Focal aware seizures do not affect consciousness or awareness, and may involve automatic, repetitive actions such as lip smacking.

Epilepsy is classified based on three key features: where seizures begin in the brain, level of awareness during a seizure, and other features of seizures. Focal seizures, previously known as partial seizures, start in a specific area on one side of the brain. The level of awareness can vary in focal seizures, and they can be further classified as focal aware, focal impaired awareness, or awareness unknown. Focal seizures can also be motor, non-motor, or have other features such as aura. Generalized seizures involve networks on both sides of the brain at the onset, and consciousness is lost immediately. They can be further subdivided into motor and non-motor types. Unknown onset is used when the origin of the seizure is unknown. Focal to bilateral seizures start on one side of the brain in a specific area before spreading to both lobes and were previously known as secondary generalized seizures.

Anteroseptal changes in V1-V4 indicate involvement of the left anterior descending artery.
Inferior changes in II, III, and aVF suggest the right coronary artery is affected.
Anterolateral changes in V1-6, I, and aVL indicate the proximal left anterior descending artery is involved.
Lateral changes in I, aVL, and possibly V5-6 suggest the left circumflex artery is affected.
Posterior changes in V1-3 may indicate a posterior infarction, which is confirmed by ST elevation and Q waves in posterior leads (V7-9). This type of infarction is usually caused by the left circumflex artery, but can also be caused by the right coronary artery.
Reciprocal changes of STEMI are typically seen as horizontal ST depression, tall and broad R waves, upright T waves, and a dominant R wave in V2. It is important to note that a new left bundle branch block (LBBB) may indicate acute coronary syndrome.

Overall, understanding the correlation between ECG changes and coronary artery territories is crucial in diagnosing acute coronary syndrome. By identifying the specific changes in the ECG, medical professionals can determine which artery is affected and provide appropriate treatment. Additionally, recognizing the reciprocal changes of STEMI and the significance of a new LBBB can aid in making an accurate diagnosis.

Diagnosing Glandular Fever: Understanding Symptoms and Differential Diagnosis

Glandular fever, also known as infectious mononucleosis, is a viral illness that can cause a range of symptoms, including fever, sore throat, fatigue, and swollen lymph nodes. One common symptom is the development of a maculopapular rash, which can be triggered by taking penicillin. However, it is important to consider other potential diagnoses and rule out conditions such as dermatitis herpetiformis, allergy to penicillin, herpes zoster, and streptococcal throat infection.

To confirm a diagnosis of glandular fever, healthcare providers may perform a full blood count to check for lymphocytosis and atypical lymphocytes. Epstein-Barr virus (EBV) serology may also be tested in certain cases. Treatment for glandular fever is primarily supportive, and patients are advised to avoid contact sports to reduce the risk of splenic rupture.

By understanding the symptoms and differential diagnosis of glandular fever, healthcare providers can accurately diagnose and manage this viral illness.

When a patient experiences progressive dysphagia along with weight loss, it is important to investigate for possible oesophageal carcinoma as this is a common characteristic. Laryngeal nerve damage can also cause hoarseness in patients with this type of cancer. Although achalasia may present with similar symptoms, patients typically have difficulty swallowing both solids and liquids equally and may experience intermittent regurgitation of food. On the other hand, patients with oesophageal spasm usually experience pain when swallowing.

Oesophageal Cancer: Types, Risk Factors, Features, Diagnosis, and Treatment

Oesophageal cancer used to be mostly squamous cell carcinoma, but adenocarcinoma is now becoming more common, especially in patients with a history of gastro-oesophageal reflux disease (GORD) or Barrett’s. Adenocarcinoma is usually located near the gastroesophageal junction, while squamous cell tumours are found in the upper two-thirds of the oesophagus.

Risk factors for adenocarcinoma include GORD, Barrett’s oesophagus, smoking, achalasia, and obesity. Squamous cell cancer is more common in the developing world and is associated with smoking, alcohol, achalasia, Plummer-Vinson syndrome, and diets rich in nitrosamines.

The most common presenting symptom for both types of oesophageal cancer is dysphagia, followed by anorexia and weight loss. Other possible features include odynophagia, hoarseness, melaena, vomiting, and cough.

Diagnosis is done through upper GI endoscopy with biopsy, endoscopic ultrasound for locoregional staging, CT scanning for initial staging, and FDG-PET CT for detecting occult metastases. Laparoscopy may also be performed to detect occult peritoneal disease.

Operable disease is best managed by surgical resection, with the most common procedure being an Ivor-Lewis type oesophagectomy. However, the biggest surgical challenge is anastomotic leak, which can result in mediastinitis. Adjuvant chemotherapy may also be used in many patients.

Overall, oesophageal cancer is a serious condition that requires prompt diagnosis and treatment. Understanding the types, risk factors, features, diagnosis, and treatment options can help patients and healthcare providers make informed decisions about managing this disease.

Tumor Markers: Understanding Their Role in Cancer Diagnosis and Therapy Control

Tumor markers are substances produced by cancer cells or normal cells in response to cancer. They can be used in the diagnosis and therapy control of various types of cancer. However, it is important to note that tumor markers are non-specific and can also be elevated in non-cancerous conditions.

