ABSTRACT

ABSTRACT Peri-implant diseases, caused by bacteria from biofilm related to dental implants, are one of the main causes of late loss of implants. In this sense, peri-implant diseases are divided into peri-implant mucositis, when it affects only the soft tissues, and peri-implantitis, when there is a bone involvement, which can lead to the failure of dental implant therapy. Thus, biofilm removal is essential for peri-implant health, allowing long-term success in implant therapy. To improve the visualization of oral biofilm, which is usually transparent or colorless, disclosing agents have been routinely used. However, disclosing agents have allergenic potential and can cause staining extrinsically in restorative and prosthetic materials, leading to aesthetic impairment. Thus, the use of fluorescence has been studied as an alternative for visualization of oral biofilm. Therefore, this report describes the use of wide-field optical fluorescence for visualization of oral biofilm associated with implants and teeth, in a routine appointment and follow-up of a partially edentulous patient with peri-implant mucositis. In addition, this report showed wide-field optical fluorescence can be used in a clinical routine of care of patients with dental implants. In this sense, wide-field optical fluorescence allowed easy and immediate visualization of the mature oral biofilm for its adequate removal, evaluation of the quality of restoration to sealing of screw access-hole of implant and identification of cariogenic lesions, without risk of allergic reactions or staining of prostheses and restorations.


RESUMO Doenças peri-implantares, causadas por bactérias de biofilme relacionadas a implantes dentários, são uma das principais causas de perda tardia de implantes. Nesse sentido, as doenças peri-implantares são divididas em mucosite peri-implantar, quando afeta apenas tecidos moles, e peri-implantite, quando há comprometimento ósseo, o que pode levar ao fracasso da terapia com implantes dentários. Assim, a remoção do biofilme é essencial para a saúde peri-implantar, permitindo sucesso a longo prazo na terapia com implantes. A fim de melhorar a visualização do biofilme oral, que geralmente é transparente ou incolor, agentes reveladores têm sido rotineiramente utilizados. No entanto, esses agentes têm potencial alergênico e podem causar manchas extrinsecamente em materiais restauradores e protéticos, levando a prejuízo estético. Assim, o uso da fluorescência tem sido estudado como alternativa para visualização do biofilme oral. Este relato descreve o uso da fluorescência óptica de campo amplo para visualização do biofilme oral associado a implantes e dentes em uma consulta de acompanhamento de rotina de uma paciente parcialmente edêntula com mucosite peri-implantar. Além disso, este relato evidenciou que a fluorescência óptica de campo amplo pode ser utilizada dentro da rotina clínica de atendimento de pacientes com implantes dentários. Nesse sentido, a fluorescência óptica de campo amplo permitiu a visualização fácil e imediata do biofilme oral maduro para sua remoção adequada, a avaliação da qualidade da restauração do selamento do orifício de acesso do parafuso do implante e a identificação de lesões cariogênicas, sem risco de reações alérgicas ou manchamento de próteses e restaurações.

ABSTRACT

Peri-implantitis is one of the leading causes of implant failure and loss, and its early diagnosis is not currently feasible due to the low sensitivity of currents methods. In the current exploratory cross-sectional study, we explored the diagnostic potential of lymphocyte B and Th17-chemotactic cytokine levels in peri-implant crevicular fluid (PICF) in 54 patients with healthy, peri-mucositis, or peri-implantitis implants. Peri-implant crevicular fluid was collected, and the levels of the molecules under study were quantified by Luminex assay. The concentrations of CCL-20 MIP-3 alpha, BAFF/BLYS, RANKL and OPG concentration in PICF were analyzed in the context of patient and clinical variables (smoking status, history of periodontitis, periodontal diagnosis, implant survival, suppuration, bleeding on probing, periodontal probing depth, clinical attachment level, mean of implant probing depth, and plaque index). Patients with peri-implantitis, appear to have an overregulation of the RANKL/BAFF-BLyS axis. This phenomenon needs to be investigated in depth in further studies with a larger sample size.


