What is ORS?

Sodium glucose co-transport system = creates osmotic pull for water

Perfectly

Why is ORS beneficial?

Cheap and avoids need for IV fluids in mild/moderate dehydration = water instantly absorbed in jejunum avoiding most of intestine

What are the six solutions identified by WHO to the most preventable causes of under 5 deaths?

Immediate and exclusive breastfeeding
Skilled attendant for antenatal, birth and postnatal care

Family knowledge of danger signs 
Water, sanitation and hygiene 
Immunisation

Perfectly

How is SDG Goal 3 going to be achieved?

End preventable deaths in newborns and under 5s, end all forms of malnutrition, reduce by 1/3 premature mortality from non-communicable diseases

What are some diseases the SDG goal 3 wants to eliminate and combat?

Eliminate epidemics of AIDS, TB, malaria and neglected tropical diseases Combat hepatitis, water-borne diseases and other communicable diseases

Where are most cases of infant HIV from?

90% from sub-Saharan Africa = most cases due to mother to child transmission

What is the prognosis for children infected with HIV from birth?

25-30% die before age 1 50-60% die aged 3-5 5-25% live beyond 8 years old (long term survivors)

What has been responsible for the reduction in deaths?

ART

How many babies are infected with HIV from birth by their mother without intervention?

Between 15-45%

How is HIV transmitted from mother to child?

During pregnancy, delivery and breastfeeding (40%)

How can mother to child transmission of HIV be prevented?

Maternal lifelong antiretroviral treatment, screen and treat other STDs (especially herpes), infant prophylaxis for 6 weeks

When should children be tested for HIV when their mother is HIV positive?

At birth, 6 weeks, 9 months, 18 months then 6 weeks after mother stops breastfeeding

What infections may an HIV positive child present with?

Recurrent or severe common childhood illnesses Recurrent oral candidiasis not responding to treatment Recurrent severe bacterial infections (meningitis)

What are some signs and symptoms a child may have HIV?

Failure to thrive or growth failure Generalised lymphadenopathy, hepatosplenomegaly Persistent fever, encephalopathy, chronic parotitis PJP, Kaposi sarcoma, TB, lymphocytic interstitial pneumonia

In what circumstances should HIV counselling and testing be offered?

All countries with generalised HIV epidemics All exposed infants at birth Any infant with suspicion of HIV

What are the diagnostic test for HIV in children <18 months old?

Virological PCR for HIV DNA or RNA

What is the diagnostic test for HIV in children >18 months old

Serological rapid antibody test

How can HIV be staged?

Clinical staging = 1-4 Immunological staging = CD4 count Virological staging = viral load

What is given in highly active antiretrovirus therapy (HAART) for HIV?

Two NRTIs plus one NNRTI or protease inhibitor

What are some examples of drugs given in HAART for HIV treatment?

NRTI = abacavir, lamivudine NNRTI = efavirenz for > 3 years old Protease inhibitor = kaletra for < 3 years old

What are some complications of HIV treatment?

Compliance and side effects | Immune reconstitution inflammatory syndrome (IRIS) = NSAIDS

What are some prophylactic HIV treatments?

Co-trimoxazole, routine vaccination

How does TB present?

Chronic cough or fever >2 weeks, night sweats, weight loss, lymphadenopathy

What are the risk factors for TB?

HIV, malnutrition, household contact

What investigations are done for TB?

Acid fast bacilli = low yield in children Interferon-gamma release assays Chest x-ray Mantoux

How is TB treated?

Two months of rifampicin, isoniazid, pyrazinamide +/- ethambutol Then four months of isoniazid and rifampicin

When should treatment of TB be extended for a longer period than normal?

How is TB prevented?

BCG vaccine, pre and post exposure rifampicin

What is the vector for malaria?

Plasmodium parasite is transferred by female anopheles mosquito

What form of malaria is the most severe?

That caused by P.falciparum = can rapidly progress to severe cerebral malaria, seizures and coma

How does malaria present?

Variable = fever, pallor, non-specific malaise

What investigation is done for malaria?

Blood film for microscopy or rapid diagnostic test

What age group has the most malarial deaths?

Under 5s

What is the general treatment for malaria?

Artemisinin-based combination therapy (ACT) for three days

How is severe malaria treated?

IM or IV artesunate until patient can tolerate oral

What should be given in areas of high malaria transmission?

Preventative treatment to all infants alongside routine vaccinations

How can malaria be prevented?

Long lasting insecticide nets (LLINs), pilot projects for malaria vaccine

What are some causes of malnutrition?

Lack of access, poor feeding practices, infection

What are the markers for severe acute malnutrition?

Mid arm circumference < 115mm Weight for height <3SD Oedema of both feet

How can malnutrition patients be managed if they have good appetite and no complications?

As an outpatient

What are some treatments for malnutrition?

Investigate cause, vitamin A, de-worm, make sure vaccinated, ready to use therapeutic food (RUTF)

What are some examples of ready to use therapeutic foods (RUTF)?

Peanut butter, dried milk, vitamins and minerals

What are the four non-communicable diseases that have the highest mortality in adults?

CV diseases, cancer, diabetes, chronic respiratory diseases

What are the four main behavioural risk factors that cause non-communicable diseases in adults?

Tobacco use, harmful use of alcohol, insufficient physical activity, unhealthy diet/obesity

Where do most people with epilepsy live?

In low and middle income countries

What is the most common type of epilepsy?

Secondary epilepsy

Is epilepsy treatable?

Yes = 70% respond to treatment, however 75% of sufferers don't get the treatment they need

Are most deaths due to epilepsy preventable?

Yes = most are due to accidents (drowning, falls, burns, prolonged seizures)

Why do war and conflict lead to disease?

Cause over crowding = lack of food, water and shelter | Break down of health service

What does maternal education determine?

Child health

What is the association between education and child mortality?

Secondary school education decreases the chance of a child dying by 2/3
