Small intestinal epiploic foramen entrapment in a seven-month pregnant Thoroughbred mare: a case report

A seven-month pregnant four-year-old Thoroughbred mare with colic weighing 600 kg was referred to the Jeju National University Equine Hospital. A physical examination and ultrasound suggested epiploic foramen entrapment. The patient underwent ileum resection and end-to-side jejunocecostomy. After surgery, the horse showed a consistent pain when introduced to feeding. A repeat laparotomy was performed to enlarge the stoma size with side-to-side jejunocecostomy. The repeat laparotomy was successful, and the mare gave birth uneventfully. This report describes a case of small intestinal epiploic foramen entrapment and the clinical outcomes of the 2 consecutive laparotomies a Thoroughbred mare in late gestation.

A Case of Dermatomyositis in a Patient with a Neuroendocrine Tumor at the Ampulla of Vater / 대한내과학회지

Dermatomyositis is an autoimmune disease characterized by chronic muscle inflammation that results in specific dermatological signs and decreased muscle strength. It is known to have a strong association with malignancy. Most neuroendocrine tumors arise from the gastrointestinal tract, with less than 1% of cases occurring at the ampulla of Vater. While cases of dermatomyositis associated with neuroendocrine tumors have been reported internationally, to date there have been no cases reported in Korea. This case report presents a 33-year-old male who had undergone pylorus-preserving pancreaticoduodenectomy for a neuroendocrine tumor located at the ampulla of Vater, and had been followed at the hospital after his procedure. Three years post-surgery, the patient developed serious muscle weakness in his upper-right and lower-left extremities, and was subsequently diagnosed with dermatomyositis. This paper presents the first domestic case of dermatomyositis developing in the context of a neuroendocrine tumor at the ampulla of Vater. A literature review on this subject follows in the discussion.

Recent Trends of Ultrasound in Rheumatology

Owing to the ability of musculoskeletal ultrasound (US) to depict cross sectional images of synovial joint and related structures, US has become the most reliable tool for evaluation of arthritic activity of rheumatoid arthritis (RA). US can detect early synovitis, assess disease activity, and determine true remission in patients with RA. US also can detect early enthesitis in patients with spondyloarthropathies. In addition, US can provide a reliable tool for measuring skin thickness in patients with systemic sclerosis. With guidance of injection or aspiration, US can result in a better clinical outcome. Thus, educational needs and research networks are increasing. We present a review of rheumatology US, focusing on recent trends and advances.

Non-Bacterial Thrombotic Endocarditis in a Patient with Rheumatoid Arthritis

Rheumatoid arthritis (RA) is frequently associated with various extra-joint complications. Although rare, thromboembolic complications are associated with high morbidity and mortality. We experienced a very rare case of nonbacterial thrombotic endocarditis (NBTE) and subsequent embolic stroke in a patient with RA. A 72-year-old male with a 15-year history of RA suddenly developed neurologic symptoms of vomiting and dizziness. Brain magnetic resonance imaging revealed recently developed multiple cerebellar and cerebral lacunar infarctions. Echocardiography showed a pulsating mitral valve vegetation involving the posterior cusp of the mitral valve leaflet, which was confirmed as NBTE. Immediate anti-coagulation therapy was started. The NBTE lesion disappeared in follow-up echocardiography after 4 weeks of anti-coagulation treatment.

Idiopathic Retroperitoneal Fibrosis Associated with Rheumatoid Arthritis in a Patient with Concomitant Chronic B Viral Hepatitis

Retroperitoneal fibrosis (RPF) is a rare, progressive disease characterized by chronic non specific inflammation of the retroperitoneum. Although the pathogenesis of idiopathic retroperitoneal fibrosis (IRF) remains unclear, IRF has been reported in association with autoimmune disorders. However, few cases of IRF associated with rheumatoid arthritis (RA) have been reported. We experienced a rare case of IRF in a patient with RA and chronic B viral hepatitis. A 39-year-old Korean man with RA and hepatitis B was referred to our hospital due to left hydronephrosis. An abdominal computed tomography (CT) scan and magnetic resonance imaging (MRI) showed a diffuse infiltrating retroperitoneal mass around the abdominal aorta and left ureter. The patient underwent intraureteral stent insertion and was treated with corticosteroid. Three months later, the follow up abdominal CT showed that the retroperitoneal mass had decreased in size. Herein, we report the first case of coexistent IRF, RA, and chronic B viral hepatitis with a literature review.

Knee Synovitis Mimicking a Septic Arthritis

Synovitis is the inflammation of the synovial membrane with unknown etiology which occurs in association with auto-immune inflammatory arthritis, mainly in rheumatoid arthritis. Synovitis manifesting as rapidly progressing monoarticular or pauciarticualr symptoms could make early diagnosis difficult, thus it could be misdiagnosed as other forms of arthritic diseases. We experienced a rare case of knee joint synovitis which initially manifested as mimicking a septic arthritis. A 58-year-old-male patient underwent renovascular embolization due to retroperitoneal hemorrhage which was developed after renal biopsy. Suddenly, the patient's left knee joint became swollen rapidly with redness and tenderness. Moreover, his right knee also became inflamed. Surgical irrigation and intravenous antibiotics had never worked on his knee joint inflammation, however administration of intermediate dose of steroid could decrease inflammatory signs dramatically. Synovitis in a large joint could be mistaken as a septic arthritis, delaying the right diagnosis. Thus, we report this case with literature review.

Value of Ultrasound in Rheumatologic Diseases

The use of musculoskeletal ultrasound in rheumatology clinical practice has rapidly increased over the past decade. Ultrasound has enabled rheumatologists to diagnose, prognosticate and monitor disease outcome. Although international standardization remains a concern still, the use of ultrasound in rheumatology is expected to grow further as costs fall and the opportunity to train in the technique improves. We present a review of value of ultrasound, focusing on major applications of ultrasound in rheumatologic diseases.
