BACKGROUND
Current treatment for head and neck cancers (HNCs) have led to an improved survival. However, the sequelae of cancer treatment often result in trismus, or reduced mouth opening. The purpose of this report is to identify interventional studies for trismus management in HNC patients.
METHODS
A search of PubMed, Embase, Cumulated Index to Nursing and Allied Health Literature, and the Cochrane Library was conducted in March 2020 for randomized controlled trials (RCTs) involving interventions for trismus for head and neck cancer within 10 years. Intervention could involve the use of an exercise regime, jaw rehabilitation device, technological device, medication or massage therapy. The primary outcome was the measurement of mouth opening.
RESULTS
Eleven RCTs involving a total of 685 patients with HNC were included. Six RCTs evaluated the effectiveness of a jaw mobilization device with exercises; there was no significant benefit of an exercise regime with a jaw mobilization device either initiated before, during or after treatment compared to no exercise. Two RCTs compared 2 intervention groups that involved exercises only, with 1 study assessing the benefit of weekly supervised physical therapy with gum chewing and another evaluating the benefit of immediate (1-2 days) versus delayed (7-10 days) initiation of exercise post-surgery; there was no significant difference between groups in either study. One RCT that recruited only patients with trismus demonstrated that an exercise regime in combination with low-level laser therapy or low-intensity ultrasound had superior results in mouth opening measurements compared to exercise alone. Two RCTs compared intervention groups with and without follow-up reminders; both studies showed a significant improvement in mouth opening measurements in groups with follow-up reminders.
CONCLUSION
This systematic review did not convey a clear consensus as to optimal intervention for trismus in HNC patients. A variety of exercise regimens and jaw rehabilitation devices appear to have comparable effectiveness. However, efforts focused on increasing adherence to a particular intervention protocol may positively impact mouth opening measures in head and neck cancer patients. Also, low-level laser therapy and low-intensity ultrasound coupled with exercise may be beneficial for patients with trismus.

Review
A systematic review of metastatic cancer presenting in osteonecrosis of the jaws (MC-ONJ) in patients undergoing antiresorptive and/or antiangiogenic therapy for skeletal-related adverse events.
INTRODUCTION
Osteonecrosis of the jaw (ONJ) is reported to be primarily associated with patients receiving bisphosphonate therapies but has been found in patients taking a number of other medications. A number of recent reports have noted the presence of metastatic cancers in the histologic analysis of osteonecrotic lesions from the jaw. The aim of the present review is to estimate the frequency and the type of metastatic cancer most commonly found in ONJ specimens in patients undergoing antiresorptive and/or antiangiogenic drug therapy.
MATERIAL AND METHODS
A multidatabase (PubMed, MEDLINE, EMBASE, and CINAHL) systematic search was performed. Any studies involving human participants treated with antiresorptive and antiangiogenic drugs were considered. Where study patients presented with malignant cells within osteonecrotic specimens, further data were collected. Data are presented using descriptive statistics.
RESULTS
A total of 13 studies met the inclusion criteria for this systematic review. Thirty-seven study patients had histologic evidence of malignant cells within medication-related osteonecrosis of the jaw (MRONJ) specimens. The most frequent phenotype of malignant cells found within MRONJ specimens were breast cancer variants (n = 15). The frequency of malignant tumor cells found within the MRONJ specimens was calculated using 4 studies. Out of 604 patients, the frequency was 4.64% (n = 28).
CONCLUSIONS
Based on the limited data available in the literature, it is plausible that not histologically analyzing all ONJ specimens could result in a small number of undiagnosed and untreated malignant diseases. Additional data based on a larger cohort of study patients is necessary to understand the role of MRONJ in metastatic spread and the influence of surgical treatment and reoccurrence.

