loaded implants. This clinical trial consisted of a clinical oral examination and a questionnaire-based interview carried out before and after both surgery and definitive prosthetic rehabilitation in a consecutive sample of patients requiring dental implants. According to the clinical diagnosis and patient preference, patients were assigned to the immediate loading group (IL group; n = 29) or the conventional loading group (CL group; n = 75). The change summary scores and effect sizes were calculated in the intermediate stage and at the final follow-up, taking baseline scores as reference. The oral health-related quality of life and oral satisfaction after implant therapy were significantly better than at baseline, with an even greater benefit when the implants were loaded immediately than when prosthetic rehabilitation was delayed. However, there were no significant differences in between-group comparisons in the ratings of general health status. The effect size for the OHIP-49 exceeded the threshold value of 0.8 for the domains functional limitation, pain/discomfort, and psychological discomfort in both groups and also for physical disability and psychological disability in the IL group. A gradual improvement in oral well-being scores, but not in those of general well-being, were observed for both groups from the intermediate stage to the final evaluation. This benefit was markedly greater for the IL group.

Full Text Available Background: The development and spread of antimalarial drug resistant parasites contributes to the global impact of the disease. In vivo efficacy assessments of treatments for Plasmodium falciparum malaria are essential for ensuring effective case management. Artemisinin-based combinations have been adopted as the first-line treatment for uncomplicated P. falciparum malaria in Cameroon since 2004. Methods: A total of 177 children aged six-months to 10 years with uncomplicated mono-infected falciparum malaria were randomized (1:1 to receive artesunate/sulphadoxine-pyrimethamine (AS/SP or artesunate/amodiaquine (AS/AQ pediatric tablets and followed up for 28 days according to the standard World Health Organization in vivo drug efficacy monitoring protocol. The primary and secondary endpoints were PCR uncorrected and corrected cure rates, as measured by adequate clinical and parasitological response (ACPR on day 28. Results: The PCR corrected cure rate was high, overall (88.1%, 95% CI 83.1–93.1, 85.9% (95% CI 78.2–93.6, and 90.2% (95% CI 83.8–96.6 for AS/SP and AS/AQ, respectively. Twenty-one treatment failures were observed during follow-up, constituting one (4.6%, 14 (8.2%, and six (3.5% early treatment failure (ETF, late clinical failure (LCF, and late parasitological failure (LPF, respectively. The drugs were well tolerated with no serious adverse events. Conclusions: Both AS/SP and AS/AQ are highly effective and well-tolerated treatments for uncomplicated P. falciparum malaria around the slope of Mount Cameroon.
Full Text Available Abstract Background The Child Perceptions Questionnaire (CPQ is a self-reported questionnaire developed to measure oral health-related quality of life in children. The CPQ aims to improve the description of children's oral health, while taking into consideration the importance of psychological aspects in the concept of health. The CPQ exists in two versions: the CPQ8–10 for children aged 8–10 years and the CPQ11–14 for those aged 11–14 years. The aim of this study was to develop a Danish version of the CPQ8–10 and the CPQ11–14 and to evaluate its validity for use among Danish-speaking children. Methods The instruments were translated from English into Danish in accordance with a recommended translation procedure. Afterwards, they were tested among children aged 8–10 (n = 120 and 11–14 years (n = 225. The validity was expressed by the correlation between overall CPQ scores and i self-reported assessment of the influence of oral conditions on everyday life (not at all, very little, some, a lot, very much and ii the self-reported rating of oral health. Furthermore, groups of children with assumed decreased oral health-related quality of life were compared with children with healthy oral conditions. Finally, we examined the internal consistency. Results The correlation between overall CPQ scores and global assessments of the influence of oral conditions on everyday life showed Spearman correlation coefficients of 0.45, P for CPQ8–10 and 0.50, P for CPQ11–14. The correlation between overall CPQ scores and the self-reported rating of oral health showed Spearman correlation coefficients of 0.45, P for CPQ8–10 and 0.17, P = 0.010 for CPQ11–14. The median overall CPQ8–10 scores were 7 for individuals with healthy oral conditions, 5 for individuals with cleft lip and palate, and 15 for individuals with rare oral diseases. The median overall CPQ11–14 scores were 9 for individuals with healthy oral conditions, 9 for individuals

Dental ailments like malocclusion affect not only the functional ability and aesthetic appearance of the person but also the psychological aspect of the individual. The aim of the present study was to the find relationship between quality of life and dental malocclusion among school going adolescents in Tamil Nadu, India. A cross-sectional study was conducted among 342 subjects of age range 14-19 years. Oral health status was assessed using WHO basic oral health survey (2013), orthodontic treatment needs according to Index of Orthodontic Treatment Needs (IOTN) and oral health quality of life using Oral Health Impact Profile-14 (OHIP-14). A total of 342 subjects were interviewed and examined. The mean DMFT score was 1.86±2.77. A 203 (59.4%) did not require any orthodontic treatment while 139 (40.6%) had orthodontic treatment need ranging from mild to very severe. It was seen that malocclusion affected some aspects of OHIP-14 significantly namely functional limitation, psychological discomfort and psychological disability. The comparison of OHIP-14 scores between treatment needed and treatment not needed was highly significant (p<0.001). Hence, it is stated that there is an urgent need to educate the school children and in turn their parents regarding the malocclusion for its treatment to prevent any effect on quality of life of the young adults.

Patients and Methods: This longitudinal study prospectively evaluates quality of life in two groups consisting of 53 neoadjuvant and primarily surgically treated patients with oral cancer, using the quality-of-life core questionnaire (QLQ-C30) and the head and neck cancer module (H and N 35) of the European Organization for Research and Treatment of Cancer (EORTC). Results: Postoperatively both groups showed a marked reduction in quality of life. 1 year later quality of life had equalized between the two groups to such an extent that the quality of life scores had almost reached the preoperative level. Both groups showed specific impairments in the symptom scales. In the neoadjuvant therapy group however, global health and the emotional status were reduced to a greater degree than in the other group. Conclusion: Temporary limitations in quality of life can be expected after tumor treatment of oral cancer as presented here. Neoadjuvant therapy concept is more aggressive and might result in a longer disease-free survival, but the restriction in quality of life is more severe. Primary goal is the eradication of the tumor. Nevertheless preservation or reconstruction of a maximum of function is essential for a high level of quality of life. (orig.) [de

Oral cancer patients from lower socio-economic backgrounds have worse outcomes of survival and health related quality of life. The mechanism of cause is not fully understood. The purpose of the paper is to report treatment selection, survival, health related quality of life, cause and place of death in relation to deprivation status. 553 patients treated for oral cancer between 2008 and 2012 were identified from records at University hospital. Mortality was tracked via the Office of National Statistics (ONS) and health-related quality of life was measured using the University Washington quality of life questionnaire (UW-QoLv4). Postcodes of residence at diagnosis were used to obtain index of multiple deprivation (IMD) 2010 scores. Nearly half of the sample (47%) lived in the 'most deprived' IMD 2010 quartile of residential areas in England and such patients when treated with curative intent using surgery with or without adjuvant radiotherapy had worse survival than patients living elsewhere, p=0.01 after adjusting for pathological staging and age group. There were no notable differences by IMD group in cancer being mentioned anywhere in part 1 or part 2 of the death certificate or in place of death. After adjustment for patient and clinical factors patients residing in more deprived areas had worse quality of life outcomes in regard to social-emotional functioning and overall quality of life but not in regard to physical oral function. Addressing inequalities in health care related to deprivation is a priority for patients with oral cancer. Copyright © 2015 Elsevier Ltd. All rights reserved.

Child oral health-related quality of life (COHRQoL) has been increasingly assessed; however, few studies appraised the influence of socioeconomic status on COHRQoL in developing countries. This study assessed the relationship of COHRQoL with socioeconomic backgrounds and clinical factors. This study followed a cross-sectional design, with a multistage random sample of 792 schoolchildren aged 12 years, representative of Santa Maria, a southern city in Brazil. Participants completed the Brazilian version of the Child Perceptions Questionnaire (CPQ(11-14)), their parents or guardians answered questions on socioeconomic status, and a dental examination provided information on the prevalence of caries, dental trauma and occlusion. The assessment of association used hierarchically adjusted Poisson regression models. Higher impacts on COHRQoL were observed for children presenting with untreated dental caries (RR 1.20; 95% CI 1.07-1.35) and maxillary overjet (RR 1.19; 95% CI 1.02-1.40). Socioeconomic factors also associated with COHRQoL; poorer scores were reported by children whose mothers have not completed primary education (RR 1.30; 95% CI 1.17-1.44) and those with lower household income (RR 1.13; 95% CI 1.02-1.26). Poor socioeconomic standings and poor dental status have a negative impact on COHRQoL; reducing health inequalities may demand dental programmes and policies targeting deprived population.

To evaluate preadolescent oral health related quality of life (OHRQoL) during the first month of fixed orthodontic appliance therapy. Descriptive study. The Department of Pediatric Dentistry and Orthodontics at Federal University of Minas Gerais, Belo Horizonte, Brazil. This study included a sample of 96 preadolescent children aged between 11 and 12 years undergoing orthodontic treatment with a fixed appliance. Preadolescent children were required to answer the short form of the Brazilian version of the Child Perceptions Questionnaire (CPQ11-14) before treatment (T0) and 1 month after placement of the fixed appliance (T1). Statistical analysis was performed using the Wilcoxon signed rank test and the Bonferroni correction for the domains of CPQ11-14. Out of the 96 patients originally admitted, one gave up the treatment before the placement of bands and one failed to return the second questionnaire (T1). So, a sample of 94 preadolescents participated in this study, with a response rate of 97·9%. Among the 94 participants, 49 were females (52·1 %) and 45 were males (47·9 %). The mean age was 11·5 years (SD = 0·502). There was a statistically significant improvement in emotional well-being domain (P0·013) before treatment and 1 month after the placement of fixed appliance. One month after the placement of fixed orthodontic appliance, the preadolescents had positive alterations in their OHRQoL mainly in the emotional well-being domain.

Nowadays, digital radiography is widely used in dental practice. One of the most common types is Photo Stimulated Phosphor Plate (PSP). The aims of this experimental study were to evaluate the impacts of different combinations of storage conditions and varying delays in reading of digital images captured using PSPs. Standardized images of a step wedges were obtained using PSPs from the Digora digital systems. Plates were exposed and immediately scanned to produce the baseline gold standard. The plates were re-exposed and stored in four different storage conditions: white light, yellow light, natural light environment and dark room, then scanned after 10 and 30 minutes and 4 and 8 hours. Objective analysis was conducted by density measurements and the data were analyzed statistically using GEE test. Subjective analysis was performed by two oral and maxillofacial radiologists and the results were analyzed using McNemar's test. The results from GEE analysis show that in the natural light environment, the densities in 10 minutes did not differ from the baseline. The mean densities decreased significantly during the time in all environments. The mean densities in step 2 for the dark room environment decreased with a slighter slope in comparison to yellow environment significantly. PSP images showed significant decrease in the density in plates scanned for 10 minutes or longer after exposure which may not be detected clinically. The yellow light environment had a different impact on the quality of PSP images. The spatial resolution did not change significantly with time.

In Nigeria about 50% of oral contraceptive pill users obtain their products from proprietary patent medicine vendors (PPMVs). This group of service providers are poorly trained and have very limited knowledge about contraception. This paper investigated the nature of the advice offered to simulated current and potential users of oral contraceptive pills. The main objective was to assess the nature and quality of advice provided by PPMVs to pill users. This study is based on findings from a 'mystery client' approach in which three scenarios related to contraceptive pill use were simulated. Each of the 12 mystery clients simulated one of the following three scenarios: new pill users (new to family planning or switching from condom to pills); user seeking a resupply of pills; and dissatisfied pill users intending to discontinue use. Simple random sampling was used to select 410 PPMVs from a total of 1,826 in four states in Nigeria. Qualitative study using in-depth interviews was also conducted. A majority of the PPMVs had pills in stock on the day of the survey and resupplied pills to the clients. PPMVs also understood the reason and importance of referring clients who were new adopters of oral contraceptive methods to a health facility; 30% of the PPMVs referred new adopters to a health facility. However, demand from clients who do not want to go to health care facilities (for various reasons) necessitated the provision of oral contraceptive pills to 41% of the first time users. Some PPMVs prescribed treatment to mystery clients who presented with perceived complications arising from the use of pills, while 49% were referred to a health facility. The advice given by PPMVs often falls short of safety guidelines related to the use of oral contraceptive pills. There is a need to continuously update knowledge among the PPMVs to ensure that they provide quality oral contraceptive services as PPMVs bridge the gap between medical experts and users in rural communities.

