Its pathogenesis is complex and has a high degree of malignancy. Recurrence and metastasis often lead to poor prognosis. MicroRNAs are a type of single stranded small molecule RNA with only 18 - 25 nucleotides, which can regulate the expression of various genes and participate in the occurrence and development of tumors. Studies have found that microRNA expression profiling can serve as a reliable and stable biological indicator for early diagnosis and prognosis of tumors. This article provides a review of the research status of MicroRNAs in squamous cell carcinoma of the tongue.展开更多

Physical examination and the TBT were performed, followed by radiological imaging(facial X-ray or computed tomography [CT]). The diagnostic accuracy was calculated for individuals and a combination of clinical findings at predicting maxillary and mandibular fractures.RESULTS: A total of 98 patients were identified, of whom 31.6% had maxillary fractures and9.2% had mandibular fractures. The combination of malocclusion, tenderness on palpation and swelling with positive TBT had 100% specificity to detect maxillary and mandibular fractures. In the absence of malocclusion, the combination of tenderness on palpation and swelling with positive TBT produced a specificity of 97.8% for maxillary fracture and a specificity of 96.2% for mandibular fracture. A clinical decision tool consisting of malocclusion, tenderness on palpation, swelling and TBT revealed a specificity of 100% and a positive predictive value of 100%.CONCLUSION: The clinical decision tool is potentially useful to rule out mandibular fractures,thus preventing unnecessary radiation exposure.展开更多

[Methods]The expression level of IRF1 in tongue squamous carcinoma tissues was detected by real-time quantitative PCR and immunohistochemistry. Plasmids for overexpression and knockdown of IRF1 were constructed. The effects of overexpression and knockdown of IRF1 on the proliferation, invasion and migration of Tca8113 cells were examined in Tca8113 cells. [Results] IRF1 expression was abnormally reduced in tongue squamous carcinoma tissues, and both real-time quantitative PCR and immunohistochemistry showed significantly lower expression than that of paraneoplastic controls. The overexpression and knockdown plasmids of IRF1 were successfully constructed. Growth curve assays showed that overexpression of IRF1 inhibited the proliferation of Tca8113 cells, while knockdown of IRF1 promoted the proliferation of Tca8113 cells. Scratch assay showed that overexpression of IRF1 inhibited the migration of Tca8113 cells, while knockdown of IRF1 promoted the migration of Tca8113 cells. Transwell assay showed that overexpression of IRF1 inhibited the invasion of Tca8113 cells, while knockdown of IRF1 promoted the invasion of Tca8113 cells. [Conclusions] In the development of tongue squamous carcinoma, IRF1 functions as an anti-oncogene, and the expression level of IRF1 was reduced in tongue squamous carcinoma tissues.展开更多

Using videofluoroscopic(VF) images, we can evaluate swallowing function, but it is extremely difficult to quantitatively evaluate the oral phase. Recently, several studies have tried to quantitatively assess tongue function by analyzing tongue movement on VF images, to measure tongue thickness by ultrasonography, and to measure tongue pressure as surrogate for tongue strength. In this review article,the current state of quantitative assessments of tongue function for identification and management of dysphagia in patients with neuromuscular and other neurological disorders(NNMD) has been outlined. Disturbed bolus transport in patients with NNMD has been quantitatively measured on VF images by analyzing tongue base movement and bolus transport from the mouth to the pharynx. Enlarged tongue in Duchenne muscular dystrophy patients were observed by measuring the transverse width of the tongue on ultrasound. Tongue pressures that were measured using a handheld probe in NNMD patients were less than half of those in healthy subjects. More studies are needed to develop guidelines what types of tongue dysfunction give an indication of adjusting diet and introducing tube feeding to NNMD patients.展开更多

A clinical decision tool consisting of malocclusion, tenderness on palpation, swelling and TBT revealed a specificity of 100% and a positive predictive value of 100%.CONCLUSION: The clinical decision tool is potentially useful to rule out mandibular fractures,thus preventing unnecessary radiation exposure.
文摘Tongue image analysis is an efficient and non-invasive technique to determine the internal organ condition of a patient in oriental medicine,for example,traditional Chinese medicine(TCM),Japanese traditional herbal medicine,and traditional Korean medicine(TKM).The diagnosis procedure is mainly based on the expert’s knowledge depending upon the visual inspec-tion comprising color,substance,coating,form,and motion of the tongue.But conventional tongue diagnosis has limitations since the procedure is inconsistent and subjective.Therefore,computer-aided tongue analyses have a greater potential to present objective and more consistent health assess-ments.This manuscript introduces a novel Simulated Annealing with Transfer Learning based Tongue Image Analysis for Disease Diagnosis(SADTL-TIADD)model.The presented SADTL-TIADD model initially pre-processes the tongue image to improve the quality.Next,the presented SADTL-TIADD technique employed an EfficientNet-based feature extractor to generate useful feature vectors.In turn,the SA with the ELM model enhances classification efficiency for disease detection and classification.The design of SA-based parameter tuning for heart disease diagnosis shows the novelty of the work.A wide-ranging set of simulations was performed to ensure the improved performance of the SADTL-TIADD algorithm.The experimental outcomes highlighted the superior of the presented SADTL-TIADD system over the compared methods with maximum accuracy of 99.30%.

