The impact of COVID-19 pandemic in patients with a diagnosis of Oral Lichen Planus: Pain perception and psychological profile analysis.

OBJECTIVES: To assess the impact of COVID-19 in patients affected by OLP, in terms of level of pain, stress, depression and anxiety and their impact on the clinical manifestation of the disease. MATERIAL AND METHODS: A longitudinal design was employed. Psychometric evaluations of anxiety, stress, and depression were conducted using the DASS21 scale, while pain levels were measured using the VAS scale. Clinical diagnosis and phenotype evaluation were performed. RESULTS: The study included 24 patients with an average age of 62.9 years, with 70.8% presenting erosive OLP. Results revealed a significant worsening of anxiety, stress, and depression scores during the pandemic. Pain level (1.5 ± 1.2 pre-pandemic VS 3.8 ± 1.1 during the pandemic, p < 0.0001) was also negatively affected. CONCLUSIONS: These findings highlight the potential interplay between psychological stress and oral health conditions, emphasizing the need for a comprehensive understanding of OLP's complex etiology and its response to external stressors. CLINICAL RELEVANCE: Multidisciplinary care strategies to address both physical and psychological aspects of OLP patients is recommended following the present findings. Further research is warranted to confirm these observations in larger multicenter studies and to guide tailored guidance approaches for OLP patients during challenging times.

Oroantral Communications: Clinical Efficacy of a Double-layered Technique With/Without the Palatal Connective Tissue Flap: A Superiority, Single-center, University-based Randomized Clinical Trial.

The aim of this study was to compare the clinical results of combining a pedicle connective palatal flap coupled with the trapezoid buccal flap against the buccal flap alone in the closure of the oroantral fistula. Individuals with oroantral communication were consecutively included and eventually randomly allocated into 2 groups. In the group test, oroantral fistula was treated with the association of a buccal flap with a pedicle palatal connective tissue flap; in group control, a classic buccal sliding flap was performed. Patients' outcomes were recorded at 48 hours, 1 week, 2 weeks, and 1 month after surgery for assessment of primary (success rate) and secondary endpoints, such as experienced pain, discomfort, and complications. The success rate was 96.6% for the test group and 86.6% for the control group. No significant difference between the 2 groups could be observed regarding discomfort and pain. More pronounced pain was detected in the test group during the early healing period. This surgical procedure was demonstrated to be successful, with a high success rate and low patient discomfort.

Accuracy and Security Analysis of a Cranio-Maxillofacial Plastic Surgery Robot Equipped With Piezosurgery in Genioplasty.

ABSTRACT: This study aims to verify that the craniofacial plastic surgery robot with piezosurgery is more accurate and safer than traditional operations in genioplasty. This study chose data from the Digital Plastic Surgery of Plastic Surgery Hospital in the Chinese Academy of Medical Sciences and Peking Union Medical College. The CT data of the patient's skull were reconstructed in the software, and the authors designed the measurement index. The surgical plan was designed as an ideal scheme (control group). Patients underwent traditional surgery according to the preoperative surgery plan (clinical group). Guided by surgical navigation, the osteotomy was operated on patients' same size plaster model using the surgery robot equipped with a piezosurgery (robot group). At last, the accuracy was calculated by CT data. There was no significant difference between the robotic group and control groups in the postoperative measurement index (P < 0.05). There was no significant difference between the robotic group and the control group ( P > 0.05) in the line of osteotomy, but there was a significant difference between the clinical group and the control group in the line of the osteotomy.

A new framework to identify dental emergencies in the COVID-19 era.

In order to reduce the spread of COVID-19 (Coronavirus Disease 2019), it is crucial to take extraordinary prevention and safety measures in dental offices, and to defer all elective and non-urgent procedures. Dental emergencies are defined through oral symptoms but, the systemic and psychological conditions of each patient should be considered. The present short communication proposes a multilevel evaluation (oral, systemic and psychological) and risk assessment score for the management of dental emergencies following the SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) outbreak. A comprehensive categorization and score scale assessment for dental emergencies allows a better identification of patient's treatment needs and avoids unnecessary contact between dental health care providers and patients during the SARS-CoV-2 pandemic.

