ABSTRACT During the state of immune vulnerability in hematopoietic stem cell transplantation (HSCT), the patient has an increased risk of developing a vast number of complications, including severe problems in the oral cavity. These situations require professional oral care to act in the diagnosis and treatment of these conditions, as well as to develop prevention protocols to minimize patient's complications. Oral mucositis, opportunistic infections, bleeding, specific microbiota, taste, and salivary alterations are complications that can occur during HSCT and interfere with various aspects, such as pain control, oral intake, nutrition, bacteremia and sepsis, days of hospitalization and morbidity. Several guidelines have been published to address the role of professional oral care during the HSCT, we describe a consensus regarding these recommendations.
ABSTRACT The oral involvement in the Hematopoietic Stem Cell Transplantation is well described in the literature. The goal of the dental treatment and management of the oral lesions related to the HSCT is to reduce the harm caused by preexisting oral infection or even the worsening of oral acute/chronic GVHD and late effects. The aim of this guideline was to discuss the dental management of patients subjected to HSCT, considering three phases of the HSCT: pre-HSCT, acute phase, and late phase. The literature published from 2010 to 2020 was reviewed in order to identify dental interventions in this patient population. The selected papers were divided into three groups: pre-HSCT, acute and late, and were reviewed by the SBTMO Dental Committee's members. When necessary, an expertise opinion was considered for better translating the guideline recommendations to our population dental characteristics. This manuscript focused on the pre-HSCT dental management. The objective of the pre-HSCT dental management is to identify possible dental situations that On behalf of the Dental Committee of the Brazilian Society of Gene Therapy and Bone Marrow Transplantation (SBTMO) can worsening during the acute phase after the HSCT. Each guideline recommendations were made considering the Dentistry Specialties. The clinical consensus on dental management prior to HSCT provides professional health caregivers with clinical setting-specific information to help with the management of dental problems in patients to be subjected to HSCT.
ABSTRACT Patients undergoing hematopoietic stem cell transplantation (HSCT) might present acute and late toxicities and the oral tissues are frequently affected. With the survival increasing, patients show late and long-term morbidities, and there is an important association between the general and the oral health. The first and second parts of this Consensus have showed the importance of the adequacy of oral health in the pre-HSCT, and the main alterations and oral care during the period of admission for HSCT. This third part aims to review specific themes of post-HSCT dental care, such as graft-versus-host disease (GVHD) and the pediatric patient. It also aims to review pertinent subjects, both during the HSCT period and post-HSCT, concerning quality of life, pain, cost-effectiveness, and remote care. Based on this review, it is evident the importance of the work of the dental surgeon (DS) in the follow-up and treatment of the HSCT patient, always collaborating with the whole multidisciplinary team.

OBJECTIVES: To assess halitosis parameters using OralChroma™ and the correlation with salivary flow, oral hygiene index, radiation dose, and tongue-coating index among irradiated head and neck cancer patients compared to patients without cancer. MATERIALS AND METHODS: This cross-sectional study enrolled irradiated and non-irradiated patients divided into two groups. Hydrogen sulfide, methyl mercaptan, and dimethyl sulfide (DMS) levels were measured using a gas chromatograph, and sialometry was performed. The tongue-coating index and simplified oral hygiene index were also assessed. RESULTS: Thirty-eight patients were allocated to each group. Volatile sulfur compound levels were above the thresholds in both groups. Non-irradiated individuals showed higher levels of hydrogen sulfide and dimethyl sulfide. Patients with asialia had an inexpressive tongue-coating index and increased dimethyl sulfide levels. A decrease in salivary flow rate was followed by a significant increase in volatile sulfur compound levels. Higher doses of radiation to the submandibular salivary glands were associated with higher concentrations of sulfide and methyl mercaptan. CONCLUSIONS: Head and neck radiotherapy may be important in the development of halitosis. Irradiated patients with asialia presented insignificant lingual biofilm. Consequently, lower levels of volatile sulfur compounds were detected in this group. Asialia, a severe radiation-induced hyposalivation, impacted the levels of DMS (extraoral origin).