La periimplantitis es una de las principales causas de falla y pérdida del implante, y su diagnóstico temprano no es factible debido a la baja sensibilidad de los métodos actuales. En este estudio transversal exploratorio, se estudió el potencial diagnóstico de los niveles de citocinas quimiotácticas de linfocitos B y Th17 en el líquido crevicular periimplantario (LCPI) en 54 pacientes con implantes sanos, peri-mucositis o periimplantitis. Se recogió líquido crevicular periimplantario y se cuantificaron los niveles de las moléculas estudiadas mediante Luminex assay. Las concentraciones de CCL-20 MIP-3 alfa, BAFF/BLYS, RANKL y la concentración de OPG en LCPI se analizaron en el contexto de las variables clínicas y del paciente (tabaquismo, antecedentes de periodontitis, diagnóstico periodontal, supervivencia del implante, supuración, sangrado al sondaje, profundidad de sondeo periodontal, nivel de inserción clínica, media de la profundidad de sondeo del implante e índice de placa). Los pacientes con periimplantitis parecen tener una sobrerregulación del eje RANKL/BAFF-BLyS. Este fenómeno debe investigarse en profundidad en futuros estudios con un tamaño de muestra mayor.

ABSTRACT

Abstract Oral mucositis is a common inflammatory complication among patients with cancer. This study evaluated the histopathological, stereological, and antioxidant markers of 2% eucalyptus extract in induced oral mucositis in male golden hamsters. In this animal study, oral mucositis was induced in 30 male golden hamsters by 5-FU (60 mg/kg) on days 0, 5, and 10 of the study. The cheek pouch was scratched with a sterile needle once daily on days 3 and 4. On days 14-17, 2% eucalyptus hydroalcoholic extract gel and Calendula officinalis extract gel groups were treated and then compared with a non-treated control group. The histopathological and stereological scores and the pouch content of malondialdehyde, as well as the activities of glutathione and myeloperoxidase in the pouch tissue, were evaluated. Histopathologic scores of oral mucositis were lower in the eucalyptus gel group than those of the calendula and control groups (p<0.05). Also, a lower malondialdehyde level and higher myeloperoxidase and glutathione activities were detected in the eucalyptus group in comparison to the calendula and control groups (p<0.001). The thickness of the mucosa and submucosa increased in the eucalyptus group. The numerical density of the fibroblast and the volume density of the collagen significantly increased in the eucalyptus group. In conclusion, the use of eucalyptus hydroalcoholic extract may be associated with reduced intensity of oral mucositis, diminished concentration of malondialdehyde, increased activity of myeloperoxidase and glutathione, increased volume of mucosa and submucosa, increased fibroblast and collagen in the induced oral mucositis in golden hamsters undergoing 5-FU consumption.


Resumo A mucosite oral é uma complicação inflamatória comum em pacientes com câncer. Este estudo avaliou os marcadores histopatológicos, estereológicos e antioxidantes de Eucalyptus 2% na mucosite oral induzida em hamsters dourados machos. Neste estudo em animais, a mucosite oral foi induzida em 30 hamsters golden masculinos por 5-FU (60 mg / kg) nos dias 0, 5 e 10 do estudo. A bolsa da bochecha foi arranhada com uma agulha estéril uma vez ao dia nos dias 3 e 4. Nos dias 14 a 17, os grupos de gel de eucalipto a 2% e curativos à base de gel foram tratados e comparados com um grupo controle. Foram avaliados os escores histopatológicos e estereológicos e o conteúdo de malondialdeído na bolsa, bem como as atividades de glutationa e mieloperoxidase no tecido da bolsa. Os escores histopatológicos de mucosite foram menores no grupo de gel de eucalipto a 2% do que os do gel e do grupo controle (p <0,05). Além disso, um nível mais baixo de malondialdeído e maiores atividades de mieloperoxidase e glutationa foram detectadas no grupo tratado com eucalipto em comparação aos grupos à base de gel e controle (p <0,001). A espessura da mucosa e submucosa aumentou no grupo Eucalyptus. A densidade numérica do fibroblasto e a densidade do volume do colágeno aumentaram significativamente nos grupos tratados com eucalipto. Em conclusão, o uso do extrato hidroalcoólico de Eucalyptus pode estar associado a menor intensidade de mucosite oral, diminuição da concentração de malondialdeído, aumento da atividade de mieloperoxidase e glutationa, aumento do volume de mucosa e submucosa, aumento de fibroblastos e colágeno na mucosite oral induzida em hamsters dourados em consumo de 5 UF.

