development milestone age appropriately except walking, which achieved
at the age of 1 year &8 months of age.
     There is no history suggestive of chronic liver disease or chronic
renal disease. In dietary assessment there is 200Kcal deficiency per day.
     On examination baby has frontal bossing, Harrison sulcus, Rachatic
rosary, widening of wrist & protruded abdomen. On nutritional
assessment there is reveal chronic malnutrition.

     Baby has features suggestive of rickets
     Baby has chronic malnutrition

   Social Problem
      Mother has to stay at hospital with this child. Therefore other
            is with grand mother

     1. Renal rickets
     2. Nutritional rickets
     3. Fanconi syndrome

   Radiograph –upper limb, Lower limb, Chest
         Show frying, & cupping
         Rachitic change in growth plate
     Serum calcium
            10mg/dl -Normal
     Serum electrolyte
              Sodium-138meq/l -Normal
              Potasium-4.6meq/l -Normal
    Blood urea

         Pco2 -28.7mmHg -Low
         Po2 - 89.9mmHg
      Results are compatible with metabolic alkalosis. That may due to
     Urine ward test
         Benedict test –Green
         Urine protein –Nil
      Rickets is the disease condition where failure in mineralization of
bone or osteoid tissue. When mineralization impaired epiphyseal growth
area become disorganized & hypertrophic. Here following clinical
features can be seen.
      Frontal bossing
      Rickety rosary
      Harrison’s sulcus
      Expansion of metaphyses
      Failure to thrive
      Delayed closure of anterior frontanelle
      Delayed dentition
      Bowing of weight bearing bone
This child has above four clinical features with radiological finding like
cupping of the metaphyses of wrist joint & poor mineralization of bone.
So this child is clinically diagnosed as rickets.
      There are many causes for rickets. Those are as follows
    Nutritional rickets
                     Diet low calcium, phosphorus, vitamin D
                      Decreased exposure to sunlight
                   Prolong parental nutrition
   Intestinal malabsorption
   Defective production of 1, 25 dihydroxycholecalciferol
                    Hereditary type 1 vitamin D resistant rickets
                    Familial hypophosphataemic rickets
                    Fanconi syndrome
  Target organ resistant to 1, 25 dihydroxy cholecalciferol
                   Hereditary vitamin D dependant rickets type 2

 When consider this child, she has a history of low calorie intake
.Waterlow classification reveal she has chronic malnutrition. In addition
baby is still breast fed. Breast milk is poor source for these mineral.
Therefore there is high chance to develop Calcium deficiency &
phosphorus deficiency which leads rickets. This baby has enough
exposure to sun light, which is a main source for vitamin D. Therefore
this may be due to a defect in the formation of active vitamin D, which is
help to increase the calcium level in the body. Formation of active Vit D
takes place at liver & kidney. If these organ has defective function it leads
to reduce active Vit D & leads rickets.

      In this child urine ward test reveal Benedict test positive. That
means reducing substances like glucose excrete via urine. That is seen in
Fanconi syndrome. In this condition serum calcium level is normal with
reduce phosphate level. That also sees with child’s report. Therefore urine
sample was sent for the urinary amino acid chromatography to conform
metabolic condition.
       Baby was discharge on one alpha cholecalciferol 0.25 mg/daily

       Apart from the above condition baby has protein energy
malnutrition grade 2. Her height & weight are below the third centile.
Weight deficit is 27.6%.Therefore I did 24 hour dietary survey. It reveal
370Kcal deficit. So I advised to mother stop breast feeding .I hand over
the leaflet to mother about balance diet according to dietician opinion.
        At the discharge there was planed revive the baby at clinic with
USS abdomen & urinary amino acid chromatography reports.