To investigate similarities in the gene profile of Oral Lichen Planus and Oral Squamous Cell Carcinoma that may justify a carcinogenic potential, we analyzed the gene expression signatures of Oral Lichen Planus and Oral Squamous Cell Carcinoma in early and advanced stages. Based on gene expression data from public databases, we used a bioinformatics approach to compare expression profiles, estimate immune infiltrate composition, identify differentially and co-expressed genes, and propose putative therapeutic targets and associated drugs. Our results revealed gene expression patterns related to processes of keratinization, keratinocyte differentiation, cell proliferation and immune response in common between Oral Lichen Planus and early and advanced Oral Squamous Cell Carcinoma, with the cornified envelope formation and antigen processing cross-presentation pathways in common between Oral Lichen Planus and early Oral Squamous Cell Carcinoma. Together, these results reveal that key tumor suppressors and oncogenes such as PI3, SPRR1B and KRT17, as well as genes associated with different immune processes such as CXCL13, HIF1A and IL1B are dysregulated in OLP.

Copaiba oleoresin has been related to properties including healing and anti-inflammatory effects, making it a potential candidate to treat oral lesions. We aimed to define the benefits related to the anti-inflammatory and healing capacity of Copaiba-based formulations on the oral cavity. This is a systematic review, conducted in PubMed, Web of Science, Scopus, Embase, Scielo, Cochrane Library, BVS, and Google Scholar databases selecting full articles in English, Portuguese, or Spanish, until March 3rd, 2021. Pre-clinical, clinical, or randomized clinical trials, cohort and case-control in vivo studies were included; studies with other designs, in vitro, and those that did not match the PICO question were excluded (PROSPERO: CRD42021244938). Data was collected and synthesized descriptively through a specific form. The risk of bias was evaluated by SYRCLE's RoB Tool. So, five studies were included. Two reported beneficial wound healing effects, such as early reduction in the wound area and greater immature bone formation in the rats' mandibles; and two related benefic anti-inflammatory effects, like reduced acute inflammatory reaction and more advanced tissue repair stage, early formation of collagen fibrils, with greater quantity, thickness and better organization, and more expressive anti-inflammatory activity, reduction of the edema intensity and the CD68 + macrophages concentration. Based on the articles, benefits related to the wound healing and anti-inflammatory effects in the oral cavity of rats treated with Copaiba oleoresin were suggested. However, due to the limited data, future studies are necessary, especially clinical ones.
Maxillofacial metastases are rare but represent advanced disease progression and a poor prognosis. The primary purpose of this article is to describe a patient with previously diagnosed and treated invasive ductal breast carcinoma who developed a metastatic lesion in the maxillary gingiva. In addition, this article presents a brief literature review of case reports on metastatic breast cancer manifestations in the gingiva. In the present case, a 68-year-old woman had been diagnosed and treated for invasive ductal breast carcinoma. At the 6-month follow-up after treatment for breast cancer, she complained of pain in the right leg and spine, swelling in the right arm associated with redness, and a nodular growth in the maxillary gingiva that was painful, friable, and associated with tooth mobility. Imaging examinations and microscopic analysis of an oral biopsy specimen revealed disease progression to the oral cavity, femur, lung, and brain. Because of the advanced disease, the patient died within a few weeks. The literature review identified 6 articles that reported varied clinical presentations of metastatic breast cancer in the gingiva. Invasive ductal carcinoma was the most common histologic type. Routine dental follow-up of patients with cancer is essential for the identification and diagnosis of oral lesions to ensure early intervention for lesions that may be distant metastases mimicking benign lesions.

OBJECTIVE: The aim of this study was to evaluate patients with complete response of oral chronic graft-versus-host disease to immunosuppressive treatment. METHODS: A total of 29 patients submitted to allogeneic hematopoietic stem cell transplantation, with oral chronic graft-versus-host disease, were enrolled in this retrospective study, from September 2012 to February 2018. Patients were treated with combined topical dexamethasone solution and topical tacrolimus ointment, combined topical dexamethasone and topical tacrolimus, systemic immunosuppressive medication, and topical dexamethasone only. RESULTS: The mean time of complete response of lichenoid lesions, erythema, and ulcers using dexamethasone and systemic immunosuppressive medication was of 105, 42 and 42 days, respectively (p=0.013).When we associated dexamethasone, tacrolimus and systemic immunosuppressive medication, the mean time of complete response of lichenoid lesions, erythema and ulcers was of 91,84 and 77 days (p=0.011). When dexamethasone was used alone, the mean time of complete response of lichenoid lesions, erythema and ulcers was 182, 140, 21 days, respectively (p=0.042). CONCLUSION: Our study shows that lichenoid lesions require more time to heal. Notably, lichenoid lesions tend to respond better to dexamethasone combined with tacrolimus and systemic immunosuppressive medication, whereas erythema and ulcers respond better to dexamethasone combined with systemic immunosuppressive medication and dexamethasone only, respectively.

