    Oral lichen planus is an autoimmune disorder with several challenges in treatment. Photodynamic therapy has been proposed as a new treatment option for the disease. The present study compared the clinical effects of photodynamic therapy to dexamethasone mouthwash in the treatment of oral lichen planus lesions. In this randomized clinical trial, 30 patients with oral lichen planus were included.15 patients were treated with 5% methylene blue mediated photodynamic therapy using Fotosan device for 30s (630nm wavelength and 7.2-14.4J/cm 2 dose) for 4 sessions in the days 1, 4, 7, 14. In another group, the treatment was done on 15 patients by 0.5mg tab dexamethasone solution in 5cc water, rinsed 4 times in a day within two weeks. The sign score, symptoms scores (pain), clinical severity and treatment efficacy were measured at the days 15, 30, 60, 90 after beginning of the treatment. The results were subjected to Mann-whitney U test in both groups. No significant difference existed between the two modalities regarding the treatment efficacy index, sign score, symptom score and clinical severity on the 15, 30, 60 and 90 post-treatment days. Decreases in patient's symptoms were statistically significant in both groups. Photodynamic therapy was as effective as the dexamethasone mouth wash in the treatment of oral lichen planus. It could be used as a safe modality in the treatment of oral lichen planus lesions without identified side effects. Copyright © 2017 Elsevier B.V. All rights reserved.

    Objectives: In this review, we discuss the treatment of refractory overactive bladder (OAB) that has not adequately responded to medication therapy and we propose an appropriate care pathway to the treatment of OAB. We also attempt to address the cost of OAB treatments. Materials and Methods: A selective expert review of the current literature on the subject of refractory OAB using MEDLINE was performed and the data is summarized. We also review our experience in treating refractory OAB. The role and outcomes of various treatment options for refractory OAB are discussed and combined therapy with oral anticholinergics is explored. Emerging remedies including intravesical botulinum toxin injection and pudendal neuromodulation are also reviewed, along with conventional surgical options. Results: In general behavioral therapy, pelvic floor electrical stimulation, magnetic therapy and posterior tibial nerve stimulation (PTNS), have shown symptom decreases in 50-80% of patients with OAB. Depending on the study, combination therapy with oral anticholinergics seems to improve efficacy of behavioral therapy and PTNS in approximately 10-30%. In multicenter, long-term randomized controlled trials, sacral neuromodulation has been shown to improve symptoms of OAB and OAB incontinence in up to 80% of the patients treated. Studies involving emerging therapies such as pudendal serve stimulation suggest that there may be a 15-20% increase in efficacy over sacral neuromodulation, but long-term studies are not yet available. Another emerging therapy, botulinum toxin, is also showing similar success in reducing OAB symptoms in 80-90% of patients. Surgical approaches, such as bladder augmentation, are a last resort in the treatment of OAB and are rarely used at this point unless upper tract damage is a concern and all other treatment options have been exhausted. Conclusion: The vast majority of OAB patients can be managed successfully by behavioral options with or without

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

    Comprehensive management of patients receiving radiotherapy to the head and neck dictates that they have a thorough dental evaluation as part of their overall treatment planning. Early and appropriate patient education and dental treatment, along with careful management during and after radiotherapy, will significantly decrease the incidence and severity of complications, improve quality of life, and increase tolerance to therapy. 49 refs.; 16 figs.; 1 table

    Psychiatric medications may have serious and untoward adverse effects such as blurred vision, restlessness, agranulocytosis, muscle rigidity, and tremors. When compared to medications, electroconvulsive therapy (ECT) is becoming a more acceptable treatment due to its efficacy, tolerability, and minimal adverse effect profile. Oral trauma can be an ECT-related adverse effect. We reviewed the published literature on oral health and dental protection in patients undergoing ECT, and found that there are deficits in all guidelines on dental protection during ECT. Dental assessment and treatment before and after ECT is warranted. Given the increased risk of poor oral health in psychiatric patients, and the continued evolution of ECT as a mainstay treatment, it is important that studies be conducted to determine the optimal method of oral protection. If adequate care can be ensured, the risks of ECT-induced oral trauma will be minimized.

    The initial effect of anticancer therapy, such as radiation and chemotherapy, is on the rapidly proliferating cells of the oral epithelium. As a consequence, the epithelium may show atrophy and ulceration. The sites of these alterations are related to the rate of epithelial proliferation. Regions of rapid proliferation, such as the oral lining mucosa, show a greater frequency of ulceration than masticatory mucosa or skin. Subsequent changes in the mucosa reflect damage to connective tissue, including fibroblasts and blood vessels. This results in hyalinization of collagen, hypovascularity, and ischemia. Indirect effects of anticancer therapy may include granulocytopenia and reduced salivary secretion, so that the protective mucin coating of the epithelium is compromised. These changes result in tissue with reduced barrier function and impaired ability to heal and to resist entry of pathogens, thus increasing the risk of systemic infections

    Approximately 24,000 patients are diagnosed each year with malignant tumors of the head and neck. Many of these patients will be treated with radiotherapy, surgery, or chemotherapy, either singly or in combination. Certain predictable sequelae of radiotherapy exist that may be considered consequences of treatment rather than complications; these may be unavoidable consequences of curative radiotherapy to the head and neck. There are, however, additional problems that occur as a result of radiotherapy that are preventable in both incidence and severity, and are therefore avoidable complications. Cell kinetic factors, radiosensitivity of normal tissues, radiotherapeutic doses necessary for tumor control, and the complex anatomy of the maxillofacial region often predispose patients serious treatment morbidity. The potential for pain, infection, and long-term functional disability with decreased quality of life dictate conscientious management before, during, and after radiotherapy. This chapter discusses common problems that can arise, as well as current methods utilized both to improve patient tolerance to treatment and to decrease the risk of preventable and potentially dose-limiting morbidity

    2014-01-01

    With cancer survival rate climbing up over the past three decades, quality of life for cancer patients has become an issue of major concern. Oral health plays an important part in one's overall quality of life. However, oral health status can be severely hampered by side effects of cancer therapies including surgery, chemotherapy, radiotherapy, and hematopoietic stem cell transplantation. Moreover, prevention and treatment of these complications are often overlooked in clinical practice. The present paper aims at drawing health care professionals' attention to oral complications associated with cancer therapy by giving a comprehensive review. Brief comments on contemporary cancer therapies will be given first, followed by detailed description of oral complications associated with cancer therapy. Finally, a summary of preventive strategies and treatment options for common oral complications including oral mucositis, oral infections, xerostomia, and dysgeusia will be given. PMID:24511293

    The efficacy of oral steroid therapy for autoimmune pancreatitis (AIP) is well known, and oral prednisolone treatment is most usually commenced at 30-40 mg/day, but there have been few reports about comparative studies of oral steroid therapy and steroid pulse therapy as the initial treatment for AIP. We studied the clinical course and image findings to estimate the utility of steroid pulse therapy for AIP, comparing it with oral steroid therapy. Laboratory and image findings were assessed retrospectively in 11 patients who received steroid pulse therapy, and the findings were compared to those in 10 patients who received conventional oral steroid therapy. Change in pancreatic size showed no significant difference between the therapies after 2 weeks of treatment. Significant improvement of lower bile duct strictures after 2 weeks of treatment and that of immunoglobulin values within 6 months were shown with both therapies. However, steroid pulse therapy showed significant improvement of γ-guanosine triphosphate (GTP) in 2 weeks and of alanine aminotransferase (ALT) in 2 and 8 weeks, compared with oral steroid therapy. Moreover, there was one patient in whom the lower bile duct stricture was not improved by oral steroid therapy, but it did show improvement with steroid pulse therapy. Initial steroid pulse therapy is a beneficial alternative to oral steroid therapy for the improvement of bile duct lesions. In future, the accumulation of a larger number of patients receiving steroid pulse therapy is needed, and prospective studies will be required. (author)

    A number of acute oral complications may be associated with cancer therapy in children, but the extent and duration of these complications, and the most effective management techniques. have not been well described. The few studies differ in design, making comparisons difficult. Well-controlled, prospective clinical studies are needed to define the most effective strategies for the management of acute oral complications in children. However, it is clear that dental intervention prior to cancer therapy is an important factor in the optimal preparation of the patient. During cancer therapy, intensive supervised oral preventive protocols appear to be of benefit to the child's oral health, overall comfort, and well-being. Furthermore, the prevention of oral infection may significantly reduce the morbidity associated with cancer therapy. Long-term preventive oral care may help prevent dental disease and infection in medically compromised children and contribute to improving the quality of life. 41 references

  15. Measurement of warfarin in the oral fluid of patients undergoing anticoagulant oral therapy.

    Silvia Ghimenti

    Full Text Available BACKGROUND: Patients on warfarin therapy undergo invasive and expensive checks for the coagulability of their blood. No information on coagulation levels is currently available between two controls. METHODOLOGY: A method was developed to determine warfarin in oral fluid by HPLC and fluorimetric detection. The chromatographic separation was performed at room temperature on a C-18 reversed-phase column, 65% PBS and 35% methanol mobile phase, flow rate 0.7 mL/min, injection volume 25 µL, excitation wavelength 310 nm, emission wavelength 400 nm. FINDINGS: The method was free from interference and matrix effect, linear in the range 0.2-100 ng/mL, with a detection limit of 0.2 ng/mL. Its coefficient of variation was <3% for intra-day measurements and <5% for inter-day measurements. The average concentration of warfarin in the oral fluid of 50 patients was 2.5±1.6 ng/mL (range 0.8-7.6 ng/mL. Dosage was not correlated to INR (r = -0.03, p = 0.85 but positively correlated to warfarin concentration in the oral fluid (r = 0.39, p = 0.006. The correlation between warfarin concentration and pH in the oral fluid (r = 0.37, p = 0.009 confirmed the importance of pH in regulating the drug transfer from blood. A correlation between warfarin concentration in the oral fluid and INR was only found in samples with pH values ≥7.2 (r = 0.84, p = 0.004. CONCLUSIONS: Warfarin diffuses from blood to oral fluid. The method allows to measure its concentration in this matrix and to analyze correlations with INR and other parameters.

    Full Text Available Oral cancers account for a relatively high percent of neoplasms in the elderly population. Treatment protocols often include anti-neoplastic pharmaco-therapeutics, irradiation of the head and neck region, and surgery. These treatments, specially radiation, have detrimental effects on oral hard and soft tissues. Salivary glands undergo a distinct and longterm dysfunction, which leads to decrease in salivary How. Xerostomia is a common clinical problem in these patients which contributes to dry mouth, mucosites, change in oral ecosystem and dental caries, followed by difficulties in speech, swallowing and use of dentures which cause malnutrition. This phenomenon has an irreversible weakening effect on the patient's health. To prevent this negative impact on oral health in this group of patients, definitive dental treatments prior to the initiation of medical therapies is imperative, and will decrease the morbidity rates. Today's dentistry benefits from improved methods and materials, which enable us to give these patients a better preventive dental treatment. Consultation between dentist and medical team would be the best way to help our sufferer patients.

    We hypothesized that oral rehydration therapy using an oral rehydration solution may be effective for preoperative fluid and electrolyte management in surgical patients before the induction of general anesthesia, and we investigated the safety and effectiveness of oral rehydration therapy as compared with intravenous therapy. Fifty female patients who underwent breast surgery were randomly allocated to two groups. Before entry to the operation room and the induction of general anesthesia, 25 patients drank 1000 ml of an oral rehydration solution ("oral group") and 25 patients were infused with 1000 ml of an intravenous electrolyte solution ("intravenous group"). Parameters such as electrolyte concentrations in serum and urine, urine volume, vital signs, vomiting and aspiration, volumes of esophageal-pharyngeal fluid and gastric fluid (EPGF), and patient satisfaction with the therapy (as surveyed by a questionnaire) were assessed. After treatment, the serum sodium concentration and the hematocrit value, which both declined within the normal limits, were significantly higher in the oral group than in the intravenous group (sodium, 140.8 +/- 2.9 mEq x l(-1) in the oral group and 138.7 +/- 1.9 mEq x l(-1) in the intravenous group; P = 0.005; hematocrit, 39.03 +/- 4.16% in the oral group and 36.15 +/- 3.41% in the intravenous group; P = 0.01). No significant difference was observed in serum glucose values. Urine volume was significantly larger in the oral group (864.9 +/- 211.5 ml) than in the intravenous group (561.5 +/- 216.0 ml; P rehydration therapy, as judged by factors such as "feeling of hunger", "occurrence of dry mouth", and "less restriction in physical activity". The volume of EPGF collected following the induction of anesthesia was significantly smaller in the oral group than in the intravenous group (6.03 +/- 9.14 ml in the oral group and 21.76 +/- 30.56 ml in the intravenous group; P rehydration therapy with an oral rehydration solution before surgery is

    Intra-oral electron therapy for carcinoma of the oral cavity is a well-established treatment modality. However, the conventional metallic tubes were inconvenient to use because the irradiation field had to be confirmed by a side mirror. We devised transparent acrylic tubes which enable the positioning easy by confirming the tumor and irradiation field directry. Seven cases of various intra-oral carcinomas were treated with these new transparent acrylic tubes and good results were obtained. (author)

    Full Text Available Aim of the Study: Oral leukoplakia (OL is the most common potentially malignant disorder that may transform into oral carcinoma. By treating leukoplakia in its incipient stage, the risk of occurrence of oral carcinoma can be prevented. In this aspect, photodynamic therapy (PDT can serve as a useful treatment modality. The aim of the study is to treat patients with OL using PDT in which 5-aminolevulinic acid (ALA is used as a photosensitizer. Materials and Methods: Five patients with OL were included in the study. They were treated with 10% ALA mediated PDT (light source: Xenon lamp, power: 0.1 W, wavelength: 630 ± 5 nm, total dose: 100 J/cm 2 per session for 6-8 sessions. Follow-up was done for a period of 1 year. Results: One month (4 weeks after ALA-PDT, the response was evaluated based on clinical examination. It was as follows: Complete response: Two patients; partial response: Two patients; and no response: One patient. There was no recurrence in any of the cases. Conclusion: There was satisfactory reduction in the size of the OL lesion without any side-effects. Thus, ALA mediated PDT seems to be a promising alternative for the treatment of OL.

    Low-level laser therapy has been widely used in treating many conditions, including oral mucositis. The purpose of this study was to evaluate the occurrence of oral mucositis in patients undergoing antineoplastic therapy submitted to preventive and therapeutic treatment with low-level laser therapy. This cross-sectional study was carried out with 51 children and adolescents of both sexes with malignant neoplasias who developed oral mucositis and underwent low-level laser therapy. Data were collected on sex, age, type and degree of neoplasia, region affected, and remission time. 64.7% of the patients were male and were between 3 and 6 years of age (39.2%). Acute lymphoid leukemia was the most frequent neoplasm (37.3%). Regarding the maximum oral mucositis, grade 2 (41.2%) was predominant, with jugal mucosa (29.9%) and tongue (17.7%) being the most affected regions. The majority of cases presented lesion remission time between 4 and 7 days (44.0%). Most patients were young, male, and diagnosed with acute lymphoid leukemia. Predominance of grade 2 oral mucositis was observed, with jugal mucosa and tongue being the most affected regions, with the majority of cases presenting lesion remission time between 4 and 7 days. Low-level laser therapy has been shown to be an essential therapy in the prevention and treatment of these lesions, since it is a non-invasive and low-cost method.

    A controlled, randomised trial comparing the results of oral rehydration therapy with those of intravenous fluid treatment in 470 children with severe gastroenteritis was undertaken. The oral rehydration therapy was divided into two phases--a rehydration phase that used high sodium isotonic fluid at 40 ml/kg per hour and a maintenance phase using low sodium isotonic fluid (sodium 40, potassium 30, bicarbonate 25, chloride 45, and dextrose 130 mmol/l). The results indicate that oral rehydration treatment, used according to this protocol, is successful in treating severe diarrhoea and dehydration, and has considerable advantages over intravenous fluid therapy in reducing complications associated with the treatment of hypernatraemia, in promoting rapid correction of hypokalaemia and acidosis, in decreasing the duration of diarrhoea, and in promoting a greater weight gain at hospital discharge.

    Amphotericin B (AmB) remains the "gold standard" for systemic antifungal therapy, even though new drugs are emerging as the attractive antifungal agents. Since AmB has negligible oral absorption as a consequence of its unfavorable physicochemical characterizations, its use is restricted to parenteral administration which is accompanied by severe side effects. As greater understanding of the gastrointestinal tract has developed, the advanced drug delivery systems are emerging with the potential to overcome the barriers of AmB oral delivery. Much research has demonstrated that oral AmB formulations such as lipid formulations may have beneficial therapeutic efficacy with reduced adverse effects and suitable for clinical application. Here we reviewed the different formulation strategies to enhance oral drug efficacy, and discussed the current trends and future perspectives for AmB oral administration in the treatment of antifungal infections.

    Rasmussen, Rune Skovgaard; Corell, Pernille; Madsen, Poul

    2012-01-01

    : Patients randomized to computer-assisted anticoagulation and the CoaguChek® system reached the therapeutic target range after 8 days compared to 14 days by prescriptions from physicians (p = 0.04). Time spent in the therapeutic target range did not differ between groups. The median INR value measured...... prescribed by physicians, and the total time spent within the therapeutic target range was similar. Thus computer-assisted oral anticoagulant therapy may reduce the cost of anticoagulation therapy without lowering the quality. INR values measured by CoaguChek® were reliable compared to measurements......UNLABELLED: BACKGROUND: Computer-assistance and self-monitoring lower the cost and may improve the quality of anticoagulation therapy. The main purpose of this clinical investigation was to use computer-assisted oral anticoagulant therapy to improve the time to reach and the time spent within...

    To assess the efficacy of an orally administered antioxidant dietary supplement for managing marginal dry eye. A prospective, randomised, placebo controlled trial with cross-over. Eye Clinic, Department of Vision Sciences, Glasgow Caledonian University. Forty marginal dry eye sufferers composed of 30 females and 10 males (median age 53 y; range 38-69 y). Baseline assessments were made of tear volume sufficiency (thread test), tear quality (stability), ocular surface status (conjunctival impression cytology) and dry eye symptoms (questionnaire). Each subject was administered courses of active treatment, placebo and no treatment, in random order for 1 month each and results compared to baseline. Tear stability and ocular surface status were significantly improved following active treatment (Ptreatment (P>0.05). Absolute increase in tear stability correlated with absolute change in goblet cell population density. Tear volume was not improved following any treatment period and dry eye symptom responses were subject to placebo effect. Oral antioxidants improved both tear stability and conjunctival health, although it is not yet understood whether increased ocular surface health mediates increased tear stability or vice versa. This study was supported by a PhD scholarship funded by the Department of Vision Sciences, Glasgow Caledonian University, Scotland. Antioxidant supplements and placebos were kindly donated by Vitabiotics.

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

    Oral 4, 5', 8 trimethoxypsoralen (TMP) or 8-M-methoxypsoralen (8 MP) plus black light therapy of psoriasis produced disappearing of lesions in 6 out of 8 pacients treated with TMP and in 6 out of 7 treated with 8 MP. In three patients treated with the first drug, a paired comparision demonstrated that the ingestion of it, when followed of black exposure, is more effective than the exposure to conventional ultraviolet light. Parrish et al. have shown this for oral methoxalen and long wave ultraviolet light. Combined TMP or 8-MP and black light therapy inhibits epidermal DNA synthesis and this is the scientific base of its application in the therapy of psoriasis, disease in which an accelerated celular cicle and DNA synthesis has been postulated.

Vitamin K antagonists (VKA have been the standard of care for long-term OAT for decades, but non-VKA oral anticoagulants (NOAC have recently been approved for this indication, and raised many questions, among them their influence on medication adherence. We assessed adherence to VKA and NOAC in secondary stroke prevention. Methods: All patients treated from October 2011 to September 2012 for ischemic stroke or transient ischemic attack with a subsequent indication for OAT, at three academic hospitals were entered into a prospective registry, and baseline data and antithrombotic treatment at discharge were recorded. At the 1-year follow-up, we assessed the adherence to different OAT strategies and patients’ adherence to their respective OAT. We noted OAT changes, reasons to change treatment, and factors that influence persistence to the prescribed OAT. Results: In patients discharged on OAT, we achieved a fatality corrected response rate of 73.3% (n=209. A total of 92% of these patients received OAT at the 1-year follow-up. We observed good adherence to both VKA and NOAC (VKA, 80.9%; NOAC, 74.8%; P=0.243 with a statistically nonsignificant tendency toward a weaker adherence to dabigatran. Disability at 1-year follow-up was an independent predictor of lower adherence to any OAT after multivariate analysis, whereas the choice of OAT did not have a relevant influence. Conclusion: One-year adherence to OAT after stroke is strong (>90% and patients

    Radiation therapy is reported to induce oxidative stress in oral cancer patients. Saliva as a diagnostic tool has received increasing attention in recent years. Saliva analysis is proposed to be a noninvasive, sensitive tool for the evaluation of biological effects of radiation therapy in oral cancer. We aimed to assess the effect of radiation therapy on malondialdehyde, the marker of lipid peroxidation, and total antioxidant capacity in blood and saliva of oral cancer patients. We also aimed to assess the correlation between blood and saliva with respect to malonaldehyde (MDA) level and total antioxidant capacity (TAC). Thirty, clinically diagnosed oral cancer patients visiting the Oncology Department were the subjects. Thirty age- and sex-matched normal, healthy controls were included. Blood and saliva samples were collected from controls, and from oral cancer patients before and after radiation therapy. The samples were analyzed for MDA and TAC by standard spectrophotometric methods. Oral cancer patients showed significantly higher MDA level and lower TAC in blood and saliva when compared to controls. One week after radiation therapy, there was significant increase in MDA and decrease in TAC in oral cancer patients. After the completion of radiation therapy of six weeks, MDA level decreased and TAC increased, restoring the values near-to-controls. The pattern of change in MDA and TAC was similar between blood and saliva. There was significant correlation between blood and saliva with respect to MDA and TAC in oral cancer patients. Oral cancer patients showed increased oxidative stress and impaired antioxidant capacity. After radiation therapy of one week, oxidative stress increased further, and after six weeks of radiation therapy there was amelioration of antioxidant status. Saliva could be a sensitive and convenient laboratory tool for diagnosis of oral cancer and evaluation of biological effects of radiation therapy. (author)

    Full Text Available Abstract Background Adherence to oral antidiabetic medications is often suboptimal. Adherence differences may contribute to health disparities for black diabetes patients, including higher microvascular event rates, greater complication-related disability, and earlier mortality. Methods In this longitudinal retrospective cohort study, we used 10 years of patient-level claims and electronic medical record data (1/1/1992–12/31/2001 to assess differences in short- and long-term adherence to oral antidiabetic medication among 1906 newly diagnosed adults with diabetes (26% black, 74% white in a managed care setting in which all members have prescription drug coverage. Four main outcome measures included: (1 time from diabetes diagnosis until first prescription of oral antidiabetic medication; (2 primary adherence (time from first prescription to prescription fill; (3 time until discontinuation of oral antidiabetic medication from first prescription; and (4 long-term adherence (amount dispensed versus amount prescribed over a 24-month follow-up from first oral antidiabetic medication prescription. Results Black patients were as likely as whites to initiate oral therapy and fill their first prescription, but experienced higher rates of medication discontinuation (HR: 1.8, 95% CI: 1.2, 2.7 and were less adherent over time. These black-white differences increased over the first six months of therapy but stabilized thereafter for patients who initiated on sulfonylureas. Significant black-white differences in adherence levels were constant throughout follow-up for patients initiated on metformin therapy. Conclusion Racial differences in adherence to oral antidiabetic drug therapy persist even with equal access to medication. Early and continued emphasis on adherence from initiation of therapy may reduce persistent racial differences in medication use and clinical outcomes.

    According to the practice guidelines of the American Burn Association on burn shock resuscitation, intravenous (IV) fluid therapy is the standard of care for the replacement of fluid and electrolyte losses in burn injury of ≥20% of the total body surface area. However, in mass burn casualties, IV fluid resuscitation may be delayed or unavailable. Oral rehydration therapy (ORT), which has been shown to be highly effective in the treatment of dehydration in epidemics of cholera, could be an alternate way to replace fluid losses in burns. A prospective case series of three patients was carried out as an initial step to establish whether oral Ceralyte®90 could replace fluid losses requiring IV fluid therapy in thermal injury. The requirement of the continuing IV fluid therapy was reduced by an average of 58% in the first 24 hours after the injury (range 37-78%). ORT may be a feasible alternative to IV fluid therapy in the resuscitation of burns. It could also potentially save many lives in mass casualty situations or in resource-poor settings where IV fluid therapy is not immediately available. Further studies are needed to assess the efficacy of this treatment and to determine whether the present formulations of ORT for cholera need modification. PMID:22283039

    A study of 101 patients with early carcinomas of the oral cavity, T1 and T2, treated by external cobalt 60 beam and/or intra-oral cone (IOC) radiation therapy between 1964 through 1980 was made. The two year disease-free survival rate, including surgical salvage, was 88% and the local control rate was 85%. The incidence of radiation complications, i.e., soft tissue ulceration and/or osteoradionecrosis, was 14% and varied with various tumor sites and radiation doses delivered. The present review shows that local control and radiation complications are closely related to radiation doses and varies with different tumor sites of the oral cavity. Radiation therapy dosages expressed in terms of TDF values for these lesions are herein recommended. With proper selections of lesions arising from the oral cavity, combined external beam and IOC radiation therapy has been found extremely efficacious in achieving good local tumor control and high survival rates with excellent cosmetic and functional results and minimum radiation sequalae

    Full Text Available Menopause is a key point moment in the specific aging process of women. It represents a universal evolution in life. Its initiation is defined by a 12-month amenorrhea following the ultimate menstrual period. It encompasses a series of different biologic and physiologic characteristics. This period of life appears to spot a decline in a series of skin functional performances initiating tissue atrophy, withering, and slackness. Any part of the skin is possibly altered, including the epidermis, dermis, hypodermis, and hair follicles. Hormone replacement therapy (oral and nonoral and transdermal estrogen therapy represent possible specific managements for women engaged in the climacteric phase. All the current reports indicate that chronologic aging, climacteric estrogen deficiency, and adequate hormone therapy exert profound effects on various parts of the skin.

    Full Text Available Background: The incidence of recurrent tinea infections after oral terbinafine therapy is on the rise. Aim: This study aims to identify the appearance of incomplete cure and relapse after 2-week oral terbinafine therapy in tinea corporis and/or tinea cruris. Materials and Methods: A total of 100 consecutive patients clinically and mycologically diagnosed to have tinea corporis and/or tinea cruris were included in the study. The enrolled patients were administered oral terbinafine 250 mg once daily for 2 weeks. All clinically cured patients were then followed up for 12 weeks to look for any relapse/cure. Results: The common dermatophytes grown on culture were Trichophyton rubrum and Trichophyton tonsurans in 55% and 20% patients, respectively. At the end of 2-week oral terbinafine therapy, 30% patients showed a persistent disease on clinical examination while 35% patients showed a persistent positive fungal culture (persisters at this time. These culture positive patients included all the clinically positive cases. Rest of the patients (65/100 demonstrated both clinical and mycological cure at this time (cured. Over the 12-week follow-up, clinical relapse was seen in 22 more patients (relapse among those who had shown clinical and mycological cure at the end of terbinafine therapy. Thus, only 43% patients could achieve a long-term clinical and mycological cure after 2 weeks of oral terbinafine treatment. Majority of the relapses (16/22 were seen after 8 weeks of completion of treatment. There was no statistically significant difference in the body surface area involvement or the causative organism involved between the cured, persister, or relapse groups. Conclusions: Incomplete mycological cure as well as relapse is very common after standard (2-week terbinafine therapy in our patients of tinea cruris/corporis.

    Preoperative fluid and electrolyte management is usually performed by intravenous therapy. We investigated the safety and effectiveness of oral rehydration therapy (ORT) for preoperative fluid and electrolyte management of surgical patients. The study consisted of two studies, designed as a prospective observational study. In a pilot study, 20 surgical patients consumed 1000 mL of an oral rehydration solution (ORS) until 2 h before induction of general anesthesia. Parameters such as serum electrolyte concentrations, fractional excretion of sodium (FENa) as an index of renal blood flow, volume of esophageal-pharyngeal fluid and gastric fluid (EPGF), and patient satisfaction with ORT were assessed. In a follow-up study to assess the safety of ORT, 1078 surgical patients, who consumed ORS until 2 h before induction of general anesthesia, were assessed. In the pilot study, water, electrolytes, and carbohydrate were effectively and safely supplied by ORT. The FENa value was increased at 2 h following ORT. The volume of EPGF collected following the induction of anesthesia was 5.3±5.6 mL. In the follow-up study, a small amount of vomiting occurred in one patient, and no aspiration occurred in the patients. These results suggest that ORT is a safe and effective therapy for the preoperative fluid and electrolyte management of selected surgical patients.

    The purpose of this study was to assess the value of sucralfate suspension in prevention of oral mucositis and for reduction of oral pain in patients who develop mucositis during radiation therapy. The study was a double-blind, placebo-controlled, randomized prospective trial of a sucralfate suspension in the prevention and management of oral mucositis during radiation therapy. Oral mucositis was assessed using a quantitative scale and symptoms were assessed using visual analogue scales. The statistical model was developed to detect a 40% reduction in mucositis. No statistically significant reduction in mucositis was seen. Early during radiation therapy less oral pain was reported in the sucralfate group, but as treatment progressed all patients experienced pain. Patients in the sucralfate group were prescribed topical and systemic analgesics later in the course of radiation therapy. Prophylactic oral rinsing with sucralfate did not prevent oral ulcerative mucositis. Sucralfate may reduce the experience of pain during radiation therapy. 32 refs., 3 tabs

    Biofilm-related infections of the oral cavity, including dental caries and periodontitis, represent the most prevalent health problems. For years, the treatment thereof was largely based on antibacterial chemical agents. Recently, however, there has been growing interest in the application of more preventive and minimally invasive biotechnological methods. This review focuses on the potential applications of enzymes in the treatment and prevention of oral diseases. Dental plaque is a microbial community that develops on the tooth surface, embedded in a matrix of extracellular polymeric substances of bacterial and host origin. Both cariogenic microorganisms and the key components of oral biofilm matrix may be the targets of the enzymes. Oxidative salivary enzymes inhibit or limit the growth of oral pathogens, thereby supporting the natural host defense system; polysaccharide hydrolases (mutanases and dextranases) degrade important carbohydrate components of the biofilm matrix, whereas proteases disrupt bacterial adhesion to oral surfaces or affect cell-cell interactions. The efficiency of the enzymes in in vitro and in vivo studies, advantages and limitations, as well as future perspectives for improving the enzymatic strategy are discussed. © 2016 International Union of Biochemistry and Molecular Biology, Inc.

    Both operation and irradiation can cure a high percentage of patients with oral cavity carcinomas. The decision as to which modality is best (or whether to combine both modalities or offer only palliative treatment) in a particular patient is frequently complex and involves consideration of a number of factors before rational therapy can be planned. 1. Tumor location and distribution. 2. Tumor volume. 3. Tumor differentiation. 4. Known patterns of spread. 5. Functional, rehabilitative, and cosmetic aspects and their impact on the patient's life style and occupation. 6. The wishes of the patient and family. 7. Availability of a given treatment in the patient's geographic area. 8. Experience of the patient's physicians. 9. Anticipated cure rates with the various modes of therapy. 10. Expense. 11.

    2015-04-01

    Traditionally, perioperative nutritional management centered on fluid therapy, but in recent years, with the spread of enhanced recovery after surgery (ERAS) protocols, the utility of oral rehydration therapy (ORT) has been reported. There are few reports, however, on the safety of using jelly type oral rehydration solutions for ORT. We examined the effects of OS-1 jelly on gastric fluid and investigated its safety. A total of 147 patients (age range, 4-91 years), scheduled for elective surgery at our institution for whom ORT was indicated, were enrolled in this study. If the surgery was scheduled for the morning, patients were given two bottles of 200 g OS-1 jelly during the previous evening meal. If surgery was scheduled for the afternoon, two additional 200 g bottles were given to the patient with the morning meal on the day of surgery. Patients were allowed to drink water until two hours before the surgery. Gastric fluid was aspirated with a gastric tube after anesthesia induction, after which, volume and pH were measured. In all cases, gastric content was aspirated as a liquid, not a jelly. The volume and pH were 11.4 ± 14.6 ml and 2.8 ± 2.2, respectively. No major difference was seen in comparison with the data for OS-1 liquid. No postoperative aspiration pneumonia or reflux of gastric contents at the time of anesthesia induction was seen in any of the patients. From the present findings, if the time of water intake is strictly controlled, preoperative rehydration therapy using jelly-type oral rehydration solution is thought to be safe and comparable to liquid solution regarding its effects on gastric fluid.

    Hemangioma and vascular malformations in the field of oral and maxillofacial surgery is a pathology more often found in recent years in patients. The aim of this study was to evaluate the efficacy of the laser photocoagulation performed with a diode laser (Ga-Al-As) 980 nm wavelength in the treatment of vascular lesions which are located on the oral and maxillofacial areas, using color Doppler ultrasonography for evaluation of the results. We also made a comparison between laser therapy and sclerotherapy in order to establish treatment protocols and recommendations associated with this pathology. We conducted a controlled study on a group of 92 patients (38 male and 54 female patients, with an average age of 36 years) having low flow hemangioma and vascular malformations. Patients in this trial received one of the methods of treatment for vascular lesions such as hemangioma and vascular malformations: laser therapy or sclerotherapy. After laser therapy we have achieved a reduction in size of hemangioma and vascular malformations treated with such a procedure, and the aesthetic results were favorable. No reperfusion or recanalization of laser treated vascular lesions was observed after an average follow-up of 6 to 12 months. In case of sclerotherapy a reduction in the size of vascular lesions was also obtained. The 980 nm diode laser has been proved to be an effective tool in the treatment of hemangioma and vascular malformations in oral and maxillofacial area. Laser therapy in the treatment of vascular lesions was more effective than the sclerotherapy procedure.

    The efficacy and toxicity of sequential intravenous and oral ciprofloxacin therapy was compared with intravenously administered ceftazidime in a prospective, randomized, controlled, non-blinded trial. Thirty-two patients (16 patients receiving ciprofloxacin and 16 patients receiving ceftazidime) with 38 infections caused by susceptible Pseudomonas aeruginosa, enteric gram-negative rods, Salmonella group B, Serratia marcescens, Pseudomonas cepacia, and Xanthomonas maltophilia at various sites were evaluable for determination of efficacy. Length of therapy varied from seven to 25 days. Concomitant antimicrobials included intravenously administered beta-lactams for gram-positive organisms, intravenous/oral metronidazole and clindamycin for anaerobes, and intravenous/local amphotericin B for Candida albicans. Intravenous administration of 200 mg ciprofloxacin every 12 hours to 11 patients produced peak serum levels between 1.15 and 3.12 micrograms/ml; trough levels ranged between 0.08 and 0.86 micrograms/ml. Overall response rates were similar for patients receiving ciprofloxacin and ceftazidime. Emergence of resistance was similar in both groups--one Enterobacter cloacae and two P. aeruginosa became resistant after ciprofloxacin therapy and two P. aeruginosa became resistant after ceftazidime therapy. The frequency of superinfection with a variety of organisms was also similar in both groups. Adverse events related to ciprofloxacin included transient pruritus at the infusion site and generalized rash leading to drug discontinuation (one patient each), and with ceftazidime adverse effects included pain at the site of infusion and the development of allergic interstitial nephritis (one patient each). Overall, intravenous/oral ciprofloxin therapy appears to be as safe and effective as intravenous ceftazidime therapy in the treatment of a variety of infections due to susceptible aerobic gram-negative organisms.

    Full Text Available Introduction: The risk of postoperative hemorrhage from oral surgical procedures has been a concern in the treatment of patients who are receiving long-term anticoagulation therapy. A study undertaken in our institution to address questions about the amount and severity of bleeding associated with minor outpatient oral surgery procedures by assessing bleeding in patients who did not alter their anticoagulant regimen. Subjects and Methods: Eighty-three patients receiving long-term anticoagulant therapy visited Department of Oral and Maxillofacial Surgery from May 2010 to October 2011 for extractions and minor oral surgical procedures. Each patient was required to undergo preoperative assessment of prothrombin time (PT and measurement of the international normalized ratio. Fifty-six patients with preoperative PT values within the therapeutic range 3-4 were included in the study. The patients′ age ranged between 30 and 75 years. Application of surgispon was done following the procedure. Extraction of teeth performed with minimal trauma to the surrounding tissues, the socket margins sutured, and sutures removed after 5 days. Results: There was no significant incidence of prolonged or excessive hemorrhage and wound infection and the healing process was normal.

    Attempts, at social marketing of oral rehydration therapy (ORT) through television, in changing the knowledge and practice of mothers with regard to its use was assessed. One hundred and eighty seven consecutive mothers (38 excluded due to non use of ORT) were administered a preplanned questionnaire to assess their socio-economic profile, educational status, concept of diarrhea and correct use of ORT. Fifty nine mothers who watched these programmes on TV regularly formed the study group. These were compared with 90 mothers who had gained such knowledge from non-television sources. The correct application of knowledge of ORT was significantly better in study group compared with control group. The educational status of mothers had a positive impact on motivation to use ORT at home in the study group. Mass media campaigns through "TV spots" is an effective way of improving knowledge of mothers on ORT in a developing country.

    A cleidocranial dysplasia is an autosomal dominant inherited condition consisting of generalized skeletal disorder. Associated dental signs are present in 93,5%; failure of tooth eruption with multiple supernumerary teeth, dilaceration of roots, crown germination, microdontia, high arched palate, midface hypoplasia, high gonion angle. The molecular- genetic analysis revealed a missense mutation in the CBFA1 gene located on chromosome 6p21, which is considered to be etiological factor for CCD. Orthodontic and oral surgery therapy of a 13 year-old child with CCD was performed due to aesthetic and functional problems. The supernumerary germs were removed and the teeth were aligned with orthodontic appliances. Temporary functional rehabilitation was solved with partial denture. The presented case and the literature data support the importance of early diagnosis of CCD. The good collaboration of the orthodontic and maxillo-facial surgery specialists help achieve the correct rehabilitation of the patient.

    Oral lichen planus (OLP) is a relatively common chronic immunologic mucocutaneous disorder. Although there are many presenting treatments, some of them proved its failure. Recently, the use of photodynamic therapy (PDT) has been expanding due to its numerous advantages, as it is safe, convenient, and non-invasive and has toxic effect towards selective tissues. This article provides comprehensive review on OLP, its etiology, clinical features and recent non-pharmacological treatments. We also describe the topical PDT and its mechanisms. Our purpose was to evaluate the efficacy of PDT in treatment of OLP through collecting the data of the related clinical studies. We searched in PubMed website for the clinical studies that were reported from 2000 to 2014 using specific keywords: “photodynamic therapy” and “treatment of oral lichen planus”. Inclusion criteria were English publications only were concerned. In the selected studies of photodynamic treatment, adult patients (more than 20 years) were conducted and the OLP lesions were clinically and histologically confirmed. Exclusion criteria were classical and pharmacological treatments of OLP were excluded and also the using of PDT on skin lesions of lichen planus. We established five clinical studies in this review where all of them reported improvement and effectiveness of PDT in treatment of OLP lesions. The main outcome of comparing the related clinical studies is that the photodynamic is considered as a safe, effective and promising treatment modality for OLP. PMID:25883701

    We performed preoperative combined therapy using nedaplatin (CDGP) and radiation in 12 patients with squamous cell carcinoma originating from the oral cavity and maxillary sinus, and examined for any adverse events that may have occurred during this therapeutic regimen. Regarding the irradiation, external irradiation utilizing a 6 MV linac (linear accelerator) at a dose of 2.0 Gy/day was performed 5 times a week, with the target total radiation dose set at 40 Gy. In addition, CDGP was intravenously administered 30 minutes before irradiation at a dose of 5 mg/m{sup 2}/day. Mucositis was observed in all 12 subjects, however, the severity was observed to be grade 1-2 with no major differences in comparison to the patients given standard radiation monotherapy. Two subjects developed grade 3 leucopenia and were thus given granulocyte colony stimulating factor (G-CSF). In addition, grade 2 and grade 3 thrombocytopenia were both observed in one subject each. The subject with grade 3 thrombocytopenia required a platelet transfusion during surgery. No marked changes in serum creatinine levels were noted. These findings are therefore considered to provide evidence supporting the safety of this combination therapy. (author)

    2013-01-01

    Full Text Available Background: Oral minipulse (OMP therapy with methylprednisolone is presently one of the most common oral treatments used for progressive vitiligo in children. The treatment is usually given for a period of 6 months during which majority of patients are reported to go into remission. However, there are no follow-up studies to comment upon what happens to the disease after OMP therapy is withdrawn. Aim of the study: To document the incidence of relapse over a period of 1 year after OMP therapy is stopped in children with vitiligo. Materials and Methods: The study was conducted in 180 patients of childhood vitiligo (<15 years of age who had been on OMP therapy with oral methylprednisolone for at least 6 months and who had achieved a complete remission of their disease during the treatment period. The enrolled patients were followed up for a period of 1 year and examined clinically for any sign of reactivation of their disease over either the old lesions or at any new area of the body. Results: Forty-two patients were lost and could not complete the follow-up period of 1 year. Out of the 138 patients available at the end of 1 year, relapse was observed in 48 patients (34.8%. Rest of 90 patients remained in remission over the follow-up period of 1 year. Relapse was more common in patients below 10 years of age (47.4% as compared with older children (25.9%. Conclusion: Relapse after using methylprednisolone OMP therapy in children with vitiligo is quite common especially in younger age groups. Studies are needed to see whether these relapses could be avoided by giving the treatment for a period longer than 6 months.

    An increase in quantity of oral Candida albicans was documented in patients receiving head and neck radiation therapy during and after therapy, as assessed by an oral-rinse culturing technique. The amount of the increase was greater in denture wearers and directly related to increasing radiation dose and increasing volume of parotid gland included in the radiation portal. A significant number of patients who did not carry C. albicans prior to radiation therapy developed positive cultures by 1 month after radiation therapy. The percentage of patients receiving head and neck radiation therapy who carried C. albicans prior to radiation therapy did not differ significantly from matched dental patient controls

    Objective: This study aimed at investigating the factors affecting medication adherence in patients who use oral iron therapy due to iron deficiency anemia. Methods: A total of 96 female patients in fertile age with mean age of 30±10.1 years (range 18-53) who were admitted to Family Medicine Clinic between 01 January and 31 March 2015 and who had received iron therapy within the recent three years were enrolled in the study. Data were collected through a questionnaire form. Results: Of the patients, 39 (40,6%) were detected not to use the medication regularly or during the recommended period. A statistically significant relationship was found between non-adherence to therapy and gastrointestinal side effects and weight gain (p<0.05). Conclusion: Medication adherence is deficient in patients with iron deficiency anemia. The most important reason for this seems gastrointestinal side effects, in addition to weight gain under treatment. PMID:27375698

    Inflammatory bowel diseases (IBD) are associated with an altered systemic immune response leading to inflammation-mediated damage to the gut and other organs. Oral immune therapy is a method of systemic immune modulation via alteration of the gut immune system. It uses the inherit ability of the innate system of the gut to redirect the systemic innate and adaptive immune responses. Oral immune therapy is an attractive clinical approach to treat autoimmune and inflammatory disorders. It can induce immune modulation without immune suppression, has minimal toxicity and is easily administered. Targeting the systemic immune system via the gut immune system can serve as an attractive novel therapeutic method for IBD. This review summarizes the current data and discusses several examples of oral immune therapeutic methods for using the gut immune system to generate signals to reset systemic immunity as a treatment for IBD.

    Background: Oral mucositis remains one of the most common and troubling side effects of antineoplastic radiation and drug therapy: its incidence in onco-hematological radio-chemotreated patients is variable between 50 and 100% and its impact on this populations is directly linked with the experience of intense pain causing reduction and modification of therapy regimens, decreased survival rates and increased cost of care. Purpose: Aim of this study is the preliminary evaluation of a Low Level Laser therapy (LLLT) protocol on healing process of oral mucositis and on pain and quality of life of patients experiencing this dramatic side-effect. Materials and methods: Patients were evaluated and treated at the Unita` Operativa Semplice Dipartimentale di Odontostomatologia e Chirurgia Maxillo-Facciale of the Hospital of Piacenza were they were treated for primary disease with protocols of chemotherapy and/or radiotherapy. LLLT protocol was performed with a diode laser (808 nm -XD Smile - Fotona -Slovenia) on a two weeks-6 treatments schedule with power of 0.5 W and application of 30 seconds. Mucositis grading was scored on the basis of WHO classification by two blind operators at each treatment and at 1 and 2 weeks after treatment. Pain and capability of deglutition were described by patients by means questionnaires based on Visual Analogue Scale, Numerical Rating Scale and Quality of Life. Results: A relevant improvement of healing of oral mucositis, in terms of reduction of grading score, and of pain, swallowing discomfort and quality of life was recorded. Discussion and conclusion: Results of this preliminary study are encouraging for the realization of larger studies focused on the application of LLLT protocols in management of radio-chemotreated patients with oral mucositis.

    A new, closed-system method to reduce air-, direct-, and incidental-contamination during therapeutic administration of oral I-131 was experimentally evaluated on twelve patients. We studied a standard control population using the routine practice of drinking the solution through a straw and compared results with our new technique. Various measurements were performed throughout all phases of dose administration to assess the relative difference of the two approaches. Using the closed system method before and during iodine administration revealed between 100 and 1000 times less activity per millimeter of air sample; whereas, the direct radiation exposure values were higher for the control population. Both the experimental and control methods had similar levels of incidental contamination

    Normalization of tumor blood vessels improves drug and oxygen delivery to cancer cells. The aim of this study was to develop a technique to normalize blood vessels in the hamster cheek pouch model of oral cancer. Materials and Methods: Tumor-bearing hamsters were treated with thalidomide and were compared with controls. Results: Twenty eight hours after treatment with thalidomide, the blood vessels of premalignant tissue observable in vivo became narrower and less tortuous than those of controls; Evans Blue Dye extravasation in tumor was significantly reduced (indicating a reduction in aberrant tumor vascular hyperpermeability that compromises blood flow), and tumor blood vessel morphology in histological sections, labeled for Factor VIII, revealed a significant reduction in compressive forces. These findings indicated blood vessel normalization with a window of 48 h. Conclusion: The technique developed herein has rendered the hamster oral cancer model amenable to research, with the potential benefit of vascular normalization in head and neck cancer therapy.

