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.

Obstructive sleep apnea is a prevalent sleep disorder among older adults. Oral appliances are increasingly prescribed as therapy for obstructive sleep apnea. Adherence to oral appliance therapy is highly variable. Based on value-expectancy theory and other social-psychological theories, adherence to oral appliance therapy may be influenced by patients' perceived effectiveness of the therapy, self-efficacy, and availability of social support. We examined these perceptions among older adults with obstructive sleep apnea who were prescribed oral appliance therapy. We mailed surveys to all patients aged ≥65 years who had been prescribed oral appliance therapy for obstructive sleep apnea over the prior 36 months at a Veterans Affairs medical center. We examined frequencies of responses to items that assessed perceived effectiveness, self-efficacy, and social support for nightly use of oral appliances from friends, family, or health care staff. Thirty-nine individuals responded (response rate, 30%; mean [SD] age 71.4 [SD 6.3] years; 97% male). Thirty-six percent of the respondents perceived regular use of oral appliance therapy to be effective in managing obstructive sleep apnea; 39% agreed that they felt confident about using oral appliances regularly; 41% felt supported by people in their life in using oral appliance therapy; and 38% agreed that health care staff would help them to use their oral appliance regularly. These rates represented less than half of respondents despite the finding that 65% of patients believed that they would use their oral appliance regularly. Although oral appliance therapy is increasingly prescribed for obstructive sleep apnea, only about one third of older adults prescribed it perceived it to be an effective treatment, were confident about oral appliance use, and/or believed that they would receive needed support. Future research is needed to better understand older adults' perceptions so that interventions can be designed to improve the

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.

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. PMID:28708091

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.

Refractory overactive bladder: Beyond oral anticholinergic therapy

Glinski, Ronald W.; Siegel, Steven

2007-01-01

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 aim of this study was to evaluate the effects of non-surgical periodontal therapy on intra-oral halitosis 3 months after therapy. Sixty-eight adults with intra-oral halitosis were included in a case series. Intra-oral halitosis was evaluated at baseline, and at 3 months after treatment using the organoleptic scores (OLS), Halimeter ® , and a gas chromatograph. Significant reductions for OLS (p < 0.01), total sum of volatile sulphur compounds (T-VSC) (p < 0.01) and methyl mercaptan (MM) (p < 0.05) values were found after treatment. Hydrogen sulphide (H 2 S) levels were not significantly reduced. The numbers of probing pockets 4 mm, 5 mm and 6 mm were significantly reduced as a result of therapy (p < 0.001). Bleeding on probing (BOP) and plaque indices were also significantly reduced (p < 0.001). For the 34 individuals with successful periodontal treatment (BOP<20% and a ≥50% reduction of total pocket depth) reductions in OLS (p < 0.01) and T-VSC scores (p < 0.01) were found. Eleven individuals were considered effectively treated for intra-oral halitosis presenting with a T-VSC value <160 ppb, a H 2 S value <112 ppb and a MM value <26 ppb. Non-surgical periodontal therapy resulted in reduction of OLS, MM and T-VSC values 3 months after therapy. Few individuals were considered as effectively treated for intra-oral halitosis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The oral mucositis is the most frequent acute oral complication resulting from antineoplastic treatment and may worsen the clinical condition of the patient and interfere with his/her quality of life. This study aimed to comparatively evaluate, from a clinical point of view, the effect of Laser Therapy λ660 nm (wavelength of the red Laser) and λ830 nm (wavelength of the infrared Laser), at extra-oral points, in remission of severity of oral mucositis and pain associated with it in pediatric oncological patients undergoing chemotherapy with the anticancer drug methotrexate, noting which of the two wavelength is the most appropriate to this new technique. The sample consisted of 13 patients placed at random in each group and subjected to sessions of Low Level Laser Therapy, at pre-determined extra-oral points for five consecutive days, starting at the beginning of the observation of mucositis injuries. It became possible to note that from the group of patients in the group of Laser λ830 nm ( n = 6; 46.15%), four ( n = 4; 66.67%) of these patients had remission of injuries to grade 0 (WHO), and as for pain, five patients ( n = 5; 83.33%) showed no painful symptoms for mucositis injuries. In the Laser λ660 nm group ( n = 7; 53.85%), only two patients ( n = 2; 28.57%) achieved a regression of lesions to grade 0 (WHO), while four patients ( n = 4; 57.14%) had no pain. So, the extra-oral application of Laser Therapy was effective in treating injuries of oral mucositis in the patients treated; and Laser Therapy in the infrared spectrum (λ830 nm) was more effective in the treatment of oral mucositis injuries compared to the red spectrum (λ660 nm), which can be explained by the greater power of penetration of infrared rays, acting in a more expressive way in deeper places.

The potential management of oral candidiasis using anti-biofilm therapies.

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.

Oral leukoplakia is a pre-malignant lesion of the oral mucosa. The aim of this study is to compare the curative effects of photodynamic therapy and cryotherapy in the treatment of oral leukoplakia. The first group, treated by photodynamic therapy (δ-aminolevulinic acid (ALA), 630-635 nm wavelength), consisted of 48 patients suffering from leukoplakia. The second group consisted of 37 patients treated using cryotherapy. Analyses and comparisons of the complete responses, recurrences, numbers of procedures and adverse effects after both PDT and cryotherapy were obtained. In the first group, a complete response was obtained in 35 patients (72.9%), with thirteen recurrences observed (27.1%) over a six-month period. In the second group, a complete response was obtained in 33 patients (89.2%), and recurrence was observed in nine patients (24.3%). Photodynamic therapy and cryotherapy appear to be comparative methods of treatment that may both serve as alternatives for the traditional surgical treatment of oral leukoplakia. The advantages of PDT are connected with minimally invasive and localized character of the treatment and with not damage of collagenous tissue structures, therefore normal cells will repopulate these arrangements. PDT is more convenient for patients, less painful, and more esthetic. Copyright © 2011 Elsevier B.V. All rights reserved.

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.

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

There are no data in children with type 2 diabetes (T2D) regarding the durability of glycemic control with oral medication. Therefore, we assessed the likelihood of and time to failure of oral therapy in children and adolescents diagnosed with T2D. Charts of patients presenting to our large tertiary-care children's hospital between January 2000 and June 2007 with a new diagnosis of diabetes (n = 1625) were reviewed to identify those with T2D (n = 184). Subjects' initial therapy, hemoglobin A1c (HbA1c), body mass index, age, gender, and antibody status were documented, as well as subsequent therapies and HbA1c values, to determine whether baseline characteristics predicted future insulin dependence. Kaplan-Meier survival curves and Cox proportional hazards analysis demonstrated time to failure of oral therapy. Eighty-nine patients remained on insulin throughout the study. Baseline characteristics that determined future insulin dependence included being placed on insulin initially, initial HbA1c and race (whites less likely to be insulin dependent at study conclusion). Patients who failed oral therapy were more often reported to be non-compliant or unable to tolerate metformin than those who continued on oral therapy. The median time to failure of oral therapy (metformin monotherapy in 84/95) was not significantly different for patients initially treated with oral therapy (42 months) and insulin (35 months). Thus, children with T2D appear to fail oral therapy more quickly than what is reported in adults. It is not yet known if improving compliance with treatment might allow more children to remain on oral medications. © 2012 John Wiley & Sons A/S.

Many anesthesiologists are reluctant to depart from their traditional long fasting periods, even though many guidelines recommend that oral intake of clear fluids administered up to 2-3 hours prior to general anesthesia does not adversely affect the gastric contents. It also indicates that the application of these guidelines does not affect the incidence of pulmonary aspiration. One of the reasons why they have not changed their practices is that they wonder whether it is safe to administer clear fluids as recommended in the guidelines. In this review, we emphasize that oral rehydration therapy using clear fluids (such as OS-1, water and carbohydrate-rich beverage) is safe based on the non-invasive gastric echo examinations as many guidelines have already indicated. Oral rehydration therapy should be considered not only as an alternative to intravenous therapy for preoperative fluid and electrolyte management but also as one of the important modalities which can enhance the recovery of surgical patients.

Dysfunction of the gastrointestinal tract has now been recognized to affect all stages of Parkinson’s disease (PD). The consequences lead to problems with absorption of oral medication, erratic treatment response, as well as silent aspiration, which is one of the key risk factors in developing pneumonia. The issue is further complicated by other gut abnormalities, such as small intestinal bacterial overgrowth (SIBO) and an altered gut microbiota, which occur in PD with variable frequency. Clinically, these gastrointestinal abnormalities might be associated with symptoms such as nausea, early-morning “off”, and frequent motor and non-motor fluctuations. Therefore, non-oral therapies that avoid the gastrointestinal system seem a rational option to overcome the problems of oral therapies in PD. Hence, several non-oral strategies have now been actively investigated and developed. The transdermal rotigotine patch, infusion therapies with apomorphine, intrajejunal levodopa, and the apomorphine pen strategy are currently in clinical use with a few others in development. In this review, we discuss and summarize the most recent developments in this field with a focus on non-oral dopaminergic strategies (excluding surgical interventions such as deep brain stimulation) in development or to be licensed for management of PD.

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.

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 anticoagulation therapy with warfarin is the mainstay of prevention and treatment of thromboembolic disease. However, it remains one of the leading causes of harmful medication errors and medication-related adverse events. The beneficial outcomes of oral anticoagulation therapy are directly dependent upon the quality of dose and anticoagulation management, but the literature is not robust with regards to what constitutes such management. This review focuses on, and attempts to define, the parameters of high-quality anticoagulation management and identifies the appropriate outcome measures constituting high-quality management. Elements discussed include the most fundamental measure, time in therapeutic range, along with other parameters including therapy initiation, time to therapeutic range, dosing management when patients are not in therapeutic range, perioperative dosing management, patient education, and other important outcome measures. Healthcare providers who manage oral anticoagulation therapy should utilize these parameters as a measure of their performance in an effort to achieve high-quality anticoagulation management.

Subjects (n = 188) with type 2 diabetes and inadequate response to two oral medications (A1C >8.0%) were randomly assigned to treatment with either a third oral medication or an insulin 70/30 mix b.i.d. plus metformin for a comparison of efficacy, safety, and cost. The protocol called for aggressive dose titration to achieve target values of fasting blood glucose (80-120 mg/dl), postprandial glucose (<160 mg/dl), and A1C (<7%). These efficacy parameters were evaluated at weeks 2, 6, 12, and 24 of therapy. If dose adjustments failed to achieve targeted glycemic control, subjects were switched to an alternate therapy. At the end of study (week 24 of therapy), A1C and fasting plasma glucose (FPG) values showed comparable decreases in the two treatment groups. Only 31% (oral therapy) and 32% (insulin plus metformin) of subjects achieved target values of A1C (<7%). A total of 10 of the 98 subjects randomized to triple oral therapy (10.2%) who failed to improve sufficiently were switched to insulin therapy. An additional four subjects dropped out of the oral treatment group due to adverse events felt to be potentially drug related. Only two of the subjects randomized to insulin plus metformin had to be switched to basal-bolus regimens (regular insulin and NPH insulin). Cost analysis determined that insulin plus metformin (mean cost 3.20 dollars/day) provided efficacy equal to that of a triple oral drug regimen (10.40 dollars/day). Insulin 70/30 mix plus metformin was as effective as triple oral therapy in lowering A1C and FPG values. The triple oral regimen was not as cost effective, and a high percentage of subjects (total of 16.3%) did not complete this regimen due to lack of efficacy or side effects.

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.

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.

Purpose Oral targeted therapies represent a significant advance for the treatment of patients with chronic lymphocytic leukemia (CLL); however, their high cost has raised concerns about affordability and the economic impact on society. Our objective was to project the future prevalence and cost burden of CLL in the era of oral targeted therapies in the United States. Methods We developed a simulation model that evaluated the evolving management of CLL from 2011 to 2025: chemoimmunotherapy (CIT) as the standard of care before 2014, oral targeted therapies for patients with del(17p) and relapsed CLL from 2014, and for first-line treatment from 2016 onward. A comparator scenario also was simulated where CIT remained the standard of care throughout. Disease progression and survival parameters for each therapy were based on published clinical trials. Results The number of people living with CLL in the United States is projected to increase from 128,000 in 2011 to 199,000 by 2025 (55% increase) due to improved survival; meanwhile, the annual cost of CLL management will increase from $0.74 billion to $5.13 billion (590% increase). The per-patient lifetime cost of CLL treatment will increase from $147,000 to $604,000 (310% increase) as oral targeted therapies become the first-line treatment. For patients enrolled in Medicare, the corresponding total out-of-pocket cost will increase from $9,200 to $57,000 (520% increase). Compared with the CIT scenario, oral targeted therapies resulted in an incremental cost-effectiveness ratio of $189,000 per quality-adjusted life-year. Conclusion The increased benefit and cost of oral targeted therapies is projected to enhance CLL survivorship but can impose a substantial financial burden on both patients and payers. More sustainable pricing strategies for targeted therapies are needed to avoid financial toxicity to patients. PMID:27870563

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.

One of the most important decisions in the treatment of osteoarticular infections is the time at which parenteral therapy can be changed to oral therapy. C-reactive protein (CRP) is an acute inflammatory indicator with a half-life of 19 hours and thus can be helpful in assessing the adequacy of therapy for bacterial infections. At our institution, a combination of CRP and clinical findings is used to determine the transition to oral therapy. A search of 8 years of electronic records identified children with osteoarticular infections. Only children with culture-positive acute bacterial arthritis (ABA) or acute bacterial osteomyelitis (ABO) were studied further. A primary chart review of demographic and clinical data was conducted, and a secondary chart review of complicated outcomes was performed. Of 194 total patients, complicated outcomes occurred in 40, of which 35 were prolonged therapy. Only 1 microbiologic failure occurred, presumably due to a retained intra-articular fragment of infected bone. CRP was highest initially among patients with simultaneous ABO + ABA and among those with complicated outcomes, and was lower at the transition to oral therapy in the complicated outcome group (1.5 vs 2.1 mg/dL; P = .012). The combination of clinical findings and CRP is a useful tool to transition children with osteoarticular infections to oral therapy. Complicated outcomes were associated with higher early CRP at diagnosis and lower CRP at the end of parenteral therapy, suggesting that clinicians were more conservative with prolonged initial parenteral therapy in this group.

Histoplasmosis is a usually asymptomatic deep fungal infection of tropical origin with respiratory entry and possible oral, pharyngeal, or metastatic localization. The condition represents an important imported systemic mycosis with oral involvement. We report the case of a patient who developed an oropharyngeal reactivation of a latent Histoplasma infection after receiving local antitumoral radiation therapy of the neck. H capsulatum was shown to be present in the lesion by both histopathology and staining, and was deduced to be the causative organism of the disease.

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 <14 days at Palmetto Health Hospitals in Columbia, SC, from 1 January 2010 through 31 December 2013 and discharged on oral 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, <75%). Kaplan-Meier analysis and multivariate Cox proportional hazards regression were used to examine treatment failure. Among the 362 patients, high, moderate and low bioavailability oral 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.

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. Itmore » 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.« less

Prospects in the Application of Photodynamic Therapy in Oral Cancer and Premalignant Lesions

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.

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.

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. PMID:24455744

The purpose of this study was to clarify the efficacy and toxicities of re-irradiation using proton beam therapy combined with weekly intra-arterial chemotherapy for recurrent oral cancer. Between October 2009 and July 2014, 34 patients who had recurrent oral cancer were treated by proton beam therapy combined with intra-arterial infusion chemotherapy at the Southern Tohoku Proton Therapy Center, Japan. For all patients, the median follow-up was 25 months (range, 3-77 months). After treatment, 22 patients (65%) achieved a complete response, and 12 patients (35%) achieved a partial response at the primary tumor site. One-year and 2-year overall survival (OS) rates were 62% and 42%, respectively. One-year and 2-year LC rates were 77% and 60%, respectively. No treatment-related deaths were observed during the treatment and follow-up periods. Re-irradiation using proton beam therapy combined with weekly intra-arterial chemotherapy improved OS and local control rates compared with other treatment modalities and could become a new treatment modality for patients with recurrent oral cancer. © 2016 John Wiley & Sons Australia, Ltd.

To conduct a quasi-experimental comparison of early clinical outcomes between injectable, sustained-release, depot naltrexone formulation versus oral naltrexone maintenance therapy in individuals with opiate dependence. Early retention in treatment and urine-confirmed opiate use in the first 8 weeks postdetoxification were compared between patients (diagnosed as opiate-dependent according to DSM-IV criteria) participating in 2 concurrently run randomized clinical trials of oral (n = 69; patients treated from September 1999 to May 2002) and long-acting injectable (n = 42; patients treated from November 2000 to June 2003) naltrexone maintenance therapy with psychosocial therapy. Long-acting injectable naltrexone produced significantly better outcome than oral naltrexone on days retained in treatment (F(1,106) = 6.49, P = .012) and for 1 measure of opiate use (F(1,106) = 5.26, P = .024); other measures were not significantly different, but differences were in the same direction. In subanalyses, there were interaction effects between baseline heroin use severity and type of treatment. In subanalyses, heroin users with more severe baseline use showed better retention with oral naltrexone maintenance therapy combined with intensive psychotherapy (behavioral naltrexone therapy) as compared to retention shown by severe heroin users treated with long-acting naltrexone injections combined with standard cognitive-behavioral therapy (χ²(1)= 9.31, P = .002); less severe heroin users evidenced better outcomes when treated with long-acting injectable naltrexone. This quasi-experimental analysis provides tentative indications of superior outcomes for heroin-dependent patients treated with long-acting injectable naltrexone compared to oral naltrexone. The finding that heroin users with more severe baseline use achieved better outcomes with oral naltrexone is most probably attributable to the intensive nature of the psychosocial treatments provided and points to the opportunity

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

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.

Oral mucositis is a debilitating and dose limiting side effect of oncotherapy in cancer patients. Low Level Laser Therapy (LLLT) is a promising new intervention for the treatment of oral mucositis. Aims and objectives: 1. Perform a systematic review of available literature on the therapeutic effect of LLLT on established oral mucositis. 2. Formulate recommendations for future studies based on results of review. Methods: Electronic search oflow level laser therapy in the treatment of oral mucositis was conducted and eligible studies reviewed. Results: Four studies met the inclusion criteria and were analyzed. A total of 109 patients were included, 59 of which received LLLT as a therapeutic measure. An overall success rate of 81.4% success rate was reported in regard to OM. Conclusion: The review demonstrated the positive therapeutic effect of LLLT on oral mucositis. However, the need for future studies with standardized reporting of parameters and methods is needed to increase the level of evidence of this intervention.

Oral amiodarone was administered to 38 patients (25 males, 13 females) with mean age of 43.6 years. Ventricular and supraventricular arrhythmias were present in 30 and 8 patients respectively. Amiodarone was given as 400-1200 mg/day for 1-2 weeks as loading dose and then it was maintained as 100-600 mg/day. The mean duration of therapy was 12.4 months. Adverse effects were noted in 21 (55.3%) cases. The commonest adverse effects observed were asymptomatic corneal microdeposits followed by gastrointestinal, cardiac, neurological and cutaneous disturbances. The drug was withdrawn in 2 (5.3%) patients because of nausea and vomiting. One patient died of pulmonary infiltrations. It is concluded that adverse effects are common with amiodarone but are tolerated well, making this drug an excellent choice for treatment of cardiac arrhythmias.

This review is one of a suite of six Cochrane reviews looking at the primary medical management options for patients with chronic rhinosinusitis.Chronic rhinosinusitis is a common condition involving inflammation of the lining of the nose and paranasal sinuses. It is characterised by nasal blockage and nasal discharge, facial pressure/pain and loss of sense of smell. The condition can occur with or without nasal polyps. Oral corticosteroids are used to control the inflammatory response and improve symptoms. To assess the effects of a short course of oral corticosteroids as an adjunct ('add-on') therapy in people with chronic rhinosinusitis who are already on standard treatments. The Cochrane ENT Information Specialist searched the Cochrane ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2015, Issue 7); MEDLINE; EMBASE; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 11 August 2015. Randomised controlled trials (RCTs) comparing a short course (up to 21 days) of oral corticosteroids to placebo or no treatment, where all patients were also receiving pharmacological treatment for chronic rhinosinusitis. We used the standard methodological procedures expected by Cochrane. Our primary outcomes were disease-specific health-related quality of life (HRQL), patient-reported disease severity, and the adverse event of mood or behavioural disturbances. Secondary outcomes included general HRQL, endoscopic nasal polyp score, computerised tomography (CT) scan score, and the adverse events of insomnia, gastrointestinal disturbances and osteoporosis. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. Two trials with a total of 78 participants met the inclusion criteria. Both the populations and the 'standard' treatments differed in the two studies. Oral steroids as an adjunct to intranasal corticosteroids One trial in adults with nasal polyps

No guidelines for supportive drug therapy have been established for oral mucositis occurring during cancer chemotherapy. We retrospectively examined the progression of oral mucositis in 91 patients with breast cancer who received the 5-fluorouracil, epirubicin, and cyclophosphamide (FEC)-100 regimen between September 2007 and August 2008. Daily rebamipide was administered to patients with oral mucositis as per hospital protocol to evaluate the hypothesized preventive and mucosal protective effects of rebamipide(Mucosta®). Oral mucositis was observed in 43 patients (47%)during 4 courses of FEC. The median age of the patients was 55 years(range, 32-76 years). Of the 91 patients, 49 patients who did not receive rebamipide during the 4 FEC courses were classified as group A, 14 patients who received rebamipide before the start of FEC were classified as group B, and 28 patients who received rebamipide after developing oral mucositis were classified as group C. The incidence of oral mucositis at the start of FEC with or without rebamipide administration was observed in 5 patients in group B (36%) and 38 patients in groups A and C (49%) (p=0.3472). The mucositis grade was G1 in 4 patients and G2 in 1 patient in group B, and G1 in 20 patients and G2 plus G3 in 18 patients in groups A and C (p=0.2467). In group C, the grade decreased in 25 patients (89%) and did not occur (G0) in 17 patients (61%) during the next course, and 15 patients (54%) continued to the final course without any occurrence of mucositis. These results suggest that rebamipide is effective for the treatment of oral mucositis. Although significant differences were not observed in the groups, rebamipide has the potential to prevent development of oral mucositis and alleviate its symptoms, and seems promising as a new supportive drug therapy. We hope to verify the preventive and protective effects of rebamipide by conducting a prospective, randomized trial while treating oral mucositis with basic oral care

Progressive resistance to antimicrobial agents has reduced options for gonorrhea therapy worldwide. Solithromycin (CEM-101) is a novel oral fluoroketolide antimicrobial with substantial in vitro activity against Neisseria gonorrhoeae. We conducted a phase 2 trial of 2 oral doses of solithromycin (1200 and 1000 mg) for treatment of uncomplicated gonorrhea. A total of 59 participants were enrolled and treated in this trial; 28 participants received 1200 mg of solithromycin and 31 received 1000 mg. Forty-six (78%) participants had positive cultures for N. gonorrhoeae at the time of enrollment: 24 of the 28 persons (86%) who received 1200 mg of oral solithromycin, and 22 of 31 (71%) who received 1000 mg. In addition, 8 participants had positive pharyngeal gonococcal cultures, and 4 had positive rectal cultures. All patients with positive cultures for N. gonorrhoeae were cured at all sites of infection. Chlamydia trachomatis and Mycoplasma genitalium coinfections were evaluated using nucleic acid amplification tests and were negative at 1 week of follow-up in 9 of 11 (82%) participants positive for C. trachomatis and 7 of 10 (70%) participants positive for M. genitalium. Mild dose-related gastrointestinal side effects (nausea, loose stools, vomiting) were common but did not limit therapy. Oral single-dose solithromycin, in doses of 1000 mg and 1200 mg, was 100% effective for treatment of culture-proven gonorrhea at genital, oral, and rectal sites of infection and is a promising new agent for gonorrhea treatment.

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

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.

There is a high rate of schizophrenic patients who do not adhere to their prescribed therapy, despite the implementation of antipsychotic long-acting injections and the introduction of atypical antipsychotics. The aim of this study was to investigate the differences in sociodemographic, clinical and medication adherence variables between the two groups of schizophrenic patients on maintenance therapy with depot antipsychotic fluphenazine decanoate and oral antipsychotics only as well as a correlation between the medication adherence and other examined variables. A total of 56 patients of both genders, aged < 60 years, with the diagnosis of schizophrenia (F20) (ICD-10, 1992) clinically stable for at least 6 months were introduced in this cross-sectional study. The patients from the depot group (n = 19) were on classical depot antipsychotic fluphenazine decanoate administering intramuscularly every 4 weeks (with or without oral antipsychotic augmentation) and the patients from the oral group (n = 37) were on oral therapy alone with classical or atypical antipsychotics, either as monotherapy or combined. The Positive and Negative Syndrome Scale (PANSS) was used to assess symptom severity. Item G12 of the PANSS was used to assess insight into the illness. The patients completed the Medical Adherence Rating Scale (MARS) was used to assess adherence to the therapy. A higher MARS score indicates behavior [Medical Adherence Questionnaire (MAQ subscale)] and attitudes toward medication [Drug Attitude Inventory (DAI subscale)] that are more consistent with treatment adherence. The exclusion criteria were determined. The Pearson's chi2 test was used to compare categorical variables, Student's t-test to compare continuous variables and Pearson's correlation to test the correlation significance; p = 0.05. Significant between-group differences in age, illness duration, chlorpromazine equivalents, PANSS score and DAI subscore were found. Item G12 of the PANSS subscore and MARS

We present results of four years in oral rehydration therapy (ORT) in the Hospital Infantil del Estado de Sonora. There was 10.2 consults by diarrhoea for day. Children lower of one year old received oral rehydration therapy in 86.8%, were included 11% of prolonged diarrhoea and 32.3% of children with malnutrition. During the procedure diarrhoea there was complicated in 3% with paralytic ileus sepsis and pneumonia. Effectivity of ORT was in 90.9%; 92.8% in light dehydration and 78.7% moderate. Failure in 8.6% was due to vomitus, no acceptation of the oral solution, abundant evacuations and other complication presented. Were observed reduction in hospitalization, rate of 19.2% in 1986 to 38.4% in 1989. The diarrheal mortality decreased in the Urgence Department in 42% and in the Infectology Department in 54%. We considered these results as satisfactory, but are susceptible to better when we diffuse more the oral rehydration therapy in own region.

The prednisone, etoposide, procarbazine and cyclophosphamide (PEP-C) oral combination chemotherapy regimen (prednisone 20 mg, cyclophosphamide 50 mg, etoposide 50 mg, and procarbazine 50 mg with an oral anti-emetic) was employed at our center to treat 22 patients with heavily pretreated, recurrent mantle cell lymphoma (MCL). All medications were administered daily until leukocytes fell to <3.0 x 10(9)/L whereupon treatment was withheld until recovery from the nadir. Therapy was then reinstituted on a daily, alternate day, or fractionated basis (e.g. 5 of 7 days) depending on patient tolerance. Doses given per day were held constant. Eighty-two percent achieved an objective response with 46% complete responses and 36% partial responses. Median time on therapy was 17 months. The regimen was well tolerated. Our findings demonstrate that low-dose oral agents administered in combination for continuous, prolonged periods with minimal drug-free intervals (metronomic therapy) may represent a novel, effective, easily tolerated approach to MCL and that this treatment approach warrants further exploration.

The in vitro effect of a novel, oligosaccharide nanomedicine OligoG against oral pathogen-related biofilms, both alone and in the presence of the conventional anti-bacterial agent triclosan, was evaluated. The effect of OligoG±triclosan was assessed against established Streptococcus mutans and Porphyromonas gingivalis biofilms by bacterial counts and image analysis using LIVE/DEAD(®) staining and atomic force microscopy (AFM). The effect of triclosan and OligoG surface pre-treatments on bacterial attachment to titanium and polymethylmethacrylate was also studied. OligoG potentiated the antimicrobial effect of triclosan, particularly when used in combination at 0.3% against S. mutans grown in artificial saliva. OligoG was less effective against established P. gingivalis biofilms. However, attachment of P. gingivalis, to titanium in particular, was significantly reduced after surface pre-treatment with OligoG and triclosan at 0.01% when compared to controls. Light microscopy and AFM showed that OligoG was biocidal to P. gingivalis, but not S. mutans. OligoG and triclosan when used in combination produced an enhanced antimicrobial effect against two important oral pathogens and reduced bacterial attachment to dental materials such as titanium, even at reduced triclosan concentrations. Whilst the use of triclosan against oral bacteria has been widely documented, its synergistic use with OligoG described here, has not previously been reported. The use of lower concentrations of triclosan, if used in combination therapy with OligoG, could have environmental benefits. The potentiation of antimicrobial agents by naturally occurring oligomers such as OligoG may represent a novel, safe adjunct to conventional oral hygiene and periodontal therapy. The ability of OligoG to inhibit the growth and impair bacterial adherence highlights its potential in the management of peri-implantitis. Copyright © 2013 Elsevier Ltd. All rights reserved.

Ganciclovir. A pharmacoeconomic review of its use as intravenous or oral maintenance therapy in the management of cytomegalovirus retinitis in patients with AIDS.

PubMed

Perry, C M; Davis, R

1997-08-01

Cytomegalovirus retinitis, an opportunistic infection caused by the herpesvirus cytomegalovirus, is a major cause of illness in patients with advanced AIDS. As infected patients require long term drug treatment to delay disease progression and minimise loss of vision, the disease is associated with substantial treatment costs which considerably increase overall expenditure on AIDS-related health care. During the last decade, intravenous ganciclovir has been a mainstay of treatment for patients with cytomegalovirus retinitis. However, notwithstanding its demonstrated efficacy as maintenance therapy for this condition, long term intravenous drug administration is both inconvenient and uncomfortable for many patients. Moreover, neutropenia and catheter-related infections have been reported commonly in patients receiving ganciclovir via the intravenous route. To overcome the limitations of intravenous ganciclovir, an oral formulation of the drug has been developed for use as maintenance therapy. In comparative clinical trials, both intravenous and oral ganciclovir maintenance therapy slowed disease progression and preserved visual acuity in patients with stabilised cytomegalo-virus retinitis, although there was evidence that the intravenous formulation was more effective in terms of delaying recurrence of active disease. This suggests that oral ganciclovir use should be limited to the treatment of patients without evidence of immediately sight-threatening cytomegalovirus retinitis. Three published cost analyses, which were based on efficacy and tolerability data derived from 2 randomised, comparative clinical trials, have shown that oral ganciclovir maintenance therapy offers cost advantages over intravenous maintenance therapy, despite the higher acquisition cost of the oral formulation. The higher overall costs of intravenous maintenance treatment, compared with oral therapy, were attributed to higher drug administration and adverse event treatment costs. In one

Cost-effectiveness of combined oral bisphosphonate therapy and falls prevention exercise for fracture prevention in the USA.

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

Ketoconazole, a new oral imidazole derivative, was employed for the treatment of five patients with paracoccidioidomycosis. The response was excellent, with objective clinical improvement and healing of both mucocutaneous and pulmonary lesions. Mycological and serological tests, as well as delayed hypersensitivity, were assessed and found to correlate with clinical improvement. Therapy was conducted for 12 months with a dose of 200 mg day in 2 patients; in the remainder the dose was reduced (100 mg day) after the first 6 months and maintained as such for an equal period. No side-effects or toxicity were noted despite prolonged treatment. The advantages of the new therapeutic approach are discussed.

To evaluate the efficacy and complications of oral and intravenous fluid therapy in newborns with hypernatremic dehydration. A total of 75 term and near-term (>35 weeks) neonates with hypernatremic dehydration (Na ≥ 150 mmol/L) were included in this retrospective study. The patients were divided into two groups according to therapy approach for rehydration (breast milk-oral formula and intravenous fluid). The decline in sodium concentration (<0.5 mmol/L/h was regarded as safe drop) and complications were analyzed. The mean gestational age, birth weight and age at admission were 38.9 ± 1.4(36-42) weeks, 3341 ± 504 (2500-4500) gram and 4.3 ± 2.6 (1-17) day, respectively. Fever (61.8%) and jaundice (39.4%) were the most common presenting signs. Forty-four (58.6%) of the infants were treated with breast milk and/or oral formula (group 1) and 31 (41.4%) of the infants were treated with IV fluid (group 2). In group 1 and group 2, respectively, mean % weight loss, 5 and 7.5; median serum sodium at admission, 153 and 152 mmol/L; median change in sodium at 12 hours, 7 and 11 mmol/L; and median change in sodium at 24 hours, 10 and 15 mmol/L. The decline in sodium concentration was more safely in group 1 than group 2 at both 12 and 24 hours of rehydration. One patient had convulsion associated with cerebral edema in group 2. Otherwise no complication was observed in both groups. Enteral route for fluid replacement may be safe and effective and may be an alternative to intravenous fluid therapy in newborns with hypernatremic dehydration when clinical situation is stable.

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.

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.

Oral squamous cell carcinoma ranks among the top ten most common cancers worldwide. Despite the success in diagnosis and therapy during the past 30 years, oral squamous cell carcinoma still belongs to the tumor types with a very unfavorable prognosis. In an effort to identify genomic alterations with prognostic relevance, we applied the comparative genomic hybridization technique on oral squamous cell carcinoma. The tumors exhibited from five up to 47 DNA copy number alterations, indicating a considerable degree of genomic imbalance. Out of 35 tumors, 19 showed a gain of chromosome band 7p12. Genomic imbalances were investigated by hierarchical cluster analysis and clustered image mapping to investigate whether genomic profiles correlate with clinical data. Results of the present investigation show that profiling of genomic imbalances in general, and especially of the epidermal growth factor receptor (EGFR) on 7p12, may be suitable as prognostic factors. In order to identify small-molecule inhibitors for EGFR, we established a database of 531 natural compounds derived from medicinal plants used in traditional Chinese medicine. Candidate compounds were identified by correlation analysis using the Kendall tau-test of IC50 values of tumor cell lines and microarray-based EGFR mRNA expression. Further validation was performed by molecular docking studies using the AutoDock program with the crystal structure of EGFR tyrosine kinase domain as docking template. We estimate these results will be a further step toward the ultimate goal of individualized, patient-adapted tumor treatment based on tumor molecular profiling.

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.

There is an increasing trend towards using oral systemic therapy in patients with cancer. Compared to parenteral therapy, oral cancer agents offer convenience, have similar efficacy, and are preferred by patients, consequently making its use appealing in older adults. However, adherence is required to ensure its efficacy and to avoid compromising treatment outcomes, especially when the treatment goal is curative, or in case of symptomatic/rapidly progressing disease, where dose-intensity is important. This opens a new challenge for clinicians, as optimizing patient adherence is challenging, particularly due to lack of consensus and scarcity of available clinical evidence. This manuscript aims to review the impact of age-related factors on adherence, summarize the evidence on adherence, recommend methods for selecting patients suitable for oral cancer agents, and advise monitoring interventions to promote adherence to treatment.

[Oral tocolytic therapy with clenbuterol--clinical facts].

1988-01-01

Clenbuterol is a betamimetic agent with a marked effect on the adrenergic beta-2-receptors relevant for tocolysis. The influence on beta-1-receptors of the heart, resulting in cardiovascular side effects is far less. The substance is resorbed almost completely enterally and has a half-life of 34 hours. Consequently, ingestion intervals of 12 hours are possible, resulting in a good acceptance of the tocolytic, therapy and a noticeable improvement of the patients compliance. Clenbuterol was applied in 37 cases in the course of a clinical test. Initially, the dose was 0.04 mg b.i.d., after 24 hours 0.02 mg b.i.d. In cases of cervix-effective, premature labor, an objectively measureable tocolytic effect was achieved. Subjectively reported side effects, i.e. palpation, tachycardia and tremor, were noticeably weaker than under fenoterol therapy. There was no indication of clenbuterol-related cardiotoxicity regarding continuous measurement of heart-specific enzymes, i.e. CK-MB and serum myoglobin. No pathologic alterations were found in the EKGs. Therefore, regarding indications and contraindications for beta-adrenergic agents, clenbuterol appears to have good tocolytic properties, with the advantages of less cardiac side effects, better compliance and a better dose-effect-ratio compared with the common oral tocolysis with fenoterol.

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.

The process of creating and administering traditional tagged anatomy laboratory examinations is time consuming for instructors and limits laboratory access for students. Depending on class size and the number of class, sections, creating, administering, and breaking down a tagged laboratory examination may involve one to two eight-hour days. During the time that a tagged examination is being created, student productivity may be reduced as the anatomy laboratory is inaccessible to students. Further, the type of questions that can be asked in a tagged laboratory examination may limit student assessment to lower level cognitive abilities and may limit the instructors' ability to assess the students' understanding of anatomical and clinical concepts. Anatomy is a foundational science in the Physical Therapy curriculum and a thorough understanding of anatomy is necessary to progress through the subsequent clinical courses. Physical therapy curricula have evolved to reflect the changing role of physical therapists to primary caregivers by introducing a greater scope of clinical courses earlier in the curriculum. Physical therapy students must have a thorough understanding of clinical anatomy early in the education process. However, traditional anatomy examination methods may not be reflective of the clinical thought processes required of physical therapy students. Traditional laboratory examination methods also reduce student productivity by limiting access during examination set-up and breakdown. To provide a greater complexity of questions and reduced overall laboratory time required for examinations, the Physical Therapy Program at Mercer University has introduced oral laboratory examinations for the gross anatomy course series. © 2012 American Association of Anatomists.

Field-cancerized tissue can give rise to second primary tumours, causing therapeutic failure. Boron neutron capture therapy (BNCT) is based on biological targeting and would serve to treat undetectable foci of malignant transformation. The aim of this study was to optimize BNCT for the integral treatment for oral cancer, with particular emphasis on the inhibitory effect on tumour development originating in precancerous conditions, and radiotoxicity of different BNCT protocols in a hamster cheek pouch oral precancer model.

