Background: Complex regional pain syndrome (CRPS) is a chronic pain condition characterized by autonomic and inflammatory features. There is paucity of data regarding sustained benefits of any treatment modality. We aimed to document the effect of steroids in CRPS on long-term basis.Materials and Methods: We came across five patients of CRPS in Out Patient clinics of super-speciality Institutes in North India. All five cases fulfilled the Budapest criteria for the diagnosis of CRPS. All of them received prednisolone and were prospectively followed up for 2 years. Treatment outcome was carefully recorded in all affected modalities.Results: All five cases were found to have excruciating neuropathic pain in defined regions along with cutaneous manifestations. Osseous changes in the form of surface erosion of underlying bones in four cases and marked marrow edema leading to considerable increase in bone thickness in one case were noted. All these features improved considerably following steroid therapy. Bone marrow edema and bone resorption showed improvement on serial imaging.Conclusion: Apart from pain relief, steroids therapy is capable of reversing the osteo-cutaneous autonomic changes of CRPS type I.

BACKGROUND: Recurrent strokes cause greater complications and worse outcomes by adding to the existing neurological deficit. There is the paucity of data on serum markers of inflammation as predictors of recurrent stroke. This study was planned to analyze the clinico-etiological profile of recurrent noncardioembolic ischemic stroke, estimate aspirin resistance among regular aspirin users and evaluate blood biomarkers high-sensitivity C-reactive protein (hsCRP), Tumor necrosis factor-alpha (TNF-a), Lipoprotein-associated phospholipase A2 (Lp-PLA2) as probable predictors of stroke recurrence. METHODS: Patients of recurrent noncardioembolic ischemic stroke fulfilling the inclusion criteria were enrolled. Detailed history, clinical examination, and investigations were obtained as per protocol. Aspirin resistance was determined by light transmission aggregometry. Serum hsCRP, TNF-a, and Lp-PLA2 levels were estimated. RESULTS: This study included 34 males and 16 females. Majority of the patients were > 60 years (n = 30, 60%). Thirty (60%) cases had a repeat stroke after 1 year of primary event. Thirty-nine (78%) study participants had hypertension, while 15 (30%) had diabetes. Middle cerebral artery (n = 40, 80%) was the most common vascular territory. Thirty-one (62%) cases belonged to TOAST subtype 1 (large artery atherosclerosis). Seventy two percent cases were prescribed aspirin after index stroke, but only 36% were compliant. Median (range) hsCRP level was 7.5 (0.3-155) mg/L with 72% of patients having high hsCRP level (>3 mg/L). Median (range) serum PLA2 level was 11.98 (3.31-87.24) ng/ml in patients and 6.96 (0.15-61.42) ng/ml in controls (P = 0.029). Median (range) serum TNF-a level in patients was significantly higher than controls (68.22 [1.3-287] pg/ml versus 0.098 [0.002-36.31] pg/ml, P < 0.001). Aspirin resistance was found in 41.7% patients while 16.7% were semi-resistant. Mean % platelet aggregation was 34.75 ± 21.58 in patients and 64.75 ± 16.98 for controls (P < 0.001). CONCLUSIONS: Majority of patients with recurrent stroke were elderly (>60 years), hypertensive, and non-compliant with aspirin. Aspirin resistance was an important factor in patients with antiplatelet compliance. Inflammatory biomarkers hsCRP, PLA2, and TNF-a were found to be significantly elevated in patients compared to controls. [ABSTRACT FROM AUTHOR]

Background: Subacute Sclerosing Pan Encephalitis (SSPE) may present with atypical clinical features and lead to diagnostic dilemma. Conventional magnetic resonance imaging (MRI) may be normal in early stage of SSPE., Objective: The aim of this work was to study the demography, clinical profile including atypical features of SSPE patients, and the utility of diffusion tensor imaging (DTI) as an adjunctive diagnostic tool to the anti-measles antibody and conventional MRI., Material and Methods: Consecutive 25 patients of SSPE were included. Clinical details were recorded at baseline and 6 months follow-up. Anti-measles antibody in serum and CSF, CSF/Serum Quotient reference (CSQ ref), and radiological details including comparison of DTI between SSPE patients and controls were also noted., Results: Of 25 patients, 17 (68%) were male. The most common presenting feature at onset was myoclonus with or without falls (13, 52%). Atypical features such as seizure, hemiparesis, and visual problems were present in 28% patients. At 6 months, 9 patients had progressive course (6 expired), 10 were static, and 6 lost to follow-up. MRI was normal in 8 (32%) patients (stage 2/3- 7/1). On comparison between SSPE patients (N = 10) and control (N = 10) groups, fractional anisotropy (FA), and apparent diffusion coefficient (ADC) values were reduced and elevated, respectively, at most of the regions of interest with significant difference at many sites., Conclusions: A significant number of patients (28%) had atypical features at onset. DTI is an adjunctive tool which supplements the conventional MRI and increase diagnostic yield. It may be a future option to assess disease progression and treatment response., Competing Interests: None
