🔸1 Define Ischemic heart disease.

Ischemic heart disease (IHD) refers to a group of conditions characterized by reduced blood supply to the heart muscle due to coronary artery disease (CAD). CAD occurs when the coronary arteries, which supply oxygen-rich blood to the heart, become narrowed or blocked by atherosclerosis (plaques composed of cholesterol and other substances).

🔸2 Clinical features and pathophysiology of ischemic heart disease.

Clinical Features of Ischemic Heart Disease:

1. Angina Pectoris: Chest pain or discomfort typically felt during physical exertion or emotional stress. It may radiate to the left arm, jaw, or back.
2. Acute Coronary Syndrome (ACS):

• Unstable Angina: New onset or worsening of chest pain at rest or with minimal exertion.
• Myocardial Infarction (Heart Attack): Sudden onset of severe chest pain that may radiate, often associated with nausea, sweating, shortness of breath, and weakness.

👉Pathophysiology of Ischemic Heart Disease:

1. Atherosclerosis: Formation of plaques in the coronary arteries due to the accumulation of cholesterol, inflammatory cells, and cellular debris.
2. Coronary Artery Spasm: Temporary narrowing of the coronary arteries due to abnormal contraction of the smooth muscle in the artery walls.
3. Thrombosis: Formation of blood clots (thrombi) on the surface of atherosclerotic plaques, leading to sudden blockage of the coronary artery.

🔸3 Write management of a patient with-ischemic heart disease

Management of Ischemic Heart Disease:

1. Lifestyle Modifications:

• Smoking Cessation: Encourage quitting smoking to reduce the risk of further damage to coronary arteries.
• Dietary Changes: Emphasize a heart-healthy diet low in saturated fats, trans fats, and cholesterol.
• Exercise: Encourage regular physical activity to improve cardiovascular health.
• Weight Management: Achieve and maintain a healthy weight to reduce strain on the heart.

2. Pharmacological Therapy:

• Antiplatelet Therapy: Aspirin or other antiplatelet agents to reduce the risk of blood clot formation.
• Statins: Lower LDL cholesterol levels and stabilize plaques in the arteries.
• Beta-Blockers: Reduce heart rate and blood pressure, decreasing oxygen demand on the heart.
• Nitroglycerin: Relieve angina symptoms by dilating coronary arteries and improving blood flow.

3. Invasive Interventions:

• Percutaneous Coronary Intervention (PCI): A procedure to open blocked or narrowed coronary arteries using a balloon catheter and stent placement.
• Coronary Artery Bypass Grafting (CABG): Surgical procedure to reroute blood flow around blocked coronary arteries using grafts from other blood vessels.

4. Monitoring and Rehabilitation:

• Cardiac Rehabilitation: Structured exercise, education, and counseling programs to help patients recover and improve their cardiovascular health.
• Regular Follow-up: Monitor symptoms, medication adherence, and lifestyle modifications.

5. Patient Education and Support:

Hemophilia management has significantly improved with advancements in clotting factor replacement therapies and supportive care, enabling individuals with hemophilia to lead active and fulfilling lives with proper treatment and monitoring. Early diagnosis and comprehensive care are crucial to minimizing complications and improving outcomes.

⏩Q.3 Very Short Answer (Any Four) (4×2-6)

🔸1 Neoplasm

A neoplasm, commonly known as a tumor, refers to an abnormal growth of cells that can be benign (non-cancerous) or malignant (cancerous). Neoplasms arise when cells divide and grow uncontrollably, often forming a mass or lump. They can occur in various tissues or organs throughout the body and are classified based on their behavior and potential to spread. Diagnosis involves imaging tests, biopsies, and histopathological examination. Treatment depends on the type, location, and stage of the neoplasm and may include surgery, radiation therapy, chemotherapy, targeted therapy, or immunotherapy.

