At the age of 6 months, children can begin to be weaned off breastmilk and formula feeds. One healthy and inexpensive way to do this is through infant led weaning as opposed to the conventional spoon feeding method. Children are able to enjoy a variety of soft finger foods even before they grow teeth, so all food does not need to be pureed or sweet. Children should however not be given cow’s milk until the age of 1 year.

CMPI ( cow’s milk protein intolerance) is an immunological reaction to one or more of the many proteins found in cow’s milk. It may be IgE mediated or non-IgE mediated. The prominent signs and symptoms include sneezing, rhinorrhoea, coughing, wheezing, oral angioedema, oral itching, diarrhoea, vomiting, and bloody stools. Steatorrhea is not a recognized feature of CMPI.

The management of cystic fibrosis requires a multidisciplinary approach, starting with a planned diet.The critical points of this management approach are:Chest physiotherapy and postural drainage – the parents are usually taught to do this.Deep breathing exercises,High calorie, high fat intake with vitamin supplementation.Pancreatic enzyme supplements with meals.Heart-lung transplantation would be the definitive treatment.Note: Previously, a high-calorie, low-fat diet was recommended to reduce steatorrhea. However, it is no longer the desired approach.

Human breast milk composition changes with the progressive age of the infant. Breastmilk produced for a preterm baby often has a higher caloric content than breastmilk for a term baby. After the production of colostrum in the first days of life, the milk continues to mature. by week 4-6 milk can be considered fully mature. The average calories found in mature breastmilk are about 70kcal/100ml

This is probably a case of protein-induced allergic proctitis, due to dietary protein transmitted through the mother to the breast-fed child. The mother should go on a milk-free and soya-free diet but continue to breast-feed.

Malabsorption of fat-soluble vitamins is likely in most people with Cystic Fibrosis (CF).Factors that may contribute to fat-soluble vitamin deficiencies in CF include:- Fat maldigestion and malabsorption as a consequence of pancreatic insufficiency and bile salt deficiency.- Fat maldigestion and malabsorption due to suboptimal PERT or poor adherence to PERT especially with vitamin replacement therapy.- Poor dietary intake due to anorexia or poor dietary sources of vitamins.- Poor adherence to prescribed fat-soluble vitamin supplementation.- Inappropriate vitamin supplementation regimens.- Increased utilisation and reduced bioavailability.- Short gut syndrome due to previous bowel resection.- CF-related liver disease.- Chronic antibiotic use.Vitamin A is a fat-soluble vitamin that plays a role in the eye (dark adaptation), skin, respiratory and immune systems. Vitamin A deficiency may cause night blindness and can proceed to xerophthalmia in CF.Severe vitamin D deficiency causes rickets in children and Osteomalacia in adults.Vitamin E acts as an antioxidant reducing the effects of free radicals produced by infection and chronic inflammation, thus helping to protect cell membranes from oxidative damage.Vitamin E deficiency has been associated with haemolytic anaemia in infants and may cause ataxia, neuromuscular degeneration and compromised cognitive function. Oxidative stress is enhanced in CF due to chronic respiratory inflammation.Vitamin K is important for blood coagulation and bone health.

Iron deficiency anaemia has the following laboratory characteristics: low haemoglobin, a low serum iron, a low serum ferritin, a low transferrin saturation, and a high total iron-binding capacity.

Breath-holding spells are usually caused by either a change in the child’s breathing or a slowing of the heart rate. In some children, breath-holding spells may be related to iron deficiency anaemia, a condition in which the body doesn’t produce a normal number of red blood cells. Conclusion: Not only Iron deficiency anaemia but also iron deficiency alone without anaemia is associated with a risk of high-frequency cyanotic breath holding spells. Iron therapy results in reduction in spells’ frequency which was correlated with increasing ferritin and iron levels.

