BACKGROUND: Transforaminal epidural injection (TEI) is commonly used in the treatment of radicular pain. However, there have been many published cases of serious complications after a TEI, occurring most often in cervical levels. One of the presumptive reasons for this complication is inadvertent intravascular injection. We sought to identify the incidence of intravascular injections in cervical and lumbar spinal segments during TEI.

METHODS: All patients with radicular symptoms or herpes zoster-associated pain underwent cervical and lumbar TEIs (LTEIs) prospectively by one of the authors. After an ideal needle position was confirmed by biplanar fluoroscopy, 3 mL of a mixture containing nonionic contrast and normal saline was continuously injected at the rate of 0.3–0.5 mL/s with real-time fluoroscopic visualization.

RESULTS: One hundred eighty-two TEIs were performed. Fifty-six cases (30.8%) showed intravascular spreading patterns, 45 cases occurring during a cervical TEI (CTEI) and 11 during a LTEI. The incidences of simultaneous perineural and vascular injection in cervical and LTEIs were 52.1% and 9%, respectively, and pure vascular flow pattern rates in cervical and LTEIs were 11.3% and 0.9%, respectively.

CONCLUSION: The incidence of vascular injection in CTEIs is significantly higher than in LTEIs, suggesting that CTEIs should be performed more cautiously. Furthermore, the vascular injection rate of CTEIs is much higher than that previously reported. This finding suggests the need for a proper volume of contrast injection (3 mL) to detect vascular flow, especially in simultaneous perineural and vascular injections.

Summary: We have developed a web server for the high-throughput annotation of expressed sequence tags (ESTs) called pipeline for EST analysis service (PESTAS). PESTAS processes entire datasets with an automated pipeline of 13 analytic services, then deposits the data into the MySQL database and transforms it into three kinds of reports: preprocessing, assembling and annotation. All annotated information is provided to the scientist and can be downloaded through a web browser. To get more relevant functional annotation results, a curation function was introduced with which biologists can easily change the best-hit annotation information. We included a gene chip module that detects gene expression differences between libraries by comparing accession number counts from BLAST search results. PESTAS also provides access to the pathway information of KEGG, which is useful for mapping the relationships among networks of annotated enzymes, and is especially valuable for those researchers interested in biological pathways.

Dasatinib is the most potent BCR-ABL inhibitor, with 325-fold higher potency than imatinib against unmutated BCR-ABL in vitro. Studies have demonstrated the benefits of dasatinib 70 mg twice daily in patients with accelerated-phase chronic myeloid leukemia intolerant or resistant to imatinib. A phase 3 study compared the efficacy and safety of dasatinib 140 mg once daily with the current twice-daily regimen. Here, results from the subgroup with accelerated-phase chronic myeloid leukemia (n = 317) with a median follow-up of 15 months (treatment duration, 0.03-31.15 months) are reported. Among patients randomized to once-daily (n = 158) or twice-daily (n = 159) treatment, rates of major hematologic and cytogenetic responses were comparable (major hematologic response, 66% vs 68%; major cytogenetic response, 39% vs 43%, respectively). Estimated progression-free survival rates at 24 months were 51% and 55%, whereas overall survival rates were 63% versus 72%. Once-daily treatment was associated with an improved safety profile. In particular, significantly fewer patients in the once-daily group experienced a pleural effusion (all grades, 20% vs 39% P < .001). These results demonstrate that dasatinib 140 mg once daily has similar efficacy to dasatinib 70 mg twice daily but with an improved safety profile. This trial is registered at as #CA180-035.

Background: Meniscus allograft transplantation (MAT) is useful for meniscus-deficient knees. Although meniscal extrusion is common after MAT, there is no consensus regarding the criteria for normal meniscal extrusion or the relationship between clinical and radiologic results.

Hypothesis: Meniscal extrusion after MAT results in poor clinical, radiologic, and arthroscopic outcomes.

Study Design: Case series; Level of evidence, 4.

Methods: Thirty-six of 60 patients undergoing MAT from September 2002 to June 2007 who were available for follow-up evaluation for more than 2 years were evaluated. The study population (31 men, 5 women) consisted of 15 and 21 cases of medial and lateral meniscus transplant, respectively. Knee status was evaluated by Lysholm score, plain radiography, and magnetic resonance imaging preoperatively and postoperatively. Second-look examinations were performed in 18 cases.

Results: Mean follow-up was 31.4 months (range, 24-36). Lysholm knee score increased significantly (mean, 88.2; range, 70-100) on final visit versus the preoperative value (mean, 61.2; range, 26-83; P < .001). Joint-space narrowing was 0.08 mm (range, –2.58 to 1.92) in extension AP and –0.09 mm (range, –2.3 to 1.8) in Rosenberg view. Kellgren-Lawrence arthrosis grade did not change in 28 knees (77.8%) and progressed by 1 grade in 8 knees. Meniscal extrusion extent was 3.87 ± 1.94 mm and relative percentage extrusion was 42.1% ± 17.7%. Seven cases (19.4%) showed minor extrusion (<3 mm), 27 (75%) showed major extrusion (>3 mm), and 2 (5.6%) showed no extrusion. Further degeneration was absent in 28 knees (77.8%) on magnetic resonance imaging. In second-look arthroscopic examinations at an average of 26.3 months, 11 of 18 (63.6%) cases showed no progression of cartilage degeneration. There was no significant correlation between meniscal extrusion and other parameters.

Conclusion: This study indicated that MAT can improve the clinical status of the meniscectomized knee. Although meniscal extrusion occurred after surgery in most cases, there was no significant correlation with various clinical, radiologic, or arthroscopic outcomes. Further studies are required to evaluate long-term effects of meniscal extrusion.
