Objective : Thoracic pedicles have special and specific properties. In particular, upper thoracic pedicles are positioned in craniocaudal plane. Therefore, manipulation of thoracic pedicle screws on the left side is difficult for right-handed surgeons. We recommend a new position to insert thoracic pedicle screw that will be much comfortable for spine surgeons. Methods : We retrospectively reviewed 33 patients who underwent upper thoracic pedicle screw instrumentation. In 15 patients, a total of 110 thoracic pedicle screws were inserted to the upper thoracic spine (T1-6) with classical position (anesthesiologist and monitor were placed near to patient's head. Surgeons were standing classically near to patient's body while patients were lying in prone position). In 18 patients, a total of 88 thoracic pedicle screws were inserted to the upper thoracic spine with the new standing position-surgeons stand by the head of the patient and the anesthesia monitor laterally and under patient's belt level. All the operations performed by the same senior spine surgeons with the help of C-arm. Postoperative computed tomography scans were obtained to assess the screw placement. The screw malposition and pedicle wall violations were divided and evaluated separately. Cortical penetration were measured and graded at either : 1-2 mm penetration, 2-4 mm penetration and >4 mm penetration. Results : Total 198 screws were inserted with two different standing positions. Of 198 screws 110 were in the classical positioning group and 88 were in the new positioning group. Incorrect screw placement was found in 33 screws (16.6%). The difference between total screw malposition by both standing positions were found to be statistically significant (p=0.011). The difference between total pedicle wall violations by both standing positions were found to be statistically significant (p=0.003). Conclusion : Right-handedness is a problem during the upper thoracic pedicle screw placement on the left side. Changing the surgeon's position standing near to patient's head could provide a much comfortable position to orient the craniocaudal plane of the thoracic pedicles.

Background and Objectives: In this study, we examined the role of inflammatory parameters in an apical mural thrombus with a reduced ejection fraction due to large anterior myocardial infarction (MI). Subjects and Methods: A total of 103 patients who had suffered from heart failure, 45 of whom had left ventricular apical thrombus (AT) after a large anterior MI, were enrolled in the study. A detailed clinical history was taken of each participant, biochemical inflammatory markers, which were obtained during admission, were analyzed and an echocardiographical and angiographical evaluation of specific parameters were performed. Results: There were no statistically significant differences in terms of age, gender, and history of hypertension, diabetes mellitus, and atrial fibrillation between both groups (p>0.05). Similarly there were no statistically significant differences in terms of biochemical and echocardiographic parameters (p>0.05). However, there were significant differences in terms of neutrophil lymphocyte ratio (p=0.032). After a multivariate regression analysis, neutrophil lymphocyte ratio (NLR) was an independent predictor of thrombus formation (ß: 0.296, p=0.024). The NLR >2.74 had a 78% sensivity and 61% specifity in predicting thrombus in patients with a low left ventricular ejection fraction. Conclusion: In this study, neutrophil lymphocyte ratios were significantly higher in patients with apical thrombus.

Lumbar Epidural Varix Mimicking Disc Herniation
Bursali, Adem,Akyoldas, Goktug,Guvenal, Ahmet Burak,Yaman, Onur The Korean Neurosurgical Society 2016 Journal of Korean neurosurgical society Vol.59 No.4
Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted as an extruded disc herniation preoperatively was found to be a thrombosed epidural varix compressing the nerve root preoperatively. The nerve root was decompressed by shrinking the lesion with bipolar thermocoagulation and excision. The patient's complaints disappeared in the postoperative period. Thrombosed lumbar epidural varices may mimic lumbar disc herniations both radiologically and clinically. Therefore, must be kept in mind in the differential diagnosis of lumbar disc herniations. Microsurgical techniques are mandatory for the treatment of these pathologies and decompression with thermocoagulation and excision is an efficient method.

ObjectiveHuman papillomaviruses (HPVs) are among the agents responsible for infection and cancer of the skin and mucousmembranes in the human body. The aim of this study was to investigate the frequency and type distribution of HPVsin married female patients with gynecological complaints, who had visited the Maternity Hospital in Erzurum, Turkey. MethodsIn this study, 263 cervical swab samples were taken from married women using the Pap smear method and wereinvestigated for positive reactivity against HPV. The L1 gene region of HPV was investigated using molecular methods. For this purpose, polymerase chain reaction (PCR) assays and sequence analysis of positive samples were performed. Phylogenetic analyses were performed using a bioinformatics approach after sequencing. ResultsHPV-DNA was detected in 17 (6.5%) samples. Highest positive reactivity to HPV-DNA was found in the 35–44 agegroup at 9.2%. Fourteen out of seventeen positive samples were included in the phylogenetic analysis. All isolatesclustered in the Alphapapillomavirus genus. Six samples were found to be HPV 70 positive, four were HPV 16 positive,and the rest were HPV 54, 72, 81, and 114 positive. When genotyping data were evaluated according to the riskgroup, we found that 28.6% of the 14 samples were found to be high risk-HPV, and 71.4% were low risk-HPV. ConclusionAs per our knowledge, this is the first report on the phylogenetic analysis of HPV genotypes isolated from women inTurkey. The prevalence of low- and-high risk HPV was determined in married women in Erzurum, and these resultscontribute to the epidemiological data on the distribution of HPV types for this region.
