OBJECTIVE: The vision of bioelectronic medicine is to treat disease by modulating the signaling of visceral nerves near various end organs. In small animal models, the nerves of interest can have small diameters and limited surgical access. New high-resolution methods for building nerve interfaces are desirable. In this study, we present a novel nerve interface and demonstrate its use for stimulation and recording in small nerves. APPROACH: We design and fabricate micro-scale electrode-laden nanoclips capable of interfacing with nerves as small as 50 µm in diameter...

Endoscopic or minimally invasive surgery popular as keyhole surgery is a medical procedure in which endoscope (a camera) is used, and it has gained broad acceptance with popularity in several surgical specialties and has heightened the standard of care. Oral and maxillofacial surgery is a modern discipline in the field of dentistry in which endoscopy has developed as well as widely used in surgeries and is rapidly gaining importance. The use of different visual as well as standard instruments such as laparoscopic and endoscopic instruments, and high-powered magnification devices, has allowed physicians to decrease the morbidity of many surgical procedures by eliminating the need for a large surgical incision...

OBJECTIVE: Patients suffering from pituitary adenomas may experience cognitive dysfunctions due to hormonal imbalance or suprasellar tumor extension displacing neural structures. Progressively enlarging or symptomatic nonfunctioning pituitary adenomas with suprasellar extension are frequently resected. The literature on neurocognitive performance surrounding resection of these lesions is sparse. METHODS: A prospective matched-control study was conducted to investigate the impact of nonfunctioning pituitary adenomas with suprasellar extension on preoperative and postoperative cognitive performance...

Minimally invasive surgery is rapidly becoming the norm in medicine, as it often leads to better outcomes and earlier rehabilitation. This article reviews the principles and different techniques employed to perform minimally invasive strabismus surgery (MISS). In these techniques, strabismus surgery is performed through keyhole openings, thus reducing the risk of postoperative corneal complications, minimizing postoperative discomfort, and better preserving muscle function. MISS can be used to perform all types of strabismus surgery, namely rectus muscle recessions, resections, plications, reoperations, retroequatorial myopexy, transpositions, oblique muscle recessions, or plications even in the presence of limited motility...

Breast implants are frequently encountered on breast imaging studies, and it is essential for any radiologist interpreting these studies to be able to correctly assess implant integrity. Ruptures of silicone gel-filled implants often occur without becoming clinically obvious and are incidentally detected at imaging. Early diagnosis of implant rupture is important because surgical removal of extracapsular silicone in the breast parenchyma and lymphatics is difficult. Conversely, misdiagnosis of rupture may prompt a patient to undergo unnecessary additional surgery to remove the implant...

The technique we describe was developed for cervical foraminal stenosis for cases in which a keyhole foraminotomy would not be effective. Many cervical stenosis cases are so severe that keyhole foraminotomy is not successful. However, the technique outlined in this study provides adequate enlargement of an entire cervical foraminal diameter. This study reports on a novel foraminal expansion technique. Linear drilling was performed in the middle of the facet joint. A small bone graft was placed between the divided lateral masses after distraction...
