How can we treat threatened miscarriages?

We have begun using progetogens to reduce the risk of miscarriage. This significantly decreases the rate of miscarriage compared to placebo.

How common are miscarriages? Miscarriages occur in 15 to 20% of pregnancies. A “threatened” miscarriage is defined as any vaginal bleeding (with or without pain) in a pregnant woman with a closed cervix and an otherwise viable fetus inside the uterus.

What is NOT found to help? Bed rest, pelvic rest (nothing in the vagina meaning no sex, douching or tampons), vitamins, uterine relaxants, and administration of beta HCG. Progestogens (medications that mimic progesterones) may help. A meta-analysis of 7 research studies with nearly 700 women showedthat oral administration of progestogens had a lower risk of miscarriage compared to those receiving placebo.

The National Institute for Health and Care Excellence is currently developing a guideline with regard to progestogens and miscarriage. More research is definitely needed.

Interesting nail finding

I was teaching at the residency program this week and had an interesting nail finding in a child. The girl had a rash 2 months before on her hands and feet and then all of her fingernails started peeling. She otherwise was in good health and felt fine.

What was it? It is called onychomadesis. It can happen 1-2 months after hand-foot-mouth viral illness caused by the Coxsackie virus. The nail plate separates from the nail bed. This makes it look like the nails are peeling. Normal nail growth occurs within 1-4 months and will resolve without any assistance.

I’m glad we could put the patient and the parent’s mind to rest. Reassuring them that this was a normal process was all that was needed.

When to potty train?

As a physician of a significant pediatric population, I am often asked questions about potty training… when it goes well, it goes well. When it does not, parents think/talk about it for years.

When to start potty training? More than 2/3 of US children achieve what is considered the cognitive and emotional development necessary for toilet training by 18 to 30 months of age. This also means that as many as 1/3 of children are NOT ready until nearer to age 3 or afterwards.

How do parents assess a child’s readiness? They need to walk, put on and remove clothes, follow simple instructions and have social awareness including an interest in using the toilet. Children may also show awareness of the need to urinate or defecate and discomfort sitting in soiled diapers. Other signs of readiness are asking to wear “big kid” underwear, regular predictable bowel movements and nighttime bowel control, stays dry for 2 hours at a time or during naps.

What if the child can urinate into the toilet, but refuses to defecate in the toilet? This happens in about 20% of children. The causes are many: pain from constipation, fears regarding defecation or using the toilet, local sin irritation. This is more common in children who bgin training after 3 1/2 years of age. First, your physician should rule out organc causes. Once that is done, avoid any advances in training for a few weeks and just observe to identify psychosocial issues causing the child to not want to defecate into the toilet. Some children will only defecate in a diaper or will hide to defecate. These issues will resolve. Rarely, your physician will refer your child to occupation or physical therapist, behavioral therapists or developmental pediatricians. Children with Down syndrome, autism or cerebral palsy may have more issues with toilet training.

I hope this helps.

As an academic family physician, I have taught hundreds of medical students at and resident physicians over my 20+ years of teaching.

The article below is a powerful reminder of each of our vulnerabilities and what we think we are teaching may be different from what the learner learns.

Do Omega-3 fatty acids prevent cardiovascular disease?

Do Omega-3 fatty acids prevent cardiovascular disease?

Omega-3 fatty acids are primarily found in fish oil.  An American Heart Association report suggested that omega-3 supplements may reduce death from coronary heart disease, possibly through a reduction in ischemia-induced sudden cardiac death.  The report found that the omega-e supplements do not reduce the incidence of recurrent nonfatal heart attacks.  The AHA stated that the benefits of taking omega-e supplements may outweigh the risks. 

There was a recent meta-analysis of 79 research studies with a combined 112,000 patients.  This showed that there was no significant benefits with long-chain omega-3 supplements for preventing all-cause mortality or cardiovascular mortality or cardiovascular events or irregular heartbeats or stroke. 

It is possible that omega-3 fatty acids that are found in foods may have different health effects than a capsule because they may replace consumption of less healthy foods (like decreasing saturated fat intake or salt) as well as provide other beneficial nutrients (like selenium, magnesium, calcium).

My advice is to spend your money on better food (fish anyone?!) and not on omega-3 supplements like mackerel, sardines, herring, oysters, salmon, anchovies, AND flax seed.
