Abstract:
We report the case of a 65-year-old woman presenting with recurrent vomiting for 3 days. She had been previously diagnosed with an atrial septal defect and was on treatment with diuretics and digoxin for paroxysmal supraventricular tachycardia. The clinical examination was consistent with an atrial septal defect with severe pulmonary hypertension. Electrocardiography showed complete heart block with ST-segment changes suggestive of digitalis toxicity. Transthoracic echocardiography confirmed Eisenmengerisation. Serum digoxin levels were elevated. Following hospitalisation, she was diagnosed with photophobia when she persistently asked for ambient lighting to be switched off. Most interestingly, the patient kept reporting seeing little yellow men, which was how she perceived the attending doctors. Cessation of digoxin therapy led to progressive abatement of her symptoms.
Insights
Digitalis toxicity from digoxin can cause visual disturbances, including seeing yellow figures, and photophobia. Discontinuing digoxin resolved these symptoms in a patient with atrial septal defect.
Area of Science:
- Cardiology
- Clinical Toxicology
Background:
- A 65-year-old woman with atrial septal defect and paroxysmal supraventricular tachycardia was treated with digoxin and diuretics.
- She presented with recurrent vomiting, severe pulmonary hypertension, and complete heart block.
Observation:
- Clinical examination and transthoracic echocardiography confirmed an atrial septal defect with Eisenmengerization.
- Electrocardiography revealed ST-segment changes indicative of digitalis toxicity.
- The patient developed photophobia and visual hallucinations, describing doctors as 'little yellow men'.
Findings:
- Serum digoxin levels were significantly elevated.
- Cessation of digoxin therapy resulted in the gradual resolution of her symptoms, including visual disturbances and photophobia.
Implications:
- This case highlights the importance of considering digitalis toxicity in patients with elevated digoxin levels presenting with neurological and visual symptoms.
- It underscores the need for careful monitoring of digoxin levels and potential toxicity in patients with underlying cardiac conditions.
- Recognizing these specific visual disturbances can aid in the early diagnosis and management of digoxin toxicity.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
