Managing Insulin Use in Unwell Diabetic Patients

When it comes to managing diabetic patients taking insulin, Diabetes Specialist Nurses (DSNs) play a crucial role. However, as a healthcare professional, you may not always have exposure to this type of clinical problem, which can lead to de-skilling. Additionally, the Royal College of General Practitioners (RCGP) has identified this area as a particular weakness in past AKT exams, making it important to stay up-to-date on the topic.

One key aspect of counselling diabetic patients who have started insulin is knowing what to do if they become unwell. For type I diabetics, it is essential to check their blood glucose and ketone levels regularly, at least every 4 hours. If the blood glucose level is less than 13 mmol/L and there are no ketones present in the urine (or ketone levels are less than 1.5 mmol/L on blood ketone testing), then insulin should be taken as normal. However, if the blood glucose level is greater than 13 mmol/L and urinary ketones are present (or blood ketone level greater than 1.5mmol/L), then insulin adjustment is necessary. In such cases, the patient requires an additional 10% of their daily insulin dose as rapid-acting insulin every 4 hours, followed by 4-hourly glucose and ketone monitoring to guide ongoing management.

The most likely diagnosis for this man with biochemical evidence of hypothyroidism and raised anti-TPO antibodies is Hashimoto’s thyroiditis, which is characterized by hypothyroidism, goitre, and anti-TPO antibodies. Exophthalmos, hypercalcaemia, and onycholysis are not typically associated with Hashimoto’s thyroiditis, but rather with other thyroid disorders such as Graves’ disease.

Understanding Hashimoto’s Thyroiditis

Hashimoto’s thyroiditis is a chronic autoimmune disorder that affects the thyroid gland. It is more common in women and is typically associated with hypothyroidism, although there may be a temporary period of thyrotoxicosis during the acute phase. The condition is characterized by a firm, non-tender goitre and the presence of anti-thyroid peroxidase (TPO) and anti-thyroglobulin (Tg) antibodies.

Hashimoto’s thyroiditis is often associated with other autoimmune conditions such as coeliac disease, type 1 diabetes mellitus, and vitiligo. Additionally, there is an increased risk of developing MALT lymphoma with this condition. It is important to note that many causes of hypothyroidism may have an initial thyrotoxic phase, as shown in the Venn diagram. Understanding the features and associations of Hashimoto’s thyroiditis can aid in its diagnosis and management.

Notalgia paraesthetica is a condition that causes chronic itching or tingling on the medial border of the scapula. This can lead to the development of post-inflammatory hyperpigmentation due to repeated rubbing and scratching of the affected area. The exact cause of this sensory neuropathy is not fully understood.

Causes of Pruritus

Pruritus, commonly known as itching, can be caused by various underlying conditions. Liver disease, often associated with a history of alcohol excess, can present with stigmata of chronic liver disease such as spider naevi, bruising, palmar erythema, and gynaecomastia. Evidence of decompensation such as ascites, jaundice, and encephalopathy may also be present. Iron deficiency anaemia can cause pallor and other signs such as koilonychia, atrophic glossitis, post-cricoid webs, and angular stomatitis. Pruritus after a warm bath and a ruddy complexion may indicate polycythaemia. Gout and peptic ulcer disease can also cause itching. Chronic kidney disease may present with lethargy, pallor, oedema, weight gain, hypertension, lymphadenopathy, splenomegaly, hepatomegaly, and fatigue. Other causes of pruritus include hyper- and hypothyroidism, diabetes, pregnancy, senile pruritus, urticaria, and skin disorders such as eczema, scabies, psoriasis, and pityriasis rosea. It is important to identify the underlying cause of pruritus in order to provide appropriate treatment.

Degenerative cervical myelopathy (DCM) is often misdiagnosed as carpal tunnel syndrome (CTS) in patients who undergo surgery for the former. This highlights the importance of considering DCM as a differential diagnosis in patients suspected to have CTS.

CTS is a peripheral nervous system disorder that results from compression of the median nerve at the wrist within the carpal tunnel. It affects only the aspects of the hand innervated by the median nerve, including sensation and motor function. Symptoms typically include intermittent pain or parasthesiae, and motor signs are less commonly seen.

Tests such as Tinels and Phalens can be positive in CTS, but they are not always reliable. In contrast, examination features in focal central nervous system disorders like DCM have low sensitivity but high specificity. DCM affects the sensory, motor, and autonomic nervous systems from the neck downwards, and motor signs are typically upper motor neuron signs such as increased tone, hyper-reflexia, and pyramidal weakness.

Detecting early DCM can be challenging, as the neurological signs are often subtle initially but likely to worsen over time. Therefore, a high index of suspicion, comprehensive neurological examination, and monitoring for progression are required.

