ABSTRACT
Pleomorphic adenoma is a non-cancerous neoplasm that develops in the salivary glands. Originating from minor salivary glands, it is extremely uncommon and primarily affects females. The peak incidence is observed between 40 and 60 years of age. It usually presents as a slowly growing, painless, solid tumor that does not cause ulcers on the overlying mucosa. Here, a 47-year-old woman experienced repeated swelling on the buccal mucosa following surgical extraction of a pleomorphic adenoma three years ago. The swelling was solid with clearly defined boundaries. An excisional biopsy was conducted under general anesthesia, resulting in total mass removal. The histological evaluation revealed the existence of a recurring pleomorphic adenoma. This instance emphasizes the significance of addressing this entity as a potential etiology for persistent painless and intraoral swellings.
ABSTRACT
Background The visual analogue scale (VAS) has been used as a diagnostic tool for the evaluation of the severity of olfactory and gustatory dysfunction (OGD) caused by SARS-CoV2 infection. The main objective of the present study was the evaluation of OGD with VAS in COVID-19-positive patients in Northwestern Greece and its possible association with the patients' self-reported symptoms of olfactory and gustatory dysfunction. Methods The presence of olfactory and gustatory symptoms and their severity were assessed by questionnaire along with the use of specific odorants and tastant ingredients, in three time periods: prior to COVID-19, during COVID-19 (initial diagnosis) and post-COVID-19 disease (at four weeks from disease onset). Three hundred COVID-19-positive patients (home-quarantined and hospitalized) tested with RT-PCR test in the University Hospital of Ioannina Greece were included in this study. Statistical analysis was performed on SPSS Statistics 26.0 (IBM Corp., Armonk, NY) Results Out of a total of 300 patients, 146 and 190 patients had mild hyposmia and hypogeusia respectively, followed by patients with severe hyposmia or hypogeusia (118 and 88 respectively), at the time of COVID-19 onset (initial diagnosis). An increase in the number of patients with recovery of symptoms was observed during the follow-up period, during which only eight patients had non-resolving severe symptoms (six patients with hyposmia and two with hypogeusia). On further analysis, a statistically significant association was found between the severity of symptoms (assessed by VAS score) and the self-reported symptoms of sensory dysfunction by the patients. There was a significant association between the groups of patients with mild hyposmia and patients that reported no loss of smell; between the patients with moderate hyposmia and the patients who reported "loss of smell"; and between the patients with severe hyposmia and the group of patients who reported a loss of smell, at the COVID-19 onset period. Similarly, patients with mild hyposmia were associated with those that reported a loss of smell at the same time. The severity of hyposmia was also associated with the reported symptom of "loss of taste" at the time of COVID-19 diagnosis. Similar findings were observed regarding the severity of hypogeusia and the reported symptom of "loss of taste" among the groups of patients. Finally, the severity of hypogeusia was associated with smell loss at the time of initial diagnosis of the infection. Conclusion Similar to the literature data, our findings indicate that hyposmia and hypogeusia are common symptoms of COVID-19 disease with varying severity. In our study, most of the patients exerted a complete recovery of these OGD symptoms. In addition, we found an association between olfactory dysfunction and self-reported sensory of taste as well as gustatory dysfunction and sensory of smell. Finally, we found that the VAS score was a reliable diagnostic tool in the estimation of OGD in this cohort of patients. However, our results need to be confirmed by larger-scale trials.
ABSTRACT
Fibrous dysplasia (FD) is a rare, benign, chronic, slowly progressive bone disorder characterized by the replacement of normal bone and bone marrow by fibrous tissue, leading to deformity, pain and functional impairment. It was considered a disease of unknown etiology, uncertain pathogenesis and diverse histopathology. It was later discovered that was caused by a non-heritable activating mutation in the á-subunit gene of the stimulatory G-protein coding gene. Temporal bone involvement is the least frequently reported type, especially in children. The purpose of the current manuscript was to report a rare case of fibrous dysplasia of the left temporal bone of a 17-year-old child who came to the emergency room of our hospital with otalgia and progressive hearing loss on the left ear.
ABSTRACT
Objectives: To provide a detailed description and evaluation of therapeutic techniques for the management of nasal valve in rhinoseptoplasty. Method:An extensive review of the international bibliography has been conducted to highlight published articles on nasal valve pathology and therapeutic measures to address it. Results:To date, many techniques have been described for increasing the cross-sectional area of the nasal valve. Selection of the appropriate technique poses a significant challenge to the nasal valve surgeon. Long-term correction of NVD requires surgical intervention. Correction typically involves the use of various grafts or suture techniques to enlarge and/or support the nasal valve. Selection of the appropriate technique depends on the location and type of dysfunction (dynamic/static). Conclusion:The nasal valve plays an important role in nasal airflow. It is important for the otolaryngologist not only consider, but also fully evaluate the nasal valve when seeing a patient with nasal obstruction. If it is not the primary cause of obstruction, it is often a contributing factor. If NVD is discovered, it should be addressed during surgical intervention (functional rhinoplasty) to avoid a suboptimal outcome.
ABSTRACT
Human papillomavirus (HPV)-mediated cervical carcinogenesis represents a well analyzed model of viral implication in epithelial malignant transformation. Mechanisms of high risk (HR) HPV-related infection seem to demonstrate a similar action regarding its implication in head and neck (HN) carcinomas, predominantly in squamous cell carcinoma (SCC) histological type. The prevalence of HR HPV subtypes - mainly HPV16 - is characterized by a broad geographic heterogeneity. Furthermore, HPV-associated HNSCCs demonstrate differences regarding sexual, molecular, epidemiological, and prognostic features compared to alcohol and tobacco dependent ones. Based on these differences, HPV-derived HNSCC appear to be a specific well-defined entity mostly affecting young to middle-aged - male mainly - non-smokers. This is a strong reason of detecting an increased HR-HPV DNA levels -due to viral transmission - in oropharyngeal and laryngeal anatomic regions. Additionally, different response rates to chemoradiation and targeted therapeutic regimens are another significant field for handling these SCC malignancies in the corresponding patients. In the current special article we explored the role of HPV-related carcinogenesis in oropharyngeal and laryngeal SCC focused on the latest molecular aspects.
