The spinal column is involved in less than 1% of all cases of tuberculosis (TB). Spinal TB is a very dangerous type of skeletal TB as it can be associated with neurologic deficit due to compression of adjacent neural structures and significant spinal deformity. Therefore, early diagnosis and management of spinal TB has special importance in preventing these serious complications. In order to extract current trends in diagnosis and medical or surgical treatment of spinal TB we performed a narrative review with analysis of all the articles available for us which were published between 1990 and 2011. Althoug h the development of more accurate imaging modalities such as magnetic resonance imaging and advanced surgical techniques have made the early diagnosis and management of spinal TB much easier, these are still very challenging topics. In this review we aim to discuss the diagnosis and management of spinal TB based on studies with acceptable design, clearly explained results and justifiable conclusions.

Primary brain and other central nervous system (CNS) cancers cause major burdens. In this study, we introduced a measure named the Quality of Care Index (QCI), which indirectly evaluates the quality of care given to patients with this group of cancers. Here we aimed to compare different geographic and socioeconomic patterns of CNS cancer care according to the novel measure introduced. In this regard, we acquired age-standardized primary epidemiologic measures were acquired from the Global Burden of Disease (GBD) study 1990-2017. The primary measures were combined to make four secondary indices which all of them indirectly show the quality of care given to patients. Principal Component Analysis (PCA) method was utilized to calculate the essential component named QCI. Further analyses were made based on QCI to assess the quality of care globally, regionally, and nationally (with a scale of 0-100 which higher values represent better quality of care). For 2017, the global calculated QCI was 55.0. QCI showed a desirable condition in higher socio-demographic index (SDI) quintiles. Oppositely, low SDI quintile countries (7.7) had critically worse care quality. Western Pacific Region with the highest (76.9) and African Region with the lowest QCIs (9.9) were the two WHO regions extremes. Singapore was the country with the maximum QCI of 100, followed by Japan (99.9) and South Korea (98.9). In contrast, Swaziland (2.5), Lesotho (3.5), and Vanuatu (3.9) were countries with the worse condition. While the quality of care for most regions was desirable, regions with economic constraints showed to have poor quality of care and require enforcements toward this lethal diagnosis.

BackgroundThe incidence of transient neurologic symptoms (TNS) after spinal anesthesia with lidocaine is reported as high as 40%.ObjectivesThis prospective clinical trial was designed to determine the incidence of TNS in patients who underwent spinal anesthesia with two different needles, in two different surgical positions.Patients and MethodsThe present randomized clinical trial was conducted on 250 patients (ASA I-II), who were candidates for surgery in supine or lithotomy positions. According to the needle type (Sprotte or Quincke) and local anesthetics (lidocaine and bupivacaine) all patients were randomly divided into four groups. After performing spinal anesthesia in sitting position, the position was changed into supine or lithotomy, according to surgical procedure. The patients were observed for complications of spinal anesthesia during the first five post-operative days. The primary end-point for this trial was to recognize the incidence of TNS among the four groups. Our secondary objective was to evaluate the effect of patient's position, needle type, and duration of surgery on the development of TNS following spinal anesthesia.ResultsTNS was most commonly observed when lidocaine was used as anesthetic drug (P = 0.003). The impact of needle type, was not significant (P = 0.7). According to multivariate analysis, the duration of surgery was significantly lower in cases suffering from TNS (P = 0.04). Also, the risk of TNS increased following surgeries performed in lithotomy position (P = 0.00).ConclusionsAccording to the results of this clinical study, spinal anesthesia with lidocaine, and the lithotomy position in surgery increased the risk of TNS.

Background:Postoperative infection is one of the most common complications after spine surgeries. In our study, surgical site infection (SSI) is described as; superficial (i.e., skin and subcutaneous tissues) and deep (i.e., fascia and muscles) infections occurring in the short term (i.e., 1-month) after spine surgeries (Centers for Disease Control and Prevention definition 81.00–81.08). To detect the risk factors for the occurrence of such a complication, studies require a large number of patients, a high quality of data and adequate analysis. In this study, we prospectively enrolled 987 patients undergoing spinal surgery over a 3 years period.Methods:From November 2010 to November 2013, 987 patients had a variety of spinal operations that included; disc herniation, spinal stenosis, spondylolisthesis, fracture-dislocations, spine and spinal cord tumors, and syringomyelia. Patients under the age of 10, those with a recent history of infection and antibiotherapy, and patients with immunodeficiency disorders were excluded.Results:Of the 987 spine procedures performed, 27 (2.73%) developed postoperative infections. Multi-variant data analysis indicated that multiple factors correlated with an increased risk of SSI in descending order; trauma, a past history of diabetes, smoking, being confined to bed, in the perioperative period, mean blood sugar levels above 120 mg/dl, longer lengths of incisions, and longer hospital stay.Conclusion:Considering the preventable nature of most of the factors contributing to SSI, it should be possible to reduce these complications.

