To prevent fetal loss, preterm delivery, and perinatal morbidity of multifetal pregnancies (MPs), fetal reduction (FR) is offered to some patients. We retrospectively analysed the data of 124 MPs that underwent transabdominal FR to twin (

A multimodal analgesic method was known to avoid the high-dose requirements and dose-dependent adverse events of opioids, and to achieve synergistic effects. The purpose of this study was to compare the efficacy of our multimodal analgesia (MMA) regimen with that of the patient-controlled analgesia (PCA) method for acute postoperative pain management. Patients who underwent one or two-level posterior lumbar fusion (PLF) followed by either MMA or PCA administration at our hospital were compared for pain score, additional opioid and non-opioid consumption, side effects, length of hospital stay, cost of pain control, and patient satisfaction. From 2016 through 2017, a total 146 of patients were screened. After propensity score matching, 66 remained in the PCA and 34 in the MMA group. Compared with the PCA group, the MMA group had a shorter length of hospital stay (median (interquartile range): 7 days (5&ndash, 8) vs. 8 (7&ndash, 11), P = 0.001) and lower cost of pain control (70.6 &plusmn, 0.9 USD vs. 173.4 &plusmn, 3.3, P &lt, 0.001). Baseline data, clinical characteristics, pain score, additional non-opioid consumption, side effects, and patient subjective satisfaction score were similar between the two groups. The MMA seems to be a good alternative to the PCA after one or two-level PLF.

Methicillin-resistant Staphylococcus aureus (MRSA) causes purulent skin and soft tissue infections as well as other life-threatening diseases. Recent guidelines recommend screening for MRSA at the time of admission. However, few studies have been conducted to determine the prevalence and risk factors for MRSA colonization. A prospective data collection and retrospective analysis was performed. MRSA screening tests were performed using nasal swabs in patients enrolled between January 2017 and July 2018. Demographic data, socio-economic data, medical comorbidities, and other risk factors for MRSA carriage were evaluated among 1577 patients enrolled in the study. The prevalence of MRSA nasal carriage was 7.2%. Univariate regression analysis showed that colonization with MRSA at the time of hospital admission was significantly related to patient age, body mass index, smoking, alcohol, trauma, recent antibiotic use, and route of hospital admission. Multiple logistic regression analysis for the risk factors for positive MRSA nasal carriage showed that being under- or overweight, trauma diagnosis, antibiotic use one month prior to admission, and admission through an emergency department were related to MRSA colonization. This study highlights the importance of a preoperative screening test for patients scheduled to undergo surgery involving implant insertion, particularly those at risk for MRSA.

Introduction The removal of bent intramedullary (IM) nail can become a challenge. Therefore, various methods have been reported for the extraction of nails after femoral refracture. We want to share our successful treatment. Patient concerns Case 1. A 44-year-old man was admitted to our clinic after falling while playing soccer. He complained severe right thigh pain with a visible deformity of the femur. His medical history revealed a right femoral shaft fracture caused in a traffic accident which had been treated with intramedullary nailing. Case 2. A 27-year-old man, who had suffered a right femur fracture after a motorcycle accident and been treated with an IM nail, presented after falling down the stairs. He had severe right thigh pain without any open wound or neurologic deficit. Diagnosis Case 1. Plain radiographs revealed a refracture of the right femoral shaft and a bent IM nail. The initial varus deformity of the nail was 60.1° in the coronal plane. Case 2. The valgus deformity of the nail was 16.1° with an apex-posterior angulation of 34.8° in the sagittal image of plain radiographs. Interventions Case 1. Initial manual reduction was tried in emergency room. Then, under general anesthesia closed reduction of the fracture and bent IM nail was done. After closed reduction, the nail was straightened and extracted smoothly. Case 2. Closed manipulation was attempted initially. But no difference in the deformity was achieved. Therefore, via skin incision, the bent nail was progressively sectioned with high-speed cutting burr until the nail could be straightened. Outcomes Case 1. The patient was mobilized with partial-weight bearing assisted with a crutch on postoperative day two. One year after surgery, the fracture union was complete and the patient was pain-free. Case 2. Six months after surgery, the fracture union was complete with sufficient callus formation around the fracture site. Conclusion There is no gold standard method to remove a bent IM nail. However, since manual reduction to straighten the bent nail causes minimal soft tissue damage, it should be considered first. If it fails, other methods should be attempted, progressing from the minimally invasive technique to more invasive methods.

Retrospective analysis. This study aimed to investigate the characteristics, clinical features, and outcomes of culture-negative (CN) and culture-positive (CP) postoperative spinal infections (PSIs). Causative organism cultures and the use of adequate antibiotics are essential for treating postoperative spinal wound infections. However, managing infected surgical sites with negative wound culture results is a common clinical problem. Although the outcomes of microbiologically confirmed PSIs have been well studied, the outcomes and clinical characteristics of CN PSIs have not been previously published. Between January 1995 and December 2014, 69 patients diagnosed with PSIs were enrolled. Enrolled patients were classified into 2 groups: CN (28 patients) and CP (41 patients). Baseline data, clinical manifestations, specific treatments, and treatment outcomes were compared with the groups. The overall rate of CN PSI was 40.6% (28/69). Baseline data and clinical manifestations were similar between the 2 groups. There were no significant differences in the duration of parenteral antibiotic use between the CN and CP groups. Revision surgery was required less often for the CN group (64.3%) than for the CP group (87.8%) (P = .020). Revision surgeries were repeated 0.82 times/case in the CN group and 1.34 times/case in the CP group (P = .014). Treatment outcomes, such as poor radiologic findings, need for additional anterior surgery, extension of fusion to adjacent segment surgery, and total length of hospital stay, were not different between groups. Revision surgery was performed less often for the CN group than for the CP group. From the perspective of revision surgery, CN PSIs have better prognosis than CP PSIs. However, clinical presentations and radiologic prognoses were not different between the two groups. We suggest that CN PSIs may be treated in the same way as CP PSIs.

