Squamous cell carcinoma (SCC) of the tongue is the most common oral cancer. Because of the tongue’s frequent movement, abundant lymphatic drainage, and rich blood supply, the SCC is prone to regional lymph nodes and distant metastases, and its prognosis is worse than that of the other oral cancers.1 In addition, because of its special location, it and its secondary tissue defect postperatively may impair the patient’s pronunciation and swallowing. Reliable and stable therapeutic targets can improve...
The aim of this retrospective cohort study was to evaluate the relative amount of cancellous bone in the mandibular ramus as a predictor of lingual fracture patterns after bilateral sagittal split osteotomy (BSSO). The study including 78 consecutive patients (156 osteotomy sites). In preoperative cone-beam computed tomographic (CT) scans, the volumes of cancellous and cortical bone in the BSSO surgical field were estimated. Patients were divided into two groups based on the cortico:cancellous bone...
When I read the method of the above paper in detail it seemed likely that the ASIS would be included for <9cm and >9cm bone lengths as described by Taylor1 although this was not clearly stated. As a result I was not surprised that the pain score for longer defects was higher (6.71 v 4.64, p value not included, Table 1), the time to walking (6.64 v 4.72 weeks p value 0.002, Table 2) longer, as well as abnormality of the donor site (very abnormal >9cm 13/27(48%) v <9cm 6/35(17%), Table...
Obstructive sleep apnoea syndrome (OSAS), which is characterised by repetitive episodes of pharyngeal collapse during sleep, is gaining much attention because of the important deleterious consequences it might have on the patient’s health. We therefore organised a retrospective longitudinal study to report the long-term follow-up of maxillomandibular advancement (MMA) as a treatment for OSAS. A total of 19 patients with severe OSAS was treated during the period 2007–2016. They were followed up six...

BACKGROUND AND PURPOSE:The massa intermedia is a normal midline transventricular thalamic connection. Massa intermedia aberrations are common in schizophrenia, Chiari II malformation, X-linked hydrocephalus, Cornelia de Lange syndrome, and diencephalic-mesencephalic junction dysplasia, among others. We have noticed that massa intermedia abnormalities often accompany other midline malformations. The massa intermedia has never been formally evaluated in a group of exclusively pediatric patients, to...
BACKGROUND AND PURPOSE:Endovascular embolization only has been advocated for treatment of brain arteriovenous malformations in recent trials. Our aim was to evaluate the results of embolization only in a cohort of patients who were enrolled in the A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA) study at 39 clinical sites in 9 countries.MATERIALS AND METHODS:We analyzed the rates and severity of stroke and death in patients who underwent embolization only. Events were identified...
BACKGROUND AND PURPOSE:The natural history and optimal treatment of extracranial carotid artery aneurysms are unknown. Gadolinium enhancement of the aneurysm wall may reflect aneurysm wall inflammation and instability. In this study, we investigated the feasibility of extracranial carotid artery aneurysm wall imaging and explored a potential relationship of aneurysm wall enhancement with aneurysm growth and the presence of (silent) brain infarcts and white matter lesions.MATERIALS AND METHODS:Fourteen...
BACKGROUND AND PURPOSE:Conventional angiography is the criterion standard for measuring intracranial arterial stenosis. We evaluated signal intensity ratios from TOF-MRA as a measure of intracranial stenosis and infarct risk in pediatric stroke.MATERIALS AND METHODS:A retrospective study was undertaken in children with intracranial arterial stenosis, who had TOF-MRA and conventional angiography performed within 6 months. Arterial diameters were measured for percentage stenosis. ROI analysis on TOF-MRA...
BACKGROUND AND PURPOSE:Arterial spin-labeling-derived CBF values may be affected by arterial transit time artefacts. Thus, our aim was to assess to what extent arterial spin-labeling–derived CBF and cerebrovascular reserve capacity values in major vascular regions are overestimated due to the arterial transit time artifacts in patients with Moyamoya disease.MATERIALS AND METHODS:Eight patients with Moyamoya disease were included before or after revascularization surgery. CBF maps were acquired using...

Abstract Background The standard of care for CNS lymphoma typically includes high dose methotrexate followed by whole brain radiation therapy, but there is an increased risk of neurotoxicity with this regimen. In our institution, we offered stereotactic radiosurgery (SRS) for disease refractory to HD-MTX in a subset of patients. A search of the literature on this modality for CNS lymphoma was also conducted. ...
Abstract Purpose Immunotherapy, activation of the immune system to target tumor cells, represents a paradigm shift in the treatment of cancer. Immune checkpoint therapies, which target immunomodulatory molecules expressed on T-lymphocytes, have demonstrated improved survival in a variety of malignancies. However, benefit in glioblastoma, the most common and devastating malignant brain tumor, remains to be seen. With several recent clinical...

CRISPR-Cas9 gene editing provides a powerful tool to enhance the natural ability of human T cells to fight cancer. We report a first-in-human phase 1 clinical trial to test the safety and feasibility of multiplex CRISPR-Cas9 editing to engineer T cells in three patients with refractory cancer. Two genes encoding the endogenous T cell receptor (TCR) chains, TCRα (TRAC) and TCRβ (TRBC), were deleted in T cells to reduce TCR mispairing and to enhance the expression of a synthetic, cancer-specific TCR...
The New Horizons spacecraft’s encounter with the cold classical Kuiper Belt object (486958) Arrokoth (provisional designation 2014 MU69) revealed a contact-binary planetesimal. We investigated how Arrokoth formed and found that it is the product of a gentle, low-speed merger in the early Solar System. Its two lenticular lobes suggest low-velocity accumulation of numerous smaller planetesimals within a gravitationally collapsing cloud of solid particles. The geometric alignment of the lobes indicates...