Blastic plasmacytoid dendritic cell neoplasm: a rare case of gingival lesion with leukaemic presentation.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare haematological malignancy with an aggressive clinical course. It has been recognised as a distinct entity in the WHO 2008 classification of haematolymphoid neoplasm. This disease usually presents with cutaneous involvement as the first manifestation, with subsequent or simultaneous spread to bone marrow and peripheral blood with leukaemic dissemination. Gingival lesion as the first manifestation, in the absence of a cutaneous lesion, is an uncommon presentation of this rare disease. We report a case of an elderly woman, aged 84 years, who presented with a lump on the mandibular gingiva and ipsilateral otalgia without any cutaneous lesion and associated with an highly aggressive and rapid leukaemia. This case is an addition to the handful of those cases of BPDCN which presents without cutaneous involvement, but it is exceedingly rare for clinical features that make it a unique case in the literature.

Correlation Between Dysphagia and Malocclusion in Rett Syndrome: A preliminary study.

OBJECTIVES: Rett syndrome (RS) is a severe neurological developmental disorder characterised by stereotypical hand movements, epileptic seizures, craniofacial dysmorphism and digestive dysfunction. This study aimed to examine the correlation between the severity of malocclusion and dysphagia in patients with RS. METHODS: This preliminary study was conducted at the Ear, Nose & Throat Clinic of the University Hospital of Siena, Siena, Italy, from January 2014 to December 2017. A total of 56 patients with RS were examined and grouped according to the severity of dysphagia (absent, mild, moderate or severe) and malocclusion (<2 mm, 2-3 mm, 3-4 mm or >4 mm). RESULTS: All of the patients were female and the mean age was 11.3 years. Eight (14.3%) patients had mild, 18 (32.1%) had moderate and 30 (53.6%) had severe dysphagia. Four (7.1%) patients had <2 mm occlusion, 10 (17.9%) had 2-3 mm occlusion, 26 (46.4%) had 3-4 mm occlusion and 16 (28.6%) had >4 mm occlusion. Mild dysphagia was observed in 100% and 40% of patients with <2 and 2-3 mm malocclusion, respectively, while moderate dysphagia was present in 60% and 38.5% of patients with 2-3 and 3-4 mm malocclusion, respectively. Severe dysphagia was observed in 28.6% and 87.5% of patients with 3-4 and >4 mm malocclusion, respectively. There was a significant correlation between dysphagia and malocclusion severity (P <0.001). CONCLUSION: A higher degree of malocclusion was associated with more severe dysphagia among a cohort of patients with RS.

A case of bisphosphonate-related osteonecrosis of the jaw with a particularly unfavourable course: a case report.

Bisphosphonates are drugs used to treat osteoclast-mediated bone resorption, including osteoporosis, Paget disease, multiple myeloma, cancer-related osteolysis, and malignant hypercalcemia. The use of these drugs has increased in recent years as have their complications, especially bisphosphonate-related osteonecrosis of the jaw (BRONJ), which more frequently affects the mandible. Here we report a case of BRONJ with a particularly unfavorable course due to cervical inflammation that developed into necrotizing fasciitis, followed by multiorgan involvement leading to septic shock and death.

A rare case of osteonecrosis of the jaw related to imatinib.

Osteonecrosis of the jaw (ONJ) is commonly described as an adverse effect of the use of bisphosphonates. A few cases of ONJ associated with tyrosine kinase inhibitors (sunitinib, imatinib) have been reported in the literature and usually they occurred in patients simultaneously treated with bisphosphonates. We report an atypical case of ONJ related only to imatinib. A 72-year-old male patient was treated with imatinib for metastases from gastrointestinal stromal tumors (GISTs). The patient developed ONJ after 22 months of imatinib only therapy. During his whole life, the patient had never been treated with bisphosphonates or radiotherapy. Microscope examination of the tissues confirmed the clinical diagnosis of diffuse osteonecrosis and showed absence of neoplastic cells. Thus, secondary localisations from GISTs were ruled out. Osteonecrosis of the lower jaw appeared 22 months after initial and exclusive therapy with imatinib. Therefore, imatinib monotherapy can induce ONJ in patients that have never been treated with bisphosphonates or radiotherapy.

Stevens-Johnson syndrome and abuse of anabolic steroids.

Stevens-Johnson syndrome (SJS) is characterized by mucocutaneous tenderness and typical hemorrhagic erosions, erythema and epidermal detachment presenting as blisters and areas of denuded skin. SJS is often observed after drug use as well as after bacterial or viral infections. Several drugs are at high risk of inducing SJS, but there are no cases in the English literature regarding anabolic steroid use triggering SJS. In our paper, we describe a case in which use of anabolic androgenic steroids (AAS) was associated with SJS. The patient participated in competitive body-building and regularly took variable doses of AAS. Initial symptoms (headache, weakness, pharyngodynia, and fever) were ignored. After a week he presented to the Emergency Department with a burning sensation on the mouth, lips, and eyes. Painful, erythematous, maculopapular, and vesicular lesions appeared all over the body, including on the genitals. During hospitalization, he also developed a cardiac complication. The patient had not taken any drugs except AAS.

