Vertebral arteriovenous fistula due to blunt neck trauma: A case report.

The arteriovenous fistulas (AVFs) of the vertebral artery are usually caused by iatrogenic and penetrating traumas. Vertebral AVF is rarely seen after blunt cervical trauma. A 65-year-old male patient applied to the emergency clinic due to falling from a height of about 3 m. In his neurological examination, he had weakness in the left upper limb and tinnitus in the left ear. The cervical computed tomog-raphy examination showed a Hangman's fracture, a C3 vertebra corpus compression fracture, and a C1 anterior arch fracture. There was a separation on the C1-2 transverse foramen due to the fracture, and there was a fracture in the left C3-4 transverse foramen. In cervical magnetic resonance imaging (MRI), the presence of a contusion in the spinal cord at the C2 corpus level was observed. Through an MRI angiography examination of the vertebral artery, it was determined that the left vertebral artery had developed an AVF at the V2-3 segment level. Stabilization surgery was performed with a posterior approach for unstable vertebrae. Then, vertebral AVF was then closed endovascularly using a stent coil. Improvement in neurological deficit was seen after surgery and endovascular treatment. There were no complications related to the procedure. Transverse foramen should be carefully evaluated, especially in the upper cervical trauma. Vertebral artery imaging should be performed before instability surgery in the presence of a separation in the fracture line to determine whether the damage to the vertebral artery is iatrogenic.

Influence of galantamine on peripheral nerve degeneration after experimental compression injury of the rat sciatic nerve.

BACKGROUND: Galantamine is well-known for its neuroprotective effects and is currently used in the treatment of individuals with Alzheimer's disease. In this study, we induced experimental sciatic nerve injury (SCI) in rats to test the beneficial effects of galantamine. METHODS: Thirty male Wistar albino rats were divided into three groups, as follows: sham, SCI + saline, and SCI + galantamine. After the administration of an intraperitoneal ketamine and xylazine mixture, which was used for anesthesia, SCI was induced by sur-gical clip compression at the midthigh region of the rats. After surgery, a single daily intraperitoneal dose of galantamine was adminis-tered for 7 days, and nerve tissue sections were obtained 1 week after injury. Histopathology studies were performed to assess neural thickness and apoptotic cell counts, and light microscopic morphological examination was used to determine a potential beneficial effect of galantamine on peripheral nerve degeneration. RESULTS: We observed a markedly increased microvasculature, increased nerve fiber thickness, and a statistically significant increase in apoptotic cell counts distal to the level of injury in the saline group compared with the sham group. However, the increases in nerve fiber thickness and apoptotic cell counts were less in the galantamine group compared with the saline group. CONCLUSION: In our experimental model, pharmacological intervention with galantamine demonstrated a protective effect on degeneration after peripheral nerve injury.

Factors Affecting the Intensive Care Stay of Patients with Spinal Neural Tube Defects.

AIM: To evaluate the duration of hospitalization and the factors that increase this duration in cases treated in the neonatal intensive care unit with the diagnosis of a spinal neural tube defect (NTD). MATERIAL AND METHODS: The demographic characteristics, NTD type and level, ventriculoperitoneal (V-P) shunt needs, accompanying spinal deformity, antibiotherapy applied during treatment, and intensive care stay periods of 73 patients treated in our clinic between July 2017 and 2020 were retrospectively evaluated. RESULTS: The intensive care stay of NTD cases was 7?109 (mean=23) days. Fifty-one cases (69.9%) had myeloschisis, and 22 cases (30.1%) had myelomeningocele (MMC) sac. A V-P shunt was applied to 24 cases (32.9%) during hospitalization, and additional antibiotherapy was given to 32 (43.8%) cases. CONCLUSION: In myeloschisis cases compared with MMC marsupial cases, incidences of ventricular dilatation, kyphotic/scoliotic spine pathology, V-P shunt requirement, and longer hospital stay were observed. No difference in the duration of hospitalization was found in patients who underwent defect repair between the first day and 48 h after birth. However, the length of stay in hospital increased in patients operated on after 48 h. The period was longer in cases operated after seven days postnatally. Therefore, by performing NTD surgical treatment within the first 48 hours, the need for additional antibiotherapy and hospital stay can be shortened.

Clinical Results of Unilateral Dynamic Rod Application in the Short-Medium Period.

