Cutaneous Manifestations and Neurological Diseases.

Our skin and nervous system are tightly connected. Numerous dermatomes on our skin provide sensory information to the brain. Because skin changes can occasionally be the first sign of a neurological problem, understanding skin alterations is crucial as it can indicate early about the underlying condition, which can affect the prognosis of the disease. In these cases, the dermatologists' and neurologists' skills are complementary to each other. In this article, we have categorized diseases with neuro-cutaneous manifestations under different headings, such as infections, metabolic diseases, connective tissue disorders, genodermatoses, nutritional deficiency, and the diagnostic criteria of some commonly encountered diseases. Through tabulation, it has been observed that this categorization can serve as a useful reference for managing day-to-day patients who are either diagnosed with the diseases mentioned above or suspected to have the conditions.

Techniques for Diagnosing Anastomotic Leaks Intraoperatively in Colorectal Surgeries: A Review.

Colorectal cancer is one of the most common surgically curable malignancies worldwide, having a good prognosis even with liver metastasis. This improved patient outcome is marred by anastomotic leaks (AL) in operated patients of colorectal cancer despite a microscopically margin-negative resection (R0). Various risk factors have been attributed to causing this. Preoperative non-modifiable factors are age, male sex, cancer cachexia, and neoadjuvant chemo-radiotherapy, and modifiable factors are comorbidities, peripheral vascular disease, anemia, and malnutrition. Intraoperative risk factors include intraoperative surgical duration, blood loss and transfusions, fluid management, oxygen saturation, surgical technique (stapled, handsewn, or compression devices), and approach (open, laparoscopic, or robotic). Postoperative factors like anemia, infection, fluid management, and blood transfusions also have an effect. With the advent of enhanced recovery after surgery (ERAS) protocols, many modifiable factors can be optimized to reduce the risk. Prevention is better than cure as the morbidity and mortality of AL are very high. There is still a need for an intraoperative technique to detect the viability of anastomotic ends to predict and prevent AL. Prompt diagnosis of an AL is the key. Many surgeons have proposed using methods like air leak tests, intraoperative endoscopy, Doppler ultrasound, and near-infrared fluorescence imaging to decrease the incidence of AL. All these methods can minimize AL, resulting in significant intraoperative alterations to surgical tactics. This narrative review covers the methods of assessing of integrity of anastomosis during the surgery, which can help prevent anastomotic leakage.

Emerging Recombinant Oncolytic Poliovirus Therapies Against Malignant Glioma: A Review.

Glioblastoma multiforme (GBM) is a fourth-grade malignant glioma that continues to be the main contributor to primary malignant brain tumour-related death in humans. The most prevalent primary brain tumours are gliomas. The most dangerous of these neoplasms, GBM, has been shown to be one of the most lethal and refractory tumours. For those who have been diagnosed with GBM, the median time to progression, as determined by magnetic resonance imaging, is roughly six months, and the median survival is approximately one year. GBM is challenging to manage with old treatments like chemotherapy, tumour debulking, and radiation therapy. Treatment outcomes are poor, and due to this effect, the treatment is not up to the mark. GBM also shows diagnostic complexity due to limitations in the use of specific targeted therapies. The treatment protocol followed currently has an entire focus on safe resection and radiotherapy. Protein synthesis is not tightly regulated physiologically in malignant cells, which promotes unchecked growth and proliferation. An innovative, experimental technique for treating cancer uses polioviruses that have been genetically altered to target a fascinating aberration of translation regulation in cancer. This approach enables precise and effective cancer cell targeting based on the convergence of numerous variables. Oncolytic viruses have revolutionised cancer treatment. However, their effectiveness in glioblastoma remains restricted, necessitating more improvement. Oncolytic poliovirus has shown great potential in the treatment of GBM. Factors like the blood-brain barrier, immunosuppressive tumour microenvironment (TME), and tumour heterogeneity make treatment for malignant gliomas ineffective. In this review, we have focused on oncolytic viruses, specifically oncolytic poliovirus, and we explore malignant glioma treatments. We have also discussed currently available conventional treatment options for malignant glioma and other brain tumours.

Decompressive Craniectomy in the Management of Low Glasgow Coma Score Patients With Extradural Hematoma: A Review of Literature and Guidelines.

An extradural hematoma (EDH), also known as an epidural hematoma, is a collection of blood between the inner skull table and the dura mater. It is restricted by the coronal, lambdoid, and sagittal sutures, as these are dural insertions. EDH most frequently occurs in 10- to 40-year-old patients. EDH is uncommon after age 60, as dura matter adheres firmly to the inner skull table. EDH is more common among men as compared to women. EDH most commonly occurs in the temporo-frontal regions and can also be seen in the parieto-occipital, parasagittal regions, and middle and posterior fossae. An EDH contributes approximately 2% of total head injuries and 15% of total fatal head injuries. In EDH, patients typically have a persistent, severe headache, and also, following a few hours of injury, they gradually lose consciousness. The primary bleeding vessels for EDH are the middle meningeal artery, middle meningeal vein, and torn dural venous sinuses. EDH is one of the many consequences of severe traumatic brain injuries that might lead to death. EDH is potentially a lethal condition that requires immediate intervention as, if left untreated, it can lead to growing transtentorial herniation, diminished consciousness, dilated pupils, and other neurological problems. Non-contrast computed tomography (NCCT) imaging is the gold standard of investigation for diagnosing EDH. For patients with surgical indications, early craniotomy and evacuation of acute extradural hematoma (AEDH) is the gold standard procedure and is predicted to have significant clinical results. Nevertheless, there is an ongoing debate regarding the best surgical operations for AEDH. Neurosurgeons must choose between a decompressive craniectomy (DC) or a craniotomy to manage EDH, especially in patients with low Glasgow coma scores, to have a better prognosis and clinical results. This is a consultant-based review article in which we have tried to contemplate various pieces of available literature. Here, the objective is to hypothesize DC as the primary surgical management for massive hematoma, which usually presents as a low Glasgow coma score. This is because DC was found to be beneficial in clinical practice.
