Efficacy and Advantages of Spinal Anesthesia in Lumbar Disk Surgery.

BACKGROUND: Quality of life (QoL) may be affected due to various reasons such as low back or leg pains with accompanying neurologic problems. Lumbar disk surgery is one of the most common performed surgeries to relieve those symptoms. Various anesthetic techniques can be used safely to perform lumbar disk surgeries. Properties that make an anesthetic technique good are mainly the quick onset and returning of the effects. This large retrospective study with patients who have undergone lumbar disk surgery under spinal anesthesia aims to evaluate the perioperative and postoperative parameters of the spinal anesthesia and review the literature. METHODS: Cases operated under spinal anesthesia between January 2017 and December 2020 were investigated, and 617 patients who underwent simple lumbar disk surgery were included in the study. Demographic characteristics and American Society of Anesthesiologists (ASA) physical status of the patients were recorded. Visual analog scale (VAS) and QoLscores were obtained before and after the operation. RESULTS: There were 282 (45.7%) male and 335 (54.3%) female patients with a mean age of 39.48 ± 16.71 years (range: 18-58 years) at symptom onset. The mean operating time was 46.3 minutes (range: 22-68 minutes). Average blood loss was 85 mL (range: 55-125 mL). All the patients were mobilized 6 to 12 hours after surgery. In our patient group, there were both high- and normal-risk groups in terms of the ASA physical status. During the clinical follow-up, a statistically significant improvement was found for the VAS and QoL scores (p < 0.05). CONCLUSIONS: In this large retrospective study, our results have confirmed that spinal anesthesia is at least comparable to general anesthesia and even superior to it in some aspects.

Spinal anesthesia efficiency in thoracolumbar stabilizations.

Background and purpose:

Spinal surgery has an important place in neurosurgery practice. Surgical procedures on the lumbar spine include stabilization, discectomy, foraminotomy and decompression. Lumbar and lower thoracic spinal surgery can be safely performed under spinal anesthesia (SA). However, there are not many studies on the safety and efficacy of spinal anesthesia in patients who have undergone long segment stabilization surgery.

Patients who underwent lumbar and lower thoracic spinal instrumentation operations with general anesthesia (GA) or spinal anesthesia were included in the study. Demographic characteristics and American Society of Anesthesiologists (ASA) physical status of the patients were all recorded. Visual analog scale and quality of life scores were obtained before and after the operation.

572 patients with SA and 598 patients with GA were included in the study, 352 / 347 had only-lumbar region and 220 / 251 had thoracolumbar region operations, respectively. All patients underwent short/long segment stabilization. Mean operating time was 106.1 / 156.7 minutes. Average blood loss was 375 / 390 mL. All patients were mobilized 16-24 / 24-36 hours after surgery. In our patient group, there were both high-risk and normal-risk subgroups in terms of ASA physical status. During the clinical follow-up, a statistically significant improvement was found for VAS and quality of life scores for both groups (p<0.05).

Spinal anesthesia appears to be a very effective method in lumbar and thoracolumbar surgery. Along with careful patient selection, using this highly effective method provides a comfortable space for the surgeon.

Lymphangiectatic Variant of Low-Grade Malignant Eccrine Spiradenoma.

Low-grade malignant eccrine spiradenoma (spiradenocarcinoma) is a rare sweat gland tumor, which usually arises from a pre-existing benign eccrine spiradenoma. This paper presents the case of a 55-year-old male who had a lesion in his right elbow for 10 years. The microscopic examination revealed a well-demarcated, multilobulated tumor in the dermis and subcutis, which presented with many blood-filled vessels and extensive hemorrhage. The tumor was composed of hyperchromatic, round to oval cells with nucleolar prominence, mild to moderate atypia, and increased mitotic index. Additionally, lymphangiectatic appearance was observed in areas with prominent stromal lymphedema. P53 and Ki-67 had high positivity. Surgical excision of the lesion was performed with adequate surgical margins, and the dissected lymph nodes in the axilla were tumor-negative. After 15 months of follow-up, there was no recurrence or distant metastasis.

