Managing Acute Asthma Exacerbations in Children: Treatment Options and Guidelines

When a child experiences an acute asthma exacerbation, prompt and appropriate management is crucial to prevent further complications. Here are some treatment options and guidelines to consider:

Inpatient Management with Nebuliser Salbutamol and Oral Steroids
For severe asthma exacerbations, hospital transfer is necessary. Inpatient management should include nebulised bronchodilators in combination with early oral steroids. A 3-day steroid course is usually sufficient.

Manage as Outpatient with Inhaled Salbutamol via Spacer
Mild to moderate acute asthma can be managed with salbutamol via a spacer. Oral steroids should be considered in all children with an acute exacerbation of asthma. However, all children with features of severe or life-threatening asthma should be transferred to a hospital.

Outpatient Management with Antibiotics
Antibiotics would be inappropriate for acute asthma exacerbations unless there are clues in the history to suggest a bacterial infection as the cause of exacerbation.

Continue Current Medications with No Changes
In severe acute asthma, urgent treatment with nebulisers and transfer to a hospital is necessary.

IV Salbutamol
IV salbutamol is second line and considered only if the symptoms have responded poorly to nebulised therapy.

British Thoracic Society (BTS)/Scottish Intercollegiate Guidelines Network (SIGN) guidance suggests that all children with features of severe or life-threatening asthma should be transferred to a hospital. The severity of acute asthma in children over 5 can be determined using the BTS severity scoring.

By following these guidelines and treatment options, healthcare professionals can effectively manage acute asthma exacerbations in children and prevent further complications.

Understanding Urinary Tract Infections in Children

Urinary tract infections (UTIs) are common in children and can present with a variety of symptoms. In older children, diarrhoea with or without mucus may be a presenting symptom, especially with E. coli infection. While amoxicillin is a commonly used antibiotic, current guidelines recommend trimethoprim or nitrofurantoin for lower UTIs and co-amoxiclav for upper UTIs.

Anatomical abnormalities of the urinary tract increase a child’s susceptibility to UTIs, but they are not present in the majority of cases. Imaging studies are not necessary for infants and children with a first episode of cystitis or a first febrile UTI who respond well to treatment and have a normal voiding pattern. Ultrasonography is the preferred imaging study for children with UTIs.

Escherichia coli is the most common organism isolated in paediatric UTIs, but other organisms such as fungi and viruses can also cause infection. Poor containment of infection is more common in infants younger than 2 months, and UTIs can spread to the kidneys and bloodstream if left untreated.

Understanding the symptoms and treatment options for UTIs in children is important for prompt diagnosis and management.

According to the 2011 NICE guidelines, the treatment for isolated systolic hypertension should be the same as that for standard hypertension, with calcium channel blockers being the preferred first-line medication for this age group.

Understanding Isolated Systolic Hypertension

Isolated systolic hypertension (ISH) is a common condition among the elderly, affecting approximately 50% of individuals over the age of 70. The Systolic Hypertension in the Elderly Program (SHEP) conducted in 1991 found that treating ISH can reduce the risk of strokes and ischaemic heart disease. The first line of treatment for ISH was thiazides. However, the 2011 NICE guidelines recommend treating ISH in the same stepwise manner as standard hypertension, which contradicts the previous approach.

It is important to understand ISH as it is a prevalent condition among the elderly population. The SHEP study showed that treating ISH can significantly reduce the risk of serious health complications. However, the recommended approach to treating ISH has changed over time, with the 2011 NICE guidelines suggesting a different method than the previous recommendation of using thiazides as the first line of treatment. It is crucial for healthcare professionals to stay up-to-date with the latest guidelines to provide the best possible care for patients with ISH.

Torsades de pointes can be treated with IV magnesium sulfate.

Torsades de Pointes: A Life-Threatening Condition

Torsades de pointes is a type of ventricular tachycardia that is associated with a prolonged QT interval. This condition can lead to ventricular fibrillation, which can cause sudden death. There are several causes of a prolonged QT interval, including congenital conditions such as Jervell-Lange-Nielsen syndrome and Romano-Ward syndrome, as well as certain medications like antiarrhythmics, tricyclic antidepressants, and antipsychotics. Other causes include electrolyte imbalances, myocarditis, hypothermia, and subarachnoid hemorrhage.

The management of torsades de pointes involves the administration of intravenous magnesium sulfate. This can help to stabilize the heart rhythm and prevent further complications.

