Plasma Cell Mucositis: A Clinical Conundrum.

Plasma cell mucositis (PCM) is an unusual disorder most evident in the accessible mucosa and usually reported in the upper aerodigestive tract, although it is named according to its specific anatomical site of involvement such as plasma cell cheilitis, plasma cell gingivitis, plasma cell vulvitis, and Zoon's balanitis. PCM reflects a dense polyclonal rather than a monoclonal plasma cell proliferation of unclear and unknown etiology. This perplexing disorder tends to be treated by avoiding possible triggers and intralesional and/or systemic steroids. In this work, we provide a review and update on PCM, which often represents a clinical conundrum.

Diagnostic potential of endothelin-1 in peri-implant diseases: a cross-sectional study.

PURPOSE: This study aimed to evaluate the potential of Endothelin-1 (ET-1), a peptide derived from vascular endothelial cells, as a biomarker for diagnosing peri-implant diseases. METHODS: A cohort of 29 patients with a total of 76 implants was included in this study and subsequently divided into three groups based on peri-implant clinical parameters and radiographic examination: healthy (peri-implant health) (n = 29), mucositis (n = 22), and peri-implantitis (n = 25) groups. The levels of ET-1 (ρg/site) and interleukin (IL)-1ß (ρg/site) in peri-implant sulcus fluid (PISF) samples were determined using enzyme immunoassay. Statistical analyses were conducted using Kruskal-Wallis and Steel-Dwass tests. Logistic regression and receiver operating characteristic (ROC) curve analyses were performed to evaluate the diagnostic performance of the biomarkers. RESULTS: ET-1 levels were significantly elevated in the peri-implantitis group compared to those in the healthy group, and were highest in the peri-implant mucositis group. Additionally, IL-1ß levels were significantly higher in the peri-implantitis group than those in the healthy group. ROC curve analysis indicated that ET-1 exhibited superior area under the curve values, sensitivity, and specificity compared to those of IL-1ß. CONCLUSIONS: Our findings suggest that the presence of ET-1 in PISF plays a role in peri-implant diseases. Its significantly increased expression in peri-implant mucositis indicates its potential for enabling earlier and more accurate assessments of peri-implant inflammation when combined with conventional examination methods.

Peri-implant mucositis and peri-implantitis: key features and differences.

Peri-implant diseases are frequent complications that occur around osseointegrated endosseous implants and are the result of an imbalance between the bacterial challenge and host response. Peri-implant diseases may affect the peri-implant mucosa only (peri-implant mucositis) or also involve the supporting bone (peri-implantitis). Early detection of peri-implant diseases and timely treatment is important for the success of dental implant treatment. Peri-implant probing is essential to assess the peri-implant health status and should be done at each recall visit. Dental practitioners should be familiar with the clinical and radiological features of both conditions in order to make an accurate diagnosis and determine the appropriate treatment required. This article aims to provide clinicians with an understanding of the key differences between peri-implant health, peri-implant mucositis and peri-implantitis.

Methotrexate-induced Severe Pancytopenia in a Patient with Rheumatoid Arthritis: A Case Report and Review of Literature.

Toxicity associated with low doses of methotrexate (MTX) is low, but it may be fatal. Bone marrow suppression and mucositis are among the common side effects of low dose MTX toxicity. Different risk factors have been reported for toxicities associated with low doses of MTX, including accidental use of higher doses, renal dysfunction, hypoalbuminemia, and polypharmacy. In this paper, we present a female patient who had mistakenly used 7.5 mg of MTX daily instead of the same dose of MTX on Thursday and Friday. She was presented with mucositis and diarrhea to the emergency department. Moreover, we searched the databases Scopus and PubMed for available studies and case reports on toxicities associated with MTX dosing errors. The most frequently observed toxicities included gastrointestinal lesions, nausea, vomiting, skin lesions, and bone marrow suppression. Leucovorin, hydration, and urine alkalinization were among the most frequently used treatments. Finally, we summarize the data on the toxicities of low doses of MTX in different diseases.