    The experimental gingivitis study of Löe et al.1 demonstrated a cause and effect relationship between plaque accumulation and gingival inflammation, and helped to establish plaque\\/biofilm as the primary risk factor for gingivitis. When healthy individuals withdrew oral hygiene efforts, gingival inflammation ensued within 21 days in all subjects. Once effective plaque removal was recommenced, clinical gingival health was quickly re-established – indicating that plaque-associated inflammation is modifiable by plaque control. As current consensus confirms that gingivitis and periodontitis may be viewed as a continuum of disease,2 the rationale for achieving effective plaque control is clear.

    Mucositis is a major complication in myeloablative therapy, which often necessitates advanced pharmacological pain treatment, including i.v. opioids. Attempts to prevent oral mucositis have included oral cryotherapy, which has been shown to reduce mucositis, but there is a lack of knowledge concerning the effect of oral cryotherapy on opioid use by reducing the mucositis for patients treated with myeloablative therapy before bone marrow transplantation (BMT). The aim of the present study was to evaluate if oral cryotherapy could delay or alleviate the development of mucositis and thereby reduce the number of days with i.v. opioids among patients who receive myeloablative therapy before BMT. Eighty patients 18 years and older, scheduled for BMT, were included consecutively and randomised to oral cryotherapy or standard oral care. A stratified randomisation was used with regard to type of transplantation. Intensity of pain, severity of mucositis and use of opioids were recorded using pain visual analogue scale (VAS) scores, mucositis index scores and medical and nursing charts. This study showed that patients receiving oral cryotherapy had less pronounced mucositis and significantly fewer days with i.v. opioids than the control group. In the autologous setting, cryotherapy patients also needed significantly lower total dose of opioids. Oral cryotherapy is an effective and well-tolerated therapy to alleviate mucositis and consequently reduce the number of days with i.v. opioids among patients treated with myeloablative therapy before BMT.

    Recently, the focus has been on the importance of assessing the oral disintegrative properties of orally disintegrating tablets (ODTs). In particular, in the development stages and the quality control field of ODT products, a physical assessment method which easily measures oral disintegrative properties is desired. For this reason, we developed a new disintegration test method (Kyoto-model disintegration method or KYO method), which is useful to predict the oral disintegrative properties of an ODT easily, and examined the availability of the method. In the KYO method, ODT samples were classified in terms of their water permeability, and a moderate water volume was decided. Subsequently, the disintegrative properties were assessed with the newly proposed method. For 25 commercial prescription ODTs used as samples, a good correlation was shown between the results of a human sensory test by five healthy male volunteers and the results using the KYO method. Furthermore, the KYO method could evaluate time-dependent changes in ODT samples. On the other hand, no correlation was observed between the Japanese Pharmacopeia disintegration test and the human sensory test. These results suggested that the KYO method reflected the disintegration nature of the ODTs in the oral cavity, and could easily be applied to development stages and the quality control field of ODT products.

    To review current literature on the effectiveness of oral rehydration therapy (ORT) in the treatment of mild to moderate dehydration in children. Recommendations from American Academy of Pediatrics (AAP), World Health Organization (WHO), selected research articles (2000-2006), and Internet sources. Dehydration is a common diagnosis in pediatric primary care. The literature indicates that dehydration is more often treated with intravenous (IV) therapy when ORT would be equally effective. ORT is an effective treatment for children with mild to moderate dehydration. ORT could be used more frequently rather than IV rehydration therapy. The use of ORT versus traditional methods of IV hydration matches the nursing philosophy of holistic care by enhancing client comfort and autonomy. Current practice in the treatment of mild to moderate dehydration in children does not match both AAP and WHO guidelines, which are based on evidence supporting ORT effectiveness. Treatment with ORT allows children more flexibility to be treated at home and thus decreases hospital stay. Evidence shows that the time required to initiate ORT is actually quicker than IV therapy and allows for a less stressful therapy that can be performed in the home.

    Our objective was to compare therapeutic outcome and analyse cost-benefit of a 'conventional' (7-day course of i.v. antibiotic therapy) vs. an abbreviated (2-day i.v. antibiotic course followed by 'switch' to oral antibiotics) therapy for in-patients with community-acquired pneumonia (CAP). We used a multicenter prospective, randomized, parallel group with a 28 day follow-up, at the University-based teaching hospitals: The Medical Center of Louisiana in New Orleans, LA and hospitals listed in the acknowledgement. Ninety-five patients were randomized to receive either a 'conventional' course of intravenous antibiotic therapy with cefamandole 1 g i.v. every 6 h for 7 days (n = 37), or an abbreviated course of intravenous therapy with cefamandole (1 g i.v. every 6 h for 2 days) followed by oral therapy with cefaclor (500 mg every 8 h for 5 days). No difference was found in the clinical courses, cure rates, survival or the resolution of the chest radiograph abnormalities among the two groups. The mean duration of therapy (6.88 days for the conventional group compared to 7-30 days for the early oral therapy group) and the frequencies of overall symptomatic improvement (97% vs. 95%, respectively) were similar in both groups. Patients who received early oral therapy had shorter hospital stays (7.3 vs. 9.71 days, P = 0.01), and a lower total cost of care ($2953 vs. $5002, P < 0.05). It was concluded that early transition to an oral antibiotic after an abbreviated course of intravenous therapy in CAP is substantially less expensive and has comparable efficacy to conventional intravenous therapy. Altering physicians' customary management of hospitalized patients with CAP can reduce costs with no appreciable additional risk of adverse patient outcome.

    High-dose intravenous thyroxine (T4) is the preferable treatment for myxedema coma. We describe the clinical course of a 69-year-old man who presented with myxedema coma and received oral levothyroxine (LT4) therapy (1 mg) in a split dose. This suggests split high-dose oral LT4 as a therapeutic option in myxedema coma.

    To some degree, acne vulgaris affects nearly every individual worldwide. Oral antibiotic therapy is routinely prescribed for the treatment of moderate to severe inflammatory acne; however, long-term use of oral antibiotics for acne may have unintended consequences. The aim of this study was to provide a systematic evaluation of the scientific evidence on the efficacy and appropriate use of oral antibiotics in the treatment of acne. A systematic search of MEDLINE was conducted to identify randomized controlled clinical trials, systematic reviews, and meta-analyses evaluating the efficacy of oral antibiotics for acne. Overall, 41 articles that examined oral antibiotics compared with placebo, another oral therapy, topical therapy, alternate dose, or duration were included in this study. Tetracyclines, macrolides, and trimethoprim/sulfamethoxazole are effective and safe in the treatment of moderate to severe inflammatory acne. Superior efficacy of one type or class of antibiotic could not be determined, therefore the choice of antibiotic is generally based on the side-effect profile. Although different dosing regimens have been studied, there is a lack of standardized comparator trials to determine optimal dosing and duration of each oral antibiotic used in acne. The combination of oral antibiotics with a topical therapy is superior to oral antibiotics alone. This article provides a systematic evaluation of the scientific evidence of the efficacy of oral antibiotics for acne. Due to heterogeneity in the design of the trials, there is insufficient evidence to support one type, dose, or duration of oral antibiotic over another in terms of efficacy; however, due to increasing resistance to antibiotics, dermatologists should heed consensus guidelines for their appropriate use.

    Full Text Available Abstract Background Oral lichen planus (OLP is seen frequently in patients with hepatitis C virus (HCV infection. The aim of this study was to evaluate the occurrence of oral candidiasis, other mucosal lesions, and xerostomia during interferon (IFN therapy for HCV infection. Methods Of 124 patients with HCV-infected liver diseases treated with IFN therapy in our hospital, 14 (mean age 56.00 ± 12.94 years who attended to receive administration of IFN once a week were identified and examined for Candida infection and other oral lesions and for the measurement of salivary flow. Serological assays also were carried out. Results Cultures of Candida from the tongue surfaces were positive in 7 (50.0% of the 14 patients with HCV infection at least once during IFN therapy. C. albicans was the most common species isolated. The incidence of Candida during treatment with IFN did not increase above that before treatment. Additional oral mucosal lesions were observed in 50.0% (7/14 of patients: OLP in three (21.4%, angular cheilitis in three (21.4% and recurrent aphthous stomatitis in one (7.1%. OLP occurred in one patient before treatment with IFN, in one during treatment and in one at the end of treatment. 85.7% of the oral lesions were treated with topical steroids. We compared the characteristics of the 7 patients in whom Candida was detected at least once during IFN therapy (group 1 and the 7 patients in whom Candida was not detected during IFN therapy (group 2. The prevalence of oral mucosal lesions (P=0.0075 and incidence of external use of steroids (P=0.0308 in group 1 were significantly higher than in group 2. The average body weight of group 1 decreased significantly compared to group 2 (P=0.0088. Salivary flow decreased in all subjects throughout the course of IFN treatment and returned at 6th months after the end of treatment. In group 1, the level of albumin at the beginning of the 6th month of IFN administration was lower than in group 2 (P=0

    SummaryHighly active antiretroviral therapy has decreased the morbidity and mortality related to HIV infection, including oral opportunistic infections. This paper offers an analysis of the scientific literature on the epidemiological aspects of oral candidiasis in HIV-positive children in the combination antiretroviral therapy era. An electronic databases search was made covering the highly active antiretroviral therapy era (1998 onwards). The terms used were oral lesions, oral candidiasis and their combination with highly active antiretroviral therapy and HIV/AIDS children. The following data were collected from each paper: year and country in which the investigation was conducted, antiretroviral treatment, oral candidiasis prevalence and diagnostic parameters (clinical or microbiological). Prevalence of oral candidiasis varied from 2.9% in American HIV-positive children undergoing highly active antiretroviral therapy to 88% in Chilean HIV-positive children without antiretroviral therapy. With respect to geographical location and antiretroviral treatment, higher oral candidiasis prevalence in HIV-positive children on combination antiretroviral therapy/antiretroviral therapy was reported in African children (79.1%) followed by 45.9% reported in Hindu children. In HIV-positive Chilean children on no antiretroviral therapy, high oral candidiasis prevalence was reported (88%) followed by Nigerian children (80%). Oral candidiasis is still frequent in HIV-positive children in the highly active antiretroviral therapy era irrespective of geographical location, race and use of antiretroviral therapy. © The Author(s) 2014.

    Purpose. To evaluate the efficacy and safety of endovascular therapy in oral hemorrhage from malignant head and neck tumors. Methods. Ten patients (mean age 56 years) with oral hemorrhage caused by malignant head and neck tumors underwent a total of 13 emergency embolization procedures using gelatin sponge particles, steel and/or platinum coils, or a combination of these embolic materials. Angiographic abnormalities, technical success rate, clinical success rate, recurrence rate, complications, hemostatic period, hospital days, survival days, and patient outcome were all analyzed. Results. Angiographic abnormalities were identified during 85% of procedures (11/13). The technical success rate was 100% (13/13 procedures). The primary and secondary clinical success rates were 77% (10/13 procedures) and 67% (2/3 procedures), respectively. The overall clinical success rate was 92%, and the recurrence rate was 22% (2/9 procedures) in patients whom we were able to observe during the 1-month period after embolization. No major complications occurred. Several patients in whom gelatin sponge particles had been used complained of transient local pain after the procedure. The median hemostatic period was 71 days (range 0-518 days). Median hospital and survival days were 59 days (range 3-209 days) and 141 days (range 4-518 days), respectively. Three patients survived and 7 patients died during the observation period. Only 1 of these 7 patients died from hemorrhage. Conclusion. In conclusion, our findings suggest that endovascular therapy is an effective, safe, and repeatable treatment for oral hemorrhage caused by malignant head and neck tumors

  14. Possible neuroimmunomodulation therapy in T-cell-mediated oral diseases

    Full Text Available Introduction: Recurrent aphthous stomatitis and oral lichen planus are local chronic inflammatory diseases which are implicated in T cell-mediated immunity. According to the systematic review, there is insufficient evidence to support any specific treatment for T-cell mediated oral diseases. The hypothesis: In this paper, we propose a hypothesis that recurrent aphthous stomatitis and oral lichen planus can be treated with selective α7 subunit of nicotinic acetylcholine receptor (α7 -nAChR agonists. Our hypothesis is supported by the following two facts. First, the pathophysiological conditions, T h 1/T h 17 cell activation and autonomic nervous system dysfunction, are observed in T-cell mediated oral diseases as well as in T-cell mediated systemic diseases such as rheumatoid arthritis. Second, the cholinergic anti-inflammatory pathway is inhibited in systemic T-cell mediated chronic inflammatory diseases. On the other hand, treatment with α7 -nAChR agonists which activate the cholinergic anti-inflammatory pathway suppresses neuroinflammation via inhibition of T h 1/T h 17 responses in animal model of systemic T-cell mediated chronic inflammatory diseases. We thus expect that selective α7 -nAChR agonists will be effective for the treatment of T-cell mediated oral diseases. Evaluation of the hypothesis: To test our hypothesis, we need to develop in vivo mouse model of T-cell mediated oral diseases. To evaluate the therapeutic effect of a selective α7 -nAChR agonist, we choose ABT-107 because of its safety and tolerability. We believe that the selective α7 -nAChR agonist, especially ABT-107, may be a therapeutic drug to treat T-cell mediated oral diseases.

OBJETIVO E MÉTODO: Através de revisão bibliográfica realizou-se atualizar informações quanto à definição, características clínicas, incidência, etiologia, patofisiologia, morbidade associada, prevenção e tratamento dessa manifestação clínica. RESULTADOS: Estudos atuais definem a mucosite bucal como uma inflamação e ulceração dolorosa bastante freqüente na mucosa bucal apresentando formação de pseudomembrana. Sua incidência e severidade são influenciadas por variáveis associadas ao paciente e ao tratamento a que ele é submetido. A mucosite é conseqüência de dois mecanismos maiores: toxicidade direta da terapêutica utilizada sobre a mucosa e mielossupressão gerada pelo tratamento. Sua patofisiologia é composta por quatro fases interdependentes: fase inflamatória/vascular, fase epitelial, fase ulcerativa/bacteriológica e fase de reparação. É considerada fonte potencial de infecções com risco de morte, sendo a principal causa de interrupção de tratamentos antineoplásicos. Algumas intervenções mostraram-se potencialmente efetivas para sua prevenção e tratamento. Entretanto, faz-se necessária a realização de novos estudos clínicos mais bem conduzidos para obtenção de melhor evidência científica acerca do agente terapêutico de escolha para o controle da mucosite bucal, permitindo a realização da quimioterapia e radioterapia do câncer em parâmetros ideais.Tincreasing the intensity of radiation therapy and chemotherapy in the management of cancer has increased the incidence of adverse effects, especially oral mucositis.

    In radiation therapy of cancer of the oral cavity and the paranasal sinuses, the extent to which the tissues of the oral cavity are included in the radiation treatment portals will determine the severity of the oral discomfort during treatment. This will affect the nutritional status of the patients, and may eventually affect the total dose of radiation which the patients can receive for treatment of their cancers. In cooperation with the Maxillofacial Prosthetic Department, an acrylic resin oral prosthesis was developed. This prosthesis is easy to use and can be made for each individual patient within 24 hours. It allows for maximum sparing of the normal tissues in the oral cavity and can be modified for shielding of backscattered electrons from heavy metals in the teeth. We have also found that acrylic resin extensions can be built onto the posterior edge of post-maxillectomy obturators; this extension can be used as a carrier for radioactive sources to deliver radiation to deep seated tumor modules in the paranasal sinuses.

    1990-01-01

    No part of the body reflects the complications of cancer chemotherapy as visibly and as vividly as the mouth. The infectious, hemorrhagic, cytotoxic, nutritional, and neurologic signs of drug toxicity are reflected in the mouth by changes in the color, character, comfort, and continuity of the mucosa. The stomatologic complications of radiotherapy for oral cancer are physical and physiological in nature, transient or lasting in duration, and reversible or irreversible in type. Some linger as permanent mementos long after the cancer has been destroyed. They stem from radiation injury to the salivary glands, oral mucosa, oral musculature, alveolar bone, and developing teeth. They are expressed clinically by xerostomia, trismus, radiation dermatitis, nutritional stomatitis, and dentofacial malformation. In both cancer chemotherapy and cancer radiotherapy, the oral complications vary in pattern, duration, intensity, and number, with not every patient developing every complication. 21 references

    Surgery for carcinoma of the oral cavity has developed rapidly with recent advances in reconstruction. Particularly, in radical surgery for progressive and recurrent disease, safe and adequate resection has been made possible and postoperative cosmetic and functional recovery has been achieved. We reviewed 64 patients with progressive and recurrent cancer who had undergone reconstruction using microvascular techniques during the 12 years from 1983 to 1994. There were 19 patients with T3 disease, 25 with T4 disease, and 20 with recurrence. The free grafts used were radial forearm flaps, the jejunum, rectus abdominis musculocutaneous flaps, and scapular flaps. The survival of free flap grafts was 95.3%. The primary tumor control rate was 85.9%, and the 5-year cumulative survival rate was 61.1%, 60.1%, and 62.9% for patients with T3, T4, and recurrent disease, respectively. Twelve patients with T4 disease of the tongue and the floor of the mouth were treated with combined preoperative brachytherapy and surgery to alleviate postoperative dysfunction, and this treatment was found to be exceedingly effective for improving the postoperative quality of life. There are still many problems with mandibular reconstruction. Since cancer patients commonly undergo preoperative radiotherapy, transplantation of living vascularized bone grafts is frequently performed and is believed to be effective. Since it is important to reconstruct masticatory function as well as to achieve cosmetic improvement, various techniques have recently been used to fit the reconstructed mandible with dental prostheses in order to restore masticatory function. This paper describes the present status and the prospects of surgical therapy for oral cancer. (author)

    Full Text Available Patological disorders within oral mucosa (so called mucositis are the most common stomatological complications among chemotherapy treated leukemic patients scheduled for bone marrow transplantation. Early diagnosis of such oral disorders leads to numerous side effects, decreasing quality of life and systemic complications is required. Furthermore, most patients require analgesic treatment, very often using narcotic pain medications. Presently the largest role of prevention and treatment of mucositis is preventative dentistry along with maintaining strict oral hygiene. This course of action aims to reduce pain and prevention of infections. Investigation of novel non-invasive therapeutic methods that could improve treatment outcomes seems justified. Among the most promising methods, the Low-level Laser Therapy (LLLT treatment demonstrates many beneficial effects for patients suffering from chemotherapy complications. It promotes mucosal healing and helps improve patients' quality of life. These advantages may be a result of a LLLT anti-inflammatory and analgesic effect. LLLT also promotes tissue regeneration through chemical changes in cells (cell repair. In recent clinical studies conducted on a group of patients with oral mucositis, the significant acceleration of mentioned disorders regression was noted. Moreover, reduction of pain after application of LLLT was recorded. Discussed in the article LLLT is easily accessible for clinical practice . Mentioned arguments justify a wider use of such a tool in non-invasive treatment of acute oral cavity inflammation.

Because many newer therapeutic agents are oral and self-administered by the patient, adherence is a concern. The purpose of our analysis was to explore relationships between adherence, patient characteristics, and barriers to adherence.Methods: This secondary analysis utilized self-reported data from a randomized trial of self-care management conducted at two cancer centers in the US. Symptom distress was measured using the 15-item Symptom Distress Scale (SDS-15 and depression with the Patient Health Questionnaire-9 (PHQ-9. Adherence to oral medication was self-reported using the 8-item Morisky Medication Adherence Scale (MMAS-8. Measures were collected via Web-based, study-specific software ~8 weeks after treatment start date. Odds of low/medium adherence (score <8 were explored using univariate logistic regression. Given the number of factors and possible relationships among factors, a classification tree was built in lieu of a multivariable logistic regression model.Results: Of the eligible participants enrolled, 77 were on oral therapy and 70 had an MMAS score. Forty-nine (70% reported a high adherence score (=8. Higher odds of low/medium adherence were associated with greater symptom distress (P=0.09, more depression (P=0.05, chemotherapy vs hormonal oral medication (P=0.03, being female (P=0.02, and being randomized to the control group in the parent trial (P=0.09.

To evaluate an intensive protocol aimed at reducing gingivitis in pregnant women and provide pilot data for large-scale randomized controlled trials investigating oral hygiene measures to reduce pregnancy gingivitis and alter maternity outcomes. One hundred and twenty participants between 16 and 24 weeks gestation with Gingival Index (GI) scores ≥2 at ≥50% of tooth sites were enrolled. Plaque index (PI), gingival inflammation (GI), probing depth (PD), and clinical attachment levels (CAL) were recorded at baseline and 8 weeks. Dental prophylaxis was performed at baseline and oral hygiene instructions at baseline, 4 and 8 weeks. Pregnancy outcomes were recorded at parturition. Mixed-model analysis of variance was used to compare clinical measurements at baseline and 8 weeks. Statistically significant reductions in PI, GI, PD, and CAL occurred over the study period. Mean whole mouth PI and GI scores decreased approximately 50% and the percentage of sites with PI and GI ≥2 decreased from 40% to 17% and 53% to 21.8%, respectively. Mean decreases in whole mouth PD and CAL of 0.45 and 0.24 mm, respectively, were seen. Intensive oral hygiene regimen decreased gingivitis in pregnant patients. © 2013 John Wiley & Sons A/S.

    This study evaluated the efficacy of combined (intra- and extraoral) low-level laser therapy (LLLT) and conventional pharmacological modalities in prevention and treatment of oral mucositis (OM) and associated pain and xerostomia in patients with head and neck cancer (HNC) undergoing concurrent chemoradiotherapy (CRT). A prospective comparative randomized study was conducted with 21 patients with head and neck cancer subjected to CRT. Eleven patients received extra- and intraoral LLLT daily from the 1st day until the end of CRT-course before each session during 5 consecutive days, and the other 10 patients received conventional preventive and treatment procedures based on the use of benzidamine 0.15% solution also throughout the duration of CRT, including weekends. OM was measured using an oral toxicity scale (OTS), oral pain was measured using the color-numeric visual analogue scale (VAS), unstimulated salivary flow rate measured by the spitting technique (ml/min), dry mouth symptoms were self-estimated by patients using The Xerostomia Inventory (XI). The LLLT group showed lower mean OTS and VAS scores, lower level of reduction of salivary flow rate during the course of CRT. In both groups, no interruption of CRT was needed. The prophylactic use of both treatments proposed in this study seems to reduce the incidence of severe OM lesions. However, the LLLT was more effective in delaying the appearance of severe OM, oral pain and xerostomia.

    Music therapists have an ethical and professional responsibility to provide the highest quality care possible to their patients. Much of the time, high quality care is guided by evidence-based practice standards that integrate the most current, available research in making decisions. Accordingly, music therapists need research that integrates multiple ways of knowing and forms of evidence. Mixed methods research holds great promise for facilitating such integration. At this time, there have not been any methodological articles published on mixed methods research in music therapy. The purpose of this article is to introduce mixed methods research as an approach to address research questions relevant to music therapy practice. This article describes the core characteristics of mixed methods research, considers paradigmatic issues related to this research approach, articulates major challenges in conducting mixed methods research, illustrates four basic designs, and provides criteria for evaluating the quality of mixed methods articles using examples of mixed methods research from the music therapy literature. Mixed methods research offers unique opportunities for strengthening the evidence base in music therapy. Recommendations are provided to ensure rigorous implementation of this research approach.

    Full Text Available Objectives: (i To assess reduction in Streptococcus mutans and Lactobacillus species count in saliva sample after ten minutes of oil gum massage therapy (massage of gingival tissues per day for three weeks with sesame oil, olive oil, and coconut oil in three different groups of subjects. (ii To compare the efficacy between three different oils and the "gold standard" chlorhexidine gel. (iii To assess reduction in gingival scores and plaque scores of study subjects. Materials and Methods: Study design - Single center, parallel design, and triple blind randomized clinical study with four treatment groups. Participants: 32 of the 40 study subjects working as housekeeping personnel at Kasturba Hospital, Manipal; aged 18-55 years completed the three-week study period. Interventions: Subjects were randomly assigned to massage their gingiva everyday for three weeks with sesame oil, olive oil, coconut oil (tests, and Chlorhexidine gel (control. Oral health status and paraffin stimulated saliva samples were obtained at baseline and after three weeks of oil gum massage therapy. Outcome measures: Microbial culture, plaque index, and gingival index. Statistical analysis: Paired t test and Kruskal Wallis test. Results: There was a significant reduction in mean Streptococcus mutans count, Lactobacillus count, plaque scores, and gingival scores in all four groups after the study. However, there was no significant difference found in percentage reduction of these variables between the four groups. Conclusion: These oils can be used as valuable preventive agents in maintaining and improving oral health in low socioeconomic status population. However, it is recommended that further research should be conducted in other populations with a larger sample and longer duration of follow-up period.

    Full Text Available Background: Oral anticoagulation treatment (OAT such as warfarin therapy is recommended for older adults with atrial fibrillation, heart failure, or who are at risk for venous thromboembolism. Despite its proven benefits, older adults report both dissatisfaction with OAT and reduced quality of life that can potentially lead to low adherence to OAT and decreased treatment efficacy. Objective: To test the feasibility of Mobile Applications for Seniors to enhance Safe anticoagulation therapy (MASS, a mobile-based health technology intervention designed to promote independence and self-care. Method s: This pilot study used a single-arm experimental pre–post design to test the feasibility of a 3-month intervention using MASS in 18 older adults (male: n = 14; White: n = 9; Hispanic: n = 7; Other: n = 2; M age = 67. MASS was available in English or Spanish. Participants completed surveys about their OAT knowledge, attitudes, quality of life with OAT, and adherence at baseline and at a 3-month follow-up. Satisfaction with the MASS intervention was also assessed at follow-up. Results: Anticoagulation knowledge significantly improved from baseline to follow-up ( M base = 12.5 ± 5.51, M follow-up = 14.78 ± 3.93, p = .007. Other outcomes were not different, pre- and post-tests. Participants reported they were generally satisfied with MASS, its ease of use and its usefulness. Conclusion: The results showed use of MASS improved older adults’ knowledge of OAT. Using mHealth apps may enhance self-care among older adults with chronic conditions who are also taking oral anticoagulants.

    To investigate oral candidiasis in patients with head and neck cancer before, during, and after radiation therapy, and to explore its association with clinical oropharyngeal symptoms. A cohort study. University hospital. Subjects who received radiation therapy (RT) for the treatment of head and neck cancer were divided into two groups: an oral cavity irradiated group (OIRR group, n = 29) and an oral cavity nonirradiated group (ONIRR group, n = 17). A control group consisted of 18 healthy subjects. Patients were examined for signs of oral candidiasis before, during, immediately after, and one month after RT. Mouth and throat soreness (MTS), dysphagia, and xerostomia were evaluated by self-reported questionnaires, and associations between oral candidiasis and these symptoms were analyzed. The incidence of oral candidiasis during RT was significantly higher in the OIRR group (55.2%) than in the ONIRR group (11.8%). Similarly, the occurrence of xerostomia during RT was significantly higher in the OIRR group (86.2%) than in the ONIRR group (52.9%). In the OIRR group, the mean MTS score at the 20th fraction of RT was significantly higher in patients with candidiasis (mean +/- SD, 5.8 +/- 2.1) than in those with RT-induced mucositis without candidiasis (3.7 +/- 2.0). In the OIRR group, 65.2 percent of patients who experienced dysphagia developed oral candidiasis, compared with only 10 percent in the ONIRR group. Oral candidiasis concurrent with oral mucositis due to RT may increase oropharyngeal discomfort during RT. Copyright (c) 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

    The objectives of this study was to examine the effectiveness of Cepharanthin (Kakensyoyaku, Tokyo, Japan) at decreasing side effects during radiation therapy for oral cancer and thereby allowing the completion of radiation therapy without interruption. Two hundred fifteen patients diagnosed with oral cancers were assigned to either Cepharanthin or control groups and underwent external beam irradiation. The completion of the course of radiation therapy and the occurrence of side effects such as mucositis, dysgeusia, and xerostomia during the radiation therapy were evaluated and compared. The completion rate was 87.4% for the Cepharanthin group versus 67.0% for the control group, and the difference was statistically significant (P<0.01). Mucositis did not appear in 58 of 127 cases (45.7%) in the Cepharanthin group or in 21 of 88 cases (23.9%) in the control group. Mucositis developed in 24.6% of the Cepharanthin group and 53.7% of the control group within 2 weeks of irradiation. There were significant relationships between the use of Cepharanthin and the development and timing of mucositis (both P<0.01). Cepharanthin improved the completion of radiation therapy without interruption and reduced or delayed the development of mucositis during radiation therapy for oral cancer. (author)

    Ozone is highly valued for various therapeutic applications such as antimicrobial, antihypoxic, analgesic, and immunostimulating for more than a century in the medical profession. Ozone therapy is now gaining a strong foothold in dentistry. Ozone has bactericidal, fungicidal, and virucidal properties. Oral candidiasis is one of the most common opportunistic fungal infections of the oral cavity. Hence, a study was conducted to evaluate and compare the ability of ozonated water and topical clotrimazole in reducing the Candidal species colony-forming unit (CFU) count in oral candidiasis. The study included 40 candidiasis patients of either sex aged between 18 and 60 years attending the Department of Oral Medicine and Radiology. The patients were randomly assigned to either topical ozone therapy or topical clotrimazole groups. Salivary Candidal CFU counts were assessed during and after the treatments. There was gradual but significant reduction in Candidal CFU count in both groups. At the end of the treatment, Candidal CFU count reduction in ozone group (60.5% reduction) was more than the clotrimazole group (32.3% reduction). 14 patients (70%) with candidiasis in ozone group were reduced to 6 (30%) whereas only 8 patients (40%) out of 13 (65%) in clotrimazole group, although intergroup comparison was not statistically significant. Ozone therapy was much more effective in reducing the patients with candidiasis to a state of carriers. These findings suggest that ozonated water might be useful to treat oral candidiasis.

    Full Text Available Introduction: The human immunodeficiency virus (HIV acquired immunodeficiency syndrome disease has evolved to become a social and economic catastrophe, with far-reaching implications affecting every phase of life of the diseased individual. Data on adults and children diagnosed with HIV infection are useful for determining populations needing prevention and treatment services. Oral lesions may be the presenting symptoms of HIV infection and may differ entirely from those manifested in the adult population. Aim and Objective: We aimed to evaluate the prevalence of HIV related oral lesions among pediatric HIV patients and to assess the oral health status of HIV infected children residing in a selected childcare facility in Puducherry. Materials and Methods: A cross-sectional study was conducted during September 2015 in child care facility for HIV infected children located in Puducherry U.T, India. All children <18 years, who are diagnosed with HIV infection and are put on anti-retroviral therapy (ART or pre-ART care, were included in the study. After obtaining informed consent from the care-givers and assent of the children, they were interviewed and examined by a team comprising a qualified dental surgeon and a trained physician. Results: Majority of the children were under first-line ART (73% and were on ART for more than 4 years. The CD4 count of 23 (52.3 was between 500–1000 cells/μL. The recent viral load assay in 32 (72.7 patients was <150/not detected. Tooth decay was the most common oral manifestation with 28 (63.6 being affected. Nonspecific lymphadenopathy 26 (59.1 was the most common coexisting systemic illness. Conclusion: This study proves that constant surveillance by monitoring the general health status, CD4 counts, viral load coupled with stringent ART care has improved the overall quality of life of these children and consequently resulted in lesser oral manifestations.

    Purpose: To estimate the effect of fasting during Ramadan (the ninth lunar month) on adherence to oral hormonal therapies (OHT) among breast cancer (BC) patients. Patients and Methods: During Ramadan 2010, 139 BC patients were interviewed at the Egyptian National Cancer Institute. They were asked about fasting as well as intake of OHT in Ramadan and in the preceding month. Results: The median age was 50 years and most patients were postmenopausal with good performance status and non-metastatic disease. The median number of fasting days was 18% and 93% of patients were fasting 80% or more of Ramadan. Tamoxifen and aromatase inhibitors were used in 64% and 36%, respectively. Adherence to OHT during Ramadan and its preceding month were 94.2% and 95.7%, respectively (p = 0.77). In univariate analysis, non-adherence prior to Ramadan and shorter duration of OHT were predictors of non-adherence during Ramadan (P < 0.001, 0.003, respectively). Fasting, age, performance status, presence of metastases and type of hormonal therapy were not good predictors of adherence. Conclusions: While most of patients receiving OHT for BC are fasting during Ramadan, this does not negatively impact compliance with treatment

    The oral mucositis is a main side effect of radiotherapy on head and neck, initiating two weeks after the beginning of the treatment. It is characterized by sensation of local burning to intense pain, leading in several cases, to the interruption of the treatment. The purpose of this work is to review the main published studies that discuss the clinical, biological and histopathological features of oral mucositis induced by radiation therapy and to describe the main approaches recommended to prevent or to treat it. Although the clinical features of mucositis are intensively described in the literature, few studies address the histopathological alterations in oral mucositis and only recently, its biological processes have been investigated. The biological mechanisms involved in the radiation tissue damage have been only recently discussed and there is no consensus among treatment modalities. Yet, the progressive knowledge in the histopathology and biological characteristics of oral mucositis probably will lead to more effective in prevention and control strategies. (author)

    This study compared the effectiveness of different methods of instruction for the oral and pharyngeal cancer examination. A group of thirty sophomore students at the University of Florida College of Dentistry were randomly assigned to three training groups: video instruction, a faculty-led hands-on instruction, or both video and hands-on instruction. The training intervention involved attending two sessions spaced two weeks apart. The first session used a pretest to assess students' baseline didactic knowledge and clinical examination technique. The second session utilized two posttests to assess the comparative effectiveness of the training methods on didactic knowledge and clinical technique. The key findings were that students performed the clinical examination significantly better with the combination of video and faculty-led hands-on instruction (p<0.01). All students improved their clinical exam skills, knowledge, and confidence in performing the oral and pharyngeal cancer examination independent of which training group they were assigned. Utilizing both video and interactive practice promoted greater performance of the clinical technique on the oral and pharyngeal cancer examination.

    The incidence of recurrent tinea infections after oral terbinafine therapy is on the rise. This study aims to identify the appearance of incomplete cure and relapse after 2-week oral terbinafine therapy in tinea corporis and/or tinea cruris. A total of 100 consecutive patients clinically and mycologically diagnosed to have tinea corporis and/or tinea cruris were included in the study. The enrolled patients were administered oral terbinafine 250 mg once daily for 2 weeks. All clinically cured patients were then followed up for 12 weeks to look for any relapse/cure. The common dermatophytes grown on culture were Trichophyton rubrum and Trichophyton tonsurans in 55% and 20% patients, respectively. At the end of 2-week oral terbinafine therapy, 30% patients showed a persistent disease on clinical examination while 35% patients showed a persistent positive fungal culture (persisters) at this time. These culture positive patients included all the clinically positive cases. Rest of the patients (65/100) demonstrated both clinical and mycological cure at this time (cured). Over the 12-week follow-up, clinical relapse was seen in 22 more patients (relapse) among those who had shown clinical and mycological cure at the end of terbinafine therapy. Thus, only 43% patients could achieve a long-term clinical and mycological cure after 2 weeks of oral terbinafine treatment. Majority of the relapses (16/22) were seen after 8 weeks of completion of treatment. There was no statistically significant difference in the body surface area involvement or the causative organism involved between the cured, persister, or relapse groups. Incomplete mycological cure as well as relapse is very common after standard (2-week) terbinafine therapy in our patients of tinea cruris/corporis.

    Full Text Available Introduction: Acute myeloid leukemia (AML in elderly patients differs biologically from that in younger patients and is known to have unfavorable chromosomal rearrangements, higher resistance, and lower tolerance to chemotherapy. In such circumstances, instead of giving full-blown chemotherapy, palliative metronomic chemotherapy (MCT could be a treatment option. Patients and Methods: We performed a prospective pilot study of old AML patients (age >60 years not amenable to curative treatment. Thirty-two patients were enrolled into the study and were treated with daily oral 6-mercaptopurine 75 mg/m 2 . The following inclusion criteria were used: age >60 years, nonpromyelocytic AML, the absence of uncontrolled comorbidities, and patient not amenable to curative treatment. Overall survival (OS was calculated using Kaplan-Meier method and Cox regression analysis were used to calculate the hazards ratio of significant factors. Results: The median age of the patients was 69 years (range: 61-86 years with male: female ratio of 2.5:1. About 59.4% of patients had Eastern Cooperative Oncology Group performance status of 2 while rest had the status of 3. The median OS was 6 months (95% confidence interval [CI]: 4.4-7.6. Males had median OS of 7 months (95% CI: 5.4-8.6 versus females with OS of 3 months (95% CI: 1.5-4.4; P = 0.008. There was no survival difference on the basis of baseline hemoglobin or French-American-British class. There were no Grade 4 toxicities and no episode of febrile neutropenia. Conclusions: MCT with oral 6-mercaptopurine is an attractive treatment option in elderly AML patients who are not amenable to curative therapy with minimal toxicities.

    This retrospective study in 39 dogs with incompletely resected oral melanoma examined the efficacy of hypofractionated radiation therapy and platinum-containing chemotherapy. All dogs were completely staged, with the majority of dogs classified as stage 1. Dogs received 6 weekly fractions of 6-gray (Gy) megavoltage irradiation with a cobalt-60 unit or a 4-MeV (megaelectron volts) linear accelerator. Dogs received cisplatin (10-30 mg/m2 IV) or carboplatin (90 mg/m2 IV) chemotherapy 60 minutes before radiation delivery. Durations of local control, metastasis-free survival time, and overall survival time were recorded. By the Kaplan-Meier method, 15% of the dogs had local recurrence within a median time of 139 days. Fifty-one percent of the dogs developed metastatic disease within a median time of 311 days (range, 24-2, 163 days). Median survival time for all 39 dogs was 363 days. The combined use of chemotherapy and radiation therapy in this protocol provided local control consistent with previous studies. Low-dose chemotherapy was used with the intent of enhancing radiation therapy for the local control of an incompletely excised tumor. Survival times were longer than previously reported for dogs with oral malignant melanoma. Additional studies are required to determine whether these results were due to the effects of chemotherapy on microscopic disease or the enhanced local control provided by chemoradiation therapy.

    Functional cerebral asymmetries (FCAs) are known to fluctuate across the menstrual cycle. The visual line-bisection task administered to normally cycling women showed different patterns of the interhemispheric interactions during menses and the midluteal cycle phase. However, the contribution of estrogens and progestins hormones to this phenomenon is still unclear. The aim of our study was to show a variation of FCAs in women administered oral contraceptives (OCs) using the visual line-bisection task. Visual line-bisection task with three horizontal lines was administered to 36 healthy women taking a 21-day OC. Twenty-nine patients were right handed. The task was administered during OC intake (day 10) and at the end of the pill-free period. The right-handed women showed a significant leftward bias of veridical center on the first and third lines during OC intake compared with an opposite rightward bias during the pill-free period. The same phenomenon of contralateral deviation was observed in left-handed women on day 10 of OC intake. The results of this study confirm a hormonal modulation on interhemispheric interaction and suggest that OCs may improve the interhemispheric interaction reducing FCAs compared with the low hormone level period. This opens new insights in OC prescription and choice of administration schedule in order to improve cognitive performances. Copyright © 2011 Elsevier Inc. All rights reserved.

  12. Oral Tolerance: A New Tool for the Treatment of Gastrointestinal Inflammatory Disorders and Liver-Directed Gene Therapy

    Full Text Available Oral tolerance is a method of downregulating an immune response by feeding antigens. The use of oral tolerance toward adenoviruses and colitis-extracted proteins for long term gene therapy and alleviation of experimental colitis, and the mechanisms of tolerance induction are presented. Adenoviruses are efficient vectors in liver-directed gene therapy; however, the antiviral immune response precludes the ability to achieve long term gene expression and prohibits the ability to reinject the recombinant virus. Oral tolerance induction via feeding of viral-extracted proteins prevented the antiadenoviral humoral and cellular immune responses, thus enabling long term gene therapy using these viruses. Moreover, pre-existing immune response to the virus was overcome by tolerance induction, enabling prolonged gene expression in a presensitized host. Inflammatory bowel diseases are immune-mediated disorders where an imbalance between proinflammatory (T helper cell type 1 and anti-inflammatory (T helper cell type 2 cytokines are thought to play a role in the pathogenesis. In the experimental colitis model, the feeding of colitis-extracted proteins downregulated the anticolon immune response. Tolerance induction toward colitis-extracted proteins ameliorated colonic inflammation as shown by decreased diarrhea and reduction of colonic ulcerations, intestinal and peritoneal adhesions, wall thickness and edema. Histological parameters for colitis were markedly improved in tolerized animals. In both models, tolerized animals developed an increase in transforming growth factor-beta, interleukin-4 and interleukin-10, and a decrease in the mRNA of interferon-gamma lymphocytes and serum levels. Adoptive transfer of tolerized lymphocytes enabled the transfer of tolerance toward adenoviruses and colon-extracted proteins. Thus, oral tolerance induces suppressor lymphocytes that mediate immune response downregulation by induction of a shift from a proinflammatory T

    Candida albicans is a minor component of the oral microbiota and an opportunistic pathogen that takes advantage of the immunocompromised host and causes oral mucositis and oral candidiasis. This organism is able to undergo phenotypic modification from a yeast to hyphae growth phase, one of the key arsenals for immune cell evasion, tissue invasion and biofilm formation. The latter property coupled with overgrowth and immune compromising factors such as HIV/AIDS, cancer treatments, organ transplantation, diabetes, corticosteroid use, dentures, and broad-spectrum antibiotic use have modified the fungus from a normal component of the microflora to a foe of an oral cavity and resulting in reduced sensitivity towards commonly utilised antifungal agents. Hence, the need for alternative therapy to curb this plight is of importance. Making use of biomolecules produced by Streptococcus mutans, application of lactoferrin which is a nonspecific host defense factor found in saliva with metal chelating and broader antimicrobial properties, use of probiotics which have the capacity to boost the host immunity through eliciting Immunoglobulin A synthesis, and perturbing the pathogen's environment via competition of space and food, and application of photodynamic therapy can help to manage the burden of oral candidiasis.

    2013-12-01

    Full Text Available This paper addresses the concept and use of the instrument named ‘activities’ in occupational therapy, sustained by the propositions of the Dynamic Occupational Therapy Method (DOTM. Initially, we present general aspects related to the activities in the DOTM such as the option for the name ‘activities’, its conceptual definition, use as a tool, and active participation in the dynamic of triadic relationship. Further, it approaches the character of activities: therapeutic, educational and social qualities, which distinguish this peculiar occupational therapy. Moreover, the paper highlights the use of activities as a tool, both as a central element of the processes that should underpin clinical reasoning (observation, information, association, setting up space of historicity, and construction of narrative, and as an element belonging to diagnostic procedures, to the course of clinical process, and to evaluation. Finally, we present our understanding of what we call resources in DOTM, and its intrinsic connection with the possibility of performing ‘activities’. For the creation of DOTM, occupational therapy, as a practice focused on the uniqueness of the case, was made the object of study in order to promote knowledge construction. The conceptual and instrumental framework presented in this work held this effort. We hope that this study could be useful for initial and continuing training in Occupational Therapy as well as for enriching the debate on the use of ‘activities’ in our profession.

  15. Effects of Long Term Antibiotic Therapy on Human Oral and Fecal Viromes.

    Viruses are integral members of the human microbiome. Many of the viruses comprising the human virome have been identified as bacteriophage, and little is known about how they respond to perturbations within the human ecosystem. The intimate association of phage with their cellular hosts suggests their communities may change in response to shifts in bacterial community membership. Alterations to human bacterial biota can result in human disease including a reduction in the host's resilience to pathogens. Here we report the ecology of oral and fecal viral communities and their responses to long-term antibiotic therapy in a cohort of human subjects. We found significant differences between the viral communities of each body site with a more heterogeneous fecal virus community compared with viruses in saliva. We measured the relative diversity of viruses, and found that the oral viromes were significantly more diverse than fecal viromes. There were characteristic changes in the membership of oral and fecal bacterial communities in response to antibiotics, but changes in fecal viral communities were less distinguishing. In the oral cavity, an abundance of papillomaviruses found in subjects on antibiotics suggests an association between antibiotics and papillomavirus production. Despite the abundance of papillomaviruses identified, in neither the oral nor the fecal viromes did antibiotic therapy have any significant impact upon overall viral diversity. There was, however, an apparent expansion of the reservoir of genes putatively involved in resistance to numerous classes of antibiotics in fecal viromes that was not paralleled in oral viromes. The emergence of antibiotic resistance in fecal viromes in response to long-term antibiotic therapy in humans suggests that viruses play an important role in the resilience of human microbial communities to antibiotic disturbances.

    The aim of this study was to evaluate the frequency of Candida species and presence of lesions in the oral cavity of patients with sickle cell anemia (SS). The study included 30 patients diagnosed with sickle cell anemia and taking hydroxyurea for at least 90 days (SS/HU+); and 39 patients with sickle cell anemia and without hydroxyurea therapy (SS/HU-). Two control groups were constituted by healthy individuals matched to the test groups in age, gender, and oral conditions (C/HU+ for SS/HU+ and C/HU- for SS/HU-). Oral clinical examination and anamnesis were performed. Yeasts were collected by oral rinses and identified by API system. Antifungal susceptibility evaluation was performed according to the CLSI methodology. Data obtained for microorganisms counts were compared by Student's t test (SS/HU+ vs. C/HU+ and SS/HU- vs. C/HU-) using MINITAB for Windows 1.4. Significance level was set at 5%. No oral candidosis lesions were detected. Significant differences in yeasts counts were observed between SS/HU- group and the respective control, but there were no differences between SS/HU+ and C/HU+. Candida albicans was the most prevalent species in all groups. Candida famata was observed both in SS and control groups. Candida dubliniensis, Candida glabrata, Candida krusei, Candida tropicalis, Candida pelliculosa, and Candida parapsilosis were observed only in SS groups. Most strains were susceptible to all antifungal agents. Hydroxyurea therapy seems to decrease candidal counts and resistance rate in sickle cell anemia patients. However, further studies should be conducted in the future to confirm this finding. Hydroxyurea therapy in sickle cell anemia patients maintains fungal species balance in oral cavity. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    There is paucity of data evaluating intravenous-to-oral antibiotic switch options for Gram-negative bloodstream infections (BSIs). This retrospective cohort study examined the effectiveness of oral antibiotics for definitive treatment of Gram-negative BSI. Patients with Gram-negative BSI hospitalised for antibiotics were included in this study. The cohort was stratified into three groups based on bioavailability of oral antibiotics prescribed (high, ≥95%; moderate, 75-94%; and low, antibiotics were prescribed to 106, 179 and 77 patients, respectively, for definitive therapy of Gram-negative BSI. Mean patient age was 63 years, 217 (59.9%) were women and 254 (70.2%) had a urinary source of infection. Treatment failure rates were 2%, 12% and 14% in patients receiving oral antibiotics with high, moderate and low bioavailability, respectively (P = 0.02). Risk of treatment failure in the multivariate Cox model was higher in patients receiving antibiotics with moderate [adjusted hazard ratio (aHR) = 5.9, 95% CI 1.6-38.5; P = 0.005] and low bioavailability (aHR = 7.7, 95% CI 1.9-51.5; P = 0.003) compared with those receiving oral antimicrobial agents with high bioavailability. These data demonstrate the effectiveness of oral antibiotics with high bioavailability for definitive therapy of Gram-negative BSI. Risk of treatment failure increases as bioavailability of the oral regimen declines. Copyright © 2016 Elsevier B.V. and International Society of Chemotherapy. All rights reserved.