AIM: To evaluate the clinical results of patients who underwent unilateral dynamic rod stabilization after unilateral facet joint excision during spinal surgery. MATERIAL AND METHODS: Twenty patients who were diagnosed with degenerative spinal disease or spinal tumor, who were operated on using a unilateral approach, who underwent facet joint resection, and who were stabilized with a unilateral dynamic rod were examined. Visual analog scale (VAS) and Oswestry disability index (ODI) scores were used to clinically evaluate the cases during the preoperative and postoperative periods. Radiological examinations for sagittal alignment, segmental angle, and bone fusion were also conducted. RESULTS: The mean preoperative VAS and ODI scores were 7.6 and 71.7, respectively, and the 12 < sup > th < /sup > postoperative month scores were 1.1 and 12.8, respectively. The mean segmental angle measurements were 22.1° in the preoperative period and 21.6° at the postoperative 12 < sup > th < /sup > month. No deterioration in sagittal alignment and no bone fusion were observed. CONCLUSION: We can protect segmental movements and provide sufficient stability by applying unilateral dynamic rod stabilization after unilateral facetectomy. In addition, applying screws to one side can reduce operation time and cost as well as the possibility of complications.

The Effect of the COVID-19 Pandemic on Functioning of Neurosurgery Clinics and the Anxiety Levels of Neurosurgeons in Turkey.

AIM: To reveal the impacts of the novel coronavirus 2019 (COVID-19) pandemic on the functioning of neurosurgery clinics and to determine the anxiety levels and attitudes of Turkish neurosurgeons towards their profession during the pandemic. MATERIAL AND METHODS: The Beck anxiety inventory and a clinical activities scale were utilized as data collection tools and distributed to neurosurgeons in Turkey as an online survey. Descriptive statistical methods, significance tests and correlation and regression analyses were employed to analyze the data. The data analysis was carried out in a 95% confidence interval. RESULTS: Of the 240 neurosurgeons who participated in the study, 63.8% had encountered cases of COVID-19 and 53.8% had handled patients diagnosed with COVID-19. The study results showed that the pandemic did not cause anxiety in 62.9% of the respondents, but it caused mild anxiety in 13.8% and moderate anxiety in 12.12%. The findings also revealed a low linear correlation between the anxiety values and occupational anxiety of the neurosurgeons and low inverse correlation between anxiety values and the protection factor in the pandemic period. CONCLUSION: The COVID-19 pandemic has caused serious disruptions in the routine functioning of neurosurgery clinics and changes in the attitudes of neurosurgeons. Healthcare organizations should take the necessary precautions and measures to resolve the anxiety problems of healthcare professionals, such as providing professional support, and ensure that they can work in a safer environment.

Late-Onset Tethered Cord Syndrome in a Patient with Spina Bifida: A Case Report.

Tethered cord is a clinical syndrome associated with short and thick filum terminale. It can occur because of congenital or acquired reasons and can lead to progressive neurological deficits. A thorough medical history, physcial examination, imaging, and electrophysiological tests are heplful in its diagnosis. An 11-year-old patient with a prior diagnosis of spina bifida was operated for pes ekinovarus at the age of 1.5 years. The patient visited our physical medicine and rehabilitation polyclinic with complaints of pain and weakness in the left ankle and region around the knee. She had been suffering from walking disruption, thinning of leg muscles, and pain for past 1 year. After imaging, a diagnosis of tethered cord syndrome was made. Follow-up of patients diagnosed with spina bifida during growth period is important to prevent complications such as syringomyelia and tethered cord syndrome.

Anti-edematous, anti-inflammatory and neuroprotective effect of etanercept in acute stage in experimental head injury.

BACKGROUND: To study the anti-edematous, anti-inflammatory, and neuroprotective effect of etanercept in the model of experimental head injury. METHODS: In this study, 40 male-adult Spraque-Dawley rats, with weight ranging from 250g to 300g, were used. The rats are divided into groups as control; non-penetrating trauma; trauma +NS; post-traumatic normal saline; trauma + D; post-traumatic dexamethasone and trauma + E. All medicines were given into peritoneum. After applying trauma and medicine, rats were decapitated in the 24th hour and the samples were studied histopathologically. RESULTS: In the study, a statistically significant difference was observed between the groups of trauma + NS and trauma dexamethasone according to the variables of edema and inflammation, but no difference was observed according to the variables of neuronal damage, astrocytic damage, and glial apoptosis. Moreover, a significant difference was observed between groups of Trauma + NS and trauma+etanercept and between the groups of trauma + dexamethasone and trauma + etanercept in terms of all variables. CONCLUSION: It was observed that etanercept has anti-edematous, anti-inflammatory, and neuroprotective effect on the rats which experienced traumatic brain injury.

Isokinetic evaluation of wrist muscle strength in patients of carpal tunnel syndrome.