Background Although lower urinary tract symptoms (LUTS) show a higher prevalence with age, few studies have reported the trend of these examination tools including uroflowmetry, urodynamic study and cystoscopy. Methods We evaluated the trend of performance of uroflowmetry, urodynamic study and cystoscopy by using National Health Insurance Data from 2010 to 2015. Primary outcome findings included cumulative number of patients per year, cumulative age-standardized patient rate per year and per age group, and correlation between the number of patients per year and the percentage of population per year in each age group. Results The overall trend for frequency of uroflowmetry and cystoscopy showed an increasing pattern (P < 0.001, respectively) while the trend for frequency of urodynamic study showed a decreasing pattern (P < 0.001). After age standardization, the overall trend showed similar results. Correlation between the number of patients per year and the percentage of population per year showed a positive correlation in the 50s age group and the above 70s age group (P = 0.003 and < 0.01, respectively) on uroflowmetry and in the above 70s age group (P < 0.01) on cystoscopy. Urodynamic study showed negative correlations in the 50s age group and the above 60s age group (P = 0.001 and 0.01, respectively). Conclusion National trend for frequency of uroflowmetry, urodynamic study and cystoscopy showed a different trend. The increasing trend of uroflowmetry and cystoscopy was related with growth of the aged population. However, urodynamic study showed a decreasing trend regardless of the age group., Graphical Abstract

Background Although combination therapy with 5 alpha-reductase inhibitor (5ARI) and alpha-blocker is one of the standard interventions in symptomatic benign prostatic hyperplasia (BPH), 5ARI monotherapy is seldom the focus of attention. Adverse events associated with 5ARI include depression and suicidal attempts in addition to persistent erectile dysfunction. The aim of this study is to update our knowledge of clinical efficacy and incidence of adverse events associated with 5ARI treatment in symptomatic BPH. Methods and findings A meta-analysis of randomized controlled clinical trials (RCTs) from 1966 until March, 2017 was performed using database from PubMed, Cochrane Collaboration and Embase. A total of 23395 patients were included in this study and the inclusion criteria were: RCTs with 5ARI and placebo in symptomatic BPH patients. Parameters included prostate specific antigen (PSA), prostate volume (PV), International Prostate Symptom Score (IPPS), post-void residual urine (PVR), voiding symptoms of IPSS (voiding IPSS), maximum urinary flow rate (Qmax), and adverse events (AEs). A meta-analysis with meta-regression was performed for each effect size and adverse events, sensitivity analysis, cumulative analysis along with the analysis of ratio of means (ROM) in the placebo group. A total of 42 studies were included in this study for review, and a total of 37 studies were included in the meta-analysis, including a total of 23395 patients (treatment group: 11392, placebo group: 12003). The effect size of all variables except PVR showed a significant improvement following 5ARI treatment compared with placebo. However, the effect size of differences showed declining trend in PV, IPSS and Qmax according to recent years of publication. In ROM analysis, PV showed no significant increase in the placebo group, with a ROM of 1.00 (95% CI, 0.88, 1.14). The 5ARI treatment resulted in a significantly higher incidence of decreased libido (OR = 1.7; 95% CI, 1.36, 2.13), ejaculatory disorder (OR = 2.94; 95% CI, 2.15, 4.03), gynecomastia (OR = 2.32; 95% CI, 1.41, 3.83), and impotence (OR = 1.74; 95% CI, 1.32, 2.29). Our study has the following limitations: included studies were heterogeneous and direct comparison of efficacy between alpha blocker and 5ARI was not performed. Adverse events including depression or suicidal attempt could not be analyzed in this meta-analysis setting. Conclusions Although there was a significant clinical benefit of 5ARI monotherapy compared with placebo, the effective size was small. Moreover, the risk of adverse events including sexually related complications were high. Additional head-to-head studies are needed to re-evaluate the clinical efficacy of 5ARI compared with alpha-adrenergic receptor blockers.

To determine if a customized growth standard developed for an ethnically homogeneous South Korean population is better at identifying (SGA) fetuses at risk for intra-uterine fetal death (IUFD), compared with a current population based-growth standard.A retrospective cohort study comparing the identification of SGA fetuses at risk for IUFD using a customized versus a population based-chart. The association between a SGA infant defined as a birth weight10th percentile using the South Korean population chart versus the customized chart and IUFD were compared. Intrauterine fetal death was defined as fetal demise occurring after 20 weeks gestation. Statistical analyses including OR, 95% confidence interval (CI), and screening accuracy using each chart were performed.The customized singleton chart identified 11 (8.2%) of the SGA pregnancies detected by the population chart and classified 15 additional fetuses as SGA. Those identified as SGA using the customized chart had an OR for IUFD that was approximately 15 times as high as those identified using the population chart. The customized chart also showed a higher sensitivity and specificity for identifying SGA pregnancies at risk for IUFD.In this ethnically homogenous population, the customized growth chart showed improved discrimination in identifying SGA pregnancies at risk for fetal death than the population-based growth chart.
