Snake Bite and Radiology

Discussion-Local manifestations of snake bite are soft-tissue swelling from edema, necrosis, and hemorrhage. Common long-term sequelae of envenomation is soft-tissue atrophy distal to the bite, particularly in the digits.-Systemic signs and symptoms after a venomous snake bite are due to anticoagulant/procoagulant activity or neurotoxicity. Cerebral hypoxia can occur due to hypotensive shock that may accompany some snake bite envenomations. Neuromuscular disorders with damage of the peripheral nervous system can with blockage of synaptic transmission, at either presynaptic or postsynaptic levels.Common neurological symptoms are ptosis , ophthalmoplegia, limb weakness , respiratory failure, palatal weakness and neck muscle weakness.Cerebrovascular complications are –-          ischaemic strokes in various arterial territories,-         haemorrhagic stroke including multiple lobar haemorrhages with or without ventricular extension,-          haemorrhages in subarachnoid and subdural spaces,-         cerebellar haemorrhage, epidural haematoma,-         optic neuritis,-          delayed cerebellar ataxia,-         disseminated enc...

This study aimed to evaluate the therapeutic effect of folic acid (FA) on diabetic retinopathy (DR) in a genetic mouse model of obese type 2 diabetes mellitus (T2D). C57BL/KsJ-db/db(db/db) T2D mice were divided into control, FA, metformin (MET), and FA plus MET groups (n = 10/group). Serum levels of glucose, glycated hemoglobin, and insulin were determined weekly. The retinal thickness was measured using optical coherence tomography (OCT) at 4 weeks after treatments. The retinal expression and serum levels of vascular formation, inflammation, and oxidative stress-associated molecules were examined. Our results demonstrated...

Conclusions: Eyes from diabetic patients in the initial stages of DR with different Early Treatment Diabetic Retinopathy Study gradings show similar prevalence of SCME and CIME, independent of the severity of the retinopathy. Retinal edema is located mainly in the INL and appears to be mostly extracellular except in the earliest stages of diabetic retinal disease where intracellular edema predominates.Ophthalmic Res

We describe a case of a 55-year-old man who presented with right internal carotid artery dissection and deviation to the left of the protruded tongue. The direction of the deviation of the protruded tongue was unexpected in this patient, because if the XII nerve palsy was due to mass effect related to the intramural hematoma of the dissected artery, a deviation to the right should have happened. Anyway, a subsequent magnetic resonance revealed also an acute ischemic lesion in the right tongue area in the primary motor cortex of the patient, providing a rare, but a fitting neuroanatomical explanation of the deviation and al...