Degenerative cervical myelopathy (DCM) is a condition that has several risk factors, including smoking, genetics, and certain occupations that expose individuals to high axial loading. The symptoms of DCM can vary in severity and may include pain, loss of motor function, loss of sensory function, and loss of autonomic function. Early symptoms may be subtle and difficult to detect, but as the condition progresses, symptoms may worsen or new symptoms may appear. An MRI of the cervical spine is the gold standard test for diagnosing cervical myelopathy. All patients with DCM should be urgently referred to specialist spinal services for assessment and treatment. Decompressive surgery is currently the only effective treatment for DCM, and early treatment offers the best chance of a full recovery. Physiotherapy should only be initiated by specialist services to prevent further spinal cord damage.

Treatment Options and Risks for Obstructive Sleep Apnoea

Obstructive sleep apnoea (OSA) is a condition that affects breathing during sleep, leading to interrupted sleep and daytime fatigue. In the UK, the Uvulopalatopharyngoplasty (UPPP) treatment is used for simple snoring, while in the USA, it is used to treat OSA with a success rate of around 65%. Tonsillectomy can also benefit some cases. However, successful treatment with continuous positive airways pressure (CPAP) is the most effective way to reduce the risk of road traffic accidents (RTA) to normal levels and doesn’t exclude the sufferer from holding any type of driving licence. The risk of RTA, untreated, is estimated to be eight times normal. OSA is also associated with hypothyroidism and acromegaly, according to a study published in the Medicine Journal in May 2008. It is important to consider the various treatment options and risks associated with OSA to manage the condition effectively.

If a patient experiences an increase in serum creatinine after starting an ACE-inhibitor like ramipril, it may indicate renal artery stenosis. Other signs of this condition include refractory hypertension and recurrent pulmonary edema with normal left ventricular function. A normal urine dip makes options 1, 2, and 3 unlikely, and there are no symptoms of cancer, infection, or diabetes. While polycystic kidney disease is a possibility, it is inherited in an autosomal dominant manner and typically presents with hypertension, kidney stones, haematuria, or an abdominal mass. However, given the patient’s history and lack of family history of renal disease, renal artery stenosis is the more likely diagnosis.

Chronic kidney disease (CKD) is a condition where the kidneys are not functioning properly. To estimate renal function, serum creatinine levels are often used, but this may not be accurate due to differences in muscle. Therefore, formulas such as the Modification of Diet in Renal Disease (MDRD) equation are used to estimate the glomerular filtration rate (eGFR). The MDRD equation takes into account serum creatinine, age, gender, and ethnicity. However, factors such as pregnancy, muscle mass, and recent red meat consumption may affect the accuracy of the result.

CKD can be classified based on the eGFR. Stage 1 CKD is when the eGFR is greater than 90 ml/min, but there are signs of kidney damage on other tests. If all kidney tests are normal, there is no CKD. Stage 2 CKD is when the eGFR is between 60-90 ml/min with some sign of kidney damage. Stage 3a and 3b CKD are when the eGFR is between 45-59 ml/min and 30-44 ml/min, respectively, indicating a moderate reduction in kidney function. Stage 4 CKD is when the eGFR is between 15-29 ml/min, indicating a severe reduction in kidney function. Stage 5 CKD is when the eGFR is less than 15 ml/min, indicating established kidney failure, and dialysis or a kidney transplant may be necessary. It is important to note that normal U&Es and no proteinuria are required for a diagnosis of CKD.

Blood stained discharge from the nipple is most commonly associated with an intraductal papilloma, which is a benign tumor that develops within the milk ducts of the breast. Surgical excision is the recommended treatment for papillomas, with histology performed to rule out any signs of breast cancer.

Breast fat necrosis, on the other hand, is typically caused by trauma and presents as a firm lump in the breast tissue. It is not associated with nipple discharge and usually resolves on its own.

Fibroadenomas are another type of benign breast lump that are small, non-tender, and mobile. They do not cause nipple discharge and do not require treatment.

Mammary duct ectasia is a condition where the breast ducts become dilated, often leading to blockage. It is most common in menopausal women and can cause nipple discharge, although this is typically thick, non-bloody, and green in color. Surgery may be necessary in some cases.

While pituitary prolactinoma is a possible cause of nipple discharge, it typically presents as bilateral and non-bloodstained. Larger prolactinomas can also cause vision problems due to pressure on the optic chiasm.

Understanding Nipple Discharge: Causes and Assessment

Nipple discharge is a common concern among women, and it can be caused by various factors. Physiological discharge may occur during breastfeeding, while galactorrhea may be triggered by emotional events or certain medications. Hyperprolactinemia, pituitary tumors, mammary duct ectasia, and intraductal papilloma are other possible causes of nipple discharge.

