Four patients who had a preserved ARM node did not develop lymphedema. One patient whose ARM node was not preserved due to SLN identification failure did not develop postoperative lymphedema. One patient who underwent ALND without ARM node conservation because of metastatic SLN on frozen section examination developed postoperative lymphedema.

ARM is oncologically safe, decreases the incidence of postoperative lymphedema, and allows for the early detection of postoperative lymphedema in patients who underwent ALND. Ultimately, ARM may help improve the quality of life of patients with pathologic node-positive breast cancer.

Currently, breast cancer is divided into Luminal A, Luminal B, HER-2 overexpression (HER-2) and basal cell at genetic level. However, the differential diagnosis of estrogen receptor (ER)-positive breast cancer subtypes is rare. Therefore, we aimed to investigate the feasibility of identifying the ER-positive breast cancer subtypes based on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) texture analysis.

A retrospective analysis was performed for clinical data of 51 patients with ER-positive breast invasive ductal carcinoma confirmed by surgery and pathology from January 20 to October 2018. FireVoxel texture analysis software was used to delineate the tumor boundary layer by layer. The differences in the above characteristics between Luminal A and Luminal B breast cancer were compared, and the diagnostic efficacy of statistically significant texture parameters for ER-positive breast cancer subtypes was analyzed.

There were no significant differences in mean, standard deviation (SD), skewness and tumor size between Luminal A and Luminal B groups (P>0.05). The kurtosis, inhomogeneity and entropy could effectively distinguish between the two groups with statistically significant difference (P=0.001, P=0.000, and P=0.000). The area under the receiver operating characteristic (ROC) curve (AUC) of kurtosis, inhomogeneity and entropy diagnosed with malignant mass were 0.832, 0.859 and 0.891, respectively (P<0.01). In addition, the entropy was the best among the three indicators. NHWD-870 research buy When the entropy was ≤4.22, the sensitivity of the diagnosis Luminal B was 90.62% and the specificity was 78.95%.

The texture analysis features based on DCE-MRI can help to identify ER-positive breast cancer subtypes. Entropy can be the best single texture indicator.

This study aimed to investigate electronic medical record (EMR) implementation in a busy urban academic emergency department (ED) and to determine the frequency, duration, and predictors of EMR downtime episodes.

This study retrospectively analyzed data collected real time by the EMR and by the operations group at the study ED from May 2016 to December 2017. The study center has used the First Net Millennium EMR (Cerner Corporation, Kansas City, Missouri, USA). The ED operations data have been downloaded weekly from the EMR and transferred to the analytics software Stata (version 15MP, StataCorp, College Station, Texas, USA).

During the study period, 12 episodes of EMRD occurred, with a total of 58 hours and a mean of 4.8±2.7 hours. The occurrence of EMRD event has not been associated with on-duty physician coverage levels (

0.831), month (

0.850), or clinical shift (morning, evening, or night shift) (

0.423). However, EMRD occurrence has been statistically significantly associated with weekdays (

0.020).

In a real-world implementation of EMR in a busy ED, EMRD episodes averaging approximately 5 hours occurred at unpredictable intervals, with a frequency that remained unchanged over the first 20 months of the EMR deployment.

The study could define downtime characteristics at the study center. The EMRD episodes have been associated with inaccuracies in hourly census reporting, with a rebound phenomenon of over-reporting in the first hour or two after restoration of EMR operations.

In this report, we describe a case of a six-year-old female patient who experienced dysuria for eight days. Color ultrasound of the patient's urinary system revealed a solid nodule 14×9 mm in size at the opening of the urethra in the trigonal area of the bladder. The nodule was connected to the urethra's posterior wall, and no blood flow signal could be detected. The primary diagnosis was urethral mass. A F7 ureteroscope was used as the cystourethroscope and was inserted into the bladder via the external opening of the urethra. Biopsy forceps were used to remove pathological lesions from the uplifted mucosa and submucosa. The postoperative pathological report was urethral polyp. When a child experiences intermittent urine retention, intermittent hematuria, and intermittent lower urinary tract symptoms, urethral polyp should be considered first.Congenital lobar emphysema (CLE) is a rare congenital anomaly of lung. It presents different respiratory symptoms due to affected lobar emphysema, compression atelectasis and mediastinal shift. It can affect one or more lobes. There is usually no typical clinical manifestation in clinic. Typical X-ray can help to diagnose. We report a case of neonatal CLE, which first appeared in the right middle lobar. After right middle lobe (RML) lobectomy, respiratory distress appeared again. Emphysema was found again in the left lower lung. The multiple lobes emphysema appear at different times, and this case occurred after lobectomy.
