Juniper Publishers- Symptomatic, Operable Tarlov Cysts: A Myth or a Reality?

Symptomatic, Operable Tarlov Cysts: A Myth or a Reality?

Authored by Vibhu Krishnan Viswanathan The presence of perineural cysts within the sacral spinal canal was initially described in the literature as early as 1938, when Tarlov had identified a similar lesion during one of his autopsies. While a majority of these lesions are asymptomatic and represent incidental findings observed on MRIs or CT scans, there have been described rare instances in the literature, when these lesions have resulted in symptoms which required surgical intervention. Coccygodynia, dyspareunia, perianal pain and cauda equina syndrome have been described as definitive indications for surgery. However, the role of surgery in relieving back pain or radicular symptoms following Tarlov cysts has remained controversial. The current article describes a similar lesion observed in one of our patients. The purpose of this report is to highlight the fact that tarlov cyst can definitely be a potential cause for back and leg symptoms in certain patients and surgical decompression in the form of complete cyst excision along with the walls may be considered a safe and effective option after failure of conservative trial.

Juniper Publishers| The Anatomical Architecture of the Junction between the Great Cerebral Vein and the Straight Sinus in Correlation to the Physiological and Biochemical Impact on Multiple Sclerosis Subtypes and Disease Progression- A Review Article

  Journal of Surgery -  JuniperPublishers Abstract Introduction:  Multiple Sclerosis (MS) is a debilitating autoimmune disorder, characterized by damage to the white matter of the central nervous system. Studies suggest a relationship between impaired cerebral venous blood flow and progressive destruction of white matter in the CNS. Altered cerebral venous architecture is a possible mechanism that may contribute to a compromised venous blood flow pattern in MS patients. Natural variations at junction located between the great cerebral vein (GCV) and the straight sinus (Ss) located within the cerebral venous drainage system can potentially exacerbate MS progression. Recent data indicates that abnormal cerebral venous hemodynamics contributes to the pathophysiology observed in MS through an unknown mechanism that increases hydraulic resistance. Objective:  This review aims to investigate if anatomical variations at the GSV and Ss junction elicit a profound effect on the cerebral venous s

Juniper Publishers| The Use of the Second-Generation Protein Kinase Inhibitors in Patients with Gastrointestinal Stromal Tumor with Failure to the Treatment with Imatinib

  Journal of Surgery -  JuniperPublishers Introduction:  Gastrointestinal Stromal Tumor (GIST) is considered the most common mesenchymal tumor of the gastrointestinal tract. Approximately 85% of GISTs have mutations in proto-oncogene KIT encoding, a tyrosine kinase receptor. About 8% of GISTs are associated to mutations in the growth factor receptor alpha (PDGFRA) gene. The standard treatment of GIST is the surgical resection of the tumor. In cases of metastasis and tumor recurrence specific drugs as tyrosine kinase inhibitors are used. The first line treatment is Imatinib. Although the treatment with imatinib failed in some patients for the metastatic and relapsed treatment of GIST, the patients can to use other drugs, called second generation. Discussion:  One of the great advances in the diagnosis of GIST was the recognition through the immunohistochemistry of the c-Kit marker. The tyrosine kinase inhibitor, imatinib, has become the standard treatment for those, with high-risk resec
