Understanding Facial Paralysis: Causes, Symptoms, and Treatment Options

Facial paralysis can be caused by a variety of factors, including lower motor neurone lesions, upper motor neurone lesions, herpes zoster, Lyme disease, and sarcoidosis. In cases of lower motor neurone lesions, patients may be unable to wrinkle their forehead due to the destruction of the final common pathway to the muscles. However, in upper motor neurone lesions, the forehead muscles may be partially spared due to alternative pathways in the brainstem.

Bell’s palsy, also known as idiopathic facial paralysis, is the most common cause of unilateral facial paralysis. While further testing or referral is not usually required, it’s important to assess patients to exclude other possible identifiable causes. Symptoms of Bell’s palsy may include the inability to close the eye, pain, and vesicles in the ear, hard palate, and anterior two thirds of the tongue.

Steroids, such as prednisolone, are an effective treatment for Bell’s palsy and should be started within 72 hours of onset. This treatment option can also be used in children. Full recovery occurs in approximately 80% of cases. If the failure to close the eye is endangering the cornea, further intervention may be necessary.

In conclusion, understanding the causes, symptoms, and treatment options for facial paralysis is crucial for proper diagnosis and management of this condition.

Understanding RIDDOR and Reportable Accidents

For the purposes of RIDDOR, an accident is defined as a separate, identifiable, unintended incident that causes physical injury. This includes acts of non-consensual violence to people at work. However, not all accidents need to be reported. A RIDDOR report is only required when the accident is work-related and results in an injury of a type which is reportable as listed under HSE’s list of ‘Types of reportable injuries’.

In this case, exercise-induced asthma, myopia, and type 1 diabetes are not work-related. Fractures to fingers, thumbs, and toes are excluded from reporting, but other fractures are reportable. Occupational diseases such as occupational asthma or dermatitis are also reportable.

It is important to understand the criteria for reportable accidents under RIDDOR to ensure that incidents are reported appropriately.

If a child between the ages of 6 and 11 is experiencing an anaphylactic reaction, they should be given a dose of 300 micrograms (0.3ml) of adrenaline. This dose can be repeated every 5 minutes if necessary. Based on the patient’s age of 8 years old, it is recommended to administer the adrenaline at a dose of 300 micrograms IM immediately, as stated in the BNF. It is likely that the child is having an anaphylactic reaction to the nuts they were exposed to in the GP waiting room.

Anaphylaxis is a severe and potentially life-threatening allergic reaction that affects the entire body. It can be caused by various triggers, including food, drugs, and insect venom. The symptoms of anaphylaxis typically develop suddenly and progress rapidly, affecting the airway, breathing, and circulation. Swelling of the throat and tongue, hoarse voice, and stridor are common airway problems, while respiratory wheeze and dyspnea are common breathing problems. Hypotension and tachycardia are common circulation problems. Skin and mucosal changes, such as generalized pruritus and widespread erythematous or urticarial rash, are also present in around 80-90% of patients.

The most important drug in the management of anaphylaxis is intramuscular adrenaline, which should be administered as soon as possible. The recommended doses of adrenaline vary depending on the patient’s age, with the highest dose being 500 micrograms for adults and children over 12 years old. Adrenaline can be repeated every 5 minutes if necessary. If the patient’s respiratory and/or cardiovascular problems persist despite two doses of IM adrenaline, IV fluids should be given for shock, and expert help should be sought for consideration of an IV adrenaline infusion.

Following stabilisation, non-sedating oral antihistamines may be given to patients with persisting skin symptoms. Patients with a new diagnosis of anaphylaxis should be referred to a specialist allergy clinic, and an adrenaline injector should be given as an interim measure before the specialist allergy assessment. Patients should be prescribed two adrenaline auto-injectors, and training should be provided on how to use them. A risk-stratified approach to discharge should be taken, as biphasic reactions can occur in up to 20% of patients. The Resus Council UK recommends a fast-track discharge for patients who have had a good response to a single dose of adrenaline and have been given an adrenaline auto-injector and trained how to use it. Patients who require two doses of IM adrenaline or have had a previous biphasic reaction should be observed for a minimum of 6 hours after symptom resolution, while those who have had a severe reaction requiring more than two doses of IM adrenaline or have severe asthma should be observed for a minimum of 12 hours after symptom resolution. Patients who present late at night or in areas where access to emergency care may be difficult should also be observed for a minimum of 12

St John’s Wort and Medication Interactions

St John’s wort is a popular natural remedy for depressive symptoms. However, it is important to note that it is a liver enzyme inducer, which can lead to interactions with other medications. For example, St John’s wort may reduce the efficacy of warfarin, a blood thinner, requiring an increased dose to maintain the desired level of anticoagulation. It may also reduce the efficacy of digoxin, a medication used to treat heart failure. Therefore, it is important to discuss the use of St John’s wort with a healthcare provider before taking it in combination with other medications. By doing so, potential interactions can be identified and managed appropriately.

