[Clinical features of invasive candidiasis and risk factors for Candida bloodstream infection in children: a multicenter study in Urumqi, China].

OBJECTIVE: To investigate the clinical features of invasive candidiasis in children and the risk factors for Candida bloodstream infection. METHODS: A retrospective study was performed on 134 children with invasive candidiasis and hospitalized in 5 tertiary hospitals in Urumqi, China, between January 2010 and December 2015. The Candida species distribution was investigated. The clinical data were compared between the patients with and without Candida bloodstream infection. The risk factors for Candida bloodstream infection were investigated using multivariate logistic regression analysis. RESULTS: A total of 134 Candida strains were isolated from 134 children with invasive candidiasis, and non-albicans Candida (NAC) accounted for 53.0%. The incidence of invasive candidiasis in the PICU and other pediatric wards were 41.8% and 48.5% respectively. Sixty-eight patients (50.7%) had Candida bloodstream infection, and 45 patients (33.6%) had Candida urinary tract infection. There were significant differences in age, rate of use of broad-spectrum antibiotics, and incidence rates of chronic renal insufficiency, heart failure, urinary catheterization, and NAC infection between the patients with and without Candida bloodstream infection (P<0.05). The multivariate logistic regression analysis showed that younger age (1-24 months) (OR=6.027) and NAC infection (OR=1.020) were the independent risk factors for Candida bloodstream infection. CONCLUSIONS: The incidence of invasive candidiasis is similar between the PICU and other pediatric wards. NAC is the most common species of invasive candidiasis. Candida bloodstream infection is the most common invasive infection. Younger age (1-24 months) and NAC infection are the risk factors for Candida bloodstream infection.

Combination of improved sex therapy and sildenafil for erectile dysfunction in Uigur men: retrospective analysis of 2505 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>The sex therapy is not yet popularized at present. This study aimed to evaluate the effect of the combination of the improved sex therapy and oral sildenafil on erectile dysfunction (ED).</p><p><b>METHODS</b>A total of 3130 Uigur cases of ED received in Xinjiang Bogda Hospital were divided into a control group (n=625) and a trial group (n=2505), the former treated with oral sildenafil alone, and the latter by the combination of the improved genital therapy and sildenafil, both for 3 months and followed up at 6 and 12 months after the treatment. The therapeutic effects were evaluated and compared using IIEF-5.</p><p><b>RESULTS</b>The IIEF-5 scores of the control group were 12.80 +/- 3.76 and 18.10 +/- 2.61 before and after the treatment, and 17.35 +/- 2.73 and 16.64 +/- 2.63 at 6 and 12 months, respectively, while those of the trial group were 12.73 +/- 3.52 and 19.06 +/- 4.07 before and af- ter the treatment, and 19.86 +/- 2.42 and 20.47 +/- 2.38 at 6 and 12 months, respectively, with statistically significant differences either between pre- and post-treatment (P < 0.05) or between the control and trial groups at 6 and 12 months (P < 0.05).</p><p><b>CONCLUSION</b>The combination of the improved sex therapy and oral sildenafil is superior to sildenafil alone in the treatment of ED, and its efficacy is relatively stable at 12 months.</p>

One-stage radical eradication and wedged vertebral osteotomy through a purely posterior procedure in treating thoracic and lumbar spine tuberculosis associated with kyphosis or scoliokyphosis demormity / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility, clinical indications and significance of one-stage radical eradication, wedged vertebral osteotomy and instrumentation in the treatment of tuberculosis of thoracic and lumbar spine associated with kyphosis or scoliokyphosis through a purely posterior procedure.</p><p><b>METHODS</b>Sixteen cases with tuberculosis of thoracic and lumbar spine associated with kyphosis or scoliokyphosis were treated by one-stage radical eradication, wedged vertebral osteotomy and instrumentation fixation through posterior procedure. All patients included 12 males and 4 females, and the average age was 37.1 years (from 17 to 53 years). The preoperative average Cobb angle of kyphosis was 78.3 degrees (range from 54 degrees to 138 degrees ). There were 2 cases associated with scoliosis (the Cobb angle of scoliosis was 31 degrees and 24 degrees), and 1 case with lateral transition. Spinal cord compression were found in 7 cases. According to the Frankel's classification, 2 cases belonged to C degree, and 5 cases to D degree. There were 2 cases with caudal equina or nerve root lesions.</p><p><b>RESULTS</b>The average blood loss during the operation was 1100 ml (range from 450 to 2200 ml), and the average operation time was 265 min (range from 215 to 325 min). The postoperative results were satisfactory, 14 cases were excellent and 2 cases were good. Obvious improvement was obtained in 9 cases with neurological dysfunction. The postoperative average Cobb' angle was 28.5 degrees (range from 0 degrees to 67 degrees), and the corrective rate was 63.6%. The followed-up was ranged from 14 to 52 months with an average of 26.3 months. There were no major complications related to the fixations, loss of correction and the fusion were achieved in all patients.</p><p><b>CONCLUSIONS</b>One-stage radical eradication, wedged vertebral osteotomy and instrumentation is a feasible and an effective procedure in the treatment of spinal tuberculosis associated with kyphosis or scoliokyphosis. Compared with combined anterior and posterior procedure, the surgical technique may decrease injuries and has better result.</p>
