Patient communication protocols for sexually transmitted infections: A systematic review

AIMS

We conducted a systematic review of post-test communication protocols and observational studies regarding counseling for a positive sexually transmitted infection (STI) result and also discuss the role of dental specialist (e.g., oral medicine) in this sense.

METHODS AND RESULTS

The search process followed the parameters of PRISMA 2020 guidelines. MEDLINE/PubMed, Web of Science, Scopus, EMBASE, and LILACS were consulted with a specific search strategy for each one. Additionally, the references of the included studies, grey literature, and experts were consulted. Four protocols and 18 observational studies were included in this systematic review, published between 1997 and 2022 in the Americas and Europe. The communication protocols emphasized the importance of conducting personal and private discussions with patients to address their fears and questions. Among the observational studies, 56% indicated that post-test counseling was either ineffective or absent. Furthermore, 22% of the studies used telephone communication to deliver results to patients.

CONCLUSIONS

Our study showed that the communication process of a positive STI result affects the patients in several aspects, as treatment adherence and their relationship with the community. Nevertheless, this process of STI post-test communication seems to be flawed, which brings potential negative effects to patients.

Is medication-related osteonecrosis of the jaw associated with tumor necrosis factor-α inhibition?

OBJECTIVE

This article reviews the literature and evidence of the association of medication-related osteonecrosis of the jaw with tumor necrosis factor-α inhibition.

METHODS

A systematic review was performed using electronic databases (PubMed, MEDLINE, and Embase) using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Key terms were used in the search. No restrictions were placed on publication status. Selection criteria comprised all levels of available evidence. Articles in the English language were selected up to and including July 2020. Reference lists of relevant studies were searched for additional articles. Articles were selected on the basis of inclusion and exclusion criteria. Findings from eligible studies were extracted by one reviewer and confirmed by a second. Disagreements were settled through discussion.

RESULTS

The initial search of the key terms yielded 2107 articles. There were 1192 articles remaining after removal of duplicates and addition of 6 articles that were hand-selected from among reference lists of relevant studies. There were 12 eligible articles after screening. The full texts were read, and 5 articles were included on the basis of inclusion and exclusion criteria.

CONCLUSIONS

Further research is required to determine an association of medication-related osteonecrosis of the jaw and tumor necrosis factor-α inhibition.

Consequences to patients, clinicians, and manufacturers when very serious adverse drug reactions are identified (1997-2019): A qualitative analysis from the Southern Network on Adverse Reactions (SONAR)

BACKGROUND

Adverse drug/device reactions (ADRs) can result in severe patient harm. We define very serious ADRs as being associated with severe toxicity, as measured on the Common Toxicity Criteria Adverse Events (CTCAE)) scale, following use of drugs or devices with large sales, large financial settlements, and large numbers of injured persons. We report on impacts on patients, clinicians, and manufacturers following very serious ADR reporting.

METHODS

We reviewed clinician identified very serious ADRs published between 1997 and 2019. Drugs and devices associated with reports of very serious ADRs were identified. Included drugs or devices had market removal discussed at Food and Drug Advisory (FDA) Advisory Committee meetings, were published by clinicians, had sales > $1 billion, were associated with CTCAE Grade 4 or 5 toxicity effects, and had either >$1 billion in settlements or >1,000 injured patients. Data sources included journals, Congressional transcripts, and news reports. We reviewed data on: 1) timing of ADR reports, Boxed warnings, and product withdrawals, and 2) patient, clinician, and manufacturer impacts. Binomial analysis was used to compare sales pre- and post-FDA Advisory Committee meetings.

FINDINGS

Twenty very serious ADRs involved fifteen drugs and one device. Legal settlements totaled $38.4 billion for 753,900 injured persons. Eleven of 18 clinicians (61%) reported harms, including verbal threats from manufacturer (five) and loss of a faculty position (one). Annual sales decreased 94% from $29.1 billion pre-FDA meeting to $4.9 billion afterwards (p<0.0018). Manufacturers of four drugs paid $1.7 billion total in criminal fines for failing to inform the FDA and physicians about very serious ADRs. Following FDA approval, the median time to ADR reporting was 7.5 years (Interquartile range 3,13 years). Twelve drugs received Box warnings and one drug received a warning (median, 7.5 years following ADR reporting (IQR 5,11 years). Six drugs and 1 device were withdrawn from marketing (median, 5 years after ADR reporting (IQR 4,6 years)).

INTERPRETATION

Because very serious ADRs impacts are so large, policy makers should consider developing independently funded pharmacovigilance centers of excellence to assist with clinician investigations.