Reliability assessment of the 2018 classification case definitions of peri-implant health, peri-implant mucositis, and peri-implantitis.

BACKGROUND: The purpose of this study was to evaluate the reliability and accuracy in the assignment of the case definitions of peri-implant health and diseases according to the 2018 Classification of Periodontal and Peri-implant Diseases and Conditions. METHODS: Ten undergraduate students, 10 general dentists, and 10 experts in implant dentistry participated in this study. All examiners were provided with clinical and radiographic documentation of 25 dental implants. Eleven out the 25 cases were also accompanied by baseline readings. Examiners were asked to define all cases using the 2018 classification case definitions. Reliability among examiners was evaluated using the Fleiss kappa statistic. Accuracy was estimated using percentage of complete agreement and quadratic weighted kappa for pairwise comparisons between each rater and a gold standard diagnosis. RESULTS: The Fleiss kappa was 0.50 (95% CI: 0.48 to 0.51) and the mean quadratic weighted kappa value was 0.544. Complete agreement with the gold standard diagnosis was achieved in 59.8% of the cases. Expertise in implantology affected accuracy positively (p < 0.001) while the absence of baseline readings affected it negatively (p < 0.001). CONCLUSION: Both reliability and accuracy in assigning case definitions to dental implants according to the 2018 classification were mostly moderate. Some difficulties arose in the presence of specific challenging scenarios.

Ocular involvement in Mycoplasma induced rash and mucositis: A systematic review of the literature.

Mycoplasma pneumoniae induced rash and mucositis (MIRM) is a relatively newly identified clinical entity which is characterized by mucocutaneous manifestations in the setting of Mycoplasma infection. Though a clinically distinct disease, MIRM exists on a diagnostic continuum with entities including erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and the recently described reactive infectious mucocutaneous eruption (RIME). In this systematic review, we discuss published findings on the epidemiology, clinical manifestations, diagnosis, and management of MIRM, with an emphasis on ocular disease. Lastly, we discuss some of the most recent developments and challenges in characterizing MIRM with respect to the related diagnosis of RIME.

Clinical Updates in Mucositis-Related Symptom Management.

OBJECTIVE: To provide an overview with the most up-to-date evidence on the management of cancer-treatment related mucositis. DATA SOURCES: Peer-reviewed articles, textbooks, and the internet. CONCLUSION: A multitude of new and innovative treatments for the management of mucositis exist. Mucositis guidelines have changed to reflect the current evidence, but more research is needed on emerging modalities. IMPLICATIONS FOR NURSING PRACTICE: Oncology nurses have a primary role in the assessment and early identification of mucositis. Educating patients and recommending evidence-based guidelines is paramount in preventing and ameliorating this challenging side effect of treatment.

Mycoplasma pneumoniae-induced rash and mucositis: A new entity.

Mycoplasma pneumoniae is a well-known cause of community-acquired pneumonia, mostly associated with dermatological manifestations especially with mucosal involvement and targetoid cutaneous lesions. For many years, it was considered among the spectrum of erythema multiforme. Recently, some authors have recommended the creation of a new syndrome called "mycoplasma-induced rash and mucositis." This new syndrome has distinct epidemiological, clinical and histological features making it different from drug-induced Stevens-Johnson syndrome, toxic epidermal necrosis and erythema multiforme. Herein, we report two patients with acute Mycoplasma pneumoniae respiratory tract infection presenting severe mucocutaneous lesions in accordance with this new syndrome.

Mucosal Respiratory Syndrome: A Systematic Literature Review.

