OBJECTIVE: To investigate the clinical feature, diagnose and therapeutic methods of paraglottic space primary paraganglioma. METHOD: One case of paraglottic space primary paraganglioma was reported and the relevant literatures were reviewed. RESULT: One case showed a hoarse voice, who was cured after the surgery of neck incision. NSE and CgA were positively expressed. CONCLUSION Paraganglioma of the paraglottic space is very rare. The diagnosis of paraglottic space primary paraganglioma bases on histopathology and immunohistochemistry. The immunohistochemistry and clinical character must be comprehensively analyzed to increase the diagnosis accuracy.

OBJECTIVE: To investigate the misdiagnosis cause of tuberculosis otitis media and mastoiditis. METHOD: The clinical data of 9 cases with tubercular otitis media and mastoiditis were analyzed respect. RESULT: Nine patients, only 1 patient in the preoperative tuberculosis in otitis media and mastoiditis, the remaining eight cases pre-operative misdiagnosed as chronic otitis media the pathologic diagnosis of tuberculous otitis media. CONCLUSION The clinical features of tubercular otitis media and mastoiditis was similar easily confused with chronic suppurative otitis media. Clinicians should pay attention to the disease, history of tuberculosis, imaging studies, and pathology, and other special examination to confirm the diagnosis, reduce misdiagnosed.

Purpose To investigate the relation of Epstein-Barr virus ( EBV) infections and malignant lymphoma. Methods EBV-co-ded RNA ( EBER) was detected by in situ hybridization in tumor tissue of 81 cases of malignant lymphoma in oral, maxillofacial and neck regions, with analysis of the clinical pathological features. Results The detection frequencies of EBER was 44. 44%. The posi-tive detection of EBER in Hodgkin′s lymphomas was 40% and that in non-Hodgkin lymphomas was 45. 1%, including 75% in T cell lymphomas, 87. 5% in NK/T cell lymphomas and 2. 9% in B-cell lymphoma. The positive rates of EBER in T cell lymphomas and NK/T cell lymphomas were significantly higher than that in B-cell lymphoma (P<0. 05). There was a significant difference in the pos-itive rates of EBER between intra-nodal ( 17. 9%) and extra-nodal ( 58. 5%) lymphomas ( P<0. 05 ) . But there was no significant difference the positive rates of EBER between in lymphoma patients over 50 years of age and under the age of 50 patients (55. 9%) (P>0. 05). Conclusion Oral and maxillofacial and neck lymphoma is closely associated with EBV infection in Guangxi region, espe-cially, in which NK/T cell lymphoma most typically occurs in extra-nodal diffuse lymphoid tissues.

Objective To understand the distribution of inhaled allergens throughout Hainan province and explore effective preventive measures against allergen by examining the serum allergen of patients with chronic rhinosinusitis (CRS), which will provide evidence for specific immunotherapy for treating CRS. Methods Three hundred and eighteen CRS patients underwent Phadiatop blood test by using the UniCAP 100 , a completely automatic autoanalyser. Allergen-specific IgE of 7 common allergens were tested and the concentration of total immunoglobulin E (TIgE) was collected and evaluated. Results The positive rates of the serum TIgE and inhaled allergens were 64.15% and 37.74% respectively. The incidences of the positive serum SIgE is 33.96%. Among the positive cases, 28.30% of the inhaled allergens were dermatophagoides pteronyssinus, 27.36% for tropical mites, 21.07% for dermatophagoides farinae, 13.52% for cockroach, 11. 64% for house dust, 7. 86% for cat dander and 0.63% for dog dander. The incidences of positive TIgE and SIgE were not significantly different between patients with nasal polyps and sinusitis only. Conclusions Dermatophagoides pteronyssinus, tropical mites and dermatophagoides farinae are the main inhaled allergens for CRS patients in Hainan.

OBJECTIVE: To investigate the clinical manifestation, pathological characteristics, treatment and prognosis of dendritic cell tumor. METHOD: Four cases of nasal and pharyngeal dendritic cell tumor were described, including two cases of follicular dendritic cell sarcoma (FDCS), one case of Langerhans cell histiocytosis (LCH) and one case of Langer hans cell sarcoma (LCS). One of the patients with FDCS received multimodality therapy (surgery combined with chemotherapy), and the other patient only received chemotherapy and radiotherapy. The patients with LCH or LSC were treated by surgery. RESULT: Of the two FDCS patients, one achieved complete remission after treatment by surgery combined with four cycles of CHOP chemotherapy regimen and concurrent radiotherapy (50 Gy), and the other who only received chemotherapy and radiotherapy survived with tumor for more than seven months of follow up. The patient of LCH was followed up for more than 2 years after surgery without recurrence or metastasis. The patient of LCS did not undergo radiotherapy or chemotherapy after surgery and died after 10 months of follow up. CONCLUSION Dendritic cell tumor is a group of very rare tumor and can be easily misdiagnosed in clinic, the confirmed diagnosis of which relies on histopathological features, immunohistochemistry combined with electron microscopy. FDCS, LCH and LCS have different pathological features, immunophenotypes and prognosis.

Objective:To systematically review the teaching effect of problem-based learning (PBL) combined with evidence-based medicine (EBM) teaching mode on the standardized residency training.Methods:CNKI, Wanfang database, VIP database, SinoMed, Embase, PubMed and Web of SCI databases were searched, and the randomized controlled trial (RCT) studies of the application of EBM combined with PBL teaching in standardized residency training were collected. The retrieval time was from the establishment to 1st July, 2018. Two investigators independently extracted data and assessed the quality of the studies. After assessing the risk of bias of included studies, Meta-analysis was performed on RevMan 5.3.Results:In total, 4 studies were included in the review. Narrative assessment was adopted, because outcome indicators of these study were varied and the quality of the literatures could not meet the requirement of Meta-analysis. Our study suggested that the residents who were in PBL combined with EBM teaching mode group got higher scores in the standardized residency training, compared with those in the lecture-based learning (LBL) teaching mode group, especially in case analysis score, total score of examination, improvement of clinical thinking ability, communication and expression ability, organization and cooperation ability, etc.Conclusion:The current evidence suggests that the application of EBM combined with PBL teaching mode has a positive effect on the standardized residency training. Compared with the traditional LBL teaching, EBM can improve students' ability. However, limited by the quantity and quality of included studies, the above conclusions still need to be verified by more studies with larger samples and higher quality.
