| Sanitation
Lauded as Greatest Medical Milestone |
|
A poll conducted
by the British Medical Journal (BMJ) has named sanitation as the
most important medical milestone since the journal was first published
in 1840. BMJ editors asked its readers to vote on the greatest medical
breakthrough since the journal began 166 years ago as part of a
celebration to mark the journal's redesign. The BMJ selected 15
medical advances and published articles arguing the merits of each
one. With more than 11,000 votes from around the world, sanitation
beat out other medical achievements such as antibiotics, the contraceptive
pill, vaccines, anesthesia and the discovery of DNA.
The recent BMJ
article on sanitation notes that new sewage disposal and water supply
systems in the 1800s revolutionized public health in Europe. Edwin
Chadwick published The Sanitary Conditions of the Labouring Population
in 1842, arguing that there was a desperate need for public health
reform. Chadwick's thesis is credited with originating the idea
of sewage disposal and home sewage piping water. The importance
of the home sanitation innovation was cemented in 1854 when Dr.
John Snow discovered that cholera was a waterborne disease, not
airborne as had previously believed.
Inadequate sanitation
remains a major public health problem around the globe. Highly infectious,
diarrheal diseases attributed to poor sanitation and unsafe water,
such as cholera, continue to affect entire communities in developing
countries. According to the World Health Organization (WHO),
approximately 1.8 million people die every year from diarrheal diseases,
with 90% of those affect being children under the age of five.

| EPA
to Survey Quality of Nation's Lakes |
|
The U.S. Environmental
Protection Agency (EPA) announced it will begin a three year environmental
study investigating on the condition of the nation's lakes, ponds
and reservoirs. The "Survey of the Nation's Lakes" will study
a combined total of 909 water sites as part of a larger effort by
EPA, states and tribes to study the state of U.S. water sources,
including coastal waters, streams, rivers, and wetlands. EPA
will release the results of the study in 2009.
EPA researchers
will examine water samples for turbidity, color, shoreline habitat
conditions, and pathogen indicators with the officially stated goal
of addressing two key questions:
1) What is the
condition of U.S. lakes in terms of trophic state, ecological
health, and recreation?
2) What is the
relative importance of key stressors such as nutrients and pathogens
in the water sources?
Trophic indicators
defined by the study include dissolved oxygen profiles, water chemical
quality, nutrient concentrations and the presence of chlorophyll
a.
EPA last measured
the status of lakes during a period from 1972-1976, when 815 lakes
were evaluated nationwide. According to EPA, the new study will
resample 113 lakes from the earlier survey for comparison.

Flood Water Raises Concerns for Disease Outbreaks in Malaysia |
|
Fears of infectious
disease outbreaks are increasing in Johor, Malaysia in the wake
of heavy December flooding that killed 17 people and forced more
than 100,000 people to evacuate their homes. With flood waters slow
to recede, Malaysian health officials have urged an immediate clean-up
of standing water to avoid outbreaks of illnesses including diarrheal
disease, typhoid, and cholera.
As the displaced
residents begin returning to their flood damaged homes, the Malaysian
government has mobilized work crews to begin disinfection procedures
and promote public education on the importance of personal hygiene
as measures to prevent disease outbreak.
Currently, 375
relief centers operated by the Malaysian government are housing
a total of 115,000 evacuees. The volunteer organization, Mercy Malaysia
is conducting health assessments of evacuees and distributing hygiene
packs throughout the affected region.
The Johor flooding
is reportedly the worst in 100 years.

| Bacteria
in Staph Infections Linked to Pneumonia |
|
Researchers
at Texas A&M Health Science Center Institute of Biosciences and
Technology have discovered that a toxin present in a common staph
infection germ also plays a role in an aggressive pneumonia that
can be fatal within 72 hours. The study was reported in the
January 19 issue of the American Association for the Advancement
of Science's journal, Science.
Staphylococcus
aureus bacteria (S. aureus) is the most common cause of hospital-acquired
infections, potentially leading to inflammation of the heart, toxic-shock
syndrome and meningitis. However, a new strain of S. aureus called
CA-MRSA (community-associated methicillin-resistant Staphylococcus
aureus) causes severe skin and tissue infections in healthy
persons who have not been in the hospital or undergone invasive
medical procedures. In addition to the antibiotic methicillin,
the strain is also resistant to oxacillin, penicillin and amoxicillin.
In the study,
researchers showed that CA-MRSA can cause pneumonia and may create
the deteriorating conditions in which the acquired pneumonia can
cause debilitating illness and possibly death.
According to
the researchers, back-to-basics personal hygiene routines, including
common hand-washing is the best line of defense against infection.