🔸2 Chemotherapy

Chemotherapy is a treatment approach for cancer that uses drugs to kill or inhibit the growth of cancer cells. It works by targeting rapidly dividing cells, which includes cancer cells, but can also affect healthy cells that divide quickly (like those in the bone marrow, digestive tract, and hair follicles). Chemotherapy can be administered orally or intravenously and may be used alone or in combination with other treatments such as surgery, radiation therapy, or immunotherapy. The specific drugs and regimen depend on the type and stage of cancer, and treatment aims to shrink tumors, alleviate symptoms, and potentially cure or control the disease.

A cerebrovascular accident, commonly referred to as a stroke, occurs when there is a disruption in the blood supply to the brain, leading to brain tissue damage. This disruption can either be due to a blockage of a blood vessel (ischemic stroke) or the rupture of a blood vessel (hemorrhagic stroke). The pathophysiology and management differ based on the type of stroke:

Pathophysiology:

1.Ischemic Stroke:

• Thrombotic Stroke: Occurs when a blood clot (thrombus) forms in an artery supplying blood to the brain, usually due to atherosclerosis (build-up of fatty deposits on arterial walls).
• Embolic Stroke: Results from a clot (embolus) that forms elsewhere in the body (e.g., heart) and travels through the bloodstream to block a brain artery.

2.Hemorrhagic Stroke:

• Intracerebral Hemorrhage: Occurs when an artery in the brain bursts, causing blood to leak into the brain tissue.
• Subarachnoid Hemorrhage: Involves bleeding into the space between the brain and the thin tissues covering it (subarachnoid space), often due to a ruptured aneurysm.

🔸2 Write management of a patient with CVA

🔸1 Define cirrhosis of liver, Pathophysiology of cirrhosis of liver. 05

Cirrhosis of the Liver:

Cirrhosis of the liver is a chronic and progressive condition where healthy liver tissue is replaced by scar tissue (fibrosis), leading to impaired liver function. It is often a result of long-term liver injury and inflammation caused by various factors such as chronic viral hepatitis, excessive alcohol consumption, non-alcoholic fatty liver disease (NAFLD), autoimmune liver diseases, and certain genetic disorders.

Pathophysiology of Cirrhosis of the Liver:

1. Liver Injury and Inflammation: Initial insult (e.g., chronic viral hepatitis, alcohol abuse) triggers inflammation in the liver.
2. Fibrosis Formation: Chronic inflammation leads to the activation of hepatic stellate cells, which produce collagen and other extracellular matrix components, leading to fibrosis (scar tissue) formation.
3. Nodular Regeneration: As fibrosis progresses, liver tissue undergoes nodular regeneration, causing distortion of liver architecture and impairing blood flow through the liver.
4. Impaired Liver Function: Scar tissue disrupts the liver’s ability to perform essential functions such as detoxification, synthesis of proteins (albumin and clotting factors), and metabolism of nutrients and drugs.
5. Portal Hypertension: Fibrosis and nodular regeneration increase resistance to blood flow through the liver, leading to increased pressure in the portal venous system (portal hypertension).
6. Complications: Portal hypertension can lead to complications such as ascites (fluid accumulation in the abdomen), variceal bleeding (from enlarged veins in the esophagus or stomach), hepatic encephalopathy (brain dysfunction due to liver failure), and hepatorenal syndrome (kidney dysfunction).

Management of a Patient with Cirrhosis of the Liver:

1.Etiological Treatment:

• Identify and treat the underlying cause of cirrhosis (e.g., antiviral therapy for viral hepatitis, alcohol cessation, management of metabolic syndrome).

2.Complication Screening and Prevention:

• Regular screening for complications such as hepatocellular carcinoma (HCC) with imaging studies (ultrasound, CT/MRI) and alpha-fetoprotein (AFP) levels.
• Vaccination against hepatitis A and B, pneumococcus, and influenza to prevent infections.

3.Nutritional Support:

• Ensure adequate nutrition with a balanced diet rich in protein and vitamins, often with the help of a registered dietitian.
• Sodium restriction (typically <2 grams/day) to manage ascites and fluid retention.

4.Management of Portal Hypertension:

• Non-selective Beta-Blockers: Reduce portal pressure and risk of variceal bleeding.
• Endoscopic Variceal Ligation (EVL) or Banding: Prevent variceal bleeding in patients with large varices.
• Transjugular Intrahepatic Portosystemic Shunt (TIPS): Considered for refractory ascites or recurrent variceal bleeding.

