The clinical significance of 1,3-beta-D glucanase detection in plasma to the diagnosis of fungal rhinosinusitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the clinical significance of 1,3-beta-D glucanase detection in plasma to the diagnosis of fungal rhinosinusitis.@*METHOD@#MB-80 rapid microorganism detection system was used to detect preoperative and postoperative 1,3-beta-D glucanase in plasma of 37 patients of fungal rhinosinusitis which were treated by endoscopic sinus surgery and confirmed by postoperative pathology. Blood samples of 47 patients who underwent endoscopic surgery(fungal rhinosinusitis excluded) were taken as control group.@*RESULT@#1,3-beta-D glucanase content is more than 10 pg/ml in 34 cases of the fungal rhinosinusitis group,and every 1,3-beta-D glucanase content of 47 control cases is less than 10 pg/ml. Significant difference is found between case and control groups(chi2 = 72.6, P < 0.01).@*CONCLUSION@#1,3-beta-D glucanase detection in plasma is a simple,rapid diagnostic method of fungal rhinosinusitis.

Clinical analysis of the difficult postoperative decannulation resulting from tracheotomy between children and adults / 中国小儿急救医学

Objective To investigate the causes,diagnosis,treatment of the difficult postoperative decannulation resulting from tracheotomy between children and adults and the method of improving the rate of successful decannulation.Methods Clinical data of 56 cases with difficult decannulation after tracheotomy were analysed retrospectively,all the patients were admitted in our hospital between Jan 1990 and Oct 2006.All the patients were separated into two groups,children group including 24 cases of 14 months ～ 14 years old,adult group including 32 cases of age ranging 15 ～ 48 years old.The postoperative time after tracheotomy were 6 month ～ 1.5 year and 6 month ～ 2 year respectively.Results There were differences of the etiology,diagnostic choice and the clinical manifestation in the treatment of the diffficult decannulation after tracheotomy between children and adults.Children with difficult decannulation after tracheotomy occurred mainly in laryngitis and airway foreign body airway caused by obstruction retrieved after tracheotomy (14/24,58.33 ％),followed by the emergency tracheotomy,such as head and neck trauma (7/24,29.17％).Adults with difficult decannulation after tracheotomy mainly occurred in the throat caused by traumatic lesions of the larynx (including malformations,subglottic stenosis of larynx or vocal cord paralysis) (23/32,71.88％).The average block time in children with anti-inflammatory treatment was significantly lower than that in without anti-inflammatory therapy (6.2 d vs 10.1 d,t =4.26,P ＜ 0.01).However,there was no significant difference in the average block time in adults with anti-inflammatory and without anti-inflammatory treatment (t =1.63,P ＞ 0.05).In the course of treatment,rates of children consciously breathing difficulties (21/21,100％) was also significantly higher than the adult group (13/28,46.43％).Conclusion Children less than 3 years old should avoid tracheotomy.There is no definite relation between the successful treatment in the difficult decannulation and the age of the patients over 3 years old.The first failure treatment in children may be related with the local inflammation.When in treatment,doctors should observe the characteristics of respiratory difficulties,take attention to the influence of children psychological factors to the treatment.Children should be treated in the non-traumatic examination methods.

Clinicopathologic features of respiratory epithelial adenomatoid hamartoma of bilateral olfactory clefts / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To describe five rare cases of bilateral olfactory clefts respiratory epithelial adenomatoid hamartoma (REAH), and investigate the clinicopathologic features in REAH.@*METHOD@#Five cases with REAH were reported and the relevant literatures were reviewed. All the cases were confirmed by pathology.@*RESULT@#The chief complaint in 4 cases when visited was nasal obstruction and rhinorrhea, with or without hyposmia and headache. Another was discomfortable of head-facial region, sometimes with pus discharge and blood in nasal discharge. Polypoid neoplasms can be seen in nasal meatus of the 5 cases. Endoscopic sinus surgery was utilized to eliminate foci in 5 cases. All REAH foci located in bilateral olfactory clefts areas, four of which appeared polypoid changes,one appeared obvious inflammatory edema. All of them presented as wide-based lesion with tenacious quality compared to polyps. Histologically, these lesions were characterized by a glandular proliferation lined by ciliated respiratory epithelium originated from the surface epithelium, and the glands surround into round or oval, with various sizes and separated by stromal tissue.@*CONCLUSION@#It is possible to continue developing after operation, if REAH is not completely resected. Complete resection of lesions is the key to treatment success for this entity in endoscopic sinus surgery. Although REAH arising from the rhino sinusal region is very rare, rhinolaryngologists must know this entity in order to differentiate it from inverted papilloma and adenocarcinoma.
