Mild traumatic brain injury (mTBI), defined as blunt trauma to the head resulting in witnessed loss of consciousness, definite amnesia, or witnessed disorientation with a Glasgow Coma Scale (GCS) score of 14 or 15 is a common occurrence in the emergency department. In mTBI, oral anticoagulation is known to be an important risk factor for hemorrhage. Clinical guidelines recommend baseline computed tomographic (CT) scan and observation for 24 hours plus a CT scan before discharge. ⋯ Patients with a GCS score of 15 who are taking long-term anticoagulation therapy and who present with mTBI have a risk of cranial hemorrhage that is likely to be similar to that of non-anticoagulated patients. It may be reasonable to envision a protocol including only one CT scan and an appropriate observation period.

Cerebrospinal fluid (CSF) culture is the gold standard for diagnosing postoperative central nervous system infection. The time to positivity (TTP) of an automated continuous blood culture system may indicate the original concentration of the organism. Coagulase-negative Staphylococcus (CoNS), the common organism recovered in CSF, poses difficulty in differentiating infection from contamination. This study investigated the TTP of CSF culture with CoNS and its relationship to clinical parameters and prognosis. ⋯ Targeted antibiotic therapy was more likely to be beneficial to patients with a rapid TTP within 7 days, which suggested that CoNS with a rapid TTP represents the pathogen of central nervous system infection rather than contamination in neurosurgical patients.

Subgaleal masses are relatively common in the clinical praxis, and after a trauma to the head, a subgaleal hematoma is usually suspected. However, other differential diagnoses, such as malignant tumors, should be kept in mind despite a history of a previous trauma. ⋯ We report a case of a subgaleal mass that was clinically and radiologically diagnosed as a subgaleal hematoma in a patient on antiplatelet therapy. The patient had a history of trauma to her head, but pathologic examination after surgery unexpectedly showed a malignant B-cell lymphoma. A review of the literature is also presented.

Meningiomas account for approximately one third of all brain tumors in the United States. In high-volume medical centers, the average length of stay (LOS) for a patient is 6.8 days compared with 8.8 days in low-volume centers with median total admission charges equaling approximately $55,000. To our knowledge, few studies have evaluated day of surgery and its effect on hospital LOS. Our primary goal was to analyze patient outcome as a direct result of surgical date, as well as to characterize the individual variables that may impact their hospital course, early access to rehabilitation, and long-term functional status. ⋯ Day of surgery may play a significant role in LOS for meningioma patients. Clinicians should remain aware of those factors that may delay optimal patient discharge and early access to rehabilitation facilities. Further studies will need to be performed to assess the social variables that may affect LOS, as well as the financial implications for such extended hospital courses.
