Role of vitreous cytology in the diagnosis of primary central nervous system lymphoma: A report of an unusual presentation.

Primary central nervous system lymphoma (PCNSL) is a rare subtype of non-Hodgkin lymphoma confined to the brain, spinal cord, meninges, intraocular compartment, and cranial nerves. Intraocular lymphoma (IOL) is a rare subtype of PCNSL. Intravitreal involvement by a PCNSL is an infrequent but potentially fatal event.

Rat BM-MSCs secretome alone and in combination with stiripentol and ISRIB, ameliorated microglial activation and apoptosis in experimental stroke.

Background: Stroke, a devastating neurological emergency, is the leading cause of worldwide mortality and functional disability. Combining novel neuroprotective drugs offers a way to improve the stroke intervention outcomes. In the present era, the combination therapy has been proposed as a plausible strategy to target multiple mechanisms and enhance the treatment efficacy to rescue stroke induced behavioral abnormalities and neuropathological damage.

PERK inhibitor, GSK2606414, ameliorates neuropathological damage, memory and motor functional impairments in cerebral ischemia via PERK/p-eIF2ɑ/ATF4/CHOP signaling.

The protein kinase R-like endoplasmic reticulum kinase/eukaryotic initiation factor 2ɑ (PERK/eIF2α), the branch of unfolded protein response (UPR), is responsible for transient arrest in translation to counter the enhanced levels of misfolded or unfolded proteins in the endoplasmic reticulum (ER) following any acute condition. In neurological disorders, overactivation of PERK-P/eIF2-P signaling, leads to a prolonged decline in global protein synthesis resulting in synaptic failure and neuronal death. Our study has shown, PERK/ATF4/CHOP pathway gets activated following cerebral ischemia in rats.

Cervico Medullary Junction "Intramedullary Schwannoma" Masquerading As Glioma: A Surprise During Surgery.

Background: Intramedullary schwannomas (IS) at cervicomedullary junction (CMJ) are exceedingly uncommon. There is hardly any clinicoradiological marker for preoperative diagnosis and prognostication.

Case: We report a case of a 17-year-old boy with progressive spastic quadriparesis of six months duration.

The outcome of TSHoma from a tertiary care institute in India.

Background: Thyroid-stimulating hormone (TSH)-secreting pituitary adenoma (TSHoma) is the rarest functioning pituitary adenoma.

Methods: A retrospective analysis of eight patients of TSHomas to highlight the presentations, diagnostic challenges, and treatment outcomes.

Results: Median age at diagnosis was 42 years, median latency to diagnosis was 2.

Palmoplantar Involvement in Leprosy: A Clinicopathological Study.

Palmoplantar involvement has been infrequently reported in leprosy and is an easily misdiagnosed entity. The institutional database of leprosy clinic from 2015 to 2018 was accessed. Details pertaining to demography, clinical presentation, comorbidities (if any), treatment received, and outcome were analyzed in leprosy patients with palmoplantar involvement.

Dermoscopy of Follicular Dowling-Degos Disease.

Dowling-Degos disease (DDD) is a late-onset genodermatosis characterized by hyperpigmented macules on the flexures along with scattered comedo-like lesions and pitted acneiform scars. Follicular Dowling-Degos is a rare type of DDD, with only two reports so far. It presents with follicular papules and comedo-like lesions predominantly on the face and trunk.

Proteomic Analysis of the Human Anterior Pituitary Gland.

The pituitary function is regulated by a complex system involving the hypothalamus and biological networks within the pituitary. Although the hormones secreted from the pituitary have been well studied, comprehensive analyses of the pituitary proteome are limited. Pituitary proteomics is a field of postgenomic research that is crucial to understand human health and pituitary diseases.

Imatinib Inhibits GH Secretion From Somatotropinomas.

