Objective To analyse the effect of microwave therapy on tennis elbow. Methods 60 patients with tennis elbow during September, 2007 to September, 2008 were divided into treatment group and control group. The treatment received microwave therapy while control group was treated with Diclofenac Diethylamine. All patients were evaluated by Visual Analogue Scale (VAS) before and after the treatment.Results The VAS is lower in the treatment group than in the control group(P<0.01). Conclusion Microwave therapy is effective on tennis elbow.

OBJECTIVE Epithelial-myoepithelial carcinoma (EMC) is a rare malignant neoplasm of the salivary glands. The aim of the study was to investigate the diagnosis, treatment and prognosis of EMC of the parotid gland.METHODSThe clinical data of 23 cases of EMC of the parotid gland from 1999 to 2013 were analyzed retrospectively. Of all the patients, 13 cases received radical surgery only, 9 cases received postoperative radiotherapy, and one case received postoperative chemotherapy. Kaplan-Meier survival curve was used to analyze the clinical data. RESULTSThe overall survival rate at 5-year was 81.0% and the overall no recurrence survival rate at 5-year was 67.3%. The recurrence rate was 39.1% (9/23). The 5-year no recurrence survival rate of radical surgery group was 55.6%, compared with 80.0% in the combined modality therapy group, there was no significant deference (χ2=2.232, P=0.135).CONCLUSIONThe postoperative recurrence rate of EMC is high. Radical surgery could be the main treatment of EMC, when the surgical margin couldn't be achieved, adjuvant radiotherapy or chemotherapy might be helpful.

ObjectiveTo assess the cause of tadalafil failure and the feasibility of successfully rechallenging nonresponding patients.Methods A total of 80 consecutive erectile dysfunction ( ED ) patients who claimed poor response to tadalafil were enrolled into the study.A self-administered tadalafil-use questionnaire composed of eight questions was applied to assess how they had used tadalafil.Subjects were given thorough instruction based on individual answers and four doses of tadalafil 20mg.After a 2-week follow-up,end point efficacy of rechallenge was evaluated using the sexual encounter profile (SEP),which was recommended by international advisory panel in 2004.ResultsA total of 45 subjects had one or more areas of major suboptimal use of tadalafil:21.2％ did not know that sexual stimulation was necessary for tadalafil to work,87.5％ attempted to use tadalafil less than four times,57.5％ took a maximal dose less than 20 mg,and 84％ felt nervous or anxious.Of the 65 patients undergoing tadalafil rechallenge,30 patients answered “yes” to SEP2 and SEP3.The response rate to rechallenge was 46.2％ ( 30/65 ).ConclusionsInappropriate use of tadalafil was major cause of tadalafil non-pesponse.The efficacy of tadalafil could be improved to a better extent by education of patients.

Objective To compare the circumferential approach and suprapubic approach for correcting the concealed penis. Methods Thirty-four patients received circumferential approach (group A,18 cases)or suprapubic approach(group B,15 cases)randomly for the concealed penis.The length of penis without erection before and after surgery treatment,patients'satisfaction and surgical complications were evaluated.All the patients were followed at least 6 months after operation.Results The penile length before and after surgery in group A were(1.78±0.41)cm vs(3.97±0.47)cm,the length of the postoperative penis was significantly longer than that of the preoperative penis(P<0.01).83%of those in group A(15 cases)were satisfied with the cosmic results.The length of preoperative and postoperative penis in group B were(2.07±0.53)cm vs(4.05±0.81)cm respectively,the length of the postoperative penis was significantly longer(P<0.01).Satisfaction was 87%(13 cases).The postoperative penile length between the 2 groups was not different(P> 0.05).Prepuce edema was reported to Occur in 56%and 13%in group A and group B and spontaneously disappeared within 3 months.Fat synchysis occurred in 2 of group B. Conclusions The cosmic effect of the 2 surgical approaches is similar,but circumferential approach is simpler.There is no serious complication in those receiving circumferential approach.

