Approaches to Managing Dyspepsia in Patients with Gastro-Oesophageal Reflux Disease

Patients with chronic gastro-oesophageal reflux disease (GORD) are at risk of developing Barrett’s oesophagus and oesophageal cancer. Therefore, patients aged 50 years or older with a history of chronic GORD should undergo at least one upper gastrointestinal (GI) endoscopy to screen for these conditions. In younger patients, long-term low-dose proton pump inhibitor (PPI) therapy may be considered, with dose adjustment if necessary. However, ongoing dyspepsia in a patient over 50 years old warrants further investigation to exclude serious pathology. Intermittent high-dose PPI therapy is currently only used in hospital for specific indications. Counselling with false reassurance should be avoided in patients with concerning symptoms.

Reassurance and advice are sufficient for managing nocturnal enuresis in children under 5 years of age. It is important to reassure mothers that bedwetting is still common at the age of 4.

Nocturnal enuresis, or bedwetting, is when a child involuntarily urinates during the night. Most children achieve continence by the age of 3 or 4, so enuresis is defined as the involuntary discharge of urine in a child aged 5 or older without any underlying medical conditions. Enuresis can be primary, meaning the child has never achieved continence, or secondary, meaning the child has been dry for at least 6 months before.

When managing bedwetting, it’s important to look for any underlying causes or triggers, such as constipation, diabetes mellitus, or recent onset UTIs. General advice includes monitoring fluid intake and encouraging regular toileting patterns, such as emptying the bladder before sleep. Reward systems, like star charts, can also be helpful, but should be given for agreed behavior rather than dry nights.

The first-line treatment for bedwetting is an enuresis alarm, which has a high success rate. These alarms have sensor pads that detect wetness and wake the child up to use the toilet. If short-term control is needed, such as for sleepovers, or if the alarm is ineffective or not acceptable to the family, desmopressin may be prescribed. Overall, managing bedwetting involves identifying any underlying causes and implementing strategies to promote continence.

Assessing medications in elderly patients can be challenging, as they may be taking unnecessary or harmful drugs. The STOPP-START Criteria (Gallagher et al., 2008) provides guidance on medications that should be considered for discontinuation in the elderly. In this case, the patient has gout, which can be aggravated by bendroflumethiazide, an outdated thiazide diuretic that is no longer recommended by NICE. Additionally, her blood pressure is well below the target for her age, which is 150/90 mmHg in clinic. Ramipril is a more suitable antihypertensive medication to continue for now, but it may also be discontinued if her blood pressure remains low. The patient requires aspirin and atorvastatin for her ischemic heart disease, and allopurinol for her gout.

NICE Guidelines for Managing Hypertension

Hypertension, or high blood pressure, is a common condition that can lead to serious health problems if left untreated. The National Institute for Health and Care Excellence (NICE) has published updated guidelines for the management of hypertension in 2019. Some of the key changes include lowering the threshold for treating stage 1 hypertension in patients under 80 years old, allowing the use of angiotensin receptor blockers instead of ACE inhibitors, and recommending the use of a calcium channel blocker or thiazide-like diuretic in addition to an ACE inhibitor or angiotensin receptor blocker.

The guidelines also provide a flow chart for the diagnosis and management of hypertension. Lifestyle advice, such as reducing salt intake, caffeine intake, and alcohol consumption, as well as exercising more and losing weight, should not be forgotten and is frequently tested in exams. Treatment options depend on the patient’s age, ethnicity, and other factors, and may involve a combination of drugs.

NICE recommends treating stage 1 hypertension in patients under 80 years old if they have target organ damage, established cardiovascular disease, renal disease, diabetes, or a 10-year cardiovascular risk equivalent to 10% or greater. For patients with stage 2 hypertension, drug treatment should be offered regardless of age. The guidelines also provide step-by-step treatment options, including adding a third or fourth drug if necessary.

New drugs, such as direct renin inhibitors like Aliskiren, may have a role in patients who are intolerant of more established antihypertensive drugs. However, trials have only investigated the fall in blood pressure and no mortality data is available yet. Patients who fail to respond to step 4 measures should be referred to a specialist. The guidelines also provide blood pressure targets for different age groups.

Immediate initiation of insulin is recommended due to the high blood glucose levels and presence of macrosomia. Additionally, it is advisable to consider administering aspirin as there is an elevated risk of pre-eclampsia.