BACKGROUND
Metastases in the oral cavity are rare and account for only 1 to 3% of all malignant lesions in this area. The primary location from which most metastases have been described in the oral cavity in adult patients include lungs, breasts, kidneys and colon.
MATERIAL AND METHODS
A systematic search of the literature was carried out following the PRISMA statement in PubMed database. Clinical trials and case series published in the last 10 years [2010-2020] were eligible to be selected. The headings and keywords used in the searches were "cancer" AND "oral metastases", "incidence" AND "oral metastases", "oral metastases" AND "jaw bone", "oral metastases" AND "soft tissue".
RESULTS
For the study of the incidence of metastases in the oral cavity, 9 reports of clinical trials and 7 retrospective studies of case series have been included in this article. The primary locations from which more metastases have been described in the oral cavity are lungs (30.6% or 183 cases), breasts (22.2% or 133 cases), liver (15.5% or 93 cases), prostate (9 % or 54 cases), thyroid glands (8.1% or 49 cases), kidneys (7.3% or 44 cases), skin (2.3% or 14 cases), soft tissues (2% or 12 cases), colon (2% or 12 cases) and gastrointestinal (0.6% or 4 cases). These metastases have a predilection for hard tissues. The clinical presentation of these lesions varies from painless granulomatous lesions to lytic areas in the jaws.
CONCLUSIONS
Although metastases in the oral cavity is an uncommon pathology, early diagnosis is needed so that in the event that it is the first manifestation, it allows the primary tumor to be diagnosed as soon as possible.

Rosai-Dorfman disease (RDD) is a benign, self-limiting histiocytosis of unknown etiology. The classic form of the condition includes a painless cervical lymphaenopathy accompanied by fever, weight loss and an elevated ESR. Extra nodal RDD (ENRDD) is most frequent in the head and neck. Thirty-eight cases of ENRDD have been described. Seven cases of ENRDD were identified in our pathology biopsy services. The demographic and clinical information was tabulated logically on the basis of age, gender, location and presence or absence of symptoms, treatment and follow-up. Radiographic and histopathological features were also examined. The findings in these cases were correlated with those available from the previously reported cases. Six cases affected women and one case was diagnosed in a male. The age ranged from 22-55 years. Three cases presented as a nasal mass. One of these lesions extended into the paranasal sinuses. One case was located in the maxilla and extended to involve the maxillary sinus. Three cases were diagnosed in the mandible. The maxillary and one mandibular lesion (Case 2) resulted in significant painful irregular bone destruction with a non-healing socket and tooth mobility respectively. One mandibular lesion was asymptomatic (Case 6). The third case affecting the mandible presented as a rapidly expansile mass following a tooth extraction (Case 7). Nasal masses presented with symptoms of obstruction. Nasal masses were excised with no recurrence from up to 2-3 years of follow-up. The mandibular lesions were curetted aggressively. The oral mass in Case 7 was excised synchronously. No recurrence up to 2 years was recorded in Case 2. Follow-up information is not available for Cases 6 and 7. The maxillary lesion was not intervened surgically. The patient has persistent but stable disease for a follow-up period of 2 years. ENRDD is rarely considered in the differential diagnosis in the absence of lymph node involvement. Lesions of ENRDD resemble many other histiocytic and histiocyte-rich lesions of the head and neck. This makes the diagnosis of ENRDD challenging with the potential for under diagnosis or misdiagnosis and delay in treatment.

Meta-Analysis
PURPOSE
The aim was to identify whether malignant diseases increase the risk of medication-related osteonecrosis of the jaw (MRONJ) occurrence when patients are exposed to bisphosphonate, antiresorptive or antiangiogenic drugs. To analyze related factors.
METHODS
A systematic literature searching was performed in PubMed, Embase, and Google Scholar for studies with information about whether patients have malignant diseases. Patients involved must be treated with MRONJ-related drugs and at high risk of developing MRONJ.
RESULTS
A total of 6 cohort studies and 3 case-control studies were included. Analysis according 9 studies shows that malignant diseases have significant influence on MRONJ occurrence (risk ratio (RR): 2.62; 95% confidence interval (95% CI): 1.58-4.33; P =0.0002). Subgroup analysis according 6 cohort studies also shows that malignant diseases significantly affect MRONJ occurrence (RR: 3.50; 95% CI: 1.63-7.52; P =0.001). Chemotherapy have no obvious influence on MRONJ occurrence (RR: 1.64; 95% CI: 0.79-3.39; P =0.18). Intravenous drug administration significantly influences MRONJ occurrence (RR: 2.67; 95% CI: 1.27-5.58; P =0.009).
CONCLUSIONS
Patients with malignant diseases have higher risk of MRONJ occurrence when exposed to bisphosphonate, antiresorptive, or antiangiogenic drugs. Cumulative dosages from intravenous drugs administration contribute to MRONJ developing. Prevention of MRONJ in patients with malignancy should be emphasized.

