The isolation of good quality genomic DNA from formalin-fixed, paraffin-embedded tissues is challenging, especially in cases of small tissue specimens. The aim of our study was to evaluate a DNA extraction protocol using formalin-fixed, paraffin-embedded tissues in our laboratory and apply this method to a series of papillary thyroid microcarcinomas (PTMCs). A total of 25 PTMCs and 3 papillary thyroid carcinoma control cases were included in the study. We assessed a DNA extraction protocol on the basis of a precipitation method (MasterPure DNA purification kit, Epicentre), according to the manufacturer's instructions...

Aggressive natural killer (NK)-cell leukemia/lymphoma is a systemic NK-cell neoplasm that preferentially affects Asians with a fulminant clinical course and is almost always associated with Epstein-Barr virus (EBV). The data on EBV-negative aggressive NK-cell leukemia/lymphoma are limited. Here we report a series of three patients (two Caucasians, one African-American) with EBV-negative aggressive NK-cell leukemia/lymphoma from a single institution, including a case diagnosed on post-mortem examination. Similar to EBV-positive aggressive NK-cell leukemia/lymphoma, our patients presented with constitutional symptoms and hepatosplenomegaly, and followed a highly aggressive clinical course...

REVIEW
George Pei Cheung Yang
Laparoscopic repair for ventral and incisional hernias was first reported in the early 1990s. It uses intraperitoneal only mesh placement to achieve a tension-free repair of the hernia. However, in recent years, there has been greater concern about long-term complication involving intraperitoneal mesh placement. Many case reports and case series have found evidence of mesh adhesion, mesh fistulation, and mesh migration into hollow organs including the esophagus, small bowel, and large bowel, resulting in various major acute abdominal events...

OBJECTIVES: Methods of energy delivery for traditional spinal cord stimulation (SCS) systems consist of adjusting programming parameters to affect the total charge delivered per unit time. One high electrical charge delivery method being considered is subthreshold high density (HD) programming. To date, there is limited clinical evidence for the efficacy and safety of paresthesia-free HD programming. The aim of this study was to examine the efficacy and safety of HD programming. MATERIALS AND METHODS: A retrospective review was performed on HD-programmed SCS patients with a minimum of one year follow-up...

Fecal microbiota transplantation (FMT) has evolved from a case report in the medical literature to the basis of major innovations in the treatment of Clostridium difficile infection (CDI) and, potentially, inflammatory bowel disease (IBD). In the clinical setting, FMT was noted to significantly lower the risk of recurrent CDI, likely by increasing microbial diversity and altering the metabolic environment in the intestinal tract of recipients. In parallel, advances in the ability to quantify and characterize microbial communities in fecal samples led to the association of IBD with a state of intestinal dysbiosis...

Retrobulbar injection has been widely practiced as a technique of ocular anesthesia for many decades. Nevertheless, the technique is not free from complications. Vascular occlusion secondary to retrobulbar injection is rare but can be vision threatening. We report a case series of two such patients who presented with poor vision following retrobulbar injection. Fundus showed pale retina with cherry red spot suggestive of central retinal artery occlusion in case 1 and pale disc with sclerosed vessels and multiple superficial hemorrhages suggestive of a combined occlusion of retinal artery and vein in case 2...

Collagen cross-linking is gaining popularity not only for arresting the progression of keratoconus but also other indications including management of corneal infections. In this review article, we analyzed the published literature to understand the level of evidence for its use in corneal ulcer. Photoactivated riboflavin and ultraviolet A light are known to possess antimicrobial properties. The treatment also induces formation of inter- and intra-fibrillar bonds, thereby making the corneal collagen resistant to the action of proteases arresting stromal melt...