Aim: The aim of this study is to compare the effect of dental rehabilitation on oral health-related quality-of-life (OHRQoL) in children with special health care needs (CSHCN) and healthy children. Materials and methods: The prospective study's sample consisted of 213 parents of caries-affected children, who were aged 6 years or younger and were scheduled for dental rehabilitation under general anesthesia (DRGA). The parent-child dyads were recruited from three public hospitals in Jeddah between October 2014 and May 2016. They comprised healthy children (n = 133) and CSHCN (n = 80). Parents self-completed the early childhood oral health impact scale (ECOHIS) before and 1 month after DRGA. The parents also rated the overall oral health status of their children by answering a global question before and after DRGA. Results: At baseline, the CSHCN had significantly worse OHRQoL in most of the scale domains at 25.9 [standard deviation (SD) 11.3] and 19.9 (SD 10.3) respectively. The OHRQoL significantly improved in both groups postoperatively (p = 0.005, Wilcoxon rank-sum test). The effect size of the improvement in the CSHCN group (+1.8) was greater than that in the healthy group (+1.5) in all domains, except for the family impact and parental distress sections. Conclusion: The DRGA markedly improves OHRQoL in children aged 6 years or younger, and the improvement is even greater in CSHCN. Clinical significance: The substantial improvement in OHRQoL after DRGA highlights the importance of oral health care in young children, which should receive higher priority than it has been done to date. Keywords: Children with special health care needs, Dental caries, Early childhood oral health impact scale, General anesthesia, Oral health-related quality-of-life.

Objectives: To examine whether patients who report orofacial pain (OP) and temporomandibular disorders (TMD) have a poorer perception of their oral health-related quality of life and, if so, to what extent, and to analyze the association between oral health perception, sociodemographic variables and reported pain duration. Study Design: 407 patients treated at the OP and TMD units in the Healthcare District of Cordoba, Spain, diagnosed following the standard criteria accepted by the scientific community – the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) – were administered the Spanish version of the Oral Health Impact Profile questionnaire (OHIP-14). Bivariate and logistic regression analyses were performed to determine the degree of association between the patients’ OHIP-14 score and pain duration, pain intensity, and various sociodemographic variables. Results: The observed distribution was 89.4% women and 10.6% men. The mean OHIP-14 score was 20.57 ± 10.73 (mean ± standard deviation). A significant association (ppain grade, self-perceived oral health status and pain duration. Conclusions: The analysis of self-perceived oral health status in patients with OP and TMD, as measured by the OHIP-14, showed that oral health is perceived more negatively by women. Moreover, a one-point increase in the Chronic Pain Grade indicator increases the OHIP-14 indicator by 4.6 points, while chronic pain, defined as pain suffered by patients for one year or more, increases the OHIP-14 indicator by 3.2 points.

To compare the oral health-related quality of life of patients treated for cleft lip and/or cleft palate (CL/P) versus unaffected children between 8 and 15 years of age using a Spanish-language version of the Child Oral Health Impact Profile (COHIP-Sp) administered to a Chilean population. A cross-sectional study with a matched case-control design was used. Participants were 48 children (mean age 11.3 years) with a history of CL/P from three cities in Chile and one group of 96 children (mean age 11.2 years) unaffected by CL/P. The COHIP-Sp was applied to both groups. Quality of life was compared according to the overall score and the average score of items and domains on the COHIP-Sp scale between the two groups (Mann-Whitney U test; P self-image" (P = .0002). The oral health-related quality of life of children with a history of CL/P was similar to that of the control group. Nevertheless, a lower quality of life was observed concerning items associated with speech and being understood by other people. Further study into the risk factors associated with surgery and rehabilitative treatment is recommended.

A questionnaire designed to measure oral health-related quality of life (OHRQOL) in adults and children was assessed for its factorial structure and reliability using data from the Second International Collaborative Study on Oral Health Outcomes in New Zealand, Poland and Germany. Principal component analysis with orthogonal and oblique rotation was applied. The three-factor structure hypothesized for the children's questionnaire (self-reported oral disease symptoms, perceived oral well-being, social and physical functioning) was confirmed in New Zealand and Poland, and two self-reported oral disease symptom dimensions emerged in Germany. Five factors instead of the three hypothesized were identified for adults: two dimensions of symptoms were identified, and social and physical functioning appeared to be independent dimensions of OHRQOL. Similarity between the factors was demonstrated in all three countries. The reliability of the questionnaire ranged from moderate to excellent depending on the dimension and the country. These findings provide preliminary evidence of the cross-cultural stability of the OHRQOL questionnaire in New Zealand, Poland and Germany, for both children and adults. Further investigations by the present authors of the properties of the instrument in other samples will focus on demonstrating the stability and replicability of the factor structure identified here.
Full Text Available Background. The incidence of oral squamous cell carcinoma (OSCC is in the top 10 of all cancer entities. Regular oral examinations by dentists play an important role in oral cancer prevention. Methods. Patients with OSCC (n=1,607 and physicians (n=1,489 completed questionnaires during the DÖSAK Rehab Study. The psychosocial and functional factors collected in these questionnaires were assessed in the present study. We compared patients who visited their dentist at least once a year (group A with those who visited their dentist less than once a year (group B. Results. Patients in group A had significantly better health-related quality of life after tumor treatment than patients in group B. Patients in group A also had a smaller tumor size and less lymph node metastasis and lost fewer teeth during the treatment. This resulted in better prosthetic rehabilitation and better psychological status after tumor treatment. Conclusions. Dentists play an important role in the early recognition of oral cancer. This study should encourage dentists to take a more active role in oral cancer prevention.

To investigate the impact of socioeconomic status (SES) on the oral health-related quality of life (OHRQoL) among Syrian children with cleft lip, or palate, or both (CL/P). A cross-sectional study was carried out at the Pediatric Dentistry Department, Damascus University, Damascus, Syria from April 2010 to May 2011. After excluding subjects with mental disorders, dumb and/or deaf, as well, 87 cleft-children have completed the Arabic version of the Child Oral Health-Related Quality of Life Questionnaire (COHRQoL, 36-item) that was divided into 4 different domains (Oral Symptoms, Functional Limitations, Emotional Well-Being, Social Well-Being). The SES was measured by 5 questions, and based on those questions, it was divided into 3 categories (high, moderate, low). The chi square test, and ANOVA test were used to perform statistical analysis. Overall, the 4 COHRQoL domains, and each Oral Symptoms, Emotional Well-Being, and Social Well-Being domain separately showed significant differences between cleft-children in different SES levels (p<0.05). Children that belonged to a low level of SES were more worried than the others, and they also have lost more school lessons, and avoided social activities. We found that the decrease of SES can affect negatively the OHRQoL among children with CL/P. Low SES cleft-children may require special psychological and social support.

To determine the applicability of SWOT analysis for measuring the quality of public oral health services from the adult client's perspective. Data were collected using a structured questionnaire developed in an earlier study. The study group consisted of all adult (over 18 years of age) clients (n = 256) using public municipal oral health services in Kirkkonummi, Finland, during 2 weeks in 1995. Before treatment, patients filled out a questionnaire that measured the importance of their expectations in different aspects of oral care. After the appointment, they filled out a similar questionnaire that measured the enactment of these expectations in the treatment situation. The response rate was 51%. The difference between subjective importance and enactment of expectations was tested by Wilcoxon's signed rank test. Results were interpreted using both a conventional analysis of "expectation enacted or not" and SWOT analysis, which is used in strategic planning to identify areas of strengths (S), weaknesses (W), opportunities (O) and threats (T) in an organisation. In 28 statements out of 35, the two analyses revealed similar interpretations. In most areas the patient-perceived quality of the services was good. Weaknesses were found in the following areas: communicating to patients the causes and risk of developing oral diseases, informing them about different treatment possibilities, and including patients in decision-making when choosing restorative materials. SWOT analysis provided more structured interpretation of the results, and can be more easily transferred to development of services.

Aim: The study was designed to explore the changes in oral health-related quality of life (QoL) in the immediate postoperative period following routine (non-surgical) dental extraction. Setting and Design: A prospective study carried out at the Oral and Maxillofacial Surgery clinic of the Lagos University Teaching Hospital, Nigeria. Materials and Methods: Subjects attending who required non-surgical removal of one or two teeth under local anesthesia were included in the study. A baseline QoL questionnaire (oral health impact profile-14 [OHIP-14]) was filled by each patient just before surgery, and only those who were considered to have their QoL “not affected” (total score 14 or less) were included in the study. After the extraction, each subject was given a modified form of “health related QoL” [OHIP-14]-instrument to be completed by the 3rd day-after surgery, and were given the opportunity to review the questionnaire on the 7th day postoperative review. Results: Total OHIP-14 scores ranged between 14 and 48 (mean ± SD, 26.2 ± 8.3). Majority of the subjects (60%) reported, “a little affected.” Only few subjects (5.8%) reported, “not at all affected,” and about 32% reported, “quite a lot.” Summation of OHIP-14 scores revealed that QoL was “affected” in 41 subjects (34.2%) and “not affected” in 79 subjects (65.8%). More than 30% of subjects reported that their ability to chew, ability to open the mouth and enjoyment of food were affected following tooth extraction. Few subjects (14-34%) reported deterioration in their speech and less than 20% of subjects reported that change in their appearance was “affected.” Only few subjects (12.5-15.1%) reported sleep and duty impairment. Thirty-percent of subjects reported their inability to keep social activities, and 41% were not able to continue with their favorite sports and hobbies. Multiple regression analysis revealed no significant association between age, sex, indications for

This group of service providers are poorly trained and have very limited knowledge about contraception. This paper investigated the nature of the advice offered to simulated current and potential users of oral contraceptive pills. The main objective was to assess the nature and quality of advice provided by PPMVs to pill users. Method: This study is based on findings from a 'mystery client' approach in which three scenarios related to contraceptive pill use were simulated. Each of the 12 mystery clients simulated one of the following three scenarios: new pill users (new to family planning or switching from condom to pills; user seeking a resupply of pills; and dissatisfied pill users intending to discontinue use. Simple random sampling was used to select 410 PPMVs from a total of 1,826 in four states in Nigeria. Qualitative study using in-depth interviews was also conducted. Results: A majority of the PPMVs had pills in stock on the day of the survey and resupplied pills to the clients. PPMVs also understood the reason and importance of referring clients who were new adopters of oral contraceptive methods to a health facility; 30% of the PPMVs referred new adopters to a health facility. However, demand from clients who do not want to go

This cross over study aimed to evaluate the effect of telescopic distal extension removable partial dentures on oral health related quality of life and maximum bite force MATERIALS AND METHODS: Twenty patients with complete maxillary edentulism and partially edentulous mandibles with anterior teeth only remaining were selected for this cross over study. All patients received complete maxillary dentures and mandibular partial removable dental prosthesis (PRDP, control). After 3 months of adaptation, PRDP was replaced with conventional telescopic partial dentures (TPD) or telescopic partial dentures with cantilevered extensions (TCPD) in a quasi-random method. Oral health related quality of life (OHRQoL) was measured using OHIP-14 questionnaire and Maximum bite force (MBF) was measured using a bite force transducer. Measurements were performed 3 months after using each of the following prostheses; PRDP, TPD, and TCPD. TCPD showed the OHIP-14 lowest scores (i.e., the highest patient satisfaction with their OHRQoL), followed by TPD, and PRDP showed the highest OHIP-14 scores (i.e., the lowest patient satisfaction with OHRQoL). TCPD showed the highest MBF (70.7 ± 3.71), followed by TPD (57.4 ± 3.43) and the lowest MBF (40.2 ± 2.20) was noted with PRDP. WITHIN The Limitations of This Study, Mandibular Telescopic Distal Extension Removable Partial Dentures with Cantilevered Extensions Were Associated with Improved Oral Health Related Quality of Life and Maximum Bite Force Compared to Telescopic or Conventional PRDP. Telescopic distal extension removable prostheses is an esthetic restoration in partially edentulous patients with free end saddle. This article describes the addition of cantilevered extensions of this prosthesis. The results showed that telescopic distal extension removable prostheses with cantilevered extensions were associated with improved oral health related quality of life and maximum bite force compared to telescopic or conventional RPDs
One hundred consecutive referral letters, sent by dental practitioners to the Department of Oral and Maxillofacial Surgery, Dublin Dental School and Hospital, were audited in terms of quality. The audit was based on the Scottish Intercollegiate Guidelines Network (SIGN) recommendations of 1998. The audit demonstrated that in general referral letters required modification and did not give the clinician the required information. This paper sets out the results of the audit and suggests a template that should be used for future referrals.