Gestational diabetes is a common medical disorder affecting around 4% of pregnancies. Risk factors include a high BMI, previous gestational diabetes, and family history of diabetes. Screening is done through an oral glucose tolerance test, and diagnostic thresholds have recently been updated. Management includes self-monitoring of blood glucose, diet and exercise advice, and medication if necessary. For pre-existing diabetes, weight loss and insulin are recommended, and tight glycemic control is important. Targets for self-monitoring include fasting glucose of 5.3 mmol/l and 1-2 hour post-meal glucose levels.

The presence of fever, jaundice and right upper quadrant pain is known as Charcot’s cholangitis triad, which indicates an infection of the bile ducts. This patient is likely suffering from ascending cholangitis. Cholecystitis, which is inflammation of the gallbladder, can also cause right upper quadrant pain and may precede ascending cholangitis. While gallstones are a common cause of cholangitis, they can be asymptomatic and are not a diagnosis on their own. Pregnancy is not a likely cause of right upper quadrant pain. Gilbert’s syndrome typically causes mild jaundice only during times of stress and is usually asymptomatic.

Understanding Ascending Cholangitis

Ascending cholangitis is a bacterial infection that affects the biliary tree, with E. coli being the most common culprit. This condition is often associated with gallstones, which can predispose individuals to the infection. Patients with ascending cholangitis may present with Charcot’s triad, which includes fever, right upper quadrant pain, and jaundice. However, this triad is only present in 20-50% of cases. Other common symptoms include hypotension and confusion. In severe cases, Reynolds’ pentad may be observed, which includes the additional symptoms of hypotension and confusion.

To diagnose ascending cholangitis, ultrasound is typically used as a first-line investigation to look for bile duct dilation and stones. Raised inflammatory markers may also be observed. Treatment involves intravenous antibiotics and endoscopic retrograde cholangiopancreatography (ERCP) after 24-48 hours to relieve any obstruction.

Overall, ascending cholangitis is a serious condition that requires prompt diagnosis and treatment. Understanding the symptoms and risk factors associated with this condition can help individuals seek medical attention early and improve their chances of a successful recovery.

Acute viral labyrinthitis presents with sudden horizontal nystagmus, hearing issues, nausea, vomiting, and vertigo. It is typically preceded by a viral infection and can cause hearing loss. Unlike BPPV, it is not associated with hearing loss. A central cause such as a stroke is less likely as the nystagmus is unidirectional and the head impulse test is impaired. Vestibular neuritis has similar symptoms to viral labyrinthitis but does not result in hearing loss.

Labyrinthitis is a condition that involves inflammation of the membranous labyrinth, which affects both the vestibular and cochlear end organs. This disorder can be caused by a viral, bacterial, or systemic disease, with viral labyrinthitis being the most common form. It is important to distinguish labyrinthitis from vestibular neuritis, as the latter only affects the vestibular nerve and does not result in hearing impairment. Labyrinthitis, on the other hand, affects both the vestibular nerve and the labyrinth, leading to vertigo and hearing loss.

The typical age range for presentation of labyrinthitis is between 40-70 years old. Patients usually experience an acute onset of symptoms, including vertigo that is not triggered by movement but worsened by it, nausea and vomiting, hearing loss (which can be unilateral or bilateral), tinnitus, and preceding or concurrent upper respiratory tract infection symptoms. Signs of labyrinthitis include spontaneous unidirectional horizontal nystagmus towards the unaffected side, sensorineural hearing loss, an abnormal head impulse test, and gait disturbance that may cause the patient to fall towards the affected side.

Diagnosis of labyrinthitis is primarily based on the patient’s history and physical examination. While episodes of labyrinthitis are typically self-limiting, medications such as prochlorperazine or antihistamines may help reduce the sensation of dizziness. Overall, it is important to accurately diagnose and manage labyrinthitis to prevent complications and improve the patient’s quality of life.

The patient exhibits a diastolic murmur that is most pronounced over the aortic valve, along with a wide pulse pressure, indicating a diagnosis of aortic regurgitation. Aortic stenosis, on the other hand, would manifest as a systolic murmur with a narrow pulse pressure. Meanwhile, mitral regurgitation would present as a systolic murmur that is most audible over the mitral valve, while mitral stenosis would produce a diastolic murmur that is loudest over the mitral valve and would not result in a wide pulse pressure.

