Objective To discuss CT appearances and diagnosistic value of invasive thymoma.Methods CT findings in 13 cases of invasive thymoma proved by surgery and pathology were retrospectively analysed. Results In 13 cases, invasive thymomas all showed as solf tissue masses in anterier mediastinum on CT, of them, 10 cases were of heterogeneous density and irregular invasion to adjacent organs which the main CT findings were pleural implants in 3, cardiovascular involvement in 9 and abdominal invasion in 1 were found in 11 cases. Conclusion Conventional CT scan plays an important role in diagnosis and differential diagnosis of invasive thymoma.

[ABSTRACT]OBJECTIVETo investigate the efficacy and the related complications of combinedpostauricular methylprednisolone injection and systemic therapy for profound idiopathic sudden hearing loss (ISSNHL). METHODSTotal of 60 patients with ISSNHLwho had received therapy from June 2014 to May 2015 in Beijing Anzhen Hospital affiliated to Capital University of Medical Science,were randomly divided into 2 groups,the systemic application group (30 patients): dexamethasone (DEX) was applied intravenously in dose of 10 mg×5 d, and the postauricular injection group (30 patients): methylprednisolone sodium suecinate was injected subperiosteally near the upper one-thirds of postauricular sulcus every day, 40 mg×5 d.All 60 patients received the same medications for 2 weeks to improve the hearing. Hearing and tympanic membrane were monitered before the injections and two weeks after the termination of injections. SPSS 16.0 software was used to analyze the data.RESULTSThe postauricular injection group: 23 of 30 ears had improvement of hearing. No related complications were reported. The systemic application group: 23 of 31 ears had improvement of hearing (P>0.05) No related complications were reported.CONCLUSIONCombined postauricular methylprednisolone injection and systemic medications therapy can be considered as is an effective therapy for profound idiopathic sudden hearing loss. It can avoid the side-effects of high dose systemic corticostemid treatment. For ISSNHL patients, postauricular methylprednisolone injection may be an appropriate treatment.

It is very necessary to apply case-teaching method to Emergency Medicine in Universities of TCM. To establish the case-teaching system,we ourselves have written teaching materials,trained teachers, and designed all sorts of the medical records. Moreover, we have deployed other methods and principles to put this teaching into practice, used clinical skill practising as a essential supplement of teaching effect. Comparing with the traditional teaching method, it is clear that case-teaching method could make students' learning initiative and positivity improved significantly, their test scores promoted obviously. Thus, carrying out case-teaching method in Emergency Medicine could advance students capability of acquisition of knowledge and their clinical thinking .

Objective To investigate the risk factors and anticoagulation parameters in patients of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) combined with deep venous thrombosis (DVT). Methods All of 110 AECOPD patients were divided into two groups according to Doppler examination of lower extremities: DVT group and non-DVT group. The risk factors and anticoagulation parameters were compared. Results Twelve cases (10.9%) were in DVT group,of whom 2 cases (1.8%)had pulmonary embolism. The rate of lying in bed > 3 d, smoke, mechanical ventilation, hospital stays and the levels of PaCO2 were significantly higher in DVT group than those in non-DVT group (P < 0.01 or <0.05 ). In DVT group, the activity of antithrombin Ⅲ and the level of protein S decreased (P < 0.05 ), and the level of D-Dimer increased (P < 0.05). Conclusions Long-term bed, smoke and mechanical ventilation requirement are the main risk factors of DVT in patients with AECOPD. Respiratory failure (type Ⅱ ) is easier to combine with DVT. Abnormality of coagulation and fibrinolytic system exists in AECOPD with DVT.

OBJECTIVESTo evaluate the effect of surgical treatment on metastatic spinal tumor.

METHODSThe results of surgical intervention for metastatic spinal tumor of 31 consecutive patients since October 1985 were reviewed.

RESULTSThe average survival time was 17.6 months (range from 3 months to 9 years), and 4 patients are still alive with an average survival time of 24.6 months (range, 14 to approximately 84 months). No postoperative complication was noted. The preoperative symptoms were partially relieved and neurological functions were improved after surgery.

CONCLUSIONSurgical treatment for metastatic spinal tumor could improve the life quality, but should be adopted cautiously. The surgical procedures such as decompression and internal fixation should be involved only when neurological deficits occurred. The surgery with postoperative complementary therapy may not only improve the life quality, but also extend the patients' life span.

Objective:To investigate the effect and safety of rituximab, programmed death 1 (PD-1) monoclonal antibody, and Bruton tyrosine kinase (BTK) inhibitor on elderly refractory primary central nervous system lymphoma (PCNSL).Methods:The clinical data of an elderly patient with refractory PCNSL treated with the combination of rituximab, PD-1 monoclonal antibody and BTK inhibitor in the First Hospital of Jilin University in February 2020 were retrospectively analyzed. The relevant literature was reviewed.Results:The patient had primary central nervous system diffuse large B-cell lymphoma (high-risk group), and the Memorial Sloan Kettering Cancer Center (MSKCC) score was 2 (estimated overall survival time was 7 months). Disease progressed after 1 course of treatment. Complete remission was achieved after the therapy of rituximab, PD-1 monoclonal antibody combined with BTK inhibitor. PD-1 monoclonal antibody maintenance therapy was performed and patient was followed up until November 17, 2021. The patient's condition was stable. The second progression-free survival (PFS) time was 20 months, and the overall survival time was 21 months. The patient well tolerated the new drug treatment, and no adverse reactions of grade 3 or above occurred.Conclusions:The new targeted combination therapy can be used as a treatment option for elderly PCNSL patients, which can further improve the curative effect and significantly improve the prognosis.

The incidence of pediatric otomycosis is gradually increasing, with a widespread prevalence of multidrug-resistant Candida auris.However, its early diagnosis remains challenging, leading to misdiagnosis and underdiagnosis.This review aims to provide a comprehensive overview of pediatric otomycosis based on relevant domestic and international studies.This article reviewed the epidemiology, etiology, risk factors, pathogenic microorganisms, diagnosis, and treatment of pediatric otomycosis, aiming to enhance the understanding of pediatric otomycosis among healthcare professionals.
