Testicular torsion (TT) is a serious surgical emergency. Prompt diagnosis and treatment of TT are essential to improve the incidence of salvaged testes. The aim of this study was to evaluate the historical features, physical examination findings, laboratory tests, and ultrasound examinations in children with TT, as well as to identify the predictors of testicular salvage in children. Materials and Methods: We retrospectively reviewed the records of 136 males who presented with TT to our institution. Clinical findings, physical examinations, laboratory data, color Doppler ultrasound findings, operating results, and the results of followup were collected and analyzed. Patients with neonatal torsion, negative scrotal exploration, or testicular appendix torsion were excluded. A multivariable logistic regression model was used to identify predictors of testicular salvage. Receiver operator characteristics analyses were performed to determine the probability of a non-salvageable torsed testis based on time and degree of twisting. Results: A total of 136 children with TT were identified. Patients were aged from 1 to 16 years, with a mean age of 9.7 years (median, 12; range, 1-16 years). The peak incidences of TT were found between ages of 12 and 14 years. Acute TT is significantly more common in the winter. Testicular salvage occurred in 49 (36%) cases. Of the 49 cases of testicular salvage, 5 patients developed subsequent testicular atrophy. Cutoff values of 13.5 h and 530 degrees of torsion would provide sensitivities of 96 and 61%, with specificity of 80 and 70%, respectively. Multivariate analysis showed that time to surgery and degree of testicular twist were correlated with the risk of a non-salvageable testis. Conclusions: Testicular salvage can be predicted by the duration of symptoms along with degree of twisting. Early scrotal exploration based on careful physical examination decreases the risk of misdiagnosis of spermatic cord torsion. A certain percentage of children with TT presenting with lower abdominal pain should have their testicles checked to make sure that they do not have torsion, especially those visitors in cold season.
SO is a safe and effective surgical approach alternative to IO for pediatric UDTs. Compared with IO, SO has the advantage of shorter operative times. Besides, the incidence of postoperative wound infection may be slightly lower in SO. We suggest that SO should be considered as an acceptable option for children with UDTs.
Previous studies have raised interest in using the genotyping of CYP2C9 and VKORC1 to guide warfarin dosing. However, there is lack of solid evidence to prove that genotype plus clinical algorithm provides improved clinical outcomes than the single clinical algorithm. The results of recent reported clinical trials are paradoxical and needs to be systematically evaluated. In this study, we aim to assess whether genotype plus clinical algorithm of warfarin is superior to the single clinical algorithm through a meta-analysis of randomized controlled trials (RCTs). All relevant studies from PubMed and reference lists from Jan 1, 1995 to Jan 13, 2014 were extracted and screened. Eligible studies included randomized trials that compared clinical plus pharmacogenetic algorithms group to single clinical algorithm group using adult (≥ 18 years) patients with disease conditions that require warfarin use. We further used fix-effect models to calculate the mean difference or the risk ratios (RRs) and 95% CIs to analyze the extracted data. The statistical heterogeneity was calculated using I(2). The percentage of time within the therapeutic INR range was considered to be the primary clinical outcome. The initial search strategy identified 50 citations and 7 trials were eligible. These seven trials included 1,910 participants, including 960 patients who received genotype plus clinical algorithm of warfarin dosing and 950 patients who received clinical algorithm only. We discovered that the percentage of time within the therapeutic INR range of the genotype-guided group was improved compared with the standard group in the RCTs when the initial standard dose was fixed (95% CI 0.09-0.40; I(2) = 47.8%). However, for the studies using non-fixed initial doses, the genotype-guided group failed to exhibit statistically significant outcome compared to the standard group. No significant difference was observed in the incidences of adverse events (RR 0.94, 95% CI 0.84-1.04; I(2) = 0%, p = 0.647) and death rates (RR 1.36, 95% CI 0.46-4.05; I(2) = 10.4%, p = 0.328) between the two groups. Allocation to genotype plus clinical algorithm may be associated with a significant improvement of the percentage of time within the therapeutic INR range for patients adopting fixed dose of warfarin. The incidence of total adverse events and death rates did not differ between these two groups. Further experiments need to be conducted to confirm these findings.
This meta-analysis favors LH in the repair of bilateral hernias and for unilateral hernias in extraperitoneal approaches' group. Total postoperative complications were significantly reduced in LH, especially for major postoperative complications in male children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