Background. Ulcerative proctitis (UP) is typically treated initially with oral 5-aminosalicylate ("5-ASA"), mesalamine suppository, or mesalamine enema ("UP Rx"). Little is known about their effectiveness in practice. Methods. Using a US health insurance database, we identified new-onset UP patients between January 1, 2005, and December 31, 2007, based on the following: (1) initiation of UP Rx; (2) endoscopy in prior 30 days resulting in diagnosis of UP; and (3) no prior encounters for ulcerative colitis or Crohn's disease. We examined the incidence of therapy escalation and total costs in relation to initial UP Rx. Results. We identified 548 patients: 327 received mesalamine suppository, 138 received oral 5-ASA, and 83 received mesalamine enema, as initial UP Rx. One-third receiving oral 5-ASA experienced therapy escalation over 12 months, 21% for both mesalamine suppository and enema. Mean cumulative total cost of UP Rx over 12 months was $1552, $996, and $986 for patients beginning therapy with oral 5-ASA, mesalamine enema, and mesalamine suppository, respectively. Contrary to expert recommendations the treatments were often not continued prophylactically. Conclusions. Treatment escalation was common, and total costs of therapy were higher, in patients who initiated treatment with oral 5-ASA. Further study is necessary to assess the significance of these observations.

The aim of this study was to compare the oral health status of chronic renal failure (CRF) patients on renal replacement therapy with a matched reference population. Cross-sectional study. Forty-two dentate CRF patients--aged 25-52 years old--were matched with a reference group of 808 dentate subjects. The oral health was assessed using decayed missing filled (DMF) indices, simplified oral hygiene index and periodontal status. An oral health questionnaire was used to assess self-reported dental problems. Student t-tests and chi-square tests were performed to compare the CRF patients with the controls. All index-scores in the CRF patients were comparable with the controls except for number of teeth covered with calculus that was significantly higher (P < 0.05) in CRF patients (4.1 +/- 2.6) than in controls (3.0 +/- 2.9). The self-reported oral health questionnaire revealed a trend for increased temporomandibular complaints in CRF patients (16.7%vs 5.7% in controls; P = 0.06) as well as bad taste (31.0%vs 6.8% in controls, P = 0.08). For most dental aspects, the oral health of CRF patients is comparable with controls.

Searching for more effective and selective therapies for head and neck cancer, we demonstrated the therapeutic effect of boron neutron capture therapy (BNCT) to treat oral cancer and inhibit long-term tumor development from field-cancerized tissue in the hamster cheek pouch model. However, BNCT-induced mucositis in field-cancerized tissue was dose limiting. In a clinical scenario, oral mucositis affects patients' treatment and quality of life. Our aim was to evaluate different radioprotectors, seeking to reduce the incidence of BNCT-induced severe mucositis in field-cancerized tissue. Cancerized pouches treated with BNCT mediated by boronophenylalanine at 5 Gy were treated as follows: control: saline solution; Hishigh : histamine 5 mg kg(-1) ; Hislow : histamine 1 mg kg(-1) ; and JNJ7777120: 10 mg kg(-1). Hislow reduced the incidence of severe mucositis in field-cancerized tissue to 17% vs 55%; Hishigh : 67%; JNJ7777120: 57%. Hislow was non-toxic and did not compromise the long-term therapeutic effect of BNCT or alter gross boron concentration. Histamine reduces BNCT-induced mucositis in experimental oral precancer without jeopardizing therapeutic efficacy. The fact that both histamine and boronophenylalanine are approved for use in humans bridges the gap between experimental work and potential clinical application to reduce BNCT-induced radiotoxicity in patients with head and neck cancer. © 2015 John Wiley & Sons A/S.

The literature reports various treatment methodologies, such as trans-oral laser microsurgery, radiation therapy, total/partial laryngectomies, and concurrent radiation chemotherapy for patients with early larynx cancer. However, at the forefront of early glottis treatment is trans-oral laser microsurgery and radiation therapy, likely due to better functional and survival outcomes. Here we conduct the largest Canadian head-to-head comparison of consecutive patients treated with either radiation therapy or trans-oral laser microsurgery. Additionally, we compare these two treatments and their 5-year survival rates post treatment to add to the existing literature. Charts of patients who were diagnosed with early glottic cancer between 2006 and 2013 were reviewed. Seventy-five patients were identified, and split into 2 groups based on their primary treatment, trans-oral laser microsurgery and radiation therapy. Kaplan-Meier survival curves, life-tables, and the log-rank statistic were reported to determine if there was a difference between the two treatment groups and their disease-specific survival, disease-free survival, and total laryngectomy-free survival. Additionally, each different survival analysis was stratified by potential confounding variables, to help conclude which treatment is more efficacious in this population. The 5-year disease-specific survival rate is 93.3 % σ = 0.063 and 90.8 % σ = 0.056 for patients treated with trans-oral laser microsurgery and radiation therapy, respectively (χ (2) < 0.001, p = 0.983). The disease free survival rate is 60.0 % (σ =0.121) for patients treated with trans-oral laser microsurgery, and 67.2 % (σ = 0.074) for those who received RT (χ (2) = 0.19, p = 0.663). Additionally, the total laryngectomy-free survival rate is 84.1 % (σ = 0.1) and 79.1 % (σ = 0.072) for patients' early glottic cancer treated by trans-oral laser microsurgery and radiation therapy, respectively (�

Introduction: Since the previous parameter and review paper publication on oral appliances (OAs) in 2006, the relevant scientific literature has grown considerably, particularly in relation to clinical outcomes. The purpose of this new guideline is to replace the previous and update recommendations for the use of OAs in the treatment of obstructive sleep apnea (OSA) and snoring. Methods: The American Academy of Sleep Medicine (AASM) and American Academy of Dental Sleep Medicine (AADSM) commissioned a seven-member task force. A systematic review of the literature was performed and a modified Grading of Recommendations Assessment, Development, and Evaluation (GRADE) process was used to assess the quality of evidence. The task force developed recommendations and assigned strengths based on the quality of the evidence counterbalanced by an assessment of the relative benefit of the treatment versus the potential harms. The AASM and AADSM Board of Directors approved the final guideline recommendations. Recommendations: We recommend that sleep physicians prescribe oral appliances, rather than no therapy, for adult patients who request treatment of primary snoring (without obstructive sleep apnea). (STANDARD) When oral appliance therapy is prescribed by a sleep physician for an adult patient with obstructive sleep apnea, we suggest that a qualified dentist use a custom, titratable appliance over non-custom oral devices. (GUIDELINE) We recommend that sleep physicians consider prescription of oral appliances, rather than no treatment, for adult patients with obstructive sleep apnea who are intolerant of CPAP therapy or prefer alternate therapy. (STANDARD) We suggest that qualified dentists provide oversight— rather than no follow-up—of oral appliance therapy in adult patients with obstructive sleep apnea, to survey for dental-related side effects or occlusal changes and reduce their incidence. (GUIDELINE) We suggest that sleep physicians conduct follow-up sleep testing

Oral Effects and Early Implant Survival Results After Imatinib Discontinuation Therapy for Chronic Myelogenous Leukemia: A Case Report.

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 focused on a cohort of radiation naïve patients who had recurrent oral cavity cancer (recurrent OCC) to assess their outcomes with salvage multimodal therapy. A retrospective single institutional study was performed of patients with recurrent OCC. Disease recurrence and survival outcomes were assessed. Seventy-eight patients were analyzed. All patients had salvage surgery and intensity-modulated radiotherapy (IMRT) and 74% had chemotherapy. Five-year overall survival, recurrence-free survival, and locoregional control rates were 59%, 60%, and 74%, respectively. Outcomes of radiation naïve patients with recurrent OCC are fair, and seem similar with patients with locally advanced nonrecurrent OCC treated with multimodal therapy. © 2016 Wiley Periodicals, Inc.

The purpose of this study is to review the effects of low-level laser therapy (LLLT) in the prevention and treatment of cancer therapy-induced oral mucositis (OM). A systematic review and meta-analysis of randomised placebo-controlled trials of LLLT performed during chemotherapy or radiation therapy in head and neck cancer patients. We found 11 randomised placebo-controlled trials with a total of 415 patients; methodological quality was acceptable at 4.10 (SD ± 0.74) on the 5-point Jadad scale. The relative risk (RR) for developing OM was significantly (p = 0.02) reduced after LLLT compared with placebo LLLT (RR = 2.03 (95% CI, 1.11 to 3.69)). This preventive effect of LLLT improved to RR = 2.72 (95% CI, 1.98 to 3.74) when only trials with adequate doses above 1 J were included. For treatment of OM ulcers, the number of days with OM grade 2 or worse was significantly reduced after LLLT to 4.38 (95% CI, 3.35 to 5.40) days less than placebo LLLT. Oral mucositis severity was also reduced after LLLT with a standardised mean difference of 1.33 (95% CI, 0.68 to 1.98) over placebo LLLT. All studies registered possible side-effects, but they were not significantly different from placebo LLLT. There is consistent evidence from small high-quality studies that red and infrared LLLT can partly prevent development of cancer therapy-induced OM. LLLT also significantly reduced pain, severity and duration of symptoms in patients with cancer therapy-induced OM.

Current guidelines recommend that patients with Staphylococcus aureus bloodstream infection (SAB) are treated with long courses of intravenous antimicrobial therapy. This serves to avoid SAB-related complications such as relapses, local extension and distant metastatic foci. However, in certain clinical scenarios, the incidence of SAB-related complications is low. Patients with a low-risk for complications may thus benefit from an early switch to oral medication through earlier discharge and fewer complications of intravenous therapy. The major objective for the SABATO trial is to demonstrate that in patients with low-risk SAB a switch from intravenous to oral antimicrobial therapy (oral switch therapy, OST) is non-inferior to a conventional course of intravenous therapy (intravenous standard therapy, IST). The trial is designed as randomized, parallel-group, observer-blinded, clinical non-inferiority trial. The primary endpoint is the occurrence of a SAB-related complication (relapsing SAB, deep-seated infection, and attributable mortality) within 90 days. Secondary endpoints are the length of hospital stay; 14-day, 30-day, and 90-day mortality; and complications of intravenous therapy. Patients with SAB who have received 5 to 7 full days of adequate intravenous antimicrobial therapy are eligible. Main exclusion criteria are polymicrobial bloodstream infection, signs and symptoms of complicated SAB (deep-seated infection, hematogenous dissemination, septic shock, and prolonged bacteremia), the presence of a non-removable foreign body, and severe comorbidity. Patients will receive either OST or IST with a protocol-approved antimicrobial and are followed up for 90 days. Four hundred thirty patients will be randomized 1:1 in two study arms. Efficacy regarding incidence of SAB-related complications is tested sequentially with a non-inferiority margin of 10 and 5 percentage points. The SABATO trial assesses whether early oral switch therapy is safe and effective for

Minor oral surgery or dental extractions (oral or dental procedures) are widely performed and can be complicated by hazardous oral bleeding, especially in people with an inherited bleeding disorder such as haemophilia or Von Willebrand disease. The amount and severity of singular bleedings depend on disease-related factors, such as the severity of the haemophilia, both local and systemic patient factors (such as periodontal inflammation, vasculopathy or platelet dysfunction) and intervention-related factors (such as the type and number of teeth extracted or the dimension of the wound surface). Similar to local haemostatic measures and suturing, antifibrinolytic therapy is a cheap, safe and potentially effective treatment to prevent bleeding complications in individuals with bleeding disorders undergoing oral or dental procedures. However, a systematic review of trials reporting outcomes after oral surgery or a dental procedure in people with an inherited bleeding disorder, with or without, the use of antifibrinolytic agents has not been performed to date. The primary objective was to assess the efficacy of local or systemic use of antifibrinolytic agents to prevent bleeding complications in people with haemophilia or Von Willebrand disease undergoing oral or dental procedures. Secondary objectives were to assess if antifibrinolytic agents can replace or reduce the need for clotting factor concentrate therapy in people with haemophilia or Von Willebrand disease and to further establish the effects of these agents on bleeding in oral or dental procedures for each of these populations. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register, compiled from electronic database searches of the Cochrane Central Register of Controlled Trials (CENTRAL), of MEDLINE and from handsearching of journals and conference abstract books.

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

Oral mucositis is a common unpreventable complication associated with chemoradiation therapy. Shuanghua Baihe tablets have been approved by the Chinese Food and Drug Administration for treating recurrent oral mucosa ulceration. This study assessed whether Shuanghua Baihe tablets could prevent oral mucositis during chemoradiation therapy for locally advanced nasopharyngeal carcinoma. This multicenter, randomized, double-blind, placebo-controlled trial was conducted at 11 hospitals in China between January 22, 2014, and September 21, 2015. Eligible patients (N=240, 18-70 years old) with pathologically diagnosed locally advanced nasopharyngeal carcinoma were randomly assigned (computer-block randomization; 1:1) to receive Shuanghua Baihe tablets or a placebo (4 tablets, 3 times a day, for 7 weeks) at the initiation of chemoradiation therapy. Administration of Shuanghua Baihe tablets could be ended if grade 3 or higher oral mucositis developed and patients were unwilling to continue taking the drug. The primary endpoints were oral mucositis incidence and latency. The incidence of oral mucositis during this study was significantly lower in the Shuanghua Baihe group (85.0%; 95% confidence interval [CI], 78.6%-91.4%) than in the placebo group (96.6%; 95% CI, 93.4%-99.9%; P=.0028). The median latency period was 28 days in the Shuanghua Baihe group and 14 days in the placebo group (hazard ratio, 0.17; 95% CI, 0.12-0.23; P<.0001). Compared with placebo, Shuanghua Baihe tablets significantly reduced the oral mucositis severity scores recorded by the investigators (Oral Mucositis Score, 24.0 [range, 0.0-67.8] vs 57.5 [range, 0.0-98.0]; P<.0001), full-time nurses (Oral Assessment Guide score, 462.0 [range, 392.0-664.7] vs 520.4 [range, 392.0-714.0]; P<.0001), and patients (score for soreness of mouth and throat, 4.0 [range, 0-10] vs 6.0 [range, 0-10]; P<.0001). No serious adverse events were observed, and the incidence of mild or moderate gastrointestinal adverse events

Experiences gained in the management of oral mucosal lesions by CO2 and Nd:YAG laser therapy in an outpatient clinic treated over an 80-year period are described. Lasers have indications for use in dentistry for incision, excision, and coagulation of intraoral soft tissue. Advances in laser technology have provided delivery systems for site-specific delivery of laser energy with short interaction items on tissue to be ablated. This study retrospectively evaluates a series of clinical case studies. Sixty-four patients with a variety of benign oral soft tissue lesions were treated by laser excision. Thirty-five patients were treated by a pulsed fiberoptic delivered Nd:YAG contact laser, and 29 by a continuous free-beam CO2 non-contact laser. The largest group of lesions treated were leukoplakia (39 cases). Other lesions excised and biopsied were lichen planus, squamous papilloma, pyogenic granuloma, focal melanosis, nonhealing traumatic ulceration, hemangioma, and lymphangioma. All patients were followed postoperatively (mean 6.8 months, range 1-36 months). Laser excision was well tolerated by patients with no intraoperative or postoperative adverse effects. All patients healed postsurgically with no loss of function. CO2 and Nd:YAG lasers are successful surgical options when performing excision of benign intraoral lesions. Advantages of laser therapy include minimal postoperative pain, conservative site-specific minimally invasive surgeries, and elimination of need for sutures.

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{sup 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 primarymore » 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

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.

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 (p<0.05). Animals underwent PDZ-mediated aPDT showed complete remission of oral 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-) (p<0.05), 24 h and 7 days after treatment. In summary, the murine model developed here was able to mimic the infection and PDZ-mediated aPDT was effective to treat mice with oral candidiasis.

Conventional periodontal therapy aims at controlling supra- and subgingival biofilms. Although periodontal therapy was shown to improve periodontal health, it does not completely arrest the disease. Almost all subjects compliant with periodontal maintenance continue to experience progressive clinical attachment loss and a fraction of them loses teeth. An oral microbial transplant may be a new alternative for treating periodontitis (inspired by fecal transplant). First, it must be established that microbiomes of oral health and periodontitis are distinct. In that case, the health-associated microbiome could be introduced into the oral cavity of periodontitis patients. This relates to the goals of our study: (i) to assess if microbial communities of the entire oral cavity of subjects with periodontitis were different from or oral health contrasted by microbiotas of caries and edentulism patients; (ii) to test in vitro if safe concentration of sodium hypochlorite could be used for initial eradication of the original oral microbiota followed by a safe neutralization of the hypochlorite prior transplantation. Sixteen systemically healthy white adults with clinical signs of one of the following oral conditions were enrolled: periodontitis, established caries, edentulism, and oral health. Oral biofilm samples were collected from sub- and supra-gingival sites, and oral mucosae. DNA was extracted and 16S rRNA genes were amplified. Amplicons from the same patient were pooled, sequenced and quantified. Volunteer's oral plaque was treated with saline, 16 mM NaOCl and NaOCl neutralized by ascorbate buffer followed by plating on blood agar. Ordination plots of rRNA gene abundances revealed distinct groupings for the oral microbiomes of subjects with periodontitis, edentulism, or oral health. The oral microbiome in subjects with periodontitis showed the greatest diversity harboring 29 bacterial species at significantly higher abundance compared to subjects with the other

Outpatient oral therapy is infrequently used in pediatric low-risk febrile neutropenia (LRFN) as there is insufficient data regarding its equivalence as compared with parenteral therapy. This is a single institutional, randomized control trial in pediatric LRFN aged 2 to 15 years, in which 123 episodes in 88 patients were randomized to outpatient oral ofloxacin 7.5 mg/kg 12 hourly and amoxycillin-clavulanate 12.5 mg/kg 8 hourly or outpatient intravenous (IV) ceftriaxone 75 mg/kg and amikacin 15 mg/kg once daily after blood cultures. Out of 119 evaluable episodes, one-third were leukemia patients in maintenance and rest were solid tumors. Success was achieved in 55/61 (90.16%) and 54/58 (93.1%) in oral and IV arms, respectively, (P=0.56). There were 3 hospitalizations but no mortality. Median days to resolution of fever, absolute neutrophil count >500/mm(3) and antibiotic use were 3, 5, and 6 days in both arms. There were 5 blood culture isolates (3 gram-positive and 2 gram-negative bacteria). Failure of outpatient therapy was associated with perianal infections, bacteremia, febrile neutropenia onset before day 9 of chemotherapy in solid tumors and Vincristine, actinomycin-D, and cyclophosphamide chemotherapy for rhabdomyosarcoma. All gram-positive isolates were successes, whereas both gram-negative isolates were failures. Diarrhea in IV arm and Vincristine, actinomycin-D, and cyclophosphamide chemotherapy in the oral arm predicted failure in subgroup analysis. Outpatient therapy is efficacious and safe in pediatric LRFN. There was no difference in outcome in oral versus IV outpatient therapy. Amoxycillin-clavulanate and ofloxacin may be the oral regimen of choice.

Treatment of mild to moderate dehydration in children with oral rehydration therapy.

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.

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.

This article reviewed the relevant literature including published clinical trials and reviews on currently available oral hypoglycemic agents. Results showed that the benefits of glycemic control have been established through multiple clinical trials. Long-term control of blood glucose levels in type 1 and type 2 diabetic patients will decrease the incidence and prolong the time until progression of diabetic retinopathy, nephropathy, and neuropathy. Our increased understanding of the pathophysiology behind type 2 diabetes has led to the development of many new agents that are aimed at treating the underlying insulin resistance and relative insulinopenia. The sulfonylureas as a group have been used for many years and act by stimulating insulin secretion. They are useful alone or as combination therapy with insulin or another oral hypoglycemic agent. The biguanides act by decreasing hepatic glucose production and by increasing peripheral insulin sensitivity. The alpha-glucosidase inhibitors act nonsystemically by blocking the metabolism of digested polysaccharides and therefore lowering the amount of carbohydrate absorbed in a meal. Benzoic acid derivatives act in a manner similar to that of sulfonylureas by enhancing pancreatic insulin production. They offer a shorter duration of action, lowering the risk of hypoglycemia. The thiazolidinediones increase peripheral insulin sensitivity and are effective as both monotherapy and combination therapy. Oral hypoglycemic agents, when properly administered, are very effective in controlling type 2 diabetes and preventing long-term complications. PMID:10643211

Purpose 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. Methods 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. Results 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. Conclusion 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.

Hemostasis is a fundamental management issue post-operatively in minor oral surgical procedures. To ensure safety and therapeutic efficacy in patients, under oral anti coagulant therapy, is complicated by necessity for frequent determination of prothrombin time or international normalised ratio. The aim of the study was to determine whether early hemostasis achieved by using Hemcon Dental Dressing (HDD) will affect post-operative care and surgical healing outcome in minor oral surgical procedures. A total of 30 patients, aged 18 years to 90 years, except those allergic to seafood, who consented to participate, were enrolled into this study. Patients were required to have two or more surgical sites so that they would have both surgical and control sites. All patients taking Oral Anticoagulation Therapy (OAT) were included for treatment in the study without altering the anticoagulant regimens. Institutional Review Board approval was obtained for the same. The collected data was subjected to statistical analysis using unpaired t-test. All HDD surgically treated sites achieved hemostasis in 1.49 minutes and control wounds in 4.06 minutes (p < 0.001). Post-operative pain at HDD treated sites (1.87,1.27 on 1 st and 3 rd day respectively) was significantly lower than the control sites (4.0,1.87 on 1 st and 3 rd day respectively) p-value (0.001, 0.001 respectively). HDD treated oral surgery wounds achieved statistically significant improved healing both at 1 st and 3 rd post-operative days (p <0.0001). The HDD has been proven to be a clinically effective hemostatic dressing material that significantly shortens bleeding time following minor oral surgical procedures under local anaesthesia, including those patients taking OAT. Patients receiving the HDD had improved surgical wound healing as compared to controls.

To assess the impact of Doxazosin Oral Intake Therapy on urinary symptoms and pain in patients with indwelling ureteral stents Patients and Methods: A total of 239 patients with ureteral stone-related hydronephrosis who underwent a double-J stent insertion after ureteroscopic lithotripsy were enrolled. Patients were randomized to receive doxazosin cotrolled release 4 mg once daily for 4 weeks or matching placebo. Patients completed the brief-form Chinese version Ureteric Stent Symptom Questionnaire (USSQ) and quality of life (QoL) score 2 weeks and 4 weeks after stent placement and 4 weeks after stent withdrawal. The analgesic use was also recorded during the stenting period. Patients in Doxazosin Oral Intake Therapy group, in the first 2 weeks and second 2 weeks with the stent in situ, expressed significant lower daytime frequency (p=0.028 and p=0.038), nocturia (p=0.021 and p=0.008) and urgency (p=0.012 and p=0.014), respectively. Similarly, flank pain score, QoL score and analgesic use were also significant less in the stenting period. There was no significant difference in scores of urinary symptoms, pain and QoL during the post-stent period between two cohorts. Doxazosin Oral Intake Therapy reduced stent-related urinary symptoms, pain and the negative impact on QoL. Copyright© by the International Brazilian Journal of Urology.

Introduction Today, we frequently find patients taking oral anticoagulant therapy (OAT), a prophylaxis against the occurrence of thromboembolic events. An oral surgeon needs to know how to better manage such patients, in order to avoid hemorrhagic and thromboembolic complications. Materials and methods A group of 193 patients (119 men aged between 46 and 82 and 74 women aged between 54 and 76) undergoing OAT for more than 5 years were managed with a standardized management protocol and a 2-months follow-up. The aim of the present study was to apply a protocol, which could provide a safe intra- and postoperative management of patients on OAT. Results Among the 193 patients, only 2 had postoperative complications. Conclusions We think that the protocol used in the present study can be used for complete safety in the treatment of this type of patients. PMID:21771331

Illumination devices for uniform delivery of light to the oral cavity for photodynamic therapy

2011-10-01

To date, the lack of light delivery mechanisms to the oral cavity remains a barrier to the treatment of oral cancer with photodynamic therapy (PDT). The greatest impediment to medical practitioners is the current need to shield the normal tissues of the oral cavity, a costly and time-consuming procedure. In this research, we present the design of illumination devices to deliver light to the oral cavity for PDT, which will facilitate administration of PDT in the clinic. The goal for such an illumination device, as indicated by our clinical collaborators at Roswell Park Cancer Institute in Buffalo, NY, is to limit exposure of healthy tissue and produce an average irradiance of 100 mW/cm2 over the treatment field, with spatial non-uniformities below 10%. Furthermore, the size of the device must be compact to allow use in the oral cavity. Our research led to the design and fabrication of two devices producing spatial non-uniformities below 6% over a treatment area of 0.25 cm2 by design. One device consisted of an appropriately-sized reflector, inspired by solar concentrators, illuminated by a cylindrical diffusing fiber optimally located within the reflector; another was a solid lightpipe with a combination of optimized tapered and straight components.

Obstructive sleep apnoea (OSA) is associated with a variety of adverse health outcomes. Continuous positive airway pressure (CPAP) is considered first-line treatment for sleep apnoea patients, but there are few studies on oral health in patients with OSA who are using CPAP. This study aimed to estimate the prevalence of oral symptoms and interest in alternative treatments such as oral appliance (OA) therapy in CPAP users. A questionnaire was used to ascertain oral health including denture use, oral symptoms at present and since the start of CPAP, and interest in OA therapy. Relevant demographic and clinical data were collected from medical records. The 744 participants who completed the questionnaire had following characteristics (mean ± standard deviation): age (55.1 ± 12.9 years); apnoea-hypopnoea index (40.9 ± 23.2/h); body mass index (27.9 ± 5.2 kg/m(2) ) and length of CPAP usage (49.1 ± 30.7 months); halitosis (30.4%); and gingival bleeding (27.5%). Nearly half (44.6%) complained of dry mouth since beginning CPAP therapy. Patients with diabetes were older (57.8 ± 11.9 vs. 54.2 ± 12.8 years), had a higher rate of denture use (28.3 vs. 19.0%), more dental clinic visits (71.4 vs. 58.7%) and more oral symptoms (50.0 vs. 38.2%) than non-diabetes patients (p < 0.05). Thirty-eight per cent of subjects were interested in OA therapy. This study exhibited that almost 40% of CPAP users had oral symptoms. In particular, OSA patients with diabetes may be at high risk of oral disease. © 2015 John Wiley & Sons A/S and The Gerodontology Association. Published by John Wiley & Sons Ltd.

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

Oral combination therapy: repaglinide plus metformin for treatment of type 2 diabetes.

PubMed

Raskin, P

2008-12-01

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.

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

We made an open, noncomparative evaluation of ofloxacin, 400 mg orally bid for 10 days, in 98 subjects with community-acquired pneumonia or pathogen-confirmed bronchitis. Thirty-nine (40%) of the subjects were treated in the hospital and 59 (60%) were treated as outpatients. The mean age of those treated was 56.2 years; 73 (74%) of the subjects either were more than 60 years old or had a history of chronic obstructive pulmonary disease, or both. There were 95 organisms initially isolated in sputum, aspirate, or lavage fluid; all were susceptible to ofloxacin, and none acquired resistance during therapy. Haemophilus influenzae was the most common pathogen (19 isolates), followed by Streptococcus pneumoniae (18) and Staphylococcus aureus (10). Clinical responses included cure in 70 patients (71%), improvement in 26 (27%), and failure in two (2%). After 10 days of therapy, pathogens persisted in two cases; in one case, Streptococcus salivarius was isolated, though it remained susceptible to ofloxacin, and in the other, Klebsiella pneumoniae was accompanied by superinfection due to a resistant strain of Serratia marcescens. We included in this study three confirmed cases of atypical pneumonia successfully treated with ofloxacin, two of them due to Mycoplasma pneumonia and one to Legionella pneumophila. Ofloxacin was well tolerated. Our data indicate that ofloxacin is effective and safe as specific and empiric treatment for many lower respiratory tract infections.

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.

This study was a retrospective cohort analysis based on the ARNO database, a national record that tracks reimbursable prescription claims submitted from selected pharmacies to the Italian national health system. In total, 169,375 subjects, from an overall population of 4,040,624 were included in this study. The patients represented 12 different local health units. Each patient had at least one oral antidiabetic prescription claim (A10B ATC code). Patients were divided into four groups according to their treatment regimen during the recruitment period (1 January 2008-31 December 2008): MT, FDCT, LDCT and switching therapy. A timespan of 5 years was considered, from 4 years before to 1 year after the index date (i.e. date of the prescription selected in the recruitment period). A medication possession ratio (MPR) with a cut-off value of 80% was used to measure medication adherence. Descriptive statistics and multiple logistic regression were used to define the objectives, while P < 0.05 was considered to indicate significance. The median age of patients (n = 169,375, prevalence 4.2%) was 70 years [interquartile range (IQR) 17], and 49.1% were females. Considering the entire sample, the median MPRs for the treatment regimens were: MT, 0.73 (IQR 0.53; 43.9% compliant); FDCT, 1 (IQR 0.29, 68,5% compliant); and LDCT, 0.89 (IQR 0.33, 60.3% compliant). FDCT and LDCT were significantly correlated with MPR. Compliance was 48.9% in the prevalent patient cohort (i.e. patients prescribed oral antidiabetic therapy in both prerecruitment and recruitment periods); median MPRs for the treatment regimens were: MT, 0

Chronic recurrent aphthous stomatitis (CRAS) belongs to the group of chronic, inflammatory, ulcerative diseases of the oral mucosa. The aim of this study was to determine the effects of ozone on the morphofunctional peculiarities of the soft tissues in modeling chronic recurrent aphthous stomatitis. We performed experimental investigation for study of the morpho-functional state of tissues of the oral mucosa in CRAS with using of previously proposed and widely used modeling scheme with ovalbumin and aluminum hydroxide. Two groups of animals were formed (Dutch rabbits, males, aging three-month, weighting 2-2.4 kg). Group of 8 animals with obtained mucosal changes was our comparison group. Other group of 8 animals with obtained mucosal changes was treated by ozone therapy. Histological investigation has been performed. Microscopical examination of tissue had shown that ozone therapy reduces inflammation and edema and is useful in wound healing in soft tissue as disappearance of necrobiotic processes, epithelialization of aphthous defect, growth of akantotic bands, pronounced reducing of inflammatory cells and changing of cellular ratio (with of neutrophils part from 38.30±2.46% to 6.34±0.63%, eosinophils from 5.49±0.23% to 2.87±0.05%), restoration of the cellular layers of the epithelium, moderately pronounced sclerosis of the papillary layer of the lamina propria. Described results allow to conclude that correction of tissual changes in chronic recurrent aphthous stomatitis could be obtained with ozone therapy using.

To improve quality of life and prevent long-term risks in patients with inflammatory bowel diseases (IBDs: Crohn's disease, ulcerative colitis), it is essential to suppress inflammatory activity adequately. However, corticosteroids are only suitable for therapy of acute flares and the evidence for positive effects of immunosuppressive substances like azathioprine or 6-mercapropurine is mainly limited to maintenance of remission. In addition, only subgroups of patients benefit from biologicals targeting tumour necrosis factor α or α4β7 integrins. In summary, until now the disease activity is not sufficiently controlled in a relevant fraction of the patients with IBD. Thus, there is an urge for the development of new substances in the therapy of ulcerative colitis and Crohn's disease. Fortunately, new oral and parenteral substances are in the pipeline. This review will focus on oral substances, which have already passed phase II studies successfully at this stage. In this article, we summarize data regarding AJM300, phosphatidylcholine (LT-02), mongersen, ozanimod, filgotinib and tofacitinib. AJM300 and ozanimod were tested in patients with ulcerative colitis and target lymphocyte trafficking through inhibition of the α subunit of integrin, respectively binding to the sphingosine-1-phosphate receptor (subtypes 1 and 5) on lymphocytes. Mongersen was utilized in patients with Crohn's disease and accelerates the degradation of SMAD7 mRNA, which consequently strengthens the mainly anti-inflammatory signalling pathway of transforming growth factor β1. Various Janus kinase (JAK) inhibitors were developed, which inhibit the intracellular signalling pathway of cytokines. For example, the JAK1 blocker filgotinib was tested in Crohn's disease, whereas the JAK1/3 inhibitor tofacitinib was tested in clinical trials for both Crohn's disease and ulcerative colitis. A different therapeutic approach is the substitution of phosphatidylcholine (LT-02), which might recover the

In patients with type-2 diabetes receiving oral antidiabetic drugs (OADs), the addition of insulin is frequently required to achieve sufficient control over blood glucose levels. It is, however, difficult to predict if, when and in which patients insulin therapy will be needed. We aimed to identify patient related variables associated with the addition of basal insulin to oral therapy resulting in a basal supported oral therapy (BOT). DIVE (DIabetes Versorgungs-Evaluation) is a prospective, observational, multi-centre diabetes registry established in Germany in 2011. For the present explorative analysis, 31,008 patients with type-2 diabetes prescribed at least one OAD were included. Patients who had previously received insulin and those over 90 years old were excluded. The event of interest was defined as the initiation of BOT during the observational period. Cause-specific Cox proportional hazards models based on a competing risk framework were applied for risk quantification. Multivariable adjusted hazard ratios demonstrated that longer diabetes duration, higher BMI, poorer glycaemic control, documentation of any micro- or macrovascular comorbidity, the presence of concomitant non-antidiabetic pharmacotherapies, and greater numbers of prescribed OADs increased the likelihood of BOT initiation. On the other hand BOT initiation was less likely in patients with older age and female gender. Analysing the likelihood of OAD termination without initiation of BOT provided supportive evidence for the variables predictive of BOT initiation. Analysis of the DIVE registry has resulted in the identification of a number of factors that may be predictive for the initiation of BOT for type-2 diabetes patients initially prescribed one or more OADs. Poor glycaemic control, the presence of vascular comorbidities and concomitant medications, and a greater number of OADs were all detected to increase the risk of a switch to BOT. Female gender and younger age showed protective

Oral rehydration therapy and feeding for patients with diarrhea recommended by physicians who had attended the short course "Practical Approach to Common GI Problems" were compared with The Royal College of Pediatricians of Thailand Expert Committee on Gastrointestinal System's (RCPedT) Recommendations. A questionnaire was sent to physicians who had attended the short course. Physicians recommended a variety of oral rehydration solutions (ORS) which were different from RCPedT's recommendations. 42.6% of physicians recommended WHO/ORS, 54.1% recommended commercial ORS and 3.3% recommended any form of ORS. The other form of ORS, 59.0% of physicians recommended was carbonated drinks (nonphysiologic ORS) and 40.9% recommended home mixing of ORS. 55.7% of respondents recommended ORT for mild or moderate dehydration and 29.5% for mild or no dehydration only 14.8% of the physicians followed the guidelines. Although RCPedT WHO and American Academy of Pediatrics (AAP) Committee on Nutrition stated that vomiting was not a contraindication to successful use of ORT but vomiting was the most common reason (86.9%) given by respondents for failure of ORT and vomiting was the reason for starvation as well (11.5%). Early feeding of appropriate food 80.3% of respondents followed the guidelines but only 50.7% of respondents recommended breast feeding for children younger than 1 year old.

Oral mucositis is a common, debilitating complication of cancer patients undergoing chemotherapy and radiotherapy, occurring in about 40 percent cases. Mucositis may limit the patient's ability to tolerate chemotherapy or radiation therapy, and nutrition status is compromised. The aim of the study was to assess the effect of Indian turmeric powder with honey as a complementary therapy on treatment induced oral mucositis. In the study, quasi experimental non-equivalent control group pre test post-test design was used and non-probability purposive sampling technique was adopted to select 60 cancer patients with treatment induced oral mucositis, 30 each in experimental and control group. The independent 't' value for post-test 2 and 3 (post-test 2: 2.86 for WHO OMAS and 4.58 for MPJ OMAS, post test 2: 5.42 for WHO OMAS and 7.2 for MPJ OMAS; p < 0.05) were significant between experimental and control group. It is inferred that the application of Indian turmeric and honey on treatment-induced oral mucositis is effective.

: 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 < 0.001). The chance of postoperative hemorrhage for procedures with increased perioperative 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.

Purpose Isometric progressive resistance oropharyngeal (I-PRO) therapy improves swallowing function; however, current devices utilize a single sensor that provides limited information or are prohibitively expensive. This single-subject study presents results of I-PRO therapy, detraining, and maintenance using the 5-sensor Madison Oral Strengthening Therapeutic (MOST) device combined with upper esophageal sphincter (UES) dilatation. Methods A 56-year-old female nurse who was 27 months post stroke and subsequent to traditional behavioral interventions and UES dilatations presented limited to gastrostomy tube intake only and expectorating all saliva. She completed 8 weeks of I-PRO therapy, 5 weeks of detraining, and 9 weeks of I-PRO maintenance (reduced frequency) followed by a third UES dilatation post intervention. Data included diet inventory, lingual pressures (MOST), lingual volume (magnetic resonance imaging), postswallow residue (videofl uoroscopy), UES and pharyngeal pressures (high-resolution manometry), and quality of life (QOL). Results Findings after 8 weeks of I-PRO therapy were progression to general oral diet, 15 lb weight gain, increased isometric pressures (Δ >16 kPa) with transference to swallowing pressures, increased lingual volume (8.3%), reduced pharyngeal wall residue (P = .03), increased pharyngeal pressures (Δ > 43 mm Hg) and increased UES opening (nadir) pressures (Δ > 9 mm Hg) with improved temporopressure coordination across the pharynx, and improved QOL. After detraining, decreased isometric pressures and reduced UES opening were noted. After I-PRO maintenance, isometric anterior lingual pressures returned to levels noted after the 8 weeks of intervention. Conclusion I-PRO therapy, facilitated by the MOST device combined with instrumental UES dilatation, improved swallow safety, increased oropharyngeal intake, and facilitated UES opening while enriching QOL.