OBJECTIVES: This study aims to investigate the isokinetic characteristics of wrist strength in flexion, extension, supination, pronation, radial, and ulnar deviation in patients with moderate or severe carpal tunnel syndrome (CTS). PATIENTS AND METHODS: Thirteen patients (23 hands) (2 males, 11 females; mean age 45 years; range 29 to 60 years) with moderate or severe CTS were compared to six healthy control subjects (12 hands) (2 males, 4 females; mean age 41 years; range 27 to 63 years) in this study, which was conducted between January 2016 and April 2016. Wrist flexion, extension, supination, pronation, radial, and ulnar deviation muscle strengths were measured at 30°/second (5 sets) angular velocity with isokinetic dynamometer. Grip strength was measured with hand dynamometer (kilograms). Boston Questionnaire was used for clinical assessment. RESULTS: Grip strength (p=0.003); wrist flexion 30°/second (p=0.014); extension 30°/second (p=0.016); and ulnar deviation 30°/second (p=0.017) muscle strengths were lower in CTS patients compared with the control group. An evaluation according to symptom duration did not reveal any significant relationship in any of the isokinetic tests with the exception of pronation 30°/second (p=0.039, r= -0.432) and ulnar deviation 30°/second (p=0.034, r=0.443) in CTS patients. No significant relationship was found between Boston Questionnaire, grip strength, and isokinetic test results. CONCLUSION: Quantitative wrist strength measurements with isokinetic dynamometers are beneficial in conservative exercise treatments and motor assessments of CTS patients.

The relationships of motor-evoked potentials to hand dexterity, motor function, and spasticity in chronic stroke patients: a transcranial magnetic stimulation study.

The standardization of patient evaluation and monitoring methods has a special importance in evaluating the effectiveness of therapeutic methods using drugs or rehabilitative techniques in stroke rehabilitation. The aim of this study was to investigate the relationships between clinical instruments and transcranial magnetic stimulation (TMS)-evoked neurophysiological parameters in stroke patients. This study included 22 chronic post-stroke patients who were clinically assessed using the Motricity Index (MI), finger-tapping test (FTT), Motor Activity Log (MAL) 28, Brunnstrom motor staging and Ashworth Scale (ASH). Motor-evoked potential (MEP) latency and amplitude, resting motor threshold (rMT) and central motor conduction time (CMCT) were measured with TMS. Shorter MEP-latency, shorter CMCT, higher motor-evoked potential amplitude, and diminished rMT exhibited significant correlations with clinical measures evaluating motor stage, dexterity, and daily life functionality. rMT exhibited a negative correlation with hand and lower extremity Brunnstrom stages (r = -0.64, r = -0.51, respectively), MI score (r = -0.48), FTT score (r = -0.69), and also with amount of use scale and quality of movement scale of MAL 28 scores (r = -0.61, r = -0.62, respectively). Higher MEP amplitude and diminished rMT showed positive correlations with reduced ASH score (r = -0.65, r = 0.44, respectively). The TMS-evoked neurophysiologic parameters including MEP latency, amplitude, rMT and CMCT generally have positive correlation with clinical measures which evaluate motor stage, dexterity and daily life functionality. Additionally, spasticity has also remarkable relationships with MEP amplitude and rMT. These results suggest that TMS-evoked neurophysiological parameters were useful measures for monitoring post-stroke patients.

Should we continue to administer blind shoulder injections?

OBJECTIVES: This study aims to investigate the accuracy and effectiveness of blind and fluoroscopic-guided intra-articular shoulder injections in patients with shoulder pain. PATIENTS AND METHODS: The study included 17 patients (6 males, 11 females; mean age 52.6±9.9 years; range 36 to 66 years) with shoulder pain more than three months. First intra-articular joint injections were performed with anterior approach blindly. Following the injection and after confirming that the needle tip was intra-articular with fluoroscopy and contrast distribution, the procedure was completed using 3 mL of local anesthetic (prilocaine and bupivacaine) and 1 mL of steroid (40 mg methylprednisolone). When the contrast distribution was observed to be extra-articular at the first administration, a second injection was continued under fluoroscopy guidance. All of the injections were intra-articular with the continuation of the procedure. Pain intensity was measured with visual analog scale (VAS). RESULTS: According to the contrast distribution viewed with fluoroscopy, first blind injections were intra-articular in 11 of the 17 shoulders (64.7%). Mean of initial VAS score was 7.11. Improved pain was observed in the clinical follow-ups at the first hour (mean VAS: 2.35), third day (mean VAS: 2.64), and at the end of the first month (mean VAS: 2.23). The mean durations for blind and fluoroscopic-guided procedures excluding patients' preparation time were 0.8 minutes and 4.2 minutes, respectively. CONCLUSION: Although blind intra-articular shoulder injections are inexpensive and easily applicable, injections should be performed under fluoroscopy or another guide to ensure that the needle is intra-articular, not peri-articular.

