Telemedicine in Follow-up after Spine Surgery: Need of the Hour.

 There is an acute shortage of neurosurgeons and spine surgeons especially in rural areas of low- and middle-income countries including India. Patients of spine surgery need to travel long distances for follow-up at tertiary care hospitals. This study was done to evaluate role and success rate of telemedicine in follow-up after spine surgery based on patients' diagnosis and demographic features and to identify barriers to successful telemedicine consultations.

Use of cost-effective software for lesion localization in brain surgery: Technical note.

Lesion localization has been an important aspect of neurosurgery and has advanced significantly with technological evolution. The journey started from the localization of lesion based on clinical findings to the current era where neuronavigation and virtual reality are being used for the purpose. However, the financial implications of these advanced equipments have made them inaccessible for patients in the majority of low- and middle-income countries.

"Genome-wide identification of bZIP gene family in Pearl millet and transcriptional profiling under abiotic stress, phytohormonal treatments; and functional characterization of ".

Abiotic stresses are major constraints in crop production, and are accountable for more than half of the total crop loss. Plants overcome these environmental stresses using coordinated activities of transcription factors and phytohormones. Pearl millet an important C4 cereal plant having high nutritional value and climate resilient features is grown in marginal lands of Africa and South-East Asia including India.

Manual Instruments as an Alternative to Drilling for Bony Exposure in Skull Base Surgery: Concept and Technique.

 Drilling in neurosurgery is an integral part of surgical exposure, especially in skull base approaches and craniovertebral junction (CVJ) surgeries. Most of such drillings are done in close proximity to the neurovascular structures in skull base surgeries and cervical-medullary junction or facet/pedicle in CVJ surgeries. Reluctance to drilling among young neurosurgeons is due to less hands-on experience during training and also, in the early part of the career, due to fear of injury to neurovascular structures.

Optochiasmatic Cavernomas: Updated systematic review and proposal of a novel classification with surgical approaches.

Cavernomas are histologically benign vascular malformations found at different sites in the brain. A rare site for such cavernomas, however, is the anterior optic pathway, comprising the optic nerve, chiasma, and optic tract-called optochiasmatic cavernomas (OCC). These lesions usually present with sudden onset or progressive vision loss, headache, and features mimicking pituitary apoplexy.

Morphometric Comparison of Endoscopic Endonasal Transpterygoid and Precaruncular Contralateral Medial Transorbital Approaches to Sphenoid Sinus Lateral Recess.

Background And Objectives: The endoscopic endonasal transpterygoid approach (TPA), minimally invasive compared with the sublabial transmaxillary and transcranial approaches, still accounts for morbidity in benign lateral recess of sphenoid sinus (LRSS) pathologies. Others have suggested an alternative route to the LRSS, the endoscopic contralateral medial transorbital approach (cMTO). However, no quantitative evidence exists to support the clinical application of this approach.

Setting Up a Department of Neurosurgery in a Government Hospital in an LMIC: Jodhpur, India.

Background: The number of government institutes offering affordable super specialty and tertiary healthcare in India has traditionally not been able to keep pace with the growth in population, most of whom are too poor to be able to afford private healthcare services. To meet this mandate, 6 new institutes built on the template of the premier institute of the country-the All India Institute of Medical Sciences, New Delhi-were founded and began operations in 2012. Using the progress of our department as an example, the aim of this report is to outline the principles that were followed to set up the department of neurosurgery.

Introduction: The objective of this study was to compare 99mTc MIBI myocardial perfusion SPECT and Dobutamine Stress Echocardiography (DSE) in detecting viable myocardium in patients with Coronary Artery Disease.

Materials And Methods: Total of 50 patients who with CAD and poor LV function were idenitifed on 2D Echo using 16 segment cardiac model. These patients underwent 99mTc MIBI myocardial perfusion SPECT and Dobutamine Stress Echocardiography and the results were compared with the gold standard 18F-FDG PET-CT findings.

Use of Multimodality Intraoperative Neuromonitoring in Tethered Cord Syndrome - Experience from a Tertiary Care Center.

Detethering of the spinal cord is done in nearly all cases of tethered cord syndrome (TCS), which can damage nerve roots, and hence, there is a need to identify filum terminale during surgery. Multimodality intraoperative neuromonitoring (IONM) may be useful in this regard to prevent postoperative morbidity. Twenty-six patients (13 males and 13 females, age range: one year to 56 years) with TCS were recruited for the study.

The status of COVID-19 vaccines in India: A review.

The outbreak of SARS-CoV-2, an etiologic agent of the COVID-19 pandemic disease in late December 2019 has left the whole world aghast with huge health and economic losses. Due to a lack of specific knowledge and understanding at the initial stages, an unprecedented rise in COVID-19 cases has been recorded globally. Various preventive measures and strategies were implemented, however, for the radical control of SARS-CoV-2 infections; it seems that the only effective way to control the ongoing infections is large-scale vaccination.

Skull base dural reflection models: tool for teaching neuroanatomy at resource-scarce centers.

