ABSTRACT

Congenital factor VII deficiency is a challenging disorder to manage, as it is associated with varied genotypes that do not clinically correlate with a bleeding phenotype. Individuals with severe factor VII deficiency (FVII: c <1%) might be asymptomatic, while patients with moderate deficiency (FVII: c level >5%) may experience severe hemorrhages. In modern medicine, due to extensive routine pre-operative laboratory testing, clinically asymptomatic patients without any bleeding history might be incidentally discovered, raising clinical dilemmas. Careful consideration of bleeding versus thrombosis risk has to be made in such cases, especially in the elderly. Clinical history of no prior bleeding complications may be a reassuring factor. Minimal required replacement dosing of recombinant activated factor VII can be given peri-operatively in such situations, with close monitoring.
Keywords: Factor VII deficiency, Factor VII replacement, bleeding.

ABSTRACT

Myxedema coma, a rare entity in 21st century in developed nations, is a decompensated phase of hypothyroidism with high mortality rates. We describe a young woman with myxedema, who developed respiratory failure, congestive heart failure and significant pericardial effusion, some of the uncommon manifestations. Decreased cardiac contractility can result in cardiomyopathy and heart failure. As illustrated by this case, myxedema can also result in significant pericardial effusion due to increased vascular permeability. Myxedema can further be complicated by alveolar hypoventilation and respiratory failure secondary to the lack of central drive as well as respiratory muscle weakness. Prompt therapy with thyroid hormone replacement, glucocorticoid therapy, aggressive supportive care and management of the precipitating event can save lives and reverse the cardiopulmonary symptoms, as in our patient. Hence, physicians should have a high index of suspicion for myxedema coma in patients with unexplained cardiopulmonary failure. Our report is, therefore, aimed at bringing awareness about the rare but fatal manifestations of myxedema coma.