Imatinib, a tyrosine kinase inhibitor, causes growth failure in children with chronic myeloid leukemia probably by targeting the growth hormone (GH)/insulin like growth factor-1 (IGF-1) axis. We aim to explore the imatinib targets expression in pituitary adenomas and study the effect of imatinib on GH secretion in somatotropinoma cells and GH3 cell line. The expression pattern of imatinib's targets (c-kit, VEGF, and PDGFR-α/β) was studied using immunohistochemistry and immunoblotting 157 giant (≥4 cm) pituitary adenomas (121 non-functioning pituitary adenomas, 32 somatotropinomas, and four prolactinomas) and compared to normal pituitary ( = 4) obtained at autopsy.

Which Classification of Cavernous Sinus Syndrome is Better - Ishikawa or Jefferson? A Prospective Study of 73 Patients.

Introduction: Ishikawa and Jefferson are the two most commonly used systems used for the classification of cavernous sinus syndrome (CSS). However, relative utilities of these two classification systems have not been evaluated in detail in developing countries. In this study, we compared relative utilities of these two classification schemes in the evaluation of CSS.

Clinical, demographic and immunopathological spectrum of subepidermal autoimmune bullous diseases at a tertiary center: A 1-year audit.

Background: The subepidermal autoimmune bullous diseases are a subset of immunobullous diseases encountered less frequently in the Indian population. There is a paucity of data on the prevalence, demographic and clinicopathological spectrum of various subepidermal autoimmune bullous diseases from India.

Aim: To determine the demographic and clinicopathological profile of subepidermal autoimmune bullous diseases in Indian patients, presenting to the Immunobullous Disease Clinic of Postgraduate Institute of Medical Education and Research, Chandigarh.

Predisposing factors and histopathological variants of cutaneous squamous cell carcinoma: Experience from a North Indian teaching hospital.

Background: Squamous and basal cell carcinomas together constitute the majority of non-melanoma skin cancers. These malignancies are infrequent in Indians as compared to the white skinned population. Literature on squamous cell carcinoma in dark skin is limited.

True mycotic aneurysm in a patient with gonadotropinoma after trans-sphenoidal surgery.

Background: Immunosuppressive therapy, prolonged antibiotic use, and intrathecal injections are known risk factors for the development of invasive aspergillosis. Central nervous system (CNS) aspergillosis can manifest in many forms, including mycotic aneurysm formation. The majority of the mycotic aneurysms presents with subarachnoid hemorrhage after rupture and are associated with high mortality.

Clinical profile and outcome of patients with acromegaly according to the 2014 consensus guidelines: Impact of a multi-disciplinary team.

Aim: The diagnosis and treatment of acromegaly, a rare and possibly curable disease, has undergone a paradigm shift in the past few decades. Our aim was to study the changing trends in clinical presentation, management and outcome of the disease in the last fifteen years.

Methodology: 271 consecutive patients with acromegaly treated at the Departments of Endocrinology and Neurosurgery, PGIMER, Chandigarh, between 2000 and 2014, were included in the study.

Paratesticular rhabdomyosarcoma in young adults: A tertiary care institute experience.

Introduction: Paratesticular rhabdomyosarcoma (RMS) is a rare tumor arising from the mesenchymal tissues of the spermatic cord, epididymis, testis and testicular tunics. It represents only 7% of all patients entered in the Intergroup Rhabdomyosarcoma Study (IRS) and 17% of all malignant intrascrotal tumors in children less than 15 years old. We present our experience in combined modality management of 10 successive patients of paratesticular RMS.

Is neurocysticercosis a risk factor for glioblastoma multiforme or a mere coincidence: A case report with review of literature.

Simultaneous occurrence of Neurocysticercosis (NC) along with Glioblastoma Multiforme (GBM) is a very rare presentation. We herein describe a case report of treated case of NC 2 years back who presented with secondary GBM. The brief report highlights that there may be some associated factors which may lead to development of secondary GBM in preexisting helminthic infection.