Peri-implant tissue health is a requisite for success of dental implant therapy. Plaque accumulation leads to initiation of gingivitis around natural teeth and peri-implantitis around dental implants. Peri-implantitis around dental implants may result in implant placement failure. For obtaining long-term success, timely assessment of dental implant site is mandatory. To assess and evaluate Quality of Life (OHRQoL) of individuals with dental implants using the Oral Health Impact Profile (OHIP-14). Total 92 patients were evaluated for assessment of the health of peri-implant tissues by recording, Plaque Index (PI), Probing Pocket Depth (PD), Bleeding On Probing (BOP) and Probing Attachment Level (PAL) as compared to contra-lateral natural teeth (control). In the same patients Quality of Life Assessment was done by utilizing Oral Health Impact Profile Index (OHIP-14). The mean plaque index around natural teeth was more compared to implants and it was statistically significant. Other three dimensions mean bleeding on probing; mean probing attachment level and mean pocket depth around both natural teeth and implant surfaces was found to be not statistically significant. OHIP-14 revealed that patients with dental implants were satisfied with their Oral Health-Related Quality of Life (OHRQoL). Similar inflammatory conditions are present around both natural teeth and implant prostheses as suggested by results of mean plaque index, mean bleeding on probing, mean pocket depth and mean probing attachment level, hence reinforcing the periodontal health maintenance both prior to and after incorporation of dental implants. Influence of implant prostheses on patient's oral health related quality of life (as depicted by OHIP-14) and patients' perceptions and expectations may guide the clinician in providing the best implant services.

The aim of the present study was to investigate the effect of dental caries experience and the components of the decayed, missing and filled teeth (DMFT) index on oral health-related quality of life (OHRQoL) among adolescents in southern Brazil. A cross-sectional study was conducted with 509 adolescents aged 11-14 years enrolled at public schools in the municipality of Osório (southern Brazil). A calibrated examiner performed the clinical examination for caries (World Health Organization: DMFT index), malocclusion (Dental Aesthetic Index) and traumatic dental injuries [Andreasen et al., 2007]. The participants answered the Brazilian version of the Child Perceptions Questionnaire (CPQ11-14) - Impact Short Form, and their parents/guardians answered a structured questionnaire addressing demographic and socioeconomic characteristics. Data analysis involved Poisson regression with robust variance, with the calculation of rate ratios adjusted for potential confounding variables. High severity of dental caries experience exerted a significant impact on OHRQoL, even after controlling for socioeconomic and clinical factors (rate ratio 1.30; 95% confidence interval, CI 1.12-1.51). All OHRQoL domains were affected by untreated dental caries. The multivariate analysis demonstrated that the CPQ11-14 scores were 33% higher among adolescents with untreated caries (rate ratio 1.33; 95% CI 1.17-1.50) and 24% higher among those with missing teeth (rate ratio 1.24; 95% CI 1.06-1.47). No difference in OHRQoL was found between adolescents with filled teeth and those without dental caries. In conclusion, dental caries experience, untreated dental caries and missing teeth exerted a negative impact on OHRQoL among the adolescents. © 2016 S. Karger AG, Basel.

The aim of this study was to assess the impact of malocclusion on children's oral health-related quality of life (COHRQoL) and self-reported happiness. A cross-sectional study was conducted in a representative sample of 12-year-old schoolchildren from Santa Maria, South Brazil. Four calibrated examiners carried out clinical exams to evaluate malocclusion [Dental Aesthetic Index (DAI)], dental caries (DMFT), and dental trauma (O'Brien classification, used in the Children's dental health survey in the UK, 1994). Participants answered the Brazilian versions of the Child Perceptions Questionnaire (CPQ11-14 ) and the Subjective Happiness Scale (SHS). Parents completed a structured questionnaire regarding socioeconomic status. Data analysis was conducted using multilevel Poisson regression models. A total of 1,134 adolescents (boys: 45.8 percent; girls: 54.1 percent) were enrolled in the study. The DAI overall score ranged from 13 to 63 (mean: 25.19, standard error: 0.19); 57.6 percent of the subjects had minor or no malocclusion and 24.4 percent had definite malocclusion. Severe malocclusion and handicapping malocclusion were found in 10.4 percent and 7.4 percent of the subjects, respectively. After adjustment, the severity of malocclusion was associated with high mean values of the CPQ11-14 overall score, and the emotional well-being and social well-being domains were the most affected. Lower levels of happiness were also associated with the severity of malocclusion: those with definite malocclusion presented lower scores on the SHS scale (Rate Ratio 0.97; 95 percent CI 0.94-0.99). Malocclusion had a negative impact on COHRQoL and happiness, mainly on the emotional and social domains. © 2015 American Association of Public Health Dentistry.

A cross-sectional study was performed with parents of outpatients suffering from SCD at a hematology referral center in Belo Horizonte, MG. A qualified dentist performed an intraoral exam. The Family Impact Scale (FIS was used to assess the parents’ perception of QoL. The parents answered some questions regarding sociodemographic and medical information about their children. The dmft/DMFT score, DAI, gum bleeding and SCD severity were evaluated in terms of their impacts on the overall mean FIS scores and subscale scores. The chance of more frequent impacts was greater in parents of adolescents (OR = 2.04; 95%CI = 1.2, 3.4 than of younger children. Dental caries (dmft/DMFT ≥ 1 had a negative impact on the QoL of parents of younger children and adolescents (p < 0.05 and p < 0.01, respectively. Among the parents of younger children, dental caries and SCD severity significantly affected the subscales for parental activities (PA and parental emotions (PE (p < 0.01, p < 0.05, respectively. Among parents of adolescents, dental caries (DMFT and severe malocclusion adversely affected the PE and PA subscales (p < 0.01, p < 0.05, respectively. SCD severity affected the overall FIS score among young children’s parents (p < 0.05. In conclusion, dental caries, age and SCD severity were associated with a negative impact on the QoL of parents of children with SCD

Every year in Ireland over 400 people are diagnosed with head and neck cancer. Oral cancer, a specific type of head and neck cancer, is usually treated with surgery and often requires radiotherapy (RT). However, side effects of RT treatment, which include mucositis, xerostomia, radiation caries, trismus and osteoradionecrosis, can seriously compromise a patient's quality of life. Treatment for oral cancer patients is managed in a multidisciplinary team. General dental practitioners (GDPs), consultant/specialist dentists and oral-maxillofacial surgeons play an important role in these patients' care. Recent advances in the delivery of RT have not only improved locoregional control and survival rates, but have also reduced the incidence and severity of RT-associated side effects; however, no mode of RT delivery has successfully eliminated side effects. The role of dentists is essential in maintaining oral health and all patients should be dentally screened prior to commencing RT. Recent reports have attempted to standardise the quality of care for the oral cancer patient and have highlighted the significance of the role of the GDP. Despite the advancements in RT delivery, the dental team is still faced with a number of challenges, including the high number of patients lost to follow-up dental care, lack of an effective treatment for xerostomia, poor patient compliance, and a lack of standardised guidelines and funding. Addressing these challenges will involve increased communication between all members of the multidisciplinary team and increased involvement of the GDP, thereby ensuring that dental care continues to evolve concurrently with new methods of RT delivery.

The aim of this study was to test the association of contextual school and home environmental characteristics and individual factors with oral health-related quality of life (OHRQoL) in a representative sample of Brazilian adolescents and young adults. Individual-level data from 3854 fifteen- to nineteen-year-olds who participated in the Brazilian Oral Health Survey were pooled with contextual city-level data. The dependent variable was the frequency of impacts of oral disorders on daily performances (OIDP extent), as a measure of OHRQoL. Contextual school and home environmental characteristics were categorized into three equal groups according to tertiles of the contextual variable's scores (low, moderate and high). Individual demographic, socioeconomic and oral clinical measures were the covariates. The association between contextual and individual characteristics and OIDP extent was estimated using multilevel Poisson regression models. The mean of OIDP extent was 0.9 (standard error 0.1). Adolescents and young adults living in the cities with high levels of lack of security at school (RR 1.33; 95% CI=1.02-1.74), moderate levels of bullying at school (RR 1.56; 95% CI=1.20-2.03) and moderate levels of low maternal schooling (RR 1.43; 95% CI=1.06-1.92) had a higher mean OIDP extent. Male sex, higher age, skin colour, poor individual socioeconomic status and worse oral clinical measures were also associated with higher mean of OIDP extent. Poor school and home environmental characteristics were independently associated with poor OHRQoL in individuals aged between 15 and 19 years. Our findings suggest the place where they study and the maternal level of education are meaningful aspects for their oral health. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To determine the impact of removable partial dental prostheses on satisfying the daily functioning and quality of life (QoL) of adult patients with different distributions of missing posterior teeth. A cross-sectional interventional study was carried out on 80 patients having variously distributed posteriorly shortened and interrupted arches. Treatment comprised provision of partial dentures by senior dental students, supervised by senior clinical teachers who had knowledge of the potential benefits of the shortened dental arch (SDA) concept. The Oral Impacts on Daily Performance Index was completed before and 6 months after prosthetic treatment across groups comprising Kennedy Classes I, II, and III arches. Analysis included descriptive statistics and associations and comparisons between variables. Mean age of patients was 57.4 years (SD = 13.1), many were retired (72.2%), and a majority were females (60%). Most patients lived in urban areas (95%), and were largely unemployed (63.3%). At pretreatment, only 31.3% of patients reported having good dental health and satisfaction with their current oral state, while 82.5% said they had a great need for treatment. The negative oral impacts that were most frequently experienced were those of eating (67.5%), smiling (50%), and being emotionally disturbed (63.8%). Post-treatment, 76.3% indicated good oral health and satisfaction with no significant differences between the 3 Kennedy groups. Any further negative impacts were reported mostly for Kennedy Classes I and II. Overall, significant reductions of negative impacts were observed following treatment with dentures, across the 3 Kennedy groups, with respect to improved function, satisfaction, and oral health-related QoL. The findings confirm the reliance by partially dentate patients in all 3 Kennedy groups on dentures for improved oral health, although the possible benefits of the SDA concept as an alternative treatment option was not specifically explored. © 2017 by

Background and purpose: The relation between health-related quality of life (HRQOL) and survival was investigated at baseline and 6 months in 80 patients with advanced oral or oropharyngeal cancer after microvascular reconstructive surgery and (almost all) adjuvant radiotherapy. Materials and methods: Multivariate Cox regression analyses of overall and disease-specific survival were performed including sociodemographic (age, gender, marital status, comorbidity), and clinical (tumor stage and site, radical surgical, metastasis, radiotherapy) parameters, and HRQOL (EORTC QLQ-C30 global quality of life scale). Results: Before treatment, younger age and having a partner were predictors of disease-specific survival; younger age predicted overall survival. At 6 months post-treatment, disease-specific and overall survival was predicted by (deterioration of) global quality of life solely. Global health-related quality of life after treatment was mainly influenced by emotional functioning. Conclusion: Deterioration of global quality of life after treatment is an independent predictor of survival in patients with advanced oral or oropharyngeal cancer.

