Article Synopsis
  • The study examined how myopia affects the thickness and structure of retinal blood vessels using advanced imaging technology in 100 participants.
  • The findings revealed that individuals with high myopia had significantly lower vessel density and thinner retinal layers, particularly noticeable in the superficial and nerve fiber layers.
  • There was a noted correlation between certain ocular parameters, such as axial length to curvature radius ratio, and retinal thickness in non-high myopic eyes, while high myopic eyes showed less correlation in these aspects.

Background: Vesicoureteral reflux (VUR) is a common pediatric urological condition associated with renal scarring, hypertension, and chronic kidney disease. Contrast-enhanced voiding urosonography (ceVUS) has emerged as a promising technique for diagnosing and evaluating VUR, with intrarenal reflux (IRR) often detected using this method. This study aimed to explore the relationship between different VUR grades and IRR on ceVUS, and assess the impact of VUR and IRR on kidney size and function.

Pharyngoesophageal diverticulum (PED) is a rare disease of the esophagus that is usually asymptomatic and often found incidentally during a thyroid ultrasound examination. Due to its anatomical location close to the thyroid, it is easily misdiagnosed as a thyroid nodule, which leads to unnecessary thyroid biopsies and surgical treatment. The occurrence of a single esophageal diverticula is common, while the existence of multiple diverticula is rare.

Background: Early Kasai surgery before 60 days of life results in better clinical outcomes in patients with biliary atresia (BA). We aimed to develop and validate a prediction tool for the early diagnosis of BA in infants younger than 60 days old.

Methods: This prospective study recruited consecutive infants younger than 60 days old with conjugated hyperbilirubinemia who were evaluated with an ultrasound (US) scan, including B-mode US with color Doppler flow imaging (CDFI) features and liver two-dimensional shear wave elastography (2D SWE), from March 2017 to July 2021.

Background: For infants up to 6 months, ultrasound (US) screening of developmental dysplasia of the hip (DDH) is recommended. This cross-sectional study investigated the developmental data of femoral head size and femoral head ossification in mature infant hips and the impact of mild and severe DDH on femoral head development based on US images.

Methods: We reviewed all hip US studies performed from January 2018 to December 2019 to evaluate DDH in infants younger than 6 months at West China Hospital, Sichuan University.

Background: The pandemic of COVID-19 has significantly influenced the epidemiology of intussusception. Nevertheless, the effects of the COVID-19 pandemic on the operation of ultrasound-guided hydrostatic enema reduction (USGHER) for intussusception have been largely unknown.

Methods: The data of pediatric patients with intussusception who were treated by USGHER from January to March of 2019 (Control Group), 2020 (Study Group 1), and 2021 (Study Group 2) in a large Chinese medical institution were retrospectively collected and analyzed.

Background: The failed clearance of jaundice (CJ) in patients with biliary atresia (BA) after the Kasai procedure (KP) often leads to a shorter native liver survival (NLS) time and earlier liver transplantation. We aimed to investigate risk factors of failed CJ and establish a novel nomogram model to predict the status of CJ.

Methods: We retrospectively reviewed institutional medical records from January 2015 to April 2020 and enrolled BA patients post-KP, randomly divided into training and testing cohorts at a ratio of 7:3, and further subdivided into cleared and uncleared jaundice groups.

It is still challenging to make accurate diagnosis of biliary atresia (BA) with sonographic gallbladder images particularly in rural area without relevant expertise. To help diagnose BA based on sonographic gallbladder images, an ensembled deep learning model is developed. The model yields a patient-level sensitivity 93.

Introduction: Biliary atresia (BA) is a life-threatening disease with persistent neonatal cholestasis and progressive liver fibrosis. Timely non-invasive diagnosis of BA can result in early hepatic portoenterostomy (HPE) and better prognosis. Quantitative elastography enables the non-invasive measurement of liver stiffness.

Background: Fetus in fetu (FIF) is a rare congenital anomaly. The preoperative diagnosis of FIF and differentiating it from teratoma and other abdominal tumors can be challenging for radiologists. Clarification of the blood supply and the relationship with the surrounding vessels is especially helpful for successful surgery; however, multimode ultrasound (US) performed for FIF has rarely been explored.

Desmoplastic small round cell tumor (DSRCT) is a rare malignant tumor, which is prone to occur in teenagers DSRCT is a rare malignant tumor that often occurs in adolescents. Early diagnosis is difficult and the prognosis is poor. In this case report, the ultrasonography of DSRCT showed that the huge solid mass was in the abdomen with unclear boundary, irregular shape, insufficient blood supply but without obvious liquefaction and calcification.

Background: Splenogonadal fusion (SGF) is a rare congenital malformation that occurs during embryonic development. SGF typically presents as a left-sided scrotal swelling, left inguinal hernia, scrotal mass, or cryptorchidism. Therefore, it is easily misdiagnosed, and unnecessary orchiectomy may occur.

Objective: To analyze ultrasonic manifestations of eyes of pediatric patients with morning glory syndrome (MGS).

Methods: Clinical data and ultrasound (US) findings for six children (4 males and 2 females, 5-60 months old) diagnosed with MGS between 2005 and 2016 were reviewed.

Results: Of the 12 eyes, seven were diagnosed with MGS; one with cataract; the other four were normal.

A 31-month-old boy with Wilms' tumor (WT), which primarily had originated from the left kidney, was treated with nephrectomy and adjuvant chemotherapy. 2 months after nephrectomy, a left scrotal mass was found at routine follow-up. High-frequency sonography examination revealed an enlarged left testis with a heterogeneous texture and a hypoechoic solid mass in the left scrotum.

Objective: To investigate the application of gluteus maximus transplantation for fecal incontinence after surgery of high anal atresia.

Methods: Between December 2002 and November 2010, 25 patients with fecal incontinence were treated with gluteus maximus transplantation, which was caused by surgery of high anal atresia. There were 11 males and 14 females with an average age of 10.

Objective: To investigate alteration of bladder function in response to surgically reduced bladder capacity by using an awake rabbit model.

Methods: Forty rabbits were divided into two groups, one was experimental group in which the rabbits underwent semi-cystectomy to reduce 50% bladder capacity (n=20), another was control group in which the rabbits received sham operation (n=20). A conventional-fill cystometric investigation was performed as the animal under awake condition at the times of 4 weeks and 8 weeks after operation.
