Introduction: Traumatic spine injuries are on the rise. The
literature is sparse regarding epidemiology of patients with traumatic spine injuries from this part of the world.
Objectives: To analyse the following in patients with
traumatic spine injuries with neurological deficits:
demographic and social profile, common modes of injury,
pre-hospitalisation practices, region of spine affected,
severity of neurological deficit and the lay individuals’
awareness about traumatic spine injuries. Methods: The
study sample comprised 52 adult patients with traumatic
spine injuries with neurological deficits. We collected data on demographic and social characteristics, mode of injury, pre-hospitalisation treatment, interval between injury and presentation, spine region affected and severity of neurological deficits and patient's knowledge about such injuries. Results: The average patient age was 31.32y. The male: female ratio was 2.25:1, and the most common modes of injury were fall from height, followed by traffic accident.
More than half of the patients suffered cervical spine
injuries, followed by dorsolumbar spine injuries. Only
9.61% of patients received pre-hospitalisation treatment. All patients understood there could be complete functional
recovery after treatment for traumatic spine injuries.
Conclusion: There is a growing need to improve railway and
roadway safety equipment and to make it accessible and
affordable to the susceptible economically weaker
population. Attempts should be made to increase awareness
regarding traumatic spine injuries.

Objective: To evaluate the fasting serum glucose (FSG) lowering potential of different fractions (C & D) and subfraction (D1 & D2) from aqueous extract of Aloe vera leaf on normal and alloxan induced type 2 diabetic rats. Methods: Two fractions (C & D) obtained by common chemical treatment of the aqueous extract of Aleo vera leaf and subfraction (D1 & D2) from fraction D were administered to the alloxan induced (150mg/kg i.p.) diabetic rats. The FSG lowering capacity, of different fractions and subfractions, was then evaluated in terms of percentage reduction in blood glucose level. Results: Oral administration of fractions C & D and subfraction D1 & D2 for 15 days led significant (P<0.05) reduction to the elevated FSG level of alloxan induced diabetic rats. Percentage reduction in blood glucose level and comparison with standard drug glibenclamide suggest the superiority of fraction D and subfraction D1 in hypoglycaemic potential. Conclusions:The results suggest that fraction D and subfraction D1 from aqueous extracts of Aloe vera leaf possesses the maximum FSG lowering capacity and further investigation is required for determination of anti-diabetic principal(s) and exact mechanism of their hypoglycaemic action.

BACKGROUND AND PURPOSE: Parkinson's disease (PD) and multiple-system atrophy of the parkinsonian type (MSA-P) are progressive neurodegenerative disorders that in addition to dysfunction of the motor system also present with features of dysautonomia, frequently manifesting as orthostatic hypotension (OH). The pathophysiology of OH has been proposed to differ between these two disorders. This study investigated the spontaneous and cardiovagal baroreflex sensitivity (BRS) in Parkinson's disease patients with orthostatic hypotension (PD(OH)) and multiple system atrophy of Parkinsonian type with orthostatic hypotension in an attempt to differentiate the two disorders. METHODS: Two methods were used for determining the BRS: a spontaneous method (spontaneous BRS) and the reflexive baroreflex gain (cardiovagal BRS) from phases II and IV of the Valsalva maneuver (VM) in PD(OH) and MSA-P(OH). RESULTS: The spontaneous BRS (5.04±0.66 ms/mm Hg vs. 4.78±0.64 ms/mm Hg, p=0.54) and the cardiovagal BRS from phase II of the VM (0.96±0.75 ms/mm Hg vs. 1.34±1.51 ms/mm Hg, p=0.76) did not differ between PD(OH) and MSA-P(OH), but the cardiovagal BRS from phase IV of the VM (0.03±0.07 ms/mm Hg vs. 2.86±2.39 ms/mm Hg, p=0.004) was significantly lower in PD(OH). CONCLUSIONS: The cardiovagal BRS from phase IV of the VM has potential for differentiating PD(OH) and MSA-P(OH), indicating a difference in the pathophysiological mechanisms underlying the autonomic dysfunction in the two disorders.

