Revisiting Post-Laminectomy Kyphosis and Challenges in Its Management: A Case Report.

The posterior ligamentous complex plays a pivotal role in spinal stability during complex movements, especially at the cervical vertebral level. Its disruption leads to the development of post-laminectomy kyphosis. The present case emphasizes the challenges in managing post-laminectomy kyphosis, restoring spinal alignment, and the importance of the posterior tension band as a spine stabilizer. A 19-year-old male underwent C2-C5 laminectomy for cervical C3 neurofibroma at an outside hospital. The patient remained stable for five months and then developed cervical kyphosis, leading to myelopathy. Clinical examination revealed significant neurological deficits, including spasticity, clonus, loss of hand dexterity, and sensory abnormalities. Imaging revealed C3 retrolisthesis with severe cervical kyphosis, cord compression, and myelomalacia. The management involved cervical traction with gradual increments in the weight and correction of the cervical sagittal balance. Principles of kyphotic deformity correction were applied, and C2 pedicle with C3-C5 lateral mass fixation was performed. The patient's modified Japanese Orthopaedic Association score improved from 10 to 16 at six months' follow-up. Post-laminectomy, the disruption of the posterior ligamentous complex increases the range of motion, particularly in the cervical spine, leading to instability and kyphosis. Surgical interventions such as laminoplasty, laminotomy, and laminectomy with posterior cervical fusion aim to mitigate the risk of kyphosis, with techniques such as bone-to-bone ligament-preserving laminoplasty and ultrasonic bone scalpel showing promise in further reducing the risk of kyphosis. The key determinant for the prevention of kyphosis is the integrity of the posterior ligamentous complex. The management of cervical kyphosis includes appropriate pre-operative planning, which includes the evaluation of cervical and spinopelvic parameters. For a posterior spinal approach, one may choose to consider laminotomy, laminoplasty, or laminectomy along with posterior cervical fusion.

Tumor Educated Platelets as a Biomarker for Diagnosis of Lung cancer: A Systematic Review.

INTRODUCTION: Lung cancer is one of the commonest cause of cancer associated mortality worldwide. Platelets have emerged as key players in cancer development and progression by supporting tumor growth, and dissemination. In the present systematic review, we analyzed RNA transfer between cancer cells and platelets and explored potential role of different platelet RNA profiles as onco-signature in diagnosis, subtyping, disease progression and treatment monitoring in carcinoma lung carcinoma. MATERIALS AND METHODS: The study followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and Cochrane Manual of Systematic Reviews and Meta-analysis that included seven studies on patients with lung cancer, with data on tumor-educated platelets, and control group. The outcome measured was based on sensitivity, specificity, and ROC. PUBMED, SCOPUS, Central Cochrane Registry of Controlled Trials and Science Direct databases were searched using specific search terms until October 2023. QUADAS - 2 tool was used to assess quality, risk of bias and applicability concerns. RESULTS: The analysis revealed AUC > 70% for different platelet mRNAs, with sensitivity and specificity of more than 60 %. AUC and sensitivity were highest for ITGA2B (AUC 0.922; sensitivity 92.8%). lncRNA GTF2H2-1 was the most specific platelet RNA. On QUADAS-2 tool, 3/7 articles were unclear in reference standards, patient flow timing, and 1/7 had high bias in both aspects. For applicability, 1/7 studies were unclear in reference standards, and 2/7 in index tests. CONCLUSION: TEP RNA can aid in early diagnosis of lung cancer and of proven utility in its early-stage detection. TEP RNA can also monitor disease progression and treatment response.

Intraventricular Tumors: Surgical Considerations in Lateral and Third Ventricular Tumors.

Management of lateral and third ventricular tumors has been a challenge for neurosurgeons. Advances in imaging and pathology have helped in a better understanding of the treatment options. Technical refinement of microsurgical technique and addition of endoscopy has enabled more radical excision of tumors, when indicated, and added more safety.A proper understanding of the pathology at various ages and treatment options is continuously evolving. Many pediatric tumors are amenable to conservative surgical methods with effective complementary treatments. However, radical surgery is required in many adults as the main treatment and for many benign tumors. Various intraventricular lesions encountered and their surgical management is reviewed here for their efficacy, safety, and outcome, encompassing changes in our practice over the last 20 years.

Nephrotic syndrome following COVID-19 vaccination: a systematic review.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 infection has caused significant morbidity and mortality. Vaccines produced against this virus have proven highly effective. However, adverse events following vaccination have also been reported. One of them is nephrotic syndrome, that can be associated with different pathologic pictures. This review aims to provide a wider understanding of incidence, etiopathogenesis, and management of nephrotic syndrome following vaccination against SARS-CoV-2. METHODS AND RESULTS: A literature search was undertaken using appropriate keywords in various databases like PubMed, Google Scholar, Europe PMC, and Science Direct. Twenty-one articles were included following qualitative assessment. Data of 74 patients from these articles were included. DISCUSSION: The pathogenesis of nephrotic syndrome following COVID vaccination has been widely attributed to the activation of angiotensin-converting enzyme-2 receptors, leading to podocyte effacement. Relapses have also been reported in patients with prior history of nephrotic syndrome following COVID-19 vaccination. A renal biopsy is necessary to identify the histopathological picture. Management of COVID-19 vaccine-induced nephrotic syndrome was mainly reported as successfully attainable with corticosteroids and supportive management. CONCLUSION: Further investigations will help in establishing an early diagnosis and salvaging kidney function.

A rare case report of Morgagni Hernia with Organo-Axial Gastric Volvulus and concomitant Para-esophageal hernia, repaired laparoscopically in a Septuagenarian.

INTRODUCTION: Simultaneous occurrence of Morgagni and the Para-esophageal hernia is a rare clinical condition with eight case reports in the English-language literature and only four managed laparoscopically. We describe a case of a Septuagenarian patient with Morgagni and concomitant Para-esophageal hernia treated laparoscopically. PRESENTATION OF A CASE: A 71-year-old male patient, presented with a one-month history of regurgitation of acid, retrosternal burning and vomiting after eating. Computed tomography (CT) imaging demonstrated a large anterior diaphragmatic hernia, with herniation of bowel loops and anterosuperior displacement of the gastric antrum along with a grade III Para-esophageal hernia. The patient underwent simultaneous laparoscopic repair of Morgagni and Para-esophageal hernia with mesh reinforcement with Nissen's total anti-reflux fundoplication. The patient's postoperative recovery was uneventful. DISCUSSION: A Morgagni Hernia is a rare congenital condition consisting of a Subcosto-sternal defect in the diaphragm. A Para-esophageal hernia is a rare variant of a hiatus hernia. Morgagni and Para-esophageal hernia may present with gastric volvulus or incarceration, requiring emergency treatment. Minimally invasive surgery is the preferred treatment, particularly for elderly patients and patients with comorbidities. The laparoscopic operation can provide excellent exposure and repair the hernia defect easily with minimal invasiveness and fewer complications. CONCLUSION: This case report highlights the co-existence of Morgagni and Para-esophageal hernias and validates the feasibility of laparoscopic repair of both hernias simultaneously.

A fatal outbreak of Trichosporon asahii sepsis in a neonatal intensive care Unit.

We describe an outbreak of Trichosporon asahii in 8 newborn infants with sepsis. Six out of these 8 infants died. The organism was identified on specific culture and morphologic characteristics. The organism was sensitive to amphotericin-B but resistant to fluconazole. Laminar flow unit was suspected to be the source of the outbreak.
