Randomized Controlled Trial Comparative Study
Normal pressure hydrocephalus and parkinsonism: preliminary data on neurosurgical and neurological treatment.
Idiopathic normal pressure hydrocephalus (iNPH) may present, besides the classic triad of symptoms, with extrapyramidal parkinsonianlike movement disorders. We present a randomized prospective study comparing adjustable ventriculoperitoneal (VP) shunt insertion plus dopamine oral therapy (group A) versus VP shunt alone (group B) in patients affected by iNPH associated with parkinsonism. ⋯ iNPH associated with parkinsonism may be a frequent finding. In these cases, patients may benefit from VP shunt plus dopamine oral therapy.

Options for anticoagulation have been expanding constantly during the past few years, providing a greater number of agents for prevention and management of thromboembolic disease. Although heparins and vitamin K antagonists (VKAs) has been used extensively for many decades, their narrow therapeutic range, interactions with other medications and food, and the need for routine monitoring of blood levels have led to the search for less problematic alternatives. Direct oral anticoagulants represent an important advance in anticoagulation therapy, directly inhibiting thrombin (dabigatran) or factor Xa (rivaroxaban, apixaban) they represent an effective and safe alternatives to VKAs and heparins in the prevention and treatment of several thromboembolic disorders. ⋯ Reversal agents are approved for some and under development for others, concerns over the lack of antidotes or difficulty in obtaining them has tempered enthusiasm for their use because of the perception of better safety with heparins and VKAs as a result of the availability of effective reversal strategies. Appropriate use of these agents requires knowledge of their individual characteristics, mechanisms of action, pharmacokinetics, ways of monitoring, and when needed, manage patients in need of urgent surgery especially in life-threatening bleeds. This article provides a suggested comprehensive approach to manage patients with intracranial hemorrhage while on direct oral anticoagulants who require an urgent surgical intervention and who cannot wait for plasma concentration to decline.

This study compared the radiologic and clinical outcomes of kyphoplasty with intravertebral reduction device (IRD) and vertebroplasty (VP) in treating osteoporotic vertebral compression fractures (OVCFs). ⋯ Our findings reveal significantly more efficient height restoration and kyphosis correction and fewer refractures in the IRD group. IRD may not increase the risk of adjacent or nonadjacent fractures.

Prospective comparison of microsurgical, endoscopic, and endoscopically assisted discectomies: Clinical effectiveness and complications in railway workers.
Although endoscopic diskectomy is superior to microsurgical diskectomy in terms of incision size, postoperative pain, and cosmetic appeal, the effectiveness and indications for endoscopic versus microsurgical diskectomy remain active discussion topics. Because of the increasing incidence of diskectomies being performed in Russia, further assessment of these techniques is needed. We performed a comparative analysis of 1-year clinical results and complications of microsurgical, tubular-based interlaminar endoscopic, and endoscopically assisted microsurgical diskectomies for patients with herniated lumbar disks. ⋯ Our findings indicate that these 3 surgical techniques are highly effective and have similar clinical results at 1-year follow-up. Although this study points to differences in complications resulting from the 3 techniques, larger prospective studies are needed to more definitively assess possible surgical differences, complications, and outcomes. The endoscopically assisted diskectomy technique allows for minimally invasive surgery and offers enhanced visualization of the anatomy that is hidden from view in microscopic procedures.

En bloc resection of high-cervical chordomas is a technically challenging procedure associated with significant morbidity. Two key components of this procedure include the approach and the method of spinal reconstruction. A limited number of reported cases of en bloc resection of high-cervical chordomas have been reported in the literature. ⋯ Labiomandibular glossotomy for approach to high anterior cervical chordomas followed by craniospinal reconstruction to the clivus with an expandable cage represents a novel technique for managing high cervical chordomas.
