Staphylococcus lugdunensis (S. lugdunensis) is a coagulase negative staphylococcus (CoNS) that can cause destructive infective endocarditis. S. lugdunensis, unlike other CoNS, should be considered to be a pathogen. We report the first case of S. lugdunensis endocarditis causing ventricular septal defect and destruction of the aortic and mitral valves. A 53-year-old male with morbid obesity and COPD presented with intermittent fever and progressive shortness of breath for 2 weeks. Chest examination showed bilateral basal crepitations, and a grade 2 systolic murmur along the right sternal border...

Because of advancements in fetal imaging, anatomic variants of the genitourinary tract are most often discovered in the antenatal period. As such, general internists are less likely to encounter adult patients with previously undiagnosed anatomic abnormalities of the renal collecting system, such as duplicated kidneys. These abnormalities put patients at risk for urinary obstruction and recurrent infections of the urinary tract. We report the case of a 40-year-old diabetic patient with a previously undiagnosed duplex kidney who had recurrent episodes of diabetic ketoacidosis triggered by urinary tract infections...

Yuyi Yeow, Yew-Lam Chong
Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic pyelonephritis with progressive loss of renal function. Commonly, obstructing urinary calculi are seen. It is difficult to differentiate between XGPN and malignancy in many cases, and the diagnosis is usually only confirmed post-operatively upon histopathological examination of the specimen. Surgical treatment is often the main treatment modality due to suspicion for malignancy. Here, we present a case of XGPN that presented with abdominal distension, which was eventually discovered to be due to a preperitoneal abscess...

INTRODUCTION: Post-transplant lymphoproliferative disease (PTLD) comprises a variety of lymphoid and plasma cell disorders arising in patients with a solid organ transplant. Monomorphic lymphomas represent the most significant part of this wide spectrum, with the overall risk rising with the aggressiveness of lymphoid proliferation in comparison to the general population. The development of Hodgkin lymphoma is very rare in transplant recipients, comprising less than 6% of all monomorphic PTLD, while cases of primary intestinal Hodgkin lymphoma in these circumstances are anecdotal...

BACKGROUND: Renal cell carcinoma (RCC) represents the most common malignant epithelial neoplasm of the kidney. Accurate assessment of the renal masses, defining the histologic subtype and the grade of differentiation of the tumor, is vital to ensure an adequate case management as well as for staging and prognosis. Recently, diffusion-weighted imaging (DWI) magnetic resonance imaging (MRI) tends to be increasingly appealing for the clinicians as an imaging procedure of choice for the diagnosis and staging of the RCC, which is predetermined by several advantages over CT...

Based on microscopic and immunohistochemical characterization, we documented spontaneous proliferative and neoplastic lesions in the thyroid and parathyroid glands of nondomestic felids. Ten animals (4 leopards, 3 tigers, and 3 cougars), all with a previous diagnosis of thyroid neoplasia were identified from the University of Tennessee College of Veterinary Medicine database. The mean age of affected animals was 15.9 y. Twelve neoplasms were identified; 2 animals had 2 concurrent neoplasms. After immunohistochemical characterization using a panel of chromogranin A, thyroglobulin, and calcitonin, 7 of the former thyroid neoplasms were diagnosed as thyroid adenomas, 1 was diagnosed as a thyroid carcinoma, and 4 were diagnosed as parathyroid adenomas...

INTRODUCTION: Immune cells utilize acetylcholine as a paracrine-signaling molecule. Many white blood cells express components of the cholinergic signaling pathway, and these are up-regulated when immune cells are activated. However, in vivo molecular imaging of cholinergic signaling in the context of inflammation has not previously been investigated. METHODS: We performed positron emission tomography (PET) using the glucose analogue 18F-FDG, and 11C-donepezil and 18F-FEOBV, markers of acetylcholinesterase and the vesicular acetylcholine transporter, respectively...

Splenic abscess is one of the rare and potentially life-threatening complications after kidney transplantation. Splenic abscess generally occurs in patients who have immunodeficiency state. It becomes more important with the increased use of immunosuppressed drugs and organ transplantation. The clinical presentation of splenic abscess is insidious, often with constitutional symptoms. Left upper quadrant tenderness is an uncommon sign. Therefore, its diagnosis is difficult and requires a high degree of clinical suspicion...

Staphylococcus aureus (S. aureus) is a major cause of infection in hospitals and communities. Widespread dissemination of multi-drug resistant S. aureus is a serious threat to the health of humans and animals. An anti-virulence strategy has been widely considered as an alternative therapeutic approach. Inhibitors of virulence factors are able to treat S. aureus infections without influencing the growth or viability of bacteria and rarely lead to bacterial resistance. Sortase A (SrtA) is a membrane-associated cysteine transpeptidase that catalyzes up to 25 surface proteins that covalently bind to cell wall peptidoglycans...
