RESUMO
OBJECTIVE@#This study conduct a qualitative synthesis and quantitative meta-analysis of VFAFI, aimed to study whether it is a useful treatment for UVCP.@*METHOD@#Electronic databases PubMed, YZ365. COM, WANFANG DATA, CMJD, CHKD,CNKI were searched using relevant keywords. Reported treatment outcomes were clustered into three categories,i. e. subjective, perceptual,acoustic,aerodynamic,and stroboscopic. Meta-analyses were performed on studies with numerical results using random effects model.@*RESULT@#Five articles were identified with a total of 404 patients. All the studies reported significant improvements or decrease after VFAFI in each category of outcome measurements. Meta-analysis demonstrated a significant increase or decrease in all categories. Adverse effects include slight inflammatory reponse can resolve spontaneously within 1 month. The recurrence rate after VFAFI was high due to the self absorption. NNE and Jitter of post-operation is lower than pre-operation,there is no significantly change between the control group and experimental group; F0, Shimmer and MPT of post-operation is higher than pre-operation, there is no significantly change between the control group and experimental group.@*CONCLUSION@#The invasiveness and morbidity of VFAFI are low and the side effects are self-limited. Meta-analyses demonstrated significant improvements or decreased from both objective and subjective measurements. Further controlled studies with longer follow-up periods and more person were included may evaluate the effectiveness of VFAFI more reliably.

We assessed the accuracy of a wrist-worn device WatchPAT 200 for the diagnosis of obstructive sleep apnea (OSA) and sleep and wakefulness indicators compared to standard polysomnography (PSG) using American Academy of Sleep Medicine (AASM) criteria. Twenty-eight adults with suspected OSA underwent a standard in-hospital PSG while wearing a WatchPAT 200. PSG events were manually scored using AASM criteria; WatchPAT 200 data were collected and analyzed by an automatic algorithm. The accuracy of WatchPAT 200 algorithm in apnea hypopnea index (AHI) and sleep-wake detection was compared to standard PSG methodology. The study population consisted of 21 males and 7 females, mean age of 47.45 ± 13.46 years, and mean body mass index of 29.99 ± 5.74 kg/m(2). For AHI, the mean PSG score for events per hour was 23.00 ± 21.55 compared to a mean score of 25.99 ± 19.09 for WatchPAT (r = 0.92, P < 0.001). The agreement of the sleep-wake assessment based on 30-s bins between the PSG and the WatchPAT was 89 ± 6 %. WatchPAT 200 detected OSA based on AHI with comparable accuracy, and provided a reasonably accurate estimation of sleep and wakefulness in patients with OSA on an epoch-by-epoch basis.

OBJECTIVE@#To observe the exposure of the vocal lesions under endoscopes of different angles and to contrast the endoscopes' influence on surgery.@*METHOD@#Fifty patients with benign vocal lesions were selected randomly. During microlaryngoscopic surgery, the laryngoscope was placed softly and the different rigid endoscope (30 degrees, 45 degrees or 70 degrees) was connected to video system to expose the glottis and vocal folds. The operation was taken through looking at the color monitor.@*RESULT@#The vocal fold lesions were completely examined and successfully excised in all patients, only two of them got soft palate mucosal abrasion. No one got complications.@*CONCLUSION@#Rigid endoscopy associated with microlaryngeal surgery brings a better observation to the vocal lesions and a lower incidence rate of complicatons. It's regarded that 45 degrees rigid endoscope is better than the others, for it provides not only a good exposure to the vocal cords, anterior commissure and subglottis, but also convenience to operate. The second one is 30 degrees rigid endoscope, which can save the cost, because of the widely using in many other departments.