Unusual complications caused by lipoma of the tongue.

Lipoma is the most common, benign, soft tissue, mesenchymal tumour and is composed of mature adipose tissue. It is infrequent in the oral cavity (approximately 0.3% of all tongue neoplasias). We describe the case of a 68-year-old man with a swelling at the tongue edge and tongue dysesthesia. Medical history, clinical assessment, radiographic images, and cytological analysis enabled specialists to classify this neoplasia as a lipoma. The patient recovered fully after surgical excision of the affected area, and the neuralgic symptoms regressed. Surgical excision is an elective treatment; however, accurate differential diagnosis, histological examination, and follow-up are required.

Gingival Leiomyosarcoma in a Young Woman: Case report and literature review.

Leiomyosarcoma (LMS) is a rare mesenchymal malignancy, of which 3-10% of cases occur in the head and neck region. We report a 22-year-old woman who was referred to the University Hospital of Siena, Italy, in 2016 with an ostensibly benign asymptomatic lump on the mandibular gingiva. The lesion grew rapidly, causing otalgia in the right ear. An excisional biopsy was performed and primary LMS was diagnosed histologically. Subsequently, the patient underwent radical re-excision of the perilesional mucosa, a partial bone resection and the extraction of four teeth. No recurrences or metastases were detectable at a 20-month follow-up. This report discusses the differential diagnosis of LMS with regards to other benign and malignant lesions and reviews the recent literature on primary and secondary oral LMS. Due to its innocuous clinical features-including its asymptomatic nature and presentation at a young age-this aggressive malignancy can go undetected; therefore, an early histopathological diagnosis is crucial.

A comparative immunohistochemical and immunophenotypical study on lymphocytes expression in patients affected by oral lichen planus.

BACKGROUND: Oral lichen planus (OLP) is an immune-mediated mucocutaneous disease of uncertain aetiology. OLP has many manifestations: reticular, erosive, atrophic, plaque like, papular, bullous, with unique etiopathogenetic working. The purpose of this study is to find a link between different clinical types of lichen and the alterations of lymphocytes on peripheral blood and oral mucosa. MATERIALS AND METHODS: A total of 21 patients were enrolled in this study. The mean age of patients was 53.82 years, between 31 and 78 years. OLP Diagnosis was afterwards confirmed by histopathology. Selected patients underwent to clinical evaluation, lesion characterization, incisional biopsy, samples histological analysis, peripheral blood collection. Blood specimens were submitted to cell count determination with differential, characterization of populations and circulating lymphocyte subpopulations using monoclonal antibodies in flow cytometry. Referring to the clinical presentation of lesions, patients were divided in two groups: red lesions (RL) and white lesions (WL) and compared with an age-matched control group. RESULTS: The results of the immunophenotypic study showed correlation between WL and the expression of CD19 lymphocytes (r = 0.693, P = 0.0005). The results of immunohistochemical study performed on histological specimens showed a significant correlation between RL group and expression of all lymphocyte tested (CD3 r = 0.722 P = 0.0002, CD4 r = 0.579 P = 0.0060, CD56 r = 0.513 P = 0.0173, CD8 r = 0.548 P = 0.0102). CONCLUSIONS: We assume there is the responsibility of the expression of lymphocytes, not only type but also as quantity, in determining RL or WL manifestation of OLP. Circulating lymphocytes may have a role, too.

Metastatic carcinoma presenting as neuralgia involving the trigeminal nerve.

Breast carcinoma is the leading cause of cancer death in women. Metastatic tumours of the oral cavity arising from breast cancer (and other forms of cancer) may be similar to hyperplastic or reactive lesions. They are uncommon and typically appear when various organs have already been affected by the neoplasia. A 53-Year-old woman presented with "discomfort" in her left mandible, specifically, swelling of recent onset accompanied by progressive loss of sensation. The mandibular swelling had been preceded by neuralgia involving the trigeminal nerve. Biopsy and histologic examination of the intrabony mass revealed ductal adenocarcinoma with infiltration of bone and stromal tissues. The lesion was determined to be metastatic from previously undiagnosed breast cancer. The neuralgia was also related to a metastatic lesion.

