Livedoid vasculopathy is a rare cutaneous disease manifesting as recurrent ulcers on the lower extremities. The ulceration results in atrophic, porcelain white scars termed as atrophie blanche. The pathogenesis is yet to be understood with the main mechanism being hypercoagulability and inflammation playing a secondary role. The important procoagulant factors include protein C and S deficiency, factor V Leiden mutation, antithrombin III deficiency, prothrombin gene mutation and hyperhomocysteinemia. Histopathology of livedoid vasculopathy is characterized by intraluminal thrombosis, proliferation of the endothelium and segmental hyalinization of dermal vessels. The treatment is multipronged with anti-thrombotic measures such as anti-platelet drugs, systemic anticoagulants and fibrinolytic therapy taking precedence over anti-inflammatory agents. Colchicine, hydroxychloroquine, vasodilators, intravenous immunoglobulin, folic acid, immunosuppressive therapy and supportive measures are also of some benefit. A multidisciplinary approach would go a long way in the management of these patients resulting in relief from pain and physical as well as psychological scarring.

Introduction:Dengue, an acute viral disease transmitted by Aedes mosquitoes, is highly endemic in many tropical and subtropical areas of the world. Neurological complications of dengue infection have been observed more frequently in the recent past and some studies highlighted varied neurological complications arising in the course of dengue illness. In this retrospective study, we report various neurological complications observed during the last 2 years in patients of dengue fever.Materials and Methods:The patients presenting with neurological complications with positive serology (IgM antibody) for dengue infection were consecutively recruited from the Department of Neurology/Medicine from a tertiary center of Lucknow, India. These patients were subjected to a detailed clinical evaluation, laboratory assessment including blood count, hematocrit, coagulation parameters, biochemical assays, serology for dengue fever, enzyme-linked immunosorbent assay for human immunodeficiency virus and other relevant investigations.Results:Twenty-six patients with neurological complications associated with confirmed dengue infection were observed during the last 2 years. Eighteen of these patients were male. Of the 26 patients, 10 patients were suffering from brachial neuritis, four patients had encephalopathy, three patients were consistent with the diagnosis of Guillain Barre syndrome, three patients had hypokalemic paralysis associated with dengue fever and two patients had acute viral myositis. Opsoclonus-myoclonus syndrome was diagnosed in two patients, myelitis in one patient and acute disseminated encephalo-myelitis also in one patient.Conclusion:Dengue fever was associated with widespread neurological complications. Brachial neuritis and opsoclonus-myoclonus syndrome were observed for the first time in this study.

The estimated MCID score for the upper extremity motor recovery among patients with subacute stroke is 9 to 10 on the FMA-UE. Patients with subacute stroke who achieve a score of 9 to 10 on FMA-UE are more likely to experience or perceive a meaningful and clinically important improvement in their disability level than those who do not. The reference value can be used to develop goals and interpret progress in subacute poststroke patients.

BackgroundAwareness about paradoxical reactions in tuberculous meningitis is crucial as a paradoxical reaction may lead to certain wrong conclusions (for example, an erroneous diagnosis, and a possibility of treatment failure, mycobacterial drug-resistance, drug toxicity, or presence of a malignancy). The present study was planned to evaluate the incidence and predictive factors of paradoxical reactions in light of clinical, cerebrospinal fluid, and neuroimaging characteristics.MethodsIn this prospective cohort study, consecutive patients fulfilling the International Consensus criteria of tuberculous meningitis were included. Patients were subjected to clinical evaluation, cerebrospinal fluid evaluation, and neuroimaging. Patients were treated with anti-tuberculosis drugs along with corticosteroids. Patients were regularly followed up at 3 monthly intervals. At each follow up patients were evaluated clinically and repeat cerebrospinal fluid analysis was performed along with repeat neuroimaging. Disability assessment was done using Barthel index.ResultsWe enrolled 141 patients of tuberculous meningitis. Approximately one-third of patients (44/141; 31.2 %) developed a paradoxical reaction. Twenty-seven patients developed hydrocephalus, 26 developed tuberculomas, 12 developed optochiasmatic arachnoiditis and 4 patients had spinal arachnoiditis. In 41 patients (out of 44) cerebrospinal fluid paradoxically worsened (increase in cells and/or protein); 2 demonstrated a decrease in cells with polymorph predominance while in one it was normal. In 3 patients, paradoxical cerebrospinal fluid changes were not associated with neuroimaging changes. On multivariate analysis, predictors of paradoxical reaction were female gender (p = 0.013), HIV positivity (p = 0.01) and a shorter duration of illness (p = 0.049). Development of paradoxical reactions did not predict the disability status of the patients.ConclusionsParadoxical reaction occurs in approximately one-third of patients with tuberculous meningitis. Female gender, concomitant HIV infection, and a shorter duration of illness were significant predictors. Paradoxical reactions did not adversely affect the outcome.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-016-1625-9) contains supplementary material, which is available to authorized users.
