Purpose: The objective of this systematic review was to characterise the methodological issues, as well as clinical, diagnosis, microbiological and treatment characteristics of patients with spinal tuberculosis., Methods: We conducted a systematic review including prospective or retrospective case series written in English, Spanish, French, German and Italian published in the period from January 1980 to March 2011., Results: Thirty-seven articles were included with a total of 1,997 patients; the median of the percentage of men was 53% (interquartile range [IQR] 48-64) and the median of the patients mean age was 43.4 (IQR 37-55). The most common symptom reported was back pain, and thoracic spine was the most frequent segment involved. Spinal plain radiography was done in 35 studies (94.6%), magnetic resonance imaging (MRI) in 26 (70.2%), computed tomography scan (CT-scan) in 13 (35%) and microbiological diagnosis in 29 (78.3%). Surgical treatment was reported in 28 articles 75.7%; finally, 24 articles reported follow-up, and in 15 of them at least 80% of patients improved., Conclusions: Spinal TB is still an important public health issue, it must be suspected in the presence of back pain or characteristic images and should be confirmed with microbiological procedures. Chemotherapy treatment is often used; in contrast, there is heterogeneity in the percentage of patients treated by surgery.

Background and Objective: Shunt-related infection is a major complication. The effort to face up to this problem has focused on therapy, analysis of risk factors and primary prevention. The aim of this study is to identify risk factors for cerebrospinal fluid shunt infection., Material and Method: We retrospectively reviewed all patients who underwent shunt placement at our hospital during the period of study. Procedures followed for less than 90 days were excluded. One hundred and nineteen procedures were included in the final analysis., Results: Infection rate per procedure was 8.4%. Previous cerebrospinal fluid infection, previous shunt and complete substitution of the shunt were identified as risk factors for infection in the univariate analysis. However, a multivariate analysis confirmed that previous cerebrospinal fluid infection was the only independent risk factor for shunt-related infection (p=0.011)., Conclusion: Previous cerebrospinal fluid infection is an independent risk factor for shunt-related infection. Other factors such as age, gender, etiology of hydrocephalus, previous shunt or complete substitution of the shunt were not associated with increased risk of infection., (Copyright © 2010 Elsevier España, S.L.