Studies have identified non-adherence as one of the major contributing factors to treatment failure in chronic myelogenous leukemia (CML) patients receiving imatinib. Published literature has demonstrated a unique role of oncology pharmacists, as part of a multidisciplinary team, in contributing to overall positive outcomes for patients. To evaluate the impact of an oncology pharmacist-managed oral anticancer therapy program on oral medication adherence in CML patients versus usual care. Electronic refill history and medical records of patients diagnosed with CML treated with oral tyrosine kinase inhibitors (TKIs) managed by oncology pharmacists during a 6-year period, were retrospectively reviewed. Imatinib adherence rate, as the primary endpoint, was compared with the rate for those in the usual care group within the same organization. The secondary endpoints were descriptive to characterize pharmacist interventions for all TKIs. A total of 56 patients including 45 who were treated with imatinib, were evaluated. The group managed by oncology pharmacists resulted in a higher percentage of imatinib adherence rate compared to usual care (88.6% vs 65.8%, p = 0.0046). A total of 3432 pharmacist encounters were reviewed, and 567 interventions of six categories including side effect monitoring/management (n = 95; 16.8%); drug interaction detection (n = 109; 19.2%); TKI dose adjustment (n = 82; 14.5%); laboratory monitoring (n = 200; 35.3%); non-CML related drug choice (n = 74; 13.1%); and copay assistance (n = 7; 1.2%), were documented. This resulted in a mean of 10.1 interventions per patient. Our oncology pharmacist-managed oral anticancer therapy program significantly improved TKI adherence rates in CML patients. We attribute the success of our program to consistent follow-up by utilizing routine phone, and secure email follow-ups, that allowed our oncology pharmacists to build a close and trustworthy relationship with patients and

Duration of oral tetracycline-class antibiotic therapy and use of topical retinoids for the treatment of acne among general practitioners (GP): A retrospective cohort study.

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.

Oxidative stress, increased lipid peroxidation, and impaired function of antioxidant system may contribute to the accelerated development of atherosclerosis in chronic renal failure patients during renal replacement therapy. The aim of the study was to investigate the influence of oral vitamin E (400 mg/day) in 14 patients who underwent continuous ambulatory peritoneal dialysis (CAPD) and effects of the vitamin E-coated dialyzer in 14 haemodialysis patients on several antioxidant biochemical parameters. Six-week treatment with oral vitamin E in CAPD patients and three-month treatment using vitamin E-coated dialyzer in haemodialysis patients led to the significant decrease of plasma malondialdehyde, to the increase of plasma vitamin E and to the increase of erythrocyte vitamin E in haemodialysis patients. No significant changes of erythrocyte antioxidant enzyme--superoxide dismutase, glutathione peroxidase and catalase were found during the both types of antioxidant therapy. At the end of the third month of haemodialysis study the significant increase of erythrocyte glutathione in haemodialysis patients was found, but that value was significantly lower as normal range. Six-week interruption of the administration of oral vitamin E in CAPD patients led to the significant decrease of erythrocyte superoxide dismutase and plasma vitamin E. Ten-week interruption of the use of vitamin E-coated dialyzer led to the significant increase of plasma malondialdehyde and to the decrease of plasma and erythrocyte vitamin E in haemodialysis patients, near to the values at the beginning of the study. Our study confirmed the beneficial effect of oral administration of vitamin E and the use of vitamin E-coated dialyzer against oxidative stress in CAPD and haemodialysis patients.

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.

It is difficult to evaluate the effect of drugs clinically used for idiopathic sudden sensorineural hearing loss, mainly because its underlying mechanism remains unknown. This study assessed the efficacy of hyperbaric oxygen therapy or ozone therapy in the treatment of idiopathic sudden sensorineural hearing loss, when either therapy was included with steroid treatment. A retrospective analysis examined 106 patients with idiopathic sudden sensorineural hearing loss seen between January 2010 and June 2012. Those with an identified etiology were excluded. The patients were divided into three treatment groups: oral steroid only (n=65), oral steroid+hyperbaric oxygen (n=26), and oral steroid+ozone (n=17). Treatment success was assessed using Siegel criteria and mean gains using pre- and post-treatment audiograms. The highest response rate to treatment was observed in the oral steroid+ozone therapy group (82.4%), followed by the oral steroid+hyperbaric oxygen (61.5%), and oral steroid groups (50.8%). There were no significant differences in the response to treatment between the oral steroid and oral steroid+hyperbaric oxygen groups (p<0.355). The oral steroid+ozone group showed a significantly higher response rate to treatment than the oral steroid group (p=0.019). There were no significant differences between the oral steroid+hyperbaric oxygen and oral steroid+ozone groups (p=0.146). The efficiency of steroid treatment in patients with severe hearing loss was low. It was statistically ascertained that adding hyperbaric oxygen or ozone therapy to the treatment contributed significantly to treatment success.

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.

Current management of oral cancer. A multidisciplinary approach.

Recent basic science discoveries have contributed to our understanding of the etiology of oral cancer and allowed us to consider innovative approaches to therapy. The authors evaluated and summarized current approaches to the management of oral cancer, emphasizing the multidisciplinary team approach to coordinate surgery, radiation therapy and chemotherapy. Current concepts in management, including complications of therapy, are described. State-of-the-art surgical techniques can spare patients with oral cancer from much of the morbidity and complications common in the past. The refinement of treatment strategies reduces complications and improves efficacy. Many exciting new clinical trials in the areas of gene therapy and immunomodulation are showing promise. Management of oral cancer has undergone radical change in the past 10 years and continues to evolve rapidly. Discoveries in molecular biology, diagnosis, surgery, radiation therapy and medical oncology have altered many traditional concepts and practices. General dental practitioners need to understand current treatment modalities for oral and pharyngeal cancers to determine to whom they should refer patients for the most appropriate treatment, and to make recommendations regarding complications associated with these cancers.

Thirty-two adults hospitalized with skin and skin structure infections received intravenous ofloxacin followed by oral ofloxacin. The standard treatment was 400 mg every 12 h. One patient with renal failure received 400 mg every 24 h. Serum ofloxacin levels were measured (1.5 h postdose and 1 h predose) during intravenous (32 patients) and oral (30 patients) therapy. Levels were assayed by high-pressure liquid chromatography (HPLC) and microbiological assay (MBA). Mean levels +/- standard deviation (in micrograms per milliliter) when measured by MBA after intravenous dosing were (postdose versus predose) 6.23 +/- 2.49 versus 2.42 +/- 1.56, and those after oral dosing were 6.17 +/- 3.25 versus 3.49 +/- 2.77. When measured by HPLC, mean levels +/- standard deviation after intravenous dosing were 5.81 +/- 2.08 versus 2.14 +/- 1.26 and those after oral dosing were 5.63 +/- 2.92 versus 3.41 +/- 2.98. There were no significant differences between levels achieved with oral or intravenous dosing when measured by either MBA or HPLC. Levels in serum did not correlate with side effects. The MICs for 50 and 90% of the 40 aerobic pathogens isolated from 21 patients were 0.5 and 2.0 micrograms/ml, respectively. Cure or improvement was achieved in 30 patients. Intravenous and oral administration of ofloxacin yielded similar levels in serum which were safe and effective in the therapy of skin infections in adult patients. PMID:1810189

Objective Iron deficiency is a common complication in patients with IBD and oral iron therapy is suggested to exacerbate IBD symptoms. We performed an open-labelled clinical trial to compare the effects of per oral (PO) versus intravenous (IV) iron replacement therapy (IRT). Design The study population included patients with Crohn's disease (CD; N=31), UC (N=22) and control subjects with iron deficiency (non-inflamed, NI=19). After randomisation, participants received iron sulfate (PO) or iron sucrose (IV) over 3 months. Clinical parameters, faecal bacterial communities and metabolomes were assessed before and after intervention. Results Both PO and IV treatments ameliorated iron deficiency, but higher ferritin levels were observed with IV. Changes in disease activity were independent of iron treatment types. Faecal samples in IBD were characterised by marked interindividual differences, lower phylotype richness and proportions of Clostridiales. Metabolite analysis also showed separation of both UC and CD from control anaemic participants. Major shifts in bacterial diversity occurred in approximately half of all participants after IRT, but patients with CD were most susceptible. Despite individual-specific changes in phylotypes due to IRT, PO treatment was associated with decreased abundances of operational taxonomic units assigned to the species Faecalibacterium prausnitzii, Ruminococcus bromii, Dorea sp. and Collinsella aerofaciens. Clear IV-specific and PO-specific fingerprints were evident at the level of metabolomes, with changes affecting cholesterol-derived host substrates. Conclusions Shifts in gut bacterial diversity and composition associated with iron treatment are pronounced in IBD participants. Despite similar clinical outcome, oral administration differentially affects bacterial phylotypes and faecal metabolites compared with IV therapy.

A major medical problem for patients undergoing electroconvulsive therapy (ECT) is the occurrence of postictal agitation (PIA). This phenomenon is associated with confusion and disorientation that can have severe clinical implications for the safety of the patient and health care professionals. Many different pharmacological strategies have been used to prevent PIA. We present data on 40 patients who suffered from PIA after a course of ECT and evaluate the prophylactic use of orally disintegrating olanzapine in the prevention of PIA in subsequent ECT treatments.

Over the last few decades, the incidence of oral cancer has gradually increased, due to the negative influence of environmental factors and also abnormalities within the genome. The main issues in oral cancer treatment consist in surpassing resistance and recurrence. However, continuous discovery of altered signaling pathways in these tumors provides valuable information for the identification of novel gene candidates targeted in personalized therapy. RNA interference (RNAi) is a natural mechanism that involves small interfering RNA (siRNA); this can be exploited in biomedical research by using natural or synthetic constructs for activation of the mechanism. Synthetic siRNA transcripts were developed as a versatile class of molecular tools that have a diverse range of programmable roles, being involved in the regulation of several biological processes, thereby providing the perspective of an alternative option to classical treatment. In this review, we summarize the latest information related to the application of siRNA in oral malignancy together with molecular aspects of the technology and also the perspective upon the delivery system. Also, the emergence of newer technologies such as clustered regularly interspaced short palindromic repeats/Cas9 or transcription activator-like effector nucleases in comparison with the RNAi approach is discussed in this paper.

Pathogenesis of vitiligo is believed to be multifactorial disease with a wide variety of therapeutic modalities. The aim of this work is to assess the efficacy of oral mini-pulse steroids (OMP) plus Nb-U.V.B in comparison to OMP alone and Nb-U.V.B alone in treating stable vitiligo. A prospective randomized controlled study including 45 patients categorized into three groups receiving therapy for 3 months; Group A received Nb-U.V.B plus OMP, Group B received OMP alone while Group C received Nb-U.V.B alone. Clinical assessment and PCR evaluation of bFGF, ICAM1, and ELISA for AMA were done. Patients receiving Nb-U.V.B plus OMP and using Nb-U.V.B alone gave statistically significant clinical response than those treated with OMP alone. Statistically significant rise of BFGF was noticed after treatment with Nb-U.V.B plus OMP and with Nb-U.V.B alone. Patients treated with OMP alone and with Nb-U.V.B alone showed statistically significant drop of ICAM-1 after therapy. NB-U.V.B plus OMP and Nb-U.V.B alone were found to be clinically superior over OMP alone in treating stable vitiligo patients, hence suggesting that adding OMP to Nb-U.V.B can maintain clinical and laboratory success for a longer period of time and with less relapse. © 2016 Wiley Periodicals, Inc.

Nano-pulse stimulation (NPS) is a novel technology to induce cancer apoptosis. In this study, based on the energy-dose effect of NPS, we designed a special NPS sequence (NPSS) with low field intensity. The effectiveness and mechanisms of NPSS on oral cancer therapy were evaluated by cell proliferation assays, microscopic investigation, JC-1 mitochondrial membrane potential assay, tumor inhibition assays, immunohistochemistry (IHC) assay, Ca 2+ , NOS and ROS detection assays, respectively. The results demonstrated that NPSS treatment significantly inhibited oral cancer growth in vitro and in vivo. Furthermore, we found that NPSS treatment induced an obviously apoptosis and mitochondrial membrane potential (ΔΨm) reduction in Cal-27 cells. Notably, further experiments revealed that the mechanisms of crosstalk signaling between NO, ROS and Ca 2+ involvement in NPSS treatment. In conclusion, this is a proof-of-concept study that provides a potential alternative strategy for developing and applying NPSS in oral cancer therapy. Copyright © 2018 Elsevier B.V.

Antivascular photodynamic therapy (PDT) suppresses tumor growth and prolonged the survival in solid tumor-bearing mice. The purpose of this study was to assess the efficacy of antivascular PDT using BPD-MA for treatment of oral and nasal tumors in 14 dogs. At 15 min after initiating intravenous infusion of 0.5 mg/kg benzoporphyrin derivative monoacid ring A, tumors were irradiated with laser light at 690 nm emitted by a diode laser. The 1-year survival rate of 7 dogs with oral tumors was 71%. The 1-year survival rate of 7 dogs with nasal tumors was 57%. Imaging of each tumor was performed by using angiographic computed tomography before and after each antivascular PDT. Contrast-enhanced tumors were observed before antivascular PDT, but these tumors were not enhanced with contrast medium following antivascular PDT. Antivascular PDT is suggested to be a promising method for dogs with oral and nasal tumors that cannot be effectively treated with current antitumor therapies.

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

This study compared the virulence of oral Candida species isolated from human immunodeficiency virus (HIV)-positive women with and without oral candidiasis. Candida species were isolated from 197 women, and their virulence attributes were measured. Of the 197 women, 117 (59.4%) carried Candida. Of these, 15 (12.8%) had symptoms of oral candidiasis. Among highly active antiretroviral therapy (HAART)-naive patients, 33% were diagnosed with oral candidiasis, whereas 5.9% were asymptomatic carriers (P < .01). C. albicans was the predominant species, with higher virulence attributes than non-albicans Candida. Women diagnosed with oral candidiasis had higher levels of Candida (P = .02) than asymptomatic carriers. There was no difference in the CD4 counts and the virulence attributes of Candida from both the groups. This study indicates that oral candidiasis is mainly caused by high counts of C. albicans and suggests the importance of therapies targeting Candida counts in the oral cavity even in patients on HAART to reduce the development of infections.

Background: The risk of stroke varies considerably across different groups of patients with atrial fibrillation (AF). Antithrombotic prophylaxis for stroke is associated with an increased risk of bleeding. We provide recommendations for antithrombotic treatment based on net clinical benefit for patients with AF at varying levels of stroke risk and in a number of common clinical scenarios. Methods: We used the methods described in the Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines article of this supplement. Results: For patients with nonrheumatic AF, including those with paroxysmal AF, who are (1) at low risk of stroke (eg, CHADS2 [congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, prior stroke or transient ischemic attack] score of 0), we suggest no therapy rather than antithrombotic therapy, and for patients choosing antithrombotic therapy, we suggest aspirin rather than oral anticoagulation or combination therapy with aspirin and clopidogrel; (2) at intermediate risk of stroke (eg, CHADS2 score of 1), we recommend oral anticoagulation rather than no therapy, and we suggest oral anticoagulation rather than aspirin or combination therapy with aspirin and clopidogrel; and (3) at high risk of stroke (eg, CHADS2 score of ≥ 2), we recommend oral anticoagulation rather than no therapy, aspirin, or combination therapy with aspirin and clopidogrel. Where we recommend or suggest in favor of oral anticoagulation, we suggest dabigatran 150 mg bid rather than adjusted-dose vitamin K antagonist therapy. Conclusions: Oral anticoagulation is the optimal choice of antithrombotic therapy for patients with AF at high risk of stroke (CHADS2 score of ≥ 2). At lower levels of stroke risk, antithrombotic treatment decisions will require a more individualized

Transition of Intravenous Treprostinil to Oral Therapy in a Patient with Functional Class IV Chronic Thromboembolic Pulmonary Hypertension.

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.

2016-08-01

Enhanced understanding of programmed death-ligand (PD-L) expression in oral cancer is important for establishing rational combinations of emerging immune checkpoint and molecular targeted therapies. We assessed PD-L and interferon (IFN) expression in immunogenic murine oral cancer-1 (MOC1) and poorly immunogenic MOC2 cell models after treatment with mammalian target of rapamycin (mTOR) and MEK1/2 small molecule inhibitors in vitro and in vivo. PD-L1 but not PD-L2 is expressed on MOC1 and 2 cells and is type I and II IFN-dependent. PD-L1 is differentially expressed on cancer and endothelial cells and infiltrating myeloid-derived suppressor cells, macrophages, and regulatory T cells (Tregs) in highly and poorly immunogenic tumors. PD-L1 expression is variably altered after treatment with inhibitors in vivo, with an imperfect relationship to alterations in IFN levels in the tumor microenvironment. PD-L1 expressed on cancer and infiltrating immune cells is variably altered by targeted therapies and may, in part, reflect changes in tumor IFN. © 2016 Wiley Periodicals, Inc.

This study was aimed at assessing the effectiveness and the importance of an oral hygiene (OH) protocol in patients undergoing radiation therapy and chemotherapy after prosthesis rehabilitation, in order to reduce or minimize oral complications. This study was carried out at the Department of Dental Science, at the University of Bari-Italy from December 2012 to December 2015 on 34 selected patients with primary oral cancer undergoing chemotherapy and radiotherapy after prosthesis rehabilitation. They were divided into 2 groups according to their age, sex and cancer therapy. Seventeen patients were assigned to the control group and seventeen in the experimental one. In the experimental group (Table 1), patients underwent an oral hygiene protocol whereas in the control group (Table 2) patients received the usual care provided within the clinical setting. All the patients gave written informed consent. It has been asked and obtained the authorisation from the Ethics Committee of the Dental Science and Surgery Department. Results show that in patients undergoing the oral hygiene protocol, the complications and the risks of infection and permanent dental problems have been minimized. Indeed, of the seventeen patients undergoing the OH protocol, 70% obtained positive results and were satisfied with the program outcome. The role of the health care providers is essential to educate patients to adhere to the prescribed treatments and reinforce their motivation in oral hygiene. The oral hygiene procedures prevent and ameliorate oral complications due to the radiation therapy and chemotherapy.

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.

Gaucher's disease (GD), a lysosomal storage disorder caused by mutations in the gene encoding glucocerebrosidase (GCD), is currently treated by enzyme replacement therapy (ERT) using recombinant GCD that is administered intravenously every 2 weeks. However, intravenous administration includes discomfort or pain and might cause local and systemic infections that may lead to low patient compliance. An orally administered drug has the potential to alleviate these problems. In this study, we describe the potential use of plant cells as a vehicle for the oral delivery of recombinant human GCD (prGCD) expressed in carrot cells. The in vitro results demonstrate that the plant cells protect the recombinant protein in the gastric fluids and may enable absorption into the blood. Feeding experiments, with rat and pig as model animals, using carrot cells containing prGCD, show that active recombinant prGCD was found in the digestive tract and blood system and reached both, liver and spleen, the target organs in GD. These results demonstrate that the oral administration of proteins encapsulated in plant cells is feasible. Specifically, carrot cells containing recombinant human prGCD can be used as an oral delivery system and are a feasible alternative to intravenous administration of ERT for GD. © 2015 Society for Experimental Biology, Association of Applied Biologists and John Wiley & Sons Ltd.

Cancer of the oral cavity is one of the most common malignancies worldwide. Although early diagnosis is relatively easy, presentation with advanced disease is not uncommon. The standard of care is primary surgical resection with or without postoperative adjuvant therapy. Improvements in surgical techniques combined with the routine use of postoperative radiation or chemoradiation therapy have resulted in improved survival. Successful treatment is predicated on multidisciplinary treatment strategies to maximize oncologic control and minimize impact of therapy on form and function. Prevention of oral cancer requires better education about lifestyle-related risk factors, and improved awareness and tools for early diagnosis. Copyright © 2015 Elsevier Inc. All rights reserved.

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.

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 bloodmore » 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.« less

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.

Oral monosaccharide therapies to reverse renal and muscle hyposialylation in a mouse model of GNE myopathy

GNE myopathy, previously termed hereditary inclusion body myopathy (HIBM), is an adult-onset neuromuscular disorder characterized by progressive muscle weakness. The disorder results from biallelic mutations in GNE, encoding UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase, the key enzyme of sialic acid synthesis. GNE myopathy, associated with impaired glycan sialylation, has no approved therapy. Here we test potential sialylation-increasing monosaccharides for their effectiveness in prophylaxis (at the embryonic and neonatal stages) and therapy (after the onset of symptoms) by evaluating renal and muscle hyposialylation in a knock-in mouse model (Gne p.M712T) of GNE myopathy. We demonstrate that oral mannosamine (ManN), but not sialic acid (Neu5Ac), mannose (Man), galactose (Gal), or glucosamine (GlcN), administered to pregnant female mice has a similar prophylactic effect on renal hyposialylation, pathology and neonatal survival of mutant offspring, as previously shown for N-acetylmannosamine (ManNAc) therapy. ManN may be converted to ManNAc by a direct, yet unknown, pathway, or may act through another mode of action. The other sugars (Man, Gal, GlcN) may either not cross the placental barrier (Neu5Ac) and/or may be able to directly increase sialylation. Because GNE myopathy patients will likely require treatment in adulthood after onset of symptoms, we also administered ManNAc (1 or 2 g/kg/day for 12 weeks), Neu5Ac (2g/kg/day for 12 weeks), or ManN (2g/kg/day for 6 weeks) in drinking water to 6 month old mutant Gne p.M712T mice. All three therapies markedly improved the muscle and renal hyposialylation, as evidenced by lectin histochemistry for overall sialylation status and immunoblotting of specific sialoproteins. These preclinical data strongly support further evaluation of oral ManNAc, Neu5Ac and ManN as therapy for GNE myopathy and conceivably for certain glomerular diseases with hyposialylation.

Posttympanostomy tube otorrhea (PTTO) results in significant health care cost and decreased satisfaction with care. The authors reviewed PTTO failing initial ototopical and/or oral antibiotic therapy and microbiology/susceptibility data from cultures. Case series with chart review. A community university satellite ambulatory clinic and the outpatient clinic of a children's hospital. Review of 202 patients with 228 discrete episodes of culture-positive otorrhea from January 2004 to January 2009. PTTO occurred an average of 13 months after tube placement. Median otorrhea duration was 21 days (mean, 42 days). A mean of 1.6 visits (range, 1-6) to the pediatric otolaryngology office was required for PTTO resolution. Ototopical therapy was reported used in 198 of 228 (87%) episodes of otorrhea prior to pediatric otolaryngology visit. Nearly 50% of patients were prescribed at least 1 or more courses of systemic antibiotics. Staphylococcus aureus accounted for 52% of the organisms cultured, with 57% methicillin-resistant S aureus (MRSA). S aureus resistance to clindamycin was high (49%) and resistance to levofloxacin was low (1.8%). MRSA was 68% clindamycin resistant, much higher than both ours and the children's hospital's clindamycin resistance rate of MRSA cultured from all other body sites. PTTO that presents as having failed ototopical and/or oral antibiotics most commonly consists of S aureus, Streptococcus pneumoniae, and Pseudomonas aeruginosa. MRSA is highly prevalent in this population. It is not necessary to culture PTTO that presents to an otolaryngology office, as resistance to levofloxacin was only 1.8%. It is unclear why the same fluoroquinolone ototopical therapy that failed initially is often successful in treating PTTO after otolaryngologist visit.

Canine atopic dermatitis (CAD) is a common allergic skin disease that has been treated with subcutaneously administered interferons (IFN). Recombinant feline IFN-ω (rFeIFN-ω) was reported to be efficacious for CAD. Whether dogs develop neutralizing antibodies against rFeIFN-ω during long-term treatment and whether orally administered IFNs are efficacious in CAD is unknown. The aim of this study was to evaluate the potential development of antibodies against rFeIFN-ω in atopic dogs and to compare subcutaneous and oral IFN therapy. Twenty-six atopic dogs were randomly assigned to two groups. The first group (n=15) received eight subcutaneous injections of rFeIFN-ω (Virbagen® omega, Virbac, Carros, France) over four months, the second group (n=11) received rFeIFN-ω daily orally. Concurrent medication was permitted, except systemically acting glucocorticoids and cyclosporin, which had to be withdrawn at least two weeks prior to the study. Serum samples for antibody detection were collected before and after the study. On days 0, 60 and 120 skin lesions and pruritus were evaluated using a validated lesion score (Canine Atopic Dermatitis Extent and Severity Index=CADESI) and a validated pruritus score. Concurrent medications were recorded. For every visit a total score, consisting of CADESI, pruritus score and medication score was created. For antibody detection an indirect ELISA, using Virbagen® omega as antigen, was performed. Comparison of pruritus scores, CADESI and total scores between days 0 and 120 showed improvement in both groups, however, significant improvement could only be detected in the oral group with CADESI and total scores (61%, P=0.04 and 36%, P=0.02 respectively). Serum antibodies against rFeIFN-ω could not be detected in any of the dogs. In this study antibody production could not be demonstrated. It suggests better efficacy with oral IFN administration, which should be further verified in larger, randomized, controlled studies. Copyright �

Oral contraceptives alone or in combination with antiandrogens are commonly used in the treatment for polycystic ovary syndrome (PCOS). We aimed to determine the effects of ethinyl estradiol/drospirenone (EE-DRSP) plus spironolactone therapy on inflammation and cardiometabolic risk in PCOS. Prospective cohort study. Twenty-three lean, normal glucose-tolerant patients with PCOS and 23 age- and body mass index (BMI)-matched healthy control women. Androgens, high-sensitivity C-reactive protein (hsCRP), homocysteine, lipids, fasting insulin, and glucose levels during a standard 75-g, 2-h oral glucose tolerance test were measured. Patients with PCOS were evaluated before and after receiving EE-DRSP (3 mg/30 μg) plus spironolactone (100 mg/day) for 6 months. Healthy controls were evaluated at baseline only. hsCRP, homocysteine, lipids, insulin and glucose levels were similar between patient and control groups at baseline. EE-DRSP plus spironolactone increased hsCRP and homocysteine levels in patients with PCOS (0.50 ± 0.28 vs 1.5 ± 1.3 mg/l, P < 0.05 and 13.1 ± 5.2 vs 17.6 ± 5.3 μm, P < 0.05, respectively). BMI, waist-to-hip ratio, LDL, HDL cholesterol and triglycerides, and glucose tolerance did not change. Modified Ferriman-Gallwey hirsutism scores, testosterone levels and free androgen index improved (9.1 ± 4.2 vs 6.2 ± 3.4, P = 0.001; 80.6 ± 31.1 47.8 ± 20.3 ng/dl, P < 0.05; and 10.5 ± 7.4 vs 1.1 ± 0.8, P < 0.001, respectively). EE-DRSP plus spironolactone therapy in 6 months improves androgen excess in lean PCOS women without any adverse effects on adiposity, glucose tolerance status or lipid profile. However, this combination increases hsCRP and homocysteine levels. © 2012 Blackwell Publishing Ltd.

Managing iron overload in patients with myelodysplastic syndromes with oral deferasirox therapy.

Patients with myelodysplastic syndromes (MDS) often require chronic RBC transfusions, which can lead to iron overload. Without adequate management, this may cause progressive damage to hepatic, endocrine, and cardiac organs, significantly affecting overall survival. Recent retrospective analyses have suggested that iron chelation provides a survival advantage in iron-overloaded patients with MDS who are given chelation therapy compared with those who are not. Nonetheless, it is evident that iron overload in many patients with MDS is not adequately managed. Clinical evaluation of the once-daily, oral iron chelator deferasirox in MDS populations has indicated that it provides dose-dependent reductions in body iron burden and is generally well tolerated, with a manageable safety profile in adult and pediatric patients. The most common treatment-related adverse events (AEs) included transient, mild-to-moderate gastrointestinal disturbances and skin rash, which rarely required drug discontinuation and resolved spontaneously in most cases. Adequate management of AEs and practical approaches such as patient education and counseling are necessary to ensure that patients remain compliant with therapy. Regular monitoring of serum ferritin levels is key to identifying patients who require iron chelation therapy, and to ensure maintenance of iron levels below the critical level of 1,000 microg/l. The flexible dosing regimen of deferasirox allows dose adjustments to be made in response to trends in serum ferritin, to changes in a patient's transfusional iron intake, and to the objectives of treatment, allowing the full benefit of transfusion therapy without the risks associated with iron overload.

Patients with severe oral lichen planus refractory to standard topical treatment currently have limited options of therapy suitable for long-term use. Oral alitretinoin (9-cis retinoic acid) was never systematically investigated in clinical trials, although case reports suggest its possible efficacy. To assess the efficacy and safety of oral alitretinoin taken at 30 mg once daily for up to 24 weeks in the treatment of severe oral lichen planus refractory to standard topical therapy. We conducted a prospective open-label single arm pilot study to test the efficacy and safety of 30 mg oral alitretinoin once daily for up to 24 weeks in severe oral lichen planus. Ten patients were included in the study. Primary end point was reduction in signs and symptoms measured by the Escudier severity score. Secondary parameters included pain and quality of life scores. Safety parameters were assessed during a follow-up period of 5 weeks. A substantial response at the end of treatment, i.e. >50% reduction in disease severity measured by the Escudier severity score, was apparent in 40% of patients. Therapy was well tolerated. Adverse events were mild and included headache, mucocutaneous dryness, musculoskeletal pain, increased thyroid-stimulating hormone and dyslipidaemia. Alitretinoin given at 30 mg daily reduced disease severity of severe oral lichen planus in a substantial proportion of patients refractory to standard treatment, was well tolerated and may thus represent one therapeutic option for this special group of patients. © 2015 European Academy of Dermatology and Venereology.

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.

2017-01-01

This study aimed to estimate the risk of bleeding following minor oral surgical procedures and uninterrupted aspirin therapy in high-risk patients or patients with existing chronic diseases compared to patients who did not use aspirin during minor oral surgery at a public hospital. This retrospective cohort study analyzed the data of 2912 patients, aged 20 years or older, who underwent 5251 minor oral surgical procedures at a district hospital in Thailand. The aspirin group was comprised of patients continuing aspirin therapy during oral surgery. The non-aspirin group (reference) included all those who did not use aspirin during surgery. Immediate and late-onset bleeding was evaluated in each procedure. The risk ratio of bleeding was estimated using a multilevel Poisson regression. The overall cumulative incidence of immediate bleeding was 1.3% of total procedures. No late-onset bleeding was found. A significantly greater incidence of bleeding was found in the aspirin group (5.8% of procedures, p<0.001). After adjusting for covariates, a multilevel Poisson regression model estimated that the bleeding risk in the aspirin group was 4.5 times higher than that of the non-aspirin group (95% confidence interval, 2.0 to 10.0; p<0.001). However, all bleeding events were controlled by simple hemostatic measures. High-risk patients or patients with existing chronic diseases who continued aspirin therapy following minor oral surgery were at a higher risk of hemorrhage than general patients who had not used aspirin. Nonetheless, bleeding complications were not life-threatening and could be promptly managed by simple hemostatic measures. The procedures could therefore be provided with an awareness of increased bleeding risk, prepared hemostatic measures, and postoperative monitoring, without the need for discontinuing aspirin, which could lead to more serious complications.

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.

To compare effectiveness of oral therapy with reduced nicotinamide adenine dinucleotide (NADH) to conventional modalities of treatment in patients with chronic fatigue syndrome (CFS). CFS is a potentially disabling condition of unknown etiology. Although its clinical presentation is associated to a myriad of symptoms, fatigue is a universal and essential finding for its diagnosis. No therapeutic regimen has proven effective for this condition. A total of 31 patients fulfilling the Centers for Disease Control criteria for CFS, were randomly assigned to either NADH or nutritional supplements and psychological therapy for 24 months. A thorough medical history, physical examination and completion of a questionnaire on the severity of fatigue and other symptoms were performed each trimester of therapy. In addition, all of them underwent evaluation in terms of immunological parameters and viral antibody titers. Statistical analysis was applied to the demographic data, as well as to symptoms scores at baseline and at each trimester of therapy. The twelve patients who received NADH had a dramatic and statistically significant reduction of the mean symptom score in the first trimester (p < 0.001). However, symptom scores in the subsequent trimesters of therapy were similar in both treatment groups. Elevated IgG and Ig E antibody levels were found in a significant number of patients. Observed effectiveness of NADH over conventional treatment in the first trimester of the trial and the trend of improvement of that modality in the subsequent trimesters should be further assessed in a larger patient sample.

Objective The National Cancer Center Network recommends starting radiation therapy within 6 weeks after surgery for oral cavity squamous cell carcinoma (OCSCC), but there is limited evidence of the importance of the total time from surgery to completion of radiation therapy (package time). We set out to determine if there was an association between package time and survival in OCSCC and to evaluate the impact of treatment location on outcomes. Study Design Retrospective cohort study. Setting Tertiary academic medical center. Subjects and Methods We reviewed the records of patients with OCSCC who completed postoperative radiation therapy at an academic medical center from 2008 to 2016. The primary endpoints were overall survival and recurrence-free survival. Statistical analysis included χ 2 tests and Cox proportional hazards regressions. Results We identified 132 patients with an average package time of 12.6 weeks. On multivariate analysis, package time >11 weeks was independently associated with decreased overall survival (hazard ratio, 6.68; 95% CI, 1.42-31.44) and recurrence-free survival (hazard ratio, 2.94; 95% CI, 1.20-7.18). Patients who received radiation therapy at outside facilities were more likely to have treatment delays (90.2% vs 62.9%, P = .001). Conclusions Prolonged package times are associated with decreased overall and recurrence-free survival among patients with OCSCC. Patients who received radiation therapy at outside facilities are more likely to have prolonged package times.

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.

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.

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

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, p<0.001) while more patients switched to fingolimod than any other therapy (42.3% of switches). Patients switched to fingolimod due to convenience. Patients treated with fingolimod were less likely to discontinue treatment compared with other therapies (p<0.001). Female sex, country of residence, younger age, a high Expanded Disability Status Scale score and relapse activity were all independently associated with higher rates of treatment 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.

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 and betel quid in >40 years.

The treatment of hospitalized patients with community-acquired pneumonia (CAP) has traditional been with intravenous antibiotics. More recently, the focus of this antibiotic therapy has been empiric and based on the most likely pathogens in a given patient. The concept of when and how to approach the patient for conversion to oral therapy, known as switch therapy, is now the focus of controversy. Recently, several studies have emerged from the literature that shed some light on the subject of switch therapy for CAP. Although the data are limited at this time, it seems clear that switching to oral antibiotics in selected low-risk patients may be feasible and safe. In this article, we focus on the problem and help formulate a practical approach to switching patients from intravenous antibiotics to oral therapy for CAP.

The risk of excessive bleeding prompts physicians to stop low-dose long-term aspirin regimens before surgery, which puts the patient at risk from adverse thrombotic events. We hypothesize that most minor oral surgical procedures can be carried out safely without stopping low-dose aspirin. All minor oral surgery patients at our hospital (Madan Dental Hospital, Ahmedabad, India) from May 2002 to May 2003, who were also on long-term low-dose aspirin therapy regimens (acetylsalicylic acid 75 mg to 100 mg/day), were included. Investigation of bleeding time and platelet count was performed. If within normal limits, aspirin was not stopped before surgery. Patients were operated under local anesthesia on an outpatient basis. All wounds were sutured and followed up at 24, 48, and 72 hours, 1 week, and 2 weeks after the procedure. The study included 51 patients (32 males, 19 females), ranging in age from 45 to 70 years. Preoperative values were within normal limits for all patients. Aspirin was not stopped for a single patient. There was no excessive intraoperative bleeding in all cases except 1; there was no postoperative bleeding in all cases. We conclude that most minor oral surgery procedures can be carried out safely without stopping long-term low-dose aspirin regimen.

External and interstitial radiation therapy of carcinoma of the oral tongue. A review of 32 years' experience.

In 204 patients with squamous cell carcinoma of the oral tongue treated with radiation therapy, the most significant prognostic factors appeared to be the presence of neck lymph node metastasis on presentation and the status of the disease three months after treatment. The most common site of failure was the primary lesion, either alone or with neck disease. External irradiation alone was seldom successful. Use of peroral cone irradiation or interstitial implants, either alone or in combination with external irradiation, achieved good local control in early lesions. When the primary tumor was uncontrolled by radiation therapy, salvage with surgery was rare. When failure occurred in the neck alone, radical neck dissection was successful in the majority of cases.

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

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.

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.

Considerations for long-term anticoagulant therapy in patients with venous thromboembolism in the novel oral anticoagulant era.

PubMed

Toth, Peter P

2016-01-01

Patients who have had a venous thromboembolic event are generally advised to receive anticoagulant treatment for 3 months or longer to prevent a recurrent episode. Current guidelines recommend initial heparin and an oral vitamin K antagonist (VKA) for long-term anticoagulation. However, because of the well-described disadvantages of VKAs, including extensive food and drug interactions and the need for regular anticoagulation monitoring, novel oral anticoagulants (NOACs) have become an attractive option in recent years. These agents are given at fixed doses and do not require routine coagulation-time monitoring. The NOACs are discussed in this review with regard to the needs of patients on long-term anticoagulation. Current guidelines from Europe and North America that refer to the treatment of deep vein thrombosis and/or pulmonary embolism are included, as well as published randomized Phase III clinical trials of NOACs. PubMed searches were used for sourcing case studies of long-term anticoagulant treatment, and results were filtered for human application and screened for relevance. NOAC-based therapy showed a similar efficacy and safety profile to heparins/VKAs but without the need for regular anticoagulation monitoring or dietary adjustments, and can be taken as a fixed-dose regimen once or twice daily. This represents a significant step forward in facilitating the management of long-term anticoagulation therapy. Furthermore, in the EINSTEIN studies, improved patient satisfaction was documented with the NOAC rivaroxaban, which may result in better adherence to therapy and an overall reduction in the incidence of recurrent venous thromboembolism.