To assess patients with nipple discharge, a breast examination should be conducted to determine the presence of a mass lesion. If a mass is detected, triple assessment is recommended to evaluate the condition. Reporting of investigations should follow a system that uses a prefix denoting the type of investigation, such as M for mammography, followed by a numerical code indicating the findings.

For non-malignant nipple discharge, endocrine disease should be excluded, and smoking cessation advice may be given for duct ectasia. In severe cases of duct ectasia, total duct excision may be necessary. Nipple cytology is generally unhelpful in diagnosing the cause of nipple discharge.

Understanding the causes and assessment of nipple discharge is crucial in providing appropriate management and treatment for patients. Proper evaluation and reporting of investigations can help in identifying any underlying conditions and determining the best course of action.

According to the National Osteoporosis Guideline Group and NICE guidelines, individuals with osteoporosis who are undergoing treatment with alendronate should have their 10 year fracture risk evaluated again after 5 years. After this point, it may be appropriate to discontinue treatment, although this decision should be made on a case-by-case basis. Patients who are over 75, have a history of hip or vertebral fracture, have experienced any low trauma fracture while on treatment, or are still taking steroid therapy should continue with their treatment.

Osteoporosis is a condition that weakens bones, making them more prone to fractures. The National Institute for Health and Care Excellence (NICE) has updated its guidelines on the management of osteoporosis in postmenopausal women. Treatment is recommended for women who have confirmed osteoporosis following fragility fractures. Vitamin D and calcium supplements should be offered to all women unless they have adequate intake. Alendronate is the first-line treatment, but if patients cannot tolerate it, risedronate or etidronate may be given. Strontium ranelate and raloxifene are recommended if bisphosphonates cannot be taken. Treatment criteria for patients not taking alendronate are complex and based on age, T-score, and risk factors. Bisphosphonates have been shown to reduce the risk of fractures, while vitamin D and calcium supplements have a poor evidence base. Raloxifene, strontium ranelate, and denosumab are other treatment options, but they have potential side effects and should only be prescribed by specialists. Hormone replacement therapy is no longer recommended for osteoporosis prevention due to concerns about increased rates of cardiovascular disease and breast cancer. Hip protectors and falls risk assessments may also be considered in the management of high-risk patients.

Treatment for Age-Related Macular Degeneration

The National Institute for Health and Clinical Excellence (NICE) recommends Ranibizumab (Lucentis) as a treatment for certain types of vascular age-related macular degeneration. This treatment involves monthly intravitreal injections for the first three months, followed by monthly monitoring. While this treatment works for one-third of patients, most people maintain their vision.

For dry age-related macular degeneration, psychological support and low vision rehabilitation are recommended. Laser photocoagulation is not an option due to the risk of severe visual loss from laser damage. Smoking cessation is advised, but it is not a treatment.

High-dose vitamin and mineral supplements can slow progression, but they consist of vitamin C, vitamin E, beta-carotene (vitamin A), zinc oxide, and cupric oxide. It is important to note that vitamin D is not included in this treatment.

In summary, there are various treatment options available for age-related macular degeneration, depending on the type and severity of the condition. It is important to consult with a healthcare professional to determine the best course of action.

During acute migraine attacks, patients often experience delayed gastric emptying. Therefore, prokinetic agents like metoclopramide are commonly added to analgesics. Changes in P450 enzyme activity, such as those caused by smoking or drinking, are unlikely to have a significant impact on the metabolism of paracetamol.

Managing Migraines: Guidelines and Treatment Options

Migraines can be debilitating and affect a significant portion of the population. To manage migraines, it is important to understand the different treatment options available. The National Institute for Health and Care Excellence (NICE) has provided guidelines for the management of migraines.

For acute treatment, a combination of an oral triptan and an NSAID or paracetamol is recommended as first-line therapy. For young people aged 12-17 years, a nasal triptan may be preferred. If these measures are not effective or not tolerated, a non-oral preparation of metoclopramide or prochlorperazine may be offered, along with a non-oral NSAID or triptan.

Prophylaxis should be considered if patients are experiencing two or more attacks per month. NICE recommends either topiramate or propranolol, depending on the patient’s preference, comorbidities, and risk of adverse events. Propranolol is preferred in women of childbearing age as topiramate may be teratogenic and reduce the effectiveness of hormonal contraceptives. Acupuncture and riboflavin may also be effective in reducing migraine frequency and intensity.