ABSTRACT

La mucositis es una respuesta inflamatoria del epitelio de la mucosa a los efectos citotóxicos de la quimioterapia y la radioterapia, que causan dolor y ulceración oral severa. En los estudios de los últimos años se ha propuesto el uso de la miel en el manejo de la mucositis oral inducida por quimioterapia y radioterapia en pacientes pediátricos. La miel reduce la severidad y duración de la mucositis, reduce el dolor y es un producto agradable a los niños. Por tanto, podría ser un producto eficaz tanto en la profilaxis como en el tratamiento de la mucositis oral. Sin embargo, la pequeña cantidad de investigaciones realizadas en humanos no es suficiente para establecer recomendaciones generalizadas. Por ello, se debe aumentar las investigaciones en este campo. Con ello se podrá examinar la eficacia y posibles complicaciones a corto y largo plazo, explorar su posible efecto sinérgico con otras terapias, analizar su rentabilidad económica y el tipo de miel más adecuado. De esta forma, los profesionales sanitarios podrán ofrecer a los pacientes pediátricos los mejores cuidados basados en las últimas evidencias científicas demostradas.


Mucositis is an inflammatory response of the mucosal epithelium to the cytotoxic effects of chemotherapy and radiation therapy, causing pain and severe oral ulceration. In the studies of recent years, the use of honey has been proposed in the management of oral mucositis induced by chemotherapy and radiotherapy in pediatric patients. Honey reduces the severity and duration of mucositis, reduces pain and is a child-friendly product. Therefore, it could be an effective product both in the prophylaxis and in the treatment of oral mucositis. However, the small amount of human research is not enough to establish widespread recommendations. Therefore, research in this field should be increased. With this, it will be possible to examine the efficacy and possible complications in the short and long term, explore its possible synergistic effect with other therapies, analyze its economic profitability and the most appropriate type of honey. In this way, healthcare professionals will be able to offer pediatric patients the best care based on the latest scientific evidence.

ABSTRACT

Objective: to evaluate the effect of oral cryotherapy compared to physiological serum on the development of oral mucositis in outpatient cancer patients using the 5-fluorouracil antineoplastic agent. Method: this is a controlled, randomized, double-blind, and multi-center clinical trial, conducted with 60 patients undergoing chemotherapy. The experimental group (n=30) used oral cryotherapy during the infusion of the 5-FU antineoplastic agent, while the control group (n=30) performed mouthwash with physiological serum at their homes. The oral cavity of the participants was assessed at three times: before randomization, and on the 7th and 14th days after using 5-FU. For data analysis, descriptive analyses and the ANOVA, paired t, and McNemar tests were used. Results: there was no statistically significant difference between the experimental and control groups in the assessments regarding the grade of mucositis. However, cryotherapy presented the chance to reduce the presence of intragroup mucositis, between the first and second assessments (p=0.000126). Conclusion: cryotherapy did not obtain statistical significance in relation to oral hygiene with serum, but it proved to be effective intragroup. Record number: RBR-4k7zh3