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.

Advances in Oral Appliances for Obstructive Sleep Apnea.

PubMed

Jacobowitz, Ofer

2017-01-01

Oral appliances that advance the mandible are widely used as alternatives to positive airway pressure (PAP) devices or as primary therapy for obstructive sleep apnea (OSA) in adults. Although PAP is more efficacious at lowering the polysomnographic indices of OSA, the clinical effectiveness of PAP and oral appliances is similar, and patients are more likely to adhere to oral appliance therapy than to PAP treatment. Clinical examination is used to determine the candidacy of oral appliances and to select a particular appliance for a given patient. Endoscopic examination of the pharynx may be used to help assess the potential for efficacy. Otherwise, if available, titration of mandibular protrusion during sleep may be performed prior to appliance production in order to assess efficacy. Once a patient is fitted with a titratable oral appliance, further advancement is usually performed at home to resolve the clinical symptoms and signs of OSA. Clinical follow-up is needed to assess the outcome, side effects, and adherence, as the long-term adherence rate is approximately 50%. Recent advances in oral appliance therapy include the development of embedded temperature sensors for adherence monitoring and the production of thinner, lighter appliances via 3D printing techniques. © 2017 S.

Background Patients with partial adhesive small-bowel obstruction are usually managed conservatively, receiving intravenous hydration and nothing by mouth. Previous studies have suggested that this approach is associated with longer hospital stays and an increased risk of delayed surgery. We conducted a randomized controlled trial to see if combining standard conservative treatment with oral administration of a laxative, a digestant and a defoaming agent would reduce the frequency of subsequent surgical intervention and reduce the length of hospital stay. Methods We identified 144 consecutive patients admitted between February 2000 and July 2001 with adhesive partial small-bowel obstruction and randomly assigned 128 who met the inclusion criteria to either the control group (intravenous hydration, nasogastric-tube decompression and nothing by mouth) or the intervention group (intravenous hydration, nasogastric-tube decompression and oral therapy with magnesium oxide, Lactobacillus acidophilus and simethicone). The primary outcome measures were the number of patients whose obstruction was successfully treated without surgery and the length of hospital stay. We also monitored rates of complications and recurring obstructions. Results Of the 128 patients, 63 were in the control group and 65 in the intervention group; the mean ages were 54.4 (standard deviation [SD] 15.9) years and 53.9 (SD 16.3) years respectively. Most of the patients were male. More patients in the intervention group than in the control group had successful treatment without surgery (59 [91%] v. 48 [76%], p = 0.03; relative risk 1.19, 95% confidence interval 1.03–1.40). The mean hospital stay was significantly longer among patients in the control group than among those in the intervention group (4.2 [SD 2.7] v. 1.0 [SD 0.7] days, p < 0.001). The complication and recurrence rates did not differ significantly between the 2 groups. Interpretation Oral therapy with magnesium oxide, L. acidophilus and

Men who receive bone-targeted therapy for metastatic prostate cancer are at increased risk of osteonecrosis of the jaw (ONJ). Development of ONJ has been associated with the administration of bone-targeted therapies in association with other risk factors. ONJ can be distressing for a patient because it can cause pain, risk of jaw fracture, body image disturbance, difficultly eating, and difficulty maintaining good oral hygiene. The aim of this article is to report results of an audit of prior assessment by oral and maxillofacial surgeons (OMFS) before initiation of bone-targeted therapies and whether it may reduce the risk of ONJ in patients receiving bone-targeted therapies for advanced cancers.

Oral rehydration therapy (ORT) has been shown to be useful in decreasing mortality, reducing treatment costs and diminishing the frequency of complications in children under the age of five with acute diarrhea. The current concept of ORT includes not only the increase in the intake of fluids and the administering of oral solution in order to prevent or treat dehydration, but also the continuance of everyday feeding, the teaching of the child's mother to detect signs of dehydration and other alarming changes, as well as the non-administering of medication, especially those considered as anti-diarrheal or anti-vomiting, and limiting the use of antimicrobials, only to be used in special cases. The theoretical know-how of these concepts has been seen to be insufficient in order to increase the use of community-wide Oral Rehydration Therapy, being this the main purpose for the establishment of the Oral Rehydration Ward in teaching hospitals of second and third level, where the majority of its' personnel must come into contact with and share the responsibility of treating children with diarrhea. Within these wards students obtain information, ability and assurance in the effective actual management of children with diarrhea, including the correction of the state of dehydration through the administering of oral solutions. Another complementary benefit from the coming about of this ward is the decrease in the need to hospitalize the majority of the patient with diarrhea therefore reducing costs and any related complications.

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 < 0.001). Baseline dopHbA1c was positively associated with HbA1c reduction from baseline to week 24 (β coefficient 0.883, 95% CI 0.811 to 0.955, p < 0.001), and the association remained significant after adjustment for confounders. In T2D patients with an HbA1c ≧7%, a higher baseline dopHbA1c was associated with a greater HbA1c reduction after shifting to vildagliptin-based dual oral therapy. Copyright © 2018 Elsevier B.V.

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.

Combination therapy with S-1, superselective intra-arterial infusion of 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 gingiva (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 IIbor 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.

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.

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.

Clinical implications of epigenetic regulation in oral cancer.

Oral cancer is a high incidence cancer which is of major public health concern in India being the most common cancer in males and fifth most common cancer in females in India, contributing to 26% of the global oral cancer burden. The major risk factors of oral cancer are tobacco, alcohol and high risk Human Papilloma Virus type 16/18. However, only 3-12% of the high risk individuals with dysplasia develop oral cancer. Thus, individual genomic variants representing the genomic constitution and epigenetic alterations play a critical role in the development of oral cancer. Extensive epigenetic studies on the molecular lesions including oncogenes, tumor suppressor genes, genes associated with apoptosis, DNA damage repair have been reported. The current review highlights epigenetic regulation with a focus on molecular biomarkers and epidrug therapy in oral cancer. Epigenetic regulation by hypermethylation, histone modifications and specific microRNAs are often associated with early events and advanced stages in oral cancer, and thus indicate epidrug therapy for intervention. The presence of epigenetic marks in oral lesions, cancers and tumor associated mucosa emphasizes indications as biomarkers and epidrugs with therapeutic potential for better patient management.

The development of dental therapy in the U.S. grew from a desire to find a workforce solution for increasing access to oral health care. Worldwide, the research that supports the value of dental therapy is considerable. Introduction of educational programs in the U.S. drew on the experiences of programs in New Zealand, Australia, Canada, and the United Kingdom, with Alaska tribal communities introducing dental health aide therapists in 2003 and Minnesota authorizing dental therapy in 2009. Currently, two additional states have authorized dental therapy, and two additional tribal communities are pursuing the use of dental therapists. In all cases, the care provided by dental therapists is focused on communities and populations who experience oral health care disparities and have historically had difficulties in accessing care. This article examines the development and implementation of the dental therapy profession in the U.S. An in-depth look at dental therapy programs in Minnesota and the practice of dental therapy in Minnesota provides insight into the early implementation of this emerging profession. Initial results indicate that the addition of dental therapists to the oral health care team is increasing access to quality oral health care for underserved populations. As evidence of dental therapy's success continues to grow, mid-level dental workforce legislation is likely to be introduced by oral health advocates in other states. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

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 <50 %. These groups of patients will have their illness perceptions, anticoagulation specific quality of life and beliefs about medications compared. Those patients in the time in therapeutic range <50 % group, will be then be invited to switch to a novel oral anticoagulant, as per local guidance. Those patients, who do switch, will then be followed longitudinally and have their adherence, illness perceptions, anticoagulation specific quality of life and 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.

Antibiotic therapy has reached its limits with regard to antimicrobial resistance, and new therapeutic measures utilizing natural phytochemicals are currently a focus of research. Hence, this systematic review provides a critical presentation of the antimicrobial effects of various medicinal herbs against in vitro, ex vivo, and in situ formed multispecies oral biofilms. Searches were performed in three English databases (PubMed, EMBASE, CAMbase) and the electronic archives of five German journals from the times of their establishment until October 10th, 2014, with the search terms “(plant extracts OR herbal extracts OR plant OR herb) AND (oral biofilm OR dental biofilm OR dental plaque OR oral disease OR dental disease).” The pooled data were assessed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). Initially, 1848 articles were identified, out of which 585 full-text articles were screened, 149 articles were reevaluated for eligibility and finally, 14 articles met all inclusion criteria. The data of 14 reports disclosed enhanced antiadhesive and antibiofilm activity by the plant extracts obtained from Vitis vinifera, Pinus spp., Coffea canephora, Camellia sinensis, Vaccinium macrocarpon, Galla chinensis, Caesalpinia ferrea Martius, Psidium cattleianum, representative Brazilian plants and manuka honey. Overall, a positive correlation was revealed between herb-based therapies and elimination rates of all types of multispecies oral biofilms. In that context, integrating or even replacing conventional dental therapy protocols with herbal-inspired treatments can allow effective antimicrobial control of oral biofilms and thus, dental diseases.

The aim of this study was to introduce an oral rehydration therapy with OS-1 for advanced and recurrent gastrointestinal cancer patients to reduce a hospital stay as well as having a good QOL. We targeted 10 advanced cancer patients. In this study, We recommended the OS-1 drinking amount to be 500 mL to 1, 000 mL whenever the following symptoms were observed:(1) the patient's meal consumption was decreased in half, (2) the volume of urine was decreased, and (3) the frequency of urine was decreased. Nine out of 10 patients were able to drink OS-1 in the range of 500 mL to 1, 000 mL. Most of the patients were taking the chemotherapy along with OS-1 therapy. We confirmed two distinct cases: The patients with OS- 1 short-term drinker at the time of appetite fall because of chemotherapy. Another case was the patients with OS-1 longterm drinkers due to the end of life stage which decreased in meal frequency. ORT with OS-1 may contribute to improve QOL of the terminal patient with chemotherapy.

Salivary Cytokine Levels and Oral Mucositis in Head and Neck Cancer Patients Treated With Chemotherapy and Radiation Therapy

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

Bossi, Paolo, E-mail: Paolo.bossi@istitutotumori.mi.it; Bergamini, Cristiana; Miceli, Rosalba

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, especiallymore » 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.« less

Boron microlocalization in oral mucosal tissue: implications for boron neutron capture therapy

Clinical studies of the treatment of glioma and cutaneous melanoma using boron neutron capture therapy (BNCT) are currently taking place in the USA, Europe and Japan. New BNCT clinical facilities are under construction in Finland, Sweden, England and California. The observation of transient acute effects in the oral mucosa of a number of glioma patients involved in the American clinical trials, suggests that radiation damage of the oral mucosa could be a potential complication in future BNCT clinical protocols, involving higher doses and larger irradiation field sizes. The present investigation is the first to use a high resolution surface analytical technique to relate the microdistribution of boron-10 (10B) in the oral mucosa to the biological effectiveness of the 10B(n,α)7Li neutron capture reaction in this tissue. The two boron delivery agents used clinically in Europe/Japan and the USA, borocaptate sodium (BSH) and p-boronophenylalanine (BPA), respectively, were evaluated using a rat ventral tongue model. 10B concentrations in various regions of the tongue mucosa were estimated using ion microscopy. In the epithelium, levels of 10B were appreciably lower after the administration of BSH than was the case after BPA. The epithelium:blood 10B partition ratios were 0.2:1 and 1:1 for BSH and BPA respectively. The 10B content of the lamina propria was higher than that measured in the epithelium for both BSH and BPA. The difference was most marked for BSH, where 10B levels were a factor of six higher in the lamina propria than in the epithelium. The concentration of 10B was also measured in blood vessel walls where relatively low levels of accumulation of BSH, as compared with BPA, was demonstrated in blood vessel endothelial cells and muscle. Vessel wall:blood 10B partition ratios were 0.3:1 and 0.9:1 for BSH and BPA respectively. Evaluation of tongue mucosal response (ulceration) to BNC irradiation indicated a considerably reduced radiation sensitivity using BSH as

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).

Guidelines recommend use of the oral route whenever possible to treat or prevent hypokalemia. Although a myriad of papers have been published regarding intravenous to oral (IV to PO) therapy conversion programs and about clinical pharmacy services provided in hospitals, little is known on the role of hospital pharmacists in promoting the oral route for potassium administration. The aim of this work was to describe the frequency of interventions related to IV to PO potassium therapy conversions performed by hospital pharmacists. Setting French hospitals recording pharmacist's interventions on the website tool of the French Society of Clinical Pharmacy. From the pharmacist's interventions (PI) dataset recorded we extracted all interventions related to potassium IV to PO conversion. We assessed the acceptance rate of these PI by prescribers. Additional free text information in the dataset was analysed. IV to PO potassium therapy conversions related to potassium chloride. From January 2007 to December 2010, 87 hospitals recorded 1,868 PIs concerning IV to PO therapy conversion. Among these, 16 (<1 %) concerned potassium chloride. They were recorded by four hospitals (4.6 %) with respectively 12, 2, 1 and 1 PIs. Six PIs were accepted by physicians and the prescriptions were modified. PIs to promote the administration of potassium by the oral route are extremely rare. Our results and scarce previously published data reveal that this field of practice remains almost unexplored. These findings highlight an important gap in the field of intravenous to oral therapy programs. This situation must be regarded as unsatisfactory and should lead to setting up more education and research programs.

Transgenic tomato plants were constructed with an empty vector (EV) or a vector expressing an apoA-I mimetic peptide, 6F. EV or 6F tomatoes were harvested, lyophilized, ground into powder, added to Western diet (WD) at 2.2% by weight, and fed to LDL receptor-null (LDLR−/−) mice at 45 mg/kg/day 6F. After 13 weeks, the percent of the aorta with lesions was 4.1 ± 4%, 3.3 ± 2.4%, and 1.9 ± 1.4% for WD, WD + EV, and WD + 6F, respectively (WD + 6F vs. WD, P = 0.0134; WD + 6F vs. WD + EV, P = 0.0386; WD + EV vs. WD, not significant). While body weight did not differ, plasma serum amyloid A (SAA), total cholesterol, triglycerides, and lysophosphatidic acid (LPA) levels were less in WD + 6F mice; P < 0.0295. HDL cholesterol and paroxonase-1 activity (PON) were higher in WD + 6F mice (P = 0.0055 and P = 0.0254, respectively), but not in WD + EV mice. Plasma SAA, total cholesterol, triglycerides, LPA, and 15-hydroxyeicosatetraenoic acid (HETE) levels positively correlated with lesions (P < 0.0001); HDL cholesterol and PON were inversely correlated (P < 0.0001). After feeding WD + 6F: i) intact 6F was detected in small intestine (but not in plasma); ii) small intestine LPA was decreased compared with WD + EV (P < 0.0469); and iii) small intestine LPA 18:2 positively correlated with the percent of the aorta with lesions (P < 0.0179). These data suggest that 6F acts in the small intestine and provides a novel approach to oral apoA-I mimetic therapy. PMID:23378594

To assess the effect of long-term oral nucleos(t)ide analogues (NUCs) therapy on liver volume change in patients with suppress hepatitis B virus (HBV)-related liver cirrhosis. We reviewed the data of naïve patients with HBV-related liver cirrhosis, who had taken oral NUCs therapy, between 2003 and 2007 at Chonbuk University Hospital. We analyzed two consecutive sets of abdominal computerized tomography scans-one at the time of treatment initiation and another at the second-year follow-up. Liver volume was calculated by 3-dimensional liver extraction volumetry program. A total of 55 patients (34 males) were included. There was 114.3 mL ± 167.8 mL (12.9% ± 17.9%) of increase in liver volume during the two years of NUCs therapy (993.8 mL ± 242.8 mL at baseline vs 1108.1 mL ± 263.3 mL at two-year follow-up, P < 0.001). The ratio of the measured baseline liver volume to the estimated standard liver volume was improved from 70.8% to 78.0%. An increase in liver volume was shown not only in patients with compensated cirrhosis ( P = 0.046) but also in those with decompensated cirrhosis ( P < 0.001). Significant factors for volume increases were Child-Turcotte-Pugh grade and model for end-stage liver disease score improvement without virological breakthrough. In multiple linear regression analysis, delta albumin and delta alanine aminotransferase levels showed a significant association with the increase in liver volume ( P = 0.002 and 0.005, respectively). Long-term oral NUCs therapy in patients with HBV-related liver cirrhosis lead to significant increase in liver volume assessed with 3-dimensional liver extraction volumetry program.

Novel Oral Therapies for Opioid-induced Bowel Dysfunction in Patients with Chronic Noncancer Pain.

PubMed

Holder, Renee M; Rhee, Diane

2016-03-01

Opioid analgesics are frequently prescribed and play an important role in chronic pain management. Opioid-induced bowel dysfunction, which includes constipation, hardened stool, incomplete evacuation, gas, and nausea and vomiting, is the most common adverse event associated with opioid use. Mu-opioid receptors are specifically responsible for opioid-induced bowel dysfunction, resulting in reduced peristaltic and secretory actions. Agents that reverse these actions in the bowel without reversing pain control in the central nervous system may be preferred over traditional laxatives. The efficacy and safety of these agents in chronic noncancer pain were assessed from publications identified through Ovid and PubMed database searches. Trials that evaluated the safety and efficacy of oral agents for opioid-induced constipation or opioid-induced bowel dysfunction, excluding laxatives, were reviewed. Lubiprostone and naloxegol are approved in the United States by the Food and Drug Administration for use in opioid-induced constipation. Axelopran (TD-1211) and sustained-release naloxone have undergone phase 2 and phase 1 studies, respectively, for the same indication. Naloxegol and axelopran are peripherally acting μ-opioid receptor antagonists. Naloxone essentially functions as a peripherally acting μ-opioid receptor antagonist when administered orally in a sustained-release formulation. Lubiprostone is a locally acting chloride channel (CIC-2) activator that increases secretions and peristalsis. All agents increase spontaneous bowel movements and reduce other bowel symptoms compared with placebo in patients with noncancer pain who are chronic opioid users. The most common adverse events were gastrointestinal in nature, and none of the drugs were associated with severe adverse or cardiovascular events. Investigations comparing these agents to regimens using standard laxative and combination therapy and trials in special populations and patients with active cancer are

Disseminated granuloma annulare (DGA) is a benign and usually asymptomatic skin disease. However, many patients feel aesthetically disfigured and ask for treatment. Until today, no standard therapy is recommended. To evaluate the safety and efficacy of oral vitamin E treatment compared to the natural course of DGA. This single-centre observational cohort study included 38 consecutive patients with histologically confirmed DGA. 21 patients underwent treatment with oral vitamin E, whereas 17 patients preferred a wait-and-see approach. Complete healing (40%) and improvement (30%) were frequently seen under oral vitamin E therapy. However, DGA also spontaneously disappeared in 31% and improved in 25% of untreated control patients. Vitamin E therapy was very well tolerated. Oral vitamin E treatment is a safe and probably effective therapy for DGA. As the natural course of DGA leads to complete healing or significant improvement in many cases, 'primum nil nocere' should be the maxim.

The future prospects of pharmacogenetics in oral anticoagulation therapy

Coumarins are the mainstay of oral anticoagulation for the treatment and prophylaxis of thromboembolic disorders. They have a narrow therapeutic index and regular monitoring is therefore required to avoid serious adverse effects. There is wide interindividual variability in dosage requirements, which makes anticoagulation response unpredictable. Current dosing titrations are haphazard and inconvenient and poor initial control leads to morbidity, and occasional mortality, because of bleeding and further thromboembolism. Recent discoveries have helped to characterize the factors that contribute to the interindividual variability in responses to coumarins. Patient and environmental factors that affect anticoagulation response to coumarins include age, body size, dietary vitamin K status, concurrent disease and drug interactions. More recently, single nucleotide polymorphisms in the 2C9 isoform of cytochrome P450 (CYP2C9) and vitamin K epoxide reductase (VKOR) have been shown to make significant contributions to the variability in coumarin dosage requirements. Polymorphisms in other genes that mediate the actions of coumarins may also contribute to this variability. Racial and cultural differences influence dosage requirements, which can be explained, at least in part, by genetic and dietary factors. Incorporation of genetic and environmental factors could help in the prediction of more individualized loading and maintenance doses for safer anticoagulation therapy. PMID:16722840

Despite the advances in the treatment of obstructive sleep apnea (OSA) with mandibular advancement appliances (MAA), their effectiveness is dependent on the patients compliance. Our aims were to evaluate the long-term adherence to MAA therapy and patients experiences of the treatment in OSA. Sixty-nine patients (52 males, 17 females; Mean age: 54.4±10.8 years) were included in the study. The subjects were mild (56%) and moderate (44%) OSA patients who had been treated using MAA at least 4 years prior to the study. A phone survey was used to determine the demographic characteristics of the patients, as well as to assess self-reported adherence to therapy, subjective long-term effectiveness, and patient experiences with the appliance. Descriptive statistics, Pearson Chi-square test, and independent samples t-test were used for data analysis. Only 22 (32%) patients reported using the appliance regularly. Most of the non-adherent patients had stopped using their appliances in the first year (55%). The mean duration of appliance use was 33.5 months (Median: 12 months). No significant differences in appliance type, OSA severity, educational level, gender, marital status, income status, employment status or place of residence existed between adherent and non-adherent subjects. Adherent subjects were significantly younger than non-adherent subjects (Age: 50.6 ± 11.9 versus 56.1 ± 9.9, p < 0.05). The most common reasons reported by patients were inability to adapt to the appliance (62%) and pain in the temporomandibular joint (38%). The most common factors associated with continued usage were effectiveness (100%) and ease of use (64%). The overall long-term nonadherence to MAA therapy in mild-to moderate OSA patients was high suggesting that barriers to MAA therapy adherence should be prevented to increase the efficiency of oral appliance treatment in OSA and achieve better outcomes for this disease.

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

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. PMID:25210256

From guidelines to local realities: evaluation of oral rehydration therapy and zinc supplementation in Guatemala.

Diarrhea remains a leading cause of morbidity and mortality for children in low- and middle-income countries throughout the Americas. The World Health Organization (WHO) has developed guidelines on incorporating zinc supplementation (ZS) with traditional oral rehydration therapy (ORT) in order to shorten the duration of diarrheal episodes and to reduce poor health outcomes. Guatemala adopted these guidelines in 2011, but they have not yet been fully implemented at the community level. The objectives of this study were: (1) to co-design an ORT/ZS training program for community members with local health promoters that is appropriate to the local context and (2) to understand how attitudes and behaviors of community members changed after receiving training from the study promoters. In an observational study, community health promoters in rural Guatemala were trained according to WHO guidelines, and they worked collaboratively with the study team to develop a training curriculum to implement in their community. Community-based surveys, interviews, and focus group discussions were used to assess acceptability, accessibility, and availability of oral rehydration therapy and zinc supplementation. Use of ORT increased from 63% to 95% among community members following training by local health promoters. Satisfaction with the service offered by health promoters increased from 63% to 90% amongst community members trained by the study promoters. However, knowledge and use of zinc supplementation remained low, which was attributable to unavailability of zinc in the study community. Use of trained community health promoters is an effective way to translate WHO guidelines to local contexts and overcome sociocultural barriers to care. However, the health system's structure must support availability of essential medicines in order to effectively implement those guidelines.

Oral ciprofloxacin: a pharmacoeconomic evaluation of its use in the treatment of serious infections.

PubMed

Balfour, J A; Faulds, D

1993-05-01

The broad spectrum of antibacterial activity and favourable pharmacokinetic profile of ciprofloxacin permit oral treatment of many serious infections which have traditionally necessitated parenteral antibacterial therapy. This has been demonstrated in comparative studies, in which ciprofloxacin was as effective and well tolerated as standard parenteral therapies (usually aminoglycoside/beta-lactam combinations or broad spectrum cephalosporins) in small numbers of patients with infections of the lower respiratory tract, urinary tract, skin and soft tissue, and bones and joints. Oral ciprofloxacin is considerably less expensive than most parenteral therapies, does not necessitate therapeutic drug monitoring and can be administered on an outpatient basis. In addition, administration by the oral route is more comfortable and convenient for the patient. Pharmacoeconomic studies have confirmed that substitution of oral ciprofloxacin for parenteral therapy in the treatment of serious infections can achieve considerable savings in drug acquisition costs, and labour and supplies associated with parenteral drug administration, and may allow early discharge from hospital, resulting in even greater savings. Mean reductions of 43 to 83% were achieved in antibacterial costs in 3 randomised prospective studies, when patients received oral ciprofloxacin instead of various parenteral agents, from the beginning of treatment, or after 3 days' parenteral therapy. It can be concluded that oral ciprofloxacin offers considerable scope for cost avoidance when appropriately substituted for parenteral therapy in the treatment of serious infections.

The deoxycytidine analog decitabine (DAC) can deplete DNA methyl-transferase 1 (DNMT1) and thereby modify cellular epigenetics, gene expression, and differentiation. However, a barrier to efficacious and accessible DNMT1-targeted therapy is cytidine deaminase, an enzyme highly expressed in the intestine and liver that rapidly metabolizes DAC into inactive uridine counterparts, severely limiting exposure time and oral bioavailability. In the present study, the effects of tetrahydrouridine (THU), a competitive inhibitor of cytidine deaminase, on the pharmacokinetics and pharmacodynamics of oral DAC were evaluated in mice and nonhuman primates. Oral administration of THU before oral DAC extended DAC absorption time and widened the concentration-time profile, increasing the exposure time for S-phase–specific depletion of DNMT1 without the high peak DAC levels that can cause DNA damage and cytotoxicity. THU also decreased interindividual variability in pharmacokinetics seen with DAC alone. One potential clinical application of DNMT1-targeted therapy is to increase fetal hemoglobin and treat hemoglobinopathy. Oral THU-DAC at a dose that would produce peak DAC concentrations of less than 0.2μM administered 2×/wk for 8 weeks to nonhuman primates was not myelotoxic, hypomethylated DNA in the γ-globin gene promoter, and produced large cumulative increases in fetal hemoglobin. Combining oral THU with oral DAC changes DAC pharmacology in a manner that may facilitate accessible noncytotoxic DNMT1-targeted therapy. PMID:22160381

The aim of the present study was to assess the histopathological effects of low-level laser therapy (LLLT) on healing of the oral mucosa after soft tissue graft operations. The alterations at the end of healing in normal and LLLT-applied oral mucosa were studied in two healthy adult New Zealand white rabbits by taking specimens for light microscopic inspection. There was no adverse event reported in the study and no post-operative complications, such as swelling, bleeding, or edema, were observed in the rabbits. Complete wound healing was faster in the LLLT-applied rabbit. Compared to the normal rabbit oral mucosa, thickening of the stratum corneum (hyperkeratosis) was found in the epithelia of the rabbits. A significant increase in the epithelial thickness was found in the samples of rabbits, suggesting increased scar tissue following the wound repair. Additionally, many mitotic figures were present in the epithelia of the LLLT-applied rabbit, indicating epithelial cell hyperplasia. Long and irregular connective tissue protrusions projecting into the undersurface of the epithelium and mononuclear cell infiltrations were noted in the rabbits. The results suggest that LLLT used for soft tissue operations provides better and faster wound healing and that LLLT enhances epithelization.

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.

The aim of this prospective case series was to assess the clinical efficiency of an oral hygiene protocol in patients affected by mucous membrane pemphigoid (MMP) with specific gingival localization, before starting any medical treatment. Patients received oral hygiene instruction followed by non-surgical periodontal therapy including oral hygiene instructions in a 3-week cohort study. Clinical outcome variables were recorded at baseline and 5 weeks after intervention and included, as periodontal parameters, full mouth plaque (FMPS) and bleeding (FMBS) scores and patient-related outcomes (visual analogue score of pain). A total of 12 patients were recruited. The mean age at presentation was 59.5 ± 14.52 years. Five weeks after finishing the oral hygiene and periodontal therapy protocol, a statistical significant reduction was observed for FMPS (P = 0.001), FMBS (P = 0.022) and reported pain (P = 0.0028). Professional oral hygiene procedures and non-surgical periodontal therapy are connected with improvement of gingival status and decrease in gingival-related pain, in female patients affected by MMP with specific gingival localization. © 2011 John Wiley & Sons A/S.

The primary objective was to evaluate safety of 3-(1'-hexyloxyethyl)pyropheophorbide-a (HPPH) photodynamic therapy (HPPH-PDT) for dysplasia and early squamous cell carcinoma of the head and neck (HNSCC). Secondary objectives were the assessment of treatment response and reporters for an effective PDT reaction. Patients with histologically proven oral dysplasia, carcinoma in situ, or early-stage HNSCC were enrolled in two sequentially conducted dose escalation studies with an expanded cohort at the highest dose level. These studies used an HPPH dose of 4 mg/m(2) and light doses from 50 to 140 J/cm(2). Pathologic tumor responses were assessed at 3 months. Clinical follow up range was 5 to 40 months. PDT induced cross-linking of STAT3 were assessed as potential indicators of PDT effective reaction. Forty patients received HPPH-PDT. Common adverse events were pain and treatment site edema. Biopsy proven complete response rates were 46% for dysplasia and carcinoma in situ and 82% for squamous cell carcinomas (SCC) lesions at 140 J/cm(2). The responses in the carcinoma in situ/dysplasia cohort are not durable. The PDT-induced STAT3 cross-links is significantly higher (P = 0.0033) in SCC than in carcinoma in situ/dysplasia for all light doses. HPPH-PDT is safe for the treatment of carcinoma in situ/dysplasia and early-stage cancer of the oral cavity. Early-stage oral HNSCC seems to respond better to HPPH-PDT in comparison with premalignant lesions. The degree of STAT3 cross-linking is a significant reporter to evaluate HPPH-PDT-mediated photoreaction. ©2013 AACR.

Oral health during pregnancy.

Silk, Hugh; Douglass, Alan B; Douglass, Joanna M; Silk, Laura

2008-04-15

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

Are community pharmacists equipped to ensure the safe use of oral anticancer therapy in the community setting? Results of a cross-country survey of community pharmacists in Canada.

Oral anticancer agents offer significant benefits over parenteral anticancer therapy in terms of patient convenience and reduced intrusiveness. Oral anticancer agents give many cancer patients freedom from numerous hospital visits, allowing them to obtain their medications from their local community pharmacy. However, a major concern with increased use of oral anticancer agents is shift of responsibility in ensuring the proper use of anticancer agents from the hospital/clinical oncology team to the patient/caregiver and other healthcare providers such as the community pharmacists who may not be appropriately trained for this. This study assessed the readiness of community pharmacists across Canada to play this increased role with respect to oral anticancer agents. Using a structured electronic mailing strategy, a standardized survey was mailed to practicing pharmacists in five provinces where community pharmacists were dispensing the majority of oral anticancer agents. In addition to collecting basic demographic and their practice setting, the survey assessed the pharmacists' knowledge regarding cancer therapy and oral anticancer agents in particular, their education needs and access to resources on oral anticancer agents, the quality of prescriptions for oral anticancer agents received by them in terms of the required elements, their role in patient education, and steps to enhance patient and personal safety. There were 352 responses to the survey. Only 13.6% of respondents felt that they had received adequate oncology education at the undergraduate level and approximately 19% had attended a continuing education event related to oncology in the past 2 years. Only 24% of the pharmacists who responded were familiar with the common doses of oral anticancer agents and only 9% felt comfortable educating patients on these medications. A substantial portion of community pharmacists in Canada lack a solid understanding of oral anticancer agents and thus are poorly

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

SUMMARY The three main oral diseases of humans, that is caries, periodontal diseases and oral candidiasis, are associated with microbiome shifts initiated by changes in the oral environment and/or decreased effectiveness of mucosal immune surveillance. In this review we discuss the role that microbial-based therapies may have in the control of these conditions. Most investigations on the use of microorganisms for management of oral disease have been conducted with probiotic strains with some positive but very discrete clinical outcomes. Other strategies such as whole oral microbiome transplantation or modification of community function by enrichment with health-promoting indigenous oral strains may offer more promise but research in this field is still in its infancy. Any microbial-based therapeutics for oral conditions, however, are likely to be only one component within a holistic preventive strategy that should also aim at modification of the environmental influences responsible for the initiation and perpetuation of microbiome shifts associated with oral dysbiosis.

Early and aggressive fluid therapy is critical in correcting the metabolic complications associated with calf diarrhea. Oral electrolyte therapy can be used with success in calves, but careful consideration should be given to the type of oral electrolyte used. Electrolyte solutions with high osmolalities can significantly slow abomasal emptying and can be a risk factor for abomasal bloat in calves. Milk should not be withheld from calves with diarrhea for more than 12 to 24 hours. Hypertonic saline and hypertonic sodium bicarbonate can be used effectively for intravenous fluid therapy on farms when intravenous catheterization is not possible. Copyright © 2014 Elsevier Inc.

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{sup 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%),more » 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.« less

The rise and fall of dental therapy in Canada: a policy analysis and assessment of equity of access to oral health care for Inuit and First Nations communities.

PubMed

Leck, Victoria; Randall, Glen E

2017-07-20

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

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.

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.

BACKGROUND Oral Δ9-tetrahydrocannabinol (THC) is effective for attenuating cannabis withdrawal and may benefit treatment of cannabis use disorders. Oral fluid (OF) cannabinoid testing, increasing in forensic and workplace settings, could be valuable for monitoring during cannabis treatment. METHODS Eleven cannabis smokers resided on a closed research unit for 51 days, and received daily 0, 30, 60, and 120 mg oral THC in divided doses for 5 days. There was a 5-puff smoked cannabis challenge on the 5th day. Each medication session was separated by 9 days of ad libitum cannabis smoking. OF was collected the evening prior to and throughout oral THC sessions and analyzed by 2-dimensional GC-MS for THC, cannabidiol (CBD), cannabinol (CBN), 11-hydroxy-THC (11-OH-THC), and 11-nor-9-carboxy-THC (THCCOOH). RESULTS During all oral THC administrations, THC OF concentrations decreased to ≤78.2, 33.2, and 1.4 μg/L by 24, 48, and 72h, respectively. CBN also decreased over time with concentrations 10-fold lower than THC, with none detected beyond 69h. CBD and 11-OH-THC were rarely detected, only within 19 and 1.6h post smoking, respectively. THCCOOH OF concentrations were dose-dependent and increased over time during 120 mg THC dosing. After cannabis smoking, THC, CBN, and THCCOOH concentrations showed a significant dose-effect and decreased significantly over time. CONCLUSIONS Oral THC dosing significantly affected OF THCCOOH but minimally contributed to THC OF concentrations; prior ad libitum smoking was the primary source of THC, CBD and CBN. Higher cannabinoid concentrations following active oral THC administrations versus placebo suggest a compensatory effect of THC tolerance on smoking topography. PMID:23938457

Oral leukoplakia is catalogued under the group of "potentially malignant disorders". In daily practice, the World Health Organization definition "white patch or plaque that cannot be characterized clinically or histologically as any other disease" is completed by including the observation that it cannot be removed by simple scraping, thereby distinguishing it from pseudo-membranous candidiasis. The aim of this study is to find a definitive treatment of oral leukoplakia, because of its recurrence and its potentiality to the malignant transformation. There are currently different approaches to oral leukoplakia: scalpel surgery, systemic therapy (carotenoids, vitamins, etc.), electro-cauterization, cryotherapy and the use of the laser. In every lesion, biopsy and histological analysis has been performed to identify the stage and classification of the oral leukoplakia. Laser can be used for the complete excision of the lesion (which is more effective, but also more invasive), for the photodynamic therapy (non-invasive procedure, which requires several applications) or for the vaporization of the lesion (very precise treatment and relatively easy to perform). Laser treatments have shown better healing, less soft tissues retraction and less post-operative pain, comparing with traditional surgery. The use of systemic therapies and smoking habit interruption (where present) has been also useful to reduce the lesions before the clinical treatments. The treatment has always to be supported by histological analysis to identify the risk and consequently planning the clinical approach.

There is an unmet medical need for an effective food allergy therapy; thus, development of therapeutic interventions for food allergy is a top research priority. The food allergen-nonspecific therapies for food-induced anaphylaxis include monoclonal anti-IgE antibodies and Chinese herbs. The food allergen-specific therapies include oral, sublingual, and epicutaneous immunotherapy with native food allergens and mutated recombinant proteins. Diet containing heated milk and egg may represent an alternative approach to oral immunomodulation. Oral food immunotherapy remains an investigational treatment to be further studied before advancing into clinical practice. Copyright © 2011 Elsevier Inc. All rights reserved.

The objective of this study was to ascertain the efficacy of oral paracetamol in closing a symptomatic patent ductus arteriosus (PDA) when used as 'rescue' option. After obtaining ethics approval, a retrospective appraisal of the data from April 2014 to July 2015 was performed. Infants who were administered oral paracetamol either after unsuccessful therapy with ibuprofen or where it was considered contraindicated were included. A previously published echocardiographic scoring schema to stratify for ductal disease severity was used. Using univariate analysis, characteristics of infants with successful closure were compared with partial (a priori reduction in composite score by ≥ 50% of pretreatment) or no closure. Twenty infants with gestation age and birthweight of 25.7 ± 1.5 weeks and 724.1 ± 143 g, respectively, were studied. Complete closure was noted in 10 (50%) infants with additional four infants showing a significant reduction in haemodynamic shunting. Gestational age at birth and at therapy, chronological age at therapy, birthweight and total fluid intake were comparable between the two groups. The pre-therapy composite score had a significant association with successful closure (the higher the echocardiographic score, the lesser the closure). Concomitant furosemide therapy and late-onset sepsis had a high likelihood ratio of unsuccessful closure (11.01 [2-tailed, p = 0.005] and 5.3 [2-tailed, p = 0.07]), respectively. Oral paracetamol may be a possible therapeutic option in premature infants where therapy with first-line agents is unsuccessful or contraindicated. Concomitant sepsis and furosemide administration may affect successful therapy.