For women with predictable menstrual migraines, frovatriptan or zolmitriptan may be used as a type of mini-prophylaxis. Specialists may also consider candesartan or monoclonal antibodies directed against the calcitonin gene-related peptide (CGRP) receptor, such as erenumab. However, pizotifen is no longer recommended due to common adverse effects such as weight gain and drowsiness.

It is important to exercise caution with young patients as acute dystonic reactions may develop. By following these guidelines and considering the various treatment options available, migraines can be effectively managed and their impact on daily life reduced.

Common Head and Neck Symptoms and Referral Guidelines

The following are common head and neck symptoms and the appropriate referral guidelines:

1. Discrete slow-growing lump in the right parotid gland: Any unexplained lump in the head or neck requires a 2-week rule referral. A discrete, persistent, unilateral lump in the parotid gland requires an urgent referral, imaging, and further investigation to determine the nature of the mass.

2. Solitary, painful ulcer on the oral mucosa, of 1-week duration: This is most likely to be an aphthous ulcer. An unexplained oral ulceration lasting more than three weeks, or an unexplained neck lump, would warrant a 2-week wait referral.

3. A 7-day history of hoarseness and sore throat: Patients over the age of 45 with persistent unexplained hoarseness should be referred using the cancer pathway. After seven days, this is most likely to be an upper respiratory tract infection.

4. Diffuse multinodular thyroid swelling: For suspected thyroid cancer, the single referral criterion is an ‘unexplained thyroid lump’. The most likely diagnosis in this patient is a multinodular goitre.

5. Nasal obstruction and bilateral grey swellings visible by nasal speculum: Bilateral nasal swellings of this description are almost certainly polyps. These can initially be managed in primary care. Unilateral polyps should be referred to the ear, nose and throat clinic.

Head and Neck Symptoms and Referral Guidelines

The man’s symptoms suggest bacterial sinusitis, as he has experienced a double sickening where his symptoms initially improved but then suddenly worsened. This is often caused by a secondary bacterial infection following a viral rhinosinusitis. The presence of a fever and purulent discharge seen on rhinoscopy further support this diagnosis.

Trigeminal neuralgia would not cause a fever, while sialadenitis would result in swelling of only one salivary gland. Cavernous sinus thrombosis is a rare complication of bacterial sinusitis and is not likely in this case.

Acute sinusitis is a condition where the mucous membranes of the paranasal sinuses become inflamed. This inflammation is usually caused by infectious agents such as Streptococcus pneumoniae, Haemophilus influenza, and rhinoviruses. Certain factors can predispose individuals to this condition, including nasal obstruction, recent local infections, swimming/diving, and smoking. Symptoms of acute sinusitis include facial pain, nasal discharge, and nasal obstruction. Treatment options include analgesia, intranasal decongestants or nasal saline, and intranasal corticosteroids. Oral antibiotics may be necessary for severe presentations, but they are not typically required. In some cases, an initial viral sinusitis can worsen due to secondary bacterial infection, which is known as double-sickening.

Differentiating Measles from Other Childhood Illnesses

Measles is a highly contagious viral illness that typically presents with a prodrome of coryzal symptoms, dry cough, conjunctivitis, and fever before the appearance of a rash. Koplik’s spots may also be present on the buccal mucosa. However, other childhood illnesses can present with similar symptoms, making it important to differentiate between them. Rubella, for example, has a longer incubation period and is typically milder with no significant respiratory symptoms. Parvovirus B19 can mimic rubella with its slapped-cheek appearance. Infectious mononucleosis may present with a sore throat and lymphadenopathy, but any rash is fine and transient. Mumps may rarely cause a rash, but other symptoms are more prominent. It is crucial to accurately diagnose these illnesses to provide appropriate treatment and prevent further spread of infection.

Recommended Levels of Homocysteine

Homocysteine is a naturally occurring amino acid in the body that can be harmful in high levels. The upper limit of normal for homocysteine was previously set at 0.42 µmol/L, with reducing levels below that considered acceptable. However, recent guidelines have recommended even lower levels, with most sources suggesting levels below 0.36 µmol/L and the latest guidelines aiming for 0.30 µmol/L. It is important to monitor homocysteine levels and take steps to reduce them if they are too high, as elevated levels have been linked to an increased risk of cardiovascular disease and other health issues.

Giant Cell Temporal Arteritis: Urgent Management Required

This patient’s history strongly suggests giant cell temporal arteritis (GCA), a medical emergency that requires urgent management. While ophthalmologists may be involved in the management of GCA, their involvement is only necessary if the condition is affecting the patient’s vision. In this scenario, the patient’s vision is not affected.