    11 children with either cystinosis or Lowe's syndrome had a reduced content of plasma and muscle carnitine due to renal Fanconi syndrome. After treatment with oral L-carnitine, 100 mg/kg per d divided every 6 h, plasma carnitine concentrations became normal in all subjects within 2 d. Initial plasma free fatty acid concentrations, inversely related to free carnitine concentrations, were reduced after 7-20 mo of carnitine therapy. Muscle lipid accumulation, which varied directly with duration of carnitine deficiency (r = 0.73), improved significantly in three of seven rebiopsied patients after carnitine therapy. One Lowe's syndrome patient achieved a normal muscle carnitine level after therapy. Muscle carnitine levels remained low in all cystinosis patients, even though cystinotic muscle cells in culture took up L-[ 3 H]carnitine normally. The half-life of plasma carnitine for cystinotic children given a single oral dose approximated 6.3 h; 14% of ingested L-carnitine was excreted within 24 h. Studies in a uremic patient with cystinosis showed that her plasma carnitine was in equilibrium with some larger compartment and may have been maintained by release of carnitine from the muscle during dialysis. Because oral L-carnitine corrects plasma carnitine deficiency, lowers plasma free fatty acid concentrations, and reverses muscle lipid accumulation in some patients, its use as therapy in renal Fanconi syndrome should be considered. However, its efficacy in restoring muscle carnitine to normal, and the optimal dosage regimen, have yet to be determined

    Oral cancer is a global health burden with significantly poor survival, especially when the diagnosis is at its late stage. Despite advances in current treatment modalities, there has been minimal improvement in survival rates over the last five decades. The development of local recurrence, regional failure, and the formation of second primary tumors accounts for this poor outcome. For survivors, cosmetic and functional compromises resulting from treatment are often devastating. These statistics underscore the need for novel approaches in the management of this deadly disease. Photodynamic therapy (PDT) is a treatment modality that involves administration of a light-sensitive drug, known as a photosensitizer, followed by light irradiation of an appropriate wavelength that corresponds to an absorbance band of the sensitizer. In the presence of tissue oxygen, cytotoxic free radicals that are produced cause direct tumor cell death, damage to the microvasculature, and induction of inflammatory reactions at the target sites. PDT offers a prospective new approach in controlling this disease at its various stages either as a stand-alone therapy for early lesions or as an adjuvant therapy for advanced cases. In this review, we aim to explore the applications of PDT in oral cancer therapy and to present an overview of the recent advances in PDT that can potentially reposition its utility for oral cancer treatment.

    Purpose: To determine the feasibility and efficacy of preoperative concurrent chemoradiation therapy (CCRT) with S-1, an oral fluoropyrimidine derivative, in patients with T4 oral squamous cell carcinoma (SCC). Methods and Materials: Only patients with histologically proven T4 oral SCC were included. Radiotherapy (total dose, 30 Gy) was delivered in 2-Gy daily fractions over a period of 3 weeks. Concurrently, S-1 (80 mg/m 2 /day) was administered orally twice daily for 14 consecutive days. Results: We enrolled 46 patients. All underwent radiotherapy as planned; however, oral S-1 was discontinued in 3 patients who manifested acute toxicity. Grade 3 toxicities were mucositis (20%), anorexia (9%), and neutropenia (4%). We encountered no Grade 4 adverse events or serious postoperative morbidity requiring surgical intervention. After CCRT, 32 of the 46 patients underwent radical resection; in 17 (53%) of the operated patients, the pathologic response was complete. During follow-up ranging from 7 to 58 months (median, 22 months), tumor control failed in 5 (16%) of the 32 operated patients; there were 3 local and 2 regional failures. Of the 14 non-operated patients, 8 (57%) manifested local (n = 7) or regional failure (n = 1). The 3-year overall survival rate for all 46 patients was 69%; it was significantly higher for operated than for non-operated patients (82% vs. 48%; p = 0.0288). Conclusion: Preoperative CCRT with S-1 is feasible and effective in patients with T4 oral SCC. Even in inoperable cases, CCRT with S-1 provides adequate tumor control.

    Purpose: We assessed the presence of salivary cytokines, their modulation during chemoradiation therapy (CTRT), and their association with oral mucositis severity in patients with head and neck cancer (HNC). Methods and Materials: The present prospective observational study enrolled 55 patients with locally advanced HNC requiring CTRT. We also studied 10 healthy volunteers and 10 patients with other cancers. The salivary levels of 13 cytokines were analyzed. We constructed a cytokine predictive score of oral mucositis severity. Results: The baseline salivary cytokine levels were not associated with the severity of treatment-induced oral mucositis. The cytokine levels overall increased during treatment, especially in patients with worse mucositis. In particular, on univariable analysis, an increase of interleukin (IL)-1β (area under the curve [AUC] 0.733; P=.009), IL-6 (AUC 0.746; P=.005), and tumor necrosis factor-α (AUC 0.710; P=.005) at the third week of treatment was significantly associated with the development of severe oral mucositis. On multivariable analysis, the predictive score based on the IL-1β and IL-6 changes from baseline to week 3 was an early strong predictor of higher grade oral mucositis. Conclusions: The treatment of HNC patients with concurrent CTRT induces a significant increase in the salivary levels of IL-1β, IL-6, and tumor necrosis factor-α, all positively associated with the severity of mucosal toxicity. A greater increase of IL-1β and IL-6 3 weeks after treatment initiation is predictive of worse oral mucositis, representing a potential tool for the early identification of patients at risk.

    Full Text Available Previous studies have used both systemic and topical 5-aminolevulinic acid (ALA-mediated photodynamic therapy (PDT to treat oral precancers including oral leukoplakia (OL, oral erythroleukoplakia (OEL, and oral verrucous hyperplasia (OVH as well as oral cancers including oral verrucous carcinoma (OVC and oral squamous cell carcinoma (OSCC. Systemic ALA-PDT has been used to treat oral dysplastic lesions and oral cancers with promising clinical outcomes. The efficacy of a regular topical ALA-PDT (fluence rate, 100 mW/cm2; light dose, 100 J/cm2 was tested on an extensive buccal OVC and an enhanced topical ALA-PDT (fluence rate, 200 mW/cm2; light dose, 200 J/cm2 on an early-invasive OSCC; complete regression of the carcinomas was demonstrated after 28 and 18 PDT treatments, respectively. Several previous studies showed relatively good outcomes for OL lesions treated with topical ALA-PDT. However, it was found that the regular topical ALA-PDT is very effective for OVH and OEL lesions but less so for OL lesions. Better PDT outcomes are significantly associated with OVH and OEL lesions with smaller size, pink to red color, epithelial dysplasia, or thinner surface keratin layer. Moreover, the thicker surface keratin layer on the OL lesions is responsible for the relatively poorer PDT outcomes for OL lesions. In addition, both light emitting diode light- and laser light-mediated topical ALA-PDTs are comparative treatment modalities for OVH and OEL lesions. Methotrexate- or vitamin D3-preconditioned prostate or skin carcinoma cells can accumulate more intracellular protoporphyrin IX, resulting in an increased killing of these preconditioned cells by subsequent ALA-PDT. Because chemotherapy can help destroy carcinoma cells and tumor-associated vasculatures and cryotherapy pretreatment may help the diffusion of ALA into lesional epithelial cells, the chemotherapy or cryotherapy-combined topical ALA-PDT may be a new effective PDT alternative for

    This preliminary study of 5 patients with advanced and/or recurrent cancer in the oral cavity was performed to evaluate the effectiveness of Boron Neutron Capture Therapy (BNCT). The patients received therapy with the 10 B-carrier p-boronophenylalanine (BPA) with or without borocaptate sodium (BSH) and irradiation thereafter with epithermal neutrons. All underwent 18 F-BPA PET studies before receiving BNCT to determine the accumulation ratios of BPA in tumor and normal tissues. The tumor mass was decreased in size and at minimum a transient partial response was achieved in all cases, though rapid tumor re-growth was observed in 2. Although tentative clinical responses and improvements in quality of life were recognized, obliteration of the tumor was not obtained in any of the cases. Additional studies are required to determine the utility and indication of BNCT for oral cancer. (author)

    1989-01-01

    During the period 1982-1988, 34 patients with advanced oral or oropharyngeal carcinoma were treated with radical radiation therapy combined with intraarterial chemotherapy. Five patients were clinically staged as Stage II,15 as Stage III, and 14 as Stage IV. For intraarterial chemotherapy, ACNU (25mg/body) or CDDP (20 mg/m 2 ) plus MMC (6 mg/m 2 ) was used. Overall, the complete response rate was 56%: it was independent of the site of carcinoma, clinical stage, and the kind of drugs. The two-year cumulative survival rate was 80% for Stage II, 56% for Stage III, and 61% for Stage IV. Side effects were not so severe as to continue with the withdrawal of chemotherapy. In view of the efficacy and safety, combined radiation therapy and intraarterial chemotherapy should be performed in the treatment of oral or oropharyngeal carcinoma. (N.K.)

    Salivary gland dysfunction is a common side effect of cancer therapies. Salivary secretions are reduced rapidly after starting head and neck radiotherapy. Salivary gland dysfunction has also been linked to bone marrow transplantation and to cytotoxic chemotherapy. Salivary gland stimulation during radiation has been suggested as a means of reducing radiation damage. Results of an ongoing study investigating the effects of pilocarpine on radiation-induced salivary gland dysfunction suggest that parotid function was preserved, but not submandibular/sublingual function. Also, patients receiving pilocarpine had less frequent oral complaints. Further research is necessary to develop means of preventing or alleviating the salivary side effects of cancer therapies. 37 references

    Full Text Available Oral cancer is a potentially fatal disease that constitutes an important portion of tumors that occur in the head and neck region. Oral cancer can affect overall and mental health, appearance, employment, social life, and family living. The disease can cause serious changes in the functioning of the upper aero digestive tract that affects the quality of life in patients. The use of conventional treatment modalities (surgery, radiation, and/or chemotherapy depends on tumor respectability and location as well as whether an organ preservation approach is feasible. However, their role in oral cancer treatment is nonselective and can cause damage to normal tissue. In particular, chemo radiotherapy is associated with systemic toxicities that often reduce patient compliance and prevent timely completion of therapy. The development of targeted therapies to target select pathways involved in carcinogenesis, potentially decrease systemic toxicities and morbidities associated with cancer burden and hence improve the prognosis in cancer patients. In the present article, the role of various targeted molecules in the treatment of oral cancer is discussed.

  11. D-dimer: a useful tool in gauging optimal duration of oral anticoagulant therapy?

    2013-05-01

    Full Text Available BACKGROUND AND AIM OF THE STUDY Optimal duration of oral anticoagulant therapy (OAT in idiopathic venous thromboembolism (VTE is unknown. Indefinite OAT carries an unacceptable risk of major bleeding and prospective studies have demonstrated that OAT is no longer protective after its withdrawal. How to identify the patients at risk for recurrence? D-dimer is a marker of thrombin activity. Early prospective studies showed that elevated D-dimer levels after anticoagulation had a highly predictive value for a recurrent episode. Does D-dimer assay have a role in gauging the appropriate duration of anticoagulant therapy? The PROLONG study tries to answer this question. METHOD D-dimer assay was performed one month after stopping anticoagulation. Patiens with normal D-dimer levels did not resume anticoagulation while patients with elevated D-dimer levels were randomized to discontinue or resume anticoagulation. Study end-points was the composite of recurrent VTE and major bleeding during an average follow-up of 1.4 years. RESULTS The rate of recurrence is significantly higher in patients with elevated D-dimer levels who discontinued anticoagulation. Resuming anticoagulation in this cohort of patients markedly reduces recurrent events without increasing major bleeding. DISCUSSION AND CONCLUSIONS PROLONG study is provocative, because D-dimer assay is simple, thus not requiring dedicated laboratory facilities. D-dimer test has otherwise high sensitivity but low specificity in VTE diagnosis. Aspecifically elevated D-dimer levels are available in the elderly and the majority of patients included in the study were > 65 years old, thus introducing a possible selection bias. Nonetheless the results of the study are useful for the clinician. Prolongation of vitamin K antagonists in patients with elevated D-dimer levels one month after discontinuation of OAT for a first unprovoked episode of VTE results in a favourable risk-benefit relationship. Probably this

    A promising way to acquire information about individual tumour behaviour seems to be the determination of cell kinetic properties and, even more importantly, the changes they undergo during treatment. Ideally, knowledge of changes in cell cycle at all times is desirable so that optimal regulation of the chosen chemotherapy and/or radiotherapy could lead to maximal cell death of the tumour cells with minimal toxicity for the host cells. A possible gain for increasing insight into the characteristics of a particular tumour is DNA flow cytometry. By taking multiple biopsies before and during the chemotherapy/radiotherapy treatment, it is perhaps possible to predict the expected clinical results. Research relating to this is described in this dissertation: 16 patients with non-resectable tumours of the oral cavity were treated with concurrent intra-arterial chemotherapy and radiotherapy. Multiple biopsies were analyzed with DNA flow cytometry and an attempt was made to correlate the clinical response with the acquired cellular kinetic data. The purpose of the research can be summarized as: 1. Is regional cure of non-resectable squamous cell carcinomas possible using the method described? 2. Is it possible, using DNA flow cytometry, to predict the chance of successful therapy? (Auth.)

    A large Danish study has shown that high bilirubin plasma levels and the genetic variant rs6742078 TT of the enzyme bilirubin glucuronidase UGT1A1 are associated with an increased risk of developing symptomatic gallstone disease. Recent reports regarding the significant association between bilirubin levels and symptomatic gallstone disease open a new chapter about the indication and exclusion criteria for oral dissolution therapy of symptomatic gallstone disease. A highly select subgroup of patients with small, single, radiolucent cholesterol gallstones who received oral dissolution therapy with ursodeoxycholic acid (UDCA had a reported recurrence of symptomatic gallstone disease of 50% over five years. This is probably related to the persistence of other causal risk factors for gallstones in addition to that of cholesterol suprasaturation. A subgroup of patients with high plasma bilirubin levels and the UGT1A1 genetic variant rs6742078 have a greater risk of recurrence. In conclusion, oral dissolution therapy with UDCA might still be appropriate for patients that refuse laparoscopic cholecystectomy provided they have small (< 0.5 cm, radiolucent cholesterol gallstones and a functioning gallbladder, and have mean plasma bilirubin levels below 1.33 mg/dL and are not homozygous for the UGT1A1 rs6742078 TT genotype.

    This study evaluated the effectiveness of antimicrobial photodynamic therapy (aPDT) in the treatment of oral candidiasis in a murine model using Photodithazine® (PDZ). This model of oral candidiasis was developed to allow the monitoring of the infection and the establishment of the aPDT treatment. Six-week-old female mice were immunosuppressed and inoculated with C. albicans to induce oral candidiasis. PDZ-mediated aPDT and nystatin treatment were carried out for 5 consecutive days with one application per day. The macroscopic evaluation of oral lesions was performed. After each treatment, the tongue was swabbed to recover C. albicans cells. Viable colonies were quantified and the number of CFU/ml determined. The animals were sacrificed 24 hours and 7 days after treatment and the tongues were surgically removed for histological analysis and analysis of inflammatory cytokines expression (IL-1, TNF-α and IL-6) by RT-qPCR. Data were analyzed by two-way ANOVA. PDZ-mediated aPDT was as effective as Nystatin (NYS group) in the inactivation of C. albicans, reducing 3 and 3.2 logs10 respectively, 24 h after treatment (poral lesions, while animals treated with NYS presented partial remission of oral lesions in both periods assessed. Histological evaluation revealed mild inflammatory infiltrate in the groups treated with aPDT and NYS in both periods assessed. The aPDT induced the TNF-α expression when compared with the control (P-L-) (poral candidiasis.

    The purpose of this study was to evaluate the effect of high-dose superselective intra-arterial cisplatin and concomitant radiation therapy for carcinoma of the oral cavities. The subjects consisted of 18 patients with carcinoma of the oral, and cavity treated with superselective intra-arterial infusion of high dose cisplatin (100 mg/body) concomitant with delivery of external beam radiotherapy (median total dose, 60.8 Gy) between 2001 and 2004. Sodium thiosulfate was administered intravenously to provide effective cisplatin neutlization. They were International Union Against Cancer (UICC)1997 stage II-IV (stage II: 4 patients, stage III: 4 patients, stage IV: 10 patients). Patients ranged from 43-81 years of age, with a median of 60 years, and included 14 men and 4 women. A follow-up period was 6 months minimum from the atart of the radiation therapy, the median follow up period at 28 months. The three-year overall survival rate was 71%. The three-year disease free rate and local control rate were 60% and 65%, respectively. Three-year local control rate of the T2-3 was achieved at 83%, and that for T4 at 50%. There was borderline significant difference in local control rate between T2-3 and T4 (p=0.05). We conclude that the high-dose superselective intra-arterial cisplatin and concomitant radiation therapy provides effective results in organ preservation for cancer of oral cavities. Further studies are also required to determine the validity of this method. (author)

    We aimed to analyse the effect of the introduction of fingolimod, the first oral disease-modifying therapy, on treatment utilisation and persistence in an international cohort of patients with multiple sclerosis (MS). MSBASIS, a prospective, observational sub-study of the MSBase registry, collects demographic, clinical and paraclinical data on patients followed from MS onset (n=4718). We conducted a multivariable conditional risk set survival analysis to identify predictors of treatment discontinuation, and to assess if the introduction of fingolimod has altered treatment persistence. A total of 2640 patients commenced immunomodulatory therapy. Following the introduction of fingolimod, patients were more likely to discontinue all other treatments (hazard ratio 1.64, ptreatment compared with other therapies (ptreatment discontinuation. Following the availability of fingolimod, patients were more likely to discontinue injectable treatments. Those who switched to fingolimod were more likely to do so for convenience. Persistence was improved on fingolimod compared to other medications. © The Author(s), 2015.

    This study aimed at investigating the factors affecting medication adherence in patients who use oral iron therapy due to iron deficiency anemia. A total of 96 female patients in fertile age with mean age of 30±10.1 years (range 18-53) who were admitted to Family Medicine Clinic between 01 January and 31 March 2015 and who had received iron therapy within the recent three years were enrolled in the study. Data were collected through a questionnaire form. Of the patients, 39 (40,6%) were detected not to use the medication regularly or during the recommended period. A statistically significant relationship was found between non-adherence to therapy and gastrointestinal side effects and weight gain (p<0.05). Medication adherence is deficient in patients with iron deficiency anemia. The most important reason for this seems gastrointestinal side effects, in addition to weight gain under treatment.

  2. Subtrochanteric stress fractures in patients on oral bisphosphonate therapy: an emerging problem.

    2012-01-31

    The emergence of a new variant of subtrochanteric stress fractures of the femur, affecting patients on oral bisphosphonate therapy, has only recently been described. This fracture is often preceded by pain and distinctive radiographic changes (lateral cortical thickening), and associated with a characteristic fracture pattern (transverse fracture line and medial cortical spike). A retrospective review (2007-2009) was carried out for patients who were taking oral bisphosphonates and who sustained a subtrochanteric fracture after a low velocity injury. Eleven fractures were found in 10 patients matching the inclusion criteria outlined. All were females, and taking bisphosphonates for a mean of 43 years. Five of the 10 patients mentioned prodromal symptoms, for an average of 9.4 months before the fracture. Although all fractures were deemed low velocity, 5 of 11 were even atraumatic. Two patients had previously sustained contralateral subtrochanteric fractures. Plain radiographs of two patients showed lateral cortical thickening on the contralateral unfractured femur; the bisphosphonate therapy was stopped and close surveillance was started. Patients taking oral bisphosphonates may be at risk of a new variant of stress fracture of the proximal femur. Awareness of the symptoms is the key to ensure that appropriate investigations are undertaken.

  3. Accreditation of emerging oral health professions: options for dental therapy education programs.

    The study explored the options for accreditation of educational programs to prepare a new oral health provider, the dental therapist. A literature review and interviews of 10 content experts were conducted. The content experts represented a wide array of interests, including individuals associated with the various dental stakeholder organizations in education, accreditation, practice, and licensure, as well as representatives of non-dental accrediting organizations whose experience could inform the study. Development of an educational accreditation program for an emerging profession requires collaboration among key stakeholders representing education, practice, licensure, and other interests. Options for accreditation of dental therapy education programs include establishment of a new independent accrediting agency; seeking recognition as a committee within the Commission on Accreditation of Allied Health Education Programs; or working with the Commission on Dental Accreditation (CODA) to create a new accreditation program within CODA. These options are not mutually exclusive, and more than one accreditation program could potentially exist. An educational accreditation program is built upon a well-defined field, where there is a demonstrated need for the occupation and for accreditation of educational programs that prepare individuals to enter that occupation. The fundamental value of accreditation is as one player in the overall scheme of improving the quality of higher education delivered to students and, ultimately, the delivery of health services. Leaders concerned with the oral health workforce will need to consider future directions and the potential roles of new oral health providers as they determine appropriate directions for educational accreditation for dental therapy.

  4. Iron Deficiency Anaemia in Pregnancy and Postpartum: Pathophysiology and Effect of Oral versus Intravenous Iron Therapy

    Full Text Available Nutritional iron-deficiency anaemia (IDA is the most common disorder in the world, affecting more than two billion people. The World Health Organization’s global database on anaemia has estimated a prevalence of 14% based on a regression-based analysis. Recent data show that the prevalence of IDA in pregnant women in industrialized countries is 17.4% while the incidence of IDA in developing countries increases significantly up to 56%. Although oral iron supplementation is widely used for the treatment of IDA, not all patients respond adequately to oral iron therapy. This is due to several factors including the side effects of oral iron which lead to poor compliance and lack of efficacy. The side effects, predominantly gastrointestinal discomfort, occur in a large cohort of patients taking oral iron preparations. Previously, the use of intravenous iron had been associated with undesirable and sometimes serious side effects and therefore was underutilised. However, in recent years, new type II and III iron complexes have been developed, which offer better compliance and toleration as well as high efficacy with a good safety profile. In summary, intravenous iron can be used safely for a rapid repletion of iron stores and correction of anaemia during and after pregnancy.

    Purpose: The optimal management of oral cavity squamous cell carcinoma (OCSCC) typically involves surgical resection followed by adjuvant radiotherapy or chemoradiotherapy (CRT) in the setting of adverse pathologic features. Intensity-modulated radiation therapy (IMRT) is frequently used to treat oral cavity cancers, but published IMRT outcomes specific to this disease site are sparse. We report the Dana-Farber Cancer Institute experience with IMRT-based treatment for OCSCC. Methods and Materials: Retrospective study of all patients treated at Dana-Farber Cancer Institute for OCSCC with adjuvant or definitive IMRT between August 2004 and December 2009. The American Joint Committee on Cancer disease stage criteria distribution of this cohort included 5 patients (12%) with stage I; 10 patients (24%) with stage II (n = 10, 24%),; 14 patients (33%) with stage III (n = 14, 33%),; and 13 patients (31%) with stage IV. The primary endpoint was overall survival (OS); secondary endpoints were locoregional control (LRC) and acute and chronic toxicity. Results: Forty-two patients with OCSCC were included, 30 of whom were initially treated with surgical resection. Twenty-three (77%) of 30 surgical patients treated with adjuvant IMRT also received concurrent chemotherapy, and 9 of 12 (75%) patients treated definitively without surgery were treated with CRT or induction chemotherapy and CRT. With a median follow-up of 2.1 years (interquartile range, 1.1-3.1 years) for all patients, the 2-year actuarial rates of OS and LRC following adjuvant IMRT were 85% and 91%, respectively, and the comparable results for definitive IMRT were 63% and 64% for OS and LRC, respectively. Only 1 patient developed symptomatic osteoradionecrosis, and among patients without evidence of disease, 35% experienced grade 2 to 3 late dysphagia, with only 1 patient who was continuously gastrostomy-dependent. Conclusions: In this single-institution series, postoperative IMRT was associated with promising LRC

    Clinical studies and cancer cell models emphasize the importance of targeting therapies for oral cancer. The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is highly expressed in cancer, and is a selective killing ligand for oral cancer. Signaling proteins in the wingless-type mouse mammary tumor virus (MMTV) integration site family (Wnt), Sonic hedgehog (SHH), and transforming growth factor β (TGFβ) pathways may regulate cell proliferation, migration, and apoptosis. Accordingly, the genes encoding these signaling proteins are potential targets for oral cancer therapy. In this review, we focus on recent advances in targeting therapies for oral cancer and discuss the gene targets within TRAIL, Wnt, SHH, and TGFβ signaling for oral cancer therapies. Oncogenic microRNAs (miRNAs) and tumor suppressor miRNAs targeting the genes encoding these signaling proteins are summarized, and the interactions between Wnt, SHH, TGFβ, and miRNAs are interpreted. With suitable combination treatments, synergistic effects are expected to improve targeting therapies for oral cancer.

    From January 1980 through April 1990, a total of 317 patients with an oral cancer were treated with radiation therapy at Department of Radiology, Osaka University Hospital. Twenty-seven (8.5%) of these 317 patients had other primary cancers. For statistical purposes, the expected number of other primary cancers was estimated by multiplying the age-sex specific incidence rates among Osaka residents with the Person-year at risk figures, based on the Osaka Prefectural Cancer Registry. The observed/expected [0/E] ratios were 16.00 (p<0.01) for the esophagus and 28.42 (p<0.01) for the oropharynx. The present study suggested the necessity of following up oral cancer patients, especially those who have had carcinoma of the mouth floor, in order to enable the early diagnosis of upper digestive tract cancer.

    Combination therapy with S-1, superselective intra-arterial infusion of carboplatin (CBDCA) and radiation therapy has been used to treat patients with oral cancer since 2005. In this study, the histopathological effects and toxicities following concurrent chemoradiotherapy were examined. The subjects consisted of 15 patients (10 men and 5 women) who were treated with S-1 (60-80 mg/day, 4 weeks), superselective intra-arterial infusion of CBDCA (300 mg/body) and radiation therapy (total dose 30-36 Gy) in our department from 2005 to 2009. Nine patients, showed T2 disease, 3 showed T3 disease, and another 3 showed T4 diseases. The primary cancer sites were the tongue (6 cases), buccal mucosa (4 cases), mandible gingival (3 cases), maxillary gingival (1 case), and the floor of the mouth (1 case). The histopathological effects were evaluated according to Oboshi-Shimosato classification. Grade IV was shown in 10 cases (66.7%), grade III in 1 case (6.7%), II bin 3 cases (20.0%), and II a in 1 case (6.7%). All patients completed the treatment. The pathological response of the resected tumor was grade IIb or higher in 14 cases (93.3%). While good histological effects were noted, there was one patient for whom viable tumor cells remained in the central part of the tumor. The present study indicates that further investigation is needed to determine the best dosing and dosing schedule. (author)

    Oral squamous cell carcinoma is the most common neoplasm of the oral cavity. The incidence rate accounts for 80% of total oral cancer and shows an upward trend in recent years. It has a high degree of malignancy and is difficult to detect in terms of differential diagnosis, as a consequence of which the timing of treatment is always delayed. In this work, Raman spectroscopy was adopted to differentially diagnose oral squamous cell carcinoma and oral gland carcinoma. In total, 852 entries of raw spectral data which consisted of 631 items from 36 oral squamous cell carcinoma patients, 87 items from four oral gland carcinoma patients and 134 items from five normal people were collected by utilizing an optical method on oral tissues. The probability distribution of the datasets corresponding to the spectral peaks of the oral squamous cell carcinoma tissue was analyzed and the experimental result showed that the data obeyed a normal distribution. Moreover, the distribution characteristic of the noise was also in compliance with a Gaussian distribution. A Gaussian process (GP) classification method was utilized to distinguish the normal people and the oral gland carcinoma patients from the oral squamous cell carcinoma patients. The experimental results showed that all the normal people could be recognized. 83.33% of the oral squamous cell carcinoma patients could be correctly diagnosed and the remaining ones would be diagnosed as having oral gland carcinoma. For the classification process of oral gland carcinoma and oral squamous cell carcinoma, the correct ratio was 66.67% and the erroneously diagnosed percentage was 33.33%.

    Oral squamous cell carcinoma is the most common neoplasm of the oral cavity. The incidence rate accounts for 80% of total oral cancer and shows an upward trend in recent years. It has a high degree of malignancy and is difficult to detect in terms of differential diagnosis, as a consequence of which the timing of treatment is always delayed. In this work, Raman spectroscopy was adopted to differentially diagnose oral squamous cell carcinoma and oral gland carcinoma. In total, 852 entries of raw spectral data which consisted of 631 items from 36 oral squamous cell carcinoma patients, 87 items from four oral gland carcinoma patients and 134 items from five normal people were collected by utilizing an optical method on oral tissues. The probability distribution of the datasets corresponding to the spectral peaks of the oral squamous cell carcinoma tissue was analyzed and the experimental result showed that the data obeyed a normal distribution. Moreover, the distribution characteristic of the noise was also in compliance with a Gaussian distribution. A Gaussian process (GP) classification method was utilized to distinguish the normal people and the oral gland carcinoma patients from the oral squamous cell carcinoma patients. The experimental results showed that all the normal people could be recognized. 83.33% of the oral squamous cell carcinoma patients could be correctly diagnosed and the remaining ones would be diagnosed as having oral gland carcinoma. For the classification process of oral gland carcinoma and oral squamous cell carcinoma, the correct ratio was 66.67% and the erroneously diagnosed percentage was 33.33%. The total sensitivity was 80% and the specificity was 100% with the Matthews correlation coefficient (MCC) set to 0.447 213 595. Considering the numerical results above, the application prospects and clinical value of this technique are significantly impressive.

    Purpose: Oral mucositis is a major complication of concurrent chemoradiotherapy (CRT) in head-and-neck cancer patients. Low-level laser (LLL) therapy is a promising preventive therapy. We aimed to evaluate the efficacy of LLL therapy to decrease severe oral mucositis and its effect on RT interruptions. Methods and Materials: In the present randomized, double-blind, Phase III study, patients received either gallium-aluminum-arsenide LLL therapy 2.5 J/cm 2 or placebo laser, before each radiation fraction. Eligible patients had to have been diagnosed with squamous cell carcinoma or undifferentiated carcinoma of the oral cavity, pharynx, larynx, or metastases to the neck with an unknown primary site. They were treated with adjuvant or definitive CRT, consisting of conventional RT 60–70 Gy (range, 1.8–2.0 Gy/d, 5 times/wk) and concurrent cisplatin. The primary endpoints were the oral mucositis severity in Weeks 2, 4, and 6 and the number of RT interruptions because of mucositis. The secondary endpoints included patient-reported pain scores. To detect a decrease in the incidence of Grade 3 or 4 oral mucositis from 80% to 50%, we planned to enroll 74 patients. Results: A total of 75 patients were included, and 37 patients received preventive LLL therapy. The mean delivered radiation dose was greater in the patients treated with LLL (69.4 vs. 67.9 Gy, p = .03). During CRT, the number of patients diagnosed with Grade 3 or 4 oral mucositis treated with LLL vs. placebo was 4 vs. 5 (Week 2, p = 1.0), 4 vs. 12 (Week 4, p = .08), and 8 vs. 9 (Week 6, p = 1.0), respectively. More of the patients treated with placebo had RT interruptions because of mucositis (6 vs. 0, p = .02). No difference was detected between the treatment arms in the incidence of severe pain. Conclusions: LLL therapy was not effective in reducing severe oral mucositis, although a marginal benefit could not be excluded. It reduced RT interruptions in these head-and-neck cancer patients, which might

    Therapy-related myelodysplastic syndrome (t-MDS) and therapy-related leukemia (TRL) are reported increasingly often, and we report two cases of T-MDS after concurrent chemoradiotherapy (CCRT) with oral cancer. Patients underwent CCRT with cisplatin (CDDP) or carboplatin (CBDCA). The interval between primary CCRT and t-MDS was 11 months in 1 case and 14 years in the other. Chromosomal analysis indicated abnormal karyotypes. Platinum has a relatively lower t-MDS risk than alkylating agents or topoisomerase II inhibitors, but our experience supports concurrent use of radiotherapy with platinum affects the risk of t-MDS. If pancytopenia is detected after CCRT, bone marrow and cytogenetic examinations should be conducted to rule out t-MDS. (author)

    Very little is known about the natural history of oral HPV infection. Several different methods exist to collect oral specimens and detect HPV, but their respective performance characteristics are unknown. We compared two different methods for oral specimen collection (oral saline rinse and commercial saliva kit) from 96 individuals and then analyzed the samples for HPV by two different PCR detection methods (single GP5+/6+ PCR and nested MY09/11 and GP5+/6+ PCR). For the oral rinse samples, the oral HPV prevalence was 10.4% (GP+ PCR; 10% repeatability) vs 11.5% (nested PCR method; 100% repeatability). For the commercial saliva kit samples, the prevalences were 3.1% vs 16.7% with the GP+ PCR vs the nested PCR method (repeatability 100% for both detection methods). Overall the agreement was fair or poor between samples and methods (kappa 0.06-0.36). Standardizing methods of oral sample collection and HPV detection would ensure comparability between future oral HPV studies. Copyright © 2017 Elsevier Inc. All rights reserved.

    A preliminary report of a technique of pre-surgical treatment in cleft lip and palate patients is outlined utilizing an adjustable intra-oral appliance with extra-oral strapping. The appliance is constructed with an adjustable spring for expansion and two shelves overlapping in the midline to allow palatal continuity during treatment. Frequently, only one appliance for each patient is required. The techniques of appliance construction, pre-surgical management and surgical repair of the lip are outlined.

  5. The practical management of bleedings during treatment with direct oral anticoagulants: the emergency reversal therapy

    Full Text Available Bleeding represents the most feared complication of the new oral anticoagulants, direct oral anticoagulants (DOACs, as well as all the antithrombotic therapies. During the acute phase of bleeding in patients taking anticoagulants, restoration of an effective hemostasis represents the cornerstone of practical management. While vitamin K antagonists are effectively and promptly reversed by specific antidotes such as prothrombin complex concentrates (PCCs, fresh frozen plasma or vitamin K, it is still not clear how to manage the urgent reversal of DOACs during life-threatening or major bleedings due to the lack of specific antidotes. However, in vitro and ex vivo studies have suggested some potential strategies to reverse DOACs in clinical practice, other than general support measures that are always recommended. Activated charcoal could be used in subjects with DOAC-related bleedings presenting to the emergency department within two hours of the last oral intake. Non-activated or activated PCCs (FEIBA and recombinant activated Factor VII (raFVII seem to be the optimal strategy for urgent reversal of dabigatran, while non-activated PCCs seem to have efficacy in reversing rivaroxaban. Due to its low plasma protein binding, dabigatran could be also dialyzed in urgent cases. Clinically relevant non-major bleedings and minor bleedings should be treated with general and local measures, respectively, and, when necessary, with dose delay or drug withdrawal. In this article, the Authors describe the practical approach to bleedings occurring during DOACs treatment.

    The purpose of this study was to evaluate the clinical influence of the administration of cepharanthine with or without Z-100 on the number of leukocytes during external beam radiation therapy (EBRT) in patients with oral cancer. Data from 43 patients with oral cancer who received EBRT were evaluated retrospectively. During EBRT, 14 patients received neither cepharanthine nor Z-100 (group A), 19 patients were administered 6 mg/day peroral cepharanthine (group B), and 10 patients were administered both 6 mg/day peroral cepharanthine and Z-100 injections (group C). Blood tests were performed for all patients before, during, and after EBRT. The maintenance rates of white blood cells, lymphocytes, and neutrophils were evaluated. The average maintenance rates of white blood cells in group A were 84.7% during the first half of EBRT, 81.5% during the second half of EBRT, and 88.2% at 1 month after EBRT. The corresponding rates were 112.6, 98.7, and 101.0% in group B, and 97.1, 101.5, and 90.8% in group C, respectively. The average maintenance rate of white blood cells in group B was significantly higher than that in group A during the first half of EBRT (P<0.05). Administration of cepharanthine may be useful for preventing leukopenia in patients with oral cancer treated by EBRT. (author)

    Secondary and multiple primary cancers relating radiation therapy for squamous cell carcinoma (s.c.c.) of the oral region including lip, oral cavity and oropharynx were analyzed. Out of 1,197 patients with s.c.c. treated with radiation during about 30 years from 1955 to 1983 June, 56 patients (4.7 %) were regarded as double or multiple cancer. The multiple cancer (s.c.c.) was observed frequently in the multicentric zone such as hypopharynx, esophagus and bronchus as well as in other sites of the oral cavity; 67.7 % (42 out of 62 sites). Frequency of synchronous double cancers was increased in recent ten years; 47.1 % (16/34). Careful examination to the above mentioned multicentric zone leads to early detection of secondary cancer and could be expected cure of the disease. Although possibility of radiation-induced cancer could not be ruled out as for 17 patients with late recurrence (more than 8 years), different histologic diagnosis from s.c.c. was obtained in only one (malignant fibrous histiocytoma). Therefore, it was difficult to discriminate radiation-induced cancer from late recurrence in the present study. (author)

    Type 2 diabetes is characterized by decreases in insulin secretion and insulin sensitivity. Several classes of oral antidiabetic medications are currently approved for the treatment of type 2 diabetes. A stepwise treatment approach from monotherapy to combination therapy is traditionally used; however, the frequency of treatment failure with monotherapy has resulted in a move towards earlier treatment with combination therapies that target the two principal defects in glycaemic control. One such combination regimen is repaglinide (a prandial glucose regulator that increases insulin release) plus metformin (an insulin sensitizer that inhibits hepatic glucose output, increases peripheral glucose uptake and utilization and minimizes weight gain). Findings from several clinical trials have shown that combination therapy with repaglinide plus metformin is well tolerated and results in greater reductions of haemoglobin A(1c) and fasting plasma glucose values compared with either monotherapy. Repaglinide may also provide a more suitable alternative to combination therapy with sulphonylureas and metformin because of its reduced propensity for hypoglycaemia. The combination regimen of repaglinide plus metformin should therefore be considered as a valuable option in the management of patients with type 2 diabetes when monotherapy is no longer adequate.

    Periodontal diseases are caused by infection of tissues supporting the teeth due to complex aggregate of bacteria known as biofilm and firstly colonized by streptococci. The aim of this in vitro study was to evaluate the effect of Radachlorin® and Toluidine Blue O (TBO)-mediated photodynamic therapy (PDT) on the viability of two oral streptococci. Bacterial suspensions of Streptococcus mutans and Streptococcus sanguis were subjected to either TBO or Radachlorin®, Then exposed to two different diode laser light at energy densities of 3, 6 J/cm2 at 633 nm and 6, 12 J/cm2 at 662 nm, respectively. The control groups were subjected to laser light alone, photosensitizer alone or received neither photosensitizer nor light exposure. The suspensions were then spread over specific agar mediums and viable microorganisms were counted after overnight incubation aerobically at 37°C, 5% CO2 and then reported as colony forming unit. The results indicated that photosensitization by the energy density of 6 J/cm2 with Radachlorin® and both 3 and 6 J/cm2 with TBO caused significant reduction in bacterial colony formation ( p < 0.05). Radachlorin® and TBO-mediated photodynamic therapy seem to show excellent potential in significantly killing of two oral streptococci in vitro.

    This systematic review investigated, critically appraised, and rated the evidence on agents used to prevent oral mucositis in children. A comprehensive search of the relevant literature was performed up to December 2011. Articles were included according to the inclusion/exclusion criteria and were critically appraised for validation and quality assessment using a checklist consisting of 18 categories. Each article was then rated for its strength of evidence. 16,471 articles were retrieved from 19 different databases and then reduced to 27 articles that fit the inclusion criteria. Five articles on oral care protocols supported their use to prevent oral mucositis in children. Seven articles on chlorhexidine mouthwash and three on laser therapy had conflicting evidence of its use. The preventative agents that were supported by one or two articles included: benzydamine mouthwash, iseganan mouthwash, granulocyte-macrophage colony-stimulating factor (GM-CSF) mouthwash, oral/enteral glutamine, oral propantheline and cryotherapy, oral cryotherapy, oral sucralfate suspension, prostaglandin E2 tablets, and chewing gum. The reduction in the rates of occurrence of oral mucositis when using agents of fair (B) to good (A) evidence ranged from 22% to 52%. In conclusion, this review suggests the use of oral care protocols to prevent oral mucositis in children because of their strength of evidence (fair to good). The authors suggest avoiding agents with fair to good evidence against their use (oral sucralfate suspension, prostaglandin E2 tablets, and GM-CSF mouthwash). Agents with conflicting evidence (chlorhexidine mouthwash (used solely), laser therapy, and glutamine) should also be avoided until further research confirms their efficacy. Crown Copyright © 2012.

    According to current guidelines, the first line of treatment for mild-to-moderate dehydration is oral rehydration; the second line is rehydration through a nasogastric tube. Both methods are widely underused. This study was conducted to evaluate parents' attitudes towards rehydration methods used in pediatric emergency departments. 100 questionnaires were distributed to parents of children who visited emergency room due to gastroenteritis and suspected dehydration. 75 of the parents expected their child to get IV fluids. 49 of them would refuse to consider oral rehydration. 75 of the parents would refuse to consider insertion of nasogastric tube. Parents whose children were previously treated intravenously tended to be less likely to agree to oral treatment. Parents were more prone to decline oral rehydration if the main measurement of dehydration was the child's clinical appearance, clinical appearance with vomiting, or child's refusal to drink and were more likely to agree if the main measurement was diarrhea, diarrhea with clinical appearance, or clinical personnel opinion. This is the first study to examine parents' expectations. We found that in the majority of cases, parents' expectations contradict current guidelines. Efforts should be taken to educate parents in order to allow full implementation of the guidelines.

    This two studies aim to examine application of a diode-laser in periodontal therapy. The aim of the pilot-study was to examine the immediate effect of the diode-laser in reducing the bacterial concentration in periodontal pockets. 50 patients were randomly subdivided into two groups (laser group, control group) and microbiologic samples were collected. One week after the therapy (1 st group: scaling and laser, 2 nd group: scaling) there were taken further more samples from the same periodontal pockets treated before. The microbiologic samples were evaluated to verify bacterial elimination from the periodontal pockets, especially Actinobacillus actinomycetemcomitans could be considerably eliminated from periodontal pockets by the diode laser. In the long-term study, there were two groups, one laser-group and one control-group. All 50 patients were required to have periodontal pockets with a minimum depth of 4 mm in each quadrate. The bacterial reduction, the change of bleeding on probing and the pocket depth had been evaluated six months after therapy. The irradiation with the diode laser allows considerable bacterial elimination, the index of bleeding on probing came out to be significantly better than in the control group. The reduction of pocket depth was also greater than in the control group. (author)

Postoperative parathyroid hormone (PTH) measurement is one of the methods to detect or prevent postoperative hypocalcemia. Prophylactic oral calcium supplementation is another method to prevent early postoperative hypocalcemia. The aim of this study is to detect the accurate timing of PTH and evaluate efficacy of routine oral calcium supplementation for postoperative hypocalcemia. A total of 106 patients were performed total thyroidectomy. Rotuine oral calcium supplementation was given to group 1 and no treatment to group 2 according to randomization. Serum calcium and PTH level of patients in group 2 at postoperative 6, 12 and 24 h and patients in both groups at postoperative day 7 were evaluated. Patients were compared according to age, sex, operation findings, serum calcium and PTH levels and symptomatic hypocalcemia. Half of the patients (50%) were in group 1. Most of the patients were female (83%). The most common etiology of thyroid disease was multinodular goiter (64.1%). Oral calcium supplementation was given to 18 (33.9%) patients in group 2. Symptomatic hypocalcemia for group 1 and 2 was found to be 1.9 and 33.9% respectively (p hypocalcemia. Prophylactic oral calcium supplementation therapy can prevent early post-thyroidectomy hypocalcemia with advantages of being cost effective and safe. Copyright © 2016 IJS Publishing Group Ltd.

    Background Antibiotic resistance is rising in important bacterial pathogens. Phage therapy (PT), the use of bacterial viruses infecting the pathogen in a species-specific way, is a potential alternative. Method T4-like coliphages or a commercial Russian coliphage product or placebo was orally given over 4 days to Bangladeshi children hospitalized with acute bacterial diarrhea. Safety of oral phage was assessed clinically and by functional tests; coliphage and Escherichia coli titers and enteropathogens were determined in stool and quantitative diarrhea parameters (stool output, stool frequency) were measured. Stool microbiota was studied by 16S rRNA gene sequencing; the genomes of four fecal Streptococcus isolates were sequenced. Findings No adverse events attributable to oral phage application were observed (primary safety outcome). Fecal coliphage was increased in treated over control children, but the titers did not show substantial intestinal phage replication (secondary microbiology outcome). 60% of the children suffered from a microbiologically proven E. coli diarrhea; the most frequent diagnosis was ETEC infections. Bacterial co-pathogens were also detected. Half of the patients contained phage-susceptible E. coli colonies in the stool. E. coli represented less than 5% of fecal bacteria. Stool ETEC titers showed only a short-lived peak and were otherwise close to the replication threshold determined for T4 phage in vitro. An interim analysis after the enrollment of 120 patients showed no amelioration in quantitative diarrhea parameter by PT over standard care (tertiary clinical outcome). Stool microbiota was characterized by an overgrowth with Streptococcus belonging to the Streptococcus gallolyticus and Streptococcus salivarius species groups, their abundance correlated with quantitative diarrhea outcome, but genome sequencing did not identify virulence genes. Interpretation Oral coliphages showed a safe gut transit in children, but failed to achieve

    Nuclear medicine has traditionally contributed to molecular oncology by allowing noninvasive monitoring of tumor metabolism, growth and genetic changes, thereby providing a basis for appropriate biology-based treatment planning. However, NM techniques are now being applied as an active therapeutic tool in novel molecular approaches for cancer treatment. Such areas include research on cancer therapy with radiolabeled ligands or oligonucleotides, and utilization of synergism between NM radiotherapy and gene transfer techniques. Here we will focus on novel aspects of nuclear medicine therapy

    Full Text Available Objectives. 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 prognostic factors for and compare outcome among dogs with oral malignant melanoma following excision with or without various systemic adjuvant therapies. Retrospective case series. 151 dogs with naturally occurring oral malignant melanomas treated by excision with or without adjuvant therapies from 2001 to 2012. Case accrual was solicited from Veterinary Society of Surgical Oncology members via an email list service. Information collected from case records included signalment, tumor staging, tumor characteristics, type of surgical excision, histologic diagnosis, adjuvant therapy, and survival time. The overall median survival time was 346 days. Results of multivariate analysis indicated that tumor size, patient age, and intralesional excision (vs marginal, wide, or radical excision) were considered poor prognostic indicators. All other demographic and clinical variables were not significantly associated with survival time after adjusting for the aforementioned 3 variables. A clear survival benefit was not evident with any systemic adjuvant therapy, including vaccination against melanoma or chemotherapy; however, the number of dogs in each treatment group was small. Ninety-eight dogs received no postoperative adjuvant therapy, and there was no difference in survival time between dogs that did (335 days) and did not (352 days) receive systemic adjuvant therapy. For dogs with oral malignant melanoma, increasing tumor size and age were negative prognostic factors. Complete excision of all macroscopic tumor burden improved survival time. Long-term survival was possible following surgery alone. Although systemic adjuvant therapy was not found to improve survival time, this could have been due to type II error.

