Possible complications include:- Hearing loss (which may be partial or total)- problems with memory and concentration- problems with coordination and balance- learning difficulties (which may be temporary or permanent)- epilepsy (Seizures)- cerebral palsy- speech problems- vision loss (which may be partial or total)As hearing loss is the most common complication of meningitis people recovering from the condition are usually given a hearing test to assess their hearing.

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.

This patient has Wilson’s disease. They Kayser-Fleischer ring (ring that encircles the iris) is diagnostic of this. Low serum copper is seen in Wilson’s disease. With the Kayser-Fleischer ring, this makes all of the other answer choices incorrect.

Classic Kallmann syndrome (KS) is due to isolated hypogonadotropic hypogonadism. Most patients have gonadotropin-releasing hormone (GnRH) deficiency, as suggested by their response to pulsatile GnRH therapy. The hypothalamic-pituitary function is otherwise normal in most patients, and hypothalamic-pituitary imaging reveals no space-occupying lesions. By definition, either anosmia or severe hyposmia is present in patients with Kallmann syndrome.

Recurrent bacterial infections may be due to lack of B-cell function, consequently resulting in a lack of gamma globulins production. Once the maternal antibodies have depleted, the disease manifests with greater severity and is called x-linked agammaglobulinemia also known as ‘X-linked hypogammaglobulinemia’, ‘XLA’ or ‘Bruton-type agammaglobulinemia. it is a rare x linked genetic disorder that compromises the bodies ability to fight infections.
Acute leukaemia causes immunodeficiency but not so specific.
DiGeorge syndrome is due to lack of T cell function.
Aplastic anaemia and EBV infection does not cause immunodeficiency.

Membranoproliferative glomerulonephritis primarily affects children and young adults, with patients presenting with nephrotic or nephritic syndrome or with asymptomatic renal disease. There are 3 types defined by pathologic features. All three types are associated with hypocomplementemia, but they manifest somewhat different mechanisms of complement activation. This type of glomerulonephritis often progresses slowly to end-stage renal disease, and it tends to recur after renal transplantation, especially type II.

People who are at risk for severe illness and complications from measles, such as infants younger than 12 months of age, pregnant women without evidence of measles immunity, and people with severely compromised immune systems, should receive immunoglobulin. Intramuscular immunoglobulin should be given to all infants younger than 12 months of age who have been exposed to measles. For infants aged 6 through 11 months, MMR vaccine can be given in place of IG, if administered within 72 hours of exposure.

A complete course of DPT should be given.

By the age of three months a child should become more fascinated with their hands and fingers| they can bring their hand to their mouth, open and close their hand, and shake and grab at dangling objects and toys. Their ability to roll over will come by the time the child is 6 months, at which time they will also be able to sit with support. Soon, at 8-9 months, attempts will be made to crawl and as they approach 12 months they will be able to pull on objects to stand.

Gitelman syndrome is a kidney disorder that causes an imbalance of charged atoms (ions) in the body, including ions of potassium, magnesium, and calcium.The signs and symptoms of Gitelman syndrome usually appear in late childhood or adolescence. Common features of this condition include painful muscle spasms (tetany), muscle weakness or cramping, dizziness, and salt craving. Also common is a tingling or prickly sensation in the skin (paraesthesia), most often affecting the face. Some individuals with Gitelman syndrome experience excessive tiredness (fatigue), low blood pressure, and a painful joint condition called chondrocalcinosis. Studies suggest that Gitelman syndrome may also increase the risk of a potentially dangerous abnormal heart rhythm called ventricular arrhythmia.

The x-ray is suggestive of bronchiectasis. The most probable aetiology especially considering recurrent chest infections at such a young age is cystic fibrosis.

The characteristic cells in granulomatous inflammation are giant cells, formed from merging macrophages and epithelioid cells elongated with granular eosinophilic cytoplasm. Granulomatous reactions are seen in patients with tuberculosis. A tuberculous/caseating granuloma is characterised by a zone of central necrosis lined with giant multinucleated giant cells (Langhans cells) and surrounded by epithelioid cells, lymphocytes and fibroblasts. The caseous zone is present due to the damaged and dead giant cells and epithelioid cells.
Mast cells are only few in number and fibroblasts lay down collagen.
Basophils are not present.
The giant cell made up of macrophages are the most abundant cells in this inflammatory process.

