Tacrolimus is an immunosuppressive drug used to lower the risk of transplant rejection in individuals after solid organ or hematopoietic transplantation. Cases of posterior reversible encephalopathy syndrome (PRES) as a complication of tacrolimus therapy are infrequently documented. The pathogenesis of this phenomenon is not well understood. Here, we report a case of an 18-year-old female with a history of acute myeloid leukemia that developed PRES after undergoing an allogeneic stem cell transplant and subsequent immunosuppressive therapy with tacrolimus.

Autism Spectrum Disorder (ASD) is a clinically complex, pervasive neurodevelopmental disorder with early appearing social communication deficits and repetitive sensory–motor behaviors.1 Although affected individuals differ significantly from one another, typically the disorder is characterized by impairment in social reciprocity and communication. Children usually have speech delays or lack of social interaction including: lack of eye contact, limited response to name, decreased interest in peers, and restricted shared attention with parents.1 Autistic individuals also exhibit repetitive behaviors like flapping, lining, or stacking objects and narrowly focused rigid interests such as paying particular attention to spinning objects.1 It usually manifests before 3 …

Extended Window Intravenous Thrombolysis: Is Conventional Window Of 4.5 Hours Coming To An End?, Malik Muhammad Adil, Narmeen Masood
Pakistan Journal of Neurological Sciences (PJNS)
The current standard of care to treat acute stroke patients presenting within 4.5 hours of stroke symptom onset is intravenous (IV) Alteplase.1 Over the past decade, tremendous efforts have been made to challenge the conventional window of 4.5 hours for the administration of Alteplase to expand the patient population which can benefit from thrombolysis. Based on the recent meta-analysis, 2 we have strong evidence supporting the use of IV thrombolysis in patients presenting between 4.5 to 9 hours of symptom onset with favorable perfusion imaging and it appears that the era of the conventional 4.5 hours window may be coming …

Pituitary Adenoma With Calcifications: A Case Report, 2019 Aga Khan University
Pituitary Adenoma With Calcifications: A Case Report, Yakoot Khan, Noor Malik, Saba Iqbal Awan, Syed Hassan Khalid, Altaf Ali Laghari
Section of Neurosurgery
Pituitary adenomas and Rathke’s cleft cyst with calcification are rarely seen and craniopharyngioma still remains the common sellar suprasellar space occupying lesion with calcification. Presence of calcification is reported in pituitary adenoma in only 0.2% to 8% cases. The pituitary adenoma with calcification is a rare radiological finding and it must be distinguished from other lesions of the pituitary gland as the management and prognosis differs significantly. We report a case of a 29-year-old gentleman presented electively with the complaints of deterioration of vision for four months. CT-scan without contrast examination revealed pituitary adenoma with calcification. The patient underwent transsphenoidal …

Modeling Interval Timing By Recurrent Neural Nets, 2019 CUNY Brooklyn College
Modeling Interval Timing By Recurrent Neural Nets, Theodore Raphan, Eugene Dorokhin, Andrew R. Delamater
Publications and Research
The purpose of this study was to take a new approach in showing how the central nervous system might encode time at the supra-second level using recurrent neural nets (RNNs). This approach utilizes units with a delayed feedback, whose feedback weight determines the temporal properties of specific neurons in the network architecture. When these feedback neurons are coupled, they form a multilayered dynamical system that can be used to model temporal responses to steps of input in multidimensional systems. The timing network was implemented using separate recurrent “Go” and “NoGo” neural processing units to process an individual stimulus indicating the …

Spaceflight poses many challenges for humans. Ground-based analogs typically focus on single parameters of spaceflight and their associated acute effects. This study assesses the long-term transcriptional effects following single and combination spaceflight analog conditions using the mouse model: simulated microgravity via hindlimb unloading (HLU) and/or low-dose γ-ray irradiation (LDR) for 21 days, followed by 4 months of readaptation. Changes in gene expression and epigenetic modifications in brain samples during readaptation were analyzed by whole transcriptome shotgun sequencing (RNA-seq) and reduced representation bisulfite sequencing (RRBS). The results showed minimal gene expression and cytosine methylation alterations at 4 months readaptation within single …