A certain percentage of individuals diagnosed with SLE exhibit positivity for rheumatoid factor.

Systemic lupus erythematosus (SLE) can be investigated through various tests, including antibody tests. ANA testing is highly sensitive and useful for ruling out SLE, but it has low specificity. About 99% of SLE patients are ANA positive. Rheumatoid factor testing is positive in 20% of SLE patients. Anti-dsDNA testing is highly specific (>99%) but less sensitive (70%). Anti-Smith testing is also highly specific (>99%) but has a lower sensitivity (30%). Other antibody tests that can be used include anti-U1 RNP, SS-A (anti-Ro), and SS-B (anti-La).

Monitoring of SLE can be done through various markers, including inflammatory markers such as ESR. During active disease, CRP levels may be normal, and a raised CRP may indicate an underlying infection. Complement levels (C3, C4) are low during active disease due to the formation of complexes that lead to the consumption of complement. Anti-dsDNA titres can also be used for disease monitoring, but it is important to note that they are not present in all SLE patients. Overall, these investigations can help diagnose and monitor SLE, allowing for appropriate management and treatment.

Identifying Symptoms that Require Active Intervention in Primary Care

It is crucial to differentiate symptoms that require active intervention from those that favor general advice and monitoring in primary care. If there are five or more diagnostic symptoms, occasional suicidal thoughts, no apparent stress trigger, and symptoms present for more than two weeks, this indicates more severe disease. In such cases, active intervention is more likely to be necessary. On the other hand, the four incorrect options favor general advice and monitoring. Therefore, it is essential to identify the symptoms that require active intervention to provide appropriate care to patients.

The typical presentation of vestibular schwannoma involves a combination of symptoms such as vertigo, hearing loss, tinnitus, and an absent corneal reflex. On the other hand, the symptoms of acoustic neuroma may vary depending on the cranial nerve affected. In this case, the patient’s tinnitus and hearing loss suggest that the vestibulocochlear nerve is affected, and vertigo may also be present. Sensorineural hearing loss is observed in acoustic neuroma, whereas otosclerosis, impacted wax, and cholesteatoma cause conductive hearing loss. Meniere’s disease is characterized by progressive hearing loss that fluctuates in severity depending on the attacks.

Vestibular schwannomas, also known as acoustic neuromas, make up about 5% of intracranial tumors and 90% of cerebellopontine angle tumors. These tumors typically present with a combination of vertigo, hearing loss, tinnitus, and an absent corneal reflex. The specific symptoms can be predicted based on which cranial nerves are affected. For example, cranial nerve VIII involvement can cause vertigo, unilateral sensorineural hearing loss, and unilateral tinnitus. Bilateral vestibular schwannomas are associated with neurofibromatosis type 2.

If a vestibular schwannoma is suspected, it is important to refer the patient to an ear, nose, and throat specialist urgently. However, it is worth noting that these tumors are often benign and slow-growing, so observation may be appropriate initially. The diagnosis is typically confirmed with an MRI of the cerebellopontine angle, and audiometry is also important as most patients will have some degree of hearing loss. Treatment options include surgery, radiotherapy, or continued observation.

The earliest and most common symptom of spinal cord compression is back pain.

Neoplastic Spinal Cord Compression: An Oncological Emergency

Neoplastic spinal cord compression is a medical emergency that affects around 5% of cancer patients. The majority of cases are due to vertebral body metastases, which are more common in patients with lung, breast, and prostate cancer. The earliest and most common symptom is back pain, which may worsen when lying down or coughing. Other symptoms include lower limb weakness and sensory changes such as numbness and sensory loss. The neurological signs depend on the level of the lesion, with lesions above L1 resulting in upper motor neuron signs in the legs and a sensory level, while lesions below L1 cause lower motor neuron signs in the legs and perianal numbness. Tendon reflexes tend to be increased below the level of the lesion and absent at the level of the lesion.

Urgent MRI is recommended within 24 hours of presentation according to the 2019 NICE guidelines. High-dose oral dexamethasone is used for management, and urgent oncological assessment is necessary for consideration of radiotherapy or surgery. Proper management is crucial to prevent further damage to the spinal cord and improve the patient’s quality of life.

