Postoperative Cerebral Venous Sinus Thrombosis Following a Retrosigmoid Craniotomy-A Clinical and Radiological Analysis.

Postoperative cerebral venous sinus thrombosis (CVST) is a rare complication of the retrosigmoid approach. To address the lack of literature, we performed a retrospective analysis. The thromboses were divided into those demonstrating radiological (rCVST) and clinical (cCVST) features, the latter diagnosed during hospitalization. We identified the former by a lack of contrast in the sigmoid (SS) or transverse sinuses (TS), and evaluated the closest distance from the craniotomy to quantify sinus exposure. We included 130 patients (males: 52, females: 78) with a median age of 46.0. They had rCVST in 46.9% of cases, most often in the TS (65.6%), and cCVST in 3.1% of cases. Distances to the sinuses were not different regarding the presence of cCVST (p = 0.32 and p = 0.72). The distance to the SS was not different regarding rCVST (p = 0.13). However, lower exposure of the TS correlated with a lower incidence of rCVST (p = 0.009). When surgery was performed on the side of the dominant sinuses, rCVSTs were more frequent (p = 0.042). None of the other examined factors were related to rCVST or cCVST. Surgery on the side of the dominant sinus, and the exposing of them, seems to be related with rCVST. Further prospective studies are needed to identify the risk factors and determine the best management.

The COVID-19 Crisis and the Incidence of Alcohol-Related Deaths in Poland.

BACKGROUND Identifying risk and protective factors for excessive alcohol consumption can inform targeted health policies, reducing the impact of potential mental health crises. This study examined the validity and reliability of COVID-19-related death data and explored the correlations among age, sex, residential status, alcohol abuse, and healthcare access. MATERIAL AND METHODS This analysis of Polish residents' mortality relies on individual data from the register of deaths maintained by Statistics Poland. This study examined deviations in the number of deaths between 2020 and 2021 by analyzing specific causes of death. RESULTS Alcohol abusers had increased COVID-19 risk factors compared to the general population. F10 values were 22% higher than expected in 2020, aligning with predictions for 2021. Higher mortality rates were observed in the first year of the pandemic. In 2020, women and rural residents were more affected (31% and 25% higher than expected, respectively), while men and urban residents were less affected (21% and 20% higher than expected, respectively). In 2021, the trend reversed, with men 2% higher than predicted and women 4% lower. Urban area residents had a 77% lower than expected value, while rural area residents were similar (8% higher). Overall mortality exceeded expectations in both 2020 (13% higher) and 2021 (23% higher). In 2021, alcohol-related non-mental health problems increased by more than 40% in standardized death rates (SDRs). CONCLUSIONS Alcohol-related deaths reflect the hidden effects of the pandemic. Measuring the pandemic's impact on global excess mortality is hindered by inconsistencies in COVID-19 death reporting.
