Notes

Order is important: the particular blended effects of classical fitness and oral suggestions upon placebo hypoalgesia and nocebo hyperalgesia.
Although the method requires prespecification of the risk window of interest and may miss some true signals detectable using the tree-temporal variant of the method, it allows for early detection of potential safety problems through early initiation of ongoing monitoring.
Technically and ergonomically correct positioning is essential in endoscopic transsphenoidal pituitary surgery.

To propose a safe, ergonomic approach to conduct endoscopic endonasal pituitary and skull base surgery in large patients without sacrificing important aspects of current standard practice.

The patient's right arm is outstretched and secured in a supine position, with the primary surgeon standing in the axillary area. Considerations include maintaining comfort, immobility, anesthesia access, endotracheal tube fixation, intravenous lines, thorax elevated 25° to 30° for optimization of respiration, free and exposed abdomen for fat graft, legs positioned with no sciatic stretch or venous strain, and the patient's head in parallel with the surrounding area to sustain a strict midline.

Ten patients who underwent transsphenoidal pituitary tumor resections conducted using the hitchhiker position from October 2019 to June 2021 comprised our study cohort. The patients' mean height was 168.70 ± 9.29 cm, their mean weight was 114.35 ± 19.32 kg, and their mean body mass index was 40.19 ± 6.39 kg/m 2 . Twenty percent (n = 2) patients had a body mass index classified as "obesity class 1," 50% (n = 5) as "obesity class 2," and 30% (n = 3) as "extreme obesity class 3." The primary surgeon consistently reported decreased bodily strain and improved ergonomic access to the surgical site using the hitchhiker position.

The hitchhiker position offers the opportunity to improve both patient and physician well-being in the context of endoscopic pituitary surgery.

Though the method has been used for several decades to track other infectious diseases, there has not been a comprehensive review outlining all of the pathogens that have been surveilled through wastewater. Herein we identify what infectious diseases have been previously studied via wastewater surveillance prior to the COVID-19 pandemic. Infectious diseases and pathogens were identified in 100 studies of wastewater surveillance across 38 countries, as well as themes of how wastewater surveillance and other measures of disease transmission were linked. Twenty-five separate pathogen families were identified in the included studies, with the majority of studies examining pathogens from the family Picornaviridae, including polio and non-polio enteroviruses. Most studies of wastewater surveillance did not link what was found in the wastewater to other measures of disease transmission. Among those studies that did, the value reported varied by study. Wastewater surveillance should be considered as a potential tool for many infectious diseases. Wastewater surveillance studies can be improved by incorporating other measures of disease transmission at the population-level including disease incidence and hospitalizations.There is great interest in developing non-invasive approaches for studying cortical plasticity in humans. High-frequency presentation of auditory and visual stimuli, or sensory tetanisation, can induce long-term-potentiation-like (LTP-like) changes in cortical activity. However, contrasting effects across studies suggest that sensory tetanisation may be unreliable. We review these contrasting effects, conduct our own study of auditory and visual tetanisation, and perform meta-analyses to determine the average effect of sensory tetanisation across studies. We measured auditory-evoked amplitude changes in a group of younger (18-29 years of age) and older (55-83 years of age) adults following tetanisation to 1 and 4 kHz tone bursts and following a slow-presentation control. We also measured visual-evoked amplitude changes following tetanisation to horizontal and vertical sign gradients. Auditory and visual response amplitudes decreased following tetanisation, consistent with some studies but contrasting with others finding amplitude increases (i.e. LTP-like changes). Older adults exhibited more modest auditory-evoked amplitude decreases, but visual-evoked amplitude decreases like those of younger adults. Changes in response amplitude were not specific to tetanised stimuli. Importantly, slow presentation of auditory tone bursts produced response amplitude changes approximating those observed following tetanisation in younger adults. Meta-analyses of visual and auditory tetanisation studies found that the overall effect of sensory tetanisation was not significant across studies or study sites. Androgen Receptor Antagonist library The results suggest that sensory tetanisation may not produce reliable changes in cortical responses and more work is needed to determine the validity of sensory tetanisation as a method for inducing human cortical plasticity in vivo.
Patients with cervical spondylotic myelopathy (CSM) can be treated with posterior approaches for spinal canal decompression.

We compared the patients' outcome after 2 different unilateral and a bilateral posterior approach for decompression to elucidate feasibility and potential procedure-related differences.

