Monitoring optic nerve sheath by ultrasound can be considered a reliable method for identifying severe intracranial hypertension in patients with large vessel occlusion, as well as for monitoring patients undergoing craniectomy. Additional studies will be necessary to include this parameter in craniectomy indication algorithms in the future.

Cancer can present as stroke. Several cancer types have established screening guidelines. We investigated adherence to guideline-recommended cancer screening in stroke survivors versus the general population.

We performed a cross-sectional analysis using 2012-2018 data from the CDC's Behavioral Risk Factor Surveillance System (BRFSS) survey. BRFSS is a nationally-representative telephone survey of non-institutionalized Americans that collects data about health conditions and behaviors, including cancer screening. We defined guideline-recommended colorectal, lung, and breast cancer screening based on the U.S. Preventive Services Task Force recommendations. We used survey-specific methods to estimate up-to-date screening rates for those with and without prior stroke. We used logistic regression to estimate the odds of up-to-date screening in stroke survivors compared to those without history of stroke after adjustment for potential confounders.

Among 1,018,440 respondents eligible for colorectal cancer screening, 66% were up-to-date. Among 6,880 respondents eligible for lung cancer screening, 16% were up-to-date. Among 548,434 women eligible for breast cancer screening, 78% were up-to-date. After adjustment for demographics and confounders, stroke survivors were more likely to have up-to-date colorectal cancer screening (OR, 1.10; 95% CI, 1.05-1.16), equally likely to undergo lung cancer screening (OR, 0.99; 95% CI, 0.62-1.59), and less likely to undergo breast cancer screening (OR, 0.87; 95% CI, 0.80-0.94).

In a nationwide analysis, stroke survivors had similar suboptimal adherence to guideline-recommended cancer screening as the general population.

This is the first case of delayed tracheal perforation post total thyroidectomy in the context of previous radiotherapy to the neck. Such a presentation can be easily misdiagnosed and managed as a seroma at significant risk to the patient, as the latter had no precipitating factors and cardiorespiratory compromise. There are nineteen previously described cases of delayed tracheal injury post thyroidectomy of variable severity and variable intervention.

A 51-year-old man presented with non-tender anterior neck surgical emphysema initially diagnosed on bedside ultrasound and plain X-ray, 22days following total thyroidectomy and central neck dissection. His background was significant for childhood acute lymphoblastic leukaemia requiring chemotherapy and cranio-spinal radiotherapy. He underwent total thyroidectomy, for multiple bilateral thyroid nodules found on cranio-spinal MRI surveillance concerning for follicular neoplasm. There were significant amount of adhesions tethering the thyroid secondary to prior radiotherapy but no tracheal injury intra-operatively.

At presentation, no source of air leak was identified on Computer Tomography. He failed conservative management. During surgical exploration, a 2mm tracheal perforation at the right cricothyroid joint was closed with the right sternothyroid muscle due to the proximity of the perforation with the recurrent right laryngeal nerve. Tisseel was applied over the repair. He recovered without further complications.

Sudden onset neck swelling post thyroidectomy in the context of significant scaring from radiotherapy, should raise the suspicion of surgical emphysema in the neck patients and confirmed with plain x-ray. Such patients should have multidisciplinary tertiary care.

In the past, mucinous appendiceal neoplasms (MAN) greater than 2cm in diameter were treated by a right colon resection. New data shows that treatment options are to be determined by the histopathologic grade of the appendiceal tumor and the condition of the wall of the appendix (intact vs. breached).

A 39-year-old woman had an incidental diagnosis of a low-grade appendiceal mucinous neoplasm (LAMN) at the time of a hysterectomy. The appendiceal tumor had small quantities of mucus surrounding an enlarged appendix. No tumor cells were seen in the mucus by histologic study. The patient was placed in follow-up. Eighteen years later she required treatment for advanced pseudomyxoma peritonei.

When 5 different histopathologic types of MAN are considered with an intact vs. perforated wall of the appendix, four different treatment options develop. With LAMN and well or moderately differentiated mucinous appendiceal adenocarcinoma (MACA), the patient does not require operative intervention if the wall of the appendix is intact. If mucus or mucus plus tumor cells are identified outside the appendix an intervention is indicated. In patients, as the one presented, in whom only small amounts of mucus are outside the appendix, surveillance may be recommended.

