To describe the effectiveness and security of DSA-guided percutaneous sclerotherapy for venous malformations of penile region in children.

A total of 9 cases children with penile venous malformations treated by DSA-guided percutaneous sclerotherapy from January 2017 to June 2018 were enrolled in this study. Local angiography was performed under DSA fluoroscopy, and the shape, extent and venous drainage of the tumor nest were judged. Then sclerosing agents (Pingyangmycin and Polidocanol) were selected according to the flow rate of angiography and treated by percutaneous injection under DSA monitoring. Imaging examination (MRI) was performed to evaluate clinical improvement.

A total of 26 interventional sclerotherapy sessions were performed in 9 children, with an average of (2.3±0.5) sessions per case. After a mean follow-up of 7.3 months, 6 cases were cured, and 3 cases were in basic remission. There were 9 cases of temporary edema secondary to the treatment site and 3 cases of mild pain. No serious complications such as ulceration, hemorrhage, infection and dysfunction occurred in any patients.

DSA-guided percutaneous sclerotherapy for venous malformations of penile region in children is safe and effective, does not affect the appearance and function of penis, and is worthy of clinical promotion.

Despite being mandated by cooperative groups, omission of nodal sampling is the most frequent protocol deviation in surgery for Wilms tumor. The stations as well as the number of nodes that should be sampled are not clearly defined resulting in a marked variation in practices among surgeons. We propose a systematic method for nodal sampling intending to reduce interoperator variation. In this study, we have assessed the feasibility and yield of systematic lymph node sampling and also evaluated the factors influencing nodal metastasis.

Prospective evaluation of 113 Wilms tumor patients operated at a single tertiary cancer center between 2015 and 2019. Climbazole chemical structure All these patients underwent a systematic 5-station nodal sampling.

Median lymph node yield was 8 and 13.2% (15/113) patients harbored a histologically positive nodal disease. Of the patients with positive nodal disease, interaortocaval nodes had metastasis in 46.7% (n = 7). They represented isolated sites of nodal disease (skip metastases) in 28.6% (n = 4) of patients. Right-sided tumors had more frequent involvement of interaortocaval nodes and skip disease. Tumors with high-risk histology had 12.5 times more odds of harboring nodal disease as compared to low and intermediate-risk histology Wilms tumor.

The proposed method of systematic station wise sampling provides a template to guide surgeons in performing lymph node harvesting. Interaortocaval nodes sampling should be performed routinely as the incidence of disease at this station is sufficiently high and metastasis may skip hilar nodes.

To determine whether findings from lung ultrasound and chest high-resolution computed tomography (HRCT) correlate when evaluating COVID-19 pulmonary involvement.

The present prospective single-centre study included consecutive symptomatic patients with reverse transcription polymerase chain reaction (RT-PCR)-proven COVID-19 who were not in the intensive care unit. All patients were assessed using HRCT and ultrasound of the lungs by distinct operators blinded to each other's findings. The number of areas (0-12) with B-lines and/or consolidations was evaluated using ultrasound and compared to the percentage and classification (absent or limited, <10%; moderate, 10-25%; extensive, 25-50%; severe, 50-75%; critical, >75%) of lung involvement on chest HRCT.

Data were analysed for 21 patients with COVID-19 (median [range] age 65 [37-90] years, 76% male) and excellent correlation was found between the ultrasound score for B-lines and the classification (p<0.01) and percentage of lung involvement on chest HRCT (r=0.935, p<0.001). In addition, the ultrasound score correlated positively with supplemental oxygen therapy (r=0.45, p=0.041) and negatively with minimal oxygen saturation at ambient air (r=-0.652, p<0.01).

The present study suggests that among COVID-19 patients, lung ultrasound and HRCT findings agree in quantifying lung involvement and oxygen parameters. In the context of the COVID-19 pandemic, lung ultrasound could be a relevant alternative to chest HRCT.

Although some pathologies affecting this region are commonly seen elsewhere in the skeleton, they may have atypical imaging appearances and morphological characteristics when present at the tibial tuberosity. The present review describes the developmental stages of the tibial tuberosity, explaining why this area is prone to degenerative tractional changes and injury, and also highlights various pathologies including benign and malignant osseous lesions and trauma/degenerative related abnormalities.
The usefulness of the combined assessment of HbA1c and plasma glucose (PG) in acute myocardial infarction (AMI) in non-diabetic patients remains unclear.

In a large observational study, we aimed to identify the prognostic values of these biomarkers regarding one-year all-cause mortality in non-diabetic patients after AMI.

From the "obseRvatoire des Infarctus de Côte d'Or" (RICO) survey database, we included all consecutive non-diabetic patients with AMI (n=6617) from May 2001 to December 2016. Exclusion criteria were admission known or unknown diabetes, in-hospital death. The primary endpoint was all-cause one-year mortality. The secondary endpoints were MACE, infarct size, LVEF<40% and GRACE risk score. Cut-off levels (high/low) were determined by ROC curve analysis for the prediction of one-year death (HbA1c 5.9% and PG 131mg/dL) to set up 4 groups low HbA1c/low glucose (n=3158), low HbA1c/high glucose (n=1264), high HbA1c/low glucose (n=1378) and high HbA1c/high glucose (n=817).

Elevation of PG was associated with elevated rate of LVEF<40%, STEMI, anterior wall location, DFG<60mL/min/m
and higher troponin Ic pic (all P<0.