To evaluate the effect of ice pack therapy on oral health-related quality of life (OHRQoL) following third molar surgery. All consecutive subjects who required surgical extraction of lower third molars and satisfied the inclusion criteria were randomly allocated into two groups. Subjects in group A were instructed to apply ice packs directly over the masseteric region on the operated side intermittently after third molar surgery. This first application was supervised in the clinic and was repeated at the 24-h postoperative review. Subjects in group A were further instructed to apply the ice pack when at home every one and a half hours on postoperative days 0 and 1 while he/she was awake as described. Group B subjects did not apply ice pack therapy. Facial swelling, pain, trismus, and quality of life (using Oral Health Impact Profile-14 (OHIP-14) instrument) were evaluated both preoperatively and postoperatively. Postoperative scores in both groups were compared. A significant increase in the mean total and subscale scores of OHIP-14 was found in both groups postoperatively when compared with preoperative value. Subjects who received ice pack therapy had a better quality of life than those who did not. Subjects whose postoperative QoL were affected were statistically significantly higher in group B than in group A at all postoperative evaluation points (P < 0.05). Statistically significant differences were also observed between the groups in the various subscales analyzed, with better quality of life seen among subjects in group A. Quality of life after third molar surgery was significantly better in subjects who had cryotherapy after third molar than those who did not have cryotherapy. Cryotherapy is a viable alternative or adjunct to other established modes of improving the quality of life of patients following surgical extraction of third molars.

Several tissue engineering strategies in the form of protein therapy, gene therapy, cell therapy, and their combinations are currently being explored for oral and craniofacial regeneration and repair. Though each of these approaches has advantages, they all have common inherent drawbacks of being expensive and raising safety concerns. Using RNA (encoding therapeutic protein) has several advantages that have the potential to overcome these limitations. Chemically modifying the RNA improves its stability and mitigates immunogenicity allowing for the potential of RNA to become an alternative to protein and gene based therapies. This brief review article focuses on the potential of RNA therapeutics in the treatment of disorders in the oral and craniofacial regions.

Preoperative oral carbohydrate therapy.

Nygren, Jonas; Thorell, Anders; Ljungqvist, Olle

2015-06-01

Management of the postoperative response to surgical stress is an important issue in major surgery. Avoiding preoperative fasting using preoperative oral carbohydrates (POC) has been suggested as a measure to prevent and reduce the extent to which such derangements occur. This review summarizes the current evidence and rationale for this treatment. A recent review from the Cochrane Collaboration reports enhanced gastrointestinal recovery and shorter hospital stay with the use of POC with no effect on postoperative complication rates. Multiple randomized controlled trials demonstrate improved postoperative metabolic response after POC administration, including reduced insulin resistance, protein sparing, improved muscle function and preserved immune response. Cohort studies in patients undergoing major abdominal surgery have shown that the use of POC as part of an enhanced recovery after surgery protocol is a significant predictor for improved clinical outcomes. Avoiding preoperative fasting with POC is associated with attenuated postoperative insulin resistance, improved metabolic response, enhanced perioperative well-being, and better clinical outcomes. The impact is greatest for patients undergoing major surgeries.

Cost-minimisation analysis of subcutaneous methotrexate versus biologic therapy for the treatment of patients with rheumatoid arthritis who have had an insufficient response or intolerance to oral methotrexate.

This study aims to model the economic impact of subcutaneous methotrexate (SC MTX) or a biologic over a 12-month period using a hypothetical population of rheumatoid arthritis patients who failed to tolerate or respond to oral MTX and were suitable candidates for biologic therapy. A decision-based model was developed using current National Institute for Health and Clinical Excellence (NICE) guidance to determine the management of this hypothetical UK population. Published data on the continuation rates of SC MTX and biologics were used to compare the costs of the two treatment options. The economic model used a cost-minimisation methodology from a UK National Health Service (NHS) perspective, with the cost of all drugs and resources being estimated on this basis. Sensitivity analyses were also performed to determine the effects of changing key assumptions on the mean cost differences. The routine use of SC MTX following oral MTX failure has the potential to save an estimated £7,197 per patient in the first year of therapy and £9.3m per year nationally in new patients. Sensitivity analyses support the robustness of the results. The results of this study suggest that routine use of SC MTX following oral MTX failure has the potential to provide considerable savings to the NHS through optimised use of MTX first-line therapy. It is proposed, therefore, that patients should start on oral MTX with a subsequent switch to SC MTX in the case of an insufficient response or tolerability issues, before introducing a biologic agent.

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.

An operational study of a 3-tier strategy for implementation of oral rehydration therapy (ORT) was conducted in a block of West Bengal with 216,825 population through the existing health services facilities. All the grassroot level, health workers including their supervisors at various levels were trained regarding the management of patients of diarrhoea with mild to moderate degree of dehydration, by ORT. Another block in the same district with similar demographic features where this intervention was not provided served as control. After 22 months of observation, it was evident that despite adequate training, the performance of Community Health Guides (CHGs) and Anganwadi Workers (AWWs) was not encouraging because of the low utilization of both home available fluids (32.0%) and oral rehydration solution (18.0%) in the study area. Similarly, diarrhoea associated mortality could not be reduced significantly. Lack of motivation and failure to maintain sustained level of skill by the CHGs and AWWs constitute the major bottlenecks for the successful implementation of the programme at the community level.

Due to the recent advances in radiological diagnostic technology, the role of video-assisted thoracoscopic surgery in thoracic disease has expanded, surgical indication extended to the elderly patients. Cancer patients receiving surgery, radiation therapy and/or chemotherapy may encounter complications in conjunction with the oral cavity such as aspiration pneumonia, surgical site infection and various type of infection. Recently, it is recognized that oral health care management is effective to prevent the postoperative infectious complications, especially pneumonia. Therefore, oral management should be scheduled before start of therapy to prevent these complications as supportive therapy of the cancer treatment. In this background, perioperative oral function management is highlighted in the remuneration for dental treatment revision of 2012,and the importance of oral care has been recognized in generally. In this manuscript, we introduce the several opinions and evidence based on the recent previous reports about the perioperative oral health care and management on thoracic surgery.

Hormonal Treatment of Transgender Women with Oral Estradiol.

2018-01-01

Purpose: Maintaining cross-sex hormone levels in the normal physiologic range for the desired gender is the cornerstone of transgender hormonal therapy, but there are limited data on how to achieve this. We investigated the effectiveness of oral estradiol therapy in achieving this goal. Methods: We analyzed data on all transgender females seen in our clinic since 2008 treated with oral estradiol. We looked at the success of achieving serum levels of testosterone and 17-β estradiol in the normal range on various doses of estradiol (with and without antiandrogens spironolactone and finasteride). Results: There was a positive correlation between estradiol dose and 17-β estradiol, but testosterone suppression was less well correlated. Over 70% achieved treatment goals (adequate 17-β estradiol levels and testosterone suppression) on 4 mg daily or more. Nearly a third of patients did not achieve adequate treatment goals on 6 or even 8 mg daily of estradiol. Spironolactone, but not finasteride, use was associated with impairment of obtaining desired 17-β estradiol levels. Spironolactone did not enhance testosterone suppression, and finasteride was associated with higher testosterone levels. Conclusions: Oral estradiol was effective in achieving desired serum levels of 17-β estradiol, but there was wide individual variability in the amount required. Oral estradiol alone was not infrequently unable to achieve adequate testosterone suppression. Spironolactone did not aid testosterone suppression and seemed to impair achievement of goal serum 17-β estradiol levels. Testosterone levels were higher with finasteride use. We recommend that transgender women receiving estradiol therapy have hormone levels monitored so that therapy can be individualized.

We assess current general knowledge of systemic and oral cGVHD, and present general treatment recommendations based on literature review and our clinical experience. Additionally, we review areas where the understanding of oral cGVHD could be improved by further research, and address tools with which to accomplish the long-term goal of providing better health and quality-of-life to patients with cGVHD.

This study compares the outcomes using VitalStim therapy to outcomes using traditional swallowing therapy for deglutition disorders. Twenty-two patients had an initial and a followup videofluoroscopic swallowing study or fiberoptic endoscopic evaluation of swallowing and were divided into an experimental group that received VitalStim treatments and a control group that received traditional swallowing therapy. Outcomes were analyzed for changes in oral and pharyngeal phase dysphagia severity, dietary consistency restrictions, and progression from nonoral to oral intake. Results of chi(2) analysis showed no statistically significant difference in outcomes between the experimental and control groups.

Oral rehydration is the standard in most current guidelines for young children with acute gastroenteritis (AGE). Failure of oral rehydration can complicate the disease course, leading to morbidity due to severe dehydration. We aimed to identify prognostic factors of oral rehydration failure in children with AGE. A prospective, observational study was performed at the Emergency department, Erasmus Medical Centre, Rotterdam, The Netherlands, 2010-2012, including 802 previously healthy children, ages 1 month to 5 years with AGE. Failure of oral rehydration was defined by secondary rehydration by a nasogastric tube, or hospitalization or revisit for dehydration within 72 hours after initial emergency department visit. We observed 167 (21%) failures of oral rehydration in a population of 802 children with AGE (median 1.03 years old, interquartile range 0.4-2.1; 60% boys). In multivariate logistic regression analysis, independent predictors for failure of oral rehydration were a higher Manchester Triage System urgency level, abnormal capillary refill time, and a higher clinical dehydration scale score. Early recognition of young children with AGE at risk of failure of oral rehydration therapy is important, as emphasized by the 21% therapy failure in our population. Associated with oral rehydration failure are higher Manchester Triage System urgency level, abnormal capillary refill time, and a higher clinical dehydration scale score.

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 (P<0.001, 0.003, respectively). Fasting, age, performance status, presence of metastases and type of hormonal therapy were not good predictors of adherence. While most of patients receiving OHT for BC are fasting during Ramadan, this does not negatively impact compliance with treatment. Copyright © 2012. Published by Elsevier B.V.

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 < 0.05). Mean CD4%, immune-status and history of recurrent 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 < 0.05) and a positive correlation between number of CDT and Candida cfu-counts in HIV+ and HIV-. Mean CD4% and immune-status had no influence on Candida isolation. Absence of antiretroviral therapy and HAART increased the probability of Candida isolation (P < 0.05). The HIV infected 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.

Treatment of primary hyperhidrosis with oral anticholinergic medications: a systematic review.

Primary hyperhidrosis is a condition characterized by excessive sweating. Patients are treated off-license with oral anticholinergic medications and report adverse events associated with systemic anticholinergic interactions. This review assesses clinical evidence of efficacy, impact on quality of life and adverse events associated with oral anticholinergic therapy for primary hyperhidrosis. PRISMA guidelines were implemented to complete a systematic review (PROSPERO:CRD42016036326). MEDLINE, EMBASE and PubMed were searched from 1946 to 2015. Inclusion criteria included observational and experimental studies, anticholinergic medication use in primary hyperhidrosis, oral therapy and clear diagnostic and outcome measures. Twenty-three articles relevant to the inclusion criteria were analysed. Oxybutynin therapy improved symptoms in an average of 76.2% (range 60-97%) patients and improved QOL in 75.6% (range 57.6-100%) of patients. Methantheline bromide therapy was associated with a 41% reduction in axillary sweating, 16.4% reduction in palmar sweating, 25% decrease in HDSS score and 40.9% increase in DLQI score. Outcome measures of glycopyrrolate therapy were too variable to collate. Dry mouth was reported in 73.4% (range 43.3-100%) of participants taking oxybutynin 10 mg/day, 38.6% (range 27.8-63.2%) of patients taking glycopyrrolate and 68.8% of patients taking methantheline bromide. Nine studies reported that patients stopped therapy due to adverse events. In eight of these studies, a mean of 10.9% of total participants ceased treatment due to dry mouth. Evidence of oral anticholinergic therapy for hyperhidrosis is limited. However, its use is associated with improvement in quality of life and clinical symptoms but at the cost of considerable adverse events. © 2016 European Academy of Dermatology and Venereology.

Incidence of oral thrush in patients with COPD prescribed inhaled corticosteroids: Effect of drug, dose, and device.

Little information is available on real-life occurrence of oral thrush in COPD patients treated with ICS. We investigated oral thrush incidence in COPD patients prescribed FDC ICS/LABA therapies and assessed whether it is modulated by the ICS type, dose, and delivery device. We conducted a historical, observational, matched cohort study (one baseline year before and one outcome year after initiation of therapy) using data from the UK Optimum Patient Care Research Database. We assessed oral thrush incidence in patients initiating long-acting bronchodilators or FDC ICS/LABA therapy. We then compared different combination therapies (budesonide/formoterol fumarate dihydrate [BUD/FOR] and fluticasone propionate/salmeterol xinafoate [FP/SAL]) and devices (DPI and pMDI). Patients prescribed FDC ICS/LABA had significantly greater odds of experiencing oral thrush than those prescribed long-acting bronchodilators alone (adjusted OR 2.18 [95% CI 1.84-2.59]). Significantly fewer patients prescribed BUD/FOR DPI developed oral thrush compared with FP/SAL DPI (OR 0.77 [0.63-0.94]) when allowing for differences in prescribed doses between the drugs. A significantly smaller proportion of patients developed oral thrush in the FP/SAL pMDI arm than in the FP/SAL DPI arm (OR 0.67 [0.55-0.82]). Additionally, in the FP/SAL cohort (both DPI and pMDI), increased risk of oral thrush was significantly associated with high ICS daily dose (OR 1.97 [1.22-3.17] vs low daily dose). ICS use increases oral thrush incidence in COPD and this effect is dose-dependent for FP/SAL therapies. Of the therapies assessed, FP/SAL pMDI and BUD/FOR DPI may be more protective against oral thrush. Copyright © 2016 Elsevier Ltd. All rights reserved.

Oral mucositis in head and neck cancer: risk, biology, and management.

Sonis, Stephen T

2013-01-01

Of the toxicities associated with conventional forms of treatment for head and neck cancers, probably none has such a consistent legacy as oral mucositis.1 Despite the fact that mucosal injury was noted as far back as Marie Curie's first forays into therapeutic radiation, an effective intervention has yet to be developed. In addition to its historic link to radiation, new therapeutic strategies including induction chemotherapy often produce mucositis, and targeted therapies appear to alter mucositis risk and its severity and course.2 The symptomatic effect of oral mucositis is profound. Disabling oral and oropharyngeal pain prevents patients from eating normally, requires opiate analgesics, and in some cases results in alteration or discontinuation of anticancer therapy.3 Furthermore, the health and economic consequences of oral mucositis are far from trivial. The incremental cost of oral mucositis in patients with head and neck cancer exceeds $17,000 (USD).4.

Examining drug exposure is essential to pharmacovigilance, especially for bisphosphonate (BP) therapy. To examine differences in 4 measures of oral BP exposure: treatment discontinuation, adherence, persistence, and nonpersistence. Among women aged ≥ 50 years who initiated oral BP therapy during 2002-2007 with at least 3 years of health plan membership follow-up, discontinuation was defined by evidence of no further treatment during the study observation period. Among those with at least 2 filled BP prescriptions during the study period, adherence was calculated for each year of follow-up using the (modified) proportion of days covered (mPDC) metric that allows for stockpiling of prescription/refills overlap ≤ 30 days supply. Persistence was quantified by treatment duration, allowing a gap of up to 60 days between prescription/refill days covered. Nonpersistence was quantified by the periods without drugs outside this allowable gap. Multivariable logistic regression was used to compare age and race groups and the relationships of early adherence (adherence during the first year) with subsequent adherence. Among 48,390 women initiating oral BP therapy and followed for 3 years, 26.7% discontinued in year 1, and 14.7% of the remaining 35,456 women discontinued in year 2. Discontinuation rates were slightly higher (29.4%, P < 0.001) for women aged ≥ 75 years and somewhat lower (21.1%, P < 0.001) for Asian women. During the first year, 60.4% of the women achieved an mPDC of ≥ 75%, with demographic differences in adherence similar to that seen for treatment discontinuation. Over the 3 years, the median mPDC levels for BP therapy were 86%, 84%, and 85% in years 1, 2, and 3, respectively, for those receiving treatment. Cumulative persistence was 2.3 years (median, IQR = 1.0-3.0) overall and slightly greater for Asian versus white women and lower for older women. There were 18,174 (42.9%) women with at least 1 period of nonpersistence during 3 years follow-up in

Exploring scarless healing of oral soft tissues.

Our research group is comparing clinical, histological and molecular healing profiles of oral and skin wounds using human and pig models. The goal is to determine the molecular cues that lead to scarless healing in the oral mucosa and use that information to develop scar prevention therapies for skin and prevent aberrant wound healing in the oral cavity. Wound healing in human and pig palatal mucosa is almost identical, and scar formation is reduced in oral wounds compared with skin. The striking difference between these tissues is transient and rapidly resolving inflammation in oral wounds compared with long-lasting inflammation in the skin wounds. Currently, we are looking at wound transcriptomes (genes differentially regulated) and proteomes (a set of proteins) to investigate how these wound healing responses in skin and oral mucosa are regulated at the molecular level.

Alternative antiretroviral therapy formulations for patients unable to swallow solid oral dosage forms.

Evidence-based guidance is presented to assist clinicians in selecting alternative formulations of antiretroviral (ARV) agents for patients with human immunodeficiency virus (HIV) infection who are unable to swallow tablets or capsules. The inability to take medications in standard oral dosage forms can be associated with nonadherence or the use of alternative administration strategies such as capsule or tablet breaking, crushing, or chewing. Patients with HIV infection require long-term ARV therapy to maintain viral suppression; ARV agents are predominately available as tablets and capsules that may pose swallowing difficulties for some patients. Using a variety of sources (the primary literature, pharmaceutical package inserts, and requests for unpublished data from drug manufacturers), available evidence on the bioavailability of ARV medications after disruption of the capsule or tablet matrix was reviewed; information on alternative formulations of ARV agents was also assessed. With several ARV agents, disruption of the solid oral dosage form by crushing, chewing, or breaking tablets or opening capsules prior to ingestion has been shown to result in altered bioavailability or pharmacokinetics and thus the potential for incomplete virological suppression, increased adverse effects, and suboptimal health outcomes. Of the 33 single-agent ARV medications and combination ARV products in five classes available at the time of review, approximately half exist as powders, liquids, injectables, or chewable or dissolvable tablets. If alternative ARV formulations or administration methods are used, close monitoring for achievement of virological and immunologic success and potential toxicities is recommended.

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 (< 1.00) were significantly increased from 1.5 to 1.8 times for an increase of 1 standard deviation (SD) in symptoms of depression, anxiety, worrying and anger, respectively, after adjusting for gender, age, body mass index, socioeconomic status, hematocrit and C-reactive protein. Worrying, anger and hostility also showed significant direct associations with FVII:C. In patients with OAC 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.

Oral pemphigus vulgaris: a case report and literature update.

Pemphigus vulgaris is a rare cause of oral mucosal ulceration. A 47-year-old Chinese man presented with a 3-month history of oral ulceration. There were no lesions on the skin or other mucosal sites. Histology and immunostaining were consistent with pemphigus vulgaris. Systemic and topical corticosteroids were instituted, together with topical antifungals. Conventional periodontal therapy was carried out to improve gingival/oral health. Control of oral ulceration was achieved with re-establishment of normal oral function. No other sites to date have been involved. Chronic oral ulceration can be the sole manifestation of pemphigus vulgaris, at least initially. Early recognition of this lesion may prevent delayed diagnosis and inappropriate treatment of a potentially chronic dermatological condition.

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

Oral manifestations of paracoccidioidomycosis (South American blastomycosis).

1991-10-01

Paracoccidioidomycosis (South American blastomycosis) is an uncommon, progressive systemic mycosis, potentially fatal if untreated. It is virtually restricted to persons spending time in Latin America. Reports of oral lesions are extremely rare in the English-language literature. Three adults with oral lesions as the first sign of paracoccidioidomycosis are described; this appears to be the largest series in the dental literature. The oral lesions had a characteristic appearance with a granular purpuric surface. The upper gingiva was a typical site, but lesions were also seen in the palate, tongue, and buccal mucosa. Two of the patients proved to have detectable pulmonary involvement. Long-term systemic ketoconazole therapy produced resolution of oral lesions in all cases.

Novel oral anticoagulants for atrial fibrillation.

Anticoagulation therapy is effective in preventing primary and secondary thromboembolic events due to atrial fibrillation. Warfarin, which was approved by the United States in 1954, was the only long-term oral anticoagulation therapy till the approval of dabigatran in 2010, and of rivaroxaban and other direct factor Xa inhibitors from 2011, forming a group known as novel oral anticoagulants (NOAC). NOAC have fewer food and drug interactions compared to warfarin; hence, the patient will require fewer clinic visits. However, the short half-life of NOAC means that twice-a-day dosing is needed and there is higher risk of a prothrombotic state when doses are missed. Other disadvantages are the lack of long-term data on NOAC, their high cost and the current lack of locally available antidotes.

Candida infections are frequently encountered fungal infections in the oral mucosa. This study aimed to evaluate the effect of eliminating Candida spp. on stimulated whole salivary flow rate (SWS) in patients with oral candidiasis. This study involved 66 patients with oral candidiasis. Fifty-two consecutive patients, successfully treated by antifungal therapy, were available to examine the effect of elimination of oral Candida spp. on SWS (success group); the 14 patients who tested positive for Candida after therapy were retrospectively included (control group). SWS were used to measure saliva production. Moreover, tongue pain and xerostomia were evaluated using visual analog score (VAS). By eliminating oral Candida spp., SWS significantly increased in the success group after antifungal therapy [SWS: mean value 0.89±0.51ml/min (median 0.82ml/min: 0.15-2.14) to mean value 1.16±0.58ml/min (median 1.05ml/min: 0.2-2.93), P<0.001]. Furthermore, VAS scores for subjective tongue pain and xerostomia were significantly decreased compared with those before therapy in the success group [xerostomia: mean value 52.5±28.8 (median 53: 9-100) to 24.2±1.6 (median 17: 0-70), tongue pain: mean value 52.6±27.2 (median 56: 1-93) to 15.3±18.0 (median 9: 0-62). P<0.001]. There was no significant difference in SWS, subjective tongue pain, or xerostomia in the control group after antifungal therapy. [SWS: mean value 1.08±0.83ml/min (median 0.69ml/min: 0.2-2.7) to 0.98±0.59ml/min (median 0.8ml/min: 0.45-2.5), P=0.65], [xerostomia: mean value 62.8±5.3 (median 62: 28-70) to 64.0±8.8 (median 64: 56-73), P=0.58, tongue pain: mean value 64.3±18.6 (median 67: 31-87) to 58.4±20.0 (median 8: 20-78), respectively; P=0.24] CONCLUSION: Our study demonstrated that SWS may increase by eliminating oral Candida spp. in patients with oral candidiasis.

We review the use of topical chemoprevention agents in patients with oral potentially malignant disorders (PMD). A systematic review of studies on topical chemoprevention agents for oral PMD from 1946 to November 2016 was conducted using the MEDLINE database, Embase, and Cochrane Library. Data were extracted and analyzed from selected studies including study type, sample size, demographics, treatment length, response rate, follow-up time, adverse effects, and recurrence. Of 108 studies, twenty-four, representing 679 cases met the inclusion criteria. The clinical lesions evaluated included oral leukoplakia, erythroplakia (OEL), verrucous hyperplasia (OVH), oral lichen planus, larynx squamous cell carcinoma, and oral squamous cell carcinoma (OSCC). The mean complete response rate for topical retinoid therapy was 32%. The mean complete response rate for 1% bleomycin therapy and 0.5% bleomycin was 40.2% and 25%, respectively. The complete response rate of OVH, OEL, and OSCC to photodynamic therapy ranged from 66.7% to 100%. There are a paucity of data examining topical treatment of oral PMDs. However, the use of topical agents among patients with oral lesions may be a viable complement or even alternative to traditional surgery, radiation, or systemic chemotherapy, with the advantage of reducing systemic side effects and sparing important anatomic structures. This study of 679 cases represents the largest pooled sample size to date, and the preliminary studies in this systematic review provide support for further inquiry. Copyright © 2017 Elsevier Ltd.

Intra-abdominal infections are a substantial clinical problem and an important cause of morbidity and death in the hospital. Optimal treatment requires both source control and antibiotic therapy. Sequential intravenous (IV) to oral therapy may improve patient convenience and reduce total health care costs. In this randomized, double-blind trial, the efficacy of sequential IV-to-oral ciprofloxacin plus metronidazole was compared with ceftriaxone plus metronidazole in adult patients with complicated intra-abdominal infections. The trial enrolled 531 patients, who began with IV therapy. Patients who improved clinically were switched to oral therapy on day three or later. The clinical and bacteriological responses four to six weeks after the end of therapy and the safety of the two regimens were assessed. To maintain blinding, the patients received placebo IV in the ciprofloxacin group or placebo orally in the ceftriaxone group. A total of 475 patients (235 ciprofloxacin plus metronidazole, 240 ceftriaxone plus metronidazole) were valid for evaluation of efficacy. All patients were included in the safety analysis. Of the patients valid for efficacy, 78% of the ciprofloxacin plus metronidazole group and 81% of the ceftriaxone plus metronidazole group were eligible for a switch to oral therapy. The clinical success rates were 98.9% and 96.9%, respectively, which were statistically equivalent. The clinical success rates for all patients, including those on continuous IV therapy, were 90.6% and 87.9%. Source control was achieved in more than 90% of the patients. The bacteriological eradication rates were similar in the two groups. Bacterial complications (e.g., surgical site infections, abscesses) were encountered more often in the ceftriaxone plus metronidazole group. Sequential ciprofloxacin plus metronidazole IV-to-oral therapy was statistically equivalent to ceftriaxone plus metronidazole. The switch to oral therapy with ciprofloxacin plus metronidazole was as

Ocular changes with oral and transepidermal diethylcarbamazine therapy of onchocerciasis.

Taylor, H R; Greene, B M

1981-01-01

Twenty men with moderate infection of Onchocerca volvulus were studied in a double-masked, controlled clinical trial to compare the safety and efficacy of oral diethylcarbamazine (DEC) with topical DEC lotion. Visual acuity and colour vision did not alter during the 6 months of observation, although 2 patients receiving DEC lotion and 3 patients receiving oral DEC developed either visual field constriction or optic atrophy. Fluffy corneal opacities were common in both groups. Intraocular microfilariae also appeared in both groups but to a greater extent in those receiving DEC lotion. New chorioretinal changes developed in 4 men receiving lotion and in only 1 receiving tablets. It is concluded that DEC lotion offers no advantage over tablets in the treatment of ocular onchocerciasis and in fact may be associated with more ocular complications than the conventional oral treatment.

Adolescent females with ovarian failure require estrogen therapy for induction of puberty and other important physiologic effects. Currently, health care providers have varying practices without evidence-based standards, thus investigating potential differences between oral and transdermal preparations is essential. The purpose of this study was to compare the differential effects of treatment with oral conjugated equine estrogen (OCEE), oral 17β estradiol (OBE), or transdermal 17β estradiol (TBE) on biochemical profiles and feminization in girls with ovarian failure. 20 prepubertal adolescent females with ovarian failure, ages 12-18 years, were randomized to OCEE (n = 8), OBE (n = 7), or TBE (n = 5) for 24 months. Estrogen replacement was initiated at a low dose (0.15 mg OCEE, 0.25 mg OBE, or 0.0125 mg TBE) and doubled every 6 months to a maximum dose of 0.625 mg/d OCEE, 1 mg/d OBE, or 0.05 mg/d TBE. At 18 months, micronized progesterone was added to induce menstrual cycles. Biochemical markers including sex hormones, inflammatory markers, liver enzymes, coagulation factors, and lipids were obtained at baseline and 6 month intervals. Differences in levels of treatment parameters between the groups were evaluated with one-way analysis of variance (ANOVA). The effect of progesterone on biochemical markers was evaluated with the paired t-test. Mean (±SE) estradiol levels at maximum estrogen dose (18 months) were higher in the TBE group (53 ± 19 pg/mL) compared to OCEE (14 ± 5 pg/mL) and OBE (12 ± 5 pg/mL) (p ≤ 0.01). The TBE and OBE groups had more effective feminization (100% Tanner 3 breast stage at 18 months). There were no statistical differences in other biochemical markers between treatment groups at 18 months or after the introduction of progesterone. Treatment with transdermal 17β estradiol resulted in higher estradiol levels and more effective feminization compared to oral conjugated equine estrogen but

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

Bone and joint infection in adults arises most commonly as a complication of joint replacement surgery, fracture fixation and diabetic foot infection. The associated morbidity can be devastating to patients and costs the National Health Service an estimated £20,000 to £40,000 per patient. Current standard of care in most UK centres includes a prolonged course (4-6 weeks) of intravenous antibiotics supported, if available, by an outpatient parenteral antibiotic therapy service. Intravenous therapy carries with it substantial risks and inconvenience to patients, and the antibiotic-related costs are approximately ten times that of oral therapy. Despite this, there is no evidence to suggest that oral therapy results in inferior outcomes. We hypothesise that, by selecting oral agents with high bioavailability, good tissue penetration and activity against the known or likely pathogens, key outcomes in patients managed primarily with oral therapy are non-inferior to those in patients treated by intravenous therapy. The OVIVA trial is a parallel group, randomised (1:1), un-blinded, non-inferiority trial conducted in thirty hospitals across the UK. Eligible participants are adults (>18 years) with a clinical syndrome consistent with a bone, joint or metalware-associated infection who have received ≤7 days of intravenous antibiotic therapy from the date of definitive surgery (or the start of planned curative therapy in patients treated without surgical intervention). Participants are randomised to receive either oral or intravenous antibiotics, selected by a specialist infection physician, for the first 6 weeks of therapy. The primary outcome measure is definite treatment failure within one year of randomisation, as assessed by a blinded endpoint committee, according to pre-defined microbiological, histological and clinical criteria. Enrolling 1,050 subjects will provide 90 % power to demonstrate non-inferiority, defined as less than 7.5 % absolute increase in treatment

Background. Intravenous alemtuzumab and fludarabine are effective in combination for the treatment of chronic lymphocytic leukemia (CLL), but require hospital visits for intravenous injection. We performed a pilot study to assess the safety and efficacy of outpatient-based oral fludarabine with subcutaneous alemtuzumab (OFSA) for the treatment of relapsed/refractory CLL. Results. Depending on their response, patients were given two to six 28-day cycles of subcutaneous alemtuzumab 30 mg on days 1,3, and 5 and oral fludarabine 40 mg/m2/day for 5 days. Median patient age was 74. The lymphocyte counts of all five patients fell after the 1st cycle of treatment and reached normal/low levels on completion of 2 to 6 cycles of therapy. Platelet counts and hemoglobin were unaffected. All five patients achieved complete hematological remission, while two attained minimal residual disease negativity on 4-color flow cytometry. Conclusions. Our OFSA regimen was effective in elderly Asian patients with relapsed/refractory CLL, and it should be investigated further. PMID:19960058

Field-cancerized tissue can give rise to second primary tumours, causing therapeutic failure. Boron neutron capture therapy (BNCT) is based on biological targeting and would serve to treat undetectable foci of malignant transformation. The aim of this study was to optimize BNCT for the integral treatment for oral cancer, with particular emphasis on the inhibitory effect on tumour development originating in precancerous conditions, and radiotoxicity of different BNCT protocols in a hamster cheek pouch oral precancer model. Groups of cancerized hamsters were locally exposed to single or double (2 or 4 weeks apart) applications of BNCT at different dose levels, mediated by the boron compounds boronophenylalanine (BPA) or BPA and decahydrodecaborate (GB-10) administered jointly. Cancerized, sham-irradiated hamsters served as controls. Clinical status, tumour development from field-cancerized tissue and mucositis were followed for 8 months. A double application (4 weeks apart) of BNCT mediated by GB-10+ BPA at a total dose of 10 Gy in two 5-Gy doses rendered the best therapeutic advantage (63-100% inhibition of tumour development from field-cancerized tissue), minimizing dose-limiting mucositis. BNCT can be optimized for the integral treatment for head and neck cancer, considering the implications for field-cancerized tissue. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To study the potential effects of intensity modulated radiation therapy (IMRT) on clinical efficacy, oral mucosa reaction and immunological foundation; and to explore the effect of immunological changes on clinical efficacy and oral mucosa reaction in patients with nasopharyngeal carcinoma.
 Methods: A total of 200 patients with nasopharyngeal carcinoma, who came from First Department of Nasopharyngeal Radiotherapy, the First People's Hospital of Foshan from October 2008 to November 2011, were selected. The patients were treated with nasopharyngeal radiotherapy, and divided into an observation group and a control group (n=100 in each group). The control group underwent common conventional two-dimensional radiotherapy treatment, while the observation group underwent IMRT. The 5-year survival rates and recurrence rates were recorded at follow-up. After the radiotherapy, the oral mucosa in the patients were evaluated by the classification standard of acute radioactive mucositis by American Radiotherapy Oncology Group (RTOG), and the number of T lymphocyte subsets before and after treatment was detected.
 Results: There were significant difference in non-regional-recurrence survival rate, disease-free survival rate, local recurrence rate between the above 2 groups (all P<0.05), but no significant difference in the distant metastasis-free survival rate (P>0.05). The acute oral mucosa reactions of grade 1, 2, 3, 4 in the control group were 8.00%, 20.00%, 12.00%, 7.00%, respectively, and those were 7.00%, 22.00%, 15.00%, 1.00% respectively. There was no significant difference in the acute response of oral mucosa in grade 1, 2 and 3 in the 2 groups (all P>0.05), but there was significant difference in the grade 4 (P<0.05). There were significantly difference in CD8+, CD4+/ CD8+ and CD4+ T lymphocyte subsets before and after treatment in the above 2 groups (all P<0.01); there were also significantly difference after treatment between the observation group and the

An early switch from intravenous to oral antimicrobial therapy is useful for reducing the duration of the hospitalization in adult patients with community acquired-pneumonia, whereas the efficacy of switch therapy for pediatric patients with community acquired (CA)-lower respiratory tract infection (LRTI) is uncertain. The aim of this study is to investigate the efficacy of switch therapy for LRTI in patients with severe motor intellectual disabilities (SMID). This retrospective study was performed on 92 patients with SMID who were admitted to the Department of Pediatrics at the Hospital of University of Occupational and Environmental Health, Japan from April 1, 2010 to March 31, 2017 for the suspicion of bacterial LRTI and were initially treated with an intravenous antimicrobial agent. Clinical outcomes were compared between patients with switch therapy (Switch therapy group) and conventional intravenous antimicrobial therapy (No switch therapy group). Thirteen and 79 in patients with SMID belonged to Switch thrapy group and No switch therapy group, respectively. Length of hospital stay in Switch therapy group was significantly shorter than that in No switch therapy group (P = 0.002). In the patients undergoing switch therapy, there was no patient who required re-treatment and/or re-hospitalization. Switch therapy for LRTI was useful for the reduction of length of hospital stay without increasing risk of re-treatment and re-hospitalization in patients with SMID.

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

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. PMID:28009823

All artemisinin-based combination therapies (ACTs), recommended by the World Health Organization, are 3-day regimens. A considerable level of non-compliance on ACTs has been reported from some countries. The study aimed to assess the therapeutic efficacy of single dose treatment with new generation ACT containing artemisinin plus naphthoquine. An oral single dose of eight tablets (400 mg of naphthoquine+1000 mg artemisinin) of the combination drug was administered to adult uncomplicated falciparum malaria patients. Observations of fever, parasite clearance and reappearance, and other clinical manifestations were made on Days 0, 1, 2, 3, 7, 14, 21 and 28. Fifty-three adult falciparum positive cases, with fever or history of fever within the previous 24 h, were included in the final evaluation of the study. Mean fever clearance time, parasite clearance time were 18.2+/-8.6 h and 34.6+/-14.3 h, respectively. Adequate clinical and parasitological response was achieved in 52 cases, the rate being 98.1% (95% CI, 91.1-99.9). One patient was classified as late parasitological failure because of the reappearance of falciparum parasite on Day 14. The drug was well tolerated and no adverse reactions were detected in the patients. Since it is a single dose therapy, health workers can administer the drug as directly observed treatment.

Purpose The primary objective was to evaluate safety of 3-(1’-hexyloxyethyl)pyropheophorbide-a (HPPH) photodynamic therapy (HPPH-PDT) for dysplasia and early squamous cell carcinoma of the head and neck (HNSCC). Secondary objectives were the assessment of treatment response and reporters for an effective PDT reaction. Experimental Design Patients with histologically proven oral dysplasia, carcinoma in situ (CiS ) or early stage HNSCC were enrolled in two sequentially conducted dose escalation studies with an expanded cohort at the highest dose level. These studies employed an HPPH dose of 4 mg/m2 and light doses from 50 to 140 J/cm2. Pathologic tumor responses were assessed at 3 months. Clinical follow up range was 5 to 40 months. PDT induced cross-linking of signal transducer and activator of transcription 3 (STAT3) were assessed as potential indicators of PDT effective reaction. Results Forty patients received HPPH-PDT. Common adverse events were pain and treatment site edema. Biopsy proven complete response rates were 46% for dysplasia and CiS, and 82% for SCCs lesions at 140 J/cm2. The responses in the CiS/dysplasia cohort are not durable. The PDT induced STAT3 cross-links is significantly higher (P=0.0033) in SCC than in CiS/dysplasia for all light-doses. Conclusion HPPH-PDT is safe for the treatment of CiS/dysplasia and early stage cancer of the oral cavity. Early stage oral HNSCC appears to respond better to HPPH-PDT in comparison to premalignant lesions. The degree of STAT3 cross-linking is a significant reporter to evaluate HPPH-PDT mediated photoreaction. PMID:24088736

Patients with inflammatory bowel diseases (IBD) may present with lesions in their oral cavity. Lesions may be associated with the disease itself representing an extraintestinal manifestation, with nutritional deficiencies or with complications from therapy. To review and describe the spectrum of oral nonmalignant manifestations in patients with inflammatory bowel diseases [ulcerative colitis (UC), Crohn's disease (CD)] and to critically review all relevant data. A literature search using the terms and variants of all nonmalignant oral manifestations of inflammatory bowel diseases (UC, CD) was performed in November 2014 within Pubmed, Embase and Scopus and restricted to human studies. Oral lesions in IBD can be divided into three categories: (i) lesions highly specific for IBD, (ii) lesions highly suspicious of IBD and (iii) nonspecific lesions. Oral lesions are more common in CD compared to UC, and more prevalent in children. In adult CD patients, the prevalence rate of oral lesions is higher in CD patients with proximal gastrointestinal tract and/or perianal involvement, and estimated to range between 20% and 50%. Oral lesions can also occur in UC, with aphthous ulcers being the most frequent type. Oral manifestations in paediatric UC may be present in up to one-third of patients and are usually nonspecific. Oral manifestations in IBD can be a diagnostic challenge. Treatment generally involves managing the underlying intestinal disease. In cases presenting with local disabling symptoms and impaired quality of life, local and systemic medical therapy must be considered and/or oral surgery may be required. © 2015 John Wiley & Sons Ltd.