Based on the clinical scenario, the most likely underlying pathogen is the Epstein Barr virus (EBV).An Epstein Barr virus (EBV) infection most commonly results in upper respiratory tract symptoms with fever and sore throat. Lymphadenopathy is frequently palpable on examination. Splenomegaly may also occur, and for this reason, patients diagnosed with glandular fever should be advised to avoid contact sports for one month following diagnosis. The presence of petechiae on the soft palate is also associated with EBV infection. The vast majority of patients with active EBV infection will develop a widespread rash if given amoxicillin, therefore, phenoxymethylpenicillin (Penicillin V) is recommended for the treatment of a suspected bacterial throat infection to prevent this complication occurring for individuals who have EBV infection.Other options:- Coronavirus: This is one of the causes of the common cold and is frequently responsible for sore throats| however, in this case, the presenting features are more suggestive of an EBV infection.- Group A Streptococcus: Streptococci are classified into two main groups| alpha-haemolytic and beta-haemolytic. Group A Streptococcus belongs to the beta-haemolytic group. Group A streptococcal infection is a common cause of bacterial tonsillitis. It is possible that the child, in this case, had streptococcal tonsillitis and has had a drug reaction to the amoxicillin. However her age, flu-like symptoms and petechiae on her palate all point to an EBV infection and amoxicillin resulting in a rash.- Parainfluenza: Parainfluenza viruses are one of many causes of the common cold and can cause pharyngitis. They are the leading cause of viral croup.- Rhinovirus: Rhinoviruses are one of many causes of the common cold and are frequently responsible for sore throats| however, in this case, are other factors suggesting EBV infection.

A not immunized patient with a clean wound requires an immediate vaccination against diphtheria, tetanus and polio, according to the Green Book of Immunisation against infectious disease. (The Green Book has the latest information on vaccines and vaccination procedures, for vaccine preventable infectious diseases in the UK.)

The chance of having appendicitis again after appendix mass is around 17% in children. While the traditional teachings by Hamilton Bailey recommend following the conservative Ochsner-Sherren regimen followed by an interval appendicectomy six weeks after the discharge of the patient, there remains a looming controversy whether to perform an interval appendicectomy or not.

Psoriasis is an autoimmune dermatological condition that causes cells of the epidermal layer to rapidly develop, leading to itchy scaly plaques. Phototherapy with UV radiation has emerged as a new treatment for difficult to treat psoriasis. The therapy works by inducing epidermal cell apoptosis by DNA damage through the formation of pyrimidine dimerization, disrupting the cell cycle. This slows the rapid proliferation of cells.

Burkitt lymphoma is associated with the c-myc gene translocation, usually t(8|14). Burkitt lymphoma is a rare high-grade non-Hodgkin lymphoma endemic to west Africa and the mosquito belt. It has a close association with the contraction of Epstein-Barr virus (EBV). Burkitt lymphoma often presents with symmetrical painless lymphadenopathy, systemic B symptoms (fever, sweats, and weight loss), central nervous system involvement, and bone marrow infiltration. Classically in the textbooks, the patient also develops a large jaw tumour.Other aforementioned options are ruled out because:1. t(9|22)—Chronic myeloid leukaemia2. t(15|17)—Acute promyelocytic leukaemia3. t(14|18)—Follicular Lymphoma4. t(11|14)—Mantle Cell Lymphoma

The clinical picture suggests that the baby has Beckwith-Wiedemann Syndrome, which predisposes the individual to cancer. The most common childhood tumour that a person with Beckwith-Wiedemann Syndrome may develop is Wilms’ tumour. Typical features include: macrosomia, asymmetric limb growth, macroglossia, neonatal hypoglycaemia, umbilical hernias or other abdominal wall deformities.

The most probable diagnosis for this patient is Maple syrup urine disease (MSUD).Note:- Healthy new-borns have blood sugars between 3.3 and 5 mmol/L- Neonatal hypoglycaemia is glucose < 2.2 mmol/L if measured in the first 3 days of life.- Neonatal hypoglycaemia is glucose < 2.5 mmol/L after the first 3 days of life.Causes of persistent hypoglycaemia include:- Preterm- IUGR- SGA- Hyperinsulinism due to maternal diabetes- Beckwith-Wiedemann syndrome- Hypoxia at birth- Sepsis- Cardiopulmonary disease- Inborn errors of metabolism- Hepatic enzyme deficiencies- Glycogen storage disease

Answer: Inflammatory bowel diseaseThe inflammatory bowel diseases (IBDs), including ulcerative colitis and Crohn disease, are chronic inflammatory disorders of the gastrointestinal tract most often diagnosed in adolescence and young adulthood, with a rising incidence in paediatric populations. Inflammatory bowel disease is caused by a dysregulated mucosal immune response to the intestinal microflora in genetically predisposed hosts. Although children can present with the classic symptoms of weight loss, abdominal pain, and bloody diarrhoea, many present with nonclassical symptoms of isolated poor growth, anaemia, or other extraintestinal manifestations.Colorectal Carcinoma (CRC) is rare in patients less than 20 years of age.