Safety and efficacy of photobiomodulation therapy in oncology: A systematic review

We performed a systematic review of the current literature addressing the safety and efficacy of photobiomodulation therapy (PBMT) in cancer patients. In this systematic review, the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines were used. In vitro, in vivo, and clinical studies, which investigated the effect of PBMT on cell proliferation/differentiation, tumor growth, recurrence rate, and/or overall survival were included. The Medline/PubMed, EMBASE, and Scopus databases were searched through April 2020. A total of 67 studies met the inclusion criteria with 43 in vitro, 15 in vivo, and 9 clinical studies identified. In vitro studies investigating the effect of PBMT on a diverse range of cancer cell lines demonstrated conflicting results. This could be due to the differences in used parameters and the frequency of PBM applications. In vivo studies and clinical trials with a follow‐up period demonstrated that PBMT is safe with regards to tumor growth and patient advantage in the prevention and treatment of specific cancer therapy‐related complications. Current human studies, supported by most animal studies, show safety with PBMT using currently recommended clinical parameters, including in Head & Neck cancer (HNC) in the area of PBMT exposure. A significant and growing literature indicates that PBMT is safe and effective, and may even offer a benefit in patient overall survival. Nevertheless, continuing research is indicated to improve understanding and provide further elucidation of remaining questions regarding PBM use in oncology.

Osteonecrosis of the jaw related to non-antiresorptive medications: a systematic review

INTRODUCTION

The reporting of osteonecrosis of the jaw (ONJ) related to anticancer agents without known antiresorptive properties (non-antiresorptives), such as antiangiogenics, tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors, immune checkpoint inhibitors, and cytotoxic chemotherapy is increasing.

OBJECTIVE

To review characteristics of ONJ in cancer patients receiving non-antiresorptives.

METHODS

A systematic review of the literature between 2009 and 2017 was conducted by the Bone Study Group of MASCC/ISOO.

RESULTS

Of 6249 articles reviewed and from personal communication, 42 ONJ cases related to non-antiresorptives were identified. No gender predilection was noted. Median age was 60 years and ONJ stage 2 was most common, with predilection for posterior mandible. Exposed bone, pain, and infection were common at diagnosis. In comparison to bone targeting agents (BTAs), radiology, histology, and management were similar, with medication often discontinued. Delayed diagnosis (median 8 weeks) was noted. Important differences included earlier time to ONJ onset (median 20 weeks), absence of trigger event (40%), and greater likelihood of healing and shorter healing time (median 8 weeks) as compared to BTA-related ONJ. Gastrointestinal cancers predominated, followed by renal cell carcinomas compared to breast, followed by prostate cancers in BTA-related ONJ, reflecting different medications.

CONCLUSIONS

Data about non-antiresorptive-related ONJ is sparse. This type of ONJ may have better prognosis compared to the BTA-related ONJ, suggested by greater likelihood of healing and shorter healing time. However, the delay in diagnosis highlights the need for more education. This is the first attempt to characterize ONJ associated with different non-antiresorptives, including BRAF and immune checkpoint inhibitors.

Osteonecrosis of the jaw (ONJ) in patients who receive Bone Targeting Agents (BTAs): the power of e-learning

The definition, pathobiology and risk factors of ONJ in cancer patients who receive BTAs are discussed in the recent ecancer module for osteonecrosis of the jaw (http://ecancer.org/education/module/276-osteonecrosis-of-the-jaw.php). ONJ prevention, early diagnosis and management are presented. The critical question of the performance of dental extraction, during BTA therapy, as indicated with the recent studies, is supported. The importance of the collaboration between dental and oncology professionals and the patients is highlighted and can be achieved through appropriate education. The ecancer modules are valuable tools for successful e-learning in medical oncology education, including ONJ.

Comparison of mandibular cortical thickness and QCT-derived bone mineral density (BMD) in survivors of childhood acute lymphoblastic leukemia: a retrospective study

OBJECTIVE

To examine whether panoramic radiograph-determined mandibular cortical thickness correlated with quantitative computed tomography-derived bone mineral density (BMD) in survivors of childhood acute lymphoblastic leukemia (ALL).

METHODS

We identified patients treated for ALL at St. Jude Children's Research Hospital, seen in the After Completion of Therapy (ACT) Clinic between January of 2006 and January of 2014 who had QCT-derived BMD and panoramic radiographs obtained within 1 month of each other. Panoramic radiographs were independently scored by a pediatric radiologist, two pediatric dentists, and a general dentist using the Klemetti technique. We used the Spearman's rank correlation test and the multivariate regression model to investigate the effect of evaluator experience on results.

