ABSTRACT
Objective To carry out a meta-analysis on the published data to evaluate therapeutic effects of intact canal wall mastoidectomy and open mastoidectomy for cholesteatoma otitis media .Methods A comprehensive search was performed in VIP (1989-2015) ,WANFANG (1999-2015) ,CNKI (1994-2015) and CAJD databases to collect the randomized controlled trials (RCTs) on the intact canal wall mastoidectomy and open mastoidectomy treat cholesteatoma otitis media ,and to analyze the RCTs in meta -analysis method .Results 1 069 patients were analyzed in the 18 RCTs which met the inclusion criteria .Patients were followed up from 3 months to 7 years .The meta-analysis results suggested that ,compared with the open mastoidectomy group ,the patients had less operative time (test for overall effect :Z=15 .54 ,MD= -18 .36 ,95% CI(-24 .54 ,-12 .18) , P10 dB (test for overall effect:Z=2 .83 ,OR=2 .47 ,95% CI(1 .32 , 4 .61) ,P=0 .005) ,more patients with air-bone gaps <20 dB(Z=3 .05 ,OR=1 .60 ,95% CI(1 .18 ,2 .17) ,P=0 .002) ,but the recurrent rate is not different significantly (test for overall effect :Z= 1 .92 ,OR =1 .87 ,95% CI (0 .99 ,3 .53) ,P=0 .05) .Conclusion The illness is suitable to be treated by using the two surgical ways while the intact canal wall mastoidectomy treatment takes less operative time ,dry ear time and complications ,and improve hearing more significantly than the open mastoidectomy ,but the recurrent rate is not different significantly for trea‐ting cholesteatoma otitis media .
ABSTRACT
OBJECTIVE@#To analyze the forensic pathological characteristics of sudden death caused by pulmonary thromboembolism and the chronological transformation of thrombus and explore the assessment method of the causal relationship between previous trauma and the following fatal PTE episode.@*METHODS@#All the 23 cases reviewed here were collected from our institute files from the year of 1998 to 2008.@*RESULTS@#Trauma, surgery and braking etc. were all risky factors of PTE. Of these cases, 12 cases were caused by trauma, 21 cases were caused by surgery and 22 cases died in hospitals which were often happened one or two weeks after injury or one week's postoperative time. Of all the cases, 6 cases had single attack of thrombus and the rest 17 cases had the recurrence of thrombus. The number of the leg deep vein to be the embolic source was 16 cases which were often seen in the left leg.@*CONCLUSION@#It is important to confirm the embolic source, trauma, surgery and chronological events in determing the sudden death with PTE.

OBJECTIVE@#To analyze the pathological characteristics and the death reasons due to postpartum hemorrhage, and to help to deal with the obstetrical medical tangles.@*METHODS@#Thirty-two cases of death caused by postpartum hemorrhage encountered in our department since 1995 had been collected and retrospectively analyzed.@*RESULTS@#Death caused by postpartum hemorrhage could be divided into single factor and multi-factor, with 81.25% due to single factor, 12.50% multi-factor, and 6.25% unknown reason. The single factors included uterine atony, retained placenta, placenta increta, laceration of the lower genital tract, and coagulation defects. The multi-factor included a combination of two or more factors mentioned above.@*CONCLUSION@#The causes of death due to postpartum hemorrhage should be analyzed according to the clinical characteristics of the postpartum hemorrhage and the autopsy examination.

This study was to investigate the relationship between Clostridium difficile associated diarrhea (CDAD) and intestinal microecosystem in patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to clarify clinical characteristics of intestinal microecosystem disorder. Clostridium difficile (CD) was isolated and identified by enzyme-linked-immunosorbent assay using clostridium difficile Premier toxins A&B Kit and anaerobic culture in 44 cases with diarrhea. Fecal flora (bifidobacteria, lactobacillus, bacteroides, peptostreptococcus, Clostridium perfringens, enterobacteriaceae, enterococcus, and yeasts) of patients were quantitatively and qualitatively analyzed by Mitsuoka's methods. The results showed that CDAD occurred after using antibiotic or chemotherapy. Clostridium difficile was detected in 12 patients with diarrhea (positive rate was 27.27%). There was marked changes of intestinal microecosystem when patients suffered from CDAD. The number of lactobacillus, bifidobacteria, bacteroides, enterobacteriaceae and so on decreased significantly. It was effective to treat CDAD with vancomycin, metronidazole and probiotic, but the recurrence rate was 16.67%. In conclusion, CDAD complicated by allo-HSCT is related to change of intestinal microecosystem. While treating CDAD with the sensitive antibiotic, the intestinal flora of patients should be supported actively. This treatment contributes to improving disease status and reducing diarrhea recurrence.