Radiation therapy (RT) and concurrent chemotherapy RT (CCRT) generate radiation-induced oral mucositis (OM) and lower quality of life (QOL). This study assessed the impact of a saline mouth rinse regimen and education programme on radiation-induced OM symptoms, and QOL in oral cavity cancer (OCC) patients receiving RT or CCRT. Ninety-one OCC patients were randomly divided into a group that received saline mouth rinses and an education programme and a control group that received standard care. OM symptoms and QOL were assessed with the WHO Oral Toxicity Scale, MSS-moo and UW-QOL. Data were collected at the first postoperative visit to the radiation department (T0) and at 4 weeks and 8 weeks after beginning RT or CCRT. Patients in both groups had significantly higher levels of physical and social-emotional QOL at 8 weeks after beginning RT or CCRT compared to the first visit. Patients in the saline rinse group had significantly better physical and social-emotional QOL as compared to the standard care group at 8 weeks. Radiation-induced OM symptoms and overall QOL were not different between the groups. We thus conclude the saline rinse and education programme promote better physical and social-emotional QOL in OCC patients receiving RT/CCRT. © 2018 John Wiley & Sons Ltd.

Objective To report the associations of oro-nasal fistulae on the patient-centered outcomes oral health–related quality of life and self-reported speech outcomes in school aged-children. Design Prospective, nonrandomized multicenter design. Setting Six ACPA-accredited cleft centers. Participants Patients with cleft palate at the age of mixed dentition. Interventions None. Main Outcome Measures Prevalence of fistula and location of fistula (Pittsburgh Classification System). Patients were placed into one of three groups based on the following criteria: alveolar cleft present, no previous repair (Group 1); alveolar cleft present, previously repaired (Group 2); no congenital alveolar cleft (Group 3). Presence of fistula and subgroup classification were correlated to oral health–related quality of life (Child Oral Health Impact Profile [COHIP]) and perceived speech outcomes. Results The fistula rate was 5.52% (62 of 1198 patients). There was a significant difference in fistula rate between the three groups: Group 1 (11.15%), Group 2 (4.44%), Group 3 (1.90%). Patients with fistula had significantly lower COHIP scores (F1,1188 = 4.79; P = .03) and worse self-reported speech scores (F1,1197 = 4.27; P = .04). Group 1 patients with fistula had the lowest COHIP scores (F5,1188 = 4.78, P =.02) and the lowest speech scores (F5,1188 = 3.41, P = .003). Conclusions Presence of palatal fistulas was associated with lower oral health–related quality of life and perceived speech among youth with cleft. The poorest outcomes were reported among those with the highest fistula rates, including an unrepaired alveolar cleft. PMID:26437081

To analyse the relationship between oral bacteria and the health and functional status of the elderly. The bacteria species in the oral cavity of the elderly were examined. It was found that the bedridden subjects staying at two hospitals for long-term (HOBR) showed significantly lower detection rates of commensal bacteria species and significantly higher detection rates of Pseudomonas aeruginosa, of methicillin-resistant Staphylococcus aureus (MRSA) and of coagulase(-) Staph. aureus than those living independently (the independent). In addition, the detection rate of Haemophilus parainfluenzae in NUBR was discovered to be higher than that found in the independent. In HOBR, the detection rate of Ps. aeruginosa was significantly higher among in-patients who required continual care than those in need of partial care, while the detection rate of MRSA was significantly higher among in-patients with low serum albumin than those with normal serum albumin. Oral bacteria examination analysis proved that the risks of infection of some pathogenic bacteria species were correlated with functional status, physical function and nutritional state. Our study suggests that the oral bacteria, especially pathogenic bacteria were influenced by the functional status of the elderly and the type and quality of the facilities for the bedridden, physical function and nutritional state.

Age-related deterioration in physical and oral health reduces healthy life expectancy and is thus an important problem for very elderly people. We investigated the effects of satisfaction with dietary life (SDL) in everyday life on oral health-related quality of life (OHRQoL) and subjective well-being and examined associations between these factors. We evaluated 426 elders aged 85 years or older. All participants completed a questionnaire that inquired about age, gender, drinking status, body mass index, cognitive function, disability, and comorbidities, among other covariates. Oral, physical, and mental health conditions were also examined. Associations of questionnaire results for SDL with items on subjective well-being (Philadelphia Geriatric Center Morale Scale [PGC] and World Health Organization-5 [WHO-5]) and OHRQoL (Geriatric Oral Health Assessment Index [GOHAI]) were confirmed with multiple logistic regression analysis. In a multivariate model adjusted for various confounders, participants with self-reported "enjoyable" SDL had significantly lower risks for having the lowest scores on the GOHAI, PGC, and WHO-5 (odds ratio [OR] = 0.460, 95% confidence interval [CI] = 0.277-0.762; OR = 0.589, 95% CI = 0.348-0.996; and OR = 0.452, 95% CI = 0.263-0.775, respectively). These associations remained after further adjustment for number of teeth.

Full Text Available Abstract Background A combination of artesunate (AS plus sulphadoxine/pyrimethamine (SP as first-line and artemether-lumefantrine (AL as second-line treatment are currently recommended against uncomplicated P. falciparum infection in Sudan. However, there is limited information on the efficacy of ACTs in the country and only one report of PCR-corrected results for AS/SP only. Methods The WHO protocol for the assessment of antimalarial drug efficacy for the treatment of uncomplicated falciparum malaria was employed. Artesunate plus sulphadoxine/pyrimethamine (AS/SP was compared to artemether-lumefantrine (AL in a 28-day follow up. Samples that were classified as early treatment failure (ETF, late treatment failure (LCF or late parasitological failure (LPF were genotyped for msp-1 and msp-2 genes to differentiate recrudescence from reinfection. Results A total of 178 patients were screened and 160 met the enrolment criteria and were recruited to the study of which 157 (98.1% completed the follow up and had an analysed treatment outcome. On the AS/SP arm, three (0.038% patients were lost during the follow-up, two on day 1 and one on day 7, and 77 (96.3 completed the study, while all 80 (100% patients completed the follow up in the AL arm. In the per protocol analysis for AS/SP the treatment outcome for patients who completed the follow-up were as follows: adequate clinical and parasitological response (ACPR; 84.4% ETF; 1.3%, LCF; 3.9%, (LPF; 10.4%. For the AL arm the out come was as follows, ACPR; 90%, ETF; 0%, LCF; 6.3% and LPF; 3.8%. However, when PCR-corrected, 6.5% (5/77 of patients treated with AS/SP maintained parasites from their primary infection, while (7/80 in the AL group maintained their initial parasite genotype. Therefore, PCR-corrected efficacy was 93.5% in the AS/SP treated group and for AL it was 91.3%. Conclusion Both AS/SP and AL are highly effective for the treatment of uncomplicated falciparum malaria in eastern Sudan. However

The primary objective of this study was to investigate the quality of life (QOL) of patients with oral squamous cell carcinoma (OSCC) undergoing curative neoadjuvant chemoradiotherapy followed by radical tumour resection and simultaneous oral cavity reconstruction, using two validated questionnaires. A secondary objective was to assess clinical variables predicting post-treatment dysfunction in chewing, saliva, and swallowing. Thirty-five patients with locally advanced OSCC who underwent preoperative chemoradiotherapy were recruited prospectively. All patients completed both the University of Washington Quality of Life version 4 questionnaire (UW-QOL) and the Functional Assessment of Cancer Therapy-Head & Neck version 4 questionnaire (FACT-H&N). UW-QOL and FACT-H&N items were associated with clinical variables. Nearly three-quarters of OSCC patients perceived good to excellent levels of overall QOL after preoperative chemoradiotherapy. Chewing difficulties, decreased salivary function, and swallowing dysfunction were the most frequent complaints of OSCC patients. Items related to food intake were significantly worse in OSCC patients older than 60 years and those with T4 tumours, as well as those without alcohol intake. Chewing, saliva, and swallowing are the most significant issues in patients with OSCC undergoing preoperative chemoradiotherapy. The results of this study may help guide treatment decisions for OSCC patients based on more accurate expectations of adverse effects of cancer treatment.

In order to identify whether demographic and oral health-related quality of life factors are associated with dental care attendance among an underprivileged older population, a comparison was performed between people who have and have not attended dental care. A cross-sectional purposive sample of 344 older underprivileged people comprised the study population. The dependent variable was dental care attendance. The 14-item version of the Oral Health Impact Profile index (OHIP-14) was used as the independent variable, together with other social and general variables, using a structured interview. The variables that were significantly associated with dental care attendance were family status (not married, the highest attendance), dwelling location (living at home, the highest attendance), caregiver (family member, the highest attendance), place of birth (Western countries, the highest attendance) and income (pension, the highest attendance). Sex, welfare support, functional ability, education, age and OHIP-14 were not associated with dental care attendance. Attending dental care was not associated with oral health-related quality of life measured by OHIP-14. Several socioeconomic variables were strongly associated. © 2010 The Authors.

To compare the satisfaction of patients treated with vitamin K antagonists (VKA) with that of patients treated with direct oral anticoagulants (DOACs) and to determine the impact on quality of life of both treatments in patients with nonvalvular atrial fibrillation (NVAF). Cross-sectional multicenter study in which outpatients with NVAF completed the ACTS (Anti-Clot Treatment Scale), SAT-Q (Satisfaction Questionnaire) and EQ-5D-3L (EuroQol 5 dimensions questionnaire, 3 level version) questionnaires. The study population comprised 1337 patients, of whom 587 were taking DOACs and 750 VKAs. Compared with VKAs, DOACs were more commonly prescribed in patients with a history of stroke and in patients with a higher thromboembolic risk. The study scores were as follows: SAT-Q: 63.8 ± 17.8; EQ-5D-3L total score: 75.6 ± 20.9; visual analog scale: 63.1 ± 20.6; ACTS Burdens: 51.8 ± 8.4 and ACTS Benefits: 11.9 ± 2.4. The ACTS Burdens score and ACTS Benefits score were higher with DOACs than with VKAs (54.83 ± 6.11 vs 49.50 ± 9.15; p patients treated with oral anticoagulants had many comorbidities and a high thromboembolic risk. Satisfaction and quality of life with oral anticoagulants were high, although they were both better with DOACs than with VKAs.