RESULTS

The study cohort comprised 181 patients with 320 paired studies: 112 (62%) male, 112 (71%) were white. Median age at ALL diagnosis was 6.4 (range, 0-18.8) years. Median age at study was 11.9 (range, 3.3 to 29.4) years. The median average BMD was 154.6 (range, 0.73-256) mg/cc; median QCT Z-score (age and gender adjusted) was -0.875 (range, -5.04 to 3.2). We found very weak association between panoramic radiograph score and both QCT-BMD average (P = 0.53) and QCT Z-score (P = 0.39). Results were not influenced by level of reader experience.

CONCLUSIONS

The Klemetti technique of estimating BMD does not predict BMD deficits in children and young adult survivors of ALL, regardless of reviewer expertise. Alternative methods are needed whereby dental healthcare providers can identify and refer patients at risk for BMD deficits for detailed assessment and intervention.

MASCC/ISOO clinical practice guidelines for the management of mucositis secondary to cancer therapy

BACKGROUND

Mucositis is a highly significant, and sometimes dose‐limiting, toxicity of cancer therapy. The goal of this systematic review was to update the Multinational Association of Supportive Care in Cancer and International Society of Oral Oncology (MASCC/ISOO) Clinical Practice Guidelines for mucositis.

METHODS

A literature search was conducted to identify eligible published articles, based on predefined inclusion/exclusion criteria. Each article was independently reviewed by 2 reviewers. Studies were rated according to the presence of major and minor flaws as per previously published criteria. The body of evidence for each intervention, in each treatment setting, was assigned a level of evidence, based on previously published criteria. Guidelines were developed based on the level of evidence, with 3 possible guideline determinations: recommendation, suggestion, or no guideline possible.

RESULTS

The literature search identified 8279 papers, 1032 of which were retrieved for detailed evaluation based on titles and abstracts. Of these, 570 qualified for final inclusion in the systematic reviews. Sixteen new guidelines were developed for or against the use of various interventions in specific treatment settings. In total, the MASCC/ISOO Mucositis Guidelines now include 32 guidelines: 22 for oral mucositis and 10 for gastrointestinal mucositis. This article describes these updated guidelines.

CONCLUSIONS

The updated MASCC/ISOO Clinical Practice Guidelines for mucositis will help clinicians provide evidence‐based management of mucositis secondary to cancer therapy. Cancer 2014;120:1453–1461. © 2014 The Authors. Cancer published by Wiley Periodicals, Inc. on behalf of American Cancer Society.

Mucositis is a highly significant, and sometimes dose‐limiting, toxicity of cancer therapy. This article presents evidence‐based clinical practice guidelines for the management of mucositis.

Systematic review of laser and other light therapy for the management of oral mucositis in cancer patients

BACKGROUND

The aim of this study was to review the available literature and define clinical practice guidelines for the use of laser and other light therapies for the prevention and treatment of oral mucositis.

METHODS

A systematic review was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology. The body of evidence for each intervention, in each cancer treatment setting, was assigned an evidence level. Based on the evidence level, one of the following three guideline determinations was possible: recommendation, suggestion, and no guideline possible.

RESULTS

A new recommendation was made for low-level laser (wavelength at 650 nm, power of 40 mW, and each square centimeter treated with the required time to a tissue energy dose of 2 J/cm(2) (2 s/point)) for the prevention of oral mucositis in adult patients receiving hematopoietic stem cell transplantation conditioned with high-dose chemotherapy, with or without total body irradiation. A new suggestion was made for low-level laser (wavelength around 632.8 nm) for the prevention of oral mucositis in patients undergoing radiotherapy, without concomitant chemotherapy, for head and neck cancer. No guideline was possible in other populations and for other light sources due to insufficient evidence.

CONCLUSIONS

The increasing evidence in favor of low-level laser therapy allowed for the development of two new guidelines supporting this modality in the populations listed above. Evidence for other populations was also generally encouraging over a range of wavelengths and intensities. However, additional well-designed research is needed to evaluate the efficacy of laser and other light therapies in various cancer treatment settings.

