Among parasitic hepatic cystic lesions, the most common disease is represented by cystic echinococcosis, especially in high endemic countries. European epidemiology of cystic echinococcosis in children is very difficult to assess because of under-reporting but is increasing, because of high immigration flows from endemic countries and an increased awareness. Hydatidosis can be localized in every part of the body. The liver and lungs are the most common localizations in both children and adults. Multi-organ involvement is rarely reported in children...

Breast cancer-related lymphedema (BCRL) is a consequence of a malfunctioning lymphatic drainage system resulting from surgery or some other form of treatment. In the initial stages, minor and reversible increases in fluid volume of the arm are evident. As the stages progress over time, the underlying pathophysiology dramatically changes with an irreversible increase in arm volume most likely due to a chronic local inflammation leading to adipose tissue hypertrophy and fibrosis. Clinicians have subjective ways to stage the degree and severity such as the pitting test which entails manually comparing the elasticity of the affected and unaffected arms...

Introduction: The search for an accurate and predictable method to estimate the endotracheal tube (ETT) size in pediatric population had led to derivation of many formulae. Of this, age-based formulae are the most commonly used. Studies have shown that minimal transverse diameter of subglottic airway (MTDSA) measurements using a high-frequency probe improves the success rate of predicting the airway diameter to about 90%. We did a prospective observational study using MTDSA as the criteria to select the size of ETT in children with congenital heart disease...

INTRODUCTION: Procedures involving the small saphenous vein (SSV) can result in sural nerve (SN) damage due to the proximity of the two structures. The relationship between the SN and SSV has previously been described in cadaveric studies with limited scope on surface landmarks. This study investigates the relationship between the SN and SSV in-vivo through ultrasound. MATERIALS AND METHODS: Transverse/short-axis ultrasound scans of 128 legs (64 healthy participants) were taken by a single observer using a GE Logiq e ultrasound system with a 5-13Hz linear transducer (GE Logiq 12L-RS)...

BACKGROUND: The prognosis for pancreatic cancer remains poor despite diagnostic advances and treatments with new chemotherapeutic regimens. The five year survival rate remains below 3%. Consequently, there is an urgent need for new treatments to significantly improve the prognosis. In addition, there is a big gap in terms of the screening, early diagnosis and prevention of pancreatic cancer the incidence of which is increasing dramatically. METHODS: Design: the BACAP cohort is a prospective multicenter pancreatic cancer cohort (pancreatic ductal carcinoma) with clinical and multiple biological samples; Participating centers: 15 French academic and private hospitals; Study Population: any cytologically and/or histologically proven pancreatic carcinoma regardless of the stage (resectable, borderline, locally advanced or metastatic) or treatment (surgery, palliative chemotherapy, best supportive care)...

A 61-year-old woman with locally advanced, high-grade urothelial cell carcinoma was treated with the anti-programmed death-ligand 1 antibody atezolizumab. She initially received neoadjuvant chemotherapy and surgery that led to clinical and radiographic remission at the time of atezolizumab initiation. Within 3 months she developed new mediastinal and hilar lymphadenopathy as well as pulmonary nodules in a pattern characteristic of pulmonary sarcoidosis. Mediastinal lymph node biopsy by endobronchial ultrasound demonstrated noncaseating granulomas without evidence of malignancy or infection...

A healthy 37 - year - old woman referred to our clinic with one - year history of recurrent urinary tract infection, dysuria and frequency. Her past medical history informed us that an IUD (Copper TCu380A) had been inserted 11 years ago. Eleven months after the IUD insertion she had become pregnant, unexpectedly. At that time, she had undergone gynecological examination and abdominal ultrasound study. However, the IUD had not been found, and the gynecologist had made the diagnosis of spontaneous fall out of the IUD...

In 2018, the American Cancer Society (ACS) estimates that 164,690 new cases of prostate cancer will be diagnosed and 29,430 will die due to the prostate cancer in the United States (Siegel et al., CA Cancer J Clin 67:7-30, 2018). Many men with prostate cancer are often managed with aggressive therapy including radiotherapy or surgery. No matter how expertly done, these therapies carry significant risk and morbidity to the patient's health related quality of life with impact on sexual, urinary and bowel function (Potosky et al...

A miniature forward-viewing endoscopic probe that provides high-resolution 3D photoacoustic images is demonstrated. The probe is of outer diameter 3.2 mm and comprised of a transparent Fabry-Pérot (FP) polymer-film ultrasound sensor that is located at the distal end of a rigid optical fiber bundle. Excitation laser pulses are coupled simultaneously into all cores of the bundle and are transmitted through the FP sensor to provide wide-field tissue illumination at the distal end. The resulting photoacoustic waves are mapped in 2D by sequentially scanning the input end of the bundle with an interrogation laser beam in order to individually address different points on the FP sensor...

In focused ultrasound (FUS) thermal ablation of diseased tissue, acoustic beam and thermal simulations enable treatment planning and optimization. In this study, a treatment-planning methodology that uses the hybrid angular spectrum (HAS) method and the Pennes' bioheat equation (PBHE) is experimentally validated in homogeneous tissue-mimicking phantoms. Simulated three-dimensional temperature profiles are compared to volumetric MR thermometry imaging (MRTI) of FUS sonications in the phantoms, whose acoustic and thermal properties are independently measured...

In the last decades, an increasing interest has developed towards non-invasive breast lesion treatments, which offer advantages such as the lack of surgery-related complications, better cosmetic outcomes, and less psychological distress. In addition, these treatments could be an option for patients with poor health who are not candidates for surgery. Non-surgical ablation can be performed under magnetic resonance (MR) or ultrasound (US) guidance. US is cheaper and easily available, while contrast-enhanced MR is more accurate, ensuring better safety and efficacy for the patient...
