Decompression Alone vs Decompression and Fusion: Spin in Abstracts of Systematic Reviews and Meta-Analysis.

STUDY DESIGN: Cross-sectional. OBJECTIVES: Spin, a prevalent bias, can distort outcomes in well-validated research. Treatment of lumbar stenosis with spondylolisthesis through decompression alone (DA) vs decompression and fusion (DF) remains a controversial topic. We aimed to identify the prevalence of spin in meta-analyses and systematic reviews regarding DA vs DF in the treatment of spinal stenosis with concomitant degenerative spondylolisthesis. METHODS: MEDLINE, Web of Science, and Google Scholar were searched for meta-analyses and systematic reviews comparing DA vs DF treatment of lumbar spinal stenosis accompanied by degenerative spondylolisthesis. Each study was evaluated for the nine most severe spin types. We also explored the association between spin and methodological quality of a systematic review using the revised A Measurement Tool to Assess Systematic Reviews appraisal tool. RESULTS: The search yielded 1506 articles, of which 13 met inclusion. It was found that 46.2% (6/13) of the articles contained spin within the abstract. Of the nine most severe types, type 5 was found to be the most prevalent (4/13, 30.8%), followed by types 9 (2/13, 15.4%), 3 (1/13, 7.7%), 4 (1/13, 7.7%), and 6 (1/13, 7.7%). Spin types 1, 2, 7 and 8 were not found. According to AMSTAR-2, 53.8% (7/13) of the studies were appraised as "critically low" quality and 46.2% (6/13) as "low" quality. CONCLUSION: This study demonstrated the presence of spin in 46.2% of abstracts pertaining to the treatment for spinal stenosis with degenerative spondylolisthesis. Spine surgeons should learn to recognize spin as they review articles before implementing them into practice.

Intraperitoneal hemorrhage secondary to ruptured omental artery aneurysm associated with polyarteritis nodosa: a case report.

BACKGROUND: Polyarteritis nodsa (PAN) is a rare disease characterized by acute focal inflammatory damage to small and medium arteries. PAN complicated by ruptured aneurysm is an infrequent presentation with the most affected arteries being the renal and mesenteric arteries. CASE PRESENTATION: A 76-year-old female presented with a low-grade fever, generalized body aches, and abdominal pain. Investigation revealed intraperitoneal bleeding secondary to a ruptured and actively bleeding right omental artery aneurysm. Clinical manifestation, angiography and histology were consistent with PAN. Laparotomy was performed for stabilization and resection of the bleeding aneurysm followed by post operative steroids and cyclophosphamide. Patient was discharged in a stable condition. We reviewed seven cases found in the literature of omental artery aneurysm and rupture. Four cases were proceeded with laparotomy and aneurysm resection while three cases were proceeded with a less invasive approach of arterial embolization. CONCLUSIONS: Omental artery aneurysm is a rare occurrence with even fewer reported cases associated with PAN. Of the seven reported cases, all patients were treated with a surgical intervention. In addition, PAN patients should be treated post-operatively with a course of steroids and cyclophosphamide.

Cutis Calcinosis of the Hand in 2 Patients With Symbrachydactyly.

Cutis calcinosis of the hand in the setting of symbrachydactyly is presented in 2 unique patients. Both lesions were treated based on the standard of care protocols with resection of the calcified mass and hand reconstruction, as appropriate. The patients healed uneventfully without recurrence of the calcification at a the 1-year follow-up. The association between symbrachydactyly and calcinosis cutis is discussed along with a hypothesis on the pathophysiologic mechanism that could potentially explain this unusual occurrence and why it might be more common than previously identified.

Awake spine surgery: An eye-opening movement.

BACKGROUND: Awake surgery is performed in multiple surgical specialties, but historically, awake surgery in the field of neurosurgery was limited to craniotomies. Over the past two decades, spinal surgeons have pushed for techniques that only require regional anesthesia as they may provide reduced financial burdens on patients, faster recovery times, and better outcomes. The list of awake spine surgeries that have been found in the literature include: laminectomies/discectomies, anterior cervical discectomy and fusions (ACDFs), lumbar fusions, and dorsal column (DC) stimulator placement. METHODS: An extensive review of the published literature was conducted through PubMed database with articles containing the search term "awake spine surgery." No date restrictions were used. RESULTS: The search yielded 293 related articles. Cross-checking of articles was conducted to exclude of duplicate articles. The articles were screened for their full text and English language availability. We finalized those articles pertaining to the topic. Findings have shown that lumbar laminectomies performed with local anesthesia have shown shorter operating time, less postoperative nausea, lower incidence of urinary retention and spinal headache, and shorter hospital stays when compared to those performed under general anesthesia. Lumbar fusions with local anesthesia showed similar outcomes as patients reported better postoperative function and fewer side effects of general anesthesia. DC stimulator placement performed with local anesthesia is advantageous as it allows real time patient feedback for surgeons as they directly test affected nerves. However, spontaneous movement during the placement of DC stimulators is associated with higher failure rates when compared to general anesthesia (29.7% vs. 14.9%). Studies have shown that the use of local anesthesia during ACDFs has no significant differences when compared to general anesthesia, and patient's report better tolerated pain with general anesthesia. CONCLUSION: The use of awake spine surgery is beneficial for those who cannot undergo general anesthesia. However, it is limited to patients who can tolerate prone positioning with no central airway (i.e., normal BMI with a healthy airway), have no pre-existing mental health conditions (e.g., anxiety), and require a minimally invasive procedure with a short operating time. Future studies should focus on long-term efficacies of these procedures that provide further insight on the indications and limitations of awake spine surgery.

Intercostal Hernia due to Forceful Coughing With Protrusion of the Lung.

Intercostal herniation is an abnormal protrusion of lung tissue through the boundaries of the thoracic cavity. It is commonly seen after chest trauma or thoracic surgery but rarely occurs spontaneously. We report a male patient who presented with an intercostal herniation after vigorous coughing for over 2 weeks. Treatment of post-coughing intercostal hernias is either conservative management or surgical intervention, which is dictated by the signs, symptoms, site, and presence of strangulation.

Treatment of Chylothorax After Coronary Artery Bypass Grafting.

Chylothorax after coronary artery bypass grafting is a rare complication. The treatment protocol is not well described because of its rarity. The current treatment options for chylothorax include conservative medical treatment or an interventional approach (ie, thoracic duct embolization or surgical ligation of the thoracic duct). With high chest tube output, medical treatment has a high failure rate, and early embolization or surgical ligation of the thoracic duct should be considered to reduce hospital stay cost and morbidity. This report presents 2 cases of chylothorax after coronary artery bypass grafting with different treatment approaches.

Cellular transplantation and platelet-rich plasma injections for discogenic pain: a contemporary review.

Degenerative disc disease (DDD) is the leading cause of chronic back pain. It is a pathologic condition associated with aging and is believed to result from catabolic excess in the intervertebral discs' (IVD) extracellular matrix. Two new treatment options are intradiscal cellular transplantation and growth factor therapy. Recent investigations on the use of these therapies are discussed and compared with emerging evidence supporting novel cellular injections. At present, human and animal studies provide a compelling rationale for the use of cellular injections in the treatment of discogenic pain. Since DDD results from the IVD extracellular matrix's unmitigated catabolism, cellular injections are used to induce regeneration and homeostasis in the IVD. Here, we review intervertebral disc anatomy, DDD pathophysiology and clinical considerations, as well as the current and emerging literature investigating outcomes associated with cellular transplantation and platelet-rich plasma for discogenic pain. Further high-quality trials are certainly warranted.