Effect of radiofrequency denervation on pain severity among patients with cervical, thoracic or lumbar spinal pain: A clinical retrospective study.

Background: Low back pain is the leading cause of job-related disabilities. The zygapophyseal (facet) joint has been identified as a cause of spinal pain in 15%-45% of individuals. Radiofrequency ablation (RFA) to the facet joints of the lumbar, cervical and thoracic regions and discussion of the 2-year follow-up results will provide additional data and contribute to understanding the long-term effectiveness of RFA. Methods: Patients with cervical, thoracic or low back pain, not accompanied by radicular pain and without primary and/or metastatic disease in the spinal region during radiological evaluation were retrospectively analysed. A total of 1274 patients aged >18 years who had clinical follow-up for at least 1 year and had back pain for >6 months were included in the study. The RFA groups were compared within themselves before and after the application. Moreover, patients who received RFA were compared with those who did not receive RFA (controls). The visual analogue scale and quality-of-life scores of the patients were evaluated. Periodic clinical follow-ups revealed changes in neurological status. Results: Of the 774 patients who underwent RFA, 156, 184 and 434 patients had pain in the cervical, thoracic and lumbar and lumbosacral regions, respectively. The control groups consisted of 108, 122 and 270 patients, respectively. No significant difference in any of the baseline demographic variables was observed between the groups (p > 0.05). A significant improvement was found in both visual analogue scale and quality-of-life scores when compared before and after RFA application within the groups. In addition, a significant improvement was found in the RFA group compared with the control group. Conclusions: As far as we know, this is the first comparative study of RFA involving the cervical, thoracic and lumbar spinal regions. RFA made it possible to obtain satisfactory results in all three regions. With its increasing popularity and frequency of use, new indications for RFA may emerge.

Hydatid Cyst of the Spine: A Rare Case Report

Hydatid cyst is a zoonotic disease that can affect multiple organs and is difficult to diagnose and treat. Spinal hydatid cyst (SHC) is a rare hydatid cyst involvement observed in 1% of all cases. It can induce various neurological symptoms depending on the region of the involvement. Paraplegia is one of the most prevalent neurological symptoms. In this case report, a 63-year-old male patient with bilateral lower extremity paraplegia was operated on by neurosurgery and diagnosed with SHC at the level of Th 11 vertebra in the pathological examination of surgically removed materials. Thus, we aimed to emphasize the significance of pathological and microbiological examination in the differential diagnosis of spinal disorders.

Democracy and COVID-19 outcomes.

More democratic countries are often expected to fail at providing a fast, strong, and effective response when facing a crisis such as COVID-19. This could result in higher infections and more negative health effects, but hard evidence to prove this claim is missing for the new disease. Studying the association with five different democracy measures, this study shows that while the infection rates of the disease do indeed appear to be higher for more democratic countries so far, their observed case fatality rates are lower. There is also a negative association between case fatality rates and government attempts to censor media. However, such censorship relates positively to the infection rate.

Important landmarks and distances for posterior fossa surgery measured by temporal MDCT.