Objective: To evaluate the effect of implant related treatment on the oral health related quality of life (OHRQoL) of edentulous patients. Methods: The CNKI, Wanfang database and Medline, EMBASE, Cochrane Library databases that include randomized clinical trials comparing implant supported overdentures with conventional complete denture for edentulous patients were retrived. Nine studies involving 769 cases were included and meta-analysis was conducted. Results: The standardized mean difference (SMD) of oral health impact profile (OHIP) score was 1.63 (95% CI: 1.25-2.02) and improved after implant related treatment, which was significantly better than the conventional complete denture (0.87, 95% CI: 0.54-1.20). Conclusions: Implant supported overdentures improved patient's OHRQoL and showed better performance compared to the overdentures complete dentures.
Full Text Available Introduction: Nowadays, appraisal of patients' perception of health has largely replaced the clinical evaluations. This study aimed to compare oral health-related quality of life in patients referring to public and private clinics in Mashhad, Iran. Materials and Methods: In this cross-sectional study, we enrolled 383 patients referred to five private and two public dental clinics in Mashhad, Iran. The study variables including age, gender, level of education, functional dentition status, decayed, missing, and filled teeth, and the reason for referral were recorded. Oral Impact on Daily Performance (OIDP score was calculated for each patient. To analyze the data, independent samples t-test, Man-Whitney U test, and Chi-squared test were run. Results: The reason for visiting the public and private clinics was significantly different (P

The authors' objectives were to determine the percentage of children in kindergarten through grade 5 who reported symptoms of temporomandibular joint disorder (TMJD); to assess whether sex, race, and socioeconomic background mattered; and to explore the relationships between TMJD and children's oral health and oral health-related quality of life (OHRQoL). The research team conducted face-to-face interviews with 8,302 children in kindergarten through grade 5 (51% female, 49% male; 53% African American, 42% white). They conducted oral health screenings with 7,439 children. Overall, 23.6% of the children reported pain when chewing tough food, and 18.8% reported pain when opening their mouth wide; 23.2% reported hearing a sound (clicking) when opening their mouth wide. Female students were more likely than male students and African American children were more likely than white children to report TMJD symptoms. The prevalence of TMJD symptoms did not correlate with whether the children had a need for oral health care services or whether they had an abscess or carious teeth with pulpal involvement. TMJD symptoms were associated significantly with children's OHRQoL. Considerable percentages of 4- to 12-year-old children reported TMJD symptoms, with girls and African American children being more likely than their counterparts to be affected. Experiencing TMJD symptoms was associated significantly with poorer OHRQoL. Dental practitioners need to be aware that substantial percentages of kindergarten and elementary school-aged children experience TMJD symptoms. Taking a dental history and conducting an oral examination, therefore, should include assessments of the signs and symptoms of TMJD; treatment recommendations should be provided for affected children.

This study examined young, preschool children's oral health-related quality of life (OHRQoL) among a community-based cohort of English and Spanish-speaking parent-child dyads in North Carolina, and sought to quantify the association of parent/caregiver characteristics, including spoken language, with OHRQoL impacts. Data from structured interviews with 1,111 parents of children aged 6-23 months enrolled in the Zero-Out Early Childhood Caries study in 2010-2012 were used. OHRQoL was measured using the overall score (range: 0-52) of the Early Childhood Oral Health Impact Scale (ECOHIS). We examined associations with parents' sociodemographic characteristics, spoken language, self-reported oral and general health, oral health knowledge, children's dental attendance, and dental care needs. Analyses included descriptive, bivariate, and multivariate methods based upon zero-inflated negative binomial regression. To determine differences between English and Spanish speakers, language-stratified model estimates were contrasted using homogeneity χ 2 tests. The mean overall ECOHIS score was 3.9 [95% confidence interval (CI) = 3.6-4.2]; 4.7 among English-speakers and 1.5 among Spanish speakers. In multivariate analyses, caregivers' education showed a positive association with OHRQoL impacts among Spanish speakers [prevalence ratio (PR) = 1.12 (95% CI = 1.03-1.22), for every added year of schooling], whereas caregivers' fair/poor oral health showed a positive association among English speakers (PR = 1.20; 95% CI = 1.02-1.41). The overall severity of ECOHIS impacts was low among this population-based sample of young, preschool children, and substantially lower among Spanish versus English speakers. Further studies are warranted to identify sources of these differences in - actual or reported - OHRQoL impacts. © 2016 American Association of Public Health Dentistry.
meet key end points, and in December 2011, Novartis Pharma AG announced that it would not pursue further clinical development of oral calcitonin for postmenopausal osteoporosis or osteoarthritis. A unique feature of calcitonin is that it is able to uncouple bone turnover, reducing bone resorption without affecting bone formation and therefore increasing bone mass and improving bone quality. This effect, however, may be dose-dependent, with higher doses inhibiting both resorption and formation. Because so many factors affect the pharmacokinetics and pharmacodynamics of calcitonin, especially orally administered calcitonin, much work remains to be done to explore the full pharmacologic spectrum and potential of calcitonin and determine the optimum dose and timing of administration, as well as water and food intake.Keywords: oral calcitonin, osteoporosis, fractures, arthritis, pain

This study aims to evaluate the impact of untreated dental caries and its clinical consequences on the quality of life of Brazilian schoolchildren aged 8-10 years. A randomly selected sample of 587 children underwent a clinical oral examination for the assessment of untreated dental caries and clinical consequences. The WHO criteria (decayed component of the decayed, missing, and filled teeth--D-DMFT in permanent teeth or d-dfmt in primary teeth) and the PUFA index, which records the presence of severely decayed permanent (upper case) and primary (lower case) teeth with visible pulpal involvement (P/p), as well as ulceration caused by dislocated tooth fragments (U/u), fistula (F/f), and abscesses (A/a), were used for the oral examination. Oral health-related quality of life (OHRQoL) was evaluated using the Child's Perception Questionnaire (CPQ8-10). Poisson regression was employed to test unadjusted and adjusted associations between untreated dental caries/clinical consequences and OHRQoL. The prevalence of untreated dental caries was 64.6% (D/d component of DMFT/dmft > 0) and 17.9% of children exhibited clinical consequences of caries (PUFA/pufa index >0). In the adjusted models, untreated caries was significantly associated with the total CPQ8-10 score and all subscale scores. The clinical consequences of dental caries (PUFA/pufa index >0) were significantly associated with the total CPQ8-10 as well as the oral symptoms and functional limitations' subscales. Untreated dental caries and its clinical consequences exerted a negative impact on the OHRQoL of the schoolchildren analyzed.

Background. In treating malaria in Uganda, artemether-lumefantrine (AL) has been associated with a lower risk of recurrent parasitemia, compared with artesunate-amodiaquine (AS/AQ), but changing treatment practices may have altered parasite susceptibility. Methods. We enrolled 602 children aged 6–59 months with uncomplicated falciparum malaria from 3 health centers in 2013–2014 and randomly assigned them to receive treatment with AS/AQ or AL. Primary outcomes were risks of recurrent parasitemia within 28 days, with or without adjustment to distinguish recrudescence from new infection. Drug safety and tolerability and Plasmodium falciparum resistance–mediating polymorphisms were assessed. Results. Of enrolled patients, 594 (98.7%) completed the 28-day study. Risks of recurrent parasitemia were lower with AS/AQ at all 3 sites (overall, 28.6% vs 44.6%; P AQ (1.73 vs 1.39 g/dL; P = .04). Both regimens were well tolerated; serious adverse events were uncommon (1.7% in the AS/AQ group and 1.0% in the AL group). AS/AQ selected for mutant pfcrt/pfmdr1 polymorphisms and AL for wild-type pfcrt/pfmdr1 polymorphisms associated with altered drug susceptibility. Conclusions. AS/AQ treatment was followed by fewer recurrences than AL treatment, contrasting with older data. Each regimen selected for polymorphisms associated with decreased treatment response. Research should consider multiple or rotating regimens to maintain treatment efficacies. PMID:26597254

We evaluated the efficacy and effectiveness of mefloquine (MQ) plus artesunate (AS) to treat patients with uncomplicated malaria in the Peruvian Amazon Basin in April 2005-March 2006. Patients ≥ 1 year of age with fever (axillary temperature ≥ 37.5°C) or history of fever and Plasmodium falciparum monoinfection were included. Patients received antimalarial treatment with MQ (12.5 mg/kg/day for two days) and AS (4.0 mg/kg/day for three days) either by directly observed therapy or without directly observed therapy. After a 28-day follow-up, treatment efficacy and effectiveness were assessed on the basis of clinical and parasitologic outcomes. Ninety-six patients were enrolled in each study group; nine patients were lost to follow-up. All patients, except for one in the observed group, demonstrated adequate clinical and parasitologic response; none had detectable parasitemia on day 3. The efficacy of MQ + AS efficacy was 98.9% (95% confidence interval = 94.1-100.0%) and the effectiveness was 100.0% (95% confidence interval = 95.9-100.0%). Our study shows that MQ + AS is highly efficacious in the Peruvian Amazon.

A comprehensive plan for periodontal disease (PD) care in Taiwan provides non-surgical and supportive periodontal treatment. The aim of this study was to determine whether the care plan could improve the oral health-related quality of life of patients with PD.This study was conducted by purposive sampling and a quasi-experimental design. Patients with PD were assigned to either comprehensive periodontal treatment (n = 32) or a simple cleaning regimen (n = 32). Their oral health-related quality of life (OHRQoL) was measured using the Taiwanese version of the Brief World Health Organization Quality of Life (WHOQOL-BREF) scale (general QoL) and the Oral Health Impact Profile (OHIP-14) (OHRQoL). Both scales were completed 14, 28, and 90 days after the initial assessment. The extent of PD in the experimental group was determined again at the end of the study.On the 28-item WHOQOL-BREF scale, the scores of the experimental group were higher than those of the control group on 5 items and the environmental domain at 14 days. There was a significant improvement in the experimental group on 2 items at 28 days and at 90 days after periodontal treatment (both P improvement in the experimental group in total score at 28 and 90 days after periodontal treatment (both P plan for PD care showed some improvement in QoL, including in the environmental domain, and on the total score for OHRQoL. Comprehensive periodontal treatment also alleviated periodontal symptoms.

Childhood circumstances such as socio-economic status and family structure have been found to influence psychological, psychosocial attributes and Oral Health Related Quality of Life (OHRQoL) in children. Therefore, the aim of this study was to conduct a systematic review of the published literature to assess the influence of parental Socio-Economic Status (SES) and home environment on children's OHRQoL. A systematic search was conducted in August 2013 using PubMed, Medline via OVID, CINAHL Plus via EBSCO, and Cochrane databases. Studies that have analysed the effect of parental characteristics (SES, family environment, family structure, number of siblings, household crowding, parents' age, and parents' oral health literacy) on children's OHRQoL were included. Quality assessment of the articles was done by the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative studies. Database search retrieved a total of 2,849 titles after removing the duplicates, 36 articles were found to be relevant. Most of the studies were conducted on Brazilian children and were published in recent two years. Early Childhood Oral Health Impact Scale and Children's Perception Questionnaire were the instruments of choice in preschool and school aged children respectively. Findings from majority of the studies suggest that the children from families with high income, parental education and family economy had better OHRQoL. Mothers' age, family structure, household crowding and presence of siblings were significant predictors of children's OHRQoL. However, definitive conclusions from the studies reviewed are not possible due to the differences in the study population, parental characteristics considered, methods used and statistical tests performed.
CONCLUSION: In this survey, the influence of oral manifestation on OHQoL was low. Xerostomia was the most important symptom in diabetic patients that causes decreasing OHQoL. Age and blood sugar had more influence on this matter as well.

Purpose: The oral complications associated with radiotherapy to the head and neck are a significant dose-limiting factor. The goals of this study were to determine whether oropharyngeal rinsing and ingestion of misoprostol protect mucous membranes from the acute effects of irradiation, and to evaluate the quality-of-life (QOL) outcomes of patients receiving misoprostol. We report the results of the QOL outcomes of patients in this study. Methods and Materials: A total of 33 patients with resected or intact cancer of the oral cavity, oropharynx, supraglottic larynx, or hypopharynx were registered to receive postoperative radiotherapy plus misoprostol or primary radiotherapy plus misoprostol. All patients were scheduled to receive 60-70 Gy at 2 Gy/d within 6-7 weeks. QOL and function were evaluated. Results: A decrease in the QOL and function occurred in all areas covered by the questionnaire at the 6-week interval. This decrease was significant for eating, saliva, taste, and mucous. Of these significant factors, taste, saliva, and mucous consistency had not resolved by 12 weeks. Conclusion: Increased understanding of the impact of treatment on QOL and symptoms will formulate the rational design of toxicity interventions and enhance the multidisciplinary care of head-and-neck patients

Knowing what patients think about their care is fundamental to the provision of an effective, quality service, and it can help to direct change and reduce costs. Much of the work in oral and maxillofacial departments concerns the treatment of outpatients, but as little is known about what they think about their care, we aimed to find out which aspects were associated with satisfaction. Consecutive patients (n=244) who attended the oral and maxillofacial outpatient department at Southampton University Hospital NHS Foundation Trust over a 7-day period were given a questionnaire to complete before and after their consultation. It included questions with Likert scale responses on environmental, procedural, and interactive aspects of the visit, and a 16-point scale to rank their priorities. A total of 187 patients (77%) completed the questionnaires. No association was found between expected (p=0.93) or actual (p=0.41) waiting times, and 90% of patients were satisfied with their visit. Seeing the doctor, having confidence in the treatment plan, being listened to, and the ability of the doctor to recognise their personal needs, were ranked as important. Environmental and procedural aspects were considered the least important. These findings may be of value in the development of services to improve patient-centred care.

