These results could deepen the understanding of the antiradical activity and mechanism of DHCs, which will facilitate the design of novel efficient antioxidants.

Satellite sign is a novel neuroimaging marker for predicting hematoma expansion (HE), which is closely related to unfavorable prognosis in patients with spontaneous intracerebral hemorrhage (ICH). However, the predictive value of satellite sign varied according to previous studies. Thus, we conduct this meta-analysis to systematically review the application value of satellite sign in related studies.

We searched the literature in PubMed, Embase, and Web of Science from inception to April 10, 2020. Effect values, including sensitivity, specificity, and positive and negative likelihood ratio were pooled to assess the diagnostic value of satellite sign for HE in patients with ICH.

The meta-analysis included five studies with a total of 1493 patients. Results showed that the pooled diagnostic sensitivity and specificity were 0.50 (95 % CI, 0.31-0.70) and 0.71 (95 % CI, 0.56-0.83), respectively. In addition, the pooled positive and negative likelihood ratios were 1.7 (95 % CI, 1.5-2.1) and 0.70 (95 % CI, 0.54-0.89), respectively. VX-11e No significant publication bias was found.

Satellite sign exhibited moderate sensitivity and specificity for predicting HE in patients with ICH. Further studies are needed to explore its value in clinical application.

Cavernous Sinus Thrombosis is a rare but serious condition. Despite increasingly effective treatment, the mortality and risk of long-term sequelae remains significant. The objective of this study is to describe the case of a 62 year old female presenting to a cardiovascular clinic with symptoms indicating an atypical subacute cavernous sinus thrombosis secondary to a dental procedure, and review the literature regarding cavernous sinus thrombosis following dental procedures and dental infections.

The study design is a Case Report and Systematic Review. A PubMed literature search was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines, and limited to studies published between 2015 and 2020 (April).

The case describes a 62 year old female with a 5 month history of left upper eyelid swelling, diplopia, chemosis, ptosis, and left sided cluster headache who was diagnosed with subacute cavernous sinus thrombosis treated with oral anticoagulation. Tain an MRV to rule out CST when stumbling upon ocular symptoms or infections in the danger triangle of the face following a dental procedure or infection. Despite the conflicting views on the benefits of anticoagulation in the setting of CST, the addition of oral anticoagulation yielded a positive outcome in our patient.Pain after supratentorial craniotomy is common, 55 % to 80 % of patients experience moderate to severe pain in the first 48 h(1-7). The importance of intravenous dexamethasone as an adjuvant to local anaesthetics is increasingly applied(1-7), however its role in scalp nerve blocks with ropivacaine 0.75 % remains unexplored in post-operative analgesia. We analyzed 134 supratentorial craniotomies under general anaesthesia, 46 of which had preoperatively bilateral scalp nerve blocks with ropivacaine 0.75 %. The general anaesthesia was standardized and included 8 mg of intravenous dexamethasone at the induction. The postoperative pain was assessed using the numerical rating scale with patients in the post anaesthesia care unit and subsequently every 8 h in the neurosurgery unit until the 48th hour. A NRS value above 3 led to the administration of a rescue analgesic according to the defined protocol until an efficient analgesia was obtained. Postoperative pain was controlled in both groups, however the need for rescue analgesics in the scalp nerve blocks group was reduced by 40 % (39 % vs. 65 %; p = 0.006) compared to the control group. More than 60 % of the patients from the scalp nerve blocks group had an efficient analgesia without any rescue analgesic. Peroperatively the scalp nerve blocks group showed a decrease in opioid consumption and a better hemodynamic stability. No anesthetic or chirurgical complications related to the use of scalp blocks were observed. Scalp nerve blocks associated with intravenous dexamethasone are found to be a straightforward and efficient analgesic approach during supratentorial craniotomies.

Prediction of the rupture risk in anterior communicating artery (ACoA) aneurysms remains challenging. We aimed to investigate the association of detailed morphologies with ACoA aneurysm rupture.

759 consecutive patients with ACoA aneurysms were identified from December 2007 to January 2016. An independent cohort was collected for validation from March 2017 to October 2019. Morphological parameters of the aneurysms were measured using CT angiography. Univariable and multivariable analyses were used to investigate the association of morphological characteristics with aneurysm rupture. Area under receiver operating characteristic curves (AUC) were used to assess the performance of the model.

A total of 650 patients with 650 ACoA aneurysms were included for the derivation, and 41 patients with 41 ACoA aneurysms were included for the validation. Aneurysm size, neck size, aspect ratio, size ratio, vessel angle, anterior projection, dominant A1 segment, irregular shape, the presence of a daughter dome, vessel size, and aneurysm angle were risk factors for rupture. The multivariable analysis showed that a larger aneurysm, anterior projection of aneurysms, dominant A1 segment, and irregular aneurysms were associated with aneurysm rupture, whereas larger vessel size was inversely associated with rupture. The morphological risk score showed good discrimination of ruptured and unruptured aneurysms with an AUC of 0.73 in the derivation and an AUC of 0.80 in the validation, and good calibration in both cohorts, signifying a good fit.

The morphological risk model may contribute to evaluating the risk of rupture of ACoA aneurysms.
