Here we report a rare case that a bamboo stick accidentally pierced into the left chest of a young man who was drunk and unware of this hurt. The patient experienced cough, chest pain, fever, hemoptysis, and was misdiagnosed as primary and secondary tuberculosis based on chest CT examinations at a local hospital, although no tubercular bacillus detected by sputum smear. He subsequently received anti-tuberculous treatments in the following three years, but no improvement of his symptoms was observed. Until one month before his death, the bamboo stick was detected by spiral CT examination as well as three-dimensional image reconstruction at another hospital. Postmortem examination revealed pneumonia, pulmonary infarction, and abscess as the causes of his death. We analyze the potential reasons of misdiagnosis in this case, aiming to provide reference for the diagnosis and treatment of pulmonary inflammation associated with foreign body in the future.</p>","PeriodicalId":10186,"journal":{"name":"Chinese medical sciences journal = Chung-kuo i hsueh k'o hsueh tsa chih","volume":"36 3","pages":"252-256"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39531606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The evaluation method recommended by Cochrane Collaboration for bias risk assessment was employed for quality assessment. Random or fixed models were used to investigate pooled mean differences in left ventricular function, serum glucose metabolism, serum lipid profile, myocardial ischemia episodes and exercise tolerance with effect size indicated by the 95% confidence interval (<i>CI</i>).Results Additional TMZ treatment contributed to considerable improvement of left ventricular ejection fraction (<i>WMD</i>=4.39, 95%<i>CI</i>: 3.83, 4.95, <i>P</i><0.00001), left ventricular end diastolic diameter (<i>WMD</i>=-3.17, 95%<i>CI</i>: -4.90, -1.44, <i>P</i>=0.0003) and left ventricular end systolic diameter (<i>WMD</i>=-4.69, 95%<i>CI</i>: -8.66, -0.72, <i>P</i>=0.02).

To bridge the knowledge gap, we did a meta-analysis to assess the efficacy of ≤6 months versus ≥12 months DAPT among patients with second-generation drug-eluting stents.Methods We searched online databases and identified randomized controlled trials that assess the clinical impact of short-term DAPT (≤6 months) published before March 3, 2016. The efficacy endpoints included the incidence of all-cause death, myocardial infarction, cerebrovascular accidents, and definite or probable stent thrombosis. Safety endpoint defined as major bleeding was also evaluated and discussed.Results We included 5 trials that randomized 9473 participants (49.8%, short-term DAPT duration vs. 50.2%, standard duration). A total of 9445 (99.7%) patients reported the efficacy endpoints, and the safety endpoint was available from 4 studies (n=8457). There was no significant difference in efficacy endpoints between short-term and standard DAPT duration (≥12 months) [risk ratio (RR) 0.96; 95% confidence intervals (CI), 0.80-1.15]. Short-term DAPT duration did not significantly increase the individual risk of all-cause death, myocardial infarction, cerebrovascular accidents, or definite or probable stent thrombosis. Although short-term DAPT obviously reduced risk of major bleeding compared with standard DAPT (RR 0.53; 95% CI, 0.29-0.96), significant publication bias was found when accessing the safety endpoint of the 4 studies (Egger's test, P=0.009).Conclusions The efficacy of short-term DAPT was comparable with that of standard duration DAPT.
