Understanding ADHD: Symptoms and Diagnostic Criteria

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects both children and adults. One of the diagnostic criteria for ADHD is impulsivity, which can manifest as difficulty waiting turns, interrupting others, or blurting out answers prematurely. However, restricted, repetitive behaviors are not a symptom of ADHD but rather a diagnostic criterion for autism spectrum disorder. Similarly, aggression towards people and animals is not a symptom of ADHD but is included in the diagnostic criteria for conduct disorder. Argumentative or defiant behavior is also not a symptom of ADHD but is a diagnostic criterion for oppositional defiant disorder. It is important to note that high educational attainment is not a diagnostic criterion for ADHD, as individuals with ADHD may struggle in school due to inattention and difficulty concentrating. Understanding the symptoms and diagnostic criteria for ADHD can aid in early identification and appropriate treatment.

Many referrals for orthopaedic outpatient care from general practitioners are actually normal variants. The defining characteristics of normal variants are that they are always symmetrical, painless, and improve with age.

Genu varum, or bow legs, is a normal variant from birth until about 2 years of age. Referral should be considered if genu varum is asymmetrical or persists beyond 3 years of age. Severe cases may be indicative of vitamin D deficiency. Genu valgus, or knock knees, is a normal variant between 3-6 years of age. Again, referral should be considered if the valgus is severe or persists, and vitamin D deficiency may be a factor. Flat feet are a normal variant until age 3, and most cases resolve by age 8 as the foot arch develops. Arches should appear when the infant stands on their tip toes, and the foot should be flexible and painless. Painful rigid flat feet should always be referred and may suggest tarsal coalition.

In-toeing has three main causes: metatarsus adductus (a congenital foot deformity), internal tibial torsion (feet internally rotated), and femoral anteversion (feet and knees internally rotated). The vast majority of cases resolve by around 8 years of age.

Paediatric Orthopaedics: Common Conditions and Treatments

Developmental dysplasia of the hip is a condition that is usually diagnosed in infancy through screening tests. It may be bilateral, and when it is unilateral, there may be leg length inequality. As the disease progresses, the child may limp and experience early onset arthritis. This condition is more common in extended breech babies. Treatment options include splints and harnesses or traction, and in later years, osteotomy and hip realignment procedures may be needed. In cases of arthritis, a joint replacement may be necessary, but it is best to defer this if possible as it will likely require revision. Initially, there may be no obvious changes on plain films, and ultrasound gives the best resolution until three months of age. On plain films, Shenton’s line should form a smooth arc.

Perthes Disease is characterized by hip pain, which may be referred to the knee, and usually occurs between the ages of 5 and 12. Bilateral disease occurs in 20% of cases. Treatment involves removing pressure from the joint to allow for normal development and physiotherapy. If diagnosed and treated promptly, the condition is usually self-limiting. X-rays will show a flattened femoral head, and in untreated cases, the femoral head will eventually fragment.

Slipped upper femoral epiphysis is typically seen in obese male adolescents. Pain is often referred to the knee, and limitation to internal rotation is usually seen. Knee pain is usually present two months prior to hip slipping, and bilateral disease occurs in 20% of cases. Treatment involves bed rest and non-weight bearing to avoid avascular necrosis. If severe slippage or risk of it occurring is present, percutaneous pinning of the hip may be required. X-rays will show the femoral head displaced and falling inferolaterally, resembling a melting ice cream cone. The Southwick angle gives an indication of disease severity.

Understanding Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a condition that is often accompanied by a learning disability. Children with ASD typically experience difficulties with social communication, interaction, and imagination. These challenges can manifest in a variety of ways, such as difficulty making eye contact, trouble understanding social cues, and a lack of interest in imaginative play.

Despite the challenges that come with ASD, there have been significant advances in diagnosis and evaluation in recent years. With early intervention and support, children with ASD can learn to navigate the world around them and lead fulfilling lives. It is important for parents, caregivers, and educators to understand the unique needs of children with ASD and provide them with the resources and support they need to thrive.