5.Ascites Management:

• Sodium Restriction and Diuretics: Initiate therapy with spironolactone and furosemide to reduce ascitic fluid.
• Large-Volume Paracentesis: Remove large amounts of ascitic fluid for symptomatic relief.

6.Hepatic Encephalopathy Management:

• Lactulose: Promote gut flora to produce acids that reduce ammonia absorption.
• Rifaximin: Antibiotic to reduce gut bacteria that produce ammonia.

7.Monitoring and Supportive Care:

• Monitor liver function tests, coagulation profile, and renal function regularly.
• Provide supportive care for complications such as infections, bleeding disorders, and electrolyte imbalances.

8.Liver Transplant Evaluation:

• Refer for liver transplant evaluation in patients with decompensated cirrhosis who meet criteria.

9.Patient Education and Follow-up:

• Educate patients and caregivers about the disease, medications, dietary restrictions, and signs of complications.
• Schedule regular follow-up visits with a hepatologist or gastroenterologist to monitor disease progression and adjust management as needed.

Conclusion:

The management of cirrhosis of the liver requires a multidisciplinary approach aimed at slowing disease progression, managing complications, and improving quality of life. Early intervention and adherence to treatment guidelines are crucial to prevent disease complications and improve long-term outcomes for patients with cirrhosis.

⏩Q.5 Short Essay (Any Three) (3×5-15)

🔸1 Gastritis

Gastritis:

Gastritis refers to inflammation of the lining of the stomach. It can be acute (sudden and short-term) or chronic (long-lasting). Gastritis is commonly caused by irritants such as alcohol, medications, infections, or autoimmune diseases.

Causes of Gastritis:

1. Helicobacter pylori infection: A bacterial infection that commonly causes chronic gastritis.
2. Nonsteroidal anti-inflammatory drugs (NSAIDs): Medications like ibuprofen or aspirin that can irritate the stomach lining.
3. Excessive alcohol consumption: Alcohol can directly irritate the stomach lining and increase stomach acid production.
4. Autoimmune diseases: Conditions where the immune system mistakenly attacks the stomach lining, leading to inflammation (e.g., autoimmune gastritis).
5. Stress: Severe stress from surgery, injury, or critical illness can cause acute gastritis.
6. Bile reflux: Backflow of bile into the stomach due to conditions like bile reflux disease or prior surgery.
7. Other irritants: Smoking, spicy foods, and certain infections (e.g., viral infections) can also contribute to gastritis.

Symptoms of Gastritis:

1. Upper abdominal pain or discomfort: Typically located in the upper middle part of the abdomen.
2. Nausea and vomiting: Especially after eating or drinking alcohol.
3. Indigestion: Feeling of fullness or bloating after meals.
4. Loss of appetite: Decreased desire to eat due to discomfort.
5. Burning or gnawing feeling: Pain may worsen or improve with eating.
6. Vomiting blood or coffee-ground-like material: Indicates bleeding from the stomach lining (a severe symptom requiring immediate medical attention).

Diagnosis of Gastritis:

1. Medical history and physical examination: Discussing symptoms and risk factors with a healthcare provider.
2. Endoscopy: A procedure using a flexible tube with a camera to examine the stomach lining directly and take tissue samples (biopsy).
3. Blood tests: Including tests for H. pylori infection (serology, stool antigen, urea breath test), complete blood count (CBC), and liver function tests.
4. Upper gastrointestinal (GI) series: X-ray imaging after swallowing a contrast material to examine the stomach and small intestine.

Management of Gastritis:

1.Treatment of Underlying Cause:

• H. pylori infection: Antibiotics (such as amoxicillin, clarithromycin, metronidazole) combined with acid-reducing medications (proton pump inhibitors – PPIs).
• NSAIDs: Avoidance or use of alternative medications. PPIs or prostaglandin analogs may be prescribed for those who must continue NSAIDs.
• Alcohol or irritant avoidance: Limiting or eliminating alcohol and other irritants.

