At least seven episodes in the previous year, five episodes in each of the previous two years, or three episodes in each of the previous three years are indications for tonsillectomy. Antibiotics should be administered in the conventional dosage for proved or suspected streptococcal episodes. For now the child should be treated on a case by case basis.

Maternal and fetal toxoplasma infection may be avoided by advising pregnant women to wear gloves when gardening or handling cat litter and to cook meat thoroughly. Affected babies are treated with pyrimethamine, sulfadiazine, and folic acid.

The embryonic period comprises of the first 8 weeks of pregnancy. It is divided into a preembryonic phase (from the 1st to the 3rd week), in which the three germinal layers arise, and into the embryonic phase proper (from the 4th to 8th week), in which the embryonic organ anlagen arise.

Munchausen syndrome by proxy is a mental illness and a form of child abuse. The caretaker of a child, most often a mother or a father, either makes up fake symptoms or causes real symptoms to make it look like the child is sick. The person with MSP gains attention by seeking medical help for exaggerated or made-up symptoms of a child in his or her care. As health care providers strive to identify what’s causing the child’s symptoms, the deliberate actions of the mother or caretaker can often make the symptoms worse.The person with MSP does not seem to be motivated by a desire for any type of material gain. People with MSP may create or exaggerate a child’s symptoms in several ways. They may simply lie about symptoms, alter tests (such as contaminating a urine sample), falsify medical records, or they may actually induce symptoms through various means, such as poisoning, suffocating, starving, and causing infection.

ADH primarily acts on the collecting ducts.Other options:- The juxtaglomerular apparatus is the site of renin production.- The proximal tubule conducts isosmotic reabsorption of about 60% of sodium chloride and volume. Most of the glucose, amino acids, potassium and phosphate are absorbed here.- The loop of Henle is the site of 25% of sodium reabsorption. Active Chloride transport provides the basis for the counter current multiplier aiding urinary concentration.- The distal convoluted tubule is impermeable to water and acts via active sodium chloride absorption to dilute urine.

Benign intracranial hypertension is characterized by an elevation of the CSF pressure that is not caused by hydrocephalus or any space-occupying lesion. The cause is most likely the decreased absorption of CSF into the dural sinuses. The main symptoms are headache and visual abnormalities. It can lead to blindness if not managed on time. The most important risk factors for BIH are female gender and obesity. The causes of BIH include iron deficiency anaemia, sarcoidosis, Lyme disease, SLE, polycythaemia vera, chronic kidney disease, meningitis, and sleep apnoea.

Hirsutism is the growth of excess hair in androgen dependent areas or in a male pattern. The phenomenon is found in conditions where there is abnormal androgen action. This can occur in adrenal lesions including congenital adrenal hyperplasia, and Cushing syndrome, or a failure to produce adequate female hormones such as PCOS and premature menopause. Similarly, drugs such as anabolic steroids, danazol and minoxidil can also cause hirsutism. Delayed puberty is unlikely to cause hirsutism.

Most healthy infants and children grow predictably, following a typical pattern of progression in weight, length, and head circumference. Normal human growth is pulsatile| periods of rapid growth (growth spurts) are separated by periods of no measurable growth Growth hormone levels and responsiveness’ develop in late infancy, increase during childhood and peak during puberty.Typical milestones — General guidelines regarding length or height gain during infancy and childhood include the following:- The average length at birth for a term infant is 20 inches (50 cm)- Infants grow 10 inches (25 cm) during the first year of life- Toddlers grow 4 inches (10 cm) between 12 and 24 months, 3 inches (7.5 cm) between 24 and 36 months, and 3 inches (7.5 cm) between 36 and 48 months- Children reach one-half of their adult height by 24 to 30 months- Children grow 2 inches per year (5 cm per year) between age four years and puberty- There is a normal deceleration of height velocity before the pubertal growth spurt.Growth continues past pubertal growth spurt as there is increase in spinal length.

The patient is suffering from an anaphylactic reaction to the cashew nut he consumed.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:- Resuscitation – ABCD- Remove the allergen- IM adrenaline is given at ten microgram/kg or Nebulised adrenaline 5ml 1:1,000- IV Hydrocortisone is given at 4mg/kg- pro re nata IV fluid support. – Followed by observation.

Injuries to the peroneal nerve can cause numbness, tingling, pain, weakness and foot drop. The branches of the common peroneal nerve innervate and control the muscles in the legs that lift the ankle and toes upward (dorsi flexion).