ABSTRACT

@#Introduction: Erythema multiforme has been known as an infection or drug-associated mucocutaneous eruption characterized by target lesions. A clinical entity, known as Mycoplasma-induced rash and mucositis seen mostly in the pediatric population is emerging and may be associated with atypical pneumonia caused by Mycoplasma pneumoniae. This presents with features overlapping with erythema multiforme and SJS-TEN spectrum but with a different trigger, prognosis, and recurrence rate. Case summary: Target lesions in the clinical setting are usually characteristically associated with erythema multiforme, a mucocutaneous condition associated with an underlying infectious trigger. We present a case of a 10-year-old Filipino boy who was initially diagnosed with erythema multiforme major. Eventual testing for the etiology of the underlying infection, Mycoplasma pneumoniae, proved to be a useful diagnostic that gave a better grasp on the case’s mechanism, sequela, and prognosis. The patient was admitted for pneumonia and his presenting mucositis was severe. Cutaneously, he had atypical target and few target lesions on the trunk and extremities. He was diagnosed as a case of Mycoplasma-induced rash and mucositis (MIRM) and treated with antibiotics and systemic steroids for which he recovered fully in three weeks. MIRM should be separated from erythema multiforme, Stevens Johnsons syndrome and toxic epidermal necrolysis as it follows a different disease course. Conclusion: Mycoplasma-induced rash and mucositis is now considered a distinct entity despite it having overlapping features with erythema multiforme and SJS-TEN spectrum. It presents usually in the younger age group with absent to sparse atypical vesiculobullous or targetoid lesions, significant mucosal involvement, and confluent necrosis on histology. It is important to identify it as a trigger because of its more frequent and severe mucosal sequelae. Management includes symptomatic relief, antibiotic therapy with a macrolide in the presence of pneumonia and systemic steroids when mucositis is severe. Majority of patients achieve full recovery.

ABSTRACT

Abstract Methotrexate is an effective medication to control several diseases; however, it can be very toxic, being myelosuppression one of its main adverse effects, which increases in severity and frequency in patients with renal failure. We present the case of a 68-year-old man with chronic, end-stage renal disease associated with ANCA vasculitis, under treatment with peritoneal dialysis, who received the medication at a low dose, indicated by disease activity, which presented as a complication with severe pancytopenia with mucositis that improved with support measures and multiple-exchange peritoneal dialysis. We reviewed 20 cases published to date of pancytopenia associated with methotrexate in patients on dialysis and found high morbidity and mortality, which is why its use in this type of patient is not recommended. However, when this complication occurs, a therapeutic option could be the use of multiple-exchange peritoneal dialysis in addition to supportive therapy for drug-related toxicity, although it is recognized that studies are required to show the role of multiple-exchange peritoneal dialysis in the removal of this medication.


Resumo Apesar de sua toxicidade, o metotrexato é um medicamento eficaz no controle de várias doenças. A mielossupressão, um de seus principais efeitos adversos, aumenta em gravidade e frequência nos pacientes com insuficiência renal. Apresentamos o caso de um homem de 68 anos de idade com doença renal terminal relacionada à vasculite associada ao ANCA em diálise peritoneal, que recebeu a medicação em dose baixa em função da atividade da doença e que teve como complicação pancitopenia grave com mucosite, tratada com medidas de suporte e diálise peritoneal com múltiplas trocas. Revisamos 20 casos publicados até o presente momento sobre pancitopenia associada a metotrexato em pacientes em diálise. Foi identificada alta morbidade e mortalidade, razão pela qual seu uso nesse tipo de paciente não é recomendado. No entanto, quando esta complicação ocorre, uma opção terapêutica pode ser o uso de diálise peritoneal com múltiplas trocas, além da terapia de suporte para toxicidade medicamentosa. Maiores estudos são necessários para demonstrar o papel da diálise peritoneal com múltiplas trocas na remoção desse medicamento.

ABSTRACT

PURPOSE: This study examined the prevalence and risk factors of peri-implant disease after at least 7 years of dental implant loading.METHODS: A total of 111 patients with 218 dental implants were treated. The follow-up period for all implants was at least 7 years. The patients' dental records were collected and risk factors of peri-implant disease were investigated through logistic regression analysis.RESULTS: The overall implant survival rate was 95.87%, because 9 of the 218 implants failed. The prevalence of peri-implant mucositis and peri-implantitis was 39.7% and 16.7%, respectively. As risk factors, smoking and prosthetic splinting showed significant associations with peri-implantitis (P&0.05).CONCLUSIONS: Within the limits of this study, no significant correlations were found between any risk factors and peri-implant mucositis, but a significantly elevated risk of peri-implantitis was observed in patients who smoked or had splinted prostheses in 2 or more implants.