The recommended course of action is to start the patient on 40-60mg of prednisolone per day (for patients without visual symptoms) and refer them urgently to a physician, typically a Rheumatologist. It is important to note that national guidance should be followed, rather than local variations, when assessing patients in an exam setting. Shared care is recommended, and patients may require treatment for several years.

In addition to steroids, aspirin and PPIs are recommended. However, long-term treatment with oral steroids can increase the risk of osteoporosis, which should be assessed. For more information on national guidance and associated information, CKS provides a comprehensive summary of GCA management.

Given the patient’s normal examination and blood counts, the most suitable option would be to provide first aid measures for nosebleeds. It is important to note that Naseptin cream contains peanut oil, which is contraindicated for this patient due to her anaphylaxis to peanuts.

Performing cautery of a bleeding focus can be considered by a primary care practitioner with experience, but only if a bleeding focus is identified and not bilaterally to avoid perforation. However, since no abnormalities were found during examination, cautery is not recommended.

If the clinician is uncertain about management, referring the patient to an ENT surgeon is a viable option. This may not be the best initial management, but it is appropriate if the issue recurs.

If the bleeding persists despite appropriate first aid measures, it is recommended to advise the patient to go to the emergency department. The first aid measures would include applying pressure below the nasal bones on the nasal cartilage while sitting forward for 20 minutes.

Understanding Epistaxis: Causes and Management

Epistaxis, commonly known as nosebleeds, can be categorized into anterior and posterior bleeds. Anterior bleeds usually have a visible source of bleeding and occur due to an injury to the network of capillaries that form Kiesselbach’s plexus. On the other hand, posterior haemorrhages tend to be more severe and originate from deeper structures. They are more common in older patients and pose a higher risk of aspiration and airway obstruction.

Most cases of epistaxis are benign and self-limiting. However, exacerbation factors such as nose picking, nose blowing, trauma to the nose, insertion of foreign bodies, bleeding disorders, and immune thrombocytopenia can trigger nosebleeds. Other causes include hereditary haemorrhagic telangiectasia, granulomatosis with polyangiitis, and cocaine use.

If the patient is haemodynamically stable, bleeding can be controlled with first aid measures such as sitting with their torso forward and their mouth open, pinching the cartilaginous area of the nose firmly for at least 20 minutes, and using a topical antiseptic to reduce crusting and the risk of vestibulitis. If bleeding persists, cautery or packing may be necessary. Cautery should be used initially if the source of the bleed is visible, while packing may be used if cautery is not viable or the bleeding point cannot be visualized.

Patients that are haemodynamically unstable or compromised should be admitted to the emergency department, while those with a bleed from an unknown or posterior source should be admitted to the hospital. Epistaxis that has failed all emergency management may require sphenopalatine ligation in theatre. Overall, understanding the causes and management of epistaxis is crucial in providing effective care for patients experiencing nosebleeds.

Antiphospholipid syndrome is the most probable diagnosis due to the paradoxical occurrence of prolonged APTT and low platelets.

Antiphospholipid syndrome is a condition that can be acquired and is characterized by a higher risk of both venous and arterial thromboses, recurrent fetal loss, and thrombocytopenia. It can occur as a primary disorder or secondary to other conditions, with systemic lupus erythematosus being the most common. One important point to remember for exams is that antiphospholipid syndrome causes a paradoxical increase in the APTT due to an ex-vivo reaction of lupus anticoagulant autoantibodies with phospholipids involved in the coagulation cascade.

Other features of antiphospholipid syndrome include livedo reticularis, pre-eclampsia, and pulmonary hypertension. It is associated with other autoimmune disorders and lymphoproliferative disorders, as well as rare cases of phenothiazines. Management of antiphospholipid syndrome is based on EULAR guidelines, with primary thromboprophylaxis and low-dose aspirin being recommended. For secondary thromboprophylaxis, lifelong warfarin with a target INR of 2-3 is recommended for initial venous thromboembolic events, while recurrent venous thromboembolic events require lifelong warfarin and may benefit from the addition of low-dose aspirin and an increased target INR of 3-4. Arterial thrombosis should also be treated with lifelong warfarin with a target INR of 2-3.

The recommended initial treatment for migraines during pregnancy is paracetamol, which is likely to be effective for this patient experiencing a pulsating headache on one side. Aspirin and ibuprofen should be avoided in the third trimester due to the risk of fetal ductal arteriosus closure. Sumatriptan is not considered first-line and should only be used if the potential benefits outweigh the risks, according to the manufacturer’s advice.

Managing Migraine in Relation to Hormonal Factors

Migraine is a common neurological condition that affects many people, particularly women. Hormonal factors such as pregnancy, contraception, and menstruation can have an impact on the management of migraine. In 2008, the Scottish Intercollegiate Guidelines Network (SIGN) produced guidelines on the management of migraine, which provide useful information on how to manage migraine in relation to these hormonal factors.

