Background: Tuberculous meningitis (TBM) remains to be one of the most fatal central nervous system infections. The exact pathogenesis of TBM at cellular level remains unclear. In this study, we assessed the cytokine levels in the serum and cerebrospinal fluid (CSF) of TBM patients and determined their correlation with the disease activity. Methods: The levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were measured by enzyme linked immunosorbant assay (ELISA) in both serum and CSF of 38 patients at baseline, and in 17 of these patients at 1 and 6 month of follow-up. Clinical examination and imaging was performed at baseline and on follow-ups. Results: There was a remarkable rise in the levels of serum and CSF TNF-α and IL-1β in TBM patients as compared to age and sex matched controls (p<0.05). A significant correlation was found between cytokine levels and stages of TBM (p< 0.05). TNF-α levels in both serum and CSF and IL-1β levels in serum were found to be significantly higher in those patients who died than those who survived and had better outcome. TNF-α was higher in patients who developed tuberculoma on follow-up than those who did not (p<0.05). The cytokine levels progressively declined over time but remained detectable till 6 months in most patients. Conclusions: The higher levels of TNF-α and IL-1β were associated with poor outcome in TBM. The higher cytokine levels in patients developing tuberculoma on antituberculous therapy and steroids suggests that these patients may benefit from immunomodulation agents like anti-TNF-α antibody.

BACKGROUND: Modified radical mastectomy is associated with appreciable blood loss, while endotracheal intubation leads to elevated hemodynamic responses. The present study aimed to evaluate the clinical efficacy of dexmedetomidine infusion as an anesthetic adjuvant to general anesthesia during modified radical mastectomy with I-Gel. METHODS: Sixty adult consenting female patients, of American Society of Anesthesiologists physical status 1 to 2 and aged 4,065 years, were blindly randomized into two groups of 30 patients each. The patients in Group I received intravenous dexmedetomidine at a loading dose of 1 µg/kg over 10 min, followed by maintenance infusion of 0.4 to 0.7 µg/kg/h, while patients in Group II were administered an identical amount of saline infusion until 15 min prior to the end of surgery. The primary end point was bleeding at the surgical field and hemodynamic changes; requirement of isoflurane, intraoperative fentanyl consumption and recovery time were assessed as secondary outcomes. RESULTS: The patients receiving dexmedetomidine infusion showed significantly less bleeding at the surgical field (P < 0.05). A statistically significant reduction was also observed in the percentage of isoflurane required (0.82 ± 0.80%) to maintain the systolic blood pressure between 100 and 110 mmHg in patients receiving dexmedetomidine infusion compared with the Group II (1.50 ± 0.90%). The mean intraoperative fentanyl consumption in patients in the Group I was also significantly lower compared with that of the Group II (38.43 ± 5.40 µg vs. 75.12 ± 4.60 µg). The mean recovery time from anesthesia did not show any clinically significant difference between the groups. CONCLUSIONS: Dexmedetomidine infusion can be used safely to decrease the bleeding at the surgical field with smooth recovery from anesthesia.

A 35 years old female presented to us after falling from a height. She complained of a neck pain and a complete quadriplegia and was diagnosed as having spondyloptosis of the C6-C7. Skeletal traction was performed on her. CT scan showed fractures of the C5, C6, and C7 vertebral body. The patient underwent anterior approach partial corpectomy with anterior cervical locking plate and strut grafting from ipsilateral iliac crest. Intraoperatively it was found that the disc was completely ruptured and there was a dural tear and cerebrospinal fluid leak. Her postoperative period was complicated by cerebrospinal fluid collection and posterior instrumentation was not performed due to the poor general condition. She had no neural recovery at the last follow-up. Spondyloptosis is a severe and highly unstable injury with a three column ligamentous disruption and may be complicated, as in our case, with a dural tear. Management of these cases is fraught with complications, and prognosis for neural recovery is dismal.

Epithelioid inflammatory myofibroblastic sarcoma (EIMS) is an aggressive subtype of inflammatory myofibroblastic tumor (IMT) harboring anaplastic lymphoma kinase (ALK) gene fusions and is associated with high risk of local recurrence and poor prognosis. Herein, we present a young, non-smoking male who presented with complaints of cough and dyspnoea and was found to harbor a large right lower lobe lung mass. Biopsy showed a high-grade epithelioid to rhabdoid tumor with ALK and desmin protein expression. The patient initially received 5 cycles of crizotinib and remained stable for 1 year; however, he then developed multiple bony metastases, for which complete surgical resection was performed. Histopathology confirmed the diagnosis of EIMS, with ALK gene rearrangement demonstrated by fluorescence in situ hybridization. Postoperatively, the patient is asymptomatic with stable metastatic disease on crizotinib and has been started on palliative radiotherapy. EIMS is a very rare subtype of IMT that needs to be included in the differential diagnosis of ALKexpressing lung malignancies in young adults.