ABSTRACT

PURPOSE: The purpose of this study was to identify minimum data sets for oral mucous integrity-related documentation and to analyze nursing records for oral care.METHODS: To identify minimum data sets for oral status, the authors reviewed 26 assessment tools and a practical guideline for oral care. The content validity of the minimum data sets was assessed by three nurse specialists. To map the minimum data sets to nursing records, the authors examined 107 nursing records derived from 44 patients who received chemotherapy or hematopoietic stem cell transplantation in one tertiary hospital.RESULTS: The minimum data sets were 10 elements such as location, mucositis grade, pain, hygiene, dysphagia, exudate, inflammation, difficulty speaking, and moisture. Inflammation contained two value sets: type and color. Mucositis grade, pain, dysphagia and inflammation were recorded well, accounting for a complete mapping rate of 100%. Hygiene (100%) was incompletely mapped, and there were no records for exudate (83.2%), difficulty speaking (99.1%), or moisture (88.8%).CONCLUSION: This study found that nursing records on oral mucous integrity were not sufficient and could be improved by adopting minimum data sets as identified in this study.

ABSTRACT

PURPOSE: We conducted a randomized, multicenter, phase III trial to compare S-1 plus docetaxel (DS) with S-1 plus cisplatin (SP) as adjuvant chemotherapy for stage III gastric cancer patients. MATERIALS AND METHODS: Stage III gastric cancer patients who had received curative gastrectomy with D2 lymphadenectomy were randomized into equal groups to receive adjuvant chemotherapy of eight cycles of DS (S-1 70 mg/m2/day on days 1-14 plus docetaxel 35 mg/m2on days 1 and 8) every 3 weeks or SP (S-1 70 mg/m2/day on days 1-14 plus cisplatin 60 mg/m2on day 1) every 3 weeks. The primary endpoint was 3-year disease-free survival (DFS) rate. RESULTS: Between November 2010 and July 2013, 153 patients (75 patients to DS and 78 patients to SP) were enrolled from 8 institutions in Korea. After the capecitabine plus oxaliplatin was approved based on the CLASSIC study, itwas decided to close the study early. With a median follow-up duration of 56.9 months, the 3-year DFS rate between two groups was not significantly different (49.14% in DS group vs. 52.5% in SP group). The most common grade 3-4 adverse event was neutropenia (42.7% in DS and 38.5% in SP, p=0.351). SP group had more grade 3-4 anemia (1.3% vs. 11.5%, p=0.037), whereas grade 3-4 hand-foot syndrome (4.1% vs. 0%, p=0.025) and mucositis (10.7% vs. 2.6%, p=0.001) were more common in DS group. Fifty-one patients (68%) in DS group and 52 (66.7%) in SP group finished planned treatment. CONCLUSION: Our findings suggest that SP or DS is an effective and tolerable option for patients with curatively resected stage III gastric cancer.

ABSTRACT

PURPOSE: We aim to examine nasopharyngeal carcinoma (NPC) characteristics and survival outcomes in patients aged 70 years and older in the intensity-modulated radiotherapy (IMRT) era. MATERIALS AND METHODS: From 2006 to 2013, 126 non-metastatic NPC patients aged ≥ 70 years who were treated with IMRT +/‒ chemotherapy were included. Adult Comorbidity Evaluation 27 (ACE-27) was used to measure patient comorbidities. The overall survival (OS) and cancer-specific survival (CSS)were calculatedwith the Kaplan-Meier method, and differenceswere compared using the log-rank test. The Cox proportional hazards model was used to carry out multivariate analyses. RESULTS: For the entire group, only two patients (1.6%) presented stage I disease, and up to 84.1% patients had stage III-IVB disease. All patients had a comorbidity score of 0 in 24 (19.0%), 1 in 45 (35.7%), 2 in 42 (33.3%), and 3 in 15 (11.9%) patients. The main acute grade during radiotherapy was 3-4 adverse events consisting of mucositis (25.4%), bone marrow suppression (16.7%), and dermatitis (8.7%). After treatment, four patients (3.2%) developed temporal lobe injury. Five-year CSS and OS rates were 67.3% (95% confidence interval [CI], 58.6% to 77.4%) and 54.0% (95% CI, 45.6% to 63.9%), respectively. Five-year OS was significantly higher for ACE-27 score 0-1 than ACE-27 score 2-3 (72.9% and 39.9%, respectively; p 0.05). CONCLUSION: Our findings suggest IMRT +/– chemotherapy has a manageable toxicity and provides an acceptable survival in patients aged ≥ 70 years with NPC. ACE-27 score was significantly associated with survival outcomes in this group population.

