The aim of this paper was to define an unexplained non-classified polyneuropathy condition as a new neurological disease. This new diagnosis of occupation related polyneuropathy has been named as “WORKING HAND SYNDROME (WHS).” This study collected and compared clinic and electrophysiological analyze data from healthy controls, WHS patients, carpal tunnel syndrome (CTS) patients and polyneuropathy patients. The WHS patients presented to the clinic with pain, numbness, tingling, and burning sensations in their hands that increased significantly during rest and nighttime. However, there was no weakness in the muscles, and the deep tendon reflexes were normal in this disease. The patients had all been working in physically demanding jobs requiring the use of their hands/arms for at least 1 year, but no vibrating tools were used by the patients. All of the cases were men. I supposed that overload caused by an action repeated chronically by the hand/arm may impair the sensory nerves in mentioned hand/arm. In patients with these complaints, for a definitive diagnosis, similar diseases must be excluded. Nonetheless, the specific electrophysiological finding that the sural nerves are normal on the lower sides, as well as the occurrence of sensory axonal polyneuropathy in the sensory nerves without a significant effect on velocity and latency in the work-ups of the upper extremity are enough to make a diagnosis. In conclusion, WHS has been defined as a polyneuropathy and occupational disease. Patients with WHS present with pain, numbness, tingling, and burning sensations in their hands that increases significantly during rest and nighttime. They also use their arms/hands for jobs that require heavy labor. The neurological examinations of patients with WHS are normal. Only the sensory nerves in the upper extremities are affected. This article is suggested to serve as a resource for patients, health care professionals, and members of the neurology community at large.

Background/Objectives: Takayasu arteritis is an important non-atherosclerotic cause of ischemic stroke in young adults. However, the relative contribution of systemic inflammation, inherited thrombophilia, and supra-aortic hemodynamic impairment to cerebrovascular events in these patients remains insufficiently defined. This study aimed to evaluate the relative impact of systemic inflammatory activity, hereditary and acquired thrombophilia markers, and supra-aortic vascular involvement on cerebrovascular ischemic events in patients with digital subtraction angiography (DSA) confirmed supra-aortic Takayasu arteritis. Methods: A retrospective cross-sectional analysis was conducted in consecutively evaluated patients with non-atherosclerotic inflammatory stenosis or occlusion of the carotid, subclavian, or vertebral arteries confirmed by digital subtraction angiography. Age- and sex-matched hospital-based individuals without autoimmune, thrombotic, or cerebrovascular diseases served as controls. Laboratory assessments including erythrocyte sedimentation rate, lipoprotein(a), homocysteine, antinuclear antibody, rheumatoid factor, antiphospholipid antibodies, and a hereditary thrombophilia panel were obtained 4–6 weeks after clinical presentation during a stable clinical phase. Results: Among 46 patients with Takayasu arteritis, 21 patients presented with ischemic stroke. The stroke-positive subgroup demonstrated higher inflammatory activity and a slightly greater prevalence of supra-aortic occlusive lesions, particularly involving the common carotid, internal carotid, and subclavian arteries. Although lipoprotein(a) levels showed statistical differences between groups, mean values remained within reference ranges and were not clinically elevated. The distribution of hereditary thrombophilia variants and the prevalence of elevated homocysteine levels did not differ significantly between groups. Clinical outcomes were favorable overall, with no mortality and functional independence achieved in the majority of stroke-positive patients. Conclusions: These findings suggest that systemic inflammation and supra-aortic hemodynamic impairment may play a more prominent role than inherited thrombophilia in the development of cerebrovascular ischemic events in patients with Takayasu arteritis. Selective rather than routine thrombophilia testing may therefore be appropriate in selected clinical contexts, while careful control of inflammatory activity and continuous vascular monitoring remain essential components of management.

Introduction: Endovascular treatment (ET) is a beneficial treatment for M1–2 occlusions of the middle cerebral artery. Mortality and disability rates are high if large vessel occlusions are not treated. While these rates are lower in M3 occlusions, important branch blockages can lead to disability. Endovascular treatment of small vessel occlusions is difficult, and there are no studies on the effectiveness of endovascular treatment for M3 occlusions. Accordingly, in this study, our aim was to assess the feasibility, safety, and preliminary efficacy of endovascular therapy for M3 occlusions. Methods: This study involved a retrospective analysis of a prospectively collected from two centres for acute ischemic stroke of the anterior system between July 2015 and April 2020. Demographic, radiologic, procedural and outcome variables were collected for patients who underwent endovascular therapy for acute ischemic stroke of the anterior system. Results: Complete or near complete reperfusion (mTICI 2b-3) of the M3 occlusion was achieved in 15 cases (38.5%). Complete (mTICI 3) reperfusion was achieved in 24 cases (61.5%). Twenty-six patients were treated for primary M3 occlusion, while 13 patients with M3 occlusion were treated as a rescue strategy after successful treatment of a proximal greater vascular occlusion. Complete or near complete reperfusion (mTICI 2b-3) of primary occlusion was achieved in eight cases (30.8%), and complete (mTICI 3) reperfusion was achieved in 18 cases (69.2%). In addition, complete or near complete reperfusion (mTICI 2b-3) of rescue M3 occlusion was achieved in seven cases (%53.8), while complete (mTICI 3) reperfusion was achieved in six cases (46.2%). Only one patient with primary M3 occlusion had ICH due to extravasation. The patient's neurological examination one month later was normal. Conclusions: This retrospective study demonstrates that endovascular treatment of M3 occlusions is safe, effective and reliable.

Mild encephalopathy with reversible splenial lesion (MERS) is characterized with a reversible lesion in the splenium of the corpus callosum. It has been defined as a neuro-radiologic syndrome associated with viral infections. In addition, this lesion may related with epileptic seizures, antiepileptic drugs or metabolic disturbances. We presented a patient with MERS associated with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2). Encephalopathy and psychiatric symptoms were the major initial clinical symptoms. Brain magnetic resonance imaging showed complete resolution of the corpus callosum lesion. The symptoms of patient recovered completely. Complete resolution of corpus callosum lesion and recovery of encephalopathy associated with SARS-COV-2 were similar to previous cases.
