SIDS

Blood samples from infants who died of Sudden Infant Death Syndrome (SIDS) had high levels of serotonin, a chemical that carries signals along and between nerves, according to a study funded in part by the National Institutes of Health. The finding raises the possibility that a test could be developed to distinguish SIDS cases from other causes of sleep-related, unexpected infant death. The study, led by Robin L. Haynes, Ph.D., of Boston Children’s Hospital and Harvard Medical School, appears in the Proceedings of the National Academy of Sciences. NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) provided funding for the work.

SIDS is the sudden death of an infant under one year of age that remains unexplained after a complete autopsy and death scene investigation. In the current study, researchers reported that 31 percent of SIDS infants (19 of 61) had elevated blood levels of serotonin. In previous studies, the researchers reported multiple serotonin-related brain abnormalities in SIDS cases, including a decrease in serotonin in regions involved in breathing, heart rate patterns, blood pressure, temperature regulation, and arousal during sleep.

Taken together, the researchers wrote, the findings suggest that an abnormality in serotonin metabolism could indicate an underlying vulnerability that increases SIDS risk and that testing blood samples for serotonin could distinguish certain SIDS cases from other infant deaths. However, they caution that more research is needed.

Herniated Discs

What are symptoms of a herniated disc?

The symptoms of a herniated disc depend on the exact level of the spine where the disc herniation occurs and whether or not nerve tissue is being irritated. A disc herniation may not cause any symptoms. However, disc herniation can cause local pain at the level of the spine affected.

If the disc herniation is large enough, the disc tissue can press on the adjacent spinal nerves that exit the spine at the level of the disc herniation. This can cause shooting pain in the distribution of that nerve and usually occurs on one side of the body and is referred to as sciatica. For example, a disc herniation at the level between the fourth and fifth lumbar vertebrae of the low back can cause a shooting pain down the buttock into the back of the thigh and down the leg. Sometimes this is associated with numbness, weakness, and tingling in the leg. The pain often is worsened upon standing and decreases with lying down. This is often referred to as a “pinched nerve.”

If the disc herniation occurs in the cervical spine, the pain may shoot down one arm and cause a stiff neck or muscle spasm in the neck.

If the disc herniation is extremely large, it can press on spinal nerves on both sides of the body. This can result in severe pain down one or both lower extremities. There can be marked muscle weakness of the lower extremities and even incontinence of bowel and bladder. This complication is medically referred to as cauda equina syndrome.