Objective To evaluate the effects of different selection criteria on the prognosis of hepatocellular carcinoma(HCC)patients undergoing liver transplantation(LT)and to evaluate a new criterion.Methods A retrospective analysis was performed on 81 consecutive patients with HCC who underwent LT.The survival rates of the patients who met different criteria such as Milan.UCSF(University of California San Francisco UCSF).and Pittsburgh(Pitt)modified TNM criteria were calculated by KaplanMeier method,and the value of different criteria was evaluated.The Long-Rank test and COX proportional hazards regression model were performed to analyze the prognostic factors.the model of criteria was established according the most important prognostic factors.Using the Kaplan-Meier method,the suitable cut-offs of every variable ifl the model were found by comparing the survival and the number of the patients who met the cut-off,and considering the significant difference between the patients who met and exceed the cut-off at the same time.Resuits The 1,2,3-year accumulative survival rates of the 19 patients who met Milan criteria were 87.7%,87.7%,and 52.6%respectively:the 1,2,3-year disease free survival rates of them were 88.9%,72.7%,and 72.7%respectively.The 1,2.3-year accumulative survival rates of the 26 patients who met UCSF criteria were 87.2%,80.5%,and 55.2%respectively;the 1,2,3-year disease free survival rates of them were 84.1%,68.4%,and 68.4%respectively.With our new expanded criterion as of solitary tumor≤8 cm in diameter.or no more than 3 tumors,with the largest≤6 am,and a total tumor diameter≤10 cm.there was no significant difierence in 1,2,3-year sunrival rates and disease free survival rates(89.0%,81.8%,71.8%,and 81.9%,72.4%,72.4%.)as compared with Milan or UCSF criteria.but with this new criterion more patients(a=41)would be eligible for transplantation with a comparable long term survival.and the difference of the accumulative survival rates and disease free survival rates of the patients who met and exceed the new criteria was significant(P＜0.05).Conclusion The new indication is acceptable because the criteria does not adversely impact survival.

Objective To review the clinical manifestation,pathological characteristics,treat ment and prognosis of malignant mesothelioma of the tuniea vaginalis testis.Methods A case of ma lignant mesothelioma of the tunica vaginalis testis was reported and relative literature was reviewed.A34 year old man was admitted to hospital with a history of aggravated hydroeele for 5 years.A hardtumor was palpated above the right testis,which was smooth and slight tenderness.The level of β-hCG and AFP was normal.Ultrasonography revealed a 2.05 cm× 1.97 cm,well demarcated,mixedecho tumor.Results An operation was performed to incise the tumor and tunica vaginalis undersubarachnoid space block anesthesia.The tumor was histologically diagnosed as low potential malig nant mesothelioma of the tunica vaginalis testis.Microscopic examination showed that the tumor wasmalignant with a biphasic pattern composed of epithelial and stromal components.The former compo nent was dominant.The epithelial cells proliferated obviously with atypia and mitosis.Immunohisto chemical staining showed cytokeratin and vimentin were strongly positive.The capillary,lymph ves sel,spermatic cord and testis were not infiltrated.Right radical orchiectomy and right scrotectomywas performed one month after the first operation.There was no evidence of relapse during 38 monthfollow up after operation.Conclusions The major symptom of patients with malignant mesotheliomais hydrocele,malignant mesothelioma is diagnosed by histopathology.Due to the invasive potential ofthis disease and the risk of tumor recurrence,radical orchiectomy and close follow up are strongly rec ommended.

Objective To evaluate the efficacy of microvasoepididymostomy for the treatment of obstructive azoospermia. Methods Ninety-eight patients were confirmed as obstructive azoospermia by infertility investigations.The mean (range) age was 31 (20-43) years.The mean duration of obstruetion was 4 years.All patients were seen by the surgeon for a complete history and physical examination.Semen analyses proved azoopermia,serum levels of sexual hormone were normal and testicular function for production of sperms were normal certified by biopsy.All patients with suspected epididymal or vasal obstruction were offered scrotal exploration.The decision for microvasoepididymostomy was made during surgery,based on the pateney of the vas towards the abdomen documented by saline and sperm fragments containing in the epididymal fluid on intraoperative light-microscopic examination.Microvasoepididymostomy was performed in 58 patients documented epididymal obstruction The initial semen analysis was then done after usually 3 months postoperatively.Patency was arbitrarily defined as＞10 000 sperm/mL in ejaculate in at least one semen analysis after surgery.Postoperative patency rate and postoperative impregnation rate were followed. Results Fifty patients were followed up for 3-29 months,8 cases lost.Sperm was found by semen analysis in 36 patients.Sperm density was 4×104-2×108 sperms/ml and motility was 2%-70%.Semen analysis reveals azoospermia in 6 patients and the patients were counseled to undergo further testing to determine the ultimate outcome of the procedure.Natural conception occurred in 14 patients followed for more than 12 months.The overall pateney rate was 72%(36/50).Among patients with a follow-up of＞6 months,the natural paternity rate was 28%(14/50).The median time to achieve a natural pregnancy was 6.6 (4.0-10.0)months. Conclusion A more favourable patency can be achieved using microsurgical intussusception vasoepididymostomy and a part of patients with obstructive azoospermia can be cured by this means.