DiGeorge syndrome is one of the most common microdeletion syndromes, resulting from 22q11 deletion. 10% of the cases can be inherited in an autosomal dominant fashion, while 90% are sporadic. The syndrome is characterized by a deficiency of both T and B-cell lines along with hearing loss, 20-fold increased lifetime chances of developing schizophrenia, renal abnormalities, congenital heart defects, and a borderline or low IQ. Distinctive facial features include micrognathia, long face, short philtrum, cleft palate, and small teeth.

Jacob is likely to be four years old as demonstrated by his activities throughout the day. Most 4 year olds are able to run well, jump and hop, but find skipping a little more difficult. They are able to brush their teeth and dress themselves with supervision, and go to the toilet alone.

Fine motor development involves greater use of the hands to perform more precise tasks. By 6 -12 months children should be able to reach for small objects and pass an object from one hand to the other. From 1 -2 years they can perform more complex tasks such a building a tower of blocks, feeding themselves, and turning knobs. In terms of pencil skills, they should be able to imitate scribbles and then spontaneously scribble. By the age of 2 years they can draw a line, and by three they can draw a circle. From the age of 3.5 they can draw a cross, 4.5 – a square, 5 – a triangle, and 6 a diamond.

The correct answer is triple X syndrome with a genotype of XXX and an almost normal female phenotype. The extra X chromosome is inactive. The final phenotype of an individual is determined after normal sexual and gonadal differentiation, a process that involves several genes located on chromosomes X and Y. Disorders of sexual differentiation result in cases of ambiguous genitalia and are caused by a number of genetic abnormalities. Among these disorders is the turner syndrome with a genotype of 45X0, characterized by gonadal dysgenesis and ovarian failure. DAX-1 gene mutation leads to congenital adrenal hypoplasia and hypogonadotropic hypogonadism, which results in virilization of female external genitalia. Campomelic dysplasia results from mutation of the SOX-9 gene, leading to 46XY sex reversal. Danys-Drash syndrome is characterized by disordered sexual development in affected males due to the mutated WT-1 gene, which also causes Wilm’s tumour.

Synchronized IMV (SIMV) with pressure support, used in the alert infant. SIMV guarantees a minimum minute volume while allowing the patient to trigger spontaneousbreaths at a rate and volume determined by the patient. Extra breaths are boosted with pressure support. Tidal Volume (Vt) is normally approximately 6-10 mL/kg and 4-6 ml/kg in the preterm.Respiratory rate (RR) is usually 30-60 BPM. Tidal volume and respiratory rate are relatedto respiratory minute volume as follows: Vm(mL/min) = Vt x RR .This baby is overventilated with a low CO2. Tidal volumes should generally be targeted at 4–6 ml/kg and this baby is being targeted at 9 ml/kg which exposes the baby to damage to the distal airways from this ventilation which can lead to bronchopulmonary dysplasia.

Von Hippel-Lindau syndrome is a genetic disorder inherited in autosomal dominant fashion. It is caused by the mutations of the VHL gene located on chromosome 3. The syndrome is characterized by the creation of multiple benign and malignant tumours involving various bodily systems along with the formation of numerous visceral cysts, including the renal and epididymal cysts. Down’s syndrome is associated with renal cysts, but it does not follow the autosomal dominant mode of inheritance, rather it is caused by non-disjunction of chromosome 21 during meiosis. Exomphalos is a defect of the medial abdominal wall leading to abnormal protrusion of abdominal viscera through it. It is not associated with renal cysts. Turner’s syndrome may be associated with renal cysts formation, but it is not transmitted in an autosomal dominant fashion. Polycystic kidney disease of childhood follows an autosomal recessive pattern of transmission.