We report a case of an elderly patient with chronic periodontitis requiring periodontal surgery. An 86-year-old man presented to Tokyo Dental College Suidobashi Hospital with the chief complaint of tooth fracture in the anterior region and occlusal pain in the posterior region. Clinical examination revealed 47% of sites with a probing depth (PD) of ≥4 mm and 47% of sites with bleeding on probing. Radiographic examination revealed generalized moderate horizontal bone loss with localized vertical defects. A clinical diagnosis of moderate chronic periodontitis was made. The patient's oral health-related quality of life (QoL) was also assessed at the time of each periodontal assessment. Initial periodontal therapy was provided followed by periodontal surgery. Open flap debridement was performed at sites with a PD of ≥5 mm (teeth #15-17). Surgical crown lengthening with an apically positioned flap was performed on #11 and 13 to gain an adequate biological width for the subsequent crown restoration. After confirming the stability of the periodontal tissue, provisional restorations were replaced with final restorations. No further deterioration was observed in the periodontal condition during the subsequent 1-year period of supportive periodontal therapy. Oral health-related QoL was markedly improved by the periodontal therapy. This suggests that periodontal therapy plays an important role in improving and maintaining oral health-related QoL in elderly people.
Full Text Available BACKGROUND: Patent medicine vendors (PMV provide antimalarial treatment and care throughout Sub-Saharan Africa, and can play an important role in the fight against malaria. Their close-to-client infrastructure could enable lifesaving artemisinin-based combination therapy (ACT to reach patients in time. However, systematic assessments of drug sellers' performance quality are crucial if their role is to be managed within the health system. Lot quality assurance sampling (LQAS could be an efficient method to monitor and evaluate PMV practice, but has so far never been used for this purpose. METHODS: In support of the Nigeria Malaria Booster Program we assessed PMV practices in three Senatorial Districts (SDs of Jigawa, Nigeria. A two-stage LQAS assessed whether at least 80% of PMV stores in SDs used national treatment guidelines. Acceptable sampling errors were set in consultation with government officials (alpha and beta <0.10. The hypergeometric formula determined sample sizes and cut-off values for SDs. A structured assessment tool identified high and low performing SDs for quality of care indicators. FINDINGS: Drug vendors performed poorly in all SDs of Jigawa for all indicators. For example, all SDs failed for stocking and selling first-line antimalarials. PMV sold no longer recommended antimalarials, such as Chloroquine, Sulfadoxine-Pyrimethamine and oral Artesunate monotherapy. Most PMV were ignorant of and lacked training about new treatment guidelines that had endorsed ACTs as first-line treatment for uncomplicated malaria. CONCLUSION: There is urgent need to regularly monitor and improve the availability and quality of malaria treatment provided by medicine sellers in Nigeria; the irrational use of antimalarials in the ACT era revealed in this study bears a high risk of economic loss, death and development of drug resistance. LQAS has been shown to be a suitable method for monitoring malaria-related indicators among PMV, and should be

Artesunate (AS) is used in combination with amodiaquine (AQ) as first-line treatment for uncomplicated malaria in many countries. We investigated the effect of concomitant AS administration on the pharmacokinetics of AQ and compared concentrations of desethylamodiaquine (DEAQ), the main metabolite...... implications for weight-based dosing of higher-body-weight children with AQ. The pharmacokinetics of artemisinin combination therapies should be studied in malaria patients, because the rapid parasite clearance caused by the artemisinin may affect the kinetics of the partner drug and the combination....

the non-steroidal anti-inflammatory drug group. Paracetamol oral drops are indicated for use in infant population aged up to 5 years to relieve fever, headache, toothache and symptomatic relief of common cold. Objective: to validate two analytical methods for the quality control and the stability study and to study the stability of 100 mg/ml Paracetamol oral drops made in Cuba. Methods: for quantification of the active principle in the final product in order to study stability, a chromatographic column equipment called Lichrosorb RP-18 was used for separation (5µm (250 x 4 mm, with ultraviolet ray detection at 243 nm and a mobile phase made up of distilled water: methanol (3:1 and the quantification of this principle against a reference sample by using the external standard method. For the quality control, the spectrophotometry used the spectrophotometer SPECTRONIC GENESYS 2, the ideal wavelength was 245 nm since it matches the maximum absorption rate and there is no interference with the excipients.

Full Text Available Patients receiving radiotherapy or chemotherapy will receive some degree of oral mucositis The incidence of oral mucositis was especially high in patients: (i With primary tumors in the oral cavity, oropharynx, or nasopharynx; (ii who also received concomitant chemotherapy; (iii who received a total dose over 5,000 cGy; and (iv who were treated with altered fractionation radiation schedules. Radiation-induced oral mucositis affects the quality of life of the patients and the family concerned. The present day management of oral mucositis is mostly palliative and or supportive care. The newer guidelines are suggesting Palifermin, which is the first active mucositis drug as well as Amifostine, for radiation protection and cryotherapy. The current management should focus more on palliative measures, such as pain management, nutritional support, and maintenance, of good oral hygiene
Background Individuals connected to supportive social networks have better general and oral health quality of life. The objective of this study was to assess whether there were differences in oral health related quality of life (OHRQoL) between women connected to either predominantly home-based and work-based social networks. Methods A follow-up prevalence study was conducted on 1403 pregnant and post-partum women (mean age of 25.2 ± 6.3 years) living in two cities in the State of Rio de Janeiro, Brazil. Women were participants in an established cohort followed from pregnancy (baseline) to post-partum period (follow-up). All participants were allocated to two groups; 1. work-based social network group - employed women with paid work, and, 2. home-based social network group - women with no paid work, housewives or unemployed women. Measures of social support and social network were used as well as questions on sociodemographic characteristics and OHRQoL and health related behaviors. Multinomial logistic regression was performed to obtain OR of relationships between occupational contexts, affectionate support and positive social interaction on the one hand, and oral health quality of life, using the Oral Health Impacts Profile (OHIP) measure, adjusted for age, ethnicity, family income, schooling, marital status and social class. Results There was a modifying effect of positive social interaction on the odds of occupational context on OHRQoL. The odds of having a poorer OHIP score, ≥4, was significantly higher for women with home-based social networks and moderate levels of positive social interactions [OR 1.64 (95% CI: 1.08-2.48)], and for women with home-based social networks and low levels of positive social interactions [OR 2.15 (95% CI: 1.40-3.30)] compared with women with work-based social networks and high levels of positive social interactions. Black ethnicity was associated with OHIP scores ≥4 [OR 1.73 (95% CI: 1.23-2.42)]. Conclusions Pregnant and post

Full Text Available Abstract Background Plasmodium falciparum malaria remains a major public health problem. A vital component of malaria control rests on the availability of good quality artemisinin-derivative based combination therapy (ACT at the correct dose. However, there are increasing reports of poor quality anti-malarials in Africa. Methods Seven collections of artemisinin derivative monotherapies, ACT and halofantrine anti-malarials of suspicious quality were collected in 2002/10 in eleven African countries and in Asia en route to Africa. Packaging, chemical composition (high performance liquid chromatography, direct ionization mass spectrometry, X-ray diffractometry, stable isotope analysis and botanical investigations were performed. Results Counterfeit artesunate containing chloroquine, counterfeit dihydroartemisinin (DHA containing paracetamol (acetaminophen, counterfeit DHA-piperaquine containing sildenafil, counterfeit artemether-lumefantrine containing pyrimethamine, counterfeit halofantrine containing artemisinin, and substandard/counterfeit or degraded artesunate and artesunate+amodiaquine in eight countries are described. Pollen analysis was consistent with manufacture of counterfeits in eastern Asia. These data do not allow estimation of the frequency of poor quality anti-malarials in Africa. Conclusions Criminals are producing diverse harmful anti-malarial counterfeits with important public health consequences. The presence of artesunate monotherapy, substandard and/or degraded and counterfeit medicines containing sub-therapeutic amounts of unexpected anti-malarials will engender drug resistance. With the threatening spread of artemisinin resistance to Africa, much greater investment is required to ensure the quality of ACTs and removal of artemisinin monotherapies. The International Health Regulations may need to be invoked to counter these serious public health problems.
Full Text Available Aims and Objectives: The aim and objective of this study was to establish the relationship of oral health-related quality of life (OHRQoL as assessed by the Child Perception Questionnaire (CPQ 11–14 with the Index of Orthodontic Treatment Need (IOTN and the child's apprehension with his/her dental appearance and how upset the child would feel if he/she is unable to obtain orthodontic treatment. Materials and Methods: An observational cross-sectional study was conducted among 604 children between the age group of 10–14 years to analyze the effect of malocclusion on the quality of life of children on the basis of impact on oral symptoms, functional limitation, emotional well-being, and social well-being. Malocclusion was evaluated using the IOTN, and the CPQ 11–14 was used to study the OHRQoL in children. The collected data were then subjected to statistical analysis. Statistical Analysis: Spearman's correlation coefficient was used to analyze the data statistically. Results: Out of the 604 children examined, boys showed effect on emotional well-being, whereas girls showed a significant correlation on both emotional and social well-being. There was a statistically significant correlation between IOTN and all the four domains of CPQ scores with respect to the two questions that were added to the CPQ questionnaire. Conclusion: A questionnaire when developed specifically for determining the effect of malocclusion on OHRQoL focusing more on emotional and psychological impact and less on oral symptoms and functional limitation will provide advantages of having limited questions, being less time-consuming, and providing better understanding of the patients' concern.

Oral health-related quality of life (OHRQoL) is afflicted by different variables. Limited information is available regarding the impact of different phases of implant therapy on OHRQoL of edentulous patients. This study was carried out to assess the OHRQoL of patients treated with implant-supported single crowns or fixed partial dentures. A total of 79 healthy partially edentulous subjects needing implant therapy were incorporated in this study. Before placement of the implants, the subjects were instructed to fill the original version of OHIP questionnaire. Subsequently patients received titanium oral implants of the ITI® Dental Implant System. After 1st, 2nd and 3rd year of implant placement, patients filled the same OHIP-49 questionnaire. In this manner the impact of implant therapy on OHRQoL by putting in comparison pre- and post-treatment OHIP-49 scores was assessed. Statistical analyses were performed using Statistical Package for the Social Science software (SPSS, version 22, Chicago, IL, USA). Paired t test and Unpaired t test were performed and a statistical significance was set at 5% level of significance ( p disability, psychological disability, social disability were significantly decreased from baseline to 1st year ( p 0.05). All variables were also significantly decreased from baseline to 2nd year and 3rd year ( p 0.05). Patients aged less than 60 years and more than 60 years of age groups differed significantly with respect to OHIP scores measured at 1st year, 2nd year and at 3rd year of implant placement ( p Oral health-related quality-of-life.