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.

2017-02-15

Craniofacial bone defects are challenging problems for maxillofacial surgeons over the years. With the development of cell and molecular biology, gene therapy is a breaking new technology with the aim of regenerating tissues by acting as a delivery system for therapeutic genes in the craniofacial region rather than treating genetic disorders. A systematic review was conducted summarizing the articles reporting gene therapy in maxillofacial surgery to answer the question: Was gene therapy successfully applied to regenerate bone in the maxillofacial region? Electronic searching of online databases was performed in addition to hand searching of the references of included articles. No language or time restrictions were enforced. Meta-analysis was done to assess significant bone formation after delivery of gene material in the surgically induced maxillofacial defects. The search identified 2081 articles, of which 57 were included with 1726 animals. Bone morphogenetic proteins were commonly used proteins for gene therapy. Viral vectors were the universally used vectors. Sprague-Dawley rats were the frequently used animal model in experimental studies. The quality of the articles ranged from excellent to average. Meta-analysis results performed on 21 articles showed that defects favored bone formation by gene therapy. Funnel plot showed symmetry with the absence of publication bias. Gene therapy is on the top list of innovative strategies that developed in the last 10 years with the hope of developing a simple chair-side protocol in the near future, combining improvement of gene delivery as well as knowledge of the molecular basis of oral and maxillofacial structures.

Background For women living with osteoporosis, high out-of-pocket drug costs may prevent drug therapy initiation. We investigate the association between oral osteoporosis out-of-pocket medication costs and female Medicare beneficiaries’ initiation of osteoporosis drug therapy. Methods We used 2007 and 2008 administrative claims and enrollment data for a 5% random sample of Medicare beneficiaries. Our study sample included age-qualified, female beneficiaries who had no prior history of osteoporosis but were diagnosed with osteoporosis in 2007 or 2008. Additionally, we only included beneficiaries continuously enrolled in standalone prescription drug plans. We excluded beneficiaries who had a chronic condition that was contraindicated with osteoporosis drug utilization. Our final sample included 25,069 beneficiaries. Logistic regression analysis was used to examine the association between the out-of-pocket costs and initiation of oral osteoporosis drug therapy during the year of diagnosis. Findings Twenty-six percent of female Medicare beneficiaries newly diagnosed with osteoporosis initiated oral osteoporosis drug therapy. Beneficiaries’ out-of-pocket costs were not associated with the initiation of drug therapy for osteoporosis. However, there were statistically significant racial disparities in beneficiaries’ initiation of drug therapy. African Americans were 3 percentage points less likely to initiate drug therapy than whites. In contrast, Asian/Pacific Islander and Hispanic beneficiaries were 8 and 18 percentage points respectively more likely to initiate drug therapy than whites. Additionally, institutionalized beneficiaries were 11 percentage points less likely to initiate drug therapy than other beneficiaries. Conclusions Access barriers for drug therapy initiation may be driven by factors other than patients’ out-of-pocket costs. These results suggest that improved osteoporosis treatment requires a more comprehensive approach that goes beyond payment

A review of the efficacy and safety of nanoparticle-based oral insulin delivery systems.

Nanotechnology is providing new and innovative means to detect, diagnose, and treat disease. In this regard, numerous nanoparticle-based approaches have been taken in an effort to develop an effective oral insulin therapy for the treatment of diabetes. This review summarizes efficacy data from studies that have evaluated oral insulin therapies in experimental models. Also provided here is an overview of the limited safety data that have been reported in these studies. To date, the most promising approaches for nanoparticle-based oral insulin therapy appear to involve the incorporation of insulin into complex multilayered nanoparticles that are mucoadhesive, biodegradable, biocompatible, and acid protected and into nanoparticles that are designed to take advantage of the vitamin B(12) uptake pathway. It is anticipated that the continued investigation and optimization of nanoparticle-based formulations for oral delivery of insulin will lead to a much sought-after noninvasive treatment for diabetes. Such investigations also may provide insight into the use of nanoparticle-based formulations for peptide- and protein-based oral treatment of other diseases and for various food-related purposes.

Biologics in oral medicine: ulcerative disorders.

O'Neill, I D; Scully, C

2013-01-01

Inflammatory ulcerative diseases of the oral mucosa are wide ranging but include especially aphthous and aphthous-like ulceration, vesiculobullous disorders and erosive lichen planus (LP). While most patients with these conditions respond to conventional topical and/or systemic immunosuppressive agents, treatment-resistant cases remain challenging. In these, the use of biologics such as tumour necrosis factor alpha (TNF-α) inhibitors or rituximab may be of benefit. This article reviews the use of biologics in ulcerative oral conditions, highlighting potential benefits, adverse effects and principles of use and future developments. TNF-α inhibitors such as infliximab can be effective in inducing resolution in oral aphthous and aphthous-like ulcers and may be an appropriate therapy in those patients in which disease is severe and refractory to, or patients are intolerant of, traditional immunomodulatory regimens. There would also seem support and rationale for use of biologics (mainly rituximab) in pemphigus but not in oral LP or other oral ulcerative conditions. © 2012 John Wiley & Sons A/S.

Heterogeneity across trials and possible publication bias were statistically measured. Subgroup analyses (post hoc) were conducted to compare results of self-testing versus self-management, low versus high trial quality, trials conducted in the UK versus trials in other countries and industry versus other sponsors. A Markov-type, state-transition model was developed. Stochastic simulations using the model were conducted to investigate uncertainty in estimated model parameters. In the 16 randomised and eight non-randomised trials selected, patient self-monitoring of oral anticoagulation therapy was found to be more effective than poor-quality usual care provided by family doctors and as effective as good-quality specialised anticoagulation clinics in maintaining the quality of anticoagulation therapy. There was no significant RD of major bleeding events between patient self-monitoring and usual care controls and pooled analyses found that compared with primary care or anticoagulation control (AC) clinics, self-monitoring was statistically significantly associated with fewer thromboembolic events. However, the reduction in complication events and deaths was not consistently associated with the improvement of AC; in some trials this may be due to alternative explanations, including patient education and patient empowerment. Also, the improved AC and the reduction of major complications and deaths by patient self-monitoring were mainly observed in trials conducted outside the UK. According to UK-specific data, for every 100 eligible patients

Aspirin is a commonly used medicine for primary and secondary prevention of cardiovascular diseases. It is an acidic medicine associated with gastric irritation and acid reflux, which in turn can lead to low oral pH levels. Therefore, it is important to understand the association between aspirin and oral pH levels in order to achieve an optimum oral health condition among patients who take aspirin on prescription. Out of 373 patients, 162 (44%) were males and 245 (66%) were on aspirin. 71% of aspirin taking patients and 29% of non-aspirin taking patients had oral pH less than 6.5 (P < 0.01). Aspirin showed a significant association with low oral pH levels (odds ratio = 1.91, 95% CI 1.23-2.99, P < 0.01). 78 patients were given antacids and followed up for 4 weeks, 63 of them (81%) showed an improvement in oral pH and the improvement was marked in the group who had oral pH between 5.5-6.0 compared to the group who had oral pH between 6.0-6.5 (P = 0.03). The results show that aspirin therapy is associated with low oral pH and administration of an antacid with aspirin helps to increase the oral pH level.

The emergence of oral disease-modifying therapies in multiple sclerosis (MS) will have a significant impact on the evolving scenario of immunomodulatory treatments in MS where current therapies are all injectable. Reducing relapses in trials translates for individuals with MS into a therapeutic aim of stopping future events. Thus the possible absence of any perceived benefits to the individual together with the long disease course, variable outcome, and a younger age group affected in MS makes side effects the major issue. The use of disease-modifying therapies as a whole needs to be placed in the context of a widening therapeutic indication where the use of these therapies is being justified at an increasingly early stage and in pre-MS syndromes such as clinically isolated and radiologically isolated syndromes where no fixed disability is likely to have accumulated. The five oral therapies discussed (cladribine, fingolimod, laquinimod, BG-12, and teriflunomide) have just completed Phase III studies and some have just been licensed. New oral drugs for MS need to be placed within this evolving marketplace where ease of delivery together with efficacy and side effects needs to be balanced against the known issues but also the known long-term safety of standard injectables.

The analysis of the scientific literature devoted to organ and tissue changes of oral cavity at the chronic renal insufficiency (CRI)is made. The number of patients in an end-stage of CRI constantly increases and patients receiving renal replacement therapy including hemodialysis, peritoneal dialysis or renal transplantation will comprise an enlarging segment of the dental patient population. Owing to CRI and its treatment there is a set of changes of teeth and oral cavity fabrics which remain even in a end-stage. Renal replacement therapy can affect periodontal tissues including gingival hyperplasia in immune suppressed renal transplantation patients and increased levels of bacterial contamination, gingival inflammation, formation of calculus, and possible increased prevalence and severity of destructive periodontal diseases. Besides, the presence of undiagnosed periodontitis may have significant effects on the medical management of the patients in end-stage of CRI.

Background: No organized school oral health program is existent in India. Aim: The aim of this study is to test the feasibility and efficacy of an economical school oral health promotional intervention with educational and preventive components. Settings and Design: School oral health promotional intervention carried out in one of the randomly selected school and evaluated through short duration prospective model. Materials and Methods: A total of 100 children with an age range of 10-12 years with no previous history of dental intervention were enrolled. Interventions comprised of oral health education (delivered through lecture and demonstrations by an undergraduate dental student) and topical antibacterial therapy (fluoride varnish and povidone iodine). Outcomes consisted of Knowledge and practices (KAP) regarding oral health, clinical oral health related parameters such as plaque index (PI), gingival index (GI) and caries activity as per Modified Snyder's test. These were reported at baseline, 3 weeks and 6 months follow-up examination by a calibrated examiner. Statistical Analysis: McNemar Bowker's test, Student's t-test, Pearson Chi-square tests were used. Results: Highly significant (P < 0.001) improvements in KAP scores, PI scores, GI scores and caries activity were reported at 3 weeks and 6 months follow-up examination. Conclusion: This small economical school oral health program positively influenced oral health related practices and parameters of oral health such as oral cleanliness, gingival health and caries activity.

The present study aimed to assess the efficacy and indications of surgical laser therapy in the treatment of oral soft tissues benign tumors compared to classic surgery. A controlled clinical study was conducted in a group of 93 patients presenting various forms of oral soft tissues benign tumors. These patients were examined pre-and postoperatively and the oral benign tumors were measured linearly and photographed. The surgery of laser-assisted biopsy excision of oral benign tumors was carried out using a diode laser device of 980 nm. In patients who received surgical laser treatment, therapeutic doses of laser to biostimulate the operated area were administered on the first day after the surgery. The interventions of conventional excision of oral soft tissues benign tumors consisted in removing them using scalpel. In patients who have received therapeutic doses of laser for biostimulation of the operated area, a faster healing of wound surfaces and tumor bed was observed during the first days after surgery. Two weeks after the surgical treatment, good healing without scarring or discomfort in the area of excision was documented. Surgical treatment of oral soft tissues benign tumors with laser assisted postoperative therapy confirms the benefits of this surgical procedure. A faster healing process of the excision area due to laser biostimulation of low intensity has been observed in patients with surgical laser assisted treatment in the postoperative period.

The mouth and teeth play an important role in social interactions around the world. The way people deal with their teeth and mouth, however, is determined culturally. When oral healthcare projects are being carried out in developing countries, differing cultural worldviews can cause misunderstandings between oral healthcare providers and their patients. The oral healthcare volunteer often has to try to understand the local assumptions about teeth and oral hygiene first, before he or she can bring about a change of behaviour, increase therapy compliance and make the oral healthcare project sustainable. Anthropology can be helpful in this respect. In 2014, in a pilot project commissioned by the Dutch Dental Care Foundation, in which oral healthcare was provided in combination with anthropological research, an oral healthcare project in Kwale (Kenia) was evaluated. The study identified 6 primary themes that indicate the most important factors influencing the oral health of school children in Kwale. Research into the local culture by oral healthcare providers would appear to be an important prerequisite to meaningful work in developing countries.

The relationship between chronic hepatitis C virus infection (HCV) and oral lichen planus (OLP) is a current topic in the field of oral medicine. Many studies of this association have been made over time. The geographic variation of the hepatitis C prevalence proved to be an important factor influencing the statistical results of the studies analyzing the association of the oral plan lichen with the hepatitis C virus. Approaching this issue is not to be neglected. Treatment outcomes in patients with oral lichen planus associated with chronic hepatitis C virus are often unsatisfactory compared to patients suffering from idiopathic oral lichen planus. Also, the evolution of oral lesions is often fluctuating, with repeated periods of relapse according to the degree of liver function decompensation. Background therapy for liver disease itself may influence lichen planus lesions. Thus, during therapy with interferon and ribavirin oral lesions may appear or become acute. PMID:25553136

Oral contraception (OC) and postmenopausal hormone therapy (HT) can be used to alleviate menopausal symptoms. However, the risk of venous thrombosis (VT) associated with OC use in women over 50 years old has never been assessed and the two preparations have not been directly compared. To determine and compare the risk of VT associated with OC and HT use. From a large case-control study, 2550 women aged over 50 years old, 1082 patients with a first VT and 1468 controls, were included. Odds ratios (ORs) and 95% confidence intervals for VT were calculated for OC-users (164 patients and 54 controls) and HT-users (88 patients and 102 controls) compared with non-hormone users (823 patients and 1304 controls). OC-users had a 6.3-fold (4.6-9.8) increased risk of VT. This ranged from 5.4 (3.3-8.9) for preparations containing levonorgestrel to 10.2 (4.8-21.7) for desogestrel. The VT-risk associated with oral HT use was 4.0 (1.8-8.2) for conjugated equine estrogen combined with medroxyprogesterone acetate and 3.9 (1.5-10.7) for micronized estradiol combined with norethisterone acetate. Non-oral HT did not increase the risk of VT: OR 1.1 (0.6-1.8). Relative risk estimates were further increased in hormone users with factor V Leiden, prothrombin G20210A or blood group non-O and hormone users with a family history of VT. In this study, non-oral HT seemed to be the safest hormonal preparation in women over 50 years old. OC use increased the VT risk the most, especially in women with inherited thrombophilia or a family history of VT. © 2012 International Society on Thrombosis and Haemostasis.

Compare the effects of a combined contraceptive pill (OCP) in combination with myo-inositol (MI) on endocrine, metabolic, and clinical parameters in patients with polycystic ovary syndrome (PCOS). One hundred fifty-five patients with PCOS were enrolled in this prospective, open-label clinical study. Patients were assigned to receive oral treatment with OCP alone (estradiol (EE) 30 μg/gestodene 75 μg) or in combination with myo-inositol 4 g/die, for 12 months. OCP plus MI therapy resulted in a higher reduction of FG score compared with OCP alone therapy. The combined therapy (OCP plus MI) significantly decreased hyperinsulinaemia, by positively affecting the fasting insulin and glucose levels and homeostasis model assessment-insulin resistance parameters, while no significant changes were observed in the OCP group. Androgens serum levels decreased in both groups, but significantly more in the combined therapy group. The lipid profile was improved in the combined therapy group, by reducing low-density lipoprotein cholesterol levels and enhancing high-density lipoprotein cholesterol levels. Our data show that a combination of combined contraceptive pill and MI may be more effective in controlling endocrine, metabolic, and clinical profile in patients with PCOS than OCP alone, and may reduce insulin levels and insulin resistance. Hence, combined treatment may become a more effective long-term therapeutic choice for controlling PCOS symptoms.

Orbital cellulitis is conventionally managed by intravenous (i.v.) antibiotic therapy, followed by oral antibiotics once the infection shows signs of significant improvement. We report 4 years of experience using primary oral ciprofloxacin and clindamycin in cases of orbital cellulitis. Oral ciprofloxacin and clindamycin have a similar bioavailability to the i.v. preparations and provide an appropriate spectrum of antibiotic cover for the pathogens responsible for orbital cellulitis. A retrospective review was performed that identified all patients with orbital cellulitis and treated with primary oral antibiotic therapy admitted to the Manchester Royal Eye Hospital between March 2003 and March 2007. Age, stage of disease, surgical intervention, hospital duration, and complications were obtained. A comparison was made with patients admitted to our unit with orbital cellulitis and treated with primary i.v. antibiotics between March 2000 and March 2003. Nineteen patients were included in the review for the period March 2003 to March 2007, which comprised of 7 children and 12 adults. Five patients required surgical intervention. All patients responded to the oral regimen, 18 patients had no change to their oral antibiotic therapy. Mean hospital stay was 4.4 days. There were no complications. Empirical oral ciprofloxacin and clindamycin combination may be as safe and effective as i.v. therapy in the management of orbital cellulitis. Oral treatment can offer the advantages of rapid delivery of the first antibiotic dose, fewer interruptions in treatment, and simplified delivery of medication particularly in children.

To evaluate the long-term intervention effects of oral insulin on the development of type 1 diabetes and to assess the rate of progression to type 1 diabetes before and after oral insulin treatment was stopped in the Diabetes Prevention Trial-Type 1 (DPT-1). The follow-up included subjects who participated in the early intervention of oral insulin (1994-2003) to prevent or delay type 1 diabetes. A telephone survey was conducted in 2009 to determine whether diabetes had been diagnosed and, if not, an oral glucose tolerance test (OGTT), hemoglobin A1c (HbA1c), and autoantibody levels were obtained on all subjects who agreed to participate. Of 372 subjects randomized, 97 developed type 1 diabetes before follow-up; 75% of the remaining 275 subjects were contacted. In the interim, 77 subjects had been diagnosed with type 1 diabetes and 54 of the remainder have had an OGTT; 10 of these were diagnosed with type 1 diabetes, subsequently. Among individuals meeting the original criteria for insulin autoantibodies (IAAs) (≥80 nU/mL), the overall benefit of oral insulin remained significant (P=0.05). However, the hazard rate in this group increased (from 6.4% [95% CI 4.5-9.1] to 10.0% [7.1-14.1]) after cessation of therapy, which approximated the rate of individuals treated with placebo (10.2% [7.1-14.6]). Overall, the oral insulin treatment effect in individuals with confirmed IAA≥80 nU/mL appeared to be maintained with additional follow-up; however, once therapy stopped, the rate of developing diabetes in the oral insulin group increased to a rate similar to that in the placebo group.

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.

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.

Phenytoin is an anti-convulsant and anti-arrhythmic medication. Manufactured by various pharmaceutical companies with various brand names, phenytoin (PHT) is also known as Dilantain, Hydantoin or Phenytek in the United States; Dilantain or Remytoine in Canada; Epamin, Hidantoina in Mexico; and Fenidatoin or Fenitron or other names elsewhere in the world. Phenytoin (PHT) is especially useful for patients suffering from intractable oral and facial pain especially those who exhibit anger, stress, depression and irrational emotions commonly seen in the patients with oral and facial pain. When used properly, Phenytoin is also an effective anxiolysis drug in addition to its theraputic effects on pain and can be used alone or, even better, if combined with other compatible sedatives. Phenytoin is particularly valuable when combined with acupuncture for patients with trigeminal neuralgia, glossopharyneal neuralgia, Bell's palsy, and some other facial paralysis and pain. It also has an advantage of keeping the patient relatively lucid after treatment. Either PHT or acupuncture alone can benefit patients but the success of treatment outcome may be limited. We found by combining both acupuncture and PHT with Selective Drug Uptake Enhancement by stimulating middle finger at the first segment of ventral (palmar) and lateral surfaces, as well as prescribing PHT with the dosage predetermined for each patient by Bi-Digital O-Ring Test (BDORT), the treatment outcome was much better resulted with less recurrence and intensity of pain during episodes of attack. Patients with Bell's palsy were most benefited by acupuncture therapy that could completely get rid of the illness.

The purpose of this study was to assess patient adherence to an oral preventive measures (OPM) protocol and its impact on cancer treatment outcomes. A retrospective cohort of oral cancer of 133 patients submitted to radiotherapy (RT) was selected, excluding those with metastasis. Patients were grouped according to their local tumor response after finishing RT (favorable or unfavorable) and adherence to an OPM (none, ≤6 months, and >6 months). OPM included education and counseling about adverse effects, elimination of infection foci, restorative procedures, fluoride therapy, oral rehydration, and maintenance and supervision of oral hygiene throughout treatment. Clinical and pathological characteristics were recorded, and patient outcomes (frequency of adverse effects, RT interruption, and overall survival) were analyzed. Patients with higher adherence to the OPM had greater occurrence of RT interruption as a consequence of symptoms (p = 0.01); however, these patients were more likely to complete the established RT protocol (p = 0.02). Overall survival (p = 0.01) was higher in the group with higher adherence. This study suggests that the implementation of oral preventive measures may contribute to improving the prognosis of squamous cell carcinoma (SCC) treatment by reducing the negative impact of oral complications.

2014-01-01

With increasing numbers of antibiotic-resistant pathogens all over the world there is a pressing need for strategies that are capable of inactivating biofilm-state pathogens with less potential of developing resistances in pathogens. Antimicrobial strategies of that kind are especially needed in dentistry in order to avoid the usage of antibiotics for treatment of periodontal, endodontic or mucosal topical infections caused by bacterial or yeast biofilms. One possible option could be the antimicrobial photodynamic therapy (aPDT), whereby the lethal effect of aPDT is based on the principle that visible light activates a photosensitizer (PS), leading to the formation of reactive oxygen species, e.g., singlet oxygen, which induce phototoxicity immediately during illumination. Many compounds have been described as potential PS for aPDT against bacterial and yeast biofilms so far, but conflicting results have been reported. Therefore, the aim of the present review is to outline the actual state of the art regarding the potential of aPDT for inactivation of biofilms formed in vitro with a main focus on those formed by oral key pathogens and structured regarding the distinct types of PS.

Non-specific infections of the oral mucosa are rare; however, they may present during HIV infection in the form of gingivo-periodontal lesions. In some of these Candida albicans may play a role in the pathogenesis. Sexually transmitted bacterial infections such as gonorrhoea and syphilis are frequently associated with HIV infection. Since penicillin resistance is frequent in gonorrhoea, the cephalosporines are mainly used for treatment. Syphilis increases the risk for transmission of HIV. Lues maligna with oral manifestations has been described. For this, penicillin G is the therapy of choice. Tuberculosis, characterized by multitherapy resistance, is associated with HIV infections world-wide; oral manifestations are rare. Oral candidiasis during HIV infection is often characterized by therapy resistance against fluconazole and a shift in species, with Candida glabrata and Candida krusei as the emerging species. The azoles are still the mainstay of therapy, particularly fluconazole. Herpes simplex (HSV) infections run an atypical course during HIV disease; resistance against acyclovir is a clinical problem. The association of HSV infection with erythema exudativum multiforme has been clearly shown. Oral hairy leukoplakia caused by Epstein Barr virus is a characteristic infection during immunosuppression. Cytomegalovirus infection is also observed in immunodeficient patients. Cases of ganciclovir resistance have been described. Human herpes virus 8 (HHV 8) is associated with Kaposi's sarcoma. Therapeutic trials have focussed on the inhibition of HHV 8 replication. Over 100 different genotypes of human papillomaviruses are known; some can cause infections of the oral mucosa. Characteristic lesions caused by different HPV genotypes are verruca vulgaris, condyloma acuminatum and focal epithelial hyperplasia.

Sweden is the only country in which oral high dose vitamin B12 has gained widespread use in the treatment of deficiency states. The aim of the study was to describe prescribing patterns and sales statistics of vitamin B12 tablets and injections in Sweden 1990-2000.Design, setting, and sources: Official statistics of cobalamin prescriptions and sales were used. The use of vitamin B12 increased in Sweden 1990-2000, mainly because of an increase in the use of oral high dose vitamin B12 therapy. The experience, in statistical terms a "total investigation", comprised 1,000,000 patient years for tablets and 750,000 patient years for injections. During 2000, 13% of residents aged 70 and over were treated with vitamin B12, two of three with the tablet preparation. Most patients in Sweden requiring vitamin B12 therapy have transferred from parenteral to oral high dose vitamin B12 since 1964, when the oral preparation was introduced. The findings suggest that many patients in other post-industrial societies may also be suitable for oral vitamin B12 treatment.

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{sup 2}; CDDP, total 100-150 mg/m{sup 2}) and daily concurrent radiation therapy (total, 40-60 Gy) for 4-6 weeks.more » 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

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.

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 (P<0.05). No changes from baseline were detected following administration of placebo and no treatment (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.

Pregnant women demonstrate increases in gingivitis despite similar plaque levels to non-pregnant counterparts. 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.

A twice-weekly oral and perioral examination was provided to 120 patients receiving antineoplastic therapy. Sixty patients were monitored while following the traditional hospital oral care protocol (chlorhexidine, hydrogen peroxide, sodium bicarbonate, thymol glycol, benzocaine mouthrinse, and nystatin). The mouth care protocol was then changed (experimental protocol = chlorhexidine, benzocaine lozenges, amphotericin B lozenges), and patients were monitored until the sample size matched that of the hospital mouth care regime. There was a statistically significant reduction in oral complications upon introduction and maintenance of the experimental protocol.

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

Oral lichen planus.

Lichen planus is an inflammatory mucocutaneous disease that can affect the skin, hair, nails, and mucosal surfaces. Mucosal sites of involvement include oral, genital, ocular, otic, esophageal, and, less commonly, bladder, nasal, laryngeal, and anal surfaces. Oral lichen planus is a mucosal variant of lichen planus, which tends to affect women more often than men, with a typically more chronic course and potential for significant morbidity. Treatment can be challenging, and there is potentially a low risk of malignant transformation; however, therapeutic benefits can be obtained with various topical and systemic medications. Clinical monitoring is recommended to ensure symptomatic control. Increasing awareness and recognition of this entity have continued to fuel advances in therapy and in our understanding of the disease. Copyright © 2016 Elsevier Inc. All rights reserved.

Intravenous cyclosporine therapy followed by oral cyclosporine therapy reduce the need for urgent surgery in steroid-refractory inflammatory bowel disease (IBD). Our objective is to report short- and long-term results of cyclosporine therapy in IBD patients. Thirteen patients with steroid-refractory IBD, seven patients with ulcerative colitis (UC), and six patients with Crohn's disease (CD) were treated with intravenous cyclosporine (4 mg/kg/day) for a mean period of 11.4+/-2.8 days (range, 4-15 days). Subsequently the patients were started on oral cyclosporine (8 mg/kg/day) and followed for a mean of 10.3+/-10 months (range, 1-30 months). Twelve patients responded to intravenous cyclosporine therapy. One patient with UC developed sepsis on the fourth day of intravenous cyclosporine therapy and needed urgent colectomy. Nine of 12 initial responders (6 patients with UC and 3 patients with CD) relapsed during follow-up despite oral cyclosporine and underwent elective surgery. One patient with CD relapsed 3 months after discontinuation of oral cyclosporine. Only two patients with CD are in long-term remission. There were no long-term side effects in any of the 13 treated patients. In conclusion, intravenous cyclosporine was effective in inducing remission or significant improvement in 12 of 13 patients with steroid-refractory IBD. However, with subsequent oral cyclosporine the remission could be maintained only for a short while. Each of the six patients with UC needed colectomy and three of the five patients with CD had intestinal resection within 12 months despite oral cyclosporine therapy.

Objective To compare the safety and efficacy of intravenous (IV) ciprofloxacin plus IV metronidazole (CIP+MET) with that of IV piperacillin/tazobactam (PIP/TAZO) in adults with complicated intraabdominal infections, and to compare the efficacy of sequential IV-to-oral CIP+MET therapy with that of the IV CIP-only regimen. Summary Background Data Treatment of intraabdominal infections remains a challenge, mainly because of their polymicrobial etiology and attendant death and complications. Antimicrobial regimens using sequential IV-to-oral therapy may reduce the length of hospital stay. Methods In this multicenter, randomized, double-blind trial involving 459 patients, clinically improved IV-treated patients were switched to oral therapy after 48 hours. Overall clinical response was the primary efficacy measurement. Results A total of 282 patients (151 CIP+MET, 131 PIP/TAZO) were valid for efficacy. Of these patients, 64% CIP+MET and 57% PIP/TAZO patients were considered candidates for oral therapy. Patients had a mean APACHE II score of 9.6. The most common diagnoses were appendicitis (33%), other intraabdominal infection (29%), and abscess (25%). Overall clinical resolution rates were statistically superior for CIP+MET (74%) compared with PIP/TAZO (63%). Corresponding rates in the subgroup suitable for oral therapy were 85% for CIP+MET and 70% for PIP/TAZO. Postsurgical wound infection rates were significantly lower in CIP+MET (11%) versus PIP/TAZO patients (19%). Mean length of stay was 14 days for CIP+MET and 17 days for PIP/TAZO patients. Conclusion CIP+MET, initially administered IV and followed by CIP+MET oral therapy, was clinically more effective than IV PIP/TAZO for the treatment of patients with complicated intraabdominal infections.

The combined effect of terpinen-4-ol, the main component of tea tree oil, and capric acid against mycelial growth of Candida albicans and murine oral candidiasis was evaluated in vitro and in vivo. Mycelial growth of C. albicans was estimated by the Cristal violet method. Combination of these compounds revealed a potent synergistic inhibition of growth. Therapeutic efficacy of the combination was evaluated microbiologically in murine oral candidiasis, and its application of the compounds clearly demonstrated therapeutic activity. Based on these results, the combined agent of terpinen-4-ol and capric acid was discussed as a possible candidate for oral candidiasis therapy.

Oral drug delivery in personalized medicine: unmet needs and novel approaches.

Wening, Klaus; Breitkreutz, Jörg

2011-02-14

Increasing knowledge into personalized medicine has demonstrated the need for individual dosing. Drug dosage forms are urgently needed enabling an individual therapy, especially for oral drug delivery. This review is focusing on approaches for solid and liquid oral dosage forms for individual dosing. The proposed dosage forms and devices may be distinguished into assembling and partition concepts and have been categorized regarding their applicability, costs, dose flexibility and potential benefits. Opportunities, challenges and further unmet needs are elaborated and critically discussed. Liquid dosage forms can be accurately dosed by novel dropping tubes or oral syringes, but less precisely by dosing spoons and cups. Breaking scored tablets into fragments show major risks such as inaccurate dosing, formation of potent dust and stability issues of the residual segments. Novel approaches are proposed for solid dosage forms enabling a flexible and appropriate therapy such as various dispensers for multiparticulate drug formulations. However, most of the proposals still have to prove their applicability in practice. Promising concepts are the solid dosage pen and drug-loaded oral films which can be cut in individual sections enabling freely selectable doses. Further research and development are required for novel dosage forms and medical devices appropriate for individualized therapy. Copyright © 2010 Elsevier B.V. All rights reserved.

Phenytoin Induced Erythema Multiforme after Cranial Radiation Therapy

The prophylactic use of phenytoin during and after brain surgery and cranial irradiation is a common measure in brain tumor therapy. Phenytoin has been associated with variety of adverse skin reactions including urticaria, erythroderma, erythema multiforme (EM), Stevens-Johnson syndrome, and toxic epidermal necrolysis. EM associated with phenytoin and cranial radiation therapy (EMPACT) is a rare specific entity among patients with brain tumors receiving radiation therapy while on prophylactic anti-convulsive therapy. Herein we report a 41-year-old female patient with left temporal glial tumor who underwent surgery and then received whole brain radiation therapy and chemotherapy. After 24 days of continous prophylactic phenytoin therapy the patient developed minor skin reactions and 2 days later the patient returned with generalized erythamatous and itchy maculopapuler rash involving neck, chest, face, trunk, extremities. There was significant periorbital and perioral edema. Painful mucosal lesions consisting of oral and platal erosions also occurred and prevented oral intake significantly. Phenytoin was discontinued gradually. Systemic admistration of corticosteroids combined with topical usage of steroids for oral lesions resulted in complete resolution of eruptions in 3 weeks. All cutaneous lesions in patients with phenytoin usage with the radiotherapy must be evoluated with suspicion for EM. PMID:26361537

Photodynamic therapy (PDT) with photosensitizer is one of the promising modalities for cancer treatment. For clinical use of PDT, screening process should be preceded to enhance sensitivity to PDT. Thus, we investigated a molecular biomarker to determine the sensitivity to pheophorbide a (Pa)-PDT in immortalized human oral keratinocytes (IHOK) and oral squamous cell carcinoma (OSCC) cell lines. Two IHOK and several OSCC cell lines were used. After Pa-PDT, cell viability was reduced by more than 50%, and reactive oxygen species were generated in IHOK and OSCC cell lines. Additionally, apoptosis occurred in PDT-treated cells. IHOK(S) and IHOK(P), the two IHOK cell lines derived from the same source, showed a difference in cytotoxicity after Pa-PDT. To explain this difference in cytotoxicity, we looked at the expression of Wnt signaling-related genes in these two cell lines, for the morphology of IHOK(S) which was spindle like and elongated and distinct from IHOK(P) and the parent cell. Among the relevant genes, runt-related transcription factor 3 (RUNX3), an apoptosis-related gene, was selected as a potential marker that confers sensitivity to PDT. We found that the cytotoxicity by Pa-PDT was proportional to RUNX3 expression in OSCC cell lines. Additionally, knockdown of RUNX3 expression reduced cytotoxicity by Pa-PDT, suggesting that RUNX3 might be a biomarker to determine sensitivity to Pa-PDT. This was the first study to find a new target molecule that enhances Pa-PDT effects in IHOK and OSCC cell lines. Hence, the development of a PDT-dependent biomarker could provide a novel approach to improve the effects of PDT on oral precancerous and cancerous lesions.

Oral and dental infections with anaerobic bacteria: clinical features, predominant pathogens, and treatment.

Microbial populations colonizing the teeth are a major source of pathogens responsible for oral and dental infections, including periodontal diseases, gingivitis, pericoronitis, endodontitis, peri-implantitis, and postextraction infections. Each entity has distinct clinical and microbial features. Bacterial species associated with oral infections include Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Bacteroides forsythus, Campylobacter rectus, Eubacterium species, Fusobacterium nucleatum, Eikenella corrodens, and Peptostreptococcus micros. Treponema pallidum-related spirochetes have been associated with acute necrotizing ulcerative gingivitis. Porphyromonas endodontalis appears to be specifically related to endodontic infections. Oral infections in medically compromised patients, including those with AIDS, are associated with similar species and are usually complicated by superinfection with enteric and Candida species. Isolation of species causing oral infections requires the collection of appropriate samples and the use of strictly anaerobic techniques. Rapid selective culture, immunofluorescence, and DNA probe methods have been developed for the identification of these oral species. The varied measures required in the management of oral and dental infections may include antimicrobial therapy. Accurate microbiological diagnosis, including antibiotic susceptibility testing, is indicated for cases that do not respond to therapy.

Oral anticoagulants (OAC) are commonly used as a life-long therapy in prevention of systemic embolism in patients with atrial fibrillation, valvular heart disease and prosthetic hart valves and in the primary and secondary prevention of venous thromboembolism. They are also used for the prevention of thromboembolic events in patients with acute myocardial infarction and with angina pectoris, in patients with biological hart valves and after some types of orthopaedics surgery. The International Normalized Ratio (INR) is used to evaluate the efficacy of anti-coagulant therapy. The risk of thromboembolic and haemorrhagic complications increases when the INR is out of the therapeutic range. The aim of this study was to present information about the factors influencing activity of oral anticoagulants and interactions between oral anticoagulants and drugs or food. The effect of oral anticoagulants is influenced by genetic and environmental factors such as: medicines, food, diseases and pre-existing conditions. A common mutation in the gene coding for the cytochrome P450 (CYP2C9), with one or more combinations of its polymorphisms, is responsible for the reduced warfarin requirements or for the resistance to warfarin. A mutation in the factor IX is responsible for the risk of bleeding during OAC therapy without excessive prolongation of the prothrombin time (PT). Drugs, herbs and multivitamin supplements can alter the absorption, pharmacokinetics or pharmakodynamics of OAC. Nonsteroid anti-inflammatory drugs and paracetamol in combination with OAC seem to be the most dangerous because they are available without prescription and are used without medical consultation. Patients on OAC therapy are sensitive to changing dietary intake of vitamin K, which is supplied from phylloquinones in plants or from vitamin K-containing medicines. The effect of OAC can be influenced by other existing factors like: fever, diarrhoea, alcohol abuse or physical hyperactivity. Some malignancies

Pyropheophorbide-a-hexyl ether (HPPH) is a new photosensitizer for use with photodynamic therapy (PDT) that has shown promise in laboratory animals. PDT, using this drug, is being used to treat canine patients afflicted with hemangiopericytoma and oral squamous cell carcinoma (SCC) at the University of Missouri-Columbia College of Veterinary Medicine. To date, 11 dogs with hemangiopericytoma and 5 dogs with oral SCC have been treated using a combination of surgery and PDT. Thus far, there have been no serious complications attributable to the treatment. Two dogs have had recurrences of the hemangiopericytoma and there have been no recurrences of SCC with a median follow time of 5 months. Both recurrent hemangiopericytomas were in patients with large tumors that had previous surgery. This study is ongoing and no conclusions have been reached; however several observations are noted. It appears that PDT using HPPH is safe is dogs, and may decrease the recurrence rate of Hemangiopericytomas. In dogs with oral SCC, the treatment is effective is causing necrosis and sloughing of the tumor tissue, and recurrences have not been noted on follow-ups up to 6 months.

