A 54 years old previously well patient admitted with progressively worsening shortness of breath for 2 days duration. He had low grade fever for the same duration. There was no history of cough, wheezing or chest pain. He had facial and leg swelling. 4 days back he had taken medications from the local hospital for a back pain he developed after lifting a cupboard. What are the differential diagnoses? Like in any patient with acute SOB, respiratory and cardiac causes should be considered first. On examination he was ill, tachypnoeic and had generalized edema. There was a erythematous rash all over the body. Blood pressure was 180/100mmHg. There was no cardiomegaly or murmurs. Lungs had few basal crepirations and occasional wheezing. Abdomen was soft. In patients who are tachypnoeic, few lung signs can always be present. Correlate the degree of SOB with the lung signs. If the SOB is disproportionately severe compared to the signs, consider following differentials. Pulm

Things not to miss - Acute MI

A 54 years old male patient, known to have GORD for many years presented with burning chest pain. The pain was persistent. There was no radiation to the arm. He had sweating and nausea. There was no shortness of breath. He is a smoker. He has never tested his blood sugar or lipid profile. On examination, the patient is ill and sweaty. The pulse rate is 92/min. Blood pressure is 150/100mmHg. There are no murmurs. Lungs are clear. What are you going to do? This is a very common clinical scenario. Nearly half of the patients you encounter will admit that they have ’Gastritis’. The majority who present with chest pain believe that the pain is due to gastritis. So the clinical problem is differentiating ischemic chest pain from gastritis. What features will suggest that the pain is ischemic? You know what the features are. I’ll highlight only a few points. In most MIs the pain is tightening. But we have seen patients with burning pain coming with MI. So

Treatment of thyrotoxicosis has several aspects 1. Symptomatic relief Beta-blockers are the first line. Beta-blockers can be started even before the diagnosis is confirmed. When you suspect thyrotoxicosis start beta-blockers before reviewing the patient with TSH and Free T4 reports. The usual dose is Propranolol 20-40mg three to four times a day. Make sure the patient does not have bronchial asthma! 2. Reduce thyroid hormone synthesis Thionamides are safe and have a quick onset of action Carbimazole is the commonly used drug The usual dose is 10mg three times a day, but according to the initial Free T4 level, the dose can be adjusted. The maintenance dose should be continued for a year or two before considering stopping the treatment. Many patients will relapse requiring other definitive treatments MCQ tip Agranulocytosis is a 'favorite' complication of thionamides The patient should be advised to stop taking carbimazole and immediately come to the hos