BACKGROUND: Mycoplasma pneumoniae atypical pneumonia is frequently associated with erythema multiforme. Occasionally, a mycoplasma infection does not trigger any cutaneous but exclusively mucosal lesions. The term mucosal respiratory syndrome is employed to denote the latter condition. Available reviews do not address the possible association of mucosal respiratory syndrome with further atypical bacterial pathogens such as Chlamydophila pneumoniae, Chlamydophila psittaci, Coxiella burnetii, Francisella tularensis, or Legionella species. We therefore performed a systematic review of the literature addressing this issue in the National Library of Medicine, Excerpta Medica, and Web of Science databases. SUMMARY: We found 63 patients (≤18 years, n = 36; >18 years, n = 27; 54 males and 9 females) affected by a mucosal respiratory syndrome. Fifty-three cases were temporally associated with a M. pneumoniae and 5 with a C. pneumoniae infection. No cases temporally associated with C. psittaci, C. burnetii, F. tularensis, or Legionella species infection were found. Two cases were temporally associated with Epstein-Barr virus or influenzavirus B, respectively.

Validity and reliability of the Persian version of the oropharyngeal Mucositis quality of life scale.

BACKGROUND: Oral mucositis is one of the serious complications of chemotherapy and/or radiotherapy that significantly affects the quality of patients' life. The Oropharyngeal Mucositis-Specific Quality-of-Life questionnaire (OMQoL) is an acceptable instrument for measuring the quality of life in these patients. The aim of this study was to evaluate the validity and reliability of the Persian version of OMQoL questionnaire. METHODS: This study was a cross-sectional and multi-centric research. After translation from English to Persian, back translation, and cultural adaptation, the Persian version of the questionnaire was prepared. One hundred forty-four patients suffering from oral mucositis referred to three different university affiliated hospitals related to Zahedan, Kerman and Tehran Universities of Medical Sciences, were participated in this study. Then the questionnaire was completed by trained interviewers. The reliability was assessed by Cronbach's alpha coefficient, and validity was measured through factor analysis, and construct validity (including discriminant validity, and convergent validity) methods. RESULTS: Cronbach's alpha in all dimensions was higher than 0.9 that indicated a perfect internal consistency. The results of factor analysis indicated that the dimensions specified in the Persian version were the same as the original version (Factor loading of all items > 0.4). The correlation coefficient for all items was more than 0.75, and the convergence validity was 100% in all dimensions. CONCLUSION: The results of this study showed that the reliability, and validity of Persian version of OMQoL were acceptable, which can be used to measure the quality of life in patients with oral mucositis.

Mucositis periimplantaria asociada a ortodoncia correctiva / Peri-implant mucositis associated to corrective orthodontics

Introducción: Los minitornillos de ortodoncia son dispositivos temporales de anclaje utilizados ampliamente en ortodoncia correctiva. Sin embargo, se ha reportado en la literatura que su tasa clínica de éxito no es completa debido a que pueden existir fallas relacionadas con la pérdida de su estabilidad. Varios factores pueden comprometer el anclaje y están relacionados con el tipo de implante, su manejo quirúrgico y el hospedero. Dentro de este último, se encuentra la inflamación del tejido periimplantario o mucositis que, aunque reversible, es necesario su tratamiento temprano para evitar su progresión a la afectación de tejido duro (periimplantitis). Objetivo: Describir un caso clínico de mucositis periimplantaria asociada a un dispositivo de anclaje ortodóntico temporal. Presentación del caso: Paciente femenina que acudió a la consulta por presentar dolor en la zona anterior del maxilar superior. Durante el examen intraoral se observó que usaba aparatos de ortodoncia con mecanismo de anclaje: dos minitornillos de ortodoncia ubicados al nivel de los caninos superiores. Se realizó la remoción quirúrgica de los minitornillos de ortodoncia, se le indicó el uso de antibióticos y se realizó estudio histopatológico para descartar malignidad. Se diagnosticó con mucositis periimplantaria. Conclusiones: La remoción quirúrgica de los minitornillos de ortodoncia es una excelente alternativa para evitar la progresión de la lesión hacia los tejidos duros. A través de esta técnica lograron eliminar signos de dolor, enrojecimiento y sangrado(AU)

