A 30-Month Complete Urinary Obstruction Resulting from Trapped and Incarcerated Uterus: A Case Report.
Uterine incarceration is rare, but it can caus e serious complications, in which the uterus is trapped in the pelvic cavity behind the sacral promontory. Fibroid uterus can cause urinary frequency and retention, which can result from compression of the urinary bladder with an enlarged fibroid uterus and the compression of the bladder neck or urethra, respectively. To our knowledge, there is no report on prolonged complete urinary obstruction because of an incarcerated uterus in nonpregnant women to date. ⋯ She immediately urinated immediately after the operation and had normal urination at 1- and 48-month follow-up visits. Uterine incarceration by a fibroid uterus can cause complete urinary obstruction, as in this case. Uterine incarceration should be considered in women with urinary frequency or retention to avoid prolonged, serious complications.

Background and Objectives: The treatment algorithm of lateral compression B2 type pelvic fractures are still under debate. Some authors advocate conservative treatment, while others recommend surgical approach. The clear indications for isolated anterior or posterior ring fixation or combined anterior-posterior pelvic ring fixation of B2 type fractures remain unclear. ⋯ No statistically significant differences were observed between the groups in both timepoints concerning Majeed, SF-36 PCS and MCS scores. However, in both groups Majeed and SF-36 PCS scores were statistically significantly lower one year after pelvic fracture compared with pre-trauma state, while SF-36 MCS scores did not differ. Conclusions: No differences were found in quality of life and functional outcomes between isolated posterior pelvic ring fixation and combined anterior-posterior fixation for the treatment of B2 type pelvic fractures.

Relative risk reduction and absolute risk reduction measures in the evaluation of clinical trial data are poorly understood by health professionals and the public. The absence of reported absolute risk reduction in COVID-19 vaccine clinical trials can lead to outcome reporting bias that affects the interpretation of vaccine efficacy. The present article uses clinical epidemiologic tools to critically appraise reports of efficacy in Pfzier/BioNTech and Moderna COVID-19 mRNA vaccine clinical trials. ⋯ For the Moderna vaccine mRNA-1273, the appraisal shows: relative risk reduction, 94.1%; 95% CI, 89.1% to 96.8%; p = 0.004; absolute risk reduction, 1.1%; 95% CI, 0.97% to 1.32%; p < 0.000. Unreported absolute risk reduction measures of 0.7% and 1.1% for the Pfzier/BioNTech and Moderna vaccines, respectively, are very much lower than the reported relative risk reduction measures. Reporting absolute risk reduction measures is essential to prevent outcome reporting bias in evaluation of COVID-19 vaccine efficacy.

Background and Objectives: This study aimed to observe the relationship between trace element concentrations in lung tissue from lung non-small cell lung carcinoma (NSCLC) patients and prognosis. Materials and Methods: The concentrations of various trace elements in the lung tissues were measured by a particle-induced X-ray emission (PIXE) system, and the results were analyzed for statistical significance. Eight essential trace elements, Cr, Mn, Fe, Co, Cu, Zn, Se, and Mo, were analyzed. ⋯ As for OS, Cr was the only element that showed a significant difference, and the high Cr element group had better OS (HR: 0.477, 95% CI = 0.128-0.97). Conclusions: This study suggests that the prognosis is good in lung cancer cases with high intratumoral concentrations of Co and Cr. The dynamics of trace elements in body and in tumor tissue have not been well established, and we consider that more research is necessary in the future.

Background and Objectives: Acute lateral patellar dislocation (LPD) is the most common acute knee disorder in children and adolescents, and may lead to functional disability. The purpose of this study was to identify key differences and correlations of the patellofemoral joint (PFJ) morphology between intact and contralateral injured knees in a first-time traumatic LPD population aged under 18 years. Materials and Methods: The data were gathered prospectively from a cohort of 58 patients (35 girls and 23 boys). ⋯ We noted statistically significant positive correlations (SSPCs) between the femoral sulcus angle (FSA) and PA in patients with intact (r = 0.37; p < 0.005) and contralateral injured knees (r = 0.33; p < 0.05). Conclusion: There were SSPCs between the FSA and PA in both gender and age groups of patients with intact and contralateral injured knees. The SSPCs between the FSA and PA of intact knees were higher in the patients with a more dysplastic PFJ anatomy (PA and TD) of the injured knees as compared to patients with only PA of the injured knees.