Pharmacovigilance and reporting oversight in US FDA fast-track process: bisphosphonates and osteonecrosis of the jaw

More than half of all serious adverse reactions are identified 7 or more years after a drug receives approval from the US Food and Drug Administration (FDA). In 2002, 9 months after the intravenous bisphosphonate zoledronic acid received regulatory approval for marketing, the FDA received reports of nine patients with cancer, who were treated with zoledronic acid, who unexpectedly developed osteonecrosis of the jaw. During the next 2 years, three oral surgeons described 104 patients with cancer with osteonecrosis of the jaw in the medical literature and identified intravenous bisphosphonate therapy as being common to the care of these patients. In subspecialty medical, radiology, and dental journals, case reports and case series described clinical features of osteonecrosis of the jaw in patients with cancer who were treated with bisphosphonates. Manufacturer-sponsored epidemiological studies reported the first estimates of the incidence of this toxic effect, ranging from 0.1% to 1.8%. By contrast, independent epidemiological efforts from clinicians and the International Myeloma Foundation reported incidence estimates between 5% and 10%. Between 2003 and 2005, warnings about the risks of bisphosphonate-associated osteonecrosis were disseminated by national regulatory agencies, the manufacturers of bisphosphonates, and the International Myeloma Foundation. From 2006, independent clinical recommendations for diagnosis, prevention, and treatment of this toxic effect have been disseminated by manufacturers, national regulatory authorities, the International Myeloma Foundation, and medical specialty organisations. Furthermore, independent efforts by pharmaceutical manufacturers, dental and medical professionals, a non-profit organisation (the International Myeloma Foundation), patients, and regulatory authorities has led to the rapid identification and dissemination of safety information for this serious adverse reaction. Better coordination of safety-related pharmacovigilance initiatives is now needed.

Pathophysiology, risk factors and management of bisphosphonate-associated osteonecrosis of the jaw: Is there a diverse relationship of amino- and non-aminobisphosphonates?

Reports of osteonecrosis of the jaw (ONJ) in patients receiving long-term bisphosphonate therapy have appeared in the literature since 2003. This condition involves avascular necrotic bone in the area of maxilla or mandibula and there may be a secondary infection. Most cases of ONJ have been reported in cancer patients receiving the intravenous aminobisphosphonates zoledronic acid and pamidronate monthly or q 3 week; of note these are also the two most commonly used agents of this class. Risk factors for ONJ include a history of trauma, dental surgery or dental infection and intravenous bisphosphonate administration; in addition, the extent and duration of exposure to bisphosphonates also seem to correlate with the risk. Although a direct causal relationship with bisphosphonates cannot be assumed, these agents may possibly contribute to the development of ONJ by suppression of bone remodeling in the jaw which leads to increased rates of bone mineralisation and accumulation of microfractures. Clodronate, a non-aminobisphosphonate, appears to have a different mechanism of suppressing bone remodeling compared with aminobisphosphonates, and this may explain why few cases of ONJ have been reported with clodronate despite extensive use over the past 20 years; however, the potential of clodronate to reduce the risk of ONJ while providing equivalent clinical benefit to the aminobisphosphonates needs to be substantiated in controlled clinical trials. Use of bisphosphonate therapy should be carefully planned in patients with metastatic bone disease who have risk factors for ONJ, and appropriate preventive measures taken to avoid the development of this condition.

Oral manifestations of Wegener's granulomatosis: a report of three cases and a literature review

BACKGROUND

Hyperplastic granular gingivitis or "strawberry gingivitis" is a rare manifestation of Wegener's granulomatosis (WG), but it is nearly pathognomonic for this multisystem autoimmune vasculitis. The dentist may be the first health care professional to see patients with symptoms and findings of this condition. Early diagnosis and treatment is the most important factor in the management of this potentially fatal disease.

METHODS

The authors present three case reports that demonstrate the disease spectrum and conducted a literature review focused on current understanding of this disease.

RESULTS

The first patient had only the classic gingival manifestations of the disease. The second patient had simultaneous typical gingival lesions, as well as dermatologic findings. The third patient had an atypical oral presentation of aphthous ulcers and erythematous gingiva, as well as respiratory and genital involvement. Reaching a definitive diagnosis sometimes is challenging owing to the subtle onset of the disease and variable clinical and laboratory findings.

CONCLUSION AND CLINICAL IMPLICATIONS

Clinicians should be familiar with the broad variety of oral and systemic components of WG, as well as strategies to facilitate prompt disease recognition and to provide continued oral health care to these medically complex patients.

Promulgation of guidelines for mucositis management: educating health care professionals and patients

BACKGROUND

The Multinational Association for Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) Mucositis and Patient and Professional Education Study Groups are collaborating to improve the promulgation of the updated mucositis management guidelines. The initial step in the collaboration was to survey cancer care health professionals to determine their awareness of the original 2004 guidelines and their opinions on the usefulness of patient educational materials based on the guidelines.

MATERIALS AND METHODS

The authors surveyed four samples (three US and one European) of cancer health care professionals attending three cancer-related professional conferences between May and July 2005 using a ten-item questionnaire in both paper-and-pencil and web-based formats. Data were compiled and analyzed using descriptive statistics.