Ipecac, or syrup of ipecac (SOI), is a medication once used to induce vomiting. Its medical use has virtually vanished, and it is no longer recommended for routine use in toxic ingestion. The abuse of SOI as a purgative in eating disorders, however, is increasing. Ipecac has a high safety profile. Common side effects include prolonged vomiting (greater than 1 hour), lethargy, somnolence, diarrhoea, fever, irritability. More severe complications can consist of aspiration pneumonia, Mallory-Weiss tears, pneumomediastinum, and gastric rupture.The abuse of syrup of ipecac by patients with major eating disorders have been shown to have toxic effects on the skeletal and cardiac muscle.

Answer: RicketsRickets is a disease of growing bone that is unique to children and adolescents. It is caused by a failure of osteoid to calcify in a growing person. The signs and symptoms of rickets can include:pain – the bones affected by rickets can be sore and painful, so the child may be reluctant to walk or may tire easily| the child’s walk may look different (waddling)skeletal deformities – thickening of the ankles, wrists and knees, bowed legs, soft skull bones and, rarely, bending of the spinedental problems – including weak tooth enamel, delay in teeth coming through and increased risk of cavitiespoor growth and development – if the skeleton doesn’t grow and develop properly, the child will be shorter than averagefragile bones – in severe cases, the bones become weaker and more prone to fractures.Marfan syndrome (MFS) is a genetic disorder of the connective tissue. The degree to which people are affected varies. People with Marfan tend to be tall and thin, with long arms, legs, fingers and toes. They also typically have flexible joints and scoliosis. The most serious complications involve the heart and aorta, with an increased risk of mitral valve prolapse and aortic aneurysm. Other commonly affected areas include the lungs, eyes, bones and the covering of the spinal cord.Ehlers-Danlos syndrome is a group of inherited disorders that affect your connective tissues — primarily your skin, joints and blood vessel walls. People who have Ehlers-Danlos syndrome usually have overly flexible joints and stretchy, fragile skin. This can become a problem if you have a wound that requires stitches, because the skin often isn’t strong enough to hold them.A more severe form of the disorder, called Ehlers-Danlos syndrome, vascular type, can cause the walls of your blood vessels, intestines or uterus to rupture. Osteoporosis is a disease in which bone weakening increases the risk of a broken bone. It is the most common reason for a broken bone among the elderly. Bones that commonly break include the vertebrae in the spine, the bones of the forearm, and the hip. Until a broken bone occurs there are typically no symptoms. Bones may weaken to such a degree that a break may occur with minor stress or spontaneously. Chronic pain and a decreased ability to carry out normal activities may occur following a broken bone.Osteoporosis may be due to lower-than-normal maximum bone mass and greater-than-normal bone loss. Bone loss increases after menopause due to lower levels of oestrogen. Osteoporosis may also occur due to a number of diseases or treatments, including alcoholism, anorexia, hyperthyroidism, kidney disease, and surgical removal of the ovaries.

The IM dose of adrenaline for anaphylaxis in:< 6 months: 150 micrograms (0.15ml 1 in 1,000)6 months - 6 years: 150 micrograms (0.15ml 1 in 1,000)6 - 12 years: 300 micrograms (0.3ml 1 in 1,000)Adult and child > 12 years: 500 micrograms (0.5ml 1 in 1,000)Anaphylaxis:Anaphylaxis is an acute, rapidly progressing, potentially life-threatening IgE mediated Type I hypersensitivity reaction.It involves the release of mediators from mast cells, basophils and inflammatory cells. It is characterised by oedematous swelling of the airway mucosa giving rise to dyspnoea and respiratory distress. The most common cause of anaphylaxis in children is a food allergy.Risk factors for death in patients with anaphylaxis include asthma, age 11+, peanut allergy, and delay in adrenaline administration.Management of anaphylaxis includes:- ABCD- Remove the allergen- IM adrenaline or Nebulised adrenaline- IV Hydrocortisone – pro re nata IV fluid support. – Followed by observation.

Based on the studies, genetic factors are responsible for approximately 60 % DVT cases. Factor V (FV) Leiden which is the most common cause of inherited thrombophilia, predisposes patients to DVT because of resistance to protein C.The heritable causes of deep vein thrombosis, from most to least common are:Factor V LeidenProthrombin G20210A variantProtein C deficiencyProtein S deficiencyAntithrombin deficiencyVon Willebrand disease and thalassaemia are not causes of DVT.
