Delayed Multiple Intracerebral Hemorrhage After Burr Hole Drainage of Chronic Subdural Hematoma During Failure of Warfarin Resumption in Atrial Fibrillation.

Many elderly people take warfarin due to underlying disease. Warfarin is a risk factor for developing chronic subdural hematomas and other intracranial hematomas. Our patient was on chronic warfarin treatment for longstanding atrial fibrillation and underwent burr hole trephination due to chronic subdural hematoma.

Cryopreservation and its clinical applications.

Cryopreservation is a process that preserves organelles, cells, tissues, or any other biological constructs by cooling the samples to very low temperatures. The responses of living cells to ice formation are of theoretical interest and practical relevance. Stem cells and other viable tissues, which have great potential for use in basic research as well as for many medical applications, cannot be stored with simple cooling or freezing for a long time because ice crystal formation, osmotic shock, and membrane damage during freezing and thawing will cause cell death.

A prospective, randomized trial comparing 25-gauge and 22-gauge needles for endoscopic ultrasound-guided fine needle aspiration of pancreatic masses.

Objectives: Endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) is widely performed for pancreatic masses. The 25-gauge needle (25G) might be easier to be manipulated and expected to be associated with fewer complications since it is thinner and more flexible than the 22-gauge needle (22G) although obtaining adequate specimens is questioned. In this randomized trial, the authors tried to compare prospectively 25G and 22G in diagnostic accuracy, manipulability from the operator's viewpoint and procedure-related complications.

A prospective comparison of liquid-based cytology and traditional smear cytology in pancreatic endoscopic ultrasound-guided fine needle aspiration.

Objective: To compare results of liquid-based cytology (LBC) and the conventional smear method (SMEAR) when performing endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for lesions of suspected pancreatic malignancy without an on-site cytopathologist.

Study Design: Fifty-eight patients were prospectively enrolled between July and December 2009. Aspirates obtained from the first needle pass were randomized either to SMEAR or LBC.

Superior long-term outcomes after surgery in child-pugh class a patients with single small hepatocellular carcinoma compared to radiofrequency ablation.

Background And Aims: There are insufficient data comparing long-term prognoses after radiofrequency ablation (RFA) and surgery.

Methods: We compared the baseline characteristics and survival rates of patients (single, ≤3 cm, and Child-Pugh class A) treated surgically (n = 215) and with RFA (n = 255) from January 2000 to December 2007 at our institution.

Results: The surgery group was characterized by younger age, higher prevalence of HBsAg, less cirrhosis, and an increased chance of Child-Pugh score of 5 and CLIP score of 1, compared to the RFA group.

Risk factors associated with the postoperative recurrence of intraductal papillary mucinous neoplasms of the pancreas.

Objectives: The risk factors correlated with the post-operative recurrence of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are not well established. The aim was to determine the risk factors of recurrence.

Methods: We reviewed retrospectively the differences of clinicopathologic features between the recurrence and nonrecurrence groups of patients with IPMN who underwent surgical resection and analyzed the recurrence-related factors.

Composite marginal zone B cell lymphoma and enteropathy-type T cell lymphoma of the stomach: a case report.

We describe a 64-year-old patient with gastric synchronous extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue and enteropathy-type T cell lymphoma. The simultaneous occurrence of mucosa-associated lymphoid tissue lymphoma and enteropathy-type T cell lymphoma is exceptional and has never been reported. We discuss the possible pathogenetic relationship between the two neoplasms.