ABSTRACT

PURPOSE: Dose-dense chemotherapy (DD-CT) is a preferred (neo)adjuvant regimen in early breast cancer (BC). Although the results of reported randomized trials are conflicting, a recent meta-analysis showed improved overall and disease-free survival with DD-CT compared to conventional schedules. However, no DD-CT safety data for Korean BC patients are available. This phase II study was conducted to evaluate the safety and efficacy of pegteograstim in Korean BC patients receiving DD-CT. MATERIALS AND METHODS: Patients with operable (stage I-III), histologically confirmed BC received four cycles of intravenous doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) on day 1 every 2 weeks as neoadjuvant or adjuvant therapy. Pegteograstim (6.0 mg) was administered subcutaneously on day 2 of each cycle. The primary endpoint was the incidence of febrile neutropenia (FN). The secondary endpoints were safety and tolerability. RESULTS: Of 63 patients, one (1.6%) developed FN during all cycles of DD-CT. Dose delay was observed in four patients (6.3%) and dose reduction in two (3.2%) during DD-CT. Frequent adverse events (AEs) were nausea, alopecia, generalized muscle weakness, myalgia, mucositis, anorexia, dyspepsia, and diarrhea; most AEs were related to chemotherapy. Grade 3-4 AEs were reported in five of 63 patients (7.9%), and all grade 3 and 4 AEs were related to chemotherapy. Adverse drug reactions possibly linked to pegteograstim were abdominal pain, bone pain, myalgia, generalized muscle weakness, and headache in five of 63 patients (7.9%). CONCLUSION: Dose-dense AC (doxorubicin/cyclophosphamide) chemotherapywith pegteograstim support is a tolerable and safe regimen in Korean early BC patients.

ABSTRACT

PURPOSE: The purpose of this study was to retrospectively investigate the survival and success rate of implant-supported fixed prosthesis according to the materials in the posterior area. Other purposes were to observe the complications and evaluate the factors affecting failure. MATERIALS AND METHODS: Patients who had been restored implant prosthesis in the posterior area by the same prosthodontist in the department of prosthodontics, dental hospital, Chonbuk National University, in the period from January 2011 to June 2018 were selected for the study. The patient's sex, age, material, location, type of prosthesis and complications were examined using medical records. The Kaplan-Meier method was used to analyze the survival and success rate. The Log-rank test was conducted to compare the differences between the groups. Cox proportional hazards model was used to assess the association between potential risk factors and success rate. RESULTS: A total of 364 implants were observed in 245 patients, with an average follow-up of 17.1 months. A total of 5 implant prostheses failed and were removed, and the 3 and 5 year cumulative survival rate of all implant prostheses were 97.5 and 91.0, respectively. The 3 and 5 year cumulative success rate of all implant prostheses were 61.1% and 32.9%, respectively. Material, sex, age, location and type of prosthesis did not affect success rate (P>.05). Complications occurred in the order of proximal contact loss (53 cases), retention loss (17 cases), peri-implant mucositis (12 cases), infraocclusion (4 cases) and so on. CONCLUSION: Considering a high cumulative survival rate of implant-supported fixed prostheses, regardless of the materials, implant restored in posterior area can be considered as a reliable treatment to tooth replacement. However, regular inspections and, if necessary, repairs and adjustments are very important because of the frequent occurrence of complications