RESULTS

All respondents were generally aware of the importance of mucositis as a treatment-limiting toxicity with life-threatening complications and endorsed regular oral assessment and dental care practices. Only about one third of the US respondents were aware of the 2004 guidelines in contrast to 80% of the European respondents. A majority of respondents across all four surveys (66-93%) felt strongly that educational materials based on the guidelines were needed and that they would use them, while a smaller number (7-29%) indicated they might use them if a patient had a problem with mucositis.

CONCLUSIONS

Awareness of the guidelines remains limited in the US, and use of the guidelines worldwide is minimal. The Mucositis and Patient and Professional Education Study Groups have developed a set of strategies to enhance dissemination, awareness, and use of the updated guidelines and to promote patient education based on the guidelines. Future work will focus on implementation and evaluation of the guidelines in clinical practice.

Thalidomide treatment of mucosal ulcerations in HIV infection

Percutaneous and mucous membrane exposure protocol in a southeastern dental school

A southeastern dental educational institution formalized a Percutaneous and Mucous Membrane Exposure Protocol in 1990. This article outlines the development, implementation, and administration of the protocol including risk assessment and rationale for testing health care workers and source persons. Pretest and posttest counseling for HIV testing is also discussed.

Findings in 50 AIDS virus-infected patients with positive oral Candida cultures

Oral candidiasis is a common complication of HIV-infected-individuals. The purpose of this study was to evaluate clinical and laboratory findings to assess the impact and efficacy of antifungal treatment. This preliminary report describes findings in 50 HIV-positive, candida culture-positive subjects (49 males, 1 female; mean age: 39 years). The group had been known HIV-positive for a mean of 28 months, and 19 met the CDC/WHO definition for AIDS (63%, KS, 21% PCP). Thirty-four of the fifty patients had oral signs of candidiasis, with almost half having both atrophic (red) and pseudomembranous (white) components. In quantitating the cultures, the higher colony forming unit counts in general were correlated with clinical signs and pain. The other most common oral manifestations were periodontal disease, hairy leukoplakia and xerostomia. The most common candida species was albicans (84%). Response to initial antifungal therapy was satisfactory clinically, but erratic regarding CFU quantitation, species changes, and bacterial emergence. In summary, oral candidiasis is a complex infection with uncertainties as to the significance of quantitation and achieving control.

Clinical efficacy of prednisone in the treatment of patients with oral inflammatory ulcerative diseases: a study of fifty-five patients

An objective evaluation of 55 patients with chronic vesiculoerosive oral diseases was made to compare the beneficial and adverse effects of prednisone treatment. Patients were divided into groups of high, intermediate, and low drug dosages, as well as short and long periods of administration. Prednisone benefited 49 patients in spite of the fact that 55% had some adverse side effects. The duration of prednisone administration appeared to have a larger impact on side effects than the daily amount given. The most common side effects were gastrointestinal disturbances, mood alterations, polyuria and insomnia. There were no significant changes in blood pressure, blood sugar level, weight, or white blood cell counts. This study confirmed that systemic prednisone is a useful and beneficial treatment modality for patients with chronic oral inflammatory diseases.

Adverse side effects associated with prednisone in the treatment of patients with oral inflammatory ulcerative diseases

Systemic glucocorticoids in the form of prednisone have been effective in reducing signs and symptoms in a variety of acute and chronic oral inflammatory diseases. In the 101 patients prospectively studied, the benefits from prednisone treatment far outweighed the adverse side effects, which occurred in 61 patients. However, none of the adverse side effects was severe enough to require cessation of the prednisone. The adverse effects, which could be minimized by reducing the dosage in most instances, were primarily related to treatment that persisted for more than two weeks. Fluid retention or bloating was the most common symptom, and insomnia was the chief side effect in those patients receiving short-term treatment (less than two weeks). Blood sugar, blood pressure, weight, and white blood cell counts were not meaningfully altered. Variables in patients' drug response and side effects precluded formulation of precise prednisone dosages that would allow predictive outcomes.

Toluidine blue staining in the detection of oral precancerous and malignant lesions

One hundred thirty-two consecutive patients suspected of having malignant or precancerous oral lesions were studied by comparing toluidine blue dye uptake clinically with a simultaneous biopsy. The histopathologic diagnosis confirmed 57 squamous carcinomas, 42 epithelial dysplasias, and 33 benign mucosal changes. Overall accuracy of the toluidine blue uptake was 91%. In the dysplastic and malignant lesions the false negatives were 2%, and there were 30% false positives in the benign lesions. It was concluded that toluidine blue staining is a useful adjunct to careful examination, clinical judgment, and biopsy.
