Fulminant Lymphocytic Myocarditis Successfully Managed with Intra-Aortic Balloon Pump and Extracorporeal Membrane Oxygenation: A Case Report.

BACKGROUND Lymphocytic myocarditis (LM) is a rare inflammatory disease of the heart. The clinical presentation of LM varies from mild flu-like symptoms to fulminant myocarditis with cardiogenic shock. Fulminant myocarditis has a poor prognosis and the usual treatment is inotropes with or without ventricular assist devices such as intra-aortic balloon pump (IABP) and venoarterial extracorporeal membrane oxygenation (V-A ECMO). We report the case of fulminant LM with severe cardiogenic shock that was successfully treated with concomitant use of IABP and V-A ECMO. CASE REPORT A 32-year-old woman with no medical history presented to the Emergency Department (ED) with chest pain with irradiation to the left upper limb, worse when supine. The electrocardiogram (ECG) on admission showed sinus rhythm with nonspecific ST-T repolarization abnormalities, and laboratory results showed elevated ultrasensitive troponin and C-reactive protein. Transthoracic echocardiography (TTE) showed left ventricular ejection fraction (LVEF) of 25% and diffuse hypokinesis. On the next day, she developed cardiogenic shock requiring vasoactive drugs, IABP, and V-A ECMO. Pulse therapy with methylprednisolone was started. Endomyocardial biopsy (EMB) revealed acute LM, and intravenous human immunoglobulin was administered. The patient evolved with progressive clinical improvement, being discharged 56 days after admission, with an improvement in the LVEF to 55%. CONCLUSIONS Fulminant LM is a rare and potentially fatal condition that requires immediate intervention. The combination of IABP and V-A ECMO among patients with LM-cardiogenic shock may provide survival benefits.

Evaluation of Postoperative Deficits following Motor Cortex Tumor Resection using Small Craniotomy.

Introduction Surgical treatment of brain tumors in eloquent areas has always been considered a major challenge because removal-related cortical damage can cause serious functional impairment. However, few studies have investigated the association between small craniotomies and the higher risk of incidence of motor deficits and prolonged recovery time. Here, we analyzed neurologic deficits and the prognostic variables after surgery guided by navigation for motor cortex tumors under general anesthesia. Methods This was a prospective study that included 47 patients with tumors in the precentral gyrus. All surgeries were performed with neuronavigation and cortical mapping, with direct electrical stimulation of the motor cortex. We evaluated the prognostic evolution of patients with pre- and postoperative Karnofsky Performance Scale using the Eastern Cooperative Oncology Group scale. Results Complete resection was verified in all 18 cases of metastasis, 13 patients with glioblastoma multiforme, and 5 patients with low-grade gliomas. An analysis of the motor deficits revealed that 11 patients experienced worsening of the deficit on the first day after surgery. Only four patients developed new deficits in the immediate postoperative period, and these improved after 3 weeks. After 3 months, only two patients had deficits that were worse those experienced prior to surgery; both patients had glioblastoma multiforme. Conclusion In our series, motor deficits prior to surgery were the most important factors associated with persistent postoperative deficits. Small craniotomy with navigation associated with intraoperative brain mapping allowed a safe resection and motor preservation in patients with motor cortex brain tumor.
