☀️ Vitamin D Deficiency in Children: Hidden in Plain Sight

Even in sunny Malaysia, vitamin D deficiency is common in children and adults.

Why it matters:
Essential for strong bones, growth, and immune health.

Why so common?
Indoor lifestyles
Limited sun exposure
Skin protection & pigmentation factors
Low dietary intake

For growing children who are at risk, vitamin D3 supplements are often required :
Treatment options vary:
Daily oral drops/tablets
Oral sprays
Intermittent high-dose therapy

📌 The right choice depends on the child—age, deficiency level, and compliance all matter.

Always consult your paediatrician or paediatric endocrinologist for the appropriate formulation and dosing.

Petua Ramadan 2

DKA dan Puasa

Mengapa risiko DKA meningkat?
Semasa berpuasa, kanak-kanak dengan diabetes mungkin kurang insulin, tidak makan, atau kurang minum. Tanpa insulin yang mencukupi, badan akan memecahkan lemak dan menghasilkan keton. Keton yang tinggi boleh menyebabkan asid dalam badan meningkat dan komplikasi Diabetes Ketoacidosis (DKA), iaitu keadaan kecemasan yang berbahaya terhadap nyawa.

Apa yang perlu dipantau?
✅ Paras gula darah (lebih kerap)
✅ Paras keton (jika gula tinggi atau anak tidak sihat)
✅ Tanda dehidrasi (mulut kering, kurang kencing)
✅ Tanda bahaya: muntah, sakit perut, pernafasan laju, terlalu letih

👉 Puasa mesti dibatalkan dan dapatkan rawatan segera jika keton positif atau ada gejala.

Why is there a risk of DKA with fasting ?

During fasting, children with diabetes may get too little insulin, miss meals, or become dehydrated. When the body lacks insulin and is dehydrated, it breaks down fat for energy, producing ketones. High ketones lead to high acid, very high levels lead to Diabetic Ketoacidosis (DKA), a serious and life-threatening condition.

What to monitor?
✅ Blood glucose (check more often)
✅ Ketone levels (especially if sugar is high or child feels unwell)
✅ Signs of dehydration (dry mouth, low urine)
✅ Warning symptoms: vomiting, abdominal pain, rapid breathing, extreme tiredness

👉 Break the fast and seek medical help if ketones are positive or symptoms appear.

The youngest child with diabetes Ive treated? A 3 month old baby with a rare form of genetic diabetes known as neonatal diabetes. Happy to share my latest article published in the Sunday Star. "When a baby has diabetes..."

" It is crucial to remember that diabetes in babies under six months of age is almost never type 1. Genetic testing should be considered for all babies below one year old with negative pancreatic antibodies. This is as early diagnosis can completely change a child’s treatment and future, with some forms of neonatal diabetes able to be treated with tablets instead of insulin.
While neonatal diabetes is rare, it is one of the most important diagnoses not to miss.
In a tiny baby fighting DKA, the difference between lifelong insulin and a simple daily tablet may come down to a single gene. That is the miraculous power and science of modern molecular medicine"

When a young infant has diabetes, neonatal diabetes a monogenic form of diabetes must be excluded. Paediatric endocrine consult should be sought and genetic testing done early. This is because some types of neonatal diabetes can respond to oral sulphonylyrea.

In infants with high blood sugar levels, a rare, but treatable, genetic disorder should always be tested for.

Why is chickenpox worse in older kids? 🤔

Chickenpox is usually mild and self-limiting in young children, but older children and adolescents can get it much more severely.
As we grow, the immune response is stronger, which can mean higher fever, more rash, and more inflammation.

Recently, I treated an older adolescent with severe chickenpox who needed acyclovir and hospitalisation for dehydration, while the younger sibling had a much milder illness.

While most children recover well , chickenpox can sometimes lead to complications like skin infections, pneumonia, brain inflammation (encephalitis), and dehydration — especially in babies, teenagers and children with weak immunity (immunocompromised)

💉 The chickenpox vaccine, given after 1 year of age, greatly prevents and reduces the risk of severe disease and complications. Talk to your doctor if its a suitable option for your child. 💙

Panduan Berpuasa bagi Penghidap Diabetes Jenis 1 (T1D)

Kanak-kanak dan remaja yang menghidap diabetes Jenis 1 sebenarnya tidak diwajibkan berpuasa pada bulan Ramadhan. Ini kerana berpuasa boleh membahayakan kesihatan mereka, seperti risiko kencing manis berasid (DKA) atau tahap gula dalam darah yang terlalu rendah (hipoglisemia) jika tidak dipantau dengan betul.

Namun, semakin ramai anak muda di Malaysia yang bersemangat untuk turut serta berpuasa. Jika anda salah seorang daripadanya, sila ikuti langkah keselamatan ini:

• Dapatkan Kaunseling: Berjumpa dengan doktor sebelum Ramadhan untuk bimbingan khas.
• Pendidikan Diabetes: Pastikan anda faham cara menguruskan gula dalam darah semasa berpuasa.
• Pantau Gula Darah: Sentiasa periksa tahap gula (BG) anda dengan kerap sepanjang hari.
• Laraskan Insulin: Tukar dos insulin anda mengikut keperluan dan nasihat pakar.

Pesanan Penting: Dapatkan nasihat daripada doktor anda terlebih dahulu supaya anda boleh berpuasa dengan selamat pada musim ini!

Young people with Type 1 diabetes mellitus are not under compulsion to fast during the holy month of Ramadhan as fasting can pose imminent danger of DKA, and severe hypoglycemia if not monitored safely.

However, we are seeing more and more young children and adolescent in Malaysia who wishes to fast in Ramadhan. These young people with T1D should receive pre-fasting counselling and diabetes education to ensure they can fast safely during Ramadhan.

If you are someone with T1D and wishes to fast, please monitor your BG and adjust insulin as necessary. Get advice from your doctors so you can fast safely during this season!

Why RSV "vaccines" for babies costs more than RSV vaccines for adults

Beyfortus and RSV vaccines for adults are not the same, which is why the price is different.

Beyfortus is actually not a vaccine. It is a monoclonal antibody given to babies to protect them from severe RSV lung infection (bronchiolitis). It works right away by giving babies ready-made protection.

At the moment, there is no RSV vaccine approved for infants. Babies can only be protected using monoclonal antibodies like Beyfortus or if mothers received RSV vaccination during pregnancy.

RSV vaccines for adults work differently. They help the body make its own protection, which is simpler to produce and costs less.

Beyfortus is made specially for newborns and babies below 2 years who are at risk, which is why it costs more. Admnistration is similar to most vaccines via intramuscular injection at the thigh
