Takotsubo cardiomyopathy in aneurysmal subarachnoid hemorrhage: Institutional experience and literature review

Objectives: To review the current practice in the diagnosis, monitoring and management of TCM in SAH patients at our tertiary referral institution and the relevant literature, and to evaluate the effect of certain treatment modalities on the outcome of those patients. Patients and methods: A retrospective institutional chart review of 800 patients with aneurysmal SAH from 2007 to 2014. Eighteen patients were identified to have both aneurysmal SAH and TCM based on echocardiogram. Demographic data, clinical parameters, radiographic findings, treatment modalities, and laboratory results were analyzed. Results: The incidence of typical TCM in our patients was 2.2%. Mortality rate of TCM in SAH was 22% compared to the total mortality rate of all non-traumatic SAH patients of 15% in our institution over the same time period. Use of beta blockers prior to or after the diagnosis of TCM did not seem to affect their outcome. Majority of patients (61%) were on vasopressors prior to the diagnosis of TCM. Of those, 73% had good outcomes. Even after the diagnosis of TCM, good outcomes were observed in 6 of 7 patients who remained on vasopressors. Conclusion: Despite the general agreement on the importance of the avoidance of vasopressors in TCM, our experience showed that the use of vasopressors is safe in these patients. The use of beta blockers in our patients was not associated with significantly better outcomes despite multiple previous reports on beta blocker usage in TCM. (C) 2015 Elsevier B.V.

Subacute Thyroiditis: Clinical Presentation and Long Term Outcome

Few studies have been reported from the Kingdom of Saudi Arabia (SA) to describe the clinical presentation and long term outcomes of subacute thyroiditis (SAT). Our aim was to review the demographic, anthropometric, clinical presentation, laboratory results, treatment, and disease outcome in Riyadh region and to compare those with results from different regions of the Kingdom and different parts of the world. We reviewed the medical files of patients who underwent thyroid uptake scan during an 8-year period in King Khalid University Hospital. Only 25 patients had confirmed diagnosis of thyroiditis. Age and gender distribution were similar to other studies. Most patients presented with palpitation, goiter, and weight change. Elevated thyroid hormones, suppressed thyroid-stimulating hormone, and elevated ESR were reported. Among those, 7 cases of SAT were recorded. β-Blockers were prescribed to 57% and nonsteroidal anti-inflammatory drugs to 29% of SAT. Long follow-up demonstrated that 85.7% of SAT cases recovered, while 14.3% developed permanent hypothyroidism. In conclusion, SAT is uncommon in the central region of SA. Compared to the western region, corticosteroid is not commonly prescribed, and permanent hypothyroidism is not uncommon. A nation-wide epidemiological study to explain these interprovincial differences is warranted