In recent years, Artemisinin and particularly one of its derivatives--Artesunate (ART--has become an essential alternative for treatment of both uncomplicated and severe falciparum malaria in Asia and Africa as well. Therefore, these compounds are still and inccreasingly in the focus of interest because of quick acting of this drug, is able to help even unconscious to overcome the malaria attack, when administered by injection. As an alternative, RECTOCAPS have been developed and their use is meanwhile well established. From earlier studies in children, suffering from plasmodium falciparum malaria, we obtained a high level of DHART in the blood, but as expected also a rapid decline in the levels of both DHART and ART. A second administration of ART was additionally applied 4 hours after the first administration. DHART and ART plasma levels were found to last longer on an assumed therapeutic level than those obtained after one administration only. The fever clearance and the parasitemia reduction rates were found to be effective according to this dosing regimen. In view of these findings, we decided to conduct the actual described study by administering 200 mg of ART every 3 hours (0, 3, 6 and 9 h) by the rectal route. Soft geiatine capsules (RECTOCAPS) containing 200 mg of ART GMP--type each (Artesunic acid) were administered by rectal route. Each patient received four RECTOCAPS capsules (4 x 200 mg of ART) over a 3 h period. 12 adult patients with uncomplicated malaria were selected. Age, weight, height, body temperature, parasite counts before treatment and their evolution until 96 h are determined. Blood samples were taken at short time intervals after starting with the first medication: 0, 30 min, 60 min, 3 h, 6 h, 9 h, 12 h, 24 h, 36 h, 48 h, 60 h, 72 h, 84 h, 96 h and 108 h. The aliquots of all the blood samples were used for performing parasite counts. Plasma obtained following the traditional procedure was kept at -40 degrees C until analysis. HPLC

Full Text Available Hyposalivation (HS affects aging individuals by causing pain and discomfort in the oral cavity. The aim here was to determine the impact of hyposalivation and the saliva pH on the quality of life and caries status of geriatrics population. A total of 138 male outpatients attending the Taibah University College of Dentistry (TUCoD dental clinic were included in the study. The saliva flow, pH, Quality of Life (QoL, and caries status were recorded. The QoL was measured using the Arabic version of the Oral Health Impact Profile-14 (OHIP-14, and the caries status was recorded using the Decayed, Missed, Filled Teeth (DMFT index. The mean age was 67.5 years and 64% were classified as having hyposalivation. The older respondents tended to have a lower saliva flow and pH compared to their younger counterparts. There was a significant inverse association (p = 0.02 between the caries status and mean saliva flow rate. There was also a significant (p < 0.001 positive correlation between caries and the OHIP-14 scores (Spearman’s ρ = 0.293. The prevalence of hyposalivation was relatively high and there was an inverse relationship between the age, the saliva flow, and pH. Those with more caries reported significantly poor QoL.

Full Text Available OBJECTIVE: This study aimed to assess the survival and life quality evolution of patients subjected to surgical excision of oral and oropharyngeal squamous cell carcinoma. MATERIAL AND METHODS: Forty-seven patients treated at a Brazilian healthcare unit specialized in head and neck surgery between 2006 and 2007 were enrolled in the study. The gathering of data comprised reviewing hospital files and applying the University of Washington Quality of Life (UW-QOL questionnaire previously and 1 year after the surgery. Comparative analysis used Poisson regression to assess factors associated with survival and a paired t-test to compare preoperative and 1-year postoperative QOL ratings. RESULTS: 1 year after surgery, 7 patients were not found (dropout of the cohort; 15 had died and 25 fulfilled the UW-QOL again. The risk of death was associated with having regional metastasis previously to surgery (relative risk=2.18; 95% confidence interval=1.09-5.17 and tumor size T3 or T4 (RR=2.30; 95%CI=1.05-5.04. Survivors presented significantly (p<0.05 poorer overall and domain-specific ratings of quality of life. Chewing presented the largest reduction: from 74.0 before surgery to 34.0 one year later. Anxiety was the only domain whose average rating increased (from 36.0 to 70.7. CONCLUSIONS: The prospective assessment of survival and quality of life may contribute to anticipate interventions aimed at reducing the incidence of functional limitations in patients with oral and oropharyngeal cancer.
Full Text Available Sebastian Schneeweiss, Krista F Huybrechts, Joshua J Gagne Division of Pharmacoepidemiology and Pharmacoeconomics, Department of Medicine, Brigham and Women’s Hospital and Harvard Medical School, Boston, MA, USA Background: Dabigatran, an oral direct thrombin inhibitor, has now been available for 2 years in the US for the prevention of stroke in patients with nonvalvular atrial fibrillation, and direct Xa inhibitors are also starting to enter the market. Studies examining the effects of new oral anticoagulants in health care databases are beginning to emerge. The purpose of this study was to describe the validity of early published observational studies on the comparative safety and effectiveness of new oral anticoagulants in patients with atrial fibrillation. Methods: We identified published nonrandomized post-marketing studies (articles or conference abstracts or posters and critically appraised their internal validity, with a particular focus on their ability to control confounding and other biases. Results: Two full-length journal articles, three conference posters, two conference presentation abstracts, and a US Food and Drug Administration analysis form the basis of the early comparative effectiveness and safety experience with new oral anticoagulants. Some published studies exhibit substantial biases and have insufficient precision for several important endpoints. Several studies suffer from biases arising from comparing ongoing users of the older drug, warfarin, who seem to tolerate it, to initiators of the new treatment who may have switched from warfarin or have had no prior experience with anticoagulants. Analyses tended to not adjust or not adjust adequately for confounding, and unsound propensity score application was also observed. Several studies introduced selection bias by excluding patients who died during follow-up and by restricting the study population to those with continuous database enrollment following cohort entry.

To meaningfully interpret oral health-related quality of life (OHRQoL) measures, the influence of personality traits must be investigated. To investigate and quantify the influence of self-esteem and negative affectivity (NA) on OHRQoL. It was hypothesized that low self-esteem and high NA would be associated with worse OHRQoL. OHRQoL measured by the Oral Health Impact Profile 49 (OHIP-49), self-esteem measured by the Rosenberg Self-Esteem Scale (RSES), NA measured by the Eysenck Personality Inventory Questionnaire (EPI-Q), global oral rating of oral comfort and controlling variables (gender, age, number of teeth, experience of wearing removable dental prostheses (RDP), location of missing teeth and zone of missing teeth) were collected from 81 patients with partial tooth loss, signed in for treatment with RDP. Bivariate analyses showed that the EPI-Q score had the highest correlation with OHIP-49 score (R = 0.5). Both EPI-Q and RSES score had a stronger correlation with psychosocial items than physical/functional items of the OHIP-49. In the multivariate analyses, the controlling variables alone explained 17.75% of the variance in OHIP-49 score, while addition of EPI-Q score, RSES score and both EPI-Q and RSES score explained additionally 11.64%, 6.07% and 14.12%, respectively. For each unit increase in EPI-Q score, the OHIP-49 score increased 5.1 units and for each unit increase in RSES score, the OHIP-49 score decreased 1.1. NA was statistically and clinically significantly higher and self-esteem was statistically significantly lower in patients reporting worse oral comfort. NA had the strongest and most clinically meaningful influence, but both NA and self-esteem was found to influence OHRQoL; low self-esteem and high NA was associated with worse OHRQoL. This indicates the possibility to explain some of the impact of tooth loss on OHRQoL based on personality traits. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The healing pattern after surgical resection of tumors of the oral cavity involving the maxilla may vary from one patient to another. The result may be open communication between the oral and nasal cavities (open defect) or complete oronasal separation after healing of the defect area (closed defect). The purpose of this clinical study was to compare masticatory function and oral health-related quality of life (OHRQoL) between patients with closed and open defects who had undergone a partial maxillectomy and were wearing dentomaxillary prostheses. Thirty-eight participants who had undergone a partial maxillectomy and who were wearing dentomaxillary prostheses were enrolled between September 2014 and April 2016. Participants were assigned to 2 groups according to the type of defect after healing: 19 participants had a closed defect, and 19 participants had an open defect. Masticatory function was evaluated objectively and subjectively. The objective measurement was food-mixing ability, which was assessed using color-changeable chewing gum. The subjective measurement was perceived mastication ability, rated as a masticatory score based on the patient's responses to a 35-item food intake questionnaire. OHRQoL was assessed using the Geriatric Oral Health Assessment Index (GOHAI). The GOHAI questionnaire consists of 12 items reflecting 3 hypothesized domains of the impact of oral disease: physical function, psychosocial function, and pain or discomfort. Differences in the scores obtained by the 3 measurements were compared between the 2 groups, using the Wilcoxon rank-sum test (α=.05). No significant differences were seen between the 2 groups in objective mixing ability, subjective masticatory score, or GOHAI (P>.05). Regarding the GOHAI physical function domain, only the swallowing item was significantly lower (P=.025) in participants with an open defect than in participants with a closed defect. Regarding the GOHAI psychological function domain, the item related to

Oral Health-Related Quality-of-Life (OHRQoL) measures have been developed and cross-culturally validated for use in many populations in recent years. Their use in children with cleft lip and/or palate (CLP), however, is not as well established. This study aimed to validate two OHRQoL instruments for use with Cambodian children and to describe the OHRQoL of a sample of Cambodian children with CLP, compared with other children in the same cohort. A convenience sample of 133 children aged 2-8 years and their families was recruited from two NGO health services in urban and rural areas of Cambodia. Children were assigned into clinical groups of cleft, malocclusion, severe caries (PUFA ≥ 1), and dentine caries. OHRQoL was measured using the Parental-Caregivers Perception Questionnaire (P-CPQ-16) and Family Impact Scale (FIS-8). The validity of the instruments was acceptable with an expected gradient in both scale scores being evident across self-reported oral health ratings. Children with CLP and their families experienced significantly greater impacts on OHRQoL, and the pattern of these impacts differed among the clinical groups. This study has confirmed the validity of the P-CPQ-16 and FIS-8 for use with young Cambodian children. The results impart advocacy for needed improvements in the care of children with CLP and provide a foundation for future epidemiological research of oral health in Cambodia. © 2018 BSPD, IAPD and John Wiley & Sons A/S.

Patient-centred outcomes are being given great attention by the dental scientific community. The Oral Health Impact Profile -14 questionnaire (OHIP-14) has been introduced to address patients' success criteria when describing the impact of oral rehabilitations on quality of life (OHrQoL). Thirty-five patients wearing a full-arch implant-prosthesis being in place between 4 and 6 years before this analysis were considered eligible and then enrolled in the present retrospective study. According to their prosthetic anamnesis, two groups were defined: delayed loading group (IL-group) and immediate loading group (IL-group). At the moment of analysis, clinical and radiographic parameters were collected, and patients were asked to complete the Oral Health Impact Profile -14 questionnaire (OHIP-14) in order to measure their OHrQoL. Independent t-test showed total OHIP-14 scores to be not significantly different between groups; however, the domains "Functional limitation" and "physical disability" resulted significantly higher in patients within the DL-group. On the contrary, social disability was higher in the IL-group. When the comparison was performed taking sex into account, no significant differences between groups were highlighted. Instead, the stratification for years of follow-up led to significant evidences. When the follow-up was shorter (less-than-5 years), the functional limitation reported scores were higher. Within the limitations of this study, the analysis supports the absence of significant differences between immediate loading and delayed loading full-arch protocol in term of clinical, radiological parameters and OHrQoL.

To investigate the influence of clinical status and salivary conditions on the presence of xerostomia on adolescents with and without type 1 diabetes mellitus (DM1), and further to investigate the influence of clinical status, salivary conditions and xerostomia on oral health-related quality of life (OHQoL) of those with DM1. A cross-sectional study was performed on 102 adolescents, 51 with DM1 and 51 nondiabetics. Xerostomia was detected by asking a question about the sensation of having 'dry mouth', and Oral Health Impact Profile-14 was used to measure the impact of xerostomia on OHQoL. The clinical status was assessed by using decayed, missing or filled and Community Periodontal indices, and by evaluating oral manifestations; and the following salivary conditions were evaluated: stimulated salivary flow, pH, buffer capacity, total protein, amylase, urea, calcium, and glucose salivary concentrations. Multiple logistic regression analysis was used to evaluate the influence of clinical status and salivary conditions on xerostomia and the impact of xerostomia on the OHQoL of adolescents with DM1. Clinical status and salivary conditions was shown to have no influence on the presence of xerostomia. Bivariate (P = 0.00) and logistic regression (P = 0.01) analysis showed a significant association between DM1 and xerostomia. Logistic regression analysis showed association between xerostomia (P = 0.00) and OHQoL, and caries experience (P = 0.03) and OHQoL. DM1 showed to be predictive of a high prevalence of xerostomia in adolescents. Caries experience and xerostomia showed to have a negative impact on the OHQoL of adolescents with DM1. © 2011 John Wiley & Sons A/S.