    »Mixed methods« (or »multiple methods») is a fairly new concept in music therapy research. It is inspired by recent methodological developments in social science, covering the interaction of quantitative and qualitative methods in one and the same research study. Mixed methods are not the same...... as the diversity or pluralism of methods advocated by many scholars who are critical towards the principles of evidence-based medicine. This article presents a concrete example of mixed methods in music therapy research: a psycho-social study of music therapy with female cancer survivors. Problems related...

    To assess the predictors for the initiation of a basal supported oral therapy (BOT) in type 2 diabetic patients under real-life conditions in Germany. A historical cohort study based on representative German real life data (IMS(®) Disease Analyzer) was performed. The study included patients with type 2 diabetes who started an oral antidiabetic drug (OAD) treatment between 01/1995 and 12/2011. Patients with consecutive treatment data for at least 12 months before the initiation of an OAD treatment were eligible for the analysis. The time-dependent rate of patients starting an insulin therapy with a long-acting insulin was calculated by use of the Kaplan-Meier method. Multivariate Cox regression analyses were applied to identify associated factors. The study included 194,967 patients with type 2 diabetes mellitus being on OAD therapy. 24,964 patients were switched to BOT during the observational period. The probability of switching to insulin therapy was associated with three main predictors such as (1) poor metabolic control, (2) midlife age and (3) number and type of the OAD before insulinization. The variation of the HbA1c threshold to HbA1c≥7.5 leads to comparable outcomes with significant HR. The highest probability of initiating a basal supported oral therapy (BOT) under real life conditions was found for patients with poor metabolic control, midlife age and pre-treatment with specific OADs such as SU, GLI or AGI before initiation of insulin therapy.

Methods: A prospective, randomized, double-blinded study compared the effects of an antioxidant supplement (containing anthocyanosides, astaxanthin, vitamins A, C, and E, and several herbal extracts, including Cassiae semen and Ophiopogonis japonicus with placebo on patients with DES. We assessed dry eye symptoms, visual acuity, Schirmer’s test, tear film breakup time, cornea and conjunctiva fluorescein staining, serum anti-SSA/anti-SSB antibodies, and the level of reactive oxygen species (ROS in tears. The supplementation period was 8 weeks and patients were followed up every 4 weeks for 16 weeks. A linear mixed model was used to compare the groups, while within-group differences were tested by repeated-measures analysis of variance. Results: Forty-three patients, 20 and 23 in treatment and placebo groups, respectively, completed the study. Liver and renal functions were normal. Diastolic blood pressure decreased in the treatment group. There were no significant differences in systolic blood pressure, dry eye symptoms, serum anti-SSA and anti-SSB, visual acuity, intraocular pressure, or fluorescein corneal staining between the groups. Tear film breakup time scores and Schirmer’s test without topical anesthesia significantly improved in the treatment group. Tear ROS level differed between the groups and decreased after treatment. Overall subjective impression revealed a significant improvement with treatment compared with placebo. Conclusion: Oral antioxidant supplementations may increase tear production and improve tear film stability by reducing tear ROS. The vegetable-based antioxidant supplement used in this study is safe and can be utilized as

    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.

    Despite the known benefits of a mixed methods approach in health research, little is known of its use in the field of population oral health. To map the extent of literature using a mixed methods approach to examine population oral health outcomes. For a comprehensive search of all the available literature published in the English language, databases including PubMed, Dentistry and Oral Sciences Source (DOSS), CINAHL, Web of Science and EMBASE (including Medline) were searched using a range of keywords from inception to October 2017. Only peer-reviewed, population-based studies of oral health outcomes conducted among non-institutionalised participants and using mixed methods were considered eligible for inclusion. Only nine studies met the inclusion criteria and were included in the review. The most frequent oral health outcome investigated was caries experience. However, most studies lacked a theoretical rationale or framework for using mixed methods, or supporting the use of qualitative data. Concurrent triangulation with a convergent design was the most commonly used mixed methods typology for integrating quantitative and qualitative data. The tools used to collect quantitative and qualitative data were mostly limited to surveys and interviews. With growing complexity recognised in the determinants of oral disease, future studies addressing population oral health outcomes are likely to benefit from the use of mixed methods. Explicit consideration of theoretical framework and methodology will strengthen those investigations. Copyright© 2018 Dennis Barber Ltd.

    Full Text Available Studies have shown that topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT can be used successfully for the treatment of oral verrucous hyperplasia (OVH. Studies have also demonstrated that cryotherapy could be used as a treatment modality for OVH lesions. In this case report, we tested the efficacy of topical ALA-PDT, combined with cryogun cryotherapy, for an extensive OVH lesion on the right buccal mucosa of a 65-year-old male areca quid chewer. The tumor was cleared after six treatments of combined topical ALA-PDT and cryogun cryotherapy. No recurrence of the lesion was found after a follow-up period of 18 months. We suggest that our combined treatment protocol may be effective in treating OVH lesions. The treatment course may be slightly shortened with this combined protocol and was well tolerated by the patient.

    Background Updated evidence-based guidelines for the management of atrial fibrillation (AF) necessitate patient review, particularly with respect to oral anticoagulants, to ensure maximum health gain around stroke prophylaxis. Objective To quantify the level of anticoagulation utilisation in patients with a CHA 2 DS 2 -VASc ≥1/≥2 (male/female) according to evidence-based guidelines and to assess the impact of a pharmacist-led intervention to optimise therapy. Setting Fifteen general medical practices in Liverpool, North-West England with a practice population of 99,129. Method GRASP-AF software was employed to interrogate patient electronic medical records to identify and risk stratify AF patients (using CHA 2 DS 2 -VASc). A pharmacist then reviewed the medical records of those of patients not anticoagulated and with a CHA 2 DS 2 -VASc ≥1/≥2 (male/female). Recommendations were discussed with a general practitioner (GP) and those patients in whom the need for anticoagulation was agreed were invited for a consultation with either the pharmacist or GP and therapy optimised where appropriate. The GPs were responsible for managing those patients referred for diagnosis confirmation or further specialist opinion. Main outcome measure Proportion of patients eligible/not eligible for anticoagulation; proportions in whom anticoagulants initiated, refused, antiplatelets discontinued. Results Five hundred and twenty-three patients (31% of patients identified with AF and a CHA 2 DS 2 -VASc ≥1/≥2 (male/female)) were not receiving an anticoagulant (26 subsequently died or left the practice leaving 497). Three hundred and eighty-two (77%) pharmacist recommendations to a GP were agreed without modification. Following outcomes of diagnostic investigations and specialist referrals, 202 (41%) patients were candidates for anticoagulation, 251 (51%) were not eligible for anticoagulation, 103 (21%) were anticoagulated (56 warfarin, 47 DOAC). Conclusion A pharmacist

    Nitrite is a biologic factor relevant to oral and systemic homeostasis. Through an oral bacteria reduction process, it was suggested that periodontal therapy and chlorhexidine (CHX) rinse could affect nitrite levels, leading to negative effects, such as an increase in blood pressure. This 6-month randomized clinical trial evaluated the effects of periodontal therapeutic protocols on salivary nitrite and its relation to subgingival bacteria. One hundred patients with periodontitis were allocated randomly to debridement procedures in four weekly sections (quadrant scaling [QS]) or within 24 hours (full-mouth scaling [FMS]) in conjunction with a 60-day CHX (QS + CHX and FMS + CHX), placebo (QS + placebo and FMS + placebo), or no mouthrinse (QS + none and FMS + none) use. Real-time polymerase chain reaction determined total bacterial, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Streptococcus oralis, and Actinomyces naeslundii levels. Salivary nitrite concentration was determined with Griess reagent. Data were analyzed statistically at baseline and 3 and 6 months by analysis of variance, Kruskal-Wallis, Mann-Whitney U, and Spearman correlation tests (P periodontal pockets. The relationship between nitrite and bacterial levels appears weak. Short-term scaling exhibited a greater influence on nitrite concentrations then long-term CHX use.

    Clinical trials of boron neutron capture therapy (BNCT) for intracranial tumours using boronphenylalanine-fructose undertaken at Harvard-MIT and Brookhaven National Laboratory have observed acute normal tissue reactions in the skin and oral mucosa. Because the range of the 10 B(n,a) 7 Li reaction products is very short, 10-14 μm combined, knowledge of the 10B microdistribution in tissue is critical for understanding the microdosimetry and radiobiology of BNCT. This paper reports measurements of the microdistribution of 10 B in an animal model, rat skin and tongue, using high resolution quantitative autoradiography (HRQAR), a neutron-induced track etch autoradiographic technique. The steep spatial gradient and high absolute value relative to blood of the 10 B concentration observed in some strata of the rat tongue epithelium and skin are important for properly evaluating the radiobiology and the biological effectiveness factors for normal tissue reactions such as oral mucositis, which are generally assessed using the blood boron concentration rather than the tissue boron concentration.

    Objective: The concept of self – management of oral anticoagulation has been shown to entail better quality of treatment than conventional management when assessed in selected adults. We have extended the concept of self – management to include children with congenital cardiac disease......, hypothesizing self-management of oral anticoagulation is also possible in this subset of patients. Our aim was to assess the quality of self-management. Methods: We trained 14 children aged from 2.2 to 15.6 years, with a mean age of 9.7 years, and their parents, in domiciliary analysis of the International...... observed over a mean of 547 days, with a range from 214 to 953 days. The patients were within the therapeutic targetted range of the International Normalized Ratio for a median of 65.5% of the time, with a range from 17.6 % to 90.4 %. None of the patients experienced thromboembolic or bleeding...

  13. Characteristics of Symptomatic Intracranial Hemorrhage in Patients Receiving Non-Vitamin K Antagonist Oral Anticoagulant Therapy.

    Full Text Available The first non-vitamin K antagonist oral anticoagulant (NOAC introduced to the market in Japan was dabigatran in March 2011, and three more NOACs, rivaroxaban, apixaban, and edoxaban, have since become available. Randomized controlled trials of NOACs have revealed that intracranial hemorrhage (ICH occurs less frequently with NOACs compared with warfarin. However, the absolute incidence of ICH associated with NOACs has increased with greater use of these anticoagulants, and we wanted to explore the incidence, clinical characteristics, and treatment course of patients with NOACs-associated ICH.We retrospectively analyzed the characteristics of symptomatic ICH patients receiving NOACs between March 2011 and September 2014.ICH occurred in 6 patients (5 men, 1 woman; mean ± SD age, 72.8 ± 3.2 years. Mean time to onset was 146.2 ± 111.5 days after starting NOACs. Five patients received rivaroxaban and 1 patient received apixaban. None received dabigatran or edoxaban. Notably, no hematoma expansion was observed within 24 h of onset in the absence of infusion of fresh frozen plasma, activated prothrombin complex concentrate, recombinant activated factor VIIa or hemodialysis. When NOAC therapy was initiated, mean HAS-BLED and PANWARDS scores were 1.5 ± 0.5 and 39.5 ± 7.7, respectively. Mean systolic blood pressure was 137.8 ± 15.9 mmHg within 1 month before spontaneous ICH onset.Six symptomatic ICHs occurred early in NOAC therapy but hematoma volume was small and did not expand in the absence of infusion of reversal agents or hemodialysis. The occurrence of ICH during NOAC therapy is possible even when there is acceptable mean systolic blood pressure control (137.8 ± 15.9 mmHg and HAS-BLED score ≤ 2. Even stricter blood pressure lowering and control within the acceptable range may be advisable to prevent ICH during NOAC therapy.

  14. Response of the oral mucosa to porphyrin mediated boron neutron capture therapy

    2003-01-01

    Pre-clinical studies are now in progress to develop boron neutron capture therapy (BNCT) modalities for the treatment of head and neck carcinomas. BNCT is a bimodal therapy which involves the administration of a boron-10 enriched compound, that accumulates preferentially in tumours, prior to irradiation with low energy neutrons. These neutrons are captured by boron-10 atoms to produce a highly localised radiation exposure. More recently, it has been demonstrated that various boronated porphyrins can target a variety of tumours. Of the porphyrins evaluated to date, copper tetracarboranylphenyl porphyrin (CuTCPH) is a strong candidate for potential clinical evaluation. It has extremely high specificity for a variety of tumour models. Therapeutic efficacy of CuTCPH mediated BNCT has been demonstrated in pre-clinical studies using the murine EMT-6 carcinoma model. In the present investigation the response of the oral mucosa to CuTCPH mediated boron neutron capture (BNC) irradiation was assessed using a standard rat model (ventral tongue). Single exposure irradiation was carried out on the thermal neutron beam at the Brookhaven Medical Research Reactor, at 3 days after the final injection of the boronated porphyrin. The impact of CuTCPH mediated BNC irradiation on oral mucosa at therapeutically effective exposure times, assessed using the ventral tongue model, was minimal. This was primarily due to the fact that blood boron levels (from CuTCPH) were very low at the time of irradiation. Analysis of the dose-effect data for CuTCPH gave a compound biological effectiveness (CBE) factor of 2.5. It can be concluded that, although, the CBE factor (calculated using blood boron concentrations) was relatively high, CuTCPH mediated BNC irradiation should not cause significant damage at clinically relevant radiation doses. This is because blood boron levels would be very low at the time of irradiation

    The Expanded Programme on Immunization (EPI) (changed to National Programme on Immunization (NPI) in 1996) and Oral Rehydration Therapy (ORT) were launched in Nigeria in 1979. The goal of EPI was Universal Childhood Immunization (UCI) 1990, that is, to vaccinate 80% of all children age 0-2 years by 1990, and 80% of all pregnant women were also expected to be vaccinated with Tetanus Toxoid Vaccine. The Oral Rehydration Therapy was designed to teach parents with children age 0-5 years how to prepare and use a salt-sugar solution to rehydrate children dehydrated by diarrhoea. Nigeria set up Partners-in-Health to mobilize and motivate mothers to accept the programme. In 1990 a National coverage survey was conducted to assess the level of attainment. The results show that some states were able to reach the target and some were not. It therefore became necessary to evaluate the contribution of those promotional elements adopted by Partners-in-Health to motivate mothers to accept the programme. The respondents were therefore asked to state the degree to which these elements motivated them to accept the programme. The data were collected and processed through a Likert rating scale and t-test procedure for test of significance between two sample means. The study revealed that some elements motivated mothers very strongly, others strongly, and most moderately or low, with health workers as major sources of motivation. The study also revealed that health workers alone can not sufficiently motivate mothers without the help of religious leaders, traditional leaders and mass media, etc. It was therefore recommended that health workers should be intensively used along with other promotional elements to promote the NPI/ORT programme in Nigeria.

    Little is known regarding the success, failure, or complication rates of advanced implant procedures in patients after discontinuation therapy of long-term medications for the treatment of chronic myelogenous leukemia (CML). This case report presents initial results of a case involving implant placement in the mandible and maxilla as well as reduction of palatal oral pigmentation in a patient discontinuing long-term tyrosine kinase inhibitor (TKI) therapy for CML. A 57-year-old male was referred to the Department of Periodontics, University of Washington, Seattle, Washington, for an assessment of edentulous areas (tooth sites #3 and #14) and failing tooth #19. Previous medical treatment included oral administration (>10 years) of TKI for the treatment of CML. Systemic complications arising from long-term TKI therapy were treated with discontinuation of this medication. Concurrently, after multispecialty dental and medical consultation, extraction of tooth #19 with immediate implant placement and bilateral sinus augmentation with simultaneous implant placement were successfully performed during three separate surgical appointments. Additionally, marked reduction of oral palatal pigmentation was observed during the surgical and restorative phases after TKI discontinuation. Patients with a history of long-term TKIs for CML are at risk for developing complications that result in discontinuation of therapy. Long-term benefits of therapy may allow these patients to enjoy remission with an extended and improved quality of life. Patients undergoing discontinuation therapy may seek dental care. Therefore, dental providers need to understand these systemic interactions and, with multispecialty consultation, may help effectively treat these individuals.

    We sent a questionnaire to 465 institutions provided with radiotherapy units in order to search for the radiotherapists' understanding of and concern about dento-oral care in patients with head and neck radiation therapy and subsequent occurrence of radiation side effects in the oral-maxillofacial region. An analysis of 292 responses showed that in 183 (62.7%) institutions radiotherapist had experience of dental consultation of these patients for dento-oral care to the dental facility and in 109 (37.3%) they hadn't. In dental consultation, the symptomatic care for toothache etc. were more often requested than the preventive care for radiation side effects. Of 6 items of the preventive care, periodical oral examination, oral hygiene instruction and treatment for radiation caries were less frequently requested. It is concluded that radiotherapists are not fully aware of the importance of dento-oral care including the preventive care in patients with radiation therapy in the head and neck region. (author)

    The classical management of patients on oral anticoagulant therapy included hospitalisation, cessation of the anticoagulant agent, and extraction of teeth when the prothrombine levels rise. This method was substituted in the High Risk Dental Clinic at Barzilai Medical Center in Ashkelon by use of a tissue sealant (Tisseel) which does not need hospitalisation nor cessation of the anticoagulant therapy. In comparing the last 23 sessions employing the former method to the first 23 sessions using the new method there were significant differences in the cost effectiveness for the health system, provider, insurer and patient. Despite the fact that from the health system point of view the new method is much more cost effective, there is no financial incentive for the provider (hospital) nor awareness on the part of the insurer (General Sick Fund) to embrace it and 'market' it.

    Oral lichen planus (OLP) is seen frequently in patients with hepatitis C virus (HCV) infection. The aim of this study was to evaluate the occurrence of oral candidiasis, other mucosal lesions, and xerostomia during interferon (IFN) therapy for HCV infection. Of 124 patients with HCV-infected liver diseases treated with IFN therapy in our hospital, 14 (mean age 56.00 ± 12.94 years) who attended to receive administration of IFN once a week were identified and examined for Candida infection and other oral lesions and for the measurement of salivary flow. Serological assays also were carried out. Cultures of Candida from the tongue surfaces were positive in 7 (50.0%) of the 14 patients with HCV infection at least once during IFN therapy. C. albicans was the most common species isolated. The incidence of Candida during treatment with IFN did not increase above that before treatment. Additional oral mucosal lesions were observed in 50.0% (7/14) of patients: OLP in three (21.4%), angular cheilitis in three (21.4%) and recurrent aphthous stomatitis in one (7.1%). OLP occurred in one patient before treatment with IFN, in one during treatment and in one at the end of treatment. 85.7% of the oral lesions were treated with topical steroids. We compared the characteristics of the 7 patients in whom Candida was detected at least once during IFN therapy (group 1) and the 7 patients in whom Candida was not detected during IFN therapy (group 2). The prevalence of oral mucosal lesions (P=0.0075) and incidence of external use of steroids (P=0.0308) in group 1 were significantly higher than in group 2. The average body weight of group 1 decreased significantly compared to group 2 (P=0.0088). Salivary flow decreased in all subjects throughout the course of IFN treatment and returned at 6th months after the end of treatment. In group 1, the level of albumin at the beginning of the 6th month of IFN administration was lower than in group 2 (P=0.0550). According to multivariate analysis

    Mandibular protruding oral appliances represent a potentially important therapy for obstructive sleep apnea (OSA). However, their clinical utility is limited by a less-than-ideal efficacy rate and uncertainty regarding an efficacious mandibular position, pointing to the need for a tool to assist in delivery of the therapy. The current study assesses the ability to prospectively identify therapeutic responders and determine an efficacious mandibular position. Individuals (n = 202) with OSA participated in a blinded, 2-part investigation. A system for identifying therapeutic responders was developed in part 1 (n = 149); the predictive accuracy of this system was prospectively evaluated on a new population in part 2 (n = 53). Each participant underwent a 2-night, in-home feedback-controlled mandibular positioner (FCMP) test, followed by treatment with a custom oral appliance and an outcome study with the oral appliance in place. A machine learning classification system was trained to predict therapeutic outcome on data obtained from FCMP studies on part 1 participants. The accuracy of this trained system was then evaluated on part 2 participants by examining the agreement between prospectively predicted outcome and observed outcome. A predicted efficacious mandibular position was derived from each FCMP study. Predictive accuracy was as follows: sensitivity 85%; specificity 93%; positive predictive value 97%; and negative predictive value 72%. Of participants correctly predicted to respond to therapy, the predicted mandibular protrusive position proved efficacious in 86% of cases. An unattended, in-home FCMP test prospectively identifies individuals with OSA who will respond to oral appliance therapy and provides an efficacious mandibular position. The trial that this study reports on is registered on www.clinicaltrials.gov, ID NCT03011762, study name: Feasibility and Predictive Accuracy of an In-Home Computer Controlled Mandibular Positioner in Identifying Favourable

    Full Text Available Hailey-Hailey disease (HHD is a chronic familial bullous disease characterized by recurrent blisters and erosions typically at friction-prone areas of the body accompanied by acantholysis upon histologic examination. There are a number of therapies used in the management of HHD. Its symptoms have been effectively treated with antimicrobial therapies, corticosteroids and other agents such as cyclosporine and prednisone. However, such treatments are not always effective. Therefore, there is a need for new treatments for the management of HHD. In this report, a patient with long-standing HHD responsive only to high levels of prednisone is described. After the successful tapering and cessation of oral prednisone the patient began a new combination therapy of complementary doses of oral alitretinoin, and narrowband UVB therapy, which yielded a favorable response within 2-3 weeks. After 6 weeks, a mono-therapy of daily (30 mg oral alitretinoin was sufficient to maintain successful near-complete remission of the disease.

    Objective: To explore a simple, rapid and efficient method for the diagnosis of oral candidiasis in clinical practice. Methods: Totally 124 consecutive patients with suspected oral candidiasis were enrolled from Department of Oral Medicine, Peking University School and Hospital of Stomatology, Beijing, China. Exfoliated cells of oral mucosa and saliva or concentrated oral rinse) obtained from all participants were tested by three rapid smear methods(10% KOH smear, gram-stained smear, Congo red stained smear). The diagnostic efficacy(sensitivity, specificity, Youden's index, likelihood ratio, consistency, predictive value and area under curve(AUC) of each of the above mentioned three methods was assessed by comparing the results with the gold standard(combination of clinical diagnosis, laboratory diagnosis and expert opinion). Results: Gram-stained smear of saliva(or concentrated oral rinse) demonstrated highest sensitivity(82.3%). Test of 10%KOH smear of exfoliated cells showed highest specificity(93.5%). Congo red stained smear of saliva(or concentrated oral rinse) displayed highest diagnostic efficacy(79.0% sensitivity, 80.6% specificity, 0.60 Youden's index, 4.08 positive likelihood ratio, 0.26 negative likelihood ratio, 80% consistency, 80.3% positive predictive value, 79.4% negative predictive value and 0.80 AUC). Conclusions: Test of Congo red stained smear of saliva(or concentrated oral rinse) could be used as a point-of-care tool for the rapid diagnosis of oral candidiasis in clinical practice.

Based on this understanding, the initial therapeutic strategies were directed at immune modulation and inflammation control. At present, there are five licensed first-line disease-modifying drugs and two second-line treatments in MS. Currently available MS therapies have shown significant efficacy throughout many trials, but they produce different side-effect profiles in patients. Since they are well known and safe, they require regular and frequent parenteral administration and are associated with limited long-term treatment adherence. Thus, there is an important need for the development of new therapeutic strategies. Several oral compounds are in late-stage development for treating MS. Fingolimod (FTY720; Novartis, Basel, Switzerland is an oral sphingosine-1-phosphase receptor modulator which has demonstrated superior efficacy compared with placebo and interferon β-1a in Phase III studies and has been approved in the treatment of MS. We summarily review the oral compounds in study, focusing on the recent development, approval and the clinical experience with FTY720.Keywords: multiple sclerosis, oral compounds, fingolimod, fty720, sphingosine 1, phosphate, patient satisfaction

    Full Text Available Alternative therapy of animals is described, in the meaning of alternatives to veterinary therapy traditionally accepted by veterinary faculties and schools and included in their curricula. Alternative therapy composes of different disciplines, of which homeopathy is emphasised in this presentation. Information is given on the use and interest of such therapy among veterinarians and animal owners. Homeopathy as other alternative therapies, may offer great advances, if they induce any effect. Some of the disciplines are based on a scientifically accepted documentation. Others, and homeopathy in particular, are missing such a documentation of effect. The justification of including alternative therapy in treating animals is discussed. Research in alternative therapy of animals is greatly needed, in particular to evaluate therapeutic methods which are in extensive use without any documented effect. An ongoing research project in Norway on the effect of homeopathic treatment of mastitis in cows is shortly presented.

    The therapeutic procedures frequently used in oral treatments for the pathological diseases are surgical, resulting in failures of the mucosal continuity.The possibility to obtain transplantable oral epithelia from an in vitro cell culture opens new utilization perspectives not only to where it comes from, but also as a reconstructive material for other parts of the human body, such as: urethra, epithelia corneo-limbal, cornea, ocular surface. Many researchers still use controversial methods for obtaining cells. It was therefore evaluated and compared the efficiency in both methods: enzymatic and direct explant to obtain oral keratinocytes from human oral mucosa. Fragments of intra oral epithelial tissues from healthy human subjects, undergoing dental surgeries, were donated to the research project. The keratinocytes were cultivated over a feeder-layer from a previously irradiated 3T3 Swiss albino fibroblasts. In this study it was compared the time needed in the cell obtention, the best cell amount between both methods, the life-span, the cell capacity to form an in vitro epithelia and its morphologic structure. The results in the assessment of both methods have shown the possibility to obtain keratinocytes from a small oral fragment, but at the same time we may verify the advantages and peculiar restrictions for each one of both analyzed methods.

    2016-01-01

    Full Text Available Background: The human immunodeficiency virus (HIV infection which manifests as acquired immunodeficiency syndrome (AIDS is a disease involving the defects of the T-lymphocyte arm of the immune system. Certain laboratory parameters such as the cluster of differentiation (CD4 count and clinical parameters have long been used as markers of disease progression. In industrialized countries, many studies show a highly correlation between the incidence of oral lesions and immunosuppression and hence, can be used as a marker of immunosuppression. This might not be applicable to a developing country like India. In this study, efforts have been made to supplement the present knowledge on various aspects of oral manifestations in HIV patients in the Indian subcontinent. Aims: To correlate the oral manifestations in HIV/AIDS patients to the level of circulating CD4+ T-lymphocyte count and their effect in anti-retroviral therapy (ART. Subjects and Methods: A total of 104 HIV positive patients were examined for oral lesions. The CD4 count estimated on the same day by fluorescent activated cell sort count machine was then correlated with various oral lesions. Results: Oral manifestations appeared when CD4 count decreased below 500 cells/mm3. Moreover, oral lesions found at different stages showed very strong correlation to their respective CD4 count. Furthermore, there was considerable decline in the incidence of oral manifestations in patients undergoing highly active ART. Conclusions: Oral manifestations are highly predictive markers of severe immune deterioration and disease progression in HIV patients.

    We compare aromatherapy with inhaled isopropyl alcohol versus oral ondansetron for treating nausea among emergency department (ED) patients not requiring immediate intravenous access. In a randomized, blinded, placebo-controlled trial, we enrolled a convenience sample of adults presenting to an urban tertiary care ED with chief complaints including nausea or vomiting. We randomized subjects to 1 of 3 arms: inhaled isopropyl alcohol and 4 mg oral ondansetron, inhaled isopropyl alcohol and oral placebo, and inhaled saline solution placebo and 4 mg oral ondansetron. The primary outcome was mean nausea reduction measured by a 0- to 100-mm visual analog scale from enrollment to 30 minutes postintervention. Secondary outcomes included receipt of rescue antiemetic medications and adverse events. We enrolled 122 subjects, of whom 120 (98.3%) completed the study. Of randomized subjects, 40 received inhaled isopropyl alcohol and oral ondansetron, 41 received inhaled isopropyl alcohol and oral placebo, and 41 received inhaled saline solution placebo and oral ondansetron. The mean decrease in nausea visual analog scale score in each arm was 30 mm (95% confidence interval [CI] 22 to 37 mm), 32 mm (95% CI 25 to 39 mm), and 9 mm (95% CI 5 to 14 mm), respectively. The proportions of subjects who received rescue antiemetic therapy in each arm were 27.5% (95% CI 14.6% to 43.9%), 25.0% (95% CI 12.7% to 41.2%), and 45.0% (95% CI 29.3% to 61.5%), respectively. There were no adverse events. Among ED patients with acute nausea and not requiring immediate intravenous access, aromatherapy with or without oral ondansetron provides greater nausea relief than oral ondansetron alone.

    Psychological distress might affect the international normalized ratio (INR), but effects might vary depending on oral anticoagulant (OAC) therapy. To investigate the association of psychological distress with INR and clotting factors of the extrinsic pathway in patients with and without OAC therapy. We studied 190 patients with a previous venous thromboembolism (VTE); 148 had discontinued OAC therapy and 42 had ongoing OAC therapy. To assess psychological distress, all patients completed validated questionnaires to measure symptoms of depression, anxiety, worrying, anger and hostility. INR, fibrinogen, factor (F)II:C, FV:C, FVII:C and FX:C were measured as part of outpatient thrombophilia work-up. In VTE patients without OAC therapy, the odds of a reduced INR (therapy, INR was unrelated to a negative affect; however, lower FVII:C related to anxiety and worrying as well as lower FX:C related to anger and hostility were observed in patients with OAC therapy compared with those without OAC therapy. Psychological distress was associated with a reduced INR in VTE patients without OAC therapy. The direction of the association between psychological distress and activity in some clotting factors of the extrinsic coagulation pathway might differ depending on whether VTE patients are under OAC therapy or not. © 2012 International Society on Thrombosis and Haemostasis.

    Full Text Available We studied the effect of oral sirolimus, administered to prevent and treat in-stent restenosis (ISR, on the variation of serum levels of inflammatory markers following coronary stenting with bare metal stents. The mean age of the patients was 56 ± 13 years, 65% were males and all had clinically manifested ischemia. Serum levels of high sensitivity C-reactive protein (hs-CRP concentration were determined by chemiluminescence and serum levels of all other biomarkers by ELISA. One group of patients at high risk for ISR received a loading oral dose of 15 mg sirolimus and 5 mg daily thereafter for 28 days after stenting (SIR-G. A control group (CONT-G was submitted to stenting without sirolimus therapy. The increase in hs-CRP concentration was highest at 24 h after stenting in both groups. A significant difference between SIR-G and CONT-G was observed at 4 weeks (-1.50 ± 5.0 vs -0.19 ± 0.4, P = 0.008 and lost significance 1 month after sirolimus discontinuation (-1.73 ± 4.3 vs -0.01 ± 0.7, P = 0.0975. A continuous fall in MMP-9 concentration was observed in SIR-G, with the greatest reduction at 4 weeks (-352.9 ± 455 vs +395.2 ± 377, P = 0.0004, while a positive variation was noted 4 weeks after sirolimus discontinuation (227 ± 708 vs 406.2 ± 472.1, P = 0.0958. SIR-G exhibited a higher increase in P-selectin after sirolimus discontinuation at week 8 (46.1 ± 67.9 vs 5.8 ± 23.7, P = 0.0025. These findings suggest that the anti-restenotic actions of systemic sirolimus include anti-proliferative effects and modulation of the inflammatory response with inhibition of adhesion molecule expression.

    Even that orodispersible tablets (ODTs) have been successfully used in therapy for more than 20 years, there is still no compendial method of their disintegration time evaluation other than the pharmacopoeial disintegration test conducted in 800-900 mL of distilled water. Therefore, several alternative tests more relevant to in vivo conditions were described by different researchers. The aim of this study was to compare these methods and correlate them with in vivo results. Six series of ODTs were prepared by direct compression. Their mechanical properties and disintegration times were measured with pharmacopoeial and alternative methods and compared with the in vivo results. The highest correlation with oral disintegration time was found in the case of own-construction apparatus with additional weight and the employment of the method proposed by Narazaki et al. The correlation coefficients were 0.9994 (p disintegration time determination is eligible and scientifically justified.

    We evaluated the efficacy and safety of combined oral and enema therapy using polyethylene glycol (PEG) 3350 with electrolyte solution for disimpaction in hospitalized children. We retrospectively studied 28 children having functional constipation who received inpatient treatment between 2008 and 2016. The amount of oral PEG 3350 electrolyte solution administered was 50-70 mL/kg/d (PEG 3350, 3-4.1 g/kg/d), and an enema solution was administered 1-2 times a day as a single dose of 15-25 mL/kg (PEG 3350, 0.975-1.625 g/kg/d). A colon transit time (CTT) test based on the Metcalf protocol was performed in some patients. Administration of oral and enema doses of PEG 3350 electrolyte solution showed 2.1±0.3 times and 2.9±0.4 times, respectively. After disimpaction, the frequency of defecation increased from 2.2±0.3 per week to once a day (1.1±0.1 per day). The number of patients who complained of abdominal pain was reduced from 15 (53.6%) to 4 (14.3%). Before hospitalization, nine patients underwent a CTT test, and 5 of 9 patients (55.6%) were classified as belonging to a group showing abnormalities. And in some patients, mild adverse effects were noted. We examined electrolytes and osmolality before and after disimpaction in 16 of 28 patients, and no abnormalities were noted. In terms of therapeutic efficacy and safety, combined oral and enema therapy using high-dose PEG 3350 with electrolytes is considered superior to conventional oral monotherapy or combined oral and enema therapy on an outpatient basis.

    A technique of radiation therapy treatment planning designed to allow the assignment of dosage limits directly to chosen points in the computer-displayed cross-section of the patient. These dosage limits are used as constraints in a linear programming attempt to solve for beam strengths, minimizing integral dosage. If a feasible plan exists, the optimized plan will be displayed for approval as an isodose pattern. If there is no feasible plan, the operator/therapist can designate some of the point dosage constraints as ''relaxed.'' Linear programming will then optimize for minimum deviation at the relaxed points. This process can be iterated and new points selected until an acceptable plan is realized. In this manner the plan is optimized for uniformity as well as overall low dosage. 6 claims, 6 drawing figures

    The Candida genus expresses virulence factors that, when combined with immunosuppression and other risk factors, can cause different manifestations of oral candidiasis. The treatment of mucosal infections caused by Candida and the elucidation of the disease process have proven challenging. Therefore, the study of experimentally induced oral candidiasis in rats and mice is useful to clarify the etiopathology of this condition, improve diagnosis, and search for new therapeutic options because the disease process in these animals is similar to that of human candidiasis lesions. Here, we describe and discuss new studies involving rat and mouse models of oral candidiasis with respect to methods for inducing experimental infection, methods for evaluating the development of experimental candidiasis, and new treatment strategies for oral candidiasis.

    The Candida genus expresses virulence factors that, when combined with immunosuppression and other risk factors, can cause different manifestations of oral candidiasis. The treatment of mucosal infections caused by Candida and the elucidation of the disease process have proven challenging. Therefore, the study of experimentally induced oral candidiasis in rats and mice is useful to clarify the etiopathology of this condition, improve diagnosis, and search for new therapeutic options because the disease process in these animals is similar to that of human candidiasis lesions. Here, we describe and discuss new studies involving rat and mouse models of oral candidiasis with respect to methods for inducing experimental infection, methods for evaluating the development of experimental candidiasis, and new treatment strategies for oral candidiasis.

    Retrospective studies on oral cancer patient profiles related to risk habits could provide etiologic clues for prevention in specific geographic areas. To study risk habit characteristics of oral cancer patients. A cross sectional retrospective case record study of oral cancer patients who reported during 1991-2000 to Karnataka Cancer Therapy and Research Institute, Hubli, India was conducted. Data on socio-demography, histopathology, site of cancer and risk habit profiles of the patients were recorded in a predesigned Performa by one calibrated examiner with internal validity checks. The 1,472 oral cancer patients constituted 11% of total cancer patients. Mean age of the patients was 55 years, ranging from 12-88, with a male: female ratio of 2:1. 1,110 (75%) oral cancer patients had risk habits, 55% were habituated for >10 years and 25% were habit free. 751(51%) patients had individual and 359(24%) had combined risk habits. Majority 59% were chewers of betel quid alone (17%)/betel quid with tobacco (42%); smokers were (31%) and alcohol users were (14%) of patients. Chewers of gutkha, khaini were more in 40 years. Risk habituates were highest (87%) in patients with cancer of buccal mucosa, commonly affected site attributed to chewing habit in (51%) of patients. The prevalence of oral cancer was higher among elderly males predominantly with risk habits of betel quid/tobacco chewing and smoking for more than 10 years.

    This project studied the prevalence of oral soft tissue disease in HIV-infected children treated with highly active antiretroviral therapy (HAART). Thirty-eight HIV-infected children participated in the study. Twenty-three of these patients were treated with HAART while 14 received exclusively reverse transcriptase inhibitors (RTI) and served as controls. The children were examined three times at approximately one-month intervals while their health history and laboratory data were abstracted from medical charts. Analyses were performed to determine differences in lesion prevalence between treatment groups as well as between lesion and no lesion groups with regard to immune differences. Thirty patients (79%) had oral lesions detected in at least one visit. There were no differences in specific lesion prevalence between HAART compared with RTI-treated children. However, a trend for more oral candidiasis in the latter group was observed. Subjects with oral soft tissue lesions had lower CD4 counts (P = 0.04) and percentage (P = 0.01) but similar viral loads when compared to patients without oral soft tissue disease. HAART does not appear to significantly affect oral soft tissue disease prevalence in HIV-infected children. Presence of lesions was associated with decreased immunity and may signal advancing disease.

    Purpose Assess the effectiveness of an orofacial myofunctional therapeutic program in patients with oral or oropharyngeal cancer submitted to adjuvant radiotherapy through pre- and post-program comparison of maximum mandibular opening. Methods Prospective study involving five adult patients and five elderly patients postoperatively to oral cavity/oropharynx surgery who were awaiting the beginning of radiotherapy or had undergone fewer than five treatment sessions. The study participants had their maximum jaw opening measured using a sliding caliper at the beginning and end of the program. Two mobility exercises and three mandibular traction exercises were selected and weekly monitored presentially for 10 weeks. Descriptive data and pre- and post-therapy comparative measures were statistically analyzed using the Wilcoxon test. Results Ten patients (two women and eight men) with mean age of 58.4 years, median of 57.0 years, completed the therapeutic program. They presented mean maximum mandibular opening of 31.6 ± 11.7 and 36.4 ± 8.0 mm pre- and post-therapy, respectively (p =0.021). Conclusion The proposed orofacial myofunctional therapeutic program increased the maximum jaw opening of patients referred to adjuvant radiotherapy for oral cavity or oropharynx cancer treatment.

    Full Text Available Context: In developing countries many chronic conditions including periodontitis are on the rise. Oral health attitudes and beliefs are important factors affecting oral health behavior. Aims: The aim of this pilot study was to assess the existing knowledge about periodontal disease and its impact on treatment seeking behavior in a group of population visiting the out-patient Department of Periodontics, Yenepoya Dental College, India. This study also attempted to identify deficit in the knowledge if present. Settings and Design: This is a written questionnaire based pilot study. 143 subjects (89 male and 54 female agreed to participate in the study. Simple random sampling was used for recruitment. Subjects and Methods: A written questionnaire consisting of 18 questions was given to the patients. Only one correct answer was present and the score given was + 1. The knowledge of the subjects was reflected by their ability to select a correct answer from the number of distractors (multiple choices, prespecified answers. Statistical Analysis Used: SPSS software version 15.0 is used for all statistical analysis. The Chi-square test was employed to assess the passive knowledge of the participants in relation to their age. Results: We found a deficit in the knowledge in all the topics investigated. No consistent relationship between age and gender was found. Female respondents had better knowledge about oral hygiene compared to males. Conclusion: We made an attempt to assess the knowledge of periodontitis among the participants of this study. Knowledge deficit was found in the population surveyed. This knowledge deficit could be one of the reasons why patients do not seek periodontal treatment routinely unless there are acute symptoms. There is urgent need to educate the patients about the periodontal disease, the need for the treatment of periodontitis and advanced treatment modalities available.

    Full Text Available The nonsurgical strategies for locally advanced oral cancer are desirable. Superselective intra-arterial infusion with radiotherapy was utilized for this purpose, and there are two types of superselective intra-arterial infusion methods: The Seldinger method and the retrograde superselective intra-arterial chemotherapy (HFT method. In one case, the HFT method was applied to locally advanced tongue cancer, and the Seldinger method was used for additional administration of cisplatin (CDDP to compensate for a lack of drug flow in the HFT method. In another case, the HFT method was applied to locally advanced lower gingival cancer. The Seldinger method was applied to metastatic lymph nodes. In both cases, additional administration of CDDP using the Seldinger method resulted in a complete response. The combination of the HFT and Seldinger methods was useful to eradicate locally advanced oral cancer because each method compensated for the defects of the other.

    A mixed methods research design was used to investigate the effects of a music therapy CD (MTCD) creation intervention on pediatric oncology patients' distress and coping during their first radiation therapy treatment. The music therapy method involved children creating a music CD using interactive computer-based music software, which was "remixed" by the music therapist-researcher to extend the musical material. Eleven pediatric radiation therapy outpatients aged 6 to 13 years were randomly assigned to either an experimental group, in which they could create a music CD prior to their initial treatment to listen to during radiation therapy, or to a standard care group. Quantitative and qualitative analyses generated multiple perceptions from the pediatric patients, parents, radiation therapy staff, and music therapist-researcher. Ratings of distress during initial radiation therapy treatment were low for all children. The comparison between the two groups found that 67% of the children in the standard care group used social withdrawal as a coping strategy, compared to 0% of the children in the music therapy group; this trend approached significance (p = 0.076). MTCD creation was a fun, engaging, and developmentally appropriate intervention for pediatric patients, which offered a positive experience and aided their use of effective coping strategies to meet the demands of their initial radiation therapy treatment.

    To estimate the effect of fasting during Ramadan (the ninth lunar month) on adherence to oral hormonal therapies (OHT) among breast cancer (BC) patients. During Ramadan 2010, 139 BC patients were interviewed at the Egyptian National Cancer Institute. They were asked about fasting as well as intake of OHT in Ramadan and in the preceding month. The median age was 50years and most patients were postmenopausal with good performance status and non-metastatic disease. The median number of fasting days was 18% and 93% of patients were fasting 80% or more of Ramadan. Tamoxifen and aromatase inhibitors were used in 64% and 36%, respectively. Adherence to OHT during Ramadan and its preceding month were 94.2% and 95.7%, respectively (p=0.77). In univariate analysis, non-adherence prior to Ramadan and shorter duration of OHT were predictors of non-adherence during Ramadan (PRamadan, this does not negatively impact compliance with treatment.

    1986-01-01

    In an effort to improve tumor control by radiation therapy, a treatment regimen consisting of concurrent combination of bleomycin (90 mg/3 weeks) and radiation (30 Gy/3 weeks) was applied. Between 1972 and 1981, 287 patients with squamous cell carcinoma in the oral cavity were subjected to this bleomycin-radiation combination regimen. All except 4 patients experienced marked response after treatment using the bleomycin-radiation combination alone. One hundred thirty-four patients (47 %) obtained CR and 149 (53 %) PR. Higher CR rates were obtained in patients with carcinoma of the lower gum (62 %), of the upper gum (68 %), and of the cheek mucosa (43 %), compared to patients with carcinoma of the floor of the mouth (21 %), and of the tongue (15 %). In each of the tumor sites, small lesions (T1, T2) obtained higher CR rates, compared with large lesions (T3, T4). Of the 134 patients who experienced CR, 83 were observed without any further treatment after bleomycin-radiation combination alone. Local recurrence-free rates of these patients were 72 % for T1, T2 lesions and 48 % for T3, T4 lesions. Local control rates were increased to 85 % and 78 %, respectively, with successful salvage treatment involving surgery or interstitial radiotherapy for post-irradiation failures. (author)

    2014-05-01

    Although diarrheal mortality is cheaply preventable with oral rehydration therapy (ORT), over 700,000 children die of diarrhea annually and many health providers fail to treat diarrheal cases with ORT. Provision of ORT may differ between for-profit and public providers. This study used Demographic and Health Survey data from 19,059 children across 29 countries in sub-Saharan Africa from 2003 to 2011 to measure differences in child diarrhea treatment between private for-profit and public health providers. Differences in treatment provision were estimated using probit regression models controlling for key confounders. For-profit providers were 15% points less likely to provide ORT (95% confidence interval [CI] 13-17) than public providers and 12% points more likely to provide other treatments (95% CI 10-15). These disparities in ORT provision were more pronounced for poorer children in rural areas. As private healthcare in sub-Saharan Africa continues to expand, interventions to increase private sector provision of ORT should be explored.

    We present a system for data-driven therapy decision support based on techniques from the field of recommender systems. Two methods for therapy recommendation, namely, Collaborative Recommender and Demographic-based Recommender , are proposed. Both algorithms aim to predict the individual response to different therapy options using diverse patient data and recommend the therapy which is assumed to provide the best outcome for a specific patient and time, that is, consultation. The proposed methods are evaluated using a clinical database incorporating patients suffering from the autoimmune skin disease psoriasis. The Collaborative Recommender proves to generate both better outcome predictions and recommendation quality. However, due to sparsity in the data, this approach cannot provide recommendations for the entire database. In contrast, the Demographic-based Recommender performs worse on average but covers more consultations. Consequently, both methods profit from a combination into an overall recommender system.