Bilateral distal anterior cerebral artery (DACA) aneurysms also called “kissing aneurysms” or “mirror aneurysm” are extremely rare, accounting for only 0.2% of all intracranial aneurysms. There have only been a few examples of mirror DACA aneurysms reported in the literature. Here, we report a rare case of mirror DACA aneurysm in a middle aged female with its successful clipping. Patient was admitted with severe headache and altered sensorium. Computed tomography (CT) head was suggestive of anterior inter-hemispheric hematoma. Digital subtraction angiography (DSA) was done which was suggestive of two distal anterior cerebral artery aneurysms located at same anatomical position. It was treated through microsurgical clipping. Mirror image DACA aneurysms are rare occurrence. All patients with ruptured DACA aneurysms should have angiography with 3D reconstruction studies. This aids in determining the aneurysm’s morphology and planning treatment accordingly.

Follicular variant of papillary carcinoma thyroid is an aggressive variant of papillary carcinoma thyroid. It is more commonly associated with extrathyroidal extension and regional lymphadenopathy. It can rarely be associated with microscopic vascular invasion but tumor thrombus into great veins is a rare phenomenon. We present a case of 60-year-old male with follicular variant of papillary carcinoma thyroid with tumor thrombosis in superior thyroid vein and internal jugular vein (IJV). We report a case of a 60-year-old male who presented with a large swelling in the lower part of left side of neck for 4 months. Clinical examination revealed a hard swelling of 12x8 cm in left side of neck. Ultrasonography showed a solitary thyroid mass of the left lobe and a dilated left superior thyroid vein and ipsilateral IJV. Fine-needle aspiration cytology revealed follicular variant of PTC cells. Total thyroidectomy was done. A tumor thrombus was discovered in the superior thyroid vein and left IJV was found to be dilated. The left IJV with superior thyroid vein was ligated and excised. The patient recovered well after the operation with no local or distant metastasis detected. Follicular variant of PTC commonly spreads to the lymph nodes. Vascular spread via direct intravascular extension through superior thyroid vein is extremely rare. On palpation cord like IJV is felt on the involved side. Neck ultrasound play important role in the diagnosis. Aggressive surgical treatment with IJV ligation above and below the tumor thrombus is recommended to minimize the risk of potentially fatal complications of the intraluminal masses. Intravascular tumor extension into IJV of neck in follicular variant of PTC is rare and can be associated with serious consequences. Total thyroidectomy with thrombectomy with ligation of IJV must be done.

Purpose:
Intracranial mycotic aneurysms (IMAs), rare and often life-threatening, result from arterial wall infections typically caused by bacteria such as Staphylococcus and Streptococcus. The standard treatment for ruptured aneurysms is not well-defined and often individualized. This study investigates the efficacy of endovascular glue embolization in managing ruptured IMAs, based on our center’s experience.
Materials and Methods:
A retrospective analysis was conducted for ruptured IMAs treated with glue embolization between January 2016 and December 2023. The procedure involved aneurysm sac and parent vessel occlusion with glue delivery. Data included patient demographics, clinical presentations, and neuroimaging. Clinical outcomes were assessed using the modified Rankin scale (mRS) at 3 months, and angiographic follow-up was conducted at 6 months.
Results:
The study included 28 patients, predominantly male (64.3%), with a mean age of 48 years. Headache was the primary symptom in 92.9% of cases, and positive blood/cerebro spinal fluid cultures were found in 82.14% of cases. All aneurysms were located in the distal circulation, primarily in the anterior circulation system. Glue embolization was successfully performed in all cases, achieving complete aneurysm sac and parent vessel obliteration. Follow-up at 3 months indicated mRS scores of 0 or 1 in 96.5% of cases. Six-month angiographic follow-up showed no aneurysm regrowth or new formations.
Conclusion
Endovascular glue embolization demonstrated high efficacy and safety in treating ruptured IMAs, with a 100% obliteration rate and favorable clinical outcomes in this single-center experience. Despite limitations such as its retrospective design and small sample size, the study supports glue embolization as a viable, less invasive alternative to traditional surgery. Further comparative studies are needed to confirm these findings and refine treatment approaches.
