Acute Lyme Neuroborreliosis With Transient Hemiparesis and Aphasia.

Nervous system involvement in Lyme disease often mimics other conditions and thus represents a diagnostic challenge, especially in an emergency department setting. We report a case of a female teenager presenting with sudden-onset aphasia and transient right-sided faciobrachial hemiplegia, along with headache and agitation. Ischemia, vasculitis, or another structural lesion was excluded by brain imaging. Toxicologic evaluation results were negative. Cerebral perfusion computed tomography and electroencephalography showed left parietotemporal brain dysfunction. Lumbar puncture result, although atypical, suggested bacterial infection and intravenous ceftriaxone was initiated. Finally, microbiological cerebrospinal fluid analysis revealed Lyme neuroborreliosis, showing specific intrathecal antibody production and high level of C-X-C motif chemokine 13. The patient rapidly recovered. To our knowledge, this report for the first time illustrates that acute-onset language and motor symptoms may be directly related to Lyme neuroborreliosis. Neuroborreliosis may mimic other acute neurologic events such as stroke and should be taken into diagnostic consideration even in the absence of classic symptoms and evolution.

Outcome of patients admitted with acute coronary syndrome on palliative treatment: insights from the nationwide AMIS Plus Registry 1997-2014.

OBJECTIVE: Compliance with guidelines is increasingly used to benchmark the quality of hospital care, however, very little is known on patients admitted with acute coronary syndromes (ACS) and treated palliatively. This study aimed to evaluate the baseline characteristics and outcomes of these patients. DESIGN: Prospective cohort study. SETTING: Eighty-two Swiss hospitals enrolled patients from 1997 to 2014. PARTICIPANTS: All patients with ACS enrolled in the AMIS Plus registry (n=45,091) were analysed according to three treatment groups: palliative treatment, defined as use of aspirin and analgesics only and no reperfusion; conservative treatment, defined as any treatment including antithrombotics or anticoagulants, heparins, P2Y12 inhibitors, GPIIb/IIIa but no pharmacological or mechanical reperfusion; and reperfusion treatment (thrombolysis and/or percutaneous coronary intervention during initial hospitalisation). The primary outcome measure was in-hospital mortality and the secondary measure was 1-year mortality. RESULTS: Of the patients, 1485 (3.3%) were palliatively treated, 11,119 (24.7%) were conservatively treated and 32,487 (72.0%) underwent reperfusion therapy. In 1997, 6% of all patients were treated palliatively and this continuously decreased to 2% in 2013. Baseline characteristics of palliative patients differed in comparison with conservatively treated and reperfusion patients in age, gender and comorbidities (all p<0.001). These patients had more in-hospital complications such as postadmission onset of cardiogenic shock (15.6% vs 5.2%; p<0.001), stroke (1.8% vs 0.8%; p=0.001) and a higher in-hospital mortality (25.8% vs 5.6%; p<0.001).The subgroup of patients followed 1 year after discharge (n=8316) had a higher rate of reinfarction (9.2% vs 3.4%; p=0.003) and mortality (14.0% vs 3.5%; p<0.001). CONCLUSIONS: Patients with ACS treated palliatively were older, sicker, with more heart failure at admission and very high in-hospital mortality. While refraining from more active therapy may often constitute the most humane and appropriate approach, we think it is important to also evaluate these patients and include them in registries and outcome evaluations.

CTP in Transient Global Amnesia: A Single-Center Experience of 30 Patients.

BACKGROUND AND PURPOSE: Medial temporal lobe abnormalities on DWI and functional imaging are occasionally observed in patients with transient global amnesia. We used CTP to study these patients during or briefly after resolution of their amnesic syndrome. MATERIALS AND METHODS: From 2002 onward, patients satisfying clinical criteria for transient global amnesia who underwent CTP were included. Patients with additional clinical features suggesting transient ischemic attack or stroke and those with an ischemic lesion on subsequent DWI were excluded. If deemed necessary by the clinician, DWI was performed within 10 days. RESULTS: Thirty patients with transient global amnesia underwent CTP at a median latency of 5.9 hours (interquartile range, 4.3-9.7 hours) after symptom onset. All findings, except for those in 1 patient, were normal, including those in the 14 patients with well-imaged hippocampi. In the patient with abnormal findings, CTP and PWI showed hypoperfusion in both lentiform nuclei extending into the insulae, with normalization on the repeat CTP 6 days later. In 10 patients, DWI was performed at a median latency of 2 days (interquartile range, 0-9 days). Of these, 2 showed punctate hippocampal lesions, often seen in transient global amnesia. In 2 patients excluded because of mildly atypical transient global amnesia and ischemic lesions on subsequent DWI, acute CTP findings were also normal. CONCLUSIONS: Patients with transient global amnesia had normal CTP findings in the acute phase with the exception of 1 patient with transient hypoperfusion in both basal ganglia. If imaging is performed for typical and atypical transient global amnesia, DWI should be the preferred method.
