MMR vaccine and Fever
All babies need to receive MMR vaccine at 12 months old. This is a combination vaccine for Measles, Mumps and Rubella. Normally, the post vaccination fever occurs on the first 2 days after vaccination. However, this particulat vaccine cause fever from day 7 to day 12 after vaccination. Although this only occurs in 5-15% of cases, the parents need to know this statistic so as not to get worry should the fever does occur.

Dengue Outbreak Areas in Penang -- update on 20 September 2010
I attended a dengue seminar organised by Penang State Health Department on last Sunday. There are lectures from public health (vector unit) and infectious disease consultants (adult and children medicine). The participants are doctors from private practice.
I benefited from the lectures and impressed on the heated discussion during the Q & A session. The doctors are really concerned with the dengue outbreak in Penang.

- There are already 4 dengue deaths this year, compared to only 1 last year.
- The dengue vaccine is coming soon (I have heard it from the medical student days!!!)
- The WHO has made the classification easier and more practical to doctors.

Protruded belly button -- Umbilical hernia
You may notice some babies with the following condition, especially in a premature baby or young infant:
This is called umbilical hernia. It occurs because the two sides of the abdomimal wall muscles are still not adhered completely, thus leaving a space for part of the tummy contents to protrude out (image).
Generally, it does not cause problems and resolved by one year old. Should the condition persisted until school going age, then we hae to do something to avoid teasing in school. This involves a very minor surgey as illustrated below.
There are some myths about this condition, among them are described below:

There are some myths about this condition, among them are described below:
- This create an entry point for the "wind" to enter -- this is not true as the covered skin is intact, thus leaving no door/ window to enter =)
- This can be resolved by occluding the bellybutton with a 50 cents coin -- this is not necessary as the condition resolved when the underlying muscle layers adhered completely. As the condition usually resolves spontaneously, making this grandmother's ritual appears to work.

Influenza Vaccine -- does my baby need it?
The Influenza A (H1N1) pandemic in 2009 caused great concerns among the caring parents. As the saying goes "prevention is better than cure", we are fortunate to have influenza vaccine to combat this common, and potentially dreadful infection.
The American Academy of Pediatrics (AAP), in response to this development, has updated its recommendation for influenza vaccine.

The American Academy of Pediatrics (AAP), in response to this development, has updated its recommendation for influenza vaccine.
Recommendations for Prevention and Control of Influenza in Children, 2010-2011
- Children younger than 6 months are too young to receive influenza vaccine.
- Only 1 dose is needed for children at least 9 years old.
- Children younger than 9 years require at least 2 doses of 2009 pandemic H1N1 vaccine. They will need 2 doses of seasonal influenza vaccine this year if they did not receive the H1N1 vaccine during last year's influenza season.
- Children younger than 9 years who have never before received the seasonal influenza vaccine will require 2 doses.
- Children younger than 9 years who received seasonal influenza vaccine before the 2009-2010 influenza season need only 1 dose this year if they received at least 1 dose of the H1N1 vaccine last year, but they need 2 doses this year if they did not receive at least 1 dose of the H1N1 vaccine last year.
- Children younger than 9 years who received seasonal influenza vaccine for the first time last year, but who only received 1 dose, require 2 doses this year.
- For children younger than 9 years who received influenza vaccine last year, but for whom it cannot be determined whether it was a seasonal influenza vaccine or the H1N1 influenza vaccine, 2 doses are recommended this year.
- For all children who require 2 doses, the second dose should be administered at least 4 weeks after the first dose.

A 2 year old girl had blood in the stool
A close friend sent me this picture (no consent given by the owner as she is only 2 years old!):
The father preferred to wait and see. I agreed.
P/S I enjoy discussion with the care-takers regarding treatment to the baby. They understand the baby condition, agree on the treatment plan and thus unload their unnecessary anxiety.
A 2 year-old girl had blood in the stool for the past one day. She passed motion five times already. She had low grade fever of 37.8 degree Celsius. She was otherwise well, active and not in pain.
I told the father if she was less than one year old, I would definitely start antibiotic. This is because there is higher risk of severe disease in this group of small infants. As she is two years old and appeared well, I offered 2 choices:
- Wait and see -- as there is possibility of spontaneous resolution of symptoms
- Antibiotic therapy -- as this can kill the causative bacteria, reduce duration of illness and reduce transmission risks. The following article may be helpful:

Rotavirus
Rotavirus Vaccine Effective in Preventing Hospitalizations
TUESDAY, Aug. 24 (HealthDay News) -- High three-dose coverage with a universal infant pentavalent rotavirus vaccine (RV5) is effective in preventing rotavirus and non-rotavirus acute gastroenteritis (AGE) hospitalizations in vaccinated children and older individuals who are unvaccinated, according to a study published online Aug. 23 in Pediatrics.
(read here for full text).
Rotavirus image
- Rotavirus is a virus that infects the gastrointestinal tract.
- Nearly every child worldwide will suffer from at least one rotavirus infection before their fifth birthday (Parashar UD et al. Emerg Infect Dis 2003;9565-72). In Malaysia, the leading cause of diarrhoeal hospitalizations among children is due to rotavirus (Bresee JS et al. Emerg Infect Dis 2004;10:988-95). 38% of hospitalizations for diarrhoea in children younger than 5 years old are caused by rotavirus (Hung LC et al. Int J Infect Dis 2006;10:470-4). So, this is a common disease.
- Rotavirus infection can cause acute gastroenteritis. The baby will suffer from diarrhoea, vomiting, fever and abdominal pain. The most dreadful complication is dehydration (loss of fluid and electrolytes), which may lead to organ failure and death if left untreated. So, this can be a serious diease.
- There are currently 2 types of Rotavirus vaccines, Rotarix and Rotateq. To take Rotarix as an example, it can prevent up to 96% of severe rotavirus gastroenteritis and 100% of hospitalization due to rotavirus gastroenteritis (Vesikari T et al. Human Rotavirus vaccine Rotarix is highly eficacious in Europe. Presented at 24th ESPID, Basel, Switzerland, 3-5 May 2006). So, this is effective.
- One of the concerns with rotavirus vaccines is their association with the risk of intussuception. Rotarix has been extensively studied in worldwide clinical trials with more than 60,000 infants. Results showed that with Rotarix, there is no increased risk of intussuception (Ruiz-Palacios GM et al. N Engl J Med 2006;354:11-22). So, it is safe.
- The total dose of rotavirus vaccines are 2 doses (Rotarix) or 3 doses (Rotateq). There is no much difference in the cost, about RM 300 in total. A study conducted in Malaysia reported the cost of treating a baby with gastroenteritis in Malaysia is RM 650. So, the cost is acceptable.
- Preventing a common disease in Malaysia.
- Preventing a potentially serious disease in Malaysia.
- A safe vaccine.
- An effective vaccine.
- A cost-effective vaccine.