PurposeThere are some studies which showed neurofeedback therapy (NFT) can be effective in clients with traumatic brain injury (TBI) history. However, randomized controlled clinical trials are still needed for evaluation of this treatment as a standard option. This preliminary study was aimed to evaluate the effect of NFT on continuous attention (CA) and short-term memory (STM) of clients with moderate TBI using a randomized controlled clinical trial (RCT).MethodsIn this preliminary RCT, seventeen eligible patients with moderate TBI were randomly allocated in two intervention and control groups. All the patients were evaluated for CA and STM using the visual continuous attention test and Wechsler memory scale-4th edition (WMS-IV) test, respectively, both at the time of inclusion to the project and four weeks later. The intervention group participated in 20 sessions of NFT through the first four weeks. Conversely, the control group participated in the same NF sessions from the fifth week to eighth week of the project.ResultsEight subjects in the intervention group and five subjects in the control group completed the study. The mean and standard deviation of participants' age were (26.75 ± 15.16) years and (27.60 ± 8.17) years in experiment and control groups, respectively. All of the subjects were male. No significant improvement was observed in any variables of the visual continuous attention test and WMS-IV test between two groups (p ≥ 0.05).ConclusionBased on our literature review, it seems that our study is the only study performed on the effect of NFT on TBI patients with control group. NFT has no effect on CA and STM in patients with moderate TBI. More RCTs with large sample sizes, more sessions of treatment, longer time of follow-up and different protocols are recommended.

BackgroundRecently, several studies have been conducted to determine the optimal strategy for intra-operative fluid replacement therapy in renal transplantation surgery. Since infusion of sodium bicarbonate as a buffer seems to be safer than other buffer compounds (lactate, gluconate, acetate)that indirectly convert into it within the liver, We hypothesized tight control of metabolic acidosis by infusion of sodium bicarbonate may improve early post-operative renal function in renal transplant recipients.Methods120 patients were randomly divided into two equal groups. In group A, bicarbonate was infused intra-operatively according to Base Excess (BE) measurements to achieve the normal values of BE (−5 to +5 mEq/L). In group B, infusion of bicarbonate was allowed only in case of severe metabolic acidosis (BE ≤ −15 mEq/L or bicarbonate ≤ 10 mEq/L or PH ≤ 7.15). Minute ventilation was adjusted to keep PaCO2 within the normal range. Primary end-point was sampling of serum creatinine level in first, second, third and seventh post-operative days for statistical comparison between groups. Secondary objectives were comparison of cumulative urine volumes in the first 24 h of post-operative period and serum BUN levels which were obtained in first, second, third and seventh post-operative days.ResultsIn group A, all of consecutive serum creatinine levels were significantly lower in comparison with group B. With regard to secondary outcomes, no significant difference between groups was observed.ConclusionIntra-operative tight control of metabolic acidosis by infusion of Sodium Bicarbonate in renal transplant recipients may improve early post-operative renal function.

Study Design:A total of 110 patients with scoliosis were enrolled in this analytical cross-sectional study. Purpose: We aimed to compare the urodynamic study (UDS) results of patients with idiopathic scoliosis (ISC) and congenital scoliosis (CSC) and to evaluate the clinical significance of abnormal UDS findings in predicting underlying tethered cord syndrome (TCS). Overview of Literature: An abnormal UDS finding is commonly found in patients with CSC. However, there is no consensus regarding its prevalence in patients with ISC. Methods: Using the STROBE checklist for cross-sectional studies, 110 patients with scoliosis were selected based on our inclusion and exclusion criteria. Among the patients, 76 presented with ISC and 34 with CSC. Demographic data and other details, such as the results of spine radiography, UDS, and magnetic resonance imaging of the spine in both supine and prone positions, were recorded and analyzed. Results: Approximately 50% of patients with CSC had normal UDS findings; 8.8%, mild impairment; and 41.2%, significant abnormalities. Moreover, 67.1% of patients with ISC had normal UDS findings; 9.2%, mild impairment; and 23.7%, significant abnormalities (p=0.166). TCS was identified in 38.2% and 26.3% of patients with CSC and ISC, respectively (p=0.571). In patients with ISC, a significantly abnormal UDS finding indicated that the risk of TCS increased from 26.3% to 50% (odds ratio [OR], 4.2; p=0.009). Meanwhile, in patients with CSC, the risk was almost similar (OR, 0.8; p=0.8). Conclusions:Even with the absence of subjective urinary symptoms, subclinical urologic impairments can be observed in a significant number of patients with ISC. An abnormal UDS finding can be a sign of underlying spinal cord tethering in a patient with ISC who is a candidate for corrective spine surgery even though it is an independent variant and is not exclusive to candidates for surgery. This finding has high clinical utility for neuro-and ortho-spine surgeons who aim to correct scoliosis (OR, 4.2; p=0.009).

Background and Objectives: Stabbing the head is a rare event. It may occur following an assault or self-inflicted injury. We intend to report our experience with four such cases and review narratively the relevant literature. A treatment algorithm will be delivered. Materials and Methods: We have reviewed four of our cases; three were stabbed to the orbit and one to the head. Results: Enucleation was performed in one case. Vision could be preserved in the other two and brain abscess developed in the other cases due to a retained piece of knife. We made a comparison between our cases and those limited reports in the literature to reach an algorithm. Conclusion: The temporal region and the orbit are the targets mostly attacked in the craniofacial stabs. Since knives have a sharp and thin edge, they may break when penetrating the skull. The damage to the brain tissue and the retained piece of knife may be missed easily by overlooking the small injury to the scalp. The suggested algorithm would be a contrast-enhanced computed tomography scan of the skull and brain and a kind of brain vascular study are necessary, considering the location of the knife in the skull and brain passing the area with crowded vasculature. The best treatment protocol is surgery accompanied by antibiotic therapy.