Human Polyomavirus Jcpyv And Its Role In Progressive Multifocal Leukoencephalopathy And Oncogenesis, Luis Del Valle, Sergio Piña-Oviedo
School of Medicine Faculty Publications
The human neurotropic virus JCPyV, a member of the family, is the opportunistic infectious agent of Progressive Multifocal Leukoencephalopathy (PML), a fatal disease seen in severe immunosuppressive conditions and, during the last decade, in patients undergoing immunotherapy. JCPyV is a ubiquitous pathogen with up to 85% of the adult population word-wide exhibiting antibodies against it. Early experiments demonstrated that direct inoculation of JCPyV into the brain of different species resulted in the development of brain tumors and other neuroectodermal-derived neoplasias. Later, several reports showed the detection of viral sequences in medulloblastomas and glial tumors, as well as expression of the …

Squamous cell carcinoma (SCC) is a common cancer of the skin. Risk factors include fair skin, excessive sun and ultraviolet light exposure, and history of xeroderma pigmentosa. Perineural invasion (PNI), an uncommon manifestation of SCC, involves microscopic tumor cells invading various layers of the nerve sheath. It is associated with a poorer prognosis. Standard treatment for PNI includes radiation therapy. Here, we describe a case an older gentleman with a history of SCC with PNI successfully treated with erlotinib and intrathecal chemotherapy.

The Effects Of Aging On Sleep Parameters In A Healthy, Melatonin-Competent Mouse Model, Jiffin K. Paulose, Chanung Wang, Bruce F. O'Hara, Vincent M. Cassone
Biology Faculty Publications
Background: Sleep disturbances are common maladies associated with human age. Sleep duration is decreased, sleep fragmentation is increased, and the timing of sleep onset and sleep offset is earlier. These disturbances have been associated with several neurodegenerative diseases. Mouse models for human sleep disturbances can be powerful due to the accessibility to neuroscientific and genetic approaches, but these are hampered by the fact that most mouse models employed in sleep research have spontaneous mutations in the biosynthetic pathway(s) regulating the rhythmic production of the pineal hormone melatonin, which has been implicated in human sleep.
Purpose and method: The present study …
Neurodevelopmental Outcomes Of Infantile Hydrocephalus: An Fmri Case Study, 2019 The University of Western Ontario
Neurodevelopmental Outcomes Of Infantile Hydrocephalus: An Fmri Case Study, Ikhlas Ahmed Hashi
Electronic Thesis and Dissertation Repository
Ventricle dilatation caused by infantile hydrocephalus may result in extensive damage of the posterior cortex (parietal and occipital lobes). We hypothesize that pathological changes in the development of the posterior cortex can be linked to non-verbal learning disabilities in children with previous infantile hydrocephalus. This case study will investigate the neurodevelopmental outcomes of 3 treated hydrocephalus patients, when compared to a group of healthy control children (n = 12). Within the hydrocephalus group, patients displayed differences in non-verbal test performance as well as parietal brain activation during an fMRI number comparison task. We associated these differences with clinical variables such …

Timing Of Postoperative Magnetic Resonance Imaging (Mri) Following Glioma Resection: Shattering The 72 Hour Window, 2019 Aga Khan University
Timing Of Postoperative Magnetic Resonance Imaging (Mri) Following Glioma Resection: Shattering The 72 Hour Window, Syed Sarmad Bukhari, Muhammad Shahzad Shamim, Fatima Mubarak
Section of Neurosurgery
Extent of enhancing tumour resection is correlated with progression free survival following glioma surgery. Historically, a contrast enhanced MRI has been recommended within 72 hours following surgery to evaluate for residual disease. This theoretical window was established amidst conflicting evidence to avoid reactive enhancement. Recent studies with better designs and better imaging quality have sought to challenge this window with a more pragmatic method of evaluating residual disease.
