One of the most dreaded complications in obstetrics is a stillbirth that is defined as the absence of life upon delivery of the baby. There are approximately 3million stillbirths that occur each year globally and one-half million in the U.S. In developing countries, the most common reasons of stillbirths were prolonged labor, pre-eclampsia and infections whereas in the U.S., the most common causes are abnormal genes, abnormal growth (aka growth restriction) and maternal diseases. According to medical studies, unexplained fetal loss is the most common reason for stillbirths that occur after 28 weeks. Risk factors for stillbirth include women who have infections, abnormal chromosomes, genetic disorders and umbilical cord complications. Race and socioeconomics also play a role. Black women have twice the risk of having a stillbirth as Caucasian women. Smoking and advanced maternal age also poses an increased risk.
Until recently, there are no screening tests available to see if a woman was carrying a baby at risk for stillbirth. However, a medical study presented at a conference reported that stillbirths can now be predicted using Read more »

Not as often as you think, even though Medicare may be willing to pay for it every two years. Via Science Daily:
Now a new study led by Margaret L. Gourlay, MD, MPH of the University of North Carolina at Chapel Hill School of Medicine finds that women aged 67 years and older with normal bone mineral density scores may not need screening again for 10 years.
“If a woman’s bone density at age 67 is very good, then she doesn’t need to be re-screened in two years or three years, because we’re not likely to see much change,” Gourlay said. “Our study found it would take about 16 years for 10 percent of women in the highest bone density ranges to develop osteoporosis. That was longer than we expected, and it’s great news for this group of women,” Gourlay said.
The researchers suggest that for T scores > -1.5, repeat testing needn’t be done for 10 years. Women with T scores between -1.5 and -2.0 can be re-screened in 5 years, and those with T scores below -2.0 can have every other year testing as is done now.
To be honest, I’ve been spacing out bone density testing in woman with good baseline scores for some time, but not knowing how long I can go. This is great information for me and for my patients.

Everybody knows that colonoscopy is the best test to screen for colorectal cancer and that colonoscopies save lives. Everybody may be wrong. Colonoscopy is increasingly viewed as the gold standard for colorectal cancer screening, but its reputation is not based on solid evidence. In reality, it is not yet known for certain whether colonoscopy can help reduce the number of deaths from colorectal cancer. Screening with fecal occult blood testing (FOBT) and flexible sigmoidoscopy are supported by better evidence, but questions remain. It seems our zeal for screening tests has outstripped the evidence.
Statistics show that the life-time risk for an adult American to develop colorectal cancer (CRC) is approximately 6%. Colorectal cancer is the second leading cause of cancer deaths in the United States. In the US there are currently 146,970 new cases and 50,630 deaths each year. Between 1973 and 1995, mortality from CRC declined by 20.5%, and incidence declined by 7.4% in the United States. Read more »
