To use computed tomography angiography to evaluate the regional anatomy of the lumbar segmental arteries (LAs) associated with the surgical field in oblique lateral interbody fusion (OLIF). ⋯ The risk of LA injury during OLIF is the least when the cage is placed in zones II and III. Care is required during OLIF in zone IV of L3-L5. The fixation pin should be fixed on the upper edge of the lower vertebral body at L1-L2 and L2-L3, and on the lower edge of the upper vertebral body at L3-L4 and L4-L5.

Increasing evidence points monocytes' role to be larger than thought in developing cerebral infarction (CI) after subarachnoid hemorrhage (SAH). However, there is no clinical evidence of the relationship between peripheral monocytes and CI and clinical outcomes. Therefore we determine whether an increase in monocytes in the acute phase is useful to predict CI and functional outcomes in SAH patients. ⋯ Increased peripheral monocytes at admission is a risk factor for developing CI after SAH. Moreover, short- and long-term poor clinical outcomes were associated with higher monocyte count. Therefore monocytes could be a convenient biomarker for prognosis unfavorable outcomes and a possible target for new therapeutic strategies.

Comparison of Minimally Invasive and Pterional Craniotomies for Ruptured Anterior Circulation Aneurysms: A Propensity Score-Matched Analysis.
Minimally invasive craniotomy (MIC) for ruptured aneurysm remains a debatable issue because of unclear information regarding its safety and efficacy compared with standard approaches. Here, we compared the outcomes between MIC and pterional craniotomy (PTC) for the treatment of ruptured anterior circulation aneurysms. ⋯ For the treatment of ruptured anterior circulation aneurysms, MIC was comparable with PTC and presented additional advantage in terms of earlier recovery. Therefore, MIC can be considered an alternative surgical treatment in this setting.

Since their advent in the 1920s, tear gas canisters (TGCs) have been frequently used in crowd control. Few reports have documented nonpenetrating injuries attributed directly to TGCs. In this study, we report a case series of fatal penetrating head injuries caused by TGCs. ⋯ TGCs have the potential to cause lethal penetrating head injuries, calling for a reevaluation of their safety and methods of use in terms of human health.
