My
primary responsibilities, as an Associate in Surgery (Neurosurgery)
[Harvard
Appointment], are in the management of a research laboratory
at MGH where I direct the Neurosurgery Surgical Research Laboratory.
I work for Dr Robert L. Martuza, Chief, MGH Neurosurgical Service
(see Research@Neurosurgery)
where I am also the Director, MGH Neurosurgery Information Systems.
In this capacity, I am an
active member of several of standing MGH committees:
MGH Executive Committee
on Research, Subcommittee on Research Facilities (SRF)
MGH Subcommittee on Research
Animal Care (SRAC)
Institutional Animal
Care and Use Committee (IACUC) - Protocol Review Group (PRG)
MGH Unit Safety Officer
Advisory Committee
MGH Web Strategy Committee
- Internet, and Intranet Web Committee
Summary
- Research Activities - Director, Neurosurgery Surgical Research
Laboratories
In the Neurosurgery Surgical
Research Laboratories, there are multiple ongoing basic and preclinical
research projects involving studies of functional neurosurgery,
neuroregeneration & degeneration, cerebral vasospasm, stroke,
neuroimaging, neurotransplantation and gene therapy. These studies
range from basic bench-top assays of components involved in metabolic
and/or pathophysiological pathways, to surgical models of disease
pathways and treatments, to innovative use of new technologies,
to imaging studies (PET, fCT, fMRI) of physiological changes involved
in these disease processes.
In addition to the variety
of research support requirements, I also provide some departmental
wide low level support on PC and MAC computer issues. This also
includes some technical support on high end Unix workstations used
for medical image analysis in support of OR surgical case planning.

Activities - Director, Neurosurgery Information Systems
Neurosurgical Service (Systems Administrator
/ Editor / Webmaster)
I am responsible for the development
of web systems, html and graphics, that are used in support of the
MGH Neurosurgical Service (some of which are listed below). This
includes responsibility for both software and hardware issues, maintenance
of a series of servers (web & database systems), as well as
informational content development.
In addition to the variety of research
support requirements, I also provide some departmental wide low
level support on PC and MAC computer issues. This also includes
some technical support on high end UNIX workstations used for medical
image analysis in support of OR surgical case planning.

The Neurosurgery Surgical Research
Laboratory also provides surgical support facilities for Investigators
conducting studies of interest to the Neurosurgical Service.
Recent examples of studies conducted in the Neurosurgery Surgical
Research Laboratory are:
Albert Lee, M.D.
- Brain cooling. Hypothermia
is the most consistent, robust and broadly applicable
experimental neuroprotective strategy for ischemic brain
injury. A decrease in stroke injury in animal models
occurs with only a 2-3 degree reduction in brain temperature.
Initial clinical reports from Germany indicate that
cerebral hypothermia can be attained by total body cooling,
and is feasible and safe in stroke patients. We wish
to test the ability of hypothermia to block the progression
of ischemic injury as measured by diffusion-weighted
MRI (DWI).
Gilberto Gonzalez, MD,
Ph.D. - Selective laser thrombolysis. The
use of thrombolytic drugs such as urokinase, tissue
plasminogen activator introduces an inherent risk of
brain hemorrhage. There is a known (0.5%) risk in cardiac
thrombolysis, it reached 6% in the American t-PA trial.
In addition, bleeding risk excludes a number of devastated
stroke patients from thrombolytic therapy, especially
post-surgical cases. Laser assisted thrombolysis offers
to improve the access of thrombolytic drug to the clot
by causing microcavitation in the clot. This should
allow recanalization of blocked vessels with lower doses
of thrombolytic drug and lower risk of hemorrhage. Selective
laser assisted thrombolysis has been developed for the
treatment of acute myocardial infarction by applying
pulses of low enough energy and pulse rate to selectively
deposit energy in the clot. Laser energy pulses of short
duration, nanoseconds-microseconds, deposit energy into
the thrombus and begin the ablation process before sufficient
heat diffuses to adjacent tissues, thereby limiting
thermal damage.

I have current experience
with a variety of operating systems: PC (DOS, Windows 3.x, Win95/98/ME,
NT3.51 NT4, NT5, Win2k Professional and Server), some working knowledge
of MAC Os's, and some UNIX (HPUX). and some Linux.
I have experience with a
variety of software packages including: MS Office (95-2000), Adobe
Photoshop, Paradox & FileMaker Databases, a mix of spreadsheet
& word processors, scanning & slide making packages, specialty
netwoking packages, and CDR & PC hardware systems.

If you see a Snake,
kill the Snake. Don't form Snake review committees.
Don't form Snake discussion groups. Kill the Snake.
Don't kill dead
Snakes. Leave them alone, they are dead. Learn from them
but move on. Don't get stuck killing dead Snakes.
Observe & Beware.
Many good opportunities start as Snakes. Coordinate the
discussion to identify which items are Snakes and which
are real opportunities.