The aim of this research is to determine efficacy and safety of repaglinide alone and in combination with metformin in Chinese subjects with type 2 diabetes naive to oral antidiabetes therapy. A 16-week, open-label, randomized, active-controlled, parallel-group trial was carried out. Subjects were randomized (1:1) to repaglinide 1 mg t.i.d. (maximum dose, 4 mg t.i.d.) or repaglinide plus metformin 1 mg/500 mg t.i.d. (maximum dose, 4 mg/500 mg t.i.d.). Eligible subjects (18 - 75 years old) had type 2 diabetes, A1C > 8.5%, BMI ≤ 35 kg/m(2), and were naive to oral antidiabetes agents. The primary outcome was A1C reduction. Secondary end points included fasting plasma glucose (FPG), 2-h postprandial glucose (PPG), and 7-point plasma glucose. Baseline characteristics (repaglinide/metformin, n = 218; repaglinide-only, n = 214) were similar between groups. Mean A1C reduction (± SD) was 4.51 ± 1.64% (combination) and 4.05 ± 1.59% (monotherapy). Estimated mean treatment difference for repaglinide/metformin versus repaglinide-only was -0.30% (95% CI -0.49 to -0.11; p < 0.01). Combination treatment demonstrated significant improvements versus monotherapy in FPG, 7-point plasma glucose, and lunchtime and dinnertime 2-h PPG (all p < 0.05). Hypoglycemia rates were 2.04 (combination) versus 1.35 (monotherapy) events/subject-year (p = 0.058). Adverse events were comparable between groups. Repaglinide plus metformin and repaglinide alone provided significant improvements in glycemic control and were well tolerated in Chinese patients naive to treatment with oral antidiabetes agents. Combination therapy with repaglinide plus metformin showed superiority to repaglinide monotherapy in this population. Limitations of this study are that subjects were newly diagnosed and had high mean baseline A1C, which may affect generalizability of results.

Several diagnostic and therapeutic methods are based on the optical properties of lasers. In therapeutic applications, laser light is absorbed in a specific manner, whereas light is scattered, reflected, or transmitted from different structures. Improvements in laser technology allow new procedures and broaden the scope of applications for both diagnosis and therapy. The focus of laser application in Oral Medicine diagnosis should be early detection of oral squamous cell carcinoma. Novel modalities for the detection of oral malignancy are urgently needed, while others must be continuously improved. Optical coherence tomography and laser-induced fluorescence spectroscopy are currently being studied. In addition to diagnosis of non-malignant lesions, laser therapy has been used based upon the biological reactions and molecular wound healing mechanisms as an alternative for the treatment of a variety of oral soft tissue lesions. The aim of the present article is to review current knowledge and future perspectives of lasers in Oral Medicine.

Preoperative bowel preparation with or without oral antibiotics is controversial in terms of postoperative surgical site infections. This study aimed to evaluate the efficacy of oral antibiotics as adjunct therapy to systemic antibiotics with mechanical bowel preparation for preventing surgical site infections in clean contaminated, contaminated, and dirty colorectal procedures. This was a single-center, prospective randomized study. This study was conducted at the General Surgery Department at Jinling Hospital, Nanjing University, China, from July 15, 2014 to January 20, 2016. Patients aged ≥18 years scheduled for abdominal surgery with clean-contaminated, contaminated, and dirty wounds were selected. Patients were randomly assigned to receive preoperative mechanical bowel preparation or mechanical bowel preparation with oral antibiotics. The primary outcome was the rate of surgical site infections. The secondary outcomes were extra-abdominal complications, duration of postoperative ileus, and readmission rate. Ninety-five patients were allocated to each group. Eight and 26 surgical site infections (8.42% vs 27.3 %, p = 0.004) occurred in the mechanical bowel preparation with oral antibiotics and mechanical bowel preparation groups. Thirteen extra-abdominal complications were reported: 6 in the mechanical bowel preparation with oral antibiotics group and 7 in the mechanical bowel preparation group (6.3% vs 7.3%, p = 0.77). Postoperative ileus duration did not differ between groups (p = 0.23). There were 4 readmissions in the mechanical bowel preparation group and none in the mechanical bowel preparation with oral antibiotics group (p = 0.04). On multivariable analysis, blood loss ≥500 mL (OR, 5.1; 95% CI, 1.27-20.4; p = 0.02), ASA score ≥3 (OR, 3.9; 95% CI, 1.2-12.5; p = 0.01), contaminated types (OR, 3.6; 95% CI, 1.5-8.6; p = 0.01), and administration of preoperative oral antibiotics (OR, 0.20; 95% CI, 0.06-0.60; p = 0.005) independently affected the

Sharks possess a variety of pathogenic bacteria in their oral cavity that may potentially be transferred into humans during a bite. The aim of the presented study focused on the identification of the bacteria present in the mouths of live blacktip sharks, Carcharhinus limbatus, and the extent that these bacteria possess multi-drug resistance. Swabs were taken from the oral cavity of nineteen live blacktip sharks, which were subsequently released. The average fork length was 146 cm (±11), suggesting the blacktip sharks were mature adults at least 8 years old. All swabs underwent standard microbiological work-up with identification of organisms and reporting of antibiotic susceptibilities using an automated microbiology system. The oral samples revealed an average of 2.72 (±1.4) bacterial isolates per shark. Gram-negative bacteria, making up 61% of all bacterial isolates, were significantly (p<0.001) more common than gram-positive bacteria (39%). The most common organisms were Vibrio spp. (28%), various coagulase-negative Staphylococcus spp. (16%), and Pasteurella spp. (12%). The overall resistance rate was 12% for all antibiotics tested with nearly 43% of bacteria resistant to at least one antibiotic. Multi-drug resistance was seen in 4% of bacteria. No association between shark gender or fork length with bacterial density or antibiotic resistance was observed. Antibiotics with the highest overall susceptibility rates included fluoroquinolones, 3rd generation cephalosporins and sulfamethoxazole/trimethoprim. Recommended empiric antimicrobial therapy for adult blacktip shark bites should encompass either a fluoroquinolone or combination of a 3rd generation cephalosporin plus doxycycline. PMID:25110948

Background This study investigated the effect of oral dimercapto succinic acid (DMSA) therapy for children with autism spectrum disorders ages 3-8 years. Methods Phase 1 involved 65 children who received one round of DMSA (3 days). Participants who had high urinary excretion of toxic metals were selected to continue on to phase 2. In phase 2, 49 participants were randomly assigned in a double-blind design to receive an additional 6 rounds of either DMSA or placebo. Results DMSA greatly increased the excretion of lead, substantially increased excretion of tin and bismuth, and somewhat increased the excretion of thallium, mercury, antimony, and tungsten. There was some increase in urinary excretion of essential minerals, especially potassium and chromium. The Phase 1 single round of DMSA led to a dramatic normalization of RBC glutathione in almost all cases, and greatly improved abnormal platelet counts, suggesting a significant decrease in inflammation. Conclusion Overall, DMSA therapy seems to be reasonably safe, effective in removing several toxic metals (especially lead), dramatically effective in normalizing RBC glutathione, and effective in normalizing platelet counts. Only 1 round (3 days) was sufficient to improve glutathione and platelets. Additional rounds increased excretion of toxic metals. PMID:19852789

Background Disodium ethylene diamine tetraacetic acid (EDTA) reduced adverse cardiac outcomes in a factorial trial also testing oral vitamins. Objective This report describes the intent-to-treat comparison of the 4 factorial groups overall and in patients with diabetes. Methods Double-blind placebo-controlled 2 × 2 factorial multicenter randomized trial of 1708 post-MI patients ≥ 50 years and creatinine ≤2.0 mg/dL randomized to receive 40 EDTA chelation or placebo infusions plus 6 caplets daily of a 28-component multivitaminmultimineral mixture or placebo. Primary endpoint was a composite of total mortality, MI, stroke, coronary revascularization, or hospitalization for angina. Results Median age was 65 years, 18% female, 94% Caucasian, 37% diabetic, 83% prior coronary revascularization, and 73% on statins. Five-year Kaplan-Meier estimates for the primary endpoint in the chelation + high-dose vitamin group was 31.9%, in the chelation + placebo vitamin group 33.7%, in the placebo infusion + active vitamin group 36.6%, and in the placebo infusions + placebo vitamin group 40.2 %. The reduction in primary endpoint by double active treatment compared with double placebo was significant (HR 0.74, 95% CI (0.57,0.95); p=0.016). In patients with diabetes, the primary endpoint reduction of double active compared with double placebo was more pronounced (HR 0.49, 95% CI (0.33,0.75), p<0.001). Conclusions In stable post- MI patients on evidence-based medical therapy, the combination of oral high-dose vitamins and chelation therapy compared with double placebo reduced clinically important cardiovascular events to an extent that was both statistically significant and of potential clinical relevance.

Little is known about the impact of different stages of implant therapy on oral health-related quality of life (OHRQoL). The aim of this study was to assess OHRQoL before, during, and after completion of prosthodontic implant therapy by patients and treating physicians, who were predicted to evaluate OHRQoL in different ways. Over a period of six months, 16 randomly selected patients were assessed for OHRQoL with a German version of the Oral Health Impact Profile (OHIP-G, range 0-220). Patients assessed themselves before surgery, during the period of complete osseointegration, and after prosthodontic treatments. Additionally, physicians assessed OHRQoL and OHIP subscales with a visual analogue scale. Patients reported significant changes in median OHIP scores (preoperative: 76.5; healing period: 84.3; postoperative: 29.5; p<0.01), as did physicians (preoperative: 7.1; postoperative: 2; p<0.01). The most prevalent patient-reported problem was "worried" (subscale: psychological discomfort), whereas the subscale "functional limitation" was identified most frequently by physicians. Preoperative, intermediate, and post-treatment assessments of OHRQoL exhibited significantly different OHIP scores. In contrast to the physicians' assessments, the most unfavourable OHIP scores were reported by patients during the healing period, while the psychological dissatisfaction OHIP subscale represented the most important patient factor.

Oral cancer is one of the most commonly occurring malignant tumors in the head and neck regions with high incident rate and mortality rate in the developed countries than in the developing countries. Generally, the survival rate of cancer patients may increase when diagnosed at early stage, followed by prompt treatment and therapy. Recently, cancer diagnosis and therapy design for a specific cancer patient have been performed with the advanced computer-aided techniques. The responses of the cancer therapy could be continuously monitored to ensure the effectiveness of the treatment process that hardly requires diagnostic result as quick as possible to improve the quality and patient care. This paper gives an overview of oral cancer occurrence, different types, and various diagnostic techniques. In addition, a brief introduction is given to various stages of immunoanalysis including tissue image preparation, whole slide imaging, and microscopic image analysis. PMID:29284926

Will novel oral formulations change the management of inflammatory bowel disease?

Nielsen, Ole Haagen; Seidelin, Jakob Benedict; Ainsworth, Mark; Coskun, Mehmet

2016-06-01

The traditional management of inflammatory bowel disease (IBD) with sulphasalazine/5-aminosalicylic acid, glucocorticoids and immunomodulators (i.e., thiopurines and methotrexate) was nearly two decades ago extended with intravenously or subcutaneously administered biologics (i.e., tumor necrosis factor inhibitors and later gut-selective integrin antagonists). However, recently, orally administered treatments with simple, well-characterized, and stable structures consisting of either small molecules or anti-sense therapy have been devised. This review discusses the current approaches with promising new oral drugs with distinct modes of action, including: the Janus kinase inhibitors (i.e., tofacitinib, filgotinib and peficitinib); the immunomodulatory drug (laquinimod); a small α4 antagonist (AJM300); agonists for sphingosine-phosphate receptors (i.e., ozanimod, APD334, and amiselimod), as well as anti-sense therapy (mongersen) targeting SMAD7, drugs which directly target intracellular pathways of relevance for intestinal inflammation. A new avenue using easily administered oral therapies for the management of IBD is being introduced. While their place in the clinical armamentarium remains to be proven, it is likely that many of these drugs will find their place in the treatment algorithm of IBD in the next few years. Thus, we will face times in which IBD therapy will be based on significantly more tablets than prescribed today.

Anticoagulant and Antiplatelet Therapy in Patients with Atrial Fibrillation and Coronary Artery Disease

Mischke, Karl; Knackstedt, Christian; Marx, Nikolaus

2012-01-01

Anticoagulation represents the mainstay of therapy for most patients with atrial fibrillation. Patients on oral anticoagulation often require concomitant antiplatelet therapy, mostly because of coronary artery disease. After coronary stent implantation, dual antiplatelet therapy is necessary. However, the combination of oral anticoagulation and antiplatelet therapy increases the bleeding risk. Risk scores such as the CHA2DS2-Vasc score and the HAS-BLED score help to identify both bleeding and stroke risk in individual patients. The guidelines of the European Society of Cardiology provide a rather detailed recommendation for patients on oral anticoagulation after coronary stent implantation. However, robust evidence is lacking for some of the recommendations, and especially for new oral anticoagulants and new antiplatelets few or no data are available. This review addresses some of the critical points of the guidelines and discusses potential advantages of new anticoagulants in patients with atrial fibrillation after stent implantation.

Dysphagia in adults arises from a range of causes including acquired neurological disorders and some cancers. Previous research has suggested that treatment using neuromuscular electrical stimulation (NMES) when used in conjunction with conventional therapy is effective. This review describes the recent literature and a small prospective case series carried out in the United Kingdom. This study contributed to support National Institute of Clinical Excellence (NICE) guidance for clinicians who wish to include NMES in a rehabilitation programme for dysphagic patients, specifically with reference to safety and the impact on swallowing function of this intervention. In 2014, the UK NICE issued guidelines enabling UK therapists to trial the use of NMES, but the guidelines also sought additional evidence on the impact on swallowing function of NMES and the incidence of side effects. This small prospective case series investigated both of these aspects with a group of patients with dysphagia of neurological origin who had not achieved adequate swallowing function with traditional therapy alone. This study recruited 10 adult patients with dysphagia of neurological origin. All had previously received traditional swallowing therapy for at least 6 months but only achieved a Functional Oral Intake Scale of 4 or less (a scale for amounts and types of oral intake). The total study period was 10 weeks for each subject comprising 5 weeks of traditional therapy delivered three times a week followed by 5 weeks of NMES concurrent with traditional therapy (NMES + traditional therapy) delivered three times a week using the VitalStim stimulator (VitalStim Therapy, UK). In addition, the Quality of Life in Swallowing and Eating Assessment Tool 10 (quality of life scales) were determined to allow comparison between studies. Nine subjects achieved an improvement in swallowing function after NMES + traditional therapy was measured using the Functional Oral Intake Scale, giving a

Background Patients with osteoporosis who receive tooth extractions are typically on either oral bisphosphonate or parathyroid hormone (PTH) therapy. Currently, the consequence of these therapies on hard- and soft-tissue healing in the oral cavity is not clearly defined. The aim of this study is to determine the differences in the therapeutic effect on tooth-extraction wound healing between bisphosphonate and PTH therapies. Methods Maxillary second molars were extracted in Sprague Dawley rats (n = 30), and either bisphosphonate (zoledronate [Zol]), PTH, or saline (vehicle control [VC]) was administered for 10 days (n = 10 per group). Hard-tissue healing was evaluated by microcomputed tomography and histomorphometric analyses. Collagen, blood vessels, inflammatory cell infiltration, and cathepsin K expression were assessed in soft tissue using immunohistochemistry, quantitative polymerase chain reaction, and immunoblotting. Results Both therapies significantly increased bone fill and suppressed vertical bone loss. However, considerably more devital bone was observed in the sockets of rats on Zol versus VC. Although Zol increased the numbers of blood vessels, the total blood vessel area in soft tissue was significantly smaller than in VC. PTH therapy increased osteoblastic bone formation and suppressed osteoclasts. PTH therapy promoted soft-tissue maturation by suppressing inflammation and stimulating collagen deposition. Conclusion Zoledronate therapy deters whereas PTH therapy promotes hard- and soft-tissue healing in the oral cavity, and both therapies prevent vertical bone loss. PMID:23688101

We report on an edentulous patient suffering from drug-induced tardive dyskinesia (TD) and oral parafunction (OP) rehabilitated with implant-supported screw-retained prostheses. The frequency and intensity of the movements were high, and no pharmacological intervention was possible. Moreover, the patient refused night-time splint therapy. A series of implant and prosthetic failures were experienced. Implant failures were all in the maxilla and stopped when a rigid titanium structure was placed to connect implants. Ad hoc designed studies are desirable to elucidate the mutual influence between oral movement disorders and implant-supported rehabilitation.

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

The aim of this study was to evaluate efficacy and safety of continuous, low dose of oral, metronomic chemotherapy as maintenance therapy in patients with advanced ovarian carcinoma after complete clinical response to platinum and paclitaxel chemotherapy. In this nonrandomized study, patients older than 18 years, with Eastern Cooperative Oncology Group performance status less than 2, with advanced ovarian carcinoma after complete clinical response to platinum and paclitaxel chemotherapy were enrolled in 2 arms--arm A (maintenance arm), treated with continuous low-dose oral cyclophosphamide 50 mg and methotrexate 2.5 mg, and arm B (observation arm). Both arms were followed up for progression-free survival and toxicity. Thirty patients were accrued in each arm from January 2009 to December 2010 in Ain Shams University Hospitals, where they received the treatment and followed up for disease progression and toxicity. Patients had a median age of 53 years in maintenance arm and 52.5 years in the observational arm, respectively. Over 80% had papillary serous adenocarcinoma, and over 40% of them had a stage IV disease in both arms. After median follow-up of 27 months, patients achieved median progression-free survival of 18 months in maintenance arm (A) and 15.5 months in observational arm (B), respectively. Toxicity profile was excellent with no grade 3 or 4 toxicity reported. Current study may provide an evidence of efficacy and tolerability of continuous low-dose oral cyclophosphamide and methotrexate as a maintenance therapy in patients with advanced ovarian carcinoma after complete clinical response to platinum and paclitaxel chemotherapy.

Bad habits result in altered functions which with time can cause anomalies of the orofacial morphology. To solve these problems, orthodontic treatment can be supported by myofunctional therapy in order to recover the normal functionality of the oral muscles. The aim of this study is to assess the need to treat patients with neuromuscular disorders, from both the occlusion and the muscles condition approach in order to obtain the balance needed for the stability of treatment. A sample of 23 patients with atypical swallowing was included in this study, some of them presented thumb sucking and oral breathing. After case history collection, in order to make a correct orthodontic and functional diagnosis, correction of anomalies was carried out since they could compromise the success of the therapy (maxillary contraction, oral breathing, and short lingual fraenum). Then a different therapeutic approach was applied on the basis of the specific dental features. Both from the diagnostic and therapeutic point of view, important results were achieved especially through muscle analysis with dynamometer and surface electromyography. Orthodontic therapy, in the presence of bad habits, is not enough to solve orthodontic issues, it must be combined with a myofunctional treatment. The success of the therapy is granted only when patients and their family comply with the treatment and all factors which can prevent success of the therapy are removed.

The subgingival prevalence of gram-negative facultative rods not usually inhabiting or indigenous to the oral cavity (non-oral GNFR), as well as selected periodontal bacterial pathogens, were evaluated by culture in untreated and treated chronic periodontitis patients. Subgingival biofilm specimens from 102 untreated and 101 recently treated adults with chronic periodontitis in the Netherlands were plated onto MacConkey III and Dentaid selective media with air-5% CO2 incubation for isolation of non-oral GNFR, and onto enriched Oxoid blood agar with anaerobic incubation for recovery of selected periodontal bacterial pathogens. Suspected non-oral GNFR clinical isolates were identified to a species level with the VITEK 2 automated system. A total of 87 (42.9%) out of 203 patients yielded subgingival non-oral GNFR. Patients recently treated with periodontal mechanical debridement therapy demonstrated a greater prevalence of non-oral GNFR (57.4% vs 28.4%, P < 0.0001), and a greater number of different non-oral GNFR species (23 vs 14 different species), than untreated patients. Sphingomonas paucimobilis was the most frequently isolated subgingival non-oral GNFR species. Several GNFR species normally found in animals and human zoonotic infections, and not previously detected in human subgingival biofilms, were recovered from some patients, including Bordetella bronchispetica, Pasteurella canis, Pasteurella pneumotropica and Neisseria zoodegmatis. Porphyromonas gingivalis and Tannerella forsythia were significantly associated with the presence of subgingival non-oral GNFR. A surprisingly high proportion of Dutch chronic periodontitis patients yielded cultivable non-oral GNFR in periodontal pockets, particularly among those recently treated with periodontal mechanical debridement therapy. Since non-oral GNFR species may resist mechanical debridement from periodontal pockets, and are often not susceptible to many antibiotics frequently used in periodontal practice, their

To assess the oral health status of autistic children in Chennai. Oral health status was assessed for 483 children with autism, solicited from special education schools, autistic child centres and therapy centres. Conditions assessed were plaque accumulation, gingival health, dental caries, malocclusion, developmental anomalies, oral injuries and restorations. Chi-square and Fisher's exact tests of significance were used to compare groups. Proportions test was used to compare the significance of the parameters between boys and girls. Autistic children with primary dentition showed significantly higher incidence of dental caries (24%), when compared to other oral conditions. Children with mixed dentition had more gingivitis (50%) and children with permanent dentition had more gingivitis (48.96%) and malocclusion (71.15%). All the oral conditions were seen more in boys than girls. Autistic children have significantly poor oral hygiene and higher incidence of malocclusion and dental caries when compared to other oral conditions.

To assess the toxicity of hypoxoside taken orally by 24 patients with lung cancer. Open study with patients taking 1,200-3,200 mg standardised Hypoxis plant extract (200 mg capsules) per day divided in 3 doses in order to maintain metabolite blood levels near 100 micrograms/ml. Patients with histologically proven squamous, large-cell or adenocarcinoma were hospitalised initially at the radiation oncology ward, Karl Bremer Hospital, Bellville, W. Cape. Thereafter they returned every 2 weeks for full clinical examinations. Routine biochemical and haematological measurements were done. Patients underwent regular full clinical examinations including radiographs and computed tomography scanning according to the discretion of the principal investigator. Nineteen patients on hypoxoside therapy survived for an average of 4 months with progression of their primary tumours and metastases, while 5 survived for more than a year. One of them survived for 5 years and histological examination of the primary lesion showed absence of cancer. No toxic effects, in clinical examinations or biochemical or haematological measurements, were found that could be ascribed to the ingestion of hypoxoside. Only one occasion of possible drug intolerance, with anxiety, nausea, vomiting and diarrhoea, was noted. The absence of toxicity warrants further investigation of hypoxoside as an oral prodrug, especially in patients with slow-growing necrotising tumours that are inoperable and have high concentrations of beta-glucuronidase and sulphatase as well as a high sensitivity for rooperol.

The incidence of inflammatory bowel diseases (IBD) - Crohn’s disease (CD) and ulcerative colitis (UC) - has been increasing on a global scale, and progressively, more gastroenterologists will be included in the diagnosis and treatment of IBD. Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

Adverse reactions to medications are common and may have a variety of clinical presentations in the oral cavity. Targeted therapies and the new biologic agents have revolutionized the treatment of cancers, autoimmune diseases, and inflammatory and rheumatologic diseases but have also been associated with adverse events in the oral cavity. Some examples include osteonecrosis, seen with not only bisphosphonates but also antiangiogenic agents, and the distinctive ulcers caused by mammalian target of rapamycin inhibitors. As newer therapeutic agents are approved, it is likely that more adverse drug events will be encountered. This review describes the most common clinical presentations of oral mucosal reactions to medications, namely, xerostomia, lichenoid reactions, ulcers, bullous disorders, pigmentation, fibrovascular hyperplasia, white lesions, dysesthesia, osteonecrosis, infection, angioedema, and malignancy. Oral health care providers should be familiar with such events, as they will encounter them in their practice. Copyright © 2015 Elsevier Inc. All rights reserved.

Oral cancer has become one of the most aggressive types of cancer, killing 140,000 people worldwide every year. Current treatments for oral cancer include surgery and radiation therapies. These procedures can be very effective; however, they can also drastically decrease the quality of life for survivors. New chemotherapeutic treatments are needed to more effectively combat oral cancer. The transmembrane receptor podoplanin (PDPN) has emerged as a functionally relevant oral cancer biomarker and chemotherapeutic target. PDPN expression promotes tumor cell migration leading to oral cancer invasion and metastasis. Here, we describe the role of PDPN in oral squamous cell carcinoma progression, and how it may be exploited to prevent and treat oral cancer. Copyright © 2018 Elsevier Ltd. All rights reserved.

Patients affected by polycythemia vera (PV), a myeloproliferative neoplasm characterized by an elevated red blood cell mass, are at high risk of vascular and thrombotic complications. Conventional therapeutic options aim at reducing vascular and thrombotic risk; low-dose aspirin and phlebotomy are first-line recommendations, for patients at low risk of thrombotic events, whereas cytoreductive therapy, usually hydroxyurea (HU) or interferon alpha, is recommended for high-risk patients. In the present study, we report the case of a patient with persistent oral ulcerations, possibly related to long-lasting HU treatment, firstly treated with topic and systemic corticosteroids and then more effectively with the addition of low-level laser therapy. Laser photobiomodulation has achieved pain control and has contributed to the healing of oral ulcers without any adverse effect; this has permitted a reduction in the dose of systemic corticosteroids and the suspension of the use of the topic ones, due to the long-term stability of oral health, even after the interruption of low-level laser therapy sessions.

Disodium ethylenediaminetetraacetic acid (EDTA) reduced adverse cardiac outcomes in a factorial trial also testing oral vitamins. This report describes the intent-to-treat comparison of the 4 factorial groups overall and in patients with diabetes. This was a double-blind, placebo-controlled, 2 × 2 factorial multicenter randomized trial of 1,708 post-myocardial infarction (MI) patients ≥50 years of age and with creatinine ≤2.0 mg/dL randomized to receive 40 EDTA chelation or placebo infusions plus 6 caplets daily of a 28-component multivitamin-multimineral mixture or placebo. The primary end point was a composite of total mortality, MI, stroke, coronary revascularization, or hospitalization for angina. Median age was 65 years, 18% were female, 94% were Caucasian, 37% were diabetic, 83% had prior coronary revascularization, and 73% were on statins. Five-year Kaplan-Meier estimates for the primary end point was 31.9% in the chelation + high-dose vitamin group, 33.7% in the chelation + placebo vitamin group, 36.6% in the placebo infusion + active vitamin group, and 40.2% in the placebo infusions + placebo vitamin group. The reduction in primary end point by double active treatment compared with double placebo was significant (hazard ratio 0.74, 95% CI 0.57-0.95, P = .016). In patients with diabetes, the primary end point reduction of double active compared with double placebo was more pronounced (hazard ratio 0.49, 95% CI 0.33-0.75, P < .001). In stable post-MI patients on evidence-based medical therapy, the combination of oral high-dose vitamins and chelation therapy compared with double placebo reduced clinically important cardiovascular events to an extent that was both statistically significant and of potential clinical relevance.

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. 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). 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. Oral manifestations appeared when CD4 count decreased below 500 cells/mm 3 . 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. Oral manifestations are highly predictive markers of severe immune deterioration and disease progression in HIV patients.

Oral drug delivery has attracted substantial attention due to its advantages over other administration routes. Bacillus spores, as oral probiotic agents, are applied widely. In this paper, a novel Bacillus spore-based oral colon targeted carrier loading curcumin was developed for colon cancer treatment. Curcumin was linked covalently with the outer coat of Bacillus spore and folate, respectively (SPORE-CUR-FA). Bacillus spores are capable of delivering drugs to the colon area through gastric barrier, taking the advantage of its tolerance to the harsh conditions and disintegration of the outer coat of spores after germination in the colon. The drug release in vitro and in vivo of SPORE-CUR-FA was investigated. Results showed that SPORE-CUR-FA had the characteristics of colon-targeted drug release. Pharmacokinetic studies confirmed that Bacillus spore-based carriers could efficiently improve the oral bioavailability of curcumin. In vitro and in vivo anti-tumor studies showed that SPORE-CUR-FA had substantial ability for inhibiting colon cancer cells. These findings suggest that this Bacillus spore-based oral drug delivery system has a great potential for the treatment of colon cancer. Copyright © 2017 Elsevier B.V. All rights reserved.

This study compared the efficacy of two oral hygiene regimens in reducing oral malodour and the proportions of bacterial species involved in the production of volatile sulphur compounds. Seventy subjects who participated in a halitosis-induction phase and achieved an organoleptic score of ≥ 3.0 [time point 0 (T0)] randomised into two groups: brushing with regular fluoride toothpaste alone (control group) or brushing with regular fluoride toothpaste followed by rinsing with a 0.075% cetylpyridinium chloride (CPC) mouthwash (CPC group). Subjects followed their assigned oral hygiene regimen for 21 days. Then, they underwent an organoleptic examination and measurement of volatile sulphur compounds (VSCs) using a portable gas chromatograph, 12 hours after their last oral hygiene procedure (T1) and 4 hours after an on-site oral hygiene (T2). Microbiological samples (supragingival biofilm, tongue coating and saliva) were analysed using checkerboard DNA-DNA hybridisation. Both therapies statistically significantly improved the organoleptic scores (P < 0.05), but the VSC levels and/or concentrations were reduced only in the CPC group (P < 0.05). In subjects rinsing with CPC, oral malodour scores were reduced by 49% at the 4-hour assessment (T2) compared with those not rinsing (P < 0.05). Red-complex pathogens were reduced more effectively in the CPC group than in the control group. Brushing followed by rinsing with a 0.075% CPC mouthwash provided statistically significantly greater reductions in oral malodour, measured organoleptically and instrumentally, and in the proportions of red-complex species when compared with brushing alone. © 2015 FDI World Dental Federation.

In intensive care units (ICUs), nosocomial infections are prevalent conditions and they have been related to high mortality indexes. Some studies have suggested that inefficient oral hygiene and ventilator-associated pneumonia (VAP) are related. Nowadays, in the Brazilian public health system there is no well-defined protocol for oral hygiene in an ICU. Due to the drawbacks of the use of antibiotics, photodynamic therapy (PDT) has emerged as an interesting technique in order to reduce antimicrobial-resistant pathogens. Methylene blue (MB) is the most common chemical agent for PDT in Brazil. However, new formulations for improved effectiveness are still lacking. The objective of this study is to evaluate the use of an MB mouthwash as an effective oral-hygiene procedure in an ICU and to show that oral hygiene using PDT with MB mouthwash may reduce VAP frequency to rates similar to, or higher than, chlorhexidine. Phase 1 will evaluate the most effective cleaning procedure, while phase 2 will correlate oral hygiene to VAP incidence. At the start of phase 1, the ICU patients will be randomly allocated into three different groups (10 patients/group): the efficacy of chlorhexidine, classical MB-PDT, and mouthwash MB-PDT will all be measured for the quantification of viable bacteria, both pre- and post-treatment, by a Reverse Transcription Polymerase Chain Reaction (RT-PCR). In phase 2, the most effective procedure found in phase 1 and a mechanical cleaning with filtered water will be carried out daily, once a day, over 5 days, with a total of 52 ICU patients randomly allocated into the two groups. The clinical records will be evaluated in order to find any pneumonic diagnoses. Since a variety of bacterial species are related to VAP, a universal primer for bacteria will be used in order to quantify the total bacteria count in the participants' samples. In order to quantify only the living bacteria before DNA extraction, the samples will be treated with propidium monoazide

The purpose of this study was to investigate the therapeutic efficacy of oral moxifloxacin for aerobic vaginitis (AV). We also identified factors that are associated with therapeutic efficacy. This prospective study enrolled general gynecological outpatients at Tianjin Medical University General Hospital between September 2012 and May 2014. Women diagnosed with AV (n = 102) were recruited. All enrolled women were treated with oral moxifloxacin, 400 mg once daily for 6 days (one course). Therapeutic efficacy was evaluated based on microscopic criteria, and cure rates were calculated. Women who were microscopically improved (but not cured) received a second course of therapy. Women classified with microscopic failure were treated using other strategies. Univariate and multivariate logistic regression analysis was used to identify factors that may be associated with a cure after one course of therapy. After one course of therapy, 65.7 % (67/102) of women were cured, 29.4 % (30/102) of women were improved (but not cured), 4.9 % (5/102) of women failed to respond to the therapy. After two courses of therapy, 85.3 % (87/102) of women were cured, 9.8 % (10/102) of women were improved, 4.9 % (5/102) of women failed to respond to the therapy, and clinical improvement was achieved in additional women. In the multivariate logistic regression analysis, women with a baseline vaginal pH value of <5.0 had a 3.5-times higher chance of being cured, compared with those with a baseline vaginal pH value of ≥5.0 (OR, 3.503; 95 % CI, 1.278-9.601). Moxifloxacin is an effective therapeutic option for patients with AV. Most women with AV were cured with one course of moxifloxacin. For those with a higher vaginal pH value of ≥5.0 before treatment, two courses of therapy should be considered.

Oral mucositis is a common side effect of systemic chemotherapy and radiotherapy of head and neck in patients with cancer. Severe oral mucositis is painful and affects oral functions, including intake of food and medications and speech. Prevention of oral mucositis affects the life quality of patients. Recent studies have been focused on natural products to improve or reduce this complication. Many clinical trials have been performed to assess natural products for treatment of mucositis and their results are promising. The authors reviewed the evidence for natural products in the prevention and treatment of oral mucositis induced by radiation therapy and chemotherapy. PMID:26306626

Little is known about the immunosuppressive effect of glucocorticoids on TSH receptor antibodies. We observed the long-term prognosis and serum TSH binding inhibitor immunoglobulin (TBII) levels in patients with Graves' ophthalmopathy who had received intravenous methylprednisolone pulse therapy (pulse therapy) followed by oral prednisolone administration in order to ascertain how long the immunosuppressive effect of glucocorticoids continued. This is the first report on the effect of pulse therapy on Graves' disease outcome. We observed 67 patients who were treated by antithyroid drugs (ATD) alone for 2 years after pulse therapy. TBII was evaluated before and 3, 6, 12, 18, and 24 months after pulse therapy. The mean TBII decreased significantly 3 months after pulse therapy (p<0.001), and was maintained until 24 months. There were 24 patients whose TBII was positive (>15%) at 24 months, in whom the mean TBII decreased significantly 3 to 6 months after pulse therapy (p<0.001), but increased again at 12 to 24 months (p<0.05). Thus, the immunosuppressive effect of glucocorticoids may be lost at 12 months after pulse therapy in these patients. The remission rate in the pulse therapy group was 40.98%, and that of the control patient group was 48.57%. There was no significant difference between the two. These results suggest that the immunosuppressive effect of pulse therapy was temporary, and that pulse therapy did not increase remission rate of Graves' disease.

Oral ivermectin is an alternative therapy for human scabies infection due to its ease of administration and good safety profile. However, there is no definitive consensus on the optimal dosing regimen. To describe the treatment of human scabies with different dosages of oral ivermectin and the possible adverse events. 23 patients with human scabies were treated with oral ivermectin: 10 patients received a single oral dose of 200μg/kg and 13 a dose of 400μg/kg. A second, or even a third dose, was administered in cases of treatment failure. A complete clinical response was achieved by all of the patients. The first ten patients required at least two (80%) or three (20%) doses of ivermectin for complete resolution of the infection. The remaining cases resolved with a single 400μg/kg oral dose. Within the first 72h after the administration of oral ivermectin, new cutaneous lesions were observed in eleven patients (47.8%). Cutaneous biopsies showed signs of subacute eczema. The eruption was treated with topical corticosteroids and emollient therapy. There was no other new drug administration or a history of irritants. There was no history of atopic diathesis except for one patient. Oral ivermectin is an effective therapy for the treatment of human scabies. A single 400μg/kg oral dose demonstrated high efficacy and good tolerance. However, the appearance of eczematous cutaneous lesions induced by oral ivermectin has not previously been reported in the literature. Dermatologists should be aware of this possible adverse event.

Once initiated for pulmonary arterial hypertension (PAH), epoprostenol treatment usually needs to be delivered for an indefinite duration. It is possible that some participants could be transitioned from epoprostenol to oral therapies. We retrospectively evaluated eight PAH participants transitioned from epoprostenol to PAH oral drugs. The criteria for epoprostenol withdrawal were: (1) persistent improvement of clinic and hemodynamic status; (2) stable dose of epoprostenol for the last three months; and (3) the participant's preference for oral therapy after evaluation of risk-benefit. We evaluated the clinical, functional, and hemodynamic status at baseline, at withdrawal, and after the transition to oral PAH therapy. The transition was completed in all eight participants. Four participants had a complete successful transition (CT) with a stable clinical and hemodynamic course and four participants had a partial successful transition (PT) remaining stable clinically, with a mild hemodynamic worsening, but without need to re-initiate epoprostenol therapy. The four CT participants were treated with epoprostenol for a shorter period of time (CT group: 35 ± 30 versus PT group: 79 ± 49 months, P = 0.08). Mean epoprostenol dosage was lower in the CT group (CT group: 15 ± 1.5 ng/kg/min versus PT group: 24 ± 11 ng/kg/min, P = 0.09). Safe withdrawal of epoprostenol treatment and transition to oral PAH therapy was possible in a small and highly selected group of participants. The majority of these participants had a porto-pulmonary PAH or PAH associated to HIV infection.

