Authors: Hain E, Sindayigaya R, Fawaz J, Gharios J, Bouteloup G, Soyer P, Bertherat J, Prat F, Terris B, Coriat R, Gaujoux S Abstract Introduction: Neuroendocrine tumors of the pancreas (pNETs) represent only 1 to 2% of all pancreatic neoplasms. These tumors can be classified as functional or non-functional tumors; as sporadic or from a genetic origin; as neuroendocrine neoplasms or carcinoma. Over the last decade, diagnosis of pNETs has increased significantly mainly due to the widespread use of cross-sectional imaging. Those tumors are usually associated with a good prognosis. Surgery, the only curative option fo...

ConclusionsManagement of delivery in cases of suspected autosomal recessive renal polycystic kidney disease needs to be discussed because of the risk of abdominal dystocia. The route and timing of delivery depend on the size of the fetal abdominal circumference and the gestational age. The rate of kidney growth must also be taken into account.

In this study, we compared different anesthesia and operation methods for modeling VX2 hepatocarcinoma in rabbits. Forty New Zealand white rabbits were randomly divided into three groups: A, B, and C. Group A underwent ultrasound-guided implantation and intravenous anesthesia; Group B underwent ultrasound-guided implantation and inhalation anesthesia; Group C underwent laparotomy implantation and intravenous anesthesia. Anesthesia and operation differences were compared between groups A and B, and A and C, respectively. We used magnetic resonance imaging (MRI) to assess tumor formation and growth, and pathological examinat...

ConclusionWith the proper technique and knowledge of the ankle anatomy, high-frequency US proved to be an effective imaging modality in the diagnosis of CFL lesions in chronic lateral ankle injuries. US had a high sensitivity and specificity in the evaluation of the CFL when MRI findings were regarded as the reference standard.

Recently revised international guidelines for hepatocellular carcinoma (HCC) suggest that selected patients with inadequate surveillance ultrasonography to be assessed by alternative imaging modalities such as computed tomography or magnetic resonance imaging (MRI). MRI with contrast material has drawbacks associated with the use of gadolinium contrast agent. Non-enhanced MRI consisted of diffusion-weighted imaging and T2-weighted imaging showed significantly better performance than ultrasonography as a surveillance tool for HCC in a high-risk prospective cohort. The estimated scan time of non-enhanced MRI was less than 6 ...

CONCLUSIONS: At the moment, we are uncertain whether rotator cuff repair surgery provides clinically meaningful benefits to people with symptomatic tears; it may provide little or no clinically important benefits with respect to pain, function, overall quality of life or participant-rated global assessment of treatment success when compared with non-operative treatment. Surgery may not improve shoulder pain or function compared with exercises, with or without glucocorticoid injections. The trials included have methodology concerns and none included a placebo control. They included participants with mostly small degenerativ...

This study aimed to investigate the safety and efficacy of MRgFUS for PD by systematically reviewing related literature. PubMed and EMBASE were searched to identify related studies. Inclusion criteria were (1) reported the efficacy or sa fety of MRgFUS for PD and (2) published in English. Exclusion criteria were (1) nonhuman study, (2) review or meta-analysis or other literature types without original data, and (3) conference abstract without full text. Data on study characteristics, treatment parameters, efficacy, and adverse event s were collected. Descriptive synthesis of data was performed. Eleven studies containing 80...

Abstract CLINICAL PROBLEM: Sudden chest pain and sudden abdominal pain are among the most common reasons that lead patients to the emergency room. The heterogeneous field of possible, sometimes serious diagnoses requires a structured and rapid interdisciplinary clarification in order to be able to promptly provide patients with an adequate therapy. STANDARD RADIOLOGICAL PROCEDURES: Knowing the "usual suspects" of sudden chest and abdominal pain enables the radiologist to quickly select the appropriate imaging method that allows a diagnosis to be made without delay. In addition to pain loca...

CONCLUSIONS: This smartphone application coupled with targeting device can be used in various settings such as EVD placement in hydrocephalus and in other brain targeting candidates in emergency settings. Also, it may be used in any emergency or neurosurgery department centers with no access to advanced neuro-imaging facilities, only using patient's simple cranial measures to achieve acceptable and highly accurate brain targeting compared with conventional, time consuming and costly techniques. We plan to expand this study to clinical trials for further evaluation. PMID: 31802048 [PubMed - in process]
