Purpose:  To investigate how the extent of an ultrasound instructor's clinical expertise influences the level of hands-on ultrasound competency achieved by clinicians after three-day ultrasound courses in abdominal and emergency ultrasound. The second goal was to determine how physicians in residency rate the sonographic and didactic skills of student instructors compared to medical staff instructors.

Method:  A total of N = 100 residents participating in a 3-day ultrasound workshop were randomly trained either by 15 student instructors or by clinical staff physicians, both with > 2 years of teaching experience. Read More

Introduction: Thrombocytopenia, ascites, myelofibrosis, renal dysfunction, and organomegaly (TAFRO) syndrome is a newly recognized and rare clinical subtype of Castleman disease. Renal involvement in TAFRO syndrome usually presents with mild proteinuria, microscopic hematuria, and acute renal injury requiring temporary renal replacement. There is no standard therapy available and treatment failures are common, leading to a poor prognosis. Read More

Introduction: Lumbar hernia is a rare hernia in the posterolateral abdominal wall and only about 310 cases are known to have been reported to date. Laparoscopic hernioplasty is a common surgical approach but is unsuitable for patients who have previously undergone laparotomy and are expected to have extensive visceral adhesions.

Presentation Of Case: An 84-year-old woman who had undergone an open distal gastrectomy was referred to our hospital with an enlarging but easily reducible bulge in the right upper back. Read More

Introduction: Bouveret's syndrome is a rare complication of cholelithiasis that determines an unusual type of gallstone ileus, secondary to an acquired fistula between the gallbladder and either the duodenum or stomach with impaction of a large gallbladder stone. Preoperative diagnosis is difficult because of its rarity and the absence of typical symptoms. Adequate treatment consists of endoscopic or surgical removal of obstructive stone. Read More

As the 2019 novel coronavirus disease (COVID-19) continues to spread, some patients are presenting with abdominal symptoms without respiratory complaints. Our case series documents four patients who presented with abdominal symptoms whose abdominopelvic CT revealed incidental pulmonary parenchymal findings in the imaged lung bases and were subsequently confirmed positive for COVID-19 via laboratory testing. It remains to be seen whether these patients will eventually develop respiratory symptoms. Read More

Background & Aims: Ampullary and duodenal cancer are the leading causes of death in patients with familial adenomatous polyposis (FAP) after colectomy has been performed. Risk of duodenal cancer is determined based on Spigelman stage (SS) of duodenal polyposis. Guidelines recommend endoscopic surveillance of the duodenum and visualization of the papilla to stage duodenal polyposis. Read More

Ceftriaxone is an antibiotic agent frequently used in paediatric hospital practice for the treatment of severe bacterial infections. The use of this agent can result in cholelithiasis and/or biliary sludge, more commonly in children than in adults. This systematic review was aimed at analyzing available literature concerning ceftriaxone-associated biliary pseudolithiasis in paediatric patients, with a special emphasis on the clinical aspects.

BACKGROUND Heterotaxy is a syndrome of abnormal arrangement of the internal thoracic-abdominal structures across the left-right axis of the body. It is a primary disorder with 2 main settings - bilateral left sidedness (polysplenia syndrome) or right sidedness (asplenia syndrome) - although some overlapping or uncertainties may occur. Patients with right heterotaxy typically present with asplenia, complex heart disease, and other thoracoabdominal organ situs abnormalities. Read More

The application of the kerma-area product (PKA) meter is increased rapidly in dosimetry. This study presents measurements of PKA in adherence to the International Atomic Energy Agency protocol for 300 adult patients in digital radiographic procedures. Effective doses (ED) were calculated from PKA measurements and conversion coefficients (E-103/PKA) obtained from the International Commission on radiological protection 103. Read More