Objective To investigate the phenotype and genetic characteristics of a Chinese family with an autosomal-dominant inherited sensorineural hearing loss.Methods A Chinese pedigree associated with an autosomal-dominant inherited low-frequency sensorineural hearing loss (LFSNHL) was investigated.After obtaining informed consent from all study participants medical and audiological examination were used to rule out any syndromic hearing impairment.Five patients were tested with DPOAE and ABR,while two patients were tested with vestibular function and computed tomography scan of the temporal bone to exclude auditory neuropathy and other possible aural disorders.Twenty-one loci and twenty-three genes of DFNA screening had been done by using microsatellite markers and linkage analysis.Results Proband of the family had been diagnosed with low-frequency sensorineural hearing loss.A Chinese family BJ-L046 with non-syndromic autosomal dominant hearing loss was ascertained.Hearing impairment in the affected members in family BJ-L046 occured from 10 to 20 years of age and mainly affected the low frequencies,causing an upsloping audiogram.Higher frequencies were getting involved with increasing age,thus causing a flat-type audiogram.No positive result was found in twenty-one loci and twenty-three genes of DFNA screening.Conclusion A Chinese family with late-onset low-frequency sensorineural hearing loss was clinically studied.No positive result was found by linkage analysis,and twenty-one loci and twenty-three genes of DFNA were preliminary excluded.
RESUMO
OBJECTIVE@#To evaluate the clinical effectiveness of injection n-Butyl cyanoacrylate (NBCA) in treating laryngopharynx hemangioma.@*METHOD@#Thirty cases of laryngopharynx hemangioma who received NBCA injection were obtained from our department 1998-2007. Twenty-five cases had tracheotomy under General anesthesia, and NBCA was injected into hemangioma by direct laryngoscopy. NBCA was mixed with iodide, and the concentration was 25.00% to 33.33%, NBCA dosage was 0.5 ml to 2.0 ml. There were 5 cases whose hemangioma confined to oropharynx didn't have tracheotomy, and they were injected straightly with the speculum oris. We observed the shedding of hemangioma in different time.@*RESULT@#Hemangioma with diameter less than 1 cm, shedded in about 1 month. However, hemangioma with diameter more than 4 cm, shedded in a period more than 3.5 month. No recurrence was observed in the follow up of 3 months to seven years.@*CONCLUSION@#Avoiding dissection of neck and repetitious operation, NBCA injection could be a safe, simple and effective therapy for laryngopharynx hemangioma.