Objective To assess the causes of sildenafil failure and the feasibility of successfully rechallenging non-responding patients. Methods A total of 126 consecutive erectile dysfunction (ED) patients from Jan 2009 to Dec 2009 who claimed poor response to sildenafil (sildenafil 100 mg on demand, at lease 4 epiodes) were enrolled into the study. All patients received sexual reeducation and were treated with sildenafil, taken on a daily dose of 50 mg for 4 weeks. The International Index of Erectile Function-5 (IIEF-5), Rigiscan, serum testosterone or penile Doppler were used to evaluate ED and the cause of on-demand sildenafil failure. End point efficacy of rechallenging was evaluated using the IIEF-5 and the sexual encounter profile (SEP) 'Were you able to insert your penis into your partner's vagina?' and 'Did your erection last long enough to achieve successful intercourse?'. Results The recruited patients comprised of 41 cases with psychological ED, 39 cases with hypogonadism ED, 28 cases with diabetes mellitus ED and 18 cases with vascular ED. Compared with pretreatment and on-demand sildenafil baseline, daily administration of sildenafil significantly enhanced all efficacy outcome variables. The IIEF-5 was significantly improved after daily sildenafil (12.3 ± 2.9 vs18. 8±4.4, P＜0.01), 78 patients responded to daily sildenafil. The overall salvage rate was 61.9%(78/126). Conclusions Sexual reeducation and daily administration of sildenafil may be able to salvage many patients with ED who were sildenafil non-responders.

Objective To estabalish a new conception, Erectile Dysfunction-no sexual life (ED-NS), so as create an evaluating questionnaire, Self-estimation Index of erectile function-No sexual life (SIEF-NS) so as to investigate its clinical reliability. Methods The conception of ED-NS was identified and the SIEF-NS questionnaire was established. Patients who complained of ED-NS and normal controls were enrolled into the research and assessed the erectile function was assessed with SIEF-NS.The SIEF-NS includes 12 questions, such as sexual libido, general erectile function, nocturnal penile erection, erectile function during foreplay, erectile function during audio-video sexual stimulation,confidence, depression, etc and each question has 5 point scales. Results Sixty-one ED-NS patients and 57 controls were enrolled into the study and assessed erectile function with SIEF-NS. The mean score of each question and integral score of SIEF-NS in ED-NS patients were significantly different from normal controls (P＜0. 05). When the integral score was 35 points according to the ROC curve of integral score, the sensitivity of SIEF-NS was 88.5% and specificity was 96. 5%. Conclusions ED-NS is a new conception to define patients who have erectile dysfunction without sexual life. SIEFNS is suggested to be a useful method for the evaluation of ED-NS patients.

OBJECTIVE: To explore the clinical effects and short-term complications of using free jejunum graft (FJG) to reconstruct the defects by resections of pharyngeal, laryngeal or cervical esophageal cancers. METHOD: Fifty-eight cases of pharyngeal, laryngeal or cervical esophageal cancers were reconstructed with FJG. All cases were analyzed retrospectively. RESULT: The success rate of FJG transplantations was 91.4% (53/58). The incidence of post-operative short-term complication was 43.1% (25/58), which was not related to age or BMI. The most common complication was anastomotic leakage (18.9%), which was not related to per-operative radiation therapy. However, BMI > 25 cases had significantly higher incidence of anastomotic leakage than BMI ≤ 25 cases (P = 0.009). The second and third most common complications were respiratory system complications (10. 3%) and FJG necrosis (8. 6%). Para-operative death rate was 3.4% (2/58). Two-year overall survival rates of hypopharyngeal cancer and cervical esophageal cancer were 49% and 67% respectively. The group with no short-term complications had a slightly better survival rate than the group with short-term complications from the Kaplan-Meier curve, but there was no significant difference (P = 0.103). CONCLUSION FJG is ideal to reconstruct cervical digestive tract circumferential defects with a high success rate and a low mortality. However, the post-operative complication rate is high. Intensive observation, early detection and timely treatment of complications are crucial.
