Objectives: This study aims to evaluate facet tropism in younger patients with lumbar spondylolysis and to investigate the role of facet tropism in the development of spondylolysis. Patients and methods: Between February 2013 and December 2015, a total of 102 male patients with bilateral L5 pars defect including 53 with spondylolysis and 49 control subjects were included in this case-control study. The facet joint angles were measured bilaterally and axially at the level of L3-4, L4-5, L5-S1 using computed tomography (CT). The classification was made as follows: A difference between two reciprocal facet joint angles of < 6 degrees indicated no tropism, 6 degrees-12 degrees indicated moderate tropism, and > 12 degrees indicated severe tropism. Results: A total of 612 angles including 318 facet joint angles from 53 patients with spondylolysis and 294 facet joint angles from 49 control subjects were measured. L3-4 measurements in the control group showed no tropism in 87.8% (n=43), moderate tropism in 12.2% (n=6), and severe tropism in 0% (n=0). L4-5 measurements in control group showed no tropism in 79.6% (n=39), moderate tropism in 20.4% (n=10), and severe tropism in 0% (n=0). L5-S1 measurements in the control group showed no tropism in 69.4% (n=34), moderate tropism in 28.6% (n=14), and severe tropism in 2.0% (n=1). The mean facet joint angles in the spondylosis group were 32.9 +/- 5.1 degrees, 37.5 +/- 5.4 degrees, and 41.2 +/- 7.8 degrees at the levels of L3-4, L4-5, and L5-S1, respectively. The mean facet joint angles of the control group were 33.2 +/- 5.7 degrees, 39.7 +/- 4.9 degrees, and 42.2 +/- 4.9 degrees at the levels of L3-4, L4-5, and L5-S1, respectively, indicating no significant difference between the right and left mean facet joint angles between the groups (p > 0.05). The frequency of facet tropism and the difference between right and left facet joint angles for all three levels were significantly higher in the spondylolysis group (p < 0.05). Facet tropism at the level of L5-S1 was significantly more frequent than facet tropism at L3-4 level (p < 0.05). Conclusion: Our study results show that the rate of facet joint tropism is higher in the patients with spondylolysis, suggesting that facet tropism seems to play a role in the etiology of spondylolysis as a predisposing factor.

Objective: The purpose of this retrospective study was to investigate nosocomial infections associated with central venous catheter (CVC) in Neurosurgery Intensive Care Unit (NSICU) and to discuss the means of prevention. Material and Methods: The patients who were admitted to Neurosurgery ICU at the GATA Haydarpasa Teaching Hospital between the years of 2008 to 2011 were evaluated for the study. All the patient medical records that were collected at the Hospital Infection Control Committee were screened retrospectively. Of the 426 patients' medical records that were screened, 145 patients with CVC were included in this study. Results: A total of 145 patients who were treated with CVC in NSICU were followed up. Of the 145 patients, 98 were surgically treated for main diagnosis and their CVC was inserted under operation room conditions. The remaining 47 patients were followed up in NSICU and their CVC was inserted in the environment of ICU. Methicillin-resistant coagulase-negative staphylococci (25%, n = 10) was the most commonly isolated agent from the patients with CVC-induced infections, followed by Methicillin-resistant Staphylococcus aureus (16%, n = 4). Conclusion: In this study, the rate of CVC related infection of blood circulation was higher in the patients who underwent surgery and whose catheter was inserted in the operation room. It can be postulated that surgical stress might result immunosuppression that predisposes CVC patients to infections.
Spontaneous Regression of Lumbar Disc Herniation Correlated With Clinical and Radiological Improvement: Case Report
(Journal Neurological Sciences, 2015) Cuce, Ferhat; Eroglu, Ahmet; Eseoglu, Metehan; Atabey, Cem; Deniz, Suleyman; Duz, Bulent
In recent years, the increase in the quality of imaging techniques is for diagnosis of lumbar disc hernia (LDH) accounted facilitate the diagnosis and follow-up an important development. Especially extruded LDH is started to be more frequent. Radicular pain is one of the most important complaints with extruded lumbar disc herniation in patients. Surgery is performed due to radiculopathy In many patients. Spontaneous regression of extruded lumbar disc herniation is a rare condition. In such extruded lumbar disc herniation cases, the contrast-enhanced MRI can give us several predictions associated with the prognosis of herniation. We aimed to present 21 years old male patient a case of regressed and extruded lumbar disc herniation without any surgical intervention, only with neurologic improvement together with radiological findings in light of literature.