Introduction: Orthodontic miniscrews are temporary anchorage devices widely used in corrective orthodontics. However, it has been reported in the literature that their clinical success rate is not high, due to failures related to the loss of stability. Anchorage may be affected by factors associated to the type of implant, its surgical management and the host. Host-related factors include peri-implant tissue inflammation or mucositis, which though reversible, its early treatment is necessary to prevent expansion into and damage to the hard tissue (peri-implantitis). Objective: Describe a clinical case of peri-implant mucositis associated to a temporary orthodontic anchorage device. Case presentation: A female patient attends clinical consultation with pain in the anterior zone of her upper maxilla. Intraoral examination revealed the presence of orthodontic appliances with an anchorage mechanism: two orthodontic miniscrews located at the level of the upper canines. Surgical removal was performed of the orthodontic miniscrews, antibiotics were indicated and histopathological testing was conducted to rule out malignancy. The patient was diagnosed with peri-implant mucositis. Conclusions: Surgical removal of orthodontic miniscrews is an excellent alternative to prevent the progress of the lesion into hard tissues. Pain signs, reddening and bleeding were all eliminated with the technique applied(AU)

A pilot study of the effect of a home-based multimodal symptom-management program in children and adolescents undergoing chemotherapy.

BACKGROUND: Prevalent symptoms that affect children and adolescents throughout the process of cancer diagnosis and treatment include nausea and vomiting, fatigue, pain, mucositis, and anxiety. AIM: To examine the effect of a home-based multimodal symptom-management program for alleviation of nausea and vomiting, fatigue, pain, mucositis, and anxiety in children and adolescents undergoing chemotherapy for hematological malignancies or solid tumors. METHODS: In an exploratory pilot randomized study with qualitative interview, patients between 10 and 18 years of age were randomly assigned to either the symptom-management program plus usual care (intervention group) or usual care (control group). The program consisted of multiple nonpharmacological interventional components. The targeted symptoms were measured at baseline (after diagnosis), at the first 2 weeks of each cycle of chemotherapy, and at 6 months after baseline, using the Memorial Symptom Assessment Scale 10-18 and the State Anxiety Scale for Children. RESULTS: Fifty children (31 boys; mean age, 13.7 years) were randomized either to the intervention group or the control group (25 each) and underwent baseline assessment. A comparison between the groups showed that the intervention group had a significant less fatigue over time (P < .05). However, no differences were found with respect to nausea and vomiting, pain, mucositis, and anxiety between groups. Both children and parents reported a positive experience with the symptom-management program. CONCLUSION: The home-based symptom-management program may have helped to reduce fatigue in children and adolescents undergoing chemotherapy. In addition, qualitative data support the importance of improving children and parents' knowledge, coping skills, and psychological preparation for symptoms associated with chemotherapy.

Mycoplasma-Induced Rash and Mucositis or Steven-Johnson Syndrome.

Mycoplasma-induced rash and mucositis (MIRM), has been recently distinguished as an entity distinct from the spectrum of Steven-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). It is characterized by a younger age of onset, predominant mucosal lesions and sparse skin involvement, in contrast to widespread cutaneous lesions in TEN/SJS. While therapy with azithromycin and a short course of corticosteroids suffices in the majority of cases, intravenous immunoglobulin and cyclosporine may be useful in refractory cases. The authors report a 6-y-old girl with mucopurulent conjunctivitis, hemorrhagic oral mucosal crusting, maculopapular skin rash, and positive serology for Mycoplasma pneumoniae. The girl recovered following therapy with azithromycin and oral prednisolone. The index case is instructive in highlighting a rare complication of a common infection, and delineates the importance of clinical suspicion and a systematic approach to evaluation and management of MIRM in patients with unusual mucosal lesions and skin rash.

Adenoviral-induced rash and mucositis: Expanding the spectrum of reactive infectious mucocutaneous eruption.

Mucocutaneous eruptions associated with respiratory pathogens, specifically Mycoplasma pneumoniae (MP), has recently been described as a MIRM (MP-induced rash and mucositis). The term reactive infectious mucocutaneous eruption (RIME) has been proposed, since non-MP pathogens may also cause a similar rash and mucositis. We report two cases with clinical manifestations suggestive of MIRM/RIME, both with documented adenovirus infection.