In this retrospective study, we aimed to present important anatomical structures and distances for posterior fossa surgery by temporal multidetector computed tomography (MDCT). The temporal MDCT images of 317 adult patients (158 males and 159 females) were retrieved from the hospital's picture archiving and communication system (PACS). In the coronal temporal MDCT views, the cochlea-carotid canal and jugular bulb-mastoid bone outer surface were measured. In the axial MDCT views, the carotid canal-jugular bulb and carotid canal-posterior fossa distances were measured; the carotid canal and jugular bulb anterior-posterior (AP) and transverse dimensions were also measured. The bilateral cochlea-carotid canal, jugular bulb-mastoid bone outer surface, and right carotid canal-jugular bulb distances were significantly greater in the males than those in the females (p < 0.05). The carotid canal-posterior fossa distance was not different in both genders (p > 0.05). The carotid canal-jugular bulb and the carotid canal-posterior fossa distances were greater on the left side than those on the right side in both genders (p < 0.05). In males, the outer surface distance was greater on the left jugular bulb-mastoid bone than that on the right side of that bone (p < 0.05). The difference between the carotid canal AP dimensions was not significant between males and females (p > 0.05). However, the carotid canal transverse dimension, jugular bulb AP, and transverse dimensions were significantly greater in the males than those in the females, bilaterally (p < 0.05). In each gender separately, the carotid canal AP and transverse dimensions were greater on the left side and the jugular bulb AP and transverse dimensions were greater on the right side than those on the left side (p < 0.05). Positive correlations were found between the cochlea-carotid canal, the jugular bulb-mastoid bone outer surface, and the carotid canal-jugular bulb distances as well as between the jugular bulb-mastoid bone outer surface and the carotid canal-posterior fossa distances (p < 0.05). In older patients, the carotid canal-posterior fossa distances were shorter on the left side (p < 0.05). Vascular and neural localizations should be well understood in the operative area before applying the surgical approach in the posterior fossa. Computed tomography (CT) has a greater role in the evaluation of bone structures and vascular canals in this area.

Brachial artery thrombosis following bee sting, case report.

INTRODUCTION: Bee stings are the most common among insect emergencies. PRESENTATION OF CASE: We present a 47-year-old male patient who was admitted to the emergency department with complaints of pallor, chills, numbness and bruising on the left palm one hour after a bee sting on his left leg, and a very rare case of brachial artery stenosis in Dopler ultrasonography. DISCUSSION: Often bee stings occur only with local allergic reactions; sometimes it can also cause myocardial infarction, pulmonary edema, bleeding, hemolytic anemia, and kidney disease and neurological manifestations. Side effects are generally thought to be related to the dose of this venom in these patients who are admitted to the emergency room with a bruise extending from the left hand to the arm after bee bites. CONCLUSION: With this case presented, we wanted to emphasize that thrombosis may occur due to bee stings, albeit rarely, and doctors in emergency departments should recognize these very rare cases.

Inter-country distancing, globalisation and the coronavirus pandemic.

Originating in China, the coronavirus has reached the world at different speeds and levels of strength. This paper provides an initial understanding of some driving factors and their consequences. Since transmission requires people, the human factor behind globalisation is essential. Globalisation, a major force behind global well-being and equality, is highly associated with this factor. The analysis investigates the impact globalisation has on the speed of initial transmission to a country and on the scale of initial infections in the context of other driving factors. Our cross-country analysis finds that measures of globalisation are positively related to the spread of the virus, both in speed and in scale. However, the study also finds that globalised countries are better equipped to keep fatality rates low. The conclusion is not to reduce globalisation to avoid pandemics, but to better monitor the human factor at the outbreak and mobilise collaboration forces to curtail diseases.

Pneumorrachis and pneumocephalus associated with neck injury after stabbing.