2.Medications:

• Proton pump inhibitors (PPIs): Reduce stomach acid production (e.g., omeprazole, pantoprazole).
• Histamine H2-receptor antagonists: Reduce stomach acid production (e.g., ranitidine, famotidine).
• Antacids: Provide quick relief by neutralizing stomach acid (e.g., calcium carbonate, magnesium hydroxide).

3.Lifestyle Modifications:

• Dietary changes: Avoiding spicy, acidic, or irritating foods. Eating smaller, more frequent meals.
• Smoking cessation: Quitting smoking to reduce stomach irritation.
• Stress management: Techniques such as meditation or therapy to reduce stress levels.

6.Follow-up and Referral:

• Schedule follow-up appointments to assess response to treatment and adjust therapy as needed.
• Referral to a gastroenterologist for further evaluation or management of refractory cases or complications.

🔸2 Portal hypertension

Portal Hypertension:

Portal hypertension refers to increased blood pressure within the portal venous system, which carries blood from the digestive organs to the liver. It is typically defined as a hepatic venous pressure gradient (HVPG) greater than 5 mmHg. This condition is often a consequence of liver disease, particularly cirrhosis, but can also result from other conditions affecting the liver or the portal vein itself.

Causes of Portal Hypertension:

1. Cirrhosis: The most common cause, where liver tissue damage and fibrosis (scar tissue) increase resistance to blood flow through the liver.
2. Portal Vein Thrombosis: Blockage or narrowing of the portal vein due to blood clots, leading to increased pressure upstream.
3. Schistosomiasis: A parasitic infection that can cause liver fibrosis and portal hypertension in endemic areas.
4. Budd-Chiari Syndrome: Blockage or narrowing of the hepatic veins, leading to impaired blood flow out of the liver.
5. Congenital Abnormalities: Such as portal vein agenesis or congenital hepatic fibrosis.

Pathophysiology of Portal Hypertension:

1.Increased Resistance to Blood Flow:

• In cirrhosis, fibrosis and nodular regeneration distort liver architecture, compress hepatic sinusoids, and impair blood flow through the liver.
• This leads to increased pressure in the portal vein and its tributaries.

2.Development of Collateral Circulation:

• Portal hypertension causes dilation of collateral vessels (e.g., portosystemic shunts) to bypass the liver and decompress the portal venous system.
• Common collaterals include esophageal varices, gastric varices, and rectal varices.

3.Complications of Portal Hypertension:

• Variceal Bleeding: Dilated veins in the esophagus, stomach, or rectum can rupture, leading to potentially life-threatening bleeding.
• Ascites: Accumulation of fluid in the peritoneal cavity due to increased pressure in the portal vein and decreased albumin production by the liver.
• Hepatic Encephalopathy: Build-up of toxins (especially ammonia) due to impaired liver function and shunting of blood around the liver.
• Hepatorenal Syndrome: Renal dysfunction due to severe circulatory changes and decreased effective arterial blood volume.

Clinical Manifestations of Portal Hypertension:

• Often asymptomatic until complications develop.
• Signs and symptoms may include ascites, jaundice, splenomegaly (enlarged spleen), and collateral vessel formation (e.g., varices).

Diagnosis of Portal Hypertension:

1. Physical Examination: Palpation of an enlarged liver or spleen, presence of ascites, and signs of chronic liver disease.
2. Imaging Studies:

• Ultrasound: To assess liver size, evaluate portal vein patency, and detect ascites.
• CT Scan or MRI: Provides detailed images of liver architecture and identifies portal vein thrombosis or collaterals.

1. Endoscopic Evaluation: Esophagogastroduodenoscopy (EGD) to assess for varices and risk of bleeding.
2. Hepatic Venous Pressure Gradient (HVPG) Measurement: Invasive procedure to directly measure portal pressure and assess risk of variceal bleeding.

Management of Portal Hypertension:

1.Treatment of Underlying Liver Disease:

• Targeted therapy for the underlying cause (e.g., antiviral therapy for hepatitis B or C, alcohol cessation for alcoholic liver disease).

