Leiomyoma is a benign smooth muscle tumor which is rarely found in urethra. We hereby report a case of a 44-year-old female who presented with complaints of dysuria. ⋯ Urethral leiomyoma is a rare benign tumor that is often misdiagnosed in clinical practice. Diagnosis requires careful clinical examination. Surgical removal usually works well. It is important to remember that in some cases of acute urinary retention, it can be caused by a complete obstruction of a mass in the urethra. Urologists should be more cautious and experienced in handling such cases.

Case Reports
Case of acute retinal necrosis with rapid progression to proliferative vitreoretinopathy: A case report.
Acute retinal necrosis (ARN) was first reported in 1971 by Urayama et al as an acute uveitis accompanied by retinal arteritis and white retinal lesions in the peripheral retina that can progress to a rhegmatogenous retinal detachment (RRD). We have experienced a case of ARN that, unlike the common developmental course to an RRD associated with ARN, progressed to proliferative vitreoretinopathy (PVR) involving the entire retina in 2 days. The purpose of this report is to present our findings in the case of ARN with an atypical rapid time course. ⋯ Our findings of a case of ARN showed that the progression from a local vitreous traction to a full circumferential PVR can develop in 2 days.

Observational Study
Impact of perinatal factors on meconium aspiration syndrome in full-term newborns and the construction of a column chart prediction model: An observational study.
To explore the influence of perinatal-related factors on meconium aspiration syndrome (MAS) in full-term neonates and construct a nomogram prediction model for risk stratification of neonatal MAS and adoption of preventive measures. A total of 424 newborns and their mothers who were regularly examined at our hospital between January 2020 and December 2023 who had meconium-contaminated amniotic fluid during delivery were retrospectively selected as participants. Neonates were divided into MAS and non-MAS groups based on whether MAS occurred within 3 days after birth. ⋯ The model was also tested for goodness-of-fit deviation (χ2 = 3.465, P = .903). Decision curve analysis found that the model was clinically effective in predicting the net benefit of MAS risk in neonates with meconium-stained amniotic fluid. The construction of a column chart prediction model for neonatal MAS risk based on prenatal amniotic fluid index, gestational age, delivery method, amniotic fluid contamination level, newborn umbilical blood pH value, and Apgar 1-min score has a certain application value.

Bilateral vestibulopathy is an important cause of imbalance. There are multiple etiologies of bilateral vestibulopathy (BVP), but reports of BVP due to otosyphilis are rare. ⋯ Bilateral vestibulopathy should be considered when evaluating patients with acute or subacute persistent dizziness. Clinicians should also be aware of the potential for otosyphilis among patients who report BVP.

The aim of this study was to compare the biomechanical performance of pedicle screw construction and locking compression plate fixation in posterior pelvic ring injuries analyzed by finite element method. ⋯ The study suggested that the pedicle screw construction could provide better fixation stability than the locking compression plate and serves as the recommended fixation method for the treatment of posterior pelvic ring injuries.