Objective To investigate the efficacy and safety of hydrogel soft contact lens(HSCL) for persistence corneal epitheliopathy after intraocular surgery.Design Retrospective case series.Participants 36 patients(36 eyes) with bullous keratopathy(n=5) or other keratopathy(n=31) including corneal erosion,epithelium missing,and dendritic keratopathy after intraocular surgery,which failed to medicine treatment 2 weeks ago.Method All patients were fitted with HSCL after suitable processing of the corneal foci.The lenses were removed immediately as long as the keratopathy recovered.A new lens was replaced after 3 weeks if still needed.Main Outcome Measures Changes of keratopathy,pain relief and complications.Result 35 patients(97.22%) fitted with HSCL were very comfort within 3 days.At the follow-up of 6 months,30 patients(83.33%) achieved complete remission of keratopathy,6 patients (16.67%) remarkable remission.30 patients(86.11%) had vision increase.All of the non-bullous keratopathy recovered within 3 weeks,while the lenses were fitted much longer in bullous keratopathy.No other lens-related complications appeared.Conclusion The application of hydrogel soft contact lens to persistence corneal epitheliopathy after intraocular surgery is safe,effective,and practical.
RESUMO
Objective To analyze the mutations of candidate WFS1 gene in the Chinese pedigree with Low frequency sensorineural hearing loss. Methods PCR were performed with fourteen pairs of primers in the coding sequence of WFS1 gene. The PCR products were subsequently sequenced in the 38 individuals of LFSNHL family for screening the gene mutations. Results The PCR amplification fragments showed well quality in the five pairs of primer, and further analysis with frequencing showed no polymorphism and mutations in the members. Conclusion The present study rule out the possibility that the deafness gene WFS1, which locates on the 4p16, lead up to the hearing loss of LFSNHL pedigree.
RESUMO
Objective To evaluate the clinical manifestations, pathological features, diagnosis, differential diagnosis and treatment of extranodal Rosai Dorfman disease(RDD) in paranasal sinuses. Methods The clinical manifestations, pathological findings, and imaging data of a rare case of extranodal RDD in the paranasal sinuses, who had received repeated surgical interventions, were analyzed. Results The lesion was situated in the paranasal sinuses, It had been repeatedly removed and misdiagnosed. Physical examination showed a red spherical mass in the nasal cavity. CT scan of the sinuses revealed a 5cm 5 cm soft tissue opacification of the right nasal cavity and paranasal sinuses. There was also erosion of the lateral wall of the maxillary sinus, the medial wall of orbit, parts of pterygopalatine fossa, and infratemporal fossa. Through the previous incision, all visible tumours in the lateral nasal cavity, paranasal sinuses, pterygopalatine fossa and orbital base were again removed. The tumour was attached to the orbital periosteum. The orbit was not removed, but the tumour was stripped off as completely as possible. Microscopic examination revealed intermingling spindled shaped and polygonal histiocytes, admixing with few plasma cells. The infiltrating histiocytes had large round or oval nuclei. The cytoplasm was abundant, granular or vacuolated and foamy. Immunohistochemical studies showed that the histiocytes were strongly reactive with antibodies against S100 protein and Vimetin. Conclusion The diagnosis of extranodal RDD in the paranasal sinuses should be differentiated with rhinoscleroma, eosinophilic granuloma, plasmacytoma, or fibrous histiocytoma. The identification of the distinctive histocytes which are typically immunoreactive to S 100 and CD68 can be quite helpful for correct diagnosis. Surgical excision supplemented by chemotherapy and radiotherapy, may be the optimal treatment, and long term follow up is essential.
RESUMO
Objective The objective of this experiment was to find out the causes and mechanisms of vocal cord granulomas,to analyze the results of different treatments and to establish an effective protocol of treatment.Methods 24 patients with vocal cord granulomas were analyzed in terms of genders,ages,occupations,etiologies,such as voicing,gastroesophageal reflux,and treatment under general anesthesia and jet-ventilation,treatments and outcomes.Results Based on different etiologies,patients were divided into 4 groups: Group I of 9 patients with pathologic phonation,Group II of 8 patients with gastroesophageal reflux,Group III of 2 patients with treatment under general anesthesia and jet-ventilation,Group IV of 5 patients with unknown causes.9 patients received operations while 8 demonstrated good prognosis and one was completely cured.The vocal cord granulomas for 11 patients disappeared,8 had reduced vocal cord granulomas,and the vocal cord granulomas for 5 patients without any treatment were gone 6 months later.Conclusion The vocal cord granulomas can be caused by many factors with gastroesophageal reflux as a main etiology.Higher recurrences were noted after surgical treatment;therefore,treatment for gastroesophageal reflux and voice therapy should be considered as major approaches.
RESUMO
A consecutive series of 37 eyes of 34 glaucoma patients treated by transillumination guided cyclocryo- therapy(CCT)either to obtain pain relief or to achieve IOP control in Helsinki University Eye Hos- pital was studied.The follow-up range was 1~43 months(mean 9 months).Pretreatment IOP was 38?14mm Hg and postoperative 27?17mm Hg(mean ?SD).Twenty-four eyes underwent one and 13 eves 2~5 procedures.IOP control(IOP 9~24mm Hg) was achieved in 51%.The response was more favo- rable in eyes without iris neovascularization(62% achieved lOP control)than in eyes with neovascular glaucoma(38% achieved IOP control).The best response was achieved in eyes with chronic uveitis (6/7 of eyes achieved lOP coutrol).Repeated proce- dures improved IOP control rate.Thirteen eyes needed primarily pain relief and 85% achieved it.Postope- rative vision was unchanged in 30% and became worse in 54%.Transillumination guided the applica- tion of the cryoprobe to the correct site.Hypotony (IOP
RESUMO
Six human epikeratophakia lenticules were remo- ved 1 to 23 months after refractive keratoplasty for aphakia(2)and myopia(3).The myopic group in- cluded one epi-lens treated with ArF-excimer laser for hyperopia.Causes of removal were epithelial de- fect(4),edema of host cornea(1)and overcorre- ction(1),The epi-lens stroma showed a central regular fibrillar structure with a low keratocyte den- sity.Electronmicroscopy revealed preserved cytoplas- mic organelles and nuclear appearance.Lymphocytes and other mono-nuclear cells were absent,Bowan's membrane was normal in all cases.Breaks were not seen while a slight wavy appearance and occasionally focal bends occurred.The epithelium was somewhat irregular and changing in thickness.In the peripher- al wound region stromal and epithelial irregularities were evident.

RESUMO
By means of radioimmunoassay, leucine-enkephalin (L-ENK) in the uteri of women and rats was studied and its responses to ovarian steroids were observed. The histological localization of L-ENK and the influence of naloxone (NAL) on estrogen regulation of the rat uterus in terms of cAMP and eGMP determination were also studied. Results of the study demonstrated that presence of L-ENK like substance in the uteri of women and rats, and the concentrations varied in the various phases of the sexual cycle. indicating a positive correlation with levels of estrogen in the body. L-ENK was found localized in the interstetial cells of the human endometrium, and in the rat uterus. Effect of extrogen on nucleotide was influenced by NAL. The findings suggested that L-ENK may play an important role on physiologic function of utetus.