When it comes to migraine during pregnancy, paracetamol is the first-line treatment, while NSAIDs can be used as a second-line treatment in the first and second trimester. However, aspirin and opioids such as codeine should be avoided during pregnancy. If a patient has migraine with aura, the combined oral contraceptive (COC) pill is absolutely contraindicated due to an increased risk of stroke. Women who experience migraines around the time of menstruation can be treated with mefenamic acid or a combination of aspirin, paracetamol, and caffeine. Triptans are also recommended in the acute situation. Hormone replacement therapy (HRT) is safe to prescribe for patients with a history of migraine, but it may make migraines worse.

In summary, managing migraine in relation to hormonal factors requires careful consideration and appropriate treatment. The SIGN guidelines provide valuable information on how to manage migraine in these situations, and healthcare professionals should be aware of these guidelines to ensure that patients receive the best possible care.

The patient is experiencing delusional parasitosis, which is a fixed false belief that they are infested with ‘bugs’. This is consistent with the symptoms of ‘Morgellons’, which is a form of delusional parasitosis. The reported fibers or materials are often found to be common household or clothing materials, and the skin lesions are likely caused by repetitive picking. The hypopigmented patches are healed lesions, and the area between the scapula is spared, indicating that the patient is unable to reach that area and no lesions were found there. This is not indicative of body dysmorphic disorder, conversion disorder, or somatic symptom disorder.

Understanding Delusional Parasitosis

Delusional parasitosis is a condition that is not commonly seen, but it can be quite distressing for those who experience it. Essentially, it involves a person having a false belief that they are infested with some kind of bug or parasite, such as worms, mites, or bacteria. This belief is fixed and unshakeable, even in the face of evidence to the contrary.

It is important to note that delusional parasitosis can occur on its own, but it may also be a symptom of other psychiatric conditions. Despite the delusion, many people with this condition are otherwise functional and able to carry out their daily activities. However, the belief can cause significant anxiety and distress, and may lead to behaviors such as excessive cleaning or avoidance of certain places or activities. Treatment for delusional parasitosis typically involves a combination of medication and therapy to address the underlying psychiatric condition and help the person manage their symptoms.

Identifying ‘Alarm’ Symptoms in Primary Care Patients with Dyspepsia

When evaluating patients with dyspepsia in primary care, it is crucial to identify any ‘alarm’ symptoms or ‘red flags’ that may indicate a more serious underlying condition. By taking a targeted history and performing a thorough examination, healthcare providers can determine which patients require urgent referral for further investigation and which can be managed in the community.

In the case of a male patient over 55-years-old with persistent unexplained dyspepsia, signs of anaemia (such as shortness of breath, pallor, and angular stomatitis), and a history of smoking, these ‘alarm’ features suggest the need for urgent referral for endoscopy to investigate the possibility of upper gastrointestinal (GI) cancer. The June 2015 update recommends a 2-week referral for patients over 55 with weight loss, abdominal pain, reflux, or dyspepsia. By identifying and acting on ‘alarm’ symptoms, healthcare providers can ensure timely diagnosis and treatment of potentially serious conditions.

Continuous Subcutaneous Infusions in Palliative Care: Medications to Consider and Avoid

Continuous subcutaneous infusions are a popular method of delivering medications in palliative care when other modes of delivery are no longer suitable. This method involves administering medication into the fatty tissue under the skin, providing constant dosing over a calculated period of time. Commonly used drugs include opioids, antiemetics, anticholinergics, sedatives, and others such as dexamethasone, ketorolac, ketamine, and octreotide. However, some medications are not suitable for subcutaneous infusion. Amoxicillin can damage tissue and is unlikely to have a role in end-of-life care. Chlorpromazine and prochlorperazine must not be given by this route as they may cause tissue necrosis. Diazepam can also cause tissue necrosis and should be avoided, with midazolam being the preferred benzodiazepine for subcutaneous infusion if needed. It is important to consider the suitability of medications for continuous subcutaneous infusion in palliative care to ensure safe and effective treatment.

The patient is experiencing acute dystonia, which is a sustained muscle contraction resulting in torticollis or oculogyric crisis. This is likely due to the recent initiation of a typical antipsychotic medication, specifically haloperidol. Torticollis, or a wry neck, is diagnosed when there is unilateral pain and deviation of the neck, restricted range of motion, and pain upon palpation.