文摘Head and neck squamous cell carcinoma is the seventh most common cancer worldwide with high mortality rates.Amongst oral cavity cancers,tongue carcinoma is a very common and aggressive oral cavity carcinoma.Despite the implementation of a multimodality treatment regime including surgical intervention,chemo-radiation as well as targeted therapy,tongue carcinoma shows a poor overall 5-year survival pattern,which is attributed to therapy resistance and recurrence of the disease.The presence of a rare population,i.e.,cancer stem cells(CSCs)within the tumor,are involved in therapy resistance,recurrence,and distant metastasis that results in poor survival patterns.Therapeutic agents targeting CSCs have been in clinical trials,although they are unable to reach into therapy stage which is due to their failure in trials.A more detailed understanding of the CSCs is essential for identifying efficient targets.Molecular signaling pathways,which are differentially regulated in the CSCs,are one of the promising targets to manipulate the CSCs that would provide an improved outcome.In this review,we summarize the current understanding of molecular signaling associated with the maintenance and regulation of CSCs in tongue squamous cell carcinoma in order to emphasize the need of the hour to get a deeper understanding to unravel novel targets.

文摘Biomedical image processing is widely utilized for disease detection and classification of biomedical images.Tongue color image analysis is an effective and non-invasive tool for carrying out secondary detection at anytime and anywhere.For removing the qualitative aspect,tongue images are quantitatively inspected,proposing a novel disease classification model in an automated way is preferable.This article introduces a novel political optimizer with deep learning enabled tongue color image analysis(PODL-TCIA)technique.The presented PODL-TCIA model purposes to detect the occurrence of the disease by examining the color of the tongue.To attain this,the PODL-TCIA model initially performs image pre-processing to enhance medical image quality.Followed by,Inception with ResNet-v2 model is employed for feature extraction.Besides,political optimizer(PO)with twin support vector machine(TSVM)model is exploited for image classification process,shows the novelty of the work.The design of PO algorithm assists in the optimal parameter selection of the TSVM model.For ensuring the enhanced outcomes of the PODL-TCIA model,a wide-ranging experimental analysis was applied and the outcomes reported the betterment of the PODL-TCIA model over the recent approaches.
文摘BACKGROUND Tongue abscess(TA)is a very rare clinical condition and its treatment is very important.Surgical drainage is at the forefront in the treatment.Our study includes patients with tongue and tongue base abscesses.AIM To discuss the clinical and laboratory findings of these patients emphasizing the underlying causes and treatment options with the largest patient series in the English literature.METHODS We included patients with isolated TA who applied to our clinic between January 1,2020 and January 1,2023.Those who lack the recorded data,those who are not between the ages of 18-66,those who have not undergone surgery-interventional procedure,and those who have infection and/or abscess in another place were excluded from the study.RESULTS There were two female(18%)and nine male(82%)patients in our series consisting of 11 patients.Their ages ranged from 18 to 66,and the mean±SD was 48.63±16.3.Considering the localization of the abscess,three anterior abscesses(27%),two lateral abscesses(18%),and six abscesses at the base of the tongue(54%)were detected.CONCLUSION Tongue abscesses can cause acute upper airway obstruction and respiratory collapse.It may be necessary to act quickly for the tracheotomy procedure and this procedure can usually be performed under local anesthesia as intubation cannot be achieved.When we encounter an abscess in an unexpected organ,difficulties may be encountered in the management of the patient.
文摘BACKGROUND Angioedema is a disorder characterized by edema of the face,lips,tongue,and extremities due to increased vascular permeability.Angioedema of the tongue usually occurs bilaterally,and the incidence of unilateral angioedema of the tongue is rare.This study reports a rare case of unilateral angioedema of the tongue with no identifiable cause and repeated recurrence even after discontinuation of an angiotensin-converting enzyme inhibitor.CASE SUMMARY The patient was a 65-year-old woman with pre-existing hypertension and hyperlipidemia and had been receiving 20 mg/d of lisinopril.She was diagnosed with angioedema due to unilateral swelling of the tongue.No airway obstruction was observed,and the symptoms improved following the administration of 0.3 mg of epinephrine intramuscularly and 125 mg of methylprednisolone intravenously.Although lisinopril was discontinued,unilateral angioedema of the tongue continued to recur every 2-5 mo,with the symptoms improving following the administration of prednisolone and an antihistamine.Daily oral administration of 500 mg of tranexamic acid after dinner prevented the recurrence of angioedema.CONCLUSION Careful monitoring and identification of the underlying mechanism play a crucial role in the treatment of angioedema.

