Abstract Objective: Neurotrauma has been labelled as a “silent epidemic” affecting both the developed and the developing nations. To date, no single brain-specific biomarker has been unanimously accepted for routine clinical use in TBI. Our study aims to determine the correlation of “cleaved-tau protein” in severe traumatic brain injury (TBI) with Glasgow Coma Scale (GCS) at the time of admission, mode of injury, CT findings and outcome at discharge. Methods: The study has been approved by the institutional ethical committee. 40 cases with severe TBI and 40 randomly selected healthy controls were included in this prospective study. Venous blood samples were collected and serum cleaved tau protein levels were measured and correlated with gender, mode of injury, CT findings GCS score and GOS score at discharge. Results: In the severe TBI group, the mean serum cleaved tau protein levels in males were 91.65 ± 41.34 pg/ml (mean ± S.D.), and females were 104.43 ± 53.08 pg/ml (mean ± S.D.), (p = 0.27). Mean serum C-tau level in study group was 95.48 ± 44.87 pg/ml (range 36.44-192.34), 95% C.I. (81.13–109.83) and in controls was 33.82 ± 13.65 pg/ml (range 2.48–66.54), 95% C.I. (29.46–38.19) (p < 0.001). The distribution of serum C-tau was in severe TBI group varied in all categories of GCS at 0th day (p < 0.001). Serum cleaved tau protein levels in the good outcome group were 74.26 ± 25.43 pg/ml (mean ± S.D.), range 36.44–144.54, 95% C.I. (63.52-85.00) and the poor-outcome group were 127.32 ± 49.40 pg/ml, range 66.65–192.34, 95% C.I. (100.99-153.64) (p = 0.001). Conclusion: In severe TBI, serum cleaved tau protein levels were significantly higher as compared to the controls in this prospective study. However, results of this study are preliminary in nature and there is a need to undertake larger prospective studies to reach a definitive conclusion.

Pulmonary alveolar microlithiasis is a rare disease characterized by intra-alveolar presence of microliths. This study reports an interesting case of pulmonary alveolar microlithiasis and provides a systematic review of cases reported from India. A 23-year-old female presented with a history of cough, wheeze, chest pain, and episodic wheeze for five months. Pulmonary function tests demonstrated an obstructive pattern, and chest Xray showed fine micronodular opacities predominantly involving the middle and lower zones of both lungs. Transbronchial lung biopsy revealed the diagnosis. She responded well to inhaled steroid therapy. A systematic review of literature was performed and identified 73 cases of pulmonary alveolar microlithiasis reported from India. The mean (SD) age of the patients was 28.8 (14.9) years, with an almost equal male:female ratio. Many patients were asymptomatic at presentation. Breathlessness and cough were the most common symptoms, and the disease progressed into respiratory failure associated with cor pulmonale. About one-third of the cases were initially misdiagnosed and treated as pulmonary tuberculosis. Extra-pulmonary manifestations and comorbidities were also evident in our series. This systematic review helps to determine epidemiological and clinical characteristics of pulmonary alveolar microlithiasis. Further research is needed to elucidate the etiopathogenesis, diagnosis, and therapeutic options, which are beneficial in developing and identifying costeffective treatment for pulmonary alveolar microlithiasis.

Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder characterised by various phenotypic features like hyperpigmented spots, neurofibromas, Lisch nodules, skeletal abnormalities and tendency to develop neoplasms. Only few cases of Non-Familial Spinal Neurofibromatosis-1 (Non-FSNF1) have been described in literature with tumors involving the spinal roots at every level being even rarer. We reported an interesting case of bilateral symmetrical cervical neurofibroma with multiple spinal neurofibromas appearing as mirror image on CT, associated with non familial NF-1 as a rare presentation in a 25-year-old adult male.

Acquired dorsal intraspinal epidermoid cyst in an adult female

Kulwant Singh; Sharad Pandey; Praveen Kumar Gupta; Vivek Sharma; Deepa Santhosh; Amrita Ghosh

Background: Epidermoid and dermoid cyst comprise <1% of spinal tumors and may be congenital (hamartoma) or acquired (iatrogenic) in origin. Epidermoid cysts within the neuraxis are rare benign neoplasms that are most commonly located in the intracranial region. Case Description: Here, we report the a case of an acquired intradural extramedullary epidermoid cyst involving the thoracic region in an adult female who had no associated history of an accompanying congenital spinal deformity. Conclusion: Early diagnosis and immediate surgical intervention reduce patient morbidity. Near complete or subtotal excision of the cyst wall is warranted to prevent inadvertent injury to the spinal cord thus minimizing neurological morbidity.

A Comparative Study of Endoscopic Versus Navigation Guided Microscopic Transsphenoidal Pituitary Surgery at Tertiary Care Centre in India

Anurag Sahu; Sharad Pandey; Kulwant Singh; Vivek Sharma

Abstract Introduction: The transsphenoidal route for pituitary surgery is considered the standard treatment for pituitary adenomas. The disadvantage of the smaller exposure of this route is partially compensated for by the introduction of the microscope with its coaxial illumination, stereoscopic view, adequate magnification, and microsurgical instruments. However, there are only few reports about the outcome of endonasal endoscopic transphenoidal technique. Aims & Objectives: Current study has been conducted to compare the efficacy, advantages and dis advantages of endoscopic versus navigation guided microscopic transsphenoidal Pituitary surgery. Material and methods: A controlled study was done in the department of neurosurgery, at tertiary care hospital in India, from the period of August 2012 to December 2017 prospectively. In Group A- 30 patients in whom endoscopic transnasal trans Sphenoidal pituitary surgery and in Group B - 30 patients, intraoperative neuronavigation was used. Observations and Results: Both the groups were similar in demographic variables. The most common age group of pituitary tumor patients was 30-40 years. Fourteen (46.6 %) patients in group A and fifteen (50 %) of the patients in group B had tumor volume less than 5 ml. In group A, thirteen (43%) patients had intrasellar tumors with no suprasellar extension, while in group B, fifteen (50%) patients had intrasellar tumors with no extension. Operative time was noted from incision to closure and average time taken in both the groups was compared. Twenty five (83%) cases of group A took between 2-3 hours and only four cases (13%) took more than 3 hours. While in group B, twenty (66%) cases took between 4-5 hours. This shows a significant difference by fisher extact test (p<0.001) in the operative time required in both the groups. Eighteen (60%) patients in group B had a residual volume between 1-1.5 ml while only two patients in group A had so. This difference is also significant Fischer Exact test (p<0.001). Four (13.3%) patients in group A had diabites insipidus while only half of this, i.e. two (6.6%) had so in group B. however this difference in postoperative complication rate is not statistically significant between two groups. Conclusion: The results of our study correlate with many previous studies to compare endoscopic and microscopic transsphenoidal surgery. These two approaches are equally efficacious in oncological outcomes and the complication rates are comparable.

Ipsilateral double extradural hematoma in a child: An uncommon case

Sharad Pandey; Kulwant Singh; Vivek Sharma; Deepak Bhanudas Patil

Double extradural hematomas (DEDH) comprise 2-10% of all extradural hematomas (EDH). The ipsilateral occurrence of more than one EDH is quite uncommon. We are reporting a case of ipsilateral DEDH in a 10-year-old child following a head injury. Though DEDH is extremely lethal and a rare diagnosis, ipsilateral DEDH is still uncommon. Furthermore, the occurrence of EDH in the pediatric age group is quite unusual. As compared to single EDHs, DEDH should be considered more urgently for neurosurgical intervention.