Snakebite is a severe medical, economic, and social problem across the world, mostly in the tropical and subtropical area. These regions of the globe have typical of the world's venomous snakes present where access to prompt treatment is limited or not available. Snake venom is a complex mixture of toxin proteins like neurotoxin and cardiotoxin, and other enzymes like phospholipase A2 (PLA2 ), haemorrhaging, transaminase, hyaluronidase, phosphodiesterase, acetylcholinesterase, cytolytic and necrotic toxins. Snake venom shows a wide range of biological effects like anticoagulation or platelet aggregation, hemolysis, hypotension and edema.Phospholipase A2 is the principal constituent of snake venom; it catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to liberate arachidonic acid, which is the precursor of eicosanoids including prostaglandins and leukotrienes. The information regarding the structure and function of the phospholipase A2enzyme may help in treating the snakebite victims. This review article constitutes a brief description of the structure, types, mechanism occurrence, and tests of phospholipase A 2 and role of components of medicinal plants used to inhibit phospholipase A2 .

Multiple intracranial cavernomas are rare and occur mostly in familial cases. Clinical presentation with simultaneous rupture of two or more lesions has only been reported in four cases to date. A 15-year-old boy presented with simultaneous right frontal and superior vermian hematomas with hydrocephalus. The patient underwent a ventriculoperitoneal shunt, and his magnetic resonance imaging (MRI) revealed multiple cavernomas with bleed in the above-mentioned locations. The patient underwent a midline suboccipital craniotomy and excision of the cavernoma. The supratentorial lesions were left in situ in lieu of small size, no history of seizures, mass effect, or other neurological deficits. The patient recovered well from surgery with significant improvement in truncal ataxia. He remained asymptomatic for supratentorial lesions at follow-up. Cavernomas should be considered as differential diagnoses in cases of multiple intraparenchymal hemorrhages, especially in pediatric patients. The surgical management should be rationalized based on the lesion location, the eloquence of the surrounding parenchyma, mass effect, and the risks of re-rupture. Due to the rarity of multiple simultaneous hemorrhages, the management of multiple cavernomas remains controversial. The patient’s relatives can be screened with MRI to rule out the familial form of the disease. Strict clinical and radiological follow-up is a must in such patients.

STUDY DESIGN: Retrospective radiological study. PURPOSE: We aimed to determine the prevalence of ponticulus posticus (PP) and high-riding vertebral artery (HRVA) occurring simultaneously on the same side (PP+HRVA) and in cases of PP+HRVA, to assess C2 radio-anatomical measurements for C2 pars length, pedicle width, and laminar thickness. OVERVIEW OF LITERATURE: PP and HRVA predispose individuals to vertebral artery injuries during atlantoaxial fixation. In cases of PP+HRVA, the construct options thus become limited. METHODS: Consecutive computed tomography scans (n=210) were reviewed for PP and HRVA (defined as an internal height of <2 mm and an isthmus height of <5 mm). In scans with PP+HRVA, we measured the ipsilateral pedicle width, pars length, and laminar thickness and compared them with controls (those without PP or HRVA). RESULTS: PP was present in 14.76% and HRVA in 20% of scans. Of the 420 sides in 210 scans, PP+HRVA was present on 13 sides (seven right and six left). In scans with PP+HRVA, the C2 pars length was shorter compared with controls (13.69 mm in PP+HRVA vs. 20.65 mm in controls, p<0.001). The mean C2 pedicle width was 2.53 mm in scans with PP+HRVA vs. 5.83 mm in controls (p<0.001). The mean laminar thickness was 4.92 and 5.48 mm in scans with PP+HRVA and controls, respectively (p=0.209). CONCLUSIONS: The prevalence of PP+HRVA was approximately 3% in the present study. Our data suggest that, in such situations, C2 pedicle width and pars length create important safety limitations for a proposed screw, whereas the translaminar thickness appears safe for a proposed screw.