In patients with a diagnosed low-grade MAN, dissemination to regional lymph nodes is rare. Dissemination to the peritoneal space places the patient at risk to develop pseudomyxoma peritonei. As this case report illustrates, if surveillance is recommended, long-term follow-up is required.

A broadly used mite control regimen is based on two organic molecules formic and oxalic acids. To ensure optimal efficiency, several applications of these acids at pre-defined time points are recommended. These recommendations are mainly based on experiments conducted under controlled conditions. Studies evaluating the effectiveness under natural field conditions are lacking. We enrolled 30 beekeepers in a longitudinal study in three cantons in Switzerland and monitored the management and health of their colonies for two years. We assessed compliance with mite control recommendations and measured V. destructor infestation rates, indexes of colony productivity (brood size and honey harvest), and colony mortality in 300 colonies. We observed a 10-fold increased risk of colony death when beekeepers deviated slightly from the recommended treatment regimennces to further promote honey bee health.The recent introduction of Transcranial Alternating Current stimulation (tACS) in research on memory modulation has yielded some exciting findings. Whilst evidence suggests small but significant modulatory effects of tACS on perception and cognition, it is unclear how effective tACS is at modulating memory, and the neural oscillations underlying memory. The aim of this systematic review was to determine the efficacy with which tACS, compared to sham stimulation, can modify working memory (WM) and long-term memory (LTM) performance in healthy adults. We examined how these effects may be moderated by specific tACS parameters and study/participant characteristics. Our secondary goal was to investigate the neural correlates of tACS' effects on memory performance in healthy adults. A systematic search of eight databases yielded 11,413 records, resulting in 34 papers that included 104 eligible studies. The results were synthesised by memory type (WM/LTM) and according to the specific parameters of frequency band, stimulation montage, individual variability, cognitive demand, and phase. A second synthesis examined the correspondence between tACS' effects on memory performance and the oscillatory features of electroencephalography (EEG) and magnetencephalography (MEG) recordings in a subset of 26 studies. The results showed a small-to-medium effect of tACS on WM and LTM performance overall. There was strong evidence to suggest that posterior theta-tACS modulates WM performance, whilst the modulation of LTM is achieved by anterior gamma-tACS. Moreover, there was a correspondence between tACS effects on memory performance and oscillatory outcomes at the stimulation frequency. We discuss limitations in the field and suggest ways to improve our understanding of tACS efficacy to ensure a transition of tACS from an investigative method to a therapeutic tool.When a visual event is unexpected, because it violates a train of repeated events, it excites a greater positive electrical potential at sensors positioned above occipital-parietal human brain regions (the P300). Such events can also seem to have an increased duration relative to repeated (implicitly expected) events. However, recent behavioural evidence suggests that when events are unexpected because they violate a declared prediction-a guess-there is an opposite impact on duration perception. The neural consequences of incorrect declared predictions have not been examined. We replicated the finding whereby repetition violating events elicit a larger P300 response. However, we found that events that violated a declared prediction entrained an opposite pattern of response-a smaller P300. These data suggest that the neural consequences of a violated prediction are not uniform but depend on how the prediction was formed.Reflecting a 'participatory turn' in healthcare, a variety of activities have been adopted in many countries to harness the views of patients, relatives and service users. While celebrated as a way of empowering patients and increasing the legitimacy of decisions that impact on patient care, critics contend that practices of patient participation often fall short of the ideals they purport to implement. In this article, we investigate how patients' participation in medical priority setting corresponds with the regulative ideals of deliberation and how the practices of participation influence the ability of patients to make their voices heard. Building on document analysis and semi-structured interviews with 12 patient representatives and four scientific officers in the Danish Medicines Council, the analysis demonstrates that conflicting notions of valid knowledge constituted a main challenge for patient participation. The study contributes to the literature on patient participation through a conceptualization of four co-existing participant roles 1) compliant keepers of experiential knowledge, 2) lay experts investing in evidence production, 3) knowledge translators engaged in alliance building, and 4) demonstrators promoting public contestation.