When a woman presents with a breast lump, fat necrosis should be considered as a possible diagnosis if there is a history of trauma to the area. This condition typically presents as a firm lump that may be accompanied by bruising. Fibroadenomas, on the other hand, are more commonly seen in younger women and present as a mobile but firm lump that can be easily moved during examination. Breast cysts are fluid-filled masses that may be detected if they are large enough and can fluctuate or transilluminate. Breast abscesses are typically seen in breastfeeding women and present as a hot, tender swelling. While breast cancer is unlikely based on the clinical history, all women with a breast lump should be referred to a specialist for confirmation of diagnosis through triple assessment. It is important to note that intentional weight loss, as in this case, should not be considered a factor in the diagnosis.

Understanding Fat Necrosis of the Breast

Fat necrosis of the breast is a condition that affects up to 40% of cases and is often caused by trauma. This condition can be mistaken for breast cancer due to its physical features, such as a mass that may initially increase in size. It is important to understand that fat necrosis is not cancerous and can be treated with proper care.

Gonorrhoea is best treated with intramuscular ceftriaxone, and it is crucial to notify and treat sexual partners. All patients with gonorrhoea should undergo a test of cure after 2 weeks.

Understanding Gonorrhoea: Causes, Symptoms, Microbiology, and Management

Gonorrhoea is a sexually transmitted infection caused by the Gram-negative diplococcus Neisseria gonorrhoeae. It can occur on any mucous membrane surface, including the genitourinary tract, rectum, and pharynx. The incubation period of gonorrhoea is typically 2-5 days. Symptoms in males include urethral discharge and dysuria, while females may experience cervicitis leading to vaginal discharge. Rectal and pharyngeal infections are usually asymptomatic.

Immunisation against gonorrhoea is not possible, and reinfection is common due to antigen variation of type IV pili and Opa proteins. Local complications may develop, including urethral strictures, epididymitis, and salpingitis, which can lead to infertility. Disseminated infection may also occur, with gonococcal infection being the most common cause of septic arthritis in young adults.

Management of gonorrhoea involves the use of antibiotics. Ciprofloxacin used to be the treatment of choice, but there is now increased resistance to it. Cephalosporins are now more widely used, with a single dose of IM ceftriaxone 1g being the new first-line treatment. If ceftriaxone is refused, oral cefixime 400mg + oral azithromycin 2g should be used. Disseminated gonococcal infection (DGI) and gonococcal arthritis may also occur, with symptoms including tenosynovitis, migratory polyarthritis, and dermatitis. Later complications include septic arthritis, endocarditis, and perihepatitis.

Patients starting bisphosphonates should be warned about potential oesophageal problems, particularly with alendronate. Any new symptoms following the introduction of this drug should be reviewed by a medical professional.

Bisphosphonates: Uses and Adverse Effects

Bisphosphonates are drugs that mimic the action of pyrophosphate, a molecule that helps prevent bone demineralization. They work by inhibiting osteoclasts, which are cells that break down bone tissue. This reduces the risk of bone fractures and can be used to treat conditions such as osteoporosis, hypercalcemia, Paget’s disease, and pain from bone metastases.

However, bisphosphonates can have adverse effects, including oesophageal reactions such as oesophagitis and ulcers, osteonecrosis of the jaw, and an increased risk of atypical stress fractures of the proximal femoral shaft in patients taking alendronate. Patients may also experience an acute phase response, which can cause fever, myalgia, and arthralgia. Hypocalcemia, or low calcium levels, can also occur due to reduced calcium efflux from bone, but this is usually not clinically significant.

To minimize the risk of adverse effects, patients taking oral bisphosphonates should swallow the tablets whole with plenty of water while sitting or standing. They should take the medication on an empty stomach at least 30 minutes before breakfast or other oral medications and remain upright for at least 30 minutes after taking the tablet. Hypocalcemia and vitamin D deficiency should be corrected before starting bisphosphonate treatment, and calcium supplements should only be prescribed if dietary intake is inadequate. The duration of bisphosphonate treatment varies depending on the patient’s level of risk, and some authorities recommend stopping treatment after five years for low-risk patients with a femoral neck T-score of > -2.5.