    Full Text Available Abstract Background The combination of gemcitabine (GEM and S-1, an oral 5-fluorouracil (5-FU derivative, has been shown to be a promising regimen for patients with unresectable pancreatic cancer. Methods Six patients with advanced pancreatic cancer were enrolled in this pharmacokinetics (PK study. These patients were treated by oral administration of S-1 30 mg/m2 twice daily for 28 consecutive days, followed by a 14-day rest period and intravenous administration of GEM 800 mg/m2 on days 1, 15 and 29 of each course. The PK parameters of GEM and/or 5-FU after GEM single-administration, S-1 single-administration, and co-administration of GEM with pre-administration of S-1 at 2-h intervals were analyzed. Results The maximum concentration (Cmax, the area under the curve from the drug administration to the infinite time (AUCinf, and the elimination half-life (T1/2 of GEM were not significantly different between GEM administration with and without S-1. The Cmax, AUCinf, T1/2, and the time required to reach Cmax (Tmax were not significantly different between S-1 administration with and without GEM. Conclusion There were no interactions between GEM and S-1 regarding plasma PK of GEM and 5-FU.

    Dosimetry studies have been carried out at thermal and epithermal columns of Lvr-15 research reactor for investigating the spatial distribution of gamma dose, fast neutron dose and thermal neutron fluence. Two different dosimetry methods, both based on solid state detectors, have been studied and applied and the accuracy and consistency of the results have been inspected. One method is based on Fricke gel dosimeters that are dilute water solutions and have good tissue equivalence for neutrons and also for all the secondary radiations produced by neutron interactions in tissue or water phantoms. Fricke gel dosimeters give the possibility of separating the various dose contributions, i.e. the gamma dose, the fast neutron dose and the dose due to charged particles generated during thermal neutron reactions by isotopes having high cross section, like 10-B. From this last dose, thermal neutron fluence can be obtained by means of the kerma factor. The second method is based on thermoluminescence dosimeters. In particular, the developed method draw advantage from the different heights of the peaks of the glow curve of such phosphors when irradiated with photons or with thermal neutrons. The results show that satisfactory results can be obtained with simple methods, in spite of the complexity of the subject. However, the more suitable dosimeters and principally their utilization and analysis modalities are different for the various neutron beams, mainly depending on the relative intensities of the three components of the neutron field, in particular are different for thermal and epithermal columns.

    Neoadjuvant therapy plays an important role for organ preservation and survival rate in the treatment of oral cancer. We clinically compared the effect of neoadjuvant radiotherapy and chemoradiotherapy in patients with oral cancer. We retrospectively examined 47 patients diagnosed with oral squamous cell carcinoma who underwent neoadjuvant therapy followed by curative surgery in the oral and maxillofacial surgery department of Ehime University Hospital. We divided them into two groups: radiotherapy alone (24 cases) and chemoradiotherapy (23 cases). The patients in the radiotherapy group underwent irradiation of 32.6{+-}5.0 Gy (mean {+-}SD). The patients in the chemoradiotherapy group received a low-dose fraction of cisplatin (8 mg/mm{sup 2}/day, 5 days a week; total dose: 139.4{+-}67.1 mg) and 5-fluorouracil (300 mg/mm{sup 2}/day, 5 days a week; total dose: 5,900{+-}1,839.8 mg) combined with simultaneous irradiation of 31.0{+-}3.2 Gy. None of the 24 patients had a complete response to radiotherapy alone and 12 (50%) had a partial response. Six (26%) of the 23 patients had a complete response to chemoradiotherapy and 12 (52%) had a partial response. The primary control rate (82.6%) to chemoradiotherapy was higher than that (67.5%) to radiotherapy alone although no significant difference was found. The 5-year survival rate was 64.3% in the radiotherapy group and 62.8% in the chemoradiotherapy group. The findings of the present study suggest that while the combination of radiation and cisplatin/5-fluorouracil in neoadjuvant therapy for oral cancer may not bring a significant benefit to improve survival rate, the primary local control rate is improved in comparison with radiotherapy alone.

    La hidratación oral es uno de los descubrimientos médicos más importantes del siglo veinte; su base fisiológica es el transporte acoplado de sodio y otros solutos, que favorece el ingreso de agua a las células del intestino. El suero de hidratación oral (SHO con la fórmula recomendada por la Organización Mundial de la Salud (OMS, utiliza como so luto transportador la glucosa. Su osmolaridad es ligeramente mayor que la de los líquidos corporales: 311 mOsm/L.

    ORT solution with the composition recommended by the World Health Organization, is one of the most important medical advances of the present century; it has, however, some drawbacks that may partly explain why it is used with a lower frequency than it is desirable. In order to overcome such limitations other substances have been tried for the preparation of OR solutions; the ideal preparation should both hydrate and prevent further dehydration, decrease the volume of stools and the duration of diarrhea and provide some nutrients. The following substances have been tried for the preparation of oral solution: glycine, glutamine, alanine, rice and other cereals, maltodextrines, protein hydrolysates and low osmolarity solutions; in light of the results obtained so far, these products offer no advantage over the standard solution.

    Oral hygiene maintenance is crucial for prevention of various oral diseases. Oral hygiene practices across the country vary largely and people in peri-urban and rural areas use traditional methods of oral hygiene like powders, bark, oil and salt etc. Their effect on oral soft and hard tissues need to be studied to understand their beneficial and/ or harmful effects on maintenance of oral hygiene and prevention or causation of oral diseases. This study aimed to assess the plaque-cleaning efficacy, gingival bleeding, recession and tooth wear with different traditional oral hygiene methods as compared to use of toothpaste-toothbrush, the most accepted method of oral hygiene practice. Hospital based cross sectional analytical study. Results: Total 1062 traditional oral hygiene method users were compared with same number of toothpaste-brush users. The maximum number in the former group used tooth powder (76%) as compared to other indigenous methods, such as use of bark of trees etc and out of tooth powder users; almost 75% reported using red toothpowder. The plaque scores and gingival bleeding & recession were found to be more in traditional oral hygiene method users. The toothwear was also more severe among the toothpowder users. Traditional methods were found to be inferior in plaque control as was documented by increased bleeding and gingival recession. Its effect on hard tissues of teeth was very damaging with higher tooth wear scores on all surfaces.

    To study the beneficial effects of oral contraceptive (OC) therapy following gonadotropin-releasing hormone agonist (GnRH-a) administration in women with polycystic ovary disease (PCOD). Twenty-three hyperandrogenic women (aged 15-39) were randomized into two groups; GnRH-a (depot every 28 days) for six months or combination therapy (GnRH-a plus OC "addback") for six months. Following six months of treatment with either therapy, all patients received OC therapy for at least six months. The hormonal state was evaluated at three-month intervals. Hormone levels of luteinizing hormone (LH), testosterone (T) and free T remained suppressed within the normal range in 11 of 17 patients (65%) during the six months of OC only therapy, while the other six patients showed "escape" from suppression, with the LH, T and free T concentrations rising to pre-GnRH-a treatment levels. Use of OC addback therapy did not potentiate the long-acting therapeutic effect of GnRH-a pretreatment; three of six patients in the escape group were pretreated with combination therapy and three with GnRH-a only. In the majority of women with PCOD, OC therapy following GnRH-a administration was effective in maintaining ovarian androgen suppression. Failure to maintain ovarian suppression in this patient population was associated with higher elevations of baseline free T concentrations.

    Chronic thromboembolic pulmonary hypertension (CTEPH) occurs when pulmonary emboli fail to resolve with anticoagulation. For patients with inoperable or residual CTEPH, riociguat is currently the only therapy approved by the United States Food and Drug Administration. However, some patients with CTEPH may require therapy beyond riociguat, such as intravenous prostacyclins, which can present significant administration challenges in patients with complex comorbid conditions. We describe a 42-year-old man with T12 paraplegia complicated by CTEPH (functional class IV with substantial right ventricular dysfunction) and severe pressure ulcers. In order to facilitate goals of care (hospital discharge to a skilled nursing facility where parenteral prostanoids could not be administered), he underwent rapid transition from intravenous treprostinil to oral selexipag in the form of a cross-taper over 6 days. The patient required readmission due to worsening symptoms and was transitioned back to intravenous treprostinil; he tolerated conversion to oral treprostinil for approximately 4 months, but it was subsequently discontinued due to nausea and modified goals of care. The patient underwent transition to hospice care 3 months later and eventually died from clinical deterioration. To our knowledge, this is the first report to describe transition from intravenous treprostinil to selexipag as well as conversion from parenteral treprostinil to oral treprostinil in a patient with CTEPH and illustrates the approaches to and potential issues with prostanoid transitions. Additional observations are necessary to better understand the relative roles of selexipag and oral treprostinil regarding comparative efficacy and tolerability. © 2017 Pharmacotherapy Publications, Inc.

    Full Text Available Aim. To evaluate treatment adherence and prevalence of CYP2C9 and VKORC1 gene mutations in patients with atrial fibrillation (AF and provide rationale of choice for oral anticoagulation therapy.Material and methods. Treatment adherence was evaluated in 137 AF patients (aged 35-85 years with quantitative estimation of drug therapy adherence along with compliance to medical support and lifestyle modifications. Among them 82 patients underwent polymerase chain reaction (PCR analysis of CYP2C9 and VKORC1 gene polymorphisms.Results. Patients receiving anticoagulation therapy are characterized by lower level of adherence compared to patients without anticoagulants (65.2±19.3% vs 68.5±19.1%; Wald-Wolfowitz; p<0.05. Considering all studied parameters men are less adherent than women (54.7±18.6% vs 60.6±16.7%; Kolmogorov-Smirnov; p<0.05. Patients receiving new oral anticoagulants (NOAC have better compliance compared with patients of warfarin group. Mutations in CYP2C9 gene were detected in 32.9%, VKORC1 – in 68.3%, and their combination – in 21.9% of study participants. Warfarin therapy may be potentially dangerous in such patients due to low adherence.Conclusion. Considering high prevalence of CYP2C9 and VKORC1 gene mutations treatment adherence should be estimated to optimize choice of anticoagulation therapy. NOAC treatment should be considered in patients with low adherence for prevention of thromboembolic complications.

    We developed a Markov microsimulation model among hypothetical cohorts of community-dwelling US white women without prior major osteoporotic fractures over a lifetime horizon. At ages 75 and 80, adding 1 year of exercise to 5 years of oral bisphosphonate therapy is cost-effective at a conventionally accepted threshold compared with bisphosphonates alone. The purpose of this study was to examine the cost-effectiveness of the combined strategy of oral bisphosphonate therapy for 5 years and falls prevention exercise for 1 year compared with either strategy in isolation. We calculated incremental cost-effectiveness ratios [ICERs] (2014 US dollars per quality-adjusted life year [QALY]), using a Markov microsimulation model among hypothetical cohorts of community-dwelling US white women with different starting ages (65, 70, 75, and 80) without prior history of hip, vertebral, or wrist fractures over a lifetime horizon from the societal perspective. At ages 65, 70, 75, and 80, the combined strategy had ICERs of $202,020, $118,460, $46,870, and $17,640 per QALY, respectively, compared with oral bisphosphonate therapy alone. The combined strategy provided better health at lower cost than falls prevention exercise alone at ages 70, 75, and 80. In deterministic sensitivity analyses, results were particularly sensitive to the change in the opportunity cost of participants' time spent exercising. In probabilistic sensitivity analyses, the probabilities of the combined strategy being cost-effective compared with the next best alternative increased with age, ranging from 35 % at age 65 to 48 % at age 80 at a willingness-to-pay of $100,000 per QALY. Among community-dwelling US white women ages 75 and 80, adding 1 year of exercise to 5 years of oral bisphosphonate therapy is cost-effective at a willingness-to-pay of $100,000 per QALY, compared with oral bisphosphonate therapy only. This analysis will help clinicians and policymakers make better decisions about treatment

  10. Injuries and outcomes associated with traumatic falls in the elderly population on oral anticoagulant therapy.

    Fall risk for older adults is a multi-factorial public health problem as 90% of geriatric injuries are caused by traumatic falls. The CDC estimated 33% of adults >65 years incurred a fall in 2011, with 30% resulting in moderate injury. While much has been written about overall risk to trauma patients on oral anticoagulant (OAC) therapy, less has been reported on outcomes in the elderly trauma population. We used data from the National Trauma Data Bank (NTDB) to identify the types of injury and complications incurred, length of stay, and mortality associated with OACs in elderly patients sustaining a fall. Using standard NTDB practices, data were collected on elderly patients (≥65 years) on OACs with diagnosis of fall as the primary mechanism of injury from 2007 to 2010. Univariate analysis was used to determine patient variables influencing risk of fall on OACs. Odds ratios were calculated for types of injury sustained and post-trauma complications. Logistic regression was used to determine mortality associated with type of injury incurred. Of 118,467 elderly patients sampled, OAC use was observed in 444. Predisposing risk factors for fall on OACs were >1 comorbidity (p3 complications (p<0.0001); the most significant being ARDS and ARF (p<0.0001). The mortality rate on OACs was 16%. Injuries to the GI tract, liver, spleen, and kidney (p<0.0002) were more likely to occur. However, if patients suffered a mortality, the most significant injuries were skull fractures and intracranial haemorrhage (p<0.0001). Risks of anticoagulation in elderly trauma patients are complex. While OAC use is a predictor of 30-day mortality after fall, the injuries sustained are markedly different between the elderly who die and those who do not. As a result there is a greater need for healthcare providers to identify preventable and non-preventable risks factors indicative of falls in the anti-coagulated elderly patient.

    Calf scours is a primary cause of morbidity and mortality in the dairy industry. Effective treatments are needed to minimize death, maximize welfare, and maintain growth and productivity. The objective of this trial was to compare the efficacy of a commercially available nutritional supplement (Diaque, Boehringer-Ingelheim Vetmedica Inc., St. Joseph, MO) and i.v. lactated Ringer's solution (LRS) in rehydrating, preventing acidemia, and correcting electrolyte imbalances in an experimental model for calf scours. Twenty-four colostrum-fed suckling dairy calves were used in a modified crossover design. An osmotic diarrhea was induced by orally feeding commercial milk replacer modified with high level of sucrose to create a hypertonic milk solution, and administering oral hydrochlorothiazide and spironolactone for 48 h. The intention was to create a challenge sufficient to result in moderately dehydrated, standing calves without producing severe depression or loss of suckle. The efficacy of i.v. fluid therapy and a commercial nutritional supplement were subsequently compared for reversing the effects of the diarrheal disease. Treatment A consisted of administering the nutritional supplement according to label directions (100 g in 1.9 L of warm water, 3 times a day), and treatment B consisted of i.v. LRS (2 L, once a day). Clinical signs and laboratory results were obtained once daily by a blinded observer. The induction method was effective in creating the desired effect, as demonstrated by weight loss and subjective health and hydration scores. Both treatment groups experienced increases in body weight, base excess, and bicarbonate, and decreases in total protein and packed cell volume following treatment. Both i.v. LRS and Diaque are effective methods to correct hypovolemia and control derangements in acid-base status in calves with diarrhea and dehydration. The Authors.

    2004-09-01

    Full Text Available The term mucositis is coined to describe the adverse effects of radiation and chemotherapy treatments. Mucositis is one of the most common adverse reactions encountered in radiation therapy for head and neck cancers, as well as in chemotherapy, in particular with drugs affecting DNA synthesis (Sphase-specific agents such as fluorouracil, methotrexate, and cytarabine. Mucositis may limit the patient's ability to tolerate chemotherapy or radiation therapy, and nutritional status is compromised. It may drastically affect cancer treatment as well as the patient's quality of life. The incidence and severity of mucositis will vary from patient to patient. It will also vary from treatment to treatment. It is estimated that there is 40% incidence of mucositis in patients treated with standard chemotherapy and this will not only increase with the number of treatment cycles but also with previous episodes. Similarly, patients who undergo bone marrow transplantation and who receive high doses of chemotherapy have a 76% chance of getting mucositis. Patients receiving radiation, in particular to head and neck cancers, have a 30% to 60% chance. The exact pathophysiology of development is not known, but it is thought to be divided into direct and indirect mucositis. Chemotherapy and/or radiation therapy will interfere with the normal turnover of epithelial, cells leading to mucosal injury; subsequently, it can also occur due to indirect invasion of Gram-negative bacteria and fungal species because most of the cancer drugs will cause changes in blood counts. With the advancement in cytology, a more precise mechanism has been established. With this understanding, we can select and target particular mediators responsible for the mucositis. Risk factors such as age, nutritional status, type of malignancy, and oral care during treatment will play important roles in the development of mucositis. Many treatment options are available to prevent and treat this

    , using the functional oral intake scale as parameter of safe progression for oral feeding. METHODS: We carried out a retrospective study on forty-nine patients with neurogenic dysphagia under speech therapy sessions while in the wards and a comparison between the results of the functional oral intake scale before and after the therapy sessions(measuring the amount and type of orally-taken food in a safe manner by the patients. Possible factors affecting the therapy such as etiology of the neurologic disease, age, respiratory and clinical conditions, alertness, time and duration of the therapy sessions were studied. RESULTS: over the 49 studied patients, 36 showed improvement in the FOIS after speech therapy sessions. Regarding possible factors affecting the therapy, statistical analysis showed that deterioration of clinical condition, clinical intercurrences and decreased level of alertness were significant factors for the lack of progress to oral feeding during the speech therapy sessions. The other factors, etiology of disease, age, respiratory condition, time and number of sessions, did not demonstrate statistical significance. However, they did not interfere in improving or worsening the patients' clinical condition. CONCLUSION: there is an effective improvement in feeding by oral intake in patients with neurogenic dysphagia being treated by speech therapy sessions in the hospital wards. However, it cannot be achieved if the patient shows clinical intercurrences and decreased alertness level.

    Full Text Available Introduction : Even though stuttering is probably as old a phenomenon as the human speech itself, the stuttering therapy is still a challenge for the therapist and requires constant searching for new methods. Qigong may prove to be one of them. Aim of the research: The research paper presents the results of an experimental investigation evaluating the usefulness of qigong practice in stuttering therapy. Material and methods: Two groups of stuttering adults underwent 6-month therapy. In group I – the experimental one (n = 11 – the therapy consisted of speech fluency training, psychotherapy and qigong practice. In group II – the control one (n = 12 – it included speech fluency training and psychotherapy. In both groups 2-hour sessions of speech fluency training and psychotherapy were conducted twice a week. Two-hour qigong sessions took place once a week. Results: After 6 months the therapy results were compared with regard to the basic stuttering parameters, such as the degree of speech disfluency, the level of logophobia and speech disfluency symptoms. Improvement was observed in both groups, the beneficial effects, however, being more prominent in the qigong-practising group. Conclusions : Qigong exercises used in the therapy of stuttering people along with speech fluency training and psychotherapy give beneficial effects.

    Extended use of antimycotics in oral candidiasis therapy gives rise to problems related to fungal drug resistance. The aim of this pilot study was to investigate the efficacy of tissue tolerable plasma (TTP) in denture stomatitis patients. It was hypothesised that (I): erythema and (IIa): complaint remission would be accelerated and (IIb): colony forming unit (CFU) reduction would be improved. The halves of the upper jaws of eight patients were randomly assigned to control (nystatin, chlorhexidine and placebo treatment) and test sides (nystatin, chlorhexidine and TTP administered six times each 7 days). The patients and the investigators, who were different from the therapists, were both blinded. Compared to the control sides, the erythema surface was reduced significantly more extensively on the test sides between 2 and 6 weeks of antifungal therapy (P ≤ 0.05). Visual analogue scale values and the frequency of moderate or heavy growth of Candida post-treatment did not differ significantly between both sides (P > 0.05). The primary hypothesis was confirmed, which may be interpreted as an accelerated remission. As drug therapy is usually limited to the time in which signs of infection are present, TTP might help reducing antifungal use. Even though the secondary hypotheses were not confirmed, persistence of Candida might be only colonisation. © 2016 Blackwell Verlag GmbH.

    Patients sometimes discontinue the use of expensive oral anti-cancer drug (OACD) or biological disease-modifying anti-rheumatic drug (bDMARD) therapies early, leading to medication waste if the patient has not used all dispensed medication. To determine the proportion of patients who have unused OACDs or bDMARDs after therapy discontinuation, and the quantity and economic value of these unused medications. Furthermore, patients' reasons for therapy discontinuation and their disposal method for unused medications were determined. In a retrospective follow-up study using a Dutch outpatient pharmacy database, patients (≥18 years) who did not refill an OACD or bDMARD prescription, dispensed between November 2015 and February 2016, within two weeks of the prescription end date were contacted by phone and asked about their unused medication and reasons thereof. The economic value was calculated using Dutch medication prices. Data were descriptively analyzed in STATA13. The database included 1173 patients, of whom 159 likely had discontinued therapy and were contacted. Of these, 88 patients were excluded (39 refilled, 47 missing, and 2 other). Of the 71 patients who had discontinued therapy, 39 (54.9%) had unused medications, comprising 22 OACD users (mean age 63.0 (SD ± 15.9) years, 50.0% female) and 17 bDMARD users (mean age 50.7 (SD ± 13.5) years, 47.1% female). A total of 59 packages were unused, with a total value of €60,341. Unused OACD packages and bDMARD packages had median values of €179 (IQR €24-2487) and €992 (IQR €681-1093), respectively. Patients primarily discontinued therapy due to adverse or insufficient effects. This study illustrates that more than half of patients discontinuing OACD or bDMARD therapies have unused medication. This emphasizes the need for waste-reducing interventions. Copyright © 2018 Elsevier Inc. All rights reserved.

    Oral mucositis is an acute toxicity that occurs in patients submitted to chemoradiotherapy to treat head and neck squamous cell carcinoma. In this study, we evaluated differences in gene expression in the keratinocytes of the oral mucosa of patients treated with photobiomodulation therapy and tried to associate the molecular mechanisms with clinical findings. From June 2009 to December 2010, 27 patients were included in a randomized double-blind pilot study. Buccal smears from 13 patients were obtained at days 1 and 10 of chemoradiotherapy, and overall gene expression of samples from both dates were analyzed by complementary DNA (cDNA) microarray. In addition, samples from other 14 patients were also collected at D1 and D10 of chemoradiotherapy for subsequent validation of cDNA microarray findings by qPCR. The expression array analysis identified 105 upregulated and 60 downregulated genes in our post-treatment samples when compared with controls. Among the upregulated genes with the highest fold change, it was interesting to observe the presence of genes related to keratinocyte differentiation. Among downregulated genes were observed genes related to cytotoxicity and immune response. The results indicate that genes known to be induced during differentiation of human epidermal keratinocytes were upregulated while genes associated with cytotoxicity and immune response were downregulated in the laser group. These results support previous clinical findings indicating that the lower incidence of oral mucositis associated with photobiomodulation therapy might be correlated to the activation of genes involved in keratinocyte differentiation.

    Genital herpes is caused by herpes simplex virus 1 (HSV-1) or 2 (HSV-2). Some infected people experience outbreaks of genital herpes, typically, characterized by vesicular and erosive localized painful genital lesions. To compare the effectiveness and safety of three oral antiviral drugs (acyclovir, famciclovir and valacyclovir) prescribed to suppress genital herpes outbreaks in non-pregnant patients. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the search portal of the World Health Organization International Clinical Trials Registry Platform and pharmaceutical company databases up to February 2014. We also searched US Food and Drug Administration databases and proceedings of seven congresses to a maximum of 10 years. We contacted trial authors and pharmaceutical companies. We selected parallel-group and cross-over randomized controlled trials including patients with recurrent genital herpes caused by HSV, whatever the type (HSV-1, HSV-2, or undetermined), with at least four recurrences per year (trials concerning human immunodeficiency virus (HIV)-positive patients or pregnant women were not eligible) and comparing suppressive oral antiviral treatment with oral acyclovir, famciclovir, and valacyclovir versus placebo or another suppressive oral antiviral treatment. Two review authors independently selected eligible trials and extracted data. The Risk of bias tool was used to assess risk of bias. Treatment effect was measured by the risk ratio (RR) of having at least one genital herpes recurrence. Pooled RRs were derived by conventional pairwise meta-analyses. A network meta-analysis allowed for estimation of all possible two-by-two comparisons between antiviral drugs. A total of 26 trials (among which six had a cross-over design) were included. Among the 6950 randomly assigned participants, 54% (range 0 to 100%) were female, mean age was 35 years (range 26 to 45.1), and the mean number of recurrences per year was 11

    The introduction of new disease-modifying therapies (DMTs) for remitting-relapsing multiple sclerosis (RRMS) has considerably transformed the landscape of therapeutic opportunities for this chronic disabling disease. Unlike injectable drugs, oral DMTs promote patient satisfaction and increase therapeutic adherence. This article reviews the salient features about the mode of action, efficacy, safety, and tolerability profile of approved oral DMTs in RRMS, and reviews their place in clinical algorithms in the Middle East and North Africa (MENA) region. A systematic review was conducted using a comprehensive search of MEDLINE, PubMed, Cochrane Database of Systematic Reviews (period January 1, 1995-January 31, 2018). Additional searches of the American Academy of Neurology and European Committee for Treatment and Research in Multiple Sclerosis abstracts from 2012-2017 were performed, in addition to searches of the Food and Drug Administration and European Medicines Agency websites, to obtain relevant safety information on these DMTs. Four oral DMTs: fingolimod, teriflunomide, dimethyl fumarate, and cladribine have been approved by the regulatory agencies. Based on the number needed to treat (NNT), the potential role of these DMTs in the management of active and highly active or rapidly evolving RRMS is assessed. Finally, the place of the oral DMTs in clinical algorithms in the MENA region is reviewed.

    In Ceara State in northeastern Brazil in 1986 infant mortality reached 110-139 per 1000 live births, and 50% of those deaths were due to diarrhea and dehydration. Diarrheal deaths can be prevented by oral rehydration therapy (ORT), which replaces lost fluids and electrolytes with oral rehydration salts (ORS) and water. ORT was known in the 1830s, but only in the 1960s was the importance of sugar, which increases the body's ability to absorb fluid some 25 times, realized. In northeastern Brazil access to ORT has been severely limited by poverty, official incompetence, and bureaucratic restrictions. In 1984 a 2-year research project was initiated in the village of Pacatuba to test the theory that mobilizing and training popular healers in ORT would 1) increase awareness and use of ORS, 2) promote continued feeding during diarrhea, 3) increase breast feeding, and 4) reduce the use of costly and nonindicated drugs. 46 popular healers, including rezadeiras and oradores (prayers), Umbandistas (priests), espiritas (mediums), an herbalist, and a lay doctor, were recruited and trained. Most of these people practiced a mixture of folk medicine and religion and were highly respected in the community. For purposes of survey, Pacatuba was divided into 3 groups, each containing houses at 4 different income levels. The mothers in 204 Group 1 homes were interviewed concerning ORT and diarrhea-related knowledge before intervention, and 226 households in Group 2 were interviewed after intervention. The healers were taught the basic biomedical concept of rehydration and how to mix the ORS -- 7 bottle cap-fulls of sugar and 1 of salt in a liter of unsweetened traditional tea. The healers were also taught how to use the World Health Organization's (WHO) ORS packets (2% glucose, 90 mmol/1 of sodium chloride, 1.5 gm potassium chloride, and 2.9 gm sodium bicarbonate) for cases of moderate to severe dehydration. In addition, the healers were taught the 5 basic health messages: give ORS

    Full Text Available Background: Candida isolate is easily sampled from oral cavity by swabbing directly on the candidiasis lesion, to be smeared onto slides for direct examination or cultured in a growth medium. This method is by far the gold standard for defining candidiasis diagnosis. However it is difficult to apply on sensitive patients and almost impossible on patients showing no clinical appearance of oral candidiasis. AIDS patients are very prone to candida infection and have a tendency of repetitive infection involving mixed species. As many candida species show different susceptibility to anti-fungal agents, it is necessary to identify the species causing the infection in the management of oral candidiasis. Oral rinse is a suggested method to obtain candida isolate to be cultured for further analysis such as species identification. This method is simple and less risky on infection transmission as less tools are required in the procedure. Purpose: This study aimed to assess the application of oral rinse as an alternative method to culture Candida isolate from AIDS patients. Methods: A cross-sectional observative study was conducted in HIV/AIDS in-Patient Facility of Intermediate Care Unit for Infection Disease, Dr. Soetomo Hospital Surabaya. Fourteen stadium 4 AIDS patients matching criteria were swabbed on 1/3-posterior of the tongue, and then given 10 ml phosphate buffer saline to rinse vigorously for 15 seconds. Both specimens were cultured on Sabouraud’s dextrose agar and colony growth was observed. Results: Candida colonies were able to grow from all 14 isolates (100% by both methods. Qualitatively, cultures from oral rinse specimens were more populated than cultures from swab specimens. Conclusion: Oral rinse is an applicable technique to obtain Candida species isolate. This technique is safe, easy, non-invasive, and needs less tools therefore less risky for HIV transmission.Latar belakang: Isolat Candida mudah diambil dengan cara mengusap lesi

    Statement of Problem: Fixed orthodontic appliances in the oral cavity make tooth cleaning procedures more complicated. Objectives: This study aimed to compare the efficacy of computerized oral hygiene instruction with verbal technique among fixed orthodontic patients referred to the evening clinic of Orthodontics of Shiraz Dental School. Materials and Methods: A single-blind study was performed in Orthodontic Department of Shiraz, Islamic Republic of Iran, from January to May 2015 following the demonstrated exclusion and inclusion criteria. The sample size was considered 60 patients with 30 subjects in each group. Bleeding on probing and plaque indices and dental knowledge were assessed in the subjects to determine pre-intervention status. A questionnaire was designed for dental knowledge evaluation. The patients were randomly assigned into the computerized and verbal groups. Three weeks after the oral hygiene instruction, indices of bleeding on probing and plaque index and the dental knowledge were evaluated to investigate post-intervention outcome. The two groups were compared by chi-square and student t tests. The pre- and post-intervention scores in each group were compared using paired t-test. Results: In the computerized group, the mean score for plaque index and bleeding on probing index was significantly decreased while dental health knowledge was significantly increased after oral hygiene instruction, in contrast to the verbal group. Conclusions: Within the limitations of the current study, computerized oral hygiene instruction is proposed to be more effective in providing optimal oral health status compared to the conventional method in fixed orthodontic patients.

    Development of an acute oral toxicity test with a terrestrial-phase amphibian was considered necessary to remove the uncertainty within the field of agrochemical risk assessments. The bullfrog (Lithobates catesbeianus) was selected for use as it is a representative of the family Ranidae and historically this species has been used as an amphibian test model species. Prior to definitive study, oral gavage methods were developed with fenthion and tetraethyl pyrophosphate. Dimethoate and malathion were subsequently tested with both male and female juvenile bullfrogs in comprehensive acute oral median lethal dose (LD50) studies. Juvenile bullfrogs were administered a single dose of the test article via oral gavage of a single gelatin capsule of dimethoate technical (dimethoate) or neat liquid Fyfanon ® Technical (synonym malathion), returned to their respective aquaria, and monitored for survival for 14 d. The primary endpoint was mortality, whereas behavioral responses, food consumption, body weight, and snout-vent length (SVL) were used to evaluate indications of sublethal toxicity (secondary endpoints). Acute oral LD50 values (95% fiducial interval) for dimethoate were 1459 (1176-1810, males) and 1528 (1275-1831, females), and for malathion they were 1829 (1480-2259, males) and 1672 (1280-2183, females) mg active substance/kg body weight, respectively. Based on the results of these studies, the methodology for the acute oral gavage administration of test items to terrestrial-phase amphibians was demonstrated as being a practical method of providing data for risk assessments.

    We have proposed and validated the hamster cheek pouch model of oral cancer for BNCT studies separately. We herein report the first evidence of the usefulness of BNCT for the treatment of oral cancer in an experimental model. We assessed the response of hamster cheek pouch tumors, precancerous tissue and normal oral tissue to BPA-mediated BNCT employing the thermalized epithermal beam of the RA-6 Reactor at the Bariloche Atomic Center. BNCT leads to complete remission by 15 days post-treatment in 78% of tumors and partial remission in a further 13% of tumors with virtually no damage to normal tissue. (author)

    Fixed orthodontic appliance (FOA) increases the cariogenic microorganisms of mouth including candida. The aim was to evaluate the pharmacodynamic effects of some antibacterial drugs in combination with most applicable antifungal agents on candida isolated from patients with FOA. Three antifungal agents (amphotericin B (AMB), ketoconazole (KET), and itraconazole (ITZ)) and three antibacterial drugs (ciprofloxacin (CIP), doxycycline (DOX), and metronidazole (MET)) with serial concentrations have been used and microdilution broth method has been done for single and combination therapy, then fungal growth was assessed spectrophotometrically, and the combinations were evaluated by bliss independent analysis. According to bliss independent interaction, the synergistic interactions depended on Δ E values that showed the best for CIP was with AMB (Δ E = 55.14) followed with KET (Δ E = 41.23) and lastly ITR (Δ E = 39.67) at CIP = 150 mg/L. DOX was optimal with KET (Δ E = 42.11) followed with AMB (Δ E = 40.77) and the lowest with ITR (Δ E = 9.12) at DOX = 75 mg/L. MET is the best with AMB (Δ E = 40.95) and then with ITR (Δ E = 35.45) and finally KET (Δ E = 15.15) at MET 200 mg/L. Moreover, usage of higher concentrations of antibacterial agents revealed inhibitory effects. This study uncovers the optimum antibiotic combination therapy against cariogenic candida with FOA by usage of low therapeutic concentrations.

    : To investigate perioperative and postoperative bleeding, complications in patients under therapy with anticoagulant or antiplatelet drugs submitted to oral surgery. To evaluate the risk of bleeding and safety for dental surgery, a retrospective chart review was performed. Medical and dental records of patients taking oral antithrombotic drugs undergoing dental surgery between 2010 and 2015 were reviewed. Results were statistically analyzed using Fisher's exact test, t test or the χ test. One hundred and seventy-nine patients underwent 293 surgical procedures. A total of eight cases of perioperative and 12 episodes of postoperative bleeding were documented. The complications were generally managed with local measures and did not require hospitalization. We found significant association of postoperative hemorrhage with increased perioperative bleeding (P = 0.043) and combination of anticoagulant and antiplatelet therapy (P bleeding is 8.8 times bigger than procedures without perioperative bleeding. Dental surgery in patients under antithrombotic therapy might be carried out without altering the regimen because of low risk of perioperative and postoperative bleeding. However, patients with increased perioperative bleeding should be closely followed up because of postoperative complications risk.

    Oral iron is commonly prescribed to older patients with suspected or confirmed iron-deficiency anaemia; however, few studies have examined the effectiveness of oral iron therapy in the real world in this population. We therefore determined the prevalence of iron deficiency in older people prescribed oral iron, examined the response mounted to therapy and ascertained predictors of response to oral iron. We analysed a routinely collected, linked dataset from older patients who had undergone inpatient rehabilitation between 1999 and 2011. An initial analysis examined patients within this cohort who were prescribed iron after rehabilitation and derived three groups based upon their ferritin and transferrin indices: probably, possibly and not iron deficient. A second analysis compared pre- and post-treatment haemoglobin to determine the degree of response to iron therapy across each category of deficiency. Finally, patient demographics, linked biochemistry data and comorbid disease based on International Classification of Disease (ICD-10) codes from previous hospital admissions were used in regression modelling to evaluate factors affecting response to therapy. A total of 490 patients were prescribed oral iron within 90 days of rehabilitation discharge. Of these, 413 (84 %) had iron indices performed; 94 (23 %) were possibly deficient, 224 (54 %) were probably deficient, and 95 (23 %) were not deficient. Of the 490 patients, 360 had both pre- and post-treatment haemoglobin data and iron indices; probably deficient patients mounted a slightly greater response to oral iron (17 vs. 12 g/L for not deficient; p < 0.05). Only pre-treatment haemoglobin, mean cell volume and lower gastrointestinal pathology were significant predictors of a response to oral iron therapy. Notably, acid-suppressant use was not a predictor of response. We conclude that many older patients are exposed to oral iron without good evidence of either iron deficiency or a significant response to

    Rapid diagnostic tests (RDT) for HIV infection have high sensitivity and specificity, but in the setting of longstanding antiretroviral therapy (ART), can give false results that can lead to misinterpretation, confusion and inadequate management. The objective of this study was to evaluate the proportion of falsely negative results of a RDT performed on oral fluid in HIV-infected children on longstanding ART. One hundred and twenty-nine children with known HIV infection and receiving ART were recruited from the HIV Clinic at the Harare Central Hospital, Zimbabwe. HIV testing was performed on oral fluid and on finger-stick blood. Children included in the study had a median age of 12 years (IQR 10-14) and 67 (51.9%) were female. Median age at HIV diagnosis was 5 years (IQR 3-6) and the median time on ART was 6.3 years (IQR 4.3-8.1). The oral fluid test was negative in 11 (8.5%) patients and indeterminate in 2 (1.6%). Finger-stick blood test was negative in 1 patient. Patients with a negative oral fluid test had a higher CD4 cell count (967 vs. 723 cells/mm 3 , p  = 0.016) and a longer time on ART (8.5 vs. 6 years, p  = 0.016). This study found that a substantial proportion of false-negative HIV test results in children on longstanding ART when using an oral fluid test. This could lead to misinterpretation of HIV test results and in the false perception of cure or delayed diagnosis.

    The aim of this study was to design a new orally disintegrating tablet (ODT) that has high tablet hardness and a fast oral disintegration rate using a new preparation method. To obtain rapid disintegration granules (RDGs), a saccharide, such as trehalose, mannitol, or lactose, was spray-coated with a suspension of corn starch using a fluidized-bed granulator (suspension method). As an additional disintegrant, crospovidone, light anhydrous silicic acid, or hydroxypropyl starch was also included in the suspension. The RDGs obtained possessed extremely large surface areas, narrow particle size distribution, and numerous micro-pores. When tabletting these RDGs, it was found that the RDGs increased tablet hardness by decreasing plastic deformation and increasing the contact frequency between granules. In all tablets, a linear relationship was observed between tablet hardness and oral disintegration time. From each linear correlation line, a slope (D/H value) and an intercept (D/H(0) value) were calculated. Tablets with small D/H and D/H(0) values could disintegrate immediately in the oral cavity regardless of the tablet hardness and were considered to be appropriate for ODTs. Therefore, these values were used as key parameters to select better ODTs. Of all the RDGs prepared in this study, mannitol spray-coated with a suspension of corn starch and crospovidone (2.5:1 w/w ratio) showed most appropriate properties for ODTs; fast in vivo oral disintegration time, and high tablet hardness. In conclusion, this simple method to prepare superior formulations for new ODTs was established by spray-coating mannitol with a suspension of appropriate disintegrants.

    Numerous experimental and clinical materials about expediency of the use of physical methods for lowering of frequency and heaviness of complications of radial therapy are reviewed. One of such methods, possessing most expressed radioprotection ability, is low intensity laser radiation. Some of the authors demonstrated that use of this method move aside the time of appearance of early radial reactions. Preliminary local use of laser irradiation (λ = 510 nm) permits to avoid of development of epidermis disease and such radial reactions as ulcer and skin fibrosis in cancer patients after neutron-photon therapy. There are good results of application of ultraviolet irradiation in the region of action of ionizing radiation in the case of medical treatment of skin cancer. Low frequency magnetic field can reduce the expression of radial reactions

    Full text of publication follows. Aim: the salivary glands (SG) constitute a risk organ during a radioiodine therapy of thyroid. A possible side effect is xerostomia. This study investigates whether repeated rinsing of the mouth with water during radioiodine therapy significantly extracts I-131 from the circuit between saliva and the gastrointestinal tract, and thus whether radiation exposure of the patient's SG is reduced. Methods: the control group consisted of 45 patients, ages 32 to 81 years, (mean 62 years, 8 male, 37 female), and received radioiodine therapy without rinsing their mouths. An intervention group of 42 patients, ages 36 to 88 years, (mean 61 years, 8 male, 34 female), with a benign or malignant thyroid disease, were asked 15-17 hours after capsule administration to rinse their mouths hourly with water for the next two days. The intervention group (n = 42) was divided into three groups. A low-risk group (n = 22) received between 0.4 and 1.0 GBq I-131 (mean 0.746), a medium risk group (n = 15) between 1.2 and 2.0 GBq (mean 1.783), and the high-risk group (n = 5) between 3.0 and 6.0 GBq (mean 3.600) respectively. To assess the function of the SG, scintigrams were performed prior to and 3 months after the radioiodine therapy. The estimation of the activity in the gastrointestinal tract was performed using whole-body scintigraphy on the day of release. Both, the SG and the whole body (WB) scintigraphies were evaluated using the region-of-interest technique. Furthermore, the activity of the collected saliva was quantified using a calibrated well-type detector. Results: the mean values of the activity extracted into the water-saliva mixture were 0.72% ± 0.3% and 0.14% ± 0.05% of the applied dose on the first and second day after capsule administration respectively. The analysis of the SG scintigrams of the low and medium risk groups showed no significant decrease in salivary gland function. Only in the high-risk group a significant loss of

In the first decade of life, patients usually develop a decrease in visual acuity. Long-term visual outcomes can be poor due to the limited number of known successful treatments. Purpose: The purposes of this study were to present, for the first time, a p.Arg197Cys missense mutation in the RS1 gene (OMIM: 300839 in a four-generation Italian family with RS1 and to examine the clinical response to the treatment with acetazolamide tablets alone or in combination with dorzolamide eye drops as assessed by spectral-domain optical coherence tomography (SD-OCT. Methods: Eleven individuals, including two brothers with RS1 (patients 1 and 2, underwent a full medical history examination and a comprehensive ocular assessment that involved SD-OCT, fluorescein angiography, electroretinography and DNA analysis. Each RS1 patient received oral acetazolamide (375 mg daily during the first three months. Thereafter, patient 1 continued only with dorzolamide eyedrops three times a day for a period of three months, while patient 2 spontaneously stopped both medications. Results: Sequence analysis of the RS1 gene identified a hemizygous c.589C>T (p.Arg197Cys missense mutation in exon 6, which has not been previously reported in an Italian family. A different response to the medical therapy was observed in the four eyes of the two affected brothers hemizygous for

    Full Text Available Late diagnosis resulting in late treatment and locoregional failure after surgery are the main causes of death in patients with oral squamous cell carcinomas (SCCs. Actually, exfoliative cytology is increasingly used for early detection of oral cancer and has been the subject of intense research over the last five years. Significant advances have been made both in relation to screening and evaluation of precursor lesions. As this noninvasive procedure is well tolerated by patients, more lesions may be screened and thus more oral cancers may be found in early, curable stages. Moreover, the additional use of DNA image cytometry is a reasonable tool for the assessment of the resection margins of SCC. DNA image cytometry could help to find the appropriate treatment option for the patients. Finally, diagnostic DNA image cytometry is an accurate method and has internationally been standardized. In conclusion, DNA image cytometry has increasing impact on the prevention, diagnostic, and therapeutical considerations in head and neck SCC.

    Patients undergoing radiation therapy for the head and neck are susceptible to a significant and often abrupt deterioration in their oral health. The oral morbidities of radiation therapy include but are not limited to an increased susceptibility to dental caries and periodontal disease. They also include profound and often permanent functional and sensory changes involving the oral soft tissue. These changes range from oral mucositis experienced during and soon after treatment, mucosal opportunistic infections, neurosensory disorders, and tissue fibrosis. Many of the oral soft tissue changes following radiation therapy are difficult challenges to the patients and their caregivers and require life-long strategies to alleviate their deleterious effect on basic life functions and on the quality of life. We discuss the presentation, prognosis, and management strategies of the dental structure and oral soft tissue morbidities resulting from the administration of therapeutic radiation in head and neck patient. A case for a collaborative and integrated multidisciplinary approach to the management of these patients is made, with specific recommendation to include knowledgeable and experienced oral health care professionals in the treatment team. © 2017 The Authors.

    Setting and design: A cross sectional descriptive survey was conducted among 158 staff nurses working in oncology related areas from 4 different hospitals of Dakshina Kannada district and Udupi district of Karnataka state, India. Statistical Analysis: descriptive and inferential statistics was used by using SPSS 16 version. Results: Majority 81 (51.3% of the staff nurses had poor knowledge of oral care in cancer patients whereas 87 (55.1% reported that knowledge acquired through basic education in oral care is not sufficient. Most of the staff nurses 115 (72.8% did not receive basic education in oral care of cancer patients. There was significant association between knowledge and variables such as designation (.005, years of work experience (.040 and years of experience in cancer wards (.000 at 0.05 levels. Conclusion: Lack of knowledge suggest the need to develop and implement continuing nursing education programs on oral care specifically for patients receiving cancer treatments, for improving knowledge of staff nurses′ in order to render comprehensive care to the patients. This study also recommends the importance of inclusion of cancer patient specific oral care in the curriculum which can enhance competency of the qualified nurses in cancer wards.

    Full Text Available Purpose of the study. This study was to evaluate the use of buccal fat pad as an interpositioning material in surgical management of oral sub mucous fibrosis. Materials and methods. A series of 8 cases with proven oral sub mucous fibrosis, with mouth opening less than 20 mm, involving the buccal mucosa were treated surgically in the Department of Oral and Maxillofacial Surgery, College of Dental Surgery, Saveetha University, Chennai. Pedicled buccal fat pad was used as an interpositioning material to cover the raw areas in the oral cavity after incision and release of fibrous bands. Results. In 8 patients, the range of pre operative mouth opening was 3–18 mm (mean 14 mm. As the result of the successful surgical procedure, the size of the intra operative mouth opening was ranged from 25–38 mm (mean 33.25 mm. The patients were discharged 5–7 days after the operation. The range of the mouth opening at this time was 25–36 mm (mean 30.63 mm. The results were evaluated using student’s t test and found to be statistically significant. The pedicled grafts took up uneventfull.

    Full Text Available A large body of evidence suggests that thyroid hormones (THs are beneficial for the treatment of cardiovascular disorders. We have shown that 3 days of triiodo-L-thyronine (T3 treatment in myocardial infarction (MI rats increased left ventricular (LV contractility and decreased myocyte apoptosis. However, no clinically translatable protocol is established for T3 treatment of ischemic heart disease. We hypothesized that low-dose oral T3 will offer safe therapeutic benefits in MI.Adult female rats underwent left coronary artery ligation or sham surgeries. T3 (~6 μg/kg/day was available in drinking water ad libitum immediately following MI and continuing for 2 month(s (mo. Compared to vehicle-treated MI, the oral T3-treated MI group at 2 mo had markedly improved anesthetized Magnetic Resonance Imaging-based LV ejection fraction and volumes without significant negative changes in heart rate, serum TH levels or heart weight, indicating safe therapy. Remarkably, T3 decreased the incidence of inducible atrial tachyarrhythmias by 88% and improved remodeling. These were accompanied by restoration of gene expression involving several key pathways including thyroid, ion channels, fibrosis, sympathetic, mitochondria and autophagy.Low-dose oral T3 dramatically improved post-MI cardiac performance, decreased atrial arrhythmias and cardiac remodeling, and reversed many adverse changes in gene expression with no observable negative effects. This study also provides a safe and effective treatment/monitoring protocol that should readily translate to humans.