2.Prevention of Complications:

• Variceal Screening and Prophylaxis: Endoscopic variceal ligation (EVL), beta-blockers (e.g., propranolol, nadolol) to reduce portal pressure and risk of bleeding.
• Ascites Management: Sodium restriction, diuretic therapy (e.g., spironolactone, furosemide), paracentesis for symptomatic relief.
• Hepatic Encephalopathy: Lactulose or rifaximin to reduce ammonia levels and manage symptoms.

3.Interventional Procedures:

• Transjugular Intrahepatic Portosystemic Shunt (TIPS): Insertion of a shunt to create a controlled channel between the portal vein and hepatic vein to reduce portal pressure.
• Endoscopic Therapy: Banding or sclerotherapy for variceal bleeding.

4.Surgical Options:

• Liver transplantation for eligible patients with decompensated cirrhosis and refractory complications of portal hypertension.

5.Monitoring and Long-Term Care:

• Regular follow-up to monitor liver function, portal pressure, and assess for complications.
• Patient education regarding signs of bleeding, importance of adherence to medications, and dietary and lifestyle modifications.

🔸3 Shock

Shock:

Shock is a critical medical condition characterized by inadequate tissue perfusion, leading to cellular dysfunction and potentially irreversible organ damage. It is a life-threatening emergency that requires prompt recognition and intervention to restore tissue oxygenation and prevent multi-organ failure.

Types of Shock:

1.Hypovolemic Shock:

• Causes: Severe blood or fluid loss from trauma, surgery, gastrointestinal bleeding, or dehydration.
• Pathophysiology: Decreased intravascular volume leads to reduced cardiac preload, stroke volume, and tissue perfusion.
• Clinical Features: Hypotension, tachycardia, cool and clammy skin, decreased urine output.

2.Cardiogenic Shock:

• Causes: Acute myocardial infarction (heart attack), severe arrhythmias, myocarditis, or cardiomyopathy.
• Pathophysiology: Impaired cardiac function decreases cardiac output and systemic perfusion despite adequate intravascular volume.
• Clinical Features: Hypotension, signs of congestive heart failure (e.g., pulmonary edema), cool extremities.

3.Distributive Shock:

• Types:
  • Septic Shock: Caused by overwhelming infection leading to systemic inflammation and vasodilation.
  • Anaphylactic Shock: Severe allergic reaction causing widespread vasodilation and increased vascular permeability.
  • Neurogenic Shock: Loss of sympathetic tone due to spinal cord injury or severe central nervous system disorders.
• Pathophysiology: Vasodilation and maldistribution of blood volume reduce effective circulating volume and tissue perfusion.
• Clinical Features: Hypotension, warm and flushed skin (in septic and anaphylactic shock), bradycardia (in neurogenic shock).

4.Obstructive Shock:

• Causes: Mechanical obstruction of blood flow due to conditions like pulmonary embolism, tension pneumothorax, or cardiac tamponade.
• Pathophysiology: Impaired cardiac filling and decreased cardiac output despite normal myocardial function.
• Clinical Features: Hypotension, signs specific to the underlying cause (e.g., absent breath sounds in tension pneumothorax, Beck’s triad in cardiac tamponade).

General Principles of Shock Management:

1.Early Recognition and Assessment:

• Identify signs and symptoms of shock including hypotension, altered mental status, tachycardia, and cool/clammy skin.
• Perform a focused physical examination to determine the type and severity of shock.

2.Supportive Measures:

• Oxygen Therapy: Provide supplemental oxygen to maintain adequate tissue oxygenation.
• Intravenous Access: Establish large-bore peripheral or central venous access for fluid resuscitation and medication administration.

3.Fluid Resuscitation:

• Crystalloids: Initial fluid of choice (e.g., normal saline, lactated Ringer’s) to restore intravascular volume.
• Colloids: Consider in cases of severe hypovolemia or inadequate response to crystalloids (e.g., albumin, synthetic colloids).

