The challenges and opportunities of global neurosurgery in East Africa: the Neurosurgery Education and Development model

Andreas Leidinger, Pablo Extremera, Eliana E. Kim, Mahmood M. Qureshi, Paul H. Young, and José Piquer

locations, equipment repair requires the intervention of out-sourced official providers that mostly fly in from Kenya and South Africa. The NEDF is constantly trying to reduce these delays by donating needed hardware and networking with different providers to repair broken equipment. Document and Information Administration Recently, the development of telecommunications in East Africa has allowed the massive diffusion of smartphones and tablets. In a context with limited access to desktop computers and storage, we recommend utilizing digital clouds for documents and

A wearable mixed-reality holographic computer for guiding external ventricular drain insertion at the bedside

valuable space, 1 , 6 image-guided methods are not routinely applied to assist in bedside EVD placement. To achieve a low-cost, portable approach, researchers have ingeniously adopted the concept of “augmented reality,” in which computer-generated images are superimposed on the user’s view, resulting in a composite view. With the use of smartphone software, a semitransparent 2D CT/MR image or reconstructed model can be overlaid on the live feed from the smartphone camera during the surgical procedure. By aiming the camera at corresponding surface landmarks in the

Approaches to closed-loop deep brain stimulation for movement disorders

between patients with PD in “on” and “off” medication states, and also between PD patients and healthy individuals. 8 Preliminary data on the use of smartphones to gather similar kinematic data show that symptom severity can be predicted for modalities, such as gait, 16 bradykinesia, 29 and dyskinesias. 53 Data of this type could potentially be used to provide a viable reference signal for adaptive DBS systems, using individual patient models of the disease state to modulate delivery of DBS. Electromyography Surface EMG (sEMG) from symptomatic extremities can

Beyond infrared and inductive-coupled magnetic tracking systems, groups have used fiberoptic endoscope technology and robotic assistance for catheter placement. 22 , 24 , 33 , 40 , 41 Thomale et al. have described a fixed-frame guidance system comprised of a rigid arc, catheter guide tube, and coordinates calculated with smartphone software analyzing an uploaded DICOM image. 42 To date, ultrasound-image assisted ventricular catheter placement has predominantly occurred in the intraoperative setting. 1 , 3 , 7 , 17 , 32 , 34 , 37–39 Early placement

An integrated risk model stratifying seizure risk following brain tumor resection among seizure-naive patients without antiepileptic prophylaxis

-up monitoring for evidence of seizure activity. In our simulation of long-term seizure risk stratification using a time-to-event approach, we identified a subset of patients with an elevated long-term risk for postdischarge seizures. These patients, compared with those predicted to be at lowest risk for seizures, were 6 and 13 times as likely to develop seizures and SE, respectively. Currently, ongoing efforts are exploring approaches for long-term seizure monitoring in the outpatient and home settings by employing technologies such as smartphone- and web-based applications

The effect of augmented reality on the accuracy and learning curve of external ventricular drain placement

Frederick Van Gestel, Taylor Frantz, Cédric Vannerom, Anouk Verhellen, Anthony G. Gallagher, Shirley A. Elprama, An Jacobs, Ronald Buyl, Michaël Bruneau, Bart Jansen, Jef Vandemeulebroucke, Thierry Scheerlinck, and Johnny Duerinck

IR tracking showed high accuracy (0.78 ± 0.74 mm) as well as less of a perceived drift compared with RGB tracking (Frantz et al., unpublished data). Others have reported on the use of more portable devices for AR assistance, such as tablets or smartphones. Although these devices allow higher mobility and flexibility than the classic neuronavigational systems, they also impede the surgeon from using both hands and can be affected by an important parallax error. 28 , 29 These problems are ameliorated by using an HMD, although physical discomfort can be experienced

Benefits of Enhanced Recovery After Surgery for fusion in degenerative spine surgery: impact on outcome, length of stay, and patient satisfaction

Bertrand Debono, Marco V. Corniola, Raphael Pietton, Pascal Sabatier, Olivier Hamel, and Enrico Tessitore

Postoperative Management With Dedicated Mobile App A dedicated mobile app (e-fitback, Nouveal e-santé) was used for the postoperative monitoring of patients in the post-ERAS group only. All consecutive patients had a smartphone, tablet, or personal computer ( Fig. 2 ). During the preoperative consultation with ERAS nurses, a Quick Response (QR) code was given free of charge to the patient to load the app on the platform of his or her choice and for connection from 48 hours prior to surgery until the 15th postoperative day. FIG. 2. Mobile app dedicated to patient home

Numerous attempts to improve the accuracy of EVD catheter targeting have been reported in the literature to date, including robotic, smartphone, neuronavigation, ultrasound, flat detector CT, and real-time fluoroscopy–assisted EVD placement, as well as using a mechanical guide device (the Ghajar guide). 3 , 14 – 18 While image guidance techniques have been demonstrated to improve EVD placement accuracy, 15 none of them have been widely introduced into clinical practice. Moreover, O’Neill et al. analyzed

diagnostic device, we feel encouraged that this software can provide accurate and meaningful diagnostic feedback for users. If incorporated into a smartphone application, this tool could allow families and providers questioning the severity of a child’s cranial deformity to simply acquire a set of orthogonally oriented photos of the child’s head and face, and the software could then provide CI (scaphocephaly, brachycephaly), CVAI (plagiocephaly), AAA (trigonocephaly), and TCLA (anterior congenital plagiocephaly) measurements that can be trended over time and interpreted