Meta-Analysis
BACKGROUND
Bisphosphonate drugs can be used to improve the outcomes of women with breast cancer. Whilst many meta-analyses have quantified their potential benefits for patients, attempts at comprehensive quantification of potential adverse effects have been limited. We undertook a meta-analysis with novel methodology to identify and quantify these adverse effects.
METHODS
We systematically reviewed randomised controlled trials in breast cancer where at least one of the treatments was a bisphosphonate (zoledronic acid, ibandronate, pamidronate, alendronate or clodronate). Neoadjuvant, adjuvant and metastatic settings were examined. Primary outcomes were adverse events of any type or severity (excluding death). We carried out pairwise and network meta-analyses to estimate the size of any adverse effects potentially related to bisphosphonates. In order to ascertain whether adverse effects differed by individual factors such as age, or interacted with other common adjuvant breast cancer treatments, we examined individual-level patient data for one large trial, AZURE.
FINDINGS
We identified 56 trials that reported adverse data, which included a total of 29,248 patients (18,301 receiving bisphosphonate drugs versus 10,947 not). 24 out of the 103 different adverse outcomes analysed showed a statistically and practically significant increase in patients receiving a bisphosphonate drug compared with those not (2 additional outcomes that appeared statistically significant came only from small studies with low event counts and no clinical suspicion so are likely artifacts). Most of these 24 are already clinically recognised: 'flu-like symptoms, fever, headache and chills; increased bone pain, arthralgia, myalgia, back pain; cardiac events, thromboembolic events; hypocalcaemia and osteonecrosis of the jaw; as well as possibly stiffness and nausea. Oral clodronate appeared to increase the risk of vomiting and diarrhoea (which may also be increased by other bisphosphonates), and there may be some hepatotoxicity. Four additional potential adverse effects emerged for bisphosphonate drugs in this analysis which have not classically be recognised: fatigue, neurosensory problems, hypertonia/muscle spasms and possibly dysgeusia. Several symptoms previously reported as potential side effects in the literature were not significantly increased in this analysis: constipation, insomnia, respiratory problems, oedema or thirst/dry mouth. Individual patient-level data and subgroup analysis revealed little variation in side effects between women of different ages or menopausal status, those with metastatic versus non-metastatic cancer, or between women receiving different concurrent breast cancer therapies.
CONCLUSIONS
This meta-analysis has produced estimates for the absolute frequencies of a range of side effects significantly associated with bisphosphonate drugs when used by breast cancer patients. These results show good agreement with previous literature on the subject but are the first systematic quantification of side effects and their severities. However, the analysis is limited by the availability and quality of data on adverse events, and the potential for bias introduced by a lack of standards for reporting of such events. We therefore present a table of adverse effects for bisphosphonates, identified and quantified to the best of our ability from a large number of trials, which we hope can be used to improve the communication of the potential harms of these drugs to patients and their healthcare providers.

BACKGROUND
Three-dimensional (3D) printing is now a widely recognized surgical tool in oral and maxillofacial surgery. However, little is known about its benefits for the surgical management of benign maxillary and mandibular tumors and cysts.
PURPOSE
The objective of this systematic review was to assess the contribution of 3D printing in the management of benign jaw lesions.
METHODS
A systematic review, registered in PROSPERO, was conducted using PubMed and Scopus databases, up to December 2022, by following PRISMA guidelines. Studies reporting 3D printing applications for the surgical management of benign jaw lesions were considered.
RESULTS
This review included thirteen studies involving 74 patients. The principal use of 3D printing was to produce anatomical models, intraoperative surgical guides, or both, allowing for the successful removal of maxillary and mandibular lesions. The greatest reported benefits of printed models were the visualization of the lesion and its anatomical relationships to anticipate intraoperative risks. Surgical guides were designed as drilling locating guides or osteotomy cutting guides and contributed to decreasing operating time and improving the accuracy of the surgery.
CONCLUSION
Using 3D printing technologies to manage benign jaw lesions results in less invasive procedures by facilitating precise osteotomies, reducing operating times, and complications. More studies with higher levels of evidence are needed to confirm our results.

