Sandfly virus seroconversion associated with neurologic presentation.

OBJECTIVE: To describe the clinical presentation and unique neurologic manifestations of sandfly viruses (SFVs) in the Jerusalem area. METHODS: We identified all patients with acute seroconversion to SFV at the Hadassah-Hebrew University Medical Centers during the years 2008-2013 and retrospectively collected and analyzed the clinical and imaging data. RESULTS: Nine patients (ranging from 1.5 to 85 years old) were identified. Presentation included acute neurologic disease, mostly with fever, change in consciousness and behavior, seizures, headache, meningitis, limb paresis, or myelitis. Eight patients had clinical signs of meningitis, meningoencephalitis, or encephalitis alone. Four patients had myelitis. MRI identified pathologic symmetrical changes in the basal ganglia, thalami, and other deep structures in 5 patients, and additional myelitis of the spine was noted on imaging in 3 patients. Seven patients had long-term follow-up: 4 completely recovered and 3 had remaining neurologic sequelae, among them 1 with permanent severe brain damage. CONCLUSION: Neurologic involvement associated with acute SFV infections is considered to be benign. However, in this series, all 9 patients presented with significant neurologic pathology associated with a unique finding of myelitis and symmetrical basal ganglia, thalami, or white matter involvement. Thus, acute SFV infection should be included in the differential diagnosis in febrile onset of neurologic manifestations and neuroradiologic changes.

De novo neonatal antiphospholipid syndrome: a case report and review of the literature.

OBJECTIVES: Neonatal antiphospholipid syndrome (APS) is rare and only few cases have been reported, most of them describing trans-placental passage of penetrable maternal antibodies. The current article aims at defining the clinical and biochemical features of the de novo occurrence of neonatal APS and considerations for long-term treatment. METHODS: We present a case and review the medical literature using PubMed. RESULTS: Including the current report, there are 11 reports of de novo neonatal APS. These include 8 cases of acute ischemic stroke, 2 of venous thrombosis, and 1 of mixed arterial and venous thrombosis. All cases had an additional thrombotic risk factor, either inherited or acquired. Negative maternal history together with low clinical suspicion led to late diagnosis in most cases. In all cases aPL antibodies persisted in the serum throughout the follow-up period. No recurrence of thrombotic events was reported in patients under long-term anticoagulation with either low-molecular-weight heparin (LMWH) or aspirin. There is 1 report of recurrent thrombosis where the patient did not receive anticoagulation. In this case diagnosis was made only retrospectively after recurrence. CONCLUSIONS: We recommend that de novo APS be considered in all cases of unexplained neonatal thrombosis aiming at early diagnosis and implementation of long-term anticoagulation to prevent recurrent thrombotic events.