4.Vasoactive Medications:

• Inotropes and Vasopressors: Initiate if fluid resuscitation alone does not restore adequate blood pressure and perfusion (e.g., norepinephrine, dopamine).
• Administer according to hemodynamic monitoring parameters to optimize cardiac output and vascular tone.

5.Treat Underlying Cause:

• Address the specific cause of shock (e.g., antibiotics for septic shock, pericardiocentesis for cardiac tamponade, surgery for obstructive shock).

6.Monitoring and Reassessment:

• Continuously monitor vital signs, urine output, central venous pressure (CVP), and/or arterial pressure (invasive monitoring) to guide treatment and assess response.
• Reevaluate response to treatment and adjust management accordingly.

7.Supportive Care:

• Provide comprehensive care including pain management, infection control, and nutritional support.
• Consider early involvement of critical care specialists or multidisciplinary teams for complex cases or refractory shock.

8.Complications Prevention:

• Prevent complications such as acute respiratory distress syndrome (ARDS), acute kidney injury (AKI), and disseminated intravascular coagulation (DIC) through vigilant monitoring and proactive management.

9.Post-Shock Care and Rehabilitation:

• Initiate rehabilitation early to optimize recovery of organ function and minimize long-term sequelae.
• Plan for appropriate discharge and follow-up care to address ongoing needs and prevent recurrence.

🔸4 Hernia

Hernia:

A hernia occurs when an organ or fatty tissue protrudes through a weak spot or tear in the surrounding muscle or connective tissue, forming a bulge. Hernias can develop in various parts of the body, but they most commonly occur in the abdomen.

Types of Hernias:

1.Inguinal Hernia:

• Description: Occurs in the groin where the abdominal wall weakens, allowing intestines or abdominal tissue to protrude into the inguinal canal.
• Risk Factors: Male gender, older age, chronic cough, heavy lifting, and family history.
• Symptoms: Visible bulge in the groin area that may become more prominent with straining, discomfort, and pain, especially when bending over or lifting.

2.Femoral Hernia:

• Description: Less common than inguinal hernias, femoral hernias occur when abdominal contents protrude through the femoral canal, below the inguinal ligament.
• Risk Factors: More common in females, obesity, pregnancy, and previous groin surgery.
• Symptoms: Often presents as a painful lump in the groin area, more common in women than men.

3.Incisional Hernia:

• Description: Develops at the site of a previous surgical incision where the abdominal wall has weakened or split open.
• Risk Factors: Previous abdominal surgery, obesity, poor wound healing, and increased intra-abdominal pressure.
• Symptoms: Visible bulge or swelling at the site of the surgical scar, often exacerbated by activities that increase intra-abdominal pressure.

4.Umbilical Hernia:

• Description: Occurs around the belly button (umbilicus) where the abdominal wall muscles have not fully closed during fetal development or have weakened later in life.
• Risk Factors: Infants (congenital umbilical hernias), obesity, multiple pregnancies, and chronic cough.
• Symptoms: Bulge or protrusion near the belly button that may be painless or tender, especially when straining.

5.Hiatal Hernia:

• Description: Develops when part of the stomach protrudes up through the diaphragm into the chest cavity, commonly associated with the hiatus (opening in the diaphragm).
• Risk Factors: Age-related weakening of the diaphragm, obesity, and frequent heavy lifting.
• Symptoms: Often asymptomatic but may cause heartburn, acid reflux, difficulty swallowing, and chest pain.

6.Pathophysiology:

• Hernias occur due to weakened muscles or connective tissue in the abdominal wall, allowing intra-abdominal contents to push through.
• Increased intra-abdominal pressure from factors like lifting heavy objects, straining during bowel movements, chronic cough, or obesity can exacerbate hernia formation.

7.Clinical Presentation:

• Visible bulge or swelling at the hernia site.
• Pain or discomfort, especially with lifting, coughing, or straining.
• Nausea, vomiting, or difficulty with bowel movements (in strangulated hernias).

8.Diagnosis:

• Physical examination by a healthcare provider to assess for a palpable bulge or swelling.
• Imaging studies such as ultrasound or CT scan may be used to confirm the diagnosis and assess the size and contents of the hernia.

