If you would like some additional background about writing abstracts, we have found a very good source at the website of the American College of Physicians:  There you will find suggestions on determining whether your idea merits and abstract presentation by posing questions such as: Is this experience useful? Did we learn something from it? Does it cover an unusual aspect of an illness or suggest a novel method of treatment?  There's much more included in the ACP link to help you compose your abstract within the parameters of introduction/background, materials/methods, results and summary/conclusions.

Remember to take your time in writing your abstract; then take a day off. Share it with your colleagues. Often you will receive good suggestions in refining your presentation. When you come back to draft your final version, you will have a fresh perspective.


Characteristics of the headache associated with acute carbon monoxide poisoning
Hampson NB, Hampson LA

Introduction / Background:  Headache is the most commonly reported symptom in acute carbon monoxide (CO) poisoning.  It is often described as throbbing and diffuse, however, a systematic characterization of CO-associated headache has never been published.  This study examines the characteristics of CO-associated headache to determine whether any typical pattern exists which might prove useful in the diagnosis of CO exposure.

Materials and Methods: 
Patients referred for hyperbaric oxygen (HBO2) treatment of acute CO poisoning were asked whether headache was part of their symptom complex.  When present, specific details about the nature of the headache were collected from 100 consecutive patients through use of a standardized questionnaire.

Information on acute CO-associated headache was collected from 34 female and 66 male patients with mean carboxyhemoglobin (COHb) 21.3+9.3%.  The most common sources of CO were motor vehicles (31), forklifts (23), or furnaces (11).  Poisonings were accidental in 81%.  The most common location for pain was frontal (66%), although more than one location was involved in 58%.  Nature of the pain at any time during its course was dull in 72% and sharp in 36%.   Headache was throbbing in 41%.  Pain was continuous in 74% and intermittent in 16%.   Peak intensity of pain did not correlate with COHb level.   Symptoms commonly associated with headache included dizziness, lightheadedness, weakness, and nausea.  Headache improved prior to HBO2 treatment in 72%, resolving entirely in 21%.  Of those with residual headache, pain improved with HBO2 in 97%, resolving entirely in 44%.

Summary / Conclusions: 
The headache accompanying acute CO poisoning is extremely variable in nature.   "Classic" throbbing diffuse headaches were rarely described by patients.  There are no patterns which can be considered characteristic to aid in the diagnosis of CO-induced headache.  Similarly, no trait was identified which might allow elimination of CO poisoning from the differential diagnosis of headache.

Serum S-100b as a marker of neurological events in goats following direct decompression in a simulated disabled submarine scenario 
Jurd KM, Parmar K, Seddon FM,  Loveman GAM, Blogg SL, Thacker JC, Stansfield MRD, White MG, Hunt BJ.

Introducation / Background:
S100b is a glial protein used as a marker of cerebral damage in a number of clinical situations. Neurological decompression illness (DCI) is a major risk following rapid decompression to the surface in a disabled submarine (DISSUB) scenario if recompression facilities are unavailable. The aim of this study was to investigate levels of S-100b in goats under simulated DISSUB conditions where neurological DCI may occur.

Materials and Methods:
Adult female or castrated male goats (35-75 kg) underwent dry chamber air saturation between 55 and 85 fsw for 24 h followed by rapid decompression at 0.9 bar/min (n=37). Gross neurological involvement was determined by clinical assessment and post mortem examination.  Venous blood samples were taken pre-dive and at 5, 30, 60, 90, 120, 180 and 240 mins post surfacing.  S-100b was measured in serial samples by immunoluminometric assay.

Neurological DCI was mainly evident in the goats which had undergone the deeper profiles.  A greater percentage of animals undergoing these deeper profiles also had increased levels of S-100b compared to pre-dive values. The percentage of animals at each depth with raised S100b increased from 0% at 55 fsw to 100% at 85 fsw.  Increases in levels of S100b were evident at 5 or 30 mins in most cases, with levels continuing to rise for at least 120 mins.

Summary / Conclusions: This study demonstrates that S100b is raised in goats following "rapid decompression" from air saturation at depths below 55 fsw.  S100b may be useful as a marker of cerebral events in neurological DCI.

Hyperbaric oxygen treatment of decompression sickness: case reports from Louisiana State University Undersea and Hyperbaric Medicine Fellowship Program
Shamitko G, Hickey B, Pavelites J, Murphy-Lavoie H, LeGros TL
LSU Department of Hyperbaric Medicine, University Medical Center and West Jefferson Medical Center

Case Description:
The risk of decompression illness (DCI) is sometimes minimized by recreational diving groups. Decompression illness is an omnipresent concern for those subjected to higher-than-atmospheric pressures. This includes both recreational and commercial underwater diving, as well as those receiving hyperbaric oxygen (HBO2) therapy for wound healing. Symptoms can range from minor skin or joint findings to severe paralysis, spinal cord injury, pulmonary edema, and death. The authors present a series of five case reports outlining recent decompression injury experiences treated at the LSU post-graduate medical training program in Undersea and Hyperbaric Medicine. 

Five emergent decompression injuries treated at WJMC were summarized by treating LSU UHM Fellows and reviewed by attending physicians. 

Five cases of decompression illness are presented, each with varying degrees of neurologic disability.

Cases 1 and 2 were injured recreational divers in Mexico, who were diving “safe profiles” and sustained significant paralysis and mental status changes. After delayed presentation for treatment at West Jefferson Medical Center these injuries resolved. 

Case 3 highlights a potential iatrogenic injury involving unilateral blindness during routine wound treatment with hyperbaric oxygen therapy. Blindness resolved after continued therapy with hyperbaric oxygen therapy. 

Case 4 is a recreational diver from Zanzibar with a previously unknown pulmonary bleb who was injured during a routine dive, with delayed resolution after treatment. 

Case 5 is a local “hell diver” spear fisherman, who routinely practices unsafe diving profiles. He was injured after exceeding decompression limits but recovered fully after prompt treatment.

The wide variety of serious decompression illness presented here does not support the widely advertised assertion that “diving is as safe as bowling.” Four of five cases in this presentation were “undeserved” (unexplained) hits and underscores the need for better preventive measures and continued research into DCI.