Prostate-specific antigen (PSA) is a commonly used tumor marker for prostate cancer. It should be offered to those who request testing or for those who have symptoms suggestive of prostate cancer. PSA levels increase with age, so interpretation should take into account the age of the patient. However, PSA levels can also be elevated in benign prostatic enlargement and prostate inflammation, and can be normal in prostate carcinoma.

Alpha-fetoprotein (AFP) is a tumor marker for hepatocellular carcinoma. However, AFP levels can also be normal in this type of cancer. Lactate dehydrogenase (LDH)-1 isoenzyme levels can be elevated in testicular germ cell tumors, while alkaline phosphatase levels can be raised in cholestasis and Paget’s disease.

Carcinoembryonic antigen (CEA) is a tumor marker for colon cancer, but it is non-specific. The introduction of the PSA test has led to earlier diagnosis of prostate cancer, before metastases into lymph nodes or bone are evident. Bone scans are unnecessary in patients with a PSA <20 ng/ml, and repeated scans during treatment are unnecessary in the absence of clinical indications. In summary, tumor markers can be useful in cancer diagnosis and therapy control, but their interpretation should take into account the patient’s age and other non-cancerous conditions that can elevate their levels.

In cases where patients exhibit bradycardia and signs of shock, the recommended initial treatment is administering 500 micrograms of atropine, which can be repeated up to a maximum dose of 3mg. This patient’s ECG findings indicate first-degree heart block, which is consistent with their bradycardia and hypotension. If atropine fails to control the patient’s bradyarrhythmia, other options such as isoprenaline infusions or transcutaneous pacing may be considered. However, intravenous adenosine is not appropriate for this patient as it is used to treat supraventricular tachycardias, which is not the diagnosis in this case. While isoprenaline infusion and transcutaneous pacing are alternative treatments for bradyarrhythmias, they are not the first-line option and should only be considered if atropine is ineffective. Therefore, atropine is the correct answer for this patient’s management.

Management of Bradycardia in Peri-Arrest Rhythms

The 2015 Resuscitation Council (UK) guidelines highlight the importance of identifying adverse signs and potential risk of asystole in the management of bradycardia in peri-arrest rhythms. Adverse signs indicating haemodynamic compromise include shock, syncope, myocardial ischaemia, and heart failure. Atropine (500 mcg IV) is the first line treatment in this situation. If there is an unsatisfactory response, interventions such as atropine (up to a maximum of 3mg), transcutaneous pacing, and isoprenaline/adrenaline infusion titrated to response may be used. Specialist help should be sought for consideration of transvenous pacing if there is no response to the above measures.

Furthermore, the presence of risk factors for asystole such as complete heart block with broad complex QRS, recent asystole, Mobitz type II AV block, and ventricular pause > 3 seconds should be considered. Even if there is a satisfactory response to atropine, specialist help is indicated to consider the need for transvenous pacing. Effective management of bradycardia in peri-arrest rhythms is crucial in preventing further deterioration and improving patient outcomes.

Shingles Vaccine Availability by Age

The shingles vaccine is available to individuals at different ages depending on their stage of life. Those who are 70 or 78-years old are eligible to receive the vaccine. However, it is not routinely offered to patients who are in their 50’s or 60’s. The vaccine is not part of the routine childhood immunisation schedule and is only available to NHS patients in their 70’s. It is not offered to individuals who are 80 or older, as it appears to be less effective in this age group. It is important to consult with a healthcare provider to determine the appropriate age to receive the shingles vaccine.

Hyperreflexia and clonus are commonly observed in patients with severe pre-eclampsia, while a decrease in platelet count may indicate the onset of HELLP syndrome.

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.

Differential Diagnosis of a Woman with Acne and Infertility

Polycystic ovarian syndrome (PCOS), endogenous Cushing’s syndrome, Addison’s disease, congenital adrenal hyperplasia (CAH), and primary hypoparathyroidism are all potential differential diagnoses for a woman presenting with acne and infertility. PCOS is the most likely diagnosis, as it presents with menstrual dysfunction, anovulation, and signs of hyperandrogenism, including excess terminal body hair in a male distribution pattern, acne, and male-pattern hair loss. Endogenous Cushing’s syndrome and primary hypoparathyroidism are less likely, as they do not present with acne and infertility. Addison’s disease is characterized by hyperpigmentation, weakness, fatigue, poor appetite, and weight loss, while CAH may present with oligomenorrhoea, hirsutism, and/or infertility.

Understanding and Managing Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder that affects 10-20% of the population, with women being more likely to develop it than men. It is characterized by abdominal pain, bloating, and altered bowel habits without any specific organic pathology.

Diagnosis of IBS is based on the presence of symptoms such as abdominal pain or discomfort, bloating, and change in bowel habit for at least 6 months. Physical examination and further investigations are necessary to exclude other differential diagnoses.

Management of IBS primarily involves psychological support and dietary measures such as fiber supplementation, low FODMAP diets, increased water intake, and avoiding trigger foods. Pharmacological treatment is adjunctive and should be directed at symptoms. Anti-spasmodics, anti-diarrheals, and antidepressants may have a positive effect on symptoms.

It is important to note that symptoms not consistent with IBS, such as rectal bleeding, anorexia/weight loss, nocturnal symptoms, or fecal incontinence, should alert the clinician to the possibility of an organic pathology. Referral for psychological therapies should be considered for patients who do not respond to pharmacological treatments after 12 months and who develop a continuing symptom profile.
