Intracranial angioplasty and stenting is an increasingly common modality to treat intracranial atherosclerosis, which accounts for 80 000 strokes annually. Early trials showed there to be a high complication rate1,2 associated with stenting but with improved technique this complication rate has dramatically decreased.3 The following video details the procedure of intracranial balloon angioplasty and stenting for a high-grade stenosis of the right internal carotid artery. The risks and benefits of the procedure were discussed with the patient and they consented to the procedure.Petrous meningiomas are defined as tumors with a basal dural attachment on the posterior surface of the petrous bone.1 Their insertion can be anterior to the meatus (petrous apex meningiomas), or posterior to the meatus, with associated hyperostotic bony invasion either pre- or retro-meatal.2 These meningiomas are amenable to curative surgical removal and have better surgical outcomes than more medially located true petroclival meningiomas that originate medial to the fifth nerve.2-4 They, however, remain challenging because of their close relationship to critical neurovascular structures in the cerebellopontine angle.5 The posterior petrous meningiomas might reach a significant size with compression of the cerebellum, the brainstem, and involvement of the cranial nerves, and extend posteriorly to the transverse sigmoid sinus.2,6  Transmastoid approach with skeletonization and lateral reflection of the transverse sigmoid sinus provides a superb exposure without cerebellar retraction.6,7 The ease and complete resection of the tumor and invaded bone can be facilitated by combined microscopic-endoscopic techniques. We demonstrate these principles through the resection of a petrosal meningioma in a 56-yr-patient who presented with headaches, nystagmus, and mild cerebellar signs. The patient consented to the procedure.  Image at 136 reprinted with permission from Al-Mefty O, Operative Atlas of Meningiomas. Vol 1, ©LWW, 1998.
Both fructose consumption and chronic stress contribute to the development of metabolic disorders. The consequences of such combination are not fully understood.

We investigated whether fructose supplementation and chronic stress synergistically disturb hepatic lipid and glucose metabolism. The role of energy sensing, redox, and inflammatory status during development of metabolic disturbances was investigated.

Female Wistar rats, aged 2.5 mo, were divided into 4 experimental groups control (C) fed a standard diet (commercial food and drinking water); fructose (F) fed the same food and 10% fructose solution; stress (S) fed the standard diet and subjected to chronic unpredictable stress and, stress+fructose (SF) combining conditions F and S as above. Stress included daily stressors cold water forced swimming, physical restraint, cold room, wet bedding, rocking, switching, or tilting cages. After 9 wk, hepatic enzymes and transcription factors involved in gluconeogenesis, lipogenesis, fatty acid oxidation,patic lipid accumulation and inflammation, suggesting that, in female rats, AMPK activation prevails over stress-induced effects.
Fructose does not enhance stress effects on hepatic lipid and glucose metabolism but attenuates its effects on hepatic lipid accumulation and inflammation, suggesting that, in female rats, AMPK activation prevails over stress-induced effects.Chondrosarcomas are a spectrum of tumors with variable clinical behavior, histologically classified as grades I, II, and III.1 Maximal surgical resection with adjuvant radiation is the gold standard for grade III malignant tumors.2,3 Lower-grade skull base chondrosarcomas have a slow progressive local growth pattern with an overall benign profile.1,4 In these grade I and II tumors, radical resection can be sufficient in achieving long-term control of the disease without the need for adjuvant therapy, thus avoiding the long-term side effects of irradiation in relatively young patients.4,5 As a slow-growing tumor, skull base chondrosarcoma might reach a giant size with progressive neurological deficits prior to diagnosis. In these cases, to achieve maximal resection, skull base approaches tailored to the patient's anatomy are essential.4,6 Cranial approach is frequently needed due to the calcified nature of part of the tumor that is not amenable to resection through the endonasal approach. The endoscope is extremely helpful combined with the microscopic resection. We demonstrate these techniques through in the surgery of a 39-yr-old female who presented with progressive neurological deficits from a giant ossified chondrosarcoma and underwent a combined petrosal approach for the resection of her tumor. A postoperative small enhancement remained stable on the 4-yr follow-up exam. The pathology confirmed grade II chondrosarcoma, with the patient recovering from her neurological deficit except the third nerve. The patient consented to the surgery and publication of images.  Image at 136 reprinted with permission from Al-Mefty O, Operative Atlas of Meningiomas. Vol 1, ©LWW, 1998.
Low back pain (LBP) is a major cause of visits to ambulatory care, missed duty time, and disability discharge. The subacute phase of LBP presents an opportune time to prevent chronicity and lessen recurrence. The goal of this randomized controlled trial (RCT) was to determine the relative effectiveness of neuromuscular electrical stimulation (NMES) training and a progressive exercise program (PEP) on improving physical performance, pain, and torso strength in U.S. service members with subacute LBP, compared to standard primary care management (PCM) alone.

This is an Institutional Review Board-approved protocol for an RCT conducted with active duty military personnel (n = 128) at Fort Campbell, Kentucky, between April 2018 and March 2020. Participants were randomized to receive NMES (n = 43), PEP (n = 42), or PCM (n = 43) for 9 weeks. Outcome measures of physical performance (sit-ups, push-ups, walking, and torso endurance), torso muscle strength (flexion and extension), and pain were assessed at baseline r a modest benefit for increasing sit-ups and push-ups and improving torso strength.
In an active duty population with subacute LBP, integrating NMES strength training into the rehabilitation therapy may offer a modest benefit for increasing sit-ups and push-ups and improving torso strength.
Angelman syndrome (AS) patients often respond to low glycemic index therapy to manage refractory seizures. These diets significantly affect quality of life and are challenging to implement. These formulations may have benefits in AS even in the absence of biomarkers suggesting ketosis.

