Both endoscopic ultrasonography （EUS）-guided choledochoduodenostomy （EUS-CDS） and EUSguidedhepaticogastrostomy （EUS-HGS） are relativelywell established as alternatives to percutaneoustranshepatic ...biliary drainage （PTBD）. Both EUSCDSand EUS-HGS have high technical and clinicalsuccess rates （more than 90%） in high-volume centers.Complications for both procedures remain high at10%-30%. Procedures performed by endoscopistswho have done fewer than 20 cases sometimes resultin severe or fatal complications. When learning EUSguidedbiliary drainage （EUS-BD）, we recommend amentor＇s supervision during at least the first 20 cases.For inoperable malignant lower biliary obstruction,a skillful endoscopist should perform EUS-BD beforeEUS-guided rendezvous technique （EUS-RV） andPTBD. We should be select EUS-BD for patientshaving altered anatomy from malignant tumors beforeballoon-enteroscope-assisted endoscopic retrogradecholangiopancreatography, EUS-RV, and PTBD. Ifboth EUS-CDS and EUS-HGS are available, we shouldselect EUS-CDS, according to published data. EUSBDwill potentially become a first-line biliary drainageprocedure in the near future.
This narrative review focuses on thoracic ultrasonography (lung and pleural) with the aim of outlining its utility for the critical care clinician. The article summarizes the applications of thoracic ...ultrasonography for the evaluation and management of pneumothorax, pleural effusion, acute dyspnea, pulmonary edema, pulmonary embolism, pneumonia, interstitial processes, and the patient on mechanical ventilatory support. Mastery of lung and pleural ultrasonography allows the intensivist to rapidly diagnose and guide the management of a wide variety of disease processes that are common features of critical illness. Its ease of use, rapidity, repeatability, and reliability make thoracic ultrasonography the “go to” modality for imaging the lung and pleura in an efficient, cost effective, and safe manner, such that it can largely replace chest imaging in critical care practice. It is best used in conjunction with other components of critical care ultrasonography to yield a comprehensive evaluation of the critically ill patient at point of care.
This book is a comprehensive reference and practical guide on the technology and application of ultrasound to the musculoskeletal system. It is organized into two main sections. The first is devoted ...to general aspects, while the second provides a systematic overview of the applications of musculoskeletal ultrasound in different areas of the body. Each chapter of the second section provides an introduction on clinical anatomy and the essentials of clinical history and physical examination. Thereafter, performance of the ultrasound study is explained and the normal and pathological anatomy is reviewed. To assist in understanding, the ultrasound scans are correlated with drawings, photographs, images obtained using other modalities, and anatomic specimens. There is a generous complement of high-quality illustrations based on high-end equipment. This book contains a wealth of invaluable information.
Objective
This study aimed to identify the sonographic features of pathologically confirmed onychopapilloma cases.
Methods
High‐frequency up to 24 MHz and ultra‐high frequency‐ultrasound up to 71 MHz ...examinations were performed and correlated with their clinical and pathologic presentations.
Results
Twenty‐two cases met the criteria. Clinical presentations revealed longitudinal erythronychia in 63.3% of cases. The ultrasound examinations identified a hypoechoic band in the nail bed (86.3%), nail plate abnormalities including upward displacement (68.2%) and thickening (68.1%), focal hyperechoic focal spots on the nail plate (50%) and irregularities of the ventral plate (33.3%).
Color Doppler imaging showed no hypervascularity of the nail bed in all studies. These findings correlate with histological characteristics of onychopapilloma, including nail bed acanthosis, papillomatosis, and layered hyperkeratosis. Recurrence occurred in two cases after surgery, with tumors showing proximal extension in the matrix region on ultrasound not evident during clinical examination.
Conclusion
High‐frequency and ultra‐high‐frequency can provide anatomical information in onychopapilloma that could enhance understanding and management.