While neuroleptic malignant syndrome is a medical emergency that can occur in patients taking antipsychotics, this patient’s mild tachycardia is likely due to pain rather than altered mental state, generalised rigidity, fever, fluctuating blood pressure, and high temperature, which are the hallmark symptoms of this condition. However, it should still be considered in patients taking antipsychotics.

Another example of acute dystonia is an oculogyric crisis, which involves sustained upward deviation of the eyes, clenched jaw, and hyperextension of the back/neck with torticollis. However, since the patient doesn’t exhibit any facial signs or symptoms, torticollis alone is the more appropriate diagnosis.

Tardive dyskinesia is a condition that occurs in patients on long-term typical antipsychotics and is characterised by uncontrolled facial movements, such as lip-smacking.

Antipsychotics are a type of medication used to treat schizophrenia, psychosis, mania, and agitation. They are divided into two categories: typical and atypical antipsychotics. The latter were developed to address the extrapyramidal side-effects associated with the first generation of typical antipsychotics. Typical antipsychotics work by blocking dopaminergic transmission in the mesolimbic pathways through dopamine D2 receptor antagonism. However, they are known to cause extrapyramidal side-effects such as Parkinsonism, acute dystonia, akathisia, and tardive dyskinesia. These side-effects can be managed with procyclidine. Other side-effects of typical antipsychotics include antimuscarinic effects, sedation, weight gain, raised prolactin, impaired glucose tolerance, neuroleptic malignant syndrome, reduced seizure threshold, and prolonged QT interval. The Medicines and Healthcare products Regulatory Agency has issued specific warnings when antipsychotics are used in elderly patients due to an increased risk of stroke and venous thromboembolism.

Conversion disorder is a condition that often results in the loss of motor or sensory function and is believed to be triggered by stress.

Unexplained Symptoms in Psychiatry

In psychiatry, there are several terms used to describe patients who present with physical or psychological symptoms for which no organic cause can be found. Somatisation disorder is characterized by the presence of multiple physical symptoms that persist for at least two years, and the patient refuses to accept reassurance or negative test results. Illness anxiety disorder, also known as hypochondriasis, involves a persistent belief in the presence of an underlying serious disease, such as cancer, despite negative test results. Conversion disorder typically involves the loss of motor or sensory function, and the patient doesn’t consciously feign the symptoms or seek material gain. Dissociative disorder involves the process of separating off certain memories from normal consciousness, and may present with psychiatric symptoms such as amnesia, fugue, or stupor. Factitious disorder, also known as Munchausen’s syndrome, involves the intentional production of physical or psychological symptoms, while malingering refers to the fraudulent simulation or exaggeration of symptoms for financial or other gain. These terms help clinicians to better understand and diagnose patients with unexplained symptoms.

Identifying and Treating Giardia: Symptoms and Treatment

Giardia is a parasitic infection that should be suspected if symptoms of traveller’s diarrhoea persist for more than 10 days or if symptoms begin after returning home. Weight loss may also be present. However, if diarrhoea lasts for less than a week, it is likely caused by something else, such as norovirus. Vomiting is a common symptom of most diarrhoeal illnesses, except for shigella and giardia. Both Salmonella and Shigella infections may also cause high fever. Treatment for Giardia involves the use of metronidazole.

Initial Management for Suspected Pancreatic Cancer: Abdominal CT Scan

When a patient over 60 years old presents with weight loss and abdominal pain, an urgent direct-access CT scan should be considered to assess for pancreatic cancer. Other symptoms that may indicate pancreatic cancer include diarrhea, back pain, nausea, vomiting, constipation, and new-onset diabetes. Patients with pancreatic cancer typically report anorexia, malaise, fatigue, mid-epigastric or back pain, and weight loss. The pain may be unrelenting and worse when lying flat.

The most characteristic sign of pancreatic carcinoma of the head of the pancreas is painless obstructive jaundice. Migratory thrombophlebitis and venous thrombosis also occur with higher frequency in patients with pancreatic cancer and may be the first presentation.

While the CA 19-9 antigen is elevated in 75-80% of patients with pancreatic carcinoma, it is not recommended for screening. An abdominal ultrasound scan may reveal a pancreatic malignancy, but a CT scan is the preferred imaging that should be carried out urgently.

Direct-access upper GI endoscopy may be appropriate for patients over 55 years old with weight loss and upper abdominal pain, reflux, or dyspepsia. However, in this case, an urgent CT scan is the most appropriate initial investigation due to the elevated alkaline phosphatase suggesting biliary obstruction. Checking ferritin levels may not be helpful in ruling in or out pancreatic cancer.