    Photodynamic therapy (PDT) is a light-based modality that shows promise for adaptation and implementation as a cancer treatment technology in resource-limited settings. In this context PDT is particularly well suited for treatment of pre-cancer and early stage malignancy of the oral cavity, that present a major global health challenge, but for which light delivery can be achieved without major infrastructure requirements. In recent reports we demonstrated that a prototype low-cost batterypowered 635nm LED light source for ALA-PpIX PDT achieves tumoricidal efficacy in vitro and vivo, comparable to a commercial turn-key laser source. Here, building on these reports, we describe the further development of a prototype PDT device to enable intraoral light delivery, designed for ALA- PDT treatment of precancerous and cancerous lesions of the oral cavity. We evaluate light delivery via fiber bundles and customized 3D printed light applicators for flexible delivery to lesions of varying size and position within the oral cavity. We also briefly address performance requirements (output power, stability, and light delivery) and present validation of the device for ALA-PDT treatment in monolayer squamous carcinoma cell cultures.

    Full Text Available Oral rehydration salt (ORS treatment in young children with acute diarrhoea (AD has contributed to decrease mortality associated with dehydration although effective strategies to reduce morbidity associated with this disease are required. The aim of this study was to evaluate the diarrhoea duration when using combined colloidal bismuth hydroxide gel (CBHG and oral rehydration salt treatment compared with ORS therapy in children with AD. We designed a double-blind, randomised prospective study with treatment and control groups. Patients aged one to 12 years, with no prior pathology and with AD of less than 48 h were included. The Chi-squared and Mann-Whitney tests were used, as well as the Cox proportional hazards model and the Kaplan-Meier estimator. Patients were randomised into an ORS and CBHG treatment group and a control group for ORS plus placebo. (Average age: 3.2 years. The result of the post-treatment evaluation with respect to the average duration of AD was 25.5 h for the treated group vs. 41.5 h for the control group (p = 0.015. The average number of stools was 4.8 in the treated group and 8.2 in the control group (p = 0.032. We conclude that the use of CBHG plus ORS significantly reduced the duration of AD, the number of stools and the percentage of children with persistent AD after 24 h of treatment compared to the control group. AD remitted almost twice as fast in patients treated with CBHG and ORS compared to those who received ORS plus placebo.

    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 single-center retrospective study of prospectively collected data was aimed at comparing the clinical outcomes of positron emission tomography/computed tomography (PET/CT) for patients with oral cavity squamous cell carcinoma (OSCC) with symptomatic recurrences identified by PET/CT imaging following adjuvant therapy (Group A) versus those of cases with asymptomatic recurrences diagnosed through periodic post-adjuvant therapy PET/CT surveillance (Group B). We also sought to establish the priority of salvage therapy in the two study groups. We identified 111 patients with advanced resected OSCC who developed recurrences following adjuvant therapy (51 in Group A and 60 in Group B). Histopathology served as the gold standard for recurrent lesions. The impact of post-adjuvant therapy PET/CT surveillance was examined with Kaplan-Meier curves and Cox proportional hazards regression models. The 2-year DSS and OS rates were marginally or significantly higher in Group B than in Group A (P = 0.073 and P = 0.025, respectively). Time-dependent ROC curve analysis demonstrated that the optimal cutoff values for time to positive PET/CT findings in relation to OS were 12 months for Group A and 9 months for Group B, respectively. Independent risk factors identified in multivariate analyses were used to devise two prognostic scoring systems for 2-year DSS and OS in each study group (all P < 0.001). Scheduled periodic PET/CT surveillance is a valuable tool for early detection of recurrent lesion(s) in asymptomatic OSCC patients who bear risk factors for disease recurrence. The presence of clinical symptoms and a short time to positive PET/CT findings were adverse prognostic factors for clinical outcome in patients with advanced OSCC. The priority of salvage therapy is discussed in each patient subgroup according to the devised prognostic scoring systems. (orig.)

Intravenous iron has shown clinical benefit compared to oral iron therapy. Aim: This study aimed to compare health care outcomes and costs after oral vs intravenous iron treatment for IBD patients with iron deficiency or iron deficiency anemia (ID/A in Germany. Methods: IBD patients with ID/A were identified by ICD-10-GM codes and newly commenced iron treatment via ATC codes in 2013 within the InGef (formerly Health Risk Institute research claims database. Propensity score matching was performed to balance both treatment groups. Non-observable covariates were adjusted by applying the difference-in-differences (DID approach. Results: In 2013, 589 IBD patients with ID/A began oral and 442 intravenous iron treatment. After matching, 380 patients in each treatment group were analyzed. The intravenous group had fewer all-cause hospitalizations (37% vs 48% and ID/A-related hospitalizations (5% vs 14% than the oral iron group. The 1-year preobservation period comparison revealed significant health care cost differences between both groups. After adjusting for cost differences by DID method, total health care cost savings in the intravenous iron group were

    Objective: to verify if the use of InGaAIP laser with 685 nm wave length can reduce the xerostomy incidence, the oral mucositis severity and the pain related to mucositis in patients with head and neck cancer submitted to radiotherapy. Objective: sixty patients presenting head and neck carcinoma were submitted to radiotherapy with daily doses of 1.8 to 2.0 Gy and a final dose of 45 to 72 Gy. The salivary volume was evaluated in the first and fifteenth days, at the end of the treatment and after 15 and 30 days. The oral mucositis was evaluated on a weekly basis. Twenty-nine patients were submitted to radiotherapy without laser and 31 were submitted to radiotherapy and laser with daily doses of 2 joules/cm 2 in predetermined areas of the oral mucosa and the parotid and submandibular glands. Results: in the group submitted to radiotherapy and laser the incidence of mucositis (p < 0.001) and pain (p < 0.016) was significantly lower and the salivary volume (p < 0.001) was kept higher during and after the treatment. Conclusion: the group of patients submitted to radiotherapy and laser had lower incidence of xerostomy, oral mucositis and pain when compared to the group treated with radiotherapy without laser, producing statistically significant results.

    Full Text Available Iron overload in hemoglobinopathies is secondary to blood transfusions, chronic hemolysis, and increased iron absorption and leads to tissue injury requiring the early use of chelating agents. The available agents are parenteral deferoxamine and oral deferiprone and deferasirox. There are limited data on the safety and efficacy of deferiprone at a very young age. The aim of our study was the presentation of data regarding the use of oral solution of deferiprone in 9 children (mean age 6.5, range 2–10 with transfusion dependent hemoglobinopathies (6 beta thalassemia major, 1 thalassemia intermedia, and 2 sickle cell beta thalassemia. The mean duration of treatment was 21.5 months (range 15–31. All children received the oral solution without any problems of compliance. Adverse reactions were temporary abdominal discomfort and diarrhea (1 child, mild neutropenia (1 child that resolved with no need of discontinuation of treatment, and transient arthralgia (1 child that resolved spontaneously. The mean ferritin levels were significantly reduced at the end of 12 months (initial 2440 versus final 1420 μg/L, . This small study shows that oral solution of deferiprone was well tolerated by young children and its use was not associated with major safety concerns. Furthermore, it was effective in decreasing serum ferritin.

    Disease-modifying therapies (DMTs) are indicated to reduce relapse rates and slow disease progression for relapsing-remitting multiple sclerosis (MS) patients when taken as prescribed. Nonadherence or non-persistence in the real-world setting can lead to greater risk for negative clinical outcomes. Although previous research has demonstrated greater adherence and persistence to oral DMTs compared with injectable DMTs, comparisons among oral DMTs are lacking. To compare adherence, persistence, and time to discontinuation among MS patients newly prescribed the oral DMTs fingolimod, dimethyl fumarate, or teriflunomide. This retrospective study used MarketScan Commercial and Medicare Supplemental claims databases. MS patients with ≥ 1 claim for specified DMTs from April 1, 2013, to June 30, 2013, were identified. The index drug was defined as the first oral DMT within this period. To capture patients newly initiating index DMTs, patients could not have a claim for their index drugs in the previous 12 months. Baseline characteristics were described for patients in each treatment cohort. Adherence, as measured by medication possession ratio (MPR) and proportion of days covered (PDC); persistence (30-day gap allowed); and time to discontinuation over a 12-month follow-up period were compared across treatment cohorts. Adjusted logistic regression models were used to examine adherence, and Cox regression models estimated risk of discontinuation. 1,498 patients newly initiated oral DMTs and met study inclusion criteria: fingolimod (n = 185), dimethyl fumarate (n = 1,160), and teriflunomide (n = 143). Patients were similar across most baseline characteristics, including region, relapse history, and health care resource utilization. Statistically significant differences were observed across the treatment cohorts for age, gender, previous injectable/infused DMT use, and comorbidities. Adherence and time to discontinuation were adjusted for age, gender, region, previous oral

    Meibomian gland dysfunction (MGD) is a common clinical problem that is often associated with evaporative dry eye disease. Alterations of the lipids of the meibomian glands have been identified in several studies of MGD. This prospective, observational, open-label clinical trial documents the improvement in both clinical signs and symptoms of disease as well as spectroscopic characteristics of the meibomian gland lipids after therapy with topical azithromycin ophthalmic solution and oral doxycycline treatment. Subjects with symptomatic MGD were recruited. Signs of MGD were evaluated with a slit lamp. Symptoms of MGD were measured by the response of subjects to a questionnaire. Meibum lipid-lipid interaction strength, conformation, and phase transition parameters, and meibum protein content were measured using Fourier transform infrared spectroscopy and principal component analysis. Terpenoids, short-chain CH3 moieties, lipid oxidation, wax, cholesterylesters and glycerides were measured with a proton nuclear magnetic resonance (H-NMR) spectrometer. Topical therapy with azithromycin and oral therapy with doxycycline relieved signs and symptoms and restored the lipid properties of the meibomian gland secretion toward normal. Compared with 4 weeks of azithromycin treatment reported in our previous study, oral doxycycline treatment was slightly less effective in improving foreign body sensation and the signs of plugging and secretion. In subjects with clinical evidence of MGD, changes in ordering of the lipids and phase transition temperature were brought closer to normal with azithromycin treatment than doxycycline treatment. Treatment with doxycycline but not azithromycin restored the Fourier transform infrared spectroscopy-principal component analysis scores and relative area of the H-NMR resonance at 1.26 ppm. Both doxycycline and azithromycin treatment restored the levels of the relative areas of the H-NMR resonance at 5.2 and 7.9 ppm to normal levels. The levels

    Despite the accessibility of the oral cavity to clinical examination, delays in diagnosis of oral and oropharyngeal carcinoma (OOPC) are observed in a large majority of patients, with negative impact on prognosis. Diagnostic aids might help detection and improve early diagnosis, but there remains little robust evidence supporting the use of any particular diagnostic technology at the moment. The aim of the present feasibility first-in-human study was to evaluate the preliminary diagnostic validity of a novel technology platform based on dielectrophoresis (DEP). DEP does not require labeling with antibodies or stains and it is an ideal tool for rapid analysis of cell properties. Cells from OOPC/dysplasia tissue and healthy oral mucosa were collected from 57 study participants via minimally-invasive brush biopsies and tested with a prototype DEP platform using median membrane midpoint frequency as main analysis parameter. Results indicate that the current DEP platform can discriminate between brush biopsy samples from cancerous and healthy oral tissue with a diagnostic sensitivity of 81.6% and a specificity of 81.0%. The present ex vivo results support the potential application of DEP testing for identification of OOPC. This result indicates that DEP has the potential to be developed into a low-cost, rapid platform as an assistive tool for the early identification of oral cancer in primary care; given the rapid, minimally-invasive and non-expensive nature of the test, dielectric characterization represents a promising platform for cost-effective early cancer detection.

    . The resulting food-borne peptides have recently been shown to be potential activators of microbial autolysis. The main question that needs to be answered in order to verify the hypothesis is whether oral proteases are able (and to what extent) to lyse/mediate lysis of intestinal microorganisms in situ. Methods based on up-to-date molecular biology techniques to allow investigation of the influence of exogenous proteases on microbial lysis processes in vivo (in the intestines) need to be developed. Research testing of this hypothesis may have an important impact in development of novel preparations for the systemic enzyme therapy.

    Purpose: To evaluate the therapeutic results and histopathological effects of treatment with thermochemoradiation therapy using superselective intra-arterial infusion via the superficial temporal and occipital arteries for N3 cervical lymph node metastases of advanced oral cancer. Methods and Materials: Between April 2005 and September 2010, 9 patients with N3 cervical lymph node metastases of oral squamous cell carcinoma underwent thermochemoradiation therapy using superselective intra-arterial infusion with docetaxel (DOC) and cisplatin (CDDP). Treatment consisted of hyperthermia (2-8 sessions), superselective intra-arterial infusions (DOC, total 40-60 mg/m 2 ; CDDP, total 100-150 mg/m 2 ) and daily concurrent radiation therapy (total, 40-60 Gy) for 4-6 weeks. Results: Six of 9 patients underwent neck dissection 5-8 weeks after treatment. In four of these 6 patients, all metastatic lymph nodes, including those at N3, were grade 3 (non-viable tumor cells present) or grade 4 (no tumor cells present) tumors, as classified by the system by Shimosato et al (Shimosato et al Jpn J Clin Oncol 1971;1:19-35). In 2 of these 6 patients, the metastatic lymph nodes were grade 2b (destruction of tumor structures with a small amount of residual viable tumor cells). The other 3 patients did not undergo neck dissection due to distant metastasis after completion of thermochemoradiation therapy (n=2) and refusal (n=1). The patient who refused neck dissection underwent biopsy of the N3 lymph node and primary sites and showed grade 3 cancer. During follow-up, 5 patients were alive without disease, and 4 patients died due to pulmonary metastasis (n=3) and noncancer-related causes (n=1). Five-year survival and locoregional control rates were 51% and 88%, respectively. Conclusions: Thermochemoradiation therapy using intra-arterial infusion provided good histopathologic effects and locoregional control rates in patients with N3 metastatic lymph nodes. However, patients with N3 metastatic

It reduces bone resorption by inhibiting mature active osteoclasts and increases renal calcium excretion. It is used in the management of postmenopausal osteoporosis, Paget's disease of bone, and malignancy-associated hypercalcemia. Synthetic and recombinant calcitonin preparations are available; both have similar pharmacokinetic and pharmacodynamic profiles. As calcitonin is a peptide, the traditional method of administration has been parenteral or intranasal. This hinders its clinical use: adherence with therapy is notoriously low, and withdrawal from clinical trials has been problematic. An oral formulation would be more attractive, practical, and convenient to patients. In addition to its effect on active osteoclasts and renal tubules, calcitonin has an analgesic action, possibly mediated through β-endorphins and the central modulation of pain perception. It also exerts a protective action on cartilage and may be useful in the management of osteoarthritis and possibly rheumatoid arthritis. Oral formulations of calcitonin have been developed using different techniques. The most studied involves drug-delivery carriers such as Eligen® 8-(N-2hydroxy-5-chloro-benzoyl-amino-caprylic acid (5-CNAC (Emisphere Technologies, Cedar Knolls, NJ. Several factors affect the bioavailability and efficacy of orally administered calcitonin, including amount of water used to take the tablet, time of day the tablet is taken, and proximity to intake of a meal. Preliminary results looked promising. Unfortunately, in two Phase III studies, oral calcitonin (0.8 mg with 200 mg 5-CNAC, once a day for postmenopausal osteoporosis and twice a day for osteoarthritis failed to

    Purpose: Dental extraction is a routine part of clinical dental practice. For this reason, understanding the way how students’ extraction knowledge and skills development are important. Problem Statement and Objectives: To date, there is no accredited statement about the most effective method for the teaching of exodontia to dental students. Students have different abilities and preferences regarding how they learn and process information. This is defined as learning style. In this study, the effectiveness of active learning in the teaching of preclinical oral surgery was examined. The personality type of the groups involved in this study was determined, and the possible effect of personality type on learning style was investigated. Method: This study was undertaken over five years from 2011 to 2015. The sample consisted of 115 students and eight staff members. Questionnaires were submitted by 68 students and all eight staff members involved. Three measures were used in the study: The Index of Learning Styles (Felder and Soloman, 1991), the Myers-Briggs Type Indicator (MBTI), and the styles of learning typology (Grasha and Hruska-Riechmann). Results and Discussion: Findings indicated that demonstration and minimal clinical exposure give students personal validation. Frequent feedback on their work is strongly indicated to build the cognitive, psychomotor, and interpersonal skills needed from preclinical oral surgery courses. Conclusion: Small group cooperative active learning in the form of demonstration and minimal clinical exposure that gives frequent feedback and students’ personal validation on their work is strongly indicated to build the skills needed for preclinical oral surgery courses.

    This study aims to compare the efficiency of four oral fluid collection methods (Salivette, FTA Card, spitting and DNA-Sal) to detect HBV DNA by qualitative PCR. Seventy-four individuals (32 HBV reactive and 42 with no HBV markers) donated serum and oral fluid. In-house qualitative PCR to detect HBV was used for both samples and commercial quantitative PCR for serum. HBV DNA was detected in all serum samples from HBV-infected individuals, and it was not detected in control group. HBV DNA from HBV group was detected in 17 samples collected with Salivette device, 16 samples collected by FTA Card device, 16 samples collected from spitting and 13 samples collected by DNA-Sal device. Samples that corresponded to a higher viral load in their paired serum sample could be detected using all oral fluid collection methods, but Salivette collection device yielded the largest numbers of positive samples and had a wide range of viral load that was detected. It was possible to detect HBV DNA using all devices tested, but higher number of positive samples was observed when samples were collected using Salivette device, which shows high concordance to viral load observed in the paired serum samples. © 2017 John Wiley & Sons A/S.

    In the recent years low intensity laser irradiation is made use of in stomatology with the view of treating numerous diseases of the oral cavity mucosa and parodontium. The oral cavity mucosa lesions caused by the internal organs diseases, especially those of blood and the gastroenteric tract, constitute a particular group. Such diseases are usually manifested by an inflammation, erosions, ulcers, hemorrhages. An abundant microflora of the oral cavity and diminished immunity of the patients contribute to the possibility of septicaemia development. Laser therapy of the oral cavity mucosa lesions according to strictly defined indications promotes rapid healing of ulcers, arresting the oral cavity mucosa inflammation, providing a reduction in bleeding and presents a safe prophylactic means of stomatogenic sepsis.

    Full Text Available ABSTRACT Purpose: to analyze auditory and oral communication behaviors in a group of children and adolescents, users of cochlear implants and to establish a relationship with factors that interfere with aural rehabilitation. Methods: participants were 13 children or adolescents with profound bilateral sensorineural hearing loss. Standardized procedures were applied to check: the auditory and oral communication behaviors of participants and their relationships with the child's age at diagnosis period; the interval between diagnosis and intervention, adaptation onset of the cochlear implant; the hearing age and aural rehabilitation period. Results: statistically significant data were found to correlate the interval between diagnosis and intervention with the scores in the evaluation procedures of oral communication. Conclusion: there was a significant impact on the development of oral communication when the period elapsed between the diagnosis and intervention was analyzed, in such way that the faster the intervention time, the better the results. It was also evident that the earlier the beginning of the use of cochlear implants, the greater the hearing age, and the longer the rehabilitation period, the better the scores in the procedures that evaluated auditory and verbal development.

    To evaluate the efficacy and safety of combined treatment of mud-bath therapy and glucosamine crystalline sulfate (GlcN-S) in patients with knee osteoarthritis (OA). This study was a randomised, controlled, crossover investigation. Patients were randomly assigned (1:1) by the investigators to two groups, named group 1 and 2. Group 1 included twenty-three patients receiving oral GlcN-S treatment from the beginning of the study (T0) to the end of the 3rd month of treatment (T3) and a combined treatment of both mud-bath therapy and GlcN-S from T3 to the end of the study at six months (T6). Group 2 included twenty-two patients receiving a combined treatment of both mud-bath therapy and GlcN-S from T0 to T3 and that discontinued mud-bath therapy, receiving GlcN-S treatment alone, from T3 to T6. Primary endpoints of the study consisted of evaluating OA severity and activity at baseline and at follow-up visits. All 45 patients, eligible for the study, completed the period of the crossover. In group 1, no significant difference was shown in the comparison from T0 to T3, while from T3 to T6 most variables were significantly improved. In group 2, instead, the comparison between T0 and T3 showed a significant difference in different parameters. When comparing T3 and T6, despite an improvement of all the variables, no significant difference was shown. The association of GlcN-S and mud-bath therapy has a positive and safe role in improving pain, function and quality of life in knee OA patients.

    The aim of this article is to report weight loss in patients with schizophrenia after switching from olanzapine standard oral tablet (SOT) to olanzapine orally disintegrating tablets (ODT). In the first case report, the patient was switched to olanzapine ODT in daily dosage of 20 mg, while in the second case report, the patient was switched to olanzapine ODT in daily dosage of 15 mg, and weight loss was similar (14 kg vs. 15 kg). Switching patients from olanzapine SOT to olanzapine ODT treatment resulted in significant weight loss that was maintained during 12 months in both case reports. Further controlled clinical investigations are necessary to evaluate change in weight during treatment with olanzapine ODT, and to improve our understanding of this change.

    Post graduate learning and assessment is an important responsibility of an academic oral and maxillofacial surgeon. The current method of assessment for post graduate training include formative evaluation in the form of seminars, case presentations, log books and infrequently conducted end of year theory exams. End of the course theory and practical examination is a summative evaluation which awards the degree to the student based on grades obtained. Oral and maxillofacial surgery is mainly a skill based specialty and deliberate practice enhances skill. But the traditional system of assessment of post graduates emphasizes their performance on the summative exam which fails to evaluate the integral picture of the student throughout the course. Emphasis on competency and holistic growth of the post graduate student during training in recent years has lead to research and evaluation of assessment methods to quantify students' progress during training. Portfolio method of assessment has been proposed as a potentially functional method for post graduate evaluation. It is defined as a collection of papers and other forms of evidence that learning has taken place. It allows the collation and integration of evidence on competence and performance from different sources to gain a comprehensive picture of everyday practice. The benefits of portfolio assessment in health professions education are twofold: it's potential to assess performance and its potential to assess outcomes, such as attitudes and professionalism that are difficult to assess using traditional instruments. This paper is an endeavor for the development of portfolio method of assessment for post graduate student in oral and maxillofacial surgery.

  4. Significant Depletion of CD4+ T Cells Occurs in the Oral Mucosa during Simian Immunodeficiency Virus Infection with the Infected CD4+ T Cell Reservoir Continuing to Persist in the Oral Mucosa during Antiretroviral Therapy

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Human and simian immunodeficiency virus (HIV and SIV infections are characterized by manifestation of numerous opportunistic infections and inflammatory conditions in the oral mucosa. The loss of CD4+ T cells that play a critical role in maintaining mucosal immunity likely contributes to this process. Here we show that CD4+ T cells constitute a minor population of T cells in the oral mucosa and display a predominantly central memory phenotype mirroring other mucosal sites such as the rectal mucosa. Chronic SIV infection was associated with a near total depletion of CD4+ T cells in the oral mucosa that appear to repopulate during antiretroviral therapy (ART. Repopulating CD4+ T cells harbored a large fraction of Th17 cells suggesting that ART potentially reconstitutes oral mucosal immunity. However, a minor fraction of repopulating CD4+ T cells harbored SIV DNA suggesting that the viral reservoir continues to persist in the oral mucosa during ART. Therapeutic approaches aimed at obtaining sustainable CD4+ T cell repopulation in combination with strategies that can eradicate the latent viral reservoir in the oral mucosa are essential for better oral health and long-term outcome in HIV infected patients.

    Background and purpose: Oral mucositis (OM) is most cumbersome acute side effect of concurrent chemoradiotherapy (CCRT) for head and neck cancer (HNC). OM associated pain affects oral functions and nutrition of the patient that may result in discontinuity of treatment. Several modalities have been tried to prevent and treat OM, but none proved completely successful until date. We used prophylactic low level laser therapy (LLLT) for the prevention and treatment of CCRT induced OM. Materials and methods: In this triple blinded study, 221 HNC patients scheduled to undergo CCRT (Cisplatin (1, 22, 43 day) + RT = 66 Grays (2 Gy/fraction), 33 fractions, 5 fractions/week, for 45 days) were block randomized into laser (n = 111) and placebo (n = 110) group. Laser group received LLLT (HeNe, λ = 632.8 nm, power-density = 24 mW, dosage = 3.0 J/point, total dosage/session = 36–40 J, spot-size = 1 cm 2 , 5 sessions/week) while placebo received sham treatment daily prior to radiation. OM (RTOG/EORTC Scale), oral pain (VAS), dysphagia (FIS), weight loss and CCRT break were assessed. Data were analyzed using frequencies and percentage, generalized estimating equations (GEE) and odds ratio. Results: There was significant reduction in incidence of severe OM (F = 16.64, df = 8876, p < 0.0001) and its associated pain (F = 25.06, df = 8876, p < 0.0001), dysphagia (F = 20.17, df = 8876, p < 0.0001) and opioid analgesics use (p < 0.0001) in laser than placebo group patients. Conclusions: LLLT decreased the incidence of CCRT induced severe OM and its associated pain, dysphagia and opioid analgesics use.

  7. Dental plaque as a biofilm - a risk in oral cavity and methods to prevent

    2015-10-01

    Full Text Available Bacteria living constantly in the oral cavity are in the form of a biofilm. The biofilm formed on a solid base such as the enamel of the teeth, fillings, restorations, orthodontic appliances or obturators is dental plaque. Disturbance of homeostasis of biofilm, excessive growth or increase in the number of acid-forming bacteria leads to the development of the most common diseases of the oral cavity, i.e. dental caries and periodontal disease. The presence of bacterial biofilm on the walls of the root canal or at the top of the root on an outer wall leads to complications and failure in endodontic treatment. The aim of the study was to present the latest information on the occurrence, development and the role of biofilm in the etiopathogenesis of oral diseases and its control. Based on the literature analyzed, it can be concluded that the biofilm, due to its complex structure and numerous mechanisms of bacteria adaptation, is an effective barrier against the traditional agents with antibacterial properties. There are now great hopes for nanotechnology as an innovative method for obtaining new structures of nanometric size and different properties than source materials. The use of antibacterial properties of nano-silver used in dentistry significantly reduces the metabolic activity and the number of colony forming bacteria and lactic acid production in the biofilm.

    The time for the neutrophil count to recover after subcutaneous injection of filgrastim BS1 or lenograstim was studied in patients suffering from neutropenia following preoperative combined chemotherapy using docetaxel, nedaplatin, or cisplatin (in divided doses for 5 days)and 5-fluorouracil for oral cancer. 1. There was no significant difference in the minimum leukocyte and neutrophil counts after chemotherapy. 2. There was no significant difference in the maximum leukocyte and neutrophil counts after chemotherapy. 3. Time for leukocytes to recover from their minimum count(>4,000/mm3)or for neutrophils to recover from their minimum count(>2,000/mm3)and the number of days on which treatment was administered tended to be shorter in the filgrastim BS1 group. Thus, it was concluded that filgrastim BS1 is just as effective as other prior G-CSF agents in treating patients suffering from neutropenia following chemotherapy(TPF therapy).

    Background: The present study aimed to evaluate the different methods for removing oral biofilm in combination with 0.12% chlorhexidine, in patients admitted to the intensive care unit (ICU) of the General University Hospital. Materials and Methods: Initially, the patients were included in the study and underwent periodontal evaluation by means of the visible plaque index (VPI) and gingival bleeding index (GBI). The removal of visible biofilm, by a professional, was carried out using a toothbrush and dental floss, followed by the application of a 0.12% chlorhexidine solution. The patients were included in this randomized and controlled study into four groups (total n = 48), as follows: Chlorhexidine and gauze 12/12 h; chlorhexidine and gauze 24/24 h; chlorhexidine and brushing 12/12 h; chlorhexidine and brushing 24/24 h. The patients underwent the biofilm removal protocol for 7 days and then were subjected to a new clinical evaluation as to VPI and GBI. Data analysis was performed through stratification and arrangement of the records, in order to carry out the associations with health indicators used in the study, and the statistical tests used were Kappa and t-test for independent and paired samples. Results: A decrease in the VPI and GBI values when comparing baseline to the final evaluation for all groups was observed. Conclusion: Based on the methodology, it was possible to concluded that chlorhexidine associated with the mechanical action of the toothbrush or gauze in the times 12 h and 24 h in the ICU environment presented the same results as regards amount of visible biofilm.

    To evaluate the efficacy of oral antioxidant supplementation in the treatment of patients with dry eye syndrome (DES). A prospective, randomized, double-blinded study compared the effects of an antioxidant supplement (containing anthocyanosides, astaxanthin, vitamins A, C, and E, and several herbal extracts, including Cassiae semen and Ophiopogonis japonicus) with placebo on patients with DES. We assessed dry eye symptoms, visual acuity, Schirmer's test, tear film breakup time, cornea and conjunctiva fluorescein staining, serum anti-SSA/anti-SSB antibodies, and the level of reactive oxygen species (ROS) in tears. The supplementation period was 8 weeks and patients were followed up every 4 weeks for 16 weeks. A linear mixed model was used to compare the groups, while within-group differences were tested by repeated-measures analysis of variance. Forty-three patients, 20 and 23 in treatment and placebo groups, respectively, completed the study. Liver and renal functions were normal. Diastolic blood pressure decreased in the treatment group. There were no significant differences in systolic blood pressure, dry eye symptoms, serum anti-SSA and anti-SSB, visual acuity, intraocular pressure, or fluorescein corneal staining between the groups. Tear film breakup time scores and Schirmer's test without topical anesthesia significantly improved in the treatment group. Tear ROS level differed between the groups and decreased after treatment. Overall subjective impression revealed a significant improvement with treatment compared with placebo. Oral antioxidant supplementations may increase tear production and improve tear film stability by reducing tear ROS. The vegetable-based antioxidant supplement used in this study is safe and can be utilized as an adjuvant therapy to conventional artificial tear therapy for patients with DES.

    Full Text Available Fosfomycin is a new agent to Canada approved for the treatment of acute uncomplicated cystitis (AUC in adult women infected with susceptible isolates of E. coli and Enterococcus faecalis. We reviewed the literature regarding the use of oral fosfomycin for the treatment of AUC. All English-language references from 1975 to October 2015 were reviewed. In Canada, fosfomycin tromethamine is manufactured as Monurol® and is available as a 3-gram single dose sachet. Fosfomycin has a unique chemical structure, inhibiting peptidoglycan synthesis at an earlier site compared to β-lactams with no cross-resistance with other agents. Fosfomycin displays broad-spectrum activity against ESBL-producing, AmpC-producing, carbapenem-non-susceptible, and multidrug-resistant (MDR E. coli. Resistance to fosfomycin in E. coli is rare (100 µg/mL for 48 hours after a single 3-gram oral dose. No dosage adjustments are required in elderly patients, in pregnant patients, or in either renal or hepatic impairment. Fosfomycin demonstrates a favorable safety profile, and clinical trials have demonstrated efficacy in AUC that is comparable to ciprofloxacin, nitrofurantoin, and trimethoprim-sulfamethoxazole. Fosfomycin’s in vitro activity against common uropathogens, including MDR isolates, its favorable safety profile including pregnancy patients, drug interactions, and clinical trials data demonstrating efficacy in AUC, has resulted in Canadian, US, and European guidelines/authorities recommending fosfomycin as a first line agent for the treatment of AUC.

    Background: Oral mucositis (OM) is a complication of chemoradiotherapy treatment of head and neck squamous cell carcinoma (HNSCC) patients with no effective therapy. This study was designed to assess the efficacy of preventive low-level laser therapy (LLLT) in reducing the incidence of grade 3–4 OM. Material and methods: From June 2007 to December 2010, 94 HNSCC patients entered a prospective, randomized, double-blind, placebo-controlled phase III trial. Chemoradiotherapy consisted of conventional radiotherapy plus concurrent cisplatin every 3 weeks. A diode InGaAlP (660 nm–100 mW–1 J–4 J/cm 2 ) was used. OM evaluation was performed by WHO and OMAS scales and quality of life by EORTC questionnaires (QLQ). Results: A six-fold decrease in the incidence of grades 3–4 OM was detected in the LLLT group compared to the placebo; (6.4% versus 40.5%). LLLT impacted the incidence of grades 3–4 OM to a relative risk ratio of 0.158 (CI 95% 0.050–0.498). After treatment QLQ-C30 showed, differences favoring LLLT in physical, emotional functioning, fatigue, and pain; while the QLQ-H and N35 showed improvements in LLLT arm for pain, swallowing, and trouble with social eating. Conclusion: Preventive LLLT in HNSCC patients receiving chemoradiotherapy is an effective tool for reducing the incidence of grade 3–4 OM. Efficacy data were corroborated by improvements seen in quality of life

    2013-01-01

    The usefulness as one of the tools for self-medication of oral rehydration therapy (ORT), recommended as a safe and effective therapy for mild to moderate dehydration, was surveyed by questionnaire for pharmacists in community pharmacies. ORT products were sold in 112 pharmacies (61%), and the common product was OS-1(®). Approximately 50% of sellers answered that they had no particular difficulty in explaining ORT. Percentage to answer "hard to describe" is significantly higher in pharmacists who believe there is a need to consider underlying health conditions of customers or patients when implementing ORT. Around 77% of pharmacists considered ORT to be useful in patients as a method of self-medication. A significant number of pharmacists selling ORT products depends on the consultation from customers or patients and provide advice to them confirming that ORT was useful. From these results, it was suggested that further information concerning ORT, such as its use in patients with chronic disorders or signs for completion, and the initiative of pharmacists to participate are necessary for spread the efficacy of ORT for self-medication in patients.

    This paper describes mainly development studies on the determination method of in vivo 10 B for the purpose of employment for neutron capture therapy for malignant melanoma and other tumors. To darify the efficacy of the neutron capture therapy, it is necessary to determine 10 B concentration in the diseased part. This study aimed at in vivo 10 B concention determination in living sample to the level of ppm order with 10 % of analytical error within 1 hour, and these determination conditions were satified by prompt γ-ray (478 keV) determination of 10 B (n, αγ) 7 Li reaction. This method required no sample pretreatment. Further, data normalization by γ-ray of H(n, γ)D reaction permitted no disturbance by sample shape or size. Lower limit of detection of the proposed method was estimated in terms of measuring time and statistical error by the equations of 10 B concentration and error analysis derived by the authors. As for the effect of prompt γ-rays of 23 Na(n, γ) 24 Na and 6 Li(n, γ) 7 Li reactions, it was clarified that the former showed no disturbance but some correction was necessary in case of less than 0.1 g of smaple size owing to the latter reaction. In vivo sample determination showed the proposed method was practical. In this paper some results of phantom experiment for in vivo non-destructive 10 B measurement and related simulation calculation, and examination of effect of (γ, n) reaction in heavy water of biomedical irradiation equipment on radiation quality were also described.

    Oral complications of radiation therapy for head and neck cancer (HNC) are associated with a significant decline in oral health-related quality of life (OHQOL). The dentist, working with the radiation oncologist and the rest of the health care team, plays an important role in the prevention and management of these complications, but patients do not always receive care consistent with current guidelines. This study investigated barriers to recommended care. There is variability in knowledge and practice among dentists and radiation oncologists regarding the dental management of patients treated with head and neck radiotherapy (HNRT), and inadequate communication and collaboration between members of the patient's health care team contribute to inconsistencies in application of clinical care guidelines. There is on interest and need for continuing dental (CDE) and medical education (CME) on this topic. A questionnaire was developed to assess dentists' knowledge and practice of dental management of HNC patients and their interest in CDE on this topic. All members of the Michigan Dental Association (MDA) with email addresses were asked to complete the survey online, and a random sample of MDA members without email addresses was invited to complete a paper version of the same survey. All Michigan members of the American Society for Radiation Oncology (ASTRO) were invited to complete an online version of the survey modified for radiation oncologists. The response rate for dentists was 47.9% and radiation oncologists was 22.3%. Of the dentists who responded, 81% reported that a major barrier to providing dental treatment before radiotherapy was a lack of time between initial dental consultation and the start of radiation; inadequate communication between health care providers was blamed most frequently for this. Ten percent of the dentists and 25% of the radiation oncologists reported that they did not treat HNC patients because they lacked adequate training, and 55% of

    Intrauterine adhesion (IUA) is one of the most common gynecological diseases in women of reproductive age. IUA, particularlyin moderate to severe forms, accounts for a large percentage of infertility cases. Clinically, the first-line treatment strategy for IUA is transcervical resection of adhesion (TCRA), followed by adjuvant postoperative treatment. Estrogen is one of the classic chemotherapies used following TCRA and contributes to preventing re-adhesion following surgery. However, estrogen has limited effects in promoting pregnancy, which is the ultimate goal for IUA management. In the present study, a transdermal estrogen gel and oral aspirin combination therapy was used in patients with IUA following TCRA. Compared with in the control group (transdermal estrogen only therapy), the combination therapy significantly increased endometrial receptivity marker (αvβ٣ and laminin) expression in endometrium tissues. Additionally, ultrasonic examination revealed the pulsatility index and resistant index of the uterine artery were lower in the combination therapy group. Combination therapy promoted angiogenesis and prevented fibrosis following TCRA more effectively than estrogen-only therapy. Collectively, the evaluation indices, including American Fertility Society score, endometrial parameters and pregnancy rate, indicated that patients with combination therapy had better prognoses in endometrial repair and pregnancy. In conclusion, postoperative combination therapy with transdermal estrogen gel and oral aspirin may be more efficacious in enhancing endometrial receptivity by increasing uterine blood and angiogenesis, contributing to improved fertility prognosis. The findings of the present study may provide novel guidance to the clinical treatment of IUA. PMID:29512784

    Guidelines recommend limiting the duration of oral antibiotic therapy in acne to 3 to 6 months and prescribing concomitant topical retinoids for all patients. We sought to evaluate the duration of therapy with oral tetracyclines and the use of topical retinoids among patients with acne treated primarily by general practitioners in the United Kingdom. We conducted a retrospective cohort study using the Health Improvement Network database. The mean duration of therapy was 175.1 days. Of antibiotic courses, 62% were not associated with a topical retinoid; 29% exceeded 6 months in duration. If all regions were to achieve uses similar to the region with the shortest mean duration of therapy, approximately 3.3 million antibiotic days per year could be avoided in the United Kingdom. The Health Improvement Network does not include information on acne severity and clinical outcomes. Prescribing behavior for oral antibiotics in the treatment of acne among general practitioners is not aligned with current guideline recommendations. Increasing the use of topical retinoids and considering alternative agents to oral antibiotics when appropriate represent opportunities to reduce antibiotic exposure and associated complications such as antibiotic resistance and to improve outcomes in patients treated for acne.

    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.

    The definition of non-valvular atrial fibrillation (NVAF) is controversial. We aimed to assess the impact of valvular heart disease on stroke prevention strategies in NVAF patients. The RAMSES study was a multicenter and cross-sectional study conducted on NVAF patients (ClinicalTrials.gov identifier NCT02344901). The study population was divided into patients with significant valvular disease (SVD) and non-significant valvular disease (NSVD), whether they had at least one moderate valvular disease or not. Patients with a mechanical prosthetic valve and mitral stenosis were excluded. Baseline characteristics and oral anticoagulant (OAC) therapies were compared. In 5987 patients with NVAF, there were 3929 (66%) NSVD and 2058 (34%) SVD patients. The predominant valvular disease was mitral regurgitation (58.1%), followed by aortic regurgitation (24.1%) and aortic stenosis (17.8%). Patients with SVD had higher CHA 2 DS 2 VASc [3.0 (2.0; 4.0) vs. 4.0 (2.0; 5.0), p valvular heart disease with the predominance of mitral regurgitation. Patients with SVD were at greater risk of stroke and bleeding compared to patients with NSVD. Although patients with mitral regurgitation should be given more aggressive anticoagulant therapy due to their higher risk of stroke, they are undertreated compared to patients with aortic valve diseases.

    A growing number of premenopausal women are currently using antithrombotic and/or (dual) antiplatelet therapy for various cardiovascular indications. These may induce or exacerbate abnormal uterine bleeding and more awareness and knowledge among prescribers is required. Heavy and irregular menstrual bleeding is common in women in their forties and may have a variety of underlying causes that require different treatment options. Thus using anticoagulants in premenopausal women demands specific expertise and close collaboration between cardiovascular physicians and gynecologists. In this article we summarize the scope of the problem and provide practical recommendations for the care for young women taking anticoagulants and/or (dual) antiplatelet therapy. We also recommend that more safety data on uterine bleeding with novel anticoagulants in premenopausal women should be obtained. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    BACKGROUND Psoriasis is known as the most frequent disease treated by long-term topical steroids. It is also known that patients with thick, chronic plaques require the highest potency topical steroids. However, the treatment is limited to up to four weeks due to risk of systemic absorption. CASE REPORT An 80-year-old man was diagnosed with type 2 diabetes 16 years before, and was being administered insulin combined with alpha glucosidase inhibitor. He was diagnosed with plaque psoriasis and his oral steroid treatment was switched to topical steroid treatment due to lack of improvement and poorly controlled blood glucose level. The hypoglycemic events improved after the psoriatic lesions improved. CONCLUSIONS Control of blood glucose level is difficult at the very beginning of topical steroid treatment for psoriasis especially if a patient is receiving insulin treatment. Intense monitoring of blood glucose level during initiation of topical steroid treatment is necessary to prevent unfavorable complications.

Three different monomers containing various zwitterionic groups, i.e., phosphorylcholine (PC), sulfobetaine (SB), and carboxybetaine (CB), were copolymerized with the methacrylic monomer containing a Ca2+-binding moiety, using the free radical polymerization method. As a control, functionalization of the copolymer containing the Ca2+-binding moiety was synthesized using a hydroxy group. The stable immobilization of the zwitterionic functional groups was confirmed by water contact angle analysis and X-ray photoelectron spectroscopy (XPS) measurement conducted after the sonication process. The zwitterionized HA surface showed significantly decreased protein adsorption, whereas the hydroxyl group-coated HA surface showed limited efficacy. The anti-bacterial adhesion property was confirmed by conducting Streptococcus mutans (S. mutans) adhesion tests for 6 h and 24 h. When furanone C-30, a representative anti-quorum sensing molecule for S. mutans, was used, only a small amount of bacteria adhered after 6 h and the population did not increase after 24 h. In contrast, zwitterionized HA surfaces showed almost no bacterial adhesion after 6 h and the effect was retained for 24 h, resulting in the lowest level of oral bacterial adhesion. These results confirm that surface zwitterionization is a promising method to effectively prevent oral bacterial adhesion on HA-based materials.

Equilibrium solubility and intrinsic dissolution rate (IDR of NCE were estimated in different phosphate buffers. Effective intestinal permeability (Peff of NCE was determined using single-pass intestinal perfusion technique in rat duodenum, jejunum and ileum at three concentrations. Theophylline (high permeability and ranitidine (low permeability were also applied to access the permeability of NCE as reference compounds. The bioavailability after intragastrical and intravenous administration was measured in beagle dogs. The solubility of NCE in tested phosphate buffers was quite low with the maximum solubility of 81.73 μg/mL at pH 1.0. The intrinsic dissolution ratio of NCE was 1 × 10−4 mg·min−1·cm−2. The Peff value of NCE in all intestinal segments was more proximate to the high-permeability reference theophylline. Therefore, NCE was classified as class II drug according to Biopharmaceutics Classification System due to its low solubility and high intestinal permeability. In addition, concentration-dependent permeability was not observed in all the segments, indicating that there might be passive transportation for NCE. The absolute oral bioavailability of NCE in beagle dogs was 26.75%. Therefore, dissolution promotion will be crucial for oral formulation development and intravenous administration route will also be suggested for further NCE formulation development. All the data would provide a reference for biopharmaceutics classification research of other novel drug candidates.

    Full Text Available Objectives: Oral Squamous Cell Carcinoma (OSCC is the most frequent oral cancer worldwide. It is known as the eighth most common cancer in men and as the fifth most common cancer in women. Cytogenetic and biochemical studies in recent decades have emphasized the necessity of providing an appropriate tool for such researches. Cancer cell culture is a useful tool for investigations on biochemical, genetic, molecular and immunological characteristics of different cancers, including oral cancer. Here, we explain the establishment process of five primary oral cancer cells derived from an Iranian population.Materials and Methods: The specimens were obtained from five oral cancer patients. Enzymatic, explant culture and magnetic-activated cell sorting (MACS methods were used for cell isolation. After quality control tests, characterization and authentication of primary oral cancer cells were performed by short tandem repeats (STR profiling, chromosome analysis, species identification, and monitoring the growth, morphology and the expression of CD326 and CD133 markers.Results: Five primary oral cancer cells were established from an Iranian population. The flow cytometry results showed that the isolated cells were positive for CD326 and CD133 markers. Furthermore, the cells were free from mycoplasma, bacterial and fungal contamination. No misidentified or cross-contaminated cells were detected by STR analysis.Conclusions: Human primary oral cancer cells provide an extremely useful platform for studying carcinogenesis pathways of oral cancer in Iranian population. They may be helpful in explaining the ethnic differences in cancer biology and the individuality in anticancer drug response in future studies.

    Previous studies of glucocorticoid (GC) therapy and mortality have had inconsistent results and have not considered possible perimortal bias—a type of protopathic bias where illness in the latter stages of life influences GC exposure, and might affect the observed relationship between GC use and death. This study aimed to investigate all-cause and cause-specific mortality in association with GC therapy in patients with rheumatoid arthritis (RA), and explore possible perimortal bias. A retrospective cohort study using the primary care electronic medical records. Oral GC exposure was identified from prescriptions. Mortality data were obtained from the UK Office for National Statistics. Multivariable Cox proportional hazards regression models assessed the association between GC use models and death. Several methods to explore perimortal bias were examined. The cohort included 16,762 patients. For ever GC use there was an adjusted hazard ratio for all-cause mortality of 1.97 (95 % CI 1.81–2.15). Current GC dose of below 5 mg per day (prednisolone equivalent dose) was not associated with an increased risk of death, but a dose–response association was seen for higher dose categories. The association between ever GC use and all-cause mortality was partly explained by perimortal bias. GC therapy was associated with an increased risk of mortality for all specific causes considered, albeit to a lesser extent for cardiovascular causes. GC use was associated with an increased risk of death in RA, at least partially explained by perimortal bias. Importantly, GC doses below 5 mg were not associated with an increased risk of death.

