The diagnosis of spinal cord infarction should always be kept in mind.
A case report with a review of the current literature concerning cutaneous necrosis has occasionally been reported in interferon therapy.
We report a 19-year-old woman diagnosed multiple sclerosis for three years. She selfinjected the standard dose of recombinant interferonβ-1a (12 million units) subcutaneously three times a week. Severe necrotizing cutaneous reactions over abdomen Happened and she must receive parental antibiotics and surgical debridement.
Our observation emphasizes the importance of educating patients on the proper selfadministration of subcutaneous injections of interferon β.

Focal signs are a big deal in neurology and are among the most important clues leading to diagnosis and localization. Wernekink commissure syndrome is due to lesions in the caudal paramedian midbrain involving the entire decussation of the superior cerebellar peduncles, resulting in the clinical hallmark of a bilateral cerebellar syndrome.
A 79-year-old man presented with sudden, severe unsteadiness associated with slurring of speech, binocular double vision, and bilateral hand tremor. Examination showed right INO, moderately severe dysarthria, bilateral dysmetria and dysdiadochokinesia, with severe truncal ataxia and bilateral upper and lower limb ataxia. Also, bilateral coarse tremor was noted in both hands which was present at rest, action and on reaching for objects. Brain MRI revealed an acute infarction involving the Wernekinck decussation in the right caudal midbrain and mesencephalo-pontine junction.
The differential of Wernekink Commissure Syndrome is complex, and localization and lateralization are extremely difficult owing to prominent bilateral cerebellar symptoms. The finding of an associated unilateral INO in some cases makes it possible to confidently narrow the list of differentials and localize the lesion to the paramedian tegmentum ipsilateral to the non-adducting eye.

MR perfusion weighted imaging (PWI) has been used as sensitive indicator of tissue at risk for infarction. Quantitative perfusion parameters such as cerebral blood flow (CBF), mean transit time (MTT) and cerebral blood volume (CBV) can be obtained from post processing of PWI data using standard singular value decomposition algorithm (SVD). Assumption regarding absence of arterial - tissue delay (ATD) used in SVD algorithm results in underestimation of perfusion parameters. To estimate accurate values for perfusion parameters it is important to understand the mathematical framework behind SVD and improved SVD algorithms (bSVD and rSVD).
This study explains the mathematical framework of SVD and improved SVD algorithms and uses computational techniques that use bSVD algorithm to obtain perfusion parameters maps of CBF, CBV and MTT for acute stroke patient.
Computational techniques based on mathematical deconvolution algorithms are used to post process CBV, CBF and MTT maps where decrease in CBF and CBV were seen in left hemisphere.
The bSVD algorithm is found to be sensitive to ATD and provides more accurate estimates of perfusion parameters than the SVD algorithm, however CBF estimates from bSVD and rSVD still remain influenced by other artifacts Keywords PWI = perfusion weighted imaging, CBF= cerebral blood flow, MTT = mean transit time, CBV= cerebral blood volume, SVD = singular value decomposition algorithm.

The patients with more severe stroke, have more chance to develop higher levels of cognitive impairments; and family history of dementia as a genetic background, can give rise to an increased risk of the severity of cognitive deterioration. In this study, we sought to investigate whether the risk alleles of Val66Met of brain-derived neurotrophic factor (BDNF) polymorphism, has a destructive interaction with the stroke severity (SS) and family history of dementia (FHD) for cognitive impairments?
In a case-control study, the carriers of at least one Val allele (n=56) were compared to the carriers of Met/Met homozygotes (n=156) in terms of FHD and SS (through National Institutes of Health Stroke Scale) on the north of Iran. To determine the cognitive functions, the third version of Addenbrooke's Cognitive Examination (ACE-III) was used.
The mean age of patients was 64.52±11.71, and in average 202 day had passed from their stroke. click here The interactive effects of genotypes Val66Met BDNF with SS[F=8.95, ή2=0.04, Ptrategy in reducing the cognitive impairments following the stroke.A 22-year-old man was referred for upper abdominal pain. Unenhanced computed tomography (CT) revealed a lesion of heterogeneous hypoattenuation, part of which showed slightly high-density in the porta hepatis. On magnetic resonance imaging (MRI), T1-weighted images showed a multiloculated hyperintense mass and part of the mass was hyperintense in T2-weighted images. Abdominal ultrasonography showed a 40 mm multilocular mass with septa, containing solid and small cystic components. In sonazoid-enhanced ultrasonography, the septa were enhanced but the solid components were not. Because of the location of tumor and the findings of CT/MRI, we suspected the lesion as hematoma of the liver. We could not exclude neoplastic disease, such as biliary cystadenoma or cystadenocarcinoma of the liver, so surgical resection was performed. The mass was a multilocular cyst arising from the hepatoduodenal ligament. Pathological examination revealed aggregation of lymph vessels and endothelial-like cells with no atypia, which were positive for the specific markers D2-40 and CD31.
