Netlines
Microbial genomes
- Sometime early in the next century, the
human genome sequence will be completed (see
http://www.hgmp.mrc.ac.uk/Public/human-gen-db.html
for some human genome links). However, just now all the action seems to
be in the field of microbial genomes. The genome of Escherichia
coli has just been completed (see
http://mol.genes.nig.ac.jp/ and
http://www.genetics.wisc.edu) and is
the third bacterial genome to be published, following those of
Haemophilus influenzae and Mycoplasma
genitalium
(http://www.tigr.org/tdb/mdb/mdb.html).
- As many as 100 microbial genomes are likely to
be sequenced in the next few years. Terry Gaasterland's running list
of genomes in progress
(http://www.mcs.anl.gov/home/gaasterl/genomes.html)
already lists 45 bacterial genome projects.
- One astonishing aspect of this subject is the rapidity
and ease with which data on genome sequences are made available to the
general public over the world wide web. In many cases you can do
sequence similarity searches on genomes even before they are completed
- examples include the genomes of Mycobacterium
tuberculosis and Plasmodium falciparum at the
Sanger Centre
(http://www.sanger.ac.uk/pathogens) and
that of Neisseria gonorrhoeae at the University of
Oklahoma
(http://dna1.chem.uoknor.edu:80/gono.html).
- Several other sites offer facilities that put genomic
data into a functional context, including EcoCyc and HinCyC
(http://www.ai.sri.com/ecocyc/ecocyc.html)
and the NCBI
(http://www.ncbi.nlm.nih.gov/Complete_Genomes/).
Human genetics on line
- Although only a small fraction of the
human genome has been sequenced, powerful databases have been developed
to provide information on human genetic disorders. The On-line
Mendelian Inheritance in Man (OMIM) database
(http://www3.ncbi.nlm.nih.gov/Omim/) is
intended for use primarily by doctors and other professionals concerned
with genetic disorders, by genetics researchers, and by advanced
students in science and medicine. All the information you could want is
there on over 8,000 inherited disorders - including details of clinical
and biochemical features, diagnosis, genetics, and animal models,
together with pictures and hypertext references to Medline articles and
sequence information in the Entrez database.
- Along the same lines as OMIM is Genline
(http://www.hslib.washington.edu/genline/),
although as yet it contains a much smaller set of entries.
Seek and ye shall find
- The semi-anarchic nature of the Internet means
that there can never be an up to date, comprehensive index of what is
available on line. However, searching for medical information is made
easier by two indexing sites: in Britain OMNI (Organising Medical
Networked Information) provides a searchable list of sites, with some
commentary, on http://www.omni.ac.uk, while
in the United States the medical matrix plays a similar role on
http://www.slackinc.com/matrix/.
- If it's shareware that you are after, the Higher
Education National Software Archive
(http://www.hensa.ac.uk) provides a well
indexed site full of shareware (although you have to be a British
academic to access it).
- To find out what is being said on the network news
groups, try DejaNews
(http://www.dejanews.com), which stores all
sorts of news group postings, or, to focus on biomedical news groups,
visit the Biosci site
(http://www.bio.net/).
- If you are looking for someone's email address try
the Four11 site (http://www.Four11.com/).
- Finally, if you want to buy a book over the Internet,
visit Amazon on http://www.amazon.com.
Post-traumatic stress disorder
- The US National Center for Post-Traumatic Stress
Disorder
(http://www.dartmouth.edu/dms/ptsd) has
recently launched a web interface
(http://dciswww.dartmouth.edu/cgi-bin/dcis/wdi?&Alexandria.Dartmouth.EDU&51001&PILOTS%20Catalog&s)
to its bibliographic index of the worldwide literature on
post-traumatic stress disorder. The site also features fact sheets
on the condition and links to related material on the Internet.
Medicine and anti-medicine
- While within the medical profession we struggle
to practise evidence based medicine, many outside are turning their
backs on science and conventional medicine. Those wishing to reverse
this trend would do well to visit Brian Wall's HealthWatch page on
http://user.itl.net/~brian/HWATCH.HTML.
HealthWatch is a British based charity which ensures that the
alternative, the complementary, the unsubstantiated, and the plain
silly are all put through the blast furnace of evidence based medicine.
- Sadly, one of the staunchest defenders of science
against anti-science, Carl Sagan, died at the end of last year after a
long struggle with myelodysplasia
(http://www.sciam.com/explorations/010697sagan/010697explorations.html).
Sagan was author of the best selling science book of all time,
Cosmos, and, most recently, produced a defence of
science in his Demon-Haunted World: Science As a Candle in the
Dark
(http://www.amazon.com/exec/obidos/ISBN=1561006491/7154-8200924-333098).
For a review of Sagan's life and work, visit Michael Rapp's
unofficial Carl Sagan web site on
http://wwwvms.utexas.edu/~mrapp/sagan/toc.html.
Trauma Moulage
- Trauma Moulage is an interactive educational web
site
(http://www.trauma.org/resus/moulage/moulage.html)
in which you are a casualty department doctor who must assess and treat
an injured patient. It's not easy - I killed the patient several times
over, so I had better stick to laboratory medicine. If, like me, you
had never come across the word "moulage" before, you can look it up
in the online Webster's dictionary on
http://gs213.sp.cs.cmu.edu/prog/webster?moulage.

getting connected in the ABC of Medical Computing
(eds: Nicholas Lee and Andrew Millman, BMJ Publishing),
which has Mark Pallen's Guide to the Internet as a
supplement.