Initial Management for Suspected Pancreatic Cancer: Abdominal CT Scan

Animal bites are a common occurrence in everyday practice, with dogs and cats being the most frequent culprits. These bites are usually caused by multiple types of bacteria, with Pasteurella multocida being the most commonly isolated organism. To manage these bites, it is important to cleanse the wound thoroughly. Puncture wounds should not be sutured unless there is a risk of cosmesis. The current recommendation is to use co-amoxiclav, but if the patient is allergic to penicillin, doxycycline and metronidazole are recommended.

On the other hand, human bites can cause infections from a variety of bacteria, including both aerobic and anaerobic types. Common organisms include Streptococci spp., Staphylococcus aureus, Eikenella, Fusobacterium, and Prevotella. To manage these bites, co-amoxiclav is also recommended. It is important to consider the risk of viral infections such as HIV and hepatitis C when dealing with human bites.

Peri-oral dermatitis cannot be treated with potent steroids as they are not effective. Emollients are also not recommended for improving the condition. Patients are advised to stop using all face care products until the flare-up of peri-oral dermatitis has subsided. The British Association of Dermatology (BAD) provides a useful leaflet on this condition that should be consulted.

Understanding Periorificial Dermatitis

Periorificial dermatitis is a skin condition that is commonly observed in women between the ages of 20 and 45 years old. The use of topical corticosteroids, and to a lesser extent, inhaled corticosteroids, is often linked to the development of this condition. The symptoms of periorificial dermatitis include the appearance of clustered erythematous papules, papulovesicles, and papulopustules, which are typically found in the perioral, perinasal, and periocular regions. However, the skin immediately adjacent to the vermilion border of the lip is usually spared.

When it comes to managing periorificial dermatitis, it is important to note that steroids may actually worsen the symptoms. Instead, the condition should be treated with either topical or oral antibiotics. By understanding the features and management of periorificial dermatitis, individuals can take the necessary steps to address this condition and improve their skin health.

Treatment Options for Seizures in Palliative Care Patients

Seizures are a common occurrence in palliative care patients, often caused by brain tumors or biochemical imbalances. Advance care planning is crucial to prevent unwanted hospital admissions. Here are some treatment options:

1. Intravenous Lorazepam: Administer 4 mg by slow injection if resuscitation equipment is available.

2. Midazolam or Diazepam: Buccal or subcutaneous administration of 10 mg midazolam or 10 mg rectal solution or per stoma of diazepam is recommended as first-line treatment. If seizure activity persists, the dose can be repeated once after 10-20 minutes.

3. Intravenous Phenytoin: 15 mg/kg (maximum total dose 1 g) can be used for refractory seizures, but requires a filter and cardiac monitoring.

4. Intramuscular Diamorphine: This is not a suitable treatment for seizure activity.

5. Intramuscular Diazepam: Diazepam is a reasonable first-line treatment, but the 10 mg dose should be administered per rectum (or via a stoma if appropriate), and not intramuscularly.

6. Intramuscular Phenobarbital: Phenobarbital 100-200 mg intramuscularly would only be used for a protracted seizure not responding to first-line treatment, under specialist supervision.

The Importance of Prompt Diagnosis and Treatment for Giant Cell Arteritis

Giant cell arteritis (GCA) is a serious condition that can lead to irreversible visual loss if left untreated. Symptoms include headache, scalp tenderness, and jaw claudication. While abnormalities in the temporal artery are only found in about 30% of patients on examination, a normal examination doesn’t exclude the condition.

Immediate treatment with high-dose steroids is recommended by the National Institute for Health and Care Excellence (NICE) on suspicion of GCA, and an urgent referral to a specialist, usually a rheumatologist, should be made within 72 hours. Delay in treatment can have serious consequences, so it is important to start treatment promptly.

While a temporal artery biopsy may be necessary to confirm the diagnosis, treatment should not be postponed until this can be arranged. Ultrasound can also be used as a diagnostic tool, which is less invasive. Long-term oral steroids carry risks and side effects, so it is important to confirm the diagnosis with a specialist to ensure that treatment is indicated.

Prompt diagnosis and treatment are crucial in cases of suspected GCA to prevent irreversible visual loss and other serious complications.

Although health promotion is crucial, it falls outside the scope of clinical governance.

Understanding Clinical Governance

Clinical governance is a system that holds NHS organizations accountable for improving the quality of their services and ensuring high standards of care. It creates an environment that fosters clinical excellence and continuous improvement. This system is made up of several components, including education and training, clinical audit, clinical effectiveness, research and development, risk management, and openness. Each of these elements plays a crucial role in ensuring that healthcare providers deliver the best possible care to patients. By implementing clinical governance, NHS organizations can identify areas for improvement, measure their progress, and make changes that benefit patients and staff alike. With a focus on quality and safety, clinical governance is an essential part of modern healthcare.