Reducing deaths from diarrhoea through oral rehydration therapy.

In 1980, diarrhoea was the leading cause of child mortality, accounting for 4.6 million deaths annually. Efforts to control diarrhoea over the past decade have been based on multiple, potentially powerful interventions implemented more or less simultaneously. Oral rehydration therapy (ORT) was introduced in 1979 and rapidly became the cornerstone of programmes for the control of diarrhoeal diseases. We report on the strategy for controlling diarrhoea through case management, with special reference to ORT, and on the relationship between its implementation and reduced mortality. Population-based data on the coverage and quality of facility-based use of ORT are scarce, despite its potential importance in reducing mortality, especially for severe cases. ORT use rates during the 1980s are available for only a few countries. An improvement in the availability of data occurred in the mid-1990s. The study of time trends is hampered by the use of several different definitions of ORT. Nevertheless, the data show positive trends in diarrhoea management in most parts of the world. ORT is now given to the majority of children with diarrhoea. The annual number of deaths attributable to diarrhoea among children aged under 5 years fell from the estimated 4.6 million in 1980 to about 1.5 million today. Case studies in Brazil, Egypt, Mexico, and the Philippines confirm increases in the use of ORT which are concomitant with marked falls in mortality. In some countries, possible alternative explanations for the observed decline in mortality have been fairly confidently ruled out. Experience with ORT can provide useful guidance for child survival programmes. With adequate political will and financial support, cost-effective interventions other than that of immunization can be successfully delivered by national programmes. Furthermore, there are important lessons for evaluators. The population-based data needed to establish trends in health service delivery, outcomes and impact are not

Candida glabrata: an emerging oral opportunistic pathogen.

PubMed

Li, L; Redding, S; Dongari-Bagtzoglou, A

2007-03-01

Following the widespread use of immunosuppressive therapy and broad-spectrum antimycotic prophylaxis, C. glabrata has emerged as an important opportunistic pathogen in the oral mucosa. In the past, studies on the virulence factors and host-pathogen interactions of this organism were scarce, but continued to rise in recent years. Denture-wearing, immunosuppression, antibiotic therapy, and aging are risk factors for oral colonization or infection with C. glabrata. Compared with C. albicans, C. glabrata exhibits lower oral keratinocyte-adherence capacity, but higher denture-surface-adherence ability. The role of extracellular hydrolase production in the virulence of this organism does not appear to be as important as it is in C. albicans pathogenesis. Although traditionally thought of as a non-transforming yeast organism, both phenotypic switching and pseudohyphal formation have recently been identified in C. glabrata, but their role in pathogenesis is not known. With the exception of granulocyte monocyte colony-stimulating factor, C. glabrata triggers a lower proinflammatory cytokine response in oral epithelial cells than does C. albicans, in a strain-dependent manner. C. glabrata is less susceptible to killing by human beta-defensins than is C. albicans and exhibits various degrees of resistance to the antifungal activity of salivary histatins and mucins. In addition, C. glabrata possesses both innate and acquired resistance against antifungal drugs, due to its ability to modify ergosterol biosynthesis, mitochondrial function, or antifungal efflux. This resistance allows for its relative overgrowth over other susceptible species and may contribute to the recent emergence of C. glabrata infections in chronically immunocompromised populations. Further investigations on the virulence and host-pathogen interactions of C. glabrata are needed to better define the pathogenesis of oral C. glabrata infection in susceptible hosts.

Oral and intestinal mucositis - causes and possible treatments.

PubMed

Duncan, M; Grant, G

2003-11-01

Chemotherapy and radiotherapy, whilst highly effective in the treatment of neoplasia, can also cause damage to healthy tissue. In particular, the alimentary tract may be badly affected. Severe inflammation, lesioning and ulceration can occur. Patients may experience intense pain, nausea and gastro-enteritis. They are also highly susceptible to infection. The disorder (mucositis) is a dose-limiting toxicity of therapy and affects around 500 000 patients world-wide annually. Oral and intestinal mucositis is multi-factorial in nature. The disruption or loss of rapidly dividing epithelial progenitor cells is a trigger for the onset of the disorder. However, the actual dysfunction that manifests and its severity and duration are greatly influenced by changes in other cell populations, immune responses and the effects of oral/gut flora. This complexity has hampered the development of effective palliative or preventative measures. Recent studies have concentrated on the use of bioactive/growth factors, hormones or interleukins to modify epithelial metabolism and reduce the susceptibility of the tract to mucositis. Some of these treatments appear to have considerable potential and are at present under clinical evaluation. This overview deals with the cellular changes and host responses that may lead to the development of mucositis of the oral cavity and gastrointestinal tract, and the potential of existing and novel palliative measures to limit or prevent the disorder. Presently available treatments do not prevent mucositis, but can limit its severity if used in combination. Poor oral health and existing epithelial damage predispose patients to mucositis. The elimination of dental problems or the minimization of existing damage to the alimentary tract, prior to the commencement of therapy, lowers their susceptibility. Measures that reduce the flora of the tract, before therapy, can also be helpful. Increased production of free radicals and the induction of inflammation are

Periodontal Therapy Effects on Nitrite Related to Oral Bacteria: A 6-Month Randomized Clinical Trial.

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 <0.05). Nitrite concentrations did not tend to change over time. Regarding CHX use, there was a negative correlation between nitrite and total bacterial load at 6 months (FMS + CHX) and one positive correlation between P. gingivalis and nitrite at baseline (QS + CHX). Independently of rinse type, in the FMS group, nitrite correlated negatively with several microbial parameters and also with a higher percentage of deep 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.

Effect of topical honey on limitation of radiation-induced oral mucositis: an intervention study.

PubMed

Khanal, B; Baliga, M; Uppal, N

2010-12-01

Radiation therapy for oral carcinoma is therapeutically useful in dose of at least 6000 cGy but causes mucositis that severely interferes with oral function. The literature indicates that honey appears to promote wound healing, so the authors investigated whether its anti-inflammatory properties might limit the severity of radiation-induced oral mucositis. A single-blinded, randomized, controlled clinical trial was carried out to compare the mucositis-limiting qualities of honey with lignocaine. A visual assessment scale permitted scoring of degrees of mucositis and statistical evaluation of the results was performed using the χ(2) test. Only 1 of 20 patients in the honey group developed intolerable oral mucositis compared with the lignocaine group, indicating that honey is strongly protective (RR=0.067) against the development of mucositis. The proportion of patients with intolerable oral mucositis was lower in the honey group and this was statistically significant (p=0.000). Honey applied topically to the oral mucosa of patients undergoing radiation therapy appears to provide a distinct benefit by limiting the severity of mucositis. Honey is readily available, affordable and well accepted by patients making it useful for improving the quality of life in irradiated patients.

Melasma is a common acquired hyperpigmentary disorder, particularly among Asians and Hispanics, but its exact pathomechanism is poorly understood. Tranexamic acid has been found to lighten melasma by interfering with the interaction of melanocytes and keratinocytes by inhibiting the plasminogen/plasmin system. The aim was to evaluate the therapeutic effects of oral tranexamic acid in the treatment of melasma refractory to topical skin-lightening agents. This retrospective study analyses patients with melasma recruited from a tertiary dermatological centre in Singapore between 1 August 2009 and 31 March 2011. The patients chosen had refractory melasma treated with oral tranexamic acid 250 mg twice daily in addition to pre-existing combination topical therapy. Objective assessment using the physician's global assessment and melasma area and severity index (MASI) scores were performed based on a post-hoc analysis of photographic records by three independent physicians. A paired t-test was used to evaluate the changes in the MASI scores pre-therapy and post-treatment. Statistical significance was defined as P < 0.05. Altogether 25 patients were treated with tranexamic acid for a mean period of 3.7 ± 0.33 months, in addition to combination topical therapy. Their mean age was 47.2 ± 1.61 years. The mean MASI scores after tranexamic acid treatment (2.7 ± 1.6) were significantly lower (P < 0.01) than those prior to treatment (8.8 ± 4.2). The mean improvement in scores was 69%. The follow-up period was up to 6 months. Low-dose oral tranexamic acid can serve as a safe and useful adjunct in the treatment of refractory melasma. © 2016 The Australasian College of Dermatologists.

Oral innate immunity in HIV infection in HAART era

2015-01-01

Oral innate immunity, an important component in host defense and immune surveillance in the oral cavity, plays a crucial role in the regulation of oral health. As part of the innate immune system, epithelial cells lining oral mucosal surfaces provide not only a physical barrier but also produce different antimicrobial peptides, including human β-defensins (hBDs), secretory leukocyte protease inhibitor (SLPI), and various cytokines. These innate immune mediators help in maintaining oral homeostasis. When they are impaired either by local or systemic causes, various oral infections and malignancies may be developed. Human immunodeficiency virus (HIV) infection and other co-infections appear to have both direct and indirect effects on systemic and local innate immunity leading to the development of oral opportunistic infections and malignancies. Highly active antiretroviral therapy (HAART), the standard treatment of HIV infection contributed to a global reduction of HIV-associated oral lesions. However, prolonged treatment by HAART may lead to adverse effects on the oral innate immunity resulting in the relapse of oral lesions. This review article focused on the roles of oral innate immunity in HIV infection in HAART era. The following five key questions were addressed: 1) What are the roles of oral innate immunity in health and disease?, 2) What are the effects of HIV infection on oral innate immunity?, 3) What are the roles of oral innate immunity against other co-infections?, 4) What are the effects of HAART on oral innate immunity?, and 5) Is oral innate immunity enhanced by HAART?

The numerous microbial species in oral biofilms: how could antibacterial therapy be effective?

PubMed

ten Cate, J M; Zaura, E

2012-09-01

Hundreds of bacterial species inhabit the oral cavity. Many of these have never been cultivated and can be assessed only with DNA-based techniques. This new understanding has changed the paradigm of the etiology of oral disease from that associated with 'traditional pathogens' as being primarily responsible for all diseases. Increasingly, associations between oral bacteria and systemic diseases are being reported. The emergence of antibiotic resistance is alarming and calls for in-depth studies of biofilms, bacterial physiology, and a body-wide approach to infectious diseases. We propose that the borderline between commensal bacteria and pathogens is no longer discrete. In a field of science where so many of the established paradigms are being undermined, a thorough analysis of threats and opportunities is required. This article addresses some of the questions that can be raised and serves to identify research opportunities and needs to leverage the prevention of oral diseases through novel antimicrobial strategies.

WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Erectile dysfunction after nerve-sparing radical retropubic prostatectomy constitutes a challenge to the urologist. The mainstay of medical treatment after radical prostatectomy to restore spontaneous erectile function remains phosphodiesterase (PDE5) inhibitors, despite the fact that data from animal studies suggesting that PDE5 inhibitors can prevent smooth muscle apoptosis and fibrosis have not yet been extrapolated to humans because of a lack of standardized protocols. If the above treatment fails, second-line therapies such as intraurethral prostaglandins, penile injection therapy and vacuum devices are offered. When less invasive therapies are ineffective, interventions that preserve sexual function such as penile prosthesis implantation become the treatment of choice. Our study reveals the alternative of penile prosthesis implantation as first-line treatment in erectile dysfunction after nerve-sparing radical prostatectomy. It also highlights its superiority to the oral PDE5 inhibitor treatment, regarding the erection, frequency, firmness, maintenance and penetration ability. This suggests that a concept of an early penile intervention in the future would be promising for those patients who wish to remain sexually active without depending on oral formulations with doubtful and delayed results. To evaluate the outcome of penile prosthesis surgery in comparison to oral phosphodiesterase type 5 (PDE5) inhibitor administration, in men with erectile dysfunction after nerve-sparing radical prostatectomy, as early penile intervention therapy. A total of 174 patients treated by nerve-sparing retropubic radical prostatectomy (RRP) for clinically localized prostate cancer, between January 2006 and September 2009 enrolled in the study, 153 patients fulfilled the inclusion criteria, and 69 (45%) patients presented with post-RRP erectile dysfunction 6 months after primary surgery.

Pseudomonas aeruginosa is the most common bacterial pathogen causing lung infections in people with cystic fibrosis and appropriate antibiotic therapy is vital. Antibiotics for pulmonary exacerbations are usually given intravenously, and for long-term treatment, via a nebuliser. Oral anti-pseudomonal antibiotics with the same efficacy and safety as intravenous or nebulised antibiotics would benefit people with cystic fibrosis due to ease of treatment and avoidance of hospitalisation. This is an update of a previous review. To determine the benefit or harm of oral anti-pseudomonal antibiotic therapy for people with cystic fibrosis, colonised with Pseudomonas aeruginosa, in the:1. treatment of a pulmonary exacerbation; and2. long-term treatment of chronic infection. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.We contacted pharmaceutical companies and checked reference lists of identified trials.Date of last search: 08 July 2016. Randomised or quasi-randomised controlled trials comparing any dose of oral anti-pseudomonal antibiotics, to other combinations of inhaled, oral or intravenous antibiotics, or to placebo or usual treatment for pulmonary exacerbations and long-term treatment. Two authors independently selected the trials, extracted data and assessed quality. We contacted trial authors to obtain missing information. We included three trials examining pulmonary exacerbations (171 participants) and two trials examining long-term therapy (85 participants). We regarded the most important outcomes as quality of life and lung function. The analysis did not identify any statistically significant difference between oral anti-pseudomonal antibiotics and other treatments for these outcome measures for either pulmonary exacerbations or long-term treatment.

Direct oral anticoagulants (DOAC) are alternatives to the use of vitamin K antagonists (VKA) as oral anticoagulant therapies to prevent stroke in patients with atrial fibrillation. We assembled a representative secondary prevention cohort from four tertiary care stroke centers to identify factors that independently influence therapeutic decision making 1) not to anticoagulate with either VKA or DOAC and 2) to use DOAC if the patient appears suitable for oral anticoagulant therapy. We identified all patients discharged with the diagnoses 'ischemic stroke' (ICD-10 code I63) or 'transient ischemic attack' (G45) in combination with 'atrial fibrillation' (I48) during 1 year. We performed binary logistic regression analyses to identify factors independently influencing the aforementioned decisions. Our cohort comprised 758 patients. At discharge from the stroke service, 374 patients (49·3%) received oral anticoagulant therapy. Older age, severe stroke, poor recovery in the acute phase, and higher serum creatinine were independent factors to withhold oral anticoagulant therapy, whereas prior oral anticoagulant therapy favored the decision to anticoagulate. Among patients who were anticoagulated, prescription was balanced for VKA (50·3%) and DOAC (49·7%). Renal function and prior oral anticoagulant therapies were the most important factors in this decision. Shortly after their marketing, DOAC are used as frequently as VKA for secondary stroke prevention in patients with atrial fibrillation. The decision between VKA and DOAC is mainly determined by the patient's renal function and the absence or presence of prior oral anticoagulant therapy. © 2014 World Stroke Organization.

This paper discusses the importance of oral lesions as indicators of infection with human immunodeficiency virus (HIV) and as predictors of progression of HIV disease to acquired immunodeficiency syndrome (AIDS). Oral manifestations are among the earliest and most important indicators of infection with HIV. Seven cardinal lesions, oral candidiasis, hairy leukoplakia, Kaposi sarcoma, linear gingival erythema, necrotizing ulcerative gingivitis, necrotizing ulcerative periodontitis and non-Hodgkin lymphoma, which are strongly associated with HIV infection, have been identified and internationally calibrated, and are seen in both developed and developing countries. They may provide a strong indication of HIV infection and be present in the majority of HIV-infected people. Antiretroviral therapy may affect the prevalence of HIV-related lesions. The presence of oral lesions can have a significant impact on health-related quality of life. Oral health is strongly associated with physical and mental health and there are significant increases in oral health needs in people with HIV infection, especially in children, and in adults particularly in relation to periodontal diseases. International collaboration is needed to ensure that oral aspects of HIV disease are taken into account in medical programmes and to integrate oral health care with the general care of the patient. It is important that all health care workers receive education and training on the relevance of oral health needs and the use of oral lesions as surrogate markers in HIV infection. PMID:16211162

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

Radiation-Induced Oral Mucositis

Radiation-induced oral mucositis (RIOM) is a major dose-limiting toxicity in head and neck cancer patients. It is a normal tissue injury caused by radiation/radiotherapy (RT), which has marked adverse effects on patient quality of life and cancer therapy continuity. It is a challenge for radiation oncologists since it leads to cancer therapy interruption, poor local tumor control, and changes in dose fractionation. RIOM occurs in 100% of altered fractionation radiotherapy head and neck cancer patients. In the United Sates, its economic cost was estimated to reach 17,000.00 USD per patient with head and neck cancers. This review will discuss RIOM definition, epidemiology, impact and side effects, pathogenesis, scoring scales, diagnosis, differential diagnosis, prevention, and treatment. PMID:28589080

Boron neutron capture therapy (BNCT) is based on selective accumulation of ¹⁰B carriers in tumor followed by neutron irradiation. We previously proved the therapeutic success of BNCT mediated by the boron compounds boronophenylalanine and sodium decahydrodecaborate (GB-10) in the hamster cheek pouch oral cancer model. Based on the clinical relevance of the boron carrier sodium borocaptate (BSH) and the knowledge that the most effective way to optimize BNCT is to improve tumor boron targeting, the specific aim of this study was to perform biodistribution studies of BSH in the hamster cheek pouch oral cancer model and evaluate the feasibility of BNCT mediated by BSH at nuclear reactor RA-3. The general aim of these studies is to contribute to the knowledge of BNCT radiobiology and optimize BNCT for head and neck cancer. Sodium borocaptate (50 mg ¹⁰B/kg) was administered to tumor-bearing hamsters. Groups of 3-5 animals were killed humanely at nine time-points, 3-12 h post-administration. Samples of blood, tumor, precancerous pouch tissue, normal pouch tissue and other clinically relevant normal tissues were processed for boron measurement by optic emission spectroscopy. Tumor boron concentration peaked to therapeutically useful boron concentration values of 24-35 ppm. The boron concentration ratio tumor/normal pouch tissue ranged from 1.1 to 1.8. Pharmacokinetic curves showed that the optimum interval between BSH administration and neutron irradiation was 7-11 h. It is concluded that BNCT mediated by BSH at nuclear reactor RA-3 would be feasible.

In the past 18 months, the U.S. Food and Drug Administration approved macitentan, riociguat, and treprostinil as oral agents for the treatment of pulmonary arterial hypertension (PAH); riociguat also became the first agent approved for the treatment of chronic thromboembolic pulmonary hypertension (CTEPH). These new agents are welcome additional therapeutic options for PAH and CTEPH. However, their use can be complicated by potential drug interactions, adverse effects, dosing complexity, and cost. Macitentan, the newest endothelin receptor antagonist, showed significant benefits in a long-term event-driven trial of morbidity and mortality. Dosed once daily and with minimal liver toxicity, it has potential drug interactions with potent CYP 3A4 inhibitors and inducers, and can decrease hemoglobin levels. Riociguat is approved for PAH and clinically inoperable CTEPH to improve exercise capacity and functional status. Riociguat requires dose titration beginning with 1 mg up to 2.5 mg three times a day, as tolerated, and should be used with caution in patients with underlying risk factors for systemic hypotension. Oral treprostinil, approved to improve exercise capacity in PAH, is associated with gastrointestinal side effects and headaches that are often dose limiting. Doses can begin with 0.125 mg or 0.25 mg twice a day with gradual increases on up to a weekly basis, as tolerated. Thrice daily dosing and administration with a meal can improve tolerance. These newer agents represent advances, but their specific roles in relation to pre-existing therapies are undergoing further evaluation. Therefore, close collaboration with clinicians at centers with therapeutic expertise is highly recommended to optimize patient outcomes.

Gene therapy holds a promising future for bridging the gap between the disciplines of medicine and clinical dentistry. The dynamic treatment approaches of gene therapy have been advancing by leaps and bounds. They are transforming the conventional approaches into more precise and preventive ones that may limit the need of using drugs and surgery. The oral cavity is one of the most accessible areas for the clinical applications of gene therapy for various oral tissues. The idea of genetic engineering has become more exciting due to its advantages over other treatment modalities. For instance, the body is neither subjected to an invasive surgery nor deep wounds, nor is it susceptible to systemic effects of drugs. The aim of this article is to review the gene therapy applications in the field of dentistry. In addition, therapeutic benefits in terms of treatment of diseases, minimal invasion and maximum outcomes have been discussed. PMID:27834914

Use of Probiotics and Oral Health.

Allaker, Robert P; Stephen, Abish S

2017-01-01

The purpose of this study is to critically assess recent studies concerning the use of probiotics to control periodontal diseases, dental caries and halitosis (oral malodour). Clinical studies have shown that probiotics when allied to conventional periodontal treatment can ameliorate microbial dysbiosis and produce significant improvement in clinical indicators of disease. However, this effect is often not maintained by the host after the end of probiotic use. Current probiotics also show limited effects in treating caries and halitosis. Novel approaches based up on replacement therapy and using highly abundant health-associated oral species, including nitrate-reducing bacteria, have been proposed to improve persistence of probiotic strains and maintain oral health benefits. Probiotics have potential in the management of multifactorial diseases such as the periodontal diseases and caries, by more effectively addressing the host-microbial interface to restore homeostasis that may not be achieved with conventional treatments.

The development of orally active pulmonary vasodilators has been a major breakthrough in the treatment of pulmonary arterial hypertension (PAH). Orally active medications greatly enhanced patient access to PAH treatment and increased an interest in the diagnosis and treatment of this disease that still continues. Four different orally active drugs are currently available for the treatment of PAH and several more are undergoing evaluation. This article discusses the mechanisms by which endothelin receptor antagonists and phosphodiesterase-5 inhibitors mitigate pulmonary hypertensive responses, and reviews the most recent data concerning their efficacy and limitations in the treatment of PAH.

2014-05-01

Optimal coverage of insulin needs is the paramount aim of insulin replacement therapy in patients with diabetes mellitus. To apply insulin without breaking the skin barrier by a needle and/or to allow a more physiological provision of insulin are the main reasons triggering the continuous search for alternative routes of insulin administration. Despite numerous attempts over the past 9 decades to develop an insulin pill, no insulin for oral dosing is commercially available. By way of a structured approach, we aim to provide a systematic update on the most recent developments toward an orally available insulin formulation with a clear focus on data from clinical-experimental and clinical studies. Thirteen companies that claim to be working on oral insulin formulations were identified. However, only 6 of these companies published new clinical trial results within the past 5 years. Interestingly, these clinical data reports make up a mere 4% of the considerably high total number of publications on the development of oral insulin formulations within this time period. While this picture clearly reflects the rising research interest in orally bioavailable insulin formulations, it also highlights the fact that the lion's share of research efforts is still allocated to the preclinical stages. © 2014 Diabetes Technology Society.

To compare efficacy, compliance rates, and side effects of a new strapless oral interface, the Oracle, with available nasal masks over 8 weeks of use for the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS). A total of 38 patients with OSAHS (respiratory disturbance index (RDI) >/=15/h) were enrolled after the diagnostic polysomnogram for subsequent continuous positive airway pressure (CPAP) therapy. After randomization, therapeutic pressures during a titration study were determined for 21 patients in the oral group and 17 patients in the nasal group. Comparisons for nasal and oral interfaces were made for baseline patient characteristics, average hours of CPAP use, side effects from therapy, and among questionnaires evaluating patients' subjective responses to therapy at months 1 and 2. No significant difference was observed in the average hours of CPAP use between the oral (4.5+/-2.1; 5.5+/-2.6) and nasal groups (4.0+/-2.6; 4.8+/-2.5) for either month 1 or 2 (P>0.05). The dropout rates were similar for both groups after 8 weeks of therapy. However, patients in the nasal group had higher occurrences of side effects such as nasal congestion, dryness, and air leaks, whereas patients in the oral group experienced more oral dryness and gum pain. Oral delivery of CPAP with the Oracle is an effective and suitable alternative for patients with OSAHS.

The aim of our study was to evaluate antimicrobial prescription behaviour amongst dentists performing oral implant surgery in India. Dentists performing oral implant surgery from different parts of India were personally approached during various national events such as conferences and academic meetings and information regarding their prescription habits for antimicrobial agents in routine oral implant surgery was collected using a structured questionnaire. Out of a total sample of 332 dentists, 85.5 % prescribed 17 different groups or combinations of antibiotics routinely for oral implant surgery in the normal healthy patient. Majority preferred the peri-operative protocol of drug therapy (72.2 %) with variable and prolonged duration of therapy after surgery, ranging from 3 to 10 days. An antimicrobial mouthwash was routinely prescribed by all the doctors (14.5 %) not in favour of prescribing antimicrobials in a normal healthy patient. Our findings suggest that there is a trend of antimicrobial agent misuse by dentists performing oral implant surgery in India, both in terms of drugs used and the protocols prescribed. The majority of these dentists prescribed a variety of antimicrobial agents for prolonged durations routinely even in the normal, healthy patients.

Purpose Multi-modality therapy has resulted in improved survival for childhood malignancies. The Children’s Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancers provide practitioners with exposure- and risk-based recommendations for the surveillance and management of asymptomatic survivors who are at least 2 years from completion of therapy. This review outlines the pathophysiology and risks for oral and dental late effects in pediatric cancer survivors and the rationale for oral and dental screening recommended by the Children’s Oncology Group. Methods An English literature search for oral and dental complications of childhood cancer treatment was undertaken via MEDLINE and encompassed January 1975 to January 2013. Proposed guideline content based on the literature review was approved by a multi-disciplinary panel of survivorship experts and scored according to a modified version of the National Comprehensive Cancer Network “Categories of Consensus” system. Results The Children’s Oncology Group oral-dental pan el selected 85 relevant citations. Childhood cancer therapy may impact tooth development, salivary function, craniofacial development, and temporomandibular joint function placing some childhood cancer survivors at an increased risk for poor oral and dental health. Addition ally, head and neck radiation and hematopoietic stem cell transplantation increase the risk of subsequent ma lignant neoplasms in the oral cavity. Survivors require routine dental care to evaluate for potential side effects and initiate early treatment. Conclusions Certain childhood cancer survivors are at an increased risk for poor oral and dental health. Early identification of oral and dental morbidity and early interventions can optimize health and quality of life. PMID:24781353

The purpose of this study was to ascertain the effectiveness of a culturally appropriate promotora training program related to oral rehydration therapy and diarrheal management. Factors that influenced the development, implementation, and evaluation of the program provided to low-literacy women in Guatemala are explored. Promotora training was conducted with 15 Mayan women from a rural community in the highlands of Guatemala. Women were selected by leaders of the community to participate in the program. Quantitative data were collected and analyzed to determine descriptive statistics and reliability coefficients for the pretests and posttests. A nonparametric Wilcoxon test for paired-samples was conducted. The qualitative data from the program evaluations were analyzed for themes. Mean scores increased from 41.73 (SD = 9.65) to 70.33 (SD = 21.29) on the pretest and posttest. The Cronbach's alpha was 0.54 on the pretest with 0.65 on the posttest. The Wilcoxon test demonstrated a significant difference between the pretest and posttest scores (Z = 3.040, p < .05). Extremely low-literacy levels played a major role in the ability of the women to successfully complete the requirements of the training program. The curriculum demonstrated effectiveness, but will benefit from replication with a larger sample. © 2014 Wiley Periodicals, Inc.

Herbs in Oral Mucositis

Baharvand, Maryam; Jafari, Soudeh

2017-01-01

Oral mucositis is an inflammatory mucosal destruction as a result of chemotherapy and/or radiation therapy, which in severe cases can impair patients’ quality of life. Moreover, mucosal infection and/or systemic involvement due to compromised immunity leads to delay or discontinuation of the treatment. Many strategies and agents have been suggested for the management of this condition. Because of their lower side effects compared to chemical drugs, general interest in evaluating therapeutic effects of herbs has been increased intensively. Herbal plants apply their effect through different mechanisms of action: antioxidant, analgesic, anti-inflammatory, antifungal, antiseptic, and anticarcinogenic activity. Recently, various natural agents in plants have been noticed in mucositis, which may improve the symptoms through different interventions. The purpose of this review is to focus on the preventive or therapeutic use of herbal medicine to alleviate oral mucositis. PMID:28511530

(1) Patients treated with high-dose chemotherapy combined with total body irradiation (myeloablative therapy) often develop oral mucositis. Prevention is based mainly on sucking ice during chemotherapy. (2) Palifermin is a growth factor marketed for the prevention of severe oral mucositis in adults with malignant haemopathies who are receiving myeloablative therapy followed by peripheral stem cell autografting. (3) Palifermin has not been compared with sucking ice, despite the efficacy of this simple treatment. (4) In a randomised placebo-controlled double-blind trial involving 212 adult patients treated with high-dose chemotherapy and total body irradiation, palifermin reduced the incidence of severe oral mucositis (63% versus 98%) and its duration (about 3 days versus 9 days). The myeloablative regimen used in this trial is not that commonly used in Europe. The efficacy of palifermin during less aggressive regimens, which cause less severe oral mucositis, is not known. (5) The main adverse events noted in clinical trials were erythema and cutaneous oedema. It is not known whether palifermin increases the long-term risk of cancer. (6) Treatment with palifermin is expensive, 4800.00 euros in France); the optimal dosing schedule is not known and the unit dose chosen by the manufacturer is wastefully large. (7) In practice, it remains to be demonstrated that palifermin is more effective than simply sucking ice.

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

Postoperative hypocalcemia is the most common complication after total thyroidectomy. 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 < 0.05). No statistical difference can be observed regarding the timing of serum biomarkers. Serum PTH levels at postoperative 12 and 24 h can predict early post-thyroidectomy 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.

2014-01-01

Biphosphonate-associated maxillary bone osteonecrosis (BPMO) is a complication related to nitrogen-containing biphosphonate therapy. This adverse effect occasionally appears in patients who are administered biphosphonates through intravenous infusion for the treatment of cancer involving bone metastases. It can also present, in a lesser degree, in patients who take these drugs orally for the treatment of osteoporosis. Lately, there has been an increase in the number of cases of osteopenia and osteoporosis due to the increasing life expectancy of the world’s population. In our country, a risk group composed mainly of older women who have been diagnosed with osteopenia or osteoporosis, and submitted to the continuous action of oral biphosphonates, is emerging. In this paper we present 18 cases of BPMO associated to the use of oral biphosphonates, diagnosed and treated in the Department of Stomatology of the School or Dentistry at Universidad Nacional de Rosario, Argentina. A protocol was designed in which the following information was recorded: age and sex of the patients, the original disease which led to therapy with oral biphosphonates, the drugs used and the period in which those drugs were administered, the clinical features and location of the lesions, together with triggering factors. Key words:Maxillary osteonecrosis, mandibular osteonecrosis, oral biphosphonates, alendronate, ibandronate. PMID:25674321

The objectives of this study were to determine (i) the prevalence and the copy numbers of oral human papilloma virus type 16 (HPV-16) in HIV-infected patients compared with non-HIV controls, and (ii) the effects of antiretroviral therapy (ART) and its duration on the virus. A cross-sectional study was carried out in HIV-infected patients with and without ART and in non-HIV controls. Saliva samples were collected, and the DNA extracted from those samples was used as a template to detect HPV-16 E6 and E7 by quantitative polymerase chain reaction. Student's t-test and ANOVA test were performed to determine the prevalence rates among groups. Forty-nine HIV-infected patients: 37 on ART (age range, 23-54 years; mean, 37 years), 12 not on ART (age range, 20-40 years; mean, 31 years), and 20 non-HIV controls (age range, 19-53 years; mean, 31 years) were enrolled. The prevalence of oral HPV-16 infection and the copy numbers of the virus were significantly higher in HIV-infected patients than in non-HIV controls when using E6 assay (geometric mean = 10696 vs. 563 copies/10(5) cells, P < 0.001), but not E7 assay. No significant difference was observed between those who were and were not on ART. Long-term use of ART did not significantly change the prevalence of oral HPV-16 infection and the copy numbers of the virus (P = 0.567). We conclude that the prevalence of oral HPV-16 infection and the copy numbers of the virus are increased by HIV infection. Neither the use of ART nor its duration significantly affected the virus. © 2011 John Wiley & Sons A/S.

The high prevalence of dysphagia after stroke leads to increased mortality, and cerebral reperfusion therapy has been effective in reducing neurologic deficits. The aim of this study was to investigate the severity and evolution of dysphagia and the occurrence of pneumonia in patients submitted to cerebral reperfusion therapy. Seventy ischemic stroke patients were evaluated. Of these, 35 patients (group 1) were submitted to cerebral reperfusion therapy and 35 (group 2) did not receive thrombolytic treatment. The following were evaluated: severity of dysphagia by means of videofluoroscopy, evolution of oral intake rate by means of the Functional Oral Intake Scale, and the occurrence of pneumonia by international protocol. The relation between the severity of dysphagia and the occurrence of pneumonia with the treatment was evaluated through the chi-square test; the daily oral intake rate and its relation to the treatment were assessed by the Mann-Whitney test and considered significant if P is less than .05. The moderate and severe degrees of dysphagia were more frequent (P=.013) among the patients who were not submitted to cerebral reperfusion therapy. The daily oral intake evolved independently of the treatment type, without statistical significance when compared between the groups, whereas pneumonia occurred more frequently in group 2 (28%) in relation to group 1 (11%) and was associated with the worst degrees of dysphagia (P=.045). We can conclude that there is improvement in the oral intake rate in both groups, with lower severity of dysphagia and occurrence of pneumonia in ischemic stroke patients submitted to cerebral reperfusion therapy.

The incidence of oral cancer remains high in both Asian and Western countries. Several risk factors associated with development of oral cancer are now well-known, including tobacco chewing, smoking, and alcohol consumption. Cancerous risk factors may cause many genetic events through chromosomal alteration or mutations in genetic material and lead to progression and development of oral cancer through histological progress, carcinogenesis. Oral squamous carcinogenesis is a multistep process in which multiple genetic events occur that alter the normal functions of proto-oncogenes/oncogenes and tumor suppressor genes. Furthermore, these gene alterations can deregulate the normal activity such as increase in the production of growth factors (transforming growth factor-α [TGF-α], TGF-β, platelet-derived growth factor, etc.) or numbers of cell surface receptors (epidermal growth factor receptor, G-protein-coupled receptor, etc.), enhanced intracellular messenger signaling and mutated production of transcription factors (ras gene family, c-myc gene) which results disturb to tightly regulated signaling pathways of normal cell. Several oncogenes and tumor suppressor genes have been implicated in oral cancer especially cyclin family, ras, PRAD-1, cyclin-dependent kinase inhibitors, p53 and RB1. Viral infections, particularly with oncogenic human papilloma virus subtype (16 and 18) and Epstein-Barr virus have tumorigenic effect on oral epithelia. Worldwide, this is an urgent need to initiate oral cancer research programs at molecular and genetic level which investigates the causes of genetic and molecular defect, responsible for malignancy. This approach may lead to development of target dependent tumor-specific drugs and appropriate gene therapy.

The antifungal drug therapy often employed to treat paracoccidiodomycosis (PCM), an important neglected fungal systemic infection, leads to offensive adverse effects, besides being very long-lasting. In addition, PCM compromises the oral health of patients by leading to oral lesions that are very painful and disabling. In that way, photodynamic therapy (PDT) arises as a new promising adjuvant treatment for inactivating Paracoccidioides brasiliensis (Pb), the responsible fungus for PCM, and also for helping the patients to deal with such debilitating oral lesions. PDT has been linked to an improved microbial killing, also presenting the advantage of not inducing immediate microbial resistance such as drugs. For the present study, we investigated the generation of reactive oxygen species (ROS) by using the fluorescent probes hydroxyphenyl fluorescein (HPF) and aminophenyl fluorescein (APF) after toluidine blue (TBO-37.5 mg/L)-mediated PDT (660 nm, 40 mW, and 0.04 cm 2 spot area) and the action of TBO-PDT upon Pb cultures grown for 7 or 15 days in semisolid Fava Netto's culture medium; we also targeted oral PCM manifestations by reporting the first clinical cases (three patients) to receive topic PDT for such purpose. We were able to show a significant generation of hydroxyl radicals and hypochlorite after TBO-PDT with doses around 90 J/cm 2 ; such ROS generation was particularly useful to attack and inactivate Pb colonies at 7 and 15 days. All three patients reported herein related an immediate relief when it came to pain, mouth opening, and also the ability to chew and swallow. As extracted from our clinical results, which are in fact based on in vitro outcomes, TBO-PDT is a very safe, inexpensive, and promising therapy for the oral manifestations of PCM.

Oral cancer is the eleventh most common malignancy in the world, with squamous cell carcinoma being a predominant histologic type. The highest incidence is observed in India, Australia, Brazil, France and South Africa. In Europe the most affected regions are France, French-language cantons of Switzerland, northern Italy and countries of the Middle-East Europe. In most regions cancer is much more common in man. Oral cancer accounts for 1.34% of all registered malignant tumors in Poland in 2008. Etiology of the oral squamous cell carcinoma is complex. The most important risk factors, especially in well-developed countries are tobacco smoking and alcohol exposure. Alcohol promotes cancer development not only administered as a stimulant but also as a component of mouthwashes. Betel chewing, human papilloma virus infection, deficiency of vitamin A, riboflavin and iron, poor mouth hygiene and immunosuppressive therapy are also associated with higher incidence of oral carcinoma. More recently, relation between individual increased susceptibility to oral cancer and some genes polymorphisms, especially those encoding cytokines and enzymes engaged in alcohol metabolism has been found.