文摘[Objectives]This study was conducted to investigate the effect of interferon regulatory factor on the invasion and migration of tongue squamous carcinoma cells. [Methods]The expression level of IRF1 in tongue squamous carcinoma tissues was detected by real-time quantitative PCR and immunohistochemistry. Plasmids for overexpression and knockdown of IRF1 were constructed. The effects of overexpression and knockdown of IRF1 on the proliferation, invasion and migration of Tca8113 cells were examined in Tca8113 cells. [Results] IRF1 expression was abnormally reduced in tongue squamous carcinoma tissues, and both real-time quantitative PCR and immunohistochemistry showed significantly lower expression than that of paraneoplastic controls. The overexpression and knockdown plasmids of IRF1 were successfully constructed. Growth curve assays showed that overexpression of IRF1 inhibited the proliferation of Tca8113 cells, while knockdown of IRF1 promoted the proliferation of Tca8113 cells. Scratch assay showed that overexpression of IRF1 inhibited the migration of Tca8113 cells, while knockdown of IRF1 promoted the migration of Tca8113 cells. Transwell assay showed that overexpression of IRF1 inhibited the invasion of Tca8113 cells, while knockdown of IRF1 promoted the invasion of Tca8113 cells. [Conclusions] In the development of tongue squamous carcinoma, IRF1 functions as an anti-oncogene, and the expression level of IRF1 was reduced in tongue squamous carcinoma tissues.

文摘Tongue diagnosis is an important process to non-invasively assess the condition of a patient’s internal organs in traditional Chinese medicine(TCM)and each part of the tongue is related to corresponding internal organs.Due to continuing computer technological advances,especially the artificial intelligence(AI)methods have achieved significant success in tackling tongue image acquisition,processing,and classification,novel AI methods are being introduced in traditional Chinese medicine tongue diagnosis medical practices.Traditional tongue diagnose depends on observations of tongue characteristics,such as color,shape,texture,moisture,etc.by traditional Chinese medicine physicians.The appearance of the tongue color,texture and coating reflects the improvement or deterioration of patient’s conditions.Moreover,AI can now distinguish patient’s condition through tongue images,texture or coating,which is all possible increasingly with help from traditional Chinese medicine physicians under the traditional Chinese medicine tongue theory.AI has enabled humans to do what was previously unimagined:traditional Chinese medicine tongue diagnosis with feeding a large amount of tongue image and tongue texture/coating data to train the AI modes.This review focuses on the research advances of AI in TCM tongue diagnosis thus far to identify the major scientific methods and prospects.In this article,we tried to review the AI application in resolving the tongue diagnosis of traditional Chinese medicine on color correction,tongue image extraction,tongue texture/coating segmentation.
文摘BACKGROUND Sarcomatoid carcinoma is a rare subtype of non-small-cell lung cancer,commonly associated with locally advanced disease,early metastasis,and poor prognosis.Tongue metastasis from lung cancer is a rare condition that may occur in advanced stage of the disease.CASE SUMMARY The patient was a 70-year-old female with a history of resected pulmonary sarcomatoid carcinoma(PSC)who presented with subacute tongue swelling,imparting the clinical impression of a lingual abscess.However,histologic examination of the partial glossectomy revealed a high-grade,poorly differentiated spindle and epithelioid carcinoma consistent with metastatic PSC.CONCLUSION Although uncommon,clinicians should be cognizant of the possibility of a metastatic process to the tongue mimicking a benign or inflammatory process.A high index of suspicion for metastatic disease should be maintained when tongue swelling is observed in patients with a known history of PSC.
文摘Evaluation of oral function is useful for tracking longitudinal changes in swallowing function. Using videofluoroscopic(VF) images, we can evaluate swallowing function, but it is extremely difficult to quantitatively evaluate the oral phase. Recently, several studies have tried to quantitatively assess tongue function by analyzing tongue movement on VF images, to measure tongue thickness by ultrasonography, and to measure tongue pressure as surrogate for tongue strength. In this review article,the current state of quantitative assessments of tongue function for identification and management of dysphagia in patients with neuromuscular and other neurological disorders(NNMD) has been outlined. Disturbed bolus transport in patients with NNMD has been quantitatively measured on VF images by analyzing tongue base movement and bolus transport from the mouth to the pharynx. Enlarged tongue in Duchenne muscular dystrophy patients were observed by measuring the transverse width of the tongue on ultrasound. Tongue pressures that were measured using a handheld probe in NNMD patients were less than half of those in healthy subjects. More studies are needed to develop guidelines what types of tongue dysfunction give an indication of adjusting diet and introducing tube feeding to NNMD patients.