BACKGROUND: Trauma-related pneumocephalus and subcutaneous emphysema are relatively common, but pneumocephalus and pneumorrachis that occur without surgery are very rare. We present a case of pneumorrachis and pnemocephalus developing in the literature for the first time after stabbing from the anterior cervical region and providing improvement with conservative treatment. CASE PRESENTATION: A 42-year-old male patient was brought to the emergency department after stabbed in the neck. Anteromedial injury of the sternocloid muscle was followed by two lacerations with active bleeding from the same site. The patient was unconscious (Glasgow coma score 8(E2, M4, V2). The patient was intubated. Bleeding foci and lacerations were repaired in the emergency. Cranial, cervical, thoracic and lumbar non-contrast computed tomography scans were performed. Moderate pneumocephalus was seen in the subarachnoid space in the anterior of the bilateral frontal lobe and in the suprasellar cistern region. Pneumorrachis was seen in C2-C7 levels of cervical spinal canal. The patient was pentotalized. 100% oxygen treatment for 6 h was given from the ventilator in intensive unit. After 72 h, cranial, cervical, thoracic and lumbar CT were performed. Pneumorrachis and pneumocephalus were fully recovered. CONCLUSION: Pneumorrachis is usually asymptomatic and is self-limiting. It is a radiological diagnosis and is not a clinical diagnosis. CT scan is considered the preferred diagnostic method for reliable and rapid detection of pneumorrachis. In case of coexistence, The physician should be alert to diagnose and treat the underlying cause for related injuries.In such cases, successful results can be obtained with hyper-oxy therapy (100% oxygen inhalation) and antibiotic prophylaxis without the need for surgical treatment.

A Detailed Biological and Chemical Investigation of Sixteen Achillea Species' Essential Oils via Chemometric Approach.

Representatives of the Achillea genus are widely used as foods or nutraceuticals. Considering the increasing demand for herbal dietary supplements with health promoting effects, the objective of this research was to evaluate the chemical composition and biological activities of the essential oils obtained from sixteen Achillea species (A. biebersteinii, A. wilhelmsii subsp. wilhelmsii, A. aleppica subsp. zederbaueri, A. vermicularis, A. monocephala, A. nobilis, A. goniocephala, A. sintenisii, A. coarctata, A. kotschyi subsp. kotschyi, A. millefolium subsp. millefolium, A. lycaonica, A. spinulifolia, A. teretifolia, A. setacea, and A. schischkinii). Anticholinesterase, antiurease, antityrosinase enzymes inhibition, antioxidant, antimicrobial, toxic and cytotoxic activities of obtained essential oils were investigated. DPPH activities were found to be very low in all studied samples, while ABTS and CUPRAC antioxidant activities were found to be moderate. In addition, all samples were found to have moderate anticholinesterase and antimicrobial effects. It has been determined that the studied species have low cytotoxicity and high toxicity. Besides, chemical composition of the essential oils were determined by GC/MS and the results were chemometrically analyzed. The chemometric analyses of Achillea species collected from nine different regions were accomplished by principal component analysis (PCA) and hierarchical cluster analysis (HCA) techniques. According to the PCA analysis, A. nobilis subsp. neilreichii was found to be different from all studied species in terms of essential oil composition. The major components found in these species were piperitone, camphor, α-terpinene, eucalyptol, artemisia ketone, endo-borneol, ß-eudesmol and verbenol. The fact that camphor was toxic and found in majority of the studied species stands out as a remarkable result.

Modifying inter-cistronic sequence significantly enhances IRES dependent second gene expression in bicistronic vector: Construction of optimised cassette for gene therapy of familial hypercholesterolemia.

Internal ribosome entry site (IRES) sequences have become a valuable tool in the construction of gene transfer and therapeutic vectors for multi-cistronic gene expression from a single mRNA transcript. The optimal conditions for effective use of this sequence to construct a functional expression vector are not precisely defined but it is generally assumed that the internal ribosome entry site dependent expression of the second gene in such as cassette is less efficient than the cap-dependent expression of the first gene. Mainly tailoring inter-cistronic sequence significantly enhances IRES dependent second gene expression in bicistronic vector further in construction of optimised cassette for gene therapy of familial hypercholesterolemia. We tailored the size of the inter-cistronic spacer sequence at the 5' region of the internal ribosome entry site sequence using sequential deletions and demonstrated that the expression of the 3' gene can be significantly increased to similar levels as the cap-dependent expression of the 5' gene. Maximum expression efficiency of the downstream gene was obtained when the spacer is composed of 18-141 base pairs. In this case a single mRNA transcriptional unit containing both the first and the second Cistron was detected. Whilst constructs with spacer sequences of 216 bp or longer generate a single transcriptional unit containing only the first Cistron. This suggests that long spacers may affect transcription termination. When the spacer is 188 bp, both transcripts were produced simultaneously in most transfected cells, while a fraction of them expressed only the first but not the second gene. Expression analyses of vectors containing optimised cassettes clearly confirm that efficiency of gene transfer and biological activity of the expressed transgenic proteins in the transduced cells can be achieved. Furthermore, Computational analysis was carried out by molecular dynamics (MD) simulation to determine the most emerges as viable containing specific binding site and bridging of 5' and 3' ends involving direct RNA-RNA contacts and RNA-protein interactions. These results provide a mechanistic basis for translation stimulation and RNA resembling for the synergistic stimulation of cap-dependent translation.

