Spinal Arachnoid Web.

Case Presentation: We describe a case of a 57-year-old male with multiple medical comorbidities who presented to the emergency department with a two-week history of upper back pain with associated numbness. Physical exam demonstrated sensory loss in a bilateral third and fourth thoracic dermatome distribution. The diagnosis of spinal arachnoid web was made based on neurological exam and imaging findings.

Application of thrombolytic drugs on clotted blood and bone marrow specimens to generate usable cells for cytogenetic analyses.

Context: Clotted blood and bone marrow specimens account for a large proportion of failed cytogenetic studies. There are no published protocols describing salvage of clotted specimens such that conventional chromosome or fluorescence in situ hybridization (FISH) studies can be performed.

Objective: To evaluate the utility of thrombolytic drugs on clotted blood samples to yield intact cells suitable for cytogenetic analysis.
