Background: This meta-analysis aims to evaluate the utility of speckle tracking echocardiography (STE) as a tool to evaluate for cardiac sarcoidosis (CS) early in its course. Electrocardiography and echocardiography have limited sensitivity in this role, while advanced imaging modalities such as cardiac magnetic resonance (CMR) and 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) are limited by cost and availability. Methods: We compiled English language articles that reported left ventricular global longitudinal strain (LVGLS) or global circumferential strain (GCS) in patients with confirmed extra-cardiac sarcoidosis versus healthy controls. Studies that exclusively included patients with probable or definite CS were excluded. Continuous data were pooled as a standard mean difference (SMD), comparing sarcoidosis group with healthy controls. A random-effect model was adopted in all analyses. Heterogeneity was assessed using Q and I2 statistics. Results: Nine studies were included in our final analysis with an aggregate of 967 patients. LVGLS was significantly lower in the extra-cardiac sarcoidosis group as compared with controls, SMD −3.98, 95% confidence interval (CI): −5.32, −2.64, P < .001, also was significantly lower in patients who suffered major cardiac events (MCE), −3.89, 95% CI −6.14, −1.64, P < .001. GCS was significantly lower in the extra-cardiac sarcoidosis group as compared with controls, SMD: −3.33, 95% CI −4.71, −1.95, P < .001. Conclusion: LVGLS and GCS were significantly lower in extra-cardiac sarcoidosis patients despite not exhibiting any cardiac symptoms. LVGLS correlates with MCEs in CS. Further studies are required to investigate the role of STE in the early screening of CS.

A 24-year-old man complained of a right temporal headache for four weeks. The patient denied any trauma or previous anticoagulation use. He also reported tender right facial swelling. His physical exam was unrevealing except for right cranial nerve (CN) VI palsy, right parotid enlargement, and cervical adenopathy. Laboratory findings were significant for mild leukopenia at 3300 cells/uL. The computed tomography (CT) scan obtained showed a chronic left subdural effusion with a 4 mm midline shift and confirmed right parotid enlargement and cervical lymphadenopathy. Surgical burr hole evacuation was done and the fluid was sent for wound culture analysis. The infectious diseases service recommended initiating antibiotics, which were later stopped due to cerebrospinal fluid (CSF) cultures with no growth of any organisms. His CN VI palsy resolved during admission. The patient was discharged with follow-up for biopsy. The patient was lost to follow-up. The patient presented to the emergency department (ED) three months later, with a left-sided frontal headache. A repeat CT scan showed a new, right-sided fluid collection outside the brain parenchyma. Burr hole evacuation was done again and purulent fluid was drained. Antibiotics were held this time, but anti-tuberculous therapy was initiated empirically. The otolaryngology service was consulted and a lymph node biopsy was performed. The pathology showed histiocytic necrotizing lymphadenitis. A dural biopsy was done as well and was consistent with histiocytic necrotizing lymphadenitis involving the dura. Cultures from the subdural fluid did not grow any organism. The patient remained neurologically intact. He improved after surgery was done to drain the fluid and was managed by analgesics. The cultures from the extra-parenchymal fluid collection remained negative for pathogens and tuberculous mycobacteria. The patient was discharged with rheumatology clinic follow-up. He saw the rheumatologist six weeks after the discharge. During his clinic visit, the patient reported no recurrence of headaches, fevers, rash, or joint pain. Our patient had a rare presentation of Kikuchi-Fujimoto disease, in which he had a subdural fluid collection resulting in neurological complications that required surgical intervention.

Background Myocardial infarction in nonobstructive coronary artery disease (MINOCA) is a recently described infarct subtype. There are few studies that examine coronary artery disease (CAD) extent, MI size and type, and treatment differences at hospital discharge compared to myocardial infarction in obstructive coronary artery disease (MICAD), or that explore sex-specific MINOCA attributes of coronary anatomy and infarct size. Methods Our study population consisted of a single tertiary-center of consecutive patients that had coronary angiography for acute MI between 2005 and 2015. The MI type at presentation, MI size and ejection fraction (post-MI), and gender differences between MINOCA patients were examined. Result Among 1698 cases with acute MI, 95 had MINOCA (5.6%). MINOCA patients were younger, more often had NSTEMI, lower peak cardiac troponin (cTn) values, and greater ejection fraction than MICAD patients (all P-values <0.005). At hospital discharge, 30-day re-admission rates were similar. MINOCA patients less frequently received optimal medical therapy. When women were analyzed, the 45 women with MINOCA had smaller MIs (P < 0.001) and greater ejection fraction (P = 0.002) than the 358 women with MICAD. Sex comparisons of the 95 MINOCA patients revealed women were older than men (P < 0.001), had lower mean peak cTn values (P < 0.001), greater ejection fraction (P = 0.02), and more single-vessel disease involvement than men (P < 0.0001). Conclusion The average MI size is smaller in MINOCA than MICAD patients, and there are sex-related differences in clinical presentation, coronary artery disease extent, and MI size. Re-admission rates are similar and MINOCA patients are less likely to receive guideline recommended medical therapy at discharge.
