Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective To explore the value of Chinese thyroid imaging reporting and data system(C-TIRADS)combined with intranodular and perinodular stiffness for distinguishing benign and malignant thyroid nodules.Methods Data of routine ultrasound and ultrasonic shear wave elastography(SWE)in 117 patients with thyroid nodules confirmed by fine needle aspiration cytology(FNAC)and/or surgical pathology were retrospectively analyzed.The nodules were classified according to C-TIRADS and SWE parameters of nodules and surrounding 2 mm glands measured with SWE technique,including Young's modulus of thyroid nodules(E)and perinodular glandular(Eshell)(the maximum[Emax/Eshellmax],the mean[Emean/Eshellmean]and the minimum[Emin/Eshellmin]as well as standard deviation[ESD/EshellSD]values).Then receiver operating characteristic(ROC)curve was drawn,and area under the curve(AUC)was calculated to assess the efficacy of C-TIRADS,SWE and the combination for differentiating benign and malignant thyroid nodules.Results Totally 117 thyroid nodules of 117 patients were enrolled,including 50 benign and 67 malignant ones.SWE parameters of malignant thyroid nodules were higher than those of benign ones(all P＜0.001).AUC of C-TIRADS for differentiating benign and malignant thyroid nodules was 0.736,with sensitivity of 79.10％,specificity of 68.00％and accuracy of 74.36％.AUC of Emax,Emean,Emin and ESD was 0.816,0.752,0.664 and 0.705,respectively,of Emax was the highest.AUC of Eshellmax,Eshellmean,Eshellmin and EshellSD was 0.834,0.804,0.693 and 0.697,respectively,of Eshellmax was the highest,which was not statistically difference with that of Emax(Z=1.044,P=0.297).AUC of C-TIRADS+Emax and C-TIRADS+Eshellmax was 0.835 and 0.843,respectively,being not significantly different(Z=0.574,P=0.566)but higher than that of C-TIRADS(AUC=0.736,Z=2.510,2.230,both P＜0.05),with diagnostic specificity and accuracy both higher than those of C-TIRADS(all P＜0.05).Conclusion C-TIRADS combined with intranodular and perinodular stiffness could be used to effectively distinguish benign and malignant thyroid nodules,which might improve diagnostic efficiency of C-TIRDAS.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.

The Ehlers-Danlos syndrome(EDS)is a rare inherent connective tissue disorder.The prev-alence of EDS in the population is estimated at one out of ten thousand to one out of a hundred thousand.The vascular EDS(vEDS)are rare among the subtypes but are the worst in prognosis.The article reports a case of vEDS admitted to the hospital.The patient was a young man complaining of a sudden onset of aphasia in right hemiparalysis and severe left abdominal pain for unknown reasons.The diagnosis was made after the genetic testing.The patient suffered from vEDS.Then,the multi-disciplinary team(MDT)made a treatment plan tailored to this young patient.The complexity in classification and delusive presentations of the EDS make the correct diagnosis very challenging.This article hopes to report this case and to share the experiences to the bet-ter understanding of this disease.

Primary ciliary dyskinesia(PCD)is a rare monogenic disorder primarily associated with structural and functional abnormalities of motile cilia.It is typically inherited in an autosomal recessive pattern.The disease affects multiple organs,and the variability in clinical phenotypes,along with genetic heterogeneity significantly complicates its diagnosis.Although the application of clinical exome sequencing has significantly improved the diagnostic rate of PCD,more than 30％of patients are still unable to obtain a definitive diagno-sis.This article reviews and discusses the pathogenesis,diagnostic methods,and expanding genetic diag-nostic approaches for patients with PCD that are negative for exome sequencing.The aim of this article is to assist clinicians in selecting more advanced emerging genetic testing technologies,with the hope of increasing the positive diagnostic rate of PCD,deepening the understanding of its genetic pathogenesis,and laying a foundation for the practice of gene therapy in the future.

Objective:To explore the clinical effects of the best evidence-based practice plan for rehabilitation exercises in patients undergoing surgery for lumbar spinal stenosis (LSS) .Methods:Guided by the evidence-based practice model of the Joanna Briggs Institute (JBI) Center for Evidence-Based Healthcare in Australia, the best evidence was combined with the clinical context to develop quality review indicators for clinical practice. In December 2022, a baseline review was conducted with 30 patients undergoing surgery for LSS (before evidence application). From December 2022 to February 2023, the baseline review results were analyzed to identify facilitating and obstructive factors between the current status and the review indicators, and improvement strategies were implemented based on available resources. In February 2023, another 30 patients (after evidence application) were selected to evaluate the post-application effects. The Japanese Orthopedic Association (JOA) score, Oswestry Disability Index (ODI), Tampa Scale for Kinesiophobia (TSK) score, General Self-Efficacy Scale (GSES) score, and quality of life scores were compared between the two groups at 24 hours, 1 month, 3 months, and 6 months postoperatively. The execution rate of clinical quality review indicators and the knowledge scores on rehabilitation exercises of 25 nurses before and after training were also compared.Results:There were no statistically significant differences in JOA scores, ODI, TSK scores, GSES scores, and quality of life scores between the two groups at 24 hours postoperatively ( P > 0.05). However, there were statistically significant differences in these scores at 1, 3, and 6 months postoperatively ( P< 0.01). After evidence application, the execution rate of seven clinical quality review indicators improved, and the knowledge scores on rehabilitation exercises of the 25 nurses increased significantly ( P< 0.05) . Conclusions:The evidence-based practice for rehabilitation exercises in patients undergoing surgery for LSS is safe and feasible. It standardizes evidence-based nursing practice behavior, enhances nurses' knowledge levels, effectively improves postoperative lumbar function, promotes physical rehabilitation, and enhances the quality of life.

Odontogenic maxillary sinusitis(OMS)is a subtype of maxillary sinusitis(MS).It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion.Due to the lack of unique clinical features,OMS is difficult to distinguish from other types of rhinosinusitis.Besides,the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis.Its current diagnosis and treatment are thus facing great difficulties.The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS.However,this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality.Based on systematically reviewed literature and practical experiences of expert members,our consensus focuses on characteristics,symptoms,classification and diagnosis of OMS,and further put forward multi-disciplinary treatment decisions for OMS,as well as the common treatment complications and relative managements.This consensus aims to increase attention to OMS,and optimize the clinical diagnosis and decision-making of OMS,which finally provides evidence-based options for OMS clinical management.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.