BACKGROUND
Osteoradionecrosis of the jaws (ORNJ) is a severe and challenging complication of head and neck radiation therapy. Despite its aggressiveness and controversy respect to its efficacy, surgical intervention remains the main treatment modality. Nevertheless, due to advances in the understanding of ORNJ physiopathology, new treatment alternatives such as the combination of pentoxifylline with tocopherol (PENTO) have emerged. The aim of this systematic review was to assess the reported efficacy of PENTO for the treatment of ORNJ. Material and Methods: Studies were search using Pubmed, The Cochrane Library, Scopus, and Web of Science data bases following the PRISMA guidelines. Inclusion criteria were cohort, case series, randomized or non-randomized clinical studies published in English including human subjects who received PENTO as treatment for ORN of the jaws. Results: Eleven articles met the inclusion criteria and were included for data analysis. All studies reported patients with complete mucosal coverage with no exposed bone (considered healthy) after PENTO treatment, ranging from 16.6% to 100% of the patients, depending on the study. Clinical improvement or disease stabilization was reported between 7.6% and 66.6% of studied individuals, while disease progression was seen in only 5 studies involving 7.6 - 32% of patients.
CONCLUSIONS
PENTO treatment achieved a complete disease control in a significant number of patients in all studies. However, there is no standardized protocol for administering the therapy. It is necessary to determine the pharmacological doses and to evaluate the benefits of adding antibiotics and clodronate. Good quality clinical trials are needed to develop a successful algorithm for the management of ORN of the jaws.

Review
Nuclear protein of the testis (NUT) carcinoma is a rare, undifferentiated carcinoma that is characterized by NUTM1 gene rearrangements. Patients with NUT carcinoma have an overall survival of approximately 5% at 5 years despite a multimodal treatment approach. This report illustrates the management of mandibular NUT carcinoma in a pediatric patient, complemented by a systematic review of head and neck NUT carcinoma. A 5-year-old female presented with an enlarging jaw mass that was diagnosed as BRD4-NUTM1 carcinoma and was treated with hemimandibulectomy and chemoradiation. She remains disease-free 21 months after completion of therapy. A total of 63 patient cases reported in 34 articles were identified in the review. Only 26.9% (14/52) of tumors were correctly diagnosed initially as NUT carcinoma, whereas 73.1% (38/52) were incorrectly diagnosed as another malignancy; the initial diagnosis was not reported for 11 patients. The mandibular tumor subtype was among the rarest reported (n = 1; 1.6%). Combination therapy, including surgery and chemoradiation, was the most common treatment (55.2%). The patient case presented here is a novel case of pediatric mandibular NUT carcinoma. Due to the poor overall survival of patients with NUT carcinoma, aggressive upfront resection with 2-cm margins followed by adjuvant chemoradiation is advocated.

Comparative Study
Dentinogenic ghost cell tumor (DGCT) and ghost cell odontogenic carcinoma (GCOC) form a spectrum of rare benign and malignant odontogenic neoplasms, respectively. The aim of this study was to perform a comparative systematic review of the clinicopathological, genetic, therapeutic, and prognostic features of DGCT and GCOC. The electronic search was performed until December 2020 on seven electronic databases. Case reports, series, and research studies with enough histopathological criteria for diagnosis and all genomic studies were included. Both DGCT and GCOC showed a male prevalence (p = 0.043), with mandibular and maxillary predilections, respectively (p = 0.008). Peripheral DGCT (DGCTp) affected most elderly people (p < 0.001), and central DGCT (DGCTc) and GCOC occurred mainly in younger individuals. Unilateral enlargement of maxilla or mandible was the most common clinical sign associated with a radiolucent or mixed image. Ameloblastomatous epithelium was often present in both neoplasms. Basaloid and large cells with vesicular nuclei were also frequently seen in GCOC. β-catenin expression and mutations (CTNNB1 gene) were found in DGCT and GCOC. Conservative surgery was mostly used for DGCTp, while radical resection was chosen for DGCTc and GCOC. High recurrence rates were found in DGCTc and GCOC. Metastasis occurred in 16.7% of GCOC cases and the 5-year survival rate was 72.6%. DGCT and GCOC share numerous clinicopathological features and demand a careful histopathological evaluation, considering the overlap features with other odontogenic tumors and the possibility of malignant transformation of DGCT. A strict regular post-operative follow-up is mandatory due to high recurrence rates and metastatic capacity in GCOC.