If the police believe that someone requires a mental health assessment or treatment, they can request a section 135 to remove the individual from their property. The procedure involves an Approved Mental Health Practitioner (AMHP) presenting evidence at a Magistrate’s Court to obtain a warrant. This warrant permits the Police, an AMHP, and a registered medical practitioner to enter the premises and conduct an assessment or take the person to a safe location for evaluation.

Sectioning under the Mental Health Act is a legal process used for individuals who refuse voluntary admission. This process excludes patients who are under the influence of drugs or alcohol. There are several sections under the Mental Health Act that allow for different types of admission and treatment.

Section 2 allows for admission for assessment for up to 28 days, which is not renewable. An Approved Mental Health Professional (AMHP) or the nearest relative (NR) can make the application on the recommendation of two doctors, one of whom should be an approved consultant psychiatrist. Treatment can be given against the patient’s wishes.

Section 3 allows for admission for treatment for up to 6 months, which can be renewed. An AMHP and two doctors, both of whom must have seen the patient within the past 24 hours, can make the application. Treatment can also be given against the patient’s wishes.

Section 4 is used as an emergency 72-hour assessment order when a section 2 would involve an unacceptable delay. A GP and an AMHP or NR can make the application, which is often changed to a section 2 upon arrival at the hospital.

Section 5(2) allows a doctor to legally detain a voluntary patient in hospital for 72 hours, while section 5(4) allows a nurse to detain a voluntary patient for 6 hours.

Section 17a allows for Supervised Community Treatment (Community Treatment Order) and can be used to recall a patient to the hospital for treatment if they do not comply with the conditions of the order in the community, such as taking medication.

Section 135 allows for a court order to be obtained to allow the police to break into a property to remove a person to a Place of Safety. Section 136 allows for someone found in a public place who appears to have a mental disorder to be taken by the police to a Place of Safety. This section can only be used for up to 24 hours while a Mental Health Act assessment is arranged.

Understanding Cocaine Toxicity

Cocaine is a popular recreational stimulant derived from the coca plant. However, its widespread use has resulted in an increase in cocaine toxicity cases. The drug works by blocking the uptake of dopamine, noradrenaline, and serotonin, leading to a variety of adverse effects.

Cardiovascular effects of cocaine include coronary artery spasm, tachycardia, bradycardia, hypertension, QRS widening, QT prolongation, and aortic dissection. Neurological effects may include seizures, mydriasis, hypertonia, and hyperreflexia. Psychiatric effects such as agitation, psychosis, and hallucinations may also occur. Other complications include ischaemic colitis, hyperthermia, metabolic acidosis, and rhabdomyolysis.

Managing cocaine toxicity involves using benzodiazepines as a first-line treatment for most cocaine-related problems. For chest pain, benzodiazepines and glyceryl trinitrate may be used, and primary percutaneous coronary intervention may be necessary if myocardial infarction develops. Hypertension can be treated with benzodiazepines and sodium nitroprusside. The use of beta-blockers in cocaine-induced cardiovascular problems is controversial, with some experts warning against it due to the risk of unopposed alpha-mediated coronary vasospasm.

In summary, cocaine toxicity can lead to a range of adverse effects, and managing it requires careful consideration of the patient’s symptoms and medical history.

Do not perform oral or throat examination on a child with suspected acute epiglottitis as it may lead to further airway obstruction and distress. Basic observations can be done but call the senior paediatric team and an anaesthetist.

Stridor in Children: Causes and Symptoms

Stridor is a high-pitched, wheezing sound that occurs during breathing and is commonly seen in children. There are several causes of stridor in children, including croup, acute epiglottitis, inhaled foreign body, and laryngomalacia. Croup is a viral infection that affects the upper respiratory tract and is characterized by stridor, barking cough, fever, and coryzal symptoms. Acute epiglottitis is a rare but serious infection caused by Haemophilus influenzae type B, which can lead to airway obstruction. Inhaled foreign body can cause sudden onset of coughing, choking, vomiting, and stridor, depending on the site of impaction. Laryngomalacia is a congenital abnormality of the larynx that typically presents at 4 weeks of age with stridor.

It is important to recognize the symptoms of stridor in children and seek prompt medical attention, especially if the child appears unwell or toxic. Treatment may include medications, such as corticosteroids or nebulized epinephrine, or in severe cases, intubation or tracheostomy. Prevention measures, such as vaccination against Haemophilus influenzae type B, can also help reduce the incidence of acute epiglottitis. Overall, early recognition and management of stridor in children can help prevent complications and improve outcomes.