Medical records of 98 patients with CSM undergoing posterior decompression between 2012 and 2018 were assessed. Patients were divided into 3 groups (1) unilateral interlaminar fenestration with over-the-top "undercutting" (laminotomy) for compression limited to a ligamentum flavum hypertrophy, (2) unilateral hemilaminectomy for lateralized compression with a combination of ligamentous hypertrophy and osseus stenosis, and (3) laminectomy/laminoplasty for circular osseous-ligamentous spinal canal narrowing.

The mean age was 73 years (mf = 1.41), and most frequent symptoms (mean duration 15 months) were ataxia (69%) and sensory changes (57%). Main location of stenoses (median Naganawa Score = 3; meacompression and comparable long-term results.
To minimize patients' periprocedural burden in CSM with dorsal compression, individual tailoring of the posterior approach according to the underlying compressive pathology achieves sufficient decompression and comparable long-term results.
Intraparenchymal hemorrhage (IPH) is a debilitating and highly morbid type of stroke with limited effective treatment modalities. Minimally invasive evacuation with tissue plasminogen activator (rt-PA) has demonstrated promise for mortality/functional improvements with adequate clot volume reduction. In this study, we report 2 cases of continuous rt-PA infusion using a closed circuit, dual lumen catheter, and irrigation system (IRRAflow) for IPH treatment.

A 55-year-old man was admitted for acute onset left hemiparesis; he was found to have right basal ganglia IPH. He was treated with continuous rt-PA irrigation using the IRRAflow device, at a rate of 30 mL/h for 119 hours, with a total volume reduction of 87.8 mL and post-treatment volume of 1.2 mL. At 3-month follow-up, he exhibited a modified Rankin score of 4 and improved hemiparesis. A 39-year-old woman was admitted for acute onset left facial droop, left hemianopsia, and left hemiparesis; she was diagnosed with a right basal ganglia IPH. She was trecerebral Hemorrhage Evacuation (MISTIE) approach but offers the potential advantages of less breaks in the sterile circuit, continuous intracranial pressure monitoring, and may provide more efficient clot lysis compared with intermittent bolusing.
Lumbar drain placement is a common neurosurgical procedure, with several surgical and medical indications extending even beyond the specialty. One complication of placement is a fractured catheter fragment. In some circumstances, catheter retrieval is necessary which is classically performed through an open approach. Here, we present the only reported case of a retained lumbar drain catheter which was retrieved using a transforaminal endoscopic approach to the lumbar spine.

This is a 39 year-old woman who underwent an elective craniotomy with planned perioperative lumbar drain placement for cerebrospinal fluid diversion using a 14-gauge Tuohy needle. Placement was noted to be technically challenging, and during the final attempt on removal of the system, it was noted that the distal end of the catheter had been sheared and retained in the thecal sac. Postoperatively a computed tomography scan of the lumbar spine was obtained showing the catheter fragment which entered the thecal sac dorsally at the L3-4 level but penetrated the ventral dura traveling in the epidural space caudally and terminating in the left lateral recess of L4-5. Given its presumed epidural location near the left L4-5 lateral recess and foramen, the decision was made to attempt a left transforaminal endoscopic approach for catheter retrieval before resorting to a standard open surgery.

As minimally invasive spine techniques for spine surgery continue to evolve, we have highlighted the versatility of the endoscope in spine surgery as it was implemented in our case, allowing for reduced perioperative morbidity associated with retained spinal catheter retrieval.

Detailed anatomic visualization of the root entry zone of the trigeminal nerve is crucial to successfully perform microvascular decompression surgery (MVD) in patients with trigeminal neuralgia.

To determine advantages and disadvantages using a 3-dimensional (3D) exoscope for MVD surgery.

A 4K 3D exoscope (ORBEYE) was used by a single surgical team for MVD in a retrospective case series of 8 patients with trigeminal neuralgia in a tertiary center. Clinical and surgical data were collected, and advantages/disadvantages of using the exoscope for MVD were recorded after each surgery. Descriptive statistics were used to summarize the data.

Adequate MVD of the trigeminal nerve root was possible in all patients by exclusively using the exoscope. It offered bright visualization of the cerebellopontine angle and the root entry zone of the trigeminal nerve that was comparable with a binocular operating microscope. The greatest advantages of the exoscope included good optical quality, the pronounced depth of field of the image for all observers, and its superior surgeon ergonomics. Disadvantages were revealed with overexposure at deep surgical sites and the lack of endoscope integration. In 6 patients, facial pain improved significantly after surgery (Barrow Neurological Institute pain intensity score I in 5 and III in 1 patient), whereas it did not in 2 patients (Barrow Neurological Institute score IV and V). No complications occurred.

Utilization of a 3D exoscope for MVD is a safe and feasible procedure. Surgeons benefit from better ergonomics, excellent image quality, and an improved experience for observers.