We aimed to compare an exogenous medical food ketone formulation (KF) with placebo for the dietary management of AS.

This randomized, double-blind, placebo-controlled, crossover clinical trial was conducted in an academic center from 15 November, 2018 to 6 January, 2020. Thirteen participants with molecularly confirmed AS aged 4-11 y met the criteria and completed the 16-wk study. The study consisted of four 4-wk phases a baseline phase, a blinded KF or placebo phase, a washout phase, and the crossover phase with alternate blinded KF or placebo. Primary outcomes were safety and tolerability rated by retention in the study and adherence to the formulation. Additional secondary outcomes of safety in this nonverbal populatioous KF appears safe. More data are needed to determine the utility of exogenous ketones as a nutritional approach in children with AS.This trial was registered at clinicaltrials.gov as NCT03644693.Surgical resection is one option in the treatment of large high-grade brain arteriovenous malformations (AVMs). Resection of AVMs with skull-eroding components can be challenging due to the risk of excessive bleeding from these components during craniotomy and bone flap removal. We present a case of a 25-yr-old woman who presented with an acute onset right-sided frontal headache. She was found to have a large, frontal Spetzler-Martin grade IV AVM with an associated dural AVM. Brusatol inhibitor The AVM had caused focal erosions of the right frontal bone by a venous varix traversing the region of the calvarial defect. An elective staged endovascular embolization followed by surgical resection was recommended considering the patient's young age and the large size of the AVM located in a noneloquent area. Given the high risk of intraoperative hemorrhage during the craniotomy portion of the procedure, a "craniotomy within craniotomy" approach was planned. During this approach, a small rectangle of bone, including the portion eroded by the venous varix, was left in place, while the larger bone flap surrounding it was removed for an initial approach to the AVM. The small bony piece was safely removed at later stages of resection once the arterial feeders had been reasonably obliterated. Immediate postoperative catheter angiogram demonstrated good filling of the intracranial vascular territories with no residual AVM. The patient developed mild left facial and left hand weakness postoperatively, which resolved after 2 wk of follow-up. The patient remained neurologically intact on further follow-up.Ruptured cerebral aneurysm is a grave disease, with a high morbidity and mortality, mandating securing the aneurysm to eliminate fatal rebleeding.1 Multiple aneurysms are frequent and may occur in approximately 20% of the cases with female prominence.2 The risk of subarachnoid hemorrhage in unruptured aneurysms is higher in patients who had prior ruptured aneurysms.3 Hence, there is an indication of treating all concomitant aneurysms when one is ruptured. We present the case of clipping of 3 aneurysms via a cranioobritozygomatic (COZ) approach including a middle cerebral artery, anterior choroidal artery, and superior cerebellar artery in a patient presenting with subarachnoid hemorrhage and multiple aneurysms with suboptimal morphology for endovascular coiling. We highlight the advantages of the COZ in the clipping of complex posterior circulation aneurysms and the advantage of mobilization of neural structures to gain wider exposure.4-6 The temporal fossa space provided by zygomatic osteotomy allows the outward mobilization of the temporal lobe after freeing it by splitting the Sylvian fissure. The falciform ligament is opened overlying the optic nerve, allowing for safe dissection within the opticocarotid window. The oculomotor nerve is detethered from the dura surrounding its entry into the cavernous sinus. These maneuvers allow for mobilization of the critical neurovascular structures, which widens the operative corridor without undue traction or retraction. The COZ with clinoidectomy shortens and widens the operative field, allows for enhanced maneuverability, improved visualization, and exposure of the clinoidal carotid, and facilitates the release and mobilization of the optic and third nerve. The patient consented to surgery.  Image at 140 reprinted with permission from Al-Mefty O, Operative Atlas of Meningiomas. Vol 1, © LWW, 1998.
MicroRNAs (miRNAs) are small noncoding RNAs involved in posttranscriptional regulation. miRNAs can be secreted and found in many body fluids, and although they are particularly abundant in breastmilk, their functions remain elusive. Human milk (HM) miRNAs start to raise considerable interest, but a comprehensive understanding of the repertoire and expression profiles along lactation has not been well characterized.

This study aimed to characterize the longitudinal profile of HM miRNA between the second week and third month postpartum.

We used a new sensitive technology to measure HM miRNAs in a cohort of 44 French mothers [mean ± SD age 31 ± 3.5; BMI (in kg/m2) 21.8 ± 2.3] who delivered at term and provided HM samples at 3 time points (17 ± 3 d, 60 ± 3 d, and 90 ± 3 d) during follow-up visits.

We detected 685 miRNAs, of which 35 showed a high and stable expression along the lactation period analyzed. We also described for the first time a set of 11 miRNAs with a dynamic expression profile. To gain insight into the potential functional relevance of this set of miRNAs, we selected miR-3126 and miR-3184 to treat undifferentiated Caco-2 human intestinal cells and then assessed differentially expressed genes and modulation of related biological pathways.