9.Management:

1. Watchful Waiting: Small, asymptomatic hernias may not require immediate treatment but should be monitored regularly.
2. Non-surgical Treatment:

• Hernia Truss: A supportive device worn over the hernia to provide temporary relief from symptoms, not recommended for long-term use.
• Lifestyle Modifications: Weight loss, smoking cessation, avoiding heavy lifting, and treating underlying conditions that increase intra-abdominal pressure.

10.Surgical Repair:

• Indications: Persistent symptoms, risk of complications (e.g., incarceration, strangulation), or cosmetic concerns.
• Types of Surgery: Open repair (traditional), laparoscopic (minimally invasive), or robotic-assisted surgery.
• Techniques: Mesh placement to reinforce the weakened abdominal wall and reduce recurrence rates.

11.Postoperative Care:

• Pain management, wound care, and gradual return to normal activities as advised by the surgeon.
• Follow-up appointments to monitor healing, assess for recurrence, and address any complications.

12.Complications:

• Incarceration: Hernia contents become trapped and cannot be pushed back into the abdomen.
• Strangulation: Blood supply to hernia contents is compromised, leading to tissue ischemia and potentially necrosis.
• Recurrence: Return of the hernia after surgical repair, more common in large hernias or with inadequate surgical technique.

⏩Q.6 Very Short Answer (Compulsory) (6×2-12)

🔸1 Prolapsed disc

A prolapsed disc, often referred to as a herniated disc, occurs when the soft cushion-like material (disc) between the vertebrae in the spine bulges or ruptures. This can cause pain, numbness, or weakness, typically in the area where the affected nerves are located. Treatment options range from rest and pain management to physical therapy and, in severe cases, surgery.

🔸2 Arthritis

Arthritis refers to inflammation of the joints, causing pain, stiffness, swelling, and decreased range of motion. There are several types, including osteoarthritis (caused by wear and tear on joints), rheumatoid arthritis (an autoimmune disorder), and others. Treatment focuses on managing symptoms through medication, physical therapy, lifestyle changes, and sometimes surgery, depending on the severity and type of arthritis.

🔸3 Endocarditis

Endocarditis is an infection of the inner lining of the heart chambers and valves (endocardium). It often occurs when bacteria or other germs from elsewhere in the body spread through the bloodstream and attach to damaged areas of the heart. Symptoms may include fever, chills, fatigue, and sometimes heart murmur. Treatment involves antibiotics and, in severe cases, surgical repair of damaged heart valves. Early diagnosis and treatment are crucial to prevent complications.

🔸4 Lung Abscess

A lung abscess is a localized collection of pus within the lung tissue, typically caused by bacterial infection. It often develops after aspiration of food, liquid, or vomit into the lungs, or due to pneumonia that doesn’t improve with treatment. Symptoms include persistent cough, fever, chest pain, and sometimes coughing up blood. Treatment involves antibiotics to clear the infection and sometimes drainage of the abscess through a procedure or surgery, depending on its size and severity. Early detection and prompt treatment are important to prevent complications.

🔸5 Pancreatitis

Pancreatitis is inflammation of the pancreas, a gland behind the stomach that produces digestive enzymes and hormones like insulin. It can be acute (sudden and short-term) or chronic (long-lasting). Causes include gallstones, alcohol abuse, certain medications, infections, or genetic factors. Symptoms include severe abdominal pain, nausea, vomiting, and fever. Treatment focuses on pain management, fluid replacement, and addressing the underlying cause. Severe cases may require hospitalization and supportive care, including possible surgery to remove damaged tissue or manage complications.

🔸6 Fissures

An anal fissure is a small tear or cut in the lining of the anus, which can cause pain, bleeding during bowel movements, and itching. It typically occurs due to trauma from passing hard or large stools, chronic diarrhea, or conditions like Crohn’s disease. Treatment usually involves dietary changes to soften stools, topical medications to reduce pain and promote healing, and occasionally, surgical procedures if conservative measures don’t resolve the fissure. Prompt treatment can help alleviate symptoms and prevent complications.