Cervical necrotizing fasciitis of odontogenic origin involving the temporal region--a case report.

Necrotizing fasciitis (NF) is a soft-tissue infection, usually polymicrobial, that causes necrosis of fascia and subcutaneous tissue while sparing skin and muscle. We report a case of cervical NF complicating dental infection in a 50-year-old woman, who presented with infection involving mucosa of the right mandible and temporal muscle, and masticator spaces, requiring extensive surgery and antibiotic therapy. Prompt diagnosis and immediate aggressive surgical debridement of all compromised tissues are critical to reducing morbidity and mortality in these rapidly progressive infections.

Polydactyly with ectodermal defect, osteopenia, and mental delay.

Five members from 3 generations, including a 35-year-old woman and her 2 sons, both mentally impaired to a different degree, were studied in a tertiary care hospital. Anamnestic, clinical, neurological, and radiological evaluations were used to describe phenotypes. A and B postaxial polydactyly, transmitted likely as autosomal dominant, was associated with an extensive variability of phenotypic features: (1) cutaneous syndactyly, (2) nail-teeth dysplasia, (3) osteopenia, and (4) mental delay. The likelihood that the constellation of observations we report here is caused by mutation of a single gene that subsequently affects multiple physiological activities, although fascinating, remains to be proven. Instead, we hypothesize that it likely develops as a contiguous gene syndrome.

New neurocutaneous syndrome with defect in cell trafficking and melanosome pathway: the future challenge.

OBJECTIVE: Case study of a CNS impairment lacking in presumptive cause; case presents with a clinical phenotype encompassing multiple differently expressed and combined symptoms, as well as a subtle skin defect. MATERIALS AND METHODS: A 6-year-old male with apparently isolated mental delay, speech delay, attention deficit/hyperactivity disorder, epilepsy, and subtle and insignificant skin dyschromias. The patient underwent a systematic evaluation, including clinical history; medical, neurological and ophthalmologic examinations. Skin, teeth, nails, hair and sudation were examined for defects. Routine laboratory tests for blood, urine, were performed. The proband had thyroid function tests, electrocardiography, genitourinary system and abdominal examinations. Special examinations pertaining to mental performance, biochemistry, chromosome studies, imaging and electrodiagnostic studies, and skin biopsy were also performed. RESULTS: Investigators ruled out genetic syndromes, congenital infections, fetal deprivation, perinatal insults, intrauterine exposure to drug abuse, and postnatal events such as CNS infections as possible common causes of brain impairment. Being all further test negative, the patient exhibited an ultrastructural defect of the skin, identical to that previously described [Buoni S, Zannolli R, de Santi MM, Macucci F, Hayek J, Orsi A et al. Neurocutaneous syndrome with mental delay, autism, blockage in intracellular vesicular trafficking and melanosome defects. Eur J Neurol 2006;13:842-51], suggesting that some cell compartments, such as rough endoplasmic reticulum, lysosomes, Golgi apparatus, and the vesicular zone (racket) of Birbeck granules, sharing similar components, can be altered, resulting in a common defect in cell trafficking, associated to melanosome defects. CONCLUSIONS: This new devasting, ultrastructural phenotype accompanied by apparently unspecific and mixed neurological symptoms should represent a future challenge to finally discover the pathogenesis of many childhood CNS symptoms, that currently seem to lack any apparent cause.

Hypohidrotic ectodermal dysplasia and intrathoracic neuroblastoma.

We report a 6-year-old girl with a subtle form of hypohidrotic ectodermal dysplasia and a phenotype consisting of curly hair, a round face, a stocky build, and obesity, which was associated with intrathoracic neuroblastoma. Although this new association could be a chance occurrence, its description may alert physicians to look for similar combinations and report these, as it may lead to better syndrome delineation, and patient care.

Kabuki syndrome with trichrome vitiligo, ectodermal defect and hypogammaglobulinemia A and G.

We report a unique combination of symptoms in a case of Kabuki syndrome (KS), a multiple malformation/mental retardation syndrome that has a prevalence of 1:32,000 to 1:86,000. The patient was a mentally delayed 12-year-old male with trichrome vitiligo, ectodermal defect, and hypogammaglobulinemia A and G. This unique combination of signs, described here for the first time, indicates that KS comprises multiple deficits that affect not only the brain, but ectoderm-derived structures and the immune system as well. Our report may provide important clues for understanding the pathogenesis of the KS.