Is there a relationship between basilar artery tortuosity and vertigo?

OBJECTIVE: The aim of this study was to investigate the relationship between basilar artery (BA) tortuosity, hypogenesis/agenesis of the vertebral artery (VA), and vertigo, with the use of magnetic resonance imaging (MRI). PATIENTS AND METHODS: This case-control study included patients admitted to the outpatient clinics, who were aged 18-80 years, without any known systemic diseases. All patients were evaluated with a 1.5-tesla MRI system. BA Tortuosity, VA agenesis, and VA asymmetry were noted. BA diameter (central) and length (longitudinal) were measured. RESULTS: A total of 154 vertigo patients (46 M, 108 F; mean age of 48.95 ± 17.3 years) and 346 control subjects (112 M, 234 F; mean age of 45.12 ± 17.0 years) were included. The mean age of the vertigo patients was significantly higher than that of the control group (48.95 vs 45.12 years) (p = 0.021). The rate of BA tortuosity was higher in patients with vertigo (p = 0.030). When the participants were divided into two groups according to median age (<45 vs. ≥45 years) there was no statistically significant difference between the groups in terms of VA asymmetry (p = 0.070) and hypogenesis/agenesis (p = 0.577). There was a statistically significant difference between the groups in respect of BA tortuosity (p = 0.033), BA diameter (p < 0.001), and BA length (p < 0.001). When the study populations were divided into two groups according to the presence of vascular tortuosity, the mean age, BA diameter, and BA length values were higher in the tortuosity (+) group (all p < 0.001). CONCLUSION: These results demonstrated that vertigo and BA tortuosity rates seem to increase with age. Likewise, BA diameter and length increased with age, although there was no significant relationship with vertigo. Patients with tortuosity were significantly older, and had higher rates of VA asymmetry/agenesis, and increased BA diameter compared to subjects without tortuosity.

Sonoelastographic evaluation of the sciatic nerve in patients with unilateral lumbar disc herniation.

OBJECTIVE: The aim of this study was to compare strain elastography (SE) and shear wave elastography (SWE) findings of the sciatic nerve in patients with unilateral lumbar disc herniation (LDH) and healthy control subjects. MATERIALS AND METHODS: The study group included patients with complaints of unilateral sciatica for 3-12 months, with foraminal stenosis due to one level of LDH (L4-L5 or L5-S1). An age- and gender-matched control group was formed of healthy subjects. Evaluations were performed on both the axial and longitudinal planes from the bilateral gluteal region using a 5-9 MHz multifrequency convex probe. RESULTS: There were 40 patients (20 male, 20 female) with a mean age of 43.1 ± 12.7 years in the study group, and 40 healthy subjects (22 male, 18 female) with a mean age of 42.9 ± 10.7 years in the control group (p > 0.05). The sciatic nerve stiffness assessed on both the axial (12.3 ± 3.7 kPA) and longitudinal (14.3 ± 3.8 kPA) planes of the involved side was significantly higher than non-involved side (axial: 6.8 ± 2.1 and longitudinal: 8.3 ± 2.3 kPA) in the patient group (p < 0.001). CONCLUSIONS: Patients with unilateral LDH have increased stiffness of the sciatic nerve compared to healthy control subjects. Although the findings in this preliminary study show that shear wave elastography can detect a change in sciatic nerve stiffness in patients with unilateral LDH, larger studies are required to determine the clinical utility of this technique.

