INTRODUCTION: Leydig cell tumor constitutes only about 1-3% of testicular neoplasms. There is apparently increased incidence in the last few years; one possible explanation for this phenomenon is the widespread use of ultrasound technology and the subsequent increased early detection of smaller lesions that have not been found in historical series. CASE PRESENTATION: We report a case of Leydig cell tumor of testis in a patient presenting with painless long standing slowly growing left scrotal mass who found to have intrapulmonary nodule and multiple enlarged retroperitoneal lymph nodes on staging work up...

OBJECTIVE/BACKGROUND: Biomarker(s) for prediction of the future progression rate of abdominal aortic aneurysms (AAA) may be useful to stratify the management of individual patients. AAAs are associated with features of systemic inflammation and endothelial dysfunction. Flow mediated dilatation (FMD) of the brachial artery is a recognised non-invasive measurement for endothelial function. We hypothesised that FMD is a potential biomarker of AAA progression and reflects the temporal changes of endothelial function during AAA progression...

INTRODUCTION: The majority of women having planned cesarean section receive spinal anesthesia for the procedure. Typically, spinal opioids are administered during the same time as a component of multimodal analgesia to provide pain relief in the 16-24h period postoperatively. The quadratus lumborum block is a regional analgesic technique that blocks T5-L1 nerve branches and has an evolving role in postoperative analgesia for lower abdominal surgeries and may be a potential alternative to spinal opioids...

CASE: A 54 year old woman with hypothyroidism presented with right flank pain that began acutely one week prior to presentation. She was told initially she had a urinary tract infection and treatment resulted in mild symptomatic improvement. The pain returned and she presented to another Emergency Department (ED); and was told the pain was due to constipation. She returned to the ED the next day when her pain worsened and her labs were notable for WBC of 19,000/uL, BUN/Cr of 28/0.75 mg/dL, AST of 31 U/L, ALT of 92 U/L and total bilirubin of 0...

Regional techniques provides excellent post operative pain relief in pediatric patients. Transversus abdominis plane (TAP) block is a newer regional technique available. Though there is emerging evidence proving the efficacy of TAP blocks, there is limited literature on use of TAP catheters in pediatric patients. TAP catheters were placed in two children following laparotomy with transverse incisions and in both epidural was avoided, with good post operative pain relief. Ultrasound guidance was used in one child, while in the other the catheter was placed under direct vision after dissection of the plane between transversus abdominis and internal oblique...

An elderly male presented for emergent repair of a ruptured abdominal aortic aneurysm. For anticipated volume resuscitation, vasopressor administration, and hemodynamic monitoring, a large-bore central venous catheter was placed in the left internal jugular vein under ultrasound guidance before surgical incision. Initially, there were no readily apparent signs of venous perforation. However, a massive left hemothorax developed because of perforation of the brachiocephalic vein and violation of the pleural space...

BACKGROUND: The potential for an ultrasound-based screening programme for renal cell carcinoma (RCC) to improve survival through early detection has been the subject of much debate. The prevalence of ultrasound-detected asymptomatic RCC is an important first step to establishing whether a screening programme may be feasible. METHODS: A systematic search of MEDLINE and Embase was performed up to March 2016 to identify studies reporting the prevalence of renal masses and RCC...

Renal medullary carcinoma (RMC) is a rare, highly aggressive tumor recognized as an independent pathological entity. African-descent adolescents and young adults with sickle cell hemoglobinopathy are the most affected groups. This rare subtype of renal cell carcinoma has its own morphogenetic and pathological characteristics. The major clinical manifestations include gross hematuria, abdominal or flank pain, and weight loss. The prognosis is very poor, with 95% of cases diagnosed at an advanced stage of the disease...