    Full Text Available Background:The disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp.to chemicals:janus green, ethidium bromide,2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6G. Methods: Atotal of 568 Iranian soldiers went under study for isolation and identification of Yeast species from their oral cavity. Asterile swab was used for each individual and specimens were collected from the nasopharynx region, then inoculated to petri dishes containing Sabouraud Dextrose Agar and incubated for 48 hrs at 37 °C. All colonies were counted and stocked in distilled water and stored in a refrigerator for further analysis. The yeasts were identified by the “disk diffusion test” [6,8]. This is a simple, rapid, accurate, and inexpensive technique presented by Sobczak [8]. By this method we identified yeast species within 24-48 hrs. Results: 51.4% of petri dishes were positive for yeast species and 318 strains were identified. Candida albicans, Candida kefyr, Candida tropicalis and Candida guilliermondii were the most common yeast species isolated from the oral cavity of soldiers. Conclusion: We used this method because of its simplicity and other beneficial characteristics for rapid identification of large and numerous isolates and the results were compared with other morphological characters such as chlamydospore and germ tube production. In addition,we used some type strains (Candida parapsilosis: PTCC 5089,Candida tropicalis: PTCC 5028,Saccharomyces cerevisiae:PTCC 5052,Candida lipolytica: PTCC 5063,Candida lipolytica:PTCC 5064,and the results were acceptable.

  6. A standardized method for beam design in neutron capture therapy

    A desirable end point for a given beam design for Neutron Capture Therapy (NCT) should be quantitative description of tumour control probability and normal tissue damage. Achieving this goal will ultimately rely on data from NCT human clinical trials. Traditional descriptions of beam designs have used a variety of assessment methods to quantify proposed or installed beam designs. These methods include measurement and calculation of open-quotes free fieldclose quotes parameters, such as neutron and gamma flux intensities and energy spectra, and figures-of-merit in tissue equivalent phantoms. The authors propose here a standardized method for beam design in NCT. This method would allow all proposed and existing NCT beam facilities to be compared equally. The traditional approach to determining a quantitative description of tumour control probability and normal tissue damage in NCT research may be described by the following path: Beam design → dosimetry → macroscopic effects → microscopic effects. Methods exist that allow neutron and gamma fluxes and energy dependence to be calculated and measured to good accuracy. By using this information and intermediate dosimetric quantities such as kerma factors for neutrons and gammas, macroscopic effect (absorbed dose) in geometries of tissue or tissue-equivalent materials can be calculated. After this stage, for NCT the data begins to become more sparse and in some areas ambiguous. Uncertainties in the Relative Biological Effectiveness (RBE) of some NCT dose components means that beam designs based on assumptions considered valid a few years ago may have to be reassessed. A standard method is therefore useful for comparing different NCT facilities

    Optoelectronics techniques to induce protoporphyrin IX fluorescence with topically applied 5-aminolevulinic acid on the oral mucosa have been developed to noninvasively detect oral cancer. Fluorescence imaging enables wide-area screening for oral premalignancy, but the lack of an adequate fluorescence enhancement method restricts the clinical imaging application of these techniques. This study aimed to develop a reliable fluorescence enhancement method to improve PpIX fluorescence imaging systems for oral cancer detection. Three contrast features, red-green-blue reflectance difference, R/B ratio, and R/G ratio, were developed first based on the optical properties of the fluorescence images. A comparative study was then carried out with one negative control and four biopsy confirmed clinical cases to validate the optimal image processing method for the detection of the distribution of malignancy. The results showed the superiority of the R/G ratio in terms of yielding a better contrast between normal and neoplastic tissue, and this method was less prone to errors in detection. Quantitative comparison with the clinical diagnoses in the four neoplastic cases showed that the regions of premalignancy obtained using the proposed method accorded with the expert's determination, suggesting the potential clinical application of this method for the detection of oral cancer.

    The blood circulation of incisors, dental pulp and tongue was detemined using the measurement of 86 Rb distribution in rats. The results were compared with those obtained by a simultaneous micropearl method. It was found that 37 per cent of 86 Rb in dental tissues is localized in the hard propiodentium, with a high proportion diffusing from the periodontium. The 86 Rb fraction localized in the tongue represents its blood circulation. (author)

  9. The viability of alternative assessment methods in the Greek upper secondary school: the oral portfolio

    Full Text Available Τhe final examination of the English language subject, in the context of the Greek state upper secondary education, is a traditional paper-and-pencil test which does not include any assessment of oracy skills. This article explores the viability of the oral portfolio as an alternative assessment and pedagogic method that can facilitate the assessment of speaking and listening skills and create a more motivating learning environment. To this effect, three methodological tools were designed, namely, a questionnaire addressing upper secondary English teachers in Greek state schools, a case study involving an oral portfolio implementation and finally, a questionnaire for students to record their experience. The study demonstrates that implementation of the portfolio contributed to a successful assessment of oracy skills and that it was a stimulating experience for students. The results of the study also showed that the pedagogical value of the portfolio counterbalanced its practical constraints. The paper concludes by putting forward recommendations for the future application of this assessment technique in state school education.

    Newborn infants with risk factors may require intravenous (IV) dextrose for asymptomatic hypoglycemia. Administration of IV dextrose and transfer to the neonatal intensive care unit (NICU) may interfere with parent-infant bonding. To study the effect of implementing dextrose gel supplement with feeds in late preterm/term infants affected by asymptomatic hypoglycemia on reducing IV dextrose therapy. A retrospective study was conducted before and after dextrose gel use: 05/01/2014 to 10/31/2014 and 11/01/2014 to 04/30/2015, respectively. Asymptomatic hypoglycemic (blood glucose level dextrose gel (200 mg/kg of 40% dextrose) along with feeds. Transfer to the NICU for IV dextrose was considered treatment failure. Dextrose gel with feeds increased the blood glucose level in 184/250 (74%) of asymptomatic hypoglycemic infants compared to 144/248 (58%) with feeds only (p dextrose decreased from 35/1,000 to 25/1,000 live births (p dextrose gel with feeds reduced the need for IV fluids, avoided separation from the mother and promoted breastfeeding. Neonates who failed dextrose gel therapy were more likely to be large for gestational age, delivered by cesarean section and had lower baseline blood glucose levels.

    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.

    Background and Objective : Contraceptive pills are generally taken orally and can cause side effects such as nausea, vomiting and hypertension. The vaginal use of these pills can reduce such complications. Our objective was to compare the efficacy and side effects of low dose contraceptive pills by oral and vaginal route in the management of dysfunctional uterine bleeding-(DUB) Methods: This comparative observational study was conducted at Beheshti and Alzahra (SA) teaching hospitals, affiliated to Isfahan University of Medical Sciences in 2010-2011. One hundred women who presented with DUB were randomly assigned into two groups of equal number, receiving the low dose oral contraceptive pills by oral or vaginal route for three month. The amount and duration of bleeding were compared at the beginning and at the end of the study and side effects by these two methods compared. The results of this study showed that both oral and vaginal routes effectively reduced the duration and amount of bleeding due to DUB after three courses of treatment. This effect was better in the vaginal method compared with oral administration (P = 0.03). Regarding the side effects, nausea and vomiting were significantly higher in the oral group than in the vaginal group (P = 0.03). Vulvovaginitis infection was more frequent in the vaginal group than in the oral group (P = 0.03). Low dose contraceptive pills are effective in reducing the amount, time, and duration of bleeding in patients with DUB. In addition, reduction of gastrointestinal side effects by vaginal route helps to use these pills by the patient with proper training of physicians, midwives and patients.

  13. Impact of high-flux haemodialysis on the probability of target attainment for oral amoxicillin/clavulanic acid combination therapy.

    Clearance of small molecules such as amoxicillin and clavulanic acid is expected to increase during high-flux haemodialysis, which may result in lower concentrations and thus reduced efficacy. To date, clearance of amoxicillin/clavulanic acid (AMC) during high-flux haemodialysis remains largely unexplored. Using published pharmacokinetic parameters, a two-compartment model with first-order input was simulated to investigate the impact of high-flux haemodialysis on the probability of target attainment (PTA) of orally administered AMC combination therapy. The following pharmacokinetic/pharmacodynamic targets were used to calculate the PTA. For amoxicillin, the time that the free concentration remains above the minimum inhibitory concentration (MIC) of ≥50% of the dosing period (≥50%ƒT >MIC ) was used. For clavulanic acid, the time that the free concentration was >0.1 mg/L of ≥45% of the dosing period (≥45%ƒT >0.1 mg/L ) was used. Dialysis clearance reported in low-flux haemodialysis for both compounds was doubled to represent the likely clearance during high-flux haemodialysis. Monte Carlo simulations were performed to produce concentration-time profiles over 10 days in 1000 virtual patients. Seven different regimens commonly seen in clinical practice were explored. When AMC was dosed twice daily, the PTA was mostly ≥90% for both compounds regardless of when haemodialysis commenced. When administered once daily, the PTA was 20-30% for clavulanic acid and ≥90% for amoxicillin. The simulations suggest that once-daily orally administered AMC in patients receiving high-flux haemodialysis may result in insufficient concentrations of clavulanic acid to effectively treat infections, especially on days when haemodialysis occurs.

    Full Text Available Oral anticoagulation therapy is increasingly used for the prevention and treatment of thromboembolic complications in various clinical situations. Nowadays, education programs for patients treated with anticoagulants constitute an integrated component of their management. However, such programs are usually based on the healthcare providers' perceptions of what patients should know, rather than on patients' preferences.To investigate patients' viewpoints on educational needs and preferred modalities of information delivery.We conducted an observational study based on a self-administered questionnaire. To explore several profiles of patients, the study was designed for enrolling patients in two settings: during outpatient consultations in a cardiology department (Saint Antoine Hospital, Paris, France and in community pharmacies throughout France.Of the 371 patients who completed the questionnaire, 187 (50.4% were recruited during an outpatient consultation and 184 (49.6% were recruited in community pharmacies. 84.1% of patients were receiving a vitamin K antagonist and 15.6% a direct oral anticoagulant. Patients ranked 16 of 21 (76.2% questionnaire items on information about their treatment as important or essential; information on adverse effects of treatment was the highest ranked domain (mean score 2.38, 95% CI 2.30-2.46. Pharmacists (1.69, 1.58-1.80, nurses (1.05, 0.95-1.16, and patient associations (0.36, 0.29-0.44, along with group sessions (0.85, 0.75-0.95, the internet (0.77, 0.67-0.88, and delivery of material at the patient's home (1.26, 1.14-1.38, were ranked poorly in terms of delivering educational material.This study revealed substantial discrepancies between patient preferences and current educational programs. These findings should be useful for tailoring future educational programs that are better adapted to patients, with a potential associated enhancement of their effectiveness.

    Full Text Available Lassa and Junín viruses are the most prominent members of the Arenaviridae family of viruses that cause viral hemorrhagic fever syndromes Lassa fever and Argentine hemorrhagic fever, respectively. At present, ribavirin is the only antiviral drug indicated for use in treatment of these diseases, but because of its limited efficacy in advanced cases of disease and its toxicity, safer and more effective antivirals are needed.Here, we used a model of acute arenaviral infection in outbred guinea pigs based on challenge with an adapted strain of Pichindé virus (PICV to further preclinical development of T-705 (Favipiravir, a promising broad-spectrum inhibitor of RNA virus infections. The guinea pig-adapted passage 19 PICV was uniformly lethal with an LD(50 of ∼5 plaque-forming units and disease was associated with fever, weight loss, thrombocytopenia, coagulation defects, increases in serum aspartate aminotransferase (AST concentrations, and pantropic viral infection. Favipiravir (300 mg/kg/day, twice daily orally for 14 days was highly effective, as all animals recovered fully from PICV-induced disease even when therapy was initiated one week after virus challenge when animals were already significantly ill with marked fevers and thrombocytopenia. Antiviral activity and reduced disease severity was evidenced by dramatic reductions in peak serum virus titers and AST concentrations in favipiravir-treated animals. Moreover, a sharp decrease in body temperature was observed shortly after the start of treatment. Oral ribavirin was also evaluated, and although effective, the slower rate of recovery may be a sign of the drug's known toxicity.Our findings support further development of favipiravir for the treatment of severe arenaviral infections. The optimization of the experimental favipiravir treatment regimen in the PICV guinea pig model will inform critical future studies in the same species based on challenge with highly pathogenic arenaviruses

    Oral mucositis (MO) is considered to be the most severe stomatologic complication associated with antineoplastic treatment, which may lead to its interruption. Several current clinical protocols have aproven the benefits of Laser Photobiomodulation (LP) in the prevention and control of MO, due to its analgesic and anti-inflammatory effects and its stimulation of mesenchymal cells proliferation. The objective of this study was to evaluate the action of laser in initial events of chemo-induced MO. Eight Hamsters were divided into 2 groups (G): GI positive control (induction of MO) and GII Laser (induction of MO + Laser therapy). MO was induced by two injections of 5-Fluorouracil followed by grooves in the mucosa of the cheek pouch. The PL (Diode Laser of Gallium and Aluminum Arsenide, λ660nm, 40mW, 2,4J/cm2 ) was performed on day 0 of the experiment and every 48 hours until day 6. On day 7 the mucosa was photographed for clinical analysis according to Lima et al., 2005 and the animals were killed, for bag removal and histological processing for Hematoxylin and Eosin (H / E) staining. After statistical analysis (Fischer's Exact) with a significance level 0.5%, it was concluded that the LP, according to the adopted protocol, was able to prevent MO, and most hamsters showed no visible clinical changes in the cheek pouch. Histologically, it was observed that LP reduced angiogenesis and recruitment of inflammatory cells in G2. According to the results obtained LP was effective in preventing and reducing the severity of oral mucositis.

    Coagulation factor replacement therapy for the X-linked bleeding disorder hemophilia is severely complicated by antibody ("inhibitor") formation. We previously found that oral delivery to hemophilic mice of cholera toxin B subunit-coagulation factor fusion proteins expressed in chloroplasts of transgenic plants suppressed inhibitor formation directed against factors VIII and IX and anaphylaxis against factor IX (FIX). This observation and the relatively high concentration of antigen in the chloroplasts prompted us to evaluate the underlying tolerance mechanisms. The combination of oral delivery of bioencapsulated FIX and intravenous replacement therapy induced a complex, interleukin-10 (IL-10)-dependent, antigen-specific systemic immune suppression of pathogenic antibody formation (immunoglobulin [Ig] 1/inhibitors, IgE) in hemophilia B mice. Tolerance induction was also successful in preimmune mice but required prolonged oral delivery once replacement therapy was resumed. Orally delivered antigen, initially targeted to epithelial cells, was taken up by dendritic cells throughout the small intestine and additionally by F4/80(+) cells in the duodenum. Consistent with the immunomodulatory responses, frequencies of tolerogenic CD103(+) and plasmacytoid dendritic cells were increased. Ultimately, latency-associated peptide expressing CD4(+) regulatory T cells (CD4(+)CD25(-)LAP(+) cells with upregulated IL-10 and transforming growth factor-β (TGF-β) expression) as well as conventional CD4(+)CD25(+) regulatory T cells systemically suppressed anti-FIX responses. © 2015 by The American Society of Hematology.

    We aimed to investigate the association of difference between observed and predicted glycated hemoglobin (dopHbA1c) and HbA1c reduction after vildagliptin-based oral therapy in patients with type 2 diabetes (T2D). This was a prospective observational study. Adults ≥ 20 years old with T2D and HbA1c ≧7% treated with oral anti-diabetic drugs (OADs) were eligible if their OADs were shifted to vildagliptin-based dual oral therapy. Fasting plasma glucose (FPG) and HbA1c were recorded at baseline, week 12, and week 24. To determine baseline dopHbA1c, a predicted HbA1c was calculated by inserting baseline FPG into a regression equation (HbA1c = FPG ∗ 0.0225 + 4.3806) developed from linear relationship between HbA1c and FPG in an independent cohort of 3239 outpatients with T2D (dopHbA1c = observed HbA1c - predicted HbA1c). Patients were assigned to low (≦0) or high (>0) dopHbA1c group according to their baseline dopHbA1c levels. The study endpoint was changes from baseline to week 24 in HbA1c levels. A total of 1224 patients were enrolled. Patients with a dopHbA1c >0 had a greater HbA1c reduction after vildagliptin-based dual oral therapy than those with a dopHbA1c ≦0 (-1.5 ± 2.0 vs. -0.4 ± 1.0%, p vildagliptin-based dual oral therapy.

    To compare the changes induced by oral versus transdermal estrogen therapy on the total and free serum concentrations of testosterone (T), thyroxine (T4), and cortisol (C) and the concentrations of their serum binding globulins sex hormone-binding globulin, thyroxine-binding globulin, and cortisol-binding globulin in naturally menopausal women. Randomized, open-label, crossover. Interventions included a 6-week withdrawal from previous hormone therapy (baseline), followed in randomized order by 12 weeks of oral conjugated equine estrogens (CEE) (0.625 mg/d) and 12 weeks of transdermal estradiol (TD E2) (0.05 mg/d), with oral micronized progesterone (100 mg/d) given continuously during both transdermal estrogen therapy regimens. Twenty-seven women were enrolled in the study, and 25 completed both treatment periods. The mean(SD) percentage changes from baseline of sex hormone-binding globulin, total T, and free T with oral CEE were +132.1% (74.5%), +16.4% (43.8%), and -32.7% (25.9%), respectively, versus +12.0% (25.1%), +1.2% (43.7%), and +1.0% (45.0%) with TD E2. The mean (SD) percentage changes of thyroxine-binding globulin, total T4, and free T4 with oral CEE were +39.9% (20.1%), +28.4% (29.2%), and -10.4% (22.3%), respectively, versus +0.4% (11.1%), -0.7% (16.5%), and +0.2% (26.6%) with TD E2. The mean (SD) percentage changes of cortisol-binding globulin, total C, and free C with oral CEE were +18.0% (19.5%), +29.2% (46.3%), and +50.4% (126.5%), respectively, versus -2.2% (11.3%), -6.7% (30.8%), and +1.8% (77.1%) with TD E2. Concentrations of all hormones and binding globulins were significantly different (P < or = 0.003) during administration of oral versus transdermal estrogen therapy, except for free T4 and free C. Compared with oral CEE, TD E2 exerts minimal effects on the total and free concentrations of T, T4, and C and their binding proteins.

    Full Text Available Development of new tuberculosis (TB drugs and alternative treatment strategies are urgently required to control the global spread of TB. Previous results have shown that vitamin D3 (vitD3 and 4-phenyl butyrate (PBA are potent inducers of the host defense peptide LL-37 that possess anti-mycobacterial effects.To examine if oral adjunctive therapy with 5,000IU vitD3 or 2x500 mg PBA or PBA+vitD3 to standard chemotherapy would lead to enhanced recovery in sputum smear-positive pulmonary TB patients.Adult TB patients (n = 288 were enrolled in a randomized, double-blind, placebo-controlled trial conducted in Bangladesh. Primary endpoints included proportions of patients with a negative sputum culture at week 4 and reduction in clinical symptoms at week 8. Clinical assessments and sputum smear microscopy were performed weekly up to week 4, fortnightly up to week 12 and at week 24; TB culture was performed at week 0, 4 and 8; concentrations of LL-37 in cells, 25-hydroxyvitamin D3 (25(OHD3 in plasma and ex vivo bactericidal function of monocyte-derived macrophages (MDM were determined at week 0, 4, 8, 12 and additionally at week 24 for plasma 25(OHD3.At week 4, 71% (46/65 of the patients in the PBA+vitD3-group (p = 0.001 and 61.3% (38/62 in the vitD3-group (p = 0.032 were culture negative compared to 42.2% (27/64 in the placebo-group. The odds of sputum culture being negative at week 4 was 3.42 times higher in the PBA+vitD3-group (p = 0.001 and 2.2 times higher in vitD3-group (p = 0.032 compared to placebo. The concentration of LL-37 in MDM was significantly higher in the PBA-group compared to placebo at week 12 (p = 0.034. Decline in intracellular Mtb growth in MDM was earlier in the PBA-group compared to placebo (log rank 11.38, p = 0.01.Adjunct therapy with PBA+vitD3 or vitD3 or PBA to standard short-course therapy demonstrated beneficial effects towards clinical recovery and holds potential for host-directed-therapy in the treatment of TB

    Full Text Available Type 2 diabetes is believed to develop as a result of lowered insulin secretion and insulin resistance leading to hyperglycemia. Sulfonylureas stimulateinsulin secretion and thereby decrease blood glucose level which accounts for their wide application in the treatment of diabetes. However, manyagents of this class produce side effects (increased body mass, hypoglycemia, resistance to therapy, etc. attributable to excess stimulation of insulinsecretion. Glimepiride is as efficient as traditionally used sulfonylureas but causes a smaller rise in insulin secretion. Sulfonylurea receptors showlower affinity for glimepiride than for glibenclamide. Formation and dissociation of glimepiride-receptor complexes occur faster than those of glibenclamide-receptor complexes. In addition, therapeutic effect of glimepiride was shown to be associated with improved insulin sensitivity. It is concludedthat glimepiride is an efficacious agent for the treatment of type 2 diabetes.

    Full Text Available Plasmablastic lymphoma (PBL represents a rare type of non-Hodgkin lymphoma associated with human immunodeficiency virus (HIV infection. The impact of highly active antiretroviral therapy (HAART in this tumor is poorly known due to its small incidence. This study reports a case of a 33-year-old HIV-positive woman who was referred to the Stomatology Department complaining about a painful gingival growth and cervical nodule both with 20 days of evolution. The lesions appeared 7 months after the patient stopped HAART. The final diagnosis was PBL. After resuming HAART for 45 days, the gingival lesion presented complete remission. The patient continued with HAART alongside chemotherapy. At 24 months follow-up, the patient was stable. The dental surgeon plays an essential role in orientation and retention in care of HIV patients once the adherence of HAART seems to play an important role in PBL development and response to treatment.

    Oral histology and pathology is one of the most important courses in stomatological education which works as a bridge between basic medical courses and clinical courses of oral science. The knowledge of oral histopathology may help the students to correctly understand the histogenesis and development of oral diseases and provide the information for correct treatment and prevention. In order to make the students grasp the necessary basic theories, increase the interest in learning, and improve the teaching effect, we explored a diversified teaching system which included diverse teaching modes, online courses and courseware construction. The application of this system offered the interaction between students and teachers and combination of classes with the internet, and made the boring pathological knowledge be associated with clinical practice. These diversified teaching methods had been used in practice and obtained good teaching results.

    Chemotherapy associated or not with radiotherapy and surgery may be used for treating patients presenting some pathogenies such as cancer. Many side effects are visibly in the mouth in several forms as a consequence of this treatment and oral mucositis is the most common, with great prevalence, causing degrees of morbidity and even death. This research is about improving the quality of life for these patients by using of laser radiation through a GaAlAs active medium, in a continuous manner, with a low power ( 60 mW), the diode laser acting at 780 nm wavelength infrared, with a energy density 7,5 J/cm 2 and 6,0 J/cm 2 , for the therapeutic and preventive groups respectively, and a third control group without radiation. Two protocols were studied in patients during 5-fluorouracil chemotherapic regime and combinations, because nowadays polychemotherapy is used, an associations of drugs, for a neoadjuvant treatment, adjuvant, potentionalize or palliative means, for the chemotherapy treatment. In a context of 60 patients, 16 patients had received the laser irradiations doses, 10 days for the therapeutic protocols and 11 days for the preventive irradiations. The therapeutic group presented a 50% of the total healing process and significant decrease in symptoms of pain (VAS=0 with p =0,01). For the preventive irradiations (D-5, D, D+5), that means the day of the QT, 5 days before the chemotherapy regime starts until 5 days later, only 1 patient had some kind of ulceration during more than four months of control. Results of the present study showed to be effective and promising for both employed protocols, therapeutic and preventive. Further studies must be developed in order to improve the present results.

  6. Electrophysiological Studies into the Safety of the Anti-diarrheal Drug Clotrimazole during Oral Rehydration Therapy.

    2015-09-01

    Full Text Available Morbidity and mortality from acute diarrheal disease remains high, particularly in developing countries and in cases of natural or man-made disasters. Previous work has shown that the small molecule clotrimazole inhibits intestinal Cl- secretion by blocking both cyclic nucleotide- and Ca(2+-gated K(+ channels, implicating its use in the treatment of diarrhea of diverse etiologies. Clotrimazole, however, might also inhibit transporters that mediate the inwardly directed electrochemical potential for Na(+-dependent solute absorption, which would undermine its clinical application. Here we test this possibility by examining the effects of clotrimazole on Na(+-coupled glucose uptake.Short-circuit currents (Isc following administration of glucose and secretagogues were studied in clotrimazole-treated jejunal sections of mouse intestine mounted in Ussing chambers.Treatment of small intestinal tissue with clotrimazole inhibited the Cl- secretory currents that resulted from challenge with the cAMP-agonist vasoactive intestinal peptide (VIP or Ca(2+-agonist carbachol in a dose-dependent fashion. A dose of 30 μM was effective in significantly reducing the Isc response to VIP and carbachol by 50% and 72%, respectively. At this dose, uptake of glucose was only marginally affected (decreased by 14%, p = 0.37. There was no measurable effect on SGLT1-mediated sugar transport, as uptake of SGLT1-restricted 3-O-methyl glucose was equivalent between clotrimazole-treated and untreated tissue (98% vs. 100%, p = 0.90.Treatment of intestinal tissue with clotrimazole significantly reduced secretory responses caused by both cAMP- and Ca(2+-dependent agonists as expected, but did not affect Na(+-coupled glucose absorption. Clotrimazole could thus be used in conjunction with oral rehydration solution as a low-cost, auxiliary treatment of acute secretory diarrheas.

    It is not possible with current hydrocortisone replacement to mimic the diurnal cortisol profile in patients with adrenal insufficiency. Previous attempts with modified-release technology were unsuccessful. Our objective was to develop hydrocortisone formulations that recreate the diurnal cortisol profile using multiparticulate technology. Screening by in vitro dissolution profiles, pharmacokinetic (PK) testing in dexamethasone-suppressed dogs and humans, and comparison with a reference population. Field laboratories and clinical research facility. Formulations were generated using an enteric (delayed release) design configuration with an extended (sustained release) dissolution profile. In vitro dissolution confirmed delayed and sustained hydrocortisone release. However, in dogs and humans, sustained release resulted in reduced bioavailability. A formulation, DIURF-006, was developed that maintained delayed release but omitted the sustained-release functionality. PK characterization of DIURF-006 showed that, despite absence of a sustained-release component, absorption was sufficiently sustained to deliver extended hydrocortisone absorption. In dexamethasone-suppressed volunteers (n = 16) receiving a twice-daily 'toothbrush' regimen (20 mg at 23:00 h and 10 mg at 07:00 h), DIURF-006 gave a similar cortisol profile to physiological cortisol levels: DIURF-006 vs physiological, Geomean AUC 5610 vs 4706 h * nmol/l, Geomean Cmax 665 vs 594 nmol/l and Median Tmax 8·5 h vs clock time 08:12 h for peak cortisol. The relative bioavailability of DIURF-006 vs hydrocortisone was 89%, and cortisol levels increased linearly with doses between 5 and 30 mg. A multiparticulate oral hydrocortisone formulation with only an enteric coat provides delayed and sustained absorption and when given in a 'toothbrush' regimen provides physiological cortisol exposure. © 2013 John Wiley & Sons Ltd.

    Multisystemic Therapy (MST) and Functional Family Therapy (FFT) have overlapping target populations and treatment goals. In this study, these interventions were compared on their effectiveness using a quasi-experimental design. Between October, 2009 and June, 2014, outcome data were collected from 697 adolescents (mean age 15.3 (SD 1.48), 61.9% male) assigned to either MST or FFT (422 MST; 275 FFT). Data were gathered during Routine Outcome Monitoring. The primary outcome was externalizing problem behavior (Child Behavior Checklist and Youth Self Report). Secondary outcomes were the proportion of adolescents living at home, engaged in school or work, and who lacked police contact during treatment. Because of the non-random assignment, a propensity score method was used to control for observed pre-treatment differences. Because the risk-need-responsivity (RNR) model guided treatment assignment, effectiveness was also estimated in youth with and without a court order as an indicator of their risk level. Looking at the whole sample, no difference in effect was found with regard to externalizing problems. For adolescents without a court order, effects on externalizing problems were larger after MST. Because many more adolescents with a court order were assigned to MST compared to FFT, the propensity score method could not balance the treatment groups in this subsample. In conclusion, few differences between MST and FFT were found. In line with the RNR model, higher risk adolescents were assigned to the more intensive treatment, namely MST. In the group with lower risk adolescents, this more intensive treatment was more effective in reducing externalizing problems.

    Oral streptococci detected in water from dental unit water lines (DUWLs) are a surrogate marker of patients' biological fluid retraction during therapy. We investigated oral streptococci detection rate in DUWLs in a representative sample of private offices in real-life conditions. Samples of nondisinfected water (100 ml) were collected from the DUWL designated for the air turbine handpiece in 81 dental units, immediately after dental treatment of patients with extensive air turbine handpiece use. Water was filtered and plated on a selective medium for oral streptococci and, morphologically, typical colonies of oral streptococci were counted. The lowest detection limit was 0.01 CFU/ml. The oral streptococci detection rate was 72% (95% CI: 62-81%), with a mean level of 0.7 CFU/ml. Oral streptococci detection was not affected by handpiece age or dental treatment type, but was associated with dental unit age. Biological fluid retraction into DUWLs during patient treatment and, possibly, the risk for patient-to-patient blood- or air-borne pathogen transmission are more frequent than expected.

    The duration of oral antibiotic acne therapy for adolescents compared with guidelines was recently investigated; however it was uncertain if duration of antibiotics for adult acne therapy differed. This study aimed to evaluate duration of oral antibiotics for adult acne compared with guidelines and determine possible cost-savings. This was a retrospective cohort study of MarketScan Commercial Claims and Encounters database that incorporated claims data to determine duration and costs of antibiotic treatment among adults ages 21 years and older. Of 17,448 courses, 84.5% (14,737) aligned with duration guidelines, although 12,040 (69.0%) courses did not include concomitant topical retinoid therapy. Mean savings of $592.26 per person could result if prolonged courses met guidelines. Mean (median) costs of generic and branded formulations for the most frequent course duration (90-179 days) were $103.77 ($54.27) and $1421.61 ($1462.25), respectively. Actual patient prescription adherence is uncertain and database lacks information regarding acne severity, patient physical characteristics, and clinical outcomes. The majority of oral antibiotic course durations follow guidelines, although topical retinoids are underused. Costs of antibiotic therapy were lower for shorter courses and those using generic medications; the cost-effectiveness of these modifications has not been investigated.

    We evaluated 50 consecutive patients who received thrombolytic therapy for acute myocardial infarction using thallium-201 single photon emission computed tomography in combination with oral dipyridamole to assess the frequency of residual myocardial ischemia. Thallium studies were performed early after myocardial infarction at a mean of 4.6 days. The time from the onset of chest pain to the administration of thrombolytic therapy was 2.6 hours (range 0.5 to 5.5). Q wave myocardial infarction was evident in 46 patients; four patients had a non-Q wave infarction (anterior infarction in 31 patients and inferior infarction in 19 patients). The serum mean peak creatinine kinase was 1503 IU/L (range 127 to 6500). Coronary angiography was performed in all patients at a mean of 3.1 days (range 2 to 10) and revealed the infarct-related vessel to be patent in 36 patients (72%). The ejection fraction was 48% (range 26% to 67%). After dipyridamole administration, 13 patients (26%) developed angina that was easily reversed with the administration of intravenous aminophylline. Systolic blood pressure decreased from 122 to 115 mm Hg (p less than 0.05) and the heart rate increased from 76 to 85 beats/min (p less than 0.05). None of the patients had significant hypotension, arrhythmias, or evidence of infarct extension. Perfusion abnormalities were present on the initial thallium images in 48 patients. Redistribution suggestive of ischemia was present in 36 patients (72%). Ischemia confined to the vascular distribution of the infarct vessel was evident in 22 patients. Seven patients had ischemia in the infarct zone as well as in a remote myocardial segment. Thus 29 patients (58%) had ischemia in the distribution of the infarct vessel. Ischemia in the infarct zone was evident in 19 of 36 patients with open infarct vessels and in 10 of 14 patients with occluded infarct vessels

    Full Text Available Although oral anticoagulant therapy (OAT is recommended for patients with atrial fibrillation (AF, it is widely underused among older patients, who are frequently prescribed antiplatelet therapy (APT instead. We assessed mortality and incidence of ischemic and hemorrhagic events according to prescription of OAT or APT in older medical in-patients with AF discharged from hospital. Stroke and bleeding risk were evaluated using the CHA2DS2-VASC (Congestive heart failure/ left ventricular dysfunction, Hypertension, Aged ≥75 years, Diabetes Mellitus, Stroke/transient ischemic attack/systemic embolism, Vascular Disease, Aged 65-74 years, Sex Category and HAS-BLED (Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile international normalized ratio, Elderly, Drugs/alcohol concomitantly scores. Comorbidity, cognitive status and functional autonomy were assessed using standardized scales. Association of OAT and APT with overall mortality, ischemic stroke and bleeding events was evaluated through multivariate analysis and propensity score matching. During a mean follow-up period of 11 months 384 of the 962 patients discharged (mean age 82.9±6.6 years, 59.1% female died (39.9%, 66 had an ischemic stroke and 49 experienced a major bleeding event. Compared with APT, OAT was associated with reduced overall mortality after multivariate analysis [odds ratio (OR 0.62, confidence interval (CI: 0.46-0.83] and after propensity score matched analysis (OR 0.65, CI: 0.52-0.82, P=0.0004, with a not significant reduced incidence of total and fatal ischemic stroke, and without increase in total, intracranial, major and fatal bleedings. In a sample of older AF patients with poor health status, OAT was associated with reduced mortality, without evidence of a significant increase in major or fatal bleedings.

    Full Text Available Abstract Background The aim of the study was to compare the prevalence and types of HIV-related oral lesions between children and adult Tanzanian patients on HAART with those not on HAART and to relate the occurrence of the lesions with anti-HIV drug regimen, clinical stage of HIV disease and CD4+ cell count. Methods Participants were 532 HIV infected patients, 51 children and 481 adults, 165 males and 367 females. Children were aged 2–17 years and adults 18 and 67 years. Participants were recruited consecutively at the Muhimbili National Hospital (MNH HIV clinic from October 2004 to September 2005. Investigations included; interviews, physical examinations, HIV testing and enumeration of CD4+ T cells. Results A total of 237 HIV-associated oral lesions were observed in 210 (39.5% patients. Oral candidiasis was the commonest (23.5%, followed by mucosal hyperpigmentation (4.7%. There was a significant difference in the occurrence of oral candidiasis (χ2 = 4.31; df = 1; p = 0.03 and parotid enlargement (χ2 = 36.5; df = 1; p = 0.04 between children and adults. Adult patients who were on HAART had a significantly lower risk of; oral lesions (OR = 0.32; 95% CI = 0.22 – 0.47; p = 0.005, oral candidiasis (OR = 0.28; 95% CI = 0.18 – 0.44; p = 0.003 and oral hairy leukoplakia (OR = 0.18; 95% CI = 0.04 – 0.85; p = 0.03. There was no significant reduction in occurrence of oral lesions in children on HAART (OR = 0.35; 95% CI = 0.11–1.14; p = 0.15. There was also a significant association between the presence of oral lesions and CD4+ cell count 3 (χ2 = 52.4; df = 2; p = 0.006 and with WHO clinical stage (χ2 = 121; df = 3; p = 0.008. Oral lesions were also associated with tobacco smoking (χ2 = 8.17; df = 2; p = 0.04. Conclusion Adult patients receiving HAART had a significantly lower prevalence of oral lesions, particularly oral candidiasis and oral hairy leukoplakia. There was no significant change in occurrence of oral lesions in children

    A simple, rapid, precise, accurate high performance liquid chromatography method has been developed and subsequently validated for determination of valsartan in rabbit plasma. The method was developed employing mixture of mobile phase consisting of 0.02 M potassium dihydrogen phosphate buffer and acetonitrile (45:55), pH was adjusted to 2.7 using 50% orthophosphoric acid and pumped thorough chromatographic system at a flow rate of 1 ml/min. An isocratic elution mode was carried out at HPLC system (Agilent Technologies, 1200 series, USA) fitted with variable wavelength detector and data processing software ChemStation. For sample analysis, 20 mul sample was injected and eluate was monitored at 225nm wavelength. Pharmacokinetic evaluation was performed in rabbits after the oral administration of valsartan loaded PVA-co-poly(AA) hydrogels. The mean Cmax of valsartan was 408.439ng/ml, Tmax was 12h and half life (t1/2) was 8.812h. The extraction procedure was simple with good response even at very low drug concentration, thereby making this method suitable for pharmacokinetic application. It is concluded that developed method is simple, fast, cost effective, and reproducible for the analysis of pharmacokinetic parameters in the rabbit plasma. (author)

    Currently, little evidence is available on the length and type of anticoagulation used for extended treatment for prevention of recurrent venous thromboembolism (VTE) in patients with unprovoked VTE who have completed initial oral anticoagulation therapy. To compare the efficacy and safety of available oral therapeutic options (aspirin, warfarin, direct oral anticoagulants (DOACs)) for extended thromboprophylaxis in adults with a first unprovoked VTE, to prevent VTE recurrence after completion of an acceptable initial oral anticoagulant treatment period, as defined in individual studies. For this review, the Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (March 2017) as well as the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 2). We also searched trials registries (March 2017) and reference lists of relevant articles. We included randomised controlled trials in which patients with a first, symptomatic, objectively confirmed, unprovoked VTE, who had been initially treated with anticoagulants, were randomised to extended prophylaxis (vitamin K antagonists (VKAs), antiplatelet agents, or DOACs) versus no prophylaxis or placebo. We also included trials that compared one type of extended prophylaxis versus another type of extended prophylaxis. Two review authors independently selected studies, assessed quality, and extracted data. We resolved disagreements by discussion. Six studies with a combined total of 3436 participants met the inclusion criteria. Five studies compared extended prophylaxis versus placebo: three compared warfarin versus placebo, and two compared aspirin versus placebo. One study compared one type of extended prophylaxis (rivaroxaban) versus another type of extended prophylaxis (aspirin). For extended prophylaxis versus placebo, we downgraded the quality of the evidence for recurrent VTE and all-cause mortality to moderate owing to concerns arising from risks of selection and performance bias

    This study investigated whether diffuse optical spectroscopy (DOS) measurements could assess clinical response to photodynamic therapy (PDT) in patients with head and neck squamous cell carcinoma (HNSCC). In addition, the correlation between parameters measured with DOS and the crosslinking of signal transducer and activator of transcription 3 (STAT3), a molecular marker for PDT-induced photoreaction, was investigated. Thirteen patients with early stage HNSCC received the photosensitizer 2-[1-hexyloxyethyl]-2-devinylpyropheophorbide-a (HPPH) and DOS measurements were performed before and after PDT in the operating room (OR). In addition, biopsies were acquired after PDT to assess the STAT3 crosslinking. Parameters measured with DOS, including blood volume fraction, blood oxygen saturation (StO2), HPPH concentration (cHPPH), HPPH fluorescence, and blood flow index (BFI), were compared to the pathologic response and the STAT3 crosslinking. The best individual predictor of pathological response was a change in cHPPH (sensitivity=60%, specificity=100%), while discrimination analysis using a two-parameter classifier (change in cHPPH and change in StO2) classified pathological response with 100% sensitivity and 100% specificity. BFI showed the best correlation with the crosslinking of STAT3. These results indicate that DOS-derived parameters can assess the clinical response in the OR, allowing for earlier reintervention if needed.

    Eliglustat is an investigational, oral substrate reduction therapy for Gaucher disease type 1 (GD1). Nineteen treatment-naïve patients have now completed 4years of an open-label study (NCT00358150). Mean hemoglobin level and platelet count increased by 2.3±1.5g/dL (baseline: 11.3±1.5g/dL) and 95% (baseline: 68,700±21,200/mm(3)), respectively. Mean spleen and liver volumes (multiples of normal, MN) decreased by 63% (baseline: 17.3±9.5 MN) and 28% (baseline: 1.7±0.4 MN), respectively. Median chitotriosidase and CCL-18 each decreased by 82%; plasma glucosylceramide and GM3 normalized. Mean bone mineral density T-score for the lumbar spine increased by 0.8 (60%) (baseline: -1.6±1.1). Femur dark marrow, a reflection of Gaucher cell infiltration into bone marrow, was reduced or stable in 17/18 patients. There were no bone crises. Most adverse events were mild and unrelated to treatment. These results extend the safety and efficacy of eliglustat reported at 1 and 2 years to 4 years. Copyright © 2014.

    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.

    To determine the clinical usefulness of basal-supported oral therapy (BOT) using insulin glargine in Japanese patients with type 2 diabetes. We compared HbA1c levels, body weight, and insulin doses before the introduction of BOT and in the final month of the observation period in 122 patients with type 2 diabetes who received BOT with insulin glargine between October 2007 and July 2009. To exclude the possible effects of seasonal changes in glycemic control, 57 of the 122 patients were followed-up for one year and examined for changes in HbA1c levels, body weight, and insulin dose. Examination of all cases (n=122) showed a significant decrease in HbA1c (before BOT: 8.7±1.8, after: 7.1±1.1%), but no significant change in body weight (before: 63.1±16.1, after: 63.8±17.0 kg). The mean observation period was 10.5±6.4 months. Insulin doses were significantly increased during the study. HbA1c levels improved significantly in patients on non-insulin-secreting drugs (biguanide, α-glucosidase inhibitor and thiazolidine derivatives) than those on insulin-secreting drugs (SU agents and glinides). BOT with insulin glargine is a useful strategy that can achieve good glycemic control in clinical practice without causing serious hypoglycemia. The introduction of BOT before exhaustion of pancreatic β cells may increase its effectiveness.

    Fragment-based drug design (FBDD) is a promising approach for the generation of lead molecules with enhanced activity and especially drug-like properties against therapeutic targets. Herein, we report the fragment-based drug design, systematic chemical synthesis and pharmacological evaluation of novel scaffolds as potent anticancer agents by utilizing six privileged fragments from known STAT3 inhibitors. Several new molecules such as compounds 5, 12, and 19 that may act as advanced chemical leads have been identified. The most potent compound 5 (HJC0123) has demonstrated to inhibit STAT3 promoter activity, downregulate phosphorylation of STAT3, increase the expression of cleaved caspase-3, inhibit cell cycle progression and promote apoptosis in breast and pancreatic cancer cells with low micromolar to nanomolar IC50 values. Furthermore, compound 5 significantly suppressed estrogen receptor (ER)-negative breast cancer MDA-MB-231 xenograft tumor growth in vivo (p.o.), indicating its great potential as an efficacious and orally bioavailable drug candidate for human cancer therapy.

    The early diagnosis of oral precancer and cancer is crucial and could have the highest impact on improving survival rates. A meta-analysis was conducted to compare the accuracy between the OralCDx brush biopsy and DNA-image cytometry in diagnosing both conditions. Bibliographic databases were systematically searched for original relevant studies on the early diagnosis of oral precancer and oral cancer. Study characteristics were evaluated to determine the accuracy of the two screening strategies. Thirteen studies (eight of OralCDx brush biopsy and five of DNA-image cytometry) were identified as having reported on 1981 oral mucosa lesions. The meta-analysis found that the area under the summary receiver operating characteristic curves of the OralCDx brush biopsy and DNA-image cytometry were 0.8879 and 0.9885, respectively. The pooled sensitivity, specificity, and diagnostic odds ratio of the OralCDx brush biopsy were 86% (95% CI 81-90), 81% (95% CI 78-85), and 20.36 (95% CI 2.72-152.67), respectively, while these modalities of DNA-image cytometry were 89% (95% CI 83-94), 99% (95% CI 97-100), and 446.08 (95% CI 73.36-2712.43), respectively. Results of a pairwise comparison between each modality demonstrated that specificity, area under the curve (AUC), and Q(∗) index of DNA-image cytometry was significantly higher than that of the OralCDx brush biopsy (Z=2.821, p0.05). In conclusion, the meta-analysis of the published studies indicated that DNA-image cytometry is more accurate than the OralCDx brush biopsy in diagnosing oral precancer and oral cancer.

    of diarrheic episodes in their children under 5 years of age, the degree of generalization, and the relationship with the social frame that sustains them. Material and methods. A sample of 300 families was randomly selected from a total of 15 740. Quantitative and qualitative information was gathered through structured open surveys. Non-parametric statistical analysis of the therapeutic practices was performed and their relationship with socioeconomic variables was analyzed. Results. The two practices considered to obstruct the oral rehydration therapy most, were common: infrequent use of oral rehydration serum (ORS and contraindicated medication. Non-parametric analysis indicated a significant relationship between contraindicated practices and a mistaken concept of dehydration. On the other hand, the relationship between a correct concept of dehydration and a using ORS, b not using contraindicated medication and c limiting the use of traditional medicine was also significant. Socioeconomic variables had no significant relationship with any particular practice nor with the concept of dehydration. Qualitative interpretation describes how the social meanings that sustain these practices are constructed and reproduced through social nets. Conclusions. The participation of health suppliers in the reproduction of therapeutic practices should be further investigated, as well as their relationship with the reproduction patterns of social meaning through the nets of social aid.

  4. Recombination methods for boron neutron capture therapy dosimetry

    The radiation effects of boron neutron capture therapy (BNCT) are associated with four-dose-compartment radiation field - boron dose (from 10 B(n,α) 7 Li) reaction), proton dose from 14 N(n,p) 14 C reaction, neutron dose (mainly fast and epithermal neutrons) and gamma-ray dose (external and from capture reaction 1 H(n,γ) 2 D). Because of this the relation between the absorbed dose and the biological effects is very complex and all the above mentioned absorbed dose components should be determined. From this point of view, the recombination chambers can be very useful instruments for characterization of the BNCT beams. They can be used for determination of gamma and high-LET dose components for the characterization of radiation quality of mixed radiation fields by recombination microdosimetric method (RMM). In present work, a graphite high-pressure recombination chamber filled with nitrogen, 10 BF 3 and tissue equivalent gas was used for studies on application of RMM for BNCT dosimetry. The use of these gases or their mixtures opens a possibility to design a recombination chamber for determination of the dose fractions due to gamma radiation, fast neutrons, neutron capture on nitrogen and high LET particles from (n, 10 B) reaction in simulated tissue with different content of 10 B.