The next step in the management of this patient is starting a normal saline fluid bolus, following which we should send samples for blood culture, lactate and C-reactive protein. The patient is probably a case of anorexia nervosa (AN).Note:Children with AN are at higher risk of developing infections, and this needs to be considered in this case. Patients with AN may not respond in the usual fashion to sepsis as they may not mount a fever in response to infection. Hypoglycaemia (especially when severe or persistent despite correction) should raise the alarm for an infection as should tachycardia and cool peripheries. Children with severe AN are more likely to be bradycardic. Therefore, a tachycardia should cause the clinician to consider that another process is going on.Other options:- Correcting electrolyte abnormalities is, of course, very important. However, while these are awaited, one needs to consider that this patient is septic and managed accordingly. Children with anorexia nervosa (AN) may have a whole host of electrolyte abnormalities, some of which can be treated with oral or nutritional supplementation although sometimes intravenous correction is required. Electrolytes need to be checked frequently during admission because of the risk of refeeding syndrome, and dietetic input is required to advise on appropriate starting intake.- While maintenance fluids like dextrose are likely to be needed in this case, consideration needs to be given to the underlying cause of the hypoglycaemia. As the sugar has come up following a glucose bolus, a 10% dextrose infusion would be excessive.- An ECG should form a part of any assessment of a child with AN. In this case, it would not be the first thing| however, as part of the acute management of this child, cardiac monitoring should be commenced. One would usually expect a child with AN to be bradycardic so a tachycardia should raise suspicion that another process is going on.- Dietary input will be vital for this child’s ongoing management. However, their acute issues take precedence in this case. Nevertheless, a dietician should be informed and involved from an early stage.

Scurvy is a condition caused by a dietary deficiency of vitamin C, also known as ascorbic acid. Humans are unable to synthesize vitamin C, therefore the quantity of it that the body needs has to come from the diet. The presence of an adequate quantity of vitamin C is required for normal collagen synthesis. In scurvy bleeding tendency is due to capillary fragility and not coagulation defects, therefore blood tests are normal.

Buckwheat is not wheat. It’s a seed rather than a grain, which means it’s gluten-free and safe for people with celiac disease and non-celiac gluten sensitivity. It is an excellent source of fibre and nutrients.

According to NICE guidelines:Do not offer lithium to women who are planning a pregnancy or pregnant, unless antipsychotic medication has not been effective.If antipsychotic medication has not been effective and lithium is offered to a woman who is planning a pregnancy or pregnant, ensure:the woman knows that there is a risk of fetal heart malformations when lithium is taken in the first trimester, but the size of the risk is uncertain. Lithium levels may be high in breast milk with a risk of toxicity for the baby.If a woman taking lithium becomes pregnant, consider stopping the drug gradually over 4 weeks if she is well. Explain to her that:stopping the medication may not remove the risk of fetal heart malformations and there is a risk of relapse, particularly in the postnatal period, if she has bipolar disorder.If a woman taking lithium becomes pregnant and is not well or is at high risk of relapse, consider:switching gradually to an antipsychotic or stopping lithium and restarting it in the second trimester (if the woman is not planning to breastfeed and her symptoms have responded better to lithium than to other drugs in the past) or continuing with lithium if she is at high risk of relapse and an antipsychotic is unlikely to be effective. If a woman continues taking lithium during pregnancy:- check plasma lithium levels every 4 weeks, then weekly from the 36th week. Adjust the dose to keep plasma lithium levels in the woman’s therapeutic range- ensure the woman maintains an adequate fluid balance- ensure the woman gives birth in the hospital- ensure monitoring by the obstetric team when labour starts, including checking plasma lithium levels and fluid balance because of the risk of dehydration and lithium toxicity- stop lithium during labour and check plasma lithium levels 12 hours after her last dose.

