OBJECTIVETo evaluate the value of clinical signs in the identification of Mycoplasma pneumonia in children's community acquired pneumonia.
METHODWe searched the Cochrane library, PubMed, CNKI, Wan Fang and VIP databases. According to the inclusion and exclusion criterias, we selected and extracted the related information in the literature. According to the QUADAS evaluation system, we established the quality evaluation standard to evaluate the quality of the included studies and analyzed the difference of the clinical manifestations between Mycoplasmae pneumoniae and non-Mycoplasma pneumoniae in children's community acquired pneumonia. We used the RevMan 5.3 software to do the meta-analysis and collected the data according to the requirements. We calculated the pooled sensitivities, specificities and 95%CIs. Then we calculated the negative and positive likelihood ratio, the ratio of the diagnosis and the pre-/post-test probabilities with 95% CIs.
RESULTA total of 11 articles were included in the literature. In summary, the cases of the clinical signs of true positive (TP) and false positive (FP) were as follows : chest pain: TP: 287, FP: 1090; rales: TP: 1906, FP: 6886; headache: TP: 590, FP: 2051; pleural effusion: TP: 10, FP: 16; consolidation: TP: 75, FP: 83; emphysema: TP: 443, FP: 116. The pooled sensitivity, the pooled specificity, the diagnostic ratio (DOR) and 95% CI were: chest pain: pooled sensitivity: 0.12, 95% CI: 0.10-0.13, pooled specificity: 0.89, 95% CI: 0.88-0.90, DOR: 1.05, 95% CI: 0.92-1.21; rales: pooled sensitivity: 0.66, 95% CI: 0.64, 0.67, pooled specificity: 0.36, 95% CI: 0.35, 0.37, DOR: 1.12, 95% CI: 1.02, 1.22; headache: pooled sensitivity: 0.23, 95% CI: 0.21-0.25, pooled specificity: 0.80, 95%CI: 0.79-0.80, DOR: 1.16, 95%CI: 1.05-1.29; pleural effusion: pooled sensitivity: 0.04, 95% CI: 0.02, 0.08, pooled specificity: 0.98, 95% CI: 0.96, 0.99, DOR: 1.28, 95% CI: 0.56, 2.89; consolidation: pooled sensitivity: 0.32, 95% CI: 0.26, 0.39, pooled specificity: 0.87, 95% CI: 0.84, 0.90, DOR: 1.88, 95% CI: 1.23, 2.90; emphysema: pooled sensitivity: 0.22, 95% CI: 0.17, 0.29, pooled specificity: 0.73, 95% CI: 0.69, 0.77, DOR: 1.05, 95% CI: 0.68, 1.61.
CONCLUSIONThe value of clinical symptoms and signs in the identification of mycoplasma pneumonia in children's community acquired pneumonia was not significant. Although the clinical symptoms/signs of chest pain, headache, rales and chest X-ray manifestations of pleural effusion, consolidation, emphysema could suggest Mycoplasma pneumoniae infection, the presence or absence of any clinical signs were not positive or negative indicators for the identification of Mycoplasma pneumoniae infections.

Objective:To explore the feasibility, safety and short-term effect of the Hood technique in robotic-assisted radical prostatectomy (RARP).Methods:The data of 24 patients with localized prostate cancer underwent RARP with Hood technique From June 2020 to March 2021 were retrospectively reviewed. The mean age was 67.8 (57-76) years, and the mean body mass index was 25.17(18.31-32.54)kg/m 2. The mean tPSA value was 18.36(4.21-67.57)ng/ml and the mean biopsy Gleason score was 7.3 (6-8). In term of the clinical T stage, the 24 cases were composed of the T 1c stage in 1 case, T 2a stage in 5 cases, T 2b stage in 4 cases and T 2c stage in 14 cases. During Hood technique, the anterior bladder were limitedly isolated without exposing the outline of pelvis and prostate. Results:All the cases were completed robotically without conversion, transfusion or positive surgical margin. The average robot-assisted operation time was 84.5(63-110) mins. Estimated blood loss was 75.3(20-180) ml. The average time for maintaining the drain was 3.7(3-5) days. The mean postoperative hospital stay was 7.1(4-11) days. The mean catheterization time was 7.3(6-9) days after surgery. 23 patients achieved continence immediately after catheter removal, while 1 patient had continence full-recovery 2 weeks after surgery. The mean surgical Gleason score was 7.9 (6-9). In term of the surgical T stage, the 24 cases were composed of the pT 2a stage in 4 case, T 2b stage in 6 cases, T 2c stage in 14 cases.During 3-12 months’ follow-up, no biochemical recurrence was found. Conclusions:Hood technique were safe and valid in RARP with excellent immediate continence recovery. It facilitated Retzius sparing in a convenient approach with low positive surgical margin rate.
