Primary Ewing's Sarcoma affecting the Central Nervous System: A single-center experience and Narrative review.

Background And Objectives: Ewing's sarcoma (EWS) is a malignant round-cell tumor arising from the bone and soft tissue. It is a disease of children and young adults. EWS affecting the central nervous system (cranial and spinal column) is relatively rare with an annual incidence of approximately one case per million in the Western population.

Prolactin Secreting Pituitary Carcinoma and the Role of Peptide Receptor Radionuclide Therapy: A Brief Report.

Pituitary carcinoma is a rare entity comprising 0.1-0.2% of all pituitary tumors and presents significant diagnostic and therapeutic challenges.

Seed endophytic bacterium Lysinibacillus sp. (ZM1) from maize (Zea mays L.) shapes its root architecture through modulation of auxin biosynthesis and nitrogen metabolism.

Seed endophytic bacteria have been shown to promote the growth and development of numerous plants. However, the underlying mechanism still needs to be better understood. The present study aims to investigate the role of a seed endophytic bacterium Lysinibacillus sp.

An Unusual Origin of the Left Vertebral Artery: A Case Report.

The present paper describes a 53-year-old male who presented to the emergency department with a history of sudden chest pain followed by unconsciousness at home. The autopsy revealed the left vertebral artery (LVA)'s aberrant origin from the aortic arch between the left common carotid artery and subclavian artery in a male deceased during a medicolegal autopsy. The aortic origin of the vertebral artery is an unusual branching pattern.

Gamma Knife Stereotactic Radiosurgery for Giant Intracranial Tumors - A Series of 70 Patients.

Background And Objective: Surgery remains the primary option in large intracranial tumors, but significant number of patients may not be amenable for surgery. We explored the role of stereotactic radiosurgery as an alternative to external beam radiation therapy (EBRT) in such patients. Our study objective was to assess the clinicoradiological outcomes of large intracranial tumors (volume ≥20 cm) managed with gamma knife radiosurgery (GKRS).

Role of Gamma Knife Radiosurgery in the Management of Functional Disorders - A Literature Review.

Background: Role of radiosurgical lesioning in functional disorders has been restricted because of development of deep brain stimulation (DBS) techniques. However, many elderly patients with comorbidities and coagulation abnormalities may not be eligible for DBS. Radiosurgical lesioning may be a good alternative in such cases.

Technique of Distraction, Compression, Extension, Reduction to Reduce and Realign Old Displaced Odontoid Fracture From Posterior Approach: A Novel Technique.

Objective: Chronic 'displaced' displaced type II fractures, though uncommon, are difficult to manage. They usually require a transoral procedure followed by a posterior instrumented fusion. We describe here, a new method to reduce the fractured displaced odontoid using a posterior cervical approach only.

Evaluation of Dural Parameters at C1 Level in Patients with Chiari 1 Malformation Following Foramen Magnum and C1 Posterior Arch Removal: Introduction of a Novel Concept to Decompress without Affecting Stability.

Background: Chiari 1 malformation has crowding at craniovertebral junction (CVJ), treated by Foramen magnum decompression (FMD) but is associated with high failure rates, which is explained by recently introduced concept of central instability. So, we propose a new concept of relieving this crowding without affecting stability.

Objective: To derive a threshold for coring out of internal surface of C1 posterior arch instead of complete laminectomy accompanying FMD.

O-Arm Assisted Anterior Odontoid Screw Fixation in Type II and Rostral Type III Odontoid Fractures: Single Center Surgical Series of 50 Patients.

Background: Accuracy of screw placement is one of the important factors necessary for adequate union in odontoid fractures with malposition rates as high as 27.2% with standard techniques.

Objective: To evaluate efficacy of intraoperative O-arm assistance in improving accuracy of anterior odontoid screw placement and clinco-radiological outcome in type II and III odontoid fractures.

Single-Stage Posterior Only Approach for Unilateral Atlantoaxial Spondyloptosis with type-II odontoid Fracture in Pediatric Patients.

Objective: When there is a complete slippage of facet joints of C1 over C2 such that there is no contact between the articulating surfaces of C1 and C2, the condition is known as atlantoaxial spondyloptosis (AAS). AAS represents an extremely rare manifestation of atlantoaxial instability. This study was performed to highlight the presentation, radiological features, and management of unilateral AAS in pediatric patients.

Country-Made Firearm (Desi-Katta)-Related Cranial Injuries: An Institutional Experience.

Background: Approximately, 80% of civilian cranial gunshot injuries in India are mainly due to unlicensed mostly country-made guns, called the "Desi-Kattas," manufactured by the traditional gunsmiths. These injuries constitute a unique subgroup, with respect to the make and design along with the unique wound ballistics compared to the factory-made firearms.

Objective: This study is aimed at defining the prognostic factors in predicting the outcomes related to cranial gunshot injuries due to these desi-kattas.

Correction of pediatric cervical kyphosis with standalone posterior approach-a single-center experience of seven cases.

Purpose: To study clinical and radiological outcomes of pediatric cervical kyphosis correction with a standalone posterior cervical approach. Cervical spine kyphotic deformity in pediatric age group is a distinct entity and the management is challenging. Pediatric cervical kyphosis is less often encountered, and literature is sparse with only few case series.

Endophytic Burkholderia: Multifunctional roles in plant growth promotion and stress tolerance.

The genus Burkholderia has proven potential in improving plant performance. In recent decades, a huge diversity of Burkholderia spp. have been reported with diverse capabilities of plant symbiosis which could be harnessed to enhance plant growth and development.

Crouzon's Syndrome with a Dominant Sinus Pericranii Draining Transverse Sinus: Report of a Rare Association and Review of Literature.

Introduction: Crouzon's syndrome and sinus pericranii (SP) are rare entities. Only few cases having both the features are reported. SP most commonly drains in relation to superior sagittal sinus and their communication to major posterior dural sinuses is rare.

Use of Intraoperative Imaging to Preserve C1-C2 Mobility in Complex Atlas-Hangman Fractures.

Background: Combination fractures of the C1-C2 complex especially atlas and hangman are relatively uncommon and management usually compromises C1-C2 mobility.

Objective: To evaluate the treatment of combined C1- hangman's fracture with and without intraoperative O- arm based navigation system, and its outcome in terms of preserving C1-C2 mobility.

Methods: This was a case series of patients with combined C1 and hangman's fracture, managed at a tertiary care hospital during February 2009 to December 2016.

Surface sterilization for isolation of endophytes: Ensuring what (not) to grow.

Endophytic microbiota opens a magnificent arena of metabolites that served as a potential source of medicines for treating a variety of ailments and having prospective uses in agriculture, food, cosmetics, and many more. There are umpteen reports of endophytes improving the growth and tolerance of plants. In addition, endophytes from lifesaving drug-producing plants such as Taxus, Nothapodytes, Catharanthus, and so forth have the ability to produce host mimicking compounds.

Seed Endophytic Bacteria of Pearl Millet ( L.) Promote Seedling Development and Defend Against a Fungal Phytopathogen.

Seed endophytic bacteria (SEB) are primary symbionts that play crucial roles in plant growth and development. The present study reports the isolation of seven culturable SEB including (KAS1), (KAS2), (KAS3), (KAS4), (KAS5), (KAS6), and (KAS7) in pearl millet seeds. All the isolates were characterized for their plant growth promoting activities.
