Here are the answers to your questions: Q1. Comparative table differentiating chickenpox, measles, and monkeypox | Feature | Chickenpox | Measles | Monkeypox | | :------------------ | :--------------------------------------- | :--------------------------------------- | :--------------------------------------- | | Causative Agent | Varicella-zoster virus (VZV) | Measles virus (Rubeola virus) | Monkeypox virus (Orthopoxvirus) | | Transmission | Airborne (respiratory droplets), direct contact with rash fluid | Airborne (respiratory droplets), direct contact | Direct contact with infected animals/humans (lesions, body fluids, respiratory droplets), contaminated materials | | Clinical Presentation | Itchy rash (macules → papules → vesicles → crusts) appearing in "crops," fever, malaise. | Fever, cough, coryza, conjunctivitis, Koplik spots, maculopapular rash starting on face and spreading downwards. | Fever, headache, muscle aches, lymphadenopathy, rash (macules → papules → vesicles → pustules → scabs) often starting on face/extremities. | | Treatment | Supportive care (antipyretics, antihistamines), antiviral drugs (e.g., acyclovir) for severe cases or high-risk individuals. | Supportive care (antipyretics, hydration, vitamin A supplementation), no specific antiviral treatment. | Supportive care (antipyretics, pain relief, hydration), antiviral drugs (e.g., tecovirimat) for severe cases. | | Prevention | Varicella vaccine | MMR vaccine | Smallpox vaccine (effective against monkeypox), avoiding contact with infected animals, good hygiene. | Q2. A 24-month-old boy with fever and convulsion i) Enumerate five (5) causes of this condition 1. Febrile seizure 2. Meningitis 3. Encephalitis 4. Cerebral malaria 5. Electrolyte imbalance (e.g., hyponatremia) ii) How would you manage this child Step 1: Initial Assessment and Stabilization: Ensure airway patency, breathing, and circulation (ABCs). Place the child in the recovery position. Administer oxygen if needed. Step 2: Stop the Seizure: Administer an anticonvulsant such as rectal diazepam (0.5 mg/kg) or intravenous/intramuscular phenobarbital (15-20 mg/kg loading dose) if the seizure is ongoing or prolonged. Step 3: Fever Management: Administer antipyretics like paracetamol (15 mg/kg orally/rectally) or ibuprofen (10 mg/kg orally) to reduce fever. Remove excess clothing and use tepid sponging. Step 4: Identify and Treat Underlying Cause: Take a detailed history and perform a thorough physical examination. Conduct investigations such as a full blood count, blood glucose, electrolytes, malaria parasite test, and if meningitis is suspected, a lumbar puncture. Treat the specific cause (e.g., antibiotics for bacterial meningitis, antimalarials for malaria). Step 5: Monitoring and Supportive Care: Monitor vital signs, neurological status, and fluid balance. Ensure adequate hydration and nutrition. Provide parental counseling and education on febrile seizures and when to seek urgent medical attention. Q3. Amoebic dysentery a) State the five (5) clinical features of amoebic dysentery 1. Bloody diarrhea (often with mucus) 2. Abdominal pain and cramping 3. Tenesmus (painful straining to pass stool) 4. Fever (less common than in bacterial dysentery, but can occur) 5. Weight loss (in chronic cases) b) How would you manage a 36-month-old child with this condition Step 1: Assessment and Diagnosis: Confirm the diagnosis through stool microscopy to identify Entamoeba histolytica trophozoites or cysts. Assess the child's hydration status and nutritional state. Step 2: Antiamoebic Treatment: Administer a tissue amoebicide such as metronidazole (30-50 mg/kg/day divided into three doses for 5-10 days) to treat invasive disease. Follow with a luminal amoebicide like diloxanide furoate (20 mg/kg/day divided into three doses for 10 days) to eradicate cysts from the gut lumen. Step 3: Fluid and Electrolyte Management: Provide oral rehydration solution (ORS) to prevent or treat dehydration. In severe dehydration, intravenous fluids may be necessary. Step 4: Nutritional Support: Encourage continued feeding with easily digestible, nutritious foods. Address any signs of malnutrition. Step 5: Hygiene and Prevention: Educate parents on proper hand hygiene, safe water sources, and proper food preparation to prevent recurrence and spread. Send me the next one 📸
