Ran Zhu, Xiao-Chun Ma
Pulmonary embolism (PE) is a clinical emergency that will increase the mortality if complicated with unstable hemodynamics. Because of its nonspecific clinical symptoms, it's a great challenge to make a PE diagnosis. The golden standard to diagnose PE is computed tomography of pulmonary artery (CTPA), but a diagnosis of PE also composed of evaluation of PE risk factors, possibilities, and risk stratification. Ultrasonography may detect right ventricle strain related to hemodynamic change, intravascular thrombosis, thrombosis in right heart or pulmonary arteries, pulmonary infarction, and local pleural effusion...

Takayasu arteritis (TA) is a chronic inflammatory disease of unknown origin that involves large and mediumsized arteries, primarily the aorta and its major branches. TA is a therapeutic challenge because corticosteroids and conventional immunosuppressive agents are not always effective or safe. Interleukin 6 (IL-6) has emerged as a key cytokine in the pathogenesis of TA and its serum levels have been shown to well correlate with disease activity. We report a 19 years old female patient with TA refractory to conventional immunosuppressive agents, successfully treated with subcutaneous tocilizumab, a humanized monoclonal antibody against IL-6 receptor, in which ultrasonography (US) was used as imaging tool to follow up the patient...

Imaging of the gallbladder has a key role in the examination of patients with abdominal pain-especially pain localized to the right upper quadrant. Pathologic conditions that affect the gallbladder include cholelithiasis and associated complications such as acute and chronic cholecystitis, choledocholithiasis, gallstone pancreatitis, and cancer. Modalities used to image the gallbladder include ultrasonography (US), computed tomography (CT), magnetic resonance (MR) imaging, and nuclear scintigraphy. US is the primary imaging modality used to evaluate entities suspected of being gallbladder disease, as it is both sensitive and specific for demonstrating gallstones, biliary duct dilatation, and inflammatory features...

Klebsiella pneumoniae is an opportunistic nosocomial pathogen belonging to the Enterobacteriaceae family that is associated with a wide range of infections. In the 1980s a new hypervirulent (hypermucoviscous) variant of Klebsiella pneumoniae (hvKP) emerged in southeast Asia and is now increasingly spreading to Western countries due to an invasive syndrome. hvKP isolates can cause serious, life-threatening community-acquired infections in younger healthy hosts, including liver abscess, pneumonia, meningitis and endophthalmitis...

INTRODUCTION: Gastric glomus tumors are rare submucosal mesenchymal tumors. Because gastric glomus tumors are submucosal tumors and resemble gastrointestinal stromal tumors (GISTs), preoperative diagnosis is difficult. We present a case of gastric glomus tumor that was removed by laparoscopy endoscopy cooperative surgery (LECS). CASE PRESENTATION: A 67-year-old female was taken to the emergency room at our hospital due to epigastric pain. An upper gastrointestinal endoscopy revealed a submucosal tumor (SMT) located in the lesser curvature of the upper body of the stomach...

This paper reviews that state of our knowledge concerning follicular wave dynamics, monitoring and manipulation. All camelids have overlapping follicular waves in absence of ovulation which is induced by a seminal plasma factor (βNGF). The interval between follicular waves varies. The size of the ovulatory follicle varies between 11 and 25 mm in camels and between in 6 and 13 mm in South American Camelids. The interval between induction of ovulation and next ovulatory follicle is 15 ± 1 day for all camelids...

Emergent exploratory laparotomy is recommended for hemodynamically unstable blunt trauma patients suspected of having hemoperitoneum. However, given the unreliability of ultrasonography and rapid scan speed of computed tomography (CT), CT might help clinicians provide accurate information even in hemodynamically unstable trauma patients. This observational study aimed to describe the bleeding site and hospital course of severe blunt trauma patients with hemoperitoneum diagnosed by CT scan.We enrolled all consecutive adult blunt trauma patients (≥18 years old) who underwent whole-body CT before operation between February 2012 and October 2016...

INTRODUCTION: Ureteroscopy has been shown to be a highly efficacious and safe modality for the treatment of pediatric urolithiasis. However, conventional ureteroscopy relies on fluoroscopy for intraoperative guidance, exposing both patient and operating room personnel to ionizing radiation. Pediatric urolithiasis patients are at a particularly increased risk from this radiation exposure. The use of ultrasound in place of fluoroscopy for intraoperative guidance has emerged as one modification that can reduce radiation exposure during ureteroscopy...

Pediatric pancreatic injuries are rare. We present an atypical case that occurred in a 4-year-old male. The child presented with a twenty-four-hour history of vomiting that had progressed to right lower quadrant abdominal pain on examination in the emergency department. The initial differential was gastroenteritis versus appendicitis. An abnormality on the ultrasonography and an elevated lipase level eventually led to an MRI showing a complete transection through the posterior margin of the pancreas. The patient was admitted to pediatric surgery and underwent a successful distal pancreatectomy with preservation of the spleen...