Developmental dysplasia of the hip (DDH) is a condition that affects 1-3% of newborns and is more common in females, firstborn children, and those with a positive family history or breech presentation. It used to be called congenital dislocation of the hip (CDH). DDH is more often found in the left hip and can be screened for using ultrasound in infants with certain risk factors or through clinical examination using the Barlow and Ortolani tests. Other factors to consider include leg length symmetry, knee level when hips and knees are flexed, and restricted hip abduction in flexion. Ultrasound is typically used to confirm the diagnosis, but x-rays may be necessary for infants over 4.5 months old. Management options include the Pavlik harness for younger children and surgery for older ones. Most unstable hips will stabilize on their own within 3-6 weeks.

Management of Constipation in a 12-Month-Old Child

This 12-month-old child has presented with constipation. Referral for specialist assessment or further investigation is not necessary at this stage, as there are no red flags in the history or examination. Treatment should be initiated in primary care.

A rectal examination is not necessary for the primary care assessment. A thorough history and examination, as discussed in the stem, is sufficient to make an accurate diagnosis and identify the presence of any impaction.

The first-line treatment for constipation is laxative treatment. A good first-line agent is macrogol polyethylene glycol 3350 with electrolytes (Movicol® Paediatric Plain). If there is a lack of effect, a stimulant laxative such as senna can be added to the treatment. In addition to laxative use, the patient and carers should be advised on lifestyle factors such as diet, including adequate fluid intake.

Behavioural interventions, such as scheduled toileting, encouragement, and reward systems, may be appropriate depending on the age of the patient. Advice on exercise in older children may also be helpful. However, dietary interventions should not be used alone as a first-line treatment. Early use of a laxative is indicated and is the most appropriate option.

The fully formed pincer grip is the latest fine motor development that can be expected at 12 months old. While finger pointing typically develops around 9 months old, there is no indication that the child in question has achieved this milestone yet. The palmar grasp, which is typically present at 6 months old, was only achieved at 9 months old, suggesting a potential developmental delay. Passing an object from one hand to another should be present at 6 months old but was only achieved at 12 months old. Reaching for an object is expected at 3 months old in normal development.

Fine Motor and Vision Developmental Milestones

Fine motor and vision developmental milestones are important indicators of a child’s growth and development. At three months, a baby can reach for objects and hold a rattle briefly if given to their hand. They are visually alert, particularly to human faces, and can fix and follow to 180 degrees. By six months, they can hold objects in a palmar grasp and pass them from one hand to another. They become visually insatiable, looking around in every direction. At nine months, they can point with their finger and develop an early pincer grip. By 12 months, they have a good pincer grip and can bang toys together.

In terms of bricks, a 15-month-old can build a tower of two, while an 18-month-old can build a tower of three. A two-year-old can build a tower of six, and a three-year-old can build a tower of nine. When it comes to drawing, an 18-month-old can make circular scribbles, while a two-year-old can copy a vertical line. A three-year-old can copy a circle, a four-year-old can copy a cross, and a five-year-old can copy a square and triangle.

It’s important to note that hand preference before 12 months is abnormal and may indicate cerebral palsy. These milestones serve as a guide for parents and caregivers to monitor a child’s development and ensure they are meeting their milestones appropriately.

Macroorchidism is a common feature of Fragile X syndrome, which also presents with delayed developmental milestones and learning difficulties (typically with an IQ less than 70). Physical characteristics include a high forehead, facial asymmetry, a large jaw, and long ears. Diagnosis is often made by age 3 due to developmental delays. Life-threatening cardiovascular issues and full lips are not associated with FXS, but are seen in William’s syndrome. Down’s syndrome is characterized by decreased muscle tone and hypothyroidism.

Fragile X Syndrome: A Genetic Disorder

Fragile X syndrome is a genetic disorder caused by a trinucleotide repeat. It affects males more severely than females, with symptoms including learning difficulties, large low set ears, a long thin face, high arched palate, macroorchidism, hypotonia, and a higher likelihood of autism. Mitral valve prolapse is also common in males with this syndrome. Females who have one fragile chromosome and one normal X chromosome may have a range of symptoms from normal to mild.