    To evaluate (ii) whether inclusion of a single motivational interviewing (MI) session, as an adjunct to periodontal therapy, might be beneficial for preventing relapse in oral hygiene behaviours among patients treated for chronic periodontitis and (ii) whether individual and clinical characteristics can be of predictive value for retention of sufficient oral hygiene behaviours. This 3-year follow-up of a previously reported randomized controlled trial (RCT) study of 6-month duration included 26 patients. Patients in the test group had received one MI session by a clinical psychologist before initiation of the periodontal treatment. Otherwise, all patients followed the same treatment protocol for conventional educational intervention and non-surgical periodontal therapy. Efficacy variables assessed for evaluation of the standard of self-performed periodontal infection control were marginal bleeding index (MBI; primary efficacy variable) and plaque score (PI). The patterns of change in MBI and PI scores were similar for test and control groups over the observation period. At 3 years, both groups showed a desirable mean full-mouth MBI of 15%, a figure that was comparable to that at the short-term evaluation after active periodontal treatment. The post-treatment MBI was the only variable identified as a predictor of retained adequate oral hygiene behaviours. A single MI session as an adjunct to conventional periodontal therapy could not be proven to be of long-term beneficial additive effect with regard to prevention of relapse in oral hygiene behaviour. Desirable standard of self-performed infection control after active periodontal treatment predicted the retention of sufficient oral hygiene behaviour over time. © 2017 John Wiley & Sons A/S.

    and Overview. In 2005, the American Dental Association (ADA) Council on Scientific Affairs convened an expert panel to develop clinical recommendations for dentists treating patients who are receiving oral bisphosphonate therapy. The Journal of the American Dental Association published the resulting report in 2006. This 2008 advisory statement is the first of projected periodic updates of the 2006 clinical recommendations. This 2008 advisory statement concludes, on the basis of a review of the current literature, that for patients receiving bisphosphonate therapy, the risk of developing bisphosphonate-associated osteonecrosis (BON) of the jaw apparently remains low. It also newly concludes that current screening and diagnostic tests are unreliable for predicting a patient's risk of developing the condition. This statement updates the 2006 recommendations regarding general dentistry, management of periodontal diseases, implant placement and maintenance, oral and maxillofacial surgery, endodontics, restorative dentistry and prosthodontics, and orthodontics.

    Multimodality cancer therapy involving surgical resection, chemotherapy, and radiation therapy is frequently employed in the management of head and neck cancer. Patients who have undergone such therapy face substantial challenges during and after treatment. Prosthodontic rehabilitation is essential during and after tumor ablation to restore function, esthetics, and minimize interruption in daily routine. This clinical report describes the challenges faced by a patient undergoing multimodality therapy for a squamous cell carcinoma of the maxillary sinus and the stages involved in prosthodontic rehabilitation.

    Objective Unlike several other national health agencies, French health authorities recommended that the newer direct oral anticoagulant (DOAC) agents only be prescribed as second choice for the treatment of newly diagnosed non-valvular atrial fibrillation (NVAF), with vitamin K antagonists (VKA) remaining the first choice. We investigated the patterns of use of DOACs versus VKA in the treatment of NVAF in France over the first 5 years of DOAC availability. We also identified the changes in patient characteristics of those who initiated DOAC treatment over this time period. Methods Based on the French National Health Administrative Database, we constituted a population-based cohort of all patients who were newly treated for NVAF between January 2011 and December 2015. Trends in drug use were described as the percentage of patients initiating each drug at the time of treatment initiation. A multivariate analysis using logistic regression model was performed to identify independent sociodemographic and clinical predictors of initial anticoagulant choice. Results The cohort comprised 814 446 patients who had received a new anticoagulant treatment for NVAF. The proportion of patients using DOACs as initial anticoagulant therapy reached 54% 3 months after the Health Ministry approved the reimbursement of dabigatran for NVAF, and 61% by the end of 2015, versus VKA use. In the multivariate analysis, we found that DOAC initiators were younger and healthier overall than VKA initiators, and this tendency was reinforced over the 2011–2014 period. DOACs were more frequently prescribed by cardiologists in 2012 and after (adjusted OR in 2012: 2.47; 95% CI 2.40 to 2.54). Conclusion Despite recommendations from health authorities, DOACs have been rapidly and massively adopted as initial therapy for NVAF in France. Observational studies should account for the fact that patients selected to initiate DOAC treatment are healthier overall, as failure to do so may bias the risk

    Purpose: The criteria for administration of adjuvant radiation therapy (RT) in oral cavity squamous cell carcinoma (OSCC) remain controversial, and it is unclear whether patients with pT1-3N0 disease benefit from adjuvant radiation in the presence of free margins and perineural invasion. The goal of this report was to determine whether this group would benefit from adjuvant radiation therapy in terms of 5-year local control rate and overall survival rate. Methods and Materials: We retrospectively reviewed our case records from January 1996 to May 2005. In all, 460 pT1-3N0 OSCC patients had tumor-free margins, of whom 68 had perineural invasion. Postoperative adjuvant RT was performed in patients with pT4 tumors, positive lymph nodes, or close margins (≤4 mm). In addition, selected OSCC patients with large pT3 tumors or perineural invasion received postoperative adjuvant RT. Local control and overall survival rates were plotted by Kaplan-Meier analysis. Results: There were no significant differences in 5-year local control (p 0.1936) and overall survival (p = 0.5580) rates between patients with perineural invasion compared with those without. Among patients with perineural invasion, the addition of adjuvant radiotherapy did not significantly alter the 5-year local control rate (p = 0.3170) or the overall survival rate (p = 0.0935). Conclusion: Altogether, these data seem to indicate that radical surgical resection alone should be considered a sufficient treatment for OSCC patients with pT1-3N0 disease, even in the presence of perineural invasion

    Aim This study compared the changes on the subgingival microbiota of subjects with “refractory” periodontitis (RP) or treatable periodontitis (GR) before and after periodontal therapy by using the Human Oral Microbe Identification Microarray (HOMIM). Methods Individuals with chronic periodontitis were classified as RP (n=17) based on mean attachment loss (AL) and/or >3 sites with AL ≥2.5 mm after scaling and root planing, surgery and systemically administered amoxicillin and metronidazole or as GR (n=30) based on mean attachment gain and no sites with AL ≥2.5 mm after treatment. Subgingival plaque samples were taken at baseline and 15 months after treatment and analyzed for the presence of 300 species by HOMIM analysis. Significant differences in taxa before and after therapy were sought using the Wilcoxon test. Results The majority of species evaluated decreased in prevalence in both groups after treatment; however, only a small subset of organisms was significantly affected. Species that increased or persisted in high frequency in RP but were significantly reduced in GR included Bacteroidetes sp., Porphyromonas endodontalis, Porphyromonas gingivalis, Prevotella spp., Tannerella forsythia, Dialister spp., Selenomonas spp., Catonella morbi, Eubacterium spp., Filifactor alocis, Parvimonas micra, Peptostreptococcus sp. OT113, Fusobacterium sp. OT203, Pseudoramibacter alactolyticus, Streptococcus intermedius or Streptococcus constellatus and Shuttlesworthia satelles. In contrast, Capnocytophaga sputigena, Cardiobacterium hominis, Gemella haemolysans, Haemophilus parainfluenzae, Kingella oralis, Lautropia mirabilis, Neisseria elongata, Rothia dentocariosa, Streptococcus australis and Veillonella spp. were more associated with therapeutic success. Conclusion Persistence of putative and novel periodontal pathogens, as well as low prevalence of beneficial species was associated with chronic “refractory” periodontitis. PMID:22324467

    Melphalan followed by hematopoietic stem-cell transplantation (HSCT) is the standard treatment for multiple myeloma and other hematopoietic neoplasms. However, high doses of melphalan cause severe oral mucositis (OM). The objective was to verify the efficacy of cryotherapy plus laser therapy on reduction of OM severity. HSCT patients undergoing melphalan chemotherapy (n = 71) were randomly divided into two groups according to OM treatment: oral cryotherapy performed with ice chips for 1 h 35 min followed by low-level laser therapy (InGaAIP, 660 nm, 40 mW, 6 J/cm(2) ) (n = 54) and laser therapy alone with the same protocol (n = 17). A control group (n = 33) was composed of HSCT patients treated with melphalan who received no specific treatment for OM. OM scores and clinical information were collected from D0 to D + 11. The cryotherapy/laser therapy group showed the lowest OM scores (maximum Grade I) and the lowest mean number of days (8 days) with OM in comparison with the other groups (p cryotherapy with laser therapy was effective in reducing OM severity in HSCT patients who underwent melphalan conditioning.

    Full Text Available Objectives: The aim of this study was to evaluate the effect of a motivation and practical skills development methods on the oral hygiene of orphans. Material and Methods: Sixty eight orphans aged between 7 and 17 years from two orphanages in Kaunas were divided into two groups: practical application group and motivation group. Children were clinically examined by determining their oral hygiene status using Silness-Löe plaque index. Questionnaire was used to estimate the oral hygiene knowledge and practices at baseline and after 3 months. Statistical analysis included: Chi-square test (χ2, Fisher‘s exact test, Student‘s t-test, nonparametric Mann-Whitney test, Spearman’s rho correlation coefficient and Kappa coefficient. Results: All children had a plaque on at least one tooth in both groups: motivation 1.14 (SD 0.51, practical application 1.08 (SD 0.4 (P = 0.58. Girls in both groups showed significantly better oral hygiene than boys (P < 0.001. After 3 months educational program oral hygiene status improved in both groups significantly 0.4 (SD 0.35 (P < 0.001. Significantly better oral hygiene was determined in practical application group 0.19 (SD 0.27 in comparison with motivation group 0.55 (SD 0.32 (P < 0.001. By comparing results of first and second questionnaire surveys on use of soft drinks, the statistically significant decline of their use was in both groups (P = 0.004. Conclusions: Educational programs are effective in improving oral hygiene, especially when they’re based on practical skills training.

    Deferasirox is a recently approved once-daily oral iron chelator that has been shown to reduce liver iron concentrations and serum ferritin levels to a similar extent as infusional deferoxamine. To determine the cost effectiveness of deferasirox versus deferoxamine in patients with beta-thalassaemia major from a US healthcare system perspective. A Markov model was used to estimate the total additional lifetime costs and QALYs gained with deferasirox versus deferoxamine in patients with beta-thalassaemia major and chronic iron overload from blood transfusions. Patients were assumed to be 3 years of age at initiation of chelation therapy and to receive prescribed dosages of deferasirox and deferoxamine that have been shown to be similarly effective in such patients. Compliance with chelation therapy and probabilities of iron overload-related cardiac disease and death by degree of compliance were estimated using data from published studies. Costs ($US, year 2006 values) of deferoxamine administration and iron overload-related cardiac disease were based on analyses of health insurance claims of transfusion-dependent thalassaemia patients. Utilities were based on a study of patient preferences for oral versus infusional chelation therapy, as well as published literature. Probabilistic and deterministic sensitivity analyses were employed to examine the robustness of the results to key assumptions. Deferasirox resulted in a gain of 4.5 QALYs per patient at an additional expected lifetime cost of $US126,018 per patient; the cost per QALY gained was $US28,255. The cost effectiveness of deferasirox versus deferoxamine was sensitive to the estimated costs of deferoxamine administration and the quality-of-life benefit associated with oral versus infusional therapy. Cost effectiveness was also relatively sensitive to the equivalent daily dose of deferasirox, and the unit costs of deferasirox and deferoxamine, and was more favourable in younger patients.

    To evaluate predisposing factors such as orofacial manifestations, immunosuppression status and antiretroviral therapy in relation to oral colonization by Candida spp. in Brazilian HIV-infected children and their uninfected siblings in the era of highly active antiretroviral therapy (HAART). Whole stimulated saliva was collected from 65 HIV-infected children (HIV+) and 40 uninfected siblings (HIV-), followed by assessment of orofacial manifestation, caries indexes and the number of cavitated dentinal carious teeth (CDT). The salivary samples were cultured and the colonies were counted. After which they were identified by sugar assimilation and fermentation (API 20C). Data was analyzed using chi-square, Mann-Whitney, Spearman tests and logistic regression. Regarding positive growth, HIV+ presented 80% (52/65) and HIV- 57.5% (23/40) (P = 0.013). Absence of antiretroviral therapy and HAART increased the probability of Candida isolation (P oral candidiasis (OC) had no influence on Candida isolation. Mixed Candida spp. cultures were observed in HIV+ (40%) and HIV- (52%): C. albicans was more frequently found in both groups, with a higher prevalence in HIV+ (P = 0.05); other non-albicans species were isolated in HIV+ and HIV-. Low prevalence of orofacial manifestations was observed in HIV+ (10.7% of OC). There was an association between means of CDT and Candida growth (P children had a significantly higher prevalence of oral Candida spp. compared to their uninfected siblings. Absence of HAART and presence of dentinal carious teeth increased significantly Candida spp. colonization in these children.

    Cancer patients under treatment of head and neck tumors as well as those under chemotherapy for hematologic cancers, such as lymphoma and leukemia, and those about to receive bone marrow grafts, do require preventive oral and dental care (prior to cancer treatment), as well as oral care during and after oncological treatment. Furthermore, chemo and radiotherapy-related adverse effects are also common in patients with other types of cancer, with an estimated frequency of 10 per cent in adjuvant chemotherapy (QT), 40 per cent in primary QT, 80 per cent in bone marrow transplantation, in which myeloablative regimens are introduced, and 100 per cent in head and neck radiotherapy, in which the targeted fields are those of the oral cavity. The dentist, specialized in dental oncology, works within the multidisciplinary team at the great centers of cancer treatment, contributing to improve the quality of life of these patients. The present review of literature and of the Guidelines for Management of Oral Complications of Chemotherapy and Head and Neck Radiation (US National Cancer Institute) aims to inform the clinical oncologist, the radio therapist, and other professionals about the resources available in Oral Supportive Therapy in both the prevention and managements of such complications.

    Full Text Available Since the discovery of bone marrow mesenchymal stem cells (BMMSCs, many researchers have focused their attention on new sources of mesenchymal stem cells (MSCs. Consequently, MSCs that display self-renewal capacity, multidifferentiation potential and immunomodulatory properties have been isolated from human oral tissues, including tooth, periodontal ligament, and gingiva. Oral MSCs involve dental pulp stem cells (DPSCs, stem cells from exfoliated deciduous teeth (SHED, periodontal ligament stem cells (PDLSCs, dental follicle stem cells (DFCs, stem cells from apical papilla (SCAP and gingival stem cells (GMSCs. Current research on oral stem cells is expanding at an unprecedented rate. That being the case, a plethora of in vitro differentiation assays, immunodeficient animal transplantations and preclinical trials have demonstrated that these cells exhibit strong potential for both regenerative dentistry and medicine. Oral MSCs have proved their capability to repair cornea, dental pulp, periodontal, bone, cartilage, tendon, neural, muscle and endothelial tissues without neoplasm formation as well as to treat inflammatory diseases and immune disorders. This article describes the current understanding of oral MSCs and their prospective applications in cell-based therapy, tissue engineering and regenerative medicine. Special attention is placed on GMSCs as they are easily accessible and may be obtained in a convenient and minimally invasive way.

    Full Text Available The objective of the study is to evaluate the oral health problems on HIV youth patients from Galati. Materials and method. A cross-sectional study assessed 102 patients with mean age 22. The most frequent oral manifestations on HIV infected youth under ART are erythema marginatum, periodontitis, candidosis and hypertrophia gingivalis. Results and discussion. Dental decay-missing-filled index on HIV patients is high. Viral HIV replication, long time pediatric exposure on HIV, male sex, smoking, and oral inflamation are related to dental poor condition. Exodontic therapy is comon among HIV youth. However, persistence of some associated oral infections is related to individual or behavioral risk factors, but also to some newly found mechanisms, such as disfunctional immune reconstruction. Seeing to antiretroviral treatment, the severity and frequency of oral manifestations decreased among HIV patients on antiretroviral treatment. Conclusions. Developing medical, social and educational programs is imperative for improving the oral health of HIV youth of Galati.

    Full Text Available Data on the use of oral anticoagulation (OAC and antiplatelet therapy and the risk of bleeding and stroke amongst Asian patients with atrial fibrillation (AF are limited. We investigated the risks of bleeding and stroke with use of oral anticoagulation (OAC and antiplatelet therapy as mono- or combination therapy, in patients with AF from a Chinese nationwide cohort study.We studied a cohort of 10384 patients (57.2% men, age 67.8 ± 13.2 yrs between 1999 and 2010 from the National Health Insurance Research Database in Taiwan. Records of prescriptions were obtained during follow-up. The main outcome was a recurrent stroke during the follow-up period. Time-dependent Cox proportional hazards models were used for this analysis.We documented 1009 events for bleeding, as well as 224 hemorrhagic stroke and 1642 ischemic stroke events during a median 3.2 (interquartile range, 1.05-6.54 years' follow-up. Compared with warfarin users, patients with antiplatelet therapy had a lower risk of bleeding (adjusted relative risk [RR], 0.59, 95% confidence interval [CI], 0.49-0.71, p<0.001 whilst combination therapy had a non-statistically significant higher bleeding risk (RR, 1.33, 95%, 0.91-1.94, p = 0.20. Patients on antiplatelet monotherapy had a similar risk for ischemic stroke compared with OAC (RR 1.05, 95% CI, 0.89-1.25, p = 0.50, whilst those on combination therapy had a significantly higher risk (RR 1.90, 95% CI, 1.34-2.70, p<0.001.In a national representative cohort, antiplatelet therapy had no significant difference in ischemic stroke risk to warfarin. For bleeding, aspirin had a lower risk compared to warfarin. This may reflect poor anticoagulation control, highlighting important missed opportunities for improved stroke prevention, especially in countries where anticoagulation management is suboptimal.

Place and Duration of Study: Maharishi Markandeshwar College of Dental Science Research (MMCDSR), Ambala, India, from 2011 to 2014. Methodology: Immunohistochemistry was used to observe the N-cadherin expression in 100 cases having epithelium with normal oral mucosa, oral epithelial dysplastic lesions and oral squamous cell carcinoma (OSCC). For statistical significance, SPSS 13.0 was used to calculate the data by Mann-Whitney and Kruskal-Wallis tests. Results: In OSCC, N-cadherin expression was more evident than in oral epithelial dysplasia followed by the normal oral epithelium that did not show any dysplastic changes (p=0.001). Conversely, N-cadherin expression was not significant among the histological grade of OSCC. Conclusion: N-cadherin can be used as a potential biomarker for early diagnosis of OSCC. However, the N-cadherin expression did not show any correlation with the histological grade of OSCC. (author)

    Oral anticoagulation therapy requires regular blood testing to ensure therapeutic levels are maintained and excessive bleeding/clotting is avoided. Technology-assisted self-testing and management is seen as one of the key areas in which quality of care can be improved whilst reducing costs. Nevertheless, levels of patient engagement in self-testing and management remain low. To date, little research emphasis has been placed on understanding the patients' perspectives for low engagement. The typical approach adopted by healthcare providers is to provide patient education programmes, with the expectation that individual patients will change their behaviour and adopt new self-care strategies. However, if levels of patient engagement are to be increased, healthcare providers must also develop a better understanding of how their clinical service provision is perceived by patients and make adaptations. To explore patient views, needs and expectations of an anticoagulation service and the self-testing and management services provided. Interviews were conducted with 17 patients who currently engage in international normalised ratio (INR) self-testing and management. Thematic coding and analysis were carried out on the interview transcripts. Four high-level themes emerged from interviews: (i) role of clinic, (ii) motivations for self-testing, (iii) managing INR and (iv) trust. The clinic was seen as adding value in terms of specifying testing frequency, dosage profiles and calibrating equipment. Prompt communication from clinic to patient was also valued, although more personalised/real-time communication would help avoid feelings of isolation. Patients felt more in control as self-tester/managers and often took decisions about treatment adjustments themselves. However, some also manipulated their own test results to avoid 'unnecessary' interventions. More personalised/real-time communication, pragmatic and collaborative patient-clinician partnerships and recognition of

    Incidence rate of oral cancer in Changhua County is the highest among the 23 counties of Taiwan during 2001. However, in health data analysis, crude or adjusted incidence rates of a rare event (e.g., cancer) for small populations often exhibit high variances and are, thus, less reliable. We proposed a generalized Bayesian Maximum Entropy (GBME) analysis of spatiotemporal disease mapping under conditions of considerable data uncertainty. GBME was used to study the oral cancer population incidence in Changhua County (Taiwan). Methodologically, GBME is based on an epistematics principles framework and generates spatiotemporal estimates of oral cancer incidence rates. In a way, it accounts for the multi-sourced uncertainty of rates, including small population effects, and the composite space-time dependence of rare events in terms of an extended Poisson-based semivariogram. The results showed that GBME analysis alleviates the noises of oral cancer data from population size effect. Comparing to the raw incidence data, the maps of GBME-estimated results can identify high risk oral cancer regions in Changhua County, where the prevalence of betel quid chewing and cigarette smoking is relatively higher than the rest of the areas. GBME method is a valuable tool for spatiotemporal disease mapping under conditions of uncertainty. 2010 Elsevier Inc. All rights reserved.

    The aim of this study was to evaluate the effect of a motivation and practical skills development methods on the oral hygiene of orphans. Sixty eight orphans aged between 7 and 17 years from two orphanages in Kaunas were divided into two groups: practical application group and motivation group. Children were clinically examined by determining their oral hygiene status using Silness-Löe plaque index. Questionnaire was used to estimate the oral hygiene knowledge and practices at baseline and after 3 months. Statistical analysis included: Chi-square test (χ(2)), Fisher's exact test, Student's t-test, nonparametric Mann-Whitney test, Spearman's rho correlation coefficient and Kappa coefficient. All children had a plaque on at least one tooth in both groups: motivation 1.14 (SD 0.51), practical application 1.08 (SD 0.4) (P = 0.58). Girls in both groups showed significantly better oral hygiene than boys (P soft drinks, the statistically significant decline of their use was in both groups (P = 0.004). Educational programs are effective in improving oral hygiene, especially when they're based on practical skills training.

    Spontaneous intracerebral hemorrhage (ICH) is one type of the most devastating cerebrovascular diseases worldwide, which causes high morbidity and mortality. However, efficient treatment is still lacking. Stem cell therapy has shown good neuroprotective and neurorestorative effect in ICH and is a promising treatment. In this study, our aim was to review the therapeutic effects, strategies, related mechanisms and safety issues of various types of stem cell for ICH treatment. Numerous studies had demonstrated the therapeutic effects of diverse stem cell types in ICH. The potential mechanisms include tissue repair and replacement, neurotrophy, promotion of neurogenesis and angiogenesis, anti-apoptosis, immunoregulation and anti-inflammation and so forth. The microenvironment of the central nervous system (CNS) can also influence the effects of stem cell therapy. The detailed therapeutic strategies for ICH treatment such as cell type, the number of cells, time window, and the routes of medication delivery, varied greatly among different studies and had not been determined. Moreover, the safety issues of stem cell therapy for ICH should not be ignored. Stem cell therapy showed good therapeutic effect in ICH, making it a promising treatment. However, safety should be carefully evaluated, and more clinical trials are required before stem cell therapy can be extensively applied to clinical use.

    The implant-prosthetic rehabilitation of edentulous upper jaws has always been complex for surgeons and dentists. The lack of bone in both vertical and horizontal dimension does not allow the correct insertion of dental implants. In addition, patients with edentulous upper and lower arch have a loss of vertical dimension of the face and an aged expression. Many surgical techniques have been proposed to increase the bone volume, height and thickness, such as the Le Fort I osteotomy, the bone grafts and the placement of dental implants. Planning these surgical procedures is difficult, because it is not possible to reproduce the movements of osteotomized bone segments in three planes of space. This article describes the treatment of severe atrophy maxilla with a new approach using a new instrument named "Surgiplanner". Surgiplanner is a method that, only using a computerized axial tomography (CAT), allows to obtain a totally predetermined therapeutic result from both an aesthetic and functional point of view, with surgery of severe resorbed jaws. Surgiplanner allows repositioning of segment of the skeleton of the patient's face in a predetermined and controlled way for the best implant-supported oral rehabilitation.

    Laboratory tests to assess novel oral anticoagulants (NOACs) are under evaluation. Routine monitoring is unnecessary, but under special circumstances bioactivity assessment becomes crucial. We analyzed the effects of NOACs on coagulation tests and the availability of specific assays at different laboratories. Plasma samples spiked with dabigatran (Dabi; 120 and 300 μg/L) or rivaroxaban (Riva; 60, 146, and 305 μg/L) were sent to 115 and 38 European laboratories, respectively. International normalized ratio (INR) and activated partial thromboplastin time (APTT) were analyzed for all samples; thrombin time (TT) was analyzed specifically for Dabi and calibrated anti-activated factor X (anti-Xa) activity for Riva. We compared the results with patient samples. Results of Dabi samples were reported by 73 laboratories (13 INR and 9 APTT reagents) and Riva samples by 22 laboratories (5 INR and 4 APTT reagents). Both NOACs increased INR values; the increase was modest, albeit larger, for Dabi, with higher CV, especially with Quick (vs Owren) methods. Both NOACs dose-dependently prolonged the APTT. Again, the prolongation and CVs were larger for Dabi. The INR and APTT results varied reagent-dependently (P laboratories, respectively. The screening tests INR and APTT are suboptimal in assessing NOACs, having high reagent dependence and low sensitivity and specificity. They may provide information, if laboratories recognize their limitations. The variation will likely increase and the sensitivity differ in clinical samples. Specific assays measure NOACs accurately; however, few laboratories applied them. © 2013 American Association for Clinical Chemistry.

    Intrahepatic cholestasis of pregnancy predisposes women to liver disorders years after affected pregnancy. We compared the basal levels and responses of hyaluronic acid, a marker of liver fibrosis, and liver transaminases to postmenopausal hormone therapy in women with (n = 20) and without (n = 20) a history of intrahepatic cholestasis of pregnancy. This was a randomized, double-blind, placebo-controlled, crossover trial. Basal levels of hyaluronic acid were similar in both groups. Two weeks of oral estradiol 2.0 mg/day led to significant but similar (10.9% to 15.4%) rises in hyaluronic acid in both groups. Increasing the dose of oral estradiol to 4.0 mg/day resulted in normalization of the levels, whereas the addition of medroxyprogesterone acetate led to falls (11.0% to 10.7 %) in hyaluronic acid. Transdermal estradiol 50 microg led to a rise (3.2 %) in hyaluronic acid only in the control group. Other liver markers were normal at baseline and during hormone therapy. Normal basal levels and/or normal responses of hyaluronic acid and other liver markers to hormone therapy in women with previous intrahepatic cholestasis suggest that this therapy does not predispose these women to liver diseases.

    Chancroid is gaining importance as a sexually transmitted disease because of its association with transmission of human immunodeficiency virus type 1 (HIV-1). Effective, simply administered therapy for chancroid is necessary. Fleroxacin is effective against Haemophilus ducreyi in vitro. We performed an initial randomized clinical trial to assess the efficacy of fleroxacin for treatment of chancroid in Nairobi, Kenya. Fifty-three men with culture-positive chancroid were randomly assigned to receive either 200 mg (group 1) or 400 mg (group 2) of fleroxacin as a single oral dose. Groups 1 and 2 were similar with regard to severity of disease, bubo formation, and HIV-1 status. A satisfactory clinical response to therapy was noted in 23 of 26 patients (88%) in group 1 and 18 of 23 patients (78%) in group 2. Bacteriological failure occurred in 1 of 26 evaluable patients (4%) in group 1 and 4 of 23 evaluable patients (17%) in group 2. Two of 37 HIV-1-seronegative men (5%) and 3 of 11 HIV-1-infected men (27%) were bacteriological failures. Fleroxacin, 200 or 400 mg as a single oral dose, is efficacious therapy for microbiologically proven chancroid in patients who do not have concurrent HIV-1 infection. Among HIV-1-infected men, a single dose of 200 or 400 mg of fleroxacin is inadequate therapy for chancroid. PMID:2502065

    The existing methods for early and differential diagnosis of oral cancer are limited due to the unapparent early symptoms and the imperfect imaging examination methods. In this paper, the classification models of oral adenocarcinoma, carcinoma tissues and a control group with just four features are established by utilizing the hybrid Gaussian process (HGP) classification algorithm, with the introduction of the mechanisms of noise reduction and posterior probability. HGP shows much better performance in the experimental results. During the experimental process, oral tissues were divided into three groups, adenocarcinoma (n = 87), carcinoma (n = 100) and the control group (n = 134). The spectral data for these groups were collected. The prospective application of the proposed HGP classification method improved the diagnostic sensitivity to 56.35% and the specificity to about 70.00%, and resulted in a Matthews correlation coefficient (MCC) of 0.36. It is proved that the utilization of HGP in LRS detection analysis for the diagnosis of oral cancer gives accurate results. The prospect of application is also satisfactory. (paper)

    Anticoagulant therapy is prescribed for millions of patients worldwide for the prevention and treatment of both arterial and venous thrombosis. Historically, only vitamin K antagonists have been available for clinicians to prescribe. The anticoagulation landscape is changing. The recent availability of the novel oral anticoagulants overcome many of the disadvantages associated with vitamin K antagonists. However the lack of formal monitoring and clinic follow-up is a concern for clinicians, as medication adherence is being assumed, which is known to decline in patients prescribed medications for chronic conditions. The switching study is a programme of work investigating the association between medication adherence and patient's beliefs about anticoagulation therapy (warfarin and subsequently novel oral anticoagulants), together with beliefs about their illness and anticoagulation related quality of life. The anticoagulation database at King's College Hospital will be interrogated and two groups of patients will be identified; those with a time in therapeutic range on warfarin of ≥75 % and those beliefs about medications compared. Those patients in the time in therapeutic range beliefs about medications, re-evaluated on the novel agent. The results from these sub-studies, will inform a clinical pathway to support patients on these novel agents, which will be evaluated in an independent group of patients. The results from the switching study will be used to develop a clinical pathway to support patient's prescribed novel oral anticoagulant therapy long-term.

    Qualitative investigations have indicated that music therapy groups may be beneficial for bereaved teenagers. The existing relationship between young people and music serves as a platform for connectedness and emotional expression that is utilised within a therapeutic, support group format. This investigation confirms this suggestion through grounded theory analysis of focus group interviews. Changes in self-perception were not found as a result of participation, however practically significant results were found on adolescent coping. These cannot be generalized because of the small sample size. Grief specific tools are recommended for use in future investigations in order to capture the emotional impact of music therapy grief work with adolescents.

    Inequality between most Canadians and those from Inuit and First Nations communities, in terms of both access to oral health care services and related health outcomes, has been a long-standing problem. Efforts to close this equity gap led to the creation of dental therapy training programs. These programs were designed to produce graduates who would provide services in rural and northern communities. The closure of the last dental therapy program in late 2011 has ended the supply of dental therapists and governments do not appear to have any alternative solutions to the growing gap in access to oral health care services between most Canadians and those from Inuit and First Nations communities. A policy analysis of the rise and fall of the dental therapy profession in Canada was conducted using historical and policy documents. The analysis is framed within Kingdon's agenda-setting framework and considers why dental therapy was originally pursued as an option to ensure equitable access to oral health care for Inuit and First Nations communities and why this policy has now been abandoned with the closure of Canada's last dental therapy training school. The closure of the last dental therapy program in Canada has the potential to further reduce access to dental care in some Inuit and First Nations communities. Overlaps between federal and provincial jurisdiction have contributed to the absence of a coordinated policy approach to address the equity gap in access to dental care which will exacerbate the inequalities in comparison to the general population. The analysis suggests that while a technically feasible policy solution is available there continues to be no politically acceptable solution and thus it remains unlikely that a window of opportunity for policy change will open any time soon. In the absence of federal government leadership, the most viable option forward may be incremental policy change. Provincial governments could expand the scope of practice for

    Podoplanin is distinctively overexpressed in oral squamous cell carcinoma than oral benign neoplasms and plays a crucial role in the pathogenesis and metastasis of oral squamous cell carcinoma but its diagnostic application is quite limited. Here, we report a new near-infrared fluorescence imaging method using an indocyanine green (ICG)-labeled anti-podoplanin antibody and a desktop/a handheld ICG detection device for the visualization of oral squamous cell carcinoma-xenografted tumors in nude mice. Both near-infrared imaging methods using a desktop (in vivo imaging system: IVIS) and a handheld device (photodynamic eye: PDE) successfully detected oral squamous cell carcinoma tumors in nude mice in a podoplanin expression-dependent manner with comparable sensitivity. Of these 2 devices, only near-infrared imaging methods using a handheld device visualized oral squamous cell carcinoma xenografts in mice in real time. Furthermore, near-infrared imaging methods using the handheld device (PDE) could detect smaller podoplanin-positive oral squamous cell carcinoma tumors than a non-near-infrared, autofluorescence-based imaging method. Based on these results, a near-infrared imaging method using an ICG-labeled anti-podoplanin antibody and a handheld detection device (PDE) allows the sensitive, semiquantitative, and real-time imaging of oral squamous cell carcinoma tumors and therefore represents a useful tool for the detection and subsequent monitoring of malignant oral neoplasms in both preclinical and some clinical settings.

    Full Text Available Uterine fibroids (UFs are the most common tumors of the female genital tract. The effect of UFs on the quality of life and the overall cost of treatment are significant issues worldwide. Tumor size and location are the two specific factors which influence the occurrence of symptoms, the need for, and method of, treatment (some tumors require surgery while some can be treated with selected drugs. Primary prevention and treatment of early UF disease are worthy goals that might have a great impact on health care systems. Several treatments and prophylactic methods can be used in this endeavor. This publication presents current data about lesser-known substances which may have a beneficial effect on the treatment or prophylaxis of UFs and can be administered orally, serving as an alternative to (or complement of surgery or selective progesterone receptor modulators (SPRMs. Early prevention and treatment of UFs in women from high-risk groups should be our priority. Innovative forms of UF management are under intensive investigation and may be promising options in the near future. Many of them evaluated vitamin D, paricalcitol, epigallocatechin gallate (EGCG, elagolix, aromatase inhibitors (AIs, and cabergoline and deemed them to be safe and effective. The next step in such projects should be properly constructed randomized control trials (RCTs, carried out by successive phases.

    proportion of prescription fills for orally administered therapy without copayment increased from 15.0% to 53.0%, more than double the increase (12.3%-18.0%) in plans not subject to parity (P < .001). The proportion of patients with out-of-pocket spending of more than $100 per month increased from 8.4% to 11.1% compared with a slight decline from 12.0% to 11.7% in plans not subject to parity (P = .004). In plans subject to parity laws, estimated monthly out-of-pocket spending decreased by $19.44 at the 25th percentile, by $32.13 at the 50th percentile, and by $10.83 at the 75th percentile but increased at the 90th ($37.19) and 95th ($143.25) percentiles after parity (all P < .001, controlling for changes in plans not subject to parity). Parity laws did not increase 6-month total spending for users of any anticancer therapy or for users of oral anticancer therapy alone. While oral chemotherapy parity laws modestly improved financial protection for many patients without increasing total health care spending, these laws alone may be insufficient to ensure that patients are protected from high out-of-pocket medication costs.

  3. Triple Antithrombotic Therapy after Percutaneous Coronary Intervention (PCI in Patients with Indication for Oral Anticoagulation: Data from a Single Center Registry.

    Directory of Open Access Journals (Sweden)

    Dawid L Staudacher

    Full Text Available Antithrombotic therapy consisting of a dual anti-platelet therapy (DAPT and oral anti-coagulation (OAC with a vitamin k antagonist is often referred to as triple therapy. This combined anticoagulation is applied in patients undergoing coronary artery stent implantation while also having an indication for OAC. Triple therapy increases the risk for bleeding events compared to either DAPT or OAC alone and thereby might be associated with adverse outcomes. Clinical data on the frequency of bleeding events in patients on triple therapy from clinical trials derives from pre-selected patients and may differ from the real world patients. We report data on patient characteristics and bleeding incidence of patients dismissed on triple therapy from a single university hospital. Within the time span from January 2000 to December 2012, we identified a total of 213 patients undergoing PCI who were prescribed a triple therapy for at least 4 weeks (representing 0.86% of all patients treated. The usage of triple therapy significantly increased over the observed time period. The average CHA2DS2-VASc Score was 3.1 ± 1.1 with an average HAS-BLED score of 2.5 ± 0.86 representing a high-risk group for thromboembolic events as well as considerable risk for bleeding events. An on-treatment bleeding incidence of 9.4% was detected, with gastrointestinal and airway bleeding being the most frequent (5.1% and 1.4%, respectively. This is consistent with data from clinical trials and confirms the high risk of bleeding in patients on DAPT plus OAC. 29.0% of all patients receiving triple therapy had an indication for OAC other than non-valvular atrial fibrillation. This substantial patient group is underrepresented by clinical trials and needs further attention.

    The role of the p53 gene in the sensitivity of oral squamous cell carcinoma (SCC) to boron neutron capture therapy (BNCT) had not been studied. We examined the effect of boronophenylalanine (BPA)-mediated BNCT on oral SCC cells showing either wild-type p53 (SAS/neo) or mutated-type p53 (SAS/mp53). Survival ratio of cells was determined by colony formation. Cell viability was measured by MTT assay. Apoptotic cells were evaluated by flow cytometric analysis and nuclear DNA staining. When SAS/neo and SAS/mp53 cells were subjected to BNCT, more suppressive effects on colony formation and cell viability were observed in SAS/neo cells as compared with SAS/mp53. The proportion of apoptotic cells with DNA fragmentation was also increased in the cells with functional p53. These results suggest that oral SCC cells with mutated p53 cells are more resistant to BNCT than those with wild-type p53. BNCT must inhibit oral SCC cells in p53-dependent and p53-independent mechanisms. (author)

    To estimate cost-effectiveness of exenatide twice daily (BID) vs insulin glargine once daily (QD) as add-on therapy in Chinese type 2 diabetes patients not well controlled by oral anti-diabetic (OAD) agents. The Cardiff model was populated with data synthesized from three head-to-head randomized clinical trials of up to 30 weeks in China comparing exenatide BID vs insulin glargine as add-on therapies to oral therapies in the Chinese population. The Cardiff model generated outputs including macrovascular and microvascular complications, diabetes-specific mortality, costs, and quality-adjusted life years (QALYs). Cost and QALYs were estimated with a time horizon of 40 years at a discount rate of 3% from a societal perspective. Compared with insulin glargine plus OAD treatments, patients on exenatide BID plus OAD gained 1.88 QALYs, at an incremental cost saving of Chinese Renminbi (RMB) 114,593 (i.e., cost saving of RMB 61078/QALY). The cost-effectiveness results were robust to various sensitivity analyses including probabilistic sensitivity analysis. The variables with the most impact on incremental cost-effectiveness ratio included HbA1c level at baseline, health utilities decrement, and BMI at baseline. Compared with insulin glargine QD, exenatide BID as add-on therapy to OAD is a cost-effective treatment in Chinese patients inadequately controlled by OAD treatments.

    M3-specific inhibitors are currently preferred for anticholinergic therapy of OAB. However, not all of the patients profit from this regimen. This might reflect a heterogeneity of the patient group. The aim of this work is to define subgroups of patients with specific alterations of receptor expression and to profile the receptor expression individually. These receptor profiles might be used for the development of evidence-based "tailored" therapies. Detrusor probes from bladder carcinoma patients (BCa, n=9 F, n=7 male) and interstitial cystitis patients (IC, n=9 female) were examined using confocal immunofluorescence and PCR. M2, M3, P2X1-3, and H1-3 mRNAs were demonstrated in detrusor tissue. As revealed by immunofluorescence, the M2 receptor expression was significantly higher in female compared to male BCa tissues. In addition, the M2 receptor was further upregulated in IC vs BCa in female detrusor. IC patients showed specific alterations of their receptor profile. Individual receptor profiles might be used to optimize medicinal therapies.

    This is a phase III, prospective, randomized, double-blind, placebo-controlled clinical trial on lodenafil carbonate (LC), a novel phosphodiesterase 5 inhibitor developed in Brazil. Expanding information on LC efficacy and safety. International Index of Erectile Function (IIEF) erectile domain, positive answers to the sexual encounter profile (SEP)-2 and SEP-3 questions and incidence of adverse events (AEs). A total of 350 men with erectile dysfunction (ED) of all degrees were randomized to placebo, LC 40 mg or LC 80 mg and followed for 4 weeks. They completed the IIEF and answered the SEP questions 2 and 3 after each intercourse without and with the use of LC. IIEF Erectile Domain scores without and with the use of medication were the following (mean [M] +/- standard deviation [SD]): placebo = 13.9 +/- 5.2 and 14.8 +/- 7.8; LC 40 mg = 13.6 +/- 5.3 and 18.6 +/- 8.0; LC 80 mg = 13.4 +/- 4.9 and 20.6 +/- 7.7 (analysis of variance [ANOVA] P < 0.01). Positive answers to SEP-2 without and with the use of medication were the following (M +/- SD): placebo = 55.3 +/- 43.2% and 52.1 +/- 41.4%; LC 40 mg = 46.4 +/- 44.3% and 63.5 +/- 42.0%; LC 80 mg = 50.2 +/- 40.9% and 80.8 +/- 32.3% (ANOVA P < 0.01). Positive answers to SEP-3 were the following: placebo = 20.2 +/- 32.3% and 29.7 +/- 38.1%; LC 40 mg = 19.6 +/- 34.3% and 50.8 +/- 44.4%; LC 80 mg = 20.8 +/- 33.2% and 66.0 +/- 39.3% (ANOVA P < 0.01). The patients with at least one AE were placebo = 28.7%, LC 40 mg = 40.9%, and LC 80 mg = 49.5%. AEs whose incidence was significantly higher with LC than with placebo included rhinitis, headache, flushing, visual disorder, and dizziness. LC showed a satisfactory efficacy-safety profile for oral therapy of ED.

    Full Text Available Los glucocorticoides son usados comúnmente para el tratamiento de enfermedades inflamatorias, autoinmunes, enfermedades malignas, y en la prevención de rechazo de órganos trasplantados. Un efecto secundario frecuente del tratamiento prolongado es la pérdida de masa ósea que se produce por varios mecanismos y es causa de osteoporosis y fracturas vertebrales. El tratamiento con disfosfonatos ha sido propuesto para esta situación. Presentamos un caso clínico de osteoporosis grave en una niña con dermatomiositis juvenil, que respondió favorablemente al tratamiento con disfosfonatos orales.Glucocorticoids are used for the treatment of inflammatory and autoimmune diseases, cancer, and in prevention of organ rejects. A frequent secondary effect of longterm treatment with corticoids is the loss of bone mass, caused by several mechanisms: decrease in the intestinal calcium absorption, increase of the renal calcium excretion at the distal renal tubule, suppressive effect on the osteoblast and also in apoptosis of osteoclasts, inhibition in local production of IGF I (Insulin-like growth factor and IGFBPs (binding IGF I proteins necessary for bone metabolism, and decrease on osteocalcin production. Longterm treatment with corticoids is associated with osteoporosis and vertebral fractures. To improve this condition, treatment with bisphosphonates has been proposed. We present here a clinical case of a girl with dermatomyositis and severe osteoporosis with vertebral crushes, who responded well to oral bisphophonate treatment.

    Duration of oral antibiotic therapy in acne has not been widely studied. Recent guidelines suggest it should be limited to 3 to 6 months. We sought to compare the duration of oral antibiotic use with recent guidelines and determine the potential cost-savings related to shortened durations. This is a retrospective cohort study from the MarketScan Commercial Claims and Encounters database. Claims data were used to determine duration and costs of antibiotic therapy. The mean course duration was 129 days. The majority (93%) of courses were less than 9 months. Among the 31,634 courses, 18,280 (57.8%) did not include concomitant topical retinoid therapy. The mean (95% confidence interval) duration with and without topical retinoid use was 133 (131.5-134.7) days and 127 (125.4-127.9) days, respectively. The mean excess direct cost of antibiotic treatment for longer than 6 months was $580.99/person. Claims cannot be attributed to a specific diagnosis or provider. The database does not provide information on acne severity. Duration of antibiotic use is decreasing when compared with previous data. However, 5547 (17.53%) courses exceeded 6 months, highlighting an opportunity for reduced antibiotic use. If courses greater than 6 months were shortened to 6 months, savings would be $580.99/person.

    In a prespecified subgroup analysis of participants not on statin therapy at baseline in the TACT, a high-dose complex oral multivitamins and multimineral regimen was found to have a large unexpected benefit compared with placebo. The regimen tested was substantially different from any vitamin regimen tested in prior clinical trials. To explore these results, we performed detailed additional analyses of participants not on statins at enrollment in TACT. TACT was a factorial trial testing chelation treatments and a 28-component high-dose oral multivitamins and multiminerals regimen versus placebo in post-myocardial infarction (MI) patients 50 years or older. There were 460 (27%) of 1,708 TACT participants not taking statins at baseline, 224 (49%) were in the active vitamin group and 236 (51%) were in the placebo group. Patients were enrolled at 134 sites around the United States and Canada. Daily high-dose oral multivitamins and multiminerals (6 tablets, active or placebo). The primary end point of TACT was time to the first occurrence of any component of the composite end point: all-cause mortality, MI, stroke, coronary revascularization, or hospitalization for angina. The primary end point occurred in 137 nonstatin participants (30%), of which 51 (23%) of 224 were in the active group and 86 (36%) of 236 were taking placebo (hazard ratio, 0.62; 95% confidence interval, 0.44-0.87; P=.006). Results in the key TACT secondary end point, a combination of cardiovascular mortality, stroke, or recurrent MI, was consistent in favoring the active vitamin group (hazard ratio, 0.46; 95% confidence interval, 0.28-0.75; P=.002). Multiple end point analyses were consistent with these results. High-dose oral multivitamin and multimineral supplementation seem to decrease combined cardiac events in a stable, post-MI population not taking statin therapy at baseline. These unexpected findings are being retested in the ongoing TACT2. Copyright © 2017 The Authors. Published by Elsevier

    We examined how the use of bone turnover markers and educational information affects persistence of bisphosphonate use in osteoporotic patients. We found that reporting bone turnover results and/or educational information did not affect persistence. Long-term adherence and persistence to osteoporosis medication are poor. We examined whether reporting of bone turnover marker results, education about osteoporosis, or a combination of both would increase persistence to oral bisphosphonates. Two hundred and forty women who were 5 years postmenopausal with BMD at least 2.0 standard deviations below normal were recruited for the study. All women were given a new prescription for alendronate and randomly assigned to one of four groups: (1) bone marker results at baseline, 3 and 12 months; (2) educational materials every month and a membership in the National Osteoporosis Foundation; (3) bone marker and educational information; and (4) control, no information other than usual care. Persistence among randomization groups was tested using survival analysis adjusting for the delay between intervention methods. Of those filling their initial prescription, 95.5% refilled their prescription at the end of the first month, 87% at 3 months, 82% at 6 months, and 78% at 10 months. Overall persistence through 12 months was 54%. There was no difference found among the four groups for persistence time using (p > 0.58). Providing bone turnover marker results is not an effective way to enhance early compliance and persistence with drug therapy. While the women in our study felt that bone marker results and educational information were helpful to them, there was no difference in persistence between those who received either bone marker information and/or educational information and those who did not. Because of the unexpected rate of primary nonadherence, this study may be underpowered.

The biofilm formed on a solid base such as the enamel of the teeth, fillings, restorations, orthodontic appliances or obturators is dental plaque. Disturbance of homeostasis of biofilm, excessive growth or increase in the number of acid-forming bacteria leads to the development of the most common diseases of the oral cavity, i.e. dental caries and periodontal disease.
