This study sought to 1) describe the use K-wireless pedicle screw insertion among adults (age ≥18 years) undergoing a minimally invasive fusion and 2) perform a systematic review (SR) of all studies that describe a navigated, K-wireless technique with 3-dimensional fluoroscopy. ⋯ Percutaneous pedicle screws can be placed accurately and safely using 3-dimensional navigation without the use of K-wires and may confer benefits to patients and clinicians by reducing K-wire-associated complications and radiation exposure.

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.

The aim to evaluate central sarcopenia, as measured by psoas cross-sectional area on admission imaging, is associated with outcomes in patients with vertebral compression fractures (VCFs) treated with percutaneous vertebral augmentation treatment. ⋯ There is a significant correlation between sarcopenia and postoperative mortality after vertebral augmentation procedure in patients with VCFs.

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.

Germinomas are rare intracranial lesions, with medulla germinomas being reported in only approximately 20 cases to date. These tumors are extremely sensitive to radiotherapy, and knowledge of them can allow for accurate diagnosis as well as significantly impact treatment and prognosis. ⋯ A few imaging characteristics are noted in multiple cases, such as cystic components, enhancement, and absence of hydrocephalus. These features can provide clues to diagnosis of this rare entity.