An Evaluation of the Quality of Sleep Before and After Surgical Treatment of Patients with Cervical Disc Herniation.

OBJECTIVE: It has been reported in recent studies that 50-80% of patients with cervical disc hernia have concomitant sleep disorders. The aim of this study was to evaluate the quality of sleep before and after surgical treatment in patients with cervical disc hernia and to assess the effects on treatment. METHODS: The study included 32 patients performed discectomy and fusion with an intervertebral cage through the right anterior cervical approach. Oswestry Disability Index (ODI), Visual Analog Scale (VAS) and Pittsburgh Sleep Quality Index (PSQI) were applied to all patients preoperatively and at one month postoperatively. RESULTS: The postoperative PSQI total points and all the PSQI subscale points, the ODI and VAS scores were significantly reduced compared to the preoperative values. A positive correlation was determined between the preoperative ODI points and the PSQI total points and sleep duration, sleep latency and daytime functional loss subscale points. A positive correlation was also found between preoperative ODI points and VAS points. A positive correlation was determined between the preoperative VAS points and and the PSQI total points and sleep duration, and sleep latency subscale points. A negative correlation was determined between the postoperative ODI and the daytime functional loss subscale points. CONCLUSION: The results of the study showed that in patients with cervical disc hernia, sleep quality and daytime functionality were negatively affected by severity of pain that limited daily activities. Bringing the pain under control with surgical treatment was observed to increase sleep quality. It can be concluded that when planning treatment for these patients, it should be taken into consideration that there could be a sleep disorder in addition to the complaints and symptoms such as pain, hypoestesia and loss of strength.

Fas-ligand and interleukin-6 in the cerebrospinal fluid are early predictors of hypoxic-ischemic encephalopathy and long-term outcomes after birth asphyxia in term infants.

BACKGROUND: Cerebral ischemia generates neuroinflammation that can induce neural cell death. This cohort study assessed whether Fas-ligand (FasL) and interleukin (IL)-6 levels in the cerebrospinal fluid (CSF) after hypoxic-ischemic encephalopathy (HIE) can serve as biomarkers of hypoxic brain injury in neonates. METHODS: Term infants (> 37-week gestational age) who were admitted to the neonatal intensive care unit of Karolinska University Hospital in years 2002 to 2004 with perinatal asphyxia were enrolled prospectively. Control infants without brain pathology underwent lumbar puncture for suspected infection. FasL and IL-6 levels were measured in the CSF, by enzyme-linked immunosorbent assays. All patients underwent neurological assessment at 18 months. HIE was classified as mild, moderate, or severe (HIE I-III). Adverse neurological outcome at 18 months was defined as a mental developmental index < 85, deafness, blindness, cerebral palsy, or seizure disorder. RESULTS: Of the 44 HIE patients, 14, 16, and 14 had HIE-I, HIE-II, and HIE-III, respectively. HIE-II and HIE-III patients had higher FasL and IL-6 levels than HIE-I patients and the 20 controls (all p < 0.0001). Patients with adverse outcomes had higher FasL and IL-6 levels than patients with normal outcomes and controls (both p < 0.0001). On receiver-operator curve analyses, FasL and IL-6 (alone and together) were highly predictive of HIE grade and outcome (areas under the curve range 0.86-0.94) and showed high sensitivity (66.7-100%). These biomarkers performed better than cord blood pH (areas under the curve: HIE grade = 0.80, adverse outcomes = 0.86). CONCLUSION: CSF biomarkers FasL and IL-6 predicted severity of encephalopathy and long-term outcomes in post-asphyxiated infants better than a standard biomarker.
