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.

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.

Minimal access posterior approach for extrapleural thoracic sympathectomy: a cadaveric study and cases.
Operatively, video-assisted thoracoscopic sympathectomy (VATS) involves pleural entry and poses risk in small children and patients with pulmonary disease. A conventional posterior sympathectomy is more invasive than VATS. We investigated a cadaveric feasibility study of a minimal access posterior approach for endoscopic extrapleural sympathectomy and discuss this minimal approach in children with cardiac sympathectomy. ⋯ Minimal access posterior extrapleural sympathectomy is feasible to expose the sympathetic chain in the thoracic region with good visualization using either endoscopic or microscopic magnification. Single-position bilateral thoracic sympathectomy can be performed in pediatric patients with life-threatening ventricular arrhythmias. Based on the cadaveric study and the 2 preliminary cases, we believe that a posterior minimal access approach allows safe and effective access to the thoracic sympathetic chain for causes requiring sympathectomy using single positioning, with minimal risk of pneumothorax or Horner syndrome.

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.

In sacropelvic fixation, the iliac screw technique offers biomechanically strong constructs, but its disadvantages include screw prominence, wound dehiscence, and postoperative pain secondary to the high profile nature. To overcome this drawback, S2-alar-iliac (S2AI) screws were developed as an alternative technique for sacropelvic fixation. This study aimed to compare the S2AI screw technique with the iliac screw technique in terms of postoperative symptomatic screw prominence. ⋯ The use of the S2AI screw technique resulted in a reduced rate of symptomatic screw prominence. MDSS ≤23 mm was the strongest predictor of symptomatic screw prominence.
