RATIONALE: The lower rectal gastrointestinal stromal tumor (GIST) is a rare entity and warrants special attentions because of the considerations of preserving of anal and urinal functions. Neoadjuvant therapy with imatinib mesylate (IM) has achieved great success in GIST, which potentially extends the applications of function-preserving minimally invasive surgical procedures. Transanal endoscopic microsurgery (TEM) is a well-developed minimally invasive technique for benign tumors in lower rectum...

The most common extraintestinal complication of Entamoeba histolytica is amoebic liver abscess (ALA). Hepatic vein and inferior vena cava (IVC) thrombosis are rare but well-documented complications of ALA, typically attributed to mechanical compression and inflammation associated with a large abscess. We present a case of a previously healthy 43-year-old Canadian man presenting with constitutional symptoms and right upper quadrant abdominal pain. He was found to have thrombophlebitis of the IVC, accessory right hepatic vein, and bilateral iliac veins...

INTRODUCTION: Infection of prostate gland following biopsy is common complication. Most common pathogen is E.coli. Since fluorochinolones are commonly prescribed as prophylaxis, infection caused by E.coli leads to complicated infections, especially due to fluoroquinolone-resistant species. The aim of this study was to evaluate the incidence of fluoroquinolone-resistant E.coli species in rectal swabs of patients undergoing prostate biopsy and to define appropriate antimicrobial agent as prostate biopsy prophylaxis...

This is a report of an infant born near term with neonatal stroke and haematuria. Changes were noted on foetal magnetic resonance images, and these persisted postnatally. A routine renal ultrasound scan during follow-up detected haematuria with no associated proteinuria. A likely pathogenic genetic mutation was identified. This case highlights a relatively newly discovered cause for hereditary nephropathy affecting the basement membrane, initially affecting the glomerular but later the renal tubular basement membranes...

A 59-year-old Portuguese Caucasian man with a history of heavy alcohol intake and no significant medical history presented with ascites, weight loss and general malaise. The ascitic fluid analysis showed 921 cells/mm(3) with mononuclear predominance (93.6%), elevated total proteins and a slightly elevated serum-ascites albumin gradient. The abdominal ultrasound confirmed the presence of chronic liver disease with ascites, and additionally on CT there was evidence of peritoneal thickening. On repeat paracentesis, the ascitic fluid analysis showed elevated adenosine deaminase but it was negative for the presence of mycobacteria by Ziehl-Neelsen stain, Löwenstein-Jensen culture and PCR amplification...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a useful and less invasive procedure for the definitive diagnosis of mediastinal and hilar lymph nodes. However, infectious complications can occur after EBUS-TBNA, although they are extremely rare. CASE PRESENTATION: A 66-year-old man with necrotic and swollen lower paratracheal lymph nodes underwent EBUS-TBNA. A mediastinal abscess developed 9 days post-procedure. Surgical drainage and debridement of the abscess were performed along with lymph node biopsy followed by daily washing of the thoracic cavity...
