studies, involving ECoG and EEG could help determine their association with epileptogenesis.
SDs are common in the cortex of ischemic or traumatic penumbra. Our study suggests an association between the presence of SDs in the acute phase and worse long-term outcome, although no association with subsequent epilepsy was found. More comprehensive studies, involving ECoG and EEG could help determine their association with epileptogenesis.The aim of this narrative review is to describe the toxicologic confounders of brain death currently reported in the literature to offer guidance for physicians assessing brain death after a toxic exposure. We established an a priori definition of a "brain death mimic" as an unresponsive, intubated patient missing some, but not all brainstem reflexes. We completed a review of the literature utilizing MEDLINE and EMBASE to find case reports of patients of all ages in English, French, and Spanish meeting the criteria and hand searched the references of the results. We recorded xenobiotic dose, duration of physical exam suggesting brain death, and how the cases failed to meet full brain death criteria, when available. Fifty-six cases representing 19 different substances met the a priori definition of brain death mimic. Xenobiotic toxicities included snake envenomation (13), baclofen (11), tricyclic antidepressants (8), bupropion (7), alcohols (4), antiepileptic agents (3), barbiturates (2), antidysrhythmics (2), organophosphates (2), and one case each of magnesium, succinylcholine, tetrodotoxin, and zolpidem. All patients except one survived to discharge and the majority at their baseline physical health. The most common means by which the cases failed brain death examination prerequisites was via normal neuroimaging. The xenobiotics in this review should be considered in cases of poisoning resulting in loss of brainstem reflexes and addressed before brain death determination. Brain death diagnosis should not be pursued in the setting of normal cerebral imaging or incomplete evaluation of brain death prerequisites.
To determine the added value of mammography in women with focal breast complaints and the utility of initial targeted ultrasound in this setting.

Women with symptomatic breast disease who were evaluated by breast imaging (mammography/digital breast tomosynthesis and ultrasound) between January 2016 and December 2016 in the Radboud University Medical Centre were included. We retrospectively collected the following data date of birth, indication of imaging, visibility on mammography/ultrasound, whether biopsy was taken, additional findings, BI-RADS-classification, pathology and follow-up results.

A total of 494 women were included (mean age 46.5, range 30 to 93). In 49 women (9.9%), symptomatic breast cancer was diagnosed, all visible during targeted ultrasound. The negative predictive value of targeted ultrasound was very high (99.8%). Additional findings on mammography were significantly more often malignant when the symptomatic lesion was also malignant (3.8% vs 70%, P < 0.05). In only one patient with symptoms caused by a benign finding, an incidental malignancy was detected on mammography outside the area of complaint (detection rate 2.2/1000 examinations).

The contribution of mammography for cancer detection in women with focal breast complaints is very low when targeted ultrasound is performed. Additional findings are most common in patients with symptomatic breast cancer. Our results suggest that initial targeted ultrasound is a more appropriate initial tool for the evaluation of focal breast complaints. Mammography could be performed on indication only.

The rate of risk-reducing bilateral mastectomy (RRBM) among cancer-free Israeli female BRCA1/BRCA2 mutation carriers was reportedly 13% in 2010. Current RRBM rates in Israel and factors seemingly associated with opting for RRBM were reevaluated.

Israeli female cancer-free BRCA1/BRCA2 mutation carriers, who were followed at the high-risk clinic at Sheba Medical Center between January 2011 and April 2020 were eligible. Univariate Cox regression and log-rank test were used to study the crude association between potential predictors and performance of RRBM.

Overall, 427 cancer-free BRCA1 (n = 218) or BRCA2 (n = 209) mutation carriers were included. Median age at genotyping was 33.6years (interquartile range 26.8-41.8years), median follow-up 4.4years (range 0.1-7.6years). Overall, 41/427 (9.6%) participants underwent RRBM, all of them within 5years of genotyping. Being married (HR-2.57, p = 0.017) and having a first degree relative with breast cancer (BC) (HR-2.19, p = 0.017) were positively associated with RRBM, whereas any previous benign breast biopsy was negatively associated (HR-0.48, p = 0.029) with performing RRBM.

RRBM is still infrequently elected by Israeli BRCA1/BRCA2 mutation carriers, with married women with one relative with BC who have not undergone previous breast biopsy more likely to opt for RRBM.

The prevalence of trypanosome and piroplasm infections in horses and resistance profile of isolated trypanosomes to diminazene and isometamidium salts were investigated. For the cross-sectional study of horses billed for slaughter, 304 horses were randomly sampled. Approximately 2 ml of blood was collected into anticoagulant-treated bottles for haematocrit (HCT) determination, direct microscopic examinations, and rat inoculation. Gender, body condition scores (BCS), age groups, and body weights of sampled horses were noted. Two isolates of Trypanosoma brucei recovered from the cross-sectional study were profiled for resistance to isometamidium hydrochloride and diminazene diaceturate in 36 BALB/c mice. GSK621 Standardized protocols were used (Eisler et al., Veterinary Parasitology 97171-182, 2001). 19.1% of horses (95% confidence interval 14.7-23.5%) were positive for haemoparasite infections including Theileria equi (16.