Aortic regurgitation is a condition where the aortic valve of the heart leaks, causing blood to flow in the opposite direction during ventricular diastole. This can be caused by disease of the aortic valve or by distortion or dilation of the aortic root and ascending aorta. In the developing world, rheumatic fever is the most common cause of AR, while in developed countries, calcific valve disease and connective tissue diseases like rheumatoid arthritis and SLE are more common causes. Symptoms of AR include an early diastolic murmur, collapsing pulse, wide pulse pressure, Quincke’s sign, and De Musset’s sign. Echocardiography is used to investigate suspected AR. Management includes medical management of any associated heart failure and surgery for symptomatic patients with severe AR or asymptomatic patients with severe AR who have LV systolic dysfunction.

Acarbose works by inhibiting the enzymes responsible for breaking down carbohydrates, specifically α-glucosidase enzymes found in the small intestine and pancreatic a-amylase. On the other hand, metformin reduces the production of glucose in the liver and increases insulin sensitivity, resulting in increased glucose uptake in peripheral tissues. Unlike sulfonylureas, metformin does not increase insulin secretion and has a lower risk of hypoglycemia. Sulfonylureas, on the other hand, increase insulin secretion by binding to ATP-sensitive K+ channels in pancreatic b-cells, but have no effect on peripheral insulin sensitivity. While the newer glitazones, rosiglitazone and pioglitazone, are not associated with hepatotoxicity, troglitazone, an older glitazone, was withdrawn due to drug-related hepatitis. Pioglitazone is associated with an increased risk of heart failure, bladder cancer, and bone fracture, and should be used with caution in high-risk individuals. Clinicians should regularly review the safety and efficacy of pioglitazone in patients to ensure that only those who benefit continue to receive treatment.

Couples are advised to engage in regular sexual intercourse every 2-3 days for a period of 12 months before seeking referral to a specialist. After this time, fertility testing should be conducted, including semen analysis for the male and mid-luteal progesterone level for the female to confirm ovulation. The use of basal body temperature kits is not recommended as they can increase anxiety and have not been proven effective. However, early referral should be considered for females over 35 years of age, those with a history of amenorrhea or pelvic surgery, and those with abnormal genital examinations. Males with a history of genital surgery, STIs, varicocele, or significant systemic illness should also be referred early.

Infertility is a common issue that affects approximately 1 in 7 couples. It is important to note that around 84% of couples who have regular sexual intercourse will conceive within the first year, and 92% within the first two years. The causes of infertility can vary, with male factor accounting for 30%, unexplained causes accounting for 20%, ovulation failure accounting for 20%, tubal damage accounting for 15%, and other causes accounting for the remaining 15%.

When investigating infertility, there are some basic tests that can be done. These include a semen analysis and a serum progesterone test. The serum progesterone test is done 7 days prior to the expected next period, typically on day 21 for a 28-day cycle. The interpretation of the serum progesterone level is as follows: if it is less than 16 nmol/l, it should be repeated and if it remains consistently low, referral to a specialist is necessary. If the level is between 16-30 nmol/l, it should be repeated, and if it is greater than 30 nmol/l, it indicates ovulation.

It is important to counsel patients on lifestyle factors that can impact fertility. This includes taking folic acid, maintaining a healthy BMI between 20-25, and advising regular sexual intercourse every 2 to 3 days. Additionally, patients should be advised to quit smoking and limit alcohol consumption to increase their chances of conceiving.

Transverse myelitis is not linked to pre-eclampsia.

Pre-eclampsia is a condition that occurs during pregnancy and is characterized by high blood pressure, proteinuria, and edema. It can lead to complications such as eclampsia, neurological issues, fetal growth problems, liver involvement, and cardiac failure. Severe pre-eclampsia is marked by hypertension, proteinuria, headache, visual disturbances, and other symptoms. Risk factors for pre-eclampsia include hypertension in a previous pregnancy, chronic kidney disease, autoimmune disease, diabetes, chronic hypertension, first pregnancy, and age over 40. Aspirin may be recommended for women with high or moderate risk factors. Treatment involves emergency assessment, admission for observation, and medication such as labetalol, nifedipine, or hydralazine. Delivery of the baby is the most important step in management, with timing depending on the individual case.