Diagnosis of fragile X syndrome can be made antenatally through chorionic villus sampling or amniocentesis. Analysis of the number of CGG repeats using restriction endonuclease digestion and Southern blot analysis is also used to diagnose this disorder. Proper diagnosis and management can help individuals with fragile X syndrome lead fulfilling lives.

According to the NICE traffic light system, reduced skin turgor is a red flag symptom in a child. This patient is displaying several symptoms of dehydration, including diarrhoea and vomiting for four days. He has three amber symptoms, including pallor reported by parent/carer, decreased urine output, and dry mucous membranes. Additionally, he has two red symptoms, including appearing ill to a healthcare professional and reduced skin turgor. Although his heart rate and respiratory rate are within normal ranges for his age, he requires admission to the hospital for rehydration and care under the paediatric team.

The NICE Feverish illness in children guidelines were introduced in 2007 and updated in 2013 to provide a ‘traffic light’ system for assessing the risk of febrile illness in children under 5 years old. The guidelines recommend recording the child’s temperature, heart rate, respiratory rate, and capillary refill time, as well as looking for signs of dehydration. Measuring temperature should be done with an electronic thermometer in the axilla for children under 4 weeks or with an electronic/chemical dot thermometer in the axilla or an infra-red tympanic thermometer. The risk stratification table categorizes children as green (low risk), amber (intermediate risk), or red (high risk) based on their symptoms. Management recommendations vary depending on the risk level, with green children managed at home, amber children provided with a safety net or referred to a specialist, and red children urgently referred to a specialist. The guidelines also advise against prescribing oral antibiotics without an apparent source of fever and note that a chest x-ray is not necessary if a child with suspected pneumonia is not being referred to the hospital.

Roseola infantum, also known as ‘sixth disease’, is a common illness among children aged 6 months to 2 years. It is characterized by a fever followed by a non-itchy, painless, maculopapular rash that typically affects the trunk. Febrile seizures are also common. The rash usually lasts for about 2 days and doesn’t blister. Roseola is caused by the human herpesvirus type 6B or 7, and no treatment is required. Long-term complications are rare.

Chickenpox, on the other hand, would cause a very itchy rash with blistering lesions that eventually scab over. Hand, foot and mouth disease would typically affect the limbs and mouth, rather than the trunk. Measles would start from the face and spread down to the limbs, and the fever would not subside with the appearance of the rash. Rubella would cause a rash that starts from the face and disappears after 3 days. These characteristics make these illnesses less likely diagnoses in this case.

Understanding Roseola Infantum

Roseola infantum, also known as exanthem subitum or sixth disease, is a common illness that affects infants and is caused by the human herpesvirus 6 (HHV6). The incubation period for this disease is between 5 to 15 days, and it typically affects children between the ages of 6 months to 2 years.

The symptoms of roseola infantum include a high fever that lasts for a few days, followed by a maculopapular rash. Other symptoms that may be present include Nagayama spots, which are papular enanthems on the uvula and soft palate, as well as cough and diarrhea. In some cases, febrile convulsions may occur in around 10-15% of cases.

While roseola infantum can lead to other complications such as aseptic meningitis and hepatitis, school exclusion is not necessary.

Correcting Misconceptions About Child Health: Understanding When to Seek Medical Advice

As a parent or caregiver, it can be difficult to know when to seek medical advice for a child’s health concerns. However, it is important to correct some common misconceptions to ensure that children receive appropriate care.

Firstly, if a parent or caregiver feels that a child has become less well, they should seek further advice. Additionally, if they are distressed or concerned about their ability to care for the child, seeking advice is recommended.

Contrary to popular belief, a strong normal cry is not a cause for concern. However, a weak, high-pitched, or continuous cry is a red flag. Similarly, a non-blanching rash should cause concern, as it may indicate meningococcal septicaemia.

Parents should seek further advice if a fever is still present after five days, not two. A temperature rise up to 39°C in the absence of other worrying signs is not a reason for concern in a child of this age. However, if a child has a febrile fit, parents should seek immediate advice.

By understanding these misconceptions and knowing when to seek medical advice, parents and caregivers can ensure that children receive appropriate care for their health concerns.