ABSTRACT

Purpose: We investigated the clinical outcome of sodium alginate treatment in radiation-induced pharyngeal mucositis (RIPM) after neck irradiation. Materials and methods: The study population included 32 patients (11 lung cancer, 10 breast cancer, 7 head and neck cancer, and 4 other primary lesions) who underwent neck external beam radiotherapy at the authors' institution between June 2006 and 2016. The patients received 5% sodium alginate solution orally for RIPM. Those who were followed up for less than 2 months or did not receive 5% sodium alginate were excluded from this retrospective study. RIPM was graded weekly as an acute toxicity according to the Common Terminology Criteria for Adverse Events (CTCAE), version 4. The administration of 10-15 ml of sodium alginate before each meal was continued until the radiotherapy was completed and after resolution of odynophagia. The efficacy of sodium alginate was assessed by two radiation oncologists as follows: Grade I, ineffective; grade II, moderately effective; grade III, very effective. When sodium alginate was ineffective, other analgesics, such as nonsteroidal antiinflammatory drugs (NSAIDS) or opioids, were added. Relationships between the presence/absence of additional analgesics and the radiation dose were investigated. Results: The median duration from the start of irradiation to sodium alginate administration was 15 days (range, 5­36 days). RIPM improved in 29/32 patients (grade: II, n = 22; III, n = 7). Three patients showed no improvement. No sodium alginate-related toxicities occurred. Additional analgesics were required in 5/32 patients. The radiation dose in these 5 patients was significantly higher than that in the sodium alginate-alone group (63.6 ± 7.8 Gy vs 48.3 ± 14.8Gy, P = 0.02). Patients who received > 50 Gy tended to require additional analgesics more frequently than those who received ≤50Gy (P = 0.10). Conclusions: The concurrent administration of sodium alginate and neck irradiation was feasible and tolerable without obvious toxicities. Under certain conditions sodium alginate could be a promising alternative to NSAIDs and opioids in RIPM. The results justify further prospective evaluations with detailed treatment protocols to clarify whether sodium alginate can improve RIPM (AU)

ABSTRACT

Atualmente, a busca por saúde permeia desde o bem estar físico até conceitos estéticos, para se alcançar os parâmetros pessoais de cada indivíduo. Para um correto planejamento reabilitador, devemos considerar várias possibilidades para evitar falhas funcionais e estéticas. Dentre as falhas tardias observamos as doenças peri-implantares, como por exemplo a Mucosite Peri-implatar e a Peri-implantite. Considerando a complexidade e importância da compreensão das doenças Peri implantares, este trabalho tem como objetivo, através de uma revisão da literatura, discutir os aspectos inerentes à etiologia, diagnóstico e classificação das doenças peri-implantares. O tecido peri-implantar e o tecido periodontal possuem estruturas anatômicas similares, mas possuem diferenças estruturais também. Estes fatos também determinam semelhanças e diferenças nas doenças periodontais e peri-implantares. Sabe-se que o principal fator etiológico das doenças periodontais é o biofilme bacteriano, e nas doenças peri-implantares este também é o principal fator etiológico. O mesmo padrão prevalece para alguns fatores etiológicos secundários ou modificadores. Várias são as propostas de classificação das doenças e condições peri-implantares baseadas na gravidade dos comprometimentos clínicos, nos fatores etiológicos, na associação com outras enfermidades e até com fatores iatrogênicos determinantes. Mas nenhuma contempla estes fatores etiológicos juntos e sabe-se que um correto diagnóstico é determinante para um bom plano de tratamento e determinação de sucesso e longevidade das reabilitações peri-implantares (AU)


Currently, the pursuit for health permeates from the physical well-being to aesthetic concepts, in order to achievethe personal parameters of each individual. For a correct rehabilitation planning we must consider several possibilities to avoid functional and aesthetic failures. Among late failures, there are peri-implant diseases, such as Periimplantar Mucositis and Peri-implantitis. Considering the complexity and importance of the understanding of periimplant diseases, this paper aims, through a literature review, to discuss the inherent aspects of the etiology, diagnosis and classification of these peri-implant diseases. Although they have similar anatomical structure, periodontal and peri-impant tissues have some structural diferences. These facts determine similarities and diferences between periodontal and periimplant diseases. It is known that the main etiological factor of periodontal diseases is bacterial biofilm, and in peri-implant diseases this is also the main etiological factor. The same pattern prevails for some secondary or modifiers etiological factors. There are several suggestions for the classification of peri-implant conditions and diseases based on theseverity of clinical complications, etiological factors, association with other diseases and even iatrogenic factors. But none considers these factors together and it is knownthat a correct diagnosis is determinant for a good treatment plan and determination of success and longevity of the peri-implant rehabilitations (AU)