Thermal burns of the oral cavity usually arise from ingestion of hot foods or beverages. A 38-year-old female patient presented with two painful ulcerative erythematous patches of the palate. The patient was consulted on the same day lesions appeared. Medical history was unremarkable. Clinically significant self-inflicted injuries may result in wide ulcers in the mouth and usually do not take less than 2 weeks to heal, whereas our patient, treated with low-level laser therapy, had a complete response in day 4, after 2 days of treatment. The fact that multiple lesions were present signaled against the World Health Organization exclusion diagnosis of erythroplakia for red patches. A traumatic ulcer, regardless of its cause of origin, usually heals within 2 weeks, after the source of injury is resolved. A thermal burn in the oral cavity usually takes longer than that to heal, but whenever this time frame is not respected, the suspicion of a potentially malignant disorder should always arise, and a biopsy should be performed. The present case showed two painful thermal burns with great results in terms of speeding up the relieve of symptoms and healing time with soft laser as opposed to the traditional treatment with oral topical corticosteroid.
OBJECTIVES: This study aim was to review cases of acinic cell carcinoma (the main differential diagnosis of secretory carcinoma) that were diagnosed and treated at the National Cancer Institute of Brazil (INCA) between 1996 and 2016. The primary objective was to identify underdiagnosed cases of secretory carcinoma via a clinical, immunopathological and molecular reassessment. MATERIALS AND METHODS: This is a cross sectional study, with retrospective data collection from medical records and histological specimen review, with staining for periodic acid-Schiff (PAS) and PAS with diastase, immunohistochemistry for S-100, mammaglobin, and DOG-1, and droplet digital RT-PCR for ETV6-NTRK3. The Research Ethics Committee approved this study, and the patients allowed their participation through informed consent. RESULTS: Eighty-three cases of acinic cell carcinoma were diagnosed and treated in the specified period at INCA, of which, seven had their diagnosis changed to secretory carcinoma. CONCLUSION: The present study adds seven cases of secretory carcinoma to the literature, contributing to a better understanding of the epidemiological, histological, immunohistochemical and molecular characteristics of this recently described tumor. Also, the use of a comprehensive diagnostic approach, including immunohistochemical and molecular methods, along with classical morphological studies, allowed the reclassification of acinic cell carcinoma to secretory carcinoma.

OBJECTIVE: The aim of this systematic review was to describe the epidemiology, diagnostic criteria, differential diagnosis, treatment, prognostic factors, and treatment outcomes of secretory carcinoma. STUDY DESIGN: A comprehensive search of Lilacs, PubMed, Science Direct, and Web of Science databases was conducted to identify all case reports, letter to the editor, and histopathologic reclassifications regarding salivary gland secretory carcinoma published in English, Spanish, French, and Portuguese. RESULTS: The final analysis included 119 studies, which totaled 642 secretory carcinoma diagnoses, with 239 case reports and 403 diagnostic reclassifications, mostly in the United States. The age range was 5 to 87 years, and cases were predominantly in males (58.7%) and mostly affecting the parotid glands (73.7%). The disease usually presents as a slow-growing, painless mass. The main differential diagnosis is acinic cell carcinoma, and the tumor is usually treated with surgery. The prognosis is considered favorable, although there have been reports of local recurrences, distant metastases, and deaths. CONCLUSIONS: It is important that clinicians become aware of this salivary gland neoplasm and report clinical data, clinical course, management and long-term follow-up. There is an urgent need to conduct more clinical trials, especially on tropomyosin receptor kinase (TRK) inhibitors and other potential target therapy modalities.