For adults with mild facial cellulitis, the recommended treatment is a 7-day course of co-amoxiclav or clarithromycin for those with a penicillin allergy. A review should be arranged after 48 hours, either by telephone or face-to-face, depending on clinical judgement.

Urgent hospital admission is necessary for patients with red flags such as Eron Class III or IV cellulitis, severe or rapidly deteriorating cellulitis, immunocompromised individuals, very young or frail patients, those with significant lymphoedema, and those with facial or periorbital cellulitis unless it is very mild. For Eron Class II cellulitis, admission may not be necessary if the community has the facilities and expertise to administer intravenous antibiotics and monitor the patient, subject to local guidelines.

The Eron classification system can assist in determining the appropriate level of care and treatment. Class I patients show no signs of systemic toxicity and have no uncontrolled co-morbidities. Class II patients are either systemically unwell or have a comorbidity that may complicate or delay resolution of infection. Class III patients have significant systemic upset or limb-threatening infections due to vascular compromise. Class IV patients have sepsis syndrome or a severe life-threatening infection such as necrotising fasciitis.

Understanding Cellulitis: Symptoms, Diagnosis, and Treatment

Cellulitis is a common skin infection caused by Streptococcus pyogenes or Staphylococcus aureus. It is characterized by inflammation of the skin and subcutaneous tissues, usually on the shins, accompanied by erythema, pain, swelling, and sometimes fever. The diagnosis of cellulitis is based on clinical features, and no further investigations are required in primary care. However, bloods and blood cultures may be requested if the patient is admitted and septicaemia is suspected.

To guide the management of patients with cellulitis, NICE Clinical Knowledge Summaries recommend using the Eron classification. Patients with Eron Class III or Class IV cellulitis, severe or rapidly deteriorating cellulitis, very young or frail patients, immunocompromised patients, patients with significant lymphoedema, or facial or periorbital cellulitis (unless very mild) should be admitted for intravenous antibiotics. Patients with Eron Class II cellulitis may not require admission if the facilities and expertise are available in the community to give intravenous antibiotics and monitor the patient.

The first-line treatment for mild/moderate cellulitis is flucloxacillin, while clarithromycin, erythromycin (in pregnancy), or doxycycline is recommended for patients allergic to penicillin. Patients with severe cellulitis should be offered co-amoxiclav, cefuroxime, clindamycin, or ceftriaxone. Understanding the symptoms, diagnosis, and treatment of cellulitis is crucial for effective management and prevention of complications.

Before initiating an ACE inhibitor in patients with heart failure with a reduced ejection fraction, it is recommended to seek specialist advice if the potassium level is above 5 mmol/L. The current NICE CKS guidance suggests starting bisoprolol and ramipril for such patients. However, if the potassium level is high, it is advisable to repeat the urea and electrolytes in 2-3 weeks and seek specialist advice before starting an ACE inhibitor. As the patient is asymptomatic, increasing the dose of furosemide would not be beneficial. There is no need for same-day medical assessment as the patient is currently stable. Although bendroflumethiazide may be suitable for hypertension, NICE CKS recommends ACEi for heart failure treatment.

Angiotensin-converting enzyme (ACE) inhibitors are commonly used as the first-line treatment for hypertension and heart failure in younger patients. However, they may not be as effective in treating hypertensive Afro-Caribbean patients. ACE inhibitors are also used to treat diabetic nephropathy and prevent ischaemic heart disease. These drugs work by inhibiting the conversion of angiotensin I to angiotensin II and are metabolized in the liver.

While ACE inhibitors are generally well-tolerated, they can cause side effects such as cough, angioedema, hyperkalaemia, and first-dose hypotension. Patients with certain conditions, such as renovascular disease, aortic stenosis, or hereditary or idiopathic angioedema, should use ACE inhibitors with caution or avoid them altogether. Pregnant and breastfeeding women should also avoid these drugs.

Patients taking high-dose diuretics may be at increased risk of hypotension when using ACE inhibitors. Therefore, it is important to monitor urea and electrolyte levels before and after starting treatment, as well as any changes in creatinine and potassium levels. Acceptable changes include a 30% increase in serum creatinine from baseline and an increase in potassium up to 5.5 mmol/l. Patients with undiagnosed bilateral renal artery stenosis may experience significant renal impairment when using ACE inhibitors.

The current NICE guidelines recommend using a flow chart to manage hypertension, with ACE inhibitors as the first-line treatment for patients under 55 years old. However, individual patient factors and comorbidities should be taken into account when deciding on the best treatment plan.