Correlations among enthesitis, clinical, radiographic and quality of life parameters in patients with ankylosing spondylitis.

OBJECTIVES: To investigate the relationship between enthesitis and disease activity, functional status, fatigue, joint mobility, radiological damage, laboratory parameter and quality of life in patients with ankylosing spondylitis (AS). METHODS: A total of 421 patients with AS (323 male and 98 female) who were included in the Turkish League Against Rheumatism Registry were enrolled in the study. The Bath AS Disease Activity Index (BASDAI), fatigue, the Bath AS Functional Index (BASFI), the Bath AS Metrology Index (BASMI), the Maastricht AS Enthesitis Score (MASES), AS quality of life (ASQoL), the Bath AS Radiology Index (BASRI) and erythrocyte sedimentation rate (ESR) were evaluated. RESULTS: Enthesitis was detected in 27.3% of patients. There were positive correlations between MASES and BASDAI, BASFI and fatigue (p < 0.05). MASES was not correlated with BASRI, BASMI, ASQoL and ESR. The mean MASES score was 1.1 ± 2.4. The most frequent regions of enthesopathies were right iliac crest, spinous process of L5 and proximal to the insertion of left achilles tendon, respectively. CONCLUSIONS: Enthesitis was found to be associated with higher disease activity, higher fatigue, worse functional status and lower disease duration. As enthesitis was correlated with BASDAI, we conclude that enthesitis can reflect the disease activity in patients with AS.

Hepatitis B virus reactivation in a juvenile rheumatoid arthritis patient under treatment and its successful management: a complicated case.

Juvenile rheumatoid arthritis is a common chronic inflammatory disease in the childhood and it can differentiate rarely into spondiloarthropaties. It is one of the important causes of chronic pain and disability. Some of the drugs used for the treatment have immunosupressive activity. One of the serious side-effects of immunosupressive treatment is activation of opportunistic pathogens. Hepatitis B virus (HBV) is one of these pathogens, and the rate of carriers in the population is considerably high. It can cause liver damage and death if reactivated. Thus, the management of oppotunistic pathogens becomes a complex issue when treating rheumatic diseases with immunosupressive drugs. In this case report, we present a juvenile rheumatoid arthritis patient whose liver enzymes raised while he was under treatment and afterwards HBV reactivation was determined as the cause. When reactivation was detected, we started controlled antiviral therapy. We achieved successful clinical and laboratory results after adding biological agents to the treatment. Careful evaluation of the patients who have indication for immunosuppressive agents and regular follow-up in case of infection may be protective from severe morbidity and/or mortality.

Chronic low back pain caused by osteopetrosis type 2.

Causes for low back pain usually involve damages in bone, muscle or nerve tissues of spine. Hereditary sclerosing bone disorders are rarely presented with low back pain. This report is intended to remind that osteopetrosis type 2, which is a rare disorder in differential diagnosis of low back pain, should be taken into consideration.

The effect of dry needling in the treatment of myofascial pain syndrome: a randomized double-blinded placebo-controlled trial.

The objective of this study was to test the hypothesis that dry needling is more effective than sham dry needling in the treatment of myofascial pain syndrome (MPS). This was a prospective, double-blinded, randomized-controlled study conducted in an outpatient clinic. Thirty-nine subjects with established myofascial trigger points were randomized into two groups: study group (N = 22) and placebo group (N = 17). Dry needling was applied using acupuncture needles, and sham dry needling was applied in the placebo group. The treatment was composed of six sessions which were performed in 4 weeks; the first four sessions were performed twice a week (for 2 weeks) and the last two, once a week (for 2 weeks). The visual analog scale (VAS) and Short Form-36 (SF-36) were used. When compared with the initial values, VAS scores of the dry needling group following the first and sixth sessions were significantly lower (p = 0.000 and p < 0.000, respectively). When VAS scores were compared between the groups, the first assessment scores were found to be similar, but the second and third assessment scores were found to be significantly lower in the dry needling group (p = 0.034 and p < 0.001, respectively). When SF-36 scores of the groups were compared, both the physical and mental component scores were found to be significantly increased in the dry needling group, whereas only those of vitality scores were found to be increased significantly in the placebo (sham needling) group. The present study shows that the dry needling treatment is effective in relieving the pain and in improving the quality of life of patients with MPS.