The general target of weight gain in the neonatal intensive care unit is to replicate the intrauterine growth in the third trimester, which equates to the daily weight gain of nearly 15 g/kg/day with infants receiving 120 kcal/kg/day

The clinical scenario presented is highly suggestive of vitamin C deficiency (Scurvy).Vitamin C is found in citrus fruits, tomatoes, potatoes, Brussel sprouts, cauliflower, broccoli, cabbage and spinach. Deficiency leads to impaired collagen synthesis and disordered connective tissue. Scurvy is associated with severe malnutrition as well as drug and alcohol abuse, and those living in poverty with limited access to fruits and vegetables.Symptoms and signs include:- Follicular hyperkeratosis and perifollicular haemorrhage- Ecchymosis- Gingivitis with bleeding and receding gums- Sjogren’s syndrome- Arthralgia- Oedema- Impaired wound healing- Generalised symptoms such as weakness, malaise, anorexia and depression

The average amount of energy required by a well preterm baby in a thermo-neutral environment is 50/kcal/kg to maintain essential body functions while it takes about 70 kcal/kg/day for optimal growth. It is important to ensure that enough proteins are given per calorie to limit catabolism and promote cell building. Caloric need usually increases when the baby is ill.

Mature human breast milk is nutrient and enzyme rich, optimal for human infants. The average calorie requirement for a one month old infant is about 100kcal/kg/day. Lactose, the most abundant carbohydrate, is beneficial for the baby’s developing gastro intestinal system. The proteins in mature milk are mostly whey (as compared to a high proportion of casein in cows milk), which digests easily. Other proteins found in breast milk include immunoglobulin, lysozyme, lactoferrin and lactalbumin. In terms of micronutrients, while Vitamin K levels are low in breast milk, Vitamin A, C and E are found in higher concentrations than in cow’s milk.

Vitamin A is a fat-soluble compound occurring in various forms. The RDA for 0-12 months old babies is 400-600micrograms/day. Most of the vitamin A is stored in the liver, making animal liver an excellent source of vitamin A. Vitamin A deficiency is characterized by the deposits of keratin in the conjunctiva, known as Bitot’s spots, keratomalacia, night blindness, and anaemia.Vitamin A toxicity or excess is characterized by hyperkeratosis, hypothyroidism, hypo/hyperpigmentation, etc.According to WHO guidelines, children under two years of age who develop measles should be given two additional doses of vitamin A supplementation 24 hours apart, which is necessary for preventing eye damage, blindness, and reducing mortality by 50%.

Excessive weight loss is generally indicative of suboptimal feeding, and infants with excessive weight loss are potentially dehydrated or at risk of dehydration.Jaundice associated with suboptimal breastfeeding– this is classically associated with weight loss >10% and a vicious cycle of sleepiness that in turn leads to further poor feeding. In the absence of clinical signs of dehydration, no evidence suggests that overhydration is helpful. If the infant is dehydrated, hydration should be given as clinically indicated. However, if the infant can tolerate oral feeding, oral hydration with a breast milk substitute is likely to be superior to intravenous hydration because it reduces enterohepatic circulation of bilirubin and helps wash bilirubin out of the bowel.

Possible Zika virus infections have been identified in breastfeeding babies, but Zika virus transmission through breast milk has not been confirmed. Additionally, we do not yet know the long-term effects of Zika virus on young infants infected after birth. Because current evidence suggests that the benefits of breastfeeding outweigh the risk of Zika virus spreading through breast milk, CDC continues to encourage mothers to breastfeed, even if they were infected or lived in or travelled to an area with risk of Zika.

Protein energy malnutrition often presents in two common forms, Kwashiorkor and Marasmus. Kwashiorkor is characterised by a protein deficiency with an additional inadequate calorie intake. As a result, affected children present with oedema, muscular atrophy, and their weight for age is 60-80% of the expected weight. Their cutaneous tissue is however preserved. Marasmus on the other hand is characterised by a severe calorie deficiency leading to atrophy of the muscles and adipose tissue, with weight loss being less than 60% of the normal. In both cases, if the child is not promptly rehabilitated, the malnutrition could cause irreversible damage, such as hepatic, cardiac and renal impairments.
