Study Design. A retrospective study was conducted. Objective. This study aims to analyze the feasibility and efficacy of using minimal access spinal surgery (MASS) for managing thoracic spine metastasis. Summary of Background Data. Literature regarding minimally invasive surgical treatment for thoracic spine metastasis is sparse. In the past decade, the role of minimally invasive or endoscopic technique in managing metastatic thoracic disease has evolved. Methods. From February 1997 to March 2003, 46 patients with spine metastases, from T3–T12, were enrolled in this study. There were 29 patients undergoing MASS. Seventeen patients received standard thoracotomy (ST) in the early study period served as the control group. The indications for MASS include intractable back pain and/or neurologic deficits or neurologic deterioration during or after radiotherapy. Inclusion criteria for this study included tumor limited to one or two vertebral segments. Results. In the MASS and ST groups, no patient died as a result of an immediate intraoperative event. The mean operative blood loss was 1,110 versus 1,162 mL (P = 0.63), and the mean operative length was 179 versus 180 minutes (P = 0.54). Complication rates and 1-year, 2-year, and overall survival rates were comparable and the mean grade of neurologic recovery was 1.2 on the Frankel scale in both groups. Only 6.9% of MASS patients required a 2-day postoperative ICU stay compared with 88% of ST patients (P < 0.0001). Conclusions. The MASS technique is safe and effective and has proved to be an excellent alternative in managing thoracic spine metastasis. Surgeons may use progressively smaller incisions (5–6 cm in length) for the procedure. The learning curve for performing MASS procedures was not steep.
Background: Vibrio and Aeromonas species, which can cause necrotizing fasciitis and primary septicemia, are members of the Vibrionaceae family and thrive in aquatic environments. Because the clinical symptoms and signs of necrotizing fasciitis and sepsis caused by these two bacteria are similar, the purposes of this study were to describe the clinical characteristics of Vibrio vulnificus and Aeromonas infections, to analyze the risk factors for death, and to compare the effects of surgical treatment on the outcome. Methods: The cases of thirty-two patients with necrotizing soft-tissue infections and sepsis caused by Vibrio vulnificus (seventeen patients) and Aeromonas species (fifteen patients) were retrospectively reviewed over a four-year period. Surgical débridement or immediate limb amputation was initially performed in all patients. Demographic data, underlying diseases, laboratory results, and clinical outcome were analyzed for each patient in both groups. Results: Six patients in the Vibrio vulnificus group and four patients in the Aeromonas group died. The patients who died had significantly lower serum albumin levels than did the patients who survived (p < 0.05). The patients with a combination of hepatic dysfunction and diabetes mellitus had a higher mortality rate than those with either hepatic disease or diabetes mellitus alone (p < 0.05). The patients with Vibrio vulnificus infections had a significantly lower systolic blood pressure at presentation (p = 0.006). The patients with Aeromonas infections who died had significantly lower white blood-cell counts (p = 0.03) with significantly fewer numbers of segmented white blood cells than those who died in the Vibrio vulnificus group (p = 0.01). Conclusions: The contact history of patients with a rapid onset of cellulitis can alert clinicians to a differential diagnosis of soft-tissue infection with Vibrio vulnificus (contact with seawater or raw seafood) or Aeromonas species (contact with fresh or brackish water, soil, or wood). Early fasciotomy and culture-directed antimicrobial therapy should be aggressively performed in those patients with hypotensive shock, leukopenia, severe hypoalbuminemia, and underlying chronic illness, especially a combination of hepatic dysfunction and diabetes mellitus.

Background: Pseudomeningoceles are a rare complication after spinal surgery, and studies on these complex formations are few. Methods: Between October 2000 and March 2008, 11 patients who developed symptomatic pseudomeningoceles after spinal surgery were recruited. In this retrospective study, we reported our experiences in the management of these complex, symptomatic pseudomeningoceles after spinal surgery. A giant pseudomeningocele was defined as a pseudomeningocele >8 cm in length. We also evaluated the risk factors for the formation of giant pseudomeningoceles. Results: All patients were treated successfully with a combined treatment protocol of open revision surgery for extirpation of the pseudomeningoceles, repair of dural tears, and implantation of a subarachnoid catheter for drainage. Surgery-related complications were not observed. Recurrence of pseudomeningocele was not observed for any patient at a mean follow-up of 16.5 months. This result was confirmed by magnetic resonance imaging. Conclusions: We conclude that a combined treatment protocol involving open revision surgery for extirpation of pseudomeningoceles, repair of dural tears, and implantation of a subarachnoid catheter for drainage is safe and effective to treat giant pseudomeningoceles.

Poses We (1) asked whether the clinical indicators could predict laboratory findings during the initial stage of Vibrio necrotizing fasciitis and (2) determined the relationships between the laboratory risk indicator for necrotizing fasciitis (LRINEC) score and the diagnosis of Vibrio infection. Methods We retrospectively reviewed 70 patients with 71 episodes of Vibrio necrotizing fasciitis and sepsis. Of the 70 patients, 68 had a history of contact with seawater or raw seafood; 66 had underlying chronic diseases. Results Eighteen patients (25.7%) died a mean 18.7 days after admission, and 52 patients survived. A systolic blood pressure of 90 mm Hg or less at the time of admission to the emergency room was associated with mortality. Patients who died had lower leukocyte counts, segmented leukocyte counts, platelet counts, and serum albumin levels compared with the patients who survived and higher counts of band forms of leukocytes. Only eight patients (11%) who survived had a LRINEC score of 6 or greater. Conclusions The LRINEC scoring system is not applicable when treating such a highly lethal disease. We propose that severe hypoalbuminemia, severe thrombocytopenia, and increased banded forms of leukocytes are laboratory risk indicators of necrotizing fasciitis that aid in pointing toward initiation of early surgery and predict a higher risk of death.