This population-based, cross-sectional study explored the association between chronic periodontitis and oral health-related quality of life (OHRQoL) in Chinese adults, independently of sociodemographic factors and other common oral conditions. The present study was carried out in a sample population of 480 adults aged 35 to 74 years from Chongqing municipality. A multi-stage stratified random sampling approach was adopted to select participants. The Chinese version of the short-form oral health impact profile (OHIP-14) was used to assess OHRQoL. Chronic periodontitis was trichotomized into mild, moderate, and severe periodontitis. Logistic regression models were adopted to explore the association between the severity of chronic periodontitis and OHIP-14 scores. After adjustment for sociodemographic factors and other common clinical conditions, participants with severe and moderate chronic periodontitis, respectively, had 1.63- (95% CI: 1.41 to 1.98) and 1.42-fold (95% CI: 1.29 to 1.63) higher odds for the OHIP-14 scores being above the median compared with participants without chronic periodontitis. However, participants with mild periodontitis did not have significantly higher odds for the OHIP-14 scores being above the median than participants without chronic periodontitis. Certain sociodemographic variables, including higher age, lower education level, number of missing teeth, and current smoker, had negative associations with OHRQoL. Chronic periodontitis was associated with poorer OHRQoL in Chinese adults. In addition, the impairment in OHRQoL showed a significant correlation with the severity of chronic periodontitis. © 2018 American Academy of Periodontology.

This study aimed to compare two different tooth replacement strategies for partially dentate older patients; namely functionally orientated treatment according to the principles of the shortened dental arch (SDA) and conventional treatment using removable partial dentures (RPDs) using a randomised controlled clinical trial. The primary outcome measure for this study was impact on oral health-related quality of life (OHRQoL) measured using the short form of the oral health impact profile (OHIP-14). Patients aged 65 years and older were randomly allocated to two different treatment groups: the RPD group and the SDA group. For the RPD group each patient was restored to complete arches with cobalt-chromium RPDs used to replace missing teeth. For the SDA group, patients were restored to a premolar occlusion of 10 occluding pairs of natural and replacement teeth using resin bonded bridgework (RBB). OHRQoL was measured using the OHIP-14 questionnaire administered at baseline, 1 month, 6 months and 12 months after treatment intervention. In total, 89 patients completed the RCT: 44 from the RPD group and 45 from the SDA group. Analysis using a mixed model of covariance (ANCOVA) illustrated that treatment according to the SDA concept resulted in significantly better mean OHIP-14 scores compared with RPD treatment (premovable dentures in terms of impact on OHRQoL.

The purpose of this study was to compare patient satisfaction and oral health-related quality of life (OHRQoL) among fully edentulous patients treated with either fixed implant-supported prostheses (FP), removable implant-supported prostheses (RP), or complete dentures (CD). Eighty-six patients - 29 FP, 27 RP, and 30 CD patients - participated in this study. The survey was conducted using face-to-face interviews with a questionnaire that included a patient satisfaction scale and Oral Health Impact Profile (OHIP-14). We measured patient satisfaction after prosthetic treatments and OHRQoL before and after the treatments. After prosthetic treatments, OHRQoL increased in all three groups (P patient satisfaction and OHRQoL, and both groups showed greater improvement compared with the CD group. Specifically, the OHRQoL dimensions of functional limitation, physical pain, psychological discomfort, and psychological disability in the FP group, and functional limitation in the RP group, improved greatly in comparison with the CD group (P patient satisfaction than the CD treatment. Reliable information of OHRQoL and patient satisfaction helps experts and patients choose the best prosthetic treatment option. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The objective of the present study was to design and develop a formulation for orally disintegrating tablets (ODTs) of carbamazepine using quality by design principles. The target product profile (TPP) and quality target product profile (QTPP) of ODTs were identified. Risk assessment was carried out by leveraging prior knowledge and experience to define the criticality of factors based on their impact by Ishikawa fishbone diagram and preliminary hazard analysis tool. Box-Behnken response surface methodology was used to study the effect of critical factors on various attributes of ODTs. The independent factors selected were compression pressure (X 1 ), concentration of sublimating agent (volatile material) (X 2 ), disintegrant concentration (X 3 ) and the responses were tablet crushing strength, tablet porosity, disintegration time, water absorption time, tablet friability and drug dissolution. ANOVA and lack of fit test illustrated that selected independent variables had significant effect on the response variables, and excellent correlation was observed between actual and predicted values. Optimization by desirability function indicated that compression pressure, X 1 (1534 lbs), ammonium bicarbonate concentration, X 2 (7.68%) and Kollidon ® CL-SF concentration, X 3 (6%) were optimum to prepare ODT formulation of carbamazepine of desired attributes complying with QTPP. Thus, in the present study, a high level of assurance was established for ODT product quality and performance.

The features of a drop-on-demand-based system developed for the manufacture of melt-based pharmaceuticals have been previously reported. In this paper, a supervisory control system, which is designed to ensure reproducible production of high quality of melt-based solid oral dosages, is presented. This control system enables the production of individual dosage forms with the desired critical quality attributes: amount of active ingredient and drug morphology by monitoring and controlling critical process parameters, such as drop size and product and process temperatures. The effects of these process parameters on the final product quality are investigated, and the properties of the produced dosage forms characterized using various techniques, such as Raman spectroscopy, optical microscopy, and dissolution testing. A crystallization temperature control strategy, including controlled temperature cycles, is presented to tailor the crystallization behavior of drug deposits and to achieve consistent drug morphology. This control strategy can be used to achieve the desired bioavailability of the drug by mitigating variations in the dissolution profiles. The supervisor control strategy enables the application of the drop-on-demand system to the production of individualized dosage required for personalized drug regimens.

Early Childhood Caries (ECC) is an aggressive form of caries in a child who is 71 months of age or younger. If the child is cooperative, the treatment may be completed under Local Anaesthesia (LA). General Anaesthesia (GA) is considered if the child is uncooperative, medically compromised or if the parents are unable to return for regular visits and requests treatment under GA. Improved Oral health Related Quality of Life (OHRQoL) has been reported after dental treatment under GA. To assess and compare the improvements in OHRQoL of children who have undergone dental treatment under GA or LA. To study the preoperative severity of events that may prompt the parents to consider treatment under GA. Parents of paediatric patients who had to undergo full mouth rehabilitation under GA and LA were selected for this study. Parents were given a questionnaire to evaluate OHRQoL of children before and after completion of treatment. Preoperative and postoperative assessments were analyzed using paired t-test. Dental disease was found to have a significant impact on children's overall well being. There was a considerable improvement with relation to eating preferences, amount of food intake, sleep and pain relief before and after dental treatment. There was no significant difference if the child was treated under GA or LA. Severe caries affects the quality of life of preschool children and improvement on quality of life is significant regardless of treatment performed under GA or LA.

There is therefore a necessity for an adjuvant that maintains the quality of life (QOL and immune function of cancer patients receiving anthracycline-based chemotherapies.Patients and methods: The present study investigated the effectiveness of the concomitant use of Lentinula edodes mycelia extract (LEM, an oral immunomodulator, with FEC75 (5-fluorouracil + epirubicin + cyclophosphamide therapy on host QOL and immune function in breast cancer patients with nodal metastases. Ten breast cancer patients with nodal metastases receiving surgery were enrolled in this study. Treatment with 5-fluorouracil (500 mg/m2, epirubicin (75 mg/m2, and cyclophosphamide (500 mg/m2 was performed every 21 days for two courses, and LEM (1800 mg/day by mouth was administered during the second course.Results: In the first course, hematological toxicity was observed and host QOL and immune function were exacerbated. In the second course, however, the number of white blood cells and lymphocytes did not decrease and host QOL was maintained. Furthermore, the cytotoxic activities of natural killer (NK and lymphokine-activated killer cells and the proportion of activated NK and NK T-cells in lymphocytes were maintained in the second course.Conclusion: It has been suggested that the concomitant use of LEM with FEC75 therapy can maintain host QOL and immune function, and offer important implications for an application of LEM as a useful oral adjuvant to anthracycline-based chemotherapies
Full Text Available Myiasis is a pathologic condition in humans occurring because of parasitic infestation. Parasites causing myiasis belong to the order Diptera. Oral myiasis is seen secondary to oral wounds, suppurative lesions, and extraction wounds, especially in individuals with neurological deficit. In such cases, neglected oral hygiene and halitosis attracts the flies to lay eggs in oral wounds resulting in oral myiasis. We present a case of oral myiasis in 40-year-old male patient with mental disability and history of epilepsy.

Human papilloma virus (HPV)-associated head and neck cancer (HNC) has generated significant amount of research interest in recent times with focus shifted to oral cavity squamous cell cancer (OCSCC) after oropharyngeal cancer. Due to high incidence of OCSCC and anecdotal reports on association of HPV infection from northern region of India, this study was conceived to investigate HPV infection and establish its association with lifestyle habits such as tobacco, alcohol consumption, oro-genital sex, number of sexual contacts, and change in quality of life posttreatment. A total of 43 primary OCSCC biopsy specimens were collected. These samples were analyzed for HPV DNA genotyping which was done by using 13 high-risk HPV real-time PCR kits. Quality of life was assessed using University of Washington questionnaire for HNC patients, which was administered pretreatment and 3-months posttreatment. HPV presence was confirmed in only three patients (7.0 %). HPV positivity did not find any statistical correlation with age, gender, residence, addiction habit, stage, tumor size, nodal status, tumor grade, and number of sexual contacts. There was no significant ( p > 0.05) difference in the average percent change in QOL parameters from pretreatment to posttreatment when correlated with HPV status.
Full Text Available Introduction: Dental trauma has become an important attribute of dental public health inducing feelings of embarrassment to smile, laugh, and show teeth affecting social relationships. Available literature regarding the impact of dental trauma on the quality of life of children in Lucknow is scarce. Aims: To assess the impact of traumatic dental injuries (TDI on oral health-related quality of life (OHRQoL among 12-year-old school going children of Lucknow. Materials and Methods: A cross-sectional survey was conducted among 12-year-old Lucknow school children. A total of 492 school children were selected through multistage cluster random sampling. The participants completed the child perceptions questionnaire (CPQ 11-14 - impact short form: 16 followed by an assessment of TDI. Unpaired t-test was used to determine the association of TDI with CPQ 11-14 because it involved two separate groups; one with dental trauma and other without dental trauma. Results: The prevalence of TDI was 10.8%. Maxillary central incisors (8.73% were the frequently traumatized teeth. Enamel fracture (7.11% was the most common type of TDI. OHRQoL had statistically significant association with TDI. Conclusions: TDI has a negative impact on OHRQoL of children affecting their personal relationships and school performance.

To verify the hypotheses that treatment with double-crown-retained removable partial dentures (RPDs) improves oral health-related quality-of life (OHRQoL) over a 36-month period and that the performance of RPDs retained by use of electroplated double crowns (EP-RPDs) was different to that of RPDs retained by use of cast double crowns (C-RPDs). Fifty-four patients (mean age = 64 years, 63% men) were recruited and randomly assigned to C-RPD or EP-RPD. OHRQoL was assessed pre-treatment, post-treatment and 6, 12, 24 and 36 months after insertion, by use of the oral health impact profile (OHIP). An unweighted total score was calculated (OHIP-SUM). A two-level hierarchical model was used for statistical analysis. First-level units were the measurements on the six occasions; second-level units were the patients. Improvement of OHRQoL was observed in both groups after treatment (t = 7.27, p < 0.001). Whereas a treatment-material interaction indicated that treatment with EP-RPDs resulted in greater immediate improvement of OHRQoL, a time-material interacti
