Takotsubo syndrome, also known as stress-induced cardiomyopathy, is a transient cardiac syndrome that mimics acute coronary syndrome. This condition should be suspected if the patient presents with chest pain after intense emotional stress, accompanied by an abnormal electrocardiogram, elevated levels of myocardial enzymes, and left ventricular apical akinesia on echocardiography. Coronary angiography should be performed for prompt differentiation from ischemic heart disease. A 77-year-old female presented with traumatic multiple fractures of the left sixth and seventh ribs resulting from a violent strike. Clinical findings of physical examination, laboratory tests, electrocardiogram, and coronary angiography provided the diagnosis of Takotsubo syndrome. We performed conservative management including pain control, and the patient was uneventfully discharged seven days after admission.

PURPOSE: To report the ocular health of a community after an accidental release of hydrofluoric acid (HF). METHODS: The hospital records of 327 patients that were exposed to HF between Sep 9, 2012 and Oct 31, 2012 were reviewed. Demographic characteristics, subjective ocular symptoms, and the ophthalmologic examination results of the patients were analyzed retrospectively. RESULTS: Among the 327 patients, 203 patients (62.1%) were exposed to hydrofluoric acid (HF) within 1,000 m of the site of the accident. A total of 131 patients (40.1%) were exposed to HF over 3 days. The most frequently reported ocular symptoms after HF exposure were ocular pain (49.5%) and conjunctival hyperemia (37.9%). Conjunctival hyperemia (43.4%), corneal erosion (23.9%), conjunctiva papilla, and follicles (24.2% and 14.4%, respectively) were noted during ophthalmologic examinations, but 46.2% of patients were normal on examination. None of the patients had vision-threatening damages. CONCLUSIONS: In this study, severe ocular surface changes, which can affect vision, were not identified. This result could be explained by the low atmospheric HF concentration after the accident.

6.Augmentation Index in Connective Tissue Diseases.
Journal of Rheumatic Diseases 2017;24(4):185-191
Atherosclerosis and its complications are often reported in patients with connective tissue diseases (CTDs) showing chronic inflammation. Traditional cardiovascular risk factors do not account for accelerated atherosclerosis in patients with CTDs. Inflammation, although non-traditional, is considered one of the risk factors for endothelial dysfunction, atrial stiffness, and atherosclerosis. Therefore, it is essential to evaluate other risk factors for cardiovascular disease (CVD) in patients with CTDs. The interest in pulse wave analysis (PWA) is growing because of its predictive value for CVD. The arterial pressure waveform is a composite of an incidental wave produced by a ventricular contraction and a reflected wave. The wave reflection can be quantified using the augmentation index (AIx); it is defined as the difference between the inflection and peak systolic pressure, and expressed as a percentage of the pulse pressure. The PWA is represented by AIx. Risk score systems, such as the Framingham scoring system, were correlated with AIx. Many studies have analyzed the ability of the AIx to predict the CAD severity in the general population. In patients with CTDs, the AIx was found to increase compared to a healthy control group. The AIx was related to the activity of CTDs. The treatment for inflammation appeared to improve the AIx in some CTDs. Although more studies will be needed to obtain conclusive evidence, AIx is expected to be a prognostic factor or a risk factor for CVD in patients with CTDs.

There has been a controversy over data of thrombolytic and endovascular surgical treatment about cerebral infarction secondary to infective endocarditis. We report a woman who received early mechanical embolectomy as a treatment of acute stroke with infective endocarditis. A 35-yr-old woman was hospitalized due to right hemiparesis. Brain image showed cerebral infarction at the middle cerebral artery and echocardiography demonstrated vegetation at the mitral valve. She was successfully treated with embolectomy and parenteral antibiotics without any neurologic sequelae. This report shows that the early retrieve of septic cerebral emboli can be a helpful treatment of acute stroke associated with endocarditis.

Postprandial hypotension (PPH) has not been described as a cause of hypotension after the return of spontaneous circulation (ROSC) in the intensive care unit (ICU). A 74 year old man underwent cardiopulmonary resuscitation (CPR) due to monomorphic ventricular tachycardia. After the ROSC, inotropic agents were not reduced but increased. PPH had occurred, according to the flow sheet, so a provocation test was performed. We noted hypotension but no serum hypoglycemia or tachycardia. The hypotension was diagnosed as PPH. We chose acarbose for treatment; thus, the inotropic agents were discontinued. This is the first case in which hypotension occurred in a patient recovering after CPR in the ICU and that the PPH was treated with acarbose. PPH should be considered and treated to manage hypotension in elderly patients in the ICU.

BACKGROUND AND OBJECTIVES: Residual platelet reactivity in patients who are taking clopidogrel is commonly measured with VerifyNow assay, which is based on the principle of light transmission aggregometry. However, to evaluate the residual platelet reactivity, it would be more accurate if the reactivity of platelet glycoprotein (GP) IIb/IIIa is directly monitored. In this study, PAC1, a monoclonal antibody against activated platelet GP IIb/IIIa, was used to measure the residual platelet reactivity. SUBJECTS AND METHODS: Twenty seven patients with coronary artery disease taking clopidogrel were enrolled. Platelets in whole blood were stained with fluorescein isothiocyanate (FITC)-conjugated PAC1. Mean fluorescence intensity (MFI) and % positive platelets (PP) were measured with flow cytometry, and the binding index (BI; MFI x %PP/100) was calculated. P2Y12 reaction unit (PRU) and % inhibition of VerifyNow assay were also measured in the usual manner. RESULTS: PRU of VerifyNow assay correlated significantly with MFI, %PP, and BI at 10 microM (r=0.59, 0.73, and 0.60, respectively, all p<0.005) and 20 microM of adenosine diphosphate (ADP; r=0.61, 0.75, and 0.63, respectively, all p<0.005). The % inhibition also correlated significantly with MFI, %PP, and BI at 10 microM (r=-0.60, -0.69, and -0.59, respectively, all p<0.005) and 20 microM of ADP (r=-0.63, -0.71, and -0.62, respectively, all p<0.005). CONCLUSION: Direct measurements of the reactivity of platelet GP IIb/IIIa were feasible using PAC1 and flow cytometry in patients taking clopidogrel. Further clinical studies are required to determine the cut-off values which would define high residual platelet reactivity in patients on this treatment protocol.
