RESUMEN
Sheehan's syndrome is defined as a postpartum infarction of the pituitary gland following hypovolemic shock due to obstetric hemorrhage. Sheehan's syndrome's symptoms are often subtle, and hence it is often overlooked. In this report, we discuss a case of an 82-year-old woman who developed severe postpartum hemorrhage after her last childbirth at the age of 37, which required multiple blood transfusions. Since then, she had progressively developed malaise and lastly presented with a new onset of confusion. Basic laboratory tests detected poorly controlled hypothyroidism and severe hyponatremia, which are well-known late-presenting conditions of Sheehan's syndrome. Escaping the diagnosis for more than four decades is extremely rare and beyond what is reported previously. Despite being a rare cause of hyponatremia in the elderly, physicians should maintain a high index of suspicion and are required to look for a readily treatable and preventable cause of hyponatremia (after excluding the common causes), which may alleviate the suffering of these patients.
RESUMEN
BACKGROUND: Baclofen is a centrally acting GABAB receptor agonist and it is used widely for the treatment of spasticity, persistent hiccups and multiple sclerosis. The renal system is the main route of excretion, thus people with suboptimal renal function are prone to baclofen intoxication. Multiple doses of baclofen have been associated with toxicity, but it is very unusual that single dose can do so. CASE PRESENTATION: A 47 year old female patient with end stage renal disease (ESRD) presented with a sudden onset of altered mental status and state of unconsciousness after the ingestion of one tablet of baclofen 25 mg. All other possible causes were ruled out and a diagnosis of baclofen toxicity was considered. The patient showed dramatic improvement after an extra two sessions of hemodialysis. CONCLUSIONS: We highly recommend that more educational efforts are made for health care professionals about the possible risk of baclofen toxicity among kidney-impaired patients. We also recommend avoiding baclofen use if evidence of chronic renal disease is present and to seek other alternatives for pain management.