Skull base dural reflections are complex, and along with various ligaments joining sutures of the skull base, are related to most important vessels like internal carotid arteries (ICA), vertebral arteries, jugular veins, cavernous sinus, and cranial nerves which make surgical approaches difficult and need thorough knowledge and anatomy for a safe dissection and satisfactory patient outcomes. Cadaver dissection is much more important for the training of skull base anatomy in comparison to any other subspecialty of neurosurgery; however, such facilities are not available at most of the training institutes, more so in low- and middle-income countries (LMICs). A glue gun (100-Watt glue gun, ApTech Deals, Delhi, India) was used to spread glue over the superior surface of the bone of the skull base over desired area (anterior, middle, or lateral skull base).

Mucous Extractor for Tumor Tissue Sampling in Neurosurgery.

 Collection of sample for histopathological analysis is highly important during any surgical procedure. The histopathology report helps determine the diagnosis, prognosis further management, and follow-up plan. The use of a reliable sample collection technique is doubly important in neurosurgical procedures because lesions are often deep-seated and difficult to access.

Genome sequence analysis of nsp15 from SARS-CoV-2.

SARS-CoV-2 (Severe Acute Respiratory Syndrome), a causative agent of COVID-19 disease created a pandemic situation worldwide. Nsp15 is a uridine specific endoribonuclease encoded by the genome of SARS-CoV-2. It plays important role in processing viral RNA and, thus evades the host immune system.

Suction cannula design for safe microneurosurgery.

Introduction: Suction cannula (SC) is an important instrument for a neurosurgeon. Currently used suction control valves, kept in the sterile field, are controlled by the surgeon, for which he needs to leave the surgical dissection or by assistant or by operation room personnel to adjust the pressure of the equipment (suction machine or central suction), which lies in the unsterile field. Authors studied relationships of the different diameters of SC and the thumb hole (TH) of the SC and present their findings.

MYB Transcription Factor Family in Pearl Millet: Genome-Wide Identification, Evolutionary Progression and Expression Analysis under Abiotic Stress and Phytohormone Treatments.

Transcription factors (TFs) are the regulatory proteins that act as molecular switches in controlling stress-responsive gene expression. Among them, the MYB transcription factor family is one of the largest TF family in plants, playing a significant role in plant growth, development, phytohormone signaling and stress-responsive processes. Pearl millet ( L.

Synthetic sub-genomic transcript promoter from Horseradish Latent Virus (HRLV).

We characterized an efficient chimeric sub-genomic transcript promoter from Horseradish Latent Virus, FHS4, active in both dicot and monocot plants, and it could be a potential tool for plant biotechnology. Plant pararetroviruses are a rich source of novel plant promoters widely used for biotechnological applications. Here, we comprehensively characterized a unique sub-genomic transcript (Sgt) promoter of Horseradish Latent Virus (HRLV) and identified a fragment (HS4; - 340 to + 10; 351 bp) that showed the highest expression of reporter genes in both transient and transgenic assays as evidenced by biochemical, histochemical GUS reporter assay and transcript analysis of uidA gene by qRT-PCR.

New Late Cretaceous titanosaur sauropod dinosaur egg clutches from lower Narmada valley, India: Palaeobiology and taphonomy.

The Upper Cretaceous (Maastrichtian) Lameta Formation is well-known for its osteological and oological remains of sauropods from the eastern and western parts of the Narmada Valley, central India. The newly documented ninety-two titanosaur clutches from Dhar District (Madhya Pradesh State, central India) add further to this extensive data. Previously parataxonomy of these titanosaur clutches was carried out with a few brief reports on palaeobiological and taphonomic aspects.

Handmade models for aneurysm surgery: A useful tool for training.

Background: Aneurysm surgery is considered difficult by young and trainee neurosurgeons. This is due to difficulty in understanding orientation of aneurysm complex (proximal and distal vessels, aneurysm neck, and fundus) in relation to the surrounding structures (skull, brain, vessels, and nerves) after head is rotated, extended, and fixed on the head frame. Virtual three-dimensional (3D) imaging studies and 3D-printed models help young neurosurgeons but are not accessible to most of the centers due to need for resources (human and equipment).

Inguinal Lymphadenopathy: A Rare Initial Site of Metastatic Lung Carcinoma.

Solid-organ tumors involving inguinal lymph nodes commonly originate from genitourinary tract, skin, ano-rectum, or the urinary bladder. Thus, solitary metastatic involvement of inguinal lymph nodes from extra-abdominal primary malignancies is extremely rare. However, involvement of nonregional lymph nodes upstages the disease to M1b with poor prognosis.

The Yin and Yang of Operating on a Posterior Fossa Meningioma: The Schmahmann Syndrome.

The cerebellum is classically linked with control of motor function, such as coordination, balance, and regulation of movement. There is an increasing awareness, now, of the non-motor functions of the cerebellum, and the occurrence of behavioral anomalies with cerebellar disorders. We present the first report of Schmahmann syndrome (cerebellar cognitive affective syndrome [CCAS]) occurring secondary to posterior fossa meningioma excision.
