National Library of Medicine, world's largest medical library, was a shelf of books in Surgeon General office in 1818

National Library of Medicine, the largest medical library in the world, started in 1818 as a shelf of books the office of the Surgeon General

The National Library of Medicine, the largest medical library in the world, began in 1818 as the US Army Medical Library, in Washington, DC, essentially a shelf of books in the office of Joseph Lovell, then Surgeon General and the head of the Army Medical Department. By the time of the Civil War the book collection consisted of about 2000 volumes and, no longer fitting in the office, was moved to a bank building.

The library, then as now, was constantly running out of space.

In 1962, the library would move to a large new building in Bethesda. There were more than 50 miles of underground bookshelves, and a roof in the shape of a hyperbolic paraboloid. The roof was intended to collapse in the event of an atom bomb, thus protecting the books, if not, perhaps, the librarians.

By 1972, librarians used MEDLINE searches about 140 000 times; today, the annual number of searches of its descendent, MEDLINE/PubMed, is over 2 billion.

Doctor’s Salaries Are Not the Big Cost - NYTimes http://buff.ly/QWe2lx -- "There is a startling secret behind America’s health care hierarchy: Physicians, the most highly trained members in the industry’s work force, are on average right in the middle of the compensation pack. That is because the biggest bucks are currently earned not through the delivery of care, but from overseeing the business of medicine.

The base pay of insurance executives, hospital executives and even hospital administrators often far outstrips doctors’ salaries: $584,000 on average for an insurance chief executive officer, $386,000 for a hospital C.E.O. and $237,000 for a hospital administrator, compared with $306,000 for a surgeon and $185,000 for a general doctor.

Among doctors, there is growing frustration over the army of businesspeople around them and the impact of administrative costs, which are reflected in inflated charges for medical services."

Pancreatic Cancer - 2014 update from Am Fam Physician

Pancreatic cancer remains the fourth leading cause of cancer-related deaths in the United States.

Risk factors include:

- family history
- smoking
- chronic pancreatitis
- obesity
- diabetes mellitus
- heavy alcohol use
- possible dietary factors

Symptoms

Because more than two-thirds of adenocarcinomas occur in the head of the pancreas, abdominal pain, jaundice, pruritus, dark urine, and acholic stools may be presenting symptoms.

Diagnosis

In symptomatic patients, the serum tumor marker cancer antigen 19-9 can be used to confirm the diagnosis and to predict prognosis and recurrence after resection.

Pancreas protocol computed tomography is considered standard for the diagnosis and staging of pancreatic cancer.

Treatment

Surgery


Although surgical resection is the only potentially curative treatment for pancreatic ductal adenocarcinomas, less than 20% of surgical candidates survive five years. The decision on resectability requires multidisciplinary consultation. Pancreatic resections should be performed at institutions that complete at least 15 of the surgeries annually.

Chemotherapy

Postoperatively, use of gemcitabine or fluorouracil/leucovorin as adjuvant chemotherapy improves overall survival by several months. However, more than 80% of patients present with disease that is not surgically resectable. For patients with locally advanced or metastatic disease, chemoradiotherapy with gemcitabine or irinotecan provides clinical benefit and modest survival improvement.

Palliative care

Palliation should address pain control, biliary and gastric outlet obstruction, malnutrition, thromboembolic disease, and depression.