ABSTRACT

BACKGROUND: Oral mucositis during radiotherapy which is harmful to the patients with head and neck is suggested to be related to the oral hygiene and health. Therefore, we evaluated the oral health status in relation to the occurrence of mucositis among patients with head and neck cancer during radiotherapy. METHODS: Tooth plaque index (PI), periodontal depth, and oral mucositis in 50 patients with head and neck cancer were examined by a dentist for 8 weeks after radiotherapy initiation. Cancer type and site were recorded based on the patients’ medical records. In addition, we assessed oral health-related quality of life. RESULTS: The mean age of participants was 56.3 ± 11.6 years, with patients aged > 60 years comprising the largest proportion of the mucositis group. The median (range) of the PI index were 0 (0–3) and 1 (0–3) among participants with mucositis and those without, respectively, with no significant difference (P = 0.761). The median (range) of the total Oral Health Impact Profile score were 54 (42–58) and 41 (14–70) among participants without mucositis and those with mucositis, respectively (P = 0.037). CONCLUSIONS: This study showed that patients who developed mucositis during radiotherapy had lower oral health-related quality of life than those who did not. However, there was no difference in oral health status according to mucositis.

ABSTRACT

PURPOSE: The purpose of this study was to examine the effects of oral cryotherapy on oral mucositis, reactive oxygen series, inflammatory cytokines, and oral comfort in patients undergoing chemotherapy for gynecologic cancers. METHODS: Participants were randomly assigned to the experimental group (n=25, receiving oral cryotherapy during chemotherapy) and the control group (n=25, receiving the usual care consisting of 0.9% normal saline gargles three times before meals). Oral mucositis was assessed using the oral assessment guide, while oral comfort was assessed using the oral perception guide. Reactive oxygen series was measured as total oxidant stress, and the level of two inflammatory markers, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), were examined. The data were analyzed using t-test, chi-square test, Fisher's exact test, Mann-Whitney U-test, and repeated measures analysis of variance. RESULTS: There was a significant difference in the oral mucositis score, reactive oxygen series score, TNF-α level, and oral comfort score between the two groups, and there were significant changes over time and in the group-by-time interactions. There was a significant difference in the IL-6 score between the two groups, but there were no significant changes over time or in the group-by-time interactions. CONCLUSION: The study results revealed that oral cryotherapy was more effective than the usual care regime of normal saline gargles for reducing oral mucositis, reactive oxygen series, and inflammatory cytokines and for improving oral comfort in gynecologic cancer patients undergoing chemotherapy.

ABSTRACT

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) patients need parenteral nutrition because of nausea, vomiting, and mucositis caused by conditioning regimens. The demand for glutamine increases during the HSCT period. We evaluated the effects of glutamine-containing parenteral nutrition on the clinical outcomes of HSCT patients. METHODS: In this retrospective analysis, we reviewed HSCT patients from Seoul National University from August 2013 to July 2017. Depending on their glutamine supplementation status, 91 patients were divided into 2 groups: glutamine group (N=44) and non-glutamine group (N=47). We analyzed the rate of weight change, infection (clinically/microbiologically documented), complications (duration of mucositis and neutropenia, acute graft versus host disease), and 100-days mortality in each group. RESULTS: Regarding the clinical characteristics of the patients, there were no significant differences between the 2 groups except that there was a larger proportion of myeloablative conditioning regimen in the glutamine group (P=0.005). In the glutamine group, the average number of days of glutamine use, parenteral nutrition, and mucositis was 7.6±1.4, 14.6±9.9, and 13.3±9.5, respectively. Furthermore, multivariate analysis revealed odds ratios of 0.37 (95% CI, 0.14–0.96; P=0.042) and 0.08 (95% CI, 0.01–0.98; P=0.048) for clinically documented infection and 100-days mortality, respectively, in the glutamine group. CONCLUSION: Results showed that the glutamine group had less clinically documented infection and 100-days mortality than the non-glutamine group, but the other outcomes did not show significant differences. The extended duration of glutamine supplementation according to the period of total parenteral nutrition and mucositis should be considered.
